Apnea
Betsy S. Kastak DNP, RN C-PNP + Santa J. Bartholomew MD

Apnea is defined as a pause in the regular breathing pattern during sleep. The causes are many; however, the results are similar in that the interruption of breathing burdens the individual’s respiratory, cardiovascular, and neurological systems. This burden is cumulative over time.

kinds of apnea

There are three general kinds of apnea:

Obstructive Sleep Apnea is breathing blocked by an “obstruction” of the upper airway while chest and abdominal muscles keep attempting to breathe.
- shallow breathing, snoring with big gasps
“Central” Sleep Apnea
- breathing takes a pause, the brain “skips a beat”
Hypopnea
- reduction in breathing of about 50%, shallow breath, due to a partially obstructed airway
- small change in oxygen level
- shallow breath
- Rarely requires intervention

Apnea in Children

Pediatric obstructive sleep apnea syndrome (OSAS) is a sleep disorder in which a child’s breathing is partially or entirely blocked repeatedly during sleep. The condition is due to narrowing or blockage of the upper airway. The prevalence of OSAS ranged from 0% to 5.7%, with obesity being an independent risk factor. OSAS can be associated with cardiovascular issues, growth, neurobehavioral abnormalities, and possibly inflammatory changes in the body.

Children with OSAS are most likely to demonstrate behavioral problems unlike their adult counterparts how usually show daytime sleepiness. No matter how OSAS is revealed in adults and children it may residual complications if not treated.

The most common underlying condition in children is the enlargement of the adenoids and tonsils. Therefore, the primary treatment is typically adenotonsillectomy (AT). Usually, this results in significant improvements in behavior and attention and can also improve cognitive abilities. Although OSAS will often improve postoperatively, children may have residual problems, especially if they are in the “obese” category on the BMI scale.

Following an adenotonsillectomy (AT), if residual obstruction remains, is one common therapy used to treat the issue:

CPAP (continuous positive airway pressure): a machine that delivers a steady stream of air. The airstream pushes against any obstructions, maintaining an open airway for breathing. CPAP machines are used to treat OSAS.
- Though respiratory therapy may be effective in treating OSAS, adherence is a significant barrier for children. For this reason, CPAP is not recommended as first-line therapy for OSAS when AT is an option.

Children with Down syndrome are most vulnerable to obstructive sleep apnea because of their unique craniofacial anatomy and hypotonia (poor muscle tone).

Smaller mid-face: typically, people with Down syndrome have a smaller upper jaw, and/or nose.
- A smaller jaw makes the tongue seem larger and this can cause an obstruction.
Decreased pharyngeal muscle tone: pharyngeal muscles are the muscles that support breathing, and those muscles can be weaker in people with DS.

Timely recognition and treatment of OSA in this population of children is an important to achieve optimal cognitive function and quality of life. Although guidelines recommend routine OSA screening in young children with Down syndrome, it can be difficult to perform, and the results are often uncertain.

The National Down Syndrome Society (NDSS) promotes awareness of OSA for individuals with Down Syndrome. Their website states: “There is a 50-100% incidence of obstructive sleep apnea in individuals with Down syndrome, with almost 60% of children with Down syndrome having abnormal sleep studies by age 3.5 -4 years.”

In 2011, the American Academy of Pediatrics recommended that all children with Down syndrome have polysomnography, or a sleep study, by four years of age. The sleep study consists of a night of observed sleep during which professionals measure brain waves, the oxygen level in the blood, heart rate, breathing, and eye and leg movement. Children who cannot have a sleep study PSG due to lack of access or inability to tolerate the conditions may have a home sleep study or pulse oximetry as an initial screening.

CPAP and BiPAP machines are typically life-long treatments. Although many individuals with Down syndrome adjust to using the CPAP during sleep, some cannot tolerate wearing the facial mask and require alternative therapies.

Research suggests that OSAS is also a risk factor other diseases:

Reactive airways with bronchoconstriction
- Research confirms that asthmatic patients are more prone to develop OSAS symptoms than people who do not have asthma
- Nasal obstruction due to allergies is one of the characteristics of asthmatics that increase OSAS symptoms and increase the collapse of the upper airways
Gastroesophageal reflux
Generalized inflammation of airways
OSAS-induced cardiac dysfunction have been proposed as factors that worsen asthma control.

Neonatal apnea is a condition that affects both term and pre-term infants for various reasons, though it is more common in preterm infants. Unlike periodic neonatal breathing that combines a regular respiratory pattern and respiratory pauses, neonatal apnea and apnea of prematurity are defined as the absence of breathing for more than 20 seconds.

Clinical manifestations of neonatal apnea require careful management, including invasive or noninvasive treatment, ventilation, monitoring, and pharmacology intervention to prevent acute and long-term complications. When a neonate, preterm or not, has a classic apneic event, they will cease breathing for 15-20 seconds and have no respiratory effort. This may be accompanied by bradycardia and some oxygen desaturation; the baby will also bluish tint to the skin.

This is one of the more common conditions diagnosed in the neonatal intensive care unit. Apnea is caused by immaturity of the neurological system and weakness of the muscles that keep the airway open. At times, additional stresses, specifically in a premature baby — including infection, heart or lung problems, low blood count, low oxygen levels, temperature problems, feeding problems, and overstimulation, may cause or enhance incidents of apnea. Recurrent apnea can lead to respiratory failure, pulmonary hemorrhage, abnormal heart and lung function, intracranial hemorrhage, abnormal nervous system development, and even sudden death.

Caffeine citrate has been used for treating apnea since 1970 due to it’s excellent bioavailability and paucity of side effects. Varying doses of caffeine citrate for apnea have been proposed. The safe and effective amount of low and high caffeine citrate maintenance doses for apnea treatment of premature infants has been determined by analysis of multiple clinical studies. Higher-maintenance doses of caffeine citrate appear more effective than low-maintenance doses for the treatment of apnea despite a high incidence of tachycardia.

Central sleep apnea (CSA) is less common than neonatal or obstructive sleep apnea. It is a pause in breathing during sleep, usually without snoring or gasping. Everyone experiences central apneas occasionally. However, if it occurs too frequently or for long periods, it can cause a decrease in the oxygen levels in the body, disrupt sleep and impact neurologic development in children.

Central sleep apnea is caused by increased sensitivity to the partial pressure of CO2 in the system that regulates the respiratory drive. CSA commonly presents as cycles of deep, rapid, crescendo decrescendo breathing (hyperpnea), followed by slower, shallower breathing (hypopnea) or no breathing without respiratory effort from the diaphragm (apnea), known as Cheyne-Stokes breathing.

The cause of CSA in children is either idiopathic or due to a profound neurological insult at birth or after. CSA can lead to systemic and pulmonary hypertension, arrhythmias, and cardiovascular collapse is untreated.

Characteristics of central sleep apnea include:

Observed episodes of pauses in breathing or abnormal breathing patterns during sleep
Abrupt awakenings followed by shortness of breath
Frequent awakenings in general
Headaches in the morning
Difficulty focusing and concentrating
Daytime sleepiness (if sleep is disturbed)

BiPAP machines offer three air-pressure settings which include spontaneous switching that senses breathing patterns and adjusts accordingly, timed switching which is better for those who need a regular rate and spontaneous timed switching that is a mix of both. BiPAP is better for those with central sleep apnea since they assist with air trapping and can provide a backup respiratory rate when the patients has to long a period of apnea.

Monkeypox

PME-Admin article, medical children, infants, monkeypox, pediatric, pediatrics

Monkeypox
Cynthia D. Read, CPNP-PC, LNC & Santa J. Bartholomew MD

The World Health Organization (WHO) has recently recommended “mpox” to be the new preferred term/synonym for Monkeypox. Both the Centers for Diseases control (CDC) and Health and Human Services (HHS) have adopted “mpox” as the new term used for Monkeypox.

Monkeypox is a virus belonging to the Orthopoxvirus genus in the Poxviridae family. Monkeypox primarily occurs in west and central Africa, often close to tropical rainforests. The first outbreak of Monkeypox outside of Africa occurred in 2003 in the United States. Since that time, Monkeypox has continued to be reported in several areas of the world including the United States.

A 7-year-old Zairian girl with monkeypox in the acute stage, day 7 of rash, and monkeypox in a 3-year-old Zairian boy with rash in the scabbing stage, DRC, 1970-1977. WHO / Mark V. Szczeniowski.

Signs and Symptoms of Monkeypox

Symptoms of Monkeypox are similar to those of smallpox, but often less severe. The time from infection to the onset of symptoms (Incubation period) can range from 5 to 21 days, but is usually 6 to 13 days.

Two Phases of Infection

The Invasion Period: Lasts 0-5 days. Characterized by intense headaches, fever, swelling of the lymph nodes, muscle aches, back pain, extreme fatigue. Swelling of the lymph nodes is a primary feature of monkey pox not generally seen with other similar illnesses such as chickenpox, smallpox, and measles.
The Skin Eruption Period: Usually appears 1-3 days following fever. The rash is usually seen more on the face, arms and legs rather than the trunk. Affects the face (95% of cases), palms of hands and soles of feet (75% of cases), oral mucous membranes (70% of cases), genitalia (30% of cases), conjunctivae (20% of cases) and cornea. The rash starts as flat lesions progressing to raised, firm lesions. These lesions then become filled with a yellowish fluid which then dry up and fall off. The number of lesions may vary from a few to thousands.

Monkeypox is a self-limiting disease. Symptoms generally lasts 2-4 weeks. Severe cases are more common in children. Severity of the illness is related to the extent of the exposure to the virus.

Complications of Monkeypox

Secondary infections, pneumonia, overwhelming infection/sepsis, encephalitis, infection of the cornea leading to vision loss.

Cleveland Clinic. (2022, June 17). Monkeypox: Causes, Symptoms, Treatment and Prevention. Cleveland Clinic. https://my.clevelandclinic.org/health/diseases/22371-monkeypox.

How is Monkeypox Transmitted

Transmission may occur from the mother to fetus via the placenta. This can lead to congenital monkeypox. Transmission may also occur due to close contact during and after birth. The risk of children and adolescents being infected with the monkeypox virus is low. Infants, children and adolescents may be at an increased risk of contracting Monkeypox if they suffer from eczema, other skin conditions, or immunocompromising illnesses.

Various animals have been identified as being susceptible to the monkeypox virus and therefore, becoming hosts for the disease. Animals included are rope squirrels, tree squirrels, Gambian pouched rats, dormice, non-human primates and several other species.

Transmission from animal-to-human may occur through direct contact with blood, body fluids, or skin or mucosal lesions of infected animals. Possible risk factors include eating meat that has not been cooked adequately and other animal products of infected animals.

Human-to-human transmission may also occur. This can result from close contact with respiratory secretions, lesions of the skin of an infected person, or touching recently contaminated objects. Transmission via respiratory droplets requires a prolonged length of time having face-to-face contact. This places health care workers, family members and other close contacts of active cases at an increased risk.

Diagnosis and Treatment

It is important to consider other similar illness when diagnosing:

Other rash illnesses (chickenpox, measles, bacterial skin infections, scabies, syphilis, allergies from medications)

Diagnosis by PCR is the preferred laboratory test. Fluid from the vesicles/pustules and dry crusts. Biopsy may also be taken. PCR blood test often inconclusive. Previous vaccination with smallpox vaccine or monkeypox vaccine may result in false positive results.

Treatment includes

Alleviating symptoms, managing complications and preventing long-term sequelae.
Fluids and food are important to maintain good nutritional status.
Secondary bacterial infections will also need to be treated.
An antiviral (tecovirimat) was developed for smallpox and licensed by the European Medicines Agency (EMA) for monkeypox in 2022. This was based on data from animal and human studies. Not yet widely available

Prognosis

In the past, fatality ranged 0-11% (higher among young children). More recently, 3-6%.

Vaccination

Smallpox was eradicated in 1980 and there was subsequent cessation of the smallpox vaccine. Being vaccinated against smallpox has been shown to be approximately 85% effective in preventing monkeypox. Due to no longer manufacturing the smallpox vaccine, persons under 40 to 50 years of age may be more susceptible to monkeypox.

A newer vaccine was approved in 2019 for the prevention of monkeypox. This is a two dose vaccine, but availability is limited.

Extubation Failure

PME-Admin article, medical breathing issues, children, extubation, infants, pediatric, pediatrics, ventilator

Extubation Failure
Santa J. Bartholomew MD

Mechanical ventilation is often required for critically ill patients in the ICU. As the acute phase of illness resolves, the goal is to wean the ventilator, allowing the patient to breathe more on their own (spontaneous breathing trials), and to successfully extubate, or remove the artificial airway. Patients may tolerate weaning the ventilator, but fail extubation. Extubation failure is defined as the inability to sustain spontaneous breathing after the removal of the artificial airway (an endotracheal tube or tracheostomy tube) and require reintubation within a specified time period, usually defined as 24-72 hours or up to 7 days.

Causes of Extubation Failure

Excessive secretions affecting airway patency
Respiratory Failure: Most common cause. Manifest as increased work of breathing, hypoxia (insufficient oxygen), hypercapnea (excessive carbon dioxide in the blood), use of accessory muscles for breathing, respiratory acidosis
Upper airway edema affecting patency of airway
Neurological impairment: May be secondary to primary illness, encephalopathy, or residual effects of sedation
Neuromuscular Diseases (Guillain-Barre syndrome, Duchenne Muscular Dystrophy)
Acute heart failure
Poor nutrition
Other risk factors: Severity of illness on admission to ICU, prolonged intubation, continuous sedation

It is essential for the Health Care Provider to identify patients at a higher risk for extubation failure/need for re-intubation, as extubation failure can have detrimental consequences. It is also imperative that all appropriate equipment and personnel are on hand for difficult extubation.

Consequences of Extubation Failure

The incidence of extubation failure has been noted to be between 6% and 47%. Nosocomial pneumonia is significantly increased in patients failing extubation (47% versus 10%). Additional consequences of extubation failure are:

Prolonged ICU stay and hospitalization
Prolonged mechanical ventilation
Need for tracheostomy
Increased medical cost
Increased morbidity and mortality

Mortality is increased with increasing duration of time between extubation and reintubation. This is due to deterioration in the patients’ condition leading to organ dysfunction and failure.

Predictors of Extubation Failure

There are many risk factors for extubation failure. It is vital for the Healthcare Provider to do a thorough assessment of extubation readiness. Parameters that are used to predict failure of extubation are often categorized into parameters assessing respiratory mechanics, airway patency and protection of airway, and cardiovascular reserve. Successful extubation is dependent on adequate cough strength, minimal secretions, and mental alertness or the neurological ability to maintain adequate spontaneous breathing.

Successful spontaneous breathing trials: These trials allow the patient to breath more on their own while the artificial airway remains in place. This allows the Healthcare provider to better assess respiratory muscle reserve/weakness and work of breathing
Adequate cough strength: Important for patient to be able to clear airway of secretions. This may be affected due to weak respiratory muscles and laryngeal dysfunction
Secretions: Excessive secretions or the patient’s inability to handle their secretions
Neurological Dysfunction: Study results vary on the impact of neurological impairment on extubation failure. Most recently, a GCS ≥10 is prerequisite for successful extubation
Cuff leak: Laryngeal edema and airway obstruction following extubation may lead to extubation failure. When the cuff on the artificial airway is deflated, the amount of leak noted depends on the degree of laryngeal and airway edema. Glucocorticoids (steroids) are often administered prior to extubation to reduce airway edema
Vital Signs and Blood Gases: Spontaneous breathing requires the heart to work harder. Patients with poor heart function or following cardiac surgery may be at an increased risk for failing extubation. An increase in heart rate and respiratory rate during spontaneous breathing trials may be an indicator of extubation failure. Other findings may include an increase in lactic acid, an increase in PaCO2 (carbon dioxide) in the blood, a decrease in the blood pH (indicating acidosis), or decreased oxygen content in the blood.

Predictors of extubation failure may not apply to neurologically injured patients as the ability to protect their airway and clear secretions may be impaired independently of their ability to ventilate.

Management of Failed Extubation

Extubation failure is a common occurrence in the ICU. Even with successful spontaneous breathing trials, patients remain at risk for extubation failure following removal of the artificial airway due to other factors and circumstances.

Nasal Intermittent Mandatory Ventilation (NIMV)/Intermittent Mandatory Ventilation (IMV): Use of NIMV/IMV has been shown to provide the additional respiratory support needed to avert/prevent reintubation in some patients.
High-Flow Nasal Cannula: Treatment for hypoxemic acute respiratory failure. Delivers a high flow/fraction of inspired oxygen (FiO2) and generates a low level of positive pressure. This provides support for patients with weak respiratory muscles and improves the work of breathing and respiratory rate.
Oxygen alone should not be used to correct hypoxemia that is caused by hypoventilation (ineffective breathing and ventilation). In doing so, the respiratory drive can be suppressed and precipitate acute respiratory failure
Steroids: Edema of the upper airway is difficult to assess before extubation. Upper airway edema is a risk factor for reintubation. Evaluating for a cuff leak prior to extubation predicts stridor but not the need for reintubation. In a double blinded trial, four (20 mg) doses of prophylactic use of methylprednisolone initiated 12 hours before extubation at 4 hour intervals versus placebo, resulted in reduction (22% to 3%) of laryngeal edema and reduction in reintubation (8% to 54%) due to laryngeal edema.

Evidence is suggestive that prophylactic administration of glucocorticoids and early institution of non-invasive ventilation may prevent reintubation in some patients. If necessary, early reintubation and reinstitution of ventilation should be instituted.

Headaches in Children

PME-Admin article, medical brain tumor, children, headaches, herpes simplex virus, infants, pediatric, pediatrics

Headaches in Children
Santa J. Bartholomew MD

Headache known as pain above the orbitomeatal line is one of the most common complaints in children and young people. The prevalence of headaches increases with age and greatly impacts school attendance for the child and work attendance for parents. The primary concern for caregivers always being brain tumor. Headaches are estimated to occur in 75% of adolescents and 25% of younger children with migraine being the most common reason for a child to see a neurologist.

Thorough headache history and focused neurological examination are critical in evaluating headaches and distinguishing between primary headaches such as migraine, tension and chronic daily headache and secondary headaches such as those that occur with brain tumors, other causes of intracranial hypertension such as pseudotumor cerebri, meningitis, hydrocephalus from any cause. Acute febrile illnesses can also cause headache and essential hypertension. Classification of headache disorders have been established by the International Headache Society in 2013 and following these guidelines can help practitioners arrive at appropriate treatment plans for the particular headache the child is suffering from.

GETTING A HEADACHE HISTORY

History needs to be gotten from parent AND child. Of course, questions need to be developmentally appropriate.
Essential information in headache history
- When did headaches first begin?
- Location of the pain.
- Quality of the pain.
- Severity of the pain, has the pain remained the same or getting worse.
- Are there other symptoms such as focal weakness, sensory or visual disturbances, vomiting, light intolerance, double vision?
- Are headaches chronic or episodic? Frequency and duration of headache?
- How long have headaches been occurring?
  - If headaches are long-standing has there been a change in the quality or position of the headache?
- Can you tell the headache is coming on?
- Has the headache every woken you up at night?
- Have you ever had a seizure with the headache?
- Are there activities or foods or medications that make the headaches worse?

The Orbitomeatal Line

Focused Neurologic Examination

Although there is consensus on how to achieve historical data about history of headache through the International Headache society and the use of tools such as the Pediatric Migraine Disability Assessment (PesMIDAS) there is little consensus on the evaluation of these complaints.

Most agree that at the least an examination should include:

Assessment of the immunocompetence of the child
Fever
Careful cranial nerve examination: nuchal rigidity, swelling of scalp, sinus tenderness, TMJ tenderness, posterior neck pain (sometimes seen in Chiari malformation), thyromegaly, muscular tightness.
Palpation of head and neck:
Assessment of gait and reflexes
Careful examination of spine
Careful examination of skin looking for signs of neurocutaneous disorders such as tuberous sclerosis. Neurofibromatosis.
Assessment of the retina with full visualization of the optic nerve
Auscultation of eyes, neck and head for bruits
Assessment of oropharynx looking for tooth decay or tonsillar abscess

Diagnostic studies:

Neuroimaging: may be considered when headache is subacute but rapidly progressive in severity, new onset of HA in immunocompromised child, presence of systemic findings like nuchal rigidity or fever, abnormal neuro examination in a new onset headache, headaches awakening a child from sleep.
- Neuroimaging should also be considered in all children WITHOUT a family history of primary headache disorders.
EEG: not recommended in routine evaluation of headache in children as diagnostic yield is usually low.
Lumbar puncture: not routinely recommended unless clinical presentation suggests infectious etiology to headache.
Lab testing: often unnecessary in assessment of primary headache disorder unless there is suspicion of an underlying cause such as hyperthyroidism, severe anemia.

Primary Headaches

Migraines:
- Intermittent attacks of headaches characterized by recurrent episodes of moderate to severe head pain lasting 2 to 72 hours.
- Usually, bifrontal or bitemporal
- Pain is usually focal, throbbing and worsens with activity.
- Can be accompanied by nausea, light sensitivity, and sound sensitivity
- 10% of children have an aura
- Treatment occurs in tiers:
  - I: Analgesics such as Tylenol, Ibuprofen, Naproxen are the initial treatment for treatment naïve children
  - II: Triptans: for children at least 5 years old and who have moderate to severe attacks. These are dosed by age, weight and ability to swallow a pill
  - III: Multiple drug therapy: For children>5 years old who have refractory to monotherapy migraines. Suggestion is a tier I and II drug in combination.
- Chronic Migraine
  - Migraine that occurs 15 or more days a month with at least 8 of the headaches having migraine features.
  - More common in females than males.
  - Overall prevalence in middles school to high school aged children is 1.5%
  - Avoidance of overuse of medication is important step in prevention of chronicity.
- Tension Headaches
  - Characterized by diffuse location, non-throbbing, mild to moderate in severity and does not worsen with activity.
  - Typically last 30 min to 7 days and may be associated with light or sound sensitivity but symptoms do not include an aura, nausea or vomiting
  - Acute treatment is with tier I drugs although gabapentin and Topamax have been used as medication alternatives.
  - Prevention is accomplished with lifestyle modification: healthy habits such as not skipping meals, limiting caffeine consumption, good sleep hygiene.

Cluster Headaches: constitute the most common trigeminal nerve headache. It is usually along the trigeminal nerve location.

Pain is usually severe but lasts < than 3 hours. But multiple episodes of headache can occur during that time.

- They are often one-sided and in addition to headache the sufferer may have watery eyes, injection of the conjunctivae, runny nose or congestion, facial and forehead sweating, eyelid edema or droopy eyelid and changes in pupil response.
- Acute therapy includes: oxygen in an ED or urgent care setting or SQ sumatriptan or in patients who cannot administer an injection then IN sumatriptan.
- Patients who do not respond to these simple therapies may be treated with intranasal lidocaine of oral ergotamine’s
- Prevention should be initiated immediately for cluster headaches, and this includes preventative therapy with Verapamil or in active clusters glucocorticoids may help.
- Lithium and Topamax have also been used in combination with other drugs for refractory headaches.

Secondary Headaches

Headaches caused by an underlying condition.

Acute febrile illness
- Rhinosinusitis
- Meningitis: acute or chronic
- Encephalitis
Post-Traumatic headaches
- Intracranial hemorrhage from trauma: epidural, subarachnoid or subdural hematoma
- Concussions
Side effect of medications
Headache medication overuse
Severe and acute systemic hypertension (very high blood pressure)
Brain tumor
Idiopathic Intracranial hypertension: pseudotumor cerebri
Hydrocephalus

In these cases head history usually sorts these patients from primary headache sufferers and physical examination provides clues to etiology of headache for example changes n mental status or gait disturbances, abnormal fundoscopic examination.

Diagnostics: imaging often is needed and helps identify the cause of the headache and when cause is identified then treatment can be determined.

Pediatric Encephalitis

PME-Admin article, medical children, encephalitis, infants, pediatric, pediatrics

Pediatric Encephalitis
Santa J. Bartholomew MD & Cynthia D. Read, LNC

Pediatric Encephalitis is an altered mental status for more than 24 hours that is accompanied by two or more symptoms/findings that are concerning for inflammation of the brain parenchyma. The brain parenchyma is the tissue responsible for specific functions of the brain. The incidence of pediatric encephalitis is unclear, due to multiple etiologies and inconsistent definitions of encephalitis. Recent reports do indicate that cases of pediatric encephalitis may be increasing due to increased recognition of autoimmune etiologies and use of magnetic resonance imaging (MRI) to describe abnormalities in the brain parenchyma. Up to 30% of cases of pediatric encephalitis have an undiagnosed etiology.

How does Encephalitis happen?

Encephalitis is inflammation of the brain. This can be caused by an infection or an autoimmune cause. The inflammation is the body’s immune system reacting to the infection or invasion. The inflammation causes the brain’s tissues to become swollen. The infection can get into the cerebral spinal fluid (CSF).

In the past, infectious agents accounted for most of the etiologies for encephalitis. Before the use of vaccinations, measles, mumps, varicella and polio were among the top causes for encephalitis. With the introduction of vaccines, other viral etiologies such as herpes simplex virus (HSV) and enterovirus (EV) have risen to the top of etiologies for infectious encephalitis in pediatrics.

In autoimmune encephalitis, the body’s immune system attacks the brain causing inflammation. The number of cases of autoimmune encephalitis are beginning to outnumber those of viral encephalitis, with the incidence of anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis exceeding the rate for a single viral etiology for pediatric encephalitis.

Pediatric Medical Experts Encephalitis in Children from Tick Bites

Causes

Herpes Simplex Virus: Most common cause of pediatric encephalitis. Estimated incidence 3 to 30 cases per 100,000 live births. Serious morbidity and mortality. Transmitted intrauterine, perinatal, and postnatal
Enterovirus: Among top causes of pediatric encephalitis
West Nile Virus: Most common arbovirus in North America (virus spread to people by the bite of an infected arthropod/insect such as mosquitoes and ticks). <4% of cases involve children <18 years old. Transmitted by culex mosquito and therefore, mostly seen in summer
La Crosse Virus: Second most common arbovirus in North America. 88% of all encephalitis due to La Crosse virus occurs in children <18 years of age. Most cases in Appalachian and Midwestern region of US. Usually seen in late spring through early fall. Transmitted via infected Aedes mosquito
Zika Virus: Can cause microcephaly (small head and abnormal brain development) in infants. Transmission via infected Aedes mosquito. Seen in summer and early fall.
Bacteria: Streptococcus pneumoniae, haemophilus influenzae serotype b, Neisseria meningitidis, Listeria monocytogenes, mycoplasma
Autoimmune diseases

SYMPTOMS

Symptoms may be similar for infectious and autoimmune encephalitis. A consensus statement provided by the International Encephalitis Consortium outlines diagnostic criteria for possible and confirmed encephalitis. Per this consensus statement, a requirement for encephalitis is altered mental status for >24 hours without an alternative diagnosis, and 2 or more of the additional clinical features mentioned below:

Fever: >100°F (>38°C) within 72 hours
Seizures: New onset or different than pre-existing seizure history
New focal neurologic findings
Cerebrospinal fluid (CSF) pleocytosis (white blood cell count > 5/µL
Abnormal neuroimaging findings consistent with encephalitis and/or abnormal electroencephalogram (EEG) reading consistent with encephalitis

HOW DO WE DIAGNOSE ENCEPHALITIS?

Level of suspicion based on history, signs and symptoms, epidemiologic risk factors, recent travel, recreational, occupational exposures, insect or animal contact, seasonality, mood/behavior or personality change resembling acute psychosis
Herpes Simplex Virus: HSV is the most common cause of pediatric encephalitis and should be suspected in any child with concern of encephalitis. Ophthalmologic exam and conjunctival HSV culture to evaluate for eye involvement
Lab Studies: CBC with differential, CMP, HSV serum PCR, Enterovirus serum PCR
Lumbar Puncture/CSF Studies: Cell count, Protein, Glucose, Gram-stain and bacterial culture, HSV PCR, Enterovirus PCR. If patient is not improving, Autoimmune panel, Meningoencephalitis multiplex PCR panel, CSF immunoglobulin M to look for specific arboviruses such as West Nile virus and La Crosse virus, Extra CSF to freeze for additional testing (Obtain opening pressure with lumbar puncture. If there is concern for increased intracranial pressure, always obtain a head CT prior to performing a lumbar puncture
NeuroImaging:
1. MRI with and without contrast. First-line imaging test for pediatric patients with suspected intracranial infection.
2. Dedicated Epilepsy Protocol MRI with and without IV contrast for suspicion of autoimmune encephalitis
3. Computed Tomography (CT): Head CT without IV contrast is first line imaging in pediatric patients presenting with acute mental status change as this can quickly and accurately exclude neurosurgical emergencies
4. Abdominal/Pelvic Ultrasound: Anti-NMDAR encephalitis has ha an association with ovarian teratomas. US may allow resection of the tumor to alleviate the encephalitis
5. EEG: Controversial. Most patients with encephalitis will have an abnormal EEG. Recommend consultation with Pediatric Neurology

“Encephalitis in Previously Healthy Children.” Pediatrics in Review, vol. 42, no. 2, Feb 2021, pp. 68–77.

TREATMENT

HSV is the leading cause of severe encephalitis and is associated with poor outcomes. Acyclovir should be initiated on all patients with suspected encephalitis until HSV is ruled out
Empirical antibacterial antibiotics, while awaiting culture results, focused primarily on coverage for Streptococcus pneumoniae, haemophilus influenzae serotype b, Neisseria meningitidis, Listeria monocytogenes, Mycoplasma
Corticosteroids – more commonly used for viral encephalitis such as varicella zoster and HSV if concern for swelling in the brain
Immunomodulators (help to “calm” the immune system) – Corticosteroids, IVIG (decreases the overall burden of the offending autoantibody), Plasma exchange (potentially removes the disease causing antibodies), Rituximab
Always evaluate for and treat any underlying disease process

PROGNOSIS

Highly variable. Dependent on etiologic agent/cause
Meta-analysis examining outcomes in patients with infectious encephalitis: 42% incomplete recovery, 6.7% severe sequelae, 17.5% decrease in intelligence quotient
HSV encephalitis: Up to 64% experience late effects such as developmental delay, neuropsychological dysfunction, and focal motor deficits
Autoimmune encephalitis: ~ 1/3 demonstrate full recovery, 1/3 partial recovery, 1/3 with limited recovery and severe deficits
Use of immunotherapy in autoimmune encephalitis correlates with improved outcomes

Abdominal Pain Part V: Acute Pancreatitis

PME-Admin article, medical abdominal pain, acute pancreatitis, children, infants, pancreatitis, pediatric, pediatrics

Abdominal Pain Part V: Acute Pancreatitis
Santa J. Bartholomew MD & Cynthia D. Read, LNC

Acute pancreatitis is one of the leading gastrointestinal causes of hospitalizations in the United States, and is increasingly being diagnosed in children within the past two decades.

Characterized by an acute inflammation of the pancreas, older children often present with a sudden onset of persistent, severe mid-abdominal pain that may radiate to the back. Younger children and infants may present with more generalized abdominal discomfort, irritability and vomiting.

The Pancreas

The pancreas is in the abdomen just behind the stomach. The pancreas makes enzymes during digestion that break down sugars, fats and starches. Hormones produced in the pancreas help the digestive system.

Classification

Pancreatitis in children may be mild, moderate, or severe. More severe episodes of pancreatitis typically have more complications. Acute pancreatitis may progress to acute recurring pancreatitis (ARP) or chronic pancreatitis (CP).

TABLE 1: DEFINITIONS OF PANCREATITIS IN CHILDREN (INSPPIRE Criteria)

Etiology

Genetic: <10% in acute pancreatitis, >50% in reoccurring pancreatitis, ~75% in chronic pancreatitis
Anomalies of the pancreas: ~ 5-20% of children with acute pancreatitis
Gallstones: most common cause in children. 3-30% of cases
Medications: contribute up to one-fourth of cases
Trauma: accidents and non-accidental trauma from child abuse
Metabolic Disorders: high calcium levels most common in children. Inborn errors of metabolism
Infection: mumps, herpes, salmonella
Other illness: Lupus, Kawasaki disease, inflammatory bowel disease

Diagnosis

Acute pancreatitis is diagnosed based on the patient’s history, physical exam, and supported by laboratory tests and imaging as indicated. Physical findings on exam will vary based on the severity of disease.

Diagnosis requires two of the following three criteria:

Sudden onset of severe mid-abdominal pain that does not go away. This pain may radiate to the back.
Increase in enzymes made by the pancreas more than three times their normal level
Findings specific to pancreatitis on an ultrasound of the stomach, computed tomography (CT) of the stomach or magnetic resonance imaging (MRI) of the stomach

Classic Examination Findings

Tenderness to mid-abdomen, abdominal distention, yellowing of the eyes, fever
3% of patients with acute pancreatitis may have a bluish discoloration around their umbilicus (Cullen’s sign) or a bluish discoloration along their flank (Grey Turner’s Sign)
Some patients may experience:
- Shortness of breath because the diaphragm just above the pancreas gets inflamed and this may progress to acute respiratory failure.
- 5% of children have hemodynamic instability and end organ failure such as renal failure and shock.

DIFFERENTIAL DIAGNOSIS OF PANCREATITIS

Peptic Ulcer Disease (PUD)
Gallstones
Cholecystitis
Perforated viscus
Intestinal obstruction
Mesenteric Ischemia
Hepatitis

Acute pancreatitis is diagnosed based on the patient’s history, physical exam, and supported by laboratory tests and imaging as indicated.

LABORATORY SIGNS

Elevated amylase and lipase: these are enzymes secreted by the pancreas.
- Lipase: elevations are highly sensitive for pancreatitis (85-100%) and rise within 4-6 hours of the onset of symptoms and generally return to normal within 8 to 14 days
- Amylase: elevations with 6 to 12 hours but usually returns to normal within 3-5 days. Serum amylase > three times upper limit of normal has 67 to 83% sensitivity for acute pancreatitis.
- The “gold standard” for diagnosis of acute pancreatitis: elevated lipase and amylase
Markers of immune activation:
- Increase C-reactive protein
- Increase procalcitonin.
- Increase TNF
- Elevated white count
Signs of third spacing
- Elevated hematocrit from hemoconcentration
- Elevated BUN and creatinine
Hyperglycemia/hypoglycemia: with broad swings in insulin levels- insulin also being a hormone secreted by pancreas.

IMAGING

X-ray of abdomen may show distention of bowel/intestines
Abdominal Ultrasound- First choice of imaging in pediatrics
Abdominal CT- is not needed to diagnose pancreatitis
Magnetic resonance cholangiopancreatography (MRCP) – a special kind of MRI used to look at the pancreas and the organs around the pancreas. Is quickly becoming study of choice in pediatrics

Ultrasound of a Human Pancreas

MANAGEMENT AND TREATMENT

Supportive care with fluids, pain control, and nutrition.
Change in therapy in recent years has been towards feeding through the acute phase of pancreatitis.
If unable to take fluids and medications by mouth, may require hospitalization for IV fluids and nutrition through a feeding tube or an IV.
Treat any underlying diseases or predisposing factors for pancreatitis.
If there is an obstruction to flow of secretions from pancreas, then ERCP (endoscopic retrograde cholangiopancreatography) may be needed. While it is not as commonly used in children as in adults has become an invaluable tool in helping treat obstruction.
Islet auto-transplantation (TPIAT) has become the surgery of choice for recurring pancreatitis and chronic pancreatitis. This entails all or part of the pancreas is removed, and special insulin producing cells being placed in the liver as an alternative.

Nguyen,T. (n.d.). Pancreatitis [Review of Pancreatitis]. 41(10).

COMPLICATIONS AND PROGNOSIS

Most children presenting with acute pancreatitis will have mild pancreatitis. Complications that may occur from pancreatitis range from mild to more severe including:

Infection
Fluid collection around the pancreas
Pancreatic Pseudocyst: encapsulated collection of necrotic tissue, secretions or blood
Pancreatic Necrosis: an area of tissue in the pancreas dies due to too little blood supply

The mortality rate for acute pancreatitis in children is <5%. In ~ 15-35%, their pancreatitis will reoccur. Children with acute reoccurring pancreatitis and chronic pancreatitis tend to have more genetic and/or anatomical risk factors compared to adults who tend to have more environmental risk factors. In adolescents, autoimmune and environmental risk factors begin to emerge.

Abdominal Pain Part IV: Inflammatory Bowel Disease and Ulcerative Colitis
Santa J. Bartholomew M.D.

The category of inflammatory bowel disease (IBD) is divided into two specific categories: Crohn’s disease and Ulcerative colitis, both of which are diagnosed in late childhood or early adulthood. IBD is one of the major chronic gastrointestinal diseases among children and adolescents in the westernized world.

Both are characterized by a chronic and debilitating condition defined by a relapsing episode of GI inflammation. In Ulcerative colitis (UC), this includes the superficial lining of the bowel starting at the rectum, and it is limited to the colon. In Crohn’s disease (CD), the inflammation can affect any part of the GI tract from mouth to colon, and it is transmural (across the entire bowel wall).
Pediatric patients often have more severe disease of both UC and CD than their adult counterparts.
In children, there is a male predominance
25% of IBD occurs in childhood, the rest in early adulthood, with the worst of the disease peaking in the second and third decades of life.
- Incidence: Crohn’s Disease: 40/100,000 and Ulcerative Colitis
- Approximately 1.4 million people suffer from IBD in the USA
- A subset of children acquire IBD at a very early age and this is thought to be a different type of IBD than what is seen in older children.

What is the cause of IBD?

The cause of IBD is unknown, but there are several theories:

Dysregulation of the hosts immune system to the normal bacteria that live in the bowel
Genetic component
Alterations in the bacterial biome of the gut
Environmental exposures- since IBD is a Western world disease, it seems reasonable that our diet and food hygiene may play a role in the development of IBD.

Symptoms of IBD

Presenting symptoms: can be HIGHLY VARIABLE.

Abdominal pain: varying quality and location.
Nausea and vomiting
Rectal bleeding
Diarrhea
Weight loss
Growth delay

Pediatric patients often have more severe disease of both UC and CD than their adult counterparts.

Albumin can be low because of poor nutritional health
Chronic inflammation of the bowel can lead to malabsorption, so vitamin and Zinc levels may be low
There can be other organs affected, such as the liver, and then one would see elevated transaminases

Other organs affected:

COMORBID SIGNS AND SYMPTOMS OF INFLAMMATORY BOWEL DISEASE BY ORGAN SYSTEM

Peds in Review:37(8) Aug 2018

Diagnosis:

Children suspected of IBD need a referral to a GI specialist
Endoscopic examination and biopsies help confirm the diagnosis and determine UC from CD
One-third of patients cannot be classified into either category as there is inflammation of the ileum.

During an upper endoscopy, a thin flexible tube with a camera on the end is inserted into the mouth and down the esophagus to look at the esophagus, stomach, and duodenum.

Treatment for IBD

Treatment involves controlling active symptoms and trying to prevent long-term complications. Treatment, however, is complicated as many of the therapies can impact the growth of the child.

STEROIDS: help induce remission in both UC and CD, but fewer than a third of patients achieve true healing of the bowel mucosa so it can go back to normal function
ENTERAL NUTRITION: giving 100% of the nutritional needs of the child as a liquid diet is also used to induce remission and help heal the mucosa
AMINOSALICYLATES: are topical anti-inflammatory drugs that help decrease inflammation in the bowel, such as Sulfasalazine
IMMUNOMODULATORS: Also assist in attaining and maintaining remission but come with significant side effects such as myelosuppression, chemical hepatitis, pancreatitis, and in a small number of cases lymphoma
ANTI-TNF THERAPY: biologics such as Infliximab, Adalimumab, and Golimumaub that are used to induce remission in children resistant to steroids or who are steroid dependent despite using an immunomodulator. The can, however, cause a psoriasis-like rash, and increased risk of infection, particularly fungal, viral, and mycobacterial infections
SURGERY: total colectomy with an ileal pouch is used in children refractory to medical therapy

Long-term problems:

Growth failure in 40% with CD and 10% with UC
Vitamin deficiencies: Iron, Folate, Vitamin B12, and Vitamin D
Colon cancer
Depression and anxiety disorders

Periodic Breathing in Infants

PME-Admin article, medical apnea, breathing, breathing issues, children, pediatric, pediatrics, periodic breathing

Periodic Breathing in Infants – Santa J. Bartholomew M.D.

What is Periodic Breathing in Infants?

Periodic breathing is a normal condition that affects healthy moderately preterm infants. It is characterized by periods of irregular breathing in which the infant breathes rapidly for several cycles then has a 5 to 10 second pause in breathing, only to repeat the cycle again.

Periodic breathing usually occurs during sleep and is often seen in premature babies, although it can happen in term infants it is quite rare.

How is periodic breathing different from apnea?

Apnea is a developmental disorder that reflects physiologic immaturity on the part of an infant in which breathing stops for more than 20 seconds. Apnea can be caused by many things, including respiratory infections, heart problems, reflux and most commonly prematurity. Unlike periodic breathing, apnea can be life-threatening and requires immediate medical attention.

In this blog post, we’ll discuss how to diagnose periodic breathing in infants, as well as what you should do if your child exhibits symptoms.

Unlike periodic breathing, apnea can be life-threatening and requires immediate medical attention.

Signs and Symptoms of Periodic Breathing in Infants

The most common symptom of periodic breathing is periods of irregular breathing during sleep. Other signs and symptoms include:

Crying or grunting during periods of irregular breathing
Stopping breathing for 5-10 seconds followed by deep sighing or gasping and repeat of the breathing pattern.

Signs and Symptoms of Apnea in Infants

Apnea can become evident in preterm infants in the first two or three days of life who are breathing unassisted from support.

There are periods of 15+ seconds or more of not breathing.
There may be color change: bluish lips
The heart rate in the infant may slow down

Treatment for Periodic Breathing in Infants

Most healthy babies outgrow periodic breathing on their own within a few months. As such, treatment is typically not necessary. Simply following guidance for safe sleeping, such as lying your infant on his/her back, can often alleviate symptoms.

When should you seek medical attention?

Parents should call 911 if a child exhibits more serious symptoms and is in need of emergency help. Examples of times when it may be necessary to contact 911 include:

Child stops breathing, their skin turns blue, or they become unconscious
Child experiences severe trouble breathing with chest sinking in, using their belly muscles to breathe, or their nostrils begin flaring during an episode of difficult breathing.
In severe cases, it may be necessary for you to proactively administer rescue breathing and follow any instructions provided by emergency providers while you wait for assistance to arrive.

Final thoughts on periodic breathing in infants

If you think your infant may be experiencing periodic breathing, it’s important to talk to your healthcare provider. They will be able to properly diagnose the condition and recommend treatment options that are best for your child. Most healthy babies outgrow periodic breathing on their own, but there are some actions parents and providers can take that can help alleviate the symptoms in the meantime. With proper care, infants will be back to regular breathing in no time.

Pneumonia in Children – Symptoms, Diagnosis, and Treatment
Santa J. Bartholomew M.D.

Pneumonia is a form of lung inflammation that can cause serious respiratory illness, and can be especially life-threatening in children. Symptoms of pneumonia range from mild to severe, and the condition can be fatal in some cases. Early diagnosis and treatment of pneumonia is essential for easy recovery. In this blog post, we will discuss the symptoms, diagnosis, and treatment of pneumonia in children.

Symptoms and Diagnosis of Pneumonia

The main symptoms of pneumonia in children include:

Coughing up mucus
Rapid breathing or difficulty breathing
Chest pain when coughing or breathing
Fatigue or exercise intolerance
Fever, excessive sweating, or chills
Loss of appetite
Nausea, vomiting, or diarrhea
Bluish tint to lips or nails

How to Treat Pneumonia in Children

Treatment for pneumonia in children usually involves antibiotics and rest. In severe cases, hospitalization may be necessary. With early diagnosis and treatment, most children recover from pneumonia without any complications.

Pneumonia Prevention

To prevent pneumonia in children, it is important to practice good hygiene habits such as washing hands frequently and avoiding close contact with people who are sick. It is also important to make sure your child is up-to-date on their vaccinations, as some types of pneumonia can be prevented with vaccination. If your child is showing signs or symptoms of pneumonia, it is important to call a doctor right away. Early diagnosis and treatment are essential for a child’s recovery from pneumonia.

Monkeypox and the Impact of Pediatric Infections

PME-Admin article, medical children, infections, monkeypox, pediatric, pediatrics

Monkeypox and the Impact of Pediatric Infections — Santa J. Bartholomew M.D.

Monkeypox and the Impact of Pediatric Infections

Monkeypox is a rare viral disease that is similar to human smallpox. Prior to 2021, the last outbreak of monkeypox in the United States occurred in 2003, when there were 47 confirmed and probable cases. However, the majority of these cases were imported from Africa, where the disease is more common.

The first known outbreak of monkeypox occurred in 1958 in the Democratic Republic of Congo. This outbreak was confined to monkeys, while the first documented human case of Monkeypox was not discovered until 1970.

Since then, there have been sporadic outbreaks of the disease in Africa. The largest outbreak of monkeypox occurred in 1996-1997 in the Congo Basin region. During that outbreak, more than 500 people were infected and 37 people died.

Studies have shown that children under the age of five are three times more likely to die from monkeypox than adults.

What is Monkeypox?

Monkeypox is caused by a virus from the Orthopoxvirus genus. This family of viruses includes variola virus, which causes smallpox, and vaccinia virus, which is used in the smallpox vaccine. There are two different strains of monkeypox virus: West African monkeypox and Central African monkeypox. Central African monkeypox is more severe and has a higher fatality rate.

How Does Monkeypox Spread?

Monkeypox can be spread through contact with an infected animal, such as a monkey, rat, or squirrel. It can also be spread through contact with infected material from these animals, such as their blood or skin. The disease can also spread from person to person through close contact with an infected individual, such as touching or kissing them.

How Does Monkeypox Impact Children?

Children are particularly susceptible to monkeypox infections. In fact, studies have shown that children under the age of five are three times more likely to die from monkeypox than adults. Monkeypox can be deadly in some cases, but with prompt medical treatment, patients have a good chance of recovery.

Recent Pediatric Monkeypox Infections and the Impact on Children

There have been several outbreaks of monkeypox in Africa over the past few years. Children have been adversely affected by these outbreaks. During a 9-month period in 2020, for example, 42% of those affected by the virus were children.

What is concerning is that the case fatality ratio during this period for children under 5 years of age was 4.2%, which was a 0.8% increase from those over the age of five.

In the United States, there have been 22,630 reported cases as of the publication of this article. California (4,300) and New York (3,679) exhibited the highest number of cases, with Florida (2,282), Texas (2,017), and Georgia (1,607) rounding out the top five states.

Children under 15 years of age were largely not impacted by the recent infections. The largest demographic impacted by Monkeypox in the US has statistically been men aged 31-35 years of age.

Conclusion

Although it is rare, monkeypox can be a serious illness, especially in young children. The best way to protect yourself from this disease is to avoid contact with animals that may be carrying the virus. Wash your hands thoroughly if you come into contact with an infected animal. If you think you may have been exposed to monkeypox, please seek medical attention immediately.
