If TSH is low, radionuclide scintigraphy is obtained to assess for an autonomous (hyperfunctioning) nodule; these are generally benign and usually do not need biopsy. If TSH is normal or elevated, ultrasound characterization of the nodule and gland follows; referral for ultrasound-guided fine-needle aspiration biopsy is made if the nodule is sonographically suspicious or 1 cm or larger. History is taken specifically asking about prior neck/head irradiation and family history of thyroid disease, medullary thyroid carcinoma, or MEN syndromes, since these change the pretest probability of malignancy substantially. A calcitonin level is checked and RET genetic testing is considered when there is a family history of medullary thyroid carcinoma, pheochromocytoma, hyperparathyroidism, or mucosal neuromas suggestive of MEN-2A or MEN-2B."},

A slower-onset coma, or one preceded by delirium or abnormal behavior, favors a toxic cause over trauma. The classic accidentally-attractive agents — iron tablets resembling candy, and high-ethanol mouthwash without child-safety packaging — are kept in mind when taking an exposure history in a toddler."},

Because ingestions are often unwitnessed, screening is also done for metabolic derangements — hypoglycemia, [[170|hyponatremia]], hyperammonemia — that can accompany or mimic ingestion. The type of exposure is weighed against known risk: caustic ingestion is the leading toxic exposure in children, with most cases from mild alkali agents (bleach, detergents) that can be relatively benign, but button battery ingestion is increasingly common and can be extremely dangerous, and liquid or strong alkali agents cause more severe injury than solids. The classically lethal-in-small-dose pharmaceutical categories are considered specifically — antimalarials, beta-blockers, calcium channel blockers, camphor, antidiarrheals, salicylates, opioids, and tricyclic antidepressants — since these carry disproportionate risk even in small quantities."},

Because up to 60% of children with tinea capitis are asymptomatic carriers, and adult family members can also be asymptomatic carriers who perpetuate reinfection, screening of close contacts is considered when a child has recurrent infection."},
    {"title": "Management", "content": "Topical antifungals alone are not used - they cannot penetrate the hair shaft and will not clear the infection. Oral griseofulvin (first-line) is started for at least 8 weeks in children over 2 years of age, with administration advised alongside fatty food to improve absorption; oral terbinafine for 2-6 weeks is an alternative in children over 4 years. In children under 2 years, oral fluconazole is used; topical azole (e.g., clotrimazole) or allylamine (e.g., terbinafine) therapy is an option in this youngest age group only when the affected hairs are fine. A kerion is managed with the same systemic antifungal therapy - most patients, including those with a boggy, fluctuant-appearing kerion and tender regional adenopathy, respond well to griseofulvin without needing incision or drainage.

In a vaccinated child, breakthrough varicella is kept in mind if the rash looks milder or atypical. The timing of any maternal varicella exposure during pregnancy or around delivery is asked about: infection in the first half of pregnancy (especially 8-20 weeks) raises concern for fetal varicella syndrome (limb hypoplasia, dermatomal skin scarring, eye disease, CNS damage), while maternal varicella from 5 days before to 2 days after delivery risks severe, potentially fatal neonatal disease and needs urgent neonatal assessment."},

Supportive care is adequate for a healthy child; acyclovir/valacyclovir is reserved for adolescents, unvaccinated children 12 years or older, those with chronic skin or lung disease, and immunocompromised children, since these agents shorten disease duration.

Hydrocephalus may be the only sign of congenital toxoplasmosis and typically requires shunt placement regardless of other findings. In an older child or adolescent presenting with visual symptoms, ocular toxoplasmosis is evaluated with T. gondii IgG/IgM serology plus dilated eye examination looking for focal necrotizing retinochoroiditis adjacent to a chorioretinal scar; PCR of aqueous humor can confirm the diagnosis but is rarely needed."},

Because episodes are often missed by the child and family, specific questioning about frequent daydreaming, inattention, or new school performance problems is warranted, since these can be the presenting complaint. If a child presents in a prolonged confused or dreamy state lasting hours, absence status epilepticus is considered and treated with a benzodiazepine."},

Amblyopia - the most common cause of unilateral, preventable, permanent visual impairment in developed countries, affecting up to 5% of the population - is often insidious and will not be caught without systematic vision screening, so parental observation alone is not relied upon to exclude it. If an infant has poor eye contact, fails to fixate and follow, is unresponsive to visual threat, or shows wandering/roving eye movements with a normal eye exam (normal pupillary responses and eye movements on structural exam), cortical visual impairment from perinatal hypoxia, prematurity, hydrocephalus, congenital CNS anomaly, trauma, [[379|intracranial hemorrhage]], or periventricular leukomalacia is considered."},

Acrocyanosis in a newborn is expected in the first 6-24 hours of life (up to 1-2 days, or 24-48 hours with cold stress) and resolves with warming; in an older, normothermic infant, hypovolemia is considered. When a caregiver reports an alarming episode with crying, vomiting, coughing, or breath-holding, a careful history is taken and mental status change is observed for — true acrocyanosis occurs without major mental status change and the child otherwise looks well, whereas seizure, apnea, arrhythmia, or a congenital heart defect need to be excluded when the story or exam does not fit this pattern.

Oral isotretinoin is reserved for the most severe, scarring, or nodular disease at any age.

If a child has a second episode, or any features suggesting genetic risk (family history, PRSS1/SPINK1/CFTR-associated conditions), a structured etiologic work-up is pursued rather than assuming idiopathic disease, since children with PRSS1 mutations in particular can progress to chronic pancreatitis more quickly.

Exacerbations can follow two patterns — a days-long course from progressive inflammation and mucus plugging, versus an abrupt, asphyxial pattern from extreme airway hyperresponsiveness with a very high initial arterial CO2 — so a rapid or recent onset should not be falsely reassuring. High-risk features are identified on history — a prior severe exacerbation, prior ICU admission or intubation, poor controller adherence or inhaler technique, ongoing tobacco/air pollution or allergen exposure, and comorbidities such as obesity, rhinosinusitis, or food allergy — since a prior severe exacerbation is the strongest predictor of a future life-threatening episode."},
