Case ReportsOral Mucosal Envenomation of an Infant by a Puss Caterpillar.
The term "puss caterpillar" describes the larva of at least two Megalopygidae species common to North America. Accidental contact with the hairs (setae) is intensely painful, and serious systemic effects have been reported. We describe the envenomation of an infant through the face and oral mucosa, resulting in severe discomfort, limited oral intake, and vomiting, but no other untoward effects.

Review Case ReportsCatecholaminergic Polymorphic Ventricular Tachycardia.
Catecholaminergic polymorphic ventricular tachycardia is a rare cause of exercise-induced arrhythmia and sudden cardiac death in the pediatric patient. This arrhythmia is difficult to diagnose in the emergency department, given the range of presentations; thus, a familiarity with and high index of suspicion for this pathology are crucial. Furthermore, recognition of the characteristic electrocardiogram findings and knowledge of the management of the symptomatic patient are necessary, given the risk of arrhythmia recurrence and cardiac arrest. In this review, we discuss the presentation, differential diagnosis, and management of catecholaminergic polymorphic ventricular tachycardia for the emergency care provider.

Review Case ReportsAcute Focal Bacterial Nephritis Associated With Central Nervous System Manifestations: A Report of 2 Cases and Review of the Literature.
Acute focal bacterial nephritis (AFBN) is a localized bacterial infection of the kidney presenting as an inflammatory mass without frank abscess formation. In children, most patients with AFBN present with nonspecific conditions, such as fever, vomiting, and abdominal pain. ⋯ The first case was a 3-year-old girl who had neurological symptoms, including unconsciousness and seizures, with AFBN associated with acute reversible encephalopathy. The second case was a 5-year-old girl who had neurological symptoms, including unconsciousness, with AFBN accompanied by clinically mild encephalitis/encephalopathy with a reversible splenial lesion.

Case ReportsSevere Neck and Face Edema in an Adolescent-Delayed Hypersensitivity Reaction to Hair Dye.
Allergic contact reactions to hair dyes arise mostly due to sensitization to para-phenylenediamine (PPD). Para-phenylenediamine, a derivative of p-nitroanaline, is widely used as an oxydizable hair dye and is also found in black henna tattoo. ⋯ Here, a 15-year-old girl is presented, who developed a hypersensitivity reaction after first exposure to hair dye. She was found to have been sensitized to PPD before, through application of black henna tatto.
