Review Case Reports
The internet, adolescent males, and homemade blowgun darts: a recipe for foreign body aspiration.
We describe our experience with blowgun dart aspiration via an illustrative case series and review the resources available to teach children how to construct these objects. A 15-year-old boy presented with cough, wheeze, and eventually admitted to aspiration of a homemade blowgun dart. This instance heightened the awareness of our experience with blowgun dart aspiration as 3 cases presented within a 3-month period. ⋯ With the accessibility of the Internet and number of instructional websites, this clinical entity may become more common in the future. Unfortunately, only a few of the websites provide any safety warnings. Certainly, prompt treatment can result in good outcomes; however, serious potential complications, including death, could occur especially given the hesitance our patients showed in divulging the truth of the inciting event.

Raised intracranial pressure (ICP) has been proposed as an isolated cause of retinal hemorrhages (RHs) in children with suspected traumatic head injury. We examined the incidence and patterns of RHs associated with increased ICP in children without trauma, measured by lumbar puncture (LP). ⋯ Only a small proportion of children with nontraumatic elevated ICP have RHs. When present, RHs are associated with markedly elevated OP, intraretinal, and invariably located adjacent to a swollen optic disc. This peripapillary pattern is distinct from the multilayered, widespread pattern of RH in abusive head trauma. When RHs are numerous, multilayered, or not near a swollen optic disc (eg, elsewhere in the posterior pole or in the retinal periphery), increased ICP alone is unlikely to be the cause.

We sought to characterize variation in hospital resource utilization and readmission for diabetic ketoacidosis (DKA) across US children's hospitals. ⋯ Readmission for DKA within a year of hospitalization is common. US children's hospitals vary widely in resource use, hospital LOS, and readmission rates for patients with DKA. Our study highlights the need for additional research to understand these differences and to identify the most cost-effective strategies for managing diabetes across the continuum of care.

The objective of this study was to investigate the epidemiology of nonfatal choking on food among US children. ⋯ This is the first nationally representative study to focus solely on nonfatal pediatric food-related choking treated in US EDs over a multiyear period. Improved surveillance, food labeling and redesign, and public education are strategies that can help reduce pediatric choking on food.

Case Reports
Combined pulmonary hypertension and renal thrombotic microangiopathy in cobalamin C deficiency.
Pulmonary arterial hypertension (PAH) and renal thrombotic microangiopathy (rTMA) are rare diseases in childhood, frequently leading to death and end-stage renal disease, respectively. Their combined occurrence has been reported anecdotally. We investigated the clinical, biochemical, and genetic aspects of 5 children with the rare combination of PAH and rTMA. ⋯ One patient had homozygous nonsense mutations of MMACHC. We established cblC deficiency as the denominator in the rare combination of PAH and rTMA in these children. Early recognition of cblC deficiency and vigorous treatment with hydroxocobalamin may beneficially affect the course of this devastating disease.
