It is increasingly recognized that osteoporosis affects children as well as adults both as a primary problem and as secondary to various diseases, medications, and lifestyle issues. In this review, we emphasize the correct diagnosis of osteoporosis in children as opposed to adults, etiology, and pharmaceutical and non-pharmaceutical treatments. We especially focus on rheumatologic conditions associated with osteoporosis and management issues.

Subcutaneous fat necrosis (SCFN) of the newborn is an uncommon dermatologic disorder characterized by firm, palpable subcutaneous nodules or plaques with or without erythema. Despite its benign course, SCFN may become complicated by extracutaneous manifestations. Hypercalcemia is considered a rare complication, but it is potentially fatal if unrecognized. During the last several years therapeutic hypothermia (TH) became an essential new therapeutic modality for severe neonatal asphyxia. We report a neonate who presented with SCFN and hypercalcemia following hypothermia therapy for hypoxic ischemic encephalopathy (HIE) and provide a review of the contemporary literature on the topic. We believe that this is important since the use of TH is rapidly increasing, and therefore, the possible side effects including SCFN and hypercalcemia may also become more prevalent. This prompts the need for awareness by treating physicians for this complication.

Gastroenteritis-related seizures have increasingly gained attention in recent years. Most cases follow a brief, benign course with very few episodes of seizure recurrence and without development of epilepsy. Published reports usually do not make a distinction between febrile and afebrile patients, and most authors include only nonfebrile convulsions in their reported series. This study evaluated the impact of fever in children presenting with seizures during a mild gastroenteritis episode and found that the presence or absence of fever did not affect seizure characteristics or duration. However, mild hyponatremia affected some seizure features, particularly seizure duration, as hyponatremic children sustained more prolonged seizures than patients with normal serum sodium levels, irrespective of body temperature.
