Review Case Reports
Kikuchi-Fujimoto disease: a rare but important cause of lymphadenopathy.
Cervical lymphadenopathy is a common problem in children. Kikuchi-Fujimoto disease (histiocytic necrotizing lymphadenitis) is a rare condition that causes persistent lymphadenopathy and has a characteristic histological appearance. Kikuchi-Fujimoto disease is well recognized in Japan, where it was first described, but descriptions in the paediatric literature are sparse. Paediatricians may therefore be unaware of this rare but important condition. The case is described of a 14-y-old girl suffering from fatigue, weight loss, night sweats and lymphadenopathy. The predominance of systemic symptoms prompted an extensive investigation. The diagnosis of Kikuchi-Fujimoto disease was made after direct histological examination of a lymph node biopsy. The case illustrates the clinical features of this little-known condition and highlights the potential confusion with other diagnoses. The pathological features are discussed and the literature reviewed. ⋯ Kikuchi-Fujimoto disease should be considered in cases of persistent lymphadenopathy. An early biopsy can be instrumental in preventing unnecessary investigations and potentially harmful treatments.

To determine the relation between the level of initial neonatal care and in-hospital mortality of infants born before 33 wk of gestation in the era of surfactant therapy. ⋯ In-hospital mortality in non-teaching level III units was similar to that in a teaching unit, but significantly higher in level I-level II units. Neonatal care of newborns delivered before 33 wk of gestation should initially occur in level III units.

Comparative Study
Effect of perinatal asphyxia on thyroid-stimulating hormone and thyroid hormone levels.
To compare serum concentrations of thyroid hormones--T4, T3, free T4 (FT4) and reverse T3 (rT3)--and thyroid-stimulating hormone (TSH) found in the umbilical cord blood of term newborns with and without asphyxia and those found in their arterial blood collected between 18 and 24 h after birth. A further aim of the study was to assess the association between severity of hypoxic-ischemic encephalopathy and altered thyroid hormone and TSH levels, and between mortality and FT4 levels in the arterial blood of newborns between 18 and 24 h of life. ⋯ Serum concentrations of TSH, T4, T3 and FT4 are lower in asphyxiated newborns than in normal newborns between 18 and 24 h of life; this suggests central hypothyroidism secondary to asphyxia. Asphyxiated newborns with moderate/severe hypoxic-ischemic encephalopathy present a greater involvement of the thyroid function and consequently a greater risk of death.
