Pancytopenia after intramuscular iron-dextran treatment occurred in an infant with Down's syndrome. Haematological abnormalities recurred on subsequent challenge. Positive migration inhibiting factor and mast cell degranulation tests support an allergic pathogenesis for the pancytopenia. These side effects have not been reported previously.
Three cases of discitis in early childhood presented with acute refusal to walk or change in gait pattern without neurologic deficits. In all three, a Gowers' sign was observed, although none had muscular weakness. The diagnosis of discitis was confirmed by the characteristic radiographic findings on survey lumbosacral films and/or by a hot spot at the L3 level on technetium bone scan.
An infant with microcephaly and generalized cytomegalovirus infection presented with two unusual complications: cystadenoma of the pancreas and minimal change nephrotic syndrome (MCN). Possible pathogenetic mechanisms of these conditions are discussed.
A 12-month-old infant developed bilateral facial paresis 4 weeks following a febrile illness associated with tonsillitis, bronchopneumonia and hepatosplenomegaly. Complement fixing antibody titer to Mycoplasma pneumoniae was 1:128, which subsequently dropped to 1:16. The clinical presentation in our patient was unusual in that he developed bilateral facial palsy at a very young age, and there was also a possible association of the palsy with Mycoplasma infection.

A male infant with multiple congenital anomalies and psychomotor retardation was found to have a translocation resulting in partial trisomy for the distal part of chromosome 3p. An older sister with similar clinical findings had an identical karyotype. Chromosome studies in the phenotypically normal parents revealed a balanced translocation in the mother involving chromosomes 3, 11, and 18. An identical translocation was found in one of the normal children.
A 15-month-old girl initially suspected of having Kawasaki disease is presented. The diagnosis was based on the combination of prolonged fever, conjunctivitis, edema of hands and feet, exanthem and lymphadenopathy. A workup for infectious etiologies was negative. She was subsequently found to have acetaminophen hypersensitivity. To our knowledge this clinical presentation of acetaminophen hypersensitivity has not previously been described in medical literature in English.

Analysis of fifty-two instances of intussusception proved the importance of barium enema examinations as a diagnostic and therapeutic modality. Hypertrophy of the lymphatic tissue in the terminal ileum reactive to common diseases of infancy and childhood is of utmost importance in the etiology of "idiopathic intussusception."

We report an 11-year-old boy with acute rheumatic fever who presented with gastric perforation while treated with corticosteroids (CS). He had been treated initially with acetylsalicylic acid for 11 days, CS replaced the treatment with acetylsalicylic acid due to deterioration of carditis. The possible pathogenesis is discussed.
Sulfasalazine very rarely causes bloody diarrhea. A 3-month-old infant had bloody diarrhea that could be related to sulfasalazine that had been taken by his mother and was transferred through his mother's breast milk. The patient was exclusively breast fed, and no other known etiological factors could be detected for the infant's bloody diarrhea.
