Recurrence of rapidly progressive glomerulonephritis probably associated with two different kinds of drugs

We describe a rare case that developed a rapidly progressive glomerulonephritis twice in a 69-year-old man during a course of treatment, first with allopurinol and then with piperacillin. The cessation of each treatment was followed by spontaneous recovery in renal function. A renal biopsy showed crescentic glomerulonephritis with mild tubulointerstitial change and a skin biopsy showed leukocytoclastic vasculitis. This is, to our knowledge, a very rare case of crescentic glomerulonephritis, probably associated with vasculitis during a course of treatment with two different kinds of drugs.     

Aortocaval fistula with acute right heart failure during surgery: case report

A 71-year-old man was transferred to our institution with suspected of impending rupture of the abdominal aorta. The clinical manifestations included abdominal pain, pulsatile mass, and abdominal bruit. We made on early diagnosis of aortocaval fistula based on enhanced computed tomography and color Doppler flow imaging. Surgical repair was performed 24 hours after the onset of symptoms. At the introduction of anesthesia, cardiac arrest with high central venous pressure occurred. After resuscitation and rapid clamping of the proximal aorta, surgical closure of the fistula with graft replacement was performed successfully.     

Hypogammaglobulinaemia in a patient with ring chromosome 21

An 8 year old boy with ring chromosome 21 who was susceptible to sinorespiratory infections due to hypogammaglobulinaemia is reported. He presented with the characteristic features of monosomy 21 syndrome, such as psychomotor retardation, hypertonia, large saccular ears, prominent nasal bridge, micrognathia, thrombocytopenia, and patent ductus arteriosus. His serum IgG concentration was less than 1.5 g/l at 3 years and 6 months of age after repeated hospitalisations with pneumonia, otitis media, and convulsions. Regular replacement of intravenous gammaglobulin effectively reduced such infectious episodes. A predisposition to infection in patients with ring chromosome 21 may be explained by hypogammaglobulinaemia and merit treatment with gammaglobulin.
