We report a case of calcinosis cutis following administration of 10% calcium gluconate, used for the treatment of a hypocalcemic seizure in a 5-week-old neonate. After administration of 10% calcium gluconate, subcutaneous induration developed at the infusion site. The histopathological findings taken from the dorsum of the left foot showed multiple foci of calcium deposits with infiltration of epitheloid histiocytes between collagen bundles and foreign body giant cells phagocyting calcific granules throughout the reticular dermis and subcutis.

Minoxidil is a potent direct-acting peripheral vasodilator indicated in the management of severe or refractory hypertension. Well-known adverse effects include reflex tachycardia, fluid retention and hypertrichosis. This drug has also been reported to cause pericardial effusion in about three percent of nondialyzed patients with compromised renal function and to cause cardiac tamponade less frequently. Many studies have reported that the mean duration of therapy that caused pericardial effusion was about 8 months (range 1 month-53 months). We report a case of cardiac tamponade in nondialyzed patient with chronic renal failure receiving minoxidil for 10 years. A 58-year-old female was admitted to our hospital with dyspnea of NYHA III. She was a chronic renal failure patient without dialysis treatment and received kidney transplantation from cadaver donor and was dignosed chronic rejection in 1994. Minoxidil 10mg has been used for past 10 years. Lasix has been used for past 2 years, with dosage of 40mg to 240mg. On admission, blood pressure was 90/60mm Hg. Cardiomegaly was seen on chest radiograph. The two-dimensional echocardiogram showed a large amount of pericardial effusion. Emergency treatment with pericardiocentesis removed 2500ml of straw- colored pericardial fluid and resulted in marked improvement of dyspnea and stabilized blood pressure. The minoxidil was discontinued. The evidence of pericardial effusion was not seen for 12 months after minoxidil had been discontinued.

This study was carried out to investigate the mechanisms of acinar cell deletion, leading to the pancreatic atrophy of rat pancreas after experimental duct ligation. Fifty-seven male Sprague-Dawley rats, maintained on a stock diet, weighing 200 gm, in average, were divided into 2 experimental groups. Group 1. Control group. Six rats. Abdominal cavity was opened and closed without further treatment. Group 2. Fifty-one rats. Animals were treated with partial ligation of the pancratic ducts according to the procedure developed by Hultquist followed by sequential sacrifices at: 1 hour (3 rats), 3 hours (3 rats), 6 hours (6 rast), 12 hours (3 rats) and 24 hours (8 rats); 2 days (8 rats), 3 days (3 rats), 4 days (3 rats) and 5 days (5 rats); 1 week (3 rats), 2 weeks (3 rats) and 8 weeks (3 rats); after partial ligation was extirpated and examined by both light and electron microscopy. The results obtained were as follows: Light microscopically, noted were an interstitial edema and focal necrosis of the pancreatic tissue along with fine vacuolization and depletion of the zymogen granules in the acinar cell cytoplasms and condensation of the acinar cell nucleus. These changes were observed by 2 days after ligation. At about the same time, one can observe the dense body, identified to be apoptotic body, in the acinar cell which were found to be decreased in quantity. By 5 days after ligation, no recognizable acinar cells left in the collagenous stroma except intercalated ducts. Conspicuous stroma except intercalated ducts. Conspicuous stromal hyalinization, thereafter. Electron microscopically (TEM and SEM), nuclear condensation and margination toward the nuclear membrane was noted by 6 hours after duct ligation. By 24 hors sporadic membrane-bounded apoptotic bodies appeared in the acinar cells, the number of which reaching to the peak by 3 days after ligation. These apoptotic bodies were found to be phagocytosed by either intraepithelial mononuclear phagocytes or adjoining acinar cells. It can be concluded, therefore: That orderly remodeling of pancreatic exocrine tissue during atrophy is effected by rapid deletion of acinar cells by apoptosis.
