Multiple facial hemangiomas and iron-deficiency anemia: blue rubber-bleb nevus syndrome.

A 21-year-old female complained of bluish soft tumors on her face. Her past history of anemia led us to investigate a possibility of "Blue Rubber-Bleb Nevus syndrome." Subsequent examinations revealed a severe iron-deficiency anemia and gastrointestinal tract hemangiomas. The facial hemangiomas were removed after controlling anemia. It is important to examine the gastrointestinal tract when multiple cutaneous hemangiomas are associated with anemia.

Primary biliary cirrhosis complicated with sigmoid colonic varices: the usefulness of computed tomographic angiography.

Gastroesophageal varices are the major complication of portal hypertension. Ectopic varices develop in various organs such as the duodenum, colon, and gallbladder. However, varices other than at gastroesophageal or rectal sites is a rare entity. We report a 53-year-old patient with primary biliary cirrhosis complicated by sigmoid colonic varices. Computed tomographic angiography was useful to understand the entire status of the varices.

Reconstruction of adactyly for 4th and 5th toes: the study of foot pressure.

Analysis of foot pressures in cases of reconstructed adactyly of the lateral toes is presented. Two cases with adactyly of the 4th and 5th toes in which new toes were created by cross-knee tubed pedicle flap were chosen and foot pressures of both the operated foot and the contralateral normal foot were measured postoperatively. The results did not indicate any functional disturbance after this method of reconstruction.

Urinary N-acetyl-beta-glucosaminidase and guanidinoacetic acid levels in epileptic patients treated with anti-epileptic drugs.

We investigated potential renal functional impairment induced by chronic use of anti-epileptic drugs (AEDs) in 79 epileptic children. They were divided into five groups: valproic acid (VPA) monotherapy where the serum concentration (SC) of VPA was no less than 60 micrograms/ml (VPA [SC > or = 60]) (15 cases), VPA monotherapy where the SC VPA was less than 60 micrograms/ml (VPA [SC < 60]) (29 cases), phenobarbital monotherapy (PB) (7 cases), carbamazepine monotherapy (CBZ) (16 cases), and polytherapy containing VPA (12 cases). Urinalysis (proteinuria and hematuria) and serum creatinine were normal except for two cases of proteinuria and two cases of hematuria. The level of urinary excretion of N-acetyl-beta-glucosaminidase (u-NAG) was high in 29% of all patients, and 47% of VPA (SC > or = 60), 38% of CBZ, 25% of polytherapy, and 24% of VPA (SC < 60) groups. There was a significant positive correlation between serum concentration of VPA and u-NAG/urinary creatinine (u-Cr). The level of guanidinoacetic acid (u-GAA) excreted in the urine was normal except in one patient. U-NAG/u-Cr may be a more sensitive marker than u-GAA/u-Cr for renal functional impairment in AED therapy.

Calcific tendinitis of the gluteus maximus tendon with cortical bone erosion: CT findings.

A case of calcific tendinitis of the gluteus maximus tendon with cortical erosion is presented. Roentgenography demonstrated calcification on the posterior surface of the proximal femur. Computed tomography showed flame-like appearance of calcific tendinitis and bone erosion. Magnetic resonance imaging showed minimal inflammatory reaction around the lesion.

Continuous isoproterenol inhalation therapy in children with severe asthmatic attack.

We studied the 1-type isoproterenol inhalation therapy for patients with severe asthmatic attacks who were admitted at the Department of Allergy of National Children's Hospital from 1981 to 1991. One hour after l-type isoproterenol inhalation therapy, statistically significant effects were noted with regard to the asthmatic status. Moreover, no side effect was found amoung the subjects. From these data, 1-type isoproterenol inhalation therapy is thought to be effective for severe asthmatic attacks.

Milk of calcium renal stone in a patient with acute promyelocytic leukemia.

A case of milk of calcium renal stone is reported. This is a rare disease in which a suspension of calcium salts is formed within a renal cyst. The pathognomonic sign is a fluid level seen in a standing position and an oval density seen in a supine position. In the present case, the milk of calcium was found to develop in a hydronephrotic kidney during the course of acute promyelocytic leukemia and this condition was suggested to be a complication of infection.
