In a retrospective study, we review here the clinical presentation of patients with the biphasic form of hepatitis A, a variant of viral hepatitis characterised by an increase in ALAT levels after an initial recovery in clinical condition and laboratory tests. Twenty-one patients were diagnosed as having a biphasic form; they represent about 10% of a(More)
Function of the wrist and hand in lower root avulsions is severely impaired. Based on anatomic and experimental studies which suggest that the motor nerve of the brachialis muscle could be used as a selective neurotizator in lower root avulsions with intact C5-C6 +/- C7 roots (Klumpke paralysis), we considered its use depending on the target. We describe(More)
The long-term hemodynamic and renal effects of propranolol were compared with those of propranolol plus isosorbide dinitrate in 44 portal-hypertensive alcoholic cirrhotic patients. Eight control patients, 8 patients receiving propranolol and 14 patients receiving propranolol plus isosorbide dinitrate were hemodynamically evaluated. Renal function was(More)
156 patients with chronic hepatitis were studied in Rosario, Argentina. 98 patients were HBsAg positive (group I) and 58 patients were negative (group II). 209 normal volunteer blood donors served as controls (group III). In all cases the presence of anti-HAV was sought by RIA and was found in 92% of cases in group I, 91% in group II and 82% in group II(More)
The conjugated cholic acid (glycocholic acid) (GC) in the serum and the conjugated sulfolithocholic acid (sulfolithoglycocholic acid (SLGC) in 35 aggressive chronic hepatitis (HCA), 22 cirrhosis, 11 primary biliary cirrhosis (CBP), 11 pruritus of pregnancy and in 20 normal controls were determined. The control group revealed a mean value of GC of 21(More)
Extrahepatic and intrahepatic biliary obstruction of different etiology were studied in 62 patients, who were investigated for the presence of lipoprotein X (Lp-X). It was found present in 19 of 20 cholestasis by lithiasis, in all three primary biliary cirrhosis patients, in 2 of 4 cirrhosis, in 5 of 13 hepatitis, in all three benign recurrent intrahepatic(More)
Seventy-seven consecutive HBeAg-positive chronic hepatitis patients were studied from 1971 to 1983 to establish the seroconversion rate in the e system. Patients with less than a year of follow-up were not included in the study. Fifty-six patients with chronic active hepatitis (CAH) received immunosuppressive treatment (corticosteroids combined with(More)
Sera of 155 chronic hepatitis (CH) patients in Argentina were tested for the presence of HBsAg, anti-HBs, anti-HBc, and anti-HAV. Our purpose was to define the role that both virus A and B might play in the etiology and pathogenesis of this condition. The patients were divided into two groups: group I (57) HBsAg-negative; group II (98) HBsAg-positive. The(More)
