From 1978 to 1989, 4,772 endoscopic cytological examinations of the stomach have been done in our laboratory, including 903 patients with a final diagnosis of gastric carcinoma. There were seven false-positive results among 3,810 examinations done in patients without malignant disease (specificity 99.8%). Cytology yielded positive results in 785 of 903(More)
The usefulness of second-look laparoscopy in the follow-up of ovarian cancer is evaluated. This procedure has been included in the protocol for the treatment of these tumors. During the period 1980-1987 a total of 3038 laparoscopies were performed; 205 (7%) were for ovarian cancer. We present the results of 72 explorations in 52 patients; after surgery and(More)
BACKGROUND The risk of hepatitis B virus infections is high among alcohol abusers, and vaccination has been evaluated in previous studies. However, the response has been low with the usual doses and schedules. METHODS In the present controlled trail a group of 14 alcohol abusers was vaccinated following a rapid schedule with a dose twice the usual one.(More)
Cirrhotic patients with ascites and low levels of ascitic fluid C3 and total protein and cirrhotic patients with gastrointestinal hemorrhage are at high risk of infection. Selective intestinal decontamination with oral norfloxacin is useful to decrease the incidence of infections in cirrhotic patients at high risk. This study analyzes hospital acquired(More)
INTRODUCTION Pregnancy produces multiple changes in the mother's body, most of which have been studied. However, changes in hepatosplenic circulation are not well-known. The routine use of ultrasonography and of echo-Doppler has created new possibilities for the knowledge of splenic circulation during pregnancy. MATERIAL AND METHOD We studied 30 healthy(More)
Selective intestinal decontamination for 7 days with norfloxacin was performed in 14 cirrhotic patients with ascites and low ascitic fluid total protein. Variations in serum and ascitic fluid of C3 and C4 and ascitic fluid total protein after therapy were compared with those of a control group of 14 untreated patients with similar characteristics. After(More)
In 1985 Ogasahara observed that treatment with ubiquinone produced improvement in the cardiac conduction and the metabolism of the lactic and pyruvic acids in the Kearns-Sayre syndrome. The results of the administration of 150 mg/day of ubiquinone for 3 years in a patient diagnosed with the Kearns-Sayre syndrome is described. The patient improved notably in(More)
A prospective randomized trial involving 64 patients with bleeding peptic ulcers was performed to assess the efficacy of two modalities of injection therapy. The inclusion criterion was the presence of active bleeding or a visible vessel at emergency endoscopy. Thirty-two patients were treated with epinephrine (Group A) and 32 with epinephrine plus thrombin(More)
Liver disease is a well-known cause of early morbidity and mortality affecting 80% of patients receiving allogeneic bone-marrow transplantation (BMT). Drug toxicity, veno-occlusive disease (VOD), acute graft-versus-host disease (GVHD), and fungal, bacterial, and viral infections are the most frequent hepatic complications during this period. The aim of this(More)
