[The estrogen-androgen profile is unchanged in men with cholelithiasis].

It is well established that cholelithiasis is more frequent in women than in men. This difference is usually explained by the effects of estrogens and progesterone on the metabolism of bile acids, biliary cholesterol secretion and saturation, and gallbladder motility. Another explanation could be a protective effect of androgens against cholelithiasis in men. To test this hypothesis, we determined the hormonal, androgenic and estrogenic, status of 15 male patients with asymptomatic gallstone disease and in 15 control patients with normal gallbladder matched for age and body weight. No significant difference in the plasma concentrations and the urinary excretion rate of sex hormones (testosterone, dihydrotestosterone, androstenedione, testosterone and androstanediol glucuronides, estradiol, estrone, total estrogens), as well as in the plasma sex hormone binding globulin, was found between the 2 groups of patients. The development of cholelithiasis in men, therefore, does not appear to be related to modification of sex steroids.

[Increased fasting gallbladder volume: a new ultrasonic sign of cirrhosis?].

Ultrasound was used to calculate fasting gallbladder volume in three groups of patients: 90 with cirrhosis (alcoholic in 75 cases), 41 with non cirrhotic liver disease (alcoholic in 14 cases), and 38 controls. Gallbladder volume was evaluated according to sex, age, alcoholism, presence of gallstones, time of diagnosis, and biological tests of hepatocellular function. Mean fasting gallbladder volume was significantly higher in cirrhotic patients (45.89 +/- 32.65 ml, m +/- 1 SD) than in patients with non cirrhotic liver disease (25.31 +/- 14.08 ml) and in control subjects (21.28 +/- 10.30 ml) (P less than 0.001), but there was a great overlap between individual results in each group. No relationship was found between gallbladder volume and all clinical and biological tested parameters, except for decreased prothrombin time (P less than 0.02). Further studies are necessary to consider this ultrasound sign as an useful diagnostic tool in cirrhosis.

[Cavernous lymphangioma of the liver. A report of 2 cases and review of the literature].

The authors report 2 cases of hepatic lymphangioma observed in a 54-year-old woman, and in a 39-year-old man. These tumors were discovered upon ultrasound examination performed for jaundice due to viral hepatitis, and for abdominal right upper quadrant pain respectively. Computed tomography and angiography showed hypervascularized tumors. Diagnosis was established through surgical biopsy specimens. The clinical course was uneventful, during respectively the 9- and 3-year follow-up periods, respectively. From these and the 40 previously reported cases, the authors describe the different features of this unusual tumor.

"Porcelain liver" appearance due to Glisson's capsule phleboliths.

A case of multiple Glisson's capsule phleboliths is reported in a 29-year-old-woman who had portal vein obstruction with spontaneous shunting resulting in hepatic siderosis and cirrhosis. The phleboliths were visible as multiple linear calcifications on plain film and computed tomography. Diagnosis was established by surgical liver biopsy. The potential mechanisms of this unique entity is discussed.

Gastric bezoar: another side effect of endoscopic variceal sclerotherapy.

Gastric bezoars were observed after esophageal variceal injection of polidocanol in 5 of 56 patients with alcoholic cirrhosis treated by endoscopic sclerosis. We suggest that endoscopic sclerotherapy could have induced a transient vagal injury resulting in delayed gastric emptying and subsequent bezoar formation. Although the volume of sclerosant (25-35 ml per session) and the length of the injector needle (4 mm) were the same in all patients, two reasons could explain the occurrence of bezoars in these five patients: a deeper injection of sclerosant, and a worsening of a preexistent vagal neuropathy due to diabetes mellitus and/or alcoholism.

[Biopsies of the endoscopically normal rectum and colon: a necessity. Incidence of collagen colitis and microscopic colitis].

Collagenous colitis and microscopic colitis are histologic entities which do not have corresponding endoscopic features. Their precise incidence and role in the development of intestinal symptoms are poorly known. The aim of this study was to determine the frequency of these histologic abnormalities in patients with endoscopically normal colon and to correlate these findings with abdominal symptoms. Total colonoscopy was performed in 132 consecutive patients, 81 females and 51 males, aged 19 to 83 years (mean: 47.8 years). Patients complained of abdominal pain and/or diarrhea (66 cases), normal bowel transit or constipation (66 cases). Subjects were prepared for colonoscopy with polyethylene glycol 4,000. Three to 8 biopsies were taken from the rectum and the different parts of the colon. Histologic abnormalities were found in 36 patients (27.2 p. 100): collagenous colitis (7 cases), microscopic colitis (21 cases), and melanosis coli (8 cases). The frequency of diarrhea was significantly higher in patients with collagenous colitis and microscopic colitis than in those with melanosis coli or normal colonic mucosa. These results clearly demonstrate that routine biopsies of the rectum and colon are useful in patients with abdominal symptoms, particularly diarrhea, and normal endoscopy.

[Interobserver and intercenter agreement of gastro-esophageal endoscopic signs in cirrhosis. Results of a prospective multicenter study].

Because of the diagnostic and prognostic value of gastroesophageal endoscopic signs in cirrhosis, we studied their interobserver and intercenter agreement. Fifty cirrhotic patients without previous digestive bleeding were included in this study. The gastroesophageal endoscopic examinations of these patients, recorded on video tape, were independently viewed by 12 observers belonging to different hospitals. Agreement was evaluated by the kappa index (k), the values of which were given with p less than 0.001. Agreement was good for the presence (k = 0.40) or the size (k = 0.51) of esophageal varices as well as for red signs on the mucosa overlying esophageal varices, but it was poor for the color (k = 0.10) or the extent (k = 0.20) of esophageal varices. Agreement was poor for all gastric signs: fundic varices (k = 0.35), red spots (k = 0.28), associated lesions (k = 0.27), mosaic pattern (k = 0.27), gastropathy (k = 0.11). The mean diameter of esophageal varices, evaluated without any scale, varied from 3.5 +/- 1.4 to 7.5 +/- 4.0 mm between the 12 observers (p less than 0.001). Agreement was maximum for the more developed grade of a sign and minimum for the intermediate grade. The value of kappa indexes in this intercenter study was compared to that obtained in a previous study from one institution: interobserver agreement was significantly better within one center than between different centers. In conclusion, intercenter agreement is good for the size of esophageal varices and the presence of red signs, and poor for all the other signs. The millemetric measurement of esophageal varices diameter, without any scale, appears to be unreliable.(ABSTRACT TRUNCATED AT 250 WORDS)

Thyroid carcinoma in two sisters with familial polyposis of the colon. Case reports and review of the literature.

Multicentric thyroid papillary carcinomas were present in two sisters with familial polyposis of the colon; in one the tumor was found at age 29 and in the other at 26 years of age, respectively 13 and 5 years after colectomy. This association is not fortuitous and should lead to regular examination of thyroid gland in patients with familial polyposis or in Gardner's syndrome patients. It might even be wise to search for adenomas of the colon in young patients with thyroid carcinoma.

Pseudomonas aeruginosa liver abscesses following endoscopic retrograde cholangiography. Report of a case without biliary tract disease.

We report a case of Pseudomonas aeruginosa liver abscesses following endoscopic retrograde cholangiopancreatography (ERCP) in a patient without evidence of biliary tract disease and of any known cause of hepatic infection. Computer tomography (CT) scan was the best method of diagnosis, allowing, through guided percutaneous puncture of the abscesses, isolation of the organism, which was sensitive to carbenicillin. One month of antibiotherapy with repeated aspirations of the largest abscesses was successful. This report suggests that ERCP may induce cholangitic sepsis by inoculating pathogens in the biliary tree even in the absence of extrahepatic obstruction.

[Hepatic brucelloma (pseudotumoral brucellar caseous necrosis of the liver). Study of a case and review of the literature].

We report the case of a 43 year-old Portuguese woman, hospitalized for long-standing fever, fatigue and weight-loss. Biologic investigation demonstrated anicteric cholestasis. Abdominal plain film showed a single hepatic calcification; computerized tomography and ultrasonography of the liver led to the discovery of a large mass, centered by the calcification. C. T.-guided biopsy showed caseiform necrosis, surrounded by histiocytic and lymphocytic cells. Brucella agglutination tests were negative at the beginning of the illness but became positive secondarily. The germ was not isolated from the hepatic fragment. The melitine intradermo-reaction was positive. Outcome was rapidly favorable with antibiotic treatment. Analysis of the 14 previously published cases showed that the most constant features were the hepatic calcifications and the epidemiologic context.
