Demographic and clinicopathological characteristics of nonalcoholic fatty liver disease in the East-Southeastern Anatolia regions in Turkey.

OBJECTIVE: To identify the demographic and clinicopathological characteristics of patients diagnosed with nonalcoholic fatty liver disease (NAFLD) and the risk factors for fibrosis based on histopathological findings in East-Southeastern Anatolia regions in Turkey. SUBJECTS AND METHODS: The study included a total of 93 patients diagnosed with NAFLD from 5 different centers. Histopathological findings were evaluated by dividing them into four categories using Matteoni classifications. Cases with fibrosis were further evaluated using Brunt classifications. RESULTS: The patients with a nonalcoholic fatty liver were in the 3rd and 4th decade age groups. The mean age was 38 years, 76% of the patients were male, 85% were overweight, 37% were obese, 18% had type 2 diabetes mellitus, and 80.6% had hyperlipidemia. A multiple regression analysis showed that age, type 2 diabetes mellitus, and aspartate aminotransferase (AST) levels were linked with the severity of the disease. Of the 93 patients, 55 (59.1%) had fibrosis, of which 10.8% were classified as severe. The severity of fibrosis was significantly higher in obese patients. CONCLUSIONS: The risk factors for severity of NAFLD included advanced age, type 2 diabetes mellitus and serum AST level, while the risk factor for the severity of fibrosis was obesity.

A case of linear lichen planus.

Linear lichen planus (LLP) is a very rare form of lichen planus (LP) characterized by a linear distribution of the lichenoid lesions. It usually follows the lines of Blaschko with unilateral involvement. We report such a case of LLP. A 50-year-old man presented with slightly pruritic, linear, violaceous, papular lesions on the right side of his jaw. A biopsy specimen demonstrated the typical histology of LP. Based on the clinical and pathological findings, the diagnosis was LLP.

A comparison of leptin and ghrelin levels in plasma and saliva of young healthy subjects.

In the last 10 years, saliva has been increasingly used as a diagnostic fluid and in predictions of disease progression. Leptin and ghrelin are synthesized in several tissues including the salivary glands. The action of ghrelin is antagonistic to that of leptin. This study was undertaken to measure and compare the saliva ghrelin-leptin and plasma ghrelin-leptin levels in healthy young subjects. In 30 healthy subjects, after an overnight fast, saliva and plasma leptin levels were measured using the ELISA method while saliva and plasma immunoreactive ghrelin levels were measured using a commercial radioimmunoassay (RIA). The latter uses 125I-labeled bioactive ghrelin as a tracer and a rabbit polyclonal antibody raised against full-length octanoylated human ghrelin (Phoenix, Europe, Karlsruhe, Germany). The results of this investigation revealed that saliva leptin levels (6.19+/-2.10 microg/l) were lower than plasma levels (7.39+/-3.23 microg/l) while saliva ghrelin levels (188.5+/-84.7 pg/ml) were higher than plasma levels (126.4+/-38.5 pg/ml), when male and female subjects were considered together. Saliva leptin levels (5.93+/-1.94 microg/l) were lower than plasma levels (6.22+/-2.92 pg/ml) while saliva ghrelin levels (190.3+/-80.2 pg/ml) were higher than plasma levels (120.4+/-35.7 pg/ml) in young males. Saliva leptin levels (6.47+/-2.29 microg/l) were lower than plasma levels (8.73+/-3.14 microg/l) while saliva ghrelin levels (183.2+/-90.2 pg/ml) were higher than plasma levels (129.3+/-42.8 pg/ml) in young females, and both saliva and plasma leptin levels were slightly lower in male subjects in comparison with female subjects. Also, Immunohistochemistry study indicated that ghrelin positivity was found in ductus epithelium of salivary gland. We have demonstrated for the first time that saliva ghrelin levels were higher than in plasma while saliva leptin levels were almost the same as in plasma. Measurements of ghrelin and leptin in saliva is non-invasive, simple, and generally much preferred by patients and thus may be an acceptable alternative to plasma sampling.

Giant mesenteric lipoma as a rare cause of ileus in a child: report of a case.

Mesenteric lipoma is a rare benign tumor of mature fat cells. Although generally asymptomatic, it occasionally causes abdominal pain, ileus, and small bowel volvulus, depending on its location and size. A definitive diagnosis can be made by pathological examination. Ultrasonography and abdominal computed tomography show this lesion as a well-defined, homogeneous mass with fat density surrounded by a thin capsule. Because of its rare etiologic origin, we report the case of a 7-year-old girl with a mass in the abdomen and ileus, found to be caused by a mesenteric lipoma.

Influence of some substances on bacterial translocation in the rat.

An experimental study was planned to determine the effect of zinc, levamisole, misoprostol (prostaglandin(1) analog), and melatonin on the bacterial translocation (BT) that develops in rats after major resection of the liver. To this aim, six groups were formed, each consisting of six rats. Except for the control and sham groups, zinc solution 1 ml/day, (prepared in a way to include zinc sulfate equivalent of 5 mg pure zinc/ml) was given to the zinc groups, levamisole 25 mg/kg/day to the levamisole group, misoprostol 200 mg/kg/day to the misoprostol group, and melatonin 20 mg/kg/day to the melatonin group for 3 days before the operation. After the preoperative administration of 10(10) colony-forming units of Escherichia coli to the experimental groups, the abdomen was opened in the sham group, and only the connections around the liver were cut. In the test groups a 70% liver resection was undertaken. Laparotomy was carried out on all the rats 24 hours after the operation; blood samples were obtained for polymerase chain reaction (PCR) analysis and tissue samples from the terminal ileum for histopathologic examination. PCR results for BT were positive for the control and sham groups, with the difference between these two groups not significant (p > 0.05). A statistically significant decrease was found in the BT of all the treatment groups compared to the control group (p <0.05). The histopathologic examination of terminal ileum in the control group revealed that the inflammatory infiltration was significantly less than that in the other groups (p <0.05).
