Effects of probiotics on the severity of experimental acute pancreatitis.

OBJECTIVE: This study was designed to evaluate the effects of probiotics on the severity of experimental acute pancreatitis. DESIGN: Experimental study. SETTING: Experiments were done in a laboratory at Haydarpasa Numune Teaching and Research Hospital. SUBJECTS: A total of 50 Wistar rats were randomly divided into five groups. INTERVENTIONS: Group 1 was control group. Group 2 received an intraperitoneal injection of a 20% solution in 0.15 mol/l NaCL. Group 3 was injected NaCL and fed with probiotics. Acute pancreatitis was induced in rats by intrperitoneal injection of L-Arginine in groups 4 and 5. The rats in group 5 were treated with probiotics. The pancreas was removed for histologic examination. Evaluation of the pathologic changes was done by a new combined histopathologic grading scale. RESULTS: The mean scores of fibrosis, acinar cell loss, oedema, parenchymal necrosis, mononuclear cells infiltration, polymorphonuclear leucocytes infiltration, ductal damage and atypical reactive regeneration in group 5 were significantly lower than group 4. CONCLUSIONS: We demonstrated that enteral feedings with added probiotics can reduce the severity of acute pancreatitis. SPONSORSHIP: None.

Breast carcinoma with three coexistant type of metaplasia: sarcomatoid, giant cell and squamous differantiation.

We report on a women with metaplastic carcinoma of the right breast. After diagnosis she had a simple mastectomy operation. Pathological investigations were carried out on mastectomy material. Immunohistochemical analyses were performed. Bizarre, malignant giant cells and diffuse inflammatory reactions were predominantly noted. Sarcomatous metaplasia and rare squamous metaplasia were also seen. There was not any area of classic intraductal, invasive ductal, lobular or papillary carcinoma. The patient is still alive and well for more than five years. This uncommon case is described and discussed, and the related literature is reviewed.

Fetal biometry: size and configuration of the third ventricle.

PURPOSE: To evaluate the normal configuration and size of the third ventricle in second and third trimester fetuses in a normal population, and to compare our values with those of previously published studies. MATERIAL AND METHODS: Evaluation of fetal third ventricular width and configuration was obtained by antenatal ultrasonography in 474 fetuses with gestational age between 12 weeks and term (mean 28 weeks). Percentiles for third ventricle width were estimated by combining separate fractional polynominal regression models fitted to the mean and standard deviation, assuming that the measurements had a normal distribution at each gestational age. Appearance of the third ventricle was correlated with each gestational age. RESULTS: The third ventricle could be visualized in 471 (99%) of 474 fetuses. The 97th percentile of the third ventricle in preterm fetuses was measured as 3.6 mm in size. The third ventricle was seen as a single echogenic line in 153 (32.4%) of 474 fetuses. Two-hundred-and-ninety-nine (61.5%) of all fetuses had parallel echogenic lines outlining a fluid-filled lumen. V-shaped third ventricular configuration was seen in only 28 (5.9%) of the fetuses. From 24 weeks to term, parallel echogenic lines were the most commonly (83.7% to 79.6%) encountered configuration for the third ventricle. CONCLUSION: The 97th percentile of the third ventricle in preterm fetuses was measured as 3.6 mm in size. In the early second trimester, 77% of the fetuses had a single echogenic line appearance on ultrasonography. As the brain and ventricular structures mature, a parallel echogenic line becomes the prominent ultrasonography appearance (>80% of fetuses) in third trimester healthy fetuses.

Coexistence of lactating adenoma and invasive ductal adenocarcinoma of the breast in a pregnant woman.

A 36 year old pregnant woman was admitted to hospital complaining of an enlarging mass in her left breast. Histopathological examination of the mastectomy specimen revealed a high grade infiltrating ductal adenocarcinoma intermixed with a lactating adenoma. Lactating adenomas are rare entities but are the most common masses that occur during pregnancy. Although they are not thought to carry an increased risk of cancer there are two other case reports in the literature of a lactating adenoma associated with an infiltrating carcinoma. In this case, areas where the lactating adenoma and the infiltrating carcinoma were intermixed could be identified. This case could simply be a collision tumour, although the possibility of an invasive carcinoma arising within a lactating adenoma cannot be ruled out. Because of the relative lack of experience with lactating adenomas, the question of an increased association with carcinoma development remains unclear.

Isolated metastasis of malignant melanoma into follicular carcinoma of the thyroid gland.

A 38-yr-old woman with a history of malignant melanoma (MM) presented with a thyroidal nodule. Fine needle aspiration biopsy of the thyroid was consistent with metastatic MM. The patient underwent thyroidectomy: microscopic examination revealed a follicular carcinoma nodule harboring a focus of metastatic melanoma. On review of the fine needle aspiration biopsy specimen, the population of cells with more uniform nuclei with focal follicle formation, which initially was interpreted as cells originating from normal thyroid tissue, was seen to actually represent the follicular carcinoma component. Tumor-to-tumor metastasis is an interesting phenomenon and there are only few cases of MM metastasis to other tumors. MM metastasis into a neoplastic thyroid nodule is a very rare combination and may be explained because the nodule in question represents the most highly vascularized component of the thyroid.

Synergistic effects of carboxymethylcellulose and low molecular weight heparin in reducing adhesion formation in the rat uterine horn model.

OBJECTIVE: To investigate the effect of sodium carboxymethylcellulose (SCMC) and the combination of low molecular weight heparin (LMWH) with SCMC in the prevention of intraperitoneal adhesion. DESIGN: Thirty-eight rats underwent bilateral surgical injury to the uterine horn and the parietal peritoneum. In 13 rats, a solution of SCMC was instilled at laparotomy. In 11 rats, LMWH was delivered on to serosal and peritoneal defects, and SCMC was instilled. As a control group 14 rats were included in the study. SETTING: Surgical Research Laboratory, Erciyes University. PARTICIPANTS: Female Wistar-Albino rats, weighing 200 to 250 g each. MAIN OUTCOME MEASURES: Adhesions between the uterine horn and the abdominal sidewall were scored for extent and severity two weeks after the initial surgery. RESULTS: Although the mean adhesion score both in the SCMC group (2.8, s.d. 1.15) and in the SCMC with LMWH group (1.6, s.d 1.18) was found to be significantly lower than in the control group (3.4, s.d. 0.89) (p < 0.05 and p < 0.001, respectively), more favorable adhesion prophylaxis was achieved in the SCMC with LMWH group in comparison with the SCMC treatment group without any hemorrhagic complications (p < 0.001). CONCLUSION: We conclude that SCMC with LMWH are highly effective in reducing postoperative adhesions in this animal model. SCMC with LMWH appears promising in adhesion prophylaxis.

Control of plasma glucose with somatostatin analogue (SMS 201-995) during surgical removal of insulinomas.

Prevention of hypoglycaemia may sometimes be difficult in the operative period of insulinoma when parenteral volume overload is contraindicated due to severe cardiac failure. We investigated the effects of octreotide on hypoglycaemia during operations in two patients with insulinoma, one of whom had severe congestive heart failure. We found no hypoglycaemic values by using octreotide 100 micrograms administered subcutaneously one hour before surgery. Octreotide therapy can safely be used before surgery to prevent hypoglycaemia in patients with insulinoma.
