Malignant mesothelioma is an uncommon neoplasm arising in body cavities lined by the mesothelium. Immunohistochemical stains are useful for making a diagnosis, but the correct combination of antibodies as should be selected in a comprehensive assessment. A peritoneal origin combined with desmoplastic histology is an extremely rare disease entity. Here, we report a case of the primary peritoneal malignant mesothelioma. A 53-year-old man admitted to the hospital with abdominal distension and pelvic pain. In laparotomy, peritonitis carcinomatosa situation was exposed. Multiple biopsies were taken from omentum, peritoneum and fascia. Calretinin, WT-1, D2-40, keratin 5/6, mesothelin, keratin 7, keratin 20, CD99, CEA, smooth muscle actin, desmin, CD34 and S-100 were negative. With these findings tumor was evaluated as desmoplastic malignant mesothelioma of the peritoneum. Currently, no established standard treatments for malignant peritoneal mesothelioma, but early diagnosis by exploratory laparotomy followed by chemotherapy may have contributed to longer survival for patients.

Introduction: Recently, it has been shown that hematological parameters may be used as markers of inflammatory response. In this study, the authors aimed to identify the potential roles of the neutrophil-lymphocyte ratio (NLR) and other hematological markers in the evaluation of hidradenitis suppurativa (HS), a chronic, recurrent inflammatory disease., Materials and Methods: A total of 35 patients, diagnosed with HS between January 1, 2012 and December 31, 2014, were categorized into 3 groups according to the Hurley staging system. The basic patient demographics, the anatomic regions involved, and the hematological parameters including NLRs were evaluated in the present retrospective chart review., Results: Hemoglobin, mean corpuscular volume, and mean corpuscular hemoglobin levels were greater in stage I than stage III, while hematocrit, red cell distribution width (RDW), mean platelet volume, mean corpuscular hemoglobin concentration levels, and platelet counts did not differ between the stages. White blood cell and neu- trophil counts were higher in stage III than stage II, while lympho- cyte counts were lower in stage III than stage II. The NLR of stage I was detected as being significantly higher than stage II and lower than stage III., Conclusion: The present study shows hematological markers, and NLR in particular may be related to the severity of HS. Further studies are required to demonstrate the significance of NLR in the evaluation of HS.

We present a case of a 40-year-old woman with small-cell carcinoma (SCC) of the rectum. She had profuse bleeding in rectum for 5 d. By colonoscopy, polyps were determined in the rectum and biopsies were carried out. Histopathologically, the polyps were adenomatous. Because of the profuse bleeding in rectum, she underwent low anterior resection. After the diagnosis of SCC, she received intravenous chemotherapy with standard doses of siklofosfamid, adriamycin, and vepesid. Nevertheless, intracranial metastases were revealed and she died 6 mo after the operation.

The role of epidermal growth factor (EGF), a polypeptide containing 53 amino acids, on protection and repair of ethanol-induced gastric mucosal injury was investigated in rats. In addition, the effects of EGF on the gastric damage were evaluated histopathologically. We used 48 Spraque-Dawley rats which were divided into [corrected] three groups as control rats, ethanol treated rats and ethanol+EGF treated rats. The ethanol group was given a gastric gavage containing 1 ml of 80% ethanol (v/v) prepared in distilled water. EGF (100 microg/kg) was given by intragastric gavage 30 min before the administration of ethanol. We studied histopathological evaluation and the histochemical heterogeneity of mast cells and its degree of degranulation. Besides, gastric tissue malondialdehyde (MDA), protein sulfhydryl groups (SH), and protein carbonyl levels were measured. EGF treatment stabilized mast cells degranulation and had lower polymorphonuclear leukocytes (PMNL) infiltration, ulcer index, histamine, and MDA; protein carbonyl levels were also lower, compared to the non-treated animals. EGF exerts a protective effect on gastric mucosa to ethanol-induced gastric injury probably through antioxidant and mast cell stabilizing mechanism.

Background/aims: Anastomotic leaks are continuing to be the source of major morbidity in colorectal surgery. Previous studies have shown that leptin acts as a growth factor for several cell types. The aim of this study was to evaluate the effect of leptin on healing of colonic anastomoses in rats., Methodology: Forty-eight rats were divided into 5 groups. Group I (n=8) sham; group II (n=10) control; right colonic anastomosis, group III (n=10); following right colonic anastomosis, treated with leptin twice-daily 1 mg/kg intraperitoneally, group IV (n=10); before right colonic anastomosis, 45 min of colonic ischemia has been created, group V (n=10); following 45 min of colonic ischemia and right colonic anastomosis, leptin was given twice-daily 1 mg/kg intraperitoneally. On the 7th postoperative day relaparotomy was performed. Bursting pressure (BP), tissue hydroxyproline concentrations (THPC), and histopathologic properties of anastomoses; vascular tissue proliferation (VTP), collagen tissue proliferation (CTP), polymorphonuclear leukocyte infiltration (PMNLI), mononuclear leukocyte infiltration (MNLI) were analyzed and results were compared statistically., Results: BP and THPC were found to be significantly higher in group III and group V in comparison with group II and group IV respectively (P<0.05). Histopathologically, leptin significantly increased VTP, CTP, MNLI (P<0.001), and significantly decreased PMNLI (p<0.05) on non-ischemic and ischemic colonic anastomoses., Conclusions: Leptin can be used safely in colorectal surgery since it accelerates the healing of colonic anastomoses.
