Could Moesin Be a New Marker for Indicating Progression in Endometrial Cancer?

Aim: This study aims to determine an important parameter in progression from pre-invasive lesions of endometrium to endometrial cancer and also evaluate the effect of this parameter on the progression of endometrial cancer. Material and Method: In our study,30 patients with normal endometrial tissue (group 1), 56 patients who had endometrial hyperplasia without atypia (group 2), 36 patients who had endometrial hyperplasia with atypia (group 3), and 63 patients with endometrial cancer (group 4) were included. Age, parity, body-mass index, systemic diseases, and tumor markers of patients were evaluated. Expression levels of Ezrin, Radixin, and Moesin proteins were immunohistochemically evaluated in terms of frequency, intensity, and score value. Results: When we compared hyperplasia cases with or without atypia; frequency, and score value of ezrin expression and frequency, intensity, and score value of moesin expression was significantly higher in patients who had hyperplasia with atypia (p:0.000 p:0.001 p:0.003, p:0.032 p: 0.035 p:0.015 p:0.005, respectively). It was observed that the frequency and score value of moesin expression were significantly higher in patients with endometrial cancer when compared with patients who had hyperplasia with atypia (p:0.003 p:0.045). The frequency of moesin expression was significantly higher in patients who had postoperative mortality (p:0.030 p:0.039). Conclusion: Increased frequency of moesin expression in the preoperative period in patients with atypical hyperplasia should alert the surgeon in terms of malignancy. If the frequency of moesin expression increases in cases with endometrial cancer, the patient should be followed closely in terms of progression in the postoperative period.

Detection of Bovine Respiratory Syncytial Virus, Pasteurella Multocida, and Mannheimia Haemolytica by Immunohistochemical Method in Naturally-infected Cattle.

INTRODUCTION: The aim of this study was to determine the predisposing effect of bovine respiratory syncytial virus (BRSV) on Pasteurella spp. infection in naturally-induced pneumonia in cattle by immunohistochemical labelling. MATERIAL AND METHODS: Lungs of cattle slaughtered in the slaughterhouse were examined macroscopically, and 100 pneumonic samples were taken. The samples were fixed in 10% neutral formalin and embedded in paraffin by routine methods. Sections 5 µm in thickness were cut. The streptavidin-peroxidase method (ABC) was used to stain the sections for immuno-histochemical examination. RESULTS: BRSV antigens were found in the cytoplasm of epithelial cells of bronchi, bronchioles, and alveoles and within inflammatory cell debris and inflammatory exudate in bronchial lumens. Pasteurella spp. antigens were detected in the cytoplasm of the epithelial cells of bronchi and bronchioles, and in cells in the lumens of bronchi and bronchioles. Eleven cases were positive for only one pathogen (six for BRSV and five for Pasteurella spp.), while 35 cases were positive for 2 pathogens: BRSV plus P. multocida (n = 21) or M. haemolytica (n = 14). CONCLUSION: The presence of high levels of BRSV in dual infections indicates that BSRV may be the main pneumonia-inducing agent and an important predisposing factor for the formation of Pasteurella spp. infections in cattle naturally afflicted with pneumonia.

Rare Undifferentiated Tumour of Thyroid: Primary Thyroid Fibrosarcoma.

Primary thyroid fibrosarcoma cases are very rare. Although it is a known fact that soft tissue sarcomas show slow growth, there have been some cases in literature similar to our case in which there was a fast-growing tumour tissue causing breathing and swallowing difficulties due to painless pressure. For diagnosis, there is no specific clinical or radiological finding. We report a 67-year-old male with a mobile fast-growing mass covering almost all over the neck that appeared 2 months prior to the admission. Laboratory findings showed that the patient was euthyroid. Fine needle aspiration biopsy results are consistent with suspicion of a mesenchymal, histiocytic, epithelial or lymphoid tissue origined malignancy. Patient was taken into surgical operation. The thyroid tissue invaded the main vascular structure, trachea and esophagus. Due to this situation R1 resection was applied. Immunohistopathological examination showed a conventional type of fibrosarcoma. After the surgery, radiotherapy and chemotherapy had been planned and applied. Patients died before the radiotherapy sessions ended. It should be kept in mind that a rapid growth in thyroid tissue can be thyroid fibrosarcoma, there could be a rapid clinical course and poor prognosis after operation.

A comparative study of conventional and liquid-based cervical cytology.

OBJECTIVES: The aim of our study is the comparison of the results of conventional smear (CC) technique and liquidbased cytology (LBC) technique used as cervical cancer screening methods. MATERIAL AND METHODS: The results of 47954 patients submitted to smear screening in our gynecology clinic between January 2008 and December 2014 have been studied. The smear results have been divided into two groups CC and LBC according to the technique used. RESULTS: When considering the distribution within CC group, the results were as follows: intraepithelial cell abnormalities 2,0% (n=619), insufficient sample for analysis 2,1% (n=660), Atypical squamous cells of undetermined significance (ASC-US) 1.8% (n=554), Low grade squamous intraepithelial lesion (LGSIL) 0.1% (n=35), High grade squamous intraepithelial lesion (HGSIL) 0.1% (n=16), Atypical squamous cells - cannot exclude HGSIL (ASC-H) 0.029% (n=9), Atypical glandular cells- not other wise specified (AGC-NOS) 0.012% (n=4), squamous carcinoma 0.003% (n=1). When considering the distribution in LBC group, the results were as follows: intraepithelial cell abnormalities2.1% (n=357), insufficient sample for analysis 0.9% (n=144), ASC-US 1.8% (n=296), LGSIL 0.2% (n=38), HGSIL 0.1% (n=8), ASC-H 0.1% (n=10), AGC-NOS 0.017% (n=3), squamous carcinoma 0.011% (n=2). CONCLUSIONS: Although the rates of epithelial cell abnormalities are similar for both tests, LSIL results are more frequently observed in LBC technique. In LBC technique, the number of insufficient sample for analysis is quite low compared to CC group and thus constitutes an advantage.

Protective effects of carvacrol and pomegranate against methotrexate-induced intestinal damage in rats.

OBJECTIVE: The purpose of this experimental study was to evaluate the efficacy of carvacrol (CVR) and pomegranate (PMG) against methotrexate (MTX)-induced intestinal damage using histopathological and immunohistochemical techniques. METHODS: Thirty-two male Sprague-Dawley rats, weighing 195-250 g, were divided into four groups: control, MTX treatment alone, MTX plus CVR and MTX plus PMG. A single dose of CVR (73 mg/kg) was administered intraperitoneally to group III on the first day of the experiment, PMG (225 mg/kg/day) was administered orogastrically (with a gavage needle) once daily for 7 days and a single dose of MTX (20 mg/kg) was administered intraperitoneally on the second day of the experiment. Intestinal tissues were obtained on 8(th) day, and examined for villus damage, crypt damage, and inflammation. Ki-67 and Caspase 3 staining was used for immunohistochemical evaluation. RESULTS: MTX treatment induced villus shortening and fusion, epithelial atrophy, crypt loss, inflammatory infiltrate in the lamina propria, and goblet cell depletion. The CVR and PMG decreased the severity of intestinal damage caused by MTX treatment. In the MTX-received group, significant inflammatory cell infiltration was observed in the lamina propria. Compared to the MTX-received group, the PMG and CVR groups showed less villus and crypt damage and less inflammation in the lamina propria. Fewer Ki-67 positive cells were observed in the crypts of the MTX-received groups compared to the control group. There were more Ki-67 positive cells in the CVR and PMG groups compared to MTX group. The MTX-received group exhibited more caspase-3 positive cells than the control group, and the number of caspase-3 positive cells were decreased in the CVR and PMG treated groups. CONCLUSION: This study is the first to show that PMG and CVR decrease MTX-related damage and apoptotic activity in intestinal tissue.

Chronic hepatitis B associated with hepatic steatosis, insulin resistance, necroinflammation and fibrosis.

BACKGROUND: The effect of hepatitis B virus (HBV) infection on fatty liver disease is unclear. OBJECTIVES: The aim of this study was to investigate the viral and host causes of fatty liver in chronic hepatitis B (CHB) patients. This study included 88 CHB patients of which 17 were not treated. Liver biopsy was performed in each patient. Group 1 included those with hepatic steatosis (n=28) and group 2 those without hepatic steatosis. The groups were compared in terms of age, body mass index (BMI), Homeostasis Model Assessment- Insulin Resistance (HOMA-IR), viral load, biochemical parameters and histological findings. Patients in group 1 were subdivided according to the degree of steatosis as follows: grade 1 (15 patients, 53.6%), grade 2 (6 patients, 21.4%), and grade 3 (7 patients, 25%). RESULTS: In group 1 (n=28), mean age, BMI, cholesterol, and HOMA-IR were found to be significantly higher than in group 2 (n=60). There were no significant differences in the positivity of viral load, HbeAg, treatment, fibrosis and other laboratory parameters between the two groups. HOMA-IR was the only independent predictive factor of liver steatosis in patients with CHB in logistic regression analysis. CONCLUSION: Hepatic steatosis in CHB patients was associated with host metabolic factors.

Clinical characteristics, treatment and survival outcomes in malignant pleural mesothelioma: an institutional experience in Turkey.

PURPOSE: To compare treatment modalities and investigate potential prognostic factors for survival in patients with malignant pleural mesothelioma (MPM). METHODS: The present study has investigated the data of 150 patients with MPM who were examined and treated in our center from 2005 to 2012. RESULTS: The study included 87 male (58% and 63 female (42) patients. Surgical resection (pleurectomy/decortications (P/D), and extrapleural pneumonectomy (EPP)) was performed in 32 (36.7%) patients; 87 patients (58%) received chemotherapy alone and 16 (10.7%) had surgery, chemotherapy and radiotherapy (trimodal treatment). The median progression free and overall survival (PFS and OS) for all patients were 10.6 and 14.8 months, respectively. No statistically significant difference was observed between the patients who received pemetrexed/cisplatin (N=54) and gemcitabine/cisplatin (N=28) in terms of PFS and OS (p=0.145, p=0.244, respectively). Also, no statistically significant difference was registered between operated and non operated patients (PFS and OS, p=0.416, p=0.095, respectively). There was no difference in both PFS and OS rates between patients who had P/D or EPP (p=0.87, p=0.652, respectively). Log rank analysis: Eastern Cooperative Oncology Group performance status (ECOG PS) (p=0.018), histology (p<0.001), stage (p<0.001) and leukocytosis (p=0.005) were found to be significant prognostic factors of OS. At multivariate analysis, ECOG PS (p=0.016) and stage (p<0.001) were independent prognostic factors for OS. CONCLUSION: Median OS was approximately 1 year. ECOG PS, histological type, stage and presence of leukocytosis were prognostic factors that affected both PFS and OS. EPP or P/D surgical options did not provide difference in terms of survival. Survival rates in patients who received a combination of platinum analogues with pemetrexed or gemcitabine as front-line chemotherapy were similar.

Increased bone mineral density in patients with non-alcoholic steatohepatitis.

AIM: To determine the relationship between non-alcoholic steatohepatitis (NASH) and bone mineral density (BMD). METHODS: A total of 38 patients (25 males) with a diagnosis of histologically proven NASH and 42 healthy controls (24 males) were enrolled in the study. Demographic features, clinical findings, complete blood count and routine biochemical analysis, as well as adrenal, thyroid and gonadal functions, were recorded. Additionally, intact parathormone, 25-OH-vitamin-D3, tumor necrosis factor-α, interleukin-6, interleukin-1, insulin-like growth factor-1 and insulin-like growth factor binding protein-3 levels were measured in both groups. Furthermore, lumbar spine and femoral neck BMD of both groups were measured by the dual-energy X-ray absorptiometry (DXA) method. RESULTS: The mean age was 41 ± 12 years in the NASH group and 43 ± 11 years in the control group. Among demographic features, waist circumference was significantly larger in the NASH group compared to the control group (P < 0.019). Among laboratory parameters, serum triglyceride (P < 0.008), alanine transaminase (P < 0.0001), aspartate transaminase (P < 0.001), alkaline phosphatase (P < 0.016), gamma glutamyl transferase (P < 0.0001), ferritin (P < 0.001) and 25-OH-vitamin-D3 levels (P < 0.0001) were significantly higher in the NASH group compared to the control group. Lumbar BMD was significantly higher in the NASH group compared to the control group (1.057 ± 0.119 g/cm(2) vs 0.941 ± 0.133 g/cm(2); P < 0.001, respectively). In the NASH group, there was no significant relationship between BMD and fibrosis stage in liver biopsy. CONCLUSION: NASH increases BMD and may be related to an elevated serum 25-OH-vitamin D3 level.

Increased caspase-3 immunoreactivity of erythrocytes in STZ diabetic rats.

Eryptosis is a term to define apoptosis of erythrocytes. Oxidative stress and hyperglycemia, both of which exist in the diabetic intravascular environment, can trigger eryptosis of erythrocytes. In this experimental study, it is presented that the majority of erythrocytes shows caspase-3 immunoreactivity in streptozocin- (STZ)-induced diabetic rats. Besides that, caspase-3 positive erythrocytes are aggregated and attached to vascular endothelium. In conclusion, these results may start a debate that eryptosis could have a role in the diabetic complications.

Parachordoma: a recurrent case and review of the literature.

Parachordoma is an uncommon tumor of soft tissue, and the origin is not clear. Recurrence and metastasis are rarely seen. A piecemeal mass measuring 7x4x3 cm was excised from a 28-year-man who had presented with pain and swelling of the right shoulder for 5 years. Histopathologically, the tumor was composed of cells with clear eosinophilic cytoplasm and an epithelioid appearance in a myxoid stroma separated by fibrous tissue with mild pleomorphism and mitotic activity. Tumoral cells were immunoreactive for cytokeratin 8/18, EMA, S-100 and vimentin, immunohistochemically. Recurrence was seen one year after the initial diagnosis. Areas of increased mitotic activity and atypical mitoses were observed in the recurrent tumor. We report this case as recurrence occurred earlier than usual and exhibited malignant features.

Malignant melanoma of the stomach presenting in a woman: a case report.

INTRODUCTION: Malignant melanoma is reported to metastasize to all organs of the human body. Although it is common for it to metastasize to the gastrointestinal tract, a melanoma located primarily in the gastric mucosa is an uncommon tumor. Gastrointestinal metastases are rarely diagnosed before death with radiological and endoscopic techniques. CASE PRESENTATION: In this case report the clinical course and treatment of a woman with melanoma of the stomach, without any other detectable primary lesion, is presented and discussed. A 55-year-old Turkish woman presented to our clinic with complaints of muscle pain and bone pain in the left side of her chest. During an upper gastrointestinal system endoscopy, dark cherry-colored, light elevated, round-shaped lesions were taken from her gastric fundus and from the first part of her duodenum. Biopsies from these samples were determined to be malignant melanoma by the pathologist. CONCLUSION: Metastatic malignant melanoma cases should be examined through endoscopy for gastrointestinal metastases.

Double thyroglossal duct cyst located in the hyoid region and the tongue base: an unusual coexistence.

Thyroglossal duct cysts originate from persistent epithelial remnants of the thyroglossal duct that are present during the descent of the thyroid gland from the foramen cecum to its final position in the anterior neck. Thyroglossal duct may persist anywhere along the descent from the tongue to the thyroid. Lingually localized thyroglossal duct cysts are congenital lesions of the pharynx, which are very uncommon and may cause morbidity and mortality if not treated expeditiously. Double thyroglossal cysts and the complete failure of the obliterative process of thyroglossal duct are very rare in the literature. In this article, we describe a case of two cysts derived from the same thyroglossal duct, one in the hyoid region and the other in the tongue base. To our knowledge, this coexistence has not been described previously in the literature.

Mast cells count and serum cytokine levels in patients with irritable bowel syndrome.

BACKGROUND/AIMS: Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder. Psychological factors and subtle histopathological changes have been implicated in IBS. In some studies, mast cell infiltration has been determined in colon mucosa of the patients with IBS. The aim of this study was to investigate the relationship between mast cell counts and cytokine levels and IBS. METHODOLOGY: 72 consecutive IBS patients fulfilling the Rome III criteria and 50 asymptomatic healthy controls underwent colonoscopic biopsy. 15 patients in diarrhea-predominant IBS group which were performed colonoscopy were made a biopsy from caecum, other 25 patients in diarrhea-predominant IBS and 32 patients in constipation predominant IBS were performed a biopsy from rectum. Additionally, serum cytokines were analysed in the patients with IBS and in control group. RESULTS: The results showed significantly increased mast cells in the IBS-diarrhea group compared to IBS-constipation and the control groups (p < 0.0001). The statistical analysis of the inflammatory cytokine data obtained in the present study showed significantly higher levels for the sIL-2 receptor in the IBS-diarrhea group compared to other groups. CONCLUSIONS: Histopathologic and laboratory data demonstrate low-grade mucosal inflammation in a subset of patients with IBS. Mast cells and cytokines may be related to the pathophysiologic mechanism of IBS.

Ganglioglioma in the nasal cavity: a case report.

Ganglioglioma is a tumor containing both astrocytic and neuronal components. It may occur any where in the central nervous system and spinal cord but is only encountered rarely. Nasal glial heterotopia (also known as ''nasal glioma''), is a rare developmental abnormality seen in a wide age group. Gangliogliomas may also manifest as a nasal glial heterotopia, and neurogenic tumors should be considered in the presence of a nasal mass. In this article, we present a case of ganglioglioma located in the right-nasal cavity. The mass was excised totally through an endoscopic approach. The ganglioglioma developed on a nasal glial heterotopia base. To our knowledge, a ganglioglioma arising from the nasal cavity has not been described previously in the literature.

The effect of long-term extremely low-frequency magnetic field on geometric and biomechanical properties of rats' bone.

Bone is composed of a mineral matrix reinforced by a network of collagen that governs the biomechanical functions of the skeletal system in the body. The purpose of the study was to investigate the possible effect of extremely low-frequency magnetic field (ELF-MF) on geometric and biomechanical properties of rats' bone. In this study, 30 male Sprague-Dawley rats were used. The rats were divided into three groups: two experimental and one control sham. The first and second experimental group (n=10) were exposed to 100 microT and 500 microT-MF during 10 months, 2 h a day, respectively, and the third (sham) (n=10) group was treated like experimental group except ELF-MF exposure in methacrylate boxes. After ELF-MF and sham exposure, geometric and the biomechanical properties of rats' bone, such as cross-sectional area of the femoral shaft, length of the femur, cortical thickness of the femur, ultimate tensile strength (maximum load), displacement, stiffness, energy absorption capacity, elastic modulus, and toughness of bone were determined. The geometric and biomechanical analyses showed that a significant decrease in rats exposed to 100 microT-MF in comparison to sham and 500 microT-MF exposed rats about the values of cross-sectional area of the femoral shaft (P<0.05). Maximum load increased in 100 muT-MF and 500 microT-MF exposed rats when compared to that of the sham rats (P<0.05). The cortical thickness of the femurs of MF-exposed rats (100 microT and 500 microT) were significantly decreased in comparison to that of sham groups' rats (P<0.05 and P<0.001). However, no significant differences were found in the other biomechanical endpoints between each other groups, such as: length of the femur, displacement, stiffness, energy absorption capacity, elastic modulus, and toughness of bone (P>0.05). These experiments demonstrated that 100 microT-MF and 500 microT-MF can affect biomechanical and geometrical properties of rats' bone.

Iloprost, a prostacyclin (PGI2) analogue, reduces liver injury in hepatic ischemia-reperfusion in rats.

PURPOSE: To evaluate the effects of iloprost a prostacyclin analogue on the hepatic IR injury in rats. METHODS: Forty male Sprague-Dawley rats (250-300 g) were divided into four groups each containing 10 rats;(1)--controls: data from unmanipulated animals; (2) sham group: rats subjected to the surgical procedure, except for liver I/R, and given saline; (3) I/R group: rats that underwent liver ischemia for 45 min followed by reperfusion for 45 min; (4) IR/ Iloprost group: rats pretreated with iloprost (10 microg kg-1, i.v). Liver tissues were taken to determine SOD, CAT, GSH, and MDA levels and for biochemical and histological evaluation. RESULTS: The plasma ALT and AST levels were increased in group 3 than in group 4. MDA values and the liver injury score decreased, while the SOD, CAT, and GSH values increased in group 4 compared to group 3. In group 3, hepatocytes were swollen with marked vacuolization. In group 4, there were regular sinusoidal structures with normal morphology without any signs of congestion. CONCLUSION: We demonstrated hepatoprotective effects of iloprost against severe ischemia and reperfusion injury in rat liver.

Screening for Celiac disease in Hodgkin and non-Hodgkin lymphoma patients.

BACKGROUND/AIMS: Celiac disease is an abnormal T cell-mediated immune response against dietary gluten in genetically predisposed individuals. The aim of our prospective study was to evaluate the frequency of Celiac disease in patients with lymphoma and to determine the usefulness of the anti-gliadin and anti-endomysial antibodies (EMA) for diagnosis of Celiac disease in this patient group. METHODS: We studied 119 patients with previously or newly diagnosed non-Hodgkin's lymphoma and 60 patients with Hodgkin's lymphoma who presented at the hematology and medical oncology divisions of Dicle University Hospital in Turkey between December 2002 and January 2006. Serological screening for Celiac disease was performed in all patients by searching for serum anti-gliadin immunoglobulin A and immunoglobulin G, and EMA immunoglobulin A and immunoglobulin G. RESULTS: In the Hodgkin's lymphoma group, anti-gliadin immunoglobulin A was detected in 9 (15%) patients (3 male, 6 female), and antigliadin immunoglobulin G was detected in 21 (35%) patients (15 male, 6 female). In the non-Hodgkin's lymphoma group, antigliadin immunoglobulin A was detected in 6 (5%) patients (2 M male 4 female), and anti-gliadin immunoglobulin G was detected in 30 (25.2%) patients (18 male, 12 female). EMA immunoglobulin A and immunoglobulin G were not detected in the Hodgkin's lymphoma and non-Hodgkin's lymphoma groups. CONCLUSIONS: Our report is the first to describe the frequency of Celiac disease in patients with lymphoma in the southeast region of Turkey. In our study, there was no evidence that Celiac disease is a pre-malignant condition for lymphoma. Serological screening for Celiac disease in lymphoma patients does not seem to be necessary.

OBJETIVO: Avaliar os efeitos do iloprost, um análogo da prostaciclina nos danos causados ao fígado de ratos pela lesão de IR. MÉTODOS: Quarenta ratos machos Sprague-Dawley (250-300 g) foram distribuídos em quatro grupos de dez; - (1) grupo de controle: dados de animais não manipulados; (2) grupo "sham": ratos que sofreram intervenção cirúrgica sem I/R, aos quais foram administrados solução salina; (3) grupo I/R; animais que foram submetidos à isquemia por 45 minutos seguida de reperfusão por 45 minutos; (4) grupo I R/Iloprost: ratos previamente tratados com Iloprost ( 10µ kg-1, i.v). Tecidos hepáticos foram retirados para determinar os níveis de SOD, CAT, GSH, e MDA e para avaliação bioquímica e histológica. RESULTADOS: Os níveis de plasma ALT e AST aumentaram no grupo 3 mais do que no grupo 4. Os valores de MDA e o índice de lesões hepáticas diminuíram, enquanto os valores de SOD, CAT e GSH aumentaram no grupo 4, em comparação com o grupo3. No grupo 3, os hepatócitos se apresentaram edemaciados, e vacuolizados. No grupo 4, havia estruturas sinusoidais regulares, apresentando morfologia normal, sem sinais de congestão. CONCLUSÃO: Demonstramos os efeitos hepato-protetores do Iloprost contra a isquemia grave e o dano de reperfusão no fígado de ratos.
