Sexual dysfunction in female subjects with fibromyalgia

PURPOSE: We investigated sexual function in females with fibromyalgia (FM) and evaluate whether coexistent major depression (MD) has an additional negative effect on sexual function. MATERIALS AND METHODS: A total of 100 female subjects were enrolled in the study, including 40 with FM only, 27 with FM plus MD and 33 healthy volunteers as a control group. The diagnosis of MD was made according to Structured Clinical Interview for Diagnostic and Statistical Manual-IV interview and the Hamilton Depression Rate Scale was used to grade depression. Widespread pain and quality of life were assessed with the Lattinen Pain Scale and Fibromyalgia Impact Questionnaire, respectively. The Female Sexual Function Index (FSFI) was used to assess sexual dysfunction. RESULTS: All subjects were comparable in age, occupation and education. Mean FSFI total score +/- SD was significantly decreased in the FM and FM plus MD groups compared with that in healthy controls (21.83 +/- 5.84 and 22.43 +/- 7.0 vs 28.10 +/- 6.52, respectively, p = 0.001). However, the FSFI score was not significantly different between patients with FM only and FM plus MD (p >0.05). Correlation analysis revealed a negative moderate correlation between total Lattinen pain score and FSFI score in the FM only and FM plus MD groups (r = -0.366, p = 0.047 and r = -0.403, p = 0.018, respectively). FSFI score did not correlate with FIQ and HDRS scores (p >0.05). CONCLUSIONS: This study demonstrates that female patients with FM have distinct sexual dysfunction compared with healthy controls and coexistent MD has no additional negative effect on sexual function. Thus, female subjects with FM should be evaluated in terms of sexual function to provide better quality of life.     

In vivo observation of leukocyte-endothelium interaction in ischemia reperfusion injury with the dorsal window chamber and the effects of pentoxifylline on reperfusion injury

OBJECTIVE: Ischemia reperfusion injury can cause failure in microsurgical operations. Interaction between leukocytes and endothelium is recognized as an integral step in ischemia reperfusion injury. Pentoxifylline is a methylxanthine derivative that has pharmacological properties that can be beneficial in ischemia reperfusion injury. The aim of this study was to investigate the in vivo effect of pentoxifylline on leukocyte-endothelium interaction in ischemia reperfusion injury. METHODS: Intravital fluorescent microscopy was used to observe leukocyte-endothelium interaction in a "dorsal window chamber" model. Twenty-eight postcapillary veins were analyzed in group 1, and twenty-two in group 2. Group 1 received 25 mg/kg pentoxifylline 20 min before reperfusion. Group 2 received an equivalent volume of 0.9% saline at the same time. The period of ischemia was 4 h. RESULTS: Quantification of leukocyte 'sticking' and 'rolling' was done before ischemia and at 30, 60, and 120 min after reperfusion. Offline video analysis was used for evaluating the results. Statistical evaluation showed that pentoxifylline significantly attenuated leukocyte 'sticking' and 'rolling' in postcapillary venules. It was also effective in preventing 'no-reflow' when compared with the control group. CONCLUSION: These results indicate pentoxifylline diminishes leukocyte-endothelium interaction, and may have a therapeutic role in preventing ischemia reperfusion injury in microsurgical operations.     

Computed Tomography in Nonalcoholic Fatty Liver Disease

The value and/or limitations of computed tomography (CT) in assessment of hepatosteatosis are not well studied in nonalcoholic fatty liver disease (NAFLD). We prospectively evaluated the accuracy of CT in assessing the amount of hepatosteatosis in NAFLD patients and the impact of demographic and histopathologic variables on CT images. Forty patients with biopsy-proven NAFLD were eligible. Of these, 10 exhibited hepatic iron overload. Liver and spleen attenuation measurements were obtained and spleen-minus-liver attenuation difference (ΔS–LA) was calculated. A good correlation between ΔS–LA and pathological hepatosteatosis was observed (r = 0.837, P < 0.0001). Liver iron overload did not affect this correlation, although the mean ΔS–LA was significantly lower in patients with iron overload. No correlation was detected between ΔS–LA and hepatic inflammation, fibrosis, or body mass index. We conclude that ΔS–LA derived from CT may be a useful tool for predicting the amount of hepatosteatosis in NAFLD patients as it is not affected by various individual factors.

Peritoneal carcinomatosis of gastrointestinal tumors: Where are we now?

The peritoneal stromal tissue which provides a rich source of growth factors and chemokines is a favorable environment for tumor proliferation. The pathophysiological mechanism of peritoneal carcinomatosis is an individual sequence consisting of genetic and environmental factors and remains controversial. The natural history of the disease reveals a poor median prognosis of approximately 6 mo; however aggressive surgery and multimodal treatment options can improve oncologic outcomes. Considering peritoneal carcinomatosis as though it is a locoregional disease but not a metastatic process, cytoreductive surgery and and intraperitoneal chemotherapy has been a curative option during recent years. Cytoreductive surgery implies a series of visceral resections and peritonectomy procedures. Although the aim of cytoreductive surgery is to eliminate all macroscopic disease, viable tumor cells may remain in the peritoneal cavity. At that point, intraperitoneal chemotherapy can extend the macroscopic disease elimination to microscopic disease elimination. The successful treatment of peritoneal carcinomatosis requires a comprehensive management plan including proper patient selection, complete resection of all visible disease, perioperative intraperitoneal chemotherapy and postoperative systemic chemotherapy. Surgical and oncologic outcomes are strictly associated with extent of the tumor, completeness of cytoreduction and patient-related factors as well as multidisciplinary management and experience of the surgical team. In this review, pathophysiology and current management of peritoneal carcinomatosis originating from gastrointestinal tumors are discussed according to the latest literature.     

Investigation of genome instability in patients with non-alcoholic steatohepatitis

AIM:To evaluate the occurrence of micronucleus(MN),nucleoplasmic bridges(NPBs)and nuclear buds(NBUDs)in the mitogen-stimulated lymphocytes of patients with non-alcoholic steatohepatitis(NASH).METHODS:The study was performed in 25(9 females,16 males)patients newly diagnosed with NASH,and 25healthy subjects of similar ages and genders were used as a control group.None of the controls was known to be receiving any drugs for medical or other reasons or using alcohol.Hepatosteatosis was further excluded by abdominal ultrasound imaging in the control group.The numbers of MN,NPBs and NBUDs scored in binucleated(BN)cells were obtained from the mitogen-stimulated lymphocytes of patients and control subjects.Statistical comparisons of the numbers of BN cells with MN,NPBs and NBUDs and ages between the patients with NASH and control subjects were performed.RESULTS:The mean ages of the patients and the control group were 41.92±13.33 and 41.80±13.09 years(P>0.05),respectively.The values of the mean body mass index(BMI),HOMA-IR,hemoglobin,creatinin,aspartate aminotransferase,alanine aminotransferase,triglyceride,high density lipoprotein,and low density lipoprotein were 31.19±4.62 kg/m2vs 25.07±4.14 kg/m2,6.71±4.68 vs 1.40±0.53,14.73±1.49 g/dL vs 14.64±1.30 g/dL,0.74±0.15 mg/dL vs 0.80±0.13 mg/dL,56.08±29.11 U/L vs 16.88±3.33 U/L,92.2±41.43U/L vs 15.88±5.88 U/L,219.21±141.68 mg/dL vs102.56±57.98 mg/dL,16.37±9.65 mg/dL vs 48.72±15.31 mg/dL,and 136.75±30.14 mg/dL vs 114.63±34.13 mg/dL in the patients and control groups,respectively.The total numbers and frequencies of BN cells with MN,NPBs and NBUDs,which were scored using the CBMN cytome assay on PHA-stimulated lymphocytes,were evaluated in the patients with NASH and control group.We found significantly higher numbers of MN,NPBs and NBUDs in the BN cells of patients with NASH than in those of the control subjects(21.60±9.32vs 6.88±3.91;29.28±13.31 vs 7.84±3.96;15.60±5.55 vs 4.20±1.63,respectively,P<0.0001).CONCLUSION:The increased numbers of MN,N     

Prevalence of Pseudoexfoliation Syndrome in Turkish Patients with Senile Cataract

Purpose: To investigate the prevalence of pseudoexfoliation syndrome (PEX) among Turkish patients with senile cataract. Materials and Methods: Records of 352 eyes of 352 patients who underwent cataract surgery were analyzed in this retrospective study. The presence of PEX, type of cataract, intraocular pressure (IOP), glaucoma, age-related macular degeneration, and systemic diseases (coronary artery disease, hypertension, diabetes mellitus) were recorded. Results: The overall prevalence of PEX syndrome was detected to be 11%. The mean age of PEX patients was significantly higher than without PEX (74.4?±?7.2 years and 69.3?±?11.4 years, respectively, p?=?0.004). The most common cataract type in the PEX patients was mixed-type cataract determined in 51.2% of patients. IOP was significantly higher in eyes with PEX than in eyes without it (16.1?±?4.5?mmHg and 14.7?±?3.8?mmHg, respectively; p?=?0.03). Moreover, the prevalence of age-related macular degeneration was found to be significantly higher, and prevalence of glaucoma slightly higher in PEX patients than without PEX. Conclusion: Pseudoexfoliation syndrome is a common condition in Turkish people. PEX is associated with mixed type of cataract, age-related macular degeneration, and elevated IOP. Therefore, PEX patients should be checked for concomitant diseases.     

Study of FHIT and WWOX expression in mucoepidermoid carcinoma and adenoid cystic carcinoma of salivary gland

Mucoepidermoid carcinoma (MEC) and adenoid cystic carcinoma (ACC) are salivary gland neoplasms with divergent morphological features and clinical behavior. ACC is a basaloid tumor whereas MEC is a glandular epithelial neoplasm. FHIT and WWOX are tumor suppressor genes that encompass the FRA3B and FRA16D fragile sites at chromosomes 3p14.2 and 16q23.3, respectively. In previous studies, we have shown concordant loss of Fhit and Wwox expression in breast cancer, with significantly more frequent loss in cancers of basal-like phenotype. To determine if there is a similar association in salivary gland neoplasms, we designed a study of MEC and ACC of salivary gland on tissue microarrays (TMA). TMAs were constructed from 25 MEC and 19 ACC of salivary gland. Fhit and Wwox protein expression was assessed by immunohistochemical staining of cores on TMAs. Correlations among immunohistochemical markers and histological type were determined by statistical analyses. Significantly reduced Fhit and Wwox expression was observed in ACC (p = 0.002 and p < 0.001, respectively). The results suggest that, as for breast cancer, loss of Fhit and Wwox expression might have a role in the pathogenesis of basaloid differentiation in salivary gland neoplasms; alternatively, differences in chromatin structure at chromosome fragile regions might make fragile genes more accessible to DNA damage and rearrangement early during preneoplastic stages of basaloid cancers. Studies of basaloid tumors of other organ systems may show similar results and these findings may have implications for treatment modalities designed for basal-like tumors.
