Background and Objectives: Tinnitus affects individuals’ quality of life, and multiple surveys have been conducted to assess this effect. One questionnaire used is the Tinnitus Primary Function Questionnaire. The aim of this study was to assess the reliability and validity of the Central Kurdish version of the Tinnitus Primary Function Questionnaire (TPFQ-CK). Subjects and Methods: We obtained permission from the originator of the TPFQ to proceed with this study. The English version was translated into Central Kurdish, following guidelines for the cross-cultural adaptation of health-related quality-of-life measures. A total of 205 participants who self-reported having subjective tinnitus for more than 3 months were included in this study. The TPFQ-CK and Tinnitus Handicap Questionnaire (THQ) were administered to all participants. Additionally, pure-tone audiometry was conducted. Results: Internal consistency of the TPFQ-CK was reflected in the total score (Cronbach’s alpha=0.933), and excellent consistency was present in test-retest reliability (intraclass correlation coefficient=1.000). The concordance correlation coefficient (concordance correlation coefficient=0.999) of the total TPFQ-CK score revealed high concordance and correlation between the two evaluations. The good construct validity of the TPFQ-CK was evidenced by the strong correlation (r=0.895) between the TPFQ-CK and THQ scores. Conclusions The TPFQ-CK is a valid and reliable assessment tool for evaluating the influence of tinnitus on the quality of life of Central Kurdish speakers with tinnitus.

Microtome is a mechanical instrument used to cutbiological specimens into very thin segments formicroscopic examination. Biological specimens can bepresented in many ways. But more often, thesespecimens are embedded in paraffin wax blocks andthe commonest way of sectioning these specimens canbe achieved by the microtome. The earliest form of themicrotome enabled free hand sectioning of fresh orfixed material using a sharp razor. Modern microtomesare precision instruments designed to cut uniformlythin sections of a variety of materials for detailedmicroscopic examination. Central to the production ofgood sections is the microtome knife. Microtomyvirtually begins and ends with a sharp, blemish-freecutting edge. The introduction of disposable blades hasmade easier the production of good quality, thinsections, but they are often unsatisfactory forsectioning harder tissues, especially bone. A sharp knifeedge free from imperfections is essential for theproduction of good sections. Since many types ofmicrotomes are commercially available in the market,choosing the right microtome is essential forproducing the best result as required. A classificationis proposed that unifies and organizes the variousmicrotomes based on the mode of operation.

OBJECTIVE: To evaluate thyroid function and hormonal profile in women with polycystic ovary syndrome (PCOS). METHODS: A case-control study was conducted at Saad Abualila Center, Khartoum, Sudan. The cases were women with confirmed PCOS based on Rotterdam criteria. The controls were infertile women with no evidence of PCOS. The socio-demographic characteristics and medical history were gathered using a questionnaire. Thyroid hormones (thyroid-stimulating hormone, free tri-iodothyronine, and free thyroxine), anti-thyroid peroxidase, and anti-thyroglobulin antibodies were measured. RESULTS: While there were no significant differences in the age and haemoglobin levels of the two studied groups (55 women in each arm), body mass index was significantly higher in women with PCOS. There were no significant differences in the levels of thyroid-stimulating hormone, luteinizing hormone, follicle stimulating hormone, luteinizing hormone/follicle stimulating hormone, anti-thyroid peroxidase, anti-thyroglobulin antibodies, cholesterol, triglycerides and low-density lipoprotein cholesterol between the cases and the controls. The mean±standard deviation of free tri-iodothyronine (3.50±0.2 vs. 3.38±0.3 pg/mL, P=0.040) and median (interquartile) high-density lipoprotein cholesterol (37.0 [34.0 to 42.0] vs. 35.80 [29.0 to 41.0] mg/dL, P=0.015) were significantly higher in PCOS patients compared with the control group. In linear regression, PCOS (0.151 pg/mL, P=0.023) and anti-thyroid peroxidase levels (-0.078 pg/mL, P=0.031) were significantly associated with free tri-iodothyronine. CONCLUSION: Free tri-iodothyronine was a significantly higher among PCOS patients compared with the control group.

Objective: To evaluate a novel polyherbal formulation (BSVT) containing the standardized extracts from the leaves of Boerhavia diffusa, Solidago virgaurea, Vitex negundo, and thymoquinone in CCl4 induced hepatorenal toxicity in rats. Methods: A total of 36 rats were divided into six groups including normal control, CCl4 (2 mL/kg, i.p.), CCl4 (2 mL/kg, i.p.) + Cystone? (750 mg/kg p.o.), CCl4 (2 mL/kg, i.p.) + BSVT (25 mg/kg, p.o.), CCl4 (2 mL/kg, i.p.) + BSVT (50 mg/kg, p.o.), and CCl4 (2 mL/kg, i.p.) + BSVT (100 mg/kg, p.o.). All treatments were given for four weeks. Serum levels of aspartate transaminase, alanine transaminase, alkaline phosphatase, cholesterol, total protein, serum urea, blood urea nitrogen and creatinine were assessed. Superoxide dismutase, malondialdehyde, and glutathione peroxidase were evaluated in tissue homogenate. The histopathological study of liver and kidney tissues was also done. Results: Aspartate transaminase, alanine transaminase, alkaline phosphatase, cholesterol, serum urea, blood urea nitrogen and creatinine were significantly elevated (P<0.001) while total protein was considerably reduced in the CCl4 group as compared to the normal control (P<0.001), which indicated hepatorenal toxicity. In addition, superoxide dismutase and glutathione peroxidase activities were significantly decreased (P<0.001) while malondialdehyde levels were increased markedly (P<0.001). Treatment with BSVT formulation recovered these parameters towards a normal level in a dose-dependent manner. Conclusions: BSVT formulation ameliorates the hepatorenal toxicity in a dose-dependent manner. Furthermore, clinical studies are required to confirm its efficacy.

PURPOSE: To compare high and low inferior mesenteric artery (IMA) ligation in a large number of patients, and investigate the short-term and long-term outcomes. METHODS: This retrospective study compared outcomes between high IMA ligation and low IMA ligation with dissection of lymph nodes (LNs) around the IMA origin. A total of 1,213 patients underwent elective low anterior resection with double-stapling anastomosis for stage I–III rectal cancer located ≥6 cm from the anal verge (835 patients underwent IMA ligation at the IMA origin; 378 patients underwent IMA ligation directly distal to the root of the left colic artery along with dissection of LNs around the IMA origin). RESULTS: There was no difference in anastomotic leakage rate between groups. The 2 groups did not significantly differ in intraoperative blood loss, perioperative complications, total number of harvested LNs, and metastatic IMA LNs. However, more metastatic LNs were harvested in the high-tie than in the low-tie group (1.3 ± 2.9 vs. 0.8 ± 1.9, P = 0.002), and the incidence of positive pathologic nodal status was higher in the high-tie group (37.9% vs. 28.6%, P = 0.001). The 5-year local recurrence-free and metastasis-free survival rates were similar between groups, as were the 5-year overall and cancer-specific survival rates. CONCLUSION: Low IMA ligation with dissection of LNs around the IMA origin showed no differences in anastomotic leakage rate compared with high IMA ligation, without affecting oncologic outcomes. High IMA ligation did not seem to increase the number of total harvested LNs, whereas the ratio of metastatic apical LNs were similar between groups.

PURPOSE: To compare the expression of survivin and its association with clinicopathological criteria in major types of urinary bladder carcinoma, specifically, transitional cell carcinoma with and without squamous differentiation and squamous cell carcinoma. MATERIALS AND METHODS: Immunohistochemical staining for survivin and Ki67 was performed on paraffin-embedded sections of 104 carcinomas: 52 transitional cell carcinoma, 20 transitional cell carcinoma with squamous differentiation, and 32 squamous cell carcinoma. Expression of survivin in >10% of tumor cells was described as altered survivin status. Ki67 staining in >20% of tumor cells was described as a high proliferation index. RESULTS: Altered survivin expression was detected in 60/104 specimens (58%) and was significantly more frequent in transitional cell carcinoma (78%) than in squamous cell carcinoma (38%) or transitional cell carcinoma with squamous differentiation (40%) (p<0.0001). In transitional cell carcinoma but not in squamous cell carcinoma, altered survivin status was associated with higher tumor grade, higher proliferation index, and recurrence. In the whole specimens, altered survivin expression was significantly associated with advanced stage (p<0.001), recurrence (p=0.005), distant metastasis (p<0.001), and death (p=0.001). In the multivariate analysis, altered survivin was an independent poor prognostic factor for recurrence. CONCLUSIONS: Unlike in transitional cell carcinoma, alteration of survivin expression in squamous cell carcinoma occurs less frequently and is not associated with features of tumor aggression or patient outcome. These findings raise a question: are urinary bladder carcinoma patients with squamous cell carcinoma type suitable candidates for survivin vaccine? This is an important question to be answered before approving the vaccine in management.
