Translation, cultural adaptation, initial reliability, and validation of Turkish 15D's version: a generic health-related quality of life (HRQoL) instrument

This article describes the adaptation of the Finnish 15D standardized measure of health-related quality of life (HRQoL) instrument for use in Turkey and assesses its psychometric properties. The HRQoL is measured in a sample of 75 patients with Type 2 diabetes using both 15D and Nottingham Health Profile (NHP) instruments. The internal consistency within the domains of 15D was high, with Cronbach's alpha values 0.89 for 15D scale and 0.89 for NHP. Significant correlations were observed between the scores of similar domains of 15D and the NHP in general health perception supporting the construct validity of the new 15D Turkish version. Overall, the results indicated that the adaptation of the 15D for use in Turkey was successful. The Turkish version was found to be a reliable and valid instrument. It is suitable and applicable to both clinical and population-based studies for the measurement of HRQoL in Turkey.     

Diagnosis, treatment and prognosis of carcinoid tumour of the ampulla of Vater: long-term follow-up of a case

Carcinoid tumours of the gastrointestinal tract are most commonly localized in the appendix, followed by the small intestine and the rectum. Carcinoid tumours of the ampulla of Vater are extremely rare. In this report, we present a long-term follow-up of a new case with carcinoid tumour of the ampulla of Vater.     

The effect of granulocyte macrophage-colony stimulating factor on bacterial translocation after administration of 5-fluorouracil in rats

BACKGROUND: After surgical resection for colorectal carcinoma there is a high recurrence rate and, therefore, adjuvant chemotherapy may be useful in some patients. 5-Fluorouracil (5-FU) is the most commonly used chemotherapeutic agent in the management of patients with colorectal cancer. However, gastrointestinal injury induced by chemotherapeutic agents may result in bacterial translocation from the gut into the systemic circulation. Granulocyte macrophage-colony stimulating factor (GM-CSF) may be used to prevent this side effect by means of macrophage activity stimulation. MATERIALS AND METHODS: A total of 45 rats were divided into three groups. Control group received intraperitoneal saline solution, 5-FU and GM-CSF groups received 50 mg/kg/day 5-FU intravenous infusion and GM-CSF group also received 200 ng/day GM-CSF subcutaneously for 6 days. Intestinal tissue was also sampled for pathological examination at day 7. Plasma levels of tumor necrosis factor-alpha and interleukin-6 were determined, bacterial translocation was quantified by lymph node, liver and spleen culture, and plasma endotoxin content was measured. RESULTS: White blood cell counts of the 5-FU rats were significantly lower than in the control and GM-CSF groups (P < 0.01). The plasma endotoxin, tumor necrosis factor-alpha and interleukin-6 levels in the 5-FU and GM-CSF groups were significantly increased at day 7 compared with the control groups (P < 0.01), but these levels were significantly lower in the GM-CSF group compared to the 5-FU group (P < 0.01). 5-FU intervention caused significant increase in the frequencies of bacterial translocation at liver, spleen, mesenteric lymph node, and portal blood. Compared with 5-FU group, GM-CSF decreased the bacterial translocation (P < 0.01). CONCLUSIONS: This study observed that the administration of 5-FU resulted in bacterial translocation. Activation of inflammatory response with GM-CSF is highly effective in prevention of bacterial translocation in 5-FU interventions.     

Effect on Gastric Emptying and Weight Reduction of Botulinum Toxin-A Injection into the Gastric Antral Layer: An Experimental Study in the Obese Rat Model

Background: We investigated the effects of Botox-A on weight loss and gastric emptying in an experimental obese rat model. Although there is evidence of weight loss in normal-weight rats after Botox-A injection, there are no studies indicating the effect of Botox-A injection on weight loss and gastric emptying time in obese rats. Methods: 37 female Wistar Albino rats were given high calorie diet for 90 days. They were separated into 3 groups. The first group (Botox group) consisted of 15 obese rats whose gastric antrum was injected with 20 U of Botulinum Toxin Type A. The second group (Saline group) consisted of 15 obese rats whose gastric antrum was injected with 20 U of saline. The third group (Control group) had no surgical intervention. Gastric scintigraphy was performed in the 3 groups pre- and postoperatively. Results: The saline group had a weight reduction in the early postoperative days but began to gain weight thereafter. The mean weight of the Botox group between the 16th and 28th days postoperatively was significantly lower than the mean weights of the control and the saline groups (P<0.05, P<0.001). The results of gastric emptying scintigraphy in all 3 groups at day 20 revealed significantly higher T1/2 values in the Botox-A group when compared to the results of the control and saline groups (P<0.001). Conclusion: Botox-A application to the gastric antrum in obese rats leads to weight loss by increasing the gastric emptying time.     

Anatomical dimensions of anterior bundle of ulnar collateral ligament and its role in elbow stability

OBJECTIVE: To study the anatomical dimensions of the anterior bundle of ulnar collateral ligament and its role in elbow instability. METHODS: We studied 20 elbows of 10 cadavers. Anterior bundle of ulnar collateral ligament was dissected in all elbows and its anatomical length and width were measured. After measuring it, we assessed the role of the anterior bundle of ulnar collateral ligament in the medial elbow joint stability, with the capsule, the radial head and anterior bundle of ulnar collateral ligament being cut. RESULTS: The mean right length of the anterior bundle of ulnar collateral ligament was 21.10 +/- 6.29 mm and the mean left length was 21.70 +/- 5.31 mm. The mean right width of the anterior bundle of ulnar collateral ligament was 12.70 +/- 2.79 mm and the mean left width was 13.90 +/- 2.37 mm. Anterior bundle of ulnar collateral ligament was found to be the main stabilizer of the valgus stress. The anterior capsule and the radial head also make contributions to this stability. However, when anterior bundle of ulnar collateral ligament is cut, the radial head and the anterior capsule fails to maintain the stability against valgus stress. CONCLUSIONS: The anatomical dimensions of the anterior bundle of ulnar collateral ligament are important for a surgeon when graft is used in reconstructing this ligament. Our study is an initiator of this topic and we believe that with larger series, more reliable anatomical measurements can be obtained. We also showed that the anterior bundle of ulnar collateral ligament is the main medial stabilizer of the elbow joint.     

Serum IL-18 levels in tuberculosis: comparison with pneumonia, lung cancer and healthy controls

OBJECTIVE: The aim of the present study was to document the serum IL-18 levels in patients with pulmonary tuberculosis (P-TB), extrapulmonary tuberculosis (EP-TB), pneumonia, lung cancer and in healthy controls, and to investigate whether it may assist in the differential diagnosis of P-TB. METHODOLOGY: A total of 116 patients were included in the study. The study population consisted of patients with P-TB, EP-TB, pneumonia and lung cancer and controls. P-TB patients were graded according to sputum positivity and extent of disease. Serum levels of IL-18 (ELISA) were compared between groups and with other clinical measures of disease. RESULTS: Compared with the controls, all groups of patients had increased serum levels of IL-18. The highest mean concentration of IL-18 was observed in P-TB. Serum levels of IL-18 in the patients with P-TB correlated well with the extent of disease. CONCLUSIONS: Although increased serum levels of IL-18 were not specific for TB, the increased levels may favour active TB in radiologically advanced disease where CXR findings are difficult to interpret, and sputum smears or cultures are not helpful.
