SURGICAL AND RADIOLOGIC ANATOMY

To investigate the morphometry of patellar tendon with magnetic resonance imaging (MRI) and to reveal the relation between patellar tendon properties and anterior knee pain (AnKP). Twenty-three patients with AnKP and nine healthy individuals were included in the study. Patients with knee anomaly that may cause AnKP were excluded from the study. The patellar tendon examination was performed on sagittal and coronal sections of MRI. Freehand technique was used to frame the area of tendon and calculations were done by generic software. There were 23 patients in AnKP (+) and 9 individuals in AnKP (-) group. The morphometric results were not different among groups (p = 0.2). Higher body mass index was correlated with increased patellar tendon surface area in women (R (2) = 0.37). Patellar tendon length, thickness and surface area do not seem as a significant parameter to explain the aetiology of AnKP. Given the well-defined role of patellar tendon to support knee kinetics, the clinical value of tendon morphometry is to be determined

JOURNAL OF CLINICAL AND ANALYTICAL MEDICINE

Aim: The aim of the study was to investigate the effect of melatonin on the renal injury resulting from radiocontrast media and myoglobinuria in male Wistar albino rats. Material and Method: 50% glycerol at equal amounts was intramuscularly administered to both hind legs of all animals under ether anesthesia at the dose of 10 mg/kg. Three hours later, the groups were administered the following: Group I (number: 7): Iopromide(Ultravist -300 (R)) at the dose of 2 ml/kg (intracardiac); Group II (number: 7): Iopromide(Ultravist -300 (R)) and intraperitoneally administered Melatonin at the dose of 10 mg/kg (Melatonin was dissolved in 7.5% absolute ethanol and further dilutions were made in saline.); and Group III (number: 7): 2 ml/kg of sterile physiologic saline (Control group). The levels of Uurea, Ccreatinine and Ccystatin C were studied on the blood samples collected. The renal samples were evaluated by 2two distinct pathologists who did not know the protocol. Results: There was no difference in the values of Creatinine and cystatin c between Groups 2 and 3 (p=0.9; 0.2). Discussion: In conclusion, we evaluated the possible prevention of contrast-induced oxidative stress in the kidney with using melatonin. However, additional clinical studies are needed to evaluate the role of preventive melatonin treatment in humans

Ketotifen ameliorates development of fibrosis in alkali burns of the esophagus

WOS: 000223007900008PubMed ID: 15108014An experimental study was performed to investigate the efficacy of ketotifen, which is a mast cell stabilizer and histamine H-1-receptor antagonist, on the prevention of stricture development after esophageal caustic injuries in the rat. Caustic esophageal burn was created by applying 37.5% NaOH to the distal esophagus. Forty rats were divided into four equal groups. Group A (sham) animals were uninjured. Group B rats were injured but untreated. Group C rats were injured and received ketotifen (1 mg/kg/day) via the oral route. Group D rats were injured and received ketotifen (1 mg/kg/day) via the intraperitoneal route. Efficacy of the treatment was assessed on day 28 by measuring the stenosis index and histopathologic damage score and biochemically by determining tissue hydroxyproline content. The stenosis index in group B (0.93+/-0.22) was significantly increased compared with group A (0.39+/-0.06, p <0.05), group C (0.42+/-0.09, p <0.05), and group D (0.35+/-0.07, p <0.05). The hydroxyproline level (mug/mg wet tissue) was significantly increased in group B (1.31+/-0.08, p <0.05) compared with group A (0.69+/-0.16, p <0.05), group C (1.06+/-0.16, p <0.05), and group D (0.95+/-0.12, p <0.05). In group B the histopathologic damage score was significantly higher than in groups C (p <0.05) and D (p <0.05). There was no significant difference between group C and group D in terms of all parameters evaluated. Treatment with ketotifen decreased tissue hydroxyproline levels, histological damage, and the stenosis index. We conclude that ketotifen has a preventive effect in the development of fibrosis in an experimental model of corrosive esophagitis in rats

Co-existence of gastrointestinal stromal tumors with malign epithelial tumors: A report of two cases

Aim: To emphasize the importance of a detailed observation for incidental simultaneous tumoral masses during surgery for gastrointestinal stromal tumors (GISTs) at any location in the gastrointestinal system. Case presentations: Case 1: a 39 years old female patient with an esophageal squamous cell carcinoma and a synchronous small intestinal GIST discovered incidentally during esophagectomy. Case 2: a 73 years old female patient with a gastric GIST and a synchronous colorectal cancer detected incidentally during gastrectomy. In both cases, immunohistochemical examinations of the resected specimens confirmed the coexistences of GISTs and epithelial malignancies. Conclusion: The coexistences of GISTs with epithelial tumors have been increasing in recent years. In any case of a GIST or gastrointestinal adenocarcinoma, the surgeon should be alert to recognize a possible coexistent tumor with different histological origin
