Rats were divided into three groups: sham, VCM and VCM plus erdosteine. VCM was administrated intraperitoneally (i.

Intestinal atresia with segmental musculature and neural defect.

Background/purpose: The aim of this study was to investigate the possible etiologic factors of small bowel atresia and to detect the prognostic role of adequate resection and tapering in postoperative morbidity and mortality.

Methods: Intestinal resection specimens were obtained from 10 patients with jejunoileal atresia and 3 control subjects without any gastrointestinal disease. Intestinal specimens taken from 2-cm and 4-cm proximal sides of atresia, atretic segment, and 1-cm and 2-cm distal sides of atresia were stained with Masson trichrome and H&E.

Squamous cell metaplasia of the nasopharyngeal epithelium and its association with adult-onset otitis media with effusion.

Conclusion: The common association between adult-onset otitis media with effusion (AO-OME) and squamous cell metaplasia (SCM) of the epithelium of Rosenmüller's fossa, which is near the Eustachian tube orifice, implies the predictive role of metaplasia, which probably compromises the drainage function of the middle ear.

Objective: To determine the effects of nasopharyngeal epithelial changes (SCM) on AO-OME. AO-OME is a multifactorial and insidious disease that may necessitate detailed investigation, i.

Leptin expression in the testicular tissue of fertile and infertile men.

There have been several studies about the presence of leptin in serum and testicular tissue, and none of them compares the leptin expression in the testicular tissue of fertile and infertile men. We assessed the presence of leptin expression in the testicular tissue of fertile and infertile men. 20 azoospermic infertile men were included in the study.

Incidence of unexpected pathology in routine adenoidectomy specimens.

Objective: The aim of this study was to determine the incidence of unexpected pathologies in adenoidectomy specimens and necessity for histopathologic evaluation of adenoid tissue.

Materials And Methods: All patients younger than 16 years who underwent routine adenoidectomy were reviewed. Patients were excluded if the primary surgery was other than routine adenoidectomy such as nasopharyngeal biopsy for suspicion of malignancy or other pathology.

The effect of tumor invasion patterns on pathologic stage of bladder urothelial carcinomas.

The aim of this study was to investigate tumor invasion pattern, its heterogeneity and association with histopathological features and stage in invasive urothelial carcinoma of the bladder. We studied 62 cases of invasive urothelial carcinoma of the bladder. World Health Organization (WHO) 1973, WHO/ISUP 1998 and WHO 1999 systems were used for tumor grading.

Absence of pulmonary uptake of Tc-99m methylenediphosphonate in alveolar microlithiasis.

Pulmonary alveolar microlithiasis (PAM) is a rare disease of unknown etiology characterized by accumulation of calcific concretions in the alveolar spaces. The paper reports a case of PAM in a 56-year-old male. The patient had persistent dry cough, and gradually progressive dyspnea on exertion.

Vascular wall damage in rats induced by organophosphorus insecticide methidathion.

We have examined the effect of subchronic methidathion (MD) administration on vascular wall damage. The experimental groups were: control group and rats treated with 5 mg/kg MD. The MD group was given MD by gavage for 5 days a week for 4 weeks at a dose level of 5 mg/kg per day by using corn oil as the vehicle.

A case of condyloma acuminatum treated successfully with low-dose isotretinoin and interferon.

The treatment of condyloma acuminatum may be problematic in clinical practice. We present a 27-year-old man with condyloma acuminatum who was treated successfully with a combination therapy of isotretinoin and interferon-alfa-2a. In the previous reports of combination therapy, isotretinoin has been given in a dosage of 1 mg/kg/day.

Synchronous primary adenocarcinoma and gastrointestinal stromal tumor in the stomach: a report of two cases.

Synchronous occurrence of epithelial and gastrointestinal stromal tumors (GISTs) in the stomach is uncommon. This association has often been detected incidentally on gastric mucosa or serosa, or occasionally intramurally, at surgery or gastroscopy for other reasons. Various hypotheses have been proposed regarding this simultaneous development, and it is not known whether or not such an association is a simple incidental coexistence or whether the two lesions are connected by a causal relationship.
