conclusions although treatment of ec in the present study had considerable success in the short-term follow-up, it should be noted, due to the unknown of the exact cause, no specific treatment or protocol has still been identified. introduction exfoliative cheilitis (ec) is a rare chronic inflammatory condition affecting the vermillion border of the lips and characterized by excessive productio...
Chronic transplant dysfunction (CTD) is the predominant cause of late graft failure. The common histopathological feature in all transplanted organs is intimal hyperplasia accompanied by organ specific lesions. The knowledge about CTD is incomplete, and there is no therapy to prevent or treat it. This review describes the current knowledge on the etiology of CTD, with emphasis on kidney transpl...
Recent histopathology studies suggest the presence of meningeal inflammation in patients with multiple sclerosis (MS) that might be associated with subpial cortical demyelination and a rather worse disease course.1 Although a radiologist is not a pathologist, diagnostic neuroradiology aims to visualize and to detect almost every (subtle) pathological feature of a disease to its full extent. To ...
Netherton syndrome is a very rare disorder characterized with icthyosis, atopy, bamboo hair and intermittant aminoaciduria. The specifity of clinical and histopathological features of netherton syndrome is low in neonates and young infants who presents with predominating erythrodermia. Being the youngest infant presenting with the symptoms of infantile asthma we found it worth to report a six m...
برای مقاوم سازی سیستم بازشناسی گفتار در برابر عوامل مزاحم محیطی (نویز جمع شونده، اثر اعوجاج کانال انتقال و نویزهای گذرا) سه ایده کلی وجود دارد: 1- استخراج ویژگی های مقاوم(robust feature extraction) 2- بهبود کیفیت بردارهای بازنمایی (feature enhancement) 3- اصلاح مدل بازشناسی صوتی (acoustic model compensation) در ایده اول سعی می شود تا از ویژگی ها و پارمترهایی از سیگنال گفتار برای ساخت بر...
This paper presents an expert system for differential diagnosis of erythemato-squamous diseases incorporating decisions made by three classification algorithms: nearest neighbor classifier, naive Bayesian classifier and voting feature intervals-5. This tool enables doctors to differentiate six types of erythemato-squamous diseases using clinical and histopathological parameters obtained from a ...
Application of Machine Learning Techniques to Differential Diagnosis of Erythemato-Squamous Diseases
This paper is about the implementation of a visual tool for Differential Diagnosis of Erythemato-Squamous Diseases based on the classification algorithms; Nearest Neighbor Classifier (NN), Naive Bayesian Classifier using Normal Distribution (NBC) and Voting Feature Intervals-5 (VFI5). This tool enables the doctors to differentiate six types of ErythematoSquamous Diseases using clinical and hist...
A 78 year old man underwent aortic valve replacement because of acute aortic regurgitation and intractable heart failure. At operation the intact commissure between the left and right coronary cusps of a grossly normal aortic valve was found to have separated from the aortic wall. Histopathological examination of the surgical specimen showed that the site of separation was an atheromatous plaqu...
Villous atrophy, changes in the surface epithelium, mucosal thickening, and glandular hypertrophy were a feature of all the mucosal biopsies from the small intestine obtained from eight coeliac children. No histological differences were observed between the children previously treated with intermittent gluten-free diets and the untreated children. Serial biopsy studies were carried out on one c...
Adenoma malignum is a rare variant of cervical adenocarcinoma. A woman of 26 years with complains of profuse mucoid discharge per vaginum on speculum examination per vaginum showed multiple cauliflowers like growth hanging within the introitus. Punch biopsy gave a report of endocervical glandular polyp with squamous metaplasia. On excision, the mass was found to arise from the cervix and extern...
