Background: Ovarian fibroma is the most common benign solid tumor of the ovary. The most common symptoms are abdominal discomfort and pain. Ovarian fibroids are associated with Meigs syndrome in 1% to 10% of cases. The aim of study is report of a case of Meigs syndrome Case presentation: A 65-year-old menopausal woman who complained of abdominal pain was referred to our academic hospital of Ma...
introduction retrorectal cysts are rare benign lesions which are frequently diagnosed in middle-aged females. according to their origin and histopathologic features, retrorectal cysts are classified as squamous-lined (dermoid or epidermoid) cysts, postanal gut (tailgut) cysts, and rectal duplications (enteric or enterogenous cysts, enterocystomas). described in this case report is an extremely ...
This paper proposed ovarian cancer detection in the image using joint feature extraction and an efficient Net model. The noise of input is filtered by Improved NLM (Improved Non-Local Means) filtering. deep features are extracted Deep CNN_RSO (Deep Convolutional Neural Network Rat Swarm Optimization), low-level texture ILBP (Interpolated Local Binary Pattern or Interpolated LBP). To improve red...
Endometriosis is defined as presence of endometrial tissue outside of the uterus. It is a common disorder of women in reproductive age. It is estimated to occur in ten percent iof women in this age and even more in patients with infertility and pelvic pain. Endometriosis varies in appearance from a few minimal lesions to massive ovarian endometriotic cysts that distort the tubo-ovarian anatomy ...
The use of Frozen-section during surgical procedures, gives the surgeon valuable information and guides him to perform the appropriate surgical procedure. In order to determine the accuracy of Frozen-section in gynecologic surgery, we compared the results of 172 gynecologic Frozen-section diagnosis with their final diagnosis in Mirza Kockak Khan Hospital, from 1378 to 1379. A total of 106 ovari...
BACKGROUND The traditional view of epithelial ovarian cancer asserts that all tumor subtypes share a common origin in the ovarian surface epithelium (OSE) DESIGN: A literature review was carried out to summarize the emerging understanding of extraovarian sources of epithelial ovarian carcinomas. RESULTS Historically, there were no diagnostic criteria for documenting the origin of ovarian epit...
We have used five cats to investigate the effects of two distinct visual cortex lesions on the segregation of two different texture stimuli. The ablation of areas 17 and 18 (tier I) severely impaired the segregation between textures made of line elements differing in orientation, but spared the segregation between annulus and dot textures. In contrast, the ablation of those areas receiving dire...
Background: Ovarian lesions are one of the most frequent lesions in women .The pre-operative diagnosis relies mainly on clinical and radiological findings while post-operative diagnosis is made by histo-pathological examination. With the advent of accurate imaging techniques like USG and CT scan, guided FNAC can prove to be an efficient diagnostic modality for ovarian neoplasm. Aims & Objective...
STUDY OBJECTIVE Functional ovarian lesions represent 45% of all pediatric adnexal abnormalities. Their surgical management, even if frequent, is not clear, especially in pediatric age. MATERIALS AND METHODS We retrospectively reviewed 22 pediatric patients surgically treated for functional ovarian lesions from 2000 to 2006. The following characteristics were analysed: age, size of the lesion,...
This study presents an efficient way to segment the skin cancer images. A novel method is proposed that combines colour and texture for the segmentation of skin lesions from unaffected skin region in an image. The distributions of colour and texture features provide a platform for the discrimination of skin lesions. The segmentation results are evaluated quantitatively by means of a comparative...
