Ultrasonography is the primary imaging tool for a patient considered to have an ovarian cyst. On a sonogram, simple ovarian cysts have a uniformly thin, rounded wall and a unilocular appearance that is either hypoechoic or anechoic. They usually measure 2.5-15 cm in diameter, and posterior acoustic enhancement (a hyperechoic area) may be visible deep to the fluid-filled cyst. Most commonly, the...

Background: Esophageal carcinoma is one of the most lethal gastrointestinal (GI) malignant tumors worldwide.  The disease is known to have a high incidence in northern Iran; however, its condition in the South is not much clear. Objective: In this retrospective study we investigated the epidemiology and time trends of esophageal carcinoma in Fars Province, South of Iran. Methods: In a retrospec...

Pulmonary hydatid cysts in children are a significant public health problem in Tunisia. While hepatic cysts are the most common in adult pathology, the lung is the number one location for hydatid cysts in children which causes a serious problem due to lack of standardized therapeutic strategy. We reported our experience in diagnosis and management of pulmonary hydatid cysts in a pediatric depar...

background: chemokine receptors have been shown to play an important role in the development and metastatic spread of various malignancies. in this study, the gene expression profile of some key chemokine receptors involved in metastasis has been investigated in esophageal and breast cancer cell lines.   methods: in a descriptive study, gene expression profile of ccr1, ccr6, ccr7, ccr9, cxcr1, ...

background: in northeastern iran there is an area of high incidence of esophageal cancer which is populated by residents of turkmen ancestry. several environmental risk factors for esophageal cancer have been proposed, but the roles of familial and genetic factors have not been studied extensively in the turkmen population. materials and methods: we evaluated the importance of familial risk fac...

leiomyoma is a rare esophageal tumor that constitutes less than 1% of esophageal malignancies. it should be removed when diagnosed even if asymptomatic. this study presents two cases of esophageal leiomyoma in 38 and 62 years old men who presented with dysphagia and evaluated for diagnosis and location of related tumors. patients were clinically examined and upper gastrointestinal endoscopy, ch...

Cysts which originated from embryonal remnants are often observed in the cervical region. Among these cysts, branchiogenic cleft cysts and thyroglossal cysts are most commonly encountered. Parathyroid cysts and cervical thymic cysts are known to be a rare entity. Reviewing the world literature of the latter two, only a few reports were noted. There is, in addition, some confusion in terminology...

MR imaging has improved the detection and characterization of cysts arising in the ovaries. Although they are less common, cysts also can develop in the endocervical glands (nabothian cysts), labia (Bartholin’s cysts), vaginal wall (Gartner’s cysts), and broad ligament (paratubal cysts). Findings on pelvic MR imaging were reviewed to determine the preyalence and MR features of gynecologic cysts...

Background: Giardia lamblia is the most frequent human intestinal protozoan worldwide. Diagnosis of G. lamblia by microscopic examination of stool is common, but ELISA & IFA methods have been used in research and epidemiological studies recently. To produce polyclonal antibodies for designing ELISA & IFA kites molecular and genomic studies (PCR and parasitic culture) as well as other epidemiolo...
