Introduction:Most metastatic lymph nodes from head and neck malignancy are solid. Cystic nodes are found in 33% - 61% of carcinomas arise from Waldeyer’s ring, of which only 1.8% - 8% originate are from the nasopharynx. Some cystic cervical metastases were initially presumed to be branchial cleft cyst. This case report aims to highlight the unusual presentation of cystic cervical metastasis sec...

Introduction: A hydatid cyst of the head and neck is a very rare condition, even in areas where Echinococcus infestation is endemic.   Case Report: We report a rare case of primary hydatid cyst of the right maxillary sinus in a 40-year-old man. The initial diagnosis of the presence of a cystic mass was the result of physical examination and computed tomography (CT) scan. We resected the cystic ...

background and objectives: cystic fibrosis (cf) is an autosomal recessive genetic disease.  infections in these patients gene.are  mostly  caused  by  three  bacteria:  staphylococcus  aureus ,  haemophilus  influenza and  particularly  pseudomonas aeruginosa .  carbapenems including antibiotics are used to combat infections with pseudomonas aeruginosa . in recent years, carbapenems resistant s...

background cystic fibrosis is a complex progressive disease which assessing its progression and severity is essential. for this purpose there are scoring systems available to evaluate the disease severity. objectives the aim of the present study was to determine the clinical status of cf patients using shwachman score system in the pediatric pulmonary ward of masih daneshvari hospital. patients...

Background: Echinococcosis is a zoonotic parasitic disease caused by the larval stage of Echinococcus granulosus. Several native and recombinant antigens, derived from different stages of E. granulosus life cycle, have been used for vaccine trials. In vitro reared adult worms are good candidates for vaccination as they do not produce fertile egg/s and do not have any risk of contamination for r...

Gastric duplication cyst (GDC) in an adult can have several clinical presentations. A review of the literature showed previously reported cases of GDC presenting as pancreatic pseudocyst or with greatly raised concentrations of carbohydrate antigen 19-9 (CA 19-9). It is often difficult to discriminate GDC from pancreatic cystic tumour, in particular pancreatic mucinous cystadenoma, in which con...

A 57-year-old woman with a past history of serous ovarian cystadenoma was admitted to hospital complaining of progressive abdominal bloating for the last six months. Physical examination revealed an increase in abdominal perimeter. The rest of the physical examination was normal. Alkaline phosphatase and gamma-glutamyl-transpeptidase were marginally raised, while the rest of the liver function ...

PURPOSE To investigate modifications of ocular surface and lens transparency in patients with cystic fibrosis in relation to the stage of digestive insufficiency. METHODS Forty consecutive patients with cystic fibrosis and 24 age- and sex-matched healthy volunteers were examined. The tear tests (Schirmer's basic test, tear film break-up time) and conjunctival exfoliative cytology (CC) were us...

klossiella muris is ordinarily nonpathogenic, although in heavy infections the kidneys may have minute grayish necrotic foci over their entire surface and the epithelium of the infected kidney tubules may be destroyed. for histopathological diagnosis of klossiella muris infection, kidneys of 24 mice were studied that klossiella in various stages of development were observed in the renal tubules...
