cystic fibrosis is an inheritant autosomal recessive disease. it is associated with mutations in cystic fibrosis trans regulator gene (cftr) and has different presentations.we report two 2 month old female patients, products of a twin delivery presented with anemia, edema, hypoalbuminemia and pneumonia.after some work ups, diagnosis of cystic fibrosis was confirmed. this is an uncommon and inte...

adenoid cystic carcinomas are deceptive malignancies that show slow growth and local invasion with recurrences seen many years after diagnosis. upto 50% of these tumors occur in the intraoral minor salivary glands usually in the hard palate. buccal mucosal tumors are relatively rare. we determined the incidence of buccal mucosal adenoid cystic carcinoma by reviewing the number of reported cases...

background and objectives: this study was carried out with the objective of determining the genomic variability of p. aeruginosa strains isolated from patients suffering from cystic fibrosis or from environmental cultures collected from different locations in the unit they admitted. materials and methods: a total of 57 clinical and environmental p. aeruginosa isolates were genotyped by enteroba...

background: echinococcosis or hydatid disease is a zoonotic infection caused by larval (metacestode) stages of cestodes belonging to the genus echinococcus, family taeniidae . we aimed to subclone antigen b gene in pqe-30 plasmid, its expression, and purification. methods: we subcloned hi gene into pqe-30 expression vector. the recombinant vector was transformed into e. coli , m15 and mass cult...

Mature cystic teratoma accounts for 10-20 % of all ovarian tumors. Malignant transformation is very rare in mature cystic teratoma, its incidence being 1-2% and is commonly seen in post menopausal women with tumor size larger than 10 cm. Pre-operative diagnosis of this entity is difficult due to non specific clinical & radiological features and no specific tumor markers. Malignant change occurs...

A 31 year old man was hospitalised with general fatigue and epigastric pain. Abdominal ultrasonography, computed tomography, and magnetic resonance imaging showed a cystic lesion in the left lobe of the liver. Endoscopic retrograde cholangio-pancreatography and percutaneous trans-hepatic cholangiography revealed a localised dilatation of the intrahepatic bile duct without any obstruction. Howev...

Case 1 A newborn baby was admitted to hospital at the age of 23 days old with fever of unknown origin up to 39 ̊C. The female newborn was born by a G2P2 healthy mother by caesarean section at 40 week’s gestation in a local clinic and weighed 3600 gm. The perinatal examination was unremarkable. Delivery course was smooth. Septic workup was arranged but no definite pathogen was identified. On phys...

BACKGROUND The natural course of cytologically benign thyroid nodules remains unclear. The aim of this study was to evaluate whether ultrasonographic (US) changes are associated with changes in nodule volume during follow-up. METHODS We retrospectively reviewed over 4 years of clinical records of patients with benign thyroid nodules as confirmed by fine needle aspiration (FNA). In total, 186 ...
