OBJECTIVE To determine the effects of respiration on the size of lung cysts by comparing inspiratory and expiratory high-resolution CT (HRCT) scans. MATERIALS AND METHODS The authors evaluated the size of cystic lesions, as seen on paired inspiratory and expiratory HRCT scans, in 54 patients with Langerhans cell histiocytosis (n = 3), pulmonary lymphangiomyomatosis (n = 4), confluent centrilo...

We report two cases of hepatobiliary cystadenoma. Case 1. A 58-year-old male presented with dull abdominal pain and recurrent jaundice. Abdominal echo revealed biliary tracts dilatation; ERCP revealed amorphous filling defect inside the dilated CBD, a cystic tumor in the left lobe communicated with bile duct was disclosed by MRI/MRCP. He received left lobectomy and microscopic findings proved h...

PURPOSE The purpose of the present study was to analyze the clinical characteristics and complications of patients with mesiodens. PATIENTS AND METHODS Using the radiographic reviews of patients who visited Seoul National University Dental Hospital from January 2005 through January 2008, 919 patients were identified as having mesiodens (total 1,200 mesiodentes). The number, location, position...

In patients with cystic fibrosis, most treatments addressing the underlying basic defect are mutation or mutation class specific. These treatments are disease modifying if they lower the year to year change in lung function. We therefore calculated the current loss of lung function, measured by year to year change in forced expired volume in 1s in 11,417 patients included in the European Cystic...

BACKGROUND Tiotropium is a once-daily, long-acting anticholinergic bronchodilator with the potential to alleviate airway obstruction in cystic fibrosis. Our objective was to evaluate the efficacy and safety of 2.5 and 5 µg once-daily tiotropium delivered via the Respimat Soft Mist Inhaler vs. placebo in people with cystic fibrosis. METHODS This phase 2, 12-week, randomized, double-blind, plac...

Periventricular leukomalacia is an important complication of hypoperfusion of the brain in immature newborn infants. In a real-time ultrasound study with frequent scanning of 120 infants of birth weight less than 1,501 g, hemorrhagic periventricular leukomalacia was observed in nine (7.5%), and in five of these infants subsequent development of cystic degeneration was noted. The overall inciden...

background: cystic fibrosis (cf) is a common autosomal recessive disorder that affects many body systems and is produced by mutations in the cystic fibrosis transmembrane conductance regulator (cftr) gene. cf is also the most frequently inherited disorder in the west. the aim of this study was to detect the mutations in the cftr gene in two iranian families with cf. methods: after dna extractio...

background: anaphylactic reactions, such as urticaria, edema, respiratory symptoms, and anaphylactic shock often complicate the course of cystic echinococcosis (ce). methods: to investigate the role of the ige immunoreactive antigen 5 (ag 5) in the sero-positive patients with ce, we determined n-terminal of 57 kda subunit of ag5 responsible for ige and c-terminal of this active antigen related ...
