Primary myxomas and myxosarcomas of the lung are very rare. Stout studied in 1948 the records of Columbia University and the cases reported in the world literature and was able to collect 140 cases but there were no myxomas arising from the lung or pleura. Miller and Jackson (1954) reported a case of myxosarcoma of the lung and Barkley and Cardozo (1957) published another case of myxomatous tum...

Bronchial responsiveness to inhaled methacholine was measured four to six days before fibreoptic bronchoscopy in 22 asthmatic patients (10 smokers) and 20 control subjects (12 smokers). The asthmatic patients had a baseline FEV, greater than 60% predicted and a PD20FEV, (provocative dose of methacholine causing a 20% fall in FEV,) of 0 006-3-7 mg. The 20 control subjects had normal pulmonary fu...

The head-downwards tipped position for physiotherapy has been claimed to exacerbate gastro-oesophageal reflux (GOR) in infants with cystic fibrosis (CF). This was investigated using lower oesophageal pH monitoring during physiotherapy. Twenty-one infants (age range 1-27 months) with respiratory disorders (CF=11), undergoing lower oesophageal pH monitoring were recruited. Subjects received two p...

A 41 year old man who worked at a PVC factory and had suffered from daily cough and gradually increasing dyspnoea since July 1981 has been followed since February 1982. He had smoked one package of cigarettes daily for 20 years. The patient had worked in a PVC factory from 1974 but had an accumulated exposure to PVC dust of only about 750 days. Total dust concentrations during packing of PVC ra...

PURPOSE Small intercostal spaces and limited pleural space significantly limits the use of 12-mm stapling devices in pediatric thoracoscopic surgery. The goal of this study was to compare sealing of lung tissue by the 5-mm Ligasure (Valley Lab, Boulder, CO) device to a standard 12-mm Endo-GIA stapler (US Surgical, Norwalk, CT). METHODS Institutional Animal Care and Use Committee (IACUC) appro...

OBJECTIVE Neuroendocrine cell hyperplasia of infancy (NEHI) is a form of childhood interstitial lung disease characterized by tachypnea, retractions, crackles, and hypoxia. The aim of this study was to report and discuss the clinical, imaging, and histopathological findings in a series of NEHI cases at a tertiary pediatric hospital, with an emphasis on diagnostic criteria and clinical outcomes....

OBJECTIVES The aim of this study was to evaluate the pattern of lingual split line when performing a bilateral sagittal split osteotomy (BSSO) for asymmetric prognathism. This was accomplished with the use of cone-beam computed tomography (CBCT) and three-dimensional (3D) software program. MATERIALS AND METHODS The study group was comprised of 40 patients (20 males and 20 females) with asymme...

Objectives: We analyzed the clinical characteristics of patients with pulmonary mycobacterial disease diagnosed as coincidental pulmonary infection due to Mycobacterium species. Materials and Methods: One hundred sixty patients satisfied the diagnostic criteria of nontuberculous mycobacterial disease proposed by American Thoracic Society during the last seven years. Six patients (3.8%) were coi...

CASE REPORT A 66-year-old man with a several-month history of dysphagia and weight loss presented to a gastroenterologist and underwent upper endoscopy and biopsy. Th is revealed a moderately diff erentiated invasive adenocarcinoma in the distal third of the esophagus. He was then referred for PET-CT, which was performed 60 minutes after the injection of 540.2 MBq F-18 fl ourodeoxyglucose (FDG)...

Although theoretical models and experiments on animals exist that predict the distribution of asbestos fibres in the lung, there are few studies in man that relate to this question and they have generated contradictory results. To examine this distribution analytical electron microscopy was employed to determine the amosite fibre concentration, size, surface area, and mass in 29 circumferential...
