A trial of antigen prepared from Ascaris lumbricoides in the complement-fixation test for pulmonary tropical eosinophilia and for filariasis is described. No significant difference was observed between this antigen and that prepared from Dirofilaria immitis.

Pulmonary regurgitation after repair of tetralogy of Fallot has always been an important issue for pediatric cardiac surgeons. Some of the patients may need pulmonary valve replacement in the future. Conventional prosthesis valves were seldom custom made for the pulmonary valve and were often inadequate to use because of variable age and size of these patients. Through evolution of techniques, ...

BACKGROUND Tuberculosis (TB) mortality declined in the northern hemisphere over the last 200 years, but peaked during the Russian (1889) and the Spanish (1918) influenza pandemics. We studied the impact of these two pandemics on TB mortality. METHODS We retrieved historic data from mortality registers for the city of Bern and countrywide for Switzerland. We used Poisson regression models to q...

BACKGROUND Tuberculosis (TB) is one of the most ancient diseases of mankind. Despite newer modalities for diagnosis and treatment, unfortunately, people are still suffering, and TB is among the top 10 killer infectious diseases in the world. TB is a devastating disease due to its rapid transmission and high rate of mortality causing around 1.8 million deaths annually. This study was conducted t...

Coccidioidomycosis is a pulmonary infection caused by the dimorphic fungi Coccidioides immitis and Coccidioidomycosis posadasii. This disease is endemic to the southwestern United States and has a predilection for immunocompromised patients. Diabetes mellitus has been shown to be a strong risk factor for acquiring this infection in these states. Most cases are asymptomatic or present with mild ...

Aim and objectives To study the outcome of pulmonary tuberculosis patients on category I and category II DOTS. Material and methodThe present study was carried out in the department of Pulmonary Medicine, Guru Gobind Singh Medical College and Hospital Faridkot, Punjab from April 2015 to November 2016 on pulmonary TB patients registered under category I and category II DOTS. Detailed history inc...

Central haemodynamics in 23 patients with mitral stenosis and 7 control subjects were compared with the results of regional lung perfusion studied by (133)Xe, pulmonary scintigraphy with (99)mTc-labelled macro-aggregates of albumin, and regional ventilation by (133)Xe.A close correlation was found between both methods assessing regional pulmonary perfusion, i.e. pulmonary scintigraphy and (133)...

T HE auscultatory and phonocardiographic characteristics of ventricular septal defects have been the subject of several studies,'-5 none of them dealing specifically with the features of small defects. The present study represents an attempt to define the phonocardiographic pattern of ventricular septal defect with a small left-to-right shunt and normal pulmonary artery pressure. It was hoped t...

An unusual case of a one-day-old infant with significant left ventricular outflow obstruction produced by a pedunculated fibroma is described. The clinical findings were indistinguishable from severe valvular or subvalvular aortic stenosis. The tumor was difficult to detect by echocardiography. It produced an echo-free widening of the left ventricular outflow tract. Left ventricular cineangiogr...

Fifteen patients (median age 8.5 years) with fixed right ventricular outflow tract obstruction were evaluated by two-dimensional echocardiographically directed continuous wave Doppler ultrasound within 24 hours of cardiac catheterization. Pulmonary artery blood velocity measurements were determined from a real time spectral display of pulmonary artery flow profile and converted to pressure drop...
