Background: Pneumonia is the main cause of death among children under five years of age particularly in developing countries. According to the WHO, there are more than 15 million cases representing 7-13% of pneumonia cases annually which necessitate hospital admission due to their severity. There is paucity of data regarding the clinical spectrum and the epidemiology of severe pneumonia from eastern part of Nepal. It is important to understand the clinical spectrum and the epidemiology of severe pneumonia at local level to better define problem and to draw inferences for management and policy formulation. Material and Methods: A hospital based retrospective observational study conducted at Department of Pediatrics and Neonatology, Nobel Medical College and Teaching Hospital, Biratnagar, Nepal. One hundred and forty four cases with a diagnosis of severe pneumonia were studied over a period of one year. All the cases from 1 month to 5 years of age fulfilling the standard WHO case definition of severe pneumonia were included in the study. A pre-designed semi-structured questionnaire was used to obtain the clinical profile and investigations. Results: A total of 144 cases were studied and analyzed. The age range was from 1 month to 5 years. The mean age of the cases was 13.56 months. Majority of the cases belonged to age group of 1-6 months 40.27% (n=58). There was a male preponderance in our study comprising 58.3% (n=84) of males and 41.7% (n=60) of females. Fever and cough were the most common symptoms present in all cases, fever being present in 95.8% (n=136) cases and cough was present in 98.6% (n=142) cases. The most common radiological finding in our study was bronchopneumonia in 27.8% (n=40) cases followed by lobar pneumonia in 24.3% (n=35) cases and interstitial pneumonia in 18.8% (n=27) cases. Complications were present in 6.9% (n=10) cases and 22.2% (n=32) of the cases had no radiological abnormalities. Among the studied symptoms and signs of severe pneumonia, hurried breathing (p<0.001), wheeze (p=0.016), refusal of feeds (p=0.001), altered sensorium (p=0.006) and previous history of acute respiratory infections showed significant association with radiological abnormalities. Conclusion: Children of severe pneumonia presenting with fast breathing, wheeze, altered sensorium, refusal of feeding and past history of acute respiratory infections showed significant association with abnormal chest radiographs.

Studies of the biology of Pneumocystis carinii (PC) are of increasing importance because this extracellular pathogen is a frequent source of severe pneumonia in patients with acquired immunodeficiency syndrome (AIDS) and is a leading cause of mortality in these patients. Immunoelectron microscopic localization of antigenic sites on the surface of PC would improve the understanding of these sites and their role in pathenogenisis of the disease and response to chemotherapy. The purpose of this study was to develop a methodology for visualizing immunoreactive sites on PC with transmission electron microscopy (TEM) using immunogold labeled probes.Trophozoites of PC were added to spinner flask cultures and allowed to grow for 7 days, then aliquots of tissue culture fluid were centrifuged at 12,000 RPM for 30 sec. Pellets of organisims were fixed in either 1% glutaraldehyde, 0.1% glutaraldehyde-4% paraformaldehyde, or 4% paraformaldehyde for 4h. All fixatives were buffered with 0.1M Na cacodylate and the pH adjusted to 7.1. After fixation the pellets were rinsed in 0.1M Na cacodylate (3X), dehydrated with ethanol, and immersed in a 1:1 mixture of 95% ethanol and LR White resin.

The article presents a clinical case of successful treatment of a patient with prolonged asthmatic status. The pathogenesis of purulent-septic and other life-threatening complications developing as a result of the above critical condition is described. The positive effect of a differentiated approach in conducting respiratory support depending on the stage of the disease is justified: at the beginning, when airway obstruction is in the foreground, and in the future, when restrictive respiratory disorders develop. When conducting respiratory support, the most reasonable methods for ensuring airway patency were selected. The necessity of neurovegetative blockade and myoplegia for the prevention of pulmonary barotrauma during respiratory support by aggressive ventilation modes and with the goal of antihypoxic protection of the brain is emphasized. During the treatment of the patient, it was confirmed that the optimal regime for obstruction of the bronchi is forced volume-cyclic ventilation of the lungs to provide the necessary minute volume of breathing, and in severe pneumonia, in the case of relief of bronchial obstruction, respiratory support is carried out in pressure control mode for better air-oxygen mixture distribution in the airways. The need for early tracheostomy and daily therapeutic fibrobronchoscopy to ensure airway patency and treat pneumonia has been confirmed.
