Abstract

The aim of this study was to find out if bronchoalveolar lavage (BL) is better than gastric lavage (GL) or sputum (SP) examination for isolation of Mycobacterium tuberculosis in childhood pulmonary tuberculosis. The study included a group of 30 children with suspected pulmonary tuberculosis, aged 6 months to 18 years. Gastric lavage was done on 4 consecutive mornings after overnight fast. Sputum was examined in 12 patients older than 10 years, (4 consecutive samples). BL was performed on the same day as the last GL and SP, using a rigid bronchoscope. Specimens were examined for the existence of BL acid fast bacilli (AFB) and culture for Mycobacterium tb. Out of 30 cases, Mycobacterium tb was grown in 13 BL sampies (43.33%), and in 10 GL samples from the same patients (33.33%). Comparative analysis of microbiological samples of sputum and bronchoalveolar lavage fluid in 12 children showed that 6 patients had SP+ cultures and 6 patients had SP-cultures of Mycobacterium tb. All SP+ patients where also BL+, but 1 SP- patient was BL+. Smear examination of BL fluid samples was positive for AFB in 10 patients with positive cultures for Mycobacterium tb. The results of our study indicate that BL examination is better than GL and SP exa...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
