Information concerning the size and shape of tunnel boring machine (TBM) debris is essential for designing efficient loading, hauling and dumping systems for TBM excavation. It is also very important in deciding how to recycle the TBM debris. However, only very limited information is available at present, and theoretical or calculation methods to estimate the size and shape are still open to di...
OBJECTIVES The study aimed at describing characteristics and outcome of tuberculous meningitis (TBM) in HIV-positive patients and comparing these parameters with those of extrapulmonary TB (TBEP) and pulmonary TB (TBP). METHODS Kaplan-Meier estimation and Poisson regression models were used to assess the mortality following TB diagnosis and to evaluate potential prognostic factors for the 3 g...
A structural study of the inclusion compound of tolbutamide (TBM) with beta-cyclodextrin (beta-CD) and hydroxypropyl-beta-cyclodextrin (HP-beta-CD) was attempted by means of 1H-nuclear magnetic resonance (1H-NMR) experiments and computer molecular modelling. To establish the stoichiometry and stability constant of the beta-CD:TBM complex, the continuous variation method was used. The presence o...
Background: In Africa, tuberculosis is generally regarded as persisting as one of the most devastating infectious diseases. The pediatric population is particularly vulnerable, with infection of the brain in the form of tuberculous meningitis (TBM) being the most severe manifestation. TBM is often difficult to diagnose in its early stages because of its non-specific clinical presentation. Of pa...
BN rats develop interstitial nephritis after immunization with rabbit, but not rat renal tubular antigen. Using RT1n rat strains that differentially express tubular antigen, we investigated the unresponsiveness of BN rats to BN tubular antigen (BN-TBM) using delayed-type hypersensitivity (DTH) responses to BN-TBM as a measure of cell-mediated immunity. Our results indicate that rat strains expr...
IntroductionHydrocephalus is one of the commonest complications of tuberculous meningitis (TBM). Endoscopic third ventriculostomy (ETV) has evolved as an alternative to shunt surgeries for obstructive hydrocephalus in TBM. It offers the opportunity to keep the patient free of foreign material and its associated complications. MethodsA retrospective study was carried out from July 2014 to June 2...
Relapsing polychondritis (RP) is a rare systemic autoimmune disease that affects cartilaginous structures. RP causes tracheobronchomalacia (TBM) by affecting the bronchial cartilage. TBM is a fatal condition characterized by excessive weakening of the walls of the trachea and bronchi. We herein report a case of a 73-year-old man who experienced sudden respiratory failure due to TBM caused by RP...
Efavirenz (EFZ) has been associated with neuropsychiatric side effects. Recently, the 8-hydroxy-EFZ (8OH-EFZ) metabolite has been shown to be a potent neurotoxin in vitro, inducing neuronal damage at concentrations of 3.3 ng/ml. EFZ induced similar neuronal damage at concentrations of 31.6 ng/ml. We investigated the effect of genotype and blood-brain barrier integrity on EFZ metabolite concentr...
INTRODUCTION Tuberculous meningitis (TBM) the most fatal presentation of tuberculosis (TB) especially in HIV-infected patients is a real diagnostic and therapeutic challenge worldwide. In Cameroon where HIV and TB are amongst the leading public health problems, the magnitude of TBM has not been defined. Therefore, the objective of this cross sectional study was to describe the presentation and ...
Tuberculous meningitis (TBM) is a common and serious complication of primary tubercular complex in preschool children in our country. Following exposure to tubercle bacilli, it takes about 6-8 weeks for a primary complex to develop(l). Six to twelve months after the primary infection, tuberculous meningitis, secondary to hematogenous spread, may occur. The commonest age group for tuberculous me...
