BACKGROUND Rapid and effective diagnosis of multidrug-resistant tuberculosis (MDR-TB) is an essential component of global tuberculosis (TB) control, but most MDR-TB cases are still not diagnosed. OBJECTIVE To assess whether patient sputum bacterial load can be used to identify patients at increased risk of MDR-TB. METHODS We used a case-control study and multivariable logistic regression mo...

The mechanical elongation of a finite gold nanowire has been studied by molecular dynamics simulations using different semiempirical potentials for transition metals. These potentials have been widely used to study the mechanical properties of finite metal clusters. Combining with density functional theory calculations along several atomic-configuration trajectories predicted by different semie...

INTRODUCTION Extra pulmonary TB can be encountered in various organ systems, like lymph nodes, serous cavities, genitourinary tract, skeletal. Musculoskeletal TB can cause significant functional impairment. The clinical symptoms are variable, pain and swelling being common symptomatology. Investigations for suspected cases include radiological imaging, histopathological examination, bacteriolog...

INTRODUCTION Tuberculosis of calcaneum is a rare entity. Osteoarticular tuberculosis of foot is uncommon and that of calcaneum is very rare. In children, diagnosis is often delayed as clinical presentation is non-specific and awareness is low due to its rare presentation. Also pediatric tuberculosis has traditionally received a lower priority than adult TB in National TB programmes. CASE PRES...

Tuberculosis (TB) is a global public health problem endemic to Morocco. While extrapulmonary TB uncommonly presents in osteoarticular anatomic locations, tarsal or metatarsal osteitis can occur when TB presents in the tarsal bones. Clinical symptoms are often insidious causing a delay in diagnosis that may lead to bone destruction. While diagnosis can be guided by X-ray imaging, bacteriologic a...
