Tuberculosis (TB) is a leading cause of death worldwide. It can affect any organ. However, cardiac involvement is extremely rare. Anti-TB therapy has been proved to be effective and curative in majority of TB cases except TB myocarditis, where it is found to be fatal. We describe three cases with confirmed TB with impaired left ventricular systolic function and low ejection fraction. All three cases improved clinically and left ventricular function returned to normal within a few weeks after the commencement of TB therapy...

Hemophagocytic syndrome is a life-threatening disease characterized by the uncontrolled activation of macrophages, resulting in hemophagocytosis of blood cells in the bone marrow. A 20-year-old gravida at 23-week and 5-day gestation was admitted to hospital to evaluate fever up to 104°F of unknown origin, moderate cytopenia, and elevated levels of liver enzymes. Bone marrow biopsy confirmed hemophagocytic syndrome, and polymerase chain reaction came back positive for Mycobacterium tuberculosis. Supportive care and tuberculosis treatment resulted in clinical improvement...

Tuberculosis (TB) is still endemic in many developing countries. Involvement of wrist joint is very rare, and the diagnosis is often missed. We present a case of isolated TB of the wrist, which was confirmed with intraosseous tissue histopathological examination in a 10-year-old boy. Antibacterial chemotherapy during 12 months promoted healing and good outcome.

BACKGROUND: Tuberculosis (TB) ranks as the second leading cause of deaths due to infectious diseases. Although global efforts have been made to control TB, still, this is a serious threat as Mycobacterium tuberculosis (MTB) produced resistance against both the first- and second-line drugs. The increasing incidence of multidrug-resistant, extremely drug resistant, and totally drug-resistant TB worldwide requires extra efforts to search for new anti-TB drugs. MATERIALS AND METHODS: The present study evaluated the antimycobacterial activities of Citrullus colocynthis, Calotropis procera, Ricinus communis, Capparis decidua, and Fagonia cretica plants' extracts against rifampicin-sensitive (H37Rv) and rifampicin-resistant (TMC331) strains of MTB...

INTRODUCTION: Tuberculosis (TB) and diabetes mellitus (DM) are both important health issues, and the association between DM and TB may be the next challenge for global TB control worldwide, type 2 DM (T2DM) responsible for 90% of DM cases. Persons with diabetes have a significantly increased risk of active TB, which is two to three times higher than in persons without diabetes. The aim of this study was to determine the association between pulmonary tuberculosis (PTB) and T2DM among Sudanese patients and also to determine the association between hemoglobin A1c (HbA1c) percentage in diabetic patients and development of PTB and effect of duration of T2DM in developing PTB...

OBJECTIVE/BACKGROUND: Global indices show that Nigeria has the highest tuberculosis (TB)-related mortality rate. Overdependence on Ziehl-Neelsen (ZN) smear microscopy for diagnosis and human immunodeficiency virus (HIV)/AIDS has limited control efforts. The new polymerase chain reaction-based XpertMTB/Rif (Cepheid Inc., CA, USA), which detects Mycobacterium tuberculosis and rifampicin resistance, was introduced in Cross River State in 2014. We evaluated the increment in pulmonary TB case detection following introduction of XpertMTB/Rif into the Cross River State TB control program...

OBJECTIVE/BACKGROUND: Extrapulmonary tuberculosis (EPTB), which accounts for 10%-40% of the global burden of TB, with the highest incidence in Sub-Saharan Africa, is strongly associated with human immunodeficiency virus infection. Diagnosing EPTB is challenging, and recently, there has been a concerted effort to evaluate the latest molecular diagnostics for diagnosing TB in a range of specimen types. The Xpert MTB/RIF assay (Cepheid, Sunnyvale, CA, USA) is one such technology, which simultaneously detects Mycobacterium tuberculosis and rifampicin resistance...

OBJECTIVE/BACKGROUND: There are several methods used to screen for latent tuberculosis (TB) infection (LTBI) including the QuantiFERON-TB Gold-in-Tube (QFT-GIT) and T-SPOT-TB (T-SPOT) tests. Many studies have reported the equivalence of these two methods, but it is unclear which of them is more cost effective. We investigated the age and cost issues of these tests in screening for LTBI among health-care workers. MATERIALS AND METHODS: One hundred and forty new employees during 2008-2011 in our hospital were screened using the QFT-GIT test, and 140 new employees during 2011-2014 were screened with the T-SPOT test for LTBI...

OBJECTIVE/BACKGROUND: Nontuberculous mycobacterial (NTM) species are assuming public health importance in pulmonary diseases; they are increasingly being isolated, and importantly, most NTMs do not respond to routine tuberculosis (TB) drugs. This study aimed to identify NTMs isolated from pulmonary TB cases and also determine their susceptibility to streptomycin (STR), isoniazid (INH), and rifampicin (RIF). METHODS: A total of 1755 mycobacterial isolates, obtained between August 2012 and July 2014, from 2036 smear-positive pulmonary cases were identified using polymerase chain reaction amplification of IS6110, and hsp65 gene sequencing analysis...

OBJECTIVE/BACKGROUND: Mycobacterium lepraemurium (MLM), the etiologic agent of murine leprosy, is an intracellular parasite of macrophages; the mechanism used by this bacterium to enter macrophages is not known. The fate of the MLM phagosome inside macrophages is also unknown. This study was conducted to investigate how MLM enters macrophages and to define the maturation process of MLM phagosome inside macrophages. MATERIALS AND METHODS: Peritoneal macrophages were incubated in the presence of mannan-bovine serum albumin (BSA), and antibodies to known macrophage receptors, including, anti-FcγRIII/RII (anti-CD16/32), anti-CD35 (anti-CR1), anti-TLR2, anti-TLR4, anti-TLR6, anti-CD14, and anti-dendritic cell-specific intercellular adhesion molecule-3-grabbing nonintegrin (DC-SIGN)...

BACKGROUND: Drug-resistant tuberculosis (DR-TB) continues to be a challenge in developing countries with poor resources. Despite the high prevalence of primary DR-TB, its routine screening prior to the treatment is not performed in public hospitals in Nigeria. Data regarding drug resistance and its genetic determinant among follow-up patients with TB are lacking in Nigeria. Hence, the aim of this study was to determine the prevalence and genetic determinant of drug resistance among the follow-up patients with TB in a tertiary hospital in Nigeria...

OBJECTIVE/BACKGROUND: Mycobacterium cosmeticum, first described in 2004, was recovered from a patient undergoing a cosmetic procedure. Subsequently, this species was associated with an outbreak in a nail salon. In all cases, the isolates were susceptible to all antibiotics tested. Recently, however, we recovered a strain of M. cosmeticum from the Chesapeake Bay, resistant to 11 of 14 antimicrobials. The objective of this work was to present our findings on the resistance and susceptibility of this isolate to various antibiotics...

BACKGROUND: Port-site infection (PSI) is a prevailing, chronic, nagging, treatment refractory complication of laparoscopic surgery (LS). It neutralizes the advantages of minimally invasive surgery and increases morbidity, treatment cost of patient, leading to loss of confidence on operating surgeon. PSIs are preventable with appropriate preoperative, intraoperative, and postoperative measures. Atypical mycobacterium is most commonly associated with nonhealing postlaparoscopic wound infections, causing outbreaks or sporadic cases worldwide...
