Introduction: This is a prospective study of 30 cases of smear positive pulmonary tuberculosis, with at least two sputum positive members of the family, seen in the respiratory clinic between January 2003 and June 2004.
Methods: They constitute the index cases who represent 3.5% of the cases of tuberculosis (n=850) and 2.9% of hospital admissions (n=1034) during the same period. Four patients were HIV positive. In the family circle, all contacts received an intradermal tuberculin test (IDTT) of 10 IU and/or a chest x-ray and/or sputum examination for AFB.
Results: Of the 601 contacts 359 (60%) had a positive IDTT with a mean diameter of 13 mm. Active pulmonary tuberculosis was found in 16 contacts giving a prevalence of 2.7% and an incidence of 4.5% (16/359). 67% of the contacts were adults aged 16-87 with a mean age of 35 years. The IDTT was positive with a mean diameter of 12.3 mm. The chest x-ray was abnormal in 40 adults (16.7%) and sputum examination confirmed pulmonary tuberculosis in 14 cases. 33% of the contacts were children (n=119) aged from 3 months to 15 years with the majority (85%) aged under 10. The IDTT was positive with a mean diameter of 12 mm and the chest x-ray was abnormal in 22 cases (18.5%). Two children of 15 years had active tuberculosis.
Conclusion: The contacts identified were treated according to the tuberculosis protocol of Senegal (2RHEZ/6EH) with the intensive phase dispensed in hospital. It is of major importance therefore to develop effective strategies of information, education, diagnosis and management for cases of infectious pulmonary tuberculosis.

Background: The global resurgence of disseminated tuberculosis (TB) after the coronavirus disease 2019 pandemic highlights the necessity of understanding host risk factors, especially in adults without human immunodeficiency virus.
Methods: We reviewed TB cases admitted to Shanghai Public Health Clinical Center from 2017 to 2022. We analyzed baseline characteristics and outcomes.

Background: Tuberculosis (TB) is a leading cause of death worldwide with over 90% of reported cases occurring in low- and middle-income countries (LMICs). Pre-treatment loss to follow-up (PTLFU) is a key contributor to TB mortality and infection transmission.
Objectives: We performed a scoping review to map available evidence on interventions to reduce PTLFU in adults with pulmonary TB, identify gaps in existing knowledge, and develop a conceptual framework to guide intervention implementation.
Introduction Tuberculosis (TB) is an infectious disease caused by . Various studies have established an association between diabetes mellitus (DM) and pulmonary TB. This study describes the prevalence of DM and its predictors in smear-positive TB patients.

The aim of this study was to analyze the associated risk factors for viral hepatitis in tuberculosis patients. This systematic review and meta-analysis adhere to the PRISMA 2020 statement, and the protocol has been registered with PROSPERO (CRD42023477241).

Pulmonary alveolar proteinosis (PAP) is a rare disease characterised by excessive accumulation of surfactant components in alveolar macrophages, alveoli, and peripheral airways. The accumulation of surfactant is associated with only a minimal inflammatory response but can lead to the development of pulmonary fibrosis. Three clinical forms of PAP are distinguished - primary, secondary and congenital.
