Tuberculosis (TB) suspect is any one who has signs or symptoms suggestive of TB (eg >2 weeks productive cough).
Definite TB is considered in patients with culture or molecular line probe assay positive for Mycobacterium tuberculosis, or in patients with at least 1 sputum smear positive for acid-fast bacilli.
TB cases are also classified based on the disease anatomical site, bacteriological results (including drug resistance), previous treatment history and patient's HIV status.
Pulmonary TB is a case of TB that involves the lung parenchyma.
Miliary TB is considered as PTB since lung lesions are also seen.
TB in the pleural effusion, mediastinal and/or hilar lymph nodes with no evidence of abnormalities in the chest x-ray are considered extrapulmonary TB.
Patients presenting with both PTB and extrapulmonary TB are classified as a case of PTB.
Individuals who have undergone gastrectomy for stomach cancer may have an added risk of developing tuberculosis (TB), according to a study from South Korea. However, this elevated risk does not appear to extend to nontuberculous mycobacteria (NTM) lung disease.
Having a high initial effusion volume of >1,000 cc was associated with an increased need for surgical intervention after treatment with chest tube thoracostomy (CTT) in patients with loculated pleural effusion, according to a study presented at the APSR 2017 Congress.
Metformin may improve survival during tuberculosis (TB) treatment in patients with diabetes mellitus—a condition which particularly carries an increased risk of adverse TB treatment outcomes, a study has found.
Statins appear to have a dose-dependent association with the risk of tuberculosis (TB), with a nationwide population-based study showing that statin users have 47 percent lower incidence of TB compared with nonusers.
Patients treated with tumour necrosis factor (TNF)-α antagonists may be at a greater risk of tuberculosis (TB), although the biological mechanism underlying this association needs to be elucidated, according to a meta-analysis.
Lowering the dosage of aminoglycosides guided by therapeutic dose monitoring (TDM) may reduce aminoglycoside-related hearing loss, without compromising its efficacy against multidrug resistant tuberculosis (MDR-TB), a recent study suggests.
The placement of personalized inhaler technique reminder labels on dry-powder asthma inhalers may improve the retention of inhaler technique skills after training and potentially extend the benefit of the training onto asthma outcomes, according to a study.
Better clinical efficacy was observed among cancer patients with postoperative hospital-acquired pneumonia (HAP) who received prolonged infusion of the mixed preparation of the broad-spectrum β-lactamase inhibitor tazobactam and β-lactam antibiotic piperacillin (TZP) compared with those who received the traditional regimen, according to a study.
Use of vitamin D supplementation prevents acute respiratory tract infection, with individuals who are very deficient in vitamin D and those not receiving additional bolus doses benefitting the most, a recent study has found.
Fluticasone furoate is superior to mometasone nasal spray in improving several perceived sensory attributes of allergic rhinitis patients, based on a multicentre, randomised, crossover, prospective study.
