Latent tuberculosis diagnostics: current scenario and review.

This review presents a comprehensive examination of the contemporary landscape pertaining to latent tuberculosis infection (LTBI) diagnostics, with a particular emphasis on the global ramifications and the intricacies surrounding LTBI diagnosis and treatment. It accentuates the imperative of bolstering diagnostic, preventive, and treatment modalities for tuberculosis (TB) to fulfill the ambitious targets set forth by the World Health Organization aimed at reducing TB-related mortalities and the incidence of new TB cases. The document underscores the significance of addressing LTBI as a means of averting the progression to active TB, particularly in regions burdened with high TB prevalence, such as India.

Maxillary sinus tuberculosis: various presentations.

Tuberculosis (TB) of the maxillary sinus is rare. We describe the clinical presentation, management and outcome in two human immunodeficiency virus (HIV) seronegative patients with histopathologically confirmed maxillary sinus TB. One of the patients who presented earlier in the course of the disease could be managed with antituberculosis treatment alone, while the other who presented late required surgical intervention as well.

Complete right lung agenesis presenting with bronchial asthma and allergic rhinitis.

A 26 year-old lady presented with episodic breathlessness, chest tightness, recurrent nasal obstruction and excessive sneezing, mainly during change of season along with opacity of the right hemithorax on chest x-ray. Further detailed work-up including spirometry, high-resolution CT scan of the thorax and fibre-optic bronchoscopy confirmed complete right lung agenesis in patients with bronchial asthma and allergic rhinitis. Complete control of symptoms was achieved with formeterol 6 μg and mometasone 200 μg (via dry powder inhaler) and intranasal fluticasone 50 μg (nasal spray) 2 puffs twice daily and oral montelukast 10 mg with levocetirizine 5 mg once daily.

Ewing's Sarcoma Presenting as Pleural Effusion.

A 20-year-old female presented to the Pulmonary Medicine Department with complaints of fever, left sided chest pain and progressive dyspnoea of four months duration. Radiological examination revealed a mass lesion with massive pleural effusion and rib erosion. Histopathology showed neoplastic cells with scanty cytoplasm, hyperchromatic nuclei and rosette formation suggestive of Ewing sarcoma.
