Background: Non-tuberculous mycobacterial (NTM) infections have been drawing interest recently because of their rising incidence not only in immunocompromised but also in immunocompetent individuals. These are underdiagnosed in India, due to the lack of awareness and a low index of suspicion. In regions endemic for tuberculosis (TB) such as India, presumptive anti-tubercular treatment (ATT) is often prescribed. Non-response of NTM to the treatment may be wrongly ascribed to multidrug-resistant tuberculosis. This emphasizes the need to correctly identify them before initiating therapy.
Case Study: We describe the case of a young, healthy female patient who developed cervical lymphadenitis and was given presumptive ATT. Microbiological examination of aspirate revealed M. fortuitum. This not only rectified the course of treatment resulting in complete cure, but also spared the patient from significant side effects of ATT. This case is an awakening call for clinicians to avoid presumptive ATT.

Drug-Resistant Bone, Joint and Spine Tuberculosis: Evolution of Diagnosis and Treatment.
Indian J Orthop

University College of Medical Sciences, University of Delhi, A10 Part B, Ashok Nagar, Ghaziabad, 201002 India.
Background: Drug resistant (DR) osteoarticular TB (OATB) is a challenge in view of it being deep seated lesion and paucibacillary disease. Case definition, investigation protocol, treatment of proven DR and those cases where DR could not be demonstrated lacks clarity and evidence. Hence, a series of studies were conducted to develop an algorithm to investigate and treat therapeutically refractory disease (TRD) or presumptive drug resistance (PDR) cases of OATB.

Department of Orthopaedics, University College of Medical Sciences and Guru Teg Bahadur Hospital, Dilshad Garden, Delhi, 110095 India.
Background: There is paucity of data on incidence and pattern of drug resistance in spinal TB. This prospective observational study was conducted to document the incidence and drug-resistance pattern among primary and presumptive resistant cases.
Methods: 59 consecutive cases diagnosed clinico-radiologically (imaging) were grouped into Group A ( = 51, primary cases) and Group B ( = 8, presumptive resistant cases) based on pre-defined criteria (INDEX-TB guidelines).
Xpert Ultra stool testing to diagnose tuberculosis in children in Ethiopia and Indonesia: a model-based cost-effectiveness analysis.
BMJ Open
July 2022
Technical Division, KNCV Tuberculosis Foundation, Den Haag, The Netherlands.
Objectives: The WHO currently recommends stool testing using GeneXpert MTB/Rif (Xpert) for the diagnosis of paediatric tuberculosis (TB). The simple one-step (SOS) stool method enables processing for Xpert testing at the primary healthcare (PHC) level. We modelled the impact and cost-effectiveness of implementing the SOS stool method at PHC for the diagnosis of paediatric TB in Ethiopia and Indonesia, compared with the standard of care.

Background And Aims: Hepatic tuberculosis (HTB) is rare and mimics neoplastic liver lesions clinico-radiologically leading to misdiagnosis and even unnecessary surgery.
Methods And Material: We analysed 43 cases of HTB diagnosed at a referral cancer centre over 10 years. Clinical details, investigations and treatment received were noted.
Tuberculosis of the spine in children - does drug resistance affect surgical outcomes?
Spine J
December 2021
Department of Orthopaedics, Bai Jerbai Wadia Hospital for Children, Parel, Mumbai 400012, India.
Background Context: The emergence of drug resistance has complicated the management of spinal tuberculosis (TB). While it is well known that the medical management of drug-resistant spinal TB is more difficult, the surgical outcomes of the same have not been studied sufficiently, particularly in children.
Purpose: To analyze the surgical outcomes in a cohort of children treated for spinal TB, and to thus assess whether drug resistant (DR) disease is associated with poorer surgical outcomes.
