Tuberculosis is no longer confined to developing nations; it persists as a significant contributor to illness and death on a global scale. The subtle clinical manifestation and association with human immunodeficiency virus infection poses obstacles for early diagnosis and management. Tuberculosis manifesting at extrapulmonary sites is relatively rare. We herein present the case of a 26-year-old patient from Cameroon with a history of pleuropulmonary tuberculosis treated in 2008, who had been taking pre-exposure prophylaxis (PrEP). The patient presented with right shoulder pain of an inflammatory type. The case was diagnosed as tuberculous osteomyelitis of the scapular spine, complicated by a deltoid abscess. Diagnosis was confirmed using computed tomography and the MTB/RIF GeneXpert test on the abscess puncture. This rare form of tuberculosis with an exceptional site revealed a HIV infection with profound immunosuppression. The patient was initiated on anti-tubercular treatment according to Moroccan recommendations. Full article

Background: Tuberculosis remains one of the biggest global public health problems today. The objective of this study was to evaluate the diagnostic methods, clinical outcomes, patient compliance, and mortality rates in patients diagnosed with extrarespiratory tuberculosis. Methods: 105 cases of extrarespiratory tuberculosis were analyzed over a five-year period (2018–2023). Data from medical records were reviewed and processed. Diagnostic methods included Ziehl–Nielsen staining, Löwenstein–Jensen cultures, GeneXpert, and histopathological analysis. Diagnosis was supplemented by a specialist organ examination and, in cases with concurrent pulmonary involvement, by a chest X-ray and sputum examination. For negative cases, a probabilistic diagnosis was made. Results: Most patients presented pleural TB (38%), osteo-articular TB (26.67%), and ganglionary TB (19%). Patients were mostly men (56.19%), in the 18–40 years-old category (40%), and lived in rural areas (61%). In total, 94.29% were newly diagnosed and most observed comorbidites were chronic smoking (11.37%), chronic lung diseases (10.20%), and malnutrition (9.02%). Moreover, 68% had a negative microscopic examination, while 55% had negative cultures on Löwenstein–Jensen. Conclusions: This study highlights the importance of a multi-modal approach to diagnosing extrarespiratory tuberculosis, especially in negative bacteriological and histopathological results. Imaging, combined with clinical and epidemiological data, is critical for a probabilistic diagnosis. GeneXpert proved useful in difficult cases. This study emphasizes the need for a comprehensive diagnostic strategy to effectively manage extrarespiratory tuberculosis. Full article

Background: Pediatric osteoarticular tuberculosis (TB) remains a significant global health challenge, particularly in resource-limited settings, where delayed diagnosis and treatment frequently lead to severe long-term complications. Despite advancements in TB control, skeletal TB in children is often misdiagnosed due to its non-specific clinical presentation, contributing to poor outcomes such as joint deformities, growth disturbances, and chronic pain. The complexity of diagnosing osteoarticular TB is further exacerbated by the limited sensitivity of conventional diagnostic tools and the overlap with other musculoskeletal conditions. This study seeks to evaluate the impact of early detection and multidisciplinary management on treatment outcomes in pediatric patients with osteoarticular TB. Methods: A retrospective review was conducted at the Pediatric Orthopedics Department of the “Grigore Alexandrescu” Children’s Hospital in Romania from 2009 to 2023. Case data included clinical, imaging, and microbiological findings, and treatment outcomes in children aged 0–18 years diagnosed with tuberculous osteomyelitis. Results: The study identified varied clinical presentations, with delayed diagnosis often linked to misinterpretation of symptoms as non-TB infections. Multimodal diagnostic approaches combining imaging, microbiological testing, and histopathology improved diagnostic accuracy. Early surgical intervention alongside anti-TB therapy proved effective in reducing long-term complications. Conclusions: Timely, accurate diagnosis and multidisciplinary treatment are critical to improving outcomes in pediatric osteoarticular TB. Vaccination status and comprehensive diagnostic tools significantly influence disease progression and treatment success. The study underscores the need for enhanced screening and diagnostic methods to prevent delays in treatment. Full article

According to the World Health Organization (WHO), around 1 million children worldwide are diagnosed with tuberculosis each year. The Bacillus Calmette–Guérin (BCG) vaccine has been used around the world for over 100 years. The complications of the BCG vaccination can occur in about 0,06% of children and include local or systemic adverse reactions. Due to the close analogy between the vaccine strain and other species of the Mycobacterium tuberculosis complex (MTBC), molecular methods are recommended for differential diagnosis of Vaccine adverse events (VAE) after BCG. The ability to quickly and specifically identify BCG is important in view of different treatment regimens. The aim of the study was to assess the usefulness of genetic testing for Mycobacterium bovis BCG in the paraffin-embedded specimens’ methods. We describe two cases of VAE in immune-compromised children presenting with osteoarticular changes that had been clinically suspected of tuberculosis and led to molecular identification through GeneXpert, GenoType MTBC, and Spoligotyping. Results: Mycobacterium bovis BCG was detected in osteoarticular changes embedded in paraffin block of two patients. Conclusion: Genetic tests using paraffin-embedded materials allow for quick identification and differential diagnosis of patients with Tuberculosis and VAE after BCG. This is an important issue, especially in cases where the tissue has only been submitted for histopathological examination without microbiological diagnostics for tuberculosis. Full article

The optimal treatment for osteoarticular infection due to multidrug-resistant tuberculosis strains (MDR-OATB) remains unclear. This study aims to evaluate the diagnosis, management and outcome of MDR-OATB in France. We present a case series of MDR-OATB patients reviewed at the French National Reference Center for Mycobacteria between 2007 and 2018. Medical history and clinical, microbiological, treatment and outcome data were collected. Twenty-three MDR-OATB cases were reported, representing 3% of all concurrent MDR-TB cases in France. Overall, 17 were male, and the median age was 32 years. Six patients were previously treated for TB, including four with first-line drugs. The most frequently affected site was the spine (n = 16). Bone and joint surgery were required in 12 patients. Twenty-one patients (91%) successfully completed the treatment with a regimen containing a mean of four drugs (range, 2–6) for a mean duration of 20 months (range, 13–27). Overall, high rates of treatment success were achieved following WHO MDR-TB treatment guidelines and individualized patient management recommendations by the French National TB Consilium. However, the optimal combination of drugs, duration of treatment and role of surgery in the management of MDR-OATB remains to be determined. Full article

There has been a major resurgence of tuberculosis (TB) and drug-resistant tuberculosis in the last few decades. Although it has been brought under control in most Western countries, it is still a major cause of death in endemic regions like India. Osteoarticular tuberculosis (OA TB) forms a small proportion of the total cases of tuberculosis. Perceptions and practices of orthopedic surgeons are entirely different in endemic and non-endemic regions around the world, due to the vast difference in exposure. Literature from endemic areas puts stress on clinico-radiological diagnosis and empirical anti-tubercular treatment (ATT). Such practices, although non-invasive, simple to implement, and economical, carry a significant risk of missing TB mimics and developing drug resistance. However, OA TB is still perceived as a “diagnostic enigma” in non-endemic regions, leading to a delay in diagnosis. Hence, a high index of suspicion, especially in a high-risk population, is needed to improve the diagnosis. Evolving drug resistance continues to thwart efforts to control the disease globally. This review article discusses the perceptions and practices in different parts of the world, with India as an example of the endemic world, and lays down priorities for overcoming the challenges of diagnosing osteoarticular TB.

A 62-year-old, obese woman, smoking 10 pack/year was admitted to the National Tuberculosis and Lung Diseases Research Institute to diagnose small, round opacities revealed by routine chest X-ray examination. These lesions had been observed for 5 years. The patient had been treated for psoriasis, hypertension, and insulin-independent diabetes. On admission she was in good condition, complaining of a slight productive cough as well as intermittent osteoarticular pain. Physical examination revealed cutaneous psoriatic lesions, slight edema of the lower limbs, and clubbed fingers. Tuberculin test was positive. Chest Computer Tomography scanning showed partially calcified nodules (up to 1cm in diameter) located in the middle and base areas of both lungs. No evidence of hilar nor mediastinal lymph node enlargement was seen. Lung specimens displayed intraalveolar and intravascular growth of neoplastic cells. Immunohistochemical expression of Factor VIII, CD31 and CD34 antigens was present. Pulmonary epithelioid haemangioendothelioma was diagnosed. After 6 months of observation, progression of the disease was shown. Interferon alpha treatment was introduced. During the therapy, a slight regression of pulmonary changes was noticed and since then stabilization of the disease was observed. Full article
