UNASSIGNED: Tuberculosis (TB) remains a pervasive infectious disease, and extrapulmonary manifestations account for a significant proportion of cases. Skeletal involvement is observed in about 10% of extrapulmonary TB instances. While spinal TB is relatively common, sacroiliac (SI) joint TB is a rare occurrence, particularly in immunocompetent individuals.
UNASSIGNED: This case report discusses an unusual presentation in a 19-year-old immunocompetent lady where the spine, acetabulum, and SI joint were concurrently affected. The patient, initially undergoing alternative medicine, exhibited severe pain, weight loss, and restricted mobility. Radiological evaluations, including X-rays and magnetic resonance imaging, revealed extensive vertebral and pelvic destruction with abscess formation. Surgical debridement and stabilization, alongside antitubercular treatment, led to significant improvement.
UNASSIGNED: This case emphasizes the challenges in diagnosing multifocal skeletal TB, highlights the importance of early intervention, and underscores the impact of alternative medicine on treatment delays. A multidisciplinary approach involving histopathological and microbiological examinations is crucial for optimal management.

Tuberculous pericarditis (TBP) is an important cause of pericarditis worldwide while being infrequent in childhood, especially in low-TB-incidence countries. We report a case of TBP and provide a systematic review of the literature, conducted by searching PubMed, Scopus, and Cochrane to find cases of TBP in pediatric age published in the English language between the year 1990 and the time of the search. Of the 587 search results obtained, after screening and a backward citation search, 45 studies were selected to be included in this review, accounting for a total of 125 patients. The main signs and symptoms were fever, cough, weight loss, hepatomegaly, dyspnea, and increased jugular venous pressure or jugular vein turgor. A definitive diagnosis of TBP was made in 36 patients, either thanks to microbiological investigations, histological analysis, or both. First-line antitubercular treatment (ATT) was administered in nearly all cases, and 69 children underwent surgical procedures. Only six patients died, and only two died of TBP. TBP in childhood is relatively uncommon, even in high-TB-prevalence countries. Clinical manifestations, often suggestive of right-sided cardiac failure, are subtle, and diagnosis is challenging. TBP has an excellent prognosis in childhood; however, in a significant proportion of cases, invasive surgical procedures are necessary.

Acute paraplegia in pregnancy is uncommon but can result from pathology including Guillain-Barre syndrome, acute transverse myelitis, and spinal tuberculosis, also known as Pott\'s disease of the spine. India has a high incidence of tuberculosis (2.8 million cases annually) therefore spinal tuberculosis is a particularly important disease to consider during pregnancy. Management of spinal tuberculosis in pregnancy poses a challenge especially at term gestation as immobilization of the spine and maintaining supination is difficult, particularly at delivery.

OBJECTIVE: The hepatoprotective properties of scopoletin have been explored in carbon tetrachloride (CCl4) induced liver injury but not in drug-induced liver injury (DILI) scenarios. Only N-acetyl-cysteine (NAC) has proven efficacy in DILI treatment. Accordingly, we conducted a study to assess the hepatoprotective action of scopoletin in the anti-tubercular treatment (ATT)-DILI model in Wistar rats, if any.
METHODS: A total of 36 rats were evaluated, with six in each group. A 36-day ATT at 100 mg/kg dose for isoniazid, 300 mg/kg for rifampicin and 700 mg/kg for pyrazinamide were fed to induce hepatotoxicity in rats. Group I and II-VI received normal saline and ATT, respectively. Oral scopoletin (1,5 and 10 mg/kg) and NAC 150 mg/kg were administered in groups III, IV, V and VI, respectively, once daily for the last 15 days of the experiment. LFT monitoring was performed at baseline, days 21, 28, and 36. Rats were sacrificed for the histopathology examination.
RESULTS: Aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP) and bilirubin levels were significantly increased in group II (receiving ATT) compared to normal control on day 28 and day 36 (p<0.05). All three doses of scopoletin and NAC groups led to the resolution of AST, ALT, ALP, and bilirubin changes induced by ATT medications effect beginning by day 28 and persisting on day 36 (p<0.01). An insignificant effect was observed on albumin and total protein levels. The effect was confirmed with antioxidants and histopathology analysis.
CONCLUSIONS: The study confirms the hepatoprotective efficacy of scopoletin in a more robust commonly encountered liver injury etiology.

Tuberculosis (TB) is currently the second deadliest infectious disease. Existing antitubercular therapies are long, complex, and have severe side effects that result in low patient compliance. In this context, nanosized drug delivery systems (DDSs) have the potential to optimize the treatment\'s efficiency while reducing its toxicity. Hundreds of publications illustrate the growing interest in this field. In this review, the main challenges related to the use of drug nanocarriers to fight TB are overviewed. Relevant publications regarding DDSs for the treatment of TB are classified according to the encapsulated drugs, from first-line to second-line drugs. The physicochemical and biological properties of the investigated formulations are listed. DDSs could simultaneously (i) optimize the therapy\'s antibacterial effects; (ii) reduce the doses; (iii) reduce the posology; (iv) diminish the toxicity; and as a global result, (v) mitigate the emergence of resistant strains. Moreover, we highlight that host-directed therapy using nanoparticles (NPs) is a recent promising trend. Although the research on nanosized DDSs for TB treatment is expanding, clinical applications have yet to be developed. Most studies are only dedicated to the development of new formulations, without the in vivo proof of concept. In the near future, it is expected that NPs prepared by \"green\" scalable methods, with intrinsic antibacterial properties and capable of co-encapsulating synergistic drugs, may find applications to fight TB.

UNASSIGNED: Extrapulmonary tuberculosis (TB) mainly involves the spine and weight-bearing joints and sternal TB accounts for only 1% of musculoskeletal TB cases. Diagnosis and management of sternal TB propose a challenge at times due to the rarity and unfamiliarity of the presentations.
UNASSIGNED: We present two cases of TB of sternum that presented to our institute. The first patient was a 52-year-old male with 2 months history of swelling over the chest wall and the second was a 19-year-old female who presented with swelling for 1 week. Both patients were managed with anti-tubercular drugs for 12 months and had complete resolution of the disease. The patients were not on any medication prior to their presentations.
UNASSIGNED: Isolated sternal TB is an exceedingly rare form of TB which usually presents as a chest wall swelling without any constitutional symptoms. Antitubercular medication is the mainstay of treatment and surgical intervention is reserved for only few cases.

Despite the availability of effective treatment regimens for cutaneous tuberculosis, challenges to disease control result from delayed diagnosis, infection with multidrug-resistant mycobacterial strains, and coinfection with HIV. Delayed diagnosis can be mitigated when dermatologists are sensitized to the clinical signs and symptoms of infection and by the incorporation of appropriate diagnostic tests. All cases of cutaneous tuberculosis should be confirmed with histopathology and culture with or without molecular testing. In each case, a thorough evaluation for systemic involvement is necessary. Mycobacteria may not be isolated from cutaneous tuberculosis lesions and therefore, a trial of antituberculosis treatment may be required to confirm the diagnosis. The second article in this 2-part continuing medical education series describes the sequelae, histopathology, and treatment of tuberculosis.

UNASSIGNED: To assess the performance of interferon-gamma release assay (IGRA) associated with tuberculosis skin test (TST) for ocular tuberculosis (OTB) diagnosis and therapeutic decision making.
UNASSIGNED: One hundred and ninety-one patients with ocular inflammation were prospectively followed-up. Patients with clinical signs highly suspected of OTB, TST≥10 mm, and/or IGRA≥0.35 IU/mL received antitubercular therapy (ATT). Sensitivity (Se), specificity (Sp), and area under the curve (AUC) were assessed.
UNASSIGNED: Seventy-two (37.7%) patients received ATT for presumed OTB. Combining TST and IGRA had Se=89.6%, Sp=99.2%, and AUC (0.98) significantly higher compared to TST (0.85, Z=6.3, p<.001) or IGRA (0.95, Z=2.5, p=.01). Prior history of corticosteroids or immunosuppressant with concomitantly oral prednisone and baseline IGRA> 2.0 IU/mL was associated significantly with more recurrences in ATT patients (p=.01)      .
UNASSIGNED: Considering TST and IGRA together was more effective in assessing OTB diagnosis. The real value of the IGRA test to predict recurrences needs further studies.

BACKGROUND: Spinal intramedullary tuberculoma (IMT) is a rare manifestation of extrapulmonary tuberculosis (TB). Presentation of TB in the pediatric age group is a significant contributor to mortality.
METHODS: A young vaccinated girl presented to the neurosurgery department with difficulty walking and urinary incontinence. A magnetic resonance imaging performed outside the hospital showed a hyperintense intramedullary lesion extending from T6 to T9. The patient underwent T6-T9 laminoplasty with intramedullary lesion decompression under neuromonitoring. The dense adherence of the lesion to the cord and nerve roots permitted only debulking. Histopathological examination confirmed the diagnosis of tuberculoma. The patient was started on antitubercular treatment and was then subsequently discharged. After 8 months, the patient was reviewed and showed improvement in her symptoms and complete resolution of the lesion on imaging. The patient has now developed hydrocephalus on the latest computed tomography imaging, which may be due to tubercular meningitis or arachnoiditis.
CONCLUSIONS: Complete resolution of spinal IMT is possible with a combined treatment approach.

Ocular tuberculosis (OTB) is a rare, extrapulmonary manifestation of systemic TB, which has been a global etiology of uveitis for centuries, though concentrated in the developing world. OTB remains difficult to diagnose clinically despite a plethora of conventional and modern investigations. Tubercular retinal vasculitis (TRV) is a common and specific presentation of OTB but is variably defined in the literature in terms of clinical profile and the investigations essential for diagnosis and treatment. Ironically, the need and duration of antitubercular treatment is uncertain for this manifestation of ocular TB. The rationale and utility for corticosteroids is similarly equivocal for TRV. This review attempts to tease out a commonsense approach from the best available evidence and consensus in the literature to suspect, investigate and diagnose TRV with reasonable certainty, and institute appropriate treatment with due ethnic and geographic considerations.
