ABSTRACT
Worldwide, around 10 million people fall sick every year because of Tuberculosis (TB). In India, the incidence is 2.69 million cases. Central nervous system Tuberculosis (CNS TB), which is one of the most deadly forms of tuberculosis (TB) mainly manifests as TB Meningitis followed by Tuberculoma, Tubercular abscess and other forms. CNS TB is seen in 5 to 10% of extra-pulmonary TB cases, and accounts for 1% of all TB cases and has the highest mortality. They usually present with symptoms such as headache and seizures. They may have other signs and symptoms based on the size and the location of the lesions. The advent of modern technology such as CT, MRI scans helped to diagnose early. Diagnosis is established by CT/MRI Brain, where a granulomatous lesion with/without perilesional edema is seen. MR Spectroscopy brain is indicated when the diagnosis is doubtful. Presence of lipid peak on MR Spectroscopy is diagnostic of CNS Tuberculomas. Medical management is adequate and there is no role for surgery. A course of ATT for 6 months along with corticosteroids is adequate. Addition of corticosteroids is necessary to reduce the paradoxical response; it also reduces the size of the lesion and perilesional edema. Anti epileptic drugs are not necessary. CNS Tuberculoma is curable if treated properly.
ABSTRACT
Hepatitis associated anti-tuberculous treatment (HATT) has been a main obstacle in managing patients co-infected with Mycobacterium tuberculosis and hepatitis B virus (HBV).Therefore,we evaluated the factors related to the severity of adverse effects during HATT,especially those associated with liver failure.A retrospective study was carried out at Tongji Hospital from 2007 to 2012.Increases in serum transaminase levels of＞3,5,and 10 times the upper limit of normal (ULN) were used to define liver damage as mild,moderate,and severe,respectively.Patients with elevated total bilirubin (TBil) levels that were more than 10 times the ULN (＞171 μrnol/L) with or without decreased (＜40％) prothrombin activity (PTA) were diagnosed with liver failure.A cohort of 87 patients was analyzed.The incidence of liver damage and liver failure was 59.8％ (n=52) and 25.3％ (n=22),respectively.The following variables were correlated with the severity of hepatotoxicity:albumin (ALB) levels,PTA,platelet counts (PLT),and the use of antiretroviral therapies (P＜0.05).Hypo-proteinemia and antiretroviral therapy were significantly associated with liver failure,and high viral loads were a significant risk factor with an odds ratio (OR) of 2.066.Judicious follow-up of clinical conditions,liver function tests,and coagulation function,especially in patients with high HBV loads and hypoalbuminemia is recommended.It may be advisable to reconsider the use of antiviral drugs failure during the course of anti-tuberculous treatment of HBV infection patients to avoid the occurrence of furious liver failure.
ABSTRACT
Tuberculous infection of the upper respiratory tract is an uncommon clinical condition and in that nasopharyngeal involvement is struck with rarity per se. This condition is often prevalent in people of low socioeconomic strata living in endemic areas, especially in developing countries. It has a silent and indolent course and most commonly mimicks nasopharyngeal carcinoma in its clinical presentation. In absence of concurrent pulmonary involvement, it is often misdiagnosed or diagnosed only after the biopsy has been taken. Nevertheless, high index of suspicion is required on part of the clinician to diagnose this comparatively rare entity.
