Additionally, a study by Maurya et al. conducted in 2013 shows evidence that there is a burden of multidrug-resistant tuberculosis in India and change is needed for testing, surveillance, monitoring and management. During the COVID-19 pandemic, 80% fewer TB cases were reported daily in April 2020 in India, reducing the diagnosis and treatment of TB. Trial of therapy
In areas where TB is highly endemic, it is not unusual to encounter patient with a fever, but in whom no source of infection is found. The physician may then, after extensive investigation has excluded all other diseases, resort to a trial of TB treatment. The regimen used is HEZ for a minimum of three weeks; RMP and STM are omitted from the regimen because they are broad spectrum antibiotics, whereas the other three first-line drugs treat only mycobacterial infection. Resolution of the fever after three weeks of treatment is good evidence for occult TB and the patient should then be changed to conventional TB treatment (2HREZ/4HR). If the fever does not resolve after three weeks of treatment then it is reasonable to conclude that the patient has another cause for his fever. This approach is not recommended by the WHO and most national guidelines. Surgical treatment
Surgery has played an important part in the management of tuberculosis since the 1930s. Historical surgical management
The first successful treatments for tuberculosis were all surgical. They were based on the observation that healed tuberculous cavities were all closed. Surgical management was therefore directed at closing open cavities to encourage healing.
There is no proven benefit to adjuvant chemotherapy or supplementing other treatments for this kind of tumor. Although temozolomide is effective for treating recurrent anaplastic astrocytoma, its role as an adjuvant to radiation therapy has not been fully tested.Quality of life after treatment depends heavily on the area of the brain that housed the tumor. In many cases, patients with anaplastic astrocytoma may experience various types of paralysis, speech impediments, difficulties planning and skewed sensory perception. Most cases of paralysis and speech difficulties can be rehabilitated with speech, occupational, physical, and vision therapy. Prognosis
The age-standardized 5-year relative survival rate is 23.6%. Patients with this tumor are 46 times more likely to die than matched members of the general population. It is important to note that prognosis across age groups is different especially during the first three years post-diagnosis. When the elderly population is compared with young adults, the excess hazard ratio (a hazard ratio that is corrected for differences in mortality across age groups) decreases from 10.15 to 1.85 at 1 to 3 years, meaning that the elderly population are much more likely to die in the first year post-diagnosis when compared to young adults (aged 15 to 40), but after three years, this difference is reduced markedly. Typical median survival for anaplastic astrocytoma is 2–3 years. Secondary progression to glioblastoma multiforme is common. Radiation, younger age, female sex, treatment after 2000, and surgery were associated with improved survival in AA patients. == References ==
