Heater-cooler units manufactured by LivaNova prior to September 2014 and used during cardiopulmonary bypass have been linked to M. chimera, which causes a latent infection that may be activated and become disseminated in cases of immunosuppression related to steroid use.
Compound 2b can be considered as a new drug candidate to continue its development against M. tuberculosis MDR strains.
To determine the frequency and antimicrobial susceptibility pattern of extra-pulmonary tuberculosis in Rawalpindi.
To test the hypothesis that HIV infection can modify the clinical characteristics of tuberculosis, 65 consecutive cases of tuberculosis in HIV-seropositive patients diagnosed in Barcelona (Spain) were compared with 65 HIV-seronegative controls matched for age and sex. Thirty of the 65 cases were accepted as AIDS cases (August 1987 Centers for Disease Control criteria) only because of the tuberculosis. Among the cases 54 (83%) were parenteral drug addicts and 88% were males. The tuberculosis was pulmonary or pleural in 62 controls (96%) but in only 25 cases (39%; P less than 0.0001). Lymph nodes were involved in 25 cases (39%) and in none of the controls (P less than 0.0001). Disseminated forms of tuberculosis were present in seven cases (11%) and in no controls (P less than 0.007). Bone, joints and central nervous system involvement were also significantly (P less than 0.05) more frequent in cases. The treatment (isoniazid and rifampin for 6 months plus ethambutol and pyrazinamide during the first 2 months) was always effective. One relapse was detected after a median follow-up of 55 months in cases and none in controls after a median follow-up of 43 months. Twenty-five cases (39%) and 14 controls (22%) developed mild or severe side effects related to the treatment (P less than 0.004). In conclusion, most of the HIV-infected patients with tuberculosis were drug addicts with extrapulmonary or disseminated forms. A short course of treatment (6 or 9 months) may be enough but side effects were frequent.

We describe the case of a 36-years-old male patient, originating from India, who presented with enlarged cervical lymph nodes and elevated liver chemistry tests. Histologically necrosing granulomas were observed in the lymph nodes, and PCR revealed DNA from mycobacterium tuberculosis. However, in the liver biopsy granulomatous hepatitis without central necrosis was seen. With a positive PCR for mycobacteria from liver tissue and no evidence for other hepatic diseases we started drug treatment with standard quadruple regimen consisting of isoniazid, rifampicin, ethambutol, and pyrazinamide. Five days after onset of therapy, liver chemistry tests rose 10-fold, forcing us to interrupt treatment. Gradual step-wise re-exposition with the same medication after return of liver chemistry tests to baseline was well tolerated without any further side effects. Liver involvement of tuberculosis can have many facets and may be treated by gradual dosing of standard drugs.

Four cases of chronic granulomatous skin infections (two due to Sporothrix schenckii and two to Mycobacterium marinum) were treated primarily by the intermittent application of local hyperthermia. This treatment was initiated either because of intolerance to conventional iodide therapy for sporotrichosis or as interim therapy while awaiting diagnosis of the mycobacterial infections. The response indicated that the application of heat is a useful adjunct to the therapy of these infections. Our experience, and that of others, suggests that in some cases heat alone may be curative.
