1/562. Pulmonary tuberculosis following successful treatment of pulmonary infection with mycobacterium kansasii.

    A case of pulmonary tuberculosis following successful treatment of pulmonary infection with mycobacterium kansasii is presented. The immunizing effect of an infection with M kansasii and and other nonspecific immune factors are discussed. ( info)

2/562. Infectious crystalline keratopathy and endophthalmitis secondary to Mycobacterium abscessus in a monocular patient with stevens-johnson syndrome.

    PURPOSE: To describe the clinical and laboratory features of infectious crystalline keratopathy and endophthalmitis secondary to Mycobacterium abscessus in a patient with stevens-johnson syndrome. METHOD: Case report. A 19-year-old man with a history of stevens-johnson syndrome and multiple corneal transplants developed white crystalline corneal infiltrates. RESULTS: anterior chamber aspirate disclosed acid-fast bacilli. A repeat corneal transplant was performed and antibiotic therapy begun. Histopathology showed focal acute inflammation surrounding collections of acid-fast bacilli, which were speciated as M. abscessus. CONCLUSIONS: M. abscessus is a cause of infectious crystalline keratopathy and endophthalmitis. risk factors include ocular surface disease, corneal transplantation, and immunosuppressive therapy.

3/562. Lymphocyte transformation test for the evaluation of adverse effects of antituberculous drugs.

    The usefulness of the lymphocyte transformation test (LTT) for the analysis of adverse reactions to antituberculous drugs was evaluated. - The LTT was performed with isoniazid and rifampicin in 15 tuberculosis and 2 MOTT (Mycobacteria other than tuberculosis)-infection patients who suffered drug reactions, in 23 patients without any adverse reactions, in 7 controls previously exposed to antituberculous drugs, and in 14 controls who had never been exposed. 4/15 of the hepatotoxic reactions only showed a positive LTT with rifampicin, 3/15 only with isoniazid, and in 8/15 the LTT was negative. In an anaphylactoid shock reaction the LTT was extremely exaggerated for both rifampicin and isoniazid. In patients without any side effects only one slightly increased LTT due to isoniazid was observed. Two healthy controls with previous contact to these drugs showed a positive LTT for isoniazid, one of those with both rifampicin and isoniazid. The LTT was negative in all control persons without any former contact to antituberculous medications. In most cases hepatotoxicity seems to be a pure toxic reaction without the participation of cellular immune mechanisms. LTT can be useful for identifying the drug responsible for immunological side effects. ( info)

4/562. Central line sepsis in a child due to a previously unidentified mycobacterium.

    A rapidly growing mycobacterium similar to strains in the present mycobacterium fortuitum complex (M. fortuitum, M. peregrinum, and M. fortuitum third biovariant complex [sorbitol positive and sorbitol negative]) was isolated from a surgically placed central venous catheter tip and three cultures of blood from a 2-year-old child diagnosed with metastatic hepatoblastoma. The organism's unique phenotypic profile and ribotype patterns differed from those of the type and reference strains of the M. fortuitum complex and indicate that this organism may represent a new pathogenic taxon.

5/562. Flexor tenosynovitis in the hand caused by Mycobacterium terrae.

    The authors describe an uncommon case of flexor tenosynovitis caused by Mycobacterium terrae, an atypical mycobacterium generally considered nonpathogenic in humans. A prolonged delay in diagnosis and various ineffective therapies led to synovial biopsy and culture. After confirming the diagnosis of M. terrae, appropriate antimycobacterial chemotherapy resolved the synovitis. For chronic tenosynovitis without a clear etiology, limited synovectomy and culture are essential in establishing a diagnosis and in initiating treatment for this atypical mycobacterial infection.

6/562. Acquired resistance to rifampicin by mycobacterium kansasii.

    Two patients with mycobacterium kansasii infection of the lung had organisms sensitive to rifampicin. Following treatment, essentially with rifampicin alone, the patients began to excrete organisms completely resistant to rifampicin. The ability of M. kansasii to acquire resistance to rifampicin during treatment has been clearly demonstrated. This reinforces the need to treat this infection with an adequate multiple drug regimen.

7/562. mycobacterium fortuitum spinal infection: case report.

    Acute paraplegia followed a vertebral infection with mycobacterium fortuitum. There was a satisfactory response to surgery and antibiotics. No predisposing factors for this primary bone infection could be found. ( info)

8/562. mycobacterium fortuitum meningitis associated with an epidural catheter: case report and a review of the literature.

    mycobacterium fortuitum is a rapidly growing organism that has rarely been associated with meningitis. A patient developed M. fortuitum meningitis as the result of a permanent indwelling, contaminated, epidural catheter. diagnosis and treatment of the disease are difficult in that clinical features may be indolent, and many antimicrobials with activity against M. fortuitum have minimal cerebrospinal fluid penetration. This patient was cured with an antibiotic regimen that consisted of doxycycline, ciprofloxacin, imipenem, and clarithromycin, and removal of the epidural catheter. ( info)

9/562. mycobacterium marinum infection from a tropical fish tank. Treatment with trimethoprim and sulphamethoxazole.

    A paronychial granuloma on the left thumb, in a man who kept tanks of tropical fish, was followed by cutaneous nodules on the left upper limb and tender lymph nodes in the left axilla. mycobacterium marinum was isolated from the lesion on the thumb and also from the tank water. Subsidence of the lesions followed administration of trimethoprim and sulphamethoxazole. ( info)

10/562. Mycobacterial central venous catheter tunnel infection: a difficult problem.

    We report our experience of non-tuberculous mycobacterial infection associated with the tunnel of Hickman-Broviac central venous catheters in immunosuppressed patients with haematological malignancies undergoing high-dose chemotherapy supported by BMT. The problem is rare and difficult to treat. Our cases are unique in developing tunnel site mycobacterial infection well after the tunnelled catheters were removed. We diagnosed one case of mycobacterium chelonae, which is a well-documented cause of such infections, and two cases of mycobacterium haemophilum, which are the first reported cases in this setting. Early wide surgical excision of the infected tunnel site and prolonged antibiotic therapy is necessary. Despite these measures recurrence occurred in two cases. Close liaison with the microbiology laboratory is needed to ensure the appropriate culture media and conditions are used for these fastidious organisms. Empiric antibiotic regimens should be based on the likely organism. Drugs active against M. chelonae and M. haemophilum should be included. ( info)
