1/38. mycobacterium tuberculosis infection in allogeneic bone marrow transplantation patients.Bone marrow transplant (BMT) recipients are prone to bacterial, viral and fungal infections. mycobacterium tuberculosis infection can occur in these patients, but the incidence is lower than that of other infections. This report describes four patients with mycobacterium tuberculosis infection identified from 641 adult patients who received a BMT over a 12-year period (prevalence 0.6%). The pre-transplant diagnosis was AML in two patients and CML in the other two. Pre-transplant conditioning consisted of BU/CY in three patients and CY/TBI in one. Graft-versus-host disease (GVHD) prophylaxis was MTX/CsA in three patients and T cell depletion of the graft in one patient. Sites of infection were lung (two), spine (one) and central nervous system (one). Onset of infection ranged from 120 days to 20 months post BMT. Two patients had co-existing CMV infection. One patient had graft failure. The two patients who received anti-tuberculous (TB) therapy recovered from the infection. Although the incidence of tuberculosis in BMT patients is not as high as in patients with solid organ transplants, late diagnosis due to the slow growth of the bacterium can lead to delay in instituting anti-TB therapy. A high index of suspicion should be maintained, particularly in endemic areas.- - - - - - - - - - ranking = 1keywords = central nervous system, nervous system (Clic here for more details about this article) |
2/38. Acute isoniazid neurotoxicity during preventive therapy.OBJECTIVE: To describe rare side effects of treatment with isoniazid. DESIGN: Descriptive case report. SETTING: Medical intensive care unit in a university medical center. PATIENT: A 14-yr old previously healthy girl receiving preventive isoniazid therapy who suddenly developed generalized tonic-clonic seizures and coma. INTERVENTIONS: Patient was sedated and mechanically ventilated. She also received pyridoxine intravenously. MEASUREMENTS AND MAIN RESULTS: An isoniazid overdose was not confirmed. Computed tomography of the brain and electroencephalogram revealed nothing abnormal. seizures gradually disappeared within 2 hrs after sedation and treatment with pyridoxine. The patient was discharged on day 14 without consequences and has been well for 10 mos. No seizures reappeared after isoniazid was discontinued. CONCLUSIONS: We caution against possible isoniazid neurotoxicity in healthy individuals using recommended preventive doses.- - - - - - - - - - ranking = 0.20558970414593keywords = brain (Clic here for more details about this article) |
3/38. Serious complications of tuberculous epididymitis.Tuberculous epididymitis is a rare entity associated with minor complications. We present two cases of tuberculous epididymitis associated with serious complications (bilateral psoas abscesses and Addison's disease with psoas abscess). A review of the literature disclosed six additional cases associated with serious complications (Addison's disease, inappropriate antidiuretic hormone secretion, central nervous system involvement) which are discussed and compared to these cases. We conclude that tuberculous epididymitis represents a grave sequela of genital tract involvement and may be associated with serious and even fatal complications.- - - - - - - - - - ranking = 1keywords = central nervous system, nervous system (Clic here for more details about this article) |
4/38. Paradoxical enlargement of tuberculous brain abscess during drug treatment: a case report.This is a case report of a patient suffering from tuberculous (TB) brain abscesses. Despite supervised and appropriate anti-TB chemotherapy, the size of the abscesses paradoxically increased, accompanied by clinical deterioration at 1 month. A second aspiration was performed which yielded a large amount of viable tubercle bacilli. The same drug regimen was continued. This was followed by complete resolution of the lesions in 12 months. Hence TB brain abscess which remains culture and smear positive after four weeks treatment may not represent treatment failure.- - - - - - - - - - ranking = 1.2335382248756keywords = brain (Clic here for more details about this article) |
5/38. chlamydia trachomatis and mycobacterium tuberculosis lung infection in an hiv-positive homosexual man.A 31-year-old homosexual man, who was human immunodeficiency virus (hiv)-positive was admitted for fever and cough. Chest computed tomography (CT) revealed the presence of diffuse interstitial reticular nodulation, and brain nuclear magnetic resonance imaging showed the presence of nodular frontal lesions. Microscopic examination of sputum and other body fluids showed the presence of acid-fast bacilli and culture-only growth mycobacterium tuberculosis. serology for respiratory tract pathogens was negative except for Chlamydia. An antibody titer in the immunoglobulin g (IgG) class of 1:64 for Chlamydia pneumoniae and, unexpectedly, an antibody titer of 1:1024 for C. trachomatis were found. The patient was successfully treated with antituberculosis agents, and clarithromycin, for presumptive chlamydial infection.- - - - - - - - - - ranking = 0.20558970414593keywords = brain (Clic here for more details about this article) |
6/38. Multiple tuberculous brain abscesses.Multiple tuberculous brain abscesses are rare. This report presents a female patient with a rapidly deteriorating clinical course. Computed tomographic scanning revealed multiple brain abscesses. Aspiration of one of the lesions yielded pus and positive acid-fast stained bacilli. The pathogenesis of multiple tuberculous brain abscesses is discussed.- - - - - - - - - - ranking = 1.4391279290215keywords = brain (Clic here for more details about this article) |
7/38. Eales' disease with neurological involvement. Part 2. pathology and pathogenesis.Detailed neuropathologic examination was carried out on 1 case of Eales' disease with CNS involvement, in the form of retinal vasculopathy, followed first by signs of brain stem and cerebellar disease and then by a myelopathy, with death 4 years later from retinal infection. There was mild chronic inflammation in the retina, and sub-total demyelination of one optic nerve. The brain stem and cerebellum showed extensive vasculopathy, with various stages of venous change extending from proliferation and dilatation to haemorrhage, or to thickening with hyalinisation. The perivenular brain tissue, particularly of the cerebellum, often showed demyelination, with relative axon preservation, but no inflammation. Similar, but less pronounced venopathy was seen in the dorsal cord. There was ascending degeneration of Goll's columns and descending degeneration of the lateral columns.- - - - - - - - - - ranking = 0.61676911243778keywords = brain (Clic here for more details about this article) |
8/38. Failure of therapy for tuberculosis in human immunodeficiency virus infection.Optimum treatment of tuberculosis in persons with human immunodeficiency virus (hiv) infection is still being defined. Tuberculosis treatment failure in an hiv-infected patient is described and 10 similar cases from the medical literature are reviewed to search for common patterns associated with an adverse outcome of therapy in this setting. Six patients were poorly compliant. In nine patients, the subsequent episode of tuberculosis was disseminated or extrapulmonary; in four the central nervous system was involved. In five patients, a problem with rifampin usage was encountered: Three had rifampin-resistant mycobacterium tuberculosis, one experienced an adverse reaction to rifampin, leading to withdrawal from the regimen after 1 week, and one was receiving a drug that may interfere with rifampin's antimycobacterial effect. This case report and literature review suggest that particular attention should be directed toward ensuring that patients with hiv infection comply with treatment of tuberculosis. For the majority of patients, the already stretched resources available for the treatment of tuberculosis and hiv infection should be devoted to compliance enhancement rather than to more prolonged or intensive drug regimens. However, it should be emphasized that patients with disseminated tuberculosis or central nervous system disease and those who are not able to receive rifampin because of drug resistance or an adverse reaction should be managed individually.- - - - - - - - - - ranking = 2keywords = central nervous system, nervous system (Clic here for more details about this article) |
9/38. Intra-cranial lesions in a patient with Hodgkin lymphoma.central nervous system (CNS) lesions in newly diagnosed, advanced Hodgkin's disease (HD) commonly suggest intracranial involvement with HD. However, occasionally this could be the result of a CNS infection. We report a case of concurrent CNS tuberculosis in a patient with stage III E HD the first reported in the English literature. Management of this case and the literature pertaining to infectious complications of HD are reviewed.- - - - - - - - - - ranking = 0.24426504407618keywords = nervous system (Clic here for more details about this article) |
10/38. Disseminated mycobacterium avium infection in a 20-year-old female with partial recessive IFNgammaR1 deficiency.We report the case of a 20-year-old female with disseminated mycobacterium avium disease involving bones, lungs and brain. She was completely healthy up until the present illness and had been vaccinated with BCG in infancy without complications. Mycobacteriosis progressed in spite of treatment with antituberculous drugs and was controlled only after addition of interferon-gamma subcutaneously. A homozygous hypomorphic I87T mutation was found in the gene encoding the ligand-binding chain of the IFN-gamma receptor (IFNgammaR1). This mutation is the only known recessive hypomorphic lesion in IFNGR1 and had been reported before in only 1 child with curable BCG infection and his sibling with primary tuberculosis. Our report illustrates the clinical heterogeneity of patients sharing exactly the same form of partial recessive IFNgammaR1 deficiency. A diagnosis of partial recessive IFNgammaR1 deficiency should be contemplated in adults with unexplained environmental mycobacterial diseases.- - - - - - - - - - ranking = 0.20558970414593keywords = brain (Clic here for more details about this article) |
