Susac's syndrome or catastrophic antiphospholipid syndrome?

Susac's syndrome is a microangiopathic disorder of unknown pathogenesis presenting with encephalopathy, hearing loss and branch retinal artery occlusions. The term 'catastrophic' antiphospholipid syndrome (APS) is used to define a subset of the APS characterized by thrombotic microangiopathy with clinical evidence of three or more organ involvement developed in a short period of time. We describe a patient with typical features of Susac's syndrome, that appeared in less than a week, in whom aPL were detected, thus fulfilling criteria for 'probable' catastrophic APS.

Disseminated candidiasis in addicts who use brown heroin: report of 83 cases and review.

From November 1983 to April 1990, disseminated candidiasis was diagnosed in 83 heroin addicts at our institution. All patients had consumed brown heroin diluted in fresh lemon juice. Sixty-two (75%) had skin lesions, 41 (49%) had ocular lesions, and 35 (42%) had one or several costochondral tumors. Candida albicans was grown in culture or histopathologically identified in 34 cases (41%). The patients who had only cutaneous lesions were treated with ketoconazole, and they were all cured. The patients with ocular involvement received systemic amphotericin B with or without oral flucytosine; 29 of these patients developed varying degrees of vision loss. The method of treatment of costochondral tumors was not uniform; in 14 cases the lesions were resected. The one patient who died developed endocarditis involving the aortic valve. Cases of pleuropulmonary involvement, spondylitis, and large-joint arthritis have also been described among the 300 cases reported in the reviewed literature. This is a new syndrome of candidal infection in drug addicts who use brown heroin; ocular lesions are the most harmful manifestation, and loss of vision is the major sequela.

Risk factors for nosocomial bacteremia in a large Spanish teaching hospital: a case-control study.

OBJECTIVE: Identify independent risk factors associated with the development of nosocomial bacteremia. DESIGN: Exploratory, unmatched, case-control study. SETTING: A 970-bed Spanish university hospital. PATIENTS: All non-neutropenic adult patients with nosocomial bacteremia admitted during a 12-month period were eligible as cases. All adult non-neutropenic patients without nosocomial bacteremia were eligible as controls. RESULTS: The incidence of bacteremia in the study population was 6.9/1000 admissions/year. One hundred eighty cases and 180 controls were analyzed. Multivariate analysis (stepwise logistic regression techniques) identified seven risk factors independently associated with nosocomial bacteremia: age above 65 years; prior admission (within six months) to the hospital; underlying diseases that were ultimately or rapidly fatal; indwelling urethral catheter in place for more than three days; intravenous central lines or peripheral venous lines (if in place for more than four days); "high-risk surgery" (i.e., lower abdominal, cardiac or thoracic); and admission to an intensive care unit. CONCLUSIONS: Although five variables are not modifiable, the remaining two relate to the use and duration of devices. Our data give strong support for the value of testing strict guidelines for limiting vascular catheters and evaluating the need for prolonged urethral catheterization. If effective infection control measures are identified, we could target hospital-wide surveillance to patients whose risk factors are amenable to intervention.

Characteristics of tuberculosis in HIV-infected patients: a case-control study.

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.

Ophthalmic manifestations of acquired immunodeficiency syndrome. A study of thirty-four patients.

Ophthalmic manifestations were studied in 34 patients suffering from AIDS. Ophthalmic disorders were found in 20 of these (58%), the most frequent being a cotton-wool-type spot (94.7%). Three patients showed an ophthalmic state compatible with choroid ischemia and atrophy of the pigmented epithelium of the retina. Three patients had necrotizing retinitis probably of viral etiology (cytomegalovirus). Other disorders observed were intraretinal hemorrhages, Roth's spots, microaneurysms, periphlebitis and ocular infiltration by Kaposi's sarcoma.
