Fibroblastic rheumatism.

We report the first known South African case of fibroblastic rheumatism, a rare dermatoarthropathy. Our patient presented with the typical clinical features of a sudden-onset, erosive polyarthritis with cutaneous nodules and sclerodactyly. Significant functional loss occurred within a period of 3 to 4 months. X-rays of the hands showed a single erosion, whereas magnetic resonance imaging showed further erosions as well as soft tissue and synovial enhancement. The unique histologic findings of fibroblastic proliferation, thickened collagen, and dermal fibrosis confirmed the diagnosis of fibroblastic rheumatism. Our patient was treated with a combination of methotrexate and oral prednisolone with subsequent resolution of her synovitis/arthritis and no further progression of her sclerodactyly and associated functional loss. The course of fibroblastic rheumatism is known to vary and although multiple therapeutic options have been tried, the question remains whether any of the therapies alters the natural course of the disease. However, considering the probable role of lymphocytes and fibrogenic cytokines, an increased awareness with early diagnosis and treatment in the initial inflammatory stage may prevent the development of incapacitating joint sequelae.

Survival of patients with SLE admitted to an intensive care unit-a retrospective study.

We examined the demography, reasons for admission and cause of death in systemic lupus erythematosus (SLE) patients admitted to a medical intensive care unit (ICU) over a 7-year period. Fourteen patients were admitted during this period-all were female, 13 were of mixed ethnic ancestry and one a black South African. Of the 14 patients, 12 were admitted as a result of lupus activity, 2 had sepsis as the major cause of admission, although 5 other patients developed infection during their admission. Five patients had a generalised flare of their disease or progressive renal failure. Seven patients were admitted with a variety of lupus-related pathologies. In general the precise cause of death was difficult to determine. Of the 14 patients, 9 had impaired renal function on admission including 1 with sepsis and 1 of the survivors. Three patients (21%) survived, one with respiratory failure due to shrinking lung, a second with an acute flare of SLE and a third with pulmonary emboli. This study demonstrates that lupus in our community may produce life-threatening flares. Although cause of death was not always definitely identified, admission to the ICU was primarily due to active SLE and not sepsis or iatrogenic disease.

Headaches in patients with systemic lupus erythematosus: a comparative study.

The incidence and nature of headaches in 85 systemic lupus erythematosus (SLE) patients attending an outpatient clinic were studied and compared to those experienced by 61 nurses. The two groups were similar in age, sex and ethnicity. Test-retest assessment of reliability gave both groups 95% confidence limits of 0.09-0.21. Thirty-two (38%) patients developed migrainous headaches and nine (10%) stress headaches with the onset of lupus. In the control group, four (6%) developed migraine and 40 (66%) developed stress headaches on commencing work. We could not document any association of headaches with flares of systemic disease, the ACA syndrome, Raynaud's phenomenon or increased SLEDAI score. We conclude that migrainous headaches are more common in lupus patients than healthy controls, but in an outpatient setting are not statistically associated with flares of systemic disease.

The association between the antiphospholipid antibody syndrome and neuropsychological impairment in SLE.

OBJECTIVE: To examine the relationship between neuropsychological impairment and antiphospholipid antibody syndrome (aPL syndrome) in patients with systemic lupus erythermatosus (SLE). PATIENTS: Sixty-nine patients satisfying ACR criteria were studied. Sixteen patients with the aPL syndrome and 53 patients without the syndrome were subjected to eight neuropsychological tests, a physical examination and serological investigations. No patients with other pathology, known to cause acute or chronic impairment of neuropsychological function, were included. Sixty-five underwent MRI scans. RESULTS: There were no significant differences in age, level of education, incidence of hypertension or disease activity in the two groups. Pearson's correlation coefficients revealed a significant negative correlation with duration of disease in six out of eight tests in the aPL positive group and one out of eight in the aPL negative group. This suggests that aPL syndrome may be involved in the psychological impairment in SLE patients. A larger cohort needs to be studied to confirm this observation.

Community-acquired Staphylococcus aureus bacteraemia in patients who do not abuse intravenous drugs.

Despite advances in antimicrobial therapy and intensive care support, Staphylococcus aureus continues to cause significant morbidity and mortality. We studied community-acquired S. aureus bacteraemia in a population where intravenous drug abuse is extremely uncommon, prospectively reviewing all such patients (n = 113) admitted to Groote Schuur Hospital from February 1986 to January 1991. Overall mortality was 35%. Factors associated with poor outcome were: confusion on presentation, failure to mount a febrile response, acute renal failure, adult respiratory distress syndrome, shock, endocarditis, disseminated intravascular coagulation and platelet count of < 100 x 10(9)/l. Only confusion, acute renal failure and shock were independently associated with death by stepwise regression analysis. Skin infections were the most commonly identified source of bacteraemia (22%), but in 58% of patients the source was not determined. Twenty-six percent of patients were diabetic. Almost all patients (90%) developed one or more complications. In those who survived, therapy was generally prolonged, with a median of 70 days and range of 7-393 days, depending on the associated complications. Community-acquired S. aureus bacteraemia is a serious condition associated with a high complication rate and mortality.

Post-discharge follow-up of stroke patients at Groote Schuur Hospital--a prospective study.

A survey of 59 stroke patients was undertaken between 3 and 6 months after the event to determine whether a weekly stroke round would improve the rate of referral for rehabilitation. Comparison with a previous survey at Groote Schuur Hospital showed a marked improvement (40% for physiotherapy and 10% for occupational therapy v. 76% and 50% respectively). A comparison of referral rates between younger (< 65 years old) and older patients (> 65 years old) revealed a significantly higher rate of referral among the younger patients. Attendance for both groups was low (approx. 7 sessions per 3 months). Social work was an important requirement and 60% of all patients expressed a need for more help. Social needs of older and younger patients differ. Despite the improved referral rate the rehabilitation of stroke patients is unsatisfactory, mainly because of transport difficulties. Methods should be investigated to establish rehabilitation centres in the community to overcome this impasse.

Community-acquired bacteremia in the elderly: a prospective study of 121 cases.

OBJECTIVE: To describe community-acquired bacteremia in the elderly and correlate clinical and laboratory findings with outcome. DESIGN: Prospective study of consecutive cases. SETTING: Large community-based teaching hospital. PATIENTS: One hundred and twenty-one elderly patients aged 65 to 89 years, seen between February 1, 1986 and January 31, 1988. MAIN OUTCOME MEASURES: Bacteriological cultures, symptoms and signs, laboratory findings, and mortality. RESULTS: Gram-negative organisms accounted for 65 (54%) cases and Gram-positive organisms for 47 (39%) cases, while nine (7%) cases were polymicrobial. E. coli (39%), Klebsiella sp. (8%), S. pneumoniae (14%), and S. aureus (12%) were the most commonly isolated organisms. The overall mortality was 38%. A poor prognosis was associated with confusion as a presenting symptom (P < 0.0003), hypotension (P < 0.0003), and inappropriate or delayed treatment (P < 0.02). A good prognosis was associated with E. coli as the pathogen (P < 0.0003) and prompt, appropriate antibiotic therapy. CONCLUSION: Community-acquired bacteremia in the elderly has a high mortality rate. Early recognition and prompt, appropriate treatment are critical in reducing the mortality.

Acute rheumatic fever in adults.

Thirty-one adults with acute rheumatic fever were identified at Groote Schuur Hospital over a 10-year period. In keeping with other series, arthritis was the most common major criterion. However, unlike other series, cardiac involvement was a prominent feature. Two patients died and a further 4 required valve replacements as a result of the disease. This suggests that local factors are of importance in determining the morbidity of the disease and that physicians should consider acute rheumatic disease in adults who present with unexplained valvular disease or carditis.

Socio-economic status and use of contraceptives among unmarried primigravidas in Cape Town.

Unmarried primigravidas were interviewed with regard to their socio-economic status and knowledge and use of contraceptives. The majority were teenagers and were socio-economically ill-equipped to raise a child, although families were generally supportive. They were ignorant of the relationship between sexual intercourse, pregnancy and contraception. Family-planning advice was generally not available to these women. Methods for improving education in contraception and the advantages of the condom as a method of contraception for unmarried couples are discussed.

DSM-III-R classification of psychiatric symptoms in systemic lupus erythematosus.

DSM-III-R criteria applied in the evaluation of 88 systemic lupus erythematosus patients revealed a point prevalence rate of 18.2% for psychiatric disorders, the most common diagnosis being adjustment disorder (11.4%). No patients had disorders compatible with a functional psychosis. Psychiatric morbidity was not associated with increased disease activity, corticosteroid use, brain magnetic resonance imaging abnormalities, or electroencephalogram abnormalities. High scores on a life event scale were associated with psychiatric disorders, suggesting that psychosocial stress is etiologically important. Cognitive testing showed that poor performance on the Stroop Colour-Word Inference Test was associated with psychiatric disorders.
