    Presenting features of primary angle-closure glaucoma in patients of mixed ethnic background
    (1993) SALMON, J
    The relative frequency with which patients present with acute or chronic angle-closure glaucoma depends on their ethnic background. In order to examine the presenting features and effects of primary angle-closure glaucoma in people of mixed ethnicity, we reviewed all «coloured» patients who presented to Groote Schuur Hospital with this diagnosis during a 5-year period. Of the 92 patients, 33 (36%) presented with acute angle-closure glaucoma and 59 (64%) with chronic angleclosure glaucoma. The level of intra-ocular pressure on presentation correlated well with the number of quadrants of angle closure (correlation coefficient: r=0,73, P<0,001). When individual eyes were assessed, a mean cup/disc ratio of ≥0,8 was present in 35% (65/184) and glaucomatous visual field loss was present in 56,5% (104/184).The relative frequency with which patients present with acute or chronic angle-closure glaucoma depends on their ethnic background.

    Single-dose benzathine penicillin in infants at risk of congenital syphilis : results of a randomised study
    (1997) Radcliffe, M; Meÿer, M; Roditi, D; Malan, A
    OBJECTIVE: To determine the efficacy of single-dose benzathine penicillin G in infants at high risk of congenital syphilis. DESIGN: Randomised study comparing benzathine penicillin with no therapy. SETTING: Peninsula Maternal and Neonatal Service, Cape Town. SUBJECTS: Asymptomatic infants born to mothers with untreated syphilis whose VDRL titre was 32 or more. OUTCOME MEASURES: The number of cases of congenital syphilis was determined by results of IgM Western blots and follow-up VDRL titres. RESULTS AND CONCLUSIONS: Of 8 patients followed up in the non-treatment group, 4 had congenital syphilis while 0/11 had the disease (P = 0.035) in the group receiving benzathine penicillin. Although the exact failure rate is unknown, benzathine penicillin is effective in preventing symptomatic congenital syphilis when administered to high-risk newborns.

    The 'dop' system around Stellenbosch--results of a farm survey
    (1998)
    OBJECTIVES: To document the number of farms operating a 'dop' system (payment of workers with alcohol instead of wages), to estimate the number of farm workers affected, to describe how the system operated and to characterise adverse social conditions on the farms. POPULATION: Farms served by the mobile clinics of the Cape Metropolitan Council's Health Department in the Stellenbosch area. METHODS: Cross-sectional prevalence survey. Nurses collected data from patients attending mobile clinics. RESULTS: A prevalence of 9.5% was detected in respect of farms operating the dop system, with an estimated 780 workers affected. The most common practice was a daily provision of 750 ml wine to male workers. Social conditions on the farms in question were poor and wages were low. Child malnutrition was the most common health problem identified. CONCLUSION: The dop system, although illegal, has been documented to occur in the Stellenbosch area. Programmes to address the dop system and alcohol abuse, based on a primary health care approach, are a priority in the rural areas of the Western Cape.
