- ItemRetrospective review of the medical management of ectopic pregnancies with methotrexate at a South African tertiary hospital(Health and Medical Publishing Group, 2014) De Waard, L.; Butt, J. L.; Muller, C. J. B.; Cluver, C. A.Background. An ectopic pregnancy can be a life-threatening condition. Early diagnosis with ultrasonography and quantitative betahuman chorionic gonadotrophin (β-hCG) measurement has improved early and accurate diagnosis and treatment. Medical management with methotrexate internationally has a success rate of up to 93%, but there is a paucity of data on this treatment option in developing countries. Objective. To determine the success of methotrexate treatment for ectopic pregnancies at a referral hospital in a developing country. This non-surgical, outpatient treatment seems a good option in hospitals with an ever-rising pressure on bed occupation and long waiting lists for emergency surgery. Methods. A 5-year retrospective audit was performed on 124 patients treated for ectopic pregnancies with methotrexate at Tygerberg Hospital, Cape Town, South Africa. Results. With success defined as a β-hCG level of <15 IU/L without requiring surgical intervention, the success rate was 44%. Fifteen per cent of medically managed patients required surgery. The remaining 41% were lost to follow-up. One patient had a major adverse outcome with a ruptured ectopic and required 2 units of blood, resuscitation and emergency laparotomy. Conclusion. Medical management of ectopic pregnancies is a safe and effective management option, as proven by international data, but at Tygerberg Hospital the safety of this treatment modality cannot be guaranteed because of poor follow-up. Improvement in patient selection with consideration of predictors of success and thorough counselling, as well as full informed consent, is recommended before using this treatment modality. A new follow-up system should be developed at Tygerberg Hospital to guarantee patient safety.
- ItemVulvar cancer is not a disease of the elderly : treatment and outcome at a tertiary referral centre in South Africa(Health & Medical Publishing Group, 2017) Butt, J. L.; Botha, M. H.Background. An increase in vulvar cancer in young women is attributed to infection with oncogenic human papillomavirus (HPV). South Africa (SA) has a high prevalence of HPV, and it was therefore hypothesised that women with vulvar cancer here would be younger than in high-income countries (HICs). Objective. To describe age, cancer stage, treatment and outcome of patients with vulvar cancer at a tertiary referral centre in SA. Methods. In a retrospective observational study, patient records of women diagnosed with vulvar cancer between 2001 and 2014 were reviewed and demographic and surgical details captured. Histology results of vulvar biopsies and resected specimens were checked for HPV changes, koilocytes and usual-type vulval intraepithelial neoplasia. Patients were restaged using the International Federation of Gynecology and Obstetrics (FIGO) 2009 staging system to allow for comparison of outcomes. Five-year disease-specific survival probability curves were generated using Kaplan-Meier analysis. Results. The mean age of the 180 patients in the study was 52.5 years. Those who had documented HPV changes on histological specimens had a mean age of 50.4 years. More than 50% of the patients had advanced-stage disease, and 62.7% were treated with primary surgery. Five-year disease-specific survival probabilities were similar to those reported in the literature. Conclusions. Vulvar cancer should not be regarded as a disease of the elderly in SA, as women with vulvar cancer are 10 - 15 years younger than in HICs. A large proportion of patients present with advanced-stage disease. Health professionals should be alert to vulvar lesions, especially in women with abnormal Pap smears, to reduce the morbidity and mortality of this disease.
