ABSTRACT

INTRODUCTION AND HYPOTHESIS: Patients with genital prolapse and occult stress urinary incontinence (OSUI) are typically treated with prolapse surgery and anti-incontinence surgery based on either a one-step approach or a two-step approach. The aim of our study was to determine whether anti-incontinence surgery is necessary based on the occurrence of OSUI in a study cohort with a long follow-up period. METHODS: Prolapse surgery was performed using a vaginal approach. Preoperatively, a stress test, a pad test and an assessment of the urodynamics were performed with and without prolapse reduction. Over a follow-up period of 2-8 years, the patients with preoperative evidence of OSUI underwent urogynaecological examinations, stress tests and pad tests. RESULTS: Of 113 patients with preoperative evidence of OSUI, 57 (50.4 %) were followed up for an average of 5.7 years (range 2-8) after prolapse surgery. Of 57 patients, 16 (28.1 %) had objective and/or subjective stress urinary incontinence (SUI) during the follow-up period, but only 3 patients (5.3 %) required subsequent tension-free vaginal tape (TVT) surgery. In 17 of 57 patients (29.8 %), prolapse recurred. CONCLUSIONS: Despite the preoperative evidence of OSUI, the manifestation of SUI rarely occurs, with 28.1 % of patients experiencing SUI over long-term follow-up after vaginal prolapse surgery. Anti-incontinence surgery was necessary in only three cases (5.3 %). These results indicate that with the one-step approach, 54 of 57 patients (94.7 %) would have received prophylactic anti-incontinence surgery unnecessarily. In conclusion, we recommend the two-step approach in the management of vaginal prolapse surgery in patients with OSUI.

ABSTRACT

BACKGROUND: In Tanzania, drug-resistant malaria parasites are an increasing public health concern. Because of widespread chloroquine (CQ) resistance Tanzania changed its first line treatment recommendations for uncomplicated malaria from CQ to sulfadoxine-pyrimethamine (SP) in 2001. Loss of SP sensitivity is progressing rapidly. SP resistance is associated with mutations in the dihydrofolate reductase (pfdhfr) and dihydropteroate synthase (pfdhps) genes. METHODS: In samples from 86 patients with uncomplicated Plasmodium falciparum malaria from Mbeya and Matema, Mbeya region, south-western Tanzania, the occurrence of mutations was investigated in the pfcrt and pfmdr1 genes which are associated with CQ resistance and in pfdhfr and pfdhps, conferring SP resistance, as well in cytb which is linked to resistance to atovaquone. RESULTS: Pfcrt T76 occurs in 50% and pfmdr1 Y86 in 51.7%. Pfdhfr triple mutations coexisting with pfdhps double mutations were detected in 64.3% of the P. falciparum isolates. This quintuple mutation is seen as a possible predictive molecular marker for SP treatment failure. Mutations of the cytb gene were not detected. CONCLUSION: These findings of a high prevalence of mutations conferring SP resistance correspond to data of in vivo SP efficacy studies in other regions of Tanzania and underline the recommendation of changing first-line treatment to artemisinin-based combination therapy.
