An arteriovenous fistula (AVF) remains the best choice of vascular access (VA) for hemodialysis (HD). The aim of the study was to determine the factors associated with the achievement of adequate blood flow (BF) of AVFs at the 4th week after creation. Created AVFs in 63 patients with chronic kidney disease (CKD) stage 4/5 and CKD stage 5 on hemodia...

We present the case of a young woman with abnormal vaginal bleeding two weeks after an abdominal myomectomy. The intervention was initially considered uncomplicated. Transvaginal sonography detected a pulsatile cystic area, just above the endometrium in the anterior wall of the lower uterine segment. Color Doppler analysis revealed the communicatio...

Impaired fetal growth owing to placental insufficiency is a major contributor to adverse perinatal outcomes. No intervention is available that improves outcomes by changing the pathophysiologic process. Monitoring in early-onset fetal growth restriction (FGR) focuses on optimizing the timing of iatrogenic preterm delivery using cardiotocography and...

Since its initial description in 1996 by Yii and Niranjan, the internal pudendal perforator flap (also known as the Singapore flap, the gluteal fold flap, and the lotus petal flap) has become a workhorse in perineal soft tissue reconstruction. In 2001, Hashimoto described the presence of three to five perforators in the perineal anogenital triangle...
Background This study had a threefold aim: to test the value of stakeholder involvement in HTA to reduce evidence gaps and interpret findings; and to assess a medical device by applying the EUnetHTA Core Model (CM) in South Africa and thus ultimately provide a first overview of evidence for potential widespread adoption of the technology in a prima...

BackgroundErectile dysfunction (ED) is common among ageing men because of associated underlying risk factors which are peculiar to this category of patients. Endothelial dysfunction and replacement of cavernosal smooth muscles by collagen fibres are common in older men, making them prone to ED. It is either vasogenic, neurogenic, hormonal, cavernos...

The assessment of fetal blood flow using Doppler waveform can be used to identify placental insufficiency, and hence is a tool to identify fetuses at risk of stillbirth due to fetal growth restriction (FGR). In South Africa the largest category of perinatal deaths is 'unexplained intrauterine death'. The majority of the mothers are clinically healt...

BackgroundFetal sex is known to affect pregnancy outcomes. In current clinical practice, monitoring of fetal well-being is based on Doppler ultrasound measurements of major placental and fetal vessels. The objective of this study was to investigate the effect of fetal sex on Doppler parameters throughout gestation in healthy pregnancy.MethodsA pros...

Aim: To determine whether differences in joint and tendon stiffness as measured by ultrasound shear wave elastography are present in breast cancer patients with aromatase inhibitor-associated arthralgias compared to age-comparable healthy control women. Methods: Postmenopausal women with stage I–III breast cancer who were taking adjuvant aromatase ...
