BACKGROUND/PURPOSE To define the clinical characteristics and surgical management of intracaval involvement in patients enrolled in the UKW3 trial (1991-2001), which recommended elective preoperative chemotherapy for such cases. METHODS Cases were identified from preoperative imaging and surgical trial forms. These asked specific questions about whether(More)
AIM The purpose of this study was to assess the effectiveness of routine staged reduction and closure at the bedside, using preformed silos with no general anesthesia (PSnoGA), compared to emergency operative fascial closure (OFC) under general anesthesia for gastroschisis (GS). METHODS A retrospective matched case-control analysis of neonates with GS was(More)
Breast cancer incidence differs by ethnicity in New Zealand (NZ) with Māori (the indigenous people) women having the highest rates followed by Pakeha (people primarily of British/European descent), Pacific and Asian women, who experience the lowest rates. The reasons for these differences are unclear. Breast density, an important risk factor for breast(More)
PURPOSE To determine if patients receiving preoperative chemotherapy with vincristine and actinomycin D for non-metastatic Wilms' tumour have a more advantageous stage distribution and so need less treatment compared to patients who have immediate nephrectomy, without adversely affecting outcome. METHODS Between 1991 and 2001, a total of 205 patients with(More)
BACKGROUND We previously reported our short-term experience of foreskin preputioplasty as an alternative to circumcision for the treatment of foreskin balanitis xerotica obliterans (BXO). In this study, we aimed to compare this technique with circumcision over a longer period. METHODS Between 2002 and 2007, boys requiring surgery for BXO were offered(More)
BACKGROUND Repeat infection with Chlamydia trachomatis following treatment is common and increases the risk of sequelae. Despite clinical guidelines recommending rescreening within 3 months of treatment, rescreening rates remain low. We undertook a systematic review to identify studies that compared rates of rescreening for repeat chlamydial infection(More)

The aim of this study was to explore physical activity habits and preferences in the month leading up to a first-ever stroke, and to determine whether participants were aware of the link between stroke and physical activity.

We describe the clinical, endoscopic, and histological features of all cases of Barrett's esophagus (BE) diagnosed at our institution between 2000 and 2007 following the criteria of the British Society of Gastroenterology. This society defines BE as a segment of columnar metaplasia (CLO) (whether intestinalized or not) of any length, visible endoscopically(More)
Waist circumference is a measure of potential value in paediatrics, given its relation to cardiovascular risk in adults. However, three different methods of measurement are currently in use, giving potential for confusion. This study was undertaken to assess consistency across the measures in a population of overweight and normal weight children. We found(More)
We present a case of a term neonate with hypovolemic shock after spontaneous vaginal delivery. Hemodynamic instability persisted despite resuscitation with packed red cells, fresh frozen plasma, and platelets. An ultrasound scan at 48 hours after birth followed by a computed tomographic scan demonstrated a splenic lesion and hemoperitoneum. She underwent an(More)
