Chyle leak following biliary pancreatitis.

Chylous ascites is a rare clinical entity that historically has been accompanied by high mortality due to the association with malignancy. Here we present a case of chylous ascites as a complication of mild pancreatitis in a young woman. We review the literature of similar cases, which revealed four similar cases with a range of outcomes. Treatment options vary from dietary restriction of medium chain fatty acids, total parental nutrition, radiological intervention and surgery.

Does sodium bicarbonate reduce painful voiding after flexible cystoscopy? A prospective, randomized, double-blind, controlled trial.

OBJECTIVE: • To determine if sodium bicarbonate (Ural) reduces painful voiding after flexible cystoscopy. PATIENTS AND METHODS: • 300 patients over 18 years old undergoing elective flexible cystoscopy were enrolled in a randomized, double-blinded, placebo-controlled trial. Patients with active urinary tract infections, indwelling urinary catheters and/or requiring additional procedures such as biopsy and dilatation were excluded. • Painful voiding was quantified using a pain analogue scale from 0 to 10. Pre-existing painful voiding, previous experience with Ural and flexible cystoscopy were recorded. • Flexible cystoscopy was performed to a standard protocol. Patients were randomised after recruitment to receive Ural or placebo (glucose) powder four times a day for two days after the procedure. Trial outcome was assessed by estimating the change in pain incidence and severity from before to two days after by post-procedural questionnaire. RESULTS: • Painful voiding was present in 84 of the 300 patients post flexible cystoscopy (45 of 160 patients receiving Ural; 39 of 140 receiving placebo), but overall mean pain scores were low (1.25; standard deviation 2.4; on a 0-10 scale). • Treatment with Ural compared to placebo was associated with a non-significant reduction in frequency of pain (28.9% vs 31.3%; incidence rate ratio 0.66; 95% CI 0.29-1.46; P = 0.30) and severity of pain (odds ratio 0.72; 95% CI 0.30-1.74; P = 0.47). CONCLUSION: •In the replicable context of low post-cystoscopy pain levels, we believe Ural does not reduce painful voiding after flexible cystoscopy.

Hirschsprung's disease: a regional experience.

BACKGROUND: Hirschsprung's disease (HD) is widely quoted to have an incidence of approximately 1 in 5000 live births. However, it is also known that regional variation in incidence can occur. The aim of this paper was to study the incidence of Hirschsprung's disease in Tasmania and to document a regional experience of HD. METHODS: A retrospective review of all patients with newly diagnosed HD between January 1998 and December 2005 was carried out. Data were extracted from medical records and reported. Tasmanian birth statistics from 1998 to 2005 were obtained from the Australian Bureau of Statistics website and the incidence was calculated. RESULTS: Over the 8-year study period, 14 new cases of HD were identified in Tasmania. The estimated incidence of HD in Tasmania based on this study is 1 in 3429. This incidence is higher than the widely quoted incidence of 1 in 5000, but the difference did not reach statistical significance. Between 2003 and 2005, there was a surge in the number of cases with 11 of 14 cases being derived from these 3 years. No obvious reasons were found to explain this surge in the number of cases. Abdominal distension and vomiting were most common modes of presentation (100 and 71%, respectively). There was delayed passage of meconium in 43%. CONCLUSION: The incidence of Hirschsprung's disease seems higher in Tasmania. The surge in the number of cases is also of interest, although the reasons behind this remain unknown. Delayed passage of meconium was also less common than previously cited.
