Intragastric balloons are used as a temporary restrictive method in obesity to induce weight loss. They are typically recommended when patients have mild obesity and have failed traditional first line treatments of diet, exercise and behaviour modification. We report a case of a 45-year-old female who presented with nausea, vomiting and abdominal pain two weeks following an uncomplicated insertion of an intragastric balloon. Following investigation, she was found to have a gastric outlet obstruction which required endoscopic removal of the balloon. While a rare occurrence, gastric outlet obstruction as seen in this case, highlights the importance of early recognition in order to proceed with swift diagnosis and intervention in order to prevent significant morbidity such as ischaemia and perforation.

Mucormycosis is a rare and highly aggressive fungal infection, with a potential to reach its fulminant phase rapidly. We report a case of a 73-year-old immunocompromised vasculopath with cutaneous mucormycosis. The disease resulted in eventual death despite aggressive surgical debridement, revascularization of his limb and amphotericin-B. This case highlights the need to recognize this disease early as a differential of a necrotic ulcer, to prevent a potentially avoidable fatality.

Juvenile melanoma remains a rarity in Western Australia despite a very high incidence of adult melanoma. Unlike in adults, no definitive risk factors have been established. A significant proportion of this cohort had a pre-existing naevus and while most melanomas occurred in sun-exposed areas in light-skinned individuals the association between sunburn and melanoma was not strong.

Background: Early detection of a postoperative pancreatic fistula (POPF) may improve outcomes after pancreaticoduodenectomy (PD). The aim was to assess the role of postoperative drain fluid amylase (DFA) and lipase (DFL) measurements as a predictive indicator in the development of POPF. Methods: This retrospective cohort study included all PD procedures performed between 2009 and 2017 at Fremantle and Fiona Stanley Hospital in Western Australia. The DFA and DFL measurements on postoperative day (POD) three and five were correlated with the development of POPF. Results: A total of 169 patients were included in this study with a mean age of 64 AE 11.3 years. Of these, 17 (10.1%) developed a clinically significant POPF. In patients who had both a DFA and DFL measured on both POD 3 and 5, DFA and DFL was significantly higher in patients who developed POPF than those who did not (P < 0.001). In a receiver operating characteristic curve analysis, the most accurate test was POD 3 DFL measurement with an AUC 0.85 (CI 0.75-0.95, P < 0.001). A negative predictive value of 97.4% was observed. DFA and DFL were concordant in 89.2% of cases on POD 3 and 90.6% of cases on POD 5. Conclusion: In this study, DFL measured on POD 3 as a single measurement appears to carry the most benefit in prediction of clinically significant POPF. Reduction to a measurement on this day may lead to a reduction in cost, earlier drain removal and earlier identification of high-risk patients. *P < 0.05 is considered statistically significant.Optimal threshold values obtained via Youdan index.
