Adult Pancreatoblastoma: An Uncommon Pancreatic Malignancy.

In this report we present a rare case of pancreatoblastoma in an adult patient. Whilst they are amongst the most common malignant pancreatic tumours in children, presentations in adults are exceedingly rare, with a small number of reported cases. Its presentation is often non-specific in terms of clinical examination, and subsequent imaging can show similar findings to those seen in benign neoplasms. This report highlights the difficulty of achieving a diagnosis and subsequent treatment of such an uncommon disease. Biopsy and resultant histology are essential in diagnosis and surgical resection remains the preferred modality of treatment. However, the use of chemotherapy and its efficacy in adults remains unclear, and the prognosis documented in existing literature for adults is worse when compared to paediatric presentations. This case emphasises the need to consider pancreatoblastoma as a differential diagnosis when suspecting pancreatic or abdominal malignancies to achieve early detection and diagnosis, in order to provide optimal treatment and improve patient outcomes.

Pancreatic adenocarcinoma: imaging techniques for diagnosis and management.

Pancreatic cancer is a leading cause of death from cancer but only a minority of patients with pancreatic ductal adenocarcinomas are eligible for curative resection. The increasing role of neoadjuvant therapy provides hope of improving outcomes. However, progress is also reliant on advances in imaging that can identify disease earlier and accurately assess treatment response. Computed tomography remains the cornerstone in evaluation of resectability, offering excellent spatial resolution. However, in high-risk patients, additional magnetic resonance imaging and positron emission tomography-computed tomography may further guide treatment decisions. Conventional computed tomography can be limited in its ability to determine disease response after neoadjuvant therapy. Dual-energy computed tomography and computed tomography or magnetic resonance imaging perfusion studies emerging as potentially better alternatives. Combined with pioneering advances in radiomic analysis, these modalities also show promise in analysing tumour heterogeneity and thereby more accurately predicting outcomes. This article reviews these imaging techniques.

The effect of economic downturns on maternal mortality among pregnancies with abortive outcomes in 81 countries, 1981-2010.

OBJECTIVE: To determine the association between economic downturns and abortion-related maternal mortality in multiple countries over 30 years. METHODS: In a retrospective study, WHO data were obtained for maternal deaths among pregnancies with abortive outcomes between January 1, 1981, and December 31, 2010. Economic data for the same period were obtained from The World Bank. An economic downturn was defined as an annual decline in gross domestic product per head. Multivariate regression-controlling for country-specific differences in infrastructure, population size, and demographic structure-and 5-year lag analyses were performed. RESULTS: Data were available for 81 countries. Abortion-related maternal mortality was significantly increased in years of economic downturns (R=0.0708; 95% confidence interval [CI] 0.0264-0.1151; P=0.0018). The association was sustained for 4 years after an economic downturn (year 1: R=0.0709 [95% CI 0.0231-0.1187], P=0.0037; year 2: R=0.0634 [0.0178-0.1089], P=0.0065; year 3: R=0.0554 [0.0105-0.1004], P=0.0157; year 4: R=0.0593 [0.0148-0.1037], P=0.009). There was an annual 36% increase in deaths associated with unsafe abortion during economic downturn years. CONCLUSION: Economic downturns were associated with increased abortion-related maternal mortality, possibly due to changes in government healthcare spending and service provision. A global economic downturn could impede a reduction in maternal mortality.
