ObjectivesBeing one of the main causes of morbidity and mortality in developed countries, ischaemic heart disease's (IHD) incidence and mortality present clear differences between and within countries. Several authors already proposed possible explanations based on the demography, environmental factors, diet and level of urbanisation. This study reflects the Portuguese reality concerning IHD, by analysing the geographical distribution of hospital admissions and mortality due to this condition, in Portugal, and its association with demography, economical factors and the distribution of healthcare resources at the regional level.DesignEcological study.SettingData from all Portuguese Public Hospitals were obtained using the National Registry of Hospital Admissions, between 2000 and 2007, and data on demography, economical factors and health resources distribution were obtained from the National Institute of Statistics.ParticipantsAggregated statistics on hospital admissions and mortality were computed for 278 counties based on almost 200 000 admissions.Primary and secondary outcome measuresMortality rate; hospital admissions rate.ResultsThe geographical distribution of non-adjusted mortality and hospital admission showed an inner/coastal pattern but no North/South gradient was clear. Counties with higher economical development had significantly higher mortality and admission rates. However, healthcare resources distribution was not significantly associated with IHD hospital admission and mortality. When adjusted for age, gender, economic development and health resources distribution, there was still unexplained geographical variation both in hospital admissions and mortality rates.ConclusionA pattern in the geographic distribution of incidence and mortality of IHD was clear even after the adjustment for age and gender. Economical variables were the ones presenting the strongest association. These types of analysis may be very helpful for the definition of health policies, in particular to identify priority regions for disease prevention and guidelines for healthcare resources distribution.

Introduction:The disruption of esophageal motility that characterizes achalasia typically provokes dysphagia, pain, loss of weight and malnutrition. Therefore, patients frequently report a reduction in quality of life and negative emotional states. Laparoscopic Heller myotomy proved to be an effective therapy, enabling the resumption of good quality of life. Material and Methods:The authors studied 45 patients previously submitted to laparoscopic Heller myotomy. Postoperative evaluation was performed using a customized version of the achalasia disease-specific quality of life questionnaire. Quality of life and the presence of depressive and anxiety symptoms were assessed using the Portuguese versions of the Medical Outcomes Study SF-36 and the Hospital Anxiety and Depression Scale. Conclusion:This study demonstrates that the Heller myotomy is associated with a good quality of life in patients with achalasia and strengthens the evidence that this is a safe and reliable procedure.
