Background: This study aimed to investigate the epidemiological and clinical aspects of patients with hydatid cyst during 2011 to 2014. Methods: This cross-sectional study was conducted in Khorasan Razavi Prov-ince, the Northeast of Iran, from 2011 to 2014. The study population was all cases with hydatid cyst who diagnosed in governmental and private laboratories, hospitals and health centers (HC) in Khorasan Razavi Province during 2011-14. Results: The prevalence rate of hydatidosis was 1.44 per 100000 individuals. Of 357 cases, 54.9 were women, 40.3 rural, 45.8 housewives, and 3.4 were Afghan. The mean age of women was higher than that of men (39.13�18.9 compared to 34.7�17.9 yr, respectively, P-value=0.025). The highest proportion of cases (39.2) was in the age group of 21-40 yr old. Abdominal pain was re-ported in 42.3 of cases. Liver involvement was the most common localization of hydatid cyst reported in 59.4 of patients, and 8.4 had multiple organ in-volvement. The common diagnosis methods of the disease were radiology (42.3) followed by CT scan (37.8). 45.9 of patients had domestic dog and hygiene principles of washing the vegetables was adhered by 6.7 of patients. Conclusion: The prevalence of human hydatidosis, as a most important neglected disease, should be considered by health policy-makers in public health domain. In addition, educational programs to better recognition of the disease symptoms, and to identify the infection sources are needed in high risk group of population. � 2016, Tehran University of Medical Sciences (TUMS).

Background Traumatic brain injury (TBI) and spinal cord injury (SCI) are increasingly recognised as global health priorities in view of the preventability of most injuries and the complex and expensive medical care they necessitate. We aimed to measure the incidence, prevalence, and years of life lived with disability (YLDs) for TBI and SCI from all causes of injury in every country, to describe how these measures have changed between 1990 and 2016, and to estimate the proportion of TBI and SCI cases caused by different types of injury. Methods We used results from the Global Burden of Diseases, Injuries, and Risk Factors (GBD) Study 2016 to measure the global, regional, and national burden of TBI and SCI by age and sex. We measured the incidence and prevalence of all causes of injury requiring medical care in inpatient and outpatient records, literature studies, and survey data. By use of clinical record data, we estimated the proportion of each cause of injury that required medical care that would result in TBI or SCI being considered as the nature of injury. We used literature studies to establish standardised mortality ratios and applied differential equations to convert incidence to prevalence of long-term disability. Finally, we applied GBD disability weights to calculate YLDs. We used a Bayesian meta-regression tool for epidemiological modelling, used causespecific mortality rates for non-fatal estimation, and adjusted our results for disability experienced with comorbid conditions. We also analysed results on the basis of the Socio-demographic Index, a compound measure of income per capita, education, and fertility. Findings In 2016, there were 27.08 million (95% uncertainty interval [UI] 24.30-30.30 million) new cases of TBI and 0.93 million (0.78-1.16 million) new cases of SCI, with age-standardised incidence rates of 369 (331-412) per 100 000 population for TBI and 13 (11-16) per 100 000 for SCI. In 2016, the number of prevalent cases of TBI was 55.50 million (53.40-57.62 million) and of SCI was 27.04 million (24.98-30.15 million). From 1990 to 2016, the agestandardised prevalence of TBI increased by 8.4% (95% UI 7.7 to 9.2), whereas that of SCI did not change significantly (-0.2% [-2.1 to 2.7]). Age-standardised incidence rates increased by 3.6% (1.8 to 5.5) for TBI, but did not change significantly for SCI (-3.6% [-7.4 to 4.0]). TBI caused 8.1 million (95% UI 6.0-10.4 million) YLDs and SCI caused 9.5 million (6.7-12.4 million) YLDs in 2016, corresponding to age-standardised rates of 111 (82-141) per 100 000 for TBI and 130 (90-170) per 100 000 for SCI. Falls and road injuries were the leading causes of new cases of TBI and SCI in most regions. Interpretation TBI and SCI constitute a considerable portion of the global injury burden and are caused primarily by falls and road injuries. The increase in incidence of TBI over time might continue in view of increases in population density, population ageing, and increasing use of motor vehicles, motorcycles, and bicycles. The number of individuals living with SCI is expected to increase in view of population growth, which is concerning because of the specialised care that people with SCI can require. Our study was limited by data sparsity in some regions, and it will be important to invest greater resources in collection of data for TBI and SCI to improve the accuracy of future assessments. ; Published version ; We acknowledge the funding and support of the Bill & Melinda Gates Foundation.
