Tratamento cirúrgico do blefaroespasmo essencial: relato de dois pacientes Surgical treatment of blepharospasm: report of two patients

Blefaroespasmo essencial pode ser tratado por diversas opções terapêuticas: clínicas em que se destaca entre outros o uso da toxina botulínica com suas vantagens e limitações, e algumas opções de tratamento cirúrgico. A técnica cirúrgica proposta por Gillum e Anderson oferece uma alternativa a pacientes resistentes ao tratamento clínico ou que durante a evolução da doença apresentem complicações secundárias. São analisados dois casos em que se indicou a miectomia dos músculos orbicular da pálpebra, prócero e corrugador do supercílio associados à blefaroplastia e ritidoplastia frontal por terem apresentado diminuição da resposta ao tratamento clínico. Ambos obtiveram bons resultados, retornando às suas atividades normais.<br>Essential blepharospasm can be approached by several types of treatment: clinical in which the most important is the botulinum toxin with advantages and limitations; and some options of surgical treatment. The surgical technique described by Gillum and Anderson offers an alternative to patients resistant to the clinical treatment or with secondary complications. Two cases are analysed. Myectomy of all accessible orbicularis oculi, procerus and corrugator superciliaris muscle associated with blepharoplastic surgery and frontal lifting was indicated due to poor answer to clinical treatment. The results were satisfactory and both patients returned to their normal activities

Global, regional, and national incidence, prevalence, and years lived with disability for 301 acute and chronic diseases and injuries in 188 countries, 1990-2013:a systematic analysis for the Global Burden of Disease Study 2013

Background Up-to-date evidence about levels and trends in disease and injury incidence, prevalence, and years lived with disability (YLDs) is an essential input into global, regional, and national health policies. In the Global Burden of Disease Study 2013 (GBD 2013), we estimated these quantities for acute and chronic diseases and injuries for 188 countries between 1990 and 2013. Methods Estimates were calculated for disease and injury incidence, prevalence, and YLDs using GBD 2010 methods with some important refinements. Results for incidence of acute disorders and prevalence of chronic disorders are new additions to the analysis. Key improvements include expansion to the cause and sequelae list, updated systematic reviews, use of detailed injury codes, improvements to the Bayesian meta-regression method (DisMod-MR), and use of severity splits for various causes. An index of data representativeness, showing data availability, was calculated for each cause and impairment during three periods globally and at the country level for 2013. In total, 35 620 distinct sources of data were used and documented to calculated estimates for 301 diseases and injuries and 2337 sequelae. The comorbidity simulation provides estimates for the number of sequelae, concurrently, by individuals by country, year, age, and sex. Disability weights were updated with the addition of new population-based survey data from four countries. Findings Disease and injury were highly prevalent; only a small fraction of individuals had no sequelae. Comorbidity rose substantially with age and in absolute terms from 1990 to 2013. Incidence of acute sequelae were predominantly infectious diseases and short-term injuries, with over 2 billion cases of upper respiratory infections and diarrhoeal disease episodes in 2013, with the notable exception of tooth pain due to permanent caries with more than 200 million incident cases in 2013. Conversely, leading chronic sequelae were largely attributable to non-communicable diseases, with prevalence estimates for asymptomatic permanent caries and tension-type headache of 2·4 billion and 1·6 billion, respectively. The distribution of the number of sequelae in populations varied widely across regions, with an expected relation between age and disease prevalence. YLDs for both sexes increased from 537·6 million in 1990 to 764·8 million in 2013 due to population growth and ageing, whereas the age-standardised rate decreased little from 114·87 per 1000 people to 110·31 per 1000 people between 1990 and 2013. Leading causes of YLDs included low back pain and major depressive disorder among the top ten causes of YLDs in every country. YLD rates per person, by major cause groups, indicated the main drivers of increases were due to musculoskeletal, mental, and substance use disorders, neurological disorders, and chronic respiratory diseases; however HIV/AIDS was a notable driver of increasing YLDs in sub-Saharan Africa. Also, the proportion of disability-adjusted life years due to YLDs increased globally from 21·1% in 1990 to 31·2% in 2013. Interpretation Ageing of the world's population is leading to a substantial increase in the numbers of individuals with sequelae of diseases and injuries. Rates of YLDs are declining much more slowly than mortality rates. The non-fatal dimensions of disease and injury will require more and more attention from health systems. The transition to non-fatal outcomes as the dominant source of burden of disease is occurring rapidly outside of sub-Saharan Africa. Our results can guide future health initiatives through examination of epidemiological trends and a better understanding of variation across countries
