Headache is a major worldwide health problem and the second most common type is migraine, with a global prevalence among adults greater than 10%. Migraine mainly affects adults between 25 and 55 years, during the most productive years of life 1 . In Brazil, the prevalence of migraine is estimated to be 15.2% 2 .Lipton et al. 3 demonstrated that migraine is still underdiagnosed and inappropriately treated. They evaluated 4,376 individuals with headache through a computer-assisted telephone interview survey and 536 individuals had migraine, as defined by the International Classification of Headache Disorders -2nd edition 4 (ICHD-2). They found that 48% of migraine sufferers had seen a doctor for headache within the last year and 73% of these reported a physician-made diagnosis of migraine. Of all migraine sufferers, 49% were treated with over-the-counter medications, 23% with prescription medication, 23% with both, and 5% with no medications at all 3 .A study by Bigal et al. 5 with 6,006 participants, conducted in the State of São Paulo, Brazil revealed that migraine was the most prevalent primary headache, accounting for 45.1% of patients reporting headache as their only symptom. In another Brazilian study, the correct diagnosis of migraine by non-specialists was made in only 44.9% of migraine sufferers, The diagnosis of headache was made according to the ICHD-2 criteria. Results: Of the 232 patients, 86% had migraine. The questionnaire showed a sensitivity of 92% (95%CI, 88% to 95%), specificity of 60% (95%CI, 43% to 77%) and a positive predictive value of 93% (95%CI, 89% to 96%). Discussion: Our results were similar to other international studies of the ID-Migraine TM application. The Portuguese version is considered easy to use, and an appropriate screening tool for migraine diagnosis in our sample. Conclusion: Considering the characteristics of our health system, we can infer that this questionnaire would be beneficial in a Brazilian primary care setting; however, more studies are necessary.Keywords: migraine disorders; surveys and questionnaires; headache. O questionário apresentou sensibilidade de 92% (IC de 95% 88% a 95%), especificidade de 60% (IC de 95% 43% a 77%) e valor positivo preditivo positivo de 93% (IC 95 89% a 96%). Discussão: Nossos resultados foram similares a outros estudos mundiais de aplicação do ID-Migraine TM . A versão em Português é considerada de fácil utilização, sendo uma ferramenta adequada para triagem diagnóstica de migrânea em nossa amostra. Conclusão: Considerando as características do nosso sistema de saúde, podemos inferir que este questionário seria útil nos serviços primários de saúde brasileiros, porém mais estudos são necessários.Palavras-chave: transtornos de enxaqueca; inquéritos e questionários; cefaleia.

After the inception of SIP, all professors had an increase in their scientific output; however, this occurred independently of their engagement in SIP disciplines.

Objective The consequences of sleep deprivation in type 1 diabetes (T1D) patients are poorly understood. Our aim was to determine how sleep disorders influence lipid profile and insulin sensitivity in T1D patients. Materials and methods This was a cross-sectional study at a public university hospital. Demographic information and medical histories were obtained during regular scheduled visit of T1D patients to the outpatient clinic. Insulin sensitivity was obtained using the estimated glucose disposal rate (eGDR) formula. Sleep quality was assessed using the Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale and Berlin Questionnaire. Results The adult participants (n = 66, 62% women) had a median age of 28.0 years (interquartile range 21.8-33.0). Six patients (9%) had metabolic syndrome according to the International Diabetes Federation criteria. Thirty patients (46%) were considered poor sleepers according to the Pittsburgh Sleep Quality Index. The LDL-c and total cholesterol levels of poor sleepers were higher than those of good sleepers (103 v. 81; p = 0.003 and 178.0 v. 159.5 mg/dL; p = 0.009, respectively). Three patients (4%) were at high risk of obstructive sleep apnea syndrome (OSAS) according to the Berlin Questionnaire. The eGDR was lower in the group of patients with high probability of having OSAS (6.0 v. 9.1 mg.kg -1 .min -1 ;p = .03). Conclusions Poor subjective quality of sleep and higher risk of OSAS were correlated with a worsened lipid profile and decreased insulin sensitivity, respectively. Therefore, T1D patients with sleep disturbances might have an increased cardiovascular risk in the future.

Medical literature has emphasized the role of scientific research and publications in medical education. This study had the aim to detect the impact of PIC (program of scientific support) upon scientific published production of the professors teaching at Universidade Federal Fluminense. The group comprised 32 professors that participated in the PIC for at least 4 semesters. Each issue published was registered as one "product". Between 1996 and 2003, 8 years were considered for the registration of the "products" by each professor. The mean point of this period was the moment when each professor entered the program. For each professor we counted the products during the 4 years before he entered the program and during the 4 years after this occurred. Finally we summed up the products of all professors for the period before entering the program and had the mean. The same was done for the period after entering the program. Applying the paired t test, two means were reached for the two periods of scientific productivity. The same procedure was followed for two subgroups of professors: masters and doctors. The professors had 25.13 products after and 16.81 before the PIC (P< or =0.001); those with a master degree presented 16.36 products after PIC versus 5.18 before (p< or =0.08); doctors, 29.71 products after versus 22.9 products before PIC (p< or =0.028). The authors concluded that the PIC increased written production of professors, either with degree of master or doctor with relevance for those with degree of master.
