Graves' disease presenting as pseudotumor cerebri: a case report
Ester Coutinho, Ana M Silva, Cláudia Freitas, Ernestina Santos
Journal of Medical Case Reports , 2011, DOI: 10.1186/1752-1947-5-68
Abstract: We report the case of a 31-year-old Luso-African woman with clinical symptoms and laboratory confirmation of Graves' disease that presented as pseudotumor cerebri.This is a rare form of presentation of Graves' disease and a rare cause of pseudotumor cerebri. It should be remembered that hyperthyroidism is a potential cause of pseudotumor cerebri.Pseudotumor cerebri (PTC) is an entity characterized by elevated intracranial pressure with normal cerebrospinal fluid (CSF) and no structural abnormalities detected on brain MRI scans. The neurological symptoms and signs can be totally attributed to intracranial hypertension, and these include headaches, transient visual obscurations, visual loss and intracranial tinnitus, papilledema being the hallmark of PTC. This syndrome includes both idiopathic and secondary causes. Common secondary causes include endocrine pathologies. Thyroid disturbances have a unique correlation, since hypothyroidism, hyperthyroidism and thyreostimulin suppression hormone therapy have all been reported in association with this disorder. Hyperthyroidism is very rarely associated with the disorder and only three case reports [1-3] have been published to date, one of them [3] in association with hypovitaminosis A.A 31-year-old Luso-African woman who was a law student was admitted to our department. She was slim (body mass index (BMI) of 22), with no relevant medical history and not taking any drugs. She presented with progressive symptoms: persistent headache and vomiting that had lasted for six months accompanied by visual disturbance ('blurred vision') in the last few days. She also stated she had pain with ocular movements and neck stiffness. She had also shown clinical symptoms and signs (tremor, diarrhea, tachycardia, heat intolerance and exophthalmus) for the past five months suggestive of hyperthyroidism. On neurological examination she presented with bilateral papilledema and nuchal rigidity. Goldmann visual fields showed bilateral enlargement

Abstract: probabilistic record linkage methodology has been increasingly used to ascertain outcomes in cohort studies. however, only a few studies have evaluated its accuracy. the aim of this study was to evaluate the accuracy of probabilistic record linkage methodology to ascertain deaths in a cohort of 250 elderly people hospitalized for fractures caused by falls. the vital status of cohort members was determined through household visits conducted at one and six months after hospital admission. record linkage was used to link records from the cohort to the rio de janeiro state mortality database. deaths identified by the latter process were compared to the results obtained by active follow-up (gold standard). the vital status of 20 cohort members could not be determined by active follow-up. among the remaining 230, 60 died within 180 days after hospital admission. record linkage had a sensitivity of 85.5%, specificity of 99.4%, positive predictive value of 98.1%, and negative predictive value of 94.9%. in conclusion, probabilistic record linkage appears to be a useful tool for identifying deaths in cohort studies conducted in brazil.

Abstract: Poucos estudos avaliaram a acurácia do método do relacionamento probabilístico de registros para a identifica o de desfechos em estudos de coorte. O objetivo deste estudo foi avaliar a acurácia do método para a identifica o de óbitos em uma coorte de 250 idosos hospitalizados por fratura decorrente de queda. O estado vital dos membros da coorte foi determinado por meio de visitas domiciliares realizadas um e seis meses após a hospitaliza o. O método probabilístico foi usado para relacionar os registros da coorte (padr o-ouro) com aqueles da base de mortalidade do Estado do Rio de Janeiro, Brasil, visando à identifica o de óbitos. O estado vital de vinte membros da coorte n o p de ser determinado. Entre os 230 restantes, 60 faleceram dentro do período de 180 dias após a admiss o hospitalar. O método apresentou uma sensibilidade de 85,5%, uma especificidade de 99,4%, um valor preditivo positivo de 98,1% e um valor preditivo negativo de 94,9%. Concluindo, o relacionamento probabilístico de registros parece ser uma ferramenta útil para a identifica o de óbitos em estudos de coorte realizados no Brasil.

Abstract: the purpose of this study was to evaluate the feasibility of establishing a surveillance system for diabetes mellitus in the elderly using data sources on morbidity (hospital and outpatient data) and mortality and the capture-recapture methodology. log-linear models were adjusted for the entire sample and for gender and age strata. seven hundred and forty patients were identified in the three combined sources. the model selected for the whole sample when the first linkage strategy was deployed estimated a total of 22,925 cases (90%ci: 11,354-57,269), an implausibly high figure that suggested a strong final negative dependency between sources. age and gender stratification led to more plausible point values, which nevertheless still lacked precision. the only subset that displayed precise values was the 60-to-69-year-old female stratum (1,290 cases; 90%ci: 779-2,476). the factors that possibly explain these results are: (a) the low number of cases originated in the specialized and more complex facilities in the outpatient data source and (b) overall underreporting of diabetes mellitus cases.

Abstract: capture-recapture methodology is used in ecology to estimate the total size of wild animal populations. this method can be used in epidemiology to estimate the incidence and prevalence of communicable and non-communicable diseases in a relatively inexpensive and quick way. surveillance systems based on the use of this methodology are a potential alternative for monitoring non-communicable diseases in brazil. this paper presents a brief review of fundamental capture-recapture methodology and its applications to epidemiology. we also present a theoretical model for implementation of a diabetes mellitus surveillance system in the elderly using publicly available morbidity and mortality data sources and the capture-recapture methodology.
