Obstructive Sleep Apnea and Wake-up Stroke - A 12 Months Prospective Longitudinal Study.

BACKGROUND: Wake-up stroke (WUS) are strokes that are noted upon awakening in patients previously going to bed in a normal state of health. The role of sleep abnormalities in WUS is uncertain. The objective was to determine clinical characteristics, respiratory abnormalities during sleep and outcomes in patients with WUS versus non-WUS. METHODS: At baseline, patients with ischemic stroke were examined clinically and with a portable sleep recorder. Apnea-Hypopnea Index greater than or equal to 20 defined a cut-off severity index. At follow-up (3 and 12-months), patients were re-evaluated clinically and with questionnaires: Epworth Sleepiness Scale, Modified Rankin (MR) and Modified Barthel Index Results: Among all (N = 102, 64% male), hypertension (73%), Type 2 diabetes (29.4), heart disease (16.7%), physical inactivity (69.6%), smoking (32.4%) and alcohol consumption (17.6) were found. Apnea-Hypopnea Index (AHI) greater than 5 (92.9%), AHI greater than 15 (44.7%), AHI greater than or equal to 20 (35.3%) and AHI greater than 30 (11.8%) were registered. Cases with and without WUS did not differ regarding polygraphic findings. Long apneas (apnea duration > 20 s) was equally found in patients with WUS (23.1%) and non-WUS (23.7%). Type 2 diabetes mellitus (T2D) was independently associated with WUS (OR = 2.76; CI: 1.10-6.05; P = .03). Prospectively, symptom severity was not different between WUS and non-WUS. Overall, patients with OSA (IAH≥20) evolved with worse functional performance (MR, P = .02). CONCLUSIONS: Wake-up stroke occurred in approximately 1 of 3 of cases. Irrespective of WUS, half of the patients had moderate to severe sleep apnea; those with OSA (AHI≥ 20) evolved with worse functional performance after 1 year. WUS was associated with TDM reinforcing a relationship with cerebral small vessel disease.

Características clínicas e epidemiológicas do paciente adolescente portador de osteossarcoma / Clinical and epidemiological characteristics of adolescent patients with osteosarcoma

O Osteossarcoma (OS) é uma neoplasia maligna que afeta o tecido ósseo, sem causa aparente, acomete mais o esqueleto apendicular, principalmente fêmur e tíbia de crianças e adolescentes. O tratamento consta de cirurgias de ressecção do tumor ou amputação de membros associados à quimioterapia. Quanto mais cedo se descobrir e tratar o OS, e quanto menor for a sua extensão melhor o prognóstico. Objetivo: Conhecer as características clínicas e epidemiológicas do paciente adolescente portador de OS atendido no Hospital do Câncer do Ceará (HCC) no Município de Fortaleza. Para isso foi investigado dados clínicos e epidemiológicos referentes aos pacientes adolescentes (de 10 à 19 anos) portadores de OS. Método: Realizou-se um estudo documental retrospectivo através dos prontuários dos pacientes atendidos nesse hospital no período de Janeiro de 2006 a Dezembro de 2007. Os dados foram coletados através de uma ficha semi-estruturada que constava de questões referentes às características clínicas e epidemiológicas dos pacientes, além dos dados de identificação. Foram selecionados 29 prontuários, sendo utilizados 26 para análise, pois 03 estavam incompletos por abandono de tratamento ou transferência hospitalar. Resultados: O OS foi mais frequente em pacientes do sexo masculino (57,7%), com idade entre 10 e 15 anos (73,1%), de raça afro-descendente (50%) e que residiam no interior (73,1%); 30,8% apresentavam história de câncer na família. O sintoma em comum detectado na queixa principal foi a dor (24 pacientes), seguida do aumento do volume local (20) e trauma prévio (08). O fêmur foi acometido em 65,4% dos casos, com ocorrência de metástase (76,9%), quase sempre ao diagnóstico e sua maioria (15 pacientes) para o pulmão. O tratamento consistia em quimioterapia (96,2%) associada a ressecção cirúrgica (69,2%) e amputação (73,1%) ou substituição por endoprótese. Outras especialidades como a fisioterapia foi prescrita em 42,3% dos casos tendo início no período do pós-operatório (23,1%) e geralmente para tratar as complicações. O paciente portador de OS se caracteriza por ser homem, afro-descendente, proveniente do interior e com antecedentes familiares de câncer. Conclusão: É necessário e importante conhecer as características clínicas e epidemiológicas do paciente portador de OS, redirecionando o olhar dos profissionais de saúde para a importância da inclusão de uma equipe multidisciplinar ao diagnóstico.

Osteosarcoma (OS) is a malignant neoplasia that affects the bone tissue with no known cause. It most commonly affects the appendicular skeleton, mainly the femur and tibia bones, in children and adolescents. The surgery treatment consists of a resection of the tumor or amputation of the affected limb, associated with chemotherapy. The earlier it is diagnosed and treated, and the smaller it is, the better the prognosis will be. Objective: The main objective of this study was to present the clinical characteristics and epidemiology of adolescent patients from the Ceará Cancer Hospital (HCC) in the city of Fortaleza. Clinical and epidemiologic data about these patients, who ranged from the age of 10 to 19 years old, was investigated in order to fulfill our objectives with this study. Method: A retrospective cohort study was developed gathering information from patients' charts from the above-mentioned hospital from the period of January 2006 to December 2007. The data was collected through a semi-structured form that consisted of questions that appraised both the clinical and epidemiological characteristics of the patients, as well as the demographic data. After selecting 29 cases, only 26 were used for the analysis due to either incomplete information, abandonment of treatment, or hospital transference. Results: Our results show that Osteosarcoma was found to be more frequent in male patients (57.7%), in patients between 10 and 15 years old (73.1%), in afro-descendant patients (50%), and in patients that came from more rural areas (73.1%). This study also shows that 30.8% of the patients presented a family history of cancer. The symptom that these patients seemed to have in common was pain (24 patients), followed by an increase of local volume (20 patients), and previous trauma (8 patients). The femur bone was affected in 65.4% of the cases, with occurrence of metastasis (76.9%), almost always during the diagnosis and with the majority (15 patients) to the lungs. The treatment consisted of chemotherapy (96.2%) associated with the surgical resection (69.2%) and amputation (73.1%) or limb replacement. Other treatments such as Physical Therapy were prescribed in 42.3% of the cases, mostly during post-surgery (23.1%), and generally just to treat the complications. Conclusion: This study suggests that the common profile of a patient with Osteosarcoma is male, afro-descendant, coming from the more rural areas and presenting a family history of cancer. In conclusion, this study suggests the importance of knowledge about both clinical and epidemiological characteristics of Osteosarcoma patients, so that there is more regard from health professionals concerning multidisciplinary teamwork at the time of the diagnosis.
