Alterações cardíacas em pacientes durante o primeiro ano de hemodiálise crônica: foco em preditores de fibrilação atrial / Cardiac changes in patients during the first year of chronic hemodialysis: focus on predictors of atrial fibrillation

Objetivos: Detecção precoce de alterações cardíacas, em especial de preditores de fibrilação atrial (FA), em pacientes renais crônicos dialíticos, permitem condutas terapêuticas que podem impactar na morbimortalidade cardiovascular desses pacientes. Descrevemos alterações elétricas e estruturais cardíacas nos pacientes durante o 1º ano de hemodiálise (HD). Métodos: Estudo observacional, transversal, prospectivo, em pacientes entre 20 e 80 anos, renais crônicos, pertencentes a serviços públicos de São Paulo, divididos pelo tempo de início de hemodiálise: grupo 1: 1 a 6 meses; grupo 2: 7 a12 meses. Coletados dados sociodemográficos, mórbidos, eletrocardiograma de repouso, Holter 48h, ecocardiograma transtorácico e exames de sangue pré e pós hemodiálise ( função renal, eletrólitos, bicarbonato e inflamatórios). Analisados por teste T student e Qui-quadrado. Resultados: 73 pacientes, hipertensos, predomínio homens, quinquagenários, escolaridade fundamental, brancos, não solteiros, procedentes da região sudeste metropolitana, com multimorbidades e polifarmácia. Grupo 2 apresentou maior idade (p=0,007), morbidades (p=0,04), medicações (p=0,02), preditores de FA caracterizados por extrassístoles ventriculares ( p=0,02), aumento dos volumes e diâmetros ventriculares e átrio esquerdo (todos p≤0,001), alteração do bicarbonato pré e pós hemodiálise (p<0,01). Grupo 1 apresentou maiores alterações eletrolíticas pós hemodiálise (p≤0,03). Conclusão: Além da hipertensão arterial, tempo de hemodiálise, acidose metabólica próxima dos limites de referência, associaram-se precocemente à progressiva disfunção sisto-diastólica de câmaras esquerdas cardíacas e preditores de fibrilação atrial, em especial o volume sistólico final, predominantemente no 2º semestre do início de hemodiálise. Sugere-se Holter e Ecocardiograma a partir do 7º mês de hemodiálise e controles mais rígidos de acidose para essa população.

Objectives: Early detection of cardiac alterations in chronic renal patients on hemodyalisis (HD), especially atrial fibrillation (AF) predictors, allows therapeutic approaches that can impact their cardiovascular prognosis. We describe electrical and structural cardiac alterations in patients during the 1st year of hemodyalisis. Methods: Observational, cross-sectional, prospective study. Chronic kidney patients on dyalisis aged between 20 and 80 years, wihout atrial fibrillation, from public hemodyalisis services were divided by the time of hemodyalisis onset: group 1: 1 to 6 months; group 2: 7 to 12 months. Sociodemographic and morbid data, electrocardiogram at rest, Holter 48h, transthoracic echocardiogram and pre and post hemodialysis blood tests (kidney function, electrolytes and inflammatory tests) were collected. Data analyzed by Chi-square and Student T tests. Results: 73 hypertensive patients, predominantly men, aged in their fifties, elementary school, white, not single, from the metropolitan southeast region, with multimorbidities and polypharmacy were analyzed. Group 2 presented more age (p<0.01), morbidities (p=0.04), medications (p=0.02), atrial fibrillation, predictors especially ventricular extrasystoles (VES, p=0.02), increased left venticular and atrium volumes and diameters (all p≤0.001) and lower bicarbonate before and after hemodyalisis (both p≤0,01). Group 1 presented more changes in eletrolytes (p≤0.03). Conclusion: In addition to arterial hypertension, hemodyalisis duration was associated to systolic and diastolic dysfunction of the left cardiac chambers, atrial fibrillation predictors especially end-systolic volume (ESV) and mild acidosis, in the 2nd semestre predominantly. Holter and echocardiography are suggested from the 7th month of hemodyalisis onset and tighter metabolic control in this population

Reconstrucción palpebral inferior después de la escisión de tumores malignos / Lower eyelid reconstruction after excision of malignancies

Se presentan 4 casos clínicos de pacientes de 46-76 años con carcinomas basocelular y escamoso de párpado inferior, diagnosticados en la consulta oftalmológica del Hospital General Docente "Dr. Juan Bruno Zayas Alfonso". A los afectados se le realizó tarsectomía parcial o total con reconstrucción palpebral mediante colgajos miocutáneos en islas de área cigomática y músculo nasal. Los resultados tanto funcionales como estéticos fueron óptimos y se corroboró la efectividad de los colgajos antes citados.

Four case reports of patients of 46-76 years with squamous-cell carcinoma and basal-cell epithelioma of lower eyelid was described, diagnosed in the ophthalmology department of "Dr. Juan Bruno Zayas Alfonso" Teaching General Hospital. In those affected a partial or total tarsectomy with eyelid reconstruction by means of island myocutaneous flaps of zygomatic area and nasal muscle was performed. The functional and aesthetic results were optimal and the effectiveness of these flaps was confirmed.

Caracterización clinicoepidemiológica de pacientes con tumores palpebrales malignos / Clinical and epidemiological characterization of patients with malignant eyelid tumors

Se efectuó un estudio observacional, descriptivo y transversal de 61 pacientes con tumores palpebrales malignos, atendidos en la consulta de Oftalmología del Instituto Nacional de Oncología y Radiobiología de Ciudad de La Habana, durante el 2011, a fin de caracterizarles según variables clinicoepidemiológicas de interés para la investigación. En la serie, los más afectados fueron el sexo masculino (68,6 por ciento) y los pacientes de piel blanca (86,9 por ciento); predominaron el grupo etario de 61-70 años (37,0 por ciento), el carcinoma basocelular como el tumor palpebral maligno más frecuente (73,8 por ciento) y la agricultura como la labor fundamental que realizaban los enfermos (67,2 por ciento)

An observational, descriptive and cross-sectional study was conducted in 61 patients with malignant eyelid tumors, treated at the Ophthalmology Department of the National Institute of Oncology and Radiobiology, Havana, during 2011, in order to characterize them according to clinical and epidemiological variates of interest to research. Male sex (68.6 percent) and white patients (86.9 percent) were the most affected in the series. Also, the age group of 61-70 years (37.0 percent), basal cell epithelioma as the most frequent malignant eyelid tumor (73.8 percent) and agriculture as the essential work performed by patients (67.2 percent) prevailed
