Perfil clínico de pacientes dermatológicos encaminhados para avaliação oftalmológica / Clinical profile of dermatological patients referred to ophthalmological evaluation

RESUMO Objetivo: Analisar o perfil clínico de pacientes em acompanhamento dermatológico encaminhados para avaliação oftalmológica. Métodos: A amostra foi composta de pacientes dermatológicos encaminhados para avaliação oftalmológica, nos anos de 2016 e de 2017. Estudou-se a concomitância de doenças dermatológicas com as afecções oftalmológicas por meio da coleta simultânea do histórico dermatológico (prontuários registrados com dados gerais e diagnóstico) e de dados da consulta oftalmológica após o encaminhamento. Resultados: Foram avaliados pela oftalmologia 224 pacientes, sendo 65% do sexo feminino, 80% caucasianos, com idade variando entre 1 mês e 85 anos. As situações cujo encaminhamento foi mais prevalente foram psoríase, lúpus, vitiligo e rosácea (18,3%, 13,8%, 12,9% e 10,7%, respectivamente). Fototerapia crônica e uso de hidroxicloroquina representaram 35,7% e 22,3% dos pacientes. Casos de neurofibromatose, micose fungoide, líquen plano, neoplasias de pele, atopias, pênfigo e esclerodermia também estiveram presentes. Cegueira legal foi detectada em 6%, e deficiências visuais ligadas a afecções dermatológicas foram verificadas em 16,5% dos casos. As alterações oculares mais prevalentes foram catarata (18,9%), blefarite (15,9%), pterígio (5,3%) e conjuntivite (5,3%). Conclusão: Encontrou-se elevada frequência de alterações oftalmológicas em uma população de pacientes com doenças dermatológicas. Assim, o estudo e a análise de manifestações oculares em pacientes dermatológicos podem auxiliar na detecção precoce e na prevenção de complicações.

ABSTRACT Objective: To analyze the clinical profile of patients under dermatological care and referred to ophthalmological evaluation. Methods: The sample comprised dermatology patients referred to ophthalmological evaluation in 2016 and 2017. The simultaneous occurrence of skin and ophthalmic diseases was studied, by collecting dermatological history (medical records containing general data and diagnosis) and ophthalmic consultation data following referral. Results: A total of 224 patients were assessed, 65% were female, 80% were white, and age varied between one month and 85 years. The conditions more often referred were psoriasis, lupus, vitiligo and rosacea (18.3%, 13.8%, 12.9% and 10.7%, respectively). Chronic phototherapy and use of hydroxychloroquine were observed in 35.7% and 22.3% of patients, respectively. Cases of neurofibromatosis, mycosis fungoides, lichen planus, skin cancer, atopic dermatitis, pemphigus and scleroderma were also reported. Legal blindness was detected in 6% and visual impairment related to skin conditions in 16.5% of patients. The most prevalent ocular changes were cataracts (18.9%), blepharitis (15.9%), pterygium (5.3%) and conjunctivitis (5.3%). Conclusion: A high frequency of ophthalmic changes in a population of dermatological patients was found. In this context, studying and analyzing ocular manifestations in dermatological patients could be useful in early detection and prevention of complications.

Vision status, ophthalmic assessment, and quality of life in the very old / Visão, avaliação oftalmológica e qualidade de vida em longevos

ABSTRACT Purpose: To determine the vision status, ophthalmic findings, and quality of life among the very elderly. Methods: This was a cross-sectional observational study of individuals aged 80 years and above. A comprehensive ophthalmic exam was performed with mea surement of both the presenting (PVA) and best-corrected visual acuity. The Quality of Life Short Form-36 (SF-36) and the Visual Function Questionnaire (VFQ-25) were also administered. Results: A total of 150 non-institutionalized participants were assigned to three age groups: 80-89 years (n=70), 90-99 years (n=50), and 100 years and older (n=30). PVA and best-corrected visual acuity were normal (≥20/30) in 20 (13.3%) and 37 participants (24.7%), respectively. Regarding PVA, mild visual impairment (<20/30 to ≥20/60) was found in in 53 (35.4%), moderate visual impairment (<20/60 to ≥20/200) in 50 (33.3%), severe visual impairment (<20/200 to ≥20/400) in 8 (5.3%), and blindness (<20/400) in 19 (12.7%) participants. Regarding best-corrected visual acuity, mild, moderate, and severe visual impairments were present in 55 (36.7%), 38 (25.3%), and 5 (3.3%) participants, respectively, and blindness was present in 15 (10%). The main causes of visual impairment/blindness were cataract (43.8%), refractive errors (21.5%), age-related macular degeneration (17.7%), and myopic degeneration (3.8%). SF-36 scores were worse in those with low visual acuity, while VFQ-25 domain scores were poorer in those with vision impairment/blindness. Conclusion: Vision impairment and blindness was present in three-quarters of this sample, but it was notable that adequate correction with spectacles improved visual acuity. This reinforces the need for regular ophthalmic care in elderly patients to improve their quality of life by optimizing vision.

RESUMO Objetivos: Determinar a visão, achados oftalmológicos e qualidade de vida em longevos. Métodos: Estudo observacional transversal em indivíduos com idade entre 80 anos ou mais. Realizado exame oftalmológico com medida da acuidade visual apresentada e da acuidade visual melhor corrigida. Foram administrados os questionários: Qualidade de Vida Forma Curta - 36 (SF-36) e Qualidade de Função Visual (VFQ-25). Resultados: Total de 150 indivíduos não-institucionalizados foram estudados, divididos em três faixas etárias: 80 a 89 anos (n=70); 90 a 99 anos (n=50) e 100 anos ou mais (n=30). Acuidade visual apresentada normal (≥20/30) foi encontrada em 20 (13,3%) participantes; deficiência visual leve (<20/30 a ≥20/60), em 53 (35,4%); deficiência visual moderada (< 20/60 a ≥20/200) em 50 (33,3%); deficiência visual grave (<20/200 para ≥20/400) em 8 (5,3%) e cegueira (<20/400) em 19 (12,7%). A acuidade visual com a melhor correção aumentou para 37 (24,7%) indivíduos normais; deficiência leve aumentou para 55 (36,7%); deficiência visual moderada diminuiu para 38 (25,3%); deficiência visual grave foi reduzida para 5 (3,3%) e cegueira foi reduzida para 15 (10%). As principais causas de deficiência visual/cegueira foram: catarata (43,8%) erro refrativo (21,5%), degeneração macular relacionada à idade (17,7%), e degeneração miópica (3,8%). A pontuação no Questionário de Qualidade de Vida foi pior naqueles com baixa visão para perto. No questionário VFQ -25 os domínios com menor pontuação ocorreram nos indivíduos com baixa visão/cegueira. Conclusão: Deficiência visual/cegueira mostrou-se presente em três quartos desta amostra de longevos. A prescrição de óculos adequados proporcionou melhora da acuidade visual, reforçando a necessidade de atendimento oftalmológico regular desses pacientes para assegurar a qualidade de vida e de visão.

Sinais e sintomas em hipertensão arterial / Signs and symptoms of hypertension

A hipertensão arterial humana primária ou essencial abrange, na sua maioria, indivíduos no estágio I (pressão arterial sistólica [PAS] entre 140 e 160mmHg e pressão arterial diastólica [PAD] entre 90 e 100mmHg) e mesmo em estágios mais avançados (estágio II - PAS até 180mmHg, PAD até 110mmHg). Assintomática por muitos anos, tem sido cunhada como "o matador silencioso". Os sintomas e sinais mais frequentemente observados nos indivíduos hipertensos estão associados à hipertensão arterial de origem secundária ou são consequência da duração e gravidade do comprometimento dos órgãos-alvo (coração, cérebro, rim, olhos e vasos arteriais)...

The primary human arterial hypertension or essential cover mostly individuals in stage I (systolic blood pressure [SBP] between 140 and 160mmHg and diastolic blood pressure [DBP] between 90 and 100mmHg) and even in the most advanced stages (stage II - PAS until 180mmHg, PAD until 110mmHg). Asymptomatic for many years, it has been named as "the silent killer". The symptoms and signals more frequently observed in hypertensive individuals are related to arterial hypertension that has secondary orign or being consequence due duration and gravity of target organ which were affected (heart, brain, kidney, eyes and anterial vessels)...

Enfermedades oculares asociadas y factores de riesgo en ancianos con degeneración macular relativa a la edad / Associated ocular diseases and risk factors in old people with age-related macular degeneration

Introducción: La degeneración macular relativa a la edad es causa principal de invalidez en personas mayores de 60 años en todo el mundo. Método: Se realizó una investigación descriptiva y transversal, en el área de salud Héroes de Girón del Cerro, cuyo universo estuvo constituido por 651 ancianos con trastornos visuales no resueltos con corrección óptica y una muestra de 230 pacientes con degeneración macular relativa a la edad, después de aplicados los criterios de inclusión (aceptación voluntaria de participar en el estudio) y exclusión (ausencia de enfermedades psiquiátricas u orgánicas que le impidieran participar adecuadamente). Se analizaron las variables edad, sexo, color de la piel, antecedentes patológicos personales y familiares, sistémicos y oculares y factores de riesgo. Resultados: Predominaron los pacientes entre 70 y 79 años (72,61 por ciento), las mujeres (66,09 por ciento), de piel blanca (66,09 por ciento). Entre los antecedentes patológicos sistémicos y oculares personales y familiares, las enfermedades de origen vascular o con componente vascular importante fueron las más representadas. Entre los factores de riesgo, predominaron las enfermedades cardiovasculares (85,21 por ciento), posiblemente influidas por el resto de ellos (tabaquismo, sedentarismo y dieta inadecuada). La herencia estuvo presente en el 31,30 por ciento de los pacientes. Conclusiones: Lo más representativo en la serie analizada resulta la interacción del factor vascular con otras condiciones que pueden generar, agravar y potenciar los efectos de la isquemia tisular, además de la herencia y la edad en el complejo sistema de los factores de riesgo asociados a la enfermedad.

Introduction: The age-related macular degeneration is a leading cause of disability in people older than 60 years around the world. Method: A descriptive and traverse investigation, in the health area Héroes de Girón of Cerro municipality was carried out during the year 2007, whose universe was constituted by 651 old people with visual dysfunctions not resolved with optic correction and a sample of 230 patients with age-related macular degeneration, after having applied the inclusion approaches (voluntary acceptance of participating in the study) and exclusion (absence of psychiatric or organic disease that prevented him to participate appropriately). The variable age, sex, color of the skin, personal and family, systemic and ocular pathological antecedents and risk factors were analyzed. Results: prevailed the patients between 70 and 79 years (72.61 percent), women (66.09 percent), white skin (66,09 percent). Between the systemic and oculars, personal and family pathological antecedents, the vascular disease or with important vascular component were the most represented. Among the risk factors, cardiovascular diseases prevailed (85.21 percent), possibly influenced by the rest of them (smoking habit, sedentary life and inadequate diet). Heritage was present in 31.30 percent of patients. Conclusions:the most representative thing in the analyzed series is the interaction of the vascular factor with other conditions that can generate, to aggravate and to strengthen the effects of the tissular ischemia, besides the heritage and age in the complex system of the risk factors associated to the disease.

Causes of visual loss and their risk factors: an incidence summary from the Barbados Eye Studies / Causas de la pérdida visual y sus factores de riesgo: resumen de la incidencia a partir de los Estudios de Oftalmología de Barbados

Objectives: To summarize incidence and risk factors for each main cause of visual loss in an African-Caribbean population and discuss the implications of these data from a public health perspective. Methods: A nationally representative cohort (n = 4 709; ages 40-84 years at baseline) had ophthalmic and other examinations over 9 years. Incidence rates were estimated by the product-limit approach. Risk factors were evaluated from Cox regression models. Results: Average incidence was ~ 0.1 percent per year for blindness (< 6/120) and 0.7 percent per year for low vision (< 6/18 to 6/120), increasing steeply with age (P < 0.05) and affecting related quality of life (P < 0.05). Age-related cataract and open-angle glaucoma (OAG) accounted for 73.2 percent of blindness and diabetic retinopathy (DR) for 8.9 percent; cataract caused two-thirds of low vision. Average incidence was 5.1 percent per year for all lens changes (gradable/ungradable opacities or aphakia) and 0.4 percent per year for cataract surgery. Incidence of definite OAG was 0.5 percent per year (0.9 percent for suspect or probable); 53 percent of the affected were unaware. Persons with diabetes mellitus (DM) had a DR incidence of 4.4 percent per year. Age-related macular degeneration was rare (0.08 percent per year). Main cataract risk factors were age and DM. OAG incidence increased with age, intraocular pressure, family history, low ocular perfusion pressures, and thinner corneas. DR risk increased with early DM onset, DM duration, oral/insulin treatment, increased systolic and diastolic blood pressures, and hyperglycemia. Antihypertensive treatment halved DR risk. Conclusions: Incidence of visual impairment was high and significantly affected quality of life. Age-related cataract and OAG caused ~ 75 percent of blindness, indicating the need for public health action to increase appropriate cataract surgery and early OAG detection and treatment. Controlling DM and hypertension would help prevent...

Objetivo: Presentar un resumen de la incidencia y los factores de riesgo de cada causa principal de pérdida de la visión en una población afrocaribeña y examinar las implicaciones de estos datos desde una perspectiva de salud pública. Métodos: En una cohorte representativa al nivel nacional (n = 4 709; edades de 40 a 84 años al inicio) se hicieron exploraciones oftálmicas y de otros tipos durante nueve años. Se calcularon las tasas de incidencia mediante el método del producto-límite. Los factores de riesgo se evaluaron mediante modelos de regresión de Cox. Resultados: La incidencia promedio fue ~ 0,1 por ciento al año para la ceguera (< 6/120) y de 0,7 por ciento al año para la visión deficiente (< 6/18 a 6/120), que aumentó de manera pronunciada con la edad (P < 0,05) y afectó a la calidad de vida relacionada (P < 0,05). Las cataratas y el glaucoma de ángulo abierto relacionados con la edad representaron 73,2 por ciento de los casos de ceguera, y 8,9 por ciento de los casos de retinopatía diabética; las cataratas causaron dos tercios de los casos de visión deficiente. La incidencia media fue de 5,1 por ciento al año en todos los cambios del cristalino (opacidades graduables o no graduables o afaquia), y de 0,4 por ciento al año en la cirugía de cataratas. La incidencia del glaucoma de ángulo abierto definitivo fue de 0,5 por ciento al año (0,9 por ciento en el caso de la sospecha o la probabilidad); 53 por ciento de los pacientes afectados no era conciente. Las personas que padecían diabetes tenían una incidencia de retinopatía diabética de 4,4 por ciento al año. La degeneración macular relacionada con la edad fue muy infrecuente (0,08 por ciento al año). Los principales factores de riesgo de las cataratas fueron la edad y la diabetes. La incidencia de glaucoma de ángulo abierto aumentó con la edad, la presión intraocular, los antecedentes familiares, las presiones bajas de perfusión ocular y el grosor más fino de la córnea. El riesgo de retinopatía...

Non-functioning pituitary adenomas: clinical feature, laboratorial and imaging assessment, therapeutic management and outcome / Adenomas hipofisários não-secretores: avaliações clínica, laboratorial, neuro-radiológica e evolução após tratamento

OBJECTIVE: This study is an updated review of a Southeast Brazilian experience NFPA, emphasizing clinical features, laboratorial and imaging assessment, therapeutic management and outcome. DESIGN AND METHODS: Retrospective study, in which 104 patients with NFPA were evaluated by the same team of endocrinologists and neurosurgeon. Patients underwent biochemical evaluation, radiological studies and visual field assessment. RESULTS: Hypopituitarism and neuro-ophthalmological defects were observed in 89 percent. We observed GH deficiency (81.4 percent), hypogonadism (63.3 percent), adrenal hypofunction (59.5 percent), hypothyroidism (20.4 percent), high (38.5 percent) and low (16.7 percent) prolactin levels. Preoperative imaging classified 93 percent of the tumors as macroadenomas. Extra-sellar expansion was observed in 83.8 percent. Varying degrees of visual disturbance were observed in 74 percent. Primary treatment was transsphenoidal surgery (75 percent). Clinical control was achieved with one surgery in 37.5 percent of patients. The majority of patients needed a second therapeutic approach, radiotherapy or other surgeries. Immunohistochemistry resulted negative for pituitary hormones in 43 percent. Improvement of neuro-ophthalmological symptoms was observed in 61 percent of the patients after treatment. CONCLUSIONS: Our data confirm elevated prevalence of mass effect and hypopituitarism in patients harboring NFPA. Recurrence due to invasion or incomplete resection of the tumor is quite common, which frequently leads to a second therapeutic option.

OBJETIVOS: Esse estudo é uma revisão atualizada em adenomas hipofisários não-secretores (AHNS), enfatizando características clínicas, avaliações laboratorial e neuro-radiológica, manejo terapêutico e desfecho. MÉTODOS: Estudo retrospectivo, em que 104 pacientes com AHNS foram avaliados pela mesma equipe de endocrinologistas e neurocirurgião. Os pacientes foram submetidos à avaliação bioquímica, a estudos radiológicos e à avaliação de campo visual. RESULTADOS: Hipopituitarismo e distúrbios neuro-oftalmológicos foram observados em 89 por cento. Observou-se deficiência de GH (81,4 por cento), hipogonadismo (63,3 por cento), hipofunção adrenal (59,5 por cento), hipotireoidismo (20,4 por cento), concentrações elevadas (38,5 por cento) e baixas (16,7 por cento) de prolactina. Imagens pré-operatórias classificaram os tumores em sua maioria como macroadenomas (93 por cento). Expansão extra-selar foi observada em 83,8 por cento. Graus variados de distúrbios visuais foram observados em 74 por cento. O tratamento de escolha foi a cirurgia transesfenoidal (75 por cento). O controle clínico foi alcançado com cirurgia em 37,5 por cento dos pacientes. A maioria dos pacientes precisou de segunda abordagem terapêutica, radioterapia ou outras cirurgias. A imunoistoquímica resultou negativa para hormônios hipofisários em 43 por cento. Melhora de sintomas neuro-oftalmológicos foi observada em 61 por cento dos pacientes após o tratamento. CONCLISÕES: Os dados do estudo confirmam elevada prevalência de efeitos de massa e hipopituitarismo em pacientes com AHNS. Recorrência causada por invasão ou ressecção incompleta do tumor é comum, levando frequentemente à segunda opção terapêutica.

Factors leading to the computer vision syndrome: an issue at the contemporary workplace

INTRODUCTION: Vision and eye related problems are common among computer users, and have been collectively called the Computer Vision Syndrome (CVS). METHODS: An observational study in order to identify the risk factors leading to the CVS was done. Twenty-eight participants answered a validated questionnaire, and had their workstations examined. The questionnaire evaluated personal, environmental, ergonomic factors, and physiologic response of computer users. The distance from the eye to the computers' monitor (A), the computers' monitor height (B), and visual axis height (C) were measured. The difference between B and C was calculated and labeled as D. Angles of gaze to the computer monitor were calculated using the formula: angle=tan-1(D/A). Angles were divided into two groups: participants with angles of gaze ranging from 0 degree to 13.9 degrees were included in Group 1; and participants gazing at angles larger than 14 degrees were included in Group 2. Statistical analysis of the evaluated variables was made. RESULTS: Computer users in both groups used more tear supplements (as part of the syndrome) than expected. This association was statistically significant (p < 0.10). Participants in Group 1 reported more pain than participants in Group 2. Associations between the CVS and other personal or ergonomic variables were not statistically significant. CONCLUSIONS: Our findings show that the most important factor leading to the syndrome is the angle of gaze at the computer monitor. Pain in computer users is diminished when gazing downwards at angles of 14 degrees or more. The CVS remains an under estimated and poorly understood issue at the workplace. The general public, health professionals, the government, and private industries need to be educated about the CVS.

Riesgos y daños a la salud derivados del uso de videoterminal / Health hazards associated with the use of video display terminals

OBJETIVO: Evaluar la relación de daños a la salud con el uso de videoterminal, riesgos laborales y factores psicosociales en trabajadores de un diario informativo. MATERIAL Y MÉTODOS: En 1998 se estudió una muestra representativa (n=68) de una población de 218 trabajadores de un diario informativo de la Ciudad de México. Se presentan los resultados obtenidos a partir de una encuesta de autoaplicación, los cuales fueron comparados posteriormente con datos de exámenes clínicos. La hipótesis de esta investigación sustenta que, tanto el uso actual como la exposición acumulada de videoterminal, se asocian con mayor riesgo de presentar padecimientos visuales, músculo-esqueléticos y dermatológicos; trastornos mentales y psicosomáticos, y fatiga general. Los resultados fueron analizados en función de diferentes riesgos laborales: (riesgo visual, trabajo sedentario, uso de mouse, riesgo postural, calor excesivo y hacinamiento) y factores psicosociales derivados de la organización del trabajo (demandas psicológicas, control sobre el trabajo y apoyo social). Para valorar su relación con los daños derivados del uso de videoterminal, se estimaron razones de prevalencias ajustadas por confusores potenciales (edad, sexo y escolaridad). RESULTADOS: Las mujeres presentaron prevalencias más elevadas de trastornos músculo-esqueléticos en la mayoría de los daños investigados, y las diferencias fueron significativas entre ambos sexos para dermatitis y eczema seborreico. El uso de videoterminal se asoció con mayor riesgo de fatiga neurovisual, trastornos músculo-esqueléticos en manos y extremidades superiores, dermatitis y eczema seborreico. De los riesgos laborales, los más asociados con trastornos fueron el uso de mouse y el riesgo postural. Los factores psicosociales se relacionaron principalmente con los padecimientos de naturaleza psicológica (trastornos mentales, psicosomáticos y fatiga general). CONCLUSIONES: Con el uso intensivo de videoterminal los padecimientos investigados son frecuentes, en especial, los trastornos músculo-esqueléticos en manos. Además, el enriquecimiento de las tareas y el propio control del proceso laboral tuvieron efecto protector contra los trastornos psicosomáticos y la fatiga patológica
