A Descriptive Study of Chronic Obstructive Pulmonary Disease in Tertiary Care Clinics of a Caribbean Island / Estudio descriptivo de la enfermedad pulmonar obstructiva crónica en clínicas de atención terciaria de una isla caribeña

ABSTRACT Objective: To determine the relationship between severity of chronic obstructive pulmonary disease (COPD) and quality of life as well as COPD's correlation with depressive symptoms in West Indian subjects. Methods: This is a cross-sectional, observational study of outpatients with COPD in tertiary care. The severity of COPD was determined by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage, GOLD group, and body mass index, airflow obstruction, dyspnoea and exercise capacity (BODE) index. Quality of life was assessed by the St George Respiratory Questionnaire (SGRQ) and COPD Assessment Test (CAT), and depression was assessed by the Center for Epidemiologic Studies Depression Scale (CES-D). Results: A total of 105 patients (85.7% male, 37.1% Indo-Trinidadian, 42.9% Afro-Trinidadian, 64.8% primary level education) were recruited with a mean age of 66.9 years (standard deviation: 9.60 years). The median body mass index was 25 kg/m2; 26.7% were underweight. Risk factors identified were: ever-smokers (27.6%), marijuana (20%), biomass (81.9%), passive smoke (70.5%), occupational exposures (80%). The CES-D of 25% of the patients was ≥16. Co-morbidities included diabetes (22%), hypertension (29%), gastro-oesophageal reflux disease (10%) and previous myocardial infarction (15%). A total of 59% of the patients reported a monthly household income of less than US$800. Lower level of education was associated with worse SGRQ (total and impact), lower forced expiratory volume in one second, modified Medical Research Council scale (mMRC) of ≥ 2 and higher BODE index. Higher GOLD group correlated with worse SGRQ, CAT and CES-D. Higher CES-D was associated with shorter six-minute walk distance, worse SGRQ, CAT and mMRC scores, higher GOLD group and increased COPD admissions per year. Patients with a CES-D of ≥ 16 walked shorter distances. Higher BODE quartile was associated with worse SGRQ, CAT and CES-D scores. Conclusion: Higher GOLD group and higher BODE quartile were associated with worse quality of life scores and higher depression scores. Patients in higher GOLD groups should be screened for depression. Education on COPD should be targeted at those of lower socioeconomic status.

RESUMEN Objetivo: Determinar la relación entre la severidad de la enfermedad pulmonar obstructiva crónica (EPOC) y la calidad de vida, así como la correlación de la EPOC con síntomas depresivos en sujetos antillanos. Métodos: Se realizó un estudio observacional transversal de pacientes ambulatorios con EPOC en cuidados terciarios. La severidad de la EPOC fue determinada por la etapa de la Iniciativa Global para la Enfermedad Pulmonar Obstructiva Crónica (GOLD, en inglés), el grupo GOLD, así como el índice de masa corporal, la obstrucción del flujo de aire, la disnea y la capacidad de ejercicio (índice BODE). La calidad de vida fue evaluada mediante el Cuestionario Respiratorio de Saint George (CRSG) y la prueba de evaluación de la EPOC (CAT, en inglés), en tanto que la depresión fue evaluada por la Escala de Depresión del Centro de Estudios Epidemiológicos (CES-D). Resultados: Un total de 105 pacientes (85.7% varones, 37.1% indotrinitenses, 42.9% afrotrinitenses, 64.8% nivel de educación primaria) fueron reclutados con una edad promedio de 66.9 años (desviación estándar: 9.60 años). El índice de masa corporal promedio fue de 25 kg/m2; 26.7% por debajo del peso normal. Los factores de riesgo identificados fueron: fumar ocasionalmente (27.6%), marihuana (20%), biomasa (81.9%), humo pasivo (70.5%), exposición ocupacional (80%). El CES-D del 25% de los pacientes fue ≥ 16. Las comorbilidades incluyeron diabetes (22%), hipertensión (29%), enfermedad por reflujo gastroesofágico (10%), y previo infarto del miocardio (15%). Un total de 59% de los pacientes reportaron un ingreso mensual familiar de menos de $800 USD. El nivel más bajo de educación se asoció con un peor (CRSG) (total e impacto), menor volumen espiratorio forzado en un segundo, Escala del Consejo de Investigaciones Médicas modificada (mMRC) de ≥ 2, y más alto índice de BODE. Un grupo más alto de GOLD se correlacionó con peores resultados de CRSG, CAT y CES-D. El CES-D más alto se asoció con una caminata de una distancia más corta en seis minutos, peores puntuaciones de CRSG, CAT y mMRC, un grupo más alto de GOLD, y mayores ingresos de EPOC por año. Los pacientes con CES-D de ≥ 16 caminaron distancias más cortas. El cuartil más alto de BODE estuvo asociado con las puntuaciones peores de CRSG, CAT y CES-D. Conclusión: El grupo GOLD más alto y el cuartil más alto de BODE se asociaron con peores puntuaciones de calidad de vida y puntuaciones de depresión más altas. Los pacientes en los grupos de GOLD más altos deben ser tamizados para detectar si padecen depresión. La educación sobre la EPOC debe estar dirigida a aquellos que tienen una situación socioeconómica inferior.

Vitamin D deficiency in risk groups living in tropical curaçao / Deficiencia de vitamina D en los grupos de riesgo de curazao tropical

OBJECTIVE: Curaçao (12 degrees 10N, 69 degrees 0W) is characterized by whole year abundant sunshine (8-10 hours/day). We challenged the automatic assumption that people living in tropical countries do not have a high risk of vitamin D deficiency, and investigated the vitamin D status in a tropical environment. METHODS: For this, we selected fiftytwo elderly people with little or no exposure to direct sunlight [median 84 (60-96) years; 34 females, 18 males] and who were cared for by community nurses or lived in retirement or nursing homes. Furthermore, six rehabilitating orthopaedic patients [median 72 (38-90) years; one female, five males] were included. Serum 25(OH)D, calcium, phosphate, parathyroid hormone (PTH) and creatinine were measured. Those exhibiting elevated creatinine, PTH or both had their 1,25dihydroxyvitamin D [1,25(OH)2D] examined. RESULTS: Serum levels of 25(OH)D below 25, 50 and 75 nmol/L were detected in, respectively, seven (12%), 22 (38%) and 48 (83%) of the fiftyeight persons. Four persons had combined high creatinine and PTH, and low 1,25(OH)2D, which was not known by their caregivers. CONCLUSION: Abundant sunshine outdoors is no guarantee for vitamin D sufficiency. More attention is needed for vitamin D deficiency in risk groups living in tropical areas and elderly persons with poor kidney function.

OBJETIVO: Curazao (12 grados 10N, 69 grados 0W) se caracteriza por su abundante luz solar durante todo el año (8-10 horas/día). Ponemos en duda la suposición automática de que los habitantes de países tropicales no poseen un alto riesgo de deficiencia de vitamina D, e investigamos los niveles de vitamina D en un ambiente tropical. MÉTODOS: Para ello, seleccionamos a cincuenta y dos personas de avanzada edad [mediana 84 (60-96) años; 34 mujeres, 18 hombres] con poca o ninguna exposición directa a la luz solar, cuidados por enfermeras comunitarias o que vivían en hogares de ancianos o casas de retiro. Además, se incluyeron seis pacientes bajo rehabilitación ortopédica [mediana 72 (38-90) años; una mujer, cinco hombres]. Se les realizaron las siguientes mediciones: 25(OH)D en suero, calcio, fosfato, hormona paratiroidea (HPT), y creatinina. A todos aquellos que mostraron niveles elevados de creatinina, de HPT, o de ambas, se les realizó un examen de 1,25dihidroxivitamina D [1,25(OH)2D]. RESULTADOS: Se detectaron niveles séricos de 25(OH)D por debajo de 25, 50 y 75 nmol/L en siete (12%), 22 (38%) y 48 (83%) de las cincuenta y ocho personas, respectivamente. Cuatro personas presentaron una combinación de elevada creatinina y HPT, y bajo 1,25(OH)2D, datos desconocidos para sus cuidadores. CONCLUSIÓN: La abundancia de luz solar exterior no es garantía de suficiencia de vitamina D. Se necesita prestar mayor atención a la deficiencia de vitamina D en los grupos de riesgo que viven en áreas tropicales, así como a las personas de edad avanzada con pobre función renal.

Child abuse: a common problem in Curaçao? / Abuso infantil: ¿Un problema común en Curazao?

OBJECTIVE: To assess the prevalence of child abuse among high school students in Curaçao. METHODS: A questionnaire survey among high school students up to 17 years of age was conducted. The questionnaire was based on existing literature and validated questionnaires. The questionnaire used was analysed and adapted to the situation in Curaçao by a panel of experts on child abuse. The primary objective was to gain insight into the incidence, prevalence and various forms of child abuse among students in Curaçao. Five forms of child abuse are distinguished in the literature: physical abuse, emotional abuse, sexual abuse, neglect and exploitation. Furthermore, the degree of confidence of the students in general practitioners (GPs) as care providers in the field of child abuse was explored. RESULTS: Questionnaires from 545 of the 628 respondents were included. In total, 43% of the respondents had ever-experienced an event which could be defined as (a form of) child abuse. More than one-third of the respondents reporting child abuse ever had an experience that could be interpreted as physical abuse. More than 15% of the respondents reporting child abuse had experienced sexual abuse. Girls experienced significantly more sexual abuse than boys. Emotional abuse in the last year was experienced by 3% of the respondents. One per cent of the respondents ever-experienced neglect. according to most respondents, GPs were not seen as care providers in cases of child abuse; they believed that GPs were mainly to be consulted for illnesses or physical symptoms and not for forms of child abuse. CONCLUSION: The prevalence of ever-having-experienced a form of child abuse is estimated at 431 per 1000 students. Child abuse, particularly physical abuse, is common in Curaçao, and is probably comparable to other surrounding countries. General practitioners were not seen as care providers in identifying and reporting cases of child abuse according to most respondents.

OBJETIVO: Evaluar la prevalencia del abuso infantil entre estudiantes de secundaria en Curazao. MÉTODOS: Se aplicó un cuestionario entre estudiantes de secundaria de hasta 17 años de edad. El cuestionario se basó en la literatura existente y cuestionarios validados. El cuestionario usado fue analizado y adaptado a la situación de Curazao por un panel de expertos en abuso infantil. El objetivo principal fue profundizar los conocimientos acerca de la incidencia, prevalencia y diversas formas de abuso infantil entre estudiantes en Curazao. La literatura distingue cinco formas de abuso infantil: abuso físico, abuso emocional, abuso sexual, negligencia y explotación. Además, se exploró el grado de confianza de los estudiantes en los médicos generales (MGs) como proveedores de cuidado en el área del abuso infantil. RESULTADOS: Se incluyeron los cuestionarios de 545 de los 628 encuestados. En total, 43% de los encuestados nunca habían pasado por una experiencia que pudiera interpretarse como (forma de) abuso infantil. Más de un tercio de los encuestados a los que se les pidió reportar abuso infantil, jamás había tenido una experiencia que pudira interpretarse como abuso físico. Más del 15% de los encuestados sobre abuso infantil habían experimentado abuso sexual. Las niñas experimentaron significativamente más abuso sexual que los niños. El abuso emocional en el último año fue experimentado por 3% de los encuestados. El uno por ciento de los encuestados jamás experimentó negligencia. Los médicos generales no eran vistos como proveedores de cuidado en los casos de abuso infantil, de acuerdo con la mayoría de los encuestados. Según ellos, los MGs deben ser consultados principalmente en el caso de enfermedades o síntomas físicos, y no en casos de formas de abuso infantil. CONCLUSIÓN: La prevalencia de nunca haber experimentado una forma de maltrato infantil se estima en 431 por 1000 estudiantes. El abuso infantil, en particular el abuso físico, es común en Curazao, y es probablemente comparable a otros países circundantes. Los médicos generales no eran vistos como proveedores de cuidado en cuanto a identificar y reportar casos de abuso infantil, según la mayor parte de los encuestados.

Optimizing chronic HIV care in the Dutch Caribbean: a questionnaire based study on experience and perception of healthcare workers / Optimización del cuidado del VIH crónico en el Caribe Holandés: un estudio basado en un cuestionario sobre la experiencia y la percepción de los trabajadores de la salud

OBJECTIVE: Human immunodeficiency virus (HIV) infection has become a chronic disorder for which adaptation of current healthcare practices is needed. In Curaçao, a new organization of chronic HIV care is being set up based on task shifting in which healthcare workers (HCWs) will deliver HIV care more prominently within the primary healthcare system. In preparation for implementation of the proposed task-shifting model, we investigated the perception of HCWs regarding existing HIV care in Curaçao and the need for training in HIV/AIDS among HCWs. SUBJECTS AND METHODS: An in-depth questionnaire based study was used. Nineteen HCWs of seven different cadres were interviewed. The questionnaire constituted four sections: quality of existing HIV care, respondents own knowledge and willingness to be trained, need for training in HIV/AIDS and preferred educational approaches. RESULTS: Quality of existing HIV services in Curaçao is considered acceptable but needs improvement mainly to facilitate integration of chronic HIV care. All respondents indicated that training in HIV/AIDS is needed among HCWs in Curaçao, especially for nurses and general practitioners. All were willing to participate in training with varying amounts of time to be spent. Training should be tailored to the level of expertise of HCWs and to the role a HCW is expected to have in the new healthcare delivery framework. CONCLUSION: There is need for training to ensure the effective integration of chronic HIV care into the existing healthcare delivery system in Curaçao. There is a willingness and need in all cadres for training with e-learning as a preferred educational tool.

OBJETIVO: La infección por virus de inmunodeficiencia humana (VIH) se ha estado convirtiendo en un trastorno crónico que requiere la adaptación de las prácticas actuales de salud. En Curazao, se ha estado creando una nueva organización de la atención del VIH crónico, basada en un cambio de tareas en las que los trabajadores de la salud (TS) brindarán un cuidado prominente al VIH dentro del sistema primario de atención a la salud. En preparación para la implementación del modelo de cambio de tareas propuesto, investigamos la percepción de los TS en relación con la atención actual al VIH en Curazao y la necesidad de capacitación en torno al VIH/SIDA entre los TS. SUJETOS Y MÉTODOS: Se utilizó un estudio basado en un cuestionario detallado. Se entrevistaron diecinueve TS de siete cuadros diferentes. El cuestionario estaba constituido por cuatro secciones: calidad del cuidado existente al VIH, conocimiento y voluntad de los propios encuestados para recibir capacitación en la atención al VIH/SIDA, y los enfoques educativos preferidos. RESULTADOS: Calidad de los servicios del VIH existentes en Curazao se considera aceptable pero necesita mejorar principalmente en cuanto a facilitar la integración de la atención del VIH crónico. Todos los encuestados indicaron que se necesita capacitación en VIH/SIDA entre los TS de Curazao, especialmente para las enfermeras y médicos generales. Todos estaban dispuestos a participar en el entrenamiento, siendo variable la cantidad de tiempo a emplear en el mismo. La capacitación se debe diseñar de acuerdo con el nivel de conocimientos de los TS, y el papel que se espera que un TS desempeñe en el nuevo marco de cuidados de la salud. CONCLUSIÓN: Hay necesidad de entrenamientos para integrar de manera efectiva la atención al VIH crónico al sistema actual de servicios de cuidados de la salud en Curazao. Todos los cuadros tienen la voluntad y la necesidad de recibir capacitación en esta área, para lo cual el aprendizaje electrónico es la herramienta educativa de preferencia.

A case study of the implementation of a competency-based curriculum in a Caribbean Teaching Hospital / Un estudio de caso de la implementación de un currículo basado en competencias en un Hospital Docente del Caribe

OBJECTIVE: Several teaching hospitals are currently modifying their curriculum to comply with the changing demands in medical education. As a result, we decided to evaluate whether a competency-based curriculum implemented in a Caribbean teaching hospital fulfilled the requirements as defined by the CanMEDS framework. METHODS: We made use of a triangulation method in the survey to obtain information on the educational process. Two separate methods were used consisting of site visits by visiting professors and a medical educator. The focus was on the structure, content and assessments of the educational activities. RESULTS: Major recommendations included increased involvement of medical specialists in the educational activities in the clinical workplace. There was need for improvement of communication between medical specialists, patients, nurses, trainees and residents. Overall, improvements were observed in the structure of clinical rotations and content of the training programme. CONCLUSION: The implemented assessment programme provided necessary information for effective evaluation of the competency-based curriculum. We were able to identify new and feasible methods for improving the curriculum in our educational setting.

OBJETIVO: Varios hospitales docentes están actualmente modificando sus currículos a fin de satisfacer las demandas cambiantes de la educación médica. Por tal motivo, se tomó la decisión de evaluar si un currículo basado en competencias puesto en marcha en un hospital docente del Caribe cumplía con los requerimientos definidos por el programa de formación médica conocido como CanMEDS Framework. MÉTODOS: Se hizo uso de un método de triangulación en el estudio, a fin de obtener información sobre el proceso educativo. Se usaron dos métodos separados consistentes en visitas de inspección realizadas por profesores visitantes y un educador médico. La atención se centró en la estructura, el contenido, y la evaluación de las actividades educativas. RESULTADOS: Las recomendaciones principales incluyeron la necesidad de aumentar la participación de médicos especialistas en el lugar donde los estudiantes realizan su trabajo clínico. Se vio la necesidad de mejorar la comunicación entre especialistas médicos, pacientes, enfermeras, entrenados, y residentes. En general, se observaron mejoras en la estructura de las rotaciones clínicas y el contenido de los programas de entrenamiento. CONCLUSIÓN: El estudio realizado proveyó la información necesaria para la evaluación efectiva del currículo basado en competencias, e hizo posible identificar métodos nuevos y factibles para mejorar los planes de estudio en nuestro contexto educacional.

Registration of work-related diseases, injuries, and complaints in Aruba, Bonaire, and Curaçao / Registro de enfermedades, lesiones y síntomas relacionados con el trabajo en Aruba, Bonaire y Curazao

OBJECTIVE: To estimate the incidence of work-related diseases, injuries, and complaints in Aruba, Bonaire, and Curaçao and to identify some next steps in the prevention process. METHODS: All of the three countries' 18 occupational health specialists were asked to participate; 100 percent agreed to report all work-related diseases, injuries, and complaints in 2004-2008. A standard online notification form was used to register cases in a database maintained by the Netherlands Center for Occupational Diseases (NCOD). The public health service of Curaçao analyzed the data and presented the results to the participating physicians during educational and feedback meetings. RESULTS: During the study period, 1 519 cases were reported: 720 (47.0 percent) work-related diseases; 515 (34.0 percent) injuries; and 284 (19.0 percent) complaints. The mean patient age was 42.4 years (range 16-70 years); 924 (60.8 percent) were males and 571 (37.6 percent), females. Most frequently reported were musculoskeletal diseases, injuries, and complaints; mental health disorders; and skin injuries. Analysis showed incidence rates of work-related diseases, injuries, and complaints in Aruba to be 157 new cases per 100 000 employee years; in Bonaire, 53/100 000; and in Curaçao, 437/100 000. CONCLUSIONS: These results suggest that labor protection laws need improvement and that preventive action should be fostered. Further study is needed on working conditions, preventive policy, and the quality of occupational health and safety practices in Aruba, Bonaire, and Curaçao. Funding is imperative for collecting and publishing accurate data, which will keep this problem on the social-political agenda.

OBJETIVO: Calcular la incidencia de enfermedades, lesiones y síntomas relacionados con el trabajo en Aruba, Bonaire y Curazao e identificar los pasos siguientes en el proceso de prevención. MÉTODOS: Se invitó a participar a los 18 especialistas en salud ocupacional de los tres países; todos aceptaron notificar todas las enfermedades, lesiones y síntomas relacionados con el trabajo entre el 2004 y el 2008. Se usó un formulario estándar de notificación en línea para registrar los casos en una base de datos mantenida por el Centro para las Enfermedades Ocupacionales de los Países Bajos. El servicio de salud pública de Curazao analizó los datos y presentó los resultados a los médicos participantes durante las reuniones educativas y de retroalimentación. RESULTADOS: Durante el período del estudio se notificaron 1 519 casos relacionados con el trabajo: 720 (47,0 por ciento) enfermedades, 515 (34,0 por ciento) lesiones y 284 (19,0 por ciento) síntomas. La edad promedio de los pacientes fue 42,4 años (recorrido, 16-70 años); 924 (60,8 por ciento) eran varones y 571 (37,6 por ciento), mujeres. Se notificaron con mayor frecuencia las enfermedades, lesiones y síntomas musculoesqueléticos; los trastornos mentales; y las lesiones cutáneas. El análisis mostró tasas de incidencia de enfermedades, lesiones y síntomas relacionados con el trabajo de 157 nuevos casos por 100 000 empleados por año en Aruba, 53/100 000 en Bonaire y 437/100 000 en Curazao. CONCLUSIONES: Estos resultados indican que las leyes de protección laboral deben mejorarse y que deben promoverse las medidas preventivas. Es necesario llevar a cabo otros estudios sobre las condiciones de trabajo, los planes de prevención y la calidad de la salud ocupacional y las prácticas de seguridad en Aruba, Bonaire y Curazao. Se requiere financiamiento para recopilar y publicar datos exactos, a fin de mantener este problema en la agenda política y social.

Epidemiology of febrile diseases in the emergency department of a Caribbean Island: the Curaçao experience / Epidemiología de las enfermedades febriles en el departamento de emergencias de una Isla Caribeña: la experiencia de Curazao

OBJECTIVE: The aetiology of febrile diseases in tropical countries often remains poorly characterized. We aim to describe the aetiology and outcome of febrile illnesses at the Emergency Department (ED) in Curaçao. METHODS: From April 2008 - April 2009, all adult febrile patients (T > 38.5°C) at the ED of the St Elisabeth Hospital, Curaçao, Netherlands Antilles, were included. Clinical data were recorded, routine laboratory measurements and blood cultures were taken. Final diagnoses were made at discharge by an independent physician and in retrospect by the main investigator. RESULTS: Four hundred and three patients were included: 223 patients (55.6%) were hospitalized, 32 patients (7.9%) died and 18 patients (4.5%) were admitted to the Intensive Care Unit. In 129 febrile patients (32.0%), infection was proven; 84.4% of patients had bacterial (29.0% urinary tract infection, 23.2% pneumonia infection), 5.6% viral and 10.0% parasitic or fungal infections. Twenty-one patients (5.2%) were discharged with a non-infectious diagnosis and 172 patients (42.7%) without a clear diagnosis. CONCLUSION: A high mortality rate of 7.9% was observed. We found a high prevalence of bacterial infections, with pneumonia and urinary tract infections as the most common causes of fever. One in 20 patients did not have an infectious disease.

OBJETIVO: La etiología de las enfermedades febriles en los países tropicales posee aún una pobre caracterización. El presente trabajo se propone describir la etiología y la evolución clínica de las enfermedades febriles en el Departamento de Emergencias (DE) de Curazao. MÉTODOS: De abril 2008 - abril 2009, todos los pacientes febriles adultos (T > 38.5°C) en el DE del Hospital Saint Elisabeth, de Curazao, Antillas Holandesas, fueron incluidos. Se registraron los datos clínicos, se tomaron las medidas de rutina de laboratorio y los cultivos de sangre. Los diagnósticos finales se hicieron a la hora del alta por un médico independiente y en retrospectiva por el investigador principal. RESULTADOS: Se incluyeron cuatrocientos tres pacientes: 223 pacientes (55.6%) fueron hospitalizados, 32 pacientes (7.9%) murieron, y 18 pacientes (4.5%) fueron ingresados en la Unidad de Cuidados Intensivos. En 129 pacientes febriles (32.0%) se comprobó la infección; 84.4% de los pacientes tenían infección bacteriana (29.0% infección de las vías urinarias, 23.2% infección por pneumonia), 5.6% viral y 10.0% infección parasitaria o fúngica. Veintiún pacientes (5.2%) fueron dados de alta con un diagnóstico no infeccioso, y 172 pacientes (42.7%) sin un diagnóstico claro. CONCLUSIÓN: Se observó una alta tasa de mortalidad de 7.9%. Se halló una alta prevalencia de infecciones bacterianas, siendo la pneumonía y las infecciones de las vías urinarias las causas más comunes de fiebre. Uno de cada 20 pacientes no tenía una enfermedad infecciosa.

Infra-inguinal arterial reconstruction for peripheral arterial disease: the Curaçao experience / Reconstrucción arterial infrainguinal en la enfermedad arterial periférica: la experiencia de Curazao

BACKGROUND: The prevalence and treatment of peripheral arterial disease in the Caribbean is not well documented. The aim of this study was to review the results from a small hospital in the Caribbean. METHODS: One-hundred and eight infra-inguinal arterial reconstructions on 90 patients were retrospectively reviewed Patients were classified according to the categories suggested by the Ad Hoc Committee on Reporting Standards of the Joint Councils of the Society for Vascular Surgery. Follow-up ranged from 0 to 103.1 months. The Kaplan-Meier method was used to visualize survival, limb salvage rates and primary and secondary patency rates. Cox regressions were used to identify potential risk factors. RESULTS: The limb salvage rates were 74.5% after one year and 71.4% after five years. Overall primary patency rates were 67.0 % after one year, 63.4% after three years and 50.8 % after five years. Overall secondary patency rates were 86.4% after one year and 75.1% after five years. The primary patency rate for autologous saphenous vein was 82.4% (SE 7.5%) after five years. The primary patency rates for prosthetic grafts were 62.1% (SE 8.5%) after one year; 56.9% (SE 9.2%) at three years and 37.9% (SE 16.7%) after five years. CONCLUSION: Infra-inguinal arterial bypass surgery is feasible in small Caribbean hospitals showing results comparable to major studies.

ANTECEDENTES: La prevalencia y el tratamiento de enfermedad arterial periférica en el Caribe no están bien documentados. El objetivo de este estudio fue examinar los resultados de un pequeño hospital en el Caribe. MÉTODOS: Se examinaron retrospectivamente ciento reconstrucciones arteriales infrainguinales en 90 pacientes. Los pacientes eran clasificados según las categorías sugeridas por el Comité Ad Hoc para el Reporte de Normas de los Consejos Unidos de la Sociedad de Cirugía Vascular. El seguimiento tuvo un rango de 0 a 103.1 meses. Se usó el método Kaplan-Meier con el objeto de ver las tasas de super-vivencia, salvamento de la extremidad, y tasas primarias y secundarias de permeabilidad. Se usaron regresiones de Cox para identificar los factores de riesgo potencial. RESULTADOS: Las tasas de salvamento de miembro fueron 74.5% después de un año y 71.4% después de cinco años. Las tasas generales de permeabilidad primaria fueron 67.0% después de un año, 63.4% después de tres años y 50.8% después de cinco años. Las tasas generales de permeabilidad secundaria fueron 86.4% después de un año y 75.1% después de cinco años. La tasa de permeabilidad primaria para la vena safena autóloga fue 82.4% (SE 7.5%) después de cinco años. Las tasas de permeabilidad primaria para los injertos prostéticos fueron 62.1% (SE 8.5%) después de un año, 56.9% (SE 9.2%) a los tres años y 37.9% (SE 16.7%) después de cinco años. CONCLUSIÓN: La cirugía de bypass arterial infrainguinal es factible en hospitales caribeños pequeños que muestran resultados comparables a los de estudios importantes.

Incidence of cervical carcinoma in a high-risk, non-screened area results of a retrospective analysis on the Dutch Caribbean Antilles from 1983 to 1998

Cancer of the uterine cervix is one of the most common malignancies worldwide. The average annual incidence of cervical cancer varies widely per geographical area. Some of the highest rates have been reported in Latin American and Caribbean countries. Previous research into the frequency of cervical carcinoma in Curaçao, the main island of the Dutch Caribbean, has reported predominantly far-advanced stages of the disease. The objectives of this study were to determine: whether there are indications of changes in the incidence of cervical carcinoma, whether these changes are a result of increased clinical attention paid by general practioners (GPs) and gynaecologists, and whether less advanced stages of cervical cancer were found, indicating earlier diagnosis. Data on patients with cervical carcinoma, obtained from records kept in the Department of Pathological Anatomy at the St Elisabeth Hospital in Curaçao were retrospectively analyzed for the period 1983 to 1998. To study the incidence rate over time, cumulative and incidence rates, standardized to the World Standard Population, were calculated and compared to the rates in other Latin American and Caribbean countries. The age-standardized incidence rate for Curaçao was 14.3 per 100 000 women. The cumulative rate up to 74-years-of-age was 1.6. Sub-division into the three groups showed a trend towards a decrease in the incidence and cumulative rates. A comparison of clinical staging International Federation of Obstetrics and Gynaecology (FIGO) showed a trend towards an increase in time of almost 48 to 59 in stage IA (ie less severe cases). A significant increase (p < 0.0001) was found in the numbers of smears performed in the complete period of 1983-1998, compared to a previously examined period of 1972-1982. The incidence of cervical cancer in Curaçao appears to be decreasing, and is lower than in other areas in the region. The number of smears GPs performed over time increased However the incidence is still relatively high compared to western countries and cases are still presenting in relatively advanced stages of the disease. Although the introduction of a screening programme might not influence the actual incidence of cervical cancer dramatically, nonetheless it may contribute to earlier diagnosis of cervical carcinoma

Curaçao patients with coronary artery disease have a higher prevalence of the HFE C282Y mutation

Epidemiological studies indicate a positive relation between iron status and coronary artery disease (CAD) risk The HFE C282Y allele is associated with increased iron status and higher CAD risk. We investigated whether HFE C282Ymight be a CAD risk factor in Curaçao in a case-control study design. The patient group comprised 42 men and 10 women. Fifty-four men and 30 women without history of CAD served as age and gender matched controls. HFE C282Y genotypes were established using sequence-specific priming polymerase chain reaction. None of the investigated subjects were homozygous for HFE C282Y, whereas 5/52 (9.6) CAD patients and 1/84 controls (1.2) were heterozygous for HFE C282Y (p = 0.03). The HFE C282Y mutation was 8.8 fold (95 CI 1.001, 77.8; p = 0.049) more prevalent in CAD patients than in controls. The HFE C282Y allele frequency in Curaçao is higher than that of African populations, but comparable with that of Jamaica. We conclude that Curaçao CAD patients have somewhat higher frequency of HFE C282Y heterozygosity than controls, and that the HFE C282Y allele frequency in the Curaçao population is higher than might be expected in persons of African descent. The consequences of HFE C282Y heterozygosity as CAD risk factor are as yet uncertain, since there is no proof that iron lowering reduces CAD risk

Surfactant treatment in premature infants with Respiratory Distress Syndrome in Curaçao

Surfactant replacement therapy for Respiratory Distress Syndrome (RDS) in premature neonates has been established as an effective treatment, although significant mortality and morbidity remain. In Curaçao, surfactant became available as a therapeutic option in 1994. A retrospective cohort study was performed to describe the results of surfactant treatment in premature newborns with RDS in Curaçao between 1994 and 1998. Of 429 infants admitted to the study hospital in this period, 7.5 (n = 32) developed RDS and were treated with surfactant. Twenty-five per cent (n = 8) of these infants died, most of them in the first year of surfactant treatment. Twenty-eight per cent (n = 9) developed bronchopulmonary dysplasia (BPD), the most frequently observed complication. The highest incidence of BPD (44) was found in the very low birth weight infants (750-1500 g); all infants with BPD were 27-30 weeks of gestational age. The duration of ventilator dependence was significantly associated with the development of BPD (p < 0.05). No other risk factors for complications during the treatment course could be identified. The mean time between birth and the first surfactant treatment was more than nine hours. In this study, we found low incidence rates of RDS and BPD, and a considerable mortality in surfactant treated newborns. This pilot study shows that surfactant treatment of premature infants is feasible in Curaçao. Earlier administration of surfactant, preferably within 2-3 hours after birth, is expected to lower the risk of death and oxygen dependence.

User perceptions on coastal resource state and management options in Curaçao

Public environmental awareness and support for management measures are key determinants of the scope for successful implementation of natural resource management. To assess user perceptions and opinions on resource state and potential management options for the coastal zone of Curaçao, we queried 250 coastal resource users from around the island (sport divers, part-time artisanal fishermen and recreational boaters) using questionnaires. There is wide awareness of a long-term decline in coastal resource condition as measured by various indicators. Even among fishermen there was wide awareness of anthropogenic contributors to the decline, broad agreement of management measures required and a general willingness to contribute to management by means of annual license fees. Some of the more salient findings include the endorsement by fishermen of the current ban on spearfishing (81%), the regulation of the beach seine fishery for scad (77%), the introduction of fish reserves (72%), special protection for sea turtles (90%), conch (82%), and lobsters (72%), and notable support for gradual elimination of trap fisheries (45%). Also, both divers (65%) and boaters (92%) expressed the importance to them of an attractive coastline, with both groups expressing preference for natural (un-built) coastline (>74%) above other categories. Management based on the concept "user pays", as already implemented in the Netherlands Antilles on Saba and Bonaire, is well supported by the resource user public. A review of other main constraints such as finances and institutional capacity, shows that conditions are quite favorable for implementation of new legislation. Modem coral reef management is urgently needed in Curaçao to safeguard a key natural resource and concerted action is called for on the part of government agencies, legislators and elected officials.
