Consolidation of a Learned Skill Correlates with Dopamine SPECT Uptake in Early Parkinson's Disease

BACKGROUND AND PURPOSE: Basal ganglia play a pivotal role in procedural memory. However, the correlation between skill learning and striatal 123I-ioflupane uptake in Parkinson's disease (PD) has not been reported previously. Our objective was to determine whether visuomotor skill learning is associated with striatal 123I-ioflupane uptake in early PD. METHODS: We designed a case–control study to assess learning and consolidation of a visuomotor learning task (mirrored drawing of star-shaped figures) performed on two consecutive days by early-PD patients (disease duration 0.18) other than the score on part III of the Movement Disorders Society Unified Parkinson's Disease Rating Scale, which was higher in the PD patients (mean±SD: 15.0±10.4 vs. 1.3±1.1, p 0.5), whereas PD patients showed a lower consolidation index for the time per trial (p=0.009). Moreover, this performance was correlated with uptake in the right caudate nucleus (Spearman's rho=0.82, p=0.007) and the right striatum (Spearman's rho=0.67, p=0.049), including when multiple linear regression adjusting for the levodopa equivalent daily dose was performed (p=0.005 for the caudate nucleus and p=0.024 for the striatum). CONCLUSIONS: This study provides evidence of a correlation between procedural memory impairment and striatal dopaminergic dysfunction in early PD.

Paediatric and perinatal HIV/AIDS in Jamaica: an international leadership initiative, 2002-2007 / VIH/SIDA pediátrico y perinatal en Jamaica: iniciativa de liderazgo internacional, 2002-2007

BACKGROUND: Paediatric and Perinatal HIV/AIDS remain significant health challenges in the Caribbean where the HIV seroprevalence is second only to Sub-Saharan Africa. METHOD: We describe a collaborative approach to the prevention, treatment and care of HIV in pregnant women, infants and children in Jamaica. A team of academic and government healthcare personnel collaborated to address the paediatric and perinatal HIV epidemic in Greater Kingston as a model for Jamaica (population 2.6 million, HIV seroprevalence 1.5%). A five-point plan was utilized and included leadership and training, preventing mother-to-child transmission (pMTCT), treatment and care of women, infants and children, outcomes-based research and local, regional and international outreach. RESULTS: A core group of paediatric/perinatal HIV professionals were trained, including paediatricians, obstetricians, public health practitioners, nurses, microbiologists, data managers, information technology personnel and students to serve Greater Kingston (birth cohort 20 000). During September 2002 to August 2007, over 69 793 pregnant women presented for antenatal care. During these five years, significant improvements occurred in uptake of voluntary counselling (40% to 91%) and HIV-testing (53% to 102%). Eight hundred and eighty-three women tested HIV-positive with seroprevalence rates of 1-2% each year. The use of modified short course zidovudine or nevirapine in the first three years significantly reduced mother-to-child transmission (MTCT) of HIV from 29% to 6% (RR 0.27; 95% CI - 0.10, 0.68). During 2005 to 2007 using maternal highly active antiretroviral therapy (HAART) with zidovudine and lamivudine with either nevirapine, nelfinavir or lopinavir/ritonavir and infant zidovudine and nevirapine, MTCT was further reduced to an estimated 1.6% in Greater Kingston and 4.75% islandwide. In five years, we evaluated 1570 children in four-weekly paediatric infectious diseases clinics in Kingston, St Andrew and St Catherine and in six rural outreach sites throughout Jamaica; 24% (377) had HIV/AIDS and 76% (1193) were HIV-exposed. Among the infected children, 79% (299 of 377) initiated HAART, resulting in reduced HIV-attributable childhood morbidity and mortality islandwide. An outcomes-based research programme was successfully implemented. CONCLUSION: Working collaboratively, our mission of pMTCT of HIV and improving the quality of life for families living and affected by HIV/AIDS in Jamaica is being achieved.

ANTECEDENTES: El VIH/SIDA pediátrico y el perinatal continúan siendo retos significativos para la salud en el Caribe, donde la seroprevalencia de VIH ocupa el segundo lugar tras el África Subsahariana. MÉTODO: Se describe un enfoque colaborativo para tratamiento, prevención y cuidado de embarazadas, bebés y niños en Jamaica. Un equipo de personal académico y gubernamental vinculados a la salud, colaboraron para abordar la epidemia de VIH pediátrico y perinatal en Greater Kingston, como modelo para Jamaica (población de 2.6 millones, 1.5% seroprevalencia VIH). Se utilizó un plan de cinco puntos que incluyó liderazgo y entrenamiento, prevención de la transmisión madre a hijo (PTMAH), tratamiento y cuidado de mujeres, bebés y niños, investigaciones basadas en resultados, y outreach local, regional e internacional. RESULTADOS: Un grupo básico de profesionales del VIH pediátrico/perinatal, que incluía pediatras, obstetras, trabajadores de la salud, enfermeras, microbiólogos, administradores de datos, así como personal y estudiantes de la tecnología de la información, fue entrenado para servir en Greater Kingston (cohorte de nacimiento 20 000). De septiembre de 2002 hasta Agosto de 2007, más de 69 793 embarazadas se presentaron para recibir atención prenatal. Durante estos cinco años, tuvieron lugar mejoras significativos en cuanto a la recepción de asesoramiento (40% to 91%) y pruebas (53% to 102%) de VIH voluntarios. Ochocientos ochenta y tres mujeres resultaron VIH positivas en las pruebas, con tasas de seroprevalencia de 1-2% cada año. El uso de un ciclo corto modificado de zidovudina o nevirapina en los primeros tres años, redujo la transmisión madre a hijo (TMAH) de VIH significativamente de 29% a 6% (RR 0.27; 95% CI - 0.10, 0.68). Durante el 2005 hasta 2007, usando terapia antiretroviral altamente activa (TARAA) materna, con zidovudina y lamivudina con nevirapina, nelfinavir o lopinavir/ritonavir y nevirapina y zidovudina para niños, la TMAH se redujo a un estimado de 1.6 % en Greater Kingston y a .75% a lo largo de la isla. En cinco años, evaluamos 1570 niños en cuatro clínicas infecciosas pediátricas semanales en Kingston, Saint Andrew y Saint Catherine, así como en seis otros lugares destinados al servicio comunitario (outreach) por toda Jamaica; 24% (377) tenían VIH/SIDA y 76% (1193) estaba expuestos al VIH. Entre los niños infectados, 79% (299 de 377) iniciaron el TARAA, lo que trajo como resultado una reducción de la mortalidad y la morbilidad infantil atribuible al VIH, en todo el país. Se implementó exitosamente un programa de investigación basado en resultados. CONCLUSIÓN: Trabajando en colaboración, estamos logrando nuestra misión de prevenir la TMAH del VIH, y mejorar la calidad de vida de las familias que viven afectadas por el VIH/SIDA en Jamaica.

Medical paediatric admission patterns at the University Hospital of the West Indies: issues for future planning / Patrones de ingresos médico-pediátricos en el Hospital Universitario de West Indies: agenda para planes futuros

An understanding of the epidemiological trend in hospital admissions, including morbidity and mortality patterns and the economic impact, is critical for healthcare planning and appropriate resource allocation. Data were collected on all admissions to the paediatric unit of the University Hospital of the West Indies during the period 1999. Each observation included demographic data, admission and discharge data and billed cost of care. There were 1350 admissions (570 female and 715 male, p < 0.001). Admissions [quot ]lows[quot ] were observed in February, April and July; minor peaks in March and June and the major peaks between October and January coincided with admissions due primarily to respiratory conditions. The evening shift was generally the busiest, with the night shift having the lowest average number of admissions in any one-week period Occupancy was uniformly high between November and April, with minor lows in May and August/September. The total cost for a typical patient was J$9708 per admission and the total daily cost for a typical patient was J$1823 (US$1 = J$39 in 1999). The findings could assist with resource allocation and rationalization of health services.

Entender la tendencia epidemiológica en los ingresos al hospital, incluyendo los patrones de morbilidad y mortalidad así como el impacto económico, resulta fundamental a la hora de planificar la atención a la salud y asignar los recursos de forma apropiada. Los datos fueron recopilados en todos los ingresos a la unidad pediátrica del Hospital Universitario de West Indies durante el periodo de 1999. Cada observación incluyó los datos demográficos, los datos de ingreso y alta, y los costos facturados para la atención médica. Hubo un total de 1350 ingresos (570 hembras y 715 varones, p < 0.001). Los periodos “bajos” de ingresos se observaron en febrero, abril, y julio; los picos menores en marzo y junio, y los picos mayores en octubre y enero coincidían con ingresos debidos fundamentalmente a problemas respiratorios. El turno de la tarde-noche era generalmente el más ocupado, teniendo el turno de la noche el número promedio más bajo de ingresos en cualquier período de una semana. La ocupación del hospital se mantuvo uniformemente alta entre noviembre y abril, con bajas en los meses de mayo y agosto/septiembre. El costo total de un paciente típico fue de J$9708 (dólares jamaicanos) por ingreso, y el costo total diario por cada paciente típico fue de J$1823 (US$1 = J$39 en 1999). Los hallazgos podrían ser de utilidad en relación con la asignación de recursos y la racionalización de los servicios de salud.

Student self-assessment in a paediatric objective structured clinical examination / Autoevaluación del Estudiante en un Examen Clínico Objetivo Estructurado de Pediatría

OBJECTIVE: The objective structured clinical examination (OSCE) has been recognized not only as a useful assessment tool but also as a valuable method of promoting student learning. Student self-assessment is also seen as a means of helping students recognize their strengths and weaknesses, understand the relevance of core learning objectives and to take more responsibility for each stage of their work The authors sought to evaluate the accuracy of medical student self-assessment of their performance in the paediatric clerkship OSCE and thus obtain preliminary data for use in programme strengthening. DESIGN AND METHODS: A self-administered questionnaire was completed by successive groups of students immediately after the OSCE at the end of each clerkship rotation. Students assessed their performance at each station, using a performance rating scale. Performance data were summarized using descriptive and non-parametric tests. Basic statistical analysis of the Likert items was conducted by calculatingfrequencies, means and standard deviations. Regression analysis was used to correlate self-reported rating and actual performance in each station. A p value of < 0.05 was considered significant. Eighty-one students (92) completed the questionnaire. RESULTS: Fifty-eight (72) of the students achieved greater than minimum competence in their overall scores. Significant positive correlation (p < 0.05) between student self-rating and actual score was noted- among the following stations: technical skills, cardiovascular examination, assessment of dysmorphism, dermatology, communication and photographic interpretation stations. Students overestimated their performance in the gastrointestinal examination, radiological and arterial blood gas interpretation. Students underestimated their performance in the following: respiratory system, examination of the head, developmental and nutritional assessment. CONCLUSIONS: The findings highlight the perceived strengths and weaknesses in clinical competence and self-assessment skills and provide direction for programme training needs

Objetivo: El examen clínico objetivo estructurado (ECOE) ha sido reconocido no sólo como una herramienta de evaluación útil, sino también como un valioso método para promover el aprendizaje del estudiante. La auto-evaluación estudiantil es vista también como un medio de ayudar a que los estudiantes reconozcan sus fortalezas y debilidades, entiendan la relevancia de los objetivos de aprendizaje comunes, y tomen más responsabilidad en cada etapa de su trabajo. Los autores buscaron evaluar la exactitud de la auto-evaluación del rendimiento del estudiante de medicina en la estación pediátrica del ECOE, obteniendo de eso modo datos preliminares a ser usados en el fortalecimiento del programa. Diseño y métodos: Una autoencuesta fue completada por grupos sucesivos de estudiantes inmediatamente después del ECOE al final de cada rotación de las estaciones. Los estudiantes evaluaron su rendimiento en cada estación, usando una escala de evaluación del rendimiento. Los datos del rendimiento fueron resumidos utilizando tests descriptivos y no paramétricos. El análisis estadístico básico de los ítems tipo Likert se llevó a cabo calculando las frecuencias, medias y desviaciones estándar. El análisis de regresión fue usado para correlacionar la calificación autoreportada con el desempeño real en cada estación. Un valor de p < 0.05 fue considerado significativo. Ochenta y un estudiantes (92%) respondieron la encuesta. Resultados: Cincuenta y ocho (72%) de los estudiantes lograron un rendimiento por encima del mínimo en sus resultados (puntuaciones) generales. Se observó una correlación positiva significativa (p < 0.05) entre la autocalificación del estudiante y el resultado real en las estaciones siguientes: habilidades técnicas, examen cardiovascular, evaluación del dismorfismo, dermatología, y las estaciones de comunicación e interpretación fotográficas. Los estudiantes encima de-estimaron su actuación en el examen gastrointestinal, la interpretación de gas de sangre radiológica y arterial. Los estudiantes subvaloraron su competencia en las siguientes estaciones: sistema respiratorio, examen de la cabeza, evaluación del desarrollo y la nutrición. Conclusiones: Los hallazgos resaltan las fortalezas y las debilidades percibidas en la competencia clínica y la autoevaluación de las habilidades, a la par que proveen dirección a las necesidades de entrenamiento en los programas.

Nevirapine-associated rash in a Jamaican child with HIV/AIDS

Nevirapine is one of the first line antiretroviral agents used in the treatment of HIV/AIDS as well as for prophylaxis against mother-to-child transmission of HIV As antiretroviral medication becomes more available it is important for physicians to recognize the major clinical toxicities of these medications. We report a HIV-infected infant who developed a rash with systemic symptoms in association with nevirapine administration

HIV/AIDS following sexual assault in Jamaican children and adolescents: a case for HIV post-exposure prophylaxis

Reported sexual assault in Jamaica is highest among children and adolescents. The risk of HIV transmission after sexual assault, although small, may be significant in certain circumstances, and it is therefore reasonable that post-exposure prophylaxis should be offered. These HIV transmission rates are similar to those of healthcare workers after occupational exposure to known HIV-infected blood for which routine post-exposure prophylaxis is recommended. We present a case series of children/adolescents with HIV/AIDS post-sexual assault and make the case for post-exposure prophylaxis for HIV infection following sexual assault

Tuberculosis, chickenpox and scabies outbreaks in an orphanage for children with HIV/AIDS in Jamaica

OBJECTIVES: The aim of this study is to describe the investigation and management of outbreaks of acute tuberculosis, varicella zoster virus and scabies in a residential facility for children with HIV/AIDS. METHOD: A review of the results and management for diagnosed cases of acute TB (four between 2001 and 2002) as well as varicella zoster virus (15) and scabies (14) (concurrent in March--June 2003), in a residential facility housing 24 abandoned children with HIV/AIDS was conducted. Outbreak control methods and challenges are described The modified WHO criteria were used for TB diagnosis. The diagnoses of varicella and scabies were entirely clinical. RESULTS: Of the surviving 22 children, 12 (mean age 8 years 2 months) were female, and 10 (mean age 5 years 6 months) were male. Full immunization (primary series) was documented for 16 children, partial in one child, unknown status was documented in five children. One child had received varicella vaccine previously. Eleven (50) children had been receiving antiretroviral triple therapy since 2002 (all in Centers for Diseases Control immunological categories 2-3). Two of the four children with tuberculosis died between 2001 and 2002; these were not on antiretroviral therapy--the 2 survivors are still on antiretroviral therapy. All staff mantoux test results were negative. Fifteen (68) children developed chickenpox as well as three caregivers. The index case was a 13-year-old resident attending a nearby school with HIV negative children. This varicella outbreak went on to affect household members for the caregivers as well as other residential facilities nearby. Scabies affected 14 children (no caregivers); the index cases were most likely three new child residents who entered the institution in 2002 (from other homes) with histories of scabies infestation. Chickenpox and scabies dual infection occurred in seven (31) of residents. No cases of herpes zoster, disseminated varicella infection or death because of varicella occurred Diagnosed cases of chickenpox were treated with oral acyclovir Knowledge about these disease outbreaks and their control was generally lacking. CONCLUSIONS: Improvement in immunization coverage for children and staff as well as educating staff about infectious disease outbreaks, is necessary for effective control. Appropriate screening for infection/disease for all susceptible persons is essential along with timely reporting of outbreaks/reportable diseases. There is need for in

Tuberculosis and HIV co-infections in Jamaican children

BACKGROUND: There has been a worldwide increased prevalence of tuberculosis (TB) in recent years, with a similar trend observed in Jamaica and more recently in children admitted to the University Hospital of the West Indies, Jamaica. Data regarding paediatric TB, especially as it relates to all aspects of HIV co-infection, are needed from developing countries in diverse geographic settings to enhance prevention and treatment policies (National Institutes of Health, Office of AIDS Research, FY 2005 Budgetary Planning Meeting, March 11, 2003, Washington, DC). OBJECTIVE: To determine associated factors and outcomes of tuberculosis in HIV-infected and noninfected children in Jamaica. METHOD: We reviewed records of children aged 0 - 12 years attending the University Hospital of the West Indies during January 1999 to December 2002. Associated factors and outcomes in HIV-infected and HIV-negative cases with TB were compared using exact statistical methods to account for the small number of children and an adjustment for multiple testing. TB diagnosis was determined using modified World Health Organization (WHO) criteria. RESULTS: There was a significant increase of active TB cases from 1999 to 2002 with 24 children diagnosed over this period All 24 children (100) had received the Bacillus-Calmette-Guerin (BCG) vaccine. Eleven (46) of these were HIV-infected, all via mother-to-child transmission. HIV-infected children were statistically more likely to be older than non-infected children (mean 4.2 vs 2.6 years), and also to have failure to thrive, digital clubbing, hepatomegaly, splenomegaly, generalized adenopathy and negative Mantoux tests. Appropriate in-hospital anti-TB therapy was given. Hospital stay was longer (median 7.4 vs. 2.8 months) and death was more likely (7/11 vs 2/13) in HIV-infected vs non-infected children. Triple antiretroviral therapy was given in three of the 11 HIV-infected cases and this markedly improved outcome. Household family members with active TB were identified in twelve cases. CONCLUSIONS: HIV and TB co-infection is an increasing problem in Jamaican children. Severity of illness and death is greater in HIV-infected children, despite appropriate anti-TB therapy. Antiretroviral drugs must be made available to this population. Efforts must be enhanced to reduce mother-to-child-transmission of HIV/AIDS and to strengthen the public health management of TB (contact tracing and completion of TB therapy by directly observed therapy)

Antiretroviral drug therapy in HIV-infected Jamaican children

BACKGROUND: The study describes a cohort of HIV-infected Jamaican children receiving antiretroviral therapy (ART) and reports the outcome. METHOD: An observational prospective study was conducted on HIV-infected Jamaican children receiving anti retroviral drug therapy (ART). The outcome measures, weight, height, hospital admissions and length of stay were compared at initiation and within six months of commencing ART. RESULTS: There were 37 (33.6) of 110 HIV-infected children receiving ART during 2001 to 2003. The median age at commencement was six years (age range 1-16 years) with 54.1 (20) males and 48 AIDS orphans. Care was home-based for 68 of all cases with the University Hospital of the West Indies managing 27 (73) and the Bustamante Hospital for Children 10 (27). The distribution by Centers for Disease Control and Prevention (CDC) clinical class was C (severely symptomatic), 22 (59.5); B (moderately symptomatic), 8 (21.6); A (mildly symptomatic), 6 (16.2) and N (asymptomatic), one (2.7). Among 14 (36) children with CD4 counts, 8 (57) were CDC immune class 2 (moderate immunodeficiency) and 6 (43) were class 3 (severe immunodeficiency). After commencing ART the mean difference in admissions was--1.5+/-2.55 admissions (95 CI -2.3, -0.6; p < 0.001) and in length of stay was -12.9+/-21 day (95 CI -19.9, -0.5.9; p < 0.001). Antiretroviral therapy resulted in a mean weight gain of 2.8 kg+/-4.9 kg (95 CI 1.0, 4.5; p < 0.003) and a mean gain in height of 1.7 cm+/-2.6 cm (95 CI 0.6, 2.8; p < 0.003). Five children required second line therapy. CONCLUSION: The introduction of antiretroviral therapy has resulted in improved outcomes and is being initiated in older children cared for mainly at home. Limitations in accessing affordable second line agents underscore the need for compliance with first line therapy

CDC-defined diseases and opportunistic infections in Jamaican children with HIV/AIDS

OBJECTIVE: To document the frequency of Centers for Disease Control and Prevention (CDC)-defined clinical conditions, opportunistic and co-infections among children with HIV/AIDS. METHODS: This prospective, observational study reports the findings of 110 HIV-infected children followed in multicentre ambulatory clinics during September 1, 2002, to August 31, 2003, from the 239 children enrolled in the Kingston Paediatric and Perinatal HIV/AIDS Programme, Jamaica. We describe the clinico-pathologic characteristics of these children with HIV/AIDS, using the CDC criteria. RESULTS: The client distribution by clinic site was as follows: the University Hospital of the West Indies, 71 (64.6), Bustamante Hospital for Children, 23 (20.9), Comprehensive Health Centre 13 (11.8/) and Spanish Town Hospital, 3 (2.7). The median age of the 110 children with HIV/AIDS was 6.0 years (range 0.9-17.5). Mode of transmission was primarily mother-to-child (88.0) and only 4 maternal/infant pairs received antiretroviralprophylaxis. Grouped by CDC category: 17 (15.4) were asymptomatic (N), 22 (20.0) mildly symptomatic (A), 30 (27.3) moderately symptomatic (B) and 41 (37.3) severely symptomatic (C). The most common CDC-defining symptoms were lymphadenopathy (12, 42.8) and asymptomatic (6, 21.4) in category N; lymphadenopathy (30, 29.7), dermatitis (20, 19.8) and persistent or recurrent upper respiratory tract infections (20, 19.8) in category A; bacterial sepsis (18, 34.6) and recurrent diarrhoea (11, 21.2) in category B; and wasting (28, 30.0), encephalopathy (26, 27.9), and serious bacterial infections (15, 16.1) in category C; Pulmonary tuberculosis (7, 7.5) and Pneumocystis (jiroveci) carinii pneumonia; (5, 5.4) were the most frequent opportunistic infections. Streptococcus pneumoniae (10, 30.3) was the most common invasive bacterial pathogen causing sepsis and Escherichia coli (14, 34.2) was the most common bacterial pathogen causing urinary tract infections, among the cohort. Thirty-three per cent commenced antiretroviral drugs (ARVs). There were 57 hospitalizations and five deaths. CONCLUSIONS: The study is an important step toward documentation of the natural history of paediatric HIV/AIDS in a primarily ARV-naive population from a developing country. It promotes training in paediatric HIV management as we move toward affordable access to antiretroviral agents in the wider Caribbean and the implementation of clinical trials

Uptake of interventions, outcomes and challenges in caring for HIV-exposed infants in Kingston, Jamaica

BACKGROUND: In a few Caribbean islands, prevention of mother-to-child transmission (pMTCT) of HIV with zidovudine prophylaxis has reduced transmission rates from 27 - 44 to 5.5 - 9 . OBJECTIVES: To highlight the uptake of interventions, preliminary outcomes and challenges in caring for HIV-exposed infants in a pMTCT HIVprogramme in a resource-limited setting. METHOD: A cohort of HIV-infected pregnant women were identified at the leading maternity centres in Greater Kingston through HIV counselling and testing and enrolled in the Kingston Paediatric and Perinatal HIV/AIDS Programme. Antiretroviralprophylaxis with zidovudine or nevirapine was given to the HIV-positive women and their newborns along with formula feeding. Some infants were enrolled retrospectively and followed irrespective of whether they had or had not received antiretroviral prophylaxis. A multidisciplinary team at the paediatric centres supervised protocol-driven management of the infants. Infants were followed for clinical progress and definitive HIV-infection status was to be confirmed at 18 months of age by ELISA or the Determine Rapid Test. RESULTS: During September 1, 2002 through August 31, 2003, 132 HIV-exposed infants were identified. For those infants prospectively enrolled (78), 97 received antiretroviral prophylaxis and 90 were not breastfed For all HIV-exposed children, 90 received cotrimoxazole prophylaxis and 88 continued follow-up care. Ninety-two per cent of all the infants remained asymptomatic and five died; of these deaths one is possibly HIV-related (severe sepsis at 11 weeks). This infant was retrospectively identified, had received no antiretroviral prophylaxis and was breastfed The main programme challenges, which were overcome, included the impact of stigma, compliance with antiretroviral chemoprophylaxis, breast-milk substitution and follow-up care. Financial constraints and laboratory quality assurance issues limited early diagnosis of HIV infection. CONCLUSION: Despite the challenges, the expected outcome is to prevent 50 new cases of HIV/AIDS in children living in Greater Kingston per year (300 over six years)

Socio-demographic characteristics of HIV-exposed and HIV-infected Jamaican children

BACKGROUND: In the face of the continuing pandemic of HIV/AIDS, the burden of the disease is now largest in the resource-poor developing world. The Joint United Nations Programme on HIV/AIDS (UNAIDS) has listed the adult prevalence rate for the Caribbean as second only to Sub-Saharan Africa. OBJECTIVE: To document the socio-demographic characteristics of paediatric and perinatal HIV/AIDS in Kingston, Jamaica. METHODS: A cohort of HIV-infected pregnant women were identified at the leading maternity centres in Kingston and St Catherine and were enrolled in the Kingston Paediatric and Perinatal HIV/AIDS Programme. Infants born to mothers within the programme were prospectively enrolled. Infants and children identified after delivery, whether HIV-exposed or infected, were also enrolled (retrospective group). All were followed according to standardized protocols. RESULTS: We report on a total of 239 children, 78 (prospective group) and 161 (retrospective group). Among the retrospective group, 68 were classified as infected. For the prospective group, the patients were recruited within twenty-four hours of birth in 98.7 of cases, whereas in the retrospective group, the median age of recruitment was 2.6 years. The median age of the mother was 27 years and that of the father was 33 years. There were seven teenage mothers. Twenty-six per cent of the children were in institutional care. Family size ranged from one to nine children--the median was two children. For those parents where occupation was reported, the majority held semi-skilled or unskilled jobs. Patients attended their regional clinics. CONCLUSION: HIV/AIDS represents a significant human and financial burden on a developing country such as Jamaica and this underscores the need for urgent and sustained interventions to stem the epidemic

Chronic disease control and compliance--the HOPE worldwide Jamaica experience

HOPE worldwide Jamaica has provided mobile curative and preventative services to fourteen rural government clinics since 1994. The patient records of 1,091 chronic disease patients, aged >30 years between January and December 1999 were reviewed. They were all above 30 years of age with an average age of 64 years; 81were female and 60were hypertensive, 16diabetic and 24had both diabetes and hypertension. There were 2,390 visits for hypertension, with an average of 2 visits per patient. Thirty-four per cent of patients had BP of < or = 140/90 mmHg while 43had BP <160/ 95 mmHg. Compliance was defined as daily consistency in taking prescribed medication. Forty-four per cent of hypertensives were non-compliant at the time of their visit. Anti-hypertensive treatment included thiazide diuretics (65), reserpine (50), ACE inhibitors (30) and alpha-methyldopa (5). There were 1,129 visits for diabetes, with an average of 2 visits per patient. Twenty-four per cent of diabetic patients were controlled to fasting blood glucose FBG levels of <6.7 mmol/l and 38controlled to (FBG) levels <8 mmol/l. Thirty per cent of diabetics were non-compliant at the time of their visit. The most frequently used oral hypoglycaemic agents were metformin (78), glyburide (43) and chlorpropamide (30). Fourteen per cent of diabetics were on treatment with insulin 70/30 (12) and lente insulin (2). Electrocardiograms (ECG) were done on 24(n=267) of patients in the previous two years. Thirty-six per cent had evidence of left ventricular hypertrophy and 15had evidence of ischaemic heart disease. The level of blood pressure and blood glucose control is inadequate, despitethe provision of regular monitoring, surveillance and improved access to pharmaceuticals. It is perceived that poor socioeconomic conditions, lack of education, cultural beliefs, in addition to other factors, continue to militate against improved compliance and control.
