Does group B streptococcal infection contribute significantly to neonatal sepsis in Antigua and Barbuda?

Group B streptococcus is the most common cause of neonatal sepsis in the United States of America (USA). This study was undertaken to determine the contribution of group B streptococcus to neonatal septicaemia in Antigua and Barbuda. From 1994 to 2002, there were about 12 000 births, with 2500Special Care Nursery admissions, 1100 (44%) with potential neonatal septicaemia. Blood cultures were done in 433/1100 (39%) and cerebrospinal fluid cultures in 52/1100 (5%). Positive cultures were seen in 41/433 (9.5%) with group B streptococcus in 1/41 (2.4%), streptococcus “species” in 3/41 (7.4%) and positive cerebrospinal fluid cultures were seen in 2/52 (one group B streptococcus) giving 5 per 12 000 or 0.4 cases per 1000 babies. Vaginal cultures from 1994 to 2002 revealed group B streptococcus in 14/163 (8.6%) of positive bacterial cultures. A sample of pregnant women from a private office had positive culture for group B streptococcus in 2/120 (1.7%). The prevalence rate of carriage (15 to 40%) and infection (1.7 to 4 per 1000 babies) was much higher in the USA in the same period. Universal screening of mothers for group B streptococcus may not be as necessary or cost-effective inAntigua and Barbuda.

Los estreptococos del grupo B son la causa más común de sepsis neonatal en los Estados Unidos (EE.UU.). Este estudio se llevó a cabo con el propósito de determinar en que medida los estreptococos del grupo B contribuyen a la septicemia neonatal en Antigua y Barbuda. Desde el año 1994 hasta el2002, hubo alrededor de 12000 nacimientos, con 2500 ingresos a la Guardería de Cuidados Especiales, 1100 (44%) con septicemia neonatal potencial. Se realizaron cultivos de sangre en 433/1100 (39%) y cultivos del líquido cefalorraquídeo cerebroespinal) en 52/1100 (5%). Seobservaron cultivos positivos en 41/433 (9.5%) con estreptococos B en 1/41 (2.4%), “especies“ de estreptococos en 3/41 (7.4%), y se observaron cultivos cefalorraquídeos positivos en 2/52 (1 de estreptococosdel grupo B), para 5 por 12 000 ó 0.4 casos por 1000 recién nacidos. Los cultivos vaginales desde el año 1994 al 2002 revelaron estreptococos del grupo B en 14/163 (8.6%) de los cultivosbacterianos positivos. Una muestra de mujeres embarazadas – provenientes de una oficina privada – tuvo un cultivo positivo para estreptococos del grupo B en 2/120 (1.7%). La tasa de prevalencia de portación (15 a 40%) e infección (1.7 a 4 por 1000 recién nacidos) fue mucho más alta en los EE.UU. en el mismo período. El pesquisaje universal de madres en relación con el estreptococo de grupo Bpuede no ser tan necesario o costo-efectivo en Antigua y Barbuda.

Comparison of general anaesthesia and spinal anaesthesia for caesarean section in Antigua and Barbuda

Regional anaesthesia has become the anaesthetic of choice for Caesarean section (CS) in developed countries, with use extended to smaller, less developed countries in the past decade. This study is a comparison of maternal and neonatal outcomes comparing general anaesthesia (GA) and the early experience with spinal anaesthesia (SA) for CS in Antigua and Barbuda. Data obtained included maternal age, gravidity, parity, indication for operation, emergent versus routine operation and type of anaesthesia used. Outcome data comprised estimated blood loss, transfusion requirement, length of stay, postoperative wound infection for mothers. Data obtained for babies included birthweight, one and five minute Apgar scores, neonatal special care unit admission or perinatal death. The sample population included 103 CS patients who underwent GA and 45 who underwent SA. There was no difference in age (mean 29.3 vs 29.4 years), gravidity (mean 3.25 vs 3.27), parity (mean 1.74 vs 1.56) or emergency vs routine CS (44.4% vs 49.5%). Mothers who underwent GA had significantly greater estimated blood loss (mean 787 vs 632 mL, p < 0. 02) and rate of transfusion (13.6% vs 2.2%, p < 0. 05). There was a trend toward longer hospital stay (mean 6.86 vs 6.42 days, p = 0. 16) but a lower rate of postoperative wound infection (8.7% vs 20%, p < 0. 10) for mothers who underwent GA. There were no maternal deaths. Babies demonstrated no difference in birthweight (mean 3238 vs 3258 g) but those born to mothers who underwent GA had significantly lower one minute (mean 6.84 vs 8.17, p < 0.0001) and five minute (mean 8.13 vs 8.91, p < 0.001) Apgar scores, with a trend toward more frequent neonatal special care unit admission (26.2% vs 17.7%, p < 0.20) and perinatal death (3.9 vs 0%, p < 0.30). GA and SA appear equally safe, but SA was associated with significantly better outcome for both mothers and babies.

The age-specific incidence of admission to the intensive care unit for acute myocardial infarction in Antigua and Barbuda

This study was done to assess the age-specific incidence of admission for acute myocardial infarction in Antigua and Barbuda from 1990 to 2001. A retrospective review of Intensive Care Unit admissions for possible acute myocardial infarction was performed. Data obtained included age, gender, country of residence, electrocardiogram, creatine kinase results and intensive care unit outcome. There were, 250 admissions, 194 (78%) having data available for review. Acute myocardial infarction was found in 107/194 (55.2%) patients, age 59.9 +/- 13.7 years, 28% female, 70% from Antigua and Barbuda, 90/107 (85%) were between 35 and 75 years old. The incidence would be 7.5 per year or 9.7 per year if the confirmation rate documented was similar for all admissions. With a yearly population of 9555 men age 35 to 75 years in Antigua and Barbuda, with men accounting for 72% of acute myocardial infarctions, the incidence rate was 0.57 (confirmed) to 0.73 (all admissions) per year per 1000 men. For women, the yearly population was 10822 age 35 to 75 years, and the incidence rate was 0.19 to 0.24 per year per 1000 women. The mortality rate was 12/107 (11.2%), with women being older (67 vs 57 years, p = 0.001) and dying more often (17% vs 9%) compared with men. The mortality rate in the Intensive Care Unit was 0.07 per year for men, 0.04 per year for women per 1000 aged 35 to 75 years. In the United States of America (USA), the admission rate is 4.1 for men and 1.8 for women per year per 1000 aged 35 to 75 years; the mortality rate is 1.0 for men and 0.5 for women per year per 1000 aged 35 to 75 years. Rates of admission to the Intensive Care Unit for acute myocardial infarction in Antigua and Barbuda are 20%, and mortality rates are 10% of those reported in the USA.

Sensitivity and specificity of the electrocardiogram in predicting the presence of increased left ventricular mass index on the echocardiogram in Afro-Caribbean hypertensive patients / Sensibilidad y especificidad del electrocardiograma en la predicción de la presencia de aumento del indice de masa ventricular izquierda en el ecocardiograma en pacientes Afro-caribeños hipertensos

Cardiovascular disease is emerging as the leading cause of death in the Caribbean region with hypertension along with diabetes mellitus representing the major causes. Left ventricular hypertrophy associated with hypertension results in a two to fourfold increase in cardiac morbidity and mortality. One hundred and eleven patients, 67% female, mean age 46 years with a mean of seven years since diagnosis, had resting blood pressure, electrocardiogram and sector-focused M-mode echocardiogram performed The electrocardiograms were analyzed for left ventricular hypertrophy using Sokolow-Lyon, Cornell, Romhilts-Estes, 12 lead sum, QRS duration, 12 lead-QRS product and left ventricular strain pattern. The echocardiograms were analyzed for increased left ventricular mass using the formula of Devereux and Reichek indexed to height. The mean systolic blood pressure was 156 mmHg, mean diastolic blood pressure was 97 mmHg on treatment. At least one electrocardiographic criterion for left ventricular hypertrophy was seen in 47/111 (42%) patients and increased left ventricular mass index was seen in 55/111 (50%) patients. Sensitivity, specificity and positive predictive value of the electrocardiogram in predicting increased left ventricular mass index was best for Sokolow-Lyon (31%, 86%, 76%), Cornell (23%, 96%, 88%) and 12 lead-QRS product (30%, 86%, 72%). Sensitivity ranged from 3 to 31%, specificity from 80 to 96% and positive predictive value from 40 to 88%. The electrocardiogram is insensitive in detecting increased echocardiographic left ventricular mass index, as in patients from developed countries, and is less specific for the finding as in African Americans.

La enfermedad cardiovascular está pasando a ocupar el primer plano como causa principal de muertes en la región del Caribe, siendo la hipertensión junto con la diabetes las causas principales. La hipertrofia del ventrículo izquierdo asociada con los resultados de la hipertensión, trae como consecuencia que la morbilidad y la mortalidad cardíacas aumenten de dos a cuatro veces. A ciento once pacientes – el 67% mujeres, con una edad promedio de 46 años y un promedio de siete años transcurridos desde el diagnóstico – se les midió la presión arterial en reposo, y se les hizo un electrocardiograma, así como un ecocardiograma en Modo-M enfocado por sectores. Los electrocardiogramas fueron analizados en busca de alguna hipertrofia ventricular izquierda, usando los criterios de Sokolow-Lyon, Cornell, Romhilts-Estes, la suma de 12 derivaciones, la duración del QRS, el producto del QRS en las 12 derivaciones, y el patrón de tensión ventricular izquierda. Los ecocardiogramas fueron analizados fueron analizados en busca de un aumento de la masa ventricular izquierda, usando la fórmula de Devereux y Reichek indexada por la altura. La media de la presión arterial sistólica fue 156 mmHg, y la media de la presión arterial diastólica fue 97 mmHg en el tratamiento. Al menos un criterio electrocardiográfico de la hipertrofia ventricular izquierda fue visto en 47/111 (42%) pacientes, y el índice de masa ventricular izquierda aumentada, fue visto en 55/111 (50%). La sensibilidad, especificidad y valor predictivo positivo del electrocardiograma en la predicción del índice de masa ventricular izquierda aumentada fue mejor en Sokolow-Lyon (31%, 86%, 76%), Cornell (23%, 96%, 88%) y el producto del QRS en las 12 derivaciones (30%, 86%, 72%). La sensibilidad fluctuó del 3 al 31%; la especificidad, del 80 al 96%; y el valor predictivo positivo, del 40 al 88%. El electrocardiograma es insensible en cuanto a detectar el índice de masa ventricular izquierda aumentada, como...

A fatal case of community acquired methicillin resistant Staphylococcus aureus brain abscess in a previously healthy adolescent / Un Caso Fatal de Estafilococo Dorado Resistente a la Meticilina, Adquirido en la Comunidad, por una Adolescente Previamente Sana

A 16-year-old adolescent presented with fever, lethargy and vomiting associated with mild dehydration. This was followed less than 24-hours later by loss of consciousness, seizures and clinical brain death. She had no prior medical illness, no hospital or frequent antibiotic exposure. There was no evidence of soft tissue or skin infection. Management included intravenous fluids, ampicillin and cefotaxime parenterally, dexamethasone, endotracheal intubation and mechanical ventilation. Her neurologic examination remained unchanged with areflexia, flaccid paralysis and fixed pupils. Post-mortem examination revealed an eight-centimetre right fronto-parietal lobe brain abscess. Cultures were positive for methicillin resistant Staphylococcus aureus. Although formerly a nosocomial pathogen affecting debilitated patients in the hospital setting, S aureus that is methicillin resistant is emerging as a community acquired pathogen affecting previously well patients.

Una adolescente de 16 años de edad se presentó con fiebre, letargia y vómitos, asociados con deshi-dratación ligera. Estos síntomas fueron seguidos en menos de 24 horas por pérdida de conciencia, ataques y muerte clínica del cerebro. Con anterioridad, la paciente no había tenido enfermedad médica, ni hospitalización, ni tratamiento frecuente con antibióticos. No había evidencia de tejidos blandos o infección de la piel. El tratamiento incluyó líquidos intravenosos, ampicilina y cefotaxima de forma parenteral, dexametasona, entubación endotraqueal, y ventilación mecánica. El examen neurológico permaneció invariable con areflexia, parálisis flácida, y pupilas fijas. El examen post-mortem reveló un absceso cerebral de ocho centímetros en el lóbulo fronto-parietal derecho. Los cultivos resultaron positivos al Staphylococcus aureus resistente a la meticilina. Aunque visto an-teriormente como un patógeno nosocomial que afecta a los pacientes debilitados en el entorno hos-pitalario, el S aureus resistente a la meticilina está surgiendo como un patógeno extrahospitalario (ie adquirido en la comunidad) y afecta a pacientes previamente sanos. 1Equivalente acuñado aquí para el término inglés caseness, a saber, criterios que definen el estatus de caso sobre la base de la presencia de sintomatologia clinicamente significativa.

Antibiotic use and overuse for appendicectomy in Antigua and Barbuda

The use of antibiotics for appendicectomy in Antigua and Barbuda, from January 1998 to December 1999, was examined with respect to current Surgical Infection Society guidelines from developed countries. There were 143 cases of appendicectomy performed at Holberton Hospital. The mean patient age and standard deviation (SD) was 28.1 +/- 15.8 years, 57female. Pathology showed inflammed appendix only in 56, peri-appendiceal abscess/perforation in 17, [quot ]fibrosed[quot ] appendix in 10and normal appendix in 17. Postoperative infection (wound infection, fever > three days) was seen in 7/24 (29) of cases with peri-appendiceal abscess/perforation and 2/119 (1.7) of the other cases. A subset of 88 cases had antibiotic use reviewed: 3/88 (3.4) were given no antibiotics, 7/88 (8) were given one antibiotic, 5/88 (5.7) were given two antibiotics, 72/88 (81.8) were given three antibiotics and 1/88 (1.1) was given four antibiotics. Parenteral antibiotics were given a mean and SD of 5.39 +/- 1.94 days followed by oral antibiotics in 18/88 (20.5) cases. Those with appendiceal abscess/perforation were treated parenterally for mean and SD of 6.56 +/- 2.35 days, not significantly different from others. Most frequent antibiotics used were gentamicin, metronidazole and ampicillin/penicillin/cloxacillin/cephradine (81.8). The Surgical Infection Society recommends starting prophylactic antibiotics before surgery, using appropriate spectrum agents for less than 24 hours if not contaminated and less than five days if infected. It may be possible to safely reduce antibiotic use for appendicectomy in Antigua and Barbuda.

Se examinó el uso de los antibióticos en apendicectomías en Antigua y Barbuda, en el período comprendido de enero de 1998 a diciembre de 1999, sobre la base de las guías actuales de la Sociedad de Infecciones Quirúrgicas de los países desarrollados. Un total de 143 casos de apendicectomía fueron atendidos en el Hospital Holberton. La edad media de los pacientes y la desviación estándar (DE) fue 28.1 + 15.8 años, 57% mujeres. La patología mostró apéndice inflamado sólo en el 56% de los casos, absceso periapendicular/perforación en 17%, apéndice "fibroso"en el 10% y apéndice normal en el 17%. Se vio infección postoperatoria (infección de heridas, fiebre>tres días) en 7/24 (29%) de los casos con absceso periapendicular/perforación y 2/119 (1.7%) de los otros casos. A un subconjunto de 88 casos se le revisó el uso de antibióticos: a 3/88 (3.4%) no se les dio antibióticos, 7/88 (8%) recibieron un antibiótico, 5/88 (5.7%) recibieron dos antibiótico, 72/88 (81.8%) recibieron tres antibióticos, y 1/88 (1.1%) recibió cuatro antibióticos. Se suministraron antibióticos parenterales para una media y DE equivalente a 5.39 ± 1.94 días, seguidos de antibióticos orales en 18/88 (20.5%) casos. Los pacientes con absceso apendicular/perforación fueron tratados parenteralmente para una media y DE equivalente a 6.56 + 2.35 días, sin diferencia significativa con respecto a los otros. Los antibióticos más frecuentes fueron la gentamicina, el metronidazol, y la ampicilina/ penicilina/ cloxacilina/ cefradina (81.8%). La Sociedad de Infecciones Quirúrgicas recomienda que se comience con antibióticos profilácticos antes de la cirugía, usando agentes de espectro apropiado durantes menos de 24 horas si no hay contaminación y menos de 5 días si hay infección. El uso de antibióticos en la apendicectomía puede reducirse sin peligro en Antigua.

A comparison of patients relapsing to addictive drug use with non-relapsing patients following residential addiction treatment in Antigua / Una Comparación de Pacientes que Recayeron en el uso Adictivo de Drogas, con Pacientes que no Experimentaron Recaída Tras Seguir un Tratamiento Residencial de la Adicción en Antigua

The outcome of a 29-day residential addiction treatment programme for persons from Antigua and Barbuda with addiction to drugs or alcohol was assessed. All 100 patients entering the drug and alcohol treatment programme at Crossroads Centre Antigua between November 1998 and October 2002 were included. All patients were assessed with regards to drug or alcohol use or abstinence in November 2002 using telephone and mail follow-up as well as informal follow-up with families and other community contacts. Crossroads Centre Antigua is a 35 bed, 29-day residential treatment centre for drug and alcohol addiction serving patients from developed countries (85%) and from the Caribbean region (15%). Patients records were also reviewed to obtain age, gender, ethnicity, drug of choice, years of problematic use, completion of the 29 day programme, family member participation at Crossroads Centre Antigua (a four-day programme) and acceptance of halfway house placement. Of the 100 Antiguan patients admitted, 46 (46%) were abstinent (non-relapsers) at average 20.7+/-14.7 months after treatment. Abstinence did not have to be continuous. Forty-nine were known to be using drug or alcohol (49%) and five (5%) were lost to follow-up and considered to be using drugs (relapsers). Age (37.5 vs 41.1 years), gender (28% vs 22% female), ethnicity (87% vs 87% Afro-Caribbean), years of harmful use (12.7 vs 12.5 years) did not differ significantly between relapsers and non-relapsers. Crack cocaine use (67% vs 65%) and alcohol use (26% vs 31%) as primary addiction did not differ significantly between relapsers and non-relapsers. Relapsers were significantly less likely to complete the 29- day programme (81% vs 100%, p < 0.01), have family members participate at Crossroads (32% vs 54%, p < 0.05) or accept halfway house placement (4% vs 54%, p < 0.001). In conclusion, abstinence was achieved in 46% of those entering treatment, in 51% completing treatment, in 60% whose families participated and in 92% of those accepting halfway house placement

Se evaluó el resultado de un programa de 29 días de tratamiento residencial de la adicción para personas de Antigua y Barbuda adictas a drogas o alcohol. Fueron incluidos todos los pacientes de un total de 100 que entraron a formar parte del programa de tratamiento contra las drogas y el alcohol en el Crossroads Centre Antigua entre noviembre de 1998 y octubre de 2002. Todos los pacientes fueron evaluados en relación con el uso o la abstinencia de drogas o alcohol en noviembre 2002, mediante un seguimiento por vía telefónica o correo, así como a través de un seguimiento informal con familiares u otros contactos en la comunidad. El Crossroads Centre Antigua es un centro de 35 camas para el tratamiento residencial por 29 días de la adicción a las drogas o el alcohol. El centro presta servicios a pacientes de los países desarrollados (85%) y de la región del Caribe (15%). También se revisaron los récords médicos de los pacientes para obtener datos sobre edad, sexo, etnicidad, droga de elección, años de uso problemático, cumplimiento del programa de 29 días, participación de miembros de la familia en el Crossroads Centre Antigua (un programa de cuatro días) y aceptación de su inclusión en una "casa de medio camino." De los 100 pacientes antigüenses admitidos, 46 (46%) eran abstinentes (no recayentes) en un momento determinado, ubicado como promedio 20.7 ± 14.7 meses después del tratamiento. La abstinencia no tenía que ser continua. Se sabía que 49 (49%) estaban usando drogas o alcohol, y cinco (5%) fueron dados por perdidos del seguimiento y de regreso al uso de las drogas (recayentes). La edad (37.5 vs 41.1 años), sexo (28% varones vs 22% hembra), etnicidad (87% vs 87% Afrocaribeños), y los años de consumo perjudicial (12.7 vs 12.5 años) no presentaron diferencias significativas entre los recayentes y los no recayentes. El uso de la cocaína-crack (67% vs 65%) y el uso del alcohol (26% vs.31%) como adicción primaria, no mostró diferencias significativas entre los recayentes y los no recayentes. Los recayentes mostraron una probabilidad significativamente menor en cuanto a completar el programa de 29 días (81% vs 100%, p < 0.01), hacer que miembros de su familia participaran en Crossroads (32% vs 54%, p < 0.05) o aceptar su inclusión en la casa de medio camino (4% vs 54%, p < 0.001). En conclusión, se logró abstinencia en el 46% de los que adoptaron el tratamiento, el 51% de los que completaron el tratamiento, el 60% de aquellos cuyas familias participaron, y el 92% de quienes aceptaron ser ubicados en la casa de medio camino.

How well does fetal ultrasound predict the date of birth in Antigua and Barbuda / Precisión del Ultrasonido Fetal en la Predicción de la fecha de Nacimiento en Antigua y Barbuda?

This study was done to determine the accuracy of fetal ultrasound (U.S.) predicting the estimated date of delivery (EDD) in a primarily Afro-Caribbean population in Antigua and Barbuda. A total of 206 women had retrospective review offetal ultrasound tests done between July 1994 and January 1996. The EDD based on last menstrual period (LMP) was calculated for 104 women with dates and compared with EDD calculated from ultrasound test. These were then compared with actual date of birth from maternity records. For women with unreliable menstrual data (102 women), ultrasound EDD was compared with actual date of birth. Ultrasound EDD demonstrated a trend toward being more accurate than menstrual history EDD, being 10.0 +/- 9.4 (mean +/- standard deviation) days off versus 13.3 +/- 15 days, p = 0.057, (n=104), CI: -0.1, 6.73 days. Ultrasound EDD was within ten days of delivery 60 of the time versus 57 for menstrual history EDD. The average error in estimating EDD was + 1.7 days for ultrasound and + 3.7 days for menstrual history. In women without menstrual history data (n=102), the ultrasound EDD was just as accurate in both the second trimester, 11.8 +/- 9.5 versus 11.4 +/- 10.7 days off (not statistically significant) and the third trimester, 10.0 +/- 8.0 versus 8.1 +/- 7.0 days off (not statistically significant). Fetal ultrasound is marginally better at predicting the date of birth compared with menstrual history but the difference does notjustify routine use for that purpose. When menstrual history is unknown, ultrasound EDD is just as accurate as when menstrual history is known, making it a very useful test

Este estudio fue hecho para determinar la exactitud del ultrasonido fetal (EEUU) en la predicción de la fecha estimada de parto (FEP) en una población principalmente afro-caribeña en Antigua y Barbuda. A un total de 206 mujeres, se les hizo una revisión retrospectiva de las pruebas de ultrasonido fetal, entre julio del 1994 y enero de 1996. La FEP basada en la historia menstrual (UPM) se le calculó a 104 mujeres con fechas, comparándosele luego con la FEP calculada mediante la prueba de ultrasonido. Estas fueron entonces comparadas con la fecha real de nacimiento tomada de los archivos de maternidad. Para las mujeres con datos menstruales inestables (102 mujeres), la FEP basada en ultrasonido fue comparada con la fecha real de nacimiento. La FEP basada en el ultrasonido, mostró una tendencia a ser más exacta que la FEP basada en la historia menstrual, con 10.0 + 9.4 (media + desviación estándar) días de diferencia, frente a 13.3 + 15 días, p = 0.057, (n = 104), CI: -0.1, 6.73 días. La FEP mediante ultrasonido estuvo dentro de los 10 días de parto 60% del tiempo frente al 57% en el caso de la FEP basada en historia menstrual. El error medio de estimación de la FEP fue de + 1.7 días para el ultrasonido y + 3.7 días para la historia menstrual. En mujeres sin datos de historia menstrual (n = 102), la FEP mediante ultrasonido fue igualmente exacta tanto en el segundo trimestre, 11.8 + 9.5 frente a 11.4 + 10.7 días de diferencia, (no significativo estadísticamente) y el tercer trimestre, 10.0 + 8.0 frente a 8.1 + 7.0 días de diferencia, (no significativo estadísticamente). El ultrasonido fetal es marginalmente mejor en predecir la fecha de nacimiento en comparación con el procedimiento basado en la historia mensual, pero la diferencia no justifica el uso rutinario para ese propósito. Cuando se desconoce la historia menstrual, la FEP mediante ultrasonido es tan exacta como cuando se sabe la historia mensual, lo cual la hace una prueba muy útil.

A case control study of the prevalence of perinatal complications associated with fetal macrosomia in Antigua and Barbuda

The prevalence of obstetric, perinatal and neonatal complications associated with fetal macrosomia at Holberton Hospital in Antigua and Barbuda was assessed by a retrospective, case-control study. All babies of birthweight (BW) greater than 4.5 kg born between July 1991 and January 1997 and all babies with BW greater than 4.0 kg born between July 1991 and January 1995, were included. Control babies, were selected from those born on the same day as the index case. Babies of BW > 4.0 kg and babies of BW > 4.5 kg were 5.7 and 1 of births respectively Records were complete for 157 large babies (40 with BW > 4.5 kg) and 157 control babies < 4.0 kg. Mothers of large babies were significantly older, more parous, more likely to have diabetes mellitus, hypertension, and deliver after 40 weeks gestation. At delivery, mothers of large babies were more likely to bleed. Large babies had lower one minute and five minute Apgar score, were more likely to be meconium stained, have respiratory distress, have birth trauma or dystocia and to be admitted to Special Care Nursery. There was no difference in Caesarean section rate, hospital days, neonatal jaundice or mortality. Babies with BW > 4.5 kg had mortality of 7.5 versus 1.8 for those < 4.5 kg. Fetal macrosomia remains a difficult obstetrical problem associated with significant maternal, perinatal and neonatal consequences. Morbidity and mortality are still significant in developed and developing countries alike

Successful pregnancy and delivery after pulmonary autograft operation (Ross procedure) for rheumatic aortic valve insufficiency

A young woman with aortic valve insufficiency secondary to rheumatic heart disease underwent replacement of her diseased aortic valve with her own pulmonary valve and replacement of her pulmonary valve with an aortic cadaver homograft, the Ross procedure. She went on to conceive and deliver a normal infant. The Ross procedure is the operation of choice in a young woman with aortic valve disease, since it avoids anti-coagulation fetal loss, valve deterioration and other maternal risk from pregnancy associated with other valve replacement options

M-mode echocardiographic findings in a contemporary Afro-Caribbean population referred for evaluation of congestive cardiac failure

Congestive cardiac failure is emerging as a significant public health problem around the world, including the Caribbean. Recent reports from developed countries suggest that 30 to 40 of patients with congestive cardiac failure have normal systolic function. This percentage may be even higher in non-Caucasian, non-male populations. This study was undertaken to determine the M-mode echocardiographic findings in a current, consecutive series of Afro-Caribbean patients referred for congestive cardiac failure. There were 165 patients, 51 male, mean and standard deviation (SD) age of 63 +/- 15 years, referred between May 1998 and June 2000. Echocardiographic findings included left atrial size (LA), left ventricular (LV) end systolic (ESD) and end diastolic dimension (EDD), LV posterior wall thickness (PWT) and ventricular septal thickness (VST). LV ejection fraction (EF) was derived. LA > 4 cm, PWT or VST > 13 mm and LVEF < 50 were considered abnormal. Increased LV wall thickness (LV hypertrophy) only was the most frequent finding, 68/165 (41), consistent with possible diastolic dysfunction. If a less restrictive definition for abnormal LV wall thickness, 12 mm, is used, this finding increases to 79/165 (48). Decreased LVEF (LV systolic dysfunction) was seen in 57/165, (35) and was seen in significantly more men (42 versus 29, p < 0.01). Valvular disease was seen in 13/165, 8. Normal findings on echocardiography were found in 27/165 (16), more commonly in women (19 versus 8, p < 0.05) and younger patients (54 years versus 65 years, p < 0.05) and in only 10 if 12 mm is used for LV wall limit. LV hypertrophy was seen in 42 of patients (61 if 12 mm is used for LV wall limit) with systolic dysfunction. Thus, congestive cardiac failure with LV hypertrophy is the most frequent finding in this Afro-Caribbean population, with LV systolic dysfunction in only 35 of patients. These findings are consistent with possible diastolic LV dysfunction due to hypertension as the primary cause of cardiac failure in the population.

Did exclusive breast-feeding and early discharge lead to excessive bilirubin levels in newborns in Antigua and Barbuda?

Hyperbilirubinaemia is a common neonatal problem worldwide and is the leading cause of admission to the Special Care Nursery in Antigua and Barbuda. In 1990, the Innocenti Declaration in support of breast-feeding led to the adoption of the Baby-Friendly Hospital Initiative in many countries of the Caribbean, including Antigua and Barbuda. Comparing 1989 to the years 1992 to 1994, the Special Care Nursery at Holberton Hospital experienced a 40 increase in newborns admitted with hyperbilirubinaemia (peak total bilirubin > 12 mg/dl or 205 mumol/l). A retrospective review of Special Care Nursery and Maternity Ward records was undertaken to determine the incidence and aetiology of hyperbilirubinaemia from 1992 to 1994. There were 3721 infants born in Antigua and Barbuda in those years, 98 of Afro-Caribbean or mixed ancestry. The overall incidence of peak total bilirubin over 12 mg/dl (205 mumol/l) was 12.5 (466/3721), not inconsistent with the reported incidence of 8 to 20 in other countries. However, the incidence of higher levels of hyperbilirubinaemia in Antigua and Barbuda exceeded those reported for other countries. In Antigua and Barbuda, total bilirubin of 15 mg/dl (255 mumol/l) or higher was found in 263 of 3721 infants (7.1) compared to 5.9 in India and 2 of breast-fed infants in the United States of America (USA). Total bilirubin of 20 mg/dl (340 mumol/l) or higher was seen in 91 of 3721 infants (2.5) exceeding reported prevalence in the USA for both African-American and Caucasian infants (1) and equal to the reported prevalence in Asian infants (2). The possible aetiologies of hyperbilirubinaemia in neonates with total bilirubin 18 mg/dl (306 mumol/l) or higher in our patients were investigated. Medical records of 134 of 156 (86) infants having this level of hyperbilirubinaemia were available for review. The possible reason for hyperbilirubinaemia was ABO incompatibility in 4/134 (3), Rh incompatibility in 1/134 (1), prematurity in 12/134 (9) and sepsis neonatorum in 21/134 (16). The hyperbilirubinaemia was idiopathic in 96/134 (71) infants. Newborns in Antigua and Barbuda were discharged 3.7 days after their mothers' admission, with 50 discharged prior to 48 hours of age. Early discharge in developed countries has led to increased readmissions for hyperbilirubinaemia. Following the appointment of a dietitian to supervise breast-feeding, admissions for hyperbilirubinaemia fell by 50 by 1998. These data suggest that exclusive br

Echocardiographic findings in a contemporary Afro-Caribbean population referred for evaluation of atrial fibrillation or flutter

Atrial fibrillation and/or flutter is the most common and the most significant cardiac arrhythmia in the Caribbean. This study is an attempt to determine the echocardiographic findings in a current, consecutive series of Afro-Caribbean patients referred for evaluation of atrial fibrillation and flutter. Between May 1998 and June 2000, 50 patients (mean age 67 years, 58 male) had echocardiograms done. Measurements included left atrial dimension (LA), left ventricular end-systolic dimension (LVESD), LV end-diastolic dimension (LVEDD), LV posterior wall thickness (LVPWT) and ventricular septal thickness (VST). Left ventricular ejection fraction (EF) was calculated. LA > 4 cm, LVPWT or VST > 13 mm, and LVEF < 50 were considered abnormal. Atrial fibrillation was seen in 92, atrial flutter in 8; 60 were chronic, 40 paroxysmal; 56 had congestive heart failure. The most frequent echocardiographic finding was LV hypertrophy (19/50, 38). Left ventricular systolic dysfunction was present in 12/50, 24 (25 with LV hypertrophy also). Valvular disease (abnormal appearing valve, no Doppler study), was seen in 9/50, 18. Normal findings ("lone atrial fibrillation") were seen in 10/50, 20. Increased LA dimension was seen in 39/50, 78. Patients with lone atrial fibrillation were younger (mean 56 years) than those with valvular disease (mean 64 years), LV systolic dysfunction (mean 69 years) and those with LV hypertrophy (mean 72 years). Thus, LV hypertrophy, probably secondary to hypertension, is the most frequent echocardiographic finding, with LV dysfunction (such as seen in coronary artery disease) seen less often. Valvular disease and lone atrial fibrillation rates are similar to rates in developed countries.

The prevalence, aetiology and treatment of congestive cardiac failure in Antigua and Barbuda

A retrospective review of the cases of congestive heart failure admitted to Holberton Hospital in Antigua in 1995 and 1996 was undertaken. Two hundred and ninety-three (293) patients were identified by International Statistical Classification of Diseases, 10th revision (ICD-10) coding as having congestive cardiac failure in the period but only 138 charts were either available or fitted the definition of congestive cardiac failure and these provided the basis for this analysis. The average age of patients admitted for congestive cardiac failure was 69 years (range: 5 months to 99 years), and 63were female. the aetiology of congestive cardiac failure was hypertension (41), ischaemia (33), valvular (12), alcohol related (2), idiopathic (5) and mixed (7). Treatment included diuretics (95), angiotensin converting enzyme inhibitors (78), digoxin (75), nitrates (34), calcium channel blockers (25), other vasodilators (7) and antiarrhythmics (5). Of those with congestive heart failure, diabetes was present in 38, atrial fibrillation in 19, renal insufficiency in 17, elevated cholesterol in 11, obesity in 9and tobacco use in 7. The in-hospital mortality in the 2-year period was 17.4(females 15, males 22, 11 65 years, 14for those with 1 to 3 admissions and 83for those with > 3 admissions, 19for those with atrial fibrillation and 16for those without). The prevalence of congestive cardiac failure utilizing the data analysed in this study (138 patients) was 0.21of the population of the island state but based on the discharge diagnosis using ICD-10 coding it was 0.5; it was 1in the 40 to 65-year-age group and 4in those > 65 years of age. The patients in this study represented only those with New York Heart Association (NYHA) classes III and IV, hence the true prevalence would be higher than recorded here. Congestive cardiac failure is emerging as a significant health problem in Antigua and Barbuda.

Myocardial infarction in Antigua: 1990 to 1995

Between January 1990 and May 1995, 117 patients were admitted to the Intentsive Care at Holberton Hospital, Antigua, for chest pain due to suspected acute myocardial infarction. 39 (45 percent) of 86 patients whose records were available for retrospective review had confirmed (27 patients) or probable (12 patients) acute myocardial infarction. Risk factors identified among the patients included hypertension, diabetes, tobacco smoking, hypercholesterolaemia and obesity. On admission, 82 percent were Killip class I and 18 percent were Killip class II. Medications in the Intensive Care Unit included nitrates, aspirin, calcium and channel blockers, beta-adrenergic blockers, heparin and angiotensin converting enzyme inhibitors (21 percent). No thrombolytic agents were available. THe average hospital stay was 10 days and the in-hospital mortality rate was 13 percent. These data indicate that early mortality from acute myocardial infarction can be reduced in developing countries by early admission to an Intensive Care Unit and use of drugs known to be effective in its treatment.
