Clinical Audit of Sexual Abuse Referral Forms to the Sexual Assault Follow-up and Evaluation Clinic, Nassau, The Bahamas, among Females Aged 13 to 19 Years / Auditoría clínica de los formularios de remisión de abuso sexual a la Clínica de Evaluación y Seguimiento de Agresiones Sexuales, Nassau, Bahamas, entre mujeres de 13 a 19 años

ABSTRACT Objective: To evaluate the adequacy of the documentation of referral forms for sexually abused females aged 13-19 years directed to the Sexual Assault Follow-up and Evaluation (SAFE) Clinic at the Agape Family Medicine Clinic, Nassau, The Bahamas, for interim management. Methods: An approved review was performed on 123 referral forms regarding sexually abused females aged 13-19 years who attended the SAFE Clinic from 2011 to 2015. The exercise focussed on documentation adequacy based on a scoring system developed by the researchers (> 50% was assessed to be adequate; records of the referee's disposition of the patient, the date of the incident and evidence of sexually transmitted infection (STI) screening were considered vital for adequacy). Descriptive and inferential statistics were calculated. Results: The median age of the participants was 14 years (interquartile range: 13-15). Of the 63.4% (78) with documented nationality, 88.5% (69) were Bahamian and 11.5% (9) Haitian. Documentation status did not differ statistically significantly by nationality. Regarding documentation, 74% (91) recorded the name of the patient's school, 59.3% (73) recorded that the patient knew the assailant and 17.9% (22) indicated that the patient did not know the assailant, while 22.8% (28) did not document this latter information. Type of sexual penetration was indicated by 65.9% (81). Of the vital variables, 18.7% (23) recorded the referee's disposition of the patient, 29.8% (36) the date of the incident and 60.2% (74) evidence of STI screening; 7.3% (9) documented all three and 22.8% (28) two. The mean percentage of documentation for vital variables was 49.3% (± 3.6) for the Accident and Emergency (A&E) Department, Princess Margaret Hospital, Nassau, versus 30.5% (± 4.0) for public health clinics (PHCs) (p = 0.001). Overall, 69.9% (86 of 123) of the referral forms were deemed inadequate: 64.7% (33 of 51) from the A&E Department versus 73.4% (47 of 64) from PHCs among the 115 patients who provided referral information. Conclusion: Documentation deficiencies of the sexual abuse referral forms demand reform. Complete and consistent documentation is required.

RESUMEN Objetivo: Evaluar la idoneidad de la documentación de los formularios de remisión para mujeres de 13 a 19 años sexualmente abusadas, dirigidas a la Clínica de Evaluación y Seguimiento de Agresiones Sexuales (ESAS) en la Clínica Ágape de Medicina Familiar, Nassau, Bahamas, para la administración interina. Métodos: Se aprobó una revisión para examinar 123 formularios de remisión con respecto a las mujeres de 13 a 19 años sexualmente abusadas, que asistieron a la clínica de ESAS de 2011 a 2015. El ejercicio se centró en la idoneidad de la documentación basada en un sistema de puntuación desarrollado por los investigadores (50% fue adecuado según la valoración; los registros de la disposición de la paciente en el arbitraje, la fecha del incidente y la evidencia del tamizaje de la infección de transmisión sexual (ITS), fueron todos vitales a la hora de determinar la idoneidad). Se calcularon las estadísticas descriptivas e inferenciales. Resultados: La edad promedio de las participantes fue 14 años (rango intercuartil: 13-15). De 63.4% (78) con nacionalidad documentada, el 88.5% (69) fueron bahameñas y el 11.5% (9) haitianas. El estado de la documentación en término de las estadísticas no difirió significativamente por nacionalidad. Con respecto a la documentación, el 74% (91) registró el nombre de la escuela de la paciente, 59.3% (73) registró que la paciente conocía al agresor, y el 17.9% (22) indicó que la paciente no conocía al agresor, mientras que el 22.8% (28) no documentó esta última información. El tipo de penetración sexual fue indicado por 65.9% (81). De las variables vitales, 18.7% (23) registró la disposición de la paciente en el arbitraje, 29.8% (36) la fecha del incidente, y el 60.2% (74) evidencia del tamizaje de las ITS; 7.3% (9) documentó tres de ellas y 2.8% (28) dos. El porcentaje medio de documentación de las variables vitales fue 49.3% (± 3.6) para el Departamento de Accidentes y Emergencias (A&E), Hospital Princess Margaret, Nassau, frente al 30.5% (± 4.0) de las clínicas de salud pública (CSP) (p = 0.001). En general, el 69.9% (86 de 123) de los formularios de referencia se consideró inadecuado: 64.7% (33 de 51) del Departamento de A&E frente al 73.4% (47 de 64) de las CSP entre las 115 pacientes que proporcionaron la información de la remisión. Conclusión: Las deficiencias de la documentación de los formularios de remisión de abuso sexual exigen reformas. Se requiere una documentación completa y consistente.

Accuracy of Magnetic Resonance Arthrography in Detecting Rotator Cuff Tears / Precisión de la artrografía por resonancia magnética en la detección de desgarros del manguito rotador

ABSTRACT Objective: Shoulder pain, a common cause of productivity loss and health-related expense, is commonly due to rotator cuff tears. Magnetic resonance (MR) imaging with intra-articular gadolinium, MR arthrography, is accepted internationally as an excellent modality for evaluating the rotator cuff. Ultrasound is cheaper and only slightly less sensitive in detecting rotator cuff tears, but MR is superior in detecting ancillary lesions. Magnetic resonance arthrography was introduced at the University Hospital of the West Indies (UHWI), Jamaica, in July 2003. This study aimed to evaluate our experience with MR arthrography and assess its accuracy. Methods: A retrospective study was carried out. All MR arthrography cases performed at UHWI between July 2003 and July 2006 were reviewed. Medical records were reviewed to determine surgical correlation. Results: A total of 140 MR arthrograms were performed; 55% of the patients were female. Ages ranged from the second to the ninth decade, having a distribution approaching but not attaining a normal distribution (p = 0.03) with clustering in the middle years. Magnetic resonance arthrography demonstrated torn rotator cuffs in 40 patients, none of whom was under the age of 40 years (p < 0.001). Fifteen patients had surgery which confirmed torn rotator cuffs in all 15. Conclusion: Magnetic resonance arthrography was found to be accurate in detecting rotator cuff tears. It should be considered in the evaluation of patients with suspected rotator cuff tears. For patients under the age of 40 years, sonography could be used as an alternative.

RESUMEN Objetivo: El dolor en el hombro, el cual es causa común de pérdida de productividad y gastos relacionados con la salud, se debe comúnmente a desgarros del manguito rotador. La imagen por resonancia magnética (IRM) con gadolinio intra-articular - conocida como artrografía RM - se acepta internacionalmente como una excelente modalidad para evaluar el manguito rotador. El ultrasonido es más barato y sólo ligeramente menos sensible a la hora de detectar desgarros del manguito rotador, pero la RM es superior en la detección de lesiones secundarias. La artrografía por resonancia magnética se introdujo en el Hospital Universitario de West Indies (HUWI), Jamaica, en julio de 2003. Este estudio tuvo como objetivo evaluar nuestra experiencia con la artrografía RM y evaluar su precisión. Métodos: Se realizó un estudio retrospectivo. Se revisaron todos los casos de artrografías RM realizadas en HUWI entre julio de 2003 y julio de 2006. Se revisaron las historias clínicas a fin de determinar la correlación quirúrgica. Resultados: Un total de 140 artogramas RM fueron realizados. El 55% de los pacientes eran mujeres. Las edades variaron del segundo al noveno decenio, con una distribución que se acercaba pero no llevaba a alcanzar una distribución normal (p = 0.03), concentrándose en los años intermedios. La artrografía de resonancia magnética mostró desgarros de los manguitos rotadores en 40 pacientes, ninguno de los cuales tenía menos de 40 años (p < 0.001). Quince pacientes tuvieron cirugía que confirmaba desgarros de los manguitos rotadores en los 15. Conclusión: Se halló que la artrografía por resonancia magnética era exacta a la hora de detectar los desagarros del manguito rotador. Debe considerarse en la evaluación de pacientes con sospecha de desgarros del manguito rotador. Para los pacientes menores de 40 años de edad, la sonografía podría ser utilizada como alternativa.

Clinical audit of referrals for sexual abuse among females ages 13–19 years attending the Agape Family Medicine Clinic, Nassau, Bahamas, 2011–2015

OBJECTIVE: To evaluate the adequacy of the documentation of referrals for sexually abused females ages 13–19 years directed to the Agape Family Medicine Clinic for interim management. SUBJECTS AND METHODS: An approved review was performed on 123 referral forms regarding sexually abused females 13–19 years old who attended Agape’s Sexual Assault Follow-up and Evaluation (SAFE) clinic, Nassau, Bahamas. The exercise focussed on documentation adequacy based on a scoring system developed by the researchers: > 50% was assessed to be adequate, and recording disposition, date of incident and sexually transmitted infection (STI) screening was considered vital for adequacy. A current version of Statistical Package for the Social Sciences (IBM SPSS, v 21) generated descriptive and inferential statistics. RESULTS: Participants’ median age was 14 (IQR: 13, 15) years old. Of 63.4% (n = 78) with documented nationality, 88.5% (n = 69) were Bahamian and 11.5% (n = 9) Haitian. Documentation status did not differ statistically significantly by nationality. Regarding documentation, 74% (n =91) recorded school, 59.3% (n = 73) recorded knowing the assailant and 17.9% (n = 22) indicated not knowing. Approximately two-thirds (65.9%; n = 81) indicated penetration type; 18.7% recorded disposition, 29.8% (n =36) incident date and 60.2% STI screening; 7.3% (n = 9) documented all three and 22.8% (n = 28) two. Among public health clinics (PHCs), 45.3% (n = 29) did not indicate any of the three vital variables versus 7.8% (n = 4) for Accident and Emergency (A&E) referrals. Mean percent documentation for vital variables was 49.3 (± 3.6)%for A&E versus 30.5 (± 4.0)% for PHCs (p = 0.001). CONCLUSION: The deficient documentation status of referral forms demands the need for reform. Complete, consistent documentation is required.

Impact of the 'Providing Access to Continued Education' Programme on Repeat Teenage Pregnancy in the Bahamas.

OBJECTIVE: To determine the relationship of determinants such as age, ethnicity, education and sexual behaviour with repeat teenage pregnancy and to determine the impact of 'Providing Access to Continued Education' (PACE) programme in reducing repeat teenage pregnancy amongst its participants in The Bahamas. SUBJECTS AND METHODS: This retrospective cohort study included 397 attendees of the Adolescent Health Centre (AHC). Eighty-eight out of 139 registered participants completed the PACE programme. Data on age, ethnicity, education, sexual behaviour and repeat pregnancy in two years were analysed for descriptive statistics, and association of demographic characteristics and participation in the PACE programme with repeat pregnancy using the Chi-squared test. RESULTS: Mean age of participants was 16.4 ± 1.1 years; median school grade and mean grade point average (GPA) was 11 and 1.97 ± 0.7, respectively. The mean age at the first sexual activity was 14.9 ± 1.2 years. The mean age and number of sexual partners were 21 ± 4.3 years and 2 ± 1, respectively. Overall, repeat pregnancy rate was 39%: 37.4% amongst PACE registered and 31.8% amongst PACE completed mothers. No significant difference was observed in repeat pregnancy between registered and non-registered as well as those who completed the programme and those who did not. The odds ratio of 0.525 suggested that completion of the PACE programme had a moderate protective effect on reducing repeat pregnancy. CONCLUSIONS: Age, ethnicity, education and sexual behaviour showed no association with repeat pregnancy. The PACE programme did not reduce repeat pregnancy rate significantly. However, completion of the programme offered a moderate protection.

The Prevalence of Elevated Blood Pressure in Adolescents in Nassau, The Bahamas.

OBJECTIVE: To determine the prevalence of elevated blood pressure (EBP) in Bahamian adolescents. METHODS: A cross-sectional survey employing a self-administered questionnaire, and concurrently obtaining anthropometric measurements, was conducted involving selected grades 9, 10 and 11 students of all targeted public high schools in The Bahamas. RESULTS: The mean age of the 785 participants was 14.6 (± 1.153) years, and 87.6% were Bahamian. The prevalence of elevated systolic blood pressure (SBP) was 4.7% and 6.6% for elevated diastolic blood pressure (DBP). Elevated blood pressure prevalence was 8.9%. Elevated blood pressure was more common among grade 9 students (12-14-year olds) who had the largest proportion of EBP (55.7%). Both SBP and DBP increased with age in the males. Overall, students' prevalence of overweight/obesity was 32.2% (14.4% overweight, 17.8% obese). Body mass index (BMI), number of days per week eating fast food and perception of body weight were predictive of EBP. Body mass index, age and perception of body weight were found to be predictive of SBP (ßBMI = 0.25, p < 0.001; ßAge = 0.14, p < 0.001; ßWeight = 0.08, p < 0.037) and DBP (ßDBP = 0.192, p < 0.001). Overweight/obese students were 2.7 times more likely to have EBP. Elevated blood pressure was markedly associated with BMI, family history of hypertension and parents' overweight/obese status. CONCLUSION: The estimated prevalence of EBP in adolescent school children in New Providence, Bahamas, was comparable with neighbouring nations.

Association between obesity and impaired glucose tolerance in new providence adolescents as demonstrated by the HbA1c test / Asociación entre la obesidad y los trastornos de tolerancia a la glucosa entre los adolescentes de nueva providencia según lo demostrado por la prueba de HbA1c

OBJECTIVE: To explore the association between obesity and the development of impaired glucose tolerance (IGT) in Bahamian adolescents. METHODS: Eight hundred and seventy-three adolescents were randomly selected from five high schools in New Providence. Each student's weight, height, and waist and hip circumferences were recorded to determine body mass index (BMI). Individuals with BMIs above the 84th and 95th percentiles were classified as overweight and obese, respectively. Venous blood samples were collected from each subject and haemoglobin Ai c (HbAi c) levels were measured using a direct immunoassay method. The criterion established by the International Expert Committee for the diagnosis of IGT (HbA i c concentration of 6.0-6.4%) was used. An analysis of covariance was performed to evaluate the relationship between obesity and IGT, and a logistic regression analysis predicted the risk of IGT based on BMI classification. RESULTS: Of the 861 adolescents who completed the study, 15.0% were classified as overweight, 15.2% as obese and 7.9% as severely obese. The overall cumulative prevalence of IGT based on HbAi c levels was 16 100 cases per 100 000 adolescents and was greater in males than in females. Higher percentages of overweight and obese students were identified as having IGT compared with their normal-weight counterparts. An analysis of covariance with post hoc analyses revealed that severely obese males and females, respectively were almost 26 (OR = 25.54, 95%CI 9.92, 65.77) or 23 (OR = 22.96, 95% CI 9.81, 53.73) times more likely to develop IGT than their normal-weight counterparts (p < 0.005). CONCLUSION: The data show a strong positive association between IGT and obesity among Bahamian adolescents.

OBJETIVO: Explorar la asociación entre la obesidad y el desarrollo de trastornos de tolerancia a la glucosa (IGT) en los adolescentes de Bahamas. MÉTODOS: Ochocientos setenta y tres adolescentes fueron seleccionados aleatoriamente de cinco escuelas secundarias en Nueva Providencia. Se registraron peso, altura, y las circunferencias de cintura y cadera de cada estudiante, para determinar el índice de masa corporal (IMC). Las personas con IMC por encima de los percentiles 84 y 95 fueron clasificados como con sobrepeso y obesos, respectivamente. Se obtuvieron muestras de sangre venosa de cada sujeto, y se midieron los niveles de hemoglobina A 1c (HbAc utilizando un método de inmunoensayo directo. Se utilizó el criterio establecido por el Comité Internacional de expertos para el diagnóstico de IGT (concentración de HbA 1c de 6.0-6.4%). Se realizó un análisis de covarianza para evaluar la relación entre la obesidad y IGT, y un análisis de regresión logística para predecir el riesgo de IGT sobre la base de la clasificación del IMC. RESULTADOS: De los 861 adolescentes que completaron el estudio, 15.0% fueron clasificados como con sobrepeso, 15.2% como obesos, y 7.9% como extremadamente obesos. La prevalencia acumulativa general de IGT basada en los niveles de HbA 1c fue 16 100 casos por 100 000 adolescentes, y fue mayor en los varones que en las mujeres. Mayores porcentajes de estudiantes con sobrepeso y obesidad fueron identificados con IGT en comparación con sus contrapartes de peso normal. Un análisis de covarianza con análisis post-hoc reveló que los varones y hembras extremadamente obesos, respectivamente, fueron casi 26 (OR = 25.54, 95%CI 9.92, 65.77) o 23 (OR = 22.96, 95% CI 9.81, 53.73) veces más propensas a desarrollar IGT que sus contrapartes de peso normal (p < 0.05). CONCLUSIÓN: Los datos muestran una fuerte asociación positiva entre IGT y obesidad entre los adolescentes de las Bahamas.

A survey of patients with substance use disorders at government treatment facilities in The Bahamas / Estudio de pacientes con trastornos por uso de sustancias en centros gubernamentales de tratamiento en Las Bahamas

OBJECTIVE: To determine the sociodemographic information and characteristics of patients aged 18-60 years diagnosed with substance use disorders presenting to the three government treatment facilities. To determine the prevalence rates of alcohol, cannabis, cocaine and poly-substance use disorders in patients presenting to government treatment facilities. METHODS: The Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders fourth edition, text revision (DSM-IV-TR) Axis 1 disorders was the first instrument used to screen for drug abuse or dependence. Additional questionnaires included a sociodemographic questionnaire and the Survey of Addicted Patients in Treatment Centre Standardized Questionnaire. RESULTS: The number of participants interviewed in the study was 120 people; 89.2% were males and 10.8% were females. The mean age of all participants with substance use disorders was 36.22 (10.74) years and they were predominantly male (8 to 1). Males were mostly single, unemployed or casually employed, of middle school education and were residents of New Providence. Alcohol, cannabis and cocaine were the common drugs that were misused. Of cocaine users, 52 (82.5%) met the DSM-IV-TR criteria for dependence and of cannabis users, 20 (18.9%) met the DSM-IV-TR criteria for abuse. CONCLUSIONS: There is a need to conduct community surveys on school children, other adult populations eg in the wider community and on other island populations to determine the population rates of substance use disorders. Once the needs have been identified through research for the different islands and target groups, informed decisions can be made as to the allocation of financial and human resources.

OBJETIVO: Determinar la información sociodemográfica y las características de los pacientes en edades de 18-60 años diagnosticadas con trastornos por uso de sustancia, que acuden a los tres centros gubernamentales de tratamiento de la drogadicción. Determinar la tasa de prevalencia de los trastornos por uso de alcohol, cannabis, cocaína y polisustancias en los pacientes que acuden a los centros de tratamiento del gobierno. MÉTODOS: La Entrevista clínica estructurada para el diagnóstico y el Manual estadístico de trastornos mentales, cuarta edición, texto revisado (DSM-IV-TR), trastornos del eje 1, fue el primer instrumento utilizado para detectar el abuso o dependencia de drogas. Los cuestionarios adicionales incluyen un cuestionario sociodemográfico así como la llamada Encuesta de pacientes adictos en el cuestionario estandarizado de los centros de tratamiento. RESULTADOS: El número de participantes entrevistados en el estudio fue de 120 personas; 89.2% eran varones y 10,8% eran hembras. La edad promedio de todos los participantes con trastornos por uso de sustancias fue 36.22 (10,74) años y eran predominantemente masculinos (8 a 1). Los varones eran en su mayoría solteros, desempleados, o trabajadores eventuales, de nivel educacional medio, y residentes de Nueva Providencia. Alcohol, cannabis y cocaína fueron las comúnmente las sustancias del uso adictivo. De los consumidores de cocaína, 52 (82,5%) correspondían a los criterios del DSM-IV-TR con respecto a la dependencia, y de los consumidores de cannabis, 20 (18,9%) correspondían a los criterios de DSM-IV-TR en relación con el abuso de sustancias. CONCLUSIONES: Es necesario llevar a cabo encuestas comunitarias con niños en edad escolar, otras poblaciones adultas - por ejemplo en la comunidad en general y en otras poblaciones de la isla - para determinar las tasas poblacionales de trastornos por uso de sustancias. Una vez que las necesidades hayan sido identificadas mediante investigación de las diferentes islas y los grupos seleccionados como objetivos, pueden tomarse decisiones informadas en cuanto a la asignación de las finanzas y recursos humanos.

Severe sepsis in the emergency department: an observational cohort study from the university hospital of the West Indies / Sepsis severa en la sala de emergencias: un estudio observacional de cohorte en el hospital universitario de West Indies

OBJECTIVE: To describe the incidence, treatment and outcomes of patients with severe sepsis and septic shock in a setting where early goal directed therapy (EGDT) is not routinely performed. METHOD: An observational study of all adult patients admitted from the emergency department (ED) of the University Hospital of the West Indies (UHWI) with a diagnosis of severe sepsis and septic shock from July 5, 2007 to September 1, 2008 was conducted. Baseline parameters, treatment patterns and inhospital outcomes were evaluated. RESULTS: A total of 58 011 patients were seen and 762 (1.3%) had sepsis, 117 (15.4%) of whom were classified as severe sepsis or septic shock. Mean (SD) age was 59.2 (23.3) years and 49% were female. Medical history included hypertension (29%), diabetes mellitus (26%), stroke (8%), heart failure (6%) and HIV (6%). The most common sources of sepsis were pneumonia (67%) and urinary tract infection (46%). Median, interquartile range (IQR) time from triage to antibiotic administration was 126 (88, 220) minutes and antibiotics were given to 65.7% within three hours. Overall, organisms were sensitive to empirical antibiotics in 69%. Median (IQR) lactate was 5.3 (4.5, 7.5) mmol/L. Most patients (95%) were admitted to the ward; 1% went to the intensive care unit (ICU) and 2% died in the ED. Mean (SD) length of hospital stay was 9.5 (10.3) days. Inhospital mortality was 25% and survival correlated inversely with age (r pb = 0.25; p = 0.006). CONCLUSION: Despite a lack of EGDT, sepsis treatment patterns were consistent with "bestpractice" and mortality was lower than international comparators.

Association between Obesity and Impaired Glucose Tolerance in New Providence Adolescents as Demonstrated by the HbA1c Test.

OBJECTIVE: To explore the association between obesity and the development of impaired glucose tolerance (IGT) in Bahamian adolescents. METHODS: Eight hundred and seventy-three adolescents were randomly selected from five high schools in New Providence. Each student's weight, height, and waist and hip circumferences were recorded to determine body mass index (BMI). Individuals with BMIs above the 84th and 95th percentiles were classified as overweight and obese, respectively. Venous blood samples were collected from each subject and haemoglobin A1c (HbA1c) levels were measured using a direct immunoassay method. The criterion established by the International Expert Committee for the diagnosis of IGT (HbA1c concentration of 6.0-6.4%) was used. An analysis of covariance was performed to evaluate the relationship between obesity and IGT, and a logistic regression analysis predicted the risk of IGT based on BMI classification. RESULTS: Of the 861 adolescents who completed the study, 15.0% were classified as overweight, 15.2% as obese and 7.9% as severely obese. The overall cumulative prevalence of IGT based on HbA1c levels was 16 100 cases per 100 000 adolescents and was greater in males than in females. Higher percentages of overweight and obese students were identified as having IGT compared with their normal-weight counterparts. An analysis of covariance with post hoc analyses revealed that severely obese males and females, respectively were almost 26 (OR = 25.54, 95% CI 9.92, 65.77) or 23 (OR = 22.96,95% CI 9.81, 53.73) times more likely to develop IGT than their normal-weight counterparts (p < 0.05). CONCLUSION: The data show a strong positive association between IGT and obesity among Bahamian adolescents.

Colorectal anastomotic leakage at the university hospital of the west indies: an analysis of risk factors.

BACKGROUND: Anastomotic leakage remains a concern in general surgical practice. The significance lies in the resultant abdominal sepsis, related morbidity and mortality, risk of anastomotic loss, permanent stoma creation and the effect on local recurrence and overall patient survival in colorectal cancer cases. OBJECTIVES: This study serves to determine the leak rates and the mortality thereof related to colonic and rectal anastomoses at the University Hospital of the West Indies (UHWI) in Kingston, Jamaica. Independent factors contributing to anastomotic leaks in these patients will also be assessed and correlations determined. METHODS: A review of the medical records of one hundred and thirty-three cases of colonic and rectal anastomoses identified retrospectively over a three-year period provided relevant information for analysis. RESULTS: Anastomotic leaks were identified in twelve patients, providing a leak rate of 9.0%. No 30-day mortality related to anastomotic leakage was noted. Based on a multivariate analysis, male gender was identified as the sole independent factor related to anastomotic leakage. CONCLUSION: Colorectal anastomotic leak rates at UHWI fell at the upper limit of leak rates typically quoted in the literature. No modifiable risk factor appeared to contribute to this leak rate. Early identification and intervention is critical in limiting mortality associated with colorectal anastomotic leakage.

HIV/AIDS knowledge and sexual behaviour among junior high school students in New Providence, Bahamas.

OBJECTIVE: To determine accuracy of knowledge and sexual behaviour patterns of junior high school students in New Providence towards HIV/AIDS and identify gender variations. METHODS: A cross-sectional study with cluster sampling of classrooms was undertaken at two schools utilizing a questionnaire. SPSS was used for statistical analysis. RESULTS: Three hundred and fifty-four students participated in the study; the mean age was 12.25 years, 55.1% males and 44.9% females. Most (88%) students identified sexual intercourse as a mode of HIV transmission, 62.5% were accurate regarding anal sex and 32.9% were accurate about sexual intercourse in the water, as modes of HIV transmission. Abstinence was identified as a method of HIV prevention by 54.1% of students although 85.2% of students knew that condoms were a method of prevention. On beliefs regarding transmission, 21.2% believed mosquito bites and 13.1% believed toilet seats were routes for disease spread. Only 16.9% of participants reported a history of sexual intercourse; of those, 57.6% indicated that they were age ≤ 10 years when they first had intercourse. Concerning use of birth control, 64.5% of sexually experienced respondents reported never using any method. CONCLUSION: Junior high school students have fairly accurate knowledge of HIV/AIDS but misconceptions regarding transmission are still prevalent; patterns in gender variation are few.

Chronic regulation of colonic epithelial secretory function by activation of G protein-coupled receptors.

BACKGROUND: Enteric neurotransmitters that act at G protein-coupled receptors (GPCRs) are well known to acutely promote epithelial Cl(-) and fluid secretion. Here we examined if acute GPCR activation might have more long-term consequences for epithelial secretory function. METHODS: Cl(-) secretion was measured as changes in short-circuit current across voltage-clamped T(84) colonic epithelial cells. Protein expression was measured by western blotting and intracellular Ca(2+) levels by Fura-2 fluorescence. KEY RESULTS: While acute (15 min) treatment of T(84) cells with a cholinergic G(q) PCR agonist, carbachol (CCh), rapidly stimulated Cl(-) secretion, subsequent CCh-induced responses were attenuated in a biphasic manner. The first phase was transient and resolved within 6 h but this was followed by a chronic phase of attenuated responsiveness that was sustained up to 48 h. CCh-pretreatment did not chronically alter responses to another G(q)PCR agonist, histamine, or to thapsigargin or forskolin which elevate intracellular Ca(2+) and cAMP, respectively. This chronically acting antisecretory mechanism is not shared by neurotransmitters that activate G(s)PCRs. Conditioned medium from CCh-pretreated cells mimicked its chronic antisecretory actions, suggesting involvement of an epithelial-derived soluble factor but further experimentation ruled out the involvement of epidermal growth factor receptor ligands. Acute CCh exposure did not chronically alter surface expression of muscarinic M(3) receptors but inhibited intracellular Ca(2+) mobilization upon subsequent agonist challenge. CONCLUSIONS & INFERENCES: These data reveal a novel, chronically acting, antisecretory mechanism that downregulates epithelial secretory capacity upon repeated G(q)PCR agonist exposure. This mechanism involves release of a soluble factor that uncouples receptor activation from downstream prosecretory signals.

Propofol sedation in patients undergoing colonoscopy in Jamaica.

BACKGROUND: Propofol sedation is increasingly used for colonoscopy and may be associated with increased satisfaction and efficiency in diagnostic and therapeutic endoscopy. However propofol has a relatively narrow therapeutic window as it frequently produces deep sedation, and can precipitate respiratory depression. AIM: To determine the efficacy, safety and patient satisfaction with propofol sedation in patients undergoing colonoscopy at the University Hospital of the West Indies (UHWI). METHODS: Patients undergoing outpatient colonoscopy at the UHWI who were sedated with propofol were studied. Boluses of 10 - 20 mg of propofol at intervals of 2 - 5 minutes, as needed for adequate sedation, were administered after initial induction. Continuous monitoring of the pulse rate, and oxygen saturation were performed and the blood pressure checked every 2 - 5 minutes. All patients received supplemental oxygen (4 L/min). The following observations were recorded: the endoscopist recorded the ease of the procedure, the anaesthetist recorded the comfort of the patient throughout the procedure and at the time of discharge, and the patient stated the degree of satisfaction with the procedure. Any unusual events were recorded. RESULTS: Sixty consecutive patients sedated with propofol were studied. There were 28 (46.7%) males, with a mean age of 58.3 years and 32 (53.3%) females, with mean age of 59.5 years. Most were normal healthy patients (56.6%). Comorbid illnesses were present in 43.4%, with hypertension being most common (23.3%). All patients were classified as ASA class 1 and 2. The average dose of propofol used was 180 mg (range 50 - 355 mg). The mean duration of colonoscopy was 19.5 minutes. The mean recovery period (able to stand) was 29.6 minutes. There were no documented cases of significant hypotension, bradycardia, or hypoxaemia during the procedure. Transient apnoeic episodes during the initial stages of sedation occurred in 12 (20%) patients. The majority of patients (91.7%) rated the experience as being extremely good or excellent. The majority could not recall the actual colonoscopy and there were minimal subjective reports of nausea or discomfort during the procedure. CONCLUSIONS: Propofol sedation was associated with quick recovery and excellent satisfaction by patients and is a suitable alternative for sedation for colonoscopy in Jamaica.

Commonly used botanicals and vitamins and their impact on blood pressure and blood loss in surgical gynaecology patients.

We wanted to determine botanical and vitamin use in surgical gynaecology patients at UHWI and their effects on blood pressure and blood loss. The study was prospective and observational. Before elective surgery, we evaluated 133 patients on the use of botanicals and vitamins. We measured pre- and intraoperative blood pressure and intraoperative blood loss to determine any association with botanical use. Botanicals were used by 68.4% of patients with a 45.1% use within 2 weeks before surgery, p = 0.002). Users were older (p = 0.024) and had more chronic illnesses (p = 0.003). They also had higher mean preoperative diastolic blood pressure (p = 0.016) but no statistically significant difference in intraoperative blood pressures. Blood loss was greater with recent use of certain anticoagulant botanicals. We conclude that the use of certain botanicals may increase blood pressure or increase surgical bleeding and patients and doctors should be aware of their risk.

Knowledge and practice of occupational infection control among healthcare workers in Jamaica.

OBJECTIVE: To assess the knowledge, compliance and practice among healthcare workers of occupational infection control at two hospitals in Jamaica. METHODS: Employing a cross-sectional study design, medical personnel (physicians and nurses) at two hospitals in Jamaica, were studied, utilizing a structured questionnaire consisting of 14 items to collect the data. RESULTS: Participants considered the following fluids, not blood stained, high risk for HIV transmission: breast milk (79%), saliva (14%), urine (27%), pleural fluid (53%), CSF (55%), synovial fluid (37%), faeces (27%), peritoneal fluid (53%) and vomitus (21%). The respondents estimated the risk of transmission of infection after a needlestick injury from a patient with: HIV, mean 22.5%, HB, 34% and HCV, 26%. Needles for drawing blood were identified as having the highest risk for transmission of infections in 63%. The following precautions were adhered to all the time: wearing gloves (38%), not re-sheathing needles (22%), not passing needles directly to others (70%), properly disposing of sharps (86%) and regarding patients' blood and other high risk fluid as potentially infected (62%). Post exposure, 43% indicated bleeding/squeezing the NSI site as the initial first-aid procedure, washing with soap and water (29%) and irrigating the area with water (20%). CONCLUSIONS: Healthcare workers are aware of the risk of transmission of infection, however compliance with universal precautions was inadequate. An improvement in knowledge and practice with clear guidelines are needed and a comprehensive programme to educate HCWs regarding compliance with universal precautions is urgently required.

Prevalence of needlestick injuries and other high risk exposures among healthcare workers in Jamaica.

OBJECTIVE: To assess the prevalence of needlestick injuries (NSIs) and other high risk exposures among healthcare workers at two hospitals in Jamaica. METHODS: Employing a cross-sectional study design, medical personnel (physicians, nurses) at two hospitals in Jamaica, were studied, utilizing a structured questionnaire consisting of 14 items to collect data on needle stick injuries and other injuries. RESULTS: There were 67 needlestick injuries in 47 persons. Of those sustaining an injury, 52% of physicians and 40% of nurses had NSIs. Re-capping needles accounted for 21% of injuries, various minor procedures, 21%, injury during surgery, 19.4% and taking blood, 12%. In those sustaining NSIs, 47% were reported and 26% of reported cases received counselling. Appropriate blood tests were performed on 34% and post-exposure prophylaxis (PEP) for HIV was administered to 30%. Hollow bore needles caused 47.8% of injuries, 25.4% occurred with suture needles and 19.4% with intravenous branulas. Other occupational exposure was reported by 31%, including blood on hands and other body parts 39%, blood to face and eyes, 18%, splashed with liquor, 18%, splashed with bloody fluid, 11% and contact with vomitus and urine in eye, 4%. CONCLUSION: Needlestick injuries and other high risk exposures were high; incident reporting and post exposure management were inadequate. A comprehensive programme to address factors that contribute to the occurrence of NSIs and other occupational exposures is urgently needed.

Dynamics of antibiotic usage in the intensive care unit at the University Hospital of the West Indies.

OBJECTIVE: To determine antibiotic usage patterns in the Intensive Care Unit (ICU) at the University Hospital of the West Indies (UHWI). METHOD: A cross-sectional, analytical study of consecutive patients admitted to the ICU was conducted between July and December 2007. Exclusion criteria were HIV-positive patients, patients < 12 years and those discharged or who died within 48 hours of admission. Data were collected from medical records, stored and analysed using the SPSS Version 12. RESULTS: Of the 150 eligible patients, 109 had complete data (73%). Mean age was 50.8 +/- 20.7 years, with mean APACHE II score of 15.6 +/- 6.7. Forty-five patients (41.3%) received prophylactic antibiotics, most commonly ceftriaxone (31.7%) and metronidazole (19.0%). Appropriate discontinuation within 24 hours occurred in only 11.1%. Two-thirds of patients (67.9%) were treated with empiric antibiotics, most commonly piperacillin/tazobactam (32.1%), ceftazidime (27.5%) or metronidazole (27.5%). Reasons for empiric choice were primarily coverage of organisms based on presumed source of sepsis (45.6%), and broad spectrum, high-powered coverage (23.5%). Courses ranged from 1 - 42 days and were adequate based on subsequent cultures in 71% of cases. Culture reports took between 2 - 8 days with a mean of 3.7 days to become available. De-escalation was practised in only 2 of 26 (7.7%) cases and intravenous to oral switch therapy in only 3.3%. Thirty-two (29.4%) patients died, with sepsis being a cause in 12 (37.5%). CONCLUSIONS: Improved attention to discontinuation of prophylactic antibiotics, appropriate duration of antibiotic courses and de-escalation are essential if the antibiotic practices in the ICU at the UHWI are to compare favourably with international recommendations.

Febrile neutropaenia in cancer patients.

BACKGROUNDS: Febrile neutropaenia is a common complication of chemotherapy in cancer patients. Empirical antibiotic regimes are based on the epidemiological characteristics of bacterial isolates globally and locally. METHOD: This study retrospectively reviewed all cases of febrile neutropaenia in patients with confirmed cancer admitted at the University Hospital of the West Indies in the four-year period between, January 1, 2003 and December 31, 2006 and who received chemotherapy. Cases were identified from blood culture records and hospital charts which were reviewed to determine the aetiological agents causing bacteraemia, their antimicrobial susceptibilities and clinicalfeatures. These cases were compared with non-neutropaenic cancer patients admitted with fever. RESULTS: A total of 197 febrile episodes in cancer patients were reviewed. Thirty-seven per cent had febrile neutropaenia while 62% were non-neutropaenic. Acute myeloid leukaemia was the most common haematological malignancy and the most common solid tumour was breast cancer. Twenty-six per cent of patients had a positive blood culture. In febrile neutropaenic patients, Escherichia coli was the most common organism isolated followed by coagulase-negative staphylococci while in non-neutropaenic patients, coagulase-negative staphylococci was most common. Acinetobacter infections was prominent in non-neutropaenic patients but absent in neutropaenic patients. More than one organism was cultured in 9 neutropaenic and 18 non-neutropaenic patients. Mortality was 10.8% in neutropaenic and 24.4% in non-neutropaenic patients. CONCLUSION: Gram-negative organisms are the predominant isolates in febrile neutropaenic episodes in this cohort of patients. Non-neutropaenic patients had an increased mortality with an increase in Acinetobacter infections and multiple isolates.
