Reprocessamento de Marca-Passos em Países de Língua Portuguesa: Uma Reflexão Clínica / Pacemaker Reuse in Portuguese Speaking Countries: A Clinical Reflection

Resumo Há uma enorme disparidade entre os países de alta renda e outros em termos de acesso a dispositivos médicos cardíacos, como marca-passos e desfibriladores implantáveis. Os custos são uma das principais barreiras ao uso de dispositivos cardíacos nesses países. Existem iniciativas internacionais que visam reduzir essa disparidade, e o reuso de marca-passos tem sido discutido como uma possível alternativa. O conceito de reutilização de marca-passos não é novo; entretanto, estudos recentes têm se mostrado seguros, éticos e eficazes para aqueles que precisam de dispositivos eletrônicos cardíacos implantáveis e não tem como adquiri-los. Parte dos países de língua portuguesa, especialmente na África, precisam de uma resposta imediata que beneficie seus inúmeros pacientes que sofrem de arritmias tratáveis.

Abstract There is a gap between high-income countries and others in terms of access to medical cardiac devices, such as pacemakers and implantable cardioverter defibrillators. Costs are one of the main barriers to the use of cardiac devices in these countries. There are international initiatives that aim to reduce the gap. The reuse of pacemakers has been discussed as a possible alternative to this problem. The concept of reusing pacemakers is not new; however, recent studies have proven to be safe, ethical, and effective for those who need cardiac implantable electronic devices and cannot afford them. Part of the Portuguese-speaking countries, especially in Africa, need an immediate response that benefits their countless patients who suffer from treatable arrhythmias.

Early Life Body Size in Relation to First Intracerebral or Subarachnoid Hemorrhage / 대한뇌졸중학회지

BACKGROUND AND PURPOSE: As risk of hemorrhagic stroke may have early life origins, we investigated associations of birth weight and childhood body mass index (BMI) with adult intracerebral hemorrhage (ICH) or subarachnoid hemorrhage (SAH). METHODS: We included 240,234 Danish schoolchildren, born 1936 to 1989, with information on birth weight and measured weights and heights from 7 to 13 years. We calculated hazard ratios (HRs) and confidence intervals (CIs) for the associations between early life anthropometrics and ICH or SAH, identified through linkage with national registers. RESULTS: During the study period, 1,947 individuals (39% women) experienced an ICH and 797 individuals (64% women) experienced a SAH. Per 500 g increase in birth weight, women had a 10% decreased risk of SAH (HR, 0.90; 95% CI, 0.83 to 0.97) and men had a 10% decreased risk of ICH (HR, 0.90; 95% CI, 0.85 to 0.95). Birth weight was not associated with risks of ICH in women or SAH in men. In men, a childhood BMI below average (BMI z-score < 0) was associated with increased risks of ICH. The association was stronger at older childhood ages, and at 13 years a BMI z-score of –1 was associated with a HR of 1.17 (95% CI, 1.06 to 1.28), and a BMI z-score of –2 with a HR of 1.46 (95% CI, 1.17 to 1.82) for ICH. Childhood BMI was not associated with risks of ICH in women or with risks of SAH in both sexes. CONCLUSIONS: Early life body size is associated with ICH and SAH, and the associations differ by sex.

Radiation-Induced Giant Cell Granuloma Mimicking Relapsed Hodgkin Lymphoma at FDG-PET/CT / 대한핵의학회잡지

A 22-year-old woman was diagnosed with intermediate risk stage II Hodgkin lymphoma and treated with three cycles of adriamycin, bleomycin, vinblastine, and dacarbazine (ABVD) followed by involved-field radiation therapy. A complete metabolic remission was achieved after two cycles of ABVD, which was maintained until three years after completion of treatment. Follow-up FDG-PET/CT four years after completion of treatment, however, showed a new FDG-avid (Deauville score of 4) lesion in the right scapula, suggesting relapsed disease. Computer tomography (CT)-guided biopsy of this lesion was performed and subsequent histological examination revealed a radiation-induced giant cell granuloma.

Classical natural ovine scrapie prions detected in practical volumes of blood by lamb and transgenic mouse bioassays

Scrapie is diagnosed antemortem in sheep by detecting misfolded isoforms of prion protein (PrP(Sc)) in lymphoid follicles of the rectal mucosa and nictitating membranes. Assay sensitivity is limited if (a) the biopsy is collected early during disease development, (b) an insufficient number of follicles is collected, or (c) peripheral accumulation of PrP(Sc) is reduced or delayed. A blood test would be convenient for mass live animal scrapie testing. Currently approved techniques, however, have their own detection limits. Novel detection methods may soon offer a non-animal-based, rapid platform with detection sensitivities that rival the prion bioassay. In anticipation, we sought to determine if diseased animals could be routinely identified with a bioassay using B lymphocytes isolated from blood sample volumes commonly collected for diagnostic purposes in small ruminants. Scrapie transmission was detected in five of six recipient lambs intravenously transfused with B lymphocytes isolated from 5~10 mL of blood from a naturally scrapie-infected sheep. Additionally, scrapie transmission was observed in 18 ovinized transgenic Tg338 mice intracerebrally inoculated with B lymphocytes isolated from 5~10 mL of blood from two naturally scrapie-infected sheep. Based on our findings, we anticipate that these blood sample volumes should be of diagnostic value.

Integration of robotics into two established programs of minimally invasive surgery for endometrial cancer appears to decrease surgical complications / 부인종양

OBJECTIVE: To compare peri- and postoperative outcomes and complications of laparoscopic vs. robotic-assisted surgical staging for women with endometrial cancer at two established academic institutions. METHODS: Retrospective chart review of all women that underwent total hysterectomy with pelvic and para-aortic lymphadenectomy by robotic-assisted or laparoscopic approach over a four-year period by three surgeons at two academic institutions. Intraoperative and postoperative complications were measured. Secondary outcomes included operative time, blood loss, transfusion rate, number of lymph nodes retrieved, length of hospital stay and need for re-operation or re-admission. RESULTS: Four hundred and thirty-two cases were identified: 187 patients with robotic-assisted and 245 with laparoscopic staging. Both groups were statistically comparable in baseline characteristics. The overall rate of intraoperative complications was similar in both groups (1.6% vs. 2.9%, p=0.525) but the rate of urinary tract injuries was statistically higher in the laparoscopic group (2.9% vs. 0%, p=0.020). Patients in the robotic group had shorter hospital stay (1.96 days vs. 2.45 days, p=0.016) but an average 57 minutes longer surgery than the laparoscopic group (218 vs. 161 minutes, p=0.0001). There was less conversion rate (0.5% vs. 4.1%; relative risk, 0.21; 95% confidence interval, 0.03 to 1.34; p=0.027) and estimated blood loss in the robotic than in the laparoscopic group (187 mL vs. 110 mL, p=0.0001). There were no significant differences in blood transfusion rate, number of lymph nodes retrieved, re-operation or re-admission between the two groups. CONCLUSION: Robotic-assisted surgery is an acceptable alternative to laparoscopy for staging of endometrial cancer and, in selected patients, it appears to have lower risk of urinary tract injury.

HIV/AIDS: perceptions of the Grenadian faith-based community / VIH/SIDA: percepciones de la comunidad de fe Granadina

OBJECTIVE: This exploratory study conducted in 2008 aimed at gathering the views and opinions of leaders of the faith-based community (FBC) in Grenada about the increased incidence of HIV/AIDS in the Caribbean region including their beliefs and attitudes towards persons living with HIV/AIDS (PLHIV/AIDS). DESIGN AND METHODS: The study followed a cross-sectional design and used a qualitative approach. Telephone surveys were conducted with all faith-based organizations and semi-structured interviews done with key leaders representing the faith-based community in Grenada. RESULTS: Findings showed that perceptions of HIV/AIDS are embedded in a socio-political-cultural context where many risk behaviours and factors intertwine in complex ways. Religious beliefs are based on love, compassion and acceptance. The most prominent risk behaviours associated with the spread of HIV/AIDS identified by leaders are homosexuality, prostitution, promiscuity and substance abuse which are in direct contradiction to their beliefs and teachings. Leaders felt that these risk behaviours were exacerbated by changes in family structure and the absence of a common moral discourse shared by all sectors of society. CONCLUSION: The faith-based community has a significant presence across Grenada and it can be an effective partner in helping communities understand and prevent HIV/AIDS and overcome the stigma and discrimination associated with this disease. Training and effective strategies are needed to engage them in the national response to HIV/AIDS without threatening their ideologies and practices.

OBJETIVO: Este estudio exploratorio realizado en 2008 tuvo por objetivo recoger los puntos de vistas y opiniones de líderes de la comunidad de fe en Granada, acerca del aumento de la incidencia de VIH/SIDA en la región caribena, incluyendo sus creencias y actitudes hacia personas que viven con VIH/SIDA (PLVIH/SIDA). DISEÑO Y MÉTODOS: El estudio tuvo por base un diseno transversal y un enfoque cualitativo. Se llevaron a cabo encuestas telefónicas con todas las organizaciones de fe y se realizaron entrevistas semiestructuradas a líderes importantes, representantes de la comunidad defe en Granada. RESULTADOS: Los hallazgos mostraron que las percepciones del VIH/SIDA se hallan embebidas en un contexto socio-político-cultural en el que múltiples comportamientos y factores de riesgo se entrelazan deformas complejas. Las creencias religiosas se basan en el amor, la compasión y la aceptación. Los comportamientos de riesgo más sobresalientes asociados con la diseminación del VIH/SIDA, identificados por los líderes fueron la homosexualidad, la prostitución, la promiscuidad, y el abuso de substancias que están en la contradicción directa con sus creencias y ensenanzas. Los líderes sentían que estas conductas de riesgo se hallaban exacerbadas por los cambios en la estructura de la familia y la ausencia de un discurso moral común compartido por todos los sectores de la sociedad. CONCLUSIÓN: La comunidad de fe tiene una presencia significativa en toda Granada y puede ser un aliado eficaz a la hora de ayudar a las comunidades a entender y prevenir el VIH/SIDA, así como a superar el estigma y la discriminación asociados con esta enfermedad. Se necesitan entrenamiento y estrategias efectivas para comprometer a las comunidades de fe a una respuesta nacional frente al VIH/SIDA, sin amenazar sus prácticas e ideologías.

A survey of physicians' knowledge and attitudes regarding antimicrobial resistance and antibiotic prescribing practices at the University Hospital of the West Indies / Un estudio sobre los conocimientos y actitudes de los médicos en relación con la resistencia antimicrobiana y la práctica de prescripción de antibióticos en el Hospital Universitario de West Indies

OBJECTIVE: To identify physicians' knowledge and attitudes regarding antimicrobial resistance and antibiotic prescribing practices at the University Hospital of the West Indies (UHWI). METHODS: A cross-sectional survey of physicians at the UHWI was conducted between September 2008 and April 2009 using a 28-item, self-administered questionnaire. Eligible physicians from several specialities were identified from departmental rotas. RESULTS: A total of 174 physicians completed the questionnaire, a response rate of 73%. Most physicians considered antibiotic resistance to be an extremely important global problem (55%) but less significant nationally (35%). Factors identified as important in producing resistance included wide-spread use of antibiotics (91%), inappropriate empiric choices (79%) and use of broad-spectrum agents (70%). Hand-washing was not considered to be important in reducing resistance. Useful interventions included access to current information on local resistance patterns (90%), institutional specific antibiotic guidelines (89%) and educational programmes (89%). Antibiotic cycling (40%) and restriction (35%) were regarded as less helpful. Knowledge of resistance-prone antibiotics and specific resistant organisms at the UHWI was poor, except for methicillin-resistant Staphylococcus aureus (MRSA). Empiric therapy for common infections was appropriate in most cases, and antibiotic choices were guided by availability of drugs (89%) and patient factors such as renal disease or allergy (80%). Only 45% of physicians would de-escalate to a narrow-spectrum antibiotic guided by a microbiology report, and consultants were more likely to de-escalate therapy than junior staff (p = 0.002). CONCLUSIONS: Although physicians were aware of the problem of resistance to antibiotics and the contributory factors, their practice did not reflect measures to reduce it. Continuing educational programmes and institution-specific antibiotic prescribing guidelines are needed.

OBJETIVO: Identificar los conocimientos y actitudes de los médicos con respecto a la resistencia antimicrobiana y la práctica de prescripción de antibióticos en el Hospital Universitario de West Indies (UHWI). MÉTODOS: Se llevó a cabo un estudio transversal en UHWI, entre septiembre del 2008 y abril del 2009 de abril, usando un cuestionario autoadministrado de 28 puntos. Los médicos elegibles de varias especialidades fueron identificados de las listas departamentales. RESULTADOS: Un total de 174 médicos completaron el cuestionario, para una tasa de respuesta del 73%. La mayor parte de los médicos consideró que la resistencia antibiótica constituye un problema sumamente importante desde un punto de vista global (55%) pero menos significativo desde una perspectiva nacional (35%). Los factores identificados como importantes en la formación de la resistencia incluyeron el uso generalizado de antibióticos (91%), las elecciones empíricas inapropiadas (79%), y el uso de agentes de amplio espectro (70%). El lavarse las manos no se consideró importante para la reducción de la resistencia. Las intervenciones útiles incluyeron el acceso a la información corriente sobre patrones de resistencia locales (90%), normas institucionales específicas sobre el uso de antibióticos (89%) y programas educativos (89%). El ciclo (40%) y la restricción (35%) de los antibióticos se consideraron menos útiles. El conocimiento de antibióticos con tendencia a la resistencia y organismos resistentes específicos en el HUWI era pobre, excepto en el caso del Staphylococcus aureus resistente a la meticilina (SARM). La terapia empírica para las infecciones comunes fue apropiada en la mayoría de los casos, y las opciones antibióticas estuvieron dictadas por la disponibilidad de medicamentos (89%) y factores relacionados con los pacientes, tales como enfermedades renales o alergias (80%). Sólo el 45% de los médicos desescalarían a un antibiótico de estrecho espectro guiado por un informe microbiológico, y los consultantes mostraron una tendencia mayor a desescalar la terapia, en comparación con la observada en el personal subalterno (p = 0.002). CONCLUSIONES: Aunque los médicos tenían conciencia del problema de la resistencia a los antibióticos y los factores contribuyentes, su práctica no reflejó las medidas para reducirla. Se necesitan programas de educación continua y normas institucionales específicas para la prescripción de antibióticos.

Health Risk Behaviors of High School Learners and their Perceptions of Preventive Services offered by General Practitioners

"Background: Adolescence spans nearly a decade in which young people may initiate health risk behaviors like unsafe sexual practices and alcohol; tobacco and other drugs use (ATOD use). Most adolescent mortality and morbidity; attributable to such health risk behaviors; are preventable. Managing the consequences of health risk behaviors is costly and does not reduce the number of young people initiating these unhealthy lifestyle choices. The emphasis needs to shift towards the provision of adolescent primary and secondary preventive services. Overseas efforts involve national health risk behavior screening; the application of national guidelines for primary health care workers in all contexts and continuing evaluation so that appropriate region specific policies can be instituted. With the completion of our second South African National Health Risk Behavior survey and the implementation and evaluation of the National Adolescent Friendly Clinic Initiative in government clinics; we lack national guidelines for the primary health care worker to administer adolescent preventive services. Furthermore; the NAFCI initiative does not involve the general practitioner in the private sector. The aim of the research is to assess how the economically disadvantaged youth from public schools access the private sector general practitioner for preventive services related to health risk behaviors. Methods: This cross-sectional descriptive study was conducted among senior high school learners (Grades 10; 11 and 12) from 18 randomly selected secondary public; co-educa -tional schools with an ordinary curriculum in the Johannesburg educational districts; during the first three school terms of 2002. A self administered research questionnaire was used to ascertain learners self reported involvement in health risk behaviors and their interaction with their GP in dealing with these health risk behaviors. Results: 1139 learners completed the research questionnaires. 1. Learners reported a high prevalence of health risk behaviors: 65for alcohol use; 57for sexual activity; 39for tobacco use and 15for drug use. 2. The predominant pattern of substance use was the experimental pattern of having tried these substances: 40for cigarette use; 53for alcohol use; 54for injected drug use and 57for other drug use. The majority of sexually active adolescents were practicing unsafe sex (55had multiple partners; 52without condoms and 28without family planning). 3. Learners reported a high prevalence of coexisting health risk behaviors: 44for alcohol use and sexual activity; 36for tobacco and alcohol use and 26for tobacco use and sexual activity. 4. Risk perception was lower for sexual activity (25felt in danger and 5felt affected) than for substance use (an average of 82felt in danger and 40felt affected). Of the 1139 learners; only 271 learners (24) had a GP in private practice. 1. The adolescent-GP interaction was favorable for preventive service delivery: 70of learners had medical aid cover; 41were seeing their GP for more than five years; 92were the ""family?? doctor; 80had visited their GP in the past 6 months and 60had consulted on their own at least once. 2. Primary preventive service delivery to those not involved in health risk behaviors was poor: 28for sexual activity; 24for drug use; 23for alcohol use and 19for tobacco use. 3. Uncovering of health risk behaviors occurred to varying degrees: 40for sexual activity; 18with alcohol use; 18with tobacco use and 11with drug use. 4. Secondary preventive service delivery to those involved in health risk behaviors was better: averages of 89for sexual activity; 84for drug use; 54for tobacco use and 38for alcohol use. Statistically significant learner and general practitioner demographics highlighted the complex dynamics involved in this interaction. Conclusions: The study showed that adolescents from economically disadvantaged backgrounds have a high prevalence of health risk behaviors but utilize the general practice resource to a limited degree. Despite the interaction between adolescent and general practitioner being conducive to the receipt of primary and secondary preventive services; this was not optimal"

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.

Bilateral metastasis to the retina, choroids and optic nerve from breast cancer: a clinicopathological case.

A 39-year-old Asian woman, with a known history of breast cancer, presented with a gradual onset of painless reduction in vision in both eyes. Examination revealed visual acuity of counting fingers in the right eye and light perception in the left. There were subretinal lesions in the posterior poles of both eyes and retinal detachment in the left eye. Later she developed left proptosis and restriction in left ocular movement, most likely to be caused by metastatic extraocular spread. She subsequently died from disseminated metastatic disease. Histopathological examination confirmed tumor cells infiltrating the choroids, retina and optic nerve in both eyes. The tumor cells were arranged in lobular fashion and stained positively with Periodic Acid Schiff, suggesting the primary to be lobular adenocarcinoma type. Choroidal metastatic disease is common but bilateral retinal and optic nerve involvement with extraocular spread from breast cancer is rare.

The control of hypertension by use of coconut water and mauby: two tropical food drinks / El Control de la Hipertensión Mediante el uso del Agua de Coco y el Mauby: Dos Bedidas Tropicales Naturales

In this study, the authors investigated the effect of regular consumption of two tropical food drinks, coconut (Cocos nucifera) water and mauby (Colubrina arborescens), on the control of hypertension. Twenty-eight hypertensive subjects were assigned to four equal groups and their systolic and diastolic blood pressures recorded for two weeks before and then for another two weeks while receiving one of four interventions. One group (the control) received bottled drinking water, the second group received coconut water, the third received mauby and the fourth group, a mixture of coconut water and mauby. Significant decreases in the mean systolic blood pressure were observed for 71, 40 and 43 respectively of the groups receiving the coconut water, mauby and the mixture (p < or = 0.05). For these groups, the respective proportions showing significant decreases in the mean diastolic pressure were 29, 40 and 57. For the group receiving the mixture, the largest decreases in mean systolic and mean diastolic pressure were 24 mmHg and 15 mmHg respectively; these were approximately double the largest values seen with the single interventions

En el presente estudio, los autores investigaron el efecto del consume regular de dos bebidas tropicales naturales: el agua de coco (Cocos nucifera) y el mauby (Colubrina arborescens) sobre el control de la hipertensión. A veintiocho sujetos hipertensos asignados a cuatro grupos iguales, se les hizo un registro de su presión sanguínea sistólica y diastólica por espacio de dos semanas antes, y luego otras dos semanas mientras que recibían una de cuatro intervenciones. Un grupo (de control) recibió agua mineral embotellada; un segundo grupo recibió agua de coco; un tercer grupo recibió mauby; y finalmente el cuarto grupo recibió una bebida mixta de agua de coco y mauby. Se observaron disminuciones significativas de la presión sistólica media en el 71%, el 40% y el 43% respectivamente, de los grupos que recibieron el agua de coco, el mauby, y la bebida combinada (p ≤ 0.05). Para estos grupos, las proporciones respectivas que mostraron disminuciones significativas de la presión diastólica media fueron 29%, 40% y 57%. Para el grupo que recibió la bebida mixta, las disminuciones mayores en las presiones medias sistólica y diastólica fueron 24 mmHg y 15 mmHg respectivamente - aproximadamente el doble de los valores observados en cada una de las intervenciones.

Cough and fear of sleep: early clinical signs of Bordetella pertussis in an adult

Pertussis is increasing in frequency among adults, but early diagnosis requires special attention to details in the medical history. We describe a 64 year-old male with classic signs and symptoms of pertussis and documented Bordetella pertussis infection that were overlooked because he presented with a chief complaint of cough and fear of falling asleep. Coughing paroxysms and a feeling of suffocation (30-60 seconds) only occurred at night after short periods of deep sleep (30-45 minutes). The physicians did not observe these episodes during daytime examinations, and the basis of the patient's fear of sleep was not explored. We recommend reassessment of how adults describe symptoms of pertussis, including fear of sleep, and we suggest the use of PCR technology to allow early diagnosis and prompt treatment.

Provision of anaesthesia for porcine cardiac transplantation at the veterinary school in Trinidad and Tobago

A successful heterotopic cardiac transplantation was performed between sibling female Yorkshire Juvenile swine. Adequate pre-medication with azaperone and a smooth induction were ensured for both pigs, which were anaesthetized simultaneously with sodium thiopentone followed by endotracheal intubation and intermittent positive pressure ventilation. Inhalation anaesthetic agents were used for maintenance, neuromuscular blockade was achieved with cisatracurium and both fentanyl and tramadol were used to provide analgesia. Invasive monitoring was used in both the donor and recipient. Central venous pressure (CVP) was maintained at > 10 cm H2O and mean arterial pressure (MAP) > 60 mmHg. Heparin was injected during the surgical dissection of the heart in the donor to prevent coronary thrombosis and prior to aortic side clamping for end-to-side anastomosis of the donor heart in the recipient abdomen. After transplantation, the cardiovascular parameters of the recipient showed a MAP of 85-105 mmHg and a CVP of 8-10 cm H2O while echocardiography of the transplanted heart confirmed an ejection fraction (EF) of 80. A functional anaesthetic team was assembled and trained to provide anaesthesia for porcine cardiac transplantation. The transplanted heart suffered pump failure after 69 days and was excised for performance of tissue analysis

Quadruple therapy for initial eradication of Helicobacter pylori in peptic ulcer: comparison with triple therapy.

BACKGROUND: Quadruple therapy appears to be more effective than standard triple therapy in the management of patients with Helicobacter pylori infection who harbor drug-resistant organisms. No data are available on the relative efficacies of triple and quadruple drug regimens from India. METHODS: Consecutive patients with peptic ulcer and H. pylori infection were randomized to receive lansoprazole 30 mg twice daily along with either amoxycillin (500 mg four times daily) and clarithromycin (500 mg twice a day) (Group A), or tri-potassium dicitrato bismuthate (120 mg four times daily), metronidazole (400 mg thrice daily) and tetracycline (500 mg 4 times daily) (Group B) for 10 days. Presence of H. pylori infection was looked for using an in-house urease test and histology before starting treatment, and 30 days after completion of treatment. RESULTS: Twenty-nine of 35 patients in Group A and 24 of 33 in Group B had eradication of infection (82.8% and 72.7% by intention-to-treat analysis, and 87.9% and 85.7% by per protocol analysis, respectively; p = ns). Side-effects occurred in 4 (12%) and 5 (18%) patients in Groups A and B, respectively (p = ns); discontinuation of drugs was required in two patients in group B. CONCLUSIONS: Quadruple therapy for initial treatment of H. pylori infection does not offer any advantage over standard triple therapy in Indian patients.

The spectrum of accidental childhood poisoning in the Caribbean

Objective. To assess accidental poisoning in children in the Caribbean country of Antigua and Barbuda, including the incidence, the types of substances ingested, the age of the children involved, and the clinical outcomes. The results from Antigua and Barbuda were compared with the results of other reports from the English-speaking Caribbean and from the United States of America. Design and Methods. We performed a retrospective review of the charts of all patients less than 13 years old admitted to the Children's Ward at Holberton Hospital in Antigua for accidental poisoning between March 1989 and March 1999. Those data were compared with data from earlier reports from Barbados, Guyana, Jamaica, and the United States of America. Results. In Antigua and Barbuda there were 255 hospital admissions for accidental poisoning among children below 13 years old over that 10-year period. Of the 255 ingestions, 115 of them (45 percent) were in 1-year-old children, 69 (27 percent) were in 2-year-old children, and 26 (10 percent) were in 3-year-old children. These proportions in Antigua and Barbuda are similar to the age patterns seen in the other countries with which we made comparisons. In Antigua and Barbuda there was an annual average of 26 hospital admissions for poisoning for the roughly 20 000 children below 13 years of age, for a rate of 1.3 per 1 000. In comparing the patterns of childhood poisoning in all the countries we studied, we found that, as economic levels rose, there was a shift in the substances ingested, with hydrocarbon and plant ingestions decreasing and chemical and medication ingestions increasing. Conclusions. There is an increasing variety and complexity of poisonous substances ingested as economic conditions improve. This trend would make the establishment of a poison control center for the English-speaking Caribbean a logical step

The initial Trinidad experience with Cine MRI in clinical cardiology

We describe the initial Trinidad experience with Magnetic Resonance Imaging (MRI) and Cine MRI as a diagnostic tool in clinical cardiology. Six patients from the following categories were referred for Cine MRI evaluation: congenital heart disease, valvular heart disease, aortic diseases, cardiomyopathy and intracardiac mass. All patients underwent echocardiography. MRI and Cine MRI were performed on all patients using a Siemens Magnetom 1.0 Tesla MR system at MRI Trinidad and Tobago Ltd. Selected patients underwent Angiography and/or computed tomography (CT) scanning. Clinical data and images of the six patients evaluated are described. MRI and Cine MRI provided excellent anatomical and functional details of the heart and aorta in five patients with dissection of the aorta, aneurysm of the ascending aorta, suspected left ventricular apical thrombus, infiltrative cardiomyopathy and arrhythmogenic right ventricular dysplasia. Technical difficulty was experienced with one patient who had a congenital defect (common atrium). In this study, Cine MRI provided excellent images in all but one patient. This new noninvasive technique enhanced diagnostic capabilities and facilitated management in patients with certain cardiovascular diseases.
