Factores asociados al dolor crónico posoperatorio en pacientes llevados a herniorrafia inguinal

Introducción: La herniorrafia inguinal se asocia hasta en un 50% de los casos con dolor crónico posoperatorio (DCP), y en algunos puede ser incapacitante. En este estudio se evaluaron los factores asociados al DCP en pacientes llevados a herniorrafia inguinal. Métodología: Se realizó un estudio de cohorte multicéntrico. Se obtuvo información sociodemográfica y de antecedentes personales. Se determinó la presencia e intensidad de dolor agudo posoperatorio (DAP) y se evaluaron los factores asociados al DCP con seguimiento a los dos meses del posoperatorio. Se establecieron asociaciones con la prueba chi cuadrado. Mediante una regresión lineal se evaluó el papel de los factores de confusión. Resultados: Se analizaron 108 pacientes. 54.7% presentaron DCP. La edad menor de 40 años, el DAP no controlado, el DAP severo, y el dolor no controlado entre la primera y tercera semanas del POP se relacionaron con mayor riesgo de DCP. La edad mayor a 65, el uso de opioides intratecales, la visualización y preservación de los nervios durante la cirugía, y el uso de tres o más analgésicos intravenosos con bloqueo ilioinguinal/iliohipogástrico fueron factores protectores. Discusión: El DCP es frecuente en nuestro medio. La prevención y manejo eficientes del DAP utilizando analgesia multimodal, el uso de opioide intratecal, y la identificación y preservación de los nervios en el área quirúrgica ayudan a prevenir el desarrollo de DCP. Estudios de este tipo realizados a una escala más grande, permitirán identificar otros factores relacionados con esta patología. Palabras clave: Dolor crónico postoperatorio, herniorrafia inguinal, inguinodina, factores asociados.

Aseguramiento para la población pobre: una herramienta de protección financiera

La financiación de los sistemas de salud en los países en desarrollo mediante esquemas de aseguramiento, presenta el desafío estructural de la informalidad de los mercados laborales. Ni el esquema de financiamiento comunitario ni el del subsidio a la oferta, parecen ofrecer una garantía de acceso a los grupos más vulnerables. Pero la extensión de esquemas de seguro subsidiado también implica mayores presiones sobre el gasto social. Este artículo es una revisión de la literatura sobre el tema, en el cual se revisan experiencias internacionales de los tipos mencionados, y se analiza su relevancia para Colombia.

Representaciones sociales de la medicina complementaria y alternativa (MCA) para el cáncer en estudiantes universitarios de carreras de ciencias de la salud

Se realizó un estudio cualitativo exploratorio con estudiantes de carreras de Ciencias de la Salud con el objetivo de comprender las representaciones sociales que tienen acerca de la Medicina Complementaria y Alternativa (MCA) para el cáncer. Se desarrollaron grupos focales y la información obtenida fue analizada a través del Análisis Temático e interpretada con base en la Teoría de las Representaciones Sociales. Se encontraron diversas representaciones sociales asociadas con la definición, los objetivos, los tratamientos, la eficacia, las fuentes de información y el origen de la MCA. En conclusión se evidenció una alta tendencia a la aceptación y a la manifestación de una actitud positiva, aunque ambivalente frente a la MCA, además de un desconocimiento por la diferenciación conceptual entre este tipo de Medicina y la Medicina Popular. La cultura y las creencias sociales predominan en las representaciones sociales que tienen los estudiantes de la MCA para el cáncer, pese a su formación académica.

Perfil epidemiológico de la prevalencia de hipoacusia en un grupo de empleados que trabaja en el ambiente urbano, 2015

El propósito de este estudio es determinar la relación entre la exposición ocupacional y los niveles de audición en trabajadores urbanos en espacio abierto (aseo urbano en general). Se realizó un estudio de corte transversal con 491 personas que incluyen hombres y mujeres, cuyo ambiente laboral es el espacio abierto de la ciudad. Los datos se obtuvieron durante los exámenes médicos periódicos realizados en el año 2014 a los empleados de una empresa cuya actividad económica es el aseo urbano, que incluye recolección de basuras, cuidado forestal y de prados de uso común, y limpieza del borde de los andenes. Se realizó estadística descriptiva para las características demográficas y razón de disparidad u Odds Ratio (OR) para buscar la relación de antecedentes y hábitos personales con el riesgo de desarrollar pérdida auditiva. De las 491 personas expuestas a niveles altos de ruido ocupacional, 62% presentó pérdida auditiva, de los cuales la mayoría se desempeña como guadañadores y cortadores de césped, y son personas que llevan trabajando entre 1-5 años en la empresa. Se encontró un aumento estadísticamente significativo entre la baja escolaridad y el riesgo de sufrir hipoacusia (p=0.0001) y un efecto protector del uso de motocicleta y audífonos. La enfermedad vascular periférica, la práctica de tejo y la diabetes mostraron una fuerte tendencia a aumentar el riesgo. La pérdida auditiva encontrada en este grupo no se puede relacionar directamente con la exposición ocupacional a ruido, a pesar de ser trabajos que se llevan a cabo en el espacio urbano. Sin embargo, la baja escolaridad favorece la lesión auditiva y puede verse acelerada por enfermedades de alta prevalencia como diabetes y practicas recreacionales locales.

Evaluation of Mid-upper Arm Circumference in Pre-school Children: Comparison Between NCHS/CDC-2000 and WHO-2006 References

We aimed to evaluate the classification of arm circumference (AC) in pre-school children by using National Center for Health Statistics (NCHS/CDC-2000) and World Health Organization (WHO-2006) references. We evaluated 205 children: weight, height and AC were assessed and the body mass index (BMI) was calculated. The BMI values were classified into Z-scores by the WHO referential. The AC was classified into Z-cores by two references, comparing the whole-sample value and among groups (tercis) of BMI Z-score. The correlation was also evaluated between differences of AC with BMI Z-score. The WHO referential classified the AC in Z-scores greater than the NCHS/CDC, which is more specific and less sensitive than the NCHS/CDC for lean children and at the same time more sensitive and less specific for children with overweight. In conclusion, a significant difference in the AC classification occurs according to the referential used.

Longitudinal Study of Growth of Children With Unilateral Cleft-Lip Palate From Birth to Two Years of Age

Objective: To study the growth of children with complete unilateral cleft lip and palate (UCLP) from birth to 2 years of age and to construct specific UCLP growth curves. Design: Physical growth was a secondary outcome measure of a National Institutes of Health-sponsored longitudinal, prospective clinical trial involving the University of Florida (United States) and the University of Sao Paulo (Brazil). Patients: Six hundred twenty-seven children with UCLP, nonsyndromic, both genders. Methods: Length, weight, and head circumference were prospectively measured for a group of children enrolled in a clinical trial. Median growth curves for the three parameters (length, weight, head circumference) were performed and compared with the median for the National Center for Health Statistics (NCHS) curves. The median values for length, weight, and head circumference at birth and 6, 12, 18, and 24 months of age were plotted against NCHS median values and statistically compared at birth and 24 months. Setting: Hospital de Reabilitacao de Anomalias Craniofaciais, Universidade de Sao Paulo, Bauru, Brazil (HRAC-USP). Results: At birth, children of both genders with UCLP presented with smaller body dimensions in relation to NCHS median values, but the results suggest a catch-up growth for length, weight, and head circumference for girls and for weight (to some degree) and head circumference for boys. Conclusions: Weight was the most compromised parameter for both genders, followed by length and then head circumference. There was no evidence of short stature. This study established growth curves for children with UCLP.

Avaliação da qualidade de vida relacionada à saúde de cortadores de cana-de-açúcar nos períodos de entressafra e safra

OBJETIVO: Avaliar a qualidade de vida relacionada à saúde de cortadores de cana-de-açúcar. MÉTODOS: Estudo longitudinal em uma usina sucroalcooleira no Oeste do estado de São Paulo de abril (final da entressafra) a outubro (final da safra) de 2010. Foram avaliados 44 cortadores de cana-de-açúcar tabagistas e não tabagistas em três períodos: ao final da entressafra, no fim do terceiro mês de safra e no final da safra. A qualidade de vida relacionada à saúde foi avaliada pelo questionário Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). Foram realizados análise de variância para medidas repetidas e teste de Friedman para comparar a qualidade de vida entre os períodos. Utilizou-se o teste de Goodman para identificar a frequência dos trabalhadores cujo escore aumentou nos períodos de safra em comparação com a entressafra (respondedores positivos), considerando-se as variáveis qualitativas dos domínios do SF-36. RESULTADOS: Ao final da entressafra, 23% dos trabalhadores desistiram do trabalho; 27% eram tabagistas. Houve decréscimo significativo no domínio vitalidade no final da safra em comparação com a entressafra. Os desistentes apresentaram maior escore no domínio aspecto social em relação ao grupo que permaneceu no trabalho. Não houve diferença na qualidade de vida relacionada à saúde entre tabagistas e não tabagistas. No entanto, observou-se maior percentual de respondedores positivos entre não tabagistas nos domínios aspecto físico, social e emocional nos três meses de safra e nos domínios estado geral de saúde e aspecto social nos seis meses de safra, quando comparados aos tabagistas. CONCLUSÕES: A qualidade de vida relacionada à saúde em cortadores de cana-de-açúcar mostrou-se diminuída após o período de safra no domínio vitalidade. Os trabalhadores que permaneceram na safra são os que apresentaram piores aspectos sociais, o que mostra a necessidade de promoção de políticas assistencialistas de saúde a essa população específica, principalmente durante a safra canavieira.

Social support and infant malnutrition: a case-control study in an urban area of Southeastern Brazil

The relationship between malnutrition and social support was first suggested in the mid-1990s. Despite its plausibility, no empirical studies aimed at obtaining evidence of this association could be located. The goal of the present study was to investigate such evidence. A case-control study was carried out including 101 malnourished children (weight-for-age National Center for Health Statistics/WHO 5th percentile) aged 12-23 months, who were compared with 200 well-nourished children with regard to exposure to a series of factors related to their social support system. Univariate and multiple logistic regressions were carried out, odds ratios being adjusted for per capita family income, mother's schooling, and number of children. The presence of an interaction between income and social support variables was also tested. Absence of a partner living with the mother increased risk of malnutrition (odds ratio 2.4 (95 % CI 1.19, 4.89)), even after adjustment for per capita family income, mother's schooling, and number of children. The lack of economic support during adverse situations accounted for a very high risk of malnutrition (odds ratio 10.1 (95 % CI 3.48, 29.13)) among low-income children, but had no effect on children of higher-income families. Results indicate that receiving economic support is an efficient risk modulator for malnutrition among low-income children. In addition, it was shown that the absence of a partner living with the mother is an important risk factor for malnutrition, with an effect independent from per capita family income, mother's schooling, and number of children.

Agrupamento de países segundo indicadores de padrão de vida

Foram estudados 125 países avaliados por um conjunto de 26 indicadores básicos, de saúde, econômicos e educacionais, usando-se três métodos estatísticos multivariados: Análise de Agrupamento, Análise de Componentes Principais e Análise de Variância Multivariada. As variáveis mais discriminatórias foram a expectativa de vida, as taxas de mortalidade infantil e de menores de cinco anos, as taxas de natalidade e de fertilidade e a taxa de matrícula no segundo grau para o sexo feminino. Os países foram ordenados de acordo com um índice de padrão de vida e separados em cinco grupos.

Response to Treatment in a Prospective Cohort of Patients with Large Ulcerated Lesions Suspected to Be Buruli Ulcer (Mycobacterium ulcerans Disease)

Background: The World Health Organization (WHO) advises treatment of Mycobacterium ulcerans disease, also called Buruli ulcer'' (BU), with a combination of the antibiotics rifampicin and streptomycin (R+S), whether followed by surgery or not. In endemic areas, a clinical case definition is recommended. We evaluated the effectiveness of this strategy in a series of patients with large ulcers of >= 10 cm in longest diameter in a rural health zone of the Democratic Republic of Congo (DRC).Methods: A cohort of 92 patients with large ulcerated lesions suspected to be BU was enrolled between October 2006 and September 2007 and treated according to WHO recommendations. The following microbiologic data were obtained: Ziehl-Neelsen (ZN) stained smear, culture and PCR. Histopathology was performed on a sub-sample. Directly observed treatment with R+S was administered daily for 12 weeks and surgery was performed after 4 weeks. Patients were followed up for two years after treatment.Findings: Out of 92 treated patients, 61 tested positive for M. ulcerans by PCR. PCR negative patients had better clinical improvement than PCR positive patients after 4 weeks of antibiotics (54.8% versus 14.8%). For PCR positive patients, the outcome after 4 weeks of antibiotic treatment was related to the ZN positivity at the start. Deterioration of the ulcers was observed in 87.8% (36/41) of the ZN positive and in 12.2% (5/41) of the ZN negative patients. Deterioration due to paradoxical reaction seemed unlikely. After surgery and an additional 8 weeks of antibiotics, 98.4% of PCR positive patients and 83.3% of PCR negative patients were considered cured. The overall recurrence rate was very low (1.1%).Interpretation: Positive predictive value of the WHO clinical case definition was low. Low relapse rate confirms the efficacy of antibiotics. However, the need for and the best time for surgery for large Buruli ulcers requires clarification. We recommend confirmation by ZN stain at the rural health centers, since surgical intervention without delay may be necessary on the ZN positive cases to avoid progression of the disease. PCR negative patients were most likely not BU cases. Correct diagnosis and specific management of these non-BU ulcers cases are urgently needed.

Salmonelas e coliformes fecais em águas de bebida para animais

Sixty small farms of Botucatu County, S. Paulo, Brazil, given over to cattle breeding were studied. These farms account for 15% of the total of 402 farms that exist in the county. The sample was drawn by simple probabilistic technique. There were found to be one hundred and thirteen drinking places located on the farms. Samples of water were taken from these drinking places and examined for bacteria of the genus Salmonella, for the determination of Most Probable Number (MNP) of fecal coliform bacteria as well as determination of the water's pH. Water temperature was measured before collection. Samples from 15 drinking places (13.3%) were positive for Salmonella. The drinking places belonged to 12 of the sixty farms studied (20%). The following serotypes were identified: S. dublin, S. newport, S. madelia, S. IV 43:g,z57:-, S. saphra, S. glostrup, S. IV ochsenzool; S. I9,12:i:- and two new serotypes S. IV 41:z52:- and S. IV 50:d:-. Of the 113 samples studied 14 (12.4%) presented MPN/100ml of fecal coliforms above 4,000. There was no relationship between MPN/100ml of fecal coliforms above 4,000 and positivity for Salmonella. Highest positivity both for Salmonella and MPN/100mL of fecal coliforms over 4,000 occurred at temperatures above 18 degrees C. As regards pH, in both situations the highest positivity occurred between 6.0 and 7.0.
