Control ecográfico post inserción de dispositivo intrauterino / Ultrasound control post insertion of intrauterine device

INTRODUCCIÓN: Los dispositivos intrauterinos (DIU) son métodos de anticoncepción reversible, ampliamente usados en el mundo. Se estima que 120 millones de mujeres usan un DIU en el mundo como método anticonceptivo. OBJETIVO: Evaluar los factores de riesgo que puedan relacionarse con una incorrecta inserción del DIU. MÉTODO: 93 pacientes de un Centro de Salud Familiar de la ciudad de Talca, Chile. Utilizando tablas de contingencia se calcularon diferentes medidas de asociación y se compararon los casos de DIU mal posicionado con los casos con uno o más factores de riesgo identificados. RESULTADOS: Se encontró una incidencia de DIU incorrectamente posicionado de un 15,8%, de los cuales hubo un 2,1% de perforación uterina, 2,1% para DIU incrustado y 11,8% para DIU descendido. Se identificaron como factores de riesgo de DIU incorrectamente posicionado la cicatriz de cesárea (RR: 2,31), inserción dificultosa (RR: 3,31) y opinión de un resultado dudoso (RR: 3,64), con una sensibilidad de 73,3%. CONCLUSIONES: La ecotomografía transvaginal es una herramienta crucial para la confirmación de una correcta inserción del DIU y debería ser un examen de rutina ante la presencia de cualquiera de los factores de riesgo identificados.

BACKGROUND: Intrauterine devices (lUDs) are reversible birth control methods that are widely used throug-hout the world. It is estimated that 120 million women use an IUD in the world as a contraceptive. AIM: To assess the risk factors that may relate to incorrect insertion of the IUD. METHODS: The sample included 93 patients of a Family Health Center, Talca, Chile. Using contingency tables, various measures of association were calculated, and the cases of incorrectly positioned IUD were compared with the cases where one or more risk factors were identified. RESULTS: We found an incidence of 15.8% of incorrectly positioned IUD, of which 2.1% presented with uterine perforation, 2.1% with embedment of the IUD and 11.8% with a descended IUD. We identified the following risk factors for incorrectly positioned IUD: cesarean section (RR: 2.31), difficulty on insertion (RR: 3.31) and practitioner's opinión of an uncertain result (RR: 3.64), with a sensitivity of 73.3%. CONCLUSIONS: Transvaginal ultrasound is a crucial tool for confirmation of proper insertion of an IUD and should be considered a routine examination when any of the identified risk factors are present.

Cinta suburetral transobturatriz libre de tensión para el tratamiento de la incontinencia de orina de esfuerzo: 3 años de seguimiento / Tension-free subureteral tape for stress urinary incontinence

Objetivos: Evaluar nuestros resultados en la corrección de la incontinencia de orina de esfuerzo (IOE) con una técnica de cinta suburetral transobturatriz modificada (TOTm) con malla desnuda de polipropileno y anestesia local, midiendo efectividad, calidad de vida y grado de satisfacción por 3 años de seguimiento. Método: Evaluación prospectiva de 56 pacientes operadas entre los años 2003 y 2005, con IOE moderada o severa, según diagnóstico por clínica y cistometría simple. Se logró realizar un seguimiento del 87 por ciento de las pacientes, por 37,9 meses (19-51 meses). Se realizó control con examen físico y se aplicó una encuesta de satisfacción en visita domiciliaria por un grupo independiente de encuestadores. Resultados: Un 88 por ciento de las pacientes se encuentra sin IOE en el examen físico. A la encuesta de satisfacción, las pacientes manifestaron sentirse mejor o mucho mejor en frecuencia miccional diurna (79 por ciento), disfunción del vaciamiento vesical (69 por ciento), dolor pelviano (58 por ciento), urgeincontinencia (84 por ciento) y función sexual (53 por ciento). Un 90 por ciento manifiesta sentirse mejor o mucho mejor de la IOE que antes de la operación. La urgencia o urgeincontinencia de novo apareció en un 6 por ciento. Conclusiones: La técnica TOTm utilizada por nuestro grupo tiene resultados comparables con las técnicas TOT originales, con mejoría significativa en la calidad de vida de las pacientes.

Objective: To review our results in the correction of stress urinary incontinence (SUI) with a modified TOT technique using polypropylene mesh and local anesthesia, measuring effectiveness, quality of life and degree of satisfaction during 3 years of follow-up. Method: Prospective evaluation of 56 patients operated between 2003 and 2005, with modérate or severe SUI, or mixed urinary incontinence with effort predominance, according to clinical diagnosis and simple cystometry. A follow-up of 87 percent of the patients over a period of 37.9 months (19-51 months) was achieved. A physical examination was realized and a survey of satisfaction was applied by a team of independent interviewers on home visits. Results: On physical examination, 88 percent of patients are without SUI. In the survey of satisfaction, the patients manifested feeling better or much better in terms of daytime voiding frequency (79 percent), voiding dysfunction (69 percent), groin pain (58 percent), urge incontinence (84 percent) and sexual function (53 percent); 90 percent manifested feeling better or much better about their SUI than before the operation. De novo urgency or urge incontinence appeared in 6 percent. Conclusions: The modified TOT technique used by our group obtains results that are comparable to those of the original TOT techniques, with a significant improvement in the quality of life of patients.

Influence of pursed-lip breathing on heart rate variability and cardiorespiratory parameters in subjects with chronic obstructive pulmonary disease (COPD) / Influência da respiração freno-labial sobre a variabilidade da frequência cardíaca e parâmetros cardiorrespiratórios em pacientes com doença pulmonar obstrutiva crônica (DPOC)

OBJECTIVES: To assess the effects of pursed-lip breathing (PLB) at rest on the behavior of heart rate (HR) and its variability, and on variations in blood pressure (BP), respiratory rate (RR) and pulse oxygen saturation (SpO2) in subjects with chronic obstructive pulmonary disease (COPD). METHODS: Sixteen subjects with COPD (seven in GOLD stage I, three in GOLD stage II and six in GOLD stage III; mean age 64±11 years; mean FEV1 60±25 percent of predicted value) were assessed at rest, in a seated position, under the following conditions: ten minutes of normal breathing without PLB (R1), eight minutes with PLB (R2) and ten minutes of normal breathing once more (R3). HR was recorded, beat-to-beat, by means of a Polar S810 heart monitor. The RMSSD index (root mean square of the difference between successive R-R intervals) was determined. BP, RR and SpO2 were also assessed during the trials. ANOVA for repeated measures followed by the Tukey test and Kruskal-Wallis test were used for data analysis, with a 5 percent significance level. RESULTS: There was a significant increase in the RMSSD index during R2, in comparison with R1. The HR variation between inspiration and expiration was 8.98 bpm, and the variation between HR at rest and HR with PLB was 8.25 bpm. During R2, RR decreased and SpO2 increased significantly in comparison with R1 and R3. BP values did not show significant changes. CONCLUSIONS: The results showed that PLB produced significant changes in HR, RR and SpO2, and did not alter BP in subjects with COPD. Furthermore, analysis of the RMSSD index showed that PLB promoted increased parasympathetic activity in these subjects, thus indicating that this technique influenced the autonomic cardiac modulation.

OBJETIVOS: Avaliar os efeitos da respiração freno-labial (RFL), em repouso, sobre o comportamento da frequência cardíaca (FC) e sua variabilidade e variações na pressão arterial (PA), frequência respiratória (FR) e saturação parcial de oxigênio (SpO2) em pacientes com doença pulmonar obstrutiva crônica (DPOC). MÉTODOS: Dezesseis pacientes com DPOC (7: estágio GOLD I, 3: estágio GOLD II e 6: estágio GOLD III; média de idade=64±11; média de VEF1=60±25 por cento do predito) foram avaliados em repouso, na posição sentada, nas seguintes condições: 10 minutos respirando normalmente sem RFL (R1), 8 minutos com RFL (R2) e 10 minutos respirando novamente normalmente (R3). A FC foi registrada, batimento a batimento, por meio do frequencímetro Polar S810, e o índice RMSSD (raiz quadrada da média das diferenças entre intervalos RR sucessivos) foi determinado. PA, FR e SpO2 foram também avaliados durante o protocolo. ANOVA para medidas repetidas, seguida pelo teste de Tukey e teste de Kruskal-Wallis foram usados para análise dos dados, com nível de significância de 5 por cento. RESULTADOS: Ocorreu aumento significante no índice RMSSD durante R2 em comparação com R1. A variação na FC inspiração/expiração foi de 8,98 bpm, e a variação na FC em repouso/RFL foi de 8,25 bpm. Durante R2, FR diminuiu e SpO2 aumentou significativamente em comparação a R1 e R3. Os valores de PA não apresentaram modificações significativas. CONCLUSÕES: Os resultados mostraram que a RFL produziu modificações significativas na FC, FR e SpO2 e não alterou a PA em pacientes com DPOC. Além disso, a análise do índice RMSSD mostrou que a RFL promoveu aumento da atividade parassimpática nesses pacientes, indicando que essa técnica influencia a modulação autonômica cardíaca.

There are more asthmatics in homes with high cockroach infestation

Although asthma has been commonly associated with sensitivity to cockroaches, a clear causal relationship between asthma, allergy to cockroaches and exposure levels has not been extensively investigated. The objective of the present study was to determine whether asthma occurs more frequently in children living in homes with high cockroach infestation. The intensity of household infestation was assessed by the number of dead insects after professional pesticide application. Children living in these houses in the metropolitan area of Recife, PE, were diagnosed as having asthma by means of a questionnaire based on the ISAAC study. All children had physician-diagnosed asthma and at least one acute exacerbation in the past year. Children of both sexes aged 4 to 12 years who had been living in the households for more than 2 years participated in this transverse study and had a good socioeconomic status. In the 172 houses studied, 79 children were considered to have been exposed to cockroaches and 93 not to have been exposed. Children living in residences with more than 5 dead cockroaches after pesticide application were considered to be at high infestation exposure. Asthma was diagnosed by the questionnaire in 31.6 percent (25/79) of the exposed group and in 11.8 percent (11/93) of the non-exposed group (P = 0.001), with a prevalence ratio of 3.45 (95 percentCI, 1.48-8.20). The present results indicate that exposure to cockroaches was significantly associated with asthma among the children studied and can be considered a risk factor for the disease. Blattella germanica and Periplaneta americana were the species found in 96 percent of the infested houses.
