Revista chilena de obstetricia y ginecología , 2011, DOI: 10.4067/S0717-75262011000300002
Abstract: background: bilateral oophorectomy, practiced at the time of hysterectomy, is understood as a prophylactic measurement for ovarian cancer, becoming the most frequently extracted healthy organ. prophylactic oophorectomy has been reported at a frequency of 40-55% cases of hysterectomy. it has been demonstrated that women show a decrease of the sexual function after hysterectomy with bilateral oophorectomy more frequently than the women with hysterectomy only. aim: to compare the characteristics of the sexuality in a group of women with and without oophorectomy, at the time of surgery and at 6 months postoperative. method: analytical, longitudinal and prospective study of 67 women, 35 with hysterectomy (gh) and 32 hysterectomized and oophorectomized (gh-o). two surveys, at the time of surgery and six months later were carried out to determine the sexual function. results: a significant difference was found between the gh-o group and the gh group in prevalence and frequency of dispareunia, frequency of orgasm, frequency of intercourse, and sexual excitation. conclusions: the decision for oophorectomy must be made with caution in the case of the women with low risk of ovarian cancer, considering the individual risk of sexual dysfunction as well as the risks inherent in the surgery.

Abstract: Antecedentes: La ooforectomía bilateral, al momento de la histerectomía, es comprendida como una medida profiláctica para cáncer de ovario convirtiéndose en el órgano sano más frecuentemente extraído. La extracción profiláctica de ovarios alcanza una frecuencia del 40-55% de los casos de histerectomía. Se ha demostrado que las mujeres con histerectomía y ooforectomía muestran con mayor frecuencia deterioro de la función sexual que aquellas con sólo histerectomía. Objetivo: Comparar las características de la función sexual de un grupo de mujeres histerectomizadas, con y sin extracción de ovarios, a los 6 meses posteriores a la cirugía. Método: Estudio analítico, longitudinal, prospectivo en 67 mujeres: 35 histerectomizadas (GH) y 32 histerectomizadas con ooforectomía (GH-O). Para la recolección de los datos se aplicó un cuestionario al tercer día posterior a la cirugía, y repetido a los 6 meses para determinar las características de la función sexual. Resultados: Después del control de variables basales, se produce una diferencia significativa entre el GH-O y el GH en cuanto a prevalencia y frecuencia de dispareunia al sexto mes, frecuencia de orgasmo, frecuencia de relaciones sexuales y grado de excitación sexual. Conclusiones: La decisión de realizar una ooforectomía debe ser enfrentada con precaución en el caso de las mujeres con bajo riesgo de cáncer de ovario, considerando el riesgo individual de alteraciones sexuales, así como también, el riego inherente a la cirugía.

Abstract: objective: to investigate the association between the urban area of origin of patients and the prevalence of hypersensitivity pneumonitis (hp), induced by avian antigens. material and methods: a case-control study was conducted in 1999 at the national institute of respiratory diseases (nird). cases were 109 consecutive hp patients and controls were 184 patients: 39 with idiopathic pulmonary fibrosis (ipf), 63 with pulmonary tuberculosis (ptb), and 82 with asthma. mexico city and surrounding counties (sc) were divided into 5 geographical areas: 1) downtown; 2) north-east (ne); 3) south-east (se); 4) north-west (nw) and 5) south-west (sw). statistical analysis consisted of calculation of disease prevalence by urban area; associations were assessed with odds ratios and 95% confidence intervals. multivariate analysis with multiple logistic regression was performed to adjust for age, gender and socioeconomic level. results: eighty hp cases were located in the ne southernmost and se northernmost areas of mexico city (48 and 32, respectively) (or= 3.86; 95% ci 2.17-6.96). thirty-six controls with asthma came from the sw area, (where nird is located) (p<0.05), and four from sc. controls with ptb and ipf were scattered throughout the study area. conclusions: the ne southernmost and se northernmost areas were associated with hp. the cause of hp may not be geographical; a garbage dump used to be located in this area, suggesting that exposure to organic particles might contribute to the development of hp in susceptible individuals.
Properties of Submillimeter Galaxies in a Semi-analytic Model using the "Count Matching" Approach: Application to the ECDF-S

Abstract: We present a new technique for modeling submillimeter galaxies (SMGs): the "Count Matching" approach. Using lightcones drawn from a semi-analytic model of galaxy formation, we choose physical galaxy properties given by the model as proxies for their submillimeter luminosities, assuming a monotonic relationship. As recent interferometric observations of the Extended Chandra Deep Field South show that the brightest sources detected by single-dish telescopes are comprised by emission from multiple fainter sources, we assign the submillimeter fluxes so that the combined LABOCA plus bright-end ALMA observed number counts for this field are reproduced. After turning the model catalogs given by the proxies into submillimeter maps, we perform a source extraction to include the effects of the observational process on the recovered counts and galaxy properties. We find that for all proxies, there are lines of sight giving counts consistent with those derived from LABOCA observations, even for input sources with randomized positions in the simulated map. Comparing the recovered redshift, stellar mass and host halo mass distributions for model SMGs with observational data, we find that the best among the proposed proxies is that in which the submillimeter luminosity increases monotonically with the product between dust mass and SFR. This proxy naturally reproduces a positive trend between SFR and bolometric IR luminosity. The majority of components of blended sources are spatially unassociated.

Abstract: objective: to characterize the situation of pulmonology journals published in latin america. methods: a survey was conducted in a meeting sponsored by the latin american thoracic society. each journal editor presented a report and answered a questionnaire. results: improving information acquisition is the main motivation for pulmonology societies to edit their own journals, whereas disseminating medical knowledge and reporting experiences are the main motivations for authors to submit papers. the most common failing in the manuscripts submitted is poor compliance with the journal guidelines. improving author-editor-reviewer relationships would be the best strategy for improving the quality of manuscripts. suggestions for improving latin american journals included the following: promoting professionalism in editorial tasks; encouraging manuscript reviewers to be more meticulous; and embracing international norms for editing medical journals. the following major problems were reported: a lack of regular, appropriate periodicity of issues; a shortage of original papers that are considered 'milestones' in the specialty; a low rejection rate for submitted papers; a high turnover of editors. conclusion: based on our findings, we can make the following recommendations: although many journals are available in electronic form, they should also be maintained in print form; each journal should divulge its subscription fee, even if it is included in the annual society membership dues; although each latin american country might decide to publish its own pulmonology journal, the feasibility of publishing a multinational latin american pulmonology journal should be explored.

Abstract: a survey was conducted in a meeting sponsored by alat (latin american association of thoracic diseases). each of the seven editors reported about their journal and answered a questionnaire. the improvement in knowledge divulgation is the main motivation of respiratory societies to edit their own journals. to disseminate medical knowledge and report experiences, are the main motivations of authors to submit papers. the most common deficiency of submitted manuscripts is a bad compliance with journal requirements. an improvement in the relationship between author-editor-reviewer should be the best strategy to enhance the quality of the manuscripts. suggestions to improve the latin american journals included to professionalize editorial work, to increase the meticulousness of manuscripts reviewers and to reinforce international norms for editing medical journals. some major problems reported were a lack of a regular and adequate periodicity in publishing the issues, lack of original papers submitted that mean a "milestone" for the specialty a low percentage of submitted papers rejection and a high and frequent turnover of editors. although several journals are available in electronic indices, they should be maintained in their printed form. each journal should have printed its subscription fee, even considering that its subscription is included in the annual society membership fee. the feasibility to generate a multinational latin american journal on respiratory diseases should be explored (rev méd chile 2007; 135:1072-5)
