Bruschini, Homero;Simonetti, Rogério;Antunes, Alberto A.;Srougi, Miguel;
International braz j urol , 2011, DOI: 10.1590/S1677-55382011000300012
Abstract: purpose: the reported incidence of urinary incontinence (ui) due to bladder dysfunction following surgery of bph is variable. we described the causes of incontinence in a large group of men that developed this unsual complication and analyzed the influence of age on the prevalence of bladder dysfunction. materials and methods: we wvaluated a total of 125 patients with urinary incontinence following surgical treatment for bph : transurethral resection of the prostate (81men) and open prostatectomy (44 men). a third group of 21 patients with incontinence following radical prostatectomy was used for comparison. all patients underwent urodynamic analysis. urethral sphincter insufficiency (usi)was defined as involuntary loss of urine induced by valsalva maneuver in the absence of a detrusor contraction. bladder dysfunction was defined as detrusor overactivity and/or decreased compliance. results: urethral sphincter insufficiency was the most common etiology of urinary incontinence in the three groups of patients. however, bladder dysfunction was observed in 59.3%, 56.8% and 57.1% of patients who underwent transurethral resection, open prostatectomy and radical prostatectomy, respectively. median patient age was 69 and 75 years for patients with and without bladder dysfunction, respectively. a logistic regression model for the presence of bladder dysfunction showed that age was a statistically significant predictor. conclusions: urethral sphincter insufficiency is the main cause of incontinence following surgery for bph. bladder dysfunction may be the isolated cause of incontinence in approximately 25% of patients. the chances of bladder dysfunction rises 5.3% for each year added to patient age. patients older than 70 years have twice the probablility of post procedural incontinence.
Male infertility in spinal cord trauma

Abstract: every year there are 10 thousand new cases of patients victimized by spinal cord trauma (sct) in the united states and it is estimated that there are 7 thousand new cases in brazil. eighty percent of patients are fertile males. infertility in this patient group is due to 3 main factors resulting from spinal cord lesions: erectile dysfunction, ejaculatory disorder and low sperm counts. erectile dysfunction has been successfully treated with oral and injectable medications, use of vacuum devices and penile prosthesis implants. the technological improvement in penile vibratory stimulation devices (pvs) and rectal probe electro-ejaculation (rpe) has made such procedures safer and accessible to patients with ejaculatory dysfunction. despite the normal number of spermatozoa found in semen of spinal cord-injured patients, their motility is abnormal. this change does not seem to be related to changes in scrotal thermal regulation, frequency of ejaculation or duration of spinal cord damage but to factors related to the seminal plasma. despite the poor seminal quality, increasingly more men with sct have become fathers through techniques ranging from simple homologous insemination to sophisticated assisted reproduction techniques such as intracytoplasmic sperm injection (icsi).

Borghesi, Gustavo;Simonetti, Rogerio;Goldman, Suzan M.;Szejnfeld, Jacob;Srougi, Miguel;Ortiz, Valdemar;Bruschini, Homero;
International braz j urol , 2006, DOI: 10.1590/S1677-55382006000300015
Abstract: objectives: in this preliminary study we report the development of the video urodynamic technique using magnetic resonance imaging (mri). materials and methods: we studied 6 women with genuine stress urinary incontinence, diagnosed by history and physical examination. urodynamic examination was performed on multichannel equipment with the patient in the supine position. coughing and valsalva maneuvers were performed at volumes of 150, 250 and 350 ml. simultaneously, mri was carried out by using 1.5 t ge signa cv/i high-speed scanner with real time fluoroscopic imaging possibilities. fluoroscopic imaging was accomplished in the corresponding planes with t2-weighted single shot fast spin echo sequences at a speed of about 1 frame per second. both studies were recorded and synchronized, resulting in a single video urodynamic examination. results: dynamic mri with cine-loop reconstruction of 1 image per second demonstrated the movement of all compartment of the relaxed pelvis during straining with the concomitant registration of abdominal and intravesical pressures. in 5 patients, urinary leakage was demonstrated during straining and the valsalva leak point pressure (vlpp) was determined as the vesical pressure at leak subtracted from baseline bladder pressure. mean vlpp was 72.6 cm h2o (ranging from 43 to 122 cm h2o). conclusions: the concept of mri video urodynamics is feasible. in a clinical perspective, practical aspects represent a barrier to daily use and it should be recommended for research purposes.
Conscious Use of the Virtual Sphere Modeling in the Simulation of Passive Night Cooling of Buildings  [PDF]
Marco Simonetti
Open Journal of Energy Efficiency (OJEE) , 2016, DOI: 10.4236/ojee.2016.52006
Abstract: Night cooling of building is considered as a technology with a high potential of impact on air conditioning energy needs. Natural ventilation should be the first option for night cooling, for obvious reasons of energy savings. The evaluation of the capacity of the building to cool down its structures during night ventilation is of primary concern during preliminary design stage, even though night cooling with natural ventilation is among the most complex problem to be modelled in details. Some modelling options are available, assuming different simplifications in space and time. Among them, virtual sphere modelling has been proposed in the past as a quick way to perform dynamic simulation of the night cooling of buildings. In this paper, the theoretical origin of the virtual sphere model is recalled, underlining its limits in case of application to buoyancy driven night cooling of buildings. The limits can explain the disagreements of virtual sphere prediction with other methods reported in literature and may stimulate a more conscious application of the model and further improvements of the method.
Le service militaire et la condition des femmes en Isra l

Abstract: Military Service and Women’s Conditions in Israel: Some Elements of ReflectionWomen’s condition in Israel finds his roots in several factors: cultural, socio-economical, religious as a reflection of the complexity of people in this country. The geopolitical situation, linked to the state of war of Israel, also affect women’s life in Israel. Israel is one of the few countries, and the only western country in the world, that drafts women in the army compulsory service. In particular this element creates interesting paradoxes between women’s contribution to the defence of the country, the status traditionally attributed to them and their own path to emancipation in the Israeli society.The Israeli Defence Force (IDF) is a central institution for the Israeli society. IDF draws the societal hierarchy in the State, determines the attribution of resources and it represents a way of access to the political arena in Israel. Responding to the national duties, among which the compulsory service is the highest expression, is what makes one a good citizen. But in Israel a wide cleavage between women and men is perpetrated in the army and into the military organisation itself. By consequence the gender division in the army is reproduced in civil life as well. Women serve in the army for a shorter period of time, their contribution, for most of them, is reduced to female work and, once freed by the army duty, they do not enjoy socio-economical opportunities as men do. Many feminists and that part of the women movements which had more influence in the Parliament, started to focus their attention on the achievement of a wider range of jobs and positions for women in the army. These last decades have seen important changes in the Israeli army that have modified its structure in particular concerning the gender relations and the women’s role in the military. The opening of flight courses for officers to women was an important starting point as well as the opening of combat units. The second Lebanon war has seen for the first time, since the birth of the Israeli Nation, women’s operational participation during a conflict. This marks a big change for the Israeli army, which may lead to a new balance of opportunities between women and men and a transformation of the classical roles attributed to women and their public participation in social and political life in Israel. In order to understand the social and gender implications of the presence of women in the army, the article will start considering the meaning of the compulsory service in Israel at the light of the centrality

Fonseca, Homero;
Anais da Escola Superior de Agricultura Luiz de Queiroz , 1976, DOI: 10.1590/S0071-12761976000100036
Abstract: in the present work the occurrence of aflatoxin in peanut (arachis hypogaea l.) in the region of fernandópolis, s.p., was investigated in three stages, from harvest to industrialization: a) by the time the grower sells it to the oil mill: epochs i and ii; b) during its storage prior to milling: epochs iii and iv, and c) after oil extraction (peanut flour) : epochs v and vi. in each stage two collections, of 10 samples each, were made in a total of 40 samples of peanuts and 20 samples of peanut flour. from the results the following conclusions could be drawn: 1) all samples were toxic, except one; 2) the toxicity level in terms aflatoxin b1 was high, for 51.7% of the samples were in the category "high" and 38.3% in the category "very high"; 3) the levels of aflatoxin in the samples grew from epoch i to epoch iv: mean values of 0.54 to 2.14 ppm, decreasing in epoch v and vi: 1.04 ppm; 4) five samples were excessively toxic with more than 10.00 ppm; 5) aflatoxin and high moisture content are present in most raw material when the grower takes it to the oil mill; 6) the miller does not take action to dry the moist material, contributing, this way, to permit an increase in the aflatoxin levels, during storage.
