[A Spanish multicenter trial of TVT for female urinary incontinence].

OBJECTIVE: The purpose of this study was to evaluate results and complications of TVT in a large series from different hospital centers in Spain. METHOD: We retrospectively studied the results of TVT placement from 6 centers with 272 consecutive patients (median follow-up was 636 days). All types of stress urinary incontinence with a surgical indication were included and no previous conditions were established regarding the indication. No protocol was used for either the intervention or postoperative support measures. Data collection was protocolized and carried out using a common questionnaire that was completed by an urologist at each center from 3 to 6 months after the intervention and then annually. All patients who underwent intervention were asked about their satisfaction with the outcome. Multivariate studies were made to identify the factors that influenced the recovery of continence and the occurrence of complications. RESULTS: 92.1% of patients were continent and 2.4% have not shown any improvement. 91.6% of the patients claimed to be satisfied whereas only 2.7% were dissatisfied. After four years only 2.8% of patients showed mild incontinence with time and 0.4% had moderate incontinence. Only previous surgery for incontinence was found to be significantly unfavorable factor for achieving postoperative continence. CONCLUSION: We have reproduced a scenario closer to daily clinical reality than the results of series from a single institution or analyses using stricter selection criteria. This multicenter study verifies the viability and reproducibility of TVT with minimal complications in centers where patients are not selected and where not all urologists are specialized in urinary incontinence.

Torpor characteristics and energy requirements of furless Siberian hamsters.

After approximately 10 wk of exposure to decreasing day lengths, Siberian hamsters (Phodopus sungorus) begin to display spontaneous torpor bouts several times each week. Torpor is associated with reduced daily energy expenditure and lower food consumption and ameliorates the thermoregulatory challenges of winter. We tested the extent to which the energy savings conferred by daily torpor depend on the presence of an insulative pelage. Female hamsters were housed in a winter day length (8L:16D) at 5 degrees C; daily food intake and torpor characteristics were recorded for 5 wk in shaved (furless) or normal hamsters. Torpor-bout incidence decreased by 62% in furless hamsters, but the duration of individual bouts and the minimum body temperature attained during torpor were unaffected by loss of pelage. Body temperature declined more rapidly during entry into torpor and increased more slowly during arousal from torpor in furless than in control hamsters. Energy savings per torpor bout, assessed by the amount of food consumed on days that included a torpor bout, was substantially greater in normal than in furless hamsters (16.0% vs. 3.3%); this difference likely reflects the increased cost of thermoregulation during torpor, as well as the increased caloric expenditure incurred by furless hamsters during arousal from torpor. An insulative pelage may be a prerequisite for the energetic benefits derived from heterothermy in this species.

[Paracoccidiodomycosis (South American blastomycosis): general review and report of cases].

The author presents and comments upon 19 cases of paracoccidiodomycosis (South American Blastomycosis). He sums up the fundamental epidemiologic and parasitologic aspects of the disease. He points out the diversity of its anatomoclinical features, and underlines the role of the pathologic anatomy in the diagnosis of the disease which necessitates of course an immunologic study. Histology also allows the appreciate the effect of specific treatments and to emphasize the formidable sclerogenic tendency of the disease when the patient has not been long enough under treatment.

[Diverticulum of the right ventricle with dilated myocardiopathy].

We report on a newborn infant with right ventricular diverticulum associated to dilated myocardiopathy, who was diagnosed by two-dimensional echocardiography within 24 hours after vaginal delivery. We believe this case represents the youngest one ever diagnosed with this disease.

[Persistent truncus arteriosus. Echocardiographic study of 8 cases].

Eight patients (4 male, 4 female) with persistent truncs arteriosus diagnosed by two-dimensional echocardiography are presented. Age ranged from 1 to 19 days. Diagnosis was based on the demonstration of a single vessel giving rise to the aorta, pulmonary arteries and coronary circulation. In 6 patients we were able to define the types of the truncus: in 4 patients corresponded to type I (with partial presence of aorto-pulmonary septum) and in 2 cases corresponded to type II (without existence of septum). All cases had a dilated truncus (1.13 +/- 0.06 cm, range 1.05-1.3 cm), with moderate overriding (52% range 30%-65%) and an infundibular ventricular septal defect (0.6 +/- 0.08 cm, range 0.45-0.85 cm). In 2 cases we could also demonstrate the presence of an interruption of the aortic aorta. We conclude that two-dimensional echocardiography (specially parasternal long-short axis views and subcostal for right or leftout flow tracts axis views) gives sufficient information about this cardiac malformation, which can be completed by the use of pulsed Doppler ultrasound.

Anomalous origin of the left coronary artery from the pulmonary artery. Surgical alternatives depending of the age of the patient.

Four cases of anomalous origin of the left coronary artery from the pulmonary artery, three of which were operated upon in our Centre, are presented. An aortocoronary bypass with reversed autologous saphenous vein was carried out in both of the children; and in the adult, the anomalous ostium was closed from the interior of the pulmonary artery. After 84, 72, and 4 months of evolution, respectively, they were found to be asymptomatic, the mitral insufficiency had disappeared and the venous graft remained patent. In this paper, the clinical form of presentation, diagnostic possibilities and surgical treatment are analysed.

[Prolapse of the mitral valve. Study using bidimensional echocardiography].

Mitral valve prolapse is frequent in childhood. The use of two-dimensional echocardiography may enable more accurate diagnosis and assessment of the degree of valve involvement. Twenty five (1.9%) of all children studied by two-dimensional echocardiography fulfilled the diagnostic criteria for mitral valve prolapse. In 48% it was associated to a different congenital heart as normality. The apical four chamber and parasternal long and short axis views were used, and cases were graded according to the severity of the prolapse. Diagnosis was made in 44% of cases by the apical four chamber view, which was the best projection to detect the abnormality. Cases of moderate and severe prolapse were also detected in the parasternal long axis view. All patients were asymptomatic but they were all controlled detect progression to mitral insufficiency of the appearance of other complications.
