ABSTRACT Introduction: When the vasectomy reversal (VR) fails, and the patient desires natural conception with his sperm, vasectomy re-reversal (VRR) is the only alternative. Purpose: To determine the VRR effectiveness and whether specific parameters can be associated with its success. Materials and Methods: We retrospectively evaluated 18 consecutive vasectomized patients, who had failed their VR through bilateral vasovasostomy, and posteriorly were submitted to VRR. The parameters of the study were: age of the patients, elapsed time between vasectomy and VRR (V-VRRt), elapsed time between VR and VRR (VR-VRRt), presence of spermatozoa in the proximal vas deferens fluid (SptzVDF) in the VRR and results of semen analysis after VRR (SA-VRR). Results: The mean of the age of the patients was 44.11±6.55 years (32.0-57.0), the mean of V-VRRt was 11.76±6.46 years (1.5-25.0) and the mean of VR-VRRt was 2.13±2.27 years (0.5-10.0). SptzVDF in the VRR were found bilaterally in 8 patients, unilaterally in 4 and absent in 6. SA-VRR demonstrated normozoospermia in 9 patients, oligozoospermia in 3 and azoospermia in 6, with patency rate of 66.67%. SA-VRR showed statistically significant dependence only with SptzVDF in the VRR (p <0.01). Conclusions: VRR was effective in restoring the obstruction in more than half of the patients. Furthermore, the presence of spermatozoa in the vas deferens fluid was the parameter associated with the VRR success.

Abstract 29. The objective of this investigation was to understand the attention of the patient in urgent situation of the mobile pre-hospital service to the Emergency Hospital service. It is a qualitative research, with the methodological reference of the theory based on the data. Data collection occurred through semi-structured interviews between April and September 2016, with a theoretical sampling of 24 participants, among professionals from a Trauma Reference Hospital, Fire Brigade Battalion Military and advanced operational Base of the emergency Mobile service . Data analysis was done by initial and focused coding. Three categories were obtained: (1) attending to the so-called, (2) Delivery of patient care at the place of occurrence and (3) taking care of the patient in the hospital service, which support the phenomenon: "Performing the Attention of the patient in urgent situation of the mobile APH for the Emergency Hospital Service ". It is concluded that reception of the patient in an emergency situation is initiated with the activation of the mobile pre-hospital care service. The continuity of this attention occurs in the hospital environment by the team who performs the necessary care, according to the severity of the patient's clinical situation.

Objective to identify burnout syndrome levels among nurses at a university hospital. Method a cross-sectional study conducted in a university hospital in southern Brazil, with 106 nurses. Data was collected through a questionnaire composed of two self-answered instruments: personal and professional characterization form and the Maslach Burnout Inventory. Results the nurses participating in the study presented moderate burnout levels for the three subscales: emotional exhaustion (21.9±5.0), depersonalization (8.1±2.6) and personal fulfillment (30.4±3.2). The nurses working in the surgical center had a high rate on the emotional exhaustion subscale. Conclusion a moderate level of burnout was identified among the nurses working in a university hospital for the three subscales: emotional exhaustion, depersonalization and personal fulfillment. No significant differences were identified among the burnout mean values and the socio-professional characteristics of the participants, or among the hospital sectors.

Abstract Purpose To evaluate changes in the quantity of elastic fibers in the corpora cavernosa of rats during the natural aging process, and to assess the degree of this change by determining volumetric density (Vv) at different ages via stereological analysis. Methods Forty-eight rats, raised under similar conditions, were subjected to the natural aging process and divided into four groups (G1 to G4), according to age at the time of penectomy (6, 9, 12, and 24 months, respectively). Histological sections of the middle segment of the penis were stained with Weigert’s resorcin-fuchsin, and the volumetric density (Vv) of elastic fibers of the corpora cavernosa were determined via stereological analysis. Results There were no statistically significant differences in Vv among groups G1, G2, and G3. These three groups were therefore considered as a single group. The mean Vv of this group showed a statistically significant reduction compared to that of G4 (0.16 vs. 0.11, p<0.05). Conclusion Natural aging in rats was responsible for a reduction in volumetric density of elastic fibers of the corpora cavernosa (approximately 30% decrease in Vv) during senescence.

Abstract Purpose: To quantify, through stereological and morphometric analysis, spermatogenesis in rats undergoing the natural aging process. Methods: Seventy-two male Wistar rats were divided into 6 equal groups according to age at the time of killing: 3, 6, 9, 12, 18, and 24 months. All the rats were subjected orchiectomy and collection of testicular parenchymal fragments for histological and morphometric analysis. The numerical density of spermatids was calculated using a stereological study, and morphometric analysis was conducted to measure the height of the germinal epithelium and the area of the seminiferous tubules. Results: We found that the 18 and 24 months groups showed a significant reduction in the number of round spermatids. However, the height of the germinal epithelium was not significantly different between the groups. The area of seminiferous tubules was also significantly reduced in the elderly rats compared to that in the young ones. Conclusion: Aging of rats showed a significant reduction in the number of round spermatids and the area of the seminiferous tubules, more pronounced in the rats at 18 and 24 months of life.

ABSTRACT Objectives To describe the retrieval spermatozoa technique for cryopreservation after death, including the proximal part of vas deferens. Material and Methods A 28-years old man, with previous history of infertility, who had died 12 hours before, was submitted to spermatozoa retrieval for cryopreservation, with surgical bilateral resection in bloc of the proximal part of vas deferens, testicle and epididymis. At the laboratory, by milking the epididymis and vas deferens, the extracted fluid was collected; also, three samples of each testicle parenchyma were also harvested. Results The fluid from the vas deferens showed spermatozoa, mostly with in situ motility. Testicular fragments also presented spermatozoa, mostly with small tail movements or immobile. Conclusion The inclusion of the proximal part of vas deferens during spermatozoa retrieval after death must be performed, since it contains high concentration of spermatozoa, and even in the presence of previous infertility, as was with this patient, it is possible to retrieve spermatozoa.

Abstract Purpose: To analyze the effects of aging in rats on the nuclear volume, cytoplasmic volume, and total volume of Leydig cells, as well as their number. Methods: Seventy-two Wistar rats were divided into six subgroups of 12 rats, which underwent right orchiectomy at 3, 6, 9, 12, 18, and 24 months of age. The weight and volume of the resected testicles were assessed. A stereological study of Leydig cells was conducted, which included measurements of cell number and nuclear, cytoplasmic, and total cell volumes. Results: The weight and volume of the resected testicles showed reductions with age. Only the subgroup composed of 24-month old rats showed a decrease in the nuclear volume of Leydig cells. Significant reductions in the cytoplasmic volume and total volume of Leydig cells were observed in 18- and 24-month old rats. The number of Leydig cells did not vary significantly with age. Conclusions: Aging in rats resulted in reduction of the nuclear, cytoplasmic, and total cell volumes of Leydig cells. There was no change in the total number of these cells during aging.

Objective to analyze the characteristics of the nurse’s work environment in a hospital emergency service. Methods a mixed method study with a concurrent triangulation strategy using data from a descriptive-exploratory study, with 19 nurses, and a Grounded Theory study with three sample groups totaling 21 participants. The quantitative data were collected using the Brazilian Nursing Work Index - Revised and were subjected to descriptive statistical analysis. The qualitative data were obtained from interviews and were analyzed through initial and focused coding. Results the nurses considered that they had autonomy, good relationships with the physicians, and organizational support. However, the control over the environment was shown to be an unfavorable characteristic. Based on the results, the category: “Seeking to organize the work environment for demand which exceeds attendance capacity” is presented. Conclusion the characteristics of the emergency environment were shown to be favorable to the nurse’s work, with the exception of control over the environment.

Conclusão as características do ambiente da emergência mostraram-se favoráveis ao trabalho do enfermeiro, exceto o controle sobre o ambiente.

Objectives Evaluation of the presence of spermatozoa in vas deferens fluid after a long interval of unilateral and homolateral percutaneous epididymal sperm aspiration (PESA) in vasectomized men. When found, the spermatozoa were evaluated including concentration and motility, in order to verify the patency of the epididymal tubules. Materials and Methods Four patients, numbered in a progressive order, from one to four, with 38, 40, 48 and 51 years old and vasectomy interval of 10, 10, 25 and 11 years, respectively, whose wives did not get pregnant using intracytoplasmic sperm injection of sperm obtained by unilateral PESA and decided to try only natural conception, were submitted to intrasurgical sperm analysis of the vas deferens fluid (ISAVDF) during microsurgery for reconstruction of the seminal tract. Results Time interval between PESA and ISAVDF was 13.75 ± 11.12 months (x ± s) varying from 3 to 29 months. Homolateral ISAVDF and PESA showed the presence of spermatozoa. Patients 1, 2 and 4 had a high concentration of 10 x 106, 64 x 106 and 45 x 106 spermatozoa/ mL; the first two had motile sperms and patient 3 had no sperms. Conclusions Three of four patients showed spermatozoa in the vas deferens fluid after a long interval of unilateral and homolateral PESA with high concentration, including motile forms. These findings support the concept that PESA may not result in late epipidymal tubule obstruction in vasectomized patients.

OBJETIVO: Determinar se a torção testicular causa efeitos tardios sobre a espermatogênese do testículo contralateral e se a orquiepididimectomia do testículo torcido poderia preveni-los, usando parâmetros específicos da espermatogênese para elucidar os resultados conflitantes na literatura. MÉTODOS: Foram selecionados aleatoriamente 74 ratos machos púberes da linhagem Wistar. O grupo experimental foi composto por 40 ratos divididos em quatro subgrupos, submetidos à torção anti-horária de 1,080 graus do testículo esquerdo e sua fixação escrotal no início do experimento e à orquiepidimectomia esquerda com um, cinco, dez e 90 dias, respectivamente. O grupo controle foi composto por 24 ratos divididos em quatro subgrupos de cirurgias simuladas. Um subgrupo controle adicional foi constituído pelos dez ratos restantes submetidos unicamente à orquiepididimectomia esquerda no início do experimento. Aos 90 dias, os testículos contralaterais dos subgrupos experimentais e controles foram coletados para avaliação dos parâmetros de suas espermatogêneses: peso testicular, diâmetro do túbulo seminífero, graduação de Johnsen e contagem diferencial das células germinativas. RESULTADOS: Não houve diferença estatisticamente significativa entre todos os subgrupos experimentais e controles para todos os parâmetros analisados da espermatogênese dos testículos contralaterais. CONCLUSÕES: A torção testicular não causa efeitos tardios sobre a espermatogênese do testículo contralateral em ratos púberes e a orquiepididimectomia do testículo torcido não é necessária para fins preventivos da espermatogênese contralateral.

PURPOSE: To determine whether the testicular torsion causes long-term effects on the spermatogenesis of the contralateral testis, and whether the orchiepididymectomy of the twisted testis could prevent them, using specific spermatogenesis parameters to elucidate the conflicting results in the literature. METHODS: Seventy-four pubertal male Wistar rats were randomly selected. The experimental group consisted of 40 rats, divided into four subgroups, submitted to 1.080 degrees counterclockwise left testicular torsion and its scrotal fixation at the beginning of the experiment, and left orchiepididymectomy at one, five, ten and 90 days, respectively. The control group consisted of 24 rats, divided into four sham operation control subgroups. An additional control subgroup consisted of the ten remaining rats, submitted only to the left orchiepididymectomy at the beginning. At 90 days, the contralateral testes of the experimental and control subgroups were collected for the evaluation of their spermatogenesis parameters: testicular weight, seminiferous tubular diameter, Johnsen score and differential counting of the germ cells. RESULTS: No statistically significant differences were observed among the experimental and control subgroups for all of the spermatogenesis parameters of the contralateral testes. CONCLUSIONS: Testicular torsion does not cause long-term effects on the spermatogenesis of the contralateral testis in pubertal rats, and the orchiepididymectomy of the twisted testis is not necessary for preventive purposes for the contralateral spermatogenesis.
