OBJECTIVE: To evaluate the natural healing of the rat diaphragm that suffered an extensive right penetrating injury.METHODS: Animals were submitted to an extensive penetrating injury in right diaphragm. The sample consisted of 40 animals. The variables studied were initial weight, weight 21 days after surgery; healing of the diaphragm, non-healing of the diaphragm, and herniated abdominal contents into the chest.RESULTS: Ten animals were used as controls for weight and 30 animals were operated. Two animals died during the experiment, so 28 animals formed the operated group; healing of the diaphragm occurred in 15 animals (54%), 11 other animals showed diaphragmatic hernia (39%) and in two we observed only diaphragmatic injury without hernia (7%). Among the herniated organs, the liver was found in 100% of animals, followed by the omentum in 77%, small bowel in 62%, colon in 46%, stomach in 31% and spleen in 15%. The control group and the diaphragmatic healing subgroup showed increased weight since the beginning of the study and the 21 days after surgery (p <0.001). The unhealed group showed no change in weight (p = 0.228).CONCLUSION: there is a predominance of spontaneous healing in the right diaphragm; animals in which there was no healing of the diaphragm did not gain weight, and the liver was the organ present in 100% the diaphragmatic surface in all rats with healed diaphragm or not.

PURPOSE: To measure the healed areas of osteochondral defects produced in femoral condyles of rabbits filled with biopolymer sugar cane gel and to compare these with those of the control group at 90, 120 and 180 days. METHODS: A study was made of 16 New Zealand rabbits, 6 and 7 months old, weighing between 2 and 2.5 kg. Defects of 3.2 x 4 mm were made, with trephine, in the femoral condyles of the right and left knees. As to the study group defects of the medial and lateral condyles of the right knee were used which were filled with Biopolymer Sugar Cane Gel; as to the Control Group defects of the medial and lateral condyles of the left t knees were used which were left open for natural healing. The defects were analyzed at 90, 120 and 180 days after surgery. After euthanasia, the knees were removed and fixed in Bouin's solution for later digital photographic documentation with a digital camera. The areas healed were measured in both the study and control groups using the images obtained from an Image-J® program. Statistical analysis was conducted using the non-parametric Mann-Whitney test. RESULTS: There were no significant differences between the means of the healed areas in the study and control groups at 90, 120 and 180 days after surgery. CONCLUSION: The dimension of the healed areas of the defects treated with the biopolymer sugar-cane gel in the study group was similar to those of the control group, which healed naturally.

Background. Lumbar hernias are rare abdominal hernias. Surgery is the only treatment option but remains challenging. Posterior incisional hernias are even rarer especially with incarceration of intra-abdominal contents.Case Presentation. A 68-year old female presented with a 3-day history of worsening acute abdominal pain and distension, with multiple episodes of emesis. A CT scan indicated a large incarcerated posterolateral abdominal hernia. The patient had a history of resection of a sarcoma on her back as a child and also received chemotherapy and radiation. During emergency laparoscopy, a hemorrhagic small bowel segment incarcerated in the hernia was reduced and resected, and the distended small bowel was decompressed. An elective hernia repair was scheduled. After temporary clinical improvement, the patient again developed abdominal pain, distention, and emesis. During emergency laparotomy, a large hematoma in the right flank was found and partially evacuated. The right colon was mobilized out of the hernia and the duodenum was kocherized. A20×20cm BIO-A mesh was placed on top of the Gerota fascia and cranially tucked under liver segment VI. Anteriorly, the mesh was fixated with absorbable tacks. The duodenum and colon were placed into the mesh pocket. A postoperative CT scan identified a 2 cm pseudoaneurysm of a side branch of a lumbar artery, and the bleeding source was embolized. The postoperative course was complicated byClostridium difficile-associated colitis, but ultimately, the patient recovered fully. At 6-month follow-up, there was no evidence for a recurrent hernia.Discussion. There is a paucity of literature concerning lumbar incisional hernias. Repair with bioabsorbable mesh seems feasible, but longer follow-up is necessary as the mesh was placed in an unusual fashion due to the retroperitoneal hematoma. The exact cause of the hemorrhage is unclear and may have been caused during the initial incarceration, during surgery, or may be a late complication of her previous radiation.

ObjectiveEvaluate the neurological, neuopsychological and electroencephalogram (EEG) findings in a cohort of retired soccer players.BackgroundChronic traumatic encephalopathy (CTE) is considered to be a consequence of exposure to repeated head traumas, but evidence suggests that a single moderate or severe traumatic brain injury can also induce progressive neuropathological changes.Design/MethodsProspective observational study that evaluated 26 retired soccer players and 14 controls. The retired athletes and controls were submitted to neurological evaluation, neuropsychological evaluation and EEG.ResultsIn general, the soccer players performed well in tests, within the normal range. 15 soccer players had a history of previous TBI/concussion. In the retired group the average age was 60.4 years (55.7 in the CG), average of 11.7 schooling years (13.7 in the CG). The average results in MMSE was 26.6 (29 in the CG), the average digit span in backwards was 3.1 (3.8 in the CG), the average verbal fluency for animals was 15.6 (24 in the CG) and the average clock-drawing test was 8.96 (9 in the CG). Visual EEG analysis showed a predominance of posterior alpha activity between 9.0 and 12.0 Hz (mean 10.3 Hz) in the soccer participants and 11 Hz in the control group (CG). The analysis wiht low resolution electromagnetic tomography (LORETA) showed that 11 soccer players had hippocampal asymmetry (5 had less activity in the right hippocampus and 6 had less activity in the left hippocampus).ConclusionsAlthough the performance of the athletes in the tests was within the normal range, the means were always inferior to those of the controls. Almost half of the players presented asymmetry in the analysis by LORETA, although visual EEG analysis was normal. This may indicate that EEG changes may be earlier and more sensitive than clinical changes. These data are preliminary and further analysis are needed.

The Impact

Objectives: To investigate the impact of having previous history of inversion ankle sprain on balance tests in adolescent volleyball players. Methods: Fourty-five adolescent volleyball players with mean age of 15.26±1.03 participated in our study. Twenty-nine were uninjured (control group) and sixteen had previously experienced inversion injuries on right ankle. 9 players had the injury more than than one year ago and 7 players had it before six to twelf months. Balancing abilities were evaluated by Star Excursion Balance Test (SEBT) and Single Limb Hurdle Test (SLHT). The fact that players with history of injury had the ankle sprain at right foot led us to perform the measurements in the control group also for the right foot. We compared the results of injured and uninjured players on both tests. Results: Uninjured players' reaching distance on right foot was found out to be significantly more than in players with ankle sprain at medial and posteromedial directions of SEBT(p<.05), whereas there were no differences detected for the other directions (p>.05). For comparing athletes' performances with SLHT, finishing time was found significantly better in uninjured players (p<.05). Conclusion: Adolescent volleyball players with history of injury show lower performance on balance tests compared to uninjured players. This demonstrates that they should be given a training including balance and stabilization programs.

Introduction: Noise Induced Hearing Loss (NIHL) is the first cause of acquired hearing loss. Dentists and dental prosthodontics technicians are exposed to different sounds produced by a variety of devices in their occupations. In this study, we studied the effect of dental prosthesis sounds on the auditory power of the respective staff. Methods: This case-control study was carried out among all technicians of dental prosthesis laboratories in Yazd in 2018 selected by census sampling method. A total of 23 technicians who were willing to cooperate and met the inclusion criteria were included in the experimental group. Furthermore,  23 people who referred to the audiology clinic, were matched with the experimental group in terms of age and gender, and were not working in noisy environment, and had no congenital or acquired deafness were examined as the control group.  Finally, the collected data were analyzed by SPSS version 19 using statistical tests. Result: The mean hearing threshold of the right ear at frequencies of 3000 and 4000 Hz and the mean hearing threshold of the left ear at frequencies of 3000, 4000, 6000, and 8000 Hz was significantly higher in the experimental than the control group. The mean hearing threshold of the right ear at the frequency of 4000 Hz and the hearing threshold of the left ear at frequencies of 3000, 4000, and 6000 Hz in participants with job history>4 years was significantly higher. Furthermore, the mean hearing threshold of the right ear in the frequency of 4000 Hz and the hearing threshold of the left ear at frequencies of 3000, 4000, and 6000 Hz years was significantly higher in people with job history >30 years. Conclusion: According to findings, the staffs working in dental prosthodontics laboratories suffer from NIHL at frequencies of 3000 to 8000 Hz. The hearing loss in the left ear was more severe  in  people with job history of >30 years and in people with job history of > 4 years.Therefore, the use of hearing impaired and hearing protectors is recommended in these people.

Aim. To study the diagnostic and prognostic potential of the complex use of ultrasound and 3D laparoscopy in women with pelvic varicose veins (PVV). Outcomes and methods. The study included 100 women who were divided into two groups: the main group (39 patients with various severity PVV) and the control group (61 women with no venous system disorders). All patients had a complete clinical examination with the selection of pairs that had the most significant factors for the disease prognosis: average age over 35 years, history of varicose veins, pain in the lower abdomen, dysmenorrhea and dyspareunia. Examination of the small pelvis venous system included duplex angioscanning and retrograde endoscopic functional test controlled by the three-dimensional image. Multivariate analysis (logistic regression) was used to identify normative phlebological parameters. Results. Predictors of early PVV are the following rations: Vmax in the cava-ovarian segment / Vmax in the right ovary portal ≥ 8.3 and Vmax in the reno-ovarian segment /Vmax in the left ovarian portal ≥ 8. The severity of PVV is determined by a progression of alterations in hemodynamic parameters in the main ovarian veins and a spreading venous congestion in the small pelvis plexuses. Conclusions. Criteria of small pelvis phlebohemodynamics make it possible to predict a development of PVV and a severity of the pathological process. Ovarian varicose veins are characteristic of early PVV and venous plethora of all pelvis venous plexuses is characteristic of late PVV.

Objective: to evaluate natural evolution of right diaphragmatic injury after the surgical removal of a portion from hemi diaphragm. Methods: the animals were submitted to a surgical removal of portion from right hemi diaphragm by median laparotomy. The sample consists of 42 animals being 2 animals from pilot project and 40 operated animals. And the variables of the study were herniation, liver protection, healing, persistent diaphragm injury, evaluation of 16 channels tomography and the variables "heart rate" and "weight". Results: we analyzed 40 mice, we had two post-operative deaths; we had 17 animals in this group suffered from herniation (42.5%) and 23 animals didn't suffer from herniation (57.5%). Analyzing the tomography as image method in the evaluation of diaphragmatic hernia, we had as a method with good sensitivity (78.6%), good specificity (90.9%), and good accuracy (86.1%) when compared to necropsy. Conclusion: there was a predominance of healing of right hemi diaphragm, the size of initial injury didn't have influence on occurrence of the liver protection or hernia in mice.

OBJECTIVE: To evaluate the efficiency of selective hypothermia in the treatment of the traumatic brain injury in rats. METHOD: After the trauma produced for the model of cortical impact, a small craniectomy in the right frontoparietal region was carried through; after the procedure the animals had been divided in two groups of 15 each. Group A, without treatment with hypothermia (control group) and group B, treated with selective hypothermia for a period to 5 to 6 hours. After this time all the animals were sacrificed, their brains had been removed and histopathological analysis was carried through. RESULTS: Comparison between both groups was done using the counting of neurons injured for field. Counting in the control group n=15 had an average of 70.80 neurons injured for field against an average of 21.33 neurons injured for field in group B (submitted to the treatment with hypothermia), with n=15 also. The difference was statiscally significant. CONCLUSION: Based in the quantification of the neurons injured for field, the effectiveness of the treatment with selective hypothermia was demonstrated.
