Lesões Músculo-Esqueléticas em Remadores de Competição

Introduction: The objective of this study was the assessment of the injuries occurred over the competitive rowing lifetime of Portuguese senior rowers. Material and Methods: We sent a questionnaire to all Portuguese senior rowers medalled in the national championships during the 2013-2014 season. We analysed biometric variables, anatomic location, type and circumstances of injury occurrence, type of treatment provided and time of inactivity. For statistical analysis we used parametric and non-parametric statistics with 95% confidence levels (p < 0.05). Results: The questionnaire was answered by 18 of the 18 female and 74 of the 77 male rowers. Females had significantly lower ages, heights and weights and rowed more often sculling boats (p < 0.05). The number of years of practice, as well as the number of injuries per rower was similar, for both females and males. The mean age at the first injury was significantly lower in females (p < 0.001), who also had more progressive lesions than acute ones, although not significantly. In both, the most frequent anatomical location and type of injury were the lumbar region and muscular pathology, with a higher occurrence in winter and spring, during land training. Females sustained longer periods of inactivity, but not significantly. Discussion: The results that were different from those reported by other authors may be related with differences in the studied populations or with other factors that need to be clarified. Conclusion: The injuries sustained by the Portuguese competitive rowers, probably associated with a lower competitive exposure of our athletes, were less severe than those generally reported in the literature.

Objectives: Rugby is sport with a high risk of injury. Repeated changes in exercise intensity and the high training intensity may cause to overuse injuries and long-term disability. The aim of the study was to analyze the prevalence of injuries during trainings and forms of rehabilitation procedures performed after their occurrence among elite and sub-elite rugby players. Methods: The data was obtained from 60 professional rugby males from France and Poland. Data were collected using paper-based recording form. It was a specially designed questionnaire which concerned specific details of the injury, including body location, type of injury, treatment and number of days off lost from playing rugby and on forms of rehabilitation procedures performed after their occurrence among elite and sub-elite rugby players. Results: During the study period, the overall incidence rate for injury suggested a 1.04 times more often injury occurrence (IRR = 1.04, 95% CI: 0.08; 2.00) among Polish players compared with French players; however, the distribution of injuries varied by country. The training injury incidence (TII) and incidence proportion (IP) were also higher in Poland than in France (p < 0.05) with the sprain as the most frequent type of injury in all rugby players. France was 7.8 times (IRR = 7.88, 95% CI: 1.29; 3.21) more likely to sustain a fracture than Poland, which much often experienced less serious injuries (bruise, rapture of muscle and ligament) (IRR = 3.02, 95% CI: 2.06; 3.98). Polish players were provided with various forms of physiotherapy while Franch players often worked with a physiotherapist with a therapeutic method (p < 0.005). Poland and France reported experiencing side effects after an injury and the most frequent was pain. In their opinions, the reasons influencing the effectiveness of rehabilitation are too quick return to the game and too short time of rehabilitation. Conclusions: The competitive level of the rugby player influences not only the frequency and type of injury occurrence, but also access to the different forms of rehabilitation. Nonetheless, the side effects occurring after injury and the causes of ineffective rehabilitation are still similar. Further studies are needed to gather significant data to accurately formulate future injury prevention protocols or recommend modifications to game laws or competition formats, aiming at players’ welfare.

ObjectivesTo determine the injury incidence and characteristics for elite, male, artistic USA gymnasts during gymnastics competitions, held in the USA, from 2008 to 2018.MethodsInjury documentation performed by lead physician and certified athletic trainers at elite junior and senior USA Gymnastics competitions from 2008 to 2018 were reviewed and compiled into an excel database. Injury incidence was computed per 1000 registered gymnasts by competition setting as well as injury location, type, cause, severity, and setting.ResultsFrom 2008 to 2018, 180 injuries were reported in a total of 2102 gymnasts with injury incidence of 85.6 per 1000 gymnasts (95% CI 73.4 to 97.8). The most common injury site was at the ankle (16.7 per 1000 gymnasts, 95% CI 10.9 to 22.4), and muscle strain/rupture/tear was the most common type of injury (28.5 per 1000 gymnasts, 95% CI 21.2 to 35.9). The most common cause was contact with surface (56.1 per 1000 gymnasts, 95% CI 46.1 to 66.2), and the event where most injuries were sustained was the vault (21.9 per 1000 gymnasts, 95% CI 15.4 to 28.4). Incidence of time loss injuries was 38.5 per 1000 gymnasts (95% CI 30.1 to 47.0). Injury incidence was higher during competition (58.5 per 1000 gymnasts, 95% CI 48.2 to 68.8) than during training (27.1 per 1000 RG, 95% CI 19.9 to 34.3; RR 2.16, 95% CI 1.59 to 2.94, p<0.001); injury incidence was greater at Olympic Trials (RR 3.23, 95% CI 1.24 to 8.47, p=0.017) than at National Qualifier meets. We report concussion incidence in gymnastics (5.7 per 1000 gymnasts, 95% CI 2.3 to 9.2).ConclusionsThis is the largest injury study to date for male artistic gymnasts (180 injuries, 2102 gymnasts, 11 years).

Vhl Disease

OBJECT Peritumoral cysts are frequently associated with CNS hemangioblastomas and often underlie neurological morbidity and mortality. To determine their natural history and clinical impact, the authors prospectively analyzed hemangioblastoma-associated peritumoral cysts in patients with von Hippel-Lindau (VHL) disease. METHODS Patients with VHL disease who had 2 or more years of follow-up and who were enrolled in a prospective study at the National Institutes of Health were included. Serial prospectively acquired laboratory, genetic, imaging, and clinical data were analyzed. RESULTS One hundred thirty-two patients (of 225 in the VHL study with at least 2 years of follow-up) had peritumoral cysts that were followed for more than 2 years (total of 292 CNS peritumoral cysts). The mean age at study entrance was 37.4 ± 13.1 years ([mean ± SD], median 37.9, range 12.3–65.1 years). The mean follow-up was 7.0 ± 1.7 years (median 7.3, range 2.1–9.0 years). Over the study period, 121 of the 292 peritumoral cysts (41.4%) became symptomatic. Development of new cysts was associated with a larger number cysts at study enrollment (p = 0.002) and younger age (p < 0.0001). Cyst growth rate was associated with anatomical location (cerebellum cysts grew faster than spine and brainstem cysts; p = 0.0002 and p = 0.0008), younger age (< 35 years of age; p = 0.0006), and development of new neurological symptoms (p < 0.0001). Cyst size at symptom production depended on anatomical location (p < 0.0001; largest to smallest were found, successively, in the cerebellum, spinal cord, and brainstem). The most common location for peritumoral cysts was the cerebellum (184 cysts [63%]; p < 0.0001). CONCLUSIONS Peritumoral cysts frequently underlie symptom formation that requires surgical intervention in patients with VHL disease. Development of new cysts was associated with a larger number of cysts at study enrollment and younger age. Total peritumoral cyst burden was associated with germline partial deletion of the VHL gene.

Purpose: To investigate whether or not the age of spontaneous resolution of monosymptomatic nocturnal enuresis (MNE) was familial. Patients and Methods: A questionnaire was administered to more than 1,500 people, and 100 appropriate participants were identified from four referral hospitals. We included the participants who had MNE and whose parents also had MNE with spontaneous resolution. Then the association between the spontaneous resolution time of MNE in parents and that in their children was investigated. Results: The mean ages of spontaneous resolution were 10.7 (10-30 years), 9.4 (6-17 years) and 10.9 (6-18 years) in participants, their mothers and their fathers, respectively. According to the statistical analysis, there was a positive correlation between participants and both their mothers and fathers (p < 0.05). In addition, it was revealed that familial MNE history based on first- and second-degree relatives, in addition to their parents, was also associated with the increased spontaneous resolution age of MNE (p < 0.05). According to our results, gender and parents' education status were not statistically associated with the spontaneous resolution (p > 0.05). Conclusion: As a conclusion, the age of spontaneous resolution of MNE is familial. Although the exact reasons of spontaneous resolution still remain a mystery; further genetic investigations may be able to resolve this mystery.

The mean length of gestation was 114 days for both gilts and sows.3. The mean numbers of pigs born alive and born dead per litter from gilts, 10·0 and 0·2 respectively, were both significantly smaller than the corresponding figures for sows, 11·8 and O·8. No seasonal differences were found.4. The mean total losses of pigs from birth to weaning at 8 weeks were 29·5% of pigs born alive. The losses in litters from gilts, 23·0%, were significantly smaller than in litters from sows, 31·0%. The losses during the winter months both for gilts, 32·5%, and for sows, 35·9%, were significantly higher than during the summer months, 19·4% and 26·7% for gilts and sows respectively.5. Over 50% of the total losses were due to crushing by the dam, 74·1% of the losses from this cause occurring during the first 48 hr. after birth.6. The mean number of pigs weaned per litter was 8·0. The difference between the number weaned per litter from gilts, 7·7, and per litter from number of pigs was weaned per litter from sows during the summer months, 8·7, than during the winter months, 7·4.7. There was no significant difference between the number of male and of female pigs weaned.8. The mean weight at weaning was 29·9 lb., male pigs, 30·3 lb., being significantly heavier than females, 29·51b. Pigs in litters from gilts, 27·81b., were significantly lighter at weaning than those from sows, 30·0 lb., and for both gilts and sows, pigs reared during the summer months, 29·7 and 31·8 lb. respectively, were significantly heavier than those reared during the winter months, 25·9 and 28·2 lb. respectively.

ABSTRACT Background: Leucopenia has been reported after induction of thiopentone barbiturate therapy for refractory intracranial hypertension. However, the incidence and characterisitics are not well described. Aims: We performed a retrospective review to describe the incidence and characteristics of leucopenia after induction of thiopentone barbiturate therapy. Setting and Design: Our centre is a national referral centre for neurotrauma and surgery in a tertiary medical institution.Materials and Methods: We performed a retrospective review of all patients who received thiopentone barbiturate therapy for refractory intracranial hypertension during an 18 month period from January 2004 to June 2005 in our neurosurgical intensive care unit. Statistical Analysis Used: Statistical analysis was performed using SPSS version 15.0. All data are reported as mean ± standard deviation or median (interquartile range). The Chi square test was used to analyze categorical data and student t test done for comparison of means. For paired data, the paired t?test was used.-test was used. Results: Thirty eight (80.9%) out of 47 patients developed a decrease in white blood cell (WBC) count after induction of thiopentone barbiturate coma. The mean decrease in WBC from baseline to the nadir was 6.4 × 10 9 /L (P <lt; 0.001) and occurred 57 (3-147) h after induction. The mean nadir WBC was 8.6 < 3.6 × 10 9 /L. Three (6.4%) patients were leucopenic, with a WBC count of 2.8, 3.1, and 3.6 < 10 9 /L. None of them were neutropenic. We did not find an association between decrease in WBC count and clinical diagnosis of infection. We did not find any association between possible risk factors such as admission GCS, maximum ICP prior to induction of barbiturate coma, APACHE II score, total duration and dose of thiopentone given, and decrease in WBC count. Conclusions: Decrease in WBC count is common, while development of leucopenia is rare after thiopentone barbiturate coma. Regular monitoring of WBC counts is recommended.

This study evaluated the characteristics and clinical course of patients with iris cysts in the long-term follow-up (24–48 months). We retrospectively analyzed the medical records of 39 patients with iris cysts (27 women and 12 men). Age, visual acuity, intraocular pressure (IOP), slit-lamp evaluation, and ultrasound biomicroscopy images were assessed. The mean age at diagnosis was 40.6 ± 17.48 years. Thirty (76.9%) cysts were peripheral, five (12.8%) were located at the pupillary margin, two (5.1%) were midzonal, and two (5.1%) were multichamber cysts extending from the periphery to the pupillary margin. A total of 23 (59%) cysts were in the lower temporal quadrant, 11 (28.2%) were in the lower nasal quadrant, and 5 (12.8%) were in the upper nasal quadrant. Cyst size was positively correlated with patient age (rs = 0.38, p = 0.003) and negatively correlated with visual acuity (rs = −0.42, p = 0.014). Cyst growth was not observed. The only complication was an increase in IOP in three (7.7%) patients with multiple cysts. The anatomical location of the cysts cannot differentiate them from solid tumors. The vast majority of cysts are asymptomatic, do not increase in size, and do not require treatment during long-term follow-up.

The incidence and the anatomical location of the arcade of Struthers as related to the arm length were studied in 62 arms of adult fresh-frozen cadavers. The distance between the greater tuberosity and the lateral epicondyle was designated as the arm length. The arcades of Struthers were identified in 85.4%. The mean arm length was 27.85 ± 1.3 cm. The mean of the distance between proximal border of the arcade of Struthers and the medial humeral epicondyle was 8.24 ± 2.06 cm. The mean ratio between the distance from the proximal border of the arcade to the tip of the medial epicondyle and arm length was 0.29 ± 0.07. We concluded that the anatomical location of the arcade as related to the arm length was 29% proximally, from the tip of the medial epicondyle. This report of the anatomical location of the arcade of Struthers related to the arm length can be useful to identify this structure in the arms which have differences in arm length during the surgical exploration and anterior transposition of the ulnar nerve procedures.

Background: Studies estimating the Tobacco- specific nitrosamines, (TSNA’s) which are the strongest carcinogens in the saliva oftobacco users and tobacco quitters, are limited.Objectives: To assess and compare the levels of N- nitrosamines (NNN, NNK) in the saliva of tobacco chewers and non -chewers including those who have quit the habit of tobacco use.Methods: The study included 120 patients who were divided into three groups of 40 each: Group I- Smokeless tobacco chewersGroup II- Tobacco chewers who have completely stopped the habit at least 2 weeks prior to sample collection andGroup III- non-chewers. The salivary levels of two tobacco specific nitrosamines; NNN & NNK levels were estimated in the three study groups. Statistical analysis was done by Kruskal– Wallis, one-way analysis of variance (ANOVA) test, Mann-Whitney U test. (p-value < 0.05 was considered to be statistically significant)Results: In Group I, the mean level of NNN was 651.84 ± 359.78 and mean level of NNK was 168.32 ± 131.83. In Group II, the mean level of NNN was 119.52 ± 95.05 and mean level of NNK was 42.78 ± 43.19. In Group III, the mean level of NNN was 3.44 ±6.55 and mean level of NNK was 1.98 ± 3.68. There was a statistical difference in the 3 groups with respect to mean levels of NNN and NNK.Conclusion: The study indicated that salivary tobacco-specific nitrosamines are elevated in tobacco chewers. Saliva can be used to detect TSNA’s and screen for TSNA’s during each patient’s de-addiction process.

Deformation Peak

Background: According to the ventricular myocardial band model, the diastolic isovolumetric period is a contraction phenomenon. Our objective was to employ speckle-tracking echocardiography (STE) to analyze myocardial deformation of the left ventricle (LV) and to confirm if it supports the myocardial band model. Methods: This was a prospective observational study in which 90 healthy volunteers were recruited. We evaluated different types of postsystolic shortening (PSS) from an LV longitudinal strain study. Duration of latest deformation (LD) was calculated as the time from the start of the QRS complex of the ECG to the latest longitudinal deformation peak in the 18 segments of the LV. Results: The mean age of our subjects was 50.3 ± 11.1 years. PSS was observed in 48.4% of the 1620 LV segments studied (19.8%, 13.5%, and 15.1% in the basal, medial, and apical regions, respectively). PSS was more frequent in the basal, medial septal, and apical anteroseptal segments (>50%). LD peaked in the interventricular septum and in the basal segments of the LV. Conclusions: The pattern of PSS and LD revealed by STE suggests there is contraction in the postsystolic phase of the cardiac cycle. The anatomical location of the segments in which this contraction is most frequently observed corresponds to the main path of the ascending component of the myocardial band. This contraction can be attributed to the protodiastolic untwisting of the LV.
