    Full Text Available Abstract Introduction Bilateral rectus femoris haematoma following a simultaneous strain of the quadriceps muscles is a very rare condition. Case presentation We report the case of a 21-year-old Greek Caucasian female rowing athlete who was injured on both thighs. She complained of pain and inability to walk. Physical examination revealed tenderness over the thighs and restriction of knee movement. The result of a roentgenogram was normal, and there was no evidence of fracture or patella displacement. Magnetic resonance imaging revealed haematoma formation in both the rectus femoris muscles. The diameters of the left and right haematomas within the muscles were 6 cm and 5 cm, respectively. Therapeutic approaches included compression bandages, ice application, rest, elevation, and administration of muscle relaxant drugs. Active stretching and isometric exercises were performed after three days. The patient was able to walk using crutches two days after the initiation of treatment. On the seventh day, she had regained her full ability to walk without crutches. Non-steroidal anti-inflammatory drugs were administered on the fifth day and continued for one week. Six weeks later, she had pain-free function and the result of magnetic resonance imaging was normal. She was able to resume her training programme and two weeks later, she returned to her previous sport activities and competitions. Conclusion There are references in the literature regarding the occurrence of unilateral quadriceps haematomas following strain and bilateral quadriceps tendon rupture in athletes. Simultaneous bilateral rectus femoris haematomas after a muscle strain is a rare condition. It must be diagnosed early. The three phases of treatment are rest, knee mobilization, and restoration of quadriceps function.

    Lamellar bone formation in an abnormal location is defined as heterotopic ossification. It commonly occurs around the hip joint and most often involves the abductor muscles. It is a benign condition; however, its etiology remains largely unknown. Most previously reported cases have been due to trauma or intramuscular hemorrhage. In this paper, we present a case of bilateral heterotopic ossification of the reflected head of rectus femoris muscle without antecedent trauma or any other known cau...

    Proximal rectus femoris tendon avulsions are rare and occur mostly in male athletes. Currently, the standard of care for complete tendinous avulsions of the direct arm of the rectus femoris is nonoperative treatment. However, surgical repair may be considered in high-level athletes who have a high demand for repetitive hip flexion performed in an explosive manner or in patients in whom nonoperative treatment has failed. The purpose of this technical note is to describe the method for surgical repair of the proximal direct arm of the rectus femoris to its origin at the anterior inferior iliac spine using suture anchors.

It is a benign condition; however, its etiology remains largely unknown. Most previously reported cases have been due to trauma or intramuscular hemorrhage. In this paper, we present a case of bilateral heterotopic ossification of the reflected head of rectus femoris muscle without antecedent trauma or any other known cause, as the first and unique case in the literature. She was treated by excision of the right symptomatic bony mass via a modified Smith-Petersen approach. Postoperatively, she received 75 mg indomethacin daily for six weeks. She was pain-free and obtained full range of motion 3 weeks after the first intervention.

  5. Magnetic resonance imaging findings after rectus femoris transfer surgery

    International Nuclear Information System (INIS)

    We describe the magnetic resonance (MR) imaging appearance of the knee flexor and extensor tendons after bilateral rectus femoris transfer and hamstring lengthening surgery in five patients (10 limbs) with cerebral palsy. Three-dimensional models of the path of the transferred tendon were constructed in all cases. MR images of the transferred and lengthened tendons were examined and compared with images from ten non-surgical subjects. The models showed that the path of the transferred rectus femoris tendon had a marked angular deviation near the transfer site in all cases. MR imaging demonstrated irregular areas of low signal intensity near the transferred rectus femoris and around the hamstrings in all subjects. Eight of the ten post-surgical limbs showed evidence of fluid near or around the transferred or lengthened tendons. This was not observed in the non-surgical subjects. Thus, MR imaging of patients with cerebral palsy after rectus femoris transfer and hamstring-lengthening surgery shows evidence of signal intensity and contour changes, even several years after surgery.

    The rectus femoris is the most commonly injured muscle of the anterior thigh among athletes, especially soccer players. Although the injury pattern of the muscle belly is well documented, less is known about the anatomy and specific lesions of the proximal tendons. For each head, three distinctive patterns may be encountered according to the location of the injury, which can be at the enthesis, within the tendon, or at the musculotendinous junction. In children, injuries correspond most commonly to avulsion of the anteroinferior iliac spine from the direct head and can lead to subspine impingement. Calcific tendinitis and traumatic tears may be encountered in adults. Recent studies have shown that traumatic injuries of the indirect head may be underdiagnosed and that injuries of both heads may have a surgical issue. Finally, in the case of tears, functional outcome and treatment may vary if the rupture involves one or both tendons and if the tear is partial or complete. Thus, it is mandatory for the radiologist to know the different ultrasound and magnetic resonance imaging (MRI) patterns of these lesions in order to provide accurate diagnosis and treatment. The purpose of this article is to recall the anatomy of the two heads of rectus femoris, describe a reliable method of assessment with ultrasound and MRI and know the main injury patterns, through our own experience and literature review.

    The rectus femoris muscle is the most frequently involved quadriceps muscle in strain pathologies. The majority of quadriceps muscle belly injuries can be successfully treated conservatively and even significant tears in the less active and older population, non-operative management is a reasonable option. The authors report the delayed presentation of a 17-year-old male who sustained an injury to his rectus femoris muscle belly while playing football. This young patient did not recover the functional outcome required to get back to running and participating in sport despite 15 months of physiotherapy and non-operative management. Operative treatment using the ligament augmentation and reconstruction system ligament to augment Kessler repair allowed immediate full passive flexion of the knee and an early graduated physiotherapy programme. Our patient was able to return to running and his previous level of sport without any restrictions.

    2009-01-01

    Rectus femoris transfer is frequently performed to treat stiff-knee gait in subjects with cerebral palsy. In this surgery, the distal tendon is released from the patella and re-attached to one of several sites, such as the sartorius or the iliotibial band. Surgical outcomes vary, and the mechanisms by which the surgery improves knee motion are unclear. The purpose of this study was to clarify the mechanism by which the transferred muscle improves knee flexion by examining three types of trans...

    The spatial distribution pattern of neuromuscular activation within the human rectus femoris (RF) muscle was investigated during gait by multi-channel surface electromyography (surface EMG). Eleven healthy men walked on a treadmill with three gait speeds (4, 5, and 6 km/h) and gradients (0°, 12.5°, and 25°). The spatial distribution of surface EMG was tested by central locus activation (CLA), which is calculated from 2-D multi-channel surface EMG with 46 surface electrodes. For all conditions, CLA was around the middle regions during the swing-to-stance transition and moved in a proximal direction during the stance phase and stance-to-swing transition (pphase significantly moved to proximal site with increasing gait speed (pphases, with increasing grade, CLA significantly moved distally (pgait cycle and is non-uniformly regulated longitudinally.

    2010-11-01

    Quadriceps injuries, ranging from simple strains to disabling muscle ruptures, are common athletic injuries. The rectus femoris is the most commonly injure portion of the quadriceps musculature. This article is, to our knowledge, the first report of a proximal rectus femoris avulsion in an elite, Olympic-level 100-meter sprinter, acutely managed with surgical repair. Several key factors must be considered and carefully assessed when determining the appropriate course of management (ie, deciding between operative and nonoperative treatment): amount of distal retraction of the tendon, severity of associated soft-tissue trauma, physical examination, and postoperative goals (eg, return to elite-level competitive sports involving running or kicking vs resuming basic activities of daily living). We believe that these factors in our elite, high-performance athlete dictated an operative course of management.

    Rectus femoris origin injuries in adult athletes are uncommon. In the acute phase, conservative treatment seems to have a favourable outcome, with surgical repair reserved for unsuccessful cases only. However, a group of patients may develop chronic pain and disability after recovery from the acute phase due to heterotopic calcification occurring at the site of injury. Open and arthroscopic excision of such calcifications has been described in the literature although arthroscopic excision of ...

    ABSTRACT Objective: To evaluate whether distal rectus femoris transfer (DRFT) is related to postoperative increase of knee flexion during the stance phase in cerebral palsy (CP). Methods: The inclusion criteria were Gross Motor Function Classification System (GMFCS) levels I-III, kinematic criteria for stiff-knee gait at baseline, and individuals who underwent orthopaedic surgery and had gait analyses performed before and after intervention. The patients included were divided into the following two groups: NO-DRFT (133 patients), which included patients who underwent orthopaedic surgery without DRFT, and DRFT (83 patients), which included patients who underwent orthopaedic surgery that included DRFT. The primary outcome was to evaluate in each group if minimum knee flexion in stance phase (FMJFA) changed after treatment. Results: The mean FMJFA increased from 13.19° to 16.74° (p=0.003) and from 10.60° to 14.80° (p=0.001) in Groups NO-DRFT and DRFT, respectively. The post-operative FMJFA was similar between groups NO-DRFT and DRFT (p=0.534). The increase of FMJFA during the second exam (from 13.01° to 22.51°) was higher among the GMFCS III patients in the DRFT group (p<0.001). Conclusion: In this study, DRFT did not generate additional increase of knee flexion during stance phase when compared to the control group. Level of Evidence III, Retrospective Comparative Study.

    The purpose of this study was to investigate whether changes in angular velocity would alter vastus lateralis (VL) and rectus femoris (RF) oxygenation status during maximal isokinetic knee extension exercises. Eleven recreationally active male participants randomly performed ten maximal knee extensions at 30, 60, 120 and 240° s(-1). Tissue oxygenation index (TOI) and total haemoglobin concentration ([tHb]) were acquired from the VL and RF muscles by means of near-infrared spectroscopy (NIRS). Breath-by-breath pulmonary oxygen consumption (VO(2p)) was recorded throughout the tests. Peak torque and VO(2p) significantly decreased as a function of velocity (P<0·05). Interestingly, RF and VL TOI significantly increased as a function of velocity (P<0·05), whereas [tHb] significantly decreased as a function of velocity (P<0·05). A greater number of muscle fibre recruited at slow velocity, where the torque and VO(2p) were the highest, might explain the lower VL and RF TOI observed herein. Furthermore, the increase in local blood flow (suggested by [tHb] changes) during isokinetic knee extension exercises performed at slow angular velocity might have been induced by a higher intramuscular pressure during the contraction phases as well as a greater microcirculatory vasodilatation during relaxation phases. Implementing slow-velocity isokinetic exercises in rehabilitation or other training programmes could delay the short-term anoxia generated by such exercises and result in muscle metabolism enhancement.

    Forward dynamic models suggest that muscle-induced joint motions depend on dynamic coupling between body segments. As a result, biarticular muscles may exhibit non-intuitive behavior in which the induced joint motion is opposite to that assumed based on anatomy. Empirical validation of such predictions is important for models to be relied upon to characterize muscle function. In this study, we measured, in vivo, the hip and knee accelerations induced by electrical stimulation of the rectus femoris (RF) and the vastus medialis (VM) at postures representatives of the toe-off and early swing phases of the gait cycle. Seven healthy young subjects were positioned side-lying with their lower limb supported on air bearings while a 90 ms pulse train stimulated each muscle separately or simultaneously. Lower limb kinematics were measured and compared to predictions from a similarly configured dynamic model of the lower limb. We found that both RF and VM, when stimulated independently, accelerated the hip and knee into extension at these postures, consistent with model predictions. Predicted ratios of hip acceleration to knee acceleration were generally within 1 s.d. of average values. In addition, measured responses to simultaneous RF and VM stimulation were within 13% of predictions based on the assumption that joint accelerations induced by activating two muscles simultaneously can be found by adding the joint accelerations induced by activating the same muscles independently. These results provide empirical evidence of the importance of considering dynamic effects when interpreting the role of muscles in generating movement.

    Ultrasonic measurement of the rectus femoris (RF) is a novel, proxy measure for muscle strength. The impact of hip flexion/head of bed positioning on RF cross-sectional area (CSA) has not been fully explored. This study describes and compares differences in RF CSA across four degrees of hip flexion. This repeated-measures, comparative study enrolled healthy, pre-menopausal women (n = 20). RF CSA of the dominant leg was measured using the SonoSite M-Turbo ultrasound system with the head of bed at 0°, 20°, 30°, and 60°. One-way repeated measures indicated significant differences in RF CSA, F(3, 17) = 14.18, p < .001, with variation in hip flexion/head of bed elevation and significant RF CSA differences between: (a) 0° and 20°, (b) 0° and 30°, (c) 0° and 60°, and (d) 20° and 60°. Standardizing patient positioning when conducting ultrasonic measurement of RF CSA is vital for researchers who assess muscle mass.

    Full Text Available Problem statement: It is not well known how local fatigue can impair the contractile properties of skeletal muscle, so the aim of this study was to determine the Tensiomyographic (TMG characteristics of Rectus Femoris (RF after a single bout of intense exercise. Approach: Twelve healthy male volunteers (mean±SEM; age, 24.16±0.62 years, height 172.02±1.21 cm, body mass 71.84±2.19 kg, BMI 24.42±0.70 kg m- were recruited. Results: In session 1, a graded exercise test on cycle ergometer was performed in order to determine subject’s maximal oxygen uptake (VO2max and power at this key point (pVO2max. In a second testing session, TMG rest values were assessed and then all subjects carried out 2 min of cycling at pVO2max after which TMG analysis was applied again. The results showed subject’s VO2max values of 53.44±2.67 ml kg-1 min-1 reaching a mean pVO2max of 270.83±8.61 W. Maximal radial displacement (Dm and time from the onset of electrical stimulus to 10% of Dm (Td were significantly lower at post-test (from 7.577.57±0.92-4.37±0.67 mm; p = 0.01, for Dm and from 25.25±0.57-22.44±0.89 ms; p≤0.05, for Td. Conclusion/Recommendations: It can be concluded that a brief and intense exercise consisting in 2 min of cycling at PVO2max provokes a reduction in contractile properties of RF considering TMG parameters such as Dm and Td. More studies are needed to clarify the role of muscle fatigue on temporal TMG parameters.

    2014-11-01

    Full Text Available Muscle-mass loss augers increased morbidity and mortality in critically ill patients. Muscle-mass loss can be assessed by wide linear-array ultrasound transducers connected to cumbersome, expensive console units. Whether cheaper, hand-carried units equipped with curved-array transducers can be used as alternatives is unknown. Accordingly, our primary aim was to investigate in 15 nondisabled subjects the validity of measurements of rectus femoris cross-sectional area by using a curved-array transducer against a linear-array transducer—the reference-standard technique. In these subjects, we also determined the reliability of measurements obtained by a novice operator versus measurements obtained by an experienced operator. Lastly, the relationship between quadriceps strength and rectus area recorded by two experienced operators with a curved-array transducer was assessed in 17 patients with chronic obstructive pulmonary disease (COPD. In nondisabled subjects, the rectus cross-sectional area measured with the curved-array transducer by the novice and experienced operators was valid (intraclass correlation coefficient [ICC]: 0.98, typical percentage error [%TE]: 3.7% and reliable (ICC: 0.79, %TE: 9.7%. In the subjects with COPD, both reliability (ICC: 0.99 and repeatability (%TE: 7.6% and 9.8% were high. Rectus area was related to quadriceps strength in COPD for both experienced operators (coefficient of determination: 0.67 and 0.70. In conclusion, measurements of rectus femoris cross-sectional area recorded with a curved-array transducer connected to a hand-carried unit are valid, reliable, and reproducible, leading us to contend that this technique is suitable for cross-sectional and longitudinal studies.

    The aim of this study was to evaluate the influence of the Gross Motor Function Classification System (GMFCS) on the outcomes of rectus femoris transfer (RFT) for patients with cerebral palsy and stiff knee gait. We performed a retrospective review of patients seen at our gait laboratory from 1996 to 2013. Inclusion criteria were (i) spastic diplegic cerebral palsy, (ii) GMFCS levels I-III, (iii) reduced peak knee flexion in swing (PKFSwGMFCS levels I and II. In the non-RFT group, no improvement in KROM was observed in any GMFCS level. In this study, patients at GMFCS levels I and II were more likely to benefit from the RFT procedure.

  5. Effects of barbell deadlift training on submaximal motor unit firing rates for the vastus lateralis and rectus femoris.

    Directory of Open Access Journals (Sweden)

    Matt S Stock

    Full Text Available Previous investigations that have studied motor unit firing rates following strength training have been limited to small muscles, isometric training, or interventions involving exercise machines. We examined the effects of ten weeks of supervised barbell deadlift training on motor unit firing rates for the vastus lateralis and rectus femoris during a 50% maximum voluntary contraction (MVC assessment. Twenty-four previously untrained men (mean age  = 24 years were randomly assigned to training (n = 15 or control (n = 9 groups. Before and following the intervention, the subjects performed isometric testing of the right knee extensors while bipolar surface electromyographic signals were detected from the two muscles. The signals were decomposed into their constituent motor unit action potential trains, and motor units that demonstrated accuracy levels less than 92.0% were not considered for analysis. One thousand eight hundred ninety-two and 2,013 motor units were examined for the vastus lateralis and rectus femoris, respectively. Regression analyses were used to determine the linear slope coefficients (pulses per second [pps]/% MVC and y-intercepts (pps of the mean firing rate and firing rate at recruitment versus recruitment threshold relationships. Deadlift training significantly improved knee extensor MVC force (Cohen's d = .70, but did not influence force steadiness. Training had no influence on the slopes and y-intercepts for the mean firing rate and firing rate at recruitment versus recruitment threshold relationships. In agreement with previous cross-sectional comparisons and randomized control trials, our findings do not support the notion that strength training affects the submaximal control of motor units.

    Full Text Available Abstract Background The increasing age of coronary artery disease (CAD patients and the occurrence of sarcopenia in the elderly population accompanied by 'fear of moving' and hospitalization in these patients often results in a substantial loss of skeletal muscle mass and muscle strength. Cardiac rehabilitation can improve exercise tolerance and muscle strength in CAD patients but less data describe eventual morphological muscular changes possibly by more difficult access to imaging techniques. Therefore the aim of this study is to assess and quantify the reliability and validity of an easy applicable method, the ultrasound (US technique, to measure the diameter of rectus femoris muscle in comparison to the muscle dimensions measured with CT scans. Methods 45 older CAD patients without cardiac event during the last 9 months were included in this study. 25 patients were tested twice with ultrasound with a two day interval to assess test-retest reliability and 20 patients were tested twice (once with US and once with CT on the same day to assess the validity of the US technique compared to CT as the gold standard. Isometric and isokinetic muscle testing was performed to test potential zero-order correlations between muscle diameter, muscle volume and muscle force. Results An intraclass correlation coefficient (ICC of 0.97 ((95%CL: 0.92 - 0.99 was found for the test-retest reliability of US and the ICC computed between US and CT was 0.92 (95%CL: 0.81 - 0.97. The absolute difference between both techniques was 0.01 ± 0.12 cm (p = 0.66 resulting in a typical percentage error of 4.4%. Significant zero-order correlations were found between local muscle volume and muscle diameter assessed with CT (r = 0.67, p = 0.001 and assessed with US (r = 0.49, p Conclusions Ultrasound imaging can be used as a valid and reliable measurement tool to assess the rectus femoris muscle diameter in older CAD patients.

    Background. Foam rolling has been shown to acutely increase range of motion (ROM) during knee flexion and hip flexion with the experimenter applying an external force, yet no study to date has measured hip extensibility as a result of foam rolling with controlled knee flexion and hip extension moments. The purpose of this study was to investigate the acute effects of foam rolling on hip extension, knee flexion, and rectus femoris length during the modified Thomas test. Methods. Twenty-three healthy participants (male = 7; female = 16; age = 22 ± 3.3 years; height = 170 ± 9.18 cm; mass = 67.7 ± 14.9 kg) performed two, one-minute bouts of foam rolling applied to the anterior thigh. Hip extension and knee flexion were measured via motion capture before and after the foam rolling intervention, from which rectus femoris length was calculated. Results. Although the increase in hip extension (change = +1.86° (+0.11, +3.61); z(22) = 2.08; p = 0.0372; Pearson's r = 0.43 (0.02, 0.72)) was not due to chance alone, it cannot be said that the observed changes in knee flexion (change = -1.39° (-5.53, +2.75); t(22) = -0.70; p = 0.4933; Cohen's d = - 0.15 (-0.58, 0.29)) or rectus femoris length (change = -0.005 (-0.013, +0.003); t(22) = -1.30; p = 0.2070; Cohen's d = - 0.27 (-0.70, 0.16)) were not due to chance alone. Conclusions. Although a small change in hip extension was observed, no changes in knee flexion or rectus femoris length were observed. From these data, it appears unlikely that foam rolling applied to the anterior thigh will improve passive hip extension and knee flexion ROM, especially if performed in combination with a dynamic stretching protocol.

    [Purpose] The purpose of this study was to examine range of motion (ROM) and the muscle activity of stroke patients during obstacle task on the ground and underwater. [Subjects] The subjects of this study were seven stroke patients in a hospital located in Daejeon, South Korea. [Methods] The measurements in this study were conducted in an exercise therapy room and a pool dedicated to underwater exercise (water temperature 33.5 °C, air temperature 27 °C) in the hospital building. The pool's water depth was determined by considering the levels of the xiphoid process of the study subjects. Ten-centimeter-high obstacles were used. An electrogoniometer was used to examine the ROM of flexion and extension of the hip joints on the affected side. An MP150 system a BioNomadix 2-channel wireless EMG transmitter was used to examine the muscle activity of the rectus femoris and biceps femoris of the affected side. [Conclusion] The results suggest that the unaffected side was supported, that the affected side moved, and that the hip joint was bent more underwater than on the ground. The rectus femoris and bicpes femoris were activated significantly less underwater than on the ground in all sections.

    The word "Locomotive syndrome" has been proposed to describe the state of requiring care by musculoskeletal disorders and its high-risk condition. Reduction of the knee extension strength is cited as one of the risk factors, and the accurate measurement of the strength is needed for the evaluation. The measurement of knee extension strength using a dynamometer is one of the most direct and quantitative methods. This study aims to develop a system for measuring the knee extension strength using the ultrasound images of the rectus femoris muscles obtained with non-invasive ultrasonic diagnostic equipment. First, we extract the muscle area from the ultrasound images and determine the image features, such as the thickness of the muscle. We combine these features and physical features, such as the patient's height, and build a regression model of the knee extension strength from training data. We have developed a system for estimating the knee extension strength by applying the regression model to the features obtained from test data. Using the test data of 168 cases, correlation coefficient value between the measured values and estimated values was 0.82. This result suggests that this system can estimate knee extension strength with high accuracy.

    This study sought to compare the myoelectric activity of the hip adductors (HAs) and rectus femoris (RF) when the hip was in a neutral position or externally rotated by 30° or 50° (H0, H30, and H50, respectively) during a parallel squat. Ten healthy subjects performed 10 repetitions of squats in each of the 3 hip positions and the myoelectric activities of the HAs and RF were recorded. The signal was then divided into categories representing concentric (C) and eccentric (E) contractions in the following ranges of motion: 0-30° (C1 and E1), 30-60° (C2 and E2), and 60-90° (C3 and E3) of knee flexion. From those signals, an root mean square (RMS) value for each range of motion in each hip position was obtained. All values were normalized to those obtained during maximum voluntary isometric contraction. We found that HAs showed a significant increase in myoelectric activity during C3 and E3 in the H30 and H50 positions, as compared with H0. Meanwhile, RF activity did not significantly differ between hip positions. Both muscles showed higher activation during 60-90° (C3 and E3) of knee flexion, as compared with 0-30° (C1 and E1) and 30-60° (C2 and E2). The results suggest that if the aim is to increase HA activity despite the low percentage of muscle activation, squats should be performed with 30° of external rotation and at least 90° of knee flexion.

    Background and Purpose To report on the outcomes of treating children with a persistent esotropia with an injection of botulinum toxin in a medial rectus muscle. Patients and Methods The medical records of all children at one institution with a persistent esotropia after bilateral medial rectus recessions and bilateral lateral rectus resections who were then treated with a botulinum toxin injection were reviewed. Results Five patients with a mean preoperative esotropia of 37 PD (range, 25-50 PD) underwent bilateral medial rectus recessions and then bilateral lateral rectus resections. Their residual esotropia (mean, 25 PD; range, 18-35) was then treated with a single injection of 3- 5 units of botulinum toxin into one medial rectus muscle. The patients were then followed for a mean of 34 months (range, 14 to 79 months). At last follow-up, 2 patients had an esotropia <10 PD. The other 3 patients had no long-term improvement in their ocular alignment. Two of these patients then underwent additional strabismus surgery. In both cases, they then developed a consecutive exotropia. Conclusion Treatment with a single injection of botulinum toxin was beneficial in 2 of 5 children. Botulinum toxin treatment alone did not result in a consecutive exotropia in any patients treated. PMID:24260804

    Background: Calcific deposits in tendon, muscles, and periarticular areas are very common. Heterotopic ossification of the rectus femoris (HORF) is a rare condition, and several theories exist regarding the etiopathogenesis, which appears to be multifactorial with traumatic, genetic, and local metabolic factors involved. Although HORF typically responds to nonoperative treatment, when this approach fails, endoscopic treatment is a minimally invasive technique to address the pathology. Purpose: To report the clinical and radiological outcomes of 9 athletes with HORF who underwent endoscopic resection. Study Design: Case series; Level of evidence, 4. Methods: Nine male athletes were treated with endoscopic extra-articular resection of HORF after failure of a 6-month course of nonoperative treatment. All patients were studied with radiographs, computed tomography, and magnetic resonance imaging. Outcomes were assessed clinically using the modified Harris Hip Score (mHHS), a visual analog scale for sport activity–related pain (VAS-SRP), patient satisfaction, and ability and time to return to the preoperative sport level. Radiographic assessment was performed to determine recurrence. Results: The mean age of the patients was 32 years (range, 23-47 years). Mean follow-up was 44 months (range, 14-73 months). All patients had improved mHHS scores from a mean preoperative of 65.6 (SD, 8.2) to 93.9 (SD, 3.6). Pain decreased from a mean 8.2 preoperatively (SD, 0.9) to 0.4 (SD, 0.7) at last follow-up. There were no complications, and all patients were able to return to their previous sports at the same level except for 1 recreational athlete. There was only 1 radiological recurrence at last follow-up in an asymptomatic patient. Conclusion: To our knowledge, this is the largest case series of athletes with HORF treated with endoscopic resection. We found this extra-articular endoscopic technique to be safe and effective, showing clinical outcome improvement and 90% chance of

    Validity and intratester reliability of two test methods designed to identify stretchability of the rectus femoris muscle (RFM) was investigated, combined with x-ray analysis of pelvic tilt in the sagittal plane. The first method is commonly used in clinical practice. The second is a new technique supposed to tilt the pelvis posteriorly and thus further separate the origin and insertion of the muscle. Investigation of validity and intratester reliability of the two methods was made by testing and retesting a random sample of 71 persons. The tests were performed with an equipment that automatically recorded the angle of knee flexion from a previously determined applied torque, indicating the end point of motion for that particular subject. Angle of knee flexion and subjective estimation of pain sensation due to stretch were recorded at each measurement. The pelvic tilt-analysis consisted of test-retest reliability of x-ray measurements, comparison between the methods in both starting and final position, and x-ray and electronic goniometer measurements. All applied torques were measured with a strain gauge. Two out of three criteria of validity favored the new method and the third pointed out the two methods as equal. The two methods as well as the x-ray measurements showed high reliability, and the hypothesis of a more posterior tilted pelvis in the new method was confirmed. The electronic goniometer was less sensitive than x-ray, but proposed to analyse pelvic tilt clinically. Methodology procedures for joint angle measurements are discussed.

    The purpose of this study was to compare long-term outcomes of multi-level surgery with and without rectus femoris transfer (RFT) in a group of children with cerebral palsy. Forty-one subjects with a diagnosis of cerebral palsy were divided into a RFT group (28 subjects with 50 sides) and non-RFT group (13 subjects with 22 sides). The study protocol included pre-operative gait analysis, multi-level orthopedic surgical intervention, one year post-operative gait analysis, and three year or greater post-operative gait analysis. All participants received inpatient physical therapy for 2-12 weeks either following surgery or following a period of immobilization, depending on surgical procedures performed. Results showed improved peak knee flexion during swing phase (PKFS) for the RFT group one year after surgery. The deviation from normal in PKFS in the RFT group improved, on average, from seven to five degrees. The deviation from normal in PKFS in the non-RFT group increased approximately four degrees in the same period of time. The knee flexion swing range (KFSR) of the RFT group increased dramatically by 11 degrees after surgery, where no significant KFSR changes observed in the non-RFT group. Those parameters maintained relatively stable from one to three years post surgery for both groups. These observations support our hypothesis that improvements after RFT surgery persist over time, counteracting the negative effects of growth and time.

Hindlimb suspension in group UN was performed for 2 weeks, and then release the suspension for another 2 weeks (group RL) . The changes in protein expression of rectus femoris were analyzed by 2D electrophoresis. Results As compared with the group C, we found 21 different expressions of proteins in group UL, among which contractile protein levels of myosin light chain 1 (MLC1) , myosin regulatory light chain 2,tropomyosin α, b-chain, a-actin and MLC3 increased. Creatine kinase, and αB-crystallin returned to the control levels in group RL. Conclusion Muscle atrophy in group UL probably was caused by the changes in catabolic enzymes of myofibrilla and in enzymes of metabolic regulation.

    Abstract Background: Robotic cholecystectomy (RC) using port sites in the lower abdominal area (T12-L1) rather than the upper abdomen has recently been introduced as an alternative procedure for laparoscopic cholecystectomy. Therefore, we investigated the time course of different components of pain and the analgesic effect of the bilateral ultrasound-guided split injection technique for rectus sheath block (sRSB) after RC in female patients. Methods: We randomly assigned 40 patients to undergo ultrasound-guided sRSB (RSB group, n = 20) or to not undergo any block (control group, n = 20). Pain was subdivided into 3 components: superficial wound pain, deep abdominal pain, and referred shoulder pain, which were evaluated with a numeric rating scale (from 0 to 10) at baseline (time of awakening) and at 1, 6, 9, and 24 hours postoperatively. Consumption of fentanyl and general satisfaction were also evaluated 1 hour (before discharge from the postanesthesia care unit) and 24 hours postoperatively (end of study). Results: Superficial wound pain was predominant only at awakening, and after postoperative 1 hour in the control group. Bilateral ultrasound-guided sRSB significantly decreased superficial pain after RC (P < 0.01) and resulted in a better satisfaction score (P < 0.05) 1 hour after RC in the RSB group compared with the control group. The cumulative postoperative consumption of fentanyl at 6, 9, and 24 hours was not significantly different between groups. Conclusions: After RC with lower abdominal ports, superficial wound pain predominates over deep intra-abdominal pain and shoulder pain only at the time of awakening. Afterwards, superficial and deep pain decreased to insignificant levels in 6 hours. Bilateral ultrasound-guided sRSB was effective only during the first hour. This limited benefit should be balanced against the time and risks entailed in performing RSB. PMID:27495072

    Full Text Available Purpose: To evaluate the efficiency of medial rectus advancement surgery in consecutive exotropia. Material and Methods: The study group consisted of 20 cases, 10 male, 10 female, who were diagnosed as consecutive exotropia and underwent surgery between 2008-2013 at Cukurova University Medical Faculty Ophthalmology Department. Records of the patients were investigated retrospectively. We evaluated best corrected visual acuity, existence of ambliopia, postoperative duration following the first surgery and applied surgical procedures. Postoperative deviation lower than 10 PD were assesed as successful. Mean follow up period was 29,8 +/- 21,36 (8-80 months, patients with inadequate follow up period were dismissed from the study group. Results: We only applied bilateral medial rectus advancement surgery to 6 and unilateral medial rectus advancement surgery to 5 patients and obtained intended surgical result in these 11 cases. The other patients underwent lateral rectus recession or/and medial rectus resection operations inorder to reach projected deviation degrees. Deviation was found to be 46,4+/-9,24 (40-70 PD in cases who only underwent advancement surgery and was 65,56 +/- 18,78 (40-90 PD in cases who underwent additional surgical procedure. 16 (%80 of the cases had hypermetropi various dioptries and 7 (%35 had ambliopia. Discussion: Consecutive exotropia can appear years after surgery and is an important late period complication. In this study achievement of %55 success with medial rectus advancement surgery indicates that this is a preferable procedure. But in wide angle deviations additional lateral rectus recession or/and medial rectus resection operations can be applied inorder to reach intended adjustment. Accurrate prediction of the propotion of advancement surgery and adjustment is not always possible because of intensive fybrosis in operated muscles and enviroment tissue.

    Full Text Available Migration of silicone explants through rectus muscle insertion is a rare complication with very few casesreported. Anterior migration of a solid silicone band may occur if it is tight, placed anterior to the equatoror not properly anchored to the sclera. The band slowly erodes through the tendon of one or more rectimuscles allowing them to reattach spontaneously with scar tissue behind migrating element. The authorsdescribe a rare case of anterior migration of the buckle following encirclage by a 4mm silicone bandresulting in spontaneous disinsertion of medial rectus muscle where muscle disinsertion had not beenperformed peroperatively. This migration occurred in the absence of any predisposing factors. The muscledisinsertion was so gradual that the muscle got reinserted almost to its original insertion as a result ofwhich there was no heterotropia .

    Force enhancement during and following muscle stretch has been observed for electrically and voluntarily activated human muscle. However, especially for voluntary contractions, the latter observation has only been made for adductor pollicis and the ankle joint muscles, but not for large muscles like quadriceps femoris. Therefore, the aim of this study was to investigate the effects of active muscle stretch on force production for maximal voluntary contractions of in vivo human quadriceps femoris (n = 15). Peak torques during and torques at the end of stretch, torques following stretch, and passive torques following muscle deactivation were compared to the isometric torques at corresponding muscle length. In addition, muscle activation of rectus femoris, vastus medialis and vastus lateralis was obtained using surface EMG. Stretches with different amplitudes (15, 25 and 35 degrees at a velocity of 60 degrees s(-1)) were performed on the plateau region and the descending limb of the force-length relation in a random order. Data analysis showed four main results: (1) peak torques did not occur at the end of the stretch, but torques at the end of the stretch exceeded the corresponding isometric torque; (2) there was no significant force enhancement following muscle stretch, but a small significant passive force enhancement persisted for all stretch conditions; (3) forces during and following stretch were independent of stretch amplitude; (4) muscle activation during and following muscle stretch was significantly reduced. In conclusion, although our results showed passive force enhancement, we could not provide direct evidence that there is active force enhancement in voluntarily activated human quadriceps femoris.

  2. THE EFFECT OF GENDER AND FATIGUE ON THE BIOMECHANICS OF BILATERAL LANDINGS FROM A JUMP: PEAK VALUES

    2007-03-01

    Full Text Available Female athletes are substantially more susceptible than males to suffer acute non-contact anterior cruciate ligament injury. A limited number of studies have identified possible biomechanical risk factors that differ between genders. The effect of fatigue on the biomechanics of landing has also been inadequately investigated. The objective of the study was to examine the effect of gender and fatigue on peak values of biomechanical variables during landing from a jump. Thirty-two recreational athletes performed bilateral drop jump landings from a 40 cm platform. Kinetic, kinematic and electromyographic data were collected before and after a functional fatigue protocol. Females landed with 9° greater peak knee valgus (p = 0.001 and 140% greater maximum vertical ground reaction forces (p = 0.003 normalized to body weight compared to males. Fatigue increased peak foot abduction by 1.7° (p = 0.042, peak rectus femoris activity by 27% (p = 0.018, and peak vertical ground reaction force (p = 0.038 by 20%. The results of the study suggest that landing with increased peak knee valgus and vertical ground reaction force may contribute to increased risk for knee injury in females. Fatigue caused significant but small changes on some biomechanical variables. Anterior cruciate ligament injury prevention programs should focus on implementing strategies to effectively teach females to control knee valgus and ground reaction force

    The objectives were to examine knee angle-, and gender-specific knee extensor torque output and quadriceps femoris (QF) muscle recruitment during maximal effort, voluntary contractions. Fourteen young adult men and 15 young adult women performed three isometric maximal voluntary contractions (MVC), in a random order, with the knee at 0 degrees (terminal extension), 10 degrees, 30 degrees, 50 degrees, 70 degrees, and 90 degrees flexion. Knee extensor peak torque (PT), and average torque (AT) were expressed in absolute (N m), relative (N m kg(-1)) and allometric-modeled (N m kg(-n)) units. Vastus medialis (VM), vastus lateralis (VL), and rectus femoris (RF) muscle EMG signals were full-wave rectified and integrated over the middle 3 s of each contraction, averaged over the three trials at each knee angle, and normalized to the activity recorded at 0 degrees. Muscle recruitment efficiency was calculated as the ratio of the normalized EMG of each muscle to the allometric-modeled average torque (normalized to the values at 0 degrees flexion), and expressed as a percent. Men generated significantly greater knee extensor PT and AT than women in absolute, relative and allometric-modeled units. Absolute and relative PT and AT were significantly highest at 70 degrees, while allometric-modeled values were observed to increase significantly across knee joint angles 10-90 degrees. VM EMG was significantly greater than the VL and RF muscles across all angles, and followed a similar pattern to absolute knee extensor torque. Recruitment efficiency improved across knee joint angles 10-90 degrees and was highest for the VL muscle. VM recruitment efficiency improved more than the VL and RF muscles across 70-90 degrees flexion. The findings demonstrate angle-, and gender-specific responses of knee extensor torque to maximal-effort contractions, while superficial QF muscle recruitment was most efficient at 90 degrees, and less dependent on gender.

    Objective Vertical rectus transposition (VRT) is used to treat abduction limitation, but new vertical deviations and anterior segment ischemia are concerns. Johnston and Crouch described superior rectus transposition (SRT), a procedure in which only the superior rectus muscle is transposed temporally. We describe our results using augmented temporal SRT with adjustable medial rectus muscle recession (MRc) for treatment of Duane syndrome I (DS) and sixth nerve palsy. Methods Retrospective surgical case review of patients undergoing the SRT procedure. Pre- and post-operative orthoptic measurements were recorded. Minimum follow-up was 6 weeks. Main outcome measures included angle of esotropia in primary position and the angle of head turn. Secondary outcomes included duction limitation, stereopsis, and new vertical deviations. Results The review identified seventeen patients (10 with DS and 7 with sixth nerve palsy). SRT+MRc improved esotropia [from 44 PD to 10.1 PD (p< 0.0001)], reduced abduction limitation [from −4.3 to −2.7 (p<0.0001)] and improved compensatory head posture [from 28°to 4° (p<0.0001)]. Stereopsis was recovered in eight patients (p=0.03). Three patients required a reoperation; one for overcorrection and 2 for undercorrection. A new primary position vertical deviation was observed in 2/7 patients with complex sixth nerve palsy and 0/10 DS patients. No patient described torsional diplopia. Conclusions SRT allows for the option of simultaneous medial rectus recession in patients with severe abduction imitation who require transposition surgery. SRT+MRc improved esotropia, head position, abduction limitation, and stereopsis without inducing torsional diplopia. PMID:22332212

    This study examined the rectus abdominis myofascial flap as an innervated nap for dynamic cardiomyoplastic purposes. It is common to use the latissimus dorsi to wrap or patch around or in the heart, but there is a need for more innervated skeletal muscle for a variety of reasons. The rectus abdomini

    The M. quadriceps femoris from USDA Choice (n = 12) and USDA Select (n = 12) carcasses were fabricated traditionally (COLD) or innovatively (HOT), in which the seams it shares with the top round and bottom round were separated prerigor to evaluate positional and locational effects on Warner-Bratzler shear force (WBSF), sensory attributes, and objective color. At slaughter, paired USDA Choice and USDA Select carcasses were alternately assigned either the HOT or COLD treatment. At 48 h postslaughter, subprimals were removed, vacuum-packaged, and aged for an additional 5 d. After aging, the M. quadriceps femoris was cut into 2.54-cm-thick steaks and allowed to bloom 1 h. For the M. rectus femoris (REC) and M. vastus lateralis (VAL), L* values significantly (P moving from the proximal to distal position within the muscle. Similarly, a* and b* values decreased in the VAL when moving from the proximal to the distal aspect. After color measurement, steaks were vacuum-packaged and frozen (-26 degrees C) until shear and sensory data were collected. Significant position (proximal to distal) and location effects (cranial to caudal) were noted for both muscles. However, treatment did not affect WBSF of the VAL. Although intramuscular variation existed, WBSF and sensory panel tenderness ratings were acceptable for the REC. Although WBSF values were greater and tenderness ratings were less than the REC, the VAL were not extremely tough and therefore could be used in enhancement applications. PMID:18539844

    Full Text Available The aim of this study was to investigate whether the limbus-insertion distance (LID of the lateral rectus (LR muscle can be a useful indicator for predicting the surgical effect of recession surgery in intermittent exotropia (IXT. Patients who underwent unilateral or bilateral LR recession for the basic type of IXT were included. The distance between the corneal limbus and the posterior edge of the insertion of LR muscle (limbus-insertion distance was measured intraoperatively using surgical calipers (graded with 0.25 mm precision. We calculated the actual dose-response effect as the difference between the angle of preoperative deviation and the angle of postoperative deviation, and then divided the figure by the total amount of recession at postoperative months 1, 3, and 6. The correlation between the limbus-insertion distance (LID of LR muscle and each dose-response effect was statistically analyzed. A total of 60 subjects were enrolled in this study. The mean LID of LR muscle was 5.8±0.7 mm. The dose-response effect was 3.2±1.0 prism diopters (PD/mm at postoperative month 1, 3.4±1.0 PD/mm at postoperative month 3, and 3.4±1.1 PD/mm at postoperative month 6. The LID of the LR muscle was significantly correlated with dose-response effects in cases of unilateral and bilateral LR recession at postoperative months 3 and 6 (P = 0.01, <0.01, 0.04 and <0.01 respectively. As the LID of the LR muscle increased by 1 mm, the dose-response effect increased by 0.2PD/mm in unilateral LR recession, and by 0.4 PD/mm in bilateral LR recession at postoperative month 6. In conclusion, the LID of the LR muscle can be used as one predictor of the recession effect to assist in surgical planning for IXT. Moreover, undercorrection at the time of LR recession might be considered in patients with long LID of the LR muscle.

    2010-05-01

    Full Text Available Abstract An alcoholic 50-year-old male patient with a history of schizophrenia sustained stab wounds into both ventricles and left lung, and survived following an emergency department thoracotomy. The EDT wound, however became infected requiring serial debridements of soft tissue, rib cartilage and sternum. Regional flap options such as pectoralis major and latissimus dorsi muscle flaps could not be employed due to inadequate reach of these flaps. Additionally, bilateral transection of the internal mammary arteries during emergency thoracotomy eliminated the use of rectus abdominis muscles as pedicled flaps based on the superior epigastric vasculature. Therefore, the EDT wound was reconstructed by using the right rectus abdominis muscle as a free flap. The deep inferior epigastric vessels of the flap were anastomosed to the right internal mammary vessels proximal to their transection level in the third-forth intercostal space. The flap healed with no further wound complications.

    Full Text Available Background and Objective: Campylobacter rectus is considered as one of the bacterial species of etiological importance in periodontitis. Iron-containing proteins such as transferrin are found in periodontal sites and may serve as a source of iron for periodontopathogens. The aim of this study was to investigate the capacity of C. rectus to assimilate transferrin-bound iron to support its growth. Design: Growth studies were performed in broth media pretreated with an iron-chelating resin and supplemented with various iron sources. The uptake of iron by C. rectus was monitored using 55Fe-transferrin. Transferrin-binding activity was assessed using a microplate assay while the degradation of transferrin and iron removal was evaluated by polyacrylamide gel electrophoresis. A colorimetric assay was used to determine ferric reductase activity. Results: Holotransferrin (iron-saturated form but not apotransferrin (iron-free form was found to support growth of C. rectus in an iron-restricted culture medium. Incubation of holotransferrin with cells of C. rectus resulted in removal of iron from the protein. A time dependent intracellular uptake of iron by C. rectus cells from 55Fe-transferrin was demonstrated. This uptake was significantly increased when bacteria were grown under an iron-limiting condition. Cells of C. rectus did not show transferrin-binding activity or proteolytic activity toward transferrin. However, a surface-associated ferric reductase activity was demonstrated. Conclusion: To survive and multiply in periodontal sites, periodontopathogens must possess efficient iron-scavenging mechanisms. In this study, we showed the capacity of C. rectus to assimilate iron from transferrin to support its growth. The uptake of iron appears to be dependent on a ferric reductive pathway.

    This study was performed to obtain evidence regarding bilateral hindrance of motor unit (MU) recruitment in the quadriceps femoris (QF) of patients with anterior cruciate ligament (ACL) reconstruction. The subjects included 70 patients who underwent ACL reconstruction and 35 healthy subjects. To identify the muscle torque per unit volume (MTPUV), the peak torque of each velocity of isokinetic performance was divided by muscle volume of the QF measured by a series of cross-sectional images obtained by magnetic resonance imaging scans. Tests revealed that the mean MTPUV of the uninjured (0.113+/-0.03 N m/cm3 at 60 degrees /s, 0.081+/-0.02 N m/cm3 at 180 degrees /s) and injured sides (0.109+/-0.03 N m/cm3 at 60 degrees /s, 0.079+/-0.023 N m/cm3 at 180 degrees /s) were significantly lower than those of the control group (0.144+/-0.05 N m/cm3 at 60 degrees /s, 0.096+/-0.04 N m/cm3 at 180 degrees /s). Previous studies suggested that MU recruitment in the QF of patients with ACL injury was hindered bilaterally. However, the design of their studies could not provide evidence of bilateral hindrance of MU recruitment in the QF. The results of the present study demonstrated that the MTPUV of both injured and uninjured sides of patients were significantly lower than those of the control group.

    Full Text Available Muscle variation may occur due to genetic or developmental causes. Some variations may compromise the vascular, muscular or nervous system in the region. Bilateral muscle variation in popliteal fossa is very rare. In present study an instance of bilateral muscle variation in popliteal fossa, arising from different muscles like gastrocnemius and from biceps femoris is recorded. There is no report of such variations. These observations are rare of its kind because of bilateral asymmetrical presence and difference in the origins in different legs. This is the first report as for the literatures available. Clinical and functional importance of such variation is discussed with the morphological aspects of this anomalous muscle.

    Full Text Available Pyomyositis is a primary bacterial infection of striated muscles nearly always caused by Staphylococcus aureus. Development of the intramuscular abscess involving the extra-ocular muscles (EOMs remains an extremely rare process. We herein present a case of isolated EOM pyomyositis involving superior rectus muscle in a 2-year male child who was referred with complaints of swelling in left eye (LE and inability to open LE since last 1-month. Orbital computed tomography (CT scan showed a well-defined, hypo-dense, peripheral rim-enhancing lesion in relation to left superior rectus muscle suggestive of left superior rectus abscess. The abscess was drained through skin approach. We concluded that pyomyositis of EOM should be considered in any patient presenting with acute onset of orbital inflammation and characteristic CT or magnetic resonance imaging features. Management consists of incision and drainage coupled with antibiotic therapy.

    Full Text Available Introduction: Epiphyseal dysplasia of the femoral head (EDFH is defined as an alteration in the development of the child’s hip, characterized by delayed ossification of the proximal femoral epiphysis. Methods: Herein, we present six cases of epiphyseal dysplasia of the femoral head (EDFH, seen by the principal author (EVA within the last six years with minimum follow up at 15 months. Results: The cases were all diagnosed as casual findings. None of the children had symptoms or clinical signs in the hip, only one had a history of hip pain for five days, two months prior, which was diagnosed at the time as transient synovitis. Discussion: Among the differential diagnoses, the main one is Perthes disease, which is differentiated by several parameters like earlier age onset for EDFH (in children below 4 years of age, bilateralism (50% vs. 10%, and a calmer presentation in Meyer’s dysplasia. The evolution in Meyer’s dysplasia is toward improving radiographic changes. None of the patients revealed incongruence of the hip or early degenerative changes, indicating an excellent prognosis. Many authors think it is a variant of the normal ossification of the femoral head.

    Female athletes are substantially more susceptible than males to suffer acute non-contact anterior cruciate ligament injury. A limited number of studies have identified possible biomechanical risk factors that differ between genders. The effect of fatigue on the biomechanics of landing has also been inadequately investigated. The objective of the study was to examine the effect of gender and fatigue on peak values of biomechanical variables during landing from a jump. Thirty-two recreational athletes performed bilateral drop jump landings from a 40 cm platform. Kinetic, kinematic and electromyographic data were collected before and after a functional fatigue protocol. Females landed with 9° greater peak knee valgus (p = 0.001) and 140% greater maximum vertical ground reaction forces (p = 0.003) normalized to body weight compared to males. Fatigue increased peak foot abduction by 1.7° (p = 0.042), peak rectus femoris activity by 27% (p = 0.018), and peak vertical ground reaction force (p = 0.038) by 20%. The results of the study suggest that landing with increased peak knee valgus and vertical ground reaction force may contribute to increased risk for knee injury in females. Fatigue caused significant but small changes on some biomechanical variables. Anterior cruciate ligament injury prevention programs should focus on implementing strategies to effectively teach females to control knee valgus and ground reaction force. Key pointsFemale athletes landed with increased knee valgus and VGRF which may predispose them to ACL injury.Fatigue elicited a similar response in male and female athletes.The effectiveness of sports injury prevention programs may improve by focusing on teaching females to land softer and with less knee valgus.

    The purpose of this study was to determine whether the muscle architecture of each head of the quadriceps femoris (QF) at multiple regions can be used to predict knee extension force. Muscle thickness and pennation angle were measured using sonographic images from multiple regions on each muscle of the QF with the knee flexed to 90°. The fascicle lengths of the rectus femoris (RF), vastus lateralis (VL) and vastus intermedius (VI) muscles were estimated based on sonographic images taken along the length of the thigh. The muscle architecture of the vastus intermedius was determined in two separate locations using sonographic images of the anterior (ant-VI) and lateral portions (lat-VI). The maximal voluntary contraction (MVC) was measured during isometric knee extension at a knee joint angle of 90°. The relationship between MVC force and muscle architecture was examined using a stepwise linear regression analysis with MVC force as the dependent variable. The muscle thickness of the ant-VI was selected as an independent variable in the first step of the linear regression analysis (R(2) = 0.66, P<0.01). In the second step, pennation angle of the lat-VI was added to the model (R(2) = 0.91, P<0.01). These results suggest that among the four muscles that make up the QF, the muscle architecture of the VI is the best predictor of knee extension force.

  1. A case misdiagnosed as bilateral abducens palsy

    International Nuclear Information System (INIS)

    A 66-year-old male was admitted to our neurosurgical floor because of double vision and gait disturbance. Neurological examinations revealed bilateral 6th nerve palsy with both eyes pointing toward the midline. Initially, using a tentative diagnosis of intracranial mass lesions, especially localized at the base of the skull, computerized tomography of the head, cerebral angiography, orbital venography, and metrizamide CT cisternography were performed; the findings were normal. An orbital CT scan showed an enlargement of the bilateral medial rectus muscles, and the thyroid functions of T3 and T4 and the T3 uptake were all elevated, which was compatible with the diagnosis of Graves' disease. The limitations of both eyeballs were considered to be due not to the 6th nerve palsy, but to the hypertrophy of the bilateral medial rectus muscles. We neurosurgeons should recall Graves' disease as well as intracranial lesions, cerebrovascular disease, and post-traumatic sequelae when examining a patient who presents limitations of external ocular movement.

    Konishi, Y U

    2011-04-01

    The purpose of this study was to investigate the effect of surgery on the gamma-loop in the quadriceps of patients with ACL injuries. We compared the response to vibration stimulation in subjects with ACL repair, subjects with ACL rupture, and normal subjects, by measuring the maximal strength and integrated electromyography (I-EMG) of the quadriceps. Pre-vibration data were obtained from each subject by measuring the MVC of the knee extension and the I-EMG from the vastus medialis, vastus lateralis, and rectus femoris. Vibration stimulation was applied to the infrapatellar tendon, followed immediately by repeating maximal strength and I-EMG recording. The results of this study indicated that alpha motor neuron activity of the intact side of the vastus lateralis in response to prolonged vibration stimulation was altered by surgery, but no effect was detected in the injured side. The results could suggest that abnormality of the gamma-loop existed even in the quadriceps of patients with ACL rupture since the vibration stimulus failed to elicit changes in ACL-rupture group as compared with those of normal subjects. In comparison, abnormality of the gamma-loop in the intact side of the QF was probably induced by the rupture, and further abnormality of gamma-loop was induced by surgery.

    A 44-year-old man was referred to our department with diplopia, periorbital swelling and haematoma of the left eye after orbital trauma due to a punch. During the examination, mild enophthalmos, hypertropia and a total absence of infraduction were observed. An orbital computed tomography (CT) scan demonstrated a left orbital floor blow-out fracture, with caudal herniation of periorbital fat and rectus inferior muscle. Repair was performed under total anaesthesia with placement of a Titan mesh. The following days were marked by the persistence of diplopia without improvement of infraduction. A postoperative, 0.5 mm CT scan highlighted a complete rupture of the inferior rectus muscle, not seen before operation, by a 1.0 mm-sliced CT. In this case, orthoptic therapy was undertaken with good results after 6 months and without need of a second repair. PMID:24963904

    Sixteen patients with moderate angle esotropia of 30 to 35 prism dioptres were treated with a unilateral medial rectus muscle recession of 6 or 6.5 mm. Thirteen of sixteen patients (80%) were straight postoperatively or had 12 prism dioptres or less of esotropia. Three of the 16 had greater than 12 prism dioptres of esotropia, and none were exotropic. This procedure should be considered as an alternative approach in the treatment of moderate angle esotropia.

    Full Text Available Introduction. Skeletal muscle atrophy is a common adaptation after major muscle lesion of m. biceps femoris that results in numerous health-sport related complications. Resistance strength training and whole-body vibration (WBV have been recognized as an effective tool, which attenuates atrophy and evokes hypertrophy. Case report. We presented a 13-year-old boy with a lesion of m. biceps femoris and posttraumatic calcification sustained in soccer training session 6 month prior participation in this study. The patient underwent training 3 times a week for 7 weeks, including unilateral progressive WBV + resistance training (RT of the right hamstrings muscle group using WBV and weights. Hamstrings muscle strength was measured using a Cybex isokinetic dynamometer. At the end of week 4, the patient peak torque value of the involved leg increased from 39% body weight (BW to 72% BW and bilateral deficit decreased from -64% to -35%; at the end of week 7 the participant’s peak torque value of the involved leg increased from 72% BW to 98% BW and bilateral deficit decreased from -35% to -3%, respectively. Conclusion. Unilateral WBV + RT protocol evokes strength increase in the hamstrings muscle group. This case study suggests that adding WBV, as well as the RT program have to be considered in the total management of strength disbalance. Further studies are needed to verify the efficiency of WBV + RT protocol over the classic physical therapy exercise program.

    A 44-year-old woman with no medical history presented with a 1-year history of horizontal diplopia, bilateral exophthalmos and progressive asymmetrical ophthalmoparesis, with no pupillary dysfunction or ptosis. Within 3 months of her initial presentation, she noticed paresis of right eye abduction, followed after 1 month with paresis of left eye abduction. Initial investigations revealed positive antiperoxidase antibodies for Graves' disease and positive AChR for myasthenia gravis. MRI of the brain showed increased intensity in bilateral inferior rectus muscles and CT of the chest showed thymic hyperplasia. Treatment with carbimazole and pyridostigmine was started, with complete resolution after 1 month.

    Full Text Available Clivus fractures are a rare pathology, frecuently associated tohigh power trauma. Such injuries may be associated with vascular and cranial nerves lesions. The abducens nerve is particularly vulnerable to traumatic injuries due to its long intracranial course, since their real origin until the lateral rectus muscle. The unilateral abducens nerve palsy of 1- 2-7% occurs in patients with cranial trauma, bilateral paralysis is rare. We report a patient who presented bilateral abducens nerve palsy associated with a clivus fracture

    In order to investigate a correlation between morphological variations of the biceps femoris muscle and its homologues in four primate species (Japanese macaque, spider monkey, white-handed gibbon, and chimpanzee) and each type of species-specific locomotor behavior, I carried out both morphological and functional analyses of these muscles. The description of the level of insertion reveals interspecific variation is in the level of crural attachment, especially in species with a bicipital biceps femoris muscle. Electromyograms (EMGs) were induced from both the long and short head of the biceps femoris muscle during four kinds of locomotor behavior (horizontal quadrupedal walking, climbing on an inclined pole, vertical climbing, and bipedal walking). In the case of the monoceptual ischiocruralis lateralis muscle of the Japanese macaque, EMGs were induced from both the one-joint femoral part and the two-joint crural part. Though during horizontal quadrupedal locomotion the crural part of the monocipital-type muscle functioned to maintain the knee joint angle, it functioned to gain propulsive force when the kinematic load became larger, as in vertical climbing and bipedal walking. On the other hand, the long heads of the biceps femoris muscles were active in propulsion regardless of the kinematic load. But in bipedal walking, the long head muscle also acted with the short head muscle to maintain the knee joint angle. These functional features of various biceps femoris muscles of primates correlated with their species-specific locomotor behavior. PMID:2504047

    A 48-year-old smoker with a history of hyperthyroidism treated 10 years prior to presentation with radioactive iodine ablation of the thyroid gland presented to his ophthalmologist with a 2-week history of transient loss of vision in the right eye occurring for 1 to 2 hours each morning. He denied ocular pain, diplopia or change in the prominence of one or both eyes. Examination revealed 2 mm of relative proptosis on the right, bilateral temporal flare and lower lid retraction. There was minimal upper lid retraction and no evidence of lid lag. Ocular motility was full. Dilated fundoscopic examination revealed bilateral optic nerve edema, right more than left. CT of the orbit demonstrated enlargement of the extraocular muscles bilaterally with marked enlargement of the right medial rectus and left inferior rectus muscles resulting in crowding at the orbital apex bilaterally. Laboratory testing revealed the patient to be hyperthyroid. The patient was treated with high dose oral steroids followed by orbital radiation. Hyperthyroidism was managed by the patient's primary care physician. Visual symptoms rapidly improved with oral steroids and orbital radiation. Optic nerve edema completely resolved. Repeat CT imaging demonstrated a reduction in the enlargement of the extraocular muscles with relief of bilateral optic nerve compression.

    Full Text Available Ventrodorsal pelvic radiographs were made of 32 adult dogs under general anaesthesia. The hip joints were evaluated according to the severity of osteoarthritic changes graded as 0, 1, 2 or 3. The dogs were euthanased, the hip joints opened and the ligamentum capitis femoris dissected out in toto. The volume of each ligament was determined using a water displacement technique and the mean volume compared to the four radiographic grades of osteoarthritis. There was an inverse correlation (r = -0.75 between the mean volume of the ligamentum capitis femoris and the increasing severity of osteoarthritis as assessed by radiography. The results confirmed the crucial role of radiography in the clinical evaluation of hip dysplasia and osteoarthritis in the adult dog. Assessment of the volume of the ligamentum capitis femoris revealed that it is an important tool for research in canine hip dysplasia and osteoarthritis.

    Purpose: To determine the distribution of the toxin among individual muscles after intramuscular injection of botulinum toxin gel.Methods: One eye of 7 New Zealand white rabbits was randomized into group A, and the contralateral eye was into group B. Eyes in group A received medial rectus intramuscular injection of 2.5 IU of 125I-BTX-A gel in 0.1 ml, and those in group B received equivalent amount of 125I-BTX-A solution by medial rectus intramuscular injection. Four rectus muscles and the levator palpebrae superioris were harvested and the radioactivity of muscles was measured 16 hours after the injection.Results: In group A, the radioactivity of per gram medial rectus was significantly higher than that of other muscles (P < 0.01), and there was no statistically significant difference in the radioactivity of per gram muscles among other muscles (P > 0.05). In group B, the radioactivity of per gram medial rectus and levator palpebrae superioris was significantly higher than that of other muscles respectively(P < 0.05), and the difference in the radioactivity of per gram muscles between medial rectus and levator palpebrae superioris was not statistically significant (P > 0.05). The radioactivity of per gram medial rectus in group A was higher than that in group B (t=3.731 ,P=0.01), and there was no significant difference in the radioactivity of per gram muscles among other homonymous muscles (P > 0.05).Conclusion: The toxin dispersed principally in the injected muscle and the local concentration of the toxin was much high following intramuscular injection of botulinum toxin gel.

    1990-01-01

    The purpose of this study was to compare the effects of biofeedback-facilitated exercise with exercise alone on the recovery rate of quadriceps femoris muscle function following anterior cruciate ligament (ACL) reconstruction. Functional measures included 1) a dynamometric test of quadriceps femoris muscle isometric peak torque during the 12th postoperative week and 2) the number of days post-operatively that a patient achieved full active extension of the knee. Twenty-two patients with acute ACL injury were randomly assigned to a Treatment (biofeedback) Group (n = 11) or a Control (nonfeedback) Group (n = 11) during the first therapy session one week after reconstructive surgery. After the patients had completed the 12-week exercise program, the quadriceps femoris muscle isometric peak torque in the operative limb was compared with that in the nonoperative limb at three angles (90 degrees, 60 degrees, and 45 degrees) of extension. An analysis of variance revealed significant differences between the Treatment and Control Groups at all three angles. Mean recovery time was calculated for each group, and a t test for independent samples indicated a significant difference between the groups. These results demonstrate that the addition of biofeedback to muscle strengthening exercises facilitates the rate of recovery of quadriceps femoris muscle function following ACL reconstruction.

    In Jeong Lyu

    Full Text Available We evaluate the surgical outcomes and surgical responses of medial rectus muscle (MR recession patients with thyroid eye disease (TED-related esotropia (ET. The surgical dose-response curves 1 week postoperatively and at the final visit were analyzed. Univariable and multivariable linear regression analyses were applied to investigate factors influencing surgical dose-response. A total of 43 patients with TED-related ET that underwent MR recession were included. The final success rate was 86.0% and the rate of undercorrection was 14.0%. The surgical dose-response curves of TED-related ET showed a gentle slope compared with those of standard surgical tables. In the univariable model, simultaneous vertical rectus muscle recession was the only significant factor influencing surgical dose-response of MR recession in TED-related ET (β = -0.397, P = 0.044. In a model adjusted for age, sex, type of surgery, and preoperative horizontal angle of deviation, simultaneous vertical rectus muscle recession showed marginal significance (β = -0.389, P = 0.064. The surgical dose-response curve of TED-related ET was unique. Simultaneous vertical rectus muscle recession was associated with increased surgical dose-response in TED-related ET.

    In case of complex anal fistulae, the treatment can include muscular flaps. The gracilis transposition flap is the gold-standard in perineal reconstructive surgery, with wide use during the past decades. However, in some cases, this flap is too short to reach difficult locations such as the posterior perineum. The long head of the biceps femoris, which has already been studied in the electrically stimulated neosphincter formation, could be more appropriate in such clinical situations. Furthermore, its potential advantages, amongst which an excellent functional outcome, would be to allow persistent prone position, during both treatment and reconstruction, as well as a more favorable intramuscular vascularisation. We report the case of a 39-year-old man with a complex recurrent transphincteric posterior anal fistula with an external orifice in the right buttock and complicated with a severe cellulitis, treated with an endo-anal flap combined with a long head of biceps femoris pediculised flap.

    Ultrasonic velocity was used to characterise the differences in composition and texture of Biceps Femoris muscles from four batches of pigs of different genetics (Iberian and Iberian × Duroc) and feeding systems ("montanera" and concentrate). Significant differences (p<0.05) were found for the ultrasonic velocity in samples with different genetics and feeding systems. These differences were dependent on the temperature of the measurements and were related to the intramuscular fat content (IMF) of the samples and, therefore, to the meat quality. The ultrasonic velocities at 0 and 20 °C were related to the IMF (R=0.77 and 0.65, respectively). A discriminant analysis, including ultrasonic velocity at temperatures from 0 to 20 °C, allowed 87.0% of the samples to be correctly classified in the batches. Therefore, ultrasonics could be useful in the characterisation and differentiation of B. femoris muscles of Iberian pigs with different genetics and from different feeding systems.

    A 37-year-old man presented to the acute knee and sports medicine clinic with atraumatic lateral knee pain. He had point tenderness over the lateral aspect of his knee which had not settled with anti-inflammatory medications. Imaging revealed a large opaque lesion lateral to the knee and although there was no clear mechanism, injury to the posterolateral corner was considered. An MRI subsequently revealed a rare case of calcific tendinitis to the biceps femoris tendon insertion. This condition was self-limiting and did not require interventions such as steroid injections. This is the first reported case of calcific tendinitis of biceps femoris as a cause of acute knee pain. PMID:27473032

    We report a rare case of bilateral orbital metastases as the presentation in a 63-year-old woman. Biopsy of a diffusely infiltrated medial rectus muscle suggested metastatic adenocarcinoma. Investigation revealed a palpable mass of the right breast not shown on mammography or sonography. Invasive lobular carcinoma was found at core-needle biopsy with histological features identical to those of the orbital lesion. Metastases to the extraocular muscles are uncommon, particularly as the initial abnormality in the absence of disseminated disease. (orig.)

    The myodural bridge was first described by Hack in 1995 and was thought to be related to chronic cervicogenic headaches. For a long time, few studies revealed the patterns of the myodural bridge considering the rectus capitis posterior minor muscle. In this study, P45 plastination technology and anatomical dissection were performed on head specimens, and four different terminal region types of the rectus capitis posterior minor muscle were observed, including the posterior atlanto-occipital interspace, posterior arch of the atlas and posterior atlanto-axial interspace. We propose that the myodural complex structures in the posterior atlanto-occipital and posterior atlanto-axial interspace have cooperative effects on cerebrospinal fluid and work together. This force might be an important source for the circulation of cerebrospinal fluid. PMID:25859757

  18. Mechanical characterisation of porcine rectus sheath under uniaxial and biaxial tension.

    2014-06-03

    Incisional hernia development is a significant complication after laparoscopic abdominal surgery. Intra-abdominal pressure (IAP) is known to initiate the extrusion of intestines through the abdominal wall, but there is limited data on the mechanics of IAP generation and the structural properties of rectus sheath. This paper presents an explanation of the mechanics of IAP development, a study of the uniaxial and biaxial tensile properties of porcine rectus sheath, and a simple computational investigation of the tissue. Analysis using Laplace׳s law showed a circumferential stress in the abdominal wall of approx. 1.1MPa due to an IAP of 11kPa, commonly seen during coughing. Uniaxial and biaxial tensile tests were conducted on samples of porcine rectus sheath to characterise the stress-stretch responses of the tissue. Under uniaxial tension, fibre direction samples failed on average at a stress of 4.5MPa at a stretch of 1.07 while cross-fibre samples failed at a stress of 1.6MPa under a stretch of 1.29. Under equi-biaxial tension, failure occurred at 1.6MPa with the fibre direction stretching to only 1.02 while the cross-fibre direction stretched to 1.13. Uniaxial and biaxial stress-stretch plots are presented allowing detailed modelling of the tissue either in silico or in a surrogate material. An FeBio computational model of the tissue is presented using a combination of an Ogden and an exponential power law model to represent the matrix and fibres respectively. The structural properties of porcine rectus sheath have been characterised and add to the small set of human data in the literature with which it may be possible to develop methods to reduce the incidence of incisional hernia development.

    Insertional tendinopathy of the adductors and rectus abdominis is common in male athletes, especially in soccer players. It may be worsened by physical activity and it usually limits sport performance. The management goal in the acute phase consists of analgesic and anti-inflammatory drugs and physical rehabilitation. In the early stages of rehabilitation, strengthening exercises of adductors and abdominal muscles, such as postural exercises, have been suggested. In the sub-acute phase, muscu...

  20. Soccer attenuates the asymmetry of rectus abdominis muscle observed in non-athletes.

    Fernando Idoate

    Full Text Available PURPOSE: To determine the volume and degree of asymmetry of the rectus abdominis muscle (RA in professional soccer players. METHODS: The volume of the RA was determined using magnetic resonance imaging (MRI in 15 professional male soccer players and 6 non-active male control subjects. RESULTS: Soccer players had 26% greater RA volume than controls (P<0.05, due to hypertrophy of both the dominant (28% greater volume, P<0.05 and non-dominant (25% greater volume, P<0.01 sides, after adjusting for age, length of the RA muscle and body mass index (BMI as covariates. Total volume of the dominant side was similar to the contralateral in soccer players (P = 0.42 and in controls (P = 0.75 (Dominant/non-dominant = 0.99, in both groups. Segmental analysis showed a progressive increase in the degree of side-to-side asymmetry from the first lumbar disc to the pubic symphysis in soccer players (r = 0.80, P<0.05 and in controls (r = 0.75, P<0.05. The slope of the relationship was lower in soccer players, although this trend was not statistically significant (P = 0.14. CONCLUSIONS: Professional soccer is associated with marked hypertrophy of the rectus abdominis muscle, which achieves a volume that is 26% greater than in non-active controls. Soccer induces the hypertrophy of the non-dominant side in proximal regions and the dominant side in regions closer to pubic symphysis, which attenuates the pattern of asymmetry of rectus abdominis observed in non-active population. It remains to be determined whether the hypertrophy of rectus abdominis in soccer players modifies the risk of injury.

    Full Text Available PURPOSE: To determine the volume and degree of asymmetry of the musculus rectus abdominis (RA in professional tennis players. METHODS: The volume of the RA was determined using magnetic resonance imaging (MRI in 8 professional male tennis players and 6 non-active male control subjects. RESULTS: Tennis players had 58% greater RA volume than controls (P = 0.01, due to hypertrophy of both the dominant (34% greater volume, P = 0.02 and non-dominant (82% greater volume, P = 0.01 sides, after accounting for age, the length of the RA muscle and body mass index (BMI as covariates. In tennis players, there was a marked asymmetry in the development of the RA, which volume was 35% greater in the non-dominant compared to the dominant side (P<0.001. In contrast, no side-to-side difference in RA volume was observed in the controls (P = 0.75. The degree of side-to-side asymmetry increased linearly from the first lumbar disc to the pubic symphysis (r = 0.97, P<0.001. CONCLUSIONS: Professional tennis is associated with marked hypertrophy of the musculus rectus abdominis, which achieves a volume that is 58% greater than in non-active controls. Rectus abdominis hypertrophy is more marked in the non-dominant than in the dominant side, particularly in the more distal regions. Our study supports the concept that humans can differentially recruit both rectus abdominis but also the upper and lower regions of each muscle. It remains to be determined if this disequilibrium raises the risk of injury.

Some muscle injuries, such as those located in the adductor longus, a monoarticular muscle, as well as rectus abdominis do not fully comply with these requirements. This study examines five cases of elite handball players with ruptured rectus abdominals. Sonographically, lesions in rectus abdominis are shown as a disruption of the fibrillar pattern with a hematic suffusion that invades the entire lesion. In some of the cases, the ultrasound study was complemented with a MRI. A unified rehabilitation protocol was applied and the return to play time of each handball player ranged between 16 and 22 days, with an average of 18.2 days. Follow-up at 15 months showed no evidence of re-injury or residual discomfort and all of them are playing at their highest level.

    A better understanding of the abdominal wall biomechanics could help designing new treatments for incisional hernia. In the current study, a new experimental protocol was developed to evaluate the contributions of the abdominal wall components to the mechanical response of the anterior part of the abdominal wall. The specimens underwent 3 dissections (removal of 1: skin and subcutaneous fat, 2: anterior rectus sheath, 3: rectus abdominis muscles). After each dissection, they were subjected to...

    Abdominal muscles participate in generating a large number of behaviors and reflex responses, including expiration, coughing, sneezing, vomiting, postural control, production of speech, straining, facilitation of venous return to the heart, and reaction to vestibular stimulation. However, the only premotor neurons that have been conclusively shown to influence abdominal motoneurons are located in nucleus retroambiguus, the expiratory region of the caudal ventral respiratory group. In the present study, the neural circuitry controlling the activity of one abdominal muscle, rectus abdominis, was mapped using the transneuronal tracer pseudorabies virus (PRV) in the ferret. Injections of PRV into rectus abdominis labeled large presumed motoneurons in the ventral horn of T12-L4, and smaller presumed interneurons that were scattered in laminae VII, VIII, IX, and X of T4-L4. In addition, neurons in several areas of the medulla and caudal pons, including the retroambigual nucleus, medial and ventromedial reticular formation, nucleus prepositus hypoglossi, vestibular nuclei, and raphe nuclei, were infected by transynaptic passage of PRV from rectus abdominis motoneurons. Thus, the multifunctional roles of abdominal muscles appear to be coordinated by premotor neurons located in both the spinal cord and several regions of the brainstem. PMID:10023028

    A 67 year old woman presented with her left eye fixed in adduction and infraduction. She had previous complicated strabismus surgery 18 years ago with a report of intraoperative loss of left medial rectus (MR) muscle (not retrieved at the time of surgery). An Orbital MRI of the left eye showed reattachment of the MR muscle to the globe and an axially enlarged globe associated with inferior displacement of the lateral rectus and nasal displacement of the superior rectus muscles. In ultrasonography the axial lengths were 24.1 mm in the right and 29.9 mm in the left eye. She underwent staged surgery: The first stage was a recession of the left MR muscle and union procedure on the SR and LR muscles followed by a second adjustable suture procedure under topical anesthesia, of right MR recession, right LR resection and left IR recession. After 12 months her eyes were still binocularly aligned. Unilateral high myopia must be considered in progressive esotropia. Imaging and ultrasonography can demonstrate anatomical abnormality and muscle paths to confirm the definite diagnosis. Union procedure described by Yokoyama is an effective procedure in correcting this strabismus associated with high myopia. PMID:23822915

Thus,preoperative evaluation of rectus abdominis muscle and abdominal subcutaneous fat tissue isimportant. This is a retrospective study that measured the thickness of rectus abdominis muscleand abdominal subcutaneous fat tissue using computed tomography (CT and analyzed thecorrelation with the patients’ age, gestational history, history of laparotomy, and body massindex (BMI.Methods A total of 545 adult women were studied. Rectus abdominis muscle and abdominalsubcutaneous fat thicknesses were measured with abdominopelvic CT. The results were analyzedto determine if the thickness of the rectus abdominis muscle or subcutaneous fat tissue wassignificantly correlated with age, number of pregnancies, history of laparotomy, and BMI.Results Rectus abdominis muscle thicknesses were 9.58 mm (right and 9.73 mm (left at thexiphoid level and 10.26 mm (right and 10.26 mm (left at the umbilicus level. Subcutaneousfat thicknesses were 24.31 mm (right and 23.39 mm (left. Rectus abdominismuscle thicknessdecreased with age and pregnancy. History of laparotomy had a significant negative correlationwith rectus abdominis muscle thickness at the xiphoid level. Abdominal subcutaneous fatthickness had no correlation with age, number of pregnancies, or history of laparotomy.Conclusions Age, gestational history, and history of laparotomy influenced rectus abdominismuscle thickness but did not influence abdominal subcutaneous fat thickness. These results areclinically valuable for planning a rectus abdominis muscle flap and safe elevation of muscle flap.

    This study examined the use of ultrasound to monitor changes in the long head of the biceps femoris (BF) architecture of aprofessional soccer player with acute first-time hamstring strain. The player followed a 14 session physiotherapy treatment until return to sport. The pennation angle and aponeurosis strain of the long head of the biceps femoris (BF) were monitored at 6 occasions (up until 1 year) after injury. The size of the scar / hematoma was reduced by 63.56% (length) and 67.9% (width) after the intervention and it was almost non-traceable one year after injury. The pennation angle of the fascicles underneath the scar showed a decline of 51.4% at the end of the intervention while an increase of 109.2% of the fascicles which were closer to deep aponeurosis was observed. In contrast, pennation angle of fascicles located away from the injury site were relatively unaffected. The treatment intervention resulted in a 57.9% to 77.3% decline of maximum strain per unit of MVC moment and remained similar one year after the intervention. This study provided an example of the potential use of ultrasound-based parameters to link the mechanical adaptations of the injured muscle to specific therapeutic intervention. Key pointsChanges in fascicle orientation after biceps femoris mild tear were reduced after a 28 day intervention and remained similar one year after injury.Tendon/aponeurosis strain per unit of moment of force decreased during the course of the therapeutic intervention.Future studies could utilize ultrasonography to monitor mechanical responses after various types of hamstring injury and interventions in order to improve criteria for a safe return to sport.

    Osteomas are the most common benign osteoclastic tumours of the paranasal sinuses. However, nasal cavity and turbinate osteomas are extremely rare. Only nine middle turbinate, three inferior turbinate and one inferior turbinate osteoma cases have been reported to date. The present case report describes the management and follow-up of symptomatic bilateral inferior turbinate osteoma. A 60-year-old female presented with symptoms of bilateral nasal obstruction and right-sided epiphora. Radiological investigation found hypertrophic bony changes involving both inferior turbinates. The patient was managed successfully by endoscopic inferior turbinectomies in order to achieve a patent airway, with no further recurrence of tumour after 3 months postoperatively. To the best of our knowledge, this is the first reported case of bilateral inferior turbinate osteoma. We describe a safe and minimally invasive method of tumour resection, which has a better cosmetic outcome compared with other approaches. PMID:27534890

    We report the case of a 50-year-old paraplegic man with a complicated grade III/IV ischiatic pressure sore treated with a propeller flap based on the first perforator of the profunda femoris artery. Our aim was to surgically reconstruct an ischiatic pressure sore in a patient with ankylosis using a fasciocutaneous perforator propeller flap obtained from the posterior region of the thigh. Our decision to perform a profunda femoris artery perforator propeller flap reconstruction was mainly due to the anatomical contiguity of the flap with the site of the lesion and the good quality of the skin harvested from the posterior region of the thigh. The use of the perforator fasciocutaneous flap represents a muscle-sparing technique, providing a better long-term result in surgical reconstruction. The choice of the 180-degree propeller flap was due to its ability to provide a good repair of the pressure ulcer and to pass over the ischiatic prominence in the patient in the forced decubitus position. The operatory course did not present any kind of complication. Using this reconstructive treatment, we have obtained complete coverage of the ischiatic pressure sore. PMID:26495200

    2014-09-01

    Full Text Available Introduction: Very little attention has been paid to muscle architecture in the Sub-Saharan African environment, and the rectus abdominis muscle, being a stabilising agent in the trunk, should not be left out. Considering the incidence of trunk musculoskeletal discomfort, it is necessary to assess the rectus abdominis muscle. Aim of the research: To assess the thickness of the rectus abdominis muscle in an apparently healthy adult population using ultrasound and to evaluate its possible relationship with important anthropometric variables. Material and methods : A total of 120 healthy subjects made up of 60 males and 60 females, who gave their written consent, were recruited for this study. B-mode ultrasound was used to assess the rectus abdominis muscle. Anthropometric variables were also assessed. Results: The results show that the rectus abdominis thickness (RAT was 14.68 ±2.92 mm and 14.37 ±2.74 mm for the right (RRAT and left (LRAT sides, respectively. The males had significantly thicker muscles than the females (p = 0.004 and the RAT correlated positively with age, weight, height, body mass index, body surface area, waist circumference, and conicity index. Conclusions: These results show robust myoanthropometric relationships that will assist surgeons in reconstructive procedures involving the muscle. They will also serve as a guidepost in the biomechanical assessment of the muscle in lifting sports for an African population, in the study of muscle flaps, and in the general evaluation of trunk mass.

    2013-01-01

    Full Text Available Background If a chronically infected abdominal wound develops, complications such asperitonitis and an abdominal wall defect could occur. This could prolong the patient’s hospitalstay and increase the possibility of re-operation or another infection as well. For this reason,a solution for infection control is necessary. In this study, surgery using a rectus abdominismuscle myofascial splitting flap was performed on an abdominal wall defect.Methods From 2009 to 2012, 5 patients who underwent surgery due to ovarian rupture,cesarean section, or uterine myoma were chosen. In each case, during the first week afteroperation, the wound showed signs of infection. Surgery was chosen because the wounds didnot resolve with dressing. Debridement was performed along the previous operation woundand dissection of the skin was performed to separate the skin and subcutaneous tissue fromthe attenuated rectus muscle and Scarpa’s fascial layers. Once the anterior rectus sheath andmuscle were adequately mobilized, the fascia and muscle flap were advanced medially sothat the skin defect could be covered for reconstruction.Results Upon 3-week follow-up after a rectus abdominis myofascial splitting flap operation,no major complication occurred. In addition, all of the patients showed satisfaction in termsof function and esthetics at 3 to 6 months post-surgery.Conclusions Using a rectus abdominis myofascial splitting flap has many esthetic andfunctional benefits over previous methods of abdominal defect treatment, and notably, itenabled infection control by reconstruction using muscle.

    Sugimoto, Kenjiro; Kamata, Sei-Ichiro

    2015-11-01

    This paper presents an efficient constant-time bilateral filter that produces a near-optimal performance tradeoff between approximate accuracy and computational complexity without any complicated parameter adjustment, called a compressive bilateral filter (CBLF). The constant-time means that the computational complexity is independent of its filter window size. Although many existing constant-time bilateral filters have been proposed step-by-step to pursue a more efficient performance tradeoff, they have less focused on the optimal tradeoff for their own frameworks. It is important to discuss this question, because it can reveal whether or not a constant-time algorithm still has plenty room for improvements of performance tradeoff. This paper tackles the question from a viewpoint of compressibility and highlights the fact that state-of-the-art algorithms have not yet touched the optimal tradeoff. The CBLF achieves a near-optimal performance tradeoff by two key ideas: 1) an approximate Gaussian range kernel through Fourier analysis and 2) a period length optimization. Experiments demonstrate that the CBLF significantly outperforms state-of-the-art algorithms in terms of approximate accuracy, computational complexity, and usability. PMID:26068315

    2008-01-01

    The influence of fatiguing stimuli applied to the quadriceps femoris on the tremor of the index finger on sixteen healthy subjects has been investigated, by measuring the acceleration and the electromyography activity of the extensor digitorum at two different speeds. No significant changes in the basal condition could be measured at 0.52 rad/s. However, at 1.05 rad/s the tremor amplitude (12.23%, p<0.05) and the electromyography activity (20.19%, p<0.05) increased in the time domain. In the frequential domain, the peak associated to the acceleration increased in 26.30% (p<0.05), while the electromiography activity experienced an increase of 81.34% (p<0.05). The largest change in frequency took place in the range 7-17 Hz. The discussion of the results leads to the conclusion that the supraespinal mechanism is responsible for the measured effect.

    Interlimb reflexes contribute to the central neural coordination between different limbs in both humans and animals.

    ·AIM: To compare surgically induced astigmatism(SIA)following horizontal rectus muscle recession surgery between suspension recession with both the "hang-back" technique and conventional recession technique.·METHODS: Totally, 48 eyes of 24 patients who had undergone horizontal rectus muscle recession surgery were reviewed retrospectively. The patients were divided into two groups. Twelve patients were operated on by the hang-back technique(Group 1), and 12 by the conventional recession technique(Group 2). SIA was calculated on the 1stwk, 1stand in the 3rdmo after surgery using the SIA calculator.·RESULTS: SIA was statistically higher in the Group 1all postoperative follow-up. SIA was the highest in the 1st wk, and decreased gradually in both groups.·CONCLUSION: The suspension recession technique induced much more SIA than the conventional recession technique. This difference also continued in the following visits. Therefore, the refractive power should be checked postoperatively in order to avoid refractive amblyopia.Conventional recession surgery should be the preferred method so as to minimize the postoperative refractive changes in patients with amblyopia.

    Full Text Available Spontaneous rectus sheath hematoma (SRSH is an uncommon medical emergency in the elderly. We present a case of SRSH with an atypical clinical presentation and discuss literature regarding diagnosis and proper management. A 75-year-old female patient was transferred to the emergency department due to acute dyspnoea and confusion. Her medical history revealed a viral infection of the upper respiratory tract, and no coughing or use of anticoagulants. The clinical examination showed tenderness of the left lower abdomen, although palpation was misleading due to patient’s obesity. Laboratory investigations showed light anaemia. Ultrasonography and computed tomography revealed a large rectus sheath hematoma of the left abdominal wall. Despite further deterioration of the patient, conservative management including bed rest, fluid replacement, blood products transfusion, and proper analgesia was successful. No surgical intervention was needed. Prompt diagnosis and management of SRSH plays significant role in the prognosis, especially in elder patients. Independently of size and severity, conservative management remains the first therapeutic choice. Only by failure of supportive management, progressive and large hematoma or uncontrollable hemodynamic patients, interventional management including surgery or less invasive newer techniques is indicated.

    Laparoscopic ventral hernia repair has been shown to offer improved patient recovery, when compared to open repair. It has also been shown to offer a lower complication rate. However, in patients with high body-mass index and large defects, the intraperitoneal on-lay technique of laparoscopic repair is criticized for an increased incidence of failure. In 1990, a study introduced the technique of open-component separation, hence enabling the medialization of the rectus muscle and decreasing the incidence of recurrence associated with primary repair. Open-component separation is associated with increased wound problems due to extensive dissection. Different laparoscopic and endoscopic modifications to the open-component-separation technique have been tried to minimize wound problems. In this article, we present our case series of 4 patients involving the laparoscopic component-separation technique of rectus medialization and, laparoscopic ventral hernia combined. This is one of the first series ever reported to involve both modalities of hernia repair in using an exclusive laparoscopic technique. PMID:19694565

    The subscapular artery arises from the third part of the axillary artery and gives off the circumflex scapular and the thoracodorsal arteries. Although anatomical variations of the axillary artery are very common, the existence of a unilateral accessory thoracodorsal artery has been described in the literature only once. There are no reports of bilateral accessory thoracodorsal artery, in the literature. In the present study, a bilateral accessory thoracodorsal artery, originating on either side of the third part of the axillary artery, is described in a 68-year-old female cadaver. All the other branches of the axillary artery had a typical origin, course, distribution and termination. This extremely rare anatomical variation apart from the anatomical importance also has clinical significance for surgeons in this area. Especially, during the dissection or mobilization of the latissimus dorsi that is partly used for coverage problems in many regions of the body and also in dynamic cardiomyoplasty, any iatrogenic injury of this accessory artery may result in ischemia and functional loss of the graft.

    Insertional tendinopathy of the adductors and rectus abdominis is common in male athletes, especially in soccer players. It may be worsened by physical activity and it usually limits sport performance. The management goal in the acute phase consists of analgesic and anti-inflammatory drugs and physical rehabilitation. In the early stages of rehabilitation, strengthening exercises of adductors and abdominal muscles, such as postural exercises, have been suggested. In the sub-acute phase, muscular strength is targeted by overload training in the gym or aquatherapy; core stability exercises seem to be useful in this phase. Finally, specific sport actions are introduced by increasingly complex exercises along with a preventive program to limit pain recurrences. PMID:23738289

    Full Text Available Bloody tear is a rare and distinct clinic phenomenon. We report a case presenting with the complaint of recurrent episodes of bilateral bloody tearing. A 16-year-old girl presented to our clinic with complaint of bloody tearing in both eyes for 3 months. Bloody tearing was not associated with her menses. A blood-stained discharge from the punctum was not observed during the compression of both nasolacrimal ducts. Nasolacrimal passage was not obstructed. Imaging studies such as dacryocystography and gradient-echo magnetic resonance imaging (MRI of nasolacrimal canal were normal. Intranasal endoscopic evaluation was normal. We collected samples from bloody tears two times and pathological examination was performed. Pathological analysis showed lots of squamous cells and no endometrial cells; dysplastic cells were found. Further evaluations for underlying causes were unremarkable. No abnormalities were found in ophthalmologic, radiologic, and pathologic investigations. This condition is likely a rare abnormality and the least recognized aetiology for the idiopathic phenomenon.

    1985-04-01

    A 38-year-old man with brittle, juvenile onset diabetes mellitus and bilateral severe dry eyes with recurrent corneal ulcers developed atypical band-shaped calcifications of both corneas during a 24-hour period. Serum calcium, phosphate, and carbon dioxide levels all were within normal limits. The patient was mildly uremic but was not in renal failure. When EDTA chelation failed to clear the deposits, partial keratectomies were performed in both eyes and the specimens were examined by light and electron microscopy, including energy dispersive x-ray analysis. Microscopic studies revealed an atypical calcific keratopathy which involved neither Bowman's layer nor the most superficial stromal lamellae. The deposits were confined to deeper lamellae in the anterior stroma and by electron microscopy were composed of extracellular crystalline aggregates. Energy dispersive x-ray analysis of these aggregates confirmed the presence of calcium and phosphate. Corneal dessication appeared to be a major contributing factor in the rapid formation of these deposits.

    1991-01-01

    Full Text Available Duane′s retraction syndrome is a well known congenital musculo-facial anomaly. Various explanations have been given for the aetiology of this syndrome. Inverse Duane′s retraction syndrome is a condition with reverse clinical features. Abduction of the affected eye is possible to some extent and is accompanied by retraction of the eyeball, narrowing of the palpebral fissure and pseudoptosis. There may be some restriction of movement on adduction. The primary lesion is suspected to be in the medial rectus muscle. Frequently the muscle is found to be entrapped following trauma to the medial wall of the orbit. A case of bilateral inverse Duane′s retraction syndrome and convergent squint along with left-sided perceptive deafness is reported. As is usually the case there was no structural abnormality or entrapment of the muscle from trauma.

    1990-12-01

    Full Text Available A 35-year-old female with pyoderma gangrenosum developed paraparesis with a sensory level at L1. Three months later she complained of diplopia and was found to have bilateral internuclear ophthalmoplegia with exotropia and no ocular convergence. The term Webino syndrome has been coined to design this set of neuro-opthalmologic findings. Although it was initially attributed to lesions affecting the medial longitudinal fasciculus and the medial rectus subnuclei of the oculomotor complex in the midbrain the exact location of the lesion is still disputed. In the present case both myelopathy and Webino syndrome were probably due to vascular occlusive disease resulting from central nervous system vasculitis occurring in concomitance to pyoderma gangrenosum.

    Full Text Available Purpose: The purpose of this study is to evaluate the lateral rectus periosteal fixation and partial vertical rectus transpositioning (VRT as treatment modalities to correct exotropic Duane retraction syndrome (Exo-DRS. Materials and Methods: Prospective interventional case study of cases of Exo-DRS with limitation of adduction. A total of 13 patients were subdivided into two groups. Six patients underwent only lateral rectus periosteal fixation (group A and seven patients also underwent partial VRT (group B. Assessment involved prism bar cover test, abduction and adduction range, extent of binocular single visual field and exophthalmometry. These tests were repeated at 1 week, 1 month and 3 months post-operatively and data analyzed. Results: The pre-operative mean values and ranges were 26.2 Δ (22-35 exotropia for group A and −21.3 Δ (14-30 exotropia for group B. The post-operative mean and range was +0.6 Δ esotropia (+20 to −8 for group A and 8 Δ (−2 to −20 exotropia for group B. Mean grade of limitation of abduction changed from −3.8 to −3.6 versus −3.6 to −2.8 and mean grade of limitation of adduction changed from −1.9 to −0.7 versus −1.5 to −0.5 in the groups A and B respectively. Mean binocular single visual field changed from 14.7° to 23.3° in group A and 11.8° to 26.4° in the group B respectively. Conclusion: Lateral rectus periosteal fixation is an effective surgery to correct the exodeviation, anomalous head posture and improving adduction in Exo-DRS and partial VRT in addition is effective in improving abduction and binocular single visual fields.

    Return to physical activity following childbirth can be a difficult process complicated by structural changes during pregnancy. A common problem is the development of a diastasis of the rectus abdominus (DRA), defined as a horizontal separation of the abdominus muscles at the linea alba. Recent data indicate that the greater the distance of separation of the muscle, the worse the functional ability. We describe a 24-year-old active duty U.S. Navy female G1P2 with a diagnosis of DRA. At 2 months postpartum, she was referred to physical therapy because of back pain and inability to meet baseline activities of daily living. After 4 months of physical therapy, she was unable to complete curl ups as required by U.S. Navy physical fitness standards. Abdominoplasty with imbrication of the abdominal wall diastasis was performed followed by additional physical therapy, after which she returned to baseline functioning. The restoration of functional ability postoperatively suggests there is a therapeutic indication for surgical correction of DRA. In high-functioning military patients with DRA who fail to return to baseline level of activity following a trial of physical therapy, surgical intervention should be considered to obtain the optimal functional ability.

    Hayashi, Akiteru; Maruyama, Yu

    2005-02-01

    The single-stage technique for cross-face reanimation of the paralyzed face without nerve graft is an improvement over the two-stage procedure because it results in early reinnervation of the transferred muscle and shortens the period of rehabilitation. On the basis of an anatomic investigation, the short head of the biceps femoris muscle with attached lateral intermuscular septum of the thigh was identified as a new candidate for microneurovascular free muscle transfer. The authors performed one-stage transfer of the short head of the biceps femoris muscle with a long motor nerve for reanimation of established facial paralysis in seven patients. The dominant nutrient vessels of the short head were the profunda perforators (second or third) in six patients and the direct branches from the popliteal vessels in one patient. The recipient vessels were the facial vessels in all cases. The length of the motor nerve of the short head ranged from 10 to 16 cm, and it was sutured directly to several zygomatic and buccal branches of the contralateral facial nerve in six patients. One patient required an interpositional nerve graft of 3 cm to reach the suitable facial nerve branches on the intact side. The period required for initial voluntary movement of the transferred muscles ranged from 4 to 10 months after the procedures. The period of postoperative follow-up ranged from 5 to 42 months. Transfer of the vascularized innervated short head of the biceps femoris muscle is thought to be an alternative for one-stage reconstruction of the paralyzed face because of the reliable vascular anatomy of the muscle and because it allows two teams to operate together without the need to reposition the patient. The nerve to the short head of the biceps femoris enters the side opposite the vascular pedicle of the muscle belly, and this unique relationship between the vascular pedicle and the motor nerve is anatomically suitable for one-stage reconstruction of the paralyzed face.

    Economou Nicolas C

    2006-10-01

    Full Text Available Abstract Background The most common causes of hemotympanum are therapeutic nasal packing, epistaxis, blood disorders and blunt trauma to the head. Hemotympanum is characterized as idiopathic, when it is detected in the presence of chronic otitis media. A rare case of spontaneous bilateral hemotympanum in a patient treated with anticoagulants is presented herein. Case presentation A 72-year-old male presented with acute deterioration of hearing. In the patient's medical history aortic valve replacement 1 year before presentation was reported. Since then he had been administered regularly coumarinic anticoagulants, with INR levels maintained between 3.4 and 4.0. Otoscopy revealed the presence of bilateral hemotympanum. The audiogram showed symmetrical moderately severe mixed hearing loss bilaterally, with the conductive component predominating. Tympanograms were flat bilaterally with absent acoustic reflexes. A computerized tomography scan showed the presence of fluid in the mastoid and middle ear bilaterally. Treatment was conservative and consisted of a 10-day course of antibiotics, anticongestants and temporary interruption of the anticoagulant therapy. After 3 weeks, normal tympanic membranes were found and hearing had returned to previous levels. Conclusion Anticoagulant intake should be included in the differential diagnosis of hemotympanum, because its detection and appropriate treatment may lead to resolution of the disorder.

    2016-01-01

    Background: The aim of this study was to define the indicators predicting improved abdominal wall function after surgical repair of abdominal rectus diastasis (ARD). Preoperative subjective assessment quantified by the validated Ventral Hernia Pain Questionnaire (VHPQ) was related to relative postoperative functional improvement in abdominal muscle strength. Methods: Fifty-seven patients undergoing surgery for ARD completed the VHPQ before surgery. Preoperative pain assessment results were compared with the relative improvement in muscle strength measured with the BioDex system 4. Results: There was a correlation between the relative improvement in muscle strength measured by the BioDex System 4 for flexion at 30 degrees (P = 0.046) and 60 degrees per second (P = 0.004) and the preoperative question, “Do you find it painful to sit for more than 30 minutes?” There was also a correlation between BioDex improvement for flexion at 30 degrees (P = 0.022) and for isometric work load (P = 0.038) and the preoperative question, “Has abdominal pain limited your ability to perform sports activities?” The VHPQ responses also formed a pattern with a fairly good correlation between other BioDex modalities (with the exception of extension at 60 degrees per second) and the response to the question regarding complaints when performing sports. Postoperative visual analog scale ratings of abdominal wall stability correlated to the questions regarding complaints when sitting (P = 0.040) and standing (P = 0.047). No other correlation was seen. Conclusion: VHPQ ratings concerning pain while being seated for more than 30 minutes and pain limiting the ability to perform sports are promising indicators in the identification of patients likely to benefit from surgical correction of their ARD.

    Background:Spontaneous potentials in electromyography (EMG) ofparaspinal muscles are associated with diaphragm denervation and,therefore,poor respiratory function in amyotrophic lateral sclerosis (ALS) is understandable.EMG changes in the rectus abdominis (RA)display an effect similar to those in paraspinal muscles with respect to the function of lower motor neurons in the thoracic spinal cord.The RA denervation was examined to determine its association with ventilation dysfunction in ALS.Methods:We collected the clinical data of 128 patients with sporadic ALS in Department of Neurology of Peking University Third Hospital from 2009 to 2013.EMG,Revised ALS Functional Rating Scale (ALSFRS-R) and forced vital capacity (FVC) were performed in all patients and the differences in the EMG changes in RA between those with and without FVC ≥ 80% were analysed.Results:The mean FVC value was 83.4% ± 17.1% (range:45%-131%) of the predicted value.A total of 79 patients displayed FVC ≥80%,and 49 patients displayed FVC <80%.Compared with the patients displaying a normal FVC (60/79,75.9%),spontaneous activity in RA was significantly different among those patients displaying an FVC <80% (47/49,95.9%).In addition,spontaneous potentials in RA were more frequently detected in patients exhibiting dyspnea (32/33,97.0%) than in patients without dyspnea (75/95,78.9%).Conclusion:Spontaneous potentials in RA are associated with ventilation dysfunction and dyspnea in ALS patients.

    Purpose Overcorrection of hypotropia subsequent to adjustable suture surgery following inferior rectus recession is undesirable, often resulting in persistent diplopia and reoperation. I hypothesized that overcorrection shift after suture adjustment may be unique to thyroid eye disease, and the use of a nonabsorbable suture may reduce the occurrence of overcorrection. Methods A retrospective chart review of adult patients who had undergone eye muscle surgery with an adjustable suture technique was performed. Overcorrection shifts that occurred between the time of suture adjustment and 2 months postoperatively were examined. Descriptive statistics, linear regression, Anderson-Darling tests, generalized Pareto distributions, odds ratios, and Fisher tests were performed for two overcorrection shift thresholds (>2 and >5 prism diopters [PD]). Results Seventy-seven patients were found: 34 had thyroid eye disease and inferior rectus recession, 30 had no thyroid eye disease and inferior rectus recession, and 13 patients had thyroid eye disease and medial rectus recession. Eighteen cases exceeded the 2 PD threshold, and 12 exceeded the 5 PD threshold. Statistical analyses indicated that overcorrection was associated with thyroid eye disease (P=6.7E-06), inferior rectus surgery (P=6.7E-06), and absorbable sutures (>2 PD: OR=3.7, 95% CI=0.4–35.0, P=0.19; and >5 PD: OR=6.0, 95% CI=1.1–33.5, P=0.041). Conclusions After unilateral muscle recession for hypotropia, overcorrection shifts are associated with thyroid eye disease, surgery of the inferior rectus, and use of absorbable sutures. Surgeons performing unilateral inferior rectus recession on adjustable suture in the setting of thyroid eye disease should consider using a nonabsorbable suture to reduce the incidence of postoperative overcorrection.

    Eccentric exercise can result in muscle damage and interleukin-6 (IL-6) secretion. Glycogen availability is a potent stimulator of IL-6 secretion. We examined effects of eccentric exercise in a low-glycogen state on neuromuscular function and plasma IL-6 secretion. Twelve active men (23 ± 4 yr, 179 ± 5 cm, 77 ± 10 kg, means ± SD) completed two downhill treadmill runs (gradient, -12%, 5 × 8 min; speed, 12.1 ± 1.1 km/h) with normal (NG) and reduced muscle glycogen (RG) in randomized order and at least 6 wk apart. Muscle glycogen was reduced using an established cycling protocol until exhaustion and dietary manipulation the evening before the morning run. Physiological responses were measured up to 48 h after the downhill runs. During recovery, force deficits of musculus quadriceps femoris by maximal isometric contractions were similar. Changes in low-frequency fatigue were larger with RG. Voluntary activation and plasma IL-6 levels were similar in recovery between conditions. It is concluded that unaccustomed, damaging eccentric exercise with low muscle glycogen of the m. quadriceps femoris 1) exacerbated low-frequency fatigue but 2) had no additional effect on IL-6 secretion. Neuromuscular impairment after eccentric exercise with low muscle glycogen appears to have a greater peripheral component in early recovery. PMID:27150832

    Full Text Available A multiple-ligament knee injury that includes posterolateral corner (PLC disruption often causes palsy of the common peroneal nerve (CPN, which occurs in 44% of cases with PLC injury and biceps femoris tendon rupture or avulsion of the fibular head. Approximately half of these cases do not show functional recovery. This case report aims to present a criteria-based approach to the operation and postoperative management of CPN palsy that resulted from a multiple-ligament knee injury in a 22-year-old man that occurred during judo. We performed a two-staged surgery. The first stage was to repair the injuries to the PLC and biceps femoris. The second stage involved anterior cruciate ligament reconstruction. The outcomes were excellent, with a stable knee, excellent range of motion, and improvement in the palsy. The patient was able to return to judo competition 27 weeks after the injury. To the best of our knowledge, this is the first case report describing a return to sports following CPN palsy with multiple-ligament knee injury.

    Full Text Available Objetivo: Transposição vertical dos músculos retos horizontais é a técnica de eleição para as anisotropias verticais em que não há disfunção de músculos oblíquos que as justifique. O objetivo foi avaliar o resultado das transposições efetuadas e identificar quais os fatores determinantes do resultado, para estabelecer-se relação que informe a magnitude da transposição que deva ser realizada para determinada magnitude de anisotropia. Métodos: Avaliaram-se retrospectivamente 43 pacientes portadores de anisotropias em A ou V, associado a estrabismos horizontais essenciais, sem disfunção de músculos oblíquos, submetidos à transposição vertical bilateral e simétrica dos músculos retos horizontais Resultados: 81,4% dos pacientes apresentavam esotropia com forma em A. A média das anisotropias situou-se em torno das 19 DP e a maior parte das transposições foi de 4mm, obtendo-se 66,7 a 79,5% de sucesso, isto é, casos com anisotropias residuais em A até 5 DP ou V até 10 DP. A correção da anisotropia correlaciona-se intensamente com a magnitude da anisotropia pré-operatória e com a magnitude da transposição efetuada, sobretudo com aquela, sugerindo assim ser o procedimento auto-ajustável. A equação linear com as 3 variáveis mostrou-se clinicamente incoerente e foi, portanto, abandonada. Conclusões: A transposição vertical e simétrica dos músculos retos horizontais é eficaz para o tratamento das anisotropias verticais sem disfunção de oblíquos, sendo este resultado estável em seguimento prolongado.Purpose: Vertical transpositions of the horizontal rectus muscles is the preferred operation in cases of A and V pattern strabismus in which oblique muscle dysfunction is inadequate to allow oblique surgery.

    2015-12-01

    Full Text Available Tensor fascia suralis muscle is an anomalous muscle located in popliteal fossa. The muscle may arise from any of the hamstring muscles and is inserted into the crural fascia or tendoclacaneus. We found tensor fascia suralis muscle in a male cadaver taking origin from medial side of tendon of biceps femoris muscle. The tendinous origin was then transformed into a well defined fusiform belly in the roof of popliteal fossa. After traversing downwards and medially the muscle again became tendinous to get inserted into deep fascia of leg. Bilateral presentation of the anomalous muscle is not yet documented in literature. The anatomical relation of the muscle explains its great clinical importance. The tendinous origin was anteriorly related to sciatic nerve and the muscle belly to the tibial nerve. Sural nerve and short saphenous vein were in lateral relation to the muscle. Contraction of muscle in the roof of popliteal fossa may lead to sciatic, tibial or sural nerve neuropathy. The muscle can confuse the physician of a soft tissue mass or an aberrant vessel. Hence, the bilateral presence of tensor fascia suralis muscle is documented for further references. Clinical Significance: The precise knowledge of anatomy of popliteal region is mandatory for the surgeons to perform safe and uncomplicated surgery in and around popliteal fossa and also for radiologist for correct radiographic interpretations.

    We aimed to characterize rectus abdominis, internal oblique, and external oblique muscle activity in healthy adults under expiratory resistance using surface electromyography. We randomly assigned 42 healthy adult subjects to 3 groups: 30%, 20%, and 10% maximal expiratory intraoral pressure (PEmax). After measuring 100% PEmax and muscle activity during 100% PEmax, the activity and maximum voluntary contraction of each muscle during the assigned experimental condition were measured. At 100% PEmax, the external oblique (pexpiration. Moreover, 30% PEmax is the minimum intensity required to achieve significant, albeit very slight, muscle activity during expiratory resistance.

    Full Text Available Background: Primary synchronous bilateral breast cancer (PSBBC is a rare clinical entity. The reported incidence ranges between 0.3% and 12%. There are several controversial issues regarding PSBBC pertaining to the diagnostic criteria, nomenclature, and management policies. Materials and Methods: Fourteen cases of PSBBC treated between 2001 to 2010 at our institute were retrospectively analysed in regards to demographic data, management and follow up. Results: PSBBC constituted 0.19% of total breast cancer patients at our institute. Age ranged from 28 to 78 years. PSBBC were detected by clinical examination in eight cases and by mammography in six cases. Twelve patients underwent bilateral modified radical mastectomy, one had unilateral mastectomy on one side and breast conservation on the other side and one patient has bilateral breast conservation. Majority of patients belonged to stage 2 and stage 3. All patients were found to have invasive ductal carcinoma. Five cases were ER/PR positive and 8 patients were triple hormone receptor negative. Eight patients received unilateral and six received bilateral adjuvant radiotherapy. Nine patients received adjuvant chemotherapy. 5 patients received adjuvant hormonal therapy. Median follow up of patients was 15.4 months. Conclusion: PSBBC is a rare event warranting awareness and screening of the contralateral breast in patients with unilateral breast cancer. These patients require individualized treatment planning based on the tumor factors of the index lesion. Further multi institutional prospective studies are needed for adequate understanding of management of PSBBC.

    Electromyography (EMG) is one of the indirect tools in indexing fatigue. Fatigue can be detected when there are changes on amplitude and frequency. However, various outcomes from literature make researchers conclude that EMG is not a reliable tool to measure fatigue. This paper investigates EMG behavior of biceps femoris in median frequency and mean absolute value during five days of Bruce Protocol treadmill test. Before that, surface EMG signals are filtered using band pass filter cut-off at 20-500Hz and are de-noised using db45 1-decimated wavelet transform. Five participants achieved more than 85% of their maximal heart rate during the running activity. The authors also consider other markers of fatigue such as performance, muscle soreness and lethargy as indicators to adaptation and maladaptation conditions. Result shows that turning points of median frequency and mean absolute value are very significant in indexing fatigue and indicators to adaptation of resistive training. PMID:26737713

    To evaluate the involvement of the iliotibial band (ITB), the anterolateral ligament (ALL), and the anterior arm of the biceps femoris in MRI-diagnosed Segond fracture and to evaluate other associated findings of Segond fracture. We retrospectively reviewed the MRI of 13 cases of Segond fracture. The studies included proton density-weighted, T2-weighted, and proton density-weighted with fat saturation images in the three planes. We studied 2 cadaveric specimens with emphasis on the ALL. One cadaveric specimen was dissected while the other was sectioned in the sagittal plane. The mean age of the patients was 36 years (range, 17-52). There were 7 men and 6 women. The mean size of the Segond bone fragment was 8 x 10 x 2 mm. The distance from the tibia varied from 2 to 6 mm. Associated findings included anterior cruciate ligament (ACL) tear (n = 13), medial collateral ligament (MCL) tear (n = 8), meniscocapsular tear of the posterior horn of the medial meniscus (n = 5), and posterolateral corner involvement (n = 4). Bone marrow edema involved the mid-lateral femoral condyle and the posterior tibial plateau on both the medial and the lateral side. Edema at the Segond area was seen, but was limited. Fibular head edema was also seen. The ITB (11 out of 13) and ALL (10 out of 13) inserted on the Segond bone fragment. The anterior arm of the biceps tendon did not insert on the Segond fracture. Associated findings of Segond fracture include ACL tear, MCL tear, medial meniscus tear, and posterolateral corner injury. Both the ITB and the ALL may be involved in the Segond avulsion. The anterior arm of the biceps femoris tendon is not involved. (orig.)

    Full Text Available OBJECTIVE: To evaluate the efficacy and safety of bilateral pallidotomies in five patients with generalized dystonia. BACKGROUND: Generalized dystonias are frequently a therapeutic challenge, with poor responses to pharmacological treatment. GPi (globus pallidus internus pallidotomies for Parkinson's disease ameliorate all kinds of dyskinesias/dystonia, and recent studies reported a marked improvement of refractory dystonias with this procedure. METHODS: Five patients with generalized dystonias refractory to medical treatment were selected; one posttraumatic and four idiopathic. The decision to perform bilateral procedures was based on the predominant axial involvement in these patients. Dystonia severity was assessed with the Burke-Fahn-Marsden Dystonia Scale (BFM. Simultaneous procedures were performed in all but one patient, who had a staged procedure. They were reevaluated with the same scale (BFM by an unblinded rater at 1, 2, 3, 30, 60, 90, 120 and 180 days post-operatively. RESULTS: The four patients with idiopathic dystonia showed a progressive improvement up to three months; the patient with posttraumatic dystonia relapsed at three months. One patient had a marked improvement, being able to discontinue all the medications. A mean decrease in the BFM scores of 52,58% was noted. One patient had a trans-operative motor seizure followed by a transient hemiparesis secondary to rack hemorrhage; other was lethargic up to three days after the procedure. CONCLUSIONS: Our results show that bilateral GPi pallidotomies may be a safe and effective approach to medically refractory generalized dystonias; it can also be speculated that the posttraumatic subgroup may not benefit with this procedure.As distonias generalizadas são freqüentemente um desafio terapêutico, com pobres respostas aos tratamentos farmacológicos.

    Full Text Available Lhermitte-Duclos disease (LDD is a pathologic entity with progrediating, diffuse hypertrophy chiefly of the stratum granulosum of the cerebellum. Typically LDD is a unilateral lesion of the cerebellum or in vermis. Here we report a case of LDD with bilateral lesions of cerebellar hemispheres managed surgically. A 28-year-old woman presented with one-year history of progressive headache, nausea, vomiting, and blurred vision. Neurologic examination revealed a bilateral mild papilledema, mild dysmetria, and dysdiadochokinesia. The cerebellar lesions caused moderate mass effect in posterior fossa with hydrocephalus, and Chiari type I malformation. We performed the suboccipital-retrosigmoid approach, and removed completely the left intracerebellar mass. Symptoms related to elevated intracranial pressure disappeared in a short period postoperatively.

  3. Compensation following bilateral vestibular damage

    Directory of Open Access Journals (Sweden)

    Bill J Yates

    2011-12-01

    Full Text Available Bilateral loss of vestibular inputs affects far fewer patients than unilateral inner ear damage, and thus has been understudied. In both animal subjects and human patients, bilateral vestibular hypofunction (BVH produces a variety of clinical problems, including impaired balance control, inability to maintain stable blood pressure during postural changes, difficulty in visual targeting of images, and disturbances in spatial memory and navigational performance. Experiments in animals have shown that nonlabyrinthine inputs to the vestibular nuclei are rapidly amplified following the onset of BVH, which may explain the recovery of postural stability and orthostatic tolerance that occurs within 10 days. However, the loss of the vestibulo-ocular reflex and degraded spatial cognition appear to be permanent in animals with BVH. Current concepts of the compensatory mechanisms in humans with BVH are largely inferential, as there is a lack of data from patients early in the disease process. Translation of animal studies of compensation for BVH into therapeutic strategies and subsequent application in the clinic is the most likely route to improve treatment. In addition to physical therapy, two types of prosthetic devices have been proposed to treat individuals with bilateral loss of vestibular inputs: those that provide tactile stimulation to indicate body position in space, and those that deliver electrical stimuli to branches of the vestibular nerve in accordance with head movements. The relative efficacy of these two treatment paradigms, and whether they can be combined to facilitate recovery, is yet to be ascertained.

    Electroconvulsive therapy (ECT) is the most effective treatment for patients suffering from severe or treatment-resistant major depressive disorder (MDD). Unfortunately its underlying neurobiological mechanisms are still unclear. One line of evidence indicates that the seizures produced by ECT induce or stimulate neuroplasticity effects. Although these seizures also affect the cortex, the effect of ECT on cortical thickness is not investigated until now. We acquired structural magnetic resonance imaging data in 19 treatment-resistant MDD patients before and after a bilateral ECT course, and 16 healthy controls at 2 time points, and compared changes in cortical thickness between the groups. Our results reveal that ECT induces significant, bilateral increases in cortical thickness, including the temporal pole, inferior and middle temporal cortex and the insula. The pattern of increased cortical thickness was predominant in regions that are associated with seizure onset in ECT. Post hoc analyses showed that the increase in thickness of the insular cortex was larger in responders than in non-responders, which may point to a specific relationship of this region with treatment effects of ECT.

    2009-01-01

    Full Text Available Bilateral cleft lip nose deformity is a multi-factorial and complex deformity which tends to aggravate with growth of the child, if not attended surgically. The goals of primary bilateral cleft lip nose surgery are, closure of the nasal floor and sill, lengthening of the columella, repositioning of the alar base, achieving nasal tip projection, repositioning of the lower lateral cartilages, and reorienting the nares from horizontal to oblique position. The multiplicity of procedures in the literature for correction of this deformity alludes to the fact that no single procedure is entirely effective. The timing for surgical intervention and its extent varies considerably. Early surgery on cartilage may adversely affect growth and development; at the same time, allowing the cartilage to grow in an abnormal position and contributing to aggravation of deformity. Some surgeons advocate correction of deformity at an early age. However, others like the cartilages to grow and mature before going in for surgery. With peer pressure also becoming an important consideration during the teens, the current trend is towards early intervention. There is no unanimity in the extent of nasal dissection to be done at the time of primary lip repair. While many perform limited nasal dissection for the fear of growth retardation, others opt for full cartilage correction at the time of primary surgery itself. The value of naso-alveolar moulding (NAM too is not universally accepted and has now more opponents than proponents. Also most centres in the developing world have neither the personnel nor the facilities for the same. The secondary cleft nasal deformity is variable and is affected by the extent of the original abnormality, any prior surgeries performed and alteration due to nasal growth. This article reviews the currently popular methods for correction of nasal deformity associated with bilateral cleft lip, it′s management both at the time of cleft lip repair

These fractures are more common in children than in adults, and mutual Monteggia fracture is a rare complication. This study presents a treatment course of a patient with bilateral Monteggia fracture. Case report. A 55- year-old patient was injured by falling in the yard. Radiography showed bilateral Monteggia fracture type II (by the Badon classification. Operative treatment of fracture was done by a compression plate on the right side and by the zuggurtung technique on the left one. Closed repositioning of the radial head was done on both sides. The patient was wearing a plaster splint for the upper arm for 21 days. After removing the fixation, the function of the elbow was determined by the Broberg Morrey score (BM which was on the right side 45.5 and on the left side 47.5. After the proper physical therapy, four months after the surgery, BM score was 100 on the right side, and 93 on the left one. Conclusion. Surgical treatment and early rehabilitation is the key for the return of good function of both elbows.

    A case report of a 44 year-old white man admitted to the surgical unit for a bilateral simultaneous pneumothorax is presented. The pneumothorax occurred on day one after a surgical operation for discal hernia; in the past the patient already presented a right spontaneous pneumothorax at 32 years of age and a left pneumothorax at 37 years of age, both treated with a pleural drainage. A thoracic drain was bilaterally positioned with a good result only in the right side. The persistence of the left pneumothorax induced the authors to perform a postero-lateral thoracotomy bullae excision and pleurectomy with a good postoperative course. After a few months a new right pneumothorax occurred and the patient was treated with a right postero-lateral thoracotomy, bullae resection and pleurectomy. On the basis of the case reported, the authors consider the different opportunities in the treatment of spontaneous pneumothorax in relation to the present knowledges and technologies. Surgical procedure is to be preferred in case of persistence of pneumothorax despite a pleural drain and in case of pneumothorax in high risk subjects. Even if thoracoscopy seems to give better results regarding postoperative pain, it is not always possible with such a method to perform a careful pleurectomy neither to obtain it in all cases (above all in secondary pneumothorax). Every case must then be carefully studied to choose the best treatment at present available. PMID:11353349

  10. Danish Exports and Danish Bilateral Aid

    DEFF Research Database (Denmark)

    Hansen, Henrik; Rand, John

    Danish bilateral development assistance is aimed at reducing poverty in the partner countries. Even so, bilateral assistance may have secondary, or knock-on, effects, which are beneficial for Denmark. An important secondary effect is the prospect of increased export from Denmark to the partner...... countries. This Evaluation Study presents an econometric analysis of Danish exports to 144 countries over the period from 1981 to 2010. The analysis is based on the gravity model of bilateral trade; a structural model developed over decades and now the central model in analyses of bilateral trade flows...... and trade policies. The main result of the study is that Danish bilateral aid has a positive and statistically significant impact on Danish exports to the recipient countries. Bilateral development assistance may affect exports through several channels. Three of the main channels are direct aid tying...

    Objective: To investigate the clinical effect of the nervus cutaneus femoris posterior pedicle flap on repairing large soft tissue defects at the heel or inferior segment of the shank.Methods: Totally 14 cases were followed up for 8-22 months (mean 15.5 months) to observe the clinical effects of nervus cutaneus femoris posterior pedicle flap on repairing large soft tissue defects of the heel or inferior segment of the shank. Among them, there were 3 patients afflicted with infection and cutaneous defects in the middle and inferior segment of the shank after internal fixation of open fracture, 4 patients with soft tissue defects of the ankle and uncovered tendo calcaneus, and 7 patients with soft tissue defects of the heel and exposed calcaneus.Results: The flaps survived well in 13 cases and partial necrosis occurred in 1 case that was thereafter cured with changing dressing. Various extents of pain and stiffness of the knee joints were present in all cases and disappeared through 1-8 weeks' (mean 3.2 weeks) functional exercises. The last follow-up showed that all the flaps kept good texture and satisfactory appearance.Conclusions: The nervus cutaneus femoris posterior pedicle flap, having the advantages of simple surgical procedures, anastomosing the nerves and restoring the sensation of recipient site, can be used for recovering large soft tissue defects of the shank and ankle.

    The back squat and barbell hip thrust are both popular exercises used to target the lower body musculature; however, these exercises have yet to be compared. Therefore, the purpose of this study was to compare the surface electromyographic (EMG) activity of the upper and lower gluteus maximus, biceps femoris, and vastus lateralis between the back squat and barbell hip thrust. Thirteen trained women (n = 13; age = 28.9 years; height = 164 cm; mass = 58.2 kg) performed estimated 10-repetition maximums (RM) in the back squat and barbell hip thrust. The barbell hip thrust elicited significantly greater mean (69.5% vs 29.4%) and peak (172% vs 84.9%) upper gluteus maximus, mean (86.8% vs 45.4%) and peak (216% vs 130%) lower gluteus maximus, and mean (40.8% vs 14.9%) and peak (86.9% vs 37.5%) biceps femoris EMG activity than the back squat. There were no significant differences in mean (99.5% vs 110%) or peak (216% vs 244%) vastus lateralis EMG activity. The barbell hip thrust activates the gluteus maximus and biceps femoris to a greater degree than the back squat when using estimated 10RM loads. Longitudinal training studies are needed to determine if this enhanced activation correlates with increased strength, hypertrophy, and performance.

    Full Text Available OBJECTIVE: To analyze strength and integrated electromyography (IEMG data in order to determine the neuromuscular efficiency (NME of the vastus lateralis (VL and biceps femoris (BF muscles in patients with anterior cruciate ligament (ACL injuries, during the preoperative and postoperative periods; and to compare the injured limb at these two times, using the non-operated limb as a control.METHODS: EMG data and BF and VL strength data were collected during three maximum isometric contractions in knee flexion and extension movements. The assessment protocol was applied before the operation and two months after the operation, and the NME of the BF and VL muscles was obtained.RESULTS: There was no difference in the NME of the VL muscle from before to after the operation. On the other hand, the NME of the BF in the non-operated limb was found to have increased, two months after the surgery.CONCLUSIONS: The NME provides a good estimate of muscle function because it is directly related to muscle strength and capacity for activation. However, the results indicated that two months after the ACL reconstruction procedure, at the time when loading in the open kinetic chain within rehabilitation protocols is usually started, the neuromuscular efficiency of the VL and BF had still not been reestablished.

    Full Text Available Introduction: Quadriceps is one of the strongest muscle of the body that is required for knee mobility. Quadriceps plays a crucial role in many daily activities such as walking, twisting, running, jumping, and controlling the movement of knee. Since it’s a two joint muscle, they tend to become very to tight leading to imbalance, which can give rise to a number of postural problems and common musculoskeletal disorder causing pain in the knee joint. It could be acute, subacute and chronic in its clinical presentation. Hence strengthening of quadriceps femoris is necessary. Materials and Methods: a total of 90 participants within age of 21 to 29 years and BMI 19.9 to 24.9 having no neurological, cardiopulmonary and musculoskeletal disease were selected. Results: of the total 90 subjects, the mean age of the participants in group A 21.67±0.88 the mean age of participants in group B was 22.23±1.33 and the mean age of participants in the group C was 22.03±1.27. The result showed high significance in the group B. Conclusion: the study showed increase in the quadriceps muscle strength in group B.

    Since musculoskeletal impairment increases with age, it is important to determine if exercise changes age-related muscle weakness. This study compared the training effects of electrical stimulation and voluntary isometric contraction, the traditional exercise, on the quadriceps femoris in males 65 years and older. Eighteen informed, nondisabled males, 72 +/- 4 years of age, participated in 12 training sessions over 4 weeks. Maximal voluntary isometric contraction (MVIC) torque was measured with a Cybex II dynamometer prior to and following training. An interclass correlation coefficient (3,1) of 0.982 demonstrated repeated reliable torque measurement. The electrical stimulation group trained at an average of 36% of pretest MVIC; the traditional exercise group trained at an average of 42% MVIC. Average (F = 14.06, p = 0.004) and peak (F = 14.32, p = 0.004) torque values were increased with both modes of training. Both methods of training using a low training load were effective in increasing torque in this older male sample. Electrical stimulation has the same potential as traditional exercise to provide improved strength for aged males. Future research should examine electrical stimulation in older persons with compromised ability to exercise using traditional methods. PMID:8081406

    The purpose of this study was to evaluate motor unit recruitment in the quadriceps femoris (QF) after anterior cruciate ligament (ACL) rupture and repair. Subjects included 24 patients at ≥ 18 months after ACL reconstruction and 22 control subjects with no history of knee injury. A series of cross-sectional magnetic resonance images were obtained to compare the QF of patients' injured side with that of their uninjured sides and that of uninjured control subjects. Muscle torque per muscle volume was calculated as isokinetic peak torque divided by QF muscle volume (cm(3)). The mean muscle torque per unit volume of the injured side of patients was not significantly different from that of the uninjured side or control subjects (one-way ANOVA) Results of the present study were contrary to the results of a previous study that evaluated patients at ≤ 12 months after ACL reconstruction. The present study found that high-threshold motor unit recruitment was restored at ≥ 18 months after ACL reconstruction. Thus, clinicians must develop techniques that increase the recruitment of high-threshold motor units in the QF from the period immediately after the injury until approximately 18 months after ACL reconstruction.

    Chronic occlusions of the inferior vena cava (IVC) and iliofemoral veins are long-term sequelae of deep venous thrombosis (DVT) that can lead to postthrombotic syndrome (PTS). Patients may present with a wide spectrum of signs and symptoms, ranging from mild discomfort and swelling to severe venous hypertension and ulcerations. We report a 68-year-old man who had a history of left lower extremity DVT after a laminectomy and who developed PTS with nonhealing ulcers. The patient underwent a cross-pubic femorofemoral venous bypass that failed to improve his clinical status. After unsuccessful endovascular attempts for recanalization of the iliofemoral segment, a profunda femoris to IVC bypass was performed. The symptoms recurred 2 years later. Venography revealed restenosis at the caval anastomosis that did not resolve by endovascular means. A surgical revision was performed, and given the quality of the IVC, a jump bypass was created to the left renal vein. The swelling improved and the ulcers healed completely. Twenty-eight months after the complex reconstructions, he remains ulcer-free with mild edema controlled with stockings. Venous reconstructions remain a viable option for patients with symptomatic and recalcitrant nonmalignant obstruction of the large veins.

    We report a case of bilateral complete failure of adduction following bilateral translid antralethmoidal orbital decompression. We believe the probable mechanism is neuropraxia (temporary dysfunction) of the third cranial nerves' supply to the medial recti, owing to these nerves' occupying an anatomically abnormal position. Partial recovery of adduction occurred over the ensuing six months.

    Full Text Available Bilateral ectopic pregnancy is a rare twin gestation with only a few cases reported in the literature. We report a 30 year old woman without any high risk factor for ectopic pregnancy, who had concurrent bilateral ectopic pregnancy. A 30 year old female presented to the Gynecology emergency department complaining of vaginal bleeding and abdominal pain. The presumptive diagnosis of ruptured left sided ectopic pregnancy was made on basis of clinical findings and ultrasound finings. An emergency laparotomy was done revealed a hemoperitoneum of 1.5 liters, a ruptured left tubal pregnancy with active bleeding and right tubal un-ruptured ectopic was found. A bilateral salpingectomy was performed. Histopathology confirmed presence of chorionic villi in both tubes. In theory, laparoscopic salpingostomy is the best surgical approach in bilateral tubal pregnancy. However, bilateral salpingectomy may be necessary when both tubes are extensively damaged or are actively bleeding. Successful pregnancies have been reported after conservative surgical treatment of bilateral ectopic, but the risk of recurrence is high. Our decision for an emergency laparotomy followed by bilateral salpingectomy was based on the fact that the patient presented with acute abdomen and was haemodynamically unstable and there was extensive bilateral tubal damage. As the incidence of ectopic pregnancies is increasing concurrently with the incidences of pelvic inflammatory disease and use of assisted fertility techniques; it may be that these and ldquo;rare ectopics and rdquo; will become less uncommon.

    Study Design Cross-sectional repeated measures. Background Rehabilitation of diastasis rectus abdominis (DRA) generally aims to reduce the inter-rectus distance (IRD). We tested the hypothesis that activation of the transversus abdominis (TrA) before a curl-up would reduce IRD narrowing, with less linea alba (LA) distortion/deformation, which may allow better force transfer between sides of the abdominal wall. Objectives This study investigated behavior of the LA and IRD during curl-ups performed naturally and with preactivation of the TrA. Methods Curl-ups were performed by 26 women with DRA and 17 healthy control participants using a natural strategy (automatic curl-up) and with TrA preactivation (TrA curl-up). Ultrasound images were recorded at 2 points above the umbilicus (U point and UX point). Ultrasound measures of IRD and a novel measure of LA distortion (distortion index: average deviation of the LA from the shortest path between the recti) were compared between 3 tasks (rest, automatic curl-up, TrA curl-up), between groups, and between measurement points (analysis of variance). Results Automatic curl-up by women with DRA narrowed the IRD from resting values (mean U-point between-task difference, -1.19 cm; 95% confidence interval [CI]: -1.45, -0.93; PUX-point between-task difference, -0.51 cm; 95% CI: -0.69, -0.34; PUX-point between-task difference, 0.025; 95% CI: 0.004, 0.045; P = .02). Although TrA curl-up induced no narrowing or less IRD narrowing than automatic curl-up (mean U-point difference between TrA curl-up versus rest, -0.56 cm; 95% CI: -0.82, -0.31; PUX-point between-task difference, 0.02 cm; 95% CI: -0.22, 0.19; P = .86), LA distortion was less (mean U-point between-task difference, -0.025; 95% CI: -0.037, -0.012; PUX-point between-task difference, -0.021; 95% CI: -0.038, -0.005; P = .01). Inter-rectus distance and the distortion index did not change from rest or differ between tasks for controls (P≥.55). Conclusion Narrowing of the IRD

    Full Text Available We report the case of a 25-year-old male patient who presented with bilateral panophthalmitis as the initial ocular manifestation of dengue fever. The diagnosis was a little confusing as he initially presented with features suggestive of retrobulbar hemorrhage secondary to his very low platelet count, which is a common feature of dengue fever. Ophthalmic complications are usually seen in young adults who often present at the nadir of thrombocytopenia. Ocular findings may include anterior uveitis, vitritis, retinal hemorrhages, retinal vascular sheathing, yellow subretinal dots, retinal pigment epithelium (RPE mottling, foveolitis that is clinically seen as a round subretinal yellowish lesion at the fovea, retinochoroiditis, choroidal effusion, optic disc swelling, optic neuritis, neuroretinitis, and oculomotor nerve palsy. [1] There is only one reported case of unilateral endogenous panophthalmitis due to dengue fever. Hence, clinicians and ophthalmologists have to be aware of this vision-threatening complication of dengue for early recognition and prompt treatment to save the vision of these young patients and prevent morbidity.

    Simultaneous bilateral inferior petrosal sinus sampling (BIPSS) plays a crucial role in the diagnostic work-up of Cushing’s syndrome. It is the most accurate procedure in the differential diagnosis of hypercortisolism of pituitary or ectopic origin, as compared with clinical, biochemical and imaging analyses, with a sensitivity and specificity of 88–100% and 67–100%, respectively. In the setting of hypercortisolemia, ACTH levels obtained from venous drainage of the pituitary are expected to be higher than the levels of peripheral blood, thus suggesting pituitary ACTH excess as the cause of hypercortisolism. Direct stimulation of the pituitary corticotroph with corticotrophin-releasing hormone enhances the sensitivity of the procedure. The procedure must be undertaken in the presence of hypercortisolemia, which suppresses both the basal and stimulated secretory activity of normal corticotrophic cells: ACTH measured in the sinus is, therefore, the result of the secretory activity of the tumor tissue. The poor accuracy in lateralization of BIPSS (positive predictive value of 50–70%) makes interpetrosal ACTH gradient alone not sufficient for the localization of the tumor. An accurate exploration of the gland is recommended if a tumor is not found in the predicted area. Despite the fact that BIPSS is an invasive procedure, the occurrence of adverse events is extremely rare, particularly if it is performed by experienced operators in referral centres. PMID:27352844

    A nineteen years old woman with ambiguous external genitalia was studied. This condition had been previously identified as a newborn, but her parents refused medical attention and it was reared as a girl. At 12-years, she began spontaneous mammary development, appearing pubic and axillary hair, and clitoral enlargement. The menarche occurred at 15-years and it was followed by irregular periods. Physical examination, showed absence of hirsutism and acne, normal mammary development equivalent to grade V of Tanner. The external genitalia showed fused labio-scrotal folds with an small introitus. The urethral meatus was absent and was later located inside the introitus. There was a big phallus similar to an adult penis with a normal glans, flexed by a chordee. Hormonal determinations discarded congenital adrenal hyperplasia. The karyotype was 46,XX and testosterone levels were in adult male range. Pelvic ultrasonography disclosed a normal uterus and both gonads in confirmed by laparoscopy identifying bilateral ovotestis. Testicular tissue was removed and plastic reconstruction of female genitals was done. PMID:9528217

The procedure must be undertaken in the presence of hypercortisolemia, which suppresses both the basal and stimulated secretory activity of normal corticotrophic cells: ACTH measured in the sinus is, therefore, the result of the secretory activity of the tumor tissue. The poor accuracy in lateralization of BIPSS (positive predictive value of 50-70%) makes interpetrosal ACTH gradient alone not sufficient for the localization of the tumor. An accurate exploration of the gland is recommended if a tumor is not found in the predicted area. Despite the fact that BIPSS is an invasive procedure, the occurrence of adverse events is extremely rare, particularly if it is performed by experienced operators in referral centres. PMID:27352844

    Full Text Available Simultaneous bilateral inferior petrosal sinus sampling (BIPSS plays a crucial role in the diagnostic work-up of Cushing’s syndrome. It is the most accurate procedure in the differential diagnosis of hypercortisolism of pituitary or ectopic origin, as compared with clinical, biochemical and imaging analyses, with a sensitivity and specificity of 88–100% and 67–100%, respectively. In the setting of hypercortisolemia, ACTH levels obtained from venous drainage of the pituitary are expected to be higher than the levels of peripheral blood, thus suggesting pituitary ACTH excess as the cause of hypercortisolism.

    Full Text Available The EU is a world economic power and a major trading partner for most countries. All the time, this region has been interested and has acted towards a free and fair trade. The decrease and even the elimination of tariff and non-tariff barriers in the world trade are among the main objectives of the EU strategy for international trade. At the moment, the elusive outcome of the WTO Doha Round has led to the proliferation of bilateral trade agreements worldwide. Although the EU remains committed to further development of the multilateral trading system, however, the EU still has appealed also to the development of bilateral trade relations. The aim of this paper is to illustrate the current bilateral dimension of the common commercial policy of the EU. In conclusion, to describe this bilateral approach of the EU we are using one word, namely “diversity”.

    Full Text Available The bilateral filter plays a key role in image processing applications due to its intuitive parameterization and its high quality filter result, smoothing homogeneous regions while preserving the edges of the objects. Considering the image as a topological relief, seeing pixel intensities as peaks and valleys, we introduce a way to control the tonal weighting coefficients, the flowing bilateral filter, reducing "halo" artifacts typically produced by the regular bilateral filter around a large peak surrounded by two valleys of lower values. In this paper we propose to investigate exact and approximated versions of CPU and parallel GPU (Graphical Processing Unit based implementations of the regular and flowing bilateral filter using the NVidia CUDA API. Fast implementations of these filters are important for the processing of large 3D volumes up to several GB acquired by x-ray or electron tomography.

    Full Text Available Bilateral anophthalmia is a rare entity and association with septo-optic dysplasia is an even rare condition. The condition is characterized by absent eyeballs in the presence of eyelids, conjunctiva or lacrimal apparatus. Though anophthalmia can be diagnosed clinically, imaging plays a crucial role in delineating the associated anomalies. In addition, often clinical anophthalmia may prove to be severe microphthalmia on imaging. We describe the imaging findings in an infant with bilateral anophthalmia and septo-optic dysplasia.

    Full Text Available Presented modern literature data on the features of the pathogenesis, course, clinical and morphological expression and tumor characteristics, parameters and nodal metastasis of hematogenous bilateral breast cancer. Highlight the results of domestic and foreign studies in recent years to determine the prognostic factors and recurrence of synchronous and metachronous bilateral breast cancer. It was revealed that the frequency of bilateral breast tumor lesions varies widely, ranging from 0.1 to 20%, with metachronous tumors recorded significantly higher (69.6% than the synchronous (22.7%. The probability of occurrence of metachronous breast cancer is higher in women with a family history, as well as if they have a gene mutation BRCA-1. Found that the most common histological type of breast tumor with bilateral lesions is invasive ductal. However, the incidence of invasive lobular cancer and non-invasive lobular cancer is slightly higher among synchronous bilateral cancer compared with unilateral disease. Studies have shown that in a double-sided synchronous breast cancer tumor, as a rule, has a lower degree of differentiation, and the higher the expression level of estrogen receptors and progesterone receptors. Relevance of the issue because the identification of patterns in the study of lymphatic and hematogenous features bilateral metastasis of mammary tumors provides a basis for speculation about the differences in the progression of neoplastic disease in these groups and is a cause for further detailed research in this area to identify and evaluate the prognosis and also the choice of tactics of such patients.

    Full Text Available We report the clinical findings of a patient with severe bilateral keratectasia 34 years after a penetrating keratoplasty (PK in both eyes. An otherwise healthy 67-year-old man complained of deterioration of the eyesight in both eyes over the last 6 months. The patient was diagnosed with bilateral keratoconus at the age of 32 years, and he underwent a bilateral PK. At presentation, visual acuity was 20/200 in the right eye and light perception in the left eye. A Pentacam pachymetric map revealed a central pachymetry of 720 µm in the right eye and of 710 µm in the left eye, as well as an average paracentral pachymetry of 436 and 270 µm in the 9-mm zone in the right and the left eye, respectively. Corneal topography revealed bilateral irregular and asymmetric bowing with generalized steepening and high corneal power. We describe a case of bilateral keratectasia 34 years after PK in a patient who was originally diagnosed with bilateral keratoconus.

    Ninety-nine Charolais heifers were used to study the variability of meat quality traits in relation to the physicochemical characteristics of M. rectus abdominis. The heifers of the same trade class were slaughtered at 33months of age (±4months) and 381kg carcass weight (±31kg). Muscle and bone development scores were evaluated before slaughter. Carcass weight, slaughter age and life average daily gain were recorded. Shear force measurements and meat quality traits were evaluated after 14days of aging. Some physicochemical characteristics were measured 24h post-slaughter. Tenderness was correlated with slaughter age (r=-0.31), bone development (r=-0.22) and life average daily gain (r=+0.37). Tenderness was significantly related to total collagen content (r=-0.24), lipid content (r=+0.27) and I myosin heavy chain proportion (r=+0.24). Juiciness was positively correlated with lipid content (r=+0.31) and I myosin heavy chain proportion (r=+0.20). Flavor intensity was correlated with lipid content (r=+0.26) and mean fiber area (r=+0.24). Shear force was correlated with total collagen, lipid and 27K proteasome sub-unit contents. Taking animal characteristics and muscle properties together in a multiple regression analysis increased the explained tenderness variability to 33%. The independent variables listed in order of importance were life average daily gain, total collagen content, bone development, lipid content, I myosin heavy chain isoform proportion, shear force of broiled meat and slaughter age.

    Background Continent cutaneous diversion (CCD) has been widely used in almost any lower urinary reconstruction. We have been continually trying to modify this procedure because of the high complications rate, especially as they relate to the efferent tube. In this study, we reported a modified procedure with a tapered ileum wrapped by the rectus abdominalis flap (RAMF) and assessed the feasibility of this new technique to achieve urinary continence. Methods A procedure in which two ileal segments were tapered and connected to a U-shaped reservoir was performed in ten dogs. A RAMF with its blood supply was wrapped around one of the tapered ileum, in control groups, the tapered ileum was brought to the abdominal skin. Urodynamic studies were conducted In the 1st, 3rd and 6th months post-operatively. The data of maximum inner pressure (MIP) and functional pressure length (FPL) in every group at each phase were recorded. Retrograde radiograms of the efferent limbs were performed before sacrifice.Results MIP in the study group was significantly higher than that in the control group at each phase (P<0.05). However, no significant differences in MIP or FPL were found in the study group between an empty and full reservoir. In the control group, MIP increased (P<0.05) and FPL decreased significantly (P<0.05) compared with an empty and full reservoir. Retrograde radiograms confirmed that efferent limbs were positioned straigh beneath the abdominal wall. Histological examination of the study group demonstrated a layer of striated muscle around the outside surface of the ileum.Conclusion The continent mechanism of tapered ileum can be enhanced by extra support from wrapped RAMF.

    Rectus sheath hematomas are a frequent but sometimes misdiagnosed disease in patients under anticoagulative drugs, hemodialysis, or simply in the elderly. The most frequent localization is in the lower part of the abdomen: the explanation lies in the anatomy of the abdominal wall, especially in the arcuate line of the rectus sheath. Aim of this work is to explain the reason of the almost constant location correlating the anatomy with the CT features. The rectus abdominis muscle lies between the aponeuroses of the transverse and oblique muscles which form the so called rectus sheath. This arrangement is found from the costal arch to a level approximately between the umbilicus and the pubic symphisis, where the rear layer of the rectus sheath ends with a curved edge, called the arcuate or semicircular line of Douglas. Beneath this line the aponeuroses of the three muscles pass in front of the rectus which is separated from the peritoneum only by the fascia trasversalis, a thin connective layer between the rectus and the preperitoneal fat. In this lower aspect of the muscle the perforating branches of the inferior epigastric artery running in the preperitoneal fat may rupture causing a large hematoma widely spreading in this loose space. 11 cases of rectus sheath hematoma diagnosed over 5 years were reviewed. They were referred to US because of a rapidly growing palpable mass o painful swelling of the abdominal wall with acute anemia. Sonography was performed in 11 patients and CT in 7. 10 hematomas were located in the lower third of the rectus muscle below the arcuate line in the pelvis, 1 was in the upper third of the muscle: the vast majority of pelvic hematomas is easily accounted for by the peculiar anatomy of the region. The diagnosis of hematoma of the rectus abdominis, sometimes misleading, should be included as a differential in all the patients who present with acute abdominal pain and blood loss. The anatomy of abdominal wall correlates well with CT

    Full Text Available PURPOSE: Preoperative imaging evaluation may be useful for determining the position of recti abdominis muscles before their correction. The purpose of this study is to evaluate the accuracy of ultrasonography to measure the width of rectus abdominis muscle diastasis. METHODS: Rectus diastasis was measured by ultrasonography preoperatively in 20 females. Rectus diastasis was measured in seven levels along the anterior rectus sheath by ultrasound after sustained deep inspiration and after expiration. Rectus diastasis, at the same levels, was also measured after its exposition during abdominoplasty by two independent observers, using a surgical compass. These values were compared using Wilcoxon's statistical text, for non independent values. RESULTS: There was no significant difference between the values obtained by ultrasound and those measured during surgery in the supra-umbilical levels and at the level of the umbilicus. However, below the umbilicus these values differed significantly, showing smaller values in the imaging evaluation. CONCLUSION: Ultrasonography is an accurate method to measure rectus diastasis above the umbilicus and at the umbilical level.OBJETIVO: Estudos radiológicos pré-operatórios podem ser úteis para determinar a posição dos músculos retos do abdome antes de sua correção. O objetivo deste estudo é avaliar a acurácia da ultra-sonografia para medir a largura da diástase dos músculos retos do abdome. MÉTODOS: A diástase dos músculos retos foi medida pela ultra-sonografia, no pré-operatório em 20 mulheres. A diástase dos retos foi medida em sete níveis da bainha anterior dos retos foram examinados com ultra-som após inspiração profunda sustentada e após expiração. A diástase dos retos, nos mesmos níveis, foi também medida após sua exposição durante a abdominoplastia, por dois observadores independentes, usando compasso cirúrgico.

    In Brazil electricity is traded through three segments: the spot market that balances offer and demand, with prices calculated by a cost-based computational model; the regulated market , where prices are settled in public auctions, and the free market for bilateral contracts. As spot and regulated market prices are public information, a seller is able to calculate his opportunity price to trade a bilateral contract in the free market by using the non-arbitrage principle. Thus, the seller searches the price of a bilateral contract in the free market that balances his/her revenues with the value expected in case it were negotiated in the regulated and the spot market. Besides the expected revenue, the seller may also consider the CVaR to measure the risk of her/his bilateral contract in the free market. So this paper develops a binomial lattice approach to price bilateral contracts in the free market, considering the seller's opportunity of negotiations in both regulated and spot markets, and measuring the contract risk directly.

  17. Chronic Bilateral Tibial Stress Fractures with Valgus Treated with Bilateral Intramedullary Nailing: A Case Report

    Directory of Open Access Journals (Sweden)

    Steven K Dailey

    2014-01-01

    Full Text Available Introduction: Stress fractures are overuse injuries most commonly seen in athletes, military recruits, and individuals with endocrine abnormalities. It has been demonstrated that chronic cases of anterior tibial stress fractures refractory to conservative management respond well to intramedullary nailing. To our knowledge, only one report has been published concerning patients with bilateral tibial stress fractures treated with bilateral intramedullary nailing. All patients in the series were high-level athletes. We present the case of a non-athletic patient with chronic bilateral tibial stress fractures and associated deformity successfully treated with bilateral intramedullary nails. Case Report: A 23-year-old Caucasian female full-time student presented with chronic bilateral shin pain for approximately five years. She had failed an extensive regimen of conservative management. She was diagnosed with chronic bilateral tibial stress fractures based on history, physical examination, and radiologic findings. She subsequently underwent sequential intramedullary nailing of her tibiae. Both tibiae were in valgus alignment; however, this did not preclude nail placement. The nails deformed upon insertion into the sclerotic canals to conform to the deformation. Post operatively the tibiae united and patient was relieved of her symptoms. Conclusion: Bilateral intramedullary nailing of chronic bilateral tibial stress fractures should be considered as a treatment option for all patients, not just high-level athletes, who fail a trial of conservative management. Additionally, mild to moderate tibial malalignment does not necessarily preclude tibial nailing as the smaller nails placed in sclerotic canals will likely deform on insertion and conform to the canal.

    Currently, no consistent evidence-based guidelines for the management of synchronous bilateral breast cancer (SBBC) exist and it is uncertain how presenting with SBBC affects patients' prognosis. We conducted a review of studies analyzing the association between SBBC and prognosis. The studies...... that reported adjusted effect measures were included in meta-analyses of effect of bilaterality on breast cancer mortality. From 57 initially identified records 17 studies from 11 different countries including 8,050 SBBC patients were included. The quality of the studies varied but was generally low with small...... sample sizes, and lack of consistent, detailed histo-pathological information. When doing meta-analysis on the subgroup of studies that provided adjusted effect estimates on breast cancer mortality (nine studies including 3,631 SBBC cases), we found that bilaterality in itself had a negative impact...

    Pneumolabyrinth describes a condition with entrapped air in the labyrinth and usually occurs in temporal bone fractures that involve the otic capsule. While sporadic cases of bilateral pneumolabyrinth have been reported, cases lacking head trauma are very rare. We report the case of a 43-year-old man who had sudden hearing loss bilaterally after blowing his nose at an interval of 1 year. Although conservative management for the right ear and exploratory tympanotomy with sealing of the possible site of perilymphatic leakage in the left ear were performed, hearing outcome was poor in both ears. To our knowledge, this is the first case of bilateral pneumolabyrinth occurring as a result of nose blowing. PMID:26771019

    Full Text Available A 39-year-old male was admitted to our clinic with symptoms of headache, dizziness, nausea, otalgia, otorrhea, tinnitus, and hearing loss in both ears for 3 weeks. Physical examination revealed edema in the tympanic membrane and external ear canal, and pain by palpation in the mastoid area bilaterally. There was no nystagmus, and the rest of the physical examination was otherwise normal. Temporal bone high resolution computed tomography (CT showed a lesion causing erosion in the mastoid cortex, tegmen tympani, ossicles, and in the bone covering the sigmoid sinus bilaterally. There was also erosion in the superior semicircular canal and petrous bone on the left side. Cortical mastoidectomy was performed under general anesthesia. Histopathologic examination of the tissue revealed Langerhans cell histiocytosis (LCH. In this paper a case with LCH, presenting with bilateral mastoid involvement which has been rarely reported in the literature, is discussed with the existing literature.

    Choroidal osteoma is a an extremely rare (especially located bilaterally), benign, intraocular tumor, the type of choristoma. It occurs between 2-3 decades of life, women are particularly vulnerable. The main complication in 1/3 cases is a subretinal neovascularization which may cause bleeding. The gradually progressive decalcification develops within the tumour over time, which causes atrophy of the retinal pigment epithelium and Bruch's membrane deformity. The article presents a case of a 26-year-old woman with bilateral choroidal osteoma complicated by subretinal hemorrhage; the diagnosis was based on clinical examination (biomicroscopy and indirect ophthalmoscopy) as well as specialised tests including: ultrasonography, optical coherence tomography, and fluorescein angiography.

    Full Text Available The use of swines as an experimental model to correct rectus diastasis by laparoscopy is described on this article. The correction of this deformity was achieved by the plication of the posterior rectus sheath with the insertion of two trocars on the inferior abdominal fold. One trocar was placed in the midline whereas the other was inserted laterally to the right rectus muscle. A continuous suture was made on the posterior rectus sheath with 0-Polipropilene. This suture was anchored at the anterior rectus sheath under direct vision. An incision of all layers was performed on the flank and the abdominal wall was turned inside out so that the area of plication could be assessed and evaluated. The experimental model described showed to be feasible to demonstrate the correction of rectus diastasis by laparoscopy.O uso de suínos como modelo experimental para a correção de diástase de retos por laparoscopia é descrito no presente artigo. A correção desta deformidade foi obtida pela plicatura da aponeurose posterior dos retos pela inserção de dois trocares na prega abdominal inferior. Um trocar foi introduzido na linha média enquanto o outro foi inserido lateralmente ao músculo reto abdominal direito. Uma sutura contínua de polipropileno-0 foi realizada na aponeurose posterior. Esta sutura foi ancorada na aponeurose anterior do músculo reto sob visão direta. Uma incisão foi realizada em todos os planos na região do flanco e a parede abdominal foi evertida para visualização e avaliação da área onde fora realizada a plicatura na aponeurose anterior. O modelo experimental descrito mostrou-se factível em demonstrar a correção da diástase de retos por laparoscopia.

    Study Design Case report. Background Acute traumatic avulsion of the rectus abdominis and adductor longus is rare. Chronic groin injuries, often falling under the athletic pubalgia spectrum, have been reported to be more common. There is limited evidence detailing the comprehensive rehabilitation and return to sport of an athlete following surgical or conservative treatment of avulsion injuries of the pubis or other sports-related groin pathologies. Case Description A 29-year-old National Basketball Association player sustained a contact injury during a professional basketball game. This case report describes a unique clinical situation specific to professional sport, in which a surgical repair of an avulsed rectus abdominis and adductor longus was combined with a multimodal impairment- and outcomes-based rehabilitation program. Outcomes The patient returned to in-season competition at 5 weeks postoperation. Objective measures were tracked throughout rehabilitation and compared to baseline assessments. Measures such as the Copenhagen Hip and Groin Outcome Score and numeric pain-rating scale revealed progress beyond the minimal important difference. Discussion This case report details the clinical reasoning and evidence-informed interventions involved in the return to elite sport. Detailed programming and objective assessment may assist in achieving desired outcomes ahead of previously established timelines. Level of Evidence Therapy, level 4.

    To evaluate the mammographic and clinical features of bilateral breast cancer. We retrospectively reviewed clinical records(n=23) and mammograms (n=15) of 23 patients with bilateral breast cancer. Patients' age, location of the tumor and pathologic staging were determined from clinical records. Mammographic features were classified as spiculated mass, nonspiculated mass, mass with microcalcification, microcalcification only, asymmetric density, and normal. Of the 23 cases of bilateral breast cancer, 8(34.8%) were synchronous and 15(65.2%) were metachronous. Age at diagnosis of cancer in the first breast was between 27 and 59(mean 43) years ; there was no statistically significant difference in mean age between patients with synchronous and metachronous cancer. The mean interval between the diagnosis of each lesion of the metachronous pairs was 9.1 years. In 11 of 23 cases(48%), tumors were locaated in the same quadrant, and in the other 12 cases(52%), they were in different quadrant. At mammography, five of 15 metachronous cancers(33%) were similar in appearance and 10 pairs(67%) were different. In 4 of 23 cases(17%), cancer in the first breast was at stage 0 and stage 1, and in 13 of 23(57%), cancer in the second breast was at this same stage. In bilateral breast cancer, the two breasts frequently show different mammographic features. Cancer of the second breast was at an early stage; this suggest that regular examination and mammography are important and can allow early detection of contralateral breast cancer.

  15. Fast and Provably Accurate Bilateral Filtering.

    Science.gov (United States)

    Chaudhury, Kunal N; Dabhade, Swapnil D

    2016-06-01

    The bilateral filter is a non-linear filter that uses a range filter along with a spatial filter to perform edge-preserving smoothing of images. A direct computation of the bilateral filter requires O(S) operations per pixel, where S is the size of the support of the spatial filter. In this paper, we present a fast and provably accurate algorithm for approximating the bilateral filter when the range kernel is Gaussian. In particular, for box and Gaussian spatial filters, the proposed algorithm can cut down the complexity to O(1) per pixel for any arbitrary S . The algorithm has a simple implementation involving N+1 spatial filterings, where N is the approximation order. We give a detailed analysis of the filtering accuracy that can be achieved by the proposed approximation in relation to the target bilateral filter. This allows us to estimate the order N required to obtain a given accuracy. We also present comprehensive numerical results to demonstrate that the proposed algorithm is competitive with the state-of-the-art methods in terms of speed and accuracy. PMID:27093722

  1. "Ostrich sign" indicates bilateral vertebral artery dissection.

    Science.gov (United States)

    Rose, David Z; Husain, M Rizwan

    2012-11-01

    Vertebral artery dissections (VADs) comprise about 2% of ischemic strokes and can be associated with trauma, chiropractic manipulation, motor vehicle collisions, whiplash, amusement park rides, golfing, and other motion-induced injuries to the neck. We present a case of bilateral extracranial VAD as a complication of conducting an orchestra. To our knowledge, this has not been documented in the literature. Conceivably, vigorous neck twisting in an inexperienced, amateur conductor may place excessive rotational forces upon mobile portions of the verterbral arteries, tear the intima, deposit subintimal blood that extends longitudinally, and cause neck pain and/or posterior fossa ischemic symptoms. Magnetic resonance angiography examinations of axially oriented slices of bilateral VADs resemble the face of an ostrich. This observation is similar to the "puppy sign," in which bilateral internal carotid artery dissections resemble the face of a dog. Craniocervical dissections of either the carotid or vertebral arteries have the potential to form an aneurysm, cause artery-to-artery embolism, or completely occlude the parent artery, resulting in an ischemic stroke. Because bilateral VADs in axial magnetic resonance angiographic sections stand out like the eyes of an ostrich, and because the fast identification of VADs is so critical, we eponymize this image the "ostrich sign."

    The aim of this study was to check whether there was a correlation between the value of the maximum developed torque of the quadriceps femoris muscle and subjective evaluation of a patient's pain which is measured by the VAS. Also evaluated were changes in the muscle torque value and KSS scale over time. For examining patient's condition use was made of a KSS scale (knee score: pain, range of motion, stability of joint and limb axis) before the surgery and in weeks 6 and 12, as well as 6 months after surgery. It was found to be constantly improving in comparison with the condition before the surgery. This is confirmed by a significant statistical value difference of KSS scale. The surgery substantially increases the quality of live and function recurrence.

    Obturator hernia (OH), a rare type of hernia, is associated with high morbidity and mortality. Diagnosis is often delayed as clinical symptoms are typically non-specific. OH is frequently associated with other occult inguinopelvic herniae. Early diagnosis is vital to decrease morbidity and mortality. We report the case of a 75-year-old woman who presented to the surgical outpatients' department with non-specific bilateral groin pain radiating to the thighs. CT of the pelvis demonstrated bilateral OH with no radiological evidence of bowel obstruction. Semiurgent elective laparoscopic total extraperitoneal mesh repair was performed. Intraoperative findings confirmed bilateral obturator herniae as well as incidental bilateral femoral herniae. This case highlights the need for a high index of suspicion for such concomitant hernias that, in the presence of OH, may only be identified intraoperatively. PMID:27113790

    2015-01-01

    Full Text Available Bilateral facial paralysis caused by bilateral temporal bone fracture is a rare clinical entity, with seven cases reported in the literature to date. In this paper, we describe a 40-year-old male patient with bilateral facial paralysis and hearing loss that developed after an occupational accident. On physical examination, House-Brackmann (HB facial paralysis of grade 6 was observed on the right side and HB grade 5 paralysis on the left. Upon temporal bone computed tomography (CT examination, a fracture line exhibiting transverse progression was observed in both petrous temporal bones. Our patient underwent transmastoid facial decompression surgery of the right ear. The patient refused a left-side operation. Such patients require extensive monitoring in intensive care units because the presence of multiple injuries means that facial functions are often very difficult to evaluate. Therefore, delays may ensue in both diagnosis and treatment of bilateral facial paralysis.

  7. Hardware Implementation of a Bilateral Subtraction Filter

    2009-01-01

    A bilateral subtraction filter has been implemented as a hardware module in the form of a field-programmable gate array (FPGA). In general, a bilateral subtraction filter is a key subsystem of a high-quality stereoscopic machine vision system that utilizes images that are large and/or dense. Bilateral subtraction filters have been implemented in software on general-purpose computers, but the processing speeds attainable in this way even on computers containing the fastest processors are insufficient for real-time applications. The present FPGA bilateral subtraction filter is intended to accelerate processing to real-time speed and to be a prototype of a link in a stereoscopic-machine- vision processing chain, now under development, that would process large and/or dense images in real time and would be implemented in an FPGA. In terms that are necessarily oversimplified for the sake of brevity, a bilateral subtraction filter is a smoothing, edge-preserving filter for suppressing low-frequency noise. The filter operation amounts to replacing the value for each pixel with a weighted average of the values of that pixel and the neighboring pixels in a predefined neighborhood or window (e.g., a 9 9 window). The filter weights depend partly on pixel values and partly on the window size. The present FPGA implementation of a bilateral subtraction filter utilizes a 9 9 window. This implementation was designed to take advantage of the ability to do many of the component computations in parallel pipelines to enable processing of image data at the rate at which they are generated. The filter can be considered to be divided into the following parts (see figure): a) An image pixel pipeline with a 9 9- pixel window generator, b) An array of processing elements; c) An adder tree; d) A smoothing-and-delaying unit; and e) A subtraction unit. After each 9 9 window is created, the affected pixel data are fed to the processing elements. Each processing element is fed the pixel value for

    Upper extremity hemiparesis is the most common post-stroke disability. Longitudinal studies have indicated that 30-66% of stroke survivors do not have full arm function 6 months post-stroke. The current gold standard for treatment of mild post-stroke upper limb impairment is constraint-induced therapy but, because of the inclusion criteria, alternative treatments are needed which target more impaired subjects. Bilateral arm training has been investigated as a potential rehabilitation intervention. Bilateral arm training encompasses a number of methods including: (1) bilateral isokinematic training; (2) mirror therapy using bilateral training; (3) device-driven bilateral training; and (4) bilateral motor priming. Neural mechanisms mediating bilateral training are first reviewed. The key bilateral training studies that have demonstrated evidence of efficacy will then be discussed. Finally, conclusions are drawn concerning clinical implications based on the reviewed literature. PMID:19517519

    Full Text Available Purpose: To report the clinical, confocal scan, and histopathologic features of Nocardia keratitis in a patient who developed bilateral infection following photorefractive keratectomy (PRK. Case Report: A 23-year-old woman underwent bilateral PRK for low myopia. On postoperative day 3, dense central stromal infiltrates were noticed in both eyes. Empirical antibiotic therapy was initiated which was converted into specific therapy after a definite diagnosis was made based on clinical features and confirmed by confocal scan and histopathologic findings. Clinical and confocal scan features were consistent with the diagnosis of Nocardia keratitis, and topical 2% amikacin eye drops were started. Because of poor response to medical therapy, lamellar keratectomy was performed in both eyes which shortened the treatment course. Histopathologic examination reconfirmed the initial diagnosis. Conclusion: Familiarity with clinical and confocal scan features facilitates early diagnosis of Nocardia keratitis leading to proper management and hence a rapid therapeutic response.

    Full Text Available 【Abstract】There is a dearth of case reports de-scribing simultaneous bilateral patellar tendon ruptures in the medical literature. These ruptures are often associated with systemic disorders such as lupus erythematosus or chronic steroid use. The author describes a case of a 24-year-old man who sustained traumatic bilateral patellar ten-don ruptures without any history of systemic disease or steroidal medication. We repaired and reattached the rup-tured tendons to the patella and augmented our procedure with allogeneic tendon followed by wire loop reinforcement. One year after operation, the patient regained a satisfactory range of motion of both knees with good quadriceps strength and no extensor lag. The recurrent microtrauma from a history of intense sports activity and a high body mass index may have played an important role in this trauma event.

    2009-11-01

    Full Text Available We present the case of a 45-year-old female who presented multiple times to the emergency department with acute low back pain and was subsequently diagnosed with bilateral psoas muscle abscess. Psoas abscess is an uncommon cause of acute low back pain that is associated with high morbidity and mortality. The onset of symptoms is frequently insidious and the clinical presentation vague. Proper diagnosis requires vigilance of the physician to recognize signs in the history and physical examination that are suggestive of a potentially serious spinal condition and initiate further workup. While most patients with acute low back pain have a benign etiology, this case report demonstrates the challenge of diagnosing a patient with bilateral psoas abscess who had few known risk factors and symptoms typical of mechanical low back pain.[West J Emerg Med. 2009;10(4:288-291.

    To determine the frequency and causes of bilateral ocular trauma. All patients coming to the hospital with bilateral eye trauma and requiring admission were recruited into the study. The details of patients demographics, risk factors, ocular examination, treatment offered and final visual acuity were noted and described as frequency and percentages. Out of a total of 1551 patients of hospitalized ocular trauma, 46 (2.9%, 92 eyes) had bilateral ocular trauma. The majority (54.3%) were due to landmine blast injuries followed by dynamite blast in 10.8%, coalmine blast and firearm injury in 6.5% each. Pressure cooker explosion and road traffic accident was the cause in 4.3% each. Gas cylinder and automobile battery explosion, alkali and acid burn, assault and incidental trauma occurred in 2.1%. Sixty three percent were between 16 and 40 years of age. Males were affected in 93.4%. Corneal and / or scleral repair was done in 58.6%, conjunctival and or corneal foreign body removal in 26% and extracapular cataract extraction with intraocular lens implantation in 16.3%. The visual acuity was in the range of 6/60 and perception of light in 54.3%, while in 21.7%, there was no perception of light at the time of admission. Due to severity of injury, the final visual acuity was poor and only 28.2% regained vision between 6/18 and 6/60. In this series, landmine, dynamite and coalmine blasts were the major causes of bilateral ocular trauma. Victims were usually young males. Due to severity of ocular trauma, majority had poor visual outcome. (author)

    Pregnancy luteoma is a non-neoplastic lesion of the ovary occurring during pregnancy and is usually discovered incidentally at the time of a cesarean section or during postpartum tubal ligation. An accurate diagnosis is important for the mother and the fetus as it can be confused with ovarian malignancy leading to unnecessary surgery. We report a case of a pregnant female who was discovered to have bilateral enlarged ovaries at the time of emergency cesarean section.

    The well-known bilateral filter is used to smooth noisy images while keeping their edges. This filter is commonly used with Gaussian kernel functions without real justification. The choice of the kernel functions has a major effect on the filter behavior. We propose to use exponential kernels with L1 distances instead of Gaussian ones. We derive Stein's Unbiased Risk Estimate to find the optimal parameters of the new filter and compare its performance with the conventional one. We show that t...

    Full Text Available Aspergillus endophthalmitis is a devastating inflammatory condition of the intraocular cavities that may result in irreparable loss of vision and rapid destruction of the eye. Almost all cases in the literature have shown an identified source causing aspergillus endophthalmitis as a result of direct extension of disease. We present a rare case of bilateral aspergillus endophthalmitis. A 72-year-old woman with a history of diabetes mellitus, congenital Hirschsprung disease, and recent culture-positive candida pyelonephritis with hydronephrosis status post-surgical stent placement presented with difficulty opening her eyes. She complained of decreased vision (20/200 with pain and redness in both eyes – right worse then left. Examination demonstrated multiple white fungal balls in both retinas consistent with bilateral fungal endophthalmitis. Bilateral vitreous taps for cultures and staining were performed. Patient was given intravitreal injections of amphotericin B, vancomycin, ceftazidime, and started on oral fluconazole. Patient was scheduled for vitrectomy to decrease organism burden and to remove loculated areas of infection that would not respond to systemic antifungal agents. Four weeks after initial presentation, the fungal cultures revealed mold growth consistent with aspergillus. Patient was subsequently started on voriconazole and fluconazole was discontinued due to poor efficacy against aspergillus. Further workup was conducted to evaluate for the source of infection and seeding. Transthoracic cardiogram was unremarkable for any vegetation or valvular abnormalities. MRI of the orbits and sinuses did not reveal any mass lesions or bony destruction. CT of the chest was unremarkable for infection. Aspergillus endophthalmitis may occur because of one of these several mechanisms: hematogenous dissemination, direct inoculation by trauma, and contamination during surgery. Our patient's cause of bilateral endophthalmitis was through an

    Brodie's abscess is a form of subacute osteomyelitis, which typically involves the metaphyses of the long tubular bones, particularly in the tibia. The diagnosis is usually made incidentally, as there are no accompanying symptoms or laboratory studies. Bilateral involvement at the proximal tibia is unusual. However, orthopaedic surgeons should be aware of this entity, as it may present without symptoms. Checking the contralateral limb for concomitant Brodie's abscess is recommended.

    2008-06-05

    Image smoothing is a fundamental operation in computer vision and image processing. This work has two main thrusts: (1) implementation of a bilateral filter suitable for use in smoothing, or denoising, 3D volumetric data; (2) implementation of the 3D bilateral filter in three different parallelization models, along with parallel performance studies on two modern HPC architectures. Our bilateral filter formulation is based upon the work of Tomasi [11], but extended to 3D for use on volumetric data. Our three parallel implementations use POSIX threads, the Message Passing Interface (MPI), and Unified Parallel C (UPC), a Partitioned Global Address Space (PGAS) language. Our parallel performance studies, which were conducted on a Cray XT4 supercomputer and aquad-socket, quad-core Opteron workstation, show our algorithm to have near-perfect scalability up to 120 processors. Parallel algorithms, such as the one we present here, will have an increasingly important role for use in production visual analysis systems as the underlying computational platforms transition from single- to multi-core architectures in the future.

    We report here a case study of a rare neurological patient with bilateral brain damage encompassing a substantial portion of the so-called “limbic system.” The patient, Roger, has been studied in our laboratory for over 14 years and the current article presents his complete neuroanatomical and neuropsychological profiles. The brain damage occurred in 1980 following an episode of herpes simplex encephalitis. The amount of destroyed neural tissue is extensive and includes bilateral damage to core limbic and paralimbic regions, including the hippocampus, amygdala, parahippocampal gyrus, temporal poles, orbitofrontal cortex, basal forebrain, anterior cingulate cortex, and insular cortex. The right hemisphere is more extensively affected than the left, although the lesions are largely bilateral. Despite the magnitude of his brain damage, Roger has a normal IQ, average to above average attention, working memory, and executive functioning skills, and very good speech and language abilities. In fact, his only obvious presenting deficits are a dense global amnesia and a severe anosmia and ageusia. Roger's case presents a rare opportunity to advance our understanding of the critical functions underlying the human limbic system, and the neuropsychological and neuroanatomical data presented here provide a critical foundation for such investigations.

  16. Bilateral femoral neck fractures following pelvic irradiation

    International Nuclear Information System (INIS)

    Over 300 cases of femoral neck fractures following radiotherapy for intrapelvic malignant tumor have been reported in various countries since Baensch reported this disease in 1927. In Japan, 40 cases or so have been reported, and cases of bilateral femoral neck fractures have not reached to ten cases. The authors experienced a case of 75 year-old female who received radiotherapy for cancer of the uterus, and suffered from right femoral neck fracture 3 months after and left femoral neck fracture one year and half after. As clinical symptoms, she had not previous history of trauma in bilateral femurs, but she complained of a pain in a hip joint and of gait disturbance. The pain in left femoral neck continued for about one month before fracture was recognized with roentgenogram. As histopathological findings, increase of fat marrow, decrease of bone trabeculae, and its marked degeneration were recognized. Proliferation of some blood vessels was found out, but thickness of the internal membrane and thrombogenesis were not recognized. Treatment should be performed according to degree of displacement of fractures. In this case, artificial joint replacement surgery was performed to the side of fracture of this time, because this case was bilateral femoral neck fractures and the patient had received artificial head replacement surgery in the other side of fracture formerly.

    The current international energy trade governance system is fragmented and multi-layered. Streamlining it for greater legal cohesiveness and international political and economic cooperation would promote global energy security. The current article explores three levels of energy trade governance: multilateral, regional and bilateral. Most energy-rich countries are part of the multilateral trading system, which is institutionalized by the World Trade Organization (WTO). The article analyzes the multilateral energy trade governance system by focusing on the WTO and energy transportation issues. Regionally, the article focuses on five major regional agreements and their energy-related aspects and examines the various causes that explain the proliferation of regional trade agreements, their compatibility with WTO law, and then provides several examples of regional energy trade governance throughout the world. When it comes to bilateral energy trade governance, this article only addresses the European Union’s (EU) bilateral energy trade relations. The article explores ways in which gaps could be filled and overlaps eliminated whilst remaining true to the high-level normative framework, concentrating on those measures that would enhance EU energy security.

  18. Bilateral spontaneous rupture of 'hale' kidneys

    International Nuclear Information System (INIS)

    A rare case of spontaneous bilateral rupture of the kidneys, occurring consecutively over a one-year period in a young male patient with 'hale' kidneys until then, is described. The patient's past history and thorough examination performed do not justify to assign the case under the heading of some of the etiological factors as the underlying cause of spontaneous kidney rupture. The literature survey on spontaneous bilateral non-tumor ruptures of kidneys shows that over a 20-year period, only 3 cases of bilateral spontaneous ruptures have been reported. It is pointed out that panarteritis nodosa followed by hemorrhagic fever with renal syndrome is the commonest underlying cause of such ruptures. Clinically spontaneous ruptures become manifest with emergency condition presenting severe renal colic, impaired to serious general condition, often with acute abdomen and hemodynamic breakdown, and no past history evidence of renal disease or injury. In the initial phase diagnosing is not always easy; it is usually made on the ground of physical examination and the full range of imaging studies used in urological practice and during operative treatment. Emphasis is laid on the fact that the imaging methods are not invariably sufficient to identify the exact etiological factor giving rise to such a severe condition, but nevertheless these methods have an essential practical bearing on diagnosing a rupture.

    Full Text Available Nasolabial cysts are painless, submucosal, non-odontogenic jaw cysts presenting as soft tissue swellings in the maxillary anterior mucolabial fold lateral to midline, leading to elevation of nasal ala. Present case documents bilateral nasolabial cysts in a 69-year-old Asian female patient. In the present case, extraoral swelling of maxillary lip and elevation of nasal ala was observed on right side of the face. Intraorally, soft and fluctuant bilateral cysts were observed. Straw-colored fluid was aspirated from the right cyst. Radiographically, erosion of bone in a "cupping" fashion was observed in the region of left cyst. The cysts were enucleated using intraoral approach. Histopathology of the right-sided cyst revealed a cystic cavity lined by stratified squamous cells along with a few mucosal cells. At few places, stratified squamous and pseudostratified columnar epithelia with many cilia and goblet cells were also evident. Capsule was loosely arranged with fibrous tissue and chronic inflammatory infiltrate. Left-sided cystic specimen showed two or more layered stratified squamous lining epithelium with thin capsule. Diagnosis of bilateral nasolabial/nasoalveolar cysts was confirmed.

    Full Text Available This article focuses on issues related to the identification and investigation of the lymph node metastases with bilateral breast cancer. The presence of metastases in the lymph nodes determines the stage of the disease, and introducing a form of tumor progression, characterizes the course and prognosis for the future in a specific patient. Thus, the identification of possible morphological and immunohistochemical characteristics of the tumor tissue and their comparison with the frequency and severity of regional lymph nodes would help to solve the problem of the identification of prognostic factors and markers associated with the risk of nodal metastasis in bilateral breast cancer. This work is relevant due to the fact that the literature on this issue to date are treated ambiguously, and answers to many questions, unfortunately, no.The authors performed a morphological study of the tumor tissue from 600 patients suffering from unilateral and bilateral breast cancer. To avoid false results were studied only cases corresponding to the histological type of invasive carcinoma of non-specific type. The study found that a greater number and a greater percentage of the affected lymph node metastases were observed in patients with bilaterally synchronous tumors. The patients of this group of metastatic lymph nodes was detected more frequently in the presence of infiltrative component of three or more types of structures with the presence of these discrete groups of tumor cells, and the observed maximum degree of inflammatory infiltration of the tumor stroma. In the group of patients with unilateral breast cancer nodal metastasis often detects when triple negative molecular genetic type of the lesion, with large amounts of tumor site, in the presence of infiltrative component of three or more types of structures with the obligatory presence of these microalveolar structures and discretely spaced groups of tumor cells and the highest severity of

    Full Text Available OBJECTIVE: to evaluate the role of fibrillar extracellular matrix components in the pathogenesis of inguinal hernias. METHODS: samples of the transverse fascia and of the anterior sheath of the rectus abdominis muscle were collected from 40 men aged between 20 and 60 years with type II and IIIA Nyhus inguinal hernia and from 10 fresh male cadavers (controls without hernia in the same age range. The staining technique was immunohistochemistry for collagen I, collagen III and elastic fibers; quantification of fibrillar components was performed with an image analysis processing software. RESULTS: no statistically significant differences were found in the amount of elastic fibers, collagen I and collagen III, and the ratio of collagen I / III among patients with inguinal hernia when compared with subjects without hernia. CONCLUSION: the amount of fibrillar extracellular matrix components did not change in patients with and without inguinal hernia.

    The paper examines the impact of two main instruments of economic diplomacy — regional integration and commercial diplomacy on export flows among African states. We test whether there is any evidence of a trade-off or complementary interaction between these two instruments in trade facilitation. We...... compare the effects of these two instruments of economic diplomacy on bilateral trade by employing a gravity model for 45 African states over the period 1980-2005. The results show that bilateral diplomatic exchange is a relatively more significant determinant of bilateral exports among African states...... that there exists a trade-off between regional integration and commercial diplomacy in facilitating exports or a lack of complementarity between these two instruments of economic diplomacy....

    Full Text Available The aim of the present work was to evaluate the effect of stocking density on the biceps femoris (BF muscle fibre properties, meat quality, the growth performance and carcass traits of Czech White rabbits.  A total of 20 rabbits (40 days old, 10 rabbits per treatment, sex ratio 1/1 were reared in cages at different stocking densities (10 rabbits/m2 or 4 rabbits/m2 for 49 days. Stocking density had no significant effect on the growth performance. There were no significant differences between groups with regard to hot carcass weight (HCW or dressing-out percentage. The proportions of both perirenal (9.5 vs. 15.9 g/kg HCW; P=0.010 and total dissectible fat (14.9 vs. 25.1 g/kg HCW; P=0.001 were lower in rabbits reared at the lower stocking density. No significant differences in ultimate pH values, meat colour or proximate composition were observed. The hind leg meat of rabbits reared at the lower stocking density contained significantly less lauric (4.6 vs. 6.7 mg/100 g of muscle; P=0.008 and myristic acid (52.2 vs. 64.4 mg/100 g of muscle; P=0.033. Significantly higher percentages of βR fibres (16.3 vs. 6.5 %, P=0.001 and αR fibres (24.5 vs. 14.2 %; P=0.001 and a significantly lower percentage of αW fibres (59.2 vs. 79.3 %; P=0.001 were also observed in these rabbits. The mean cross-sectional area (1882 vs. 2744 μm2; P=0.001 and diameter (47.9 vs. 58.5 μm; P=0.001 of βR fibres were smaller in rabbits reared at the lower stocking density. Thus, the lower stocking density favourably affected the medium-chain fatty acid profile of meat and fibre characteristics of the rabbits' biceps femoris muscle.

    Full Text Available Context: Anatomical localization of pituitary adenoma can be challenging in adrenocorticotropic hormone (ACTH-dependent Cushing's syndrome, and bilateral inferior petrosal sinus sampling (BIPSS is considered gold standard in this regard. Stimulation using corticotrophin-releasing hormone (CRH improves the sensitivity of BIPSS, however, same is not easily available in India. Therefore, we undertook this study of BIPPS using vasopressin as agent for stimulation owing to its ability to stimulate V3 receptors present on corticotrophs. Aims: To study the tumor localization and lateralization in difficult to localize cases of ACTH-dependent Cushing's syndrome by bilateral inferior petrosal sinus sampling using vasopressin for corticotroph stimulation. Settings and Design: Prospective observational study. Subjects and Methods: Six patients (5 females meeting inclusion criteria underwent BIPSS using vasopressin for stimulation. Results: All six patients had nonsuppressible overnight and low dose dexamethasone suppression test with elevated plasma ACTH levels suggestive of ACTH-dependent Cushing's syndrome. High dose dexamethasone suppression test showed suppressible cortisol in two cases, and microadenoma was seen in two patients on magnetic resonance imaging pituitary. Contrast enhanced computed tomography of the abdomen showed left adrenal hyperplasia in one case and anterior mediastinal mass with bilateral adrenal hyperplasia another. Using BIPSS four patients were classified as having Cushing's disease that was confirmed histopathologically following surgery. Of the remaining two, one had primary pigmented nodular adrenocortical disease, and another had thymic carcinoid with ectopic ACTH production as the cause of Cushing's syndrome. No serious adverse events were noted. Conclusions: Vasopressin may be used instead of CRH and desmopressin for stimulation in BIPSS.

    The aim of this study was to describe and compare the EMG patterns of select lower limb muscles throughout the golf swing, performed with three different clubs, in non-elite middle-aged players. Fourteen golfers performed eight swings each using, in random order, a pitching wedge, 7-iron and 4-iron. Surface electromyography (EMG) was recorded bilaterally from lower limb muscles: tibialis anterior, peroneus longus, gastrocnemius medialis, gastrocnemius lateralis, biceps femoris, semitendinosus, gluteus maximus, vastus medialis, rectus femoris and vastus lateralis. Three-dimensional high-speed video analysis was used to determine the golf swing phases. Results showed that, in average handicap golfers, the highest muscle activation levels occurred during the Forward Swing Phase, with the right semitendinosus and the right biceps femoris muscles producing the highest mean activation levels relative to maximal electromyography (70-76% and 68-73% EMG(MAX), respectively). Significant differences between the pitching wedge and the 4-iron club were found in the activation level of the left semitendinosus, right tibialis anterior, right peroneus longus, right vastus medialis, right rectus femuris and right gastrocnemius muscles. The lower limb muscles showed, in most cases and phases, higher mean values of activation on electromyography when golfers performed shots with a 4-iron club. PMID:26197882

    This study aimed to determine fatty acid (FA) composition of Longissimus dorsi (LD) and Biceps femoris (BF) muscles of an Iranian indigenous goat (Lori goat) at two live weights at slaughter (LWS). Twenty male Lori goats (5 to 8 months) raised in nomadic system were slaughtered either at LWS less than 20 kg (light) or LWS more than 30 kg (heavy). Carcass dressing and FA composition of intramuscular fat of LD and BF muscles as well as cholesterol content of LD muscle were determined. Heavy goats had higher dressing percentage than light ones (42.7vs.39.3%, P goats (P goats were 71.2 ± 16 and 59.5 ± 14 mg per 100 g fresh meat respectively. In conclusion, desirable PUFA/SFA (0.6) and n-3/n-6 ratio (3.8) found in indigenous Lori goat propose healthy source of lean meat for the consumers. PMID:26431711

    Fatty acid composition of neutral lipids (NLs), phospholipids (PLs) and free fatty acids (FFAs) from intramuscular fat (IMF), lipid oxidation and lipase activity in muscle Semimembranosus (SM) and msucle Biceps femoris (BF) of dry-cured Xuanwei ham during the 90-d salting stages were analysed. The salt content increased from 0.34 to 3.52%in BF and from 0.10 to 5.42%in SM during the 90 d salting stage, respectively. PLs of IMF in both BF and SM decreased 54.70%(P<0.001) and 34.64%(P<0.05), furthermore, the saturated fatty acids (SFA), monounsaturated fatty acids (MUFA) and polyunsaturated fatty acids (PUFA) of PLs in both muscles were hydrolysed almost isochronously. FFAs were increased from 0.46 g 100 g-1 lipids to 2.92 g 100 g-1 lipids in BF at the end of salting, which was lower than SM (from 1.29 g 100 g-1 lipids to 9.70 g 100 g-1 lipids). The activities of acid lipase, neutral lipase and acid phospholipase all remained active in the 90 d. The thiobarbituric acid reactive substances (TBARS) was slowly increased to 1.34 mg kg-1 muscle in BF and to 2.44 mg kg-1 muscle in SM during the salting stage. In conclusion, the controlled salting process prompted the hydrolysis of PLs of IMF notably and increased the lipid oxidation of muscles within some limits.

    2010-09-01

    Full Text Available Introduction: Electrical stimulation has been used for many years in rehabilitation medicine to prevent atrophy or to increase muscle strength, but the use of electrical stimulation for muscle strengthening in research and clinical practice has become increasingly popular in recent years. The quadriceps femoris is the thigh muscle group that suffers the greatest amount of atrophy. This study aimed to compare the effects of electrical stimulation and voluntary isometric contraction for increasing the quadriceps strength and the girth of thigh in middle aged and old patients after removal of cast immobilization. Methods: 87 patients whose knees were immobilized following lower extremity fracture were randomly allocated into two groups: the electrical stimulation and voluntary isometric exercise group. The patients trained for 20 minutes, 3 days a week over a period of 6 weeks. The subject's thigh circumference and muscle power were evaluated before and after treatment. Results: The increase in quadriceps strength of the electrical stimulation group (28% was significantly less than that of voluntary isometric exercise group (40%. However, there was no significant difference between the two treatment modalities in increasing circumference of thigh (1.42 ± 0.27 & 1.41 ±0.36, P=0.96. Conclusion: This study showed that although electrical stimulations is an alternative and potentially effective means to increase the strength of quadriceps following knee immobilization in middle-aged and old patients, it is not more effective than voluntary isometric exercise.

    Front, full, and parallel squats are some of the most popular squat variations. The purpose of this investigation was to compare mean and peak electromyography (EMG) amplitude of the upper gluteus maximus, lower gluteus maximus, biceps femoris, and vastus lateralis of front, full, and parallel squats. Thirteen healthy women (age = 28.9 ± 5.1 y; height = 164 ± 6.3 cm; body mass = 58.2 ± 6.4 kg) performed 10 repetitions of their estimated 10-repetition maximum of each respective variation. There were no statistical (P ≤ .05) differences between full, front, and parallel squats in any of the tested muscles. Given these findings, it can be concluded that the front, full, or parallel squat can be performed for similar EMG amplitudes. However, given the results of previous research, it is recommended that individuals use a full range of motion when squatting, assuming full range can be safely achieved, to promote more favorable training adaptations. Furthermore, despite requiring lighter loads, the front squat may provide a similar training stimulus to the back squat.

    Bridging exercise variations are well researched and commonly employed for both rehabilitation and sport performance. However, resisted bridge exercise variations have not yet been compared in a controlled experimental study. Therefore, the purpose of this study was to compare the differences in upper and lower gluteus maximus, biceps femoris, and vastus lateralis electromyography (EMG) amplitude for the barbell, band, and American hip thrust variations. Thirteen healthy female subjects (age = 28.9 y; height = 164.3 cm; body mass = 58.2 kg) familiar with the hip thrust performed 10 repetitions of their 10-repetition maximum of each variation in a counterbalanced and randomized order. The barbell hip thrust variation elicited statistically greater mean gluteus maximus EMG amplitude than the American and band hip thrusts, and statistically greater peak gluteus maximus EMG amplitude than the band hip thrust (P ≤ .05), but no other statistical differences were observed. It is recommended that resisted bridging exercise be prescribed according to the individual's preferences and desired outcomes.

    Full Text Available This is a report of one case of bilateral acetabular rim fracture in association with femoroacetabular impingement (FAI, which was treated with a hip arthroscopic procedure, performing a partial resection, a labral reinsertion, and a subsequential internal fixation with cannulated screws. Up to date, there are in the literature only two reports of rim fracture and “os acetabuli” in association with FAI. In the case we present, the pincer and cam resection were performed without complications; the technique used was published previously. With this technique the head of the screw lays hidden by the reattached labrum. We removed partially the fractured rim fragment and the internal fixation of the remaining portion was achieved with a screw. In the event of a complete resection of the fragment, it would have ended with a LCE angle of 18° and a high probability of hip instability. We believe that this bilateral case helps establish the efficacy and reproducibility of the technique described by Larson.

    antecedentes: el cáncer de mama en el hombre es una enfermedad con baja incidencia, que se reduce aún más cuando es bilateral sincrónica. Existen pocas publicaciones en los últimos años. Objetivo: establecer pautas para el tratamiento de este cáncer, aunque sea infrecuente. Caso clínico: paciente masculino de 75 años de edad, con tumores en ambas mamas, que se le resecaron completamente con exéresis de ganglios palpables. El estudio histopatológico informó que se trataba de un carcinoma ductal infiltrante no especificado. Se indicó tratamiento adyuvante con tamoxifeno y radioterapia; en la actualidad está libre de enfermedad. Conclusiones: el carcinoma mamario bilateral sincrónico en el varón es una enfermedad poco frecuente. Su tratamiento principal es la cirugía, de ahí la importancia del diagnóstico temprano. En la mayoría de los casos se requiere quimioterapia y radioterapia adyuvante porque suelen diagnosticarse en un estadio avanzado.

    Full Text Available To present a rare complication, such as bilateral cataracts, in a man who sustained a high-voltage electrical injury. A 35- year-old man was admitted with a complaint of decrease in visual acuity. He had a history of a contact with a power line carrying 30.000 volts of electricity while working at a construction site. Examination at a burn center revealed second-degree facial, neck and left foot burns. One month later, the patient underwent amputation of fourth and fifth toes of his left foot. During the next 6 months, he noted decreasing vision in both eyes. Ocular examination 1 year after the accident revealed that the patient’s visual acuity had deteriorated to 1/10 in both eyes. The cornea on the left eye showed superficial punctate opacities. The lenses in both eyes had anterior subcapsular cortical lens opacities and posterior subcapsular opacities. Uncomplicated bilateral phacoemulsification surgery with intraocular lens implantation was performed and the patient’s visual acuity returned to 10/10 in both eyes. We noted that the fundus remained normal in both eyes. Electrical cataracts are still a serious potential complication that may occur after electrical injury. Awareness of this by burn team members is important for providing optimal treatment to those who have suffered an electrical injury. (Turk J Ophthalmol 2011; 41: 197-9

    Background. Despite advances in surgical repair of hiatus hernias, there remains a high radiological recurrence rate. We performed a novel technique incorporating bilateral oesophageal fixation and evaluated outcomes, principally symptom improvement and hernia recurrence. Methods. A retrospective study was performed on a prospective database of patients undergoing hiatus hernia repair with bilateral oesophageal fixation. Retrospective and prospective quality of life (QOL), PPI usage, and patient satisfaction data were obtained. Hernia recurrence was assessed by either barium swallow or gastroscopy. Results. 87 patients were identified in the database with a minimum of 3 months followup. There were significant improvements in QOL scores including GERD HRQL (29.13 to 4.38, P < 0.01), Visick (3 to 1), and RSI (17.45 to 5, P < 0.01). PPI usage decreased from a median of daily to none, and there was high patient satisfaction (94%). 57 patients were assessed for recurrence with either gastroscopy or barium swallow, and one patient had evidence of recurrence on barium swallow at 45 months postoperatively. There was an 8% complication rate and no mortality or oesophageal perforation. Conclusions. This study demonstrates that our technique is both safe and effective in symptom control, and our recurrence investigations demonstrate at least short term durability. PMID:26065030

Although his general condition improved after intravenous acyclovir administration, the patient presented with visual loss in both eyes 4 days after admission. Visual acuity in his right eye was 20/200 and his left eye had light perception alone. Both eyes showed panretinal arteritis diagnosed as acute retinal necrosis. Panretinal photocoagulation was performed for both eyes. Progression of retinal detachment was prevented in both eyes; however, visual acuity of the left eye was totally lost because of neovascular glaucoma. Visual acuity of the right eye recovered to 20/20.Conclusion: Although cases of bilateral acute retinal necrosis have been reported after herpetic encephalitis, this condition is rare after herpetic meningitis. Prophylactic acyclovir therapy and early panretinal photocoagulation may prevent retinal detachment and improve the prognosis. Neurologists and ophthalmologists should be aware that not only herpetic encephalitis but also herpetic meningitis can lead to acute retinal necrosis within a very short interval.Keywords: acute retinal necrosis, herpetic meningitis, herpes simplex, varicella zoster virus

    The paper presents the results of gait parameters as a function of unilateral weight. The object of the research was a woman walking on a stationary surface and carrying in his hand weights from 0 to 15 kg. Her movement was recorded by 6 cameras recording the location of 34 markers placed at appropriate points in the body. 3D reconstruction was performed for each of the reflecting markers. Tested signals were changes in the value the joint angles of ankle, knee and hip. On the basis of about 6 cycles of movement of each load, a model for the average gait cycle was developed. The result of the experiments are graphs of changes the joint angles as a function of time, bilateral cyclograms, synchronized bilateral cyclograms and regression lines. The conclusion of the study is to determine how one-sided load affects gait asymmetry. Simple and easy to interpret method of presentation of results were also shown. Studies were conducted using VICON system.

    Primary aldosteronism due to unilateral aldosterone-producing adenoma (APA) is a surgically curable form of hypertension. Bilateral APA can also be surgically curable in theory but few successful cases can be found in the literature. It has been reported that even using successful adrenal venous sampling (AVS) via bilateral adrenal central veins, it is extremely difficult to differentiate bilateral APA from bilateral idiopathic hyperaldosteronism (IHA) harbouring computed tomography (CT)-detectable bilateral adrenocortical nodules. We report a case of bilateral APA diagnosed by segmental AVS (S-AVS) and blood sampling via intra-adrenal first-degree tributary veins to localize the sites of intra-adrenal hormone production. A 36-year-old man with marked long-standing hypertension was referred to us with a clinical diagnosis of bilateral APA. He had typical clinical and laboratory profiles of marked hypertension, hypokalaemia, elevated plasma aldosterone concentration (PAC) of 45.1 ng dl(-1) and aldosterone renin activity ratio of 90.2 (ng dl(-1) per ng ml(-1 )h(-1)), which was still high after 50 mg-captopril loading. CT revealed bilateral adrenocortical tumours of 10 and 12 mm in diameter on the right and left sides, respectively. S-AVS confirmed excess aldosterone secretion from a tumour segment vein and suppressed secretion from a non-tumour segment vein bilaterally, leading to the diagnosis of bilateral APA. The patient underwent simultaneous bilateral sparing adrenalectomy. Histopathological analysis of the resected adrenals together with decreased blood pressure and PAC of 5.2 ng dl(-1) confirmed the removal of bilateral APA. S-AVS was reliable to differentiate bilateral APA from IHA by direct evaluation of intra-adrenal hormone production. PMID:26538381

  8. The bilateral advantage for famous faces: interhemispheric communication or competition?

    2008-04-01

    The bilateral advantage for the perception of famous faces was investigated using a redundant target procedure. In experiment 1 we compared simultaneous presentation of stimuli (a) bilaterally and (b) one above the other in the central field. Results showed a redundancy advantage, but only when faces were presented bilaterally. This result lends support to the notion of interhemispheric communication using cross-hemisphere representations. Experiment 2 examined the nature of such communication by comparing bilateral presentation of identical face images, with bilateral presentation of different images of the same person. When asked to make a familiar/unfamiliar face judgement, participants showed evidence for a redundancy advantage under both bilateral conditions. This suggests that the nature of the information shared in interhemispheric communication is abstract, rather than being tied to superficial stimulus properties.

  9. The effect of different decline angles on the biomechanics of double limb squats and the implications to clinical and training practice

    Richards Jim

    2016-09-01

    Full Text Available Bilateral decline squatting has been well documented as a rehabilitation exercise, however, little information exists on the optimum angle of decline. The aim of this study was to determine the ankle and knee angle, moments, the patellofemoral joint load, patellar tendon load and associated muscle activity while performing a double limb squat at different decline angles and the implications to rehabilitation. Eighteen healthy subjects performed double limb squats at 6 angles of declination: 0, 5, 10, 15, 20 and 25 degrees. The range of motion of the knee and ankle joints, external moments, the patellofemoral/patellar tendon load and integrated EMG of gastrocnemius, tibialis anterior, rectus femoris and biceps femoris were evaluated. As the decline angle increased up to 20 degrees, the range of motion possible at the ankle and knee increased. The joint moments showed a decrease at the ankle up to 15 degrees and an increase at the knee up to 25 degrees, indicating a progressive reduction in loading around the ankle with a corresponding increase of the load in the patellar tendon and patellofemoral joint. These trends were supported by a decrease in tibialis anterior activity and an increase in the rectus femoris activity up to 15 degrees declination. However, gastrocnemius and biceps femoris activity increased as the decline angle increased above 15 degrees. The action of gastrocnemius and biceps femoris stabilises the knee against an anterior displacement of the femur on the tibia. These findings would suggest that there is little benefit in using a decline angle greater than 15-20 degrees unless the purpose is to offer an additional stability challenge to the knee joint.

    Full Text Available El colgajo musculocutáneo de recto abdominal transverso ha sido la técnica quirúrgica más utilizada en reconstrucción mamaria autógena. Proporciona una nueva mama con volumen adecuado, ptosis, aspecto natural y no requiere la implantación de prótesis, obteniéndose una buena simetría con la mama contralateral, que perdura en el tiempo. El inconveniente de esta técnica es la morbilidad de la pared abdominal. Este colgajo sacrifica el músculo y la vaina anterior del recto que puede tener consecuencias como hernias y eventraciones. Para minimizar este problema se desarrolló el colgajo de recto abdominal microquirúrgico, que sólo sacrifica una porción muscular, disminuyendo significativamente el número de secuelas. Como inconveniente presenta la dificultad de la técnica quirúrgica, requiriendo dominio de la microcirugía vasculonerviosa. En conclusión, se puede devolver a la mujer mastectomizada una nueva mama de forma completamente autógena, con volumen, forma y textura similares al lado sano que ayude, en definitiva, a recuperar la autoestima perdida.The transverse rectus abdominis musculocutaneous (TRAM flap has been the most employed technique in autogenous breast reconstruction. It provides a new breast of adequate volume, ptosis and natural appearance, and does not require the implantation of prosthesis; a good symmetry with the contralateral breast is obtained, which lasts over time. The drawback of this technique is the morbidity of the abdominal wall. This flap sacrifices the muscle and the anterior rectus sheath which can result in consequences such as hernias and eventrations. To minimise this problem the microsurgical TRAM flap was developed, which only sacrifices a portion of muscle, significantly reducing the number of sequels. A drawback is the difficulty of the surgical technique, which requires mastery of vascular-nervous microsurgery. In conclusion, a new breast can be returned to the mastectomised woman in a

    Full Text Available Marfan syndrome is an autosomal dominant systemic disorder of the connective tissue. Marfan syndrome affects most organs and tissues, especially the skeleton, lungs, eyes, heart, and the large blood vessels. Eye involvement may be in the form of retinal detachment which is a potentially dangerous manifestation for its sight threatening nature .We report a case where a 17 year old male developed sudden blindness due to spontaneous bilateral retinal detachment. Examination revealed features of Marfan syndrome and was stamped as a case of Marfan syndrome by Ghent criteria . The point to stress upon is that a young male developing spontaneous retinal detachment, a diagnosis of underlying Marfan syndrome should be kept in mind if appropriate clinical stigmata are present.

    Current models of bilateral trade neglect the effects of income distribution. This paper addresses the issue by accounting for non-homothetic consumer preferences and hence investigating the role of income distribution in the context of the gravity model of trade. A theoretically justified gravity model is estimated for disaggregated trade data (Dollar volume is used as dependent variable) using a sample of 104 exporters and 108 importers for 1980–2003 to achieve two main goals. We define and calculate new measures of income distribution similarity and empirically confirm that greater similarity of income distribution between countries implies more trade. Using distribution-based measures as a proxy for demand similarities in gravity models, we find consistent and robust support for the hypothesis that countries with more similar income-distributions trade more with each other. The hypothesis is also confirmed at disaggregated level for differentiated product categories. PMID:27137462

    Full Text Available Tuberculosis is an important cause of uveitis in our country. India has been declared the country with the highest tuberculosis burden with 25 % of the cases . (1 This is especially true in Andhra Pradesh and Telangana which have a high percentage of affected patients. However , tuberculous uveitis is usually a unilateral presen tation. We report a case of bilateral uveitis of tuberculous origin in a 55 year old woman. She presented with different tuberculous manifestations in the two eyes. While the RE showed non granulomatous uveitis with sclerosing keratitis , the LE showed gran ulomatous uveitis with mutton fat keratic precipitates. Systemic examination revealed an enlarged lymph node which was positive for tuberculosis on biopsy. She was hence diagnosed as extra pulmonary tuberculosis and was treated with ATT regimen. In this pa tient , uveitis was the initial manifestation and resulted in a systemic diagnosis.

    Bilateral adrenal hemorrhage (BAH) is a rare complication typically seen in critically ill patients, which can lead to acute adrenal insufficiency and death unless it is recognized promptly and treated appropriately. We describe the case of a 64-year-old man with polycythemia vera found to be unresponsive with fever, hypotension, tachycardia, and hypoglycemia. Electrocardiogram showed ST-elevation with elevated troponin, hemoglobin, prothrombin time, and partial thromboplastin time. He required aggressive ventilator and vasopressor support. Despite primary coronary intervention, he remained hypotensive. Random cortisol level was low. He received stress dose hydrocortisone with immediate hemodynamic stability. BAH was highly suspected and was confirmed by non-contrast abdominal computed tomography. Prompt recognition and timely initiated treatment remain crucial to impact the mortality associated with acute adrenal insufficiency. PMID:27609733

    2016-09-01

    This case demonstrates a rarely reported bilateral scapulohumeral bony ankylosis. A young woman developed extensive heterotopic ossifications (HOs) in both shoulder joints after being mechanically ventilated for several months at the intensive care unit in a comatose status. She presented with a severe movement restriction of both shoulder joints. Surgical resection of the bony bridges was performed in 2 separate sessions with a significant improvement of shoulder function afterwards. No postoperative complications, pain, or recurrence of HOs were noted at 1-year follow-up. Mechanical ventilation, immobilization, neuromuscular blockage, and prolonged sedation are known risk factors for the development of HOs in the shoulder joints. Relatively early surgical resection of the HOs can be performed safely in contrary to earlier belief. Afterwards, nonsteroidal anti-inflammatory drugs and/or radiation therapy can be possible treatment modalities to prevent recurrence of HOs. PMID:27583120

    A 40-year-old male paddy field worker was referred for exertional shortness of breath and non-productive cough for 4 years. He had been treated for pulmonary tuberculosis twice. Chest radiograph showed extensive bilateral nodular opacities ("sandstorm-like") in the middle and lower lobe. Pulmonary function tests revealed a restrictive ventilatory defect. High resolution CT showed widespread nodular infiltration with "crazy paving" appearance and interrupted black pleura sign. This was confirmed as pulmonary alveolar microlithiasis (PAM) by trans-bronchial lung biopsy, which showed normal respiratory lining epithelium with dilated alveolar spaces containing many calcific bodies, some of which showed concentric calcification. The possibilities of silicosis (due to exposure to husk) and tuberculosis, both of which can mimic PAM clinically and radiologically, made this case a diagnostic challenge. PMID:21686505

    Antecedentes: el linfoma de Burkitt es una forma agresiva de los linfomas no Hodgkin de células B que ocurre con mayor frecuencia en niños y adultos jóvenes; el linfoma de ovario puede aparecer como lesión primaria o, más comúnmente, como una metástasis. Las lesiones primarias de ovario son manifestaciones raras que corresponden a 0.5% de los linfomas no Hodgkin y 1.5% de los tumores de ovario. Caso clínico: paciente femenina de 31 años de edad, con debilidad generalizada, incapacidad para la marcha, disnea, hiporexia, fiebre, diaforesis, pérdida de 20 kg de peso, abdomen plano, con dolor abdominal; Ca125 610 U/mL. La tomografía computada abdominal mostró un gran tumor de aspecto sólido que afectaba a la cavidad pélvica derecha. Se extirparon los tumores ováricos bilaterales. Desde el punto de vista microscópico ambas lesiones muestran una imagen en "cielo estrellado" compuesta por un patrón de infiltrado monótono de linfocitos mezclada con macrófagos de citoplasma amplio y claro, abundantes mitosis atípicas, zonas de necrosis y hemorragia. La inmunohistoquímica reveló positividad para CDI0 y CD20, negativo con CD3, índice de proliferación Ki67 alto. Se diagnosticó linfoma tipo Burkitt bilateral de ovario. Conclusiones: el linfoma de Burkitt de ovario bilateral es poco frecuente, con variabilidad de presentación; el dolor abdominal y los tumores abdominales son lo más frecuente. El pronóstico a corto plazo de las pacientes es malo, por lo que es necesario conocer esta afección para poder establecer el diagnóstico temprano.

    Recent findings indicate that conscious attention is related to large-scale information integration of various brain regions, including both hemispheres, that enables integration of parallel distributed modalities of processed information. There is also evidence that the level of information transference related to integration or splitting among brain regions, and between hemispheres, establishes a certain level of efficiency of the information processing. The level of information transference also may have modulatory influences on attentional capacity that are closely linked to the emotional arousal and autonomic response related to a stimulus. These findings suggest a hypothesis that changes in conscious attention, specifically during meditation could be reflected in the autonomic activity as the left-right information transference calculated from bilateral electrodermal activity (EDA). With the aim to compare conscious attention during meditation with other attentional states (resting state, Stroop task, and memory task), we performed bilateral EDA measurement in 7 healthy persons during resting state, Stroop task, neurofeedback memory test, and meditation. The results indicate that the information transference (ie, transinformation) is able to distinguish those attentional states, and that the highest level of the transinformation has been found during attentional processing related to meditation, indicating higher level of connectivity between left and right sides. Calculations other than pointwise transinformation (PTI) performed on EDA records, such as mean skin conductance level or laterality index, were not able to distinguish attentional states. The results suggest that PTI may present an interesting method useful for the assessment of information flow, related to neural functioning, that in the case of meditation may reflect typical integrative changes in the autonomic nervous system related to brain functions and focused attentional processing.

    Full Text Available Relata-se o caso de um paciente com dispnéia intensa ao se deitar, em que foram excluídas doenças pulmonares, neuromusculares ou cardíacas, cuja investigação revelou paresia diafragmática bilateral. Um sinal chave para o diagnóstico foi a evidência de respiração paradoxal com o doente em decúbito supino. Havia piora da oxigenação e da capacidade vital forçada com a mudança da posição ortostática para supina. A fluoroscopia ortostática foi normal. A pressão inspiratória máxima estava muito reduzida. A estimulação elétrica transcutânea do diafragma foi normal, e a eletroestimulação do nervo frênico mostrou ausência de resposta, permitindo o diagnóstico de paresia bilateral do diafragma.We report the case of a patient with severe dyspnea upon reclining. Lung disease, neuromuscular disorders and heart disease were ruled out. However, during the course of the investigation, bilateral diaphragmatic paresis was discovered. A key sign leading to the diagnosis was evidence of paradoxical respiration in the dorsal decubitus position. When the patient was moved from the orthostatic position to the dorsal decubitus position, oxygenation and forced vital capacity worsened. The orthostatic fluoroscopy was normal. Maximal inspiratory pressure was severely reduced. The responses to transcutaneous electric stimulation of the diaphragm were normal. However, electric stimulation of the phrenic nerve produced no response, leading to the diagnosis of bilateral diaphragmatic paresis.

  16. Hierarchical bilateral filtering based disparity estimation for view synthesis

    2016-06-01

    In this paper, we introduce a high efficient and practical disparity estimation using hierarchical bilateral filtering for real-time view synthesis. The proposed method is based on hierarchical stereo matching with hardware-efficient bilateral filtering. Hardware-efficient bilateral filtering is different from the exact bilateral filter. The purpose of the method is to design an edge-preserving filter that can be efficiently parallelized on hardware. The proposed hierarchical bilateral filtering based disparity estimation is essentially a coarse-to-fine use of stereo matching with bilateral filtering. It works as follows: firstly, the hierarchical image pyramid are constructed; the multi-scale algorithm then starts by applying a local stereo matching to the downsampled images at the coarsest level of the hierarchy. After the local stereo matching, the estimated disparity map is refined with the bilateral filtering. And then the refined disparity map will be adaptively upsampled to the next finer level. The upsampled disparity map used as a prior of the corresponding local stereo matching at the next level, and filtered and so on. The method we propose is essentially a combination of hierarchical stereo matching and hardware-efficient bilateral filtering. As a result, visual comparison using real-world stereoscopic video clips shows that the method gives better results than one of state-of-art methods in terms of robustness and computation time.

    The present study evaluated the physico-chemical characteristics of muscle biceps femoris and back-fat from purebred Iberian (PBI) pigs and reciprocal crossbred Iberian×Duroc pigs (IB×D pigs: Iberian dams×Duroc sires; D×IB pigs: Duroc dams×Iberian sires). Muscles from PBI pigs contained significantly higher amounts of IMF, heme pigments and iron than those from crossbred pigs. In addition, muscles from PBI pigs were darker (lower L(∗)-values) and redder (higher a(∗)-values) and exhibited a more intense colour (higher chroma value) which was closer to the true red axis (lower hue value) than muscles from crossbred pigs. Back-fat from PBI pigs had significantly higher percentages of monounsaturated fatty acids (MUFA) and significantly smaller percentages of polyunsaturated fatty acids (PUFA) than those from crossbred pigs. Regarding the fatty acid profiles of the muscle lipid fractions, the genetic background particularly affected the composition of the polar lipid (PL) fraction. PL in muscles from PBI pigs contained significantly higher proportions of oleic acid and total MUFA and significantly lower amounts of arachidonic acid, certain long-chain PUFA (ω-6 and ω-3 fatty acids) and total amount of PUFA than PL in muscles from crossbred pigs. The results obtained indicate that tissues from PBI pigs would be more suitable for the production of dry-cured meats than those from cross-bred pigs. The position of the dam or the sire in reciprocal Iberian×Duroc crosses had no clear effects on meat quality.

    Bilateral obturator nerve injury during pelvic surgery is an infrequent cause of lower limb paraparesis. We report the case of a 45-year-old woman with a large uterine leiomyoma who underwent simple total hysterectomy and bilateral salpingectomy. At 24 h after the surgery, the patient noticed loss of muscle strength when adducting both legs. She had no problem with other movements and no sensory or sphincter abnormalities. Neurological examination confirmed that there was loss of strength only in the adductor muscles, with preserved sensory function and reflexes, suggesting bilateral obturator nerve involvement. Pelvic MRI showed a small postsurgical haematoma in the Douglas recess, but far from the obturator nerves. 2 weeks later, electromyography showed positive sharp waves and low motor unit recruitment in the adductor magnus muscles, confirming acute, bilateral obturator nerve neuropathy. The few cases of bilateral obturator neuropathy that have been reported were mostly related to abdominopelvic interventions. PMID:26689250

    2016-06-01

    Bilateral clavicle fractures are uncommonly reported in the literature with the incidence being less than 0.5% of all the clavicle fractures. Bilateral clavicle fractures are caused either by high-energy transfer of compression forces across both shoulder girdles or by a direct trauma to one clavicle followed by that to the other clavicle. These fractures could be missed due to their association with more severe chest injuries or a more symptomatically displaced fracture on one side or due to inadequate chest radiographs. We report three cases of traumatic bilateral clavicle fractures with three modes of injuries in different age groups. All the fractures were treated conservatively with good functional outcomes without any sequelae. Bilateral clavicle fractures should be actively sought by every trauma team with proper clinical examination and chest radiographs including both shoulder joints in high-energy trauma cases or with bilateral shoulder compression injuries.

    The aim of this article is to report the MRI features of bilateral parotid haemangiomas of infancy and highlight the diagnostic and prognostic value of MRI especially with regard to those lesions that may cause respiratory compromise. Retrospective review of MRI scans in six infants with bilateral parotid haemangiomas. The bilateral haemangiomas were symmetrical in all but one patient. On T1-weighted images the masses were isointense to muscle and on T2 they were hyperintense with numerous small vessels giving a septated appearance. There was vivid enhancement with gadolinium in all cases. In three patients, deep bilateral extensions were demonstrated involving the parapharyngeal spaces resulting in respiratory compromise which required tracheostomy. Bilateral parotid haemangiomas are rare, but when present may have deep extensions, which can result in respiratory compromise requiring tracheostomy. (orig.)

    Bilateral periventricular nodular heterotopia is a neuronal migration disorder characterized by gray matter cellular rests in the periventricular regions. Megalencephaly has not been reported in children with bilateral periventricular nodular heterotopia. No other disorder with a similar phenotype has been reported. Here we report the case of a 5-year-old Japanese boy with bilateral periventricular nodular heterotopia and megalencephaly. Relative macrocephaly was evident at birth, and bilateral periventricular nodular heterotopia and megalencephaly were noted on magnetic resonance imaging (MRI). However, no hydrocephalus or indication of cerebral cortical dysplasia was seen. A mild intellectual disability was present, but the patient had no history of seizures. Genetic analysis revealed no mutation on the capillary sequences for FLNA, and no pathogenic abnormalities were evident on array comparative genomic hybridization. This case could represent a new disease entity: bilateral periventricular nodular heterotopia with megalencephaly. PMID:23439715

    Full Text Available Background. The incidence of tubal ectopic gestation caused by schistosomiasis induced tubal pathology is undocumented in this environment, which may be due to rarity of this pathology. Bilateral tubal gestation is common in patients that have undergone in vitro fertilization. We report a hitherto undocumented case of spontaneous bilateral ectopic gestation following tubal schistosomiasis. Case Report. Mrs. OB was a 32-year-old G4P3+0 (3 alive woman who complained of abdominal pain and bleeding per vaginam of 4 and 2 days’ duration respectively following 8 weeks of amenorrhea. A clinical impression of ruptured ectopic gestation was confirmed by ultrasound scanning. She had bilateral salpingectomy with histology of specimens showing bilateral ectopic gestation with Schistosoma haematobium induced salpingitis (findings of Schistosoma haematobium ova noted on slide. Conclusion. Schistosoma induced salpingitis is a rare but possible cause of bilateral tubal gestation.

  5. Comparative gait initiation kinematics between simulated unilateral and bilateral ankle hypomobility: Does bilateral constraint improve speed performance?

    Improvement of motor performance in unilateral upper limb motor disability has been shown when utilizing inter-limb coupling strategies during physical rehabilitation. This suggests that 'default' bilateral central motor commands are facilitated. Here, we tested whether this bilateral motor control principle may be generalized to the lower limbs during gait initiation, which involves alternate bilateral actions. Disability was simulated by strapping to produce ankle hypomobility. Healthy adult subjects initiated gait at a self-paced speed with no ankle constraint (control), or with the stance, swing or bilateral ankles strapped. The duration of the anticipatory postural adjustments lengthened and the center of mass instantaneous progression velocity at foot-off decreased when the ankle was strapped. During the step execution phase, progression velocity at foot-contact was higher when both ankles were strapped compared to unilateral strapping of the stance ankle. These findings suggest that bilateral central motor commands are favored during walking tasks. Indeed, unilateral constraint of the stance ankle should compel the central nervous system to adapt specific commands to the constraint and normal sides whereas the 'default' bilateral motor commands would be utilized when both ankles are strapped leading to better kinematics performance. Bilateral in-phase upper limb coordination and bilateral alternating lower limb locomotor movements may share similar control mechanisms. PMID:26197055

Methods 109 patients with polyneuropathy were studied. The routine nerve conduction study was done and standard EMG was recorded from rectus abdominis muscle, first dorsal interosseous muscle and tibialis anterior muscle. The parameters studied included spontaneous activity fibrillation potentials (fib) and positive sharp waves (psw); duration, amplitude and percentage of polyphasic wave of motor unit action potential (MUAP) and pattern of recruitment. A group of controls and patients with amyotrophic lateral sclerosis (ALS) were studied at the same time. EMG parameters of rectus abdominis muscles were compared among patients with polyneuropathy, patients with ALS and the controls.Results EMG of rectus abdominis muscle in the patients with polyneuropathy showed neurogenic change.The amplitude of motor unit potential in patients with polyneuropathy(451.67±75.01)μV was higher than that of the controls (373.78±56.46)μV (t=2. 01, P < 0. 04) and lower than that of patients with ALS (537.19±159. 04)μV (t=2. 32, P<0.03). Conclusion EMG of rectus abdominis muscle might be used to find the lesion of intercostal nerve in polyneuropathy.

    Full Text Available Background. The challenge in managing patients undergoing renal transplantation is how to achieve optimum levels of anticoagulation to avoid both clotting and postoperative bleeding. We report a rare case of severe postoperative retroperitoneal bleeding including psoas haematomata complicating renal transplantation. Case Report. SM, a 55-year-old female, had a past history of aortic valve replacement, cerebrovascular event, and thoracic aortic aneurysm and was on long-term warfarin that was switched to enoxaparin 60 mg daily a week prior to her living donor transplantation. Postoperatively, she was started on a heparin infusion, but this was complicated by a large retroperitoneal bleed requiring surgical evacuation on the first postoperative day. Four weeks later, she developed features compatible with acute femoral neuropathy and a CT scan revealed bilateral psoas haematomata. Following conservative management, she made steady progress and was discharged home via a community hospital 94 days after transplantation. At her last visit 18 months after transplantation, she had returned to full fitness with excellent transplant function. Conclusion. Patients in established renal failure who require significant anticoagulation are at increased risk of bleeding that may involve prolonged hospitalisation and more protracted recovery and patients should be carefully counselled about this.

    Full Text Available : Mineralisation of all components of stylohyoid complex or chain, a 2nd branchial arch derivative is frequently reported. But bilateral occurrence of continuous bands of ossified tissue involving stylohyoid complex, are less commonly encountered. An adult skull specimen presented abnormally long osseous bands extending from base of skull in place of styloid process. On left side a band of 6.5cm long x1cm wide and 0.3cm in thickness, and on right side an irregularly rounded elongated structure of 7.5cm length were noticed. Lower end of the left process was fused to hyoid bone. Either abnormally long styloid process or this type of ossified stylohyoid complex may be a causative factor for severe pharyngeal pain, dysphagia, may be a cause for occasional swelling in submandibular region or may be associated with Eagle syndrome. Due to its close proximity to tonsillar bed, if elongated it may be felt during tonsillectomy in tonsillar fossa. In this backdrop reports of this type may be of interest to clinicians.

    Full Text Available We herein report a case of synchronous bilateral solid papillary carcinoma of the breast. A 73-year-old female had a mass that was detected in the right breast on mammography. An ultrasound examination revealed one intracystic tumor in the right breast and two tumors in the left breast. A fine-needle aspiration biopsy of these three tumors was performed, which revealed a diagnosis of malignancy. A magnetic resonance imaging examination of the breasts showed diffuse small nodules surrounding these tumors bilaterally. Bilateral partial mastectomy and a sentinel lymph node biopsy were performed. Lymph node metastasis was detected in the right axilla, and additional lymph node dissection was performed. The pathological diagnosis was synchronous bilateral breast cancer, invasive ductal carcinoma NOS of the right breast, mucinous carcinomas of the left breast, and bilateral SPCs. A wide range of surgical margins were positive for SPCs, and additional bilateral total mastectomy was then performed. To the best of our knowledge, little is known about synchronous bilateral SPCs. Our case indicates that some SPCs can be widely scattered and make up a variety of invasive carcinomas. It is difficult to make a correct preoperative evaluation in such cases.

    2012-07-01

    Full Text Available Maisonneuve fractures result from a disruption of the medial ankle structures and a proximal fibular fracture. Patient complaints can be misleading and there is a significant rate of delayed diagnosed injuries. We present a case of bilateral Maisonneuve fractures after a fall due to a syncopal collapse. A precise clinical examination led to this rare diagnosis. The injuries were treated with syndesmotic screw fixation, removal of hardware followed after 6 weeks. The patient was asymptomatic at threemonths follow up. Patients with bilateral injuries undergoing standard surgical treatment can gain full recovery, but high suspicion in clinical examination is needed to detect this uncommon bilateral injury.

    Full Text Available In this case report, we present occurrence of bilateral angle closure glaucoma in a 9-year-old girl with geleophysic dysplasia. Bilateral YAG laser iridotomy was applied, but intraocular pressure (IOP remained at high levels, necessitating bilateral trabeculectomy with mitomycin C. On her follow-up examinations for 3 years, IOP remained in the mid-20s with no need for further intervention or antiglaucoma medication. There are few reports describing the ocular findings of geleophysic dysplasia in literature. To our knowledge, this is the first case report describing an application of glaucoma surgery and its results at geleophysic dysplasia.

    Full Text Available The aim of this work is the integration of a virtual environment containing a deformable object, manipulated by an open kinematical chain virtual slave robot, to a bilateral teleoperation scheme based on a real haptic device. The virtual environment of this hybrid bilateral teleoperation system combines collision detection algorithms, dynamical, kinematical and geometrical models with a position–position and/or force–position bilateral control algorithm, to produce on the operator side the reflected forces corresponding to the virtual mechanical interactions, through a haptic device. Contact teleoperation task over the virtual environment with a flexible object is implemented and analysed.

    International Nuclear Information System (INIS)

    Among the publications of CDC Climat Research, 'Climate Briefs' presents, in a few pages, hot topics in climate change policy. This issue addresses the following points: In order to achieve its long-term emission reduction target following the Fukushima incident, Japan would rely more heavily on international offsetting activities. Concurrent to vigorous proposals to reform the CDM, Japan is also promoting an offset crediting scheme through bilateral agreements with developing countries as a post-2012 market mechanism. Despite potential benefits, issues relating to the accounting rules, environmental integrity and implications to carbon markets warrant further consideration prior to international recognition

    The aim of this study was to investigate the detailed configuration of periocular elastic fibers. Semiserial paraffin sections were made using 40 whole orbital contents from 27 elderly cadavers and stained by the aldehyde-fuchsin method. Periocular tissues were classified into three types according to directions of the elastic fibers, i.e., tissues containing anteroposteriorly running elastic fibers, those with mediolateral fibers, and those with meshwork of fibers. Anteroposterior elastic fiber-dominant tissue was seen in the upper eyelid and newly defined pulley plate for the medial and lateral recti (MR, LR). Mediolateral fibers were predominant in the central part of the inferior rectus pulley. In the pulley plates for the MR and LR, anteroposteriorly running fibers encased the striated muscle. Tenon's capsule and the epimysium of the recti were mediolateral fiber-dominant. However, at the entrance of the muscle terminal where Tenon's capsule reflects and continues to the epimysium, composite elastic fibers provided a meshwork-like skeleton. The elastic mesh was also seen around the lacrimal canaliculi. The pulley for the recti seemed to be composed of two parts--a connective tissue plate encasing the recti and specialized Tenon's capsule at an entrance or porta of the muscle. For both parts, elastic fibers were major functional components. The anteroposterior elastic fibers in the MR and LR pulley plates, especially, seemed to receive anteroposteriorly directed stress and tension from these striated muscles. The elastic interfaces seemed to prevent any concentration of stress that would interfere with periocular striated muscle functions, including hypothetical active pulleys.

    Over 40,000 postmastectomy breast reconstructions are performed annually. In this study, we investigated the psychosocial, functional, and cosmetic effects of transverse rectus abdominis musculocutaneous (TRAM) flap versus breast implant reconstruction. Thirty-three women who had undergone postmastectomy breast reconstruction were contacted by telephone and agreed to participate in the study. Twenty-two women completed the self-assessment questionnaires regarding their quality of life, psychological symptoms, functional status, body image, and global satisfaction. The TRAM and implant groups contained 8 and 14 patients, respectively. The groups were well matched for age, employment status, marital status, race, religion, and severity of medical and surgical illnesses. The average follow-up was 36 months. Statistical analysis of the responses revealed that women who had undergone TRAM flap reconstruction were more satisfied with how their reconstructed breast felt to the touch (p = .01), and there was a trend toward greater satisfaction with the appearance of their reconstructed breast (p = .08). However, these same patients identified more difficulties as far as functioning at work or school, performing vigorous physical activities, participating in community or religious activities, visiting with relatives, and interacting with male friends (p < .04). There were no statistically significant differences in body image or overall satisfaction. In this small cohort study, both the TRAM flap group and the implant group were satisfied with the results of their breast reconstruction, but the TRAM flap group was more satisfied with how their breast felt and tended to be more satisfied with the cosmetic result. The TRAM flap group reported greater psychological, social, and physical impairments as a result of their reconstruction. PMID:8579262

O cão morreu por peritonite séptica aguda, decorrente de ulceração e perfuração intestinal por corpo estranho linear. O neoplasma foi achado incidentalmente durante a necropsia. Macroscopicamente, as adrenais estavam redondas e com volume e aumentados. Ao corte elas eram friáveis, vermelho-amarronzadas, intercaladas por áreas branco-amareladas levemente proeminentes. Histologicamente, extensas áreas do parênquima continham adipócitos bem diferenciados, células hematopoéticas e macrófagos com hemossiderina, achados característicos de mielolipoma adrenal.A case of bilateral adrenal myelolipoma in a 13-year-old female Poodle is reported. Acute septic peritonitis due to intestinal ulceration and perforation caused by a linear foreign body was the cause of death. The adrenal neoplasm was an incidental necropsy finding. The adrenal glands were grossly rounded, enlarged and friable, and had red-brownish parenchyma interwoven by slightly prominent white-yellowish foci. Histologically, the findings of differentiated adipocytes in large areas of the parenchyma, in association to hematopoietic cells and macrophages with hemosiderin were consistent with the diagnosis of adrenal myelolipoma.

    2012-01-01

    Full Text Available Bilateral sixth nerve paresis following closed head injury, though rare, is a known entity. However, delayed-onset post-traumatic bilateral abducens paresis is extremely rare. We present two cases. The first patient had onset of bilateral abducens paresis 2 weeks after closed head injury and the second patient after 3 days. The cause in the former was detected to be chronic subdural hematoma and in the latter is speculated to be edema/ischemia due to injury to soft tissue structures housing these nerves. The delayed onset of bilateral abducens paresis following head injury may vary according to the cause. There may be another mechanism of injury apart from direct trauma. Though rare, it needs to be evaluated and may have a treatable cause like elevated intracranial pressure.

  7. Bilateral Teleoperation in Cartesian Space with Time-Varying Delay

    Directory of Open Access Journals (Sweden)

    Zhang Chen

    2012-10-01

    Full Text Available The bilateral control of a teleoperator in Cartesian space with time‐varying delay is studied in this paper. Compared with the traditional joint‐space teleoperation mode, bilateral control in Cartesian space has advantages when dealing with the kinematically dissimilar (KDS teleoperation systems. A Cartesian space‐based PD‐like bilateral controller with dissipation factors is designed. Considering the fact that attitude errors derived by rotation matrix cannot be directly used for PD control, a quaternion‐based approach is adopted to calculate the attitude errors in Cartesian space. In order to overcome the instability brought about by communication delay, local damping components are employed at both ends of the teleoperator system. The variation of time delay may generate extra energy and influence the stability of the system, thus dissipation factors are introduced into the controller. The stability of the proposed bilateral controller is proved and the simulations show the effectiveness of the approach.

    Limbal stem cell deficiency (LSCD) is now established as a distinct entity with a spectrum of clinical manifestations. Bilateral LSCD presents a unique set of challenges to the clinician dealing with ocular surface disease, due to the underlying causes, clinical presentation, and adnexal status, as well as lack of a source of autologous limbal stem cells. Various surgical modalities have been described to achieve visual rehabilitation in patients with bilateral LSCD. These can primarily be divided into cell-based therapies and implantation of keratoprostheses. In this review, the surgical options for management of bilateral LSCD, including autologous and allogeneic cell-based therapies and different types of keratoprostheses are described and classified. The indications, prerequisites, technique, results and complications of each modality are discussed. Based on the status of the ocular surface, an algorithm for choosing appropriate surgical management for vision restoration in bilateral LSCD has been proposed. PMID:27151421

    Full Text Available Introduction: Bilateral shoulder dislocation are most commonly posterior type. These are most commonly due to seizure disorder and electrocution. Anterior shoulder dislocations occurring bilaterally without any predisposing factors are very rare. These types of injuries are due to trauma with a unique mechanism of injury. To best of our knowledge there are only few cases of similar kind are reported in literature. We hereby report a interesting case of posttraumatic, bilateral anterior dislocation of shoulder without associated fracture in a 45 old women without any predisposing pathoanatomy.Case Report: A 45-year-old women presented to casualty with sudden onset of pain and restriction of movement in both shoulders fallowing trauma. Immediately post trauma she had severe pain and restriction of both shoulders. On examination arms were abducted and externally rotated. Bilateral shoulder movements were painful and restricted . There was loss of round contour of shoulder with increased vertical diameter of axilla anteriorly. Radiological examination revealed bilateral anterior dislocation of the shoulders without any associated fractures. Closed reduction done by Milch technique after intraraticular lignocaine injection. MRI of bilateral shoulder showed no pathological lesion. Both shoulders were immobilized with a shoulder immobilizer for three weeks.Conclusion: Most of the bilateral shoulder dislocations are posterior type seen in seizure disorders. Bilateral traumatic anterior shoulder dislocations are rare and are seen as a result of unique mechanism of injury. In our case patient had a fall on her elbows causing forced extension. If diagnosed and treated promptly completely normal function of the shoulders can be restored.

    Bilateral Cochlear implants (CIs) improved speech intelligibility, speech perception in background noise, and sound localization in quiet and noisy situations. However, it is unclear whether these advantages essentially result in binaural integration of acoustic stimuli from each ear. In this study, we investigated the effectiveness of binaural integration by bilateral CIs placement using binaural hearing tests and subjective auditory perceptual assessment. A 61-year-old bilateral CIs subject underwent the following four tests:the Japanese Hearing in Noise Test (HINT-J), the dichotic listening test (DLT), the Rapidly Alternating Speech Perception (RASP) test, and subjective auditory perceptual assessment. The HINT-J score was significantly higher for bilateral CIs than for a unilateral CI. However, DLT and the RASP test revealed contradictory results. Subjective auditory perceptual assessment revealed active and bright impressions for bilateral hearing, which were also noisy and strong compared with those for unilateral hearing. The results of this study revealed that bilateral CIs improved speech perception in background noise and an improved auditory impression, although the bilateral integration abilities were not improved. This was probably because the patient was required to combine information from the two ears into a single perception in DLT and the RASP test. More longitudinal data should be collected and analyzed in future studies to evaluate the long-term effects of bilateral CIs.

    2016-10-01

    Benefits of bilateral practice both for the non-dominant and for the dominant body side have been shown in several studies. Thereby, most of the studies included movement tasks of the upper extremity or investigated sports games in which the ability of acting bilaterally is an essential basis for success and, thus, a bilateral practice is reasonable anyway. Individual unilaterally performed sports including movement tasks of the lower extremity are rarely investigated. Therefore, the aim of our study was to test if contralateral transfer due to bilateral practice can be found in an unilaterally performed sport including the lower extremity. We trained and tested 61 adolescent athletes in long jump to compare the jumping performance of the dominant leg after a 12-week practice period between two groups: a bilateral practice group that practiced specific long jump exercises with both the dominant and non-dominant leg and an unilateral practice group that practiced specific long jump exercises only with the dominant leg. Results showed a superior effect of bilateral practice compared to unilateral practice regarding the jumping performance of the dominant leg. The performance increase at post-test and retention-test for the dominant limb was significantly higher for the bilateral practice group (pre-to-post: 5.2%, pre-to-retention: 7.4%) compared to the unilateral practice group (pre-to-post: 3.4%, pre-to-retention: 4.5%). Thus, bilateral practice should be established in the early practice programmes of track and field athletes to improve the performance of the dominant take-off leg. PMID:26864045

    Full Text Available Introduction: Anterior dislocation of shoulder is commonest dislocation one encounters in day to day Orthopaedic practice. But bilateral shoulder dislocations are relatively uncommon frequently posterior and secondary to violent muscle contraction. Simultaneous bilateral anterior dislocations of shoulder following trauma is rare occurrence. Case Report: 35 year old male presented to emergency department with history fall by tripping on a stone (fall on outstretched hand. He complained of pain and difficulty in moving both the shoulders. On clinical examination, patient’s both upper limbs were abducted and externally rotated. Bilaterally shoulder contour was lost with flattening. Other classical signs of shoulder dislocation viz, Bryants test, Callway sign, Hamilton’s ruler test were positive. Diagnosis was confirmed on X rays. Both shoulders were reduced in emergency operation theater under general anaesthesia by Kocher’s method and were immobilised in sling. Conclusion: Though bilateral shoulder dislocations are commonly posterior, usually either secondary to convulsions or electric shock, anterior dislocation has to be kept in mind , especially in post traumatic injuries. This bilateral dislocation also presents with practical problems immobilization and day to day care of patients. Keywords: Simultaneous, bilateral, shoulder dislocation, traumatic.

    Full Text Available Introduction Sense of smell is susceptible to various changes, both in physiological and in numerous pathological conditions. Of quantitative disorders of smell, hyposmia and anosmia are quite common, whereas of qualitative disorders parosmia is most frequent. The aim of this paper was to examine impact of bilateral nasal polyposis on olfactory function. Material and methods The research was carried out at the Nose, Ear and Throat Clinic in Novi Sad. It included 80 examinees, 40 (20 male, 20 female with bilateral nasal polyposis, while 40 examinees belonged to the control group (20 male, 20 female without symptoms of nasal polyposes. Fortunato-Niccolini olfactometer was used for this examination. Results and discussion In patients with bilateral nasal polyposis the average perception threshold values for examined odors were 15.50 ccm of odorous air, while in the control group they were 10,20 ccm of odorous air. The average identification threshold values for examined odors in patients with bilateral nasal polyposis were 18.80 ccm of odorous air, while in the control group they were 13.55 ccm of scented air. T-test showed that values of both tresholds were statistically significantly higher (p< 0,01 in patients with bilateral nasal polyposis in relation to the control group. Conclusion Olfactory deficit in patients with bilateral nasal polyposis is explained by difficult or impossible passage of odors into the olfactory region.

    It is generally thought that simultaneous bilateral chest surgery carries a high morbidity. We reviewed the results of simultaneous (under one anesthesia) vs staged bilateral video-assisted thoracoscopic surgery (VATS) from a single institution over a 35-month period. From September 1992 to July 1995, we performed simultaneous bilateral VATS on 37 patients (31 males, six females, age ranging from 15 to 55 years) with spontaneous pneumothorax (20) for bleb resections and pleurodesis; thoracodorsal sympathectomy (12) for palmar hyperhidrosis and vasospastic disease; and metastatic sarcomas (five) for wedge lung resections. During the same period, nine patients with metachronous bilateral spontaneous pneumothorax had staged procedures, as did two with digital ischemic ulcers for sympathectomy and three with metastatic pulmonary osteosarcomas for resection. Mean postoperative hospital stays in days for the simultaneous groups were 3.3 for spontaneous pneumothorax, 2.1 for sympathectomy, and 1.5 for wedge resection, compared to 2.9, 2.5, and 2.2 for the staged groups, respectively (p > 0.05 by Mann-Whitney U tests). Likewise, pain assessment by visual analogue scale as well as analgesic requirement showed no significant difference between the simultaneous and the staged groups. We conclude that simultaneous VATS is not associated with increased morbidity or prolonged hospital stay compared to the staged counterparts and provides an attractive alternative to the median sternotomy, bilateral posterolateral thoracotomy, or transternal (clam-shell) thoracotomy for selected cases of simultaneous bilateral lung surgery.

    Levent Tok

    2014-12-01

    Full Text Available Purpose: The purpose of this study was to document clinical findings and management of a patient with bilateral globe luxation and optic nerve transection. Materials and Methods: A 25-year-old female patient was admitted to the emergency department with bilateral traumatic globe luxation following a motor vehicle accident. Results: Visual acuity testing showed no light perception. The right pupil was dilated and bilaterally did not react to light. The globes were bilaterally intact. A computed tomography scan revealed Le Fort type II fractures, bilateral optic nerve transection and disruption of all extraocular muscles. The globes of the patient were bilaterally reduced into the orbit. However, the patient developed phthisis bulbi in the right eye at month 3. Conclusion: Globe luxation presents a dramatic clinical picture, and may lead to the development of severe complications due to the concomitance of complete optic nerve dissection and multiple traumas. Even if the luxated globe is repositioned into the orbit, there is still an increased risk of the development of phthisis due to ischemia.

    Emphysematous pyelonephritis (EPN) is a serious infectious disease that occurs more frequently in diabetic patients. Radiological studies are indispensable for distinguishing between the two types since each is associated with a markedly different prognosis. We present a case of bilateral EPN diagnosed as type I on the basis of computed tomography findings, differentiating it from type II EPN, taking into account the prognostic value of this distinction. Type I EPN is characterized by the destruction of the renal parenchyma, a mottled or linear gas pattern and the absence of renal and perirenal fluid collection. Type II EPN is characterized by a loculated or bubbly gas pattern, the existence of fluid collection and less marked renal destruction. Type I is more aggressive and is associated with high rate of mortality. (Author) 7 refs.

Material/Methods From 2009 to 2014, 145 patients were recruited. Among them, 70 underwent SBCAS, and other 75 patients underwent SAMM and served as controls. The immediate postprocedural complications and postprocedural neurological evaluation, as well as restenosis at 6-month and 1-year follow-ups in the SBCAS group are reported. Additionally, baseline risk factors for ischemic stroke, adverse effects of drugs, and outcomes at 30-day, 6-month, and 1-year follow-ups were compared between the 2 groups. Results Our data did not reveal significant differences between the 2 groups in baseline risk factors for ischemic stroke. In the SBCAS group, both HPS (5.7%) and HD (40%) occurred, but they were not very severe, and no patients had postprocedural neurological deficit. Moreover, restenosis only occurred in 3 patients at 3 stent placement sites (4.3%) at 1-year follow-up. Adverse effects of drugs did not occur in SBCAS group, but adverse effects of Bayer aspirin and Lipitor occurred in 4 patients (5.4%) and 18 patients (24.3%), respectively, at 6-month follow-up in the control group. Furthermore, there were significant differences in outcomes between the 2 groups at 30-day, 6-month, and 1-year follow-ups, in that NIHSS, CS ratio, and incidence of endpoint events, as well as 1-year cumulative probability of endpoint events, were all lower in the SBCAS group than in the control group (p<0.05). Conclusions Compared to SAMM, we found that SBCAS was more effective and safer for symptomatic bilateral high-grade CS. PMID:27542158

    Purpose: This retrospective study examined the feasibility and efficacy of bilateral lung radiofrequency ablation (RFA) performed in a single session. Methods: From 2002-2009, patients with bilateral lung metastases were treated by RFA, where possible in a single session under general anesthesia with CT guidance. The second lung was punctured only if no complications occurred after treatment of the first lung. Five lung metastases maximum per patient were treated by RFA and prospectively followed. The primary endpoint was the evaluation of acute and delayed complications. Secondary endpoints were calculation of hospitalization duration, local efficacy, median survival, and median time to tumor progression. Local efficacy was evaluated on CT or positron emission tomography (PET) CT. Results: Sixty-seven patients were treated for bilateral lung metastases with RFA (mean age, 62 years). Single-session treatment was not possible in 40 due to severe pneumothoraces (n = 24), bilateral pleural contact (n = 14), and operational exclusions (n = 2). Twenty-seven (41%) received single-session RFA of lesions in both lungs for 66 metastases overall. Fourteen unilateral and four bilateral pneumothoraces occurred (18 overall, 66.7%). Unilateral (n = 13) and bilateral (n = 2) chest tube drainage was required. Median hospitalization was 3 (range, 2-8) days. Median survival was 26 months (95% confidence interval (CI), 19-33). Four recurrences on RFA sites were observed (4 patients). Median time to tumor progression was 9.5 months (95% CI, 4.2-23.5). Conclusions: Although performing single-session bilateral lung RFA is not always possible due to pneumothoraces after RFA of first lung, when it is performed, this technique is safe and effective.

    Background Bilateral adrenal masses may have aetiologies like hyperplasia and infiltrative lesions, besides tumours. Hyperplastic and infiltrative lesions may have coexisting hypocortisolism. Bilateral tumours are likely to have hereditary/syndromic associations. The data on clinical profile of bilateral adrenal masses are limited. Aims To analyse clinical, biochemical and radiological features, and management outcomes in patients with bilateral adrenal masses. Methods Retrospective analysis of 70 patients with bilateral adrenal masses presenting to a single tertiary care endocrine centre from western India (2002–2015). Results The most common aetiology was pheochromocytoma (40%), followed by tuberculosis (27.1%), primary adrenal lymphoma (PAL) (10%), metastases (5.7%), non-functioning adenomas (4.3%), primary bilateral macronodular adrenal hyperplasia (4.3%), and others (8.6%). Age at presentation was less in patients with pheochromocytoma (33 years) and tuberculosis (41 years) compared with PAL (48 years) and metastases (61 years) (PAI) (95%). The presenting symptoms for PAL were AI (57%) and abdominal pain (43%), whereas all cases of metastasis had abdominal pain. Mean size of adrenal masses was the largest in lymphoma (5.5cm) followed by pheochromocytoma (4.8cm), metastasis (4cm) and tuberculosis (2.1cm) (P<0.001). Biochemically, most patients with pheochromocytoma (92.8%) had catecholamine excess. Hypocortisolism was common in tuberculosis (100%) and PAL (71.4%) and absent with metastases (P<0.001). Conclusion In evaluation of bilateral adrenal masses, age at presentation, presenting symptoms, lesion size, and biochemical features are helpful in delineating varied underlying aetiologies.

  16. US findings of bilateral primary breast cancer: Retrospective study

    International Nuclear Information System (INIS)

    Background: For women with breast cancer, the contralateral breast is at high risk. The bilateral cancers may be synchronous or metachronous. If the bilateral breast cancers have similar ultrasonography (US) appearances, the US findings of the first breast cancer (index cancer) might lead to early detection of the contralateral cancer. The purpose of this study was to identify the US characteristics of bilateral breast cancer and to determine whether bilateral breast cancers have similar US appearances and whether the US findings for one breast cancer might be predictive of the contralateral breast cancer. Methods: We retrospectively reviewed the US manifestations of 58 patients with surgically proven bilateral primary breast cancer and compared the contralateral cancer with the index cancer by evaluation the margin, shape, inside echoes, posterior attenuation, calcification and color flow signals of 58 lesion pairs to investigate whether the bilateral breast cancers have similar US appearances. Results: Bilateral primary breast cancers were more located in upper outer quadrant, frequently spiculation, taller than wide shape, with irregular margin, heterogeneous internal echo and acoustic shadowing, containing microcalcification and abundant color flow signals. The most common US appearances were taller than wide shape (75.0%, 87/116), irregular margins (79.3%, 92/116) and heterogeneous internal echo (86.2%, 100/116). Of the total 58 lesion pairs, 18 (31.0%) pairs had similar US characteristics, whereas 40 (69.0%) pairs had different US characteristics. Conclusions: US signs of the index cancer do not indicate the most likely appearance of the second cancer in the contralateral breast. Evaluation of the contralateral cancer should be performed without regard for the US findings for the index cancer

    Full Text Available Abstract Background Herpes zoster oticus accounts for about 10% cases of facial palsy, which is usually unilateral and complete and full recovery occurs in only about 20% of untreated patients. Bilateral herpes zoster oticus can sometime occur in immunocompromised patients, though incidence is very rare. Case presentation Diabetic male, 57 year old presented to us with bilateral facial palsy due to herpes zoster oticus. Patient was having bilateral mild to moderate sensorineural hearing loss. Patient was treated with appropriate metabolic control, anti-inflammatory drugs and intravenous acyclovir. Due to uncontrolled diabetes, glucocorticoids were not used in this patient. Significant improvement in hearing status and facial nerve functions were seen in this patient. Conclusions Herpes zoster causes severe infections in diabetic patients and can be a cause of bilateral facial palsy and bilateral Ramsay Hunt syndrome. Herpes zoster in diabetic patients should be treated with appropriate metabolic control, NSAIDS and intravenous acyclovir, which we feel should be started at the earliest. Glucocorticoids should be avoided in diabetic patients.

    Little is known about the use of breast MRI as a diagnostic or surveillance tool in patients after bilateral mastectomy. The objective of this study was to evaluate breast MRI after bilateral mastectomy. Participants consisted of 48 women with prior bilateral mastectomy who underwent breast MRI between 2003 and 2009. Seventy-nine breast MRIs were obtained. The median time between mastectomy and first MRI was 36 months. MRI was ordered most often by a medical oncologist (71%). Median age at bilateral mastectomy was 49 years (range, 33 to 72 years). Reasons for obtaining MRI included surveillance in 60 (76%), mass in eight (10%), lymph nodes in four (5%), pain in three (4%), and abscess in one (1%). Overall, 68 (86%) MRIs showed benign imaging findings only. Within the surveillance group, six patients had MRIs with findings that changed management; four patients had some residual breast tissue, and two patients had findings outside the breast that were better evaluated by CT or bone scan and were ultimately benign. MRI confirmed locoregional recurrence in two patients with highly suspicious physical findings. Overall, postmastectomy breast MRI had limited use, finding no unsuspected recurrences within our study group. Although MRI can be helpful to establish the presence of residual breast tissue after bilateral mastectomy, subsequent routine screening breast MRI should be questioned if no residual breast tissue is identified.

    A seven-year-old, 41 kg, intact, cross breed dog, was presented with a history of bilateral hind limb lameness after falling from a height of 1 m. Clinical and radiographic findings were consistent with bilateral patellar tendon rupture. Surgical repair was performed bilaterally. The tendons were sutured primarily, and an internal splint of nylon leader was added. Good apposition of the severed tendon ends had been achieved intraoperatively; however, post operative radiographs showed supra-trochlear displacement of both patellae. The casts used to immobilize the stifle joints slipped distally and three days post operatively the tendon repair had broken down, bilaterally. Revision surgery was undertaken and the tendons were re-sutured. Nylon leader was placed through holes that had been drilled in the patellae and tibiae. The stifle joints were immobilized with type I external skeletal fixators (ESFs). Both freeform polymethylmethacrylate (PMMA) connecting bars were found to be broken at the level of the stifle joints two days later, without any disruption of the primary tendon repair. Each connecting bar was replaced with two connecting bars of PMMA reinforced with 3 mm steel wire. The dog was fully weight-bearing with a reduced range of motion in flexion immediately after removal of the ESFs at six weeks and was still sound 18 months post-operatively. Primary tendon repair in combination with adequate immobilization allowed for an excellent outcome in a complicated bilateral pathology. PMID:18545725

    Full Text Available Two female patients with histories of cancer who showed cryptogenic organizing pneumonia (COP complications and bilateral anterior uveitis with hypopyon were examined. Both patients had suffered from COP and received intermitted systemic corticosteroid administration (SCA. The first patient, a 65-year-old woman with a history of breast cancer, showed bilateral uveitis with hypopyon. The topical corticosteroid treatment was ineffective. After SCA for the treatment of COP was started, the hypopyon gradually dissipated. Upon termination of SCA, uveitis relapses were controlled by renewed SCA. The other patient, a 69-year-old woman with a history of ovarian cancer, showed bilateral anterior uveitis with hypopyon. Her intraocular outcome did not improve by the topical corticosteroid administration, but SCA that was applied to treat COP led to remission of uveitis. Imaging examinations, biochemical analysis, symptoms or HLA-B27 antigen screenings in either patient did not explain the development of uveitis. Bilateral anterior uveitis is commonly related to autoimmune disease or systemic syndrome. We report two cases with COP that developed bilateral anterior uveitis with hypopyon resistant to topical administration but responsive to systemic administration of corticosteroid. These findings suggest that COP can be associated with the etiology of anterior uveitis.

    A persistent trigeminal artery (PTA) is the most common anastomosis between the carotid and vertebrobasilar system. A PTA variant (PTAV) is a rare anomaly in which the cerebellar artery arises from the internal carotid artery (ICA) without connection with the basilar artery (BA). I present what I believe is the first report of bilateral PTAVs diagnosed using magnetic resonance (MR) angiography and briefly discuss the embryology of this rare anomaly. An 81-year-old woman with small infarctions underwent cerebral MR imaging and MR angiography with a 1.5-tesla imager for the evaluation of brain lesions. An MR angiography was obtained using the standard noncontrast three-dimensional time-of-flight technique. The MR angiographic demonstration of bilateral anterior inferior cerebellar arteries arising from the precavernous segment of the ICA without anastomosis to the BA indicated bilateral PTAVs. This is the first report of bilateral PTAVs diagnosed by MR angiography. The literature review indicates that an estimated prevalence of bilateral PTAVs is about 0.0012%. PMID:21544587

    This case highlights the diagnostic challenges in patients presenting with bilateral sudden sensorinueral hearing loss (SNHL). The aetiology of bilateral sudden SNHL may span several medical disciplines. Therefore, clinicians should be mindful of such presentations, and consider aetiologies beyond otological and neurological causes. We present a case of a previously healthy 51-year-old woman who presented with coryzal symptoms and sudden audiovestibular failure. Examination revealed fever, tachycardia, bilateral profound hearing loss and nystagmus. Following investigations, an initial working diagnosis of vasculitis was made. Later, blood cultures revealed methicillin-sensitive Staphylococcus aureus (MSSA) and a transoesophageal echocardiogram confirmed endocarditis. The patient made a good recovery, but the hearing loss was permanent and managed with a cochlear implant.

    Based on the basic trade gravity model and Xinjiang's practical situation, new explanatory variables (GDP,GDPpc and SCO) are introduced to build an extended trade gravity model fitting for Xinjiang's bilateral trade. Fromthe empirical analysis of this model, it is proposed that those three variables affect the Xinjiang's bilateral trade posi-tively. Whereas, geographic distance is found to be a significant factor influencing Xinjiang's bilateral trade negatively.Then, by the extended trade gravity model, this article analyzes the present trade situation between Xinjiang and itsmain trade partners quantitatively in 2004. The results indicate that Xinjiang cooperates with its most trade partnerssuccessfully in terms of present economic scale and developing revel. Xinjiang has established successfully trade part-nership with Central Asia, Central Europe and Eastern Europe, Western Europe, East Asia and South Asia. However,the foreign trade development with West Asia is much slower. Finally, some suggestions on developing Xinjiang's for-eign trade are put forward.

    Full Text Available A rare case of bilateral fat necrosis of the breast is reported. The patient was a 50-year-old unmarried woman having no history of trauma, disease or surgery of the breast. In the bilateral breasts, ill-defined, firm masses with skin retraction were noted. Bilateral breast cancer was diagnosed clinically. However, both lesions showed histologically chronic granulomatous inflammation with foci of fatty necrosis, infiltration of lymphocytes, plasma cells, lipid containing foamy cells, foreign body giant cells engurfing choresterol-crystals, and calcification. "Paraffinoma" was thus suspected, but there was no history of cosmetic mammoplasty and histochemical studies failed to demonstrate saturated lipid indicating paraffin or other mineral oils

    Full Text Available A 72-year-old man presented with constipation. He was hypertensive and suffered from chronic constipation. On arrival, the patient was fully conscious, and his vital signs were stable. He requested an enema because this treatment had proved effective in the past. On physical examination, a hard palpable mass was detected in the lower abdomen. Computed tomography was performed with contrast media. It revealed an abdominal aortic aneurysm (AAA and bilateral internal iliac artery aneurysms (IIAAs; the latter obstructing the sigmoid colon. We believe that this obstruction was the cause of constipation. The patient underwent Y-graft replacement for the treatment of the AAA and bilateral IIAAs. The surgery was successful, and constipation has not recurred since. As constipation is the most common digestive disorder in the general population, all physicians should be aware that chronic constipation can be caused by bilateral IIAAs.

    Full Text Available The international trade for wide world countries in the means more growth, more jobs and access on more products at competitive prices. The European Union is a major economy and an important trading partner for many countries and regions in the world. To stimulate growth and to create jobs in the Union, this economy has concluded multilateral trade agreement (under the World Trade Organisation and a number of bilateral (preferential trade agreements. The aim of this paper is to present an example of fully elimination of tariffs and tariff lines under a bilateral trade agreement. In this case, we have analysed Comprehensive Economic and Trade Agreement (CETA negotiated by the European Union and Canada. For both sides of Atlantic, the CETA is supposed to bring the solution for today's issues concerning the important trading aspects and, also, to facilitate the EU-Canada bilateral trade by creating competition.

    Historically, the study of speech processing has emphasized a strong link between auditory perceptual input and motor production output. A kind of 'parity' is essential, as both perception- and production-based representations must form a unified interface to facilitate access to higher-order language processes such as syntax and semantics, believed to be computed in the dominant, typically left hemisphere. Although various theories have been proposed to unite perception and production, the underlying neural mechanisms are unclear. Early models of speech and language processing proposed that perceptual processing occurred in the left posterior superior temporal gyrus (Wernicke's area) and motor production processes occurred in the left inferior frontal gyrus (Broca's area). Sensory activity was proposed to link to production activity through connecting fibre tracts, forming the left lateralized speech sensory-motor system. Although recent evidence indicates that speech perception occurs bilaterally, prevailing models maintain that the speech sensory-motor system is left lateralized and facilitates the transformation from sensory-based auditory representations to motor-based production representations. However, evidence for the lateralized computation of sensory-motor speech transformations is indirect and primarily comes from stroke patients that have speech repetition deficits (conduction aphasia) and studies using covert speech and haemodynamic functional imaging. Whether the speech sensory-motor system is lateralized, like higher-order language processes, or bilateral, like speech perception, is controversial. Here we use direct neural recordings in subjects performing sensory-motor tasks involving overt speech production to show that sensory-motor transformations occur bilaterally. We demonstrate that electrodes over bilateral inferior frontal, inferior parietal, superior temporal, premotor and somatosensory cortices exhibit robust sensory-motor neural

    We report on an Italian boy, born to normal and nonconsanguineous parents with a prenatal diagnosis of ventriculomegaly and subependymal glial heterotopias. At birth bilateral macrostomia was diagnosed without other evident facial anomalies. Magnetic resonance imaging (MRI) showed triventricular hydrocephalus and aqueductal stenosis and confirmed the nodules of glial heterotopia. The bilateral macrostomia was surgically corrected with the vermilion square flap method and W-plasty technique and follow up MRI at 6 months showed mild increase of ventricular dilatation without signs of active hydrocephalus. The association between macrostomia and hydrocephalus has been reported only in rare cases of complex malformative syndromes but never with isolated macrostomia.

  13. Bilateral transaction bargaining between independent utilities under incomplete information

    International Nuclear Information System (INIS)

    A new approach to designing bilateral power transaction bargaining models between two independent utilities in a deregulated electricity market is proposed. In the paper it is assumed that each utility (a seller or a buyer) knows its own operating costs but does not know those of its opponent. The bilateral power transaction problem is then considered as non-cooperative bargaining under incomplete information. Each participant develops its own bargaining strategy based on estimates of the opponent's operating costs and bargaining strategy. Two bargaining models are developed and examples are employed for demonstration. (Author)

    We report a rare case of bilateral hypoplasia of the internal carotid arteries with an associated aneurysm of the basilar tip, studied by CT angiography, MR angiography and digital angiography. The patient became symptomatic with an episode of loss of consciousness, likely due to reduced blood perfusion. The other 20 reported cases of bilateral carotid hypoplasia (only four of which with an associated aneurysm) are reviewed. The findings of noninvasive procedures (including narrowing of the carotid canals on CT) may lead to a correct diagnosis before angiography is performed; they may also help to differentiate angiographic narrowing of the hypoplastic internal carotids from the string sign often observed in some acquired conditions.

    Yokokura, Yuki; Katsura, Seiichiro; Ohishi, Kiyoshi

    A bilateral controller is used to transmit and share haptic information between a master system and a slave system. In a transmission system, the bilateral controller encounters problems in the event of data packet loss and/or disconnections. In this study, a master/slave simulator and environmental data memory are used to solve the problems. In the case of normal operation, the environmental data memory stores force data in a remote side. The control system is operated by the environmental data memory and master/slave simulator when the communication lines are disconnected.

    Common origin of lingual and facial artery is a relatively frequent anatomic varia-tion. Instead, bilateral lingual-facial trunk has been described only sparsely in the literature. In this report authors describe and analyse a case of bilateral common lingual-facial trunk in the context of its anatomical, clinical and embryological implications. We also describe possible consequences in performance of elective and emergent surgical operations and modification in surgical techniques that should be considered. We believe that surgeons should be suspicious for this variation's existence and keep alternative solutions in their armentarium.

    Congenital bladder diverticulum (CBD) is a very uncommon entity in adults. CBD could be unilateral or bilateral and is caused by a congenital weakness in the bladder musculature. CBD is differentiated from the paraureteral or Hutch type of diverticula. A 42-year-old male presented with bilateral Hutch diverticulum and multiple diverticulum calculus on intravenous pyelography. Cystoscopy revealed bladder diverticulum just medial to the left ureteral orifice with multiple calculi; the patient successfully underwent endoscopic laser cystolithotripsy with resolution of his urinary tract infection. To the best of our knowledge, this is the first case report presenting stone formation of CBD in an adult. PMID:26029313

    We report a 30-year-old female patient with a history of hyperpigmented macules of the face since the age of 7 years. The clinical appearance, brown macules in multiple segmental or grouped patterns, was suggested to be agminated lentigines. However, histologic examination of the pigmented macule revealed scattered melanocytes within the dermis. We diagnosed this lesion as a bilateral type of nevus of Ota presenting as agminated lentigines. The differential diagnosis from acquired bilateral nevus of Ota-like macules was made.

    We report the case of a 13-year-old boy who had a bilateral macular injury after playing with a green laser pointer for a duration of 1 minute. Clinical examination revealed a decrease in visual acuity and macular injury in both eyes, and imaging investigations revealed a bilateral macular lesion due to exposure to the laser pointer. At 3 months' follow up, visual function had improved but remained partially impaired. This case emphasizes the importance of cautious and appropriate use of laser pointer devices because of the potential vision-threatening hazards induced by mishandling of these devices.

    1979-08-01

    Cerebral potentials preceding voluntary bilateral simultaneous finger movements were investigated in 19 right-handed young adult subjects, and were compared with unilateral right-sided finger m n the same experiment. With bilateral movements, the Bereitschaftspotential (BP) was not symmetrical or larger over the dominant hemisphere, but surprisingly, it was larger over the minor hemisphere. The BP averaged -3.66 microV (S.D. 1.96) over the left precentral region and -4.82 microV (S.D. 3.73) over the right precentral region in this condition. The difference was significant at 2P less than 0.01. This difference was pronounced in precentral leads but very small and almost missing in parietal leads. The pre-motion positivity (PMP) was well developed and even larger with bilateral than with unilateral (right-sides) movements. At the vertex it averaged +1.33 microV (S.D.4.16) with bilateral movements and only +0.15 microV (S.D. 1.42) with right-sided unilateral movements (2P less than 0.05). With bilateral movements the PMP could be observed in any record, but with unilateral movements it was missing at the left precentral lead, in accordance with previous publications (Deecke et al. 1969, 1976). The motor potential (MP), measured in a bipolar record from left and right precentral leads, was larger with unilateral (-1.25 microV, S.D. 1.33) than with bilateral movements (-0.36 microV, S.D. 0.92). Onset time differences of the BP preceding unilateral and bilateral movements were very small. However, there was a tendency towards earlier onset with unilateral than with bilateral movements (1031 msec, S.D. 358, as compared with 951 msec, S.D. 305). The averaged EMG revealed differences in movement onset. Muscular contraction tended to be earlier in the right than in the left m. flexor indicis in our right-handed subjects, on the average by 16 msec (S.D. 15). With unilateral right-sided movements, the left m. flexor indicis was not silent but showed an abortive mirror activity

    While fibromuscular dysplasia (FMD) is an established cause of secondary hypertension, its association with renal infarction is less well recognized. We report a middle-aged man who presented with complaints of loin pain and severe hypertension. Computed tomography angiography of the abdomen revealed bilateral renal infarction with multiple short-segment arterial dissection compatible with FMD in the absence of systemic vasculitis and other risk factors for thromboembolic events. Bilateral renal infarction complicating FMD is extremely rare and has so far been reported only in a handful of cases. Physicians encountering cases of otherwise unexplained renal infarction/ischemia need to be aware of this complication.

    The authors report a case of bilateral malignant teratoma of the mediastinum in a 40 year old female presenting with chest pain. Two separate bilateral soft tissue masses were noted in the mediastinum at imaging. On the right side, the mass was heterogeneous with large calcification and infiltration of the pericardium. On the left side, the mass was well defined heterogeneous and without evidence of local invasion. The analysis of samples obtained by US guided puncture biopsy and surgical specimen of the two masses confirmed the diagnosis of pluri-cellular malignant teratoma. Mediastinal malignant teratomas represent 1 to 5% of all mediastinal tumors. To our knowledge, no case of synchronous bilateral mediastinal teratoma has never been reported. (authors)

    The aim of the present study was to describe the effect of fibre type and structure as well as NaCl level on the proteolysis index and texture parameters observed in dry-cured meats produced from individual deer muscles. The biceps femoris, semimembranosus and longissimus lumborum muscles were cut from deer main elements, shaped into blocks by trimming off the edges, cured by adding 4, 6 and 8% of salt (w/w) and dried in a ripening chamber for 29days. The results indicated that deer dry-cured muscles with higher percentage of red fibres (type I) showed higher texture parameters, proteolysis index as well as lower moisture losses than muscles with higher amount of white fibres (type IIB). Dry-cured deer muscles with lower NaCl content showed higher values of proteolysis index and lower hardness, cohesiveness, springiness, and chewiness, as well as lower changes in structure elements.

  11. Do patients with incidentally discovered bilateral adrenal nodules represent an early form of ARMC5-mediated bilateral macronodular hyperplasia?

    2016-09-01

    Bilateral adrenal macronodular hyperplasia (BMAH) is a rare form of Cushing's syndrome characterised by the presence of bilateral secretory adrenal nodules and hypercortisolism. Familial studies support a genetic basis for BMAH, and the disease has been linked to mutations in ARMC5, a gene shown to have a tumour suppressor-like action in the development of adrenal nodules. This study aimed to investigate whether ARMC5 mutations play a role in the development of incidentally discovered bilateral adrenal nodules. We investigated 39 patients with incidentally discovered bilateral adrenal nodules >0.8 cm in diameter who underwent extensive biochemical testing to look for signs of subclinical hypercortisolism. Genomic DNA was analysed by Sanger sequencing, using primers targeted to ARMC5 transcripts. Of the 39 patients included in our study, three were identified as having variants in ARMC5. Two of these are unlikely to be clinically significant, but there is evidence that the third mutation, Chr16:g.31476122;c.1778G>C (p.Arg593Pro), may be pathogenic. Another variant, affecting the same amino-acid residue c.1777C>T (p.Arg593Trp), has been identified previously in two studies of BMAH patients, where it has been shown to segregate with disease in one BMAH family. This patient had biochemical evidence of hypercortisolism in the absence of overt Cushing's syndrome, and underwent bilateral adrenalectomy separated in time. The presence of a probably clinically significant mutation in ARMC5 in one patient with bilateral adrenal incidentalomas adds to the growing body of evidence in support of ARMC5 as a critical mediator of adrenal nodule development. In addition, the absence of significant ARMC5 mutations in 38 of our patients represents an important negative finding, demonstrating the degree of variability within the pathogenesis of adrenal nodule development.

  12. MUSCLE ACTIVITY RESPONSE TO EXTERNAL MOMENT DURING SINGLE-LEG DROP LANDING IN YOUNG BASKETBALL PLAYERS: THE IMPORTANCE OF BICEPS FEMORIS IN REDUCING INTERNAL ROTATION OF KNEE DURING LANDING

    Full Text Available Internal tibial rotation with the knee close to full extension combined with valgus collapse during drop landing generally results in non-contact anterior cruciate ligament (ACL injury. The purpose of this study was to investigate the relationship between internal rotation of the knee and muscle activity from internal and external rotator muscles, and between the internal rotation of knee and externally applied loads on the knee during landing in collegiate basketball players. Our hypothesis was that the activity of biceps femoris muscle would be an important factor reducing internal knee rotation during landing. The subjects were 10 collegiate basketball students: 5 females and 5 males. The subjects performed a single-leg drop landing from a 25-cm height. Femoral and tibial kinematics were measured using a 3D optoelectronic tracking system during the drop landings, and then the knee angular motions were determined. Ground reaction forces and muscle activation patterns (lateral hamstring and medial hamstring were simultaneously measured and computed. Results indicated that lower peak internal tibial rotation angle at the time of landing was associated with greater lateral hamstring activity (r = -0.623, p < 0.001. When gender was considered, the statistically significant correlation remained only in females. There was no association between the peak internal tibial rotation angle and the knee internal rotation moment. Control of muscle activity in the lateral to medial hamstring would be an important factor in generating sufficient force to inhibit excessive internal rotation during landing. Strengthening the biceps femoris might mitigate the higher incidence of non-contact ACL injury in female athletes

    Full Text Available A luxação glenoumeral anterior bilateral é uma ocorrência rara. Apresentamos um caso de luxação glenoumeral anterior bilateral com origem após uma queda da própria altura. O interesse desta publicação reside no fato de se tratar de uma raridade clínica com poucos casos descritos na literatura. Paciente do sexo feminino com 89 anos recorre ao serviço de urgência (SU após queda referindo dor intensa e incapacidade de mobilização de ambos os ombros. Ao exame objetivo apresentava sinais clínicos suspeitos de luxação glenoumeral anterior bilateral confirmados por radiografia. Ambas as luxações foram reduzidas no SU pela técnica de Milch modificada, com sucesso. Quando existe uma força simétrica e síncrona sobre os ombros e estes se apresentarem dolorosos e com limite funcional significativo, a suspeita de luxação glenoumeral bilateral, embora rara, é um diagnóstico diferencial a ter em conta.Bilateral anterior glenohumeral dislocation is a rare occurrence. We present a case of bilateral anterior glenohumeral dislocation caused by a fall. The interest in publishing this case is that this is a clinical rarity with few cases reported in the literature. An 89-year-old female patient was brought to the emergency department after a fall, complaining of intense pain in both shoulders and inability to move them. Objective examination showed clinical signs giving the suspicion of bilateral anterior glenohumeral dislocation, which was confirmed by x-ray imaging. Both dislocations were successfully reduced in the emergency department using the modified Milch technique. When a synchronous and symmetrical force has acted on both shoulders and these are painful with significant functional limitation, the suspicion of bilateral glenohumeral dislocation is a differential diagnosis to be considered, even though it is rare.

  15. Security cost allocation under combined bilateral-pool market dispatch

    International Nuclear Information System (INIS)

    Most electricity markets around the world are a combination of bilateral and pool markets, such as NordPool and NYPOOL. In these models, market participants bid into the pool and also make bilateral contracts with each other. This paper addressed the issue of congestion management and security cost allocation in a power pool market model. The basic idea of security cost allocation is to divide the incurred security cost due to congestion relief into pool and bilateral market based on their flow contribution to the congested line. A newly proposed security cost allocation strategy of the combined bilateral-pool market was also presented along with case studies using IEEE-14 bus system that tested the proposed method. Using the proposed method, it was shown that security costs are allocated to market participants at different prices which reflect the load contribution to the security problem. This solves the problem of the uniform security cost allocation in a pure pool market system having uniform pricing, and provides a proper security signal to market participants. 11 refs., 3 tabs., 4 figs

    Full Text Available Herein, we report a case of nontraumatic bilateral rhegmatogenous retinal detachment (RRD during external beam radiotherapy for nonocular tumor, presented as an observational case study in conjunction with a review of the relevant literature. A 65-year-old male was referred to our hospital due to bilateral RRD. He underwent a biopsy for a tumor of the left frontal lobe 4 months prior to presentation, and the tumor had been diagnosed as primary central nerve system B-cell type lymphoma. He received chemotherapy and external beam radiotherapy for 1 month. There were no traumatic episodes. Bilateral retinal detachment occurred during a series of radiotherapies. Simultaneous nontraumatic bilateral retinal detachment is rare. The effects of radiotherapy on ocular functionality, particularly in cases involving retinal adhesion and vitreous contraction, may include RRD. Thus, it is necessary to closely monitor the eyes of patients undergoing radiotherapy, particularly those undergoing surgery for retinal detachment and those with a history of photocoagulation for retinal tears, a relevant family history, or risk factors known to be associated with RRD.

    Objective. To evaluate the treatment results of bilateral alveolar bone grafting (BABG) in patients with bilateral complete clefts of lip and palate.Methods. A retrospective study was performed in 66 bilateral complete cleft lip and palate patients who received the procedure of BABG, among them 15 were primary BABG and 51 were secondary BABG. The patients were further divided into three groups according to age and eruption stage of the canine at the time of surgery. The result of BABG was evaluated on the radiographs. Results. (1)The overall success rate of BABG was 75.0%, with 83.3% and 72.5% for primary and secondary BABG respectively; (2)The marginal bone level was found to be significantly higher in the youngest age group than in the other groups both for primary and secondary BABG; (3)For both primary and secondary BABG, Group C (patients' age more than 16 years) had the least optimal success rate, with 66.7% and 65.4% respectively. Conclusion. Simultaneous primary palate repair and BABG is safe and feasible procedure for treating unoperated bilateral complete cleft lip and cleft palate patients. For both primary and secondary BABG, significantly better results can be achieved if the operation is performed before eruption of the canine.
