    Full Text Available BackgroundGroin dissections result in large wounds with exposed femoral vessels requiring soft tissue coverage, and the reconstructive options are diverse. In this study we reviewed our experience with the use of the pedicled anterolateral thigh and vertical rectus abdominis musculocutaneous flaps in the reconstruction of large groin wounds.MethodsGroin reconstructions performed over a period of 10 years were evaluated, with a mean follow up of two years. We included all cases with large or complex (involving perineum defects, which were reconstructed with the pedicled anterolateral thigh musculocutaneous or the vertical rectus abdominis musculocutaneous (VRAM flaps. Smaller wounds which were covered with skin grafts, locally based flaps and pedicled muscle flaps were excluded.ResultsTwenty-three reconstructions were performed for large or complex groin defects, utilising the anterolateral thigh (n=10 and the vertical rectus abdominis (n=13 pedicled musculocutaneous flaps. Femoral vein reconstruction with a prosthetic graft was required in one patient, and a combination flap (VRAM and gracilis muscle flap was performed in another. Satisfactory coverage was achieved in all cases without major complications. No free flaps were used in our series.ConclusionsThe anterolateral thigh and vertical rectus abdominis pedicled musculocutaneous flaps yielded consistent results with little morbidity in the reconstruction of large and complex groin defects. A combination of flaps can be used in cases requiring extensive cover.

    Full Text Available A 60-year-old male displayed sudden shrinkage of a left free rectus abdominis musculocutaneous flap, which had been grafted to his left maxilla 15 years previously. No post-reconstructive irradiation had been performed, and no late occlusion of the vascular anastomosis, local infection, recurrence of the maxillary cancer, or body weight loss was observed. However, the shrinkage amounted to approximately 50%. This is considerably more than previously reported cases of shrinkage of various free flaps, which ranged between 10% and 25%. The resultant depression was successfully augmented with a right free deep inferior epigastric artery perforator flap. The residual fat volume of the previously grafted shrunken flap was revealed to be compatible with that of the newly harvested contralateral perforator flap. Thus, the volume of the previously grafted flap may reflect the status of the intact contralateral donor site, although the mechanism of sudden flap shrinkage is unclear.

    Endometriosis is characterized by an abnormal existence of functional endometrial tissue outside the uterine cavity, typically occuring within the pelvis of women in reproductive age. We report two cases with endometriosis of the abdominal wall; the first one in the rectus abdominis muscle and the second one in the surgical scar of previous caesarean incision along with the rectus abdominis muscle. Pre-operative evaluation included magnetic resonance imaging. The masses were dissected free from the surrounding tissue and excised with clear margins. Diagnosis of the excised lesions were verified by histopathology. (author)

    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 physical impairments as a result of their reconstruction.

    To evaluate the oncological outcomes of patients with breast cancer after nipple-sparing mastectomy (NSM)/skin-sparing mastectomy (SSM), followed by immediate reconstruction, as compared to conventional mastectomy (CM).SSM/NSM has been increasingly used to treat women with breast cancer who wish to preserve the overlying breast skin, but concern exist regarding its oncological safety due to the potential for residual breast tissue. We report our experience performing SSM/NSM for breast cancer treatment compared to CM with a long follow-up period.All consecutive patients who underwent mastectomy for breast cancer at Asan Medical Center between January 1993 and December 2008 were identified by retrospective medical chart review. The patients who underwent NSM/SSM, followed by immediate breast reconstruction with a pedicled transverse rectus abdominis musculocutaneous flap (TRAM), were compared to the patients who underwent CM in terms of breast-cancer specific survival (BCSS) rate, distant metastasis-free survival (DMFS) rate, and local recurrence (LR) rate.During the study period, 6028 patients underwent mastectomy for breast cancer. Of these, 1032 and 4996 underwent NSM/SSM with TRAM and CM, respectively. Their median follow-up durations were 94.4 (range, 8.1-220.2) and 110.8 (range, 6.1-262.0) months, respectively. Their 5 year BCSS rates were 95.4% and 88.1%, respectively (log-rank, P < .001). Their 5 year DMFS rates were 93.0% and 85.6%, respectively (log-rank, P < .001).Relative to CM, NSM/SSM, followed by immediate breast reconstruction, may be a viable and oncologically safe surgical treatment in selected patients with breast cancer.

    Full Text Available Isolated rectus abdominis muscle endometriosis is very uncommon with less than 20 case reports being published to date since its first description in 1984 by Amato and Levitt. We report another case of isolated rectus abdominis endometriosis in a 37-year-old patient with a previous caesarian section. We also discuss the diagnostic and treatment particularities in these patients. In our case, the treatment was only surgical and currently the patient is disease-free during the 24-month follow-up.

    Myositis ossificans is an ossifying inflammatory lesion occurring within skeletal muscle. Myositis ossificans usually arises in the large muscles of the extremities and this lesion is characterized by progression of mineralization from periphery to center. In the early phase, myositis ossificans simulates malignant soft tissue tumor without dense mineralization. Traumatic myositis ossificans in rectus abdominis muscle has been reported worldwide. The radiologic findings of early active myositis ossificans in rectus abdominis muscle are ill defined heterogenous hypoechoic mass on US, hemorrhage, early strong enhancement and early peripheral mineralization on CT and MR

    Review of the English orthopaedic literature reveals no prior report of endoscopic repair of rectus abdominis tears and/or prepubic aponeurosis detachment. This technical report describes endoscopic reattachment of an avulsed prepubic aponeurosis and endoscopic repair of a vertical rectus abdominis tear immediately after endoscopic pubic symphysectomy for coexistent recalcitrant osteitis pubis as a single-stage outpatient surgery. Endoscopic rectus abdominis repair and prepubic aponeurosis repair are feasible surgeries that complement endoscopic pubic symphysectomy for patients with concurrent osteitis pubis and expand the less invasive options for patients with athletic pubalgia.

    The clinical use and outcome of the rectus abdominis muscle flap to repair prepubic hernias were evaluated retrospectively. Medical records (2002-2007) of 8 dogs that had a rectus abdominis muscle flap to repair traumatic prepubic tendon rupture were reviewed. Only minor donor site complications were noted, including self-limiting ventral and hind-limb swelling. No long-term complications including recurrence of hernia were noted. The results of this study indicate that the rectus abdominis muscle flap is a clinically useful option for repairing prepubic tendon rupture in dogs.

    To report the clinical use of a pedicle flap from the rectus abdominis muscle to repair extensive diaphragmatic tears in dogs with diaphragmatic hernia. Three dogs with a combination of radial and circumferential diaphragmatic tears were studied. The circumferential tear was repaired by suturing the wound edge with the edge at the abdominal wall. A pedicle flap of the rectus abdominis muscle was used for repairing the radial tear. The dogs were examined radiographically for lung and diaphragm appearance and evidence of reherniation at 10 days, and at one, two, and four months after surgery, and fluoroscopically for paradoxical motion of the diaphragm at one and four months. The rectus abdominis muscle pedicle flap was successfully used in all three dogs. The animals recovered uneventfully without evidence of reherniation during the four follow-up months. Fluoroscopic examination revealed no paradoxical motion of the diaphragm. A rectus abdominis muscle pedicle flap can be used for repairing large diaphragmatic defects in dogs.

    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 (Psoccer 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, Psoccer 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. PMID:21541351

  13. SELECTIVE ACTIVATION OF THE RECTUS ABDOMINIS MUSCLE DURING LOW-INTENSITY AND FATIGUING TASKS

    Full Text Available In order to understand the potential selective activation of the rectus abdominis muscle, we conducted two experiments. In the first, subjects performed two controlled isometric exercises: the curl up (supine trunk raise and the leg raise (supine bent leg raise at low intensity (in which only a few motor units are recruited. In the second experiment, subjects performed the same exercises, but they were required to maintain a certain force level in order to induce fatigue. We recorded the electromyographic (EMG activities of the lower and upper portions of the rectus abdominis muscle during the exercises and used spatial-temporal and frequency analyses to describe muscle activation patterns. At low-intensity contractions, the ratio between the EMG intensities of the upper and lower portions during the curl up exercise was significantly larger than during the leg raise exercise (p = 0.02. A cross-correlation analysis indicated that the signals of the abdominal portions were related to each other and this relation did not differ between the tasks (p = 0.12. In the fatiguing condition, fatigue for the upper portion was higher than for the lower portion during the curl up exercise (p = 0.008. We conclude that different exercises evoked, to a certain degree, individualized activation of each part of the rectus abdominis muscle, but different portions of the rectus abdominis muscle contributed to the same task, acting like a functional unit. These results corroborate the relevance of varying exercise to modify activation patterns of the rectus abdominis muscle

    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.

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.

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. The aim of this study was to illustrate a feature of handball injury that, as in tennis and volleyball, is uncommon and so far has not been specifically reported. The phenomenon of contralateral abdominal hypertrophy in handball appears in the dominant arm as in tennis and volleyball.Keywords: rectus abdominis, muscle injury, sonography, MRI, handball

    A five-month-old intact/male Boxer dog was presented 5-days following bite wound trauma to the maxillary region resulting in an oronasal fistula extending from the maxillary canine teeth to the soft palate. Multiple surgical procedures using local, buccal mucosal flaps failed to repair the oronasal fistula. Free tissue transfer of the rectus abdominis myoperitoneal flap using microvascular surgical techniques was successful in providing soft tissue reconstruction of the hard palate area. Complications of these surgical techniques included muscle contraction and subsequent muzzle distortion. Small, refractory oronasal fistulae at the perimeter of the myoperitoneal flap were repaired by primary wound closure.

    Full Text Available The reconstruction of extensive and complex wounds represents a challenging problem for reconstructive surgeon. The reconstructive options to provide cover-age following debridment of these complicated wounds are local, distant flaps, or freetissue transfer. Vertical rectus abdominis flaps have been used succes-sully to repair defects in the groin, hip, perineal, trunk, and breast regions. We encountered flap lymphedema after successful reconstruction of the chronic in-guinal wound with a vertical rectus abdominis (VRAM flap. As far as were able to ascertain, there is no report in the literature related to flap lymphedema.

    Full Text Available BackgroundIf a chronically infected abdominal wound develops, complications such as peritonitis and an abdominal wall defect could occur. This could prolong the patient's hospital stay 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 abdominis muscle myofascial splitting flap was performed on an abdominal wall defect.MethodsFrom 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 after operation, the wound showed signs of infection. Surgery was chosen because the wounds did not resolve with dressing. Debridement was performed along the previous operation wound and dissection of the skin was performed to separate the skin and subcutaneous tissue from the attenuated rectus muscle and Scarpa's fascial layers. Once the anterior rectus sheath and muscle were adequately mobilized, the fascia and muscle flap were advanced medially so that the skin defect could be covered for reconstruction.ResultsUpon 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 terms of function and esthetics at 3 to 6 months post-surgery.ConclusionsUsing a rectus abdominis myofascial splitting flap has many esthetic and functional benefits over previous methods of abdominal defect treatment, and notably, it enabled infection control by reconstruction using muscle.

    Full Text Available Background: Endometriosis of the rectus abdominis muscle is a very rare event and it should be kept in mind in the differential diagnosis of women with abdominal wall mass. Case: 42 year-old G2 P2 patient with uterus didelphis was referred with a painful abdominal wall mass of approximately 4x5 cm size. The mass that has contrast matter enhancement on CT was excised with median laparotomy below the umbilicus. The mass which was thought as endometriosis was excised without remaining any pieces to prevent recurrence and primarily repaired. Discussion: Along with the increasing incidence due to increased cessarean rates the endometrial wall endometriosis is an important diagnosis that should not be omitted. The treatment is surgical resection and to we should take care not to leave any pieces to prevent recurrence especially when it is located atypically.

    In practice cattle may be slaughtered at different combinations of age and weight. As each of these factors could affect meat quality traits, the present work aimed to identify which combination can be expected to increase overall meat quality of m. rectus abdominis of Charolais heifers. Totally, 40 heifers were slaughtered either at 26±1 or at 36±1 months of age. Young heifers were sampled at two different carcass weights (349±12 and 394±8 kg). Old heifers were also sampled at two different carcass weights (397±6 and 451±9 kg). The m. rectus abdominis was excised 24 h postmortem to determine metabolic enzyme activities, myosin heavy-chain isoform proportions, lipid contents, collagen content and collagen solubility. Shear force measurements were evaluated on raw and broiled meat after 14 days of ageing. Meat quality traits scored between 0 and 10 by sensory analysis. Increasing slaughter age from 26 to 36 months had no impact on either raw/broiled shear force (0.31⩽P⩽0.47) and/or meat quality traits (0.62⩽P⩽0.91) or on physicochemical properties of heifer's meat samples. Increasing carcass weight for a similar slaughter age of 26 months had also impact neither on meat quality traits (0.52⩽P⩽0.91) nor on muscular properties. On the contrary, increasing carcass weight for a similar slaughter age of 36 months had induced a decrease of muscular shear force (raw muscle; P=0.009) and a concomitant decrease of total collagen content (P=0.03). Nevertheless, no significant impact on meat quality traits was revealed by the sensorial panel (0.13⩽P⩽0.49). Metabolic enzyme activities (0.13⩽P⩽0.86) and myosin heavy-chain proportions (0.13⩽P⩽0.96) were not significantly impacted by slaughter age and carcass weight. Thus, the impact of increasing carcass weight and/or slaughter age in young Charolais heifers has a limited impact on meat quality traits and associated muscular characteristics.

    Background An important variability of contractile and metabolic properties between muscles has been highlighted. In the literature, the majority of studies on beef sensorial quality concerns M. longissimus thoracis. M. rectus abdominis (RA) is easy to sample without huge carcass depreciation and may appear as an alternative to M. longissimus thoracis for fast and routine physicochemical analysis. It was considered interesting to assess the muscle fibres of M. rectus abdominis in comparison with M. longissimus thoracis (LT) and M. triceps brachii (TB) on the basis of metabolic and contractile properties, area and myosin heavy chain isoforms (MyHC) proportions. Immuno-histochemical, histochemical, histological and enzymological techniques were used. This research concerned two populations of Charolais cattle: RA was compared to TB in a population of 19 steers while RA was compared to LT in a population of 153 heifers. Results RA muscle had higher mean fibre areas (3350 μm2 vs 2142 to 2639 μm2) than the two other muscles. In RA muscle, the slow-oxidative fibres were the largest (3957 μm2) and the fast-glycolytic the smallest (2868 μm2). The reverse was observed in TB muscle (1725 and 2436 μm2 respectively). In RA muscle, the distinction between fast-oxidative-glycolytic and fast-glycolytic fibres appeared difficult or impossible to establish, unlike in the other muscles. Consequently the classification based on ATPase and SDH activities seemed inappropriate, since the FOG fibres presented rather low SDH activity in this muscle in comparison to the other muscles of the carcass. RA muscle had a higher proportion of I fibres than TB and LT muscles, balanced by a lower proportion either of IIX fibres (in comparison to TB muscle) or of IIA fibres (in comparison to LT muscle). However, both oxidative and glycolytic enzyme activities were lower in RA than in TB muscle, although the LDH/ICDH ratio was higher in RA muscle (522 vs 340). Oxidative enzyme activities were

    Full Text Available Background: The aim of this study was to investigate the efficacy of the rectus abdominis myo-peritoneal flap (RAMP technique for the closure and augmentation of small, non-elastic, non-compliant bladder exstrophies. Materials and Methods: The RAMP technique was used in three boys with bladder exstrophy who presented late with small, non-elastic, non-compliant bladder. The clinical outcome, imaging, cystoscopy, biochemical and microbiological studies were assessed during a follow-up of 36 months. Results: Bladder closure and augmentation was achieved in all patients without any complications. There were no urinary tract infections, metabolic problems or electrolyte disturbances and the kidney function remained normal in all patients. Radiography confirmed intact function and anatomy of the urinary tract and cystoscopy showed complete coverage of the inner peritoneal layer of RAMP with uroepithelium. No stone formation or mucous production was detected. Conclusions: The RAMP technique is a good alternative for closing bladder exstrophies and achieves an increase in bladder capacity and compliance. The technique is indicated in the closure of large bladder defects, bladder exstrophies with small, inelastic, non-compliant bladder remnants and failed primary closures.

    Three patients with chronic radiation ulcer treated with free musculocutaneous flap transfer are described. The first patient was a 66-year-old woman who developed sacral ulcer 7 years after radiation combined with surgery for uterine cancer. After debridement of this ulcer, interpositional vein grafts 30 cm in length was used to reconstruct an 'extended' latissimus dorsi musculocutaneous flap. The second patient was a 62-year-old woman. She developed ulcer on her chest 15 years after postoperative irradiation for breast cancer. Radiation damage extended to the myocardium and pulmonary parenchyma. After careful debridement, reconstruction was performed by using the free rectus abdominis musculocutaneous flap. The last patient was a 72-year-old woman. Ulcer of the right axilla developed 19 years after postoperative irradiation for breast cancer. Reconstruction was performed by using a free rectus abdominis musculocutaneous flap. In these patients in whom radiation-damaged tissue was not completely excised, favorable results could be attained by using the transfer of the free musculocutaneous flaps. (N.K.)

    A laparoscopic approach for inguinal hernia repair is now considered the gold standard. Laparoscopic surgery is associated with a significant reduction in postoperative pain. Epidural analgesia cannot be used in patients with perioperative anticoagulant therapy because of complications such as epidural hematoma. As such, regional anesthetic techniques, such as ultrasound-guided rectus sheath block and transversus abdominis plane block, have become increasingly popular. However, even these anesthetic techniques have potential complications, such as rectus sheath hematoma, if vessels are damaged. We report the use of a transperitoneal laparoscopic approach for rectus sheath block and transversus abdominis plane block as a novel anesthetic procedure. An 81-year-old woman with direct inguinal hernia underwent laparoscopic transabdominal preperitoneal inguinal repair. Epidural anesthesia was not performed because anticoagulant therapy was administered. A Peti-needle™ was delivered through the port, and levobupivacaine was injected though the peritoneum. Surgery was performed successfully, and the anesthetic technique did not affect completion of the operative procedure. The patient was discharged without any complications. This technique was feasible, and the procedure was performed safely. Our novel analgesia technique has potential use as a standard postoperative regimen in various laparoscopic surgeries. Additional prospective studies to compare it with other techniques are required. © 2017 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

    Full Text Available Skeletal muscle has been suggested as an important factor in the pathophysiology of metabolic syndrome. During the aging process, muscle mass is lost in specific body parts. However, few studies have investigated the relationship between site-specific muscle loss assessed using computed tomography (CT and metabolic syndrome. This study was conducted to investigate the association between metabolic syndrome and rectus abdominis muscle thickness at the umbilicus level (RAM, which reflects site-specific muscle loss of the abdomen using CT image.This cross-sectional study was conducted on 725 middle-aged Korean men. Anthropometric evaluation and biochemical tests were performed. The RAMs of the subjects were measured from CT images taken at the umbilicus level.The mean RAM (mean ±SD of subjects with metabolic syndrome was 2.46 ±0.01, which was thinner than that of subjects without metabolic syndrome (2.52 ±0.01, p<0.01. Moreover, RAM decreased as the number of metabolic syndrome components increased (p-value for trend<0.01. RAM was positively correlated with body mass index (r = 0.21, p<0.01, skeletal muscle index (r = 0.26, p<0.01, and creatinine (r = 0.12, p<0.01, while RAM was negatively correlated with age(r = -0.11, p<0.01, abdominal circumference(r = -0.22, p<0.01, fasting glucose (r = -0.10, p<0.01, and triglycerides(r = -0.15, p<0.01. Using a stepwise multiple logistic regression analysis, we found that RAM was an independent factor associated with metabolic syndrome (OR: 0.861, 95%CI, 0.779-0.951, p<0.01. The result was not different in the statistical analysis including the components of MS (OR: 0.860, 95% CI, 0.767-0.965, p = 0.01.RAM was associated with metabolic syndrome in middle-aged men. Moreover, site-specific muscle loss at the abdomen, as evaluated by RAM, also may be a predictor of metabolic syndrome like SMI.

    Full Text Available The vertical rectus abdominis myocutaneous (VRAM flap is a versatile and well-established reconstructive technique for many defects created as a result of colorectal and gynecologic extirpation. However, major re-operation in the pelvis following a VRAM flap reconstruction several months later is uncommon, and the safety and integrity of the VRAM flap in this setting has not been described. This case examines VRAM flap preservation during repeat exploratory laparotomy, and a unique view of the VRAM flap during interval exploration. We demonstrate an intact flap after lysis of adhesions with an audible Doppler signal, and maintenance of flap integrity in the postoperative period. This further substantiates its use as a durable rotational flap for perineal tissue defects.

    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 (pinternal oblique (pexternal oblique (pinternal oblique (pexternal oblique: pinternal oblique: p<0.01). The abdominal oblique muscles are the most active during forced expiration. Moreover, 30% PEmax is the minimum intensity required to achieve significant, albeit very slight, muscle activity during expiratory resistance. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Male urinary incontinence is relatively common complication of radical prostatectomy and of posterior urethroplasty following traumatic pelvic fracture. Here, we investigate the use of pedicled rectus abdominis muscle and fascia flap sling of the bulbar urethra for treatment for male-acquired urinary incontinence. Ten patients with acquired urinary incontinence were included in the study. Urinary incontinence was secondary to TURP in three patients and was secondary to posterior urethroplasty performed following traumatic pelvic fracture in seven patients. Pedicled rectus abdominalis muscle and fascial flaps, approximately 2.5 cm wide and 15 cm long, were isolated. The flaps were inserted into a perineal incision through a subcutaneous tunnel. The free end of the flap was sectioned to form two muscle strips, each 3 cm in length, and inserted into the space between bulbar urethra and corpus cavernosa. After adequate sling tension had been achieved, the two strips of muscle were anastomosed around the bulbar urethra using a 2-zero polyglactin suture. The patients were followed up for between 12 and 82 months (mean 42.8 months). Complete continence was achieved with good voiding in seven of the 10 patients. In other three patients achieved good voiding following catheter removal, but incontinence was only moderately improved. A pedicled rectus muscle fascial sling of the bulbar urethra is an effective and safe treatment for male patients with mild to moderate acquired urinary incontinence, but it may not be suitable for severe incontinence or for patients with weak rectus abdominalis muscles.

    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.

    Full Text Available Background: The purpose of the research was to determine the prevalence and location of diastasis recti abdominis muscle (DRA during pregnancy and puerperium in women in the Ljubljana maternity hospital. Methods: The study sample included sixty randomly selected women; forty-five pregnant and postpartum women were recruited from the Ljubljana Maternity Hospital, and fifteen non-pregnant women from the larger Ljubljana area as a control group. All women were examined for the presence or absence of diastasis recti abdominis muscle along with the most and least likely location along the white lines. The measurements were performed by the finger-width method. Results: The findings indicate that the diastasis recti abdominis muscle increases with the progression of pregnancy. In the case of non-pregnant women, the diastasis is not present. The presence of DRA was first observed in the second trimester of pregnancy (9.5 % and was most common in the third trimester (52.4 %. After birth, the incidence decreased (38.1 %. The majority of diastasis recti abdominis cases were observed in the umbilical area (52.6 % in the third trimester. In the puerperium group three days after childbirth the diastasis below the umbilicus was most common (60.0 % and slightly less common above the umbilicus (53.8 %. Conclusion: Diastasis recti abdominis muscle during pregnancy and after childbirth is a common condition. It is therefore recommended that all women should be timely examined for the presence of DRA before and after birth along the linea alba to start timely and adequate physiotherapy treatment. Health professionals as well as sports teachers and coaches who work with pregnant and puerperium women should be educated/trained in the field of testing and treatment of diastasis recti abdominis muscle.

    We performed a randomised controlled double-blinded study of patients having laparoscopic colectomy with bilateral transversus abdominis plane block plus rectus sheath block, comparing a control group receiving 80 ml levobupivacaine 0.2% in saline with a dextran group receiving 80 ml levobupivacaine 0.2% in 8% low-molecular weight dextran. Twenty-seven patients were studied in each group. The mean (SD) maximum plasma concentration of levobupivacaine in the control group (1410 (322) ng.ml(-1) ) was higher than the dextran group (1141 (287) ng.ml(-1) ; p = 0.004), and was reached more quickly (50.6 (30.2) min vs 73.2 (24.6) min; p = 0.006). The area under the plasma concentration-time curve from 0 min to 240 min in the control group (229,124 (87,254) ng.min.ml(-1) ) was larger than in the dextran group (172,484 (50,502) ng.min.ml(-1) ; p = 0.007). The median (IQR [range]) of the summated numerical pain rating score at rest during the first postoperative 24 h in the control group (16 (9-20 [3-31]) was higher than in the dextran group (8 (2-11 [0-18]); p = 0.0001). In this study, adding dextran to levobupivacaine decreased the risk of levobupivacaine toxicity while providing better analgesia. © 2016 The Association of Anaesthetists of Great Britain and Ireland.

Non-randomized selection of 20 continent patients that underwent Macedo's ileum-based reservoir, 10 including Yachia's technique (Study Group) and 10 without this mechanism of continence (Control Group). Demographics and cystometric data were assessed. Conduit's pressure profilometry was obtained by infusing saline through a multichannel catheter, at rest and during Valsalva maneuver. We assessed the pressure: (a) in the bladder; (b) in conduit's proximal segment; and (c) in conduit's distal segment, which is presumably the abdominal wall and crossed muscle strips site. Mean age at surgery was 6.1 years in the Control Group and 7.7 years in the Study Group. There was no statistically significant difference between groups regarding maximum cystometric bladder capacity and leakage point pressure. At rest, the pressure profilometry showed similar results between groups in all segments analyzed. During Valsalva maneuver, pressure profilometry showed similar results between groups in bladder and conduit's proximal segment pressure. In this condition, conduit's distal segment pressure in the Study Group (Mean = 72.9 and Peak = 128.7 cmH2 O) was significantly greater (P continence. © 2014 Wiley Periodicals, Inc.

Materials and Methods: This is a retrospective study of patients who underwent free BERAM flap reconstruction of soft tissue defects of extremity over the last 3 years. We also did a clinical study on 30 volunteers to compare the length of flap available using our design of BERAM flap with the maximum available flap length of LD and ALT flaps, using standard markings. Results: Our clinical experience of nine cases combined with the results of our clinical study has confirmed that our design of BERAM flap consistently provides a flap length which is 32.6% longer than the standard LD flap and 42.2% longer than the standard ALT flap in adults. The difference is even more marked in children. The BERAM flap is consistently reliable as long as the distal end is not extended beyond the mid-axillary line. Conclusion: BERAM flap is simple in design, easy to harvest, reliable and provides the longest possible free skin/myocutaneous flap in the body. It is a useful new alternative for covering long soft tissue defects in the limbs.

    Full Text Available IntroductionSymptomatic umbilical and/or epigastric hernias are often seen concomitantly with rectus abdominis diastasis (RAD, and suture repair of such defects has a high recurrence rate. In the literature there are reports of both endoscopic and open techniques for repair of symptomatic umbilical and/or epigastric hernias in association with RAD. This paper now reports on the early results of a hybrid technique used for reconstruction of the linea alba and mesh augmentation (ELAR plus.Material and methodsBetween 15 June 2015 and 31 January 2016, 40 patients with symptomatic umbilical and /or epigastric hernia and concomitant RAD underwent reconstruction of the linea alba using a hybrid technique involving a small umbilical incision and the use of video endoscopic equipment. The patients comprised 29 men and 11 women with a mean age of 53.6 years and mean BMI of 32.6. The mean operating time was 120 minutes. The mesh had a mean longitudinal extension of 18.6 cm and transverse extension of 9.1 cm. ResultsThirty-day follow-up results are available for all patients. Thirty-seven out of 40 patients (92.5 % experienced no postoperative complication. Two cases of discrete impaired umbilical wound healing and one seroma were successfully managed with conservative treatment. On 30-day follow-up, three out of 40 patients (7.5 % complained of intermittent pain on exertion, and two out of 40 patients (5 % still took painkillers when required.ConclusionEndoscopic-assisted linea alba reconstruction plus mesh augmentation (ELAR plus is a novel minimally invasive procedure for repair of symptomatic umbilical and/or epigastric hernias with concomitant RAD. Reconstruction of the linea alba via a minimally invasive access route is able to restore the normal anatomy of the abdominal wall.

    Systematic literature review. Diastasis of the rectus abdominis muscle (DRAM) has been linked with low back pain, abdominal and pelvic dysfunction. Measurement is used to either screen or to monitor DRAM width. Determining which methods are suitable for screening and monitoring DRAM is of clinical value. To identify the best methods to screen for DRAM presence and monitor DRAM width. AMED, Embase, Medline, PubMed and CINAHL databases were searched for measurement property studies of DRAM measurement methods. Population characteristics, measurement methods/procedures and measurement information were extracted from included studies. Quality of all studies was evaluated using 'quality rating criteria'. When possible, reliability generalisation was conducted to provide combined reliability estimations. Thirteen studies evaluated measurement properties of the 'finger width'-method, tape measure, calipers, ultrasound, CT and MRI. Ultrasound was most evaluated. Methodological quality of these studies varied widely. Pearson's correlations of r = 0.66-0.79 were found between calipers and ultrasound measurements. Calipers and ultrasound had Intraclass Correlation Coefficients (ICC) of 0.78-0.97 for test-retest, inter- and intra-rater reliability. The 'finger width'-method had weighted Kappa's of 0.73-0.77 for test-retest reliability, but moderate agreement (63%; weighted Kappa = 0.53) between raters. Comparing calipers and ultrasound, low measurement error was found (above the umbilicus), and the methods had good agreement (83%; weighted Kappa = 0.66) for discriminative purposes. The available information support ultrasound and calipers as adequate methods to assess DRAM. For other methods limited measurement information of low to moderate quality is available and further evaluation of their measurement properties is required. Copyright © 2015 Elsevier Ltd.

    Rectus abdominis-related groin pain (RAGP) is one of the possible clinical patterns that determine pubalgia. RAGP is one of the typical patterns in footballers and is due to the degeneration and tendinopathy of the distal tendon, at the level of the two pubic tubercles. Intratissue percutaneous electrolysis (EPI) is a novel technique used in the treatment of tendinopathies. The aim of this study was to examine the therapeutic benefits of EPI by contrasting the two basic components that characterize RAGP: painful symptoms and resultant functional deficits. Eight professional footballers at Udinese Calcio Spa Football Club underwent ultrasound-guided EPI intervention. No other type of treatment was combined with EPI. Pain was monitored with the Verbal Rating Scale, while functional deficit was monitored using the Patient Specific Functional Scale. The scales implementation took place before treatment, then 24 hours, 1 week, 1 month and 6 months after the end of treatment. Treatment with EPI produced a complete reduction of pain symptoms in one month and enabled excellent functional recovery for walking and jogging in one week; for getting out of bed, running, jumping and kicking within one month from the end of the treatment. Treatment with ultrasound-guided EPI has shown encouraging clinical results for RAGP. Data are preliminary: considering the limitations of this study more complex design studies are necessary to test the efficacy of the technique. This study introduces the EPI technique for the first time in the treatment of professional footballers suffering from RAGP. Its future use is proposed as a treatment solution, including complementary to conservative treatment.

    Full Text Available Background: Regional anesthetic techniques can be used to alleviate postoperative pain in patients undergoing major upper abdominal surgery. Our aim was to evaluate the efficacy of bilateral ultrasound (US-guided rectus sheath (RS and transversus abdominis plane (TAP blocks for better perioperative analgesia. Patients and Methods: It is a prospective, observer-blinded, randomized clinical study. 40 eligible patients undergoing elective liver resection or Whipple procedure were included. All patients received a standardized anesthetic technique. Group 1 (n = 20 received preincisional US-guided bilateral RS and TAP blocks using 20 ml volume of bupivacaine 0.25% for each, and group 2 (n = 20 received local wound infiltration at end of surgery with 40 ml of bupivacaine 0.25%. A standardized postoperative analgesic regimen composed of intravenous paracetamol and a morphine patient-controlled analgesia (PCA. The use of intraoperative fentanyl and recovery room morphine boluses, PCA-administered morphine, pain scores as well as number of patients′ experienced postoperative nausea and vomiting in the ward at 6 and 24 h were recorded. Results: Group 1 patients received a significantly lower cumulative intraoperative fentanyl, significantly lesser boluses of morphine in postanesthesia care unit, as well, significantly lower cumulative 24 h postoperative morphine dosage than the group 2 patients. Pain visual analog scale scores were significantly lower at both 6 and 24 h postoperatively in TAP group when compared with the no-TAP group. There were no complications related to the TAP block procedures. No signs or symptoms of local anesthetic systemic toxicity were detected. Conclusion: The combination of bilateral US-guided RS and TAP blocks provides excellent perioperative analgesia for major upper abdominal surgery.

    Total pelvic exenteration (TPE) is a rare operation in which the pelvic contents are removed entirely. Several options for pelvic floor and vaginal reconstruction have been described including transverse rectus abdominis musculocutaneous (TRAM) or deep inferior epigastric perforator (DIEP) flaps. The transverse musculocutaneous gracilis (TMG) flap has been introduced for breast reconstruction as a free flap. We adopted the pedicled TMG flap for reconstructions after TPE. To the best of our knowledge, this is the first report of this method in the literature. Between November 2011 and February 2014, 12 patients underwent TPE and reconstruction with unilateral (six patients) or bilateral (six patients) pedicled TMG flaps. Five patients underwent vaginal reconstruction with bilateral TMG flaps. We describe the operative procedure and the outcome of the operation in these patients. The total mean operative times for TPE with or without vaginal reconstruction were 467 ± 12 and 386 ± 59 min, respectively. The TMG flaps had enough vascular tissue and mobility for reconstructing the TPE defects. There was distal edge necrosis in one out of 18 flaps, while the rest survived completely. During the follow-up, complete wound healing with no signs of weakening of the pelvic floor was observed in all cases. Soft-tissue reconstructions are needed to reduce complications associated with TPE, to secure the pelvic floor and to reconstruct the vagina in select patients. The TMG flap is a logical flap choice that does not lead to functional deficits, complicate the abdominal ostomies or weaken the abdominal wall. It reduces the length of operation compared to that of abdominal flaps. IV, therapeutic. Copyright © 2014 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

    Full Text Available Abstract Introduction Rectus sheath hematoma is an uncommon cause of acute abdominal pain. It is an accumulation of blood in the sheath of the rectus abdominis, secondary to rupture of an epigastric vessel or muscle tear. It could occur spontaneously or after trauma. They are usually located infraumblically and often misdiagnosed as acute abdomen, inflammatory diseases or tumours of the abdomen. Case presentation We reported three cases of rectus sheath hematoma presenting with a mass in the abdomen and diagnosed by computerized tomography. The patients recovered uneventfully after bed rest, intravenous fluid replacement, blood transfusion and analgesic treatment. Conclusion Rectus sheath hematoma is a rarely seen pathology often misdiagnosed as acute abdomen that may lead to unnecessary laparotomies. Computerized tomography must be chosen for definitive diagnosis since ultrasonography is subject to error due to misinterpretation of the images. Main therapy is conservative management.

    Full Text Available Brachial plexus is an important group of spinal nerve plexus that supplies the muscles of the upper limb via the ventral rami of the Cervical 5 - Thoracic 1 fibers of the spinal nerves. It is not uncommon to notice the variations during cadaveric dissections in many regions of the body, at different levels, such as, roots, trunks, division, cords, communications, and branches as reported in the literature. Although the nerve supply of the body musculature takes place in the fetal life itself, its course, branching pattern, innervations, and communication can show variable patterns as the fetal development progresses. One such anomaly was noticed during our routine cadaveric dissection in the Department of Anatomy, Jawaharlal Nehru Medical College, Belgaum, showing bilateral absence of the musculocutaneous nerve, which obviously drew the attention of the students of medicine, physiotherapy, and learning clinicians as well.

    Full Text Available Dengue fever, also known as breakbone fever, is an infectious tropical disease caused by the Dengue virus. It is associated with a number of complications, which are well documented. However, Dengue fever associated with rectus sheath hematoma (RSH is a very rare complication. Only one case report has been published prior supporting the association of Dengue fever with RSH. We report a case of Dengue fever who presented with RSH and was successfully treated conservatively. RSH is also an uncommon cause of acute abdominal pain. It is accumulation of blood in the sheath of the rectus abdominis, secondary to rupture of an epigastric vessel or muscle tear.

    During the past 10 years, seven pedicled rectus femoris muscle or musculocutaneous flaps were used to repair lower abdominal defects; three recalcitrant incisional hernias with previous radiotherapy, two long-standing wound infections after synthetic mesh reconstruction, one posttraumatic wall defect and one metastatic tumor. There were two flap complications, one skin paddle necrosis and one wound infection. There was no significant disability of the donor limb encountered. During the two-year and seven month average follow-up, there was no recurrence of the problems except for one minor fascial dehiscence in the patient with metastatic abdominal wall tumor. Easy approach, rapid harvest, relatively large and reliable overlying fascia lata, a single dominant neurovascular pedicle, easy primary closure of the donor site, and minimal donor site morbidity all make the rectus femoris flap a good alternative flap for lower abdominal wall reconstruction. It is especially useful in a condition where synthetic mesh would be unsuitable for defects with infection or recurrent incisional hernia after radiotherapy. (author)

    Detailed knowledge of course and distribution of nerves in the axilla and arm is very important in the management of nerve injuries particularly in case of their variations. Bilateral absence of the musculocutaneous nerve was found during routine dissection in a male cadaver. The dissected part was cleared to see the distribution of the muscles of the arm. The muscles of the flexor compartment were supplied by the median nerve, instead of the musculocutaneous nerve. The present case report of this anatomical variation of the nerves should help in management of nerve injuries in the axilla or the arm. PMID:25386419

    Full Text Available ABSTRACT The clinical and surgical importance of anatomical knowledge of the musculocutaneous nerve and its variations is due to the fact that one of the complications in many upper-limb surgical procedures involves injury to this nerve. During routine dissection of the right upper limb of a male cadaver, we observed an anatomical variation of this nerve. The musculocutaneous nerve originated in the lateral cord and continued laterally, passing under the coracobrachialis muscle and then continuing until its first branch to the biceps brachialis muscle. Just after this, it supplied another two branches, i.e. the lateral cutaneous nerve of the forearm and a branch to the brachialis muscle, and then it joined the median nerve. The median nerve followed the arm medially to the region of the cubital fossa and then gave rise to the anterior intermediate nerve of the forearm. The union between the musculocutaneous nerve and the median nerve occurred approximately at the midpoint of the arm and the median nerve. Given that either our example is not covered by the classifications found in the literature or that it fits into more than one variation proposed, without us finding something truly similar, we consider this variation to be rare.

    The retroperitoneum is rich in vascular structures and can harbor large hematomas, traumatic or spontaneous. The management of retroperitoneal hematomas depends on the mechanism of injury and whether they are pulsatile/expanding. Rectus sheath hematomas are uncommon abdominal wall hematomas secondary to trauma to the epigastric arteries of the rectus muscle. The common risk factors include anticoagulation, strenuous exercise, coughing, coagulation disorders, and invasive procedures on/through the abdominal wall. The management is largely supportive, with the reversal of anticoagulation and transfusions; angioembolization may be necessary. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Port site wound infection, abdominal wall hematoma and intraabdominal abscess formation has been reported after laparoscopic appendicectomy. We describe here a rectus sheath abscess which occurred three weeks after the laparoscopic appendicectomy. It was most likely the result of secondary infection of the rectus sheath hematoma due to bleeding into the rectus sheath from damage to the inferior epigastric arteries or a direct tear of the rectus muscle. As far as we are aware this complication has not been reported after laparoscopic appendicectomy.

    Full Text Available Necrotizing fasciitis is a life-threatening, soft tissue infection and an early diagnosis is needed to permit a prompt surgical and medical intervention. Due to the high fatal potential of the disease complications, the radiologist should distinguish necrotizing fasciitis from the most common soft tissue infections, in order to permit a prompt surgical and medical treatment. We present a case of a wide necrotizing fasciitis who presented at our emergency department and we also provide the basic tools, through a review of the literature, for the general radiologist to distinguish, with computed tomography and magnetic resonance imaging, necrotizing fasciitis from the most common infections that could present during our routine practice.

    We present a case of extensive actinomycosis of the face, which appeared after dental surgery. Since antibiotic therapy was ineffective, the lesion was radically resected, and the skin, soft tissue and facial nerve were reconstructed using a free rectus abdominis musculocutaneous flap and simultaneously harvested intercostal nerves. Successful reanimation of the face was achieved 14 months postoperatively.

    Experimental laboratory study supplemented with a repeated case study. To examine bilateral muscle activity of the deep abdominals in response to rapid arm raising, specifically to examine the laterality and directional specificity of feedforward responses of the transversus abdominis (TrA). Based on the feedforward responses of trunk muscles during rapid arm movements, authors have concluded that the deep trunk muscles have different control mechanisms compared to the more superficial muscles. It has been proposed that deep trunk muscles such as TrA contribute substantially to the stability of the lumbar spine and that this is achieved through simultaneous bilateral feedforward activation. These inferences are based on unilateral fine-wire electromyographic (EMG) data and there are limited investigations of bilateral responses of the TrA during unilateral arm raising. Bilateral fine-wire and surface EMG data from the anterior deltoid, TrA, obliquus internus (OI), obliquus externus, biceps femoris, erector spinae, and rectus abdominis during repeated arm raises were recorded at 2 kHz. EMG signal linear envelopes were synchronized to the onset of the anterior deltoid. A feedforward window was defined as the period up to 50 ms after the onset of the anterior deltoid, and paired onsets for bilateral muscles were plotted for both left and right arm movements. Trunk muscles from the group data demonstrated differences between sides (laterality), which were systematically altered when alternate arms were raised (directional specificity). This was clearly evident for the TrA but less obvious for the erector spinae. The ipsilateral biceps femoris and obliquus externus, and contralateral OI and TrA, were activated earlier than the alternate side for both right and left arm movements. This was a consistent pattern over a 7-year period for the case study. Data for the rectus abdominis derived from the case study demonstrated little laterality or directionally specific

    Full Text Available Phrenic nerve transfer is a major dynamic treatment used to repair brachial plexus root avulsion. We analyzed 72 relevant articles on phrenic nerve transfer to repair injured brachial plexus that were indexed by Science Citation Index. The keywords searched were brachial plexus injury, phrenic nerve, repair, surgery, protection, nerve transfer, and nerve graft. In addition, we performed neurophysiological analysis of the preoperative condition and prognosis of 10 patients undergoing ipsilateral phrenic nerve transfer to the musculocutaneous nerve in our hospital from 2008 to 201 3 and observed the electromyograms of the biceps brachii and motor conduction function of the musculocutaneous nerve. Clinically, approximately 28% of patients had brachial plexus injury combined with phrenic nerve injury, and injured phrenic nerve cannot be used as a nerve graft. After phrenic nerve transfer to the musculocutaneous nerve, the regenerated potentials first appeared at 3 months. Recovery of motor unit action potential occurred 6 months later and became more apparent at 12 months. The percent of patients recovering ′excellent′ and ′good′ muscle strength in the biceps brachii was 80% after 18 months. At 12 months after surgery, motor nerve conduction potential appeared in the musculocutaneous nerve in seven cases. These data suggest that preoperative evaluation of phrenic nerve function may help identify the most appropriate nerve graft in patients with an injured brachial plexus. The functional recovery of a transplanted nerve can be dynamically observed after the surgery.

    2018-06-01

    Full Text Available Purpose: We present the first reported case of Waldenstrom macroglobulinemia in the right superior rectus causing diplopia. Observations: A 72-year-old man with a 6-month history of untreated asymptomatic Waldenstrom macroglobulinemia presented with 2 years of diagonal binocular diplopia that was previously thought to be due to ocular myasthenia gravis. Examination showed mild right proptosis and right hypotropia, and MRI revealed a focal lesion of the right superior rectus muscle. Orbital biopsy was performed, and histopathology showed lymphoplasmacytic infiltration among the skeletal muscle fibers of the rectus muscle. Immunostaining confirmed a B-cell preponderance, along with more extensive staining for IgM than IgG, and in situ hybridization confirmed lambda restriction. These findings corresponded with those of his previous bone marrow biopsy, confirming Waldenstrom macroglobulinemia as the etiology for the extraocular muscle mass. Conclusions and Importance: Lymphoma of an extraocular muscle is a rare manifestation of orbital lymphoma, and the tumors are usually mucosa-associated lymphoid tissue (MALT lymphomas (i.e. extranodal marginal zone lymphomas. There are 4 previous reports of lymphoplasmacytic lymphoma of an extraocular muscle; however this is the first reported case of such a lesion in a patient with concurrent Waldenstrom macroglobulinemia at the time of diagnosis.

    We report the case of a 21-year-old woman who presented with a drooping right upper eyelid and smaller-appearing right eye, evident since birth. Her visual acuity was 20/30 in the right eye and 20/20 in the left eye. In primary gaze she had a hypotropia of 25 Δ , with a marked elevation limitation and associated true upper lid ptosis of 3 mm. Under local anesthesia, the lateral rectus muscle was transposed to the superior rectus muscle and was augmented by a nonabsorbable suture attaching the superior rectus muscle and lateral rectus muscle 8 mm posterior to the insertion, accompanied by an inferior rectus recession. One year after surgery she was orthophoric in primary position and showed improvement in elevation. The surgical procedure can be performed at the same time as the inferior rectus recession and reduces the risk of anterior segment ischemia.

    Vandana Tomar

    2012-01-01

    Full Text Available Brachial Plexus is formed by the union of the anterior rami of cervical 5, 6, 7, 8 and thoracic 1 nerves. These nerves unite and divide to form the key nerves innervating the upper limb. Variations in the course of these nerves are clinically important to anesthetists, neurologists and orthopedicians. We report bilateral variations in the arterial and neural structures in the upper limb of a 65 year old cadaver. The muscles of the arm on one side were innervated by the median nerve with absence of musculocutaneous. While on the other side the musculocutaneous nerve contributed to the formation of the median nerve. There was a presence of high bifurcation of brachial artery on both sides. Knowledge of such variations in the innervations of muscles and the arterial supply of the limbs are important to remember before performing any reconstructive procedures or interventions on the limb.

    The abdominal wall is a significant source of pain after abdominal surgery. Anterior abdominal wall analgesia may assist in improving postoperative analgesia. We have recently described a novel approach to block the abdominal wall neural afferents via the bilateral lumbar triangles of Petit, which we have termed a transversus abdominis plane block. The clinical efficacy of the transversus abdominis plane block has recently been demonstrated in a randomized controlled clinical trial of adults undergoing abdominal surgery.

    Until recently, no single, universally accepted surgical method has existed for all types of concealed penis repairs. We describe a new surgical technique for repairing concealed penis by using an advanced musculocutaneous scrotal flap. From January 2010 to June 2014, we evaluated 12 patients (12-40 years old) with concealed penises who were surgically treated with an advanced musculocutaneous scrotal flap technique after degloving through a ventral approach. All the patients were scheduled for regular follow-up at 6, 12, and 24 weeks postoperatively. The satisfaction grade for penile size, morphology, and voiding status were evaluated using a questionnaire preoperatively and at all of the follow-ups. Information regarding complications was obtained during the postoperative hospital stay and at all follow-ups. The patients' satisfaction grades, which included the penile size, morphology, and voiding status, improved postoperatively compared to those preoperatively. All patients had penile lymphedema postoperatively; however, this disappeared within 6 weeks. There were no complications such as skin necrosis and contracture, voiding difficulty, or erectile dysfunction. Our advanced musculocutaneous scrotal flap technique for concealed penis repair is technically easy and safe. In addition, it provides a good cosmetic appearance, functional outcomes and excellent postoperative satisfaction grades. Lastly, it seems applicable in any type of concealed penis, including cases in which the ventral skin defect is difficult to cover.

    To describe musculocutaneous MR-findings responsible for disability in chronic graft-versus-host disease (cGVHD) after allogeneic hematopoietic cell transplantation (HCT). Between June 2005 and February 2008, we performed whole-body musculoskeletal magnetic resonance imaging (MRI; n = 12) or regional MRI (n = 4) in 16 consecutive patients presenting with disabling sclerodermatous cGVHD (e.g., skin edema, fixed deep dermal sclerosis, joint contractures, painful muscular contractures, or myalgia). In all patients, MRI showed musculocutaneous abnormalities reflecting different degrees of inflammation and collagen tissue involvement of the skin (n = 10), subcutaneous fat tissue (n = 13), muscle fasciae (n = 16), subfascial muscular septae (n = 6), or findings compatible with myositis (n = 3). The most frequently involved muscle fasciae comprised those of the vastus lateralis muscle (n = 12), biceps femoris muscle (n = 11), gastrocnemius medialis muscle (n = 8), serratus anterior muscle, and latissimus dorsi muscle (each, n = 5). Increased signal of involved tissues on STIR-images and fat-saturated postgadolinium T1-weighted images represented the most frequent MR-signal abnormalities. MR imaging of musculocutaneous cGVHD allows accurate evaluation including assessment of deep tissue infiltration and assists in the differential diagnosis. (orig.)

    The purpose of this study was to determine the position of rectus muscle pulleys in Japanese eyes and to evaluate the effect of oblique muscle surgery on rectus muscle pulleys. Quasi-coronal plane MRI was used to determine area centroids of the 4 rectus muscles. The area centroids of the rectus muscles were transformed to 2-dimensional coordinates to represent pulley positions. The effects of oblique muscle surgery on the rectus muscle pulley positions in the coronal plane were evaluated in 10 subjects with cyclovertical strabismus and, as a control, pulley locations in 7 normal Japanese subjects were calculated. The mean positions of the rectus muscle pulleys in the coronal plane did not significantly differ from previous reports on normal populations, including Caucasians. There were significant positional shifts of the individual horizontal and vertical rectus muscle pulleys in 3 (100%) patients with inferior oblique advancement, but not in eyes with inferior oblique recession and superior oblique tendon advancement surgery. The surgical cyclorotatory effect was significantly correlated with the change in the angle of inclination formed by the line connecting the vertical rectus muscles (p=0.0234), but weakly correlated with that of the horizontal rectus muscles. The most important factor that affects the pulley position is the amount of ocular torsion, not the difference in surgical procedure induced by oblique muscle surgery. (author)

  12. Musculocutaneous nerve substituting for the distal part of radial nerve: A case report and its embryological basis

    Full Text Available In the present case, we have reported a unilateral variation of the radial and musculocutaneous nerves on the left side in a 64-year-old male cadaver. The radial nerve supplied all the heads of the triceps brachii muscle and gave cutaneous branches such as lower lateral cutaneous nerve of the arm and posterior cutaneous nerve of forearm. The radial nerve ended without continuing further. The musculocutaneous nerve supplied the brachioradialis, extensor carpi radialis longus and extensor carpi radialis brevis muscles. The musculocutaneous nerve divided terminally into two branches, superficial and deep. The deep branch of musculocutaneous nerve corresponded to usual deep branch of the radial nerve while the superficial branch of musculocutaneous nerve corresponded to usual superficial branch of the radial nerve. The dissection was continued to expose the entire brachial plexus from its origin and it was found to be normal. The structures on the right upper limb were found to be normal. Surgeons should keep such variations in mind while performing the surgeries of the upper limb.

    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.

    We report on a patient with a recurrence of oral cancer involving a cervical lymph node. The patient's postexcision cervical skin defect was nearly circular in shape, and the size was about 12 cm in diameter. The defect was successfully reconstructed with a boomerang-shaped pectoralis major musculocutaneous flap whose skin paddle included multiple intercostal perforators of the internal mammary vessels. This flap design is effective for reconstructing an extensive neck skin defect and enables primary closure of the donor site with minimal deformity.

    Background/aim Diastasis recti abdominis (DRA) is defined as a separation of the 2 muscle bellies of rectus abdominis. To date there is scant knowledge on prevalence, risk factors, and consequences of the condition. The present study aimed to investigate the prevalence of DRA during pregnancy and post partum, presence of possible risk factors, and the occurrence of lumbopelvic pain among women with and without DRA. Methods This prospective cohort study followed 300 first-time pregnant women from pregnancy till 12 months post partum. Data were collected by electronic questionnaire and clinical examinations. DRA was defined as a palpated separation of ≥2 fingerbreadths either 4.5 cm above, at or 4.5 cm below the umbilicus. Women with and without DRA were compared with independent samples Student's t-test and χ2/Fisher exact test, and OR with significance level >0.05. Results Prevalence of DRA was 33.1%, 60.0%, 45.4%, and 32.6% at gestation week 21, 6 weeks, 6 months and 12 months post partum, respectively. No difference in risk factors was found when comparing women with and without DRA. OR showed a greater likelihood for DRA among women reporting heavy lifting ≥20 times weekly (OR 2.18 95% CI 1.05 to 4.52). There was no difference in reported lumbopelvic pain (p=0.10) in women with and without DRA. Conclusions Prevalence of mild DRA was high both during pregnancy and after childbirth. Women with and without DRA reported the same amount of lumbopelvic pain 12 months post partum. PMID:27324871

  19. Absence of the musculocutaneous nerve: a rare anatomical variation with possible clinical-surgical implications

    Directory of Open Access Journals (Sweden)

    José Humberto Tavares Guerreiro Fregnani

    Full Text Available CONTEXT: The musculocutaneous nerve is one of the terminal branches of the lateral fasciculus of the brachial plexus, and is responsible for innervation of the flexor musculature of the elbow and for skin sensitivity on the lateral surface of the forearm. Its absence has been described previously, but its real prevalence is unknown. CASE REPORT: A case of absence of the musculocutaneous nerve that was observed during the dissection of the right arm of a male cadaver is described. The area of innervation was supplied by the median nerve. From this, three branches emerged: one to the coracobrachialis muscle, another to the biceps brachii muscle and the third to the brachialis muscle. This last branch continued as a lateral antebrachial cutaneous nerve. This is an anatomical variation that has clinical-surgical implications, considering that injury to the median nerve in this case would have caused unexpected paralysis of the flexor musculature of the elbow and hypoesthesia of the lateral surface of the forearm.

    Rogério De Oliveira Gonçalves

    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 analgesic efficacy of the transversus abdominis plane peripheral nerve block following abdominal tissue breast reconstruction has not been studied in a randomized controlled trial. The authors conducted a double-blind, placebo-controlled, 1:1 allocation, two-arm parallel group, superiority design, randomized controlled trial in patients undergoing microsurgical abdominally based breast reconstruction. Intraoperatively, epidural catheters were inserted under direct vision through the triangle of Petit on both sides of the abdomen into the transversus abdominis plane just before rectus fascial closure. Patients received either bupivacaine (study group) or saline (placebo group) through the catheters for 2 postoperative days. All patients received hydromorphone by means of a patient-controlled analgesic pump. The primary outcome was the difference in the parenteral opioid consumption on each postoperative day between the groups. The secondary outcome measures included the following: total in-hospital opioid; antinausea medication; pain, nausea, and sedation scores; Quality of Recovery Score; time to ambulation; and hospital stay duration. Between September of 2011 and June of 2013, 93 patients were enrolled: 49 received bupivacaine and 44 received saline. There were 11 postoperative complications (13 percent); none were related to the catheter. Primary outcomes were completed by 85 of 93 patients (91.3 percent); the mean parenteral morphine consumption was significantly reduced on postoperative day 1 in the bupivacaine group (20.7±20.1 mg) compared with 30.0±19.1 mg in the control group (p=0.02). There were no significant differences in secondary outcomes. Following abdominally based breast reconstruction, transversus abdominis plane peripheral nerve block is safe and significantly reduces morphine consumption in the early postoperative period.

    Anomalies in the frontal lobe can interfere with visual function by compression of the optic chiasm and nerve. The gyrus rectus is located at the anterior cranial fossa floor superior to the intracranial optic nerves and chiasm. Compression of these structures by the gyrus rectus is often caused by neoplastic or dysplastic growth in the area. We report a rare case of a herniated gyrus rectus impinged on the optic chiasm and nerve without a clear pathological cause for the herniation. Copyright © 2016 Elsevier B.V. All rights reserved.

    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.

    2017-03-01

    Full Text Available The brachial plexus innervates the upper extremities. While variations in the formation of the brachial plexus and its terminal branches are quite common, it is uncommon for the median nerve to innervate the muscles of the arm. During the dissection of an elderly male cadaver at the Department of Anatomy, All India Institute of Medical Sciences, New Delhi, India, in 2016, the coracobrachialis muscle was found to be supplied by a direct branch from the lateral root of the median nerve and the musculocutaneous nerve was absent. The branches of the median nerve supplied the biceps brachii and brachialis muscles and the last branch continued as the lateral cutaneous nerve of the forearm. These variations may present atypically in cases of arm flexor paralysis or sensory loss on the lateral forearm. Knowledge of these variations is important in surgeries and during the administration of regional anaesthesia near the shoulder joint and upper arm.

    2005-01-01

    Full Text Available During dissection of a 55-year-old female cadaver, we observed that three nerve roots contributed to the formation of Median nerve in her right upper limb. Along with this variation, absence of Musculocutaneous nerve was noticed. The muscles of front of arm i.e. Biceps Brachii, Brachialis and Coracobrachialis received their nerve supply from Median nerve. The Lateral cutaneous nerve of forearm was derived from Median nerve. Also an accessory head of Biceps Brachii muscle was present in the right arm of the same cadaver. It is extremely important to be aware of these variations while planning a surgery in the region of axilla or arm as these nerves are more liable to be injured during operations.

  7. Combined Continuous Paravertebral and TAP Blocks for Pain Management after TRAM Flap Breast Reconstruction: A Report of Two Cases

    2015-03-01

    Full Text Available Transverse Rectus Abdominis Musculocutaneous (TRAM flap surgery is a prolonged and extensive procedure that requires multiple incisions. Recently, Transverse Abdominis Plane (TAP blocks have been found to be reliable method of providing regional analgesia for lower abdominal surgery and paravertebral block for pain management after breast surgery. Since the TRAM flap surgery involves both abdomen and thorax, the combination of these two blocks to manage post operative pain could be effective. This manuscript is one of the initial cases reporting of the use of these techniques in which triple catheters with ropivacaine infusion in breast reconstruction surgery were successfully used with reduced pain scores and opioid consumption.

    The subcostal transverse abdominis plane (SCTAP) block is the deposition of local anesthetic in the transverse abdominis plane inferior and parallel to the costal margin. There is a growing consensus that the SCTAP block provides better analgesia for upper abdominal incisions than the traditional transverse abdominis plane block. In addition, when used as part of a four-quadrant transverse abdominis plane block, the SCTAP block may provide adequate analgesia for major abdominal surgery. The purpose of this review is to discuss the SCTAP block, including its indications, technique, local anesthetic solutions, and outcomes.

    2003-03-01

    A species-specific nested polymerase chain reaction (PCR) assay was used to investigate the occurrence of Campylobacter gracilis and C. rectus in primary root canal infections. Samples were collected from 57 single-rooted teeth with carious lesions, necrotic pulps and radiographic evidence of periradicular disease. Twenty-eight cases were diagnosed as chronic asymptomatic periradicular lesions, 12 cases as acute apical periodontitis, and 17 cases as acute periradicular abscess. DNA was extracted from the samples and initially amplified using universal 16S rDNA primers. A second round of amplification using the first PCR products was performed to specifically detect C. gracilis or C. rectus in the samples. Campylobacter gracilis and C. rectus were, respectively, detected in 21.4 (6 of 28) and 30% (6 of 20) of the root canals associated with chronic asymptomatic periradicular lesions. Campylobacter gracilis was found in 16.7% (2 of 12) of the cases diagnosed as acute apical periodontitis, whilst C. rectus was found in 33.3% (two of six cases). In the abscessed cases, C. gracilis and C. rectus were detected in 23.5 (4 of 17) and 11.8% (2 of 17) of the cases, respectively. No association of these species with clinical symptoms was observed (P > 0.01) In general, species-specific nPCR allowed the detection of C. gracilis in 21.1% (12 of 57) and C. rectus in 23.3% (10 of 43)of the samples taken from primary endodontic infections. Findings confirmed the assertion that both C. gracilis and C. rectus participate in infections of endodontic origin and suggest a pathogenetic role with regard to periradicular diseases.

    Restoring elbow flexion remains the first step in the management of total palsy of the brachial plexus. Non avulsed upper roots may be grafted on the musculocutaneous nerve. When this nerve is entirely grafted, some motor fibres regenerate within the sensory fibres quota. Aiming potential utilization of these lost motor fibres, we attempted suturing the sensory branch of the musculocutaneous nerve onto the deep branch of the radial nerve. The objective of our study was to assess the anatomic feasibility of such direct suturing of the terminal sensory branch of the musculocutaneous nerve onto the deep branch of the radial nerve. The study was carried out with 10 upper limbs from fresh cadavers. The sensory branch of the musculocutaneous muscle was dissected right to its division. The motor branch of the radial nerve was identified and dissected as proximally as possible into the radial nerve. Then, the distance separating the two nerves was measured so as to assess whether direct neurorraphy of the two branches was feasible. The excessive distance between the two branches averaged 6 mm (1-13 mm). Thus, direct neurorraphy of the sensory branch of the musculocutaneous nerve and the deep branch of the radial nerve was possible. When the whole musculocutaneous nerve is grafted, some of its motor fibres are lost amongst the sensory fibres (cutaneous lateral antebrachial nerve). By suturing this sensory branch onto the deep branch of the radial nerve, "lost" fibres may be retrieved, resulting in restoration of digital extension. Copyright © 2011 Wiley-Liss, Inc.

    2006-01-01

    To describe the MR imaging findings of acute and chronic rectus femoris origin (RFO) injuries. A retrospective review of pelvic and hip MR imaging procedures was performed over a 4-year period for detection of cases with injuries to the RFO. Subjects were classified as having either acute or chronic symptoms. MR imaging studies, radiographs, CT scans, radiology reports, medical records, and operative notes were reviewed. Imaging analysis was directed to assess injuries affecting the direct and indirect heads of the RFO. Concurrent osseous, cartilaginous and musculotendinous injuries were tabulated. The incidence of RFO injuries on MR imaging was 0.5% (17/3160). With the exception of one case of anterior inferior iliac spine apophysis avulsion and partial tear of the direct head of RFO, all subjects had indirect head of RFO injuries (acute injury 8/9, chronic injury 8/8). Partial tear of the direct head of RFO was less frequently seen (acute injury 3/9, chronic injury 2/8). Partial tears of the conjoint tendon were least frequent (acute 1/9, chronic 2/8). No full-thickness tears of the RFO were noted. Associated labral tears were seen in only one case, with no other concomitant abnormality of the articular cartilage or surrounding soft tissues. All RFO injuries were treated non-operatively. Injuries of the RFO are uncommon on MR examinations of pelvis/hips and may occur in a sequence progressing from indirect head injury to involvement of direct head and conjoint tendon in more severe cases.

    Transversus abdominis plane (TAP) blocks have been reported to be an effective method of providing analgesia after abdominal surgery. To perform a prospective audit on the effectiveness of a novel technique of providing continuous transversus abdominis plane (TAP) analgesia in patients undergoing emergency and elective abdominal surgery. Prospective single center audit over a 3-year period. University hospital. One hundred twenty-four American Society of Anesthesiologists I to IV adult patients presenting for elective as well as emergency abdominal surgery in whom epidural analgesia was contraindicated or refused. Four quadrant TAP blocks and continuous TAP analgesia. Numerical rating scale pain scores at rest and on coughing, nausea scores, satisfaction scores, complications, frequency of analgesia failure, therapeutic failure with continuous TAP analgesia and opioid consumption. One hundred twenty-four patients who received continuous TAP analgesia were audited. This included 34 patients for elective open surgery, 36 patients for emergency laparotomy, and 54 patients who underwent elective laparoscopic colorectal surgery. Surgical incision was within the dermatomal limit of the block in 70% of the patients (88/124). Therapeutic failure with the technique was 10%. Frequency of analgesic failure over the 48-hour period was none in 39% and below 5 episodes in 57%. Four quadrant transversus abdominis plane blocks and continuous TAP analgesia is an effective technique for providing postoperative analgesia after abdominal surgery. It has the potential to be used as a sole analgesic technique when the surgical incision is within its dermatomal limit. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available We described the utility of computed tomography (CT angiography in detection of bleeding vessels for a rapid percutaneous arterial embolization of the spontaneous rectus sheath hematoma. A 70-year-old woman comes to our attention with acute abdominal pain and a low hemoglobin level. An unenhanced CT was performed demonstrating a large rectus sheath hematoma. A conservative management was initially established. Despite this therapy, the abdominal pain increased together with a further decrease of hemoglobin values. A CT angiography was then performed, demonstrating an active bleeding within the hematoma and addressing the patient to a rapid percutaneous arterial embolization.

    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.

  16. Recurrent vulvar carcinoma: complex surgical treatment via perineal excision and reconstruction with musculocutaneous flap

    Full Text Available Vulvar cancer is a malignant disease having a low frequency and with well-established surgical and oncological treatments based on the stage of the disease. The most important therapeutic problem encountered is represented by cases of perineal local regional recurrence, which are common in patients with large primary tumors and can occur even if the margins of the resection had no tumoral invasion. We present a case study of a 64-year-old patient diagnosed one year ago with squamous vulvar carcinoma (G3 for which a vulvectomy was performed after neoadjuvant radiotherapy. The patient later developed local recurrence with invasion of the anal sphincter, creating a delicate problem regarding a surgical approach. The size and the extent of the recurrent tumor required a complex surgical intervention using a mixed surgical team of general surgeons and plastic surgeons. Surgical intervention with a large excision of the recurrent cancer along with amputation of the inferior rectum via perineal route, and creation of a left iliac anus was performed. The perineal defect was covered via a musculocutaneous flap using the gracilis muscle. The immediate post-operative evolution was favorable.

    Full Text Available During routine dissection by medical undergraduates, third head of the biceps brachii muscle was found on the left side of a 75-year-old male cadaver in a total of 48 arms dissected in Department of Anatomy Armed Forces Medical College, Pune. Biceps brachii is a muscle of arm having two heads hence the name. The most frequent variation of the muscle is in the number of heads with a prevalence range of 9.1-22.9%. The origin of the supernumerary head in this case was from the humerus, between the insertion of the coracobrachialis and the upper part of the origin of the brachialis, and also from the medial intermuscular septum. The supernumerary head joined the common belly. It was supplied by the musculocutaneous nerve which after emerging from brachialis pierced it near the middle and terminated by finally supplying the biceps belly. In our study, 2.08% (1 of 48 of male cadavers were found to have the third head of biceps. The incidence of this variation can be as much as 10% as, shown in previous studies on Indian population, as reported in standard textbooks of anatomy.

    Capsular contracture is a common complication associated with implant-based breast reconstruction and augmentation leading to pain, displacement, and rupture. After capsulectomy and implant exchange, the problem often reappears. We performed 52 deepithelialized free transverse musculocutaneous gracilis (TMG) flaps in 33 patients for tertiary breast reconstruction or augmentation of small- and medium-sized breasts. The indications for implant removal were unnatural feel and emotion of their breasts with foreign body feel, asymmetry, pain, and sensation of cold. Anyway, most of the patients did not have a severe capsular contracture deformity. The TMG flap is formed into a cone shape by bringing the tips of the ellipse together. Depending on the contralateral breast, the muscle can also be shaped in an S-form to get more projection if needed. The operating time for unilateral TMG flap breast reconstruction or augmentation was on average 3 hours and for bilateral procedure 5 hours. One patient had a secondary revision of the donor site due to disruption of the normal gluteal fold. Eighty percent of the unilateral TMG flap reconstructions had a lipofilling procedure afterward to correct small irregularities or asymmetry. The advantages of the TMG flap such as short harvesting time, inconspicuous donor site, and the possibility of having a natural breast shape make it our first choice to treat capsular contracture after breast reconstruction and augmentation.

    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.

    Management of pressure sores poses a significant reconstructive challenge for plastic surgeons. Currently, there is no consensus on whether musculocutaneous, fasciocutaneous, or perforator-based flaps provide superior results for treating pressure sores. The following databases were searched: Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, LILACS (January of 1950 to November of 2010), MEDLINE (January of 1950 to November of 2010), and EMBASE (January of 1980 to November of 2010). Only articles reporting on the use of musculocutaneous, fasciocutaneous, and perforator-based flaps were included. The primary study outcomes were complication and recurrence rates. Fifty-five articles were included in the final analysis (kappa = 0.78). From this total, 28 were categorized as pertaining to musculocutaneous flaps, 13 studied fasciocutaneous flaps, and 14 evaluated perforator-based flaps. The authors' review revealed recurrence and complication rates of 8.9 and 18.6 percent, respectively, following reconstruction with musculocutaneous flaps, 11.2 and 11.7 percent following reconstruction with fasciocutaneous flaps, and 5.6 and 19.6 percent following reconstruction with perforator-based flaps. Overall, statistical analysis revealed no significant difference in complication or recurrence rates among these three techniques. The authors' review revealed that there was no statistically significant difference with regard to recurrence or complication rates among musculocutaneous, fasciocutaneous, or perforator-based flaps. This suggests that surgeons performing such reconstructive procedures may choose to consider the advantages of a specific approach rather than the complication and recurrence rates. Therapeutic, IV.

  3. A variation of Musculocutaneous nerve without piercing the coracobrachialis muscle while communicating to the median nerve: A case report and literature review

    Full Text Available Introduction: Anatomical variations of the peripheral nervous system may have not any clinical signs and symptoms. One of these variations belongs to the Musculocutaneous nerve. However, a good knowledge of nerve pathways and their variations is very important for surgeons in post-traumatic evaluations, exploratory interventions, and/or administration of neuromuscular blocks in axillary region in order to surgical therapies. Presentation of case: This report describes a case of variation of the musculocutaneous nerve which was observed in an old Iranian male cadaver during routine educational dissection (Fig. 1. Discussion and Conclusion: Anatomically, in the axilla region, the Musculocutaneous nerve is originated of the lateral cord of brachial plexus, then, by piercing the coracobrachialis muscle arrives enters to anterior compartment of the arm. But, in the present report, we observed that the Musculocutaneous nerve without piercing the coracobrachialis muscle has arrived in the left arm, then communicated to the Median nerve. To exploratory interventions of the arms for peripheral nerve repair and surgical therapies, a good knowledge of nerve pathways helps to surgeons for preventing possible mistakes during surgery.

    Full Text Available Background: Structural details of vertebrate extraocular muscles (EOMs have shown an anatomically and functionally distinct laminar organization into an outer orbital (OL and an inner global layer (GL. Since hyperthyroidism alters tissue oxidative metabolism through mitochondrial enzymes, it is expected that structural/mitochondrial changes may be seen in hyperthyroid EOMs. We investigated the alterations in the laminar organization and mitochondrial changes in hyperthyroid mouse EOMs. Methods: Hyperthyroidism was induced in C57BL/6 mice and fresh rectus muscles were obtained to identify functional mitochondria using MitoTracker® Green and confocal microscopy; frozen sections from rectus muscles were stained with anti-rabbit Troponin T (selectively present in the OL to demonstrate changes in the OL and GL of the EOMs. Ultrastructural features of EOMs were studied using transmission electron microscopy (TEM.Results: Of all 4 rectus EOMs studied, the maximum change was seen in the inferior rectus muscle (IR followed by medial rectus (MR. Myofiber cross sectional area measurements and Troponin T staining in the control IR EOMs demonstrated a smaller OL (113.2 ± 3.66 μm2 and higher density staining with Troponin T (90% and a larger GL (411 ± 13.84 μm2 with low intensity staining (10%, while hyperthyroidism resulted in an increased OL (205.9 ± 5.3 μm2 and decreased GL (271.7 ± 7.5 μm2 p=0.001. Confocal microscopy demonstrated an intense staining especially in the outer rims in the hyperthyroid IR which was confirmed by TEM showing structural alterations in the mitochondria and a subsarcolemmal migration. Conclusions: The outer, thinner, orbital layer (OL of the mouse EOM contains smaller diameter myofibers and fewer mitochondria while the inner, larger global layer (GL contains larger diameter myofibers and larger density of mitochondria. Hyperthyroidism results in a significant alteration in the laminar organization and mitochondria of

    The transverse musculocutaneous gracilis (TMG) flap has become a common solution for breast reconstruction. However, the safe skin paddle limits are not yet understood. In this study, we attempted to address this issue based on our experiences with inferior and posterior skin paddle extension. Forty-four breast reconstructions with TMG flaps performed between November 2010 and January 2014 were analyzed retrospectively. For the first 20 cases, the flap skin paddle was extended 3 cm posteriorly to the middle thigh (group 1). For the next 20 flaps (group 2), the posterior tip was limited to this line, whereas more fat was recruited inferiorly. In the four cases of group 3, the skin flap was extended posteriorly with a second vascular pedicle from the profunda artery perforator (PAP) flap. The weights and the dimensions of the flaps, operating durations, and postoperative complications of the entire series were analyzed. Groups 1 and 2 were statistically compared. Flap complications were statistically more frequent in group 1 compared with group 2 (45 vs. 0%, P = 0.0012); 40% posterior flap tip necrosis was observed in group 1. Conversely, donor site complications were statistically more frequent in group 2 than in group 1 (40 vs. 5%, P = 0.019) with 35% inner thigh dehiscence. In the TMG with extended PAP flap group, the operating duration was 77 min longer compared with the rest of the series with no donor site complications. In one case, limited necrosis occurred at the anterior skin tip. Harvesting the posterior portion of the TMG up to the middle of the posterior thigh may lead to partial flap necrosis. Extending subcutaneous fat removal under the inferior skin incision may increase the risk of donor site complications. Adding a second vascular pedicle from the PAP flap may improve posterior TMG tip perfusion at the expense of a longer operation. © 2015 Wiley Periodicals, Inc.

    The transverse musculocutaneous gracilis (TMG) flap has received little attention in the literature as a valuable alternative source of donor tissue in the setting of breast reconstruction. The authors give an in-depth review of their experience with breast reconstruction using the TMG flap. A retrospective review of 111 patients treated with a TMG flap for breast reconstruction in an immediate or a delayed setting between August of 2002 and July of 2007 was undertaken. Of these, 26 patients underwent bilateral reconstruction and 68 underwent unilateral reconstruction, and 17 patients underwent reconstruction unilaterally with a double TMG flap. Patient age ranged between 24 and 65 years (mean, 37 years). Twelve patients had to be taken back to the operating room because of flap-related problems and nine patients underwent successful revision microsurgically, resulting in three complete flap losses in a series of 111 patients with 154 transplanted TMG flaps. Partial flap loss was encountered in two patients, whereas fat tissue necrosis was managed conservatively in six patients. Donor-site morbidity was an advantage of this flap, with a concealed scar and minimal contour irregularities of the thigh, even in unilateral harvest. Complications included delayed wound healing (n = 10), hematoma (n = 5), and transient sensory deficit over the posterior thigh (n = 49). The TMG flap is more than an alternative to the deep inferior epigastric perforator (DIEP) flap in microsurgical breast reconstruction in selected patients. In certain indications, such as bilateral reconstructions, it possibly surpasses the DIEP flap because of a better concealed donor scar and easier harvest.

    Full Text Available Abstract Background and goal of study: After laparoscopic cholecystectomy, patients have moderate pain in the early postoperative period. Some studies shown beneficial effects of subcostal transversus abdominis plane block on reducing this pain. Our goal was to investigate influence of subcostal transversus abdominis plane block on postoperative pain scores and opioid consumption. Materials and methods: We have randomized 76 patients undergoing laparoscopic cholecystectomy to receive either subcostal transversus abdominis plane block (n = 38 or standard postoperative analgesia (n = 38. First group received bilateral ultrasound guided subcostal transversus abdominis plane block with 20 mL of 0.33% bupivacaine per side before operation and tramadol 1 mg.kg−1 IV for pain breakthrough (≥6. Second group received after operation tramadol 1 mg.kg−1/6 h as standard hospital analgesia protocol. Both groups received acetaminophen 1 g/8 h IV and metamizole 2.5 g/12 h. Pain at rest was recorded for each patient using NR scale (0–10 in period of 10 min, 30 min, 2 h, 4 h, 8 h, 12 h and 16 h after the surgery. Results and discussion: We obtained no difference between groups according age, weight, intraoperative fentanyl consumption and duration of surgery. Subcostal transversus abdominis plane block significantly reduced postoperative pain scores compared to standard analgesia in all periods after surgery. Tramadol consumption was significantly lower in the subcostal transversus abdominis plane (24.29 ± 47.54 g than in the standard analgesia group (270.2 ± 81.9 g (p = 0.000. Conclusion: Our results show that subcostal transversus abdominis plane block can provide superior postoperative analgesia and reduction in opioid requirements after laparoscopic cholecystectomy.

    The phrenic nerve can be transferred to the musculocutaneous nerve in patients with traumatic brachial plexus palsy in order to recover biceps strength, but the results are controversial. There is also a concern about pulmonary function after phrenic nerve transection. In this paper, we performed a qualitative systematic review, evaluating outcomes after this procedure. A systematic review of published studies was undertaken in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement. Data were extracted from the selected papers and related to: publication, study design, outcome (biceps strength in accordance with BMRC and pulmonary function) and population. Study quality was assessed using the "strengthening the reporting of observational studies in epidemiology" (STROBE) standard or the CONSORT checklist, depending on the study design. Seven studies were selected for this systematic review after applying inclusion and exclusion criteria. One hundred twenty-four patients completed follow-up, and most of them were graded M3 or M4 (70.1 %) for biceps strength at the final evaluation. Pulmonary function was analyzed in five studies. It was not possible to perform a statistical comparison between studies because the authors used different parameters for evaluation. Most of the patients exhibited a decrease in pulmonary function tests immediately after surgery, with recovery in the following months. Study quality was determined using STROBE in six articles, and the global score varied from 8 to 21. Phrenic nerve transfer to the musculocutaneous nerve can recover biceps strength ≥M3 (BMRC) in most patients with traumatic brachial plexus injury. Early postoperative findings revealed that the development of pulmonary symptoms is rare, but it cannot be concluded that the procedure is safe because there is no study evaluating pulmonary function in old age.

    Full Text Available Purpose. Transversus abdominis plane (TAP blocks have been shown to reduce pain and opioid requirements after abdominal surgery. The aim of the present case series was to demonstrate the use of TAP catheter injections of bupivacaine after major abdominal surgery. Methods. Fifteen patients scheduled for open colonic resection surgery were included. After induction of anesthesia, bilateral TAP catheters were placed, and all patients received a bolus dose of 20 mL bupivacaine 2.5 mg/mL with epinephrine 5 μg/mL through each catheter. Additional bolus doses were injected bilaterally 12, 24, and 36 hrs after the first injections. Supplemental pain treatment consisted of paracetamol, ibuprofen, and gabapentin. Intravenous morphine was used as rescue analgesic. Postoperative pain was rated on a numeric rating scale (NRS, 0–10 at regular predefined intervals after surgery, and consumption of intravenous morphine was recorded. Results. The TAP catheters were placed without any technical difficulties. NRS scores were ≤3 at rest and ≤5 during cough at 4, 8, 12, 18, 24, and 36 hrs after surgery. Cumulative consumption of intravenous morphine was 28 (23–48 mg (median, IQR within the first 48 postoperative hours. Conclusion. TAP catheter bolus injections can be used to prolong analgesia after major abdominal surgery.

  11. Transient Femoral Nerve Palsy Complicating “Blind” Transversus Abdominis Plane Block

    Directory of Open Access Journals (Sweden)

    Dimitrios K. Manatakis

    2013-01-01

    Full Text Available We present two cases of patients who reported quadriceps femoris weakness and hypoesthesia over the anterior thigh after an inguinal hernia repair under transversus abdominis plane (TAP block. Transient femoral nerve palsy is the result of local anesthetic incorrectly injected between transversus abdominis muscle and transversalis fascia and pooling around the femoral nerve. Although it is a minor and self-limiting complication, it requires overnight hospital stay and observation of the patients. Performing the block under ultrasound guidance and injecting the least volume of local anesthetic required are ways of minimizing its incidence.

    Incisional hernia (IH) can be attributed to multiple factors. The presence of a parastomal hernia has shown to be a risk factor for IH after midline laparotomy. Our hypothesis is that this increased risk of IH may be caused by changes in biomechanical forces, such as midline shift to the contralateral side of the colostomy owing to decreased restraining forces at the site of the colostomy, and left abdominal rectus muscle (ARM) atrophy owing to intercostal nerve damage. Patients were selected if they underwent end-colostomy via open operation between 2004 and 2011. Patients were eligible if computed tomography (CT) had been performed postoperatively. If available, preoperative CTs were collected for case-control analyses. Midline shift was measured using V-scope application in the I-space, a CAVE-like virtual reality system. For the ARM atrophy hypothesis, measurements of ARM were performed at the level of colostomy, and 3 and 8 cm cranial and caudal of the colostomy. Postoperative CT were available for 77 patients; of these patients, 30 also had a preoperative CT. Median follow-up was 19 months. A mean shift to the right side was identified after preoperative and postoperative comparison; from -1.3 ± 4.6 to 2.1 ± 9.3 (P = .043). Furthermore, during rectus muscle measurements, a thinner left ARM was observed below the level of colostomy. Creation of a colostomy alters the abdominal wall. Atrophy of the left ARM was seen caudal to the level of the colostomy, and a midline shift to the right side was evident on CT. These changes may explain the increased rate of IH after colostomy creation. Copyright © 2014 Mosby, Inc. All rights reserved.

    Dissociated strabismus complex (DSC) is an enigmatic form of strabismus that includes dissociated vertical deviation (DVD) and dissociated horizontal deviation (DHD). We employed magnetic resonance imaging (MRI) to evaluate the extraocular muscles in DSC. We studied 5 patients with DSC and mean age of 25 years (range, 12-42 years), and 15 age-matched, orthotropic control subjects. All patients had DVD; 4 also had DHD. We employed high-resolution, surface coil MRI with thin, 2 mm slices and central target fixation. Volumes of the rectus and superior oblique muscles in the region 12 mm posterior to 4 mm anterior to the globe-optic nerve junction were measured in quasi-coronal planes in central gaze. Patients with DSC had no structural abnormalities of rectus muscles or rectus pulleys or the superior oblique muscle but exhibited modest, statistically significant increased volume of all rectus muscles ranging from 20% for medial rectus to 9% for lateral rectus (P muscles. DSC is associated with generalized rectus extraocular muscle hypertrophy in the absence of other orbital abnormalities.

    Breast reconstruction has become standard of care for female patients with breast cancer. The transverse rectus abdominis musculo-cutaneous flap (TRAMf) is the most common method of immediate or delayed autologous breast reconstruction following mastectomy. We share our experience with modified, double back cut of post-mastectomy skin in delayed pedicled TRAMf breast reconstruction, resulting in fish-shaped skin paddle. This sort of back cut is a simple, reliable way to obtain a natural, esthetically pleasant breast mound with inconspicuous hidden scars.

    Full Text Available Infected pseudoaneurysm of the femoral artery represents a devastating complication of intravenous drug abuse, especially in the event of rupture. Operative strategy depends upon the extent of arterial injury and the coexistence of infection or sepsis. Options range from simple common femoral artery (CFA ligation to complex arterial reconstruction with autologous grafts (arterial, venous, or homografts. We report herein the management of a 29-year-old male patient who was urgently admitted with a ruptured pseudoaneurysm of the right CFA, extending well above the inguinal ligament. Multidisciplinary approach with multiple arterial reconstructions and subsequent coverage of the tissue defect with a rectus abdominis musculocutaneous flap transposition was performed.

    During the past 2 decades, the introduction of functional endoscopic sinus surgery (FESS) has dramatically improved the treatment of sinus disorders. However, a variety of orbital complications have been reported, including optic nerve damage, hemorrhage, infection, compromise of the lacrimal drainage apparatus, and strabismus. At least 10 cases have reported damage to the medial rectus muscle. (1-8) Treatment options for such patients have been limited, especially because most are adults at risk for anterior segment ischemia after transposition of vertical rectus muscles. We describe 2 patients whose medial rectus myectomies were repaired by using nonabsorbable "hang-back" sutures in combination with a botulinum toxin (Botox) injection of the antagonist lateral rectus muscle. Good primary position alignment was achieved in both patients, and one patient was able to regain binocular function. We recommend this surgical approach, especially in patients at increased risk for anterior segment ischemia.

    Unilateral treatment with sustained release IGF-1 to one medial rectus muscle in infant monkeys was performed to test the hypothesis that strabismus would develop as a result of changes in extraocular muscles during the critical period of development of binocularity. Sustained release IGF-1 pellets were implanted unilaterally on one medial rectus muscle in normal infant monkeys during the first 2 weeks of life. Eye position was monitored using standard photographic methods. After 3 months of treatment, myofiber and neuromuscular size, myosin composition, and innervation density were quantified in all rectus muscles and compared to those in age-matched controls. Sustained unilateral IGF-1 treatments resulted in strabismus for all treated subjects; 3 of the 4 subjects had a clinically significant strabismus of more than 10°. Both the treated medial rectus and the untreated ipsilateral antagonist lateral rectus muscles had significantly larger myofibers. No adaptation in myofiber size occurred in the contralateral functionally yoked lateral rectus or in myosin composition, neuromuscular junction size, or nerve density. Sustained unilateral IGF-1 treatment to extraocular muscles during the sensitive period of development of orthotropic eye alignment and binocularity was sufficient to disturb ocular motor development, resulting in strabismus in infant monkeys. This could be due to altering fusion of gaze during the early sensitive period. Serial measurements of eye alignment suggested the IGF-1-treated infants received insufficient coordinated binocular experience, preventing the establishment of normal eye alignment. Our results uniquely suggest that abnormal signaling by the extraocular muscles may be a cause of strabismus.

    Full Text Available Abstract Introduction A rectus sheath haematoma is a rare condition that arises from the accumulation of blood within the rectus sheath from either muscular tear or rupture of the epigastric vessels. It is a known complication of either blunt abdominal trauma, anticoagulation therapy or the repetitive contraction of the rectus muscle such as paroxysms of coughing. It remains an uncommon and elusive entity and is often clinically misdiagnosed. Case presentation An 80-year-old British man with a known aortic aneurysm was admitted with sudden onset of right iliac fossa pain. The patient was hemodynamically stable and underwent a computed tomography scan which revealed an intact aorta and an acute rectus sheath hematoma. Conclusion To the best of our knowledge, no case has previously been reported involving the diagnostic challenge of a rectus sheath hematoma in a patient with a known aortic aneurysm. Here we discuss the symptoms and signs of a rectus sheath hematoma, as well as the radiological modalities that could be utilized to reach the diagnosis.

    PURPOSE To study the ultrastructure of the medial rectus in patients with intermittent exotropia at different ages.PATIENTS AND METHODS The medial recti were harvested surgically from 20 patients with intermittent exotropia. Patients were divided into adolescent (age18 years, n=10). The normal control group included five patients without strabismus and undergoing eye enucleation. Hematoxylin and eosin staining and transmission electron microscopy were used to visualize the medial recti. Western blot was used to determine the levels of myosin and actin.RESULTS Varying fiber thickness, atrophy, and misalignment of the medial recti were visualized under optical microscope in patients with exotropia. Electron microscopy revealed sarcomere destruction, myofilament disintegration, unclear dark and light bands, collagen proliferation, and fibrosis. The adolescent group manifested significantly higher levels of myosin and actin than the adult group (Pstronger contraction of the medial recti compared with older patients. Our findings suggest that childhood was the appropriate time for surgery as the benefit of the intervention was better than in adulthood.

    Effective postoperative analgesia after cesarean delivery enhances early recovery, ambulation, and breastfeeding. In a previous study, we established the effectiveness of the quadratus lumborum block in providing pain relief after cesarean delivery compared with patient-controlled analgesia (morphine). In the current study, we hypothesized that this method would be equal to or better than the transversus abdominis plane block with regard to pain relief and its duration of action after cesarean delivery. Between April 2015 and August 2015, we randomized 76 patients scheduled for elective cesarean delivery under spinal anesthesia to receive the quadratus lumborum block or the transversus abdominis plane block for postoperative pain relief. This trial was registered prospectively (NCT 02489851) [corrected]. Patients in the quadratus lumborum block group used significantly less morphine than the transversus abdominis plane block group (P consumption and demands than transversus abdominis plane blocks after cesarean section. This effect was observed up to 48 hours postoperatively.

    Full Text Available OBJECTIVE: To investigate the feasibility of using free gracilis muscle transfer along with the brachialis muscle branch of the musculocutaneous nerve to restore finger and thumb flexion in lower trunk brachial plexus injury according to an anatomical study and a case report. METHODS: Thirty formalin-fixed upper extremities from 15 adult cadavers were used in this study. The distance from the point at which the brachialis muscle branch of the musculocutaneous nerve originates to the midpoint of the humeral condylar was measured, as well as the length, diameter, course and branch type of the brachialis muscle branch of the musculocutaneous nerve. An 18-year-old male who sustained an injury to the left brachial plexus underwent free gracilis transfer using the brachialis muscle branch of the musculocutaneous nerve as the donor nerve to restore finger and thumb flexion. Elbow flexion power and hand grip strength were recorded according to British Medical Research Council standards. Postoperative measures of the total active motion of the fingers were obtained monthly. RESULTS: The mean length and diameter of the brachialis muscle branch of the musculocutaneous nerve were 52.66±6.45 and 1.39±0.09 mm, respectively, and three branching types were observed. For the patient, the first gracilis contraction occurred during the 4th month. A noticeable improvement was observed in digit flexion one year later; the muscle power was M4, and the total active motion of the fingers was 209°. CONCLUSIONS: Repairing injury to the lower trunk of the brachial plexus by transferring the brachialis muscle branch of the musculocutaneous nerve to the anterior branch of the obturator nerve using a tension-free direct suture is technically feasible, and the clinical outcome was satisfactory in a single surgical patient.

    Three patients with avulsed C5, C6, and C7 roots and two patients with avulsed C5 and C6 roots after trauma of the brachial plexus, were treated by neurotization of the biceps using nerve fibers derived from the ulnar nerve and obtained by end-to-side neurorraphy between the ulnar and musculocutaneous nerves. The age of patients ranged from 19 to 45. The interval between the accident and surgery was 2 to 13 months. Return of biceps contraction was observed 4 to 6 months after surgery. Four patients recovered grade 4 elbow flexion. One 45-year-old patient did not obtain any biceps contraction after 9 months.

    Lumbar paraspinal muscles play an important role in providing both mobility and stability during dynamic tasks. Among paraspinal muscles, transverse abdominis and lumbar multifidus have been of particular interest as active stabilizers of the lumbar spine. These muscles may become dysfunctional in chronic low back pain (CLBP). Low back injury can result in muscle inhibition and control loss that cannot recover spontaneously, and specific exercises are required to stimulate their recovery. The purpose of this study was to test the reliability of ultrasonography to measure muscle dimensions and to present a reliable method for measuring transverse abdominis and lumbar multifidus as stabilizing muscles of the lumbar spine. Fifteen healthy participants (18-55 year olds) were evaluated by a radiologist using ultrasonography (ES500) with two probes (50mm linear 7.5 MHZ and 70 mm curvilinear 3.5 MHz). The muscle thickness of transverse abdominis and the anterior-posterior diameter and cross sectional area of the LMF were measured. To determine within and between days reliabilities, second and third measurements were repeated with half an hour and one week intervals, respectively. Intraclass correlation coefficient for left and right showed good to high reliability for the cross sectional area of lumbar multifidi (0.74 and 0.88, respectively) as well as the anterior-posterior dimensions of lumbar multifidi (0.89 and 0.91, respectively) and transverse abdomini thickness (0.73 and 0.85, respectively). Rehabilitative ultrasonography is a reliable and non-invasive instrument to measure muscle thickness. The method used in this study is a reliable way to measure lumbar stabilizing muscles

    The incidence of fascial dehiscence and incisional hernia after two methods for abdominal wound closure (rectus sheath relaxation incisions and conventional mass closure) was studied in a randomized prospective clinical trial in a consecutive series of 100 patients undergoing midline laparotomy for peritonitis. The two groups were well matched for etiologies of peritonitis, the surgical procedures performed, and the presence of known risk factors for fascial dehiscence. Fifty patients each were randomized either to the conventional continuous mass closure procedure or the rectus sheath relaxation incision technique (designed to increase wound elasticity and decrease tension in the suture line) using identical polypropylene sutures. The incidence of postoperative complications such as duration of ileus, chest infection, and wound infection were not statistically different between the two groups. The intensity of postoperative pain in the rectus sheath relaxation incision group was significantly less. The incidence of wound hematoma was significantly increased in the rectus sheath relaxation incision group. The incidences of fascial dehiscence (16% vs,28%; p cases of peritonitis using the rectus sheath relaxation technique is safe and less painful, provides increased wound elasticity and decreased tension on the suture line, and significantly decreases the incidence of wound dehiscence.

    2009-12-01

    Superior oblique palsy is accompanied in most cases by overaction of the muscle's ipsilateral antagonist, the inferior oblique muscle. Overaction and contracture of the ipsilateral superior rectus muscle in patients with unilateral fourth (trochlear) nerve palsy is seldom discussed in the literature. The purpose of this study is to evaluate the frequency of superior rectus muscle overaction/contracture syndrome in patients with unilateral trochlear nerve palsy. The records of 198 patients with unilateral trochlear nerve palsy examined by the authors between July 1987 and July 2008 were reviewed retrospectively. All patients underwent complete eye examination with measurement of the deviation in the 9 positions of gaze and with the head tilted to both sides in all cooperative patients. Selection criteria for superior rectus muscle overaction/contracture syndrome in these patients were as follows: vertical deviation of 15(Delta) or larger in primary position, equal or larger hypertropia with the ipsilateral forced tilt test than with the eyes looking straight ahead, more than 5(Delta) hypertropia of the affected eye in horizontal gaze to the same side, hypertropia in all upgazes, and overaction of the contralateral superior oblique muscle. Of 198 patients, 33 (16.6%) met the selection criteria for superior rectus muscle overaction/contracture syndrome. Superior rectus muscle overaction/contracture syndrome frequently occurs in unilateral superior oblique palsy.

    It is suggested that activation of the transverse abdominis muscle has a stabilizing effect on the lumbar spine by raising intra-abdominal pressure without added disc compression. However, its feedforward activity has remained a controversial issue. In addition, research regarding bilateral activation of trunk muscles during a unilateral arm movement is limited. The aim of this study was to evaluate bilateral anticipatory activity of trunk muscles during unilateral arm flexion. Eighteen healthy subjects (aged 25 ± 3.96 years) participated in this study and performed 10 trials of rapid arm flexion in response to a visual stimulus. The electromyographic activity of the right anterior deltoid (AD) and bilateral trunk muscles including the transverse abdominis/internal oblique (TA/IO), superficial lumbar multifidus (SLM) and lumbar erector spine (LES) was recorded. The onset latency and anticipatory activity of the recorded trunk muscles were calculated. The first muscle activated in anticipation of the right arm flexion was the left TA/IO. The right TA/IO activated significantly later than all other trunk muscles (P 0.05). Healthy subjects showed no bilateral anticipatory co-activation of TA/IO in unilateral arm elevation. Further investigations are required to delineate normal muscle activation pattern in healthy subjects prior to prescribing bilateral activation training of transverse abdominis for subjects with chronic low back pain.

    Transversus abdominis plane block is a regional anaesthesia technique that has proven to be effective for postoperative pain reduction in different abdominal surgical procedures. This study evaluated its efficacy on post laparoscopic hysterectomy pain intensity and analgesic consumption. Randomized controlled trial which included 40 patients scheduled for laparoscopic hysterectomy, enrolled in 2 groups: transversus abdominis plane block+systemic analgesia (Group 1; n=20), versus systemic analgesia (Group 2; n=20). Opioid consumption within the first 24 postoperative hours, pain intensity scores at 60min, 2, 8 and 24h after surgery, adverse events related to systemic analgesia and time to hospital discharge were evaluated and registered. We found no differences between both groups in opioid consumption (10mg vs. 7mg; P=.2) and pain scores (NVS) within the first 24 postoperative hours, at 60min (3 vs. 5; P=.65), 120min (0 vs. 2; P=.15), 8 and 24h (0 vs. 0; P>.50) for the last 2 points in time analysed. Adverse events related to medication and time to hospital discharge showed similar results. Adding a transversus abdominis plane block technique to opioid PCA does not seem to improve postoperative pain management in laparoscopic hysterectomy. Patient preparation time and costs could be incremented and complications (although rare) related to the technique could appear.

    Surgical treatment of perineal pressure sores could be done with various fascio-cutaneous or musculo-cutaneous flaps, which provide cover and filling of most of pressure sores after spinal cord injuries. In rare cases, classical solutions are overtaken, then it is necessary to use more complex techniques. We report a case of a made-to-measure lower limb flap for coverage of confluent perineal pressure sores. A 49-year-old paraplegic patient developed multiple pressure sores on left and right ischial tuberosity, inferior pubic bone and bilateral trochanters with hips dislocation. Surgical treatment involved a whole right thigh flap to cover and fill right side lesions, associated to a posterior right leg musculo-cutaneous island flap to cover and fill the left trochanteric pressure sore. The surgical procedure lasted 6.5 hours and required massive blood transfusion. Antibiotics were adapted to bacteriological samples. There were no postoperative complications; complete wound healing occurred after three weeks. A lower limb sacrifice for coverage of a giant perineal pressure sores is an extreme surgical solution, reserved to patients understanding the issues of this last chance procedure. A good knowledge of vascular anatomy is an essential prerequisite, and allows to shape made-to-measure flaps. The success of such a procedure is closely linked to the collaboration with the rehabilitation team (appropriate therapeutic education concerning transfers and positioning).

    Most published cases of rectus muscle flap tear have been associated with orbital trauma of various degrees of severity. When they accompany an orbital fracture, however, it is difficult to determine whether the flap tear is merely an incidental additional finding or a major contributing cause of the resulting restriction. How to treat the flap itself remains an open question. We report a 24-year-old man with an inferior rectus muscle flap tear caused by direct laceration of the muscle. The major finding was a "reverse leash" vertical restriction. Discarding the flap instead of reattaching it did not prevent a successful result. Our case supports the proposition that rectus muscle flap tear can be a restriction-producing entity. Copyright © 2012 American Association for Pediatric Ophthalmology and Strabismus.

    OBJECTIVE Neonatal brachial plexus palsy (NBPP) continues to be a problematic occurrence impacting approximately 1.5 per 1000 live births in the United States, with 10%-40% of these infants experiencing permanent disability. These children lose elbow flexion, and one surgical option for recovering it is the Oberlin transfer. Published data support the use of the ulnar nerve fascicle that innervates the flexor carpi ulnaris as the donor nerve in adults, but no analogous published data exist for infants. This study investigated the association of ulnar nerve fascicle choice with functional elbow flexion outcome in NBPP. METHODS The authors conducted a retrospective study of 13 cases in which infants underwent ulnar to musculocutaneous nerve transfer for NBPP at a single institution. They collected data on patient demographics, clinical characteristics, active range of motion (AROM), and intraoperative neuromonitoring (IONM) (using 4 ulnar nerve index muscles). Standard statistical analysis compared pre- and postoperative motor function improvement between specific fascicle transfer (1-2 muscles for either wrist flexion or hand intrinsics) and nonspecific fascicle transfer (> 2 muscles for wrist flexion and hand intrinsics) groups. RESULTS The patients' average age at initial clinic visit was 2.9 months, and their average age at surgical intervention was 7.4 months. All NBPPs were unilateral; the majority of patients were female (61%), were Caucasian (69%), had right-sided NBPP (61%), and had Narakas grade I or II injuries (54%). IONM recordings for the fascicular dissection revealed a donor fascicle with nonspecific innervation in 6 (46%) infants and specific innervation in the remaining 7 (54%) patients. At 6-month follow-up, the AROM improvement in elbow flexion in adduction was 38° in the specific fascicle transfer group versus 36° in the nonspecific fascicle transfer group, with no statistically significant difference (p = 0.93). CONCLUSIONS Both specific and

    Full Text Available Abstract Background and objectives: A transversus abdominis plane block is a peripheral block method that has been used successfully for pain relief after total abdominal hysterectomy. However, the effects of the combination of the transversus abdominis plane block and general anesthesia on analgesic and anesthetic requirements remain unclear. This randomized placebo-controlled study is aimed to evaluate the effects of transversus abdominis plane block on analgesic and anesthetic consumption during total abdominal hysterectomy under general anesthesia. Methods: Sixty-six women undergoing total abdominal hysterectomy were randomized into two groups to receive general anesthesia alone (control group or with transversus abdominis plane block using 20 mL of 0.25% bupivacaine (transversus abdominis plane group. Intraoperative remifentanil and sevoflurane consumption were recorded. We also evaluated the postoperative pain, nausea, quality of recovery scores and rescue analgesic requirement during postoperative 24 hours. Results: The total remifentanil and sevoflurane consumption is significantly lower in transversus abdominis plane group; respectively mean (SD 0.130 (0.25 vs. 0.094 (0.02 mcg.kg-1.min-1; p < 0.01 and 0.295 (0.05 vs. 0.243 (0.06 mL.min-1; p < 0.01. In the postoperative period, pain scores were significantly reduced in transversus abdominis plane group soon after surgery; median (range 6 (2-10 vs. 3 (0-5; p < 0.001, at 2 h (5 [3-9] vs. 2.5 [0-6]; p < 0.001, at 6 h (4 [2-7] vs. 3[0-6], p < 0.001, at 12 h (3.5 [1-6] vs. 2 [1-5]; p = 0.003. The patients in the transversus abdominis plane group had significantly higher QoR-40 scores 190.5 (175-197 vs. 176.5 (141-187; p < 0.001. Conclusion: Combining transversus abdominis plane block with general anesthesia can provide reduced opioid and anesthetic consumption and can improve postoperative pain and quality of recovery scores in patients undergoing total abdominal hysterectomy.

  5. Correlation between the Limbus-Insertion Distance of the Lateral Rectus Muscle and Lateral Rectus Recession Surgery in Intermittent Exotropia.

    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.

    Substantial fluctuations in body weight can result in diastasis recti and weakening of the connections between the lateral abdominal muscles and the rectus sheath. The authors sought to determine the postural and psychological effects of abdominoplasty with vertical rectus plication. Forty women with substantial back and lumbar pain owing to abdominal lipodystrophy were evaluated in a prospective study. Preoperatively and 6 months postoperatively, patients underwent bidirectional radiography of the thoracic and lumbar regions. A visual analog scale (VAS), the Beck Depression Inventory (BDI), and the Nottingham Health Profile (NHP) were applied to assess physical, psychological, and quality-of-life changes following surgery. Significant improvements in posture, assessed in terms of lumbar lordosis, thoracic kyphosis, and the lumbosacral angle, were observed 6 months after abdominoplasty with rectus plication. Results of the VAS and BDI indicated significant improvements in pain and quality of life, respectively. Results of the NHP indicated significant postoperative improvements in fatigue, pain, and sleep. Abdominoplasty with rectus plication improves posture by tightening the thoracolumbar fascia. In selected patients, abdominoplasty can reduce back and lumbar pain, thereby improving quality of life. © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

    Full Text Available Background: A major challenge in the postoperative period is pain management which, if not adequately controlled, may contribute to patient discomfort and decreased patient satisfaction, and possibly increased morbidity and mortality. Both Thoracic paravertebral block and oblique subcostal transversus abdominis plane block can be used as analgesic techniques for abdominal surgeries. Our aim in this research was comparison of cumulative 24-h post-operative morphine consumption between ultrasound-guided oblique subcostal transversus abdominis plane block and ultrasound-guided thoracic paravertebral block in patients who underwent an open cholecystectomy under general anesthesia. Patients and methods: This study was performed on 46 patients who underwent open cholecystectomy under general anesthesia. All patients were randomly allocated alternatively to one of two equal groups to either undergo ultrasound-guided unilateral oblique subcostal transversus abdominis plane block Group (I or to undergo ultrasound-guided unilateral thoracic paravertebral block Group (II. Both groups were subjected to a similar analgesic regimen in the immediate post-operative period that involved intravenous patient-controlled morphine analgesia which was used in both groups. Results: The total morphine consumption in the first postoperative 24 h was lower in thoracic paravertebral block Group (II (9.9 mg in thoracic paravertebral block group vs. 15.4 mg in oblique subcostal transversus abdominis plane block Group (I with p < 0.001. The mean time of first request of analgesia in Group (I was 248.7 min compared to 432.1 for Group (II with p < 0.001. Conclusions: Both ultrasound-guided oblique subcostal transversus abdominis plain block and single injection ultrasound guided thoracic paravertebral block are effective analgesic techniques for upper abdominal surgeries and reduces postoperative opioid requirements. However, thoracic paravertebral block is more

    A transversus abdominis plane block is a peripheral block method that has been used successfully for pain relief after total abdominal hysterectomy. However, the effects of the combination of the transversus abdominis plane block and general anesthesia on analgesic and anesthetic requirements remain unclear. This randomized placebo-controlled study is aimed to evaluate the effects of transversus abdominis plane block on analgesic and anesthetic consumption during total abdominal hysterectomy under general anesthesia. Sixty-six women undergoing total abdominal hysterectomy were randomized into two groups to receive general anesthesia alone (control group) or with transversus abdominis plane block using 20mL of 0.25% bupivacaine (transversus abdominis plane group). Intraoperative remifentanil and sevoflurane consumption were recorded. We also evaluated the postoperative pain, nausea, quality of recovery scores and rescue analgesic requirement during postoperative 24hours. The total remifentanil and sevoflurane consumption is significantly lower in transversus abdominis plane group; respectively mean (SD) 0.130 (0.25) vs. 0.094 (0.02) mcg.kg -1 .min -1 ; pplane group soon after surgery; median (range) 6 (2-10) vs. 3 (0-5); pplane group had significantly higher QoR-40 scores 190.5 (175-197) vs. 176.5 (141-187); pplane block with general anesthesia can provide reduced opioid and anesthetic consumption and can improve postoperative pain and quality of recovery scores in patients undergoing total abdominal hysterectomy.

    Since 1907 a variety of muscle transposition procedures for the treatment of abducens nerve palsy has been established internationally. Full tendon transposition of the vertical rectus muscle was initially described by O'Connor 1935 and then augmented by Foster 1997 with addition of posterior fixation sutures on the vertical rectus muscle. Full tendon transposition augmented by Foster belongs to the group of the most powerful surgical techniques to improve the abduction. Purpose of this study was to evaluate the results of full tendon vertical rectus transposition augmented with lateral fixation suture for patients with abducens nerve palsy. Full tendon transpositions of vertical rectus muscles augmented with posterior fixation suture was performed in 2014 on five patients with abducens nerve palsy. Two of the patients received Botox injections in the medial rectus muscle: one of them three months after the surgery and another during the surgery. One of the patients had a combined surgery of the horizontal muscles one year before. On three of the patients, who received a pure transposition surgery, the preoperative deviation at the distance (mean: + 56.6 pd; range: + 40 to + 80 pd) was reduced by a mean of 39.6 pd (range 34 to 50 pd), the abduction was improved by a mean of 3 mm (range 2 to 4 mm). The other two patients, who received besides the transposition procedure additional surgeries of the horizontal muscles, the preoperative deviation at the distance (+ 25 and + 126 pd respectively) was reduced by 20 and 81 pd respectively. The abduction was improved by 4 and 8 mm respectively. After surgery two patients developed a vertical deviation with a maximum of 4 pd. None of the patients had complications or signs of anterior segment ischemia. The elevation and/or depression was only marginally affected. There was no diplopia in up- or downgaze. Full tendon transposition of vertical rectus muscles, augmented with lateral posterior fixation suture is

    Full Text Available A 72-year-old male patient with gall bladder perforation and small intestinal obstruction from impacted gall stone was posted for emergency laparotomy. He had congestive heart failure, severe hypertension at admission and history of multiple other coexisting diseases. On admission, he developed pulmonary oedema from systolic hypertension which was controlled by ventilatory support, nitroglycerine and furosemide. Preoperative international normalized ratio was 2.34 and left ventricular ejection fraction was only 20%. Because of risk of exaggerated fall in blood pressure during induction of anaesthesia (general or neuraxial, a transversus abdominis plane block via combined Petit triangle and subcostal technique was administered and supplemented with Propofol sedation.

    Full Text Available Campylobacter rectus is rarely associated with invasive infection. Both the isolation and the identification requirements of C. rectus are fastidious, probably contributing to an underestimation of its burden. We report the case of a 66-year-old man who developed several skull base and intracerebral abscesses after dental intervention. Campylobacter rectus was isolated from the brain biopsy. Within 45 minutes of reading the bacterial plate, the strain was accurately identified by MALDI-TOF MS. This rapid identification avoided the extra costs and delays present with 16S rRNA gene sequencing and allowed for a rapid confirmation of the adequacy of the empirical antibiotic treatment.

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

    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.

    Full Text Available Background and goal of study: After laparoscopic cholecystectomy, patients have moderate pain in the early postoperative period. Some studies shown beneficial effects of subcostal transversus abdominis plane block on reducing this pain. Our goal was to investigate influence of subcostal transversus abdominis plane block on postoperative pain scores and opioid consumption. Materials and methods: We have randomized 76 patients undergoing laparoscopic cholecystectomy to receive either subcostal transversus abdominis plane block (n = 38 or standard postoperative analgesia (n = 38. First group received bilateral ultrasound guided subcostal transversus abdominis plane block with 20 mL of 0.33% bupivacaine per side before operation and tramadol 1 mg.kg−1 IV for pain breakthrough (≥6. Second group received after operation tramadol 1 mg.kg−1/6 h as standard hospital analgesia protocol. Both groups received acetaminophen 1 g/8 h IV and metamizole 2.5 g/12 h. Pain at rest was recorded for each patient using NR scale (0–10 in period of 10 min, 30 min, 2 h, 4 h, 8 h, 12 h and 16 h after the surgery. Results and discussion: We obtained no difference between groups according age, weight, intraoperative fentanyl consumption and duration of surgery. Subcostal transversus abdominis plane block significantly reduced postoperative pain scores compared to standard analgesia in all periods after surgery. Tramadol consumption was significantly lower in the subcostal transversus abdominis plane (24.29 ± 47.54 g than in the standard analgesia group (270.2 ± 81.9 g (p = 0.000. Conclusion: Our results show that subcostal transversus abdominis plane block can provide superior postoperative analgesia and reduction in opioid requirements after laparoscopic cholecystectomy.

    The efficacy of the transversus abdominis plane (TAP) block appears to vary considerably, depending on the surgical procedure and block technique. This study aims to add to the existing literature and provide a more clear understanding of the TAP blocks role as a postoperative analgesic technique, specifically in renal allotransplant recipients. A retrospective chart review was conducted by querying the intraoperative electronic medical record system of a 1200-bed tertiary academic hospital over a 5 months period, and reviewing anesthetic techniques, as well as postoperative morphine equivalent consumption. Fifty renal allotransplant recipients were identified, 13 of whom received TAP blocks while 37 received no regional analgesic technique. All blocks were performed under ultrasound guidance, with 20 mL of 0.25% bupivacaine injected in the transversus abdominis fascial plane under direct visualization. The primary outcome was postoperative morphine equivalent consumption. Morphine consumption was compared with the two-tailed Mann-Whitney U -test. Continuous variables of patient baseline characteristics were analyzed with unpaired t -test and categorical variables with Fischer Exact Test. A P consumption was found in the group that received the TAP block at 6 h (2.46 mg vs. 7.27 mg, P = 0.0010), 12 h (3.88 mg vs. 10.20 mg, P = 0.0005), 24 h (6.96 mg vs. 14.75 mg, P = 0.0013), and 48 h (11 mg vs. 20.13 mg, P = 0.0092). The TAP block is a beneficial postoperative analgesic, opiate-sparing technique in renal allotransplant recipients.

    Transversus abdominis plane block has been recently developed as a part of multimodal post operative analgesic techniques. We compared the analgesic efficacy of this technique with local bupivacaine infiltration in patients undergoing gynaecological surgeries with pfannenstiel incision and lower midline incision under general anaesthesia. To evaluate the efficacy of ultrasound guided transversus abdominis plane block for postoperative analgesia. Patients were randomly allocated to three groups: control group (n=15), transversus abdominis plane block group (n=15), who received bilateral transversus abdominis plane blockwith 0.25% bupivacaine, and local infiltration group (n=15), who received local wound infiltration with 0.25% bupivacaine at the end of surgery. All patients received intramuscular diclofenac 12 hourly and intravenous tramadol SOS in the postoperative period. Visual analogue scores for pain were assessed at 1,2,4,8,12 and 24 hours postoperatively and these were compared between the three groups. Average tramadol consumption in 24 hours were also compared among the three groups. Data were subjected to univariate ANOVA test and chi-square test. Level of significance was set at 0.05. Visual analogue scores were significantly less in transversus abdominis plane block group and effect lasted up to 12 hours at rest postoperatively and 8 hours during cough and movement. Bilateral Transversus abdominis plane block was effective in reducing postoperative pain scores for 8 to 12 hours postoperatively. This block was also successful in reducing postoperative opioid requirement.

    Full Text Available Neste experimento, foram utilizados 6 cães, com o objetivo de avaliar a viabilidade do músculo reto do abdome pediculado para correção de defeito no diafragma. O músculo foi dissecado até próximo sua inserção e deslizado para a cavidade abdominal através de uma incisão paracostal. Após a formação de um defeito no diafragma de aproximadamente 4 x l0cm, o músculo reto do abdome foi fixado com pontos de Wolff com fio de seda 2-0. Os animais foram observados por um período de tempo determinado de 15, 30 e 60 dias, quando foram operados novamente para observação macroscópica e microscópica. Tecido conetivo e áreas de hemorragia entre o retalho e diafragma, com tecido de granulação de maturidade média, foram observados no material das biópsias aos 15 dias. Aos 30 dias, foi notado pouco tecido de granulação que, aos 60 dias, era maduro. Na região do implante, foi verificada integração tecidual entre o músculo reto do abdome e diafragma com total oclusão do defeito diafragmático, formação de tecido de granulação, onde foram observadas aderências do fígado, lobo pulmonar caudal, estômago e omento.

    Transversus abdominis plane block provides postoperative analgesia following abdominal surgery by targeting thoracolumbar nerves between the internal oblique and transversus abdominis muscles. Posterior and subcostal approaches using ultrasound guidance have been described. However there have been inconsistent results in relation to the extent of the sensory block. This observational study evaluated the distributions of sensory block following either a posterior or subcostal approach and the quality of analgesia achieved. Following ethics committee approval, 50 patients undergoing minimally invasive and major abdominal surgery were recruited. A total of 81 transversus abdominis plane blocks were performed preoperatively under real-time ultrasound guidance. Postoperatively, patients received multimodal analgesia including morphine via patient-controlled pumps. Ninety-eight percent of patients had some degree of demonstrable sensory block and the dermatomal spread differed between posterior and subcostal approaches (P interquartile range 2 to 4), the most cephalad being T10 (interquartile range T9 to T10), while the subcostal approach blocked a median of four segments (interquartile range 3 to 5), the most cephalad being T8 (interquartile range T7 to T9, P interquartile range 17 to 50 mg) at 24 hours. Median pain scores at rest and with coughing were 20 (interquartile range 10 to 35) and 50 (interquartile range 29 to 67) respectively at 24 hours. The posterior approach appears to be more appropriate for lower abdominal surgery and the subcostal approach better suited to upper abdominal surgery. Whichever approach is used, transversus abdominis plane block is only one component of a multimodal analgesic technique.

    2002-11-01

    To present an avulsion injury of the rectus muscle after orbital trauma, usually the inferior rectus, and detail its diagnosis and operative repair. Forty-three patients underwent repair of flap tears of 62 rectus muscles. During surgery, we found the muscle abnormality was often subtle, with narrowing or thinning of the remaining attached global layer of muscle. The detached flap of external (orbital) muscle was found embedded in surrounding orbital fat and connective tissue. Retrieval and repair were performed in each case. The causes of orbital trauma were as follows: orbital fractures (15 patients), blunt trauma with no fracture (11 patients), suspected trauma but did not undergo computerized tomographic scan (12 patients), and status after retinal detachment repair (5 patients). Of note, 15 of the 43 patients (35%) underwent repair of the flap tear alone, without any additional orbital or strabismus surgery. Diagnostically, the predominant motility defect in 45 muscles was limitation toward the field of action of the muscle, presumably as a result of a tether created by the torn flap; these tethers simulated muscle palsy. Seventeen muscles were restricted away from their field of action, simulating entrapment. The direction taken by the flap during healing determined the resultant strabismus pattern. All patients with gaze limitation toward an orbital fracture had flap tears. The worst results after flap tear repair were seen in patients (1) who had undergone orbital fracture repair before presentation, (2) who had undergone previous attempts at strabismus repair, and (3) who had the longest intervals between the precipitating event and the repair. The best results were obtained in patients who underwent simultaneous fracture and strabismus repair or early strabismus repair alone. Avulsion-type flap tears of the extraocular muscles are a common cause of posttraumatic strabismus. Early repair produces the best results, but improvement is possible despite long

    Enhanced recovery protocols frequently use multimodal postoperative analgesia to improve postoperative outcomes in patients undergoing colorectal surgery. The purpose of this study was to evaluate liposomal bupivacaine use in transversus abdominis plane blocks on postoperative pain scores and opioid use after colorectal surgery. This was a retrospective cohort study comparing outcomes between patients receiving nonliposomal anesthetic (n = 104) and liposomal bupivacaine (n = 303) blocks. The study was conducted at a single tertiary care center. Patients included those identified within an institutional database as inpatients undergoing colorectal procedures between 2013 and 2015 who underwent transversus abdominis plane block for perioperative analgesia. The study measured postoperative pain scores and opioid requirements. Patients receiving liposomal bupivacaine had significantly lower pain scores for the first 24 to 36 postoperative hours. Pain scores were similar after 36 hours. The use of intravenous opioids among the liposomal bupivacaine group decreased by more than one third during the hospitalization (99.1 vs 64.5 mg; p = 0.040). The use of ketorolac was also decreased (49.0 vs 18.3 mg; p bupivacaine group but did not achieve statistical significance. The study was limited by its retrospective, single-center design and heterogeneity of block administration. Attenuated pain scores observed with liposomal bupivacaine use were associated with significantly lower intravenous opioid and ketorolac use, suggesting that liposomal bupivacaine-containing transversus abdominis plane blocks are well aligned with the opioid-reducing goals of many enhanced recovery protocols.

    To demonstrate three reconstructive advantages of the perforator based rectus free tissue transfer: long pedicle, customizable adipose tissue, and volume reconstruction without muscle atrophy within a contained space. Thirty patients with defects of the head and neck were reconstructed with the perforator based rectus free tissue transfer. Transplant success was 93%. Mean pedicle length was 13.4cm. Eleven patients (37%) had vessel-poor necks and the long pedicle provided by this transplant avoided the need for vein grafts in these patients. Adipose tissue was molded in 17 patients (57%). Twenty-five patients (83%) had defects within a contained space, such as the orbit, where it was critical to have a transplant that avoided muscle atrophy. The perforator based rectus free tissue transfer provides a long pedicle, moldable fat for flap customization, and is useful in reconstruction of defects within a contained space where volume loss due to muscle atrophy is prevented.

    2012-06-01

    In unilateral congenital superior oblique palsy, a large hypertropia is sometimes associated with ipsilateral contracture of the superior rectus muscle and apparent overaction of the contralateral superior oblique. Ipsilateral double elevator weakening is one surgical approach; however, this procedure could compromise supraduction. We report a series of three consecutive patients who underwent ipsilateral superior rectus and inferior oblique recessions for unilateral superior oblique palsy. Intraoperatively, all three patients were found to have a lax ipsilateral superior oblique tendon. Postoperatively, all three patients had satisfactory correction of the hypertropia and abnormal head position with minimal supraduction defect. This procedure seems to be an acceptable initial surgical option for treating congenital superior oblique muscle palsy with ipsilateral contracture of the superior rectus muscle, even when the ipsilateral superior oblique tendon is lax.

Bilateral ultrasound-guided TAP blocks were performed with an initial bolus of 0.5% ropivacaine 20 mL per side, followed by catheter insertion. After surgery, the continuous infusion group received 0.2% ropivacaine 8 mL/hour on each side and the intermittent bolus group received doses of 0.2% ropivacaine 20 mL per side every 8 hours for 48 hours. Both groups received intravenous fentanyl patient-controlled analgesia and regular oral paracetamol. Parameters recorded included numerical rating scores for pain and post-operative analgesic consumption at baseline (time 0 and at 1 hour, 1 day and 2 days post-operatively. The duration of catheter insertion, complications, patient satisfaction and information regarding costs were also recorded. Patient satisfaction was assessed utilizing a 4-point

    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.

    To study the different ways of expressing the force-elongation relationship in medial rectus muscles in esotropia with and without muscular restriction. Twenty-nine passive force-elongation curves were obtained without restriction (group I, n = 13) and with restriction (group II, n = 10) by means of a manual pachymeter and a digital dynamometer. In group I, the mean age was 14 years and 7 days and the mean esotropia was 53.88(Delta) while in group II the mean age was 35 years and 5 days and the mean esotropia was 60.5(Delta). Comparisons of structural muscular parameters between groups I and II were made for length (38.69 +/- 0.75 vs. 32.48 +/- 1.84 mm, p elongation relationship, whether normalized or not, followed an exponential curve. The constant c, which represents force when the elongation is zero, remained the same in all curves. In contrast, the constant b, which represents the slope of the curve, showed a significant difference between the two groups only for the curves of force-absolute elongation and tension-absolute elongation. The results imply that the constant b is better for characterizing the difference between the behavior of the medial rectus in esotropia with and without restriction. In addition, the elongation normalization showed that the contractile component is similar between the two groups and, therefore, the classical way of analysis, which does not employ normalization, is appropriate to correlate muscle properties with clinical findings.

    Diplopia is a common subjective complaint that can be the first manifestation of a serious pathology. Here, we report a rare case of midbrain infarction involving the lateral subnucleus of the oculomotor nuclear complex presenting as diplopia, with no other stroke manifestations. An 83-year-old right-handed white man with past medical history of diabetes mellitus, hypertension, dyslipidemia, and coronary artery disease presented to the emergency department (ED) with diplopia and unsteadiness. Two days prior to admission, the patient woke up with constant horizontal diplopia and unsteadiness, which limited his daily activities and led to a fall at home. He denied any weakness, clumsiness, nausea, vomiting, photophobia, fever, or chills. Ocular exam showed a disconjugate gaze at rest, weakness of the left medial rectus muscle, impaired convergence test, and bilateral 3-mm reactive pupils. The diplopia resolved by closing either eye. The remaining extraocular muscles and other cranial nerves were normal. There was no nystagmus, ptosis, or visual field deficit. Sensation, muscle tone, and strength were normal in all extremities. Magnetic resonance imaging (MRI) of the brain revealed a tiny focus of restricted diffusion in the left posterior lateral midbrain. A thorough history and physical examination is essential to diagnose and manage diplopia. Isolated extraocular palsy is usually thought to be caused by orbital lesions or muscular diseases. Here, we report a case of midbrain infarction manifested as isolated medial rectus palsy.

  10. Validating the Use of Rectus Muscle Fragment Welding to Control Presacral Bleeding During Rectal Mobilization

    2004-01-01

    Full Text Available The incidence of presacral bleeding during rectal mobilization is low, but such bleeding may be massive and even fatal. Haemostasis can be difficult to achieve using conventional methods because of the complex interlacing of the venous network at the sacral periosteum. Historically, pelvic packing and metallic thumbtacks have been the more commonly used methods in our institution. However, the need for repeat surgery to remove the packs and the difficulties encountered in tack application have forced us to explore other methods. In 1994, the procedure termed muscle fragment welding, which uses electrocautery through a rectus muscle fragment, was introduced to control presacral bleeding. From January 1999 to February 2002, six of 416 patients undergoing pelvic surgery in our institution developed massive presacral haemorrhage and, therefore, this technique was used. Haemostasis was immediate and permanent. No major untoward postoperative events such as re-bleeding or infection were noted. One case developed a second-degree burn in the right elbow due to a misplaced ground conduction plate. Rectus muscle fragment welding is, in our experience, an effective and practical method of controlling presacral haemorrhage.

    Previous studies examining the efficacy of transversus abdominis plane block after caesarean section have mostly been in parturients under spinal anaesthesia. We postulated that the advantage of performing transversus abdominis plane block after caesarean section might be even more obvious after general anaesthesia, resulting in reduced 24-h consumption of morphine. DESIGN, SETTING, PATIENTS AND INTERVENTIONS: In this single centre, randomised double-blind controlled trial, 40 women who underwent caesarean delivery under general anaesthesia were allocated randomly to receive a transversus abdominis plane block or no block. In those who received the block, 20 ml of levobupivacaine 2.5 mg ml was deposited bilaterally into the transversus abdominis plane under ultrasound guidance using a Sonosite Titan (SonoSite, Bothell, Washington, USA) 7-13 MHz linear transducer at the end of surgery when the patient was still anaesthetised. We recorded patient-controlled intravenous morphine use for 24 h, pain scores at rest and activity, sedation, nausea and vomiting, use of antiemetic medication and overall maternal satisfaction. The primary outcome was 24-h morphine consumption. Patients who received the transversus abdominis plane block used significantly less morphine in 24 h than those in the control group [12.3 (2.6) vs. 31.4 mg (3.1), Pplane block reduced morphine consumption following caesarean section under general anaesthesia, with increased maternal satisfaction.

  12. Transversus abdominis is part of a global not local muscle synergy during arm movement.

    Morris, S L; Lay, B; Allison, G T

    2013-10-01

    The trunk muscle transversus abdominis (TrA) is thought to be controlled independently of the global trunk muscles. Methodological issues in the 1990s research such as unilateral electromyography and a limited range of arm movements justify a re-examination of this theory. The hypothesis tested is that TrA bilateral co-contraction is a typical muscle synergy during arm movement. The activity of 6 pairs of trunk and lower limb muscles was recorded using bilateral electromyography during anticipatory postural adjustments (APAs) associated with the arm movements. The integrated APA electromyographical signals were analyzed for muscle synergy using Principle Component Analysis. TrA does not typically bilaterally co-contract during arm movements (1 out of 6 participants did). APA muscle activity of all muscles during asymmetrical arm movements typically reflected a direction specific diagonal pattern incorporating a twisting motion to transfer energy from the ground up. This finding is not consistent with the hypothesis that TrA plays a unique role providing bilateral, feedforward, multidirectional stiffening of the spine. This has significant implications to the theories underlying the role of TrA in back pain and in the training of isolated bilateral co-contraction of TrA in the prophylaxis of back pain.

    Transversus abdominis plane block (TAPb) is an analgesic adjunct used for abdominal surgical procedures. Liposomal bupivacaine (LB) demonstrates prolonged analgesic effects, up to 72 hours. We evaluated the analgesic efficacy of TAPb using LB for patients undergoing open abdominal wall reconstruction (AWR). Fifty patients undergoing AWR with TAPb using LB (TAP-group) were compared with a matched historical cohort undergoing AWR without TAPb (control group). Outcome measures included postoperative utilization of morphine equivalents, numerical rating scale pain scores, time to oral narcotics, and length of stay (LOS). Cohorts were matched demographically. No complications were associated with TAPb or LB. TAP-group evidenced significantly reduced narcotic requirements on operative day (9.5 mg vs 16.5 mg, P = .004), postoperative day (POD) 1 (26.7 mg vs 39.5 mg, P = .01) and POD2 (29.6 mg vs 40.7 mg, P = .047) and pain scores on operative day (5.1 vs 7.0, P consumption and improved pain control. TAPb allowed for earlier discontinuation of intravenous narcotics and shorter LOS. Intraoperative TAPb with LB appears to be an effective adjunct for perioperative analgesia in patients undergoing open AWR. Copyright © 2016 Elsevier Inc. All rights reserved.

    To determine if transversus abdominis plane anesthetic blockage (TAP block) diminishes early postoperative pain scores and facilitates ambulatory management following total laparoscopic hysterectomy. Randomized triple blind trial. Gynecological endoscopy unit at a referral center for laparoscopic surgery. A total of 197 patients. Comparison of a treatment group receiving TAP block with bupivacaine 0.25% and placebo group with comparably placed bilateral injection of sterile saline solution. Pain scores at discharge 24, 48 and 72 h after surgery, opioid requirement after procedure. Patients who had TAP block had a significant reduction in their pain score at discharge compared with the placebo group (p = 0.017). There were no significant differences in the pain scores between groups at 24 h (95% CI 1.36-0.133, p = 0.237), 48 h (95% CI 0.689-0.465, p = 0.702) and 72 h (95% CI -0.631 to 0.223, p = 0.347). No differences were found between the groups regarding opioid requirements following the procedure (χ(2)  = 3.62, p = 0.46). Although TAP block after a total laparoscopic hysterectomy reduced the pain score at discharge compared with placebo, its role in this setting is debatable due to the possible lack of clinical significance of the small difference found. © 2014 Nordic Federation of Societies of Obstetrics and Gynecology.

    Full Text Available Background and objectives: A transversus abdominis plane block is a peripheral block method that has been used successfully for pain relief after total abdominal hysterectomy. However, the effects of the combination of the transversus abdominis plane block and general anesthesia on analgesic and anesthetic requirements remain unclear. This randomized placebo-controlled study is aimed to evaluate the effects of transversus abdominis plane block on analgesic and anesthetic consumption during total abdominal hysterectomy under general anesthesia. Methods: Sixty-six women undergoing total abdominal hysterectomy were randomized into two groups to receive general anesthesia alone (control group or with transversus abdominis plane block using 20 mL of 0.25% bupivacaine (transversus abdominis plane group. Intraoperative remifentanil and sevoflurane consumption were recorded. We also evaluated the postoperative pain, nausea, quality of recovery scores and rescue analgesic requirement during postoperative 24 hours. Results: The total remifentanil and sevoflurane consumption is significantly lower in transversus abdominis plane group; respectively mean (SD 0.130 (0.25 vs. 0.094 (0.02 mcg.kg−1.min−1; p < 0.01 and 0.295 (0.05 vs. 0.243 (0.06 mL.min−1; p < 0.01.

    Analgesic efficacy of ultrasound-guided transverse abdominis plane block, administered a little more medially, just close to the origin of the transverse abdominis muscle has not yet been investigated in patients undergoing unilateral inguinal hernia repair. We hypothesised that medial transverse abdominis plane block would provide comparable postoperative analgesia to ilioinguinal-iliohypogastric nerve block in inguinal hernia repair patients. This prospective, randomised trial was conducted in 50 ASA I and II male patients≥18 years of age. Patients were randomised into two groups to receive either pre-incisional ipsilateral ultrasound-guided ilioinguinal-iliohypogastric nerve block or medial transverse abdominis plane block, with 0.3ml/kg of 0.25% bupivacaine. Our primary objective was postoperative 24-hour analgesic consumption and secondary outcomes included pain scores, time to first request for rescue analgesic and side effects, if any, in the postoperative period. There was no significant difference in the total postoperative analgesic consumption [group I: 66.04mg; group II: 68.33mg (P value 0.908)]. Time to first request for rescue analgesic was delayed, though statistically non-significant (P value 0.326), following medial transverse abdominis plane block, with excellent pain relief seen in 58.3% patients as opposed to 45.8% patients in ilioinguinal-iliohypogastric nerve block group. Medial transverse abdominis plane block being a novel, simple and easily performed procedure can serve as an useful alternative to ilioinguinal-iliohypogastric nerve block for providing postoperative pain relief in inguinal hernia repair patients.

  17. Reconstruction of the radiation-damaged chest wall

    In the patient with a radiation ulcer of the chest wall, the first question is whether the lesion contains persistent or recurrent cancer. It is also important to determine whether any other local problems such as mediastinal abscess may interfere with the reconstruction. Whether or not cancer is present, all nonviable tissue must be removed. If cancer is not present, and a partial thickness of the chest remains, the authors prefer transposition of the greater omentum for repair. If cancer is present, the physiologic defect resulting from cancer resection and wound debridement is far more severe, and a muscle or musculocutaneous flap usually is appropriate. The pectoralis major, latissimus dorsi, external oblique, rectus abdominis, and trapezius muscles have been utilized; the authors most often use the pectoralis or latissimus muscles. 27 references

  18. Combined Gluteus and Pudendal Thigh Flap Reconstruction of Vaginal Defects following Robotic Abdominoperineal Resection

    Directory of Open Access Journals (Sweden)

    Kasandra R. Dassoulas, MD

    2017-09-01

    Full Text Available Summary:. Low-lying rectal cancers are being treated more frequently with robotic-assisted abdominoperineal resection, obviating the need for laparotomy and the ability to raise vertical rectus abdominis musculocutaneous flaps. For female patients, posterior vaginectomy often accompanies the resection. Combined pudendal thigh flaps as an extension of bilateral gluteus advancement flaps allow for posterior vaginal resurfacing with thin pliable fasciocutaneous flaps, which rest on the gluteal flap soft-tissue bulk that obliterates the pelvic dead space. For patients with advanced cancers who have had neoadjuvant chemoradiation, the pudendal skin paddle can be planned more laterally to bring in healthier medial thigh skin. The donor incisions lie within the gluteal cleft and crease and groin creases recapitulating normal perineal anatomy and aesthetics.

    A 54-year-old man underwent left upper lobectomy with c-stage IIIA lung squamous cell carcinoma after concurrent chemo-radiotherapy. Radiation pneumonitis focusing on the residual left S 6 appeared after operation. Following steroid pulse treatment, the pneumonitic focus was cavitated and proceeded to pulmonary abscess. Although chest drainage was performed, control of the pulmonary fistula was poor, so an operation was performed. Pulmonary decortication and pleurodesis were performed, but failed to control the fistula and infection. Finally, thoracoplasty, omentoplasty and free rectus abdominis musculocutaneous flap were filled in intrathorasic to manage the fistula. In this case of operation following concurrent chemo-radiotherapy, the original recovery power declined. We therefore conclude this was an intractable case of empyema. (author)

    The rectus femoris (RF) muscle flap, which is widely used to cover groin infected vascular grafts, is usually harvested through distal tendon division and an extensive muscle elevation and transposition into the groin wound defect. A case of a vascular prosthetic graft infection in the groin was successfully controlled after coverage with an RF flap that was harvested based on proximal portion mobilization instead of the conventional distal one. This case suggests that the RF muscle flap based on proximal insertion mobilization is a feasible, effective, technically simpler, and less invasive alternative to cover infected vascular grafts in the groin.

    We present the case of a 54 year-old man presenting with a right Brown-Séquard plus syndrome (BSPS) after a traumatic cervical spinal cord injury. After being operated on with selective tibial neurotomy and triceps surae lengthening because of a right spastic equinus foot, he developed a gait disorder at high speed. The patient complained about an instability of the right knee. Observational gait analysis exhibited an oscillating, flexion/extension motion of the right knee during stance, which was confirmed by gait analysis. Dynamic electromyographic recordings exhibited a clonus of the right rectus femoris (RF) during stance. The spastic activity of the RF and the abnormal knee motion totally reversed after a motor nerve block of the RF, as well as after botulinum toxin type A injection into the RF. We emphasize that complex, spastic gait disorders can benefit from a comprehensive assessment including gait analysis and nerve blocks. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

    Purpose To further chemically characterize palisade endings in extraocular muscles in rhesus monkeys. Methods Extraocular muscles of three rhesus monkeys were studied for expression of the calcium-binding protein calretinin (CR) in palisade endings and multiple endings. The complete innervation was visualized with antibodies against the synaptosomal-associated protein of 25 kDa and combined with immunofluorescence for CR. Six rhesus monkeys received tracer injections of choleratoxin subunit B or wheat germ agglutinin into either the belly or distal myotendinous junction of the medial or inferior rectus muscle to allow retrograde tracing in the C-group of the oculomotor nucleus. Double-immunofluorescence methods were used to study the CR content in retrogradely labeled neurons in the C-group. Results A subgroup of palisade and multiple endings was found to express CR, only in the medial and inferior rectus muscle. In contrast, the en plaque endings lacked CR. Accordingly, within the tracer-labeled neurons of the C-group, a subgroup expressed CR. Conclusions The study indicates that two different neuron populations targeting nontwitch muscle fibers are present within the C-group for inferior rectus and medial rectus, respectively, one expressing CR, one lacking CR. It is possible that the CR-negative neurons represent the basic population for all extraocular muscles, whereas the CR-positive neurons giving rise to CR-positive palisade endings represent a specialized, perhaps more excitable type of nerve ending in the medial and inferior rectus muscles, being more active in vergence. The malfunction of this CR-positive population of neurons that target nontwitch muscle fibers could play a significant role in strabismus.

    Anomalies of the brachial plexus and its terminal branches are not uncommon. Variations in the course and branches of the musculocutaneous nerve have been noted (Clemente, 1985; Bergman et al. 1988) and its absence was reported by Le Minor (1990). Several anomalies were present in the left plexus of a 59-y-old Japanese man (Fig.). There were no anterior and posterior divisions of the middle trunk, although there were communications between the posterior, medial and lateral cords. The musculocutaneous nerve was absent (Le Minor, 1990) and the medial and lateral roots of the median nerve did not unite in the axillary fossa but in the upper arm about 5 cm distal to the lower border of latissimus dorsi (Adachi, 1928; Buch-Hansen, 1955). The hitherto unreported findings were branches arising directly from the lateral cord to supply coracobrachialis, both heads of biceps brachii and brachialis. The lateral cutaneous nerve of the forearm was derived from the lateral cord with a small contribution from the medial root of the median nerve. Since there were communications between the posterior cord (a continuation of the middle trunk) and the medial and lateral cords, it is theoretically possibly, but not proven, that the root values of branches innervating the flexor muscles of the arm and forearm and the skin of lateral border of the forearm were normal.

    The ultrasound-guided transversus abdominis plane (TAP) block is a useful tool in controlling postoperative pain following abdominal surgery. The bilateral ultrasound-guided TAP blocks successfully managed the pain of a patient presenting with hypoxemia and respiratory failure in the Post-anesthesia Care Unit, following a laparotomy for small bowel obstruction during general anesthesia. The TAP block reduced systemic opioid requirements and opioid-induced sedation and respiratory depression, improved patient compliance with non-invasive positive pressure ventilation, and prevented the need for intubation and ventilation in the intensive care unit.

    To evaluate the effectiveness of a proposed new protocol for the primary treatment for very large angle esotropia: two muscle horizontal rectus muscle surgery with simultaneous botulinum toxin A injection in a small pilot study. Eight patients who had esotropia at near (ET') greater than 60 prism diopters (in actuality 70 to 100 prism diopters ET') underwent 2 muscle horizontal rectus surgery with simultaneous botulinum toxin A injection of the medial rectus intraoperatively. This was the only surgical procedure for all patients included in this report. Seven patients underwent bilateral medial rectus recession and bilateral injection, and one patient underwent a unilateral medial rectus recession / lateral rectus resection procedure with unilateral medial rectus injection. Postoperatively, 6 of the 8 patients demonstrated residual esotropia at near of less than 10 prism diopters and were considered "successful" by the conventional criteria of binocular alignment within 8 prism diopters of orthotropia. Two undercorrections occurred in patients with 100 and 85 prism diopters of preop ET' respectively. But 3 other patients with such large deviations had satisfactory results. All patients and families were satisfied with postoperative binocular alignment, so no further surgery was undertaken. The patient who underwent unilateral surgery had the least surgical effect and was the largest undercorrection, probably because only one medial rectus received a Botox injection. Considering only the bilateral cases, results were "successful" in 6 of 7 cases. Most patients suffered an extended period of Botox induced exotropia in the postop' period before recovery from the paresis. One patient had a transient, successfully treated, postoperative strabismic amblyopia while exotropic. Bilateral medial rectus recession with simultaneous botulinum injection is a safe and effective primary surgical procedure for very large angle esotropia. A more extensive study is indicated to

    Transversus abdominis release (TAR) is a safe, effective strategy to repair complex ventral incisional hernia (VIH); however, open TAR (o-TAR) often necessitates prolonged hospitalization. Robot-assisted TAR (r-TAR) may benefit short-term outcomes and shorten convalescence. This study compares 90-day outcomes of o-TAR and r-TAR for VIH repair. A single-center, retrospective review of patients who underwent o-TAR or r-TAR for VIH from 2015 to 2016 was conducted. Patient and hernia characteristics, operative data, and 90-day outcomes were compared. The primary outcome was hospital length of stay, and secondary metrics were morbidity, surgical site events, and readmission. Overall, 102 patients were identified (76 o-TAR and 26 r-TAR). Patients were comparable regarding age, gender, body mass index, and the presence of co-morbidities. Diabetes was more common in the open group (22.3 vs. 0%, P = 0.01). Most VIH defects were midline (89.5 vs. 83%, P = 0.47) and recurrent (52.6 vs. 58.3%, P = 0.65). Hernia characteristics were similar regarding mean defect size (260 ± 209 vs. 235 ± 107 cm 2 , P = 0.55), mesh removal, and type/size mesh implanted. Average operative time was longer in the r-TAR cohort (287 ± 121 vs. 365 ± 78 min, P VIH offers the short-term benefits of low morbidity and decreased hospital length of stay compared to open TAR.

    Laparoscopic surgery reduces pain after donor nephrectomy; however, most patients still require a significant amount of postoperative parenteral opiate analgesia. Therefore, there is a need to investigate techniques that might further reduce postoperative pain. This study assessed the safety and efficacy of using a transversus abdominis plane (TAP) block in a randomized, double-blind, placebo-controlled trial. Forty-six patients were analyzed in the trial and were randomized to undergo the TAP block procedure with either bupivacaine (n=24) or saline placebo (Control n=22) injected into the muscle plane. Prefilled syringes were dispensed with the group allocation concealed to maintain blinding. After surgery, the amount of morphine, level of pain, and measures of recovery were recorded. The amount of morphine used 6 hr after surgery was significantly lower in patients receiving TAP block with bupivacaine compared with the control (presented as mean [SD], 12.4 [8.4] vs. 21.2 [14.0] mg; P=0.015). However, the total amount of morphine used was similar in both groups 45.6 [31.4] vs. 52.7 [28.8] mg; P=0.771. Patients in the bupivacaine group experienced significantly less pain on postoperative days 1 (score, 19 [15] vs. 37 [20]; P=0.003) and 2 (score, 11 [10] vs. 19 [13]; P=0.031). Recovery and postoperative hospital stay were similar in both groups. There were no complications associated with the procedure. The TAP block procedure is beneficial in reducing postoperative pain and early morphine requirements in laparoscopic live-donor nephrectomy.

    Multiple studies suggest that transversus abdominis plane (TAP) block (without intrathecal morphine) after Caesarean section (CS) reduces post-operative morphine consumption. In our study, we wanted to compare the analgesic effect of TAP block with infiltration of the wound after CS. We included 60 pregnant women scheduled for elective CS under spinal anaesthesia in a randomised, single-centre, double-blind study. Thirty patients received ultrasound-guided TAP block using 20 ml bupivacaine 0.25% with adrenaline 5 μg/ml bilaterally and 20 ml normal saline as wound infiltration (TAP group). The other 30 patients (the control group) received normal saline 20 ml bilaterally in the TAP, and 20 ml bupivacaine 0.25% with adrenaline 5 μg/ml as wound infiltration. The main outcome was cumulative morphine consumption at 48 h after surgery. In addition, continuous morphine consumption, pain scores and side effects were registered. Fifty-seven patients completed the study. Cumulative morphine consumption at 48 h (mean±standard deviation) was 41±34 mg in the TAP group and 38±27 mg in the control group (P=0.7); a difference of 3 mg (95% confidence interval -13 to 19 mg). Morphine consumption at any time up to 48 h was virtually identical in both groups. Side effects were similar, except for a higher degree of sedation in the TAP group (P=0.04). Compared with wound infiltration with local anaesthetics, TAP block did not reduce cumulative morphine consumption following CS. The TAP block was associated with more pronounced sedation. © 2015 The Acta Anaesthesiologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

    Transversus abdominis plane (TAP) block is a recently introduced regional anesthesia technique that is used for postoperative pain reduction in some abdominal surgeries. The present study evaluated the efficacy of the TAP block on the post laparoscopic cholecystectomy pain intensity and analgesic consumption. Fifty-four patients were enrolled in three groups: TAP block with normal saline (Group 1, n = 18); TAP block with bupivacaine (Group 2, n = 18); and TAP block with bupivacaine plus sufentanil (Group 3, n = 18). The time to the first fentanyl request, fentanyl consumption in the 24 hours following surgery, and postoperative pain intensity at 30 minutes, 1 hour, 6 hours, 12 hours, and 24 hours following discharge for recovery were measured and recorded. The total amount of 24-hour fentanyl consumption was higher in Group 1 (877.8 ± 338.8 μg) than either Group 2 (566.7 ± 367.8 μg) or Group 3 (555.5 ± 356.8 μg; p = 0.03). Postoperative pain score was higher in Group 1 than intervention groups (p = 0.006); however, there was no significant difference in intervention groups. The time to the first fentanyl request in Group 1 (79.44 ± 42.2) was significantly lower than Group 3 (206.38 ± 112.7; p = 0.001). The present study demonstrated that bilateral TAP block with 0.5% bupivacaine reduces post laparoscopic cholecystectomy pain intensity and fentanyl request and prolongs time to the first analgesic request. Adding sufentanil to the block solution reduced neither pain intensity nor fentanyl further consumption. Copyright © 2015. Published by Elsevier B.V.

    Full Text Available Background and Aims: Transversus abdominis plane (TAP block is suitable for operations where parietal pain is a major cause of pain. Renal transplant recipients are ideally suited to gain maximum benefit from TAP block as the incision classically involves the lower abdomen. This study was conducted to evaluate the analgesic efficacy of continuous TAP block in transplant recipients. Material and Methods: In a prospective double-blind study, 40 chronic renal failure patients undergoing open renal transplant were randomly divided into two groups. At the end of surgery during closure, a multiorifice epidural catheter was placed in TAP plane. Study group (Group S received Inj bupivacaine bolus 1 mg/kg (0.25% followed by infusion 0.25 mg/kg (0.125% through the catheter, whereas control group (Group C received normal saline through the catheter. Inj pentazocine (0.3 mg/kg was given as rescue analgesic at visual analogue score (VAS > 3 in any group at rest or on movement. The analgesic efficacy was judged by VAS, time of first rescue analgesic, and total analgesic consumption in 24 h. Results: Patients in Group S had significant lower VAS scores, longer time to first rescue analgesic (270 ± 347.96 vs. 42.85 ± 32.27 min and lower pentazocine consumption (9.75 ± 13.95 vs. 56.42 ± 12.46 mg in 24 h. There was significant sedation in Group C. Conclusion: The TAP catheter technique for postoperative pain control after renal transplant has proved to be effective in relieving the postoperative pain after renal transplant with less pentazocine requirement and less sedation.

    To evaluate and compare intercostal-iliac transversus abdominis plane (TAP) and oblique subcostal TAP (OSTAP) blocks for multimodal analgesia in patients receiving laparoscopic cholecystectomy. A prospective, randomized, double-blinded clinical study. Operating room, postoperative recovery area, and ward. In total, 60 laparoscopic cholecystectomy patients (43 women, 17 men, American Society of Anesthesiologists grades I-II) were enrolled from the general surgery department of our tertiary care center. The patients were assigned to 1 of the 3 groups. Group 1 received TAP blocks (n=20), group 2 received OSTAP blocks (n=20), and group 3 patients were used as controls and received patient-controlled analgesia (PCA) only (n=20). After the induction of anesthesia, blocks were performed bilaterally in study groups 1 and 2, using 20mL of lidocaine (5mg/mL). PCA with intravenous tramadol was routinely provided for all patients during the first 24hours. The intraoperative use of remifentanil, postoperative visual analog scale (VAS) scores, demand for PCA, and total analgesic consumption were recorded. The patients in the control group had greater analgesic demands and analgesic consumption than did those in groups 1 and 2. However, patients in the OSTAP group had lower VAS scores than did those in groups 1 and 3. The demand for analgesia was greater in the control group than in groups 1 and 2. Moreover, lower VAS scores were recorded in the OSTAP group than in groups 1 and 3 and were positively correlated with total PCA consumption among all patients. However, postoperative VAS scores were negatively correlated with the total intraoperative consumption of remifentanil at 24hours. TAP and OSTAP blocks improved postoperative analgesia in patients receiving laparoscopic cholecystectomy, which resulted in lower VAS scores and reduction in total analgesic consumption.

    Full Text Available Objectives We hypothesized that preoperative (pre-op ultrasound (US-guided posterior transversus abdominis plane block (TAP and US-guided ilioinguinal and iliohypogastric nerve block (ILI+IHG will produce a comparable analgesia after Lichtenstein patch tension-free method of open inguinal hernia repair in adult men. The genital branch of the genitofemoral nerve will be blocked separately. Methods This is a prospective, randomized, controlled, and observer-blinded clinical study. A total of 166 adult men were randomly assigned to one of three groups: a pre-op TAP group, a pre-op ILI+IHG group, and a control group. An intraoperative block of the genital branch of the genitofemoral nerve was performed in all patients in all three groups, followed by postoperative patient-controlled intravenous analgesia with morphine. The pain intensity and morphine consumption immediately after surgery and during the 24 hours after surgery were compared between the groups. Results A total of 149 patients completed the study protocol. The intensity of pain immediately after surgery and morphine consumption were similar in the two “block” groups; however, they were significantly decreased compared with the control group. During the 24 hours after surgery, morphine consumption in the ILI+IHG group decreased compared with the TAP group, as well as in each “block” group versus the control group. Twenty-four hours after surgery, all evaluated parameters were similar. Conclusion Ultrasound-guided ILI+IHG provided better pain control than US-guided posterior TAP following the Lichtenstein patch tension-free method of open inguinal hernia repair in men during 24 hours after surgery.

    Transversus abdominis plane (TAP) block and local anesthetic wound infiltration provide analgesia after cesarean delivery. Studies comparing the 2 techniques are scarce, with conflicting results. This double-blind, randomized controlled trial aimed to compare bilateral ultrasound-guided TAP block with single-shot local anesthetic wound infiltration for analgesia after cesarean delivery performed under spinal anesthesia. We hypothesized that the TAP block would decrease postoperative cumulative fentanyl consumption at 24 hours. Eligible subjects were American Society of Anesthesiologists physical status II parturients with full-term singleton pregnancies undergoing elective cesarean delivery under spinal anesthesia. Exclusion criteria were: 40 years of age; height consumption at 24 hours. Secondary outcomes were the time to the first postoperative fentanyl dose, cumulative fentanyl consumption at 2, 4, 6, and 12 hours, pain scores at rest and on movement at 2, 4, 6, 12, and 24 hours, the deepest level of sedation, the incidence of side effects (nausea and vomiting and pruritis), and patient satisfaction. Data from 78 patients (39 patients in each group) were analyzed. The mean ± SD of cumulative fentanyl consumption at 24 hours was 157.4 ± 63.4 μg in the infiltration group and 153.3 ± 68.3 μg in the TAP group (difference in means [95% confidence interval] is 4.1 [-25.6 to 33.8] μg; P = .8). There were no significant differences between the 2 groups in the time to the first postoperative fentanyl dose, cumulative fentanyl consumption at 2, 4, 6, and 12 hours, pain scores at rest and on movement at 2, 4, 6, 12, and 24 hours, the deepest level of sedation, and patient satisfaction. The incidence of side effects (nausea and vomiting and pruritis) was low in the 2 groups. TAP block and wound infiltration did not significantly differ regarding postoperative fentanyl consumption, pain scores, and patient satisfaction in parturients undergoing cesarean delivery under

    The objective of this study was to address the efficacy of transversus abdominis plane (TAP) blocks in pain management among women who undergo elective hysterectomy for benign pathology in both open and minimally invasive surgeries. We performed a systematic review by searching for bibliographic citations from Medline, Embase and Cochrane Library. MeSH headings for TAP blocks and hysterectomy were combined and restricted to the English language. We included RCTs comparing TAP blocks to placebo or no block in patients who underwent elective hysterectomy. Pain was measured using a visual analog score (VAS) on a scale of 0-100. We calculated pooled mean differences in VAS and total morphine consumption at 2 and 24 hours by performing a random effects meta-analysis. Fourteen studies met the inclusion criteria, comprising 855 participants. At 2 hours, mean VAS scores for patients who underwent TAP blocks were significantly lower after both total abdominal hysterectomy (TAH) (mean difference -14.97 [CI: -20.35- -9.59]) and total laparoscopic hysterectomy (TLH) (-18.16 [CI: -34.78- -1.53]) compared to placebo or no block. Pain scores at 24 hours for patients who underwent TAPB were significantly lower after both TAH (-10.09 [CI: -17.35- -2.83]) and TLH (-9.12 [CI: -18.12- -0.13]) compared to placebo or no block. Mean difference in morphine consumption was -9.53 mg (CI -15.43- -3.63) for TAH and -3.15 mg (CI: -8.41- 2.12) for TLH. In conclusion, TAP blocks provide significant postoperative early and delayed pain control compared to placebo or no block among women who undergo hysterectomy. There was reduced morphine consumption among patients who underwent TAH, but not after TLH. Copyright © 2018. Published by Elsevier Inc.

    Use of transversus abdominis plane (TAP) block for postoperative analgesia is continuously increasing. However, few studies have investigated intraoperative effects of TAP block. We aimed to study the effects of TAP block in terms of cost-effectiveness and consumption of inhalation agents. Forty patients undergoing laparoscopic cholecystectomy were enrolled in this study. Patients were randomly divided into 2 groups: Group 1 (n=20) patients received TAP block and Group 2 (n=20) patients did not receive TAP block. Standard anesthesia induction was used in all patients. For the maintenance of anesthesia, fractional inspired oxygen (FIO2) of 50% in air with desflurane was used with a fresh gas flow of 4 L/min. All patients were monitored with electrocardiography and for peripheral oxygen saturation (SpO2), end-tidal carbon dioxide (ET), heart rate (HR), noninvasive mean blood pressure (MBP), and bispectral index (BIS). Bilateral TAP blocks were performed under ultrasound guidance to Group 1 patients. The BIS value was maintained at between 40 and 50 during the surgery. The Dion formula was used to calculate consumption of desflurane for each patient. There was no difference between the groups with respect to demographic characteristics of the patients. Duration of anesthesia, surgery time, and dosage of fentanyl were similar in the 2 groups. However, the cost and consumption of desflurane was significantly lower in Group 1. Total anesthesia consumption was lower and the cost-effectiveness of anesthesia was better in TAP block patients with general anesthesia than in non-TAP block patients undergoing laparoscopic cholecystectomy.

    Full Text Available ABSTRACT: This paper pretends to demonstrate the effect of the combination of transversus abdominis plane block (TAP block and Serratus plane block (SP block techniques in analgesia of 4 dogs undergoing total unilateral mastectomy. Dogs were premedicated with methadone (0.5mg.kg-1 intramuscularly. Anesthesia was induced with propofol (6mg.kg-1 and midazolam (0.3mg.kg-1 and maintained with isoflurane. SP and TAP block were performed unilaterally using ultrasound by the injection of bupivacaine 0.25% (0.3mL kg-1 diluted with NaCl solution 1:1. Heart rate (HR, respiratory rate (f, non-invasive arterial pressure, esophageal temperature (T, oxygen saturation (SpO2 and electrocardiogram were monitored continuously. Animals were monitored for two and four hours after extubation for pain by using the Canine Acute Pain Scale from Colorado State University. Two hours after extubation, tramadol (4mg.kg-1 and dipyrone (25mg.kg-1 was administered to all dogs. It was not observed any alteration on cardiac rhythm. HR, f, T and mean arterial pressure remained below the preincisional values for all dogs. No dog required intraoperative rescue analgesia. Recovery from anesthesia was without any complication. All animals scored 0 (0/5 at pain scale, two and four hours after extubation and none of them expressed concern over the surgical wound. Dogs were able to walk before two hours after extubation. The combination of both techniques is effective in anesthetic blocking the thoracic and abdominal walls and it is suggested both may be included in the multimodal analgesia protocols for this type of surgery.

    Side effects associated with use of postoperative narcotics for pain control can delay recovery after abdominally based microsurgical breast reconstruction. The authors evaluated a nonnarcotic pain control regimen in conjunction with bilateral transversus abdominis plane blocks on facilitating early hospital discharge. A retrospective analysis was performed of consecutive patients who underwent breast reconstruction using abdominally based free flaps, with or without being included in a nonnarcotic protocol using intraoperative transversus abdominis plane blockade. During this period, the use of locoregional analgesia evolved from none (control), to continuous bupivacaine infusion transversus abdominis plane and catheters, to single-dose transversus abdominis plane blockade with liposomal bupivacaine solution. Demographic factors, length of stay, inpatient opioid consumption, and complications were reported for all three groups. One hundred twenty-eight consecutive patients (182 flaps) were identified. Forty patients (62 flaps) were in the infusion-liposomal bupivacaine group, 48 (66 flaps) were in the single-dose blockade-catheter group, and 40 (54 flaps) were in the control group. The infusion-liposomal bupivacaine patients had a significantly shorter hospital stay compared with the single-dose blockade-catheter group (2.65 ± 0.66 versus 3.52 ± 0.92 days; p plane blocks performed with single injections of liposomal bupivacaine help facilitate early hospital discharge after abdominally based microsurgical breast reconstruction. A trend toward consistent discharge by postoperative day 2 was seen. This could result in significant cost savings for health care systems. Therapeutic, III.

    To assess the effect of bilateral ultrasound-guided transversus abdominis plane block with ropivacaine compared with placebo as part of a multimodal analgesic regimen. A randomized, double-blind, placebo-controlled trial following the CONSORT criteria. Hvidovre University Hospital. Forty-six women scheduled for total abdominal hysterectomy. Women received either ropivacaine 0.75%, 20 mL (n = 24) or 0.9% saline, 20 mL (n = 24) in the transversus abdominis plane on each side. Primary outcome was the 24-h postoperative morphine consumption. Secondary outcomes were pain scores at rest and during coughing, postoperative nausea and vomiting at 1, 2, 4, 6, 8, and 24 h, and time to first mobilization. There was no difference in the mean 24-h postoperative morphine consumption between the two groups (p = 0.733). The ropivacaine group had significantly lower median pain scores at 1 h (p = 0.008) and 2 h (p = 0.027) postoperatively at rest and at 8 h (p = 0.028) during coughing. There was no significant difference in other secondary outcomes. There was no reduction in 24-h morphine consumption when using an ultrasound-guided transversus abdominis plane block in women undergoing total abdominal hysterectomy. As part of a multimodal regimen the transversus abdominis plane block showed some effect on pain scores at rest only in the early postoperative period. © 2014 Nordic Federation of Societies of Obstetrics and Gynecology.

    Rupture of the extraocular muscle in the absence of significant injury to the eyeball and adnexa is uncommon. The authors report a case of blunt trauma of the eyeball associated with an inferior oblique muscle and an inferior rectus muscle rupture. A 55-year-old man slipped and fell down hitting his eye on an extended windshield wiper blade. Although he had treatment in the emergency room, he complained of diplopia in the primary position 1 day postoperatively. After noticing ruptures of the inferior oblique muscle and an inferior rectus muscle during exploratory surgery, the authors carefully repaired it. Diplopia in the primary position had disappeared within 1 month after the operation and by 6 months postoperatively. The movement of the eye had almost completely recovered.

Aims: The aim is to compare the visual analog scale (VAS of pain and the requirement of rescue analgesia postoperatively in patients undergoing various abdominal surgeries (open and laparoscopic where TAP block was given for postoperative analgesia and was compared with patients who received pain relief according to the institutional protocol. Settings and Design: Retrospective observational study conducted in a tertiary care hospital. Subjects and Methods: Retrospective data from anesthesia records of patients, who underwent abdominal surgeries from January 2016 to December 2016, were analyzed and were divided into two groups. Group A (n = 250 consisted of patients who received the conventional standard postoperative analgesia protocol of the department of anesthesia. Group B (n = 136 consisted of patients who were administered TAP block postsurgery for the postoperative analgesia by the trained anesthesiologist. Primary outcome considered was (i average VAS at 02, 06, 12, and 24 h and (ii average opioid/nonsteroidal anti-inflammatory drug consumption at 24 h postoperatively. Secondary outcome considered was time to first rescue analgesia. Statistical Analysis: All parametric data were analyzed using unpaired t-test. Data are expressed as the mean ± standard deviation. A SPSS version 17 (SPSS Inc., Chicago, IL, USA was used for statistical analysis. Results: Average pain scores (VAS were lower in Group B as compared to Group A in all subcategories of surgery postoperatively. Patients given TAP block (Group B required less rescue analgesia in the postoperative period with time to first rescue analgesia being prolonged. Conclusions: On the basis of our retrospective study, we suggest that TAP block can be utilized as a part of multimodal analgesia regimen for

    Conventional perioperative analgesic modalities (e.g. opioids, epidural analgesia) have their own drawbacks, which limit their clinical application. This study investigated the opioid-sparing effectsof the oblique subcostal transversus abdominis plane (OSTAP) blockade with ropivacaine for the patients undergoing open liver resection with a Mercedes incision. 126 patients who were scheduled for open liver resection were enrolled in this study. Patients were randomly assigned to receive bilateral ultrasound-guided OSTAPblocks with either 0.375% ropivacaine (groupT) or 0.9% isotonic saline (group C). Both groups also received intravenous patient-controlled analgesia and intravenous 40 mg parecoxib every 12 h for a total of 3 days. Preoperative and intraoperative parameters, plus intraoperative and postoperative cumulative sufentanil consumption, were recorded. 70 patients were enrolled in the study finally. There were no significant differences between the two groups with respect to preoperative parameters, and surgical and anesthetic characteristics. The intraoperative sufentanil use, cumulative sufentanil consumption at 5 min after extubation, 2 h, 4 h,12 h and 24 h after operation in group T was significantly less than that in group C (P = 0.001, 0.001, 0.000, 0.000, 0.001 and 0.044, respectively). Compared with group C, postoperative NRS pain scores at rest were significantly lower at 2 h and 4 h postoperatively in group T (P = 0.04and 0.02, respectively); NRS scores at the time of coughing were also significantly lower in group T than in group C at all time points except 5 min after extubation (all P < 0.001). Furthermore, compared with group C, the number of intraoperative vasodilator use, the extubation time and the incidence of nausea was reduced in group T. Ultrasound-guided OSTAP block with ropivacaine can significantly decrease the perioperative cumulative dosage of analgesics and improve analgesic effect without obvious side

    BACKGROUND: Transversus abdominis plane (TAP) block is an alternative to spinal morphine for analgesia after Caesarean section but there are few data on its comparative efficacy. We compared the analgesic efficacy of the TAP block with and without spinal morphine after Caesarean section in a prospective, randomized, double-blinded placebo-controlled trial. METHODS: Eighty patients were randomized to one of four groups to receive (in addition to spinal anaesthesia) either spinal morphine 100 microg (S(M)) or saline (S(S)) and a postoperative bilateral TAP block with either bupivacaine (T(LA)) 2 mg kg(-1) or saline (T(S)). RESULTS: Pain on movement and early morphine consumption were lowest in groups receiving spinal morphine and was not improved by TAP block. The rank order of median pain scores on movement at 6 h was: S(M)T(LA) (20 mm)

    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.

    Regional analgesic techniques are commonly used in pediatric urology. Ultrasound guided transversus abdominis plane block has recently gained popularity. However, there is a paucity of information supporting a benefit over regional field infiltration. We present a parallel group, randomized, controlled trial evaluating ultrasound guided transversus abdominis plane block superiority over surgeon delivered regional field infiltration for children undergoing open pyeloplasty at a tertiary referral center. Following ethics board approval and registration, children 0 to 6 years old were recruited and randomized to undergo perioperative transversus abdominis plane block or regional field infiltration for early post-pyeloplasty pain control. General anesthetic delivery, surgical technique and postoperative analgesics were standardized. A blinded assessor regularly captured pain scores in the recovery room using the FLACC (Face, Legs, Activity, Cry, Consolability) scale. The primary outcome was the need for rescue morphine administration based on a FLACC score of 3 or higher. Two pediatric urologists performed 57 pyeloplasties during a 2.5-year period, enrolling 32 children (16 in each group, balanced for age and weight). There were statistically significant differences in the number of children requiring rescue morphine administration (13 of 16 receiving transversus abdominis plane block and 6 of 16 receiving regional field infiltration, p = 0.011), mean ± SD total morphine consumption (0.066 ± 0.051 vs 0.028 ± 0.040 mg/kg, p = 0.021) and mean ± SD pain scores (5 ± 5 vs 2 ± 3, p = 0.043) in the recovery room, in favor of surgeon administered regional field infiltration. No local anesthetic specific adverse events were noted. Ultrasound guided transversus abdominis plane block is not superior to regional field infiltration with bupivacaine as a strategy to minimize early opioid requirements following open pyeloplasty in children. Instead, our data suggest that

    Muscle injury is the most common injury during sport practice. It represents 31% of all lesions in soccer, 16% in track and field, 10.4% in rugby, 17.7% in basketball, and between 22% and 46% in American football. The cicatrization with the formation of fibrotic tissue can compromise the muscle function, resulting in a challenging problem for orthopedics. Although conservative treatment presents adequate functional results in the majority of the athletes who have muscle injury, the consequences of treatment failure can be dramatic, possibly compromising the return to sport practice. The biarticular muscles with prevalence of type II muscle fibers, which are submitted to excentric contraction, present higher lesion risk. The quadriceps femoris is one example. The femoris rectus is the quadriceps femoris muscle most frequently involved in stretching injuries. The rupture occurs in the acceleration phase of running, jump, ball kicking, or in contraction against resistance. Although the conservative treatment shows good results, it is common that the patient has lower muscle strength, difficulty in return to sports, and a permanent and visible gap. Surgical treatment can be an option for a more efficient return to sports.

    Transcranial magnetic stimulation (TMS) involves non-invasive magnetic stimulation of the brain, and can be used to explore the corticomotor excitability and motor representations of skeletal muscles. However there is a lack of motor mapping studies in the lower limb and few conducted in healthy cohorts. The cortical motor representations of muscles can vary between individuals in terms of center position and area despite having a general localized region within the motor cortex. It is important to characterize the normal range for these variables in healthy cohorts to be able to evaluate changes in clinical populations. TMS was used in this cross-sectional study to assess the active motor threshold (AMT) and cortical representation area for rectus femoris in 15 healthy individuals (11M/4F 27.3±5.9years). No differences were found between hemispheres (Left vs. Right P=0.130) for AMT. In terms of y-axis center position no differences were found between hemispheres (Left vs. Right P=0.539), or for the x-axis center position (Left vs. Right P=0.076). Similarly, no differences in calculated area of the motor representation were found (Left vs. Right P=0.699) indicating symmetry between hemispheres. Copyright © 2016 Elsevier Ltd.

However, when epidural analgesia is contraindicated or unwanted, the administration of opioids is the usual means used to relieve pain. Various regional analgesia techniques used in conjunction with systemic analgesia have been reported to reduce the cumulative postoperative opioid consumption and opioid-induced side effects. The objective of this trial was to assess the effectiveness of transversus abdominis plane block and paravertebral block in women undergoing major gynecological surgery.Methods: We analyzed 58 patients scheduled for a midline vertical laparatomy due to gynecological cancer. They were all equipped with a patient-controlled postoperative analgesia pump that delivered ketobemidon. In addition, some patients were randomized to receive either a bilateral transversus abdominis plane block (n = 19 or a bilateral paravertebral block at the level of Th10 (n = 19. Both blocks were performed preoperatively as a single injection of bupivacaine.Results: Cumulative ketobemidon consumption, postoperative pain scores at rest and while coughing, and postoperative nausea and vomiting scores were assessed by a blinded observer at 2, 4, 6, 24, and 48 hours postoperatively. Both blocks were associated with significant reductions in opioid consumption and pain scores throughout the study period compared with the control patients. Postoperative nausea and vomiting scores were low in all groups, but during the early postoperative period more control group patients needed antiemetics

    To analyze the presence of referred pain elicited by manual examination of the lateral rectus muscle in patients with chronic tension-type headache (CTTH). A case-control blinded study. It has been found previously that the manual examination of the superior oblique muscle can elicit referred pain to the head in some patients with migraine or tension-type headache. However, a referred pain from other extraocular muscles has not been investigated. Fifteen patients with CTTH and 15 healthy subjects without headache history were included. A blinded assessor performed a manual examination focused on the search for myofascial trigger points (TrPs) in the right and left lateral rectus muscles. TrP diagnosis was made when there was referred pain evoked by maintained pressure on the lateral corner of the orbit (anatomical projection of the lateral rectus muscle) for 20 seconds, and increased referred pain while the subject maintained a medial gaze on the corresponding side (active stretching of the muscle) for 15 seconds. On each side, a 10-point numerical pain rate scale was used to assess the intensity of referred pain at both stages of the examination. Ten patients with CTTH (66.6%) had referred pain that satisfied TrPs diagnostic criteria, while only one healthy control (0.07%) reported referred pain upon the examination of the lateral rectus muscles (P < 0.001). The elicited referred pain was perceived as a deep ache located at the supraorbital region or the homolateral forehead. Pain was evoked on both sides in all subjects with TrPs, with no difference in pain intensity between the right and the left. The average pain intensity was significantly greater in the patient group (P < 0.001). All CTTH patients with referred pain recognized it as the frontal pain that they usually experienced during their headache attacks, which was consistent with active TrPs. In some patients with CTTH, the manual examination of lateral rectus muscle TrPs elicits a referred pain that

    The application of ultrasound-guided transversus abdominis plane (TAP) block in paediatric population is gaining popularity among anaesthetists. We present a case series of ultrasound-guided TAP block in ten neonate and infants undergoing colostomy and reversal of stoma. Classical TAP as described by Hebbard was carried out and a maximum dosage of 1ml/kg of 0.25% levobupivacaine was injected. Pain score was assessed using Neonatal Infant Pain Scale for 24 hours. In all patients, the block was successful with minimal hemodynamic changes intraoperatively and no additional systemic analgesia was needed intraoperative and immediate postoperatively. Ultrasound-guided TAP block has an important role in providing safe and effective analgesia for colostomy creation and reversal of stoma surgeries in paediatric population.

    Full Text Available ABSTRACT We describe the preliminary national experience and the early results of the use of robotic surgery to perform the posterior separation of abdominal wall components by the Transversus Abdominis Release (TAR technique for the correction of complex defects of the abdominal wall. We performed the procedures between 04/2/2015 and 06/15/2015 and the follow-up time was up to six months, with a minimum of two months. The mean surgical time was five hours and 40 minutes. Two patients required laparoscopic re-intervention, since one developed hernia by peritoneal migration of the mesh and one had mesh extrusion. The procedure proved to be technically feasible, with a still long surgical time. Considering the potential advantages of robotic surgery and those related to TAR and the results obtained when these two techniques are associated, we conclude that they seem to be a good option for the correction of complex abdominal wall defects.

The utilization of ultrasound has greatly augmented the success rate of this block and additionally avoiding complications. The aim of our study was to gauge the analgesic efficacy of ultrasound-guided TAP block in patients undergoing unilateral inguinal hernia repair. Materials and methods: Sixty patients scheduled for elective inguinal hernia repair were selected for the study. At the end of the surgical procedure, they were randomly divided into two groups. Ultrasound-guided TAP block was performed with 20 mL of ropivacaine 0.2% (group A or normal saline (group B. Visual analog scale (VAS scores were used to assess pain. Paracetamol was given if VAS >3 and tramadol was used when VAS >6. Patients were monitored for VAS scores and total analgesic consumption for the 24-hour period. Results: The TAP block with ropivacaine (group A reduced VAS scores at 4, 6, and 12 hours. There was no distinction in VAS scores at 0, 2, and 24 hours between the two groups. The duration of analgesia for TAP block with ropivacaine lasted for 390 minutes. Total analgesics consumption was also significantly reduced in group A than group B. No complication was reported to TAP block in both the groups. Conclusion: The ultrasound-guided TAP block provides good postoperative analgesia, reduces analgesic requirements, and provides good VAS scores with fewer complications following inguinal hernia surgery.

    To elucidate the intramuscular distribution and branching patterns of the abducens nerve in the lateral rectus (LR) muscle so as to provide anatomical confirmation of the presence of compartmentalization, including for use in clinical applications such as botulinum toxin injections. Thirty whole-mount human cadaver specimens were dissected and then Sihler's stain was applied. The basic dimensions of the LR and its intramuscular nerve distribution were investigated. The distances from the muscle insertion to the point at which the abducens nerve enters the LR and to the terminal nerve plexus were also measured. The LR was 46.0 mm long. The abducens nerve enters the muscle on the posterior one-third of the LR and then typically divides into a few branches (average of 1.8). This supports a segregated abducens nerve selectively innervating compartments of the LR. The intramuscular nerve distribution showed a Y-shaped ramification with root-like arborization. The intramuscular nerve course finished around the middle of the LR (24.8 mm posterior to the insertion point) to form the terminal nerve plexus. This region should be considered the optimal target site for botulinum toxin injections. We have also identified the presence of an overlapping zone and communicating nerve branches between the neighboring LR compartments. Sihler's staining is a useful technique for visualizing the entire nerve network of the LR. Improving the knowledge of the nerve distribution patterns is important not only for researchers but also clinicians to understand the functions of the LR and the diverse pathophysiology of strabismus.

    Full Text Available AIM:To analyze the surgical results of a slipped medial rectus muscle (MRM after hang back recession surgery for esotropia.METHODS:Twenty-one patients who underwent re-exploration for diagnosed slipped muscle after hang back recession surgery were included in this retrospective study. Dynamic magnetic resonance imaging was performed to identify the location of the slipped muscle. Ocular motility was evaluated with assessment with prism and cover test in gaze at cardinal positions. The operations were performed by the same consultant. Intraoperative forced duction test was performed under general anesthesia. The empty sheath of the slipped MRM was resected and the muscle was advanced to the original insertion site in all patients.RESULTS:The average age of 21 patients who hadconsecutive exotropia with a slipped MRM at the time of presentation was 17.4±5.4y (5-50y. The average duration between the first operation and the diagnosis of the slipped muscle was 25mo (12 to 36mo. The mean follow up after the corrective surgery was 28mo. The mean preoperative adduction limitation in the field of action of the slipped muscle was -2.26 (ranging from -1 to -4. All patients had full adduction postoperatively.CONCLUSION:The diagnosis of the slipped muscle should be confirmed during the strabismus surgery. The slipped muscle may be caused due to insufficient suture and excessive rubbing of the eye. When divergent strabismus is observed after the recession of the MRM, a slipped muscle should be considered in the differential diagnosis.

    The aims of this study were to elucidate the detailed anatomy of the abducens nerve in the lateral rectus muscle (LRM) and the intramuscular innervation pattern using Sihler staining. In this cohort study, 32 eyes of 16 cadavers were assessed. Dissection was performed from the LRM origin to its insertion. The following distances were measured: from LRM insertion to the bifurcation point of the abducens nerve, from LRM insertion to the entry site of the superior branch or inferior branch, from the upper border of the LRM to the entry site of the superior branch, from the lower border of LRM to the entry site of inferior branch, and the widths of the main trunk and superior and inferior branches. The single trunk of the abducens nerve divided into two branches 37 mm from insertion of the LRM, and 22 of 32 (68.8%) orbits showed only two superior and inferior branches with no subdivision. The superior branch entered the LRM more anteriorly (P = 0.037) and the superior branch was thinner than the inferior branch (P = 0.040). The most distally located intramuscular nerve ending was observed at 52.9 ± 3.5% of the length of each muscle. Non-overlap between the superior and inferior intramuscular arborization of the nerve was detected in 27 of 32 cases (84.4%). Five cases (15.6%) showed definite overlap of the superior and inferior zones. This study revealed the detailed anatomy of the abducens nerve in the LRM and provides helpful information to understand abducens nerve palsy. Clin.

    This study aimed to compare the efficacy of onabotulinum toxin A (onabot) injection into the rectus femoris muscle with that of placebo in the treatment of hemiplegic stroke patients presenting with stiff-knee gait. Twenty-five chronic hemiparetic stroke patients presenting with a stiff-knee gait were included in this study. Fifteen patients received 100-125 U of onabot, and 10 patients received placebo into the rectus femoris muscle. Three-dimensional gait analysis, energy expenditure, 10-m and 6-min walk tests, and spasticity level of the rectus femoris were evaluated at baseline and 2 mos posttreatment. The mean age of patients who received onabot was 53.86 ± 14.74 yrs and of those who received placebo was 59.00 ± 8.11 yrs. At study onset, groups were similar with respect to all parameters (P > 0.05). We observed significant improvement in knee flexion (7 degrees average) during swing and a reduction in energy cost of 0.8-J/kg per meter response to injection of 100-125 U of onabot into the rectus femoris muscle. Onabot treatment significantly reduced muscle tone and improved knee kinematics, energy expenditure during walking, and functional assessments at 2 mos (P application of onabot into the rectus femoris muscle in stroke patients who presented with stiff-knee gait may be a treatment option to provide independent, safe, and less tiring ambulation.

    Although individual reports suggest that baseline morphometry or activity of transversus abdominis or lumbar multifidus predict clinical outcome of low back pain (LBP), a related systematic review is unavailable. Therefore, this review summarized evidence regarding the predictive value of these muscular characteristics. Candidate publications were identified from 6 electronic medical databases. After review, 5 cohort studies were included. Although this review intended to encompass studies using different muscle assessment methods, all included studies coincidentally used ultrasound imaging. No research investigated the relation between static morphometry and clinical outcomes. Evidence synthesis showed limited evidence supporting poor baseline transversus abdominis contraction thickness ratio as a treatment effect modifier favoring motor control exercise. Limited evidence supported that high baseline transversus abdominis lateral slide was associated with higher pain intensity after various exercise interventions at 1-year follow-up. However, there was limited evidence for the absence of relation between the contraction thickness ratio of transversus abdominis or anticipatory onset of lateral abdominal muscles at baseline and the short- or long-term LBP intensity after exercise interventions. There was conflicting evidence for a relation between baseline percent thickness change of lumbar multifidus during contraction and the clinical outcomes of patients after various conservative treatments. Given study heterogeneity, the small number of included studies and the inability of conventional greyscale B-mode ultrasound imaging to measure muscle activity, our findings should be interpreted with caution. Further large-scale prospective studies that use appropriate technology (ie, electromyography to assess muscle activity) should be conducted to investigate the predictive value of morphometry or activity of these muscles with respect to LBP-related outcomes measures

    Background. It is important to assess the activity of Graves' ophthalmopathy (GO) for planning optimal treatment strategy. Dynamic contrast-enhanced MR imaging (DCE-MRI) is a technique for assessment of microcirculation status. The correlation between disease activity and the microcirculation characteristics of extraocular muscles (EOMs) has been demonstrated in GO. Purpose. To investigate the changes of rectus EOMs in patients with active vs. inactive GO using DCE-MRI, and to evaluate the value of DCE-MRI in assessing the activity of GO. Material and Methods. Rectus EOMs of 20 healthy controls, 18 patients with active GO, and 16 patients with inactive GO were studied. The signal intensity (SI) of rectus EOMs on T 2 W images was evaluated. Regions of interest were placed on each rectus on DCE-MRI images. The DCE-MRI parameters including time to peak enhancement (T peak ), enhancement ratio (ER), and wash-out ratio (WR) were calculated. Results. There were significant differences in SI and T peak , ER and WR values among the three groups (P = 0.000). However, there was no significant difference in SI between the active and inactive groups (P = 0.07). Tpeak values of each rectus were significantly increased in inactive group compared with the active group (P peak ), maximum ER (maxER) and maximum WR (maxWR) (P peak , maxER and maxWR were 156.98s, 1.31 and 13.50% respectively, giving positive predictive values of 68.00%, 88.90%, and 94.44% for the assessment of disease activity. Conclusion. DCE-MRI could demonstrate the micro circulatory changes of rectus EOMs in both active and inactive GO, and this MRI method is a useful tool in differentiating active from inactive GO

    Fractal dimension was demonstrated to be able to characterize the complexity of biological signals. The EMG time series are well known to have a complex behavior and some other studies already tried to characterize these signals by their fractal dimension. This paper is aimed at studying the correlation between the fractal dimension of surface EMG signal recorded over Rectus Femoris muscles during a vertical jump and the height reached in that jump. Healthy subjects performed vertical jumps at different heights. Surface EMG from Rectus Femoris was recorded and the height of each jump was measured by an optoelectronic motion capture system. Fractal dimension of sEMG was computed and the correlation between fractal dimension and eight of the jump was studied. Linear regression analysis showed a very high correlation coefficient between the fractal dimension and the height of the jump for all the subjects. The results of this study show that the fractal dimension is able to characterize the EMG signal and it can be related to the performance of the jump. Fractal dimension is therefore an useful tool for EMG interpretation

    Due to the importance of pain control after abdominal surgery, several methods such as transversus abdominis plane (TAP) block are used to reduce the pain after surgery. TAP blocks can be performed using various ultrasound-guided approaches. Two important approaches to do this are ultrasound-guided lateral and posterior approaches. This study aimed to compare the two approaches of ultrasound-guided lateral and posterior TAP blocks to control pain after cesarean section. In this double-blind clinical trial study, 76 patients scheduled for elective cesarean section were selected and randomly divided into two groups of 38 and underwent spinal anesthesia. For pain management after the surgery, one group underwent lateral TAP block and the other group underwent posterior TAP block using 20cc of ropivacaine 0.2% on both sides. Pain intensity was evaluated based on Numerical Analog Scale (NAS) at rest and when coughing, 2, 4, 6, 12, 24 and 36 hours after surgery. The pain at rest in the posterior group at all hours post surgery was lower than the lateral group, especially at 6, 12 and 24 hours after the surgery and the difference was statistically significant ( p =0.03, p block compared with the lateral TAP block was more effective in pain control after cesarean section.

    The role of so-called local muscle system in motor control of the lower back and pelvis is a subject of ongoing debate. Prevailing beliefs in stabilizing function of this system were recently challenged. This study investigated the impact of in vitro simulated force of transversely oriented fibres of the transversus abdominis muscle (a part of the local system) on flexibility of the sacroiliac joint during asymmetric moment application to the pelvis. In 8 embalmed specimens an incremental moment was applied in the sagittal plane to one innominate with respect to the fixed contralateral innominate. Ranges of motion of the sacroiliac joint were recorded using the Vicon Motion Capture System. Load-deformation curves were plotted and flexibility of the sacroiliac joint was calculated separately for anterior and posterior rotations of the innominate, with and without simulated muscle force. Flexibility of the sacroiliac joint was significantly bigger during anterior rotation of the innominate, as compared to posterior rotation (Anova Psacroiliac joint was demonstrated. Earlier hypotheses suggesting a stiffening influence of this muscle on the pelvis cannot be confirmed. Consistent with previous findings smaller flexibility of the joint recorded during posterior rotation of the innominate may be of clinical importance for physio- and manual therapists. However, major limitations of the study should be acknowledged: in vitro conditions and simulation of only solitary muscle force. Copyright © 2015 Elsevier Ltd. All rights reserved.

    2012-01-01

    Full Text Available Background: Pain experienced following laparoscopic cholecystectomy is largely contributed by the anterior abdominal wall incisions. This study investigated whether subcostal transversus abdominis (STA block was superior to traditional port-site infiltration of local anesthetic in reducing postoperative pain, opioid consumption, and time for recovery. Materials and Methods: Forty-three patients presenting for day case laparoscopic cholecystectomy were randomly allocated to receive either an ultrasound-guided STA block (n = 21 or port-site infiltration of local anesthetic (n = 22. Visual analog pain scores were measured at 1 and 4 h postoperatively to assess pain severity, and opioid requirement was measured in recovery and up to 8 h postoperatively. The time to discharge from recovery was recorded. Results: STA block resulted in a significant reduction in serial visual pain analog score values and significantly reduced the fentanyl requirement in recovery by >35% compared to the group that received local port-site infiltration (median 0.9 vs. 1.5 ΅cg/kg. Furthermore, STA block was associated with nearly a 50% reduction in overall 8-h equivalent morphine consumption (median 10 mg vs. 19 mg. In addition, STA block significantly reduced median time to discharge from recovery from 110 to 65 min. Conclusion: The results suggest that STA block provides superior postoperative analgesia and reduces opioid requirement following laparoscopic cholecystectomy. It may also improve theater efficiency by reducing time to discharge from the recovery unit.

    Transversus abdominis plane (TAP) blocks are increasingly being utilized in microvascular breast reconstruction. The implications of TAP blocks on specific reconstructive, patient and institutional outcomes remain to be fully elucidated. Patients undergoing abdominally-based microvascular breast reconstruction from 2015-2017 were reviewed. Length of stay, complications, narcotic consumption, donor-site pain and hospital expenses were compared between patients that did and those that did not receive TAP blocks with liposomal bupivacaine. Outcomes were subsequently compared in patients with elevated body mass index (BMI). Fifty patients (43.9%) received TAP blocks (27 [54.0%] under ultrasound guidance) and 64 patients (56.1%) did not. Patients with TAP blocks had significantly decreased oral and total narcotic consumption (p=0.0001 and pconsumption and postoperative pain compared to patients without TAP blocks. Patients with BMIconsumption or length of stay between the TAP versus no TAP block groups. TAP blocks with liposomal bupivacaine significantly reduce oral and total postoperative narcotic consumption as well as donor-site pain in all patients after abdominally-based microvascular breast reconstruction without increasing hospital expenses. TAP blocks additionally significantly decrease length of stay in patients with BMI≥25.

    Injection of local anesthetic into the transversus abdominis plane (TAP block) decreases systemic morphine requirements after abdominal surgery. We compared intraoperative surgeon-administered TAP block (surgical TAP) to anesthesiologist-administered transcutaneous ultrasound-guided TAP block (conventional TAP) for post-cesarean analgesia. We hypothesized that surgical TAP blocks would take less time to perform than conventional TAP blocks. We performed a randomized trial, recruiting 41 women undergoing cesarean delivery under neuraxial anesthesia, assigning them to either surgical TAP block (n=20) or conventional TAP block (n=21). Time taken to perform the block was the primary outcome, while postoperative pain scores and 24-hour opioid requirements were secondary outcomes. Student's t-test was used to compare block time and Kruskal-Wallis test opioid consumption and pain-scores. Time taken to perform the block (2.4 vs 12.1 min, P consumption (P=0.17) and postoperative pain scores at 4, 8, 24 and 48 h were not significantly different between the groups. Surgical TAP blocks are feasible and less time consuming than conventional TAP blocks, while providing comparable analgesia after cesarean delivery. Copyright © 2018 Elsevier Ltd.

    Full Text Available Objectives: To investigate the analgesic effect of a subcostal-posterior transversus abdominis plane (TAP block combination following laparoscopic sleeve gastrectomy. Methods: This study was conducted at Fatih Sultan Mehmet Educational and Research Hospital, Istanbul, Turkey, between March 2014 and June 2015. A total of 40 patients with a body mass index of 40-60 kg/m2 scheduled for laparoscopic sleeve gastrectomy were randomly allocated into 2 groups. Patients in Group I (n=20 received a bilateral subcostal TAP block, and patients in Group II (n=20 received a bilateral subcostal and posterior TAP block. Pain intensity was assessed at rest and during coughing using the visual analog scale (VAS prior to and at various time points after TAP block (0 min, 30 min, 2 hours, 4 hours, 6 hours, 12 hours, and 24 hours. Morphine consumption over 24 hours and time to first morphine requirement were recorded. Results: There was no difference in VAS scores between groups. Morphine consumption was 6.78±5.95 mg in Group I, and 7.28±5.95 mg in Group II (p=0.795. Time to first morphine requirement was 267.22±303.84 min for Group I, and 207.80±209.81 min for Group II (p=0.154. Conclusions: Subcostal-posterior TAP block provided equivalent analgesia to subcostal TAP block alone following laparoscopic sleeve gastrectomy.

    To evaluate the analgesic effect of transversus abdominis plane (TAP) block administered before varicocele surgery. This study was completed at the Faculty of Medicine, Çanakkale Onsekiz Mart University, Çanakkale, Turkey, between January 2011 and April 2013. In a prospective, double blind, randomized, placebo controlled clinical study, 40 male patients scheduled for elective varicocele operations were randomized to group T (treatment group) or group C (controls). After receiving general anesthesia, group T received a TAP block using 20 mL 0.25% bupivacaine on the operation side, whereas group C received a control block using 20 mL 0.9% Sodium chloride. During the first 24 hours after surgery, the patient pain was evaluated using the visual analogue scale (VAS) at rest and while coughing. Postoperative patient controlled analgesia morphine consumption, VAS scores, and side effects were recorded. Of 34 patients, Group T (n=18) had significantly lower VAS pain scores than Group C (n=16) both at rest and while coughing. The total morphine consumed was  lower (7.7 ± 4.0) versus 21.6 ± 12.4 mg, p less than 0.001) in the 24 hours after surgery. As part of a multimodal analgesic regime after varicocelectomy surgery, morphine consumption and VAS pain scores were significantly lower among those receiving 20 mL 0.25% bupivacaine administered for a TAP block than among controls.

    Transversus abdominis plane (TAP) block is a locoregional anaesthesia technique of growing interest in abdominal surgery. However, its efficacy following laparoscopic colorectal surgery is still debated. This meta-analysis aimed to assess the efficacy of TAP block after laparoscopic colorectal surgery. All comparative studies focusing on TAP block after laparoscopic colorectal surgery have been systematically identified through the MEDLINE database, reviewed and included. Meta-analysis was performed according to the Mantel-Haenszel method for random effects. End-points included postoperative opioid consumption, morbidity, time to first bowel movement and length of hospital stay. A total of 13 studies, including 7 randomized controlled trials, were included, comprising a total of 600 patients who underwent laparoscopic colorectal surgery with TAP block, compared with 762 patients without TAP block. Meta-analysis of these studies showed that TAP block was associated with a significantly reduced postoperative opioid consumption on the first day after surgery [weighted mean difference (WMD) -14.54 (-25.14; -3.94); P = 0.007] and a significantly shorter time to first bowel movement [WMD -0.53 (-0.61; -0.44); P plane (TAP) block in laparoscopic colorectal surgery improves postoperative opioid consumption and recovery of postoperative digestive function without any significant drawback.

    We conducted a single-centre, prospective randomised clinical trial to investigate the analgesic efficacy of transversus abdominis plane (TAP) block in adult patients undergoing laparoscopic appendicectomy. Patients undergoing urgent laparoscopic appendicectomy under general anaesthesia alone (control group) and general anaesthesia supplemented by TAP block (TAP intervention group) were compared. All patients received a multimodal analgesia regime, which included postoperative morphine via a patient-controlled analgesia device. The primary endpoints were morphine consumption at 12 hours and 24 hours postoperatively. Secondary endpoints included pain scores, incidence of nausea and vomiting, and time to hospital discharge. A total of 58 patients were recruited, with 29 patients in each group. Mean postoperative morphine consumption at 12 hours (control group: 11.45 ± 7.64 mg, TAP intervention group: 9.79 ± 8.09 mg; p = 0.4264) and 24 hours (control group: 13.38 ± 8.72 mg, TAP intervention group: 11.31 ± 8.66 mg; p = 0.3686) for the control and TAP intervention groups were not statistically different. Secondary outcomes were also not different between the two groups. Length of stay in the post-anaesthesia care unit was significantly shorter for the TAP intervention group, with a trend toward faster hospital discharge being observed. TAP block, a regional anaesthetic procedure performed immediately prior to skin incision for laparoscopic appendicectomy, did not significantly improve postoperative analgesia outcomes.

    Radical cystectomy (RC) is a morbid procedure with frequent complications that may benefit from implementation of an enhanced recovery after surgery (ERAS) protocol. To examine the benefits of a multimodal analgesic plan that uses continuous transversus abdominis plane (TAP) blockade as part of an ERAS protocol after RC. A retrospective comparison of consecutive patients undergoing RC over a 4-year period was conducted. Patients were designated as having surgery either before or after implementation of an ERAS protocol. A major component of the ERAS protocol was a multi-modal analgesia plan with TAP blockade. Patient demographics, comorbidities, operative details, and outcomes, including days to flatus, bowel movement (BM), narcotic usage, and length of stay (LOS) were compared. In total, 171 patients were included: 100 pre-ERAS and 71 ERAS. There were no differences in age, smoking status, operative approach, or diversion type. The patients in the ERAS cohort were less likely to be male, had a higher median BMI, and more likely to have received neoadjuvant chemotherapy. Total and early postoperative narcotic use were lower in the ERAS cohort: 89 vs. 336 mg ( p  RC pain management.

    A case of complex microsurgical reconstruction of the dorsum of the foot, including tendon transfer following tumor resection, in a 15-week-old male infant is presented. After birth, a 5.5 x 4 cm large tumor was observed on the dorsum of the right foot. Biopsy showed a congenital malignant fibro sarcoma. After initial chemotherapy a radical excision of the tumor at the age of 14 weeks was followed. To cover the defect a musculocutaneous latissimus dorsi flap was taken, the cutaneous part being large enough to cover the defect. Extensor tendons were reconstructed with free tendon transplants. Amputation is usually indicated in these cases. To the best of our knowledge, microsurgical reconstruction in infants at this age with congenital malignant tumors has not yet been reported. The case shows that Plastic surgery can play an important role in pediatric oncology and should routinely be integrated into the multi-modal treatment concepts. (c) 2006 Wiley-Liss, Inc.

    Posterior transversus abdominis plane blocks have been reported to be an effective method of providing analgesia after lower abdominal surgery. We compared the efficacy of a novel technique of providing continuous transversus abdominis plane analgesia with epidural analgesia in patients on an enhanced recovery programme following laparoscopic colorectal surgery. A non-inferiority comparison was used. Adult patients undergoing elective laparoscopic colorectal surgery were randomly assigned to receive continuous transversus abdominis plane analgesia (n = 35) vs epidural analgesia (n = 35), in addition to a postoperative analgesic regimen comprising regular paracetamol, regular diclofenac and tramadol as required. Sixty-one patients completed the study. The transversus group received four-quadrant transversus abdominis plane blocks and bilateral posterior transversus abdominis plane catheters that were infused with levobupivacaine 0.25% for 48 h. The epidural group received an infusion of bupivacaine and fentanyl. The primary outcome measure was visual analogue scale pain score on coughing at 24 h after surgery. We found no significant difference in median (IQR [range]) visual analogue scores during coughing at 24 h between the transversus group 2.5 (1.0-3.0 [0-5.5]) and the epidural group 2.5 (1.0-5.0 [0-6.0]). The one-sided 97.5% CI was a 0.0 (∞-1.0) difference in means, establishing non-inferiority. There were no significant differences between the groups for tramadol consumption. Success rate was 28/30 (93%) in the transversus group vs 27/31 (87%) in the epidural group. Continuous transversus abdominis plane infusion was non-inferior to epidural infusion in providing analgesia after laparoscopic colorectal surgery. © 2013 The Association of Anaesthetists of Great Britain and Ireland.

    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.

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.

    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 Although transversus abdominis plane (TAP block is an effective way of providing analgesia in post-operative abdominal surgery patients; however, it can be considered as an anesthetic technique in high-risk cases for surgery. We report a case of a geriatric female with chronic obstructive pulmonary disease in the respiratory failure, hypotension, posted in an emergency with old perforation leading to peritonitis. The surgery was successfully conducted under bilateral TAP block, which was used as a sole anesthetic technique. TAP block can be considered as an anesthetic technique for abdominal surgery in moribund patients.

    Subcostal transversus abdominis plane (TAP) catheters have been reported to be an effective method of providing analgesia after upper abdominal surgery. We compared their analgesic efficacy with that of epidural analgesia after major upper abdominal surgery in a randomised controlled trial. Adult patients undergoing elective open hepatobiliary or renal surgery were randomly allocated to receive subcostal TAP catheters (n=29) or epidural analgesia (n=33), in addition to a standard postoperative analgesic regimen comprising of regular paracetamol and tramadol as required. The TAP group patients received bilateral subcostal TAP catheters and 1 mg.kg(-1) bupivacaine 0.375% bilaterally every 8 h. The epidural group patients received an infusion of bupivacaine 0.125% with fentanyl 2 μg.ml(-1) . The primary outcome measure was visual analogue pain scores during coughing at 8, 24, 48 and 72 h after surgery. We found no significant differences in median (IQR [range]) visual analogue scores during coughing at 8 h between the TAP group (4.0 (2.3-6.0 [0-7.5])) and epidural group (4.0 (2.5-5.3) [0-8.5])) and at 72 h (2.0 (0.8-4.0 [0-5]) and 2.5 (1.0-5.0 [0-6]), respectively). Tramadol consumption was significantly greater in the TAP group (p=0.002). Subcostal TAP catheter boluses may be an effective alternative to epidural infusions for providing postoperative analgesia after upper abdominal surgery. © 2011 The Authors.

    Full Text Available Background: Transversus abdominis plane (TAP block is suitable for lower abdominal surgeries. Blind TAP block has many complications and uncertainty of its effects. Use of ultrasonography increases the safety and efficacy. This study was conducted to evaluate the analgesic efficacy of ultrasound (USG-guided TAP block for retroperitoneoscopic donor nephrectomy (RDN. Methods: In a prospective randomized double-blind study, 60 patients undergoing laparoscopic donor nephrectomy were randomly divided into two groups by closed envelope method. At the end of surgery, USG-guided TAP block was given to the patients of both the groups. Study group (group S received inj. Bupivacaine (0.375%, whereas control group (group C received normal saline. Inj. Tramadol (1 mg/kg was given as rescue analgesic at visual analog scale (VAS more than 3 in any group at rest or on movement. The analgesic efficacy was judged by VAS both at rest and on movement, time to first dose of rescue analgesic, cumulative dose of tramadol, sedation score, and nausea score, which were also noted at 30 min, 2, 4, 6, 12, 18, and 24 h postoperatively. Total tramadol consumption at 24 h was also assessed. Results: Patients in group S had significantly lower VAS score, longer time to first dose of rescue analgesic (547.13±266.96 min vs. 49.17±24.95 min and lower tramadol consumption (103.8±32.18 mg vs. 235.8±47.5 mg in 24 h. Conclusion: The USG-guided TAP block is easy to perform and effective as a postoperative analgesic regimen in RDN, with opioids-sparing effect and without any complications.

    Effective postoperative analgesia is a key element in reducing postoperative morbidity, accelerating recovery and avoiding chronic postoperative pain. The aim of this study was to evaluate the effectiveness of ultrasound-guided Transversus Abdominis Plane (TAP) block, performed before surgical incision, in providing postoperative analgesia for patients undergoing open ventral hernia repair under general anaesthesia. Seventy elective patients scheduled for open ventral hernia repair surgery under general anaesthesia were divided randomly into two equal groups: Group I received bilateral TAP block performed before surgical incision (n = 35); Group II received systemic postoperative analgesia with parenteral opioid (morphine) alone (n = 35). Postoperatively pain scores at rest and with movement, total morphine consumption and opioid related side effects were recorded. Postoperative pain scores at rest and mobilization/cough were significantly higher in patients without TAP block (p consumption was comparable between the two groups: 0.75 ± 0.31 mg in group I (TAP) and 0.86 ± 0.29 mg in group II (MO), p = 0.1299. Patients undergoing preincisional TAP block had reduced morphine requirements during the first 24 hours after surgery, compared to patients from group II, without TAP block (p = 0.0001). There was no difference in the incidence of opioid related side effects (nausea, vomiting) in the both groups during the first 24 postoperative hours. The use of preincisional ultrasound guided TAP block reduced the pain scores at rest and with movement/cough, opioid consumption and opioid-related side effects after ventral hernia repair when compared with opioid-only analgesia.

    To assess the analgesic efficacy of transversus abdominis plane (TAP) block in patients undergoing colorectal surgery (CRS). The databases of PubMed, ISI Web of Science, and Embase were searched, and randomized controlled studies (RCTs) that compared TAP block to control for relief of postoperative pain in patients who underwent CRS were included. Outcomes, including postoperative pain at rest and with movement, morphine use, postoperative nausea and vomiting, and the length of hospital stay, were analyzed using STATA software. The weighted mean differences (WMDs) with 95% confidence intervals (95% CIs) or relative risk with 95% CI were used to present the strength of associations. A total of 7 RCTs with 511 patients were included. The results of this study suggested that TAP block significantly relieved postoperative pain during postanesthetic recovery after CRS at rest and during movement (WMDs were -0.98 [95% CI -1.57 to -0.38] and -0.68 [-1.07 to -0.30], respectively), and also decreased pain intensity during movement 24 h after CRS (WMD: -0.57 [95% CI -1.06 to -0.08]). TAP block significantly reduced opioid consumption within 24 h when compared to controls, with a WMD of 15.66 (95% CI -23.93 to -7.39). However, TAP block did not shorten the length of hospital stay. TAP block was an effective approach for relief of postoperative pain and reduced postoperative consumption of morphine. More RCTs with large sample sizes are required to confirm these findings. © 2018 The Author(s) Published by S. Karger AG, Basel.

    The study aimed to compare efficacy, safety, pain intensity and analgesic consumption in patients receiving either bilateral transversus abdominis plane (TAP) block or wound infiltration with bupivacaine after cesarean delivery (CD). A total of 216 parturient women undergoing CD under general anesthesia were randomly allocated into five groups: i) controls (group 1), ii) TAP placebo (group 2), iii) TAP (group 3), iv) wound infiltration placebo (group 4), and, v) wound infiltration (group 5). Pain intensity was assessed using a visual analogue scale (VAS). Analgesic consumptions were recorded by a blinded nurse at 6, 12, and 18 hours postoperatively. The baseline characteristics of the five groups were similar in terms of age, history of CD, and body mass indices (p>0.05). There were significant intergroup differences in VAS scores between all groups at the zero time-point (p=0.03), at the 6th hour (p=0.02), 12th hour (p=0.02), and at the 18th hour (p=0.02). Group 3 patients had lower pain scores and consumed less diclofenac than group 2 patients only within 12 hours postoperatively whereas pain intensity and analgesic consumption were not different between group 5 and group 4 patients. Group 5 patients received significantly less pethidine than group 4 and group 1 patients (p<0.001). TAP block provided better pain relief and less analgesic requirement than bupivacaine wound infiltration early after CD. Given the similar amounts of diclofenac but lower amounts of pethidine administered in the wound infiltration group, wound infiltration of bupivacaine seems promising in terms of reducing opioid use after CD under general anesthesia, especially when TAP block is not used.

    Transversus abdominis plane (TAP) block is a promising technique for analgesia after abdominal surgery. This prospective, randomized controlled trial assessed the effect of adding dexmedetomidine to bupivacaine in TAP block for donor hepatectomy. We hypothesized that this would improve postoperative morphine consumption and reduce analgesia related complication and inflammation. A total of 50 donor hepatectomy were enrolled in this study. Patients divided into two equal groups according to drugs used for TAP block. Group (B) received 20 ml of bupivacaine hydrochloride 0.25%, Group (BD) received 20 ml of bupivacaine hydrochloride 0.25% and 0.3 μg/kg dexmedetomidine, on both sides at the end of surgery and every 8 h for 48 h at right side only through inserted catheter. Primary outcome objective was morphine consumption at first 72 h. Secondary outcome objectives were morphine requirement, numbers of intake, time to first intake, pain score numerical analog scale (NAS), postoperative analgesia related complications, recovery of intestinal motility, and inflammatory markers. Data were analyzed, rescue morphine analgesia was significantly lower in (BD) group compared with (B) groups as considering total morphine consumption (B 4 ± 1.9, BD 1.5 ± 0.5, P = 0.03), numbers of morphine intake ( P = 0.04), morphine requirement ( P = 0.03), and first time of analgesia intake ( P = 0.04). NAS was significantly lower in group (BD) compared with group (B) group in the first 12 h (NAS 0 - P = 0.001, NAS 1 - P = 0.03). Adding dexmedetomidine improved gut motility, first oral intake without detectable anti-inflammatory effect. Adding dexmedetomidine to bupivacine in a surgically inserted catheter for TAP block in donor hepatectomy reduced morphine consumption without detectable anti-inflammatory effect.

    Full Text Available Purpose: Different adjuvants have been used to improve the quality and increase the duration of local anesthetics during various nerve block techniques. The current study was aimed to evaluate the effect of adding dexamethasone to bupivacaine on the quality and duration of transversus abdominis plane (TAP block. Methods: Sixty adult patients undergoing elective open abdominal hysterectomy were randomly allocated to receive TAP block using 20 mL of bupivacaine hydrochloride 0.25% + 2 mL saline 0.9% (control group, n=30 or 20 mL of bupivacaine hydrochloride 0.25% + 2 mL dexamethasone "8 mg" (dexamethasone group, n=30. The primary outcome was postoperative pain, as evaluated by visual analog scale (VAS for pain scoring at 1, 2, 4, 12, 24 and 48 h postoperatively, whereas the secondary outcomes were time to first analgesia (TFA, morphine consumption and the occurrence of nausea, vomiting or somnolence. Results: The pain VAS score was significantly lower at the postoperative 2 h (4.9 vs. 28.1, P=0.01, 4 h (12.2 vs. 31.1, P=0.01 and 12 h (15.7 vs. 25.4, P=0.02. Furthermore, TFA was significantly longer in the dexamethasone group (459.8 vs. 325.4 min, P=0.002, with lesser morphine requirements in the postoperative 48 h (4.9 vs. 21.2 mg, P=0.003 and lower incidence of nausea and vomiting (6 vs. 14, P=0.03. No complications attributed to the block were recorded. Conclusion: Addition of dexamethasone to bupivacaine in TAP block prolonged the duration of the block and decreased the incidence of nausea and vomiting.

    It is reported that following abdominal surgery, transversus abdominis plane (TAP) block can reduce postoperative pain. The primary outcome of this study was the evaluation of the efficacy of TAP block on pain intensity following cesarean delivery with Pfannenstiel incision. Fifty pregnant women were randomized blindly to receive either a TAP block with 15 ml 0.25% bupivacaine in both sides (group T, n = 25) or no blockade (group C, n = 25) at the end of the surgery, which was performed with a Pfannenstiel incision under general anesthesia. The pain intensity in the patients was assessed by a blinded investigator at the time of discharge from recovery and at 6, 12, and 24 h postoperatively, with a visual analogue scale (VAS) for pain. The women in the TAP block group had significantly lower VAS pain scores at rest and during coughing and consumed significantly less tramadol than the women in group C [50 mg (0-150) vs. 250 mg (0-400), P = 0.001]. There was a significantly longer time to the first request for analgesic in the TAP block group [210 min (0-300) vs. 30 min (10-180) in group C, P = 0.0001]. Two-sided TAP block with 0.25% bupivacaine in parturients who undergo cesarean section with a Pfannenstiel incision under general anesthesia can decrease postoperative pain and analgesic consumption. The time to the first analgesic rescue was longer in the parturients who received the TAP block.

    Full Text Available Pethidine is a synthetic opioid with local anesthetic properties. Our goal was to evaluate the analgesic efficacy of pethidine for achieving the ultrasound-guided oblique subcostal transversus abdominis plane (OSTAP block in laparoscopic cholecystectomy. This prospective, double-blind study included 79 patients of physical status I and II according to American Society of Anesthesiologists, scheduled for elective laparoscopic cholecystectomy. The patients were randomly allocated into three groups, depending on the drug used to achieve preoperative bilateral OSTAP block: 1 OSTAP-Placebo (treated with normal saline; 2 OSTAP-Bupivacaine (treated with 0.25% bupivacaine; and 3 OSTAP-Pethidine (treated with 1% pethidine. The efficacy of pethidine in achieving the OSTAP block was analyzed using visual analog scale (VAS, intraoperative opioid dose, opioid consumption in post anesthesia care unit, and opioid consumption in the first 24 postoperative hours. The pain scores assessed by VAS at 0, 2, 4, 6, 12, and 24 hours were significantly lower in OSTAP-Pethidine than in OSTAP-Placebo group (p < 0.001. The mean intraoperative opioid consumption was significantly lower in OSTAP-Pethidine compared to OSTAP-Placebo group (150 versus 400 mg, p < 0.001, as well as the mean opioid consumption in the first 24 hours (20.4 versus 78 mg, p < 0.001. Comparing VAS assessment between OSTAP-Bupivacaine and OSTAP-Pethidine groups, statistically significant differences were observed only for the immediate postoperative pain assessment (0 hours, where lower values were observed in OSTAP-Pethidine group (p = 0.004. There were no statistically significant differences in the incidence of postoperative nausea and vomiting (p = 0.131 between the groups. The use of 1% pethidine can be an alternative to 0.25% bupivacaine in achieving OSTAP block for laparoscopic cholecystectomy.

    Full Text Available Background. Caesarean delivery can be associated with considerable postoperative pain. While the benefits of transversus abdominis plane (TAP and ilioinguinal-iliohypogastric (II-IH nerve blocks on pain after caesarean delivery via Pfannenstiel incision have been demonstrated, no enough investigations on the comparison of these blocks on pain after caesarean delivery have been conducted in our setup. Method. An institutional-based prospective observational cohort study was conducted to compare the analgesic efficacy of those blocks. We observed 102 postoperative parturients. The outcome measure was the severity of pain measured using a numeric rating scale. Result. Twenty-four hours after surgery, the NRS score at rest was (0.90 ± 0.80 versus (0.67 ± 0.58 and at movement (1.2 ± 1.07 versus (0.88 ± 0.76 for the TAP and II-IH groups, respectively. Twenty-four hours after surgery, the mean tramadol consumption was (55.45 ± 30.51 versus (37.27 ± 27.09 mg in TAP and II-IH groups, respectively (p = 0.009. The mean first analgesic requirement time was also prolonged in the II-IH group. Conclusion and Recommendations. There was no statically significant difference between TAP and II-IH blocks regarding postoperative pain score, but the II-IH block significantly reduced the total tramadol consumption and prolonged the time to first analgesic request than TAP. Thus, we recommend the II-IH nerve block.

    Transversus abdominis plane (TAP) block used for management of surgical abdominal pain by injecting local anesthetics into the plane between the internal oblique and transversus abdominis muscles. We aimed to explore the effect of adding morphine to bupivacaine in ultrasound guided TAP-block in patients undergoing lower abdominal cancer surgery. Randomized, double-blind, prospective study. Clinical trial identifier: NCT02566096. Academic medical center. Sixty patients were enrolled in this study after ethical committee approval. Patients divided into 2 groups (30 each): Bupivacaine group (GB): given ultrasound guided TAP-block 20ml 0.5% bupivacaine diluted in 20ml saline; Morphine group (GM): given ultrasound guided TAP-block with 20ml 0.5% bupivacaine+10mg morphine sulphate diluted in 20ml saline. Patients were observed for total morphine consumption, time for first request of rescue analgesia, sedation scores, hemodynamics and side effects for 24h postoperatively. Morphine added to bupivacaine in TAP block compared to bupivacaine alone reduced total morphine consumption (5.33±1.28mg) (10.70±3.09mg) respectively (p0.05). Addition of morphine to bupivacaine in TAP block is effective method for pain management in patients undergoing major abdominal cancer surgery without serious side effects.

    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.

    The aim of this study was to evaluate the dose effect and the resulting binocular single vision for inferior oblique muscle recession in patients with Grave's orbitopathy. The evaluation covered all patients (n = 13) between 2010-2013 treated with recession of the inferior oblique muscle for vertical deviation caused by inferior fibrosis of the contralateral eye. The inclusion criterion was a small vertical squint angle with excyclotorsion. The corrected vertical squint angle was 3.75° [7 pdpt] (median, min 1.5° [3 pdpt], max 8° [16 pdpt]) in primary position and 5.5° in adduction [11pdpt] (median, min 3°[6 pdpt], max 9°[18pdpt]). Excyclotorsion was 4° [8 pdpt] (median, min 1° [2 pdpt], max 9° [18 pdpt]). Elevation was only slightly impaired and the side difference was 5° (median). The recession distance was preoperatively determined: 0.5° squint angle reduction per mm recession distance (calculation from patients who received surgery before 2010). Inferior oblique recession generated a good field of binocular single vision (BSV) for all patients. All patients reached BSV in the central area (20°) and within 30° of downgaze. Sixty nine percent of the patients were completely diplopia free in downgaze. Diplopia persisted in more than half of the patients in up gaze outside 15°. Squint reduction was 0.5° [1 pdpt] [0.45-0.67]/per mm recession distance in primary position and 0.65° [1.3 pdpt] [0.55-0.76]/per mm for the vertical deviation in adduction. Excyclotorsion was reduced to ≤ 2° in 77 % of the patients. Inferior oblique muscle recession can be very successfully performed on the contralateral eye in patients with mild inferior rectus muscle fibrosis. Surgery at the contralateral yoke muscle prevents the risk of overeffect with resulting diplopia in downgaze, which could occur if small distance recession had been performed at the inferior rectus muscle. An overeffect in relation to inferior oblique recession will only

    Full Text Available Acupuncture has been increasingly used in the treatment of muscle damage associated with sports activities. However, studies on the immediate effects of one-time acupuncture on the muscles of athletes are clearly lacking. Thus, this study aimed to examine the effects of acupuncture therapy on the maximal voluntary isometric contraction (MVIC electromyography (EMG of the rectus femoris and tibialis anterior muscles. This study was conducted among 20 healthy male college students who had no musculoskeletal disease. The participants were subjected to 3 different experimental conditions and subsequently grouped based on these conditions: real acupuncture, sham acupuncture, and control. A 7-day washout period was implemented to avoid any transient effects on the physiological and psychological conditions of the participants. Subsequently, an electromyogram patch was attached on the most developed area in the middle of the origin and insertion of the rectus femoris and tibialis anterior muscles. The percent MVIC, which was used to standardize the signal from the electromyogram, was determined, and the maximal value from the MVIC of the rectus femoris and tibialis anterior muscles was measured. The MVIC EMG activities of both femoris (F = 6.633, p = 0.003 and tibialis anterior (F = 5.216, p = 0.008 muscles were significantly different among all groups. Accordingly, the results of a posthoc test showed that the real acupuncture group had higher MVIC EMG activities in the femoris (p = 0.002 and tibialis anterior (p = 0.006 muscles compared with the control group. These results suggest that treatment with real acupuncture resulted in significantly higher MVIC EMG activities of the rectus femoris and tibialis anterior muscles than the other treatments. Hence, acupuncture may be helpful in the improvement of muscle strength among athletes in the physical fitness field.

    According to the literature, accommodative esotropia has an unpredictable course when nonsurgical treatment is considered, especially in cases with a high accommodative convergence/accommodation ratio (AC/A). The aim of this study was to compare the results of augmented recession, slanted recession, and recession with posterior fixation suture of the medial rectus muscles in the treatment of high AC/A esotropia. Twenty-eight children (4 to 14 years old) with high AC/A esotropia with a near-distance disparity greater than 10 PD were included in a prospective, randomized, blinded clinical trial. Nine children underwent recession of both medial rectus muscles and posterior fixation suture (Faden procedure), 9 children underwent augmented recession of the medial rectus muscles, and 10 children underwent slanted recession of both medial rectus muscles. The amount of esodeviation was measured before strabismus surgery and at least 6 months postoperatively. In the augmented recession group, the mean near-distance disparity was reduced from 16.33 +/- 2.17 PD preoperatively to 7.55 +/- 3.87 PD postoperatively (54.21%; P = .056). In the Faden procedure group, it was reduced from 15.22 +/- 4.08 PD to 2.55 +/- 4.03 PD (80.7%; P = .056). In the slanted recession group, it was reduced from 15.50 +/- 4.30 PD to 4.10 +/- 4.80 PD (67.55%; P = .056). The Faden procedure had the best outcome, but slanted recession also was successful. Because of our good results and an easy, non-invasive approach without any additional complications, we recommend slanted recession to treat high AC/A esotropia.

    Pain control after a laparoscopic cholecystectomy can represent a challenge, considering the side effects due to standard analgesia methods. Recently the transversus abdominis plane block (TAP Block) has been used as a part of multimodal analgesia with promising results. The subcostal approach (OSTAP Block), a variant on the TAP block, produces reliable unilateral supraumbilical analgesia. This study evaluated the efficacy of the OSTAP block with bupivacaine in laparoscopic cholecystectomy compared with the placebo OSTAP block. Sixty ASA I/II adult patients listed for elective laparoscopic cholecystectomy were randomly allocated in one of two groups: Group A (OSTAP placebo) received preoperatively bilateral OSTAP block with sterile normal saline and Group B (OSTAP bupivacaine) received bilateral preoperatively OSTAP block with the same volumes of 0.25% bupivacaine. Twenty-four hours postoperative opioid consumption, the dose of opioid required during surgery, opioid dose in the recovery unit (PACU) and PACU length of stay were evaluated. The quality of analgesia was assessed by the Visual Analogue Scale (VAS) at specific interval hours during 24 h, at rest and with movement. The mean intraoperative opioid consumption showed a significant difference between the two groups, (385 ± 72.52 mg in group A vs 173.67 ± 48.60 mg in group B, p consumption showed a statistically significant difference between groups (32 ± 26.05 mg vs 79 ± 16.68 mg, p < 0.001). PACU length of stay was significantly lower for group B patients compared with group A patients (20.67 ± 11.27 min vs 41.67 ± 12.41 min, p < 0.001). The OSTAP bupivacaine group had a statistically significant lower pain score than the OSTAP placebo group at 0, 2, 4, 6, 12, 24 h, both at rest and with movement. No signs or symptoms of local anaesthetic systemic toxicity or other complications were detected. OSTAP block with bupivacaine 0.25% can provide effective analgesia up to 24 hours after laparoscopic

    Epidural analgesia is considered the standard of care but cannot be provided to all patients Liposomal bupivacaine has been approved for field blocks such as transversus abdominis plane (TAP) blocks but has not been clinically compared against other modalities. In this retrospective propensity matched cohort study we thus tested the primary hypothesis that TAP infiltration are noninferior (not worse) to continuous epidural analgesia and superior (better) to intravenous opioid analgesia in patients recovering from major lower abdominal surgery. 318 patients were propensity matched on 18 potential factors among three groups (106 per group): 1) TAP infiltration with bupivacaine liposome; 2) continuous Epidural analgesia with plain bupivacaine; and; 3) intravenous patient-controlled analgesia (IV PCA). We claimed TAP noninferior (not worse) over Epidural if TAP was noninferior (not worse) on total morphine-equivalent opioid and time-weighted average pain score (10-point scale) within first 72 hours after surgery with noninferiority deltas of 1 (10-point scale) for pain and an increase less of 20% in the mean morphine equivalent opioid consumption. We claimed TAP or Epidural groups superior (better) over IV PCA if TAP or Epidural was superior on opioid consumption and at least noninferior on pain outcome. Multivariable linear regressions within the propensity-matched cohorts were used to model total morphine-equivalent opioid dose and time-weighted average pain score within first 72 hours after surgery; joint hypothesis framework was used for formal testing. TAP infiltration were noninferior to Epidural on both primary outcomes (pconsumption (p = 0.37). We did not find noninferiority of Epidural over IV PCA on pain scores (P = 0.13) and nor did we find superiority on opioid consumption (P = 0.98). TAP infiltration with liposomal bupivacaine and continuous epidural analgesia were similar in terms of pain and opioid consumption, and not worse in pain compared with IV PCA

    To determine the preoperative variables affecting early and late favorable outcomes of bilateral lateral rectus recession surgery for concomitant exotropia. A retrospective study of 65 patients with concomitant exotropia (constant and intermittent) who had bilateral lateral rectus recession was conducted. The follow-up period was more than 1 year in all patients. Preoperative parameters were obtained and evaluated using univariate analysis. Sixty-five patients with concomitant exotropia who underwent bilateral lateral rectus recession were included. In the early and late postoperative outcome, 78% and 82% of the patients were in the success group, respectively. Meanwhile, 22% and 18% were in the failure group, respectively. There was no association between postoperative outcome and preoperative variables i.e. age at onset (p = 0.841, 0.591), age at surgery (p = 0.564, 0.634), interval between onset and surgery (p = 0.506, 0.753), preoperative deviation (p = 0.278, 0.211), refractive error (p = 0.217, 0.136), anisometropia (p = 0.946, 0.946), phase of exotropia (p = 0.741, 0.013), A-V pattern (p = 1.000, 1.000), stereopsis (p = 0.841, 0.268) and amblyopia (p = 0.569, 0.567). Preoperative variables could not be used to predict the early and late postoperative outcome.

    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.

    After the introduction of mesh in inguinal hernia repair, the focus to improve surgical technique has changed from recurrence to chronic postoperative inguinal pain. At present, the most common surgical techniques are the Lichtenstein hernioplasty and total extraperitoneal procedure. Both techniques have their own specific disadvantages, with regard to potential nerve damage and the necessity of general anesthesia, respectively. The goal of this study was to evaluate the results of a new technique in which the inguinal nerves are not at risk, and in which general anesthesia is not needed: trans rectus sheath extraperitoneal procedure (TREPP). Between 2006 and 2010, a total of 1,000 patients were treated for inguinal hernia with TREPP. A questionnaire concerning pain, sensibility changes, patient satisfaction, and recurrence was sent to all patients. The questionnaire was completed by 932 patients. Almost 90% of patients had not experienced any pain since the surgical procedure; 8% of patients reported experiencing some pain, but less than preoperatively; and 2% of patients reported an increase in pain postoperatively. Recurrence occurred in 1 and 3% were unsure about this. Reduced sensibility of the scar, scrotum, and upper leg was reported by 12.4, 1.4, and 1.5%, respectively. Overall, 97.4% of patients were satisfied with the results of the surgical procedure. The time period in which TREPP was performed was not associated with any of the outcome measures. TREPP has proven to be a feasible new technique for inguinal hernia repair, with excellent results, justifying a randomized controlled trial in which TREPP should be compared with standard techniques.

    Full Text Available 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.

    Pilates method has been recommended for patients with chronic low back pain (CLBP) and the activation of transversus abdominis has been deemed to play an important role in the improvement of these patients. Nevertheless, the evidence of the activation of TrA in Pilates practitioners remains unclear. To assess the effectiveness of 12 weeks of Pilates practice in disability, pain, kinesiophobia and transversus abdominis activation in patients with chronic nonspecific Low Back Pain. A randomized controlled trial was carried out. A single-blind randomized controlled trial with repeated measures at 6 and 12 weeks was carried out. A total of ninety eight patients with low back pain were included and randomly allocated to a Pilates Mat group (PMG) equipment based with apparatus Pilates (PAG) or control group (CG). Roland Morris Disability Questionnaire (RMDQ), visual analog scale (VAS) Tampa Scale of Kinesiophobia (TSK), and transversus abdominis (TrA) activation assessed by real time ultrasound measurement (US) were assessed as outcome measures. Improvement were observed in both intervention groups in all the included variables at 6 and 12 weeks (ppain, function and kinesiophobia. Significant differences were observed after 12 weeks of intervention in PMG and PAG with faster improvement in PAG suggesting that, feedback provided by equipment could help in the interiorization of Pilates principles.

    Full Text Available BACKGROUND The transversus abdominis plane (TAP block is a technique which blocks the sensory nerves supplying the anterior abdominal wall. This prospective cohort study was done to evaluate the effectiveness of TAP block for postoperative pain in patients undergoing total abdominal hysterectomy. MATERIALS AND METHODS Sixty patients of ASA Grade 1 and 2 undergoing open abdominal hysterectomy were prospectively allocated into Group A and Group B. Group A patients (n = 30, received ultrasound guided TAP block along with 1 gm paracetamol 8th hourly and tramadol 1 mg/ kg as rescue analgesic. Group B patients (n = 30 received standard analgesic care with 1 gm paracetamol 8th hourly and tramadol 1 mg/ kg as rescue analgesic. TAP block was performed on completion of surgery in Group A patients by instilling 20 ml of 0.25% levobupivacaine into the transversus abdominis plane on each side under ultrasound guidance. Postoperatively Verbal Numerical Rating Scale, Sedation score, Nausea categorical scoring scale at 2, 4, 6, 12 and 24 hours and total tramadol requirement in first 24 hours were assessed in each group. RESULTS Verbal Numerical Rating Scale score was significantly reduced in Group A compared to Group B at 2, 4, 6 and 24 hours postoperatively and there was no difference in scores 12 hours postoperatively. Nausea was significantly lower in Group A patients at 2, 4 and 6 hours postoperatively with no difference at 12 and 24 hours postoperatively. There was significant difference in the sedation scale at 4, 6 and 24 hours postoperatively and no difference between both groups at 2 hours and 12 hours postoperatively. Total tramadol requirement in first 24 hours postoperatively was significantly lower in Group A compared to Group B (60.83 ± 14.208 mg Vs. 121.67 ± 19.402 mg, P value< 0.00. CONCLUSION Ultrasound guided TAP block along with standard analgesic care provided better analgesia as compared to standard analgesic care alone in the first 24

    Full Text Available Objective. To assess different doses of nalbuphine with flurbiprofen compared to sufentanil with flurbiprofen in multimodal analgesia efficacy for elderly patients undergoing gastrointestinal surgery with a transverse abdominis plane block (TAPB. Methods. 158 elderly patients scheduling for elective open gastrointestinal surgery under general anesthesia and TAPB were randomly assigned to four groups according to different doses of nalbuphine with flurbiprofen in postoperative intravenous analgesia (PCIA. Postoperative pain intensity, effective pressing numbers of PCIA, and adverse effects were recorded at 6, 12, 24, and 48 hours after surgery. Results. Postoperative pain intensity, effective pressing numbers, and the incidence of postoperative nausea and vomiting (PONV were similar among the four groups after surgery, while the severity of PONV was decreased in Group L compared with Group S at 6, 12, and 48 h after surgery. No individual experienced pruritus, respiratory depression, or hypotension. Conclusions. Low dose of nalbuphine (15 μg·kg−1·ml−1 combined with flurbiprofen is superior for elderly patients undergoing elective open gastrointestinal surgery with TAPB in terms of the efficient postoperative analgesia and decreased severity of PONV. This trial is registered with NCT02984865.

    Patients undergoing renal transplant (RT) have altered drug/opioid pharmacokinetics. Transversus abdominis plane (TAP) block in renal transplant recipients has been recently evaluated for analgesic and opioid-sparing potential by many trials. The studies comparing TAP-block to conventional analgesic regimens for RT were searched. Comparisons were made for total opioids consumed (as morphine-equivalents) during the first postoperative 24-h (primary objective), intraoperative, and immediate-postoperative period. Pain scores and postoperative nausea-vomiting (PONV) were also evaluated. Trial sequential analysis (TSA) was used to quantify the strength of analysis. Ten-trials with 258 and 237 patients in control and TAP-block group, respectively, were included. TAP-block decreased the 24-h (reported in 9-trials) opioid consumption by 14.61 ± 4.34 mg (reduction by 42.7%, random-effects, P consumption also decreased by 2.06 ± 0.63 mg (reduction of 27.8%) (random effects, P consumption in RT recipients. Persistent and better pain control is achieved when TAP-Block is used. Benefits of TAP block extend beyond the analgesic actions alone as it also decreases the 24-h incidence of postoperative nausea vomiting as well. The technique of the block needs standardization for RT recipients.

    Women undergoing cesarean (CS) delivery present a unique set of challenges to the anesthetist in terms of postoperative pain management. This study was conducted to compare the analgesic efficacy of intrathecal buprenorphine (ITB) with ultrasound-guided transversus abdominis plane (TAP) block in post-CS delivery pain. A prospective randomized comparative study of sixty American Society of Anesthesiologists physical status I and II pregnant patients divided into two groups of thirty each as ITB group and TAP block group after satisfying the inclusion criteria. In the present study, demographic data were comparable between both groups. The time to first analgesic request was significantly longer in ITB group (389.67 ± 90.78 min) compared to TAP group (669.17 ± 140.65 min) and was statistically significant, P consumption in the first 24 h was higher in the TAP group (3.5 g) compared to the ITB group (1.13 g) and was statistically significant, P consumption during the first 24 h. The benefits of neuraxial opiates are significant and far outweigh the side effects.

    Objective To evaluate the effects of an ultrasound-guided transverse abdominis plane (US-TAP) block used for postoperative pain relief by comparing the efficacy of two different volumes/concentrations of the local anaesthetic bupivacaine in patients undergoing laparoscopic cholecystectomies. Methods This randomized study enrolled patients undergoing laparoscopic cholecystectomies. They were randomized to two groups: group A received a 20 ml US-TAP block (50 mg bupivacaine +10 ml saline solution) and group B received a 30 ml US-TAP block (50 mg bupivacaine + 20 ml saline solution). The intraoperative consumption of remifentanil, the requirement for postoperative rescue analgesics, patient satisfaction scores, postoperative complications, and postoperative pain as measured by a visual analogue scale at 20 min, 12 h, and 24 h were recorded. Results A total of 60 patients enrolled in the study. There were no differences between the two groups with respect to demographic characteristics, duration of anaesthesia and patient satisfaction scores. The intraoperative consumption of remifentanil, postoperative VAS scores (20 min, 12 h and 24 h) and the requirement for postoperative analgesics were all significantly lower in group B who received a larger volume but a lower concentration of local anaesthetic solution compared with group A. Conclusion A US-TAP block can form part of a balanced postoperative analgesic regimen following laparoscopic cholecystectomy.

    While opioids are the mainstay for post-operative analgesia after lower segment caesarean section, they are associated with various untoward effects. Ultrasound guided transversus abdominis plane (TAP) block has been postulated to provide effective analgesia for caesarean section. We evaluated the analgesic efficacy of this block for post caesarean analgesia in a randomised controlled trial. One hundred thirty-nine mothers undergoing caesarean delivery were randomised to receive TAP block with either 20 ml 0.375% ropivacaine or 20 ml saline after obtaining informed consent. All the subjects received a standard spinal anaesthetic and diclofenac was administered for post-operative pain. Breakthrough pain was treated with tramadol. Post-operatively, all the subjects were assessed at 0, 2, 4, 6, 8, 10, 12, 18 & 24 h. The primary outcome was the time to first analgesic request. The secondary measures of outcome were pain, nausea, sedation, number of doses of tramadol administered and satisfaction with the pain management. The median (interquartile range) time to first analgesic request was prolonged in the TAP group compared to the control group (p consumption when used for multimodal analgesia for pain relief after caesarean section. However, the risk of local anaesthetic systemic toxicity remains unknown with this block. Hence larger safety trials and measures to limit this complication need to be ascertained. The trial was registered with the Clinical Trial Registry of India ( CTRI/2017/03/008194 ) on 23/03/2017 (trial registered retrospectively).

    [Purpose] The aim of this study was to investigate muscle thickness changes in the external oblique (EO), internal oblique (IO), and transversus abdominis (TrA) muscles between the neutral position and trunk rotation, under a state of rest without voluntary contractions, and isometric contractions to both sides with resistance of 50% of the maximum trunk rotation strength. [Subjects] The subjects of this study were 21 healthy young men. [Methods] Muscle thickness changes in the EO, IO, and TrA in each position and state were evaluated by ultrasound. The range of motion at maximum trunk rotation and the maximum strength of trunk rotation were measured using a hand-held dynamometer. [Results] In the neutral position and at 50% trunk rotation to the right side, the thicknesses of the IO and TrA significantly increased with resistance. In both states, the thicknesses of the IO and TrA significantly increased at 50% trunk rotation to the right side. [Conclusion] The muscular contractions of the IO and TrA were stronger during ipsilateral rotation than in the neutral position and with resistance than at rest. Moreover, the muscular contraction was strongest in the resistive state during ipsilateral rotation.

    Background The goal of this study was to evaluate patient satisfaction with four common types of breast reconstruction performed at our institution: latissimus dorsi myocutaneous (LDM) flap reconstruction with or without implants, pedicled transverse rectus abdominis musculocutaneous (TRAM) flap reconstruction, and free deep inferior epigastric perforator (DIEP) flap reconstruction. Methods A custom survey consisting of questions that assessed general and aesthetic satisfaction was sent to patients who had undergone breast reconstruction in the last 5 years. The clinical data and details of the surgery were also collected from the patients who returned the surveys. We compared satisfaction rates across the four breast reconstruction types and analyzed the effects of various factors on overall general and aesthetic satisfaction rates using a binary logistic regression model. Result A total of 207 (72%) patients completed the questionnaires. Overall, significant differences in general and aesthetic satisfaction among the four procedures were not observed. A multivariate analysis revealed that the factor “complications” (p = 0.001) played a significant role in general satisfaction and that the factors “> 2 years since reconstruction” (p = 0.043) and “age > 35 years” (p = 0.05) played significant roles in overall aesthetic satisfaction. Conclusion The present study demonstrated that the type of breast reconstruction might not influence satisfaction in Chinese patients. PMID:26562294

    Transverse rectus abdominis musculocutaneous (TRAM) flap is the most common procedure performed for breast reconstruction after mastectomy for breast cancer. Obesity is a relative contraindication, and complex modifications have been proposed in the pedicled technique for obese patients. We studied ischemic complications in our patients to investigate the effect of body weight on the outcome of TRAM flap breast reconstruction. Pertinent data from medical records of patients receiving a TRAM flap surgery from 1986 to 2011 were extracted. Patients were divided into three groups based on the body mass index (BMI): normal (obese (>30 kg/m(2)). Flap necrosis is defined as any visible nonviable tissue in the reconstructed breast. It was observed that 117 patients had received TRAM flap reconstruction. Fifty-eight patients were excluded. Of the remaining 59 cases, 24 had normal BMI, 21 were overweight, and 14 were obese. No patient was found to develop flap necrosis. Outcome of TRAM flap breast reconstruction in obese patients is similar to nonobese patients. No major necrosis in need of reoperation was identified in the studied obese patients. It was concluded that categorizing obesity as a relative contraindication to TRAM flap breast reconstruction should be revisited based on larger cohort studies.

    Contralateral prophylactic mastectomy (CPM) is being performed with increased frequency. Predictors of CPM and their impact on breast reconstruction are examined. A retrospective review of a dually trained oncologic and plastic surgeon's experience with patients undergoing total mastectomy from 2002 to 2012 was performed. Patients who underwent bilateral therapeutic mastectomies or who had previous contralateral mastectomy were excluded from this series. Four hundred forty-six patients were treated with total mastectomy and 174 (39%) underwent CPM. The incidence of CPM nearly tripled over the period studied. Compared to women treated with unilateral mastectomy, women who elected for CPM were younger (mean age, 50.4 vs 56.8 years, P mastectomy. Incidental contralateral cancers were discovered in 4% of women who underwent CPM (n = 7), lobular carcinoma in situ in 2.3% (n = 4), and atypical lesions in an additional 11.6% (n = 20). Women who underwent CPM favored reconstruction with breast implants (60.9% vs 17.3%), whereas the transverse rectus abdominis musculocutaneous flap predominated among their unilateral counterparts (38.6% vs 15.5%). Among women who underwent immediate breast reconstruction, the addition of a contralateral procedure expectedly increased breast complication rates (50.3% vs 35.0%, P = 0.007), especially the more severe complications that required hospitalization or reoperation (18.6% vs 5.0%, P procedure is significant.

    [Purpose] The purpose of this study was to examine correlations between measurement time and different expansibility of the elastic tape on the rectus femoris and body sway index with plyometric exercise. [Subjects and Methods] The subjects of this study were 24 healthy men. C90 area, C90 angle, trace length, sway average velocity for body sway index were measured using a force plate by BT4. The collected data were analyzed using Kendall's coefficient of concordance. [Results] All of body sway index on measuring follow up 24 hours after removing tape were significantly decreased than before and right after plyometric exercise. No significant correlations were found between body sway index and different expansibility of the elastic tape. [Conclusion] It appears that different expansibility of the elastic tape does not affect the ability to body sway index. Carry over effect of taping was verified on measuring follow up 24 hours after removing tape through the decreasing body sway index.

    To investigate whether cross-sectional area (CSA) of the suboccipital muscles was associated with active trigger points (TrPs) in chronic tension-type headache (CTTH). Magnetic resonance imaging (MRI) of the cervical spine was performed in 11 females with CTTH aged from 26 to 50 yrs old. CSA for both rectus capitis posterior minor (RCPmin) and rectus capitis posterior major (RCPmaj) muscles were measured from axial T1-weighted images, using axial MRI slices aligned parallel to the C2/3 intervertebral disc. A headache diary was kept for 4 wks to record the pain history. TrPs in the suboccipital muscle were identified by eliciting referred pain to palpation, and increased referred pain with muscle contraction. TrPs were considered active if the elicited referred pain reproduced the head pain pattern and features of the pattern seen during spontaneous headache attacks. Active TrPs were found in six patients (55%), whereas the remaining five patients showed latent TrPs. CSA of the RCPmin was significantly smaller (F = 13.843; P = 0.002) in the patients with active TrPs (right side: 55.9 +/- 4.4 mm; left side: 61.1 +/-: 3.8 mm) than in patients with latent TrPs (right side: 96.9 +/- 14.4 mm; left side: 88.7 +/- 9.7 mm). No significant differences were found for CSA of the RCPmaj between the patients with either active or latent TrP (P > 0.5). It seems that muscle atrophy in the RCPmin, but not in the RCPmaj, was associated with suboccipital active TrPs in CTTH, although studies with larger sample sizes are now required. It may be that nociceptive inputs in active TrPs could lead to muscle atrophy of the involved muscles. Muscle disuse or avoidance behavior can also be involved in atrophy.

    Full Text Available Manar A Ghali Ophthalmology Department, Faculty of Medicine, Zagazig University, Zagazig, Egypt Purpose: To compare and evaluate the efficacy of two different surgical techniques for the treatment of near-distance disparity esotropia; combined resection–recession and recession–retroequatorial myopexy of medial rectus muscles. Patients and methods: This prospective study included 28 patients diagnosed with convergence excess esotropia who had worn their full cycloplegic refraction and/or bifocal glasses for at least 6 months and still had near-distance disparity esotropia. The patients were divided into 2 groups; Group I underwent combined bimedial rectus muscles resection 2.5 mm from the insertion end with recession based on near-angle esotropia according to current surgical tables with 1 mm add of recession for each muscle, while Group II underwent bimedial recession based on far angle combined with retroequatorial myopexy at 13–14 mm from insertion. A satisfactory result was defined as orthophoria or esotropia <10 prism diopters (∆ at near and distance with reduction of the near-distance disparity to <10 ∆. The patients were followed up for at least 2 years for stability of correction and late onset consecutive exotropia. Results: In Group I, all the patients had satisfactory alignments at near and far with residual near–far disparity ≤10 ∆, no cases of overcorrection at far was reported; while in Group II, all cases had orthophoria at far, but 4 cases (28.6% showed near–far disparity >10 ∆. Conclusion: The technique of combined resection–recession is safe, easy and more effective in the treatment of near-distance disparity esotropia regardless of the level of accommodative convergence/accommodation ratio, with stability of results though longer follow-up period is still needed.

    Anesthesiologists play an important role in postoperative pain management. For analgesia after lower abdominal surgery, epidural analgesia and ultrasound-guided transversus abdominis plane (TAP) block are suitable options. The study aims to compare the analgesic efficacy of both techniques. Seventy-two patients undergoing lower abdominal surgery under spinal anesthesia were randomized to postoperatively receive lumbar epidural catheter (Group E) or ultrasound-guided TAP block (Group T) through intravenous cannulas placed bilaterally. Group E received 10 ml 0.125% bupivacaine stat and 10 ml 8 th hourly for 48 h. Group T received 20 ml 0.125% bupivacaine bilaterally stat and 20 ml bilaterally 8 th hourly for 48 h. Pain at rest and on coughing, total paracetamol and tramadol consumption were recorded. Analgesia at rest was comparable between the groups in the first 16 h. At 24 and 48 h, Group E had significantly better analgesia at rest ( P = 0.001 and 0.004 respectively). Patients in Group E had significantly higher number of patients with nil or mild pain on coughing at all times. Paracetamol consumption was comparable in both groups, but tramadol consumption was significantly higher in Group T at the end of 48 h ( P = 0.001). For lower abdominal surgeries, analgesia provided by intermittent boluses of 0.125% is comparable for first 16 h between epidural and TAP catheters. However, the quality of analgesia provided by the epidural catheter is superior to that provided by TAP catheters beyond that both at rest and on coughing with reduced opioid consumption.

    The optimal local-anaesthetic (LA) dose for transversus-abdominis-plane (TAP) block is unclear. In this meta-analysis, we aimed to determine whether TAP blocks for Caesarean delivery (CD) with low-dose (LD) LA demonstrated non-inferiority in terms of analgesic efficacy, compared with high-dose (HD) LA. A literature search was performed for randomised controlled trials examining the analgesic efficacy of TAP blocks vs control after CD. The different dosing used in these studies was classified as HD or LD (bupivacaine equivalents >50 or ≤50 mg per block side, respectively). The pooled results of each dose group vs control were indirectly compared using the Q test. The primary outcome was 24 h opioid consumption. Secondary outcomes included 6 and 24 h postoperative pain scores, time to first analgesia, 6 h opioid consumption, opioid-related side-effects, and maternal satisfaction. Fourteen studies consisting of 770 women (389 TAP and 381 control) were included. Compared with controls, the 24 h opioid consumption (milligram morphine equivalents) was lower in HD [mean difference (MD) 95% confidence interval (CI) -22.41 (-38.56, -6.26); P=0.007; I 2 =93%] and LD [MD 95% CI -16.29 (-29.74, -2.84); P=0.02; I 2 =98%] TAP groups. However, no differences were demonstrated between the HD and LD groups (P=0.57). There were also no differences between the HD and LD groups for the 6 h opioid consumption, time to first analgesia, 6 and 24 h pain scores, postoperative nausea and vomiting, pruritus, and maternal satisfaction. Low-dose TAP blocks for Caesarean delivery provide analgesia and opioid-sparing effects comparable with the high-dose blocks. This suggests that lower doses can be used to reduce local anaesthetic toxicity risk without compromising the analgesic efficacy. Copyright © 2017 British Journal of Anaesthesia.

    Full Text Available Background and Aims: Transversus abdominis plane (TAP block is a popular technique for post-operative analgesia in abdominal surgeries. The aim of the study was to evaluate the relative efficacy of bupivacaine versus ropivacaine for post-operative analgesia using ultrasound-guided TAP block in laparoscopic cholecystectomies. Methods: Sixty adults undergoing elective laparoscopic cholecystectomy were randomised to receive ultrasound-guided TAP block at the end of the surgical procedure with either 0.25% bupivacaine (Group I, n = 30 or 0.375% ropivacaine (Group II, n = 30. All patients were assessed for post-operative pain and rescue analgesic consumption at 10 min, 30 min, 1 h, 4 h, 8 h, 12 h and 24 h time points. Means for normally distributed data were compared using Student′s t-test, and proportions were compared using Chi-square or Fisher′s exact test whichever was applicable. Results: Patients receiving ultrasound-guided TAP block with ropivacaine (Group II had significantly lower pain scores when compared to patients who received the block with bupivacaine (Group I at 10 min, 30 min and 1 h. However, both the drugs were equivalent for post-operative analgesia and 24 h cumulative rescue analgesic requirement (median [interquartile range] (75.00 [75.00-75.00] in Group I vs. 75.00 [75.00-93.75] in Group II, P = 0.366. Conclusion: Ultrasound-guided TAP block with ropivacaine provides effective analgesia in the immediate post-operative period up to 1 h as compared to bupivacaine. However, both the drugs are similar in terms of 24 h cumulative rescue analgesic requirement.

    Full Text Available Background and Aims: Transversus abdominis plane (TAP block and continuous local anaesthetic wound infusion are used as part of multimodal analgesia to treat postoperative pain after lower abdominal surgeries. The aim of this randomised controlled study was to assess the efficacy of the two techniques and compare the two in patients undergoing abdominoplasty. Methods: Ninety female patients undergoing abdominoplasty were allocated to receive continuous wound infusion with saline (control group, GC, n = 30, continuous bilateral TAP block with 0.25% levobupivacaine (group GT, n = 30, or continuous wound infusion with 0.25% levobupivacaine (group GW, n = 30. The primary end-point was morphine requirement in the first 48 h. Numerical rating scale (NRS at rest and during movement, time to first morphine dose and time to first ambulation were recorded. Results: Morphine requirement in the first 48 h was significantly higher in GC than GW and GT (61.9 ± 12.8, 21.5 ± 9.5, and 18.9 ± 8.1 mg, respectively; P = 0.001, but GW and GT were comparable (P = 0.259. NRS was significantly higher in GC during movement in the first 24 h. GW and GT showed significantly longer time to first morphine dose (6.5 ± 1.7 and 8.9 ± 1.4 h, respectively, vs. 1.2 ± 0.3 h in GC and significantly shorter time to first ambulation (7.8 ± 3.1 and 6.9 ± 3.4 h, respectively, vs. 13.2 ± 4.9 h in GC (P = 0.001. Conclusion: Continuous bilateral ultrasound-guided TAP block and continuous local anaesthetic wound infusion significantly decreased total morphine consumption in the first 48 h compared to placebo; however, both treatment techniques were comparable.

    Although laparoscopic colorectal surgery decreases postoperative pain and facilitates a speedier recovery compared with laparotomy, postoperative pain at trocar insertion sites remains a clinical concern. The objective of this study was to assess the effects of a preoperative ultrasound-guided transversus abdominis plane (TAP) block on pain after laparoscopic surgery for colorectal cancer. In total, 58 patients scheduled to undergo laparoscopic surgery following a diagnosis of colorectal cancer were included in this study. The patients were randomized into TAP and control groups; the TAP group patients received a preoperative ultrasound-guided bilateral TAP block with 0.5 mL/kg of 0.25 % bupivacaine, while the control patients received the block with an equal amount of saline. Pain on coughing and at rest was assessed during postanesthetic recovery (PAR; 1 h after surgery) and on postoperative days (PODs) 1 (24 h), 2 (48 h), and 3 (72 h) by an investigator blinded to group allocations using the numeric rating scale (NRS). The primary outcome was pain on coughing on postoperative day (POD) 1. Fifty-five patients were included in the final analysis, including 28 in the TAP and 27 in the control groups. The pain intensity on coughing and at rest during PAR and on PODs 1, 2, and 3 showed no significant differences between groups. Furthermore, there was no significant difference in postoperative opioid consumption, sedation scores, nausea scores at the four time points, complication rates, and length of hospital stay between groups. In colorectal cancer patients undergoing laparoscopic colorectal surgery, a TAP block did not offer enough benefit for clinical efficacy in terms of postoperative pain or analgesic consumption.

    Ultrasound-guided transversus abdominis plane (TAP) block is done as a part of multimodal analgesia for pain relief after abdominal surgeries. This prospective randomized, double-blind, placebo-controlled trial was conducted to evaluate the postoperative analgesic efficacy of bilateral TAP block in patients undergoing midline colorectal surgeries using ropivacaine. Eighty patients scheduled for elective colorectal surgeries involving midline abdominal wall incision under general anesthesia were enrolled in this prospective randomized controlled trial. Group A received TAP block with 20 ml of 0.2% ropivacaine on either side of the abdominal wall, and Group B received 20 ml of normal saline. The time to request for rescue analgesia, total analgesic consumption in 24 h, and satisfaction with the anesthetic technique were assessed. The mean visual analog scale scores at rest and on coughing were higher in control group ( P > 0.05). Time (min) to request for the first rescue analgesia was prolonged in study group compared to control group ( P consumption in 24 h postoperatively was significantly high in control group ( P 0.05). The level of satisfaction concerning postoperative pain control/anesthetic technique was higher in study group ( P < 0.001). TAP block produces effective and prolonged postoperative analgesia in patients undergoing midline colorectal surgery. It is a technically simple block to perform with a high margin of safety. It produces a considerable reduction in mean intravenous postoperative tramadol requirements, reduction in postoperative pain scores, and increased time to first request for further analgesia, both at rest and on movement.

    Transversus abdominis plane (TAP) block is a peripheral nerve block that reduces postoperative pain, nausea, vomiting and the need for postoperative opioids following various types of abdominal surgery. The primary aim of the present study was to evaluate the effects of TAP block on postoperative analgesia and opioid consumption in living liver donors in whom a right "J" abdominal incision was used. This prospective, double-blinded, randomized controlled study was conducted with 50 living liver donors, aged 18-65years, who were scheduled to undergo right hepatectomy. Patients who received ultrasonography-guided subcostal TAP block were allocated into Group 1, and patients who did not receive TAP block were allocated into Group 2. The TAP blocks were performed bilaterally at the conclusion of surgery using 1.5mg∗kg -1 bupivacaine diluted with saline to reach a total volume of 40mL. For each patient, morphine consumption, pain scores at rest and movement, sedation scores, nausea, vomiting and the need for antiemetic medication were assessed at 0, 2, 4, 6, 12 and 24h postoperatively by researchers who were blinded to the study groups. Morphine consumption was significantly lower in Group 1 than in Group 2 at the 2nd, 6th and 24th hours (Pconsumption values after 24h were 40mg and 65mg in Groups 1 and 2, respectively. The TAP block significantly reduced postoperative visual analog scale pain scores both at rest and during movement at 0, 2, 4, 6, and 24h postoperatively (Pconsumption and contributed to analgesia in living liver donors who underwent upper abdominal wall incisions.

    Transversus abdominis plane (TAP) block using a short-acting local anesthetic as part of multimodal analgesia is efficient in various abdominal surgeries, including laparoscopic surgery. However, information regarding its use in laparoscopic colorectal surgery is still limited and sometimes controversial. Therefore, we conducted a systematic review and meta-analysis to determine whether TAP block using a short-acting anesthetic has a positive postoperative analgesic outcome in patients who have undergone laparoscopic colorectal surgery. We searched for studies comparing the postoperative pain outcome after laparoscopic colorectal surgery between patients who received TAP block and a control group (placebo or no treatment). Outcome measures were early pain at rest (numeric rating scale [NRS] score at 0-2 h postoperatively), late pain at movement (NRS score at 24 h postoperatively), late pain at rest (NRS score at 24 h postoperatively), and postoperative opioid consumption (up to 24 h postoperatively). We used a random-effects model for the meta-analysis and Egger's regression test to detect publication bias. We included six studies involving 452 patients (224 in the TAP block group, 228 in the control group). Early and late pain scores at movement were significantly different between the TAP block and control groups (standardized mean difference: - 0.695, P consumption (P = 0.257). The TAP block using a short-acting anesthetic had a significant effect on the postoperative pain outcome in the early (0-2 h) and late (24 h) period at movement. However, it did not have a significant effect on the postoperative pain outcome in the early (0-2 h) and late (24 h) periods at rest after laparoscopic surgery.

    To evaluate the effectiveness of 0.125% bupivacaine compared to 0.25% bupivacaine for ultrasound-guided transversus abdominis plane (TAP) block in patients undergoing open inguinal hernia repair. Randomized, double-blind study. Educational and research hospital. Forty adult patients of American Society of Anesthesiologists physical status I-III undergoing elective primary unilateral open inguinal hernia repair under spinal anesthesia. Patients in group I received 20 mL of 0.25% bupivacaine, whereas patients in group II received 20 mL of 0.125% bupivacaine for TAP block at the end of the surgery. Pain intensity was assessed at rest and during coughing using 10-cm visual analog scale score at 5, 15, 30, and 45 minutes and 1, 2, 4, 6, 12, and 24 hours after TAP block. Morphine consumption and time to first morphine requirement were recorded. Visual analog scale scores at rest and during coughing were not significantly different between groups at all time points measured. Twenty-four hours of morphine consumption (7.72±7.33 mg in group I and 6.06±5.20 mg in group II; P=.437) and time to first morphine requirement (182.35±125.16 minutes in group I and 143.21±87.28 minutes in group II; P=.332) were not different between groups. 0.125% Bupivacaine provides similar analgesic effect compared to 0.25% bupivacaine for ultrasound-guided TAP block in patients undergoing open inguinal hernia repair.

    Full Text Available Background: Transversus abdominis plane (TAP block is a regional anesthesia technique whose efficacy has been proven for postoperative pain relief after cesarean section (CS. Dexamethasone, a glucocorticoid, is now emerging as a new adjunct to local anesthetics for prolonging the duration of action and has been studied in different brachial plexus blocks. The primary outcome was to study the effect of dexamethasone as additive to ropivacaine on the duration of TAP block as assessed by time to first analgesic (TFA . The secondary outcome was total postoperative analgesic consumption, postoperative nausea and vomiting, and patient satisfaction. Method: This RCT was conducted on seventy American Society of Anesthesiology Grade I and II patients undergoing CS under subarachnoid block. Patients were randomly allocated to two groups comprising 35 patients each. Patients in Group I received ultrasound-guided bilateral TAP block at the end of surgery using 40 ml ropivacaine 0.2% and 2 ml saline, and patients in Group II received the block using 40 ml ropivacaine 0.2% and 2 ml (8 mg dexamethasone. Result: TFA was significantly longer in Group II (5.92 ± 1.02 vs. 3.11 ± 0.82 h, P = 0. Group II also had decreased tramadol requirement postoperatively (100.00 ± 0.00 vs. 140.00 ± 50.26 mg, P = 0.046. The incidence of nausea and vomiting was also lower (82.86% vs. 97.14%, P = 0.02318. The patient satisfaction with regard to pain relief was more (57.14% vs. 25.71%, P = 0.038. Conclusion: Addition of dexamethasone to ropivacaine in TAP block prolonged the duration of the block. There was no complication seen with TAP block in any of the patients.

    Full Text Available Background and Aims: Transversus abdominis plane (TAP block has proven to be an effective component of multimodal analgesic regimens for a variety of abdominal procedures. Magnesium sulphate (MgSO4 N-methyl-D-aspartate receptor antagonist has the potential to be an ideal adjuvant in TAP block. We studied the efficacy of MgSO4as an adjuvant to bupivacaine in TAP block in patients scheduled for total abdominal hysterectomy (TAH under subarachnoid block (SAB. Methods: Sixty-five women belonging to American Society of Anesthesiologists physical status 1 or 2, aged between 35 and 70 years, scheduled for TAH under SAB were recruited. Patients in Group B (n = 32 received 18 mL 0.25% bupivacaine (45 mg with 2 mL normal saline (NS, whereas those in Group BM (n = 33 received 18 mL 0.25% bupivacaine (45 mg with 1.5 mL (150 mg MgSO4and 0.5 mL NS in the ultrasound (USG-guided TAP block performed on each side after the completion of the surgery under SAB. They were evaluated for pain at 0, 2, 4, 6, 12 and 24 h, time to first rescue analgesic and duration of postoperative analgesia were noted. Results: The post-operative visual analogue scale (VAS scores were lower in Group BM at 4, 6 and 12 h (P < 0.05. Mean duration of analgesia was significantly prolonged in Group BM with lesser requirement of rescue analgesic (P < 0.05 up to 12 h. Conclusion: MgSO4 (150 mg as an adjuvant to bupivacaine in USG-guided TAP block reduces post-operative pain scores, prolongs the duration of analgesia and decreases demands for rescue analgesics.

    We report a case of mucosa-associated lymphoid tissue (MALT) lymphoma involving the medial rectus muscle in a 47-year-old man along with CT, MRI, 18 F-fluorodeoxy-glucose positron emission tomography/CT ( 18 F-FDG PET/CT), and pathologic features. The lesion was manifested as a fusiform enlargement isolated to the right medial rectus muscle with involvement of its tendinous insertion. The lesion was isoattenuating to the brain on non-enhanced CT images, showing as isointense to gray matter on fast spin echo T1- and T2-weighted images with fat saturation, and showed homogeneous enhancement on contrast-enhanced CT and MR images. The maximum stan- dardized uptake value on 18 F-FDG PET/CT was 4.9 g/mL. The results of histological and immunohistochemical examinations of the specimen obtained by biopsy of the right medial rectus muscle were consistent with MALT lymphoma. It should be noted that the extraocular muscle (EOM) is a rare location for the involvement of MALT lympho- ma, and MALT lymphoma of the EOM may mimic thyroid orbitopathy.

    Full Text Available Background: Different volumes of local anaesthetic are employed in transversus abdominis plane (TAP block to provide analgesia for lower abdominal surgeries. Our aim was to compare the efficacy of high versus low volume of bupivacaine TAP block in providing postoperative analgesia for caesarean sections. Settings and Design: Prospective, single-blind, randomized comparative study was performed during post-operative period. Materials and Methods: Sixty patients who had received spinal anaesthesia for caesarean section were randomly allocated to one of three groups: Group A received 20 ml of 0.25% bupivacaine, Group B received 30 ml of 0.166% bupivacaine on each side TAP block under ultrasound guidance, respectively, and Group C did not receive TAP block. Multi-modal analgesia comprising paracetamol, diclofenac and patient-controlled analgesia (PCA morphine was administered to all patients. The primary outcome measure in our study was 24-h post-operative morphine consumption through intravenous (IV PCA. Other secondary outcome measures were pain scores, nausea, sedation and patient satisfaction scores. Statistical Analysis: Statistical analysis done using analysis of variance, Fisher's Exact test and Kruskal–Wallis test. Results: Our primary outcome measure of 24-h cumulative PCA morphine consumption was 18.2 ± 6.5, 17.9 ± 8.6 and 19.4 ± 8.4 mg in groups A, B and C, respectively (P = 0.819. In the secondary outcome measures, 100% of study population in group A & B and 95% of group C had pain score of 0-3 on Numerical Rating Scale (P = 1.000 at 24 hr. 19, 15 and17 patients in group A, B and C, respectively, agreed and 1, 5 and 3 patients in group A, B and C, respectively, very strongly agreed with patient satisfaction survey for pain management (P = 0.265. Conclusion: TAP block as a part of multi-modal analgesia is debatable in the context of reducing the need of post-operative opioids. The present study was unequivocal in that two different

    The management of Dengue virus infection can be challenging. Varied presentations and numerous complications intrinsic to dengue by itself increase the complexity of treatment and potential mortality. When burdened with the presence of additional comorbidities and the need to continue compulsory medications, clear stepwise definitive guidance is lacking and patients tend to have more complex complications and outcomes calling to question the clinical decisions that may have been taken. The use and continuation of warfarin in dengue virus infection is one such example. We report a 65 year old South Asian female who presented with dengue fever. She had a history bronchial asthma, a prior abdominal surgery, and was on warfarin and maintained a therapeutically appropriate internationalized normalized ratio for a mechanical aortic valve replacement. Though preemptive decision to stop warfarin was taken with decreasing platelet counts, her clinical course was complicated with the development of bilateral rectus sheath haematoma's requiring resuscitation with blood transfusions. Though management of dengue viral fever has seen drastic evolution with recent updated guidance, clinical scenarios seen in the course of the illness still pose challenges to the managing physician. The need to continue obligatory anticoagulation which may seem counterintuitive during a complex disease such as dengue virus infection must be considered after understanding the potential risks versus that of its benefits. Though case by case decisions maybe warranted, a clear protocol would be very helpful in making clinical decisions, as the correct preemptive decision may potentially avert catastrophic and unpredictable bleeding events.

    To evaluate the results of Faden operations on the medial rectus (MR) muscles with or without recession for the treatment of partially accommodative esotropia associated with a high accommodative convergence to accommodation (AC : A) ratio and to determine whether there was a decrease in the effects of posterior fixation over time. In this retrospective study, 108 of 473 patients who underwent surgery for partially accommodative esotropia with a high AC : A ratio received Faden operations on both MR muscles, and 365 received symmetric MR muscle recessions combined with a Faden operation. For the Faden operation, a satisfactory outcome of 76.9% at 1 month postoperation, decreased to 71.3% by the final follow-up visit (mean 4.8 years). A moderate positive correlation was observed between the increase in the postoperative near deviation and postoperative time. For the Faden operations combined with MR recession, a satisfactory outcome of 78.9% at 1 month post-operation, decreased to 78.4% by the final follow-up visit. A Faden operation of the MR muscles with or without recession is an effective surgical option for treating partially accommodative esotropia associated with a high AC : A ratio. For Faden operations of the MR muscles without recession, the effects of the posterior fixation decline over time.

    Full Text Available Rectus sheath hematoma (RSH is an uncommon cause of abdominal pain that can lead to life-threatening bleeding, particularly in elderly patients receiving anticoagulation therapy. Type III RSHs, based on computer tomography (CT evaluation, is characterized by active bleeding with intramuscular or intraperitoneal extension and hemodynamic instability. Medical contemporary knowledge of this condition is contentious and overall 20% of acute mortality has been reported. The purpose of this study was to retrospectively review our experience and outcomes in the management of RSHs treated with percutaneous arterial embolization of the epigastric vessels. We retrospectively analyzed 43 patients with RSH type III, submitted to percutaneous epigastric artery embolization from 2007 to 2015. Percutaneous arterial embolization was feasible and successful in patients with a high burden of comorbidities and receiving anticoagulation therapy. There was no acute mortality and a late mortality at 3 months of 9.1% (4/43 was not directly related to RSHs or arterial embolization. Patients with late mortality had lower ejection fraction, prolonged PTT, greater RDW and warfarin in overlapping with low-molecular-weight heparins. Transcatheter arterial embolization of the epigastric vessels was safe, feasible and effective in stopping the bleeding. Despite anti-platelets/anti-coagulation therapy and a high burden of comorbidities, there was no acute mortality related to RSH.

    Dengue fever is a common mosquito-borne viral illness with a clinical spectrum ranging from a simple febrile illness to potentially life-threatening complications such as dengue hemorrhagic fever and dengue shock syndrome. Dengue infection can affect many organs, including the central nervous system. The neurological manifestations reported in dengue infections are meningitis, encephalitis, stroke, acute disseminated encephalomyelitis, and Guillain-Barré syndrome. We report the cases of two interesting patients with confirmed dengue infection who presented with complications of possible central nervous system vasculitis and cranial nerve palsy. The first patient was a 53-year-old previously healthy Singhalese woman who developed acute-onset slurring of speech and ataxia with altered sensorium 1 day after recovery from a critical period of dengue hemorrhagic fever. Subsequent investigations revealed evidence of encephalopathy with brainstem ischemic infarctions. Her clinical picture was compatible with central nervous system vasculitis. She was treated successfully with intravenous steroids and had a full functional recovery. The second patient was a middle-aged Singhalese woman who had otherwise uncomplicated dengue infection. She developed binocular diplopia on day 4 of fever. An ocular examination revealed a convergent squint in the left eye with lateral rectus palsy but no other neurological manifestation. Central nervous system vasculitis due to dengue infection is a very rare phenomenon, and to the best of our knowledge, only one case of central nervous system vasculitis has been reported to date, in a patient of pediatric age. Cranial nerve palsy related to dengue infection is also rare, and only a few cases of isolated abducens nerve palsy have been reported to date. The two cases described in this report illustrate the rare but important central nervous system manifestations of dengue fever and support the fact that the central nervous system is one of the

La ejecución de este estudio se justificó por el insuficiente conocimiento existente sobre el alineamiento ocular en las endotropías parcialmente acomodativas, luego de aplicar la técnica de debilitamiento bilateral de los músculos rectos medios. En la serie estudiada, la edad media fue de 6,3 años y el alineamiento ocular logrado en el período posoperatorio resultó exitoso, además de que no estuvo relacionado con la ametropía.

The implementation of this study was justified for the insufficient existent knowledge on the ocular alignment in the partially accommodative endotropia, after applying the technique of bilateral attenuation of medial rectus muscles. In the studied series, the mean age was of 6,3 years and the ocular alignment achieved in the posoperative period was successful besides that was not related with the ametropia. The amblyopia found contributed to the prognosis of the disorder.

    We present our management of lower urinary tract (LUT) mesh perforation after mid-urethral polypropylene mesh sling using a novel combination of surgical techniques including total or near total mesh excision, urinary tract reconstruction, and concomitant pubovaginal sling with autologous rectus fascia in a single operation. We retrospectively reviewed the medical records of 189 patients undergoing transvaginal removal of polypropylene mesh from the lower urinary tract or vagina. The focus of this study is 21 patients with LUT mesh perforation after mid-urethral polypropylene mesh sling. We excluded patients with LUT mesh perforation from prolapse kits (n = 4) or sutures (n = 11), or mesh that was removed because of isolated vaginal wall exposure without concomitant LUT perforation (n = 164). Twenty-one patients underwent surgical removal of mesh through a transvaginal approach or combined transvaginal/abdominal approaches. The location of the perforation was the urethra in 14 and the bladder in 7. The mean follow-up was 22 months. There were no major intraoperative complications. All patients had complete resolution of the mesh complication and the primary symptom. Of the patients with urethral perforation, continence was achieved in 10 out of 14 (71.5 %). Of the patients with bladder perforation, continence was achieved in all 7. Total or near total removal of lower urinary tract (LUT) mesh perforation after mid-urethral polypropylene mesh sling can completely resolve LUT mesh perforation in a single operation. A concomitant pubovaginal sling can be safely performed in efforts to treat existing SUI or avoid future surgery for SUI.

    Longitudinal descriptive exploratory study. To evaluate in primigravid women the immediate effect of drawing-in and abdominal crunch exercises on inter-rectus distance (IRD), measured at 4 time points during pregnancy and in the postpartum period. There is scant knowledge of the effect of different abdominal exercises on IRD in pregnant and postpartum women. The study included 84 primiparous participants. Ultrasound images were recorded with a 12-MHz linear transducer, at rest and during abdominal drawing-in and abdominal crunch exercises, at 3 locations on the linea alba. The IRD was measured at 4 time points: gestational weeks 35 to 41, 6 to 8 weeks postpartum, 12 to 14 weeks postpartum, and 24 to 26 weeks postpartum. Separate 2-way, repeated-measures analyses of variance (ANOVAs) were performed for each exercise (drawing-in and abdominal crunch) and each measurement location to evaluate the immediate effects of exercises on IRD at each of the 4 time points. Similarly, 2-way ANOVAs were used to contrast the effects of the 2 exercises on IRD. Performing the drawing-in exercise caused a significant change in width of the IRD at 2 cm below the umbilicus, narrowing the IRD by a mean of 3.8 mm (95% confidence interval [CI]: 1.2, 6.4 mm) at gestational weeks 35 to 41, and widening the IRD by 3.0 mm (95% CI: 1.4, 4.6 mm) at 6 to 8 weeks postpartum, by 1.8 mm (95% CI: 0.6, 3.1 mm) at 12 to 14 weeks postpartum, and by 2.5 mm (95% CI: 1.4, 3.6 mm) at 24 to 26 weeks postpartum (Ppostpartum weeks 24 to 26. The average amount of narrowing varied from 1.6 to 20.9 mm, based on time and location. Overall, there was a contrasting effect of the 2 exercises, with the abdominal crunch exercise consistently producing a significant narrowing of the IRD. In contrast, the drawing-in exercise generally led to a small widening of the IRD.

    Multiple preoperative, intraoperative and postoperative decisions can influence the outcome of microsurgical breast reconstruction. We have simplified the decision-making process by incorporating a number of algorithms into our microsurgical breast reconstruction practice and critically review our results in this study. Prospectively maintained databases for all microsurgical breast reconstructions performed by a single surgeon over a nine-year period were examined to determine: patient demographics; operative details including flap choice, donor and recipient vessel selection; and, details of intraoperative and early postoperative (406 Consecutive free flap microsurgical breast reconstructions (164 unilateral and 121 bilateral) were performed in 285 patients over the study period. Deep inferior epigastric artery perforator (DIEP) flaps (88%, n=359) were used most commonly followed by muscle-sparing transverse rectus abdominis musculocutaneous (MS-TRAM) flaps (11%, n=44), and fascial-sparing TRAM (FS-TRAM) flaps (0.7%, n=3). One-hundred-seventy-one (48%) DIEP flaps were based on a single perforator while 188 (52%) had multiple perforators. The internal mammary (IM) artery and vein were used as the recipient vessels for 99% (n=403) of flaps. A second venous anastomosis was required for 11.8 percent (n=48) of flaps. Partial flap failure occurred in nine (2.2%) flaps while total flap failure occurred in two flaps (0.5%). Minimum follow-up was three months. Incorporating a number of algorithms into our practice has enabled us to simplify the decision-making processes involved in microsurgical breast reconstruction and to consistently obtain successful surgical outcomes.

    Full Text Available Abstract Background Skin Sparing Mastectomy (SSM and immediate breast reconstruction has become increasingly popular as an effective treatment for patients with breast carcinoma. The aim of this study was to evaluate the clinical outcome of skin sparing mastectomy in early breast cancer at a single population-based institution. Methods Records of ninety-five consecutive patients with operable breast cancer who had skin-sparing mastectomy and immediate breast reconstructions between 1995 and 2003 were reviewed. Patient and tumor characteristic, type of reconstruction, postoperative complications, aesthetic results and incidence of recurrence were analyzed. Results Mean age of the patients was 51.6(range 33–72 years. The AJCC pathologic stages were 0 (n = 51, 53.7%, I (n = 20, 21.1%, and II (n = 2, 2.1%. Twenty of the patients had recurrent disease (21.1%. The immediate breast reconstructions were performed with autologus tissue including latissimus dorsi musculocutaneous flap in 63 (66.3% patients and transverse rectus abdominis myocutaneous (TRAM flap in 4 (4.2% patients. Implants were used in 28 (29.4% patients. The average hospital stay was 7.7 days. Flap complication occurred in seven (10.4% patients resulting in four (6% re-operations and there were no delay in accomplishing postoperative adjuvant therapy. At a median follow-up of 69 months (range 48 to 144, local recurrence was seen in one patient (1.1% and systemic recurrence was seen in two patients (2.1%. Conclusion Skin sparing mastectomy and immediate breast reconstruction for early breast cancer is associated with low morbidity and low rate of local recurrence.

    Sarcomas are a rare complication of radiotherapy for breast cancer and such patients have a poor prognosis. We report resection of an osteosarcoma in the chest wall that developed 20 years after postoperative radiotherapy for breast cancer. A 57-year-old woman was referred to our department for examination and treatment of an anterior chest wall tumor in April 2007. In September 1986, she had undergone a radical mastectomy and postoperative irradiation and chemotherapy for right breast cancer. In December 2003, she underwent chemotherapy for recurrence of breast cancer which was pointed out on computed tomography involving the pleura and left superior clavicular lymph nodes. In March 2006, follow-up computed tomography of the chest demonstrated the destruction of the sternum, which was diagnosed as recurrence and she was followed with chemotherapy for breast cancer continuously thereafter. In April 2007, because of the developing sternal tumor, excisional biopsy was performed and histopathology indicated sarcoma. In May 2007, resection of the chest wall tumor with the sternum, bilateral clavicles, bilateral first and second ribs, and right partial lung (upper and middle lobe) were performed, and the chest wall defect was reconstructed with a rectus abdominis musculocutaneous free flap. Histopathologically, the tumor was osteosarcoma with margin free. Adjuvant radiotherapy to the breast plays a significant role in preventing local disease recurrence in women treated for breast cancer. However, radiotherapy can induce malignant sarcoma after a latency period of several years. The risk is extremely low for the individual patient, but this disease is aggressive and associated with a poor overall prognosis. Therefore, early detection is necessary for optimal treatment and incisional biopsy is necessary for accurate diagnosis. (author)

    Surgery for carcinoma of the oral cavity has developed rapidly with recent advances in reconstruction. Particularly, in radical surgery for progressive and recurrent disease, safe and adequate resection has been made possible and postoperative cosmetic and functional recovery has been achieved. We reviewed 64 patients with progressive and recurrent cancer who had undergone reconstruction using microvascular techniques during the 12 years from 1983 to 1994. There were 19 patients with T3 disease, 25 with T4 disease, and 20 with recurrence. The free grafts used were radial forearm flaps, the jejunum, rectus abdominis musculocutaneous flaps, and scapular flaps. The survival of free flap grafts was 95.3%. The primary tumor control rate was 85.9%, and the 5-year cumulative survival rate was 61.1%, 60.1%, and 62.9% for patients with T3, T4, and recurrent disease, respectively. Twelve patients with T4 disease of the tongue and the floor of the mouth were treated with combined preoperative brachytherapy and surgery to alleviate postoperative dysfunction, and this treatment was found to be exceedingly effective for improving the postoperative quality of life. There are still many problems with mandibular reconstruction. Since cancer patients commonly undergo preoperative radiotherapy, transplantation of living vascularized bone grafts is frequently performed and is believed to be effective. Since it is important to reconstruct masticatory function as well as to achieve cosmetic improvement, various techniques have recently been used to fit the reconstructed mandible with dental prostheses in order to restore masticatory function. This paper describes the present status and the prospects of surgical therapy for oral cancer. (author)

    In postmastectomy reconstruction, procedure choice is heavily influenced by the relative risks of the various options. This study sought to evaluate complications in a large, multicenter patient population. Previous studies have reported widely varying complication rates, but have been limited by their single center designs and inadequate controlling for confounders in their analyses. Eleven sites enrolled women undergoing first time, immediate, or delayed reconstruction following mastectomy for cancer treatment or prophylaxis. Procedures included expander/implant, latissimus dorsi (LD), pedicle transverse rectus abdominis musculocutaneous (PTRAM), free TRAM (FTRAM), and deep inferior epigastric perforator (DIEP) techniques. Data were gathered pre- and postoperatively from medical records. Separate logistic regressions were conducted for all complications and major complications (those requiring rehospitalization and/or reoperation) within 1 year. Odds ratios (ORs) were calculated for procedure type, controlling for site, demographic, and clinical variables. Complication rates for 2234 patients were analyzed. Compared with expander/implant reconstructions, LD (OR) 1.95, P = 0.026), PTRAM (OR 1.89, P = 0.025), FTRAM (OR 1.94, P = 0.011), and DIEP (OR 2.22, P procedures were associated with higher risks of complications. Significantly higher risks were also associated with older age, higher body mass index (BMI), immediate reconstruction, bilateral procedures, and radiation. For major complications, regression showed significantly greater risks for PTRAM (OR 1.86, P = 0.044) and DIEP (OR 1.75, P = 0.004), than expander/implant reconstructions. Failure rates were relatively low, ranging from 0% for PTRAM to 5.9% for expander/implant reconstructions. In this multicenter analysis, procedure choice and other patient variables were significant predictors of 1-year complications in breast reconstruction. These findings should be considered in counseling patients on

    Ultrasonography (USG)-guided transversus abdominis plane (TAP) block is an abdominal field block with high efficacy. This study was undertaken with the aim of determining the effect of the addition of dexamethasone to 0.5% ropivacaine on post-operative analgesia in USG-guided TAP block for inguinal hernia repair. A double-blind randomised control study was conducted on sixty patients posted for inguinal hernia repair with the American Society of Anesthesiologists physical Status I or II, who were allocated two groups of 30 each. Patients in Group RS received 0.5% ropivacaine (20 ml) and normal saline (2 ml) whereas patients in Group RD received 0.5% ropivacaine (20 ml) and dexamethasone (2 ml, i.e., 8 mg), in USG-guided TAP Block on the same side, after repair of inguinal hernia under spinal anaesthesia. Visual analogue scale (VAS) scores, time for request of first analgesia and total tramadol consumption in first 24 h were compared. Unpaired Student's t -test and Mann-Whitney U-test were performed using SPSS 23 Software. Patients in Group RD had significantly lower VAS scores as compared to Group RS from 4 th to 12 th h, postoperatively. Duration of analgesia was significantly more in Group RD (547.50 [530,530] min) when compared with Group RS (387.50 [370,400] min) ( P consumption.

    The purpose of this study was to compare the effects of lateral abdominal transversus abdominis plane block (TAP block) and iliohypogastric/ilioinguinal nerve block (IHINB) under ultrasound guidance for postoperative pain management of inguinal hernia repair. Secondary purposes were to compare the complication rates of the two techniques and to examine the effects of TAP block and IHINB on chronic postoperative pain. This was a prospective randomized controlled open-label study. After approval of the Research Ethics Board, a total of 90 patients were allocated to three groups of 30 by simple randomized sampling as determined with a priori power analysis. Peripheral nerve blocks (TAP block or IHINB) were administered to patients following subarachnoid block according to their allocated group. Patient pain scores, additional analgesic requirements and complication rates were recorded periodically and compared. Pain scores were significantly lower in the study groups (p block group [GT] 266.6 ± 119.7 min; IHINB group [GI] 247.2 ± 128.7 min; and control group [GC] 79.1 ± 66.2 min; p block or IHINB for patients undergoing inguinal herniorrhaphy reduces the intensity of both acute and chronic postoperative pain and additional analgesic requirements.

    Transversus abdominis plane (TAP) block provides effective postoperative analgesia after abdominal surgeries. It can be also a useful strategy to reduce perioperative opioid consumption, support intraoperative hemodynamic stability, and promote early recovery from anesthesia. The aim of this prospective randomized double-blind study was to assess the effect of subcostal TAP blocks on perioperative opioid consumption, hemodynamic, and recovery time in living liver donors. The prospective, double-blinded, randomized controlled study was conducted with 49 living liver donors, aged 18-65 years, who were scheduled to undergo right hepatectomy. Patients who received subcostal TAP block in combination with general anesthesia were allocated into Group 1, and patients who received general anesthesia alone were allocated into Group 2. The TAP blocks were performed bilaterally by obtaining an image with real-time ultrasound guidance using 0.5% bupivacaine diluted with saline to reach a total volume of 40 mL. The primary outcome measure in our study was perioperative remifentanil consumption. Secondary outcomes were mean blood pressure (MBP), heart rate (HR), mean desflurane requirement, anesthesia recovery time, frequency of emergency vasopressor use, total morphine use, and length of hospital stay. Total remifentanil consumption and the anesthesia recovery time were significantly lower in Group 1 compared with Group 2. Postoperative total morphine use and length of hospital stay were also reduced. Changes in the MAP and HR were similar in the both groups. There were no significant differences in HR and MBP between groups at any time. Combining subcostal TAP blocks with general anesthesia significantly reduced perioperative and postoperative opioid consumption, provided shorter anesthesia recovery time, and length of hospital stay in living liver donors. © 2017 John Wiley & Sons A/S.

    Full Text Available Background and Aims: Both transversus abdominis plane (TAP block and combined ilioinguinal-iliohypogastric (IIN/IHN blocks are used routinely under ultrasound (USG guidance for postoperative pain relief in patients undergoing inguinal hernia surgery. This study compares USG guided TAP Vs IIN/IHN block for post-operative analgesic efficacy in adults undergoing inguinal hernia surgery. Methods: Sixty adults aged 18 to 60 with American Society of Anesthesiologsts' grade I or II were included. After general anaesthesia, patients in Group I received USG guided unilateral TAP block using 0.75% ropivacaine 3 mg/kg (maximum 25 mL and those in Group II received IIN/IHN block using 10 mL 0.75% ropivacaine. Postoperative rescue analgesia was with tramadol (intravenous IV ± diclofenac IV in the first 4 h followed by oral diclofenac subsequently. Total analgesic consumption in the first 24 h was the primary objective, intraoperative haemodynamics, number of attempts and time required for performing the block as well as the postoperative pain scores were also evaluated. Results: Time to first analgesic request was 319.8 ± 115.2 min in Group I and 408 ± 116.4 min in Group II (P = 0.005. Seven patients (23.33% in Group I and two (6.67% in Group II required tramadol in first four hours. No patient in either groups received diclofenac IV. The average dose of tablet diclofenac was 200 ± 35.96 mg in Group I and 172.5 ± 34.96 mg in Group II (P = 0. 004. Conclusion: USG guided IIN/IHN block reduces the postoperative analgesic requirement compared to USG guided TAP block.

O procedimento cirúrgico levou estes fatos em consideração, tendo-se optado por um retrocesso pequeno do reto inferior para que se corrigisse o torcicolo sem interferir na posição de leitura. Os resultados pós-operatórios foram satisfatórios.A case report of an atipical inferior rectus congenital fibrosis associated with a generalized muscular hypotonia is presented. It shows mild hipotropia with a normal visual acuity and binocularity in infraversion position contrasting with the severe hipotropia and ambliopy found. The surgical procedure took these facts into consideration, so we performed a small retrocess of the muscle with the objective to correct the head position without changes in the reading position. The postoperative results were satisfactory.

    It remains unknown whether continuous or scheduled intermittent bolus local anesthetic administration is preferable for transversus abdominis plane (TAP) catheters. We therefore tested the hypothesis that when using TAP catheters, providing local anesthetic in repeated bolus doses increases the cephalad-caudad cutaneous effects compared with a basal-only infusion. Bilateral TAP catheters (posterior approach) were inserted in 24 healthy volunteers followed by ropivacaine 2 mg/mL administration for a total of 6 hours. The right side was randomly assigned to either a basal infusion (8 mL/h) or bolus doses (24 mL administered every 3 hours for a total of 2 bolus doses) in a double-masked manner. The left side received the alternate treatment. The primary end point was the extent of sensory deficit as measured by cool roller along the axillary line at hour 6 (6 hours after the local anesthetic administration was initiated). Secondary end points included the extent of sensory deficit as measured by cool roller and Von Frey filaments along the axillary line and along a transverse line at the level of the anterior superior iliac spine at hours 0 to 6. Although there were statistically significant differences between treatments within the earlier part of the administration period, by hour 6 the difference in extent of sensory deficit to cold failed to reach statistical significance along the axillary line (mean = 0.9 cm; SD = 6.8; 95% confidence interval -2.0 to 3.8; P = .515) and transverse line (mean = 2.5 cm; SD = 10.1; 95% confidence interval -1.8 to 6.8; P = .244). Although the difference between treatments was statistically significant at various early time points for the horizontal, vertical, and estimated area measurements of both cold and mechanical pressure sensory deficits, no comparison remained statistically significant by hour 6. No evidence was found in this study involving healthy volunteers to support the hypothesis that changing the local anesthetic

    A quantitative observational laboratory study was conducted to characterize and classify core training exercises executed in a suspension modality on the base of muscle activation. In a prospective single-group repeated measures design, seventeen active male participants performed four suspension exercises typically associated with core training (roll-out, bodysaw, pike and knee-tuck). Surface electromyographic signals were recorded from lower and upper parts of rectus abdominis, external oblique, internal oblique, lower and upper parts of erector spinae muscles using concentric bipolar electrodes. The average rectified values of electromyographic signals were normalized with respect to individual maximum voluntary isometric contraction of each muscle. Roll-out exercise showed the highest activation of rectus abdominis and oblique muscles compared to the other exercises. The rectus abdominis and external oblique reached an activation higher than 60% of the maximal voluntary contraction (or very close to that threshold, 55%) in roll-out and bodysaw exercises. Findings from this study allow the selection of suspension core training exercises on the basis of quantitative information about the activation of muscles of interest. Roll-out and bodysaw exercises can be considered as suitable for strength training of rectus abdominis and external oblique muscles.

    This study investigated the effects of age and inactivity due to being chronically bedridden on atrophy of trunk muscles. The subjects comprised 33 young women (young group) and 41 elderly women who resided in nursing homes or chronic care institutions. The elderly subjects were divided into two groups: independent elderly group who were able to perform activities of daily living involving walking independently (n = 28) and dependent elderly group who were chronically bedridden (n = 13). The thickness of the following six trunk muscles was measured by B-mode ultrasound: the rectus abdominis, external oblique, internal oblique, transversus abdominis, thoracic erector spinae (longissimus) and lumbar multifidus muscles. All muscles except for the transversus abdominis and lumbar multifidus muscles were significantly thinner in the independent elderly group compared with those in the young group. The thicknesses of all muscles in the dependent elderly group was significantly smaller than that in the young group, whereas there were no differences between the dependent elderly and independent elderly groups in the muscle thicknesses of the rectus abdominis and internal oblique muscles. In conclusion, our results suggest that: (1) age-related atrophy compared with young women was less in the deep antigravity trunk muscles than the superficial muscles in the independent elderly women; (2) atrophy associated with chronic bed rest was more marked in the antigravity muscles, such as the back and transversus abdominis.

    To investigate the expression of tumor necrosis factor-like weak inducer of apoptosis (TWEAK) in the serum and the rectus abdominis muscle in patients with gastric cancer and its relationship with the nutritional status. Method Clinical data of 102 patients with gastric cancer (gastric cancer group) and 53 patients with benign abdominal disease (control group) who were admitted to Zhejiang Province People's Hospital from January 2008 to October 2013 were analyzed retrospectively. Enzyme-linked immunosorbent assay(ELISA) was used to detect the serum expression of TWEAK. Reverse transcription polymerase chain reaction (RT-PCR) and Western blot were used to detect the mRNA and protein expression of TWEAK in the rectus abdominis muscle. Relationship between TWEAK expression and nutritional status of gastric cancer patients was examined. The relative expression level of TWEAK protein in serum of gastric cancer group and control group was 0.403±0.065 and 0.148±0.036 respectively. The relative expression of TWEAK mRNA in the rectus abdominis muscle tissue was 0.313±0.089 (gastric cancer group) and 0.118±0.005 (control group). The relative expression of TWEAK protein in the rectus abdominis muscle tissue was 0.197±0.064 (gastric cancer group) and 0.066±0.014 (control group), and the differences were statistically significant (both P=0.000). The high expression of TWEAK (high than median) in rectus abdominis muscle of gastric cancer patients was related to the percentage of more than 10% decline in body weight (P=0.000), the small percentage of ideal body weight at the time of admission (P=0.000), BMInutritional risk screening score (P=0.000), lower prognostic nutrition index (P=0.000) and serum albumin gastric cancer patients up-regulates compared to non-tumor patients. The expression level of TWEAK in the rectus abdominis muscle of gastric cancer patients is closely related to poor nutritional status, suggesting that TWEAK may play a key role in the process of

    The pedicled transverse rectus abdominis myocutaneous (TRAM) flap procedure is still widely used for breast reconstruction. The repair of the flap harvest site in the transverse rectus abdominis muscle and sheath is often assisted by the use of prosthetic meshes. This decreases the risk of abdominal wall weakness and herniation but, being a foreign body, it also carries the risk of infection. In this report, we describe the case of a 63-year-old patient who, whilst receiving chemotherapy for metastatic breast cancer, presented with an infected polytetrafluoroethylene mesh 15 years after pedicled TRAM flap immediate breast reconstruction. This necessitated mesh removal to treat the infection. Following a thorough review of the English literature, this is the longest recorded presentation of an abdominal prosthetic mesh infection. The mechanism and aetiology of such a late complication are discussed.

    To retrospectively determine the sensitivity and specificity of magnetic resonance (MR) imaging findings in patients with clinical athletic pubalgia, with either surgical or physical examination findings as the reference standard. Institutional review board approval was granted for this HIPAA-compliant study, and informed consent was waived. MR imaging studies in 141 patients (134 male patients, seven female patients; mean age, 30.1 years; range, 17-71 years) who had been referred to a subspecialist because of groin pain were reviewed for findings including hernia, pubic bone marrow edema, secondary cleft sign, and rectus abdominis and adductor tendon injury. MR imaging findings were compared with surgical findings for 102 patients, physical examination findings for all 141 patients, and MR imaging findings in an asymptomatic control group of 25 men (mean age, 29.8 years; range, 18-39 years). Sensitivity and specificity of MR imaging for rectus abdominis and adductor tendon injury were determined by using a chi(2) analysis, and significance of the findings was analyzed with an unpaired Student t test. Disease patterns seen at MR imaging were compared with those reported in the surgical and sports medicine literature. One hundred thirty-eight (98%) of 141 patients had findings at MR imaging that could cause groin pain. Compared with surgery, MR imaging had a sensitivity and specificity, respectively, of 68% and 100% for rectus abdominis tendon injury and 86% and 89% for adductor tendon injury. Injury in each of these structures was significantly more common in the patient group than in the control group (P pubalgia, including rectus abdominis insertional injury, thigh adductor injury, and articular diseases at the pubic symphysis (osteitis pubis).

    The main position of the working population is becoming sitting. Immobile prolonged sedentary time may cause negative effects including reduced intervertebral discs nutrition. Main ways of mitigating them are regular position changes and exercising. To evaluate influence of the short term training on unstable training machine on balance control and trunk muscles activity in patients with lower back pain. Participants (n=16) experiencing lower back pain were trained on an unstable sculling machine "Rehabili". Their balance tested by (Biodex Balance System) and rectus abdominis, externus oblique, transverse abdominis, multifidus and erector spine muscles activity (measured by surface electromyography) while sitting and standing with usual and aligned body postures both before and after six weeks of training (three 15 minutes sessions per week) were compared in between. Balance control improved after the training program. Besides, more symmetrical activation of both sides rectus and transversus abdominis muscles, as well as increased transversus abdominis muscle activation of 19% (p< 0.05), were observed. Six weeks short sessions training on unstable training machine improved balance control and increased trunk muscles activity especially in aligned body posture when standing or sitting on unstable surface.

    2016-06-01

    [Purpose] This study investigated the effect of exhalation exercises on trunk muscle activity and Oswestry Disability Index by inducing trunk muscle activity through increasing intra-abdominal pressure and activating muscles, contributing to spinal stability. [Subjects and Methods] This intervention program included 20 male patients with chronic low back pain. A total of 10 subjects each were randomly assigned to an exhalation exercise group as the experimental group and a spinal stabilization exercise group as the control group. [Results] There were significant differences in the activities of the rectus abdominis, transverse abdominis, external oblique abdominal, and erector spinae muscles as well as in the Oswestry Disability Index within the experimental group. There were meaningful differences in the activities of the rectus abdominis, external oblique abdominal, and erector spinae muscles and in the Oswestry Disability Index within the control group. In addition, there was a meaningful intergroup difference in transverse abdominis muscle activity alone and in the Oswestry Disability Index. [Conclusion] The breathing exercise effectively increased muscle activity by training gross and fine motor muscles in the trunk. Moreover, it was verified as a very important element for strengthening body stability because it both released and prevented low back pain.

    [Purpose] The purpose of this study was to investigate the relationship between muscle activity and gait function following aquatic trunk exercise in hemiplegic stroke patients. [Subjects and Methods] This study's participants included thirteen hemiplegic patients (ten males and three females). The aquatic therapy consisted of administering concentrative aquatic therapy for four weeks in a therapeutic pool. Gait parameters were measured using a gait analysis system adjusted to each subject's comfortable walking speed. Electromyographic signals were measured for the rectus abdominis, external abdominal oblique, transversus abdominis/internal-abdominal oblique, and erector spine of each patients. [Results] The pre- and post-training performances of the transversus abdominis/internal-abdominal oblique were compared statistically. There was no statistical difference between the patients' pre- and post-training values of maximal voluntary isometric contraction of the rectus abdominis, but the external abdominal oblique values tended to improve. Furthermore, gait factors improved significantly in terms of walking speeds, walking cycles, affected-side stance phases, affected-stride lengths, and stance-phase symmetry indices, respectively. [Conclusion] These results suggest that the trunk exercise during aquatic therapy may in part contribute to clinically relevant improvements in muscle activities and gait parameters.

    Full Text Available This study compares surface electromyographic activity of the internal oblique, rectus abdominis, multifidus, iliocostalis, anterior deltoids during the pull-up on a lower and on a higher difficulty level. We assessed nine adults with previous experience in Pilates. The root mean square (RMS values were normalized by maximum isometric contraction for each participant. During the ascent phase, the low spring position showed a significantly higher RMS than the high spring position of 8.9% for deltoid, 17.2% for internal oblique, 22.3% for rectus abdominis, 4.1% for iliocostalis, and 5.6% for multifidus, and in the descent phase, the RMS in the lower spring exceeded significantly the high spring position in 1.6% for the deltoid, 10% for internal oblique, 31.4% for rectus abdominis and 11.4% for iliocostalis. There was no predominance of abdominal muscles over the shoulder muscle in any spring position. The pull-up exercise can be a useful choice for the core and anterior deltoid muscles strengthening.

    Full Text Available The purpose of this study was to analyze upper extremity and core muscle activation when performing push-ups with different suspension devices. Young fit male university students (n = 29 performed 3 push-ups each with 4 different suspension systems. Push-up speed was controlled using a metronome and testing order was randomized. Average amplitude of the electromyographic root mean square of Triceps Brachii, Upper Trapezius, Anterior Deltoid, Clavicular Pectoralis, Rectus Abdominis, Rectus Femoris, and Lumbar Erector Spinae was recorded. Electromyographic signals were normalized to the maximum voluntary isometric contraction (MVIC. Electromyographic data were analyzed with repeated-measures analysis of variance with a Bonferroni post hoc. Based upon global arithmetic mean of all muscles analyzed, the suspended push-up with a pulley system provided the greatest activity (37.76% of MVIC; p < 0.001. Individually, the suspended push-up with a pulley system also provided the greatest triceps brachii, upper trapezius, rectus femoris and erector lumbar spinae muscle activation. In contrast, more stable conditions seem more appropriate for pectoralis major and anterior deltoid muscles. Independent of the type of design, all suspension systems were especially effective training tools for reaching high levels of rectus abdominis activation.

Electromyographic analysis assessed the multifidus, external oblique, internal oblique, and rectus abdominis muscles during classical Pilates exercises (single leg stretch, criss-cross, and dead bug). We calculated the root mean square normalized by maximum voluntary contraction, and the time of peak activation was provided by a linear envelope and normalized by the total movement cycle. The criss-cross exercise presented the highest values of root mean square for trunk flexors (rectus abdominis and oblique) compared with the other exercises, followed by the single leg stretch and the dead bug, which had similar muscle activation. The single leg stretch presented more activation of the rectus abdominis and oblique, whereas the criss-cross and dead bug created more activation of the oblique compared with the multifidus and rectus. The Pilates exercises presented different muscle recruitment patterns, and allowed the activation of the lumbopelvic stabilizing muscles even in the first session for healthy individuals and those with chronic low back pain.

    CT were performed in thirteen patients (12 women, 1 man) aged from 53 to 90 (mean age, 74) with severe RSH. Five patients also underwent ultrasound examination and three MR examination. Nine patients (69%) were receiving subcutaneous injection of heparin, three (23%) oral anticoagulant therapy and one continuous IV infusion of heparin. Clinical diagnosis was reached in 6 cases. Excessive activity of anticoagulant therapy was noted in 4 cases. The location of the RSH, their densities and their signals were analysed. All the RSH were mostly developed in the lower third of the abdominal wall, had a large spreading into the Retzius space and compressed the bladder and/or the bowels. RSH were all hyperdense and in 8 cases (61%) a fluid-fluid level due to the hematocrit effect was noted. In one case, a retroperitoneal hematoma was discovered. The extension of the RSH was well delineated with MRI. The RSH showed itself with heterogeneous signal intensities with areas of high-signal-intensity on T1-weighted images. Fluid-fluid levels and a concentric ring sign were also noted. Older women with subcutaneous injection of heparin are especially prone to RSH even though there is no overall excessive activity of anticoagulant therapy. Clinical and biological diagnosis may be difficult. CT scan is the exam of choice to reach a precise and acute diagnosis of RSH. (authors). 34 refs., 8 figs

    Full Text Available The purpose of this study was to verify the electromyographic activity of the rectus abdominis and obliquus externus abdominis during abdominal crunch exercise performed with maximum and submaximum loads. Thirteen male and female university students participated in this investigation (18-23 years old. The subjects completed abdominal crunch exercise until exhaustion with 20, 40, 60 and 80% of the maximum load. The root-mean-square (RMS from electromyography activity of the rectus abdominis and obliquus externus muscles from the first and last three repetitions from each workload performed was analyzed. RMS for the last repetitions increased in relation to the first repetitions for the 20% workload, first two repetitions on 40% workload and first repetition on the 80% workload. There was no difference for the 60% workload. Results showed that external load on abdominal crunch exercise might be an alternative to increase intensity while performing abdominal crunch exercise, which on its turn can be a practical tool for subjects that aim to increase abdominal strength level.

    Full Text Available Myoplasties of the extraocular muscle may cause adhesions between the operated muscle and the adjacent tissues, commonly generating cicatricial strabismus. With the purpose of reducing to a minimum the occurrence of adhesion, the effects of mitomycin C, an antifibrotic agent, were studied in concentrations of 0.008%, 0.02%, and 0.04% applied during intraoperative of myoplasties of the superior rectus muscle of rabbits. Fifty six animals were divided in five groups. During the postoperative, the operated areas were washed with physiological solution. Eye drop instillation to prevent inflammation and bacterial infection were used. The method to analyze the results consisted of clinical and histological evaluation and statistical analyzes. We also evaluated at the same time the amount of basic fibroblast growth factor (FGF-2 by immunohistochemical study. Clinically, more adhesions were found in the eyes of the control group than in the groups of treated eyes. However there was no significant statistics difference between the two groups (P>0.05. Histologically, mitomycin C caused a delayed cicatrization in the mioplastic areas, specially in the group who received the 0.02% concentration. The immunohistochemical showed FGF-2 marking in fibroblasts and macrophages, but between the groups there wasn't no difference. Based on those results, mitomycin C in the utilized concentrations was capable of delaying the cicatrization and consequently avoid the secondary strabismus without undesirable side effects.Mioplastias da musculatura extra-ocular podem ensejar aderências entre o músculo operado e os tecidos adjacentes, produzindo, não raro, estrabismos cicatriciais.

    Sports hernias, or athletic pubalgia, is common in athletes, and primarily involves injury to the fascia, muscles, and tendons of the inguinal region near their insertion onto the pubic bone. However, management varies widely, and rectus and adductor tenotomies have not been adequately described. The purpose of this manuscript is to demonstrate a suture repair and a rectus and adductor longus tenotomy technique for sports hernias. After magnetic-resonance-imaging confirmation of sports hernias with rectus and adductor tendonitis, 22 patients underwent a suture herniorrhaphy with adductor tenotomy. The procedure is performed through a 4-cm incision, and a fascial release of the rectus abdominis and adductor tenotomy is performed to relieve the opposing vector forces on the pubic bone. All 22 patients returned to their respective sports and regained their ability to perform at a high level, including professional status. No further surgery was required. In athletes with MRI confirmation of rectus and adductor longus injuries, tenotomies along with a herniorraphy may improve outcomes. A suture repair to reinforce the inguinal floor prevents mesh-related complications, especially in young athletes.

    ção aeróbica, com conseqüente aumento do percentual de fibras oxidativas, induzindo maior resistência à fadiga.The objective of the present study was to evaluate the influence of swimming exercise on metabolic and contractile abilities of rectus of abdomen and the paraesternal intercostal muscle fibers. Adult Wistar rats were initially submitted to an adaptation period and then divided into control and exercise groups. Exercised animals were submitted to swimming for 15, 30, 45, and 60 days, 1 hr/day, 5days/week. At the end of each period, the animals were killed. Small segments of the above muscles were frozen in N-hexane at -70ºC, pre-cooled with liquid nitrogen for two minutes. Histological transverse sections (7 µm were obtained in a cryostat microtome at -20ºC. Some serial sections were stained with HE. Subsequent sections were reacted for NADH-TR to evaluate the oxidizing capacity, and for m-ATPase, after acid and alkaline pre-incubations mediums. Under microscopic examination, the frequencies of fiber types were sampled. Muscle fibers revealed to be grouped in different fascicles, presenting polygonal outlines, with different diameters. Three kind of fibers were detected: SO (slow oxidative, FOG (fast oxidative glycolytic and FG (fast glycolytic, presenting a mosaic pattern distribution. The analysis of the results demonstrated that after 60 days of exercise, the abdominal muscles showed a significant increase in the frequency of SO fibers. After 15 days, a significant decrease in frequency of intermediate FOG fibers and an increase of FG fibers. The paraesternal intercostal muscles revealed a significant increase in the percentage of SO fibers in the 60 day-exercised animals, a percentage increase of FOG fibers in the animals of 45 and 60 days, and a percentage decrease of FG fibers in those of 30, 45 and 60 days. So, due to hydrostatic pressure in swimming exercise, the degree of work was greater in the inspiration muscles. This increase was parallel with

    Athletic pubalgia is a syndrome of chronic lower abdomen and groin pain that occurs in athletes. It is the direct result of stress and microtears of the rectus abdominis inserting on the pubis from the antagonizing adductor longus muscles, and weakness of the posterior transversalis fascia and bulging of the inguinal floor. Under IRB approval, we conducted a retrospective review of our prospectively competitive athlete patients with athletic pubalgia from 2007 to 2013. A cohort of 54 patients was examined. Mean age was 22.4 years. Most patients were football players (n = 23), triathlon (n = 11), track and field (n = 6), soccer players (n = 5), baseball players (n = 4), swimmers (n = 3), golfer (n = 1), and tennis player (n = 1). Fifty one were males and three were females. All patients failed medical therapy with physiotherapy prior to surgery. 76 % of patients had an MRI performed with 26 % having a right rectus abdominis stripping injury with concomitant strain at the adductor longus musculotendinous junction. 7 % of patients had mild nonspecific edema in the distal bilateral rectus abdominis muscles without evidence of a tear. Twenty patients had no findings on their preoperative MRI, and only one patient was noted to have an inguinal hernia on MRI. All patients underwent laparoscopic totally extraperitoneal inguinal hernia repair with synthetic mesh and ipsilateral adductor longus tenotomy. All patients were able to return to full sports-related activity in 24 days (range 21-28 days). One patient experienced urinary retention and another sustained an adductor brevis hematoma 3 months after completion of rehabilitation and surgical intervention. Mean follow up was 18 months. Athletic pubalgia is a disease with a multifactorial etiology that can be treated surgically by a laparoscopic totally extraperitoneal hernia repair with synthetic mesh accompanied with an ipsilateral adductor longus tenotomy allowing patients to return to sports-related activity early with

    Full Text Available Acenocoumarol is a vitamin K antagonist that is used for the treatment of acquired and congenital, both arterial and venous, thrombotic diseases. Its use is complicated by the narrow therapeutic range. Bleeding following oral anticoagulation, despite rare, remains the major complication. Most cases of hemorrhagic episodes usually require short hospitalization and transfusion, while surgical drainage of the hematoma is not recommended. However, in cases that conservative treatment isn’t successful, surgical intervention remains an option. We present a case of severe spontaneous bleeding of the rectus abdominis muscle which was successfully managed surgically.

    Magnetic resonance imaging (MRI) has become the standard imaging modality for activity-related groin pain. Lesions, including rectus abdominis/adductor aponeurosis injury and osteitis pubis, can be accurately identified and delineated in patients with clinical conditions termed athletic pubalgia, core injury, and sports hernia. A dedicated noncontrast athletic pubalgia MRI protocol is easy to implement and should be available at musculoskeletal MR imaging centers. This article will review pubic anatomy, imaging considerations, specific lesions, and common MRI findings encountered in the setting of musculoskeletal groin pain. Copyright © 2013 Elsevier Inc.

    Athletic pubalgia is a syndrome of persistent groin pain due to chronic repetitive trauma or stress involving the pelvic joints and many musculotendinous structures that cross the anterior pelvis. As a result, the differential diagnosis can be complex, but insertional tendinopathies are the most common. This case report describes a novel approach to the treatment of distal rectus abdominis tendinopathies with ultrasound-guided needle tenotomy and platelet-rich plasma (PRP) injection. After injection, the patient returned to pain-free play at his previous level of intensity. This suggests that PRP may be a useful treatment for this diagnosis. Copyright © 2015.

    Magnetic resonance (MR) imaging technique and findings in the setting of athletic pubalgia, including injury at the rectus abdominis/adductor aponeurosis, are becoming widely recognized. A subset of these patients is treated with various pelvic floor repairs, mesh reinforcements, and tendon releases. Most of these patients do well after intervention, but some have persistent or refractory groin pain, and others eventually develop new injuries in the pubic region or elsewhere about the pelvic girdle. This review describes the expected and some unexpected MRI findings in patients with recurrent or persistent groin pain after a "sports hernia" repair. © Thieme Medical Publishers.

    Full Text Available A 43-year old patient presented to the emergency department with stretch, due to impossible deflation of the penile prosthesis, 4 years after successful implant. A CT-scan showed migration of the reservoir to the left rectus abdominis muscle. Refilling of the reservoir was inhibited by muscular compression, causing stretch. Removal and replacement of the reservoir was performed, after which the prosthesis was well-functioning again. Migration of the penile prosthesis reservoir is extremely rare but can cause several complications, such as stretch.

    The purpose of this study was to analyze upper extremity and core muscle activation when performing push-ups with different suspension devices. Young fit male university students (n = 29) performed 3 push-ups each with 4 different suspension systems. Push-up speed was controlled using a metronome and testing order was randomized. Average amplitude of the electromyographic root mean square of Triceps Brachii, Upper Trapezius, Anterior Deltoid, Clavicular Pectoralis, Rectus Abdominis, Rectus Femoris, and Lumbar Erector Spinae was recorded. Electromyographic signals were normalized to the maximum voluntary isometric contraction (MVIC). Electromyographic data were analyzed with repeated-measures analysis of variance with a Bonferroni post hoc. Based upon global arithmetic mean of all muscles analyzed, the suspended push-up with a pulley system provided the greatest activity (37.76% of MVIC; p push-up with a pulley system also provided the greatest triceps brachii, upper trapezius, rectus femoris and erector lumbar spinae muscle activation. In contrast, more stable conditions seem more appropriate for pectoralis major and anterior deltoid muscles. Independent of the type of design, all suspension systems were especially effective training tools for reaching high levels of rectus abdominis activation. Key PointsCompared with standard push-ups on the floor, suspended push-ups increase core muscle activation.A one-anchor system with a pulley is the best option to increase TRICEP, TRAPS, LUMB and FEM muscle activity.More stable conditions such as the standard push-up or a parallel band system provide greater increases in DELT and PEC muscle activation.A suspended push-up is an effective method to achieve high muscle activity levels in the ABS.

    This study was conducted to quantify the normalized amplitudes of the abdominal wall and back extensor musculature during a variety of push-up styles. We also sought to quantify their impact on spinal loading by calculating spinal compression and torque generation in the L4-5 area. Ten university-age participants, nine males and one female, in good to excellent condition, volunteered to participate in this study. All participants were requested to perform a maximum of 12 different push-up exercises, three trials per exercise. Surface electromyographic data (EMG) were collected bilaterally on rectus abdominis, external oblique, internal oblique, latissimus dorsi, and erector spinae muscles, and unilaterally (right side) on pectoralis major, triceps brachii, biceps brachii, and anterior deltoid muscles. Spine kinetics were obtained using an anatomically detailed model of the torso/spine. This study revealed that more dynamic push-ups (i.e., ballistic, with hand movement) required more muscle activation and higher spine load, whereas placing labile balls under the hands only resulted in modest increases in spine load. Right rectus abdominis (RA) activation was significantly higher than left RA activation during the left hand forward push-up and vice versa for the right hand forward push-up (P push-ups (P push-up resulted in the highest spine compression. Skilled participants showed greater synchronicity with peak muscle activation (plyometric type of contractions) during ballistic push-ups. These data will help guide exercise selection for individuals with differing training objectives and injury history.

    Full Text Available The use of Pilates-based exercises for trunk strengthening has been reported in the literature. The objective of this study was to analyze and compare the electrical activity of the rectus abdominis and external oblique muscles during a traditional abdominal exercise program and an exercise program based on the Pilates method using a ball and an elastic band. The sample was composed of 10 healthy women, non-practitioners of Pilates, who performed the traditional abdominal exercise and roll-up with the ball and elastic band. The sign was normalized by the electromyographic peak of the dynamics activity and was adjusted for 2000 samples/s; the filter was set in a frequency band from 20 to 450 Hz. In the comparison between exercises, the external oblique muscle in the concentric phase had a higher recruitment in the roll-up with the ball (P =0.042. In the comparison between muscles in each exercise, the rectus abdominis showed a higher activation in the concentric phase (P = 0.009 and in the eccentric phase (P = 0.05 of the traditional abdominal exercise. Activation percentages ranged from 15% to 22%. The traditional abdominal exercise had the largest activation percentage.

    One hundred and twenty-seven lambs were fed as follows: lambs and dams grazing alfalfa (Gr); the same as Gr but lambs had access to concentrate (Gr + S); ewes grazed and lambs received milk and concentrate until weaning and thereafter concentrate and straw (Rat-Gr); ewes and lambs were stall-fed (Ind). Lambs were slaughtered at 22-24 kg live weight and fat and M. rectus abdominis colour was measured instrumentally and subjectively. The evolution of the instrumental colour and texture of M. longissimus lumborum was also recorded. There were significant differences in the instrumental colour of subcutaneous fat amongst feeding systems, but no differences were observed upon visual appraisal. On average, M. rectus abdominis colour in the four feeding systems was classed as pink. Differences in longissimus thoracis colour at 0 h disappeared at 24h of air exposure and there were no differences in pH or cooking losses. At no time were any differences in instrumental texture found. Copyright © 2011 Elsevier Ltd. All rights reserved.

    The objective of the research was to assess the effect of a 4-week-long training program on selected parameters: electromechanical delay (EMD) and amplitude of electromyographic signal (EMG). Fourteen female students of the University School of Physical Education participated in the study. Torques and surface electromyography were evaluated under static conditions. Surface electrodes were glued to both sides of the rectus abdominis (RA), external oblique (EO), and erector spinae (ES) muscles. The 4-week-long program was aimed at strengthening the abdominal muscles and resulted in increased EMD during maximum torque production by flexors of the trunk, increased amplitudes of the signals of the erector spinae ( p = 0.005), and increased EMG amplitude asymmetry of the lower ( p = 0.013) and upper part ( p = 0.006) of the rectus abdominis muscle. In a training program composed of a large number of repetitions of strength exercises, in which the training person uses their own weight as the load (like in exercises such as curl-ups), the process of recruitment of motor units is similar to that found during fatiguing exercises and plyometric training.

    Trunk musculature in Urodela species varies by habitat. In this study, trunk musculature was examined in five species of adult salamanders representing three different habitats: aquatic species, Amphiuma tridactylum and Necturus maculosus; semi-aquatic species, Cynops pyrrhogaster; terrestrial species, Hynobius nigrescens and Ambystoma tigrinum. More terrestrial species have heavier dorsal and ventral trunk muscles than more aquatic forms. By contrast, the lateral hypaxial musculature was stronger in more aquatic species. The number of layers of lateral hypaxial musculature varied among Urodela species and did not clearly correlate with their habitats. The M. rectus abdominis was separated from the lateral hypaxial musculature in both terrestrial and semi-aquatic species. In aquatic species, M. rectus abdominis was not separated from lateral hypaxial musculature. Lateral hypaxial musculature differed in thickness among species and was relatively thinner in terrestrial species. In more terrestrial species, dorsal muscles may be used for stabilization and ventral flexing against gravity. Ventral muscle may be used in preventing dorsally concave curvature of the trunk by dorsal muscles and by weight. The lengthy trunk supported by limbs needs muscular forces along the ventral contour line in more terrestrial species. And, the locomotion on well-developed limbs seems to lead to a decrease of the lateral hypaxial musculature.

    The purpose of this study was (1) to evaluate the association of trunk muscle density assessed by computed tomography (CT) with age, gender, and BMI and (2) to evaluate the association between trunk muscle CT density and degenerative disc and facet joint disease of the lumbar spine. The study was IRB approved and HIPAA compliant. The study group comprised 100 subjects (mean age 44.4 ± 22.2 years, 51 % male) who underwent CT of the abdomen and pelvis without intravenous contrast. Exclusion criteria included prior abdominal or spine surgery, active malignancy and scoliosis. CTs were reviewed and the attenuation of the rectus abdominis, transverse abdominis, internal and external obliques, psoas, multifidus, longissimus and gluteus maximus were measured bilaterally at consistent levels. Degenerative disc and bilateral facet joint disease were scored using established methods. Univariate analyses were performed using linear regression. Multivariate linear regression was performed to adjust for age, gender and BMI. CT density of each trunk muscle correlated inversely with age (p degenerative disc and facet joint disease in the univariate analyses (p degenerative disc and facet joint disease respectively in the multivariate analysis. Fatty infiltration of trunk musculature increases with age and BMI. Fatty infiltration of the gluteus maximus and transverse abdominis are associated with degenerative disc and facet joint disease, independent of age, gender and BMI.

The study was IRB approved and HIPAA compliant. The study group comprised 100 subjects (mean age 44.4 ± 22.2 years, 51 % male) who underwent CT of the abdomen and pelvis without intravenous contrast. Exclusion criteria included prior abdominal or spine surgery, active malignancy and scoliosis. CTs were reviewed and the attenuation of the rectus abdominis, transverse abdominis, internal and external obliques, psoas, multifidus, longissimus and gluteus maximus were measured bilaterally at consistent levels. Degenerative disc and bilateral facet joint disease were scored using established methods. Univariate analyses were performed using linear regression. Multivariate linear regression was performed to adjust for age, gender and BMI. CT density of each trunk muscle correlated inversely with age (p < 0.001) and BMI (p < 0.001). CT density of each trunk muscle correlated inversely with degenerative disc and facet joint disease in the univariate analyses (p < 0.001); however, only the gluteus maximus and the transverse abdominis remained significant predictors of degenerative disc and facet joint disease respectively in the multivariate analysis. Fatty infiltration of trunk musculature increases with age and BMI. Fatty infiltration of the gluteus maximus and transverse abdominis are associated with degenerative disc and facet joint disease, independent of age, gender and BMI. (orig.)

    The aim of the present study was to measure in vivo skeletal muscle elasticity in the transverse and longitudinal planes using shear wave elastography and then to compare the image stability, measurement values and measurement repeatability between these imaging planes. Thirty-one healthy males participated in this study. Tissue elasticity (shear wave velocity) of the medial gastrocnemius, rectus femoris, biceps brachii and rectus abdominis was measured in both the transverse and longitudinal planes using shear wave elastography. Image stability was evaluated by the standard deviation of the colour distribution in the shear wave elastography image. Measurement repeatability was assessed by the coefficient of variance obtained from three measurement values. Image stability of all tested muscles was significantly higher in the longitudinal plane (Pplanes (P>0·05), except in the biceps brachii (P = 0·001). Measurement values of the medial gastrocnemius, rectus femoris and biceps brachii were significantly different between the imaging planes (Pplane, which indicates that imaging plane should be considered when measuring skeletal muscle tissue elasticity by shear wave elastography. © 2015 Scandinavian Society of Clinical Physiology and Nuclear Medicine.

    Full Text Available BACKGROUND: The transverse abdominal plan blockade is a block of abdominal wall that has diffused rapidly in the clinical practice as part of a multimodal analgesia for abdominal surgery. The performance of the ultrasound-guided technique has allowed the lowering of potential complications, as well as new approaches that were carried out according to the descriptions, and the prospective studies would make it possible to utilize the transverse abdominal plan blockade in different surgical interventions; however, the results obtained in randomized clinical trials are inconsistent.OBJECTIVES: To prepare a systematic review aiming to determine the efficacy of the ultrasound-guided transverse abdominal plan blockade for different surgical interventions, as well as the indications according to the approaches and their influences.METHODS: Two research approaches, one manual, and the other in Pubmed returned 28 randomized clinical trials where intervention with ultrasound-guided transverse abdominal plan blockades was performed to compare the analgesic efficacy in contrast to another technique in adults, published between 2007 and October 2013, in English or Spanish, with Jadad score > 1, according to the inclusion criteria for this review. The authors analyzed independently all the randomized clinical trials.CONCLUSIONS: The transverse abdominal plan blockades have been shown to be an effective technique in colorectal surgery, cesarean section, cholecystectomy, hysterectomy, appendectomy, donor nephrectomy, retropubic prostatectomy, and bariatric surgery. However, the data found in randomized clinical trial are not conclusive, and as a result, it is necessary to develop new and well designed randomized clinical trial, with enough statistical power to compare different approaches, drugs, doses, and volumes for the same intervention, aiming to answer the current questions and their effects in the habitual clinical practice.

Although trunk muscle composition is important to physical function, the implication of ectopic fat in the trunk muscles with respect to physical fitness and its potential for modification by lifestyle changes is unknown. Methods: The effects of a 6-month period of either weight loss (WL alone or of aerobic exercise (AEX plus WL (AEX+WL, on trunk body composition, as measured by dual-energy X-ray absorptiometry (DXA (to measure trunk fat and lean mass and computed tomography (CT (to measure the erector spinae, psoas, lateral abdominal, rectus abdominis muscle, and intramuscular fat, and the intramuscular adipose tissue [IMAT] areas was determined in 65 overweight and obese postmenopausal women (aged 50-76 years. Results: The area of the erector spinae, psoas, and rectus abdominis muscles declined with age in the women (P<0.05. Both the spinal and abdominal muscle areas were related to the maximal oxygen uptake (VO2max (P<0.05. Body weight decreased by 8% after both AEX+WL and WL (P<0.001. The VO2max increased by 11% after AEX+WL (P<0.001 but did not change with WL alone (group effect, P<0.001. The DXA-measured trunk fat mass decreased by 16% after AEX+WL (P<0.001 and by 12% after WL (P<0.001. When both groups were combined, the IMAT decreased in all four muscle groups - by 6% in the erector spinae (P<0.01, by 9% in the psoas (P<0.01, by 11% in the lateral abdominals (P<0.001, and by 6% in the rectus abdominis (P<0.05. The loss of fat mass was related to the loss of IMAT of the erector spinae and the lateral abdominals. Conclusions: A lifestyle

    Full Text Available The cannabinoid type 1 (CB1 receptor is widely distributed in the brain and peripheral organs where it regulates cellular functions and metabolism. In the brain, CB1 is mainly localized on presynaptic axon terminals but is also found on mitochondria (mtCB1, where it regulates cellular respiration and energy production. Likewise, CB1 is localized on muscle mitochondria, but very little is known about it. The aim of this study was to further investigate in detail the distribution and functional role of mtCB1 in three different striated muscles. Immunoelectron microscopy for CB1 was used in skeletal muscles (gastrocnemius and rectus abdominis and myocardium from wild-type and CB1-KO mice. Functional assessments were performed in mitochondria purified from the heart of the mice and the mitochondrial oxygen consumption upon application of different acute delta-9-tetrahidrocannabinol (Δ9-THC concentrations (100 nM or 200 nM was monitored. About 26% of the mitochondrial profiles in gastrocnemius, 22% in the rectus abdominis and 17% in the myocardium expressed CB1. Furthermore, the proportion of mtCB1 versus total CB1 immunoparticles was about 60% in the gastrocnemius, 55% in the rectus abdominis and 78% in the myocardium. Importantly, the CB1 immunolabeling pattern disappeared in muscles of CB1-KO mice. Functionally, acute 100 nM or 200 nM THC treatment specifically decreased mitochondria coupled respiration between 12% and 15% in wild-type isolated mitochondria of myocardial muscles but no significant difference was noticed between THC treated and vehicle in mitochondria isolated from CB1-KO heart. Furthermore, gene expression of key enzymes involved in pyruvate synthesis, tricarboxylic acid (TCA cycle and mitochondrial respiratory chain was evaluated in the striated muscle of CB1-WT and CB1-KO. CB1-KO showed an increase in the gene expression of Eno3, Pkm2, and Pdha1, suggesting an increased production of pyruvate. In contrast, no significant

    To determine whether the immediate postoperative alignment among patients undergoing successful bilateral weakening surgery for esotropia is different in children compared to adults. The medical records of all patients undergoing surgery for esotropia by a single surgeon at a major academic referral center between January 1, 2002, and July 1, 2014 (n = 544), were retrospectively reviewed. Exclusion criteria included those with prior strabismus surgery, unilateral surgery, strengthening procedures, vertical or superior oblique surgery, and those wearing hyperopic spectacles for accommodative esotropia. Additionally, all patients had to have a 1- and 6-week postoperative examination and 8 prism diopters (PD) or less of deviation at their 6-week examination. Ninety-five (17.5%) of the 544 patients met the inclusion criteria. Surgery was performed at a median age of 3.7 years (range: 7 months to 86 years) for a median esodeviation of 35 PD (range: 12 to 70 PD). Among the 73 patients younger than 11 years, the immediate mean postoperative alignment was 9 PD of exotropia (range: 14 PD esotropia to 30 PD exotropia) compared to 2 PD of exotropia (range: 9 PD esotropia to 30 PD exotropia) in the 22 patients 11 years or older (P = .001). Seventy-one percent of successfully aligned patients younger than 11 years were exotropic in the immediate postoperative week compared to 23% of those 11 years or older (P XXXX.].

    Saeterbakken, Atle H; Fimland, Marius S

    2013-01-01

    The purpose of the study was to compare force output and muscle activity of leg and trunk muscles in isometric squats executed on stable surface (i.e., floor), power board, BOSU ball, and balance cone. Fifteen healthy men (23.3 ± 2.7 years, mass: 80.5 ± 8.5 kg, height: 1.81 ± 0.09 m) volunteered. The force output and electromyographic (EMG) activities of the rectus femoris, vastus medialis, vastus lateralis, biceps femoris, soleus, rectus abdominis, oblique external, and erector spinae were assessed. The order of the surfaces was randomized. One familiarization session was executed before the experimental test. Compared with stable surface (749 ± 222 N), the force output using power board was similar (-7%, p = 0.320) but lower for BOSU ball (-19%, p = 0.003) and balance cone (-24%, p ≤ 0.001). The force output using BOSU ball and balance cone was approximately 13% (p = 0.037) and approximately 18% (p = 0.001) less than the power board. There were similar EMG activities between the surfaces in all muscles except for rectus femoris, in which stable squat provided greater EMG activity than did the other exercises (p = 0.004-0.030). Lower EMG activity was observed in the rectus femoris using balance cone compared with the BOSU ball (p = 0.030). In conclusion, increasing the instability of the surface during maximum effort isometric squats usually maintains the muscle activity of lower-limb and superficial trunk muscles although the force output is reduced. This suggests that unstable surfaces in the squat may be beneficial in rehabilitation and as a part of periodized training programs, because similar muscle activity can be achieved with reduced loads.

    The momentum to compose this Leading Opinion on the synergistic induction of bone formation suddenly arose when a simple question was formulated during a discussion session on how to boost the often limited induction of bone formation seen in clinical contexts. Re-examination of morphological and molecular data available on the rapid induction of bone formation by the recombinant human transforming growth factor-β3 (hTGF-β3) shows that hTGF-β3 replicates the synergistic induction of bone formation as invocated by binary applications of hOP-1:hTGF-β1 at 20:1 by weight when implanted in heterotopic sites of the rectus abdominis muscle of the Chacma baboon, Papio ursinus. The rapid induction of bone formation in primates by hTGF-β3 may stem from bursts of cladistic evolution, now redundant in lower animal species but still activated in primates by relatively high doses of hTGF-β3. Contrary to rodents, lagomorphs and canines, the three mammalian TGF-β isoforms induce rapid and substantial bone formation when implanted in heterotopic rectus abdominis muscle sites of P. ursinus, with unprecedented regeneration of full thickness mandibular defects with rapid mineralization and corticalization. Provocatively, thus providing potential molecular and biological rationales for the apparent redundancy of osteogenic molecular signals in primates, binary applications of recombinant human osteogenic protein-1 (hOP-1) with low doses of hTGF-β1 and -β3, synergize to induce massive ossicles in heterotopic rectus abdominis, orthotopic calvarial and mandibular sites of P. ursinus. The synergistic binary application of homologous but molecularly different soluble molecular signals has indicated that per force several secreted molecular signals are required singly, synchronously and synergistically to induce optimal osteogenesis. The morphological hallmark of the synergistic induction of bone formation is the rapid differentiation of large osteoid seams enveloping

    Becker muscular dystrophy (BMD) is a progressive neuromuscular disorder caused by mutations in the dystrophin gene. The sensitivity to non-depolarizing muscle relaxant in a patient with muscle dystrophy is reportedly higher than that in normal individuals, and the duration of the effect is known to be prolonged. In this report, we present the case of a 58-year-old man with BMD who underwent laparoscopic cholecystectomy for symptomatic cholelithiasis under total intravenous anesthesia without the use of muscle-relaxant drugs and supplemented with regional anesthesia. Anesthesia was induced and maintained with propofol, remifentanil, and fentanyl; ultrasound-guided bilateral rectus sheath block (RSB) and right-sided subcostal transversus abdominis plane block (TAP) were performed. The procedure required conversion to open surgery because of hard conglutination; intraoperative and postoperative periods were uneventful. Adequate analgesia was maintained after extubation because of the effect of RSB and TAP.

    [Purpose] We investigated the effects of individual strengthening exercises for the stabilization muscles on the nutation torque of the sacroiliac joint in a sedentary worker with nonspecific sacroiliac joint pain. [Subject] A 36-year-old female complained of pain in the sacroiliac joints. [Methods] The subject performed individual strengthening exercises for the stabilization muscles for nutation torque of the sacroiliac joint for 3 weeks. Pain-provocation tests and visual analog scale (VAS) scores were evaluated before and after the exercises. [Results] After performing the individual strengthening exercises for the erector spinae, rectus abdominis, and biceps femoris muscles for 3 weeks, the subject displayed no pain in the pain provocation tests, and the VAS score was 2/10. [Conclusion] The individual strengthening exercises for the stabilization muscles of the sacroiliac joint performed in the present study appear to be effective for sedentary workers with sacroiliac joint pain.

    Prune Belly Syndrome is a rare congenital anomaly characterized by deficient anterior abdominal wall musculature, bilateral cryptorchidism, bilateral megaureters and often unilateral or bilateral vesico-ureteric junction obstruction. The report of prune belly syndrome in the adult is scanty. We report a case of prune belly syndrome in a 24 year old Nigerian who presented with 3 year history of recurrent right loin pain. Examination showed wrinkled abdominal skin, bilateral undescended testes and an hypoplastic rectus abdominis, below the umbilicus. Further evaluation revealed enlarged bladder, bilateral megaureters and right intra-abdominal testis. A diagnosis of Prune Belly Syndrome was made. The challenges in the diagnosis and management of this rare condition are highlighted in this presentation.

    BACKGROUND: This original study evaluated the electromyograph (EMG) activity of four upper body muscles: triceps brachii, erector spinae, upper rectus abdominis, and pectoralis major, while external chest compressions (ECCs) were performed in simulated Martian hypogravity using a Body Suspension Device, counterweight system, and standard full body cardiopulmonary resuscitation (CPR) mannequin. METHOD: 20 young, healthy male subjects were recruited. One hundred compressions divided into four sets, with roughly six seconds between each set to indicate 'ventilation', were performed within approximately a 1.5 minute protocol. Chest compression rate, depth and number were measured along with the subject's heart rate (HR) and rating of perceived exertion (RPE). RESULTS: All mean values were used in two-tailed t-tests using SPSS to compare +1 Gz values (control) versus simulated hypogravity values. The AHA (2005) compression standards were maintained in hypogravity. RPE and HR increased by 32% (p training regimes in case of a serious cardiac event in hypogravity.

    The lateral abdominal wall is comprised of three muscles, each with a different function and orientation. The transversus abdominus, internal oblique, and external oblique muscles span the abdominal cavity between the iliocostalis lumborum and quadratus lumborum posteriorly and the rectus abdominis anteriorly. The lateral abdominal wall is bound superiorly by the lower ribs and costal cartilages and inferiorly by the iliac crest and inguinal ligament. The lateral abdominal wall may be acutely or chronically injured in a variety of athletic endeavors, with occasional acute injuries in the setting of high-energy trauma such as motor vehicle collisions. Injuries to the lateral abdominal wall may result in lumbar hernia formation, unique for its high incarceration rate, and also Spigelian hernias. This article will review the anatomy, the magnetic resonance (MR) imaging approach, and the features and complications of lateral abdominal wall injuries. (orig.)

    Objectives: To report findings in bone scans for breast cancer patients with mastectomy and breast reconstruction with transverse rectus abdominis myocutaneous flap (TRAM). Material and Methods: Inclusion criteria were: confirmed breast cancer, mastectomy, breast reconstruction with TRAM flap and bone scan performed after TRAM. Exclusion criteria were: Absence of bone scan image, breast reconstruction by other approaches. Results: Absence of uptake in TRAM flap in six patients, diminished uptake in skin near TRAM, with peripheral increased uptake in three and increased uptake in TRAM flap, in a patient with cancer recurrence, confirmed by biopsy. Conclusions: Bone scans in breast cancer patients with mastectomy and TRAM flap can have different imaging presentations, procedure details diminish reporting errors. TRAM flap may present fat necrosis areas, which should be differentiated from recurrence in bone scans. Additional imaging and biopsy will be needed to diagnose this finding. (authors).

    [Purpose] The purpose of this study was to document the effect of individual strengthening exercises for posterior pelvic tilt muscles on back pain, pelvic tilt angle, and lumbar ROM of a low back pain (LBP) patient with excessive lordosis. [Subjects] The subject was a 28 year-old male with excessive lordosis who complained of severe LBP at the L3 level. [Methods] He performed individual strengthening exercises for the posterior pelvic tilt muscles (rectus abdominis, gluteus maximus, hamstring). [Results] Pelvic tilt angles on the right and left sides recovered to his normal ranges. Limited lumbar ROM increased, and low back pain decreased. [Conclusion] We suggest that an approach of individual resistance exercises is necessary for the effective and fast strengthening of the pelvic posterior tilt muscles in case of LBP with excessive lordosis.

    Patients presenting for emergency abdominal procedures often have medical issues that cause both general anaesthesia and central neuraxial blockade to pose significant risks. Regional anaesthetic techniques are often used adjunctively for abdominal procedures under general anaesthesia, but there is limited published data on procedures done under peripheral nerve or plexus blocks. We herein report the case of a patient with recent pulmonary embolism and supraventricular tachycardia who required colostomy refashioning. Ultrasonography-guided regional anaesthesia was administered using a combination of ilioinguinal-iliohypogastric, rectus sheath and transversus abdominis plane blocks. This was supplemented with propofol and dexmedetomidine sedation as well as intermittent fentanyl and ketamine boluses to cover for visceral stimulation. We discuss the anatomical rationale for the choice of blocks and compare the anaesthetic conduct with similar cases that were previously reported.

    In advanced pelvic cancer it may be necessary to perform a total pelvic exenteration. In such cases urinary tract reconstruction is usually achieved with the creation of an ileal conduit with a urinary stoma on the right side of the patient's abdomen and an end colostomy separately on the left. The potential morbidity from a second stoma may be avoided by the use of a double-barrelled wet colostomy (DBWC), as a single stoma. Another advantage is the possibility of using a vertical rectus abdominis muscle flap for perineal reconstruction. All patients undergoing formation of a DBWC were included. A DBWC was formed in 10 patients. One patient underwent formation of a double-barrelled wet ileostomy. In this technical note we present our early experience in 11 cases and a video of DBWC formation in a male patient.

    Objective. To describe the MR findings in athletes with pubalgia.Design and patients. Pelvic MR images of 32 athletes (30 men, 2 women) with pubalgia were studied. T1-weighted and T2-weighted (SE and FSE) and STIR images in the axial and coronal planes were obtained on a 1.5-T system. Images were reviewed for general pelvic pathology. Special attention was given to the pubic symphysis, groin and pelvic musculature, and to the abdominal wall musculature.Results. Thirty surgically confirmed cases comprise the study group. Abnormalities in the following were found: pubic symphysis (21/30), abdominal wall (27/30), groin musculature, including rectus abdominis (21/30), pectineus (6/30), and adductor muscle group (18/30).Conclusions. Pubalgia is a complex process which is frequently multifactorial. The MRI findings can alter the surgical approach. (orig.)

    Athletic pubalgia is a frequently encountered syndrome for clinicians who treat active patients participating in a wide variety of athletic endeavors worldwide. Pathologies associated with this clinical scenario span anatomically from the pubic symphysis to the hip and include a myriad of poorly understood and incompletely described musculoskeletal entities, many of which are centered about the pubic symphysis and its tendinous attachments. In this article, we discuss the relevant anatomy and pathophysiology for the most frequently encountered of these disorders, using magnetic resonance (MR) images as a guide. We describe an MR imaging protocol tailored to clinical athletic pubalgia. We then review reproducible MRI patterns of pathology about the pubic symphysis, the rectus abdominis/adductor aponeurosis and the inguinal ring, as well as a group of clinically confounding entities remote from the symphysis but visible by MRI.

    Magnetic resonance imaging (MRI) has become the standard of care imaging modality for a difficult, often misunderstood spectrum of musculoskeletal injury termed athletic pubalgia or core muscle injury. Armed with a dedicated noncontrast athletic pubalgia protocol and a late model phased array receiver coil, the musculoskeletal imager can play a great role in effective diagnosis and treatment planning for lesions, including osteitis pubis, midline pubic plate lesions, and rectus abdominis/adductor aponeurosis injury. Beyond these established patterns of MRI findings, there are many confounders and contributing pathologies about the pelvis in patients with activity related groin pain, including internal and periarticular derangements of the hip. The MRI is ideally suited to delineate the extent of expected injury and to identify the unexpected visceral and musculoskeletal lesions.

    Full Text Available Surgical treatment for athletic pubalgia is the standard of care, however, it poses risks. This study investigated the use of ultrasound-guided corticosteroid injections as an alternative treatment. Twelve consecutive patients underwent injections into the area of degeneration in the rectus abdominis and/or adductor longus aponeurosis. The Western Ontario and McMaster Universities (WOMAC scores were used to evaluate treatment effectiveness. The average WOMAC score was 90.9. With a mean follow up of 8.7 months (range, 6–19 months, eight of the 12 patients reported complete symptom resolution. In conclusion, corticosteroid injections alleviate pain in patients with athletic pubalgia and provide an alternative to surgery.

    To describe the MR findings in athletes with pubalgia. Pelvic MR images of 32 athletes (30 men, 2 women) with pubalgia were studied. T1-weighted and T2-weighted (SE and FSE) and STIR images in the axial and coronal planes were obtained on a 1.5-T system. Images were reviewed for general pelvic pathology. Special attention was given to the pubic symphysis, groin and pelvic musculature, and to the abdominal wall musculature. Thirty surgically confirmed cases comprise the study group. Abnormalities in the following were found: pubic symphysis (21/30), abdominal wall (27/30), groin musculature, including rectus abdominis (21/30), pectineus (6/30), and adductor muscle group (18/30). Pubalgia is a complex process which is frequently multifactorial. The MRI findings can alter the surgical approach.

    To present the clinical management of inguinal disruption in a professional hockey player and highlight the importance of a multidisciplinary approach to diagnosis and management. A professional hockey player with recurrent groin pain presented to the clinic after an acute exacerbation of pain while playing hockey. The patient received a clinical diagnosis of inguinal disruption. Imaging revealed a tear in the rectus abdominis. Management included two platelet-rich plasma (PRP) injections to the injured tissue, and subsequent manual therapy and exercise. The patient returned to his prior level of performance in 3.5 weeks. This case demonstrated the importance of a multidisciplinary team and the need for advanced imaging in athletes with groin pain. Research quality concerning the non-surgical management of inguinal disruption remains low. This case adds evidence that PRP, with the addition of manual therapy and exercise may serve as a relatively quick and effective non-surgical management strategy.

    Abdominoperineal resection (APR) of anorectal cancers after neoadjuvant chemoradiotherapy may incur significant perineal morbidity. While vertical rectus abdominis muscle (V-RAM) flaps can fill the pelvic resection space with health tissue, their use has previously been described predominantly in association with laparotomy. Here, we describe a means of combination laparoscopic APR with V-RAM flap reconstruction that allows structural preservation of the entire abdominal wall throughout the oncological resection and of the deep parietal layers after V-RAM donation. Furthermore, a single port access device used at the end colostomy site allows a second senior surgeon assist with an additional two working instruments for the purpose of improved pelvic tissue retraction, especially useful in obese patients.

    We managed five patients with large skull base defects complicated by complex infections with microvascular free tissue transfer. The first patient developed an infection, cerebrospinal fluid (CSF) leak, and meningitis after undergoing a translabyrinthine resection of an acoustic neuroma. The second patient had a history of a gunshot wound to the temporal bone, with a large defect and an infected cholesteatoma that caused several episodes of meningitis. The third through the fifth patients had persistent CSF leakage and infection refractory to conventional therapy. In all cases prior attempts of closure with fat grafts or regional flaps had failed. Rectus abdominis myofascial free flap, radial forearm free flap or a gracilis muscle free flap was used after debridement of the infected cavities. The CSF leaks, local infections, and meningitis were controlled within a week. In our experience, microvascular free tissue provides the necessary bulk of viable, well-vascularized tissue, which not only assures a mechanical seal but also helps clear the local infection.

    The lateral abdominal wall is comprised of three muscles, each with a different function and orientation. The transversus abdominus, internal oblique, and external oblique muscles span the abdominal cavity between the iliocostalis lumborum and quadratus lumborum posteriorly and the rectus abdominis anteriorly. The lateral abdominal wall is bound superiorly by the lower ribs and costal cartilages and inferiorly by the iliac crest and inguinal ligament. The lateral abdominal wall may be acutely or chronically injured in a variety of athletic endeavors, with occasional acute injuries in the setting of high-energy trauma such as motor vehicle collisions. Injuries to the lateral abdominal wall may result in lumbar hernia formation, unique for its high incarceration rate, and also Spigelian hernias. This article will review the anatomy, the magnetic resonance (MR) imaging approach, and the features and complications of lateral abdominal wall injuries. (orig.)

    The purpose of this study was to assess the effects of adding elastic bands to free-weight squats on the neuromuscular activation of core muscles. Twenty-five resistance trained women with 4.6 ± 2.1 years of resistance training experience participated in the study. In randomized order, the participants performed 6 repetition maximum in free-weight squats, with and without elastic bands (i.e., matched relative intensity between exercises). During free-weight squats with elastic bands, some of the free weights were replaced with 2 elastic bands attached to the lowest part of the squat rack. Surface electromyography (EMG) activity was measured from the erector spinae, external oblique, and rectus abdominis, whereas a linear encoder measured the vertical displacement. The EMG activities were compared between the 2 lifting modalities for the whole repetition and separately for the eccentric, concentric, and upper and lower eccentric and concentric phases. In the upper (greatest stretch of the elastic band), middle, and lower positions in squats with elastic bands, the resistance values were approximately 117, 105, and 93% of the free weight-only trial. Similar EMG activities were observed for the 2 lifting modalities for the erector spinae (p = 0.112-0.782), external oblique (p = 0.225-0.977), and rectus abdominis (p = 0.315-0.729) in all analyzed phases. In conclusion, there were no effects on the muscle activity of trunk muscles of substituting some resistance from free weights with elastic bands in the free-weight squat.

    Full Text Available Trimethylsulfonium, a compound present in the midgut gland of the sea hare Aplysia brasiliana, negatively modulates vagal response, indicating a probable ability to inhibit cholinergic responses. In the present study, the pharmacological profile of trimethylsulfonium was characterized on muscarinic and nicotinic acetylcholine receptors. In rat jejunum the contractile response induced by trimethylsulfonium (pD2 = 2.46 ± 0.12 and maximal response = 2.14 ± 0.32 g was not antagonized competitively by atropine. The maximal response (Emax to trimethylsulfonium was diminished in the presence of increasing doses of atropine (P<0.05, suggesting that trimethylsulfonium-induced contraction was not related to muscarinic stimulation, but might be caused by acetylcholine release due to presynaptic stimulation. Trimethylsulfonium displaced [³H]-quinuclidinyl benzilate from rat cortex membranes with a low affinity (Ki = 0.5 mM. Furthermore, it caused contraction of frog rectus abdominis muscles (pD2 = 2.70 ± 0.06 and Emax = 4.16 ± 0.9 g, which was competitively antagonized by d-tubocurarine (1, 3 or 10 µM with a pA2 of 5.79, suggesting a positive interaction with nicotinic receptors. In fact, trimethylsulfonium displaced [³H]-nicotine from rat diaphragm muscle membranes with a Ki of 27.1 µM. These results suggest that trimethylsulfonium acts as an agonist on nicotinic receptors, and thus contracts frog skeletal rectus abdominis muscle and rat jejunum smooth muscle via stimulation of postjunctional and neuronal prejunctional nicotinic cholinoreceptors, respectively.

    Full Text Available Abstract Introduction Military police activity individuals performing operational activity remain 12 hours using mandatory safety equipment. This work aimed to verify the electromyographic response in operational military police officers before and after a cycle of two working days. Methods Forty-four male individuals were evaluated, with an average age of 34.59 ± 8.05. The used protocol consisted in the evaluation of paravertebral muscles and rectus abdominis muscles in a maximum isometric voluntary contraction test (MVC during trunk extension movements, starting from the sitting position. Moreover, the Roland-Morris functional evaluation questionnaire and the Corlett and Manenica diagram for painful areas were used. An electromyograph with 16 pre-set channels was used. Signals were processed in time (EMGME and spectral (EMGMF domains, using the MatLab® program. The Shapiro-Wilk test and Wilcoxon Signed Ranks Test were applied. Statistical analyses were performed through the SPSS v21.0 software and Microsoft Office Excel 2010, considering p < 0.05 as significance level. Results Results showed statistical differences in the post-working day for time analysis, an EMGME decrease in the right rectus abdominis muscle (p = 0.016 and in the age-stratified sample, with individuals over 31 years old (p = 0.016; in the spectral analysis, EMGMF reduction in the right iliocostalis (p = 0.027 and right and left side in the stratified sample, in individuals over 31 years old and with more than 10 years of service. Conclusion The used protocol highlighted a decrease in the amplitude of the electromyographic signal, as well as possible muscle fatigue on the right side where officers usually carry their weapons.

    Full Text Available Background Although the utility of flaps for the treatment of sternal wound infections following median sternotomy has been reported for 30 years, there have been few reports on the risk factors for complications after reconstruction. The objective of this investigation was to identify factors related to complications after the reconstruction of sternal wound infections. Methods A retrospective analysis of 74 patients with reconstructive surgery after sternal wound infection over a 5-year period was performed. Clinical data including age, sex, body mass index (BMI, comorbidities, bacterial culture, previous cardiac surgery, wound depth, mortality rate, type of reconstructive procedure, and complication rate were collected. Results The patients' BMI ranged from 15.2 to 33.6 kg/m2 (mean, 23.1±3.74 kg/m2. Wound closure complications after reconstructive surgery were observed in 36.5% of the cases. The mortality rate was 2.7%. Diabetes mellitus significantly affected the rate of wound closure complications (P=0.041. A significant difference in the number of complications was seen between Staphylococcus aureus (S. aureus and coagulase-negative Staphylococci (P=0.011. There was a correlation between harvesting of the internal thoracic artery and postoperative complications (P=0.048. The complication rates of the pectoralis major flap, rectus abdominis flap, omentum flap, a combination of pectoralis major flap and rectus abdominis flap, and direct closure were 23.3%, 33.3%, 100%, 37.5%, and 35.7%, respectively. Conclusions Diabetes mellitus, S. aureus, harvesting of the internal thoracic artery, and omentum flap were significant factors for complications after reconstruction. The omentum flap volume may be related to the complications associated with the omentum flap transfer in the present study.

    Most mammals possess stamina because their locomotor and respiratory (i.e., ventilatory) systems are mechanically coupled. These systems are decoupled, however, in bottlenose dolphins (Tursiops truncatus) as they swim on a breath-hold. Locomotion and ventilation are coupled only during their brief surfacing event, when they respire explosively (up to 90% of total lung volume in approximately 0.3s) (Ridgway et al., 1969). The predominantly slow-twitch fiber profile of their diaphragm (Dearolf, 2003) suggests that this muscle does not likely power their rapid ventilatory event. Based upon Bramble's (1989) biomechanical model of locomotor-respiratory coupling in galloping mammals, it was hypothesized that locomotor muscles function to power ventilation in bottlenose dolphins. It was further hypothesized that these muscles would be composed predominantly of fast-twitch fibers to facilitate the bottlenose dolphin's rapid ventilation. The gross morphology of cranio-cervical (scalenus, sternocephalicus, sternohyoid), thoracic (intercostals, transverse thoracis), and lumbo-pelvic (hypaxialis, rectus abdominis, abdominal obliques) muscles (n=7) and the fiber-type profiles (n=6) of selected muscles (scalenus, sternocephalicus, sternohyoid, rectus abdominis) of bottlenose dolphins were investigated. Physical manipulations of excised thoracic units were carried out to investigate potential actions of these muscles. Results suggest that the cranio-cervical muscles act to draw the sternum and associated ribs cranio-dorsally, which flares the ribs laterally, and increases the thoracic cavity volume required for inspiration. The lumbo-pelvic muscles act to draw the sternum and caudal ribs caudally, which decreases the volumes of the thoracic and abdominal cavities required for expiration. All muscles investigated were composed predominantly of fast-twitch fibers (range 61-88% by area) and appear histochemically poised for rapid contraction. These combined results suggest that

    The goal of this study was to present a procedure that would enable mathematical analysis of the increase of linear sizes of human anatomical structures, estimate mathematical model parameters and evaluate their adequacy. Section material consisted of 67 foetuses-rectus abdominis muscle and 75 foetuses- biceps femoris muscle. The following methods were incorporated to the study: preparation and anthropologic methods, image digital acquisition, Image J computer system measurements and statistical analysis method. We used an anthropologic method based on age determination with the use of crown-rump length-CRL (V-TUB) by Scammon and Calkins. The choice of mathematical function should be based on a real course of the curve presenting growth of anatomical structure linear size Ύ in subsequent weeks t of pregnancy. Size changes can be described with a segmental-linear model or one-function model with accuracy adequate enough for clinical purposes. The interdependence of size-age is described with many functions. However, the following functions are most often considered: linear, polynomial, spline, logarithmic, power, exponential, power-exponential, log-logistic I and II, Gompertz's I and II and von Bertalanffy's function. With the use of the procedures described above, mathematical models parameters were assessed for V-PL (the total length of body) and CRL body length increases, rectus abdominis total length h, its segments hI, hII, hIII, hIV, as well as biceps femoris length and width of long head (LHL and LHW) and of short head (SHL and SHW). The best adjustments to measurement results were observed in the exponential and Gompertz's models.

  4. Is abdominal wall contraction important for normal voiding in the female rat?

    2007-03-01

    Full Text Available Abstract Background Normal voiding behavior in urethane-anesthetized rats includes contraction of the abdominal wall striated muscle, similar to the visceromotor response (VMR to noxious bladder distension. Normal rat voiding requires pulsatile release of urine from a pressurized bladder. The abdominal wall contraction accompanying urine flow may provide a necessary pressure increment for normal efficient pulsatile voiding. This study aimed to evaluate the occurrence and necessity of the voiding-associated abdominal wall activity in urethane-anesthetized female rats Methods A free-voiding model was designed to allow assessment of abdominal wall activity during voiding resulting from physiologic bladder filling, in the absence of bladder or urethral instrumentation. Physiologic diuresis was promoted by rapid intravascular hydration. Intercontraction interval (ICI, voided volumes and EMG activity of the rectus abdominis were quantified. The contribution of abdominal wall contraction to voiding was eliminated in a second group of rats by injecting botulinum-A (BTX, 5 U into each rectus abdominis to induce local paralysis. Uroflow parameters were compared between intact free-voiding and BTX-prepared animals. Results Abdominal wall response is present in free voiding. BTX preparation eliminated the voiding-associated EMG activity. Average per-void volume decreased from 1.8 ml to 1.1 ml (p Conclusion The voiding-associated abdominal wall response is a necessary component of normal voiding in urethane anesthetized female rats. As the proximal urethra may be the origin of the afferent signaling which results in the abdominal wall response, the importance of the bladder pressure increment due to this response may be in maintaining a normal duration intermittent pulsatile high frequency oscillatory (IPHFO/flow phase and thus efficient voiding. We propose the term Voiding-associated Abdominal Response (VAR for the physiologic voiding-associated EMG

    The present study used synchronized motion analysis to investigate the activity of hip and trunk muscles during deep-water running (DWR) relative to land walking (LW) and water walking (WW). Nine healthy men performed each exercise at self-determined slow, moderate, and fast paces, and surface electromyography was used to investigate activity of the adductor longus, gluteus maxima, gluteus medius, rectus abdominis, oblique externus abdominis, and erector spinae. The following kinematic parameters were calculated: the duration of one cycle, range of motion (ROM) of the hip joint, and absolute angles of the pelvis and trunk with respect to the vertical axis in the sagittal plane. The percentages of maximal voluntary contraction (%MVC) of each muscle were higher during DWR than during LW and WW. The %MVC of the erector spinae during WW increased concomitant with the pace increment. The hip joint ROMs were larger in DWR than in LW and WW. Forward inclinations of the trunk were apparent for DWR and fast-paced WW. The pelvis was inclined forward in DWR and WW. In conclusion, the higher-level activities during DWR are affected by greater hip joint motion and body inclinations with an unstable floating situation.

    This study aimed to examine the effects of kinesiology taping (KT) and different TRX suspension workouts on the amplitude of electromyographic (EMG) activity in the core muscles among people with chronic low back pain (LBP). Each participant (total n = 21) was exposed to two KT conditions: no taping and taping, while performing four TRX suspension exercises: (1) hamstring curl, (2) hip abduction in plank, (3) chest press, and (4) 45-degree row. Right transversus abdominis/internal oblique (TrAIO), rectus abdominis (RA), external oblique (EO), and superficial lumbar multifidus (LMF) activity was recorded with surface EMG and expressed as a percentage of the EMG amplitude recorded during a maximal voluntary isometric contraction of the respective muscles. Hip abduction in plank increased TrAIO, RA, and LMF EMG amplitude compared with other TRX positions (P hamstring curl was effective in inducing a high EMG amplitude of LMF (P 0.05). Hip abduction in plank most effectively activated abdominal muscles, whereas the hamstring curl most effectively activated the paraspinal muscles. Applying KT conferred no immediate benefits in improving the core muscle activation during TRX training in adults with chronic LBP.

    The question that was asked in the study was whether a training routine based on curl-up exercises with a load provided by body mass of the person increases local muscle strength or local muscle endurance. The aim of this study was to evaluate the effect of 4 weeks training based on a small load and low movement velocity on electrical activity (EMG), cross-sectional area (CSA) of core stabilisers. The EMG activity was measured in the rectus abdominis (RA), obliquus abdominis externus and erector spinae (ES) muscles. CSA of the muscles: RA, anterolateral abdominal, psoas major, quadratus lumborum, ES, and multifidus at the level of L3-L4 were measured too. The training increased the CSA and thickness in most of the muscles studied. Statistically significant correlation was found only for the ES circumference (left side) and EMG activity for the right side (r= 0.627, p= 0.022) and left side (r= 0.624, p= 0.023). The training programme resulted in a increase in the number of curl-up repetitions revealing an endurance increase in abdominal muscles. Furthermore, there was a increase in the EMG activity of the RA. An increase of the CSA of all tested muscles showed an increase of muscle active force.

    Abdominal wall muscles have a unique morphology suggesting a complex role in generating and transferring force to the spinal column. Studying passive mechanical properties of these muscles may provide insights into their ability to transfer force among structures. Biopsies from rectus abdominis (RA), external oblique (EO), internal oblique (IO), and transverse abdominis (TrA) were harvested from male Sprague-Dawley rats, and single muscle fibers and fiber bundles (4-8 fibers ensheathed in their connective tissue matrix) were isolated and mechanically stretched in a passive state. Slack sarcomere lengths were measured and elastic moduli were calculated from stress-strain data. Titin molecular mass was also measured from single muscle fibers. No significant differences were found among the four abdominal wall muscles in terms of slack sarcomere length or elastic modulus. Interestingly, across all four muscles, slack sarcomere lengths were quite long in individual muscle fibers (>2.4 µm), and demonstrated a significantly longer slack length in comparison to fiber bundles (p resistance to lengthening at long muscle lengths. Titin molecular mass was significantly less in TrA compared to each of the other three muscles (p < 0.0009), but this difference did not correspond to hypothesized differences in stiffness.

    Vojta reflex locomotion is important to main upright posture through stimulation of breast zone to patient with cerebral palsy. However, application in other diseases is no investigated. So, we determined the effects of stimulation of the breast zone on trunk stability in healthy individuals. Fourteen young healthy adults (7 males and 7 females) voluntarily participated in this study. The subjects were randomly divided into an experimental group (breast zone) and control group (arbitrary point). All groups were stimulated for 5 min on the left and right sides, respectively, for a total 10 times. We used the thickness of the external oblique abdominal muscle (EO), the internal oblique abdominal muscle, the transversus abdominis muscle (TrA), and the rectus abdominis muscles, as well as the area of the diaphragm by using ultrasonography. In the experimental group, the thickness of the TrA significantly increased during stimulation ( P <0.05) while the thickness of the EO significantly decreased ( P <0.05). Also, the area of diaphragm in inspiration was significantly different ( P <0.05). Therefore, stimulation of the breast zone may be effective to improve trunk stability through activation of the TrA muscle and the diaphragm.

    Full Text Available OBJECTIVE: To contrast the efficacy of two exercise programs, segmental stabilization and strengthening of abdominal and trunk muscles, on pain, functional disability, and activation of the transversus abdominis muscle (TrA, in individuals with chronic low back pain. DESIGN: Our sample consisted of 30 individuals, randomly assigned to one of two treatment groups: segmental stabilization, where exercises focused on the TrA and lumbar multifidus muscles, and superficial strengthening, where exercises focused on the rectus abdominis, abdominus obliquus internus, abdominus obliquus externus, and erector spinae. Groups were examined to discovere whether the exercises created contrasts regarding pain (visual analogical scale and McGill pain questionnaire, functional disability (Oswestry disability questionnaire, and TrA muscle activation capacity (Pressure Biofeedback Unit = PBU. The program lasted 6 weeks, and 30-minute sessions occurred twice a week. Analysis of variance was used for inter- and intra-group comparisons. The significance level was established at 5%. RESULTS: As compared to baseline, both treatments were effective in relieving pain and improving disability (p<0.001. Those in the segmental stabilization group had significant gains for all variables when compared to the ST group (p<0.001, including TrA activation, where relative gains were 48.3% and -5.1%, respectively. CONCLUSION: Both techniques lessened pain and reduced disability. Segmental stabilization is superior to superficial strengthening for all variables. Superficial strengthening does not improve TrA activation capacity.

    Body composition of the area at the level of the 4th lumbar vertebral section was studied on X-ray CT images in 62 normal volunteers (32 men and 30 women ), whose ages ranged from 20 and 79 years. The total cross-sectional area was smallest in persons in their twenties, irrespecstive of sex, and began to increase after the age of 30. The abdominal cavity and muscles had the highest cross-sectional ratio (34%) to the total body, followed by subcutaneous fat in men. In women, the subcutaneous fat and abdominal cavity had a ratio of 34% to the total body. According to age groups, men in their twenties and thirties had the highest ratio of the muscle to the total body, followed by that of abdominal cavity and subcutaneous fat. In the group older than 40, the ratio of organs to the total body was as follows: the abdominal cavity>muscle>subcutaneous fat. Since the age of 70, each ratio of the muscle or subcutaneous fat to the total body was the same. Women between their twenties and fifties had the highest ratio of subcutaneous fat to the total body. Since the age of 60, the ratio of the abdominal cavity became highest. The subcutaneous fat and abdominal cavity tended to increase with aging; and the muscles tended to decrease. The real area of the vertebra increased slightly, but the vertebral foramen tended to decrease with aging. In men, mean areas of the muscles were as follows: abdominis lateralis>erector spinae>psoas major>quadratus lumborum and transversospinalis>rectus abdominis muscle. The same tendency was observed for women, except for the quadratus lumborum and rectus abdominis muscle. According to Rohrer index, the real areas of all components except the vertebral foramen tended to increase in the order of types A, C, and D in men. In women, the real area of the subcutaneous fat increased as well in the order of types A, C, and D. (Namekawa, K)

    We investigated the effects of synchronizing kick frequency with the beat of a metronome on kinematic and electromyographic (EMG) parameters during the underwater dolphin kick as a pilot study related to the research that entitled " Effect of increased kick frequency on propelling efficiency and muscular co-activation during underwater dolphin kick" (Yamakawa et al., 2017) [1]. Seven collegiate female swimmers participated in this experiment. The participants conducted two underwater dolphin kick trials: swimming freely at maximum effort, and swimming while synchronizing the kick frequency of maximum effort with the beat of a metronome. The kinematic parameters during the underwater dolphin kick were calculated by 2-D motion analysis, and surface electromyographic measurements were taken from six muscles (rectus abdominis, erector spinae, rectus femoris, biceps femoris, tibialis anterior, and gastrocnemius). The results revealed no significant differences in the kinematic and EMG parameters between trials of the two swimming techniques. Therefore, the action of synchronizing the kick frequency with the beat of a metronome did not affect movement or muscle activity during the underwater dolphin kick in this experiment.

    Ischiatic pressure sores are frequent in spinal cord injury patients, associated with bad prognosis and high recurrence rate. Many surgical techniques were described, including surgical debridement followed by pedicled flap coverage. We aim to propose a practical decision tree for primary or secondary ischial pressure sore treatment. Our series of 48 operated ischial sores with an average follow up of 4 years (range 2 to 8years) is analyzed and compared to previously published reports. Surgical techniques are discussed according to their specific indications. The optimal recurrence rate in published reports about pressure sore treatment is 20%; a rate inferior to 19% is found in our series, showing the equal importance of flap selection and postoperative care and education. Depending on each situation, various available flaps are described and compared: gluteus maximus flap, biceps femoris flap, gracilis flap, tensor fascia lata flap, fasciocutaneous thigh flaps, rectus femoris and vastus lateralis flap, rectus abdominis flap. Specific surgical indications for more extensive wounds are studied: resection arthroplasty of the hip, hip disarticulation, fillet flaps from the leg, microsurgery. Based upon our experience, a decision tree summarizes our proposition of flap selection, depending on the wound size and the patient background. Copyright © 2010 Elsevier Masson SAS.

    Groin pain is a common entity in athletes involved in sports that require acute cutting, pivoting, or kicking such as soccer and ice hockey. Athletic pubalgia is increasingly recognized as a common cause of chronic groin and adductor pain in athletes. It is considered an overuse injury predisposing to disruption of the rectus tendon insertion to the pubis and weakness of the posterior inguinal wall without a clinically detectable hernia. These patients often require surgical therapy after failure of nonoperative measures. A variety of surgical options have been used, and most patients improve and return to high-level competition. PubMed databases were searched to identify relevant scientific and review articles from January 1920 to January 2015 using the search terms groin pain, sports hernia, athletic pubalgia, adductor strain, osteitis pubis, stress fractures, femoroacetabular impingement, and labral tears. Clinical review. Level 4. Athletic pubalgia is an overuse injury involving a weakness in the rectus abdominis insertion or posterior inguinal wall of the lower abdomen caused by acute or repetitive injury of the structure. A variety of surgical options have been reported with successful outcomes, with high rates of return to the sport in the majority of cases. © 2016 The Author(s).

    Abdominal wall endometriosis (AWE) is defined as endometrial tissue that is superficial to the peritoneum. AWE is often difficult to diagnose, mimicking a broad spectrum of diseases. The aim of this study was to describe the appearance of AWE on magnetic resonance (MR) imaging. We present ten patients with AWE (12 lesions) in which MR imaging was used for diagnosis. MR imaging included T2-weighted imaging and T1-weighted imaging with fat suppression. To assess the value of diffusion-weighted imaging (DWI) in endometriosis, four patients underwent additional DWI. The apparent diffusion coefficient (ADC) was calculated using b values of 50, 400, 800 and 1,200 s/mm 2 . In most cases, the lesion was located ventral or dorsal to the aponeurosis of the rectus oblique muscle (n=6) or in the rectus abdominis (n = 5). MR of AWE lesions showed isointense or slightly hyperintense signal compared with muscle on T2-weighted images and showed isointense or slightly hyperintense signal compared with muscle on T1-weighted images with foci of high signal intensity, indicative of haemorrhage. The mean ADC value of AWE was 0.93 x 10 -3 /mm 2 /s. MR imaging seems to be useful in determining the location and depth of infiltration in surrounding tissue preoperatively. (orig.)

    Management of the abdominal compartment syndrome during severe acute pancreatitis by the open abdomen method is associated with considerable morbidity and resource utilization. Thus, the aim of this study was to evaluate the safety and efficacy of the ultrasound-guided percutaneous interventions and/or minimally invasive surgery in the treatment of abdominal compartment syndrome. Forty-four patients with severe acute pancreatitis were enrolled into a prospective study and treated according to the standard management protocol. Interventional and/or surgical management of abdominal compartment syndrome was employed in 6 (13.6%) cases. In the context of this study, we assessed the feasibility and effectiveness of subcutaneous fasciotomy of the anterior m. rectus abdominis sheath, as well as the role of ultrasound-guided drainage of intra-abdominal and peripancreatic fluid collections in the management of abdominal compartment syndrome. Subcutaneous fasciotomy of the anterior m. rectus sheath and ultrasound-guided drainage of intra-abdominal and peripancreatic fluid collections seem to be safe (minor risk of bleeding or infection, closed abdomen, and easy care for the patient) and effective (resulted in a sustained decrease of intra-abdominal pressure to 13-16 mm Hg and regression of organ failures after intervention). Subcutaneous anterior m. rectus fasciotomy may appear to be beneficial in case of refractory abdominal compartment syndrome avoiding morbidity associated with the open abdomen technique. Both the subcutaneous fasciotomy and ultrasound-guided drainage of intra-abdominal and/or peripancreatic fluid collections seem to be safe and effective alternatives in the management of abdominal compartment syndrome; however, prospective studies are needed to further evaluate their clinical role.

    Conclusion: Prolonged sitting led to increased body discomfort in the neck, shoulder, upper back, low back, and buttock. No sign of trunk muscle fatigue was detected over 1 hour of sitting in the upright and forward leaning postures. Prolonged slumped sitting may relate to IO/TrA muscle fatigue, which may compromise the stability of the spine, making it susceptible to injury.

    Full Text Available BACKGROUND: Dermatologic surgeons routinely harvest pedicled flaps at distance with an axial or random pattern to repair facial defects. These types of skin flaps are time-consuming and have high economic, social and personal costs. These drawbacks could be avoided with the introduction of a single-step transfer of free flaps to the recipient site, with microvascular anastomosis. OBJECTIVE: To demonstrate that better results are obtained with myocutaneous or fasciocutaneous free flaps and which one is more suitable in surgical dermatology. MATERIAL AND METHODS: We selected two patients of opposite sexes and similar ages who had undergone Mohs surgery to remove recurrent malignant tumors that were located in the upper cheek bordering the zygomatic zone. The woman was treated with a fasciocutaneous radial free flap and the man with a rectus abdominis free flap. RESULTS: Both patients had excellent immediate postoperative outcomes. Complications observed in the male patient were related to a previous pulmonary alteration. The fasciocutaneous radial free flap reconstruction was easier to perform than the rectus abdominis free flap; nevertheless, the radial free flap is very thin and, although the palmaris longus tendon is used, it does not yield enough volume, requiring later use of implants. In contrast, the rectus abdominis free flap transfers a wide flap with enough fat tissue to expand in the future. As for the cosmetic results regarding the donor site, the rectus abdominis free flap produces better-looking scars, since secondary defects of the palmar surface cannot be directly closed and usually require grafting - a situation that some patients do not accept. CONCLUSIONS: In surgical dermatology, each case, once the tumor has been extirpated, requires its own reconstructive technique. The radial free flap is suitable for thin patients who are willing to cover their arm with a shirt. The rectus abdominis free flap is best suited for obese

METHOD: The distance was measured from the inferior edge of the coracoid process to the point of penetration of the nearest branch of the cutaneous nerve muscle of the coracobrachialis muscle, called base. Starting at the inferior-medial edge of the coracoid process, a second measurement was made to the point at which the lateral fascicle of the brachial plexus crosses the subclavius muscle, denominated height. The third measurement was of the triangular area formed by the two first measurements, denominated area. RESULTS: The average base length was 3.42 cm, varying from 2.38 cm to 4.40 cm. The height measurement was 2.74 cm, on average, varying between 1.03 cm and 3.80 cm. And the average area was 4.92 cm², varying between 1.22 cm² and 7.99 cm². CONCLUSION: These measurements are very important due to the risk of injury in the cutaneous nerve muscle in surgeries performed on the shoulder.

    The aim of this study was to assess the effect of verbal instruction, surface stability, and load intensity on trunk muscle activity levels during the free weight squat exercise. Twelve trained males performed a free weight squat under four conditions: (1) standing on stable ground lifting 50% of their 1-repetition maximum (RM), (2) standing on a BOSU balance trainer lifting 50% of their 1-RM, (3) standing on stable ground lifting 75% of their 1-RM, and (4) receiving verbal instructions to activate the trunk muscles followed by lifting 50% of their 1-RM. Surface EMG activity from muscles rectus abdominis (RA), external oblique (EO), transversus abdominis/internal oblique (TA/IO), and erector spinae (ES) were recorded for each condition and normalized for comparisons. Muscles RA, EO, and TA/IO displayed greater peak activity (39-167%) during squats with instructions compared to the other squat conditions (P=0.04-0.007). Peak EMG activity of muscle ES was greater for the 75% 1-RM condition than squats with instructions or lifting 50% of 1-RM (P=0.04-0.02). The results indicate that if the goal is to enhance EMG activity of the abdominal muscles during a multi-joint squat exercise then verbal instructions may be more effective than increasing load intensity or lifting on an unstable surface. However, in light of other research, conscious co-activation of the trunk muscles during the squat exercise may lead to spinal instability and hazardous compression forces in the lumbar spine.

  7. Trunk Muscle Activation at the Initiation and Braking of Bilateral Shoulder Flexion Movements of Different Amplitudes.

    Directory of Open Access Journals (Sweden)

    M Eriksson Crommert

    Full Text Available The aim of this study was to investigate if trunk muscle activation patterns during rapid bilateral shoulder flexions are affected by movement amplitude. Eleven healthy males performed shoulder flexion movements starting from a position with arms along sides (0° to either 45°, 90° or 180°. EMG was measured bilaterally from transversus abdominis (TrA, obliquus internus (OI with intra-muscular electrodes, and from rectus abdominis (RA, erector spinae (ES and deltoideus with surface electrodes. 3D kinematics was recorded and inverse dynamics was used to calculate the reactive linear forces and torque about the shoulders and the linear and angular impulses. The sequencing of trunk muscle onsets at the initiation of arm movements was the same across movement amplitudes with ES as the first muscle activated, followed by TrA, RA and OI. All arm movements induced a flexion angular impulse about the shoulders during acceleration that was reversed during deceleration. Increased movement amplitude led to shortened onset latencies of the abdominal muscles and increased level of activation in TrA and ES. The activation magnitude of TrA was similar in acceleration and deceleration where the other muscles were specific to acceleration or deceleration. The findings show that arm movements need to be standardized when used as a method to evaluate trunk muscle activation patterns and that inclusion of the deceleration of the arms in the analysis allow the study of the relationship between trunk muscle activation and direction of perturbing torque during one and the same arm movement.

    The purpose of this study was to describe ultrasound (US) changes in muscle thickness produced during automatic activation of the transversus abdominis (TrAb), internal oblique (IO), external oblique (EO), and rectus abdominis (RA), as well as the cross-sectional area (CSA) of the lumbar multifidus (LM), after 1 year of Pilates practice. A 1-year follow-up case series study with a convenience sample of 17 participants was performed. Indeed, TrAb, IO, EO, and RA thickness, as well as LM CSA changes during automatic tests were measured by US scanning before and after 1 year of Pilates practice twice per week. Furthermore, quality of life changes using the 36-Item Short Form Health Survey and US measurement comparisons of participants who practiced exercises other than Pilates were described. Statistically significant changes were observed for the RA muscle thickness reduction during the active straight leg raise test (P = .007). Participants who practiced other exercises presented a larger LM CSA and IO thickness, which was statistically significant (P .05). A direct moderate correlation was observed (r = 0.562, P = .019) between the TrAb thickness before and after a 1-year follow-up. Long-term Pilates practice may reduce the RA thickness automatic activation during active straight leg raise. Furthermore, LM CSA and IO thickness increases were observed in participants who practice other exercise types in conjunction with Pilates. Despite a moderate positive correlation observed for TrAb thickness, the quality of life did not seem to be modified after long-term Pilates practice. Copyright © 2018. Published by Elsevier Inc.

    The information of abdominal wall is very important for the planning of surgical operation and abdominal organ recognition. In research fields of computer assisted radiology and surgery and computer-aided diagnosis, the segmentation and recognition of the abdominal wall muscles in CT images is a necessary pre-processing step. Due to the complexity of the abdominal wall structure and indistinctive in CT images, the automated segmentation of abdominal wall muscles is a difficult issue and has not been solved completely. We propose an approach to segment the abdominal wall muscles and divide it into three categories (front abdominal muscles including rectus abdominis; left and right side abdominal muscles including external oblique, internal oblique and transversus abdominis muscles) automatically. The approach, first, makes an initial classification of bone, fat, and muscles and organs based on the CT number. Then a layer structure is generated to describe the 3-D anatomical structures of human torso by stretching the torso region onto a thin-plate for easy recognition. The abdominal wall muscles are recognized on the layer structures using the spatial relations to the skeletal structure and CT numbers. Finally, the recognized regions are mapped back to the 3-D CT images using an inverse transformation of the stretching process. This method is applied to 20 cases of torso CT images and evaluations are based on visual comparison of the recognition results and the original CT images by an expert in anatomy. The results show that our approach can segment and recognize abdominal wall muscle regions effectively. (orig.)

    Experimental laboratory study. To measure the activation patterns (onset and magnitude) of the abdominal muscles during a standing long jump using wire and surface electromyography. Activation patterns of the abdominal muscles, especially the deep muscles such as the transversus abdominis (TrA), have yet to be examined during full-body movements such as jumping. Thirteen healthy men participated. Wire electrodes were inserted into the TrA with the guidance of ultrasonography, and surface electrodes were attached to the skin overlying the rectus abdominis (RA) and external oblique (EO). Electromyographic signals and video images were recorded while each subject performed a standing long jump. The jump task was divided into 3 phases: preparation, push-off, and float. For each muscle, activation onset relative to the onset of the RA and normalized muscle activation levels (percent maximum voluntary contraction) were analyzed during each phase. Comparisons between muscles and phases were assessed using 2-way analyses of variance. The onset times of the TrA and EO relative to the onset of the RA were -0.13 ? 0.17 seconds and -0.02 ? 0.07 seconds, respectively. Onset of TrA activation was earlier than that of the EO. The activation levels of all 3 muscles were significantly greater during the push-off phase than during the preparation and float phases. Consistent with previously published trunk-perturbation studies in healthy persons, the TrA was activated prior to the RA and EO. Additionally, the highest muscle activation levels were observed during the push-off phase.

  11. Mechanics of lung ventilation in a large aquatic salamander, siren lacertina

    1998-06-01

    Lung ventilation in Siren lacertina was studied using X-ray video, measurements of body cavity pressure and electromyography of hypaxial muscles. S. lacertina utilizes a two-stroke buccal pump in which mixing of expired and inspired gas is minimized by partial expansion of the buccal cavity during exhalation and then full expansion after exhalation is complete. Mixing is further reduced by the use of one or two accessory inspirations after the first, mixed-gas cycle. Exhalation occurs in two phases: a passive phase in which hydrostatic pressure and possibly lung elasticity force air out of the lungs, and an active phase in which contraction of the transverse abdominis (TA) muscle increases body cavity pressure and forces most of the remaining air out. In electromyograms of the lateral hypaxial musculature, the TA became active 200-400 ms before the rise in body cavity pressure, and activity ceased at peak pressure. The TA was not active during inspiration, and no consistent activity during breathing was noted in the external oblique, internal oblique and rectus abdominis muscles. The finding that the TA is the primary expiratory muscle in S. lacertina agrees with findings in a previous study of another salamander, Necturus maculosus. Together, these results indicate that the use of the TA for exhalation is a primitive character for salamanders and support the hypothesis that the breathing mechanism of salamanders represents an intermediate step in evolution between a buccal pump, in which only head muscles are used for ventilation, and an aspiration pump, in which axial muscles are used for both exhalation and inhalation.

    To describe in dogs, a technique for single port access gastropexy and ovariectomy (SPAGO) using a commercially available multitrocar port and to evaluate short-term outcome. Retrospective case series. Dogs (n = 18). A commercially available multitrocar port was inserted into the abdomen lateral to the rectus abdominis muscle and 2-5 cm caudal to the right rib. Dogs were tilted 45° in both left and right recumbency and bilateral ovariectomy performed using articulating graspers, a bipolar vessel sealing device and a 30° telescope. The laparoscopic assisted incisional gastropexy was performed after ovariectomy at the multitrocar port insertion site by grasping the antral portion of the stomach with a 10 mm DuVall forceps and suturing the seromuscular layer of the antral region of the stomach to the transversus abdominis muscle. Eighteen dogs (median weight, 34.5 kg; range, 14.7-59.2 kg) met the inclusion criteria. Median surgical time for SPAGO was 65 minutes (range, 50-225 minutes). Intra-operative complications included, incorrect multitrocar port placement location (n = 3) and mild hemorrhage from a splenic laceration (1) All dogs recovered from surgery and were discharged from the hospital. Single port access gastropexy and ovariectomy is a feasible procedure to provide prophylaxis against gastric dilation-volvulus and a simultaneous means of sterilization in female dogs. Careful and accurate initial multitrocar port insertion is necessary to have optimal operative viewing as well as to reduce the chances of inadvertent splenic laceration. © Copyright 2013 by The American College of Veterinary Surgeons.

    The purpose of the study was to compare 6-repetition maximum (6RM) loads and muscle activity in bench press on 3 surfaces, namely, stable bench, balance cushion, and Swiss ball. Sixteen healthy, resistance-trained men (age 22.5 ± 2.0 years, stature 1.82 ± 6.6 m, and body mass 82.0 ± 7.8 kg) volunteered for 3 habituation/strength testing sessions and 1 experimental session. In randomized order on the 3 surfaces, 6RM strength and electromyographic activity of pectoralis major, deltoid anterior, biceps brachii, triceps brachii, rectus abdominis, oblique external and erector spinae were assessed. Relative to stable bench, the 6RM strength was approximately 93% for balance cushion (p ≤ 0.001) and approximately 92% for Swiss ball (p = 0.008); the pectoralis major electromyographic (EMG) activity was approximately 90% using the balance cushion (p = 0.080) and approximately 81% using Swiss ball (p = 0.006); the triceps EMG was approximately 79% using the balance cushion (p = 0.028) and approximately 69% using the Swiss ball (p = 0.002). Relative to balance cushion, the EMG activity in pectoralis, triceps, and erector spinae using Swiss ball was approximately 89% (p = 0.016), approximately 88% (p = 0.014) and approximately 80% (p = 0.020), respectively. In rectus abdominis, the EMG activity relative to Swiss ball was approximately 69% using stable bench (p = 0.042) and approximately 65% using the balance cushion (p = 0.046). Similar EMG activities between stable and unstable surfaces were observed for deltoid anterior, biceps brachii, and oblique external. In conclusion, stable bench press had greater 6RM strength and triceps and pectoralis EMG activity compared with the unstable surfaces. These findings have implications for athletic training and rehabilitation, because they demonstrate an inferior effect of unstable surfaces on muscle activation of prime movers and strength in bench press. If an unstable surface in bench press is desirable, a balance cushion should

    Patients with Duchenne muscular dystrophy gradually lose the ability to use different muscles of their body. Consequently, they lose the ability to stabilize their trunk against gravity. This hinders them to effectively perform different daily activities. In this paper, we describe the design, realization and evaluation of a trunk orthosis for these patients that should allow them to move their trunk and maintain stability. This study aimed to primarily assess the effectiveness of the trunk support system in terms of unloading of trunk muscles, so only healthy participants were recruited for this phase of the study. Measurements were done on 10 healthy participants (23.4±2.07 [M±SD] years old, average body weight 68.42±24.22 [M±SD] kg). The experiment comprised maintaining a constant trunk posture in three different device conditions (control without orthosis and two conditions with different configurations of the orthosis), at four different flexion angles (10°, 20°, 30°, 40°) for each device condition and for two load conditions (with and without stretching the arms). Electromyography (EMG) signals from the trunk muscles were measured to estimate activation levels of the trunk muscles (iliocostalis, longissimus, external oblique and rectus abdominis) and a motion capture system was used to record the movement of the participants during the experiment. Wearing the orthosis caused reductions in longissimus and iliocostalis activity. The average muscle activity level was 5%-10% of maximum voluntary contraction in the unsupported conditions for those particular muscles. This level was reduced to 3%-9% of maximal voluntary contraction for the supported conditions. No effect on external oblique and rectus abdominis activity was observed. Moreover, no pain or discomfort was reported by any of the participants during the experiment. The results from the current experiment also suggests the necessity of lumber stabilizing systems while using trunk orthosis. The

    The back squat is a traditional resistance training exercise, whereas the resisted sled exercise is a relatively new resistance exercise. However, as there are no studies comparing muscle activation between the exercises, the objective of this study was to examine activity of leg and trunk muscles for both exercises. Ten healthy resistance-trained men participated in a randomized crossover design study consisting of 2 preparation sessions and 2 testing sessions. Electromyographic (EMG) activity of the rectus femoris, biceps femoris, gastrocnemius, lower erector spinae, and the transversus abdominis/internal obliques (TrA/IO) were monitored during a 20-step maximum push with the weighted sled apparatus and a 10 repetition maximum with a bilateral back squat. There were nonsignificant trends for the rectus femoris (p = 0.092: 8.6-16.7%) and biceps femoris (p = 0.09: 10.5-32.8%) to demonstrate higher activity with the sled and squat exercises, respectively. There were main effects for condition with 61.2% greater gastrocnemius EMG with the sled exercise (p = 0.01) and 74.5% greater erector spinae EMG activity with the squat (p = 0.002). There were no significant differences between the exercises for the TrA/IO. In summary, the sled and squat exercises provided similar EMG activity for the quadriceps, hamstrings, and TrA/IO. The squat provided higher lower erector spinae activation, whereas the sled had superior gastrocnemius activation. Depending on the movement-training specificity of the sport, either exercise may be used in a training program while acknowledging the differences in gastrocnemius and erector spinae activity.

    To quantify trunk muscle activation levels during whole body accelerations that simulate precrash events in multiple directions and to identify recruitment patterns for the development of active human body models. Four subjects (1 female, 3 males) were accelerated at 0.55 g (net Δv = 4.0 m/s) in 8 directions while seated on a sled-mounted car seat to simulate a precrash pulse. Electromyographic (EMG) activity in 4 trunk muscles was measured using wire electrodes inserted into the left rectus abdominis, internal oblique, iliocostalis, and multifidus muscles at the L2-L3 level. Muscle activity evoked by the perturbations was normalized by each muscle's isometric maximum voluntary contraction (MVC) activity. Spatial tuning curves were plotted at 150, 300, and 600 ms after acceleration onset. EMG activity remained below 40% MVC for the three time points for most directions. At the 150- and 300 ms time points, the highest EMG amplitudes were observed during perturbations to the left (-90°) and left rearward (-135°). EMG activity diminished by 600 ms for the anterior muscles, but not for the posterior muscles. These preliminary results suggest that trunk muscle activity may be directionally tuned at the acceleration level tested here. Although data from more subjects are needed, these preliminary data support the development of modeled trunk muscle recruitment strategies in active human body models that predict occupant responses in precrash scenarios.

    Full Text Available Objective: Active straight leg raising (SLR test is advocated as a valid diagnostic method in diagnosis of sacroiliac joint (SIJ dysfunction that can assess the quality of load transfer between trunk and lower limb. The aim of this study is Comparison of changes in tonicity and activity of pelvic stabilizer muscles during active SLR, between healthy individuals and patients with sacroiliac joint pain. Materials & Methods: A case – control study was designed in 26 women (19-50 years old. With use of simple sampling, surface electromyography from rectus abdominis, external oblique, internal oblique, adductor longus, erector spine, gluteus maximus and biceps femoris was recorded in 26 subjects (15 healthy females and 11 females with sacroiliac pain in resting position and during active SLR test. Resting muscle tonicity and rms during ramp time and hold time in active SLR test were assessed by non parametric-two independent sample test. Results: Biceps femoris activity in resting position was significantly larger in patients group (P<0.05. During the active SLR, the women with sacroiliac joint pain used much less activity in some pelvic stabilizer muscles compared to the healthy subjects (P<0.05. Conclusion: The increased resting tonicity of biceps femoris and decreased activity of pelvic stabilizer muscles in subjects with sacroiliac joint pain, suggests an alteration in the strategy for lumbopelvic stabilization that may disrupt load transference through the pelvis.

    Full Text Available An animal model that allows for assessment of the degree of stretching or contraction of the implant area and the in vivo degradation properties of biological meshes is required to evaluate their performance in vivo. Adult New Zealand rabbits underwent full thickness subtotal unilateral rectus abdominis muscle excision and were reconstructed with the non-biodegradable Peri-Guard®, Prolene® or biodegradable Surgisis® meshes. Following 8 weeks of recovery, the anterior abdominal wall tissue samples were collected for measurement of the implant dimensions. The Peri-Guard and Prolene meshes showed a slight and obvious shrinkage, respectively, whereas the Surgisis mesh showed stretching, resulting in hernia formation. Surgisis meshes showed in vivo biodegradation and increased collagen formation. This surgical rabbit model for abdominal wall defects is advantageous for evaluating the in vivo behaviour of surgical meshes. Implant area stretching and shrinkage were detected corresponding to mesh properties, and histological analysis and stereological methods supported these findings.

    Magnetic Resonance-guided Focused Ultrasound Surgery (MRgFUS) is a non-invasive method to treat uterine fibroids. To help determine the patient suitability for MRgFUS, we propose a new objective measure: the scaled signal intensity (SSI) of uterine fibroids in T2 weighted MR images (T2WI). Forty three uterine fibroids in 40 premenopausal women were included in this retrospective study. SSI of each fibroid was measured from the screening T2WI by standardizing its mean signal intensity to a 0-100 scale, using reference intensities of rectus abdominis muscle (0) and subcutaneous fat (100). Correlation between the SSI and the non-perfused volume (NPV) ratio (a measure for treatment success) was calculated. Pre-treatment SSI showed a significant inverse-correlation with post treatment NPV ratio (p < 0.05). When dichotomizing NPV ratio at 45 %, the optimal cut off value of the SSI was found to be 16.0. A fibroid with SSI value 16.0 or less can be expected to have optimal responses. The SSI of uterine fibroids in T2WI can be suggested as an objective parameter to help in patient selection for MRgFUS. (orig.)

    Studies show some return of breast sensation after breast reconstruction; however, recovery is variable and unpredictable. Efforts are being made to restore innervation by reattaching nerves (neurotization). We sought to systematically review the literature addressing breast sensation after reconstruction. The following databases were searched: EMBASE, Cochrane, and PubMed. Additionally, the PLASTIC AND RECONSTRUCTIVE SURGERY journal was hand searched from 1960 to 2009. Inclusion criteria included breast reconstruction for cancer, return of sensation with objective results, and patients aged 18 to 90 years. Studies with purely cosmetic procedures, case reports, studies with less than 10 patients, and studies involving male patients were excluded. The initial search yielded 109 studies, which was refined to 20 studies with a total pool of 638 patients. Innervated flaps have a greater magnitude of recovery, which occurs at an earlier stage compared with the noninnervated flaps. Overall, sensation to deep inferior epigastric artery perforator flaps may recover better sensation than transverse rectus abdominis myocutaneous flaps, followed by latissimus dorsi flaps, and finally implants. Women's needs and expectations for sensation have led plastic surgeons to investigate ways to facilitate its return. Studies, however, depict conflicting data. Larger series are needed to define the role of neurotization as a modality for improving sensory restoration. Thieme Medical Publishers.

    Immediate breast reconstruction has become a standard of care following mastectomy for cancer, largely due to improved esthetic and psychologic outcomes achieved with this technique. However, the current historical standards--transverse rectus abdominis myocutaneous flap reconstruction and expander--implant surgery-still have limitations as regards patient morbidity, short-term body-image improvements, and even cost. To address these shortcomings, we employ a novel concept of human tissue replacement to enhance breast shape and provide total coverage, enabling immediate mound reconstruction without the need for breast expansion prior to permanent implant placement. AlloDerm (human acellular tissue matrix) is a human-derived graft tissue with extensive experience in various settings of skin and soft tissue replacement surgery. This report describes the success using acellular tissue matrix to provide total coverage over the prosthesis in immediate reconstruction, with limited muscle dissection. In this population, 49 patients (76 breasts) successfully underwent the acellular tissue matrix-based immediate reconstruction, resulting in durable breast reconstruction with good symmetry. These findings may predict that acellular tissue matrix-supplemented immediate breast reconstruction will become a new technique for the immediate reconstruction of the postmastectomy breast.

    The effect of meat cooking was measured on myofibrillar proteins from bovine M. Rectus abdominis. The heating treatment involved two temperatures (100 degrees C during 5, 15, 30, and 45 min and 270 degrees C during 1 min). Protein oxidation induced by cooking was evaluated by the level of carbonyl and free thiol groups. Structural modifications of proteins were assessed by the measurement of their surface hydrophobicity and by their aggregation state. With the aim of evaluating the impact of heat treatment on the digestive process, myofibrillar proteins were then exposed to proteases of the digestive tract (pepsin, trypsin, and alpha-chymotrypsin) in conditions of pH and temperature that simulate stomach and duodenal digestion. Meat cooking affected myofibrillar protein susceptibility to proteases, with increased or decreased rates, depending on the nature of the protease and the time/temperature parameters. Results showed a direct and quantitative relationship between protein carbonylation (p<0.01) and aggregation (p<0.05) induced by cooking and proteolytic susceptibility to pepsin. However, no such correlations have been observed with trypsin and alpha-chymotrypsin.

    Little research has been reported on the effects of using different devices with resistance exercises in a water environment. This study compared muscular activation of lower extremity and core muscles during leg adduction performed at maximum velocity with drag and floating devices of different sizes. A total of 24 young men (mean age 23.20 ± 1.18 years) performed 3 repetitions of leg adduction at maximum velocity using 4 different devices (ie, large/small and drag/floating). The maximum amplitude of the electromyographic root mean square of the adductor longus, rectus abdominis, external oblique on the dominant side, external oblique on the nondominant side, and erector lumbar spinae were recorded. Electromyographic signals were normalized to the maximum voluntary isometric contraction (MVIC). Unexpectedly, no significant (P > 0.05) differences were found in the neuromuscular responses among the different devices used; the average activation of agonist muscle adequate for neuromuscular conditioning was 40.95% of MVIC. In addition, external oblique activation is greater on the contralateral side to stabilize the body (average, 151.74%; P < 0.05). Therefore, if maximum muscle activation is required, the kind of device is not relevant. Thus, the choice should be based on economic factors.

    To compare muscle activation patterns in 14 dominant side muscles during different yoga poses across three skill levels. Mixed repeated-measures descriptive study. University neuromuscular research laboratory, Miami, US. A group of 36 yoga practitioners (9 M/27 F; mean ± SD, 31.6 ± 12.6 years) with at least 3 months yoga practice experience. Each of the 11 surya namaskar poses A and B was performed separately for 15s and the surface electromyography for 14 muscles were recorded. Normalized root mean square of the electromyographic signal (NrmsEMG) for 14 muscles (5 upper body, 4 trunk, 5 lower body). There were significant main effects of pose for all fourteen muscles except middle trapezius (p<.02) and of skill level for the vastus medialis; p=.027). A significant skill level × pose interaction existed for five muscles (pectoralis major sternal head, anterior deltoid, medial deltoid, upper rectus abdominis and gastrocnemius lateralis; p<.05). Post hoc analyses using Bonferroni comparisons indicated that different poses activated specific muscle groups; however, this varied by skill level. Our results indicate that different poses can produce specific muscle activation patterns which may vary due to practitioners' skill levels. This information can be used in designing rehabilitation and training programs and for cuing during yoga training. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The aim of this study was to determine the effects of Chinese martial arts practice on postural reaction control after perturbation. Participants standing in Romberg tandem posture were subjected to an unexpected lateral platform translation with the eyes open or closed at two translation amplitudes. The peak displacement of the centre of pressure and of the centre of mass, and the onset latency of muscular activity (tibialis anterior, gastrocnemius, lumbodorsal muscular group, and rectus abdominis), were evaluated for martial arts practitioners and for sport and non-sport participants. Compared with the sport and non-sport participants, the martial arts group showed lower maximal centre of pressure and centre of mass peak displacements in both the lateral and anterior - posterior directions, but no difference was found in the onset of muscular responses. We conclude that martial arts practice influences postural reaction control during a fixed-support strategy in a tandem task. The martial arts group used the ankle joint more frequently than the sport and non-sport participants, especially in the eyes-closed conditions. Our results suggest that the better balance recovery in the martial arts group is a consequence of better control of biomechanical properties of the lower limbs (e.g. through muscular response by co-contraction), not a change in the neuromuscular temporal pattern.

    This study examined anterior chain whole body linkage exercises, namely the body saw, hanging leg raise and walkout from a push-up. Investigation of these exercises focused on which particular muscles were challenged and the magnitude of the resulting spine load. Fourteen males performed the exercises while muscle activity, external force and 3D body segment motion were recorded. A sophisticated and anatomically detailed 3D model used muscle activity and body segment kinematics to estimate muscle force, and thus sensitivity to each individual's choice of motor control for each task. Gradations of muscle activity and spine load characteristics were observed across tasks. On average, the hanging straight leg raise created approximately 3000 N of spine compression while the body saw created less than 2500 N. The hanging straight leg raise created the highest challenge to the abdominal wall (>130% MVC in rectus abdominis, 88% MVC in external oblique). The body saw resulted in almost 140% MVC activation of the serratus anterior. All other exercises produced substantial abdominal challenge, although the body saw did so in the most spine conserving way. These findings, along with consideration of an individual's injury history, training goals and current fitness level, should assist in exercise choice and programme design.

    Full Text Available As microvascular techniques continue to improve, perforator flap free tissue transfer is now the gold standard for autologous breast reconstruction. Various options are available for breast reconstruction with autologous tissue. These include the free transverse rectus abdominis myocutaneous (TRAM flap, deep inferior epigastric perforator flap, superficial inferior epigastric artery flap, superior gluteal artery perforator flap, and transverse/vertical upper gracilis flap. In addition, pedicled flaps can be very successful in the right hands and the right patient, such as the pedicled TRAM flap, latissimus dorsi flap, and thoracodorsal artery perforator. Each flap comes with its own advantages and disadvantages related to tissue properties and donor-site morbidity. Currently, the problem is how to determine the most appropriate flap for a particular patient among those potential candidates. Based on a thorough review of the literature and accumulated experiences in the author’s institution, this article provides a logical approach to autologous breast reconstruction. The algorithms presented here can be helpful to customize breast reconstruction to individual patient needs.

    Full Text Available Shortened hamstrings are likely to restrict the anterior pelvic tilt and induce a slumped posture due to the posterior pelvic tilt. This study was conducted to compare the effects of proprioceptive neuromuscular facilitation (PNF stretching and modified anterior pelvic tilt taping (APTT on hamstring shortness-associated pelvic compensation while executing seated double-knee extension. Male college students (28 healthy young adults; mean age: 21.4 ± 2.1 years with hamstring shortness were recruited as study subjects and randomly assigned to either the PNF stretching group (control group or the APTT group (experimental group. In all the subjects, changes in the movement distance of the centre of gluteal pressure (COGP as well as rectus abdominis (RA and semitendinosus (SEM muscle activities were measured during seated double-knee extension while the respective intervention method was applied. Both groups showed significant decreases in COGP distance and RA muscle activity compared with their respective baseline values (p < 0.05, however, no significant changes were observed in SEM muscle activity. We can infer that not only a direct intervention on the hamstring, such as PNF stretching, but also a modified APTT-mediated pelvic intervention may be used as a method for reducing pelvic compensation induced by hamstring shortness.

    This study aimed to evaluate the validity and test-retest reliability of trunk muscle strength testing performed with a latest-generation isokinetic dynamometer. Eccentric, isometric, and concentric peak torque of the trunk flexor and extensor muscles was measured in 15 healthy subjects. Muscle cross sectional area (CSA) and surface electromyographic (EMG) activity were respectively correlated to peak torque and submaximal isometric torque for erector spinae and rectus abdominis muscles. Reliability of peak torque measurements was determined during test and retest sessions. Significant correlations were consistently observed between muscle CSA and peak torque for all contraction types (r=0.74-0.85; Ptorque (r ⩾ 0.99; Ptorque between test and retest ranged from -3.7% to 3.7% with no significant mean directional bias. Overall, our findings establish the validity of torque measurements using the tested trunk module. Also considering the excellent test-retest reliability of peak torque measurements, we conclude that this latest-generation isokinetic dynamometer could be used with confidence to evaluate trunk muscle function for clinical or athletic purposes.

    1995-04-01

    The cases of 15 patients are presented where microvascular soft-tissue reconstructions became necessary after internal fixation of tibial fractures. Primarily, seven of the fractures were closed. Eleven fractures had originally been treated by open reduction and internal fixation using plates and screws, and four by intramedullary nailing. All of the patients suffered from postoperative complications leading to exposure of the bone or fixation material. The internal fixation material was removed and radical revision of dead and infected tissue was carried out in all cases. Soft tissue reconstruction was performed using a free microvascular muscle flap (11 latissimus dorsi, three rectus abdominis, and one gracilis). In eight cases the nonunion of the fracture indicated external fixation. The microvascular reconstruction was successful in all 15 patients. In one case the recurrence of deep infection finally indicated a below-knee amputation. In another case, chronic infection with fistulation recurred postoperatively. After a mean follow-up of 26 months the soft tissue coverage was good in all the remaining 13 cases. All the fractures united. Microvascular free muscle flap reconstruction of the leg is regarded as a reliable method for salvaging legs with large soft-tissue defects or defects in the distal leg. If after internal fixation of the tibial fracture the osteosynthesis material or fracture is exposed, reconstruction of the soft-tissue can successfully be performed by free flap transfer. By radical revision, external fixation, bone grafting, and a free flap the healing of the fracture can be achieved.

    A total of 35 flap reconstructions were done to cover exposed calcaneal bones in 31 patients. All patients had calcaneal fractures, 19 of which were primarily open. Soft tissue reconstruction for the closed fractures was indicated by a postoperative wound complication. A microvascular flap was used for reconstruction in 21 operations (gracilis, n = 11; anterolateral thigh, n = 5; rectus abdominis, n = 3; and latissimus dorsi, n = 2). A suralis neurocutaneous flap was used in eight, local muscle flaps in three, and local skin flaps in three cases. The mean follow-up time was 14 months (range 3 months-4 years). One suralis flap failed and was replaced by a latissimus dorsi flap. Necrosis of the edges that required revision affected three flaps. Deep infection developed in two patients and delayed wound healing in another four. During the follow-up the soft tissues healed in all patients and there were no signs of calcaneal osteitis. Flaps were considered too bulky in five patients. Soft tissues heal most rapidly with microvascular flaps. In the long term, gracilis muscle covered with free skin grafts gives a good contour to the foot. The suralis flap is reliable and gives a good final aesthetic outcome. Local muscles can be transposed for reconstruction in small defects.

  13. Oxidative proteome alterations during skeletal muscle ageing

    Full Text Available Sarcopenia corresponds to the degenerative loss of skeletal muscle mass, quality, and strength associated with ageing and leads to a progressive impairment of mobility and quality of life. However, the cellular and molecular mechanisms involved in this process are not completely understood. A hallmark of cellular and tissular ageing is the accumulation of oxidatively modified (carbonylated proteins, leading to a decreased quality of the cellular proteome that could directly impact on normal cellular functions. Although increased oxidative stress has been reported during skeletal muscle ageing, the oxidized protein targets, also referred as to the ‘oxi-proteome’ or ‘carbonylome’, have not been characterized yet. To better understand the mechanisms by which these damaged proteins build up and potentially affect muscle function, proteins targeted by these modifications have been identified in human rectus abdominis muscle obtained from young and old healthy donors using a bi-dimensional gel electrophoresis-based proteomic approach coupled with immunodetection of carbonylated proteins. Among evidenced protein spots, 17 were found as increased carbonylated in biopsies from old donors comparing to young counterparts. These proteins are involved in key cellular functions such as cellular morphology and transport, muscle contraction and energy metabolism. Importantly, impairment of these pathways has been described in skeletal muscle during ageing. Functional decline of these proteins due to irreversible oxidation may therefore impact directly on the above-mentioned pathways, hence contributing to the generation of the sarcopenic phenotype.

    Presacral venous haemorrhage during rectal movement is low, but is often massive, and even fatal. Our objective is the "in vitro" determination of the results of electrocoagulation applied to a fragment of muscle on the sacral bone surface during rectal resection due to a malignant neoplasm of the rectum. Single-pole coagulation was applied "in vitro" with the selector at maximum power on a 2×2 cms muscle fragment, applied to the anterior side of the IV sacral vertebra until reaching boiling point. The method was used on 6 patients with bleeding of the presacral venous plexus. In the "in vitro" study, boiling point was reached in 90 seconds from applying the single-pole current on the muscle fragment. Electrocoagulation was applied to a 2×2 cm rectal muscle fragment in 6 patients with presacral venous haemorrhage, using pressure on the surface of the presacral bone, with the stopping of the bleeding being achieved in all cases. The use of indirect electrocoagulation on a fragment of the rectus abdominis muscle is a straightforward and highly effective technique for controlling presacral venous haemorrhage.

    To analyze the effect of Pilates principles on the EMG activity of abdominal and paraspinal muscles on stable and unstable surfaces. Surface EMG data about the rectus abdominis (RA), iliocostalis (IL) and lumbar multifidus (MU) of 19 participants were collected while performing three repetitions of a crunch exercise in the following conditions: 1) with no Pilates technique and stable surface (nP + S); 2) with no Pilates technique and unstable surface (nP + U); 3) with Pilates technique and stable surface (P + S); 4) with Pilates and unstable surface (P + U). The EMG Fanalysis was conducted using a custom-made Matlab(®) 10. There was no condition effect in the RA iEMG with stable and unstable surfaces (F(1,290) = 0 p = 0.98) and with and without principles (F(1,290) = 1.2 p = 0.27). IL iEMG was higher for the stable surface condition (F(1,290) = 32.3 p Pilates principles (F(1,290) = 21.9 p Pilates principles (F(1,290) = 84.9 p < 0.001). Copyright © 2014 Elsevier Ltd.

    Various stimuli such as the flexibility of lumbopelvic structures influence the neuromuscular responses of the trunk musculature, leading to different load sharing strategies and reflex muscle responses from the afferents of lumbopelvic mechanoreceptors. This link between flexibility and neuromuscular response has been poorly studied. The aim of this study was to investigate the relationship between lumbopelvic flexibility and neuromuscular responses of the erector spinae, hamstring and abdominal muscles during trunk flexion-extension. Lumbopelvic movement patterns were measured in 29 healthy women, who were separated into two groups according to their flexibility during trunk flexion-extension. The electromyographic responses of erector spinae, rectus abdominis and biceps femoris were also recorded. Subjects with greater lumbar flexibility had significantly less pelvic flexibility and vice versa. Subjects with greater pelvic flexibility had a higher rate of relaxation and lower levels of hamstring activation during maximal trunk flexion. The neuromuscular response patterns of the hamstrings seem partially modulated by pelvic flexibility. Not so with the lumbar erector spinae and lumbar flexibility, despite the assertions of some previous studies. The results of this study improve our knowledge of the relationships between trunk joint flexibility and neuromuscular responses, a relationship which may play a role in low back pain.

    A radiation-induced brachial plexopathy after a mastectomy causes severe pain and numbness, as well as motor and sensory disorders. Severe pain is often resistant to analgesic blocks, and in most instances, the effect of neurolysis is only temporary. We have treated two such patients with microsurgical neurolysis and then have covered the nerve by transferred muscles. In one case, the exposed brachial plexus was covered with a pedicled latissimus dorsi muscle flap, and in the other, with a free rectus abdominis muscle flap. Pain and numbness were markedly improved in these two patients soon after the surgery, and the improvement in the sensory function also was relatively satisfactory. In one case, the motor function also improved. These patients have had no recurrence of pain or numbness for 4 years and 2 months and 4 years and 7 months after surgery, respectively. Further, their sensory and motor disorders did not advance. Surgical indications for a radiation-induced brachial plexopathy remain controversial, since the operation does not always ensure a marked improvement in the sensory and motor functions. Further, the operation is ineffective for patients with advanced nerve degeneration. Taking these factors into consideration, the preoperative predication of beneficial effects from this surgery is difficult. Despite our limited experience, however, our surgical method has been thought to be effective because it achieves a marked improvement in the numbness and pain experienced in the arms, which are usually the patients' chief complaints.

    Full Text Available Some pharmacodynamic effects of cefepime, a new injectable semisynthetic cephalosporin, were studied in laboratory animals and the following results were obtained. Cefepime maximally stimulated isolated guinea pig's ileum, rat's colon (80 μg/mL bath, and rabbit's duodenum (400 μg/mL bath. Contrarily, complete relaxation of isolated rat's fundic strip was produced by 80 μg/mL bath. Effects of cefepime on isolated rat's uterine muscle were different according to stage of sex cycle. Cefepime did not induce any effects on the resting tonus of isolated guinea pig's tracheal chain and rabbit's aortic strip. Concentrations of 200 and 400 μg/mL bath induced marked inhibition in the force of muscular twitches of the isolated frog's gastrocnemius muscle which was less potent than that induced by procaine hydrochloride 2%. Cefepime completely blocked the neuromuscular transmission of frog's rectus abdominis muscle (40 μg/mL bath and rat's phrenic nerve hemidiaphragm preparation (200 μg/mL bath. This blockade was reversed by acetylcholine and neostigmine. Cefepime produced dose-dependent negative inotropic effect on isolated rabbit's heart and guinea pig's auricles. There were no changes in blood pressure and rate of respiration in anaesthetized dog after cefepime injection. These findings indicate that cefepime has a low potential to produce adverse reactions at therapeutic doses.

    This study examined trunk muscle activation, balance and proprioception while squatting with a water-filled training tube (WT) and a traditional barbell (BB), with either closed (CE) or open eyes (OE). Eighteen male elite Gaelic footballers performed an isometric squat under the following conditions: BB-OE, BB-CE, WT-OE and WT-CE. The activity of rectus abdominis (RA), external oblique (EO) and multifidus (MF) was measured using electromyography, along with sway of the centre of pressure (CoP) using a force platform. Only the EO and the MF muscles exhibited an increased activity with WT (p velocity and range of the CoP increased significantly with WT (p velocity of the CoP was marginally reduced (d = 0.29). WT elicited a greater level core muscle activation and created a greater challenge to postural stability when compared to a BB. It appears that WT does not benefit from vision but emphasises the somatosensory control of balance. The use of WT may be beneficial in those sports requiring development of somatosensory/proprioceptive contribution to balance control.

    The aim of this study was to examine the effect of fatigue during one set of 6-RM bench pressing upon the muscle patterning and performance. Fourteen resistance-trained males (age 22.5±2.0 years, stature 1.82±0.07 m, body mass 82.0±7.8 kg) conducted a 6-RM bench press protocol. Barbell kinematics and EMG activity of pectoralis major, deltoid anterior, biceps brachii, triceps brachii, rectus abdominis, oblique external and erector spinae were measured in each repetition during the 6-RM bench press. Total lifting time increased and the velocity in the ascending movement decreased (p≤0.001). However, the kinematics in the descending phase deferred: the time decreased and velocity increased during the 6-RM (p≤0.001). Generally, muscles increased their EMG amplitude during the six repetitions in the ascending movement, while only three of the seven measured muscles showed an increase over the six repetitions in the descending part in 6-RM bench pressing. It was concluded that the bench pressing performance decreased (lower barbell velocities and longer lifting times) with increasing fatigue in the 6-RM execution. Furthermore EMG increased in the prime movers and the trunk stabilizers (abdominal and spine), while the antagonist muscle (biceps) activity was not affected by fatigue during the lifting phase in a single set of 6-RM bench pressing.

    [Purpose] Elderly smokers have a reduced chest diameter due to weakening of the respiratory muscles, and this results in decreased ventilation, leading to a vicious circle. Therefore, the present study investigated the effects of an intervention program to enhance the pulmonary function and muscle activity of elderly smokers. [Subjects and Methods] Participants were randomly assigned to one of two experimental groups or a control (CG) group. The experimental groups performed exercises three times per week for six weeks, whereas the CG performed no exercises. One of the experimental groups performed a Feedback Breathing Exercise (FBE) for 15 minutes, and the other repeated three sets of Balloon-Blowing Exercises (BBE) with sufficient rest of more than one minute between sets. [Results] In the experimental groups, FVC, FEV1/FVC, PEF and muscle activity of the rectus abdominis significantly improved after four weeks, but no significant differences were observed in FEV1 or VC after six weeks. [Conclusion] The results show that FBE and BBE improved the pulmonary functions of elderly smokers, demonstrating the potential benefits of the development of various training methods using balloons, and group programs, including recreational factors, for increasing respiratory muscles strength.

    Breast reconstruction has become an available option for most patients undergoing mastectomy: in fact many authors agree that breast reconstruction does not interfere with possible therapies and improves the quality of life of women. The aim of the study was to evaluate the psychological adjustment of patients who had immediate or delayed reconstruction using 2 different methods: implants and autologous tissues. The study population (115 patients) was derived from patients who underwent breast reconstruction in the period January 1988-December 1991, in follow-up at the Department of Plastic and Reconstructive Surgery; no patient was undergoing psychological therapy. 58 patients underwent breast reconstruction using implants and 57 using Transverse Rectus Abdominis Myocutaneous Flap (TRAMF). Informations were gathered, including the patient's age, the number of offspring, the marital status, the scholastic education, the job and the relapse between mastectomy and reconstruction. The psychological instruments consisted in three standardized self-administered questionnaires: Psychological Distress Inventory (PDI), State Trait Anxiety Inventory form Y (STAI), Eysenk Personality Inventory (EPQ-R). These tests were chosen to gauge the psychological distress, such anxiety, anger, depression and psychosocial maladjustment. To better perform the changes of body image after breast reconstruction, women were requested to answer three more specific questions about the sexual desire, physical image and social relationships. The 102 patients assessed in this study indicate low incidence of psychological distress and adaptive coping strategies. Impairment was reported, regarding body image, by patients undergoing delayed reconstruction; in these patients higher scores in distress tests were observed.

    Abdominal strengthening exercises are important for stroke patients; however, there is a lack of research on therapeutic exercises for increasing abdominal muscle activity in stroke patients. We investigated the effects of non-paretic arm exercises using a tubing band on abdominal muscle activity in stroke patients. In total, 18 hemiplegic subjects (13 males, 5 females) were recruited. All subjects performed non-paretic arm exercises involving three different shoulder movements (extension, flexion, and horizontal abduction) using an elastic tubing band. Surface electromyography (EMG) signals were recorded from the rectus abdominis (RA), external oblique (EO), and internal oblique (IO) muscles bilaterally during non-paretic arm exercises. EMG activities of abdominal muscles during non-paretic arm extension and horizontal abduction were increased significantly versus shoulder flexion when subjects performed the arm exercise in a seated position. Muscle activity of the EO was significantly greater in the paretic than the non-paretic side during non-paretic arm extension and horizontal abduction. We suggest that non-paretic arm extension and horizontal abduction exercises using an elastic tubing band may be effective in increasing abdominal muscle activity.
