  2. Experiment and speculation in seventeenth-century Italy: The case of Geminiano Montanari.

    Science.gov (United States)

    Vanzo, Alberto

    2016-04-01

    This paper reconstructs the natural philosophical method of Geminiano Montanari, one of the most prominent Italian natural philosophers of the late seventeenth century. Montanari's views are used as a case study to assess recent claims concerning early modern experimental philosophy. Having presented the distinctive tenets of seventeenth-century experimental philosophers, I argue that Montanari adheres to them explicitly, thoroughly, and consistently. The study of Montanari's views supports three claims. First, experimental philosophy was not an exclusively British phenomenon. Second, in spite of some portrayals of experimental philosophy as an 'atheoretical' or 'purely descriptive' enterprise, experimental philosophers could consistently endorse a variety of natural philosophical explanations and postulate theoretical entities. Third, experimental philosophy and mechanical philosophy were not, as such, antagonistic. They could be consistently combined in a single philosophical enterprise. Copyright © 2015 The Author.

    Pathological abnormality of the peroneal tendons is an under-appreciated source of lateral hindfoot pain and dysfunction that can be difficult to distinguish from lateral ankle ligament injuries. Enclosed within the lateral compartment of the leg, the peroneal tendons are the primary evertors of the foot and function as lateral ankle stabilisers. Pathology of the tendons falls into three broad categories: tendinitis and tenosynovitis, tendon subluxation and dislocation, and tendon splits and tears. These can be associated with ankle instability, hindfoot deformity and anomalous anatomy such as a low lying peroneus brevis or peroneus quartus. A thorough clinical examination should include an assessment of foot type (cavus or planovalgus), palpation of the peronei in the retromalleolar groove on resisted ankle dorsiflexion and eversion as well as testing of lateral ankle ligaments. Imaging including radiographs, ultrasound and MRI will help determine the diagnosis. Treatment recommendations for these disorders are primarily based on case series and expert opinion. The aim of this review is to summarise the current understanding of the anatomy and diagnostic evaluation of the peroneal tendons, and to present both conservative and operative management options of peroneal tendon lesions.

    2016-01-01

    Full Text Available En Lira de Lixo , Adriano Scandolara elabora poéticamente una experiencia social típica de la modernidad relacionada con la vida en un gran centro urbano (en este caso, Curitiba del siglo XXI. Esta experiencia puede ser sentida no sólo en el tema desarrollado en los poemas del autor, pero t ambién en los determinantes formales de su poesía. El libro combina una visión nihilista de la existencia, que rechaza la vida y la historia como unidades de sentido, con una forma fragmentada (alegórica, que rompe con la noción clásica de la obra de arte orgánica. El análisis sigue con el propósito de poner la poesía de Scandolara en contacto con el pensamiento de Walter Benjamin acerca de la vida moderna y su expresión en las artes.

  6. Magnetic resonance imaging findings in patients with peroneal tendinopathy and peroneal tenosynovitis

    To compare the magnetic resonance (MR) imaging findings of a group of patients with clinically diagnosed peroneal tendonopathy and peroneal tenosynovitis with the MR imaging findings of a control group of patients with no clinical evidence of peroneal tendon disorder. The MR examinations of 24 patients with symptomatic peroneal tendinopathy or peroneal tenosynovitis and 70 patients with no clinical evidence of peroneal tendon disorder were retrospectively reviewed to determine the presence or absence of four MR imaging findings: 1) predominantly or uniform intermediate signal intensity within the peroneal tendons on one or more axial proton density-weighted images, 2) predominantly or uniform intermediate signal intensity within the peroneal tendons on three consecutive axial proton density-weighted images, 3) intermediate T2 signal intensity within the peroneal tendons, and 4) circumferential fluid within the common peroneal tendon sheath greater than 3 mm in maximal width. The sensitivity and specificity of these MR imaging findings for determining the presence or absence or symptomatic peroneal tendinopathy or peroneal tenosynovitis were calculated. The sensitivity of MR imaging findings 1, 2, 3, and 4 for determining the presence of peroneal tendinopathy or peroneal tenosynovitis were 92%, 92%, 50%, and 17% respectively. The specificity of MR imaging findings 1, 2, 3, and 4 for determining the absence of peroneal tendinopathy or peroneal tenosynovitis were 57%, 79%, 93%, and 100% respectively. The presence of predominantly or uniform intermediate signal intensity within the peroneal tendons on three consecutive axial proton density-weighted images is a highly sensitive and moderately specific indicator of symptomatic peroneal tendinopathy. The presence of intermediate T2 signal within the peroneal tendons, and the presence of circumferential fluid within the peroneal tendon sheath greater than 3 mm in maximal width, are highly specific indicators of peroneal

    Full Text Available Memorie di Adriano, a play staged by Maurizio Scaparro in 1989 in the setting of Hadrian’s Villa, offers a major example of dramaturgy based on a non-dramatic source, a kind of drama more and more common nowadays, but quite unusual for a renowned director. Nonetheless, the play represents a coherent example of Scaparro’s peculiar dramatic research.

    Background For large tongue defects, reconstructive surgeons have devised a variety of feasible options, such as radial forearm free flap and anterolateral thigh (ALT) flap. In our institution, peroneal flap has been the workhorse flap for the soft tissue defect in head and neck reconstruction. We present our experience using peroneal flap in tongue reconstruction. Patients and Methods The study included 47 patients who had undergone tongue reconstructions with peroneal flaps after tumor resection. The size and location of the defect after tumor resection determined whether the peroneal flaps could be harvested as pure septocutaneous flaps to solely reconstruct the neotongue or to carry an additional muscle bulk to fill the adjacent defect. Retrospective chart review was used to look for postoperative complications and to perform functional assessments (which were also performed through telephone inquiry). Results Of the 47 patients, 3 (6%) had flap failure and 1 (2.1%) had partial flap necrosis. The hemiglossectomy group had better results than the total glossectomy group with respect to speech and diet, but neither of these results reached statistical significance (p = 1.0 for speech and p = 0.06 for diet). The results of the subtotal glossectomy group were better than those of the total glossectomy group with respect to diet (p = 0.03). No statistically significant differences were noted among the three groups with respect to cosmetic aspect (p = 0.64). Conclusions Considering its reasonable postoperative complication rates and functional results, peroneal flap can be considered a feasible option for tongue reconstruction.

    Full Text Available Intrasheath subluxation of the peroneal tendons within the peroneal groove is an uncommon problem. Open exploration combined with a peroneal groove-deepening procedure and retinacular reefing is the recommended treatment. This extensive lateral approach needs incision of the intact superior peroneal retinaculum and repair afterwards. We treated three patients with a painful intrasheath subluxation using an endoscopic approach. During this tendoscopy both tendons were inspected. The distal muscle fibers of the peroneus brevis tendon were resected in two patients. A partial tear was debrided in the third patient. All patients had a good result. No wound-healing problems or other complications occurred. Early return to work and sports was possible. An endoscopic approach was successful in treatment of an intrasheath subluxation of the peroneal tendons.

    2016-01-01

    Full Text Available The authors analyzed scientific literature in respect of various issues in treatment of athletes with peroneal muscles lesions starting from 1987 till 2016. Key search and publications selection was made in PubMed and russian national electronic scientific library eLIBRARY. Peroneal tendons pathology is not the major but the underestimated cause of pain in lateral and hindfoot as well as of foot dysfunction which is difficult to distinguish from lesions of lateral ligaments of the ankle joint. Untreated lesions of peroneal tendons can result in chronic ankle pain and significant functional disorders. The purpose of the present paper is to improve the current comprehension of anatomy, to identify factors contributing to pathology, to perform diagnostic evaluation of peroneal tendons and to review current treatment options of such lesions.

  13. Lateral meniscal cyst causing common peroneal palsy

    Lateral meniscal cysts are relatively common, but only in rare instances do they cause common peroneal nerve irritation. There are, we believe, no cases reported in which both the sensory and motor functions of the nerve have been compromised. We present a case of a lateral meniscal cyst that became palpable and led to symptoms of numbness and weakness in the distribution of the common peroneal nerve. The MRI findings were of an oblique tear of the lateral meniscus with an associated multiloculated meniscal cyst that coursed behind the biceps tendon before encroaching on the common peroneal nerve. Surgical resection confirmed the tract as located on the MRI and histology confirmed the mass to be a synovial cyst. Resection of the cyst and arthroscopic excision of the meniscal tear led to resolution of the symptoms in 3 months. (orig.)

    The proportion of patients with clinical findings referable to peroneal pathology and magnetic resonance imaging (MRI)-diagnosed peroneal tendon pathology is unknown. Previous studies have correlated surgical findings with clinical data and preoperative MRI, but there are no published studies that reference clinical examination findings to imaging findings. To determine the relationship between peroneal tendon pathology as diagnosed by MRI and clinical findings of peroneal tendon pathology. Fifty-six patients who had both MRI evidence of peroneal tendon pathology and an associated clinical examination of the ankle were evaluated over a 3-year period at a tertiary care institution. Clinical examination criteria included lateral ankle tenderness, dislocation/snapping, and lateral ankle pain. A board-certified, fellowship-trained musculoskeletal radiologist confirmed the presence of MRI findings consistent with peroneal tendon pathology. Of the 56 patients with positive findings on MRI, 27 patients had an associated positive clinical exam and 29 patients had a negative clinical exam. The positive predictive value of MRI for peroneal tendon tears with positive clinical findings was 48% (95% confidence interval = 35% to 61%). Patients with MRI findings of peroneal tendon pathology should undergo careful clinical examination, as the positive predictive value of MRI for peroneal tendon pathology with actual clinical findings is low. This study demonstrates that peroneal tendon tears are often incidental findings on MRI.

    Full Text Available During the sixteenth and seventeenth centuries many reports and travel narratives helped to create a more positive image of China around the world. The remarkable efforts of the Society of Jesus were essential to this new view, thanks to a unique policy of evangelization and the personal and ethnographic contributions of some of its members. However, through a comparative analysis of narratives from Diego de Pantoja and Adriano de las Cortes (both Jesuits, we can see how the texts are not just standard doctrinal narratives but also contain personal experiences, selections, interpretations and creative evaluations capable of transforming the reality.

    Durante los siglos XVI y XVII muchos informes y relatos de viajes contribuyeron a crear una imagen positiva de China. En este empeño destacó la Compañía de Jesús gracias a una singular política de evangelización y a las aportaciones personales y etnográficas de algunos de sus miembros. Sin embargo, mediante un análisis comparativo de las narrativas de Diego de Pantoja y Adriano de las Cortes, ambos jesuitas, se muestra cómo los textos no sólo son doctrina y norma sino también experiencia personal, selección, interpretación y creatividad valorativa capaces de transformar la realidad.

    Peroneal tendon tears are relatively common injuries that seem to have a poor healing tendency. The discussion goes that peroneal tendons have avascular zones, contributing to the poor healing of those tears. The purpose of this study was to provide evidence on the vascularization pattern of the peroneal tendons. Ten adult fresh-frozen cadavers were obtained from a university-affiliated body donation programme. The femoral artery was injected with natural coloured latex at the level of the knee. Macroscopic and microscopic dissections were performed to visualize the vascularization towards the peroneal tendons. To expose intratendinous vascularity, the tendons were cleared using a modified Spälteholz technique. In all specimens, blood was mainly supplied by the peroneal artery through a posterolateral vincula connecting both tendons. Branches were bifurcated every 3.9 ± 1.8 cm, starting 24 ± 5.3 cm proximal to the tip of the fibula. Eight out of 10 (80%) specimens had poor vascularized zones in the peroneus longus tendon. No avascular zones were found in the peroneus brevis tendon. The peroneal tendons are well vascularized by the peroneal artery, via vessels running through a common vincula for both tendons. In the peroneus brevis, no avascular zones were found. To keep the tendons well vascularized and therefore improve tendon healing, surgeons should be careful leaving the vincula intact during surgical procedures.

  18. Early detection of peroneal neuropathy by ultrasound

    Full Text Available A 12 year old boy presented with ankle sprain. The physical examination revealed mild weakness of ankle dorsiflexion. An ultrasound was done for the soft tissues of the ankle. In addition to relative atrophy of the peroneus longus muscle, a compressive common peroneal nerve (CPN lesion with a synovial cyst at the level of the proximal tibiofibular joint (PTFJ was accidently found. Since there were features of CPN compression by the synovial cyst, total excision of the cyst was performed. After the operation, muscle strength improved and the neurological deficit subsided. Therefore, the early diagnosis of PTFJ synovial cyst with nerve injury was crucial in order to achieve a better result. The obscure nature of clinical presentations can delay the diagnosis, which may potentially lead to a poor prognosis after treatment in such cases. This report highlights the fact that ankle sprain do need a thorough clinical work up in some cases.

    BACKGROUND: Many diseases of the common peroneal nerve are a result of sciatic nerve injury. The present study addresses whether anatomical positioning of the sciatic nerve is responsible for these injuries. OBJECTIVE: To analyze anatomical causes of sciatic nerve and common peroneal nerve injury by studying the relationship between the sciatic nerve and piriformis. DESIGN, TIME AND SETTING: Observe and measure repeatedly. The experiment was conducted in the Department of Anatomy, Tianjin Medical College between January and June 2005. MATERIALS: Fifty-two adult cadavers 33 males and 19 females, with a total of 104 hemispheres, and fixed with formaldehyde, were provided by Tianjin Medical College and Tianjin Medical University. METHODS: A posterior cut was made from the lumbosacral region to the upper leg, fully exposing the piriformis and path of the sciatic nerve. MAIN OUTCOME MEASURES: (1) Anatomical characteristics of the tibial nerve and common peroneal nerve. (2) According to different areas where the sciatic nerve crosses the piriformis, the study was divided into two types--normal and abnormal. Normal is considered to be when the sciatic nerve passes through the infrapiriform foramen. Remaining pathways are considered to be abnormal. (3) Observe the relationship between the suprapiriform foramen, infrapiriform foramen, as well as the superior and inferior space of piriformis. RESULTS: (1) The nerve tract inside the common peroneal nerve is smaller and thinner, with less connective tissue than the tibial nerve. When pathological changes or variations of the piriformis, or over-abduction of the hip joint, occur, injury to the common peroneal nerve often arises due to blockage and compression. (2) A total of 76 hemispheres (73.08%) were normal, 28 were abnormal (26.92%). The piriformis can be injured, and the sciatic nerve can become compressed, when the hip joint undergoes intorsion, extorsion, or abduction. (3) The structures between the infrapiriform and

    Full Text Available RESUMEN: Descripción geográfica del territorio de Santo Adriano, cuyos límites coinciden con los del municipio del mismo nombre, en las Asturias centrales: un valle fluvial con zonas de media montaña, perteneciente a la Zona Cantábrica, en el que abunda la "caliza de montaña". Los primeros indicios de poblamiento llegan hasta el paleolítico medio y superior con habitat en varias cuevas, de cuya época se conservan grabados en roca. Está configurado por un sistema de pequeños castros, con sus respectivos "espacios cástrales", que definen bien todo el territorio. La presencia de cultura romana es muy poco relevante. En la documentación medieval más antigua, finales del siglo X, sometida a notables interpolaciones "pelagianas", figuran ya los límites modernos del concejo, con pocas variantes. También se documenta la existencia de habitat troglodítico medieval por hallazgos de algunas, muy pocas, piezas cerámicas. El primer poblamiento altomedieval constaba de varias "villae", localizadas y descritas hasta donde es posible, donadas al monasterio-iglesia de Santo Adriano de Tuñón por Alfonso III yjimena (891. El monasterio fue fundado, asimismo, por estos soberanos, funcionando como el verdadero núcleo articulador de todo el poblamiento antiguo. Se trataba de un territorio vinculado al "Camín de la Mesa", un camino real prerromano, en uso hasta época moderna, que comunicaba Asturias con la meseta. Una localidad, Valdolayés, fue el escenario de una de las batallas más importantes de los astures contra el caudillo musulmán, Munuza, documentada en las Crónicas Asturianas.ABSTRACT: Geographic description of Santo Adriano territory, its frontiers are identical to the municipality with the same name, in Central Asturias: a river valley in mid mountain zones, in the Cantàbric Zone, where the limestone mountain is frequent.

    Full Text Available At the beginning of Delitto e perdono Adriano Prosperi recalls the killing of Osama Bin Laden, regarded as an act of justice by the American people and its president. Then, his book goes on spurring useful remarks about the history of the idea of conviction to death as a repair. One of the main threads of western thought about capital punishment can be found in contrasting vengeance and mercy from XI century, when Christ’s sacrifice became the ideal link for most criminal codes. In fact, every executed man could hope for God’s forgiveness and for his own soul’s salvation at the foot of the Cross. Face to the advices of Confortatori, which until XIX century escorted all men sentenced to death to the scaffold, almost none refused to agree to religious solace, and so the execution proceeding became a sacramental act.

    Full Text Available Peroneal artery arteriovenous fistulas and pseudoaneurysms are extremely rare with the majority of reported cases due to penetrating, orthopedic, or iatrogenic trauma. Failure to diagnose this unusual vascular pathology may lead to massive hemorrhage or limb threatening ischemia. We report an interesting case of a 14-year-old male who presented with acute musculoskeletal pain of his lower extremity. Initial radiographs were negative. Further imaging workup revealed a peroneal arteriovenous fistula with a large pseudoaneurysm. After initial endovascular intervention was unsuccessful, the vessels were surgically ligated in the operating room. Pathology revealed papillary endothelial hyperplasia consistent with an aneurysm and later genetic testing was consistent with Ehlers-Danlos syndrome Type IV. This case illustrates an unusual cause of acute atraumatic musculoskeletal pain and uncommon presentation of Ehlers-Danlos syndrome.

    Background Patients with chronic lateral ankle instability also have peroneal tendinopathy often. However, preoperative MRIs of these patients are vague in many cases. Our study was performed to see the reliability of MRI findings of peroneal tendinopathy in patients with chronic lateral ankle instability. Methods MRI images for 82 patients who had chronic lateral ankle instability, and had received surgical treatment between March 2006 and November 2009 were compared with impressions from operating rooms. The mean age of patients was 36.4 years (range, 15 to 64 years), 82 ankles were studied, and patients with rheumatoid diseases were excluded from the study. Results Of the 82 cases, 26 were true positives, 38 true negatives, 13 false positives and 5 false negatives. Of 39 cases of peroneal tendinopathy diagnosed from MRI, 14 had peroneal tendon partial tears, 15 tenosynovitis, 3 dislocations, 17 low-lying muscle bellies, and 6 peroneus quartus muscles. Of 31 cases of peroneal tendinopathy observed in surgery 11 had peroneal tendon partial tears, 4 tenosynovitis, 5 dislocations, 12 low-lying muscle belliess, and 1 peroneus quartus muscle. Sensitivity and specificity of peroneal tendinopathy were 83.9% and 74.5%, respectively. Positive predictive value was 66.7%. Negative predictive value was 88.4%. Accuracy rate was 78.0%. Conclusions MRI is a useful diagnostic tool for detecting peroneal tendinopathy in patients with chronic lateral ankle instability. However, MRI is vague in many cases. Therefore, a thorough delicate physical examination and careful observation is needed. PMID:21119941

    While cryotherapy has direct physiological effects on contractile tissues, the extent to which joint cooling affects the neuromuscular system is not well understood. The purpose of the study was to detect changes in ankle dynamic restraint (peroneal short latency response and muscle activity amplitude) during inversion perturbation following ankle joint cryotherapy. A 2x3 factorial design was used to compare reaction time and EMG amplitude data of treatment conditions (cryotherapy and control) across time (pre-treatment, post-treatment, and 30 min post-treatment). Thirteen healthy volunteers (age 23 ± 4 yrs, ht 1.76 ± 0.09 m, mass 78.8 ± 16.6 kg), with no history of lower extremity joint injury participated in this study. Surface EMG was collected from the peroneus longus (PL) of the dominant leg during an ankle inversion perturbation triggered while walking. Subjects walked the length of a 6.1 m runway 30 times. A trap door mechanism, inducing inversion perturbation, was released at heel contact during six randomly selected trials for each leg. Following baseline measurements, a 1.5 L bag of crushed ice was applied to the lateral ankle of subjects in the treatment group with an elastic wrap. A bag similar in weight and consistency was applied to the lateral ankle of subjects in the control group. A repeated measures ANOVA was used to compare treatment conditions across time (p 0.05) for PL reaction time. Average RMS EMG, normalized to an isometric reference position, increased in the cryotherapy group at the 30 min post-treatment interval relative to the control group (p movement is unknown.Short latency response should be measured during functional movement instead of during stance to take into consideration alterations in motor drive.Joint cooling has no effect on peroneal short latency response, and joint cooling may result in increased short term peroneal activation.Joint cooling has no effect on the peroneus longus as a dynamic stabilizer during walking.

    Superficial peroneal nerve and its branches are frequently at risk for iatrogenic damage. Although different studies on anatomical variations of superficial peroneal nerve are available in the medical literature, such reports are rare from India. Hence the present study was undertaken on Indian population. A total of 60 specimens of inferior extremities from 30 properly embalmed and formalin fixed cadavers were dissected and examined for the location and course of the superficial peroneal nerve including number, level, course and distributions of branches. The superficial peroneal nerve in 28.3% specimens was located in the anterior compartment of the leg. In 8.3% specimens the superficial peroneal nerve branched before piercing between the peroneus longus and extensor digitorum longus muscle whereas in 11.7% specimens it branched after piercing the aforementioned muscles and before piercing the deep fascia. In 41 out of 60 specimens the sensory division of superficial peroneal nerve branched into the medial dorsal cutaneous nerve and intermediate dorsal cutaneous nerve distal to its emergence from the deep fascia and proximal to its relation to the extensor retinaculum. In 20 out of 60 specimens the accessory deep peroneal nerve, an additional branch from the sensory division of superficial peroneal nerve, through its course in the anterior compartment of the leg passed deep to the extensor retinaculum and supplied the ankle and the dorsum of foot. Hopefully the present study will help in minimizing iatrogenic damage to the superficial peroneal nerve and its branches while performing arthroscopy, local anesthetic block, surgical approach to the fibula, open reduction and internal fixation of lateral malleolar fractures, application of external fixators, elevation of a fasciocutaneous or fibular flaps for grafting, surgical decompression of neurovascular structures, or miscellaneous surgery on leg, foot and ankle.

    A painful episode in the region of the peroneal tendons, within the retromalleolar groove, is a common precipitating event of an acute lateral ankle sprain. A forefoot striking pattern is suspected to cause peroneal tendinosis. The aim of this study is to analyse the role of peroneal tendinosis as a predisposing factor for ankle sprain trauma in runners. Fifty-eight runners who had experienced acute ankle sprain trauma, with pre-existing pain episodes for up to 4 weeks in the region of the peroneal tendons, were assessed clinically. Fractures were excluded by conventional radiography. An magnetic resonance imaging (MRI) scan had been performed within 14 days after the traumatic event and was subsequently evaluated by two experienced radiologists. MRI revealed peroneal tendinosis in 55 patients (95% of the total study population). Peroneus brevis (PB) tendinosis was found in 48 patients (87% of all patients with peroneal tendinosis), and peroneus longus (PL) tendinosis was observed in 42 cases (76%). Thirty-five patients (64%) had combined PB and PL tendinosis. A lesion of the anterior talofibular ligament was found to be the most common ligament injury associated with peroneal tendinosis (29 cases; 53%), followed by a lesion of the calcaneofibular ligament (16 cases; 29%) and a lesion of the posterior tibiofibular ligament (13 cases; 24%). The results of this study reflect the correlation between peroneal tendinosis and ankle sprain trauma. Injuries of one or more ligaments are associated with further complications. A period of rest or forbearance of sports as well as adequate treatment of the peroneal tendinosis is essential to prevent subsequent ankle injuries, especially in runners. Modification of the running technique would also be beneficial. IV.

    Full Text Available This article contributes to the understanding of the organizational structures of peronism, Argentine dominant political force, on the basis of a study on partisan appointments. It presents the main findings of a research on the scope, the workings, the motivations, and the criteria of partisan appointments in the Argentine state, with particular attention to Néstor Kirchner administration (2003-2007. The more general argument contends that appointments became in this period a crucial tool to control the state apparatus while, at the same time, they made it possible to renovate Peronist partisan elites under the leadership of the president. The data, obtained from a large series of expert interviews, make it possible to offer a new theoretical framework for the understanding of party-government linkages in contemporary Argentine democracy.

    The common peroneal nerve (CPN), a major terminal branch of the sciatic nerve, can be subject to a variety of pathologies, which may affect the nerve at any level from the lumbar plexus to its distal branches. Although the diagnosis of peripheral neuropathy is traditionally based on a patient's clinical findings and electrodiagnostic tests, magnetic resonance neurography (MRN) is gaining an increasing role in the definition of the type, site, and extent of peripheral nerve disorders. Current high-field MR scanners enable high-resolution and excellent soft-tissue contrast imaging of peripheral nerves. In the lower extremities, MR neurography has been employed in the demonstration of the anatomy and pathology of the CPN, as well as in the detection of associated secondary muscle denervation changes. This article reviews the normal appearance of the CPN as well as typical pathologies and abnormal findings at 3.0-T MR neurography of the lower extremity. (orig.)

    Full Text Available We describe entrapment of the common peroneal nerve by a suture after surgical repair of the distal biceps femoris tendon. Complete rupture of the distal biceps femoris tendon of a 16-year-old male athlete was surgically repaired. Postoperative common peroneal nerve palsy was evident, but conservative treatment did not cause any neurological improvement. Reexploration revealed that the common peroneal nerve was entrapped by the surgical suture. Complete removal of the suture and external neurolysis significantly improved the palsy. The common peroneal nerve is prone to damage as a result of its close proximity to the biceps femoris tendon and it should be identified during surgical repair of a ruptured distal biceps femoris tendon.

    The peroneal nerve is susceptible to traction injury during inversion ankle sprains. Previously, these traction lesions have been identified only at the fibular neck and popliteal fossa level. This report illustrates a previously unreported condition of perineural fibrosis of the superficial peroneal nerve at the level of the ankle following an inversion ankle sprain. Perineural fibrosis should be considered in the differential diagnosis of patients with persistent pain after ankle sprain.

    This anatomical study was carried out in order to discover the etiology of partial necrosis of the peroneus longus and brevis muscles after fibular osteocutaneous flap harvest. The vascular supply to the lateral compartment peroneal muscles was investigated in 10 fresh cadaveric lower limbs. The peroneal muscles are supplied by two principal sources arteries, the anterior tibial artery (ATA) and the peroneal artery (PA). The ATA is the dominant artery and supplies the proximal and middle thirds of these muscles. The PA is considered to be a supplementary vascular source and supplies the distal thirds of these muscles. After harvesting the PA in a fibular flap, regions of the peroneal muscles preoperatively vascularized by its branches become supplied through the anastomotic "choke" vessels between the ATA and the PA. Primary closure of the cutaneous defect increases the possibility of developing a pseudo-compartment syndrome with necrosis of the more precariously vascularized portions of the peroneal muscles. This complication is difficult to diagnosis early and the reason why we advocate that direct skin closure following composite harvest must be avoided. Moreover, conservation of the inferior and superior lateral branches of the ATA is imperative in order to preserve the peroneal muscles vascularization.

    The authors report the results of the dissection of the superficial peroneal nerves of 30 adult cadavers, from its emergence through the deep sural fascia up to its terminal branches. Its emergence was located, on average, 11 cm from the lower end of the lateral malleolus (min: 9 cm, max: 11.5 cm). The division of the nerve into the medial dorsal cutaneous n. and the intermediate dorsal cutaneous n. was found in 29 cases after its emergence from the sural fascia and before its passage on the proximal edge of the extensor retinaculum. The distance between the medial dorsal cutaneous n. and the medial malleolus was more than 2 cm. This nerve divided into three branches at a level varying from 5 to 20 cm in relation to the first interdigital space (average 9 cm). The intermediate dorsal cutaneous n. was found in 27 cases. It divided into two branches at a variable distance from the fourth interdigital space (4 to 6 cm). According to Kosinski's classification, we found 24 cases of type I (80%), three cases of type II (10%) and three cases of type IV (10%). The authors stress the numerous topographic variations and the multiple anatomical types.

  5. Use of superficial peroneal nerve graft for treating peripheral nerve injuries

    Full Text Available ABSTRACT OBJECTIVE: To evaluate the clinical results from treating chronic peripheral nerve injuries using the superficial peroneal nerve as a graft donor source. METHODS: This was a study on eleven patients with peripheral nerve injuries in the upper limbs that were treated with grafts from the sensitive branch of the superficial peroneal nerve. The mean time interval between the dates of the injury and surgery was 93 days. The ulnar nerve was injured in eight cases and the median nerve in six. There were three cases of injury to both nerves. In the surgery, a longitudinal incision was made on the anterolateral face of the ankle, thus viewing the superficial peroneal nerve, which was located anteriorly to the extensor digitorum longus muscle. Proximally, the deep fascia between the extensor digitorum longus and the peroneal longus muscles was dissected. Next, the motor branch of the short peroneal muscle (one of the branches of the superficial peroneal nerve was identified. The proximal limit of the sensitive branch was found at this point. RESULTS: The average space between the nerve stumps was 3.8 cm. The average length of the grafts was 16.44 cm. The number of segments used was two to four cables. In evaluating the recovery of sensitivity, 27.2% evolved to S2+, 54.5% to S3 and 18.1% to S3+. Regarding motor recovery, 72.7% presented grade 4 and 27.2% grade 3. There was no motor deficit in the donor area. A sensitive deficit in the lateral dorsal region of the ankle and the dorsal region of the foot was observed. None of the patients presented complaints in relation to walking. CONCLUSIONS: Use of the superficial peroneal nerve as a graft source for treating peripheral nerve injuries is safe and provides good clinical results similar to those from other nerve graft sources.

    In ankle arthroplasty, little attention has been given to intraoperative nerve injury and its postoperative sequelae. The aim of the present anatomic study was to determine the relationship of the superficial peroneal nerve to the standard anterior approach for total ankle arthroplasty. The superficial peroneal nerve was dissected in 10 below-the-knee cadaver specimens. The medial and intermediate dorsal cutaneous branches were identified. A needle was placed at the ankle joint. The following measurements were recorded: bifurcation into the medial and intermediate dorsal cutaneous branches, reference needle to the branches of the medial and intermediate superficial peroneal nerve, and the crossing branches of the medial dorsal cutaneous nerve. Two specimens (20%) had a medial dorsal cutaneous branch cross from medially to laterally. Eight specimens (80%) had a crossing branch of the medial dorsal cutaneous branch within 5 cm of the incision. No intermediate dorsal cutaneous branches were within the incision. The results from the present cadaver study suggest that during an anterior ankle approach, aberrant branches of the superficial peroneal nerve could require transection in 20% of patients at the joint level and ≤80% of patients with distal extension >35 mm from the ankle joint. The risk of injury to branches of the superficial peroneal nerve is substantial. The risk of nerve injury can be decreased with meticulous operative technique, smaller incisions, and the avoidance of aggressive retraction.

    This study analyzed imaging, arthroscopic findings, and treatment responses for peroneal spastic flatfoot (PSFF) caused by talocalcaneal impingement at the accessory anterolateral talar facet (AALTF) (accessory talar facet impingement) in 13 adolescents without histories of trauma and tarsal coalition. The AALTF was determined with computed tomography and MRI. Focal abutting bone marrow edema (FABME) on MRI around the AALTF was confirmed. In seven patients who underwent AALTF resection, subtalar arthroscopy was performed. All experienced alleviation PSFF after treatment; reduction in FABME was observed. AALTF resection alone is beneficial for PSFF caused by accessory talar facet impingement when peroneal spasms are restored by an injection of local anesthesia.

    The purpose of this case report is to describe a therapeutic intervention for peroneal nerve paralysis involving the sciatic nerve. A 24-year-old man presented with peroneal nerve paralysis with decreased sensation, severe pain in the popliteal fossa, and steppage gait, which occurred 3 days prior to the consultation. Magnetic resonance imaging and electromyography confirmed lumbar disk herniation with sciatic common peroneal nerve entrapment in the popliteal fossa. A combined treatment protocol of spinal and fibular head manipulation and neurodynamic mobilization including soft tissue work of the psoas and hamstring muscles was performed. Outcome measures were assessed at pretreatment, 1 week posttreatment, and 3-month follow-up and included numeric pain rating scale, range of motion, pressure pain threshold, and manual muscle testing. Treatment interventions were applied for 3 sessions over a period of 1 week. Results showed reduction of the patient's subjective pain and considerable improvement in range of motion, strength, and sensation in his left foot, which was restored to full function. A combined program of spinal and fibular head manipulation and neurodynamic mobilization reduced pain, increased range of motion and strength, and restored full function to the left leg in this patient who had severe functional impairment related to a compressed left common peroneal nerve.

    Full Text Available Aim: Trap neuropathy is characterized by compression of the peripheral nerve into fibro osseous channels in trespassing areas of body segments. Peroneal nerve is the most frequently injured nerve in traumatic injuries of the lower extremities. In the present study, we investigated functional results of surgical treatment of patients with peroneal nerve injury who delayed visiting our clinics after the damage; we also aimed to observe the effects of this delay on prognosis. We interpreted postoperative results of the patients with EMG and physical examination findings. Material and Method: Subjects with peroneal nerve damage who visited our clinics between 2012 and 2015 were included in the present study. EMG and muscle motor strength tests were conducted pre and postoperatively for clinical assessment. Results: Of the 16 patients in the study population, 7 were men and 9 were women. The median age of the subjects was 49.6 years (14-77 years. Admission time was 9 months after injury. Causes of the peroneal nerve damage were as follows: prosthesis surgery in 4 (25%, ankle damage in 2 (12.5%, excessive squatting by agriculture workers in 4 (25%, aggressive exercise in 2 (12.5%, bone fracture in 2 (12.5%, and unknown origin in 2 (12.5%. Discussion: Peroneal nerve injury usually occurs by compression of the nerve at the head or neck of the fibula. Results of decompression surgery are usually compromising in non-traumatic nerve palsies. Period of duration between injury and diagnosis and muscular atrophy are main factors associated with success of treatment.

    Background Sural neurofasciocutaneous flap has been popularly used as an excellent option for the coverage of soft tissue defects in the lower third of leg, ankle and foot, but its free transplantation has been rarely reported. The objective of our work was to investigate the operative technique and clinical results of repairing the soft tissue defects of hand and forearm with free peroneal perforator-based sural neurofasciocutaneous flap. Methods Between May 2006 and March 2007, 10 patients including 7 men and 3 women were treated. Their ages ranged from 22 to 51 years. They presented to emergency with large soft tissue defects of 16 cm × 7 cm to 24 cm × 10 cm in size in hand and forearm after injured by motor vehicle accidents (2 cases) or crushed by machine (8 cases). Thorough debridements and primary treatments to associated tendon ruptures or bone fractures were performed on emergency. And free peroneal perforator-based sural neurofasciocutaneous flaps were transplanted when the wound areas were stable at 5 to 7 days after emergency treatment. The flaps were designed along the axis of the sural nerve according to the shape and size of the soft tissue defects, with the peroneal perforator above the lateral malleolus as the pedicle and along with a part of the peroneal artery for vascular anastomosis. Then the flaps were harvested to repair the recipient sites with the pereneal artery anastomosed to the radial (or ulnar) artery and the peroneal veins to one of the radial (or ulnar) veins and the cephalic vein respectively. The flap sizes ranged from 18 cm × 8 cm to 25 cm × 12 cm. The donor areas were closed by skin grafts. Results All of the 10 flaps survived after surgeries. Marginal necrosis occurred in only 2 cases. The skin grafts survived entirely in the donor sites, and no obvious influence on the donor legs was observed. All of the transplanted flaps presented favourable contours and good functions at 9 to 12 months' follow-up. Conclusions Peroneal

    The 'SAFARI' technique or subintimal arterial flossing with antegrade-retrograde intervention is a method for recanalisation of chronic total occlusions (CTOs) when subintimal angioplasty fails. Retrograde access is usually obtained via the popliteal, distal anterior tibial artery (ATA)/dorsalis pedis (DP), or distal posterior tibial artery (PTA). Distal access via the peroneal artery has not been described and has a risk of continued bleeding, leading to compartment syndrome due to its deep location. We describe our experience in two patients with retrograde access via the peroneal artery and the use of balloon-assisted hemostasis for these retrograde punctures. This approach may potentially give more options for endovascular interventions in lower limb CTOs.

One option in this region is the pedicled fasciocutaneous flap based on perforators of the peroneal artery. In this case series, we present our experience of the peroneal island pedicled flap for reconstruction of lower extremity wounds.Methods: Records of 18 cases of peroneal island flap admitted consecutively to the Section of Orthopedics at Aga Khan University Hospital from January 1996 to December of 2009 were studied and their outcomes determined.Results: The most common indication for coverage was open wounds due to a road traffic accident (n = 10, followed by burns (n = 3. The most common area exposed was the lower third of the leg followed by the middle third. The tibia was exposed in 11 patients. The flaps ranged in size from 35 cm2 to over 200 cm2. In 13 patients, the flaps healed uneventfully, while in the remaining five there was partial flap necrosis. In four of the latter patients, the residual wound healed with conservative measures only, but the fifth patient required further surgery to achieve acceptable coverage.Conclusion: The peroneal artery flap appears to be a simple, useful, and reliable flap in the armamentarium of the surgeon when planning soft tissue coverage of the lower extremity.Keywords: leg injuries, surgical flaps, lower extremity

    Objective. Electrical stimulation has been shown effective in restoring basic lower extremity motor function in individuals with paralysis. We tested the hypothesis that a flat interface nerve electrode (FINE) placed around the human tibial or common peroneal nerve above the knee can selectively activate each of the most important muscles these nerves innervate for use in a neuroprosthesis to control ankle motion. Approach. During intraoperative trials involving three subjects, an eight-contact FINE was placed around the tibial and/or common peroneal nerve, proximal to the popliteal fossa. The FINE's ability to selectively recruit muscles innervated by these nerves was assessed. Data were used to estimate the potential to restore active plantarflexion or dorsiflexion while balancing inversion and eversion using a biomechanical simulation. Main results. With minimal spillover to non-targets, at least three of the four targets in the tibial nerve, including two of the three muscles constituting the triceps surae, were independently and selectively recruited in all subjects. As acceptable levels of spillover increased, recruitment of the target muscles increased. Selective activation of muscles innervated by the peroneal nerve was more challenging. Significance. Estimated joint moments suggest that plantarflexion sufficient for propulsion during stance phase of gait and dorsiflexion sufficient to prevent foot drop during swing can be achieved, accompanied by a small but tolerable inversion or eversion moment.

    Low-lying peroneus brevis tendon muscle belly has been speculated to be an associated factor with symptomatic peroneal tendon pathology. Multiple studies have analyzed normal and anomalous anatomy associated with peroneal tendon pathology; however, no study has confirmed the clinical association between peroneal tendon pathology and low-lying peroneus brevis muscle belly. To identify the correlation of low-lying peroneus brevis muscle belly with peroneal tendon pathology. Case-control study; Level of evidence 3. The level of peroneus brevis muscle belly was compared between patients with symptomatic peroneal tendon pathology (experimental group) and asymptomatic individuals with otherwise normal lateral ankle using magnetic resonance images. Of the 32 consecutive patients with symptomatic peroneal tendon pathology, 28 (87.5%) demonstrated peroneus brevis muscle distal to the fibular groove while 53.8% of control patients demonstrated such findings (P = .022). The most common diagnosis associated with peroneal tendon pathology was ankle instability and osteochondral defect of the talus or tibial plafond. Peroneal tendon pathology in isolation was less common. Peroneal tendon pathology is often associated with lateral ankle instability and osteochondral defects of the ankle joint. Low-lying peroneus brevis muscle belly may be a common anatomic variant, but in the setting of instability it can become a source of pain and pathology secondary to overcrowding.

    The aim of this case report is to present an unusual double synovial cyst that arose from the proximal tibiofibular joint compressing the peroneal nerve in the peroneal tunnel and was unrecognized at the beginning. According to the review of literature back to 1891, only 62 cases of cysts originating from the proximal tibiofibular joint (PTFJ) have been described. We report a case of a 32 year old male patient who was admitted to the Department of Orthopaedic Surgery because of a classic peroneal tunnel syndrome of the left leg. On the lateral side of the proximal third of his left leg a tumefaction of 12 x 2.5 cm was visible. The sonography showed a characteristic image of the para-articular synovial cyst of the left knee. A surgical extirpation of the synovial cyst and decompression of the peroneal nerve in the peroneal tunnel were performed. PHD confirmed a classic synovial cyst. Postoperatively, the symptoms of the peroneal nerve compression disappeared. Three years after the first surgical intervention the patient was readmitted to the Department because of quite similar problems, only the neurological symptoms were less intensive than during the first admittance. This time the performed MR imaging showed a double synovial cyst originating from the proximal tibiofibular joint. The surgical treatment consisted of a total extirpation of both cysts including the narrow stalks of communication with the PTFJ. The joint was opened and a synovectomy was done using an electrocauter and a sharp curette. Regular check-ups were done every 6 months and twice during the control period of 4 years, as was the MR imaging control. MRI findings 4 years after the second surgical intervention were normal. Clinical findings after 7 years were normal and we are sure that the recidivation of the synovial cyst excluded. The MRI diagnostics was crucial for an adequate surgical treatment and the relief of the peroneal tunnel syndrome symptoms.

    We present a patient who developed a peroneal intraneural ganglion and an adventitial cyst following the incomplete treatment of a tibial intraneural ganglion. These separate cysts all originated from the superior tibiofibular joint and dissected along their respective articular branches. A logical mechanistic explanation for these coexisting cysts is provided, which highlights the shared pathogenesis - its joint-related nature - rather than a multifocal de novo process. These observations would not only be consistent with, but would extend previous evidence in support of, the unifying articular (synovial) theory. (orig.)

    1999-09-01

    We reviewed eight patients who sustained superficial peroneal nerve neuralgia after an inversion ankle sprain. Surgical exploration found anatomic abnormalities that tethered the nerve from movement during plantarflexion and inversion of the ankle. Most patients' pain improved dramatically after release and anterior transposition of the nerve. Seven joints also underwent arthroscopy, which showed intra-articular disease that was consistent with the original trauma. Five patients had reflex sympathetic dystrophy, three of which resolved after nerve release. Nerve conduction studies were not helpful. Careful physical examination and local nerve blocks were most important in making the diagnosis and prescribing treatment. All conservative measures should be exhausted before surgery is considered.

    Lesions of the distal arteries of the leg are of similar frequency and importance as proximal lesions. Most frequently distal and proximal lesions are present. When distal intraoperative arteriography is carried out before a femoropopliteal by-pass, 68% of cases have associated distal lesions. When the popliteal artery is occluded, the by-pass must extend to the tibio-peroneal trunk, a tibial artery or the peroneal artery. In this paper 79 of these distal by-passes are reported, together with the results. Although there are arterial lesions limited to the ankle, it is not frequent to find this type of pathology. Of 900 patients with occlusive disease treated surgically, we only found 35 such cases (3.9%). However, the presence of this lesion may endanger the function and the integrity of the limb. This paper describes the clinical picture and pathology of the disease process, as well as the treatment by short venous by-pass at the ankle.

    Full Text Available Background: Large soft tissue defects around the lower third of the leg, ankle and foot always have been challenging to reconstruct. Reverse sural flaps have been used for this problem with variable success. Free tissue transfer has revolutionised management of these problem wounds in selected cases. Materials and Methods: Twenty-two patients with large defects around the lower third of the leg, ankle and foot underwent reconstruction with reverse peroneal artery flap (RPAF over a period of 7 years. The mean age of these patients was 41.2 years. Results: Of the 22 flaps, 21 showed complete survival without even marginal necrosis. One flap failed, where atherosclerotic occlusion of peroneal artery was evident on the table. Few patients had minor donor site problems that settled with conservative management. Conclusions: RPAF is a very reliable flap for the coverage of large soft tissue defects of the heel, sole and dorsum of foot. This flap adds versatility in planning and execution of this extended reverse sural flap.

    This study aimed to clinically evaluate the results achieved by using tendon transposition to treat postinjection peroneal paralysis in calves. The study material consisted of 23 calves in all of which the clinical history indicated the problem had occurred within 1-3 days of intramuscular injection. Each patient was administered medical treatment for three weeks. After that, a decision was made to perform tendon transposition in all the subjects because their prognosis was estimated to be poor. The owners of five of the calves did not agree to the operation, and so, medical treatment was continued. Following intrathecal anaesthesia, the vastus lateralis muscle was dissected at the insertion, and the musculus (m) extensor (ext) digitalis (dig) longus and m fibularis tertius were dissected at the origin in 18 calves. The tendon ends were joined by using the locking loop suture technique in the 18 calves. Follow-up after two to three months revealed hind limb use in all surgically treated calves, while the medically treated calves had to be slaughtered because of lameness and decubitus. The results of the present study suggest that the peroneal paralysis of calves can be successfully treated by a tendon transposition technique.

    Posterior antiglide plating is widely used to treat lateral malleolar fractures caused by supination-external rotation injuries. Despite its widespread use, this technique can be associated with postoperative peroneal tendinopathy. The purpose of the present observational review was to report the incidence of peroneal tendinopathy after the use of posterior antiglide plating to treat lateral malleolar fractures caused by a supination-external rotation injury. A total of 70 patients were followed up for a minimum of 12 (mean 55, range 12 to 109) months. Bony union was obtained in all cases after a mean of 57 (range 37 to 81) days. The median number of screw holes in the plate was 4.9 (range 4 to 7), and the median number of screws used to fixate the fibula was 6.58 (range 5 to 10). The mean American Orthopaedic Foot and Ankle Society hindfoot-ankle score at the final follow-up examination was 90.8 (range 55 to 100). Clinically, 3 (4.29%) of the 70 patients had lateral or posterolateral ankle pain indicative of peroneal tendinopathy after the index surgery, without any objective evidence. Of the 70 patients, 41 (58.57%) underwent surgical removal of the fibular hardware, 2 (4.87%) because of lateral ankle discomfort. At removal, inspection of the peroneal tendon sheath and/or tendons showed no gross evidence of tendinopathy in any of the patients. We concluded that the incidence of clinically evident peroneal tendon symptoms associated with posterior antiglide plating is low (4.3%), and direct operative inspection revealed no gross evidence of tendinopathy.

    2014-01-01

    Full Text Available MR microneurography is a noninvasive technique that provides visualization of the microanatomy of peripheral nerves, otherwise available only with histopathology. The objective of this study was to present a protocol to visualize the microstructure of peripheral nerves in vivo, using a 3T MRI scanner with a clinical set of coils and sequences. The tibial and the common peroneal nerves of healthy volunteers were imaged above the medial malleolus and at the level of the fibular head, respectively. The acquired images provided details about the internal structure of peripheral nerves, with visualization of the fascicles, the interfascicular fat, the epineurium, and the perineurium. MR microneurography can be performed in a clinical setting with acceptable imaging times and can be a potentially powerful tool that complements standard MR neurography.

    2006-06-01

    Correction of drop foot in hemiplegic gait is achieved by electrical stimulation of the common peroneal nerve with a series of pulses at a fixed frequency. However, during normal gait, the electromyographic signals from the tibialis anterior muscle indicate that muscle force is not constant but varies during the swing phase. The application of double pulses for the correction of drop foot may enhance the gait by generating greater torque at the ankle and thereby increase the efficiency of the stimulation with reduced fatigue. A flexible controller has been designed around the Odstock Drop Foot Stimulator to deliver different profiles of pulses implementing doublets and optimum series. A peripheral interface controller (PIC) microcontroller with some external circuits has been designed and tested to accommodate six profiles. Preliminary results of the measurements from a normal subject seated in a multi-moment chair (an isometric torque measurement device) indicate that profiles containing doublets and optimum spaced pulses look favourable for clinical use.

    Norihiko Kawaguchi

    2012-10-01

    Full Text Available Hereditary neuropathy with liability to pressure palsy (HNPP is characterized by recurrent focal neuropathies, which usually become symptomatic in the second or third decade of life. However, clinical phenotypic heterogeneity among patients with HNPP has recently been reported. Certain patients show polyneuropathy-type diffuse nerve injuries, whereas others remain asymptomatic at older ages. We present two cases of elderly-onset bilateral peroneal nerve palsies with diffuse muscle weakness in the lower limbs and glove-and-stocking type sensory disturbance. Both patients were diagnosed with HNPP by genetic analyses that detected deletions of chromosome 17p11.2 in peripheral myelin protein 22 genes. Their clinical courses suggested that the Japanese sitting style termed ‘seiza’, a way of sitting on the floor with the lower legs crossed under the thighs, was a precipitating factor for the bilateral peroneal nerve palsies.

    BACKGROUND: Peroneal muscular atrophy (PMA) is characterized by insidious onset, gradually progressive course of disease, very mild disability degree and easily subjecting to missed diagnosis and misdiagnosis.Nerve conductive velocity is helpful in the diagnosis of atypical cases.OBJECTIVE: To retrospectively analyze the characteristics of clinical manifestation, electromyogram (EMG),motor and sensory nerve conduction velocity of patients with PMA.DESIGN: Retrospective case analysis.SETTING: Department of Neurology, Guangzhou First People's Hospital.PARTICIPANTS: Twenty-four patients with PMA, including 16 males and 8 females, aged 5-68 years old,admitted to Guangzhou First People's Hospital between March 1996 and January 2006 were recruited.Informed consents were obtained from all the patients.METHODS: All the patients subjected to EMG and detection of nerve conduction velocity at distal end of four extremities with a Keypoint evoked potential/ EMG instrument (Denmark). Sensory and motor conduction velocity, EMG changes of upper and lower extremities were observed, and relationship of neuroelectrophysiological characteristics and clinical symptoms was analyzed.MAIN OUTCOME MEASURES: Changes in sensory and motor conduction velocity, EMG and clinical manifestations of 24 patients.RESULTS: ① All the patients suffered from insidious onset and gradually progressive course of PMA.Muscular atrophy of lower extremity was found in 14 patients, and that of upper extremity in 5 patients. ② Routine nerve conduction study showed that sensory and motor conduction velocity were stepped down,especially in 16 patients with type Ⅰ PMA (demyelinating pattern, nerve conduction velocity below normal level 50%). Motor nerve conduction velocity of median nerve, ulnar nerve, common peroneal nerve and tibial nerve averaged 34.8 m/s, 37.2 m/s, 16.5 m/s and 17.4 m/s, respectively; Sensory nerve conduction velocity of median nerve, ulnar nerve and sural nerve averaged 27.9%, 24.6 m

    2016-04-01

    Foot drop is a complex symptom with a considerable range in aetiology, severity and prognosis. We aim to characterise the aetiologies of foot drop and assess the diagnostic contribution of neurophysiologic testing (NCS\\/EMG). Retrospective review of consecutive referrals of foot drop to the Neurophysiology Department in Cork University Hospital was performed over a two year period (January 2012 to December 2013). Of a total of 59 referrals, common peroneal nerve (CPN) palsy comprised only slightly more than half of cases; 3(5%) have central origin; 3(5%) have motor neuron disease. Six (10%) have diabetes; 7(12%) have cancer; 5(8%) were bilateral. NCS\\/EMG altered initial working diagnosis in 14 out of 52 (27%) cases whereby initial diagnosis was provided. However one-third of all cases revealed additional coexistent pathology in an anatomic location remote to that of the primary diagnosis. Foot drop with central and proximal localisations are important and under recognised. NCS\\/EMG is valuable and also reveals additional pathology which warrants investigation

    2017-01-01

    To investigate the efficacy of kinesiology taping in mediating the influence of fatigue on ankle sprain risk, 12 male soccer players completed single-leg dynamic balance trials pre- and post-exercise (soccer-specific protocol, isokinetic ankle inversion/eversion protocol) in each of three counter-balanced taping conditions (no tape, zinc oxide tape ZO, kinesiology tape KT). Balance was quantified as the overall stability index (OSI) and directional stability indices of platform deflection. Soccer-specific fatigue only increased OSI in the no tape condition (p = 0.03), with ZO and KT trials negating a fatigue affect. Localized fatigue increased OSI in the no tape (p = 0.01) and ZO (p = 0.05) trials, with no increase in the KT trial. A similar pattern was observed in medio-lateral and anterio-posterior balance indices. KT mediates soccer-simulated and local peroneal fatigue, with practical implications for epidemiological observations of increased injury risk during the latter stages of match play.

  11. The accessory peroneal (fibular) muscles: peroneus quartus and peroneus digiti quinti. A systematic review and meta-analysis.

    The denomination of "accessory peroneal muscle" (APM) refers usually to two muscles: the peroneus quartus (PQua) and the peroneus digit quinti (PQui) which were believed to be variants of a same muscle. Their morphology and prevalence show high variation in relevant literature mainly owing to the diverse terminology used to describe this muscle group. The aim of this meta-analysis is to generate more accurate description and frequency of those muscles. A total of 46 studies (3,928 legs/ankles) met the inclusion criteria. The aggregate results were: (a) a true APM prevalence of 16 % with 10.2 % for PQua vs. 34.3 % for PQui; (b) a crude prevalence of 16.6 % for PQua vs. 21.5 % for PQui; (c) a bilateral prevalence of 1.73 % for PQua vs. 12.5 % for PQui; (d) the PQua was significantly more prevalent in Indian populations compared to all other ancestries, and the PQui is significantly more prevalent in Europeans and Americans compared to Japanese and Korean populations; (e) though a tendency for higher frequency was found in males and on the right specimens, no significance was found for gender and side; for (f) the "surgical" occurrence of PQua in studies dealing with peroneal tendon surgery was 5.5 % where peroneal tendon pathology seems to be not associated with the presence of an APM; (g) the MRI prevalence of APM was 10.6 %; (h) APMs took origin from peroneus brevis in 60 %, from the distal fibula in 36 % and from other structures in 4 %; (i) APMs took insertion on retrotroclear eminence of the calcaneum in 53.4 %, on peroneal trochlea in 6.6 %, merged with a peroneal tendon in 9.3 %, and inserted on the extensor apparatus of the 5th toe in 18.4 %. Despite the acknowledged limitation owing to the varied terminology used to describe this accessory muscle group, the significant differences found between the aggregate frequency estimates of each muscle do not support the hypothesis that both muscles are variants of a same structure.

    The aim of this article is to report on three patients with injuries of the peroneal nerve along the posterolateral aspect of the knee. Injuries in this area are less common than the injuries occurring at the level of the fibular head. In this article we report on three patients with posterolateral knee trauma who had peroneal nerve dysfunction. To better understand the precise location of the nerve on MR images, we performed MR imaging in five volunteers, and studied the position of the nerve on anatomic dissection (n=1) and anatomic slices (n=1). The common peroneal nerve is easily depicted on MR images and has a typical location along the posterior margin of the biceps tendon. Non-visualisation of the peroneal nerve at the posterolateral aspect of the knee, as seen on MR images, is consistent with nerve injury. Scar tissue at the posterolateral aspect of the knee indicates injury of this specific area, and involvement of the peroneal nerve is likely. (orig.)

    To determine the proportion of (1) peroneal tendon displacement (PTD) and posteromedial structure entrapment (PMSE) cases in a sample of pilon fractures, (2) missed diagnoses of PTD and PMSE on computed tomography (CT) by radiologists and attending orthopaedic trauma surgeons, and PTD and PMSE cases by (3) OTA/AO classification, and (4) fibular fracture. Retrospective cohort review. Regional level 1 Trauma Center. Two hundred patients treated between July 2008 and November 2014. Axial and reconstructed CT images were used in bone and soft tissue windows to identify PTD and PMSE. Medical charts were reviewed to identify OTA/AO fracture classification, the presence of concomitant fibular fracture, whether radiologist CT interpretation noted PTD or PMSE, and whether attending orthopaedic trauma surgeons' operative notes mentioned recognition of and management of PTD or PMSE. From the retrospective review of CT, PTD was identified in 11.0% and PMSE in 19.0% of all pilon fractures. Of the 22 patients with PTD, 59.1% sustained a concomitant fibular fracture and 90.9% sustained a 43-C fracture. Patients with PTD sustained more 43-C fractures (90.9% vs. 62.9%) but significantly fewer fibular fractures (59.1% vs. 80.3%; P = 0.023) than patients without PTD. Of the 38 patients with PMSE, 81.6% sustained a fibular fracture and 86.8% sustained a 43-C fracture. PMSE was more common in patients with 43-C fractures (86.8% vs. 61.1%). The final preoperative radiologist CT interpretation commented on PTD and PMSE in 50.0% of cases. Higher energy pilon fractures (43-C) are associated with higher incidence of PMSE and PTD. Concomitant fibula fracture may play a protective role in PTD in the setting of pilon fractures. Both attending radiologists and attending orthopaedic trauma surgeons frequently fail to recognize the diagnoses of PTD and PMSE. Prognostic level III.

    OBJECT Knee dislocations are often accompanied by stretch injuries to the common peroneal nerve (CPN). A small subset of these injuries also affect the tibial nerve. The mechanism of this combined pattern could be a single longitudinal stretch injury of the CPN extending to the sciatic bifurcation (and tibial division) or separate injuries of both the CPN and tibial nerve, either at the level of the tibiofemoral joint or distally at the soleal sling and fibular neck. The authors reviewed cases involving patients with knee dislocations with CPN and tibial nerve injuries to determine the localization of the combined injury and correlation between degree of MRI appearance and clinical severity of nerve injury. METHODS Three groups of cases were reviewed. Group 1 consisted of knee dislocations with clinical evidence of nerve injury (n = 28, including 19 cases of complete CPN injury); Group 2 consisted of knee dislocations without clinical evidence of nerve injury (n = 19); and Group 3 consisted of cases of minor knee trauma but without knee dislocation (n = 14). All patients had an MRI study of the knee performed within 3 months of injury. MRI appearance of tibial and common peroneal nerve injury was scored by 2 independent radiologists in 3 zones (Zone I, sciatic bifurcation; Zone II, knee joint; and Zone III, soleal sling and fibular neck) on a severity scale of 1-4. Injury signal was scored as diffuse or focal for each nerve in each of the 3 zones. A clinical score was also calculated based on Medical Research Council scores for strength in the tibial and peroneal nerve distributions, combined with electrophysiological data, when available, and correlated with the MRI injury score. RESULTS Nearly all of the nerve segments visualized in Groups 1 and 2 demonstrated some degree of injury on MRI (95%), compared with 12% of nerve segments in Group 3. MRI nerve injury scores were significantly more severe in Group 1 relative to Group 2 (2.06 vs 1.24, p knee dislocations

    Peroneal spastic flatfoot is an uncommon condition. It often presents as a rigid and usually painful valgus deformity in the hindfoot with peroneal muscles spasms. Although tarsal coalition is an important cause, a few patients have not undergone bone coalitions. We describe a 27-year-old female who experienced recurrent peroneal spastic flatfoot after an injury. She was treated successfully with a combination of botulinum toxin type A and immobilization of the foot in a neutral position with a cast. After 3 years, the condition had not recurred, and she was pain free and walked normally, with no increase in muscle tone. This unique treatment could be of potential use to treat many patients with such conditions.

    Ankle fractures are a significant part of the lower extremity trauma seen in the emergency department. Neurologic complications of ankle fracture surgery are infrequently described but account for significant morbidity. The risk of nerve injury is increased for the Blair and Botte type B pattern of the intermediate cutaneous dorsal nerve branch, crossing the distal fibula from posterior to anterior (at 5 to 7 cm from malleolar tip). This pattern is present in about 10% to 15% of patients. Injuries to the superficial peroneal nerve and its branches negatively influence the outcome. Early recognition and protection might reduce the incidence of superficial peroneal nerve injuries during open reduction and internal fixation of lateral malleolus fractures. We describe 2 surgically treated ankle fractures with superficial peroneal nerve branch (intermediate cutaneous dorsal nerve) involvement and review the current literature.

    Objective.  To assess the orthotic effect of a functional electrical stimulation device (Akita Heel Sensor System; AHSS) in the treatment of hemiplegic gait with foot drop. Materials and Methods.  In the AHSS, a heel sensor is attached to a small plastic heel brace, and the peroneal nerve is stimulated via percutaneous intramuscular electrodes. During the swing phase of the hemiplegic gait, the common peroneal nerve is stimulated by the AHSS. Eight patients in chronic stages of hemiplegia participated in this study. Walking speeds and step cadences on a 10-m course were compared between walking with stimulation and walking without stimulation. Results.  Mean walking speed (± SD) was 0.50 ± 0.26 m/sec without stimulation and 0.64 ± 0.31 m/sec with stimulation. The mean percentage increase in walking speed with stimulation was 30.1%. Mean step cadence was 31 ± 7 steps/10 m without stimulation and 27 ± 7 steps/10 m with stimulation. By correcting foot drop, the AHSS significantly increased walking speed and decreased cadence (p AHSS can significantly improve walking in hemiplegic patients with foot drop.

    Full Text Available Nerve crush injury is a well-established axonotmetic model in experimental regeneration studies to investigate the impact of various pharmacological treatments. Hericium erinaceus is a temperate mushroom but is now being cultivated in tropical Malaysia. In this study, we investigated the activity of aqueous extract of H. erinaceus fresh fruiting bodies in promoting functional recovery following an axonotmetic peroneal nerve injury in adult female Sprague-Dawley rats by daily oral administration. The aim was to investigate the possible use of this mushroom in the treatment of injured nerve. Functional recovery was assessed in behavioral experiment by walking track analysis. Peroneal functional index (PFI was determined before surgery and after surgery as rats showed signs of recovery. Histological examinations were performed on peroneal nerve by immunofluorescence staining and neuromuscular junction by combined silver-cholinesterase stain. Analysis of PFI indicated that return of hind limb function occurred earlier in rats of aqueous extract or mecobalamin (positive control group compared to negative control group. Regeneration of axons and reinnervation of motor endplates in extensor digitorum longus muscle in rats of aqueous extract or mecobalamin group developed better than in negative control group. These data suggest that daily oral administration of aqueous extract of H. erinaceus fresh fruiting bodies could promote the regeneration of injured rat peroneal nerve in the early stage of recovery.

    Drop foot is typically caused by neurologic disease such as lumbar disc herniation, but we report two rare cases of deep peroneal nerve palsy with isolated lateral compartment syndrome secondary to peroneus longus tears. Both patients developed mild pain in the lower legs while playing sport, and were aware of drop foot. As compartment pressures were elevated, fasciotomy was performed immediately, and the tendon of the peroneus longus was completely detached from its proximal origin. The patients were able to return their original sports after 3 months, and clinical examination revealed no hypesthesia or muscle weakness in the deep peroneal nerve area at the time of last follow-up. The common peroneal nerve pierced the deep fascia and lay over the fibular neck, which formed the floor of a short tunnel (the so-called fibular tunnel), then passed the lateral compartment just behind the peroneus longus. The characteristic anatomical situation between the fibular tunnel and peroneus longus might have caused deep peroneal nerve palsy in these two cases after hematoma adjacent to the fibular tunnel increased lateral compartment pressure.

    2015-06-01

    Full Text Available This article deals with the international dimension of Argentine domestic policies by exploring one of the strategies of the conservative daily newspaper La Nación, between 1946 and 1950, in order to challenge Juan Perón’s hegemony. La Nación presented the Peronist regime as akin to the totalitarian regimes established under the Soviet Union’s vigilance. This is not surprising, but revealing the complex ideological mechanisms employed by La Nación in its strategy is a noteworthy endeavor. This work will provide a thorough exploration of the process through which La Nación shifted from its former opposition to Peronism, initially identified as a Nazi-Fascist movement, to a new articulation of the regime as a totalitarian one. To some extent this was not so different from the strategy that the United States’ (US intellectual elites were carrying out in order to justify their struggle against a former ally in war as a continuation of purpose and not a rupture. Yet, the most interesting aspect of this evolution in the Argentine case is that it emerged in an autonomous way as a result of specific national and international phenomena. This shows that the characteristics of the early phase of the Cold War were shaped by transnational processes of convergence rather than US hegemony alone.Este artículo analiza la dimensión internacional de la política interna argentina explorando la estrategia del diario conservador La Nación, entre 1946 y 1950 en su enfrentamiento con el gobierno de Juan Domingo Perón.

Esto no resulta sorprendente, pero comprender los complejos mecanismos ideológicos empleados por La Nación en esta estrategia es un objetivo relevante de investigación.

    High-resolution ultrasonography (HRUS) is an emerging new tool in the investigation of peripheral nerves. We set out to assess the utility of HRUS performed at lower extremity nerves in peripheral neuropathies. Nerves of 26 patients with polyneuropathies of different etiologies and 26 controls were investigated using HRUS. Patients underwent clinical, laboratory, electrophysiological assessment, and a diagnostic sural nerve biopsy as part of the routine work-up. HRUS was performed at the sural, tibial, and the common, superficial, and deep peroneal nerves. The superficial peroneal nerve longitudinal diameter (LD) distinguished best between the groups: patients with immune-mediated neuropathies (n = 13, including six with histology-proven vasculitic neuropathy) had larger LD compared to patients with non-immune-mediated neuropathies (p neuropathies.

    Beller, Benjamin J.

    Remote sensing data, dendrochronology, Geographical Information Systems (GIS), and anecdotal information were used to describe the fire regime of the 180,000 ha Peron Peninsula of Western Australia. Fire scars present in 1944 aerial photos were still visible in 2009, both in imagery and on the ground. Tree-ring dates from specimens sampled within these burned areas indicated the occurrence of at least three separate fires before 1944. The oldest fire occurred ca. 1911 and burned at least 5,880 ha. Subsequent fires ca. 1922 and 1936 burned across 8,240 ha and 9,400 ha respectively. The fire dates determined from tree-ring counts were consistent with precipitation data which showed conditions particularly favorable for fire before or during the estimated year of each fire. Plant communities most often burned before 1944 were the Acacia ramulosa var. linophylla Scrub and the Acacia - Lamarchea hakefolia Thicket with, respectively, 73% and 75% of these plant community types at the study area found to have been burned at some time. Remote sensing imagery from 1944-2009 identified only 300 additional hectares burned, a 25 ha fire in 1991 in the combined Acacia ramulosa var. linophylla Scrub and A.ligulata and A. rostellifora Thicket, ten prescribed burns in 1995 totaling 274 ha in various habitats, and two late 1990's scars from prescribed burns designed to create fire buffers, one 4.6 km and the other 7.4 km long. Combined data for all years assessed showed 59,000 ha (66%) of the total study area to have been burned or reburned since ca. 1911, most prior to 1944, with a total of nearly 24,000 ha (27%) of the study area unburned for more than 110 years. Birridas, which cannot burn, accounted for the remaining 6,000 ha (7%) of the study area. These results show fire occurred more frequently 100 years ago (fires every 10-15 years) than at present (> 65 years between fires) suggesting that more frequent prescribed burning than occurs at present on the Peron Peninsula would

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

    Full Text Available INTRODUCTION: This study evaluated the degree of disability, pain levels, muscle strength, and electromyographic function (RMS in individuals with leprosy. METHODS: We assessed 29 individuals with leprosy showing common peroneal nerve damage and grade 1 or 2 disability who were referred for physiotherapeutic treatment, as well as a control group of 19 healthy participants without leprosy. All subjects underwent analyses of degree of disability, electromyographic tests, voluntary muscle force, and the Visual Analog Pain Scale. RESULTS: McNemar's test found higher levels of grade 2 of disability (Δ = 75.9%; p = 0.0001 among individuals with leprosy. The Mann-Whitney test showed greater pain levels (Δ = 5.0; p = 0.0001 in patients with leprosy who had less extension strength in the right and left extensor hallucis longus muscles (Δ = 1.28, p = 0.0001; Δ = 1.55, p = 0.0001, respectively and dorsiflexion of the right and left feet (Δ = 1.24, p = 0.0001; Δ = 1.45, p = 0.0001, respectively than control subjects. The Kruskal-Wallis test showed that the RMS score for dorsiflexion of the right (Δ = 181.66 m·s-2, p = 0.001 and left (Δ = 102.57m·s-2, p = 0.002 feet was lower in patients with leprosy than in control subjects, but intragroup comparisons showed no difference. CONCLUSIONS: Leprosy had a negative influence on all of the study variables, indicating the need for immediate physiotherapeutic intervention in individuals with leprosy. This investigation opens perspectives for future studies that analyze leprosy treatment with physical therapeutic intervention.

    .This article explores the deep renovation in the ideological-cultural field that accompanies the return to democracy in the country, as well as the processes that bring about the formation of a new "cultural atmosphere". Besides, through the conceptual and methodological news in the field, it analyses the production that aims at revisiting Peronism at that time. In so doing, it attempts to tackle the continuity of the lines of the debate that started in previous decades, as well as a whole new line that at the beginning of the 80s began with the analyses of the "cultural battle" between politicians and intellectuals brought about by Peronism after its first decline. The magnetism of Peronism over the historiographical field in the 60s and 70s acquires a renewed vigour in the 80s, due to the political and ideological disputes and controversies in the interior of this political tradition in the period of the democratic transition. This new production is undoubtedly a fundamental chapter in the historiography of Peronism, which continues in the following decades and inspires new readings. In this sense, this article attempts to join old and new ideas in the historiographical field, modulated by the changes in Peronism as a political force since its electoral defeat against Radicalism in 1983.

Los implantes osteointegrados proporcionan la forma más rígida de estabilización protésica para soportar las fuerzas masticatorias. Estos implantes pueden ser insertados de forma inmediata o diferida. A la hora de utilizar el colgajo libre de peroné realizamos la implantología de forma diferida a los 6-12 meses debido a la gran cantidad de material de osteosíntesis necesaria para la fijación del colgajo. Cuatro o seis meses después, cuando el proceso de osteointegración ha ocurrido, los implantes son cargados con una rehabilitación dental. Analizamos 12 casos de reconstrucción mandibular con colgajo libre de peroné y su rehabilitación estética y funcional con implantes osteointegrados y un seguimiento mínimo de 2 años. Se han colocado un total de 56 implantes, presentando todos ellos excepto uno, una correcta osteointegración. Todos estos pacientes han recuperado la función masticatoria, y mejorado de forma considerable la competencia labial, la continencia salival, la pronunciación y la armonía facial.Free fibula flap has proved to be one of the most versatile for oromandibular reconstruction due to the available length of bone and the possibility of incorporating a long skin paddle to cover intraoral soft tissues.

En este trabajo, presentamos cuatro pacientes afectos de osteorradionecrosis masiva de la mandíbula que habían fracasado inicialmente con medidas conservadoras y que fueron tratados con resección radical y reconstrucción primaria con un colgajo libre osteoseptocutáneo de peroné. El defecto mandibular tras la resección ósea midió una media de 10 cm e incluyó mucosa intraoral, piel o ambos. En dos casos de reconstrucción, se empleó el colgajo libre de peroné con doble paleta para reconstruir defectos extensos intra y extraorales. Se realizaron osteotomías en el peroné vascularizado en todos los casos para recrear el contorno mandibular. Todos los colgajos sobrevivieron completamente. Tres pacientes curaron primariamente con buenos resultados estéticos y funcionales. Una paciente falleció en el primer mes tras la operación por una pancreatitis aguda y fallo renal.

    Full Text Available This article analyzes forms of cultural production that opposed Peronism in Argentina between 1950 and 1955 in the context of the Cold War. It focuses on representations created by Argentina’s Socialist Party. This party created a series of discourses opposed to Peronism using local and transnational categories that were framed by the country’s own view of the Cold War. The Socialist Party used these discourses to stigmatize Perón’s Argentina as a species of totalitarian state. This article sought to go beyond the traditional perspectives of Cold War historiography, whose focus is on diplomatic and military history and the bulk of whose analysis is devoted to dissecting the United States’ attempts to establish hegemony over Latin America or to describing the phenomenon of justicialismo’s “third position.” This article, on the other hand, sought to use cultural analysis to explore Latin America’s own agency in its adoption of language pertaining to the early Cold War period. Socialists crafted a stylized, and sometimes exaggerated, discourse in which imagery belonging to fascism and, to a lesser extent, Stalinism after the rise of the Iron Curtain, was combined with the local figure of nineteenth century governor Juan Manuel de Rosas.Este artículo analiza formas culturales que se opusieron al Peronismo en Argentina entre 1950 y 1955 en el contexto de la Guerra Fría. El artículo se focaliza en las representaciones creadas por el Partido Socialista Argentino.

Así el Partido Socialista estigmatizó al peronismo como una forma de estado totalitario. Este artículo busca ir más allá de las visiones tradicionales de la historiografía sobre la Guerra Fría basadas en la historia diplomática o militar donde gran parte del análisis daba cuenta de los intentos

    Full Text Available Patients with leprosy may have only nerve involvement without skin changes. These cases are known as pure neural leprosy and can be seen in 10% of leprosy patients. Most patients have mononeuritic or multiple mononeuritic neuropathy patterns. The isolated lesion of the superficial peroneal nerve is uncommonly seen. We report a patient with involvement of this nerve in which there was no thickening of superficial nerves. The performed nerve biopsy showed inflammatory infiltration, loss of fibers and presence of Mycobacterium leprae. We believe that in prevalent leprosy countries we should take in mind the possibility of isolated pure neural leprosy in some patients without skin lesion. In these cases the diagnosis of leprosy is impossible on clinical grounds and nerve biopsy is mandatory.Em alguns casos de lepra podemos encontrar acometimento de nervos periféricos sem manifestações cutâneas. É a denominada lepra neurítica pura que pode ocorrer em até 10% dos casos desta doença. Na maioria das vezes predominam quadros de mononeuropatia ou mononeuropatia múltipla. O acometimento isolado do nervo peroneiro superficial tem sido pouco relatado. Referimos a uma paciente com acometimento isolado deste nervo sem hipertrofia de troncos nervosos. A biópsia realizada mostrou presença de infiltrado inflamatório, perda moderada de fibras e presença do Mycobacterium leprae. Acreditamos que, em países onde a lepra é endêmica, diante de acometimento isolado de nervos periféricos, deve-se pensar na possibilidade de se tratar da forma neurítica pura desta moléstia, mesmo em pacientes sem alterações dermatológicas. Nestes casos o diagnóstico só será possível com a realização de biópsia de nervo superficial.

    Full Text Available Este artículo contribuye a comprender la estructura organizativa del peronismo, la fuerza política dominante en Argentina, a partir de la observación de las designaciones partidarias en el Estado. Para ello el trabajo presenta los resultados de una investigación sobre el alcance, los mecanismos, las motivaciones y los criterios de las designaciones partidarias en el Estado federal argentino, con particular énfasis en lo ocurrido durante la presidencia de Néstor Kirchner (2003- 2007. El argumento más general sostiene que las designaciones han devenido en este período en una herramienta esencial para lograr un control efectivo sobre el aparato estatal mientras que sirven, simultáneamente, para reconfigurar las élites partidarias del peronismo bajo el liderazgo del presidente. Los datos, surgidos de una amplia serie de entrevistas a expertos, permiten finalmente ofrecer un nuevo marco teórico para estudiar el vínculo entre partido y gobierno en el contexto de la democracia argentina contemporánea.This article contributes to the understanding of the organizational structures of peronism, Argentine dominant political force, on the basis of a study on partisan appointments. It presents the main findings of a research on the scope, the workings, the motivations, and the criteria of partisan appointments in the Argentine state, with particular attention to Néstor Kirchner administration (2003-2007. The more general argument contends that appointments became in this period a crucial tool to control the state apparatus while, at the same time, they made it possible to renovate Peronist partisan elites under the leadership of the president. The data, obtained from a large series of expert interviews, make it possible to offer a new theoretical framework for the understanding of party-government linkages in contemporary Argentine democracy.

    Full Text Available Objectives: To evaluate the accuracy of the peroneal nerve test (PENT in the diagnosis of critical illness polyneuropathy (CIP and myopathy (CIM in the intensive care unit (ICU. We hypothesised that abnormal reduction of peroneal compound muscle action potential (CMAP amplitude predicts CIP/CIM diagnosed using a complete nerve conduction study and electromyography (NCS-EMG as a reference diagnostic standard. Design: prospective observational study. Setting: Nine Italian ICUs. Patients: One-hundred and twenty-one adult (≥18 years neurologic (106 and non-neurologic (15 critically ill patients with an ICU stay of at least 3 days. Interventions: None. Measurements and main results: Patients underwent PENT and NCS-EMG testing on the same day conducted by two independent clinicians who were blind to the results of the other test. Cases were considered as true negative if both NCS-EMG and PENT measurements were normal. Cases were considered as true positive if the PENT result was abnormal and NCS-EMG showed symmetric abnormal findings, independently from the specific diagnosis by NCS-EMG (CIP, CIM, or combined CIP and CIM. All data were centrally reviewed and diagnoses were evaluated for consistency with predefined electrophysiological diagnostic criteria for CIP/CIM. During the study period, 342 patients were evaluated, 124 (36.3% were enrolled and 121 individuals with no protocol violation were studied. Sensitivity and specificity of PENT were 100% (95% CI 96.1-100.0 and 85.2% (95% CI 66.3-95.8. Of 23 patients with normal results, all presented normal values on both tests with no false negative results. Of 97 patients with abnormal results, 93 had abnormal values on both tests (true positive, whereas four with abnormal findings with PENT had only single peroneal nerve neuropathy at complete NCS-EMG (false positive. Conclusions: PENT has 100% sensitivity and high specificity, and can be used to diagnose CIP/CIM in the ICU.

    The experiments on the elongation of the tibia in 18 dogs were performed for 10 days using the Ilizarov apparatus with an automatic drive providing the pace of 3 mm/day for 120 moves (group 1) and 180 moves (group 2). The impact of fractionation of distraction on the structure of the peroneal nerve was estimated. In group 1, perineurium micro-injuries and endoneural blood vessel destruction were detected. In group 2, perineurium preserved its integrity and fine-lamellar structure, endoneural blood vessels were also preserved, however, the decrease in the total area of nerve fiber bundles was more pronounced. Morphometric analysis of the preserved myelinated nerve fibers 60 days after the cessation of distraction indicated less marked axonal atrophy and better myelination in group 2.

    Studies of copular forms are extremely relevant to issues in philosophy, psychology, and linguistics. Psychologists have recently argued that the most distinctive aspect of human language is its combinatorial nature (e.g., Gentner, 2003; Spelke, 2003). They argue that this linguistic component might be what separates human from animal cognition.…

    Objective To provide anatomical basis for design of the chimeric fibular composite flap based on the peroneal artery. Methods 30 cadaveric lower extremities were used for this study. The fibular head and the lateral malleolus were used as the landmarks and the calves were divided into the upper, middle and lower segments, respectively. Dissection of the calves was carried out and the following contents were investigated: ① The origin, course and branches of the peroneal arteries; ② The number of the musculocutaneous or septocutaneous perforators of the three segments and the periosteal branches from the peroneal arteries. Results The peroneal artery originated from the tibial artery and travelled immediately posteriorly to the fibular bone after it coursed to the middle segment of the fibular. It continued as the lateral calcaneal artery, giving off the branches to nourish the adjacent bones, muscles, and the skin on the lateral aspect of the lower leg. Among the branches given off, 2 to 8 branches were to the periosteum of the middle and lower 1/3 of the fibular bone, averaging 0.5 to 1.1 in diameter, which were termed fibular periosteal arteries; 1 to 3 branches were to the middle and lower 1/3 of the tibial periosteum, averaging 0.6 to 0.8 in diameter, which were termed tibial periostal arteries; 4 to 8 branches were the musculocutaneous or septocutnaoues perforators supplying the skin on the lateral aspect of the middle and lower segments of the lower leg. After piercing the deep fascia, the septocutaneous perforators anastomosed with the perforators from the anterior and posterior tibial arteries. Conclusions It is anatomically feasible to harvest the chimeric fibular composite flap based on the peroneal artery, depending on the practical clinical needs;one type or multiple types of chimeric flaps can be harvested to reconstruct combined defects of bone and soft tissue.%目的:为腓血管蒂腓骨嵌合组织瓣设计提供解剖学依据。方法用30

    Objective To explore the surgical technique and clinical outcomes of applying the free adipofascial flap nourished by musculocutaneous perforators of the peroneal artery to repair soft tissue defects of the hand. Methods Six cases of skin defects in the hand were treated from December 2007 to October 2009 with free peroneal artery perforator fascial flap. The size of the raised flaps ranged from 5.0 cm × 4.5 cm to 10 cm × 7 cm. In most cases the musculocutaneous branch was chosen as the vascular pedicle for anastomosis.The blood vessels were anastomosed in an end-to-side fashion. The transferred fascial flap was covered with split thickness skin graft, while the donor site was closed directly. Results All the adipofascial flaps survived uneventfully. The skin graft over the fascial flap showed over 90% survival in 4 cases and 80% survival in 2 cases after 7 days. Follow-up time ranged from 3 to 12 months. Flap bulkiness was seen in one case which underwent debulking procedure 3 months later. The appearance of other 5 cases was satisfactory with only slight flap bulkiness. Only a linear scar was left at the calf donor site. Conclusion The free adipofascial flap was a modification of peroneal perforator flaps to minimize morbidity and improve cosmoses of the donor site. The adipofascial flap can also fill the void caused by soft tissue defects and provide better condition for functional reconstruction.%目的 探讨应用游离腓动脉穿支筋膜瓣修复手部软组织缺损,减少供区损伤的方法和临床效果.方法 2007年12月至2009年10月,对6例手部皮肤缺损患者,应用游离腓动脉肌皮穿支筋膜瓣进行修复,切取面积为5.0 cm×4.5 cm~10.0 cm×7.0 cm,以肌皮穿支为蒂.动脉血管蒂与受区血管采用端侧吻合,受区筋膜瓣行断层植皮覆盖.供区创面直接缝合.结果 术后6例筋膜瓣全部存活;术后7 d,筋膜表面植皮成活大于90%4例,80%2例.随访时间为3~12个月,1例皮瓣臃肿,术后3

    Full Text Available En este artículo nos proponemos analizar el sindicalismo petrolero en Comodoro Rivadavia durante el período de la denominada Gobernación Militar (1944 - 1955. Dicha etapa coincidió con el primer peronismo, el cual generó dos sectores antagónicos al interior del principal sindicato de la empresa petrolera estatal, el Sindicato de Obreros y Empleados de YPF. Desde la perspectiva historiografía canónica del peronismo, la disolución del sector "autonomista" ha sido explicada en términos de peronización y cooptación, en el marco del giro conservador que habría adquirido Perón a partir de 1952. A partir del análisis del discurso, nuestra perspectiva busca alejarse de este tipo de argumentos. La disputa entre los dos sectores del sindicato y la disolución del sector autonomista se explicaría a partir de algunos elementos que constituyen el discurso populista: la presentación de un daño, la aparición de un nuevo sujeto político, la partición de la vida comunitaria en dos y la irreductibilidad de dicha partición.In this article we propose to analyze the petroleum unionism in Comodoro Rivadavia during the period of the Military Government (1944 - 1955. This stage coincided with the first Peronism period, which generated two antagonistic groups to the interior of the main trade union of the petroleum state company, the Union of YPF Workers and Employees. From the canonical historiography perspective about Peronism, the dissolution of the autonomist group has been explained in terms of peronización and cooptation, in the frame of the conservative position that Perón would have acquired from 1952.

    Full Text Available Este artículo explora la prensa y las producciones de los dirigentes del Partido Socialista argentino con el objeto de dar cuenta de una de las líneas principales de su prédica: la representada por los distintos usos del término "totalitarismo". Se reconstruye cómo el uso del discurso "antitotalitario" permitió a la dirigencia del partido no sólo condenar, por su asociación con las experiencias europeas, al régimen nacido de la revolución del '43 y al gobierno peronista, sino también cuestionar, por su cercanía con el peronismo, a los comunistas y a los miembros del ala izquierda del mismo Partido Socialista. El recorrido se cierra hacia comienzos de los años cincuenta, momento en que los intelectuales socialistas producen las más densas caracterizaciones del peronismo como fenómeno "totalitario", y justo antes de que la clave "anti-totalitaria" comience a ser cuestionada por la militancia socialista, en particular la juvenil.This article explores the press and the publications of the leaders of the argentine Socialist Party in an effort to account for one of the principal lines of its ideological message: the one represented by the different uses of the term "totalitarianism". It reconstructs the way in which the "anti-totalitarian" discourse allowed the party leadership not only to condemn the regime originated in the revolution which took place in 1943 and the Peronist government which emerged from it by associating both directly with contemporary European experiences, but also to challenge the Communists and left-wing members of the Socialist Party, because of their proximity to Peronism. This ideological itinerary was all but exhausted by the beginning of the '50s, when socialist intellectuals produced their densest characterizations of Peronism as a "totalitarian" phenomenon and just before the"anti-totalitarian" agenda began to be challenged, by grass-roots socialist militants, and particularly by the youth sector of the

    We evaluated the efficacy and robustness of a second generation implantable stimulator for correcting drop foot (DF) in a patient with left-sided hemiplegia over 20 years of functional electrical stimulation (FES) of the common peroneal nerve (CPN). Dorsal flexion and eversion of the affected foot was partially restored by FES of the superficial region of the CPN innervating mostly the tibialis anterior (TA) and partly peroneus longus (PL) and peroneus brevis (PB) muscles. The reasons for implant failure during the long-term follow-up assessment were analyzed and resolving procedures were identified. The stimulator had an average failure rate of once every three years, due to repetitive mechanical load on the lead wires of its internal and/or external unit, and had to be serviced once per year to replace the heel switch integrated into the shoe sole. FES-associated mechanical trauma to the CPN elicited a thickening of the connective tissue around the CPN and a slightly compromised conduction velocity of the CPN. FES of the CPN, with the second generation implantable stimulator, improved gait parameters of the affected leg during the 20 years period. Long-term, daily FES enables a functional and reliable recruitment of nerve fibers, thus providing a sufficient dorsal flexion and optimal eversion of the affected foot to sustain unassisted, almost normal gait. Therefore, the presented implant is suitable for very long-term FES of the CPN. Copyright © 2016 International Center for Artificial Organs and Transplantation and Wiley Periodicals, Inc.

    Objective To explore the feasibility and effectiveness of lateral gastrocnemius muscle branch nerve transferring for deep pe-roneal nerve injury. Methods Thirty-two adult female Sprague-Dawley rats were divided into control group (n=8), sham group (n=8), nerve direct repairing group (n=8) and nerve transferring group (n=8). Twelve weeks after the anastomosis, the nerve anastomosis was observed vi-sually, the length of lateral of gastrocnemius muscle branch (L1), the diameter at the point of entering muscle (D1), the maximum detachable length of nervus peroneus communis (L2), the diameter of deep peroneal nerve (D2) and the distance between branch point and neck of fibu-la (S) were measured. The peroneal nerve functional index (PFI), the amplitude of compound muscle action potential (CMAP), nerve con-duction velocity (NCV), the weight of the tibialis anterior and the creatine kinase (CK) activity of theanterior tibial were compared among groups. Results L10.05). Conclusion It is feasible that lateral head muscular branches of gastrocnemius nerve transferring can repair deep peroneal nerve injury, which is needed to separate superficial peroneal nerve and deep peroneal nerve in the epineurium without damaging nerve for tension free neuroanastomosis. Lateral head muscular branches of gastrocnemius nerve transferring can repair the func-tion after deep peroneal nerve injury.%目的:探讨腓肠肌肌支神经转移术修复腓深神经损伤的可行性和有效性。方法32只成年雌性Sprague-Dawley大鼠分成空白组、对照组、神经直接吻合组(腓深神经直接吻合)和神经转移组(腓肠肌外侧头肌支转移至腓深神经),每组各8只。术后12周,肉眼观察神经吻合口生长情况,测量胫神经各肌支长度(L1)、入肌点处直径(D1)、各肌支起点至腓骨颈平面的距离(S),腓总神经膜内可分离的最大长度(L2)、腓深神经的直径(D2),比较手术前后大鼠患肢腓神经功能指数(PFI)、

    Full Text Available La osteorradionecrosis mandibular supone una complicación grave del tratamiento radioterápico, que a menudo origina una seria deformidad facial. La dificultad para la masticación, la articulación y la deglución son también frecuentes. A pesar de los avances realizados en la última década en radioterapia para tumores de la cabeza y el cuello, las complicaciones por osteorradionecrosis aún se producen. La indicación para una cirugía radical no está claramente definida, pero esta modalidad de tratamiento debe instaurarse cuando las medidas conservadoras han fracasado o cuando prevalece la necrosis ósea y de partes blandas. Las fracturas patológicas o fístulas persistentes son claros indicadores para un abordaje radical. En este artículo se presenta un caso de osteorradionecrosis bilateral mandibular tratada con amplia extirpación quirúrgica y reconstrucción en dos tiempos con dos injertos microvascularizados de peroné.Osteoradionecrosis of the mandible is a serious complication of radiotherapy that often leads to severe facial deformity. Difficulties in mastication, articulation, and swallowing are also common. Despite major improvements in radiation therapy of head and neck cancers during the last decade, osteoradionecrosis complications still occur. The indication for radical surgery is not clearly defined, but this kind of treatment should only be instituted when conservative methods fail or when severe bone and soft-tissue necrosis prevails. Pathological fractures or persistent fistulas are strong indications for a more radical surgical approach. This article reports a case of bilateral osteoradionecrosis of the mandible treated with radical escision and reconstruction in two stages with two fibular osteoseptocutaneous free flaps.

    Full Text Available Introducción: En la actualidad, se considera que el injerto microvascularizado de peroné es la mejor opción de tratamiento para las reconstrucciones mandibulares de defectos óseos mayores de 6 cm. No obstante, debido a su limitada altura, presenta una importante desventaja en cuanto a la rehabilitación protésica, particularmente en aquellos casos de resecciones mandibulares parciales con una hemimandíbula contralateral dentada. Material y métodos: Presentamos un caso clínico de mixoma mandibular tratado mediante resección quirúrgica y reconstrucción mandibular primaria mediante injerto microvascularizado de peroné, al que se sometió a distracción osteogénica vertical para optimizar la posterior rehabilitación implantológica. Resultados: La discrepancia de altura se solucionó completamente y se colocaron tres implantes osteointegrados en el área distraída, lo cual permitió una rehabilitación protésica muy satisfactoria, tanto estética como funcionalmente. Conclusiones: La distracción osteogénica vertical de peroné constituye una excelente opción terapéutica para igualar la altura del peroné a la del reborde alveolar de la hemimandíbula dentada contralateral, tras la reconstrucción de defectos mandibulares extensos, de cara a una posterior rehabilitación implantológica, lo que permite llevar a cabo ésta con resultados, tanto funcionales como estéticos, muy satisfactorios. Además, no presenta los inconvenientes de otras técnicas empleadas en estos pacientes, como el peroné en doble barra (mayor dificultad técnica y mayor riesgo de trombosis en el pedículo y el empleo de injertos "onlay" (morbilidad añadida en la zona de toma del injerto.Introduction: Free vascularized fibular flap is considered the treatment of choice in mandibular reconstruction for extensive bone defects.

    Objective To provide anatomic basis and clinical implication of the composite flap pedicled with the superficial peroneal nerve and its nutrient vessels. Methods 30 specimens of adult cadaveric lower limb were used to observe the branches, distributions and anastomoses of the vessels and nerves in superficial layer of the posterior crural region. Since June 2007, distally based superficial peroneal nerve vascular flaps were applied for repairing 12 cases of distal leg (foot back, heel, etc.) skin and soft tissue defect followed by bone osteomyelitis. Results The nutrient vessels of superficial peroneal nerve formed the rich vascular network, and anastomosed permanently with the subcutaneous vascular network, or anastomosed with muscular branches of long peroneal muscle and EDL. 2~3 anastomosing ramus could be found respectively. The medial anastomosing branches were more closed to the middle groove, with the more larger diameter than that of lateral ones. During the operation procedure.we routinely observed the errhys in the compound flap, which demonstrated the fine blood circulation in the flap. All flap survived after operation, and the recovered osteomyelitis and satisfied flap outline were obtained through the follows up (3 to 6 months).

    Objective To retrospectively analyze the clinical results of peroneal tendon insertion and reconstruction with suture anchors in the treatment of avulsion fractures of the fifth metatarsal base.Methods Five patients (three males and two females) with the fifth metatarsal base fractures were in zone 1, with average seven days of duration before surgery. The result of radiological examination confirmed that all fractures were in zone 1 of the fifth metatarsal base, with some small, comminuted and obviously displaced pieces. After removal of the small comminuted fracture pieces, the peroneal tendon insertion was dissociated and sutured to the fifth metatarsal base by suture anchors (5 mm in diameter) with line. The feet were immobilized by plaster in the vagus position. The patients began to walk with weightbearing six weeks after operation. Results All patients were followed up for at least six months, which showed no deformity of the feet. The function of forefoot valgus and abduction restored to normal. There was no any loss in muscle force compared with the normal side. Conclusions Peroneal tendon insertion and reconstruction by suture anchors is very helpful to solve the problem in the fixation of the small fracture fragments. The function of the peroneal tendon recovers very well. The surgery has the advantages of easy manipulation and small area of dissection, without requirement of secondary surgery.%目的 回顾分析带线锚钉缝合固定腓骨肌腱治疗第五跖骨基底部撕脱性骨折的临床疗效.方法 5例第五跖骨基底部1区骨折患者(男3例,女2例),术前平均病程7 d.影像检查发现5例均为第五跖骨基底部1区骨折,骨折块较小、粉碎且明显移位.手术去除第五跖骨基底部粉碎骨折块,游离腓骨肌腱止点,用直径5 mm带线锚钉将腓骨肌腱止点编织缝合在第五跖骨基底部,石膏托将患侧足固定于外翻位.术后6周开始逐渐负重行走.结果 本组5例患

    Purpose The regeneration effects of nerve growth factor(NGF)on superior cervical ganglia innewborn mice destroyed by vincristine(VCR)and peroneal nerve of adult rats destroyed by grip were studiedby morphological methods. Methods Superior cervical ganglia. The Qunming newborn mice at 2 dayswere divided into 3 groups: experiment, control and blank. The experiment animals were injected with VCR,10 μl/g of body weight at a concentration of 0.02 mmol/L. Simultaneously, the NGF was injected 2,5,10μg/g of body weight, respectively. But the control animals were only injected with VCR at the same dose.The blank control animals weren' t treated anything. All of these chemicals were injected once a day for 4days. 24h after the last injection, the superior cervical ganglia were dissected out and analyzed their size andmorphology. Peripheral nerve. The peroneal nerve of SD adult rats were destroyed by grip, and divided into2 groups: experiment and control. The experiment rats were injected with NGF 2,4 and 8 μg/kg of bodyweight respectively, near the gripped nerve,once a day for 12 days after 24 h of the injury. 24 h after the lastinjection, the perone al nerve and extensor longus digitorum were dissected out and analyzed their morphologyand counted the number of nerve fiber at proximal and distal injury. Results VCR injection in newbommice produced severe atrophy of superior cervical ganglia. And the neuronal cells apoptosed and decomposed.Simultaneous injections of NGF prevented the noxious effects of VCR, and resulted in an increase intransverse diameter from 61 to 95 percent and the total number of neuronal cells from 59 to 70 percent. Thisimproved degree was related to the dose of NGF. Furthermore, NGF obviously improved the structure of peroneal nerve and extensor longus digitorum. And this effect was the best in the high dosage. ConclusionsNerve growth factor has an obvious regeneration effects in superior cervical ganglia of newborn mice destroyed by VCR and

    Full Text Available En el presente artículo se reconstruye la investigación que Rodolfo Walsh realizó sobre el enfrentamiento que costó la vida de Rosendo García, Domingo Blajaquis y Juan Zalazar y que publicó en siete notas en el semanario CGT entre el 16 de mayo y el 27 de junio de 1968. Aquellas notas son contrastadas con su publicación posterior en formato de libro como ¿Quien mató a Rosendo? en mayo de 1969 y se busca destacar las diferencias entre ambos formatos y contextos. Estas diferencias permiten relevar el contexto político acelerado en que se produjeron y la gran distancia entre un momento y otro a pesar de que transcurrió solo un año entre ambos. Con ello se pretende revisitar una de las investigaciones menos abordadas de Walsh y ponerla en contexto al interior de una etapa político-sindical poco estudiada, especialmente los significados de la división de la CGT y el peronismo, en tanto Walsh había retomado su militancia política y estrechado sus primeros vínculos con una de las fracciones del peronismo en disputa.In the present article we reconstructed Rodolfo Walsh's research about the death of Rosendo García, Domingo Blajaquis and Juan Zalazar that he published in seven notes in the weekly CGT between May and June in 1968. Those notes are compare with his later publication of the research as a the book ¿Quien mató a Rosendo? in May, 1969. We try to emphasize the differences between both formats and contexts because those differences allow as to relieve the critical political context in which they took place. The article underline of the worst approached investigations of Walsh and put it in its context of the meanings of the division of the CGT and the Peronism, considering that Walsh had taken again his political militancy and had make his first links with one of the fractions of the Peronism in dispute.

    The purpose of this application is to conserve the accustomed understanding and usage of the fur seal name Arctocephalus F. Cuvier, 1826 by the designation of Phoca pusilia Schreber, [1775] as the type species, thus conserving also the name Callorhinus Gray, 1859. At present Phoca ursina Linnaeus, 1758 is the valid type species of both Arctocephalus and Callorhinus. The name Arctocephalus relates to a genus of some seven fur seals from the southern hemisphere, while Callorhinus is used for the single species C. ursinus (Linnaeus) from the northern hemisphere. It is also proposed that the universal understanding of the names Otaria Peron, 1816 and Eumetopias Gill, 1866 should be conserved for the southern and northern sea lions respectively by designating Phoca leonina Molina, 1782 (for which the valid specific name is P. byronia de Blainville, 1820) as the type species of Otaria. At present Phoca jubata Schreber, [1776] is the type species of Otaria and the name Otaria is a senior subjective synonym of Eumetopias. The four genera Arctocephalus, Callorhinus, Otaria and Eumetopias are all placed in the family OTARIIDAE Gray, 1825.

    Objective To evaluate the usefulness of the short-segment nerve conduction studies (SSCSs,inching test) of the peroneal nerve across the fibular head in order to diagnose and localize the site of entrapment of the nerve.Methods Fifty-four patients with suspected peroneal nerve palsy and 30 controls were studied.The symptoms all occurred in unilateral leg,involving 25 left legs and 29 right legs.Both long segment motor nerve conduction studies (LSMCs) and SSCSs were performed in all patients and controls.SSCSs were obtained at 2 cm intervals,starting 6 cm proximal (P6,P4 and P2) and 4 cm distal (D2 and D4) ending to the fibular head prominence (P).Results When nerve conduction of the entire 10 cm segment across the fibular head was tested by the conventional method,only 40 showed reduction in amplitude or slowing of motor conduction velocity or both.However,with SSCSs,54 peroneal nerves were all discovered abnormal.The results of comparison of conventional methods suggested that there were significant differences in conduction velocity between the fibular head-Ankle segment and the knee-fibular head segment in the case group,the latter ((33.63 ± 9.29) m/s) being slower than the former ((47.92 ± 4.04) m/s;t =9.776,P =0.000),while there was no obvious abnormality in the control group.The results of the control group detected by SSCSs showed that there was no significant difference between the left and right sides of the mean amplitude of the stimulation points and the mean time of segmental nerve conduction.Therefore,we set the exception criteria as the segmental nerve conduction time is longer than the corresponding control group (i + 2 s),and the CMAP amplitude of proximal stimulation point decreased by more than 20% than the adjacent distal segment.In accordance with this standard,we found that the lesions were located in P6 to P4 in 2/54 (3.7%) legs,P4 to P2 in 4/54 (7.4%) legs,P2 to P in 43/54 (79.6%) legs,P to D2 in 12/54 (22.2%) legs,D2 to D4 in 3

    Full Text Available El objetivo del presente trabajo es valorar los resultados funcionales y estéticos de reconstrucciones complejas orofaciales, realizadas mediante la asociación de dos colgajos libres simultáneos de peroné y radial. Se ha realizado este tipo de reconstrucción en tres pacientes con buenos resultados funcionales y estéticos. La reconstrucción con dos colgajos libres está indicada en defectos complejos en los que la reconstrucción con un solo colgajo no obtendría resultados estéticos y funcionales adecuados. Cada colgajo se selecciona por sus características que lo hacen ideal para cada tipo de defecto, óseo y de partes blandas con la finalidad de conseguir un resultado estético y funcional superior al que se obtendría con un solo colgajo.The aim of this paper is to evaluate the functional and aesthetic results of complex orofacial reconstructions by means of the combination of two simultaneous free flaps (fibula osteocutaneous and radial forearm flaps. Three patients who have undergone this kind of reconstruction are presented with good functional and aesthetics results. Reconstruction with two free flaps is indicated in complex defects in which reconstruction with a single flap would not obtain adequate aesthetic and functional results. The choice of each particular flap depends on its specific characteristics that make it ideal for the reconstruction of each particular type of defect, osseous defects and soft tissue defects, with the aim of obtaining a better result than that obtained with the use of a single flap.

    Objective To summarize the clinical experience of repairing soft tissue defect in dorsal pedis with reversed fascia pedicled peroneal perforating branch sural neurofasciocutaneous flap, and to explore surgery matters needing attention and measures to prevent flap necrosis. Methods Between August 2000 and April 2009, 31 patients with soft tissue defects in dorsal pedis were treated with reversed fascia pedicled peroneal perforating branch sural neurofasciocutaneous flaps.There were 23 males and 8 females with a median age of 34 years (range, 3-65 years). Defects were caused by traffic accident in 20 cases, by machine in 2 cases, and by crush in 2 cases. The time from injury to admission was 1-32 days (mean, 15 days).And 6 cases had chronic ulcer or unstable scar excision with disease duration of 6 months to 10 years, and 1 case had squamous carcinoma with disease duration of 5 months. The wounds were located in medial dorsal pedis in 12 cases and lateral dorsal pedis in 19 cases; including 14 wounds near the middle metatarsal and 17 wounds beyond the middle metatarsal (up to the metatarsophalangeal joint in 10 cases). All cases accompanied with bone or tendon exposure. Five cases accompanied with long extensor muscle digits tendon rupture and defect, 1 case accompanied with talus fracture, 1 case accompanied with talus fracture and third metatarsal fracture. The size of the wounds ranged from 6.0 cm × 4.5 cm to 17.0 cm x 10.0 cm. The size of the flaps ranged from 8.0 cm × 5.5 cm to 20.0 cm × 12.0 cm. The donor sites were resurfaced by skin graft. Results Seventeen flaps survived uneventfully, wounds healed by first intention. Distal epidermal or superficial necrosis occurred in 6 flaps at 5-12 days after operation, wounds healed by dressing change or skin graft. Distal partial necrosis occurred in 8 flaps (7 in medial dorsal pedis and 1 in lateral dorsal pedis) at 7-14 days after operation, wounds healed by skin graft in 3 cases, by secondary suture in 3 cases

    Full Text Available El fibroma osificante (FO es una lesión fibro-ósea poco frecuente que afecta generalmente a mujeres de mediana edad, localizándose usualmente en la zona posterior de la mandíbula. Clínicamente, el paciente puede presentar un aumento de volumen asintomático de evolución lenta que genera desplazamiento de las piezas dentarias como manifestación temprana. Radiográficamente se caracteriza por ser una lesión radiolúcida en sus primeras etapas, que evoluciona a una lesión mixta con zonas de radioopacidad variable para finalizar como una lesión extremadamente radioopaca. El tratamiento varía de acuerdo a su tamaño y puede variar desde una excisión conservadora, a una resección en bloque más reconstrucción mediante injerto óseo. Presentamos un caso de FO de gran tamaño en un paciente de 22 años. Se describen las características específicas, histológicas y clínicas. Se presenta de acuerdo a la extensión de la lesión, una conducta terapéutica con resección en bloque del segmento mandibular afectado con posterior reconstrucción con injerto microvascularizado de peroné.Ossifying fibroma (OF is an uncommon fibro-osseous lesion that generally affects middle-aged women and is usually located in the posterior jaw. Clinically, the patient may present a slow-growing, asymptomatic mass with tooth displacement as an early manifestation. Radiographically, OF is characterized as a radiolucent lesion in its early stages that progresses to a mixed lesion with variable radiopaque areas and finally evolves into an extremely radiopaque lesion. Treatment depends on the size of the tumor and ranges from conservative surgery to block resection followed by reconstruction with bone grafts. The specific clinical and histological characteristics of the case of a 22-year-old patient with a large OF are described. The case is reported here due to the tumor extension and therapeutic approach consisting of block resection of the affected jaw segment

    Objective To study the distribution of the dominant perforators(the diameter ≥ 0.8mm)of the peroneal artery with color Doppler flow imaging(CDFI)for the purpose of anatomical preparations for the perforator sural neurocataneous flap. Methods The dominant perforators of the peroneal artery(DPPA)were studied with CDFI on bilateral legs of 20 healthy volunteers.The numbers,diameters and locations of the perforators were recorded for a statistical analysis.From Jan.2005 to Jan.2009,51 free or pedicled sural neurocutaneous flaps supplied by a single DPPA were designed and harvested to repair the defects near the ankle(n =22),at the leg(n = 15)and the forefoot or hand dorsum (n = 14).The perforators were located preoperatively with CDFI and accuracy of CDFI was evaluated intraoperatively.The causes of false results were analysed to improve examining techniques. Results The average number of DPPA was 4.2 with the average diameter of(1.13 ±0.24)mm(0.80-1.90 mm).They were located in the second to ninth segment of the line from the fibular caput to the tip of lateral malleolus which was equally divided into nine segments.The largest DPPA was(1.43 ± 0.29)mm(1.00-1.90mm)in diameter and most of them were located in the third to fifth segment(80.4%).The average diameter of the lowest DPPA was(1.02 ±0.16)mm(0.80-1.30 mm)and they were located between the sixth to ninth segment.The total 169 DPPA as well as the largest ones mostly appeared in the middle third of the leg.All of the 51 flaps were transplanted successfully without necrosis,and no vascular problems occurred.Preoperative CDFI examination had a 93.6% true-positive rate and an 88.0% positive predictive value.What should be demonstrated was that if just considered the cases after Dec.2007,the true-positive rate was 97%,and the positive predictive value was 93.9%. Conclusions According to the distribution characteristics of DPPA,a sural neurocutaneous flap pedicled with one of this relatively large perforator can be

Los cañeros tucumanos cuentan con una larga tradición asociativa que se inicia a finales del siglo XIX con la modernización de la agroindustria azucarera, con la particularidad de la coexistencia de varias asociaciones gremiales surgidas como consecuencia de las recurrentes crisis del sector y de disputas intersectoriales. De esta forma, en este trabajo analizaremos el proceso por el cual el gremio cañero abandonó su tradición asociativa disgregada para dar lugar a la conformación de un gremio unificado, denominado Unión de Cañeros Independientes de TucumánThis paper addresses the unification of “cañero tucumano” guil on the origins of Peronism. Tucuman cane growers have a long tradition of associations that began in the late nineteenth century with the modernization of the sugar industry, with the particularity of the coexistence of several trade associations that arise from the recurrent crises in the sector and cross-cutting disputes. Thus, in this paper we analyze the process by which the union abandoned its tradition of associations cane astray, lead to the formation of a unified guild called Independent Union of Sugarcane Tucumán

    Objective In an attempt to clarify the usefulness of combined nerve and muscle biopsy in the diagnosis of neuromuscular disease when compared with traditional sural nerve biopsy.Methods Fifteen biopsies of superficial peroneal nerve (SPN) and peroneus brevis muscle ( PBM ) by one incision performed within one neurological clinic were reviewed.All patients had peripheral neuropathy while 3 of them had myopathy clinically.The diagnostic significance of SPN and PBM biopsies were classified into 3 grade: essential,helpful,no value.Results Of 15 SPN and PBM biopsies,7 showed essential pathological findings which reached the etiological diagnosis, including 5 definite vasculitis, 1 inflammatory demyelinating polyneuropathy and 1 amyloid neuropathy.Five biopsies are helpful for etiological diagnosis,including demyelinating neuropathy,mild inflammation,and microvascular lesion,et al.Three biopsies are of no value for etiological diagnosis which only have nonspecific change such as type 2 fiber atrophy,neurogenic atrophy and axonal degeneration et al. Finally,SPN and PBM biopsies made the definite etiological diagnosis possible in 12 patients.Conclusions SPN and PBM biopsy improved the yield of specific pathological and etiological diagnosis of neuropathy and myopathy such as vasculitis and amyloidosis with minor trauma and side effect.Further clinical and pathological studies will be necessary for a better practice of combined nerve and muscle biopsy.%目的 开展单一切口下的腓浅神经与腓骨短肌联合活体组织检查,通过回顾相关病例的临床和病理资料,分析联合活体组织检查的诊断意义.方法 共15例患者,女性7例,男性8例,年龄14 ~72岁,其中亚急性6例、慢性9例,均患有周围神经病,3例临床上合并肌肉病.周围神经病的临床类型包括对称性感觉和运动性神经病7例、多发性单神经病5例、对称性感觉性神经病3例.在外踝前上方纵切口,取材腓浅神经与腓骨短肌.

    , así como sobre el proceso de formación de identidades nacionales en América Latina, y más específicamente Brasil y Argentina.---------------------------------------------------------------------------This article has as its main objective the analysis of sport as a political instrument during the first Vargas Era, in Brazil, and during Juan Domingo Perón’s first two mandates, in Argentina. Both Vargas and Perón tried to identify their political regime to the victories on the sport field. Therefore, the State’s control over sport and its usage by the means of political propaganda aimed at creating a link of national identification between sport and government, reaffirming the new models of nation and citizens produced by varguism and peronism. The article also attempts analyzing the differences in the approach of each government in their models of intervening in the internal structure of sport. We hope this dissertation may bring significant contributions to the debate on the production of political ideology through sport, as on the process of the making of national identities in Latin America, especially in Brazil and Argentina.

    Serial ultrasound examination of four mature female sevengill sharks (Notorynchus cepedianus) was carried out over 18 months. Monitoring the reproductive cycle and development of follicles and fetuses in sharks in a noninvasive manner using this technique has not been reported previously. Sharks were caught out of the "Oceanarium" tank by divers using a specially made catch-out bag, and brought to a holding area for examination. A behavior scoring system was used to monitor the impact of regular handling on the well-being of the animals. Ultrasound showed the growth and regression of follicles in sevengill ovaries, and allowed an approximation of the reproductive stage of these sharks. Monitoring behavior at five time points during the procedure showed that regular handling of sharks for clinical studies could be done with minimal impact on animal welfare. The ability to follow reproductive events in elasmobranches using ultrasonography is an important step in the application of assisted reproductive technology in these species. Assisted reproductive technology, such as monitoring female reproductive cycles and artificial insemination, could potentially be used to maintain genetic diversity and compliment aquaria-based breeding programs for endangered species such as the gray nurse shark (Carcharias taurus).

    The purpose of this investigation was to determine the pre-activity of the tibialis anterior (TA), peroneus longus (PL), and peroneus brevis (PB) prior to foot contact during three conditions. Twenty-six subjects (age 22 +/- 2 yrs; 15 male, 11 female) with no lower extremity injuries reported for data collection. Data were collected from each subject's dominant leg using surface electromyography (EMG). EMG electrodes were applied over the test muscles using a standard protocol. A heel-toe strike transducer was affixed to the bottom of the subject's shoe. The subject completed two randomized trials of walking on a treadmill (5.6 kph), jogging on a treadmill (9.3 kph) and drop landing from a 38 cm box. Isometric reference positions (IRPs) were recorded for the TA, PL, and PB. Muscle data were normalized to IRPs and the average processed EMG for the 200 ms prior to heel strike during walking and jogging and prior to toe strike when dropping from the box was used for analysis. A one-way repeated measures MANOVA was used to detect differences in pre-activity of the muscles between the three conditions. Univariate tests were used to determine differences for each muscle and Tukey's was applied post hoc to determine individual effect differences. The MANOVA revealed significant differences among the three conditions (F2.50 = 10.770; P < .0005). Average TA activity was significantly higher during jogging (Tukey's; P < .0005). Significant differences existed between each condition for the TA. Average PL and PB activity was significantly higher when drop landing (Tukey's; P < .0005). There was no significant difference between walking and jogging for the PL and PB. The amount of muscle pre-activity occurring before heel or toe strike provides useful information for the examination of reaction times to unexpected inversion during dynamic activities.

  18. Consistent paternity skew through ontogeny in Peron's tree frog (Litoria peronii.

    Directory of Open Access Journals (Sweden)

    Craig D H Sherman

    Full Text Available BACKGROUND: A large number of studies in postcopulatory sexual selection use paternity success as a proxy for fertilization success. However, selective mortality during embryonic development can lead to skews in paternity in situations of polyandry and sperm competition. Thus, when assessment of paternity fails to incorporate mortality skews during early ontogeny, this may interfere with correct interpretation of results and subsequent evolutionary inference. In a previous series of in vitro sperm competition experiments with amphibians (Litoria peronii, we showed skewed paternity patterns towards males more genetically similar to the female. METHODOLOGY/PRINCIPAL FINDINGS: Here we use in vitro fertilizations and sperm competition trials to test if this pattern of paternity of fully developed tadpoles reflects patterns of paternity at fertilization and if paternity skews changes during embryonic development. We show that there is no selective mortality through ontogeny and that patterns of paternity of hatched tadpoles reflects success of competing males in sperm competition at fertilization. CONCLUSIONS/SIGNIFICANCE: While this study shows that previous inferences of fertilization success from paternity data are valid for this species, rigorous testing of these assumptions is required to ensure that differential embryonic mortality does not confound estimations of true fertilization success.

    Full Text Available When a melito-diabetic patient presents trophic infected injury on the limb, it is essential an evaluation of the circulatory conditions for therapeutic procedures orientation. In some circumstances, although arterial pulsation is absent, there is no ischemia of tissues. In these cases, the maintenance treatment, with eventual resection of the necrosed and infected tissues may be adopted. Evolution of 70 diabetic patients with trophic injuries on extremities were submitted to a maintenance treatment. Age of patients varied from 28 to 88 years, with an average of 56.8. The most occurrence was verified in women, with 42 cases. Diabetes non-dependant on insuline (type II was observed in 64 patients (91.5%, being the remaining 6 patients of type I. Diabetic retinopathy was observed in 14 (20% of the patients, neuropathy in 22 (31% and nephropathy in 8 patients (11.4%. All the patients presented arterial pulsation until the popliteal region. They were divided in 2 groups, considering trunk arteries of legs: Group I, pervial legs arteries, composed by 48 patients; Group II, occluded legs arteries, with 22 patients. In what refers to the anatomic local of the injuries, patients were classified in three groups: Group A, formed by 32 patients (45.7%, presenting injuries in one or two toes only, without affecting the metatarsic region; Group B, formed by 16 patients (22.9%, trophic injuries affecting the metatarsic region and Group C, formed by 22 patients (31.4%, injuries affecting the calcaneous region. Injuries in both of the groups were caused by mechanical traumatism. Duration of the injury in the inferior member varied from 7 to 48 days, resulting in a 12 days average. Analyzing pervicacity in trunk arterias and evolution of patients, it may be observed that there has been a significantly better result in those with all the pulses present (81.3% x 45.5%(p0,05(Table IV.

    Full Text Available In this article we analyze the health policy structuring process in Argentina. Our aim is to examine the transformation of the public health system during the first Peronist government in Jujuy (1946-1952. The attention is given to the performance of Emilio Navea, head of the health area. We analyze their academic background, political relations, initiatives and reforms implemented to the local health system. The intense activity of Navea in this area contributed largely to its appointment as a lieutenant governor candidate for the 1951 elections on behalf of the political force that supported Perón in the province.

    Full Text Available This article is based upon a multi-archival research in the diplomatic archives of seven different countries: Argentina, Brazil, Chile, Spain, Italy, Perù and Portugal. It analyzes the attempt of the Peròn government to form a bloc of Latin countries, gathering under its hegemony, and with the support of the Vatican, the catholic nations of Europe and America. Known as the “third position”, the idea of creating such a bloc failed once the Cold War imposed its rules, laying the ground for an odd alliance between most catholic countries, the Vatican and the United States. As a consequence, Peròn’s policy abandoned its religious matrix and drifted progressively toward third-worldist horizons. At the same time, the abortion of the Latin bloc showed the capability of the bipolar system to erode the notion of a Latin civilization, diluting it into the broadest one of the Christian West

Conocido como la “tercera posición”, ese bloque fracasó a medida que la guerra fría imponía sus reglas y creaba las condiciones de una inédita alianza entre la mayoría de los países católicos y el Vaticano con Estados Unidos. Como consecuencia la política peronista se alejó de su origen confesional para evolucionar hacia una ideología cada vez más tercermundista.

    To investigate the clinical therapeutic effects of anchors, peroneus brevis tendon augmentation and plantaris muscle tendon covering on the reconstruction of achilles tendon rupture caused by corticosteroids injection. From March 2005 to April 2010, the clinical data of 10 patients with acute achilles tendon rupture repaired with suture anchors, peroneus brevis tendon augmentation and plantaris muscle tendon covering were retrospectively analyzed. The achilles tendon rupture was caused by corticosteroids injection. There were 8 males and 2 females with a mean age of (46.80 +/- 2.83) years old(ranged from 21 to 68 years). Postoperative complications, the range of movement of affected foot, number of consecutive heel raises and single leg jumpings were recorded. Functional recovery of achilles tendon were assessed according to ankle and hindfoot scores of the American Orthopedic Foot Ankle Society (AOFAS). All patients were followed up for 12 to 18 months with an average of 13.5 months. No wound infection, re-rupture and rejection reaction were found. At the last follow-up, there was no significant difference in the range of movement between affected foot (54.5 +/- 6.3) degrees and unaffected foot (56.8 +/- 3.8) degrees (t = 0.989, P = 0.336). The affected foot could raise heel and do single-leg hops for 10 times continuosly. There was significant difference in AOFAS between preoperative score (67.3 +/- 7.6) and postoperative score (95.5 +/- 7.6) (t = 8.297, P = 0.000);and there was no significant difference between affected foot scores (95.5 +/- 7.6)and unaffected foot scores (98.5 +/- 6.3) (t = 0.961, P = 0.349). Function recovery of achilles tendon: 9 cases were good, 1 case was fine. Anchors, peroneus brevis tendon augmentation and plantaris muscle tendon covering for the reconstruction of achilles tendon rupture caused by corticosteroids injection is a reliable and effective method, with advantage of simple operation, dependable fixation and less complications.

    The volcanic spreading model by Borgia et al. (2014) is accurate in describing the extensional structures found on the edifice and the radial compressional structures existing all around the base of Amiata Volcano. Volcanic conduits, extensional structures, and direct contact between the volcanic rocks and the Tuscan Units, constitute the hydraulic connection between the potable fresh-water aquifer contained in the volcanites and the underlying hydrothermal system. Therefore, gaseous phases tend to flow upward (particularly through faults) carrying pollutants into the freshwater aquifer, while the freshwater recharges (also through primary permeability) the exploited geothermal fields.

    Full Text Available A 25-year-old white man, right after bilateral rhytidoplasty, presented with agitation, necessiting use of haloperidol. Some hours after, he developed severe pain in his legs and a diagnosis of neuroleptic malignant syndrome (NMS was considered. Even with treatment for NMS he still complained of pain. A diagnosis of lower limb compartment syndrome (CS was done only 12 hours after the initial event, being submitted to fasciotomy in both legs, disclosing very pale muscles, due to previous ischemia. This syndrome was not explained only by facial surgery, his position and duration of the procedure. It can be explained by a sequence of events. He had a history of pain in his legs during physical exercises, usually seen in chronic compartment syndrome. He used to take anabolizant and venlafaxine, not previously related, and the agitation could be related to serotoninergic syndrome caused by interaction between venlafaxine and haloperidol. Rhabdomyolisis could lead to oedema and ischmemia in both anterior leg compartment. This report highlights the importance of early diagnosis of compartment syndrome, otherwise, even after fasciotomy, a permanent disability secondary to peripheral nerve compression could occur.Logo após ritidoplastia bilateral, um jovem de 25 anos apresentou agitação, necessitando uso de haloperidol. Algumas horas após, desenvolveu dor intensa em membros inferiores, e o diagnóstico de síndrome neuroléptica maligna foi considerado. Mesmo com o tratamento para tal, persistiu com dor. Após 12 horas do início do quadro, foi realizado o diagnóstico de síndrome compartimental de membros inferiores e o jovem foi submetido a fasciotomia bilateral. Uma seqüência de eventos desencadeou esta síndrome, já que sua ocorrência dificilmente seria justificada pela cirurgia facial e/ou posição do paciente durante o procedimento. O jovem apresentava previamente dor em membros inferiores aos exercícios, sugerindo a ocorrência de uma síndrome compartimental crônica. Ele fazia uso de anabolizantes e venlafaxina, não relatado no início do quadro, e a agitação poderia ser explicada por uma síndrome serotoninérgia desencadeada pela interação deste último medicamento e haloperidol. A rabdomiólise secundária a estes eventos causou edema e isquemia nos compartimentos anteriores de ambos os membros inferiores, levando a uma compressão secundária do nervo fibular. O caso em questão ilustra a importância do diagnóstico precoce da síndrome compartimental pois, caso contrário, mesmo com fasciotomia, uma complicação permanente devido à compressão de nervos periféricos pode se estabelecer.

    The case of a 70 years old patient of masculine sex is presented. After having suffered a traumatism in the left inferior limb and having fulfilled the suitable treatment, the patient presented new signs and symptoms that led him to the department of Orthopedics and Traumatology. With the initial exams and treatment no improvement was obtained, thus doctors decided to opt for the surgical treatment. It could be observed the presence of an osteolytic lesion of approximately 5 cm and the pertinent samples were taken to carry out biopsies of the muscle and the bone. Results didn't lead to a definitive diagnosis. The result of new exams required an inter-consult with the Service of Urology, to obtain the diagnosis of prostatic adenocarcinoma. The revision of the national and international literature didn't report any similar case; the atypical localization of the metastasis is what led to the preparation of the case for its knowledge and diffusion, for what it can contribute to the experience of professionals specialized in orthopedics or urology.

    Se presenta el caso de un paciente de sexo masculino, de 70 años de edad, que tras haber sufrido un traumatismo en el miembro inferior izquierdo y cumplir con el tratamiento indicado, presentó nuevos signos y síntomas que lo llevaron a acudir a la consulta de Ortopedia y Traumatología. Con los exámenes y tratamiento iniciales no se obtuvo mejoría, por lo que se decidió optar por el tratamiento quirúrgico. Pudo observarse entonces la presencia de una lesión osteolítica de aproximadamente 5 cm de longitud y se tomaron las muestras pertinentes para realizar biopsias del músculo y del hueso, cuyos resultados no llevaron a un diagnóstico definitivo. El resultado de nuevos exámenes requirió de la interconsulta con el Servicio de Urología, para llegar al diagnóstico de adenocarcinoma prostático. La revisión de la literatura nacional e internacional no reportó ningún caso similar; la localización atípica de la metástasis es lo que condujo a la preparación del caso para su conocimiento y difusión, por lo que puede aportar a la experiencia de los profesionales especializados en ortopedia o urología.

    Anatomic variants of the peroneal tendons may cause tendon disorders. Moreover, there is a lack of evidence on how to address chronic tendon pathology when a variant of the peroneal tendons is causing the patient's symptoms. We present a patient with an uncommon peroneal muscle presentation: a single muscular belly dividing into both the peroneus longus and brevis tendons. After extensive debridement of tendinopathic tissue, primary repair or tenodesis was not possible; therefore a unique solution for this problem was performed, reconstructing both peroneal tendons using a semitendinosus allograft.

    Anthropogenic activities such as phosphate fertilizers, industrial wastewater effluents derived from the mining process or wastewater sludge represent the main source of metal contamination in the environment (Adriano, 1986). heavy metal toxicity disrupts natural ecosystems and affects the food chain, leading to health problems in humans and animals. Morocco, mainly the southern region, has a large number of metalliferous sites, some of which are being exploited while others have been abandoned. (Author)

    CONCLUSION: Despite its frequent occurrence, a drop foot associated with peroneal nerve entrapment by an osteochondroma is not easily remembered and diagnosed. Especially in pediatric cases, inadequate clinical consultation and a lack of appropriate radiologic studies may result in a delay in diagnosing peroneal nerve lesions.

    Full Text Available El artículo explora los procesos locales y transnacionales que llevaron a la creación de la Asociación Argentina por la Libertad de la Cultura en diciembre de 1955. La Asociación era la filial del Congreso por la Libertad de la Cultura, fundado en 1950 en Berlín como parte de la estrategia cultural estadounidense durante la Guerra Fría. Basado en el análisis de un amplio espectro de publicaciones e instituciones, el texto rastrea la densa red de relaciones personales, institucionales, ideológicas y políticas entre los intelectuales antiperonistas argentinos y entre ellos y sus colegas extranjeros que llevaron a la fundación de la Asociación. Estas relaciones, desarrolladas desde la década de 1930 y profundizadas por la experiencia peronista y la Guerra Fría, fueron facilitadas por trayectorias y temáticas comunes tales como la defensa de la libertad política y cultural y de la superioridad del mundo occidental, el antifascismo y el anticomunismo. El análisis, parte de un proyecto más amplio en curso, sienta las bases para el estudio futuro de la historia de la Asociación y de las redes intelectuales anticomunistas en América Latina durante la Guerra Fría.This article explores the local and transnational processes that resulted in the creation of the Asociación Argentina por la Libertad de la Cultura in December, 1955. The Asociación was a branch of the Congress for Cultural Freedom, which was created in Berlin in 1950 as part of the American cultural strategy during the Cold War. Based on the analysis of a broad group of publications and institutions, the text traces the dense network of personal, institutional, ideological and political relations among the anti-Peronist Argentine intellectuals and between them and their European colleagues that led to the creation of the Asociación. Those relations, developed since the 1930s and deepened by the Peronist experience and the Cold War, were facilitated by common trajectories and themes such as the defense of political and cultural freedom and the superiority of the Western world, anti-fascism, and anti-communism. The analysis, part of a larger ongoing project, also sets the basis for future studies on the history of both the Asociación and anti-communist intellectual networks in Latin America during the Cold War.

    Full Text Available OBJETIVOS: O objetivo deste estudo foi analisar a influência da bandagem funcional de tornozelo no tempo de reação do fibular longo de indivíduos sadios. MÉTODOS: A amostra foi composta por oito indivíduos do gênero masculino, fisicamente ativos, sem histórias prévias de lesões de tornozelo e, com os resultados negativos aos testes de instabilidade articular de tornozelo. Foram usados como instrumentos da pesquisa, a bandagem funcional de tornozelo tipo bota fechada, para realizar o teste uma plataforma capaz de inclinar 30o no plano frontal simulando a entorse lateral do tornozelo e um eletromiógrafo de oito canais (Bortec Electronics Incorporation, Canadá para aquisições dos sinais eletromiográficos. Os sinais EMG foram coletados juntamente com o sinal da plataforma (sincronismo. A coleta dos dados foi realizada em dois momentos, primeiramente sem a bandagem e logo após com a bandagem. RESULTADOS: Os indivíduos tinham idade média de 23,3 anos (± 2,8, massa corpórea de 74,4kg (± 9,4, estatura de 1,7m (± 0,4 e IMC de 23,7kg/m2 (± 2,4. O estudo encontrou diferença estatisticamente significativa p = 0,018 na situação da bandagem funcional de tornozelo com diminuição do tempo de reação do fibular longo. CONCLUSÃO: Acreditamos que esta melhora se deva ao íntimo contato da bandagem com os receptores cutâneos do tornozelo, aumentando a ativação do reflexo fibular, com consequente ganho proprioceptivo e, assim, aumentando a habilidade dos sujeitos em responder a situações súbitas de entorses. O estudo demonstrou diminuição no tempo de reação do fibular longo de indivíduos sadios com o uso da bandagem funcional de tornozelo quando submetidos à inclinação lateral súbita do tornozelo.OBJECTIVE: The aim of this study was to analyze the influence of the ankle functional tape on long fibular reaction time in health subjects. METHODS: The sample was composed of eight physically active male subjects, without ankle injury history and with negative results on ankle joint instabilities tests. The instruments used in this research were an ankle functional tape(closed boot type, a platform capable to 30° frontal inclination and an eight-channel electromyograph (Bortec Electronics Incorporation, Canada for the electrical signals acquisition. The EMG signals were collected concomitantly to the platform (synchronism. Data were collected in two moments: firstly without tape and immediately after, with the tape. RESULTS: The subject average age was 23.3 years (± 2.8, body mass of 74.4 kg (± 9.4, height of 1.7 m (± 0.4 and BMI of 23.7 kg/m2. The research found statistically significant difference of p = 0.018 when the subjects were using the functional ankle tape, with a decreasing of reaction time in long fibular. CONCLUSION: We believe that this increase is related to the close contact of the functional tape with the ankle cutaneous receptors, increasing the fibular reflex activation, with a consequent proprioceptive gain and hence increasing the subjects' ability to respond to sudden ankle sprains. The study showed decrease in long fibular reaction time of health subjects while using this kind of ankle tape when submitted to a sudden lateral ankle inclination.

    Full Text Available Pendant les deux premières années de la présidence de J. D. Perón (1946-1955, et dans le cadre du processus appelé « démocratisation du bien-être », les questions relatives à l'accès au loisir et au temps libre ont occupé un espace chaque fois plus important. Ainsi, les pratiques sociales et culturelles pendant les périodes de vacances dans les secteurs moyens et ouvriers ont été favorisées au moyen des politiques publiques qui ont conflué avec les initiatives de la société civile. Pendant cette période l'État National a ouvert les canaux qui ont permis l'inclination de ces secteurs sociaux, vers la consommation d'une variété d'activités récréatives. Sur ce rapport, il est intéressant d'analyser quelques unes de ces politiques ainsi que la réception et l'impact qu'elles ont exercé sur ces sujets sociaux. Pour cela nous effectuerons un exercice méthodologique avec une source historique privilégiée: le fonds documentaire « Secrétariat Technique. Première et Seconde Présidence du Général Juan Domingo Perón (1946 - 1955 », un patrimoine documentaire qui résume la réponse - au moyen de lettres du « peuple » à la convocation de l'État devant le second plan Quinquennal.Throughout J.D. Peron’s first two terms in office (1946-1955, against the backdrop the so-called “welfare democratization” process, leisure and free time progressively gained momentum. Vacation habits in the middle and working classes became richer thanks to both public policies and civil initiatives. During this period, the National State not only re-adopted previous programs, but it also opened new channels favoring the entrance of the abovementioned sectors into the recreational-activity market. The purpose of this presentation is to analyze some of these policies, highlighting their reception by, and impact on, the middle and working classes. To this end, a methodological exercise will be carried out on the basis of a privileged source: the archives of the “Secretaría Técnica. Primera y Segunda Presidencia del General Juan Domingo Perón (1946 – 1955”, a collection of documents summarizing the answer –by way of letters– of the populace to the State’s call during the elaboration of the second five-year plan.Durante los años de las dos primeras presidencias de J.

Así, las prácticas vacacionales en los sectores medios y obreros estuvieron fomentadas mediante las políticas públicas que confluyeron con las iniciativas procedentes de la sociedad civil. Durante esta etapa el Estado Nacional, a la vez que retomó tendencias puestas en marcha en etapas previas, abrió los canales que permitieron la inclinación de estos sectores sociales, hacia el consumo de una variedad de actividades recreacionales.

    Future ocean acidification (OA) will affect physiological traits of marine species, with calcifying species being particularly vulnerable. As OA entails high energy demands, particularly during the rapid juvenile growth phase, food supply may play a key role in the response of marine organisms to OA. We experimentally evaluated the role of food supply in modulating physiological responses and biomineralization processes in juveniles of the Chilean scallop, Argopecten purpuratus, that were exposed to control (pH 8.0) and low pH (pH 7.6) conditions using three food supply treatments (high, intermediate, and low). We found that pH and food levels had additive effects on the physiological response of the juvenile scallops. Metabolic rates, shell growth, net calcification, and ingestion rates increased significantly at low pH conditions, independent of food. These physiological responses increased significantly in organisms exposed to intermediate and high levels of food supply. Hence, food supply seems to play a major role modulating organismal response by providing the energetic means to bolster the physiological response of OA stress. On the contrary, the relative expression of chitin synthase, a functional molecule for biomineralization, increased significantly in scallops exposed to low food supply and low pH, which resulted in a thicker periostracum enriched with chitin polysaccharides. Under reduced food and low pH conditions, the adaptive organismal response was to trade-off growth for the expression of biomineralization molecules and altering of the organic composition of shell periostracum, suggesting that the future performance of these calcifiers will depend on the trajectories of both OA and food supply. Thus, incorporating a suite of traits and multiple stressors in future studies of the adaptive organismal response may provide key insights on OA impacts on marine calcifiers.

    2008-01-01

    In this work, we present a novel construction for solving the linear multiuser detection problem using the Gaussian Belief Propagation algorithm. Our algorithm yields an efficient, iterative and distributed implementation of the MMSE detector. We compare our algorithm's performance to a recent result and show an improved memory consumption, reduced computation steps and a reduction in the number of sent messages. We prove that recent work by Montanari et al. is an instance of our general algorithm, providing new convergence results for both algorithms.

    2003-03-01

    Our aim is to illustrate the contribution of MRI to diagnosis of lesions of the lower-limb nerve trunks. We report six patients who had clinical and electrophysiological examination for a peroneal or tibial nerve palsy. MRI of the knee showed in three cases a nonenhancing cystic lesion of the peroneal nerve suggesting an intraneural ganglion cyst, confirmed by histological study in one case. One patient with known neurofibromatosis had an enhancing nodular lesion of the peroneal nerve compatible with a neurofibroma. Two patients had diffuse hypertrophy with high signal on T2-weighted images, without contrast enhancement of the sciatic nerve or its branches. These lesions were compatible with localised hypertrophic neuropathy. In one case, biopsy of the superficial branch of the peroneal nerve showed insignificant axonal degeneration. MRI can provide information about the size and site of the abnormal segment of a nerve before treatment and can be used to distinguish different patterns of focal lesion. (orig.)

    The accessory deep peroneal (ADPN) nerve has been regarded as an anomalous nerve derived from the superficial peroneal nerve or its branch and supplies motor innervations for extensor digitorum brevis (EDB) and sensory innervations for the lateral part of the ankle and foot regions. The EDB is usually innervated exclusively by the deep peroneal nerve, a major branch of the the common peroneal nerve, however, in as many as 28% of patients (with same male/female frequency), one or both of the EDB muscles are (partially or exclusively) innervated by the ADPN nerve. This anomaly appears to be inherited in autosomal dominant fashion with incomplete gene penetrance. ADPN existence is of great clinical and surgical importance, and the aim of this study is to describe a very rare case of coexistence ADPN and anterior tarsal tunnel syndrome. PMID:24399869

  4. Double muscle innervation using end-to-side neurorrhaphy in rats

    Directory of Open Access Journals (Sweden)

    Elisangela Jeronymo Stipp-Brambilla

    Full Text Available CONTEXT AND OBJECTIVE: One of the techniques used for treating facial paralysis is double muscle innervation using end-to-end neurorrhaphy with sectioning of healthy nerves. The aim of this study was to evaluate whether double muscle innervation by means of end-to-side neurorrhaphy could occur, with maintenance of muscle innervation. DESIGN AND SETTING: Experimental study developed at the Experimental Research Center, Faculdade de Medicina de Botucatu, Unesp. METHODS: One hundred rats were allocated to five groups as follows: G1, control group; G2, the peroneal nerve was sectioned; G3, the tibial nerve was transected and the proximal stump was end-to-side sutured to the intact peroneal nerve; G4, 120 days after the G3 surgery, the peroneal nerve was sectioned proximally to the neurorrhaphy; G5, 120 days after the G3 surgery, the peroneal and tibial nerves were sectioned proximally to the neurorrhaphy. RESULTS: One hundred and fifty days after the surgery, G3 did not show any change in tibial muscle weight or muscle fiber diameter, but the axonal fiber diameter in the peroneal nerve distal to the neurorrhaphy had decreased. Although G4 showed atrophy of the cranial tibial muscle 30 days after sectioning the peroneal nerve, the electrophysiological test results and axonal diameter measurement confirmed that muscle reinnervation had occurred. CONCLUSION: These findings suggest that double muscle innervation did not occur through end-to-side neurorrhaphy; the tibial nerve was not able to maintain muscle innervation after the peroneal nerve had been sectioned, although muscle reinnervation was found to have occurred, 30 days after the peroneal nerve had been sectioned.

  5. What Protects Certain Nerves from Stretch Injury?

    The human tibial nerves is less prone to injury following joint arthroplasty compared with the peroneal nerves. Besides the anatomical distribution, other features may confer protection from stretch injury. We therefore examined the size, shape and connective tissue distribution for the two nerves. The tibial and peroneal nerves from each side of nine fresh human cadavers we reharvested mid-thigh. Proximal segments manually stretched 20%-25% were fixed in aldehyde, while the adjacent distal segments were fixed in their natural length. Paraffin sections stained by Masson's trichrome method for connective tissue were examined by light microscopy. Tibial nerves had 2X more fascicles compared with the peroneal, but the axonal content appeared similar. Analysis showed that neither nerve had a significant reduction in cross sectional area of the fascicles following stretch. However, fascicles from stretched tibial nerves become significantly more oval compared with those from unstretched controls and peroneal nerves. Tibial nerves had a greater proportion that was extrafascicular tissue (50-55%) compared with peroneal nerves (38%-42%). This epineurium was typically adipose tissue. Perineurial thickness in both nerves was directly related to fascicular size. Tibial nerves have several unique histological features associated with size, shape and tissue composition compared with the peroneal nerve. We suggest that more fascicles with their tightly bound perineurium and more robust epineurium afford protection against stretch injury. Mechanical studies should clarify how size and shape contribute to nerve protection and/or neurapraxia.

    Adriano Henney speaks to Hannah Coaker, Commissioning Editor. After achieving a PhD in medicine and spending many years in academic research in the field of cardiovascular disease, Adriano Henney was recruited by Zeneca Pharmaceuticals from a British Heart Foundation Senior Fellowship, where he led the exploration of new therapeutic approaches in atherosclerosis, specifically focusing on his research interests in vascular biology. Following the merger with Astra to form AstraZeneca, Henney became responsible for exploring strategic improvements to the company's approaches to pharmaceutical target identification and the reduction of attrition in early development, directing projects across research sites and across functional project teams in the USA, Sweden and the UK. This resulted in the creation of a new multidisciplinary department that focused on pathway mapping, modeling and simulation and supporting projects across research and development, which evolved into the establishment of the practice of systems biology within the company. Here, projects prototyped the application of mechanistic disease-modeling approaches in order to support the discovery of innovative new medicines, such as Iressa®. Since leaving AstraZeneca, Henney has continued his interest in systems biology, synthetic biology and systems medicine through his company, Obsidian Biomedical Consulting Ltd. He now directs a major €50 million German national flagship program – the Virtual Liver Network – which is currently the largest systems biology program in Europe.

    Ulnar and peroneal motor nerve conduction volocities (MNCVs) were measured in 47 children in a dialysis-transplantation program. Mean peroneal MNCV was significantly decreased from normal in children with mild renal failure (serum creatinine concentration, 1.5 to 2.9 mg/dl), whereas ulnar MNCV was significantly decreased only when the serum creatinine value was at least 9 mg/dl. Both ulnar and peroneal MNCVs remained unchanged during long-term hemodialysis or peritoneal dialysis; however, after individual dialyses ulnar MNCV increased. After renal transplantation ulnar MNCV returned to normal within a year and peroneal MNCV within 3 years. Before dialysis was required and during long-term dialysis most plasma magnesium values were elevated; ionized calcium activity was decreased in about 50% of determinations. After transplantation and the concentration of divalent cations rapidly returned to normal. These children differed from adults studied in that (a) there was no correlation between severity of renal failure and MNCV, (b) long-term dialysis did not improve MNCV and (c) peroneal velocities did not recover for 3 years after transplantation.

    Full Text Available The study objective was to assess the effect of functional electrical stimulation (FES applied to the peroneal nerve and thigh muscles on gait performance in subjects with hemiparesis. Participants were 45 subjects (age 57.8 ± 14.8 years with hemiparesis (5.37 ± 5.43 years since diagnosis demonstrating a foot-drop and impaired knee control. Thigh stimulation was applied either to the quadriceps or hamstrings muscles, depending on the dysfunction most affecting gait. Gait was assessed during a two-minute walk test with/without stimulation and with peroneal stimulation alone. A second assessment was conducted after six weeks of daily use. The addition of thigh muscles stimulation to peroneal stimulation significantly enhanced gait velocity measures at the initial and second evaluation. Gait symmetry was enhanced by the dual-channel stimulation only at the initial evaluation, and single-limb stance percentage only at the second assessment. For example, after six weeks, the two-minute gait speed with peroneal stimulation and with the dual channel was 0.66 ± 0.30 m/sec and 0.70 ± 0.31 m/sec, respectively (. In conclusion, dual-channel FES may enhance gait performance in subjects with hemiparesis more than peroneal FES alone.

    Recht, Benjamin

    2009-01-01

    This paper provides the best bounds to date on the number of randomly sampled entries required to reconstruct an unknown low rank matrix. These results improve on prior work by Candes and Recht, Candes and Tao, and Keshavan, Montanari, and Oh. The reconstruction is accomplished by minimizing the nuclear norm, or sum of the singular values, of the hidden matrix subject to agreement with the provided entries. If the underlying matrix satisfies a certain incoherence condition, then the number of entries required is equal to a quadratic logarithmic factor times the number of parameters in the singular value decomposition. The proof of this assertion is short, self contained, and uses very elementary analysis. The novel techniques herein are based on recent work in quantum information theory.

    2009-04-01

    Full Text Available We demonstrate the preparation and characterization of a simplified packed-bed microreactor using an immobilized TEMPO catalyst shown to oxidize primary and secondary alcohols via the biphasic Anelli-Montanari protocol. Oxidations occurred in high yields with great stability over time. We observed that plugs of aqueous oxidant and organic alcohol entered the reactor as plugs but merged into an emulsion on the packed-bed. The emulsion coalesced into larger plugs upon exiting the reactor, leaving the organic product separate from the aqueous by-products. Furthermore, the microreactor oxidized a wide range of alcohols and remained active in excess of 100 trials without showing any loss of catalytic activity.

  12. Performance of a community detection algorithm based on semidefinite programming

    Javanmard, Adel; Ricci-Tersenghi, Federico

    2016-01-01

    The problem of detecting communities in a graph is maybe one the most studied inference problems, given its simplicity and widespread diffusion among several disciplines. A very common benchmark for this problem is the stochastic block model or planted partition problem, where a phase transition takes place in the detection of the planted partition by changing the signal-to-noise ratio. Optimal algorithms for the detection exist which are based on spectral methods, but we show these are extremely sensible to slight modification in the generative model. Recently Javanmard, Montanari and Ricci-Tersenghi (arXiv:1511.08769) have used statistical physics arguments, and numerical simulations to show that finding communities in the stochastic block model via semidefinite programming is quasi optimal. Further, the resulting semidefinite relaxation can be solved efficiently, and is very robust with respect to changes in the generative model. In this paper we study in detail several practical aspects of this new algori...

  13. Tables of experimental branching ratios of Auger-type post collisional ionization of rare gases

    CERN Document Server

    Montanari, C C

    2016-01-01

    When an electron is emitted from a sub-valence shell, a vacancy is created and there is a not-null probability for different post collisional ionization (PCI) processes giving rise to a higher target charge state. It is reasonable to consider that PCI is a time-delayed electron emission and, therefore, independent of the projectile. We include the tables of the branching ratios of $0-6$ post-collisionally emitted electrons after single ionization of Ne, Ar, Kr and Xe in different inner shells. These values have already been employed with good results in previous calculations of multiple ionization of rare gases by electrons, positron, protons, antiprotons and different positive ions (see the text and references therein). These tables and explanation is included in [Montanari C C and Miraglia J E 2014, \\textit{J. Phys. B: At. Mol. Opt. Phys.} {\\bf 45}, 105203].

  14. Information-theoretic thresholds from the cavity method

    Coja-Oghlan, Amin; Perkins, Will; Zdeborova, Lenka

    2016-01-01

    Vindicating a sophisticated but non-rigorous physics approach called the cavity method, we establish a formula for the mutual information in statistical inference problems induced by random graphs. This general result implies the conjecture on the information-theoretic threshold in the disassortative stochastic block model [Decelle et al.: Phys. Rev. E (2011)] and allows us to pinpoint the exact condensation phase transition in random constraint satisfaction problems such as random graph coloring, thereby proving a conjecture from [Krzakala et al.: PNAS (2007)]. As a further application we establish the formula for the mutual information in Low-Density Generator Matrix codes as conjectured in [Montanari: IEEE Transactions on Information Theory (2005)]. The proofs provide a conceptual underpinning of the replica symmetric variant of the cavity method, and we expect that the approach will find many future applications.

    Full Text Available Context (background: In case of high division of the sciatic nerve in the pelvis its, common peroneal component may pierce the Piriformis muscle. This anatomical variant can explain many clinical findings. Aims: Its objective is to report a case of high division of the sciatic nerve in order to contribute towards better anatomical understanding of the gluteal region. Methods and Material: Routine undergraduate dissection of a male cadaver revealed bilateral variation in sciatic nerve. Results: Sciatic nerve is dividing into tibial and common peroneal components in the pelvis. Common peroneal component is piercing through the piriformis muscle. Tibial component is emerging between piriformis and superior gemelli muscle. Conclusions: Sciatic nerve variation can lead to a Piriformis muscle syndrome, inadvertent injury during operations in the gluteal region, failure of sciatic nerve block and/or sciatic neuropathy. The differences in routes of these two nerve components can explain them.

    Objective:To study the effect of local anesthetics on perioperative oxidative stress injury and nerve conduction function in diabetic or non-diabetic patients.Methods:A total of 100 c diabetic patients and 100 non-diabetic patients who received selective surgery under intraspinal block anesthesia were selected as the research subjects, diabetic patients were selected as observation group, non-diabetic patients were selected as control group, serum and urine were collected respectively before and after operation, and reactive oxygen species (ROS), malondialdehyde (MDA), superoxide dismutase (SOD), 8-hydroxy-2 deoxyguanosine (8-OHdG) levels were determined; electromyography was carried out, and the motor nerve conduction velocity of median nerve and common peroneal nerve as well as sensory nerve conduction velocity of median nerve and superficial peroneal nerve were determined.Results:One day before operation and 1 day after operation, serum ROS and MDA levels and urine 8-OHdG levels of observation group were significantly higher than those of control group, and serum SOD levels were significantly lower than those of control group; ROS, MDA, SOD and 8-OHdG levels of observation group before and after operation changed more significantly than those of control group. 1 week after operation, MNCV of median nerve and common peroneal nerve as well as SNCV of median nerve and superficial peroneal nerve of observation group were significantly lower than those before operation, and MNCV of median nerve and common peroneal nerve as well as SNCV of median nerve and superficial peroneal nerve of control group were not significantly different from those before operation.Conclusions: Local anesthetics can cause peripheral nerve conduction function impairment in diabetic patients, and the possible molecular mechanism is that local anesthetics activate perioperative oxidative stress more significantly in diabetic patients than in non-diabetic patients.

    Full Text Available This article proposes reconstructing some fundamental aspects of the political-intellectual disputes by defining what was popular in Colombia and Argentina in the second half of the 20th century. We argue that these disputes led to the birth of two concepts which persist in public debate in both countries: violence in Colombia, and populism in Argentina. Specifically, we look at two events which played a central role: ‘April 9th, Gaitan, gaitanism’ and ‘October 17th, Peron, peronism,’ respectively.

    In this work, a microcontroller-based EMG designed and tested on 40 patients. When the patients are in rest, the fast Fourier transform (FFT) analysis was applied to EMG signals recorded from right leg peroneal region. The histograms are constructed from the results of the FFT analysis. The analysis results shows that the amplitude of fibrillation potential of the muscle fiber of 30 patients measured from peroneal region is low and the duration is short. This is the reason why the motor nerves degenerated and 10 patients were found to be healthy.

    The article describes and analyzes one of the political projects that gained strength in Argentina during the between-war years and remained in place throughout Peronism: government tutelage of mothers and children. It examines how the Dirección de Maternidad e Infancia viewed the mother-child dyad, how this office proposed to address the issue of infant mortality, what type of technical staff was in place, and what limitations were encountered in trying to enforce these ideas. It also looks at what changed and what stayed the same at the office under Peronism.

Puede que aquel nombramiento no haya sido considerado suficientemente, sin embargo, tuvo mucha importancia porque con él se superaba al menos institucionalmente una de las más significadas crisis que el famoso Tribunal tuvo que soportar en el transcurso de su secular trayectoria. Globalmente puede afirmarse que aquella crisis se debía, esencialmente, a las inadecuaciones socio-institucionales que presentaba el diseño original con que fue concebido el Tribunal.

    The emergence of the digital media and computational tools has widened the doors for creativity. The cutting edge in the digital arts and role of new technologies can be explored for the possible creativity. This gives an opportunity to involve arts with technologies to make creative works. The interactive artworks are often installed in the places where multiple people can interact with the installation, which allows the art to achieve its purpose by allowing the people to observe and involve with the installation. The level of engagement of the audience depends on the various factors such as aesthetic satisfaction, how the audience constructs meaning, pleasure and enjoyment. The method to evaluate these experiences is challenging as it depends on integration between the artificial life and real life by means of human computer interaction.

    Full Text Available The aim of this paper is to identify the linguistic writing paradigms underlying the corpus of six grammarians and five writing guidebooks. To achieve this, first, the paper presents three possible concepts of paradigms: morphological, platonic-philosophical and kuhnian-scientific. Second, the study analyses, under the established criteria of empiricism, conceptualization and explanation, important materials written by Adriano da Gama Kury, Celso Luft, Luiz Sacconi, Napoleão Mendes de Almeida, Pasquale Cipro Neto, Paulo Ledur and Editora Abril, Folha de São Paulo, O Estado de São Paulo, O Globo and Zero Hora guidebooks. The conclusion is that there are two patterns in the materials analysed: the prescriptive one of Almeida, Ledur, Sacconi and newspaper and magazine guidebooks and the descriptive one of Cipro Neto, Kury and Luft.

    Full Text Available RESUMEN: Descripción geográfica del territorio de Santo Adriano, cuyos límites coinciden con los del municipio del mismo nombre, en las Asturias centrales: un valle fluvial con zonas de media montaña, perteneciente a la Zona Cantábrica, en el que abunda la "caliza de montaña". Los primeros indicios de poblamiento llegan hasta el paleolítico medio y superior con habitat en varias cuevas, de cuya época se conservan grabados en roca. Está configurado por un sistema de pequeños castros, con sus respectivos "espacios cástrales", que definen bien todo el territorio. La presencia de cultura romana es muy poco relevante. En la documentación medieval más antigua, finales del siglo X, sometida a notables interpolaciones "pelagianas", figuran ya los límites modernos del concejo, con pocas variantes. También se documenta la existencia de habitat troglodítico medieval por hallazgos de algunas, muy pocas, piezas cerámicas. El primer poblamiento altomedieval constaba de varias "villae", localizadas y descritas hasta donde es posible, donadas al monasterio-iglesia de Santo Adriano de Tuñón por Alfonso III yjimena (891. El monasterio fue fundado, asimismo, por estos soberanos, funcionando como el verdadero núcleo articulador de todo el poblamiento antiguo. Se trataba de un territorio vinculado al "Camín de la Mesa", un camino real prerromano, en uso hasta época moderna, que comunicaba Asturias con la meseta. Una localidad, Valdolayés, fue el escenario de una de las batallas más importantes de los astures contra el caudillo musulmán, Munuza, documentada en las Crónicas Asturianas.ABSTRACT: Geographic description of Santo Adriano territory, its frontiers are identical to the municipality with the same name, in Central Asturias: a river valley in mid mountain zones, in the Cantàbric Zone, where the limestone mountain is frequent.

    Full Text Available In this work, we analyzed the case of the Tacuara movement. It
    consisted of a far-right movement which began to act publicly in Argentina in 1958, and underwent a series of splits motivated by confrontations between the conservatives and Catholic appeasers on one side, against groups that sought an alliance with the Peronist movement and like-minded unions after the National Revolution. The latter group was based on an authoritarian, corporatist, antidemocratic and anti-Semitic ideology, but which was also anti-imperialist, populist, and in some occasions, anti-capitalist. Such views converted the Tacuara movement, and particularly the groups which regarded themselves as revolutionaries, into an appropriate viewpoint to discuss the pertinence of the concept of fascism for post-war Latin America, exploring the possibilities of applying to that continent a concept that arose to explain specifically European phenomena.

    En este trabajo analizamos el caso del movimiento Tacuara. Se trata de un grupo de extrema derecha que comenzó a actuar públicamente en Argentina a partir de 1958, mas que llegó a sufrir una serie de divisiones motivadas por el enfrentamiento entre los sectores conservadores y entreguistas católicos por un lado y, por los grupos que, después de la Revolución Nacional, buscaron conectarse con el peronismo, en particular, los sindicatos de esa orientación. Este segundo grupo se fundamentaba en una ideología autoritaria, corporativista, antidemocrática y antisemita; sin embargo, también era antiimperialista, populista y, en algunas ocasiones, anticapitalista.

    2016-01-01

    Objective To identify the factors that could predict the functional outcome in patients with the axonal type of Guillain-Barre syndrome (GBS). Methods Two hundred and two GBS patients admitted to our university hospital between 2003 and 2014 were reviewed retrospectively. We defined a good outcome as being "able to walk independently at 1 month after onset" and a poor outcome as being "unable to walk independently at 1 month after onset". We evaluated the factors that differed between the good and poor outcome groups. Results Twenty-four patients were classified into the acute motor axonal neuropathy type. There was a statistically significant difference between the good and poor outcome groups in terms of the GBS disability score at admission, and GBS disability score and Medical Research Council sum score at 1 month after admission. In an electrophysiologic analysis, the good outcome group showed greater amplitude of median, ulnar, deep peroneal, and posterior tibial nerve compound muscle action potentials (CMAP) and greater amplitude of median, ulnar, and superficial peroneal sensory nerve action potentials (SNAP) than the poor outcome group. Conclusion A lower GBS disability score at admission, high amplitude of median, ulnar, deep peroneal, and posterior tibial CMAPs, and high amplitude of median, ulnar, and superficial peroneal SNAPs were associated with being able to walk at 1 month in patients with axonal GBS.

    Full Text Available The theatrical experience of ‘non-school’ began in the early ‘90’s, in Ravenna, as part of Teatro delle Albe’s work, a company created in 1983 by Marco Martinelli, Ermanna Montanari, Luigi Dadina and Marcella Nonni. From the early years of the new millennium ‘non-school’ started up in various cities, both in Italy and abroad, and took the name of ‘Arrevuoto’ (Revolt in Naples, ‘Capusutta’ (Upside down in Lamezia Terme and ‘Eresia della Felicità a Venezia’ (The Heresy of Happiness in Venice in the city of that name. The ‘bringing to life of the classics’, the work in chorus and the constant attention to otherness and differences contribute to non-school’s style, but form only a part of the complexity of this theatrical work which changes according to which location a performance will take place in and which texts are chosen. The present article looks into some artistic and political aspects of ‘non-school’ and follows its work which connected four Italian cities over the years 2005-2012: Ravenna, Naples, Lamezia Terme and Venice.

    The energy loss straggling of Li and C ions in Al foils of various thicknesses has been measured, within the fractional energy loss limit (∆E/E) ∼ 10-60%. These measurements have been performed using the 15UD Pelletron accelerator facility available at Inter University Accelerator Centre (IUAC), New Delhi, India. The measured straggling values have been compared with the corresponding predicted values adopting popularly used collisional straggling formulations viz Bohr, Lindhard and Scharff, Bethe-Livingston, Titeica. In addition, the experimental data has been compared to the Yang et al. empirical formula and Close Form Model, recently proposed by Montanari et al. The straggling values derived by Titeica theory were found to be in better agreement with the measured values as compared to other straggling formulations. The charge-exchange straggling component has been estimated from the measured data based on Titeica's theory. Finally, a function of the ion effective charge and the energy loss fraction within the target has been fitted to the latter straggling component.

  16. A proof theory for general unification

    CERN Document Server

    Snyder, Wayne

    1991-01-01

    In this monograph we study two generalizations of standard unification, E-unification and higher-order unification, using an abstract approach orig­ inated by Herbrand and developed in the case of standard first-order unifi­ cation by Martelli and Montanari. The formalism presents the unification computation as a set of non-deterministic transformation rules for con­ verting a set of equations to be unified into an explicit representation of a unifier (if such exists). This provides an abstract and mathematically elegant means of analysing the properties of unification in various settings by providing a clean separation of the logical issues from the specification of procedural information, and amounts to a set of 'inference rules' for unification, hence the title of this book. We derive the set of transformations for general E-unification and higher­ order unification from an analysis of the sense in which terms are 'the same' after application of a unifying substitution. In both cases, this results in a...

    Full Text Available Entrepreneurial activity performs an important role in a nation’s economic dynamics. Previous studies argue that institutional factors are correlated with the opening of new businesses, however, the literature is divergent as to the effect of bureaucratic corruption on entrepreneurship. Thus, this article aims to investigate the relationship between entrepreneurship and the incidence of bureaucratic corruption in Brazilian states and its Federal District (Brasilia, for the period of 2000-2008. This study's main hypothesis is that opening a business in Brazilian states is negatively affected by the incidence of corruption. Using a regression method with panel data, we estimated models with pooled data and fixed and random effects. The term entrepreneurship is adopted as the act of starting a new business, as in Say (1816, Mescon and Montanari (1981 and Lachman (1980. To measure corruption, we used the General Index of Corruption for Brazilian states (Boll, 2010, and to represent entrepreneurship, we used firm entry per capita by state. Tests of the Chow (1960, Hausman (1978 e Breusch and Pagan (1979 indicate that the random effects model is more appropriate, and the results indicate a positive correlation between bureaucratic corruption and entrepreneurial activity, contradicting the hypothesis expected and found in previous articles about Brazil.

  18. Fixing convergence of Gaussian belief propagation

    Gaussian belief propagation (GaBP) is an iterative message-passing algorithm for inference in Gaussian graphical models. It is known that when GaBP converges it converges to the correct MAP estimate of the Gaussian random vector and simple sufficient conditions for its convergence have been established. In this paper we develop a double-loop algorithm for forcing convergence of GaBP. Our method computes the correct MAP estimate even in cases where standard GaBP would not have converged. We further extend this construction to compute least-squares solutions of over-constrained linear systems. We believe that our construction has numerous applications, since the GaBP algorithm is linked to solution of linear systems of equations, which is a fundamental problem in computer science and engineering. As a case study, we discuss the linear detection problem. We show that using our new construction, we are able to force convergence of Montanari's linear detection algorithm, in cases where it would originally fail. As a consequence, we are able to increase significantly the number of users that can transmit concurrently.

    We measured brachial and femoral artery flow velocity in eight subjects and peroneal and median muscle sympathetic nerve activity (MSNA) in five subjects during tilt testing to 40 degrees. Tilt caused similar increases in MSNA in the peroneal and median nerves. Tilt caused a fall in femoral artery flow velocity, whereas no changes in flow velocity were seen in the brachial artery. Moreover, with tilt, the increase in the vascular resistance employed (blood pressure/flow velocity) was greater and more sustained in the leg than in the arm. The ratio of the percent increase in vascular resistance in leg to arm was 2.5:1. We suggest that the greater vascular resistance effects in the leg were due to an interaction between sympathetic nerve activity and the myogenic response.

  20. Acute sciatic neuropathy: "Saturday night palsy"

    2005-01-01

    Full Text Available This is a case report of 25-year old, unemployed male, admitted to hospital due to acute onset of the left foot drop, subsequent walking difficulty and numbness of the left calf and foot. Symptoms began after prolonged sleep with previous heroin abuse by sniffing. During neurological examination, mild weakness of knee flexors, moderate weakness of plantar flexors and paralysis of foot dorsiflexors, together with hypesthesia of the left calf, foot and fingers, predominantly in the innervation area of common peroneal nerve on the same side, were observed. The electrophysiologic examination revealed predominant involvement of peroneal division within the sciatic nerve, together with recorded conduction block indicating the compression as possible mechanism of nerve injury. The patient was administered corticosteroid therapy during two months, what resulted in almost complete recovery. The peculiarity of this case report is in the presence of the sciatic nerve "Saturday night palsy" with possible effect of former heroin abuse.

    2016-01-01

    Full Text Available Knowledge of variations of nerves of gluteal region is important for clinicians administering intramuscular injections, for orthopedic surgeons dealing with the hip surgeries and possibly for physiotherapists managing the painful conditions and paralysis of this region. We report multiple variations of the nerves of gluteal region through this article. In the current case, the sciatic nerve was absent. The common peroneal and tibial nerves arose from sacral plexus and reached the gluteal region through greater sciatic foramen above and below piriformis respectively. The common peroneal nerve gave a muscular branch to the gluteus maximus. The inferior gluteal nerve and posterior cutaneous nerve of the thigh arose from a common trunk. The common trunk was formed by three roots. Upper and middle roots arose from sacral plexus and entered gluteal region through greater sciatic foramen respectively above and below piriformis. The lower root arose from the pudendal nerve and joined the common trunk. We discuss the clinical implications of the variations.

  3. Bilateral eventration of sciatic nerve

    2010-12-01

    Full Text Available During routine dissection of a 60 years male cadaver, it was observed that the two divisions of sciatic nerve were separate in the gluteal region on both the sides with the tibial nerve passing below the piriformis and the common peroneal nerve piercing the piriformis muscle. The abnormal passage of the sciatic nerve (SN, the common peroneal nerve (CPN, and the tibial nerve (TN, either through the piriformis or below the superior gemellus may facilitate compression of these nerves. Knowledge of such patterns is also important for surgeons dealing with piriformis syndrome which affects 5-6% of patients referred for the treatment of back and leg pain. A high division may also account for frequent failures reported with the popliteal block. Keywords: eventration, piriformis muscle, piriformis syndrome, sciatic nerve

    Dorsal and ventral divisions of ventral rami of lower lumbar and sacral spinal nerve were found to pass ventral and dorsal to the piriformis muscle respectively. These divisions joined each other below the piriformis muscle to form sciatic nerve. This low formation of sciatic nerve was observed in distal part of left gluteal region of a 50-year-old male cadaver. The sciatic nerve thus formed passed caudally into back of thigh and divided into tibial and common peroneal nerves in the upper part of popliteal fossa. In addition, a communicating nerve from the sciatic nerve was found to join the common peroneal nerve in the popliteal fossa. Such variations may lead to piriformis syndrome or non-discogenic sciatica.

    The purpose of this project is to study and analyse the anatomical variations of the infrapopliteal vessels concerning their branching pattern. A reliable sample of one hundred formalin-fixed adult cadavers was dissected by the Anatomical Laboratory of Athens University. The variations can be classified in the following way: the normal branching of the popliteal artery was present in 90%. The remainder revealed variant branching patterns: hypoplastic or aplastic posterior tibial artery and the pedis arteries arising from the peroneal (3%); hypoplastic or aplastic anterior tibial artery (1.5%); and the dorsalis pedis formed by two equal branches, arising from the peroneal and the anterior tibial artery (2%). The variations were more frequent in females and in short-height individuals. Knowledge of these variations is rather important for any invasive technic concerning lower extremities.

    Understanding of the normal anatomy of the plantar aponeurosis (PA) and familiarity with pathologic conditions are required for an accurate evaluation of the patient with subcalcaneal heel pain. In this study, we evaluated the diagnostic capabilities of magnetic resonance (MR) imaging in the assessment of the PA with close anatomic correlation. Herein, we describe the MR imaging features of plantar fasciitis and fascial rupture in 26 patients. High-spatial-resolution MR imaging was performed in four cadaveric feet, and a prescribed imaging plane was used for depiction of the peroneal component of the PA. MR imaging delineated the anatomy of the PA and perifascial soft tissues. The peroneal component was best visualized in prescribed sagittal oblique images. Perifascial edema was the most common finding of plantar fasciitis, and it was remarkable in those cases with acute fascial rupture. MR imaging reliably delineated the anatomy of the PA and may allow precise localization and definition of the extent of involvement in disease processes.

  7. Heel and foot reconstruction using reverse-flow posterior tibial flap.

    1990-04-01

    Island flaps supplied by the intermuscular cutaneous perforator (IMCP) from a deep vessel, such as the peroneal flap pedicled by IMCP from the peroneal vessel or the anterior tibial flap supplied by IMCP from the anterior tibial vessel, are reported to be useful in reconstructive procedures for soft-tissue defects of the lower leg. However, the posterior tibial flap, pedicled by IMCP from the posterior tibial vessel, has not yet been fully described. The posterior tibial flap can be used either as a normal-flow or as a reverse-flow flap. It is particularly versatile as a reverse-flow flap for reconstruction of soft-tissue defects of the heel and foot. Three reverse-flow posterior tibial flaps were clinically applied, without venous anastomosis, to reconstruct heel and foot defects, and all three survived completely. The operative procedure and its characteristics are described.

We measured the effects of repetitive nerve stimulation on (1) tactile thresholds, (2) performance in an ankle force......-matching and (3) an ankle position-matching task. Additional force-matching experiments were done to compare the effects of transient versus continuous stimulation in 6 subjects and to determine the effects of foot anesthesia using lidocaine in another 6 subjects. The results showed that stimulation decreased...... of transient stimulation on force error were greater when compared to continuous stimulation and lidocaine injection. Position-matching performance was unaffected by peroneal nerve or plantar nerve stimulation. Our results show that cutaneous feedback plays a role in the control of force output at the ankle...

    2005-06-01

    Full Text Available Determination of F-wave latency is a simple and valuable method in evaluating proximal part of peripheral nerves. The aim of this study was to determine the mean minimal peroneal F wave (F min in healthy individuals. A total of 282 individuals were studied. The mean age was 45.6 years. The F min (± SD for 564 peroneal nerves was 47.09 ± 4.51 ms. The F min for the age group of 20-45 and height group of 160-180 cm were 47.63 ± 4.50 and 49.77 ± 3.76, respectively. This study demonstrates that the mean F min of our samples was not significantly different from other important similar studies. Age and particularly height had a major role in determination of F min value and these two parameters must be considered in clinical evaluation of patients.

  10. Retrograde vascularisation of fibula free flap in composite oro-mandibular reconstruction

    Directory of Open Access Journals (Sweden)

    G I Nambi

    2013-01-01

    Full Text Available We present a case of composite oromandibular reconstruction with fibula free flap in which the vascularity to the flap was established in a retrograde direction through the distal end of the peroneal pedicle vessels. The flap was initially designed in such a way so as to anastomose with superior thyroid artery. However after initial good flow, the superior thyroid artery flow became insufficient. Therefore, an attempt was made to vascularise the flap by anastomosing the distal end of peroneal vessels with the facial artery and a tributary of the internal jugular vein so that the flap was perfused in a retrograde direction. This was successful and the retrograde flow was adequate to ensure flap survival. We believe this to be the first successful case of reverse vascular flow reported for composite oromandibular reconstruction with the fibula free flap.

    Full Text Available This paper analyzes the economic impact of Peronism in the Nahuel Huapi region and reviews the material and symbolic aspects of this district, which borders Chile and is associated with both the existing national park in the region and the city of Bariloche. To this end, and in dialogue with the material processes of the period, self-recognition and links to other regions were analyzed. The contribution of this manuscript is its recognition that despite Peronism having been experienced as one of the most significant development shifts in the Nahuel Huapi region, and especially in the town of San Carlos de Bariloche, documents both provide evidence of continuity processes and discuss the existing account of a break.

    Piriformis syndrome is a controversial entrapment neuropathy in which the sciatic nerve is thought to be compressed by the piriformis muscle. Two patients developed severe left sciatic neuropathy after piriformis muscle release. One had a total sciatic nerve lesion, whereas the second had a predominantly high common peroneal nerve lesion. Follow-up studies showed reinnervation of the hamstrings only. We conclude that piriformis muscle surgery may be hazardous and result in devastating sciatic nerve injury.

    2016-08-01

    A previous study using electrical stimulation of the common peroneal nerve (geko™) to activate the venous muscle pump measured blood flow in both the femoral and popliteal veins. Increased blood flow by as much as 60% was demonstrated in the femoral vein. Such an increase is assumed to be as a result of an increase in venous flow from the deep calf veins; however this has yet to be confirmed. The aim of this study was to conduct direct measurements in these deep calf veins to confirm this assumption in healthy individuals. This was a single centre open-label intra-subject healthy volunteer comparison of blood flow in the peroneal, posterior tibial and gastrocnemial veins with and without the geko™ device. The device was applied to 18 volunteers. Peak venous velocity (PV) and ejected volume per individual stimulus (VS) and volume flow (VF) was determined using ultrasound. Peak velocity (PV) increased 216% in the peroneal vein, by 112% in the posterior tibial vein and by 137% in the gastrocnemial vein (P<0.001). Ejected volume per stimulus increased by 113% in the peroneal vein, by 38% in the posterior tibial vein and by 50% in the gastrocnemial vein (P<0.003). Associated volume flows during the muscle contraction were increased by 36%, 25% and 17%, respectively (P=0.05) CONCLUSIONS: This is the first time that neuromuscular electro-stimulation has been shown to be an effective method of increasing flow in the axial deep veins of the calf. Significant increases in velocity and volume flow in response to the electrical stimulus were seen in all three veins studied. Enhancements of both blood velocity and volume flow are key factors in the prevention of venous stasis and ultimately deep vein thrombosis (DVT). Further studies are justified to determine the efficacy of the device in the prevention of DVT.

    Full Text Available OBJECTIVE: Evaluation of diabetic sensorimotor polyneuropathy (DSP is hindered by the need for complex nerve conduction study (NCS protocols and lack of predictive biomarkers. We aimed to determine the performance of single and simple combinations of NCS parameters for identification and future prediction of DSP. MATERIALS AND METHODS: 406 participants (61 with type 1 diabetes and 345 with type 2 diabetes with a broad spectrum of neuropathy, from none to severe, underwent NCS to determine presence or absence of DSP for cross-sectional (concurrent validity analysis. The 109 participants without baseline DSP were re-evaluated for its future onset (predictive validity. Performance of NCS parameters was compared by area under the receiver operating characteristic curve (AROC. RESULTS: At baseline there were 246 (60% Prevalent Cases. After 3.9 years mean follow-up, 25 (23% of the 109 Prevalent Controls that were followed became Incident DSP Cases. Threshold values for peroneal conduction velocity and sural amplitude potential best identified Prevalent Cases (AROC 0.90 and 0.83, sensitivity 80 and 83%, specificity 89 and 72%, respectively. Baseline tibial F-wave latency, peroneal conduction velocity and the sum of three lower limb nerve conduction velocities (sural, peroneal, and tibial best predicted 4-year incidence (AROC 0.79, 0.79, and 0.85; sensitivity 79, 70, and 81%; specificity 63, 74 and 77%, respectively. DISCUSSION: Individual NCS parameters or their simple combinations are valid measures for identification and future prediction of DSP. Further research into the predictive roles of tibial F-wave latencies, peroneal conduction velocity, and sum of conduction velocities as markers of incipient nerve injury is needed to risk-stratify individuals for clinical and research protocols.

    The sense of force is critical in the control of movement and posture. Multiple factors influence our perception of exerted force, including inputs from cutaneous afferents, muscle afferents and central commands. Here, we studied the influence of cutaneous feedback on the control of ankle force output. We used repetitive electrical stimulation of the superficial peroneal (foot dorsum) and medial plantar nerves (foot sole) to disrupt cutaneous afferent input in 8 healthy subjects. We measured the effects of repetitive nerve stimulation on (1) tactile thresholds, (2) performance in an ankle force-matching and (3) an ankle position-matching task. Additional force-matching experiments were done to compare the effects of transient versus continuous stimulation in 6 subjects and to determine the effects of foot anesthesia using lidocaine in another 6 subjects. The results showed that stimulation decreased cutaneous sensory function as evidenced by increased touch threshold. Absolute dorsiflexion force error increased without visual feedback during peroneal nerve stimulation. This was not a general effect of stimulation because force error did not increase during plantar nerve stimulation. The effects of transient stimulation on force error were greater when compared to continuous stimulation and lidocaine injection. Position-matching performance was unaffected by peroneal nerve or plantar nerve stimulation. Our results show that cutaneous feedback plays a role in the control of force output at the ankle joint. Understanding how the nervous system normally uses cutaneous feedback in motor control will help us identify which functional aspects are impaired in aging and neurological diseases.

  16. Hereditary Neuropathy with Liability to Pressure Palsy: A Recurrent and Bilateral Foot Drop Case Report

    2013-01-01

    Full Text Available Hereditary neuropathy with liability to pressure palsy is characterized by acute, painless, recurrent mononeuropathies secondary to minor trauma or compression. A 16-year-old boy had the first episode of right foot drop after minor motorcycle accident. Electromyography revealed conduction block and slowing velocity conduction of the right deep peroneal nerve at the fibular head. After motor rehabilitation, he fully recovered. Six months later he had the second episode of foot drop in the opposite site after prolonged squatting position. Electromyography revealed sensorimotor polyneuropathy of left peroneal, sural, posterior tibial, and deep peroneal nerves and also of ulnar, radial, and median nerves of both upper limbs. Histological examination revealed sensory nerve demyelination and focal thickenings of myelin fibers. The diagnosis of hereditary neuropathy with liability to pressure palsy was confirmed by PMP22 deletion of chromosome 17p11.2. He started motor rehabilitation and avoidance of stressing factors with progressive recovery. After one-year followup, he was completely asymptomatic. Recurrent bilateral foot drop history, “sausage-like” swellings of myelin in histological examination, and the results of electromyography led the authors to consider the diagnosis despite negative family history. The authors highlight this rare disease in pediatric population and the importance of high index of clinical suspicion for its diagnosis.

    Primate evolutionary morphologists have argued that selection for life in a fine branch niche resulted in grasping specializations that are reflected in the hallucal metatarsal (Mt1) morphology of extant "prosimians", while a transition to use of relatively larger, horizontal substrates explains the apparent loss of such characters in anthropoids. Accordingly, these morphological characters-Mt1 torsion, peroneal process length and thickness, and physiological abduction angle-have been used to reconstruct grasping ability and locomotor mode in the earliest fossil primates. Although these characters are prominently featured in debates on the origin and subsequent radiation of Primates, questions remain about their functional significance. This study examines the relationship between these morphological characters of the Mt1 and a novel metric of pedal grasping ability for a large number of extant taxa in a phylogenetic framework. Results indicate greater Mt1 torsion in taxa that engage in hallucal grasping and in those that utilize relatively small substrates more frequently. This study provides evidence that Carpolestes simpsoni has a torsion value more similar to grasping primates than to any scandentian. The results also show that taxa that habitually grasp vertical substrates are distinguished from other taxa in having relatively longer peroneal processes. Furthermore, a longer peroneal process is also correlated with calcaneal elongation, a metric previously found to reflect leaping proclivity. A more refined understanding of the functional associations between Mt1 morphology and behavior in extant primates enhances the potential for using these morphological characters to comprehend primate (locomotor) evolution.

    A 27-year-old man was admitted to our hospital for investigation of severe claudication in his right foot. Based on the findings of magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA), we diagnosed anatomic popliteal artery entrapment syndrome, which was causing a short popliteal artery occlusion. Moreover, a long posterior tibial artery occlusion and a peroneal artery lesion had developed as distal thromboembolic complications of the entrapment. Thus, we planned to perform in situ vein bypass graft for the popliteal occlusion and start thrombolytic treatment for the posterior tibial and peroneal lesions. While contemplating the operation, the patient showed a gradual clinical improvement over the next 2 months. A second MRA showed total arterial recanalization of the right posterior tibial and peroneal arteries, although the popliteal artery was still occluded. Spontaneous lower limb arterial recanalization is a rare phenomenon. To our knowledge, this is the first case of spontaneous arterial recanalization after a distal thromboembolic event caused by popliteal entrapment syndrome.

  19. The "Demetrios": Trotskyists, Peronist Nazis?

    Full Text Available The “Encuadramiento” of Peronist Youth was one of the most important militant groups of boiling political youths during the second half of the 1960s and the first of the 1970s. A political and intellectual experience that was absent in most of the historiography of the period, since mid-2012 have appeared the first studies. The “Demetrios” defined their actions inside of what was called "objective and doctrinal loyalty" to General Peron, thus enabling us to locate them within "orthodox" peronism, on a path similar to the Iron Guard. However, its origins and certain theoretical-political formulations made them receive diferent nicknames that, in the militant jargon, went from the "troskos" to "hitlerites". In this paper we analyze this political career focusing on the ideological aspects. To do this we examined their origins of transition from Trotskyism to Peronism, its peculiar considerations about the nazi phenomenon and its political and ideological location in 1973. That year was a key moment of definitions within the Peronist Youth, which included a debate and a dispute with the revolutionary tendency on the meaning of "national socialism" publicly endorsed by Perón in the preceding years.

    Axial muscles like the trapezius have different reflexive and functional properties. The aim of this study was to analyze the long latency reflexes obtained from the trapezius by the electrical stimulation of upper and lower extremity peripheral nerves. Thirty-one healthy volunteers were included in the study. Surface EMG activity of both trapezius muscles was recorded and averaged after electrical stimulation of the median and peroneal mixed nerves. The recordings were performed during supine and erect posture in nine subjects to evaluate of the effect of postural differences on reflex response. Reflex recordings were also performed in six subjects from some other muscles together with the trapezius by the stimulation of the peroneal nerve. Reflex responses including three components were recorded from the trapezius muscle (unilateral or bilateral) by electrical stimulation of the peroneal nerve. The most stable of them was the second component (23/31) which had a latency of 72.6 ± 7.9 ms for the ipsilateral, and 74.2 ± 8.5 ms for the contralateral trapezius (15/31). For median stimulation, the first component recorded at 32.0 ± 6.7 ms was the most stable (25/31). The second component was more frequently recorded on the contralateral side (14/31). Erect posture increased the amplitude of these components. Upper and lower extremity proprioceptive inputs modulate the EMG activity of the trapezius. This modulation probably related with postural adjustments.

    The Turonian successions of the southern Corbieres comprise three transgressive-regressive cycles in which ammonites occur in three intervals. The lowest comes from the glauconitic basal transgressive unit of the first cycle, and comprises 21 species, including Kamerunoceras douvillei (Pervinquiere, 1907), Kamerunoceras turoniense (d'Orbigny, 1850), Spathites (Jeanrogericeras) revelerianus (Courtiller, 1860), Spathites (Jeanrogericeras) combesi (d'Orbigny, 1856), Mammites nodosoides (Schluter, 1871), Mammites powelli Kennedy, Wright and Hancock, 1987, Fagesia tevestensis (Peron, 1896), Neoptychites cephalotus (Coutiller, 1860), Thomasites rollandi (Thomas and Peron, 1889), Wrightoceras wallsi Reyment, 1954, and Choffaticeras (Choffaticeras) quaasi (Peron, 1904). This is a Lower Turonian assemblage referred to the Mammites nodosoides Zone, although the possibility that elements from the preceding Fagesia catinus Zone are also present cannot be excluded. The fauna from the transgressive glauconitic interval of the succeeding cycle comprises nine species, including Romaniceras (Romaniceras) mexicanum Jones, 1938, Romaniceras (Yubariceras) ornatissimum (Stoliczka, 1864), Pseudotissotia galliennei (d'Orbigny, 1850), Collignoniceras woollgari (Mantell, 1822) sensu lato, Coilopoceras springeri Hyatt, 1903, and Eubostrychoceras (Eubostrychoceras) saxonicum (Schluter, 1872). They indicate the Middle Turonian Romaniceras (R.) mexicanum and R. (Y.) ornatissimum zones. The highest fauna, from the Marnes superieurs de Saint-Louis of the Saint-Louis syncline, is: Subprionocyclus sp. juv., Prionocyclus sp. and Worthoceras cf. rochatianum (d'Orbigny, 1850). The Subprionocyclus are minute individuals that resemble S. bravaisianus (d'Orbigny, 1841), and suggest the presence of the lower Upper Turonian bravaisianus Zone.

    Functional recovery is often unsatisfactory after severe extended nerve defects or proximal nerve trunks injuries repaired by traditional repair methods, as the long regeneration distance for the regenerated axons to reinnervate their original target end-organs. The proximal nerve stump can regenerate with many collaterals that reinnervate the distal stump after peripheral nerve injury, it may be possible to use nearby fewer nerve fibers to repair more nerve fibers at the distal end to shorten the regenerating distance. In this study, the proximal peroneal nerve was used to repair both the distal peroneal and tibial nerve. The number and location of motor neurons in spinal cord as well as functional and morphological recovery were assessed at 2 months, 4 months and 8 months after nerve repair, respectively. Projections from the intact peroneal and tibial nerves were also studied in normal animals. The changes of motor neurons were assessed using the retrograde neurotracers FG and DiI to backlabel motor neurons that regenerate axons into two different pathways. To evaluate the functional recovery, the muscle forces and sciatic function index were examined. The muscles and myelinated axons were assessed using electrophysiology and histology. The results showed that all labeled motor neurons after nerve repair were always confined within the normal peroneal nerve pool and nearly all the distribution of motor neurons labeled via distal different nerves was disorganized as compared to normal group. However, there was a significant decline in the number of double labeled motor neurons and an obvious improvement with respect to the functional and morphological recovery between 2 and 8 months. In addition, the tibial/peroneal motor neuron number ratio at different times was 2.11±0.05, 2.13±0.08, 2.09±0.12, respectively, and was close to normal group (2.21±0.09). Quantitative analysis showed no significant morphological differences between myelinated nerve fibers

    Full Text Available Background. The sciatic nerve, as the terminal branch of the sacral plexus, leaves the pelvis through the greater sciatic foramen beneath the piriform muscle. Afterwards, it separates into the tibial and the common peroneal nerve, most frequently at the level of the upper angle of the popliteal fossa. Higher level of the sciatic nerve division is a relatively frequent phenomenom and it may be the cause of an incomplete block of the sciatic nerve during the popliteal block anesthesia. There is a possibility of different anatomic relations between the sciatic nerve or its terminal branches and the piriform muscle (piriformis syndrome. The aim of this research was to investigate the level of the sciatic nerve division and its relations to the piriform muscle. It was performed on 100 human fetuses (200 lower extremities which were in various gestational periods and of various sex, using microdissection method. Characteristic cases were photographed. Results. Sciatic nerve separated into the tibial and common peroneal nerve in popliteal fossa in 72.5% of the cases (bilaterally in the 66% of the cases. In the remainder of the cases the sciatic nerve division was high (27.5% of the cases in the posteror femoral or in the gluteal region. Sciatic nerve left the pelvis through the infrapiriform foramen in 192 lower extremities (96% of the cases, while in 8 lower extremities (4% of the cases the variable relations between sciatic nerve and piriform muscle were detected. The common peroneal nerve penetrated the piriform muscle and left the pelvis in 5 lower extremities (2.5% of the cases and the tibial nerve in those cases left the pelvis through the infrapiriform foramen. In 3 lower extremities (1.5% of the cases common peroneal nerve left the pelvis through suprapiriform, and the tibial nerve through the infrapiriform foramen. The high terminal division of sciatic nerve (detected in 1/3 of the cases, must be kept in mind during the performing of popliteal

    Regenerative Peripheral Nerve Interfaces (RPNIs) are neurotized muscle grafts intended to produce electromyographic signals suitable for motorized prosthesis control. Two RPNIs producing independent agonist/antagonist signals are required for each control axis; however, it is unknown whether signals from adjacent RPNIs are independent. The purpose of this work was to determine signaling characteristics from two adjacent RPNIs, the first neurotized by a foot dorsi-flexor nerve and the second neurotized by a foot plantar-flexor nerve in a rodent model. Two Control group rats had electrodes implanted onto the soleus (tibial nerve) and extensor digitorum longus (peroneal nerve) muscles in the left hind limb. Two Dual-RPNI group rats had two separate muscles grafted to the left thigh and each implanted with electrodes: the extensor digitorum longus was neurotized with a transected fascicle from the tibial nerve, and the tibialis anterior was implanted with a transected peroneal nerve. Four months post-surgery, rats walked on a treadmill, were videographed, and electromyographic signals were recorded. Amplitude and periodicity of all signals relative to gait period were quantified. To facilitate comparisons across groups, electromyographic signals were expressed as a percent of total stepping cycle activity for each stance and swing gait phase. Independence between peroneal and tibial nerve activations were assessed by statistical comparisons between groups during stance and swing. Electromyographic activity for Control and Dual-RPNI rats displayed alternating activation patterns coinciding with stance and swing. Significant signal amplitude differences between the peroneal and tibial nerves were found in both the Control and Dual-RPNI groups. Non-inferiority tests performed on Dual-RPNI group signal confidence intervals showed that activation was equivalent to the Control group in all but the peroneal RPNI construct during stance. The similar electromyographic activity

Several risk factors have been implicated in lithotomy position-related common peroneal nerve paralysis during operation.Materials and methods: In the present study, 21 young healthy volunteers participated in the investigation of the causes of the paralysis of the common peroneal nerve in the lithotomy position using a knee-crutch/leg-holder; Knee Crutch. We assessed the external pressure applied to the fibular head and medial regions using the Big-Mat pressure-distribution measurement system. Relationships between the peak contact pressure and physical characteristics, such as sex, height, weight, body mass index (BMI, and fibular head circumference, were analyzed.Results: The peak contact pressure to the fibular head region was greater for males than for females. For all subjects, significant positive correlations were observed between the peak contact pressure to the fibular head region and weight, BMI, or fibular head circumference. However, there was no significant difference between the peak contact pressure to the fibular head region and height for any subjects. Moreover, there was no sex-related difference in the peak contact pressure to the fibular medial region, and no significant differences between the peak contact pressure to the fibular medial region and height, weight, BMI, or fibular head circumference.Conclusion: External pressure to the fibular head region is greater for males than for females using a knee-crutch/leg-holder system in the lithotomy position.

    Full Text Available El Pantheon de Adriano es una de las obras más celebradas de la historia de la arquitectura. Han sido muchas las cuestiones que han cautivado a cuantos han entrado en él, pero es la luz la que ha acaparado el mayor protagonismo: una vez despojado el edificio de su originaria carga simbólica, la manifestación de su luz interior parece ser el único fin de este inmenso espacio-luz que tanto ha fascinado a arquitectos, historiadores del arte, pintores y fotógrafos. Parece difícil poder aportar nada nuevo. Consciente de ello, el autor del presente artículo sólo pretende apuntar algunas cuestiones sobre distintos aspectos de la luz en el Pantheon que considera que no han sido aún suficientemente desarrolladas: el por qué de la orientación solar y urbana del templo con respecto al eje norte-sur; la reconstrucción de la secuencia de luz y sombra que debió de darse en el recorrido original de acceso al interior del templo; la interpretación del haz de luz ocular como reminiscencia inmaterial del soporte central de las falsas cúpulas etruscas, convertida en una columna de materia sutil que, sin alcanzar nunca la vertical, incide de manera variada sobre los paramentos que conforman el interior.

    The hadronic energy resolution required for an hadronic operating at lepton collider is at the limits or even exceeds that obtained with traditional techniques. Furthermore, it is a well established fact that the presence of an electromagnetic section in front of an hadron calorimeter, as occurs in the layouts of the majority of detectors operating at a collider, would deteriorate the hadronic energy resolution of the device. The novel $ADRIANO$ technology (\\textit{A Dual-readout Integrally Active Non-segmented Option}), currently under development at Fermilab, overcomes the above limitations by complementing an integrally active calorimeter with the dual-readout technique. Detailed Monte Carlo studies indicate that the energy resolution is in the $25\\%/\\sqrt{E}$ - $38\\%/\\sqrt{E}$ interval with a linear response of the detector up to an energy of 200 GeV. A baseline configuration is chosen with an estimated energy resolution of $\\sigma(E)/E\\approx30\\%/\\sqrt{E}$. Several prototypes have been built by \\textit{T...

They bind strongly to bone matrix and reduce bone loss through inhibition of osteoclast activity. They are classified as nitrogen- and non-nitrogen-containing bisphosphonates (NBPs and NNBPs, respectively. The former inhibit farnesyl diphosphate synthase while the latter induce the production of toxic analogs of adenosine triphosphate. These mechanisms of action are associated with different antifracture efficacy, and NBPs show the most powerful action. Moreover, recent evidence indicates that NBPs can also stimulate osteoblast activity and differentiation. Several randomized control trials have demonstrated that NBPs significantly improve bone mineral density, suppress bone turnover, and reduce the incidence of both vertebral and nonvertebral fragility fractures. Although they are generally considered safe, some side effects are reported (esophagitis, acute phase reaction, hypocalcemia, uveitis, and compliance with therapy is often inadequate. In particular, gastrointestinal discomfort is frequent with the older daily oral administrations and is responsible for a high proportion of discontinuation. The most recent weekly and monthly formulations, and in particular the yearly infusion of zoledronate, significantly improve persistence with treatment, and optimize clinical, densitometric, and antifracture outcomes.Keywords: bisphosphonates, osteoporosis, safety, tolerability, zoledronic acid

    Full Text Available C Randall Lane, Adriano R Tonelli Respiratory Institute, Cleveland Clinic, Cleveland, OH, USA Abstract: Chronic obstructive pulmonary disease (COPD is a leading cause of mortality and morbidity. Lung transplantation is one of the few treatments available for end-stage COPD with the potential to improve survival and quality of life. The selection of candidates and timing of listing present challenges, as COPD tends to progress fairly slowly, and survival after lung transplantation remains limited. Though the natural course of COPD is difficult to predict, the use of assessments of functional status and multivariable indices such as the BODE index can help identify which patients with COPD are at increased risk for mortality, and hence which are more likely to benefit from lung transplantation. Patients with COPD can undergo either single or bilateral lung transplantation. Although many studies suggest better long-term survival with bilateral lung transplant, especially in younger patients, this continues to be debated, and definitive recommendations about this cannot be made. Patients may be more susceptible to particular complications of transplant for COPD, including native lung hyperinflation, and development of lung cancer.

A retrospective study was carried out, analyzing data from 525 children who underwent bilateral medial recti recession, bilateral lateral recti resection, and inferior oblique recession and anteroposition by the same surgeon (AM. Postoperative evaluation included assessment of motor alignment at approximately 3 months, 6 months, 1 year, and 5 years. Statistical analysis was performed with a logistical regression model in which the dependent variable was the presence/absence of reoperation. We found that late surgery (after 3 years of age and a family history of strabismus are associated with a higher risk of reoperation, while some clinical factors, including some classically associated with worst motor outcome as preoperative angle, dissociated vertical deviation, and amblyopia, did not influence the incidence of reoperation in infantile esotropia. Male patients and patients with hyperopia in preoperative examinations have a significantly decreased reoperation rate. Keywords: infantile esotropia, risk factors, reoperation

  15. How to integrate social sciences in hydrological research?

    The integration of interdisciplinary scientific and societal knowledge plays an increasing role in environmental science. Many scholars have long advocated for a joint effort of scientists from different disciplines (interdisciplinarity) to address the problems of the growing pressure on environmental and human systems (Nature, 2015). Such a need was also recognised for the hydrological sciences (HS) e.g. most recently by Vogel et al. (2015). Vibrant new approaches such as "Panta Rhei" (Montanari et al., 2013) and "Socio-Hydrology" (Sivapalan et al., 2012) discuss and propose options for the deeper involvement of hydrologists in socio-economic questions. While there is widespread consensus that coping with the challenges of global change in water resources requires more consideration of human activity, it still remains unclear which roles the social sciences and the humanities (SSH) should assume in this context. Despite the frequent usage of the term "interdisciplinarity" in related discussions, there seems to be a tendency towards assimilation of socio-economic aspects into hydrological research rather than an opening up for interdisciplinary collaboration with social scientists at eye level. The literature, however, remains vague with respect to the concepts of integration and does not allow confirming this assumed tendency. Moreover, the discourse within the hydrological research community on increasing the consideration of societal aspects in hydrological modelling and research is still led by a comparatively small group. In this contribution we highlight the most interesting results of a survey among hydrologists (with 184 respondents). The survey participants do not think that SSH is presently well integrated into hydrological research. They recognize the need for better cooperation between the two disciplines. When asked about ways to improve the status of cooperation, a higher status and acknowledgment of interdisciplinary research by colleagues do not

    The necessity of a more integrated approach in hydrological research has been highlighted by the IAHS scientific decade 2013-2022 "Panta Rhei", dedicated to foster multi-disciplinary research activities on changes in hydrology and society (Montanari, Young et al. 2013). On a similar note, the concept of Socio-Hydrology (Sivapalan, Savenije et al. 2012) suggests a much deeper involvement of hydrologists in socio-economic questions. Despite this general consensus, it remains unclear how such interdisciplinary approaches should be carried out and, in particular, which roles hydrological sciences (HS) and social sciences and the humanities (SSH) should assume. In order to evaluate the opinion of HS on the mutual contributions of HS and SSH to the process of integration, an online survey was prepared by the authors and announced through the newsletters of the International Association of Hydrogeologists (IAH) and the International Association of Hydrological Sciences (IAHS). Two sets of questions offered a choice of potential contributions to interdisciplinary processes of HS and SSH respectively. A third group of questions asked for the status of integration of HS and SSH and if improvements are needed. Finally, participants were asked to rank different options to foster or improve cooperation between natural and social scientists. 141 questionnaires could be used for further analysis. As expected the background of most participants is hydrology, but many also mention more than one discipline. Most participants have their main place of work in Europe. The answers were analysed using Factor and Cluster analysis to reveal potential patterns in the data. The main results from the survey can be summarized like this: The majority of respondents agrees that SSH is not well integrated into hydrological research as yet and most participants see a need for better cooperation. Expectations from hydrologists who should do what in integrative work, reveal that some roles are

  17. Climate change impact studies - how reliable are they?

    2010-05-01

    When two experts estimate the 100-year flood in a small ungauged catchment, chances are that their estimates are very different. When two groups predict the effects of future hydrological changes on stream flow and recharge for the same catchment, the results will hardly be consistent. Yet, climate change impact analyses have become a standard method in our tool box for addressing issues that seem to be of overwhelming concern to the society today. In this paper we argue that impact studies often tend to be overly optimistic about the reliability of their predictions, and overly pessimistic about the effects on society. Just as a medical doctor who, when in doubt, would say that his patient is going to die - to be on the safe side. We will contrast this assessment with our views on the current state of change prediction and outline the opportunities in this area of hydrologic research. Improving the understanding of hydrological processes under the current climate, focusing on why impact studies predict changes rather than on the magnitudes of the change, improving hydrologically-driven uncertainty methods, being more transparent about what we can and cannot predict and being realistic about the role of adaptation measures in the context of water management, we believe, are the cornerstones of more successful climate impact studies. We are truly optimistic that hydrologists will make progress in this important and exciting area of hydrology. Blöschl and A. Montanari (2009) Climate change impacts - throwing the dice? Hydrol.

The nanocarrier was also radiolabeled with 99mTc and tested as a theranostic nanomedicine, ie, it was investigated for both its diagnostic ability in vivo and its therapeutic hyperthermic effects in a standard A431 human tumor cell line. Following radiolabeling with 99mTc, the biodistribution and therapeutic hyperthermic effects of the nanosystem were studied noninvasively in vivo in tumor-bearing mice. A substantial decrease in tumor size correlated with an increase in both nanoparticle concentration and local temperature was achieved, confirming the possibility of using this multifunctional nanosystem as a therapeutic tool for epidermoid carcinoma.

    To examine the association between tibial pilon and calcaneal fracture classification and tendon entrapment or dislocation. After institutional review board approval, we retrospectively reviewed consecutive CT scans with calcaneal or pilon fractures from 5 years at a level 1 trauma center. We categorized calcaneal fractures according to the Sanders classification, and pilon fractures according to the Ruedi and Allgower and the Arbeitsgemeinschaft fuer Osteosynthesefragen-Orthopaedic Trauma Association (AO-OTA) classifications. Ankle tendons were assessed for dislocation or entrapment. Fisher's exact test was used for statistical analysis with significance at p < 0.05. A total of 312 fractures (91 pilon only, 193 calcaneal only, and 14 ankles with ipsilateral pilon and calcaneal fractures) were identified in 273 patients. Twenty-two pilon, 42 calcaneal, and nine combination fractures were associated with 99 occurrences of tendon entrapment or superior peroneal retinacular injury. Such findings were associated with multiple fractures (p = 0.002). Multifragmentary pilon fractures were associated with posterior tibial and flexor digitorum longus tendon entrapment (p < 0.0001 and p = 0.0003 for Ruedi/Allgower and AO-OTA, respectively), and multifragmentary Sanders type 3 or 4 calcaneal fractures were associated with superior peroneal retinacular injury (p = 0.0473) compared to simple fracture patterns. Thirty-nine percent of tendon entrapments or retinacular injuries were prospectively identified, 85 % by musculoskeletal radiologists (p < 0.0001). Approximately 25 % of calcaneal and pilon fractures were retrospectively identified to contain posteromedial tendon entrapment or superior peroneal retinacular injury. Radiologists should meticulously search for such injuries, particularly when analyzing multifragmentary and multiple fractures. (orig.)

    Whether interlimb reflexes emerge only after a severe insult to the human spinal cord is controversial. Here the aim was to examine interlimb reflexes at rest in participants with chronic (>1 year) spinal cord injury (SCI, n = 17) and able-bodied control participants (n = 5). Cutaneous reflexes were evoked by delivering up to 30 trains of stimuli to either the superficial peroneal nerve on the dorsum of the foot or the radial nerve at the wrist (5 pulses, 300 Hz, approximately every 30 s). Participants were instructed to relax the test muscles prior to the delivery of the stimuli. Electromyographic activity was recorded bilaterally in proximal and distal arm and leg muscles. Superficial peroneal nerve stimulation evoked interlimb reflexes in ipsilateral and contralateral arm and contralateral leg muscles of SCI and control participants. Radial nerve stimulation evoked interlimb reflexes in the ipsilateral leg and contralateral arm muscles of control and SCI participants but only contralateral leg muscles of control participants. Interlimb reflexes evoked by superficial peroneal nerve stimulation were longer in latency and duration, and larger in magnitude in SCI participants. Interlimb reflex properties were similar for both SCI and control groups for radial nerve stimulation. Ascending interlimb reflexes tended to occur with a higher incidence in participants with SCI, while descending interlimb reflexes occurred with a higher incidence in able-bodied participants. However, the overall incidence of interlimb reflexes in SCI and neurologically intact participants was similar which suggests that the neural circuitry underlying these reflexes does not necessarily develop after central nervous system injury.

    To determine if a statistical association exists between abnormalities in one ankle tendon group (i.e., peroneal, medial flexor, or Achilles) and those in another. A retrospective analysis of 1.5-T and 3-T MR ankle examinations in 100 patients conducted between November 1, 2011 and April 1, 2012 was performed. The cross-sectional areas and diameters of the ankle tendons-Achilles (ACH), peroneus brevis (PB) and longus (PL), tibialis posterior (TP), flexor digitorum longus (FDL), and flexor hallux longus (FHL)-were measured, and the results were correlated to determine any association with the presence of qualitative abnormalities (tenosynovitis, tendinosis, and tendon tearing). Subjects with larger diameters of the ACH tendon also revealed larger PL, TP, FDL, and FHL tendon diameters and sectional areas. Furthermore, subjects with larger PL tendons generally revealed larger flexor tendons and the same was also true when medial compartment tendons were individually assessed and measurements compared among the three of them. There was a statistically significant association with regard to the presence of tendon abnormalities (tendinosis, tenosynovitis, and tearing) in both the peroneal and medial flexor tendons. The presence of an abnormality in the ACH tendon correlated strongly with increasing diameters and areas of all the other ankle tendons except for the PB tendon. There is an association between quantitative and qualitative abnormalities of one group of tendons when compared with the others with respect to the ACH, medial flexor, and peroneal tendons of the ankle, which is perhaps explained by a retinacular and fascial complex that anatomically connects the three groups.

    Non-specific re-innervation of target organs caused by misdirected axonal growth at the repair site is regarded as one reason for a poor functional outcome after peripheral nerve transsection and repair. This study investigates the rate of aberrant re-innervation and its influence on motor recovery in the rat sciatic nerve using artificial sheets as barrier between tibial and peroneal nerves. The sciatic nerve was transsected and repaired as follows: epineural sutures (A x 6), fascicular repair of tibial and peroneal nerves respectively (B x 8), and the same as in group B, but separating both nerves using an Integra-sheet with silicone (C x 8), or Integra without silicone (D x 8). As control, solely the tibial nerve was transsected and repaired (E x 5). Final investigations after 4 months revealed that in group C, 50% of the Integra-silicone sheets were dislocated. No dislocation was found in group D. Muscle contraction force of the gastrocnemius muscle was significantly higher in group E as compared to all other groups. However although not significant, group D showed a consistently higher muscle contraction force than groups A, B, and C. Histology in groups A, B, and C with dislocated sheets demonstrated multiple axons growing from the tibial to the peroneal nerve and vice versa. In groups D and E, no such axonal growth was visible. These findings were confirmed by a significantly higher rate of specific reinnervation of the soleus muscle using sequential retrograde double labelling technique. Results of this study suggest that an artificial sheet such as Integra bears the potential of preventing aberrant re-innervation between repaired adjacent nerves resulting in improved motor recovery. Clinically, this technique may be of importance for brachial plexus, sciatic nerve, and facial nerve repair.

    Seven healthy volunteers (14 ankles; four males, 3 females) with no history of ankle or foot pathology were placed in a modified beach chair position on an operating table for ankle distraction using a noninvasive ankle distractor. In-line traction of 0 to 225 N (50 lb) in 22.5-N (5-lb) increments was applied to the ankle. A direct lateral radiograph was obtained at each distraction force. The joint space was measured on the lateral radiographs using electronic microcalipers. Surface recordings of the superficial peroneal, deep peroneal dorsal digital cutaneous, and sural nerves were obtained. The ankle joint space increased progressively from an average 3.1 mm with no force applied to an average 4.2 mm with 225 N (50 lb) distraction force applied. The maximum joint distraction averaged 1.3 mm (range, 0.35 to 2.35 mm). The sensory amplitudes were diminished or absent with increasing time and force of distraction. The decreased amplitudes were most marked after 1 hour of distraction with 135 N (30 lb) or greater distraction force. This correlated with symptoms of paresthesias. The superficial and deep peroneal cutaneous nerves were affected to a much greater extent than the sural nerve. The amplitudes quickly returned to normal values with the weight being released from the ankle. The noninvasive ankle distractor safely increased ankle joint space by more than 1 mm. Distraction with 135 N (30 lb) or more for 1 hour is associated with reversible nerve conduction changes. Based on these findings, we recommend using the noninvasive ankle distraction apparatus for ankle arthroscopy, with up to 135 N (30 lb) of traction applied to the foot for up to 1 hour. Greater force, applied for longer periods, is associated with increasing nerve conduction abnormalities.

    The aim of this study was to introduce and assess a new magnetic resonance (MR) technique for selective peripheral nerve imaging, called ''subtraction of unidirectionally encoded images for suppression of heavily isotropic objects'' (SUSHI). Six volunteers underwent diffusion-weighted MR neurography (DW-MRN) of the brachial plexus, and seven volunteers underwent DW-MRN of the sciatic, common peroneal, and tibial nerves at the level of the knee, at 1.5 T. DW-MRN images with SUSHI (DW-MRN{sub SUSHI}) and conventional DW-MRN images (DW-MRN{sub AP}) were displayed using a coronal maximum intensity projection and evaluated by two independent observers regarding signal suppression of lymph nodes, bone marrow, veins, and articular fluids and regarding signal intensity of nerves and ganglia, using five-point grading scales. Scores of DW-MRN{sub SUSHI} were compared to those of DW-MRN{sub AP} using Wilcoxon tests. Suppression of lymph nodes around the brachial plexus and suppression of articular fluids at the level of the knee at DW-MRN{sub SUSHI} was significantly better than that at DW-MRN{sub AP} (P < 0.05). However, overall signal intensity of brachial plexus nerves and ganglia at DW-MRN{sub SUSHI} was significantly lower than that at DW-MRN{sub AP} (P < 0.05). On the other hand, signal intensity of the sciatic, common peroneal, and tibial nerves at the level of the knee at DW-MRN{sub SUSHI} was judged as significantly better than that at DW-MRN{sub AP} (P < 0.05). The SUSHI technique allows more selective visualization of the sciatic, common peroneal, and tibial nerves at the level of the knee but is less useful for brachial plexus imaging because signal intensity of the brachial plexus nerves and ganglia can considerably be decreased.

    Full Text Available The ultrasonographic examination is currently increasingly used in imaging peripheral nerves, serving to supplement the physical examination, electromyography and magnetic resonance imaging. As in the case of other USG imaging studies, the examination of peripheral nerves is non-invasive and well-tolerated by patients. The typical ultrasonographic picture of peripheral nerves as well as the examination technique have been discussed in part I of this article series, following the example of the median nerve. Part II of the series presented the normal anatomy and the technique for examining the peripheral nerves of the upper limb. This part of the article series focuses on the anatomy and technique for examining twelve normal peripheral nerves of the lower extremity: the iliohypogastric and ilioinguinal nerves, the lateral cutaneous nerve of the thigh, the pudendal, sciatic, tibial, sural, medial plantar, lateral plantar, common peroneal, deep peroneal and superficial peroneal nerves. It includes diagrams showing the proper positioning of the sonographic probe, plus USG images of the successively discussed nerves and their surrounding structures. The ultrasonographic appearance of the peripheral nerves in the lower limb is identical to the nerves in the upper limb. However, when imaging the lower extremity, convex probes are more often utilized, to capture deeply-seated nerves. The examination technique, similarly to that used in visualizing the nerves of upper extremity, consists of locating the nerve at a characteristic anatomic reference point and tracking it using the “elevator technique”. All 3 parts of the article series should serve as an introduction to a discussion of peripheral nerve pathologies, which will be presented in subsequent issues of the “Journal of Ultrasonography”.

    The aim was to determine if the treatment of a drop foot by means of an implantable two-channel peroneal nerve stimulator improves health-related quality of life (HRQoL). All subjects were measured at baseline and after a follow-up period of 12 and 26 weeks. Twenty-nine stroke survivors with chronic hemiplegia with drop foot who fulfilled the predefined inclusion and exclusion criteria were included in the present randomized controlled trial. The intervention group received an implantable two-channel peroneal nerve stimulator for correction of their drop foot. The control group continued using their conventional walking device, consisting of an ankle-foot orthosis, orthopedic shoes, or no device. HRQoL was assessed in two different ways: (i) by taking descriptive measures, that is, the Short Form-36 (SF-36; generic measure) and the Disability Impact Profile (DIP; specific measure); and (ii) by obtaining preference-based utilities both measured with the time trade-off (direct way) and by calculating them from the EuroQol (EQ-5D) and SF-36. A significant positive effect of the implantable device was found on the physical functioning domain, the general health domain, and the physical component summary score of the SF-36. For the DIP, a significant improvement was found on the domains mobility, self-care, and psychological status in the intervention group. Regarding the preference-based utility measures, a significant effect was found for the utility index calculated from the EQ-5D. The implantable two-channel peroneal nerve stimulator seems to be efficient to improve HRQoL, mainly the domains related to physical functioning. A relation was present between the utility indexes calculated from the EQ-5D and SF-36.

    Progressive improvement in the ability to treat complete total occlusions in the tibial level arterial circulation have made it possible to revascularize patients with critical limb ischemia. A 59 year old male presented with a complete total occlusion of his anterior tibial artery with distal reconstitution through peroneal artery collaterals. During attempted angioplasty a balloon was retained within the patent portion of the target vessel. Two 3.0 mm drug eluting coronary stents were deployed across the length of the balloon with excellent luminal preservation. Successful CTO revascularization was completed and a strong dorsalis pedis artery pulse was restored following intervention.

    Tenosynovitis refers to an inflammatory condition involving the synovial sheath of a tendon. Stenosing tenosynovitis is a peculiar entity caused by multiple factors, including local anatomy, mechanical factors, and hormonal factors. The main forms include de Quervain tendinopathy; trigger finger (stenosing tenosynovitis involving the flexor digitorum tendons); stenosing tenosynovitis of the extensor carpi ulnaris, extensor carpi radialis, or extensor comunis tendons; stenosing tenosynovitis of the flexor hallucis tendon; and stenosing tenosynovitis of the peroneal tendons. The cardinal finding on ultrasonography is the presence of a thickened retinaculum or pulley that constricts the osseofibrous tunnel through which the tendon runs.

    Full Text Available Emery-Dreifuss muscular dystrophy (EDMD is a hereditary disease. It is characterized by early-onset contractures, slowly progressive weakness, fatigue related to skapulo-humero-peroneal muscle weakness, cardiomyopathy which develops in adulthood and cardiac conduction system block. Cardiac involvement has a prognostic significance in patients with EDMD and even sudden cardiac death may be the first clinical presentation. In this article, an EDMD patient with ischemic stroke clinic who didn’t have regular cardiac follow-up was reported and the importance of the treatment of cardiac diseases which could play a role in ischemic stroke etiology and the implantation of pace-maker was mentioned.

    Bayne, Christopher O; Bishop, Allen T; Shin, Alexander Y

    2014-12-01

    Vascularized free fibula transfer is an attractive option for the treatment of segmental bone defects because of faster union rates, fewer fatigue fractures, rapid hypertrophy, and less resorption compared with nonvascularized bone transfer. It is classically indicated for those patients with segmental bone defects >6 to 8 cm. The presence of several peroneal artery fasciocutaneous perforators also makes the inclusion of a skin paddle possible. Although rare, the surgeon must be aware of possible complications associated with this procedure. A careful operative technique is necessary for obtaining excellent surgical outcomes.

    In a one-year prospective study of 42 elite orienteers, 73 recent injuries (1.7 per runner per year) were found. Acute injuries totalled 52% and 48% were due to overuse. Ankle sprains made up 37% of acute injuries while the remaining were mainly contusions caused by falls or bumps against branches or rocks. Medial shin pain, Achilles peritendinitis, peroneal tenosynovitis and iliotibial band friction syndrome were the most frequent overuse injuries. All overuse injuries were located in the lower extremity while 18% of acute injuries was located elsewhere. Acute injuries were most frequent in the competitive season while overuse injuries occurred most often during the continuous training period.

    There is a high potential for disability following calcaneal fracture. This potential exists whether a patient is treated with conservative or operative management. Subfibular impingement and irritation of the peroneal tendon and sural nerve may also be present. Posttraumatic arthritis of the subtalar joint can occur. In patients with symptomatic calcaneal malunion, systematic evaluation is required to determine the source of pain. Nonsurgical treatment may be effective. One surgical treatment option is subtalar distraction arthrodesis. High rates of successful arthrodesis and patient satisfaction have been reported with this surgical option in correctly selected patients. Published by Elsevier Inc.

    Tarsal coalition is abnormal fusion of two or more tarsal bones. The union may be fibrous, cartilaginous, or osseous and can be congenital or acquired in response to infection, articular disorders, trauma, or surgery. We report a case of fibrous talocalcaneal coalition in a 15-year-old boy in whom bone scintigraphy employing pinhole lateral views confirmed the clinical diagnosis when plain radiographs showed minimal changes and computed tomography was equivocal. The diagnosis of symptomatic tarsal coalition is important in that it is a common remediable cause of peroneal spastic flat foot, a frequently encountered condition. Scintigraphy provides important information about the presence and localization of this condition. (orig.). With 3 figs.

    Posterior tarsal tunnel syndrome is the result of compression of the posterior tibial nerve. Anterior tarsal tunnel syndrome (entrapment of the deep peroneal nerve) typically presents with pain radiating to the first dorsal web space. Distal tarsal tunnel syndrome results from entrapment of the first branch of the lateral plantar nerve and is often misdiagnosed initially as plantar fasciitis. Medial plantar nerve compression is seen most often in running athletes, typically with pain radiating to the medial arch. Morton neuroma is often seen in athletes who place their metatarsal arches repetitively in excessive hyperextension.

    In order to control neural prosthetics by recording signals from peripheral nerves with the required specificity, high density electrode arrays that can be easily implanted on very small peripheral nerves (50μm-500μm) are needed. Interfacing with these small nerves is surgically challenging due to their size and fragile nature. To address this problem, a Flexible MicroChannel Electrode Array for interfacing with small diameter peripheral nerves and nerve fascicles was developed. The electrochemical characterization and electrophysiological recordings from the common peroneal nerve of a rat are presented along with demonstration of the surgical ease-of-use of the array.

  12. Editorial Commentary: Is Medial-Side Repair Indicated in the Treatment of Multiligament Knee Injuries?

    Science.gov (United States)

    Marx, Robert G

    2016-09-01

    Multiligament knee injuries are heterogenous and demand individualized treatment. In addition to the complexity of the injury, factors such as the timing and type of surgery are also crucial to patient outcomes. In a case series, patients who underwent medial-side repair had inferior patient-reported outcomes compared with those who had medial reconstruction or lateral surgery. Interestingly, patients with common peroneal nerve injury did not have inferior outcomes, probably because of the lack of sensitivity of rating scales to measure nerve-related disability. In view of the complexity and heterogeneity of these injuries, the above-mentioned findings may not be generalizable to all patients.

    Full Text Available One of the most singular characteristics of peronism is the originality of holding within it a double charismatic leadership complementary to each other. The quintessential paradigm corresponds to Perón and Eva Perón, but there were other cases, more modest, that have served to cement the argentine political culture: the marriage at power. Those first ladies redefined its role, and built spaces of power and influence in government. In this paper I analyze the role of Elena Caporale de Mercante and her new political role as wife of the most important governor who had the first Peronist government.

    Full Text Available The rat sciatic nerve is composed by the L4, L5 and L6 lumbar spinal nerves. However, the contribution in myelinated fibers originating from these nerves along this nervous trunk has not yet been defined. In the present study, the L4, L5 and L4-L5 spinal nerves were selectively transected. After one week the sciatic, tibial, sural and peroneal nerves were dissected. These samples were fixed and processed for optical microscopy, and both degenerated and normal myelinated fibers were counted in toluidine blue-stained semi-thin sections. L4 contributed with myelinated fibers mainly to the peroneal nerve, and L5 to the sciatic, tibial and sural nerves. In general, the contribution of L6 was smaller and variable along the nervous trunk in comparison to the other two spinal branches. Our results give key information for further studies looking to correlate the contribution of spinal nerves making part of the sciatic nerve and its main branches with hind limb function. El nervio ciático de la rata está formado por los nervios espinales (ne lumbares L4, L5 y L6. Sin embargo, aún no se ha definido el aporte en fibras mielínicas de estos nervios espinales a lo largo del tronco nervioso. En este estudio se transectaron selectivamente los NE L4, L5 y L4-L5. Luego de una semana se disecaron los nervios ciático, tibial, sural y peroneal. Estas muestras se fijaron y procesaron para microscopía óptica y a partir de cortes coloreados con azul de toluidina se contaron las fibras mielínicas degeneradas y normales. L4 contribuyó con fibras mielínicas principalmente al nervio peroneal y L5 a los nervios ciático, tibial y sural. En general, el aporte de L6 fue menor y variable a lo largo del tronco nervioso comparado con las otras dos ramas espinales. Nuestros resultados brindan información valiosa para posteriores estudios que busquen correlacionar la contribución de los nervios espinales que componen el ciático y sus ramas principales con la funci

    Full Text Available Portugal logró construir un imperio colonial en África tan notable como desajustado a las aparentes capacidades del país, y eso fue gracias a una difícil combinación de factores endógenos y exógenos, un éxito que llevó a que los dirigentes lusos confiriesen al Ultramar un papel ideológico capital. Sin embargo, tras la Segunda Guerra Mundial los factores externos que habían favorecido la materialización del Imperio desaparecen, y en este nuevo contexto marcado por la Guerra Fría y la ola descolonizadora, Portugal es incapaz de contemporizar sus relaciones con las colonias. El temor a que la pérdida de los territorios extraeuropeos acabase también con el Régimen, además de otros factores, determinó la imposibilidad de que el Gobierno aceptase revisar sustancialmente su política inmovilista, obligándose a sostenerla en circunstancias internacionales y nacionales extremadamente difíciles, especialmente a partir de 1961. A pesar de la evidente imposibilidad de mantener la soberanía en Ultramar por la fuerza en ese contexto, para buena parte de la cúpula del Estado Novo cualquier alternativa que pusiese en cuestión la «unidad pluricontinental de Portugal y sus provincias ultramarinas» era inaceptable, al ser la piedra angular que sostenía el mito del «caso único» del colonialismo portugués y por consiguiente la justificación de su continuidad, siendo además el dogma que impedía una discusión interior abierta y perniciosa sobre el futuro de las colonias — obviamente junto a la propia naturaleza antidemocrática del Régimen. Por esa razón, el único camino posible era el de la guerra, complementada con algunas reformas administrativas, económicas y sociales que ejecutaría Adriano Moreira, y que no pudieron ser otra cosa que una certificación de los estrechos límites en los que el Portugal de Salazar podía moverse.Portugal managed to build a colonial empire in Africa which was as remarkable as out of proportion

This study aims to define alexithymia's connections with shame, trauma, dissociation, and body image disorders.Methods: We administered the Dissociative Experience Scale-II, Trauma Symptom Inventory, Experience of Shame Scale, Toronto Alexithymia Scale-20, and Body Uneasiness Test questionnaires to 143 ED subjects. Extensive statistical analyses were performed.Results: The subjects showed higher scores on alexithymia, shame, dissociation, and traumatic feelings scales than the nonclinical population. These aspects are linked with each other in a statistically significant way. Partial correlations highlighted that feelings of shame are correlated to body dissatisfaction, irrespective of trauma or depressed mood. Multiple regression analysis demonstrates that shame (anorexic patients and perceived traumatic conditions (bulimic and ED not otherwise specified are associated with adverse image disorders.Conclusion: Shame seems to hold a central role in the perception of an adverse self-image. Alexithymia may be interpreted as being a consequence of previous unelaborated traumatic experiences and feelings of shame, and it could therefore be conceptualized as a maladaptive–reactive construct.Keywords: eating disorders, trauma, alexithymia, shame, body image

    Full Text Available Como es bien sabido, en su Suma teológica Tomás de Aquino defiende desde una perspectiva aristotélica la naturaleza científica de la sacra doctrina, proponiéndola como una ciencia subalterna al conocimiento que Dios tiene de sí mismo.  La interpretación de Tomás en torno a la doctrina aristotélica de la ciencia le permite proponer que las conclusiones de la sacra doctrina se reducen a los artículos de la fe como a sus primeros principios.  Lo que no es bien sabido, sin embargo, es que Tomás en otros textos cambia su postura sobre el modo en que la sacra doctrina llena los requisitos para ser ciencia.  Esto ha sido puesto en evidencia en parte por algunas ediciones críticas recientes, como la de la Lectura Romana, realizada por Boyle, y especialmente la del prólogo al Comentario a las Sentencias, por Adriano Oliva.  Si bien los artículos de la fe son evidentes en sí mismos (per se, estos textos, vistos cronológicamente, demuestran que a través de su carrera Tomás vacila en reconocer que desde nuestra perspectiva (quoad nos los artículos no son evidentes ni demostrables, sino que son objetos de fe religiosa.  A través de estos textos Tomás progresivamente admite que existe una imperfección en el modo en que la conocemos en esta vida (in via; por tanto, la sacra doctrina en cierto modo se queda corta de la ratio perfecta de ciencia, al menos quoad nos.

  9. Diálogos em delay:especulações em torno de uma temporalidade outra do encontro pedagógico

    Directory of Open Access Journals (Sweden)

    Julio Groppa Aquino

    Full Text Available Resumo A fim de conjecturar um plano ético-político expansivo capaz de fomentar uma atitude eminentemente crítica ante o presente educacional, o texto que ora se apresenta organiza-se segundo três patamares argumentativos articulados. No primeiro deles, debruçamo-nos sobre o romance Memórias de Adriano e, em especial, sobre as reflexões de Marguerite Yourcenar acerca do método de composição da obra e de seu modo particular de endereçamento ao passado. Em seguida, por meio de uma espécie de jogo de contraste com o ponto de vista da escritora, são trazidos à baila alguns marcos do legado teórico foucaultiano, especialmente no que se refere aos jogos cruzados entre presente, história e verdade. Tratou-se, assim, de criar uma ambiência argumentativa assentada nas noções de regimes de verdade, de história genealógica e de ontologia do presente. As discussões finais do texto dedicam-se a focalizar, a par da própria experiência de Michel Foucault como professor, as duas tópicas principais do percurso ulterior do pensador − o cuidado de si e a parrhesía −, tendo em vista suas possíveis implicações pedagógicas. Com isso, almejou-se perspectivar uma mirada sobre o encontro pedagógico que, ao lhe conferir certa potência ético-estilística, reclama um regime de tempo diverso nas transações que aí tomam lugar.

    1-Bromopropane (1-BP) has recently become known as an alternative cleaning material with less damage to the ozone layer. However, its toxicity is not fully evaluated. This study was designed to investigate the repeated inhalation toxicity of 1-BP on the nervous systems in Sprague-Dawley rats. The experiment was done by repeated exposure of the rats to 0, 200, 500, and 1250 ppm for 6 h per day, 5 days a week, for 13 weeks, respectively. Morphologic studies were done for the central nervous system, sacral and peroneal nerves. The serial sections of the brain and spinal cord of 1-BP inhalation groups revealed no pathological features either in the gray or white matter. The nerve fiber teasing, light and electron microscopic studies of the sacral and peroneal nerve fibers showed no significant difference between 1-BP inhalation groups and the control group. From these results, it is concluded that the nervous system is histologically resistant to the repeated inhalation of 1-BP up to 1250 ppm for 13 weeks. Experiments with higher concentrations of 1-BP and the functional studies are necessary to clarify the 1-BP toxicity.

    Full Text Available A group of patients with Bell's palsy were studied in order to disclose the presence of subclinical peripheral nerve involvement. 20 patients, 8 male and 12 female, with recent Bell's palsy as their unique disease were examined, in all cases other causes of polyneuropathy were ruled out. Patients were investigated with CSF examination, facial nerve latencies in the affected and in the sound sides, and maximal motor nerve conduction velocities, as well as motor terminal latencies from the right median and peroneal nerves. CSF laboratory examination was normal in all cases. Facial nerve latencies were abnormal in all patients in the affected side, and they differed significantly from those of control group in the clinically sound side. Half of the patients showed abnormal values in the maximal motor nerve conduction velocities and motor terminal latencies of the right median and peroneal nerves. These results agree with previous reports which have pointed out that other cranial nerves may be affected in Bell's palsy. However, we have found a higher frequency of peripheral nerve involvement in this entity. These findings, support the hypothesis that in some patients Bell's palsy is the component of a more widespread disease, affecting other cranial and peripheral nerves.

    Full Text Available More than a regime that stormed to Argentina in the 1940s, Peronism is configured as a system of complex ideas and exceptional, a identification (as defined by Beatriz SARLO. This article focuses on the brightest stage og the Justicialism (another name for the period that was Juan Domingo Perón as its greatest exponent, the First Peronism (1946-1955 - and the construction of a policy of spreading the so-called Social Tourism, while one arm of a larger project carried forward by the powerful Central Office of Information (SI, in Spanish. This strategy was fundamentally based on the production and dissemination of posters. On the other hand, the study shows similarities and differences in this field to other regimes of the first half of the 20th century (Salazarism, Francoism, Fascism, Nazism, Stalinism and New Deal. And it shows how the vision of Michel FOUCAULT about the Disciplinary Power was largely present in the peronist Social Tourism.

Signs of diabetic polyneuropathy (DPNP were revealed in 87.5 percent (n = 28 of patients. Duration of diabetes in patients with DPNP varied from 1 to 30 years (in average, 11.0 ± 6.4 years. Subjective (NSS scale and objective assessment (NDS scale of neuropathy symptoms, as well as the nerve conduction studies of the peroneal, tibial, and sural nerves were performed twice, on the 15–16 and 32–33 weeks of pregnancy.Results. Increase in subjective and objective symptoms of polyneuropathy along the pregnancy according to NSS and NDS scales (р < 0.05, as well as significant decrease of CMAP and SNAP amplitudes (р < 0.05 in the second half of pregnancy, indicating the progression of the DPNP. The most frequent pathological changes were observed in the peroneal and sural nerves.Conclusions. Pregnancy has an adverse effect on the course of the DPNP contributing to the axonal damage of peripheral nerves, progression of neurological impairment and aggravation of subjective neuropathic symptoms.

  14. Bilateral high division of sciatic nerve

    Full Text Available Sciatic nerve is the thickest nerve in the body formed by the sacral plexus from L4 to S3 in the lesser pelvis. It emerges through the greater sciatic foramen below the piriformis and enter the gluteal region. Then the nerve passes on the back of the thigh and at the level of superior angle of popliteal fossa it terminates by dividing into tibial and common peroneal nerve. The knowledge of anatomical variations in the division of nerve is important for various surgical and anaesthetic procedures. During routine dissection in the department of anatomy, Mysore Medical College and Research Institute, Mysore, a rare bilateral high division of sciatic nerve was observed in a female cadaver aged about 40 years. In the present case there was bilateral high division of sciatic nerve. The nerve was seen dividing into two branches before it emerges through the greater sciatic foramen. The tibial nerve was entering the gluteal region below the piriformis muscle and common peroneal nerve was entering by piercing the piriformis. The knowledge of this variation is important as the nerve may get compressed with surrounding anatomical structures resulting in non discogenic sciatica. The awareness of variations is important for surgeons during various procedures like fracture, posterior dislocation of hip joint and hip joint replacement. The anatomical variations are important during deep intramuscular injections in gluteal region and also for anaesthetists during sciatic nerve block. [Int J Res Med Sci 2014; 2(4.000: 1785-1787

    Full Text Available Abstract Background We provided clinical and electrical descriptions of the piriformis syndrome, contributing to better understanding of the pathogenesis and further diagnostic criteria. Methods Between 3550 patients complaining of sciatica, we concluded 26 cases of piriformis syndrome, 15 females, 11 males, mean age 35.37 year-old. We operated 9 patients, 2 to 19 years after the onset of symptoms, 5 had piriformis steroids injection. A dorsolumbar MRI were performed in all cases and a pelvic MRI in 7 patients. The electro-diagnostic test was performed in 13 cases, between them the H reflex of the peroneal nerve was tested 7 times. Results After a followup 1 to 11 years, for the 17 non operated patients, 3 patients responded to conservative treatment. 6 of the operated had an excellent result, 2 residual minor pain and one failed. 3 new anatomical observations were described with atypical compression of the sciatic nerve by the piriformis muscle. Conclusion While the H reflex test of the tibial nerve did not give common satisfaction in the literature for diagnosis, the H reflex of the peroneal nerve should be given more importance, because it demonstrated in our study more specific sign, with six clinical criteria it contributed to improve the method of diagnosis. The cause of this particular syndrome does not only depend on the relation sciatic nerve-piriformis muscle, but the environmental conditions should be considered with the series of the anatomical anomalies to explain the real cause of this pain.

    Objective:To analyze the correlation of serum homocysteine metabolism and oxidative stress level with peripheral nerve damage in patients with Parkinson's disease.Methods:A total of 58 patients with Parkinson's disease and 67 normal human beings were included in the study, levels of plasma homocysteine (Hcy) as well as superoxide dismutase (SOD), GSH, malondialdehyde (MDA) and other oxidative stress indexes were detected, and common peroneal nerve motor conduction velocity (MCV), latent period (LP) and amplitude (Amp) were determined.Results: Serum Hcy level of observation group was higher than that of control group while folic acid and vitamin B6 levels were lower than those of control group; serum oxidative indexes LHP, H2O2, AOPP and MDA levels were higher than those of control group while antioxidant indexes SOD T, SOD Mn, SOD Cu-Zn, GSH-PX, T-AOC and CAT levels were lower than those of control group; common peroneal nerve MCV and Amp values were lower than those of control group while LP value was higher than that of control group. Peripheral nerve damage parameter values in patients with Parkinson's disease were directly correlated with serum levels of Hcy metabolism indexes and oxidative stress indexes. Conclusions: Peripheral nerve damage in patients with Parkinson's disease is associated with hyperhomocysteinemia and oxidative stress disorder, and intervention in serum levels of Hcy and oxidative stress indexes is expected to become a new way for treatment of Parkinson's disease.

  18. VARIATIONS OF SCIATIC NERVE BIFURCATION IN DISSECTED CADAVERES FROM ETHIOPIA AND THEIR CLINICAL IMPLICATION: A CASE REPORT

    Directory of Open Access Journals (Sweden)

    Peter Etim Ekanem

    2015-09-01

    Full Text Available Background: The tibial and common peroneal nerves are dorsal and ventral divisions of the ventral rami of L4 to S3 of the lumbosacral plexus that join to form the sciatic nerve. The two nerves are structurally separate and supply the posterior compartment of the thigh, the leg and the foot. The point of bifurcation or separation of the sciatic nerve into tibial and common peroneal nerve varies. The common site is at the junction of the middle and lower third of the back of the thigh, near the apex of the popliteal fossa, but division may occur at any point above this. It may also rarely occur below it. The variations in the bifurcation of the sciatic nerve have clinical implications. They may result in nerve injury during deep intramuscular injections in the gluteal region, sciatica, piriformis syndrome etc. This study is to report the variations of the bifurcation in the sciatic nerve found in the cadaveres from Ethiopia, and discuss the clinical implications of such variations. Conclusion: We conclude from this study that the bifurcation of the sciatic nerve could occur high up in the gluteal region in relation to the piriformis muscle and may present clinical challenges in patient management

    2013-01-01

    Full Text Available Background: The sciatic nerve is the large stand thickest branch of lumbosacral plexus. It has a long course in the pelvic cavity and in the lower extremity. It separates into its two branches, the tibial and common peroneal nerves outside the pelvis. But the division can occur at any level from the sacral plexus to the inferior part of the popliteal fossa. These anatomical variations in division may cause nerve compression resulting in sciatica, piriformis syndrome, and coccygodynia. Aim: The aim of this study is to observe the variations in division of sciatic nerve as compared to known facts. Methods: The study was performed on cadavers. The inferior extremities of 45 cadavers were examined and variations of division of sciatic nerve were noted and classified. Results: The highest incidence of sciatic nerve variation was observed in its termination. In 11.11% of cases the sciatic nerve was found to be divided in the gluteal region. In 11.11%specimens, the common peroneal nerve pierced the piriformis muscle. Conclusion: The higher division of sciatic nerve can result in the involvement of only one out of the two divisions for the sciatic neuropathy. It is important to consider the higher divisions while performing opliteal block anaesthesia.

    Stimulation of the sural nerve of healthy subjects induced short latency inhibition in the ipsilateral tibialis anterior muscle and facilitation in peroneal muscle. We examined lower limb muscle responses after stimulation of the sural nerve in 19 patients with hemiplegia caused by cerebro-vascular disease and compared them with the control responses. The sural nerve was stimulated electrically (3 or 5 square wave pulses of 0.5 ms repeated at 250 Hz) during weak tonic contraction. Stimulation was triggered to average the rectified surface electromyography (EMG) of the test muscle. Usually 100 - 200 sweeps were averaged. After stimulation, the tibialis anterior muscle on the affected side of the hemiplegic patients showed the patterns of inhibition, facilitation, and no response, whereas all responses on the unaffected side, except those of one patient, were inhibition. The peroneal muscle on both sides showed only facilitation as in the controls. Abnormal responses of the tibialis anterior muscle on the affected side were present in many patients who had the Babinski sign. Abnormal responses in the tibialis anterior muscle of the affected side may have been due to contributions by disinhibition of the flexor reflex, late-recruited motor units or both.

    Injuries to the peroneal tendons are relatively common worldwide but tendon rupture without significant trauma is uncommon. Ankle mechanics can be seriously affected by disruption of one or both of the peroneal tendons although complete rupture can also remain asymptomatic. Accessory ossicles are sesamoid bones and are common findings in routine radiology of the foot and ankle. Although in the vast majority these ''os'' are normal variants of anatomy, they can lead to painful syndromes and suffer fractures and even undergo degenerative changes in response to overuse and trauma. Although similar syndromes have been discussed in the surgical literature, there is a lack of literature describing the use of modern imaging in the accurate diagnosis and its subsequent assistance towards appropriate management of os peroneum friction syndrome complicated by sesamoid fatigue syndrome. This article presents the plain film, sonographic and magnetic resonance imaging findings in a case of os peroneum friction syndrome complicated by a sesamoid fatigue fracture as well as reviewing the pertinent literature.

    The aim of tis report is to describe the effects of a dual-channel functional electrical stimulation (FES) system applied daily as an orthotic device to the dorsiflexors and hamstrings muscles in a subject with chronic hemiparesis. Prior to the application of FES, the patient's gait was characterized by a footdrop and knee hyperextension during stance. measurements of gait performance were collected before FES application, after a conditioning period of six weeks, and following ten months of daily use. Outcomes included lower limb kinematics and temporal gait measures. The kinematic assessments indicated significant benefits for gait with the dorsiflexors and hamstrings FES, as compared to no stimulation and peroneal FES alone. In addition ot improved ankle control, knee hyperextension was reduced during stance, and the self-selected comfortable gait velocity increased following ten months of daily use. The results of this report suggest that dual-channel FES for the dorsiflexors and hamstrings muscles may affect ankle and knee control beyond that witch can be attributed to peroneal stimulation alone. The positive effects observed in this case study point to the potential of dual-channel FES as a viable treatment options in the rehabilitation of patients with similar impairments.

    Full Text Available The primary objectives of this study were to evaluate contractile and non-contractile content of lower leg muscles of boys with Duchenne muscular dystrophy (DMD and determine the relationships between non-contractile content and functional abilities.Lower leg muscles of thirty-two boys with DMD and sixteen age matched unaffected controls were imaged. Non-contractile content, contractile cross sectional area and non-contractile cross sectional area of lower leg muscles (tibialis anterior, extensor digitorum longus, peroneal, medial gastrocnemius and soleus were assessed by magnetic resonance imaging (MRI. Muscle strength, timed functional tests and the Brooke lower extremity score were also assessed.Non-contractile content of lower leg muscles (peroneal, medial gastrocnemius, and soleus was significantly greater than control group (p<0.05. Non-contractile content of lower leg muscles correlated with Brooke score (rs = 0.64-0.84 and 30 feet walk (rs = 0.66-0.80. Dorsiflexor (DF and plantarflexor (PF specific torque was significantly different between the groups.Overall, non-contractile content of the lower leg muscles was greater in DMD than controls. Furthermore, there was an age dependent increase in contractile content in the medial gastrocnemius of boys with DMD. The findings of this study suggest that T1 weighted MR images can be used to monitor disease progression and provide a quantitative estimate of contractile and non-contractile content of tissue in children with DMD.

  4. Interaction of science and diplomacy: Latin American, the United States and nuclear energy, 1945-1955

    Nuclear programs in Argentina and Brazil can be traced to August 1945 when their scientific communities articulated responses to the atomic bombings of Japan. They culminated in attempts to develop independent nuclear programs, sharply opposed by the United States, during the nationalist governments of Juan Peron and Getulio Vargas. This dissertation, based on primary sources from the three nations, analyzes these programs and the American responses. Latin America entered the nuclear age attempting to control natural resources, to improve scientific establishments, and to appraise Latin American-United States relations. Despite some clear warnings about nuclear dangers, the new form of energy was seen as the solution to industrial problems, poverty, and outside political interference. International opposition, which may have included nuclear threats from the United States, blocked Argentina's first attempt in 1947. After 1948, Peron wanted a nuclear program for cheap energy and prestige. The qualifications of the Brazilian scientists gave more substance to their program. The program originated in August, 1945, but assumed national proportion with the government of Vargas in 1951. Lack of American cooperation forced Vargas to establish a secret program with Germany. American troops intervened taking over the German equipment already completed. The final collapse came about with Vargas' suicide in August, 1954.

    The reproducibility of variables commonly included in studies of peripheral nerve conduction in healthy individuals has not previously been analyzed using a random effects regression model. We examined the temporal changes and variability of standard nerve conduction measures in the leg. Peroneal nerve distal motor latency, motor conduction velocity, and compound motor action potential amplitude; sural nerve sensory action potential amplitude and sensory conduction velocity; and tibial nerve minimal F-wave latency were examined in 51 healthy subjects, aged 40 to 67 years. They were reexamined after 2 and 26 weeks. There was no change in the variables except for a minor decrease in sural nerve sensory action potential amplitude and a minor increase in tibial nerve minimal F-wave latency. Reproducibility was best for peroneal nerve distal motor latency and motor conduction velocity, sural nerve sensory conduction velocity, and tibial nerve minimal F-wave latency. Between-subject variability was greater than within-subject variability. Sample sizes ranging from 21 to 128 would be required to show changes twice the magnitude of the spontaneous changes observed in this study. Nerve conduction studies have a high reproducibility, and variables are mainly unaltered during 6 months. This study provides a solid basis for the planning of future clinical trials assessing changes in nerve conduction.

    High tibial osteotomy is a method of treating knee osteoarthritis due to genu varum in advanced stages. High tibial osteotomy-associated problems continue to be reported. The purpose of this study was to investigate the clinical results of a new, innovative method of high tibial osteotomy with 3- to 13-year follow-up. Between 1996 and 2006, our new surgical method was performed on 293 patients with medial compartment osteoarthritis and genu varum. All patients were examined preoperatively, 6 months postoperatively, and at final follow-up. The Hospital for Special Surgery Knee Scoring System (HSS) was used at final follow-up, and limb alignment and patient satisfaction were reassessed. Immediate postoperative complications included varus recurrence, knee instability, and peroneal nerve palsy, and no signs of tibial nonunion or infection were observed. At final follow-up, 3 cases of genu recurvatum, 2 cases of peroneal nerve palsy, and 25 cases of loss of correction were observed. Average postoperative HSS score was 85 (range, 47-97), and 97.8% of the patients were satisfied. This new method is a good alternative for the correction of genu varum because it requires a small incision, is soft tissue friendly, is a corticotomy instead of an osteotomy, requires no internal or external fixation devices, has a shorter duration and an acceptable complication and recurrence rate, and results in satisfactory HSS scores and higher patient satisfaction rates.

  7. Endoscopic treatment of calcaneo-fibular impingement.

    The calcaneo-fibular impingement syndrome is frequent after calcaneal fracture and is linked to the decreased space between the tip of the fibula and the lateral wall of the calcaneus. The reasons for the painful symptoms are mixed with both bony and soft tissue involvement. The abnormal bony contact between the lateral calcaneal cortex and the tip of the fibula depends mainly on the size and localization of the lateral exostosis of the calcaneal wall. The soft tissue impingement is due to the fibrosis and scar tissues in the lateral gutter and to the compression of the peroneal tendons in the retromalleolar groove and under the tip of the malleolus. A 2-portal endoscopic technique is described for the treatment of calcaneo-fibular impingement with bone resection, soft tissue debridement and peroneal tendons release. One of the advantages of this endoscopic technique is the possibility of an assessment and treatment of associated lesions in the same procedure. A subtalar joint fusion can be done before if needed under arthroscopic control. As this endoscopic technique is very efficient to relieve symptoms of calcaneo-fibular impingement and is focused on the most relevant symptoms, it can thus be indicated for most of cases of calcaneal malunions, whatever the type of malunion and depending of the painful symptoms.

    A group of forty-nine hemiparetic patients with limited emotional, communication and sensibility involvement and with recent lesion of cerebrovascular aetiology was randomly divided into two groups of twenty-four and twenty-five subjects. Both groups received traditional physiotherapy treatment for one hour/day, one group received twenty min/day of peroneal nerve stimulation. The maximum voluntary dorsal flexion moments of the ankle joint of the affected and non affected extremities were measured with an isometric brace twice a week for one month and for both groups. The recovery of moment in the stimulated group turned out to be about three times greater than in the control group and considerably less dependent upon age, time from lesion, initial value, side of lesion. Three patients using a peroneal brace at home as an assisting device were again evaluated two months later and a further improvement was observed. This work gives statistical support to previous observations based on very few cases and provides a statistically reliable answer concerning the entity of FES induced recovery of muscle force in hemiparetic subjects.

  9. MRI Findings of Causalgia of the Lower Extremity Following Transsphenoidal Resection of Pituitary Tumor

    Full Text Available Background. Causalgia is continuing pain, allodynia, or hyperalgesia after nerve injury with edema, changes in skin blood flow, or abnormal sudomotor activity. Here we report a case of lower extremity causalgia following elective transsphenoidal resection of a pituitary tumor in a young man. Clinical Presentation. A 33-year-old man with acromegaly underwent elective sublabial transsphenoidal resection of his pituitary tumor. During the three-hour surgery, the lower limbs were kept in a supine, neutral position with a pillow under the knees. The right thigh was slightly internally rotated with a tape to expose fascia lata, which was harvested to repair the sella. Postoperatively, he developed causalgia in a distal sciatic and common peroneal nerve distribution. Pain was refractory to several interventions. Finally, phenoxybenzamine improved his pain significantly. Conclusions. Malpositioning in the operating room resulted in causalgia in this young man. Phenoxybenzamine improved, and ultimately resolved, his symptoms. Improvement in his pain symptoms correlated with resolution of imaging changes in the distal sciatic and peroneal nerves on the side of injury.

    Prolonged muscle denervation results in poor functional recovery after nerve repair. The possible protective effect of temporary sensory innervation of denervated muscle, prior to motor nerve repair, has been examined in the rat. Soleus and gastrocnemius muscles were denervated by cutting the tibial nerve, and the peroneal nerve was then sutured to the transected distal tibial nerve stump either immediately or after two, four or six months. In half of the animals with delayed repair, the saphenous (sensory) nerve was temporarily attached to the distal nerve stump. Muscles were evaluated three months after the peroneal-to-tibial union, and were compared with each other, with unoperated control muscles and with untreated denervated muscles. After four to six months of sensory "protection", gastrocnemius muscles weighed significantly more than unprotected muscles, and both gastrocnemius and soleus muscles exhibited better preservation of their structure, with less fiber atrophy and connective tissue hyperplasia. The maximum compound action potentials were significantly larger in gastrocnemius and soleus muscles following sensory protection, irrespective of the delay in motor nerve union. Isometric force, although less than in control animals and in those with immediate nerve repair, remained reasonably constant after sensory protection, while in unprotected muscles there was a progressive and significant decline as the period of denervation lengthened. We interpret these results as showing that, although incapable of forming excitable neuromuscular junctions, sensory nerves can nevertheless exert powerful trophic effects on denervated muscle fibers. We propose that these findings indicate a useful strategy for improving the outcome of peripheral nerve surgery.

    Full Text Available The overthrow of Peronism and the subsequent establishmentof the Revolución Libertadora regime (Liberating Revolutionfavored the emergence of a process of transformation of publicspeech, mainly issued by the press. The deperonization processinvolved a series of innovations in the public sphere in a way thatall references to the deposed regime were replaced to favor anopenly antiperonist discourse.In this framework, a process was started to impugn those elementslinked to Peronism; the press took an active role questioningthe State and demanding the suppression of any traces of theprevious government, such as the names of public places.The campaign promoted by Jujuy newspapers, specifically theCrónica, demanded renaming and renormalizing spaces namedafter indigenous appeals, such as the Plaza Tupac Amaru. Thenewspaper founded this change on the explicit savagery conditionassigned by the newspaper to the person referred to in the nameof the place.This pejorative treatment can be traced back during the Peronistgovernment and became part of the constitutive principles ofAntiperonism. This practice was expressed during this periodby reissuing the historic slogan “civilization and barbarism”(“civilización y barbarie”.This paper is aimed at determining the characteristics of theracist dimension of Antiperonism depending on the constitutionof its specific representations about particular historical events.

    Injection into the posterior subtalar joint has not been validated for accuracy using radiographic end points. We asked whether needle placement into a normal posterior subtalar joint could be performed accurately and selectively by experienced surgeons without fluoroscopic guidance. Three fellowship-trained orthopaedic foot and ankle surgeons each injected the posterior subtalar joint of 20 cadaveric specimens using an anterolateral approach. Fluoroscopic images were obtained by an independent investigator and blinded. A separate fellowship-trained foot and ankle surgeon interpreted the images. Of 60 injections, 58 were accurate and two were extraarticular based on interpretation by an independent foot and ankle surgeon. Extravasation into the ankle occurred in 14 samples and into the peroneal sheath in two samples. Experienced surgeons can place intraarticular injections into a radiographically normal posterior subtalar joint without fluoroscopy with a high degree of accuracy. However, extravasation into the ankle or peroneal tendon sheath occurred in an unpredictable fashion, suggesting selectivity of injection placement is relatively limited without the use of fluoroscopy. Fluoroscopy may not be necessary for injections used solely for therapeutic purposes. However, if the injection is intended for diagnostic purposes or to assist in surgical decision-making or if the joint is abnormal, we recommend fluoroscopy to ensure the subtalar joint is the only anatomic structure impacted by the injection.

    This study evaluated the reproducibility of nerve function assessment in a group of 132 diabetic patients with moderate peripheral polyneuropathy. Patients were investigated at the beginning and the end of the run-in period (a 1-month placebo period) of a multicentre trial of an aldose-reductase inhibitor (Ponalrestat). Reproducibility was evaluated by performing four types of tests: quantitative visual scales of symptoms, quantitative sensory assessment (vibration perception thresholds in medial malleolus and great toe, foot thermal perception threshold to hot and cold), electrophysiological investigations on the dominant side (conduction velocities and potential amplitudes of sensory and median motor nerve, sural and peroneal nerves, amplitudes of F waves of median motor and peroneal nerves) and cardiac autonomic tests (Valsalva, deep-breathing, lying-to-standing). Reproducibility was poor for symptoms, thermal sensitivity, and potential amplitudes. It was satisfactory (total coefficient of variation waves and the three autonomic tests. For most of the parameters total variance was mainly related to inter-subject variability. However, inter-subject variability for the three cardiac autonomic tests was very low and at least one cardiac autonomic test was altered in all the patients. Inter-centre variability was low for all the parameters, except for action potential amplitudes and for F wave velocity of the median motor nerve. This study suggests those parameters that are appropriate for the assessment of diabetic neuropathy and for therapeutic trials.(ABSTRACT TRUNCATED AT 250 WORDS)

    Foot drop is generally a consequence of common peroneal or sciatic nerve injury or L5 radiculopathy but rarely, it can be a manifestation of conversion disorder. A 24-year-old male presented with a foot drop on left side that developed overnight. He had difficulty walking with a trunk tilt towards right side and numbness in left leg up to mid-thigh. The initial diagnosis by the general practitioner was common peroneal nerve injury, which was not supported by the subsequent detailed examination in the physiatry department. Routine laboratory investigations, computed tomographic scan of brain and electrophysiological evaluation were normal. In a multidisciplinary team evaluation involving a psychiatrist, he was diagnosed to be suffering from conversion disorder and was advised gait retraining, cognitive and behavioral therapy and tablet venlafaxine. By sixth day of treatment, the patient was able to walk independently with a normal gait pattern and reported complete recovery of his symptoms. In the absence of an identifiable organic cause of foot drop in a patient, conversion disorder may be considered necessitating early intervention by a psychiatrist.

    Early diagnosis of diabetic peripheral neuropathy is important for the successful treatment of diabetes mellitus. In the present study, we recruited 500 diabetic patients from the Fourth Afifl-iated Hospital of Kunming Medical University in China from June 2008 to September 2013: 221 cases showed symptoms of peripheral neuropathy (symptomatic group) and 279 cases had no symptoms of peripheral impairment (asymptomatic group). One hundred healthy control sub-jects were also recruited. Nerve conduction studies revealed that distal motor latency was longer, sensory nerve conduction velocity was slower, and sensory nerve action potential and amplitude of compound muscle action potential were signiifcantly lower in the median, ulnar, posterior tibial and common peroneal nerve in the diabetic groups compared with control subjects. More-over, the alterations were more obvious in patients with symptoms of peripheral neuropathy. Of the 500 diabetic patients, neural conduction abnormalities were detected in 358 cases (71.6%), among which impairment of the common peroneal nerve was most prominent. Sensory nerve abnormality was more obvious than motor nerve abnormality in the diabetic groups. The ampli-tude of sensory nerve action potential was the most sensitive measure of peripheral neuropathy. Our results reveal that varying degrees of nerve conduction changes are present in the early, as-ymptomatic stage of diabetic peripheral neuropathy.

    The effects of large dose methylcobalamin injection on diabetic peripheral neuropathy in patients were observed to observe the subjective symptom of diabetic perpheral neuropathy (DPN) patients and detect the motor nerve conduction velocity (MCV) and sense nerve conduction velocity (SCV). Fifteen patients were received large dose methylcobalamin injection for two weeks as treatment group, another eleven patients were received muscular injection VitB1 100mg/ d, VitB12 500ug/ d for two weeks as control group. After 2 weeks treatment the subjective symptoms and signs were significantly improved with a total effective rate of 82.9% in the treatment group however the effective rate only has 52.0% in the control group. The result has obvious difference in statistics nerve MCV in median common peroneal nerve, SCV in median and superficial peroneal nerve were improved significantly in the treatment group and no such changes were observed in the control group. So, large dose methylcobalamin is an effective and safe agent for treatment of diabetic peripheral neuropathy.

    Full Text Available CONTEXT AND OBJECTIVE: One of the techniques used for treating facial paralysis is double muscle innervation using end-to-end neurorrhaphy with sectioning of healthy nerves. The aim of this study was to evaluate whether double muscle innervation by means of end-to-side neurorrhaphy could occur, with maintenance of muscle innervation. DESIGN AND SETTING: Experimental study developed at the Experimental Research Center, Faculdade de Medicina de Botucatu, Unesp. METHODS: One hundred rats were allocated to five groups as follows: G1, control group; G2, the peroneal nerve was sectioned; G3, the tibial nerve was transected and the proximal stump was end-to-side sutured to the intact peroneal nerve; G4, 120 days after the G3 surgery, the peroneal nerve was sectioned proximally to the neurorrhaphy; G5, 120 days after the G3 surgery, the peroneal and tibial nerves were sectioned proximally to the neurorrhaphy. RESULTS: One hundred and fifty days after the surgery, G3 did not show any change in tibial muscle weight or muscle fiber diameter, but the axonal fiber diameter in the peroneal nerve distal to the neurorrhaphy had decreased. Although G4 showed atrophy of the cranial tibial muscle 30 days after sectioning the peroneal nerve, the electrophysiological test results and axonal diameter measurement confirmed that muscle reinnervation had occurred. CONCLUSION: These findings suggest that double muscle innervation did not occur through end-to-side neurorrhaphy; the tibial nerve was not able to maintain muscle innervation after the peroneal nerve had been sectioned, although muscle reinnervation was found to have occurred, 30 days after the peroneal nerve had been sectioned.CONTEXTO E OBJETIVO: Uma das técnicas utilizadas para tratamento da paralisia facial é a dupla inervação muscular com neurorrafia término-terminal, seccionando-se nervos sadios.

    Objective To study the association between lower limb venous valve insufficiency and lower limb peripheral neuropathy (PN) in elderly T2DM patients. Methods The function of lower extremity deep venous valves and PN of 43 elderly T2DM patients were checked with color Doppler ultrasound and electromyography. An analysis on the rank correlation evaluation of venous valve function with peripheral neuropathy was performed according to the different degrees of venous valve insufficiency. Results Latency of the right peroneal motor nerve was positively correlated with the degree of lower limb venous valve insufficiency (P<0. 05). Latency of the left peroneal motor nerve and bilateral tibial motor nerves was positively correlated with the degree of lower limb venous valve insufficiency (P<0. 01). Sensory nerve conduction velocity of the left peroneal nerve was negatively correlated with the degree of lower limb venous valve insufficiency (P<0. 05). Motor nerve conduction velocity of bilateral peroneal nerves and sensory nerve conduction velocity of bilateral tibial nerves and the right peroneal nerve were negatively correlated with the degree of lower limb venous valve insufficiency (P<0. 01). Conclusion The degree of lower limb venous valve insufficiency is probably correlated with the degree of lower limb peripheral neuropathy.%目的 探讨老年T2DM下肢深静脉瓣功能不全与下肢周围神经病变的关系.方法 对43例老年T2DM患者,行下肢静脉二维彩色多普勒超声检查及肌电图检查,按静脉瓣功能不全程度分组进行秩和相关分析.结果 右腓运动神经潜伏期与下肢静脉瓣功能不全程度呈正相关(P<0.05),左腓、双胫运动神经潜伏期与下肢静脉瓣功能不全程度呈显著正相关(P<0.01);左腓感觉神经传导速度与下肢静脉瓣功能不全程度呈负相关(P<0.05),双腓运动神经传导速度、双胫及右腓感觉神经传导速度与下肢静脉瓣功能不

  20. Impacts and Ophiolites: A Way to Recognize Large Terrestrial Impact Basins?

    Science.gov (United States)

    Olds, E. P.

    2015-12-01

    That Chicxulub Crater is located on ~35 km thick continental crust is apparently inconsistent with oceanic crustal/upper mantle geochemical signatures detected globally in the KT boundary impact layer [1-5 and unpublished Cr isotope data from the Yin lab at UC Davis] since introduction of the Alvarez hypothesis [6]. Apparent excavation and ejection of mafic/ultramafic target rock by the KT boundary impact might imply an additional KT impact site involving oceanic lithosphere. We speculate: 1) The Greater Antilles island chain ophiolite belt marks the rim of a ~700 km diameter impact basin, deformed and dismembered from an originally circular form by at least 50 million years of left lateral shear on the North American-Caribbean transform plate boundary; 2) Other ophiolite segments may similarly mark rims of large impact basins deformed to greater or lesser extent by, and serving as strain markers for, relative plate motions over geologic time; 3) The Greater Antilles/Chicxulub and Sulu Sea Basin/Spratly Island cases may constitute doublet craters of similar size ratio and separation distance; 4) Plate boundaries may be formed or modified by such impacts. Problems include: 1) The KT fireball layer should be tens of cm thick rather than a few mm thick [8-9]; 2) Impact basins of this size/scale are not expected in the Phanerozoic/Proterozoic [10]; References: [1] DePaolo D.

  1. Hydrological AnthropoScenes

    The Anthropocene concept encapsulates the planetary-scale changes resulting from accelerating socio-ecological transformations, beyond the stratigraphic definition actually in debate. The emergence of multi-scale and proteiform complexity requires inter-discipline and system approaches. Yet, to reduce the cognitive challenge of tackling this complexity, the global Anthropocene syndrome must now be studied from various topical points of view, and grounded at regional and local levels. A system approach should allow to identify AnthropoScenes, i.e. settings where a socio-ecological transformation subsystem is clearly coherent within boundaries and displays explicit relationships with neighbouring/remote scenes and within a nesting architecture. Hydrology is a key topical point of view to be explored, as it is important in many aspects of the Anthropocene, either with water itself being a resource, hazard or transport force; or through the network, connectivity, interface, teleconnection, emergence and scaling issues it determines. We will schematically exemplify these aspects with three contrasted hydrological AnthropoScenes in Tunisia, France and Iceland; and reframe therein concepts of the hydrological change debate.

The dynamical approach improves reliability, skills and sharpness of forecasts and globally reduces confidence intervals width. When compared in details, the dynamical approach allows a noticeable reduction of confidence intervals during recessions where uncertainty is relatively lower and a slight increase of confidence intervals during rising limbs or snowmelt where uncertainty is greater. The dynamic approach, validated by forecaster's experience that considered the empirical approach not discriminative enough, improved forecaster's confidence and communication of uncertainties.

    Background notes on Argentina provide a profile of the geography, selected demographic features, government and economic conditions. Descriptive text includes a discussion of the people, their history and political conditions, the government and officials, the state of the economy, their defense, foreign relations, and relations with the US. The 1992 estimated population was about 33 million of whom 97% are European (mostly Spanish and Italian). Religions represented are Roman Catholic (92%), Protestant (2%), Jewish (2%), and other (4%). Adult literacy is 95%. 36% are engaged in industry and commerce, 20% in services, 19% in agriculture, 6% in transport and communications, and 19% other. Per capita gross domestic product was $4,500. There are only 50,000 native Indians remaining in peripheral provinces. The population enjoys a high standard of living and a low growth rate. The country was shaped by dominant forces: modern agricultural techniques and the integration of the country into the world economy. Foreign investment aided the economic revolution. Conservative and radical rule has swung the country back and forth politically since 1916. Colonel Juan Domingo Peron led a successful military coup in 1943 and was elected in 1946. Policies were instituted to give a greater voice to the working class, and with the influences of his wife, women's groups. In 1955, he was ousted by the military, which failed to revive the economy and quiet increasing terrorism. After a number of difficult elections, Peron was reinstated as president in 1973. Extremists on the left and right threatened public order; the military as a consequence imprisoned persons indefinitely. Peron's wife succeeded him after his death, but was removed from office in the military coup of 1976. Basic human rights were violated during this period. By 1983, a fair election was held and support increased for a democratic system. In 1989, Carlos Saul Menem, a Peronist candidate, won and established

    AIM: Cardiovascular autonomic and peripheral sensory neuropathy is a known complication of chronic alcoholic and non-alcoholic liver diseases. We aimed to assess the prevalence and risk factors for peripheral sensory nerve and autonomic dysfunction using sensitive methods in patients with primary biliary cirrhosis (PBC).METHODS: Twenty-four AMA M2 positive female patients with clinical, biochemical and histological evidence of PBC and 20 age matched healthy female subjects were studied.Five standard cardiovascular reflex tests and 24-h heart rate variability (HRV) analysis were performed to define autonomic function. Peripheral sensory nerve function on median and peroneal nerves was characterized by current perception threshold (CPT), measured by a neuroselective diagnostic stimulator (Neurotron, Baltimore, MD).RESULTS: Fourteen of 24 patients (58%) had at least one abnormal cardiovascular reflex test and thirteen (54%)had peripheral sensory neuropathy. Lower heart rate response to deep breathing (P = 0.001), standing (P = 0.03)and Valsalva manoeuvre (P = 0.01), and more profound decrease of blood pressure after standing (P = 0.03) was found in PBC patients than in controls. As a novel finding we proved that both time domain and frequency domain parameters of 24-h HRV were significantly reduced in PBC patients compared to controls. Each patient had at least one abnormal parameter of HRV. Lower CPT values indicated hyperaesthesia as a characteristic feature at peroneal nerve testing at three frequencies (2000 Hz: P = 0.005;250 Hz: P = 0.002; 5 Hz: P = 0.004) in PBC compared to controls. Correlation of autonomic dysfunction with the severity and duration of the disease was observed. Lower total power of HRV correlated with lower CPT values at median nerve testing at 250 Hz (P = 0.0001) and at 5 Hz (P = 0.002), as well as with those at peroneal nerve testing at 2000 Hz (P = 0.01).CONCLUSION: Autonomic and sensory nerve dysfunctions are frequent in PBC.

    Full Text Available Resumen Este artículo se propone analizar la relación que el peronismo local estableció con las asociaciones de base. Éstas constituyen la unidad de análisis elegida, y serán entendidas como organizaciones de la sociedad civil. A partir de este estudio de caso se demostrará que las entidades fomentistas existentes durante los años peronistas mantuvieron sus actividades emblemáticas, el peronismo no ocluyó esa dinámica civil pero buscó controlarla y regularla jurídicamente, además consiguió peronizar algunas de ellas pero no ocurrió así con las organizaciones que se constituyeron en los años terminales del peronismo. Más aún, éstas crecieron geométricamente durante el posperonismo. Sobre la base de las fuentes periodísticas, de actas asamblearias y de las entrevistas a vecinalistas que protagonizaron la génesis del movimiento en 1954, se da cuenta de la continuidad de la práctica fomentista así como las diferencias que marcaron al nuevo vecinalismo en Río Cuarto, una ciudad del sur cordobés. Abstract This article intends to analyze the relationship of based partnerships established local peronism. These constitute the unit of analysis that is chosen, and will be understood as civil society organizations. From this case study will demonstrate that entities existing fomentistas during the Peronist years maintained its flagship activities, peronism not occluded that dynamic civil but sought to control and regulate it legally, also got peronizar some of them but did not take place as well with organizations that peronism terminals were formed over the years. Moreover, these grew geometrically over the posperonismo. On the basis of journalistic sources, assembly records and interviews with vecinalistas that they were the genesis of the movement in 1954, he realizes the defense of autonomy and efforts at co-opting municipal in Rio Cuarto, a city in southern Cordoba.

    Background The accurate assessment of peripheral venous flow is important for the early diagnosis and treatment of disorders such as deep-vein thrombosis (DVT) which is a major cause of post-thrombotic syndrome or even death due to pulmonary embolism. The aim of this work is to quantitatively determine blood flow in deep veins during rest and muscular exercise using a novel real-time magnetic resonance imaging (MRI) method for velocity-encoded phase-contrast (PC) MRI at high spatiotemporal resolution. Methods Real-time PC MRI of eight healthy volunteers and one patient was performed at 3 Tesla (Prisma fit, Siemens, Erlangen, Germany) using a flexible 16-channel receive coil (Variety, NORAS, Hoechberg, Germany). Acquisitions were based on a highly undersampled radial FLASH sequence with image reconstruction by regularized nonlinear inversion at 0.5×0.5×6 mm3 spatial resolution and 100 ms temporal resolution. Flow was assessed in two cross-sections of the lower leg at the level of the calf muscle and knee using a protocol of 10 s rest, 20 s flexion and extension of the foot, and 10 s rest. Quantitative analyses included through-plane flow in the right posterior tibial, right peroneal and popliteal vein (PC maps) as well as signal intensity changes due to flow and muscle movements (corresponding magnitude images). Results Real-time PC MRI successfully monitored the dynamics of venous flow at high spatiotemporal resolution and clearly demonstrated increased flow in deep veins in response to flexion and extension of the foot. In normal subjects, the maximum velocity (averaged across vessel lumen) during exercise was 9.4±5.7 cm·s−1 for the right peroneal vein, 8.5±4.6 cm·s−1 for the right posterior tibial vein and 17.8±5.8 cm·s−1 for the popliteal vein. The integrated flow volume per exercise (20 s) was 1.9, 1.6 and 50 mL (mean across subjects) for right peroneal, right posterior tibial and popliteal vein, respectively. A patient with DVT presented with

    Infracranial nonmetric variations have been considered for determining population distance between different regions and continents, in recent times. We studied different infracranial nonmetric traits from the Dakshina Kannada (South India) region to compare with the data available from the Gujarati (North India) region. The mean measure of divergence between the two different geographic regions showed significant variation. In our study, the incidence like i) Allen's fossa of the femur, ii) plaque formation in the upper end of the femur, iii) exostosis in trochanteric fosse of femur, iv) third trochanter of femur, v) os trigonum of talus, vi) medial talar facet, vii) peroneal tubercle of calcaneus, viii) bipartite transverse foramen in the cervical vertebra, too showed significant side difference.

    OBJECTIVES: It is still unclear to what an extent altered reflex activity contributes to gait deficit following stroke. Spinal group I and group II excitations from ankle dorsiflexors to knee extensors were investigated during post-stroke walking. METHODS: Electrical stimulation was applied...... to the common peroneal nerve (CPN) in the early stance, and the short-latency biphasic excitation in Quadriceps motoneurones was evaluated from the Vastus Lateralis (VL) rectified and averaged (N=50) EMG activity in 14 stroke patients walking at 0.6-1.6 km/h, and 14 control subjects walking at 3.2-4.8 and at 1......: The spinal, presumed group II, excitation from ankle dorsiflexors to knee extensors is particularly enhanced during post-stroke walking probably due to plastic adaptations in the descending control. SIGNIFICANCE: This adaptation may help to stabilize the knee in early stance when the patients have recover...

  11. Effects of spinal and peripheral nerve lesions on the intersegmental synchronization of the spontaneous activity of dorsal horn neurons in the cat lumbosacral spinal cord.

    In the anesthetized and paralyzed cat, spontaneous negative cord dorsum potentials (nCDPs) appeared synchronously in the L3 to S1 segments, both ipsi- and contralaterally. The acute section of both the intact sural and the superficial peroneal nerve increased the variability of the spontaneous nCDPs without affecting their intersegmental coupling. On the other hand, the synchronization between the spontaneous nCDPs recorded in segments L5-L6 was strongly reduced following an interposed lesion of the left (ipsilateral) dorsolateral spinal quadrant and it was almost completely abolished by an additional lesion of the contralateral dorsolateral quadrant at the same level. Our observations support the existence of a system of spontaneously active dorsal horn neurons that is bilaterally distributed along the lumbosacral segments and affects, in a synchronized and organized manner, impulse transmission along many reflex pathways, including those mediating presynaptic inhibition.

    The purpose of the present study was to determine the effect of leg exercise training on sympathetic nerve responses at rest and during dynamic exercise. Six men were trained by using high-intensity interval and prolonged continuous one-legged cycling 4 day/wk, 40 min/day, for 6 wk. Heart rate, mean arterial pressure (MAP), and muscle sympathetic nerve activity (MSNA; peroneal nerve) were measured during 3 min of upright dynamic one-legged knee extensions at 40 W before and after training. After training, peak oxygen uptake in the trained leg increased 19 +/- 2% (P leg exercise and indicates that attenuation of MSNA to exercise reported with forearm training also occurs with leg training.

  15. Fine Needle Aspiration Cytology in Diagnosis of Pure Neuritic Leprosy

    2011-01-01

    Full Text Available Leprosy is a chronic infection affecting mainly the skin and peripheral nerve. Pure neuritic form of this disease manifests by involvement of the nerve in the absence of skin lesions. Therefore, it can sometimes create a diagnostic problem. It often requires a nerve biopsy for diagnosis, which is an invasive procedure and may lead to neural deficit. Fine needle aspiration cytology (FNAC of an affected nerve can be a valuable and less invasive procedure for the diagnosis of such cases. We report five suspected cases of pure neuritic Hansen's disease involving the common and superficial peroneal, ulnar, and median nerve, who underwent FNAC. Smears revealed nerve fibers infiltrated by chronic inflammatory cells in all cases, presence of epithelioid cells granulomas, and Langhans giant cells in three cases, and acid fast bacilli in two cases. In conclusion, FNAC is a safe, less invasive, and time saving procedure for the diagnosis of pure neuritic leprosy.

    Acute compartment syndrome of the lower leg is usually associated with major trauma such as fracture, and most commonly occurs in the anterior or deep posterior compartments. Isolated lateral compartment syndrome is less typical and usually associated with minor trauma or exertion. There are a few reports of the acute compartment syndrome which develops without an obvious cause. However, there are few reports of idiopathic acute isolated lateral compartment syndrome, and there are no reports of the radiologic findings. This study presents a radiologic finding of idiopathic acute isolated lateral compartment of lower leg, which shows localized enlargement of the peroneal muscles with peripheral convex bowing and change of their signal intensity with fluid signal along the adjacent fascial planes on magnetic resonance imaging.

    2016-07-01

    Lower leg fasciotomy may be performed with a single lateral incision with or without fibulectomy, or by a double incision technique, with most surgeons preferring the later. The aim of this article is to describe a variation of an existing single-incision technique that will allow for the release of all four compartments with 1 incision. Our approach uses a paratibial route to release the deep posterior compartment (DPC) rather than a transfibular or parafibular route that has already been discussed in the literature. We approach the DPC from the anterior compartment, whereas the parafibular approach uses the posterior aspect of the fibula to reach the DPC. This affords a faster fasciotomy with a smaller flap, avoids potential damage to neurovascular bundle and among other advantages, makes its especially pragmatic for bedside fasciotomy, without the risk of injury to the peroneal nerves, which is common with dissection at the posterior aspect of the fibula.

    Full Text Available Background: Post injection sciatic nerve injury is a common cause of sciatic nerve mononeuropathy in the developing world largely due to inadequate health care facilites in the rural regions. Objective: The study was conducted to analyse the pattern of this nerve lesion in clinical and electrophysiological parameters and also to study the outcome in a conservatively treated cohort. Materials and Methods: One hundred and six patients who underwent evaluation at our laboratory from 2000 to 2006 for post injection sciatic neuropathy formed the study population. Twenty two of these were followed up (mean 6.6 months for the outcome. Results: In the cases with full data, common peroneal division of the sciatic nerve was affected alone or predominantly. On follow up, 72% cases showed little or partial recovery. Thirty two percent patients had residual trophic changes and causalgia at their last visit. Conclusion: The majority of cases of postinjection sciatic nerve injury have poor prognosis on conservative treatment.

    Training in sports medicine and rehabilitation medicine requires the establishment of conditioned reflexes. Reinforcement of a conditioned reflex is more effective when it is part of a set of two or three reflexes. The late spinal reflexes appearing after conditioning were resolved into a stretch reflex and a spino-bulbo-spinal (SBS) reflex. H and M waves on the tibialis anterior muscle induced by tibial nerve stimulation were determined from the escape potential of the triceps sural muscle contraction. The tibial nerve and peroneal nerve were stimulated bilaterally, and H and M waves from the triceps sural muscle and tibialis anterior muscle were recorded bilaterally. The complete separation method of the late response and the time course of the stretch reflex and SBS reflex that composed the late response are described in this paper.

    Full Text Available Emery-Dreifuss muscular dystrophy (EDMD, a rare inherited disease, is characterized clinically by humero-peroneal muscle atrophy and weakness, multijoint contractures, spine rigidity and cardiac insufficiency with conduction defects. There are at least six types of EDMD known so far, of which five have been associated with mutations in genes encoding nuclear proteins. The majority of the EDMD cases described so far are of the emerinopathy (EDMD1 kind, with a recessive X-linked mode of inheritance, or else laminopathy (EDMD2, with an autosomal dominant mode of inheritance. In the work described here, the authors have sought to describe the history by which EDMD came to be distinguished as a separate entity, as well as the clinical and genetic characteristics of the disease, the pathophysiology of lamin-related muscular diseases and, finally, therapeutic issues, prevention and ethical aspects.

    The classification of certain vascular bone tumors that show an epithelioid cytologic appearance remains confusing, with overlap in features of epithelioid hemangioma, hemangioendothelioma and epithelioid hemangioendothelioma. Radiographs of a 27-year-old woman who presented with ankle pain showed an expanded lytic-sclerotic lesion in the distal left fibula. Magnetic resonance imaging showed an intramedullary lesion with a small lateral intracortical component. The lesion was hypo- to isointense to muscle on T1-weighted images and heterogeneously hyperintense on T2-weighted images. Initial incisional biopsy was inconclusive. Open biopsy showed hemangioendothelioma with epithelioid morphology, and the lesion was completely resected with reconstruction using a peroneal fibular rotation graft. Examination of the resected specimen showed focal hemangioendothelioma with an epithelioid phenotype arising in a hemangioma. This case illustrates the difficulty and pitfalls of making the correct diagnosis on the basis of a small biopsy specimen. (orig.)

    2012-11-01

    Painful polyneuropathy may result from selective impairment of small diameter nerve fibers, while tactile and motor functions are preserved. In these patients clinical and electrophysiological assessment is usually unrevealing. We report three patients with a pure painful polyneuropathy. One of them had neurogenic pruritus additionally. Quantitative sensory analysis disclosed a slight warm hypoesthesia (3/3) and paradoxical hot sensation (2/3) in the feet. Intraneural recordings from the peroneal nerve demonstrated abnormal spontaneous activity in 8 of 17 nociceptive afferents. One of them displayed double firing reflecting impulse multiplication. These results support the notion that patients with pain or pruritus with a distal distribution similar to a polyneuropathy, could have small diameter afferent fiber damage, despite normal function of large diameter fibers.

    Full Text Available A 53-year-old woman with non-productive cough of unexplained aetiology for two years, developed a sub-acute symmetrical polyneuropathy involving all four limbs, accompanied by fever, cutaneous rash and myalgia in lower limbs. Laboratory studies revealed a leukocytosis with 70% eosinophils and excluded any cause for the hypereosinophilia. An echocardiogram showed increase in thickness of the atrial septum. Motor and sensory conduction velocity were reduced in ulnar and median nerve, and unrecordable in peroneal and tibial nerves. A sural nerve biopsy showed an axonal degeneration involving myelinated and unmyelinated fibers as well as a vasculitis with fibrinoid necrosis and perivascular infiltration of eosinophils. There was considerable clinical and laboratorial improvement with the use of steroids. The differential diagnosis between idiopathic hypereosinophilic syndrome and other disorders known to course with vasculitis and hypereosinophilia is discussed.

    Full Text Available Objective: Hereditary neuropathy with liability to pressure palsy (HNPP needs to be differentiated from entrapment neuropathies due to differences in the treatment management. Materials and Methods: Among 5075 patients with entrapment neuropathy, we retrospectively evaluated the neurophysiologic results of 20 patients with three or more entrapments. Results: Ten patients were diagnosed as having HNPP according to their genetic or nerve biopsy results; eight (80% had bilateral Carpal tunnel syndrome, nine (90% had bilateral ulnar entrapment neuropathy, eight (80% had bilateral median and ulnar entrapment together; and three (30% had one-sided peroneal neuropathy. Conclusion: Our data suggest that analyzing the neurophysiologic studies and keeping HNPP in mind are essential to characterize underdiagnosed patients with HNPP referred for entrapment neuropathy.

    Isolated posteromedial ankle dislocation is a rare condition thanks to the highly congruent anatomical configuration of the ankle mortise, in which the medial and lateral malleoli greatly reduce the rotational movement of the talus, and the strength of the ligaments higher than the malleoli affords protection against fractures. However, other factors, like medial malleolus hypoplasia, laxity of the ligaments, peroneal muscle weakness and previous ankle sprains, could predispose to pure dislocation. In the absence of such factors, only a complex high-energy trauma, with a rotational component, can lead to this event. Irreducibility of an ankle dislocation, which is rarely encountered, can be due to soft tissue interposition. Dislocation of the posterior tibial tendon can be the cause of an irreducible talar dislocation; interposition of this tendon, found to have slid posteriorly to the distal tibia and then passed through the tibioperoneal syndesmosis, is reported in just a few cases of ankle fracture-dislocation.

    Full Text Available Introduction: Mononeuropathies, in general, are very uncommon in childhood. Sciatic neuropathy (SN is probably underappreciated in childhood and likely to represent nearly one quarter of childhood mononeuropathies. Materials and Methods: We present a 7-year-old girl who presented with painful right lower limb and abnormal gait. Detailed investigation revealed transient eosinophilia, abnormal neurophysiology, and magnetic resonance imaging (MRI suggestive of isolated sciatic neuropathy. Results: She has responded very well to physiotherapy and has made a complete motor recovery, although she is left with an area of abnormal sensation affecting the lateral border of her right leg and the dorsum of her foot. Discussion: Differential diagnoses for pediatric SN have been discussed including compressive neuropathies in children and various hyper-eosinophilia syndromes. Compressive neuropathies in childhood are very rare and compression of the sciatic nerve is the second most common group after peroneal nerve lesion.

    BACKGROUND: Given the movement of molecules within tissue that occurs naturally by endogenous electric fields, we examined the possibility of using a low-voltage DC field to move charged substances in rodent peripheral nerve in vitro. NEW METHOD: Labeled sugar- and protein-based markers were...... applied to a rodent peroneal nerve and then a 5-10 V/cm field was used to move the molecules within the extra- and intraneural compartments. Physiological and anatomical nerve properties were also assessed using the same stimulation in vivo. RESULTS: We demonstrate in vitro that charged and labeled...... compounds are capable of moving in a DC field along a nerve, and that the same field applied in vivo changes the excitability of the nerve, but without damage. CONCLUSIONS: The results suggest that low-voltage electrophoresis could be used to move charged molecules, perhaps therapeutically, safely along...

    2011-01-01

    The purpose of this study is to investigate the transfer functions of mechanomyograms (MMGs) detected with an acceleration sensor and a laser displacement meter. The MMGs evoked by electrical stimulation to the peroneal nerve were recorded on the skin of the tibial anterior muscle. The displacement MMG (DMMG) and the acceleration MMG (AMMG) systems were identified using a singular value decomposition method. The appropriate order of the AMMG system was six and that of the DMMG system was four. The undamped natural frequencies of the systems were compared to resonance frequencies of human soft tissue. Some of the undamped natural frequencies estimated from the AMMG systems agreed with the resonance frequencies in the literature but others were lower than the resonance frequencies. The undamped natural frequencies estimated from the DMMG systems were lower than the resonance frequencies.

    2002-06-01

    We examined the peripheral nervous system (PNS) (nerve conduction velocity (NCV)) and the central nervous system (CNS) (basal ganglia-mediated psychomotor speed) in 93 males seropositive for human immunodeficiency virus type 1 (HIV-1) with no prior history of opportunistic brain disease, antiretroviral treatment or intravenous drug use. Patients with different degrees of slowing of peroneal and sural NCV showed no significant differences in psychomotor speed as assessed by tremor peak frequency, most rapid alternating movements, reaction times and contraction times. There was no significant correlation between psychomotor measures and NCV. Psychomotor slowing test findings were independent from peripheral nervous system damage indicating uncorrelated disturbances of CNS and PNS function in HIV-1 infection. Differences in HIV-1 viral quasispecies or host responses may determine the predominance of CNS or PNS injury.

    Intraneural ganglion cysts are uncommon cystic lesions of peripheral nerves that are typically encountered in adults. In the lower extremity, the peroneal nerve is most frequently affected with involvement of the tibial nerve much less common. This article describes a tibial intraneural ganglion cyst in a 10-year-old boy. Although extremely rare, intraneural ganglion cysts of the tibial nerve should be considered when a nonenhancing cystic structure with intra-articular extension is identified along the course of the nerve. This report also details the unsuccessful attempt at percutaneous treatment with US-guided cyst aspiration and steroid injection, an option recently reported as a viable alternative to open surgical resection.

    Opening wedge high tibial osteotomy (OWHTO) is a surgical procedure that aims to correct the weight-bearing axis of the knee, moving the loads laterally from the medial compartment. Conventional indications for OWHTO are medial compartment osteoarthritis and varus malalignment of the knee; recently OWHTO has been used successfully in the treatment of double and triple varus. OWHTO, in contrast to closing wedge high tibial osteotomy, does not require fibular osteotomy or peroneal nerve dissection, or lead to disruption of the proximal tibiofibular joint and bone stock loss. For these reasons, interest in this procedure has grown in recent years. The aim of this study is to review the literature on OWHTO, considering indications and prognostic factors (body mass index, grade of osteoarthritis, instability, range of movement and age), outcomes at mid-term follow-up, and limits of the procedure (slope modifications, patellar height changes and difficulties in conversion to a total knee arthroplasty).

    Full Text Available Deep vein thrombosis (DVT is caused by obstruction of blood flow of deep veins in upper and lower limb. One of the precipitating factors for DVT is surgery under general anesthesia exceeding 30 min. However, there are very few reports of DVT associated with surgery of oral and maxillofacial region. In this paper we report two cases of DVT involving left ilio-femoropopliteal deep vein in one patient treated for fractured left angle of mandible and left peroneal vein in the other patient treated for oral sub mucous fibrosis. Clinical and color Doppler examination were performed to diagnose the condition and were referred to vascular surgical unit of higher institute for further management. These cases illustrates any surgery of maxillofacial region is not free from risk of DVT, which can cause fatal pulmonary thromboembolism.

This cross-sectional study analyzes the pattern of ultrasound peripheral nerve alterations in patients with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and multifocal motor neuropathy (MMN) at different stages of functional disability. Material and Methods. 22 CIDP and 10 MMN patients and a group of 70 healthy controls were evaluated with an ultrasound scan of the median, ulnar, peroneal, tibial, and sural nerves. Results were correlated with clinical disability scales and nerve conduction studies. Results. Patients with intermediate functional impairment showed relatively larger cross-sectional areas than subjects with either a milder (p CIDP and in MMN. In addition, MMN was associated with greater side-to-side intranerve variability (p CIDP (p CIDP; p CIDP and MMN showed differential US aspects, with greater side-to-side intranerve variability in MMN and higher cross-sectional areas in CIDP.

    This study aimed to determine whether occupational exposure to pesticides was associated with decreased nerve conduction studies among farmers. On 2 separate occasions, the authors performed a cross-sectional study of a group of 31 male farmers who periodically applied pesticides. The study included questionnaire interviews and nerve conduction studies on the median, ulnar, posterior tibial, peroneal, and sural nerves. Although all mean values remained within laboratory normal limits, significant differences between the first and second tests were found in sensory conduction velocities on the median and sural nerves, and motor conduction velocities on the posterior tibial nerve. Lifetime days of pesticide application was negatively associated with nerve conduction velocities at most nerves after adjusting for potential confounders. These findings may reflect a link between occupational pesticide exposure and peripheral neurophysiologic abnormality that deserves further evaluation.

    A sciatic nerve lesion secondary to compression by a heterotopic ossification is rare. Operative release of the encased sciatic nerve in some cases may restore the function of the nerve partially or completely. However, in some cases the injury may be permanent. An electrophysiologic study is very useful to determine the location and severity of nerve damage, including axonal loss, demyelination, or both. An electrophysiologic study can emphasize the portion of the sciatic nerve that has been involved the most (lateral versus medial or peroneal versus tibial). In some cases an electrophysiologic study can suggest whether surgery should be postponed if a recovery pattern from the nerve injury is obvious. The prognostic value of follow-up studies is considerable. The authors reviewed literature available to them since 1971 and found 6 cases, including their own. This is the first attempt to put together all the information available in the literature about this condition.

    Compare the result of endoscopic versus open bursectomy in lateral malleolar bursitis. Prospective evaluation of 21 patients (22 ankles) undergoing either open or endoscopic excision of lateral malleolar bursitis. The median age was 64 (38-79) years old. The median postoperative follow-up was 15 (12-18) months. Those patients undergoing endoscopic excision showed a higher satisfaction rate (excellent 9, good 2) than open excision (excellent 4, good 3, fair 1). The wounds also healed earlier in the endoscopic group although the operation time was slightly longer. One patient in the endoscopic group had recurrence of symptoms but complications in the open group included one patient with skin necrosis, one patient with wound dehiscence, and two patients of with superficial peroneal nerve injury. Endoscopic resection of the lateral malleolar bursitis is a promising technique and shows favorable results compared to the open resection.

    1986-04-01

    We studied evoked potentials (EPs) in 27 patients with typical acute Guillain-Barré syndrome and 3 with Fisher's syndrome. Three of 21 had BAEP abnormalities: 1 with bilateral I-III, 1 with unilateral I-III, and another with unilateral III-V interwave latency prolongations. Three with Fisher's syndrome had normal BAEPs (one had a poorly formed wave V unilaterally with one click polarity only). Ten of 21 median nerve EPs and 9 of 12 peroneal or tibial nerve somatosensory EPs were abnormal. Seven patients with normal somatosensory EPs had abnormal F waves from the same nerve; none had normal late responses and abnormal somatosensory EPs. These observations differ from previous reports on the frequency and interpretation of EP abnormalities in Guillain-Barré syndrome.

    Full Text Available This article seeks to contribute to a better understanding of the political dimension to middle-class identity in Argentina, by analyzing an image that appeared after 2001: that of a “17th October of the Middle Class”. This curious image, and the shifts in its meanings from its first introduction to its most recent manifestations, is interpreted by locating it into two different contexts. On one hand, the socio-economic, political and identity changes that Argentine society experienced during and after the 1990s. On the other hand, the longer context of the trauma that the emergence of Peronism produced in 1945, which still casts effects on Argentina culture. The image of the “17th October of the Middle Class” in thus interpreted as a fantasy of closing the Peronist political horizon, by replicating the event that opened it in 1945, this time with the middle (and not the working class in the leading role

    The anatomy of the nerves of the foot and ankle is complex, and familiarity with the normal anatomy and course of these nerves as well as common anatomic variants is essential for correct identification at imaging. Ultrasonography (US) and magnetic resonance (MR) imaging allow visualization of these nerves and may facilitate diagnosis of various compression syndromes, such as "jogger's heel," Baxter neuropathy, and Morton neuroma. It may be difficult to distinguish the nerves from adjacent vasculature at MR imaging, and US can help in differentiation. The authors review the normal anatomy and common variants of the nerves of the foot and ankle, with use of dissected specimens and correlative US and MR imaging findings. In addition, the authors illustrate proper probe positioning, which is essential for visualizing the nerves at US. The authors' discussion focuses on the superficial and deep peroneal, sural, saphenous, tibial, medial and lateral plantar, medial and inferior calcaneal, common digital, and medial proper plantar digital nerves.

    Compartment syndrome after total knee arthroplasty (TKA) is a rare complication. Because of its rarity, it may be overlooked and misdiagnosed as peroneal nerve palsy or deep vein thrombosis. This misdiagnosis could have a profound impact on the patient's outcome. We report a case of a 77-year-old female who developed unilateral compartment syndrome in the calf after staged bilateral TKA at an outside clinic. The patient presented with medical complications related to compartment syndrome: rhabdomyolysis and myoglobinuria, which caused acute renal failure. Thus, we performed late fasciotomy one week after symptom onset to debride necrotic tissue and salvage the compartment. In the discussion section, we will discuss risk factors for compartment syndrome after TKA, results of late fasciotomy and other indications for surgical treatment of compartment syndrome.

    Peripheral neuropathies are a frequent, but often underdiagnosed, cause of pain and functional impairment. The clinical symptoms can be subtle, and other neurologic or non neurologic clinical entities are often evoked. MRI and ultrasonography are the imaging modalities of choice for depicting nerves and assessing neuropathies. Common neuropathies in the knee area involve the saphenous, the tibial, the common peroneal and the sural nerves. The most frequent mechanisms of nerve injury in this area are nerve entrapment and nerve stretching. A perfect knowledge of the normal imaging anatomy is essential for accurate assessment of neuropathies. In this article, we will review the anatomy of the nerves around the knee, and their normal and pathological appearance.

Peroneal arteria magna (PAM) is one such vascular abnormality that may preclude the use of the graft due to the high risk of lower-limb ischemia. Lower-limb angiography is the standard for assessing the lower-limb vascular anatomy; however, the indications remain controversial. Although balloon occlusion has been used to assess the vascular supply in distal bypass surgery, there have no reported cases of balloon occlusion to assess the viability of the distal extremity with PAM. Intraoperative assessment of vascular anatomy with an aborted harvest can lead to significant morbidity and cost. Balloon occlusion provides a relatively safe and minimally invasive technique for assessment of potential lower-limb ischemia in patients with PAM.

    We investigated the association between the development of deep venous thrombosis (DVT) and calf vein diameter in patients with acute hemorrhagic stroke. We measured the maximum diameter of paralytic side posttibial veins (PTVs) and peroneal veins (PVs) in 49 patients with intracerebral hemorrhage on admission and at 2 weeks after stroke onset by ultrasonography. We also examined for the presence or absence of DVT, and then analyzed the association of DVT with the maximum vein diameter. At 2 weeks after stroke, DVTs were detected in PTVs in 7 patients and in PVs in 6 patients. The maximum calf vein diameters at 2 weeks were significantly greater in patients with DVT compared with those without DVT (PTV, P = .033; PV, P = .015). Although calf vein diameter at admission did not influence the future incidence of DVT in patients with intracerebral hemorrhage, the presence of DVT was associated with calf vein dilatation.

The aim of this study was to define the optimal management for asymptomatic patients with colorectal cancer and unresectable liver metastases. Patients and methods: Patients receiving elective surgery (n = 17 were compared to patients receiving chemotherapy only (n = 31. Data concerning patients' demographics, location of primary tumor, comorbidities, performance status, Child–Pugh score, extension of liver metastases, size of primary, and other secondary locations were collected. Results: Thirty-day mortality after chemotherapy was lower than that after surgical resection (19.3% versus 29.4%; not significant. In patients with >75% hepatic involvement, mortality at 1 month was higher after receiving surgical treatment than after chemotherapy alone (50% versus 25%. In patients with <75% hepatic involvement, 30-day mortality was similar in both groups (not significant. Thirty-day mortality in patients with Stage T3 was lower in those receiving chemotherapy (16.7% versus 30%; not significant. Overall survival was similar in both groups. The risk of all-cause death after elective surgery (2.1 was significantly higher than in patients receiving chemotherapy only (P = 0.035. Conclusion: This study demonstrated that in palliative treatment of asymptomatic unresectable Stage

The Masculine Inventory of the Self-concept Gender Schemas was used to classify the sample into typological groups, and the Running Anaerobic Sprint Test was used to measure the physiological parameters (speed, acceleration, strength, and power and the fatigue index. The study sample was composed of 64 male professional futsal players who competed in the National Indoor Soccer league in 2013; the subjects had an average weight of 76.00±6.7 kg. Among the athletes studied, 23 (35.9% were classified as heteroschematic female, 22 (34.4% as heteroschematic male, and 19 (29.7% as isoschematic. Regarding their positions on the court, eleven were goalkeepers (17.2%, 13 (20.3% were defenders, 28 (43.8% were midfielders, and 12 (18.8% were attackers. The players had similar weights even when belonging to different typological groups and having different positions in the court. However, it is worth noting that male heteroschematic players had a greater mean weight (77.11±5.93 kg and that the goalkeeper was, on average, the heaviest player (79.36±8.14 kg. The results of the physiological parameter analysis relative to typological group showed that, on average, high-level soccer players presented similar performance profiles in different rounds, as statistically significant differences were not found in any of the studied

Cataract surgery is the most common surgical procedure performed by ophthalmologists and is the only effective treatment for cataracts. Advances in the surgical techniques and better postoperative visual outcomes have progressively changed the primary concern of cataract surgery to become a procedure refined to yield the best possible refractive results. Sufficient mydriasis during cataract removal is critical to a successful surgical outcome. Poor pupil dilation can lead to serious sight-threatening complications that significantly increase the cost of surgery and decrease patients comfort. Mydriasis is obtained using anticholinergic and sympathomimetic drugs. Phenylephrine, an α1-adrenergic receptor agonist, can efficiently dilate the pupil when administered by intracameral injection. Additionally, nonsteroidal anti-inflammatory drugs (NSAIDs like ketorolac, which inhibit the synthesis of prostaglandins, are used to decrease intraoperative miosis, control pain and inflammation associated with cataract surgery, and to prevent the development of cystoid macular edema following surgery. Recently, a new combination of phenylephrine and ketorolac (Omidria® has been approved by United States Food and Drug Administration for use during cataract surgery to maintain intraoperative mydriasis, prevent miosis, and reduce postoperative pain and inflammation. Clinical trials have shown that this new combination is effective

    Full Text Available Previously, we demonstrated i that ergocalciferol (vitamin D2 increases axon diameter and potentiates nerve regeneration in a rat model of transected peripheral nerve and ii that cholecalciferol (vitamin D3 improves breathing and hyper-reflexia in a rat model of paraplegia. However, before bringing this molecule to the clinic, it was of prime importance i to assess which form - ergocalciferol versus cholecalciferol - and which dose were the most efficient and ii to identify the molecular pathways activated by this pleiotropic molecule. The rat left peroneal nerve was cut out on a length of 10 mm and autografted in an inverted position. Animals were treated with either cholecalciferol or ergocalciferol, at the dose of 100 or 500 IU/kg/day, or excipient (Vehicle, and compared to unlesioned rats (Control. Functional recovery of hindlimb was measured weekly, during 12 weeks, using the peroneal functional index. Ventilatory, motor and sensitive responses of the regenerated axons were recorded and histological analysis was performed. In parallel, to identify the genes regulated by vitamin D in dorsal root ganglia and/or Schwann cells, we performed an in vitro transcriptome study. We observed that cholecalciferol is more efficient than ergocalciferol and, when delivered at a high dose (500 IU/kg/day, cholecalciferol induces a significant locomotor and electrophysiological recovery. We also demonstrated that cholecalciferol increases i the number of preserved or newly formed axons in the proximal end, ii the mean axon diameter in the distal end, and iii neurite myelination in both distal and proximal ends. Finally, we found a modified expression of several genes involved in axogenesis and myelination, after 24 hours of vitamin supplementation. Our study is the first to demonstrate that vitamin D acts on myelination via the activation of several myelin-associated genes. It paves the way for future randomised controlled clinical trials for peripheral
