    Muscle anomalies around the wrist, in particular the palmaris longus muscle, may cause effort-related median nerve compression. A search of the medical records at our university hospital between 1994 and 1999 revealed four patients with an effort-related median nerve compression due to a reversed palmaris longus muscle. Magnetic resonance imaging was used in the patient work-up and showed an anomalous muscle in each case that had been missed initially. All four patients were free of pain after simple excision of the anomalous muscle. Awareness of muscle anomalies at the wrist on MR imaging is essential in evaluating patients with nerve compressions at the wrist. The purpose of this article is to heighten this awareness in radiologists. (orig.)

  2. ANATOMICAL VARIATION OF PALMARIS LONGUS: TENDINOUS ORIGIN AND FLESHY INSERTION

    Buddhadeb Ghosh

    2015-03-01

    Full Text Available A tendinous origin and fleshy insertion of palmaris longus muscle was observed in the left forearm during routine dissection which was performed on adult male cadaver in the department of Anatomy, Dr. Rajendra Prasad Government Medical College. It was having long tendinous origin from the medial epicondyle of the humerus and the surrounding deep fascia. It was fusiform at the lower middle of the forearm. The fleshy muscular insertion was noted to the flexor retinaculum and few muscular fibers interdigitate with flexor carpi ulnaris muscle and palmar aponeurosis. The length of tendon was 19 inches and fleshy muscular length was 11inches. The median nerve and ulnar nerve was covered by this fleshy insertion. This palmaris longus variation is helpful for the surgeon and the radiologist, orthopaedic, plastic surgeon during any diagnosis of the forearm because this fleshy part of muscle can compress the median nerve and ulnar nerve or it can be mistaken as a tumor or ganglion during radiological or clinical examination.

    Full Text Available The palmaris longus is considered a phylogenetic degenerate metacarpophalangeal joint flexor muscle in humans, a small vestigial forearm muscle; it is the most variable muscle in humans, showing variation in position, duplication, slips and could be reverted. It is frequently studied in papers about human anatomical variations in cadavers and in vivo, its variation has importance in medical clinic, surgery, radiological analysis, in studies about high-performance athletes, in genetics and anthropologic studies. Most studies about palmaris longus in humans are associated to frequency or case studies, but comparative anatomy in primates and comparative morphometry were not found in scientific literature. Comparative anatomy associated to morphometry of palmaris longus could explain the degeneration observed in this muscle in two of three of the great apes. Hypothetically, the comparison of the relative length of tendons and belly could indicate the pathway of the degeneration of this muscle, that is, the degeneration could be associated to increased tendon length and decreased belly from more primitive primates to those most derivate, that is, great apes to modern humans. In conclusion, in primates, the tendon of the palmaris longus increase from Lemuriformes to modern humans, that is, from arboreal to terrestrial primates and the muscle became weaker and tending to be missing.

    2012-01-01

    Abstract Objectives: Palmaris longus (PL) is frequently used as a donor tendon in various wrist, hand and reconstructive surgery. It is believed that PL is a dispensable muscle that can be harvested without producing any func- tional loss at the donor hand. The purpose of this study is to compare the grip strength between normal subjects having the tendon and lacking it. Methods: Three hundred thirty three male subjects between 18 and 25 years of age were assessed for the presence of th...

  5. Use of adjunctive palmaris longus abductorplasty (Camitz) tendon transfer in pediatric median nerve injury.

    Baluch, Narges; Borschel, Gregory H

    2013-05-01

    A number of tendon transfers have been described for opponensplasty. Transfer of the palmaris longus (PL) tendon with a palmar fascial extension was initially described by Camitz. This technique has mostly been combined with carpal tunnel release in patients with long standing median neuropathy with atrophy of the thenar muscles. However, the Camitz transfer has not been previously described in the setting of pediatric median nerve injury. We report 4 cases of Camitz transfer in pediatric patients with median nerve injuries. Four children (all female; age range 3-15 yrs) underwent PL tendon transfer following median nerve injury. The causes of injury included trauma, iatrogenic injury, and neuritis of the brachial plexus. The Camitz procedure was performed at the time of median nerve decompression and/or reconstruction. All patients had excellent early return of function. Transfer of the palmaris longus tendon reliably restores palmar abduction, with minimal to no additional morbidity, in carefully selected pediatric patients with median nerve injury undergoing release of the carpal tunnel.

    2011-01-01

    Full Text Available Background : The knowledge of Palmaris longus (PL is a growing interest for its wide role in reconstructive plastic surgeries as a donor tendon for transfer or transplant. The prevalence of the PL agenesis has been well-documented by many authors in different ethnic groups or populations. Many conventional tests for determining the presence of the PL has been described, but lamentably there are many discrepancies in confirming its presence or absence. Slight modifications of the prevailing methods can still give authenticate results. Aim : This prospective study was conducted to determine the incidence of unilateral and bilateral agenesis of PL and its association with sex and side of the limb in the Andhra population of India. Materials and Methods : A total of 942 subjects of both sexes belonging to 18-23 years were used to access the PL using various tendon examination techniques including our modified Schaeffer′s test. The data collected were analyzed by Pearsons χ2 test using SPSS software. Results : Overall agenesis of muscle in both sexes was 264 (28.0%, out of which 40.2% was seen in females and 14.7% in males with the ratio of 3:1. The unilateral agenesis was seen in 70.5% and bilateral agenesis in 29.5% subjects. The left side agenesis was seen in 51.6% and right side in 48.4% subjects. Conclusions : The prevalence of bilateral and unilateral agenesis was more common on left side with a greater likelihood in the female subjects. The proposed technique could bring better results in all subjects and can be implemented in manual examination of PL.

    2011-06-01

    The radial forearm free flap with palmaris longus tendon provides a good functional lip with a reasonable aesthetics in our patient. The patient was satisfied with the result and there were no functional complaints such as drooling reported by him. We think that this flap could be a flap of choice for reconstruction of the large, full thickness lip defects.

  10. A Case of Reverse Palmaris Longus Muscle- An Additional Muscle in the Anterior Compartment of the Forearm

    Bhat, Ashwini Lagadamane Sathynarayana; Gadahad, Mohandas Rao Kappettu

    2016-01-01

    It is uncommon to have additional muscles in the upper limb. Some of them may restrict the movements or compress the nerves and vessels, while others may go unnoticed. During the routine dissection for undergraduate medical students, we observed an additional muscle in the anterior compartment of the forearm in about 60-year-old male cadaver. The muscle had a prominent belly and a long tendon. Distally, it was attached to the flexor retinaculum by a short and thick tendon. Proximally, long tendon of the muscle passed between the flexor carpi ulnaris and palmaris longus and was attached to the common aponeurosis shared by the extensor carpi ulnaris and flexor digitorum profundus muscles. The additional muscle belly was supplied by a branch from the anterior interosseous nerve. The ulnar nerve and artery was passing deep to the fleshy belly of the muscle. The muscle reported here might compress the ulnar nerve and artery and may produce neurovascular symptoms. On the other hand, the tendon and fleshy belly of the muscle could be useful in muscle/tendon grafts. The observations made by us in the present case will supplement our knowledge of variations of the muscles in this region which could be useful for surgeons during the forearm and hand surgeries.

  12. Prophylactic decompression of extensor pollicis longus to prevent rupture

    Navaratnam, A V; Ball, S; Eckersley, R

    2013-01-01

    We present a case of a patient with spontaneous rupture of right extensor pollicis longus (EPL) tendon, who had also developed left wrist pain and weakness in his left EPL that MRI studies confirmed to be caused by tendinosis. Subsequently, decompression of left EPL and reconstruction of right EPL with palmaris longus tendon graft was undertaken. In this case, decompression of the left EPL tendon led to resolution of the patient's symptoms as well as preventing tendon rupture. We advocate the...

  13. Rerouting extensor pollicis longus tendon transfer.

    Colantoni Woodside, Julie; Bindra, Randip R

    2015-04-01

    Following radial nerve palsy, loss of the extensor pollicis longus (EPL), abductor pollicis longus and extensor pollicis brevis tendons results in loss of thumb extension and radial abduction. Multiple tendon transfers are described to address the loss of thumb extension following radial palsy utilizing the palmaris longus or flexor digitorum sublimis transferred to the EPL tendon. Owing to its ulnar vector of pull, the EPL tendon is a secondary adductor of the thumb, and in order to mitigate the tendency for thumb adduction, the EPL tendon is divided at the wrist and brought subcutaneously to the radial side of the wrist for repair to the donor tendon to improve the line of pull for the donor tendon. We describe the use of a technique to reroute the EPL tendon through the first compartment in a retrograde fashion prior to repair with the donor tendon on the radial side of the wrist. The use of the first dorsal compartment provides a pulley to maintain the position of the transfer and to prevent potential bowstringing of the tendon as wrist flexion and thumb extension are attempted. because the repair is performed proximal to the extensor retinaculum, the donor tendon length is not compromised. Because the tendon is redirected through the first dorsal compartment and inserts into the distal phalanx, a single transfer attempts to restores both thumb extension and radial abduction.

    2011-04-01

    Full Text Available Flexor digitorum longus is one of the muscles of posterior compartment of leg. This paper primarily focuses on the variation of flexor digitorum longus muscle of leg. Sixty inferior extremities were dissected. A small muscle taking origin from the tendon of flexor digitorum longus was observed. Some of the fibers were originating from the fascia covering the flexor digitorum longus and tibialis posterior. Its tendon merged with the tendon of flexor digitorum longus going to second digit in sole of foot and quadratus plantae. Nerve supply of this muscle was from a small branch of tibial nerve from its undersurface. Supernumerary muscles in the ankle joint or nearby region can be a factor of compression in tarsal tunnel syndrome. MRI is the modality of choice in diagnosing accessory muscles. Functional and clinical significance is important not only for the anatomist and clinicians but also for the pathologists and sports people.

    Conclusion: Results of this study showed that grip strength is similar whether the subject has or does not have a PL. Patients may be informed that harvesting their PL tendon would not affect the functions of their hands. [Hand Microsurg 2012; 1(1.000: 7-9

  17. Flexor Digitorum Accessorius Longus: Importance of Posterior Ankle Endoscopy

    Jorge Pablo Batista

    2015-01-01

    Full Text Available Endoscopy for the posterior region of the ankle through two portals is becoming more widespread for the treatment of a large number of conditions which used to be treated with open surgery years ago. The tendon of the flexor hallucis longus (FHL travels along an osteofibrous tunnel between the posterolateral and posteromedial tubercles of the talus. Chronic inflammation of this tendon may lead to painful stenosing tenosynovitis. The aim of this report is to describe two cases depicting an accessory tendon which is an anatomical variation of the flexor hallucis longus in patients with posterior friction syndrome due to posterior ankle impingement and associated with a posteromedial osteochondral lesion of the talus. The anatomical variation (FDAL described was a finding during an endoscopy of the posterior region of the ankle, and we have spared it by sectioning the superior flexor retinaculum only. The accessory flexor digitorum longus is an anatomical variation and should be taken into account when performing an arthroscopy of the posterior region of the ankle. We recommend this treatment on this type of injury although we admit this does not make a definite conclusion.

  18. Calcifications simulating peroneus longus tendinitis

    In two patients with sprains of the ankle joint calcification adjacent to the posterior tibial margin was evident in the lateral projection of a standard radiographic examination. Calcifying peroneus longus tendinitis was suggested. Further tangential views and computed tomography (CT) scan disclosed, however, that the calcifications in both patients were located in the tibial insertion of the posterior and inferior tibio-fibular ligament. In such cases, a correct diagnosis will avoid unnecessary treatment for a non-existent tendinitis. (orig.)

In this report we present a discussion of the morphological significance and phylogenetic history of one such muscle observed. In this case report we describe an anomalous calf muscle which extends from the popliteal region, runs along the posterior compartment of the leg, reaches the sole and is inserted to the flexor digitorum longus muscle. This kind of muscle variations are considered to be the higher origin of the flexor digitorum accessorius muscle of the sole. Here we discuss the phylogenetic history of this muscle as this muscle variant is present in some primitive mammals, absent in apes and in this particular case appeared as one of the muscles of the flexor compartment of the leg.

    2010-10-01

    Full Text Available Deep muscles of the posterior compartment of the leg constitute of the flexor hallucis longus, flexor digitorum and tibialis posterior. During the routine dissection of a 53-year-old male cadaver of Indian origin, an accessory muscle was observed in the posterior compartment of the both the legs, deep to the soleus muscle. The muscle originated as a slender tendon from the medial border of the tibia, led to a small belly of the muscle fibers arranged bipinnately and converged into another slender tendon. The tendon got inserted at the second toe in the left foot, after joining both the slip of the flexor hallucis longus and the flexor digitorum longus muscle tendon in the sole. In the right leg, the accessory muscle tendon was inserted to the calcaneus with fibrous attachments to the quadratus plantae, flexor hallucis longus and the flexor digitorum longus. The present case will facilitate in interpretation of the medial side swelling of the leg, tarsal tunnel syndrome or pain due to muscle entrapment, by the radiologists surgeons and orthopedists.

    Objective The flexor digitorum accessorius longus muscle (FDAL), an anomalous muscle about the ankle, has recently been implicated in tarsal tunnel syndrome. The purpose of this study is to document the prevalence of the FDAL, its MR appearance and its relation to the neurovascular bundle in the tarsal tunnel. Design and patients The prevalence of the FDAL was determined from 100 ankle MR examinations in asymptomatic individuals. The appearance of the FDAL was summarized from 20 examples of FDAL: six gathered from the asymptomatic group and 14 acquired from a group of randomly collected cases of patients with ankle complaints. Results The prevalence of the FDAL was 6%, calculated from the group of 100 asymptomatic individuals. Possessing a dominant fleshy component in the tarsal tunnel, the FDAL accompanies the posterior neurovascular bundle as it descends the ankle. Conclusion The FDAL is encountered in 6% of asymptomatic individuals. Its prominent fleshy component in the tarsal tunnel and its close proximity to the posterior tibial neurovascular bundle readily differentiate the FDAL from other medial anomalous muscles on MR imaging.

  11. Fibre type composition of female longus capitis and longus colli muscles.

    Miller, Alexandra; Woodley, Stephanie J; Cornwall, Jon

    2016-03-01

    Effective management of neck pain requires detailed knowledge of cervical muscle structure and function. Information on muscle fibre type assists in determining function; few data exist on the fibre type composition of many cervical muscles. The purpose of this study was to investigate the fibre type composition of longus capitis (LCa) and longus colli (LCo) to provide a better understanding of their function. Muscle sections were harvested unilaterally from LCa (C2-C7) and LCo (C3, C6, T1) in seven female cadavers (mean age 86 ± 9 years). Immunohistochemistry was used to identify type I and type II fibres, and stereology (random systematic sampling) used to determine fibre numbers. Data were assessed using descriptive statistics and one-way ANOVA (significance P < 0.05). Fifty-two sections were assessed (82,785 fibres; mean 1,592 ± 927 per section). LCa had a significantly greater proportion of type I fibres than LCo (64.3 % vs 55.7 %, P = 0.011). The percentage of fibre types varied significantly between individuals in LCa, but not LCo. No significant difference was found in the proportion of type I fibres between cervical levels for either LCa or LCo. LCa and LCo appear functionally different in elderly females, with LCa potentially having a more postural role (higher type I fibre proportion). Fibre types were homogenous throughout each muscle, indicating that contractile function is similar across the length of individual muscles. Further studies across a larger age-span and in males are required to determine whether results are representative of other populations. PMID:25794488

  12. Painful accessory navicular

    Lawson, J.P.; Ogden, J.A.; Sella, E.; Barwick, K.W.

    1984-11-01

    The accessory navicular is usually considered a normal anatomic and roentgenographic variant. The term may refer to two distinct patterns. First, a sesamoid bone may be present within the posterior tibial tendon (Type 1); this is anatomically separate from the navicular. Second, an accessory ossification center may be medial to the navicular (Type 2). During postnatal development this is within a cartilaginous mass that is continuous with the cartilage of the navicular. At skeletal maturity the accessory center usually fuses with the navicular to form a curvilinear bone. The Type 2 pattern may be associated with a painful foot, particularly in the athletic adolescent, and should not be arbitrarily dismissed as a roentgenologic variant in the symptomatic patient. The clinical, radiologic, pathologic, and surgical findings in ten cases are reviewed. Roentgenographically the ossicle is triangular or heartshaped. sup(99m)Tc MDP imaging may be of value when the significance of the ossicle is uncertain. Even when the roentgenographic variant is bilateral, increased radionuclide activity occurs only on the symptomatic side. Histologic examination of surgically excised specimens reveals inflammatory chondro-osseous changes in the navicular-accessory navicular synchondrosis compatible with chronic trauma and stress fracture. Nonsurgical treatment with orthotics or cast immobilization produces variable results and resection of the accessory navicular may be the treatment of choice.

Nonsurgical treatment with orthotics or cast immobilization produces variable results and resection of the accessory navicular may be the treatment of choice. (orig.)

  14. Scapholunate stabilization with dynamic extensor carpi radialis longus tendon transfer.

    Peterson, Steven L; Freeland, Alan E

    2010-12-01

    Dynamic extensor carpi radialis longus tendon transfer to the distal pole of the scaphoid acts synchronously and synergistically with wrist motion to restore the slider crank mechanism of the scaphoid after scapholunate interosseous ligament (SLIL) injury. The procedure is designed to simulate a hypothetical dorsal radioscaphoid ligament that more closely approximates the normal viscoelastic forces acting on the scaphoid throughout all phases of wrist motion than does the static checkrein effect and motion limitations of capsulodesis or tenodesis. Extensor carpi radialis longus transfer may be independently sufficient to support normal or near-normal scapholunate and midcarpal kinematics and prevent further injury propagation in patients with partial SLIL tears and dynamic scapholunate instability. Extensor carpi radialis longus transfer alone may improve carpal congruity in patients with static scapholunate instability, but SLIL and dorsal lunate ligament repair or reconstruction is essential for favorable durable outcomes. Extensor carpi radialis longus transfer offers a simple and reasonable alternative to capsulodesis or tenodesis to support these ligament repairs or reconstructions, does not require intercarpal fixation, and allows rehabilitation to proceed expeditiously at approximately 1 month after surgery.

    A neurilemmoma of the spinal accessory nerve extending from the lower brain stem to the high cervical region, without typical jugular foramen syndome is presented. Preoperative diagnosis is difficult but should be considered in the differential diagnosis of a high cervical intradural extramedullary lesion in patients with lower cranial nerve(s) dysfunction. The value of intrathecal and intravenous contrast enhancement computed tomography (CT) myelogram is emphasized. 13 refs.; 3 figs

  17. Ultrasonographic features of an adductor longus tear: case report

    Muscle strain of the lower extremities is among the most common injuries in sports. Excessive force, rather than direct trauma, causes disruption of the muscle-tendon unit, usually at the myotendinous junction, and improper rest and rehabilitation of a minor strain can often lead to a far more disabling injury. High-resolution ultrasonography is useful for direct imaging of muscle injuries. We present a case where ultrasonography was used to detect, treat and follow-up an adductor longus tear in a soccer player. (author)

    Accessory breast is an ectopic breast tissue from developmental remnants. It sometimes begins to make symptom, pain and swelling, during premenstrual period or pregnancy. For it has been known as a rear condition, it has occasionally misdiagnosed as a abnormal mass, such as lymphadenitis or hidradentis. We have analyzed 52 accessory breast tissues prospectively, to document the characteristic findings of accessory breast. In summary, the characteristic sonographic findings of accessory breast were the presence of breast tissue superficial to the axillary fascia or underlying fascia if not in axilla, resembling the patient's own breast pattern, the presence of converging appearance of dilated ducts, presence of nipple and/or areola, the obliteration of inner wall of dermis, the obliteration of subcutaneous fat layer, and the downward displacement of axillary fascia or underlying fascia if not in axilla without interruption.

  3. Keratoderma-like T cell dyscrasia: A report of 13 cases and its distinction from mycosis fungoides palmaris et plantaris

    Cynthia M Magro

    2016-01-01

    Full Text Available Background: Atypical epitheliotropic T cell lymphocytic infiltrates are commonly encountered in routine and consultative dermatopathology practices and typically do not represent mycosis fungoides. Other conditions can mimic certain light microscopic and phenotypic findings encountered in mycosis fungoides, comprising a diverse spectrum of conditions including the lymphomatoid drug reaction, collagen vascular disease, viral hypersensitivity reactions and cutaneous T cell dyscrasia. Aims: To examine biopsies obtained from cutaneous T cell dyscrasia localized to the palms and soles and to evaluate whether it exhibits a morphologic and pathogenetic continuum with mycosis fungoides plantaris et palmaris. Methods: We examined 13 biopsies showing an epidermotropic superficial lymphocytic infiltrate from thirteen patients who presented with a palmar and/or plantar keratoderma without other sites of cutaneous involvement. Conventional light microscopy, immunophenotyping and clonality studies were carried out. The clinical features were recorded. Results: Biopsies showed a variably dense, superficial, angiocentric CD4 or CD8 dominant lymphocytic infiltrate accompanied by a non-destructive pattern of epidermotropism. Low-grade cerebriform atypia along with variable diminution in the expression of CD7 and CD62L was noted. In three cases, statins were suspected to be the cause. Due to lack of familiarity with the entity, treatment interventions were inconsistent and not aggressively pursued. There was no evidence of disease progression to mycosis fungoides in any case. Limitations: The limitations of this study include the lack of long-term follow up and information on the nature of the therapeutic interventions and responses to treatment. Conclusion: The spectrum of cutaneous lymphoid dyscrasias should be expanded to include cases manifesting as palmo-plantar keratoderma. These cases are to be distinguished from mycosis fungoides palmaris et plantaris. As

    1995-11-01

    With mandates and regulatory policies to meet both the California Air Resources Board (CARB) and the Partnership for a New Generation of Vehicles (PNGV), designing vehicles of the future will become a difficult task. As we look into the use of electric and hybrid vehicles, reduction of the required power demand by influential automobile components is necessary in order to obtain performance and range goals. Among those automobile components are accessories. Accessories have a profound impact on the range and mileage of future vehicles with limited amounts of energy or without power generating capabilities such as conventional vehicles. Careful assessment of major power consuming accessories helps us focus on those that need improvement and contributes to attainment of mileage and range goals for electric and hybrid vehicles.

  8. Extensor Pollicis Longus Rupture after Mini TightRope Suspensionplasty.

    Seetharaman, Mani; Vitale, Mark A; Desai, Kapil; Crowe, John F

    2016-05-01

    Background Arthritis of the first carpometacarpal (CMC) joint has been surgically treated in multiple ways with varying levels of success as measured by subjective and objective measures. Trapeziectomy with numerous variations in suspensionplasty comprises one of the more commonly used surgical procedures. Recently, the Mini TightRope apparatus has been utilized as a new method for achieving suspensionplasty, and as such lacks significant review of use and safety in the literature. Case Description An extensor pollicis longus (EPL) rupture following a trapeziectomy and Mini TightRope suspensionplasty for CMC arthritis of the thumb is presented. The patient successfully underwent an extensor indicis proprius (EIP) to EPL transfer to treat this complication. Literature Review There is well-established documentation of injury to the extensor tendons from orthopedic hardware such as volar locking plates. Regarding use of the Mini TightRope apparatus, guidelines for placement of the suture button include caution to place the button away from the EPL tendon to minimize the chance of tendon irritation. Additionally, FiberWire sutures, a component of the apparatus, have been shown to demonstrate soft tissue reactions with adjacent inflammatory response. Published reports on adverse events utilizing this device have been limited to case reports including an index metacarpal fracture. Clinical Relevance The aim of this case report was to cite an occurrence of EPL rupture following its use and discuss the possibilities of its direct contribution. PMID:27104081

We report two large pedigrees in which accessory navicular is inherited in an autosomal dominant fashion with incomplete penetrance.

  15. The accessory fallopian tube: A rare anomaly

    Kusum R Gandhi

    2012-01-01

    Full Text Available This paper presents a rare anatomical variation in the form of accessory fallopian tube on right side. The duplication of fallopian tube was observed in a 34-year-old female during routine undergraduate dissection in our department. Fallopian tube is the part of uterus that carries the ovum from the ovary to the uterus. Accessory fallopian tube is the congenital anomaly attached to the ampullary part of main tube. This accessory tube is common site of pyosalpinx, hydrosalpinx, cystic swelling and torsion. The ovum released by the ovary may also be captured by the blind accessory tube leading to infertility or ectopic pregnancy. Hence, all patients of infertility or pelvic inflammatory disease should be screened to rule out the presence of accessory fallopian tube and if encountered should be removed.

    2015-01-01

    We present a rare case of carcinoma developing in an accessory breast. The patient presented with a progressive lump in her right axilla for 1 year. On examination, there was a well-developed nipple areola complex in the right axilla overlying a hard, fixed 5 × 3 cm lump. On investigation, core biopsy revealed poorly differentiated carcinoma of the breast. Mammography also revealed features of a malignant lesion with skin and muscle infiltration. Neoadjuvant chemotherapy was administered followed by modified radical mastectomy after three cycles. Immunohistochemistry study showed positive status of oestrogen and progesterone receptors, and negative HER-2 neu. Three more cycles of chemotherapy along with 50 Gy radiotherapy were given in an adjuvant setting followed by hormone therapy. PMID:26260957

    Only a few cases of adductor longus tendon ruptures have been reported in the literature and - there are no clear criteria for conservative or surgical treatment. A case of traumatic rupture of the right distal adductor longus tendon is presented in an elite soccer player, which was surgically repaired. The condition was managed conservatively primarily. However, after 2 months, a palpable mass remained on the medial side of the thigh, and the patient had pain after moderate everyday load and insufficient strength of the right leg during physical exercise. It was decided to explore ruptured tendon surgically and reattach to the femur. Full function of the right leg was achieved at 3 months after surgical repair. At 6 months postoperatively, the patient had returned to soccer at the same level. PMID:27132783

  19. Truncated dystrophins reduce muscle stiffness in the extensor digitorum longus muscle of mdx mice

    Hakim, Chady H.; Duan, Dongsheng

    2012-01-01

    Muscle stiffness is a major clinical feature in Duchenne muscular dystrophy (DMD). DMD is the most common lethal inherited muscle-wasting disease in boys, and it is caused by the lack of the dystrophin protein. We recently showed that the extensor digitorum longus (EDL) muscle of mdx mice (a DMD mouse model) exhibits disease-associated muscle stiffness. Truncated micro- and mini-dystrophins are the leading candidates for DMD gene therapy. Unfortunately, it has never been clear whether these t...

  1. Evaluation of the neuromuscular compartments in the peroneus longus muscle through electrical stimulation and accelerometry

    Guillermo A. Mendez

    2013-10-01

    Full Text Available BACKGROUND: Muscles are innervated exclusively by a nerve branch and possess definite actions. However, mammalian skeletal muscles, such as the trapezius, the medial gastrocnemius, and the peroneus longus, are compartmentalized. In the peroneus longus muscle, multiple motor points, which innervate individual neuromuscular compartments (NMC, the superior (S-NMC, anteroinferior (AI-NMC, and posteroinferior (PI-NMC, have been described. The contribution of each neuromuscular compartment to the final action of the muscle is fundamental for the rehabilitation of patients afflicted by neurological and muscle dysfunctions. Interventions are often based on electrical principles that take advantage of the physiological characteristics of muscles and nerves to generate therapeutic effects. OBJECTIVE: To compare the effects of stimulating the different neuromuscular compartments (NMCs of the peroneus longus muscle on the motor threshold (MT and acceleration of the foot. METHOD: This is a cross-sectional study comprising 37 subjects. The three NMCs of the peroneus longus muscle were stimulated, and the acceleration of the foot and the motor threshold of each NMC were evaluated. A repeated measures analysis of variance with Bonferroni corrections of two intra-subjects factors was performed. RESULTS: The stimulation of the different NMCs did not result in any differences in MT (F=2.635, P=0.079. There were significant differences between the axes of acceleration caused by the stimulation of the different NMCs (F=56,233; P=0.000. The stimulation of the posteroinferior compartment resulted in the greatest acceleration in the X-axis (mean 0.614; standard deviation 0.253. CONCLUSIONS: The posteroinferior compartment primarily contributes to the eversion movement of the foot. NMCs have specific functional roles that contribute to the actions of the muscles to which they belong.

    2010-01-01

    Abstract The melanocortin receptor family consists of 5 members which belong to the GPCR superfamily. Their specific ligands, the melanocortins are peptide hormones which are formed by the proteolytic cleavage of the proopiomelanocortin (POMC) protein. It is now recognised that certain GPCRs require accessory proteins for their function. Like these GPCRs the melanocortin receptor family is also known to be associated with accessory proteins that regulate their function. ...

  5. ACCESSORY SPLEEN: A CLINICALLY RELEVANT ANATOMIC ANOMALY

    2016-02-01

    Full Text Available The purpose of our study is to emphasize on the clinical relevance of the presence of accessory spleen. It is not only a well-documented anatomic anomaly, it holds special significance in the differential diagnosis of intra-abdominal tumours and lymphadenopathy. MATERIALS AND METHODS Thirty male cadavers from North Indian population above the age of 60 yrs. were dissected in the Anatomy Department of FMHS, SGT University, Gurgaon, over a period of 5 yrs. (Sep 2010-Aug 2015 and presence of accessory spleen recorded. Tissue from the accessory spleen was also subjected to routine histological processing and slide prepared by haematoxylin and eosin staining. RESULTS Accessory spleen was present in two cadavers near the splenic hilum. One was 3.9 cm in the long axis and weighed about 48.4 grams, while the other was 1.2 cm in long axis and weighed about 12.5 grams. One had a separate arterial branch from the main splenic artery; that it was splenic tissue was confirmed histologically. DISCUSSION The presence of accessory spleen is considered to be due to embryonic non-fusion of the splenic aggregate with the main mass. CONCLUSION Though accessory spleen in itself pose no clinical problems, its significance cannot be undermined. Surgeons and radiologists are advised to look for and rule out the presence of accessory spleen, especially while evaluating a case of abdominal and perineal pathology, else it may be wrongly diagnosed as malignant tumour or enlarged lymph node leading to grave consequences.

    Accessory parotid gland tumors are relatively rare; hence, adequately detailed clinical analyses of these tumors are difficult to perform at a single institution. In this report, we describe the findings for 65 patients [29 men, 36 women; median age, 51 (9-81) years] with accessory parotid gland tumors, consisting of 4 cases documented by us and 61 cases previously reported by other Japanese authors. Approximately 50% of the patients were treated in an otolaryngology department, while the remaining patients were treated in plastic surgery, oral surgery, or dermatology departments. In 4 patients, the results of preoperative fine-needle aspiration cytology indicated that the tumor was benign; however, the postoperative histopathology results revealed malignant tumors. The frequencies of malignant and benign tumors were 44.6% (n = 29) and 55.4% (n = 36), respectively. Mucoepidermoid carcinoma and pleomorphic adenoma were the most frequent types of malignant and benign accessory parotid gland tumors, respectively. Among the various surgical methods that were used, such as direct cheek and intraoral incisions, a standard parotidectomy incision was the most preferred treatment approach for these tumors. Recently, an endoscopic approach has also been found to yield satisfactory results. An optimal approach should be selected after evaluating the advantages and disadvantages of these methods. No definite guidelines are available regarding the choice of elective neck dissection and postoperative radiation therapy for malignant accessory parotid gland tumors. Although tumor resection (plus elective neck dissection) and postoperative radiation therapy have been frequently performed for various kinds of malignant accessory parotid gland tumors to date, additional studies are needed regarding the criteria for selecting elective neck dissection and postoperative radiation therapy. Since the malignancy rate for accessory parotid gland tumors is higher than that for parotid gland

  7. Neuroanatomy and clinical analysis of the cervical sympathetic trunk and longus colli.

    2015-11-01

    Anterior cervical surgery is commonly used for cervical vertebral body lesions. However, the structure of blood vessels and nerve tissues along the route of anterior cervical surgery is complex. We aimed to measure the data of the longus colli, the sympathetic trunk and the cervical sympathetic trunk (CST) ganglia in Chinese cadaver specimens. A total of 32 adult cadavers were studied. We delineated the surgical anatomy of the CST. The superior and inferior/cervicothoracic ganglia of the sympathetic trunk consistently appeared. The middle ganglion was observed in 28.1% of the specimens and there were 2 cases of unilateral double middle cervical ganglia. The inferior ganglion was observed in 25.0% of the specimens and the cervicothoracic ganglion was observed in the remaining specimens. The distance between the CST gradually decreased from the top to the bottom, and the distance between the medial edges of the longus colli gradually broadened from the top down. The average angle between the bilateral CST and the midline of the vertebra was 11.2°±1.8° on the left side and 10.3°±1.4° on the right side. The average angle between the medial margins of longus colli of both sides was 11.1°±1.9°. The CST is at high risk when LC muscle is cut transversely or is dragged heavily, especially at the levels of C6 and C7. Awareness of the regional anatomy of the CST could help surgeons to identify and preserve it during anterior cervical surgeries. PMID:26668584

  8. Cuboid oedema due to peroneus longus tendinopathy: a report of four cases

    O' Donnell, Paul; Saifuddin, Asif [Royal National Orthopaedic Hospital NHS Trust, Department of Radiology, Stanmore, Middlesex (United Kingdom)

    2005-07-01

    To highlight focal bone abnormality in the cuboid due to tendinopathy of the adjacent peroneus longus. A retrospective review was carried out of the relevant clinical and imaging features. Two male and two female patients were studied, mean age 51.5 years (range 32 - 67 years), referred with foot pain and imaging showing an abnormal cuboid thought to represent either tumour or infection. A long history of foot pain was usual with a maximum of 8 years. Radiographs were normal in two cases and showed erosion in two, one of which exhibited periosteal new bone formation affecting the cuboid. Bone scintigraphy was undertaken in two patients, both of whom showed increased uptake of isotope. MRI, performed in all patients, showed oedema in the cuboid adjacent to the peroneus longus tendon. The tendon and/or paratendinous tissues were abnormal in all cases, but no tendon discontinuity was identified. One patient possessed an os peroneum. Unequivocal evidence of bone erosion was seen using MRI in three patients, but with greater clarity in two cases using CT. Additional findings of tenosynovitis of tibialis posterior, oedema in the adjacent medial malleolus and synovitis of multiple joints in the foot were seen in one patient. Imaging diagnosis was made in all cases avoiding bone biopsy, but surgical exploration of the peroneal tendons was performed in two cases and biopsy of ankle synovium in one. Oedema with erosion of the cuboid bone, simulating a bone lesion (cuboid ''pseudotumour''), may be caused by adjacent tendinopathy of peroneus longus. It is vital to be aware of this entity to avoid unnecessary biopsy of the cuboid. (orig.)

  9. Accessory breast tissue mimicking pedunculated lipoma.

    Husain, Musharraf; Khan, Sabina; Bhat, Ashraf; Hajini, Firdoos

    2014-01-01

    Accessory breast tissue is an uncommon condition which occurs in 0.4-6% of women. It is mostly located in the axilla where it can cause diagnostic difficulty, especially if it is unilateral and large. Usually it is bilateral and presents as an asymptomatic mass during pregnancy or lactation. The diagnosis of ectopic breast tissue is important as it can undergo the same pathological changes that occur in a normal breast, such as mastitis, fibrocystic disease and carcinoma. We present a case of a large right-sided accessory breast in a 32-year-old woman that was clinically diagnosed as pedunculated lipoma. However, subsequent histopathological examination proved it to be an accessory breast tissue with lactational changes. PMID:25006058

  10. Variant course of extensor pollicis longus tendon in the second wrist extensor compartment.

    Kim, Young Jun; Lee, Jae Hoon; Baek, Jong Hun

    2016-05-01

    Among the muscles involved in thumb movement, the extensor pollicis longus (EPL) tendon of the hand is considered the most consistent structure with the least variation among individuals. There have been a few reports regarding different types of supernumerary tendons; however, an abnormal course of the EPL tendon is extremely rare. We describe a case of a variant course of a single EPL tendon appearing in the second extensor compartment of the wrist. This case was observed incidentally during wrist surgery, and demonstrates a unique variation of tendon course, which has not been reported previously. The knowledge of this anatomic variation is helpful in surgical planning and for making accurate diagnoses. PMID:26253859

  12. Ultrasound and Electromyography Guidance for Injection of the Longus Colli With Botulinum Toxin for the Treatment of Cervical Dystonia.

    Allison, Stephen K; Odderson, Ib R

    2016-09-01

    Cervical dystonia, also called spasmodic torticollis, is a painful condition in which neck muscles contract involuntarily, and may cause abnormal head position or movements. The primary (or first line of) treatment of cervical dystonia is chemodenervation with injection of botulinum toxin into the affected muscles. We report a case of a young man with idiopathic cervical dystonia who developed anterocollis (forward flexion of the neck) not responsive to prior scalene and sternocleidomastoid muscle injections. To safely access the deeper cervical musculature, ultrasound (US) was used in conjunction with electromyography, to inject the longus colli muscles bilaterally. The patient responded well and had no complications. The longus colli has been reported to be injected using electromyography, fluoroscopy, computed tomography, and, less frequently, US. We propose that US guidance is an excellent technique for botulinum toxin injection, especially for deep cervical muscles such as the longus colli. PMID:26886108

  2. Non‑Azygos Accessory Fissure in Right Upper Lobe Associated with Superior and Inferior Accessory Fissures in Right Lower Lobe

    Thomas Jose Eluvathingal Muttikkal; Chunli Deng

    2012-01-01

    Accessory fissures in the lungs are common congenital variations, usually detected as incidental findings in radiographs or CT scan. Accessory fissures can act as an anatomic barrier to the spread of inflammatory or neoplastic disease, as well as due to the variant anatomy, mimic lesions. It is important to recognize the presence of accessory fissures, as they affect surgical planning of pulmonary lobectomy and segmentectomy. Accessory fissure in the right upper lobe other than due to the ano...

  3. Catalase-positive microperoxisomes in rat soleus and extensor digitorum longus muscle fiber types

    Riley, Danny A.; Bain, James L. W.; Ellis, Stanley

    1988-01-01

    The size, distribution, and content of catalase-reactive microperoxisomes were investigated cytochemically in three types of muscle fibers from the soleus and the extensor digitorum longus (EDL) of male rats. Muscle fibers were classified on the basis of the mitochondrial content and distribution, the Z-band widths, and the size and shape of myofibrils as the slow-twitch oxidative (SO), the fast-twitch oxidative glycolytic (FOG), and the fast-twitch glycolytic (FG) fibers. It was found that both the EDL and soleus SO fibers possessed the largest microperoxisomes. A comparison of microperoxisome number per muscle fiber area or the microperoxisome area per fiber area revealed following ranking, starting from the largest number and the area-ratio values: soleus SO, EDL SO, EDL FOG, and EDL FG.

  4. Flexor pollicis longus repair in a patient with Linburg-Comstock anomaly: A case report

    Mehmet Unal

    2016-08-01

    Results: At the end of the rehabilitation program, the thumb recovered full range of motion, and physical examination revealed synchronous flexion movement (synkinesis of the thumb and index finger. Conclusion: Flexor pollicis longus tendon lacerations are common in the clinical practice of hand surgeons. Making a separate proximal wrist incision is a very useful technique to reach a proximal tendon stump. Otherwise, aggressive maneuvers may cause additional damage to the tendons involved and result in unpredicted outcomes. The attempts to retrieve the tendon at the injury site resulted in failure and gave a tethering sensation to the surgeon who recalled the Linburg-Comstock anomaly.

  5. Closed traumatic rupture of the flexor pollicis longus tendon in zone T I: a case report.

    Uekubo, Kazuaki; Itoh, Soichiro; Yoshioka, Taro

    2015-01-01

    A healthy 41-year-old male suffered a direct blow on the palmar side of his right thumb when folding a table, which slipped along his thumb until it was stopped at the inter-phalangeal (IP) joint, resulting in a complete rupture of the flexor pollicis longus (FPL) tendon in zone T I. The proximal tendon stump was passed through the oblique pulley, fixed to the base of the distal phalanx with a pull-out wire technique and augmented on it using a part of the distal tendon remnant. After removal of the cast and the pull-out wire three weeks postoperatively, range of motion exercise was initiated and good functional recovery was obtained. PMID:25609290

  6. Alternative delivery of male accessory gland products

    Zizzari, Z Valentina; Smolders, Irene; Koene, Joris M

    2014-01-01

    To increase fertilization success, males transfer accessory gland products (Acps). Several species have evolved unconventional Acps transfer modes, meaning that Acps are transferred separately from the sperm. By surveying the sperm-free Acps transfer cases, we show that these animals have evolved a common strategy to deliver Acps: they all inject Acps directly through the partner’s body wall into the hemolymph. Our review of this mode of Acps transfer reveals another striking similarity: they...

  9. Isolated spinal accessory neuropathy and intracisternal schwannomas of the spinal accessory nerve

    Abdullah M. Al-Ajmi

    2015-03-01

    Full Text Available We report a 40-year-old female patient presenting with isolated left spinal accessory neuropathy that developed insidiously over 6 years. She complained of ill-defined deep neck and shoulder pain. On examination, prominent sternocleidomastoid and trapezoid muscle weakness and atrophy, shoulder instability, and lateral scapular winging were observed. MRI identified a small mass of the cisternal portion of the spinal accessory nerve. Its appearance was typical of schwannoma. Surgical treatment was not offered because of the small tumor size, lack of mass effect and the questionable functional recovery in the presence of muscular atrophy.

  10. Imaging of the symptomatic type Il accessory navicular bone

    Accessory ossicles of the foot are commonly mistaken for fractures. The accessory navicular is one of the most common accessory ossicles of the foot. There is a higher incidence in women and the finding might be bilateral in 50-90%. This entity is usually asymptomatic, although populations with medial foot pain have a higher prevalence. Three types of accessory navicular bone have been described. The type Il accessory navicular is the most commonly symptomatic variant with localized chronic or acute on chronic medial foot pain and tenderness with associated inflammation of overlying soft tissues. Plain radiographic identification of the accessory navicular is insufficient to attribute symptomatology. Ultrasound allows for comparison with the asymptomatic side and localization of pain. Bone scintigraphy has a high sensitivity but positive findings lack specificity. Magnetic resonance imaging is of high diagnostic value for demonstrating both bone marrow and soft tissue oedema.

  13. Accessory slips of the extensor digiti minimi.

    Li, Jing; Mao, Qing Hua

    2014-01-01

    During the educational dissection of a 69-year-old Chinese male cadaver, an extensor digiti minimi (EDM) with five slips on the right hand was discovered. Except for the two slips of the little finger, the two radial slips were inserted into the dorsal aponeurosis of the middle finger and the ring finger, respectively. The middle slip was connected to the junctura tendinum in the fourth intermetacarpal spaces. Variations in this region are of paramount importance for the reconstructive surgeons, who may utilize the accessory slips to restore functional capacity of the fingers. PMID:24970007

    2008-04-15

    We present our experience in the diagnosis of extensor pollicis longus tendon tears using different imaging methods. In the past 2 years, 12 patients (7 males, 5 females) with extension deficit of distal phalanx of thumb were diagnosed with extensor pollicis longus tendon (EPL) rupture by means of different imaging methods. The ultrasound pattern consisted of a gap between tendon stumps occupied by a continuous (eight cases) or discontinuous (four cases) attenuated hypoechoic string. In nine cases, the tendon ends were identified as a thickened stump-like structure. In the other three cases, tendon stumps were attenuated and mixed with atrophic muscle or wrist subcutaneous fat. All ultrasound findings were confirmed by CT, MR and/or surgical findings.

  15. Attritional rupture of extensor pollicis longus: a rare complication following elastic stable intramedullary nailing of a paediatric radial fracture.

    2011-01-01

    Elastic stable intramedullary nail fixation has become established as an acceptable method of treatment for diaphyseal fractures of both forearm bones in the paediatric population. It is considered safe, minimally invasive and does not compromise physeal growth. We report a case of delayed rupture of extensor pollicis longus due to attrition over the sharp edges of a protruding nail end after elastic stable intramedullary nailing of a paediatric radial diaphyseal fracture.

  18. The influence of passive stretch on the growth and protein turnover of the denervated extensor digitorum longus muscle.

    Goldspink, D F

    1978-08-15

    At 7 days after cutting the sciatic nerve, the extensor digitorum longus muscle was smaller and contained less protein than its innervated control. Correlating with these changes was the finding of elevated rates of protein degradation (measured in vitro) in the denervated tissue. However, at this time, rates of protein synthesis (measured in vitro) and nucleic acid concentrations were also higher in the denervated tissue, changes more usually associated with an active muscle rather than a disused one. These anabolic trends have, at least in part, been explained by the possible greater exposure of the denervated extensor digitorum longus to passive stretch. When immobilized under a maintained influence of stretch the denervated muscle grew to a greater extent. Although this stretch-induced growth appeared to occur predominantly through a stimulation of protein synthesis, it was opposed by smaller increases in degradative rates. Nucleic acids increased at a similar rate to the increase in muscle mass when a continuous influence of stretch was imposed on the denervated tissue. In contrast, immobilization of the denervated extensor digitorum longus in a shortened unstretched state reversed most of the stretch-induced changes; that is, the muscle became even smaller, with protein synthesis decreasing to a greater extent than breakdown after the removal of passive stretch. The present investigation suggests that stretch will promote protein synthesis and hence growth of the extensor digitorum longus even in the absence of an intact nerve supply. However, some factor(s), in addition to passive stretch, must contribute to the anabolic trends in this denervated muscle. PMID:708412

  20. Anomalous bilateral contribution of extensor pollicis longus and muscle fusion of the first compartment of the wrist

    2016-04-01

    Full Text Available Knowledge of the anatomical variations of the muscles of the first dorsal compartments of the wrist is clinically relevant to De Quervain's tenosynovitis and to reconstructive surgeries. In the literature, there are many reports of the presence of multiple insertion tendons in the first dorsal compartment of the wrist, but few reports describe occurrences of fusion and muscle contributions. This case report describes an anomalous bilateral contribution of the extensor pollicis longus. This anomalous contribution was found through a slender auxiliary tendon that crossed laterally under the extensor retinaculum, entered the first dorsal compartment of the wrist and merged with the tendon of the extensor pollicis brevis muscle. In the same cadaver in which this contribution was present, there was atypical muscle fusion of the abductor pollicis longus muscle and extensor pollicis brevis muscle. In conclusion, anomalous bilateral contribution of the extensor pollicis longus muscle and atypical muscle fusion, concomitant with a variant insertion pattern, are the highlight of this case report. Furthermore, it is concluded that additional tendons may be effectively used in reconstructive surgeries, but that there is a need for knowledge of the possible numerical and positional variations of these tendons, with a view to making more effective surgical plans.

  2. Calcific Tendonitis of the Longus Colli Muscle: A Noninfectious Cause of Retropharyngeal Fluid Collection

    Ronak Rahmanian

    2014-01-01

    Full Text Available Calcific tendonitis of the longus colli (CTLC muscle is an underrecognized cause of spontaneous acute or subacute neck pain, dysphagia, or odynophagia. Imaging may reveal a retropharyngeal fluid collection leading to the presumed diagnosis of retropharyngeal abscess. Recognition of this uncommon presentation is important to prevent unnecessary surgical incision and drainage. A 44-year-old otherwise healthy male presented with a 2-week history of progressive neck pain, stiffness, and odynophagia. A noncontrast CT scan of the cervical spine revealed a retropharyngeal fluid collection with a small area of calcification anterior to C2. There was a presumed diagnosis of retropharyngeal abscess. The patient was afebrile with normal vital signs. Flexible nasolaryngoscopy was unremarkable. C-reactive protein was elevated but all other bloodwork was normal with no evidence of an infective process. A CT scan was repeated with IV contrast showing no enhancement around the fluid collection. A diagnosis of CTLC was made. The patient was successfully managed with a short course of intravenous steroids and oral NSAIDs with complete resolution of symptoms. Clinically CTLC can mimic more serious disease processes. Identifying pathognomonic imaging findings often confirms the diagnosis. Awareness of this condition by the otolaryngologist will ensure proper patient management and avoidance of unnecessary procedures.

  3. Amylin evokes protein p20 phosphorylation and insulin resistance in rat skeletal muscle extensor digitorum longus

    LEE; Shaochin(李晓钦); Garth; Cooper

    2002-01-01

    In the present study, we investigate effect of amylin on the insulin sensitivity of rat skeletal muscle extensor digitorum longus (EDL) using in vitro intact muscle incubation in combination with metabolic radioactive labeling. The molecular basis of the amylin action was further examined using proteomic analysis. In particular, proteins of interest were characterized using an integrated microcharacterization procedure that involved in-gel trypsin digestion, organic solvent extraction, high performance liquid chromatography separation, microsequencing and microsequence analysis. We found that amylin significantly decreased the insulin-stimulated glucose incorporation into glycogen (p < 0.01) and produced a protein spot of approximately 20 ku in size. This amylin responsive protein (hereby designated as amylin responsive protein 1, APR1) was identified to be protein p20. Moreover, ARP1 spots on gels were found to consistently produce a corresponding radioactive spot on X-ray films in 32Pi but not in 35S-methionine labeling experiments. In conclusion, our results showed that in vitro amylin concomitantly evoked the production of ARP1 and caused insulin resistance in EDL muscle. It is suggested that protein p20 may be involved in amylin signal transduction and the appearance of ARP1 may be a step in a molecular pathway leading to the development of insulin resistance. ARP1 might therefore be a useful molecular marker for amylin action, insulin resistance and Type 2 diabetes.

    Mayer, Robert W.; Silva, Frank A.

    1977-01-01

    An electrical cable accessory includes a generally tubular member of elastomeric material which is to be installed by placement over a cylindrical surface to grip the cylindrical surface, when in appropriate assembled relation therewith, with a predetermined gripping force established by dilation of the tubular member, the installation being facilitated by introducing fluid under pressure, through means provided in the tubular member, between the tubular member and the cylindrical surface, and simultaneously impeding the escape of the fluid under pressure from between the tubular member and the cylindrical surface by means adjacent one of the ends of the tubular member to cause dilation of the tubular member and establish a fluid layer between the tubular member and the cylindrical surface, thereby reducing the gripping force during installation.

  10. Transfer of either index finger extensor tendon to the extensor pollicis longus tendon

    Meads, Bryce M; Bogoch, Earl R

    2004-01-01

    BACKGROUND: Extensor pollicis longus (EPL) tendon ruptures have been treated succesfully with the transfer of the extensor indicis proprius (EIP) tendon. Situations exist in which, due to intraoperative observations, another tendon transfer may be considered preferable to the standard EIP transfer method. OBJECTIVES: To determine whether transfer of the extensor digitorum communis II (EDC II) tendon from the index finger to the EPL tendon, leaving the EIP tendon to the index finger intact, would serve as an equally efficient transfer and not adversely affect the function of the hand. METHODS: Two patients who had the EDC II tendon transferred to the ruptured EPL tendon, and two patients who had the EIP tendon transferred, were retrospectively reviewed. In each transfer type, one patient had suffered an EPL tendon rupture after a Colles’ fracture, and the other had rheumatoid arthritis. The rupture occurred on the non-dominant side in one patient in each transfer type. Each patient was examined and subjected to range of motion and power testing at least one year following surgery. RESULTS: All four patients showed a minimal extension lag with the lift off test, but there was no noticeable difference in range of motion, pinch grip and hand grip strength between the transfer types. Both EDC II transfer patients demonstrated an 8° to 15° loss of thumb interphalangeal joint flexion compared with the unoperated side; EIP transfer patients demonstrated less than a 5° loss. Three patients demonstrated a minor extension lag in the index finger and middle finger. Extension power of the thumb and index finger in all patients varied with wrist flexion and extension and ranged from 50% to 150% of the unoperated side. CONCLUSIONS: These case reports suggest that either index finger tendon may be successfully transferred in EPL tendon ruptures. PMID:24115870

  11. The association of hallux limitus with the accessory navicular.

    Evans, R D Lee; Averett, Ryan; Sanders, Stephanie

    2002-06-01

    Hallux limitus is one of the most prevalent, debilitating disorders of the first metatarsophalangeal joint, and it has many proposed etiologies. This article reviews these etiologies, focusing primarily on the pes planus foot. The pes planus foot type is often associated with symptomatic hallux limitus and the accessory navicular. This article discusses this correlation, although a causal relationship has not been proven. The prevalence and classification of the accessory navicular are also discussed. Clinical cases involving symptomatic hallux limitus occurring concomitantly with an accessory navicular are reviewed, including radiographic findings, symptoms, and surgical treatment. PMID:12070237

    2012-01-01

    Full Text Available A case of accessory scrotum in a 1-year-old boy is reported because of its rarity. A boy presented with a tumor mass attached with scrotum-like skin on its tip in the right side of perineum between the scrotum and anus. Both testes had descended into the scrotum. There was no other urological anomaly. Histological findings of the tumor indicated perineal lipoma, and the scrotum-like portion accessory scrotum. An overview of sequences during the normal development of male external genitalia has been provided and the deranged mechanism resulting in this anomaly has been reviewed with hypothesis regarding etiology of accessory scrotum.

  13. Variations in abductor pollicis longus and extensor pollicis brevis tendons in the Quervain syndrome: a surgical and anatomical study.

    2007-01-01

    Eighty-two wrists of Thai cadavers and the wrists of 66 patients with de Quervain syndrome were studied, and the variation in the number of tendons and the fibro-osseous tunnel in the first extensor compartment were recorded. The abductor pollicis longus had more than one tendon in 73 of the cadavers (89%) and in 32 of the patients (49%) (p de Quervain syndrome (p = 0.01). The results indicate that the number of fibro-osseous tunnels and multiple compartments in the first extensor compartment may be associated with a predisposition to de Quervain syndrome.

    Invaginations of the liver by the diaphragm form accessory fissures that may mimic the major hepatic fissures on sectional images. Accessory fissures are most common in the superior right hepatic lobe. Their average incidence on computed tomographic (CT) scans is 25%. Their frequency increases with age, approaching 70% in the seventh and eighth decades. Their depth may equal or exceed 2 cm in one-third of cases. Multiple accessory fissures may mimic pathologic liver nodules on CT and may be associated with diaphragmatic scalloping or eventration on the chest film. When only parts of these fissures are seen sonographically, they may be mistaken for echogenic liver lesions. The differentiation of accessory fissures from the major hepatic fissures, from pathologic lesions, and from sonographic pseudofissure artifacts is discussed.

    Shyam Sundar Krishnan; Sivaram Bojja; Madabhushi Chakravarthy Vasudevan

    2015-01-01

    Schwannomas are benign lesions that arise from the nerve sheath of cranial nerves. The most common schwannomas arise from the 8 th cranial nerve (the vestibulo-cochlear nerve) followed by trigeminal and facial nerves and then from glossopharyngeal, vagus, and spinal accessory nerves. Schwannomas involving the oculomotor, trochlear, abducens and hypoglossal nerves are very rare. We report a very unusual spinal accessory nerve schwannoma which occupied the fourth ventricle and extended inferior...

  5. Mammographic appearance of accessory breast tissue in the axilla

    Objective: To observe the mammographic appearance of accessory breast tissue in the axilla. Methods: In the past 3 years, 7562 women were underwent bilateral screen-film mammography. All of the mediolateral oblique (MLO) films were reviewed retrospectively to look for whether there was accessory breast tissue and what the mammographic features were like. Radiographically the accessory tissue resembled the main normal breast glandular tissue but was separated from it. Results: Of the 7652 case, accessory breast tissue in the axilla was detected in 161 cases. The prevalence was 2%. The age ranged from 17 to 70 years (mean, 39 years). 38% of them were found in the bilateral axilla, 42% only in the right, and 20% only in the left. The dimensions on the right ranged from 0.7 to 8.0 cm (mean, 3.5 cm), and that on the left ranged from 1.0 to 7.0 cm (mean, 3.3 cm). There were four types among the accessory breast tissue: patchy type was the most (35%), then the branched type (26%), mixed type (20%), and mass-like type (19%). 3 cases were proved by pathology. Conclusion: It is important that the radiologist be familiar with the mammographic appearance of accessory breast tissue in the axilla in order that they could be distinguished from other pathological changes

    2007-11-01

    Full Text Available Abstract Background To assess the prevalence of and relation between rupture or tenosynovitis of the Flexor Hallucis Longus (FHL tendon and range of motion, deformities and joint damage of the forefoot in RA patients with foot complaints. Methods Thirty RA patients with painful feet were analysed, their feet were examined clinically for the presence of pes planus and range of motion (ROM, radiographs were scored looking for the presence of forefoot damage, and ultrasound examination was performed, examining the presence of tenosyovitis or rupture of the FHL at the level of the medial malleolus. The correlation between the presence or absence of the FHL and ROM, forefoot damage and pes planus was calculated. Results In 11/60(18% of the feet, a rupture of the FHL was found. This was associated with a limited motion of the MTP1-joint, measured on the JAM (χ2 = 10.4, p = 0.034, a higher prevalence of pes planus (χ2 = 5.77, p = 0.016 and a higher prevalence of erosions proximal at the MTP-1 joint (χ2 = 12.3, p = 0.016, and joint space narrowing of the MTP1 joint (χ2 = 12.7, p = 0.013. Conclusion Rupture of the flexor hallucis longus tendon in RA-patients is associated with limited range of hallux motion, more erosions and joint space narrowing of the MTP-1-joint, as well as with pes planus.

    2000-09-01

    To evaluate the angiographic anatomy of the accessory left gastric artery (accLGA). We evaluated the angiographic findings of the accLGA in 50 patients (Angiostar; Siemens, Erlangen, Germany). Performing celiac and selective angiography in 50 and 34 patients, respectively. By means of celiac angiography, (1) site of origin, (2) anatomical course, (3) diameter, (4) degree of tortuosity, and (5) distal tapering were evaluated, while selective angiography was used to determine (1) arterial branching, (2) area of blood supply, and (3) patterns of gastric wall stain. Celiac angiography showed that the accLGA arose from the left hepatic artery (LHA) in 45 cases (90%) and from the proper hepatic artery in five (10%). If the accLGA arose from the LHA, its origin entirely depended on the branching pattern of the latter. It always arose from the lateral branch of the LHA furthest to the left and uppermost, and proximal to its umbilical point. The most common anatomical course of the accLGA, seen in 27 cases (54%), was between the S2 and S3 segmental branch. The diameter and degree of tortuosity of the accLGA were similar to those of adjacent intrahepatic branches in 21 (42%) and 33 cases (66%), respectively. The degree of tapering was less than that of adjacent intrahepatic vessel in 28 (56%). Selective angiography demonstrated esophageal branching of the acc LGA in 27 cases (79%), inferior phrenic arterial branching in three (9%), a mediastinal branch in one (3%), and hypervascularity of the lung in one (3%). In 15 cases (44%), bifurcation of the accLGA was recognized. The vascular territory of the accLGA was the gastric fundus together with the distal esophagus in 21 cases (62%), mainly the gastric fundus in six (18%), and mainly the distal esophagus in four (12%). The pattern of gastric mucosal stain was curvilinear wall in 31 cases (91%) and nodular in three (9%). A knowledge of the angiographic anatomy of the accLGA facilitates accurate recognition of this artery on

  10. Antidromic Atrioventricular Reciprocating Tachycardia Using a Concealed Retrograde Conducting Left Lateral Accessory Pathway.

    Gonzalez, Jaime E; Zipse, Matthew M; Nguyen, Duy T; Sauer, William H

    2016-03-01

    Atrioventricular reciprocating tachycardia is a common cause of undifferentiated supraventricular tachycardia. In patients with manifest or concealed accessory pathways, it is imperative to assess for the presence of other accessory pathways. Multiple accessory pathways are present in 4% to 10% of patients and are more common in patients with structural heart disease. In rare cases, multiple accessory pathways can act as the anterograde and retrograde limbs of the tachycardia. PMID:26920167

  15. [Radiofrequency ablation of accessory pathways in pre-excitation syndrome].

    Pfeiffer, D; Tebbenjohanns, J; Jung, W; Manz, M; Lüderitz, B

    1993-04-16

    Various parameters relating to the radio-frequency ablation of accessory pathways were studied in 53 patients (27 males, 26 females: mean age 38.5 [14-64] years) with a history of paroxysmal tachycardia (over 1 month to 50 years), shown to be caused by an accessory pathway (Wolff-Parkinson-White syndrome). In all patients the following values were obtained: (1) number of procedures necessary to achieve permanent blockage of the accessory pathway (1-4); (2) duration of each procedure (45-420 min); (3) duration of fluoroscopy (5-102 min); (4) number of necessary radio-frequency applications (1-48); and (5) cumulative energy per procedure. To ablate left-lateral pathways (n = 10) required fewer procedures, shorter duration per procedure, shorter fluoroscopy time, fewer current applications and less total energy than coagulation of right-sided pathways (n = 10). Those various parameters were greatest for ablation of septal and para-septal pathways (n = 9). Pathways which conducted only retrogradely (n = 15) were more difficult to ablate than those with anterograde conduction (n = 38). There were two complications. In one case a tension pneumothorax occurred after faulty puncture of the subclavian vein; in the other, the left ventricle was perforated causing an acute tamponade which required pericardiocentesis with subsequent suture closure of the perforation. It is concluded that, in principle, all accessory pathways, regardless of their conduction potential and site, can be ablated by a radio-frequency current. PMID:8472633

  16. Cancer of the accessory breast - a case report

    Breast neoplasm may develop in ectopically located glandular tissue. This paper presents an interesting and rare case of a 50-year-old female who despite regular mammography screening examination developed an invasive accessory breast cancer. Clinical examination revealed a 2 cm - tumour localized 4 cm below the left infra mammary fold. The lesion was immobile, the skin and the atrophic nipple were retracted, the tumour infiltrated the thoracic wall. Oligo biopsy and additional examinations showed an invasive stage IIIB ductal breast cancer (Bloom II, G-2). The receptor status was: ER(+), PGR(+), HER2(-). The increased level of cancer antigen 15.3 was found. The patient was submitted to pre-operative chemotherapy. She also underwent surgery and subsequently post-operative chemotherapy and radiotherapy. On the basis of the presented case, it could be concluded that the accessory mammary glands are out of the image of screening breast examinations. Accessory breast cancer is usually diagnosed by clinical examination and ultrasonography. Preventive resection of accessory breast in women at high risk of developing breast cancer can be considered as the treatment of choice in most patients. (authors)

  20. Extensor pollicis brevis tendon can hyperextend thumb interphalangeal joint in absence of extensor pollicis longus: Case report and review of the literature

    Strauch, Robert J; Strauch, Carolyn B

    2016-01-01

    We are reporting a case of extensor pollicis longus tendon rupture which did not require tendon transfer owing to the ability of the intact extensor pollicis brevis (EPB) to fully hyperextend the thumb interphalangeal joint. The thumb metacarpophalangeal joint was also able to be fully actively extended by the EPB. Previous anatomical studies have demonstrated that the insertional anatomy of the EPB tendon is highly variable and sometimes inserts onto the extensor hood and distal phalanx, which is likely the mechanism by which our patient was able to fully extend the thumb interphalangeal joint. Despite the potential for the EPB to extend the IP joint of the thumb, virtually all previously reported cases of extensor pollicis longus (EPL) tendon rupture had deficits of thumb IP extension requiring tendon transfer. This case highlights the potential ability of the EPB tendon to completely substitute for the function of the EPL tendon in providing thumb IP joint extension. PMID:27458556

    2010-01-01

    Biomechanical simulations of tendon transfers performed following tetraplegia suggest that surgical tensioning influences clinical outcomes. However, previous studies have focused on the biomechanical properties of only the transferred muscle. We developed simulations of the tetraplegic upper limb following transfer of the brachioradialis (BR) to the flexor pollicis longus (FPL) to examine the influence of residual upper limb strength on predictions of post-operative transferred muscle functi...

  3. EMG and force production of the flexor hallucis longus muscle in isometric plantarflexion and the push-off phase of walking

    Peter, Annamaria; Hegyi, Andras; Stenroth, Lauri; Finni Juutinen, Taija; Cronin, Neil

    2015-01-01

    Large forces are generated under the big toe in the push-off phase of walking. The largest flexor muscle of the big toe is the flexor hallucis longus (FHL), which likely contributes substantially to these forces. This study examined FHL function at different levels of isometric plantarflexion torque and in the push-off phase at different speeds of walking. FHL and calf muscle activity were measured with surface EMG and plantar pressure was recorded with pressure insoles. FHL activity was comp...

    Chiu, N.-T.; Jou, I.-M.; Lee, B.-F.; Yao, W.-J.; Tu, D.-G.; Wu, P.-S

    2000-05-01

    AIM: The accuracy of bone scintigraphy in diagnosing symptomatic accessory navicular bones has not been well studied. We conducted a retrospective study to explore the results and use of scintigraphy in symptomatic and asymptomatic accessory navicular bones. MATERIALS AND METHODS: Thirteen patients with a total of 13 symptomatic and 10 asymptomatic accessory navicular bones were included in the study. We used a scoring system to grade the scintigraphic abnormalities. The patients' symptoms and scintigraphic findings were recorded. RESULTS: Though focally increased radiopharmaceutical uptake was observed in all symptomatic accessory naviculars, half of the asymptomatic accessory navicular bones had the same manifestations. The scoring system was of no value in differentiating symptomatic from asymptomatic accessory navicular bones. CONCLUSION: Bone scintigraphy is a sensitive but not a specific tool for diagnosing a symptomatic accessory navicular. Chiu, N.-T. (2000)

    Full Text Available Schwannomas are benign lesions that arise from the nerve sheath of cranial nerves. The most common schwannomas arise from the 8 th cranial nerve (the vestibulo-cochlear nerve followed by trigeminal and facial nerves and then from glossopharyngeal, vagus, and spinal accessory nerves. Schwannomas involving the oculomotor, trochlear, abducens and hypoglossal nerves are very rare. We report a very unusual spinal accessory nerve schwannoma which occupied the fourth ventricle and extended inferiorly to the upper cervical canal. The radiological features have been detailed. The diagnostic dilemma was due to its midline posterior location mimicking a fourth ventricular lesion like medulloblastoma and ependymoma. Total excision is the ideal treatment for these tumors. A brief review of literature with tabulations of the variants has been listed.

    Das, Somdipto; Nayak, Umanath K; Buggavetti, Rahul; Sekhar, Shobana

    2016-05-01

    The accessory parotid gland is salivary gland tissue separated from the main gland at a variable distance. This gland is histologically similar to the main gland, but has a higher incidence of malignant neoplasms than the main gland. Regarding the various malignant neoplasms, studies have shown higher incidences of mucoepidermoid carcinoma, with less than 2% being adenoid cystic carcinoma. We present a case of swelling in the midcheek region that, after clinical examination, was diagnosed as a case of neoplasm of the accessory parotid gland. On the basis of auxiliary investigations including intraoperative frozen section, it was concluded that it was adenoid cystic carcinoma, grade I, and after wide surgical resection, the tumor was removed without undergoing superficial parotidectomy. The patient received postoperative radiotherapy (RT) and was followed for 14 months without any recurrence or substantial facial asymmetry. PMID:26851989

    2015-12-01

    This study evaluated the outcomes of extensor indicis proprius (EIP) transfer based on varying degrees of thumb extension after EIP transfer and elongation of the EIP. A total of 24 cases with extensor pollicis longus (EPL) ruptures who underwent EIP to EPL transfer were analyzed prospectively. The EIP transfer was performed with neutral wrist positioning. In group I (12 cases), EIP and EPL were sutured on the thumb in neutral state at interphalangeal joint, and the mean EIP elongation of this group measured 0.2 cm (range, -0.5 to 0.5 cm). In group II (12 cases), EIP and EPL were sutured on the thumb in full extension state at interphalangeal joint, and the mean EIP elongation measured 0.7 cm (range, 0.5-1.5 cm). The mean follow-up period was 13.5 months. The 2 groups were compared based on thumb motion, grip strength, pinch power, and the Disabilities of the Arm, Shoulder, and Hand questionnaire score. Extension of the thumb at the interphalangeal joint was -5.2° in group I and 7.2° in group II, demonstrating statistically significant differences. No significant differences were found between the 2 groups in other parameters. In EIP transfer, thumb in extension after transfer and EIP elongation is recommended for restoring thumb extension at the interphalangeal joint. PMID:26418770

  10. Effects of chronic administration of clenbuterol on contractile properties and calcium homeostasis in rat extensor digitorum longus muscle.

    Pascal Sirvent

    Full Text Available Clenbuterol, a β2-agonist, induces skeletal muscle hypertrophy and a shift from slow-oxidative to fast-glycolytic muscle fiber type profile. However, the cellular mechanisms of the effects of chronic clenbuterol administration on skeletal muscle are not completely understood. As the intracellular Ca2+ concentration must be finely regulated in many cellular processes, the aim of this study was to investigate the effects of chronic clenbuterol treatment on force, fatigue, intracellular calcium (Ca2+ homeostasis and Ca2+-dependent proteolysis in fast-twitch skeletal muscles (the extensor digitorum longus, EDL, muscle, as they are more sensitive to clenbuterol-induced hypertrophy. Male Wistar rats were chronically treated with 4 mg.kg-1 clenbuterol or saline vehicle (controls for 21 days. Confocal microscopy was used to evaluate sarcoplasmic reticulum Ca2+ load, Ca2+-transient amplitude and Ca2+ spark properties. EDL muscles from clenbuterol-treated animals displayed hypertrophy, a shift from slow to fast fiber type profile and increased absolute force, while the relative force remained unchanged and resistance to fatigue decreased compared to control muscles from rats treated with saline vehicle. Compared to control animals, clenbuterol treatment decreased Ca2+-transient amplitude, Ca2+ spark amplitude and frequency and the sarcoplasmic reticulum Ca2+ load was markedly reduced. Conversely, calpain activity was increased by clenbuterol chronic treatment. These results indicate that chronic treatment with clenbuterol impairs Ca2+ homeostasis and this could contribute to the remodeling and functional impairment of fast-twitch skeletal muscle.

    An accessory navicular bone (ANB) is present in 10-30% of normal feet. A morphological classification of ANB on the basis of the radiographic appearance distinguishes three types. Most symptomatic ANBs are of type 2. Although the diagnosis and treatment of sprained ankle are generally straightforward, together with an ANB, it might be misdiagnosed as a fracture. We present a 20-year-old male with type 2 ANB who was misdiagnosed as navicular fracture following sprained ankle. Turk J Phys Med...

  13. Accessory Nerve Schwannoma Containing Multiple Calcifed Foci: Unusual Presentation

    Leila Aghaghazvini

    2009-01-01

    Full Text Available "nIntroduction: Schwannomas are benign neural tumors which arise from the nerve sheath. Schwannomas of the accessory nerve are rare lesions. The clinical presentation of cranial nerve XI schwannomas relates to their location and extent: intracranial, jugular foramen, upper neck, or cervical spine. The extra cranial form is the least common reported. Calcified accessory schwannoma is rare. These lesions most often occur in the third to sixth decades of life. These tumors are slightly more common in women. "nCase presentation: We present a 37-year-old woman with a painless right posterior neck space mass which gradually appeared during one year. Except for mild numbness of the overlying skin of the mentioned mass, there were no other associated symptoms. Examination confirmed a 25 × 18mm, firm, mobile, non tender lump in the right posterior neck. Ultrasonography revealed a 30×20 mm hypo-echoic mass with multiple calcified foci and in color Doppler mild vascularity was detected. On contrast-enhanced CT scan of the neck a 30×18mm heterogeneous enhancing mass with multiple calcified foci (on non contrast cuts was found posterior to the neck vessels and had displaced them anteriorly. No surrounding fat stranding or any other gross pathology was evident in the other neck spaces. "nAccording to the above findings, lymphadenopathy due to TB or less possibly, fungal infection, hemangioma, lymphangiomam, schwannoma were our differential diagnosis. Mass resection and histopathology revealed schwannoma of the accessory nerve with an unusual calcification presentation. No evidence of recurrence was detected after one year. "nDiscussion: The clinical presentation of cranial nerve XI Schwannomas relates to their location and extent. The interesting point of this case was the unusual manifestation of accessory nerve schwannoma, not only because of its rarity but also because of its unusual calcification presentation and symptom-free appearance.  

  14. Comparison of murine hepatic accessory cells and splenic dendritic cells

    Accessory cells are required for proliferation and antibody synthesis of B lymphocytes and proliferation of T lymphocytes in primary immune responses in vitro. The obligatory cells derived from the spleen are referred to as dendritic cells. Accessory cells were isolated from normal adult livers which were functionally interchangeable with splenic DC. Both hepatic accessory cells (AC) and splenic DC adhere firmly to plastic culture dishes or wells within 2 hr; but hepatic AC, unlike splenic DC, do not detach during 22 hr additional incubation. Hepatic AC, unlike splenic DC, are not lysed or inactivated by monoclonal antibody 33D1 and C'. Hepatic AC and splenic DC are similarly sensitive to irradiation in vivo and insensitive to irradiation in vitro. Hepatic AC are separated with cells which are predominantly phagocytic and FcR+ and contain nonspecific esterase. Both hepatic AC and splenic DC are suppressed or eliminated by activation of NK cells in vivo, a phenomenon prevented by prior elimination of NK cells

  15. The histochemical profile of the rat extensor digitorum longus muscle differentiates after birth and dedifferentiates in senescence

    M Lehnert

    2009-08-01

    Full Text Available Age dependent motor unit dedifferentiation is a key component of impaired muscle function in advanced age. Here, we tested the hypothesis that rat muscle histochemical profile during the lifespan of an individual has an age-specific pattern since comprehensive longitudinal studies of muscle differentiation after birth and dedifferentiation in advanced age are scarce. Our results show that extensor digitorum longus muscle (EDL is comprised only of two fiber types after birth, type slow-oxidative (SO and type SDH-intermediate (SDHINT, the latter being indicative for the presence of polyneuronal innervation. In contrast to the constantly growing crosssectional area of the muscle fibers, a dramatic decrease in SDH-INT proportion occurs between day 14 and 21 after birth resulting in a complete loss of fiber type SDH-INT at the age of 90 days (p<0.05. At the age of 270 days, the fiber type composition of rat EDL dedifferentiates as shown by the reappearance of the SDH-INT type with a further increase at the age of 540 days (p<0.05. These changes in histochemical fiber type spectra are brought about by fiber type conversion within the fast twich fibers. The findings of the present study provide further evidence that fiber type conversion is a basic mechanism leading to motor unit differentiation and dedifferentiation during ontogenesis. Fiber type conversion shows a distinct time specific pattern and is also characteristic for motor unit regeneration after peripheral nerve repair. Factors that influence fiber type conversion and thereby motor unit organization may provide a future therapeutic option to enhance the regenerative capacity of motor units.

  16. S1P3 receptor influences key physiological properties of fast-twitch extensor digitorum longus muscle.

    2016-06-01

    To examine the role of sphingosine 1-phosphate (S1P) receptor 3 (S1P3) in modulating muscle properties, we utilized transgenic mice depleted of the receptor. Morphological analyses of extensor digitorum longus (EDL) muscle did not show evident differences between wild-type and S1P3-null mice. The body weight of 3-mo-old S1P3-null mice and the mean cross-sectional area of transgenic EDL muscle fibers were similar to those of wild-type. S1P3 deficiency enhanced the expression level of S1P1 and S1P2 receptors mRNA in S1P3-null EDL muscle. The contractile properties of S1P3-null EDL diverge from those of wild-type, largely more fatigable and less able to recover. The absence of S1P3 appears responsible for a lower availability of calcium during fatigue. S1P supplementation, expected to stimulate residual S1P receptors and signaling, reduced fatigue development of S1P3-null muscle. Moreover, in the absence of S1P3, denervated EDL atrophies less than wild-type. The analysis of atrophy-related proteins in S1P3-null EDL evidences high levels of the endogenous regulator of mitochondria biogenesis peroxisome proliferative-activated receptor-γ coactivator 1α (PGC-1α); preserving mitochondria could protect the muscle from disuse atrophy. In conclusion, the absence of S1P3 makes the muscle more sensitive to fatigue and slows down atrophy development after denervation, indicating that S1P3 is involved in the modulation of key physiological properties of the fast-twitch EDL muscle.

  17. An anomalous accessory extensor proprius indicis muscle: A case report

    Mustafa Kurklu

    2013-12-01

    Full Text Available Variations related to tendon insertion and musculotendinous junction of the extensor proprius indicis muscle are commonly encountered. An anomalous extensor indicis proprius muscle (EIP tendon was detected in a fifty-year-old female cadaver during routine dissection of the right upper extremity. The body of tendon was initiated from the posterior ulna as a one muscle body, then continued as two separate muscle bodies and tendons and finally they were separated into two slips after passing the fourth dorsal compartment. As a radial part, it was divided into two slips at the level of the first metacarpophalangeal joint, and conjugated with the extensor pollicis longus (EPL muscle. Then, as an ulnar part, it was terminated at the radial side of the lateral band of the second metacarpophalangeal joint. Familiarity with the normal anatomy and variations of the tendons may help to prevent confusion and mistakes during tendon repairs, and tendon transfers. [Hand Microsurg 2013; 2(3.000: 122-124

  5. Accessory breast tissue in axilla masquerading as breast cancer recurrence

    Goyal Shikha

    2008-01-01

    Full Text Available Ectopic or accessory breast tissue is most commonly located in the axilla, though it may be present anywhere along the milk line. Development is hormone dependent, similar to normal breast tissue. These lesions do not warrant any intervention unless they produce discomfort, thus their identification and distinction from other breast pathologies, both benign and malignant, is essential. We report a case with locally advanced breast cancer who presented with an ipsilateral axillary mass following surgery, radiotherapy, and chemotherapy. Subsequent evaluation with excision biopsy showed duct ectasia in axillary breast tissue and the patient was continued on hormone therapy with tamoxifen.

  6. Forest haulage accessories for agricultural tractors in 1995

    This bulletin is a review of hydraulic timber cranes, forest trailers and skidding grapples and winches available on the Finnish markets in autumn 1995 as accessories for mounting onto agricultural tractors. The information is mainly based on the responses of the manufacturers and distributors to a mail questionnaire. Ten producers make timber cranes and a total of 46 crane models are presented. Nearly all the cranes can be mounted onto either the 3-point hitching device, the connecting rail of a trailer/sled, or directly onto the tractor frame. The net lifting force of the cranes varies in between 19.9 - 40.0 kNm. The maximum reach of the cranes varies between 4.3 and 9.8 m. The mechanical twin-lever system has almost entirely replaced the conventional six-lever operating type. Electro-hydraulic pre-control is included in the accessories available for many of the cranes. There are twelve producers and 37 models of forestry trailers, with eight including power transmission. All these trailers are of the bogie type. Their carrying capacity varies between 6 000 - 12 500 kilos. Five manufacturers produce six models of 3-point hitchable hydraulic skidding grabbles were listed. all are provided with a frame joint easing the job of grasping and skidding of timber. Skidding winches mountable onto the 3-point hitching device are of three producers and seven models. The tractive force varies between 28 and 60 kN. All are provided with a disc clutch

  9. Digital dermatitis of the accessory digits of dairy cows

    Celso A. Rodrigues

    2010-03-01

    Full Text Available This report characterizes the digital dermatitis (DD lesions in the accessory digits of dairy cows and presents data on the applied therapy. Fifteen Holstein cattle with DD affecting the accessory digits of the hindlimbs from four dairy farms with previous history of DD were evaluated. Lesions were excised, the wounds were sutured, and a topical application of oxytetracycline powder covered by bandaging was associated with a single parenteral administration of long acting oxytetracycline IM (20mg/kg. Tissue samples were obtained for histopathology and transmission electronic microscopy (TEM. Lesions from all the animals were recuperated 15 days after surgical procedure. Overal, most DD lesions were papillomatous epidermal projections or wartlike verrucous lesions. Histopathologically, samples revealed hyperplasia of epidermis with hyperkeratosis, several mitoses in the stratum basale and elongated rete ridges in the superficial and middle dermis. TEM revealed long, thin spirochete-like bacteria. Morphologic features of lesions and its response to therapy were comparable to those described for DD.

  10. Behaviour of bentonite accessory minerals during the thermal stage

    Arcos, David; Bruno, Jordi [Enviros-QuantiSci, Barcelona (Spain); Benbow, Steven; Takase, Hiro [Quintessa Limited, Henley-on-Thames (United Kingdom)

    2000-03-15

    This report discusses in a quantitative manner the evolution of the accessory minerals in the bentonite as a result of the thermal event exerted by the spent fuel in the near field. Three different modelling approaches have been used and the results compared between them. The three different approaches have been calculated using two Differential Algebraic Equation (DAE) solver: DYLAN (Model-1) and the Nag DAE solver, d02ngf (Model-2) and the third approach (Model-3) using the last version of PHREEQC. The results from these calculations indicate the feasibility of the modelling approach to model the migration of bentonite accessory minerals and relevant aqueous species throughout the thermal gradient. These calculations indicate that the migration of quartz and quartz polymorphs is a lesser problem. The aqueous speciation of Ca in the bentonite pore water is fundamental in order to define the potential migration of anhydrite during the thermal stage. If CaSO{sub 4}(aq) is the predominant aqueous species, then anhydrite dissolves at the initial groundwater migration times through bentonite. However, if Ca{sup 2+} is considered to be the dominant Ca species at the bentonite pore water, then anhydrite migrates towards the clay/granite interface. This is the main difference in the chemical systems considered in the three model approaches used in this work. The main process affecting the trace mineral behaviour in bentonite is cation exchange. This process controls the concentration of calcium, which results in a direct control of the calcite precipitation-dissolution.

  11. Nipple adenoma arising from axillary accessory breast: a case report

    Shioi Yoshihiro

    2012-11-01

    Full Text Available Abstract Nipple adenoma is a relatively rare benign breast neoplasm, and cases of the disease arising from the axillary accessory breast have very seldom been reported in the English literature. We report a case of nipple adenoma arising from axillary accessory breast including clinical and pathological findings. An 82-year-old woman presented with the complaint of a small painful mass in the right axilla. Physical examination confirmed a well-defined eczematous crusted mass that was 8 mm in size. The diagnosis of nipple adenoma was made from an excisional specimen on the basis of characteristic histological findings. Microscopic structural features included a compact proliferation of small tubules lined by epithelial and myoepithelial cells, and the merging of glandular epithelial cells of the adenoma into squamous epithelial cells in the superficial epidermal layer. Because clinically nipple adenoma may resemble Paget’s disease and pathologically can be misinterpreted as tubular carcinoma, the correct identification of nipple adenoma is an important factor in the differential diagnosis for axillary tumor neoplasms.

    2016-08-01

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

  6. Effect of Electroacupuncture on the Expression of Glycyl-tRNA Synthetase and Ultrastructure Changes in Atrophied Rat Peroneus Longus Muscle Induced by Sciatic Nerve Injection Injury

    Meng Wang

    2016-01-01

    Full Text Available Glycyl-tRNA synthetase (GlyRS is one of the key enzymes involved in protein synthesis. Its mutations have been reported to cause Charcot-Marie-Tooth disease which demonstrates muscular atrophy in distal extremities, particularly manifested in peroneus muscles. In this situation, the dysfunctions of mitochondria and sarcoplasmic reticulum (SR affect energy supply and excitation-contraction coupling of muscle fibers, therefore resulting in muscular atrophy. Although the treatment of muscular atrophy is a global urgent problem, it can be improved by electroacupuncture (EA treatment. To investigate the mechanism underlying EA treatment improving muscular atrophy, we focused on the perspective of protein synthesis by establishing a penicillin injection-induced sciatic nerve injury model. In our model, injured rats without treatment showed decreased sciatic functional index (SFI, decreased peroneus longus muscle weight and muscle fiber cross-sectional area, aggregated mitochondria with vacuoles appearing, swollen SR, and downregulated mRNA and protein expression levels of GlyRS and myosin heavy chain IIb (MHC-IIb. The injured rats with EA treatment showed significant recovery. These results indicated that EA stimulation can alleviate peroneus longus muscular atrophy induced by iatrogenic sciatic nerve injury through promoting the recovery of GlyRS and muscle ultrastructure and increasing muscle protein synthesis.

  7. Chiasma crurale: intersection of the tibialis posterior and flexor digitorum longus tendons above the ankle. Magnetic resonance imaging-anatomic correlation in cadavers

    To determine the precise anatomy and magnetic resonance (MR) imaging appearance of the chiasma crurale in cadavers, paying special attention to degenerative changes Twelve fresh human ankles were harvested from 11 nonembalmed cadavers (mean age at death 77 years) and used according to institutional guidelines. MR imaging and MR tenography were used to investigate the anatomy of the chiasma crurale using proton density-weighted sequences. The gross anatomy of the chiasma crurale was evaluated and compared to the MR imaging findings. Histology was used to elucidate further the structure of the chiasma crurale. Above the chiasma, five specimens had a small amount of fat tissue between the tibialis posterior and flexor digitorum longus tendon. In all specimens both tendons had a sheath below the chiasma but not above it. At the central portion of the chiasma there was no soft tissue between the tendons, except in two specimens that showed an anatomic variant consisting of a thick septum connecting the tibial periosteum and the deep transverse fascia of the leg. In MR images, eight specimens showed what were believed to be degenerative changes in the tendons at the level of the chiasma. However, during gross inspection and histologic analysis of the specimens, there was no tendon degeneration visible. At the central portion of the chiasma, there is no tissue between the tibialis posterior and flexor digitorum longus tendons unless there is an anatomic variant. At the chiasma crurale, areas with irregular tendon surfaces are normal findings and are not associated with tendon degeneration (fraying). (orig.)

  8. Technical tip: Side-to-side tendon suture as escape plan during extensor indicis tendon plasty in distal extensor pollicis longus rupture

    Schleh, Andrea Christina

    2015-11-01

    Full Text Available Objective: In case of a short distal recipient stump after extensor pollicis longus (EPL tendon rupture, transfer of the extensor indicis proprius (EIP tendon using a conventional Pulvertaft tendon-weaving technique may be difficult or impossible. The purpose of this paper is to provide a technical tip to manage this rare, but clinically important scenario of a very short distal EPL recipient tendon.Methods: A side-to-side tendon suture (SSTS was used for EIP transfer to restore thumb extension in 3 patients who had sustained a distal rupture of their extensor pollicis longus near the interphalangeal joint. The SSTS was performed with an overlap of 2 cm in 2 patients and in one patient.Results: A stable SSTS was achieved which allowed early active mobilization and resulted in good functional recovery of thumb extension after a mean follow-up of 8 months.Conclusion: Extensor indicis transfer using SSTS is a reliable and technically simple escape plan in a distal rupture of the EPL near the phalangeal joint. It provides very stable tendon-to-tendon attachment with high loading capacity and good gliding qualities.

  10. Role of nuclear medicine imaging in differential diagnosis of accessory spleens in patients after splenectomy

    More than 10% of healthy population has one or more accessory spleens. The most common location is the hilum of the spleen or area near the tail of the pancreas. The radiological appearance of accessory spleens in oncologic patients who underwent splenectomy can be misinterpreted as a recurrence, especially in the case of compensatory growth of an accessory spleen in successive radiological examinations. We present the cases of three patients who underwent splenectomy for gastric carcinoid, gastric adenocarcinoma and cancer of the left adrenal gland, respectively. CT examination and/or PET-CT scan revealed suspicious findings in the left upper abdomen. In one patient, the dimensional increase of this finding in successive examinations was initially considered suggestive for cancer recurrence. Scintigraphy with 99mTc-nanocolloid was able to confirm the presence of an accessory spleen in all these patients. Splenic scintigraphy is an economical, accessible and accurate tool in differential diagnosis of accessory spleens in patients after splenectomy

  11. Fast Image Retrieval of Textile Industrial Accessory Based on Multi-Feature Fusion

    沈文忠; 杨杰

    2004-01-01

    A hierarchical retrieval scheme of the accessory image database is proposed based on textile industrial accessory contour feature and region feature. At first smallest enclosed rectangle[1] feature (degree of accessory coordination) is used to filter the image database to decouple the image search scope. After the accessory contour information and region information are extracted, the fusion multi-feature of the centroid distance Fourier descriptor and distance distribution histogram is adopted to finish image retrieval accurately. All the features above are invariable under translation, scaling and rotation. Results from the test on the image database including 1,000 accessory images demonstrate that the method is effective and practical with high accuracy and fast speed.

    Objective: The purpose of our study was to demonstrate that ultrasonography may allow a precise assessment of the course and relationships of the spinal accessory nerve (SAN). Material and methods: This study, initially undertaken in 7 cadavers, was followed by high-resolution ultrasonographic study in 15 volunteers (30 nerves) by two radiologists in consensus. The location, course and relations to the adjacent anatomic structures of the SAN were analyzed. Results: The precise course of the SAN between the lateroposterior border of the sternocleidomastoid muscle and the anterior border of the trapezius muscle could be identified by high-resolution ultrasonography. In contrast, clinical bone landmarks were not found helpful for the identification of the nerve. Conclusion: The SAN can be clearly depicted by means of ultrasonography. Knowledge of the nerve's precise location, which may evidence individual variations, may have useful clinical applications.

    2016-03-01

    This paper describes an investigation of the sudden and unexpected death of a five-and-a-half-month-old boy. As in every Dutch case of sudden unexpected death in infancy (SUDI), a multidisciplinary diagnostic approach was used. This included post-mortem radiography, showing a linear discontinuity of the parietal bone. Originally this was interpreted as a skull fracture, but autopsy indicated no signs of mechanical trauma. Instead the defect was defined as a unilateral accessory suture of the parietal bone. The initial erroneous diagnosis had severe adverse consequences and thus every health care professional or forensic specialist dealing with paediatric mechanical traumas should be cautious of this rare anomaly.

  17. Accessory liver lobe of the gallbladder in adults.

    Handra-Luca, Adriana

    2016-09-01

    The accessory liver lobe (ALL) of the gallbladder wall is rare, mentioned by Meckel since 1822. We present two cases of ALL occurring in two adult women. The ALLs were diagnosed at microscopic examination of cholecystectomy specimens for lithiasic cholecystitis and were located at the gallbladder body level. They measured 0.5 and 1.1 cm and were pediculated from the gallbladder serosa. Luschka duct complexes were seen in the adjacent subserosa in one of the cases. The main clinical relevance of ALL of the gallbladder resides in the differential diagnosis with a lymph node and in the risk of peroperative hemorragia or bile leakage by sectioning of the connecting blood vessels and/or bile duct. Intraparietal ALL may interfere with dysmotility, possibly resulting in bile stagnation and stone formation. PMID:27147442

  18. New Scopes, New Accessories, New Stents for Interventional Endoscopic Ultrasound.

    Chapman, Christopher G; Siddiqui, Uzma D

    2016-01-01

    Technological advances have rapidly expanded the therapeutic potential of endoscopic ultrasound (EUS). Innovations in stent technology; directed adjunctive therapy for pancreatic tumors, including radiofrequency ablation and fiducial marker placement; advanced imaging modalities, including needle-based confocal laser endomicroscopy; and new echoendoscopes, such as the forward-viewing linear echoendoscope, are emerging as safe and effective tools and devices for providing a broad range of treatments and therapies previously not thought possible. In this review, we summarize and discuss the new echoendoscopes, accessories, and stents for interventional EUS and highlight the recent literature on technical and therapeutic efficacy. The therapeutic role and indications for EUS are rapidly evolving well beyond its current limits as new EUS-specific designed tools are designed, and ultimately, should help achieve the goal of improving patient outcomes.

    Full Text Available Registramos pelo presente estudo que o músculo (ELP e seu tendão apresentaram poucas variações anatômicas. Não registramos a presença de tendões acessórios e nem a ausência desse músculo ou de seu tendão. Verificamos em todas as preparações a passagem do tendão pelo terceiro compartimento osteofibroso, cruzando sobre os extensor radial curto (ERCC e longo (ERLC do carpo e dirigindo-se ao polegar. A alteração no trajeto tendinoso, desviando-se no sentido radial foi verificada em uma das preparações (1,6%. A duplicação parcial do tendão proximal a articulação metacarpofalângica (AMFP foi verificada em 3 observações (4,8%, sendo 1 bilateral, e distal à articulação em 5 (8,3%, 2 bilateralmente. A inserção óssea na base da falange distal (BFD foi encontrada em todas as observações. Durante sua passagem pela articulação metacarpofalângica, registramos sua inserção na cápsula articular em 14 observações (23,3%, porém não registramos a inserção óssea nesse local. O padrão mais comum em relação ao músculo ELP foi a presença constante de 1 tendão, passando pelo terceiro compartimento osteofibroso dorsal do punho com inserção óssea na base da falange distal do polegar.We recorded with this study that the EPL muscle and its tendon show a few anatomical variations.

  20. Dynamic computed tomography findings of an accessory spleen in the pelvis: a case report.

    Ota, Hiroshi; Ojima, Yasutomo; Sumitani, Daisuke; Okajima, Masazumi

    2016-12-01

    We report the case of a 60-year-old man with an accessory spleen in the pelvis. He visited our outpatient clinic because of abdominal discomfort. Computed tomography (CT) showed an enhanced mass (40 mm in diameter) in the pelvis. Preoperative diagnosis was difficult even after magnetic resonance imaging and colonoscopy. The patient underwent surgery for suspicion of a gastrointestinal stromal tumor or malignant lymphoma of the rectum. Intraoperative findings showed a mass in the pelvis and a long cord-like tissue reaching the mass and arising from the great omentum; the mass was excised. Histopathologic examination indicated that the mass was splenic tissue, and feeding vessels were found in the cord-like tissue, which were determined to be derived from the left gastroepiploic artery and vein. Thus, we diagnosed it as an accessory spleen in the pelvis. An accessory spleen is not rare and can occur anywhere in the abdominal cavity. However, an accessory spleen in the pelvis is an infrequent finding, and only 9 other cases of an accessory spleen in the pelvis have been reported. Therefore, it is very difficult to make a correct diagnosis preoperatively. However, 7 of the 9 cases (77.8 %) of a pelvic accessory spleen had vascular pedicles from the great omentum or splenic hilum as feeding vessels; hence, determining the feeding blood vessels on dynamic CT may be useful for diagnosing an accessory spleen in the pelvis. Additionally, if the accessory spleen is symptomatic or has a vascular pedicle, surgeons should attempt to resect the accessory spleen in the pelvis using minimally invasive laparoscopy.

  1. Deleterious effect of ultraviolet-B radiation on accessory function of human blood adherent mononuclear cells

    The effects of ultraviolet-B radiation (UV-B) on accessory function of human blood adherent mononuclear cells (ADH) for antigen and mitogen-induced responses, and production by ADH of the amplifying cytokine interleukin 1 (IL-1) were examined. Responder lymphocytes were rendered accessory cell dependent by treatment of nonadherent cells with OKIal + complement. UV-B depressed accessory function of ADH in a dose-dependent manner. UV-B decreased accessory function of ADH for tetanus toxoid-induced responses and phytohaemagglutinin-induced responses. UV-B also decreased accessory activity of peripheral blood mononuclear cells but not Epstein-Barr virus-transformed B cells for a PPD-reactive T cell line. Interleukin 1 (IL-1) activity of supernatants of ADH was assayed on C3H/HeJ mouse thymocytes. Pretreatment of ADH with UV-B decreased lipopolysaccharide-stimulated IL-1 activity. Lysates of UV-B irradiated, LPS-stimulated ADH had no discernible IL-1 activity. Addition of IL-1 partially restored accessory activity of UV-B irradiated ADH for lymphocyte responses to TT. Exposure of ADH to TT or PHA for 30 min before irradiation blocked the inhibitory effect of UV-B on accessory activity. Thus, low doses of UV-B are deleterious to accessory function and to production of IL-1 by ADH. Interference with production of cytokines and with initial interactions of accessory cells with antigen and mitogen may be critical to the effects of UV-B on immunoregulatory function of ADH.

    Primary accessory breast cancer is extremely rare, and the diagnostic efficacy of Tc-MIBI breast-specific γ imaging (BSGI) has not been reported elsewhere. We present a case of primary carcinoma arising from dense accessory breast that was visualized with BSGI. A 43-year-old female patient with a palpable axillary mass underwent mammography, which showed dense parenchyma on both of the anatomic and accessory breasts with no abnormality. Subsequent BSGI showed no abnormal uptake in bilateral anatomic breasts, but focal abnormal uptake was noted in the accessory breast. Permanent pathologic evaluation confirmed invasive ductal carcinoma (not otherwise specified type) of the accessory breast. PMID:24445272

  4. EMG and force production of the flexor hallucis longus muscle in isometric plantarflexion and the push-off phase of walking.

    Péter, Annamária; Hegyi, András; Stenroth, Lauri; Finni, Taija; Cronin, Neil J

    2015-09-18

    Large forces are generated under the big toe in the push-off phase of walking. The largest flexor muscle of the big toe is the flexor hallucis longus (FHL), which likely contributes substantially to these forces. This study examined FHL function at different levels of isometric plantarflexion torque and in the push-off phase at different speeds of walking. FHL and calf muscle activity were measured with surface EMG and plantar pressure was recorded with pressure insoles. FHL activity was compared to the activity of the calf muscles. Force and impulse values were calculated under the big toe, and were compared to the entire pressed area of the insole to determine the relative contribution of big toe flexion forces to the ground reaction force. FHL activity increased with increasing plantarflexion torque level (F=2.8, P=0.024) and with increasing walking speed (F=11.608, Pcalf muscles, highlighting the task-dependant behaviour of FHL.

  5. Chronic Posttraumatic Dislocation of Radial Head With Ulnar Nerve Entrapment in a Child: A Case Report and Literature Review.

    Cai, Jiangyu; Wang, Wei; Yu, Shiyang; Yan, Hede; Zhan, Yulin; Fan, Cunyi

    2016-06-01

    We present an unusual case of chronic posttraumatic anteromedial dislocation of radial head with direct ulnar nerve entrapment in a child. Ulnar nerve decompression, open reduction of the radial head, and annular ligament reconstruction using a palmaris longus tendon graft were performed, and a satisfactory functional outcome was achieved at the 15-month follow-up. Through a review of literature, we conclude that early diagnosis and management for radial head dislocation are recommended to avoid nerve symptoms. Besides, open reduction and annular ligament reconstruction with a palmaris longus tendon graft would be an alternative surgery during chronic phase. PMID:27171922

  6. Musculoskeletal Management of a Patient With a History of Chronic Ankle Sprains: Identifying Rupture of Peroneal Brevis and Peroneal Longus With Diagnostic Ultrasonography

    Bruin, Dick B.; von Piekartz, Harry

    2014-01-01

    Objective The purpose of this case report is to describe the use of mobilization and eccentric exercise training for a patient with ankle pain and a history of chronic ankle sprains and discuss the course of diagnostic decision making when the patient did not respond to care. Clinical Features A 48-year-old police officer who had sustained multiple ankle sprains throughout his life presented with pain and restriction in his ability to walk, run, and work. The Global Rating of Change Scale score was − 6, the Numeric Pain Rating Scale score was 7/10, and the Lower Extremity Functional Scale score was − 33. Palpation of the peroneus longus and brevis muscles and inversion with overpressure reproduced the chief concern (Numeric Pain Rating Scale 7/10). The patient was initially diagnosed with chronic peroneal tendinopathy. Intervention and Outcome Treatment included lateral translation mobilization of the talocrural joint combined with eccentric exercise using an elastic band for the peroneal muscles. The patient reported improvement in pain and function during the course of intervention but not as rapidly as expected. Therefore, follow-up ultrasonographic imaging and radiography were performed. These studies revealed partial rupture of the peroneal brevis muscle and total rupture of the peroneal longus muscle. Conclusion A patient with long-term concerns of the foot complex with a diagnosis of peroneal tendinopathy showed slight improvement with eccentric exercises combined with manual therapy of the talocrural joint. After a course of treatment but minimal response, a diagnosis of tendon rupture was confirmed with diagnostic ultrasonography. Clinicians should be aware that when injuries do not improve with care, tendon rupture should be considered. PMID:25225470

  7. One nose, one brain: contribution of the main and accessory olfactory system to chemosensation

    Carla eMucignat

    2012-11-01

    Full Text Available The accessory olfactory system is present in most tetrapods. It is involved in the perception of chemical stimuli, being implicated also in the detection of pheromone. However, it is sensitive also to some common odorant molecules, which have no clear implication in intraspecific chemical communication. The accessory olfactory system may complement the main olfactory system, and may contribute different perceptual features to the construction of a unitary representation, which merges the different chemosensory qualities. Crosstalk between the main and accessory olfactory systems occurs at different levels of central processing, in brain areas where the inputs from the two systems converge. Interestingly, centrifugal projections from more caudal brain areas are deeply involved in modulating both main and accessory sensory processing. A high degree of interaction between the two systems may be conceived, and partial overlapping appears to occur in many functions. Therefore, the central chemosensory projections merge inputs from different organs to obtain a complex chemosensory picture.

    2011-01-01

    In this paper, we develop a cellular automaton model to describe the phase transition of traffic flow on urban expressway systems with on-off-ramps and accessory roads. The lane changing rules are given in detailed, the numerical results show that the main road and the accessory road both produce phase transitions. These phase transitions will omen be influenced by the number of lanes, lane changing, the ramp flow, the input flow rate, and the geometry structure.

    Melanocortin receptor accessory proteins (MRAPs) modulate signaling of melanocortin receptors in vitro. To investigate the physiological role of brain-expressed Melanocortin 2 Receptor Accessory Protein 2 (MRAP2), we characterized mice with whole body and brain-specific targeted deletion of Mrap2, both of which develop severe obesity at a young age. Mrap2 interacts directly with Melanocortin 4 Receptor (Mc4r), a protein previously implicated in mammalian obesity, and it enhances Mc4r-mediated...

  13. Activity Regulates Functional Connectivity from the Vomeronasal Organ to the Accessory Olfactory Bulb

    Hovis, Kenneth R.; Ramnath, Rohit; Dahlen, Jeffrey E.; Romanova, Anna L.; LaRocca, Greg; Bier, Mark E.; Urban, Nathaniel N.

    2012-01-01

    The mammalian accessory olfactory system is specialized for the detection of chemicals that identify kin and conspecifics. Vomeronasal sensory neurons (VSNs), residing in the vomeronasal organ, project axons to the accessory olfactory bulb (AOB) where they form synapses with principle neurons, known as mitral cells. The organization of this projection is quite precise and is believed to be essential for appropriate function of this system. However, how this precise connectivity is established...

  14. One nose, one brain: contribution of the main and accessory olfactory system to chemosensation

    Mucignat-Caretta, Carla; Redaelli, Marco; Caretta, Antonio

    2012-01-01

    The accessory olfactory system is present in most tetrapods. It is involved in the perception of chemical stimuli, being implicated also in the detection of pheromones. However, it is sensitive also to some common odorant molecules, which have no clear implication in intraspecific chemical communication. The accessory olfactory system may complement the main olfactory system and may contribute different perceptual features to the construction of a unitary representation, which merges the diff...

  17. Dynamic expression pattern of kinesin accessory protein in Drosophila

    Ritu Sarpal; Krishanu Ray

    2002-09-01

    We have identified the Drosophila homologue of the non-motor accessory subunit of kinesin-II motor complex. It is homologous to the SpKAP115 of the sea urchin, KAP3A and KAP3B of the mouse, and SMAP protein in humans. In situ hybridization using a DmKAP specific cRNA probe has revealed a dynamic pattern of expression in the developing nervous system. The staining first appears in a subset of cells in the embryonic central nervous system at stage 13 and continues till the first instar larva stage. At the third instar larva stage the staining gets restricted to a few cells in the optic lobe and in the ventral ganglion region. It has also stained a subset of sensory neurons from late stage 13 and till the first instar larva stage. The DmKAP expression pattern in the nervous system corresponds well with that of Klp64D and Klp68D as reported earlier. In addition, we have found that the DmKAP gene is constitutively expressed in the germline cells and in follicle cells during oogenesis. These cells are also stained using an antibody to KLP68D protein, but mRNA in situ hybridization using KLP64D specific probe has not stained these cells. Together these results proved a basis for further analysis of tissue specific function of DmKAP in future.

  18. Cummins MD & HD Accessory Hybridization CRADA -Annual Report FY15

    Deter, Dean D. [Oak Ridge National Lab. (ORNL), Oak Ridge, TN (United States)

    2015-10-01

    There are many areas of MD and HD vehicles that can be improved by new technologies and optimized control strategies. Component optimization and idle reduction need to be addressed, this is best done by a two part approach that includes selecting the best component technology, and/or architecture, and optimized controls that are vehicle focused. While this is a common focus in the light duty industry it has been gaining momentum in the MD and HD market as the market gets more competitive and the regulations become more stringent. When looking into systems optimization and idle reduction technologies, affected vehicle systems must first be considered, and if possible included in the new architecture to get the most benefit out of these new capabilities. Typically, when looking into idle reduction or component optimization for MD/HD, the vehicle s accessories become a prime candidate for electrification or hybridization. While this has already been studied on light duty vehicles (especially on hybrids and electric vehicles) it has not made any head way or market penetration in most MD and HD applications. If hybrids and electric MD and HD vehicles begin to break into the market this would be a necessary step into the ability to make those vehicles successful by allowing for independent, optimized operation separate from the engine.

  19. Rock sealing - large scale field test and accessory investigations

    The experience from the pilot field test and the basic knowledge extracted from the lab experiments have formed the basis of the planning of a Large Scale Field Test. The intention is to find out how the 'instrument of rock sealing' can be applied to a number of practical cases, where cutting-off and redirection of groundwater flow in repositories are called for. Five field subtests, which are integrated mutually or with other Stripa projects (3D), are proposed. One of them concerns 'near-field' sealing, i.e. sealing of tunnel floors hosting deposition holes, while two involve sealing of 'disturbed' rock around tunnels. The fourth concerns sealing of a natural fracture zone in the 3D area, and this latter test has the expected spin-off effect of obtaining additional information on the general flow pattern around the northeastern wing of the 3D cross. The fifth test is an option of sealing structures in the Validation Drift. The longevity of major grout types is focussed on as the most important part of the 'Accessory Investigations', and detailed plans have been worked out for that purpose. It is foreseen that the continuation of the project, as outlined in this report, will yield suitable methods and grouts for effective and long-lasting sealing of rock for use at stategic points in repositories.

  20. Accessory soleus muscle: a case report and clinical applicability

    William Paganini Mayer

    2013-10-01

    Full Text Available Variations in leg muscle are uncommon. Literature on this subject is scarce, but when those variations are reported they may cause alterations in joint mechanics or cause some discomfort in the leg and foot. The accessory soleus muscle (ASM is considered an unusual anatomical variation, with an  incidence of 0.5-6.0% in the population through studies in cadavers. During routine preparation of study material in the dissection room of the anatomy laboratory of the Escola Superior de Ciências da Santa Casa de Misericórdia de Vitória/ES – Brazil, an ASM was found in the right inferior limb of a male cadaver fixed in 10% formalin. This supernumerary muscle was 3 cm wide, 9 cm long and 1 cm thick in its most voluminous part, in typical penniform fibers arrangement. It was located in the posteromedial region of the ankle, anterior to the Achilles tendon and posterior to the deep muscles of the leg compartment. Its anterior face covered the tibial nerve and the posterior tibial vessels, while its lower half was covered by the flexor retinaculum into the tarsal tunnel. Reports in the literature show possible compression of a neurovascular bundle because of its intimal position within the tarsal tunnel, which could result in ischemic compartment syndrome.

    To evaluate the MR imaging findings of painful type II accessory navicular bone and to correlate these with the surgical and pathologic findings. The MR images of 17 patients with medial foot pain and surgically proven type II accessory navicular abnormalities were reviewed. The changes of signal intensity in the accessory navicular, synchondrosis and adjacent soft tissue, the presence of synchondrosis widening, and posterior tibial tendon (PTT) pathology on the T1-weighted and fat-suppressed T2-weighted images were analyzed. The MR imaging findings were compared with the surgical and pathologic findings. The fat-suppressed T2-weighted images showed high signal intensity in the accessory navicular bones and synchondroses in all patients, and in the soft tissue in 11 (64.7%) of the 17 patients, as well as synchondrosis widening in 3 (17.6%) of the 17 patients. The MR images showed tendon pathology in 12 (75%) of the 16 patients with PTT dysfunction at surgery. The pathologic findings of 16 surgical specimens included areas of osteonecrosis with granulomatous inflammation, fibrosis and destruction of the cartilage cap. The MR imaging findings of painful type II accessory navicular bone are a persistent edema pattern in the accessory navicular bone and within the synchondrosis, indicating osteonecrosis, inflammation and destruction of the cartilage cap. Posterior tibial tendon dysfunction was clinically evident in most patients.

  4. Infrahyoid and accessory motoneurons in the Japanese monkey (Macaca fuscata).

    Ueyama, T; Satoda, T; Tashiro, T; Sugimoto, T; Matsushima, R; Mizuno, N

    1990-01-15

    The segmental and topographical organization of motoneurons innervating the infrahyoid (IH) and the spinal accessory (AC) muscles was studied in the Japanese monkey (Macaca fuscata) with the retrograde horseradish peroxidase (HRP) method after application of HRP to the peripheral nerve branches supplying the IH and AC muscles. IH motoneurons constitute two distinct slender cell columns, a longer medial and a shorter lateral one. The medial cell column extends from the most caudal level of the hypoglossal nucleus to the lower levels of the second cervical (C2) cord segment. In the medial column, motoneurons supplying the sternohyoid and sternothyroid muscles are distributed at the medullary and C1 levels, while those innervating the omohyoid muscle are primarily distributed at the C2 level. The lateral cell column consists of motoneurons supplying the thyrohyoid muscle and extends from the most caudal level of the hypoglossal nucleus to the middle levels of the C1 cord segment. Axons of thyrohyoid motoneurons follow a dorsomedially directed bent emergent course, making a hairpin turn. AC motoneurons supplying the sternocleidomastoid (SC) and trapezius (TZ) muscles form a single slender cell column extending from the most rostral level of the pyramidal decussation to the middle levels of the C6 cord segment. SC motoneurons are distributed from the most rostral level of the pyramidal decussation to the middle levels of the C3 cord segment, while TZ motoneurons are distributed from the upper levels of the C2 cord segment to the lower levels of the C6 cord segment. At the levels of the C2 and C3 cord segments, both SC and TZ motoneurons are distributed in the AC cell column; the cluster of SC motoneurons is located dorsomedial to that of TZ motoneurons.

    This anatomical study examines the anatomic topography and landmarks for localization of the spinal accessory nerve (SAN) during surgical dissections in 40 fresh human cadavers (2 females and 38 males; ages from 22 to 89 years with a mean of 60 years). In the submandibular region, the SAN was found anteriorly to the transverse process of the atlas in 77.5% of the dissections. When the SAN crossed the posterior belly of the digastric muscle, the mean distance from the point of crossing to the tendon of the muscle was 1.75 +/- 0.54 cm. Distally, the SAN crossed between the two heads of the SCM muscle in 45% of the dissections and deep to the muscle in 55%. The SAN exited the posterior border of the sternocleidomastoid muscle in a point superior to the nerve point with a mean distance between these two anatomic parameters of 0.97 +/- 0.46 cm. The mean overall extracranial length of the SAN was 12.02 +/- 2.32 cm, whereas the mean length of the SAN in the posterior triangle was 5.27 +/- 1.52 cm. There were 2-10 lymph nodes in the SAN chain. In conclusion, the nerve point is one of the most reliable anatomic landmarks for localization of the SAN in surgical neck dissections. Although other anatomic parameters including the transverse process of the atlas and the digastric muscle can also be used to localize the SAN, the surgeon should be aware of the possibility of anatomic variations of those parameters. Similar to previous investigations, our results suggest that the number of lymph nodes of the SAN chain greatly varies. PMID:19373901

    2016-01-01

    Permanent junctional reciprocating tachycardia (PJRT) is an uncommon form of atrioventricular reentrant tachycardia due to an accessory pathway characterized by slow and decremental retrograde conduction. The majority of accessory pathways in PJRT are located in the posteroseptal zone. Few cases of atypical location have been described. We report a case of PJRT in a 72-year-old woman in whom the accessory pathway was located in the left lateral region and treated by radiofrequency catheter ablation. PMID:26749575

    Retrograde transport of the fluorescent tracers Diamidino Yellow dihydrochloride and Fast Blue was used to determine the location of the spinal nucleus of the accessory nerve in the sheep. We also considered whether in this species the sternocephalic, brachiocephalic, omotransversarius and trapezius muscles, i.e. the muscles of the spinal accessory complex, are supplied by more than one population of motoneurons. The spinal accessory nucleus extends as a single column of neurons from C1 to C7...

  9. Localization of an accessory helicase at the replisome is critical in sustaining efficient genome duplication.

    Atkinson, John; Gupta, Milind K; Rudolph, Christian J; Bell, Hazel; Lloyd, Robert G; McGlynn, Peter

    2011-02-01

    Genome duplication requires accessory helicases to displace proteins ahead of advancing replication forks. Escherichia coli contains three helicases, Rep, UvrD and DinG, that might promote replication of protein-bound DNA. One of these helicases, Rep, also interacts with the replicative helicase DnaB. We demonstrate that Rep is the only putative accessory helicase whose absence results in an increased chromosome duplication time. We show also that the interaction between Rep and DnaB is required for Rep to maintain rapid genome duplication. Furthermore, this Rep-DnaB interaction is critical in minimizing the need for both recombinational processing of blocked replication forks and replisome reassembly, indicating that colocalization of Rep and DnaB minimizes stalling and subsequent inactivation of replication forks. These data indicate that E. coli contains only one helicase that acts as an accessory motor at the fork in wild-type cells, that such an activity is critical for the maintenance of rapid genome duplication and that colocalization with the replisome is crucial for this function. Given that the only other characterized accessory motor, Saccharomyces cerevisiae Rrm3p, associates physically with the replisome, our demonstration of the functional importance of such an association indicates that colocalization may be a conserved feature of accessory replicative motors.

    2012-01-01

    Carcinoma of an accessory mammary gland is an extremely rare tumor. A 61-year-old male patient presented with a hard mass measuring 85 mm × 51 mm in the left axilla. Incisional biopsy histopathologically showed an adenocarcinoma compatible with breast carcinoma originating in an accessory mammary gland. Systemic examinations revealed no evidence of malignant or occult primary lesion in the bilateral mammary glands or in other organs. Neoadjuvant chemotherapy was performed for the locally advanced axillary tumor and reduced the tumor to 55 mm in size, and, then, he could undergo complete resection with a negative surgical margin in combination with reconstructive surgery to fill the resulting skin defect with a local flap of the latissimus dorsi muscle. The patient has presented with no metastatic lesion in four years since the operation. This unusual case shows that neoadjuvant chemotherapy is an effective and tolerated therapy for advanced accessory breast cancer in the axilla. PMID:23251170

    Full Text Available Nipple adenoma is a relatively rare benign breast neoplasm, and cases of the disease arising from the Accessory breast nipple are a rare entity. We report a case of nipple adenoma arising from accessory nipple. A 24 - year - old woman presented with the complaint of pain and bleeding from accessory nipple since 4 months in right breast. Physical examination confirmed a well - defined nipp le in the milk line 5 cm below right nipple. The diagnosis of nipple adenoma was made from an excisional specimen on the basis of characteristic histological findings. Because clinically nipple adenoma may resemble Paget’s disease and pathologically can be misinterpreted as tubular carcinoma, the correct identification of nipple adenoma is an important factor in the differential diagnosis for nipple neoplasms

  13. iNOS ablation does not improve specific force of the extensor digitorum longus muscle in dystrophin-deficient mdx4cv mice.

    Dejia Li

    Full Text Available Nitrosative stress compromises force generation in Duchenne muscular dystrophy (DMD. Both inducible nitric oxide synthase (iNOS and delocalized neuronal NOS (nNOS have been implicated. We recently demonstrated that genetic elimination of nNOS significantly enhanced specific muscle forces of the extensor digitorum longus (EDL muscle of dystrophin-null mdx4cv mice (Li D et al J. Path. 223:88-98, 2011. To determine the contribution of iNOS, we generated iNOS deficient mdx4cv mice. Genetic elimination of iNOS did not alter muscle histopathology. Further, the EDL muscle of iNOS/dystrophin DKO mice yielded specific twitch and tetanic forces similar to those of mdx4cv mice. Additional studies suggest iNOS ablation did not augment nNOS expression neither did it result in appreciable change of nitrosative stress markers in muscle. Our results suggest that iNOS may play a minor role in mediating nitrosative stress-associated force reduction in DMD.

    2015-12-01

    Stenosing tenosynovitis of the flexor hallucis longus (FHL) tendon is known as a major overuse lesion in female dancers. We describe arthroscopic surgical techniques in relation to the dynamic pathology of the disease. Crepitus and pain on moving the great toe with the ankle in plantar flexion on preoperative examination confirm the diagnosis of FHL stenosing tenosynovitis even if the os trigonum is not evident. The ankle is approached through standard posterolateral and posteromedial portals. A 4.0-mm-diameter 30° arthroscope is used. Soft tissues around the talus are cleared with a motorized shaver and a radiofrequency device. The posterior aspects of the talus, os trigonum, and FHL tendon surrounded by the tendon sheath are visualized. The dynamic pathology of the FHL tendon is well observed on passive motion of the great toe. The prominent bone fragment of the talus is removed and the tendon sheath is cut with a retrograde knife and a motorized shaver from the superior border down to the entrance of the fibro-osseous tunnel. Arthroscopic release of the FHL tendon sheath is a useful and easy method to directly approach the dynamic pathology of FHL tenosynovitis in female ballet dancers. PMID:27284509

  15. Relative contribution of expectancy and immediate arousal to the facilitatory effect of an auditory accessory stimulus

    F. Del-Fava

    2004-08-01

    Full Text Available An auditory stimulus speeds up a digital response to a subsequent visual stimulus. This facilitatory effect has been related to the expectancy and the immediate arousal that would be caused by the accessory stimulus. The present study examined the relative contribution of these two influences. In a first and a third experiment a simple reaction time task was used. In a second and fourth experiment a go/no-go reaction time task was used. In each of these experiments, the accessory stimulus preceded the target stimulus by 200 ms for one group of male and female volunteers (G Fix. For another group of similar volunteers (G Var the accessory stimulus preceded the target stimulus by 200 ms in 25% of the trials, by 1000 ms in 25% of the trials and was not followed by the target stimulus in 50% of the trials (Experiments 1a and 1b or preceded the target stimulus by 200 ms in 6% of the trials and by 1000 ms in 94% of the trials (Experiments 2a and 2b. There was a facilitatory effect of the accessory stimulus for G Fix in the four experiments. There was also a facilitatory effect of the accessory stimulus at the 200-ms stimulus onset asynchrony for G Var in Experiments 1a and 1b but not in Experiments 2a and 2b. The facilitatory effects observed were larger in the go/no-go task than in the simple task. Taken together, these results suggest that expectancy is much more important than immediate arousal for the improvement of performance caused by an accessory stimulus.

  16. Accessory left atrial diverticulae: contractile properties depicted with 64-slice cine-cardiac CT.

    Killeen, Ronan P

    2012-02-01

    To assess the contractility of accessory left atrial appendages (LAAs) using multiphasic cardiac CT. We retrospectively analyzed the presence, location, size and contractile properties of accessory LAAs using multiphasic cardiac 64-slice CT in 102 consecutive patients (63 males, 39 females, mean age 57). Multiplanar reformats were used to create image planes in axial oblique, sagittal oblique and coronal oblique planes. For all appendages with an orifice diameter >or= 10 mm, axial and sagittal diameters and appendage volumes were recorded in atrial diastole and systole. Regression analysis was performed to assess which imaging appearances best predicted accessory appendage contractility. Twenty-three (23%) patients demonstrated an accessory LAA, all identified along the anterior LA wall. Dimensions for axial oblique (AOD) and sagittal oblique (SOD) diameters and sagittal oblique length (SOL) were 6.3-19, 3.4-20 and 5-21 mm, respectively. All appendages (>or=10 mm) demonstrated significant contraction during atrial systole (greatest diameter reduction was AOD [3.8 mm, 27%]). Significant correlations were noted between AOD-contraction and AOD (R = 0.57, P < 0.05) and SOD-contraction and AOD, SOD and SOL (R = 0.6, P < 0.05). Mean diverticulum volume in atrial diastole was 468.4 +\\/- 493 mm(3) and in systole was 171.2 +\\/- 122 mm(3), indicating a mean change in volume of 297.2 +\\/- 390 mm(3), P < 0.0001. Stepwise multiple regression analysis revealed SOL to be the strongest independent predictor of appendage contractility (R(2) = 0.86, P < 0.0001) followed by SOD (R(2) = 0.91, P < 0.0001). Accessory LAAs show significant contractile properties on cardiac CT. Those accessory LAAs with a large sagittal height or depth should be evaluated for contractile properties, and if present should be examined for ectopic activity during electrophysiological studies.

  17. Imaging diagnosis of accessory and cavitated uterine mass, a rare mullerian anomaly

    Nishchint Jain

    2014-01-01

    Full Text Available Accessory and Cavitated Uterine Mass (ACUM is a rare form of developmental Mullerian anomaly seen in young females, which presents as chronic recurrent pelvic pain and severe dysmenorrhea. It is an accessory cavity lying within an otherwise normal uterus. It is lined by functional endometrium and surrounded by myometrium-like smooth muscle cells; hence, it bears striking macroscopic and microscopic resemblance to the uterus. Hysterosalpingography (HSG, Ultrasonography (USG, and Magnetic Resonance Imaging (MRI form the mainstay of diagnostic imaging. The entity is often under diagnosed; therefore, a high index of suspicion combined with HSG and MRI imaging can help in making an accurate diagnosis.

    2012-08-01

    We report a rare case of an accessory lobe of the liver in the right thoracic cavity with the past history of breast cancer. A 66-year-old woman underwent thoracotomy owing to a slowly growing suspected lung tumor identified by computed tomography. The intraoperative findings revealed an accessory lobe of the liver. If this possibility had been considered, the correct diagnosis could have been achieved using computed tomography with multi-directional scanning, so that an unnecessary operation could have been avoided.

    Ultrastructural analysis of 7 biopsies from m.palmaris longus and m.deltoideus in patients with confirmed polymyositis revealed alterationand degeneration of muscle fibers and anomalies of neuro-muscular junction (NMJ). The NMJ abnormalities and following denervation ofmuscle fibers in polymyositis start with subsynaptic damages. The occurance of regeneration features in muscle fibers at any stage is characteristic for PM.

    Transrectal ultrasound of the internal urogenital tract may be used to aid in the diagnosis of reproductive tract and urinary tract pathology in both stallions and geldings. Abnormalities of the accessory sex glands of geldings are uncommon, although prostatic masses have recently been described in adult geldings presenting with dysuria, stranguria, and/or hematuria. The purpose of this study was to describe the normal ultrasonographic features and sizes of the accessory sex glands, caudal ureters, and pelvic urethra in clinically normal geldings. Eleven healthy geldings with no history of urogenital tract pathology were evaluated by a single observer experienced in ultrasound of the stallion accessory sex glands. The ultrasonographic appearance, relative anatomic relationships and sizes of the accessory sex glands, caudal ureters, and pelvic urethra were investigated using both rectal linear array and microconvex array transducers. Summary statistics including mean, standard error, confidence intervals, and range were calculated for each structure. There were no statistically significant differences in measurements between the left and right sides of paired structures or between measurements obtained with different transducers. Fluid was present in the seminal vesicles of 7 of 9 subjects. Midline cysts of the urethra as well as bulbourethral gland and prostatic cysts were identified. The normal reference ranges defined in this study will be useful in the clinical evaluation of geldings with suspected internal urogenital tract pathology. PMID:26483314

  3. Giant accessory breast: a rare occurrence reported, with a review of the literature.

    Polymastia, or the presence of supranumerary breasts, occurs in 2-6% of the female population, the spectrum of the disorder ranging between a small mole and a fully functional ectopic breast. They are often asymptomatic but require treatment when symptomatic or if they harbour malignancy. We present a case of a 41-year-old woman with an accessory breast in the left inframammary fold, which increased in size over the decade following her first pregnancy, to reach a size almost three times that of her right breast. Preoperative fine-needle aspiration and ultrasound was suggestive of accessory breast tissue, distinct from the left breast. Intraoperatively, a 14×10×8 cm accessory breast was found in the inframammary fold, distinct from the left breast and having an accessory nipple areola complex as well. A simple mastectomy was performed with trimming and rotation of the inframammary flap. The patient was happy with the cosmetic outcome. This article also reviews the literature and covers classification of polymastia, diagnostic complexities and challenges associated with surgery. PMID:26542818

    The aim of this study was to evaluate whether the viscosity of semen in patients with male accessory gland infection is related to the extension of the inflammatory process to the various glands. To achieve this, viscosity was assessed by quantitative viscosimeter and the results were expressed in centipoise (cps). The study was conducted on 30 infertile patients with clinical evidence of male accessory gland infection and a mean age of 29.0 ± 4.0 years. Their semen viscosity was evaluated through quantitative viscometer. All patients showed an increase of viscosity evaluated according to WHO criteria, while this parameter was normal in all controls. Semen viscosity of patients with male accessory gland infection (28.6 ± 2.2 cps) was significantly (P < 0.05) higher than that in the controls (10.7 ± 0.6 cps). Significantly increasing values were observed in patients with involvement of multiple gland inflammation (prostatitis accessory gland infection. PMID:21919943

  9. Normal and accessory fissures of the lung: Evaluation with contiguous volumetric thin-section multidetector CT

    The purpose of this study was to use volumetric, 1.25 mm collimation MDCT read as softcopy and using a 2D and 3D viewer tool, to establish the frequency of normal and accessory fissures, the continuity of the fissures, whether the fissures are visible as a thin line, a hypovascular region, or both, and also to establish the interobserver agreement of readers. 150 consecutive MDCT examinations were retrospectively assessed. Interobserver agreement for each of these fissures was evaluated using the Kappa statistic. All subjects had a right and a left major fissure. 96.7% of subjects also had a right minor fissure. 40% had an accessory fissure, the most common, the left minor in 16% of subjects. Most of the three usual fissures were continuous, whereas fewer than half of accessory fissures were continuous. The majority (54-100%) of normal and accessory fissures were visualized as a thin line. There was substantial to excellent interobserver agreement on the presence or absence of fissures their continuity (k = 0.96), and fair to excellent agreement on fissure morphology (k = 0.37-1.0). The prevalence of fissures on MDCT, equivalent to autopsy studies, visualizing fissures as a thin line and high interobserver agreement is probably due to the high sensitivity of MDCT, secondary to thin-section volumetric imaging.
