During the last two decades, understanding and experience of microsurgical reconstruction have increased. This is linked to improved instruments and technical devices, as well as to the increased number of available donor sites for microvascular flap transfer. If the indication is appropriate, it is now possible to perform personalised, safe and successful microsurgical reconstructions, almost independently of the patients' age. Despite these constant developments, there is little specific literature on microsurgery related to the specific problems of the elderly patient...

BACKGROUND: Injury to distal of posterior cord of brachial plexus leads to palsy of the radial and axillary nerves. The symptoms are usually motor deficits of the deltoid muscle, triceps brachii muscle, and the extensor muscles of the wrist, thumb and fingers. Tendon transfers, nerve grafts, and nerve transfers are options of surgical treatment of proximal radial nerve palsy to restore some motor functions. Tendon transfer is painful, requires a long immobilization, and decreases donor muscle strength; nevertheless, nerve transfer produces promising outcome...

Intravascular large B-cell lymphoma (IVL) is a rare type of extranodal diffuse large B-cell lymphoma (DLBCL), which often infiltrates the central nervous system (CNS) during the clinical course. Cerebral hemorrhage in patients with CNS lymphoma at presentation is rare. Herein, we describe a case of secondary CNS lymphoma with intratumoral hemorrhage, which was suggested as IVL from autopsy findings. A 76-year-old Japanese man with a history of treatment for B-cell non-Hodgkin's lymphoma was transferred to our hospital in an ambulance for generalized convulsions...

When facial nerve axotomy (FNA) is performed on immunodeficient recombinase activating gene-2 knockout (RAG-2(-/-)) mice, there is greater facial motoneuron (FMN) death relative to wild type (WT) mice. Reconstituting RAG-2(-/-) mice with whole splenocytes rescues FMN survival after FNA, and CD4+ T cells specifically drive immune-mediated neuroprotection. Evidence suggests that immunodysregulation may contribute to motoneuron death in amyotrophic lateral sclerosis (ALS). Immunoreconstitution of RAG-2(-/-) mice with lymphocytes from the mutant superoxide dismutase (mSOD1) mouse model of ALS revealed that the mSOD1 whole splenocyte environment suppresses mSOD1 CD4+ T cell-mediated neuroprotection after FNA...

BACKGROUND: Functional recovery after peripheral nerve injury and repair is related with cortical reorganization. However, the mechanism of innervating dual targets by 1 donor nerve is largely unknown. OBJECTIVE: To investigate the cortical reorganization when the phrenic nerve simultaneously innervates the diaphragm and biceps. METHODS: Total brachial plexus (C5-T1) injury rats were repaired by phrenic nerve-musculocutaneous nerve transfer with end-to-side (n = 15) or end-to-end (n = 15) neurorrhaphy...

Intraneural ganglion cysts that occur within the common peroneal nerve are a rare cause of foot drop. The current standard of treatment for intraneural ganglion cysts involving the common peroneal nerve involves (1) cyst decompression and (2) ligation of the articular nerve branch to prevent recurrence. Nerve transfers are a time-dependent strategy for recovering ankle dorsiflexion in cases of high peroneal nerve palsy; however, this modality has not been performed for intraneural ganglion cysts involving the common peroneal nerve...

Background: Injury to the common peroneal nerve disrupts the motor control pathway to ankle dorsiflexors and evertors, as well as toe extensors, resulting in pathological gait and foot drop. Direct external compression on the fibular head is the most frequent cause of peroneal nerve impairment and has poor prognosis. Methods and Patients: Here, we report the surgical outcome of 21 patients with foot drop (9 males and 12 females) who underwent nerve transfer procedure of either the superficial peroneal nerve or the tibial nerve fascicles to the motor branch of the tibialis anterior and to the deep peroneal nerve...

Radiation may affect essential functions and behaviors such as locomotion, feeding, learning and memory. Although whole-body irradiation has been shown to reduce motility in the nematode Caenorhabditis elegans, the detailed mechanism responsible for this effect remains unknown. Targeted irradiation of the nerve ring responsible for sensory integration and information processing would allow us to determine whether the reduction of motility following whole-body irradiation reflects effects on the central nervous system or on the muscle cells themselves...

INTRODUCTION: Innervated muscle transfer can improve functional outcomes after extensive limb-sparing sarcoma resections. We report our experience using composite thigh flaps for functional reconstruction of large oncologic extremity defects. PATIENTS AND METHODS: Between 2011 and 2014, four limb-sparing oncologic resections (3 lower extremities, 1 upper extremity) underwent immediate functional reconstruction with composite thigh free flaps in three males and one female...

When an auricular defect is caused by high-energy trauma that causes damage to the surrounding tissues, the patient may be not a candidate for reconstruction with local flaps and free tissue transfer may be necessary. Here we present a case of total auricular reconstruction in a 27 year-old man who had total loss of the left ear and traumatized temporal skin and fascia. A radial forearm flap prelaminated by a porous polyethylene implant was employed. A "printed" ear made of silicone, based on the patient's CT-scan of the contralateral ear, was used for intraoperative molding of the future reconstruction...

BACKGROUND: Non-traumatic radial nerve palsy (RNP) caused by local tumors is a rare and uncommon entity. METHODS: A 62-year-old female presented with a left non-traumatic RNP, initially starting with weakness only. It was caused by a benign giant lipoma at the proximal forearm that was misdiagnosed over a period of 2 years. The slowly growth of the tumor led to an irreparable overstretching-related partial nerve disruption. For functional recovery of the patient, a triple tendon transfer procedure had to be performed...

PURPOSE: The state-of-the-art tendon transfer surgery for high median-ulnar nerve palsy involves directly suturing four finger flexor tendons to one wrist extensor muscle. This couples finger flexion limiting the patient's ability to grasp objects. Therefore, we propose a new approach to attach a novel passive implant to the extensor digitorum longus tendon in order to create a differential mechanism in situ. The implant is expected to enable the fingers to adapt to an object's shape during grasping...

We found that the orally administered thermolysin digest of β-conglycinin exhibits antidepressant-like effects in tail suspension and forced swim tests in mice. A comprehensive peptide analysis of the digest using liquid chromatography/mass spectrometry was performed, and LSSTQAQQSY emerged as a candidate antidepressant-like peptide. Orally administered synthetic LSSTQAQQSY exhibited antidepressant-like effects at a dose of 0.3 mg/kg; therefore, we named the decapeptide soy-deprestatin. In contrast, intraperitoneally administered soy-deprestatin was ineffective...

We examined the vagal transfer function of autonomic heart rate (HR) control in anesthetized sedentary and exercise-trained Spontaneously Hypertensive Rats (SHR). To this end, male SHR and Wystar-Kyoto (WKY) rats with 48-50weeks of age-old were divided into 4 groups: sedentary (SHRS, n=12) and trained (SHRT, n=14) hypertensive rats, sedentary (WKYS, n=13) and trained (WKYT, n=13) normotensive rats. The trained groups were submitted to swimming protocol for 9weeks. Blood pressure (BP), HR, HR variability (HRV), BP variability (BPV), baroreflex sensitivity and cardiac tonus were recorded in baseline conditions...

BACKGROUND: Facial nerve palsy is a disabling condition that may arise from a variety of injuries or insults and may occur at any point along the nerve or its intracerebral origin. OBJECTIVE: To examine the use of the deep temporal branches of the motor division of the trigeminal nerve for neural reconstruction of the temporal branches of the facial nerve for restoration of active blink and periorbital facial expression. METHODS: Formalin-fixed human cadaver hemifaces were dissected to identify landmarks for the deep temporal branches and the tension-free coaptation lengths...

BACKGROUND: Dry eye disease (DED) affects one third of population worldwide. In prior studies, experimental autoimmune lacrimal keratoconjunctivitis (EALK) induced by desiccating stress in mice has been used as a model of DED. This model is complicated by a requirement for exogenous epithelial cell injury and the administration of anticholinergic agents that have broad immunological effects. OBJECTIVE: We sought to develop a novel mouse model of EALK, and to demonstrate the responsible immunological pathogenic mechanisms...

Porcine hemagglutinating encephalomyelitis virus (PHEV) is a highly neurovirulent coronavirus that invades the central nervous system (CNS) in piglets. Although important progress has been made towards understanding the biology of PHEV, many aspects of its life cycle remain obscure. Here, we dissected the molecular mechanism underlying cellular entry and intracellular trafficking of PHEV in mouse neuroblastoma (Neuro-2a) cells. We first performed a thin-section transmission electron microscopy (TEM) assay to characterize the kinetics of PHEV, and found that viral entry and transfer occur via membranous-coating-mediated endo-/exocytosis...
