BACKGROUND: Herpes zoster is an illness which is especially common amongst the elderly in the Netherlands and which can express itself in various ways. Besides affecting sensory nerves, which leads to postherpetic pain, the varicella zoster virus may also invade motor nerves. CASE DESCRIPTION: A 73-year-old female went to the surgeon with symptoms of a painful swelling in the left lower abdomen. She had experienced herpes zoster at the site of the swelling a few months earlier...

The use of pectoralis major muscle (PMM) in breast reconstruction has been a mainstay for decades. In recent years, although, a novel approach, the so-called subcutaneous or pre-pectoral breast reconstruction, has been introduced advocating the advantages of sparing the pectoralis muscle. Such advantages include more natural implant ptosis and appearance, significant reduction of capsular contracture and also avoidance of implant animation and animation deformities. These are all drawbacks that the use of muscles in implant coverage inevitably involves overtime...

Functional Electrical Stimulation (FES) can elicit muscular contraction and restore motor function in paralyzed limbs. FES is a rehabilitation technique applied to various sensorimotor deficiencies and in different functional situations, e.g. grasping, walking, standing, transfer, cycling and rowing. FES can be combined with mechanical devices. FES-assisted cycling is mainly used in clinical environments for training sessions on cycle ergometers, but it has also been adapted for mobile devices, usually tricycles...

INTRODUCTION: The most common form of spinal muscular atrophy (SMA) is a recessive disorder caused by SMN1 mutations in 5q13, whereas the genetic etiologies of non-5q SMA are very heterogenous and largely remain to be elucidated. We present a father and son with atrophy and weakness of the lower leg muscles since infancy. Genetic studies in this family revealed a novel BICD2 mutation causing autosomal dominant lower extremity-predominant SMA type 2. PATIENTS: The proband was the father, aged 30, and the son was aged 3...

PURPOSE: Decrease in activity stress induces skeletal muscle atrophy. A previous study showed that treatment with a high level (20%) of isoflavone inhibits muscle atrophy after short-term denervation (at 4 days) in mice. The present study was designed to elucidate whether the dietary isoflavone aglycone (AglyMax) at a 0.6% prevents denervation-mediated muscle atrophy, based on the modulation of atrogin-1- or apoptosis-dependent signaling. METHODS: Mice were fed either a normal diet or 0...

BACKGROUND: The surgical microscope is an essential tool for microsurgery. Nonetheless, several promising alternatives are being developed, including endoscopes and laparoscopes with video systems. However, these alternatives have only been used for arterial anastomoses so far. The aim of this study was to evaluate the use of a low-cost video-assisted magnification system in end-to-side neurorrhaphy in rats. MATERIALS AND METHODS: Forty rats were randomly divided into four matched groups: (1) normality (sciatic nerve was exposed but was kept intact); (2) denervation (fibular nerve was sectioned, and the proximal and distal stumps were sutured-transection without repair); (3) microscope; and (4) video system (fibular nerve was sectioned; the proximal stump was buried inside the adjacent musculature, and the distal stump was sutured to the tibial nerve)...

OBJECTIVE: After recurrent laryngeal nerve injury (RLN), spontaneous reinnervation of the larynx occurs with input from multiple sources. The purpose of this study was to determine the timing and efficiency of reinnervation across a resected RLN segment in a rat model of RLN injury. STUDY DESIGN: Animal study. METHODS: Twelve male 60-day-old Sprague Dawley rats underwent resection of a 5-mm segment of the right RLN. Rats were sacrificed at 1, 2, 4, and 12 weeks after nerve injury to harvest the larynx and trachea for immunohistologic analysis...

OBJECTIVES/HYPOTHESIS: In animal studies, intramuscular vincristine injections have been shown to block reinnervation of the denervated target muscle. This application could be used selectively to influence recovery patterns following injury of recurrent laryngeal nerves (RLNs). However, vincristine is currently Food and Drug Administration approved only for intravenous use. A formal toxicity trial of intramuscular injections was performed. STUDY DESIGN: Animal study...

Muscle atrophy results in severe functional impairment and is a significant clinical problem. We examined and characterized the therapeutic effects of autologous adipose-derived stem cells (ADCSs) using an in vivo muscle atrophy rat model. To identify the effect of injected ADSCs into muscle, we developed the following two models of muscle atrophy in rats: induction of denervation by sciatic nerve defects; and nerve repair after severing the sciatic nerve. The inguinal fat pads were harvested from each rat and autologous ADSCs were cultured and ADSCs were injected in the right hind limbs as the experimental group, while normal saline was injected in the left hind limbs, which served as the control group...

Background: Functional free gracilis muscle transfer is an operative procedure for elbow reconstruction in patients with complete brachial plexus nerve and avulsion injuries and in delayed or prolonged nerve denervation, as well as in patients with inadequate upper extremity function after primary nerve reconstruction. Methods: We retrospectively reviewed our patient records and identified 24 patients with complete brachial plexus nerve injury (13 obstetric, 11 males and 2 females; 11 traumatic, 9 males and 2 females) whose affected arm and shoulder were totally paralyzed and their voluntary elbow flexion or the biceps function was poor preoperatively (mean M0-1/5 in MRC grade)...

Background and Objective: This study aims to determine the period of reinnervation in patients with poliomyelitis. This research was conducted to identify the appearance of denervation potentials in patients with poliomyelitis as indicators for reinnervation. Materials and Methods: A total of 246 male patients with poliomyelitis were assessed electrophysiologically between 1988 and 2007. The mean age was 22.8 (18-42). It has been an average of 19.9 ± 4.9 years since the beginning of complaints from the patients...

Duchenne muscular dystrophy is the most common and severe of the muscular dystrophies, a group of inherited myopathies caused by different genetic mutations leading to aberrant expression or complete absence of cytoskeletal proteins. Dystrophic muscles are prone to injury, and regenerate poorly after damage. Remorseless cycles of muscle fibre breakdown and incomplete repair lead to progressive and severe muscle wasting, weakness and premature death. Many other conditions are similarly characterized by muscle wasting, including sarcopenia, cancer cachexia, sepsis, denervation, burns, and chronic obstructive pulmonary disease...

Skeletal muscle atrophy, or sarcopenia, is commonly observed in older individuals and in those with chronic disease and is associated with decreased quality of life. There is recent medical and broad concern that sarcopenia is rapidly increasing worldwide as populations age. At present, strength training is the only effective intervention for preventing sarcopenia development, but it is not known how this exercise regimen counteracts this condition. Here, we report that expression of the inflammatory mediator angiopoietin-like protein 2 (ANGPTL2) increases in skeletal muscle of aging mice...

Targeted muscle reinnervation (TMR) is a novel surgical technique developed to improve the control of myoelectric upper limb prostheses. Nerves transected by the amputation, which retain their original motor pathways even after being severed, are redirected to residual denervated muscles that serve as target for consequent reinnervation. Once the process is complete, reinnervated muscles will contract upon voluntary activation of transferred nerves while attempting to move missing regions of the amputated limb, generating EMG signals that can be recorded and used to control a prosthetic device...

Locomotion outcomes after peripheral nerve injury and repair in cats have been described in the literature for the period immediately following the injury (muscle denervation period) and then again for an ensuing period of long-term recovery (at three months and longer) resulting in muscle self-reinnervation. Little is known about the changes in muscle activity and walking mechanics during mid-recovery, i.e. the early reinnervation period that takes place between 5 and 10 weeks of recovery. Here, we investigated hindlimb mechanics and EMG activity of ankle extensors in six cats during level and slope walking before and every two weeks thereafter in a 14-week period of recovery after the soleus (SO) and lateral gastrocnemius (LG) muscle nerves in one hindlimb were surgically transected and repaired...

This study explored the efficacy of shear wave ultrasound elastography (SWUE) for quantitative evaluation of denervated muscle atrophy in a rabbit model. The elastic modulus of the triceps surae muscle was measured with SWUE and compared with histopathologic parameters at baseline and at various post-denervation times (2, 4 and 8 wk) with 10 animals in each group. Our results revealed that the elastic modulus of denervated muscle was significantly lower at 2 wk but higher at 8 wk compared with that at the baseline (p <0...

Guillain-Barré syndrome (GBS) is an immune-mediated polyradiculoneuropathy with acute onset and rapid clinical worsening; early diagnosis and immunomodulating therapy can ameliorate the course of disease. During the first days, however, nerve conduction studies (NCSs) are not always conclusive. Here, we describe a 73-year-old man presenting with progressive muscular weakness of the lower limbs, ascending to the upper limbs, accompanied by distal sensory disturbances. Neuroimaging of brain and spine and NCSs were unremarkable; cerebrospinal fluid analysis revealed no albuminocytologic dissociation...

Stem cell therapy is considered a promising approach in the treatment of amyotrophic lateral sclerosis (ALS) and mesenchymal stem cells (MSCs) seem to be the most effective in ALS animal models. The umbilical cord (UC) is a source of highly proliferating fetal MSCs, more easily collectable than other MSCs. Recently we demonstrated that human (h) UC-MSCs, double labeled with fluorescent nanoparticles and Hoechst-33258 and transplanted intracerebroventricularly (ICV) into SOD1G93A transgenic mice, partially migrated into the spinal cord after a single injection...

INTRODUCTION: Volumetric muscle loss (VML) occurs following significant traumatic injury or surgical removal of skeletal muscle, resulting in non-recoverable loss of tissue and long-term dysfunction. Perhaps less recognized is that VML injuries inherently disrupt the neuromuscular unit, resulting in fiber denervation and presumptive motor unit rearrangement, expansion, and/or loss. To characterize neural dysfunction we quantified motoneuron axotomy, in efforts to understand how this relates to the temporal coordination of neuromuscular and morphological alterations due to injury...
