BACKGROUND: Isolated tuberculous tenosynovitis and bursitis are rare among musculoske let al tuberculosis, but it is one of the major causes for chronic tendon sheath infection in developing countries. In hand, it is usually presented as a compound palmer ganglion (radio ulnar bursa), tenosynovitis of the flexer tendon sheaths and very few cases of tubercular tenosynovitis affecting the extensor tendons also are reported. CASE PRESENTATION: We are reporting a rare case of tuberculous extensor tenosynovitis with rupture of the extensor digitorum tendon in an elderly Indian man...

BACKGROUND: We evaluated whether cardiac autonomic changes could be associated with different extent of sympathetic nerve resection in the management of essential palmar hyperhidrosis. METHODS: Sixty patients with essential palmar hyperhidrosis were randomly allocated to undergo excision of T3 ganglia (sympathicectomy group; n = 30) or to interruption of sympathetic chain at the T2 to T3 level with ganglion sparing (sympathicotomy group; n = 30). Time and frequency domains were measured with a 24-Holter monitor during daytime, nighttime, and 24-hour periods at different interval points (7 days before operation; 24 hours; and 1, 3, and 6 months later), and the differences were statistically compared...

Characterizing the role of epigenetic regulation in the mammalian retina is critical for understanding fundamental mechanisms of retinal development and disease. DNA methylation, an epigenetic modifier of genomic DNA, plays an important role in modulating networks of tissue and cell-specific gene expression. However, the impact of DNA methylation during retinal development and homeostasis of retinal neurons remains unclear. Here, we have created a tissue-specific DNA methyltransferase (Dnmt) triple mutant mouse in an effort to characterize the impact of DNA methylation in retinal development and homeostasis...

Chemotherapy-induced neurotoxicity of peripheral nervous system (PNS) hinders efficacy of cancer treatments. Mechanisms initiating PNS injury by anticancer drugs are incompletely understood delaying development of effective management strategies. To understand events triggered in PNS by cancer drugs, we exposed dorsal root ganglion (DRG) neurons to cisplatin, a drug from platinum-based class of chemotherapeutics frequently implicated in peripheral neuropathies. While cisplatin enters cancer cells and forms cisplatin/DNA crosslinks that block cell proliferation, circulating cisplatin can also reach the PNS and produce crosslinks that impede critical DNA transactions in postmitotic neurons...

Tissue ischemia results in an accumulation of lactate and local or systemic lactic acidosis. In nociceptive sensory neurons, lactate was reported to sensitize or activate the transient receptor potential ion channel TRPA1 and acid-sensing ion channels (ASICs). However, it is unclear how lactate modulates the TRPV1 regarded as the main sensor for acidosis in sensory neurons. In this study we investigated the effects of lactate (LA) on recombinant and native TRPV1 channels and on TRPV1-mediated release of neuropeptides from mouse nerves...

At present, primary hyperhidrosis is the main indication for sympathectomy. For upper thoracic sympathetic ablation, excision of the second thoracic ganglion alone or with the first and/or third ganglia was the standard during the open surgery era. With the advent of thoracoscopy, modifications related to the level, extent, and type of ablation were proposed to attenuate compensatory hyperhidrosis. The ideal operation for sympathetic denervation of the face and upper limbs remain to be defined. Controlled double-blind studies with quantitave measurements of sweat production are required...

Peripheral neuropathies caused by ganglion cysts are quite rare, especially in the lower extremities. The case of a 64-year-old male with a 2-day history of foot drop and tenderness in the region of the left fibular neck is presented. Physical examination and electromyogram findings verified peroneal nerve palsy. Ultrasonography showed cystic mass localized proximal of the peroneal muscle structures. Magnetic resonance imaging revealed a cystic-appearing mass around the fibular neck that compressed the common peroneal nerve...

BACKGROUND: Tumors of the middle fossa or cavernous sinus (CS), or intraorbital tumors, can penetrate each other through the superior orbital fissure (SOF) or neighboring tissue. These complicated pathologies are often treated with highly invasive surgical procedures. In this article, we demonstrate surgical anatomic dissections of the CS, SOF, orbital apex (OA), and dura mater extending to the periorbita from the middle fossa, by performing an epidural dissection via a lateral orbitotomy approach, and discuss findings that may provide guidance during surgery in these regions...

INTRODUCTION: Hand tumours are frequently encountered in clinical practice. A list of differential diagnoses of the most common hand tumours based on anatomical location would be helpful for clinicians. We aimed to determine the anatomical distribution of hand tumours seen at a hand surgery practice in Singapore. METHODS: The medical records of 50 men and 65 women (mean age 41.7 [range 17-74] years) who underwent excision of hand tumours between 1 June 2010 and 31 December 2012 were reviewed...

INTRODUCTION: Two types of ganglion cysts at the elbow have been described depending on their anatomic location. Type A ganglion cyst is located proximal to the arcade of Frohse, and type B distal to it. Compressive neuropathies of the radial nerve at the level of the radial tunnel may lead to two different clinical entities with different clinical manifestations. These different conditions depend on which branch is involved. Although compression of the deep motor branch due to a ganglion cyst has been previously described, affection of the superficial sensory branch is considered much rarer...

INTRODUCTION: Ganglion cysts are benign soft tissue swellings commonly found in the wrist. The presence of these cysts in the elbow is uncommon, and few case reports have been reported for this condition at this location. These lesions can compress on the neighbouring structures or cause restriction of the joint movement. The awareness of this entity is a must, to arrive at an early diagnosis. MATERIALS AND METHOD: We report a patient with swelling in the anterolateral aspect of the elbow which had been causing intermittent pain for the last 13 months...

Nestin-expressing stem cells of the hair follicle, discovered by our laboratory, have been shown to be able to form outer-root sheaths of the follicle as well as neurons and many other non-follicle cell types. We have termed the nestin-expressing stem cells of the hair follicle as hair-follicle-associated pluripotent (HAP) stem cells. We have shown that the HAP stem cells from the hair follicle can effect the repair of peripheral nerve and spinal cord injury. The hair follicle stem cells differentiate into neuronal and glial cells after transplantation to the injured peripheral nerve and spinal cord, and enhance injury repair and locomotor recovery...

Cadmium (Cd) and lead (Pb) are both highly toxic metals in environments. However the toxicological mechanism is not clear. In this study, the aplysiid, Notarcus leachii cirrosus Stimpson (NLCS) was subjected to Cd (NLCS-Cd) or Pb (NLCS-Pb). The cerebral ganglion of NLCS was investigated with a transmission electron microscope. Next the differential proteins were separated and identified using proteomic approaches. Eighteen protein spots in NLCS-Cd and seventeen protein spots in NLCS-Pb were observed to be significantly changed...

Long-term spinal cord stimulation (SCS) applied to cranial thoracic SC segments exerts antiarrhythmic and cardioprotective actions in the canine heart in situ. We hypothesized that remodeling of intrinsic cardiac neuronal and synaptic properties occur in canines subjected to long-term SCS, specifically that synaptic efficacy may be preferentially facilitated at high presynaptic nerve stimulation frequencies. Animals subjected to continuous SCS for 5-8 weeks (long-term SCS: n = 17) or for 1 h (acute SCS: n = 4) were compared with corresponding control animals (long-term: n = 15, acute: n = 4)...

Ganglion cysts originating from the anterior cruciate ligament (ACL) are uncommon. Often asymptomatic, they infrequently present with non-specific symptoms such as knee pain, stiffness, clicks, locking or restriction of knee extension. However, the patient we report presented with knee flexion restriction. A 37-year-old Chinese gentleman, with no history of knee trauma, presented with left knee pain. Left knee range of motion (ROM) was from 0 to 110 degrees. Magnetic resonance imaging (MRI) scan revealed a 1...

The present study was conducted to elucidate the neuronal pathways between peripheral olfactory and taste sensilla and the synganglion in an Ixodidae tick species. The tarsus of the front legs (olfactory nerves) and the fourth palpal segment (gustatory nerves) of unfed Amblyomma americanum males and females were excised. A neuronal tracer, dextran tetramethylrhodamine, was used for filling of the sensory neurons. The synganglion preparations were examined using a confocal microscope. Neuronal arborizations from the Haller's organ were confined to the olfactory lobes and the first pedal ganglion...

INTRODUCTION: Intra-articular ganglion cysts of the knee joint are rare occurrences. They are usually encountered as incidental findings in magnetic resonance imaging (MRI), or in arthroscopy. They may originate from both the cruciate ligaments and the menisci, from the popliteus tendon and alar folds, infrapatellar fat pad of Hoffa, and subchondral bone cysts. Those arising from the Hoffa's fat pad, usually present as palpable mass at anterior aspect of the knee joint. We report a case of intraarticular ganglion cyst of knee arising from the infrapatellar fat pad and protruding anterolaterally through retinacular rent into the subcutaneous plane...
