PURPOSE: To examine the incidences and patterns of injuries that required medical attention among Asian football players. METHODS: A total of 411 Asian football players at both senior and youth (U-20) elite levels were observed during 50 international matches. Independent injury observers and team doctors determined the occurrence of injuries and recorded the location, type, time, and circumstances of the injuries using a protocol sheet. RESULTS: The overall injury frequency rate was 45.8 out of

Our findings suggest that PEN is an effective treatment for back and leg pain caused by single-level LDH, with the outcomes remaining unaffected by the LDH type.

PEN is an effective procedure in treating single level lumbar disc herniation without affecting dural sac cross-sectional area.

Background . The correlation between epidurography contrast patterns and the clinical outcomes of percutaneous epidural neuroplasty (PEN) remains unclear. Objective . To analyze the correlation between postadhesiolysis epidurography contrast patterns and the clinical outcomes of patients who undergo lumbar PEN. Design . This study is a retrospective analysis of 78 consecutive patients who underwent lumbar PEN between April 2012 and March 2013. Setting . The analysis was done in the university ho

The herniated lumbar disc (HLD) in adolescent patients is characterized by typical discogenic pain that originates from a soft herniated disc. It is frequently related to back trauma, and sometimes it is also combined with a degenerative process and a bony spur such as posterior Schmorl's node. Chemonucleolysis is an excellent minimally invasive treatment having these criteria: leg pain rather than back pain, severe limitation on the straight leg raising test (SLRT), and soft disc protrusion on

✓ The purpose of this paper was to present two cases of secondary trigeminal neuralgia (TN) with an unusual origin and lesion location. In two cases TN was caused by lesions along the course of the trigeminal nerve within the pons and adjacent to the fourth ventricle. Both cases presented with typical TN. Brain magnetic resonance imaging revealed linear or wedge-shaped lesions adjacent to the fourth ventricle, extending anterolaterally and lying along the pathway of the intraaxial trigeminal fib

The purpose of this study was to examine the incidences and patterns of injuries, requiring medical attention, in Asian youth soccer players. 24 international matches between teams at youth elite levels were obsereved. Independent injury observers and team doctors recorded the occurrence, location and type of injuries. The data collected were later cross-tabulated in an interview session usually held within 12 hours after match. The overall injury frequency rate(IFR) was 144.3/1,000 hours in inj

Glutamine synthetase (GS) is a key enzyme in the regulation of glutamate neurotransmission in the central nervous system. It is responsible for converting glutamate to glutamine, consuming one ATP and NH3 in the process. Glutamate is neurotoxic when it accumulates in extracellular fluids. We investigated the effects of GS in both a spinal cord injury (SCI) model and normal rats. 0.1-ml of low (2- micro M) and high (55- micro M) concentrations of GS were applied, intrathecally, to the spinal cord

We present a case of a spinal extradural AVF which occurred after instrumented lumbar interbody fusion and was completely closed by transarterial embolization with N-butylcyanoacrylate (Histoacryl, B. Braun). To our knowledge, endovascular treatment of spinal extradural AVFs arising after surgery has not been reported so far. This 49-year-old man presented with lower-extremity paresis, urinary retention, and sexual dysfunction of 3 months’ duration. He had undergone laminectomies at L3‐4 and L4‐

2 The risk of bleeding during the operation(especially bleeding from the hemiazygous vein could be reduced in the T2 sympathectomy group. 3 The treatment effect of T2 sympathectomy is no different from T2 T3 sympathectomy for essential palmar hyperhidrosis. 4 The incidence of compensatory hyperhidrosis is less in the T2 sympathectomy group than in the T2 T3 sympa- thectomy group. From the above results I concluded thoracoscopic transthoracic sympathectomy is the treatment of choice for essential

Objective：Comparing to cerebral cavernoma, spinal intramedullary cavernoma is rare. But, spinal intramedullary cavernomas are increasingly recognized after introduction of magnetic resonance image. The purpose of this study is to define the spectrum of presenting symptoms and signs in patients with intramedullary cavernomas and to analyze the role of surgery as a treatment for these lesions. Methods：The authors reviewed retrospectively the cases of 13 patients who underwent surgery for intrame
