OBJECTIVE: To investigate the effect of steroid administration on the apoptosis and heat shock protein 70 (HSP70) expression after exercise in the animal model of Duchenne muscular dystrophy. METHOD: We measured Bcl-2, BAX and HSP70 expression by western blotting. 20 control and 20 mdx mice were divided into free-living (n=10) and exercise (n=10) groups. Free-living and exercise groups were further divided into steroid-treated and sham-treated groups to evaluate the effect of steroid administration. RESULTS: Apoptosis was most prominent in the sham-treated exercise group, while apoptosis was significantly reduced in the steroid-treated exercise group. HSP70 expression was maximized in sham-treated exercise group, whereas steroid administration inhibited HSP70 expression after exercise in muscular dystrophy animal model. Exercise loading was found to cause severe apoptosis but steroid administration alleviated apoptotic damage in mdx mice. CONCLUSION: HSP70 expression was suppressed in the steroid-treated exercise group, which suggests steroid might have major preventive effect in exercise-induced apoptosis of muscular dystrophy animal model.

The population enjoying ski had increased since 1970's in Korea. Recently, that of snowboarders has increased rapidly among young population. Patterns of injuries are somewhat different between two sport activities. The most commonly injured region is knee among skiers and wrist among snowboarders. Head injury, spinal injury, and abdominal injury are not so common but a few serious injuries had been reported in Korea. To prevent or minimize injuries, proper pre-seasonal training including muscle strengthening, proper selection of equipments, and instruction for both sport technique and protection for safety are important. Also primary care for the injured as well as delivery system for seriously injured population should be established.

Rehabilitation is one of the five vital components of the healthcare system, along with prevention, promotion, treatment, and palliation. In Korea, inpatient rehabilitation service is inadequately supplied based on the low fee system for rehabilitation services and an absence of a standard for inpatient rehabilitation facility. Consequently, the length of hospital stays increases and the rate of successful post-rehabilitation return to the community is low. To provide intensive rehabilitation, US established ‘inpatient rehabilitation facility’ system and Japan established ‘restorative rehabilitation hospital system’. In 2020, a new accreditation system has been launched in South Korea with the aim to improve the country’s intensive inpatient rehabilitation services. This new system defines the standards of workforce management, facility, diagnostic category, comprehensive functional measure, onset and duration of inpatient rehabilitation, and fees for team conferences and social services for a successful return to the community. The system aims to achieve an effective and efficient inpatient rehabilitation system in Korea.

We report a case of a 53-year-old male with traumatic cervical spinal cord injury (SCI). He could not maintain a standing position because of painful spasticity in his lower limbs. A magnetic resonance imaging and electromyography indicated chronic lumbosacral radiculopathy, explaining his chronic low back pain before the injury. For diagnostic as well as therapeutic purposes, transforaminal epidural steroid injection (ESI) to the right L5 root was performed. After the intervention, the spasticity decreased and his ambulatory function improved. This case illustrates that lumbar radiculopathy concomitant with a cervical SCI can produce severe spasticity and it can be dramatically improved by ESI.

Endoscopic sphincterotomy (E.S.T.) has relatively low complications and is the theraphy of choice in patients with common bile duct stones. It is also an useful technique for decompression of biliary tract obstruction. Thirty two cases of patients were selected according to opedrative risks: old age, severe jaundice and recurrent or retained bile duct stones after cholecystecomy from 1986 to 1988. The results were as follows, 1) In thirty two cases nf E.S.T., male to female ratio was 1:1.46. Most frequent age was older than 40 years. (male, 84.6%, female, 84.2%). 2) Out of thirty two cases, 20 cases (62.5% were under post clholecystectomy state, 12 eases (37.5%) were obstructive jaundice. 3) Spontaneous stone passage after E.S.T. was 81.3% (26 cases), and total stone remoral rate was 87.5% (28 cases), 4) Complications of E.S.T. were noted in three cases. In the two cases of bleeding, it was spontaneously improved and a case of acute pancreatitis was treated by medical care.

We report on operational and rehabilitation management, as well as the outcome, of a patient who with sustained spinal cord injury from a high velocity gunshot wound to the lumbar spine. More specifically, a patient with a gunshot wound to the spine is more likely to sustain a complete injury and have a poor prognosis. As such, there should be concerns regarding associated and extended injuries related to bullet fragmentation as well as the possibility of long-term sequelae.

We report a 13 year-old female child with a idiopathic acute sensory neuronopathy mimicking a sensory form of Guillain-Barr syndrome, identified with electrodiagnosis and spine MRI. Motor conduction results were normal, but sensory nerve action potentials were not evoked in all four extremities. On MRI of the whole spine, the diffuse gadolinium-enhancement of dorsal roots in the spinal canal was detected without evidence of intramedullary lesion. The clinical symptoms and electrodiagnostic abnormalities had persisted for more than 18 months follow-up.
