The psychopathological influence of adolescent idiopathic scoliosis in korean male : an analysis of multiphasic personal inventory test results.

Objective: There are few published studies which have documented psychopathological abnormalities in patients with of adolescent idiopathic scoliosis (AIS) The aim of this study was to evaluate the psychopathological influence of AIS in Korean 19-year-old males.

Methods: The authors compared the Korean military multiphasic personal inventory (KMPI) military profiles of 105 AIS cases (more than 10 degrees of Cobb's angle without surgical treatment) with the KMPI profiles of 108 normal controls. The AIS group was split depending on Cobb's angle to further evaluate this relation by the severity of AIS.

Usefulness of chest radiographs for scoliosis screening: a comparison with thoraco-lumbar standing radiographs.

Purpose: The purposes of this study were to evaluate the usefulness and limitations of chest radiographs in scoliosis screening and to compare these results with those of thoraco-lumbar standing radiographs (TLSR).

Materials And Methods: During Korean conscription, 419 males were retrospectively examined using both chest radiographs and TLSR to confirm the scoliosis and Cobb angle at the Regional Military Manpower. We compared the types of spinal curves and Cobb angles as measured from different radiographs.

The psychopathological influence of congenital heart disease in Korean male adolescents: an analysis of multiphasic personal inventory test results.

Purpose: The aim of this study was to evaluate the psychopathological influence of congenital heart disease (CHD) in Korean 19-year-old males.

Materials And Methods: The authors compared the Korean military multiphasic personal inventory (KMPI) military profiles of 211 CHD cases (atrial septal defect, ventricular septal defect, patent ductus arteriosus, or combined CHD) with the KMPI profiles of 300 normal controls. The CHD group was also divided according to whether or not the subjects had undergone open cardiac surgery in order to evaluate the psychopathological effects of an operation among the subjects.

Lumbar disc screening using back pain questionnaires: oswestry low back pain score, aberdeen low back pain scale, and acute low back pain screening questionnaire.

Objective: To evaluate the usefulness of back pain questionnaires for lumbar disc screening among Korean young males.

Methods: We carried out a survey for lumbar disc screening through back pain questionnaires among the volunteers with or without back pain. Three types of back pain questionnaire (Oswestry Low Back Pain Score, Aberdeen Low Back Pain Scale, and Acute Low Back Pain Screeing Questionnaire) were randomly assigned to the examinees.

Radiological Efficacy of Cervical Lateral Mass Screw Insertion and Rod Fixation by Modified Magerl's Method (Yoon's Method) with Minimum 2 Years of Follow-up.

Objective: Cervical lateral mass screw insertion and rod fixation is a useful method for stabilizing the cervical disease, so various modified techniques were present. Many surgeons had reported the biomechanical safety according to the screw positioning method in the cervical spine, but the modified Magerl's method (Yoon's method) was not well studied. So, this study assessed the radiological efficacy of the modified Magerl's method with long-term follow-up.

Missed diagnosis of syrinx.

Study Design: Prospective, randomized, controlled human study.

Purpose: We checked the proportion of missed syrinx diagnoses among the examinees of the Korean military conscription.

Overview Of Literature: A syrinx is a fluid-filled cavity within the spinal cord or brain stem and causes various neurological symptoms.

Prevalence of Lumbar Disc Herniation in Adolescent Males in Seoul, Korea: Prevalence of Adolescent LDH in Seoul, Korea.

Objective: The authors surveyed the prevalence and the clinical character of lumbar disc herniation (LDH) in Korean male adolescents, and the usefulness of current conscription criteria.

Methods: The data of 39,673 nineteen-year-old males that underwent a conscription examination at the Seoul Regional Korean Military Manpower Administration (MMA) from October 2010 to May 2011 were investigated. For those diagnosed as having lumbar disc herniation, prevalences, subject characteristics, herniation severities, levels of herniation, and modified Korean Oswestry low back pain disability scores by MMA physical grade were evaluated.

Primary paravertebral low-grade fibromyxoid sarcoma.

The authors report a 58-year-old woman with low-grade fibromyxoid sarcoma primarily located in the right paravertebral area with extension to L4 neural foramen. The patient complained lower back pain with radiating pain along the posterolateral aspect of the right lower leg. She underwent subtotal surgical removal and Cyber Knife therapy.

Comparative Study of Outcomes between Shunting after Cranioplasty and in Cranioplasty after Shunting in Large Concave Flaccid Cranial Defect with Hydrocephalus.

Objective: The cranioplasty and ventriculoperitoneal (VP) shunt operation have been used to treat a large cranial defect with posttraumatic hydrocephalus (PTH). The aim of this study was to evlauate the difference of outcomes between in the shunting after the cranioplasty (group 1) and the cranioplasty after the shunting (group 2) in a large flaccid cranial defect with PTH.

Apoptotic change in response to magnesium therapy after moderate diffuse axonal injury in rats.

The biochemical factors related to moderation of secondary or delayed damage to the central nervous system (CNS) remain undefined. We have recently demonstrated that the weight- drop induced moderate diffuse axonal injury (mDAI) in rats causes a rapid decline in serum ionized magnesium (Mg(2+)) and a significant increase in the amount of serum ionized calcium (Ca(2+)) relative to Mg(2+) (Ca(2+)/ Mg(2+)). For three hours, serum Mg(2+) levels remained significantly depressed at 76% of preinjury values (p < 0.

Spinal epidural metastasis of cerebral oligodendroglioma.

A 50-year-old male patient with right frontal oligodendroglioma underwent subtotal resection on three separate occasions and, 10 months later, exhibited right frontal oligodendroglioma and extracranial metastasis. Spinal magnetic resonance imaging (MRI) demonstrated the existence of an enhancing mass lesion with evidence of posterior epidural compression at the 10th-11th thoracic level, not involving the vertebrae. A bone scan of the spine appeared normal, but showed evidence of hot uptake in the pelvis and femur.
