I have examined the effects of a growth factor, transforming growth factor(TGF)-B 1, on the rates of proteoglycan synthesis, aggregation potenital, and phenotypic expression of proteoglycans from human cervical intervertebral discs maintained in a cell culture system. A cell culture system for transitional and nuclear regions of degenerated human cervical intervertebral disc disc was devised to assess the biosynthetic response, assayed by 35S-sulfate incorporation into proteoglycan and protein synthesis assayed by 35S-methionine incorporation. And I had the data as the TGF-B 1 has an effect on the proteoglycan synthesis in quantitative and qualitative analysis in the cell culture system of the human intervertebral disc. TGF-B 1 may be used as a therapeutic alternative to degenerated disc disease.

We report a case of bacteriologically proven salmonella infection on the thoracic vertebra in a patient with previous history of pulmonary tuberculosis, in the non-endemic area with no history of sickle cell disease and typhoid fever. A forty-three years old female patient was admitted because of severe back pain, chest pain, lower extremity weakness and intermittent high fever elevation. On plain X-ray there was narrowing of T11-12 disc space with adjacent vertebral body destruction localized centrally around the disc and paravertebral abscess. She had an old history of pulmonary tuberculosis and treated with antituberculosis medication twenty years ago. We treated this patient by abscess drainage, anterior curettage and iliac corticocancellous strut bone graft over the T11 to T12 by anterior transthoracic approach. Histopathological diagnosis was chronic vertebral osteomyelitis with chronic inflammatory reaction. Pus culture reported to have grown salmonella typhi group D, sensitive to ampicillin, chloramphenicol, gentamicin and tetracycline. We could establish the diagnosis and effectively treat the disease with early surgical intervention.

PURPOSE: To evaluate the degree of injury of the spinal cord in relation with the space available for the spinal cord at the level of injury, the sagittal diameter of the spinal canal at the uninjured levels, and the Pavlov ratio at the uninjured levels in fractures and dislocations of the lower cervical spine. MATERIALS AND METHODS: We retrospectively reviewed the records and radiographs of patients who had sustained an acute fracture or dislocation of the cervical spine from 1990 to 1995. We collected patients from Orthopedic and Neurosurgical department of Chonbuk University Hospital and at Orthopedic department of Presbyterian Medical Center. Of the 69 patients analyzed, twelve had no neurological deficit, eleven had an isolated nerve-root injury, twenty-two had an incomplete injury of the spinal cord, and twenty-four had a complete injury. We measured above three parameters from the plain lateral radiographs and assessed the difference by one-way ANOVA and unpaired t-test. RESULTS: 1. The mean space available for the spinal cord at the level of injury was 12.9 millimeter for the complete injury of the spinal cord,13.8 millimeter for the incomplete injury, 14.7 millimeter for an isolated nerve-root injury, and 15.7 millimeter for no neurological deficit group. The overall difference among the groups was significant (F=6.98, P=0.0004). The patients who had a complete injury of the spinal cord and those who had an incomplete injury of the spinal cord were significantly different from the patients who had an isolated nerve-root injury and those who had no neurologic deficit (P=0.002). 2. The mean sagittal diameter of the canal at the proximal and distal uninjured level was 14.3 and 14.6 millimeter for the complete injury of the spinal cord, 14.9 and 14.9 millimeter for the incomplete injury, 15.5 and 16.6 millimeter for an isolated nerve-root injury, and 16.9 and 16.5 millimeter for no neurological deficit group. The patients who had a complete injury of the spinal cord and those who had an incomplete injury of the spinal cord were significantly different from the patients who had an isolated nerve-root injury and those who had no neurologic deficit (P=0.001). 3. The mean Pavlov ratio at the proximal and distal uninjured level was 0.90 and 0.86 for no neurologic deficit group, 0.85 and 0.87 for an isolated nerve-root injury, 0.76 and 0.75 for the incomplete injury of the spinal cord, and 0.76 and 0.76 for the complete injury. The patients who had a complete injury of the spinal cord and those who had an incomplete injury of the spinal cord were significantly different from the patients who had an isolated nerve-root injury and those who had no neurologic deficit (P=0.001). CONCLUSIONS: The patients who sustained a permanent injury of the cord usually had had a narrower sagittal diameter (<14mm) and a lower Pavlov ratio (<0.80) of the spinal canal before injury. Patients who had a large sagittal diameter of the canal may be more likely to be spared a permanent injury of the spinal cord following a fracture or dislocation of the cervical spine compared with patients who have a narrow canal. These findings demonstrated that the severity of the injury of the spinal cord was in part associated with the space available for the cord (at risk:<13mm) after the injury, as measured on plain lateral radiographs.

Wernickes encephalopathy is an illness characterized by mental disturbance, paralysis of eye movements and ataxia of gait. The specific factor for most, if not all, of these symptoms is a deficiency of thiamine. Wemicke's encephalopathy mostly occurs in developing countries when the patient is in a state such as nutritionally deprived state, anorexia nervosa, stomach cancer, long duration of parenteral nutrition. Wernickes encephalopathy was recognized as a complication of hyperemesis of pregnancy in 1914. Unfortunately, cases continue to occur. We present here a case of Wernickes encephalopathy in a 36-year-old pregnant woman. We discuss the clinical picture, histopathology, radiology, therapeutic management and prognosis with review of the literature.

PURPOSE: To determine the types of meniscal tears and type of popliteal muscle attachment in lateral disccid menisci. MATERIALS AND METHODS: MR images from 40 patients with arthroscopically proven disccid meniscal tears were reviewed. The type of capsular attachment of the popliteal muscle in these patients was compared with 100 normal controls. Fourteen men and 26 women were included in this study ranging in age from 8 to 52 yea rs. RESULTS: Disccid mensical tears were divided into five types. Arthroscopic cor- relation revealed that thirty-six cases(90%) of disccid meniscal tears were cor- rectly diagnosed using MR imaging. Peripheral tear wasthe commonest tear type occurring in 13 patients. In 9 of these the meniscal fragment was displaced. Hori- zontal tears occurred in 5, longitudinal tears in 4 and transverse tears in 2 patients. Multiple tears were present in 16 patients with the commonest combi- nation of peripheral and horizontal. Popliteal capsular attachments of disccid mensical tears were more prominent than in the normal control group. CONCLUSION: The types of tears in disccid menisci were different from normal meniscal tears. Peripheral detachment with displacement of torn segments was a very frequent finding in disccid mensical tears. Prominent capsular attachment of popliteal muscles is probably an associated finding in disccid menisci.

PURPOSE: Differential diagnosis of sexual precocity is important. Sexual precocity, defined as the appearance of secondary sexual characteristics before the age of 8 years in girls and 9 years in boys, was studied to evaluate the sex incidence and etiology of sexual precocity. METHODS: We reviewed the etiology and age incidence of precocious puberty in 14 boys and 89 girls examined between 1994. 11. 1-2002. 7. 31 at Samsung Seoul Hospital. All underwent standard anthropometric measures. They were assigned to diagnostic categories on the basis of clinical assessment, endocrine evaluation, radiologic imaging, and pelvic ultrasonography. RESULTS: In 89 girls, 27 had idiopathic precocious puberty, 3 had precocious puberty with organic brain lesion, 12 had gonadotropin-independent precocious puberty, 44 had premature thelarche, 2 had premature menarche, 1 had premature adrenarche. The majority of idiopathic precocious puberty girls(78%) were aged between 7-7.9 years. In 14 boys, 2 had idiopathic precocious puberty, 3 had precocious puberty with organic brain lesion, 6 had gonadotropin-independent precocious puberty, 3 had gynecomastia. CONCLUSION: Sexual precocity occurs more frequently in girls than boys. Premature thelarche is the most common form of sexual precosity. In boys, majority of central precocious puberty had organic brain lesion, so brain imaging study should be performed. In girls, majority of idiopathic precocious puberty were aged between 7-7.9 years. Reexamination of the age limit for defining when puberty should be considered precocious in Korean girls is necessary.
