1.Neurilemmoma: A Dome-lesion on the Palm.
Korean Journal of Dermatology 1998;36(6):1101-1102
We report a solitary neurilemmoma on the left palm that occured in a 19-year-old man. The mass was a 1 * 1.2 * 0.7cm sized dome which was located between the thenar and hypothenar on the left palm. A biopsy specimen showed histological findings consistent with neurilemmoma:circumscribed nuclear palisading with Verocay bodies.

The discovery and synthesis of vitamin D and the elucidation of the role of sunlight in the activation of the vitamin D precursors changed the syndromes of rickets from a therapeutic enigma to a socioeconomic and public health problem. Since Albright in 1937 first described vitamin D resistsnt rickets, which did not respond to treatment with the usual dose of vitamin D, it has progressively become a common form of rickets in practice. In addition, as the result of increasing understanding of renal physiology and careful investigation, a spectrum of renal tubular abnormalities have been identified which cause clinical rickets and which in many cases are insensitive to even large doses of vitamin D. We have reported a case of an unusual form of vitamin D resistant rickets which did not easily respond to treatment with high doses of vitamin D and was associated with hypocalcemia in multiple pathologic fractures in the lower extremities of the patient.

The Journal of the Korean Orthopaedic Association 1979;14(1):27-33
Among previously proposed etiological factors of chondromalacia patellae, abnormality in the extensor mechanism of the knee joint has been attributed as a cause of chondromalacia patellae by many authors Malalignment in the extensor mechanism of the knee joint is supposed to cause the positional change of patella. This positional change of patella can be measured by Q angle and P/PT ratio. Hereby we intened to classify the relationahip between the above measurement lenoting the positional change of patella and chondromalacia patellae. These values were obtained from 60 patients found to have chondromalacia patellae in Han Gang Sacred Heart Hospital, from Jan. 1977 to Sep. 1978. Values were also obtained from 60 normal persons as a control group. Thus a statistical analysis was made for the possible relationship between extensor mechanism of the knee joint and chondromalacia patellae. The following conclusion were made, 1. The sex ratio was 1:1.3 with female preponderance. There was 26 male and 34 female patients, common age group of chondromalacia patellae was age 20-40 years. 2. The average value of Q angle was 11 in control group, while 18 in chondromalacia patellae, having the difference of 7. 3. The average values of Q angle among different sexes were reviewed. The male control group had 9 of average value of Q angle, while male chondromalacia patellae had 16. The female control group had 12 of average value of Q angle, while female chondromalacia patellae had 20. 4. The average value of P/PT ratio was 1.03 in control group, while 0.9 in chondromalacia patellae, having the difference 0.13. For P/PT ratio in different sexes, the average value was 1.01 in male control group. while 0.9 in male chondromalacia patellae. The average value of P/PT ratio was 1.04 in female control group, while 0.89 in female chondromalacia patellae, 5. For statistical survey for these differences, P value was examined by t-test methods. The statistical diffrences of Q angle in male control group and chondromalacia patellae was 3.4 and it was 2.06 in he female. The difference between control group and the chondromalacia patellae in the overall seves was 2.61, thus having statistical significance.

6.Proximal Migration of the Intramedullary Nail in Fracture of the Femur

Various devices have been introduced in the field of orthopaedic surgery for the treatment of fractures and dislocations. Widely used among these are metallic nails and pins. A rare complication is the migration of such intermal fixation devices from their original sites of insertion. Examples of migration have been shown in cases for which devices like Kirschner wire and Steinmann pin were used. Acromio-clavicular joint dislocation gives us another good example. Kuntscher nail has beenin worldwide use for the treatment of femoral shaft fractures since the original work of Kuntscher in 1940. Yet few cases were reported, for migration & Kuntscher nail. We, recently had an experience of proximal migration of a Kuntscher nail in a femoral shaft fractnre which was markedly comminuted. The case is presented here with references.

BACKGROUND: The prevention of preterm deliveries still remains a major problem in ob-stetrics. The cause of preterm labor is poorly understood. Our purpose was to determine the risk factors for preterm labor associated with specific clinical and environmental factors. METHODS: Using a case-control design, 54 women with preterm labor and 134 controls with term labor, who were admitted to the department of Obstetrics and Gynecology, Dan- kook University Hospital from January, 1996 to August, 1996. The study groups were inte- rviewed and their medical records were reviewed. RESULTS: 1. There were no significant differences of maternal age, maternal weight at 20 weeks of gestation and maternal weight gain at the time of delivery. 2. There were no significant differences between housewives and working women. But the physical workload of the preterm labor group was significantly higher than the control group ( 16.0% vs. 4.0% ). 3. There were no significant differences in the smoking habit of mother or her husba- nd. The passive smoking of the preterm labor group was significantly higher than the con- trol group ( 43.8% vs. 26.8% ). 4. In vaginal bleeding at pregnancy, the preterm labor group was significantly higher than the control group ( 15.7% vs. 2.3% ). Especially, the third trimester vaginal bleeding of the preterm labor group was significantly higher than the control group. 5. There were no significant differences in the number of previous fullterm deliveries, previous abortions, and living children between two groups. The experience of the previous preterm deliveries of the preterm group was significantly higher than the control group ( 11. 5% vs. 0.8% ). 6. There were no significant differences of medications, consumption of alcohol, coffee, tea, green-tea, cola and nutritional beverages, the experiences of coitus, defecation numbers and accidents during pregnancy between two groups. 7. There were no significant differences in the plasma concentrations of hemoglobin, hematocrit, white blood cells, and in the blood pressure, and the body temperature between two groups. CONCLUSION: The risk factors of preterm labor were severe physical workload, vaginal bleeding at pregnancy, especially, the third trimester vaginal bleeding, and the experience of previous preterm deliveries.

Journal of Korean Society of Spine Surgery 1997;4(2):357-364
Synovial cysts are uncommon lesions that may occur within the spinal canal. Most commonly synovial cysts arise from degenerative apophyseal joints, in particular at the L4-5 level, and are associated with spondylolisthesis. We present one case of lumbar synovial cyst located both intraspinally and extraspinally and originated from the defect of the pars interarticularis. The content of the synovial cyst was infected. The patient progressively developed low back pain and fever. The lesion was diag nosed by computed tomography and a magnetic resonance imaging. The synovial cyst was presented a huge lobulacted intraspinal and extraspinal mass and connected with the L4-5 facet joint on the right side. The dural sac was displaced by the intraspinal mass. Relieve of symptoms was achieved with decompressive laminectomy and removal of the mass. The content of the synovial cyst was infected with Staphylococcus aureus confirmed by the synovial fluid culture. The reasons for our report are to describe the previously unreported appearance of this lesion that was huge lobulated intraspinal and extraspinal mass with infected fluid content originated from the defect of the pars interarticularis.
