BACKGROUND: Respiratory depression with high dose of propofol during induction is one of the major complications. We studied the effects of midazolam as premedicant on frequency and duration of apnea and frequency of loss of consciousness in relation to single dose of propofol. METHODS: We selected 194 adult patients who had clear consciousness and no depression of respiration. We allocated patients randomly to control group and midazolam group. In midazolam group, we injected 0.06mg/kg of midazolam intravenously 10min before induction, and in control group, we did nothing. Under mask oxygenation with 100% oxygen, we administered a bolus of propofol (1, 1.5, 2 mg/kg to subgroup 1, 2, 3 respectively) intravenously. The change of respiration and loss of consciousness were observed. RESULTS: The frequency and duration of apnea increased with the dose of propofol in both control and midazolam group. But there were no difference between groups except frequency of apnea with 1.5 mg/kg of propofol. In control group, frequency of loss of consciousness increased with the increasing dose of propofol. But in midazolam group, nearly all the patients was slept without difference by the dose. CONCLUSIONS: Premedication with midazolam reduce the sleeping dose of propofol to induce anesthesia, so the frequency and duration of apnea which is caused by high dose of propofol can be decreased.

We report a case of cutaneous T-cell lymphoma in a 40-year-old man. He has suffered from generalized pruritus for 10 years. Seven months ago, multiple nodules developed over the scalp, face, and thigh. The physical examination showed thickened dystrophic twenty nails with brownish discoloration and lichenified, eczematoid lesions over the trunk and extremities. The skin biopsy revealed diffuse, extensive infiltrates of atypical lymphoid cells in the dermis, which appeared as T lymphocytes by immuno-histochemistry; approximately 90% of the tumor cells were CD3-positive, 80% were CD4-positive, and 60% CD45RO-positive. Laboratory analyses in the peripheral bload showed 18% atypical lymphocytes (Sezary cell), an elevated LDH(746 U/liter), and abnormal lymphocyte subset proportions(ratio of Th/Ts is 4.08). A bone marrow puncture revealed the infiltrations of lymphoid cells and computed tamo-graphy showed no evidence of other organ involvement except the swelling of bilateral inguinal lymph nodes. Spontaneous partial regression of the tumors ensued on the way of oral antihistamines and topical corticosteroids for the relief of the pruritus. The tumorous skin lesions and onychodystrophy disappeared completely with 6 cycles of systemic chemotherapy of CHOP(cyclophosphamide, doxoru-bicin, vincristine, and prednisone).

Chronic dermatological problems associated with lower limb amputation sites include local maceration, intertrigo, blistering and ulceration, contact dermatitis, tissue atrophy, verrucous hyperplasia, lichenification, callosities, epidermoid cyst formation, and malignant neoplasia. A 60 year-old male was presented with a verrucous oozing eruption of the amputation stump of the left leg. He had been involved in a railroad logging accident 30 years before, resulting in the loss of the left lower limb. He were a below-knee prosthesis (patellar-tendon hearing). We diagnosed him as verrucous hyperplasia by clinical and histological findings and then referred him to the division of rehabilitation for a refitting of his prosthesis, after which his eruption cleared two months later.

To study the relationship between the bone mineral density measured by DEXA and QCT methods and to study the factors influencing on the value, bone mineral density in 208 patients with low back pain were measured by the two methods and compared statistically. Ages were varied between 17 to 79(Av. 46.7) years and male and female were 86 and 122. The results of this are as follows; 1. The values of DEXA and QCT showed statistically significant relationship(γ=0.58) as a whole. And bone mineral density in L2, L3 and L4 showed no difference in both groups. 2. Bone loss by aging(per year) in male and female was 0.99% and 1.06% by DEXA, 0,99% and 1.41% by QCT. 3. Body height and weight showed no significant influence of the value in two methods. 4. In body mass index over 27.5, the value measured by QCT was influenced to be diminished while that of DEXA was not influenced. 5. The value by QCT was influenced to be diminished by the increase of age especially over 50 years old in both sex. While the value by DEXA was influenced to be lowered than expected in female over 50 years old. It is concluded that the methods of measurement of bone mineral density have their limitation depend on the age, sex and mass index.

PURPOSE: To clarify the chracteristic sonographic features of benign soft tissue tumors and to evaluate the usefulness of sonographic imaging. MATERIALS AND METHODS: We retrospectively reviewed ultrasonographic images of 70 cases in 68 patients with histologically proved benign soft tissue tumors. RESULTS: The tumors included 33 lipomas, 11 hemangiomas. 11 lymphangiomas, 7 neurilemmomas, 4 epidermold cysts, 2 fibromas, 1 mesenchymoma, and 1 myxoma. The SOhographic appearances of the lesions were mainly solid in 53 cases(33 lipomas, 8 hemangiomas, 2 lymphangiomas, 7 neurilemmomas, 2 fibromas and 1 mesenchymoma), mainly cystic in 14 cases(1 hemangioma, 8 lymphangiomas, 4 epidermoid cysts, and 1 myxoma), and mixed in 3 cases(2 hemangiomas and 1 lymphangioma). Although an accurate histologic prediction could not be made in most cases, certain patterns appeared to be characteristic of specific tumor types. 26 cases(78%) of lipoma were seen as lentiform, iso- or hyperechoic, solid mass. Hemangioma had variable appearance and chacteristic calcifications were seen in 3 cases. Unicameral or multiseptated cystic mass with variable thickness of echogenic septa and solid portion was the characteristic finding of lymphangioma. Neurilemmoma showed Iobulated, oval to round, relatively hypoechoic mass with or without internal cystic portion. CONCLUSION: Sonographic evaluation of benign soft tissue tumros is useful in demonstrating the location, size, extent, and internal characteristics of the mass. A relatively confident diagnosis can be made when the characteristic features of the benign soft tissue tumor are present on sonographic imaging.

The authors reviewed the clinical findings and treatment results of 12 cases of spinal meningeal cysts which were detected in MRI of low back patients. In these lesions, large cysts without CSF communication can compressed the nerve roots within spinal canal and it is difficult to confirm the cause of symptom whether it is originated from cysts or from associated spinal disorders. The terms and classifications of spinal meningeal cysts were very confusing. Among 12 cases, we excised 3 cases of large cysts with gluteal and perianal pains that were caused by compressed sacral nerve roots. All three cases were type 2 cyst (classified by Nabors) and located in sacral canal. In one case associated with isthmic spondylolisthesis, posterolateral fusion and pedicle screw fixations were combined with cyst excision. In other two cases, there were not any spinal pathologic findings that compressed sacral nerve roots except mild degenerative changes and intervertebral disc herniation in lower lumbar and sacral levels All 3 excised cases showed good prognosis in more than one year follow up. The other cases were treated conservatively for the associated spinal disorders.
