Hamartoma of the breast is relatively rare benign tumor, which is a well-circumscribed mass mainly composed of fibrous stroma, a(tipose tissue, ducts and acini. Muscular hamartoma of the breast is mainly composed of smooth muscle, and is extremely rare because proper smooth muscle is normaly absent in the breast except in the nipple. We describe a rare case of muscular hamartoma of the breast in a 38-year-old woman. This tumor was located in the upper outer quadrant and a 3 x 2.5 x 2 cm sized, well-demarcated but not encapsulated mass, The mass consisted mainly of irregularly arranged smooth muscle bundles in the fibrous stroma with lobular units and admixed fat cells. The origin of smooth muscle in hamartoma is not well known.

The short term beneficial effect of arthroscopic excision of synovial tissue in knees with rheumatoid arthritis have been well documented. The purpose of this study to report the results of synovectomy in patients with rheumatoid arthritis who have been observed at least 3 years. We analysed the clinical result with modified Laurin criteria, radiologic change and patients own satisfaction degree with survey. The results were as follows; 1. The preoperative symptoms were pain (100%), swelling (100%), decreased range of motion (83%) and joint tenderness (74%), and those were improved postoperatively to 43%, 60%, 11%, 43% each other. 2. Among the laboratory parameters, C-reactive protein (CRP) was improved most significantly (pvalue =0.026). 3. On simple supine A-P X-rays, the width of medial joint space and lateral joint space were compared to preoperatively and postoperatively. The width of medial joint space was 4.33mm preoperatively, and it was changed to 3.22mm at last follow up (p=0.032). Those of lateral joint space was changed from 4.24mm preoperatively to 3.27mm at last tollow up (p=0.106). 4. The grade of articular cartilage damage was related with severity of preoperative symptoms and the patients with low grade of articular cartilage damage showed more postoperative improvement. The result of operation was related to symptom duration, degree of X-ray change and degree of cartilage damage. 5. 58% ot patients were satisfied to results of synovectomy, 28% were answered neither satisfied nor ansatisfied and 14% were unsatisf'ied to operation. We concluded the arthroscopic synovectomy of the knee joints was effective procedure to improve the clinical symptoms, range of knee motion and to alleviate the inflammatory reaction at mid-term period al'ter the operation. So we consider this procedure is a palliative treatment that modified and alleviate the progression of rheumatoid arthritis of knee joints.

Most patients who have spondylolysis dont's need surgical treatment. However, for the patients who have no response to conservative treatment, surgical treatment may be indicated. In 1970, Buck reported the operative technique that the used two screws between the pars defect and lamina followed by bone graft. In patients who have spondyloysis, pain in the back seems to be due to instability and irritation of nerve root by the abnormal motion of the loose neural arch and granulation tissue. For period of 7 years from May, 1984 to March, 1991, twelve patients with spondyloysis who had no response to conservative treatment were treated with Buck's operation and were analyzed. Following results were obtained: 1. The age of the patients was 24 years in average ranging from 14 to 40 years. 2. The level of the lesion was L5 in 10 cases, L4 in 2 cases. 3. Preoperative clinical feature included low back pain in 12 cases, refered pain in 2 cases. 4. Clinical sympotoms were improved in 83%, and the follow up result of the operation: excellent 16.7%, good 66.6% and poor 16.7%.

BACKGROUND: This study aimed to investigate bradycardia as an adverse effect after administration of dexmedetomidine during 33degrees C target temperature management. METHODS: A retrospective study was conducted on patients who underwent 33degrees C target temperature management in the emergency department during a 49-month study period. We collected data including age, sex, weight, diagnosis, bradycardia occurrence, target temperature management duration, sedative drug, and several clinical and laboratory results. We conducted logistic regression for an analysis of factors associated with bradycardia. RESULTS: A total of 68 patients were selected. Among them, 39 (57.4%) showed bradycardia, and 56 (82.4%) were treated with dexmedetomidine. The odds ratio for bradycardia in the carbon monoxide poisoning group compared to the cardiac arrest group and in patients with higher body weight were 7.448 (95% confidence interval [CI] 1.834-30.244, p = 0.005) and 1.058 (95% CI 1.002-1.123, p = 0.044), respectively. In the bradycardia with dexmedetomidine group, the infusion rate of dexmedetomidine was 0.41 +/- 0.15 microg/kg/h. Decisions of charged doctor's were 1) slowing infusion rate and 2) stopping infusion or administering atropine for bradycardia. No cases required cardiac pacing or worsened to asystole. CONCLUSIONS: Despite the frequent occurrence of bradycardia after administration of dexmedetomidine during 33degrees C target temperature management, bradycardia was completely recovered after reducing infusion rate or stopping infusion. However, reducing the infusion rate of dexmedetomidine lower than the standard maintenance dose could be necessary to prevent bradycardia from developing in patients with higher body weight or carbon monoxide poisoning during 33degrees C targeted temperature management.

A 26-year-old female presented herself to our clinic due to noduloulcerative lesions of one month duration on her face and trunk with accompaning headache and mild fever. In family history, her husband was reported to have a history of chaner. On physical examinat.ion, rice sized eythematous papules and bean sized nodules with central ulceration were seen on the face and trunk. VDRL was 1:31 positive. A skin biopsy iif a noduloulcerative lesion showed ulceration, vascular dilatation with fibrinoid changes and perivascular inflarnmatory cellu infilt.rations, especially plasma cells. Immunoperoxidase stain showed T. pallidum at the epidermis and papillary dermis. The diagnsis was made asecondary syphilis with unusual clinical presentation as noduloucerative skin lesions. The skin lesions completely disappeared one month after treatment with injection of benzathine pelnicillin G 2.4 million unit intramuscularly weekly for three times.

PURPOSE: To evaluate the effect of common three photon energies (6-MV, 10-MV, and 15-MV) on intensity-modulated radiation therapy (IMRT) plans to treat prostate cancer patients. MATERIALS AND METHODS: Twenty patients with prostate cancer treated locally to 81.0 Gy were retrospectively studied. 6-MV, 10-MV, and 15-MV IMRT plans for each patient were generated using suitable planning objectives, dose constraints, and 8-field setting. The plans were analyzed in terms of dose-volume histogram for the target coverage, dose conformity, organs at risk (OAR) sparing, and normal tissue integral dose. RESULTS: Regardless of the energies chosen at the plans, the target coverage, conformity, and homogeneity of the plans were similar. However, there was a significant dose increase in rectal wall and femoral heads for 6-MV compared to those for 10-MV and 15-MV. The V20 Gy of rectal wall with 6-MV, 10-MV, and 15-MV were 95.6%, 88.4%, and 89.4% while the mean dose to femoral heads were 31.7, 25.9, and 26.3 Gy, respectively. Integral doses to the normal tissues in higher energy (10-MV and 15-MV) plans were reduced by about 7%. Overall, integral doses in mid and low dose regions in 6-MV plans were increased by up to 13%. CONCLUSION: In this study, 10-MV prostate IMRT plans showed better OAR sparing and less integral doses than the 6-MV. The biological and clinical significance of this finding remains to be determined afterward, considering neutron dose contribution.
