Although sacrococcygeal mass is rare and usually found in infants or children, adolescent or adult patients with protruding mass in sacrococcygeal region occasionally come to us simply for a cosmetic problem. In this situation, even though there is no definite neurological deficit, it should be evaluated whether or not the underlying bony pathology or dural defect exists. Few cases about the sacrococcygeal mass have been reported in adults. We reviewed our cases including preoperative evaluation methods and postoperative diagnosis. From March, 1993 to February, 1997, we experienced 6 adult patients with sacrococcygeal mass and no neurological abnormality. Preoperative evaluation were made by plain X-ray, myelogram, computed tomography(CT), and magnetic resonance imaging (MRI), as needed. Postoperative diagnoses were 2 meningoceles, 2 lipomyelomeningoceles, 1 desmoid tumor, and 1 teratoma. From our experiences, CT or MRI is essential to evaluate the sacrococcygeal mass preoperatively. These methods can visualize the precise anatomic location and extent of the mass, its relation to the spinal cord, and associated bony abnormalities. MRI is superior to CT, especially in defining the nature of the mass and involvement of the spinal cord. Conclusively, even a simple mass in the sacrococcygeal region in adults needs MRI or CT evaluation, and MRI is the most valuable method of evaluating the mass preoperatively and provides important information to establish a treatment plan.

Total cholesterol and triglyceride were measured in sera of 40 cases of hypertension, 22 cases of myocardial infarction, 14 cases of cerebral thrombosis, 18 cases of subarachnoidal hemorrhage and 30 cases of normal control in Chungnam national University Hospital from October 1980 to September 1981, and the results are as follows; 1) The mean serum total cholesterol and triglyceride levels in normal control group are 153.57+/-40.60mg% and 150.82+/-51.76mg%. 2) The age incidence of these diseases were highest in 6th decade. 3) Serum cholesterol levels of myocardial infarction, hypertension, cerebral thrombosis and subarachinoidal hemorrhage group were higher than that of normal control group. 4) Serum triglyceride levels of acute myocardial infarction and hypertension were significantly higher than that of normal control group, but there is only slightly increases in cerebral thrombosis and subarachinoidal hemorrhage. 5) In general, serum lipid levels are higher in cardiovascular diseases(hypertension and myocardial infarction) than cerebrovascular diseases(cerebral thrombosis and subarachnoidal hemorrhage). 6) Serum Cholesterol and triglyceride levels decreased by administration of pancreatic mucopolysacharide for 1 or 2 months. In conclusion, it seems that high serum cholesterol and triglyceride level may play and important risk factor in development of hypertension and myocardial infarction.

BACKGROUND: Procaine binds to DNA and reduces cisplatin nephrotoxicity, but the mechanism is poorly understood. We explored whether procaine amelioration of cisplatin nephrotoxicity was related to down-and/or up-regulation of inflammatory response gene tumor necrosis factor-alpha (TNF-alpha), oxidative stress indicator gene heme oxygenase-1 (HO-1) or cell cycle inhibitor gene p21. METHODS: Cisplatin and procaine were intraperitoneally injected to mice at a single dosage of 16 and 80 mg/kg, respectively. Renal evaluation was performed 72 hours after cisplatin administration. The expression of transcripts and proteins was analyzed using real time RT-PCR and Western blot, respectively. RESULTS: Procaine treatment moderately attenuated necrotic changes of renal proximal tubules and increases in BUN and creatinine concentration by cisplatin administration. Kidney platinum level between the cisplatin (cis) group and the cisplatin + procaine (CisPro) group was not different. Although the level of TNF-alpha mRNA increased 4-fold higher in the Cis group than in the control, this increase was not attenuated by procaine treatment. Gene expression of p21 and HO-1 was elevated 175 and 4-times higher in the Cis group than in the control, respectively. But their expression was no further elevated, rather significantly reduced in the CisPro group compared to the Cis group. Protein abundance of p21 and HO-1 was paralleled by their respective mRNA expression. CONCLUSIONS: Procaine amelioration of cisplatin nephrotoxicity is likely to be achieved through processes other than the regulation of TNF-alpha, HO-1 or p21 gene expression.

BACKGROUND: This study was performed to investigate the clinical usefulness of acute normovolemic hemodilution to reduce homologous transfusion in revision total hip arthroplasty. To avoid complications of homologous transfusion, many methods are being used in patients who undergo an operation, and autologous transfusion is the most popular modality. METHODS: Fifty-five patients operated on for revision THRA were reviewed. In the hemodilution group (n = 21), 2-4 units of autologous blood were procured immediately after anesthetic induction while Ringer's lactate and 6% Haes-steril were infused to maintain normovolemia. Differences in the amounts of transfusions and postoperative drainage were compared. Statistical analyses were performed by using the Student's t-test. RESULTS: No significant differences were observed between groups in terms of preoperative hematocrit and hematocrit at postoperative 7 days. However, in the homologous transfusion group, 10.1 +/- 3.2 units of RBC products were used in 34 patients. In the autologous transfusion group, 7.5 +/- 2.6 units of RBC products were transfused in 21 patients. And this difference in RBC produce usage was significantly different (P < 0.05). The amount of postoperative wound drainage in the two groups was comparable. CONCLUSIONS: ANH could reduce the reqirement for homologous transfusion in revision total hip arthroplasty.

With the steady rise of health and environmental awareness, the number of bicyclists is increasing. However, there are few epidemiologic studies on bicycling under the influence (BUI). The aim of this study was to determine the prevalence of BUI and the associated risk factors in a representative Korean population. The data of 4,833 adult bicyclists who participated in the Korean National Health and Nutrition Examination Survey (2010–2012) were analyzed. Among the 4,833 participants investigated in this study, 586 (12.1%) had experienced BUI. As participants’ age increased, so did the prevalence of BUI (P < 0.001), with the participants who were aged 60–69 showing the highest prevalence of BUI (19.6%). With regard to BUI and drinking habits, the likelihood of being a heavy or high-risk drinker increased with the frequency of BUI (P < 0.001). In addition, there was a positive relationship between the frequency of BUI and alcohol use disorder identification score level. Finally, those who had previous experiences of BUI were significantly more likely to drive and ride motorcycles under the influence (P < 0.001). In conclusion, the prevalence of BUI was 12.1% and several associated risk factors for BUI were elucidated in this study. The development of specific preventive strategies and educational programs aimed at deterring individuals at a high risk of engaging in BUI is expected to reduce the number of alcohol-related bicycle injuries.

PURPOSE: To evaluate the histopathological prognostic factors, relapse pattern and survival in patients with endometrial carcinoma who were treated with surgery and postoperative adjuvant radiotherapy (RT). METHODS AND MATERIALS: From September 1991 to December 1997, 27 patients with endometrial carcinoma treated with surgery and postoperative adjuvant RT at Asan Medical Center were entered in this study. Surgery was performed with total abdominal hysterectomy in six, total abdominal hysterectomy with pelvic lymph node dissection in eight and radical hysterectomy in 13 patients. External RT of 50.4 Gy was done to all patients and among these, additional high dose rate vaginal vault irradiation of 20-25 Gy with fractional dose of 4-5 Gy was boosted in 16 patients. The patients were followed for 6-95 months (median 30). RESULTS: The number of patients according to FIGO stage were I 18 (67%), II 1 (4%) and III 7 (26%). Patients with poor histologic grade, deep myometrial invasion, adnexal involvement, lymphovascular invasion showed more pelvic lymph node involvement, but no statistical significance was indicated. The 5year overall and disease free survival were 100% and 76.8%, respectively. Relapse sites were pelvic, para-aortic lymph node, and multiple metastases including lung, and no vaginal relapse was developed. Factors that were associated with disease free survival were FIGO stage (p=0.01), lymphovascular invasion (p=0.03), pelvic lymph node involvement (p=0.000 1). There was only one Grade 1 rectal bleeding without moderate to severe complications. CONCLUSION: Postoperative adjuvant RT is considered to reduce the loco-regional failure, resulting the improvement of survival. The group of patients with the risk of vaginal failure without vaginal vault irradiation should be investigated according to stage and grade.

PURPOSE: To evaluate the side effects, pattern of failure, and survival rate according to the sequence of postoperative adjuvant radiotherapy and chemotherapy, patients with stages II and lll rectal cancer who had undergone curative resection were randomized to early radiotherapy group (arm I) or 'late radiotherapy group (arm II)', then we intend to determine the most effective sequence of the radiotherapy and chemotherapy. MATERIALS AND METHODS: From January 1996 to March 1999, 3 13 patients with curatively resected stages II and III rectal cancer have been randomized to early' or late radiation therapy group and recei ved combined chemotherapy (5-FU 375 mg/m/day, leucovorin 20 mg/m, IV bolus daily D1-5, 8 cycles) and radiation therapy (whole pelvis with 45 Gy/25 fractions/5 weeks). Arm I received radiation therapy from day 1 with first cycle of chemotherapy and arm II received radiation therapy from day 57 with third cycle of chemotherapy after completion of first two cycles. Preliminary analysis was performed with 228 patients registered up to Jun 1998. Two out of the 228 patients were excluded because of double primary cancer. Median follow-up period was 23 months. RESULTS: Local recurrence occurred in 11 patients (9.7%) for arm I and 9 patients (8%) for arm II. There was no significant difference between both groups (p=0.64). However, distant metastasis was found in 22 patients (19.5%) for arm I and 35 patients (31.0%) for arm II and which showed statistically significant difference between the two groups (p=0.046). And neither 3-year disease-free survival (70.2% vs 59.2%, p=0.2) nor overall survival (89.4% vs 88.0%, p=0.47) showed significant differences. The incidence of leukopenia during radiation therapy and chemotherapy was 78.3% and 79.9% respectively but leukopenia more than RTOG grade 3 was only 2.1% and 6.0% respectively. The incidence of diarrhea more than 10 times per day was significantly higher in the patients for arm I than for arm II (71.2% vs 4 1.6%, p=0.02) but this complication was controlled with supportive cares. CONCLUSION: Regardless of the sequence of postoperative adjuvant radiation therapy and chemotherapy a fter curative resection for rectal cancer, local recurrence rate was low with combined chemoradiotherapy. But distant metastasis rate was lower in early radiation therapy group than in late radiation therapy group and the reason is unclear. Most patients completed these treatments without severe complication, so these were thought to be safe treatments but the treatment compliance should be improved.

PURPOSE: evaluate the effectiveness of minimally invasive plate osteosynthesis (MIPO) in unstable fractures of the distal tibia. MATERIALS AND METHODS: From March 2001 to December 2003, 21 cases with unstable fractures of the distal tibia were treated with MIPO technique and followed for at least one year. Eighteen cases were extra-articular and three cases were intra-articular fractures. According to AO classification, six cases were 42-A, four 42-B, one 42-C, seven 43-A, and three 43-C. There was only one case of Gustilo-Anderson type II open fracture. We reviewed the results of fracture healing, axial and rotational deformity, ankle motion, and complications RESULTS: All fractures were healed in an average of 16.1 weeks (range, 11 to 24 weeks). There was only one case of 7-degree posterior angular deformity, but no cases of rotational malalignment. Recovery of ankle motion was satisfactory in all patients within 5-degree loss of motion. Subcutaneous abscess was developed in one case after fracture healing and cured by a drainage with implant removal. CONCLUSION: Although MIPO technique is technically more demanding than the traditional open technique, MIPO technique is an effective method for unstable fractures of the distal tibia because it minimizes incidence of soft-tissue compromise and infection and provides good fracture healing.
