The authors examined 9 condylomas, 26 cervical intraepithelial neoplasms(CIN) and 22 invasive squamous cell carcinomas for the presence of human papillomavirus(HPV) DNA sequences by DNA-DNA in situ hybridization. In situ hybridization revealed target HPV DNA sequences mostly in the nuclei of the superficial cells from epithelium which contained either maturation or koilocytotic atypias. With the use of biotinylated HPV DNA probes 6/11, 16/18 and 31/33/35, 42 of the 57(73.7%) were positive with HPV-6/11, 23 with HPV-16/18, 32 with HPV-31/33/35 and 18 with two or more mixed probes. HPV-31/33/35 was wht most prevalent in CIN and invasive squamous cell carcinomas, follwed by HPV-16/18. The incidence of HPV DNA increased from 66.7% to 86.4% with increasing severity of the lesions from condylomas to invasive squamous cell carcinomas. Flat condyloma was most freuently accompanied by CIN.

Tensiomyography (TMG) is known as non-invasive method which assesses the muscular characteristics such as contraction velocity or maximal displacement of the belly. The aim of this study was to evaluate muscular responses by TMG after muscle injury and to introduce using TMG first in Korea. This study was performed with a subject who was diagnosed with muscular injury and consent measuring and following up TMG analyses. A female patient, who was diagnosed left hip adductor muscle strain, underwent magnetic resonance imaging (MRI) and TMG at intervals of two weeks. We obtained decreased in displace maximum (Dm, 4.14 vs. 5.69) and altered curve shape in the injured muscle at the initial TMG assessment in comparison to the non-injured side. After two weeks, MRI findings and symptom were improved and Dm in the injured side increased as in the non-injured muscle. These findings suggest that a decrease in Dm indicate increased in muscle stiffness after muscle injury, and an increase in Dm as in the non-injured side after two weeks indicate recovered status. TMG may be useful as a simple and non-invasive device for monitoring muscle function after muscle injury and during the recovery.

Recurrence in patients with superficial bladder tumor is a serious problem. In one series, the recurrence rate was 73%, and invasive cancer developed in 10% of patients with recurrences. To eliminate or reduce the rate of recurrence, topical chemotherapy has been tried and showed adjunct effects. We studied to evaluate prophylactic effects of topical chemotherapy in 51 patients with superficial bladder tumor admitted to the Department of Urology, Kyung Hee University Hospital during the period from April, 1979 to April, 1984. Patients were divided into 2 groups. Group A comprised 19 patients (Adriamycin; 8, Thio-TEPA; 11) treated with topical chemotherapy following initial TUR and 27 patients treated by TUR only. Group B comprised 5 patients treated with topical chemotherapy (Adriamycin) after repeated TUR and 7 patients among 27 patients who had repeated TUR for recurrence. Patients treated by TUR only were defined as control group. Recurrence rate was analyzed in each group. Following results were obtained. 1. In group A, recurrence rate was 2.54 in patients with chemotherapy comparing to 3.35 in control patients. Average interval of recurrence was 39.3 months in chemotherapy patients and 29.8 months in control patients. 2. In group B, recurrence rate was higher in chemotherapy patients than in control patients with rate of 6.6 and 5.3, respectively. But recurrence rate was diminished to 6.6 after chemotherapy comparing to pre-chemotherapy period (10.3). 3. There was no difference in recurrence rate relating to multiplicity of tumor as a whole.

BACKGROUND: There are cases in which shoulder pain persists long after shoulder joint surgery and this pain can not be reduced by intravenous patient controlled analgesia (IVPCA). Our purpose was to evaluate the effect of stellate ganglion block (SGB) on postoperative shoulder pain and also to investigate the effect of preventive SBG on complex regional pain syndrome (CRPS). METHODS: Forty patients, who were evaluated to ASA class 1 and 2 and who were scheduled for shoulder joint surgery under general anesthesia, were randomly divided into 2 groups. The experimental group of patients (n = 20) received SGB with 0.5% mepivacaine 8 ml after induction of general anesthesia. The control group of patients (n = 20) received only general anesthesia. Their postoperative pain was assessed using the visual analog scale (VAS) at 30 min, 1, 2, 6, 12, 24 and 48 hours postoperatively. Whenever patients wanted supplemental analgesia, diclofenac sodium 75 mg was injected intramuscularly and the need for supplemental analgesia was recorded. RESULTS: The experimental group of patients had significantly lower pain scores at 30 min, 1, 2 and 6 hours and also significantly lower analgesic requirement at 1, 2 and 6 hours. CONCLUSIONS: We found SGB was effective for controlling postoperative pain after shoulder joint surgery. Also, we could expect that SGB reduced the incidence of CRPS.

PURPOSE: To evaluate the treatment outcome and prognostic factor of postoperative radiotherapy for extremity soft tissue sarcoma (STS). MATERIALS AND METHODS: Forty three patients with extremity STS were treated with conservative surgery and postoperative radiotherapy from January 1981 to December 2010 at Korea University Medical Center. Median total 60 Gy (range, 50 to 74.4 Gy) of radiation was delivered and 7 patients were treated with chemotherapy. RESULTS: The median follow-up period was 70 months (range, 5 to 302 months). Twelve patients (27.9%) sustained relapse of their disease. Local recurrence occurred in 3 patients (7.0%) and distant metastases developed in 10 patients (23.3%). The 5-year overall survival (OS) was 69.2% and disease free survival was 67.9%. The 5-year local relapse-free survival was 90.7% and distant relapse-free survival was 73.3%. On univariate analysis, no significant prognostic factors were associated with development of local recurrence. Histologic grade (p = 0.005) and stage (p = 0.02) influenced the development of distant metastases. Histologic grade was unique significant prognostic factor for the OS on univariate and multivariate analysis. Severe acute treatment-related complications, Common Terminology Criteria for Adverse Events (CTCAE) grade 3 or 4, developed in 6 patients (14.0%) and severe late complications in 2 patients (4.7%). CONCLUSION: Conservative surgery with postoperative radiotherapy achieved a satisfactory rate of local control with acceptable complication rate in extremity STS. Most failures were distant metastases that correlate with tumor grade and stage. The majority of local recurrences developed within the field. Selective dose escalation of radiotherapy or development of effective systemic treatment might be considered.

Torsade de pointes is a life-threatening, polymorphic ventricular tachycardia associated with prolongation of the QTc interval. Although torsade de pointes is found in many clinical settings, it is mostly drug induced. Similar problems have been described with nonsedating H1-selective antihistamines like terfenadine and astemizole. The increased risks of both H1-antihistamines were associated with exposure to supratherapeutic doses or concomitant exposure to the cytochrome P-450 inhibitors, ketoconazole, erythromycin and cimetidine. We report a 51-year-old woman with torsade de pointes and a long QTc interval caused by the combined use of terfenadine and itraconazole. After discontinuation of these drugs and treatments with electrical cardioversion and magnesium sulfate, torsade de pointes and prolonged QTc interval were no longer observed and she was discharged in good condition with a normal ECG. In conclusion, physicians should be aware that terfenadine and astemizole can cause torsade de pointes in rare cases.

Amputation of penis occurs most commonly as an act of self-emasculation. Fortunately, complete amputation of penis is quite rare but potentially devastating occurrence. Reimplantation of the penis has both cosmetic and functional objectives. Recently, several successful applications of microvascular technique to reimplantation of the amputated penis have been reported. Also herein, we present a case of successful reimplantation of completely amputated penis by using a microvascular repair.

PURPOSE: This study is designed to evaluate the reliability for studies of tensiomyography (TMG). TMG can evaluate muscle function noninvasively and selectively. METHODS: We measured 12 male volunteers (age, 26.5±7.6 years; height, 175.3±4.7 cm; weight, 78.8±13.3 kg) in this study and measured TMG during three occasions over 3 consecutive days. None of the participants has had any history of neuromuscular disorders or muscle diseases. Vastus lateralis, vastus medialis (VM), rectus femoris (RF) in quadriceps and biceps femoris, semitendinosus in hamstrings muscles were measured. Coefficient of variation (CV%) and intraclass correlation coefficient (ICC) have been calculated about maximal displacement (Dm, mm) and contraction time (Tc, ms) which are main parameters. RESULTS: Most of the ICC of Dm were over 0.8 and the highest among the muscles except both VM. And, most ICC of Tc was lower than Dm except both BF (right, 18.31; left, 15.03). But, the ICC of Tc was lower than Dm except left RF (0.890) and VM (0.859). CONCLUSION: This study has shown that the Dm is high levels of the ICC and CV(%) in thigh muscle except VM. In the future, we plan to establish the method of measurement more clearly for reducing the errors of measurements. The technique of correct palpation of measurable muscles using TMG devices is also necessary.
