Heterotopic ossification(HO) is a frequent complication of total hip arthroplasty(THA), If it is sevre enough, it can convert a successful result of the operation into a poor one. Among several strategies that researches in recent years have tested, radiation therapy have been accepted to have efficacy for prevention of heterotopic ossification by many authors. While postoperative irradiation has been shown to lower the incidence of HO effectively in high risk patients following THA, patients in multiple dose protocols continue to develop some heterotopic ossifiction despite therapy and have some problems. Ninteen patients received single dose exposure to 600 rad delivered within 48 hours of THA with shielding of prosthesis region. The patients were considered high risk group for developing HO because of hypertropic osteoarthritis, post-traumatic osteoarthritis or the presence of previous formed ectopic bone. The average follow up period was 10.2 months(range 6 months

It has long been an accepted policy to employ radiation therapy as initial treatement of choice for most casesof invasive carcinoma of cervix uteri. But, complications following radiotherapy were troublesome problem fot thepatients cured by radiation therapy. The aim of the present study is to present the types and rate of complicationsand to evalute the contributing facors induced the radiation complications. The aim of the present study is topresent the types and rate of complications and to evalute the contributing factors induced the radiationcomplications. 957 cases of invasive carcinoma of cervix uteri receiving radiation therapy were analyzed. Theconclusions are as follows; 1. Bowel complications developed in 96 cases (10.03%). 2. 86% of all bowelcomplications appeared during the first 18 months and most frequently seen after 6 to 12 months(40.03%). 3. Thefrequency of complicaiton was higher in older age and larger irradiation dose, but there is no apparentcorrelation between stage and the occurrence of complications. 4. Portal combination was also a contributingfactor. Highest frequency was noted in AP & PA parallel opposing portals followed by 4 oblique portals and boxtechnique.

A retrospective analysis of survival data of 52 cases with brain astrocytomas was presented. All patients received post-perative radiotherapy in the period of 1973~1983 at YUMC, Yonsei Cancer Center. There were 24 patients with Grade II, 12 patients with Grade III and 16 patients with Grade IV astrocytomas. Survival rates were analyzed according to histologic grade of malignancy, age, tumor location. radiation dose and extent of surgical tumor resection. 5 year actuarial survival for patients with Grade II astrocytomas was 32.9% ad Grade III was 42.9%. The 1 year and 2 year survival rate of Grade IV astrocytomas were 46.7% and 0%. Histologic grade of tumor was important prognostic factor in brain astrocytomas. Age and extent of surgical resection were significant prognostic factors in all grades of astrocytomas and tumor location and radiation dose were significant in Grade II astrocytomas.

PURPOSE: This study aimed to compare differences on sexual satisfaction between non-smokers and smokers of Korean adult males. METHOD: The subjects of this study were 304 current smokers and 331 current non-smokers(stop smokers, never smokers) (58.0%). Because of the nature of the study, the participants were recruited through a home page advertisement of a brand newspaper company in Korea, and the survey was done through Internet system. The tool to measure participant's sexual satisfaction was adopted from the Arizona Sexual Experience Scale-Male. RESULT: Participant's age ranged from 20 to 49, mostly in their 30s-40s(96.1%). They were smoking average of 15 cigarettes per day. There were no significant difference on sexual satisfaction between current smokers and non- smokers(t=-.55, p>.05). However, there were significant difference on sexual satisfaction between ever smokers(n=481) and never smokers(n=154) (t=2.10, p<.05). There were significant differences an erectile and orgasm satisfaction according to number of cigarettes they smoked per day. 54.5% smokers who said that they have difficulty in keeping erectile state considered on smoking cessation within 30 days whereas 24.2% in those who said that keeping erectile state was easy. CONCLUSION: Informing about the high risk of sexual dysfunction with cigarette smoking should become a important part of smoking cessation education and for smoking adolescents.

Radiation plays an important role in the management of breast cancer. The role of radiotherapy in the management of breast cancer can be defined in four categories as follows : (1) primary radiotherapy in breast-conserving treatment(BCT) for early breast cancer including ductal carcinoma in situ(DCIS). (2) Adjuvant radiotherapy after mastectomy for high-risk patients. (3) Radiotherapy with or without surgery after neo-adjuvant chemotherapy in locally advanced breast cancers. (4) Palliative radiotherapy for metastatic disease, mostly bone and brain metastases, and locoregional recurrences. Recently, the application of radiotherapy in the management of breast is increasing. The increased use of mammographic screening have dramatically increased the percentage of cases of breast cancer diagnosed at noninvasive or early stages of disease. As BCT has become the standard treatment for woman with DCIS and a preferred treatment method for early invasive cancers, the proportion of patients who need a radiotherapy is increasing. Also, post-mastectomy radiotherapy(PMRT) is re-appraised because some studies proved that PMRT not only decreased local recurrence but also improved survival rate. Many patients live for decades after treatment. Therefore, technical excellence in irradiating the intact breast or chest wall is very important to reduce long-term complications as well as to control the disease. Rationale, indications, and technical aspects of primary radiotherapy in breast-conserving therapy for early breast cancer and PMRT for operable breast cancer wareas reviewed.
