Mayer-Rokitansky-Kuster-Hauser Syndrom is characterized by the absence of the vagina and the uterus, the presence of apparently normal tubes and ovaries, feminine appearance, normal female secondary sexual characteristics, a normal 46, XX karyotypes, and a feminine psychosexual orientation. Absence of the vagina results from an embryological arrest in the development of the lower portion of the Mullerian system. Various methods of surgical treatment for the vaginal absence in this syndrom have been introduced but the ideal method to restore the original dimension and function of the normal vagina was not found. The two cases reviewed in this paper were all treated with modified McIndoe operation using full thickness skin grafts. Postoperatively both women were satisfied without complications, i,e. lack of skin graft, bleeding, urethrovaginal fistula, perforation of the rectum, rectovaginal fistula and significant vaginal stricture. This paper reveals the satisfactory results that were uniformly good.

A case of myxoma of the breast was reported. A 25-year-old woman showed a lump in the left breast which was suddenly enlarged after the delivery of a baby. A tumor measuring 73.53cm was located in the upper outer quadrant of the breast. Fine needle aspiration cytology revealed scattered benign spindle shaped mesenchymal cells with abundant myxoid material. On excision, the tumor was partly solid, partly cystic and multilocular. Each nodule consisted of an abundant mucoid material with a few spindle or stellate mesenchymal cells. Pleomorphism and mitosis were absent. The mesenchymal cells showed immunoreactivities for S-100 protein, smooth muscle actin, and CD34. The myxoid stroma was positively stained with alcian blue and mucicarmine. These findings suggest that constituent cells derive from totipotential primitive mesenchymal cells.

Injuries and pains of musculoskeletal joint in human body is common onset in industrialized world. However, muscle fatigue plays a very significant role in contributing causes of many pains associated with musculoskeletal joints. Based on this hypothesis, degree of muscle fatigue was investigated using electromyography measurement technique during isometric and concentric/eccentric muscle contractions. Different response of the muscle fatigue between two different muscle contractions (isometric and concentric/eccentric contractions) was examined by comparison of parameters which were median frequency, median power and RMS value. Healthy 16 young persons without previous musculoskeletal diesease history were tested with Noraxon Myosystem 2000 EMG measurement system. In this study, two different exercises were performed. First exercise was concentric/eccentric exercise. Second exercise was isometric muscle contraction. In the case of the isometric exercise, median frequency was decreased, but median power and RMS were increased. However, during the concentric/eccentric exercse, median frequency was increased, but median power and RMS were decreased. Both of those revealed that the pattern of the median frequency was W type, but median power and RMS were M type as time passed. In this study, the patterns of the muscle fatigue during concentric/eccentric exercise as well as isometric exercise were identified. It will be helpful to prevent musculoskeletal injury from over-working andexercising.

There are some effective methods for removing layers of skin to improve aging face and dermatologic defects : chemabrasion (chemical peeling), dermabrasion(surgical removal), laserabrasion. Chemabrasion, generally performed with a chemical solution, is most useful for removal of fine facial wrinkles and abnormal pigmentation. The application of chemical caustics, especially TCA (trichloroacetic acid), is known to be an effective and is now commonly practiced to improve the surface of the facial skin that has been blemished by pigmentation, wrinkles, solar damage and certain scars. Trichloroacetic acid is a colorless melting crystal and derivatives of acetic acid which das protein precipitating properties. It has specific odor but there is not systemic toxic effect like a phenol. It has heavy caustic effect on skin and mucosa and cause the coagulation necrosis of the skin and therefore, it must be handled carefully and stored in the proper condition. Especially, moderate to high concentrated TCA solution must be treated by well-trained persons. A 46-year-old woman visited a private clinic for removal of fine wrinkles around the lip. She was refered to our department because of acute upper lip coagulation necrosis which was caused by injection of 35% TCA solution mistaken for lidocaine, which was supposed to be used for anesthesia. At her arrival, cental half of upper lip showed severe coagulation necrosis. The lesion was well discriminated in a few days, then debridement and immediate reconstruction was done using an Abbe flap. Chemical peeling is a relatively effective procedure for improvement of aging skin lesion in a lower cost with a short time operation, if the practitioner has much experience and optimal indication is properly selected. But not so as, side effect and complication may be often ocurred in a mistake and as a result irreversible scars are remained. We experienced a rare case of upper lip necrosis which was caused by TCA injection mistaked for lidocaine in a private clinic and so, We report this case with the results of experiment of rabbit model which was observation of macroscopic and microscopic changes of the abdominal skin of the rabbit injected with serially diluted TCA solution.

Four cases of newborn with tension pneumothorax induced by a conventional ventilator were admitted to our nursery from January 1. 1992 to June 30. 1992 and they were managed by high frequency ventilator (Infrasonic Infant Star Ventilator). In contrast, four cases of newborn with tension pneumothorax who were continuously on the conventional ventilator, were included as a control group. They were admitted to our nursery from July 1. 1991 to december 31. 1991 and they were managed by conventional ventilator with conservative treatment. 1) In the control group, who were continuously managed by the conventional ventilator after thoracostomy with water seal drainage, we changed ventilator setting appropriately in control group but they had poor arterial blood gas analysis. The arterial blood gas analysis within 24hr/within 72hr in control group were pH 7.192/7.195, Paco2 72.15/82.25, PaO2 78.92/83.875, HCO3-26.975/27.925 and conventional ventilator care did not show any definite benefit for improvement of arterial blood gas analysis and tension pneumothorax as well. 2) Two cases in control group expired on the 6th day of thoracostomy without any resolution of tension pneumothorax. 3) In contrast, four cases with tension pneumothorax managed by high frequency ventilator were improved. Tension pneumothorax and arterial blood gas analysis to normalize from 6hr of high frequency ventilation and four cases of tension pneumothorax were completely reabsorbed within 4days.

An epidemiological study on brugian filariasis was carried out in endemic areas including Cheju Island in Korea, with a brief review of literatures.The results showed that the incidence among residents has remarkably decreased in Cheju Island, which was the main endemic area. Reviewing available informations on the prevalence of filariasis reported in recent years and also judging from the present socio-economic conditions which enable people to practice personal protection against mosquitos, it can be said with confidence that filariasis has almost disappeared from Cheju Island and inland areas. The disease is considered to remain at a low level of endemicity in Hugsan Islands. Certainly mass diethylcarbamazine (DEC) treatment carried out in Cheju Island in the 1960s and 1970s and remarkable economic growth followed by improved living standard and altered life-style of inhabitants could all have combined effects on the disappearance of this mosquito-borne diseae in this island. If the present trends go on, the possibility of resurgence of filariasis in Cheju Island is hardly postulated.
