It is known that the toe-flexors exert some power generation in ankle plantar flexion. However, there has been no paper published in which the power generation was quantified. The purpose of this paper, therefore, is to quantify the amount of contribution of the toe-flexors to the ankle plantar-flexion in normal and rapid walking using the kinetic data of three dimensional gait analysis system. In order to restrict the action of the toe-flexors, we designed special braces which can be applied to the forefeet of the examinee during walking. We performed the gait analysis in ten normal adult volunteers with and without braces, and evaluated the moment and power of toe-flexors during terminal stance and pre-swing phase of gait cycle. Gait analysis was done with the VICON 3-dimensional motion analysis system (VICON, Oxford Metrics, Oxford, England) and 2 force plates (AMTI, Advanced Mechanical Technoiogy, Newton, MA, U.S.A,). The kinetic results are as follows: l. Average speeds of normal and rapid walking were 1.12m/sec and 1.41m/sec respectiveIy. 2. In normal walking, peak ankle plantar-tlexion moment decreased 5.5% with braces, and sum of ankle plantar-flexion moment decreased 12.3% with braces. Both of the results were not significant statistically (p>0.05). Peak ankle power generation decreased 11.0% with braces, and sum of ankle power generation decreased 10.4% with braces. These decreases were also insignificant statistically (p>0.05). 3. In rapid walking, peak ankle plantarflexion moment decreased 26.7% with braces. The decrease was horderline significant statistically (p=0.062). The sum of ankle plantar-tlexion moment decreased 26.6% with braces, but the decrease was not significant statistically (p>0.05). Peak ankle power generation decreased 40.2% with braces, and sum of ankle power generation decreased 37.9% with braces. These decreases showed borderline significance statistically (p=0.062). In conclusion, toe-flexors may contribute about 10% of the total ankle plantar-flexion power generation, and the contribution will be increased with increase of walking velocity. We must be very careful to sacrifice the toe-flexors in cases with weak triceps power.

Seborrheic keratosis is a benign epidermal lesion, that commony develops in the aged. It exhibits a remarkable spectrum of histologic variations. We evaluated one hundred and one cases of seborrheic keratoses according to the histologie typing by Lever and Schaurnburg-Lever. The most common histologic type was the acanthotic type(50.5%), and the next. most common one was hyperkeratotic type(33.7%). The rest of the caces were relatively uncommon, irritated type(6.9%), mixed type(4.9%), clonal type(3.9%), adenoidal type(2.0%), and melanoacanthoma(1.0%). In 2 cases, mixed type was found in a lesion.

Primary cutaneous aspergillosis is rare. In this report we describe primary skin infection by Aspergillus in 9 children with leukemia. The skin lesion was characterized clinically by erythematous macule and papule associated with pain and itching, followed by a rapid progression to ulcer and central black eschars with raised erythematous border at the site of venipuncture, insertion of intravenous cannula, or where arm boards had been taped to extremities. Diagnosis was confirmed by skin biopsy and wound culture. Positive revealed in 6 patients, including A. glaucus in 2 cases, A. flavus in 1 case. Treatment consisted of temporary withdrawl of anticancer chemotherapy, intravenous amphotericin B, oral flucytosine, itraconazole and/or rifampin. One patient recovered completely without antifungal medication with resolution of leukopenia. Six of eight treated patients recovered. One patient discharged against medical advice, while cutaneous aspergillosis was improving. One patient died with persistent skin lesion and neutropenia. We conclude that primary cutaneous aspergillosis is increasingly recognized in association with intravenous cannula, intravenous puncture or prolonged contact with arm boards in immunocompromised patients, and that this serious disease can be treated successfully with appropriate management.

BACKGROUND: A burn injury is not only a life-threatening problem for the injured patient but may have serious physical, psychological and financial effects on the individual, the patient's family and society. Despite the high frequency of factors predisposing to burns, preventive measures are few, with a virtual absence of educational campaigns for the population. Thus, the epidemiologic data of patients would be of benefit for the region. OBJECTIVE: The purposes of this study were to understand burn injuries and to plan effective postburn management. METHODS: We reviewed and analyzed the records of 593 cases of burn patients who were admitted to the department of general surgery in Hangang Sacred Heart Hospital from May 1999 to April 2000. RESULTS: Males were more affected than females ; 69.1% were males and 30.9% were females. The 31-45 age group had the highest rate of burns (36.5%). The most common burn type was by flame burn injury (59.9%), followed by scalding burn injury (24.0%). In 49.6% of the cases, the extent of the burned surface was under 20%. The number of deaths in this study was 39 patients (6.6% of total burn patients). The most frequent cause of death was sepsis (51.2%), followed by ARDS (20.6%), and burn shock (17.9%). When 51-60% of the surface area was burned, the mortality was 16.7%, when over 61% of the surface area was burned, the mortality was 41.4%. CONCLUSION: It is evident that the best approach to rectifying the harm caused by burn injury is prevention.

Numerous devices and technics have been devised to facillitate the difficult endotracheal intubation. We have modified the technic of employing a guide inserted retrograde through cannulation of the cricothyroid membrane. We easily used 16G ANGIOCATH for cannulation of the cricothyroid membrane and Angiography guide wire or swan Ganz Introducer wire for retrograde endotracheal intubation.

Leiomyoma of the female urethra is a rare entity. We experienced a case of leiomyoma in the female urethra recently. Forty-one-year-old woman admitted to the hospital with the chief complaint of a painless, protruded large mass outside the vaginal introitus. The mass was excised surgically and confirmed as a leiomyoma pathologically.

Familial adenomatous polyposis(FAP) is a rare hereditary disorder characterized by the development of hundreds to thounds polyps throughout the colon and rectum. Moreover, several extracolonic manifestations are seen. Recently, this disease is recognized as a adenomatous polyposis syndrome which can involve the entire astrointestinal tract. Several reports have demonstrated a high incidence of gastroduodenal polyps in patients with familial adenomatous polyposis. These colon polyps can be eventually developed as colon cancer, if not be treated. So early diagnosis is needed and prophylactic surgery should be erformed. We experienced a case of familial adenomatous polyposis with a large sentinel polyp on the sigmoid colon, presenting hematochezia and mucoid diarrhea. He was early treated before progression to carcinoma by total colectomy, rectal mucosectomy and J pouch ileoanal anastomosis.
