Ptosis of the upper eyelid is one of common deformities of the eye region. To obtain the best surgical result in ptosis, it is necessary to select the appropriate operation for each case according to levator function, degree of ptosis, its etiology and other factors. For the correction of the congenital ptosis with very poor or absent levator function, frontalis suspension with various many materials and direct transplantation of the frontalis muscle have been used by many authors. Each of the above has its specific virtues and inherent shortcomings. On the basis of comparative study of the conventional techniques and anatomical study of the eyebrow region, we designed a superiorly based frontalis myofascial flap. The orbital portion of the orbicularis oculi muscle was included in the distal end of the frontalis myofascial flap to lengthen the flap. According to our results, this technique of frontalis myofascial flap has several advantages compared to Song's direct frontalis transplantation : (1) the operation can be done under a local anesthesia at the out-patient department with simple procedure and less bleeding. (2) the forehead wrinkles are to not disturbed, (3) this procedure needs only a single incision and does not disturb the important anatomic structures around the eyebrow region.

Treatment of cancer of the cervical aerodigestive tract is a challenging problem due in part to the difficulty in reconstruction and subsequent reestablishment of pharyngoesophageal continuity. From May 1, 1989 to Feb 1, 1990. 4 patients underwent immediate reconstruction utilizing free forearm flap transfers following resection of pharyngoesophageal neoplasm. An island flap was condition, connected to the radial vascula pedicle by fasciocutaneous branches, to reflect the condition of a hidden fabricated free forearm flap. Stricture is the most troublesome complication in a conventional free forearm flap. Two small triangular flaps were designed and inserted in both lateral esophageal wall defects to prevent circular contracture. The outer layer sutures were anchored to surrounding rigid structures to withstand shrinkage and circular contraction. The problem of stricture was solved by these improved procedures. This one-stage, less invasive, easily monitored operation for pharyngoesophageal reconstruction can be considered useful in place of a free jejunal transfer.

Reconstruction of the penis is indicated in a traumatic or surgical amputation, congenital penile absence, micropenis, male pseudohermaproditism, or transsexualism. Initially, penile reconstruction has been performed using a local flap, but often failed because of the multiple procedures, fistula or stricture of the urethra, and no sensation of the phallus. Ideally, penile reconstruction should be a one-stage procedure, creating a phallus with both tactile and aerogenous sensibility, water-tight neourethra allowing for voiding while standing, enough bulk with stiffness, and aesthetically acceptable appearance. Since August 1989 we have constructed a penis in 4 patients. We selected the radial forearm flap as a donor site because it offers a reliable artery, veins, nerves, and stiffner. It also offers thin, malleable skin with adequate width and length. We have followed these patients from 5 months to 10 months. All operations were successful except for one fistula formation.

전기화상후 Prostaglandin F2a와 Thromboxane B2의 증가에 대한 Flurbiprofen, Prednisolone 및 Gabexate mesilate의 억제효과

This study was conducted to clarify the inhibitory effect of flurbiprofen, prednisolone, and gabexate mesilate on the synthesis of prostaglandin F2a and thromboxane B2 in the tissue of electrical burn. one hundred sixty Sprague-Dawley rats, 250gm of body weight in average, were divided into 4 groups of control, flurbiprofen, prednisolone and gabexate mesilate administred group. Fourty rats of the each group were subdivided into 1st, 2nd, 4th, 7th postburn day with 10 rats in each subgroup. Ten rats were used for normal values of prostaglandin F2a and thromboxane B2. Flurbiprodfen 30mg/kg was given per mouth, and prednisolone acetate 5mg/kg and gabaxate mesilate 50mg/kg were administred intramuscularly 5 minutes after burn injury and then once a day. All but bone tissue of within 2cm area of the current entry were harvested and ground into homogenate. The levels of prostaglandin F2a and thromoboxane B2 were measured by Radioimmunoassay. The results were as followings: In normal rat tissue, the level of prostagland F2a and thromboxane B2 were 15.8±1.8 and 17.6±2.8ng/mg protein in each. In the control group the levels of both prostaglandin F2a and thromboxane B2 increased abruptly to 5 times and 7 thimes in the first day and maintained the same level in the second day. After then they rapidly decreased and returned to a near normal level in the fourth day. The increase of thromboxane B2 was more remarkable than that of prostaglandin F2a. In the flurbiprofen group, the level of thromboxane B2 was not inerease but kept at a normal level. The average level of prostaglandin F2a in the post-burn first and second day was 59.5% lower than of the control group. The average level on the post-burn first and second day was 61% lower in thromboxane B2 and 33% lower in prostaglandin F2a in the prednisolone group, and 68% lower in throboxane B2 and 48% lower in prostaglandin F2a in the gabexate mesilate group, compared to the control group. These findings suggest that electrically injured tissue is vigrously progressive due to rapid increase of thromboxane B2 and prostaglandin F2a, as inflammatory mediators, in the post-burn first and second day, is nonprogressive after the post-burn fourth day. The flurbiprodfen was the most effective of the three drugs(flurbiprofen, gabexate mesilate, prednisolone in order of effectiveness) to suppress the synthesis of thromboxane B2 prostaglandin F2a of the electrieally injured tissue.

Brachymetatarsia frequently affects the fourth toe, and is more common in females, The etiology is obscure but the premature closure of epiphysis results in early union and cessation of metatarsal growth. The abnormally short metatarsus is both clinically and radiographically evident with an associated shortened and contracted toe. The deformity is usually asymptomatic but produces a serious cosmetic and psychological problems. For the corrction fo brachymetatarsia, many different surgical alternatives have been presented. We adopted the modified Jinnaka's method : interposing the autogeneous cranial bone graft within the metatarsophalangeal joint of the metatarsophalangeal joint for reducing the tension dorsally on the digit. Postoperatively the short leg splont was removed two weeks after the operation. During the next four weeks, the walking cast was applied and weight bearing was begun. During recent 4 years, 9 brachymetatarsia developed in the 4th toe in 5 patients were treated with this technique and good postoperative results were achieved in cosmetic and functinal aspects. This method has following merits. 1. The cranial bone is less absorbable than the rib or iliac crest. 2. The lengthening of the dorsal skin is easily obtained by means of Z-plasty over the dorsal skin of the metatarsophalangeal joint. 3. By interposing a bone graft within the metatarsophalangeal joint, bone lengthening of two centimenters or more could be achieved and the patients could walk without fracture of the grafted bone except one toe, in which pseudojoint is formed with normal gait.

Levator Aponeurosis and Muller Muscle Plication Reinforced With Levator Sheath Advancement for Blepharoptosis Correction

Byun, Jin Suk,Hwang, Kun,Lee, Sang Yun,Kim, Hak Tae,Kim, Kenneth by Mutaz B. Habal, MD. 2017 JOURNAL OF CRANIOFACIAL SURGERY - Vol.28 No.7

ABSTRACT: The authors innovated the levator aponeurosis and Muller muscle plication reinforced with levator sheath advancement (AMPSA) for blepharoptosis correction. The orbital septum was opened 1 mm above its fusion with the levator aponeurosis. The preaponeurotic fat was retracted and the thickened part of the levator sheath was identified. Two plication sutures were made: medial suture at the medial border of the pupil and lateral between the lateral border of the pupil and the lateral limbus. A needle with 6-0 nylon thread first bit the tarsal plate approximately 1 mm below its upper border, then bit the levator aponeurosis and the Muller muscle together at 3 to 6 mm above the upper border of the tarsal plate. The needle bit 1 to 3 mm of the thickened part of the levator sheath and the suture was tied. A total of 116 eyes were operated on using levator aponeurosis and Muller muscle plication (AMP), and 79 eyes using AMPSA. The mean follow-up period was 11.4 months. In the AMP group, the postoperative marginal reflex distance-1 (MRD-1) (3.8 ± 0.2 mm) was significantly greater than the preoperative MRD-1 (2.7 ± 0.3 mm) (P < 0.001). In the AMPSA group, the postoperative MRD-1 (3.5 ± 0.3 mm) was also significantly greater than the preoperative MRD-1 (1.7 ± 0.4 mm) (P < 0.001). The improvement in MRD-1 was greater in the AMPSA group (1.7 ± 0.4 mm) than in the AMP group (1.1 ± 0.3 mm) (P < 0.001). The difference in the MRD-1 outcome between AMPSA and AMP (0.6 mm) was obtained by advancing the thickened part of the levator sheath. AMPSA may be an effective procedure for correcting blepharoptosis.

The purpose of the study was to investigate the effect of homestay and conln1ifing factors to second language learning of 13 Korean students in the U.S.A They participated in 3 week summer homestay as a part of a 6-month TESOL certificate program in a U.S. university. They were given pre- and post-tests consisting of listening, speaking, reading, and writing. They were also required to complete a survey, journal, and storyboards about the homestay experience. ``The analysis results demonstrated that they tended to communicate with a certain member of the hot family because of the person`s outgoing personality and that they were given proficiency-appropriate help for their English. There was an ignorable amount of score improvement in listening and reading. Speaking showed a small amount of score improvement and the fluency component of the speaking skill played an important role in elevating the score. Students acknowledged increased interaction with their American host families with their native country-related topics and current topics. The contexts that promoted interaction were mealtime, playing games, shopping with the host family, and helping the host family.

미국 민사소송제도에서 약식판결 (Summary Judgment)의 역할과 변화 -정의, 효율, 그리고 이데올로기-

변진석 ( Jin Suk Byun ) 건국대학교 법학연구소 2014 一鑑法學 Vol.0 No.27

This paper attempts to analyze Rule 56 Summary Judgment of Federal Rules of Civil Procedure in terms of the change and development of purpose and operation over the entire history of the rule. The rule has two conflicting nature. One is the pursuit of efficiency and the other is, as a result of the first nature, the possibility of restricting people`s right to day in court. This two faced aspect of the Summary Judgment resulted in a three-part, cyclical change from emphasis on the efficiency of early 20th Century, through, post 1938 reformist period, limited use of the rule to the mid 1980s` active expansion of the use of summary judgment. Behind this change, there have been laissez-faire capitalism of pre-Depression period, and New Deal reform and liberal period of 1930s through to 1960s. Finally, as a result of explosion of litigation in the 1970s and conservative trends in the 1980s of American society, the Supreme Court change the course of summary judgment with Trilogy of Summary of 1986 expanding and supporting the use of summary judgment.
