An axial-pattern flap can be transferred as the free-flap and has many merits over a random-pattern local flap. However, this has limitations of available vascular architecture and donor site. To overcome these problems, many types of prefabricated flaps have been designed using vascular bundles. It is possible to convert a random-pattern flap to a neovascularized axial-pattern flap by transferring a vascular pedicle. In an attempt to study the effects of prefabrication using vascular bundles, the survival rate between random-pattern flap and prefabricated axial-pattern flap was compared in this study. The rabbits were divided into two groups. The control group was consisted of the random-pattern flap and the prefabricated group was consisted of the prefabricated axial-pattern flap using femoral vascular pericles of rabbits. Femoral vascular pedicles were transferred under the 5x5cm lower abdominal flaps without any perivascular tissue. Three weeks later, random-pattern flaps were elevated without any axial vascular pedicle and prefabricated flaps were elevated based on the transferred femoral vascular pericles. The survival rate of the flaps in the control group and experimental group was 67.37% and 98.87% respectively. Based on the result of t-test there was significant difference between two groups. According to these results, it is concluded that prefabricated flap using transferred vascular pedicle was more effective than random-pattern flap. We think that this technique is versatile for wound repair and for use in other aspects of plastic and reconstructive surgery.

Augumentation rhinoplasty using autogenous cranial bone graft (outer table) can be used more successfully than other methods. In patients with congenital or posttraumatic severe saddle nose deformity and lateral deviation, cranial bone graft is an excellent method of augumentation. The advantages of cranial bone graft compared with traditional method of bone graft are summarized as follows; 1. Easy to reach donor site 2. Abundance of material 3. Little pain and functional disability 4. Shorter hospitalization period 5. Inconspicuous donor scar 6. No secondary deformity of donor site 7.Appropriate curvature can be obtained by proper selection of donor site. With the above advantages, we conclude that augumentation rhinoplasty using split cranial bone graft is a good method in correction of congenital or posttraumatic deformity of nose.

We report a case of acantholytic dyskeratotic epidermal nevus in a 28-year-old female. The patient showed unilateral, asymptomatic, grouped, 2 mm sized, brownish, follicular ant non-follicular, keratotic papules disposed along Blaschko´s lines on the right side of th back, flank and abdomen. She had had this condition for 4 years. The biopsy specimen obtaine, from the abdomen showed hyperkeratosis, parakeratosis, acanthosis, acantholytic suprabasal clefts, corps ronds, and grains. Although cryotherapy with liquid nitrogen was per formed on half of the lesions, the whole skin lesions healed with focal hypertrophic scars 4 weeks later. There was no recurrence after a 12 months follow-up period. To our knowledge this is the first reported case of acantholytic dyskeratotic epidermal nevus in Korean dermatologi, literature.

BACKGROUND: This study was conducted to compare the clinical and radiological outcomes of the locking hook plate fixation (HP) technique and the single tight rope (TR) technique applied for acute high-grade acromioclavicular (AC) joint separations. METHODS: Between 2009 and 2014, 135 consecutive patients with acute AC joint separation Rockwood types III, IV, and V were subjected to surgical reconstruction. One hundred fourteen patients (84.4%) were available for retrospective evaluation. Of them, 62 and 52 were treated using the single TR group and clavicular HP group techniques, respectively. The visual analogue scale, Constant, American Shoulder and Elbow Surgeons (ASES), and Taft scores were used for clinical assessment. Postoperative shoulder range of motion was also assessed. An anteroposterior radiograph of the coracoclavicular distance (CCD) was obtained to evaluate the radiographic signs of recurrence. RESULTS: The TR group patients had better Constant, ASES, and Taft scores than the HP group patients. The loss of reduction in terms of the CCD did not differ between groups. Subacromial osteolysis was observed in 34.6% of the cases in the HP group. However, there were no significant differences in the clinical outcomes between the patients with and without osteolysis in the HP group. Subcoracoid osteolysis, drill tunnel widening, and metal displacement were observed in 3.2%, 22.6%, and 4.8% of the cases in the TR group, respectively. CONCLUSIONS: The single TR technique was relatively more effective at treating acute high-grade AC joint injuries than the HP fixation technique (level of evidence: therapeutic; retrospective comparative study, Level III).

A clinical study was performed on 940 cases of essential hypertension observed at Dept. of Internal Medicine of Seoul National University Hospital during a period of last seven years from 1971 to 1977. The followings were the results: 1. The incidence of hypertensive patients was 13.8% among all medical in-patients and 68.2% among all cardiac in-patients. 2. The highest occurence was observed in sixth decade and accounted for 34.2% of all cases and least occurence was in second decade of life which accounted for 0.6% of all cases. No difference was found in age distribution between both sexes. The male to female ratio was 1.2:1. 3. The mean value of blood pressure was 178.1+/-21.8/107.4+/-12.3 mmHg and tended to increase with age at least over the decades from second to seventh and there was tendency to decrease after the eighth decade. No paticular difference in blood pressure levels was found in both sexes. 4. The most outstanding symptom was headache which was found in 51.5% of all cases. Dizziness, dyspnea and palpitation were the next orders in frequency. There was a general trend of the the subjective symptoms which were more pronounced in younger than older patients. 5. Hypertensive retinopathy was found in 83.3% of all cases. Hypertensive retinopathy of K-W grade II was found in 36.1% of all cases and was the most frequent finding among the Keith-Wagener grades. Malignant hypertension of K-W grade IV was found in 4.2% of all cases and the largest numbers were between the fourth and fifth decade of life. 6. The abnormal retinal finding was found to be rather proportional to the blood pressure levels. 7. Albuminuria was detected in 56.2% of all cases and it was more frequent in male than in female patients. 8. The appearance of albuminuria seemed to have a close correlation with hypertensive retinal change and blood pressure levels. 9. Electrocardiographic abnormalities were associated in 71.9% of all cases. The most frequent association among electrocardiographic abnormalities was left ventricular hypertrophy which accounted for 45.2% of all cases. There was the reverse correlation between the normal electrocardiogram and degree of blood pressures. The finding of left ventricular hypertrophy and degree of blood pressures were closely correlated. 10. Cerebrovascular accident, renal failure, congestive heart failure and atrial fibrillation were four major complications. It was recorded in 26.5%, 10.4%, 5.4% and 2.0% of all cases respectively. The complications were common in men than in women. 11. Renal failure, congestive heart failure and myocardial infarction were closely corelated with hypertensive retinopathy.

The ideal breast reduction should create beautiful breasts with limited scars. Unfortunately, no surgeon has ever been able to produce such a result. Most recent breast reduction techniques tend to produce minimal breast scars and avoid the classic inverted-T incision. The vertical mammaplasty can be used in mild to moderate cases of breast reduction, producing consistently good, stable results with limited scars. This technique uses adjustable preoperative markings, an upper pedicle for the areola, and a central breast reduction with limited skin undermining. The shape of the breast is created by suturing of the gland and does not rely on the skin. The adjunctive use of liposuction in fatty breasts can be considered safe and efficient. We have performed reduction mammaplasty using the vertical mammaplasty technique in 12 patients. Overall number and extent of complications were small, and patient satisfaction was high for this procedures. The advantages of vertical mammaplasty technique compared with other methods are as follows ; 1. The markings are adjustable to nearly all patients. 2. Stable contours are produced because the gland is strongly sutured. 3. Few postoperative complications occur. 4. Limited scars(only vertical scars) are created 5. The procedure is easy to learn and perform.

Since 1981 there have been many clinical and experimental reports of venous skin flap, which was nourished solely by venous blood, or by arteria1 blood flowing through the venous network. But, the mechanism of survival has not been completely understood. Unfortunately, partial flap necrosis and unstable postoperative recovery course make surgeons hesitant in choosing the venous flap. In order to increase the survival of a venous flap, surgical delay procedure or increasing the number of draining veins have been successfully tried. Historically, tissue expansion has the same effect on skin vascularity as delaying the area The increase in the caliber of the blood vessels and adequate neovascularization of the expanded tissue can increase the size and vascularity of the flap while allowing primary closure of the donor defect. In order to investigate the survival pattern of expanded arterialized venous flap, the author conducted the following study. The arterialized venous flaps were divided into control and two experimental groups. The conventional nonexpanded arterialized venous flap of 5x5 cm in size was used as control group On experimental group I, preoperative tissue expansion was performed during 3 weeks, and then arterialized venous flap with the same size was made. On experimental group II, expanded arterialized venous flap with 10x10 cm in size was made. The mean survival rate of control, experimental group I and II was 81.2%, 98.8% and 99.1%, respectively. The angiogram of expanded flap showed dilatation of the vessels and neovascularization with tortuous vessels to the peripheral area of the flap. In conclusion, the survival of expanded arterialized venous flap was superior than that of conventional arterialized venous flap. The expanded venous flaps appear to be useful in producing large flaps, in decreasing marginal necrosis of the flap as well as minimizing donor defect.

Proliferative vitreoretinopathy (PVR) is a main cause of failure in retinal reattachment surgery. There have been many studies about the inhibition of proliferative vitreoretinophthy with several drugs. Authors investigated the inhibitory effect of proliferative vitreoretinopathy and retinal toxicity with various concentration of daunorubicin after intravitreal injection into the eyes of the pigmented rabbit. 7 pigment rabbit (11eyes) were used as subjects. After lensectomy and vitrectomy, control group was injected dermal fibroblast and F-BSS, and treatment group was injected dermal fibroblast and 5, 10, 15, 30 nmol Daunorubicin. At two weeks after intravitreal injection, both group were enucleated and examined with gross finding, light--microscopy, and electronmicroscopy. In all control group, proliferative vitreoretinopathy was found, but only preretinal membrane formation was found in 5, 10 nmol Daunorubicin injected group. In 15 nmol Daunorubicin injected group, the retina structure was preserved normally. In 30 nmol Daunorubicin injected group, the retinal outer segment was degenerated in microscopic finding. These results show that Daunorubicin has a potent effect on proliferative vitreoretinopathy, especially in 15 nmol, but retinal toxicity is suspected in marethan 30 nmol.
