1.ENDOSCOPIC FOREHEAD LIFT COMBINED WITH ALLODERM(R) IMPLANTATION TO CORRECT FOREHEAD DEEP WRINKLES.
Journal of the Korean Society of Aesthetic Plastic Surgery 1999;5(2):281-287
Forehead deep wrinkles make man's face ugly. Especially, in case that a young people has short forehead, one or two forehead deep wrinkles is likely go give a aggressive impression to people. Traditional forehead lift basically not only perfrom the selective excision of frontalis muscle which cause forehead wrinkles, but extend the width of forehead by practical lift through scalp excision. Recently, various filling materials such as collagen have been developing, and laser resurfacing and endoscopic plastic surgery has gradually been generalized, so the frequency of the traditional forehead lift which needs the extensive operation through coronal incision is gradually diminished. But collagen injection is repeatedly taken every regular times and it has a weak point that the width of forehead cannot be regulated. Laser resurfacing can't solve the problem of deep wrinkles. The purpose of endoscopic brow lift which has been generalized currently is mainly brow lift, and so this method is not good for deep wrinkles because it can't modualte frontalis muscle which cause forehead transverse wrinkles. Recently it has been reported that Alloderm composed of dermal collagen from cadavar skin is universally used in covering as well as filling up soft tissue defect and its usability is also successful. Authors recently correct three young persons who have forehead deep wrinkles by combination of endoscopic forehead lift and subcutaneous Alloderm implantation under the wrinkles for 2 years. At first, we extended the width of forehead and smoothed the depth of wrinkles by endoscopic brow lift. After having endoscopic operation, we inserted Alloderm in subcutaneous pocket and performed suspension suture outside. The average increase of forehead width is 5 mm and all patients had corrected transverse wrinkles remarkably. During the 9 months, wrinkles didn't recur and implanted Alloderm also didn't absorbed. As a better method, authors reported that combining endoscopic brow lift with Alloderm implantation for the correction of short forehead and deep wrinkles could be used in place of traditional forehead lift.

OBJECTIVE: The aims of this study were to analyze the natural history of patients with pseudomyxoma peritonei originated from mucinous ovarian tumor, evaluate clinical and pathologic variables, and review our experience with available therapeutic modalities. METHODS: Six patients were treated for pseudomyxoma peritonei originating from mucinous ovarian tumor at Severance Hospital between 1990 and 1998. The data were collected retrospectively and all charts were reviewed RESULTS: The mean age at diagnosis was 51 years, and most common symptoms were abdominal distension. Pseudomyxoma peritonei was found in association with five mucinous ovarian tumors of borderline malignancy, and one ovarian mucinous adenoma. All patients underwent surgical staging and cytoreduction, three patients received postoperative adjuvant chemotherapy and, of these, two developed recurrence. With respect to survival, all patients were alive, four were alive and free of disease, two were alive with disease at the end point of study. CONCLUSION: Pseudomyxoma peritonei is commonly associated with borderline mucinous ovarian tumors, and is a frequently relapsing and protracted disease. But aggressive and repeated debulking surgery is recommended for long survival.

Flap survival is critical to the success in reconstructive surgery, there have been many investigations to increase the blood supply to the flaps such as surgical delay and pharmacologic delay. Prostaglandin(PG) is released from various tissues including blood vessel in response to physical stimulus. Among the Prostaglandins, PGE1 has been proven to be a vasodilatation property and many authors have demonstrated its effect to increase blood supply after random cutaneous flap surgery. Clinically, however, muscle flap or musculocutaneous flap is more significantly used in reconstructive surgery and hemodynamic effects of PGE1 of this type of flap are still not documented. The authors designed the random muscle flap to study the hemodynamic effects of PGE1 of the muscle flap. Superior based rectus muscle flap was elevated from rats and the superior epigastric artery, its major vascular pedicle, was ligated to create the random-type muscle flap. Twenty two rats were divided into two experimental groups and each group had 11 rats; Group I: No drugs Group II: PGE1 injection group for 7 postoperative days intraperitoneally The average muscle flap survival rate of group I was 46+/-3.0 precent and it had a higher survival rate than the control group(23+/-4.3%). The muscle flap survival rates showed significant differences between the two groups (p< 0.005) This study shows that the administration of the PGE1, in clinical usage of the rare random muscle flap with a pedicle injury or musculocutaneous flap with the risk of distal cutaneous flap necrosis, such as TRAM flap, which might be much safer and popular.

Cobb syndrome is a rare neurocutaneous angiomatosis characterized by a vascular skin nevus associated with a spinal cord angioma of the same metamere. A 14-year-old girl had an asymptomatic large cutaneous hemangioma distributed from the TI dermatome downward to the L3 dermatome since birth and complained of a gait disturbance and urination difficulty for 1 year. A biopsy specimen in the skin lesion revealed the findings of capillary hemangioma. From C7 downward to L4 posterior epidural hemangioma composed of arteriovenous and cavernous components was diagnosed by radiological examination and surgical exploration. Because of very extensive cord hemangioma, only partial removal of the tumor at T11, T12 and L1 level was performed and postoperatively she was transferred to a special facility for rehabilitative therapy.

Primary or metastatic malignant melanoma can mimic benign blue nevus in rare cases, making the diagnosis challenging. Herein, we report an exceptionally rare case of blue nevus-like melanoma and its blue nevus-like metastasis which was detected by catheterized urine cytology. The patient presented with blue-colored papuloplaques on his temple which were diagnosed as blue nevus-like melanoma on punch biopsies. While he was admitted for administration of chemotherapy, hematuria was detected. Catheterized urine cytology revealed singly scattered oval to spindle-shaped pigmented cells with a moderate degree of variation in shape and size. Many of them had small nuclei with indiscernible to inconspicuous nucleoli while only a few cells showed nuclear enlargement and nuclear hyperchromasia, which could be diagnostic pitfalls. Most of the cells on the smear were positive for HMB45 immunostaining, which confirmed the diagnosis of metastatic blue nevus-like melanoma. To the best of our knowledge, the present case is the first report describing cytomorphologic findings of blue nevus-like metastasis of melanoma in the urine specimen.

OBJECTIVES: This study was to evaluate the impacts of simultaneous exposure to noise and mixed solvents on workers'hearing threshold level (HTL) over five-year period. METHODS: The study was conducted by interview and annual audiometric test on workers in ship building industry from 1994 to 1998. The cases(workers who exposed to noise and mixed solvent simultaneously) were 43 male workers and controls (workers who exposed to nolle) were selected by matching method with regard to age, sex, carrier, and noise exposure level. To assess the impacts of solvent exposure on hearing threshold level, with considering other factors, general liner model was used. RESULTS: 1. The audiogram of all subjects showed typical sensorineural hearing loss pattern. The mean HTLe were increased at high frequency (4000HB and 8000Hz) for study period. 2. The HTLs of cases were more increased than those of controls at high frequencies (4000Hz and 8000Hz), but there was not statlstical significance. 3. The impact of age on the HTL was statistically significant at 250Hz and 500Hz (p(0.05), and the impact of noise on the HTL was statistically significant at 250Hz, 2000Hz and 4000Hz (p(0.05), but the impact solvent exposure on the HTL was not significant. 4. The changes in HTLs of cases were higher than those of controls at high frequency, there were not statistical significance at 4000Hz, but only at 8000Hz (p=0.087). 5. Statistical analysis of the general linear model implicated that the changes in HTL was impacted by noise exposure bevel significantly (p=0.031) and Impacted by solvent exposure weakly (p=0.087) at 8000Hz. CONCLUSIONS: The results of this study suggest that workers who simultaneously exposed to noise and mixed solvent were at risk for more affected HTL than those exposed to noise exposure only, but we could not find definitive evidence. Further detailed studies must be made in large number of workers.

This study aimed to investigate the prevalence of depression among Koreans living in urban and rural areas, stratified by socioeconomic status. The study included 216,765 participants from the 2017 Korean Community Health Survey. Depressive symptoms were assessed using the PHQ-9, with a score of 10 or higher indicating depressive symptoms. Residences with the words Eup and Myeon in their addresses were categorized as rural areas, and residences with Dong in their addresses as urban areas. Socioeconomic status was evaluated by household income and education level. A Poisson regression analysis with sampling weights was conducted and adjusted for demographic, lifestyle, socioeconomic status, and comorbidity. The adjusted prevalence rate of depressive symptoms was 3.33% (95% CI, 3.21-3.45) in urban areas and 2.59% (95% CI, 2.43-2.74) in rural areas. The prevalence of depressive symptoms in urban areas was 1.29 times (95% CI, 1.20-1.38) higher than in rural areas. The prevalence rate ratio for depressive symptoms in urban areas compared to rural areas sorted by monthly incomes was 1.39 (95% CI, 1.28-1.51) for less than 2 million won, 1.22 (95% CI, 1.06-1.41) for 2 to 3.99 million won, and 1.09 (95% CI, 0.90-1.32) for more than 4 million won, and the urban-rural difference was more evident in lower household income subjects (p for interaction=0.033). However, urban-rural differences did not differ according to sex, age, or education level. In conclusion, we found urban-rural differences in depressive symptoms in a representative sample of Koreans, and revealed that these differences may vary according to income level. These results suggest that mental health policy must consider the health disparities according to residence and income.

The determination of proliferative activity in the colorectal mucosa has been used for different purposes as the estimation of cancer risk and the assessment of disease activity in ulcerative colitis. But the prognostic significance of proliferative activity in colorectal carcinomas remains controversial. To investigate the prognostic significance of proliferative activity in colorectal carcinomas, the author estimated the proliferative activity immunohisto chemically using the monoclonal antibody PCNA and compared with clinicopathological data in 62 colorectal carcinomas. The results were as follows: 1) The reactivity of PCNA was more pronounced at the infiltrative margins of the tumors and tumor cells within the vascular or lymphatic channels. 2) The mean PCNA index of colorectal carcinomas was 40.5?0.4%. PCNA indices had positive correlations with lymph node invasion(p<0.05), liver, metastasis(p<0.05), Dukes' stage(p<0.01) and TNM classification(p<0.01), and didn't correlated with location of tumor, size of tumor, histological type and lymphtic or vascular invasion. 3) The patients with high PCNA index(more than 45%) represented higher recurrence or metastasis rate(37.5%) than those with low PCNA index (less than 45%)(19.3%) in Dukes B or C colorectal carcinomas during the follow-up periods, but not significant statistically. These results suggested that the reactivity of PCNA may be a useful prognostic factors in colorectal carcinomas.

If orthodontists and restorative dentists establish the interdisciplinary approach to esthetic dentistry, the esthetic and functional outcome of their combined efforts will be greatly enhanced. This article describes satisfying esthetic results obtained by the distribution of space for restoration by orthodontic treatment and porcelain laminate veneers in uneven space between maxillary anterior teeth. It is proposed that the use of orthodontic treatment for re-distribution of the space and the use of porcelain laminate veneers to alter crown anatomy provide maximum esthetic and functional correction for patients with irregular interdental spacing.
