Objectives and Backgrounds : After parotidectomy, some of patients complain gustatory sweating, facial flushing and discomfort in the same area. A series of these symptoms are supposed to be caused by the aberrant regeneration of the secretory parasympathetic fibers to sweat glands and blood vessels of the skin following parotidectomy. In this study, we want to compare the efficacy of thermography to the Minor's starch-iodine test for determining the presence of Frey's syndrome. Materials and Methods : 48 patients who underwent total or superficial parotidectomy from March 2002 to December 2004 were selected for this study. A subjective clinical questionnaire and the objective Minor's starchiodine test were performed to evaluate the incidence of this syndrome. Total 21 patients were confirmed as positive Frey's syndrome and infrared thermography was performed for them. Result : Frey's syndrome occurred in 21 patients(43.8%). The average temperature of parotidectomy site and normal opposite area were $27.65^{\circ}C\;and\;26.41^{\circ}C$ respectively. Thermography showed temperature difference in 20 patient(95.2%) and the difference of temperature was statistically significant above $1.0^{\circ}C$(p<0.001). The severity of symptoms were related with the difference of temperature(p<0.05). Conclusion : Thermography is useful, non-invasive, simple and quantifying method to diagnose Frey's syndrome. Additionally, this geographic diagnosis is available to show the accurate area for botulinum toxin injection.

Purpose: The Inaba's procedure, the treatment of osmidrosis axillae, has the advantages of low recurrent rate and easy to learn, yet it produces early postoperative discomfort and scar formation by tie - over dressing. The authors modified the Inaba's procedure by using delayed suture of the incision wound and omitting tie - over dressing. The comparative study of Inaba's procedure and its modification was performed to confirm the advantages of modified procedure. Methods: The study contains the retrospective analysis of the medical records of 296 patients with osmidrosis who were treated using the Inaba's procedure from December, 1996 to February, 2007. The study also contains the prospective analysis of 20 patients, from March, 2007 to July, 2008, who were treated by the modified Inaba's procedure with delayed suture of the incision wound and gentle pressure dressing instead of tie - over dressing. The operative results of two groups were compared and verified by Mann - Whitney U test(SPSS 12.0). Results: The incidence of complications was 14.5% in the Inaba's procedure, whereas 6.2% in the modified Inaba's procedure. Both procedures have the same basic surgical procedure in terms of the location of incision site and subdermal shaving of the sweat glands, and therefore similar good results were obtained in the aspect of postoperative axillary odor, recurrent rate and postoperative condition of axillary hair. Certainly, the modified Inaba's procedure had better outcome in each element of PSS(Patient Scar Self-Rating Scale), compared to the Inaba's procedure. In addition, the modified Inaba's procedure showed a statistical significance in dressing - related pain reduction and overall satisfaction. Conclusion: The modified Inaba's procedure had advantages of decreased early postoperative complications such as hematoma, discomfort and pain caused by tie - over dressing, and decreased scar formation. However, the drawback was delayed suture of the incision wound after 48 hours.

MFD (Make up Film Deterioration) is a gradual deterioration of applied make up and is a common problem experienced by most foundation users. Our investigation revealed that for 64% of all make up users MFD is their greatest consern is using foundations. Known that the primary cause of MFD is sebum secretion. We observed that the length of time prior to onset of MFD in people who produce high level of sebum varies significantly from person to person. This suggests that other factors besides quantity of sebum production can affect MFD. Control over this factor would, we believe, be key to developing longer-lasting makeups. We studied the relationship between MFD and skin surface conditions. Our study revealed that furrows on the skin surface affect MFD significantly. Sebum reaches the skin surface from sebaceous glands and flows along furrow on the skin. If there are many deep furrows, it takes longer for sebum to overflow. But if the furrows are few or shallow, sebum quickly overflows and spreads over the skin surface where it can degrade the make up film. Therefore even when the volume of sebum produced is the same, the rate of MFD will be different depending on the number and shape of the furrows. A longer-lasting foundation could be produced by matching personal skin condition, but this would be very difficult because individual variations in texture are very large. Therefore we approached the problem by attempting to impose sebum resistance in under make up and foundation. We have developed two new materials and make up products based on our theory. A new fluoroalkyl acrylate-methacrylates copolymer designed for incorporation in under make up is extremely sebum resistant and sweat proof. Another new acrylate polymer designed for inclusion in foundation absorbs sebum and changes to a solid. Usage tests confirm it is possible to reduce MFD by using under make up and foundation which incorporate our new materials to cover where skin furrows are few or shallow

Myoepithelioma is composed exclusively of myoepithelial cells. Myoepithelial cells are ectodermally derived contractile cells that can be routinely identified in many normal tissues having secretory function such as major and minor salivary glands, lacrimal gland and sweat gland. Tumors composed exclusively of myoepithelial cells, so-called myoepitheliomas, are rare-less than 1% of all salivary gland tumors. Grossly, these tumors are well demarcated. The external surface is smooth and may be bosselated. The cut surface is white and homogenous. Microscopically, these tumors are surrounded by a thin fibrous capsule. They are composed of benign-appearing spindle- shaped and/or polygonal cells. Mitoses are rare. Frequently these tumors contain myxomatous stroma which is susceptible to alcial blue stain. Clinically, myoepitheliomas present as slow-glowing, painless masses and can not distinguished from pleomorphic adenomas. Treatment is the same as for pleomorphic adenoma, and the surgical excision should include a margin of normal tissue. Although the majority of myoepitheliomas have behaved in a beingn manner, pleomorphism and mitotic activity have been associated with local aggressiveness.

MiraDry^®, a microwave thermolysis device, is comparably new non-surgical agent in the field of eradication of sweat glands for treating axillary hyperhidrosis and osmidrosis. So far, altered sensation, swelling, and compensatory sweating are widely known as adverse effects of MiraDry^®. Of the few reported MiraDry^®-induced neuropathy cases, median and ulnar neuropathies are common. Although, one case has described radial nerve and posterior cord damage with maximized stimulation intensity, musculocutaneous nerve damage induced by MiraDry^® has not been reported. Here, we report a case of a 30-year-old woman experiencing left hand weakness after receiving MiraDry^® at a local dermatology clinic. Left brachial plexopathy, mainly involving the median nerve and the musculocutaneous nerve with partial axonotmesis, was confirmed by electrodiagnostic studies. Ultrasound evaluation showed corresponding results. This is the first case report of the musculocutaneous neuropathy by MiraDry^®.

Heat-stress remains a costly issue for animal production, especially for poultry as they lack sweat glands, and alleviating heat-stress is necessary for ensuring animal production in hot environment. A high ${\gamma}$-aminobutyric acid (GABA)-producer Lactobacillus strain was used to investigate the effect of dietary GABA-producer on laying performance and egg quality in heat-stressed Hy-line brown hens. Hy-Line brown hens (n = 1,164) at 280 days of age were randomly divided into 4 groups based on the amount of freeze-dried GABA-producer added to the basal diet as follows: i) 0 mg/kg, ii) 25 mg/kg, iii) 50 mg/kg, and iv) 100 mg/kg. All hens were subjected to heat-stress treatment through maintaining the temperature and the relative humidity at $28.83{\pm}3.85^{\circ}C$ and 37% to 53.9%, respectively. During the experiment, laying rate, egg weight and feed intake of hens were recorded daily. At the 30th and 60th day after the start of the experiment, biochemical parameters, enzyme activity and immune activity in serum were measured. Egg production, average egg weight, average daily feed intake, feed conversion ratio and percentage of speckled egg, soft shell egg and misshaped egg were significantly improved (p<0.05) by the increasing supplementation of the dietary GABA-producer. Shape index, eggshell thickness, strength and weight were increased linearly with increasing GABA-producer supplementation. The level of calcium, phosphorus, glucose, total protein and albumin in serum of the hens fed GABA-producing strain supplemented diet was significantly higher (p<0.05) than that of the hens fed the basal diet, whereas cholesterol level was decreased. Compared with the basal diet, GABA-producer strain supplementation increased serum level of glutathione peroxidase (p = 0.009) and superoxide dismutase. In conclusion, GABA-producer played an important role in alleviating heat-stress, the isolated GABA-producer strain might be a potential natural and safe probiotic to use to improve laying performance and egg quality in heat-stressed hens.

유전적인 외배엽 이형성증에 의해 무치증 혹은 부분적 무치증을 가진 환아들은 치조골 발육의 부족으로 나타난 감소된 수직고경으로 인해 어린 나이에서 노인과 같은 안모를 가지게 된다. 이에 어린이들은 또래의 어린이들과 잘 어울릴 수 없게 되고 소외감과 정서적 위축감을 느끼게 된다. 수직고경을 고려한 보철적 치료를 통해 적절한 기능과 심미적인 개선을 이룰 수 있도록 도와주는 것이 치과의사의 중요한 역할이라 하겠다. 이에 저자는 경희대학교 치과대학 부속치과병원 소아치과에 내원한 부분적 무치증을 동반한 외배엽 이형성증을 가진 환아에서 치과치료를 통한 심미적, 기능적 결함을 개전하면서 다음과 같은 결론을 얻었기에 보고하는 바이다. 1. 맹출 영구치 위에 클래스프를 위치시켜 의치유지력에 도움을 주었으며 상하악 피개의치의 장착으로 교합고경을 회복하여 저작, 발음, 심미적인 개선이 이루어졌다. 2. 피개의치의 이용으로 교합평면의 설정과 의치의 유지와 안정을 도모하였고, 맹출한 치아를 보존하고 남아있는 치조골의 폭과 높이를 유지할 수 있었다. 3. 치료를 통해 환아는 외모에 자신감을 가지고 치과환경에 익숙해져 긍정적인 태도를 가지게 되었다. 4. 주기적인 내원을 통한 영구치 상태와 성장, 발육동안의 의치의 관찰로 의치의 이장, 재제작이 요구된다.
