The purpose of this study was to determine whether vasodilation occurs when interferential current is applied to the cervical sympathetic chain and peripheral sympathetic nerves. A digital thermometer was used to record skin temperature change. The protocols used for interferential stimulation were 90-100 Hz, applied for 20 minutes via two pairs of electrodes 1) to the throat and 2) to the forearm. Forty subjects were stimulated at each of the two sites. There was no significant correlation between inital skin temperature, sex or age and temperature change. Even though there was a statistically significant temperature increase with cervical sympathetic chain stimulation, this had no clinical vasodilatory effect. More research on interferential current stimulation is needed so that the potential benefits to normal subjects and patients is better understood.

A 26 year old male patient had admitted to the department of plastic surgery for the treatment of skin defect of forearm and spastic contracture of right hand, attributable to burn injury following carbon monoxide intoxication. After receiving skin graft the patients tenotomy of flexor tendons, the patients was consulted to pain clinic for further evaluation and treatment of allodynia, hyperalgesia, and hyperpathia with marked emotional insufficiency. The patient was treated with stellate ganglion blocks, intermittent or continuous epidural blocks, and intermittent brachial plexus blocks for 3 months. with this treatment the patient's pain level improved to(VAS 10 to 4~5) and was discharged. The patient was readmitted 3 months later, due to the aggrzvation of pain. Brachial plexus blocks were given again by interscalene, supraclavicular, or axillary route, sometimes using a catheter, together with cervical epidural blocks. Tricyclic antidepressant was also prescribed. The results were remarkably good(VAS 2~3) and the patient did not require any further analgesic medication.

The objective of this study was to evaluate whether nutrient intakes and serum biochemical indices are associated with the skin condition of humans. Anthropometric data, skin surface hydration, ceramide content, dietary intake of nutrients and serum lipids (total cholesterol, HDL-, LDL-cholesterol, TG, MDA: malondialdehyde, TAS: total antioxidant status) were obtained from 36 healthy young women. Subjects were classified into 2 groups {LM: Low Moisture Group (n = 20) , HM: High Moisture Group (n = 16)} by forehead skin hydration. The results of this study were as follows: The average age, BMI, total body water, LBM, body fat$\%$, WHR, forehead hydration, ceramide content were 20.2 yrs, 20.7, 28.81, 39.2 kg, $28.0\%$, 0.8, $44.3\%$, and 1.05 $\mu$g/$\mu$g protein, repectively. The intakes of SF A (saturated fatty acid) , MUFA (monounsaturated fatty acid) in the HM group were significantly higher (p < 0.05) than in the LM group, but zinc intakes in the LM group were higher than in the HM group. Serum levels of TAS in the LM group (1.27 mmol/l) were significantly higher (p < 0.05) than that of in the HM group (1.20 mmol/l). Whereas other lipid levels were not significantly different, intakes of vitamin $B_{6}$ and folate showed significant positive correlation with the forehead hydration (r = 0.447, r = 0.377). Intakes of calcium and phosphorus showed significant negative correlation with forearm ceramide content (r = -0.496, r = -0.485). Several associations between nutrient intakes and skin conditions were observed, indicating that changes in baseline nutritional status may affect skin health.

The purposes of this study were to measure skin temperature and blood flow on the contralateral upper extremity when heat is applied to one upper extremity, were to compare the effect of contrast bath. The subjects were 38 healthy adults with no history of peripheral vascular disease. The subjects of contrast bath were 18 persons and the subjects of warm bath were 20 persons. The subjects of one group were seated with their right arm in water($42^{\circ}C$) up to the mid-forearm. The subjects of the other group were seated with their right arm up to the mid-forearm in water which was changed from warm to cold using the contrast bath technique. The continually changing temperatures and blood flow were measured by an independent observer at intervals of 10, 15, 20, 25 and 30 minutes respectively after the start of the procedure. The results were as follows. The temperature of the warm bath group rose 4.28% over the pre-experimental temperatures and the temperature of the contrast bath group rose 3.41%. There was no statistically significant difference between the two groups. The blood flow of the warm bath group rose 8.31% over the pre-experimental blood flow and the blood flow of the contrast bath group rose 17.24%. There was a statistically significant between the two groups 20 minutes after the start of the procedure. Thus the contrast bath is a more effective method than the warm bath to increase blood flow.

Background and Objectives: The reconstruction is very important in Head and neck cancer surgery to repair the defect created by resection of tumors, to enable successful wound healing, to restore function and to provide acceptable cosmesis. The radial forearm free flap has been the most useful reconstructive flap because it provides a moderate amount of thin, pliable, relatively hairless skin and comparatively simple to do with minimal morbidity. The aims of this study is to estimate the outcome of the reconstruction with radial forearm free flap with the several factors in 140 head and neck cancer cases in our hospital for last 10 years. Materials and Methods: Retrospective review of the records of 140 patients underwent resection of the head and neck tumors and reconstruction with a radial forearm free flap from 1993 to 2003. The age, sex of the patients, Primary site, the complication of donor and recipient site, flap survival rate, median time to start diet, patient subjective symtoms about swallowing and articulating and the fact of revision reconstructive surgery were analyzed. Results: In primary pathologic site, 56 cases were oral cavity cancers, 44 cases, oropharyngeal cancers and 22 cases, hypopharyngeal cancers. Flap survival rate was 93.6% (13 leases). On donor site, wound dehiscence, hematoma, sensory change and infection were noted and on recipient site, most common complication were fistula and wound dehiscence. The complication rate of recipient's site was 19.1 % and donor site, 3.5%. In 118 cases (84.3%), the patients could take all kinds of food. Swallowing difficulty were noted in 22 cases 05.7%). In 5 cases, there was articulation difficulty but most of patients except patients having total laryngectomy (18 cases) couldn't have any difficulty in articulation and speaking. Conclusion: We conclude that the radial forearm free flap is the most appropriate reconstructive material for treating the defect in head and neck reconstruction.

With the recent progress of microsurgical techniques, radial forearm free flap has an established place in oral reconstruction. Providing thin, soft and pliable skin with a large and constant vascular pedicle, this flap is optimal for intraoral reconstruction. One of the disadvantages of the flap is donor site morbidity, therefore various methods can be used to reduce it. A male complained of palatal and retromolar area mass with ulceration, which was diagnosed as squamous cell carcinoma. He also complained of discomfort and mouth opening limitation, attributed to the location and characteristics of the mass. Because of mouth opening limitation, mandibular swing approach was performed to allow for the surgical approach to the mass. After the surgical excison of the lesion, the intraoral defect was successfully reconstructed with radial forearm free flap.

The purpose of this study was to determine the efficacy of electrode placement on procaine iontophoresis. Thirty-three healthy students with an age range of 19 to 34 years, were participated in this study. The subjects were randomly assigned into 3 groups. Each subjects received iontophoresis on the proximal 1/3 of volar surface of dominant forearm with soft cotton pad($3.5{\times}3.5cm$) soaked in 2 ml of 4% procaine hydrochloride (pH 5.1) at 4 mA for 10 minutes(total current 40 mA min) of anodal DC. In transversal electrode placement(TEP) group, dispersive electrode was placed on the proximal 1/3 of dorsal surface of the forearm. In longitudinal electrode placement (LEP) group and control group, dispersive electrode were placed on the distal 1/3 of volar surface of the forearm. After procaine iontophoresis, duration of anesthesia were evaluated at five minutes intervals on five random locations in the iontophoretically area using a 21-gauge sterile hypodermic needle pressed with 1 mm invagination until return the sharp pin-pricking pain sensation. The data were ana lysed with one-way ANOVA to determine signific~nt differences between groups. The results showed significantly differences in the local anesthetic duration between the 3 groups(p<0.001). The anesthetic durations of TEP group and LEP group were significantly longer when compared with control group(p<0.05). Anesthetic durations of TEP group and LEP group were not significantly difference, but anesthetic duration of LEP group tends to longer than TEP group. In view of these results, clinicians should consider the electrode placement method when performing the iontophoresis.

Purpose: A palatal defect following maxillectomy can cause multiple problems like the rhinolalia, leakage of foods into the nasal cavity, and hypernasality. Use of a prosthetic is the preferred method for obturating a palate defect, but for rehabilitating palatal function, prosthetics have many shortcomings. In a small defect, local flap is a useful method, however, the size of flap which can be elevated is limited. In 12 cases of palatomaxillary defect, we used various microvascular free flaps in reconstructing the palate and obtained good functional results. Method: Between 1990 and 2004, 12 patients underwent free flap operation after head and neck cancer ablation, and were reviewed retrospectively. Among the 12 free flaps, 6 were latissimus dorsi myocutaneous flaps, 3 rectus abdominis myocutaneous flaps, and 3 radial forearm flaps. Result: All microvascular flap surgery was successful. Mean follow up time was 8 months and after the follow up time all patients reported satisfactory speech and swallowing. Wound dehiscence was observed in 4 cases, ptosis was in 1 case and fistula was in 1 case, however, rhinolalia, leakage of food, or swallowing difficultly was not reported in the 12 cases. Conclusion: We used various microvascular flaps for palatomaxillary reconstruction. For 3-dimensional flap needs, we used the latissimus dorsi myocutaneous flap to obtain enough volume for filling the defect. Two-dimensional flaps were designed with latissimus dorsi myocutaneous flap, rectus abdominis flap and radial forearm flap. For cases with palatal defect only, we used the radial forearm flap. In palatomaxillary reconstruction, we can choose various free flap techniques according to the number of skin paddles and flap volume needed.

Intravascular papillary endothelial hyperplasia (IPEH, Masson's hemangioma) is a non neoplastic reactive endothelial proliferation most commonly located in the skin or subcutaneous tissues although it has been reported in multiple locations throughout the body. This lesion may arise from malformed or normal vessels primarily, and may develop with hemangioma, pyogenic granuloma, or lymphangioma. This lesion, though benign, is clinically important since it may present as a mass and be confused histologically with angiosarcoma. The authors report a 27 years old patient with a mass in his forearm which results in intravascular papillary endothelial hyperplasia.

[ $\alpha$ ]-Terpinene has been known as a repellent against the mosquito Culex pipiens pallens Coquillett based on a human forearm bioassay. $\alpha$-Terpinene showed significantly greater repellency than a commercial formulation, N, N-diethyl-m-methylbenzamide (deet). In this study, skin and eye sensitivity of $\alpha$-terpinene (2%) was examined with bioassays using white New Zealand rabbits. There were somewhat gross and histological changes observed in these treatments. Eye irritancy assays examined gross changes to cornea, iris and conjuctiva, and histological changes to smear of ocular discharge and eye tissue. Treated rabbits were divided into two cohorts, a saline washed cohort (W) or a non-washed cohort (NW). Opacity of cornea and redness, chemosis and discharge of conjuctiva were observed in both cohorts, but disappeared within 4 and 10 days in W and NW, respectively. Main components of ocular discharges were fibrin, epithelial or epitheloid cells, lymphoid cells, erythrocytes and granulocytes. These abnormal cellular components disappeared within 4 days and 10 days in W and NW, respectively. No permanent histological differences were observed between the two cohorts. However, severe irritation was determined as 57.2 of I.I.O.I value on the first day after treatment. These findings indicate a spray-type solution containing 2% $\alpha$-terpinene may serve as an alternative mosquito repellent and further studies need to reduce the eye irritation with formulation changes.
