BACKGROUND: Excessive sweating, especially of the palms, soles and axillae, is a socially and an occupationally distressing, and sometimes disabling condition. A variety of treatment methods are used to reduce profuse sweating including topical agents, iontophoresis and symphatectomy. OBJECTIVE: We investigated whether a 20% aluminum chloride solution is efficient in the treatment of axillary and palmoplantar hyperhidrosis using a skin surface hydrometer. METHODS: We treated 31 patients (7; male, 24; female) by Drysol once a day at bedtime for four weeks. We had measured the conductances on the stratum corneum of the palms, soles and axillae using a skin surface hydrometer before and after treatment every week for four week RESULTS: There was a reduction of conductances after the treatment by Drysol (p<0.05). The reduction of conductances was continued for four weeks (p<0.05). CONCLUSION: Drysol is an efficient, safe, and simple method for initial treatment of the primary hyperhidrosis.

Keratosis lichenoides chronica is rare chronic dermatosis characterized by progressive development of licheniod papulonodules especially on the extremities and trunk. A 15-year-old male patient had erythematous to violaceous scaly patches and plaques on the left side of trunk and lower extremity along Blaschko's lines. Clinical and histologic findings were compatible with keratosis lichenoides chronica showing unilateral distribution.

A comparison betwen electrocardiographic and echocardiographic criteria of Lt. atrial enlargement was made in 40 cases who demonstrated left atrial enlargement either electrocardiographically or echocardiographically. 1) There were 20 cases with Lt. atrial enlargement by electrocardiographic criteria and echocardiographic criteria and 30 cases by echocardiographic criteria 2) Of 40 subjects, 19 cases were found to satisfy both electrocardiographic and echocardiographic critera of Lt. atrial enlargement at the same time. 3) 10 cases were consistent only with electrocardiographic criteria of Lt. atrial enlargement, but not with echocardiographic criteria 4) On the other hand, 11 cases of Lt. atrial enlargement consistent with echocardiographic criteria did not meet the electrocardiographic criteria 5) The respective predictive indices of electrocardiographic and echocardiographic criteria of Lt. atrial enlargement were: Electrocardiographic criteria; positive: 65.52%, Negative: 79.9%. Echocardiographic criteria; Positive: 63.3%, Negative: 89.13%.

BACKGROUND: Primary hyperhidrosis is the disease of production of exessive sweat which is mainly localized in palm, sole, and axilla, treatment of the disease is usually accomplished with topical 20% aluminum chloride solution, an iontophoretic device, and surgery(sympathectomy) being reserved for recalcitrant cases. OBJECTIVE: We have compared the therapeutic effects with each treatments for hyperhidrosis using a skin surface hydrometer. METHODS: Thirty six patients(11 ; male, 25 ; femlale) with primary hyperhidrosis were evaluated in this study. Nineteen patients used topical 20% aluminum chloride solution, 10 patients used iontophoretic device, and 7 patients in recalcitrant cases. had sympathectomy. We have measured the conductance on the stratum corneum of the palm and sole suing skin surface hydrometer before and after treatment every weeks for a month. the control group were composed of healthy 10 males and 2 females. RESULTS: 1) In the patients of primary hyperhidroisis the conductances of palm, sloe and axilla were higher than that of control group(P<0.01). 2. There was a marked reduction of conductance after the treatment for one week by topical 20% aluminum chloride solution, an lontophoretic device, and sympathectomy(P<0.01). 3. After 2-4 week of treatment by the change obsetved after treatment for one week. 4. By iontophoretic device, there was a slight increasement of conductance of the palm after 2-3weeks of treatment. 5. We obseved a sustained decrease in the conductance by sympathectomy into 4 week. CONCLUSION: Topical 20% aluminum chloride solution, iontophoretic device, and sympathectomy were effective for treatment of hyperhirosis. Among hem sympathectomy showed the best effect. We observed that the skin surface hydrometer is useful to evaluate of the efficacy of the treatment.

PURPOSE: To evaluate CT findings of normal anatomic alteration after neck dissection. MATERIALS AND METHODS: The postoperative CT findings were retrospectively reviewed in 40 patients with neck dissection, comparing to preoperative CT. There were 28 patients with radical neck dissection and 12 patients with modified radical neck dissection or selective neck dissection. In addition to the neck dissection, 10 patients had undergone pectoralis major myocutaneous flap reconstruction, 20 patients taken laryngectomy, and 25 patients treated with radiotherapy. RESULTS: The typical CT findings of radical neck dissection were non-visualization of internal jugular vein and sternocleidomastoid muscle(28/28), ipsilateral neck flattening(26/28), and trapezius muscular atrophy(12/28). The other non-specific findings were tissue plane eftacement, subcutaneous reticular pattern, platysma muscle thickening, and adjacent soft tissue contrast enhancement which was the only evidence of previous operation in the cases of modified radical neck dissection or selective neck dissection. Reconstruction with myocutaneous flap was shown as ipsilateral bulk of fat and muscle(10/10). In cases with radiation therapy there was much increased density of submandibular gland(12/25). 15 patients showed recurrence on follow up CT scan, including regional metastasis in 10, stomal recurrence in two, and residual mass at primary site in three patients. CONCLUSION: CT is useful in evaluation of patients with neck dissection and in whom postoperative change impese diagnostic problem.

Many investigators have reported that collagen gel contraction reflects the mechanism of wound contraction. In 1995, Tsai et al. reported that hypertrophic scar-derived fibroblasts in a connective tissue model possessed the greatest contraction potency when compared with those of normal skin and normal oral mucosa-derived CTMs. In this study, we studied the effect of collagen gel contraction by growth factors such as epidermal growth factor, platelet-derived growth factor, transforming growth factor-bata1, and transforming growth factor-bata3, Skin fibroblasts used in this study were obtained from the explant of rat skin culture. Fibroblasts were cultured in Dulbecco's modified Eagle's medium containing 10% fetal bovine serum. Growth factors were added per FPCL in the desired concentrations and we measured the collagen gel diameters in growth factor-treated FPCL on day 1,2,3, and 4 respectively after starting incubation. We examined the effects of EGF, PDGF, TGF-bata1, TGF-bata3 and the effects of combinations of TGF-bata1 + EGF, TGF-bata1 + PDGF, and TGF-bata1 + TGF-bata3 to contract a collagen gel. EGF has little influence on collagen gel contraction. TGF-bata1 and TGF-bata3 increase the collagen contraction. TGF-bata1 enhanced the contractility of collagen gel according to the concentrations. While TGF-bata3 alone had stimulatory contraction effects at low dose, high doses of TGF-bata3 decreased the potency of collagen gel contraction. A combination of TGF-bata1 and EGF minimally decrease TGF-bata1 activity. A combination of TGF-bata1and PDGF had an effect similar to TGF-bata1 activity. A combination of TGF-bata1 and TGF-bata3 decreased TGF-bata1 activity. According to reports that FPCL contraction is equivalent to the process of wound contraction, growth factors which enhance gel contraction may be related to wound contraction and wound healing. TGF-bata1 is reported to enhance scar formation in fetal wound. EGF accelerates wound healing and inhibits the promotion of hypertrophic scar formation. Compared to the effect of collagen gel contraction in this study, the combination of TGF-bata1 and TGF-bata3 that inhibited the promotion of collagen gel contraction are thought to diminish the formation of scar tissue. As well, EGF that has not enhanced collagen gel contraction is thought to diminish the production of scar tissue. We will study the interactive effects of TGF-bata3, EGF and TGF-bata1 on the contraction of collagen gels in the future.
