BACKGROUND: Redundant and wrinkled face is a common finding in patients with long-standing leprosy, which is responsible for the appearance of premature aging. Chemical peeling plays a role in dermal regeneration in the treatment of wrinkles. However, the effect of chemical peeling has rarely been studied in patients with leprosy. OBJECTIVE: To investigate the effect of chemical peeling on dermal connective tissue components and clinical improvement of facial wrinkles in patients with leprosy. METHODS: Five patients with clinically and bacteriologically inactive lepromatous leprosy were treated with 70% glycolic acid plus 35% trichloroacetic acid (GA-TCA). Histologic and clinical changes were evaluated at 0 and 90 days postpeel. RESULTS: Histologically, collagen fibers and ground substance increased significantly but elastic fibers did not change at 90 days postepeel. Clinically, fine wrinkles improved considerably, whereas most deep wrinkles remained unchanged at day 90. CONCLUSION: This study demonstrates that chemical peeling with GA-TCA, or medium-depth peeling, causes an increase in collagen and ground substance but not in elastic fibers. These changes result in limited clinical improvement in the facial wrinkles of leprosy patients. Therefore, medium-depth chemical peeling may be insufficient to improve the premature aging appearance in patients with leprosy.

PURPOSE: The purpose of this research was to provide baseline data by utilizing solutions to health problems caused by work-related stress and to examine a way of treatment by comparing and analyzing how the stresses link to fatigue and quality of researchers' life. METHODS: A survey was conducted with 50 researchers working for in H research institute in Daejeon Metropolitan City from April 10th to May 10th, 2012 to examine the correlation of work stress, fatigue and quality of life. The data were analyzed using the Kruskal-Wallis test to look into examine the difference in work stress, fatigue, and quality of life. Also, the correlation of work stress, fatigue and quality of life was measured through by the Pearson correlation coefficient. The data collected through the questionnaires was were analyzed by SPSS 21.0 based on the significant level with a p-value, 0.05. RESULTS: The results showed that fatigue was caused by work stresses in researchers and quality of life was ranked in a relatively low level. Correlation of work stresses, quality of life and fatigue and work stresses against mental health index was negative and fatigue against physical index was also negative. CONCLUSION: It is necessary to maintain more detailed provisions in order to improve mental health and stress level of researchers. Moreover, systematic, in-depth evaluation should be done to reduce researcher's work-related stress and fatigue. In addition, stress management and prevention program should be implemented for these researchers.

PURPOSES: To demonstrate changes in urinary biochemistry that lead to a supersaturation of some salt, which makes a higher prevalence of urinary stone in workers chronically exposed to a hot environment and massive sweating. MATERIALS AND METHODS: The study was performed at a metal plant and exposure to heat stress was estimated by the Wet Bulb Globe Temperature climatic index. Stone risk profile from our laboratory included volume, specific gravity, creatinine, sodium, potassium, calcium, magnesium, chloride, uric acid, phosphorus and pH. On a randomly selected sample of 19 workers exposed and 19 workers not exposed to heat stress without any evidence of stone disease, and family history of nephrolithiasis or predisposing factors such as gout, we performed a stone risk profile by collecting the urine during the 8-hour work shift for 1 consecutive days. The independent student t-test was used to compare each parameter between the different groups. RESULTS: Among a randomly selected urine sample of 19 workers exposed and 19 workers not exposed to heat stress without any evidence of stone disease, significant differences were found in fluid intake (2816.0+/-1981.0 ml. versus 1200.0+/-4147.0), and concentration of creatinine (1481.0+/-691.0 ml./l. versus 1032.0+/-574.0), sodium (201.0+/-55.0 mg./l. versus 147.4+/-58.0), calcium (202.0+/-76.0 mg./l. versus 132.0+/-71.0), uric acid (475.0+/-138.0 mg./l. versus 359.0+/-196.0), phosphorus (638.0+/-283.0 mg./l. versus 328.0+/-196.0), pH(6.05+/-0.61 versus 6.72+/-0.92), specific gravity(1.029+/-0.005 versus 1.014+/-0.006) respectively. CONCLUSIONS: This study confirms the concept that heat stress represents a real lithogenic risk factors. Therefore, we recommend adequate fluid intake during hot occupations.

BACKGROUND: Ulnar nerve palsy in patients with Hansen disease causes hand wasting and atrophy. To masquerade these deformities, patients injected paraffin or silicone into the lesions, which results in paraffinomas. Several years later, painful inflammation, ulceration or abscesses may develop in the paraffinomas. OBJECTIVE: To investigate the clinical characteristics of paraffinomas in patients with Hansen disease, and to evaluate and compare the effects of various surgical treatment methods of paraffinomas. METHODS: Fifty-seven patients with paraffinomas were randomized to receive debridement(curettage) with primary closure, skin graft, skin flap, or second intention at the hospital of Korean Hansen Welfare Association from 1998 to 2012. We analyzed retrospectively the final cosmetic results of three methods, primary closure, skin graft, and skin flap, in 33 patients with more than 6 months follow-up. The final results were classified into 4 grades, excellent, good, fair, and poor. RESULTS: Of 57 patients, the ratio of male and female was 42:15 and the average age was 73 and 71 years repectively. The location of the lesions was the hand and wrist in 54 patients and the face in 3. The total number of procedures was 72 and that of 3 methods was 55. In 33 patients, 19 showed above fair grades and the recurrence rate was 42%(14/33). There were no serious postoperative complications. CONCLUSION: Wide and thorough curettage as debridement was very important to reduce recurrence and the primary closure was most efficient in consideration of an old age of patient, simplicity of procedure and cosmeosis.

Lepra bacilli invade the nasal mucosa from early stage. The infiltrated mucous membrane breaks down and ulcerates easily. Irritating crusts and ulcers occur, creating in perforation of the septum. When most of the septum and inner mucosal lining of the nose is destroyed, the nose is deprived of its support and it collapses. The nasal bones are typically intact, and the collapsed nose adheres to the facial skeleton, giving the characteristic 'sunken and short nose' deformities. We have operated on 25 patients with deformities such as short nose, sunken nose, collumela deformity and ala collapse since 1992. In short nose we operated with a paramedian forehead flap and rib cartilage graft in a cantilever pattern. In ala collapse we used a conchal cartilage graft. Lastly, in collumela deformity we used the local flap and a composite graft.

BACKGROUND: Damage of the facial nerve, especially buccal and marginal mandibular branches, causes facial palsy and paralytic deformity of the lips such as lower lip ectropion, lip drooping, deviation of the mouth, inability of closing mouth, and the loss of the nasolabial folds. OBJECTIVE: To find out the best surgical method to correct paralytic deformity of the lips. METHODS: We reviewed retrospectively the various surgical treatment modalities of the paralytic deformity of the lips performed in The Institute for Leprosy Research for 13 years. RESULTS: One hundred and twenty five surgical procedures were performed in 80 patients with Hansen's disease. Of these, the static method, dermal suspension flap, was done in 15 cases, the dynamic methods were done in 64 cases, and others were done in 46 cases. All patients showed postoperatively clinical improvement above the average. Two patients received reoperation or additional procedures due to relapse of the condition. CONCLUSIONS: The dynamic method using tensor fascia lata was superior to other treatment modalities.

Facial nerve paralysis in leprosy adversely affects facial regions from the forehead to the lip. In particular, lagophthalmos in patients with leprosy causes exposure keratitis, corneal and conjunctival dryness which can progress blindness and disfigurement. The function of the eyelids is controlled by the oculomotor nerve and the facial nerve. In leprosy patients the oculomotor nerve continues to function causing the levator muscle to lift the eyelids. However, paralysis of the facial nerve prevents the orbicularis oculi muscle from closing the eyelids, resulting in lagophthalmos. Various methods were developed to correct lagophthalmos, one of which was temporal muscle transfer(TMT) reported in 1934 by Gillies. Since we noted relatively high occurrence of ptosis as a complication in patients treated previously with the TMT, we performed other surgical procedures for laglphthalmos over 15 years, not to make the ptosis. Although most of the patients quite improved post-operatively, partial lid-gap frequently persisted. It may be related to involutional changes and paralyzed orbicularis muscle. Recently, we conducted 4 different TMT methods for last 4 years to reduce ptosis. The methods used included Brown & McDowell, McCord & Codner, modified Gillies & Anderson, and modified Gillies. Seventy-five TMT operations in 60 patients(26 males and 34 females) were done between 2011 and 2014. The age range of the patients was 54~87 years(the mean was 70.1). Fifteen patients had bilateral TMT procedures. As a result, ptosis appeared in 14(18.7%) out of 75 TMT procedures for 4 years. Four technical points should be considered for the initial assessment to prevent or reduce the incidence of ptosis. The first is the increase of the length of temporalis muscle flap to approximately 8cm with a parallel course to the lateral canthus, which will reduce the oblique pull. Second, the width of the fascia sling in the upper eyelid is narrow(3~4mm) to reduce weight on the eyelid. Third, the fascia sling in the upper lid is not tied with that of the lower lid at the medial canthal tendon to reduce tension. Lastly, the fascia sling in the upper eyelid is shallow(subdermal level) in location and as near as possible to the lid margin.

Paralytic lagophthalmos and ectropion in leprosy are serious complications of facial paralysis, which may lead to expose keratitis, corneal ulceration, further lead to blindness. In 1995, 1997 and 1999, we had reported in this journal on the surgical treatment of paralytic lagophthalmos and ectropion. In the first report of 1995 for lid closing, I(Ahn) performed various method of traditional surgery such as temporal muscle transfer, medial and lateral canthoplasty as well as gold implantation. In the 2nd report of 1997, We(Ahn and Park) presented combination treatment of gold plate with minor change of design and weight in the upper lid and medial canthoplasty with horizontal shortening in the lower lid. In the 3rd report of 1999, We described an additional graft of conchal cartilage in the lower lid. However, the lateral end of the cartilage would warp and create new partial ectropion several months later. Therfore, we shifted from cartilage to Alloderm(R), acellular dermal graft. We applied it to the lower border of the tarsus instead of cartilage and fixed each end to medial and lateral canthal ligaments respectively. We think Alloderm(R) is a good substitute for the cartilage and is an effective volume expander to the atrophic lower lid.
