BACKGROUND: Cosmetics are one of the common causes of contact dermatitis and many new cosmetic products are being introduced rapidly into our market. OBJECTIVE: Our purpose was to investigate the as is patch test result by several factors including age, cosmetic product and atopic diseases, and to compare as is patch result with those of standard and cosmetic patch tests. METHODS: The records of 240 patients were reviewed who had been patch tested with their own cosmetics and toiletries with a clinical impression of cosmetic contact dermatitis at the patch clinic of Kangnam St. Mary's Hospital in the period of 1991-1995. RESULTS: Of the 95 patients who were tested with European standard series 54 (56.8%) showed a positive reaction and nickel sulfate was the most common allergen. Eighteen (38.3%) of the 47 patients tested with a cosmetic series revealed a positive reaction and imidazolidinyl urea and dodecyl gallate were the most common allergens. In as is patch test, 99 (41.3%) of the 240 patients showed a positive reaction to 248 (7.3%) of the 3403 cosmetics. Common cosmetic products showing positive reactions were skin care products (26.2%), face make-ups (19.8%), and hair preparations (16.9%). There was no statistically significant difference in the positive reaction rate between atopy and non-atopy patients. The positive correlation rate of as is test with standard and cosmetic series was relatively low. CONCLUSION: Commercial standard patch test series including cosmetic series are not enough to detect causative allergen in cosmetic contact dermatitis. As is patch test should be encouraged to detect new allergens, because many cosmetic ingredients are developed and introduced in market.

OBJECTIVE: In the development of squamous neoplasia of the uterine cervix, high risk HPV infection has been followed by CD44 variant expression and angiogenesis. The aim of this study is to evaluate the sequential changes and relatianship of CD44 variant expression, microvessel density (MVD), and VEGF expression in CIN III, microinvasive (MI) and invasive (CA) squamous cell carcinoma. METHODS: The materials were 17 cases of CIN III, 14 cases of MI and 15 cases of CA. In situ PCR for HPV 16/18 and immunohistochemical studies for CD44std, v6, v7/8, CD 31 for MVD, and VEGF were performed. RESULTS: CD44std expression was decreased in squarnous neoplasia compared to normal, and CD44v6 and v7/8 expressions were increased, however, there was no statistical significance. Accentuated staining of CD44v6 and v7/8 along the infiltrating borders was noted in 76.9% and 69.2% of MI and in 71.4% and 42.9% of CA, respectively. High MVD and VEGF 2+ expression were higher in the squamous neoplasia compared to narmal, however, there was no significant difference between the squamous neoplasia and no significant relationship between MVD and VEGF expression. The expression rates of CD44std and CD44v6 were higher in HPV 16/18 negative squamous neoplasia and that of CD44v7/8 was higher in HPV 16/18 pasitive squamous neoplasia, however, their differences were not significant. The incidences of high MVD and VEGF 2+ expression were higher in HPV 16/18 positive suqmaous neoplasia with no statistical significance. CONCLUSIONS: These results suggest that CD44 variants expression and angiogenesis are involved in the development of squamous neoplasia of the uterine cervix, however, HPV 16/18 might not be related to CD44 variant expression and angiogenesis.

100% sulfur hexafluoride(SF6) was injected into the vitreous cavity of nonvitrectomized retinal detachment patients. A total of 0.5ml of gas was injected with a single shot in 3 eyes or two 0.25ml in 3 eyes without lowering of intraocular pressure. And in 3 eyes, single shot of 0.5ml of gas was used after lowering of intraocular pressure. The changes of intraocular pressure were monitored at 5 minute intervals for 60 minutes and at one hour intervals for 8 hours after injection. Marked elevation of intraocular pressure was noted in both single shot group, but the elevation of intraocular pressure of double shot group was much smaller. But in all groups, the intraocular pressures were returned to under 30mmHg within 20 minutes and no re-elevation of intraocular pressure was noted in all cases after initial return to normal. In a case with two 0.3ml shots, the highest pressure was 49mmHg and with 0.35ml shots, the highest pressure was 78mmHg. So the effect of SF6 on intraocular pressure seemed to be negligible so long as the injection volume was limited to 0.5ml or less in single shot; and 0.6ml in double shots.

Chronic central serous chorioretinopathy[CSC], which also has been termed diffuse retinal pigment epitheliopathy, is defined as a sensory retinal detachment associated with areas of RPE atrophy and pigment mottling. Fluorescein angiographic finding includes areas of granular hyperfluo-rescence and one or many subtle leaks. In older age group, choroidal neo-vascularization[CNV]may develop as a complication. We investigated the clinical features and performed fluorescein angiography[FAG], indocyanine green[ICG]angiography in 10 patients with CNV among 32 patients with chronic CSC. The location of CNV was extrafoveal[3 eyes]and juxtafoveal[7 eyes]. Associated fundus findings were RPE atrophy[8 eyes], PED[5 eyes], serous RD[4 eyes], subretinal hemorrhage[4eyes]. ICG findings were hypo-fluorescence[8 eyes], choroidal hyperpermeability[7 eyes], choroidal delayed filling[5 eyes]. Choroidal neovascularization was identified only with ICG angiography in 6 out of 10 cases. Laser photocoagulation was performed using ICG angiography in 6 cases. Visual acuity was improved in 4 out of 10 cases, and unchanged in 3 out of 10 cases. Therefore, we suggest that ICG angiography may be used as an important device for the diagnosis and management of CNV in patients with chronic CSC. Visual prognosis of CNV in chronic CSC seems to be relatively good.

The ankle joint is a modified complex hinge joint which plays an important role in weight bearing, walking and standing. Hence, the ankle injuries include not only fractures of bone but often also the rupture of ligaments and soft tissues, so if the structures were not accurately repaired, many complications may be developed. The authors have reviewed a series of 70 cases of ankle fractures which were treated in department of orthopaedic surgery of Inha hospital from January 1988 to February 1992. Among the seventy cases, 41 patients (59.4%) were male, and 28 patients (40.6%) were female. Average age was 41.4 years and 3 cases (4.35%) were open fracture. The most common cause was slipping 34 cases (48.6%) and the other causes were traffic accident 23 cases (32.9%), fall from height 6 cases (8.6%), direct blow 5 cases (7.0%) and sports injury 2 cases (2.9%) in order. The rusults obtained form this study were as follows. l. According to the classification fo Lauge-Hansen, the most common fracture mechanism was supination-external rotation injury (24 cases: 34.4%). 2. Among them, 51 cases were treated by operative treatment and 19 cases by conservative treatment. 3. Ten cases (14.3%) in this series were complicated; traumatic arthritis in 7 cases, infection in 2 cases and nonunion 1 case. 4. Open reduction and internal fixation and early anatomical reduction were better than closed reduction and delayed reduction. 5. The incidence of traumatic arthritis occured higher in the cases treated with closed method.

Intertrochanteric fractures of femur were increasing in their incidence in morden life. The compression hip screw and Ender nail are popular treatment modalities of the interochanteric fracture of femur. We had tried to clarify the complications of intertrochanteric fracture according to the treatment modality-compression hip screw and Ender nail. We obtained the results as followings with the patients who had intertrochanteric fracture of femur which were managed by compression hip screw (56 cases) and Ender nail (22 cases) through the period of March 1987 to June 1993. The summary of the results; 1. Mechanical complications were developed in 9 patients(16%), 9 complications in the group with compression hip screw and 7 patients(32%), 12 complications in Ender nail. 2. Local complications were developed in 4 patients(7%) in compression hip screw and 10 patients (46%) in Ender nail and the most common local complication was the knee joint pain(7 patients; 32%). 3. Statistically, more significant decrease of neck-shaft angle was shown with group using Ender nail for unstable fracture than stable fracture group and compression hip screw group. 4. The degree of shortening was incrased in group with Ender nail than in group with compression hip screw, but there was no statistical significance. 5. The grade of osteoporosis was not related to the change of neck-shaft angle and shortening and also to the development of mechanical complication. According to the above results, compression hip screw was a more stable fixation device than Ender nail in the unstable intertrochanteric fracutre.
