BACKGROUND: Squamous cell carcinoma(SCC) is one of the most conimon forms of skin cancer that arises from the surface epidermis. Although many authors have reported on the incidence and clinical features of SCC, we could not find any reports concerning the widerange of histopathologic features of a number of cases of SCC in Korean dermatologic literature. OBJECTIVE: We examined the histopathologic features of SCC. METHOD: Twenty six biopsy specimens from 26 patients with SCC were examined microscopically including the tumors themselves and surrounding epidermis and dermis on routine histologic staining. RESULTS: Grade 1 tumor was found in 15 cases, grade 2 in 8 casese, and grade 3 in 3 cases. Eighteen cases showed keratin pearls, and 11 cases showed squamous eddies. P cantholysis of tumor cells was found in all 26 cases, but glandular structure was found only in 5 cases. The epidermis overlying the tumor showed hyperkeratosis and parakeratosis in all 26 cases, follicular plug in 13 cases, and ulceration in 18 cases. The dermis beneath the tumor showed vessel dilataticn, hemorrhage, and infiltration of inflammatory cells in all 26 cases, and basophilic degeneration in 1.3 cases, fibrosis in 20 cases, lichenoid reaction in 6 cases, and necrosis in 6 cases. Rare dermal findings were abscess, foreign body reaction calcification and Russell body. CONCLUSION: The histopathologic findings of SCC were variable not inly those of the tumors themselves, but also those of the surrounding epidermis and dermis.

A sensitive thermometer utilizing thermistor as a sensing element has been constructed in order to measure the temperatures in various ocular tissues. The Wheatstone bridge was used to detect the changes in thermistor resistance. The out-put of the bridge was fed into a single-stage differential DC amplifier and read by an micro-ammeter. There was a linear relationship between temperature and meter scale. The thermistor was inserted into the inferior conjunctival sacs of 158 healthy normal human eyes. The average temperature was found to be 35.14 +/- 1.08 (in C). No difference due to sex and age distribution was found to exists. Preliminary temperature measurement has been done on rabbits. Their results are shown graphically in Fig. 3.

PURPOSE: Kawasaki Disease(KD) is a febrile disease with acute multisystemic vasculitis associated with early development of acute myocarditis and coronary artery abnormalities. The cause and etiologic agents are still unknown. Clinical studies suggest that KD is one of the autoimmune disorders caused by infectious agent, but this is not proved yet. The study was performed to investigate the levels of vascular endothelial growth factor(VEGF) in the acute stage of KD before treatment of intravenous-gammaglobulin(IVGG) to confirm and find an early diagnostic method of vasculitis by serologic test. METHODS: The patient group consisted of 61 cases in acute stages of KD before treatment of IVGG who were hospitalized from Jan. 1998 to Feb. 2001. The control group consisted of 24 cases among the admitted cases who suffered from non KD. The levels of VEGF in the obtained sera were measured by using chemoluminoimmunoassay, and those of both groups were compared to each other. RESULTS: The sex ratio of male to female was 1.6:1, males were more prone to infection, and mean age was 2.6+/-1.6 years old. The levels of VEGF in patients group(143.64+/-115.38 pg/mL) were significantly increased as compared with control group(26.55+/-13.75 pg/mL)(P<0.05). One case of acute myocarditis and two cases of left coronary artery dilations occurred in the patient group, but they all recovered after treatment two months later. Acute phage reactants such as CRP, ESR were positive and WBC was increased in acute stages of both groups. CONCLUSION: The significant increasing level of serum VEGF in acute febrile stages of KD suggests that acute vasculitis began in the early stage in all of the patients group, and the measurement of VEGF can be one of useful method for early diagnosis of vasculitis in KD. This may be helpful in early IVGG treatment of the condition.

PURPOSE: To recommend optimal surgical techniques in cases of remaining anterior instability after Bankart repair, according to the amount of remaning labrum. MATERIALS AND METHODS: Between December 1996 and April 1999, we experienced 27 pateints that have undergone arthroscopy for recurrent shoulder dislocation. They were followed over 1 year (1 year to 3 year 2 months) and classified into three groups: Group I (Arthroscopic Bankart repair by transglenoid technique); 9 cases, Group II (Arthroscopic Bankart repair by suture anchor); 11 cases, Group III (Arthroscopic Bankart repair by transglenoid technique with suture anchor); 7 cases. RESULTS: A significant difference was found between Group I and Group III patients with poor or no remaining labrum, especially in teims of shoulder stability and range of motion recovery. CONCLUSION: Arthroscopic Bankart repair by suture anchor in a shoulder that has good labrum produced a good result. However, in a shoulder with poor labrum, the combination method of transglenoid technique with suture anchor should be considered to reduce recurrency.

PURPOSE: The study was performed to investigate the IgG subclasses in acute febrile phase of Kawasaki disease(KD) to find correlation between selective IgG4 deficiency and incidence of KD patients. METHODS: The patients group consisted of 64 cases in acute phase of KD hospitalized from Jan. 1996 to Jul. 1999, and control group consisted of age matched 36 cases who admitted without KD. The obtained sera were measured the level of total IgG, IgM, IgA and IgG subclasses(IgG1, IgG2, IgG3, IgG4) by using Enzyme Immuno Assay and Single Radial Immuno-Diffusion method. RESULTS: The sex ratio of male to female was 1.4:1.0, and febrile days before admission was 4.6+/-2.4 days. Total levels of IgG, IgM and IgA were normal range in both groups. The levels of IgG1, IgG2 and IgG3 were not specific changes but significantly decreased the level of IgG4 in patients group as compared with control group(P<0.05). CONCLUSION: Selective decreased the levels of serum IgG4 can be one of factors to increasing the incidence of KD.
