BACKGROUND: Although the wet earwax has been known to be related with the incidence of tinea versicolor, very little has been revealed on how they are correlated with each other. The incidence of Malassezia furfur, the etiological organism of tinea versicolor, and its population densities as yearst and mycelial form in the different types of earwax, the dry and the wet, have not been studied. METHODS: The type of earwax in 65 patients with tinea versicolor were classified into 2 types, dry and wet, by its appearence and the subjective complaints of the patients. The dry and wet cerumens were obtained from 142 and 49 individulas without tinea versicolor respectively. The cerumens were stained with 10% Parker ink-KOH solution. The incidence and its population densities of yeast and mycelial M. furfur in the wet cerumens were compared with those in the dry cerumens according to a new grading method using bacterial index(BI) of lepra bacilli. RESULTS: 1. Dry and wet earwax were observed in 58.5%(38 cases) and 41.5%(27 cases) of 65 patients respectively. 2. The incidence of yeast M. furfur in the dry and wet cerumens were 100% and 63.3%(31 of 49 cases) respectively, and that of mycelial M. furfur, 28.2%(40 of 142 cases) and 32.7%(16 of 49 cases) respectively. 3. The population densities(from 3+ to 6+) of yeast M. furfur in the dry and wet cerumens were ob served in 93.0%(132 of 142 cases) and 49.0%(24 of 40 cases), and those(3+) of mycelial M. furfur, 21.1%(30 of 142 cases) and 24.5%(12 of 49 cases) respectively. CONCLUSION: The incidence(41.5%) of wet earwax in tinea versicolor patients is significantly higher than that(0.8%) in The Korean control group. The ratio between the incidence of mycelial M. furfur and that of yeast M. furfur in the wet cerumens is higher than in the dry cerumens, and the ratio of population densities in the wet cerumens is also higher. These observations suggest that the skin surface conditions of the wet earwax group may be more suitable for yeast-mycelial transformation of M. furfur than those of the dry earwax group. The comparison of chemical compositions of the skin surface between dry and wet earwax groups is needed to elucidate the correlation between tinea versicolor and the types of earwax in the future.

The status of DNA synthesis and the effect of UV radiation on the DNA synthesis were studied in mouse skin by microautoradiography. Mice exposed to 100mJ/cm of UVB were injected intradermally with tritiated thymidine, 5 minutes, 2, 6 and 24 hours after irradiation and biopsies were processed for light microscopic autoradiography, A total of 25 ICR female albino haired mice were used as subjects. We compared heavily labeled cells(>10 grains/nucleus) and sparsely labeled cells (3-10 grains/nucleus) in UVL irradiated skin with nonirradiated control skin. 1. Within 5 minutes after UVL exposure an apparent depression in the number of heavily labeled cells occurred. This reduction was statistically significant and remained so for at least six hours post,irradiation. By 24 hours after UVL exposure, the reduction was recovered to nearly control level. 2. By five minutes after UVL exposure, sparsely labeled cells were observed in basal cell layer and differentiated cell layer. The nurriber of sparsely labeled cells appeared highest at five minutes after UVL exposure and then tended to fall to nearly control level at 24 hours. This aberrant type of TdR H incorporation is thought to represent unscheduled DNA synthesis to repair pyrimidine dimers formed in UVL injured DNA molecules,

Microsporum ferrugineum was the most common cause of tinea captis in Korea until the middle of the 1970s, but this organism has been only rarely isolated from the scalp ringworm during recent years. We report, three cases of tinea capitis occurring in a 2-year-old male, a 10 year-old female and a 5-year-old male. From all three patients, Microsporum ferrugineum was isolated.

Interlocking nailing technique has many advantages in the fracture treatment. Such as the prevention of infection and devitalization by closed technique, stable intramedullary osteosynthesis, bone grafting effect of reaming debris, and early restoration of loading and function, comparing to the conventional intramedullary nailing. However, we met many problems during the operative procedure due to deficient concept and technique. We have checked the possible problems during and after the procedure of interlocking nailing for the tibia or femur fractures in 69 cases. 1. Sixty nine cases were consisted by 26 cases of femur fractures and 43 cases of tibia fractures. 2. The inadequate implant length was the most common error in the implant selection (4 cases in femur, 6 cases in tibia). 3. A new fragment was made in 12 patients(17%) during surgery, more commonly in the femur (9 cases), especially medial side and distal to the fracture line. 4. Bone shortening, angulation deformity or rotational deformity, caused by incomplete reduction, were developed more commonly in the tibia than in the femur. 5. Post-operative deep infection were developed in 2 cases(3%). 6. Delayed or non-union were developed in 18 cases(28%), who were followed for more than 3 months. 7. Circumferential wiring or bone grafting using semiclosed technique is thought to be useful to prevent delayed or nonunion when there is a wide gap between fractured fragments pre-operatively.

Nevus sebaceus of Jadassohn is a hamartoma of the skin with the potential to develop benign and malignant neoplasms. This case was characterixed by multiple basal cell epitheliomas, clinically one reddish nodule and multiple pigmented papules, arising in the nevus sebaceus. Histologically, epithelial papillomatous hyperplasia and high-positioned hyperplastic sebaceous glands were found, and tumor nests consisting of basaloid cells with peripheral palisading arrangements were mainly situated in the upper dermis without significant infiltrative growth. We report a rare case of nevus sebaceus with multiple basal cell epitheliomas in the right cheek of a 49-year-old woman.

BACKGROUND: To report the radiological and clinical outcomes of internal fixation using distal clavicle hook plates for distal clavicle fractures. METHODS: From April 2008 to December 2012, 32 patients with distal clavicle fractures underwent surgery using an AO hook plate. The reduction was qualified and evaluated according to the radiological findings. The evaluation of the clinical outcomes was performed with the University of California at Los Angeles (UCLA) score, the Korean Shoulder score, and the visual analogue scale (VAS) pain score. RESULTS: By radiological evaluation, we found that 31 of 32 patients showed anatomical reduction and solid bone union. Although we obtained satisfactory UCLA scores, Korean Shoulder Scale scores, and VAS pain scores, 12 cases of complications were present. We found 4 cases of osteolysis of the acromion, 1 case of nonunion, 3 cases of periprosthetic fractures, 3 cases of subacromial pain, and 1 case of skin irritation. We performed re-operations in 2 patients. CONCLUSIONS: To avoid complications associated with clavicle hook plates, choosing the appropriate hook size and bending of the hook according to the slope of the acromion undersurface is critical. Also, we believe that early removal of clavicle plates may help reduce complications.

BACKGROUND: Previous studies indicated that there was important correlation between early patency of infarct-related artery, preservation of ventricular function, and improved survival after thrombolytic therapy for acute myocardial infarction. An increased infusion rate of rt-PA has been shown to result in faster thrombolysis and a high patency rate of occluded vessel in myocardial infarction. Therefore, we evaluated the effect of simplified triple bolus injection of rt-PA on early patency of infarct-related artery and evaluated safety and efficacy of triple bolus injection. METHOD: Patients with acute myocardial infarction presenting up to 6 hour from the onset of chest pain were recruited for the study. Aspring(100-200mg) was given immediately. Total dose for 1.5mg/kg of rt-PA(minimum 75mg, maximum 100mg) was administered as triple bolus intravenous injections. The half of total dose was injected initially, the quarter of total dose was injected at 10 minutes after 1st injection and the remainder was injected at 40 minutes after 1st injection. Five thousand units of heparin was given and 1,000-1,500unit/hr was given continuously. Coronary angiogram was performed at 60 minutes and 7-10 days after the first bolus injection. RESULTS: At 60 minutes, eleven of fourteen patients (78.6%) showed TMI grade-3 of patency in infarct-related coronary artery. There were two patients of hemorrhagic complications. One patient developed cerebellar hemorrhage at third day after rt-PA injection, and the other developed bleeding at femoral sheath site. There was no in-hospital mortality and reinfarction. CONCLUSION: In patients with acute myocardial infarction, the simplified triple bolus injection of rt-PA is associated with high early patency(TMI grade-3) in infarct-related coronary artery, with low risk of major bleeding comlications comparable to other studies.
