In the study of 142 psoriatic patients who visited psoriasis clinic in Seoul Nstional University Hospital during recent five years, psoriasis was classified according to the severity based on the activity. The guideline of activity was as follows : 1. Mild: skin lesions stationary for the last one month. 2. Moderate : peripherally spreading plaque lesions with only occasionally small papules. 3. Severe : rapidly developing new lesions from the periphery of plaques or normal skin, or newly developing pustules. This study was done to evaluate the distribution and clinical features of psoriasis according to the activity. Among 142 patients of psoriasis, 84(59.2%) patients had mild psoriasis, 39(27. 4%) patients had moderate psoriasis, and 19(13.4%) patients were presented as severe psoriasis.

This study was undertaken to investigate the efficacy of 5% PABA cream using mouse ear swelling reaction(ESR). Mice were exposed to 100mJ/cm of UVB, five times a week for four weeks, on the both ventral aspect of the ear, with application of 5% PABA cream on the right ear. The results were as follows : 1. The intensity of ear swelling reaction of 5% PABA protected group was reduced greater than unproteeted group after the first 3 days of UUR. 2. The intensity of ear swelling reached at peak after 1 week of the ultraviolet radiation. Thereafter it has decreased gradually the following 4 weeks. The difference of ear swelling between the two groups was the greatest after 1 week, and the sunscreening efficacy of 5% PABA cream has remained persisted for 4 weeks. 3. The number of mice which have shown severe inflarnmatory response after ultravioiet radiation was more in unprotected group than that in 5% PABA protected group. 4. Determination of mouse ESR is considered a good method for the evaluation of longterm efficacy of sunscreen preparation.

Purpose: This study investigated the incidence and risk factors of cataract in people with diabetes mellitus (DM) using data from Ansan cohort of the Korean Genome and Epidemiology Study (KoGES). Methods: Data from a total of 329 patients with type 2 DM without cataract who participated in Ansan cohort of the KoGES from baseline survey (2001–2002) to fifth follow-up visit (2011–2012) were examined.The characteristics of the subjects were analyzed with frequency and percentage, and mean and standard deviation. Cataract incidence was measured as incidence proportion (%). For risk factors of cataract, hazard ratio (HR) and 95% confidence interval (CI) were obtained using the Cox proportional hazard model. Results: The cataract incidence over a 10-year follow-up period was 19.1% (15.1 in males and 25.8 in females), and mean age at the incidence of cataract was 63.48 years (61.58 years in males and 65.31 years in females). Age (HR=1.09, 95% CI=1.05–1.13) and HbA1c (HR=1.21, 95% CI=1.07–1.37) or the duration of DM (HR=1.05, 95% CI=1.00–1.09) were found to be independently associated with cataract development. Conclusion Cataract development in people with DM is common, and its likelihood increases with age, HbA1c, and the duration of DM. Considering negative effect of cataract on their quality of life and economic burden, nurses should identify people with DM at a higher risk of cataract development, and plan individual eye examination programs to detect cataract development as early as possible.

PURPOSE: To correlate SOhographic and pathologic findings of gallbladder adenoma, and to evaluate the clinical significance of sonographic findings. MATERIALS AND METHODS: Ultrasound findings of twenty gallbladder adenomas were retrospectively reviewed to evaluate the size, shape and echogenicity of the adenoma, and was correlated with the pathological finding. RESULTS: Among 14 patients, 11 patients had single lesion and 3 patients had multiple lesions. Three patients showed 2, 3 and 4 adenomas, respectively. Nine of 20 lesions showed focal dysplasia pathologically. Among the nine adenomas with dysplasia, two adenomas showed focal cancerous change. The nine adenomas showing focal dysplasia measured 25.6mm (14-35mm) in mean diameter, while the mean diameter of adenomas without dysplasia was 8.7 mm (3-13mm). The echogenicity of adenoma with focal dysplasia were hyperechoic in 8, isoechoic in 1. The echogenicity of adenomas without dysplasia were hyperechoic in 7, isoechoic in 4. Sessile(7/9) and papillary shape(6/9) were predominant in adenoma with dysplasia, but smooth shape(8/11) and stalked type(9/11) were predominant in adenoma without dysplasia. Two adenomas with focal cancerous change showed histological transition from cancer to dysplasia and to adenomatous tissue. In adenoma with dysplasia, the diameter more than 14 mm on sonography was statistically significant (p<0. 005). Also age of patient was significantly different between the two groups (p<0.01), while echogenicity and associated stone were not statistically significant. CONCLUSION: As gallbladder adenoma more than 14ram in diameter on US is suggestive of dysplasia on pathology, so, close follow up US or surgery is recommended.

A 44-year-old man was cutting an outer plate of a ship, at a depth of 25 m below sea level. Following a sudden explosion, he was discovered unconscious and was carried to the surface by other divers. There was no evidence of vital signs upon arrival at the hospital. Postmortem computed tomography, which was performed prior to autopsy, revealed massive pneumocephalus in the brain, pneumohemothorax, diffuse lung contusions with multiple traumatic lung cysts, air-fluid level in the cardiac chamber of the chest, and pneumoperitoneum in the abdomen. Postmortem external examination showed a circular abrasion on the jaw, diffuse subcutaneous emphysema, and contusion in the right upper arm. An internal examination revealed intravascular air bubbles in all four chambers of the heart, and diffuse pulmonary trauma including contusion, laceration, and multiple traumatic cysts. Blast injury to the chest, and air embolism due to the underwater explosion were established as the underlying cause of death.

OBJECTIVE: In order to compare and find the HRQOL and it's determinants among occupationally injured workers, TA patients and general workers, we performed a crosssectional study in Masan and Changwon city, Korea. METHODS: Cases were 169 occupationally injured workers who admitted in the hospital, and controls were 78 TA patients who admitted in the hospital and 166 general workers who worked at Ulsan industrial area. HRQOL were measured by SBQOL. We investigated confounding variables which were age, sex, marital status, employment status, family numbers, monthly income, diagnosis, treatment duration, expectation for health recovery, and expectation for return to work. We compared the HRQOL among occupationally injured workers, TA patients and general workers. We made four factors from twenty three items by factor analysis and used multiple logistic regression to find determinants on HRQOL in each group. RESULTS: There were significant differences in HRQOL between case and control. The main determinants on HRQOL from multiple logistic regression varied in each group. In occupationally injured workers, age(OR 2.73), treatment duration(> 6 months) (OR 3.09) and expectation for return to work(OR 2.62) were main determinants for HRQOL. And age(OR 1.07), marital status(OR 7.41), family members(OR 5.73), expectation for health recovery(OR 4.23) in TA patients. However, monthly income (<1,300,000 won)(OR 1.76) were main determinants for HRQOL in general workers. CONCLUSION: Return to work is major determinants of HRQOL for occupationally injured workers.

Purpose: To report a case of accidental swallowing of nasal packing gauze during silicone tube intubation under local anesthesia.Case summary: A 58-year-old male patient underwent silicone tube intubation for partial nasolacrimal duct obstruction on the right side. In preparing for surgery, six cottonoids soaked were packed in righ nasal cavity, to facilitate anesthesia and prevent bleeding. Strings detectable by X-ray were attached at the cottonoids and cut 5 cm from the nostrils. After surgical hand scrubbing, the strings were not present. One cottonoid was found in the nasal cavity, but five cottonoids could not be detected by endonasal endoscopic exploration. The patient said he swallowed “something like sputum”. He did not notice any discomfort and the surgery was performed as scheduled. Abdominal X-ray performed immediately after surgery showed the presence of the five strings in the stomach. The strings were not seen on X-ray conducted 4 days later. The patient defecated normal stools three times and did not notice any discomfort over the course of 4 days. Conclusions Surgeons need to be aware of the possibility of accidental swallowing of nasal packing gauze during nasolacrimal duct surgery. Use of gauze detectable by X-ray is helpful to determine its location.

Purpose: The purpose of this study was to understand the impact of long- and short-term energy drinks on anxiety-like, depressionlike, and cognitive behavior in adolescent rats. Methods: Adolescent rats (age six weeks) were randomly classified into a control group (CON), a long-term administration group (LT), and a short-term administration group (ST). The LT group was orally administered 1.5 mL/100 g (body weight) of energy drink twice daily for 14 days, the ST group was orally administered for one day, and the control group applied the same amount of normal saline. Later, an open-field test, a forced swim test, novel object recognition test, and an 8-arm radial maze test was conducted to assess the rats’ anxiety, depression, and cognitive function. Results: There were different effects in the long- and short-term groups of energy drink administration. In the LT group, anxiety- and depressive-like behavior increased because of increased movement in the side corner and decrease of immobility time. Also, the time to explore novel objects decreased, and the number of correct responses was reduced, indicating a learning and memory function disorder. However, the ST group was not different from the control group. Conclusion These results indicate that long-term consumption of energy drinks can increase anxiety-like, depression-like behavior, and this can lead to decrease in learning and memory functions. Thus, nurse and health care providers should understand the impact of energy drink consumption in adolescence to provide appropriate practices and education.
