We report a case of acantholytic dyskeratotic epidermal nevus in a 28-year-old female. The patient showed unilateral, asymptomatic, grouped, 2 mm sized, brownish, follicular ant non-follicular, keratotic papules disposed along Blaschko´s lines on the right side of th back, flank and abdomen. She had had this condition for 4 years. The biopsy specimen obtaine, from the abdomen showed hyperkeratosis, parakeratosis, acanthosis, acantholytic suprabasal clefts, corps ronds, and grains. Although cryotherapy with liquid nitrogen was per formed on half of the lesions, the whole skin lesions healed with focal hypertrophic scars 4 weeks later. There was no recurrence after a 12 months follow-up period. To our knowledge this is the first reported case of acantholytic dyskeratotic epidermal nevus in Korean dermatologi, literature.

BACKGROUND: Direct observation of healthcare workers is commonly used in hospitals to investigate hand hygiene compliance. However, the hand hygiene compliance rate may increase due to the Hawthorne effect, which is the modification of behavior simply because subjects become aware that they are being observed. The objective of this study was to investigate the occurrence of the Hawthorne effect when directly observing hand hygiene compliance in intensive care unit (ICU) healthcare personnel. METHODS: A total of 87 staff members from the coronary care unit and cardiac surgery ICU of a general hospital in Seoul were included in this study: 24 residents and interns, 55 nurses, and 8 nursing assistants. Both covert and overt observations, where subjects were either unaware or aware of any direct observation, were performed on separate occasions. RESULTS: A total of 1,052 covert and 1,336 overt observations were documented over 30 and 34 occasions, respectively. Overall hand hygiene compliance was significantly higher with overt observation than with covert observation (1,041/1,336, 77.9% vs. 659/1,052, 62.6%, P<0.001). The Hawthorne effect was present in all professions and behaviors, with the exception of nursing assistants, and prior to touching a patient. CONCLUSION: Direct observation of hand hygiene compliance was associated with the Hawthorne effect when observations were made overtly and this was likely to contribute to an overestimation of compliance rate.

Urine discoloration occurs in the intensive care unit (ICU) due to many causes such as medications, metabolic disorders, and infections. Propofol is advocated as one of the first line sedatives in the ICU, but it is not well known to the intensivists that propofol can induce urine color change. We experienced two cases of green urine after propofol infusion. Propofol should be warranted as the cause of urine discoloration during ICU stay.

BACKGROUND: Glutaraldehyde is used most commonly as a high-level disinfectant for semicritical patient-care equipments. However, its potential toxicity to healthcare workers and a long exposure time needed to kill mycobacteria can be problematic. Recently, Perasafe(R) (Antec International, UK) has been introduced in the market as a safe and very effective disinfectant. This study was to evaluate the efficacy of Perasafe(R) against not only bacteria and yeast but also mycobacteria and bacterial spores and compare it with glutaraldehyde. MATERIAL AND METHOD: Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans, Mycobacterium tuberculosis, and Bacillus subtilis were used for the test. Perasafe(R) and Cidex(R) were used at the final concentration of 1.62% and 2.25%, respectively; the disinfectants were neutralized by Tween 80 (0.5%) in the mycobacterial test and by lecithin (0.75%) in all other tests. Bacterial suspensions were made in phosphate buffer with or without fetal bovine serum (1%) to simulate dirty or clean conditions, respectively. The disinfectants were tested at 0, 24 and 48 hr of preparation to check stability. An effective disinfectant activity was defined as a 5 log10 reduction in viable counts. RESULTS: E. coli, S. aureus, P. aeruginosa and C albicans were effectively disinfected in less than 5 min by both Perasafe(R) and Cidex(R) and the both disinfectants remained equally effective under the dirty conditions or at 48 hr of preparation. Perasafe(R) was effective in 1 min against B. subtilis spores compared to Cidex(R) which took 30 min for the same activity. M. tuberculosis was effectively disinfected in 10 min by Perasafe(R) and 20 min by Cidex(R). CONCLUSIONS: Perasafe(R) showed greater tuberculocidal and sporicidal activities than Cidex(R), although both disinfectants were equally effective against common bacterial and yeast pathogens. Perasafe(R) may be an outstanding high-level disinfectant for endoscopes and other semicritical medical equipment.

Objectives: This study aimed to examine the effect of eating habits and dietary attitudes on dessert consumption among university students in Gwangju Province, South Korea. Methods: A survey was conducted from May to June 2022. Out of 300 distributed questionnaires, 261 valid responses were included in the analysis. The survey assessed dessert selection, satisfaction, consumer attitudes and behaviors, as well as factors influencing satisfaction. Results: Both genders reported purchasing desserts 2 to 3 times per week, primarily after lunch, due to the convenience of dessert accessibility. Males favored ice cream, bakery items, and fruits, while females preferred bakery items, ice cream, and fruits in that sequence. ‘Having fun’ was identified as the most common motivation for dessert consumption post-meal. Notable gender disparities emerged regarding perceptions of dessert consumption, including its role in stress relief, potential for nutritional imbalance, positive effects, and preferences for seasonal menus. Significant gender-based differences also manifested in intentions to purchase dessert, responsiveness to price changes, and inclination to recommend desserts to others. Conclusions This study offers foundational data on university students’ dessert purchasing behaviors, perceptions, and satisfaction levels, intending to inform strategies promoting healthier dietary habits.

Pilomatrix carcinoma is a rare malignant neoplasm. It can develop de novo or by a malignant transformation from an existing pilomatricoma. Clinically, it presents as an asymptomatic, variable sized, firm, deep seated nodule on the posterior neck and upper back of middle-aged men. Histologically, it has features of pilomatricoma as well as nuclear atypia and more numerous mitoses. It is a locally aggressive tumor that has a tendency to recur. We report a case of pilomatrix carcinoma in 46-year-old woman who presented a 1.5 X 1cm sized, hard and movable nodule on her neck for 1 month.

Radioactive iodine (RAI) therapy is widely used for the treatment of Graves disease. After RAI therapy, 44% become hypothyroid and up to 28% remain hyperthyroid. The development of thyrotoxicosis after RAI therapy is believed to be mediated by 2 different mechanisms: a transient increased release of thyroid hormone due to radiation thyroiditis and the rare development of Graves disease due to the formation of antibodies to the thyroid-associated antigens released from the damaged follicular cells. A 55-year-old woman was hospitalized with severe headache, weight loss, and palpitation. She received a dose of 7 mCi of RAI (I-131) about 6 weeks earlier. Thyroid function test showed 7.98 ng/dL free T4, >8 ng/mL T3, <0.08 microIU/L thyroid stimulating hormone, and high titer thyroid stimulating immunoglobulin (TSI) (85.8 IU/L). She improved with propylthiouracil, propranolol, and steroid treatment. The TSI, however, was persistently elevated for 11 months.

Background: Dispensing of prescription drugs is the most important task for community pharmacists. However, the public’s satisfaction with pharmacist services is not high, and distrust due to dispensing by unqualified person and/or under unsanitary conditions led to demands for transparent dispensing room (TDR) in pharmacies. Objective: This study was conducted to investigate how pharmacy students perceive pharmacists’ credibility and professional ethics in conjunction with the TDR issue. Methods: A survey using 20-items questionnaire was conducted from July 12 to 20, 2019 in pharmacy students nationwide. Results: Among 218 respondents, 84.1% attended pharmacy school located in the metropolitan area, 61.1% were the 3rd or 4th graders, and 81.2% had no practical training in community pharmacy. 56.2% were unaware of the TDR issue, and 66.8% agreed on the public’s demand for TDR. 68.8% disagreed that TDR was the best way to solve the problem of unqualified dispensing, while 51.9% agreed that TDR was the best way in solving unsanitary dispensing problem. Publics’ confidence level of community pharmacists was mean 5.84 (range 1-10). In a question asking how expertise and professional ethics affect pharmacist confidence, 50% said expertise was more important, 31.7% the same, and 18.3% said professional ethics was more important. Conclusions To overcome the demand for TDR which began with public distrust in pharmacists, it is necessary to seek measures to increase the credibility of pharmacists, and as part of this, pharmacist ethics should be systematically educated at pharmacy school.

PURPOSE: Addressing a patient's chief complaint is the first and key element of treating patients. This study determined the effectiveness of emergency medical technician and residents of an emergency department in addressing a patient's chief complaints. If emergency and hospital personnel misunderstand the chief symptoms of patients it could result in erroneous transport and treatment, thus losing precious time in finding the proper treatment. METHODS: A retrospective chart review study was performed in 1137 patients (at least 18 years of age), who visited one university hospital, for a period of 3 months. Patients who were did not undergo trauma, addiction, and cardiac arrest were included. RESULTS: A total of 150 cases (13.2%) did not match the chief symptoms reported by 119 emergency medical personnel and emergency medicine residents. Systemic symptoms, nervous system symptoms, and psychiatric symptoms were the main categories inconsistently assessed. The rank and certification of emergency medical technicians did not make a difference, but older patients (59 years of age or older) were statistically different. The assessment fo chief symptoms by an emergency medical resident tended to be more accurate than assessment of emergency medical technicians in the final diagnosis. CONCLUSION: Systemic symptoms, nervous symptoms, and psychiatric symptoms, were chief complaines easily misreported for older patients. This likely reflects a difficulty in the evaluation of obscure symptoms in older patients. It will require specific additional training programs to improve the response to these chief complaints.
