The nevus of Ota is a benign dermal melanocytic lesion that most commonly occurs unilaterally in areas innervated by the first and second division of the trigeminal nerve. Acquired bilateral nevus of Ota-like macules(ABNOM) are located bilaterally on the forehead, temples, eyelids, cheeks, and/or nose. They usually occur in the fourth or fifth decade of life in women(rarely in men). In contrast to the nevus of Ota, ABNOM have not been observed in the mucous membranes of the oral cavity, nose, or eyes. Traditional treatments were palliative, risky electrocautery, or cryotherapy. These methods resulted in permanent pigmentary changes and/or scarring. Recently utilizing the principle of selective photothermolysis, the Q-switched Alexandrite laser has been reported to be successful in treating benign pigmentary lesions and tattoos. Our study evaluated the treatment of 127 patients with nevus of Ota and ABNOM with the Q-switched Alexandrite laser(755 nm, 100 nsec). Nevi were treated up to 7 times with 7-8 J/cm2 at a minimum of 6 weeks interval. Good therapeutic effects were gained (up to 50% improvement was seen in 89% of patients.) and our patients were very satisfied. No patients had permanent textural change or scarring. Treatment with on Alexandrite laser for nevus of Ota & ABNOM is considered to be a safe and effective method.

A various type of hairline and height of forehead is considered as a result of genetic effect. The conventional corrective surgical operation of low hairline in forehead has been too complicated and painful to apply, and also has many disadvantages such as scar, bleeding, risks of anesthesia. Recently four classes of devices are designed to remove hair with intense light beam : Nd-Yag lasers with carbon cream, the Ruby lasers, the Alexandrite lasers, and the polychromic broad band light source of flashlamp technology. The goal of these therapeutic modality is to destroy the melanin pigment selectively in hair follicle without injuring the skin for permanent epilation. We have been used long pulse infrared Alexandrite laser for treat low hair line in 27 patients from Dec. 1997 to Dec. 1998. We experienced 3 cases of temporary hyperpigmentation and 1 case of bulla, and the most of patients were satisfied in 89%. The average lengthening of forehead was 2.2cm (median line) and 2.3cm (paramedian line). We achieved successful result without permanent hyperpigmentation or scarring

Open heart surgery with hypothermia in patients with cold agglutinin can cause severe complications by hemolysis and hemagglutination of red blood cells. A 41 year-old male patient with mitral stenosis was admitted due to fever and cough. After antibiotics treatment, he was scheduled to undergo mitral valve replacement. In the operation room, we found agglutination of blood cardioplegia during lowering temperature of cardioplegia. And then, the cardioplegia was changed to warm cardioplegia and the operation was performed under normothermia due to the suspicion of the cold reactive protein. The operation was performed uneventfully. Postoperatively, cold agglutinin was confirmed by immunochemistry of the patient's serum.

OBJECTIVES: Obstructive sleep apnea (OSA) syndrome is diagnosed through history, physical examination, imaging studies and polysomnography. Clinical examination of this condition may point to hypertrophic tonsils and crowded oropharynx. The objective of this study is to investigate the usefulness of modified Mallampati grade (MMG) and tonsil grade (TG) in predicting the severity of obstructive sleep apnea. METHODS: MMG and TG were divided into 4 and 5 groups, respectively, according to their severity. Medical records were collected from 94 patients who had received polysomnography and otorhinolaryngologic examination for snoring and sleep apnea at Keimyung University Dongsan Medical Center from March 2002 through April 2004. Patients were divided into two groups according to the apnea-hypopnea index (AHI) : control (n=24), and patients with sleep apnea (n=70). RESULTS: Patients with higher MMG and TG had higher AHI, and MMG and TG proved to have a statistically significant correlation with AHI (p< 0.05) CONCLUSION: MMG and TG were reliable predictors of OSA and helpful parameters in deciding treatment method.

Among the side effects of simvastatin, elevated liver enzyme or creatine kinase activity has been occasionally report-ed, but overt myopathy is rare. We report two cases of simvastatin-induced myopathy with usual dosages of simvas-tatin. Two patients presented with general myalgia, markedly elevated creatine kinase activity, and mild proximal weak-ness. One patient had been treated with concomitant use of cyclosporine and simvastatin after renal transplantation, and another patient had diabetic nephropathy. We recommend careful monitoring when myalgia appears in a patient receiv-ing simvastatin. (J Korean Neurol Assoc 19(4):435~437, 2001)

BACKGROUND/OBJECTIVES:
Despite the rapid growth of the online food delivery service market since the outbreak of coronavirus disease 2019, little research has focused on how consumers are using food delivery service and what they are concerned about when using food delivery service. Moreover, previous studies have not paid adequate attention to how these concerns are related to consumers’ intention to use food delivery service. Therefore, our study examines behaviors and concerns regarding food delivery service and identifies the key factors in consumers’ intention to use food delivery service.
SUBJECTS/METHODS:
Using data collected from 549 Korean consumers, we conducted descriptive analysis, exploratory factor analysis, and multiple regressions.
RESULTS:
We found that using food delivery service is not only for main meals at home or the office but also to meet a variety of dietary needs and occasions. The findings indicated that Korean consumers are most concerned about the sustainability of food delivery service, followed by health, hygiene, hedonic, and usability aspects of the service. Hygiene concerns and a hedonic aspect of the service were negatively associated with consumers’ intention to use food delivery service among users, while health concerns decreased the intention of non-users.
CONCLUSION
The findings have implications for practitioners and policy makers in food delivery service. To further propel market growth, they should help reduce health concerns of non-users, as well as hygiene and hedonic concerns of existing users.
