  • A kind of Antihistamines, Azelastine HCl which known as modern H1-blockers, was synthesized by four step process using phthalic anhydride, 4-chlorophenylacetic acid, hydrazine 2HCl. The first step was the reaction of removing carboxyl group and hydroxyl group and the second step was saponification of 3-(4-chlorobenzylidene)phthalide. The third step was the nucleophilic addition reactions of primary amines and the fourth step was addition reaction of N-methyl-1-aza-bicyclo[3,2,0]heptane to 4-(4-chlorobenzyl)-1-(2H)phthalazinone. As a result, product was analyzed by FT-IR and $^1H$-NMR and could be obtained with a yield of 80%.

  • Purpose: To develop therapeutic duplication criteria for the drugs used for respiratory diseases. Method: Therapeutic duplication was defined as "more than 2 drug ingredient-usage in which each has the same therapeutic effect and combination therapy does not confer additional therapeutic benefit". Respiratory system drugs approved in Korea were examined for the study. The WHO's Anatomical Therapeutic Chemical Classification System was used for grouping of the corresponding drug ingredients. The principles and recommendations on combination usage or multiple drug regimens were reviewed by using the clinical practice guidelines, textbooks, product labelings, and clinical articles. Clinical expert group consultation was performed and expert opinions were incorporated into the final criteria. Results: Nine hundred sixty two drug products with Korean Food and Drug Administration classification codes of 141, 149, 222, and 229 were evaluated, of which 87 active ingredients were composed. The drug ingredients were classified into 12 groups (antihistamines, oral nasal decongestants, leukotriene receptor antagonists, inhaled anticholinergics, inhaled corticosteroids, oral ${\beta}2$-agonists, long-acting ${\beta}2$-agonists, short-acting ${\beta}2$-agonists, xanthines, antiallergics, mucolytics and cough suppressants). The use of more than 2 drug ingredients including the same group was therapeutic duplication, and thus combination should be recommended not to be used. Conclusion: Twelve drug groups were identified as therapeutic duplication criteria. Combination therapy within each group should not be used otherwise therapeutic benefits outweigh potential risks.

  • Purpose : This study aimed to analyze the level of understanding of Korean children and adolescents of caries risk assessment items in order to develop caries risk assessment tools. Methods : A total of 52 parents and 108 middle and high school students were analyzed for their understanding of nine items of the CAMBRA CRA for Korean children and adolescents. The nine questions were analyzed through a Likert five-point scale. Centralized distribution analysis was conducted to compare significant differences in the three groups' understanding of the questions. Results : The evaluation of the middle school and high school students' understanding showed that four items scored less than 3.0 points. The items were "Hyposalivatory medications (antihistamines, antipsychotics, asthma, etc.)," "Brushing below once a day," "F varnish last six months," and ".12 % chlorhexidine gluconate mouthrinse daily seven days monthly." The understanding of elementary school parents of ".12 % chlorhexidine gluconate mouthrinse daily seven days monthly" was less than 3.0 points. In addition, as a result of comparing the averages of the three groups, a statistically significant difference (p<.05) was found for a total of five items: "Hyposalivatory medications (antihistamines, antipsychotics, asthma, etc.)," 'Not used oral products such as floss and interdental toothbrushes," "F toothpaste 2× daily or more," "F varnish last six months," ".12 % chlorhexidine gluconate mouthrinse daily seven days monthly." Conclusion : This study was conducted to provide basic data for the development of a caries prevention program by identifying whether the caries risk assessment reconstituted in Korean style can be used for children and adolescents. More than half of the questions scored 3.0 points or higher and were generally completed. Nonetheless, a systematic program can only be completed if a plan is secured to improve repondents' understanding of the questions before a caries prevention program is developed.

  • Cholinergic urticaria with acquired generalized hypohidrosis, and its pathophysiology is not well known. Autoimmunity to sweat glands or to acetylcholine receptors on sweat glands has been mentioned as one of the possible etiologies. Systemic steroid therapy, antihistamines, anticholinergics, and avoidance of the stimulatory situations are recommended for treatment. We experienced a case of cholinergic urticaria with acquired generalized hypohidrosis in a patient who had no other associated disease, and the symptoms eased after repeated bilateral stellate ganglion block. Stellate ganglion block normalized the elevated sympathetic tone and may relieve symptoms in patients with this condition.

  • The effects of various drugs on the alleviation of the symptoms of chemical bums were evaluated in mice to formulate topical antiblister preparations. After a chemical bum was induced on the mouse dorsal skin with 2-chloroethylethyl sulfide, the drug was applied on the disease site. The effectiveness of the drug was evaluated by determining blister size, necrosis score of skin and appearance of the chemical burns induced. It showed that steroids and aminoglycoside antibiotics had a tendency to protect skin cell, and antihistamines decreased the size of chemical bums. While oleaginous base resulted in deleterious effect, hydrophilic base didn't show a significant difference on the alleviation of the chemical burn symptoms compared to the control.

  • The purpose of this study is to promote health for young female workers. It is based on questionnaires collected from 215 female workers in Incheon area. This study includes health condition (fatigue scores), occupational disease, knowledge of abused drugs and the actual condition of drug use. The results are summerized as follows: - $47.4\%$ visited their health center and were treated with diseases like cold and headache $(34.9\%)$, gastroenteric disease $(6.5\%)$, trauma $(7.9\%)$ and chronic disease such as diabetes and hypertension $(3.3\%)$ - $44.7\%$ received regular health education and $4.7\%$ among them received education on abused drugs. - $20.5\%$ were suffering from work related diseases such as gastroenteric disease, headache, trauma, repiratory disease, skin problem, arthritis, low back pain, shortsightness and tuberculosis. - Total mean fatigue score as an indication of health status was $9.0\pm5.4$ points out of 30 points. Physical mean score (group I) was $3.92\pm2.2$ points and psychological mean score was $2.5\pm2.3$ points and neurosensory mean score was $2.6\pm2.1$ points out of each 10 points. - They recognized analgesics $(55.0\%)$ and the next are laxatives $(49.8\%)$, inhalants $(40.0\%)$, narcotics $(24.2\%)$, stimulants $(24.0\%)$, antihistamines$(5.9\%)$, diuretics $(3.0\%)$, tranquilizer $(2.4\%)$ and sedatives $(1.4\%)$ - They used analgesics $(37.2\%)$ the most and then laxatives $(6.0\%)$, stimulants$(5.6\%)$, diuretics $(1.9\%)$, antihistamines$(0.5\%)$, And nobody used tranquilizer, sedatives, narcotics and inhalant. - The relationship between career, drug abuse education, health center utilization and and the actual condition of drug using was examined. The longer the career and the more educated with drug abuse, the less drug used. And those who utilized health center rarely used more drugs. - The relationship between career, health center utilization, the score of fatigue and use of analgesics was also examined. Those group who have a longer career above 3 years and the group who have never used health center used more analgesics. And the group of fatigue score above 11.0 points used a little more analgesics than the other group. These results indicate that analgesics are the most frequent used drugs among female workers. Those analgesics such as geborin, penzal, saridon, aspirin, tyrenol should be used properly. These basic data is submitted for the education and consultation which are carried out by industrial nurses for promoting health of industrial workers.

  • Sensorineural hearing loss(SNHL) is defined as a sudden hearing impairment which was develope over a period of hours to days. The definitive cause of SNHL is unknown in most cases. Disturbance of the blood flow of the inner ear is a main causal hypotheses. Most symptomatic treatment is focusing to improving the blood flow of the inner ear. At our hospital, most patients are recommended to bed rest, vasodilators(nicotinic acid, antihistamines) and stellate ganglion block(SGB) for two weeks. We experienced two cases of recurrence immediately after recovery from SNHL. They discontinued SGB after initial recovery. due to associated pain with operation and or psychologic stress. One patient resumed SGB and medication treatment, but the second who gave up treatment was not recovered. Therefore, we recommend to continuance of treatment of stellate ganglion blocks to improve recovery rate of SNHL and avoid further trauma and psychologic stress during the recovery period of SNHL.

  • Purpose: This study aims to analyze the current state of emergency care for patients with anaphylaxis and to identify problems and areas for improvement in prehospital care. Methods: This study was conducted using 119 emergency running sheets and medical records of 109 patients diagnosed with anaphylaxis. Questionnaires were also given to emergency medical technicians (EMTs) and emergency physicians. The data were analyzed using SPSS 21.0. Results: Prehospital emergency care included oxygen administration in 64.2%, an intravenous line in 15.6%, and medication injection in 11.0%. The most commonly administered medications were antihistamines in 66.7% and epinephrine in 8.3%. Of EMTs surveyed, 47.0% suggested an epinephrine injection and using direct medical control, while 53.8% of the emergency physicians suggested an epinephrine injection and using indirect medical control. Most emergency physicians 88.8% responded that epinephrine could be administered by EMTs. Conclusion: The data support epinephrine injection of patients with anaphylaxis by EMTs, but a larger sample size of EMTs is required. Education about the treatment of anaphylaxis should be improved for EMTs. The scope of paramedic responsibilities should also be redefined.
