  • Background: Ma-huang (Ephedra sinica) has been widely used to treat respiratory disease in oriental medicine for over a hundred years. Ma-huang preparations contain approximately 1.25% ephedrine alkaloids. Recently, the ephedra alkaloids have received much press lately due to adverse effects in those using whole extracts as 'dietary supplements' for weight loss or athletic performance enhancement, and these reports are troubling given the increasing use of Ma-huang by the general public. The purpose of this report is to determine the proper dosage to minimize adverse effects and maximize the potential curative value. Objectives : The object of this study was to find an effective yet low risk dosage of Ma-huang. Methods : The study was designed as a double-blind randomized placebo-controlled trial. The subjects of this study were 26 adults between 20 to 40 of age who agreed to participate in this study. They were allocated through randomization into three groups. Each group took three opaque capsules three times a day. A group (N=9) took one Ma-huang capsule and two placebo capsules, B group (N=8) took two Ma-huang capsules and one placebo capsule, C group (N=9) took three Ma-huang capsules. The total trial periods was two days. To compare the adverse effects of Ma-huang according to dosage, blood pressure and pulse were checked, and other adverse effects were assessed using a morning questionnaire, patient's global assessment scale and Wong-Baker faces pain rating. Results : The following result were obtained: 1. After taking 18 g of Ma-huang per day, pulse rate had a significant increase. 2. After taking more than 6 g of Ma-huang per day, palpitation would be increased significantly. 3. After taking more than 18 g of Ma-huang per day, tiredness would be increased significantly. Conclusion: According to the results, 12 g of Ma-huang per day will minimize adverse effects and maximize the potential curative value.

  • The objective of this study is to review retrospective exposure assessment methods used in wafer fabrication operations to determine whether adverse health effects including mortality or cancer incidence are related to employment in particular work activities and to recommend an appropriate approach for retrospective exposure assessment methods for epidemiological study. The goal of retrospective exposure assessment for such studies is to assign each study subject to a workgroup in such a way that differences in exposure within the workgroups are minimized, as well as to maximize the contrasts in exposure between workgroups. To reduce the misclassification of exposure and to determine if adverse health effects including mortality or cancer incidence are related to particular work activities of wafer fabrication workers, a minimum requirement of work history information on the wafer manufacturing eras, job and department at which they were exposed should be assessed. Retrospective assessment of the task that semiconductor workers performed should be conducted to determine not only the effect of a particular job on the development of adverse health effects including mortality or cancer incidence, but also to adjust for the healthy worker effect. In order to identify specific hazardous agents that may cause adverse health effects, past exposure to a specific agent or agent matrices should also be assessed.

  • Toad venom, 'Chan su' in Chinese and 'somso' in Korean, is a well-known traditional oriental medicine obtained from the skin venom gland of the toad. Formulations of toad venom have been widely applied in China, Japan, Korea and other oriental countries for a long time. It is often found in traditional Chinese formulations, such as Jiuxin (or Kyushin in Japan), Yixin, Huoxin, Shexiang baoxin wan, Lu shen wan and Laryngitis pills. According to a pharmaceutical chemistry study, toad venom contains multiple biological active substances, such as bufalin, resibufogenin and cinobufagin. Modern pharmacological studies indicated that toad venom has multiple pharmacological actions, including acting as a cardiotonic, antitumor local anesthetic effects, stimulates the respiratory center, vasopressor action, anti-inflammatory and diuretic effects. Like other medications, toad venom also has certain toxicity and adverse effects, for example, inducing delayed afterdepolarization and triggered arrhythmia. The major chemical constituents, basic pharmacological actions and adverse reactions of toad venom are discussed in this article.

  • Purpose: This study was to explore the perception about menstruation and discomforts of using disposable menstrual pads in menstruating women. Method: A survey was conducted of 132 menstrual women recruited by convenience sampling. Data were collected by a face-to-face interview and a study questionnaire, and analyzed by frequency and $X^2$-test. Result: More than half of the subjects expressed a negative perception about menstruation, while 25% expressed a mixed perception and 24.2% expressed a positive perception. Women who perceived their menstruation negatively had more menstrual pain than the others (p<.001). The most frequently experienced discomforts of using disposable pads were an unpleasant smell (18.9%), leakage (18.9%), and discomfort (16.6%). Adverse effects of using disposable pads were reported as an itching sense (23.1%). skin rash (20.2%), and skin irritation (10.6%). Alternate materials were reported with tampons, alternate washable pads, and maternity pads. Conclusion: The results indicate that disposable menstrual pads cause several discomforts and common adverse effects such as skin problems. To decrease these discomforts and relieve adverse effects, planned nursing education including women's personal hygiene methods and information about an alternate pad may be helpful.

  • Sexual dysfunction is a relatively common adverse effect in the use of antidepressants. The sexual side effects may result in a lack of compliance with the prescribed antidepressants. The author reviewed the prevalence and updated treatment for the antidepressant-induced adverse effects focusing on sexual dysfunction. The incidence of sexual dysfunction is reported to exceed more than 50% especially with SSRIs. In order to obtain a quantified baseline and as an ongoing evaluation tool, clinicians may use some of the established questionnaires and validated instruments such as the Arizona Sexual Experience scale and Changes in Sexual Functioning Questionnaire. Clinicians should be aware that delayed ejaculation and orgasm, symptoms most frequently associated with antidepressants, are not usually associated with depression itself. Although many antidotes have been proposed, few have been subjected to double-blind trials. Some evidences have suggested that bupropion and buspiron may be the effective antidotes for SSRI induced sexual dysfunction. Additional trials will be requied to define what role, if any, bupropion and buspiron might have in the treatment of SSRI-induced sexual side effects. The available evidence is rather limited, with only small number of trials assessing each strategy. While further randomized data is awaited, for men with antidepressant induced erectile dysfunction, the addition of sidenafil or tadalafil may appear to be an effective strategy.

  • Lidocaine, a local anesthetic commonly used in dental treatments, is capable of causing allergies or adverse effects similar to allergic reactions. However, the frequency of such occurrences in actual clinical settings is very rare, and even clinical tests on patients with known allergies to local anesthetics may often show negative results. When adverse effects, such as allergy to lidocaine, are involved, patients can be treated by testing other local anesthetics and choosing a local anesthetic without any adverse effects, or by performing dental treatment under general anesthesia in cases in which no local anesthetic without adverse effects is available. Along with a literature review, the authors of the present study report on two cases of patients who tested positive on allergy skin tests for lidocaine and bupivacaine and subsequently underwent successful dental treatments with either general anesthesia or a different local anesthetic.

  • Objectives : The aim of this review is to investigate studies on skin adverse reactions and to demonstrate subjects related to the adverse effects in dermatology. Methods : Electric searches were performed with KISS(Korean studies Information Search System) and the key words were combination of 'skin' and 'adverse effect'. 87 literatures investigated in this review were issued from 1900 to 2016. Results : Among the 87 papers, dermatologic adverse reactions were reported in 83 papers in medicine, accounting for 95.4%. Of the adverse effects seen on the skin, 84 discoloration such as erythema, pigmentation and hemotelangiosis were the most common, accounting for 21%. Among the medical adverse reactions not seen on the skin, 21 infection were the most common, accounting for 25%. Among the subjective adverse reactions, of which 32 pruritus were the most common, accounting for 43%. Among the 87 papers, there were 3 cases with underlying diabetes and 3 cases with underlying hypertension, followed by 2 cases with chronic renal failure, HBV, atopic dermatitis and respectively 1 case with alcoholism, depression addiction, multiple myeloma, arthritis and psoriasis. The most frequent period until adverse reactions appeared was within 2 weeks, accounting for 13 papers. And 4 were the most frequent adverse reactions lasting less than 1 month, and 4 were more than 3 months and less than 6 months. There were 48 cases where adverse reactions were caused by nonmedical practioner's treatment. The adverse reactions by the pharmacist were the highest at 11 cases (23%). There were 17 cases of adverse reactions due to medical treatment, among which dermatologists and nondermatologists accounted for the majority of 5 cases, 29%. The most common cause of adverse reactions was the application of external medicine (41 cases), followed by 36 cases of foreign body implantation, eyebrow tattooing, ear piercing, etc. Conclusions : In this report, we demonstrated patterns of adverse reactions in the medical field of dermatology caused by non-medical personnel than medical personnel. We suggest that more effort should be followed by medical personnel to establish clear awareness of skin disease and by patients to be aware of the risks of the illegal medical treatment by non-medical personnel.

  • The ubiquitous computing & technology is to make passive IT machinery as the smart-object to solve the problems of information management. These ubiquitous devices can be a concierge of humans lives. In addition, the ubiquitous computing & technology added with Pro-Active processing technology is the intellectual automatic process capacity that probably enhance quality of human's life. Although the social influencing power of ubiquitous computing technology is so critical, research on the social impact of ubiquitous has been studied insufficiently. And, we also need the countermeasures to protect the societies from the side effect of the ubiquitous computing technology. The purpose of this research is to minimize the loss which comes from the new ubiquitous society, by presenting the technological and systematic alternatives and by researching the various side effects. This research suggests the proper alternatives by reviewing and by researching the adverse effects of the ubiquitous computing technology.

  • Background: The adverse effects of the phosphodiesterase-4 inhibitor roflumilast, appear to be more frequent in clinical practice than what was observed in chronic obstructive pulmonary disease (COPD) clinical trials. Thus, we designed this study to determine whether adverse effects could be reduced by starting roflumilast at half the dose, and then increasing a few weeks later to $500{\mu}g$ daily. Methods: We retrospectively investigated 85 patients with COPD who had taken either $500{\mu}g$ roflumilast, or a starting dose of $250{\mu}g$ and then increased to $500{\mu}g$. We analyzed all adverse events and assessed differences between patients who continued taking the drug after dose escalation and those who had stopped. Results: Adverse events were reported by 22 of the 85 patients (25.9%). The most common adverse event was diarrhea (10.6%). Of the 52 patients who had increased from a starting dose of $250{\mu}g$ roflumilast to $500{\mu}g$, 43 (82.7%) successfully maintained the $500{\mu}g$ roflumilast dose. No difference in factors likely to affect the risk of adverse effects, was detected between the dose-escalated and the discontinued groups. Of the 26 patients who started with the $500{\mu}g$ roflumilast regimen, seven (26.9%) discontinued because of adverse effects. There was no statistically significant difference in discontinuation rate between the dose-escalated and the control groups (p=0.22). Conclusion: Escalating the roflumilast dose may reduce treatment-related adverse effects and improve tolerance to the full dose. This study suggests that the dose-escalated regimen reduced the rate of discontinuation. However, longer-term and larger-scale studies are needed to support the full benefit of a dose escalation strategy.
