  • The side effects of using drugs can greatly threaten the health of the public. The reality is that there are very few reports of current side effects. This can be activated by linking adverse drug reactions reporting to the Drug Utilization Review (DUR) currently used by pharmacies. A study of the U.S. medication management system, where drug use assessment is activated, can find ways to activate adverse drug reactions reporting. In 'Pharm IT 3000', which is used as a medication management program in pharmacies, we examined how to enable reporting of adverse drug reactions. The literature study and research on actual program operation have found a convenient way to report side effects by linking the Pharm IT 3000 prescription preparation assessment to the item.

  • For continuous operation of the sulfur-iodine(SI) thermochemical cycle, which is expected practical method for massive hydrogen production, suggesting operation conditions at steady state is very important. Especially, in the Bunsen reaction section, the Bunsen reaction as well as side reactions is occurring simultaneously. Therefore, we studied on the relation between the variation of compositions in product solution and side reactions. The experiments for Bunsen reaction were carried out in the temperature range, from 268 to 353 K, and in the $I_2/H_2O$ molar ratio of $0.094{\sim}0.297$ under a continuous flow of $SO_2$ gas. As the result, sulfur formed predominantly with increasing temperature and decreasing $I_2/H_2O$ molar ratios. The molar ratios of $H_2O/H_2SO_4$ and $HI/H_2SO_4$ in global system were decreased as the more side reaction occurred. A side reactions did not appear at $I_2/H_2O$ molar ratios, saturated with $I_2$, irrespective of the temperature change. We concluded that it caused by the increasing stability of an $I_{2x}H^+$ complex and a steric hindrance with increasing $I_2/HI$ molar ratios.

  • Conservative therapy with appropriate antibiotics is essential for most patients with infectious spondylitis. Although most antibiotics do not cause problems if it used properly and serious side effects are rare, side effects can occur with any class of drugs and adverse reactions of antibiotics can range from mild allergic reactions to serious and fulminant adverse events. These side effects are also extremely variable from patient to patient and from antibiotic to antibiotic. A side effect of antibiotics may paradoxically increase inflammatory marker levels. Here, the author presents two cases of antibiotic-induced increase in inflammatory markers in cured infectious spondylitis. The patients were successfully treated after stopping the antibiotic therapy. The differential diagnosis between antibiotic side effects and infection should be considered very carefully because the treatment is completely different. Although the exact mechanisms underlying successful treatment without antibiotics are unclear, we should consider the side effects of antibiotics when following inflammatory markers during treatment of infectious spondylitis.

  • Hyaluronidase, an enzyme that breaks down hyaluronic acid, has long been used to increase the absorption of drugs into tissue and to reduce tissue damage in cases of extravasation of a drug. With the increasing popularity of hyaluronic acid filler, hyaluronidase has become an essential drug for the correction of complications and unsatisfactory results after filler injection. For this reason, when performing procedures using hyaluronic acid filler, a sufficient knowledge of hyaluronidase is required. In order for hyaluronidase to dissolve a hyaluronic acid filler, it must interact with its binding sites within the hyaluronic acid. The reaction of a filler to hyaluronidase depends on the hyaluronic acid concentration, the number of crosslinks, and the form of the filler. Hyaluronidase is rapidly degraded and deactivated in the body. Therefore, in order to dissolve a hyaluronic acid filler, a sufficient amount of hyaluronidase must be injected close to the filler. If the filler is placed subcutaneously, injection of hyaluronidase into the filler itself may help, but if the filler is placed within a blood vessel, it is sufficient to inject hyaluronidase in the vicinity of the vessel, instead of into the filler itself. Allergic reactions are a common side effect of hyaluronidase. Most allergic reactions to hyaluronidase are local, but systemic reactions may occur in infrequent cases. Since most allergic responses to hyaluronidase are immediate hypersensitivity reactions, skin tests are recommended before use. However, some patients experience delayed allergic reactions, which skin tests may not predict.

  • In the reaction furnace of modified Claus process, chemical equilibrium reactions and kinetic reactions occur simultaneously. The main kinetic components are hydrogen ($H_2$), carbon monoxide (CO), carbonyl sulphide (COS) and carbon disulphide ($CS_2$). The equilibrium calculations, empirical correlations and sulfur recovery technology providers' (licensors) data for kinetic components (COS and $CS_2$) in the reaction furnace were analyzed to evaluate the amount of kinetic components by applying them to five different projects in which GS Engineering & Construction participated. Kinetic components ($H_2$ and CO) are also calculated and the results are analyzed to evaluate the impact of temperature in the reaction furnace and the waste heat boiler. Total required $O_2$ deviations for combustion in the reaction furnace are additionally shown, with and without side reactions. A full understanding of side reactions in the modified Claus process can help to improve sulfur recovery efficiency and optimize equipment design.

  • Li2O-based cathodes utilizing oxide-peroxide conversion are innovative next-generation cathodes that have the potential to surpass the capacity of current commercial cathodes. However, these cathodes are exposed to severe cathode-electrolyte side reactions owing to the formation of highly reactive superoxides (Ox-, 1 ≤ x < 2) from O2- ions in the Li2O structure during charging. Succinonitrile (SN) has been used as a stabilizer at the cathode/electrolyte interface to mitigate cathode-electrolyte side reactions. SN forms a protective layer through decomposition during cycling, potentially reducing unwanted side reactions at the interface. In this study, a composite of Li2O and Ni-embedded reduced graphene oxide (LNGO) was used as the Li2O-based cathode. The addition of SN effectively thinned the interfacial layer formed during cycling. The presence of a N-derived layer resulting from the decomposition of SN was observed after cycling, potentially suppressing the formation of undesirable reaction products and the growth of the interfacial layer. The cell with the SN additive exhibited an enhanced electrochemical performance, including increased usable capacity and improved cyclic performance. The results confirm that incorporating the SN additive effectively stabilizes the cathode-electrolyte interface in Li2O-based cathodes.

  • Purpose: This study was conducted to identify factors affecting COVID-19 vaccination and associated side effects among health care workers in a small and medium-sized hospital. Methods: In May 2021, 301 workers out of a total of 670 working in a small and medium-sized hospital in Gyeonggi-do, were surveyed. The small and medium-sized hospital treats patients with COVID-19. Health care workers across different medical institutions responded with self-reported internet questionnaires. Factors influencing COVID-19 vaccination were analyzed via logistic regression. Results: Out of 301 subjects, 89.0% showed an intention to inoculate, and 85.7% were vaccinated against COVID-19. The most frequent reason for vaccination was responsibility as a medical worker. The fear of adverse reactions was the most frequent reason for non-vaccination. Adverse reactions after inoculation occurred in 70.9% of cases, and 30.6% were referred for treatment of adverse reactions. The factors ultimately influencing COVID-19 vaccination were vaccination intention, previous side effects from other vaccinations, occupation, and age. Conclusion: In order to improve the effectiveness of COVID-19 vaccination, a systematic approach is required to determine the risk factors associated with the young age of the administrative staff/personnel, subjects with a history of side effects associated with other vaccines, and health care workers who do not intend to be vaccinated. It is important to develop strategies to improve immunization. In addition, accurate and essential information regarding the side effects of vaccination is needed, along with appropriate education and publicity.

  • The objectives of this study were to survey the adverse reactions by Taeeumjowi-tang and to compare the tendency of symptoms by Sasang constitutional type. The clinical data for this study were based on the medical records of 78 cases collected from an oriental clinic. The major results of this survey are following: The 5.8% of Taeeum-in who took Taeeumjowi-tang showed side effects. And the 52.4% of Soeum-in and 41.6% of Soyang-in also showed side effects against Taeeumjowi-tang. They complained of excitation, irritability, restlessness, hypersensitivity, tinnitus, insomnia, upper abdominal discomfort, poor appetite, thirst, perspiration, dizziness, chest pain, tremor and evacuation troubles in common. And these adverse symptoms were similar to that by Ma-hwang. Therefore if we make a suitable medication guide for Ma-hwang based on Sasang constitutional type, it will be able to maximize the efficacy and minimize the adverse effect.
