The development of transport is being easily shared with people all over the world. It is necessary to appropriately and effectively revise the domestic quarantine law because the fatal infectious diseases are at risk of being easily shared. Today, Korea has an advanced quarantine system approved by World Health Organization, but it maintains partnerships with related ministries (Ministry of Foreign Affairs, Ministry of Justice, local medical institutions) and to introduce new medical technology (electronic quarantine) is important. And since the prevention of quarantine infectious diseases and prevention of the spread, in order to maintain international cooperation with the International Health Regulations, the quarantine law and the system should be amended and improved effectively and it is also a way to prepare for the outbreak of new quarantine infectious diseases. In the past, Korea has experienced great confusion during the past outbreak of swine flu and Middle East respiratory syndrome coronavirus. To prevent similar cases from recurring in the past, the revision of the quarantine law and the improvement of the system should be done to cope with the changing environment (new infections, increased number of overseas travelers, etc.).

Recently, hospital acquired infections have an increase interest as a public problems, which are caused of indoor pollutants in hospital. Microorganisms, ethylene oxide, formaldehyde, and anesthetic gases are main hazardous pollutants in hospital. The possible pathways of the infection are a respiratory channel as well as a blood channel. The blood channel is concerned since these pollutants might be dissolved into the Ringer's solution. The objective of this research was to evaluate the removal efficiencies of adsorption trap for formaldehyde and microorganisms as indoor pollutants which permeated into the Ringer's solution. Dissolved formaldehyde in the solution was increased with the injection dose time. The amount of dissolved formaldehyde was 67.5 $\pm$ 9.5% in Ringer's solution when injection dose time was controlled about 7hrs. An adsorption trap was designed for preventing formaldehyde and microorganisms to be permeated into Ringer's solution. The adsorption trap was packed with 0.4g of active carbon (60/80 mesh) in a sterilized plastic tube (7.79 cm length, 0.46 cm i.d.) and both ends were packed with glass wool. Devised infusion set equipped with the adsorption trap showed 99.9% of removal efficiency for formaldehyde. Microorganism numbers detected on sterilized water for injection and 5% dextrose infusion used in the hospital were 2,695 $\times 10^3$ cells/l and 4,190 $\times 10^3$ cells/l, respectively. Removal efficiency by the adsorption trap was 92.3 $\pm$ 8.5% as for microorgnisms.

Eleven children with gastroesophageal reflux disease underwent fundoplication. Eight had neurological impairment, two had hiatal hernias and one had a history of esophageal repair for esophageal atresia. The most common and significant symptom was vomiting(81.8 %), followed by recurrent respiratory infections(72.7 %) and failure to thrive(72.7 %). The most common diagnostic tool was 24 hour esophageal pH study, which showed pH less than 4 for more than 10 % of the total recorded time in 6 of 9 patients. Nissen fundoplication was performed in 10 patients. Thal fundoplication was carried out in one patient with esophageal atresia. Stamm gastrostomy was added for nutritional and/or swallowing problem in all 8 patients with neurological impairment. The median follow up period was 13 months. There was one late death of unrelated cause and one recurrence. The quality of life after antireflux surgery was greatly improved. Antireflux surgery should be done if indicated, and a simultaneous gastrostomy considered in a patient with neurological impairment.

Coronavirus is an enveloped virus with positive-sense single-stranded RNA. Coronavirus infection in humans mainly affects the upper respiratory tract and to a lesser extent the gastrointestinal tract. Clinical symptoms of coronavirus infections can range from relatively mild (similar to the common cold) to severe (bronchitis, pneumonia, and renal involvement). The disease caused by the 2019 novel coronavirus (2019-nCoV) was called Covid-19 by the World Health Organization in February 2020. Face-to-face communication and consistent exposure to body fluids such as blood and saliva predispose dental care workers at serious risk for 2019-nCoV infection. As demonstrated by the recent coronavirus outbreak, information is not enough. During dental practice, blood and saliva can be scattered. Accordingly, dental practice can be a potential risk for dental staff, and there is a high risk of cross-infection. This article addresses all information collected to date on the virus, in accordance with the guidelines of international health care institutions, and provides a comprehensive protocol for managing possible exposure to patients or those suspected of having coronavirus.

Although Mycoplasma pneumoniae pneumonia (MPP) has been generally susceptible to macrolides, the emergence of macrolide-resistant MPP (MRMP) has made its treatment challenging. MRMP rapidly spread after the 2000s, especially in East Asia. MRMP is more common in children and adolescents than in adults, which is likely related to the frequent use of macrolides for treating M. pneumoniae infections in children. MRMP is unlikely to be related to clinical, laboratory, or radiological severity, although it likely prolongs the persistence of symptoms and the length of hospital stay. Thereby, it causes an increased burden of the disease and poor quality of life for the patient as well as a societal socioeconomic burden. To date, the only alternative treatments for MRMP are secondary antimicrobials such as tetracyclines (TCs) or fluoroquinolones (FQs) or systemic corticosteroids; however, the former are contraindicated in children because of concerns about potential adverse events (i.e., tooth discoloration or tendinopathy). A few guidelines recommended TCs or FQs as the second-line drug of choice for treating MRMP. However, there have been no evidence-based guidelines. Furthermore, safety issues have not yet been resolved. Therefore, this article aimed to review the benefits and risks of therapeutic alternatives for treating MRMP in children and review the recommendations of international or regional guidelines and specific considerations for their practical application.

Bovine viral diarrhea Virus (BVDV) infections cause respiratory, gastrointestinal, and reproductive problems, such as infertility, abortion, stillbirth, and sickly offspring. Many countries have reduced the economic damage through the application of different control programmes, and some have successfully eradicated BVD. Detection and elimination of cattle persistently infected (PI) with BVDV is important for BVD eradication because PI cattle are a main source of BVD transmission. In this study, the prevalence of Korean native cattle persistently infected (PI) with BVDV was investigated and determined in 49 farms with 3,050 cattle. The all samples were collected by ear notch sampling. Korean native cattle with initial positives on antigen-ELISA (Ag-ELISA) were sampled again after 3~4 weeks and cattle with second positives in both Ag-ELISA and immunohistochemistry (IHC) were identified as PI cattle. Among the 49 farms, 14 (28.6%) farms had at least more than one PI cow and 21 (0.69%) of 3,050 cattle were determined as PI cattle. As a result of this work, it is suggested that national BVD eradication program is required to reduce economic losses by BVDV infection in Korean cattle industries.

Breast implant insertion is one of the most commonly used methods for breast reconstruction after total mastectomy. However, infection is a common postoperative complication of implant insertion. In most cases, these infections can be managed with antibiotics and supportive therapy. However, severe septic conditions, such as toxic shock syndrome (TSS), can sometimes occur. TSS is an extremely rare but life-threatening complication, for which early diagnosis and proper management play a crucial role in determining patients' outcome. Although only 16 cases of TSS after breast implant insertion have been reported in the literature, most of those cases involved a serious clinical course. The reason for the seriousness of the clinical course of TSS in these cases is that the initial impression and presentation of these patients are nonspecific, and patients can easily be misdiagnosed as having a simple upper respiratory infection, causing the underlying condition to be neglected. Herein, we present two patients who were diagnosed with TSS after receiving breast reconstruction surgery via a silicone implant after total mastectomy. Both patients were misdiagnosed at the initial examination since they showed no local infectious signs on the postoperative wound.
