  • In mass casualty situation due to radiological accidents, it is important to start aggressive management with rapid triage decisions. External contamination needs immediate decontamination and internal contamination should be treated with special expertise and equipment to prevent the rapid uptake of radionuclides by target organs. Acute radiation syndrome shows a sequence of events that varies with the severity of the exposure. More severe exposures generally lead to more rapid onset of symptoms and severe clinical findings. After the massive exposure, various systems of the body reflect their severe damages that can lead to death within hours or up to several months. The disease progression has classically been divided into four stages: prodromal, latent, manifest illness, and recovery or death. Three characteristic clusters of symptoms including the hematopoietic syndrome, the gastrointestinal syndrome and the cerebrovascular syndrome are all associated with the acute radiation syndrome. The standard medical management of the patients with a potentially survivable radiation exposure includes good medical, surgical and supportive measures. Specific treatment with cytokines and bone marrow transplantation should be considered. The management of internal contamination is much the same as the treatment of poisoning. The standard decontamination should be applied to reduce uptake, and the chelating agents can be administered to enhance the clearance of radioisotopes. Radioactive iodine ($^{131}I$) as one of the nuclear fission products can increase the incidence of thyroid cancer in children. Potential benefit of potassium iodide prophylaxis is greater especially in neonates, infants and small children.

  • Objectives: The goal of the study was to investigate the clinical effects of amoxicillin-clavulanic acid (500+125 mg) with metronidazole 400 mg administered three times daily (Group I) versus azithromycin 500 mg administered once daily and with metronidazole 400 mg three times daily (Group II) for the prevention of postoperative infection following mandibular third molar surgical removal. Materials and Methods: The study design was a single-center prospective study. Patients who reported to the Department of Oral and Maxillofacial Surgery between February 2015 and January 2017 for removal of mandibular third molar were screened, and 108 patients were chosen. One surgeon carried out all procedures. Patients were prescribed antibiotics until the two groups contained a similar number of cases. Results: Our data showed that Group II had fewer incidences of surgical site infection, but with no statistical significance. Conclusion: Although both treatments are used routinely after removal of the mandibular third molar, neither is significantly better than the other.

  • Purpose: Adolescents who experienced the alcohol consumption have gradually increased. Adolescence is a critical period of the neural plasticity in the brain. Neural plasticity is mediated by neurotrophins and has an impact on cognitive function. Environmental enrichment ameliorates the cognitive function and increases neurotrophins. Thus, we investigated the neuroprotective effect of environmental enrichment on ethanol induced cognitive impairment in adolescent rats. Methods: The ethanol groups and the controls groups were injected with ethanol (0.5g/kg) and phosphate buffered saline, respectively, through intraperitoneal from 28th day of birth for 11 days. The environmental enrichment groups were provided larger cages containing toys than the standard cage. Passive avoidance test and Y-maze test were performed to evaluate the spatial memory. Results: Environmental enrichment+ethanol group showed higher alterations than the standard environment+ethanol group in Y-maze test (p<.05). In hippocampus, The environmental enrichment+ethanol group showed significantly higher level of the number of c-fos positive celsl and density of tropomyosin receptors kinase B receptor than the standard environment+ethanol group (p<.05). Conclusion: So, we suggested that the environmental enrichment played a role as a prophylaxis for prevention of memory impairment induced by ethanol exposure in adolescence.

  • Respiratory syncytial virus (RSV) is a major cause of respiratory infection in children. Most of the pediatric population have RSV infection before the age of 2, and recurrent infections are common even within one season. Chronic lung disease, prematurity, along with congenital heart disease (CHD) are major risk factors in severe lower respiratory infection. In hemo-dynamically significant CHD patients with RSV infection, hospitalization is usually needed and the possibility of treatment in intensive care unit and the use of mechanical ventilator support are known to increase. Therefore the prevention of RSV infection in CHD patients is mandatory. The current standard for RSV prevention is immunoprophylaxis by palivizumab. Immunoprophylaxis is recommended monthly in hemodynamically significant CHD patients, up to 5 months. Motabizumab, a second generation drug and newly developing RSV vaccines are also expected to play a key role in RSV prevention in the future. The prophylaxis of RSV infection in CHD patients is cost-effective in both the medical aspect of the patients as well as the socio-economic aspect. Therefore an effort to promote prevention should be made by not only the family of the patients but also by the government.

  • Respiratory syncytial virus (RSV) is a main cause of hospitalization for bronchiolitis and pneumonia in infants worldwide. Children with hemodynamically significant congenital heart disease (HS-CHD), as well as premature infants are at high risk for severe RSV diseases. Mortality rates for CHD patients hospitalized with RSV have been reported as about 24 times higher compared with those without RSV infection. Recently with advances in intensive care, mortality rates in CHD patients combined with RSV have decreased below 2%. The requirements of intensive care and mechanical ventilation for CHD patients with RSV infection were still higher than those without RSV infection or with non-CHD children. RSV infection has frequently threatened CHD infants with congestive heart failure, cyanosis, or with pulmonary hypertension. As a progressive RSV pneumonitis in those infants develops, the impairment of oxygen uptake, the breathing workload gradually increases and eventually causes to significant pulmonary hypertension, even after the operation. Preventing RSV infection as much as possible is very important, especially in infants with HS-CHD. A humanized monoclonal antibody, palivizumab, has effective in preventing severe RSV disease in high-risk infants, and progressive advances in supportive care including pulmonary vasodilator have dramatically decreased the mortality (<1%). Depending on the global trend, Korean Health Insurance guidelines have approved the use of palivizumab in children <1 year of age with HS-CHD since 2009. Korean data are collected for RSV prophylaxis in infants with CHD.

  • The authors made an attempt to trephinize in a cow with frontal sinusitis caused by bacterial infection after dehorning. Combination therapy with irrigating solution, antibiotics and proteolytic agent was effective in the patient. As it takes for a long duration to cure the patient, it is considered that complete prophylaxis such as preservation and protection for dehorned area is desirable.

  • Seborrheic dermatitis is characterized by the appearance of red, flacking, greasy lesions in regions rich in sebaceous glands. There are various opinions about the relation between seborrheic dermatitis and dandruff. Considering all available data, we consider seborrheic dermatitis and dandruff to be differing severity manifestations of similar origin. The known etiologies of seborrheic dermatitis are the abnormality of lipid and hormnes, Malassezia species, immune response. We recently focus on the relation between seborrheic dermatitis and HIV positive and AIDS patients, seborrheic dermatitis and neurological disease. The treatments of seborrheic dermatitis include topical treatments, oral treatments. There are non-specific agents, antifungal medication, corticosteroids in the topical treatments. Narrow band UVB and oral medications are known as the prophylaxis of seborrheic dermatitis but we need further study. In traditional korean medicine, the literature studies and case reports have been published. But we don't know what herbal medicine has antifungal effect against Malassezia species. So we should discriminate herbal medicines which have antifungal effect against Malassezia specieses. Then we could treat seborreic dermatitis by traditional korean medicine effectively.

  • The acute toxicity of the combined vaccine (KGCC-95VI) for the prophylaxis against Japanese encephalitis and Hantaan virus infection. recently developed by Korea Green Cross Corporation, was investigated. KGCC-95VI was administered to the Balb /c mice in two routes, orally and subcutaneously, and into the New Zealand White rabbits subcutaneously. $LD_{50}$ was not accessible as there were no deaths in the group treated even at a dose 800 times the expected clinical dose in both animal species. Between the treated and control groups there were no statistically significant differences in body weight changes and clinical signs during the 14-day observation period, and no pathological gross findings. Accordingly KGCC-95VI is considered not to have the acute toxicity in mice and rabbits.

  • Purpose: In the Korean armed forces, vaccination against tetanus is done when personnel join the military service, but we do not know how many military personnel are vaccinated and how many soldiers have protection against tetanus. We performed a qualitative analysis of the tetanus antibody in Korean military personnel by using the TQS (Tetanus Quick Stick) Methods: This study used a prospective collection method for military personnel visiting to the emergency department of a tertiary armed forces hospital from July 2005 to January 2007. We performed an analysis by using the TQS and asked whether the personnel had been inoculated during military service. Results: The number of enrolled military personnel was 474. Among them, 412 had been vaccinated against tetanus after entering the military service. The positive rate of TQS was 91.3% (373 patients) after vaccination for tetanus. Conclusion: Many military personnel were inoculated with tetanus toxoid during military service and have protective antibodies for tetanus. According as TQS should be used for military personnel who visit the emergency department of an armed forces hospital. Also, anti-tetanus immunoglobulin should not normally be used a positive TQS for tetanus prophylaxis.
