The Philippine Journal of Otolaryngology Head and Neck Surgerypreviously co published two guest editorials, on “Reducing the Risks of Nuclear War— the Role of Health Professionals”¹and “Time to Treat the Climate and Nature Crisis as One Indivisible Global Health Emergency”²that addressed dual potentially catastrophic concerns that both place us “on the brink.”³

By co-publishing these guest editorials, the Philippine Journal of Otolaryngology Head and Neck Surgery joined the call for “health professional associations to inform their members worldwide about the threat to human survival and to join with the International Physicians for the Prevention of Nuclear War (IPPNW) to support efforts to reduce the near-term risks of nuclear war.”¹As enumerated in the editorial,¹we urged three immediate steps that should be taken by nuclear-armed states and their allies: 1) adopt a no first use policy;⁴2) take their nuclear weapons off hair-trigger alert; and 3) urge all states involved in current conflicts to pledge publicly and unequivocally that they will not use nuclear weapons in these conflicts.It is alarming that noprogress has been made on these measures.

Thus, on our 44th Anniversary, we join over 150 scholarly scientific journals worldwide in co-publishing another Guest Editorial on “Ending Nuclear Weapons, Before They End Us.”⁵We call on the World Health Assembly (WHA) to vote this May on re establishing a mandate for the World Health Organization (WHO) to address the consequences of nuclear weapons and war,6and urge health professionals and their associations (including otolaryngologists – head and neck surgeons, all surgeons and physicians, and the Philippine Society of Otolaryngology – Head and Neck Surgery, Philippine College of Surgeons, Philippine College of Physicians,
Philippine Academy of Family Physicians, Philippine Pediatric Society, Philippine Obstetrical and Gynecologic Society, Philippine Society of Anesthesiology, Philippine College of Radiology, Philippine Society of Pathologists, other specialty and subspecialty societies, and the Philippine Medical Association) to urge the Philippine Government to support such a mandate and support the new United Nations (UN) comprehensive study on the effects of nuclear war.⁷

Phosgene is not only a dangerous asphyxiating chemical warfare agent, but also an important chemical raw material, which is widely used in chemical production. According to statistics, there are more than 1 000 phosgene production enterprises in China, with an annual production volume of more than 3 million tons and hundreds of thousands of employees. Therefore, once the leakage accident occurs during production, storage and transportation, it often causes a large number of casualties. In the past 20 years, phosgene poisoning accidents in China have occurred from time to time, and due to the weak irritation, high density, and high concentration of phosgene at the scene of the accident, it often results in acute high-concentration inhalation of the exposed, triggering acute lung injury (ALI), and is very likely to progress to acute respiratory distress syndrome (ARDS), with a mortality rate up to 40%-50%. In view of the characteristics of sudden, mass, concealed, rapid and highly fatal phosgene, and the mechanism of its toxicity and pathogenicity is still not clear, there is no effective treatment and standardized guidance for the sudden group phosgene poisoning. In order to improve the efficiency of clinical treatment and reduce the mortality, this paper has summarized the pathophysiological mechanism of phosgene poisoning, clinical manifestations, on-site treatment, research progress, and innovative clinical therapies by combining the extensive basic research on phosgene over the years with the abundant experience in the on-site treatment of sudden mass phosgene poisoning. This consensus aims to provide guidance for the clinical rescue and treatment of patients with sudden mass phosgene poisoning, and to improve the level of treatment.

Hip firearm injuries are rare injuries that could lead to serious complications, such as posttraumatic hip arthritis and coloarticular fistula. We report a case of a 25-year-old male who sustained a pelvic injury caused by a single bullet which led to a bilateral acetabular fracture, concomitant with a colon injury treated on an emergency basis by a diverting colostomy; acetabular fractures were treated conservatively by traction. After the patient recovered from the abdominal injury, he was presented with bilateral hip pain and limited motion; plain radiographs showed bilateral hip arthritis with proximal migration of the femoral head and bilateral acetabular defect classified as Paprosky type ⅢA. Reconstruction of the hips was performed using the same technique: impaction bone grafting for acetabular defect reconstruction and a reversed hybrid total hip arthroplasty (THA) 6 months apart. The patient presented with loosening of the left THA acetabular cup 3 years later, which was revised; then he presented with a discharging sinus from the left THA with suspicion of coloarticular fistula, which was confirmed using CT with contrast material. A temporary colostomy and fistula excision were performed, and a cement spacer was applied to the hip. After clearing the infection, a final revision THA for the left hip was performed. Treating post-firearm hip arthritis by THA is challenging, especially in the situation of neglected cases with the presence of an acetabular defect. Concomitant intestinal injury increases the risk of infection with the possibility of coloarticular fistula formation, which could present later. Working with a multidisciplinary team is paramount.

On December 31, 2018, an incident occurred where a doctor was attacked and killed by a patient carrying a lethal weapon in the outpatients' clinic of the psychiatric department of a tertiary general hospital. The suspect was diagnosed with bipolar affective disorder (manic depressive disorder) and has been hospitalized and cared for in the psychiatric ward of this hospital. This incident illustrates the necessity of more active cures and therapeutic intervention for mental patients with intellectual developmental disorders who require treatment considering the fact that a radical outcome has been caused by such a patient. However, on the other hand, there is also a need for an approach and analysis from the perspective of crime prevention for all medical departments. The reason for this is that even a tertiary general hospital equipped with the largest human resources, medical devices, facilities, and so forth, is susceptible to violence. As for illegal actions perpetrated against health and medical service personnel in medical institutions, such as verbal abuse, assault, injury, etc. there have neither been understanding shown for the current extent of damage in detail, nor discussions of active institutional improvement related to the seriousness of the act. It can be said that violence in the field of medical treatment is a realm requiring serious discussion and appropriate remedial actions. This is because when such incidents take place, if a patient who is supposed to get treatment from the damaged health care provider is in an urgent situation or on the waiting list of serious cases, he or she could suffer serious damage caused by deprivation of treatment opportunity, or secondary damage might be caused to the patient and/or a guardian who can hardly have an opportunity to take action. Accordingly, in this review, we would like to help create the necessary conditions for both health and medical service personnel and patients/guardians, respectively, to provide and receive medical treatment in a more secure environment. Therefore, objective assessment of the institution and issues relating to this aforementioned incident and general cases of violence occurring in medical institutions, and by suggesting legal and institutional improvements and solutions.

PURPOSE: The aims of this study were to evaluate the dentist's awareness and the actual status of infection control of noncritical dental instruments. MATERIALS AND METHODS: 40 dental clinics in Daejeon, South Chungcheong, North Chungcheong and North Jeolla provinces were surveyed. The questionnaire was delivered to the dentists belonging to those clinics, and the awareness and the practice of infection control were examined. The microbial contamination on the surface of five noncritical instruments (impression gun, light curing unit, 3-way syringe, shade guide, and dental floss dispenser) used by them was measured with an ATP luminometer. Correlation analysis between the awareness and the actual state of infection control was conducted. RESULTS: Awareness and frequency of infection control was highest in the 3-way syringe. Surface disinfection using disinfectant was most frequent in all instruments. 3-way syringes and shade guides were less contaminated than impression guns, light curing units, and dental floss dispensers. CONCLUSION: 3-way syringes had a significant correlation between user awareness of infection control and surface contamination, and the higher awareness, the lower the contamination measurement was shown.

While radioactive isotope analysis has proved to be a useful method in disciplines such as archaeology and forensic anthropology, more recently, radiocarbon dating has allowed for a more nuanced biological profile of human skeletal remains. Radiocarbon dating has been made possible by the above ground nuclear bomb test conducted in 1963, which raised the level of atmospheric radiocarbon concentration to almost twice the natural level. Because the annually measured tropospheric ¹⁴C concentrations are integrated into the bomb peak curve, the time of birth and death of an individual can be estimated by comparing the radiocarbon content of a skeletal sample to the bomb-curve value. In July 2017, about 1,000 skeletal remains were excavated at the construction site of Sokcho. For medico-legal purposes, we conducted anthropological and odontological examinations of all the human remains. We then conducted the radiocarbon analysis on seven femora (head and body portions), five mandibular teeth, and soil from the site through a request to the Korea Institute of Geoscience and Mineral Resources. The results demonstrated that the estimated year of birth or death was prior to the 1950s. Due to the diverse distribution of results, we deduced that the human remains were from the local mass grave. This study supports and suggests the use of radiocarbon dating more frequently in the analysis of human skeletal remains.

We have examined isolation and identification protocols for three virus simulant candidates to biological warfare agents. MS2 phage, a simulant for yellow fever virus and Hantaan virus, was propagated using as a host an E. coli strain with F pilus. MS2 phage genome was examined by reverse transcription and polymerase chain reaction (RT-PCR). Coat protein of the phage preparation was examined by SDS-polyacrylamide gel electrophoresis (SDS-PAGE) and mass spectrometric analysis. Cydia pomonella granulosis virus (CpGV) is a virus simulant candidate to smallpox virus. CpGV was isolated from a commercialized CpGV pellet. In this study, we developed new isolation and identification protocols for CpGV. One disadvantage of using CpGV is that it is not easy to determine viability of the virus. Here, we have included T4 phage as an alternative. We established a high titer production protocol and developed an easy genome identification protocol that does not require purified phage DNA. Stability of these virus preparations was also examined under various storage conditions. When the virus preparations were not subjected to freeze drying, MS2 phage was most stable when it was stored in liquid nitrogen but unstable at 4℃. In contrast, T4 phage was most stable when it was stored at 4℃. CpGV was stable at −20℃ but not at 4℃. Stability during or after freeze drying was also investigated. The result showed that 70~80% MS2 survived the freeze drying process. In contrast, only about 15% of T4 phage survived during the freeze drying. CpGV was found to be degraded during freeze drying.
