SM was first used during the First World War and it is still considered one of the major chemical weapons recently used by non-state actors in Syria and Iraq. In case of SM exposure, medical treatment of SM-induced lesions is symptomatic because no antidote or causal therapy does exist even though SM is very well known for over 100 years. However, clinical management in intensive care medicine of SM victims have improved since the 1980s, this study which is one of the largest recent SM-exposed case series since that time is important for the contribution to the clinical experience.

Because of spore formation, Bacillus anthracis is considered the most resistant biological warfare agent known. The present study aimed to assess and compare well-known decontamination routes to inactivate the spores on daily-use environmental tools contaminated previously. To simulate the agent, Bacillus atrophaeus was used. Various environmental samples (such as tile, fabric clothing, wood, protective suit, glass, paper, soil, water, plastic, and metal) that may be contaminated after a biological incident were used as test carriers and inoculated with B. atrophaeus. Sodium hypochlorite, free chlorine, autoclaving, ethylene oxide, hydrogen peroxide, ultraviolet irradiation, and boiling decontaminated the samples. Glutaraldehyde (2%) and free chlorine solution (10,000 mg/L) were also found to be effective in decontaminating the samples and are recommended as alternatives to the use of sodium hypochlorite solution. Soil, tile, paper, and metal were determined to be the most difficult materials to decontaminate. It was concluded that 5% hypochlorite adjusted with acetic acid might also be used for decontamination. Decontamination strategies to reduce contamination of the environment by biological warfare agents need to be applied to mitigate the number of victims, in terms of prominent characteristics like cost-effectiveness and user-friendliness.

Chronic hepatitis C virus (HCV) infection is associated with several extrahepatic syndromes. The principal types of renal disorders associated with chronic HCV infection are cryoglobulinemia or noncryoglobulinemic membranoproliferative glomerulonephritis (MPGN). Interferon-alpha (IFN-alpha) may precipitate or exacerbate the occurrence of MPGN. Our patient was a 32-year-old man who tested positive for HCV in July 1997. The patient was treated with IFN-alpha in another medical center for 6 months because his liver biopsy showed chronic active hepatitis. In December 1998, he applied to our clinic for a follow-up examination. The level of aspartate aminotransferase (AST) was 44 U/L, and that of alanine aminotransferase (ALT) was 69 U/L. HCV RNA was positive in serum, and chronic HCV infection was detected by liver biopsy. IFN-alpha therapy (5 million U/day) was administered for 6 months longer. In May 1999, the patient came to our polyclinic with edema of the feet and legs. We detected proteinuria, serum cholesterol of 269 mg/dl, AST of 50 U/L, ALT of 41 U/L, serum total protein of 3.4 g/dl, serum albumin of 1.2 g/dl, positive cryoglobulin, and urine protein of 9.84 g/day. Cryoglobulinemic MPGN was suspected and kidney biopsy was performed, resulting in a diagnosis of minimal change disease (MCD).

Disaster is defined as the holistic state of natural or human-induced events that develop suddenly, whose controllability requires a systematic approach, which interrupts or stops social life and causes loss of life, property and often cannot be overcome with local capacity. Biological disasters can be human-induced as well as naturally infectious diseases and epidemiological emergencies. Considering the potential of the 21st century, biological disasters have played a role in influenza infections such as Swine Flu (H1N1), Bird Influenza (H5N1), and the Coronavirus family. Considering the disasters in which medical CBRN agents are effective, we evaluated the data in this study to determine the risk management of biological disasters. Since the World Health Organization (WHO) declared a pandemic on March 11, 2020, the first 15 countries are included in the list based on the total cumulative order of the cases and the 12-week case of SARS-CoV-2 in the first quarter of 2021. We tried to evaluate the analysis of data, mortality rates, and the point reached in vaccination within this timeline to provide an overview of 2021 in this research study.
