Monkeypox: A Comprehensive Review

The 2022 multi-country monkeypox outbreak in humans has brought new public health adversity on top of the ongoing coronavirus disease 2019 (COVID-19) pandemic. The disease has spread to 104 countries throughout six continents of the world, with the highest burden in North America and Europe. The etiologic agent, monkeypox virus (MPXV), has been known since 1959 after isolation from infected monkeys, and virulence among humans has been reported since the 1970s, mainly in endemic countries in West and Central Africa. However, the disease has re-emerged in 2022 at an unprecedented pace, with particular concern on its human-to-human transmissibility and community spread in non-endemic regions. As a mitigation effort, healthcare workers, public health policymakers, and the general public worldwide need to be well-informed on this relatively neglected viral disease. Here, we provide a comprehensive and up-to-date overview of monkeypox, including the following aspects: epidemiology, etiology, pathogenesis, clinical features, diagnosis, and management. In addition, the current review discusses the preventive and control measures, the latest vaccine developments, and the future research areas in this re-emerging viral disease that was declared as a public health emergency of international concern.     

Anaphylaxis: lesson learned from five cases

Anaphylaxis is a severe hypersensitivity reaction. Its clinical manifestations vary, affecting several organs at once. Skin symptom is the most frequent manifestation; however, diagnosis of anaphylaxis will only be established when involving one or both vital organs, which are cardiovascular and respiratory system. Other symptom, such as that involving central nervous system or gastrointestinal tract, may accompany. We present five cases of anaphylaxis which vary in onset of symptoms, allergen, degree of severity, therapeutic response and clinical manifestation. Anaphylactic reaction to drugs in these cases is mainly manifested as anaphylactic shock and reaction to food allergen causing obstruction of respiratory tract. Four anaphylactic events occurred at home and only one occurred in a hospital, thus education on anaphylaxis to general community is very important, especially for the patients and their families. Prompt medical assistance in patients with anaphylactic symptoms determines their therapeutic response. Skin test prior to administration of cephalosporin does not give negative predictive value toward anaphylactic event.
