Gua Sha, An Asian Traditional Therapy That Could Mimic Physical Injury / 대한법의학회지

Gua Sha is a traditional Asian medicine with different names in many Asian countries. It is a treatment to scrape the petechiae of the skin with ointment. It has generally been administered to patients with upper respiratory infections, heat syndrome, and pain. Herein, we report the case of a 31-year-old Cambodian man who was found dead at a farm accommodation. During the autopsy, multiple linear intradermal hemorrhages without subcutaneous damage were observed in the upper chest and both shoulders. The cause of death was sudden unexpected nocturnal death syndrome because he was a young Asian man who died while sleeping without specific findings. Since it is an unfamiliar traditional medicine in Korea compared to other Asian countries, forensic officers without background knowledge about Gua Sha initially suspected that he was severely assaulted or pressed against a particular object enough to cause crush asphyxia. Because of the difficulty of going to the hospital during the coronavirus disease 2019 pandemic, Gua Sha was used to treat headaches and mild fever. Therefore, this case shows that understanding the culture of other countries could be helpful for investigations especially with the increase of multicultural families in Korea.

Early diagnostic value of the antimycoplasma antibody (IgM) in Mycoplasma pneumoniae pneumonia: A single-center study in 2015

PURPOSE: Recently, the incidence of refractory Mycoplasma pneumoniae (MP) pneumonia has increased in Korea. Given that its early diagnosis is helpful in selection of the treatment, this study aimed at investigating the value of the antimycoplasma antibody (IgM) for early diagnosis of MP pneumonia. METHODS: A total of 315 children admitted with MP pneumonia from September 2015 to May 2016 were investigated with the IgM and polymerase chain reaction (PCR) for the diagnosis of MP pneumonia. Specifically, patients were grouped into nonrefractory respiratory MP and refractory MP groups according to their response to macrolide therapy. RESULTS: In the 44 PCR-negative seroconversed children, seroconversed IgM was more frequent in the refractory MP group compared with the nonrefractory respiratory MP group with statistical significance (P<0.001). In the 264 IgM-positive children, the time of antibody reaction was more delayed in the refractory MP group compared to the nonrefractory respiratory MP group with statistical significance (P<0.001). CONCLUSION: This study showed that there was a higher incidence of seroconversed IgM and delayed antibody reaction in the refractory MP group. In children with suspect MP pneumonia, follow-up studies of antibody are necessary, even through initial antibody and PCR showed negative findings. In addition, this result may suggest that the diagnosis of refractory MP pneunomia will be helpful in establishing the strategy of the treatment.
