Impacts of Social Distancing During the COVID-19 Outbreaks in Korea: Level 1 Trauma Center Data of Domestic Incidents and Intentional Injury

Objectives@#As a protective measure to slow down the transmission of coronavirus disease 2019 in Korea, social distancing was implemented from February 29th , 2020. This study aimed to evaluate the prevalence of domestic incidents and intentional injury during March 2020 when social distancing was in effect. @*Methods@#There were 12,638 patients who visited the Level 1 trauma center of Chungnam province with injuries from domestic incidents, familial discord, and intentional injury. The prevalence of injuries during March 2020 was compared with the average of the previous 5 years, and the average for every March between 2015 and 2019. @*Results@#The prevalence of domestic incidents in March 2020 was significantly higher than the 5-year average, and the average for every March from 2015 to 2019 (p < 0.001). Familial discord (p = 0.002) and intentional injury (p = 0.031) were more frequently observed in March 2020. Adolescents showed a markedly higher level of intentional injury in March 2020 than in both the 5-year average (p = 0.031), and average for every March over the previous 5 years (p = 0.037). @*Conclusion@#The prevalence of domestic incidents and intentional injury were significantly higher during the period of social distancing in Korea. There is a need for social consensus, better policies, and psychological support services, especially if faced with a second or third wave of coronavirus disease.

Genetic and Clinical Characteristics of Multiplex Schizophrenia Families / 신경정신의학

OBJECTIVES: This study aims at exploring genetic and clinical characteristics of multiplex Korean families with schizophrenia. METHODS: Thirty-three families having two or more schizophrenics by DSM-IV criteria within the second degree relatives were obtained from the clinics of general hospitals and mental hospitals. Sixty-nine affected and forty-five unaffected subjects from these families were interviewed using Korean version of Diagnostic Interview for Genetic Studies. Krawieka Rating Scale and The Schedule for the Deficit Syndrome were also applied for further evaluation of psychopathologies of the patients. Patterns of inheritances of the disease were analyzed by the inspection of the pedigrees. Parent-of-origin effect was evaluated by the comparison of the occurrence rate and the clinical characteristics between the subgroups of maternal and paternal origins. RESULTS: There were similar rates of maternal and paternal transmission in the families for which unilineal transmission of the disease was estimated. Only one family showed bilineal transmission. Observed patterns of transmission were not compatible with the recessive single locus model or sex-linked model. The most frequently observed non-schizophrenic disorders in these families were personality disorders/traits of schizophrenia spectrum. We could not find any clinical characteristics which might be unique to the patients from multiplex families. Parent-of-origin effect was not suggested. CONCLUSION: This study provides preliminary clinical and genetic data on the multiplex schizophrenia families which could be used for the determination of the genetic parameters and the boundaries of the phenotype in the linkage analyses.

A Case of Crohn's Disease Showing a Skin Lesion with a Cobblestone-like Appearance in the Perianal Region

Crohn's disease, a chronic relapsing, multisystemic, inflammatory disorder, may involve any part of the gastrointestinal tract and shows a cobblestone-like appearance on intestinal mucosa. There are also extraintestinal features, including lesions of the skin, eye, and joints. Ulcers, fissures, sinus tracts, abscesses, and vegetant plaques have been reported for the perianal skin lesions of Crohn's disease. We experienced a case of Crohn's disease in a 21-year-old Korean female showing a skin lesion with a cobblestone-like appearance in the perianal region.
