BACKGROUND: This research investigated the association between facial flushing after drinking and alcohol-induced biomarker abnormalities. METHODS: This retrospective study included 374 male drinkers who visited the department of Family Medicine of Chungnam National University Hospital between January and December of 2010. The participants were classified into two groups: the flushing group (n = 107) and the non-flushing group (n = 267). The biomarkers assessed were % carbohydrate-deficient transferrin (CDT) and gamma glutamyl transferase (rGTP). The upper limits of %CDT and rGTP were set as 2.47 and 50, respectively. The receiver operating characteristic (ROC) curve was used to obtain the cut-off value for the amount of drinking that caused abnormal %CDT and rGTP levels in the two groups. The sensitivity and specificity of the cut-off drinking amount for %CDT and rGTP abnormalities were analyzed in each group. RESULTS: In the flushing group, the cut-off value for alcohol-induced %CDT abnormality was 3.38 drinks (1 drink: 14 g of alcohol) per week, with sensitivity of 77.8% and specificity of 70.4%. In the non-flushing group, the cut-off value was 11.25 drinks per week, with sensitivity of 62.2% and specificity of 69.6%. The cut-off value for the amount of alcohol that induced rGTP abnormality was 3.38 drinks per week in the flushing group, with sensitivity of 68.0% and specificity of 76.8%, whereas it was 8.75 drinks in the non-flushing group, with sensitivity of 71.1% and specificity of 66.7%. The area under the ROC of the drinking level was 0.726 in the flushing group and 0.684 in the non-flushing group for %CDT. For rGTP, the value was 0.738 in the flushing group and 0.718 in the non-flushing group. CONCLUSION: The weekly drinking amount required to induce biomarker abnormalities was lower in the flushers than in the non-flushers.

PURPOSE: Although alcohol is frequently present in injury patients, whether it exacerbates injury and whether tolerance to alcohol changes such a relationship is less clear. We investigated alcohol's role in injury and the effect of alcohol on the severity of injury. METHODS: This prospective study was performed from July 20, 2004, to October 20, 2004, at five university hospital emergency departments (ED). We studied trauma patients, excluding pediatric patients (15 year old and under), alcohol consumption over the 6 hours prior to visiting the ED and continuous drinking after injury. Patients were screened by blood tests for the presence of alcohol and were classified into two groups by alcohol consumption. The injury severity was measured by using the Abbreviated Injury Scale (AIS) and the Injury Severity Score (ISS). RESULTS: The study enrolled 361 injured patients, of whom 105 were intoxicated and 256 were not intoxicated. Alcohol consumption was significantly larger in males than in females and in cases involving violence. The injury severities were not correlated with alcohol consumption significantly between intoxicated patients and not intoxicated patients. were not significantly different. However, the number of days in the intensive care unit and the mortality correlated with alcohol consumption. In patients with severe injuries (ISS> or =15, AIS> or =3), alcohol consumption was correlated with severity of the injury. CONCLUSION: Alcohol intoxication is not associated with injury severity. But in patients with severe injuries (ISS> or =15, head AIS> or =3), alcohol consumption was correlated with injury severity.

Purpose: Acute organophosphate (OP) poisoning may be monitored by measuring the acetylcholinesterase (AChE). It is important to assess severity and establish prognostic tests in the early stage of OP poisoning. The aim of this study was to look at the relationship between various clinical aspects of the OP poisoning, prognostic indicators of OP poisoning including Simplified Acute Physiology Score (SAPS) 3, and the associated changes in AChE levels. Methods: Clinical data and initial AChE levels from thirty-seven patients with OP poisoning were prospectively reviewed from 12 teaching hospitals in South Korea from August 2005 to July 2006. Clinical manifestations at the time of arrival such as miosis, respiratory abnormality, salivation, urinary incontinence, GCS score, AVPU scale, need for intubation, and mechanical ventilation requirements were recorded. SAPS 3 was calculated using clinical data and laboratory results. Results: The median level of AChE was 9.8 (1.3-53.6) U/gHb. There was no significant difference in AChE levels between the groups with and without cholinergic symptoms. The median level of AChE of the patients who required intubation and those who did not were 3.5 U/gHb and it 19.7 U/gHb respectively (Mann-Whitney test; p<0.001). The AChE levels were also significantly different (p=0.007) in patients who needed mechanical ventilation compared to those who did not with AChE levels found to be 3.1 U/gHb and it was 14.8 U/gHb, respectively. Level of consciousness assessed using the AVPU scale was correlated with AChE levels (Kruskal-Wallis test; p=0.013). GCS score were correlated with AChE levels (p=0.007, Spearman's rho = 0.454). In addition, the lower the level of initial AChE, the longer the ICU stay (p=0.029, Spearman's rho=-0.380). SAPS 3 was inversely correlated with the initial AChE (p<0.001, Spearman's rho=-0.633). Conclusion: In the acute OP poisoning, low AChE levels appear to help indicate the severity of poisoning. The initial AChE level may be a useful prognostic parameter for acute OP poisoning.

Purpose: The purpose of this randomized controlled trial was to compare the effects of abdominal binder after laparoscopic cholecystectomy. Methods: From August to December 2020, 66 patients who were set to undergo cholecystectomy were selected for a prospective trial at Kangbuk Samsung Hospital, Seoul, Republic of Korea, and their clinical characteristics and postoperative surgical outcomes were evaluated. Among 66 patients, 33 patients belong to the abdominal binder group and the other 33 patients belong to the control group. Results: The average hospital stay was 2.46 ± 1.29 days, and was not significantly different between the two groups. The average postoperative pain score (visual analogue scale, 0–10) 12, 24, and 48 hours after surgery were not significantly different. However, the degree of comfort score was significantly higher for the control group patients (2.56 vs. 3.33, p < 0.001). Time to the first ambulation, walking ability, return of bowel function, time to full diet resumption, and the numbers of analgesics and antiemetics administered were not significantly different between the two groups. Conclusion No postoperative recovery benefit and no reduction in hospital stay was found in patients who used an abdominal binder while undergoing laparoscopic cholecystectomy. Statistically, between the group that used the binder and the one that did not, no significant differences in surgical outcome nor postoperative outcome were observed. The only exception was that the degree of comfort score was significantly higher in the control group. Therefore, in terms of patient benefit and convenience, wearing an abdominal binder after laparoscopic cholecystectomy is not recommended.

Idiopathic fibrosing mediastinitis is, an uncommon cause of pulmonary hypertension this is characterized by excessive fibrosis of the mediastinum with an unknown etiology. Steroid therapy has been suggested for individuals with progressive symptoms, bu there is littlet data demonstrating the efficacy of such therapy are lacking. We present a case of pulmonary hypertension secondary to a compression of a main pulmonary artery by fibrosing mediastinitis which was confirmed by a biopsy with a thoracotomy. The chest CT scan and 2D echocardiography performed before and after a trial of steroid therapy demonstrated improvement after steroid therapy.

Severe fever with thrombocytopenia syndrome (SFTS) is an emerging zoonotic disease, which causes high fever, thrombocytopenia, and death in humans and animals in East Asian countries. The pathogenicity of SFTS virus (SFTSV) remains unclear. We intraperitoneally infected three groups of mice: wild-type (WT), mice treated with blocking anti-type I interferon (IFN)-α receptor antibody (IFNAR Ab), and IFNAR knockout (IFNAR−/−) mice, with four doses of SFTSV (KH1, 5 × 105 to 5 × 102 FAID50). The WT mice survived all SFTSV infective doses. The IFNAR Ab mice died within 7 days post-infection (dpi) with all doses of SFTSV except that the mice were infected with 5 × 102 FAID50 SFTSV. The IFNAR−/− mice died after infection with all doses of SFTSV within four dpi. No SFTSV infection caused hyperthermia in any mice, whereas all the dead mice showed hypothermia and weight loss. In the WT mice, SFTSV RNA was detected in the eyes, oral swabs, urine, and feces at 5 dpi. Similar patterns were observed in the IFNAR Ab and IFNAR−/− mice after 3 dpi, but not in feces. The IFNAR Ab mice showed viral shedding until 7 dpi. The SFTSV RNA loads were higher in organs of the IFNAR−/− mice compared to the other groups. Histopathologically,coagulation necrosis and mononuclear inflammatory cell infiltration in the liver and white pulp atrophy in the spleen were seen as the main lesions in the IFN signaling lacking mice. Immunohistochemically, SFTSV antigens were mainly detected in the marginal zone of the white pulp of the spleen in all groups of mice, but more viral antigens were observed in the spleen of the IFNAR−/− mice. Collectively, the IFN signaling-deficient mice were highly susceptible to SFTSV and more viral burden could be demonstrated in various excreta and organs of the mice when IFN signaling was inhibited.
