The deep vein thrombosis had been described as the reaction of vascular inflammatory change by John Hunter in 1773, and Virchow described the pathophysiology of etiologic factors for the first time in 1856. Deep Vein thrombosis and pulmonary embolism is common disease in the North American and European countries. It was reported that deep Vein thrombosis and pulmonary embolism were associated with 300,000 to 600,000 hospitalizations for each year and that as many as 50,000 individuals die each year as a result of pulmonary embolism in the United States. In Korea, deep vein thrombosis is uncommon, complicating pulmonary embolism & renal thromboembolism are also rare, and many cases had not specific history & precipitating factor. The report is for one case of deep vein thrombosis associated with pulmonary & renal thromboembolism, who was 34-years-old, admitted to Masan Koryo hospital because of pain and edema in left lower extremity, had not specific history & precipitating factor. The thrombosis(or thromboembolism) involed his left lung & kidney, and the patient present with severe swelling of affected limb and oliguria. He underwent leg elevation under absolute bed rest and anticoagulant therapy. The significant improvement was done under medical treatment. We report one case of deep vein thrombosis with a brief of literatures.

The purpose of this study was to examine the effects of an exercise intervention for older married couples on exercise adherence and physical fitness. Thirty-six older married couples and 61 older adults participated in the study as couple and non-couple groups (CG, NCG, respectively). Participants attended an exercise class once a week and performed a home-based exercise program consisting of walking and strength exercise over eight weeks. Exercise adherence was assessed by the rate of non-absentee, walking habits (≥ 2 times/week), and strength exercise habits (≥ 6 items*2 sets/week). Physical fitness was assessed by the Senior Fitness Tests. Logistic regression analyses were conducted to obtain the CG’s odds ratios (ORs) and 95% confidence interval (CI) for non-absentee, walking habits, and strength exercise habits (reference: NCG). Analyses of covariance were used to examine the statistical difference in the degree of change (⊿) for physical fitness between CG and NCG. CG had significantly higher ORs for non-absentee and walking habits compared with NCG but there was no significant difference in the rate of strength exercise habits between the two groups. In regards to ⊿ for physical fitness, significantly higher ⊿ for upper extremity strength was observed in CG than in NCG, while there were no significant differences in ⊿ for other physical fitness items between the two groups. These results suggest that an exercise intervention for older married couples would be more useful to maintain higher participation in exercise program and walking and improving upper extremity strength.

Adipsia is a rare disorder that occurs due to damage to the osmoreceptor and not feeling thirst despite hyperosmolality. Adipsic hypernatremia can occur when there is damage to the anterior communicating artery that supplies blood to osmoreceptors, and the level of arginine vasopressin secretion varies widely. A 37-year-old woman, suffering from severe headache, was consulted to the nephrology department for hypernatremia and polyuria after clipping of a ruptured aneurysm in the anterior communicating artery. Despite her hypernatremic hyperosmolar state, she denied thirst and did not drink spontaneously. She was diagnosed adipsic hypernatremia by evaluating the osmoregulatory and baroregulatory function tests.Because adipsic hypernatremia is caused by not enough drinking water even for hyperosmolality due to the lack of thirst stimulus, the strategies of treatment are that setting the target body weight when serum osmolality is normal and have the patient drink water until patient reach the target body weight. Adipsic hypernatremia should be considered to be a rare complication of subarachnoid hemorrhage associated with an anterior communicating artery aneurysm.

Increasing importance of vaccination during coronavirus disease 2019 (COVID-19) pandemic, several vaccines were developed. Messenger RNA (mRNA) vaccines including BNT162b2 (Pfizer, New York, NY, USA; BioNTech, Mainz, Germany), mRNA-1273 (Moderna, Cambridge, MA, USA) have been disclosed side effects such as thrombocytopenia, myocarditis and headache in general. In addition, adverse effects due to autoimmune responses induced by spike glycoproteins of mRNA vaccines are rarely reported such as the Guillain-Barre syndrome, autoimmune encephalitis and so on. Herein, we report a rare case of encephalitis with new-onset refractory status epilepticus after BNT162b2 mRNA COVID-19 vaccination improved with immune therapy.

PURPOSE: The aim of this study was to investigate the independent factors associated with the registration rate for the community-based post suicidal care program in the emergency department (ED). METHODS: This prospective observational study was conducted between March and December 2013 at the academic ED at the tertiary urban hospital. During the study period, the pre-designed registry was recorded. The variables examined included the following: patients' demographic data (Sex, age, address, type of insurance, marital status, level of education, and history of previous psychiatric disease), suicide-related data (suicidal methods, combined drink of alcohol and number of previous attempts), and management-related data (disposition at ED, physician's training level, etc.). Univariated and multivariated logistic regression analyses were performed for identification of factors affecting the registration rate for the community-based post suicidal care program. RESULTS: A total of 163 suicides were included during the study period. Of these, 33 (20.2%) patients were registered in the post-suicide care program. Factors including a patient's address (OR: 14.92, 95% CI: 3.606-61.711), immediate intervention by psychiatric healthcare center (OR: 5.05, CI: 1.688-15.134), admissions in hospital (OR: 3.69, CI: 1.286-10.605), and history of previous psychiatric disease (OR: 3.52, CI: 1.216-10.201) showed significant association with registration for the program. CONCLUSION: The community-based post-suicidal care program, which is available 24 hours a day, should be operated in each district in order to increase the registration rate. Emergency physicians should actively consider the inpatient treatment program for suicidal patients and strongly recommend registration to the program, particularly for patients without previous history of psychiatric disease.

Background and Objectives: Human mesenchymal stem cells (MSCs) are emerging as a treatment for atopic dermatitis (AD), a chronic inflammatory skin disorder that affects a large number of people across the world. Treatment of AD using human umbilical cord blood-derived MSCs (hUCB-MSCs) has recently been studied. However, the mechanism underlying their effect needs to be studied continuously. Thus, the objective of this study was to investigate the immunomodulatory effect of epidermal growth factor (EGF) secreted by hUCB-MSCs on AD. Methods: and Results: To explore the mechanism involved in the therapeutic effect of MSCs for AD, a secretome array was performed using culture medium of hUCB-MSCs. Among the list of genes common for epithelium development and skin diseases, we focused on the function of EGF. To elucidate the effect of EGF secreted by hUCB-MSCs, EGF was downregulated in hUCB-MSCs using EGF-targeting small interfering RNA. These cells were then co-cultured with keratinocytes, Th2 cells, and mast cells. Depletion of EGF disrupted immunomodulatory effects of hUCB-MSCs on these AD-related inflammatory cells. In a Dermatophagoides farinae-induced AD mouse model, subcutaneous injection of hUCB-MSCs ameliorated gross scoring, histopathologic damage, and mast cell infiltration. It also significantly reduced levels of inflammatory cytokines including interleukin (IL)-4, tumor necrosis factor (TNF)-α, thymus and activation-regulated chemokine (TARC), and IL-22, as well as IgE levels. These therapeutic effects were significantly attenuated at all evaluation points in mice injected with EGF-depleted hUCB-MSCs. Conclusions EGF secreted by hUCB-MSCs can improve AD by regulating inflammatory responses of keratinocytes, Th2 cells, and mast cells.

Purpose: The mean platelet volume (MPV) is regarded as a marker for thrombosis, atherosclerosis, and inflammation in various vascular diseases. However, it still remains unclear whether plasma MPV is associated with cerebral white matter hyperintensities (WMH) and cerebral microvascular pathology in the elderly population. Materials and Methods: We examined whether MPV level is associated with the presence of cerebral WMH on brain magnetic resonance imaging from 870 non-stroke outpatient subjects. The subjects were divided into three groups according to the consecutive level of MPV (low T1, middle T2, and high T3 MPV tertile groups). To determine the association of MPV levels with the WMH, logistic regression and receiver operating characteristic curve analyses were conducted. Results: Subjects with higher MPV level were older and more likely to have hypertension, diabetes mellitus, and low renal function. Cerebral WMH were more prevalent in subjects with higher MPV level. After adjusting for confounding factors, moderate to severe cerebral WMH were significantly associated with high MPV tertile level. This association remained significant after adjusting for other cerebral vascular pathologies. T2 [odds ratio (OR): 1.49, 95% confidence interval (CI): 1.03–2.15] and T3 MPV tertile groups (OR: 1.51, 95%CI: 1.04–2.20) had more cerebral WMH lesions compared to T1 MPV tertile group. In addition, the subjects with higher Fazekas scores showed higher MPV level (p=0.020). Conclusion We found that high MPV level is independently associated with cerebral WMH. This result suggests that platelet activation plays a role in the development of cerebral WMH.

Background: This nationwide study aimed to investigate the blood transfusion status of elderly hip fracture patients and to examine the effect of packed red blood cell transfusion on all-cause mortality. Methods: From the Korean National Health Insurance Service-Senior cohort consisting of 588,147 participants aged over 60 years in 2002, a total of 14,744 new-onset hip fracture patients aged 65–99 years were followed up for 11 years. The adjusted hazard ratios (aHRs), risk ratios, and their 95% confidence intervals were estimated by the Cox proportional hazard model and Poisson regression model. Results: There were 10,973 patients (74.42%) in the transfusion group and 3,771 (25.58%) patients in the non-transfusion group. The mean volume of blood transfusion was 1,164.51 mL (± 865.25; median, 800 mL; interquartile range, 640–1,440). In the multivariable-adjusted Cox proportional hazard model, the transfusion group had 1.34-fold more risk of all-cause mortality than the non-transfusion group (aHR, 1.34; 95% confidence interval [CI], 1.26–1.42). In the multivariate-adjusted Poisson regression model, hip fracture patients in the transfusion group were 1.43 (adjusted risk ratio [aRR], 1.43; 95% CI, 1.09–1.87; p = 0.009) folds more likely to die within 30 days than those in the non-transfusion group. The mortality risk was highest at 90 days (aRR, 1.64; 95% CI, 1.40–1.93; p < 0.001) and slightly decreased at 180 days (aRR, 1.58;95% CI, 1.40–1.79; p < 0.001) and 1 year (aRR, 1.43; 95% CI, 1.31–1.58; p < 0.001). Conclusion In this nationwide representative cohort study, blood transfusion was performed in 75% of hip fracture patients. Even after adjusting for comorbidity and anticoagulant use, the postoperative results (hospitalization, mortality) of the transfusion group did not show significantly worse results than the non-transfusion group. Therefore, adequate patient blood management can only improve the patient's outcome after hip fracture surgery.

BACKGROUND/AIMS: Nonalcoholic steatohepatitis can develop from nonalcoholic fatty liver and progress to severe liver disease such as cirrhosis. The mechanism determining the progression from fatty liver to steatohepatitis is unknown. Iron is suspected to enhance hepatic damage associated with nonalcoholic fatty liver disease (NAFLD). The aims of this study were to evaluate the relationship of serum iron indices and hepatic iron deposition with hepatic fibrosis or inflammation, and to assess whether the increased hepatic iron deposition is an independent predictor of progression to liver injury. METHODS: The biochemical and histopathological data of thirty-nine patients with NAFLD were analyzed. Liver biopsy findings were graded according to the method described by Brunt, et al. Hepatic iron concentration was available in 29 of 39 patients. RESULTS: The mean hepatic iron concentration and hepatic iron indices were 1,349+/-1,188 microgram/g dry weight and 0.9+/-0.7 microgram/g/age. Serum ferritin and body mass indices were associated with hepatic inflammation (p=0.001, p=0.006) and fibrosis (p=0.005, p=0.013). Hepatic iron concentration and hepatic iron index were not associated with hepatic inflammation and fibrosis. Multivariate analysis did not identify serum ferritin or body mass index as an independent predictor of liver injury. CONCLUSIONS: Hepatic iron deposition shows no association with the degree of hepatic inflammation or fibrosis. Hepatic iron is not an independent predictor of hepatic injury in patients with NAFLD.

Endoscopic treatment of chronic pancreatitis by stent insertion is an accepted procedure, but various complications can be induced, including proximal migration of the stent. Many techniques are used to retrieve proximally migrated, pancreatic stents. We here report a case of a proximally migrated stent into the dorsal duct of a pancreas divisum, which was retrieved endoscopically by using a mini-snare. A 39-year-old female patient had chronic pancreatitis with divisum. A stent was inserted into the dorsal duct to relieve the chronic pain. After two months, sudden epigastric pain developed due to proximal migration of the stent. The pancreatic stent was retrieved successfully with one endoscopic attempt using a mini-snare. The epigastric pain resolved after retrieval of the stent. Our observation is that pancreatic stent migration may cause severe abdominal pain and that endoscopic retrieval is possible.
