Objective Multidector computed tomography (MDCT) is now commonly used for the evaluation of coronary artery disease. Because MDCT images include many non-cardiac organs and the patient population evaluated is highly susceptible to extracardiac diseases, this study was designed to evaluate the prevalence of extracardiac findings in the MDCT evaluation of ischemic heart disease. Methods From March 2007 to March 2008, a total of six-hundred twenty patients, who underwent 64-slice MDCT evaluations for chest pain, or dyspnea, were enrolled in this study. Cardiac and non-cardiac findings were comprehensively evaluated by a radiologist. Results Enrolled patients included 306 men (49.4%), with a mean age of 66 years. Significant coronary artery stenosis was found in 41.6%of the patients. A total of 158 extracardiac findings were observed in 110 (17.7%) patients. Commonly involved extracardiac organs were lung (36.7%), hepatobiliary system (21.5%), thyroid (19.6%), kidney (10.8%), spine (9.7%) and breast (0.6%). Of those 110 patients, 50 (45.5%) patients underwent further diagnostic investigations. Malignant disease was detected in three (2.7%) patients (lung cancer, pancreatic cancer, and thyroid cancer). Conclusions Extracardiac findings are frequently present and should be a concern in the MDCT evaluation of chest pain syndrome.

Catastrophic antiphospholipid syndrome (APS) is defined as a rare, life-threatening autoimmune disorder leading to multiorgan failure. Probable APS, with clinical manifestations similar to APS without antiphospholipid antibodies, was suggested to be seronegative catastrophic APS. The triggering factors of catastrophic APS are various, including infection, trauma, malignancy, and surgery. In approximately 40% of patients, catastrophic APS develops from an unknown cause. We report a case of seronegative catastrophic APS due to an unknown origin. A 20-year-old man presented with cough, abdominal pain, skin lesions, tunnel vision, and watery diarrhea without fever. His symptoms and laboratory test suggested disseminated intravascular coagulation. Considering seronegative catastrophic APS, we treated with intravenous steroid and intravenous immunoglobulin, but the effects were limited. After weekly treatment with rituximab, an immune-modulating agent, his laboratory findings including thrombocytopenia and coagulation tests, returned to normal. We conclude that rituximab can be an effective treatment for seronegative catastrophic APS.

Samter's triad is a well known syndrome and is characterized by a triad of asthma, aspirin or NSAID sensitivity and chronic sinusitis with nasal polyp. Chronic sinusitis with Samter's triad is difficult to treat completely and has poor prognosis. Tramadol is a non-opioid analgesic that rarely shows respiratory suppression and is known to be relatively safe because it does not inhibit prostaglandin synthesis. For that reason, patients with asthma may avoid drug-induced exacerbations of the disease by substituting Tramadol for NSAIDs. We experienced a case of asthma attack in a patient with Samter's triad after Tramadol injection.

BACKGROUND: Although patients with end-stage renal disease (ESRD) experience excess mortality compared with the general population, the standardized mortality ratio (SMR) for Korean patients on dialysis has not yet been investigated. In this study, we evaluated the SMR among all Korean ESRD patients on maintenance ialysis in 2009 and 2010, and compared it according to age categories, sex, and dialysis modality. METHODS: We used data from all patients on maintenance dialysis between January 1, 2009 and December 31, 2010 in Korea using the database of the Korean Health Insurance Review and Assessment Service, and the SMR was determined by calculating of the ratio between the number of actual deaths and expected deaths. RESULTS: A total of 45,568 patients in 2009 and 48,170 patients in 2010 were included in the analysis. The overall age- and sex-adjusted SMR was 10.3 [95% confidence interval (CI), 10.0-10.6] in 2009 and 10.9 (95% CI, 10.7-11.2) in 2010. The SMR for females was much higher than for males. The SMR gradually decreased with increasing age groups. The overall SMR for maintenance hemodialysis patients was lower than that of peritoneal dialysis patients. CONCLUSION: The SMR among Korean ESRD patients is likely to be higher than in other countries. Further evaluation is needed to attempt to improve the outcomes.

We analyzed the manner and cause of death in 1,193 forensic autopsies from the Jungbu province (central part of South Korea) conducted by the National Forensic Service Daejeon Institute in 2022. Analysis of the manner of deaths revealed that 43.1% (514/1,193 cases) were natural deaths; 42.8% (511/1,193 cases) were unnatural deaths; and 14.1% (168/1,193 cases) were unknown. Among the unnatural deaths, the major manner of death was 44.6% (228/511 cases) by accidents, 34.1% (174/511 cases) by suicide, 13.5% (69/511 cases) undetermined, and 7.8% (40/511 cases) by homicide. Among the unnatural deaths, the major causes of death was 38.4% (196/511 cases) by trauma, 20.4% (104/511 cases) by poisoning, and 17.6% (90/511 cases) by asphyxia. Falling was the major cause of death by trauma (58.7%, 115/196 cases), and strangulation was the major cause of death by asphyxia (75.6%, 68/90 cases). Among the natural deaths, heart disease was the major cause (46.7%, 240/514 cases), followed by endocrine, nutritional and metabolic diseases (14.0%, 72/514 cases). A time-series statistical analysis and comparison of the manner and cause of deaths in this province may facilitate more advanced interpretations relating to both public safety and healthcare in the future.

BACKGROUND/AIMS: Although multiple myeloma (MM) is typically a disease of the elderly, a certain subset of extremely young patients exists. It is necessary to establish clinicopathological characteristics for this population. METHODS: We reviewed the medical records of MM patients whose age was 40 years or younger at diagnosis. RESULTS: A total of 32 patients were analyzed (male to female ratio 19:13, median age 37 years). According to International Staging System, 29%, 48%, and 16% were in stage I, II, and III, respectively. Light chain myeloma accounted for 30%. Clinically significant anemia, hypercalcemia, azotemia, and hypoalbuminemia were present in 29%, 28%, 13%, and 28%, respectively. Three or more lytic bone lesions were detected in 45% of the patients, whereas 13% had no lytic bone lesions. Regarding treatment, 79% of patients received autologous hematopoietic stem cell transplantation. After a median follow-up duration of 64 months, the 1-, 3-, and 5-year overall survival (OS) rates were 84%, 62%, and 54%, respectively. The median OS was 61 months for the entire cohort. CONCLUSIONS: In our study, MM patients aged 40 years or younger at diagnosis showed no superior survival compared to those of the moderately elderly patients based on historical data.

The recent novel coronavirus disease 2019 (COVID-19) pandemic has led to unprecedented changes in behavior. We evaluated the current status of precautionary behavior and physical activity in chronic kidney disease (CKD) patients during the COVID-19 pandemic. Methods: A population of CKD patients (n = 306) registered in the Study on Kidney Disease and Environmental Chemicals (SKETCH, Clinical Trial No. NCT04679168) cohort recruited from June 2020 to October 2020 was included in the study. We conducted a questionnaire survey related to risk perception of COVID-19, precautionary behavior, and physical activity. Results: There were 187 patients (61.1%) with estimated glomerular filtration rate of <45 mL/min/1.73 m2 . This population showed a higher degree of risk perception for COVID-19 than the general population. Age was the most significant determinant of risk perception among CKD patients. During the pandemic, social distancing and hygiene-related behavior were significantly increased (p < 0.001). The frequency of exercise was decreased only in those who took regular exercise, without diabetes, or with a lower Charlson comorbidity index (CCI) (p < 0.001), with no change among the other groups. Socioeconomic status and comorbidities significantly affected behavioral characteristics regardless of the category. Education and income were significantly associated with precautionary behaviors such as staying at home and hand sanitizer use. Patients with higher CCI status significantly increased frequency of exercise (adjusted odds ratio, 2.10; 95% confidence interval, 1.01–4.38). Conclusion: CKD patients showed higher risk perception with active precautionary behavioral changes than the general population. Healthcare providers should be aware of the characteristics to comprise precautionary behavior without reducing physical activity.
