Background and Objectives: Although the shortage of donor is a common problem worldwide, a significant portion of unutilized hearts are classified as marginal donor (MD) hearts. However, research on the correlation between the MD and the prognosis of heart transplantation (HTx) is lacking. This study was conducted to investigate the clinical impact of MD in HTx. Methods: Consecutive 73 HTxs during 2014 and 2021 in a tertiary hospital were analyzed.MD was defined as follows; a donor age >55 years, left ventricular ejection fraction <50%, cold ischemic time >240 minutes, or significant cardiac structural problems. Preoperative characteristics and postoperative hemodynamic data, primary graft dysfunction (PGD), and the survival rate were analyzed. Risk stratification by Index for Mortality Prediction after Cardiac Transplantation (IMPACT) score was performed to examine the outcomes according to the recipient state. Each group was sub-divided into 2 risk groups according to the IMPACT score (low <10 vs. high ≥10). Results: A total of 32 (43.8%) patients received an organ from MDs. Extracorporeal membrane oxygenation was more frequent in the non-MD group (34.4% vs. 70.7, p=0.007) There was no significant difference in PGD, 30-day mortality and long-term survival between groups. In the subgroup analysis, early outcomes did not differ between low- and high-risk groups. However, the long-term survival was better in the low-risk group (p=0.01). Conclusions The outcomes of MD group were not significantly different from non-MD group. Particularly, in low-risk recipient, the MD group showed excellent early and longterm outcomes. These results suggest the usability of selected MD hearts without increasing adverse events.

PURPOSE: Over the last 30 years, Serratia marcescens (S. marcescens) has emerged as an important pathogen, and a common cause of nosocomial infections. The aim of this study was to identify risk factors associated with mortality in patients with S. marcescens bacteremia. MATERIALS AND METHODS: We performed a retrospective cohort study of 98 patients who had one or more blood cultures positive for S. marcescens between January 2006 and December 2012 in a tertiary care hospital in Seoul, South Korea. Multiple risk factors were compared with association with 28-day all-cause mortality. RESULTS: The 28-day mortality was 22.4% (22/98 episodes). In a univariate analysis, the onset of bacteremia during the intensive care unit stay (p=0.020), serum albumin level (p=0.011), serum C-reactive protein level (p=0.041), presence of indwelling urinary catheter (p=0.023), and Sequential Oran Failure Assessment (SOFA) score at the onset of bacteremia (p<0.001) were significantly different between patients in the fatal and non-fatal groups. In a multivariate analysis, lower serum albumin level and an elevated SOFA score were independently associated with 28-day mortality [adjusted odds ratio (OR) 0.206, 95% confidential interval (CI) 0.044-0.960, p=0.040, and adjusted OR 1.474, 95% CI 1.200-1.810, p<0.001, respectively]. CONCLUSION: Lower serum albumin level and an elevated SOFA score were significantly associated with adverse outcomes in patients with S. marcescens bacteremia.

Erythrodermic psoriasis (EP) is a very severe variant of psoriasis whose management poses a challenge to physicians, as currently available therapies often provide unsatisfactory results. Many biologics have been used to treat chronic plaque psoriasis, the most common form of psoriasis; however, their effectiveness for EP is poorly understood. A recently developed biologic, golimumab, has been extensively studied for the treatment of moderate-to-severe active rheumatoid arthritis, psoriatic arthritis, active ankylosing spondylitis, and chronic plaque psoriasis. However, no clinical trials have been performed for EP. Here, we report the case of a 32-year-old man who presented with severe psoriasis that previously failed to respond satisfactorily to methotrexate, cyclosporine, retinoid, narrow-band ultraviolet B phototherapy, and topical agents (i.e., steroids and calcipotriol). Skin lesions worsened progressively and developed into erythroderma. Psoriatic arthritis was also detected. Conventional therapies lacked efficacy. Therefore, we administered golimumab 50 mg. The skin lesions improved significantly according to the Psoriasis Area and Severity Index score after the first administration; lesions improved further throughout the treatment course. Although additional studies are required to fully evaluate the efficacy and safety of golimumab, this agent may be an alternative treatment strategy for some patients with recalcitrant EP.

BACKGROUND: There are limited literatures regarding the clinical characteristics of the specific dermatoses of pregnancy, and their terminology has been confusing and misleading. A simplified classification is proposed with the new terminology 'atopic eruption of pregnancy', comprising several disease entities such as eczema of pregnancy, prurigo of pregnancy, and pruritic folliculitis of pregnancy. OBJECTIVE: A clinical study was performed to determine the exact nature of atopic eruption of pregnancy in Korea. METHODS: We retrospectively reviewed the medical records of 75 patients who were diagnosed and reclassified as atopic eruption of pregnancy at Pusan National University Hospital. RESULTS: Among 121 patients with the specific dermatoses of pregnancy, 75 (62%) were diagnosed with atopic eruption of pregnancy. The most affected sites were the flexural surfaces of the neck and extremities, followed by the abdomen and back. The mean gestational age was 18.5 weeks. In 92% of cases, atopic eruption of pregnancy started during the 1st and 2nd trimesters of pregnancy. Major fetal problems were not seen. Atopic disease was observed in 26 (34.7%) patients. Total serum IgE levels were elevated in 10 (50%) patients among the 20 patients who were tested for IgE levels. Forty-four (58.5%) patients improved after delivery, and atopic eruption of pregnancy recurred after delivery in 6 (8%) patients. CONCLUSION: The characteristics of AEP in Korea were mostly similar to those of AEP in Western countries. However, AEP in Korea seems to show a poor prognosis and be refractory to treatment compared to that of Western countries.

OBJECTIVES: Rhinomanometry is a widely accepted method for objective assessment of nasal patency. However, few studies have reported the values of otherwise healthy population for nasal resistance in East Asians. The purpose of this study was to measure normal total nasal resistance (TNR) values in a large sample of Korean adults and to reveal parameters contributing to TNR values. METHODS: Subjects were enrolled from a cohort of the Korean Genome and Epidemiology Study. They were evaluated by anthropometry, questionnaire, and active anterior rhinomanometry at transnasal pressures of 100 and 150 Pascal (Pa). RESULTS: The study sample consisted of 2,538 healthy subjects (1,298 women and 1,240 men) aged 20 to 80 years. Normal reference TNR values were 0.19+/-0.08 Pa/cm3/second at 100 Pa and 0.22+/-0.09 Pa/cm3/second at 150 Pa. The TNR of women was significantly higher than that of men (P<0.0001). TNR decreased with increasing age in both genders (P<0.05). In women, lower body weight was related to increasing TNR. In men, current smokers had higher TNR than ex-smokers and never smokers. CONCLUSION: The results of the present study provide information regarding the values of otherwise healthy population of TNR and parameters associated with TNR in Korean adults.

Invasive aspergillosis can be occured in immune-compromised patients with hematopoietic stem cell transplantation, solid organ transplantation and prolonged neutropenia. The major area of invasive aspergillosis involves the sinopulmonary tract but can occur around the joint areas rarely. A 72-year-old man, who had received a liver transplant 6 years earlier, presented with a mass lesion around the right knee joint that developed 3 year earlier. Knee MRI revealed a multicystic subcutaneous mass around the knee joint. An excision was performed, and many fungal hyphae that were morphologically most consistent with Aspergillus spp. were observed in tissue. After amphotericin B therapy for 2 weeks, the patient did not show any evidence of a recurrence of invasive aspergillosis for 15 months. As Aspergillus spp. can cause a range of infections in solid organ transplants, invasive aspergillosis must be considered in patients with a recurrent cystic mass lesion.

Clinical presentations associated with acute human immunodeficiency virus (HIV) infection are various and nonspecific. Neurologic manifestations may accompany acute HIV infection. Aseptic meningitis has been described in several reports; however, acute encephalitis during acute HIV infection is rare. Some studies have suggested that antiretroviral therapy for treatment of symptomatic acute HIV infection could be beneficial, especially in severe cases. Encephalitis is life-threatening; therefore, early diagnosis and antiretroviral therapy may be needed. We report on a case of encephalitis associated with acute HIV infection. The patient received early antiretroviral therapy and recovered from encephalitis without neurological sequelae.

OBJECTIVE: To examine the reliability of upper extremity proprioceptive assessment test using virtual environment technique (VET) in patients with stroke with test-retest paradigm and define criterion for normal value by comparing with unimpaired control group. METHOD: Thirty stroke patients and 30 control groups were recruited. The VET apparatus is consisted of virtual reality upper extremity tester (VRUPT), encoder, and head-mounted display (HMD). VET-based test is composed of two tasks. Angle assessment task is required matching of imposed joint positions without visual feedback for checking angle error. Reaching assessment task is required matching of imposed cylinder with visual feedback for checking time, number of click, total interaction error. RESULTS: In the test-retest analysis, correlation coefficients ranged from 0.73 to 0.99 (p<0.01). Significant differences consistently found between affected upper extremity joint of stroke group and corresponding upper extremity joint of control group for the major variables (p<0.05). The cut off value in shoulder, elbow, wrist joints were calculated as 8.24degrees, 8.41degrees, 10.31degrees and the frequency of proprioceptive abnormalities based on these cut off value of angle error in shoulder, elbow, wrist joints showed 60%, 67%, 83% respectively, in our stroke group. CONCLUSION: This VET-based proprioceptive assessment test shows promise in assessing proprioception in patients with stroke more objectively and quantitatively.
