Prevalence of Multidrug-Resistant Organisms and Risk Factors for Carriage among Patients Transferred from Long-Term Care Facilities / 감염과화학요법

Background@#Patient transport between acute care hospitals and long-term care facilities (LTCFs) plays a significant role in microbial migration. The study aimed to estimate the prevalence and risk factors associated with the colonization of multidrug-resistant organisms (MDROs) among patients transferred from LTCFs. @*Materials and Methods@#We retrospectively reviewed medical records to examine the colonization of MDROs. All patients who were transferred from LTCFs and admitted to an acute care hospital with 800 beds in Daejeon between March 2018 and February 2019 were included in the study. We surveyed rectal cultures and nasal swabs obtained for screening vancomycinresistant Enterococcus (VRE), carbapenem-resistant Enterobacteriaceae (CRE), and methicillinresistant Staphylococcus aureus (MRSA) at the time of hospitalization. We conducted a multivariable logistic regression to assess the association between clinical variables and the carriage of MDROs. @*Results@#Four hundred and fifteen patients from 86 LTCFs were enrolled. A total of 31.1% (130/415) of participants carried MDROs; VRE colonization was detected in 17.1% (71/415) of participants, and MRSA colonization was shown in 19.5% (81/415) of participants. No CRE was isolated. Previous use of antibiotics within three months [odds ratio (OR) 2.28; (95% confidence interval (CI) 1.30 - 4.00), P = 0.004], use of antibiotics for longer than two weeks [OR 2.16; (95% CI 1.03 - 4.53), P = 0.040], and previous colonization of MDROs within one year [OR 2.01; (95% CI 1.15 - 3.54), P = 0.015] were independently associated with increased risk for carriage of MDROs. @*Conclusion@#Our study showed that a third of patients transferred from LTCFs carried VRE or MRSA, and prior antibiotic therapy was highly associated with the carriage of MDROs, which suggested more efficient management approaches for high-risk patients.

Campylobacter jejuni Bacteremia in a Liver Cirrhosis Patient and Review of Literature: A Case Study / 감염과화학요법

Campylobacter infection causes gastrointestinal symptoms such as abdominal pain or diarrhea. Occasionally, Campylobacter bacteremia affects immunocompromised patients; however, serious outcomes are known to be rare. Here, we present a case of a patient with Campylobacter bacteremia who had underlying liver cirrhosis. The patient had fever and diarrhea. These symptoms subsided after treatment with cefotaxime. Campylobacter jejuni was isolated in the blood culture after 10 days. In addition, previously reported cases of Campylobacter bacteremia in Asian countries were reviewed with respect to antimicrobial sensitivities.

Perception and Attitudes of Korean Obstetricians about Maternal Influenza Vaccination

Pregnant women are prioritized to receive influenza vaccination. However, the maternal influenza vaccination rate has been low in Korea. To identify potential barriers for the vaccination of pregnant women against influenza, a survey using a questionnaire on the perceptions and attitudes about maternal influenza vaccination was applied to Korean obstetricians between May and August of 2014. A total of 473 respondents participated in the survey. Most respondents (94.8%, 442/466) recognized that influenza vaccination was required for pregnant women. In addition, 92.8% (410/442) respondents knew that the incidence of adverse events following influenza vaccination is not different between pregnant and non-pregnant women. However, 26.5% (124/468) obstetricians strongly recommended influenza vaccination to pregnant women. The concern about adverse events following influenza vaccination was considered as a major barrier for the promotion of maternal influenza vaccination by healthcare providers. Providing professional information and education about maternal influenza vaccination will enhance the perception of obstetricians about influenza vaccination to pregnant women and will be helpful to improve maternal influenza vaccination coverage in Korea.

Hereditary protein S deficiency presenting acute pulmonary embolism / 영남의대학술지

Protein S deficiency is one of the several risk factors for thrombophilia and can cause blood clotting disorders such as deep vein thrombosis and pulmonary embolism. A 54-year-old man was admitted with the complaint of dyspnea and was diagnosed with pulmonary embolism. The patient had very low level of free protein S, total protein S antigen, and protein S activity (type I protein S deficiency). In history taking, we found that his mother, 78 year old, had a history of same disease 10 years ago, and confirmed the pronounced low level of protein S. The patient's son also had very low level of protein S, however there had not been any history of pulmonary embolism yet. This case study suggests that asymptomatic persons with a family history of protein S deficiency and pulmonary embolism should be checked regularly for early detection of the disease, as protein S deficiency can be suspected.

Spontaneous abdominal intramuscular hematoma in a non-dialysis chronic kidney disease patient under cilostazol therapy / 영남의대학술지

Spontaneous intramuscular hematoma of the abdominal wall is a rare condition characterized by acute abdominal pain. It is often misdiagnosed as a surgical condition. It used to be associated with risk factors such as coughing, pregnancy, and anticoagulant therapy. Most cases of abdominal wall hematomas were rectus sheath hematomas caused by the rupture of either the superior or inferior epigastric artery, but spontaneous internal oblique hematoma was extremely rare. In this report, we present a case of spontaneous internal oblique hematoma in a 69-year-old man with non-dialysis chronic kidney disease who was taking cilostazol. The patient complained of abrupt abdominal pain with a painful palpable lateral abdominal mass while sleeping. The abdominal computed tomography showed an 8 cm-sized mass in the patient's left internal oblique muscle. The administration of cilostazol was immediately stopped, and the intramuscular hematoma of the lateral oblique muscle disappeared with conservative management.

Pulmonary Cryptococcosis in a Patient with Ankylosing Spondylitis treated with Etanercept

Ankylosing spondylitis (AS) is a chronic inflammatory disorder, commonly characterized by inflammation of axial skeleton and development of enthesopathies. Tumor necrosis factor inhibitors (TNFi) shows good therapeutic responses in AS patients without good response to non-steroidal anti-inflammatory drugs. Although TNFi are relatively safe for AS patients, serious opportunistic infections, including tuberculosis and fungal infection, could develop. Here, according to our knowledge, we report a first Korean case of pulmonary cryptococcosis in a patient with AS treated with etanercept. A 64 year-old man with AS visited due to a newly appeared pulmonary nodule on a routine chest radiography. He had been administered etanercept for 5 months. Histologic findings of the lung nodule showed characteristic features of cryptococcosis. Etanercept was discontinued and oral fluconazole was administrated, as there was no evidence of central nervous system involvement. After 7 months of treatment, chest CT showed an improvement of the pulmonary lesion.

Mushroom Poisoning by Podostroma cornu-damae: A Case Report and Review of the Literature

Podostroma cornu-damae is a rare species of fungus belonging to the Hyocreaceae family. Its fruit body is highly toxic, as it contains trichothecene mycotoxins. Unfortunately, it highly resembles Ganoderma lucidum and Cordyceps, well-known health foods; this can lead to poisoning. We experienced such a case of a 42-year old man who received mushroom poisoning by injesting Podostroma cornu-damae. The patient was presented with severe pancytopenia and infection. The patient recovered without any complications after conservative care, antibiotics therapy, and granulocyte colony stimulating factor administration. The most common complications of podostroma cornu-damae intoxication were reported pancytopenia, infection, disseminated intravascular coagulation, acute renal failure, etc. It is important to provide enough fluid therapy, use of antibiotics to infection and granulocyte colony stimulating factor administration.
