Outbreak of COVID-19 is ongoing all over the world. Spine trauma is one of the most common types of trauma and will probably be encountered during the fight against COVID-19 and resumption of work and production. Patients with unstable spine fractures or continuous deterioration of neurological function require emergency surgery. The COVID-19 epidemic has brought tremendous challenges to the diagnosis and treatment of such patients. To coordinate the diagnosis and treatment of infectious disease prevention and spine trauma so as to formulate a rigorous diagnosis and treatment plan and to reduce the disability and mortality of the disease, multidisciplinary collaboration is needed. This expert consensus is formulated in order to (1) prevent and control the epidemic, (2) diagnose and treat patients with spine trauma reasonably, and (3) reduce the risk of cross-infection between patients and medical personnel during the treatment.

PURPOSE: Hospital-acquired Burkholderia cepacia (B. cepacia) infection are not commonly recorded in patients without underlying lung disease, such as cystic fibrosis and chronic granulomatous disease. However, in 2014, B. cepacia appeared more frequently in pediatric blood samples than in any other year. In order to access this situation, we analyzed the clinical characteristics of B. cepacia infections in pediatric patients at our hospital. MATERIALS AND METHODS: We conducted a retrospective study of blood isolates of B. cepacia taken at our hospital between January 2004 and December 2014. Patient clinical data were obtained by retrospective review of electronic medical records. We constructed a dendrogram for B. cepacia isolates from two children and five adult patients. RESULTS: A total of 14 pediatric patients and 69 adult patients were identified as having B. cepacia bacteremia. In 2014, higher rates of B. cepacia bacteremia were observed in children. Most of them required Intensive Care Unit (ICU) care (12/14). In eleven children, sputum cultures were examined, and five of these children had the same strain of B. cepacia that grew out from their blood samples. Antibiotics were administered based on antibiotic sensitivity results. Four children expired despite treatment. Compared to children, there were no demonstrative differences in adults, except for history of ICU care. CONCLUSION: Although there were not many pediatric cases at our hospital, awareness of colonization through hospital-acquired infection and effective therapy for infection of B. cepacia is needed, as it can cause mortality and morbidity.

Since May 20, 2015, when the first case of Middle East respiratory syndrome (MERS) in South Korea was confirmed, the cluster case in South Korea has grown to become the largest observed case following Saudi Arabia within the span of one month. Akin to what was observed in the Middle East, confirmed cases were infected through nosocomial transmission where the cluster is largely limited to patients, healthcare workers, and visitors to patients in healthcare facilities with confirmed cases. A major difference from the outbreaks in the Arabian Peninsula has been the large number of tertiary transmission cases in South Korea, which had reached forty cases by June 12. This observation may suggest that despite the lack of genetic mutation of Middle East respiratory syndrome coronavirus (MERS-CoV) in South Korea, the virus may be behaving differently from that of the Middle East. The higher infectiousness of 'super-spreaders' in South Korea also suggests that this assertion should be under further investigation. Suggestions of inadequate triage in emergency rooms, particularly at Samsung Medical Center which accounts for the most nosocomial infection with 60 cases, have been made by several organizations as the basis for this rapid spread. This, however, does not account for the fact that triage was impossible to implement, since the presence of MERS-CoV in South Korea was unknown during the index patient's stay at the healthcare facilities. This paper aims to identify the key factors in the amplified spread of MERS-CoV in South Korea. The first is the initial failure to confirm diagnosis promptly and to isolate the index case after confirmation of MERS in hospital and the lack of detail in tracking potential exposures in the community of the index case before isolation. The second is the early inadequate measures the Korea Centers for Disease Control and Prevention took in categorizing close contacts. Due to inconsistencies in defining what constitutes close contact, a number of cases were neglected from quarantine and were not subjected to investigation. Finally, confirmed or potential MERS patients were admitted for treatment and observation at medical facilities without adequate disease control measures or rooms, such as ventilated single rooms or airborne precaution rooms. Due to the rigid position that MERS-CoV cannot be transmitted via airborne means, infection control measures has so far neglected evidence that smaller droplets (aerosol) containing the virus can act similar to airborne agents, which may account for the widespread and rapid transmission in a emergency room and a patient's room in hospital. Although the South Korean government expects newly confirmed cases to abate in the coming few weeks, without stringent implementation of clearly defined guidelines to control further transmissions, the cessation of the current trend may continue for an extended period. Additionally, due to the high infection rate of super-spreaders in South Korea, efforts to screen for potential super-spreaders and a thorough investigation of those confirmed to be super-spreaders should be done to quickly identify source of infection, to potentially lower the number of secondary, tertiary transmissions and prevent possible quaternary transmissions.

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.

Infective endocarditis (IE) has been increasingly diagnosed in patients without previously detected predisposing heart disease, but its clinical features have yet to be fully determined. A recent single-center study including echocardiographic images and surgical findings investigated the incidence of undiagnosed, clinically silent valvular or congenital heart diseases and healthcare-associated infective endocarditis (HAIE). The study confirmed that a large proportion of patients with IE have no previous history of heart disease. Analysis of underlying disease in these patients showed that undetected mitral valve prolapse was the most common disease, followed by an apparently structurally normal valve. The patients who developed IE of apparently structurally normal valves had different clinical characteristics and worse outcomes. IE involving a structurally normal valve was associated with both nosocomial and non-nosocomial HAIE, whereas community-acquired IE was more frequent than HAIE. The pathophysiologic mechanism involving the development of non-HAIE or community-acquired IE due to predominantly staphylococcal infection in an apparently structurally normal valve is not yet clearly understood. Structurally normal valves are not necessarily free of regurgitation or abnormal turbulence and, given the dynamic nature and fluctuating hemodynamic effects of conditions such as poorly controlled hypertension, end-stage renal disease, and sleep apnea, further investigation is necessary to evaluate the potential role of these diseases in the development of IE. An apparently normal-looking valve is associated with IE development in patients without previously recognized predisposing heart disease, warranting repartition of at-risk groups to achieve better clinical outcomes.

OBJECTIVETo understand the risk factors of measles among babies under 8-months-old and people ≥15 years old, in Gansu province.

METHODSLaboratory-confirmed measles cases were divided into two groups among children below 8-months-old and those ≥15 year olds. Descriptive epidemiology and 1:3 case control study were conducted to find out those related risk factors as:hospital exposure, contact with measles cases, vaccination, history of measles etc. so as to determine the risk factors and appropriate control measures.

RESULTSHistories of hospital exposure, contact with measles cases and travelling to other cities were risk factors for measles among babies younger than 8-months and people ≥15 year olds. Vaccination appeared a protective factor for people ≥15 years of age. From 42 cases and 126 controls, through multivariate analysis, results showed that hospital exposure was the only significant factor ( OR = 29.23, 95%CI:2.82-302.89)for those babies younger than 8-months. Factors as hospital exposure and travelling among cities for 7-21 days before being infected, were with significant importance ( OR = 5.15, 95% CI:2.28-11.63; OR = 5.48, 95%CI:1.38-21.69)for people ≥15 years of age, according to the observation from 74 cases and 222 controls.

CONCLUSIONIn order to reduce the incidence of measles among babies under 8-month-old and people ≥15 years old, efforts on control of nosocomial infection should be strengthened, while the routine immunization coverage need to be increased for the children at higher risks, to reduce the source of infection.

OBJECTIVETo determine risk factors of invasive fungal infections (IFI) in patients admitted to non-hematological oncology department and pediatric intensive care unit (PICU), in order to improve diagnostic level of invasive fungal infections.

METHODWe retrospectively assessed 85 hospitalized pediatric patients with invasive fungal infections in Beijing Children's Hospital Affiliated to Capital Medical University from Jan.2007 to Nov.2012. All the cases were either from non-hematological oncology department or the PICU.We reviewed risk factors of invasive fungal infections.

RESULTAmong 85 patients, 42 had invasive candida infection, 20 invasive aspergillus infection, 21 cryptococcus infection, 1 Histoplasma capsulatum infection and 1 Mucor mucedo infection.In the 42 patients with invasive candida infection, 5 were young infants, 3 had combined immunodeficiency, 1 cellular immunodeficiency, 25 secondary infection due to long term use of corticosteroids and/or combined use of more than 2 kinds of antibiotics with primary disease, 5 prior intestinal tract surgery or chronic diarrheal disease, 1 reflux gastritis.In the 20 patients with invasive aspergillosis infection, 10 patients had chronic granulomatous disease, 5 long term use of corticosteroids ≥ 1 month, 3 long term use of corticosteroids and combined use of more than 2 kinds of antibiotics, 2 had no apparent host factors.In the 21 patients with cryptococcus infection, 2 patients had used corticosteroids ≥ 1 month, 2 had immunodeficiency mainly for lack of antibodies, while others had no apparent host factors. The child with Mucor mucedo infection had diabetes mellitus. And the one with Histoplasma capsulatum infection had immunodeficiency.

CONCLUSIONHigh risk factors for IFI in patients admitted to non-hematological oncology department and PICU are primary immunodeficiency disease and long term use of corticosteroids and/or long term combined use of more than 2 kinds of antibiotics. Besides, young infant is also a high risk factor for invasive candida infection. Most of the cryptococcus infections and certain aspergillosis had no obvious host factors.

OBJECTIVEThis study aimed to explore the epidemiological factors of an influenza A (H1N1) outbreak in a hospital.

METHODSGeneral data were collected via face-to-face interview and telephone survey. Total 132 individuals including medical and nursing staffs (37), in-patients (39) and patients' family members (56) who were exposed to the pediatric surgery ward during August 11 - 18, 2009, were investigated. The case group included 35 cases according to the diagnostic criteria for influenza A (H1N1). The other 97 persons were grouped as control. A case-control study was then conducted to explore the epidemic factors, and layering analysis was applied to determine the interactions among these factors.

RESULTSThe overall incidence in this study was 26.5% (35/132), which included 12 confirmed and 23 suspected cases, and there was no severe case. The first case was a child with the influenza-like symptoms before admission on August 11. The onsets of these cases were during August 7 - 17. The cases were distributed in 9 of 13 rooms, and there was no room aggregation in the cases distribution (χ(2) = 0.00, P > 0.05). Twelve of 25 oropharyngeal swabs were influenza A (H1N1) nucleic acid positive. The case-control study showed that exposure to the enema room accounted for 93.10% (27/29) in cases and 72.73% (48/66) in control; OR = 5.06, 95%CI = 1.01 - 34.23), long time exposure to ward was 71.43% (25/35) in cases and 44.33% (43/97) in control; OR = 3.14, 95%CI = 1.27 - 7.90), and short distance contact with the nurse LIU (76.46% (26/34) in cases and 50.52% (49/97) in control; OR = 3.18, 95%CI = 1.22 - 8.54) were the risk factors. However, keeping the window open (27.59% (8/29) in cases and 68.18% (45/66) in control; OR = 0.14, 95%CI = 0.05 - 0.39) and hand washing (25.71% (9/35) in cases and 76.29% (74/97) in control; OR = 0.11, 95%CI = 0.04 - 0.28) were the protective factors. The longer time exposure to ward had the higher risk (ratios of cases to control were 4:20 (0 - 1 day), 6:34 (2 - 4 days) and 25:43 (≥ 5 days); χ(2)(trend) = 5.737, P < 0.05). In contrast, hand washing with more frequencies (ratios of cases to control were 26:23 (0 - 1 time one day), 7:9 (2 - 3 times one day) and 2:65 (≥ 4 times one day); χ(2)(trend) = 37.136, P < 0.01) and the longer time window opening (ratios of cases to control were 21:21 (no), 4:13 (a few) and 4:32 (often); χ(2)(trend) = 13.830, P < 0.01) had the lower risk. Nevertheless, layering analysis excluded long time exposure to ward from the risk factors (for individuals with more frequent hand washing, 6.90% (2/29) exposed in cases, 7.14% (1/14) exposed in control, OR = 0.97, 95%CI = 0.06 - 29.51; for individuals keeping window open, 21.21% (7/33) exposed in cases, 8.33% (1/12) exposed in control, OR = 2.55, 95%CI = 0.26 - 60.87), indicating the main risk factors in this outbreak were exposure to the enema room and short distance contagion with the infected nurse.

CONCLUSIONThe influenza A (H1N1) outbreak in this hospital was induced by an inpatient infected with influenza A (H1N1) virus before admission. Infected medical staffs keeping on work and exposure to the same place, e.g.the enema room in this study might spread the influenza A (H1N1) virus, and frequent hand washing and keeping the window open are the most effective and economic methods to prevent influenza A (H1N1) infection.
