RESUMO
BACKGROUND: Scrub typhus is an acute febrile illness, which was caused by Orientia tsutsugamushi and transmitted through the bite of chiggers. The diagnosis of scrub typhus could be missed diagnosis due to the absence of the pathognomonic eschar. CASE PRESENTATION: A 76-year-old man was hospitalized with fever and kidney injury and was diagnosed of hemorrhagic fever with renal syndrome first. However, the situation of the illness deteriorated into refractory septic shock and multiple organ dysfunction rapidly,although the treatment of anti-sepsis was used in 3rd-5th day. Orientia tsutsugamushi was determined to be the causative pathogen by Next-generation sequencing of his plasma sample in 6th day. Then, the patient was treated with doxycycline and azithromycin and recovered quickly. CONCLUSIONS: Next-generation sequencing was a new diagnostic technology and could identify scrub typhus in accurately and fast without the pathognomonic eschar.

BACKGROUND: Neutrophil gelatinase-associated lipocalin (NGAL) is currently known as an acute phase protein and implicated in acute brain injury. Herein, we sought to gauge serum NGAL level in patients after acute (<24â¯h) spontaneous intracerebral hemorrhage (ICH) and to investigate its relation to neurological outcome. METHODS: Serum NGAL levels were measured in 106 patients and 106 controls. National Institutes of Health Stroke Scale (NIHSS) score, Glasgow coma scale (GCS) score, ICH score and hematoma volume were recorded for assessing hemorrhagic severity. An unfavorable outcome was defined as modified Rankin Scale >2 at 90â¯days. RESULTS: As opposed to the controls, the patients had significantly raised serum NGAL levels. Correlations were observed between NGAL levels and serum C-reactive protein levels, blood glucose levels, GCS score, NIHSS score, ICH score and ICH volume. Multivariate analysis identified serum NGAL as a predictor for unfavorable outcome at 90â¯days. It also showed high prognostic ability under receiver operating characteristic curve. CONCLUSIONS: Enhanced NGAL level is revealed after acute spontaneous ICH, in association with inflammatory degree and hemorrhagic severity, and intimately correlated with a worse prognosis.

BACKGROUND: Nosocomial infections are a major threat to patients in the intensive care unit (ICU). Limited data exist on the epidemiology of ICU-acquired infections in China. This retrospective study was carried out to determine the current status of nosocomial infection in China. METHODS: A retrospective review of nosocomial infections in the ICU of a tertiary hospital in East China between 2003 and 2007 was performed. Nosocomial infections were defined according to the definitions of Centers for Disease Control and Prevention. The overall patient nosocomial infection rate, the incidence density rate of nosocomial infections, the excess length of stay, and distribution of nosocomial infection sites were determined. Then, pathogen and antimicrobial susceptibility profiles were further investigated. RESULTS: Among 1980 patients admitted over the period of time, the overall patient nosocomial infection rate was 26.8% or 51.0 per 1000 patient days., Lower respiratory tract infections (LRTI) accounted for most of the infections (68.4%), followed by urinary tract infections (UTI, 15.9%), bloodstream (BSI, 5.9%), and gastrointestinal tract (GI, 2.5%) infections. There was no significant change in LRTI, UTI and BSI infection rates during the 5 years. However, GI rate was significantly decreased from 5.5% in 2003 to 0.4% in 2007. In addition, A. baumannii, C. albicans and S. epidermidis were the most frequent pathogens isolated in patients with LRTIs, UTIs and BSIs, respectively. The rates of isolates resistant to commonly used antibiotics ranged from 24.0% to 93.1%. CONCLUSION: There was a high and relatively stable rate of nosocomial infections in the ICU of a tertiary hospital in China through year 2003-2007, with some differences in the distribution of the infection sites, and pathogen and antibiotic susceptibility profiles from those reported from the Western countries. Guidelines for surveillance and prevention of nosocomial infections must be implemented in order to reduce the rate.
