PURPOSE: Procalcitonin (PCT) is a current, frequently used marker for severe bacterial infection. The aim of this study was to assess the ability of PCT levels to differentiate bacteremic from nonbacteremic patients with fever. We assessed whether PCT level could be used to accurately rule out a diagnosis of bacteremia. MATERIALS AND METHODS: Serum samples and blood culture were obtained from patients with fever between August 2008 and April 2009. PCT was analyzed using a VIDAS(R) B.R.A.H.M.S PCT assay. We reviewed the final diagnosis and patient histories, including clinical presentation and antibiotic treatment. RESULTS: A total of 300 patients with fevers were enrolled in this study: 58 with bacteremia (positive blood culture) (group I); 137 with local infection (group II); 90 with other diseases (group III); and 15 with fevers of unknown origin (group IV). PCT levels were significantly higher in patients with bacteremia than in those with non-bacteremia (11.9 +/- 25.1 and 2.5 +/- 14.7 ng/mL, respectively, p < 0.001). The sensitivity and specificity were 74.2% and 70.1%, respectively, at a cut-off value of 0.5 ng/mL. A serum PCT level of < 0.4 ng/mL accurately rules out diagnosis of bacteremia. CONCLUSION: In febrile patients, elevated PCT may help predict bacteremia; furthermore, low PCT levels were helpful for ruling out bacteremia as a diagnosis. Therefore, PCT assessment could help physicians limit the number of prescriptions for antibiotics.

Hemorrhagic fever with renal syndrome (HFRS) is an acute viral disease characterized by fever, hemorrhage, and renal failure. Among the various hemorrhagic complications of HFRS, the spontaneous rupture of an arteriovenous malformation of the testicular vessels with a retroperitoneal hematoma is a rare finding. Here, we report a case of HFRS complicated by a massive retroperitoneal hematoma that was treated with transcatheter arterial embolization.

3.Report of a child with neonatal-onset multisystem inflammatory disease and review of the literature.
Chinese Journal of Pediatrics 2014;52(12):932-936
OBJECTIVENeonatal-onset multisystem inflammatory disease (NOMID) is not widely recognized in China. This study aimed to investigate the diagnosis and treatment of NOMID.
METHODTo analyze the clinical characteristics and laboratory results including skin biopsy, gene analysis and serum interleukin 1β of a boy admitted to Peking University First Hospital in November of 2013. Reports on NOMID were searched and the clinical and laboratory characteristics of reported cases were summarized.
RESULTThe patient was a 1-year-old boy. He had urticaria since 2 days after birth, and presented with episodes of fever, aseptic meningitis, symptoms of joints, short statue, hearing loss, abnormal fundus findings, and leucocytosis, high level of c-reactive protein (CRP) and abnormal findings of head MRI including ventriculomegaly and white matter dysplasia. Urticaria was confirmed by skin biopsy. Gene analysis showed T1702T/A in exon 4 of NLRP3 gene, which causes Phe568lle. Serum interleukin 1β increased dramatically. The boy was diagnosed as NOMID. He did not respond to antibiotic therapy and anti-allergy therapy. Corticosteroid therapy induced normalization of body temperature, and alleviation of rash, but not improvement in cerebrospinal fluid cell numbers. After searching reports of NOMID at PubMed, and Chinese literature published before November 2013, we summarized cases from 8 reports and reviewed 148 cases. The results showed that fever, urticaria, meningitis and arthropathy are the most common manifestations of NOMID, only 57% (69/122) of patients had mutation of NLRP3.
CONCLUSIONThis is a rare report of NOMID in children in China. Fever, urticaria, aseptic meningitis and persistently high level of CRP are characteristics of NOMID. Gene analysis and serum interleukin-1β detection can aid in diagnosis.

BACKGROUND/AIMS: Infectious mononucleosis (IM) is the clinical presentation of primary infection with Epstein-Barr virus. Although the literature contains a massive amount of information on IM, most of this is related specifically to only children or adults separately. In order to distinguish any differences between preschool children and youth patients, we retrospectively analyzed their demographic and clinical features. METHODS: Records of patients hospitalized from December 2001 to September 2011 with a diagnosis of IM were retrieved from Peking University First Hospital, which is a tertiary teaching hospital in Beijing. The demographic data and clinical characteristics were collected. RESULTS: IM was diagnosed in 287 patients during this 10-year period, with incidence peaks among preschool children (< or =7 years old, 130/287, 45.3%) and youth patients (>15 and <24 years old, 101/287, 35.2%). Although the complaints at admission did not differ between these two patient groups, the incidence of clinical signs (tonsillopharyngitis, lymphadenopathy, hepatomegaly, and edema of the eyelids) was much higher in preschool children. The incidence of liver lesion and percentage of atypical lymphocytes were significantly higher in the youth group (P<0.001), and the average hospital stay was longer in this group. Pneumonia was the most common complication, and there was no case of mortality. CONCLUSIONS: The incidence of IM peaks among preschool children and youth patients in Beijing, China. The levels of liver enzymes and atypical lymphocytes increase with age.

Early and accurate differentiation between infectious and non-infectious fever is vitally important in the intensive care unit (ICU). In the present study, patients admitted to the medical ICU were screened daily from August 2008 to February 2009. Within 24 hr after the development of fever (>38.3degrees C), serum was collected for the measurement of the procalcitonin (PCT) and high mobility group B 1 levels. Simplified Acute Physiology Score (SAPS) II and Acute Physiology And Chronic Health Evaluation (APACHE) III scores were also analyzed. Sixty-three patients developed fever among 448 consecutive patients (14.1%). Fever was caused by either infectious (84.1%) or non-infectious processes (15.9%). Patients with fever due to infectious causes showed higher values of serum PCT (7.8+/-10.2 vs 0.5+/-0.2 ng/mL, P=0.026), SAPS II (12.0+/-3.8 vs 7.6+/-2.7, P=0.006), and APACHE III (48+/-20 vs 28.7+/-13.3, P=0.039) than those with non-infectious fever. In receiver operating characteristic curve analysis, the area under the curve was 0.726 (95% CI; 0.587-0.865) for PCT, 0.759 (95% CI; 0.597-0.922) for SAPS II, and 0.715 (95% CI; 0.550-0.880) for APACHE III. Serum PCT, SAPS II, and APACHE III are useful in the differentiation between infectious and non-infectious fever in the ICU.

Scurvy is very rare disease in industrialized societies. Nevertheless, it still exists in higher risk groups including economically disadvantaged populations with poor nutrition, such as the elderly and chronic alcoholics. The incidence of scurvy in the pediatric population is very low. This study reports a case of scurvy in a 5-year-old girl with cerebral palsy and developmental delay based on MRI findings.

OBJECTIVETo determine the incidence, course, potential risk factors, and outcomes of noninfectious fever developed in patients after aortic surgery.
METHODSpatients who received operation for aortic aneurysm or dissection in our center from January 2006 to January 2008 were reviewed. Patients who met one of the following criteria were excluded: having a known source of infection during hospitalization; having a preoperative oral temperature greater than or equal to 38.0 degrees C; undertaking emergency surgery; having incomplete data. Univariate analysis was performed in patients with noninfectious postoperative fever and those without, with respect to demographics, intraoperative data, etc. Risk factors for postoperative fever were considered for the multivariate logistic regression model if they had a P value less than 0.10 in the univariate analysis.
RESULTSTotally 463 patients undergoing aortic surgery were enrolled for full review. Among them, 345 (74.5%) patients had noninfectious postoperative fever, the other 118 (25.5%) patients didn't develop postoperative fever. Univariate analysis demonstrated that several risk factors were associated with the development of noninfectious postoperative fever, including weight, surgical procedure, minimum intraoperative bladder temperature, temperature upon intensive care unit (ICU) admission, discharge, and during ICU stay, as well as blood transfusion. In a further multivariate analysis, surgical site of thoracic and thoracoabdominal aorta (odds ratio: 4.861; 95% confidence interval: 3.029-5.801; P=0.004), lower minimum intraoperative bladder temperature (odds ratio: 1.117; 95% confidence interval: 1.01-1.24; P=0.04), and higher temperature on admission to the ICU (odds ratio: 2.57; 95% confidence interval: 1.28-5.18; P=0.008) were found to be significant predictors for noninfectious postoperative fever. No difference was found between the febrile and afebrile patients with regard to postoperative hospitalization duration (P=0.558) or total medical costs (P=0.896).
CONCLUSIONNoninfectious postoperative fever following aortic surgery is very common and closely related with perioperative interventions.

Familial Mediterranean fever (FMF) is an autosomal recessive disease characterized by recurrent episodes of fever accompanied by peritonitis, pleuritis, arthritis, or erysipelas-like erythema. It is known to occur mainly among Mediterranean and Middle Eastern populations such as non-Ashkenazi Jews, Arabs, Turks, and Armenians. FMF is not familiar to clinicians beyond this area and diagnosing FMF can be challenging. We report a 22-yr old boy who presented with fever, arthalgia and abdominal pain. He had a history of recurrent episodes of fever associated with arthalgia which would subside spontaneously or by antipyretics. Autosomal recessive periodic fever syndromes were suspected. Immunoglobulin D (IgD) level in the serum was elevated and DNA analysis showed complex mutations (p.Glu148Gln, p.Pro369Ser, p.Arg408Gln) in the MEFV gene. 3D angio computed tomography showed total thrombosis of splenic vein with partial thrombosis of proximal superior mesenteric vein, main portal vein and intrahepatic both portal vein. This is a case of FMF associated with multiple venous thrombosis and elevated IgD level. When thrombosis is associated with elevated IgD, FMF should be suspected. This is the first adult case reported in Korea.

OBJECTIVEKawasaki disease (KD) is an acute and self-limited systemic vasculitis syndrome of unknown origin that mainly affects small and medium-sized arteries, particularly the coronary arteries, which is followed by aneurysm formation. Increased levels of matrix metalloproteinase-1 (MMP-1) have been detected in aortic aneurysms in adults, suggesting an important role of MMP-1 in arterial wall destruction and resultant aneurysm formation. The aim of this study was to investigate the potential role of MMP-1 in the pathogenesis of coronary artery lesions in patients with KD.
METHODSForty patients with KD, including 23 patients without coronary artery lesions (CAL) and 17 patients with CAL, as well as age-matched 10 febrile and 10 healthy afebrile controls were studied. The duration of KD was divided into three phases: the acute phase, the subacute phase and the convalescent phase. Enzyme-linked immunosorbent assay was used to detect the protein levels of MMP-1 in the sera. MMP-1 mRNA expression in the circulating leucocytes was studied using reverse transcription-polymerase chain reaction.
RESULTSLevels of MMP-1 protein in serum and MMP-1 mRNA expression in the leucocytes were significantly elevated at the acute phase in the two groups of KD patients (CAL group: 14.91 +/- 3.88 ng/ml and 0.89 +/- 0.15 ng/ml; NO-CAL group: 11.27 +/- 3.28 ng/ml and 0.77 +/- 0.14, respectively), compared with febrile (7.05 +/- 1.98 ng/ml and 0.45 +/- 0.12 ng/ml, respectively) and afebrile (5.13 +/- 1.20 ng/ml and 0.29 +/- 0.12 ng/ml, respectively) controls (P < 0.01). Furthermore, MMP-1 protein and MMP-1 mRNA levels were significantly higher in KD patients with CAL than in KD patients without CAL (P < 0.05). There was a significantly positive correlation between the serum protein level of MMP-1 at the acute phase of KD and the circulating leucocytes counts (r = 0.750, P < 0.01). The MMP-1 serum protein level and mRNA expression in the leucocytes at the acute phase of the two KD groups decreased obviously from the subacute through the convalescent phases (P < 0.05 or P < 0.01).
CONCLUSIONThe expression of MMP-1 at the acute phase of KD was significantly elevated, especially in KD patients with CAL. MMP-1 might be involved in the formation of coronary artery lesions and pathogenesis of KD.
