Wound sepsis is one of the main causes of death in patients with severe burn and trauma. The high incidence of burn wound sepsis in children is attributed to their imperfect immune system function, poor resistance against infection, and the weakened skin barrier function after burn. The key to reduce the mortality of pediatric patients with burn wound sepsis is to enhance the understanding of its etiology, epidemiology, pathogenesis, and diagnostic criteria, in order to improve its early diagnosis and treatment.

Portal vein thrombosis is an uncommon but an important cause of portal hypertension. The most common etiological factors of portal vein thrombosis are liver cirrhosis and malignancy. Albeit rare, portal vein thrombosis can also occur in the presence of local infection and inflammation such as pancreatitis or cholecystitis. A 52-year-old male was admitted because of general weakness and poor oral intake. He had an operation for colon cancer 18 months ago. However, colonic stent had to be inserted afterwards because stricture developed at anastomosis site. Computed tomography taken at admission revealed portal vein thrombosis and inflammation at colonic stent insertion site. Blood culture was positive for Escherichia coli. After antibiotic therapy, portal vein thrombosis resolved. Herein, we report a case of portal vein thrombosis with sepsis caused by inflammation at colonic stent insertion site which was successfully treated with antibiotics.

We describe a group of 3 cases of invasive meningococcal disease that occurred in a military training camp in April 2011. All three patients were hospitalized. Ultimately, two patients recovered and one died. One patient had meningitis, one patient had septicemia and meningitis, and the other had no definite septicemia or meningitis. Neisseria meningitidis serogroup W-135 was detected in the serum and cerebrospinal fluid (CSF) of all patients by real-time polymerase chain reaction. In the one case of mortality, two strains were isolated from the patient's blood and CSF. Using multilocus sequence typing analysis, these strains were identified as a novel sequence type, ST-8912. Special attention is required for the meningococcal disease in military camp because the military personnels are in high risk of contact transmission.

Cholangitis and cholecystitis are intra-abdominal infections that show poor prognosis upon progression to sepsis and multiorgan failure. Administration of antibiotics with high antimicrobial susceptibility and removal of infected bile at the initial treatment are important. After undergoing ERCP for diagnostic purposes, a 58-year-old man developed acute cholangitis and cholecystitis accompanied by rhabdomyolysis, multi-organ failure, and severe sepsis. Broad-spectrum antibiotics with bedside endoscopic nasobiliary drainage were administered, but clinical symptoms did not improve. Therefore, bedside EUS-guided transgastric gallbladder aspiration and lavage was performed, resulting in successful treatment of the patient. We report the above described case along with a discussion of relevant literature.

Thrombophlebitis of the portal venous system (PVS) with superimposed bacterial infection (septic pylephlebitis) is an extremely rare complication of Crohn's disease (CD), and therefore diagnosis of septic pylephlebitis is difficult without high clinical suspicion. A 16-year old male patient who was diagnosed with CD 3 months earlier was admitted with recurrent fever and abdominal pain. CD activity had been well controlled with conventional medical treatment during a follow-up period. Abdominal contrast-enhanced computed tomography showed massive thrombosis in the PVS without evidence of intra-abdominal infection, and blood cultures were positive for Streptococcus viridians. There was no evidence of deep vein thrombosis or pulmonary thromboembolism, and all laboratory tests for thrombophilia were normal. Based on these findings, the patient was diagnosed with septic pylephlebitis complicated with CD, and was successfully treated with intravenous antibiotic therapy combined with anticoagulation. This case suggests that early comprehensive evaluation is crucial for immediate diagnosis and proper treatment of septic pylephlebitis in patients with CD who present with fever and abdominal pain of unknown origin, even with stable disease activity and absence of other intra-abdominal infections.

Clostridial septicemia usually occurrs in patients with immunocompromised diseases such as diabetes and malignancy. Clostridial liver abscess is very rare but highly fatal. We experienced a case of Clostridial septicemia due to liver abscess in a 73-year-old man. He was presented with fever and chills. On admission, abdominal CT scan showed about 35 mm sized hypoattenuated lesion with multiple central air-bubbles. After the diagnosis of liver abscess, the patient underwent prompt empirical antimicrobial therapy and percutaneous drainage. In spite of early therapy, the patient had gone into shock and death.

Selective intestinal decontamination (SID) with norfloxacin has been widely used for the prophylaxis of spontaneous bacterial peritonitis (SBP) because of a high recurrence rate and preventive effect of SID for SBP. However, it does select resistant gut flora and may lead to SBP caused by unusual pathogens such as quinolone-resistant gram-negative bacilli or gram-positive cocci. Enterococcus hirae is known to cause infections mainly in animals, but is rarely encountered in humans. We report the first case of SBP by E. hirae in a cirrhotic patient who have previously received an oral administration of norfloxacin against SBP caused by Klebsiella pneumoniae and presented in septic shock.

OBJECTIVETo realize the difference between China and France in the clinical manifestations, diagnosis and treatment of early-onset neonatal sepsis (EONS) and to provide basis to improve the level of our hospital in diagnosing and treating this disease.

METHODData of 146 cases of EONS were retrospectively analyzed. All data were collected from our hospital and a French hospital. Bacterial spectrum, clinical manifestations, use of antibacterial drugs, occurrence of recording and screening of perinatal risk factors were compared between the two hospitals.

RESULTThe most common pathogenic bacteria in our hospital were coagulase-negative staphylococcus (69.2%) and Escherichia coli (15.4%) while in the French Hospital, group B streptococcus (33.3%) and Escherichia coli (33.3%). The most common pathogenic bacteria in gastric liquid and peripheral swabs of the French hospital were Escherichia coli (33.3%) and group B streptococcus (21.2%). Total days of antibacterial use 11.4 ± 7.2 (d), mean sorts of antibacterial drugs for single patient (3.1 ± 0.9) and proportion of patients who had antibacterial drug changes (70.2%) were greater than the French hospital 6.2 ± 2.5 (d), 2.2 ± 0.8(d), (9.9%). Both hospitals were inclined to combine 2 antibacterial drugs for the first dose (second-generation cephalosporins + semi-synthetic penicillin in our hospital vs. amoxicillin + amikacin in the French hospital). The common second and third line antibacterial drugs in our hospital are carbapenems and vancomycin vs. third-generation cephalosporins and vancomycin in the French hospital. The rates of occurrence of recording and screening perinatal risk factors (chorioamnionitis, maternal fever, prolonged rupture of membranes, screening results of vaginal swabs or urinary infection, amniotic fluid contamination, prenatal antibacterial prophylaxis, anamnesis of EONS) in our hospital was all lower than those of the French hospital. There was no significant difference in positive rate of perinatal risk factors between the two hospitals. For newborns hospitalized for immediate abnormalities after birth, the most common symptom was respiratory distress (96.5% vs. 88.2%). For those admitted after a period of time after birth, the proportion of abnormalities was different: in our hospital, the most common reasons were respiratory distress (44.4%) and lethargy (22.2%) while in the French hospital there were rise of C reactive proteins (78.2%) and fever (5.5%). The false negative rate of C reactive proteins in diagnosing EONS was not significantly different between the two hospitals.

CONCLUSIONThere was significant difference in diagnosing and treating EONS in the two hospitals. Emphasis on screening and recording perinatal risk factors, as well as strengthened surveillance on neonates in obstetric department could improve the accuracy of early diagnosis of EONS of our hospital. Positive attitude to gastric liquid and peripheral swabs culture, with drug susceptibility test may help pediatricians better select antibacterial drugs and reduce unnecessary changes and the total time of antibiotic use.
