Sepsis is the systemic response to infection manifested as hyperthermia or hypothermia, tachycardia, tachypnea, and shock. This condition represents a major life-threatening factor in all age groups, particularly in neonatal period. The present study aimed to examine the results of blood, cerebrospinal fluid (CSF), and urine culture tests in suspected neonatal sepsis cases in northwestern Iran. ⋯ In this study, coagulase-negative staphylococcus and Staphylococcus aureus represented the most common bacteria isolated from blood with 37.31% and 12.43%, respectively. Fungi (38.5%) and Klebsiella (28.20%) were the most common microorganic urine isolates. The results suggested that only a small percentage of suspected neonatal sepsis cases had positive blood and/or urine cultures (12.17%) and that coagulase-negative staphylococcus (CoNS) and S aureus were highly prevalent in positive blood cultures, whereas fungi and Klebsiella were the most common microorganisms found in positive urine cultures.

Case Reports
Multiple intracranial aneurysms and abdominal aortic occlusion in a young woman: A case report.
Multiple intracranial aneurysms occur in 10% to 30% patients with cerebral aneurysms. ⋯ The case highlights the importance of a thorough physical examination, and in rare cases, AAO or other abdominal aortic abnormalities should be considered in young nonsmoking females. Successful treatment can be achieved by aneurysm clipping and embolization.

Observational Study
Association analysis of CHRNA3 polymorphisms with schizophrenia in a Chinese Han population: A case-control study.
Schizophrenia (SCZ) is a highly heritable, chronic, severe psychiatric disorder associated with significant financial costs to families and societies. In this case-control study, we investigated the associations between seven SNPs in CHRNA3 gene and the risk of SCZ. A total of 1071 (384 cases and 687 controls) unrelated subjects were recruited for our association study. ⋯ According to our results, in genetic model analysis, rs12914385 and rs8040868 are associated with decreased risk of SCZ in female subgroup; rs3743075 is associated with decreased risk of SCZ in subgroup with age <45; while rs3743077 and rs2869546 are associated with increased risk of SCZ. Haplotype analysis suggested that the 3 variants comprised 1 block, and that the haplotype Ars938682Crs12914385Crs2869546 was significantly correlated with an increased risk of SCZ in the subgroup with age ≥45. Our data indicate potential associations between CHRNA3polymorphisms and SCZ susceptibility, and the significant variants identified in our study may be used as genetic biomarkers for SCZ susceptibility in Chinese Han population.

Gallbladder duplication is a rare congenital disorder, which could cause an increasing risk of complications during surgery. The coexistence of cholangiocarcinoma with double gallbladder is extremely rare, which might lead to an even higher possibility of misdiagnosis and postsurgery complications. ⋯ This is the first reported case with coexistence of gallbladder duplication and cholangiocarcinoma, which was diagnosed by abdominal ultrasound, CT and MRCP, as well as further confirmed in surgery and pathology. This case emphasized the importance of a thorough examination of gallbladder before surgery, especially in those cases with suspected double gallbladder, since each gallbladder could have the possibility of an independent cholangiocarcinoma.

Observational Study
Role of interleukin-21 and interleukin-21 receptor polymorphisms in the treatment of HBeAg-positive chronic hepatitis B patients with peginterferon.
The aim of this study was to evaluate the relationship between interleukin-21 (IL-21) and interleukin-21 receptor (IL-21R) polymorphisms and the response to peginterferon alfa (PEG-IFN α) therapy in HBeAg-positive chronic hepatitis B (CHB) patients. A total of 143 HBeAg-positive CHB patients treated for 48 weeks with PEG-IFN α and followed up for 24 weeks post-treatment were retrospectively evaluated. Genotypes analysis was performed for IL-21 polymorphisms rs907715, rs2221903, and IL-21R polymorphisms rs3093301 and rs2285452. ⋯ IL-21 rs907715 AG/GG genotype was independently associated with SVR (OR: 2.92, 95% CI: 0.98-8.6, P = .039; OR: 3.23, 95% CI: 1.0-10.4, P = .039). Patients with IL-21 rs907715 AG/GG genotype had higher serum IL-21 levels than those with rs907715 AA genotype (P = .021). IL-21 rs2221903 and rs907715 polymorphisms were significantly associated with the treatment response to PEG-IFN α among Chinese HBeAg-positive CHB patients.
