Tubo-ovarian abscess may develop in women with endometrioma following assisted reproductive technology (ART). The infection, though rare, is typically late in onset and may present several months after the procedure, and in pregnancy—with the risks of abortion and premature labor. It is thought that transcutaneous oocyte retrieval during ART is the route for bacterial contamination resulting in infection of the endometrioma. Pathogens reported in the literature include Escherichia coli (E. coli) and Group B streptococcus (GBS) but Staphylococcus lugdunensis (S. lugdunensis), a coagulase-negative staphylococcus (CoNS), and groin and perineal skin commensal was isolated from the endometrioma in this case. We discuss the challenges in diagnosis and treatment of this rare condition and the implications of the discovery that an organism previously dismissed as a contaminant has emerged as a causative organism in severe, deep-seated infections of soft tissues in recent literature.

Early-onset neonatal sepsis (EONS) remains the leading cause of morbidity and mortality, especially among premature infants. Conducting high-quality epidemiological monitoring is an important condition for effective tactics treatment neonatal infections and improving the quality of medical care for this category of newborn. The aim. Determination of the value of microbiological triggers in the blood in various clinical options for EONS in preterm infants. Materials and methods. Clinical and microbiological data on 50 prematurely born newborns with EONS were selected. The analysis of the frequency of detected bacteremia, the distribution of pathogenic microorganisms and the clinical characteristics of neonatal sepsis. Results. In the study, sources of infection were detected in 94 % of cases. Positive blood cultures were obtained in 17 (34 %) newborns with EONS. 61.5 % of all cases of bacteremia were caused by coagulase-negative staphylococcus (CoNS). Gram-negative pathogens were detected in 23.5 % of positive blood cultures, representatives of this group were Escherichia coli and Klebsiella pneumonia. The overall mortality rate from EONS was 30 %. Conclusions. The incidence of sepsis confirmed by a positive blood culture was 34 %. The most common cause of EONS is CoNS, low incidence of group B Streptococcus sepsis has been established. The most frequent septicopymic sources of infection were the lungs, which is expressed in the high incidence (94 %) of X-ray pneumonia in the structure of the EONS.

Objective Contamination of cerebrospinal fluid (CSF) by blood during neonatal lumbar puncture (LP) is common and poses diagnostic difficulties. Our objectives were to determine the number of traumatic LPs performed at the BC Children's Hospital over 9 years and whether there was an association between traumatic LPs and demographic variables, hospital location, or time of the procedure. Study Design This study was a retrospective review of neonatal CSF samples from May 2006 to March 2015. The data were analyzed to establish the rate of traumatic samples and whether there was an association between traumatic LPs and demographic variables (age, gender), location of procedure, positive CSF culture, and/or timing of the procedure. Results A total of 1,263 LPs were reviewed, 47.7% (n = 602) were contaminated with >400 red blood cells/high-power field. The median age of neonates whose samples were uncontaminated was 10.580 days compared with 6.535 days in the group with contaminated samples (z =  − 2.884, p = 0.004). None of the other factors studied was associated with traumatic taps. Detected organisms included Escherichia coli (n = 12), coagulase-negative Staphylococcus (n = 7), Enterococcus faecalis (n = 3), and group B Streptococcus (n = 2). Conclusion Nearly half of all CSF samples in the study period were contaminated. Traumatic samples were more common in younger neonates.

Introduction: Acute bacterial meningitis is one of the leading causes of mortality and morbidity in children. Identification of the causative organism is crucial to its management and outcome. The objective of this study was to see the usefulness of latex agglutination test in the early diagnosis of acute bacterial meningitis. Materials and Methods: A hospital based prospective cross-sectional study was conducted at Kanti Children’s Hospital during December 2004 to August 2005. Cerebrospinal fluid from 150 consecutive clinically suspected cases of acute bacterial meningitis between the age group of 2 months to 14 years were analyzed. Bacterial culture and latex agglutination test was done on cerebrospinal fluid obtained from all 150 suspected cases of acute bacterial meningitis. Latex agglutination test was done using the BD DirectigenTM Meningitis Combo test kit (Becton, Dickinson and company, USA) for Streptococcus pneumoniae, group B Streptococcus, Escherichia coli, Neisseria meningitidis group A,C and Y/ W135, and Hemophilus influenzae type b. Data was analysed by using SPSS Version 11.5. Results: Of the 150 Cerebrospinal fluid samples analysed bacterial culture identified only 4 meningitis cases giving an isolation rate of 1.3% whereas latex agglutination test identified 29 cases giving an isolation rate of 19.3% from 150 samples. Streptococcus pneumoniae, Hemophilus influenzae type b and Group B Streptococcus were the most common causative organism. Conclusion: Latex agglutination test has a better yield, higher sensitivity, provides microbiological diagnosis earlier than the traditional cerebrospinal fluid culture and is easy to perform.

Abstract Objective To evaluate trends in organisms causing early-onset neonatal sepsis (EONS). Congruent with recent reports, we hypothesized there would be an increase in EONS caused by Escherichia coli. Study Design National data on infants admitted to neonatal intensive care units from 2009 to 2014 were compared to previously reported data from 2003 to 2008. We report 430 cases of EONS from 2009 to 2014. Bivariate analyses were used to analyze the distribution of causative organisms over time and differences by gestational age. Linear regression was used to estimate trends in causative organisms. Results Since 2003, there has been a trend of increasing numbers of cases caused by E coli (P<0.01). The predominant organism was E coli in preterm infants and Group B Streptococcus in term infants. Conclusions With the majority of EONS cases now caused by E coli, our findings emphasize the importance of continued surveillance of causative organism patterns and developing approaches to reduce cases caused by E coli.

Background: Although there has been remarkable advancement in the field of assisted reproductive technology, implantation failure remains a significant issue in most infertile couples receiving these treatments. Embryo transfer is important in assisted reproductive technology and directly affects the implantation rates and pregnancy outcomes. Objective: To assess the effect of two different distance embryo transfer sites from fundal endometrial surface on the outcomes of in-vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycles. Materials and Methods: A total of 180 women who were candidate for IVF/ ICSI/ embryo transfer in Yazd Research and Clinical Center for Infertility were equally assigned to two groups based on the distance between the fundal endometrial surface and catheter tip to investigate implantation, chemical and clinical pregnancy (group A: 15 ± 5 mm and group B: 25 ± 5 mm, respectively). Results: The subjects in the group B showed significantly higher implantation rate, chemical and clinical pregnancy rate compared to the group A (p = 0.03, 0.01, 0.04, respectively). The rate of ongoing pregnancy and miscarriage indicated no significant differences between groups (p = 0.21, 0.27, respectively). Conclusion: In conclusion, our study showed that the depth of embryo replacement inside the uterine cavity at a distance of 25 ± 5 mm beneath fundal endometrial surface have better effects on the pregnancy outcomes of IVF/ICSI cycles and can be considered as an important factor to improve the success of IVF cycles.
