Listeriosis is caused by Listeria monocytogenes, a gram-positive bacillus common in the environment and acquired by humans primarily through consumption of contaminated food. Infection causes a spectrum of illness, ranging from febrile gastroenteritis to invasive disease, including sepsis and meningoencephalitis. Invasive listeriosis occurs predominantly in older adults and persons with impaired immune systems. Listeriosis in pregnant women is typically a mild "flu-like" illness, but can result in fetal loss, premature labor, or neonatal infection. Listeriosis is treated with antibiotics. On September 2, 2011, the Colorado Department of Public Health and Environment (CDPHE) notified CDC of seven cases of listeriosis reported since August 28. On average, Colorado reports two cases of listeriosis annually in August. By September 6, all seven Colorado patients interviewed with the Listeria Initiative* questionnaire reported eating cantaloupe in the month before illness began, and three reported eating cantaloupe marketed as "Rocky Ford."

BACKGROUND Capnocytophaga ochracea is a gram-negative anaerobic organism commonly found in human oral flora. It is characteristically sensitive to beta-lactams and resistant to aminoglycosides. CASE REPORT A 23-year-old woman presented with lower abdominal pain and was admitted for premature labor at 24-weeks of gestation. At presentation, the cervix was closed and the membrane was intact; however, contractions continued, the membrane subsequently ruptured before receiving any steroids or magnesium, and the mother gave birth to a 540-gram female baby. At birth, Apgar scores were 1 at 5 minutes, 1 at 10 minutes, and 2 at 15 minutes. On the fifth day of life, the blood culture grew Capnocytophaga species. Consequently, Cefotaxime was started and ampicillin continued for a total of 14 days; however, on the 6th day, the head ultrasound showed grade 4 intraventricular hemorrhage and a Do Not Resuscitate (DNR) order was placed in the chart. The patient's health continued to deteriorate, having multiple episodes of bradycardia and desaturation until cardiac arrest on the 17th day. CONCLUSIONS Capnocytophaga ochracea was isolated from the blood culture of a preterm neonate. It was thought to be the cause of the premature labor and subsequent neonatal septicemia. This case report suggests that the prevalence of Capnocytophaga infections is most likely underestimated and that additional premature labors and abortions could have been caused by Capnocytophaga infections that were never detected. Hence, more studies are needed to investigate the route of transmission.

Actinomycosis is a rare infection in patients younger than 10years of age. It mainly affects the cervicofacial region, but many other sites of infection have been recognized. About 70% of infections are due to either Actinomyces israelii or Actinomyces gerencseriae. Actinomyces neuii was first described in 1985 in two patients with post cataract endophthalmitis, A. neuii represents 17% of clinical Actinomyces isolates. Several reports indicated a well-known association between Actinomyces infections and Intrauterine devices (IUD). We are reporting a case of neonatal sepsis due to A. neuii as a first case reported from Saudi Arabia. It was thought to be the cause of the premature labor and neonatal sepsis. The prevalence of Actinomyces infection is likely underestimated and additional premature labors and abortions could have been caused by Actinomyces infections that were never detected. More studies are needed to confirm the association of maternal Actinomyces infections with preterm labor.

Introduction: Premature birth is a leading cause of neonatal morbidity and mortality. Since gestational age at birth is the most important predictive factor of adverse neonatal outcomes, strategies to postpone premature labor are of major importance. Studies on tocolytic drugs show that COX inhibitors such as indomethacin are superior to others in terms of efficiency in delaying birth, but results concerning neonatal outcomes associated with prenatal exposure to these drugs show controversial results. Indomethacin is also used in the postnatal age for pharmacologic treatment of patent ductus arteriosus (PDA), but no data concerning the effects of antenatal exposure on postnatal ductal patency are available.Methods: In this study, we focused primarily on the association between antenatal indomethacin (AI) and postnatal patency of ductus arteriosus while our secondary aim was to highlight any possible influence of AI exposure on adverse neonatal outcomes. We performed a retrospective analysis of 241 medical records of newborns born before 33 weeks' gestation and exposed to antenatal tocolysis. Obstetrical data and neonatal outcomes of newborns exposed to AI were compared to those of neonates exposed to other tocolytic drugs. Early ductal closure (EDC) was defined when functional echocardiography performed within 24 hours of life showed a closed duct. Occurrence of intraventricular hemorrhage (IVH), periventricular leukomalacia (PVL), respiratory distress syndrome (RDS), chronic lung disease (CLD), necrotizing enterocolitis (NEC), sepsis, and PDA were compared between the groups and the diagnosis of at least one of III-IV grade IVH, PVL, CLD, sepsis, surgical NEC, or death was defined as a severe outcome.Results: The univariate analysis showed that infants in the AI group were at a higher risk of IVH, CLD, RDS, sepsis, and PDA. The incidence of severe outcomes also appeared to be higher in this group, while no effect of AI on PDA was observed. Since we noticed that infants exposed to AI had a lower gestational age and worse clinical conditions at birth when compared to the controls, we considered this as a confounding factor. To overcome this bias, we performed a multivariate analysis that evidenced no significant role of AI on the occurrence of severe outcomes. On the other hand, a possible association was confirmed for all degrees of IVH (OR: 3.16, 95% CI : [1.41; 7.05]) and sepsis (OR: 2.81, 95% CI: [1.24; 6,28]).Conclusions: The unexpected result shown by the multivariate analysis was the association between AI exposure and EDC (OR: 2.52, 95% CI: [1.02; 6.21]). This result, which has never been evidenced in previous studies, has great clinical importance. It is well known that PDA is more frequent at lower gestational ages, thus reducing the incidence of PDA could lead to an improvement of overall outcomes in extremely preterm newborns.

Renal pelvicalyceal dilatation is caused by urine retention in the upper urinary tract. It is referred to as pyelectasis in medical literature. This term does not indicate the cause that leads to the dilatation of and urine retention in the renal pelvicalyceal system. Mild pelvicalyceal dilatation during pregnancy is usually considered to be physiological in nature - it can occur in up to 90% of pregnant women. Retention is more common in the right kidney, in primigravidae, in the second half of pregnancy and in multiple pregnancies. Pyelectasis during pregnancy rarely causes clinical symptoms and often does not require treatment. Nevertheless, urine retention in the renal pelvicalyceal system is conducive to the development of asymptomatic bacteriuria and may be a risk factor for recurrent urinary tract infections, pyelonephritis and acute kidney failure; it may also cause renal colic. In consequence, this condition can lead to intrauterine infection and premature labor in the pregnant woman and to prematurity, anemia, congenital pneumonia or sepsis in the child. In a study conducted at the 3 rd Department of Gynecology of the Medical University of Lublin it was concluded that unilateral pyelectasis of more than 20 cm 3 is associated with a significant increase in the risk of asymptomatic bacteriuria. This volume corresponds to grade 3 and/or 4 pelvicalyceal dilatation according to the Society for Fetal Urology/European Federation of Societies for Ultrasound in Medicine and Biology classification. The pyelectasis volume measuring method using three-dimensional ultrasound scanning included in the criteria for the assessment of asymptomatic bacteriuria was assessed as sensitive and specific. The ultrasound-based evaluation of the kidneys for the presence of pyelectasis and its grade in pregnant women has some clinical implications. It allows for identifying cases with an increased risk of asymptomatic bacteriuria, which requires treatment in pregnant women. Screening during pregnancy for pyelectasis seems to be important in preventing asymptomatic bacteriuria from progressing to symptomatic urinary tract infection.
