The latency in preterm premature rupture of membranes (PPROM) can last for weeks. We describe an extremely rare case of hand prolapse with PPROM that was exposed for 23 days before delivery. The patient had spontaneous PPROM of twin A at 21.4 weeks of gestation with shoulder presentation. The right arm of the fetus eventually protruded out the vagina and the hand was exposed for extended period of time of 23 days until delivery. Daily dressing by applying collagen to dry skin and silicone to keep moisture was done to the protruding hand to prevent dehydration and desquamation of the skin...

Preterm birth is the major challenge in obstetrics affecting ~10% of pregnancies. Pan-prostaglandin synthesis inhibitors (NSAID) prevent preterm labor and prolong pregnancy but raise concerns about fetal renal and cardiovascular safety. We conducted preclinical studies examining the tocolytic effect and fetal safety of the oral prodrug candidate OBE022 and its parent OBE002, both potent and highly selective antagonist of the contractile PGF2α prostaglandin receptor (FP). Efficacy of OBE022 and OBE002, alone and in combination with other tocolytics, was assessed in human tissues and pregnant animal models for inhibition of uterine contraction and delay of parturition...

OBJECTIVE: Premature aging and short telomere lengths of fetal tissues are associated with spontaneous preterm labor (PTL) and preterm premature rupture of membranes (pPROM). Maintenance of telomere length is performed by the enzyme telomerase. Human telomerase reverse transcriptase (hTERT) is a subunit of telomerase, and its dysfunction affects telomere shortening. This study assessed whether maternal or fetal genetic variations in the hTERT gene are associated with PTL or pPROM. METHODS: A case (PTL or pPROM) control (term birth) genetic association study was conducted in 654 non-Hispanic white mothers (438 term, 162 PTL, 54 pPROM) and 502 non-Hispanic white newborns (346 term, 116 PTB, 40 pPROM)...

Background: Postpartum bilateral femoral neck fracture (BFNF) is a rare condition. We here report a case of BFNF due to excessive corticosteroid consumption, twin pregnancy, immobility, and vitamin D deficiency. Case: This is a report of a 32-yr-old woman with bilateral femoral insufficiency fracture five days after emergency cesarean section due to preterm labor, twin pregnancy, and the history of a previous cesarean section at 33 wk. Antenatal repeated courses of betamethasone injections for fetal lung maturity, daily oral use of prednisolone for the history of miscarriage, immobilization, and vitamin D deficiency were the important contributing factors in her past medical history and lab investigations...

BACKGROUND: Preterm labor (PTL)/preterm birth (PTB) impose significant burden on healthcare systems. Women with uncomplicated pregnancies at risk of PTL/PTB have not been widely investigated, and published evidence on the costs of these women and their infants in Italy is absent. We aimed to describe women with uncomplicated pregnancies and associated costs for these women and their infants. METHODS: Data on women aged 12-44 years with uncomplicated pregnancies who delivered between 1/9/2009-31/12/2014 with PTL diagnosis alone or PTL and PTB, were included from four Italian databases...

Premature birth lacks a widely accepted classification that unites features of the clinical presentation with placental pathology. To further explore associations between the clinical categories of preterm birth and placental histology, 109 infants with gestational age <34 weeks and birth weight <2000 g were selected and, based on electronic records, were classified into preterm birth categories of preterm labor, prelabor premature rupture of membranes, preeclampsia, indicated preterm birth for maternal factors (other than preeclampsia), indicated preterm birth for fetal factors, and the clinical diagnosis of abruption...

BACKROUND: Chronic inflammation has been implicated as the underlying mechanism responsible for the pathophysiology of preterm labor. Mannose-bindig lectin (MBL) plays a central role in the innate immune response and is thus an important component of the first line of defense. The aim of this study was to investigate whether serum concentrations of MBL correlated with the incidence of preterm birth and low birth weight in a cohort of women with signs of threatened preterm birth. METHODS: A cohort of 60 patients who presented with regular contractions and/or short cervix (group A) between 24 to 32 weeks of gestation and 20 healthy controls (group B) who had no pregnancy complications and delivered at term were recruited into a prospective study...

The decidua, also known as the pregnant endometrium, is a critically important reproductive tissue. Decidual cells, comprised mainly of decidualized stromal cells and immune cells, are responsible for the secretion of hormonal and inflammatory factors which are critical for successful blastocyst implantation, placental development and play a role in the initiation of labor at term and preterm. Many pregnancy complications can arise from perturbations of a fine balance of different cell populations comprising decidua...

Preterm birth is the primary cause of neonatal deaths and morbidities. Pathological processes causally linked to preterm birth are inflammation and infection. Pellino-1 (Peli1) has previously been found to regulate the inflammatory response in non-gestational tissues in response to toll-like receptor (TLR) ligands and pro-inflammatory cytokines. The aims of this study were to determine the effect of labor on Peli1 expression in myometrium and fetal membranes, and the effect of Peli1 silencing by siRNA (siPELI1) on the production of pro-inflammatory and pro-labor mediators...

PROBLEM: It is not known whether 17-alpha-hydroxyprogesterone caproate (17OHP-C) is effective for preventing preterm delivery with an episode of preterm labor (PTL) with or without intra-amniotic inflammation/infection. METHODS OF STUDY: This was a retrospective cohort study. One hundred and seven PTL patients were selected and divided into a 17OHP-C group (use of 17OHP-C: n = 53) and a no-treatment group (no use of 17OHP-C: n = 54). Moreover, the patients were divided into three subgroups (subgroup A: without intra-amniotic inflammation, B: with mild intra-amniotic inflammation, and C: with severe intra-amniotic inflammation) according to their level of amniotic interleukin (IL)-8, and perinatal prognosis was analyzed...

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)...

BACKGROUND: To date, no intervention has proved effective in reducing the spontaneous preterm birth rate in singleton pregnancies following an episode of threatened preterm labor and short cervix remaining. OBJECTIVE: This study was designed to ascertain whether cervical pessaries could be useful in preventing spontaneous preterm birth in women with singleton pregnancies and a short cervix after a threatened preterm labor episode. STUDY DESIGN: This open randomized controlled trial was conducted in 357 pregnant women (between 240 and 336 weeks) who had not delivered 48h after a threatened preterm labor episode and had a short cervix remaining (≤25 mm at 240 -296 weeks; ≤15mm at 300 -336 weeks)...

The time of birth is a critical determinant of perinatal and long-term outcomes. Preterm birth is still the first cause of infant mortality and morbidity; unfortunately, rates of preterm birth remain high in both high- and low-resource countries, ranging from 5% to 18%. Preterm parturition is a syndrome, which can be induced by various factors such as infection, cervical pathology, uterine overdistension, progesterone deficiency, vascular alterations (utero-placental ischemia, decidual hemorrhage), maternal and fetal stress, allograft reaction, allergic phenomena, and probably other several unknown factors...

Healthy pregnancy is the most successful form of graft tolerance, whereas preterm labor (PTL) may represent a breakdown in maternal-fetal tolerance. Although maternal immune responses have been implicated in pregnancy complications, fetal immune responses against maternal antigens are often not considered. To examine the fetal immune system in the relevant clinical setting, we analyzed maternal and cord blood in patients with PTL and healthy term controls. We report here that the cord blood of preterm infants has higher amounts of inflammatory cytokines and a greater activation of dendritic cells...
