Courtney L Maxey-Jones, Alec Palmerton, Jocelyn R Farmer, Brian T Bateman
Difficult airway management in the gravid patient is a well-described phenomenon. We present a case of emergent cesarean delivery complicated by a "cannot intubate, cannot ventilate" scenario that was later determined to be secondary to an allergic, IgE-mediated reaction to epidurally administered local anesthetic.

Anemia and micronutrient (MN) deficiencies in pregnant women are associated with adverse pregnancy outcomes. In Niger, 58.6% of pregnant women are anemic; however, MN statuses are unknown. The study objectives were to estimate the prevalence of MN deficiencies among pregnant women in Zinder, Niger and explore associated risk factors. Pregnant women living in randomly selected rural villages (n = 88) were included. Capillary and venous blood samples (n = 770) were analyzed for hemoglobin (Hb) and plasma ferritin, soluble transferrin receptor (sTfR), zinc (pZn), retinol binding protein (RBP), folate and vitamin B12...

Perforative peritonitis is the most common surgical emergency in general surgical practice. Gastrointestinal perforation is the etiology in the vast majority of the patients. However, occasionally, other rare causes may be encountered. One such cause of peritonitis is spontaneous perforation of non-gravid uterus. Uterine perforation is a potential complication of any intrauterine procedure and may be associated with injury to surrounding blood vessels or viscera such as the urinary bladder or intestine. Spontaneous uterine perforation is rare and less than 50 cases have been reported in the English literature...

The endometrium of pregnant and cyclic pigs is a source of oestrone (E1) and 17β-oestradiol (E2). However, the roles of LH, FSH and prolactin (PRL) as regulators of endometrial steroidogenesis, and the presence of 17β-hydroxysteroid dehydrogenase (17β-HSD) in the porcine endometrium, remain unknown. Therefore, in the present study we examined 17β-HSD expression and the effects of LH, FSH and PRL on E1 and E2 release in vitro in endometrial explants harvested from gravid pigs on Days 10-11 (embryo migration within the uterus), 12-13 (maternal recognition of pregnancy) and 15-16 (beginning of implantation) and compared them with results obtained in non-gravid pigs...

A new nematode Parapharyngodon hugoi n. sp. (Oxyuroidea: Pharyngodonidae) is described parasitising the large intestine of the tree frog Trachycephalus typhonius (Linnaeus) (Anura: Hylidae) from the wetlands of Pantanal, State of Mato Grosso do Sul, Brazil. The new species exhibits a unique structure of the posterior cloacal lip in males, which is supported by a rigid V-shaped structure. Parapharyngodon hylidae parasitic in hylid frogs, including T. typhonius, from Mexico, is the most similar congener to P...

All cockroach species, except one, harbor the endosymbiont Blattabacterium, transmitted from females to embryos. Adult cockroaches acquire non-Blattabacterium bacteria as part of their gut microbiota over time, but our knowledge of the possible transmission of these non-Blattabacterium bacteria from females to embryos is rudimentary. We characterized the gut microbiota of gravid viviparous Diploptera punctata females and the non-Blattabacterium microbiota of associated developing embryos, as well as the gut microbiota of non-gravid females, and the microbiota of orphan embryos (females not included), following high-throughput sequencing of the 16S rRNA gene to assess bacterial transference...

The insufficiently known nematode species Philometra margolisi Moravec, Vidal-Martínez et Aguirre-Macedo, 1995 (Philometridae) is redescribed based on light and scanning electron microscopical (SEM) examinations of specimens collected from the gonad of the type host, the red grouper Epinephelus morio (Valenciennes) (Serranidae, Perciformes), in the northern Gulf of Mexico off Florida, USA. Also, new prevalence data for females of P. margolisi were derived from 188 fish, and a subset of these (n = 38) were used to determine prevalence and intensity of male nematodes...

Takayasu arteritis is a rare, chronic vasculitis of unknown etiology characterized by inflammation of the aorta and its main branches. Although Takayasu arteritis mostly affects women of childbearing age, there is a paucity in the literature on pregnancy associated with Takayasu arteritis. Pregnant patients are at increased risk of cardiovascular complications, including hypertension and congestive heart failure, which may jeopardize both maternal and fetal outcomes. Furthermore, optimal management has not yet been established for pregnant patients with Takayasu arteritis, posing a clinical challenge...

Understanding the dispersal of Aedes (aegypti (L.) Diptera: Culicidae) after consuming a potentially infectious bloodmeal is an important part of controlling the spread of the arboviruses it transmits. Because of the impact on abundance, removal of oviposition sites is a key component of vector control. However, source reduction around a case may encourage dispersal of potentially infected vectors. We compare the effect of oviposition site availability on Ae. aegypti dispersal behavior within 30-m linear cages in three model ecosystems at the University of Arizona's Biosphere 2 research facility...

Chlamydia trachomatis serovars D-K are one of the most frequent causes of sexually transmitted infections of the female genital tract, with possible complications such as hydrosalpinx, pelvic inflammatory disease, extra-uterine gravidity or infertility. We used the murine genital tract infection model with C. muridarum for vaccination studies and found that more than 70% of the infected mice suffered from uterus dilatations and/or hydrosalpinx. Systemic consequences of the vaginal infection were apparent by splenomegaly ten to fifteen days post infection...

Intrapartum uterine rupture is a life-threating and rare complication of pregnancy which seldom occurs in the second trimester. Typically, the diagnosis is made using ultrasound; however, magnetic resonance imaging can provide certain advantages in the emergent setting. We present a unique case of a posterior uterine rupture confirmed by magnetic resonance imaging to be involving the unscarred posterior uterine wall in a 20- year- old gravid female with two previous cesarean-sections.

INTRODUCTION: Abnormal uterine bleeding (AUB) is the commonest menstrual problem during perimenopause. The International Federation of Gynaecology and Obstetrics working group on menstrual disorders has developed a classification system (PALM-COEIN) for causes of the AUB in non-gravid women. The present study was conducted with the aim to study the two components of this system in clinical practice in general and to establish a clinico-pathological correlation of AUB with context of PALM component in particular...

Erik M Blosser, Nathan D Burkett-Cadena
In the genus Culex, oviposition is often generalized as laying floating egg rafts directly on the surface of the water, as reported for arbovirus vectors Culex pipiens L. and Culex tarsalis Coquillett, both members of subgenus Culex. The current work reports on investigations of exceptions to this strategy by species of Melanoconion, a diverse and mostly tropical subgenus of Culex, with many arbovirus vectors. Wild gravid females from Vero Beach, FL, were introduced into outdoor cages with open water, partially covered water, and emergent solid structures for oviposition...

Aedes koreicus (Edwards) is an invasive mosquito species, like Aedes albopictus (Skuse) and Aedes japonicus japonicus (Theobald), that has already colonized a large part of northeastern Italy and other European countries. Despite its rapid expansion, information about adult distribution and trapping is lacking. Here, we conducted a 2-yr longitudinal survey using adult traps to investigate the spatiotemporal distribution of Ae. koreicus and evaluated the effectiveness of three trapping devices in Latin square experiments conducted in an urban site and a forested site...

Regulation of myometrial functions during pregnancy has been considered the result of the integration of endocrine and mechanical signals. Nevertheless, uterine regeneration is poorly understood, and the cellular source within the gravid uterus is largely unexplored.In this study, we isolated and quantified the myometrial stem cells (MSC) population from pregnant female Eker rat uteri, by using Stro1/CD44 surface markers. We demonstrated that prior parity significantly increased the percentage of Stro1+/CD44+ MSC because of injured tissue response...

Aedes aegypti is an important subtropical vector species and is predicted to have a limited year-round distribution in the southern United States. Collection of the species has not been officially verified in Oklahoma since 1940. Adult mosquitoes were collected in 42 sites across 7 different cities in Oklahoma using 3 different mosquito traps between May and September 2016. Between July and September 2016, 88 Ae. aegypti adults were collected at 18 different sites in 4 different cities across southern Oklahoma...

REVIEW
Katherine Smith, Bernard Gros
A well-established association exists between acute aortic dissection and pregnancy, particularly in women with Marfan syndrome. However, there is debate regarding appropriate management guidelines. In particular, there are differing opinions regarding when prophylactic aortic root repair should be recommended as well as the efficacy of beta blockers in this clinical scenario. The current study evaluated 10 years of published literature (2005-2015) in the PubMed/Medline database. Fifty articles, describing 72 cases of women who presented with aortic dissection in the antepartum or postpartum period were identified...
