INTRODUCTION: It can be observed that there is an increase in the methamphetamine (MA) consumption in Saxony (Federal Republic of Germany). There is so far no data available in German speaking countries about the risk of MA consumption in pregnancy or delivery. METHODS: The data from all pregnant women who were examined or delivered at the Clinic for Obstetrics and Gynaecology between 2010-2015 were retrospectively searched for MA consumption. 119 pregnancies with 113 deliveries of 115 women consuming MA could be evaluated...

BACKGROUND: Among anterior mediastinal tumors, a teratoma is known to rupture with growth, but there have been few previous reports about thymoma rupture. We here report a rare case of an invasive thymoma with intrapulmonary and intrathoracic rupture requiring emergency life-saving surgery. To our knowledge, this is the first such case in the literature. CASE PRESENTATION: A 56-year-old woman suddenly experienced right precordial pain and hemoptysis. Enhanced computed tomography revealed a large mediastinal tumor pressing against the pulmonary hilar vascularity, with extravasation of blood into the right lung...

"Childhood glaucoma" is a heterogenic group of diseases, characterized by elevated intraocular pressure (IOP) associated with optic-disc damage and other ocular comorbidities. Diagnosis requires two or more of the following: elevated IOP, optic nerve damage, enlarged cornea or Descemet's membrane ruptures, enlarged eye, high myopia and visual field defects. Childhood glaucoma is classified as primary if it occurs as an isolated ocular disease, and secondary, when the disease occurs along with other ocular anomalies or systemic diseases such as Neurofibromatosis and Sturge-Weber, or with acquired conditions such as uveitis complications, ocular trauma, cataract surgery, as well as from systemic and ocular steroid use...

Glucocorticoid use during pregnancy is known to increase the risk of preterm birth and preterm premature rupture of membranes (pPROM). Here, we investigated the mechanism of how glucocorticoids weaken the fetal membranes. The amnion mesenchymal layer was significantly thinner in pregnant women treated with prednisolone and corticosterone-injected mice compared to control groups. Matrix metalloproteinse-9 (MMP9) mRNA and its activity, COX2 mRNA levels, and PGE2 synthesis were increased whereas type 1 collagen (COL1A1) mRNA levels were decreased in the fetal membranes of corticosterone-injected mice...

INTRODUCTION: Transcatheter aortic valve implantation (TAVI) has emerged as a less invasive treatment than surgical aortic valve replacement in patients with aortic stenosis. Understanding the anatomy of aortic valve complex may help in optimal positioning of prosthetic valve and circumvent complications that can arise during its implantation. MATERIAL AND METHODS: The anatomy of aortic root was studied in 30 formalin-fixed cadavers. Aortic root and left ventricular cavity was opened to measure the diameter at the base of aortic root and sinotubular junction (STJ); distance of coronary ostia from base of aortic root and STJ; height and width of aortic valve leaflets; length and thickness of membranous septum (MS)...

A 36-year-old woman with a history of one previous caesarean section presented to the birthing suite of a regional hospital with spontaneous rupture of membranes at 39+2/40 weeks. Syntocinon was administered to initiate uterine contractions in the absence of labour, as the patient desired vaginal birth. A caesarean section was subsequently indicated and ergometrine was administered for uterine atony. The patient immediately developed atrial fibrillation (AF). AF is the most common sustained arrhythmia in the general population, but is rare in the obstetric population...

BACKGROUND: Placental insufficiency may be the cause of the high preterm birth rate in women after Fontan operation. In this study we reviewed the clinical course and pregnancy outcome of women with Fontan physiology with a focus on placental pathology. METHODS: We reviewed clinical charts and placental pathology from 7 women with Fontan physiology who had pregnancies at Mayo Clinic, Rochester, Minnesota. The review was limited to cases where placental pathologic specimens were rigorously examined...

BACKGROUND: Few studies have examined the relationship between sexually transmitted infections (STIs) and preterm birth (<37 weeks gestation) by subtype (<32 weeks, 32 - 36 weeks, spontaneous, provider-initiated). Here, we evaluate the odds of preterm (by subtype) and early term (37 and 38 weeks gestation) birth in women with an STI compared to a propensity score matched reference population. METHODS: The sample was selected from California births in 2007-2012...

Researchers have demonstrated great promise for inorganic nanowire use in analyzing cells or intracellular components. Although a stealth effect of nanowires toward cell surfaces allows preservation of the living intact cells when analyzing cells, as a completely opposite approach, the applicability to analyze intracellular components through disrupting cells is also central to understanding cellular information. However, the reported lysis strategy is insufficient for microbial cell lysis due to the cell robustness and wrong approach taken so far ( i...

We used elastic incoherent neutron scattering (EINS) to find out if structural changes accompanying local hydrogen bond rupture are also reflected in global dynamical response of the protein complex. Chromatophore membranes from LH2-only strains of the photosynthetic bacterium Rhodobacter sphaeroides, with spheroidenone or neurosporene as the major carotenoids, were subjected to high hydrostatic pressure at ambient temperature. Optical spectroscopy conducted at high pressure confirmed rupture of tertiary structure hydrogen bonds...

BACKGROUND: Ureaplasma species (spp.) are the bacteria most often isolated from the amniotic cavity of women with preterm labor or preterm premature rupture of membranes, thus, the link between intrauterine Ureaplasma spp. infection and adverse pregnancy outcome is clearly established. However, as vaginal Ureaplasma spp. colonization is very common in pregnant women, it is not clear why these microorganisms cause ascending infections in some cases but remain asymptomatic in most pregnancies...

Preeclampsia is one of the most serious complications during pregnancy, defined as development of hypertension during late pregnancy affecting other organ systems (proteinuria, thrombocytopenia, renal insufficiency, liver involvement, cerebral symptoms or pulmonary edema). Preeclampsia is known to be associated with significant dyslipidemia, but the cause or mechanism of this metabolic aberration is not clear. Quantitative analysis of cholesterol precursors and metabolites can reveal metabolic signatures of cholesterol, and provide insight into cholesterol biosynthetic and degradation pathways...

OBJECTIVE: Intraventricular hemorrhage (IVH) is a common complication in extremely preterm infants. We aimed to demonstrate that umbilical cord milking (UCM) would reduce the incidence of IVH in this at risk population. STUDY DESIGN: We compared the incidence of IVH in a prospective cohort of consecutively born preterm infants <32 weeks' gestation receiving UCM (n = 33) with a historical cohort that underwent immediate cord clamping (ICC) (n = 36). RESULTS: No significant differences regarding perinatal characteristics were present between both groups except for chorioamnionitis and preterm rupture of membranes which were more frequent in the UCM group...
