A 30-year-old woman presenting with hemoptysis followed by acute respiratory distress developed a diagnostic pulmonary radiographic finding, called the sign of the camalote, indicative of ruptured hydatid cyst. Her computed tomography scan demonstrated the characteristic detached parasitic membrane floating on cystic fluid, reminiscent of Amazonian camalote leaves. She was managed successfully surgically. Ruptured hydatid cysts may present as a diagnostic challenge, in which the sign of the camalote may provide an important clue for this serious complication...

In recent years, the incidence of placenta accreta and associated complications has increased significantly. The authors report the case of a pregnant woman in the 5th month of pregnancy for premature rupture of the membranes. The placenta was inserted low. The evolution was marked spontaneous work followed by the expulsion of the fetus. The delivery of the placenta was haemorrhagic and incomplete. Ultrasonic testing showed a placental fragment integrated in the thickness of the myometrium. Conservative treatment with methotrexate was published a few days later and MRI showed that the anterior uterine sac was filled with blood clots associated with pelvic effusion...

Recently, mucosal surfaces, especially fish skin and its secreted mucus, have attracted significant interest from immunologists. Amphiprion clarkii, a member of the family Pomacentridae, lives symbiosis with sea anemones and has a good resistance to common seawater bacterial diseases and parasites owing to the protection from its abundant skin mucus. In the present work, the activity of immune-related enzymes (lysozyme, protease, antiprotease, cathepsin B, alkaline phosphatase and peroxidase), the antibacterial activity against two Gram-positive bacteria and five Gram-negative bacteria, the antiparasitic activity against the pathogen of marine white spot disease (Cryptocaryon irritans theronts) and the physico-chemical stability (to pH and heat) of the skin mucus of A...

Endotoxins are widely distributed toxins in the outer cell-wall membranes of Gram-negative bacteria and other microorganisms. Chronic exposure to endotoxins can induce and exacerbate airway symptoms and diseases. However, the release and degradation of airborne endotoxins from bioaerosol by microwave (MW) irradiation have not yet been reported. This study investigated the distribution and fate of airborne endotoxins during MW irradiation process, as well as the kinetics and thermodynamics of the degradation of airborne endotoxins...

The authors report two cases of extended amniotic fluid embolism (AFE) associated with the birth-giving process with the analysis of their causes and the discussion of the possible pathways through which the amniotic fluid penetrates into maternal blood. A rare cause of amniotic fluid embolism due to the rupture of placental membranes as a result of submembranous hemorrhage is described. The changes in the lungs associated with extended AFE are apparent in the presence of macroscopic emboli formed from the particles of the amniotic fluid...

Introduction Unrealistic expectations of labour in first time mothers can present challenges to physicians and midwives. This study calculated the percentage of “practically perfect” births in nulliparous women, defined as a labour without intervention, an intact perineum and a positive neonatal outcome. Methods: This was a retrospective study of the nulliparous deliveries that occurred in the National Maternity Hospital over two years (2014/2015). To extract the perfect births, we excluded deliveries <37 weeks, induction/pre labour Caesarean Section (CS), Artificial Rupture of Membranes (ARM), oxytocin, fetal blood sample, emergency CS/instrumental deliveries, perineal damage and suboptimal Apgar scores...

INTRODUCTION: Spina bifida is the most common non-lethal congenital birth defect of the central nervous system that causes chronic disability due to the combined effects of local nerve damage and the sequelae of non-communicating hydrocephalus. This abnormality can be identified early in gestation and the damage can be progressive over the course of pregnancy. Advances in fetal treatment have made minimally invasive prenatal surgery a realistic consideration for spina bifida in order to improve the outcome for children affected this condition...

To investigate the effects of acute cold stress (ACS) on chicken heart after cold stimulation, female broilers were raised in either normal (C) or gradually decreasing temperatures (CS I and CS II) for 34 days followed by a 24 h ACS at 7°C. Cardiac tissues were collected from the pre-ACS and ACS time points to analyze the histopathological changes, antioxidant status and the expression of heat shock proteins, inflammatory factors and immune-related cytokines. The CS II heart tissues showed shrunken cell membranes and nuclei, disordered or ruptured myocardial fibers, higher MDA content and upregulation in HSP27, HSP40, HSP70, NF-κB, COX-2, PTGEs, iNOS, TNF-α and IL-4 mRNAs, and in protein levels of HSP40, NF-κB and iNOS and reduction in CAT, GSH-px and SOD activity, as well as HSP90 and IFN-γ levels compared to the control tissues before ACS...

BACKGROUND: Preterm birth (PTB) is a major factor contributing to global rates of neonatal death and to longer-term health problems for surviving infants. Both the World Health Organization and the United Nations consider prevention of PTB as central to improving health care for pregnant women and newborn babies. Current preventative clinical strategies show varied efficacy in different populations of pregnant women, frustrating women and health providers alike, while researchers call for better understanding of the underlying mechanisms that lead to PTB...

Basement membranes are specialized extracellular matrices that underlie arterial wall endothelial cells, with laminin being a key structural and biologically-active component. Hypochlorous acid (HOCl), a potent oxidizing and chlorinating agent, is formed in vivo at sites of inflammation via the enzymatic action of myeloperoxidase (MPO), released by activated leukocytes. Considerable data supports a role for MPO-derived oxidants in cardiovascular disease and particularly atherosclerosis. These effects may be mediated via extracellular matrix damage to which MPO binds...

In low-income and middle-income countries, courses of antibiotics are routinely given to term newborns whose mothers had prolonged rupture of membranes (PROM). Rational antibiotic use is vital given rising rates of antimicrobial resistance and potential adverse effects of antibiotic exposure in newborns. However missing cases of sepsis can be life-threatening.This is a quality improvement evaluation of a protocol for minimal or no antibiotics in term babies born after PROM in Papua New Guinea. Asymptomatic, term babies born to women with PROM >12 hours prior to birth were given a stat dose of antibiotics, or no antibiotics if the mother had received intrapartum antibiotics, reviewed and discharged at 48-72 hours with follow-up...
