Amniotic Fluid Embolism. Is a New Pregnancy Possible? Case Report.

Amniotic fluid embolism (AFE) is a rare but potentially catastrophic clinical condition, characterized by a combination of signs and symptoms that reflect respiratory distress, cardiovascular collapse and disseminated intravascular coagulation (DIC). Its pathogenesis is still unclear. More recently, the traditional view of obstruction of pulmonary capillary vessels by amniotic fluid emboli as the main explanation for the etiology has been ruled out, and immunologic factors and the activation of the inflammatory cascade took on an important role. Amniotic fluid embolism has an unpredictable character, its diagnosis is exclusively clinical, and the treatment consists mainly of cardiovascular support and administration of blood products to correct the DIC. No diagnostic test is recommended until now, though multiple blood markers are currently being studied. The authors present a case report of a woman who had survived AFE in her previous pregnancy and had a subsequent pregnancy without recurrence, providing one more clinical testimony of the low risks for the pregnancy after AFE.info:eu-repo/semantics/publishedVersio

Histerectomia pós-parto: revisão de 15 anos

Overview and Aims: Postpartum Hysterectomy (PPH) is considered an obstetrical emergency. Profuse bleeding, the most common indication, may jeopardize the puerperal woman. If not controlled by conservative measures, it may require PPH. Its incidence varies between 0.13 to 5.38 per 1000 births. Women with underlying conditions such as placenta previa, fi- broleiomyomas or previous cesarean section (CS) are at increased risk. We evaluated the incidence of PPH, its indications, risk factors and complications. Material and Methods: Retrospective study of PPH conducted at a tertiary care hospital in 15 years (1997-2011). Results: We found 41 cases of PPH (0.6 per 1000 births). Twenty eight occurred after CS (1.34 /1000) and 13 followed vaginal deliveries (0.27/1000), resulting in an odds ratio of 4.94 (2.56 to 9.54, p < 0.001) for CS vs vaginal delivery. Sixteen patients had a previous uterine surgery (CS and/or curettage) and 8 were nulliparous. The most common indication was uterine atony in 18 cases (43.9 %), followed by unspecified hemorrhage in 8 (19.5 %), placenta accreta in 7 (17.1%) and uterine dehiscence/rupture in 4 (9.8%). In 30 cases it was performed a total hysterectomy, being subtotal in the remaining 11 cases. The main complications were the need for red blood cell transfusion (39), disseminated intravascular coagulation (8) and febrile syndrome (6); 21 postpartum women were admitted in Intensive Care Unit. There were no maternal deaths. Pathologic examination of uterus and placenta showed normal postpartum changes in 11 (26.8 %), placenta accreta in 12 (29.3 %), changes consistent with uterine atony in 8 (19.5 %), fibroleiomyomas in 5 (12.2%) and uterine rupture in 3 (7.3%). Conclusions: hysterectomy remains a required procedure in the treatment of postpartum bleeding resistant to conservative management, being uterine atony the most frequent indication with CS accounting for a five times higher risk than vaginal delivery

Doença inflamatória pélvica: um desfecho inesperado

Pelvic inflammatory disease is a polymicrobial infection of the upper genital tract, representing the most common complication of sexually transmitted diseases. Multiple agents are frequently involved, although some unusual agents have also been reported. The presentation is frequently sub-clinical, but may assume an acute form. We report a clinical case of a 39-year-old woman with recurrent pelvic inflammatory disease, resistant to systemic antibiotics, submitted to an exploratory surgery, with a histologic finding of tubal cysticercosis

A pilot study of rivastigmine in the treatment of delirium after stroke: A safe alternative

<p>Abstract</p> <p>Background</p> <p>Delirium is a common disorder in the early phase of stroke. Given the presumed cholinergic deficiency in delirium, we tested treatment with the acetylcholinesterase inhibitor rivastigmine.</p> <p>Methods</p> <p>This pilot study was performed within an epidemiological study. In 527 consecutive stroke patients presence of delirium was assessed during the first week with the confusion assessment method. Severity was scored with the delirium rating scale (DRS). Sixty-two patients developed a delirium in the acute phase of stroke. Only patients with a severe and persistent delirium (defined as a DRS of 12 or more for more than 24 hours) were enrolled in the present study. In total 26 fulfilled these criteria of whom 17 were treated with orally administered rivastigmine with a total dose between 3 and 12 mg a day. Eight patients could not be treated because of dysphagia and one because of early discharge.</p> <p>Results</p> <p>No major side effects were recorded. In 16 patients there was a considerable decrease in severity of delirium. The mean DRS declined from 14.8 on day one to 8.5 after therapy and 5.6 after tapering. The mean duration of delirium was 6.7 days (range; 2–17).</p> <p>Conclusion</p> <p>Rivastigmine is safe in stroke patients with delirium even after rapid titration. In the majority of patients the delirium improved after treatment. A randomized controlled trial is needed to establish the usefulness of rivastigmine in delirium after stroke.</p> <p>Trial registration</p> <p>Nederlands Trial Register NTR1395</p

Prevalence of Dirofilaria immitis, Ehrlichia canis, Borrelia burgdorferi sensu lato, Anaplasma spp. and Leishmania infantum in apparently healthy and CVBD-suspect dogs in Portugal - a national serological study

<p>Abstract</p> <p>Background</p> <p>Canine vector-borne diseases (CVBDs) are caused by a wide range of pathogens transmitted to dogs by arthropods including ticks and insects. Many CVBD-agents are of zoonotic concern, with dogs potentially serving as reservoirs and sentinels for human infections. The present study aimed at assessing the seroprevalence of infection with or exposure to <it>Dirofilaria immitis, Ehrlichia canis, Borrelia burgdorferi </it>sensu lato, <it>Anaplasma </it>spp. and <it>Leishmania infantum </it>in dogs in Portugal.</p> <p>Methods</p> <p>Based on 120 veterinary medical centres from all the regions of mainland and insular Portugal, 557 apparently healthy and 628 CVBD-suspect dogs were sampled. Serum, plasma or whole blood was tested for qualitative detection of <it>D. immitis </it>antigen and antibodies to <it>E. canis, B. burgdorferi </it>s. l., <it>Anaplasma </it>spp. and <it>L. infantum </it>with two commercial in-clinic enzyme-linked immunosorbent assay kits. Odds ratios (OR) were calculated by logistic regression analysis to identify independent risk factors of exposure to the vector-borne agents.</p> <p>Results</p> <p>Total positivity levels to <it>D. immitis, E. canis, B. burgdorferi, Anaplasma </it>spp., <it>L. infantum</it>, one or more agents and mixed agents were 3.6%, 4.1%, 0.2%, 4.5%, 4.3%, 14.0% and 2.0% in the healthy group, and 8.9%, 16.4%, 0.5%, 9.2%, 25.2%, 46.3% and 11.6% in the clinically suspect group, respectively. Non-use of ectoparasiticides was a risk factor for positivity to one or more agents both in the apparently healthy (OR = 2.1) and CVBD-suspect (OR = 1.5) dogs. Seropositivity to <it>L. infantum </it>(OR = 7.6), <it>E. canis </it>(OR = 4.1) and <it>D. immitis </it>(OR = 2.4) were identified as risk factors for the presence of clinical signs compatible with CVBDs. Positivity to mixed agents was not found to be a risk factor for disease.</p> <p>Conclusions</p> <p>Dogs in Portugal are at risk of becoming infected with vector-borne pathogens, some of which are of zoonotic concern. CVBDs should be considered by practitioners and prophylactic measures must be put in place to protect dogs and limit the risk of transmission of vector-borne agents to humans. This study is expected to give veterinary and public health authorities an increased awareness about CVBDs in Portugal and to serve as a reference for future investigations and control actions.</p
