Obstetric Thromboprophylaxis: The Swedish Guidelines
Obstetric thromboprophylaxis is difficult. Since 10 years Swedish obstetricians have used a combined risk estimation model and recommendations concerning to whom, at what dose, when, and for how long thromboprophylaxis is to be administrated based on a weighted risk score. In this paper we describe the background and validation of the Swedish guidelines for obstetric thromboprophylaxis in women with moderate-high risk of VTE, that is, at similar or higher risk as the antepartum risk among women with history of thrombosis. The risk score is based on major risk factors (i.e., 5-fold increased risk of thromboembolism). We present data on the efficacy of the model, the cost-effectiveness, and the lifestyle advice that is given. We believe that the Swedish guidelines for obstetric thromboprophylaxis aid clinicians in providing women at increased risk of VTE with effective and appropriate thromboprophylaxis, thus avoiding both over- and under-treatment

Cardiac arrest due to out-of-hospital pulmonary embolism during pregnancy: successful thrombolysis
Introduction:Â Pulmonary embolism (PE) is a rare, severe complication in pregnancy, in which case thrombolysis can be lifesaving but has risks. We aim to highlight actions specific to pregnant women.
Case Description:Â A 24-week pregnant woman developed shortness of breath and experienced sudden cardiac arrest. Cardiopulmonary resuscitation (CPR) was begun immediately in the ambulance and a perimortem caesarean section was performed upon arrival at hospital, but the new-born died. After 55 minutes of CPR, bedside echocardiography revealed right ventricular strain and thrombolysis was given. The uterus was bandaged to minimize blood loss. After massive transfusions and correction of haemostasis, a hysterectomy was performed due to inability of the uterus to contract. After 3 weeks, the patient was discharged in good health and placed on continuous anticoagulant treatment with warfarin.
Discussion:Â Approximately 3% of all out-of-hospital cardiac arrest cases are due to PE. Among the few patients who survive at the scene, thrombolysis can be lifesaving and should be considered in pregnant women with unstable PE. Prompt collaborative diagnostic work-up in the emergency room is necessary. In a pregnant woman with cardiac arrest, a perimortem caesarean section improves the chances of both maternal and fetal survival.
Conclusion:Â Thrombolysis should be considered for patients with PE in pregnancy with the same indications as in a non-pregnant woman. In case of survival, there is profuse bleeding with need for massive transfusions and haemostasis correction. Despite being in very poor condition, the above patient survived and was fully restored to health
Epidemiological analysis of peripartum hysterectomy across nine European countries
Introduction Peripartum hysterectomy is a surgical procedure performed for severe obstetric complications such as major obstetric hemorrhage. The prevalence of peripartum hysterectomy in high-resource settings is relatively low. Hence, international comparisons and studying indications and associations with mode of birth rely on the use of national obstetric survey data. Objectives were to calculate the prevalence and indications of peripartum hysterectomy and its association with national cesarean section rates and mode of birth in nine European countries. Material and methods We performed a descriptive, multinational, population-based study among women who underwent peripartum hysterectomy. Data were collected from national or multiregional databases from nine countries participating in the International Network of Obstetric Survey Systems. We included hysterectomies performed from 22 gestational weeks up to 48 hours postpartum for obstetric hemorrhage, as this was the most restrictive, overlapping case definition between all countries. Main outcomes were prevalence and indications of peripartum hysterectomy. Additionally, we compared prevalence of peripartum hysterectomy between women giving birth vaginally and by cesarean section, and between women giving birth with and without previous cesarean section. Finally, we calculated correlation between prevalence of peripartum hysterectomy and national cesarean section rates, as well as national rates of women giving birth after a previous cesarean section. Results A total of 1302 peripartum hysterectomies were performed in 2 498 013 births, leading to a prevalence of 5.2 per 10 000 births ranging from 2.6 in Denmark to 10.7 in Italy. Main indications were uterine atony (35.3%) and abnormally invasive placenta (34.8%). Relative risk of hysterectomy after cesarean section compared with vaginal birth was 9.1 (95% CI 8.0-10.4). Relative risk for hysterectomy for birth after previous cesarean section compared with birth without previous cesarean section was 10.6 (95% CI 9.4-12.1). A strong correlation was observed between national cesarean section rate and prevalence of peripartum hysterectomy (rho = 0.67, P < .05). Conclusions Prevalence of peripartum hysterectomy may vary considerably between high-income countries. Uterine atony and abnormally invasive placenta are the commonest indications for hysterectomy. Birth by cesarean section and birth after previous cesarean section are associated with nine-fold increased risk of peripartum hysterectomy
Insufficient Sun Exposure Has Become a Real Public Health Problem.
This article aims to alert the medical community and public health authorities to accumulating evidence on health benefits from sun exposure, which suggests that insufficient sun exposure is a significant public health problem. Studies in the past decade indicate that insufficient sun exposure may be responsible for 340,000 deaths in the United States and 480,000 deaths in Europe per year, and an increased incidence of breast cancer, colorectal cancer, hypertension, cardiovascular disease, metabolic syndrome, multiple sclerosis, Alzheimer's disease, autism, asthma, type 1 diabetes and myopia. Vitamin D has long been considered the principal mediator of beneficial effects of sun exposure. However, oral vitamin D supplementation has not been convincingly shown to prevent the above conditions; thus, serum 25(OH)D as an indicator of vitamin D status may be a proxy for and not a mediator of beneficial effects of sun exposure. New candidate mechanisms include the release of nitric oxide from the skin and direct effects of ultraviolet radiation (UVR) on peripheral blood cells. Collectively, this evidence indicates it would be wise for people living outside the tropics to ensure they expose their skin sufficiently to the sun. To minimize the harms of excessive sun exposure, great care must be taken to avoid sunburn, and sun exposure during high ambient UVR seasons should be obtained incrementally at not more than 5-30 min a day (depending on skin type and UV index), in season-appropriate clothing and with eyes closed or protected by sunglasses that filter UVR
A modified surgical approach to women with obstetric anal sphincter tears by separate suturing of external and internal anal sphincter. A modified approach to obstetric anal sphincter injury
<p>Abstract</p> <p>Background</p> <p>Long-term results after obstetric anal sphincter injury (OASI) are poor. We aimed to improve the long-term outcome after OASI by lessening symptoms of anal incontinence.</p> <p>Methods</p> <p>In a prospective study at Malmö University Hospital, twenty-six women with at least grade 3B OASI were classified and sutured in a systematic way, including separate suturing of the internal and external sphincter muscles with monofilament absorbable sutures. The principal outcome assessed by answers given to six questions, was a difference in anal incontinence score, between the study group and two control groups (women with prior OASI [n = 180] and primiparous women delivered vaginally without a diagnose of OASI [n = 100]).</p> <p>Results</p> <p>An anal incontinence score of zero (i.e., no symptoms) was found in 74% of the study group, 47% of the OASI control group, and 66% of the vaginal control group (<it>p </it>= 0.02 and 0.5, as compared to the study group).</p> <p>Conclusions</p> <p>A modified suturing technique was followed by significant improved one-year symptoms of anal incontinence as compared to historical cases.</p
