Evaluation of volume of the sphenoid sinus according to sex,facial type,skeletal class,and presence of a septum: a cone-beam computed tomographic study

We have used cone-beam computed tomographic (CT) images to retrospectivelyevaluate the influence of sex, skeletal class, facial type, and the presence of septa on the volume of the sphenoid sinus in 172 images from 85 men (mean (SD) age 28 (2) years) and 87 women (mean (SD) age 30 (1) years). Skeletal class and facial type were calculated for each patient from multiplanar reconstructions using NemoCeph® software. Volumetric analysis of the sphenoid sinus was made with the help of the ITK-SNAP® 3.4.0 segmentation software, while the presence or absence of septa in the sphenoid sinus was evaluated with the Carestream 3D Imaging® software 3.4.3. We analysed the results using two-way ANOVA, Student’s independent sample t test, and Fisher’s exact test, as appropriate, and probabilities of <0.05 were accepted as significant. Sex (p = 0.0946), facial type (p = 0.790), and skeletal class (p = 0.120) had no significant influence on the volume of the sphenoid sinus, and nor did the volumes of the right and left sphenoid sinuses (p = 0.0923), or the presence of a septum within the sinus (p = 0.330) in its volume.     

Recipient hypertonic saline infusion prevents cardiac allograft dysfunction

Objective

Hypertonic saline (HTS) has potent immune and vascular effects. We assessed recipient pretreatment with HTS on allograft function in a porcine model of heart transplantation and hypothesized that HTS infusion would limit endothelial and left ventricular (LV) dysfunction following transplantation.

Association of frailty index with perioperative mortality and in-hospital morbidity after elective lower extremity bypass

Objective

The frailty index has been linked to adverse outcomes after surgical procedures. In this study, we evaluated the association between frailty index and outcomes after elective lower extremity bypass (LEB) for lower extremity ischemia.

Catastrophic antiphospholipid syndrome and pregnancy. Clinical report

We have observed the development of a catastrophic antiphospholipid syndrome (CAPS) in a pregnant woman hospitalized at 28 weeks of gestation with a severe preeclampsia. On the same day, an eclampsia attack developed, and an emergency surgical delivery was performed. On the third day, multiorgan failure developed. Examination showed a persistent circulation of lupus anticoagulant, high level of antibodies to cardiolipin, b2-glycoprotein I, and prothrombin. The usual diagnosis of the severe preeclampsia masked a catastrophic antiphospholipid syndrome, exacerbated by the coincident presence of several types of antiphospholipid antibodies. The first pregnancy resulted in a premature birth at 25 weeks, possibly also due to the circulation of antiphospholipid antibodies. The trigger of the catastrophic form development was the pregnancy itself, surgical intervention, and hyperhomocysteinemia. CAPS is the most severe form of antiphospholipid syndrome, manifested in multiple microthrombosis of microcirculation of vital organs and in the development of multiorgan failure against the background of the high level of antiphospholipid antibodies. CAPS is characterized by renal, cerebral, gastrointestinal, adrenal, ovarian, skin, and other forms of microthrombosis. Thrombosis recurrence is typical. Thrombotic microvasculopathy lies at the heart of multiorgan failure and manifests clinically in central nervous system lesions, adrenal insufficiency, and ARDS development. CAPS is a life-threatening condition, therefore, requires an urgent treatment. Optimal treatment of CAPS is not developed. CAPS represent a general medical multidisciplinary problem.

Nutrition in pregnancy

Many pregnant women rely on their health professional for nutrition information during routine antenatal visits. This review offers information to assist health professionals with advising pregnant women of the important nutrition considerations during pregnancy. The roles of some of the key nutrients are discussed, including folic acid, iodine, iron, calcium, and vitamin D. Recommendations for each of the key nutrients are covered and examples of how these can be achieved are presented. The review also details additional nutritional considerations that should be discussed during antenatal consults, including energy balance and weight gain recommendations, the importance of food safety during pregnancy, the recommended safe levels of consumption of vitamin A, caffeine, and fish, and the importance of abstaining from alcohol. Educating and supporting women during pregnancy to make healthy food choices to fulfil their needs and the needs of their growing fetus, will help to promote a healthy start to life.
