Vulvodynia affects about 8% of women, many of whom report a negative impact on their ability to have sexually satisfying relationships. In this study, we examined predictors of sexual satisfaction in 207 women with clinically confirmed vulvodynia. We adapted a model examining resilience in chronic pain patients originally developed by Sturgeon and Zautra to include resilience factors (communication with partner about sexual health and coping strategies) and vulnerable factors (abuse history, pain intensity, rumination). These variables were regressed onto sexual satisfaction. In the full model, only emotion-based rumination was predictive of sexual satisfaction. Thus, focusing on emotion-based rumination in clinical intervention may improve sexual satisfaction.

Antihistamines, mostly H1 antihistamines, administered both topically and systemically, are among the most widely used drugs. While systemically applicable antihistamines are usually taken orally or administered intravenously, while local therapy is used on the eye, nose or skin. Systemic antihistamines are most frequently used during the pollen season (hay fever, asthma) or are used all year round, e.g., for house dust and animal hair allergies. Furthermore, urticaria is a major indication for the use of H1 antihistamines, also as long-term treatment. Although H1 antihistamines are not licensed for pruritus and prurigo, they are frequently used in these diseases. However, since in many diseases with pruritus and prurigo the histamine receptor does not play a decisive role in the pathogenesis of pruritus, they show limited efficacy. Two Cochrane reviews have not shown any significant antipruritic effects of H1 antihistamine treatment in atopic eczema as single therapy or in combination, e.g., with topical glucocorticosteroid therapy. A retrospective case series with a so-called high-dose antihistamine therapy with non-sedating antihistamines was effective in treating chronic pruritus. This article summarizes the possibilities of systemic antihistamines in pruritus, especially with regard to limitations and future prospects.

Seasonality is evident in several aspects of human health and behavior, whereas seasonality in chronic pain is less well studied. We examined seasonal variation in pain severity and pain dissemination, as well as in pain-associated conditions, such as sleep impairment, sleep timing, mental distress, fatigue and physical activity. We also examined if any of these associated conditions moderated the seasonality in pain. This prospective study was conducted in the subarctic municipality of Tromsø, Norway (69º North), on a sample of patients with chronic musculoskeletal pain ( = 56). Data were collected with self-report questionnaires and objective actigraphy measures (7 days) twice: winter and summer. Mixed linear regression models were fitted. A modest seasonality effect was observed in pain severity (highest in summer), but not in pain dissemination. Seasonality with increased physical activity and delayed sleep timing in the summer was also present. The remaining pain-associated self-report or objective measures indicated no seasonality. The season-pain association was not significantly moderated by any of the pain-associated conditions. Previous studies on healthy individuals residing in polar areas have suggested an opposite seasonal effect with delay of the sleep-wake rhythm in winter. Our results based on a clinical sample thus represent a novel finding that needs to be examined further with regard to seasonal circadian entrainment and alignment in pain populations. These results may have clinical value for the treatment of patients with musculoskeletal pain as seasonality may require seasonal adjustments of pain treatment strategies.

Posterior reversible encephalopathy syndrome (PRES) is a neurological disorder which is characterised by variable symptoms, which include visual disturbances, headache, vomiting, seizures and altered consciousness. The exact pathophysiology of PRES has not been completely explained, but hypertension and endothelial injury seem to be almost always present. Vasoconstriction resulting in vasogenic and cytotoxic edema is suspected to be responsible for the clinical symptoms as well as the neuro-radiological presentation. On imaging studies, Symmetrical white matter abnormalities suggestive of edema are seen in the computer tomography (CT) and magnetic resonance imaging (MRI) scans, commonly but not exclusively in the posterior parieto-occipital regions of the cerebral hemispheres. The management is chiefly concerned with stabilization of the patient, adequate and prompt control of blood pressure, prevention of seizures and timely caesarean section in obstetric cases with pre-eclampsia/eclampsia. In conclusion, persistently elevated blood pressures remain the chief culprit for the clinical symptoms as well as the neurological deficits. Early diagnosis by diffusion weighted MRI scans, and differentiation from other causes of altered sensorium i.e. seizures, meningitis and psychosis, is extremely important to initiate treatment and prevent further complications. Although most cases resolve successfully and carry a favorable prognosis, patients with inadequate therapeutic support or delay in treatment may not project a positive outcome.

It is unclear whether regional anesthesia with infraclavicular nerve block or general anesthesia provides better postoperative analgesia after distal radial fracture fixation, especially when combined with regular postoperative analgesic medications. The aim of this study was to compare the postoperative analgesic effects of regional versus general anesthesia.

To compare the effectiveness of a paravertebral nerve block vs local portal blocks for laparoscopic closure of the nephrosplenic space in standing sedated research horses.

Chronic kidney disease (CKD) is a health condition that threatens patient safety; however, few interventions provide patient-centered education about kidney-specific safety hazards.

Medication-overuse headache (MOH) is a common debilitating neurological disorder, with a prevalence of 1% to 7% in general population. It affects more than 60 million people worldwide and provokes substantial burden. Despite that, most practitioners don't know MOH. This review aims at presenting MOH clinical features, pathophysiology insights, and recent knowledge and guidance regarding treatments.

Thrombin converts fibrinogen to fibrin and activates blood and vascular cells in thrombo-inflammatory diseases. Platelets are amplifiers of thrombin formation when activated by leukocyte- and vascular cell-derived thrombin. CD36 on platelets acts as sensitizer for molecules with damage-associated molecular patterns, thereby increasing platelet reactivity. Here, we investigated the role of CD36 in thrombin-generation on human platelets, including selected patients with advanced chronic kidney disease (CKD). Platelets deficient in CD36 or blocked by anti-CD36 antibody FA6.152 showed impaired thrombin generation triggered by thrombin in calibrated automated thrombography. Using platelets with congenital function defects, blocking antibodies, pharmacological inhibitors, and factor-depleted plasma, CD36-sensitive thrombin generation was dependent on FXI, fibrin, and platelet signaling via GPIbα and SFKs. CD36-deficiency or blocking suppressed thrombin-induced platelet αIIbβ3 activation, granule exocytosis, binding of adhesion proteins and FV, FVIII, FIX, FX, but not anionic phospholipid exposure determined by flow cytometry. CD36 ligated specifically soluble fibrin, which recruited distinct coagulation factors via thiols. Selected patients with CKD showed elevated soluble fibrin plasma levels and enhanced thrombin-induced thrombin generation, which was normalized by CD36 blocking. Thus, CD36 is an important amplifier of platelet-dependent thrombin generation when exposure of anionic phospholipids is limited. This pathway might contribute to hypercoagulability in CKD.
