Endovenous laser ablation combined with high ligation is safe and effective. Postoperative hematomas are significantly smaller than those after stripping. Short-term quality of life is at least as good as that after stripping. The long-term results warrant further investigation.

Severe itching for unknown reasons has been reported after administration of hydroxyethylstarch (HES) in haemodilution therapy of humans. After HES treatment, vacuoles in cells of various organs in humans have been shown, predominantly affecting the mononuclear phagocyte system. These vacuoles present indirect evidence for phagocytosis of HES particles. Since phagocytosis is also known to occur in the skin, this organ might represent a target for HES deposition, resulting in subsequent release of mediators responsible for the observed itching. The aim of the present investigation was to study skin biopsies of patients, who had received HES and suffered subsequently from itch. Skin sections were investigated for morphological impairment by means of light and electron microscopy, immunohistochemistry and immunoelectron microscopy using a polyclonal anti-HES antiserum. Storage of HES was demonstrated in the skin of all patients, mainly in dermal macrophages, endothelial cells of blood and lymph vessels, some perineural cells and endoneural macrophages of larger nerve fascicles, some keratinocytes and Langerhans cells. Treatment with antihistaminic agents proved ineffective in these patients; this fits with the observation that morphological signs of histamine release from mast cells were absent. These findings indicate that other mediators from HES-affected cells must be responsible for the development of the itching. Thus, investigation of HES storage may be a useful contribution to the elucidation of release of itch mediators and induction of pruritus.

Deeply infiltrating endometriosis is well characterized using the Enzian classification as a supplement to the rASRM score. There is also a clear correlation between the rASRM and Enzian classifications, because of the way in which the disease crosses morphological boundaries. The locations in the Enzian classification correlate partially with clinical symptoms, and the classification's severity grades correlate substantially with pain and dysmenorrhea. In view of these clinical results, use of the Enzian classification can be recommended as a supplement to the rASRM score for detailed description of endometriosis.

IntroductionThe aim of this study was to evaluate odor identification testing as a quick, cheap, and reliable tool to identify PD.MethodsOdor identification with the 16‐item Sniffin' Sticks test (SS‐16) was assessed in a total of 646 PD patients and 606 controls from three European centers (A, B, and C), as well as 75 patients with atypical parkinsonism or essential tremor and in a prospective cohort of 24 patients with idiopathic rapid eye movement sleep behavior disorder (center A). Reduced odor sets most discriminative for PD were determined in a discovery cohort derived from a random split of PD patients and controls from center A using L1‐regularized logistic regression. Diagnostic accuracy was assessed in the rest of the patients/controls as validation cohorts.ResultsOlfactory performance was lower in PD patients compared with controls and non‐PD patients in all cohorts (each P < 0.001). Both the full SS‐16 and a subscore of the top eight discriminating odors (SS‐8) were associated with an excellent discrimination of PD from controls (areas under the curve ≥0.90; sensitivities ≥83.3%; specificities ≥82.0%) and from non‐PD patients (areas under the curve ≥0.91; sensitivities ≥84.1%; specificities ≥84.0%) in all cohorts. This remained unchanged when patients with >3 years of disease duration were excluded from analysis. All 8 incident PD cases among patients with idiopathic rapid eye movement sleep behavior disorder were predicted with the SS‐16 and the SS‐8 (sensitivity, 100%; positive predictive value, 61.5%).ConclusionsOdor identification testing provides excellent diagnostic accuracy in the distinction of PD patients from controls and diagnostic mimics. A reduced set of eight odors could be used as a quick tool in the workup of patients presenting with parkinsonism and for PD risk indication. © 2016 The Authors.

Background. Jehovah's Witnesses (JW) refuse allogeneic blood transfusions and therefore pose a unique challenge in case of major surgery. This retrospective study reviewed an experience with JW patients who were undergoing open heart surgery.Methods. By using patient blood management strategies, 35 adult JW patients underwent cardiac surgery at Kepler University Hospital in Linz, Austria between 2008 and 2017. Outcomes were compared with patients who accepted blood transfusions (non-JW patients) by using propensity score matching.Results. There were no significant differences in clinical and operative data between the groups. Twelve JW patients (34.3%) were pretreated with erythropoietin and iron, with a preoperative increase in mean hemoglobin of 2.0 g/dL. On admission, hemoglobin was 14.1 ± 1.1 g/dL in JW patients, compared with 13.2 ± 2.0 g/dL in non-JW patients (P [ .022). The hematocrit in JW patients was higher throughout the hospital stay, even though 51.4% of non-JW patients received allogeneic red blood cell transfusions. The perioperative red blood cell loss was significantly lower in JW patients than in non-JW patients (619 ± 420 mL vs 929 ± 520 mL; P [ .010). Major complication rates were not different between the groups. The hemoglobin at discharge was 11.5 ± 1.5 g/dL in JW patients compared with 10.3 ± 1.3 g/dL in non-JW patients (P < .001). In-hospital mortality was 2.9% in each group, and long-term survival was comparable.Conclusions. By implementing patient blood management, open heart surgery in JW patients can be performed with low morbidity and mortality. Preoperative optimization of hemoglobin and minimization of perioperative blood loss are cornerstones in the prevention of blood loss, anemia, and transfusions.

Our data add evidence to the impact of platelet and WBC counts on thrombosis in ET. We suspect a particular interaction between platelets and WBC which might be based on a biological interplay depending on particular cell counts.
