Craniofacial venous malformations treated by percutaneous sclerotherapy using polidocanol: a single-center experience.

2018

Background Percutaneous therapy with various sclerosants is an established treatment of venous malformations in general. We investigated the safety and effectiveness of polidocanol in the craniofacial region. Purpose To present and evaluate our subjective and objective mid- and long-term results of patients with craniofacial venous malformations (CFVM) after percutaneous sclerotherapy using polidocanol. Material and Methods Twenty patients with CFVM treated by percutaneous sclerotherapy were followed up and asked to fill in a questionnaire comparing levels of the following CFVM-related symptoms before and after treatment: pain; functional impairment; cosmetic deformities; and impairment in …

Acetylcholine overflow during infusion of a high potassium-low sodium solution into the perfused chicken heart in the absence and presence of physost…

1977

1. The effect of infusion of a modified Tyrode's solution (“high K+-low Na+ solution”) into the isolated chicken heart on the content of acetylcholine in the tissue and the overflow of acetylcholine were compared to those evoked by vagal stimulation. 2. The release of acetylcholine was measured over 15-min periods of either stimulation of the vagus nerves (40 V, 1 ms) at 20 Hz or of infusion of the high K+-low Na+ solution (108 mM K+, 44 mM Na+). 3. Both stimuli caused a maximum overflow of acetylcholine in the first few minutes whether or not 10−6 M physostigmine was present. The overflow was maintained during the vagal stimulation at a constant rate of at least 35% the initial rate, where…

Innovative barriers for peritoneal adhesion prevention: liquid or solid? A rat uterine horn model.

2005

Objective To compare the effects of solid barriers (PDLA membrane and foil, Interceed), innovative barrier solutions (Adept and Hyalobarrier Gel, phospholipid emulsion), and Ringer’s lactate solution in preventing postsurgical peritoneal adhesions in the rat. Design Prospective, randomized experimental study. Setting Rat model in an academic research environment. Animal(s) Female, nonpregnant Wistar rats. Intervention(s) Standardized surgical injuries were applied to the parietal and visceral peritoneum and the uterine horns. The barrier agents were applied and the wound was closed. A second-look laparoscopy was performed 31 days after surgery to assess adhesion formation. Main Outcome Meas…

Albumin replacement therapy in immunocompromised patients with sepsis - Secondary analysis of the ALBIOS trial

2021

Abstract Background The best fluid replacement strategy and the role of albumin in immunocompromised patients with sepsis is unclear. Methods We performed a secondary analysis of immunocompromised patients enrolled in the ALBIOS trial which randomized patients with severe sepsis or septic shock to receive either 20% albumin (target 30 g per liter or more) and crystalloid or crystalloid alone during ICU stay. Results Of 1818 patients originally enrolled, 304 (16.4%) were immunocompromised. One-hundred-thirty-nine (45.7%) patients were randomized in the albumin while 165 (54.2%) in the crystalloid group. At 90 days, 69 (49.6%) in the albumin group and 89 (53.9%) in the crystalloids group died…

Survey of root canal irrigating solutions used in dental practices within Germany.

2014

Aim Irrigant usage information in relation to years of professional experience was collected from general dentists in different German federal states by means of a questionnaire. Methodology A short survey concerning endodontic treatment and use of irrigants was mailed to 4240 dentists or delivered to 3720 dental offices as an extra page in a journal in eight German states. Detailed information concerning the most frequently used irrigants, their concentrations, the spectrum of disinfectants used in root canal treatment concepts for vital and nonvital pulps, main topics of continuing education as well as years of professional experience was collected. The statistical analysis of differences…

Modulation of central corneal thickness by various riboflavin eyedrop compositions in porcine corneas

2012

Purpose To evaluate the modulatory effect of various riboflavin 0.1% and 0.2% compositions on the central corneal thickness (CCT) in fresh porcine corneas. Setting Department of Ophthalmology, Johannes Gutenberg University of Mainz, Mainz, Germany. Design Experimental study. Methods The CCT in freshly enucleated porcine globes was measured by ultrasound pachymetry before and after (if applicable) deepithelialization and every 10 minutes thereafter during 120 minutes of eyedrop application. In Groups 1 and 2 (controls), no eyedrops were applied. In Groups 3 and 4, isotonic riboflavin eyedrops were used. In Groups 5 to 9, hypotonic riboflavin eyedrops were given. In Groups 10 and 11, preparat…

Patient and ophthalmologist attitudes concerning compliance and dosing in glaucoma treatment.

2005

The aim of this study was to identify research avenues that might improve patient compliance with glaucoma therapy.500 patients and physicians were interviewed by telephone in 5 European countries, and the results were compiled and evaluated by 2 independent physicians.Most physicians believed that pressure reduction is useful (UK (96%), France (94%), Spain (80%), Italy (72%), and Germany (70%), p0.0001). The majority of physicians believed that noncompliance exists in 0%-25% of patients, whereas 34% of patients admitted to noncompliance. Physicians believed patients would prefer once-daily dosing (92%) and that it would help compliance, whereas 60% of patients preferred once-daily dosing, …

Transpenile Venenokklusion zur Therapie der erektilen Impotenz

1989

In 15 of 18 patients, 2 of them with previous surgery, transpenile venoablation was performed for treatment of erectile dysfunction due to cavernous leakage. In 4 this was combined with retrograde venooclusion via the internal iliac vein. In 4 patients normal erectile status could be obtained. In 3 other patients erections became possible with use of intracavernous vasoactive agents. In two only mild amelioration, and in two others no change of erectile dysfunction were obtained. Follow-up studies are yet missing in 3 patients. Complications of the procedure were not observed.

The effect of the calibre and length of needle on the stability of sclerosing foam.

2020

Objectives Little is known how calibre and length of needles affect the stability of sclerosing foam. Methods Foams were made of 0.5%, 1%, 2% and 3% polidocanol, and 0.2%, 0.5%, 1% and 3% sodium tetradecyl sulfate (STS), which were mixed with air in the proportion of 4:1. These foams were ejected through needles with the length of: 4 mm, 6 mm and 13 mm, and diameter of: 0.26 mm, 0.3 mm and 0.4 mm. Results Foams made of more concentrated polidocanol were more stable. Regarding STS an opposite relationship was revealed. Foams made of polidocanol were more stable if ejected through a longer needle, while the length of needle did not significantly affect stability of STS foams. Foams ejected th…
