SummaryBackground: This study is about CLaCS, a new technique to treat telangiectasias and feeder veins.Method: A series of 140 cases were treated under Augmented Reality guidance in a completely different way. Sclerosis was achieved by combination of thermal and chemical agents: laser and dextrose. Patients were classified according to two questions: presence of varicose veins and/or reflux on the saphenous vein; presence of telangiectasias and/or feeder veins (Score 9–1). Duplex ultra-sound and Augmented Reality (VeinViewer) were used to detect reflux and feeder veins, respectively. Feeder veins and telangiectasias were treated the same way, in the same procedure, by a combination of Nd:YAG 1064 nm with spot sizes of 6mm, 15 msec pulse and fluence of up to 80 J/cm2 followed by injection sclerotherapy of Dextrose 75%. Both techniques were done under forced air skin cooling (Cryo5). A thorough photodocumentation was done prior and after each procedure and results were obtained by comparing before and after photos on two iPads. Response to the treatment was rated on: total or partial improvement with patient satisfaction (Group 1); partial improvement or lack of resolution, without patient satisfaction (Group 2).Results: A total of 466 patients visited the clinic during the study and exclusion criteria left a total of 140 patients for analysis. Mean age of patients was 37 years (16 to 72), with prevalence of women (98 %). No allergic reactions, systemic reactions, skin burns, post-sclerotherapy mattings, infections or crustings were observed. Temporary ecchymosis were observed in 30 % of the cases, and intravenous coagula in 14 % of them. No frostbite was registered due to cold air blowing. Partial or total lesion improvement was obtained in 121 patients (86 %), with satisfactory cosmetic results. Unsatisfactory outcome was observed in 19 patients (14 %) due to no response or lesion worsening, thus crochet hook phlebectomy was indicated.Conclusion: CLaCS guided by Augmented Reality is a very effective option to treat telangiectasias, reticular and feeder veins. It is a safe method based on the employment of technology and an organic sclerosing agent. It dispenses the use of any other medication, thus being free of risk of anaphylaxis or embolism.

Before And After

A 68-year-old man with hemophilia A and liver cirrhosis caused by hepatitis C virus was referred to our hospital to receive prophylactic endoscopic treatment for gastroesophageal varices (GOV). He had large, tense, and winding esophageal varices (EV) with cherry red spots extending down to lesser curve, predicting the likelihood of bleeding. Esophageal endoscopic injection sclerotherapy (EIS) was performed with a total 15 mL of 5% ethanolamine oleate with iopamidol (EOI). Radiographic imaging during EIS demonstrated that 5% EOI reached the afferent vein of the varices. He was administered sufficient factor VIII concentrate before and after EIS to prevent massive bleeding from the varices. Seven days after EIS, upper gastrointestinal endoscopy (UGIE) showed that the varices were eradicated almost completely. Eighteen months after EIS, the varices continued to diminish. We report a successful case of safe and effective EIS for GOV in a high-risk cirrhotic patient with hemophilia A.

Abstract Background The study was to investigate the role of color Doppler ultrasonography in the evaluation of the effect of Rex-bypass shunt on the cavernous transformation of the portal vein (CTPV) in children. Methods Fifty children with symptomatic extrahepatic portal hypertension who received Rex-bypass shunt were retrospectively reviewed, and they were diagnosed with CTPV by ultrasonography. The clinical characteristics were analyzed before and after operation. Results Forty-five patients received color Doppler ultrasonography at 6 months after surgery, and good patency in the bypass vessels was displayed. The platelet count significantly increased (P < 0.001) and the esophagogastric varices were improved significantly (p < 0.001). The patency of bypass vessels on color Doppler ultrasonography was consistent with the changes in the platelet count and the degree of esophagogastric varices on gastroscopy before and after operation. The diameter of bypass vessels at 6 months was slightly larger than that at 7 days after operation, and there was no significant difference in blood flow velocity between two time points (P = 0.507). Conclusions Color Doppler ultrasonography can display the patency, diameter, and flow velocity of bypass vessels. It plays an important role in evaluating the effect of Rex-bypass shunt on the CTPV.

Challenging Situation

Background. Esophagogastric variceal hemorrhage leads to challenging situation in chronic kidney disease patients on maintenance hemodialysis. Aims. To determine the safety and efficacy of endoscopic approaches to patients with hemodialysis-dependent concomitant with esophagogastric varices. Methods. Medical records were reviewed from January 1, 2004, to December 31, 2015, in our hospital. Five consecutive hemodialysis-dependent patients with variceal hemorrhage who underwent endoscopic treatments were retrospectively studied. Results. The median age of the patients was 54 years (range 34–67 years) and the median follow-up period was 21.3 months (range 7–134 months). All the patients received a total of three times heparin-free hemodialysis 24 hours before and no more than 24 hours and 72 hours after endoscopic treatment. They successfully had endoscopic variceal ligation, endoscopic injection sclerotherapy, and/or N-butyl cyanoacrylate injection. The short-term efficacy is satisfying and long-term follow-up showed episodes of rebleeding. Conclusions. Endoscopic approaches are the alternative options in the treatment of upper gastroenterology variceal hemorrhage in hemodialysis-dependent patients without severe complications.

Tool materials used in ultramicrotomy are glass, developed by Latta and Hartmann (1) and diamond, introduced by Fernandez-Moran (2). While diamonds produce more good sections per knife edge than glass, they are expensive; require careful mounting and handling; and are time consuming to clean before and after usage, purchase from vendors (3-6 months waiting time), and regrind. Glass offers an easily accessible, inexpensive material ($0.04 per knife) with very high compressive strength (3) that can be employed in microtomy of metals (4) as well as biological materials. When the orthogonal machining process is being studied, glass offers additional advantages. Sections of metal or plastic can be dried down on the rake face, coated with Au-Pd, and examined directly in the SEM with no additional handling (5). Figure 1 shows aluminum chips microtomed with a 75° glass knife at a cutting speed of 1 mm/sec with a depth of cut of 1000 Å lying on the rake face of the knife.

Phosgene still plays an important role as a toxic substance in the chemical industry. Thiess (1968) recently reported observations on numerous cases of phosgene poisoning. A serious difficulty in the clinical handling of phosgene poisoning cases is a relatively long latent period, up to 12 hours, with no obvious signs of severity. At about 12 hours heavy lung edema appears suddenly, however changes can be seen in routine X-rays taken after only a few hours' exposure (Diller et al., 1969). This study was undertaken to correlate these early changes seen by the roengenologist with morphological alterations in the lungs seen in the'light and electron microscopes.Forty-two adult male and female Beagle dogs were selected for these exposure experiments. Treated animals were exposed to 94.5-107-5 ppm phosgene for 10 min. in a 15 m3 chamber. Roentgenograms were made of the thorax of each animal before and after exposure, up to 24 hrs.
