Acrylate application of the penis in the surgical treatment of hypospadias in boys: multicenter study

Introduction. One of the most important aspects of the treatment of hypospadias is the use of a postoperative dressing. Currently, many types of dressings are available, with their advantages and disadvantages. The postoperative dressing should be easy to use, able to control edema, prevent bleeding and the formation of hematomas, and prevent other possible complications. In the last decade, there have been publications in which cyanoacrylate adhesives were used with good results in surgical operations on the penis. Materials and methods. The study included 77 boys who underwent correction of the distal form of hypospadias from January 2018 to December 2020. The first group consisted of 47 boys, whose penile skin was applied with cyanoacrylate tissue glue after the operation was completed. The second group included 30 boys who used a standard circular adhesive bandage. All patients received the same type of treatment. Results. In the early postoperative period, 16 (20.78%) patients had various complications associated with bandages, which were distributed according to the Clavien-Dindo classification and assigned to grade I-II, according to clarien-Dingo classification. In the group of acrylate application, five (10.6%) patients needed to perform manipulations on the penis in the form of repeated adhesive application. When using an elastic self-binding bandage, all patients needed to remove the bandage, and 11 (36.7%) patients needed additional bandages (χ2=6.038; p=0.015). Conclusions. The use of acrylate application is an alternative to standard postoperative dressings in the treatment of hypospadias. The technology of use can be easily trained and reproduced by surgical personnel.

CONTRIBUTIONS OF NURSES IN BASIC RESEARCH: DRESSING FIXATION MODEL FOR EXCISIONAL CUTANEOUS WOUNDS OF MICE

Objective: validate method of fixation of dressings on excisional cutaneous wounds of mice. Method: preclinical study. Sample made up of animals of the C57BL/6 strain, which had two excision wounds made in the dorsal region. Different methods and products, widely accepted in clinical practice, for fixing dressings in the animal model were evaluated. The evaluated outcomes were the length of stay of the dressing and the occurrence of adverse events. Results: crepe bandage, microporous tape and self adhesive bandage had a shorter residence time when compared to polyurethane film. This, in turn, varied the time when comparing different marks (E, F, G and H) and number of turns around the animal’s body. With 1 lap, the time varied from <24 to 36 hours. With 2 laps, the marks E and G remained 48 and 96 hours, respectively, and F and H time <24 hours. G-brand film, cut to size 3 cm x 15 cm, giving the mouse body 2 turns, kept the dressing for 96 hours. The skin remained intact, with no adverse event. Conclusion: a dressing fixation model for wounds in mice was created with a product available in Brazil and compatible with the animal’s body structure.

Novel Pressure-Sensitive Adhesive Made from Glutinous Rice Flour

Successfully pressure-sensitive adhesives have been used by many industrial tape and label applications.This tape widely used in daily life of adhesive bandage. In this work, the novel the adhesive is fabricated from glutinous rice flour, gelatin, polyvinyl alcohol, borax, methyl paraben and glycerol. Characteristics of adhesive were then investigated by scanning electron microscopy (SEM), and swelling ratios. Mechanical characterization and tissue adhesive bonding test of the final product were also performed.

Elastic adhesive bandage in low back pain in active and sedentary pregnant women living in Coari, Amazonas

Background: Gestational low back pain is a limiting symptom, which interferes in the activities of daily living and quality of life. There are several scientific findings on the effectiveness and benefits of banding for low back pain, making it necessary to investigate effective and inexpensive non-pharmacological technologies. Objectives: The objective of this study was to compare the effect of elastic adhesive bandage (EAB) in low back pain in active and sedentary pregnant women. Method: Study quasi-experimental, analytical with 33 pregnant women living in the city of Coari (AM). Socio-demographic, obstetrical data on health and low back pain were collected. The bandage was applied like “I”, with two bands in the paravertebral region of the lumbar spine and should remain for 3 days. Pain intensity was assessed by visual analogue pain scale (VAS) during the initial evaluation and after 3 days of the application procedure. For purposes of analysis, the sample was divided into 2 groups: active and sedentary. The Wilcoxon test was used to compare the mean of the low back pain intensity before and after the application of the intra-group bandage. The mean intensity of low back pain after the application of bandaging between groups was analyzed by the Mann-Whitney U test. Significance was accepted for p≤0,05. Results: The mean age was 24.24 (±6.39) and 75.8% reported low back pain at moderate intensity. The pain intensity after application of the EAB was lower in both the active (p=0.039) and the sedentary (p=0.000). There was no difference in pain intensity on day 3 in intragroup analysis (p=0.691). Conclusion: EAB reduced the intensity of low back pain in both active and sedentary pregnant women, however, there was no difference in its effect when the groups were compared.

Clinical Trial of a Novel Starch-Based Adhesive Bandages for Medical Dressing

A typical adhesive bandage comprises of four main parts; the backing is often made of plastic; the adhesive sheet is usually plastic; the adhesive is commonly acrylate; the absorbent pad is often made of cotton. This adhesive bandages are made from starch based adhesive and natural paper, which have no plastic components. A starch-based adhesive bandages are tested on 100 volunteers and the result shows good performances with high confident of safety and efficacy. The raw materials and preparation methods are low cost, easily reproducible and eco-friendly, according to the international standards of medical devices regulation.

Preparation and Characterization of a New Absorbent Pad from Rice Starch

Thisresearch was aimed to studying absorbent pad of adhesive bandage. The absorbent pad made from rice starch composite. This material used for healingprocessofwounds.One component of adhesive bandage is the part contact wound (absorbent pad) that obtained rice starch-based sponge for hemostatic and mixed with povidone-iodine for antibacteria. In this study, we prepared a new absorbent pad from rice starch by lyophilization and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), water absortion, Fourier transform infrared spectroscopy (FTIR), and disk diffusion method. The rice strach content of this pad is up to 94 wt%. The diameter of the porous pad was found to be in the range of 10-100 mm. Water absorption of this pad was 6 times of dry weight. The addition of povidone iodine showed good antibiotic resistant microorganism of the rice sponge.
