    One of the promising directions of the use of expansive cements is making the protective bandages for the maintenance of pipelines. Bandages expansive application of the compositions of the pipeline reinforce the damaged area and reduce stress due to compressive stress in the cylindrical area. Such requirements are best suited for expansive compositions obtained from portland cement and modified quicklime. The article presents the results of expansive cements based on quick lime in order to implement protective bandages pipelines.

    A 76 year old male presents with a corneal perforation in a phthisical eye. Definitive treatment in the form of an evisceration was delayed by 38 days. During this period a bandage contact lens prevented extrusion of ocular contents through an enlarging corneal perforation. This case demonstrates that a bandage contact lens can be effective in the immediate management of large corneal perforations whilst awaiting urgent definitive treatment.

    Full Text Available In current compression practice for the treatment of chronic venous disorders, there has always been a challenge of controlled compression by a bandage to achieve a particular pressure range in the affected region of the limb. The challenges in compression in the products could be solved if there were the possibility of stress control in fabric. Herein, we are exploiting the newly discovered phenomena, i.e., stress memory, in a memory polymer (MP for the design and investigation of a smart bandage for functional compression benefits. A memory bandage is developed using a blend yarn consisting of MP filaments (segmented polyurethane and nylon filaments. Results showed the possibility to control or manage the internal stress developed in the bandage in wrapped position by simple heating, and thus allowing pressure readjustment externally. Extra pressure generated by the bandage increases with increasing the level of temperature and strain (p < 0.05. The pressure variations also depend on the number of layers and limb circumference (p < 0.05. The memory bandage could have a great potential over existing conventional compression products, as they could give more freedom to govern pressure level whenever needed during the course of compression therapy as a novel wound care management system.

    Compression garments are special textile products which apply a pressure on needed body zones for supporting medical, sport or casual activities. Medical bandages are a group of these garments and they have a very common usage for compression effect on legs or arms. These bandages are generally produced by using synthetic raw materials such as polyamide or polyester fibres. Medical bandages are in contact with skin. Even if the synthetic fibres are used, they may cause both comfort and health problems like allergies. Nowadays in textile sector, the expectations of clients include using of natural fibres as far as possible in all garments. Natural fibres have good advantages such as breathability, softness, moisture management ability, non-allergenic and ecologic structure and these characteristics present optimum utilization conditions. In this study, tubular medical bandages were manufactured by using core spun yarns (sheath fibres are selected as tencel, bamboo and cotton, core material is elastane) and their pressure and comfort (air and water vapour permeability) characteristics were investigated. The results indicated that the bandages have good comfort abilities beside adequate pressure values for compression effect. These garments can constitute a new production field for medical bandages with their comfort properties in addition to pressure characteristics.

    Restoring tissue oxygenation has the potential to improve poorly healing wounds with impaired microvasculature. Compared to more established wound therapy using hyperbaric oxygen chambers, topical oxygen therapy has lower cost and better patient comfort, although topical devices have provided inconsistent results. To provide controlled topical oxygen while minimizing moisture loss, a major issue for topical oxygen, we’ve devised a novel wound bandage based on microfluidic diffusion delivery of oxygen. In addition to modulating oxygen from 0–100% in 60s rise time, the microfluidic oxygen bandage provides a conformal seal around the wound. When 100% oxygen is delivered, it penetrates wound tissues as measured in agar phantom and in vivo wounds. Using this microfluidic bandage, we applied the oxygen modulation to 8 mm excisional wounds prepared on diabetic mice. Treatment with the microfluidic bandage demonstrated improved collagen maturity in the wound bed, although only marginal differences were observed in total collagen, microvasculature, and external closure rates. Our results show that proper topical oxygen can improve wound parameters underneath the surface. Because of the ease of fabrication, the oxygen bandage represents an economical yet practical method for oxygen wound research. PMID:23438079

    Full Text Available Introduction Functional bandages have been used in physiotherapeutic practice with the purpose of minimizing disabilities and favoring functional improvement. However, there is still a shortage of research regarding the use of these devices in patients with neurological sequelae, especially those resulting from stroke. Objective To report the motor evolution of patients living with sequelae of stroke, who have been submitted to the use of functional bandages associated with conventional physical therapy. Materials and methods We assessed the active range of motion, strength and degree of spasticity in the flexor and extensor muscles of the wrist and elbow joints, and functionality of the upper limb during the performance of daily activities at the first and the twentieth session of conventional physical therapy associated with the use of functional bandages. Results There was an increase in range of motion and muscle strength of patients, and reduction in spasticity of the wrist and elbow flexor muscles. Conversely, the functionality scores remained similar before and after treatment. Conclusion The subjects of this study showed a good evolution in the aspects studied. Thus, the use of functional bandages associated with conventional physical therapy seems to contribute to the rehabilitation of patients with stroke sequelae. Further research needs to be conducted in order to increase the scientific evidence regarding the effectiveness of functional bandages in the treatment of patients with stroke sequelae.

    Wearable bendable bandage-based sensor and a minimally invasive microneedle biosensor are described toward rapid screening of skin melanoma. These wearable electrochemical sensors are capable of detecting the presence of the tyrosinase (TYR) enzyme cancer biomarker in the presence of its catechol substrate, immobilized on the transducer surface. In the presence of the surface TYR biomarker, the immobilized catechol is rapidly converted to benzoquinone that is detected amperometrically, with a current signal proportional to the TYR level. The flexible epidermal bandage sensor relies on printing stress-enduring inks which display good resiliency against mechanical deformations, whereas the hollow microneedle device is filled with catechol-coated carbon paste for assessing tissue TYR levels. The bandage sensor can thus be used directly on the skin whereas microneedle device can reach melanoma tissues under the skin. Both wearable sensors are interfaced to an ultralight flexible electronic board, which transmits data wirelessly to a mobile device. The analytical performance of the resulting bandage and microneedle sensing systems are evaluated using TYR-containing agarose phantom gel and porcine skin. The new integrated conformal portable sensing platforms hold considerable promise for decentralized melanoma screening, and can be extended to the screening of other key biomarkers in skin moles. © 2018 WILEY-VCH Verlag GmbH & Co.

    Determine the relative stiffness of 3 bandage/splint constructs intended for emergency fracture stabilization. Experimental model. A single plane free end deflection model was developed to simulate the forces placed on a bandage/splint construct during stabilization of a complete mid-metacarpal bone fracture. The total deflection of the model in one plane was measured following application of 3 different bandage/splint combinations including a classic, 3 layered Robert Jones Bandage (RJB) with a splint placed on the outside of the bandage (RJB-3), an RJB with splint placed after the first of 3 bandage layers (RJB-1), and a single layer full limb bandage with external splint (SS). Comparisons were made between the deflections of the model with each bandage/splint combinations in an effort to determine the most effective method for field fracture stabilization. Laboratory. No animals were utilized in data collection for this study. Two live horses were utilized during the pilot study. Application of bandage and splint to a model intended to simulate the bending force on a lower forelimb fracture in a horse Deflection was determined by the difference between the height of the model's supported free end before application of a 4.5 kg weight and at the conclusion of the deflection test. There was no significant difference in the amount of deflection between bandage/splint combinations (78 ± 32 mm (RJB-1), 94 ± 44 mm (RJB-3), and 93 ± 33 mm (SS)) CONCLUSIONS: The one-layer bandage with splint was equivalent to either RJB configuration in the mean amount of deflection in the simple model of a fracture. © Veterinary Emergency and Critical Care Society 2015.

    Bandage is a medical device that is essential for wound dressing. To improve the performance of the bandage, it has been coated by silver-chitosan nanocomposites (Ag/Chit) with pad-dry-cure method. The nanocomposites were performed by chemical reduction method at room temperature using glucose as reducing agent, sodium hydroxide (NaOH) as accelerator reagent, silver nitrate (AgNO{sub 3}) as metal precursor and chitosan as stabilizing agent. Localized surface plasmon resonance (LSPR) absorption band of silver nanoparticles was investigated using UV-Vis spectrophotometer. The bandage coated Ag/Chit nanocomposites (B-Ag/Chit) were characterized by fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscope (SEM). In addition, antibacterial activity of the bandage toward Gram positive (Staphylococcus aureus) and Gram negative (Escherichia coli) were also studied. The formation of silver nanoparticles was confirmed by the appearance of LSPR absorption peak at 412.2 – 423.2 nm. Coating of nanocomposite cause increasing rigidity of bandage and decreasing on crystallinity. The bandages of B-Ag/Chit demonstrated good activity against both Gram positive (S. aureus) and Gram negative (E.Coli). Thus the bandages have a potential to be used for antibacterial wound dressing application.

    Full Text Available Sportsmen with overhead activities very frequently have an increased mobility of the shoulder joints. Thus it is often difficult to distinguish between stability, hyperlaxity, and instability of the joint. Repeated extreme movements strain static stabilizers and lead to their lengthening. The principal problem in sporters is to establish a balance between the mobility and stability of the shoulder joint. Clinical examinations and the following treatment should be focused not only on pain but also on the stability of the glenohumeral joint. We can encounter a whole range of possibilities from glenohumeral instability to the impingement syndrome. We often find a narrowing of the subacromial space in so-called tennis shoulder (rotation of the scapula and relative abduction of the humerus. A helpful therapeutic solution of this problem should be provided by a bandage of our own new construction. The shoulder bandage consists of an upper arm sleeve and an elastic strap leading across the axilla and fixed around the chest. If the upper extremity is free in adduction, there is no tension to the sleeve but in the moment of abduction, the elastic strap is gradually stretched and the sleeve pulls the proximal humerus down. Greater elevation and greater tension can be modified by the tightening or lengthening of the elastic strap. On the one hand the bandage causes broadening of the subacromial space, on the other hand muscle activity is modified and a higher muscle tonus increasingly stabilizes the joint. This paper describes the effect of the bandage from different points of view – orthopedic, biomechanical, and imaging. A group of 25 patients is evaluated. The feeling of an increased stability of the shoulder is described by 16 sporters and minimizing of pain by using the bandage is reported by 13 sporters. Constraining of locomotion in the edge position is claimed by 18 persons and decreasing of performance resulting from a slowed up lifting of the

    Corneal blindness can occur due to improper healing of the corneal tissues after induced injury or abrasion which can be accidental, pathogenic, or after corneal surgery. Abnormal regulation of the healing mechanisms can lead to corneal opacity. Reducing inflammation and promoting epithelial wound healing are crucial for scar-free corneal recovery without eyesight complications. Current approaches for corneal wound healing involve amniotic membrane (AM) bandages, bandage contact lenses (BCL), and collagen shields in conjunction with frequent administration of therapeutic eye drops. The problem with eye drops is poor bioavailability and patient incompliance that might lead to corneal wound healing complications and poor clinical outcomes. Various methods have been proposed for loading drugs into medicated bandage lenses. There are advantages and limitations associated with each technique regarding the ease of manufacture, drug loading, release kinetics, and suitability with various therapeutics and hydrogel types. There is still, however, no drug-eluting corneal bandage on the market despite the need for such a convenient and cost-efficient strategy for corneal wound healing. This review will highlight materials and therapeutics that can be used in medicated ocular bandages and various ways of incorporating drugs, while discussing the limitations and challenges associated with bringing medicated ocular bandages in the market.

    Elastic bandages are commonly used in sports to treat and prevent sport injuries. To conduct a systematic review assessing the effectiveness of elastic bandaging in orthopedic- and sports-injury prevention and rehabilitation. The researchers searched the electronic databases MEDLINE, CINAHL, SPORTDiscus, EMBASE, and Physiotherapy Evidence Database (PEDro) with keywords elastic bandaging in combination, respectively, with first aid, sports injuries, orthopedic injuries, and sports injuries prevention and rehabilitation. Research studies were selected based on the use of the term elastic bandaging in the abstract. Final selection was made by applying inclusion and exclusion criteria to the full text. Studies were included if they were peer-reviewed clinical trials written in English on the effects of elastic bandaging for orthopedic-injury prevention and rehabilitation. Twelve studies met the criteria and were included in the final analysis. Data collected included number of participants, condition being treated, treatment used, control group, outcome measures, and results. Studies were critically analyzed using the PEDro scale. The studies in this review fell into 2 categories: studies in athletes (n = 2) and nonathletes (n = 10). All included trials had moderate to high quality, scoring ≥5 on the PEDro scale. The PEDro scores for the studies in athletes and nonathletes ranged from 5 to 6 out of 10 and from 5 to 8 out of 10, respectively. The quality of studies was mixed, ranging from higher- to moderate-quality methodological clinical trials. Overall, elastic bandaging can assist proprioceptive function of knee and ankle joint. Because of the moderate methodological quality and insufficient number of clinical trials, further effects of elastic bandaging could not be confirmed.

    The clinical efficacy of electro-therapy in the treatment of chronic wounds is currently debated, and a in-vivo evaluation of stimulation parameters will provide the statistical evidence needed to direct clinical guidelines. A low-cost, wearable electrical stimulation bandage has been developed for use with an established rat ischemic wound model. The bandage consists of a user-programmable stimulator PCB and a plastic bandage with two hydrogel electrodes. The battery-powered bandage may be used for up to seven days between dressing changes, and the stimulator may be reused. The microcontroller-based stimulator uses a boost converter circuit to generate pulses up to 90 V from a 3 V coin cell battery. Consistent operation of the boost converter over the wide input and output voltage ranges is achieved using voltage feedforward and soft-start techniques implemented in firmware. The bandages are laser-cut to shape, and electrical traces are applied using stencils and conductive nickel paint. Both the PCB and electrical traces are encapsulated to protect the animal. The device has been successfully demonstrated using the rat ischemic wound model for a period of seven days, and clinical experiments are ongoing.

    Wound healing is an intricate multistage process that includes inflammation, cell proliferation, matrix deposition and remodeling phases. It is often associated with oxidative stress and consequent prolonged inflammation, resulting in impaired wound healing. Curcumin has been reported to improve wound healing in different animal models. In order to increase the efficacy of curcumin in the healing arena a curcumin loaded oleic acid based polymeric (COP) bandage was formulated. The in vivo wound healing potency was compared with void bandage and control (cotton gauze treatment) in a rat model. Biochemical parameters and histological analysis revealed increased wound reduction and enhanced cell proliferation in COP bandage treated groups due to its efficient free radical scavenging properties. Comparative acceleration in wound healing was due to early implementation of fibroblasts and its differentiation (increased level of α-smooth muscle actin). Western blotting and semiquantitative PCR analysis clearly indicate that COP bandage can efficiently quench free radicals leading to reduced antioxidative enzyme activity. Further evidence at mRNA and protein level indicates that our system is potent enough to reduce the inflammatory response mediated by the NFκB pathway during wound healing. With this background, we anticipate that such a versatile approach may seed new arena for topical wound healing in the near future.

In 13 patients before and 11 patients after liver transplant, the mean (SD) change in leg circumference after a single 8-hour application of an elastic bandage wrap was -2.6 (2.2) cm at the ankle and -3.1 (2.9) cm at midcalf for wrapped legs, as opposed to -0.4 (1.6) cm at the ankle and 1.0 (2.8) cm at midcalf for unwrapped legs (PLeg pain, measured on a visual analog scale, was significantly lower for the wrapped (mean [SD], 10.3 [26.5] mm) versus the unwrapped (20.3 [33.5] mm) leg (P=.04). In inpatients before and after liver transplant, the application of elastic bandage wraps to 1 leg for an 8-hour period led to significantly less edema formation and pain compared with the unwrapped leg. These results support the use of elastic bandage wraps in liver transplant patients to reduce leg edema and improve comfort.

    Chronic wounds, such as venous leg ulcers, can be monitored non-invasively by using modern sensing devices and wireless technologies. The development of such wireless diagnostic tools may improve chronic wound management by providing evidence on efficacy of treatments being provided. In this paper we present a low-power portable telemetric system for wound condition sensing and monitoring. The system aims at measuring and transmitting real-time information of wound-site temperature, sub-bandage pressure and moisture level from within the wound dressing. The system comprises commercially available non-invasive temperature, moisture, and pressure sensors, which are interfaced with a telemetry device on a flexible 0.15 mm thick printed circuit material, making up a lightweight biocompatible sensing device. The real-time data obtained is transmitted wirelessly to a portable receiver which displays the measured values. The performance of the whole telemetric sensing system is validated on a mannequin leg using commercial compression bandages and dressings. A number of trials on a healthy human volunteer are performed where treatment conditions were emulated using various compression bandage configurations. A reliable and repeatable performance of the system is achieved under compression bandage and with minimal discomfort to the volunteer. The system is capable of reporting instantaneous changes in bandage pressure, moisture level and local temperature at wound site with average measurement resolutions of 0.5 mmHg, 3.0 %RH, and 0.2 °C respectively. Effective range of data transmission is 4-5 m in an open environment.

    Internal stress in a compression bandage wrapped over a limb in vitro is expected to reduce over time because of fatigue which may occur due to repetitive and prolonged variations in the extension of the bandage during posture change and exercise. This phenomenon may cause significant variation in the sub-bandage pressure over time. To examine the effect of composition and construction of material on the sub-bandage pressure variation over time in the dynamic state of a limb in the laboratory. Yarns comprising fibers of polyester, viscose, cotton and elastomeric yarn were used to prepare different knitted bandage samples having varying thread densities in the structure. A leg-segment prototype was used for the measurement of the interface pressure over a mannequin limb to analyse different bandages under similar dynamic conditions. The pressure drop in the dynamic state of the mannequin limb was greater than that in the static state. The mean pressure drop in 2 h in the dynamic state was greater by >30% for bandages made of pure cotton or viscose yarns than for bandages having elastomeric yarns in their structure. At the same applied tension, increasing the number of yarns per unit length in the bandage structure resulted in a smaller drop in pressure in the dynamic mode. Elastomeric yarn improves the elasticity and fatigue resistance of the bandage. Therefore, these yarns should be used in bandages to obtain sustained compression effects under dynamic conditions.

    Full Text Available Introduction: Venous leg ulcer is a major health problem in terms of high prevalence and high cost for treatment. Multi-layer compression bandage systems for venous leg ulcers are supposed to be the gold standard for the treatment of venous ulcers. The aim of the current study is to investigate the effectiveness of multi-layer compression bandage systems for the treatment of venous leg ulcers.Patients and Methods: Nineteen consecutive patients diagnosed to have leg ulcers were evaluated and four patients were excluded from the study due to the peripheral arterial disease. Fifteen patients, enrolled in the study, were classified according to CEAP classification and belonged to the same class. Betaven® multi-layer compression bandage was applied to patients. Patients were followed-up in terms of wound healing and reduction in wound diameter.Results: Twelve male and three female patients underwent multi-layer bandage system. Mean age of patients was 38.2 ± 4.2 years. Ulcer size was measured planimetrically and baseline ulcer size was 4-10 cm². The location of ulcer was on medial malloelus in seven patients, lateral malleolus in three patients, anterior surface of the leg in four patients and lateral side of the leg in one patient. Patients had chronic venous insuuficiency for a mean of 5.1 ± 2.1 years. CEAP classifications were C6, Ep, As2,3-p18, Pr2,3, 18. Each bandage was changed five days after application along with wound care. Mean duration of treatment was 6 ± 2 weeks. Complete healing of the venous ulcers occurred in all patients except for one. This patient was referred to plastic surgery clinic for reconstruction.Conclusion: Multi-layer compression bandage system is an effective method of treatment for venous leg ulcers associated with chronic venous insufficiency by reducing venous return and increasing intertitial tissue pressure. This effect occurred in the shortrun as well as with a low cost and prevented loss of labor.

    The purpose of this study is to compare the treatment and retention effects between standard decongestive lymphatic therapy (DLT) combined with pneumatic compression (PC) and modified DLT, in which the use of a short-stretch bandage is replaced with the use of Kinesio tape (K-tape) combined with PC. Forty-one patients with unilateral breast-cancer-related lymphedema for at least 3 months were randomly grouped into the DLT group (bandage group, N = 21) or the modified DLT group (K-tape group, N = 20). Skin care, 30-min manual lymphatic drainage, 1-h pneumatic compression therapy, application of a short-stretch bandage or K-tape for each group, and a 20-min physical therapy exercise were given during every treatment session. Patient evaluation items included physical therapy assessment, limb size, water composition of the upper extremity, lymphedema-related symptoms, quality of life, and patients' acceptance to the bandage or tape. There was no significant difference between groups in all outcome variables (P > 0.05) through the whole study period. Excess limb size (circumference and water displacement) and excess water composition were reduced significantly in the bandage group; excess circumference and excess water composition were reduced significantly in the tape group. The acceptance of K-tape was better than the bandage, and benefits included longer wearing time, less difficulty in usage, and increased comfort and convenience (P tape could replace the bandage in DLT, and it could be an alternative choice for the breast-cancer-related lymphedema patient with poor short-stretch bandage compliance after 1-month intervention. If the intervention period was prolonged, we might get different conclusion. Moreover, these two treatment protocols are inefficient and cost time in application. More efficient treatment protocol is needed for clinical practice.

    Full Text Available This paper presents the development of an improved mobile-based telemetric dual mode sensing system to monitor pressure and moisture levels in compression bandages and dressings used for chronic wound management. The system is fabricated on a 0.2 mm thick flexible printed circuit material, and is capable of sensing pressure and moisture at two locations simultaneously within a compression bandage and wound dressing. The sensors are calibrated to sense both parameters accurately, and the data are then transmitted wirelessly to a receiver connected to a mobile device. An error-correction algorithm is developed to compensate the degradation in measurement quality due to battery power drop over time. An Android application is also implemented to automatically receive, process, and display the sensed wound parameters. The performance of the sensing system is first validated on a mannequin limb using a compression bandage and wound dressings, and then tested on a healthy volunteer to acquire real-time performance parameters. The results obtained here suggest that this dual mode sensor can perform reliably when placed on a human limb.

    Full Text Available Objectives. The aim of the study was to investigate the effect of balance training with Nintendo Wii technology, with and without the use of additional sensory information (subpatellar bandage, in the functional mobility and gait speed of elderly female fallers. Methods. Twenty elderly women were divided into two groups: group I: trained with the use of the Nintendo Wii; group II: trained using the Nintendo Wii and the addition of sensory information (subpatellar bandage. The functional mobility was assessed with the Timed up and Go test (TUG and gait speed with the 10 m test. The tests were carried out with and without the use of the subpatellar bandage. The training was carried out within sessions of 30 minutes, twice a week, using three different games (Penguin Slide, Table Tilt, and Tightrope. Results. There was an increase in the gait speed and a decrease in the TUG time in both groups, independently of the sensory condition used (p<0.05. In the short term, the subpatellar bandage improved the TUG time (p<0.05 and the gait speed (p<0.01. Conclusion. The training for postural balance with virtual reality was effective for improving functional mobility and gait speed of elderly female fallers. The subpatellar bandage did not maximize the effect of training.

    Radiation therapy is used as a primary treatment for inoperable tumors and in patients that cannot or will not undergo surgery. Radioactive holmium-166 ((166)Ho) is a viable candidate for use against skin cancer. Nonradioactive holmium-165 ((165)Ho) iron garnet nanoparticles have been incorporated into a bandage, which, after neutron-activation to (166)Ho, can be applied to a tumor lesion. The (165)Ho iron garnet nanoparticles ((165)HoIG) were synthesized and introduced into polyacrylonitrile (PAN) polymer solutions. The polymer solutions were then electrospun to produce flexible nonwoven bandages, which are stable to neutron-activation. The fiber mats were characterized using scanning electron microscopy, transmission electron microscopy, powder X-ray diffraction, Fourier transform infrared spectroscopy, thermogravimetric analysis and inductively coupled plasma mass spectrometry. The bandages are stable after neutron-activation at a thermal neutron-flux of approximately 3.5 × 10(12) neutrons/cm(2)·s for at least 4 h and 100 °C. Different amounts of radioactivity can be produced by changing the amount of the (165)HoIG nanoparticles inside the bandage and the duration of neutron-activation, which is important for different stages of skin cancer. Furthermore, the radioactive bandage can be easily manipulated to irradiate only the tumor site by cutting the bandage into specific shapes and sizes that cover the tumor prior to neutron-activation. Thus, exposure of healthy cells to high energy β-particles can be avoided. Moreover, there is no leakage of radioactive material after neutron activation, which is critical for safe handling by healthcare professionals treating skin cancer patients.

    Ocular trauma and disorders that lead to corneal blindness account for over 2 million new cases of monocular blindness every year. A popular ocular surface reconstruction therapy, amniotic membrane transplantation, has been shown to aid corneal wound repair. However, the success rates of the procedure are variable. Here, we proposed to bioengineer a novel synthetic material that would serve as a biomimetic corneal bandage. The PLGA-PEG-PLGA triblock copolymer was synthesised via ring-opening polymerisation. Thermoreversible gelation behaviour was investigated at different polymer concentrations (23%, 30%, 35%, 40%, 45%, w/v) at temperatures ranging between 5 and 60 degrees C. Viscoelastic properties were studied in dynamic mechanical analysis with 1 degrees C/min temperature ramp. Cryo-SEM revealed a porous hydrogel with interconnecting networks. No adverse cytotoxicity was observed with an in vitro scratch-wound assay and in in vivo biocompatibility tests. We have demonstrated that the PLGA-PEG-PLGA hydrogel possessed a suitable gelling profile and, for the first time, the biocompatibility properties for this application as a potential bandage for corneal wound repair.

    This observational study was designed to analyze the safety and feasibility of percutaneous skin closure using a purse-string suture and compare it with the use of a compression bandage after pulmonary vein isolation. A total of 407 patients undergoing pulmonary vein isolation (217 with radiofrequency and 190 with cryoballoon ablation) were treated with either purse-string sutures or compression bandages. The purse-string suture was applied after ablation before withdrawal of the sheaths. Patients were on bed rest for 6 hours prior to suture removal, which was accomplished 18-24 h after ablation. The compression bandage was applied after sheath withdrawal and was removed after 12 hours of bed rest. We analyzed the occurrence of any vascular or thromboembolic complication as well as hospital costs and hospital stay length after ablation. The incidence of vascular complications after compression bandage was higher than after purse-string suture in the cryoballoon and radiofrequency group (P string suture. Percutaneous skin closure with a purse-string suture has the clinical impact to reduce vascular complications, hospital costs, and hospital stay length after pulmonary vein isolation. © 2017 Wiley Periodicals, Inc.

    Full Text Available Objective: to investigate whether a neoprene sleeve and elastic bandage around the knee joint of subjects with knee osteoarthritis (OA would , in short term (a reduce pain (b improve knee joint position sense and comparison of their effect with each other if they have. Materials & Methods: In a semi-experimental study, 30 subjects (11 men, 19 women, age between 33-75 with unilateral knee OA. Subjects had to have at least 2cm from 10cm visual analogue scale (VAS of knee pain for study entry.All patients were randomly assigned to either an elastic bandage or a neoprene sleeve. One week later they were assigned to the opposite selection. Joint position sense was assessed in the sitting position using an electrogoniometer and pain by VAS where 0cm equals no pain and 10 cm equals worst pain. Knee pain and JPS were assessed for each selection one week apart. During each visit assessment were performed at baseline and after 20 min of bandage/neoprene sleeve application. Results: the mean of scores for knee variables JPS and VAS was taken and paired-t test and Wilcoxon signed rank test was employed to calculate the different between two trails. Neoprene sleeve had significant effect on knee JPS (P=0.037. But elastic bandage had no effect (P=0.631. Both of them had significantly reduced knee pain. (P=0.000 Conclusion: In subjects with both neoprene sleeve and elastic bandage reduced knee pain with more effect of neoprene sleeve. Only the neoprene sleeve had effect on knee JPS.

    Oxygen plays an important role in wound healing, as it is essential to biological functions such as cell proliferation, immune responses and collagen synthesis. Poor oxygenation is directly associated with the development of chronic ischemic wounds, which affect more than 6 million people each year in the United States alone at an estimated cost of $25 billion. Knowledge of oxygenation status is also important in the management of burns and skin grafts, as well as in a wide range of skin conditions. Despite the importance of the clinical determination of tissue oxygenation, there is a lack of rapid, user-friendly and quantitative diagnostic tools that allow for non-disruptive, continuous monitoring of oxygen content across large areas of skin and wounds to guide care and therapeutic decisions. In this work, we describe a sensitive, colorimetric, oxygen-sensing paint-on bandage for two-dimensional mapping of tissue oxygenation in skin, burns, and skin grafts. By embedding both an oxygen-sensing porphyrin-dendrimer phosphor and a reference dye in a liquid bandage matrix, we have created a liquid bandage that can be painted onto the skin surface and dries into a thin film that adheres tightly to the skin or wound topology. When captured by a camera-based imaging device, the oxygen-dependent phosphorescence emission of the bandage can be used to quantify and map both the pO2 and oxygen consumption of the underlying tissue. In this proof-of-principle study, we first demonstrate our system on a rat ischemic limb model to show its capabilities in sensing tissue ischemia. It is then tested on both ex vivo and in vivo porcine burn models to monitor the progression of burn injuries. Lastly, the bandage is applied to an in vivo porcine graft model for monitoring the integration of full- and partial-thickness skin grafts.

    Full Text Available AIM: To evaluate the safety of therapeutic bandage contact lens for post-cataract surgery patients and to illustrate its efficacy on post-operative comfort and tear-film stability. METHODS: A total of 40 participants were recruited and randomly divided into two groups. Group one was instructed to wear bandage contact lenses for a week and use antibiotic eye drops for a month since the first day after surgery. Group two received sub-conjunctival injection of tobramycin and was asked to wear eye pads on the first day after surgery and then were instructed to use antibiotic eye drops as the first group did. Ocular surface disease index (OSDI questionnaire, slit-lamp microscope examination of tear break-up time (TBUT, corneal fluorescein score (CFS, tear meniscus height (TMH together with anterior segment optical coherence tomography (AS-OCT and corneal topography were evaluated preoperatively and postoperatively. RESULTS: The subjective feeling (P=0.004, TBUT (P<0.001 and TMH (P=0.02 post-surgery had improved in patients who used bandage contact lenses compared with those who did not at 1wk post-surgery. Until three month postoperatively, the comfort degree (P=0.004 and TMH (P=0.01 of group two were still worse than group one. Moreover, TBUT (P<0.001 and CFS (P=0.004 of the group with eye pads got worse than the results before, whereas the group with bandage contact lenses recovered to normal. None of these patients had infections or other complications. CONCLUSION: Wearing therapeutic bandage contact lens after cataract surgery, compared with traditional eye-pads, is a safe method to improve tear-film stability and reduce post-operative discomfort without hindering corneal incision recovery.

    Full Text Available Background: In general, many patients with acute proximal deep vein thrombosis (DVT are treated with heparin and oral anticoagulant. Many physicians have been taught to admit these patients to absolute bed rest for the first 24-48 hours due to the fear of dislodging clots that may lead to fatal pulmonary embolism (PE. Objective: The aim of this study is to compare the differences among the changing circumference of affected limb, the severity of pain, and the incidence of symptomatic PE in 3 groups of acute proximal DVT, including absolute bed rest with compression bandages (group 1, ambulation with compression bandages (group 2, and ambulation without compression bandages (group 3. Methods: Between January 2006 and March 2011, 60 patients were enrolled in this study. In this analysis, the clinical characteristics, the changes of affected limb circumference and pain score during the first week of admis- sion and the incidence of symptomatic PE among 3 groups of this study were analyzed. Results: There were no statistical differences in the characteristics among 3 groups of patients. The most gender was female and the mean age for 3 groups ranged from 55.1 to 63.7 years. Comparing among 3 groups, it showed a significant difference of calf circumferences between group 1 and group 3. None of pain score differences were statistically significant among 3 groups. In addition, there was no incidence of symptomatic PE in the three groups of the present study. Conclusion: Our findings confirm that acute proximal DVT treatment with ambulation does not increase the incidence of symptomatic PE, compared with absolute bed rest. Although there is no statistical decrease of the severity of pain between those 3 groups, the group of absolute bed rest and compression can promote the resolution of calf swelling, compared with the group of ambulation without compression bandages.

    Multi-drug resistant Pseudomonas aeruginosa has increased progressively and impedes further regression in mortality in burn patients. Such wound infections serve as bacterial reservoir for nosocomial infections and are associated with significant morbidity and costs. Anti-microbial polycationic dendrimers G3KL and G3RL, able to kill multi-drug resistant P. aeruginosa, have been previously developed. The combination of these dendrimers with a class of biological bandages made of progenitor skin cells, which secrete growth factors, could positively impact wound-healing processes. However, polycations are known to be used as anti-angiogenic agents for tumor suppression. Since, neovascularization is pivotal in the healing of deep burn-wounds, the use of anti-microbial dendrimers may thus hinder the healing processes. Surprisingly, we have seen in this study that G3KL and G3RL dendrimers can have angiogenic effects. Moreover, we have shown that a dendrimer concentration ranging between 50 and 100 μg/mL in combination with the biological bandages can suppress bacterial growth without altering cell viability up to 5 days. These results show that antimicrobial dendrimers can be used in combination with biological bandages and could potentially improve the healing process with an enhanced angiogenesis.

    Full Text Available In the current work, a new antibacterial bandage was proposed where diamond-like carbon with silver nanoparticle (DLC:Ag-coated synthetic silk tissue was used as a building block. The DLC:Ag structure, the dimensions of nanoparticles, the silver concentration and the silver ion release were studied systematically employing scanning electron microscopy, energy dispersive X-ray spectroscopy and atomic absorption spectroscopy, respectively. Antimicrobial properties were investigated using microbiological tests (disk diffusion method and spread-plate technique. The DLC:Ag layer was stabilized on the surface of the bandage using a thin layer of medical grade gelatin and cellulose. Four different strains of Staphylococcus aureus extracted from humans’ and animals’ infected wounds were used. It is demonstrated that the efficiency of the Ag+ ion release to the aqueous media can be increased by further RF oxygen plasma etching of the nanocomposite. It was obtained that the best antibacterial properties were demonstrated by the plasma-processed DLC:Ag layer having a 3.12 at % Ag surface concentration with the dominating linear dimensions of nanoparticles being 23.7 nm. An extra protective layer made from cellulose and gelatin with agar contributed to the accumulation and efficient release of silver ions to the aqueous media, increasing bandage antimicrobial efficiency up to 50% as compared to the single DLC:Ag layer on textile.

    Full Text Available Aim: To assess the physical and mechanical properties of plaster of Paris (POP bandage cast used as a splinting and casting materials. Materials and Methods: POP casts were divided into three Groups A, B and C with 2, 3 and 8 layer for POP bandage, respectively (n=6 in each group. Handling characters, technical easiness or difficulties, setting time, weight, diameter and thickness of the casts were recorded for different groups. The casts were mounted on universal testing machine and axial load was applied @ 10 mm/min until failure. The load deflection graphs were plotted. The maximum force at which failure of the casts occurred was recorded. Stress, strain, modulus of elasticity (MOE and stiffness of casts were calculated. Result: Construction of POP bandage cast was messy and required 45-60 min for hardening. 8 layer POP cast was comparatively heavier in weight and thicker in cross section than 3 layer cast followed by 2 layer cast. Under axial compression, the load bearing capacity of 8 layer POP casts was more than 2 and 3 layer cast. Conclusion: The values of load bearing capacity, stress, stiffness and MOE of cast were the highest for 8 layer POP cast followed by 2 and 3 layer cast. Use if splints with POP cast is recommended due to its poor mechanical properties.

    Disorders associated with the lower extremity venous system are common and significantly affect the quality of life of a large number of individuals. These disorders include orthostatic hypotension, oedema, deep vein thrombosis and a number of other conditions related to insufficient venous blood return. The common recommended treatment for these disorders is the use of hosiery compression stockings. In this research, an active compression bandage (ACB) based on the technology of dielectric elastomeric actuators (DEA) was designed, prototyped and tested. A customized calf prototype (CP) was developed to measure the pressure applied by the ACB. Experimental results performed with the CP showed that the pressure applied by the ACB could be electrically controlled to be either below or above the pressure exerted by commercially available compression stockings. An analytical model was used to provide the design criteria. A finite element model (FEM) was also developed to simulate the electromechanical behaviour of the DEA. Comparison of the experimental results with the FEM and analytical models showed that the modelling could accurately predict the behaviour of the ACB. The FEM was subsequently used to study how to improve the ACB performance by varying geometrical parameters such as the ACB thickness.

    To evaluate and compare Comfilcon A and Senofilcon A silicone hydrogel contact lenses used as a therapeutic bandage following transepithelial excimer laser photorefractive keratectomy (PRK). Patients undergoing transepithelial PRK for myopia were prospectively recruited. Included patients had a Comfilcon A silicone hydrogel lens inserted in one eye, with a Senofilcon A lens in the contralateral eye. Postoperative assessment of subjective pain, epithelial healing and visual recovery was at day 1, 3 and 7. Contact lens factors including centration, movement and deposits were assessed. 48 eyes of 24 patients were included in the study. Mean age was 31 years (SD 11) and mean refractive error -4.5 D (SD 1.8). Mean pain score at day 1 was significantly higher in the Comfilcon group at 4.6 (SD 2.7) vs. 1.5 (SD2.5) in the Senofilcon group (P<0.005). Mean time to healing was 3.17 days (SD 0.37) in the Comfilcon group, and 3.21 days (SD 0.4) in the Senofilcon group, with no difference in defect size. There was a pronounced central raphe in 1 eye in the Comfilcon group vs. 5 eyes in the Senofilcon group (P=0.19). Significantly more eyes demonstrated no lens movement in the Senofilcon group (18 vs. 4, P=0.0001). The variation in material characteristics and lens geometry of different silicone hydrogel lenses affects their clinical characteristics in therapeutic roles. Other factors than oxygen permeability may affect pain and epithelial healing, with superior pain relief from the less permeable Senofilcon lens in this study.

    Secondary lymphedema (SL) following breast cancer is a well-known complication following surgery or radiation. SL may result in loss of functional ability, cosmetic deformities, physical discomfort, recurrent episodes of erysipelas, and psychological distress. There is no evidence as to what is the most effective treatment for SL. This randomized controlled pilot study included 10 patients treated for SL following breast cancer. The patients were included and screened for SL by a physiotherapist. They were randomized to treatment with CDP with Kinesio Textape or bandage for 4 weeks. Endpoints were quality of life, circumference of the arm, costs, and working environment for the physiotherapist. The two groups were comparable according to baseline data. Outcomes on quality of life, costs, and working environment for the physiotherapist; the treatment with CDP with tape was superior to the CDP with bandage treatment. In regard to reducing the circumference there was no difference. This randomized controlled pilot study shows that CDP with tape can be an alternative to CDP with bandage. The quality of life is higher, the economy and working environment is better, and the effect measured by circumference is comparable. More RCTs are required to increase the evidence for CDP with tape. Treating lymphedema with CDP with tape after breast cancer is a good alternative to CDP with bandage and makes it possible to treat more patients with less resources.

    Little evidence exists evaluating the possible effect of dressings on the recovery of function, sensation and joint motion following a hand burn. Hand burns are traditionally covered by a layer of non-adherent dressing followed by gauze and bandages. However, there is no evidence for the efficacy of this type of coverage relative to a functional recovery. The Gore-tex bag has a small body of research supporting its ability to provide a superior healing atmosphere, however there is no literature directly comparing it with the traditional dressing. A randomised cross-over design was implemented to compare Gore-tex bags and traditional dressings in 30 healthy volunteers. Seven outcome measures of function, sensation, joint range of movement and subject perceptions were recorded before dressing, during both Gore-tex and traditional dressing interventions and between dressings. Statistically significant differences were found between the traditional dressings and Gore-tex bags. The Gore-tex bag dressings proved better for digit range of motion, 1st CMC joint motion and sensation. The traditional dressings were significantly better when perceived comfort was tested and there was no significant difference between the traditional dressing and Gore-tex bag regarding function and perceived function. The results of this study suggest that traditional dressings may detrimentally affect movement and reduce sensation but not necessarily affect function or comfort. Further investigation in a patient cohort with burnt hands is recommended.

    [Purpose] The aim of this study was to evaluate the effects of proprioceptive neuromuscular facilitation (PNF) D2 flexion and breathing exercises in a patient with lymphedema (LE). [Subject] This report describes a 57-year-old woman with LE in whom a short-stretch compression bandage (SSCB) could not be used for treatment because of skin itching and redness. [Methods] The patient received complex decongestive therapy without a SSCB. Next, PNF D2 flexion and breathing exercises were conducted three times per week for 14 weeks (36 times). [Results] As a result, the circumference of the armpit was reduced by 0.5 cm; that of 10 cm above the elbow, by 1 cm; that of the elbow, by 0.5 cm; that of 10 cm below the elbow, by 1 cm; and that of the back of the hand, by 0.5 cm. A total of 100 mL (9.4%) of body water was eliminated from the right upper extremity, and moisture ratio was reduced by 0.005%. Finally, range of motion was improved to 20° flexion, 60° abduction, 40° external rotation, and 10° internal rotation. [Conclusion] This study showed that PNF D2 flexion and breathing exercises were effective in reducing LE and improving range of motion.

    Drawbacks exist with the standard treatment (four-layer compression bandages) for venous leg ulcers. We have therefore compared the clinical effectiveness and cost-effectiveness of two-layer compression hosiery with the four-layer bandage for the treatment of such ulcers. We undertook this pragmatic, open, randomised controlled trial with two parallel groups in 34 centres in England and Northern Ireland. The centres were community nurse teams or services, family doctor practices, leg ulcer clinics, tissue viability clinics or services, and wound clinics. Participants were aged 18 years or older with a venous leg ulcer and an ankle brachial pressure index of at least 0·8, and were tolerant of high compression. We randomly allocated participants (1:1) to receive two-layer compression hosiery or a four-layer bandage, using a remote randomisation service and prevalidated computer randomisation program. Participants were stratified by ulcer duration and ulcer area with permuted blocks (block sizes four and six). The primary endpoint was time to ulcer healing, with a maximum follow-up of 12 months. Although participants and health-care providers were not masked to treatment allocation, the primary endpoint was measured by masked assessment of photographs. Primary analysis was intention to treat with Cox regression, with adjustment for ulcer area, ulcer duration, physical mobility, and centre. This trial is registered with the ISRCTN register, number ISRCTN49373072. We randomly allocated 457 participants to the two treatment groups: 230 to two-layer hosiery and 227 to the four-layer bandage, of whom 453 (230 hosiery and 223 bandage) contributed data for analysis. Median time to ulcer healing was 99 days (95% CI 84-126) in the hosiery group and 98 days (85-112) in the bandage group, and the proportion of ulcers healing was much the same in the two groups (70·9% hosiery and 70·4% bandage). More hosiery participants changed their allocated treatment (38·3% hosiery vs 27

    Although plate fixation has advantages over other fixation methods for certain indications, it is rarely used in avian surgery, especially in birds that weigh less than 1000 g. Exceptionally small plating systems for these birds are required, which are relatively expensive and difficult to insert. To study avian fracture healing after repair using miniplates, we evaluated 2 steel miniplate systems in 27 pigeons ( Columba livia ) divided into 4 groups. In each pigeon, the left ulna and radius were transected and the ulna was repaired with a bone plate. In groups A and B, a 1.3-mm adaption plate was applied without and with a figure-of-eight bandage; in groups C and D, a 1.0-mm compression plate was applied without and with a bandage, respectively. Healing was evaluated with radiographs after 3, 14, and 28 days; flight tests were conducted after 14, 21, and 28 days; and the wing was macroscopically examined after euthanasia of birds on day 28. Fractures healed without bending or distortion of the plate in all 27 birds, and no significant differences in healing were found between treatment groups. At the end of the study, 23 pigeons (85.2%) showed good or very good flight ability. Results show the 1.3-mm adaption plate and the 1.0-mm compression plate meet the requirements for avian osteosynthesis and can be recommended for fracture repair of the ulna or other long bones in birds weighing less than 500 g. The application of a figure-of-eight bandage might be beneficial in fracture healing.

    Multiple topical hemostats have been approved for control of surface bleeding from vascular access sites. The majority of these devices, however, have few clinical data supporting their use. This study was conducted to assess the efficacy and safety of the new commercially available D-Stat Dry hemostatic bandage compared to standard care manual compression. A prospective, randomized, multicenter trial was conducted in patients undergoing diagnostic cardiac catheterization or peripheral angiography utilizing femoral artery access. Subjects were randomized to either the D-Stat Dry bandage as an adjunct to manual compression or manual compression alone. Primary end points were time-to-hemostasis (TTH) and major complications. Secondary end points included minor complications, patient satisfaction, time-to-ambulation (TTA), and time-to-discharge (TTD). Three hundred seventy-six subjects (189 control, 187 investigational) with similar baseline characteristics participated in the study. The mean age was 61.5 years, with a male predominance of 58%. TTH was significantly lower in the investigational group (7.8 vs. 13.0 min; p = 0.001). No difference in major complication rates was observed between the groups. The mean TTA (investigational, 392 min, vs. control, 415 min; p = 0.023) and patient satisfaction significantly favored the investigational group (p = 0.025). No difference in TTD or the rate of minor complications was observed. This study demonstrates that in the aforementioned population, the D-Stat Dry bandage is safe and effective in reducing both TTH and TTA and results in improved patient satisfaction

    To evaluate negative pressure wound therapy (NPWT) for treatment of complicated wounds in dogs. Retrospective multicentre study. Dogs (n = 50) undergoing open wound treatment were classified according to treatment method used: bandage (Group A, n = 7), NPWT (Group B, n = 18), and foam dressing (Group C, n = 25). Pairs of patients matched based on wound conformation, localization, and underlying cause were compared between Group A and C (n = 7 pairs) and between groups B and C (n = 18 pairs) in terms of duration of previous treatment, time to closure, and complications. Signalment, antibiotic medications, antiseptic treatment, and bacterial status of wounds were comparable between groups. The duration of previous treatment was significantly higher in patients assigned to Group B (p = 0.04) compared to Group C, while no significant difference was found between groups A and B. Total time to wound closure was significantly shorter in Group C compared to Group A (p = 0.02) and in Group B compared to Group C (p = 0.003). Wounds treated with NPWT suffered significantly less complications (p = 0.008) and were significantly less septic during treatment (p = 0.016) than wounds treated with a foam dressing. This study shows that time to healing was halved in NPWT treated patients compared to foam dressing treated patients, which in turn healed faster than patients treated with conventional bandage, underlining the value of NPWT therapy for the treatment of complicated wounds.

    OBJECTIVE To determine the effects of 3 topically applied treatments (1% silver sulfadiazine cream [SSC], triple antimicrobial ointment [TAO], and hyperosmolar nanoemulsion [HNE]) on microbial counts, exuberant granulation tissue (EGT) development, and reepithelialization of contaminated wounds at the distal aspect of the limbs of horses. ANIMALS 8 healthy adult horses. PROCEDURES A 2.5 × 2.5-cm, full-thickness, cutaneous wound was created at the dorsal aspect of each metacarpus and metatarsus (1 wound/limb/horse), covered with nonadhesive dressing, and bandaged. Wounds were inoculated with bacteria and fungi the next day. Each wound on a given horse was randomly assigned to 1 of 4 treatment groups (SSC, TAO, HNE, or no topical treatment [control]). Bandage changes, culture of wound samples, treatments, photography for wound measurements, and biopsy were performed at predetermined time points. Time (days) until wound closure, number of EGT excisions, microbial counts, and scores for selected histologic characteristics were compared among groups. RESULTS Median time to wound closure for all groups was 42 days. Time to wound closure and histologic characteristics of wound healing did not differ among groups. Least squares mean microbial counts were significantly higher for HNE-treated wounds on days 9 and 21, compared with SSC-treated and TAO-treated wounds, but not controls. Proportions of SSC-treated (7/8) or HNE-treated (5/8) wounds needing EGT excision were significantly greater than that of TAO-treated (1/8) wounds. The proportion of SSC-treated wounds with EGT excision was greater than that of controls (3/8). CONCLUSIONS AND CLINICAL RELEVANCE None of the treatments resulted in more rapid wound closure, compared with that for untreated control wounds under the study conditions. When treatment is warranted, TAO may help to limit EGT formation.

    Full Text Available Realizou-se a ceratectomia superficial em 28 coelhos, distribuídos em dois grupos. No grupo tratado, composto por 14 animais, utilizou-se a membrana amniótica canina como bandagem, suturada com sua face epitelial voltada contra a superfície corneana. O grupo controle não recebeu tratamento. A avaliação clínica foi realizada 24 horas após a cirurgia, a cada dois dias durante uma semana e a cada quatro dias até 180 dias. Avaliaram-se os efeitos da membrana amniótica como bandagem, comparando-se o tempo de epitelização da córnea entre os grupos e verificando o período necessário para que a córnea apresentasse transparência completa. A opacidade corneana esteve presente em todos os animais durante o período observado. O tratamento instituído resultou clinicamente em neovascularização corneana, opacidade de córnea mais intensa no período inicial de reparação, retardou o processo de epitelização e causou mais dor e desconforto que nos animais do grupo-controle.Twenty-eight rabbits were submitted to superficial keratectomy. The treated group consisted of 14 animals received canine amniotic membrane as a bandage, sutured in a way that its epithelial surface was in contact with the corneal surface. The control group did not receive any treatment. The animals were submitted to clinical evaluations 24 hours after surgery, at each two-day interval during one week and at each four-day interval during 180 days. The amniotic membranes were evaluated as a bandage comparing the time needed for corneal epithelization in the treated and non-treated groups and determining the period necessary for the cornea to become completely transparent. The corneal opacity was present during the entire time of observation. The treated animals presented more opaque cornea in the early period of regeneration, with neovascularization and more pain and discomfort than the animals from control group, showing a delayed epithelization.

    Compression is an effective and recommended treatment for venous leg ulcers. Although the four-layer bandage (4LB) is regarded as the gold standard compression system, it is recognised that the amount of compression delivered might be compromised by poor application technique. Also the bulky nature of the bandages might reduce ankle or leg mobility and make the wearing of shoes difficult. Two-layer compression hosiery systems are now available for the treatment of venous leg ulcers. Two-layer hosiery (HH) may be advantageous, as it has reduced bulk, which might enhance ankle or leg mobility and patient adherence. Some patients can also remove and reapply two-layer hosiery, which may encourage self-management and could reduce costs. However, little robust evidence exists about the effectiveness of two-layer hosiery for ulcer healing and no previous trials have compared two-layer hosiery delivering 'high' compression with the 4LB.

    Terahertz electromagnetic waves have long been proposed to be ideal for spectroscopy and imaging through non-polar dielectric materials that contain no water. Terahertz radiation may thus be useful for monitoring burn and wound injury recovery, as common care treatments involve application of both a clinical dressing and topical ointment. Here, we investigate the optical properties of typical care treatments in the millimeter wave (150–300 GHz), terahertz (0.3–3 THz), and infrared (14.5–0.67 μm) ranges of the electromagnetic spectrum. We find that THz radiation realizes low absorption coefficients and high levels of transmission compared to infrared wavelengths, which were strongly attenuated. Terahertz imaging can enable safe, non-ionizing, noninvasive monitoring of the healing process directly through clinical dressings and recovery ointments, minimizing the frequency of dressing changes and thus increasing the rate of the healing process.

    To investigate the agents of bacterial contamination of contact lenses after corneal collagen cross-linking (CCL), and to present the possible changes of ocular flora after riboflavin/ultraviolet A. Seventy-two contact lenses of patients who underwent CCL and 41 contact lenses of patients who underwent photorefractive keratectomy (PRK) as control group were enrolled to the study. After 48 h of incubation, broth culture media was transferred to plates. Samples were accepted as positive if one or more colony-forming units were shown. There were positive cultures in 12 (16.7%) contact lenses in the CCL group and 5 (12.2%) had positive cultures in PRK group. Coagulase-negative staphlycocci (CNS) were the most frequent microorganism. Alpha hemolytic streptococci and Diphteroid spp. were the other isolated microorganisms. Bacterial colonization can occur during and early after the CCL procedure in epithelial healing. To prevent corneal infections after the treatment, prophylactic antibiotics should be prescribed.

    To assess the effect of two silicone hydrogel contact lenses with high oxygen permeability in patients having photorefractive keratectomy (PRK). Farabi Eye Hospital, Tehran University of Medical Sciences, Tehran, Iran. Sixty patients (120 eyes) who had bilateral PRK were enrolled in this double blind clinical trial. Each patient was fitted with a Lotrafilcon B (Air Optix(®)AQUA, Ciba Vision, Duluth, GA, USA) lens in one eye and a Balafilcon A (PureVision™ Bausch & Lomb, Rochester, NY, USA) lens in the fellow eye. Patients' responses to a subjective questionnaire in terms of pain, foreign body sensation, photophobia, blurred vision and epiphora were evaluated on the first and third postoperative days. Mean pain score for Lotrafilcon B and Balafilcon A contact lenses was 4.43±3.18 vs. 5.45±3.37 on the first postoperative day and 3.43±3.23 vs. 3.88±3.01 on the third postoperative day. However, the difference was only significant in the first 24h after surgery (P=0.032). Foreign body sensation was clinically higher with Balafilcon A contact lens (5.0±3.47 vs. 4.08±3.34 on day 1 and 4.98±3.52 vs. 3.55±3.20 on day 3) and the difference was statistically significant on the first and the third postoperative days (P=0.042 and 0.002, respectively). There was no statistically significant difference between two contact lenses in terms of photophobia, epiphora and blurred vision (P>0.05). The Lotrafilcon B lens resulted in significantly less postoperative pain and discomfort after PRK, especially in the first 24h after PRK. Copyright © 2015. Published by Elsevier Ltd.

    Cellulose is a biologically derived material with excellent wound-healing properties. The high strength of cellulose fibers and the ability to synthesize gels with high optical transparency make these materials suitable for ocular applications. In this study, cellulose materials derived from wood pulp, cotton, and bacterial sources were dissolved in lithium chloride/N,N-dimethylacetamide to form regenerated cellulose hydrogels. Material properties of the resulting hydrogels, including water content, optical transparency, and tensile and tear strengths, were evaluated. Synthesis parameters, including activation time, dissolution time, relative humidity, and cellulose concentration, were found to impact the material properties of the resulting hydrogels. Overnight activation time improves the optical transparency of the hydrogels from 77% to 97% at 550 nm, whereas controlling cellulose concentration improves their tear strength by as much as 200%. On the basis of the measured transmittance and strength values of the regenerated hydrogels prepared via the optimized synthesis parameters, Avicel PH 101, Sigma-Aldrich microcrystalline cellulose 435236, and bacterial cellulose types were prioritized for future biocompatibility testing and potential clinical investigation. - Highlights: • Hydrogels were prepared (via LiCl/DMAc) from 7 different types of cellulose. • Synthesis parameters (activation, gelation, and concentration) were optimized. • Impact of synthesis parameters on transparency and strength was explored

    In humans, biofilm is a well-known cause of delayed healing and low-grade inflammation of chronic wounds. In horses, biofilm formation in wounds has been studied to a very limited degree. The objective of this study was thus to investigate the occurrence of biofilm in equine experimental wounds healing by secondary intention. Tissue biopsies from non-contaminated, experimental excisional shoulder and limb wounds were obtained on day 1-2, day 7-10 and day 14-15 post-wounding. Limb wounds were either un-bandaged or bandaged to induce exuberant granulation tissue (EGT) formation and thereby impaired healing. Presence of biofilm in tissue biopsies was assessed by peptide nucleic acid fluorescence in situ hybridization (PNA FISH) and confocal laser scanning microscopy (CLSM). Bandaged limb wounds developed EGT and displayed delayed healing, while shoulder and un-bandaged limb wounds healed normally. Biofilm was detected in limb wounds only. At day 14-15 biofilm was significantly more prevalent in bandaged limb wounds than in un-bandaged limb wounds (P=0.003). Further, bandaged limb wounds had a statistically significant increase in biofilm burden from day 7-10 to day 14-15 (P=0.009). The finding that biofilm was most prevalent in bandaged limb wounds with EGT formation suggests that biofilm may be linked to delayed wound healing in horses, as has been observed in humans. The inability to clear bacteria could be related to hypoxia and low-grade inflammation in the EGT, but the interaction between biofilm forming bacteria and wound healing in horses needs further elucidation.

    Fractures of the humerus have challenged medical practitioners since the beginning of recorded medical history. In the earliest known surgical text, The Edwin Smith Papyrus (copied circa 1600 BC), three cases of humeral fractures were described. Reduction by traction followed by bandaging with linen was recommended. In Corpus Hippocraticum (circa 440-340 BC), the maneuver of reduction was fully described: bandages of linen soaked in cerate and oil were applied followed by splinting after a week. In The Alexandrian School of Medicine (third century BC), shoulder dislocations complicated with fractures of the humerus were mentioned and the author discussed whether the dislocation should be reduced before or after the fracture. Celsus (25 BC-AD 50) distinguished shaft fractures from proximal and distal humeral fractures. He described different fracture patterns, including transverse, oblique, and multifragmented fractures. In Late Antiquity, complications from powerful traction or tight bandaging were described by Paul of Aegina (circa AD 625-690). Illustrations from sixteenth and seventeenth century surgical texts are included to show the ancient methods of reduction and bandaging. The richness of written sources points toward a multifaceted approach to the diagnosis, reduction, and bandaging of humeral fracture in Ancient Egypt, Greece, and Rome.

    The high incidence of venous leg ulcers and the difficult to give a complete healing involves in an increase of costs for National Health System. Main therapies to obtain a fast healing are compressive bandages, treatment of abnormal venous flow and in-situ-strategies of wound care. Negative pressure therapy does not conventionally used, because these systems not allow the use of compression bandages. Recently the development of ultraportable devices has improved the compliance and the results. Ten patients with venous chronic ulcer on the lower extremities were recruited for this study: all patients had venous leg ulcers from at least one year. We treated the patients with autologous partial thickness skin graft and subsequently we applied NANOVA device included in compressive bandage. We used NANOVA for fourteen days and after we made traditional medications. We submitted a questionnaire to evaluate the impact of dressing and NANOVA device in the quality of life of patients. The device contributed to the formation of granulation tissue and increased the success rate of autologous skin graft without limiting mobility of patient. In addition to this, we have been able to perform compression bandages thanks to small size of this device. Eight ulcers healed within 90 days of medication. We believe that ultraportable negative pressure systems are useful devices for treatment of venous leg ulcers because them allows to realize a compressive bandage without mobility limitations.

    Wearable electronics has emerged into the consumer markets over the past few years. Wrist worn and textile integrated devices are the most common apparatuses for unobtrusive monitoring in sports and wellness sectors. Disposable patches and bandages, however, represent the new era of wearable electronics. Soft and stretchable electronics is the enabling technology of this paradigm shift. It can conform to temporary transfer tattoo and deform with the skin without detachment or fracture. In this paper, we focus on screen-printed soft-electronics for remote body monitoring. We will present a fabrication process of a skin conformable electrode bandage designed for long-term outpatient electrocardiography (ECG) monitoring. The soft bandage is designed to be attached to the patient chest and miniaturized data collection device is connected to the bandage via Micro-USB connector. The fabricated bandage is tested in short exercise as well as continued long-term (72 hours) monitoring during normal daily activities. The attained quality of the measured ECG signals is fully satisfactory for rhythm-based cardiac analysis also during moderate-intensity exercise. After pre-processing, the signals could be used also for more profound morphological analysis of ECG wave shapes.

The warnings and recommendations of the implant manufacturers must be followed strictly to prevent complications, such as overheating, migration or demagnetization of the magnet in the implant. We report on a case of cochlear implant magnet dislocation as a complication for an MRI scan. The patient had a tight bandage around the head to hold the magnet in place as recommended by the manufacturer, but apparently the bandage was not in the correct place.

    Full Text Available The article describes the improvement of anaplerosis in patients with diabetic foot syndrome using skin flaps on vascular pedicle of the perforating vessels. The study involved patients with type 2 diabetes mellitus complicated with diabetic foot syndrome of neuroischemic form and chronic wounds of the lower extremities that do not heal for more than 21 days from the date of occurrence. The wounds were cleaned with ultrasonic cavitation. There was applied bandage with sorption antibacterial remedy base on nanodispersed silicon dioxide. There was applied a drainage vacuum bandage on a wound on the third day (VAC therapy. The flap is forming fitting to the size and configuration of a wound on a foot. Fourteen patients (93 % in the basic group were found to have survived flaps. Long-term follow up in 6 months demonstrated full maintenance of supporting function and good survived skin graft, absence of foot ulcers. In a control group 7 patients had recurrent foot ulcer. Improved techniques of autodermoplasty in patients with diabetic foot syndrome include glycemia control, preparation of a wound using vacuum apparatus bandage. Usage of split-skin graft combined with vacuum apparatus bandage allows close acute and chronic wounds effectively, maintain supporting function of an extremity, decrease in-hospital staying, and improve quality of patient’s life. Adequate foot wound closure prevents high-level amputation of low extremities in diabetic patients.

    Severe ankle sprains are a common presentation in emergency departments in the UK. We aimed to assess the effectiveness of three different mechanical supports (Aircast brace, Bledsoe boot, or 10-day below-knee cast) compared with that of a double-layer tubular compression bandage in promoting recovery after severe ankle sprains. We did a pragmatic, multicentre randomised trial with blinded assessment of outcome. 584 participants with severe ankle sprain were recruited between April, 2003, and July, 2005, from eight emergency departments across the UK. Participants were provided with a mechanical support within the first 3 days of attendance by a trained health-care professional, and given advice on reducing swelling and pain. Functional outcomes were measured over 9 months. The primary outcome was quality of ankle function at 3 months, measured using the Foot and Ankle Score; analysis was by intention to treat. This study is registered as an International Standard Randomised Controlled Trial, number ISRCTN37807450. Patients who received the below-knee cast had a more rapid recovery than those given the tubular compression bandage. We noted clinically important benefits at 3 months in quality of ankle function with the cast compared with tubular compression bandage (mean difference 9%; 95% CI 2.4-15.0), as well as in pain, symptoms, and activity. The mean difference in quality of ankle function between Aircast brace and tubular compression bandage was 8%; 95% CI 1.8-14.2, but there were little differences for pain, symptoms, and activity. Bledsoe boots offered no benefit over tubular compression bandage, which was the least effective treatment throughout the recovery period. There were no significant differences between tubular compression bandage and the other treatments at 9 months. Side-effects were rare with no discernible differences between treatments. Reported events (all treatments combined) were cellulitis (two cases), pulmonary embolus (two cases), and

    Approximately 30 % of all bone injuries are foot metatarsal fractures. Metatarsal V basis fractures occur most frequently. The classification is done into the tuberosity avulsion fractures, Jones fractures and stress fractures of the proximal diaphysis. The treatments of non-displaced fractures are generally conservative. The indication for surgical treatment depends on the load and the associated refracture rate. There are different types of treatment of these fractures. We present a possible approach to conservative treatments and show how different therapies affect healing of metatarsal V basis fractures and social reintegration of patients. A retrospective study consisted of 68 patients analysed during a 9-year period, whereas for a prospective analysis 18 patients were included for a period of 3 years. The treatment was performed using either a splint, closed bandage of the ankle or special Göttinger Anklesplint bandage, with immediate pain-oriented full load in all groups. The subjective and objective treatment results were analysed accoding the Göttinger Phillips score. In retrospect, the fracture consolidation was observed after 8.1 weeks full load-bearing was achieved after 6.3 weeks on average. In the prospective analysis, the osseous consolidation occurred after 6.2 weeks, and the full load was applied after 1.7 weeks. After 10 weeks the treatment with the Anklesplint bandage was assessed with 105 points of a maximum 110 points of the Phillips score. The Anklesplint bandage was also the cheapest option in the cost comparison. Using the immobilisation of the metatarsal supination with the Anklesplint bandage the metatarsal V basis fractures can heal in a regular way. The functional outcome is better in comparison to the that with other treatments and it is a cost-effective treatment. © Georg Thieme Verlag KG Stuttgart · New York.

    To investigate macro- and microperfusion during 14 days of treatment with a new 2-layer compression system (3M™ Coban™ 2 Lite), designed for patients with leg ulcer and concomitant peripheral arterial occlusive disease. A single-centre, open-label, prospective pilot study was performed with 15 subjects suffering from peripheral arterial occlusive disease with an ankle brachial pressure index (ABPI) of 0.5-0.8, who volunteered to have their 'study leg' bandaged with the new system. Coincident leg ulcer or chronic venous disease was not mandatory. All subjects received the new compression system, which stayed in place from 1 up to 4 days according to scheduled study visits. The system was reapplied by study personnel at each clinical visit (days 1, 2, 3, 4, 7, 10 and 14). The study participation stopped after 14 days. At each clinical visit safety assessments were performed: measurement of acral pulsation to capture macroperfusion; laser Doppler fluxmetry to capture microperfusion; clinical signs of pressure related skin damage, hypoxia-related pain and sub-bandage pressure measurement. In addition, the leg volume was measured and a comfort questionnaire was completed. An average sub-bandage pressure in standing position of approximately 30 mmHg was measured at the B1 location immediately after bandage application. Laser Doppler fluxmetry demonstrated positive effects on microcirculation regarding vasomotion and respiratory reflux. No change of the cardiac signal appeared. For acrale pulsations a high intraindividual variability was found with no clear interference to the bandage application. No pressure-related skin damage or hypoxia-related pain was detected. After application of the new compression system in subjects with moderate PAOD, laser Doppler fluxmetry indicated significant improvements of the microcirculation. High variability and lack of correlation to clinical symptoms was found for the acral pulsation. The new compression system revealed a high

  10. Feasibility and effectiveness of basic lymphedema management in Leogane, Haiti, an area endemic for bancroftian filariasis.

    Directory of Open Access Journals (Sweden)

    David G Addiss

    Full Text Available BACKGROUND: Approximately 14 million persons living in areas endemic for lymphatic filariasis have lymphedema of the leg. Clinical studies indicate that repeated episodes of bacterial acute dermatolymphangioadenitis (ADLA lead to progression of lymphedema and that basic lymphedema management, which emphasizes hygiene, skin care, exercise, and leg elevation, can reduce ADLA frequency. However, few studies have prospectively evaluated the effectiveness of basic lymphedema management or assessed the role of compressive bandaging for lymphedema in resource-poor settings. METHODOLOGY/PRINCIPAL FINDINGS: Between 1995 and 1998, we prospectively monitored ADLA incidence and leg volume in 175 persons with lymphedema of the leg who enrolled in a lymphedema clinic in Leogane, Haiti, an area endemic for Wuchereria bancrofti. During the first phase of the study, when a major focus of the program was to reduce leg volume using compression bandages, ADLA incidence was 1.56 episodes per person-year. After March 1997, when hygiene and skin care were systematically emphasized and bandaging discouraged, ADLA incidence decreased to 0.48 episodes per person-year (P<0.0001. ADLA incidence was significantly associated with leg volume, stage of lymphedema, illiteracy, and use of compression bandages. Leg volume decreased in 78% of patients; over the entire study period, this reduction was statistically significant only for legs with stage 2 lymphedema (P = 0.01. CONCLUSIONS/SIGNIFICANCE: Basic lymphedema management, which emphasized hygiene and self-care, was associated with a 69% reduction in ADLA incidence. Use of compression bandages in this setting was associated with an increased risk of ADLA. Basic lymphedema management is feasible and effective in resource-limited areas that are endemic for lymphatic filariasis.

  11. Treatment in the home setting with intermittent pneumatic compression for a woman with chronic leg ulcers: a case report.

    2017-01-01

    Intermittent Pneumatic Compression (IPC) is shown to improve the healing rate of Venous Leg Ulcers (VLU) in the hospital setting. The current Australian "Gold Standard" treatment according to the Australian and New Zealand Wound Management Associations' (AWMA) Prevention & Management of Venous Leg Ulcer guidelines is compression, generally in the form of bandaging then progressing to hosiery once wounds are healed to prevent recurrence. This is recommended in conjunction with other standards of wound management including; nutrition, exercise, client education and addressing underlying pathophysiology and psychosocial factors. Compression bandaging is predominantly attended by community nurses in the clients' home. Barriers to delivery of this treatment include; client concordance and or suitability for bandaging including client habitus, (shape of legs), client lifestyle, clinician knowledge and clinicians physical ability to attend bandaging, in particular for obese clients with limited mobility who pose a manual handling risk to the clinician themselves. The use of IPC may assist in mitigating some of these concerns, therefore it would seem wise to explore the use of IPC within the home setting. This paper will present an original case report on the successful treatment of a woman living with chronic bilateral lower leg ulcers using IPC as an adjunct treatment in her home. This paper supports recommendations to explore the use of IPC therapy in the home setting, for treatment of chronic leg ulcers requiring compression. Use of IPC in the home is anticipated to improve client involvement, concordance, client outcomes and reduce risk to staff applying conventional compression bandaging systems, particularly for obese clients with limited mobility.

    Carbon loaded polyethylene films were selected as the base substrate for a mechanically flexible and conductive sensing material for use wound monitoring technologies. The films were processed using laser ablation of the surface to increase the effective surface area of the electrode and then subject to an oxidative electrochemical etch to improve the electron transfer kinetics. The surface morphology of the resulting films was analysed and the electrode performance in relation to monitoring uric acid, a key wound biomarker, was optimized. A prototype smart bandage was designed, based on interfacing the mesh to a portable potentiostat, and the response to urate and potential interferences assessed. - Highlights: • Innovative use of a carbon–polyethylene mesh for wound sensing applications. • Electroanalytical characterisation of a mechanically flexible conductive film. • Design and preliminary characterisation of an integrated smart bandage.

    Lymphedema is a dreaded complication of breast cancer treatment. The standard care for lymphedema is complex decongestive physiotherapy, which includes manual lymphatic drainage (MLD), short stretch bandaging, exercise, and skin care. The Kinesio Taping could help to improve lymphatic uptake. We reported a patient with unilateral secondary malignant breast cancer-related lymphedema and arteriovenous (A-V) fistula for hemodialysis happened in the same arm, and used kinesio taping, MLD, and exercise to treat this patient because no pressure could be applied to the A-V fistula. The 12-session therapy created an excellent effect. We do not think the kinesio taping could replace short stretch bandaging, but it could be another choice for contraindicating pressure therapy patients, and we should pay attention to wounds induced by kinesio tape.

    The thrombosis of the inferior vena cava account for around the 15% of the cases of deep venous thrombosis. This is the case of a puerperal primigravida with a cesarean section labor presenting with a thrombosis initially in the right ovarian vein and then extension to the inferior vena cava. Treatment included low molecular weight heparin in anticoagulant doses; rest with elevation of the extremities and elastic bandage. After a satisfactory process evolution with partial lysis of the thrombus, the oral anticoagulation with Acenocumarol for 6 months was started. The second patient, a man aged 73 with backgrounds of an operated hepatic hydatidosis, had a thrombosis of the infrarenal inferior vena cava and agenesia of retrohepatic segment of the inferior vena cava. The patient remains with anticoagulant treatment including Acenocumarol, elastic bandage and hygienic care. As sequela he had a postphlebitic syndrome and reworsening of the edema leading to its admission in two occasions.(author)

  18. Lymphedema, lipedema, and the open wound: the role of compression therapy.

    Science.gov (United States)

    Macdonald, John M; Sims, Nancy; Mayrovitz, Harvey N

    2003-06-01

    As the science of wound healing has evolved over the past two decades, so has awareness of the "hidden epidemic" of lymphedema. Substantial information has been accumulated regarding the pathophysiology and therapy of lymphedema. Until recently, the relationship between wound healing and the negative effects of associated peri-wound lymphedema has received little attention. Identifying wound-related lymph stasis and safe mobilization of the fluid are fundamentals that must be addressed for proper therapy. Experience gained from the successful treatment of primary and secondary lymphedema has proven very useful in the applications to wound-related lymphedema. The mobilization of lymph fluid from the peri-wound area with the use of reasoned compression is essential for proper therapy of the open wound, as are appropriate bandage selection and safeguards for bandage application.

    Leduc, O; Leduc, A

    2002-01-01

    Edema of the upper limb is, frequently, very invalidating. The physical treatment for edema of the upper limb consists on a combination of different therapies: manual lymphatic drainage (MLD), intermittent sequential pressotherapy (IPP) with a very low intensity, multilayer bandages (MLB), and compression sleeves. Patients are not hospitalized. In the first step of physical treatment, the patients are treated daily during 2 or 3 weeks with different therapies (MLD, IPP and MLB). During the second step, bandages are no more used. The compression garments are applied after this 2 or 3 weeks period. The physical treatment consist now in: manual lynphatic drainage and intermittent sequential pressotherapy (with low intensity). The frequency of the physical treatment is progressively decreased.

    To describe the first veterinary use of a nanocrystalline silver dressing (NSD) and use of vacuum-assisted closure (VAC) to treat a severely burned dog. A 1-year-old female intact American Staffordshire Terrier with 50% total body surface area burned was referred for definitive care approximately 18-24 hours post injury. The dog was treated with crystalloid fluids, hydroxyethyl starch, and antimicrobials based on culture and sensitivity results of wound cultures, fresh frozen plasma, human serum albumin, and packed red cells. Wound care initially consisted of daily debridement under anesthesia with silver sulfadiazine application and bandaging. Because of the extent and the location of the wounds and morbid state of the patient, early wound grafting was not an option. Because of its reported improvement in granulation tissue formation and decreased tissue edema, VAC was used once the majority of burned tissue was manually debrided. Because of the pain caused by VAC and traditional bandaging techniques with this extent of injury, an NSD was utilized. This strategy was chosen due to the antimicrobial properties of NSD and the reduced necessity for daily bandage changes, which was reduced to only every 3 days. This protocol reduced the need for daily sedation or anesthesia. VAC and NSD were used successfully for the treatment of a severe burn injury in a dog. The use of NSD decreased the cost of therapy by reducing the need for daily bandage changes, thereby reducing the anesthetic and analgesic costs and allowing the patient to be managed on an outpatient basis.

    There is still controversy on the best compression therapy after performing a greater saphenectomy. The purpose of this study is to establish whether the use of a controlled compression stocking has the same level of safety and efficacy as a compression bandage in the immediate post-operative period after a greater saphenectomy. A prospective, randomised, open-labelled study, comparing three groups: a) a conventional compression bandage for one week, b) a conventional compression bandage replaced by a controlled tubular compression stocking at 5h of its putting in place, c) immediate direct use of the controlled tubular compression stocking, was conducted on fifty-five consecutive outpatients with a greater saphenectomy in one of their legs, and who fulfilled the inclusion criteria. The working hypothesis was that the controlled tubular compression stocking could replace, in terms of efficacy, safety and comfort, the usual controlled compression in the immediate post-operative period after saphenous vein stripping. The analysis variables were pain, control of bleeding, analgesics in the post-operative period, bruising, incapacity during the first week after the operation and comfort level. There were no statistically significant differences found between the three types of compressions studied as regards, safety, efficacy, comfort level, pain and analgesic consumption, but there was as regards the level of convenience in favour of the use of the stocking. The controlled tubular compression stocking can replace the compression bandage with more advantages after greater saphenous vein stripping in outpatients, having the same safety and efficacy.

    A method is described for producing molds which can be used in the construction of volumetric organ dosimeters. These negative organ molds are formed by wrapping quick-setting plaster bandages around a silicon-treated hardwood organ mold. The cast is cut in two and after further setting time is ready to contain the tissue equivalent materials and thermoluminescent powders. Such volumetric dosimeters will be useful for comparing experimental and calculated internal dosimetry results. (U.K.)

    Methanolic extracts of Typha elephantina inflorescence (TE) and its bandage were screened for wound healing by incision and excision wound models in Wistar rats. In the incision wound model, incision wounds were topically treated with TE gel (2.0% [w/w], 3.0% [w/w], and 5.0% [w/w]), Typha elephantina inflorescence bandage, and the reference standard 5.0% w/w povidone iodine for a period of 10 days. When the wounds healed thoroughly, sutures were removed on the 8th postwounding day, and the tensile strength of the skin was measured on the 10th day. In the excision wound model, excision wounds were treated with TE gel (3.0% [w/w] and 5.0% [w/w]), inflorescence bandage, and 5.0% w/w povidone iodine till the wounds completely healed. Epithelization time, wound contraction, hydroxyproline and hexosamine content of the scab, and ascorbic acid and malondialdehyde content of the plasma were determined in this model. In the incision wound model, high tensile strength of the skin of the healed wound was observed in rats treated with the TE gels and the inflorescence bandage when compared with wounded control rats. The increase in tensile strength indicates a promotion of collagen fibers and a firm knitting of the disrupted wound surfaces by collagen. In the excision wound model, higher rate of wound contraction, decreased period of epithelization, elevated hydroxyproline, hexosamine, and ascorbic acid levels, and a significant decrease in malondialdehyde content was observed in treated groups when compared with the wounded control animals. It may be concluded that the inflorescence of Typha elephantina possesses a potent wound healing activity, which may be due to an underlying antioxidant mechanism.

    The question whether or not a patient with an ankle brace should drive a car is of obvious importance because brake response time (BRT) is considered one of the most important factors for driving safety. Applying a crossover study design, 70 healthy participants (35 women, 35 men) participated in our study. BRT was assessed using a custom-made driving simulator. We assessed BRT under six conditions: without a brace (control) (1), with a typical postoperative ankle brace with adjustable ROM and the settings: unrestricted (2), fixed at 15° (3) plantar flexion, restricted with 15°/50° (4) (dorsal/plantar flexion), a brace for ligament instabilities (5) and an elastic ankle bandage (6). Participants were instructed to apply the brake pedal exclusively with the right foot as quickly as possible on receipt of a visual stimulus. The 70 participants showed significantly impaired BRT with the ankle brace for ROM restriction in the settings: unrestricted (p<0.001), fixed at 15° plantar flexion (p<0.001) and 15°/50° dorsal/plantar flexion (p<0.001) as compared to the control group. BRT was not impaired with the brace for ankle instabilities or the elastic ankle bandage. In conclusion, right-sided ROM restricting ankle braces involve significant impairment of BRT in healthy participants. No such prolonged BRT was found for an elastic ankle bandage or the ligament brace. Copyright © 2015 Elsevier Ltd. All rights reserved.

    To map skin temperature kinetics, and by extension skin blood flow throughout normal or abnormal repair of full-thickness cutaneous wounds created on the horse body and limb, using infrared thermography. Experimental. Standardbreds (n = 6), aged 3-4 years. Three cutaneous wounds were created on the dorsolateral surface of each metacarpus and on the lateral thoracic wall. Thoracic skin wounds and those on 1 randomly chosen forelimb healed by second intention without a bandage, whereas contralateral limb wounds were bandaged to induce formation of exuberant granulation tissue (EGT). Thermal data were collected from all planned wound sites before the surgical procedure (baseline), and at 24, 48, 96 hours, 1, 2, and 4 weeks after wounding. Data were analyzed using repeated measures ANOVA and a priori contrasts submitted to Bonferroni sequential correction. Level of significance was P temperature (CWT) increased temporally from preoperative period to week 1 postwounding, independently of anatomic location (P < .0001). CWT of limb wounds was significantly less than that of body wounds throughout healing (P < .01). CWT of limb wounds managed with bandages and developing EGT was significantly less than that of unbandaged limb wounds, which did not develop EGT (P ≤ .01). CWT varied with anatomic location and throughout healing. CWT of wounds developing EGT was significantly less than that of wounds without EGT. © Copyright 2012 by The American College of Veterinary Surgeons.

  3. Heavy Load Rollers in Logistic Systems

    Directory of Open Access Journals (Sweden)

    B. Künne

    2003-01-01

    Full Text Available Wheels with polyurethane bandages are in common use in logistic systems with friction gear actuation. Many research projects have studied the mechanical construction of these heavy load wheels. The studies have been theoretical as well as experimental. Research interests at the department of machine elements include the wear in the presence of intermediate material on the contact area between the bandage surface and the contact surface on which the wheel rolls off. This problem, which is observed when examining this tribochemical system, has not been studied before. Within this project both one-phase intermediate materials such as sand, water, cutting-cooling-emulsion, metal splinters and two-phase intermediate materials such as sand/water and combinations of the latter were taken into consideration. In addition, the exposure of the bandage hardness, the cross linking agent of the polyurethane, the mechanical stress, and the slip are observed. The analysis of the experimental results indicates that friction gear actuators can be constructed abrasion-optimised, taking into account special interfering effects in the form of intermediate materials in the contact area.

    This article presents successful incorporation of ibuprofen in polylactic acid (PLA) nanofibers to create scaffolds for the treatment of both acute and chronic wounds. Nanofibrous PLA scaffolds containing 10, 20, or 30 wt % ibuprofen were created and ibuprofen release profiles quantified. In vitro cytotoxicity to human epidermal keratinocytes (HEK) and human dermal fibroblasts (HDF) of the three scaffolds with varying ibuprofen concentrations were evaluated and compared to pure PLA nanofibrous scaffolds. Thereafter, scaffolds loaded with ibuprofen at the concentration that promoted human skin cell viability and proliferation (20 wt %) were evaluated in vivo in nude mice using a full thickness skin incision model to determine the ability of these scaffolds to promote skin regeneration and/or assist with scarless healing. Both acellular and HEK and HDF cell-seeded 20 wt % ibuprofen loaded nanofibrous bandages reduced wound contraction compared with wounds treated with Tegaderm™ and sterile gauze. Newly regenerated skin on wounds treated with cell-seeded 20 wt % ibuprofen bandages exhibited significantly greater blood vessel formation relative to acellular ibuprofen bandages. We have found that degradable anti-inflammatory scaffolds containing 20 wt % ibuprofen promote human skin cell viability and proliferation in vitro, reduce wound contraction in vivo, and when seeded with skin cells, also enhance new blood vessel formation. The approaches and results reported here hold promise for multiple skin tissue engineering and wound healing applications. © 2015 Wiley Periodicals, Inc.

    The objective of this investigation is to use a dental simulation model to compare splinting and bandaging methods for managing tooth avulsions and fractures, as measured by dentist evaluators for quality and time to complete each stabilization procedure. This was a randomized crossover study comparing 3 splinting techniques for managing a traumatically avulsed tooth (periodontal pack, wire, and bondable reinforcement ribbon) and 2 bandage techniques for managing a fractured tooth (calcium hydroxide paste and light-cured composite). After viewing a Just-in-Time training video, a convenience sample of emergency physicians performed the 5 stabilization techniques on dental models containing extracted teeth embedded in clay to simulate a segment of the human dentition. Data collected included time to complete each procedure, the evaluation of dentists about whether the procedure was performed satisfactorily or unsatisfactorily, and the ranking of dentists' and participants' preferred technique. Twenty-five emergency physicians participated in the study: 17 residents, 2 pediatric emergency medicine fellows, and 6 attending physicians. Reported median time, as well as minimum and maximum times to complete each splinting technique for an avulsed tooth, was as follows: periodontal pack 4.4 minutes (2.5 to 6.5 minutes), wire 8.6 minutes (5.8 to 12.9 minutes), and bondable reinforcement ribbon 8.9 minutes (5.6 to 15 minutes). Median time (and minimum and maximum times) to complete each protective bandaging technique for a fractured tooth was calcium hydroxide paste 4.6 minutes (3 to 9.6 minutes) and light-cured composite 7.1 minutes (5.5 to 14.1 minutes). When asked to choose a preferred splinting and bandaging technique according to the performance of the physicians, the dentists chose the bondable reinforcement ribbon 96% (24/25) and the light-cured composite 100% (25/25) of the time. Study participants had no measurable or agreeable preference for a particular splinting

    To report a case of bandage contact lens induced infectious keratitis caused by Pseudomonas aeruginosa following DSAEK. A 56-year-old female who underwent DSAEK at our institute for pseudophakic bullous keratopathy, developed contact lens induced keratitis in the fifth post operative week. Best corrected visual acuity (BCVA) reduced to perception of light in the left eye. Slit lamp examination revealed an epithelial ulcer measuring 4.7mm×6mm with surrounding infiltrates in the anterior stroma with hypopyon. The interface was clear. The corneoscleral rim culture of the donor tissue showed no growth on bacterial and fungal culture ruling out the possibility of donor-to-host transmission of infection. Microbiological evaluation identified the causative agent to be Pseudomonas aeruginosa. Based on culture and sensitivity report patient was started on hourly instillation of topical polymyxin B 20,000IU and fortified ceftazidime 5%. A response to treatment was noted and there was a complete resolution of keratitis with residual scarring. There have been case reports suggesting a host to donor transmission of infection which manifests during the postoperative period. To the best of our knowledge there are no reports of bandage contact lens associated Pseudomonas keratitis in a case that has undergone DSAEK. The prolonged use of bandage contact lens, lens contamination, stagnation of tear film behind the lens, compromised ocular surface and post operative use of topical steroids can contribute to infectious keratitis in DSAEK cases.

    To investigate the effect of 66% Manuka honey gel on the concentrations of transforming growth factor (TGF)-β1 and TGF-β3, bacterial counts and histomorphology during healing of contaminated equine distal limb wounds. In this experimental study of 10 Standardbred horses, five full-thickness skin wounds (2 × 1.5 cm) were created on one metacarpus and six similar wounds were created on the contralateral metacarpus. Wounds were assigned to three groups: non-contaminated control wounds; contaminated control wounds; contaminated wounds treated daily with 1 mL Manuka honey gel topically for 10 days. For the contaminated wounds, faeces were applied for 24 h after wound creation. In five horses wounds were bandaged and in the other five horses wounds were left without a bandage. Biopsies were taken on days 1, 2, 7 and 10 after wounding to evaluate the effects of Manuka honey gel, wound contamination and bandaging on TGF-β1 and TGF-β3 concentrations, aerobic and anaerobic bacterial counts, and histomorphology. Manuka honey gel had no significant effect on TGF-β1 and TGF-β3 concentrations or wound bacterial counts. Manuka honey gel decreased wound inflammation (days 7, 10), increased angiogenesis (days 2, 7, 10), increased fibrosis and collagen organisation (day 7) and increased epithelial hyperplasia (days 7, 10). Treatment with Manuka honey gel resulted in a more organised granulation tissue bed early in wound repair, which may contribute to enhanced healing of equine distal limb wounds. © 2016 Australian Veterinary Association.

  8. Fabrication of Non-Implant 3D Printed Skin

    2018-01-01

    Full Text Available Many bandages tend to be harmful when being removed from the human skin. This is a crucial issue, especially faced by burn victims. When bandages are removed from the burn wound, they tend to be harmful by peeling off the newly formed layer of skin over the burn wound. Such nature causes the patient to endure a longer recovery time with additional pain. The objective of this project is to 3D print artificial skin for the victims of burn wounds by using natural gelation. The main aim for creating the artificial skin will be used in place of the current burn wound treatment techniques of dressing the wounds in bandages. The inner layer of this skin was lined with a natural adhesive, a thin layer of agar-agar, which has been reinforced with crushed eggshells to increase its adhesive strength and durability. The synthesized gel contained non adhesive behavior, yet aids in wound healing abilities. Applying hydrocolloids ensures that the wound is kept cool and the gel also ensures efficient heat transfer. This was done so that less sweating occurs on the patient. Based on the experiments that were conducted, the results conclude that the best ratio of artificial skin layer would be 2:1 of agar gel: crushed eggshells. This golden ratio of gel: crushed eggshells for the longest period of time for attachment on the skin without sweating, is achieved. The skin will be printed using Acrylonitrile-Butadiene-Styrene (ABS. The colour of the skin and the shape of the skin was individually designed for each specific patient. The inner gel has the capabilities of reducing the rehabilitation time, without compromising the comfort of the patient. This approach has the potential to be used as a new method to treat burn wounds..

    To determine whether transforming growth factor (TGF)-beta1 and -beta3 expression differs between equine limb wounds healing normally and those healing with experimentally induced exuberant granulation tissue (EGT). Six wounds were created on the lateral aspect of both metacarpi of each horse; one forelimb was untreated, and the other was bandaged to stimulate the development of EGT. Sequential wound biopsies allowed comparison of growth factor expression between the two types of wound. Four horses (2 to 4 years of age; 350 to 420 kg). Wounds were assessed grossly, histologically, and by enzyme-linked immunosorbent assay (ELISA) for TGF-beta1 and -beta3 expression at 12 and 24 hours and 2, 5, 10, and 14 days postoperatively. Bandaged wounds developed EGT. In all wounds, TGF-beta1 peaked early and remained elevated at 14 days. Peak TGF-beta1 concentration was higher in wounds with EGT, but not significantly so. Expression of TGF-beta3 differed from TGF-beta1, with peak TGF-beta3 concentrations being delayed. Concentrations of TGF-beta3 were higher in wounds healing normally, but this difference was not significant. During both normal and exuberant wound repair, the expression of TGF-beta1 occurred earlier than TGF-beta3 expression. Wounds healing with EGT tended to have higher concentrations of fibrogenic TGF-beta1 and lower concentrations of antifibrotic TGF-beta3 than wounds healing normally, although these differences were not statistically significant. This study suggests that the production of EGT in bandaged wounds may be related to increased expression of fibrogenic TGF-beta1 and decreased expression of antifibrotic TGF-beta3. Further investigation of the roles of TGF-beta1 and -beta3 may be important in understanding the molecular control of EGT in horses. Copyright 2002 by The American College of Veterinary Surgeons

  10. Commentary: Europe needs a central, transparent, and evidence based regulation process for devices

    . Medical devices range from bandages to life support machines, and manufacturers classify them into four risk categories from low (such as urine drainage bags) to high risk (such as drug eluting cardiac stents) according to EU rules.2 The risk associated with the device depends on the duration of contact...... with the body, invasiveness, and whether it has a local or a systemic effect. Medium and high risk devices must be certified by one of the notified bodies, organisations that are accredited to assess a product’s compliance with EU legislation (CE mark). At a first glance this seems a structured process...

    Three hydrogels were assessed in respect of water-vapour transmission and conformability. These materials were tested alone and as part of a bilaminate dressing which incorporates an adhesive top layer. The adhesive layer used in this study was a compliant adhesive bandage, marketed under the name Mefix. It was observed that this layer reduced the normally high water-vapour transmission rates of the hydrogels to much lower, clinically more acceptable, levels. Mechanically, the Mefix layer protects the underlying hydrogel, prevents tearing and puncturing but decreases conformability by elastic restraint.

    The underutilized practice of photographing anatomic pathology specimens from surgical pathology and autopsies is an invaluable benefit to patients, clinicians, pathologists, and students. Photographic documentation of clinical specimens is essential for the effective practice of pathology. When considering what specimens to photograph, all grossly evident pathology, absent yet expected pathologic features, and gross-only specimens should be thoroughly documented. Specimen preparation prior to photography includes proper lighting and background, wiping surfaces of blood, removing material such as tubes or bandages, orienting the specimen in a logical fashion, framing the specimen to fill the screen, positioning of probes, and using the right-sized scale.

    Full Text Available Background: Ipomoea batatas (L. Lam. from the family Convolvulaceae is the world’s sixth largest food crop. The tubers of Ipomoea batatas commonly known as sweet potato are consumed as a vegetable globally. The tubers contain high levels of polyphenols such as anthocyanins and phenolic acids and vitamins A, B and C, which impart a potent antioxidant activity that can translate well to show wound healing effects. To check their effects on wound healing, the peels and peel bandage were tested on various injury models in rats in the present study.Methods: The methanolic extracts of the peels and peel bandage of Ipomoea batatas tubers (sweet potato were screened for wound healing by excision and incision wound models on Wistar rats. Three types of gel formulations were prepared, viz., gel containing 3.0% (w/w peel extract, gel containing 6.0% (w/w peel extract and gel containing 10% (w/w peel extract. Betadine (5% w/w povidone iodine cream was used as a reference standard. In the incision wound model, Tensile strength of the skin was measured. Epithelization time, wound contraction, hydroxyproline content of the scab, and ascorbic acid and malondialdehyde content of the plasma were determined in the excision wound model.Results: In the incision wound model, high tensile strength of the wounded skin was observed in animals treated with the peel extract gels and the peel bandage when compared with wounded control animals. The increase in tensile strength indicates the promotion of collagen fibers and that the disrupted wound surfaces are being firmly knit by collagen. In the excision wound model, significant wound closure was observed on the 4th day in rats treated with all three gel formulations when compared with the wounded control rats.

    Full Text Available Suicides by intravenous injection of an overdose of medicaments are uncommon. In this paper, we present the case of a suicide by rocuronium-bromide injection in combination with an oral overdose of metoprolol. Unfortunately, in Belgrade, there is no toxicological laboratory capable of detecting rocuronium. The interpretation of autopsy and toxicological data in this case was made difficult due to the extreme putrefaction of the body of the deceased. So, by forensic investigation, the case was solved indirectly, through circumstantial evidence: an empty ampoule of rocuronium found near the body, as well as a plastic syringe and cloth-bandage found in the left hand of the deceased.

    The methods of calculation of contact stresses during cylinder shell tube - steel bandage interaction are presented. Tymoshenko`s generalized theory of shells serves as a basis for investigating steel head to fiberglass sucker rod joint strength. This theory allows to consider mechanical performance of composite materials. The problem is reduced to solving Fredholm integral equation of second degree. The numeric analysis is performed. Several joints of composite body with steel head are proposed. The full-size sucker rod fatigue tests are performed to determine the fatigue limit under the bending and axial cyclic loads in the medium of oil well fluids. (orig.)

  17. Managing ankle sprains in primary care: what is best practice? A systematic review of the last 10 years of evidence.

    Seah, Richard; Mani-Babu, Sivanadian

    2011-01-01

    To summarize the best available evidence in the last decade for managing ankle sprains in the community, data were collected using MEDLINE database from January 2000 to December 2009. Terms utilized: 'ankle injury primary care' (102 articles were found), 'ankle sprain primary care' (34 articles), 'ankle guidelines primary care' (25 articles), 'ankle pathways primary care' (2 articles), 'ankle sprain community' (18 articles), 'ankle sprain general practice' (22 articles), 'Cochrane review ankle' (58 articles). Of these, only 33 satisfied the inclusion criteria. The search terms identified many of the same studies. Two independent reviewers reviewed the articles. The study results and generated conclusions were extracted, discussed and finally agreed on. Ankle sprains occur commonly but their management is not always readily agreed. The Ottawa Ankle Rules are ubiquitous in the clinical pathway and can be reliably applied by emergency care physicians, primary care physicians and triage nurses. For mild-to-moderate ankle sprains, functional treatment options (which can consist of elastic bandaging, soft casting, taping or orthoses with associated coordination training) were found to be statistically better than immobilization for multiple outcome measures. For severe ankle sprains, a short period of immobilization in a below-knee cast or pneumatic brace results in a quicker recovery than tubular compression bandage alone. Lace-up supports are a more effective functional treatment than elastic bandaging and result in less persistent swelling in the short term when compared with semi-rigid ankle supports, elastic bandaging and tape. Semi-rigid orthoses and pneumatic braces provide beneficial ankle support and may prevent subsequent sprains during high-risk sporting activity. Supervised rehabilitation training in combination with conventional treatment for acute lateral ankle sprains can be beneficial, although some of the studies reviewed gave conflicting outcomes

    A 16-year-old American paint horse gelding was presented for evaluation of a left forelimb lameness grade III/V. Radiographs and computed tomography revealed a comminuted fracture of the accessory carpal bone involving the entire articulation with the distal radius and the proximal aspect of the articulation with the ulnar carpal bone. Multiple fragments were present in the palmar pouch of the antebrachiocarpal joint. An arthroscopic-assisted open approach was necessary to remove all fractured fragments. Subsequently the horse was re-admitted for lameness and was treated successfully with antibiotics and long-term supportive bandaging.

    We describe a case of recipient bed melt and wound dehiscence after uneventful penetrating keratoplasty and subconjunctival injection of bevacizumab. Three weeks postoperatively, the patient presented with limbal ischemia, recipient bed melt, and wound dehiscence corresponding to the area of bevacizumab injection. The melt was managed by application of cyanoacrylate glue along with bandage contact lens. Although the graft survived, there was a problem in re-epithelization. This case highlights the need for further studies to elucidate the therapeutic dose, side effects, and correct timing of using bevacizumab with respect to corneal transplant surgery.

    2011-07-01

    Lymphedema and lipedema are chronic progressive disorders for which no causal therapy exists so far. Many general practitioners will rarely see these disorders with the consequence that diagnosis is often delayed. The pathophysiological basis is edematization of the tissues. Lymphedema involves an impairment of lymph drainage with resultant fluid build-up. Lipedema arises from an orthostatic predisposition to edema in pathologically increased subcutaneous tissue. Treatment includes complex physical decongestion by manual lymph drainage and absolutely uncompromising compression therapy whether it is by bandage in the intensive phase to reduce edema or with a flat knit compression stocking to maintain volume.

    2009-08-01

    Methods to compress thigh veins effectively after venous surgery or endovenous procedures are still disputed. The aim of this paper was to compare the clinical outcomes with three different compression devices as a function of the pressures exerted. Fifty-four patients undergoing invagination stripping of the great saphenous vein and side branch evulsion under local anaesthesia were treated postoperatively in sequential order by 1) thigh length compression stockings; 2) adhesive bandages; and 3) newly developed eccentric compression pads fixed with tapes and a thigh length stocking on top. Sub-bandage pressures were measured at mid-thigh level under these devices after application and one week later before compression was removed. Pain, hematoma, bleeding through the bandage, discomfort and skin irritations were recorded and rated as major or minor adverse events. The lowest sub-bandage pressure of around 15 mmHg at thigh level in the lying position were found in group A under the compression stockings, which nominally provide 23-32 mmHg at ankle level. Group B and group C showed significantly higher values (median values of 47 and 68 mmHg respectively in lying position, Ppressure values in the three groups upon standing were 16 mmHg, 63 mmHg and 98 mmHg. One week later there was a pressure-drop in the lying position in the three groups of 13%, 64%, and 46% respectively. Major adverse events were seen in a total of 10 of 18 patients in group A, in 1/18 in group B, and in 0/18 in group C. Minor adverse events in the three groups consisting mainly of light discomfort for compression devices and local skin irritations were observed in 6, 6 and 15 cases respectively. The best results with respect to the reduction of pain and hematoma were obtained when eccentric compression pads were taped to the skin of the thigh and a compression stocking was worn on top. A possible explanation for these observations is the very high local pressures under the eccentric device.

    This small treatise does not appear to have been published in Danish in its entirety. It gives a vivid picture of the physician in ancient Greece. The well known first chapter describes the attitudes and attributes of the doctor. It goes on discussing in some detail how the light should be in the surgery, the instruments to be used, the preparations of bandages and drugs, and the use of cupping instruments. The author stresses both the needs of the patient and the necessity of the physician's dignity and integrity.

    Inherently superhydrophobic and flexible cellulose-based bionanocomposites were fabricated from solid stabilized (Pickering) emulsions. Emulsions were formed by dispersing cyclosiloxanes in water stabilized by layered silicate particles and were subsequently modified by blending into a zinc oxide nanofluid. The polymer matrix was a blend of cellulose nitrate and fluoroacrylic polymer (Zonyl 8740) precompatibilized in solution. Coatings were spray cast onto aluminum substrates from polymer blends dispersed in modified Pickering emulsions. No postsurface treatment was required to induce superhydrophobicity. Effect of antiseptic additives on bionanocomposite superhydrophobicity is also discussed. Replacing cellulose nitrate with commercial liquid bandage solutions produced identical superhydrophobic coatings.

    1978-03-01

    In 330 consecutive anesthetics administered over a period of 24 months, an improved method of upper extremity intravenous regional anesthesia, entitled "the second wrap technique," included wrapping the extremity a second time with a Martin rubber bandage after the extremity was prepared and draped. In addition, a Penrose drain tourniquet often was applied during injection of the 0.5% lidocaine. No complications occurred. The technique provides a nearly bloodless operative field, improves the anesthesia, diminishes tourniquet pain, lessens the contraindications, and requires no premedication. The only contraindications are allergy to lidocaine, infection, operating time over 2 hours, and severe hypertension.

    Complications associated with diagnostic native percutaneous renal biopsy (PRB) must be minimized. While life threatening major complications has been extensively investigated, there is little discussion regarding minor bleeding complications, such as a transient hypotension, which directly affect patients' quality of life. There is also little evidence supporting the need for conventional manual compression following PRB. Therefore, this study evaluated the relationship between minor and major complications incidence in patients following PRB with or without compression. This single-center, retrospective study included 456 patients (compression group: n = 71; observation group: n = 385). The compression group completed 15 min of manual compression and 4 h of subsequent strict bed rest with abdominal bandage. The observation group completed 2 h of strict bed rest only. The primary outcome of interest was transient symptomatic hypotension (minor event). Of the 456 patients, 26 patients encountered intraoperative and postoperative transient hypotension, which were considered reflex syncope without tachycardia. Univariate analysis showed that symptomatic transient hypotension was significantly associated with compression. This association remained significant, even after adjustment of covariates using multivariate logistic regression analysis (adjusted odds ratio 3.27; 95% confidential interval 1.36-7.82; P = 0.0078). Manual compression and abdominal bandage significantly increased the frequency of reflex syncope during native PRB. It is necessary to consider the potential benefit and risk of compression maneuvers for each patient undergoing this procedure.

    Magnetic resonance imaging (MRI) has become an indispensable aid to diagnosis and treatment. As the doctor cannot accompany the patient, it is essential that the patient be monitored remotely to avoid the risk of respiration being impaired by anesthetic drugs or upper airway obstruction. A smart wearable textile sensing system is described in this paper. A fiber Bragg grating (FBG) with polymer encapsulation has been woven into an elastic bandage to detect the respiration motion. According to the strain principle of FBG, the breathing rate and intensity can be obtained by measuring the variety of FBG reflected wavelength. In order to eliminate the temperature cross-sensitivity, a FBG temperature sensor has also been woven into the bandage to achieve the temperature compensation computing. Based on the tunable Fabry-Perot filter wavelength demodulated theory, wavelength measuring method and data processing arithmetic have been presented, and the system with ARM microprocessor has been designed to process and display the breathing information. The experiments to the system have proved that the wavelength measuring range is about 40nm, the resolution of wavelength can arrive at 2pm, and the sampling rate is 5Hz.

    Vulvar lymphedema is an uncommon and disabling side-effect of pelvic lymphadenectomy and pelvic radiotherapeutic treatment for invasive genital cancer. Lymphorrhea, a complication of lymphedema, may be extremely distressing for patients due to the requirement to wear sanitary towels and as the pain and loss of elasticity of the vulvar skin and mucosa can cause discomfort during coitus. Surgical treatments of lymphorrhea and vulvar lymphedema secondary to gynecological cancer treatments remain controversial and are not currently considered to be the standard therapy. The present study reports two cases of vulvar lymphedema complicated by vulvar lymphorrhea in females who had undergone treatment for cervical and endometrial cancer, respectively; a review of the literature is also included. In the two present cases, vulvar lymphedemas were refractory to standard treatments, including decongestive therapy, manual lymph drainage, elastic bandaging, low-stretch bandaging, exercises and skin care. Laser CO 2 excision and vaporization of the whole skin and mucosal tissue of the vulva was successfully performed to treat the lymphorrhea and improve quality of life. Thus, the present two cases indicated that laser CO 2 surgery may present an additional therapy for the treatment of genital lymphedema that is refractory to other treatments.

    Full Text Available Background and Design: Treatment of chronic venous ulcers of the lower extremity is still an important difficulty. The principal treatment of these ulcers includes compression therapy, local wound care and surgery. Unresponsiveness to these standard treatments is a frequent situation with negative effects on life quality and reductions in personal productivity. Therefore, there is a need for new applications to increase the effectiveness of treatment in treatment-resistant cases. In the present study, we retrospectively evaluated the results of topical application of amelogenin extracellular matrix protein in resistant venous ulcers. Materials and Methods: We analyzed the records of patients with treatment-resistant venous ulceration who were treated with amelogenin extracellular matrix protein between June 2011 and December 2012.. Results: 26 patients (21 male and 5 female with a total number of 28 ulcers (24 patients with 1 ulcer, 2 patients with two ulcers were evaluated. The patients were treated with topically applied amelogenin extracellular matrix protein and regional four bandage compression. Bandages were changed weekly. Each cure continued for six weeks. In fourteen patients (15 ulcers, we observed a complete healing by the end of the first cure. In another twelve cases (13 ulcers, the same period resulted with a reduction in wound diameter. We continued to the second cure for these patients. By the end of the second cure, complete healing was achieved in five cases (6 ulcers. Conclusion: Topical application of amelogenin extracellular matrix protein may be considered as an effective therapeutic choice for refractory venous ulcers.

    Complete olecranon bursectomy with debridement, protection of veins and nerves. Risk-adapted antibiotic therapy and early functional aftercare. Acute, traumatic laceration of the bursa olecrani, chronic therapy-resistant bursitis olecrani. For traumatic bursa injuries: general contraindications for anesthesia and surgery; chronic bursitis: initially not closable skin defect (plastic surgery required), hemodynamically instable patient (e.g. systemic inflammatory response syndrome [SIRS] or sepsis), pre-existing skin infection. Local anesthesia beyond the lesion, careful debridement, identification and removal of the entire bursa, excision of contaminated skin, lavage, drain insertion (Redon, Easy-flow, Penrose). Wound closure, elastic bandage, and splint. Elastic bandage for 2 days, followed by drain removal. Wound assessment, early functional aftercare without splint, antibiotic therapy in septic bursitis for 2 weeks, PRICE scheme. Removal of stitches after 10-12 days. Over 5 years, 138 cases of traumatic bursa lesion or chronic bursitis olecrani were treated in our clinic, 82 patients underwent surgery. Ten patients were treated with vacuum-assisted closure therapy and consecutive wound healing; fistulae occurred in two patients and in another two dehiscence developed. All of the defects could be closed without flaps.

    Ivor S. Vanhegan

    2012-01-01

    Full Text Available A 72 year-old-male was referred to our institution with recalcitrant prepatellar bursitis. The injury was sustained after striking his right knee against a post whilst horse riding 9 months ago. Previous treatments included repeated aspiration and excision of the bursa with elastic compression bandaging. A diagnosis of a Morel-Lavallée internal degloving injury was made, and the lesion was satisfactorily managed by an internal quilting procedure to eliminate the potential dead space. A review of the literature reveals 29 published reports of Morel-Lavallée lesions with sufficient information for inclusion. These came from 14 separate countries with a total of 204 lesions in 195 patients. The most common anatomical location was the greater trochanter/hip (36%, followed by the thigh (24% and the pelvis (19%. Most were managed surgically with evacuation of the haematoma and necrotic tissue followed by debridement, which was often repeated (36%. Conservative treatment with percutaneous aspiration and compression bandaging was the next most common treatment (23%. The knee was the fourth most common region affected (16%, and only 3 other lesions in the literature have been managed with a quilting procedure.

    This paper presents our efforts in the development of a small wireless, flexible bandage sized near-infrared spectroscopy (NIRS) system for sleep analysis. The current size of the system is 2.8 cm × 1.7 cm × 0.6 cm. It is capable of performing NIRS with 660nm, 940nm and 850nm wavelengths for up to 11 hours continuously. The device is placed on the forehead to measure from the prefrontal cortex and the raw data is continuously streamed over Bluetooth to a nearby data aggregator such as a smartphone for post processing and cloud connection. In this study, we performed traditional polysomnography simultaneously with NIRS to evaluate agreement with traditional measures of sleep and to provide labelled data for future work involving learning algorithms. Ultimately, we expect a machine learning algorithm to be able to generate characterization of sleep states comparable to traditional methods based on this biophotonics data. The system also includes an inertial measurement unit and the features that can be extracted from the presented system include sleep posture, heart rate, respiratory rate, relative change in oxy and deoxy hemoglobin concentrations and tissue oxygenation and cerebral arterial oxygen extracted from these. Preliminary proof of concept results are promising and demonstrate the capability to measure heart rate, respiratory rate and slow-wave-sleep stages. This system serves as a prototype to evaluate the potential of a small bandage-size continuous-wave NIRS device to be a useful means of studying sleep.

    To describe a patient with cone dystrophy who presented with acute hydrops and perforation, leading to the diagnosis of keratoconus. Case report and literature review. A 21 -year-old male patient with a history of cone dystrophy presented with a flat anterior chamber, diffuse corneal stromal edema with an intrastromal cleft, and ruptured Descemet membrane, findings consistent with acute hydrops with corneal perforation. After bandage contact lens placement and instillation of a cycloplegic agent, the anterior chamber reformed within 24 hours. Over the next week, conservative management with a bandage lens, pressure patching, topical fluoroquinolone antibiotic, and topical cycloplegic led to the reformation and maintenance of anterior chamber stability. Corneal topography of the unaffected eye showed global corneal thinning and steep sim K readings suspicious for early keratoconus. Although the association between keratoconus and cone dystrophy is extremely rare, our patient's vision-threatening complication of acute hydrops with corneal perforation highlights the importance of corneal evaluation including topography in cone dystrophy. Conservative management was successful in the restoration of anatomic integrity in this situation.

    2012-07-01

    To report 2 cases of fungal keratitis and endophthalmitis in patients with the type 1 Boston keratoprosthesis (KPro) in India. Two patients underwent type 1 Boston KPro with uneventful intraoperative and early postoperative courses. The patients presented with keratitis and endophthalmitis within a few months after surgery. Both patients had soft bandage contact lenses in place and were on maintenance low-dose topical steroids and antibiotic eyedrops. Culture was positive for fungus in both the cases. Despite aggressive antifungal medical therapy and surgical management, one patient's eye was eviscerated and the other lost the potential for any useful vision. Fungal infection after KPro surgery can be devastating, negating the extraordinary visual recovery these patients achieve immediately after surgery. Chronic use of topical corticosteroids and broad-spectrum antibiotic and bandage contact lens, although indispensable, may enhance the risk of fungal infection especially in the endemic areas like India. The decision for KPro in such tropical climatic conditions should therefore be taken with absolute caution and frequent patient follow-up. A prophylactic antifungal regime may be mandatory when this procedure is undertaken in fungal endemic areas to improve outcomes.

    Compression therapy, together with modern moist wound treatment, is the basis for a successful conservative treatment of patients with chronic leg ulcers. In clinical practice, it is often the patients themselves who apply compression therapies. Many of the mostly elderly patients, however, are not able to reach their legs and feet due to movement restrictions, such as arthritis, arthrosis and even obesity. An adequate compression therapy also requires extensive experience and regular training. In practice only the minority of patients can perform bandaging well and therefore this should not be recommended. Self-management with do-it-yourself medical devices will become more and more important in the future. In addition to the psychological factors, cost aspects and demographic change, an expected lack of qualified nursing staff due to the number of elderly patients who are potentially in need of care means that self-management is becoming increasingly more important. For the essentially important compression therapy of patients with chronic leg ulcers, there already exist various therapy options. The needs, preferences and abilities of the patients concerned can be considered when selecting the appropriate system. Particularly for the self-management of compression therapy, adaptive compression bandages are suitable for patients with leg ulcers during the initial decompression phase and ulcer stocking systems in the subsequent maintenance phase.

    The funeral preparations for ancient Egyptian dead were extensive. Tomb walls were often elaborately painted and inscribed with scenes and objects deemed desirable for the afterlife. Votive objects, furniture, clothing, jewelry, and importantly, food including bread, cereals, fruit, jars of wine, beer, oil, meat, and poultry were included in the burial goods. An intriguing feature of the meat and poultry produced for the deceased from the highest levels of Egyptian society was that they were mummified to ensure their preservation. However, little is known about the way they were prepared, such as whether balms were used, and if they were used, how they compared with those applied to human and animal mummies? We present herein the results of lipid biomarker and stable carbon isotope investigations of tissues, bandaging, and organic balms associated with a variety of meat mummies that reveal that treatments ranged from simple desiccation and wrapping in bandages to, in the case of the tomb of Yuya and Tjuia (18th Dynasty, 1386–1349 BC), a balm associated with a beef rib mummy containing a high abundance of Pistacia resin and, thus, more sophisticated than the balms found on many contemporaneous human mummies.

    Full Text Available Abstract Background FlaxAid is a newly developed type of dressing enriched in particular flavonoids through genetic engineering of flax plants that exhibit health-promoting activities due to their strong antioxidant properties. The purpose of the current study was to assess the clinical efficacy of the FlaxAid bandage therapy for a patient affected with a diabetic foot ulcer which was unresponsive to previous treatments. The patient was treated with FlaxAid bandages for 12 weeks and the size and properties of the wound were routinely observed and recorded. Due to the the clinical picture of the wound study design was adopted whereby the comparative treatment was cotton gauze wetted with isotonic salt solution. Findings Following therapy, the foot ulcer decreased in size, despite the decompensation of advanced diabetes. It is believed that the beneficial nature of FlaxAid is derived from its high level and broad spectrum of antioxidants. Conclusions The FlaxAid dressing provides a novel and effective method for the treatment of diabetic foot ulcers. This study presents a preliminary pilot investigation and a larger number of subjects need to be included within the study in order to draw firm clinical conclusions. Efforts to this effect are currently under way.

    As imaging technologies become increasingly advanced, it is possible to obtain detailed morphological information as well as functional imaging data. In some imaging technologies, the radiation dose increases with the ability to obtain better images or more detailed information. We encountered three cases of temporary bandage-shaped hair loss, which was caused by perfusion studies of the head by multi-detector row computed tomography (MDCT) for evaluation of cerebral blood flow in patients with vascular disorders. In all three patients with temporary hair loss, two angiographies of the head had been performed in the period of serial CT examinations. This suggested the possibility that radiation exposure from angiography performed in serial examinations, combined with the perfusion studies of the head with MDCT, played an important role in this temporary, bandage-shaped hair loss. Radiologists should be aware that a cumulative or multiplier effect of radiation exposure from multiple diagnostic techniques may result in hair loss and other types of radiation complications.

    As most hemangiomas and tattoos require many sessions to be cured completely by argon-laser or conventional therapy I developed a new combined surgical and laser-therapy method for large hemangiomas and tattoos. This is a three step method. First: The skin lesion is treated by argon-laser with the point by point method, developed by ourself. Second: Under local or general anaesthesia a) the hemangioma is partially excised and undermined letting only the skin which is already treated by argon-laser-beams. Than the hemangioma is exstirpated in toto, the wound closed by running intradermal sutures and a pressure bandage applied, b) the tattoo is abraded as deep as possible, draped by lyofoam. Then a pressure bandage is applied. Third: The hemangioma as well as the tattoo are treated by argon-laser-beams after the operation. This method is safe and effective, gives good results, minimal scars in the case of hemangiomas and tattoos. In this paper the method is described and some cases are illustrated by pre- and postoperational photographs.

    Highlights: • ZnO nanoparticles obtained by pulsed laser ablation exhibit antibacterial activity. • H{sub 2}O{sub 2} and Zn{sup 2+} are not responsible for antibacterial activity of obtained zinc oxide. • Nano-ZnO/cotton fabric composite is a promising material for antibacterial bandage. - Abstract: A simple deposition method was used to prepare a ZnO/cotton fabric composite from water and ethanol dispersions of ZnO nanoparticles obtained by the pulsed laser ablation method. The structure and composition of the nanoparticles from dispersions and as-prepared composites were studied using electron microscopy, X-ray diffraction, and spectroscopy. The nanoparticles and composite obtained exhibited antibacterial activity to three different pathogenic microorganisms—Escherichia coli, Staphylococcus aureus, and Bacillus subtilis. An attempt to understand a mechanism of bactericidal effect of ZnO nanoparticles was made. It was shown that zinc ions and hydrogen peroxide were not responsible for antibacterial activity of the particles and the composite, and surface properties of nanoparticles played an important role in antibacterial activity of zinc oxide. The proposed composite is a promising material for use as an antibacterial bandage.

    Full Text Available Abstract Background Tienchi (Panax notoginseng has been used in conservative treatments for back pain as a major ingredient of many herbal medicines. This study aims to investigate the effects of a herbal medicine containing tienchi on compressed intervertebral discs in rats. Methods Using an in vivo rat tail model, intervertebral disc compression was simulated in the caudal 8–9 discs of 25 rats by continuous static compression (11 N for 2 weeks. An herbal medicine plaster (in which the major ingredient was tienchi was externally applied to the compressed disc (n=9 for three weeks, and held in place by an adhesive bandage, in animals in the Chinese Medicine (CM group. The effect of the bandage was evaluated in a separate placebo group (n=9, while no intervention with unrestricted motion was provided to rats in an additional control group (n=7. Disc structural properties were quantified by in vivo disc height measurement and in vitro morphological analysis. Results Disc height decreased after the application of compression (P P = 0.006 and placebo (P = 0.003 groups, but was maintained in the CM group (P = 0.494. No obvious differences in disc morphology were observed among the three groups (P = 0.896. Conclusion The tienchi-containing herbal plaster had no significant effect on the morphology of compressed discs, but maintained disc height in rats.

    2017-09-01

    Full Text Available Case summary An approximately 3-year-old, male domestic longhair cat was presented to a mobile veterinary unit for routine neuter. Preoperative physical examination revealed an approximately 5 cm × 2 cm scab on the craniolateral portion of the left antebrachium. The cat was anesthetized for the neuter using an injectable anesthesia protocol. After castration, the wound area on the antebrachium was clipped, copiously lavaged and the wound edges were surgically debrided. Injectable antibiotics and analgesic management were instituted. The wound was conservatively managed using sugar bandaging and antibiotic dressings until the progression of healing plateaued. Procedures for closing the defect were explored, and it was decided that a single-pedicle hinge flap would be ideal. The procedure was performed on the mobile veterinary unit and managed postoperatively with pain control and biweekly bandage changes. After 3 weeks, the single-pedicle hinge flap was released to create a skin graft, which successfully filled the defect. Relevance and novel information Single-pedicle hinge flaps performed in feline patients have been minimally reported. This case report serves to provide detailed information on the surgical procedure and aftercare required for a successful outcome. Furthermore, this procedure was performed by a shelter medicine team in a mobile veterinary unit with no specialty equipment or instruments. This report documents an alternative procedure that may be used in a shelter environment for distal forelimb wounds rather than amputation or euthanasia.

    Forensic investigations in dog attacks usually involve the examination of bite marks and toothprints, the dog's stomach and pathological methods. For identification of the offending dog we evaluated canine STR typing of saliva traces on dog bite marks. The specificity of 15 canine-specific STRs was tested on human-canine DNA mixtures prior to an applied study in which 52 cases of dog bites were investigated. The first-aid wound bandages as well as swab samples from the surrounding area of the wound were used for DNA analyses. Generally, it was possible to obtain a canine-specific STR profile from the dog's saliva left on the wound area, even when high background of human DNA was present (blood). Interestingly, we found canine STR typing to be more successful when the bandages and swabs showed high amounts of human blood, i.e. when the dog bite was severe. Canine saliva was then sometimes visible as white-coloured secretion on the human blood surface. Less severe bite cases, which did not result in bleeding wounds, showed less success in obtaining useful STR results, probably due to the fact that the surface of the wounds may have been treated before the victims consulted medical aid which therefore removed the canine cells.

    This research was aimed to find the skin irritation and burns treatment effect of wound dressing with mi- crospheres containing levofloxacin. We used reference GB/T16886. 10-2005 to evaluate the dressing skin irritation. We prepared rabbit models divided into three groups. The control group was rapped with Vaseline gauze bandage, while the positive control group was rapped with the wounds of nano-silver paste bandage. The experimental sample group was rapped with wound dressing with microspheres containing levofloxacin. We measured the wound without healing area and the hydroxyproline content at the ends of 3 d, 6 d, 9 d, 14 d, 21 d, 28 d. and meanwhile performed histopathological examination. The experimental results showed that the dressing primary irritation index was 0. The nonhealing wound area of theexperimental sample group and positive control group at the ends of 6 d, 9 d, 14 d, 21 d were less than that of the control group (Pdressing with microspheres containing levofloxacin has minimal skin irritation, effectively promote wound healing of burn.

    2012-11-01

    A 4-month-old Standardbred colt was examined because of a fractured right calcaneus of 8 days' duration with increased distraction of the fracture fragment evident on sequential radiographs. The foal was severely lame with diffuse periarticular tarsal swelling. Radiographically, a complete, displaced long oblique fracture of the right calcaneal body was evident. Because the fracture gap was increasing with time and lameness remained severe, despite medical management, surgical repair was recommended. The foal was anesthetized, and minimally invasive fracture reduction and internal fixation were achieved by use of two 4.5-mm cortical screws placed in lag fashion via stab incisions over the lateral aspect of the calcaneus. External coaptation with a Robert-Jones bandage only was used after surgery. The foal recovered well and the fracture healed appropriately, but at 8 weeks following surgery, tenosynovitis of the tarsal sheath had developed. This was attributed to the tip of the distal screw encroaching on the sheath. The screw was removed under anesthesia and the tarsal sheath drained. The tenosynovitis resolved with rest and bandaging. Fourteen months after surgery, the colt was free of lameness. Findings suggested that a minimally invasive internal fixation technique for treatment of a calcaneus fracture in horses may be successful and may be associated with decreased morbidity, compared with the use of open reduction and plate fixation.

    2010-01-01

    Full Text Available Vascular glycosaminoglycans (GAG are essential components of the endothelium and vessel wall and have been shown to be involved in several biologic functions. Mesoglycan, a natural GAG preparation, is a polysaccharide complex rich in sulphur radicals with strong negative electric charge. It is extracted from porcine intestinal mucosa and is composed of heparan sulfate, dermatan sulfate, electrophoretically slow-moving heparin, and variable and minimal quantities of chondroitin sulfate. Data on antithrombotic and profibrinolytic activities of the drug show that mesoglycan, although not indicated in the treatment of acute arterial or venous thrombosis because of the low antithrombotic effect, may be useful in the management of vascular diseases, when combined with antithrombotics in the case of disease of cerebral vasculature, and with antithrombotics and vasodilator drugs in the case of chronic peripheral arterial disease. The protective effect of mesoglycan in patients with venous thrombosis and the absence of side effects, support the use of GAG in patients with chronic venous insufficiency and persistent venous ulcers, in association with compression therapy (zinc bandages, multiple layer bandages, etc., elastic compression stockings, and local care, and in the prevention of recurrences in patients with previous DVT following the standard course of oral anticoagulation treatment.

    To report a technique for laser-facilitated, minimally invasive proximal interphalangeal joint (PIJ) arthrodesis in horses. Case series. Horses (n=6); 5 thoracic and 2 pelvic limb PIJ. PIJ osteoarthritis (OA) diagnosis was confirmed by radiography. A diode laser was used to apply 2000 J of energy to the joint followed by insertion of 3 parallel 5.5 mm screws in lag fashion through stab incisions to achieve PIJ arthrodesis. After anesthetic recovery, limbs were maintained in bandages (n=2) or bandage casts (5) for 3 weeks. Horses were allowed exercise or turnout by 3 months. Three horses (4 limbs) were sound throughout follow-up (6-18 months). One horse remained lame the 1st month, another had mild lameness at pasture at 6 weeks, and another had persistent low-grade lameness and delayed joint fusion (1 year). Within 6 months, 5 horses were sound, 4 had radiographic evidence of successful joint fusion, and 5 had returned to intended use. Diode laser-facilitated, 3 parallel screw arthrodesis for PIJ OA costs less and is associated with less pain compared with standard, open PIJ arthrodesis using 3 parallel screws inserted in lag fashion. In horses with advanced PIJ OA, this technique appears to be a viable alternative for PIJ arthrodesis. Further study including characterization of the effects of the laser, ideal case selection indications, and optimal laser dose is indicated before this technique is recommended for routine PIJ arthrodesis.

    To analyze the cause and effect of magnet dislocation in cochlear implant (CI) recipients requiring magnet revision surgery for treatment. Retrospective study. Tertiary referral center. Case reports from 1,706 CI recipients consecutively implanted from January 2000 to December 2011 were reviewed. The number of cases requiring magnet revision surgery was assessed. Revision surgery involving magnet removal or replacement was indicated in 1.23% (21/1,706), of all CI recipients. Magnet dislocation occurring during magnetic resonance tomography (MRI), at 1.5 Tesla (T), with the magnet in place and with the application of compression bandaging around the head, was the main cause for revision surgery in 47.62% (10/21) of the affected cases. All 10 cases were implanted with Cochlear Nucleus cochlear implants. These events occurred, despite adherence to current recommendations of the manufacturer. The present study underlines that MRI examination is the main cause of magnet dislocation. The use of compressive bandaging when using 1.5-T MRI does not eliminate the risk of magnet dislocation. Additional cautionary measures are for required for conditional MRI. We recommend X-ray examination after MRI to determine magnet dislocation and avoid major complications in all cases reporting pain during or after MRI. Additional research regarding silicon magnet pocket design for added retention is needed. Effective communication of guidelines for precautionary measures during MRI examination in CI patients is mandatory for all clinicians involved. MRI in CI recipients should be indicated with caution.

    To determine effects of extracorporeal shock wave therapy (ESWT) on healing of wounds in the distal portion of the forelimb in horses. 6 horses. Five 6.25-cm2 superficial wounds were created over both third metacarpi of 6 horses. Forelimbs were randomly assigned to treatment (ESWT and bandage) or control (bandage only) groups. In treated limbs, each wound was treated with 625 shock wave pulses from an unfocused electrohydraulic shock wave generator. In control limbs, each wound received sham treatment. Wound appearance was recorded weekly as inflamed or healthy and scored for the amount of protruding granulation tissue. Standardized digital photographs were used to determine the area of neoepithelialization and absolute wound area. Biopsy was performed on 1 wound on each limb every week for 6 weeks to evaluate epithelialization, fibroplasia, neovascularization, and inflammation. Immunohistochemical staining for A smooth muscle actin was used to label myofibroblasts. Control wounds were 1.9 times as likely to appear inflamed, compared with treated wounds. Control wounds had significantly higher scores for exuberant granulation tissue. Treatment did not affect wound size or area of neoepithelialization. No significant difference was found for any of the histologic or immunohistochemical variables between groups. Treatment with ESWT did not accelerate healing of equine distal limb wounds, but treated wounds had less exuberant granulation tissue and appeared healthier than controls. Therefore, ESWT may be useful to prevent exuberant granulation tissue formation and chronic inflammation of such wounds, but further studies are necessary before recommending ESWT for clinical application.

    Olecranon bursitis might be a minor problem in the outpatient clinic but relatively be common to occur. However, there are few well-designed studies comparing approaches to treatment. (1) Which treatment (compression bandaging with nonsteroidal antiinflammatory drugs [NSAIDs], aspiration, or aspiration with steroid injections) is associated with the highest likelihood of resolution of nonseptic olecranon bursitis? (2) Which treatment is associated with earliest resolution of symptoms? (3) What factors are associated with treatment failure by 4 weeks? We enrolled 133 patients from two centers; after applying prespecified exclusions (septic bursitis or concomitant inflammatory arthritis, intraarticular elbow pathology, recent aspiration or steroid injection done elsewhere, and refusal to participate), 90 patients were randomly allocated to receive compression bandaging with NSAIDs (C), aspiration (A), or aspiration with steroid injection (AS) groups (30 patients in each). The groups were similar at baseline in terms of age and gender. Seven patients (four from Group A and three from Group AS) were lost to followup. All patients were followed up weekly for 4 weeks, and the same treatment procedure was repeated if the bursitis recurred with any substantial fluid collection. At 4 weeks, the state of resolution and pain visual analog scale (VAS) were evaluated. Failed resolution was defined as presence of persistent olecranon bursal fluid collection at Week 4 after the initiation of the treatment; on the contrary, if bursal fluid collection was clinically reduced or completely disappeared by the end of Week 4, the treatment was considered successful. We compared the proportion of resolution by Week 4 and the median times to resolution among the treatment groups. In addition, we evaluated whether the resolution affected pain VAS and what factors were associated with the resolution. There were no differences in the proportion of patients whose bursitis resolved by Week 4

    One of the recommended treatments for disorders associated with the lower extremity venous insufficiency is the application of external mechanical compression. Compression stockings and elastic bandages are widely used for the purpose of compression therapy and are usually designed to exert a specified value or range of compression on the leg. However, the leg deforms under external compression, which can lead to undesirable variations in the amount of compression applied by the compression bandages. In this paper, the use of an active compression bandage (ACB), whose compression can be regulated through an electrical signal, is investigated. The ACB is based on the use of dielectric elastomer actuators. This paper specifically investigates, via both analytical and non-linear numerical simulations, the potential pressure the ACB can apply when the compliancy of the human leg is taken into account. The work underpins the need to account for the compressibility of the leg when designing compression garments for lower extremity venous insufficiency. A mathematical model is used to simulate the volumetric change of a calf when compressed. Suitable parameters for this calf model are selected from the literature where the calf, from ankle to knee, is divided into six different regions. An analytical electromechanical model of the ACB, which considers its compliancy as a function of its pre-stretch and electricity applied, is used to predict the ACB's behavior. Based on these calf and ACB analytical models, a simulation is performed to investigate the interaction between the ACB and the human calf with and without an electrical stimulus applied to the ACB. This simulation is validated by non-linear analysis performed using a software based on the finite element method (FEM). In all simulations, the ACB's elastomer is stretched to a value in the range between 140 and 220 % of its initial length. Using data from the literature, the human calf model, which is examined in

    Up to 1% of adults will have a leg ulcer at some time. The majority of leg ulcers are venous in origin and are caused by high pressure in the veins due to blockage or weakness of the valves in the veins of the leg. Prevention and treatment of venous ulcers is aimed at reducing the pressure either by removing/repairing the veins, or by applying compression bandages/stockings to reduce the pressure in the veins.The majority of venous ulcers heal with compression bandages, however ulcers frequently recur. Clinical guidelines therefore recommend that people continue to wear compression, usually in the form of hosiery (tights, stockings, socks) after their ulcer heals, to prevent recurrence. To assess the effects of compression (socks, stockings, tights, bandages) in preventing the recurrence of venous ulcers. If compression does prevent ulceration compared with no compression, then to identify whether there is evidence to recommend particular levels of compression (high, medium or low, for example), types of compression, or brands of compression to prevent ulcer recurrence after healing. For this second update we searched The Cochrane Wounds Group Specialised Register (searched 4 September 2014) which includes the results of regular searches of MEDLINE, EMBASE and CINAHL; The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2014, Issue 8). Randomised controlled trials (RCTs)evaluating compression bandages or hosiery for preventing the recurrence of venous ulcers. Two review authors undertook data extraction and risk of bias assessment independently. Four trials (979 participants) were eligible for inclusion in this review. One trial in patients with recently healed venous ulcers (n = 153) compared recurrence rates with and without compression and found that compression significantly reduced ulcer recurrence at six months (Risk ratio (RR) 0.46, 95% CI 0.27 to 0.76).Two trials compared high-compression hosiery (equivalent to UK class 3) with

    Leg ulcers usually occur secondary to venous reflux or obstruction, but 20% of people with leg ulcers have arterial disease, with or without venous disorders. Between 1.5 and 3.0/1000 people have active leg ulcers. Prevalence increases with age to about 20/1000 in people aged over 80 years. We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of standard treatments, adjuvant treatments, and organisational interventions for venous leg ulcers? What are the effects of advice about self-help interventions in people receiving usual care for venous leg ulcers? What are the effects of interventions to prevent recurrence of venous leg ulcers? We searched: Medline, Embase, The Cochrane Library, and other important databases up to June 2011 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA). We found 101 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions. In this systematic review we present information relating to the effectiveness and safety of the following interventions: compression bandages and stockings, cultured allogenic (single or bilayer) skin replacement, debriding agents, dressings (cellulose, collagen, film, foam, hyaluronic acid-derived, semi-occlusive alginate), hydrocolloid (occlusive) dressings in the presence of compression, intermittent pneumatic compression, intravenous prostaglandin E1, larval therapy, laser treatment (low-level), leg ulcer clinics, multilayer elastic system, multilayer elastomeric (or non-elastomeric) high-compression regimens or bandages, oral treatments (aspirin, flavonoids, pentoxifylline, rutosides, stanozolol, sulodexide

    An ulcerative dermopathy caused by Mycobacterium ulcerans is described in two alpacas (Vicugna pacos) domiciled in endemic areas of Victoria, Australia. The diagnosis was confirmed in both cases by PCR targeting the M. ulcerans-specific insertion sequence, IS2404. Extensive wound debridement and bandaging was effective in controlling local disease in one alpaca, although the animal was eventually euthanased because of suspected disease recurrence at other anatomical sites. Treatment was not undertaken in the second animal, but the results of a complete necropsy are described. Investigation of the environs of the second animal yielded low levels of M. ulcerans DNA associated with a variety of samples. The potential use of adjunctive antibiotic therapies directed against M. ulcerans infection in this species is discussed. Mycobacterium ulcerans infection should be suspected in alpacas domiciled in endemic areas and presented with ulcerative skin disease. © 2013 The Authors.

    Development of new generation bionanotextiles is an important growing field, and they have found applications as wound dressings, bandages, tissue scaffolds, etc. In this study, silver nanoparticle (AgNP) containing silk-based bionanotextiles were fabricated by electrospinning, and processing parameters were optimized and discussed in detail. AgNPs were in situ synthesized within fibroin nanofibers by UV reduction of silver ions to metallic silver. The influence of post-treatments via methanol treatment and glutaraldehyde (GA) vapor exhibited changes in the secondary structure of silk. Methanol treatment increased the tensile properties of fibers due to supported crystalline silk structure, while GA vapor promoted amorphous secondary structure. AgNP containing silk fibroin bionanotextiles had strong antibacterial activity against gram-positive Staphylococcus aureus and gram-negative Pseudomonas aeruginosa.

    We evaluated a miniaturized digital and electronic tonometer, the Tono-Pen, for accuracy of intraocular pressure measurement in the presence of a contact lens. In the manometric study, the Tono-Pen was used to measure a known intraocular pressure, ranging from 10 mm Hg to 60 mm Hg in a cadaver eye over soft contact lenses with different powers and a plano-T bandage lens. There was significant bias in pressure measurement over all contact lenses except for the plano-T, which had no bias at any level. In the clinical study, the intraocular pressures of 40 eyes in 20 normal patients were measured with and without a plano-T contact lens in place. Analysis of variance showed no significant interactive effect between the right and left eyes, with or without the lens. There was no significant difference in the Tono-Pen measurement of intraocular pressure over a plano-T contact lens compared with no lens.

    Radiation treatments using low energy X-rays or electrons frequently require a final field defining shield to be placed on the patient's skin. A custom made lead cut-out is used to provide a close fit to a particular patient's surface contours. We have developed a procedure which utilizes POLYFORM thermoplastic to obtain a negative mold of the patient instead of the traditional plaster bandage or dental impression gel. The Polyform is softened in warm water, molded carefully over the patient's surface, and is removed when set or hardened, usually within five minutes. Then lead sheet cut-outs can be formed within this negative. For shielding cut-outs requiring thicker lead sheet, a positive is made from dental stone using this Polyform negative. We have found this procedure to be neat, fast and comfortable for both patient and the dosimetrist

    within the last two centuries. However, the historical preconditions for this development have not been studied. This paper reviews written sources from the fall of the Roman Empire to the late eighteenth century. Medieval and early modern writers mainly rely on the Hippocratic writings De Fracturis...... and De Articulationes. The Hippocratic account of the normal anatomy of the shoulder reveals some biomechanical insights. However, knowledge of bone and joint anatomy of the shoulder useful for surgical purposes is not found in medieval sources. Even in fourteenth century illustrations based on human......, and Vesalius (1514-1564) gives a systematic account for the osteology and myology of the shoulder. In early eighteenth century, the Hippocratic approach is challenged and more gentle modes of reduction and bandaging are proposed. Desault (1744-1795) gives an account of the muscle traction responsible...

    Rehabilitation gloves are equipment that helps rehabilitation doctors perform finger rehabilitation training, which can greatly reduce the labour intensity of rehabilitation doctors and make more people receive finger rehabilitation training. In the light of the defects of the existing rehabilitation gloves such as complicated structure and stiff movement, a rehabilitation mechanical glove is designed, which provides driving force by using the air cylinder and adopts a rope-spring mechanism to ensure the flexibility of the movement. In order to fit the size of different hands, the bandage ring which can adjust size is used to make the mechanism fixed. In the interest of solve the complex problem of dynamic equation, dynamic simulation is carried out by using Adams to obtain the motion curve, which is easy to optimize the structure of ring position.

    Dislocation of the shoulder is the commonest of all large joint dislocations. Inferior dislocation constitutes 0.5% of all shoulder dislocations. It characteristically presents with overhead abduction of the arm, the humerus being parallel to the spine of scapula. We present an unusual case of recurrent luxatio erecta in which the arm transformed later into an adducted position resembling the more common anterior shoulder dislocation. Such a case has not been described before in English literature. Closed reduction by the two-step maneuver was successful with a single attempt. MRI revealed posterior labral tear and a Hill-Sachs variant lesion on the superolateral aspect of humeral head. Immobilisation in a chest-arm bandage followed by physiotherapy yielded excellent results. The case is first of its kind; the unusual mechanism, unique radiological findings and alternate method of treatment are discussed. PMID:19883514

    This article presents a case study of a patient who was treated for 5 years from the time of diagnosis until his death. The patient was diagnosed with familial polyposis at the age of 35 due to a family history of the same. He suffered from low body image and showed a poor response to treatment, especially regarding nutrition. The period of time related to the presentation of symptoms and the patient's subsequent deterioration was characterized by attempts on the part of nursing staff to improve the patient's quality of life. Treatment of multiple fistulae was employed, while keeping the skin intact, along with the creative development of a unique bandaging method. This article describes the course of the patient's disease and specifies his problems and their solutions. It is hoped that presentation of this case will benefit caregiving staff in dealing with similar cases.

  9. Respiration rate detection based on intensity modulation using plastic optical fiber

    2017-01-01

    Full Text Available This paper presents the implementation of respiration rate measurement via a simple intensity-based optical fiber sensor using optical fiber technology. The breathing rate is measured based on the light intensity variation due to the longitudinal gap changes between two separated fibers. In order to monitor the breathing rate continuously, the output from the photodetector conditioning circuit is connected to a low-cost Arduino kit. At the sensing point, two optical fiber cables are positioned in series with a small gap and fitted inside a transparent plastic tube. To ensure smooth movement of the fiber during inhale and exhale processes as well as to maintain the gap of the fiber during idle condition, the fiber is attached firmly to a stretchable bandage. This study shows that this simple fiber arrangement can be applied to detect respiration activity which might be critical for patient monitoring.

    Prosthetic replacement of the ocular surface ecosystem is a treatment developed by the Boston Foundation for Sight that uses a Food and Drug Administration-approved prosthetic device for the treatment of severe ocular surface disease to improve vision and discomfort in addition to supporting the ocular surface. Facial nerve paralysis has multiple causes including trauma, surgery, tumor, stroke, and congenital lagophthalmos. Subsequent lagophthalmos leading to exposure keratitis has been treated with copious lubrication, tarsorrhapy, eyelid weights, chemodenervation to yield protective ptosis, and palpebral spring insertion. Each of these treatments, however, has limitations and potential complications. The prosthetic replacement of the ocular surface ecosystem device provides a liquid bandage to protect the cornea from eyelid interaction and dessication in addition to improving vision. This report describes 4 patients with exposure keratitis who were successfully treated with prosthetic replacement of the ocular surface ecosystem devices at 2 clinical sites.

    Full Text Available The article describes the clinical case of an infant with Bruck syndrome. The clinical and radiological analyses showed the presence of systemic osteoporosis with pathological fractures; contractures of the elbow, knee, and ankle joints; delay of physical and motor development; and signs of hypoplasia in some of the muscle groups. There was also a right-sided congenital muscular torticollis. X-ray analysis revealed a moderate antecurvation deformity of the lower legs and femurs, with cortical thinning. Laboratory data detected an abnormal beta-cross lap increase.Treatment of osteoporosis by inhibitors of osteoclastic resorption (pamidronate had a positive effect, and the elimination of flexion contractures at the elbow using plaster bandages with the distraction device also resulted in a positive effect.

    To define the extent of Senior First Aid training in a sample of the Western Australian community, and to evaluate the effect of previous training on first aid knowledge and skills. A telephone survey of a random sample from suburban Perth and rural Western Australia; and practical assessment of first aid skills in a subsample of those surveyed. 30.4% of respondents had completed a Senior First Aid certificate. Trained individuals performed consistently better in theoretical tests (p=0.0001) and practical management of snakebite (p=0.021) than untrained. However, many volunteers, both trained and untrained, demonstrated poor skills in applying pressure immobilisation bandaging and splinting the limb adequately despite electing to do so in theory. Overall knowledge and performance of first aid skills by the community are poor, but are improved by first aid training courses.

    Case A 30‐year‐old woman had her left thigh run over by a train. We tried to compress the left femoral area to control the arterial bleeding, but bleeding continued from the stump and injured soft tissue. The application of a tourniquet bandage also failed because of the limited remaining thigh. She developed impending cardiac arrest. As the left femoral arterial pulsation was still palpable, we inserted an intra‐aortic balloon occlusion catheter percutaneously. The hemorrhage from the stump region decreased rapidly. She was transferred to an operating room to carry out surgical hemostasis, and it was confirmed with deflation of the balloon in the common iliac artery. Outcome There was no complication of the skin or soft tissue at the surgical site caused by impaired circulation, and her consciousness fully recovered. Conclusion We report the successful control of bleeding by the emergently modified application of intra‐aortic balloon occlusion in the left common iliac artery. PMID:29123695

    2016-01-01

    This case study describes treatment for a 52-year-old man with a recurrent venous leg ulcer using a collagen dressing with extracellular matrix. The patient was admitted to the wound care service for a 3-week-old recurrent venous ulcer. Treatment included application of a collagen dressing with extracellular matrix twice weekly or as needed by the patient; application of a secondary dressing (4 × 4 gauze); and coverage with an expandable netting or gauze using a conforming stretch gauze bandage and latex-free dressing retention tape. The initial venous leg ulcer in this patient required 10 weeks to achieve closure. Ninety-eight percent resolution of the recurrent ulcer had occurred within 4 weeks of treatment, with complete closure at 7 weeks. The average healing time for recurrent venous ulcers is reported in the literature to be longer than initial venous ulcers. In the case provided, collagen ECM dressings promoted complete wound healing in 49 days.

    Venous leg ulcers are the most frequent form of wounds seen in patients. This article presents an overview on some practical aspects concerning diagnosis, differential diagnosis and treatment. Duplex ultrasound investigations are essential to ascertain the diagnosis of the underlying venous pathology and to treat venous refluxes. Differential diagnosis includes mainly other vascular lesions (arterial, microcirculatory causes), hematologic and metabolic diseases, trauma, infection, malignancies. Patients with superficial venous incompetence may benefit from endovenous or surgical reflux abolition diagnosed by Duplex ultrasound. The most important basic component of the management is compression therapy, for which we prefer materials with low elasticity applied with high initial pressure (short-stretch bandages and Velcro-strap devices). Local treatment should be simple, absorbing and not sticky dressings keeping adequate moisture balance after debridement of necrotic tissue and biofilms are preferred. After the ulcer is healed compression therapy should be continued in order to prevent recurrence. PMID:26236636

    2013-01-01

    Fractures of the proximal humerus have been diagnosed and managed since the earliest known surgical texts. For more than four millennia the preferred treatment was forceful traction, closed reduction, and immobilization with linen soaked in combinations of oil, honey, alum, wine, or cerate....... The bandages were further supported by splints made of wood or coarse grass. Healing was expected in forty days. Different fracture patterns have been discussed and classified since Ancient Greece. Current classification of proximal humeral fractures mainly relies on the classifications proposed by Charles...... Neer and the AO/OTA classification. Since the late 1980's it has been known that intra- and inter-observer variation was high within the two systems. I conducted a series of observer studies to qualify the disagreement further and to study to what extent improvement of agreement could be obtained...

  19. Rehabilitation treatment in children with scoliosis

    International Nuclear Information System (INIS)

    Fonseca, Galia

    1998-01-01

    The scoliosis is classified as the problem more common of the spinal cord in the pediatric population. It is defined like a lateral abnormal bend of the spinal cord. It exists a wide range of unique or combined interventions that they will guarantee that the bend in most of the cases remains stable and in others that it diminishes until the period of the boy's growth is completed. The election of the type of intervention observation, orthesis, bandage in plaster or surgical it will depend on the skeletal maturity and of the classification that is made of the scoliosis. Every time that the intervention begins in a patient with scoliosis an individual analysis of each situation should be carried out, for this reason the rehabilitation services have an interdisciplinary team that looks for, above all, the execution of the elected treatment. The paper includes physical exam, methods and intervention types

    Traditional circumcision (initiation) is an integral part of the Xhosa speaking communities. Circumcision is the first step towards manhood. It involves a number of cultural, religious, legal and ethical issues, which in terms of the constitution of the Republic of South Africa, are rights that must be protected. To highlight the problem of circumcision related death in South Africa. This case report examines a 16- year boy who had died as result of botched circumcision by an unqualified traditional surgeon. He kept the boy in his custody despite his serious illness. He applied a tight bandage to control the bleeding, resulting in gangrene of the penis followed by septicemia. The histories, postmortem findings, cause of death and medico- legal and social aspects have been discussed in this manuscript. There are unacceptable deaths related with circumcision in South Africa. The right to life cannot be sacrificed at the altar of culture and politics.

    Scleral lenses are large diameter lenses which rest over the sclera, unlike the conventional contact lenses which rest on the cornea. These lenses are fitted to not touch the cornea and there is a space created between the cornea and the lens. These lenses are inserted in the eyes after filling with sterile isotonic fluid. Generally, scleral contact lenses are used for high irregular astigmatism as seen in various corneal ectatic diseases such as keratoconus, pellucid marginal degeneration, or/and as liquid bandage in ocular surface disorders. In this article, we review the new developments, that have taken place over the years, in the field of scleral contact lenses as regard to new designs, materials, manufacturing technologies, and fitting strategies particularly for keratoconus.

    Full Text Available A 19-year-old male subject was diagnosed with medial meniscal, lateral meniscal and anterior cruciate ligament (ACL tear. The symptoms did not subside after 4 months of physical therapy, and he underwent arthroscopic partial medial and lateral meniscectomy and ACL reconstruction. Immediately after the patient woke up from general anesthesia, he started experience loss of sensation in the area of superficial peroneal nerve with inverted dorsiflexion of foot and ankle. Instantly, the bandage and knee brace was removed and a diagnosis of compartment syndrome was ruled out. After eight hours, post-operatively, the patient started receiving physiotherapy. He complained of numbness and tingling in the same area. After 24 h, post-operatively, the patient started to regain dorsiflexion and eversion gradually. Two days after the surgery, the patient exhibited complete recovery of neurological status.

    Addressing pressure reduction in the treatment of diabetic foot wounds is a critical component of therapy. The total-contact cast has proven to be the gold standard of treatment because of its ability to reduce pressure and facilitate patient adherence to the off-loading regimen. Removable cast walkers have proven to be as effective as total-contact casts in pressure reduction, but this has not translated into equivalent time to healing. A simple technique to convert the removable cast walker into a device that is not as easily detached from the lower extremity, thereby encouraging the use of this device over a 24-hour period, is presented in this article. The procedure involves wrapping the cast walker with cohesive bandage or plaster of Paris. In the authors' opinion, this technique addresses many of the disadvantages of the total-contact cast, resulting in an adequate compromise in this aspect of care.

    Introduction: The use of lasers has become a practice in modern periodontology and it is a fact that the use of diodes in the dental office can bring a real benefit in periodontal surgery. Material and method: These case reports describe few of various soft tissue procedures that were performed with diode laser 940 nm (Epic 10, Biolase Inc., USA). Discussions: There are a few immediate benefits of the intervention: the "periodontal bandage" belongs to the patient, the procedure is painless, performed under a superficial anesthesia and the psychological impact on the patient, as well as the acceptance, are superior to conventional methods of dentistry. Conclusions: Diode lasers at the level of periodontium have become a significant part of the dentistry, reducing the patient's stress and giving satisfaction to practitioners as well.

    The development of low temperature, thin film transistor processes that have enabled flexible displays also present opportunities for flexible electronics and flexible integrated systems. Of particular interest are possible applications in flexible sensor systems for unattended ground sensors, smart medical bandages, electronic ID tags for geo-location, conformal antennas, radiation detectors, etc. In this paper, we review the impact of gate dielectrics, contacts and semiconductor materials on thin film transistors for flexible electronics applications. We present our recent results to fully integrate hybrid complementary metal oxide semiconductors comprising inorganic and organic-based materials. In particular, we demonstrate novel gate dielectric stacks and semiconducting materials. The impact of source and drain contacts on device performance is also discussed.

    Lipedema is a disproportional obesity for which evidence-based treatment is not currently available. We studied whether complete decongestive physiotherapy (CDP) alone or combined with intermittent pneumatic compression (IPC) could improve the treatment outcome in women with lipedema using a prospective, randomized trial. Eleven patients received CDP (60 min) and thirteen CDP (30 min) plus IPC (30 min) once daily in a 5-day-course. Subsequent to drainage, all subjects received multilayered compression bandaging, physical exercise and skin care. Treatment efficacy was evaluated by limb volume reduction. Both groups achieved significant reductions in mean lower extremity volume (p < 0.05). The addition of IPC is safe, although it provides no synergistic benefit to CDP in leg volume reduction under these study conditions.

  10. Raising the four downcomers in the reactor aluminium tank of the FRJ-2 research reactor as an example of the execution of complicated work in the region of high radiation levels

    As a result of the planned power increase from 15 MW to 25 MW, a new emergency cooling system had to be installed in the research reactor FRJ-2 of the KFA Juelich, which called for an extension of the four standpipes in the reactor tank by 57 mm. Due to the high radiation level in the reactor tank, new techniques had to be found allowing aluminium rings of corresponding height to be welded onto the top part of the standpipes by remotecontrolled welding; moreover, the welded parts were then to be protected by a bandage made of high-quality steel. The development work was carried out in the KFA and this report gives an account of the technique applied and the results obtained. (author)

    To provide insight into the clinical anatomy of Tenon's capsule and to describe a technique to manage sclerocorneal defects using autologous Tenon's tissue. A thin layer of Tenon's capsule harvested from the patient's own eye is used to seal the defect and act as a scaffold. The Tenon's flap is spread over the defect and held in place by Vicryl sutures. A bandage contact lens is then placed on the eye. Tenon's capsule is composed of thick fibrous tissue with smooth muscle fibers and a thin posterior capsule of orbital fat. It is rich in fibroblasts, which can accelerate wound healing and eventually lead to robust scarring without risk of immunogenicity and without cost. Tenonplasty uses easily-available autologous Tenon's tissue in patients with sclerocorneal defects to preserve globe morphology. The technique is a feasible alternative not limited by the availability of graft tissue. Clin. Anat. 31:72-76, 2018. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    Negative-pressure hydrocephalus (NegPH), a very rare condition of unknown etiology and optimal treatment, usually presents postneurosurgery with clinical and imaging features of hydrocephalus, but with negative cerebrospinal fluid pressure. We describe a NegPH case of -3 mm Hg intracranial pressure that was successfully treated to achieve 5 mm Hg under continuous intracranial pressure monitoring with horizontal positioning, head down and legs elevated to 10°-15°, neck wrapping for controlled venous drainage, chest and abdomen bandages, infusion of 5% dextrose fluid to lower plasma osmolarity (Na + , 130-135 mmol/L), daily cerebrospinal fluid drainage >200 mL, and arterial blood gas partial pressure of carbon dioxide >40 mm Hg.

    This work presents the multidisciplinary investigation of the head of Nebiri (Museo Egizio, Turin S_5109), Chief of Stables, a high status elite person from the 18th Dynasty involving MDCT, 3D brain surface and facial reconstructions accompanied by a consideration of previously presented chemical analysis of the embalming materials found in fragments of bandages used on the head and viscera (lung) found in one of the four canopic jars. Comparison of the techniques used for the cosmetic treatment of Nebiri with those used in other elite and high status non-royal persons confirms the validity of the use of the term "high status elite" in the case of Nebiri. This case highlights the importance of using modern forensic techniques both to enhance new technologies of retrospective diagnosis on altered human remains and to increase knowledge of past populations.

    Lymphedema resulting from fluid accumulation due to impairment in the lymphatic system drainage leads to enlargement of the body part involved. If left untreated, in its third stage it results in elephantiasis. Elephantiasis is frequently accompanied by papillomatosis and lymphocutaneous fistulas with lymphorrhoea, erosions and ulcers, frequently with the loss of function in the respective part of the body. Unlike other chronic wounds, wound healing in lymphedema is highly dependent on the use of combined therapies because local treatment with modern supportive dressings and compression therapy with adhesive and non-adhesive short-stretch systems is only part of the complete treatment. This treatment also includes sub-bandage foamy materials, kinesitherapy with tapes (kinesiotaping), intermittent local application of high-pressure oxygen, breathing exercise, and manual lymph drainage and exercises.

    The current report describes the temporary regression, due to intensive symptomatic treatment, of ulcerative skin lesions caused by squamous cell carcinoma in a white rhinoceros. A captive, 40-yr-old southern white rhinoceros (Ceratotherium simum simum) developed profound, ulcerative skin lesions on the pads of both hind feet. At the peak of the disease, at least one quarter of the pads was affected. A diagnosis of squamous cell carcinoma was made via biopsy. Treatment included anti-inflammatory drugs, antibiotics, and local care. The lesions regressed on both feet until they seemed clinically healed. It was presumed that long-term, anti-inflammatory treatment and local bandaging had induced the temporary regression of the lesions. Two years later, however, a small ulcerative lesion reappeared on one pad and post mortem examination confirmed that the carcinoma was also histologically present in the clinically intact tissue. No metastasis was found and computed tomography showed normal digital bones.

    The goal of this report is to describe the therapeutic methods and surgical techniques used by Hippocrates (5th century BC) in the treatment of nasal injuries. We studied the original Greek texts of the (generally considered genuine) Hippocratic book Mochlicon and, especially, the analytical On Joints. We identified the treatments and techniques applied to the restoration of injured noses. We found that Hippocrates classified nasal injuries, from simple contusions of soft tissues to complicated fractures. Hippocrates provided detailed instructions for each case, from poultice application and bandaging to reconstruction and reshaping of the nasal bones in cases of fractures and deviation. Hippocrates' texts reflect the interest of the classical period in nasal injuries, a common enough accident in athletics. Hippocratic conservative and surgical management for each form of injury was adopted by later physicians and influenced European medicine.

  19. Controversies in venous thromboembolism: to treat or not to treat superficial vein thrombosis.

    Science.gov (United States)

    Beyer-Westendorf, Jan

    2017-12-08

    The management of superficial vein thrombosis (SVT) is poorly defined and remains controversial overall. SVT has long been considered a benign, self-limited disease, but recent studies show that SVT carries a nonnegligible risk for recurrence, deep vein thrombosis, or pulmonary embolism. Current guidelines recommend the use of low-molecular-weight heparin or fondaparinux, but results of several surveys indicate that the majority of patients with SVT receive nonanticoagulant therapy only, which includes compression stockings or bandages, nonsteroidal anti-inflammatory drugs, topical application of heparin gel, or surgical interventions. However, several recent observational and interventional studies provide better insight into the optimal treatment of patients with SVT who are at different risks for thromboembolic complications. This educational review summarizes the available evidence and aims to provide practical guidance based on a clinical decision pathway. © 2016 by The American Society of Hematology.

    Superficial vein thrombosis (SVT) was considered to be a benign and self-limiting condition. However, it is now appreciated that a significant proportion of those presenting with SVT will have concomitant deep vein thrombosis or pulmonary embolism, or are at significant risk of developing deep venous thromboembolism. Potential therapeutic options include topical preparations, compression therapy (stockings, bandages), medication such as non-steroidal anti-inflammatory drugs (NSAIDs) or anticoagulants (therapeutic or prophylactic doses) and surgery, ligation or stripping, of superficial veins. The treatment of choice is therapeutic/intermediate dose low molecular weight heparin or prophylactic dose fondaparinux administered for 4-6 weeks. The cost-effectiveness of treatment is a concern and more targeted therapy is required. © 2014 John Wiley & Sons Ltd.

    Full Text Available Abstract Dislocation of the shoulder is the commonest of all large joint dislocations. Inferior dislocation constitutes 0.5% of all shoulder dislocations. It characteristically presents with overhead abduction of the arm, the humerus being parallel to the spine of scapula. We present an unusual case of recurrent luxatio erecta in which the arm transformed later into an adducted position resembling the more common anterior shoulder dislocation. Such a case has not been described before in English literature. Closed reduction by the two-step maneuver was successful with a single attempt. MRI revealed posterior labral tear and a Hill-Sachs variant lesion on the superolateral aspect of humeral head. Immobilisation in a chest-arm bandage followed by physiotherapy yielded excellent results. The case is first of its kind; the unusual mechanism, unique radiological findings and alternate method of treatment are discussed.

    We present a case of an 80-year-old male who was referred to the Department of Oral Medicine, School of Dental Medicine University of Zagreb, Croatia due to gingival ulcer which was present for eight days. Clinical examination has revealed exposed bone on the toothless alveolar ridge in the lower molar region on the right side of 0.8 cm in diameter. Otherwise, the patient was taking doxazosin due to urinary problems and ipatropium bromide due to respiratory problems. The patient wore a 6-year-old partial lower denture. He was initially treated with periodontal bandage (Resopack, HagenWerken, Germany) for the first three days and was instructed not to wear the denture; however, no benefit could be seen. Therefore, we added a local corticosteroid (betamethasone) and am oral antiseptic (chlorhexidine digluconate) applied three times a day. After 3 weeks the lesion healed. A list of possible causative factors regarding gingival ulcers is included. PMID:27688371

    To report the clinical course of 6 patients with refractory neurotrophic corneal ulcers that were treated with topical insulin drops. Retrospective chart review of patients who had neurotrophic corneal ulcers or epithelial defects refractory to standard medical and surgical treatment. Insulin drops, prepared by mixing regular insulin in artificial tears with a polyethylene glycol and propylene glycol base at a concentration of 1 unit per milliliter, were prescribed 2 to 3 times daily. Six patients, aged 2 to 73 years, developed neurotrophic corneal ulcers refractory to a range of medical and surgical treatments, including bandage contact lens, amniotic membrane grafting, and permanent tarsorrhaphy. Each patient was administered topical insulin drops with complete corneal reepithelialization within 7 to 25 days. Topical insulin may be a simple and effective treatment for refractory neurotrophic corneal ulcers. Further study is required to determine the clinical efficacy and side effect profile of insulin drops.

    Full Text Available Undisplaced talus neck fractures are uncommon and difficult to diagnose. We present a case of an 18-year-old female came with the complaints of pain and swelling in the foot following a fall from a bicycle 1½ months back. For the above complaints, she had consulted local doctors who had done X-rays of the foot and no diagnosis was made. She was treated conservatively with medications and compression bandage for swelling and the patient was allowed to walk. On presenting to us, X-ray of the foot was done and minimally displaced talus neck fracture was suspected. Magnetic resonance imaging of the foot was done and the diagnosis was confirmed. Patient was operated with percutaneous screw fixation following which below knee cast was given for 6 weeks followed by partial weight bearing. Patient returned to complete weight bearing and previous activity level without pain at the end of 3 months.

    Full Text Available The aims of this study were to produce films from phosphorylated starch/chitosan/PVA blends and evaluate their physicochemical properties. The film properties were dependent on the starch percentage in the blend. The infrared spectra of the blends showed the appearance of bands at 1716 and 1733 cm-1 (stretching C = O of PVA acetate residues and 1556 cm-1 (amide II deformation of the chitosan indicating the incorporation of these components into the blends. The films with high phosphorylated starch content showed low thermal and mechanical strength and high water absorption capacity while blends with higher content of chitosan and PVA showed good mechanical properties and low water vapor permeability. Films containing 40% and 20% starch showed excellent properties such as high water absorption capacity and biodegradability for use as bandages and agricultural films and also as a source of organic matter in soil.

    Full Text Available Uterine atony during cesarean delivery is a serious cause of maternal morbidity and mortality. Management strategies include medical treatment with uterotonic agents, manual compression of the uterus, and interventional or surgical procedures. A novel technique to compress the uterus by wrapping it with an elastic bandage and its outcome in 3 cases of uterine atony during cesarean section are presented. Our novel method of intermittent wrapping of the uterus during cesarean delivery seems to be a successful additional approach in the management of uterine atony during cesarean delivery and may be an alternative treatment option to other compressing procedures in order to avoid high blood loss and last but not least postpartum hysterectomy.

    Congenital lymphedema is the accumulation of lymphatic fluid in the child's interstitial spaces. Milroy disease is a rare, hereditary, autosomal dominant condition showing incomplete penetrance. We report the case of a 7-year old little girl with Milroy disease examined for erysipelas on congenital big right leg. A family history of large congenital member existed. Physical examination showed big oedematous right leg painful to palpation, with skin lichenification and erysipelas. Paraclinical assessment objectified cutaneous lymphedema with vascular involvement suggestive of ectasia of the right saphenous vein. Female karyotype showed no abnormalities, despite the small chromosomal rearrangements. Treatment was based on physiotherapy, bandages, compression stockings and psychotherapy. This first case in Burkina Faso testifies to the rarity of the pathology but especially to the diagnostic difficulties related to the inadequacy of paraclinical investigations.

    To retrospectively evaluate the complications, graft clarity, and outcomes associated with the use of commercially available porcine urinary bladder submucosa (ACell Vet(™) ) alone for corneal reconstruction in dogs and cats. Dogs or cats receiving an ACell Vet(™) graft for corneal reconstruction due to severe ulcerative keratitis or after a keratectomy to remove a corneal sequestrum were included. All received a single layer of ACell Vet(™) , bandage contact lens, and temporary tarsorrhaphy. Bandage contact lens and temporary tarsorrhaphy were removed after graft vascularization or epithelialization. Topical steroids, cyclosporine, tacrolimus were started after epithelialization. Based on their last examination, outcomes were categorized into five groups based on the presence of corneal vessels, appearance of the scar, and the ability to visualize the posterior and/or the anterior segment through the grafted area. There were 82 eyes included in the study, with 68 eyes with sufficient follow-up time for final assessment. Scarring was minimal in 47 eyes, moderate but not enough to obscure visualization of the posterior segment in 12, and severe in nine. There were five eyes that developed phthisis bulbi, glaucoma or were enucleated and nine that were lost to follow up. Graft dehiscence occurred in 19 eyes. Twelve healed without additional surgical intervention while three required a second graft, two became phthisical, and two were enucleated. Corneal reconstruction with ACell Vet(™) alone is a viable alternative and results in minimal scarring and complications in cats. In dogs, scarring is more pronounced than in cats and graft dehiscence rate is higher compared to conventional techniques. © 2015 American College of Veterinary Ophthalmologists.

    Despite the use of non-surgical methods to treat for the majority of midshaft fractures of the clavicle, it is remains controversial whether shortening of this bone following non-surgical treatment of a middle third fracture affects upper limb function. We conducted a cohort study by sequentially recruiting 59 patients with a fracture of the middle third of the clavicle. All patients were treated nonsurgically with a figure-of-eight bandage until clinical and radiological findings indicated healing of the fracture. Functional outcome was assessed using the Disability of Arm, Hand and Shoulder (DASH) score revalidated for the Portuguese language, other outcomes assessed included: pain measured by visual analogue scale (VAS); radiographies to measure the degree of shortening, fracture consolidation and fracture malunion. Information were also collected regarding the mechanism of injury, patient's daily activities level and epidemiological features of the patient cohort. The results of our findings are expressed as the comparison of the functional outcome with the degree of shortening. Patients were assessed six weeks and one year after injury. In the first evaluation, the mean DASH score was 28.84 and pain measured by VAS was 2.57. In the second evaluation (one year after injury) the mean DASH score was 8.18 and pain was 0.84. The mean clavicle shortening was 0.92 cm, ranging from 0 to 3 cm (SD = 0.64). There were no correlation between the degree of shortening and DASH score after six weeks and one year (p = 0.073 and 0.706, respectively). When only patients with of shortening greater than 2 cm were assessed for correlation, the result did not change. We conclude that clavicle shortening after nonsurgical treatment with a figure-of-eight bandage does not affect limb function, even when shortening exceeds 2 cm. ISRCTN85206617 .

    2013-05-01

    Phantom limb pain (PLP) is a painful sensation perceived in the missing limb after amputation. The underlying pathophysiology remains unclear. Until recently, only opioid analgesics have been proven to be effective in prospective studies. Anecdotally, patients with PLP employ self-help measures, sometimes including 'wrapping up' or rubbing their stump with aluminium foil for relief. Our hypothesis is that wrapping an amputation stump with aluminium foil perioperatively will prevent PLP in the postoperative period. From September 2007 to September 2009, 32 consecutive patients were included in a crossover, double-blinded, randomised clinical trial. Perioperative fitting of an aluminium stump bandage was compared with a placebo paper foil. Scores were noted daily in a variable diary. The observation period was 2 weeks: in the first week participants were double blinded, and in the second week there was a change of bandage from aluminium to placebo or vice versa. A visual analogue scale (VAS) score was used as primary research variable. Secondary variables were use of analgesics, VAS measures of wound pain and the incidence of wound infections. Statistical analysis was done by means of Student's t-test for non-paired observations. Baseline characteristics were similar between groups. A period effect (p= 0.84) and treatment-period interaction (p = 0.79) were not present. There was no significant difference (mean difference 0.42) between both treatments in PLP VAS scores (95% CI -2.56 to -1.81, p = 0.71). VAS measure of wound pain showed no significant difference between both groups (mean difference 0.34, 95% CI -2.32 to -1.66, p = 0.72). Also, the other secondary endpoints did not differ. Patients receiving an aluminium foil stump wrapping do not experience less phantom pain than with a placebo.

    Full Text Available Abstract Background Acute lateral ankle ligament injuries are very common problems in present health care. Still there is no hard evidence about which treatment strategy is superior. Current evidence supports the view that a functional treatment strategy is preferable, but insufficient data are present to prove the benefit of external support devices in these types of treatment. The hypothesis of our study is that external ankle support devices will not result in better outcome in the treatment of acute ankle sprains, compared to a purely functional treatment strategy. Overall objective is to compare the results of three different strategies of functional treatment for acute ankle sprain, especially to determine the advantages of external support devices in addition to functional treatment strategy, based on balance and coordination exercises. Methods/design This study is designed as a randomised controlled multi-centre trial with one-year follow-up. Adult and healthy patients (N = 180 with acute, single sided and first inversion trauma of the lateral ankle ligaments will be included. They will all follow the same schedule of balancing exercises and will be divided into 3 treatment groups, 1. pressure bandage and tape, 2. pressure bandage and brace and 3. no external support. Primary outcome measure is the Karlsson scoring scale; secondary outcomes are FAOS (subscales, number of recurrent ankle injuries, Visual Analogue Scales of pain and satisfaction and adverse events. They will be measured after one week, 6 weeks, 6 months and 1 year. Discussion The ANKLE TRIAL is a randomized controlled trial in which a purely functional treated control group, without any external support is investigated. Results of this study could lead to other opinions about usefulness of external support devices in the treatment of acute ankle sprain. Trial registration Netherlands Trial Register (NTR: NTR2151

    To profile the prescription for and adherence to breast cancer-related lymphedema (BCRL) self-care modalities among breast cancer (BrCa) survivors with BCRL in a 12-month randomized weightlifting trial. We developed a questionnaire that assessed prescription for and adherence to 10 BCRL self-care modalities that included physical therapy exercise, pneumatic compression pump, medication, lymphedema bandaging, arm elevation, self-administered lymphatic drainage, therapist-administered lymphatic drainage, compression garments, skin care, and taping. We measured prescription for and adherence to BCRL self-care modalities at baseline, 3, 6, and 12 months. Longitudinal logistic regression was used to estimate the odds ratio (OR) and 95 % confidence interval (95 % CI) associated with prescription for and adherence to BCRL modalities over time. This study included 141 BrCa survivors with BCRL. Women were prescribed an average of 3.6 ± 2.1 BCRL self-care modalities during the study. The prescription for therapist-administered lymphatic drainage (OR = 0.92, 95 % CI 0.88-0.96), pneumatic compression pump use (OR = 0.94, 95 % CI 0.89-0.98), and bandaging (OR = 0.96, 95 % CI 0.93-0.99) decreased over 12 months of follow-up. No other prescribed BCRL self-care modalities changed during the study. Over 12 months, the average adherence to all BCRL self-care modalities varied with 13, 24, 32, and 31 % of women reporting variable. The average adherence to BCRL self-care was non-optimal. Future research is necessary to prepare BrCa survivors with the knowledge, skills, abilities, and resources necessary to care for this lifelong condition.

  1. Evaluation of the effectiveness of kinesio taping application in a patient with secondary lymphedema in breast cancer: a case report

    Full Text Available Breast cancer-related lymphedema is one of the complications resulting from treatment. It is defined as arm oedema in the breast cancer patients caused by interruption of the flow of the axillary lymphatic system from surgery or radiation therapy, which results in the accumulation of fluid in the subcutaneous tissue of the arm, with a decrease in tissue distensibility around the joints and an increased weight of the extremity. Decongestive lymphatic therapy is common management for lymphedema. A program combining skin care, manual lymphatic drainage, exercise, and compression therapy (multilayer bandage or garment is recognised as the best practice in lymphedema management. Kinesio taping (KT for lymphatic drainage is a new choice in the field of physical therapy. The material and the original concept of the taping technique were introduced by Dr Kenso Kase in 1973. K-tape had been designed to allow 30-40% longitudinal stretch. It is composed of 100% cotton fibers and acrylic heat sensitive glue. Development of the technique for its administration is still ongoing. The paper discusses the case of a woman with breast cancer, in whom lymphedema occurred. The patient had three weeks of therapy. The treatment consisted of 12 manual lymphatic drainage, 12 pneumatic compressions and 3 applications of the KT method (due to the lack of standard multi-layer bandaging. During the measurement of oedema it was noted that KT had a significant effect on the reduction of lymphedema and accelerates healing effects compared to standard methods.

  2. Chronic venous leg ulcers – role of topical zinc

    Full Text Available Sara F Maher Physical Therapy Program, Department of Healthcare Sciences, Wayne State University, Detroit, MI, USA Abstract: Topical zinc has been used in the treatment of wounds for over 3,000 years, and is reported to have antiseptic, astringent, anti-inflammatory, antimicrobial, and wound healing properties. Fourteen studies were identified and reviewed, to assess the efficacy of this treatment modality as either a bandage or skin protectant in the treatment of venous ulcers. The authors of three studies reported improved healing time or success rate in wounds treated with zinc-based products. However, the authors of one study attributed the faster healing rate mainly to the extra compression (that improved venous blood return, delivered by the non-elastic paste bandage, and not by the zinc oxide alone. The quality of evidence is fair, as 50% of the studies were conducted prior to 2000 and 50% of the studies utilized fewer than 45 patients randomized to two or more groups. Other treatments have been reported to be more cost-effective than zinc, including hydrocolloids, four-layer compression systems, and CircAid Thera-boots. Finally, zinc was reported to be less comfortable, less easy to use, and caused increased pain, in comparison to other products on the market. This literature review, therefore, demonstrated that current evidence is insufficient to determine the effectiveness of zinc-based products in the treatment of venous wounds. Future research is needed focusing on larger, high-quality trials with an emphasis on quality of life issues and cost-effectiveness of treatment.

    Globally, nurses becoming more aware of getting better prepared for disaster relief, but in China, disaster nursing knowledge, courses and research are still limited. China has long been prone to disasters, but disaster nursing education and training is in its infancy. This study explored the skills, knowledge and attitudes required by registered nurses from across China who worked in the aftermath of three large earthquakes to try to determine future disaster nursing education requirements. The Questionnaire of Nurses' Disaster Nursing Skills at Earthquake Sites, assessing nursing skills, knowledge and attitudes, was distributed to 139 registered nurses in 38 hospitals in 13 provinces across China who had worked in one or more earthquake disaster zones. Descriptive statistics were used for quantitative data, and content analysis for qualitative data. Eighty-nine questionnaires were returned, a response rate of 68.3%. No respondent had ever received specific disaster nursing training prior to their post-earthquake nursing. Skills most often used by respondents were haemostasis bandaging, fixation, manual handling, observation and monitoring, debridement and dressing, and mass casualty transportation. Respondents identified that the most important groups of skills required were cardiopulmonary resuscitation; haemostasis, bandaging, fixation, and manual handling; and emergency management. They emphasized the need for psychological care of victims as well as that of fellow health workers. No respondent had ever received disaster nursing training prior to engagement at the earthquake disaster sites. All believed that there were important gaps in their knowledge and skills, and supported disaster nursing courses in the future. China urgently needs to develop disaster nursing courses, with the support of nurse leaders, educationalists and government, to implement training using an all hazards approach in accordance with international best practice and trainees

    Full Text Available Abstract Background P. mirabilis is a common uropathogenic bacterium that can cause major complications in patients with long-standing indwelling catheters or patients with urinary tract anomalies. In addition, P. mirabilis is a common cause of chronic osteomyelitis in Diabetic foot ulcer (DFU patients. We isolated P. mirabilis SCDR1 from a Diabetic ulcer patient. We examined P. mirabilis SCDR1 levels of resistance against Nanosilver colloids, the commercial Nanosilver and silver containing bandages and commonly used antibiotics. We utilized next generation sequencing techniques (NGS, bioinformatics, phylogenetic analysis and pathogenomics in the characterization of the infectious pathogen. Results P. mirabilis SCDR1 was the first Nanosilver resistant isolate collected from a diabetic patient polyclonal infection. P. mirabilis SCDR1 showed high levels of resistance against Nanosilver colloids, Nanosilver chitosan composite and the commercially available Nanosilver and silver bandages. The P. mirabilis -SCDR1 genome size is 3,815,621 bp. with G + C content of 38.44%. P. mirabilis-SCDR1 genome contains a total of 3533 genes, 3414 coding DNA sequence genes, 11, 10, 18 rRNAs (5S, 16S, and 23S, and 76 tRNAs. Our isolate contains all the required pathogenicity and virulence factors to establish a successful infection. P. mirabilis SCDR1 isolate is a potential virulent pathogen that despite its original isolation site, the wound, can establish kidney infection and its associated complications. P. mirabilis SCDR1 contains several mechanisms for antibiotics and metals resistance, including, biofilm formation, swarming mobility, efflux systems, and enzymatic detoxification. Conclusion P. mirabilis SCDR1 is the first reported spontaneous Nanosilver resistant bacterial strain. P. mirabilis SCDR1 possesses several mechanisms that may lead to the observed Nanosilver resistance.

    Full Text Available Aim: The aim of the paper was to describe chosen aspects of quality of life in patients with venous leg ulcers treated at home in the Turiec region, and to find differences in assessing quality of life in relation to degree of adherence to external compression therapy. Design: A quantitative cross-sectional study. Methods: There were 61 patients with venous leg ulcers at 68.59 ± 9.49 years of age, with an average length of wound treatment of 6.34 ± 5.51 years. The adapted self-assessment questionnaire, the Freiburg Life Quality Assessment wound module (FLQA-w, was used to gain empirical data. Results: The findings revealed that the worst score was achieved in the category of everyday life (3.61 ± 0.93. Statistically significant differences were found between the group of respondents who apply bandages on a daily basis and those who did not use them at all. Regular bandage application is closely connected with positive assessment of wound therapy (p = 0.043, psychosocial life (p = 0.023, verbalisation of well-being in various categories (p = 0.001, assessment of state of the wound (p = 0.032, assessment of health condition (p = 0.019, and overall quality of life (p = 0.014. Length of wound treatment is related to assessments of quality of life. Conclusion: Non-healing wounds, the associated therapy and financial means required to treat them, and the pain resulting from them, are connected with physical difficulty, experience of negative emotions, and, thus, the worsening of patientsʼ quality of life. The results of the study could form the basis for further studies on similar issues.

    To compare the effect of application of manuka honey with unique manuka factor (UMF) 5 or 20 with a generic multifloral honey on equine wound healing variables. Two full-thickness skin wounds (2.5 × 2.5 cm) were created on the metatarsus of both hindlimbs of eight Standardbred horses. The wounds on each horse were assigned to 1 of 4 treatments: UMF20 (UMF20) and UMF5 (UMF5) manuka honey; generic multifloral honey (GH); and a saline control. Bandages were changed daily for 12 days, after which treatment was stopped and the bandages were removed. Wound area was measured on day 1, then weekly until day 42. Overall wound healing rate (cm 2 /day) and time to complete healing were recorded. There was no difference in wound area for any of the treatments on any measurement day except for day 21, where the mean wound area for wounds treated with UMF20 was smaller than the mean wound area for the UMF5-treated wounds (P = 0.031). There was no difference in mean (± SE) overall healing rate (cm 2 /day) among the treatment groups. There were differences in mean (± SE) days to complete healing. Wounds treated with UMF20 healed faster than wounds treated with GH (P = 0.02) and control wounds (P = 0.01). Treatment of wounds with UMF20 reduced overall wound healing time compared with wounds treated with GH and control wounds. However, using this model the difference in the overall time to complete healing was small. © 2017 Australian Veterinary Association.

    Honey, alone or in combination, has been used for wound healing since ancient times and has reemerged as a topic of interest in the last decade. Pectin has recently been investigated for its use in various biomedical applications such as drug delivery, skin protection, and scaffolding for cells. The aim of the present study was to develop and evaluate a pectin-honey hydrogel (PHH) as a wound healing membrane and to compare this dressing to liquid honey. Thirty-six adult male Sprague-Dawley rats were anesthetized and a 2 × 2 cm excisional wound was created on the dorsum. Animals were randomly assigned to four groups (PHH, LH, Pec, and C): in the PHH group, the pectin-honey hydrogel was applied under a bandage on the wound; in the LH group, liquid Manuka honey was applied; in the Pec group, pectin hydrogel was applied (Pec); and in the C group, only bandage was applied to the wound. Images of the wound were taken at defined time points, and the wound area reduction rate was calculated and compared between groups. The wound area reduction rate was faster in the PHH, LH, and Pec groups compared to the control group and was significantly faster in the PHH group. Surprisingly, the Pec group exhibited faster wound healing than the LH group, but this effect was not statistically significant. This is the first study using pectin in combination with honey to produce biomedical hydrogels for wound treatment. The results indicate that the use of PHH is effective for promoting and accelerating wound healing.

    The most frequently used animal models of early weaning (EW) in rodents, maternal deprivation and pharmacological inhibition of lactation, present confounding factors, such as high stress or drug side effects, that can mask or interact with the effects of milk deprivation per se. Given these limitations, the development of new models of EW may provide useful information regarding the impact of a shortened period of breastfeeding on the endocrine and nervous systems, both during development and at adulthood. Using a model of EW in which lactating Wistar rat dams are wrapped with a bandage to block access to milk during the last three days of lactation, we have recently shown that the adult offspring presented higher body mass, hyperphagia, hyperleptinemia, leptin as well as insulin resistance, and higher adrenal catecholamine content at adulthood. Here, we used this EW model, which involves no pharmacological treatment or maternal separation, to analyze anxiety-like, novelty-seeking and memory/learning behavioral traits in the adult male offspring. To that end, animals were tested in the elevated plus maze, in the hole board arena and in the radial arm water maze. Except for an increased number of rearing events (a measure of vertical activity), no other behavioral differences were observed between EW and control animals. The contrasting behavioral results between the three EW models may be associated with differences in HPA axis function in the offspring at weaning, since it has been observed that bandaging does not affect corticosteronemia while maternal separation and pharmacological EW increase it.

    Cochlear implantation (CI) represents the gold standard in the treatment of children born deaf and postlingually deafened adults. Initial magnetic resonance imaging (MRI) was contraindicated in CI users. Meanwhile, there are specific recommendations concerning MRI compatibility depending on the type of CI system and the device manufacturer. Some CI systems are even approved for MRI with the internal magnet left in place. The aim of this study was to analyze all magnet revision surgeries in CI patients at one CI center and the relationship to MRI scans over time. Between 2000 and 2013, a total of 2027 CIs were implanted. The number of magnet dislocation (MD) surgeries and their causes was assessed retrospectively. In total 12 cases of MD resulting from an MRI scan (0.59 %) were observed, accounting for 52.2 % of all magnetic revision surgeries. As per the labeling, it was considered safe to leave the internal magnet in place during MRI while following specific manufacturer recommendations: MRI intensity of 1.5 Tesla (T) and compression head bandage during examination. A compression head bandage in a 1.5 T MRI unit does not safely prevent MD and the related serious complications in CI recipients. We recommend a Stenvers view radiograph after MRI with the internal magnet in place for early identification of MD, at least in the case of pain during or after MRI examination. MRI in CI patients should be indicated with restraint and patients should be explicitly informed about the possible risks. Recommendations regarding MRI compatibility and the handling of CI patients issued with MRI for the most common CI systems are summarized.

    Allogeneic skin grafts onto C57BL/6 mice are rejected, and the rejected skin is replaced by surrounding skin with black hair. In contrast, syngeneic skin grafts are tolerated, and gray hair grows on the grafts. To explore the mechanism of gray hair growing on the tolerated skin grafts, we prepared full-thickness skin (2-cm square) autografts, 2 (2 cm + 2 cm) horizontal or vertical parallel incisions, and U-shaped (2 cm × 2 cm × 2 cm) flaps with or without pedicle vessels. The grafts, incisions, and flaps were fixed by suturing with string and protected by a transparent bandage. On day 14 after the operation, the bandages were removed to observe the color of the hair growing on the skin. Skin autografts from wild-type or hepatocyte growth factor-transgenic (Tg) C57BL/6 mice survived with gray hair, whereas those from steel factor (Kitl)-Tg C57BL/6 mice survived with black hair. In addition, U-shaped flaps lacking both of the 2 main feeding vessels of wild-type mice had gray hair at the tip of the flaps. Light microscopy after staining with hematoxylin and eosin or dihydroxyphenylalanine showed that the formation of melanin pigment in the follicles, but not in the interadnexal skin, was susceptible to the blood supply. Melanin pigment formation in the hair bulb melanocytes appeared to be susceptible to the blood supply, and melanocytosis was promoted in the follicles and in the epidermis of Kitl-Tg C57BL/6 mice.

    posibilitó contrastar resultados y analizar el proceso de trabajo del CME.This study identifies productivity indicators at a Sterilization Central Supply (CME through documents, observation and time counting of the process for two items selected from the sample: a bandage pack and a herniorrhaphy box. The monthly average production was 30,466.42 items, and the production capacity per hour was 10.3 items per employee. The bandage pack averaged 295 minutes from the expurgation area to storage; the manual process lasted 46 minutes and the automated 88 minutes. For the herniorrhaphy box the average was 329 minutes; the manual process lasted 60 minutes and automated 98 minutes. In the bandage kit, the manual process used up 59.23% of the productivity hours in the expurgation area, 3.28% in the preparation, 10.94% in the sterilization process, and 26.31% in storage and distribution. Figures for the manual process of herniorrhaphy box were: expurgation, 11.84%; preparation, 16.20%; storage and distribution, 7.47%; and sterilization, 1.89%. The study made possible to assess the results and to analyze the working process at the CME.

    dificultades enfrentadas en ese período de su formación académica.To learn about and understand the feelings experienced by nursing students when making bandages during curricular and extracurricular clinical practice. This is a qualitative study, with a phenomenological framework. The guiding question used was: What did you feel while making the bandage? This study revealed that nursing students feel unprepared for making bandages. Students also reported various difficulties; like touching a stranger and associating theory to practice, for instance. They experienced positive emotions, like pleasure, as well as negative feelings, such as distress, insecurity, fear, and embarrassment. We believe that the teacher-student relationship would be improved if a space is created to discuss these experiences. In fact, such as space would represent one form of support, which students need due to the difficulties they have to deal with in this period of their academic education.

    Full Text Available Congenital false joint of shin occurs in 1 case per 28 000 - 190 000 live births, but it is hard-to-treat and disabling disease. Objective: Improving treatment outcomes, reducing the number of surgical interventions for the treatment of congenital false joint of shin. Materials and Methods. The method is carried out using staged plaster casts with the gradual correction of deformities. When axis of the leg approximates to the normal one, axial load is added. First, it is done by tapping on the heel. When the child was 7-8 months old he was put on the legs and taught to walk. The plaster bandage is replaced by "Scotch cast" and "soft cast" bandage. The treatment lasted up to reaching of clinical effect – correction of shin deformation and absence of pathological mobility. Clinical effect must be confirmed by roentgenography which must demonstrate filling of false joint zone with bone tissue and restoration of intramedullary canal. During all the period of treating alternate courses of electrophoresis with calcium chloride, medical mud extracts and magnetic therapy are conducted. In the period from 1995 till 2015 in the Regional Zaporizhzhia Children Clinical Hospital 4 children (6 shins aged from 1 to 7 months with false joint of shin were treated using proposed method. Results and discussion. All 4 children (6 shins treated in clinic with proposed conservative method showed filling of false joint zone with bone tissue, restoration of intramedullary canal and significant extension of axis of the shin. The load on the leg in early terms results in compression of bone fragments (as in compression-distraction osteosynthesis, magnetic therapy, electrophoresis with calcium chloride and medical mud extracts promote active functioning of the muscles that improves regional blood supply and improves osteogenesis. Conclusions. Using the proposed method of treatment of congenital false joint of shins in newborns and infants can allow avoiding surgical

    Polo, one of the world's oldest sports, is unique in merging human skill and balance with animal agility and performance in a contact sport. These modern-day 'centaurs' offer medical, dental and veterinary scientists an unrivalled, if quirky, opportunity to collaborate. Collection of epidemiological data on injuries to UK polo riders and ponies is the first step. To measure the reported risk and risk factors for injuries to UK polo ponies, their perception and mitigation by player-owners. A retrospective cohort design and telephone interviews were used. Data on equine injuries, preseason training and risk perception were collected from a random sample of player-owners using a structured questionnaire. Injuries were defined as requiring veterinary treatment. Frequencies were represented as percentages and 95% confidence intervals (CIs). Risk factors for injuries were identified by univariable and multivariable analyses. The cumulative incidence of player-owner-reported injury was 10.6% (95% CI 8.4-12.7). Tendon injuries were most common (4.3%; 95% CI 2.9-5.7), followed by wounds and splints. The only risk factor was stabling all season (odds ratio 4.79; 95% CI 1.46-15.73). Tendon injuries were perceived as the major risk and hard ground the most important risk factor. Risk mitigation practices were bandaging before exercise (45.7%; 95% CI 34.8-56.5), checking tendons (84.0%; 95% CI 76.0-91.9), cold hosing (40.7%; 95% CI 30.0-51.4), bandaging (38.3%; 95% CI 27.7-48.9) and using clays and coolants after exercise (24.7%; 15.3-34.1). Cuts and wounds were considered most frequent by only 2.5% (95% CI 0.0-3.6) of players but were the second most common injury, accounting for 21.6% of veterinary treatments. Splints accounted for 12.5% of injuries. The risk of injury to polo ponies is similar to that in the general horse population; musculoskeletal injuries, particularly tendon injuries, are most common, followed by wounds and splints.

Some studies have shown reduced surgical time, postoperative pain, time in the postanesthesia care unit (PACU, incidence of urinary retention, postoperative nausea, and more favorable cost-effectiveness with spinal anesthesia. Despite these results, the current literature has also shown contradictory results in between-group comparisons. Materials and methods: A retrospective analysis was performed by querying the electronic medical record database for surgeries performed by a single surgeon between 2007 and 2011 using procedural codes 63030 for diskectomy and 63047 for laminectomy: 544 lumbar laminectomy and diskectomy surgeries were identified, with 183 undergoing general anesthesia and 361 undergoing spinal anesthesia (SA. Linear and multivariate regression analyses were performed to identify differences in blood loss, operative time, time from entering the operating room (OR until incision, time from bandage placement to exiting the OR, total anesthesia time, PACU time, and total hospital stay. Secondary outcomes of interest included incidence of postoperative spinal hematoma and death, incidence of paraparesis, plegia, post-dural puncture headache, and paresthesia, among the SA patients. Results: SA was associated with significantly lower operative time, blood loss, total anesthesia time, time

    An ideal hemostatic dressing that would control bleeding and protect the wound from further contamination is still being sought for combat casualty care. The new SilverLeaf™ (SL) bandage was made of material containing active hemostatic property and possible antimicrobial property from silver coating. This study was conducted to compare and ascertain the hemostatic properties of SL and compare it with known hemostatic dressings: Combat Gauze® (CG) and WoundStat™ (WS) in a swine model with punch, vascular injury. Three hemostatic dressings were evaluated in anesthetized Yorkshire swine hemorrhaged for 45 sec in a femoral arterial puncture model. The hemostatic dressings SL, CG, or WS were applied on an actively bleeding wound, followed by 5 minutes of compression at 200 mm Hg. The pressure was then released to baseline and skin closed with towel clamps. After 15 minutes, 500 ml of (Hextend) resuscitation fluid infused over a period of 30 minutes. The animal's vital signs were monitored for the 3-hour experiment period. Primary outcomes documented were incidence of bleeding after application of the dressing, restoration of MAP and rate of survival.Results. The pre-treatment blood loss for WS was 375.66 ml (16.49%), SL 282.08 ml (12.15%) and CG 307.24 ml (12.68%) and was comparable between groups (p>0.56). The post-treatment blood loss for WS was 286.05 ml (10.65%), SL 386.81 ml (16.92%), and CG 525.76 ml (21.52%). There was no significant difference in post-treatment blood loss (p>0.37) between groups. The Mean Arterial Pressure (MAP) did not significantly differ between the groups at all time points compared. The SL and CG had comparable MAPS during the first hour. The SL had a slight advantage, but didn't reach statistical significance. This suggests that all the bandages were comparable. The two time points at which the post-treatment bleeding occurred in the three groups after the release of manual compression and after restoration of blood pressure. The

    Full Text Available Background: Radial artery (RA occlusion (RAO is not rare in patients undergoing coronary intervention by transradial approach (TRCI. Predictors of and prevention from RAO have not been systematically studied. This study aimed to analyze the risk factors of the weakness of RA pulsation (RAP and its predictive value for RAO after TRCI, and simultaneously to describe a feasible and effective approach to maintain RA patency. Methods: Between June 2006 and March 2010, all patients who underwent TRCI were classified according to the weakness of RAP after removing compression bandage with confirmation by Doppler ultrasound for the first 30 consecutive patients. Among a total of 2658 patients studied, 187 (7% patients having a weaker RAP were prospectively monitored. At 1 h after bandage removal, the ulnar artery in puncture side of all patients was blocked with manual compression to favor brachial and collateral artery blood flow through the RA until a good RAP was restored. The primary analysis was the occurrence of RAO. Results: Doppler ultrasound demonstrated the significant reduction of both systolic velocity (61.24 ± 3.95 cm/s vs. 72.31 ± 3.57 cm/s and diastolic velocity (1.83 ± 0.32 cm/s vs. 17.77 ± 3.97 cm/s in RA at access side as compared to the contralateral RA (all P < 0.001, but these velocities in ipsilateral ulnar artery (81.2 ± 2.16 cm/s and 13.1 ± 2.86 cm/s, respectively increased profoundly. The average time of ulnar artery compression was 4.1 ± 1.2 h (ranged 2.5-6.5 h. There were two patients experienced persistent RAO with a success rate of 98.9% and RAO in 0.075% of patients after ulnar artery compression was applied. The pulsation of the ulnar artery after compression was removed had not been influenced by the compression. Conclusions: After intervention using TRCI approach, the presence of a weaker RAP is an indicator of imminent RAO. The continuing compression of ipsilateral ulnar artery is an effective approach to

All require a specific approach, as well as the interdisciplinary participation of different members of the team. But in general, established local cure plans may be quite similar. Applies them technology lipid colloidal (TLC) which consists of the combination of particles of hydrocolloid (carboxymethylcellulose) with lipid components. Products with a technology designed for every moment of healing. Show our experience in the use of products with TLC in patients with ulcers of different etiologies. The following products depending on the case have been used to treat: UrgoTul Absorb Border, Urgoclean (rope or plate), UrgoStart, UrgoK2 and UrgoK2 LITE. These products were applied in patients presenting four different etiologies of ulcer: hypertensive, traumatic, venous and ischemic ulcer. The use of Urgoclean rope favored cleaning the bed ulceral and applied Urgoclean plate with reinforced alginate to control the abundant exudates, with coverage of UrgoTul ABsorb Border. Once clean beds pass UrgoStart and at all times UrgoK2 bandage, cases that required compressive therapy. Intolerance to that kind of compression applied to patients presenting bandage UrgoK2 LITE (which tolerated without problem) which significantly reduced edema, favoring the control of exudate. Patients with ulcer of long evolution, at the start were reluctant to the application of new technologies, but after the first cures and sensing a good evolution, we get their confidence and commitment to the resolution. Are displayed clinical cases of different etiologic and personal contexts that an integral and interdisciplinary approach together with the application of products with TLC, managed to solve the problem. The materials used have been satisfactory in all cases, with a direct involvement in the resolution of lesions which carries a long unresolved, and in any of them, even with a

    Facial reconstruction of mummies and corpses in general is important in anthropological, medical, and forensic studies. The purpose of our study was to evaluate the role of MDCT examination for 3D facial reconstruction and report the results of multidisciplinary work performed by radiologists, anthropologists, and forensic police in reconstructing the possible physiognomy of an ancient Egyptian mummy. Three-dimensional MDCT data were obtained from a well-preserved, completely wrapped Egyptian mummy from the collection of the Egyptian Museum in Torino, Italy, which dated from the XXII or XXIII dynasty (945-715 BC). Data were used as a model for the rapid prototyping stereolithographic technique, a method that allows the creation of a 3D model with digital data using synthetic materials such as a resin or nylon. The physical creation of the face was accomplished with boosting techniques performed by the progressive layering of plasticine on the nylon model according to the anthropometric data, the conditions of the soft residual dehydrated tissues, and the most accepted scientific and anthropological criteria. CT is the only noninvasive method for obtaining fundamental data for 3D reconstructions of the skull and the body, especially with wrapped mummies. Our multidisciplinary cooperative study produced a model of the face of an individual who lived nearly 3,000 years ago, which would not previously have been possible unless we unwrapped, destroyed, and altered the conservation of the bandages and the mummy.

    Full Text Available BACKGROUND: Buruli ulcer is an infectious disease involving the skin, caused by Mycobacterium ulcerans. This disease is associated with areas where the water is slow-flowing or stagnant. However, the exact mechanism of transmission of the bacillus and the development of the disease through human activities is unknown. METHODOLOGY/PRINCIPAL FINDINGS: A case-control study to identify Buruli ulcer risk factors in Cameroon compared case-patients with community-matched controls on one hand and family-matched controls on the other hand. Risk factors identified by the community-matched study (including 163 pairs were: having a low level of education, swamp wading, wearing short, lower-body clothing while farming, living near a cocoa plantation or woods, using adhesive bandages when hurt, and using mosquito coils. Protective factors were: using bed nets, washing clothes, and using leaves as traditional treatment or rubbing alcohol when hurt. The family-matched study (including 118 pairs corroborated the significance of education level, use of bed nets, and treatment with leaves. CONCLUSIONS/SIGNIFICANCE: Covering limbs during farming activities is confirmed as a protective factor guarding against Buruli ulcer disease, but newly identified factors including wound treatment and use of bed nets may provide new insight into the unknown mode of transmission of M. ulcerans or the development of the disease.

    Full Text Available BACKGROUND: Buruli ulcer (BU is an infection of the subcutaneous tissue leading to chronic necrotizing skin ulcers. The causative pathogen, Mycobacterium ulcerans, grows best at 30 degrees C-33 degrees C and not above 37 degrees C. We explored the safety, tolerability and efficacy of phase change material (PCM, a novel heat application system for thermotherapy of BU. METHODOLOGY/PRINCIPAL FINDINGS: In a prospective observational single centre proof-of-principle trial in Ayos/Cameroon, six laboratory reconfirmed patients with ulcerative Buruli lesions received 28-31 (ulcers 2 cm days of thermotherapy with the PCM sodium acetate trihydrate as heat application system. This PCM is widely used in commercial pocket heat pads, it is easy to apply, rechargeable in hot water, non-toxic and non-hazardous to the environment. All patients enrolled in the trial completed treatment. Being completely mobile during the well-tolerated heat application, acceptability of the PCM bandages was very high. In patients with smaller ulcers, wounds healed completely without further intervention. Patients with large defects had skin grafting after successful heat treatment. Heat treatment was not associated with marked increases in local inflammation or the development of ectopic lymphoid tissue. One and a half years after completion of treatment, all patients are relapse-free. CONCLUSIONS/SIGNIFICANCE: Our reusable PCM-based heat application device appears perfectly suited to treat BU in endemic countries with limited resources and infrastructure.

    To report the use of compression resistant matrix (CRM) infused with recombinant human bone morphogenetic protein (rhBMP-2) prospectively in the healing of nonunion long-bone fractures in dogs. A longitudinal cohort of dogs that were presented with nonunion fractures were classified and treated with CRM soaked with rhBMP-2 and fracture fixation. They were followed with serial radiographs and evaluated for healing times and complications according to the time frame and definitions previously established for orthopaedic clinical cases. Eleven nonunion fractures in nine dogs were included. Median healing time was 10 weeks (range: 7-20 weeks). Major perioperative complications due to bandage morbidity were encountered in two of 11 limbs and resolved. All other complications were minor. They occurred perioperatively in eight of 11 limbs. Minor follow-up complications included short-term in one of two limbs, mid-term in one of three, and long-term in four of five limbs. Nine limbs returned to full function and two limbs returned to acceptable function at the last follow-up. Nonunion fractures given a poor prognosis via standard-of-care treatment were successfully repaired using CRM with rhBMP-2 accompanying fixation. These dogs, previously at high risk of failure, returned to full or acceptable function.

    With ever increasing emphasis on nanotechnology, silver nanoparticle are being considered for many antimicrobial needs ranging from catheter coatings, to burn wound bandages. Current synthesis methods for creating silver nanoparticles typically call for potentially hazardous chemicals, extreme heat, and produce environmentally dangerous byproducts. As a culture intent on reducing our carbon footprint on the earth, societies' focus has turned to ``green'' production capabilities. Therefore, if nanotechnology is to continue to grow at its current rate it is essential that novel ``green'' synthesis of nanoparticles becomes a reality. Furthermore, with the current and near-future applications of silver nanoparticles in biological systems it is imperative to fully analyze the potential toxic effects of these nanoparticles. In this study we have shown that by reducing silver nitrate in solutions of tea extract or epinephrine of varying concentrations spherical silver nanoparticle are formed. Furthermore, evaluation of mitochondrial function (MTS) and membrane integrity (LDH) in alveolar rat macrophages and human keratinocytes showed that these ``green'' synthesized silver nanoparticles were nontoxic.

    Jellyfish (cnidarians) have a worldwide distribution. Despite most being harmless, some species may cause local and also systemic reactions. Treatment of jellyfish envenomation is directed at: alleviating the local effects of venom, preventing further nematocyst discharges and controlling systemic reactions, including shock. In severe cases, the most important step is stabilizing and maintaining vital functions. With some differences between species, there seems to be evidence and consensus on oral/topical analgesics, hot water and ice packs as effective painkillers and on 30 s application of domestic vinegar (4%–6% acetic acid) to prevent further discharge of unfired nematocysts remaining on the skin. Conversely, alcohol, methylated spirits and fresh water should be carefully avoided, since they could massively discharge nematocysts; pressure immobilization bandaging should also be avoided, as laboratory studies show that it stimulates additional venom discharge from nematocysts. Most treatment approaches are presently founded on relatively weak evidence; therefore, further research (especially randomized clinical trials) is strongly recommended. Dissemination of appropriate treatment modalities should be deployed to better inform and educate those at risk. Adequate signage should be placed at beaches to notify tourists of the jellyfish risk. Swimmers in risky areas should wear protective equipment. PMID:23434796

    Full Text Available Background: Surgical intervention for corneal perforation is indicated when the anterior chamber does not reform within a short period of time. Herein, we report the successful management of a small paracentral corneal perforation using autologous iris incarceration and tissue adhesive. Case: A 41-year-old man developed a small paracentral corneal perforation (0.5 mm in size in the right eye, while the treating physician attempted to remove the residual rust ring after removal of a piece of metallic foreign body. Observations: The eye was initially managed with a bandage soft contact lens to ameliorate the aqueous leakage; however, without success. Iatrogenic iris incarceration of the wound was first induced, followed by application of cyanoacrylate tissue adhesive to the perforated site. As a result, the anterior chamber was immediately reformed and maintained. Complete corneal epithelialization of the perforation was achieved in 2 months without visual compromises. Conclusions: Cyanoacrylate tissue adhesive with iatrogenic incarceration of the autologous iris was effective in treating this type of small corneal perforation. This technique is simple and potentially useful for small paracentral corneal perforations outside the visual axis and without good apposition.

    Unfavourable socioeconomic and political conditions delayed stronger development of medicine in Croatia until the last decades of the 19th century and the turn of the 20th century. This relatively short period saw the establishment of a number of key healthcare institutions such as the institute for smallpox vaccine production, department of bacteriology and hygiene, tuberculosis sanatorium, paediatric outpatient clinic, emergency medical facility, and dissection facility. Hospitals became centres of medical research and started to develop specific clinical professions. New medical associations saw the light of day [Sbor liecnika kr. Hrvatske i Slavonije (Association of Physicians of the Kingdom of Croatia and Slavonia) in Zagreb and DruZtvo slavonskih liecnika (Society of Physicians of Slavonia) in Osijek] and started their own bulletins Liecnicki viestnik and Glasnik DruZtva slavonskoh liecnika, respectively. Medical training was then provided by a midwifery school and a university school of pharmacy, while the Austrian government discouraged medical studies at the local level for decades, as it feared it would create a new class of free-thinking intellectuals. Those times also saw the first welfare institutions. Croatia was not producing pharmaceuticals at the time, but there was a new factory producing medical instruments, orthopaedic devices, and bandages.

    On June 1994, the National Institute of Nuclear Research (ININ) and the South Central Hospital for High Specialty of PEMEX (HCSAE) began a joint work with the finality to obtain radio sterilized amniotic membranes for to be used as cover (biological bandage) in burnt patients. Subsequently the Chemistry Faculty of UNAM and the National Institute of Cardiology began to collaborate this last with interest on cardiac valves for graft. Starting from 1997, the International Atomic Energy Agency (IAEA) supports this project (MEX/7/008) whose main objective is to set up the basis to establish in Mexico a Radio sterilized Tissue Bank (amniotic membranes, skin, bones, tendons, cardiac valves, etc.) to be used with therapeutic purposes (grafts). The IAEA support has consisted in the equipment acquisition which is fundamental for the Tissue Bank performance such as an experimental irradiator, laminar flow bell, lyophilizer, vacuum sealer and special knives for tissues. Also visits to Mexico of experts have been authorized with the aim of advising to the personnel which participate in the project and scientific visits of this personnel to another tissue banks (Sri Lanka and Argentine). The establishment in Mexico of a Tissue bank will be a great benefit because it will have availability of distinct tissues for grafts and it will reduce the synthetic materials importation which is very expensive.

It suggests that these kinds of traumas suffered during adulthood may involve a disintegration of the self and a loss of 'psychic skin'. This conceptualization is derived from the treatment of a refugee who survived multiple extreme traumas and with whom efforts were made in therapy to identify a complex methodology making use of supplementary therapeutic tools in addition to individual psychotherapy. The case demonstrates how the disintegration of self implies not only a deep somato-psychic dissociation, but also a loss of intrapsychic and interpersonal space. In the treatment this was worked through via repetition of the victim-aggressor dynamics at multiple levels. In the end, the therapeutic context was structured like a set of concentric layers, creating a 'bandage' over the patient's wounds whilst his 'psychic skin' was able to regenerate. The conditions triggered by extreme traumas in refugees challenge some of the cornerstones of individual psychoanalytic technique, as well as the idea that individual therapy may be thought of as existing in an environmental vacuum. © 2017, The Society of Analytical Psychology.

    Intravenous regional anesthesia (IVRA) is a useful ED anesthetic technique. However, venous pressure elevation during injection can cause anesthetic leakage and toxicity. This is minimized by preinjection limb exsanguination. Although standard, Esmarch exsanguination is intolerable with limb trauma. Thus, the authors' objective was to study alternative methods. Volunteers had upper limb exsanguination performed by Esmarch bandage, arm elevation/arterial compression (AE/AC), and a pneumatic vinyl splint. Resultant volume changes, measured by volume displacement, were normalized, and expressed as percent decreases from baseline. Volume changes of all three methods were compared. The physiologic effectiveness of the AE/AC method was tested by measuring IV pressures during simulated IVRA. Attainment of maximum venous pressure (MVP) indicated leakage under the tourniquet. All methods reduced limb volume compared with baseline (p 0.99), but neither method was as effective as Esmarch (p < 0.05). Gender differences were noted in absolute volumes exsanguinated, but there was no difference in percent exsanguination. The AE/AC method was the simplest procedure to perform. Peak IV pressure during simulated IVRA after AE/AC was 85 mm Hg (males), and 199 mm Hg (females) (p < 0.05). The MVP was not reached. While Esmarch was the most effective exsanguinating method, the two alternatives provided significant and equivalent decreases in limb volume. The AE/AC technique was physiologically effective in preventing attainment of MVP. Further studies are indicated to determine the clinical effectiveness of this technique in providing anesthesia for patients with limb trauma.

    There is no universal approach to surgery aftercare among foot and ankle surgeons. Although infections following foot and ankle surgery are rare, soft tissue healing can be jeopardized after extensive and multiple approaches. We defined a precise fixation technique of the foot and ankle in the immediate post-operative phase using what we call "the Jones dressing cast". This technique is a modification of the Jones dressing bandage. In a previous study we compared two groups of patients (N=20/23) who underwent similar reconstructive surgery with the application of the described cast for one week and without. At the two-month follow-up we observed that the group treated with the cast required less pain relief, spent less time in hospital and achieved faster autonomy using crutches (Gottlieb and Klaue, 2013). In this study we considered a group of 45 patients who underwent similar reconstructive procedures to those in the first study and who were treated with the cast for two weeks post-operatively. There was no visual check of the soft tissues before removal of the cast. Unlike the earlier study, the results from this second study were more significant. Revision surgery occurred far less frequently in the group wearing the cast for two weeks. The reduced strain to the soft tissue around the foot due to the cast and less manipulation of the wound dressing decrease complications in the post-operative period.

    Carboxymethyl cellulose (CMC) is a plant-derived material that has high biocompatibility and water solubility. We developed a CMC nonwoven sheet as a hemostatic agent by carboxymethylating a continuous filament cellulose nonwoven sheet. The CMC nonwoven sheet was able to absorb water and dissolve in it. The rates of absorption and dissolution depended on the degree of carboxymethylation. After dissolving in blood, CMC accelerated clot development (possibly owing to the incorporation of CMC into fibrin fibers) and increased the viscosity of the blood, both of which would contribute to the improved blood clotting of an injured surface. In vivo experiments using a rat tail cutting method showed that a CMC nonwoven sheet shortened the bleeding time of the tail when applied to the cut surface. The hemostatic effect of the CMC nonwoven sheet was almost at the same level as a commercial hemostatic bandage. These results suggest that a CMC nonwoven sheet could be used as a novel sheet-type hemostatic agent. Copyright © 2014 The Society for Biotechnology, Japan. Published by Elsevier B.V.

    Background: `Tisseel' (Baxter Healthcare, Deerfield, IL) is a fibrin-based sealant that is commonly used during spine surgery to augment dural repairs. We wish to intra-operatively secure a near infrared spectroscopy (NIRS) sensor to the dura in order to monitor the tissue hemodynamics of the underlying spinal cord. To determine if `Tisseel' sealant adversely attenuates NIR photon transmission. Methods: We investigated `Tisseel' in both an in vitro and in vivo paradigm. For in vitro testing, we used a 1 mm pathlength cuvette containing either air or `Tisseel' interposed between a NIR light source (760 and 850 nm) and a photodiode detector and compared transmittance. For in vivo testing, a continuous wave (760 and 850 nm) spatiallyresolved NIRS device was placed over the triceps muscle using either conventional skin apposition (overlying adhesive bandage) or bioadhesion with `Tisseel'. Raw optical data and tissue saturation index (TSI%) collected at rest were compared. Results: In-vitro NIR light absorption by `Tisseel' was very high, with transmittance reduced by 95% compared to air. In-vivo muscle TSI% values were 80% with conventional attachment and 20% using fibrin glue. Conclusion: The optical properties of `Tisseel' significantly attenuate NIR light during in-vitro transmittance and critically compromise photon transmission in-vivo.

    Full Text Available An 18-year-old woman was referred with late sequelae of chloroquine-induced Steven-Johnson syndrome. At the time of presentation, the symblepharon was involving the upper lids to almost the whole of the cornea, and part of the lower bulbar conjunctiva with the lower lid bilaterally. Other ocular examinations were not possible due to the symblepharon. B-scan ultrasonography revealed acoustically clear vitreous, normal chorioretinal thickness, and normal optic nerve head, with an attached retina. Conjunctivo-corneal adhesion released by superficial lamellar dissection of the cornea. Ocular surface reconstruction was carried out with a buccal mucous membrane. A bandage contact lens was placed over the cornea followed by the symblepharon ring to prevent further adhesion. The mucosal graft was well taken up along with corneal re-epithelization. Best corrected visual acuity of 20/120 in both sides after 1 month and 20/80 after 3 months was achieved and maintained till the 2.5-year follow-up.

    Full Text Available In this survey, 55 patients were studied in a period of six years for having the anesthesia in the sitting position. In this position, the surgeon will had a better access to the location, whose damages have been sustained, so less damages would be given to the healthy tissues. For the patients, due to their critical general conditions, one week prior to giving anesthesia to the posterior fossa, operation in the sitting position the right ventriculoatiral shunt was placed. For preventing the fall of blood pressure, a bandage was placed in the lower limbs after inducing anesthesia and changing supine position to sitting position. Before the induction, central venous pressure was measured for treating the air embolism. The head of catheter was placed inside the right atrial. Premedications such as atropine, pethidine, and inductive agents like thiopenton, and muscle relaxants, maintained with halothane and nitrous oxide. All of the patients endured this condition without the fall of blood pressure and air embolism

    Effective method of obtaining of the bactericidal bandage materials by impregnation of cotton fabric by aqueous solutions of silver and copper salts followed by a certain regime of heat treatment is developed. The study of obtained materials by methods of optical spectroscopy, electron microscopy, and X-ray phase analysis showed the formation of crystalline silver nanoparticles (NPs) and bimetallic Ag/Cu composites with the corresponding surface plasmon resonance (SPR) bands in the absorption spectra. High antimicrobial and antimycotic properties of tissues with low concentrations of Ag and Ag/Cu nanoparticles (Ag/Cu NPs) (in the range 0.06-0.25 weight percent (wt%) for Ag and 0.015-0.13 wt% for Ag/Cu) is confirmed in experiments with a wide range of multidrug-resistant bacteria and fungi: Escherichia coli, Enterobacter aerogenes, Proteus mirabilis, Klebsiella pneumoniae, Candida albicans yeasts, and micromycetes . Textile materials with Ag NPs demonstrate high antibacterial activity, while fabrics doped with bimetallic composite Ag/Cu have pronounced antimycotic properties. Bactericidal and antifungal properties of the obtained materials do not change after a washing. Production of such materials is extremely fast, convenient, and cost-effective.

    In this work, hydrogel membranes were developed based on poly vinyl alcohol (PVA), starch (St), and chitosan (Cs) hydrogels with nano Zinc oxide (nZnO). PVA/St/Cs/nZnO hydrogel membranes were prepared by freezing-thawing cycles, and the aqueous PVA/St solutions were prepared by dissolving PVA in distilled water. After the dissolution of PVA, starch was mixed, and the mixture was stirred. Then, chitosan powder was added into acetic acid, and the mixture was stirred to form a chitosan solution. Subsequently, Cs, St and PVA solutions were blended together to form a homogeneous PVA/St/Cs ternary blend solution. Measurement of Equilibrium Swelling Ratio (ESR), Water Vapor Transmission Test (WVTR), mechanical properties, scanning electron microscopy (SEM), MTT [3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide] assay, antibacterial studies, in vivo wound healing effect and histopathology of the hydrogel membranes were then performed. The examination revealed that the hydrogel membranes were more effective as a wound dressing in the early stages of wound healing and that the gel could be used in topic applications requiring a large spectrum of antibacterial activity; namely, as a bandage for wound dressing.

    Lunara Basqueroto Della Justina

    Full Text Available Abstract Introduction: Head and neck lymphedema is considered a chronic and complex complication with potential to cause physical, functional, emotional and social impairment. Objective: To identify the approaches to physical therapy used to treat head and neck cancer-related lymphedema. Method: A bibliographic search was conducted in February and March 2012 in books and electronic databases, LILACS, MEDLINE, SCIELO, Cochrane, PEDro, and BDTD using the following keywords: lymphedema, treatment, head and neck cancer, and physical therapy connected by the Boolean operator AND without a specific time frame. Results and discussion: Early diagnosis and assessment is key to properly managing and effectively treating lymphedema. Diagnosis is reached through clinical history and physical assessment by measuring the distance between two anatomical landmarks, circumference measures, and lymphedema rating scales. Complex decongestive therapy, which includes manual lymph drainage, compressive bandaging, kinesiotherapy and skin care, is the technique most frequently used and currently considered to be the gold standard. Conclusions: No consensus is reported in the literature in regard to a standard procedure to assess and treat head and neck cancer-related lymphedema. Assessments and treatments described in the literature are mainly restricted to the limbs; therefore, further studies are needed to support effective clinical actions in the physical therapy approach to this condition.

    Full Text Available Abstract Background Functional treatment is a widely used and generally accepted treatment for ankle sprain. A meta-analysis comparing the different functional treatment options could not make definitive conclusions regarding the effectiveness, and until now, little was known about patient satisfaction in relation to the outcome. Methods Patients with acute ankle sprain received rest, ice, compression and elevation with an compressive bandage at the emergency department. After 5-7 days, 100 patients with grade II and III sprains were randomized into two groups: one group was treated with tape and the other with a semi-rigid ankle brace, both for 4 weeks. Post-injury physical and proprioceptive training was standardized. As primary outcome parameter patient satisfaction and skin complications were evaluated using a predefined questionnaire and numeric rating scale. As secondary outcome parameter the ankle joint function was assessed using the Karlsson scoring scale and range of motion. Results Patient-reported comfort and satisfaction during treatment with a semi-rigid brace was significantly increased. The rate of skin complication in this group was significantly lower compared to the tape group (14.6% versus 59.1%, P  Conclusion Treatment of acute ankle sprain with semi-rigid brace leads to significantly higher patient comfort and satisfaction, both with similar good outcome.

    On June 1994, the National Institute of Nuclear Research (ININ) and the South Central Hospital for High Specialty of PEMEX (HCSAE) began a joint work with the finality to obtain radio sterilized amniotic membranes for to be used as cover (biological bandage) in burnt patients. Subsequently the Chemistry Faculty of UNAM and the National Institute of Cardiology began to collaborate this last with interest on cardiac valves for graft. Starting from 1997, the International Atomic Energy Agency (IAEA) supports this project (MEX/7/008) whose main objective is to set up the basis to establish in Mexico a Radio sterilized Tissue Bank (amniotic membranes, skin, bones, tendons, cardiac valves, etc.) to be used with therapeutic purposes (grafts). The IAEA support has consisted in the equipment acquisition which is fundamental for the Tissue Bank performance such as an experimental irradiator, laminar flow bell, lyophilizer, vacuum sealer and special knives for tissues. Also visits to Mexico of experts have been authorized with the aim of advising to the personnel which participate in the project and scientific visits of this personnel to another tissue banks (Sri Lanka and Argentine). The establishment in Mexico of a Tissue bank will be a great benefit because it will have availability of distinct tissues for grafts and it will reduce the synthetic materials importation which is very expensive.

    Full Text Available This report characterizes the digital dermatitis (DD lesions in the accessory digits of dairy cows and presents data on the applied therapy. Fifteen Holstein cattle with DD affecting the accessory digits of the hindlimbs from four dairy farms with previous history of DD were evaluated. Lesions were excised, the wounds were sutured, and a topical application of oxytetracycline powder covered by bandaging was associated with a single parenteral administration of long acting oxytetracycline IM (20mg/kg. Tissue samples were obtained for histopathology and transmission electronic microscopy (TEM. Lesions from all the animals were recuperated 15 days after surgical procedure. Overal, most DD lesions were papillomatous epidermal projections or wartlike verrucous lesions. Histopathologically, samples revealed hyperplasia of epidermis with hyperkeratosis, several mitoses in the stratum basale and elongated rete ridges in the superficial and middle dermis. TEM revealed long, thin spirochete-like bacteria. Morphologic features of lesions and its response to therapy were comparable to those described for DD.

    Tattoo-like epidermal sensors are an emerging class of truly wearable electronics, owing to their thinness and softness. While most of them are based on thin metal films, a silicon membrane, or nanoparticle-based printable inks, we report sub-micrometer thick, multimodal electronic tattoo sensors that are made of graphene. The graphene electronic tattoo (GET) is designed as filamentary serpentines and fabricated by a cost- and time-effective "wet transfer, dry patterning" method. It has a total thickness of 463 ± 30 nm, an optical transparency of ∼85%, and a stretchability of more than 40%. The GET can be directly laminated on human skin just like a temporary tattoo and can fully conform to the microscopic morphology of the surface of skin via just van der Waals forces. The open-mesh structure of the GET makes it breathable and its stiffness negligible. A bare GET is able to stay attached to skin for several hours without fracture or delamination. With liquid bandage coverage, a GET may stay functional on the skin for up to several days. As a dry electrode, GET-skin interface impedance is on par with medically used silver/silver-chloride (Ag/AgCl) gel electrodes, while offering superior comfort, mobility, and reliability. GET has been successfully applied to measure electrocardiogram (ECG), electromyogram (EMG), electroencephalogram (EEG), skin temperature, and skin hydration.

    To evaluate the efficacy of a nerve block as an alternative technique for analgesia after knee arthroplasty and to indicate the usefulness and advantages of the anterior approach to the sciatic nerve block. Between April 2004 and March 2006, we studied a series of consecutive patients undergoing knee arthroplasty in which a subarachnoid block was used as the anesthetic technique and postoperative analgesia was provided by means of a combined peripheral femoral nerve block and an anterior sciatic nerve block. We evaluated the mean length of time free from pain, quality of analgesia, and length of stay in hospital. Seventy-eight patients were included in the study. The mean (SD) length of time free from pain for the group was 42.1 (3.9) hours. Patients reported mild pain after 34.8 (4.1) hours and moderate to severe pain after 42.4 (3.5) hours. By the third day, 62.8% of patients were able to bend the knee to 90 degrees. There were no complications resulting from the technique and the level of patient satisfaction was high. A combined femoral-sciatic nerve block is effective in knee arthroplasty. It controls postoperative pain and allows for early rehabilitation. The anterior approach to the sciatic nerve is relatively simple to perform without removing the pressure bandaging from the thigh after surgery. This approach also makes it unnecessary to move the patient.

    The amniotic membrane (AM) is the innermost layer of the fetal membranes (placenta), widely used in transplantation being a tissue that combines anti-inflammatory, antimicrobial and antifibrotic, and limited immunogenicity. The tissue can be used a bandage biological for treatment of burns and skin wounds, chronic ulcers, reconstructions from different body areas, including ophthalmic repairs. In the last decades the amniotic membrane has been used widely also as a carrier substrate to transfer tissues cultured 'in vitro'. The use of fresh membrane has some limitations, the main ones are being necessary your quick use and the inability to obtain full security for certain infections. Other types of preservation require a processing thereof. The radiosterilization is an alternative for ensuring quality and safety of tissues used in transplants, and other clinical applications in order to minimize the risk of contamination of the receptor tissue. Therefore, the objective of this study was to test various doses of radiation using two sources of ionizing radiation: the cobalt-60 irradiator Gamma and Electron Beam Accelerator (E.B.). A tissue analysis was done by visual and tactile qualitative analysis, semi-quantitative (solid colorimetry) and light microscopy to observe morphological and physic-chemical changes after the irradiation of AM preserved in glycerol, comparing the results obtained with the sample not irradiated. It was noted that at higher doses, for both radiation sources, irradiated membranes suffered greater color change, becoming yellowish and thereby reducing their initial malleability. (author)

    Applying HTS conductors in the rotor of synchronous machines allows the design of future motors or generators that are lighter, more compact and feature an improved coefficient of performance. To address these goals a project collaboration was installed within Siemens, including Automation & Drives, Large Drives as a leading supplier of electrical machines, Corporate Technology as a competence center for superconducting technology, and other partners. The main task of the project was to demonstrate the feasibility of basic concepts. The rotor was built from racetrack coils of Bi-2223 HTS tape conductor, these were assembled on a core and fixed by a bandage of glass-fibre composite. Rotor coil cooling is performed by thermal conduction, one end of the motor shaft is hollow to give access for the cooling system. Two cooling systems were designed and operated successfully: firstly an open circuit using cold gaseous helium from a storage vessel, but also a closed circuit system based on a cryogenerator. To take advantage of the increased rotor induction levels the stator winding was designed as an air gap winding. This was manufactured and fitted in a standard motor housing. After assembling of the whole system in a test facility with a DC machine load experiments have been started to prove the validity of our design, including operation with both cooling systems and driving the stator from the grid as well as by a power inverter.

    To review the effects achieved by the kinesio tape in patients with stroke in scientific studies published on date and to discuss these findings may be of interest to neurology. An exhaustive search in the main scientific databases using keywords such as kinesio tape, kinesiotaping, musculoskeletal tape, taping medical concept was carried out. Citations of selected articles and scientific papers published on the website of the Spanish Association of Neuromuscular Bandage were analyzed. Experimental, quasi-experimental, clinical trials and case studies published were used, without limit date, with therapeutical treatment purpose provide important results. Eight articles have met the inclusion criteria. There are eight studies that examine the effect on kinesio tape on lower limb, gait and balance in this kind of therapy, even upper limb and swallowing problems that these patients could present. The kinesio tape in neurological patients can be a complementary technique that empirically provides benefits. However, better methodological quality studies demonstrating the effects attributed to him are still needed.

    To evaluate the bacterial contamination of bandage disposable soft contact lenses used in patients following photorefractive keratectomy (PRK) and to correlate our findings with clinical data. Forty-six patients (81 eyes) underwent PRK. Immediately after each procedure, disposable soft contact lenses were positioned with sterile forceps. After 3 days, the lenses were removed in a sterile manner, placed in sterile Eppendorf pipettes containing 8 mL of enriched brain heart infusion broth, and analyzed for microbial contamination. Seven positive cultures were found: six gram positive cocci (7.4%) and one gram negative bacillus (1.2%). There was no clinical correlation with these findings. Isolated microorganisms were similar to those described in the literature as agents of bacterial keratitis and are components of the normal ocular flora. Klebsiela pneumoniae--considered an occasional or transient flora--was the exception. All isolated microorganisms but K. pneumoniae were sensitive to most of the antibiotics tested. Our findings suggest that the risk of infectious keratitis after PRK related to soft contact lens wear for 3 days seems to be low, which may be because lenses were not manipulated by the patient during the wearing period, and the postoperative antibiotic regimen was strictly followed by patients. However, care should be taken to instruct patients in proper lens care practices to reduce the risk of bacterial keratitis in contact lens wear following PRK.

    Insomnia is a problem often experienced by patients on chronic dialysiswhich reduces their quality of life. Current management of insomnia with this specific group of patients has yet to produce optimum results. In this study, we explored the roleof acupuncture as a treatment for symptoms of insomnia in patients on chronic dialysis. Twenty-eight hemodialysis patients suffering from insomnia were divided randomly into two groups, an acupuncture group (n = 15) who received acupuncture treatment at the points HT7 Shenmen, PC6 Neiguan, GV20 Baihui, and EX-HN1 Sishenchong, anda control group (n = 13) who underwenta sham procedure in which a needle was inserted into an elastic bandage at the same points. The acupuncture treatment was done during hemodialysis twice a week for five weeks. PSQI scores and the WHOQOL-BREF were assessed before treatment, after the fifth treatment, and at the end of the treatment. Significant differences were found in the PSQI score ((4.20±2.27 vs. 11.23±3.37) p = 0.000) and in the WHOQOL-BREF ((94.53±10.08 vs. 82.69±11.90) p = 0.008) between the acupuncture group and the control group by the end of the period of treatment. Acupuncture treatment effectively improved the quality of sleep and the quality of life for these chronic hemodialysis patients.

    Tropical lowland on Nepal is at full of risk to snake bite. The snake bite mortality is due to lack of awareness about proper management of victims. The study aims to assess the change in the pattern of management of snake bite victims after first aid training. A retrospective study was done from October 2007 to October 2008 among 43 snake bite victims in rural Madi valley comprising of 4 village development committees where first aid training was conducted one year before. Only 26% of the snake bite victims approached traditional healer before arriving at the heath facility. The case fatality rate dropped to 22% after venomous snake bite. Pressure Immobilization bandaging and local compression pad immobilization technique was used by 56% who went to the health facility. Mean duration for reaching health facility was 61.51±33.55 minutes. Common places of bite were field 16 (37.2%), Indoor 6 (14%), while sleeping 6 (14%), and yard 6 (14%). Lower extremity bites were 32 (74.4%), upper extremity 8 (18.6%) and head 3 (7%). Bicycle was the commonest mode of transport 22 (51%) followed by ambulance 9(27.9%) and Motorcycle 6 (11%). First aid training changes the attitude of the people in management of snake bite victims and is one of the effective ways in decreasing mortality. Nationwide campaigning should be done especially at snake bite prone area about the proper first aid technique to improve the awareness level of the general population.

    Abstrat A 50-year-old female patient suffering from a severe form of epidermolysis bullosa acquisita (EBA) took legal action against the Croatian Pension Insurance Institute (CPII) in an attempt to overturn their assessment that she was no longer capable of working as a seamstress but still capable of doing administrative jobs. Her claim was that she was not capable of doing any job at all. She was first diagnosed EBA in 2000, and the disease progressed slowly with intermittent remissions. In 2012, skin erosions appeared on her feet, followed by the loss of all toenails and lesions and infiltrations on the tongue and oral mucosa. Her whole body was covered in oozing wounds, she was in pain, and parts of her skin would stick to fabric while changing clothes or bandages. The most recent findings showed oesophageal stricture. She can consume only liquid food and is on the waiting list for receiving a feeding tube. The occupational health expert witness confirmed that the patient was generally incapable of work and was fighting her life. The judge and CPII lawyers fully accepted this report and the earlier assessment was overturned. To avoid incompetent assessments of working (in)capacity in the future, CPII and similar institutions should engage occupational medicine specialists to work in their assessment teams.

    Nanocapsules, existing in miniscule size, range from 10 nm to 1000 nm. They consist of a liquid/solid core in which the drug is placed into a cavity, which is surrounded by a distinctive polymer membrane made up of natural or synthetic polymers. They have attracted great interest, because of the protective coating, which are usually pyrophoric and easily oxidized and delay the release of active ingredients. Various technical approaches are utilized for obtaining the nanocapsules; however, the methods of interfacial polymerization for monomer and the nano-deposition for preformed polymer are chiefly preferred. Most important characteristics in their preparation is particle size and size distribution which can be evaluated by using various techniques like X-ray diffraction, scanning electron microscopy, transmission electron microscopy, high-resolu¬tion transmission electron microscopy, X-ray photoelectron spectroscopy, superconducting quantum interference device, multi angle laser light scattering and other spectroscopic techniques. Nanocapsules possessing extremely high reproducibility have a broad range of life science applications. They may be applied in agrochemicals, genetic engineering, cosmetics, cleansing products, wastewater treatments, adhesive component applications, strategic delivery of the drug in tumors, nanocapsule bandages to fight infec¬tion, in radiotherapy and as liposomal nanocapsules in food science and agriculture. In addition, they can act as self-healing materials. The enhanced delivery of bio¬active molecules through the targeted delivery by means of a nanocapsule opens numerous challenges and opportunities for the research and future development of novel improved therapies.

    A wearable self-powered active sensor for respiration and healthcare monitoring was fabricated based on a flexible piezoelectric nanogenerator. An electrospinning poly(vinylidene fluoride) thin film on silicone substrate was polarized to fabricate the flexible nanogenerator and its electrical property was measured. When periodically stretched by a linear motor, the flexible piezoelectric nanogenerator generated an output open-circuit voltage and short-circuit current of up to 1.5 V and 400 nA, respectively. Through integration with an elastic bandage, a wearable self-powered sensor was fabricated and used to monitor human respiration, subtle muscle movement, and voice recognition. As respiration proceeded, the electrical output signals of the sensor corresponded to the signals measured by a physiological signal recording system with good reliability and feasibility. This self-powered, wearable active sensor has significant potential for applications in pulmonary function evaluation, respiratory monitoring, and detection of gesture and vocal cord vibration for the personal healthcare monitoring of disabled or paralyzed patients.

    Integration of electronics into materials and objects that have not been functionalized with electronics before, open up extensive possibilities to support mankind. By adding intelligence and/or operating power to materials in close skin contact like clothing, furniture or bandages the health of people can be monitored or even improved. Foil based electronics are interesting components to be integrated as they are thin, large area and cost effective available components Our developed technology of printed electronic structures to which components are reliably bonded, fulfills the promise. We have integrated these components into textiles and built wearable encapsulated products with foil based electronics. Foil components with organic and inorganic LEDs are interconnected and laminated onto electronic textiles by using conductive adhesives to bond the contact pads of the component to conductive yarns in the textile. Modelling and reliability testing under dynamic circumstances provided important insights in order to optimise the technology. The design of the interconnection and choice of conductive adhesive / underfill and lamination contributed to the durability of the system. Transition zones from laminated foil to textile are engineered to withstand dynamic use. As an example of a product, we have realized an electronic wristband that is encapsulated in rubber and has a number of sensor functionalities integrated on stretchable electronic circuits based on Cu and Ag. The encapsulation with silicone or polyurethanes was performed such, that charging and sensor/skin contacts are possible while simultaneously protecting the electronics from mechanical and environmental stresses.

    To examine possible etiology and treatment outcomes in 21 patients with glans necrosis following penile prosthesis implantation. Glans necrosis typically presented with a dusky glans on the first postoperative day following prosthesis implantation. The blood supply to the glans penis consists of the dorsal arteries and the terminal branches of the spongiosal arteries. Using the cohort in our study, we compiled preoperative comorbidities and adjunctive surgical maneuvers that might compromise glans vascularity, leading to glans necrosis. Preoperative risk factors were arteriosclerotic cardiovascular disease (90%), diabetes mellitus (81%), smoking (81%), previous prosthesis explantation (57%), and previous radiation therapy (48%). The most prevalent intraoperative and postoperative factor was subcoronal incision for reasons as simple as coincident circumcision or as complex as for penile degloving (86%). Other factors detected were penile wrapping with an occlusive elastic bandage (62%), use of a sliding technique for penile lengthening (33%), and coincident distal urethral injury repair (29%). Seventeen patients (81%) managed expectantly with preservation of implanted prosthesis sustained significant glandular loss. Four patients managed with immediate prosthesis removal healed without sequelae. Patients with preoperative risk factors undergoing penile prosthesis implantation should avoid high-risk adjunctive surgical maneuvers. Upon development of signs of glans necrosis postoperatively, in the setting of these high-risk factors, immediate implant removal may prevent subsequent glans necrosis. Copyright © 2017 Elsevier Inc.

    To describe a population of dogs affected by escalator-related injuries, and to characterize the types of injuries sustained and describe treatment administered. Retrospective study from March 2007 to November 2014. Large urban referral and emergency facility. Thirty client-owned dogs presenting with injuries acquired while riding an escalator. None. All injuries in this study occurred secondary to entrapment of 1 or more paws in the moving parts of an escalator; 39 paws were injured in total. The median body weight of the patients in this study was 4.25 kg, with 73.3% of the patients weighing less than 10 kg. Fifteen patients (50.0%) were treated surgically, the remainder were managed conservatively. Eight patients (26.7%) underwent digit or partial-digit amputation. Of the conservatively managed patients, 10 were treated with bandaging of the wounds. Antimicrobials, opiate analgesics, and nonsteroidal anti-inflammatory drugs were administered in both surgically and conservatively managed patients. While uncommon, escalator accidents can result in significant injury to dogs. Measures can be taken to prevent these injuries from occurring, whether through client education, dog training, structural modifications in the escalators themselves, or avoidance of escalators. In the present study, the survival rate of dogs injured on escalators was 100%. © Veterinary Emergency and Critical Care Society 2017.

    To report a case of corneal hydrops with perforation in a patient with ectasia after undergoing laser in situ keratomileusis (LASIK). An observational study with clinical, optical coherence tomographic, and histopathologic findings. A 41-year-old woman had an acute onset of blurry vision, pain, photophobia, tearing, and foreign body sensation in the right eye 10 years after undergoing unilateral LASIK in Jordan. According to her, the surgeon elected not to operate on the left eye because of a "corneal abnormality." On slit-lamp examination, a tear in Descemet membrane with a stromal cleft extending to the overlying LASIK flap interface was noted. The flap was partially dehisced by a diffuse channel of aqueous humor draining from the cleft and streaming out the temporal flap edge. When leakage failed to stop after 2 weeks of treatment with a bandage contact lens, the patient underwent penetrating keratoplasty. Histopathological examination of the host button showed a fluid-filled cleft connecting the flap interface. Slit-lamp examination and corneal topography of the contralateral left eye were consistent with keratoconus. Corneal hydrops with perforation in the setting of post-LASIK ectasia is extremely rare and may be associated with flap dehiscence requiring penetrating keratoplasty.

    Insufficiency fracture is a type of stress fracture that occurs when stress is applied to the bone with less than the normal elastic resistance, as in osteoporosis. Insufficiency fracture of the sternum is rare among all kinds of fractures. We describe two cases with insufficiency fractures of the sternum secondary to osteoporosis and thoracic kyphotic deformity. Both of the present cases, a 76-year-old woman and a 65-year-old woman, presented with severe anterior chest pain simulating myocardial infarction. However, cardiopulmonary examinations including chest radiographs, electrocardiograms, and laboratory tests were normal. Lateral radiographs of the sternum in both patients showed insufficiency fractures of the sternum. Conservative treatment with rib bandaging/bracing and analgesics relieved their symptoms. Clinical behavior, type of sternal insufficiency fractures, and mechanism of the fracture are reviewed from perusal of the literature. We emphasize that sternal insufficiency fracture should be considered in the differential diagnosis of acute chest pain in the elderly along with myocardial infarction or pulmonary embolism.

    Significance: Chronic wounds represent a major burden on global healthcare systems and reduce the quality of life of those affected. Significant advances have been made in our understanding of the biochemistry of wound healing progression. However, knowledge regarding the specific molecular processes influencing chronic wound formation and persistence remains limited. Recent Advances: Generally, healing of acute wounds begins with hemostasis and the deposition of a plasma-derived provisional matrix into the wound. The deposition of plasma matrix proteins is known to occur around the microvasculature of the lower limb as a result of venous insufficiency. This appears to alter limb cutaneous tissue physiology and consequently drives the tissue into a ‘preconditioned’ state that negatively influences the response to wounding. Critical Issues: Processes, such as oxygen and nutrient suppression, edema, inflammatory cell trapping/extravasation, diffuse inflammation, and tissue necrosis are thought to contribute to the advent of a chronic wound. Healing of the wound then becomes difficult in the context of an internally injured limb. Thus, interventions and therapies for promoting healing of the limb is a growing area of interest. For venous ulcers, treatment using compression bandaging encourages venous return and improves healing processes within the limb, critically however, once treatment concludes ulcers often reoccur. Future Directions: Improved understanding of the composition and role of pericapillary matrix deposits in facilitating internal limb injury and subsequent development of chronic wounds will be critical for informing and enhancing current best practice therapies and preventative action in the wound care field.

    Venous ulcers are the most common ulcers of the lower limb. It has a high morbidity and results in economic strain both at a personal and at a state level. Chronic venous hypertension either due to primary or secondary venous disease with perforator paucity, destruction or incompetence resulting in reflux is the underlying pathology, but inflammatory reactions mediated through leucocytes, platelet adhesion, formation of pericapillary fibrin cuff, growth factors and macromolecules trapped in tissue result in tissue hypoxia, cell death and ulceration. Duplex scan with colour flow is the most useful investigation for venous disease supplying information about patency, reflux, effects of proximal and distal compression, Valsalva maneuver and effects of muscle contraction. Most venous disease can be managed conservatively by leg elevation and compression bandaging. Drugs of proven benefit in venous disease are pentoxifylline and aspirin, but they work best in conjunction with compression therapy. Once ulceration is chronic or the patient does not respond to or cannot maintain conservative regime, surgical intervention treating the underlying venous hypertension and cover for the ulcer is necessary. The different modalities like sclerotherapy, ligation and stripping of superficial varicose veins, endoscopic subfascial perforator ligation, endovenous laser or radiofrequency ablation have similar long-term results, although short-term recovery is best with radiofrequency and foam sclerotherapy. For deep venous reflux, surgical modalities include repair of incompetent venous valves or transplant or transposition of a competent vein segment with normal valves to replace a post-thrombotic destroyed portion of the deep vein.

    The amniotic membrane (AM) is the innermost layer of the fetal membranes (placenta), widely used in transplantation being a tissue that combines anti-inflammatory, antimicrobial and antifibrotic, and limited immunogenicity. The tissue can be used a bandage biological for treatment of burns and skin wounds, chronic ulcers, reconstructions from different body areas, including ophthalmic repairs. In the last decades the amniotic membrane has been used widely also as a carrier substrate to transfer tissues cultured 'in vitro'. The use of fresh membrane has some limitations, the main ones are being necessary your quick use and the inability to obtain full security for certain infections. Other types of preservation require a processing thereof. The radiosterilization is an alternative for ensuring quality and safety of tissues used in transplants, and other clinical applications in order to minimize the risk of contamination of the receptor tissue. Therefore, the objective of this study was to test various doses of radiation using two sources of ionizing radiation: the cobalt-60 irradiator Gamma and Electron Beam Accelerator (E.B.). A tissue analysis was done by visual and tactile qualitative analysis, semi-quantitative (solid colorimetry) and light microscopy to observe morphological and physic-chemical changes after the irradiation of AM preserved in glycerol, comparing the results obtained with the sample not irradiated. It was noted that at higher doses, for both radiation sources, irradiated membranes suffered greater color change, becoming yellowish and thereby reducing their initial malleability. (author)

    Full Text Available The case presented here points towards the fact that skin lesion observed with a cowpox virus is a rare event but should be considered more as the number of cases has increased in the last years. Cowpox virus (CPXV belongs to the Poxviridae family. The transmission of CPXV to humans is caused by wild rodents or mostly by domestic animals and pet rats. In humans, CPXV is responsible for localized skin lesions regularly accompanied by lymphadenopathy. The lesions remain localized but self-inoculation from the primary lesions could occur. Then physicians have to be vigilant concerning bandages. In this case report, a necrotic and ulcerated lesion of a CPXV infection in a young boy is reported. The CPXV was possibly transmitted by wild rodents. The importance of performing the diagnosis is also pointed out. Virus information was obtained from phylogenetic analyses showing that the CPXV isolate was distinct from outbreaks of human cowpox which occurred in 2009 in France and Germany but was close to the CPXV Brighton Red strain. For several years, cases of viral zoonosis caused by CPXV have increased and physicians should be made aware that people could be infected without history of direct contact with animals.

    2017-01-01

    Full Text Available An 18-year old intact female Bactrian camel (Camelus bactrianus was suffering from lameness due to a mass on the right dorsal metacarpal region that caused acute swelling and local skin necrosis. Histology examination and immunohistochemistry of the biopsy material of a mass revealed haemangiosarcoma of the extensor tendons. Three weeks after the biopsy, the tumour was enlarged to 6 cm in diameter and the animal became disabled. The tumour with its associated tendon were resected and the tendon’s edges were bridged with a synthetic polytape graft. The camel was fully weight-bearing after the surgery. Two weeks later, the graft was removed due to widespread necrosis. Since the wound was positive for Corynebacterium sp., Acinetobacter iwoffii, Micrococcus sp., Escherichia coli, and Staphylococcus sp., the post-operative antibiotic treatment was prolonged for 28 days. Four months later, the wound healed using daily irrigation and bandaging and the camel walked normally. Nine months after diagnosis, the camel suddenly died without any clinical signs. Metastases of the haemangiosarcoma were found in the liver, lungs, kidneys, brain, meninges, and mediastinum. Exsanguination due to rupture of a liver metastasis was determined as the cause of the death. Haemangiosarcoma is a malignant neoplasm that arises from endothelial cells of blood vessels and tends to be very aggressive. To the author’s knowledge, this is the first case report of a metastasizing haemangiosarcoma arising from the lateral extensor tendon in a Bactrian camel.

    Full Text Available Neuroosteoarthropathy is a rare, but devastating complication affecting patients with peripheral neuropathy. It is a progressive, destructive condition that is characterised by progressive bone and joint deterioration of the foot leading to permanent incapacity. Nowadays, diabetes mellitus is by far the most common etiology of CNO (Charcot neuro-osteoarthropathy, especially if it affects the foot or ankle.The cause of the condition is still controversial among experts. In particular, new data have emerged on the central role of RANK/RANKL/OPG in the pathogenesis of this complication, also known as Charcot foot. No pharmacological methods of therapy have proven effective to date. Very little progress has been made in treating this condition since the days of Jean-Martin Charcot. Today, the universally accepted treatment involves completely relieving pressure from the limb using a polymer retaining bandage. The aim of this review is to analyze research into the pathogenesis of CNO and our potential to better understand the nature of this condition.Particular attention is paid to modern concept of neuroosteopathology, according to which neuropathy is crucial to developing acute osseous pathology. Revealing new aspects of CNO pathogenesis can help extend therapeutic resources for treating this patient group.

    The objective of this study was to assess the effectiveness of graduated compression socks (GCS) on enhancing muscle blood flow and oxygenation during exercise and recovery in healthy subjects. Twelve healthy volunteers completed a protocol involving baseline, exercise, and recovery periods with and without GCS. Each test was repeated twice to assess repeatability of the results. The applied sock pressure was measured prior to experimentation using a custom pressure sensing system, and modified as necessary using tensor bandages to control the applied load. During each of the experimental phases, blood velocity in the popliteal artery, calf muscle tissue oxygenation, muscle activity, heart rate, blood pressure, cardiac output, and applied pressure from the sock were measured. Popliteal artery diameter was measured during baseline and recovery periods. The GCS significantly reduced deoxyhemoglobin (HHb) in the leg during baseline (HHb, p = 0.001) and total blood volume and HHb in the leg during exercise (total hemoglobin, p = 0.01; HHb, p = 0.02). However, there were no differences in leg muscle blood flow velocity or any other variables with and without GCS at baseline, exercise, or recovery. Interestingly, it was found that the local applied sock pressure was very sensitive to the sock application process and, furthermore, the pressure varied considerably during exercise. No significant changes were observed in measures reflecting oxygen delivery for healthy subjects using GCS during exercise and recovery. Applied sock pressure was carefully controlled, thus eliminating the sock application process as a variable.

    To obtain in vivo data about intra- and extra-articular knee temperatures to assess the effectiveness of two cryotherapeutic methods-conventional cooling with gel-packs and computer controlled cryotherapy following anterior cruciate ligament (ACL) reconstructive surgery. Twenty patients were arbitrarily assigned for cryotherapy after ACL reconstruction: 8 patients with frozen gel-packs and 12 patients with computer controlled cryotherapy with constant temperatures of the cooling liquid in the knee pads. The treatment was performed for 12 h. Temperatures were measured with two thermo sensors in catheters placed intraarticularly and subcutaneously, four sensors on the skin and one sensor under protective bandage, every second for 16 h after surgery. In the first 2 h of treatment, there were no significant differences (n.s.) between the groups in temperatures in the intracondylar notch. After 4 h of cryotherapy, the temperatures were significantly lower on the skin (24.6 ± 2.8 and 31.4 ± 1.3 °C, p cryotherapy group compared to the gel-pack group. The cooling effect of the arthroscopy irrigation fluid on the knee temperature is evident in the first 2 h of treatment. The energy extraction is significantly more effective and controllable by computer controlled cryotherapy than with frozen gel-packs. Prospective comparative study, Level II.

    To report treatment of a comminuted ulnar carpal (UC) bone fracture associated with carpal instability by pancarpal arthrodesis using 2 locking compression plates (LCP). Case report. A 2-year-old Thoroughbred filly. An UC fracture and luxation of the proximal row of carpal bones was diagnosed radiographically. Pancarpal arthrodesis was performed with 2 LCP positioned dorsolaterally and dorsomedially and centered over the carpus through a single skin incision. The filly was maintained in a full limb cast for 15 days, followed by a tube cast for 14 days, and subsequently a full limb bandage with caudal splint for 21 days. Two LCP provided appropriate carpal stability resulting in a pasture sound horse 6 months after surgery. The filly was discharged from the hospital 63 days after surgery, walking well with only a slight mechanical lameness. Use of 2 LCP applied on the dorsomedial and dorsolateral aspect of the carpus can provide carpal stability for pancarpal arthrodesis. Excellent stability of the carpal joints can be achieved with 2 LCP.

    Full Text Available PURPOSE: To describe the outcome of various treatment modalities in the management of late bleb leaks after glaucoma filtering surgery (GFS. MATERIALS AND METHODS: Seven consecutive patients treated for late bleb leaks (Seidel′s positive between July 1990 and June 1999 were were enrolled in the study. The management strategy consisted of initial conservative therapy, and tailored surgery, if necessary. The surgical technique employed was either conjunctival-Tenon′s advancement flap, hinged scleral flap, or fistulectomy with direct suturing. The main outcome measures were bleb characteristics and postoperative intraocular pressure (IOP. The secondary outcome measure was visual acuity. RESULTS: One patient responded to conservative therapy (aqueous suppressants, bandage contact lens and six patients needed surgery. The successful surgical technique was conjunctivo-Tenon′s advancement flap in three, hinged scleral flap in two, and fistulectomy-direct suturing to the wound (combined with cataract surgery and intraocular lens implantation in one patient. The bleb leak stopped in all cases and 5 of the 6 surgical patients sustained functioning filtering blebs. Follow-up ranged from 8 to 56 months (mean = 20.4 +/- 16.2 months. Visual acuity improved to 6/12 or better in 4 cases, 6/36 in 2 cases and it remained at light perception in one case. None of the patients had any intraoperative or postoperative complications. CONCLUSIONS: Late leaking blebs after GFS can be treated successfully. The management decision and selection of surgical technique should be based on the clinical condition.

    To evaluate the extent and agents of bacterial contamination of bandage disposable soft contact lenses after laser subepithelial keratectomy (LASEK) and to correlate the findings with clinical data. Disposable soft contact lenses were collected from 52 eyes of 26 consecutive patients treated with LASEK for myopia. The patients were treated with a fixed combination of tobramycin and diclofenac until epithelial closure. The lenses were removed on the fourth or fifth postoperative day with sterile forceps and immediately placed in sterile tubes containing culture media brain-heart infusion broth. The lenses were evaluated for microbial colonization. Of the 52 contact lenses analyzed, six (11.5%) had positive cultures. However, no clinical finding of infection was noted. Isolated microorganisms were coagulase-negative staphylococci (two lenses), Stenotrophomonas maltophilia (two lenses), Acinetobacter species (one lens), and Aeromonas hydrophila (one lens). Except for one case, the microorganisms were sensitive to the administered antibiotic. The risk of infectious keratitis after LASEK seems to be low. Except for staphylococci, the isolated microorganisms have not been previously reported to colonize the ocular surface or cause keratitis after refractive surgery. These findings may suggest a changing trend of potentially infectious agents after surface ablation.

    In December 1913, a board of medical officers was appointed to adapt new U.S. Army equipment to the needs of the Hospital Corps. One of the improvements concerned substitution of the satchel-like Hospital Corps pouch used to carry first aid equipment. A waist belt with 10 pockets, known as the medical belt, was devised, and supplied with a tourniquet, adhesive plaster, safety pins, iodine swabs, sublimated gauze, individual dressing packets, gauze bandages, aromatic spirit of ammonia, and common pins. In addition, an ax carrier accommodating a hand ax, a canteen hanger, and a pouch to carry diagnosis tags and instruments were attached to the medical belt. In 1916, the medical belt was incorporated in the field supply tables in the Manual for the Medical Department. The next year, on April 6, 1917, the U.S. Congress declared war on Germany in reaction to sinking of American ships by German submarines. Although the medical belt had given satisfaction in preliminary trials, it did not withstand the test of war. In practice, the medical belt proved a source of dissatisfaction both as to the methods of packing and its contents, which were considered useless in modern warfare. Subsequently, discontinuance of the medical belt was recommended. Reprint & Copyright © 2016 Association of Military Surgeons of the U.S.

    Full Text Available Neurotrophic keratitis (NK is a rare degenerative disease of the cornea caused by an impairment of corneal sensory innervation, characterized by decreased or absent corneal sensitivity resulting in epithelial keratopathy, ulceration, and perforation. The aetiopathogenesis of corneal sensory innervation impairment in children recognizes the same range of causes as adults, although they are much less frequent in the pediatric population. Some extremely rare congenital diseases could be considered in the aetiopathogenesis of NK in children. Congenital corneal anesthesia is an extremely rare condition that carries considerable diagnostic and therapeutic problems. Typically the onset is up to 3 years of age and the cornea may be affected in isolation or the sensory deficit may exist as a component of a congenital syndrome, or it may be associated with systemic somatic anomalies. Accurate diagnosis and recognition of risk factors is important for lessening long-term sequelae of this condition. Treatment should include frequent topical lubrication and bandage corneal or scleral contact lenses. Surgery may be needed in refractory cases. The purpose of this review is to summarize and update data available on congenital causes and treatment of corneal hypo/anesthesia and, in turn, on congenital NK.

These lenses are fitted to not touch the cornea and there is a space created between the cornea and the lens. These lenses are inserted in the eyes after filling with sterile isotonic fluid. Generally, scleral contact lenses are used for high irregular astigmatism as seen in various corneal ectatic diseases such as keratoconus, pellucid marginal degeneration, or/and as liquid bandage in ocular surface disorders. In this article, we review the new developments, that have taken place over the years, in the field of scleral contact lenses as regard to new designs, materials, manufacturing technologies, and fitting strategies particularly for keratoconus.

    The opportunistic pathogen Staphylococcus aureus is known to interfere with wound healing and represents a significant risk factor for wound infections and invasive disease. It is generally assumed that one individual is predominantly colonized by one S. aureus type. Nevertheless, patients with the genetic blistering disease epidermolysis bullosa (EB) often carry multiple S. aureus types. We therefore investigated whether different S. aureus types are present in individual wounds of EB patients and, if so, how they are spatially distributed. The staphylococcal topography in chronic wounds was mapped by replica-plating of used bandages and subsequent typing of S. aureus isolates. Individual chronic wounds of five patients contained up to six different S. aureus types. Unexpectedly, distinct S. aureus types formed micro-colonies that were located in close proximity and sometimes even overlapped. While some adjacent S. aureus isolates were closely related, others belonged to distinct molecular complexes. We conclude that the general assumption that one individual is predominantly colonized by one type of S. aureus does not apply to chronic wounds of EB patients. We consider this observation important, not only for EB patients, but also for other patients with chronic wounds in view of the potential risk for severe staphylococcal infections.

    An 18-year-old woman was referred with late sequelae of chloroquine-induced Steven-Johnson syndrome. At the time of presentation, the symblepharon was involving the upper lids to almost the whole of the cornea, and part of the lower bulbar conjunctiva with the lower lid bilaterally. Other ocular examinations were not possible due to the symblepharon. B-scan ultrasonography revealed acoustically clear vitreous, normal chorioretinal thickness, and normal optic nerve head, with an attached retina. Conjunctivo-corneal adhesion released by superficial lamellar dissection of the cornea. Ocular surface reconstruction was carried out with a buccal mucous membrane. A bandage contact lens was placed over the cornea followed by the symblepharon ring to prevent further adhesion. The mucosal graft was well taken up along with corneal re-epithelization. Best corrected visual acuity of 20/120 in both sides after 1 month and 20/80 after 3 months was achieved and maintained till the 2.5-year follow-up.

    Full Text Available Driven by the need to engineer robust surface coatings for medical devices to prevent infection and sepsis, incorporation of nanoparticles has surfaced as a promising avenue to enhance non-fouling efficacy. Microbial synthesis of such nanoscale metallic structures is of substantive interest as this can offer an eco-friendly, cost-effective and sustainable route for further development. Here we present a Mucor hiemalis-derived fungal route for synthesis of silver nanoparticles, which display significant antimicrobial properties when tested against six pathological bacterial strains (Klebsiella pneumonia, Pseudomonas brassicacearum, Aeromonas hydrophila, Escherichia coli, Bacillus cereus and Staphylococcus aureus and three pathological fungal strains (Candida albicans, oxysporum, and Aspergillus flavus. These antimicrobial attributes were comparable to those of established antibiotics (streptomycin, tetracycline, kanamycin and rifampicin and fungicides (amphotericin B, fluconazole and ketoconazole, respectively. Importantly, these nanoparticles show significant synergistic characteristics when combined with the antibiotics and fungicides to offer substantially greater resistance to microbial growth. The blend of antibacterial and antifungal properties, coupled with their intrinsic green and facile synthesis, makes these biogenic nanoparticles particularly attractive for future applications in nanomedicine ranging from topical ointments and bandages for wound healing to coated stents.

    Full Text Available Background: The conventional technique of free non-vascularized fibular grafting is attended with some amount of morbidity and a long scar. We report a technique with little interference to the surrounding soft tissues to harvest more than one-third of whole length fibula. Patients and Methods: Thirty four patients of average age 23.5 years (range 8 to 51 years having various pathologies like simple bone cysts (n=9, fibrous dysplasias (n=6, giant cell tumors (n=7, fracture non-union (n=10 and aneurysmal bone cysts (n=2 were taken up for the study. The fibula were harvested by two separate incisions, 1 cm each at proximal and distal extent of proposed donor site for taking out of graft after elevating the periosteum circumferentially using a periosteum stripper. Compression bandage and above knee plaster immobilization was applied to reduce the dead space collection . Results: The mean followup is 34 months. The patients were evaluated clinicoradiology. Thirty three patients showed good results. One patient had fair result due to delayed wound healing from hematoma which was treated surgically. Conclusion: The approach of harvesting fibula suggested by author reduces donor site morbidity and is safer than conventional approach.

    We aimed to compare the effectiveness of immobilization in abduction and external rotation vs immobilization in adduction and internal rotation after primary anterior dislocation of the shoulder. The study randomized 102 patients (age range, 15-55 years) with the diagnosis of primary anterior dislocation of the shoulder to receive immobilization in adduction and internal rotation (AdIR, n = 51) using sling and swathe bandage or immobilization in abduction and external rotation (AbER, n = 51) with a stabilizer brace. Patients received a rehabilitation program 3 weeks after the intervention. After a 24-month follow-up, 33.3% in the AdIR group and 3.9% in the AbER group had recurrence (P patients in the AbER group (19.6%) and 3 in the AdIR group (5.8%) discontinued shoulder immobilization before 3 weeks (P = .03). In patients without recurrence, the anterior apprehension test was positive in 6 of 34 in the AdIR group (17.6%) and in 4 of 49 in the AbER group (8.1%, P = .19). Immobilization with the shoulder joint in abduction and external rotation is an effective method to reduce the risk of recurrence after primary anterior shoulder dislocations and should be preferred to the traditional method of immobilization in adduction and internal rotation in clinical practice.

    To investigate the effects and mechanisms of Gong-tone music on the immunological function in rats with the Chinese medicine syndrome of Liver (Gan)-qi stagnation and Spleen (Pi)-qi deficiency (LSSD). Twenty five male Wistar rats of SPF grade were randomly divided into 5 groups: normal group, model group, Xiaoyao Powder () group, Gong-tone group and combined group (the combination of Gong-tone and Xiaoyao Powder), with 5 rats in each group. The rat model for the Chinese medicine syndrome of LSSD was induced by chronic bandage and irregular diet. The course of treatment was 21 days. After the treatment, the levels of serum gastrin and IgG were detected by enzyme-linked immunoabsorbent assay (ELISA). Phagocytosis of macrophages was detected by the neutral red uptake assay and T cell proliferation was investigated by 3-(4,5-dimethylthiazolyl)-2,5-diphenyltetrazolium bromide (MTT) assay. The serum gastrin, macrophage phagocytosis, IgG level and proliferation ability of T cells in the model group were significantly decreased compared with those in the normal group (P music may upregulate the immunological function and play a role in adjuvant therapy in the Chinese syndrome of LSSD.

    On the battlefield, insidious and devastating weapons like the improvised explosive device (IED) rapidly emit extreme heat (thousands of degrees), create a shock wave (overpressure) that can hurl bodies long distances (inducing secondary fall lesions), and deliver thousands of pieces of shrapnel over hundreds of meters. Very often, Soldiers injured by an IED blast are inside their vehicle. Subsequently, they are exposed to the thermal effects of the blast. Frequently, these patients have complex wounds that consist of extensive burn areas, bone fractures, and internal organ lesions. The use of silver-nylon burn wrap dressing is widely documented for its bactericidal properties. Silverlon® Burn Dressings is an elastic bandage made of nylon and plated with pure metallic silver. In summer 2008, in a U.S. advanced Role 2 facility, two U.S. Soldiers with extensive second- and third-degree burn injuries were successfully treated with the use of Silverlon Burn Dressings and Silverlon® Burn Gloves. From this experience emerged the ease of use silver-nylon dressing in treating badly burned Soldiers on the battlefield. 2014.

    To describe the management and successful outcome of a late-recognition partial thickness bleach burn to the face and corneas of a dog. A 1-year-old male neutered Fox Terrier mix breed dog was evaluated for sloughing facial epithelium 5 days after coming into contact with an 8.25% household bleach cleaning solution. Severe erythema, edema, and crusting were noted around the muzzle and margins of both eyes, with moderate to severe alopecia in these areas. A partially detached, partial thickness eschar was present on the muzzle, while a firmly attached eschar was present in the region of both frontal sinuses. These injuries were consistent with a focal, superficial, and partial thickness chemical burn. Multiple ocular abnormalities, the most concerning of which was corneal ulceration, were also present. The patient's wounds were managed conservatively with limited surgical debridement of the affected epithelium 11 and 22 days after the initial exposure. Topical ocular medications, corneal debridement, and a superficial keratectomy were also used. All lesions resolved completely by 84 days postexposure, with no residual effects on the patient's quality of life. Chemical burns caused by contact with alkaline agents such as bleach (sodium hypochlorite) result in extensive necrosis of the skin and underlying structures. This is the first report of management alkaline facial burns in a dog. If inadequate or delayed hydrotherapy following exposure has resulted in superficial partial thickness burns, conservative management can be successful when traditional treatments, especially bandaging, are not feasible. © Veterinary Emergency and Critical Care Society 2017.

    Disuse-induced skeletal muscle atrophy is a serious concern; however, there is not an effective mouse model to elucidate the molecular mechanisms. We developed a noninvasive atrophy model in mice. After the ankle joints of mice were bandaged into a bilateral plantar flexed position, either bilateral or unilateral hindlimbs were immobilized by wrapping in bonsai steel wire. After 3, 5, or 10 days of immobilization of the hip, knee, and ankle, the weight of the soleus and plantaris muscles decreased significantly in both bilateral and unilateral immobilization. MAFbx/atrogin-1 and MuRF1 mRNA was found to have significantly increased in both muscles, consistent with disuse-induced atrophy. Notably, the procedure did not result in either edema or necrosis in the fixed hindlimbs. This method allows repeated, direct access to the immobilized muscle, making it a useful procedure for concurrent application and assessment of various therapeutic interventions.

    1997-04-01

    Latex sensitivity is a problem for many healthcare professionals. Latex is found in numerous items that a healthcare professional uses on a daily basis, including gloves, tapes, bandages, and catheters. Latex sensitivity can appear as a mild, localized contact reaction, or, in extreme cases, have more sever, systemic effects. Latex not only has the potential to affect a healthcare professional's career, but it can also adversely affect the healthcare professional's life. Several agencies have responded to the increased prevalence of latex-related illnesses, including the Food and Drug Administration and the Centers for Disease Control and Prevention. Lack of a national database and l lack of a government policy mandating the labeling of latex-containing products are just some of the problems that hinder latex research. While there are many unanswered questions regarding latex sensitivity, there are several steps that a healthcare professional can take to protect himself or herself from latex. These include: proper documentation and treatment, preventive measures such as wearing a medical alert tag or bracelet, finding and using latex alternatives in the workplace, and setting up official latex policies within their facilities.

    Lipedema is a common but rarely diagnosed disease or frequently confused with obesity. Patients are almost exclusively women. It is characterised by symmetrical, circumscribed, in advanced form deforming fat tissue accumulation on the legs that is associated with lymphedema. Spontaneous pain, pain to pressure and tendency to hematoma are characteristic. One of the possible causes of a fat leg, that is a very common complaint, is lipedema. Main differential diagnoses are obesity, lipohypertrophy and primary and secondary lymphedema. It is often associated with chronic venous and lymphatic insufficiency, early degenerative articular disease and obesity. The disease is rarely recognized and the treatment modalities are not widely known. Therefore patients feel very frustrated that leads to psychologic disorders. Until recently only conservative treatment was possible (combination of manual or intermittent pneumatic drainage, compression bandages and garments and physiotherapy). More recently surgical intervention (liposuction) is also included in the treatment options. The significance of lipedema is due not only to the disease itself, but also to the combination of lipedema and the group of associated and secondary diseases (articular and venous diseases, lymphedema, obesity, psychologic disorders). The more diseases coexist, the worse is the prognosis of lipedema itself. To prevent and delay this disease, it is indispensable to recognise it as early as possible and to treat it expertly and follow up patients suffering from lipedema.

    Lipedema is a disproportional obesity featuring frequent hematoma formation due to even minor traumatic injuries. On the basis of clinical observations, complete decongestive physiotherapy diminishes the incidence of hematomas due to minor injuries beyond leg volume reduction. Hematoma development may be caused by altered capillary resistance (CR) or altered capillary fragility (CF). We measured capillary fragility (CF) before and after complex decongestive physiotherapy (CDP) to examine, whether CDP could reduce CF. 38 women with lipedema were included in the study. Twenty-one (21) patients were treated with CDP and 17 using exclusively moisturizers as the control group. CDP comprised once daily manual lymph drainage, intermittent pneumatic compression and multilayered short-stretch bandaging performed throughout a 5-day-course. CF was evaluated with the vacuum suction method (VSM) using Parrot's angiosterrometer in both groups. Decongestive therapy resulted in a significant reduction of the number of petechiae while no change was detected within the control group. Complete decongestive physiotherapy significantly reduced CF in patients with lipedema and this reduction may lead to reduced hematoma formation.

    Lipedema is a disproportional obesity featuring light pressure-induced or spontaneous pain. On the basis of our clinical observations, lymphedema therapy, as practiced in our clinic, reduces the perception of pain beyond leg volume reduction. We therefore aimed to measure pain intensity prior and subsequent to treatment. 38 women with lipedema were enrolled in the study with 19 patients undergoing treatment and 19 serving as the control group using exclusively moisturizers. Treatment consisted of once daily manual lymph drainage (MLD), intermittent pneumatic compression (IPC), and multilayered short-stretch bandaging performed throughout a 5-day-course. Pain was evaluated with a 10-item questionnaire, a pain rating scale (PRS), and the Wong-Baker Faces scale. Treatment resulted in a significant reduction of pain with a decrease in mean scores of all three measures. In the control group, only PRS showed significant decrease. Our study results indicate that this treatment regimen not only reduces leg volume and capillary fragility, but also improves pain intensity in patients with lipedema.

    2009-01-01

    Auricular hematoma and cauliflower deformation of the ear are unique in several respects. Knowledge about it began, in antiquity, through artists, particularly Greek and Roman, and then Japanese in the 18th century with their representation of cauliflower deformation of the ear on sculptures and paintings of pugilists and wrestlers. It is only in the 19th century that physicians began to make substantive progress in understanding this abnormality. It was first thought to be associated with mental disease, but by the beginning of the 20th century, its etiology was recognized as being caused by trauma and was then named auricular hematoma. The second step in the understanding of this affliction was the observation that auricular hematoma progresses toward cauliflower deformation of the ear, which was named cauliflower ear. Recognition of this evolution led to the development of therapies. During the second half of the 20th century, different treatments were developed. They included various hematoma drainage techniques with special bandages to prevent hematoma recurrence and ensuing progression to cauliflower ear. In summary, cauliflower deformation of the ear is an old artistic affliction that has only recently received medical attention.

    Full Text Available Wound should be covered with bandage that is called wound dressing. Most people use synthetic materials such as gauze dressing. Gauze has high absorption of NaCl, which is often used to cleanse the wound. However, discomfort and pain arise since the gauze becomes sticky on the wound. Therefore, we need other alternatives instead of gauze to cover wound. One such alternative is the alginate membrane. This study used alginate membrane with mixture of mucous of the snail Achatina fulica, which contain proteins such as proline, serine asparagine, glycosaminoglycan, hydroxylysine, trionin and so forth, to activate the growth factor. Alginate powder and carboxymethl cellulose (CMC was dissolved in distilled water mixed with mucus of the snail Achatina fulica in four variations (4:0; 4:1, 4:2, 4:3 through a magnetic stirrer, and casted on a baking sheet covered with sterile gauze. High Performance Liquid Chromatography (HPLC test showed that the glycosaminoglycan content was found on the mucous of Achatina fulica. This was indicated by the appearance of peak at 325–350 second. The most optimum alginate and mucus composition was in ratio of 4:2. This ratio resulted in a wound dressing that was still able to absorb the exudate and optimally accelerated wound healing.

    In 1910, the surgeons Moreau and LePrince wrote about their successful operation on an eight-year-old boy who had been blind since birth because of cataracts. When the boy's eyes were healed they removed the bandages and, waving a hand in front of the child's physically perfect eyes, asked him what he saw. "I don't know," was his only reply. What he saw was only a varying brightness in front of him. However, when allowed to touch the hand as it began to move, he cried out in a voice of triumph, "It's moving!" He could feel it move, but he still needed laboriously to learn to see it move. Light and eyes were not enough to grant him sight. How, then, do we see? What's the difference between seeing and perception? What is light? From ancient times to the present, from philosophers to quantum physicists, nothing has so perplexed, so fascinated, so captivated the mind as the elusive definition of light. In Catching the Light, Arthur Zajonc takes us on an epic journey into history, tracing how humans have endeavore...

    AIM: To describe the radiological features and natural history of sub-aponeurotic fluid collections presenting after the neonatal period. MATERIALS AND METHODS: All cases of sub-aponeurotic scalp fluid collection presenting to the radiology department between June 1996 and June 2000 were reviewed. Note was made of the birth history, the radiographic and ultrasound features and the natural history (including any treatment) of the collection. RESULTS: Seven cases of sub-aponeurotic fluid collections were identified. There were six infants who presented 3{center_dot}5-18 weeks (mean nine weeks) after delivery, four of whom had had ventouse-assisted delivery. The last case was in a seven-year-old child who presented one month after minor head trauma. Clinical examination revealed non-tender, soft, mobile and fluctuant scalp swellings in all patients. Ultrasound identified sonolucent fluid collections of between 5 and 24 mm depth in the sub-aponeurotic space. No skull fractures were identified. Six patients were treated conservatively and one had fluid aspirated and a compression bandage applied. All cases resolved 2-24 weeks after diagnosis and there were no long-term sequelae. CONCLUSION: Sub-aponeurotic scalp collections presenting after the neonatal period are usually associated with ventouse-assisted delivery ultrasound is useful for diagnosis. The condition is benign and resolution occurs with conservative treatment. Hopkins, R.E. et al. (2002)

    Manual lymphatic drainage (MLD), intermittent sequential pneumatic therapy (ISPT), multilayered bandages (MLB), and compression garments are main techniques in conservative treatment of peripheral lymphedema. Since 1990, it has been thought that ISPT applied to both lower limbs simultaneously should not be used for patients with heart failure because right atrial, pulmonary arterial, and pulmonary wedge pressures may increase to a critical point. In 2005, these same results were observed in patients with heart failure wearing MLB. For these reasons, MLB and ISPT have been contraindicated during lymphedema treatment in cardiac patients. The aim of this study was to determine if we may continue the treatment of lower limb lymphedema using MLD in patients with heart failure. We evaluated hemodynamic parameters using echography during MLD in patients with cardiac disease and obtained circumferential measurements of the edematous limb before and after treatment. MLD treatment significantly decreased the limbs as expected. The heart rate also decreased following MLD in contrast with all other hemodynamic parameters which were not affected by MLD. The findings suggest that there is no contraindication to use MLD in patients with heart failure and lower limb edema.

    To determine if application of silver sodium zirconium phosphate polyurethane semi-occlusive foam (SPF) dressing would improve measures of wound healing and decrease bacterial contamination compared with a non-adherent, absorbent dressing applied to wounds created on the distal aspect of the equine limb. Controlled randomized experimental study. Adult Quarter Horse and Thoroughbred horses (n = 5). One 6.25 cm(2) wound was created on the dorsomedial aspect of the proximal metacarpus on each forelimb. A SPF dressing was applied to 1 randomly assigned limb as a treatment and a non-adherent, absorbent dressing was applied to the opposite limb as control. Bandages were changed every 3 days for 60 days. Granulation tissue was scored every 3 days, wound area measured every 6 days, and wound bed was cultured every 12 days. SPF-treatment wounds had significantly decreased wound area and decreased granulation tissue scores when evaluated dressing improved some measures of wound healing compared with the control dressing, most significantly during the first 30 days. This suggests that the SPF wound dressing may be useful in the early management of wounds on the equine lower limb. Further studies using the SPF dressing are needed to characterize the temporal and cellular effects on wound healing and evaluate this dressing in a clinical environment. © Copyright 2014 by The American College of Veterinary Surgeons.

    Full Text Available Keratitis without proper management tends to perforate the cornea, resulting in severe adverse consequences. In recent studies, amniotic membrane is reported to have anti-inflammatory effect and promote wound healing of corneal ulcer. Purpose: To report on the efficacy of permanent amniotic membrane transplantation (AMT in the treatment of keratitis. Case report: A 58-year-old man with severe keratitis in both eyes caused by long term administration of topical anesthetic (alcaine for electric ophthalmia. Single layer of amniotic membrane (AM was placed on the defect and secured to the limbus with interrupted 10-0 nylon sutures. A bandage contact lens was applied on the AM. Postoperative medication included topical antibiotic, artificial tears and mydriatic. Three months later corticosteroid was included. There was an immediate decrease of patient’s pain after surgery. Complete epithelialization was noted after 1 month. Conclusion: AMT is an alternative adjunctive method of treatment of keratitis; it promotes epithelialization process, decreased inflammation, corneal haze and neovascularization.

    This paper presents the results of a comprehensive investigation of the biological, microbiological, physico-chemical, and dosimetry aspects of using gamma irradiation for the sterilization of locally manufactured medical products and pharmaceuticals. The objective of this study is to determine the technological feasibility of radiation sterilization for the said products in the Philippines. Hence, the materials used were directly obtained from local manufacturers. They are polyvinyl chloride or polyethylene based medical plastic disposables namely: absorbent cotton, surgical gauze, bandage, visceral packs, and some antibiotics and opthalmic ointments. The gamma facility of the Philippine Atomic Energy Commission was used for the irradiation. Result of biological studies indicate no signs of toxicity on experimental mice injected with extracts from irradiated samples. The contaminants are identified as Pseudomonas Sp. Staphyloccocus Aureus and Bacillus Subtilis. The D 10 values of survivors of higher doses ranged below 0.235 Megarad suggesting that these contaminants can be eliminated by the generally used sterilizing dose of 2.5 Mrads. The physico-chemical tests did not indicate any significant degradation of the irradiated products. Opthalmic and topical antibiotic ointments showed no marked decrease in potency. Fading tests on dosimeters used showed that red perspex is a more efficient dosimeter than clear perspex when irradiation time is prolonged. These studies indicated that radiation sterilization is technically feasible for locally manufactured medical products.

    A prosthetist makes a conventional socket by wrapping plaster bandage around the residual limb and using the resulting shell to create a positive model. After he or she modifies the plaster, it is used to create a laminated socket. Such sockets are almost perfect cylinders that encapsulate the limb. The bone is centered in soft, compressible tissue that must move aside before the bone can push against the socket to transmit force or torque to the prosthesis. In a compression/release stabilized (CRS) socket, three or more longitudinal depressions compress and displace tissue between the socket wall and the bone to reduce lost motion when the bone is moved with respect to the socket. Release areas between depressions are opened to accommodate displaced tissue. Without these openings provided, the CRS socket will not function as intended. Often, the release areas of compression are the struts of a carbon-fiber frame, and the regions between struts are left open. A frame with openings may be modified by the prosthetist adding a thin membrane fully surrounding the limb but allowing the membrane and underlying tissue to enter the release openings. The membrane may contain electrodes, and it may constitute a roll-on liner that helps suspend the prosthesis. We introduce three socket designs: transradial, transfemoral, and transhumeral.

  8. Uterine culture in mares.

    A guarded, sterile swab is used to obtain samples for uterine culture. With the mare in stocks, the tail bandage and the perineum washed, the culture rod is introduced into the vagina with a gloved hand. After the rod is guided through the cervix, the guard cap is dislodged and the swab is rubbed along the endometrium, after which the rod is extracted. Samples for uterine culture should only be obtained during full estrus. Swabs should be directly plated onto agar within 2 hours of collection. Blood agar is appropriate for initial screening, but use of specialized types of agar expedites identification of microbes. Plates are incubated at 37 C and inspected for growth every 12 hours. The type and number of bacterial colonies should be coupled with the history and clinical signs in deciding on the necessity and type of treatment. Pure, heavy bacterial growth is usually accompanied by clinical signs of infection. Interpretation of the significance of moderate bacterial growth may be aided by cytologic examination of endometrial smears, made by rolling the swab onto a glass slide and staining with Diff - Quik . Large numbers of neutrophils indicate the need for antibiotic therapy. Mixed bacterial growth and variable numbers of neutrophils usually indicate faulty sampling technic. Microaerophilic or anaerobic cultures may aid diagnosis in cases of equivocal aerobic culture results.

    Full Text Available Introduction: Nanocapsules, existing in miniscule size, range from 10 nm to 1000 nm. They consist of a liquid/solid core in which the drug is placed into a cavity, which is surrounded by a distinctive polymer membrane made up of natural or synthetic polymers. They have attracted great interest, because of the protective coating, which are usually pyrophoric and easily oxidized and delay the release of active ingredients. Methods: Various technical approaches are utilized for obtaining the nanocapsules; however, the methods of interfacial polymerization for monomer and the nano-deposition for preformed polymer are chiefly preferred. Most important characteristics in their preparation is particle size and size distribution which can be evaluated by using various techniques like X-ray diffraction, scanning electron microscopy, transmission electron microscopy, high-resolution transmission electron microscopy, X-ray photoelectron spectroscopy, superconducting quantum interference device, multi angle laser light scattering and other spectroscopic techniques. Results: Nanocapsules possessing extremely high reproducibility have a broad range of life science applications. They may be applied in agrochemicals, genetic engineering, cosmetics, cleansing products, wastewater treatments, adhesive component applications, strategic delivery of the drug in tumors, nanocapsule bandages to fight infection, in radiotherapy and as liposomal nanocapsules in food science and agriculture. In addition, they can act as self-healing materials. Conclusion: The enhanced delivery of bioactive molecules through the targeted delivery by means of a nanocapsule opens numerous challenges and opportunities for the research and future development of novel improved therapies.

    Achillodynia is a generic term for various types of ailments in the region of the Achilles tendon. For adequate therapy a specific diagnosis is absolutely necessary. Besides an accurate anamnesis and the right choice of terrain and shoes, as well as a clinical examination where one has to specifically keep an eye on muscular imbalance between the gastrocnemius and the soleus muscle and disorders of the ligamentous control of the calcaneus caused by fibular ligament instabilities, a procedure such as radiology, ultrasound, and MR imaging is inevitable. From the differential diagnosis point of view a distinction between peritendinitis, mechanically triggered bursitis (calcaneal and subachilles), bony alterations of the calcaneus (calcaneus spur, Haglund exostosis persistent nucleus of the apophysis, fatigue fracture, etc) and a partial or total rupture (a one-time occurrence or multiple occurrences) has to be made. Occasionally, entrapment of the ramus calcaneus of the sural nerve causes calcaneal pain. If clinically not confirmed, lumbar pain ought to be taken into consideration (discopathy, Bechterew disease, etc). Metabolic disorders (especially uric acid) and underlying rheumatic diseases must be excluded. The therapy of achillodynia includes local and peroral antiphlogistic medication as a concomitant measure. More important is the causal influence of etiological factors, i.e., the correction of muscular imbalance, ensuring control of the calcaneus through bandages and adjustment of sport shoes, changes in training buildup and exercise intensity, just to mention a few. If necessary, surgically splitting the peritendineum, sanitation of a partial rupture, bursectomy and removal of mechanically obstructive exostosis must be done.

    The Dutch Emission Registration is an integral information system which contains data on the emissions of circa 900 materials of more than 700 businesses in the Netherlands. In this report attention is paid to how data from the Emission Registration can be presented such that specific groups of businesses and industrial sectors can be stimulated to reduce their emissions. Thereto, an index has been developed which gives an indication of the environmental load (emission in the year of registration) and the environmental performance (trends in emissions during a number of years) of groups of businesses and industrial sectors. Based on the results of a literature study six possible environmental indexes were investigated and compared for two randomly chosen groups of businesses (building materials, ceramics and glass industry and metal products industry) and two randomly chosen industrial sectors (fertilizer industry, and medicine and bandages industry). The indexes were calculated for the years 1988, 1990 and 1992. The index, which is based on a unweighted aggregation of emissions of a business group or industrial class, divided by the national emission and corrected for the number of laborers, appeared to be the most favorable. 9 refs.

    Girolamo Cardano was an experienced card player, but that night he was losing money at an alarming rate. No wonder, for he was being cheated. When he realized that the cards were marked, he drew his dagger and stabbed the cheat in the face. Cardano then forced his way out of the gambling den into the narrow streets of Venice, recovering his money on the way. Running for his life in complete darkness, he slipped and plunged into the muddy waters of a canal - not the best place to be if you cannot swim. It was sheer luck that he managed, somehow, to grab the side of a passing boat and was lifted to safety by a helpful hand. Once on the boat, however, Cardano faced a man with a bandaged face - the cheat himself. Perhaps it was the chill of the night that cooled their tempers, or perhaps neither of the two wanted trouble with the notoriously strict Venetian authorities, but there was no brawl. Instead, Cardano was given clothing and travelled back home in amiable conversation.

    Chronic wounds can take a long time to heal despite appropriate therapy based upon aetiology and use of suitable dressings. The success of electrostimulation is based upon the existence within the skin of the endogenous currents involved in the wound healing process. Where skin continuity is broken by a wound, these electrical potentials are short-circuited, resulting in leakage of electrical current. Woundel(®) therapy is the only such treatment currently available in France and is based on the use of continuous pulsed current that generates an electrical field near the endogenous electrical fields. It utilises a console to deliver the electrical impulses, a dressing electrode and a dispersion electrode. The electrode dressing is left on the wound for 3 days, and venous compression bandaging may be applied to the leg, taking care to leave the connector free. Negative polarity stimulates migration of fibroblasts, resulting in elimination of fibrin. Positive polarity causes keratinocyte migration, which in turn leads to epidermisation. Electrostimulation is of recognised utility in the healing of chronic wounds: it has been assigned a high-level recommendation in the European and American guidelines for the treatment of venous ulcers and bedsores with proof level of A. Further, the analgesic effect of electrostimulation has been demonstrated in several studies. Electrostimulation is already well developed in France among wound specialists, but prospective studies are planned so that it may be used at patients' homes. Copyright © 2015 Elsevier Masson SAS.

    Full Text Available Absorbency of textiles is defined as the ability of taking in a fluid in the manner of a sponge. Absorbency is required for comfort properties in so me clothes such as sportswear and underwear clothing, for drying properties in napkins, towels and bathrobes, for health concerns in some medical textiles such as bandages, gauze and absorbent cotton, and for cleaning properties in washclothes and mops. In this study five different fabric samples (three woven 100% cotton fabrics A, B and P respectively at plain, twill, and peshtamal weaving patterns and two 100% cotton terry towels T1 and T2 were tested. The absorbency properties of the samples were evaluated according to the droplet test, sinking time test and wicking height tests (pottasium chromate test. Peshtamal samples showed better absorbency results than plain and twill weaves and lower but close results to towel samples according to the droplet test, sinking time test and wicking height tests. The absorbency properties of peshtamals showed results close to towel samples. The void content of peshtamals is higher than plain and twill samples but closer and lower than towel samples. The good absorbency results of peshtamals might be due to the void content of peshtamals which is higher than plain and twill samples but closer and lower than towel samples. Peshtamals which are good in absorbency and light in weight might be used widespreadly in daily life for their high absorbency, and on travel for weight saving purposes.

  16. Venous ulcers of the lower limb: Where do we stand?

    2012-01-01

    Full Text Available Venous ulcers are the most common ulcers of the lower limb. It has a high morbidity and results in economic strain both at a personal and at a state level. Chronic venous hypertension either due to primary or secondary venous disease with perforator paucity, destruction or incompetence resulting in reflux is the underlying pathology, but inflammatory reactions mediated through leucocytes, platelet adhesion, formation of pericapillary fibrin cuff, growth factors and macromolecules trapped in tissue result in tissue hypoxia, cell death and ulceration. Duplex scan with colour flow is the most useful investigation for venous disease supplying information about patency, reflux, effects of proximal and distal compression, Valsalva maneuver and effects of muscle contraction. Most venous disease can be managed conservatively by leg elevation and compression bandaging. Drugs of proven benefit in venous disease are pentoxifylline and aspirin, but they work best in conjunction with compression therapy. Once ulceration is chronic or the patient does not respond to or cannot maintain conservative regime, surgical intervention treating the underlying venous hypertension and cover for the ulcer is necessary. The different modalities like sclerotherapy, ligation and stripping of superficial varicose veins, endoscopic subfascial perforator ligation, endovenous laser or radiofrequency ablation have similar long-term results, although short-term recovery is best with radiofrequency and foam sclerotherapy. For deep venous reflux, surgical modalities include repair of incompetent venous valves or transplant or transposition of a competent vein segment with normal valves to replace a post-thrombotic destroyed portion of the deep vein.

    2014-11-01

    A technique for making a provisional nasal prosthesis for interim use after the ablation of a midface tumor is described. The technique is especially useful for the re-creation of a nasal form in an expedient and cost-effective manner. A preoperative definitive cast, or moulage, of the patient that includes a nasal form is used to fabricate a vacuum form of the midface. The vacuum form is evaluated on the patient, the extension is adjusted, and an external adhesive knit liner is applied to give the appearance of a contoured nasal bandage. The provisional nasal prosthesis is attached with medical adhesive tape and removed daily by the patient. The prosthesis is easily replaced during the course of treatment and has been found to be functional and esthetically acceptable to those patients receiving care from the Dental Service at Memorial Sloan Kettering Cancer Center.

    We investigate the use of 2nd-generation High-Temperature Superconductors (2G-HTSs) in the rotors of electrical motors and generators. For these devices the conductor must be wound into robust impregnated coils, which are operated in vacuum at temperatures around 30 K, in strong magnetic fields of about 2T. Differences in thermal contraction between the coil former, conductor constituents, impregnation resin, bandage and heat-sink materials (assembled at room temperature) cause mechanical stresses at operating temperature. Rotating-machine operation adds Lorentz forces and challenging centripetal accelerations up to thousands of g. Second generation-HTS conductors withstand large tensile stresses in axial direction and compression in normal direction. However, shear stresses, axial compression, and tension normal to the conductor can cause degradation in superconducting properties. Such stresses can be mitigated by correct choice of materials, coil lay-out and manufacturing process. A certain stress level will remain, which the conductor must withstand. We have manufactured many impregnated round and race-track coils, using different 2G-HTS conductors, and tested them at temperatures from 25 K to 77 K. Degradation of the superconductor in early coils was traced to the mentioned differences in thermal contraction, and was completely avoided in coils produced later. We will discuss appropriate coil-winding techniques to assure robust and reliable superconductor performance.

    Indole-3-acetic acid (IAA)/diol based pH-sensitive biopolymeric hydrogels with tunable biological properties (cytotoxicity, anti-oxidant and anti-fungal) have been synthesized via condensation polymerization. The present study focused on the synthesis of heterocyclic hydrogel using citric acid (CA), indole-3-acetic acid (IAA) and diethylene glycol (DEG) by condensation polymerization. The hydrogels revealed a pH-sensitive swelling behaviour, with increased swelling in acidic media, then turns to decreased the swelling in the basic media. The hydrogel samples were tested for antifungal activity against Aspergillus fumigates, Rhizopusoryzae and Candida albicans at different concentrations using ketoconazole as positive control and DMSO as negative control for antifungal activity. Antioxidant activity increasing nature in DPPH than NO radical compared with rutin and confirmed non toxic property using cytotoxicity analysis. The biopolymeric hydrogels were characterized by Fourier transform infrared (FT-IR) spectroscopy, 1 H NMR, 13 C NMR, TGA, DSC followed by scanning electron microscopy (SEM). Such hydrogels with antioxidant properties is recommended for medical applications such as bandages, catheters, drains and tubes to prevent infection. Copyright © 2016 Elsevier B.V.

    2004-01-01

    To describe immunolocalization of TGF-beta receptors (RI and RII) in normal equine skin and in thoracic or limb wounds, healing normally or with exuberant granulation tissue (EGT). Group A: six wounds on one metacarpus and one midthoracic area. Group B: six wounds on both metacarpi, one of which was bandaged to stimulate EGT. Immunohistochemistry was used to detect RI and RII expression in wound margins. Eight horses, randomly assigned to one of two study groups. Neutralizing polyclonal anti-rabbit RI and RII antibodies were used to detect spatial expression of RI and RII in biopsies obtained before wounding, at 12 and 24 hours, and 5, 10 and 14 days after wounding. RI and RII were co-localized in both unwounded and wounded skin. There were no differences in cell types staining positively between tissues obtained from the limb and the thorax, or from normally healing limb wounds and limb wounds with EGT, at any time. Because of increased cellularity within EGT, staining intensity of limb wounds with 'proud flesh' was greater than limb wounds healing normally, and thoracic wounds, during the proliferative phase of repair. Strong expression of RI and RII, particularly in limb wounds with EGT, suggested that signalling for stimulation of matrix proteins is in place to contribute to scarring. This information may help determine the appropriate time for using receptor antagonists to prevent scarring of limb wounds of horses.

  2. Wound care in horses.

    Caston, Stephanie S

    2012-04-01

    Care of equine wounds in the field can be a challenging endeavor. Many times, wound care is complicated by chronicity or by prior inappropriate care in addition to the great degree of tissue trauma that occurred when the horse was wounded. Recognizing involvement of synovial structures, loss of skin, and damage to bone are critical in the initial examination of wounds and will guide future care. Education of clients is also important in that preparing them for possible outcomes during healing may help improve compliance and proper treatment of wound. Owners and trainers often perform much of the daily care and monitoring of equine wounds and thus can greatly assist or impede the progress. Bandaging is important to management of equine wounds-especially on the limbs-and is sometimes overlooked because of its labor-intensive nature and the desire for a spray, ointment, or salve that will heal the wound. The practitioner that improves and utilizes his or her understanding of the wound-healing process in concert with his or her knowledge of local anatomy will be the one who is best equipped to care for wounds in ambulatory practice.

    Topical oxygen therapy (TOT) has been used in human medicine to promote healing in chronic wounds. To test the efficacy and safety of TOT in horses, an experimental wound model was created by making 1 standardized dermal wound on each limb of 4 healthy horses (n = 16). Each wound was fitted with an oxygen delivery cannula and covered with a bandage. One limb of each front and hind pair was randomly assigned to the treatment group (fitted with an oxygen concentrator device), with the contralateral limb assigned to the control group (no device). Wound area, epithelial area, and contraction were measured every 3 to 4 d. Biopsy samples and culture swabs were taken on days 16 and 32 to evaluate angiogenesis, fibroplasia, epithelial hyperplasia, inflammation and bacterial growth. Mean healing time in treated wounds (45 d, range: 38 to 52 d) was not significantly different from that in the paired control wounds (50 d, range: 38 to 62 d). Topical oxygen therapy had little effect on dermal wound healing in this experimental wound model in healthy horses. PMID:25477541

    Full Text Available ABSTRACT Objective: to identify the mean direct cost (MDC of the most frequent procedures performed by nursing professionals on severely burned patients in an Intensive Care Unit. Method: exploratory-descriptive quantitative single-case study. The MDC was calculated by multiplying time (timed spent by nursing professionals in the performance of the procedures by the unit cost of direct labor, and adding the costs of material and medicine/solutions. Results: a MDC of US$ 0.65 (SD=0.36 was obtained for "vital signs monitoring"; US$ 10.00 (SD=24.23 for "intravenous drug administration"; US$ 5.90 (SD=2.75 for "measurement of diuresis"; US$ 0.93 (SD=0.42 for "capillary blood glucose monitoring"; and US$ 99.75 (SD=129.55 for "bandaging". Conclusion: the knowledge developed can support managerial decision-making, contribute to the efficiency distribution of the resources involved and, when possible, provide cost-containment or cost-minimization strategies without impairing the quality of nursing care.

    The potential for skin damage from adhesive products is documented in the literature. Nevertheless, health care providers continue to lack understanding of the impact and seriousness of skin injury associated with use of tapes or other adhesive devices when applied to a patient with a history or hypersensitivity or allergy to adhesives. A 67-year-old woman with a history of tape allergy underwent emergency appendectomy. Initial removal of an adhesive bandage placed over the surgical incision revealed medical adhesive-related skin injury (MARSI). The largest of the 3 wounds was a Class III skin tear based on the Payne-Martin Classification System. It measured (L) 4.4 cm × (W) 1.8 cm × (D) 0.3 cm and required 3 months to heal. Experiences with this case revealed the need for evidence-based practice innovations to prevent physical, emotional, and economic cost resulting from MARSI. We recommend early identification and careful documentation of susceptibility to MARSI prior to surgery and implementation of consensus-based recommendations for prevention of MARSI as advocated by the MARSI consensus group when preparing patients for surgery and treating wounds.

    Full Text Available AbstractThe purpose of this study was to assess the effect of ankle external supports on proprioception and dynamic balance in volleyball players. Seventeen female volleyball players (18.94±2.49 years; 65.45±9.49 kg; 1.71±0.05 m; BMI=22.0±2.67 kg/m² took part in this study. The dynamic balance was assessed through the Star Excursion Balance Test (SEBT. Comparisons between stabilization (no stabilizer/NS, orthosis/ORT and functional bandaging/FB modes and the SEBT grid lines and inter-limb were carried out. The SEBT assessment showed a significant difference between the groups NS x ORT and NS x FB (p < .01, and between the lines (p< .01. Significant line/limb interaction in DL and NDL (p< .01 was detected. The external supports tested herein showed similar effects on balance, restricting lower limb's reach in the SEBT execution in some of tested directions.

    Full Text Available In this research, a piezoelectric film was utilized to develop a low-cost biomedical device for diagnosis and management of breathing disorders. First, it was shown that when a commercial polyvinylidene fluoride (PVDF film was subjected to airflow generated from human breath, the voltage generated increased with decreasing film thickness. Then, a device was fabricated that records a patient's breathing pattern and sends this data to a remote email address via the Raspberry Pi, an inexpensive computer. It was shown that the breathing patterns could be recorded in a reproducible manner with this device. Next, the efficacy of the device to detect breathing disorders was tested. A restrictive ventilatory abnormality was simulated by tying a crepe bandage around the chest. It was shown that this device could successfully distinguish between breathing in a normal patient and the breathing of a patient with a restrictive ventilatory abnormality. It is possible to fabricate this device for less than $100, thereby making it accessible to a large number of patients with chronic lung diseases.

    Full Text Available Ovariesalpingohistectomy (OSH is a reproductive cycle inhibitor often used to control canine and feline populations, as well as infectious diseases that spread from these and other animals to humans. In an attempt to make OSH a practical and crucial part of the public health programs, several studies have been developed focusing on minimizing surgical trauma, surgical time and reducing operating costs. The purpose is in examining the effectiveness, practicality and functionality of nylon tie-rap as an alternative method in reducing hemostasis in felines. The nylon tie-rap, originally designed for electro-hydraulic maneuvers, has been tested in some surgical procedures in which securer vascular bandages are required. Results from using nylon tie-rap during feline operations offered effective patient care in less time, reduced scarring and faster recuperation. Fifty healthy adult female felines of varying species, size and weight were referred to the Veterinary Medicine Hospital - UFBA to undergo surgical procedures to measure physiological changes in their reproductive hormones. Based on the results, the nylon tie-rap offered one of the safest medical devices and provided resistance to traction without breakage or loosening during or after application. In conclusion, the nylon tie-rap has far-reaching potential as a vascular bandage, in which it can be surgically inserted easily, reduces clinical cost and increases the number of patients in need of veterinarian care.A ovariosalpingohisterectomia (OSH é indicada para inibição do ciclo estral, frequentemente empregada no controle populacional de cães e gatos e, consequentemente, no controle de zoonoses. Na tentativa de viabilizar esse procedimento, visando sua aplicação em programas de saúde pública, diversos estudos vêm sendo desenvolvidos objetivando minimizar os traumas cirúrgicos, otimizar o tempo de cirurgia e, principalmente, diminuir os custos operacionais.

    Full Text Available This study was performed to investigate the different methods of treating hyper granulation tissue on experimentally induced wounds in equine limbs. Wounds were induced by removal of a skin patch and subcutaneous tissue for about 5-7 cm width and 6-8 cm in length from the dorsal and lateral aspect of the fore and hind limbs below the carpal and tarsal joints. The wounds were left open without treatment and the animals were trained 2-2.5 hours every day for about 3-5 weeks until hyper granulation tissue was developed. The schedule for the treatment of hyper granulation was divided into five groups each contained eight wounds of hyper granulation tissue; each main group was divided into two subgroups. The subgroups of first, second, third, fourth and fifth groups were treated by the following schedules: bandage alone; copper sulphate ointment 10%; silver nitrate ointment 2%; red mercury ointment 11%; and laser therapy (at a total dose of 9.72 Joule / cm2 respectively. While the second subgroups were treated by surgical resection of the hyper granulation tissue, followed by the same treatments applied on the first subgroup. The bandage for all experimental groups was changed every 48 hours until healing was occurred. The clinical and histological observation of the first group revealed that the healing take long period comparing with other groups. The mean of wound healing were 65 days in non surgical removal of hyper granulation tissue subgroup, while 57 days in surgical removed of hyper granulation tissue subgroup. The results of the second, third, fourth groups revealed that the caustic material especially red mercury has a role in healing processes through depressing the hyper granulation tissue. The mean of wound healing of the second group was 42.25 days in non surgical removal of hyper granulation tissue subgroup while 37.25 days in surgically removed hyper granulation tissue subgroup. In the third group the mean of wound healing was 45

    Nail tic disorders are classic examples of overlap between the domains of dermatology and psychiatry. They are examples of body-focused repetitive behaviors in which there is an irresistible urge or impulse to perform a certain behavior. The behavior is reinforced as it results in some degree of relief and pleasure. Nail tic disorders are common, yet poorly studied and understood. The literature on nail tic disorders is relatively scarce. Common nail tics include nail biting or onychophagia, onychotillomania and the habit tic deformity. Some uncommon and rare nail tic disorders are onychoteiromania, onychotemnomania, onychodaknomania and bidet nails. Onychophagia is chronic nail biting behavior which usually starts during childhood. It is often regarded as a tension reducing measure. Onychotillomania is recurrent picking and manicuring of the fingernails and/or toenails. In severe cases, it may lead to onychoatrophy due to irreversible scarring of the nail matrix. Very often, they occur in psychologically normal children but may sometimes be associated with anxiety. In severe cases, onychotillomania may be an expression of obsessive-compulsive disorders. Management of nail tic disorders is challenging. Frequent applications of distasteful topical preparations on the nail and periungual skin can discourage patients from biting and chewing their fingernails. Habit-tic deformity can be helped by bandaging the digit daily with permeable adhesive tape. Fluoxetine in high doses can be helpful in interrupting these compulsive disorders in adults. For a complete diagnosis and accurate management, it is imperative to assess the patient's mental health and simultaneously treat the underlying psychiatric comorbidity, if any.

  11. Decontamination of injured persons in the hospital in case of NBC hazards

    Prompt recognition of contaminated people is a prerequisite for the activation of a decontamination plan. Because simple detection methods are missing, the clinical awareness for such events has to be raised. The objectives of such a plan are protection of the hospital and its staff due to secondary contamination, the rapid termination of the exposure of casualties and their treatment, if necessary. The response plan should account for exposed individuals whose contamination has been noticed in the emergency department (contaminated E.D.) as well as for the announced influx of such persons. The implementation of such a plan and its elements are not necessarily expensive and decontamination can be realized with a few employees. Personal protective equipment (PPE) is indispensable and frequent exercises are necessary to keep its protective effect. Donning and doffing PPE should be easy and personnel in different physical conditions should be able to wear it. Waterproof, chemical-resistant suits, full-face masks and powered air purifying respirators with particle filters and absorbent cartridges are necessary. Decontamination consists of undressing clothes, showers with warm water and cleaning the skin with soap. Abrasions may be cleaned in the same way whereas complex wounds should be irrigated with sterile isotonic solution and dressed with waterproof adhesive bandage before showering. Presumably, waste water may be drained into sewer system without endangering people or environment. Mutual agreements between hospitals and water authorities are recommended. To achieve the concept described, a group of interested, knowledgeable employees should compile all details specifically for their hospital. Suggestions and ideas how to realize this goal are given in this report. Good cooperation of all participants in the chain of treatment may reduce the risk for affected people, but these links between hospitals, emergency medical services, fire services and police

  12. Migrating Huns and modified heads: Eigenshape analysis comparing intentionally modified crania from Hungary and Georgia in the Migration Period of Europe.

    Directory of Open Access Journals (Sweden)

    Peter Mayall

    Full Text Available An intentionally modified head is a visually distinctive sign of group identity. In the Migration Period of Europe (4th- 7th century AD the practice of intentional cranial modification was common among several nomadic groups, but was strongly associated with the Huns from the Carpathian Basin in Hungary, where modified crania are abundant in archaeological sites. The frequency of modified crania increased substantially in the Mtskheta region of Georgia in this time period, but there are no records that Huns settled here. We compare the Migration Period modified skulls from Georgia with those from Hungary to test the hypothesis that the Huns were responsible for cranial modification in Georgia. We use extended eigenshape analysis to quantify cranial outlines, enabling a discriminant analysis to assess group separation and identify morphological differences. Twenty-one intentionally modified skulls from Georgia are compared with sixteen from Hungary, using nineteen unmodified crania from a modern population as a comparative baseline. Results indicate that modified crania can be differentiated from modern unmodified crania with 100% accuracy. The Hungarian and Georgian crania show some overlap in shape, but can be classified with 81% accuracy. Shape gradations along the main eigenvectors indicate that the Hungarian crania show little variation in cranial shape, in accordance with a two-bandage binding technique, whereas the Georgian crania had a wider range of variation, fitting with a diversity of binding styles. As modification style is a strong signifier of social identity, our results indicate weak Hunnic influence on cranial modification in Georgia and are equivocal about the presence of Huns in Georgia. We suggest instead that other nomadic groups such as Alans and Sarmatians living in this region were responsible for modified crania in Georgia.

E-mail: georgia_goss@hotmail.com The carpal hygroma is characterized by an abnormal fluid accumulation in a dorsal surface of this region, that is presented with soft consistency, painless and doesn’t lead to lameness. The main cause of hygroma is a constant local trauma. This is a commom disease in horses who live in hard surface sites and, it can also affect ruminants. The diagnosis is achieved by clinical signs and additional tests such as cytological analysis, radiographic and sonographic. The early diagnosis is important because the therapeutic options vary with the degree of evolution of the disease. The treatment may vary from hygroma drainage, with or without application of corticosteroids, followed by compressive bandages to the surgical ablation of this. The objective of this case report is to account the occurrence of a carpal hygroma in sheep. This report is important because the sheeps are being widely created in intensive systems and diseases like hygroma are becoming common, because this is a fundamental supply subsidy to the clinicians, in the literature, to assist in their daily routine.

    The question whether or not a patient with a hip brace should drive a car is of obvious importance because the advice given to patients to resume driving is often anecdotal as few scientific data are available on this specific subject. To assess driving ability (brake response time) with commonly used hip braces. Repeated measures design. Brake response time was assessed under six conditions: (1) without a brace (control), (2) with a typical postoperative hip brace with adjustable range of motion and the settings: unrestricted, (3) flexion limited to 70°, (4) extension blocked at 20° hip flexion, (5) both flexion and extension limited (20°/70°) and (6) an elastic hip bandage. Brake response time was assessed using a custom-made driving simulator as used in previous studies. The participants were a convenience sample of able-bodied participants. A total of 70 participants (35 women and 35 men) participated in our study. Mean age was 31.1 (standard deviation: 10.6; range: 21.7-66.4) years. A significant within-subject effect for brake response time was found ( p = 0.009), but subsequent post hoc analyses revealed no significant differences between control and the other settings. Based on our findings, it does not seem mandatory to recommend driving abstinence for patients wearing a hip orthosis. We suggest that our results be interpreted with caution, because (1) an underlying pathological hip condition needs to be considered, (2) the ability to drive a car safely is multifactorial and brake response time is only one component thereof and (3) brake response time measurements were performed only with healthy participants. Clinical relevance Hip braces are used in the context of joint-preserving and prosthetic surgery of the hip. Therefore, clinicians are confronted with the question whether to allow driving a car with the respective hip brace or not. Our data suggest that hip braces do not impair brake response time.

    Full Text Available A 28-year-old presented with complaints of severe pain and redness in the left eye since 2 weeks. He had similar complaints in the right eye 2 years back for which he had undergone a scleral patch graft. Best corrected visual acuity was 20/20 in both eyes. The right had a well vascularized scleral graft and rest of the anterior segment was normal. The left eye had inferior conjunctival congestion with an area of the scleral melt with uveal show just temporal to the limbus in the interpalbebral area. The cornea was clear and anterior chamber was quiet in the left eye. Applanation tonometry and fundus evaluation were normal in both eyes. Physical examination revealed hyperpigmented skin lesion, hypertrichosis and absorption of distal phalanges. Laboratory, ocular and physical findings confirmed the diagnosis of congenital erythropoietic porphyria. He was on oral steroids 40 mg/day since 2 weeks and topical antibiotics and lubricants. He was advised to continue the same and was taken up for scleral patch graft with fibrin glue in the left eye. Postoperatively he was continued on topical and oral steroids and lubricants.3 weeks later the left eye had stabilized however patient came with a melt in the right eye. Since it was an early melt, we went ahead with cyanoacrylate glue and bandage contact lens in the right eye and started him on topical steroids for the right eye also. Three months later both the eyes were stable, and the patient was gradually tapered off the steroids.

    The perceived and reported pain of patients receiving photorefractive keratectomy (PRK) widely varies. We assessed the potential role of the subbasal nerve plexus density as a predictor of postoperative pain level. Consecutive patients scheduled to undergo PRK at the Refractive Surgery Clinic of Farabi Eye Hospital, Tehran, were approached. Forty-nine myopic left eyes from 49 patients who consented to undergo scanning slit confocal microscopy assessments preoperatively were included. ImageJ (1.48v) was used to measure the captured subbasal nerve length. Postoperative pain intensity was assessed by the Visual Analog Scale (VAS) (score range: 0 for no pain to 10 for the maximum possible) on the next day of surgery. The mean age of the patients was 27.55 (range: 19-40) years. The median reported pain level was 5. Approximately 32.7% of the subjects reported a pain score of 6 or higher. Mean nerve density was 19.54 (range: 14.34-24.73) mm/mm 2 . Nerve density was not correlated with the reported intensity of pain ( P = 0.172). However, pain was correlated with the reported ocular discomfort, i.e., a pooled index of foreign body sensation, photophobia, burning sensation, and tearing ( P < 0.001), and also with the pooled index of ocular inflammatory signs (conjunctival injection and eyelid edema) ( P = 0.027). Crude density of corneal nerves may not be a good predictor of post-PRK pain while wearing bandage contact lenses. The predominant pain mechanism appears to be of an inflammatory nature (not nociceptive or neuropathic).

    Full Text Available Inherited epidermolysis bullosa (EB is a heterogeneous group of genetic disorders that present with skin and, in some cases, mucosal fragility, predisposing patients to the development of blisters and/or erosions after minimal trauma or friction. Children with a recurrent history of these kinds of lesions or neonates that present them in the absence of another reasonable explanation should be investigated. Diagnosis must be based on clinical and histopathological findings. To date, management of inherited EB basically consists in avoiding traumas that trigger lesions, as well as preventing infection and facilitating healing of the wounds with the systematic use of bandages.A epidermólise bolhosa hereditária (EBH compreende um grupo heterogêneo de desordens genéticas que têm em comum a fragilidade cutânea e, em alguns casos mucosa, predispondo ao desenvolvimento de bolhas e/ou erosões após fricção ou trauma mínimo. Crianças com história recorrente deste tipo de lesão ou neonatos que as apresentem na ausência de outra explicação plausível devem ser investigados. O diagnóstico deve se basear em achados clínicos e histopatológicos. Até o presente momento, o manejo da EBH consiste basicamente em evitar os traumas desencadeadores das lesões, bem como evitar a infecção e facilitar a cicatrização das feridas com o uso sistemático de curativos.

    Leg ulcers usually occur secondary to venous reflux or obstruction, but 20% of people with leg ulcers have arterial disease, with or without venous disorders. Between 1.5 and 3.0 in 1000 people have active leg ulcers. Prevalence increases with age to about 20 in 1000 people aged over 80 years. We conducted a systematic overview, aiming to answer the following clinical questions: What are the effects of treatments for venous leg ulcers? What are the effects of organisational interventions for venous leg ulcers? What are the effects of advice about self-help interventions in people receiving usual care for venous leg ulcers? What are the effects of interventions to prevent recurrence of venous leg ulcers? We searched: Medline, Embase, The Cochrane Library, and other important databases up to March 2014 (Clinical Evidence overviews are updated periodically; please check our website for the most up-to-date version of this overview). At this update, searching of electronic databases retrieved 116 studies. After deduplication and removal of conference abstracts, 63 records were screened for inclusion in the overview. Appraisal of titles and abstracts led to the exclusion of 43 studies and the further review of 20 full publications. Of the 20 full articles evaluated, four systematic reviews were updated and four RCTs were added at this update. We performed a GRADE evaluation for 23 PICO combinations. In this systematic overview, we categorised the efficacy for 13 interventions based on information about the effectiveness and safety of advice to elevate leg, advice to keep leg active, compression stockings for prevention of recurrence, compression bandages and stockings to treat venous leg ulcers, laser treatment (low level), leg ulcer clinics, pentoxifylline, skin grafting, superficial vein surgery for prevention of recurrence, superficial vein surgery to treat venous leg ulcers, therapeutic ultrasound, and topical negative pressure.

    Hand and foot burns in children are difficult to dress. The authors have developed a soft casting technique to manage burns to these areas. The aim of this study is to report the outcomes using weekly dressing changes with a soft casting technique to manage pediatric hand and foot burns in the outpatient setting. A retrospective chart review was performed on children with burns to the hands or feet, who underwent dressing changes with a soft casting technique at the Children's Hospital Colorado Burn Center. Soft casting was performed by placing antibiotic ointment-impregnated nonadherent gauze over the burn wound(s), wrapping the extremity using rolled gauze, applying soft cast pad, plaster, soft cast tape, and an elastic bandage. This was changed weekly. Two hundred ninety-eight children with hand burns had a mean age of 16.8 ± 2 months. Two hundred forty-eight children had partial thickness burn injuries (83%), 50 had full thickness burn injuries (17%), and the mean total body surface area (TBSA) was 1 ± 2.4%. The mean time to heal was 10.1 ± 1.7 days for all subjects. Sixty-six children with foot burns were identified with a mean age of 24 ± 2.6 months. Forty-six children had partial thickness injuries (70%), 20 had full thickness burn injuries (30%), and the mean TBSA was 2.3 ± 2.9%. The mean time to heal was 14.1 ± 2.2 days for all subjects. Weekly dressing changes using a soft casting technique are effective for the outpatient management of pediatric hand and foot burns. This method avoids costly inpatient hospital care, reduces the number of painful dressing changes, and allows children to heal in their own environment.

    Purpose The objective of this pilot study was to investigate if an active bone conduction implant (BCI) used in an ongoing clinical study withstands magnetic resonance imaging (MRI) of 1.5 Tesla. In particular, the MRI effects on maximum power output (MPO), total harmonic distortion (THD), and demagnetization were investigated. Implant activation and image artifacts were also evaluated. Methods and materials One implant was placed on the head of a test person at the position corresponding to the normal position of an implanted BCI and applied with a static pressure using a bandage and scanned in a 1.5 Tesla MRI camera. Scanning was performed both with and without the implant, in three orthogonal planes, and for one spin-echo and one gradient-echo pulse sequence. Implant functionality was verified in-between the scans using an audio processor programmed to generate a sequence of tones when attached to the implant. Objective verification was also carried out by measuring MPO and THD on a skull simulator as well as retention force, before and after MRI. Results It was found that the exposure of 1.5 Tesla MRI only had a minor effect on the MPO, ie, it decreased over all frequencies with an average of 1.1±2.1 dB. The THD remained unchanged above 300 Hz and was increased only at lower frequencies. The retention magnet was demagnetized by 5%. The maximum image artifacts reached a distance of 9 and 10 cm from the implant in the coronal plane for the spin-echo and the gradient-echo sequence, respectively. The test person reported no MRI induced sound from the implant. Conclusion This pilot study indicates that the present BCI may withstand 1.5 Tesla MRI with only minor effects on its performance. No MRI induced sound was reported, but the head image was highly distorted near the implant. PMID:26604836

Treatment response is characterized by periodic remission rather than complete recovery. Compression methods currently used as part of complete decongestive therapy vary considerably in efficacy. Manual drainage, bandaging, and compression pumps are ineffective in everyday practice. Positive results have increasingly been reported where compression garments have been used as part of the treatment. This pilot study demonstrates a beneficial effect following the use of compression corsets in the treatment of edema in breast cancer-related lymphedema (BCRL. Material: A total of 35 women with BCRL were enrolled. Of these, 29 patients completed the study. Methods: Ultrasound (B-mode was used to evaluate lymphedema in the side of the chest after mastectomy. This test was performed three times at a specific site on the operated side and symmetrically on the opposite side. Subsequently, patients were fit with an appropriate compression corset. The data were then statistically analyzed. Conclusion: After the surgical treatment of breast cancer, lymphatic fluid reservoirs may form at the side of the chest. The use of carefully selected compression corsets is an effective treatment for BCRL. Corsets are an important item, which we recommend should be included in compression clothing sets. We anticipate this finding will form the foundation for further work on the use of modern compression garments for the treatment of BCRL as well as contribute to the limited number of published reports that exist on the subject.

    James Hill (1703-1776) was a surgeon from Dumfries in Scotland who can lay claim to being the first to treat head injury patients in a thoroughly modern manner. He was highly regarded in his lifetime and for a century afterwards but has subsequently been forgotten. He had the lowest surgical mortality for trepanation of any surgeon of his time. He uniquely presented his results after a lengthy follow-up of many years. His management of cranial fractures was advanced. He did not use the trepan for fissures as others did and his conservative management of depressed fractures was based on biological rather than mechanical notions. He had an instinct for the management of raised intracranial pressure (ICP) unique in his day even though he could not have understood it in modern terms. He operated on head injuries only if there was a disturbance of consciousness. He was aware of the importance of cerebral pulsation and was alone in recording it in a majority of operated patients. He was ready to open the dura when necessary and did so six times. He introduced non-compressive bandaging over skull defects after surgery. In three cases he shaved off brain hernias which resulted in marked clinical improvement. He not only understood that an injury or disease on one side caused a deficit on the other side but uniquely encompassed this knowledge in his treatment planning. In view of these many insights and achievements, he deserves to be considered as the first surgeon whose neurosurgical management is recognisably close to modern practice.

    Full Text Available Nail tic disorders are classic examples of overlap between the domains of dermatology and psychiatry. They are examples of body-focused repetitive behaviors in which there is an irresistible urge or impulse to perform a certain behavior. The behavior is reinforced as it results in some degree of relief and pleasure. Nail tic disorders are common, yet poorly studied and understood. The literature on nail tic disorders is relatively scarce. Common nail tics include nail biting or onychophagia, onychotillomania and the habit tic deformity. Some uncommon and rare nail tic disorders are onychoteiromania, onychotemnomania, onychodaknomania and bidet nails. Onychophagia is chronic nail biting behavior which usually starts during childhood. It is often regarded as a tension reducing measure. Onychotillomania is recurrent picking and manicuring of the fingernails and/or toenails. In severe cases, it may lead to onychoatrophy due to irreversible scarring of the nail matrix. Very often, they occur in psychologically normal children but may sometimes be associated with anxiety. In severe cases, onychotillomania may be an expression of obsessive-compulsive disorders. Management of nail tic disorders is challenging. Frequent applications of distasteful topical preparations on the nail and periungual skin can discourage patients from biting and chewing their fingernails. Habit-tic deformity can be helped by bandaging the digit daily with permeable adhesive tape. Fluoxetine in high doses can be helpful in interrupting these compulsive disorders in adults. For a complete diagnosis and accurate management, it is imperative to assess the patient's mental health and simultaneously treat the underlying psychiatric comorbidity, if any.

    Purpose: Phantom surrogates were developed to allow multimodal [computed tomography (CT), magnetic resonance imaging (MRI), and teletherapy] and anthropomorphic tissue simulation as well as materials and methods to construct deformable organ shapes and anthropomorphic bone models. Methods: Agarose gels of variable concentrations and loadings were investigated to simulate various soft tissue types. Oils, fats, and Vaseline were investigated as surrogates for adipose tissue and bone marrow. Anthropomorphic shapes of bone and organs were realized using 3D-printing techniques based on segmentations of patient CT-scans. All materials were characterized in dual energy CT and MRI to adapt CT numbers, electron density, effective atomic number, as well as T1- and T2-relaxation times to patient and literature values. Results: Soft tissue simulation could be achieved with agarose gels in combination with a gadolinium-based contrast agent and NaF to simulate muscle, prostate, and tumor tissues. Vegetable oils were shown to be a good representation for adipose tissue in all modalities. Inner bone was realized using a mixture of Vaseline and K 2 HPO 4 , resulting in both a fatty bone marrow signal in MRI and inhomogeneous areas of low and high attenuation in CT. The high attenuation of outer bone was additionally adapted by applying gypsum bandages to the 3D-printed hollow bone case with values up to 1200 HU. Deformable hollow organs were manufactured using silicone. Signal loss in the MR images based on the conductivity of the gels needs to be further investigated. Conclusions: The presented surrogates and techniques allow the customized construction of multimodality, anthropomorphic, and deformable phantoms as exemplarily shown for a pelvic phantom, which is intended to study adaptive treatment scenarios in MR-guided radiation therapy

    2014-09-01

    Full Text Available The polymer compositions on the base of acrylic derivatives and bentonite particles modified by silver ions with various share and dispersion are received and studied by radical polymerization in the water. Partially neutralized acrylic acid, acrylamide and methylene-bis-acrilamide and particles of bentonite with fraction 0 - 0,05 mass.% are chosen as initial substances. The influence of bentonite concentration on absorbing characteristics of polymer materials in the distilled water is shown. It is demonstrated that the increase of bentonite fraction up to 5 mass.% leads to the rise of degree of equilibrium swelling by 1,5 – 2 times in comparison with an unfilled polymer matrix. The acrylic nanocompositions with a mass fraction of bentonite equal to 0,01 mass.% possess the greatest kinetic characteristics. Kinetic dependences of new composite materials swelling in physiological solution from a filler dispersion part are investigated. It is shown that in high dispersion (with particle size less than 0,25 mm a part of mineral–containing filler equal to 1 mass.% leads to significant increase in values of equilibrium swelling degree in comparison with an unfilled sample (by 1,5 times. The effect of polyelectrolyte suppression of polymer composition swelling in physiological solution is studied. It results in values reduction of equilibrium swelling degree in comparison with these values in the distilled water. Application prospects for the received compositions are shown at bandages creation for wounds treatment of various etiologies. Research results are recommended for usage in medical practice for optimization of wound process march.

    During CBR incidents with releases of hazardous materials (HazMat), there is extremely urgent aim of first rescuing responders to safe the life for as much as possible victims and reducing health consequences from the exposure of the HazMat. Highest priority of the response is to be applied, if victims are exposed with chemicals through their airways and/or mucous membranes. There is general approach in the emergency medical services (EMS) stated that the victims being in critical status have to receive emergency medical care on-site even prior the transportation to a medical facility. However, in a case of CBR events the EMS prefer to provide the First Aid for victims to be already decontaminated as mass casualties, e.g. by the firemen and transferred to a safe zone. This approach is to be time consuming and thus creating delays in medical care not in the favor of a victim's successful survival. In order to overcome this approach, there are needs for eminent ceasing of the victims exposure, protection of breathing tract/ventilation support and administration of antidotes, if available. All this have to be done in shortest time since HazMat incident/accident occurs. This presentation is focusing on emergency provisions for saving victims directly in contaminated environment through the assistance by responders, concentrating on search and rescue of victims, their emergency decontamination, breathing protection, clothing removal, ventilation support, antidote administration, fixing and bandage of trauma injuries prior transportation and/or mass decontamination. This experience is shared based on a field exercise with the EMS volunteers (Red Cross), fire brigade volunteers and university's students.(author)

    A 34-y-old man presented to Naivasha District Hospital (NDH) in Naivasha Town, Kenya, with near-complete below-knee amputation and hemorrhage after a hippopotamus attack. Residents from the University of Washington (UW), Departments of Surgery, Anesthesia, and Medicine, were rotating at NDH with the Clinical Education Partnership Initiative, a joint venture of UW and University of Nairobi. These providers met the patient in the operating theater. The leg was mangled with severely traumatized soft tissues and tibia-fibula fractures. The visiting UW Surgery resident (R3) and an NDH medical officer (second-year house officer) performed emergency below-knee completion amputation--the first time either had performed this operation. The three major vessel groups were identified and ligated. Sufficient gastrocnemius and soleus were preserved for future stump construction. The wound was washed out, packed with betadine-soaked gauze, and wrapped in an elasticized bandage. Broad-spectrum antibiotics were initiated. Unfortunately, the patient suffered infection and was revised above the knee. After a prolonged course, the patient recovered well and was discharged home. NDH house officers and UW trainees collaborated successfully in an emergency and conducted the postoperative care of a patient with a serious and challenging injury. Their experience highlights the importance of preparedness, command of surgical basics, humility, learning from mistakes, the expertise of others, a digitally connected surgical community, and the role of surgery in global health. These lessons will be increasingly pertinent as surgical training programs create opportunities for their residents to work in developing countries; many of these lessons are equally applicable to surgical practice in the developed world.

    The aim of the study was to investigate the impact of stress, illness perceptions, and behaviors on healing of venous leg ulcers. A prospective observational study of 63 individuals for 24 weeks investigated possible psychosocial predictors of healing. There were two indices of healing: rate of change in ulcer area and number of weeks to heal. Psychological variables were assessed at baseline using self-report measures (Perceived Stress Scale, Hospital Anxiety and Depression Scale, Revised Illness Perception Questionnaire, adapted Summary of Diabetes Self-Care Activities, Adherence Questionnaire, and Short-Form Health Survey). Controlling for sociodemographic and clinical variables, for the 24 weeks, a slower rate of change in ulcer area was predicted by greater stress (standardized β = -0.61, p = .008), depression (standardized β = -0.51, p = .039), and holding negative perceptions or beliefs about the ulcer (standardized β = -1.4, p = .045). By 24 weeks, 69% of ulcers had closed. A more negative emotional response to the ulcer at baseline (i.e., emotional representation of the ulcer) was associated with a greater number of weeks to heal (hazard ratio [HR] = 0.63, 95% confidence interval [CI] = 0.41-0.95, p = .028). Higher educational attainment (HR = 3.22, 95% CI = 1.37-7.55, p = .007) and better adherence to compression bandaging (HR = 1.41, 95% CI = 1.06-1.88, p = .019) were associated with fewer weeks to heal. No other psychosocial variable (stress, perceptions about the ulcer, health behaviors) predicted weeks to heal. Alongside ulcer-related predictors, psychological and sociodemographic factors were associated with healing. Future research should explore mediating mechanisms underlying these associations and develop interventions to target these variables.

    Full Text Available OSCEs (Objective Structured Clinical Examinations are widely used in health professions to assess clinical skills competence. Raters use standardized binary checklists (CL or multi-dimensional global rating scales (GRS to score candidates performing specific tasks. This study assessed the reliability of CL and GRS scores in the assessment of veterinary students, and is the first study to demonstrate the reliability of GRS within veterinary medical education. Twelve raters from two different schools (6 from University of Calgary [UCVM] and 6 from Royal (Dick School of Veterinary Studies [R(DSVS] were asked to score 12 students (6 from each school. All raters assessed all students (video recordings during 4 OSCE stations (bovine haltering, gowning and gloving, equine bandaging and skin suturing. Raters scored students using a CL, followed by the GRS. Novice raters (6 R(DSVS were assessed independently of expert raters (6 UCVM. Generalizability theory (G theory, analysis of variance (ANOVA and t-tests were used to determine the reliability of rater scores, assess any between school differences (by student, by rater, and determine if there were differences between CL and GRS scores. There was no significant difference in rater performance with use of the CL or the GRS. Scores from the CL were significantly higher than scores from the GRS. The reliability of checklist scores were .42 and .76 for novice and expert raters respectively. The reliability of the global rating scale scores were .7 and .86 for novice and expert raters respectively. A decision study (D-study showed that once trained using CL, GRS could be utilized to reliably score clinical skills in veterinary medicine with both novice and experienced raters.

    Objective—To investigate the ability of medical and nursing staff to perform certain tasks while wearing a chemical protection suit with a respirator. Tasks chosen were those that would be required before decontamination. Methods—Ten experienced accident and emergency doctors (middle grade and consultants) and 10 nurses were asked to perform certain tasks that were judged to be life saving, relevant to triage, or necessary to confirm death, on an advanced life support manikin, while wearing a TST-Sweden chemical protection suit. The operators were objectively assessed by one of the authors for achieving each task, then asked to make a subjective assessment of the difficulty experienced. Results—Medical staff were asked to ventilate the manikin using a bag-valve-mask, intubate within 30 seconds, apply monitor electrodes and cables and check cardiac rhythm, apply gel pads and defibrillate safely, and finally, fold the cruciform triage card to show "RED", and attach it to the manikin. All the doctors completed these tasks, except for one, who could only intubate the manikin after several attempts. Nursing staff were asked to open and apply an oxygen mask, adjust oxygen flow, size and insert an oropharyngeal airway, ventilate the manikin using a bag-valve-mask, apply a pressure bandage to a limb, and fold the cruciform triage card to show "YELLOW", and attach it to the manikin. All the nurses completed these tasks. Operators reported varying degrees of difficulty, the most difficult tasks were those requiring fine movements or delicate control. Generally, operators found the butyl rubber gloves cumbersome. Communication difficulties were frequently reported. Although only intubation was formally timed, tasks were perceived to take longer. Some operators found the suits too warm and uncomfortable. Conclusion—Should the need arise, the TST-Sweden chemical protection suits would enable experienced doctors and nurses to perform lifesaving measures effectively

    An intentionally modified head is a visually distinctive sign of group identity. In the Migration Period of Europe (4th– 7th century AD) the practice of intentional cranial modification was common among several nomadic groups, but was strongly associated with the Huns from the Carpathian Basin in Hungary, where modified crania are abundant in archaeological sites. The frequency of modified crania increased substantially in the Mtskheta region of Georgia in this time period, but there are no records that Huns settled here. We compare the Migration Period modified skulls from Georgia with those from Hungary to test the hypothesis that the Huns were responsible for cranial modification in Georgia. We use extended eigenshape analysis to quantify cranial outlines, enabling a discriminant analysis to assess group separation and identify morphological differences. Twenty-one intentionally modified skulls from Georgia are compared with sixteen from Hungary, using nineteen unmodified crania from a modern population as a comparative baseline. Results indicate that modified crania can be differentiated from modern unmodified crania with 100% accuracy. The Hungarian and Georgian crania show some overlap in shape, but can be classified with 81% accuracy. Shape gradations along the main eigenvectors indicate that the Hungarian crania show little variation in cranial shape, in accordance with a two-bandage binding technique, whereas the Georgian crania had a wider range of variation, fitting with a diversity of binding styles. As modification style is a strong signifier of social identity, our results indicate weak Hunnic influence on cranial modification in Georgia and are equivocal about the presence of Huns in Georgia. We suggest instead that other nomadic groups such as Alans and Sarmatians living in this region were responsible for modified crania in Georgia. PMID:28152046

    Though road traffic injuries (RTIs) are a major cause of mortality in East Africa, few countries have emergency medical services. The aim was to create a sustainable and efficient prehospital lay first responder program, creating a system with lay first responders spread through the 53 motorcycle taxi stages of Iganga Municipality. One hundred and fifty-four motorcycle taxi riders were taught a first aid curriculum in partnership with a local Red Cross first aid trainer and provided with a first aid kit following WHO guidelines for basic first aid. Pre- and post-survey tests measured first aid knowledge improvement over the course. Post-implementation incident report forms were collected from lay first responders after each patient encounter over 6 months. Follow-up interviews were conducted with 110 of 154 trainees, 9 months post-training. Improvement was measured across all five major first aid categories: bleeding control (56.9 vs. 79.7%), scene management (37.6 vs. 59.5%), airway and breathing (43.4 vs. 51.6%), recovery position (13.1 vs. 43.4%), and victim transport (88.2 vs. 94.3%). From the incident report findings, first responders treated 250 victims (82.8% RTI related) and encountered 24 deaths (9.6% of victims). Of the first aid skills, bleeding control and bandaging was used most often (55.2% of encounters). Lay first responders provided transport in 48.3% of encounters. Of 110 lay first responders surveyed, 70 of 76 who had used at least one skill felt "confident" in the care they provided. A prehospital care system composed of lay first responders can be developed leveraging existing transport organizations, offering a scalable alternative for LMICs, demonstrating usefulness in practice and measurable educational improvements in trauma skills for non-clinical lay responders.

    Introduction Nanocapsules, existing in miniscule size, range from 10 nm to 1000 nm. They consist of a liquid/solid core in which the drug is placed into a cavity, which is surrounded by a distinctive polymer membrane made up of natural or synthetic polymers. They have attracted great interest, because of the protective coating, which are usually pyrophoric and easily oxidized and delay the release of active ingredients. Methods Various technical approaches are utilized for obtaining the nanocapsules; however, the methods of interfacial polymerization for monomer and the nano-deposition for preformed polymer are chiefly preferred. Most important characteristics in their preparation is particle size and size distribution which can be evaluated by using various techniques like X-ray diffraction, scanning electron microscopy, transmission electron microscopy, high-resolu¬tion transmission electron microscopy, X-ray photoelectron spectroscopy, superconducting quantum interference device, multi angle laser light scattering and other spectroscopic techniques. Results Nanocapsules possessing extremely high reproducibility have a broad range of life science applications. They may be applied in agrochemicals, genetic engineering, cosmetics, cleansing products, wastewater treatments, adhesive component applications, strategic delivery of the drug in tumors, nanocapsule bandages to fight infec¬tion, in radiotherapy and as liposomal nanocapsules in food science and agriculture. In addition, they can act as self-healing materials. Conclusion The enhanced delivery of bio¬active molecules through the targeted delivery by means of a nanocapsule opens numerous challenges and opportunities for the research and future development of novel improved therapies.

    Full Text Available Background: Wound healing is a complex biological process. Some injuries lead to chronic nonhealing ulcers, and healing process is a challenge to both the patient and the medical team. We still look forward an appropriate wound dressing. Materials and Methods: In this study, starch-based nanocomposite hydrogel scaffolds reinforced by zeolite nanoparticles (nZ were prepared for wound dressing. In addition, a herbal drug (chamomile extract was added into the matrix to accelerate healing process. To estimate the cytocompatibility of hydrogel dressings, fibroblast mouse cells (L929 were cultured on scaffolds. Then, 3-(4, 5-dimethylthiazol-2-yl-2, 5-diphenyltetrazolium-bromide assay test and interaction of cells and scaffolds were evaluated. For evaluating healing process, 48 male rats were randomly divided into four groups of four animals each (16 rats at each step. The ulcers of the first group were treated with the same size of pure hydrogels. The second group received a bandage with the same size of hydrogel/extract/4 wt% nZ (hydrogel NZE. The third group was treated with chamomile extract, and the fourth group was considered as control without taking any medicament. Finally, the dressings were applied on the chronic refractory ulcers of five patients. Results: After successful surface morphology and cytocompatibility tests, the animal study was carried out. There was a significant difference between starch/extract/4 wt% nZ and other groups on wound size decrement after day 7 (P < 0.05. At the clinical pilot study step, the refractory ulcers of all five patients were healed without any hypersensitivity reaction. Conclusion: Starch-based hydrogel/zeolite dressings may be safe and effective for chronic refractory ulcers.

    Byzantine physicians (4th-7th and 8th-12th centuries A.D.), especially those interested in Surgery, developed a number of interesting concepts, views and opinions referring to the field now recognized as Oral and Cranio-maxillofacial Surgery and Pathology. The original texts of Byzantine physicians, written in ancient Greek, and now preserved in the electronic platform Thesaurus Linguae Graecae, at the University of California, Irvine, CA, USA, were investigated in relation to Oral and Cranio-maxillofacial Surgery and Pathology. The most eminent physicians of the Early (4th-7th century A.D.) and Middle (8th-12th century A.D.) Byzantine Period, in particular Oribasius Pergamenus, Aëtius Amidenus, Alexander Trallianus, Theophilus Protospatharius, Paulus Aegineta, Meletius Monachos, and Leo Medicus, in their works deal with topographic and surgical anatomy of the head and neck, and a large list of related topics, including dentoalveolar surgery, oral and cervicofacial infections, trauma of viscerocranium and neurocranium as well as the biomechanics of traumatic brain injuries, temporomandibular joints dysfunction as a consequence of mandibular dislocation, surgical oncology and reconstructive surgery of the head and neck, oral pathology, surgical pathology of salivary glands, therapeutic management of facial nerve dysfunction, preprosthetic surgery, craniofacial surgery, and deformities of the facial skeleton involving anthropologic and craniometric observations. Clinical examination of patients presenting corresponding functional and esthetic problems is considered, using recognizable orthodontic and orthognathic surgical approaches. Finally, specific bandages of the head and neck are described, for treating traumatic injuries of the viscerocranium and neurocranium, diastasis of the cranial sutures, dislocations of the mandible (unilateral and bilateral), as well as inflammatory diseases of the parotids and the neck.

    2012-09-01

    Since the effectiveness of antibiotic treatment is decreasing due to the development of resistant strains, alternative approaches for destroying microorganisms are needed. In this review we summarize new technologies that might be effective for pathogen inactivation. In the past we found that intense blue light could be used for bacterial eradication. The phototoxic effect correlated with the amount of reactive oxygen species (ROS) generated by the bacteria due to illumination. Recently it has been shown that the effect of light can be enhanced by introducing metal oxide nanoparticles (nps) to the bacteria prior to irradiation. This led us to suggest combining nanoparticles with visible light irradiation for pathogen eradication. We have shown that combination of illumination with the nanoparticles (ZnO or TiO2) resulted in a marked increase in the reduction of bacterial viability to a mean reduction of 80-90% for both nanoaprticles. As a matter of fact metal oxide nps alone can be used for bacteria destruction. The advantage of our approach is the use of lower concentrations of nps, combined with reduced light intensity that is less toxic to the host tissue. To further avoid the toxicity of metal oxides nps on healthy tissue it is possible to coat their surfaces with various substrates including ceramics and polymers. Recently Zinc oxide nanoparticles have been synthesized and deposited on the surface of cotton fabrics using ultrasound irradiation. Thus in the future we will try to treat infected wounds with transparent bandages coated with ZnO that will be applied to the wounds prior to irradiation.

    The article about the life and achievements of the apothecary Johann van Beethoven, the younger brother of the composer Ludwig van Beethoven, depicts a vivid picture of life in the 18th, 19t century. Research on archived original documents in Bonn, Vienna and Linz on the Danube made it possible to reveal details about the relationship inside this famous family and describes the hurdles of life of a successful apothecary. In 1776 Johann van Beethoven was born as the fourth child of the Beethoven family, a family of Bonner musicians. In 1790 he began his apprenticeship to become an apothecary at the Bonner "Hofapotheke". Towards the end of 1795 he moved to join his older brothers Ludwig and Karl in Vienna. During his time there he worked as a "subject" in various Viennese pharmacies. However in 1808 he purchased the pharmacy "Zur Goldenen Krone" in Linz on the Danube. His new pharmacy flourished, supplying first the Napoleonic occupation troops, and later the Austrian Military with medicines and field dressing/bandage materials. When in 1812 he married his Housekeeper, his Brother Ludwig opposed harshly, on reasons of social status and on moral grounds. Four years later, in 1816 Johann sold the pharmacy in Linz and founded a new pharmacy in Urfahr, on the opposite bank of the Danube. In 1819 he became a squire (or landowner), when he purchased a manor estate in Gneixendorf, near Krems on the Danube. In spite of his numerous duties as an apothecary and squire, Johann was frequently resident in Vienna, supporting his brother both emotionally and pharmaceutically. At the end of his life Johann sold both his pharmacy and the Gneixendorf estate, and spent his last years as a private gentleman living a dazzling lifestyle in Vienna. He died on January 12th 1848 and was buried in Vienna's "Waldmüllerpark".

    2012-10-01

    Chronic and acute infected wounds can pose a major clinical problem because of associated complications and slow healing. In addition to classic preparations for wound treatment, an array of modern dressings for chronic wound care are currently available on the market. These dressings are intended for the wounds due to intralesional physiological, pathophysiological and pathological causes and which failed to heal as expected upon the use of standard procedures. Classic materials such as gauze and bandage are now considered obsolete and of just historical relevance because modern materials employed in wound treatment, such as moisture, warmth and appropriate pH are known to ensure optimal conditions for wound healing. Modern wound dressings absorb wound discharge, reduce bacterial contamination, while protecting wound surrounding from secondary infection and preventing transfer of infection from the surrounding area onto the wound surface. The use of modern wound dressings is only justified when the cause of wound development has been established or chronic wound due to the underlying disease has been diagnosed. Wound dressing is chosen according to wound characteristics and by experience. We believe that the main advantages of modern wound dressings versus classic materials include more efficient wound cleaning, simpler placement of the dressing, reduced pain to touch, decreased sticking to the wound surface, and increased capacity of absorbing wound exudate. Modern wound dressings accelerate the formation of granulation tissue, reduce the length of possible hospital stay and facilitate personnel work. Thus, the overall cost of treatment is reduced, although the price of modern wound dressings is higher than that of classic materials. All types of modern wound dressings, their characteristics and indications for use are described.

    Wound healing is a complex biological process. Some injuries lead to chronic nonhealing ulcers, and healing process is a challenge to both the patient and the medical team. We still look forward an appropriate wound dressing. In this study, starch-based nanocomposite hydrogel scaffolds reinforced by zeolite nanoparticles (nZ) were prepared for wound dressing. In addition, a herbal drug (chamomile extract) was added into the matrix to accelerate healing process. To estimate the cytocompatibility of hydrogel dressings, fibroblast mouse cells (L929) were cultured on scaffolds. Then, 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium-bromide assay test and interaction of cells and scaffolds were evaluated. For evaluating healing process, 48 male rats were randomly divided into four groups of four animals each (16 rats at each step). The ulcers of the first group were treated with the same size of pure hydrogels. The second group received a bandage with the same size of hydrogel/extract/4 wt% nZ (hydrogel NZE). The third group was treated with chamomile extract, and the fourth group was considered as control without taking any medicament. Finally, the dressings were applied on the chronic refractory ulcers of five patients. After successful surface morphology and cytocompatibility tests, the animal study was carried out. There was a significant difference between starch/extract/4 wt% nZ and other groups on wound size decrement after day 7 ( P < 0.05). At the clinical pilot study step, the refractory ulcers of all five patients were healed without any hypersensitivity reaction. Starch-based hydrogel/zeolite dressings may be safe and effective for chronic refractory ulcers.

    The objective of this study was to determine adolescents' attitudes concerning the use of self-care and traditional medicines. A self-administered anonymous questionnaire with open-ended questions was completed by 543 adolescents aged 15-19 y. The results showed that the most frequent self-care activity for general health problems, in more than three-quarters of them, was self-medication; 14% of them resorted to minor home treatment such as taking care of wounds, bandaging or massages. Instructions for use were mentioned by 69% of adolescents as a way of choosing self-prescribed drugs. Natural medicines were used by 32% of the girls and 23% of the boys, mainly herbal teas or plant-based medicines, followed by homoeopathy. Self-care for emotional and relational problems mainly involved thinking about the problem and questioning themselves about their own behaviour or about the way they are. They also mentioned activities such as sports, going out, listening to music, watching television, and trying to think about something else by keeping themselves occupied. Natural medicines were used by 19% of the girls and 13% of the boys. Plant-based medicines or herbal teas were used most often, followed by drugs or alcohol, with homoeopathy in third place. Self-care and alternative medicines were used by adolescents in this study for physical as well as for emotional or relational problems. Their use did not reflect dissatisfaction with physicians and hospital treatment or an objection to formal services, but rather was a choice of these approaches for their own specific characteristics. They were also viewed as being less harmful than conventional treatment.

  4. Investigation of the effect of deprivation on the burden and management of venous leg ulcers: a cohort study using the THIN database.

    Full Text Available There has been limited examination of the contribution of socio-economic factors to the development of leg ulcers, despite the social patterning of many underlying risk factors. No previous studies were found that examined social patterns in the quality of treatment received by patients with leg ulcers.Using The Health Improvement Network (THIN database we identified a cohort of over 14000 patients with a diagnosis of venous leg ulceration, prospectively recorded between the years 2001 and 2006, with linked area-level socio-economic information (Townsend deprivation quintile. We assessed socio-economic differences in the incidence and prevalence of leg ulcers using negative binomial regression. Socio-economic differences in two key areas of guideline recommended leg ulcer management, arterial Doppler assessment and compression bandaging, were assessed using multilevel regression.The risk of incident venous leg ulceration increased for patients living in areas of higher deprivation, even after adjustment for known risk factors age and gender. Overall reported rates of Doppler assessment and provision of compression therapy were low, with less than sixteen per cent of patients having a database record of receiving these recommended diagnostic and treatment options. Patients diagnosed with incident venous leg ulcers living in the most deprived areas were less likely to receive the recommended Doppler-aided assessment for peripheral vascular disease than patients living in the least deprived areas (odds ratio 0.43, 95% confidence interval 0.24-0.78. Documented provision of compression therapy did not vary with deprivation.A socio-economic gradient in venous leg ulcer disease was observed. The overall rates of people with venous leg ulcers who were documented as receiving guideline recommended care (2001-2006 were low. Reported use of Doppler ultrasound assessment was negatively associated with socio-economic status. These findings suggest that the

    To compare data on time to healing from two separate cohorts: one treated with a new acellular synthetic matrix plus standard care (SC) and one matched from four large UK pragmatic, randomised controlled trials [venous leg ulcer (VLU) evidence network]. We introduce a new proof-of-concept strategy to a VLU clinical evidence network, propensity score matching and sensitivity analysis to predict the feasibility of the new acellular synthetic matrix plus SC for success in future randomised, controlled clinical trials. Prospective data on chronic VLUs from a safety and effectiveness study on an acellular synthetic matrix conducted in one wound centre in the UK (17 patients) and three wound centres in Australia (36 patients) were compared retrospectively to propensity score-matched data from patients with comparable leg ulcer disease aetiology, age, baseline ulcer area, ulcer duration, multi-layer compression bandaging and majority of care completed in specialist wound centres (average of 1 visit per week), with the outcome measures at comparable follow-up periods from patients enrolled in four prospective, multicentre, pragmatic, randomised studies of venous ulcers in the UK (the comparison group; VLU evidence network). Analysis using Kaplan-Meier survival curves showed a mean healing time of 73·1 days for ASM plus SC (ASM) treated ulcers in comparison with 83·5 days for comparison group ulcers treated with SC alone (Log rank test, χ 2 5·779, P = 0·016) within 12 weeks. Sensitivity analysis indicates that an unobserved covariate would have to change the odds of healing for SC by a factor of 1·1 to impact the baseline results. Results from this study predict a significant effect on healing time when using a new ASM as an adjunct to SC in the treatment of non-healing venous ulcers in the UK, but results are sensitive to unobserved covariates that may be important in healing time comparison. © 2016 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

  6. Dutch Venous Ulcer guideline update.

    2014-05-01

    The revised guideline of 2013 is an update of the 2005 guideline "venous leg ulcer". In this special project four separate guidelines (venous leg ulcer, varicose veins, compression therapy and deep venous disorders) were revised and developed simultaneously. A meeting was held including representatives of any organisation involved in venous disease management including patient organizations and health insurance companies. Eighteen clinical questions where defined, and a new strategy was used to accelerate the process. This resulted in two new and two revised guidelines within one year. The guideline committee advises use of the C of the CEAP classification as well as the Venous Clinical Severity Score (VCSS) and a Quality of life (QoL) score in the assessment of clinical signs. These can provide insight into the burden of disease and the effects of treatment as experienced by the patient. A duplex ultrasound should be performed in every patient to establish the underlying aetiology and to evaluate the need for treatment (which is discussed in a separate guideline). The use of the TIME model for describing venous ulcers is recommended. There is no evidence for antiseptic or antibiotic wound care products except for a Cochrane review in which some evidence is presented for cadexomer iodine. Signs of infection are the main reason for the use of oral antibiotics. When the ulcer fails to heal the use of oral aspirin and pentoxifylline can be considered as an adjunct. For the individual patient, the following aspects should be considered: the appearance of the ulcer (amount of exudate) according to the TIME model, the influence of wound care products on moisturising the wound, frequency of changing compression bandages, pain and allergies. The cost of the dressings should also be considered. Education and training of patients t improves compliance with compression therapy but does not influence wound healing rates. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Objective Elevated inflammatory cytokine levels have been implicated in the pathogenesis of non3 healing chronic venous insufficiency (CVI) ulcers. The goal of this study was to determine the protein levels of a wide range of inflammatory cytokines in untreated CVI ulcer tissue before and after 4 weeks of high strength compression therapy. These levels were compared to cytokines present in healthy tissue. Methods Thirty limbs with untreated CVI and leg ulceration received therapy for 4 weeks with sustained high compression bandaging at an ambulatory wound center. Biopsies were obtained from healthy and ulcerated tissue before and after therapy. A multiplexed protein assay was used to measure multiple cytokines in a single sample. Patients were designated as rapid or delayed healers based on ulcer surface area change. Results The majority of pro-inflammatory cytokine protein levels were elevated in ulcer tissue compared to healthy tissue, and compression therapy significantly reduced these cytokines. TGF-β1 was up-regulated in ulcer tissue following compression therapy. Rapid healing ulcers had significantly higher levels of IL-1α, IL-1β, IFN-γ, IL-12p40 and GM-CSF before compression therapy, and IL-1 Ra after therapy. IFN-γ levels significantly decreased following therapy in the rapidly healing patients. Conclusion CVI ulcer healing is associated with a pro-inflammatory environment prior to treatment that reflects metabolically active peri-wound tissue that has the potential to heal. Treatment with compression therapy results in healing that is coupled with reduced pro-inflammatory cytokine levels and higher levels of the anti-inflammatory cytokine IL-1 Ra. Clinical Relevance This data suggests that cytokines may provide targets in which topical therapeutic inhibition or promotion at appropriate time points in the healing process may provide novel therapeutic approaches to the healing of CVI ulcers.

    ABSTRACT Objective The aim of the study was to investigate the impact of stress, illness perceptions, and behaviors on healing of venous leg ulcers. Methods A prospective observational study of 63 individuals for 24 weeks investigated possible psychosocial predictors of healing. There were two indices of healing: rate of change in ulcer area and number of weeks to heal. Psychological variables were assessed at baseline using self-report measures (Perceived Stress Scale, Hospital Anxiety and Depression Scale, Revised Illness Perception Questionnaire, adapted Summary of Diabetes Self-Care Activities, Adherence Questionnaire, and Short-Form Health Survey). Results Controlling for sociodemographic and clinical variables, for the 24 weeks, a slower rate of change in ulcer area was predicted by greater stress (standardized β = −0.61, p = .008), depression (standardized β = −0.51, p = .039), and holding negative perceptions or beliefs about the ulcer (standardized β = −1.4, p = .045). By 24 weeks, 69% of ulcers had closed. A more negative emotional response to the ulcer at baseline (i.e., emotional representation of the ulcer) was associated with a greater number of weeks to heal (hazard ratio [HR] = 0.63, 95% confidence interval [CI] = 0.41-0.95, p = .028). Higher educational attainment (HR = 3.22, 95% CI = 1.37–7.55, p = .007) and better adherence to compression bandaging (HR = 1.41, 95% CI = 1.06–1.88, p = .019) were associated with fewer weeks to heal. No other psychosocial variable (stress, perceptions about the ulcer, health behaviors) predicted weeks to heal. Conclusions Alongside ulcer-related predictors, psychological and sociodemographic factors were associated with healing. Future research should explore mediating mechanisms underlying these associations and develop interventions to target these variables. PMID:27941577

    I-123 iodo-amphetamine (123-I-N-isopropyl-p-iodoamphetamine-EIR) seems a useful agent for the investigation of cerebral blood flow. As the indications on the time of cerebral equilibrium - i.e. the adequate moment of scanning varied according to several authors we realized a preliminary kinetic study in 6 and a brain ECT in 12 patients (11 males, 1 female). 2 patients were studied twice. 9 patients had vascular lesions, 3 brain metastases. Patients were studied after informed consent. After overnight fasting short catheters (venflon) were put in a vein of each forearm, one for the injection of the tracer, the other for blood sampling. Then the patients were allowed to rest in a dark room with a bandage over the eyes. 10 minutes later, the tracer (5 mCi) was injected and blood samples were taken at 5, 10, 15, 30, 45, 60, 90 and 120 minutes post injection. Whole body tracer distribution was measured with a dual head scintillation camera between 30 and 60 minutes as well as after 90 minutes post injection in 4 patients, in 2 patients only the second measurement was performed. Brain ECT was realized with a dual head rotating scintillation camera during the 50-90 minutes following injection at an angular increment of 6 0 and a counting time of 40-50 seconds per view (40000-60000 counts), this means about 30-35 minutes immobilization for the patient. The plasma diappearance curve presented two components in all (n=5) patients studied, the T 1/2 of the first being 45 +- 11.7 minutes, the second being a plateau or slightly ascending. All lesions on CT were visualized by ECT with iodoamphetmine, but they appeared larger on ECT. These findings have still to be verified in a group of patients with more discrete lesions as all patients of the group studied first had quite extensive lesions of the brain. (Author)

    Infection rates following ankle fractures are as high as 19% in selected material and is the most common complication following this type of surgery, with potential catastrophic consequences. The purpose of this study was to test a regime of intermittent pneumatic compression, a compression bandage and a compression stocking and its effect on the rate of wound complications. The hypothesis was that compression could lower the infection rate from 20 to 5%. We performed a randomized, controlled, non-blinded trial, including 153 adult patients with unstable ankle fractures. Patients were randomized to either compression (N = 82) or elevation (N = 71). Patients with open fracture, DVT, pulmonary embolism, dementia, no pedal pulse, or no Danish address were excluded. Primary endpoint was infection. Secondary endpoints were necrosis and wound dehiscence. After 2 weeks, 1.4% (0.0;7.6) in the compression group had infection compared to 4.6% (1.0;12.9) in the control group, p = 0.35. The rate of necrosis after 2 weeks was 7.0% (95% CI 2.3;15.7) in the compression group compared with 26.2% (95% CI 16.0;38.5) in the elevation group, p = 0.004. No difference was shown regarding wound dehiscence. Based on this study, we cannot conclude if compression therapy prevents infection or not. This is mainly due to under-powering of the study. The effect on necrosis was in favor of compression, but the trial was not powered to show a difference regarding this endpoints and the result is thus hypothesis generating. Further research is needed before a thorough recommendation on the use of compression treatment that can be made.

    Describe and analyze nursing activity in rheumatology. A cross-sectional study was performed in Spanish rheumatology departments. Results were based on surveys administered to rheumatology nurses. We included variables on socio-demographics, the setting and available resources, and the activities they carried out. Each activity was compared in terms of workplace, available resources and dedication exclusively to one field. Sixty-seven surveys were collected from 57 hospitals in 17 Spanish autonomous communities. 97% of the nurses were women, with an average age of 48.9 years and an average nursing experience of 6 years. 56% of the professionals had gained their experience in outpatient clinics, 35% in day hospitals and 9% in inpatient and primary care. As for the availability of resources, 59% had their own office, 77.3% had a phone listing and 60% scheduled and conducted patient visits. Of the 19 activities included, those performed by the highest number of nurses were managing, monitoring and coordinating the use of biological drugs (90.9%), therapy monitoring (89.4%) and training patients in self-medication (89.4%). The activity in which nurses most frequently collaborated with physicians was the administration of local injections (51.5%). Other activities were teaching (50%) and research (78.8%) in their departments and studies in the nursing field (51.5%). Work in outpatient clinics versus day hospitals showed statistically significant differences for health education, nutrition, splinting and bandaging, and collaboration in ultrasound studies. These professionals performed a greater number of activities when they worked in outpatient clinics, had their own office and worked exclusively in rheumatology.

    In the recent years, radiation-induced graft polymerization of various monomers onto different types of trunk polymers have been extensively used for researchers on adsorbents for cations, anions and different compounds, battery separators, antibacterial bandages, protein separators, and fuel cell applications. Some of these technologies were transferred to end-users and eventually commercialized. In most of these studies, a post-grafting reaction is performed to introduced chemical groups that impart functionality to the grafted material. In this paper, pre-irradiation technique was used for emulsion grafting of glycidyl methacrylate (GMA) onto an electron beam irradiated abaca-polyester nonwoven fabric (APNWF). The dependence of degree of grafting (Dg), calculated from the weight of APNWF before and after grafting, on irradiation dose, reaction time and monomer concentration were studies. After 50 kGy irradiation with 2 MeV electron beam and subsequent 3-hour reaction with an emulsion consisting of 5% GMA and 0.5% polyoxyethylene sorbitan monolaurate (Tween 20) surfactant in deionized water at 40 degree centegrade, a grafted APNWF with a Dg greater than 150% was obtained. The GMA grafted APNWF was further modified by reaction with ethylenediamine (EDA) in isopropyl alcohol at 60 degree centegrade to introduce amine functional groups. A 3-hour reaction with 50% EDA resulted to an amine group density of 2.7 mmole/gram-adsorbent. Preliminary batch adsorption experiments using Cu 2+ and Ni 2+ ions in aqueous solutions show that the adsorption capacity of the grafted adsorbent is four times greater for Cu 2+ ions compared to Ni 2+ ions.

    Objective: To investigate the effect of reducing scan dose on the lung nodules detection rate by scanning a lung nodule model at low dose and conventional dose. Methods: The lung and the thoracic cage were simulated by using a cyst filled with water surrounded by a roll bandage. Flour, butter, and paraffin wax were mixed together by a certain ratio to simulate lung nodules of 10 mm and 5 mm in diameter with the CT values ranging from -10 to 50 HU. Conventional-dose scan (240 mA, 140 kV) and low-dose scan of three different levels (43 mA, 140 kV; 50 mA, 120 kV; 75 mA, 80 kV) together with three different pitches (1.0, 1.5, and 2.0) were performed. The images of the simulated nodules were combined with the CT images of a normal adult's upper, middle, and inferior lung. Three radiologists read the images and the number of the nodules they detected including both the real ones and the false-positive ones was calculated to investigate weather there was any difference among different doses, pitch groups, and different locations. Results: The detection rate of the 10 mm and 5 mm nodules was 100% and 89.6% respectively by the low-dose scan. There was no difference between low-dose and conventional-dose CT (χ 2 =0.6907, P>0.70). The detection rate of 5 mm nodules declined when large pitch was used. Conclusion: The detection rates of 10 mm and 5 mm nodules had no difference between low-dose CT and conventional-dose CT. As the pitch augmented, the detection rate for the nodules declined

    Full Text Available A 15-year-old Selle Francais gelding was presented to the equine referral hospital for treatment of a left guttural pouch mycosis previously diagnosed. After induction, the horse was shortly hoisted by all four feet, moved on a padded surgical table, and positioned in right lateral recumbency. In order to reduce the risk of bleeding during surgical manipulation of the carotid and maxillary arteries, a mean arterial pressure between 60 and 70 mmHg was targeted. After surgery, the horse was moved in a padded recovery box keeping the same lateral recumbency. Four unsuccessful attempts were performed, with the horse always returning to sternal recumbency keeping the left hind limb up. At the fifth attempt, performed 120 min after the end of the general anesthesia, the horse stood up correctly but moderate ataxia and absence of weight bearing on the left hind limb were shown. Both the stifle and the fetlock joint were held in a flexed position and could not be extended properly in order to set the foot on the ground, resulting in a very short step. The horse was calm, not sweating, and willing to move; the muscles of the affected limb were relaxed, and the limb was neither warm nor painful at palpation. Occasionally, the horse flexed the affected hind limb in an exaggerated motion with marked abduction. No additional laboratory analyses were performed. Due to a strong suspicion of neuropathy, a sling support was initiated and a supportive bandage associated with flunixine administration was performed until resolution of the symptoms. The horse fully recovered after 3 days. This case report does not clarify the pathogenesis of the possible postanesthetic neuropathy accounted on the non-dependent limb, highlighting the need for future research in this field. Non-dependent limb neuropathy should be an expected problem even after having ruled out the most commonly known causes predisposing to postanesthetic lameness.

    Lack of antibacterial activity, deficient water vapor and oxygen permeability, and insufficient mechanical properties are disadvantages of existing wound dressings. Hydrogels could absorb wound exudates due to their strong swelling ratio and give a cooling sensation and a wet environment. To overcome these shortcomings, flexible nanocomposite hydrogel films was prepared through combination of zinc oxide impregnated mesoporous silica (ZnO-MCM-41) as a nano drug carrier with carboxymethyl cellulose (CMC) hydrogel. Citric acid was used as cross linker to avoid the cytotoxicity of conventional cross linkers. The prepared nanocomposite hydrogel was characterized using X-ray diffractometry (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Zeta potential and UV-vis spectroscopy. Results of swelling and erosion tests showed CMC/ZnO nanocomposite hydrogel disintegrated during the first hours of the test. Using MCM-41 as a substrate for ZnO nanoparticles solved this problem and the CMC/ZnO-MCM-41 showed a great improvement in tensile strength (12%), swelling (100%), erosion (53%) and gas permeability (500%) properties. Drug delivery and antibacterial properties of the nanocomposite hydrogel films studied using tetracycline (TC) as a broad spectrum antibiotic and showed a sustained TC release. This could efficiently decrease bandage exchange. Cytocompatibility of the nanocomposite hydrogel films has been analyzed in adipose tissue-derived stem cells (ADSCs) and results showed cytocompatibility of CMC/ZnO-MCM-41. Based on these results the prepared CMC nanocomposite hydrogel containing ZnO impregnated MCM-41, could serve as a kind of promising wound dressing with sustained drug delivery properties.

    Júlio Rocha PIMENTA

    Full Text Available ABSTRACT Background The efficacy of nonselective β-blocker and endoscopic procedures, such as endoscopic variceal ligation, as primary prophylaxis of variceal hemorrhage in cirrhotic adults was demonstrated by numerous controlled trials, but in pediatric population, few are the number of studies. Objective The objective of this study is to evaluate the primary prophylaxis with β-blocker in cirrhotic children and adolescents with portal hypertension. Methods This is a cohort study encompassing 26 cirrhotic patients. β-blocker prophylaxis was performed with propranolol. When contraindicated the use of β-blocker, or if side effects presents, the patients were referred to endoscopic therapy with band ligation. Patients were evaluated by endoscopy, and those who had varicose veins of medium and large caliber or reddish spots, regardless of the caliber of varices, received primary prophylaxis. Results Of the 26 patients evaluated, 9 (34.6% had contraindications to the use of propranolol and were referred for endoscopic prophylaxis. Six (35.3% of the 17 patients who received β-blocker (propranolol, had bled after a median follow-up time of 1.9 years. β-blockage dosage varied from 1 mg/kg/day to 3.1 mg/kg/day and seven (41.2% patients had the propranolol suspended due to fail of the β-blockage or adverse effects, such as drowsiness, bronchospasm and hypotension. Patients who received endoscopic prophylaxis (elastic bandage had no bleeding during the follow-up period. Conclusion All of the patients that had upper gastroinstestinal bleeding in this study were under propranolol prophylaxis. The use of propranolol showed a high number of contraindications and side effects, requiring referral to endoscopic prophylaxis. The endoscopic prophylaxis was effective in reducing episodes of bleeding.

    Full Text Available Graduated compression devices are considered the standard care for management of venous and lymphatic disorders. Recently compression devices exerting a pressure over the calf higher than over the ankle have been proved to be more effective than traditional graduated devices in increasing the impaired ejection fraction (EF from the lower leg in patients with venous disease. Aim of this work is presenting an overview of the new concept on progressive compression, its potential benefits and limits. In different series of tests, the EF from the lower leg was assessed in 70 patients with severe reflux in the great saphenous vein (GSV. EF was measured by strain gauge plethysmography, in baseline conditions and after applying graduated compression devices or the new inversely graduated or progressive compression (PC devices. The interface pressure was recorded, simultaneously with the EF, both in the gaiter area (B1 point and at the calf (C point in order to assess the compression pressure profile. EF, severely impaired in patients with GSV reflux, was increased by compression. So called PC devices (both PC elastic stocking and PC inelastic bandages were significantly more effective than graduated compression in increasing the ejection fraction. The higher the pressure on the calf the higher the EF improvement. Maintaining the same strong pressure over the calf by means of two progressive stockings and increasing the pressure only over the calf to restore a graduated compression didn’t improve the EF. To improve venous pumping function in the ambulant patient stronger compression of the calf is more effective than graduated compression. This can be explained by the higher amount of blood volume pooled in the calf veins.

    Implantation of a total hip endoprosthesis with minimal trauma to the soft tissue. The need for visual aids (e.g., navigation or X-rays) during the procedure is frequently avoided. All kinds of coxarthrosis for every age group, for every variation of bone construction, and even in obese patients. Extremely dysplastic hip joints involving the development of a secondary socket and the necessity of reconstruction of the acetabular socket (e.g., in the Harris method). Using a fixed lateral position, a small entry incision is made between the tensor fasciae latae and the sartorius muscles and the prosthesis socket is put into place. Via a second dorsal incision, after stripping the exterior rotators, the prosthesis stem and ball are implanted and the two parts of the prosthesis are attached. Full weight bearing allowed immediately. A luxation prophylaxis, in the form of a self-developed hip bodice (the so-called Yale bandage), is used until the end of the 4th postoperative week. Discharge from hospital is possible after just a few days. Upon discharge, the patient is sent to a rehabilitation facility, either as a resident or as an outpatient, for approximately 3 weeks. Return to the workplace, with only light physical activity, is possible once the wound has healed completely; this could be as soon as 14 days after the operation. Checkups are made after 4 weeks, 6 months, 1 year and then every year; these checkups include a full examination, X-rays and laboratory tests. Full exposure to sport or heavy manual labor is usually approved after the 6-month checkup. Between October 2004 and April 2006, a total of 221 patients underwent surgery using this new technique (of these 15 patients underwent two-stage bilateral hip joint replacements). Patients were followed up for a minimum of 12 months and a maximum of 30 months. The Harris Hip Score improved from an average of 45.25 preoperatively to 96.4 postoperatively.

    The Global Alliance for the Elimination of Lymphatic Filariasis (GAELF) has recommended exploring local health traditions of skin care and a low cost treatment paradigm for rural communities has been proposed by Vaqas and Ryan. Our case study incorporates these promising treatments for use in treating filariasis in rural communities. Patients having lymphedema of one or both lower limbs (skin: normal, thickened or with trophic/warty changes) received treatment components from ayurveda, yoga and biomedicine simultaneously: including soap wash, phanta soaking, Indian manual lymph drainage (IMLD), pre- and post-IMLD yoga exercises, and compression using bandages for 194 days, along with diet restrictions and oral herbal medicines indicated for "elephantiasis" in Ayurveda. Entry points when infected were treated with biomedical drugs. The study was conducted in the reverse pharmacology design. 112 patients and 149 lower limbs completed 194 days of treatment during 2003-2006. Significant improvements were observed in the limb circumference measurements and the frequency of acute dermatolymphangioadenitis, use of preventive antibiotics, and reduction in the number of entry points were also improved. The objective to obtain significant benefit for a common problem using locally available, sustainable and affordable means has been achieved. It has not been our purpose to show that the regimen employed is better than another but the results do pose the question--"Are there components of Ayurvedic medicine that deserve further study?" It is important to understand that the regimen has been delivered mostly at home and that participants we have treated, representing a population suffering from a common problem, have not had access to effective conservative therapy that is culturally acceptable, safe, and efficacious.

  20. Managing Cutaneous Tuberculosis: A Case Report.

    2017-07-01

    Tuberculosis (TB) continues to be a prevalent disease worldwide; an estimated one third of the world's population is infected and 2015 data from the World Health Organization show 10 million people had an active infection. Although TB often is cited as a disease that most commonly occurs in underdeveloped countries, the evolution of drug-resistant forms of TB and infection sensitivity of immunocompromised individuals have made this disease a focal point for indus- trialized countries as well. When TB is spread, it commonly affects the lungs, but it can infect any organ of the body. An uncommon version - cutaneous TB - affects man with multiple comorbidities, including peripheral vascular disease and a remote history of travel to Latin America who presented to a wound care clinic with a 2-year history of painful shallow necrotic ulcers on his right lower limb and previous treatments that included a positive response to antibiotics. Once TB was con rmed via 2 posi- tive Quantiferon Gold tests, the patient received therapy (directly observed by the state health department) that included pyrazinamide, rifampin, ethambutol, isoniazid, and undocumented vitamin B6. Treatment for the TB-related lesions, con- comitant cellulitis, and a Stage 2 pressure injury under his rst right metatarsal head was initiated as well. The patient received local wound care for 40 days that included sharp debridement, of oading for the pressure injury, and pain relief before treatment at the wound care clinic and daily as prescribed by his primary care provider. All wounds were securely covered with collagen dressings followed by silicone-bordered bandages. Local wound care was provided for 40 days, with biweekly follow-up for an additional 30 days. The wounds resolved and the patient was discharged from the wound care clinic but remained on the caseload for 30 days in the event his pain increased or the wounds recurred. Cutaneous TB, uncommon and challenging, should be a consideration in

    A case of life threatening envenoming by a wild specimen of the inland taipan, Oxyuranus microlepidotus, is described. There have been 11 previously well-documented envenomings by O. microlepidotus, but only 2 were inflicted by wild snakes. Envenomed patients have presented predominantly with defibrinating coagulopathy and neurotoxicity. The victim was seeking to observe members of an isolated population of this species and was envenomed while attempting to photograph an approximately 1.5 m specimen. He reported feeling "drowsiness" and blurred vision that progressed to ptosis; he later developed dysphagia and dysarthria. The patient was treated with 1 vial of polyvalent antivenom, which was later followed with an additional two vials of taipan monovalent. He was intubated during retrieval, and recovered after 3 days of intensive care. He had a right ophthalmoplegia that persisted for approximately 1 week post-envenoming. Despite a positive 20-min whole blood clotting test, defibrination coagulopathy was absent, and there was no myotoxicity, or acute kidney injury. Physicians presented with a patient envenomed by O. microlepidotus should remain cognizant of the possible variability of medically important venom toxins in some populations of this species. Some patients seriously envenomed by this species may develop persistent cranial nerve palsies. When clinically indicated, prompt provision of adequate antivenom is the cornerstone of managing O. microlepidotus envenoming. Rapid application of pressure-bandage immobilization and efficient retrieval of victims envenomed in remote locales, preferably by medically well-equipped aircraft, probably improves the likelihood of a positive outcome.

    The Bundled Payments for Care Improvement initiative combines payment of multiple services for episodes of care into 1 bundle. Rotator cuff repair is a likely candidate for future inclusion. The objective of this study was to determine cost-effective, high-quality postoperative rehabilitation dosing and cryotherapy for patients undergoing rotator cuff repair based on systematic review of the literature. Systematic review of level I and level II articles was performed in PubMed, Cochrane Databases, and PEDro. Conference references and bibliographies were also reviewed. For postoperative therapy, keywords included rotator cuff, rotator cuff repair, exercise therapy, exercise, unsupervised, self-care, postoperative period, physical therapy, and physiotherapy; for cryotherapy, keywords included rotator cuff repair, shoulder, cryotherapy, and ice. Five studies compared postoperative outcomes in participants assigned to supervised therapy vs. unsupervised therapy. Three found no difference between groups. One found improved outcomes in supervised therapy. Limitations included that therapies were not consistently defined and significant methodologic issues were present, decreasing the applicability and validity of the results. Five articles examined cryotherapy outcomes in the postoperative shoulder. Two studies showed improved patient outcomes with cryotherapy vs. no cryotherapy; 2 studies showed no decrease in joint space temperatures at 90 minutes but decrease in temperature at 4 to 23 hours postoperatively. One study indicated that an ice bag and Ace bandage might be as effective as continuous, compressive cryotherapy units using patient-reported outcomes. Further studies are needed to determine effective dosing of physical therapy after rotator cuff repair. Cryotherapy is favorable and cost-effective using simple methods for delivery.

    The purpose of this study was to peer review the implementation of protective measures to limit public exposure surveillance zone NPP in case of emergency considering laws and regulations. Survey method using expert assessments were used. Experts were formed in four groups who are respon sible for radiation protection of various groups surveillance zone of RNPP. Requirements to selections experts were professional experience not less than 10 years, the profile and post. For primary empirical data was used simple ordering of values of an even or consistent comparison. According to experts, measures warning, provision of stable iodine preparations, provision of collective (protective constructions, hiding place) and personal protective equipment (clothing, gauze bandages, respirators, mask), material and technical equipment at the Rivne NPP could be significantly different in rural and urban sur veillance zone in the case of emergency. Group risk in case of an emergency, can become students of rural schools surveillance zone due to imperfect warning system and lack of shelter facilities. There is no consensus among experts on radiation protection assessments of various groups surveillance zone, including provision of means of individual and collective protection, preparedness protective actions in case of emergency. State radiation protection surveillance zone Rivne NPP, including a system of organizational, techni cal, biomedical, financial and economic measures to prevent and respond to the National Assembly, does not meet the laws of Ukraine "On Nuclear Energy Use and Radiation Safety" and "On protection of population and territories from emergency situations of technogenic and natural character ", requiring State Nuclear Regulatory Inspectorate (SNRI) of Ukraine on this question.

    Second-intention healing of limb wounds in horses is often problematic. Solcoseryl is a protein-free, standardized dialysate/ultrafiltrate (HD) derived from calf blood, which has been shown to improve healing in both animals and humans. The efficacy of HD in the healing of deep wounds in horses and ponies was investigated. Deep wounds of 20 by 35 mm were created on both metatarsi (skin, subcutis, periosteum) and on both femoral biceps muscles (skin, subcutis, muscle) of five horses and five ponies. The wounds on one side were treated with HD, four times a week during the period that the wounds were bandaged and once daily thereafter. The wounds on the other side were left untreated. In the first 4 weeks of the healing period HD stimulated healing but inhibited healing thereafter. This pattern was significant for all wound groups (P < 0.001). Because of this change in effect, the overall effect on wound healing over the entire period was not significant (P = 0.77). HD stimulated healing initially by provoking a greater initial inflammatory response, faster contraction and faster formation of granulation tissue. Subsequently, HD inhibited healing because it significantly delayed epithelialization and caused protracted inflammation. The effects of HD were most pronounced in the horses. Because this study distinguished between contraction and epithelialization, it could be shown that HD stimulated contraction but inhibited epithelialization. Therefore, HD is useful in horses for the treatment of deep wounds during the initial phase of healing by second intention, i.e. during the first weeks when wound contraction can be expected. Treatment should be ceased when epithelialization becomes predominant.

    This study investigated the performance of a new gelling fibre dressing containing silver (DURAFIBER™ Ag; Smith & Nephew, Hull, UK) in moderate to highly exuding venous leg ulcers with one or more clinical signs of infection. Fourteen patients with venous leg ulceration of median ulcer duration 12·5 weeks, recruited from three centres in South Africa, received treatment with the new dressing for a maximum of 8 weeks. Multilayer compression bandaging was used for all patients, at the majority of assessments. The objectives of this study were to assess the clinical acceptability of the dressing in terms of the following characteristics: antimicrobial properties, the progress of the wound towards healing, wear time, exudate management, conformability, patient comfort, pain on application, pain on removal and dressing integrity. The new dressing was rated as clinically acceptable for all characteristics, for all 14 patients (100%). It was easy to apply and remove; in 96·8% of removals, the dressing stayed intact on removal and could be removed in one piece. Fifty per cent of the wounds healed within the 8-week study duration; between baseline and final assessment, the median percentage reduction in wound area was 98·2% and the median percentage reduction in devitalised tissue was 78%. Exudate levels and wound pain were significantly improved at final assessment compared to baseline assessment, and an increase in the number of patients with healthy peri-wound skin between baseline and final assessment was observed. A reduction in bioburden and signs of clinical infection and an improvement in quality of life were observed over the 8-week period. The average wear time was 6·4 days. This study supports the use of new dressing in the management of moderately to highly exuding venous leg ulcers with clinical signs of infection. © 2014 The Authors.

    OSCEs (Objective Structured Clinical Examinations) are widely used in health professions to assess clinical skills competence. Raters use standardized binary checklists (CL) or multi-dimensional global rating scales (GRS) to score candidates performing specific tasks. This study assessed the reliability of CL and GRS scores in the assessment of veterinary students, and is the first study to demonstrate the reliability of GRS within veterinary medical education. Twelve raters from two different schools (6 from University of Calgary [UCVM] and 6 from Royal (Dick) School of Veterinary Studies [R(D)SVS] were asked to score 12 students (6 from each school). All raters assessed all students (video recordings) during 4 OSCE stations (bovine haltering, gowning and gloving, equine bandaging and skin suturing). Raters scored students using a CL, followed by the GRS. Novice raters (6 R(D)SVS) were assessed independently of expert raters (6 UCVM). Generalizability theory (G theory), analysis of variance (ANOVA) and t-tests were used to determine the reliability of rater scores, assess any between school differences (by student, by rater), and determine if there were differences between CL and GRS scores. There was no significant difference in rater performance with use of the CL or the GRS. Scores from the CL were significantly higher than scores from the GRS. The reliability of checklist scores were .42 and .76 for novice and expert raters respectively. The reliability of the global rating scale scores were .7 and .86 for novice and expert raters respectively. A decision study (D-study) showed that once trained using CL, GRS could be utilized to reliably score clinical skills in veterinary medicine with both novice and experienced raters.

    The purpose of this study was to compare the degree of increase in middle cerebral artery (MCA) blood flow velocity after tourniquet deflation when modulating hyperventilation during orthopedic surgery under sevoflurane, isoflurane, or propofol anesthesia. Twenty-four patients undergoing elective orthopedic surgery were randomly divided into sevoflurane, isoflurane, and propofol groups. Anesthesia was maintained with sevoflurane, isoflurane, or propofol administration with 33% oxygen and 67% nitrous oxide at anesthetic drug concentrations adequate to maintain bispectral values between 45 and 50. A 2.0-MHz transcranial Doppler probe was attached to the patient's head at the temporal window, and mean blood flow velocity in the MCA (V (mca)) was continuously measured. The extremity was exsanguinated with an Esmarch bandage, and the pneumatic tourniquet was inflated to a pressure of 450 mmHg. Arterial blood pressure, heart rate, V (mca) and arterial blood gases were measured every minute for 10 min after release of the tourniquet in all three groups. Immediately after tourniquet release, the patients' respiratory rates were increased to tightly maintain end-tidal carbon dioxide (PetCO(2)) at 35 mmHg. No change in partial pressure of carbon dioxide in arterial blood (PaCO(2)) was observed pre- and posttourniquet deflation in any of the three groups. Increase in V (mca) in the isoflurane group was greater than that in the other two groups after tourniquet deflation. In addition, during the study period, no difference in V (mca) after tourniquet deflation was observed between the propofol and sevoflurane groups. Hyperventilation could prevent an increase in V (mca) in the propofol and sevoflurane groups after tourniquet deflation. However, hyperventilation could not prevent an increase in V (mca) in the isoflurane group.

    The purpose of this study was to examine the comparative effects of sevoflurane, isoflurane or propofol on cerebral blood flow velocity after tourniquet deflation during orthopaedic surgery. Thirty patients undergoing elective orthopaedic surgery were randomly divided into sevoflurane, isoflurane and propofol groups. Anaesthesia was maintained with sevoflurane, isoflurane or propofol infusion in 33% oxygen and 67% nitrous oxide, in whatever concentrations were necessary to keep bispectral index values between 45 and 50. Ventilatory rate or tidal volume was adjusted to target PaCO2 of 35 mmHg. A 2.0 MHz transcranial Doppler probe was attached to the patient's head at the temporal window and mean blood flow velocity in the middle cerebral artery was continuously measured. The extremity was exsanguinated with an Esmarch bandage and the pneumatic tourniquet was inflated to a pressure of 450 mmHg. Arterial blood pressure, heart rate, velocity in the middle cerebral artery and arterial blood gas analysis were measured every minute for 10 minutes after release of the tourniquet in all three groups. Velocity in the middle cerebral artery in the three groups increased for five minutes after tourniquet deflation. Because of the different cerebrovascular effects of the three agents, the degree of increase in flow velocity in the isoflurane group was greater than in the other two groups, the change in flow velocity in the propofol group being the lowest (at three minutes after deflation 40 +/- 7%, 32 +/- 6% and 28 +/- 10% in the isoflurane, sevoflurane and propofol groups respectively, P < 0.05).

    Patients recovering from critical illness especially those with critical illness related neuropathy, myopathy, or burns to face, arms and hands are often unable to communicate by writing, speech (due to tracheostomy) or lip reading. This may frustrate both patient and staff. Two low cost movement tracking systems based around a laptop webcam and a laser/optical gaming system sensor were utilised as control inputs for on-screen text creation software and both were evaluated as communication tools in volunteers. Two methods were used to control an on-screen cursor to create short sentences via an on-screen keyboard: (i) webcam-based facial feature tracking, (ii) arm movement tracking by laser/camera gaming sensor and modified software. 16 volunteers with simulated tracheostomy and bandaged arms to simulate communication via gross movements of a burned limb, communicated 3 standard messages using each system (total 48 per system) in random sequence. Ten and 13 minor typographical errors occurred with each system respectively, however all messages were comprehensible. Speed of sentence formation ranged from 58 to 120s with the facial feature tracking system, and 60-160s with the arm movement tracking system. The average speed of sentence formation was 81s (range 58-120) and 104s (range 60-160) for facial feature and arm tracking systems respectively, (Pcommunication aids in patients in general and burns critical care units who cannot communicate by conventional means, due to the nature of their injuries.

    Platelet-rich fibrin (PRF) promotes tissue regeneration by releasing various growth factors. The palatal donor site of the epithelialized connective tissue (CT) graft significantly influences the patient's morbidity. The aim of this study is to compare the effects of PRF and gelatin sponge on the healing of palatal donor sites and the patient's morbidity. Forty patients with at least one site of Miller Class I or II gingival recession were treated by a coronally advanced flap with CT graft resulting from the de-epithelialization of a free gingival graft. In the test group (20 patients), a PRF membrane was placed over the palatal wounds; conversely, the 20 control group patients were treated with an absorbable gelatin sponge. Patients were monitored at 1, 2, 3, and 4 weeks after surgery for the complete re-epithelialization of the palatal wound (CWE), the alteration of sensitivity around the wound area, postoperative discomfort, and changes in feeding habits (CFH). Furthermore, the consumption of analgesics during the postoperative week 1 was assessed. The test group showed a significantly faster CWE (P <0.001); 35% of the test patients showed CWE at the end of week 2 (controls, 10%), whereas at the end of week 3, all palatal wounds in the test patients epithelialized completely (controls, 25%). Similarly, test patients reported significantly less discomfort and CFH (P ≤ 0.02) and took a significantly lower dose of analgesics (P = 0.02). The PRF-enriched palatal bandage significantly accelerates palatal wound healing and reduces the patient's morbidity.

    Short-term effects of therapeutic claw trimming in acutely lame cows (n=21) with nonadvanced claw horn lesions on the endocrine, metabolic, and behavioral stress responses were investigated in comparison to regular claw trimming in nonlame control cows (n=21). Controls were matched to lame cows by parity and stage of lactation. Lame cows suffering from typical sole ulcers or white line disease were blinded and randomly assigned to 2 treatments, receiving 15 min before interventions either ketoprofen (n=11; 3mg/kg of BW intramuscularly; Romefen, Merial, Lyon, France) or placebo (n=10; saline in equivalent amount and route of administration). All cows underwent functional claw trimming in lateral recumbency on a surgical tipping table, and claw horn lesions in lame cows were conventionally treated (removal of loose horn, block on opposing claw, bandaging of affected claw). Blood samples collected 15 min before, at the end, and 24h after claw trimming were analyzed for concentrations of cortisol, fatty acids, lactate, and glucose, and fecal samples (collected before treatment and after 24 h) for cortisol metabolites. Behavioral stress responses during functional and therapeutic claw trimming were recorded. Concentrations of blood cortisol, fatty acids, glucose, and fecal cortisol metabolites were higher in lame than in nonlame cows after treatment. During claw treatment, more leg movements were recorded for lame cows than nonlame cows. Pre-emptive administration of ketoprofen had no obvious effects on stress responses to therapeutic claw trimming. Treatments of claw horn lesions caused a significant stress and pain reaction in acutely lame cows, demonstrating the necessity of adequate pain management protocols for such interventions.

    The surgical treatment for giant neurofibromatosis-1 (NF-1) requires comprehensive measures. Presently, there is no systematic description of surgical treatment. Because of its high level of risk, we want to share our clinical experience. From 2011 to 2014, patients (n = 8, 5 female and 3 male patients, aging from 31 to 45 years-old) were included in the study. The tumours were located on the trunk (n = 5) or face (n = 3). In addition to routine examination, blood storage was also prepared. Preoperative consultation from related departments was critical at first. Related artery embolisation was also carried out. In the operation, we checked thromboelastography, based on which reasonable blood component transfusion was implemented. Autologous blood transfusion was also ready. An instrument of copper needle or ring ligation was used to reduce haemorrhage before the surgery. Protruding or drooping portions of the tumours were excised. A pressurised bandage was applied when the surgery was completed. After the surgery, besides the routine monitoring of vital signs, re-haemorrhage should be detected in time. Then, we should decide whether blood transfusion or surgery was required again. Expanders were implanted in one female patient with facial injuries before removing the tumour. Then, expanded flaps were applied to repair the secondary wound. According to the above clinical route, after an average of 1-year follow-up, no patients died, and other unforeseen events did not occur. Wounds healed well in all patients. The tumor was excised as much as possible. No facial nerve paralysis occurred in the facial sites. Expanded flaps necrosis WAS not encountered. It is essential to design the educational clinical route for treating NF-1 when a giant protruding tumour is advised to be excised, which can minimise the risk of surgery and assure us of the maximum range of resection. © 2016 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

    Health care demand due to animal bites is frequent, especially in the emergency department (ED). In addition to the physical trauma caused by bites, one should be concerned with infectious diseases that can be transmitted. The range of the lesions depends on the animal species. Bites of Hydrochoerus hydrochaeris (capybaras) in humans are relatively uncommon. Capybaras are docile animals; however, their large rodent incisive teeth could cause serious injury. Localized care, antibiotic therapy when necessary, careful examination of the structures, tetanus and rabies immunization as indicated, and follow-up are recommended for wild animal bites. The authors hereby describe and discuss the medical management of a case of multiple lesions from capybara bites on the right thigh of a man. A 54-year-old male patient was admitted to the ED with a compression bandage soaked with blood after being bitten by a capybara. At the clinical examination, the patient had two lacerating wounds and multiple abrasions on the anterior face of the right thigh. Rabies prophylaxis was administered and the wounds were irrigated and closed with sterile dressings. Oral amoxicillin/clavulanate potassium for 7 days was administered to the patient. The patient was followed up; 3 months after the attack he returned to his previous level of activity without any complication. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: We recommend that practitioners and physicians should provide prompt attention due to potentially significant morbidities, particularly rabies. The adequate care of the wound will allow better aesthetic and functional results to victims of wild animal bites. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Jean Stafford’s short story “The Interior Castle” (1946 and Sylvia Plath’s “Face Lift” and “The Plaster”, written in the early 1960s but published posthumously in Crossing the Water (1971, dwell on a theme which is rarely tackled in Postwar American literature: plastic surgery. Using a markedly mnemonic tone, both authors trace in detail the passive submission of female bodies to male (reconstruction. While the history of women in early Cold War America is usually associated with the patriarchal mystifying of housewifery, the myth of ideal, domestic femininity was also intimately related to bodily beauty. The demand for physical “perfection” which resulted from constructing women as, primarily, objects of male desire was mirrored in popular magazines, such as Ladies’ Home Journal, which endorsed women’s seeking medical aid to model themselves into “ideal” sexual mates (Meyerowitz in Meyerowitz ed., 244. Women’s submission to the notion that they should use any means necessary to become aesthetic objects to be appraised by men was thus represented as desirable. In this paper, I shall trace how both Stafford and Plath adopted a confessional style of writing in the abovementioned pieces in order to denounce the cultural construction of women as passive bodies to be moulded at will, instead of as active, thinking subjects. I shall argue that by reproducing the recollections and thoughts of the women being stitched, sewn and bandaged in their pieces, both authors articulated an alternative protofeminist aesthetics based on the beauty of what Stafford described as “inscrutable intelligence”.

    Full Text Available Jan K Shearer,1 Paul J Plummer,1,2 Jennifer A Schleining11Veterinary Diagnostic and Production Animal Medicine, College of Veterinary Medicine, Iowa State University, Ames, IA, USA; 2Veterinary Microbiology and Preventive Medicine, College of Veterinary Medicine, Iowa State University, Ames, IA, USAAbstract: Lameness is a leading cause of welfare and culling issues in cattle, with claw lesions accounting for the majority of these issues. Although the treatment of claw lesions in cattle is a daily activity for hoof trimmers, veterinarians, and livestock producers, there is surprisingly little information in the peer-reviewed literature on which to base strong evidence-based conclusions. As a consequence, many treatment modalities used are empirical and, in some cases, may be counterproductive to rapid lesion healing. Furthermore, many of these empirical treatment modalities fail to fully consider the underlying pathogenesis of the disease process and the implications that it has on lesion healing. For example, sole ulcers are largely a consequence of metabolic disorders and mechanical overloading. Therapeutic interventions that fail to address the weight-bearing issues are unlikely to be successful. Likewise, white line disease is believed to be predisposed by rumen acidosis and laminitis, and interventions need to include in them appropriate measures to prevent further cases through nutritional management. The goal of this review paper is to review the pathogenesis of claw lesions in the context of the published literature and allow the reader to arrive at rational treatment interventions based on the best available information. The use of an orthopedic block applied to the healthy claw of a lame foot, judicious use of bandage or wrap, careful selection of parenteral or topical therapy, and a treatment protocol to manage pain and promote recovery are key components of responsible management of lameness disorders in cattle.Keywords: lameness

    This paper is devoted to the wave structure of a flow at its near- and supersonic velocities in a flat turbine cascade of profiles in the zone of phase transitions. The main task was investigation of the mechanics of interaction of the condensation jump with the adiabatic jumps of packing in a change of the initial condition of the flow. The obtained results are necessary for verification of the calculation models of the moisture-steam flow in the elements of lotic parts of the steam turbines. The experimental tests were made on a stand of the wet steam contour (WSC-2) in the Moscow Power Engineering Institute (MPEI, National Research University) at various initial states of steam in a wide range of Mach numbers. In the investigation of the wave structure, use was made of an instrument based on the Schlieren-method principle. The amplitude-frequency characteristics of the flow was found by measurement of static pressure pulsations by means of the piezo resistive sensors established on a bandage plate along the bevel cut of the cascade. It is shown that appearance of phase transitions in the bevel cut of the nozzle turbine cascade leads to a change in the wave structure of the flow. In case of condensation jump, the system of adiabatic jumps in the bevel cut of the cascade becomes nonstationary, and the amplitude-frequency characteristics of static pressure pulsations are restructured. In this, a change in the frequency pulsations of pressure and amplitude takes place. It is noted that, at near-sonic speeds of the flow and the state of saturation at the input, the low-frequency pulsations of static pressure appear that lead to periodic disappearance of the condensation jump and of the adiabatic jump. As a result, in this mode, the flow discharge variations take place.

    Purpose: Phantom surrogates were developed to allow multimodal [computed tomography (CT), magnetic resonance imaging (MRI), and teletherapy] and anthropomorphic tissue simulation as well as materials and methods to construct deformable organ shapes and anthropomorphic bone models. Methods: Agarose gels of variable concentrations and loadings were investigated to simulate various soft tissue types. Oils, fats, and Vaseline were investigated as surrogates for adipose tissue and bone marrow. Anthropomorphic shapes of bone and organs were realized using 3D-printing techniques based on segmentations of patient CT-scans. All materials were characterized in dual energy CT and MRI to adapt CT numbers, electron density, effective atomic number, as well as T1- and T2-relaxation times to patient and literature values. Results: Soft tissue simulation could be achieved with agarose gels in combination with a gadolinium-based contrast agent and NaF to simulate muscle, prostate, and tumor tissues. Vegetable oils were shown to be a good representation for adipose tissue in all modalities. Inner bone was realized using a mixture of Vaseline and K{sub 2}HPO{sub 4}, resulting in both a fatty bone marrow signal in MRI and inhomogeneous areas of low and high attenuation in CT. The high attenuation of outer bone was additionally adapted by applying gypsum bandages to the 3D-printed hollow bone case with values up to 1200 HU. Deformable hollow organs were manufactured using silicone. Signal loss in the MR images based on the conductivity of the gels needs to be further investigated. Conclusions: The presented surrogates and techniques allow the customized construction of multimodality, anthropomorphic, and deformable phantoms as exemplarily shown for a pelvic phantom, which is intended to study adaptive treatment scenarios in MR-guided radiation therapy.

    To review the signalment, clinical characteristics, and outcome of horses with nonhealing corneal ulcers treated with diamond burr debridement (DBD); and to evaluate the role of ulcer duration, size and location, and bandage contact lens (BCL) placement on healing. From January 2012-April 2013, 60 horses were diagnosed with ulcers classified as nonhealing based on the presence of raised epithelial margins and duration of at least 7 days. Retrospective record review. Average age of included horses was 14.68 years, SD 8.17 years. There were three times as many males (45) as females (15), (χ12 = 15, P = 0.001). Forty-eight horses (80%) had nonhealing ulcers uncomplicated by associated corneal disease. In the remaining horses, associated corneal disease included esinophilic keratitis (10%), calcific band keratopathy (5%), endothelial decompensation (1.67%), habronemiasis(1.67%), and lid suture abrasion (1.67%). Average corneal ulcer duration prior to diamond burr debridement (DBD) was 29.0 days (n = 56). Ulcers occurred most commonly in the axial cornea (41%). Fifty-five of 60 horses (92%) healed with DBD. Healing time, defined as time to epithelialization following DBD, averaged 15.5 days, SD 9.32 days, and was not correlated with patient age or ulcer duration, location, or size prior to or following DBD. Healing time was significantly longer for eyes in which a BCL had been placed (n = 28, 19.0 days) than for eyes without a BCL (n = 32, 12.9 days), F(1,58) = 5.543, P = 0.02. DBD was considered a failure for five horses (8%). DBD may be an effective treatment for nonhealing corneal ulcers in horses. © 2014 American College of Veterinary Ophthalmologists.

    Full Text Available Breast-cancer-related lymphedema is a significant morbidity mostly observed following primary treatments for breast cancer (surgery, radiation, and chemotherapy (1. Multiple complications might accompany lymphedema including cosmetic deformity, psychological disorders, consistent pain, and consequently decreased quality of life. Treatment  mostly focuses on reducing edema and its subsequent pain; however, no definite treatment has been hitherto introduced (2. Surgical approaches in the management of lymphedema are efficient including physiologic methods (e.g. flap interposition, lymph transfer, and lymphatic bypass and reductive techniques (e.g. liposuction (3. While the former mostly targets at reducing lymphedema through restoring lymphatic drainage, the latter aims at removing fibrofatty tissues which contribute to lymph stasis. Microsurgical variation of lymphatic bypass has gained popularity, in which the accumulated lymph in the lymphedematous limb is redirected. Non-surgical approaches are also practiced in most cases. Comprehensive decongestive therapy, consisting of skin care, exercise, special bandaging and massage, is the most frequently used non-surgical approach efficacy of which could be enhanced in combination with self-management strategies (4. Recently newer techniques have been introduced to tackle lymphedema and its associated pain. Manual lymph drainage, stellate ganglion block, acupuncture, deep oscillation, and pneumatic compression have been efficiently used in several studies. Moreover, significant short-term progress has been reported following other modalities such as low-level laser therapy (5. The complexity of breast-cancer-related lymphedema and its complications necessitates a multidisciplinary approach with the primary goal of easing the burden of the disease on the breast cancer patients. In addition, developing special guidelines encompassing these multidisciplinary approaches and providing educational and

    This paper reports the characteristics and local management of 826 acute wounds identified during an audit across all health care providers serving the population of Bradford, UK. Of the wounds encountered 303 were traumatic wounds and 237 primary closures with smaller numbers of other acute wound types. Of the 303 traumatic wounds 174 occurred in women (57.4%). Men predominated in the under 45s (65M:26F), this being largely accounted for by hand and finger trauma (n = 62) particularly in patients of working age (M32:F12). Women predominated in the over 65s (50M:130F), this being largely accounted for by lower limb traumatic wounds (M24:F91), the majority of these being in patients 65 and over (M14:F82). In this sub-group of 96 patients 25 had wounds of 6 weeks or longer duration, only 3 had undergone Doppler assessment and only 2 received compression bandaging. Typically these wounds were of recent origin and small in size (under 1 week and less than 5 cm2 in surface area) however exceptions occurred where 10 people had wounds over 25 cm2 in area while 3 wounds had been present for over 5 years. 101 (12.2%) of the encountered wounds were considered to be infected although the practice of wound swabbing in the presence of presumed infection seemed inadequate with 37.6% of all infected acute wounds not being swabbed while 97 non-infected wounds were swabbed. Where wounds were swabbed 4.5% were found to be MRSA positive. Across all acute wound types (with the sole exception of primary closures) antimicrobial wound dressings were the most prevalent form of dressing and covered 56 (55.4%) of all infected wounds.

    Aim: Veterinarians have frequently to deal with wounds to the skin, subcutis, and underlying muscle. The aim was to explore the application of hyaluronic acid (HA)-containing dressing on open skin wounds in dogs. The progress of healing was assessed by wound area reduction and two scoring scales applied in human medicine. Materials and Methods: Ten client-owned dogs with 12 cutaneous open wounds healed by the second intention were included. All wounds were treated using available in commerce HA-containing wound dressing from admission to complete re-epithelialization. At every clinical examination, wound area and scale scoring assessments were performed. Results: After debridement, an increased wound size was obtained while an improvement was determined by both grading systems. The median numbers of return to the clinic for bandage change were 5 times. The median time to complete wound healing was 34.5 days. The mean wound area at day 7, 14, 21, and 28 were, respectively, 90.4%, 47.7%, 22.4%, and 14.8% of the original size (for linear measurement) and 95.5%, 54.4%, 23.10%, and 14.8% of the original size (for software measurement). Regarding wound healing assessment tools, the agreement between two operators was considered high for both scales. Conclusions: HA-containing dressing may be a possible wound treatment for cutaneous open wounds in dogs. The assessment of wound quality using scale scoring system could be useful especially in the 1st week and to direct clinical decision-making process. PMID:27047026

    To compare the gross and histological effects of intravenous regional limb perfusion (IVRLP) using amikacin sulfate on second intention healing of distal limb wounds in adult horses with healing in untreated wounds. In vivo experimental study. Adult horses (n = 7). Two full thickness wounds (2.5 × 2.5 cm) were created aseptically on the dorsal aspect of each metacarpus and maintained under sterile bandages. One forelimb was randomly selected from each horse for IVRLP on days 2, 3, and 4 post-wounding. Sequential biopsies were taken from 1 wound on each limb to evaluate the histological effects of IVRLP. Photographs were obtained of nonbiopsied wounds from days 2 to 62 for gross assessment and wound measurement. Wound size and contraction, healing rate during and immediately after IVRLP treatment, total healing rate, and histological scores for edema, hemorrhage, inflammatory infiltrate, and fibrovascular proliferation were compared. No differences were observed between groups for wound size, wound contraction, healing rates during or after IVRLP treatment periods, or total healing rate. Wound size over time was larger in the IVRLP group compared with the control group; however, this difference did not reach statistical significance. Mononuclear cell infiltration was greater in the IVRLP group compared with controls. No differences were observed for other histological variables. All wounds healed without the formation of exuberant granulation tissue. Treatment for 3 consecutive days with IVRLP using amikacin sulfate did not negatively affect surgical wounds healing by second intention in the distal limb of horses. © Copyright 2015 by The American College of Veterinary Surgeons.

    Cervical Cancer (CC) has become a public health concern of alarming proportions in many developing countries such as Mexico, particularly in low income sectors and marginalized regions. As such, an early detection is a key medical factor in improving not only their population's quality of life but also its life expectancy. Interestingly, there has been an increase in the number of reports describing successful attempts at detecting cancer cells in human tissues or fluids using trained (sniffer) dogs. The great odor detection threshold exhibited by dogs is not unheard of. However, this represented a potential opportunity to develop an affordable, accessible, and non-invasive method for detection of CC. Using clicker training, a male beagle was trained to recognize CC odor. During training, fresh CC biopsies were used as a reference point. Other samples used included cervical smears on glass slides and medical surgical bandages used as intimate sanitary pads by CC patients. A double-blind procedure was exercised when testing the beagle's ability to discriminate CC from control samples. The beagle was proven able to detect CC-specific volatile organic compounds (VOC) contained in both fresh cervical smear samples and adsorbent material samples. Beagle's success rate at detecting and discriminating CC and non-CC odors, as indicated by specificity and sensitivity values recorded during the experiment, stood at an overall high (>90%). CC-related VOC in adsorbent materials were detectable after only eight hours of use by CC patients. Present data suggests different applications for VOC from the uterine cervix to be used in the detection and diagnosis of CC. Furthermore, data supports the use of trained dogs as a viable, affordable, non-invasive and, therefore, highly relevant alternative method for detection of CC lesions. Additional benefits of this method include its quick turnaround time and ease of use while remaining highly accurate and robust.

    Lymphedema is a prevalent long-term effect of breast cancer treatment that is associated with reduced quality of life. More recent observational data suggest that the addition of night-time compression to day-time use of a compression garment results in better long-term control of arm lymphedema. The primary objectives of the randomized controlled phase of the trial are to determine the efficacy of night-time compression on arm lymphedema volume maintenance and quality of life in breast cancer survivors who have completed intensive reduction treatment for their lymphedema. The study will be a parallel 3-arm, multi-centre randomized fast-track trial. A total of 120 women with breast cancer related lymphedema will be recruited from 3 centres in Canada and randomized to group 1: Day-time compression garment alone or Group 2: Day-time compression garment + night-time compression bandaging or Group 3: Day-time compression garment + use of a night-time compression system garment. The duration of the primary intervention period will be 12 weeks. The follow-up period after the intervention (weeks 13 to 24) will follow a longitudinal observational design. The primary outcome variables: differences from baseline to week 12 in arm volume and quality of life (Lymphoedema Functioning, Disability and Health Questionnaire: Lymph-ICF). Secondary outcomes include bioimpedance analysis, sleep disturbance and self-efficacy. All measurements are standardized and will be performed prior to randomization, and at weeks 6, 12, 18 and 24. The use of night-time compression as a self-management strategy for chronic breast cancer related lymphedema is seen as an innovative approach to improve long-term control over the condition. This trial aims to advance the knowledge on self-management strategies for lymphedema

    The maintenance of an aseptic environment for chronic wounds is one of the most challenging tasks in the wound-healing process. Furthermore, the emergence of antibiotic-resistant bacterial strains is on the rise, rendering conventional treatments less effective. A new antibacterial material consisting of a polyurethane Tecophilic(™) nanofibre textile (NT) that was prepared by electrospinning and doped by a tetraphenylporphyrin (TPP) photosensitizer activated by visible light was tested for use in wound beds and bandages. In vitro experiments were performed to assess the antibacterial activity of the textile against three bacterial strains. Furthermore, the new textile was tested in 162 patients with chronic leg ulcers. A complete inhibition of in vitro growth of the three tested bacterial strains was observed on the surface of NTs that had been illuminated with visible light and was clinically demonstrated in 89 patients with leg ulcers. The application of the textiles resulted in a 35% decrease in wound size, as assessed via computer-aided wound tracing. Wound-related pain, which was estimated using a visual analogue scale, was reduced by 71%. The results of this trial reveal that the photoinactivation of bacteria through the photosensitized generation of short-lived, highly reactive singlet oxygen O(2) ((1) Δ(g) ) results in relatively superficial antibacterial effects in comparison with standard antiseptic treatment options. Thus, such treatment does not interfere with the normal healing process. This method therefore represents a suitable alternative to the use of topical antibiotics and antiseptics and demonstrates potentially broad applications in medicine. © 2012 John Wiley & Sons A/S.

  6. Safety and efficacy of the Perclose suture-mediated closure device following carotid artery stenting under clopidogrel platelet blockade

    The aim of this study was evaluation of a closure device (Perclose, Menlo Park, Calif.) for closure of the femoral artery access site in patients undergoing aggressive anticoagulation and platelet blockade after carotid stenting. Fifty-five patients who received clopidogrel in addition to aspirin and heparin as medication for carotid stenting were included for suture of the femoral access site after using 7- or 8-F guide catheters. The technical success, the time for suture, the clotting parameters, and complications were examined. Follow-up investigations, including ultrasound and clinical examinations, were performed. The groin was checked for possible hematoma, pseudoaneurysm, arteriovenous fistula, and local infection. Technical success was obtained in 51 of 54 patients (94%) after a mean procedure time of 6 min (range 5-10 min). The suture device was not used in one patient (2%) for anatomical reasons and failed to obtain hemostasis in 3 of 54 (6%) patients. In 4 of 54 patients (7%) bleeding was observed at the punctured site 4-6 h after intervention which was treated by a compression bandage. The mean dedicated activated clotting time was 137 s (range 29-287 s) before intervention and 349 s (150-958 s) just before deploying the Perclose device. During follow-up after 2 days (range 2-6 days) and 6 months no further complications of the puncture site were observed except for two large groin hematomas. No major complications occurred. Closure of the femoral access site after carotid stenting using a Perclose closure device is safe and effective even in patients receiving an aggressive anticoagulation and antiplatelet therapy.

    Most patients with acute hydrocephalus have ventriculomegaly and high intracranial pressure (ICP). However, there is a subset of patients who are symptomatic with acute ventriculomegaly and inappropriately low ICP. Two patient groups were defined. Each patient presented with clinical deterioration that included a significant decrease in level of consciousness with new and significant ventriculomegaly. Patients in group 1 (n = 10) were managed without endoscopic third ventriculostomy (ETV). Group 2 was a series of patients (n = 10) managed with ETV. Treatment for both groups involved insertion of an external ventricular drain (EVD) with ICP <5 cmH(2)O. Further treatment consisted of either neck wrapping with a tensor bandage and/or lowering the EVD to negative levels to facilitate drainage of cerebrospinal fluid (CSF), which resulted in clinical improvement and resolution of ventriculomegaly. All 20 patients had anatomical obstruction to CSF flow into the subarachnoid space (SAS) confirmed by magnetic resonance imaging (MRI) with cine MRI studies. Group 1 patients were treated until shunt revision/insertion was possible (n = 7), ICP normalized, and the EVD could be removed (n = 2), or death (n = 1) occurred. Patients in group 2 all underwent ETV, and ICP patterns normalized in all. Group 2 patients were managed with an EVD until shunt revision/insertion was required (n = 2), ICP normalized and the EVD could be removed (n = 7), or death (n = 1) occurred. The syndrome of inappropriately low-pressure acute hydrocephalus (SILPAH) is an important entity in both children and adults. A possible hypothesis invokes loss of an effective SAS. ETV reestablishes communication between the SAS and ventricles, producing a rapid return of normal ICP dynamics and a significant decrease in the number of shunt-dependent patients.

    To describe the complications, short- and long-term outcomes, and owner satisfaction for dogs treated with pancarpal arthrodesis (PCA) using the 2.7/3.5 mm locking and dynamic compression plate (DCP) hybrid pancarpal arthrodesis plate (hybrid DCP [HDCP]) without rigid coaptation in the postoperative period. Retrospective case series. Dogs with carpal injuries requiring PCA (n=15). Records (May 2007-October 2013) of dogs that had PCA using 3.5/2.7 mm HDCP (1 or 2 plates) and a Robert-Jones bandage were reviewed to determine intra- and post-operative complications and overall limb function. Follow-up was obtained by clinical evaluation at our institution and telephone interview of owners. Fourteen dogs had PCA stabilized with a single HDCP and 1 giant breed dog had PCA stabilized with 2 HDCP on the dorsal aspect of the carpus secured onto the 3rd and 4th metacarpal bones. Two dogs presented with bilateral injuries. Thirteen owners (87%) judged the results of surgery as excellent and 2 (13%) judged the results of surgery as good. Minor complications (4 limbs; 23%) were occasional episodes of mild lameness in 3 dogs and 3 episodes of discharging sinus tracts in a single dog. Major complications (3 limbs; 17%) included 1 surgical site infection and implant failure in a 43 kg dog with an active leishmaniasis infection and a concurrent bilateral sacro-iliac luxation. Two dogs developed episodes of discharging sinus tract and pain over the most distal screw that eventually necessitated plate removal. PCA without rigid coaptation can successfully be performed using the HDCP. © Copyright 2016 by The American College of Veterinary Surgeons.

    Critically ill patients are at high risk of developing pressure ulcers (PU), with the sacrum and heels being highly susceptible to pressure injuries. The objective of our study was to evaluate the clinical effectiveness of a new multi-layer, self-adhesive soft silicone foam heel dressing to prevent PU development in trauma and critically ill patients in the intensive care unit (ICU). A cohort of critically ill patients were enrolled at the Royal Melbourne Hospital. Each patient had the multi-layer soft silicone foam dressing applied to each heel on admission to the emergency department. The dressings were retained with a tubular bandage for the duration of the patients' stay in the ICU. The skin under the dressings was examined daily and the dressings were replaced every three days. The comparator for our cohort study was the control group from the recently completed Border Trial. Of the 191 patients in the initial cohort, excluding deaths, loss to follow-up and transfers to another ward, 150 patients were included in the final analysis. There was no difference in key demographic or physiological variables between the cohorts, apart from a longer ICU length of stay for our current cohort. No PUs developed in any of our intervention cohort patients compared with 14 patients in the control cohort (n=152; psilicone foam dressing under investigation was clinically effective in reducing ICU-acquired heel PUs. The findings also support previous research on the clinical effectiveness of multi-layer soft silicone foam dressings for PU prevention in the ICU.

    To evaluate the effect of intramuscular administration of recombinant equine growth hormone on healing of full thickness skin wounds on equine limbs. Experimental. Nine Standardbred horses. In study 1, standardized full thickness skin wounds (2.5 x 2.5 cm) were made over the dorsomedial aspect of the mid-cannon bone of 1 forelimb and 1 hindlimb in 9 horses. Wounds were bandaged without treatment (control subjects) and videorecorded twice weekly until healed. Then, in study 2, similar wounds were created on the opposite limbs; 6 horses were administered intramuscular recombinant equine growth hormone (10 microg/kg daily for 7 days, then 20 microg/kg daily for 49 days), and 3 horses (control subjects) were administered equivalent volumes of sterile water. Wounds were videorecorded twice weekly until healed. Wound healing variables were measured from the videorecordings using a computer software package and analyzed as a randomized complete block design factorial analysis of variance; significance was set at P wounds in study 1 and the control wounds in study 2. In recombinant equine growth hormone-treated horses, wounds retracted more during treatment and contracted faster after treatment stopped when compared with wounds from untreated horses. No other treatment effects were detected. Recombinant equine growth hormone seemingly increases wound retraction. After treatment ceases, wound contraction increases. Intramuscular administration of recombinant equine growth hormone (10 microg/kg daily for 7 days, then 20 microg/kg daily for 49 days) does not appear to have any beneficial clinical effect on healing of equine limb wounds.

    The purpose of the study - assessment of purulent-inflammatory processes etiologic factors and determination of microbial agents' in forms of plankton and biofilms sensitivity to antibiotics. Clinical microbial strains isolated from patients with purulent-inflammatory processes were the subject of the study. The study material comprised of wound tissue, pus, bandage and suture, catheters and drainage devices. Sensitivity of isolates to antimicrobial preparations with various mechanism of activity on the microbial cells was studied with the help of micro-test system. Formation of biofilms was studied with the help of definition of bacteria strains ability to adhesion to the surface of polystyrene flatbeds. It was revealed that one of the leading factors of purulent-inflammatory process development is S.aureus, which disseminated in 36,5% of cases; E.coli disseminated in 17,3% of cases. Among the agents of purulent-inflammatory processes the specific gravity attributed to: Proteus spp. - 14,6%, S.рyogenes - 12,8%, P.aeruginosa - 6,9%, K.pneumoniae - 6,7%. It was revealed that all isolates formed dense biofilms. It was demonstrated that most isolates in plankton form were sensitive to Novapime, Cefepime, Gatifloxacin, Imipenem; sensitive strains were registered in a smaller quantity to Gentamicin, Clindamycin and Doxycycline. In terms of sensitivity of isolates in the form of biofilm to antibacterial preparations it was revealed that most isolates were polyresistant to them. Thus, the study of the sensitivity of allotted microbial strains to antimicrobial preparations demonstrated, that there were strains among cultures with multiple resistances which was the consequence of a wide and not always effective use of antimicrobial preparations.

    Percutaneous transverse aponeurotomy of the cord by using a hypodermic needle as a scalpel blade in order to improve function of the hand. Symptomatic flexion contracture with positive table top test caused by a single, palpable cord within the palm (primarily Tubiana stages I and II). Multiple, infiltrating or broad-based cords within the palm; irritated skin conditions; exclusive digital cord localization; recurrence after aponeurectomy; previous surgical intervention at the site of interest, digital nerve lesions; lack of patient compliance. Pinpoint surface anesthesia is obtained by injecting each portal area subdermally with 0.1 ml of local anesthetic. These applications start from distally to proximally within the palm while the most distal injection site is located proximal to the distal palm crease. Then the needle tip is introduced perpendicular to the cord. Sawing movements through the cord are performed transversely. While passively extending the contracted finger, the cord is held under tension which guarantees safe cutting. Patients are encouraged to report immediate pain sensation or numbness in order to prevent injuries to neurovascular structures and active finger flexion excludes tendon lesions during the procedure. Introducing the needle tip may be performed at several sites along the cord, if necessary, from distal to proximal at least 5 mm apart with prior pinpoint surface anesthesia. Finally, cautious passive stretching may be done after each release. Bandaging allowing immediate motion; application of a hand-based extension splint-glove during the night for 3-6 months. Recurrence rate was 53% in 15 retrospectively examined patients after a mean interval of 40 months postoperatively.

    A basic technical outline is given of the 1000 MW turbogenerator developed and manufactured by the SKODA Plzen Electrical Engineering Works for the new Czechoslovak nuclear power plants. The basic parameters of the machine are the following: apparent output 1111 MVA, active power 1000 MW, power factor 0.9, stator voltage 24 kV (±5 %), stator current 26.7 kA, frequency 50 Hz (±2.5 %), speed 3000 rpm, hydrogen pressure (abs.) 600 kPa, relative short-circuit current 0.4, efficiency 98.75 %, insulation F and thermal exploitation B. In order to respect the dimensions of the turbogenerator and the action of dynamic forces upon the active and mechanical part of the machine, a brand new concept was chosen for the strengthening of the stator winding ends. The magnetic circuit of the stator uses low-loss stampings with oriented grain of Czechoslovak make, 0.35 mm thick and insulated by the insulation producer with ceramic insulation. The rotor was imported from France. Also imported are the hollow conductors of the stator and rotor, the insulation of the slotted part of the rotor and the non-magnetic bandages of the rotor winding. The insulation of the stator coils (RELANEX) is of Czechoslovak make. The equipment of the turbogenerator is briefly described including the excitation system and the systems of sealing oil, gas and cooling water of the stator winding. The technology of turbogenerator manufacture and its testing are also described. (Z.S.) 9 figs

    To evaluate the in vitro, extended drug reservoir function of human amniotic membrane (HAM) of different thicknesses impregnated with moxifloxacin. HAM buttons (12 mm) were soaked with freshly prepared 0.5% wt/vol topical moxifloxacin at different soaking time intervals: 3 hours (group I), 6 hours (group II), 12 hours (group III), 24 hours (group IV), and 48 hours (group V). They were then transferred into 1 mL of fresh simulated tear fluid (pH-7.4) and incubated at 37°C. The release kinetics of moxifloxacin was studied by analyzing the amount of drug in simulated tear fluid collected at different time intervals from each pretreated HAM for 3 weeks. In another experiment, thin and thick HAMs were selected based on weight and soaked with moxifloxacin for 24 hours, and the release kinetics was studied for 7 weeks. All samples were stored at -80°C until analysis by high-performance liquid chromatography. No significant difference was observed between different soaking times and the release of moxifloxacin. The cumulative amount of moxifloxacin released from thick HAM was found to be statistically significant compared with thin HAM (P < 0.05). Our in vitro data showed that the sustained release of moxifloxacin from HAM was achieved up to 7 weeks. The entrapment efficiency of moxifloxacin was significantly higher in thicker HAM than in thin HAM. Moxifloxacin-impregnated HAM application can be considered in bacterial keratitis to provide sustained drug delivery through a biological bandage system for up to a period of 7 weeks.

    Full Text Available Abstract Introduction Bilateral rectus femoris haematoma following a simultaneous strain of the quadriceps muscles is a very rare condition. Case presentation We report the case of a 21-year-old Greek Caucasian female rowing athlete who was injured on both thighs. She complained of pain and inability to walk. Physical examination revealed tenderness over the thighs and restriction of knee movement. The result of a roentgenogram was normal, and there was no evidence of fracture or patella displacement. Magnetic resonance imaging revealed haematoma formation in both the rectus femoris muscles. The diameters of the left and right haematomas within the muscles were 6 cm and 5 cm, respectively. Therapeutic approaches included compression bandages, ice application, rest, elevation, and administration of muscle relaxant drugs. Active stretching and isometric exercises were performed after three days. The patient was able to walk using crutches two days after the initiation of treatment. On the seventh day, she had regained her full ability to walk without crutches. Non-steroidal anti-inflammatory drugs were administered on the fifth day and continued for one week. Six weeks later, she had pain-free function and the result of magnetic resonance imaging was normal. She was able to resume her training programme and two weeks later, she returned to her previous sport activities and competitions. Conclusion There are references in the literature regarding the occurrence of unilateral quadriceps haematomas following strain and bilateral quadriceps tendon rupture in athletes. Simultaneous bilateral rectus femoris haematomas after a muscle strain is a rare condition. It must be diagnosed early. The three phases of treatment are rest, knee mobilization, and restoration of quadriceps function.

    Full Text Available The article represents an overview and analysis of trenchless technologies used to provide for the leak resistance and strength of dilapidated sections of pipelines made of ceramics, cast iron, asbestos cement and other materials. Sectional pipeline repair technologies, considered by the authors, include those for the repair of loose joints of straight sections of pipelines and loose joints in the points of connection to secondary pipelines. Technologies analyzed by the authors also include those applied for the restoration of pipe shell cracks. Organic resins and bandages are to be used as repair materials.Besides, the authors provide detailed descriptions of the composition and properties of pumping resins injected into pipe cracks to restore the structural strength of pipelines and to assure their further reliable operation.Moreover, the authors assess the basic strengths of the bandage technology, including its low cost, low time consumption, and suitability to various types of pipeline damages (depressurization of joints, cracks, leaks, etc.. Besides, this method does not require any excavations, trenches, hoists or other machines.In particular, sections of underground pipelines, having diameters of 150 – 180 mm, may be repaired by specialized repair robots. Robots may be equipped with special-purpose devices, including cutter heads, bandage application heads, and color motion cameras. Besides, sectional repair of pipelines, having the diameter of up to 600 mm, may be performed using robots produced by Hachler Umwelttechnik, which are particularly efficient if the repair work is needed to be performed in the points of pipeline branching.The choice of specific pipeline repair methods and substantiation of their application are mainly driven by (1 the post-cleaning condition of a pipeline, (2 the findings of the telediagnostics, (3 options for arrangement and use of specialized machinery on location, and (4 feasibility of the pipeline

    difference in RV myocardial water content between the study groups and the Control Group. CONCLUSIONS: Adjustable pulmonary artery bandages permit rapid RV hypertrophy in both groups. Nevertheless, it is more efficient in the Intermittent Group. This study suggests that preparation of the pulmonary ventricle with intermittent systolic overload might provide better results for the 2-stage arterial switch operation.

    Full Text Available Background: Textile products commonly used in surgery (e.g., sponges or gauze have been known to cause complications after spinal surgery. Associated complications usually arise months or even years after the primary surgery. In case of spine surgery, these bodies are often detected during neuroradiological evaluations to investigate reported back pain; however, this complication often remains asymptomatic. Aims: The research is intended to increase awareness among both spinal surgeons and neuroradiologists of this potential complication. Study Design: Retrospective study. Methods: This study is a retrospective case series of three patients with retained surgical textile products who had been misdiagnosed with spinal tumour. The medical records of the patients were reviewed and demographic data, clinical aspects, initial diagnosis, surgical procedures, time interval between previous operation and onset of symptoms, laboratory findings, radiological findings, treatment, and outcome were analysed. Results: The three patients included two women and one man aged between 64 and 67 years. All patients had a previous surgery for lumbar disc herniation. The time from the previous surgical procedures to presentation ranged from 3 to 17 years. All patients presented with non-specific lower back pain and/or radiculopathy without clinical findings of infection. Laboratory parameters were otherwise normal. All three cases had been misdiagnosed as a spinal tumor based on magnetic resonance imaging findings. During new surgical procedures, gauze bandages, i.e., surgical textiles left during a previous operation, were found. Conclusion: Textiloma is an important and rarely mentioned potential neurosurgical complication that may remain asymptomatic for years. They are more common in obese patients, after emergency surgery, and with unplanned changes in surgical procedure such as bleeding and unintended neurosurgical complications. Neuroradiological findings are

Several therapeutic procedures including an anterior chamber washout, two pars plana vitrectomies, explantation of the posterior chamber intraocular lens and capsular bag, and multiple intravitreal antimicrobial injections, were performed to which he has ultimately responded favorably, with no signs of infection to date and stable visual acuity. The causative organism of his recurrent infections was initially identified as Mycobacterium abscessus through biochemical testing and 16S ribosomal ribonucleic acid gene sequencing; however, repeat polymerase chain reaction (PCR and sequencing of the 65 kDa heat shock protein (hsp65 gene for experimental purposes confirmed the accurate identification of the organism to be Mycobacterium chelonae. Given the greater reliability of PCR and sequencing of the hsp65 gene over traditional biochemical tests and culture techniques, M. chelonae was likely the
