...Vacuum Assisted Closure Therapy (VAC) Catherine van der Hoeven Capone Wilmington University Abstract Vacuum Assisted Closure Therapy (VAC) is a system for applying negative pressure to wounds, which is claimed to accelerate healing of chronic wounds. A foam sponge is placed into the wound, than the site is sealed with an adhesive drape, and negative pressure is applied to the wound for 22-24 hours daily. VAC decreases tissue edema and improves local circulation; it also removes the debris from the wound surface. The average cost, including the materials and nursing care ranges from $400-$500 per patient weekly. This technique has been used increasingly over the past decade for acute and chronic wounds, and studies have demonstrated improved wound healing. Its use has been extended to other types of wounds, such as surgical wounds from abdominal, chest and cardiac (heart) surgical procedures. Currently VAC can be used on all types of wounds: acute, subacute or chronic. Introduction Diabetes is becoming a common problem in most of the countries all over the world. About 1.8 million people are affected by diabetes and with rapidly increasing diabetic patients the count is estimated to go up to 2.7 million in next 25 years (Speak K, 2007). Diabetic foot complications are more frequent in males individuals aged over 60 years. The life expectancy of the diabetic patients has increased due different treatments, which in turn increases the number of complications as the...

...treat burns. Doctors have learnt that in case of minor burns, potato peel bandages work better than conventional dressing. Dr.P.V.Naryanan, a plastic surgeon of Jubilee Mission Medical College, in Thrissur, Kerala, told this correspondent The hospital realized the use of potato peel when renowned plastic surgeon of Mumbai, Dr M.H. Keswani, came visiting. He had been experimenting with potato peels for years. Dr.Narayanan said,”Dr.Keswani told us he started thinking about it after a friend said innocuously how similar dried potato peel was to stored skin used by plastic surgeons. He then realized potato peel did not desiccate quickly. Burns patients lose a lot of water through evaporation from the wound and potato peels prevent quick evaporation. Dr.Dattareya, an Indian-born doctor working in Holland, visited the jubilee Hospital and was amazed at the healing properties of potato peel. “He has published an article on it in a medical journal,” said Dr Narayanan. It’s been mentioned even in the ancient books. Potato peels provide moisture; they also have anti-bacterial properties that help in healing burn injuries. It’s the moisture that helps. The juices in a peel keep the wound moist. Perhaps this helps speed up the healing process. A dry wound is very painful and takes longer to heal.

...A venous leg ulcer is a chronic wound as it takes longer than six weeks to heal. It is caused by venous hypertension which is high blood pressure exerted in the veins of the legs which causes damage to the skin. Fluid can leak from the veins and pool under the skin causing swelling and thickening, this then leads to the skin breaking down to form an ulcer. Before a venous ulcer can be treated it is important to rule out peripheral arterial disease being the cause of the ulcer. Symptoms of peripheral arterial disease include pain in limb when exercising or walking, intermittent claudication, skin changes such as hair loss, cold to touch, oedema and ulceration. An arterial leg ulcer is caused by poor blood flow in the arteries and due to the current treatment of venous ulcers which is bandaging. This would reduce blood flow further and cause more damage making the ulcer worse. Having a history of varicose veins and a lack of mobility increases the chance of developing venous leg ulcers . According to SIGN (2010) when assessing a patient for the first time with a venous ulcer it is important to obtain their medical history in case of previous varicose veins and deep vein thrombosis as well as their mobility. Knowing these factors will contribute to managing the patients treatment, care and help with the rate of improvement. The framework model used to assess leg ulcers is the leg ulcer care pathway which is dived up into four stages 1. Patient...

...Department of Infection Control, Vilnius, Lithuania Accepted for publication: July 2015 S36 I British Journal of Nursing, 2015 (Tissue Viability Supplement), Vol 24, No 15 © 2015 MA Healthcare Ltd Abstract Background: Methicillin-resistant Staphylococcus aureus (MRSA) infections are an increasing problem worldwide with a high risk of severe illness and mortality in hospitalised patients. Patients with chronic wounds are at particular risk of developing MRSA infections. As octenidinebased products have shown promising success in decontamination in the past, the aim of the present study was to determine its efficacy, safety, and tolerability in decontaminating hospitalised MRSApositive patients. Methods: From 1 April 2011 until 9 November 2012, 36 patients were screened MRSA-positive at the Republican Vilnius University Hospital, Vilnius, Lithuania. At least three swab tests were performed for each patient to screen for MRSA, one from each nostril and one from the perineum. In patients with wounds, an additional swab was taken from the wound surface. In the affected patients octenidine-based products were used in one or two cycles of 7 days each. In addition, adverse events were recorded and the tolerability was assessed using a 4-point scale ranging from ‘very good’ to ‘poor’. Results: Complete decontamination was achieved in 24 patients (67%) following treatment with the octenidine-based products. None of the patients...

...Introduction 1. Wound A wound is defined as an injury or tear on the skin, which is caused by physical, chemical, mechanical, and thermal factors (Knight, 1996). The scientific definition of wound is a disruption of normal anatomic structure and function of the skin. On the basis of wound sites is classified into two types, such as open wound and closed wound. In other hand, on the basis of wound healing processes, there are divided into two types of wounds, such as acute and chronic wounds (Bryant and Nix, ). Acute wounds are caused by traumas. However, these wounds are usually healable within 8 to 12 weeks. Acute wounds can also be caused by exposure to extreme heat, irradiation and irritated with corrosive chemicals. Chronic wounds are...

...Review SKIN FUNCTION AND WOUND HEALING PHYSIOLOGY John Timmons is Clinical Manager, Wounds UK and Tissue Viabiliy Nurse, Aberdeen Regular evaluation and the setting of goals is essential to monitor the progress of the patient and their wound.To do this, is important to understand the physiology of the skin and the way normal wound healing progresses in order to plan and provide effective wound management. This article describes the structure and function of the skin and outlines the four normal phases of healing. Wound healing is an exciting and continually developing field, with new technologies and research playing a large part in improving the quality of patient care. The role of the nurse in wound care is all encompassing, stretching from the initial assessment of the wound and the patient, to making the correct decisions about treatment and beyond. Regular evaluation, and the setting of goals is essential to monitor the progress of the patient and the wound. To do this, a baseline knowledge of the functions and anatomy of the skin and wound healing physiology is required. Figure 1.

...ntroduction The Aloe vera plant has been known and used for centuries for its health, beauty, medicinal and skin care properties. The name Aloe vera derives from the Arabic word “Alloeh” meaning “shining bitter substance,” while “vera” in Latin means “true.” 2000 years ago, the Greek scientists regarded Aloe vera as the universal panacea. The Egyptians called Aloe “the plant of immortality.” Today, the Aloe vera plant has been used for various purposes in dermatology. History Aloe vera has been used for medicinal purposes in several cultures for millennia: Greece, Egypt, India, Mexico, Japan and China.1 Egyptian queens Nefertiti and Cleopatra used it as part of their regular beauty regimes. Alexander the Great, and Christopher Columbus used it to treat soldiers’ wounds. The first reference to Aloe vera in English was a translation by John Goodyew in A.D. 1655 of Dioscorides’ Medical treatise De Materia Medica.2 By the early 1800s, Aloe vera was in use as a laxative in the United States, but in the mid-1930s, a turning point occurred when it was successfully used to treat chronic and severe radiation dermatitis.2 Plant The botanical name of Aloe vera is Aloe barbadensis miller. It belongs to Asphodelaceae (Liliaceae) family, and is a shrubby or arborescent, perennial, xerophytic, succulent, pea- green color plant. It grows mainly in the dry regions of Africa, Asia, Europe and America. In India, it is found in Rajasthan, Andhra Pradesh, Gujarat, Maharashtra and Tamil...

...layperson’s comprehension. Nonetheless, because the use of HGF seems to be the direction some skin-care companies are taking, and because there is a large body of research showing its efficacy for wound healing (but not for wrinkles), it does deserve comment. HGFs make up a complex family of hormones that are produced by the body to control cell growth and cell division in skin, blood, bone, and nerve tissue. Most significantly, HGFs regulate the division and reproduction of cells, and they also can influence the growth rate of some cancers. HGFs occur naturally in the body, but they also are synthesized and used in medicine for a range of applications, including wound healing and immune-system stimulation. HGFs are chemical messengers that bind to receptor sites on the cell surface (receptor sites are places where cells communicate with a substance to let them know what or what not to do). HGFs must communicate with cells to instruct them to activate the production of new cells, or to instruct a cell to create new cells that have different functions. Another way to think of HGFs is that they are messengers designed to be received or “heard” by specific receptor sites or “ears” on the cell. HGFs, such as transforming growth factor (TGF, stimulates collagen production) or epidermal growth factor (EGF, stimulates skin-cell production), play a significant role in healing surgical wounds. The main task of HGFs is to cause cell division, which is helpful; however, at certain concentrations...

...The Effects of Zoonotic Diseases Case Study #13 April 17, 2011 Zoonosis refers to an infectious disease in animals that can be transmitted to people. An animal serves as the natural reservoir for such an infectious agent, ("MedTerms," 2001). Many zoonoses, which is simply the plural meaning of zoonosis, including viruses, bacteria, and parasites can be transmitted to humans by various routes. Some of these routes consist of animal bites, vectors (i.e., insects), and animal-to-human contact (i.e., inhalation of respiratory droplets or skin-to-skin contact), (Bauman 613-14) & ("Infectious Diseases," 2009). Most emerging infections that have occurred world wide are said to be a zoonotic disease. Many of these diseases are fatal or have the potential to be fatal if not treated quickly and properly identified. An example of a zoonosis case that has the potential to arise annually is listed below: Case Study#13 “You work in a small family practice in rural VA. A man in his early 50’s comes in with a complaint of intermittent fever (102-103°F) and headache for the past two weeks. The physician examines him and takes a history. The only clinical finding is a wound about the size of a quarter on his right thumb. Axillary lymph nodes are swollen and tender. The man says he cut himself while skinning a rabbit three days ago. On the basis of these observations the physician prescribes streptomycin and asks the man to call if his symptoms don’t...

...Jason’s Case Study Abstract Jason, a twenty six year old male, is seen in the urgent care clinic with a laceration to his arm. He cut his arm on roof sheeting while at work. While assessing the laceration on Jason’s arm, the nurse notices that he has a sunburn, freckles and moles on his skin. While Jason is still in the urgent care, the patient’s wife calls and asked if the medical staff would assess a mole on her husband. The nurse also educated Jason regarding sunburns, changes in freckles, moles, and lesions. His complexion, hair and eye color puts Jason at a higher risk for cancer and complications of being in the sun. The nurse also reminded Jason to make an appointment to have his family doctor check the laceration on his arm to make sure no infection or complications have developed. Jason’s Case Study After the nurse introduces herself to Jason, she gets his vital signs, height and weight. The nurse or the doctor per facility protocol should cleanse the wound to remove any dirt or debris from the laceration site. The nurse measures the laceration in length and width. The nurse checks the laceration for foreign bodies or debris in his arm. The doctor may order an x-ray of his arm to rule out any foreign bodies that may be in Jason’s arm. Saline gauze should be placed over the laceration site until the doctor comes into the examination room to see the patient. The nurse asks Jason if he has had a tetanus shot in the past five years. Jason should...
