Ingrown hairs, normally known as Razor knocks, are hairs that have twisted around and developed once more into the skin as opposed to ascending from it. As indicated by the University of Alabama at Birmingham Health System, ingrown hairs or razor knocks seem most every now and again among individuals of the African American group or individuals who have wavy hair. An ingrown hair can deliver a raised, red knock that resembles a little pimple. Now and again, there may be discharge inside the knock

you are ready for the vision correction, it is very important that you choose your Lasik eye surgeon with great care and after due diligence. You should remember to choose a New York Lasik center that offers multiple options for vision correction surgeries. Also keep in mind that all patients are not benefitted by the Lasik procedure. Depending upon many factors you may require a different procedure. A center that is only offering you Lasik procedure may be tempted to brow beat you into going ahead

rays travel in a straight line inside of the two media, and bends at the boundary. To find out change of speed of light as it travels from the air into glass, we can use the Refractive Index formulae; which is a measure of how much the light slows down as it enters the dense medium (glass). The formulae is written as: Refractive Index: Speed in Air / Speed in a material Light travels at 3 x 10^8 ms^-1 in air while light travels 2 x 10^8

when light enters a more or less optically dense medium, which therefore has a different refractive index (measure of the velocity light can travel at in the medium compared to in a vacuum in which it can travel at 2.9 x 108ms-1). This causes the light’s speed to increase or decrease, which results in the rays bending towards or away from the normal, so the position of the image formed is dependent on the refractive indices of the two media. For refraction to occur, the light rays have to hit the boundary

cataracts are dealt with today is by cataract extraction and intra-ocular lens placement which is what we referred the patient for after her first visit. There are three main types of cataract surgeries that are used today. They are phacoemulsification, extracapsular extraction, and laser cataract surgery. In phacoemulsification, the surgeon makes a small incision near the limbus to insert an ultrasonic probe. This probe is pointed at the cataract and ultrasonic waves bust up the cataract. These

such as Creutzfeldt-Jakob disease, Alzheimer's disease, dementia, multiple sclerosis and motor neuron disease are contraindications to ocular tissue donation as well. Other contraindications include recipients of transplanted organs, prior ocular surgery and ocular diseases that are likely to compromise the graft outcome as inflammation and malignancy. Eye Bank Association of America. Medical Standards. http://www.restoresight.org. The donor tissue is inspected by slit-lamp biomicroscopy and the

ABSTRACT Managing trauma to anterior teeth in children is a challenge for dentists. It can be further complicated by the presence of a foreign body in the root canal which act as an additional nidus of infection. This foreign body is often diagnosed accidentally after radiographic evaluation. Thorough and careful clinical and radiographic assessments are required for complete retrieval of foreign body without much damage to the tooth structure. This paper presents a case series of two case reports

substantially. Many pathological conditions of ankle that have been treated with open surgery are now treated with arthroscopy. Arthroscopic surgery of ankle allows direct visualization of intra-articular structures. The increase use in arthroscopy is attributed to its speedy recovery, decreased morbidity and quicker rehabilitation. Gasparetto F. Arthroscopic approaches to the ankle joint The arthroscopic surgery begins by making two or three small openings called portals. Through these portals,

Introduction Organ transplantation is one of the greatest achievements in modern medicine. In 2015, more than 4000 lives were saved and improved by an organ transplant in the UK. However, not all of people waiting for a lifesaving transplant can benefit from transplantation because of the shortage of organ donation. British people have legitimate reasons to concern about their donor shortage as their country’s organ donor rate is much lower than many European nations although the UK is one of the

Despite our advances in medical technology, each year, thousands of people suffer and die due to organ failure. There are various causes to organ failure, either by physical damage, genetic mutation (exogenous factors: e.g. sunlight, radiation, smoking, etc..), and genetically inherited diseases. At this point in time, there are numerous of ways to solving organ failure, such as through the use of dialysis, pacemakers, drugs, etc… But in the end, the most sustainable way of potentially curing organ

The first description of the etiology and surgical approach to Hirschsprung 's disease was by Dr Ovar Swenson in 1948[1]. Swenson 's operation was difficult to carry out in early infancy also extensive dissection of the pelvis occasionally caused complications, therefore several methods including those proposed by Duhamel[2], Soave[3], and their modifications have been devised aiming at minimizing pelvic dissection, preserving the rectal wall and maintaining rectal sensation. Many problems, however

Bioprosthetic valves used in heart valve replacement generally offer functional properties that are more similar to those of native valves. Implantation of prosthetic cardiac valves to treat hemodynamically significant aortic or mitral valve disease has become increasingly common. Replacement of diseased valves with prosthetic heart valves reduces the morbidity and mortality associated with native valvular disease, but it comes at the expense of risking complications related to the implanted prosthetic

Anatomy and Physiology: In order to understand about cleft lip and palate we must know the complete anatomy and physiology of cleft i.e. we must know what is cleft? What is the normal and abnormal anatomy?, what are the factors that causing clefts? Etc. As the number of children’s with cleft lip and palate increasingly day by day that's why there is a critical need of effective and appropriate diagnosis and treatment of person's suffering from cleft lip and palate. 1. Hard palate: In simple words

“The greatness of a nation can be judged by the way its animals are treated,” a quote from Mahatma Gandhi. Animal testing has been around since ancient times with the Greek and Romans. Aristotle and Erasistratus were the first documented to perform experiments on animals between the years 384 and 258 BCE. Since the 1600’s, many people have debated on whether it is morally correct or wrong to test on animals. While testing on animals might help humans slightly, is it what we should do? First, humans

By Jonas Wilson, Ing. Med. Vascular Surgery The surgical branch dealing with disorders of the circulatory system, which includes arteries, veins and lymphatic vessels, is called vascular surgery. These specialists treat varying conditions, such as aneurysms and atherosclerosis. These are abnormal dilations in vessel walls and narrowing/ hardening of the arteries, respectively. Vascular surgeons are focused on fixing vessels in nearly all parts of the body with the exception of the brain and heart

Although small in size the spleen is a very busy organ. Despite the advances made in medicine there are some unknown aspects of the mysterious organ, but it is known to provide important services that benefit the body. There are several diseases and injuries that lead to what is called a splenectomy, the surgical removal of the spleen. A splenectomy is performed to diagnose and provide treatment to benign or malignant masses, torsion, rupture caused by some type of trauma or tumor, severe infection

BACKGROUND OF ENDOSCOPIC SINUS SURGERY. In the history of nose and sinus surgery, Sinus surgery has been performed in one or another forms for over 100 years. However Functional endoscopic sinus surgery has been practiced widely only in the last 2 decades.19 Sinus surgery emerged in Egypt where brain was removed through ethmoid sinuses by instruments as part of mummification process. In 18th century, maxillary sinus empyema was drained through the tooth socket or anterior wall of the maxillary sinus
