How Do You Get Hepatitis A?
How Do You Get Hepatitis A? samer kareem 1,172 Views • 3 years ago

The hepatitis A virus, which causes the infection, usually is spread when a person ingests even tiny amounts of contaminated fecal matter. The hepatitis A virus infects liver cells and causes inflammation. The inflammation can impair liver function and cause other signs and symptoms of hepatitis A. Hepatitis A virus can be transmitted several ways, such as: Eating food handled by someone with the virus who doesn't thoroughly wash his or her hands after using the toilet Drinking contaminated water Eating raw shellfish from water polluted with sewage Being in close contact with a person who's infected — even if that person has no signs or symptoms Having sex with someone who has the virus

IV Cannulae - How To Reduce Spreading MRSA
IV Cannulae - How To Reduce Spreading MRSA DrHouse 14,262 Views • 3 years ago

Cannula are often introduced into blood vessels in 80% of patients in the hospital for treatment. This can be a daunting experience to patients and stressful to doctors as multiple attempts are used. This may result in introducing spreading MRSA, E Coli & Chlostredium living on your skin into blood and results in Invasive MRSA infection.

Skin is often not adequatly cleaned during subsequent atempts as doctors/nurses do not wait for 1 min after applying cleaning solution on the skin before they puncture your skin.

Multiple punctured sites allow CA-MRSA to enter blood stream resulting in bacteremia and death.

Our mission is to reduce spreading invasive CA-MRSA in the hospitals by developing alternative technique to introduce cannulae.

Medifix was created by doctors with a mission to reduce the threat of spreading antibiotic resustant bacteria to mankind.

How We See
How We See samer kareem 3,126 Views • 3 years ago

The eyes A close up of a young person's eyes. The eyes are responsible for four-fifths of all the information our brain receives. Here you can find out a bit more about how they work, common problems that affect vision and the work Sightsavers does to treat and prevent avoidable blindness. You can also find out more about the people whose lives have been changed thanks to donations from people like you. How do eyes work? (click image to see enlarged version or click here for text alternative) Graphic of an eye with information about its different parts The images we see are made up of light reflected from the objects we look at. This light enters the eye through the cornea. Because this part of the eye is curved, it bends the light, creating an upside down image on the retina (this is eventually put the right way up by the brain). The retina is a complex part of the eye, but only the very back of it is light sensitive. This part of the retina has roughly the area of a 10p coin, and is packed with photosensitive cells called rods and cones. Cones are the cells responsible for daylight vision. There are three kinds – each responding to a different wavelength of light: red, green and blue. The cones allow us to see images in colour and detail. Rods are responsible for night vision. They are sensitive to light but not to colour. In darkness, the cones do not function at all. How do we see an image? The lens focuses the image. It can do this because it is adjustable – using muscles to change shape and help us focus on objects at different distances. The automatic focusing of the lens is a reflex response and is not controlled by the brain. Once the image is clearly focused on the sensitive part of the retina, energy in the light that makes up that image creates an electrical signal. Nerve impulses can then carry information about that image to the brain through the optic nerve.

Heart Attacks
Heart Attacks samer kareem 5,640 Views • 3 years ago

A heart attack is a medical emergency. A heart attack usually occurs when a blood clot blocks blood flow to the heart. Without blood, tissue loses oxygen and dies. Symptoms include tightness or pain in the chest, neck, back, or arms, as well as fatigue, lightheadedness, abnormal heartbeat, and anxiety. Women are more likely to have atypical symptoms than men. Treatment ranges from lifestyle changes and cardiac rehabilitation to medications, stents, and bypass surgery.

Stab heart closing the pericardium,leaving a small window samer kareem 3,491 Views • 3 years ago

Pericardial window is used diagnostically and, more often, therapeutically for drainage of accumulated pericardial fluid (a condition that most often occurs after cardiac surgery but has many other possible causes). The pericardium envelops the heart like a cocoon; its cardiac filling can be impaired when this cavity fills with excess fluid. When the limited space between the noncompliant pericardium and heart is acutely filled with blood or fluid, cardiac compression and tamponade may result. Pericardial window in combination with systemic chemotherapy may also prevent accumulation of large fluid volumes in patients with neoplastic pericardial disease. [1, 2] Indications The following are indications for a pericardial window [6] : Symptomatic pericardial effusions Asymptomatic pericardial effusions that warrant a pericardial window for diagnosis Hemodynamically stable patients with an undiagnosed pericardial effusion (a thoracoscopic approach is ideal) Coexisting pericardial, pleural, or pulmonary pathology that requires diagnosis or therapy (a thoracoscopic approach is ideal) Known benign effusions that reaccumulate after aspiration Drainage of a purulent pericardial effusion Early fungal or tuberculous pericarditis in which resection of the pericardium is required to prevent future pericardial constriction Use as part of the mediastinal debridement, in patients with descending mediastinitis

What Is Phonemic Awareness, Reading Program For Kids, Phonics For Children, Teach Your Baby To Read---- http://children-learning-reading.good-info.co----- What is Phonemic Awareness, Phonemic Awareness is defined as the ability to identify, hear, and work with the smallest units of sound known as phonemes. It is NOT the same as phonological awareness, instead, it is a sub-category of phonological awareness. For example, phonemic awareness is narrow, and deals only with phonemes and manipulating the individual sounds of words - such as /c/, /a/, and /t/ are the individual sounds that make up to form the word "cat". Phonological awareness on the other hand, includes the phonemic awareness ability, and it also includes the ability to hear, identify, and manipulate larger units of sound such as rimes and onsets. Phonemic awareness can be taught very early on, and will play a critical role in helping children learn to read and spell. While it's not set in stone on when a child can learn to read, however, I do believe that a child that can speak is a child that can learn to read. Children as young as two years old can learn to read by developing phonemic awareness, and they can learn to read fluently. Please see a video of a 2 year old (2yr11months) reading below. Below are several of the most common phonemic awareness skills that are often practiced with students and young children: Phonemic identity - being able to recognize common sounds in different words such as /p/ is the common sound for "pat", "pick", and "play". Phonemic isolation - being able to recognize the individual sounds of words such as /c/ is the beginning sound of "cat" and /t/ is the ending sound of "cat". Phoneme substitution - being able to change one word to another by substituting one phoneme. For example changing the /t/ in "cat" to /p/ now makes "cap". Word Segmenting - the parent says the word "lap", and the child says the individual sounds: /l/, /a/, and /p/. Oral blending - the parent says the individual sounds such as /r/, /e/, and /d/, and the child forms the word from the sounds to say "red". Studies have found that phonemic awareness is the best predictor of reading success in young children. Research has also found that children with a high level of phonemic awareness progress with high reading and spelling achievements; however, some children with low phonemic awareness experience difficulties in learning to read and spell. Therefore, it is important for parents to help their young children develop good phonemic awareness. Being able to oral blend and segment words helps children to read and spell. According to the National Reading Panel, oral blending helps children develop reading skills where printed letters are turned into sounds which combine to form words. Additionally, word segmenting helps children breakdown words into their individual sounds (phonemes), and helps children learn to spell unfamiliar words. As a young child begins to develop and master phonemic awareness skills, they will discover an entirely new world in print and reading. You will open up their world to a whole new dimension of fun and silliness. They will be able to read books that they enjoy, develop a better understanding of the world around them through printed materials, and have a whole lot of fun by making up new nonsense words through phonemic substitutions. For example, we taught our daughter to read at a young age - when she was a little over 2 and a half years old. Before she turned three, she would run around the house saying all types of silly words using phonemic substitution. One of her favorite was substituting the letter sound /d/ in "daddy" with the letter sound /n/. So, she would run around me in circles and repeatedly say "nanny, nanny, come do this" or "nanny, nanny, come play with me" etc... Of course, she only did this when she wanted to be silly and to make me laugh, at other times, she would of course properly refer to me as "daddy", and not "nanny". She is well aware of the differences between these words and is fully capable of using phonemic substitution to change any of the letters in the words to make other words.

Endoscopic Dacryocystorhinostomy
Endoscopic Dacryocystorhinostomy samer kareem 7,153 Views • 3 years ago

Dacryocystorhinostomy (DCR) is a procedure performed for the treatment of tearing (epiphora) due to blockage of the nasolacrimal duct. Tears originate in the lacrimal gland, located at the upper outer margin of the eye. As tears cross the eye with each blink, they are directed into small openings in the eyelids called puncta. From this point, tears travel through a pathway known as the canalicular system into the lacrimal sac. The lacrimal sac is located between the eye and the nose, and funnels tears into the nasal cavity through the nasolacrimal duct (Figure 1). As this is quite a long path for tears to travel, there can be many causes of excessive tearing. Blockage of the nasolacrimal duct is one common cause, and can be treated by creating a direct opening from the lacrimal sac into the nasal cavity in a procedure known as DCR. The evaluation and management of tearing may involve both an ophthalmologist and an otolaryngologist.

Rotator Cuff Injury
Rotator Cuff Injury samer kareem 1,866 Views • 3 years ago

The rotator cuff is a group of muscles and tendons that surround the shoulder joint, keeping the head of your upper arm bone firmly within the shallow socket of the shoulder. A rotator cuff injury can cause a dull ache in the shoulder, which often worsens when you try to sleep on the involved side. Rotator cuff injuries occur most often in people who repeatedly perform overhead motions in their jobs or sports. Examples include painters, carpenters, and people who play baseball or tennis. The risk of rotator cuff injury also increases with age. Many people recover from rotator cuff disease with physical therapy exercises that improve flexibility and strength of the muscles surrounding the shoulder joint. Sometimes, rotator cuff tears may occur as a result of a single injury. In those circumstances, medical care should be provided as soon as possible. Extensive rotator cuff tears may require surgical repair, transfer of alternative tendons or joint replacement.
