How does the brain work?
How does the brain work? samer kareem 1,402 Views • 2 years ago

The brain is the most complex organ in our body. It controls everything we do, from simple things such as breathing, to complex things such as co-ordinating our movements. The brain stores our memories, allows us to think and speak, and controls how we behave

NEURON ACTION POTENTIAL
NEURON ACTION POTENTIAL samer kareem 4,052 Views • 2 years ago

Your body has nerves that connect your brain to the rest of your organs and muscles, just like telephone wires connect homes all around the world. When you want your hand to move, your brain sends signals through your nerves to your hand telling the muscles to contract. But your nerves don’t just say “hand, move.” Instead your nerves send lots of electrical impulses (called action potentials) to different muscles in your hand, allowing you to move your hand with extreme precision.

TALUS FRACTURE
TALUS FRACTURE samer kareem 1,469 Views • 2 years ago

A talus fracture is a break in one of the bones that forms the ankle. This type of fracture often occurs during a high-energy event, such as a car collision or a high-velocity fall. Because the talus is important for ankle movement, a fracture often results in significant loss of motion and function. In addition, a talus fracture that does not heal properly can lead to serious complications, including chronic pain. For this reason, many talus fractures require surgery.

Mitral Valve Regurgitation Treatment
Mitral Valve Regurgitation Treatment samer kareem 1,252 Views • 2 years ago

A leaking mitral valve allows blood to flow in two directions during the contraction. Some blood flows from the ventricle through the aortic valve – as it should – and some blood flows back into the atrium. A leaking (or regurgitant) aortic valve allows blood to flow in two directions. Oxygen-rich blood either flows out through the aorta to the body – as it should – or it flows backwards from the aorta into the left ventricle when the ventricle relaxes. Leaking valves can cause the heart to work harder to pump the same amount of blood.

Acute Respiratory Distress Syndrome Pathophysiology
Acute Respiratory Distress Syndrome Pathophysiology samer kareem 2,171 Views • 2 years ago

ARDS was recognized as the most severe form of acute lung injury (ALI), a form of diffuse alveolar injury. The AECC defined ARDS as an acute condition characterized by bilateral pulmonary infiltrates and severe hypoxemia in the absence of evidence for cardiogenic pulmonary edema. The severity of hypoxemia necessary to make the diagnosis of ARDS was defined by the ratio of the partial pressure of oxygen in the patient’s arterial blood (PaO2) to the fraction of oxygen in the inspired air (FiO2). ARDS was defined by a PaO2/FiO2 ratio of less than 200, and in ALI, less than 300. This definition was further refined in 2011 by a panel of experts and is termed the Berlin definition of ARDS. [3] ARDS is defined by timing (within 1 wk of clinical insult or onset of respiratory symptoms); radiographic changes (bilateral opacities not fully explained by effusions, consolidation, or atelectasis); origin of edema (not fully explained by cardiac failure or fluid overload); and severity based on the PaO2/FiO2 ratio on 5 cm of continuous positive airway pressure (CPAP). The 3 categories are mild (PaO2/FiO2 200-300), moderate (PaO2/FiO2 100-200), and severe (PaO2/FiO2 ≤100).

35-38 weeks of Pregnancy, What to do? samer kareem 2,656 Views • 2 years ago

Your baby measures about 20.7 inches from head to toe and weighs about 6 pounds. The baby may drop lower in your abdomen, usually assuming the head-down position to prepare for birth. The brain has been developing rapidly, and your baby is practicing blinking. Mom-to-be: Your uterus has grown bigger these last few weeks and is probably up under your ribs. But you're in the home stretch! After this week, you'll see your doctor weekly. You may switch between fatigue and extra bursts of energy. You may also have an achier back and feel heaviness and discomfort in your buttocks and pelvis. Tip of the Week: Start stocking your freezer with foods that can be easily popped into the oven or microwave after you bring your baby home. Chili, casseroles, and other simple dishes can be prepared and frozen ahead of time for use later.

Ear Infection with  pus leaking
Ear Infection with pus leaking samer kareem 6,106 Views • 2 years ago

If your ear is leaking pus, you may have a hole in your eardrum.Your eardrum is stretched across the inner end of your ear canal. It vibrates when sound waves reach it, so you can hear. A hole in your eardrum can be caused by an ear infection. Fluid builds up behind the eardrum. The pressure of the fluid can tear the eardrum. Some people get a hole in the eardrum for other reasons, like hearing a very loud noise. If this happens, the ear may get infected because germs (bacteria) get through the hole. Ear infections happen to adults and children, but they're more common in children. Some things can make you more likely to get an ear infection with discharge. They include getting lots of colds and coughs, living in overcrowded housing, and eating a poor-quality diet

What is Cataract Surgery ? samer kareem 2,466 Views • 2 years ago

Most cataracts are associated with the aging process and are common among older Americans. In fact, according to the National Eye Institute (NEI), 68.3 percent of Americans 80 and older had cataracts in 2010. And the prevalence of cataracts in the U.S. is expected to grow significantly in the years ahead, due in part to the aging of the population. In 2010, roughly 24.4 million Americans had cataracts, and that number is projected to grow to 50.2 million by the year 2050, according to NEI.

Tapeworm in eye
Tapeworm in eye samer kareem 13,627 Views • 2 years ago

A tapeworm is a ribbon-shaped parasite that lives in human or animal intestines. They are uncommon in developed countries. There are a number of different types which all have slightly different life cycles. Tapeworm infection can come from animals such as pigs, sheep, cattle, fish, dogs and cats. Eating undercooked food contaminated with tapeworm cysts and eggs causes the infection. Tapeworm eggs are shed in stools and it is possible for infection to spread from person to person through the oral/anal route.

Oral therapy has potential for symptom relief. It has the advantage of no surgery. Disadvantages include ongoing medication therapy, risks of side effects, high out of pocket cost, and sometimes over time effectiveness diminishes. Certain men also do not like to take medications. This is the most common way to treat BPH. Medicines like Flomax, Cardura, Hytrin and Uroxatral have proven to be effective in the treatment of most cases. Alpha Blockers relieve the obstruction by trying to stop the process by which the construction occurs. They basically relax the smooth muscle cells in the prostate to relieve urinary obstruction. Like most medicines side effects can occur. They are mild in most cases and include dizziness on standing, feeling fatigued, loss of ability to ejaculate with orgasm.
