Why You Got Fat
Why You Got Fat samer kareem 26,619 Views • 3 years ago

The usual reason given for people getting fat is that they eat too much and/or exercise too little. That reflects one of the basic laws of thermodynamics—I forget which one. The amount of energy you put into a system minus the energy you take out has to be stored somewhere i.e. FAT! This formulation—true though it is—does not entirely explain obesity since some people seem to eat more than fat people and exercise no more than these same fat people, and yet they are not fat! Chalking this fact up to the general perversity of the universe is not sufficient explanation. Other factors must come into play. I mention below some of the ideas thoughtful people have proposed to explain why fat people become fat:

Warfarin is an anticoagulant medication - it is used to slow down the blood-clotting process. Anticoagulants are used to prevent blood clots which may cause vein blockages, heart attack and stroke. Warfarin is known under the brand names Warfant, Jantoven, Coumadin, Lawarin, Marevan, and Waran.

Timed Up & Go Test
Timed Up & Go Test samer kareem 5,604 Views • 3 years ago

The "Get up and go" test is most commonly used to assess postural stability. In this test, the physician instructs the patient to stand up from a chair without assistance, walk a short distance, turn around, return, and sit down again. If the patient is unsteady or has difficulties during the test, further evaluation is necessary.

Herpes Encephalitis
Herpes Encephalitis samer kareem 7,442 Views • 3 years ago

Herpes simplex encephalitis is characterized by acute-onset (<1 week) fever, headaches, seizures, altered mental status, and focal neurologic findings such as hemiparesis or cranial nerve deficits. This patient's weakness/fatigue for >1 week, heart murmur, history of drug abuse, and absence of focal neurologic deficits make endocarditis with mycotic aneurysm more likely than herpes encephalitis

Treating Scoliosis with Magnets
Treating Scoliosis with Magnets samer kareem 18,034 Views • 3 years ago

Pediatric orthopedic surgeons at Columbia are using a new device with magnetic technology that avoids the need for multiple spine-lengthening surgeries to correct early-onset scoliosis, a severe curvature of the spine in young children. In April 2014, Michael Vitale, MD, the Ana Lucia Professor of Pediatric Orthopedic Surgery at CUMC and 1995 graduate of P&S, performed the first procedure in the New York area, using the device to treat a 5-year-old boy. When braces and casts cannot control scoliosis in young children, surgeons turn to growing rods, which help correct the curve while allowing the spine to grow. When spinal maturity is near, the rods are removed and a spinal fusion can be performed. But during years of treatment with growing rods, patients must undergo surgery every six months to lengthen the rods to keep up with the patients’ growth. A patient may undergo eight to 10 procedures, which are costly and result in lost time for parents at work and children at school. The new device—MAGEC (MAGnetic Expansion Control) rods—contains a mechanism inside the growing rods that allows surgeons to lengthen the rods with a handheld external magnet, without surgery.

HIV Testing for Infants
HIV Testing for Infants samer kareem 4,308 Views • 3 years ago

Diagnosis of HIV infection in infants is aided by HIV culture or DNA/RNA polymerase chain reaction (PCR); positive results are confirmed by repeating the test. In suspected cases, HIV testing should occur in the newborn period (ie, before the infant is 48 h old), at age 1-2 months, and again at age 3-6 months.

Phenylketonuria Genetics
Phenylketonuria Genetics samer kareem 1,265 Views • 3 years ago

Classical PKU is an autosomal recessive disorder, caused by mutations in both alleles of the gene for phenylalanine hydroxylase (PAH), found on chromosome 12. In the body, phenylalanine hydroxylase converts the amino acid phenylalanine to tyrosine, another amino acid.

Instead of permanently joining (fusing) vertebrae with metal rods and screws, and therefore restricting movement, the new procedure uses the Anatomic Facet Replacement System (AFRS) device that attaches to each of two adjacent vertebrae with a movable joint that mimics the spine's natural joint.

Syndrome of inappropriate antidiuretic Hormone samer kareem 1,349 Views • 3 years ago

What is syndrome of inappropriate antidiuretic hormone (SIADH)? Well, SIADH is a condition where too much ADH hormone is released, which causes an increase in blood volume and ultimately leads to a series of complications related to the blood osmolality and osmolarity

Coronary artery vasospasm, or smooth muscle constriction of the coronary artery, is an important cause of chest pain syndromes that can lead to myocardial infarction (MI), ventricular arrhythmias, and sudden death. It also plays a key role in the development of atherosclerotic lesions.Nov 22, 2016

Treatment of Pneumothorax samer kareem 2,805 Views • 3 years ago

A pneumothorax (noo-moe-THOR-aks) is a collapsed lung. A pneumothorax occurs when air leaks into the space between your lung and chest wall. This air pushes on the outside of your lung and makes it collapse. In most cases, only a portion of the lung collapses.

Dementia Signs and Symptoms
Dementia Signs and Symptoms samer kareem 1,274 Views • 3 years ago

Dementia is not a specific disease. It's an overall term that describes a wide range of symptoms associated with a decline in memory or other thinking skills severe enough to reduce a person's ability to perform everyday activities. Alzheimer's disease accounts for 60 to 80 percent of cases. Vascular dementia, which occurs after a stroke, is the second most common dementia type. But there are many other conditions that can cause symptoms of dementia, including some that are reversible, such as thyroid problems and vitamin deficiencies.
