How do you assess cerebellar function? Ask them to do this as fast as possible while you slowly move your finger. Repeat the test with the other hand. Perform the heel-to-shin test. Have the patient lying down for this and get them to run the heel of one foot down the shin of the other leg, and then to bring the heel back up to the knee and start again.

End Stage Liver Disease samer kareem 1,477 Views • 2 years ago

In the United States, end-stage liver disease (ESLD) is the 12th leading cause of death and the 7th leading cause of death in people between the ages of 25 and 64 years. Complications of ESLD such as ascites, variceal hemorrhage, hepatic encephalopathy, and renal impairment primarily account for these deaths. Patients with ESLD require increasingly complex medical support and manifest a spectrum of complications and symptoms that have significant impact on both survival and quality of life.

Automated External Defibrillator
Automated External Defibrillator Doctor 10,362 Views • 2 years ago

An automated external defibrillator or AED is a portable electronic device that automatically diagnoses the potentially life threatening cardiac arrhythmias of ventricular fibrillation and ventricular tachycardia in a patient,[1] and is able to treat them through defibrillation, the application of electrical therapy which stops the arrhythmia, allowing the heart to reestablish an effective rhythm. The first AED was originally designed and created by American biomedical engineer Joshua L. Koelker and Italian emergency medical professional Jordan M. Blondino to allow defibrillation in common public places. AEDs are designed to be simple to use for the layman, and the use of AEDs is taught in many first aid, first responder, and basic life support (BLS) level CPR classes.

Anal Fistula and Anal Abscess
Anal Fistula and Anal Abscess samer kareem 11,072 Views • 2 years ago

While an anal abscess is an infection within one or more of the anal spaces, an anal fistula (Choice B) is a tunneling between the anus or rectum and another epithelial lined space (eg, the skin overlying the drainage site). Fifty percent of patients with anal abscesses will go on to develop a chronic fistula from the involved anal gland to the overlying skin. Patients with fistulas typically present with an anal abscess that persists after incision and drainage, or with a pustule-like lesion in the perianal or ischiorectal area that continually drains. Surgical repair is usually necessary to eliminate the fistula while preserving fecal continence.

Epidermoid cysts, also called sebaceous, keratin, or epithelial cysts, are small, hard lumps that develop under the skin. These cysts are common. They grow slowly. They do not cause other symptoms and are nearly never cancerous. Epidermoid cysts are often found on the face, head, neck, back, or genitals

In this video Erin K, a tubal reversal patient, explains the symptoms she experienced while suffering from Post Tubal Ligation Syndrome (PTLS). After having tubal reversal surgery her symptoms were relieved. Although numerous women suffer from adverse symptoms after having a tubal ligation, many physicians do not believe PTLS exists. In an ongoing study of over 300 patients reporting Post Tubal Ligation symptoms more than 90% have found relief after tubal reversal at Chapel Hill Tubal Reversal Center.

HIV Virus Life Cycle and Drug Reaction
HIV Virus Life Cycle and Drug Reaction Magdy 11,448 Views • 2 years ago

Binding and Fusion: HIV begins its life cycle
when it binds to a CD4 receptor and one of two
co-receptors on the surface of a CD4+
Tlymphocyte. The virus then fuses with the host
cell. After fusion, the virus releases RNA, its
genetic material, into the host cell.

Reverse Transcription: An HIV enzyme
called reverse transcriptase converts the singlestranded HIV RNA to double-stranded HIV DNA.

Integration: The newly formed HIV DNA
enters the host cell's nucleus, where an HIV
enzyme called integrase "hides" the HIV DNA
within the host cell's own DNA. The integrated
HIV DNA is called provirus. The provirus may
remain inactive for several years, producing few or
no new copies of HIV

Transcription: When the host cell receives a
signal to become active, the provirus uses a host
enzyme called RNA polymerase to create copies of
the HIV genomic material, as well as shorter
strands of RNA called messenger RNA (mRNA).
The mRNA is used as a blueprint to make long
chains of HIV proteins.

Assembly: An HIV enzyme called protease cuts
the long chains of HIV proteins into smaller
individual proteins. As the smaller HIV proteins
come together with copies of HIV's RNA genetic
material, a new virus particle is assembled.

Budding: The newly assembled virus pushes out
("buds") from the host cell. During budding, the new
virus steals part of the cell's outer envelope. This
envelope, which acts as a covering, is studded with
protein/sugar combinations called HIV
glycoproteins. These HIV glycoproteins are
necessary for the virus to bind CD4 and coreceptors. The new copies of HIV can now move
on to infect other cells.

Polyarteritis nodosa Email this page to a friend Email this page to a friend Facebook Twitter Google+ Polyarteritis nodosa is a serious blood vessel disease. The small and medium-sized arteries become swollen and damaged. Causes Arteries are the blood vessels that carry oxygen-rich blood to organs and tissues. The cause of polyarteritis nodosa is unknown. The condition occurs when certain immune cells attack the affected arteries. More adults than children get this disease. The tissues that are fed by the affected arteries do not get the oxygen and nourishment they need. Damage occurs as a result. People with active hepatitis B or hepatitis C may develop this disease.
