Deep Tendon Reflexes Exam
Deep Tendon Reflexes Exam samer kareem 6,814 Views • 2 years ago

In a normal person, when a muscle tendon is tapped briskly, the muscle immediately contracts due to a two-neuron reflex arc involving the spinal or brainstem segment that innervates the muscle. The afferent neuron whose cell body lies in a dorsal root ganglion innervates the muscle or Golgi tendon organ associated with the muscles; the efferent neuron is an alpha motoneuron in the anterior horn of the cord. The cerebral cortex and a number of brainstem nuclei exert influence over the sensory input of the muscle spindles by means of the gamma motoneurons that are located in the anterior horn; these neurons supply a set of muscle fibers that control the length of the muscle spindle itself.

Surfactant Dysfunction
Surfactant Dysfunction samer kareem 1,465 Views • 2 years ago

Genetic surfactant dysfunction disorders are caused by mutations in genes encoding proteins critical for the production and function of pulmonary surfactant. These rare disorders may produce familial or sporadic lung disease, with clinical presentations ranging from neonatal respiratory failure to childhood- or adult-onset interstitial lung disease. An overview of these disorders is presented in the table.. Interstitial lung diseases in children until recently were categorized by their histologic appearance in a manner similar to that used for adult forms of interstitial lung disease (ILD). In children, the lung histopathology findings associated with desquamative interstitial pneumonitis (DIP) are now known to often result from genetic mechanisms that disrupt normal surfactant production and metabolism. By contrast, DIP in adults is considered to represent a distinct type of ILD, which is strongly associated with cigarette smoking and carries a relatively favorable prognosis [1]. These genetic disorders also result in histopathologic patterns other than DIP, including findings of pulmonary alveolar proteinosis and chronic pneumonitis of infancy. An understanding of the pathogenesis of these disorders permits a mechanistic classification as genetic surfactant dysfunction disorders instead of their previous classification based upon histologic appearance.

Sciatica Pain. samer kareem 11,297 Views • 2 years ago

Sciatica is often characterized by one or more of the following symptoms: Constant pain in only one side of the buttock or leg (rarely in both legs) Pain that is worse when sitting Leg pain that is often described as burning, tingling, or searing (versus a dull ache) Weakness, numbness, or difficulty moving the leg, foot, and/or toes A sharp pain that may make it difficult to stand up or walk Pain that radiates down the leg and possibly into the foot and toes (it rarely occurs only in the foot) Sciatica Causes and Treatments Video Watch: Sciatica Causes and Treatments Video Sciatic pain can vary from infrequent and irritating to constant and incapacitating. Symptoms are usually based on the location of the pinched nerve. While symptoms can be painful and potentially debilitating, it is rare that permanent sciatic nerve damage (tissue damage) will result, and spinal cord involvement is possible but rare.

Procedure for Prolapse & Hemorrhoids
Procedure for Prolapse & Hemorrhoids samer kareem 2,730 Views • 2 years ago

A surgeon begins the PPH stapled hemorrhoidectomy by inserting a circular anal dilator and obturator into the anal canal and then securing the dilator in place with four sutures. The surgeon then inserts a PPH anoscope into the obturator. Next, he places a circumferential purse-string suture of 2-0 Monocryl on a UR-6 needle 4 cm proximal to the dentate line. The surgeon opens a PPH stapler and places its anvil across the purse string. The stapler is then closed and fired; it is held closed for two minutes to improve hemostasis. Prior to firing the stapler in a female patient, the surgeon places a gloved finger in the vagina to ensure the vaginal mucosa and rectal-vaginal septum are not trapped within the jaws of the closed stapler. The surgeon then opens and removes the stapler.

Cholangitis

Cholangitis Email this page to a friend Email this page to a friend Facebook Twitter Google+ Cholangitis is an infection of the bile ducts, the tubes that carry bile from the liver to the gallbladder and intestines. Bile is a liquid made by the liver that helps digest food. Causes Cholangitis is most often caused by bacteria. This can occur when the duct is blocked by something, such as a gallstone or tumor. The infection causing this condition may also spread to the liver. Risk factors include a previous history of gallstones, sclerosing cholangitis, HIV, narrowing of the common bile duct, and rarely, travel to countries where you might catch a worm or parasite infection. Symptoms The following symptoms may occur: Pain on the upper right side or upper middle part of the abdomen. It may also be felt in the back or below the right shoulder blade. The pain may come and go and feel sharp, cramp-like, or dull. Fever and chills. Dark urine and clay-colored stools. Nausea and vomiting. Yellowing of the skin (jaundice), which may come and go.

The objectives of hemodialysis are to extract toxic nitrogenous substances from the blood and to remove excess water. In hemodialysis, the blood, laden with toxins and nitrogenous wastes, is diverted from the patient to a machine, a dialyzer, in which the blood is cleansed and then returned to the patient. Diffusion, osmosis, and ultrafiltration are the principles on which hemodialysis is based.

The toxins and wastes in the blood are removed by diffusion—that is, they move from an area of higher concentration in the blood to an area of lower concentration in the dialysate. The dialysate is a solution made up of all the important electrolytes in their ideal extracellular concentrations.

The electrolyte level in the patient’s blood can be brought
under control by properly adjusting the dialysate bath. The semipermeable membrane impedes the diffusion of large molecules,
such as red blood cells and proteins.
