This video is designed for my introductory A&P course to study the endocrine system. This tutorial will take you through the various endocrine organs, hormones produced, and effects at each tissue. Prolactin is one of the 5 hormones we are studying of the anterior pituitary. SHOW MORE
Peripheral arterial disease (P.A.D.) occurs when plaque (plak) builds up in the arteries that carry blood to your head, organs, and limbs. Plaque is made up of fat, cholesterol, calcium, fibrous tissue, and other substances in the blood. When plaque builds up in arteries, the condition is called atherosclerosis (ATH-er-o-skler-O-sis). Over time, plaque can harden and narrow the arteries. This limits the flow of oxygen-rich blood to your organs and other parts of your body. P.A.D. usually affects the legs, but also can affect the arteries that carry blood from your heart to your head, arms, kidneys, and stomach. This article focuses on P.A.D. that affects blood flow to the legs.
There are a few different kinds of emergency contraception. The best kind for you depends on a few factors — when you had sex, your weight, whether you’re breastfeeding, and what kind is easiest for you to get. Here’s what you need to know.
49-years old patient complaining of cough, fever and pleuritic pain for 2 weeks. At admission he was febrile and tachypnic. Chest X-Ray showed left pleural effusion. Thoracocentesis revealed purulent fluid. Chest CT-scan showed large and loculated left pleural effusion and pleural thickening. VATS decortication was performed through three incisions.

A subdural hematoma is most often the result of a severe head injury. This type of subdural hematoma is among the deadliest of all head injuries. The bleeding fills the brain area very rapidly, compressing brain tissue. This often results in brain injury and may lead to death. Subdural hematomas can also occur after a minor head injury. The amount of bleeding is smaller and occurs more slowly. This type of subdural hematoma is often seen in older adults. These may go unnoticed for many days to weeks, and are called chronic subdural hematomas. With any subdural hematoma, tiny veins between the surface of the brain and its outer covering (the dura) stretch and tear, allowing blood to collect. In older adults, the veins are often already stretched because of brain shrinkage (atrophy) and are more easily injured.
What is peripheral neuropathy? Your peripheral nervous system connects the nerves from your brain and spinal cord, or central nervous system, to the rest of your body. This includes your: arms hands feet legs internal organs mouth face The job of these nerves is to deliver signals about physical sensations back to your brain.
Robotic-assisted endoscopic thyroid surgery using the daVinci® Surgical System can safely and effectively offer those needing thyroid surgery relief without neck incisions. Dr. Ron Kuppersmith and Dr. Andrew deJong are now performing this procedure at the College Station Medical Center in Texas.
Bronchiectasis is an abnormal dilation of the proximal and medium-sized bronchi (>2 mm in diameter) caused by weakening or destruction of the muscular and elastic components of the bronchial walls. Affected areas may show a variety of changes, including transmural inflammation, edema, scarring, and ulceration, among other findings. Distal lung parenchyma may also be damaged secondary to persistent microbial infection and frequent postobstructive pneumonia. Bronchiectasis can be congenital but is most often acquired.[9] Congenital bronchiectasis usually affects infants and children. These cases result from developmental arrest of the bronchial tree. Acquired forms occur in adults and older children and require an infectious insult, impairment of drainage, airway obstruction, and/or a defect in host defense. The tissue is also damaged in part by the host response of neutrophilic proteases, inflammatory cytokines, nitric oxide, and oxygen radicals. This results in damage to the muscular and elastic components of the bronchial wall. Additionally, peribronchial alveolar tissue may be damaged, resulting in diffuse peribronchial fibrosis.[12] The result is abnormal bronchial dilatation with bronchial wall destruction and transmural inflammation. The most important functional finding of altered airway anatomy is severely impaired clearance of secretions from the bronchial tree. Impaired clearance of secretions causes colonization and infection with pathogenic organisms, contributing to the purulent expectoration commonly observed in patients with bronchiectasis. The result is further bronchial damage and a vicious cycle of bronchial damage, bronchial dilation, impaired clearance of secretions, recurrent infection, and more bronchial damage
Pulmonary hypertension is a type of high blood pressure that affects the arteries in your lungs and the right side of your heart. In one form of pulmonary hypertension, tiny arteries in your lungs, called pulmonary arterioles, and capillaries become narrowed, blocked or destroyed. This makes it harder for blood to flow through your lungs, and raises pressure within your lungs' arteries. As the pressure builds, your heart's lower right chamber (right ventricle) must work harder to pump blood through your lungs, eventually causing your heart muscle to weaken and fail. Some forms of pulmonary hypertension are serious conditions that become progressively worse and are sometimes fatal. Although some forms of pulmonary hypertension aren't curable, treatment can help lessen symptoms and improve your quality of life. Pulmonary hypertension care at Mayo Clinic
It depends upon which ligament is injured. If it is medial collateral ligament you feel pain when you walk ,sit and stand and you will be liming as well. If it is anterior cruciate ligament you feel pain when you walk on uneven ground.
With keratoconus, the clear, dome-shaped tissue that covers the eye (cornea) thins and bulges outward into a cone shape. Its cause is unknown. Symptoms first appear during puberty or the late teens and include blurred vision and sensitivity to light and glare. Vision can be corrected with glasses or contact lenses early on. Advanced cases may require a cornea transplant.
