Live Surgery: Upper Eyelid Reconstruction - Tenzel Flap

Vertigo is a sense of rotation, rocking, or the world spinning, experienced even when someone is perfectly still. Many children attempt to create a sense of vertigo by spinning around for a time; this type of induced vertigo lasts for a few moments and then disappears. In comparison, when vertigo occurs spontaneously or as a result of an injury it tends to last for many hours or even days before resolving.

Leading cardiologists Valentin Fuster, MD, PhD, Director of Mount Sinai Heart and Herschel Sklaroff, MD, Clinical Professor of Medicine, Cardiology at Mount Sinai Heart were filmed for one-month for the “Making Rounds” documentary film as they cared for critically-ill heart patients in the Cardiac Care Unit at The Mount Sinai Hospital.

Watch Mount Sinai Heart doctors, fellows, residents, and nurses in action and saving lives demonstrating how simply listening to patients at the bedside remains medicine’s most indispensable tool over any technology.

In this film Mount Sinai Heart helps preserve the disappearing art and science of how to examine and diagnose patients at the bedside for future generations of physicians.

**This film was made possible by the generous support
of the McInerney Family.**

Transjugular intrahepatic portosystemic shunt or transjugular intrahepatic portosystemic stent shunting (commonly abbreviated as TIPS or TIPSS) is an artificial channel within the liver that establishes communication between the inflow portal vein and the outflow hepatic vein.

The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA (DNA replication) to produce two daughter cells.

Ingrown toenails occur in both men and women. According to the National Health Services (NHS), ingrown toenails may be more common in people with sweaty feet, such as teenagers. Older people may also be at higher risk because toenails thicken with age. Many things can cause an ingrown toenail, including: cutting toenails incorrectly (Cut straight across, since angling the sides of the nail can encourage the nail to grow into the skin.) irregular, curved toenails footwear that places a lot of pressure on the big toes, such as socks and stockings that are too tight or shoes that are too tight, narrow, or flat for your feet toenail injury, including stubbing your toe, dropping something heavy on your foot, or kicking a ball repeatedly poor posture improper foot hygiene, such as not keeping your feet clean or dry genetic predisposition

The word enuresis is derived from a Greek word (enourein) that means “to void urine.” It can occur either during the day or at night (though some restrict the term to bedwetting that occurs at night). Enuresis can be divided into primary and secondary forms.

A nerve root block is an injection of local anesthetic (numbing medicine) and steroid injected under X-ray guidance into the area where the nerve exits the spinal column. A nerve root block is usually ordered by your doctor for pain in the arm or leg that follows the path of a single nerve. A nerve root block may be diagnostic (a test to determine the source of your pain) and/or therapeutic (to relieve your pain). If you get a period of sustained pain relief from the injection, the block may be repeated. Sometimes the block is done to help identify whether or not surgery might be helpful and at what level such surgery might be most helpful.

The most common position of the uterus is anteverted (cervix angles forward) and anteflexed (body is flexed forward). The position of the uterus in the adult is liable to considerable variation, depending chiefly on the condition of the bladder and rectum. Adnexa: In gynecology, the appendages of the uterus, namely the ovaries, the Fallopian tubes, and the ligaments that hold the uterus in place.

Hyponatremia is defined as a serum sodium of less than 135 Meq per litre and occurs in upto 22 % of hospitalised patients. The causes of hyponatremia may be understood based on the pre-existing volume status of the patient which may either be hypovolemic, euvolemic or hypervolemic hyponatremia. This presentation discusses in detail, the causes of these underlying conditions. Also mentioned are the clinical features and management options and therapeutic sodium targets in patients with hyponatremia. Drugs such as demeclocycline and vaptans (Tolvaptan, Conivaptan) are also mentioned as management options which may be used on a case to case basis. Finally, the all important targets of sodium correction over 24 hours are also mentioned, along with a practical formula for calculation of sodium deficit which is explained with an example.

This video demonstrates how a broken nose is fixed using only local anesthesia and without sedation. Of course, this can also be performed while asleep.

How to approach histology for Human Anatomy students. Using a key will help get you through it! Add some penguin fairy dust will help too!

Please note: I mis-spoke and said "striated" instead of "stratified epithelium" a couple of times... apologies!

There are lots of histology keys out there, but the one I showed in the video is here: http://www.penguinprof.com/upl....oads/8/4/3/1/8431323

Details:

Tissue in the human body:

Epithelial: Is made of cells arranged in a continuous sheet with one or more layers, has apical & basal surfaces.

A basement membrane is the attachment between the basal surface of the cell & the underlying connective tissue.

Two types of epithelial tissues: (1) Covering & lining epithelia and (2) Glandular Epithelium.

The number of cell layers & the shape of the cells in the top layer can classify epithelium.

Simple Epithelium - one cell layer
Stratified epithelium - two or more cell layers
Pseudostratified Columnar Epithelium - When cells of an epithelial tissue are all anchored to the basement Membrane but not all cells reach the apical surface.
Glandular Epithelium -- (1) Endocrine: Release hormones directly into the blood stream and (2) Exocrine - Secrete into ducts.


Connective: contains many different cell types including: fibroblasts, macrophages, mast cells, and adipocytes. Connective Tissue Matrix is made of two materials: ground substance - proteins and polysaccharides, fiber -- reticular, collagen and elastic.

Classification of Connective Tissue:
Loose Connective - fibers & many cell types in gelatinous matrix, found in skin, & surrounding blood vessels, nerves, and organs.
Dense Connective - Bundles of parallel collagen fibers& fibroblasts, found in tendons& ligaments.
Cartilage - Cartilage is made of collagen & elastin fibers embedded in a matrix glycoprotein & cells called chondrocytes, which was found in small spaces.
Cartilage has three subtypes:
Hyaline cartilage -- Weakest, most abundant type, Found at end of long bones, & structures like the ear and nose,
Elastic cartilage- maintains shape, branching elastic fibers distinguish it from hyaline and
Fibrous Cartilage - Strongest type, has dense collagen & little matrix, found in pelvis, skull & vertebral discs.


Muscle: is divided into 3 categories, skeletal, cardiac and smooth.
Skeletal Muscle -- voluntary, striated, striations perpendicular to the muscle fibers and it is mainly found attached to bones.
Cardiac Muscle -- involuntary, striated, branched and has intercalated discs
Smooth Muscle -- involuntary, nonstriated, spindle shaped and is found in blood vessels & the GI tract.


Nervous: Consists of only two cell types in the central nervous system (CNS) & peripheral nervous system (PNS):
Neurons - Cells that convert stimuli into electrical impulses to the brain, and Neuroglia -- supportive cells.
Neurons -- are made up of cell body, axon and dendrites. There are 3 types of neurons:
Motor Neuron -- carry impulses from CNS to muscles and glands,
Interneuron - interpret input from sensory neurons and end responses to motor neurons
Sensory Neuron -- receive information from environment and transmit to CNS.
Neuroglia -- is made up of astrocytes, oligodendrocytes, ependymal cells and microglia in the CNS, and schwann cells and satellite cells in the PNS.
