On Tuesday May 29th at 3:00pm EDT, University Hospitals Case Medical Center Cleveland, Ohio, will host a live webcast to demonstrate the removal of brain tumor and epileptic focus from an awake patient using intra-operative MRI and brain mapping. See this on OR-Live.com

The patient was a middle-aged gentleman with new onset seizures. An MRI showed what appeared to be a low grade glioma near the motor strip on the right. Studies have shown that complete removal can cure the seizures, improve quality of life and survival, but this is difficult to do with conventional technology without harming the surrounding normal brain because its difficult to determine where tumor ends and normal brain begins.

What is Laparoscopic Cholecystectomy?
What is Laparoscopic Cholecystectomy? Surgeon 100 Views • 3 years ago

Cholecystectomy means removal of the gallbladder. The most common reasons
your doctor might recommend a cholecystectomy are biliary colic, cholecystitis,
choledocolithiasis, or gallstone pancreatitis. Biliary colic, also known as symptomatic
cholelithiasis, is caused by gallstones, which are hardened deposits of bile. Gallstones are
common in the general population, and gallstones alone are not a reason for gallbladder
removal if they do not cause symptoms. However, sometimes gallstones can get caught at the
neck of the gallbladder, causing pain when the gallbladder contracts against them trying to
release its bile, especially after a fatty meal. With biliary colic, the pain typically resolves within
an hour or so. Occasionally, a stone or some other blockage may prevent the gallbladder from
emptying over a long period of time, causing an increase in pressure and trapped fluid within the
gallbladder. This can cause inflammation and infection of the gallbladder, which we call
cholecystitis. Choledocholithiasis is when there are one or more stones in the bile ducts, which
can cause back up of bile into the liver, and depending on the location of the stones, could
cause pancreatitis, which is inflammation of the pancreas. Other reasons for gallbladder
removal, though less common, are gallbladder polyps and cancer. All of these are reasons for
gallbladder removal.

Help with Histology
Help with Histology DrPhil 96 Views • 3 years ago

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.

Laparoscopically Assisted Vaginal Hysterectomy
Laparoscopically Assisted Vaginal Hysterectomy samer kareem 2,868 Views • 3 years ago

procedure is usually done in the hospital or outpatient surgical center under general anesthesia (while you are asleep and pain-free). The procedure is performed in the following way: The surgeon makes a small cut (incision) below the belly button (navel). A needle or tube is inserted into the incision. Carbon dioxide gas is passed into the abdomen through the needle or tube. The gas helps expand the area, giving the surgeon more room to work, and helping the surgeon see the organs more clearly. A tube is placed through the cut in your abdomen. A tiny video camera (laparoscope) goes through this tube and is used to see the inside of your pelvis and abdomen. More small cuts may be made if other instruments are needed to get a better view of certain organs. If you are having gynecologic laparoscopy, dye may be injected into your cervix area so the surgeon can view your fallopian tubes. After the exam, the gas, laparoscope, and instruments are removed, and the cuts are closed. You will have bandages over those areas.

Prevent Vitamin D Deficiency
Prevent Vitamin D Deficiency samer kareem 2,134 Views • 3 years ago

You may have recently found out that you are deficient or know someone who is. It's shocking for most people when they have never had a problem before and believe nothing has changed to make it a problem now. The truth is that a lot has changed, and vitamin D deficiency and insufficiency is now a global public-health problem affecting an estimated 1 billion people worldwide. The most well-known consequences to not having enough vitamin D are rickets in children and osteomalacia in adults. These are far from the only problems associated with a vitamin D deficiency.

Direct Laryngoscopy
Direct Laryngoscopy samer kareem 7,459 Views • 3 years ago

Visualization of the larynx by direct or indirect means is referred to as laryngoscopy and is the principal aim during airway management for passage of a tracheal tube. This paper presents a brief background regarding the development and practice of laryngoscopy and examines the equipment and techniques for both direct and indirect methods. Patient evaluation during the airway examination is discussed, as are predictors for difficult intubation. Laryngoscope blade design, newer intubating techniques, and a variety of indirect laryngoscopic technologies are reviewed, as is the learning curve for these techniques and devices.

What is Scoliosis surgery?
What is Scoliosis surgery? Scott 6,179 Views • 3 years ago

Most scoliosis surgeons agree that children who have very severe curves (45-50° and higher) will need surgery to lessen the curve and prevent it from getting worse. The operation for scoliosis is a spinal fusion. The basic idea is to realign and fuse together the curved vertebrae so that they heal into a single, solid bone. With the tools and technology available today, scoliosis surgeons are able to improve curves significantly.
