McCannel Suture fixation of IOL to iris using standard and Sipser-chang technique
McCannel Suture fixation of IOL to iris using standard and Sipser-chang technique Scott 19,309 Views • 3 years ago

Here Drs Oetting and Shriver of the University of Iowa demonstrate the McCannel technique of fixing an IOL to the iris. In this video both the standard McCannel suture retrieval technique and the Siepser/Chang modifed technique are demonstrated. A 10-O prolene with a long curved ctc-6 needle is u...sed to place a suture through the iris and under an 3 piece IOL haptic. Using the standard technique the two ends of the suture are retrieved through a common paracentesis near the fixation site and tied externally. The other haptic is tied using the Siepser sliding knot technique as described by Chang for this indication with an internal knot. The standard technique is a bit easier but does not allow as thight a knot for fixation of the iris to the haptic.

Arterial Anastomosis
Arterial Anastomosis samer kareem 1,800 Views • 3 years ago

Throughout the body, there are several points at which blood vessels unite. The junctions are termed anastomoses. In the simplest sense, an anastomosis is any connection (made surgically or occurring naturally) between tube-like structures. Naturally occurring arterial anastomoses provide an alternative blood supply to target areas in cases where the primary arterial pathway is obstructed. They are most abundant in regions of the body where the blood supply may can be easily damaged or blocked (such as the joints or intestines). This article focuses on the arterial anastomotic networks of the upper limb.

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.

Cleft Palate Surgery: Preparing for your procedure at C.S. Mott Children's Hospital
Cleft Palate Surgery: Preparing for your procedure at C.S. Mott Children's Hospital Surgeon 275 Views • 3 years ago

Cleft palate is among the most common birth defects affecting children in North America. The incomplete formation of the roof of the mouth can occur individually, or in addition to cleft lip. Cleft palate repair is a type of plastic surgery to correct this abnormal development both to restore function and a more normal appearance. This video explains what to expect for families scheduled for cleft palate surgery at the Craniofacial Anomalies Program at University of Michigan C.S. Mott Children's Hospital.

Cervical screening test
Cervical screening test samer kareem 22,238 Views • 3 years ago

Women are routinely invited to have cervical screening tests (also called smear tests). The tests are done to prevent cervical cancer, not to diagnose cancer. During each test some cells are removed from the neck of the womb (cervix), with a plastic brush. The cells are examined under a microscope to look for early changes that, if ignored and not treated, could develop into cancer of the cervix. You are very unlikely to develop cervical cancer if you have regular cervical screening tests at the times advised by your doctor. If the test shows any abnormality, you will have treatment to stop you ever getting cancer of the cervix. So, an abnormal test does not mean you have cancer. It means you should have some treatment to stop you getting cancer.

Oral ULcer
Oral ULcer samer kareem 1,548 Views • 3 years ago

Mouth ulcers are sores that appear in the mouth, often on the inside of the cheeks. Mouth ulcers, also known as aphthous ulcers, can be painful when eating, drinking or brushing teeth. Occasional mouth ulcers are usually harmless and clear up on their own. Seek medical advice if they last longer than 3 weeks or keep coming back. Mouth ulcers cannot be caught from someone else. Up to 1 in 5 people get recurrent mouth ulcers.
