In this video, Professor Dan Reinstein performs a bilateral LASIK procedure filmed in real-time to demonstrate the full 8 and-a-half minute procedure from multiple angles. The superior design and experience of the Carl Zeiss Meditec Visumax femtosecond Laser for flap creation is seen, where the patient is only in contact with the device for about 30 seconds with extremely low contract force such that the patient feels effectively nothing, there are no red splodges (subconjunctival haemorages) left behind. From the surgeons' standpoint there is no device that is easier to use or faster for LASIK flap creation. The Carl Zeiss Meditec MEL80 excimer laser portion of the procedure is seamlessly integrated and incorporates all the features that make clinical outcomes so reproducible including the unique cone-for-controlled-atmosphere (CCA) and high efficiency, high sensitivity calibration test which can be performed for each individual patient to compensate for minor changes in energy that occur with excimer laser devices during the course of a day.

How chronic obstructive pulmonary disease  develops
How chronic obstructive pulmonary disease develops samer kareem 1,617 Views • 3 years ago

COPD (chronic obstructive pulmonary disease) makes it hard for you to breathe. The two main types are chronic bronchitis and emphysema. The main cause of COPD is long-term exposure to substances that irritate and damage the lungs. This is usually cigarette smoke. Air pollution, chemical fumes, or dust can also cause it. At first, COPD may cause no symptoms or only mild symptoms. As the disease gets worse, symptoms usually become more severe. They include A cough that produces a lot of mucus Shortness of breath, especially with physical activity Wheezing Chest tightness Doctors use lung function tests, imaging tests, and blood tests to diagnose COPD. There is no cure. Treatments may relieve symptoms. They include medicines, oxygen therapy, surgery, or a lung transplant. Quitting smoking is the most important step you can take to treat COPD.

As long as the ureter is large enough to allow the ureteroscope to pass, there is a good chance that the stone can be broken and removed with one surgery. Compared to SWL, a kidney or ureteral stone can be seen under direct vision by the ureteroscope, allowing lithotripsy with lasers followed by basketting and removal.

How osteoporosis develops
How osteoporosis develops samer kareem 13,124 Views • 3 years ago

Osteoporosis is a disease in which bones become brittle and fragile due to low bone mass and bone tissue loss. It's the most common type of bone disease, according to the National Institutes of Health (NIH), and increases your risk of fractures, particularly of the hips, spine, and wrists. Prevalence In the United States, nearly 54 million people ages 50 and older were living with osteoporosis or osteopenia (low bone mass ) in 2010, according to a 2014 article in the Journal of Bone and Mineral Research. More specifically, 10.2 million adults had osteoporosis, and 43.4 million adults had osteopenia, which puts a person at high risk for osteoporosis.

Popping a Large Abscess In A Young Female. Scott 4,870 Views • 3 years ago

She is a twenty years young female presented with large cystic swelling in anterior aspect of neck. The swelling was of size 6cmx 6cm x5 cm ,tense tender, cystic just above sternal nutch.This was diagnosed as large neck abscess ./nRepeated aspiration done but the swelling reappeared. So Incision & Drainage planned under local anaesthesia./nPatient in supine position. Surgery part painted and draped. Local anaesthesia 2% xylocaine with adrenaline used for field block.After giving local anaesthesia, I used a no 11 blade for stab incision at the most prominent part of the swelling, where skin was thin and fluctuation present./nPus drained form that opening. Little dilatation of opening to be done with artery forceps or sinus forceps. Complete pus drainage to be ensured.Little finger can be introduced inside the pus cavity to ensure proper drainage of pus. The cavity I use to clean with a gauge piece. If necessary curette biopsy can be taken from the wall of the cavity.These wounds usually need daily proper dressing for faster healing.

Spinal Injury - Jaw Thrust
Spinal Injury - Jaw Thrust samer kareem 5,703 Views • 3 years ago

The jaw thrust is a method of opening the airway of a patient. The airway is very important in first aid! It consists of the structures in the back of the throat and upper neck. A patient who is unconscious is not able to maintain their own airway as it can become blocked by the tongue (see picture). Normally, first aid courses teach the head tilt – chin lift technique to open an airway. However, this airway manoeuvre involves significant movement of the patient’s neck. Therefore if there is any suspicion of a spinal (neck) injury it may cause further damage.

Biceps tenodesis surgery is performed when the biceps tendon is damaged, or the rotator cuff tendon or cartilage ring in the shoulder is torn. The biceps tendon is a strong rope‐like structure connecting the upper end of the biceps muscle to the bones in the shoulder. In biceps tenodesis surgery, the biceps tendon is separated from the shoulder and reattached to the humerus, or the upper arm bone.

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.

It involves placing a small, expandable tube called a stent in the narrowed artery. This procedure is also called carotid angioplasty and stenting. There are two carotid arteries-one on each side of the neck-that supply blood to the brain. These arteries can be narrowed and damaged by fatty deposits called plaque.

Caesarean section for a breech
Caesarean section for a breech Mohamed Ibrahim 26,630 Views • 3 years ago

Caesarean section is the most common way to deliver a breech baby in the USA, Australia, and Great Britain. Like any major surgery, it involves risks. Maternal mortality is increased by a Caesarean section, but still remains a rare complication in the First World. Third World statistics are dramatically different, and mortality is increased significantly. There is remote risk of injury to the mother’s internal organs, injury to the baby, and severe hemorrhage requiring hysterectomy with resultant infertility. More commonly seen are problems with noncatastrophic bleeding, postoperative infection and wound healing problems. It should be added that the increase in maternal mortality rates could be slightly skewed due to the fact that Caesarean sections are often used during high-risk pregnancies and/or when mortality is already a strong possibility.

One large study has confirmed that elective cesarean section has lower risk to the fetus and a slightly increased risk to the mother, than planned vaginal delivery of the breech however elements of the methodology used have undergone some criticism.

The same birth injuries that can occur in vaginal breech birth may rarely occur in Caesarean breech delivery. A Caesarean breech delivery is still a breech delivery. However the soft tissues of the uterus and abdominal wall are more forgiving of breech delivery than the hard bony ring of the pelvis. If a Caesarean is scheduled in advance (rather than waiting for the onset of labor) there is a risk of accidentally delivering the baby too early, so that the baby might have complications of prematurity. The mother’s subsequent pregnancies will be riskier than they would be after a vaginal birth (uterine rupture). The presence of a uterine scar will be a risk factor for any subsequent pregnancies.
