Purpose: To evaluate the results of LASIK and IntraLASIK treatment in myopic patients with nystagmus. Methods: Eight patients with congenital nystagmus (16 eyes), from 23 to 49 years of age, underwent LASIK surgery. Corneal flaps were created using either the Hansatome microkeratome or the Intral...ase femtosecond laser. The ablations were performed with the Bausch & Lomb excimer laser with an active tracking system. In some patients, the eyes were fixated with forceps or a fixation ring during the laser ablation. Results: The refractive errors were corrected in all cases. There was no decentration or loss of best corrected visual acuity greater than 1 line. In 56% of the eyes, the post-operative uncorrected visual acuity was better than the best spectacle corrected-visual acuity (BSCVA). 62.5% of the eyes improved their BSCVA. The overall visual performance was improved in all the patients. One patient that did not not drive before become eligible to get a driver license after the surgery. Conclusions: Selected patients with myopia and congenital nystagmus may benefit from laser refractive surgery. Laser refractive surgery may be safely and accurately performed by using either the Hansatome microkeratome or the Intralase femtosecond laser and an active tracking system with or without mechanical fixation. Certain patients improve their BSCVA post-operatively.
Following Dr. Eric Skarsgard on his grueling 19-hour day at BC Children's Hospital, we meet several of his patients -- some of who need surgery that day, and some who have chronic conditions and need regular check-ups with him -- and learn how he works with medical students and on research projects as time allows.
Obesity is the abnormal condition that causes a person to put on excessive amounts of weight due to accumulation of fat in their body. This extreme weight causes a variety of other disorders and diseases as complications associated with it. https://goo.gl/GgSAoY
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.
LASIK eye surgery is commonly performed laser refractive surgery to correct vision problems. This 3d animation shows how laser-assisted in situ keratomileusis (lasik) can be an alternative to glasses or contact lenses.
It’s one of many vision correction surgeries that work by reshaping your cornea, the clear front part of your eye, so that light focuses on the retina in the back of your eye.
In eyes with normal vision, the cornea bends (refracts) light precisely onto the retina at the back of the eye. But with nearsightedness (myopia), farsightedness (hyperopia) or astigmatism, the light is bent incorrectly, resulting in blurred vision.
During LASIK surgery, a special type of cutting laser is used to precisely change the shape of the dome-shaped clear tissue at the front of your eyes (cornea) to improve vision.
Glasses or contact lenses can correct vision, but reshaping the cornea itself also will provide the necessary refraction.

The bone marrow aspiration is usually done first. The doctor makes a small incision, then inserts a hollow needle through the bone and into the bone marrow. Using a syringe attached to the needle, the doctor withdraws a sample of the liquid portion of the bone marrow. You may feel a brief sharp pain or stinging.

A uterine fibroid (also uterine leiomyoma, myoma, fibromyoma, leiofibromyoma, fibroleiomyoma, and fibroma) (plural of ... myoma is ...myomas or ...myomata) is a benign (non-cancerous) tumor that originates from the smooth muscle layer (myometrium) and the accompanying connective tissue of the uterus. Fibroids are the most common benign tumors in females and typically found during the middle and later reproductive years. While most fibroids are asymptomatic, they can grow and cause heavy and painful menstruation, painful sexual intercourse, and urinary frequency and urgency. Uterine fibroids is the major indication for hysterectomy in the US.[2] Fibroids are often multiple and if the uterus contains too many leiomyomatas to count, it is referred to as uterine leiomyomatosis. The malignant version of a fibroid is uncommon and termed a leiomyosarcoma.
