LASIK or Laser-Assisted In Situ Keratomileusis is a surgical procedure intended to reduce a person's dependency on glasses or contact lenses.

LASIK surgery is most commonly performed as a cure for myopia (nearsightedness), but can also be used to cure hyperopia (farsightedness) or astigmatism (corneal irregularities).

LASIK is a procedure that permanently changes the shape of the cornea using a special laser and thus focusing the light rays exactly on the retina.

The steps of the procedure are as follows:

A suction ring is placed on the eye to stabilize and check the eye pressure.

The microkeratome, a cutting instrument, is attached to the suction ring.

The blade of the microkeratome is used to cut a flap in the cornea.

The exposed inner layer of the cornea is then reshaped with an excimer laser.

The corneal flap is returned to its original position.

LASIK is an ambulatory procedure; the patient can walk into the surgery center, have the procedure and walk out again and is awake the whole time. Occasionally, the doctor may administer a mild oral sedative.

Digoxin is derived from the leaves of a digitalis plant. Digoxin helps make the heart beat stronger and with a more regular rhythm. Digoxin is also used to treat atrial fibrillation, a heart rhythm disorder of the atria (the upper chambers of the heart that allow blood to flow into the heart).

In patients age ;::25, HPV DNA testing is the preferred next step in management if the initial cytology shows ASC-US. In this method, samples are collected for both cytology and reflex HPV DNA. If cytology results are positive, HPV DNA testing is performed. If cytology results are negative, the sample for HPV DNA is discarded. HPV DNA testing along with Pap smear at 3 years is recommended if initial cytology shows ASC-US but HPV DNA testing is negative

Cerebral hydatid disease (neurohydatidosis) is caused by Echinococcus granulosus or less commonly E. alveolaris or E. multilocularis. The larval stage is the cause of hydatid disease in humans 1. Epidemiology Cerebral hydatid disease is a rare parasitic infestation and accounts for 1-2 % of all cystic echinococcosis. Hydatid disease is endemic in the Mediterranean region, the Middle East, Africa, eastern part of Turkey, Australia and parts of South America 2. Clinical presentation Symptoms and signs include: focal neurological deficits headaches increased intracranial pressure hydrocephalus papilloedema and loss of vision altered mental status seizures (rare)

PURPOSE: Laparoscopic partial nephrectomy (LPN) is an alternative modality of treatment for small sized renal cell carcinoma. Robot assisted laparoscopic partial nephrectomy (RLPN) has also been performed with an advantage in repairing resected surface after tumor resection. We compare the periopera...

tive data of patients treated with laparoscopic partial nephrectomy with those of RLPN undertaken patients. MATERIAL AND METHOD: From September 2006 to April 2008, 22 patients were treated with LPN and 22 were RLPN. 3 arms were used for RLPN; camera was inserted through the 12mm, umbilical trocar port. The laparoscopic Bulldog clamp was used for the clamping of renal hilum. We retrospectively compared each group about tumor size, operation time, estimated blood loss, warm ischemic time and hospital stay. RESULT: Operation time of LPN was shorter than that of RLPN (p=0.033). Tumor size, estimated blood loss and hospital stay was not significant different in each group. No case had conversion to open surgery. 1 patient of RLPN group, however, had conversion to radical nephrectomy due to severe bleeding. CONCLUSION: RLPN was safe and feasible in small sized renal cell carcinoma. Warm ischemic time was reasonable and morbidity associated with RLPN was also low.
