This short clinical-skills video demonstrates an intramuscular injection being given to a female patient. Intramuscular injections deliver medication deep into the muscle tissue, and correct site selection and technique are essential parts of everyday nursing and clinical practice.

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.

Challenges of cataract surgery in the eye with a history of radial keratotomy include IOL power calculation, protection of the cornea and aviodance of capsular complications.

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.

The challenge of position a patient with severe kyphosis for cataract extraction and lens implantation is met with a team effort and ingenuity.

This task requires streching a rubber band around 16 nails on a wooden board. A penalty is calculated when the rubber band is not streched around a nail at the end of the task. Score = time (seconds) + number of missed nails x 10. Performance standard: Score = 62 sec [Kolkman 2008]

A cesarean section birth is shown in this childbirth surgery video. The recording presents the operative delivery of a baby through an incision in the abdomen and uterus. It is an educational resource for students of obstetrics learning about surgical delivery and its main steps.

Intravenous injection is taught in this clinical skills demonstration video. The recording shows the technique for administering an injection into a vein in a clinical setting. It is a training resource for medical and nursing students learning intravenous medication administration.

Laparoscopic Vaginal Top Closure

Endometrial Ablation

Total laparoscopic hysterectomy using staples to secure major blood vessels. Vaginal colpotomy and mobilization of bladder performed initally with suture line at junction of vagina and cervix visualized laparoscopically.

Repair performed with the PROLIFT Pelvic Floor Repair System - the total implant. The objective of the PROLIFT procedure is to achieve a a complete anatomic repair of pelvic floor defects in a standardized way. The repair is achieved by the placement of the synthetic non-absorbable polyprolylen mesh... implant via a vaginal approach.

We noticed a blue-line in the endometrial cavity between the tubal ostiae after injection of methylene blue (to determine tubal patency). We have seen this “blue-line” even in cases with normal or unicornuate uterus and/or in cases with patent or occluded fallopian tubes(Picture 1). So the be...st explanation of this finding may be the high speed jet or turbulence of dye in the top or the deepest part of endometrial cavity. We simply postulated that the zone which holds the methylene blue is the zone where the flashing dye strikes vertically over there and the dye penatrates into the endometrial epithelium and glands. We used this line as a guide that shows midline during operative hysteroscopy ( especially in cases with septate uterus) and we don’t ecxatly know reason why it occurs. It is necessary to perform histologic, molecular or clinical studies on this subject. It may have a multifactorial aetiology. We performed a prospective case control study and will publish it soon after when we get the results.
