PURPOSE To compare the effect of three different suturing techniques on astigmatism after deep anterior lamellar keratoplasty (DALK) in patients with keratoconus. METHODS In this retrospective study, 54 eyes of 54 patients with advanced keratoconus underwent DALK with three suturing techniques: single running, interrupted running, and combined interrupted and running. Postkeratoplasty astigma...

Monocular deprivation experiments can be used to distinguish between different ideas concerning properties of cortical synaptic plasticity. Monocular deprivation by lid suture causes a rapid disconnection of the deprived eye connected to cortical neurons whereas total inactivation of the deprived eye produces much less of an ocular dominance shift. In order to understand these results one needs...

introduction: laser surgery as an alternative for conventional surgical procedure has gained special attention. using carbon dioxide (co2) laser has some benefits like less post-operative pain, swelling and infection, decrease in risk of metastasis and edema, and less bleeding providing dry sites for surgery. case report: a 12 years old boy with lingual frenum with indication for excision was r...

PURPOSE To assess the effect of suture material, anchor orientation, and anchor eyelet design on the static loading properties of suture anchors. TYPE OF STUDY Biomechanical bench study. METHODS Two metallic suture anchors, Mitek GII (Mitek, Westwood, MA) and Corkscrew (Arthrex, Naples, FL) and a bioabsorbable anchor (Biocorkscrew; Arthrex) were tested with single strand of No. 2 Ethibond (...

PURPOSE To evaluate the influence of glutamine and obstructive jaundice on left colon healing in rats. METHODS Sixteen male rats were allocated across four groups: LG--Common bile duct ligation followed by colotomy and bowel suture on postoperative day 7. Supplementation with glutamine 2% from day 4 after duct ligation until euthanasia. L--Common bile duct ligation followed by colotomy and bo...

OBJECTIVE The goal of this study was to determine the cause of selected canine urolith formation using less conventional but more advanced analytical methods. METHODS A routine laboratory specialising in urinary calculi analysis noticed a special type of core zone in some canine uroliths, which was typically made up of cylindrical holes. Of 4028 canine samples analysed, non-absorbable suture ...

BACKGROUND Every surgical suture compresses the enclosed tissue with a tension that depends from the knotting force and the resistance of the tissue. The aim of this study was to identify the dynamic change of applied suture tension with regard to the tissue specific cutting reaction. METHODS In rabbits we placed single polypropylene sutures (3/0) in skin, muscle, liver, stomach and small int...

The patella is the largest sesamoid bone in the body. As the patella bone is responsible for the strong extensor mechanism of the knee joint, its reconstruction and anatomical restoration after fracture is always desirable over excision. Extra articular fracture of lower pole of patella accounts for less than 10 percent of all patellar fractures. The treatment of these fractures is complicated,...

OBJECTIVE To experimentally compare two classic techniques described for manual suture of the bronchial stump. METHODS We used organs of pigs, with isolated trachea and lungs, preserved by refrigeration. We dissected 30 bronchi, which were divided into three groups of ten bronchi each, of 3mm, 5mm, and 7mm, respectively. In each, we performed the suture with simple, separated, extramucosal st...

BACKGROUND AND OBJECTIVES Laparoscopic-assisted colectomy for colon and rectal cancer causes less surgical trauma than does open colectomy. However, current methods are more costly and require highly skilled staff. In addition, the technique for lymphadenectomy has yet to be standardized. We developed a technique that uses a nylon suture to elevate the colon. This method reduces costs without c...
