Concept: Creativity techniques
The aim of this study was to compare two different thermoplastic techniques-a core-carrier technique (Thermafil) and warm vertical compaction-in terms of overextension of root canal filling in vivo.
The temperature and the speed of drying may affect the quality of the end product of medicinal plants. In addition, ecotypes and chemotypes could be factors influencing this quality. Thus, the aim of our study was to explore various techniques of drying of Origanum syriacum L., which is considered as a main ingredient in the Lebanese diet. For all these reasons, we decided to study two types of O. syriacum originating from Rkai and Ibrine regions on which analyses were carried out. In view of our results, a moderate temperature, in the absence of light, is more favourable for the safeguarding of the flavours and chlorophylls. On the other hand, these conditions seem to be unsuitable for other substances. In order to clarify the optimal conditions for drying of O. syriacum to lead to a product of quality, the choice of a technique of suitable dehydration seems to be delicate.
Obstructive azoospermia secondary to epididymal obstruction can be corrected by microsurgical reconstruction with vasoepididymostomy (VE). Although alternative management such as epididymal or testicular sperm aspiration in conjunction with intracytoplasmic sperm injection is feasible, various studies have established the superior cost-effectiveness of VE as a treatment of choice. Microsurgical VE is considered one of the most technically challenging microsurgeries. Its success rate is highly dependent on the skills and experience of the surgeons. Various techniques have been described in the literature for VE. We have pioneered a technique known as longitudinal intussusception VE (LIVE) in which the epididymal tubule is opened longitudinally to obtain a larger opening to allow its tubular content to pass through the anastomosis. Our preliminary data demonstrated a patency rate of over 90%. This technique has been widely referenced in the recent literature including robotic-assisted microsurgery. The history of the development of different VE approaches, the preoperative evaluation along with the techniques of various VE will be described in this article.Asian Journal of Andrology advance online publication, 19 November 2012; doi:10.1038/aja.2012.80.

Proximal and distal (mid-thigh) ultrasound-guided continuous adductor canal block techniques have been described but not yet compared, and infusion benefits or side effects may be determined by catheter location. We hypothesized that proximal placement will result in faster onset of saphenous nerve anesthesia, without additional motor block, compared to a distal technique.

Zipper injuries are highly distressing to patients and often difficult to manage. Several management techniques are described in the literature. Many are complex and laborious, requiring sophisticated instruments in skilled hands, or even rely on a formal operation. This new technique involves the release of entrapped penile skin from a zipper by cutting the zipper tape and teeth immediately superior and inferior to the zipper connector and using a needle holder to pull the zipper apparatus apart following the application of lubrication and appropriate use of local analgesia. This novel technique is quick, nontraumatic and requires readily available equipment. It has been used successfully in two patients who were ineligible for a circumcision.
Buttonhole cannulation was introduced into this Queensland Renal Service in 2005. Contrary to published literature, a local review of cannulation outcomes found no greater likelihood of infections with the buttonhole technique.
The difficulty in correcting deviated nose has been discussed for more than 50 years. Numerous techniques have been proposed for the rectification of this deformity. In this study, we describe a modification to the extracorporeal septoplasty technique that comprises a more conservative approach and results in a stable cartilaginous framework. Combination of curved spreader graft with a septal caudal graft is introduced in the method as a modified extracorporeal septoplasty. Twenty-three patients were enrolled in the study. There were no revision cases. In all cases, comparison of preoperative and postoperative photographs showed improved contour.
No consensus exists concerning the acceptable ranges of marginal fit for lithium disilicate crowns fabricated with either heat-pressing techniques or computer-aided design and computer-aided manufacturing (CAD/CAM) systems.
Nonunions of the upper extremity are a source of significant morbidity and can be difficult to treat. This paper describes a sliding bone graft technique that offers several significant advantages over other techniques for nonunions.
The aim of this retrospective study was to evaluate the results obtained in 353 dogs (420 eyes) using two different surgical techniques for correction of a prolapsed gland of the third eyelid: the Morgan’s pocket technique and a technique combining Morgan’s approach with a slightly modified periosteal anchoring technique of Stanley and Kaswan. The pocket technique was used in 234 eyes and the combined technique in 186 eyes. Successful repositioning was obtained in 95% of all cases, with recurrence occurring in 5%. The recurrence rate in large breed dogs such as the English Bulldog and Boxer was lower with the combined technique than with the pocket technique.
