Monopolar Suction Diathermy Adenoidectomy: Technical Note

Monopolar diathermy: 2 instruments, 1 hand.

Diathermy entails the implementation of high-frequency electrical currents to produce heat and either make incisions or induce coagulation. Monopolar cautery involves disposable cautery pencils and electrosurgical diathermy units. In typical monopolar cautery, an electrical plate is placed on the patient's skin and acts as an electrode, while the current passes between the instrument and the pl...

On Suction Gas Heating in Hermetic Compressors (A Technical Note)

Negative pressure suction technique for bone cement introduction into the delivery syringe. A technical note.

The authors present in this brief note a technique to facilitate the introduction of high viscosity bone cement into a cement syringe for retrograde high pressure cementing during total hip or revision knee arthroplasty. The nozzle part of the syringe is connected to the suction device used intra-operatively, to achieve a negative pressure in the syringe. Introduction of the cement into the syr...

Technical Note

We reported a new approach of ABO genotyping by a polymerase chain reaction and restriction fragment length polymorphism method. Instead of amplifying the loci containing the positions of nucleotides 258 and 700 of cDNA of the A transferase separately, we successfully amplified these 2 loci together in one reaction mixture using 2 sets of primers. The amplified DNA products were digested at the...

Technical note

Well known implementations for perspective correct rendering of planar polygons require a division per rendered pixel. Such a division is better to be avoided as it is an expensive operation in terms of silicon gates and clock cycles. In this paper we present a family of efficient midpoint algorithms that can be used to avoid division operators. These algorithms do not require more than a small...
