This study aims to compare the differences in sampling satisfaction rates between 5 mL syringe and 22G percutaneous transhepatic cholangiography (PTC) needles fine-needle aspiration (FNA) provide economical reasonable needle selection. From January 2021 March 2022, 187 patients with thyroid nodules (a total of 200 nodules) who underwent ultrasound-guided FNA were punctured using PTC once for ea...

Aims: In most countries, the spread of HIV and hepatitis C in prisons is clearly driven by injecting drug use with many infected prisoners who are unaware of their infection status. Despite many studies confirming the facts about risk behaviour and the prison setting as a risk environment for maintaining or taking up of risk behaviour, little progress has been made around effective and efficien...

BACKGROUND Pain and needle-phobia can be a problem during the application of local anesthesia with syringe and needle. OBJECTIVE To evaluate a jet-injection device (without needle) to deliver local anesthesia. METHODS Two hundred and six minor dermatological procedures using a jet-injection device for administering local anesthesia into skin tissue were performed. We comment on the technica...

The instrument described here consists of a special syringe on which sharp cutting needles of various sizes are mounted. These produce undistorted biopsy specimens. Suction is used only to retain the specimen within the needle, and the cleancut cylinder of tissue is quite unlike that obtained by aspiration. Gillman and Gillman&2 used this principle for their liver biopsy instrument. We have ret...

The purpose of this study was to compare daily changes in the concentration of atropine or ephedrine sulfate solutions that had been stored up to 4 days in plastic or glass syringes. Sets of three plastic and one glass syringe were used for each drug; the glass syringes acted as controls. Each set of syringes was labeled as day 0, 1, 2, 3, or 4. Syringes with medication were laid horizontally, ...

The spread of HIV infection into leishmaniasis endemic areas has increased the incidence of immunosupressed patients with kalaazar in Portugal. The dermotropic zymodeme MON-24 of leishmania infantum has been already isolated from a Portuguese AIDS patient, as in some other Mediterranean countries. In this paper we report the isolation of L. donovani MON-18 from a drug addicted Portuguese patien...

We describe a simple and feasible procedure for performing intravenous administration of substances in the gerbil. Under light anaesthesia, animals were held in dorsal recumbency and a very small incision of skin, parallel to the femoral vein on the internal side of the thigh, was made. The vein is easily accessible via thin skin incision. An insulin syringe and a 30 G needle were used for the ...

BACKGROUND Digital nerve block is commonly performed by care providers in medical fields. This study compares the blocks in terms of effectiveness of anesthesia and pain. METHODS Patients were divided into two groups. First group underwent digital block whereas 2nd group had transmetacarpal digital block. The subcutaneous ring block was performed by two injections of 3 ml of 2% lignoca...
