the pathergy phenomenon (pp) is one of the hallmarks of behcet's disease (bd). it has been reported to be positive from 17.5% to 83% of cases in different studies. pp is used as a diagnosis criterion in the dilsen criteria, the japan criteria, the international criteria, and the iran criteria. it is therefore important to know wether pp is a fix manifestation of the disease or a cyclic manifest...

PURPOSE The purpose of this survey is to evaluate current usage of local and topical anesthesia by Pediatric Dentist to evaluate the current practices. METHODS Surveys were sent to 3051 pediatric dentists asking about types of anesthetics, considerations in determining local anesthetic dosage, time used to inject a cartridge and shortcomings of topical preparations. Data were computed for per...

OBJECTIVE The study was designed to compare the insertion characteristics and incidence of PDPH between 25 gauge Quincke needle and 26 gauge Eldor needle for spinal anaesthesia in elective c/s. METHOD 60 pregnant women (aged 19-35 yrs and weighing 58 -67 kg) undergoing elective caesarean section were randomized into group A (Quincke spinal needle group) or group B (Eldor spinal needle group)....

Objective – To measure blood aqueous-barrier breakdown following aqueocentesis using various needle sizes and to monitor the intraocular pressure (IOP) response. Animals – 24 healthy, adult dogs received treatment (24 treated eyes, 24 contralateral eyes); 3 dogs were untreated controls (6 control eyes). Procedures – Dogs receiving treatment were divided into 3 equal groups (25-, 27-, or 30gauge...

Thirty-gauge needles are generally not recommended by dental schools, yet many dentists use them. Thin needles (30 gauge) can aspirate blood, have similar deflection to thick needles (25 gauge), and resist breakage. Measurable clinical differences between inferior dental block injections using 25-gauge or 30-gauge short needles for children is addressed in this research paper. Random allocation...

background: the purpose of this study was to evaluate the results of stereotactic breast core needle biopsy in a tertiary breast center of tehran university of medical sciences. methods: patients who were candidates for mammography-guided stereotactic breast core biopsy from march 2011 to december 2013 were included in this study. stereotactic biopsy was performed by a dedicated prone hologic m...

We introduce a 15 cm, 26-gauge spinal needle (Steriseal Ltd, Redditch) through a standard Tuohy needle (9·6 cm, 16-gauge) which has its tip in the epidural space. Once the dura has been punctured the spinal needle is only really held in place by the dura. It is therefore quite difficult to attach the syringe of local anaesthetic and then inject without inadvertently placing the tip of the spina...

OBJECTIVES The purpose of this study is to determine the possible differences in deflection between two needles of same length and external gauge but with different internal gauges during truncal block of the inferior alveolar nerve. The initial working hypothesis was that greater deflection may be expected with larger internal gauge needles. STUDY DESIGN Four clinicians subjected 346 patient...

OBJECTIVES To compare the frequency of headache and the procedure time following lumbar puncture (LP) using a 25-gauge needle compared to a 22-gauge needle. DESIGN 4-period crossover blinded randomised controlled trial. SETTING Oncology unit, Royal Children's Hospital, Melbourne. PATIENTS Children aged 4-15 years at enrolment having LPs as part of their treatment for leukaemia. INTERVEN...
