Fine needle aspiration biopsy of lymph nodes using a 19 gauge needle and Luer Lok syringe was performed in 59 cases. This was compared with histological diagnosis and an accuracy of 93.2% was achieved. This method is simple and is highly acceptable among patients. It is a very useful technique where a biopsy of lymph node is not possible (JPMA 30:267, 1980).

OBJECTIVES To assess the immunogenicity of vaccines for infants and to investigate whether the incidence of reactogenicity is reduced after each immunisation dose using needles of varying lengths and gauges. DESIGN Randomised controlled trial. SETTING 18 general practices within two UK primary care trusts. PARTICIPANTS 696 healthy infants vaccinated at 2, 3, and 4 months of age, with foll...

Iris cysts can arise from iris pigment epithelium or stroma. We present 3 cases of iris cysts which have been managed in different ways. In a one-month neonate, cyst was punctured with keratome and gentle diode laser endophotocoagulation was applied to the base. A2.5-month infant presented with watering and blepharospasm since birth. Clear fluid was aspirated from the cyst with a 27-gauge needl...

background and aims . dentists administer thousands of local anesthetic injections every day. injection to a highly vascular area such as pterygomandibular space during an inferior alveolar nerve block has a high risk of intravascular needle entrance. accidental intravascular injection of local anesthetic agent with vasoconstrictor may result in cardiovascular and central nervous system toxicit...

PURPOSE To describe an intravitreal injection technique using a commercially available 29-gauge insulin needle syringe (29GN syringe) and a 21-gauge (G) needle, comparing compound waste associated with this technique application and the one described in ranibizumab (Lucentis) kit instructions. METHODS Ten 0.3 ml doses of distilled water were aspirated using the 29GN syringe and 21G needle (PT...

BACKGROUND Zygomatic arch is a bony arch constituting the lateral midface, which consists of 25% of all midface fractures. There are a number of ways to evaluate the extent of zygomatic arch fracture. Some authors have reported successful treatment outcomes using ultrasound (U/S). To add to the previous methods, we have considered ways to accurately display the location of the fracture line whi...

Core needle biopsy is a safe procedure, with very few severe complications. The doctor administering the biopsy has to balance sample adequacy versus the complication rate when choosing which needle size to use. Larger needles produce better samples with fewer passes. However, larger needles also produce more bleeding in blood rich organs such as kidney or liver. We undertook this study because...
