A 60-year-old woman presented with a neck mass and underwent fine needle aspiration of a left thyroid nodule. During this time, she had been injected with hCG for weight loss. Soon after, she developed rapid diffuse thyroid growth with pain. She was ultimately diagnosed with thyrotoxicosis due to postaspiration subacute thyroiditis and subsequently became hypothyroid. This condition is rare in ...

Prevalence of Polycystic Ovarian Syndrome(PCOS) in Iran is more than 6%. Therefore we encounter with many PCOS patients. In Vitro Maturation (IVM) of oocytes as an attractive method in ART is considered. Studies show that changes in culture conditions should be administered to make IVM protocol more successful .For this purpose in this study we have set up the beneficial cultures for IVM proced...

In situ imaging of alveoli and the smaller airways with optical coherence tomography (OCT) has significant potential in the assessment of lung disease. We present a minimally invasive imaging technique utilizing an OCT needle probe. The side-facing needle probe comprises miniaturized focusing optics consisting of no-core and GRIN fiber encased within a 23-gauge needle. 3D-OCT volumetric data se...

The 'dry-needle technique', an intramuscular stimulation technique carried out by using a fine solid, 1-inch long, 30-gauge needle, was investigated in the treatment of tension-type headache (TTH) in a randomized, placebo-controlled trial. Fifteen patients with TTH received intramuscular needle insertions into six designated trigger points, while 15 controls received subcutaneous insertions. He...

During knee arthroscopy, narrowness and tightness maybe encountered in the medial compartment that does not allow sufficient visualization or instrumentation. When this occurs, our team has found it helpful to perform a percutaneous clysis of the deep portion of the medial collateral ligament with a spinal needle. With the knee positioned in 10° to 20° of flexion and a valgus stress is applied....

PURPOSE The traditional method of percutaneous renal access requires freehand needle placement guided by C-arm fluoroscopy, ultrasonography, or computerized tomography. This approach provides limited objective means for verifying successful access. We developed an impedance based percutaneous Smart Needle system and successfully used it to confirm collecting system access in ex vivo porcine kid...

Using testicular spermatozoa from either open biopsy (29 cycles) or biopty gun needle biopsy (49 cycles), a total of 81 intracytoplasmic sperm injection (ICSI) cycles among 57 couples were carried out from January, 1994 to September, 1997. In six cycles, no spermatozoa were obtained, and in three cycles spermatozoa from both needle and open biopsies were used. The fertilization (37% after open ...

Introduction: The phenomenon of neglected foreign bodies is a significant cause of morbidity in soft tissue injuries and may present to dermatologists as delayed wound healing, localized cellulitis and inflammation, abscess formation, or foreign body sensation. Localization and removal of neglected soft tissue foreign bodies (STFBs) is complex due to possible inflammation, indurations, granulat...
