Main Category: Fertility Also Included In: MRI / PET / Ultrasound Article Date: 07 Feb 2010 - 0:00 PST Men with no sperm in their ejaculate-a condition known as azoospermia- may no longer need invasive procedures to determine if they have sperm in their testes according to a new study published in Human Reproduction. Instead, the study found that MR Spectroscopy-a simple metabolic scan that combines the use of 1H Spectroscopy with magnetic resonance imaging (MRI)-can be used to determine the likelihood of finding sperm in men with non-obstructive azoospermia (NOA). The study's lead author is Paul Turek, MD, former professor and endowed chair at the University of California San Francisco and founder of The Turek Clinic. "Some men with azoospermia may still have small amounts of sperm in the testicle, but determining which of these men has retrievable sperm is challenging. This is a novel and exciting application of metabolic scanning that shows great potential to eliminate invasive biopsies and gives new hope to infertile men who wish to father children," said Dr. Turek, a men's reproductive health expert. Traditional methods for evaluating if sperm exist, including testicular biopsy and microdissection are highly invasive and have only a 60 percent to 65 percent success rate. FNA Sperm Mapping, pioneered by Dr. Turek, is far less invasive, but still involves the use of fine needle aspiration to obtain tissue samples from the testes. In contrast, MR Spectroscopy, or magnetic resonance spectroscopic imaging, is a non-invasive scan that measures metabolic activity in the testis. The study shows that the scan is as accurate as a more invasive testis biopsy in reading several abnormal patterns of sperm production typically associated with infertility and azoospermia. It also shows that testis tissue containing spermatids or sperm carry a distinct chemical signature that can be distinguished by MR Spectroscopy. Additionally, MR Spectroscopy has the ability to evaluate testis metabolism in as many as 100 areas within the testis, significantly increasing the ability to sample for sperm well beyond any of the more invasive techniques commonly used today. "Trust me when I say that men would rather have a non-invasive scan done than have a surgical procedure to determine whether or not they might be able to be fathers," says Dr. Turek. MR Spectroscopy is a non-invasive diagnostic technology that is cleared by the FDA.

Main Category: Ear, Nose and Throat Also Included In: Medical Devices / Diagnostics Article Date: 07 Feb 2010 - 0:00 PST Results of a clinical study presented Thursday, Feb. 4 at the annual Triological Society meetings in Orlando, Fla., suggest a sterile barrier sheath system has distinct advantages over germicidal immersion processes used to prevent contamination of fiberoptic nasopharyngolaryngoscopes (flexible ENT scopes). Flexible ENT scopes are used by otolaryngologists to examine the nose and throat area for various disorders such as dysphagia, reflux disease, snoring, and chronic sinusitis. Microbial study results show that sterile disposable sheaths, when used with endoscopes, are as effective as using a liquid germicidal system for disinfecting scopes between patient procedures and provide protection against cross-contamination equivalent to immersion in germicidal solutions. Study authors Alphi Elackattu, MD; Mary Zoccoli, MD; Jeffrey H. Spiegel, MD, FACS; and Kenneth M. Grundfast, MD, FACS, all from Boston University School of Medicine, note in their conclusion that through the use of sterile disposable sheaths, physicians will be able to prevent cross-contamination. Using the individually packaged disposable sterile sheaths has been cleared by the U.S. Food and Drug Administration as an acceptable alternative to high level disinfection following endoscope use. The Medtronic Slide-On™ EndoSheath® System is a sterile, disposable cover for flexible endoscopes that provides a latex-free barrier between the scope and the patient. The system is designed to reduce patient contact with organic debris and staff exposure to hazardous chemicals. The study authors noted that the system is an alternative to time-intensive chemical reprocessing, allows for quick scope turnaround and helps physicians maximize time treating patients. "The EndoSheath System is designed to allow physicians to cover the insertion tube of the flexible ENT scope with a sterile microbial barrier when performing endoscopy procedures in the clinic and office environments," said Janis Saunier, marketing director for the ENT division at Medtronic. "We believe the use of a sterile sheath on a nasopharyngoscope, combined with enzymatic detergent cleaning and disinfection with 70 percent alcohol, can provide a reliably decontaminated, patient-ready instrument, providing an acceptable alternative to high-level disinfection of endoscopes." About the ENT Business at Medtronic Located in Jacksonville, Florida, the Ear Nose and Throat (ENT) division at Medtronic develops and manufactures products designed to treat ENT diseases.
