Helicobacter clarithromycin resistant (Yellow) Helicobacter clarithromycin sensitive (Green) HELICOBACTER PYLORI AND MACROLIDE RESISTANCE Rapid Identification from Biopsy Material (frozen and formalin fixed, paraffin-embedded sections) A One Hour Procedure Utilising Specific DNA Probes 1 Admiralty Way Camberley Surrey GU15 3DT United Kingdom Phone: +44 1276 600081 Fax: +44 1276 600151 E-mail: The recognition of the association between H. FISH is, pylori infection and peptic ulcers was a major breakthrough in gastroenterology. Reports • suggest that peptic ulcer is rare without either H. pylori or NSAID’s. It is present in almost all cases • Not susceptible to interference from other of duodenal ulcer and most cases of gastric ulcer. Histopathology is a sensitive, rapid and easy • method for diagnosis of H. pylori infection, however it does not provide information about the resistance pattern. Although culturing of H. • pylori enables the antimicrobial sensitivity pattern fixed, paraffin-embedded sections or direct of the organism to be determined, it is not widely used in routine laboratories because H. Pylori grows very slowly and requires strict conditions. Non-invasive clinical tests like the Urea breath test and serological methods are well established screening procedures which help to reduce the • Mixed populations of resistant and sensitive cost and workload of invasive endoscopy. However antimicrobial susceptibility testing of H. pylori obtained from gastric biopsies is essential • prior to the first therapy and after the first treatment failure, since Macrolide resistance in this pathogen is considered a main reason for BACTfish™ kits employ a patented procedure, failure of antibiotic eradication therapy. whereby the sample slides are fixed in a Unfortunately, phenotypic resistance testing in BACTwave™; a microwave based thermocycler, vitro is usually not available until 48—96 hours before treatment. Hybridisation is carried out in the BACTwave™ thermocycler, cycling between 46°C and 48°C. The cycling induces touch-down Resistance to Clarithromycin always correlates annealing which decreases turnaround time to 60 with a significant decrease in therapeutic efficiency minutes. predominantly by distinct point mutations within Product Details: the peptidyltransferase region of the 23S rRNA. Fluorescence In Situ Hybridisation (FISH) is a powerful technique that can be used to determine the presence of Helicobacter pylori in frozen or formalin-fixed, paraffin-embedded sections. Positive results from sections up to four years old have been reported. In addition FISH can also determine the resistance status to macrolides BACTwave™ Thermal Cycler from the same sample and at the same time. FISH can detect mixed populations of sensitive and resistant organisms and as it is based on A full catalogue of support reagents and materials whole cell hybridisation, maintains the cell is available upon request. DNA probes are structure for morphological studies. H. pylori can available as tandems or singly to allow method form coccoid, non-cultivable forms in vivo. FISH is customisation. able to identify these forms with the same



Over-the-Counter Medications in Pregnancy RONALD A. BLACK, M.D., and D. ASHLEY HILL, M.D. Florida Hospital Family Practice Residency, Orlando, Florida Pregnant women commonly use over-the-counter medications. Although most over- the-counter drugs have an excellent safety profile, some have unproven safety or are known to adversely affect the fetus. The safety profile of some medications ma
