Results: Subepithelial tissue was acquired in 97â€Š% (static jaw FB-11K-1), 93â€Š% (static jaw FB-45Q-1), 80â€Š% (alligator jaw), and 55â€Š% (large-capacity) of samples.

One pathologist calculated the surface area of epithelial and subepithelial layers in hematoxylin and eosin (H&E)-stained biopsies. Biopsies sampled from distal esophagus using a static jaw forceps (Olympus, FB-11K-1) were compared with proximal biopsies sampled with static jaw (Olympus, FB-45Q-1), alligator jaw (Olympus, FB-210K), and large-capacity forceps (Boston Scientific, Radial Jaw 4). Patients and methods: In this cross-sectional study, esophageal biopsies were taken in 30 adult patients by one expert endoscopist. This study aimed to evaluate the efficacy and safety of deep esophageal sampling with four different types of biopsy forceps. Unlike superficial inflammatory changes, subepithelial fibrosis is not routinely sampled in esophageal biopsies. Survival was.Ĭomparison of different biopsy forceps models for tissue sampling in eosinophilic esophagitis.īussmann, Christian Schoepfer, Alain M Safroneeva, Ekaterina Haas, Nadine Godat, SÃ©bastien Sempoux, Christine Simon, Hans-Uwe Straumann, Alexīackground and aims: Eosinophilic esophagitis (EoE) is a mixed inflammatory and fibrostenotic disease. We describe a simple technique for obtaining such samples from unionacean bivalves and how we compared survival among biopsied and control organisms in field experiments. Mantle biopsy is a means of obtaining tissue samples for genetic, physiological, and contaminant studies of bivalves but the effects of this biopsy on survival have not been determined. Mantle biopsy: a technique for nondestructive tissue-sampling of freshwater musselsĭavid J. Paired swab and biopsy samples are a suitable representative sample of allograft musculoskeletal tissue for bioburden testing.

Skin commensals were the most common group of organisms isolated during a 12-year retrospective review of paired swab and biopsy samples from living donor allograft femoral heads. Low numbers of challenge organisms were recovered from inoculated swab and biopsy samples in the in vitro study and validated their use for bioburden testing of allograft musculoskeletal tissue. From the 3,859 donor episodes received, 21 paired swab and biopsy samples each recovered an isolate, 247 swab samples only and 79 biopsy samples only were culture positive. Samples of allograft femoral heads were collected from living donors during hip operations.

A retrospective review of donor episodes was also performed, consisting of paired swab and biopsy samples received in this laboratory during the period 2001-2012. On average, 8.4 to >100 and 7.2 to >100Â % of the inoculum was recovered from swab and biopsy samples respectively. An in vitro study was performed using the National Committee for Clinical Laboratory Standards standard 'Quality control of microbiological transport systems' (2003) to validate and evaluate the recovery of six challenge organisms from swab and biopsy samples of allograft musculoskeletal tissue. Swab and biopsy samples of allograft musculoskeletal tissue are most commonly collected by tissue banks for bacterial and fungal bioburden testing.
