To familiarise surgical teams with the intraoperative use of the 'Fluobeam(TM)' device (Fluoptics).\n2. To understand the patterns (onset, intensity and duration) of fluorescent staining of normal parathyroid glands, thyroid glands and other soft tissue structures encountered during parathyroidectomy.\n\nFurther research:\n\nThis will be followed by a phase II study during which fluorescent imaging will be used in conjunction with intraoperative incremental dose of IV methylene blue in both thyroid and parathyroid surgery. Phase II will enable us to develop a protocol for the use of a minimum possible dose of MB for the identification of parathyroid glands. This will then be tested in the pilot phase of a randomized clinical trial.", 'detailedDescription': 'As above'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* all patients undergoing parathyroid surgery\n\nExclusion Criteria:\n\n* patients undergoing re-do procedures\n* patients unable to give adequate informed consent\n* patients with a history of intolerance or sensitivity to MB\n* patients with G6PD deficiency\n* patients on serotonin reuptake inhibitors and patients undergoing thoracic exploration\n* either alone or in combination with a neck exploration.'}, 'identificationModule': {'nctId': 'NCT01598727', 'briefTitle': 'Near Infrared Fluorescent Imaging in Thyroid and Parathyroid Surgery With the Fluobeam(TM) System of Fluoptics', 'organization': {'class': 'OTHER', 'fullName': 'Sheffield Teaching Hospitals NHS Foundation Trust'}, 'officialTitle': 'A Phase I Feasibility Study of Intra-operative Near Infra-red Fluorescent Imaging in Thyroid/Parathyroid Surgery With the Fluobeam(TM) System of Fluoptics', 'orgStudyIdInfo': {'id': 'STH16019'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'EXPERIMENTAL', 'label': 'Fluobeam(TM) Imaging System (Fluoptics)', 'description': 'Single arm observational pilot study', 'interventionNames': ['Device: Fluobeam(TM) Imaging System (Fluoptics)']}], 'interventions': [{'name': 'Fluobeam(TM) Imaging System (Fluoptics)', 'type': 'DEVICE', 'description': "Use of 'Fluobeam(TM)' (Fluoptics) as an intraoperative real time fluorescence detection system during surgery", 'armGroupLabels': ['Fluobeam(TM) Imaging System (Fluoptics)']}]}, 'contactsLocationsModule': {'locations': [{'zip': 'S10 2JF', 'city': 'Sheffield', 'state': 'South Yorkshire', 'country': 'United Kingdom', 'facility': 'Department of General Surgery', 'geoPoint': {'lat': 53.38297, 'lon': -1.4659}}], 'overallOfficials': [{'name': 'Saba P Balasubramanian, PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'University of Sheffield'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'Sheffield Teaching Hospitals NHS Foundation Trust', 'class': 'OTHER'}, 'collaborators': [{'name': 'Fluoptics Ltd, Grenoble, France', 'class': 'UNKNOWN'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
