Filter by:The effectiveness of antimicrobial prophylaxis (AMP) for prevention of surgical site infection (SSI) following thyroid and parathyroid surgery remains uncertain. Present prospective randomized control study (Ito-RCT1) assessed the effectiveness of AMP in clean neck surgery associated with thyroid and parathyroid disease.
This study is a randomized, double-blind, active controlled phase 3 trial in the patients with thyroid disease, who will undergo total thyroidectomy (excluding the patients with the patient with the past history of thyroid surgery). An eligible patient will be randomized and allocated to either the test group (Hyalobarrier) or active-comparator group (Guardix-SG). He/she will undergo marshmallow esophagography in detecting esophageal dysmotility at 6 weeks after study intervention and will be followed for 12weeks. During the study, both the patients and the observer for the primary and secondary efficacy evaluation will be masked. Non-inferiority of the test device (Hyalobarrier) compared to the reference device (Guardix-SG) will be confirmed using the primary efficacy outcome,the percentage of normal esophageal transit.
The goal of this study is to help better determine the complication rates for endocrine surgery across the nation for both benign and malignant disease. It is our hypothesis that the complication rates are low overall and that malignant disease results in a higher complication rate than benign disease. This study will do a database review from all University HealthSystem Consortium (UHC).
Comparing the effectiveness of subconjunctival and peribulbar Triamcinolone injection to systemic Steroid therapy for patients with active thyroid orbitopathy.
The purpose of this study is to determine whether treatment of thyroid disease during pregnancy decrease the incidence of adverse outcome, and to compare the impact of Universal Screening versus case Finding strategy in detecting thyroid dysfunction
This study intends to examine how a common genetic pattern affects thyroid function. Recent studies have demonstrated that a substance (enzyme) produced by a gene has an important role in controlling circulating thyroid hormone levels. A commonly found pattern in this gene exists in many individuals and might affect the function of the enzyme. These individuals need higher doses of thyroid hormone medication in certain situations (e.g. in the treatment of thyroid cancer after the thyroid gland has been removed) than those individuals without the variation. We intend to study this by looking at the response to a hormone-test in healthy volunteers with different genetic patterns. We plan to screen healthy volunteers using a blood test to identify their genetic pattern relating to the enzyme we are interested in. From this group, forty-five healthy volunteers will be recruited for the hormone-test. This test (called the TRH test) uses a hormone produced by the brain and stimulates the pituitary and thyroid gland. The response to this test will allow us to compare the function of the thyroid system in relation to the genetic pattern of the volunteer. We hypothesize that the stimulation of the thyroid hormone system will be decreased in volunteers with a specific genetic pattern and that these individuals will release less active thyroid hormone from the thyroid gland in response to the TRH test. This study will provide new information on the effect of a common genetic pattern on thyroid hormone function and will help us to better understand the way in which the thyroid hormone system operates. Ultimately, the results of this study might help to provide a more individualized therapy for patients in need of thyroid hormone replacement.
Thyroid disease is more common among females and is increasing in incidence. Otolaryngology faculty members and residents will perform head and neck examinations as part of the subject's routine care. If the participant is noted to have thyroid disease, they will be asked if they would like to participate in the research portion by having approximately 10cc's of blood drawn. Faculty and staff will complete a data collection sheet that will contain demographic and clinical data.
This study will determine the safety and activity of a new formulation of thyrotropin-releasing hormone (TRH), a drug used for diagnosing and evaluating patients with certain thyroid gland abnormalities. Normal thyroid gland function depends on proper chemical signaling between the thyroid gland, the hypothalamus (the part of the brain where TRH is made), and the pituitary (another part of the brain). The TRH test helps assess this interaction. Production of the only FDA-approved preparation of TRH was stopped in July 2002. As a result, to have a continuous source of TRH available for NIH clinical and research purposes, the NIH Clinical Center (CC) Pharmacy Department produced a pharmaceutical grade formulation of TRH for patient use. This study will test the CC formulation in healthy volunteers to show that its activity and side effects are similar to those of the previously available commercial test preparation. It will then be studied in CC patients for whom the diagnostic test is recommended. Healthy volunteers between 18 and 65 years of age and all patients requiring TRH evaluation of hypothalamic-pituitary-thyroid gland interaction may be eligible for this study. Patients include those with pituitary reserve, inconsistent thyroid function test, inappropriate TSH secretion, or pre- and post-operative evaluation of pituitary tumors. Normal volunteers will be screened with a medical history, physical examination, and blood tests. Women of child-bearing potential will be given a pregnancy test; pregnant and breast-feeding women may not participate. The TRH test procedure will be the same for healthy volunteers and patients. All participants fast from midnight before the morning of the test. In the morning, a catheter (flexible plastic tube) is inserted into an arm vein for easy injection of the TRH and collection of blood samples. Blood pressure is monitored before and during the test. A blood sample is drawn, and then TRH is given through the catheter over a 1-minute period. Another nine blood samples are collected over a 3-hour period from the time of the TRH injection for measuring levels of various hormones. A total of less than 4 tablespoons of blood is taken for the test.
