NCT00001003 ↗	A Study of Pentamidine in the Prevention of Pneumocystis Carinii Pneumonia	Completed	National Institute of Allergy and Infectious Diseases (NIAID)	N/A	1969-12-31	To evaluate and compare 3 anti-pneumocystis regimens plus zidovudine (AZT) in persons with advanced HIV disease and T4 cell count < 200 cells/mm3. To establish the range of pentamidine (PEN) deposition in AIDS patients participating in ACTG 021 and ACTG 081. To identify factors (breathing pattern, pulmonary function) that may be important in affecting the actual dose delivered to a given patient. The specific system that is used to deliver PEN to the lungs may determine whether a therapeutically effective dose is attained in the lungs. Therefore, this study will establish the amount of PEN that is deposited in the lungs of patients enrolled in protocols ACTG 021 and ACTG 081, who are being treated with PEN administered from the Marquest Respirgard II nebulizer.
NCT00001277 ↗	Studies of Elevated Parathyroid Activity	Completed	National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)		1993-12-15	Patients whose parathyroid activity is elevated above normal are referred to as having hyperparathyroidism. This study will help researchers better understand the causes of hyperthyroidism and to evaluate and improve methods for diagnosis and treatment. In this study, patients diagnosed with or suspected of having hyperparathyroidism will be selected to participate. In addition, patients with related conditions such as parathyroid tumors, will also be selected. Subjects will be asked to provide blood and urine for testing to confirm their condition. They will then be surgically treated by removal of the parathyroid gland(s) (parathyroidectomy). Subjects with parathyroid tumors will undergo several diagnostic tests to determine the exact location of the tumor as well as the tumor's activity. The tests may include; ultrasounds, nuclear scanning, CT scans, MRI, and specialized blood testing. Sometimes parathyroidectomy leads to hypoparathyroidism. Options for treating the patients after the surgical procedure will also be addressed. Calcium and Vitamin D supplements are typically the mainstay of post parathyroidectomy therapy. Other potential treatments include transplanting the parathyroid gland(s) to other areas of the body.
NCT00003654 ↗	Diagnostic Study to Identify Sentinel Lymph Nodes in Women With Stage I or Stage II Breast Cancer	Terminated	UNICANCER	N/A	1997-09-01	RATIONALE: Diagnostic procedures, such as blue dye or imaging to identify sentinel lymph nodes, may improve the ability to detect the extent of disease and help plan effective surgery for removing breast tumors. PURPOSE: Diagnostic trial to study the effectiveness of blue dye and an imaging procedure to identify the sentinel lymph node under the arm in women with stage I or stage II breast cancer.
