We reviewed the subset of patients who underwent urgent surgery for tumor growth resulting in cardiopulmonary deterioration secondary to mediastinal compression precluding safe completion of 4 cisplatin-based chemotherapy cycles with rapidly declining serum tumor markers.\n\nResults: Five men (2.6%) with an average age of 25.8 years were identified. All patients initially presented with a large symptomatic anterior mediastinal mass and elevated serum tumor markers. Patients received an average of 2.4 chemotherapy cycles of a scheduled 4 courses before cardiopulmonary deterioration. Pathology
of the resected specimens demonstrated mature teratoma in all patients; however, it was admixed in 4 patients with foci of immaturity (n = 1), malignant transformation of teratoma to sarcoma (n = 2), and nonseminomatous germ cell tumor (n = 2). There was 1 operative
death. Three of the 4 operative survivors Selleckchem AZD1480 subsequently completed a total of 4 cycles of chemotherapy after recovery. Two patients are alive and well after an average of 14 years. Two patients died of metastatic selleck kinase inhibitor disease.\n\nConclusions: The growing teratoma syndrome should be defined not only as a growing mediastinal mass but also with secondary cardiopulmonary deterioration precluding safe completion of planned chemotherapy in the presence of declining serum tumor markers. Prompt recognition of this syndrome, discontinuation of chemotherapy, and surgical intervention can result in cure. (J Thorac Cardiovasc Surg 2012;144:438-43)”
“Suzuki-Miyaura cross-couplings of arenediazonium salts with arylboronic acids catalyzed by highly active aluminium hydroxide-supported palladium nanoparticles catalyst have been investigated for the first time. The reactions are performed at 25 degrees C in MeOH without any base and
ligand to afford biaryls in good to excellent yields under non-anhydrous and non-degassed conditions.”
“Objective: The purpose of the study was to compare bedside ultrasound (US) and panorex radiography in the diagnosis of AG-014699 chemical structure a dental abscess in emergency department (ED).\n\nMethods: A retrospective review of ED records of adult patients with atraumatic facial pain, swelling, and toothache who received a panorex x-ray and bedside US was performed. Medical records were reviewed for ED evaluation and disposition. Sensitivity and specificity of US and panorex x-ray were calculated to determine the clinical utility of the 2 tests.\n\nResults: A total of 19 patients were identified. No periapical abscess was reported on panorex x-rays in 7 (37%) of 19 patients. Ultrasound agreed with panorex x-rays in 6 (86%) of 7 cases. One case where US disagreed with x-rays was evaluated by dentistry consultants; and incision and drainage were performed, confirming the presence of an abscess. An x-ray diagnosis of periapical abscess was made in 12 (63%) of 19 patients.
