Primary Hyperparathyroidism in Patients with Multiple Endocrine Neoplasia Type 1: Experience by a Single Surgical Team in Japan

Nineteen patients were surgically treated for hyperparathyroidism associated with multiple endocrine neoplasia type 1 syndrome. Fourteen patients (74%) had removal of three or more parathyroid glands at the first operation, and five (26%) by removal of 2 1/2 or fewer glands. Two patients had recurrent hypercalcemia during the mean follow-up period of 65 months. One had a recurrence 10 years after subtotal parathyroidectomy. Reexploration in this patient revealed enlargement of the remaining tissue in the neck and an enlarged supernumerary gland in the aorticopulmonary window. The other patient had persistent hypercalcemia after removal of two hyperplastic parathyroid glands until after another 1 1/2 more glands were removed. After reoperation the patient was normocalcemic for 10 years before hypercalcemia was again noticed. The patient subsequently died from renal carcinoma metastases, which might have been the cause of the hypercalcemia before death

A case of late iliac arterial thrombosis due to component migration after revision total hip arthroplasty

AbstractAlthough vascular injuries associated with primary and revision total hip arthroplasty are infrequent, these complications can have devastating effects that can lead to morbidity and even mortality. A few previous reports have described embolic distal limb ischemia secondary to a failed and migrated acetabular implant in discontinuity with the pelvis. We present a rare case in which a support ring from a failed and migrated acetabular cage construct led to injury of the common femoral artery. The patient developed acute thrombotic occlusion leading to distal extremity ischemia even after oral anticoagulant therapy. The patient was treated with embolectomy with a Fogarty catheter, replacement of the injured common femoral artery with an InteRing 8mm, and removal of the offending hardware. Recognition of the risks associated with failed and migrated components is important to prevent this complication for cardiologists as well as orthopedic surgeons.<Learning objective: Although vascular injuries associated with primary and revision total hip arthroplasty are infrequent, these complications can have devastating effects that can lead to morbidity and even mortality.

IMPACT OF CORONARY ATHEROSCLEROSIS IN JAPANESE WOMEN WITH CHRONIC KIDNEY DISEASE

How do our brains transform the "blooming buzzing confusion" of daily experience into a coherent sense of self that can learn and selectively attend to important information? How do local signals at multiple processing stages, none of which has a global view of brain dynamics or behavioral outcomes, trigger learning at multiple synaptic sites when appropriate, and prevent learning when inappropriate, to achieve useful behavioral goals in a continually changing world? How does the brain allow synaptic plasticity at a remarkably rapid rate, as anyone who has gone to an exciting movie is readily aware, yet also protect useful memories from catastrophic forgetting? A neural model provides a unified answer by explaining and quantitatively simulating data about single cell biophysics and neurophysiology, laminar neuroanatomy, aggregate cell recordings (current-source densities, local field potentials), large-scale oscillations (beta, gamma), and spike-timing dependent plasticity, and functionally linking them all to cognitive information processing requirements.Air Force Office of Scientific Research (F49620-01-1-0397); National Science Foundation (SBE-0354378); Office of Naval Research (N00014-01-1-0624

Novel Charge Ordering in the Trimer Iridium Oxide BaIrO3

We have prepared polycrystalline samples of the trimer Ir oxide BaIrO3 with face-shared Ir3O12 trimers, and have investigated the origin of the phase transition at 182 K by measuring resistivity, thermopower, magnetization and synchrotron x-ray diffraction. We propose a possible electronic model and transition mechanism, starting from a localized electron picture on the basis of the Rietveld refinement. Within this model, BaIrO3 can be basically regarded as a Mott insulator, when the Ir3O12 trimer is identified to one pseudo-atom or one lattice site. The transition can be viewed as a transition from the Mott insulator phase to a kind of charge ordered insulator phase.Comment: 8 pages 5 figures, Crystals (in press

Coupling of Transmitting/Receiving Antennas and Super Regenerative Transponder (SRGT) for RFID Tags

Abstract-We propose the system of wireless IC tag that is fed with electromagnetic wave power and communicates with very weak radio wave. In this paper, we study the coupling the transmitting/receiving antennas with Super Regenerative circuit. Receiver sensitivity and transmitting electromagnetic field strength are clarified
