We report a case of spontaneous coronary artery dissection located next to a myocardial bridge in a patient with concomitant takotsubo cardiomyopathy. A fusion image with multidetector-row computed tomography and single-photon emission computed tomography played an important role in the diagnosis of these lesions.

Objective Persistent renal damage (RD) three months after exposure to contrast media is associated with contrast-induced acute kidney injury (CI-AKI) and poor clinical outcomes. Little is known about the role of preprocedural hydration on persistent RD in patients with chronic kidney disease [CKD; estimated glomerular filtration rate (eGFR)

VF event detected by CRTD, but thoracic impedance increased remarkably higher before and during syncope. After withdrawal of diuretics, his symptoms disappeared and thoracic impedance decreased to the former level. Conclusion: It is not easy to recognize adequate volume for each patient, especially on dry side. This is the first case report showing that thoracic impedance may be useful for detecting not only wet side, but also dry side. Further study is required to evaluate thoracic impedance value in detecting hypovolemia.

Concentrations of free amino acids were measured in the temporal cortex of postmortem brains from four histologically verified cases with Alzheimer-type dementia (ATD) and eight histologically normal controls. The concentrations of taurine, glutamate, and gamma-aminobutyric acid, which are all neurotransmitter candidates, were significantly lower in the ATD brains than in the controls. These findings suggest that the involvement of amino acid neurons in ATD cannot be ruled out.
