Using 11C-Pittsburgh compound B (PiB)-PET and MRI volume data, we investigated whether white matter (WM) PiB uptake in Alzheimer's disease (AD) brain is larger than that of cortical PiB uptake-negative (PiB-negative) brain. Forty-five subjects who underwent both PiB-PET and MRI were included in the study (32 AD patients with cortical PiB-positive and 13 cortical amyloid -negative patients). ⋯ Frontal WM SUVR in the AD group vs frontal WM SUVR in the PiB-negative group was 2.57 ± 0.55 vs 1.64 ± 0.22; parietal, 2.50 ± 0.52 vs 1.74 ± 0.22; posterior cingulate, 2.84 ± 0.59 vs 1.73 ± 0.22; and WM in the centrum semiovale, 2.21 ± 0.53 vs 2.42 ± 0.36, respectively. We found that PiB uptake in AD brain is significantly larger than that in PiB-negative brain in the frontal, parietal and posterior cingulate subcortical WM, except in the centrum semiovale.

This prospective study clarified changes in the mood states of Japanese patients with implantable cardioverter defibrillators as well as factors related to the mood states. Using a longitudinal repeated-measure design, 29 patients with implantable cardioverter defibrillators completed the Profile of Mood States-Short Form Japanese Version questionnaire before discharge and 1, 4, 7, and 13 months after implantation. ⋯ No relationship with defibrillation experience was detected in this study, but employment, age, sex, and lack of experience of syncopal attack were factors related to poor mood states for patients with implantable cardioverter defibrillators. Therefore, Japanese patients with implantable cardioverter defibrillators with any factor deteriorating their mood state should be monitored so that their mood state does not deteriorate again between six months and one year after implantation.

Atypical polypoid adenomyoma (APA) is a rare polypoid tumor of the uterus composed of atypical endometrial glands and smooth muscle cells. Concomitant development of endometrial adenocarcinoma in APA remains infrequent. We report a case of the coexistence of endometrioid adenocarcinoma in APA. ⋯ No residual malignant lesions were found. Awareness of the close association of APA with the development of endometrial cancer is warranted. A meticulous pathological evaluation of specimen of APA is necessary for the detection of the coexistence of endometrial cancer.

Amyloidosis is a relatively rare disease that may be underdiagnosed and could affect the entire human body. Many organs may be affected, which could increase the morbidity and mortality. Cardiac involvement is the leading cause of poor prognosis. ⋯ In the present case, DFS and HE were used, both of which suggested amyloid deposits surrounding myocardial cells. The use of a combination of stains can increase the diagnostic sensitivity and specificity of amyloidosis. However, the typical echocardiographic appearances would be enough to diagnose cardiac amyloidosis when it is impossible for the patient to undergo a cardiac biopsy, if an additional histological specimen from another tissue such as abdominal fat confirms amyloidosis.

Severe laceration of flexor tendons after locking palmar plate fixation of distal radius fracture: a case report.
We report a case of flexor pollicis longus and flexor digitorum profundus(II) laceration as a result of the severe tenosynovitis after volar locking plate fixation of distal radius fracture.
