Efficacy of preoperative autologous blood storage in one-stage bilateral total knee arthroplasty.

Background: One-stage bilateral total knee arthroplasty (TKA) has the advantages of a single hospital stay, shorter rehabilitation, and reduced financial burden on patients. However, perioperative bleeding is greater with one-stage bilateral TKA than with unilateral TKA and is more likely to require allogeneic blood transfusion. At our hospital, we normally store autologous blood about 1 month before surgery to reduce the need for allogeneic blood transfusion and avoid its adverse reactions as much as possible.

Osteolytic primary bone lymphoma in the multiple bones.

Primary non-Hodgkin bone lymphoma (PBL) can involve solitary or multiple destructive bone lesions such as those of the femur or pelvis humerus, and some cases have osteolytic lesions. PBL is a rare disease in adults. Thus, PBL is rarely considered a differential diagnosis of the osteolytic tumor.

Transforaminal full-endoscopic lumbar discectomy under local anesthesia in awake and aware conditions: the inside-out and outside-in techniques.

Purpose Of The Review: Transforaminal full-endoscopic lumbar discectomy (TELD) under local anesthesia was first introduced in Japan in 2003. Initially referred to as percutaneous endoscopic discectomy, in 2018, a consensus was reached worldwide and the preferred term is now TELD. The procedure requires only an 8-mm skin incision and causes minimal damage to the paravertebral muscles.

c-Fos immunoreactivity of neural cells in intoxication due to high-dose methamphetamine.

Methamphetamine (METH) is a powerful and toxic psychostimulant that is abused worldwide. Although many studies of its toxic functions have been done on animals and humans, the mechanism is still poorly understood. In addition, the doses of METH examined have often been low.
