A Rare Case of Extra-Nodal Rosai-Dorfman Disease of the Cheek.

Rosai-Dorfman disease (RDD), which was first reported by Rosai and Dorfman in 1969, is a rare, benign, non-neoplastic proliferation of histiocytes, characterized by painless lymphadenopathy and fever. Lymphadenopathy occurs most commonly in the neck, but also appears in non-cervical lymph nodes or as extranodal lesions. In this case, biopsy of an atypical subcutaneous buccal mass, which was difficult to diagnose preoperatively, led to a diagnosis of RDD.

Lumbar Sympathetic Ganglion Block Facilitates Wound Healing in a Rat Ischemic Hindquarter Model.

Unlabelled: Lumbar sympathetic nerve block (LSNB) improves blood flow in the lower limbs and relieves pain involving the sympathetic afferents. This study examines the use of LSNB, but there are no reports of its use for the purpose of wound healing. Therefore, the authors planned the following study.

The effect of Shoseiryuto, a traditional Japanese medicine, on cytochrome P450s, N-acetyltransferase 2 and xanthine oxidase, in extensive or intermediate metabolizers of CYP2D6.

Objective: Shoseiryuto (TJ-19) contains eight herbal components, including Ephedra sinica, and has been used for treating asthma and allergic rhinitis in Asian countries for several centuries. In this study, we investigated the potential herb-drug interaction of TJ-19 in healthy volunteers and attempted to ascertain whether or not the interaction might be affected by the cytochrome P450 (CYP) 2D6 genotype.

Methods: We assessed the effect of TJ-19 on the activities of CYP1A2, CYP2D6, CYP3A, xanthine oxidase (XO), and N-acetyltransferase 2 (NAT2) in 37 healthy subjects.
