Is bypass graft technique effective in arteriovenous graft?

Background: Arteriovenous graft (AVG) requires percutaneous transluminal angioplasty (PTA) to maintain its patency; however, bypass graft technique is often chosen in cases requiring PTA again within 3 months. We retrospectively examined whether bypass graft technique is effective for AVG.

Methods: The sample patient population consisted of 50 patients who underwent bypass graft technique on the venous side of the AVG between April 2012 and March 2014.

The participation of adenosine receptors in the adenosine 5'-triphosphate-induced relaxation in the isolated rabbit corpus cavernosum penis.

Aim: To investigate the participation of adenosine receptors in the adenosine 5'-triphosphate (ATP)-induced relaxation in the corpus cavernosum penis (CCP) of rabbits.

Methods: The ATP-induced relaxation was assessed on the noradrenaline precontracted CCP of rabbits in the presence and absence of 8-(3-chlorostyryl)caffeine (CSC); an adenosine A(2A) receptor antagonist; alloxazine and MRS1754; adenosine A(2B) receptor antagonists; and ARL67156, an inhibitor of ecto-nucleoside triphosphate diphosphohydrolases.

Results: Adenosine and ATP relaxed the noradrenaline precontracted CCP of rabbits in a concentration-dependent manner.

Cushing syndrome associated with prostatic tumor adrenocorticotropic hormone (ACTH) expression after maximal androgen blockade therapy.

We report a patient with adenocarcinoma of the prostate, who eventually developed Cushing syndrome due to ectopic adrenocorticotropic hormone (ACTH) secretion from the tumor. At first, maximal androgen blockade (MAB) therapy was effective for the prostate carcinoma, which was positive for prostate-specific antigen (PSA) and negative for ACTH on the biopsy specimen. However, 3 years later, the patient complained of bilateral leg edema.
