A Case of Acquired Methemoglobinemia Following Sentinel Lymph Node Dye With Patent Blue V.

Methemoglobinemia is a rare but potentially life-threatening condition in which hemoglobin is oxidized, impairing the oxygen-carrying capacity. While congenital forms exist, acquired methemoglobinemia can occur in perioperative settings, especially following exposure to oxidizing agents such as dyes used in sentinel lymph node biopsy (SLNB). Patent Blue V, a synthetic aniline dye commonly used for SLNB, has been associated with rare but serious adverse effects, including methemoglobinemia.

Distal transradial versus conventional transradial access in acute coronary syndrome.

Objective: Distal transradial access (TRA) has been recently introduced as an alternative access site for coronary angiography (CAG). Both procedures can be performed in cardiology clinics by interventional cardiologists. Although distal TRA is considered to be more difficult as it requires artery puncture and experienced cardiologists, it seems to be more advantageous because of the limited risk of arterial occlusion.

Mixture of Arginine, Glutamine, and β-hydroxy-β-methyl Butyrate Enhances the Healing of Ischemic Wounds in Rats.

Background: This study investigated the effects of an amino acid mixture containing arginine, glutamine, and β-hydroxy-β-methyl butyrate on secondary healing of ischemic wounds in a rat model (N = 18).

Methods: After the formation of a bipediculated flap on each rat, 2 full-thickness excisional skin wounds (2 × 2 cm) were created on every flap. The rats were then randomized into the control and treatment groups.

Pilot Experimental Study on the Effect of Arginine, Glutamine, and β-Hydroxy β-Methylbutyrate on Secondary Wound Healing.

Background: Wound healing is a complex process, dependent on available nutrition substrates. When used together with β-hydroxy β-methylbutyrate, arginine and glutamine have been shown to increase collagen deposition in human subjects. However, there are no experimental investigations on the influence of this amino acid mixture with regard to secondary wound healing.
