Background: Chlorhexidine is widely used as an antiseptic agent. It is a potentially allergenic substance that can cause severe hypersensitivity reactions.
Objective: We describe six patients who had anaphylactic reactions attributed to chlorhexidine during surgery. These patients were exposed to chlorhexidine in gels, swabs and catheters.
Materials And Methods: Six patients from three UK centres with clinical history suggestive of anaphylaxis during surgery are reported. Detailed history, review of case notes, determination of chlorhexidine specific IgE, mast cell tryptase and skin tests were performed.
Results: On detailed assessment five of six patients demonstrated a previous history of reactions on re-exposure to chlorhexidine. All six patients had elevated specific IgE to chlorhexidine. Skin prick test with chlorhexidine was performed in four of the six patients and was found to be positive.
Conclusion: Immediate hypersensitivity to chlorhexidine appears to be common but underreported in the UK. We recommend that centres investigating patients with reactions during anaesthesia and surgery should routinely include testing for chlorhexidine allergy.

Objective: To compare the rates of surgical site infection (SSI) after hysterectomy using vaginal antisepsis with chlorhexidine gluconate (CHG) versus povidone-iodine (PI).
Data Sources: PubMed, Embase, and Clinicaltrials.gov databases were queried from January 1, 1985 through Dec 7, 2023.

Urinary catheters are commonly used in medical practice to drain and monitor urine of patients. However, urinary catheterisation is associated with the risk of developing catheter-associated urinary tract infections (CAUTIs), which can result in life-threatening sepsis that requires antibiotics for treatment. Using the layer-by-layer (LbL) technique, we assembled a multilayer catheter comprising nine quadruple layers (9QL) of alginate, chlorhexidine (CHX), alginate and poly(β-amino ester) (PBAE) built upon an amino-functionalised silicone.

Background: Chronic and recurrent pyoderma in dogs is driving a growing interest in natural antimicrobial products that offer minimal adverse effects and avoid antibiotic resistance.
Objectives: Evaluate the safety and efficacy of dermatological products with antimicrobial peptides and plant extracts, comparing them to chlorhexidine + miconazole and cephalexin therapy for superficial pyoderma in dogs.
Materials And Methods: Forty-five dogs with superficial pyoderma underwent clinical, cytopathological and microbiological diagnosis, and were randomly assigned to Group 1 (G1) treated with shampoo (two weekly baths) and lotion (twice daily on the affected areas) containing natural antimicrobials; Group 2 (G2) treated with two weekly baths using a therapeutic shampoo containing 2% chlorhexidine and 2.

Background: New catheter materials for peripherally inserted central catheters (PICCs) may reduce the risk of device failure due to infectious, thrombotic, and catheter occlusion events. However, data from randomized trials comparing these catheters are lacking.
Methods: We conducted a randomized, controlled, superiority trial in three Australian tertiary hospitals.

Aim: To evaluate the effect of applying a matrix metalloproteinase (MMP) inhibitor on the fracture resistance of root-filled teeth restored with Everstick fiber-reinforced composite resin.
Subjects And Methods: After the selection of 60 freshly extracted human mandibular first molar, root canal access and standard uniformly sized mesio-occluso-distal (MOD) cavities were made and the teeth were randomly assigned into three groups ( = 20 each): Group I, the MOD cavity was first lined with flowable composite resin and then restored with composite resin. In Group II, Everstick fiber was placed into the bed of flowable composite in buccal-pulpal-lingual direction before the composite restoration was placed.
