Acute double flexor tendon ruptures following injection of collagenase clostridium histolyticum (Xiapex) for Dupuytren's contracture

Abstract: We report a case of acute (24 h) double flexor tendon rupture of the little finger after a single injection of collagenase clostridium histolyticum into a palmar Dupuytren's contracture cord which caused metacarpophalangeal joint contracture. Tendon surgery was performed 48 h postinjury with primary repair and standard rehabilitation but it resulted in poor active flexion due to adhesions. Previous papers have suggested that a needle inserted into the flexor tendon can be detected prior to the injection of collagenase by asking the patient to actively move the finger, but our test on an awake patient showed that when a 27-gauge needle was inserted into the flexor tendons through a thick palmar cord, the syringe did not move significantly when the patient moved the finger, and therefore this test does not minimise the risk of iatrogenic tendon injury when using collagenase (Xiapex) for Dupuytren's contracture.

Fluoroscopy-free cryoablation of atrial fibrillation guided solely by transoesophageal echocardiography: a case report.

Abstract: Background Atrial fibrillation (AF) ablation has been shown to be possible using minimal or no fluoroscopic imaging for guidance. However, the techniques previously described focus on radiofrequency ablation or rely on the use of resource-heavy technology such as intra-cardiac echocardiography. We describe the first reported case in the literature of successful fluoroscopy-free AF cryoablation guided solely by transoesophageal echocardiography (TOE). Case summary A 65-year-old gentleman underwent cryoablation of paroxysmal AF using TOE guidance only with no use of fluoroscopy. Transoesophageal echocardiography was used in all stages of the procedure including guidance for transseptal puncture, ensuring balloon position in the pulmonary veins, and checking for post-procedure pericardial effusion. After 5 months of follow-up, the patient remains in sinus rhythm and has discontinued all antiarrhythmic and anticoagulant medication. Discussion This case demonstrates for the first time the feasibility of fluoroscopy-free cryoablation using only TOE for guidance.

Where can I find out more

Abstract: What is in store for the guppy? Variation is essential to understanding the genetics underlying biological processes. The guppy provides a huge amount of natural variation that can be studied genetically. This variation has not been produced by mutagenesis screens, but instead has been shaped by natural selection. Thus, combined with emerging genomic resources, the guppy is an ideal organism for understanding the evolutionary genetics and molecular basis of adaptation.
