STUDY OBJECTIVE The aim of this study was to estimate the cumulative incidence of vaginal cuff dehiscence in robotic-assisted total hysterectomies in our patients and to provide recommendations to decrease the incidence of vaginal cuff dehiscence. METHODS This was an observational case series, Canadian Task Force Classification II-3 conducted at an academic and community teaching hospital. A ...

Repair of massive rotator cuff tears is technically difficult but often feasible. Technical and biological challenges to a successful repair include inelastic poor-quality tendon tissue, scarring, muscle atrophy, and fatty infiltration. Fatty infiltration of the involved rotator cuff muscles has been identified as an important negative prognostic factor for the outcome after repair of massive r...

A 53-year-old man with a history of a bilateral lung transplantation (LT) at the age of 39 underwent electrophysiological testing of supraventricular tachycardia (SVT). At baseline, the SVT persisted, and exhibited positive P waves in the inferior leads and lead V1. The activation map in the left atrium (LA) revealed a centrifugal pattern from the right pulmonary vein (RPV) cuff ( F1 Panel A). ...

SUMMARY This paper describes a fault in the cuff of a reinforced latex endotracheal tube, where the cuff splits into layers. On attempting to deflate the cuff, the pilot balloon subsides but not the cuff itself. The cause of this fault is examined, and, by implication, steps to eliminate it during manufacture suggested. It would appear that not all such available latex endotracheal tubes are po...

Rotator cuff tears are a ubiquitous cause of shoulder pain and disability. Full thickness rotator cuff tears are present in 19-21% of the general population, and their prevalence increases with age. The incidence of this problem is exacerbated by the ever advancing age of our patient population. Thankfully, with advances in arthroscopic rotator cuff repair, this has become a treatable problem w...

The subacromial bursa is recognized as a site associated with the shoulder pain caused by rotator cuff disease in the middle-aged and elderly. Substance P is contained in primary afferent nerves, and its quantity increases during chronic pain. The amount of substance P in the subacromial bursa of patients with rotator cuff disease was examined. Radioimmunoassay and immunohistochemistry were emp...

OBJECTIVES Tracheal mucosal perfusion is compromised at an endotracheal tube (ETT) cuff pressure of 30 cm H(2)O, and blood flow is obstructed at a pressure of 50 cm H(2)O. METHODS We measured the change in pressure of air-filled cuffs of 6.0 and 7.5 ETTs and a size 4 laryngeal mask airway (LMA) from sea level to 2400 m. The ETTs and LMA cuff measurements were done with the devices uncontained...

The aim of this study was to examine interleukin-6 production and the activation of signal transducer and activator of transcription-3 (STAT3) in ruptured rotator cuff tendon. Specimens of ruptured rotator cuff tendons were analysed using real-time reverse transcriptase polymerase chain reaction, Western blotting and immunohistochemistry. Specimens of co-existing inflammatory subacromial synovi...

Arthroscopic rotator cuff repair is being performed by an increasing number of orthopaedic surgeons. The principles, techniques, and instrumentation have evolved to the extent that all patterns and sizes of rotator cuff tear, including massive tears, can now be repaired arthroscopically. Achieving a biomechanically stable construct is critical to biologic healing. The ideal repair construct mus...

We have assessed the efficacy of tracheal tube cuff inflation in the oropharynx as an aid to blind nasotracheal intubation in 20 ASA I and II patients undergoing elective oral surgery. The trachea was intubated once using the technique of tracheal tube cuff inflation in the oropharynx and once keeping the tracheal tube cuff deflated throughout the manoeuvre. With the cuff deflated, intubation w...
