Thrombolysis in high risk patients.

The advent of intra-arterially administered thrombolytic agents of minimal antigenicity, together with small gauge good torque control catheters, enables thrombolysis to be used in patients that may previously have been deemed unsuitable for thrombolytic therapy. Thrombolysis may be used even in the presence of factors formerly and empirically considered to be contra-indications. The continued use of thrombolytic agent may also be warranted despite iatrogenic complications such as vessel wall perforation, particularly if the alternative is major amputation. We report on a series of eight patients in whom intra-arterial tissue plasminogen activator was used despite either recent vascular surgery, or iatrogenic vessel perforation. Suggestions for the use of thrombolysis in high risk patients and following iatrogenic complications are discussed.

The management of acute laryngo-tracheo-bronchitis (croup): a consensus view.

The management of croup relies upon the traditional clinical skills of observation and examination. Parental involvement is essential and the appropriate reassurance of the patient is important. Endotracheal intubation is required only in a small percentage of children whose airway is compromised to such a degree as to produce fatigue and/or near occlusion.

Effect of BiTek agar on lysostaphin susceptibility of staphylococci.

Staphylococci which were considered to be lysostaphin susceptible on P agar containing Bacto-Agar showed different degrees of resistance to lysostaphin when tested on P agar made with BiTek agar. As a result, lysostaphin-susceptible strains were misidentified as lysostaphin-resistant strains.

A nonenzymatic preparation of epithelial basolateral membrane for patch clamp.

A preparation has been developed that permits patch clamping of the basolateral membrane of Necturus gallbladder epithelial cells with a high success rate. The epithelium is separated from the underlying tissues mechanically, without enzymatic treatment. Its apical surface is attached to a plastic cover slip, and the basolateral surface, facing up, is cleaned with a suction pipette under microscopic observation. With this cleaning procedure, the success rate in obtaining gigaohm seals increases from less than 1% to approximately 10% of the attempts. The cells appear to retain their structural and functional integrity, as evidenced by electron-microscopic appearance and magnitude of cell membrane voltages. Major advantages of the preparation are that the basolateral membrane domain is preserved and that enzymatic treatment, which could potentially alter membrane proteins, is not necessary.
