Diastolic time – frequency relation in the stress echo lab: filling timing and flow at different heart rates

A cutaneous force-frequency relation recording system based on first heart sound amplitude vibrations has been recently validated. Second heart sound can be simultaneously recorded in order to quantify both systole and diastole duration

Aesthetic considerations in the cervicofacial management of madelung syndrome

The most common concern in patients with Madelung syndrome who are seeking cosmetic improvement is the deposition of fat in the cervicofacial region. Surgical experience in a series of 15 patients was summarised to provide guidelines for a rational approach to a better aesthetic outcome. The records and clinical photographs of these patients were reviewed. Outcome was assessed in terms of adequacy of debulking, final overall symmetry, smoothness of contour, prominence of scar, and necessity for multiple sessions. Open excision was the preferred primary treatment. A long mid-neck, transverse skin crease incision provided good exposure and was superior to multiple local incisions. Other surgical details worth noting include subplatysmal dissection, thick skin flaps, dissection around instead of into lipomas, appropriate removal of redundant skin, adequate reduction of tumour size instead of total excision, haemostasis, suction drainage, and layered skin closure. Liposuction was a useful adjunct for contouring the sides of the jaws in selected patients

Molecules that make axons grow.

The study of neurite growth in tissue culture has been a productive way to identify substances that may control the behavior of axons in vivo. Molecules that promote the outgrowth of neurites include nerve growth factor, laminin, fibronectin, and a protease inhibitor derived from glia. Evidence that these molecules may influence axon growth and guidance in vivo is discussed. The effects these molecules have at the cellular level are compared, in an attempt to identify common mechanisms of action. Several less well-characterized molecules that influence the behavior of neurites are also discussed
