Charge fluctuations on membrane surfaces in water

We generalize the predictions for attractions between overall neutral surfaces induced by charge fluctuations or correlations to nonuniform systems that include dielectric discontinuities, as is the case for mixed charged lipid membranes in an aqueous solution. We show that the induced interactions depend in a nontrivial way on the dielectric constants of membrane and water and show different scaling with distance depending on these properties. The generality of the calculations also allows us to predict under which dielectric conditions the interaction will change sign and become repulsive.

[Value of proximate musculocutaneous flaps for covering open wounds caused by decubitus ulcers].

Musculo cutaneous flaps help to cover the important tissues defects of the pressure sore. During 1988, two of our patients in general bad conditions, needed a quick simple treatment for bed sores involving joints. The patients, one who was paraplegic, the other tetraplegic, were suffering from joint lesions in the elbow and both knees. We carried out a musculo cutaneous flap of the brachio radialis and two of the gastrocnemius medialis, once septic conditions had improved. The simple procedure by transfer assured the cover of the skin defect. The results of the treatment being successful allow us to suggest this type of treatment being used in general traumatologic lesions affecting the elbow and knee joints.

Fractures of the frontal sinus.

Fractures of the frontal sinus are frequently seen in patients with cranio-facial injuries. Trauma to the posterior wall and more deeply located tissues: anterior fossa, dura and brain, give an indication of the seriousness of such injuries. We point out some particular aspects of our experience; in the neurosurgical approach to such lesions; we use a classification based on treatment: -when the posterior wall of the sinus is not, or only slightly damaged, we drain it using a thin suction catheter pulled through the fronto-nasal duct, kept in place for six to ten days. -when a comminuted fracture of the frontal arch occurs in the sinus area, a large cortico-cancellous onlay bone graft is used to rebuild a harmonious frontal contour and avoid the risk of secondary deformity.
