Double lateral osteotomy in rhinoplasty.

Double lateral osteotomy has proved to be useful in the management of broad, thick, and heavy maxillary processes. The technique of performing two lateral ostotomies and the indications for its application are described. The results obtained from cadaver dissection and clinical experience with this technique are discussed.

An NADP-dependent Glutamate Dehydrogenase in Chloroplasts from the Marine Green Alga Caulerpa simpliciuscula.

NADP-dependent glutamate dehydrogenase was partially purified from extracts of the marine siphonous green alga Caulerpa simpliciuscula. The enzyme had an apparent Km NH(4) (+) of 0.4 to 0.7 mm and was highly specific for NADPH, alpha-ketoglutarate, and ammonium ions.The bulk of the NADP-glutamate dehydrogenase was isolated with the chloroplast fraction in cell-free preparations of this alga and was released from these "chloroplast fractions" as a soluble enzyme on gentle lysis of chloroplast membranes.

Correlation between the size of the compound muscle and sensory nerve action potentials recorded from the foot in distal axonopathy.

Nerve conduction study was performed on 71 diabetic patients with distal sensorimotor axonopathy. Of 76 lower limbs studied, 46.1% showed no recordable sural compound sensory nerve action potential (CSNAP), and 55.3% no superficial peroneal CSNAP. Only 2.6% revealed no recordable compound muscle action potential (CMAP) from the abductor hallucis (AH) muscle, and 9.2% showed no obtainable CMAP from the extensor digitorum brevis (EDB) muscle. There were fairly good positive correlations between the amplitudes of the sural CSNAPs and AH CMAPs (r = 0.66), and between the superficial peroneal CSNAP and EDB CMAP amplitudes (r = 0.63). There were no instances in which a CSNAP could be obtained from the sural or superficial peroneal sensory nerve, but a CMAP could not be recorded from the AH or EDB muscle. If the CMAP amplitudes of the AH and EDB muscles were reduced to less than 0.3 mV, usually a CSNAP could longer be recorded from the sural and superficial peroneal sensory nerves. The size of the CSNAP is a more sensitive measure compared to the CMAP in revealing the presence of distal sensorimotor axonopathy.

Alabama laws on drug testing in the work place.

Alabama law related to employee work place drug testing consists of the newly enacted drug free work place program, the workers' compensation law and the unemployment compensation law. These laws contain specific requirements relating to the performance of employee drug testing. Physicians will play a key role in the management, supervision and implementation of employer drug testing programs and should become familiar with state and federal laws and regulations pertaining to the operation of those programs.
