Management of a complex diving accident.

After the accidental ascent of a diving bell from 80 m, one diver died from pulmonary barotrauma and the other-though grossly ill-survived. After recompression therapy, this diver was tetraplegic with evidence of patchy microcirculatory damage of brain, cord, liver, kidneys, and gut. All systems eventually returned to normal, except the spinal cord, mainly because of the post-recompression phase of management, in which pharmacological doses of steroids, hyperbaric oxygen, and dextran were used. Although function returned in the upper limbs, the diver remained paraplegic.

[Echocardiographic serial study on movements of the interventricular septum after aorto-coronary bypass].

The data presented show that echocardiographically detected abnormal septal movement is frequent early after coronary bypass surgery but that these abnormalities decrease in many patients during late follow-up. Increased anterior movement of the whole heart during systole and decreased regional myocardial contraction both contribute to the septum abnormalities. However, the overall left ventricular function remains unchanged after coronary bypass surgery.

Quantitative assessment of the quality of medical care provided in five family practices before and after attachment of a family practice nurse.

The standards of patient care were maintained in five urban medical practices after the introduction of family practice nurses. Evaluations were achieved before and after their appointment by the indicator condition method. Minimal explicit criteria for the management of patients with 12 indicator conditions and by the use of 14 drugs were approved by an ad hoc peer group of community physicians. These cirteria were applied to the five practices by the use of a single-blind design and the abstraction of unaltered medical records. A standardized score for each practic e permitted comparison of scores for the management of indicator conditions and for the clinical use of drugs before and after attachment of the family practice nurses. For each of the indicator conditions and the drugs assessed in the five practices similar levels of adequacy were observed in the two study periods. These explicit (objective) audit resutls agreed with the implicit (subjective) assessments of the family practice nurses by their physician colleagues.

Cordycepin. An inhibitor of newly synthesized globin messenger RNA.

The effect of cordycepin (3'-deoxyadenosine) on newly synthesized globin mRNA in cultured mouse fetal liver erythroid cells is investigated. At cordycepin concentrations that do not inhibit amino acid incorporation into acid-precipitable material, the quantity of pulse-labeled (radioactive) globin mRNA nucleotide sequences is reduced by 90%, as compared to adenosine-treated controls. The reduction of radioactivity in globin-specific RNA sequences is greater than the inhibition of total RNA synthesis in experiments in which the labeling times range from 6 to 60 min. Control experiments demonstrate that cordycepin does not reduce the recovery of total cell RNA or steady state (unlabeled) globin mRNA. The hybridization assay used to detect radioactive globin mRNA sequences is independent of the cellular location or the number of 3'-terminal adenylate residues in the mRNA-containing molecules. These data thus indicate that cordycepin inhibits newly synthesized mRNA as effectively as it inhibits ribosomal and transfer RNA synthesis.
