A comparison of fluorescent and nonfluorescent light sources for phototherapy.

We have compared fluorescent and nonfluorescent light sources for phototherapy for newborn infants with hyperbilirubinemia. Phototherapy was provided by a tungsten halogen lamp and conventional fluorescent light with identical radiant flux of 6 microW/sq cm. For 22 infants treated with the nonfluorescent lamp the mean duration of phototherapy was 33.77 hours and the mean reduction of bilirubin was 3.84 mg/100 ml/day. This did not differ significantly from infants treated with conventional fluorescent lights. The nonfluorescent light can be utilized for infants in incubators or on radiant warmers. These results provide additional support for the relationship between radiant flux as a practical measure of phototherapy dose and the clinical response of a reduction in serum bilirubin.

[Total hip prosthesis. Current indications (author's transl)].

The various problems posed by total hip prosthesis are first described. The authors then analyse the various parameters which should guide the choice of this technique which must be used only when all other solution have failed. The recent development of prostheses without cement has made it possible to widen the application of this surgery to younger patients. Two special cases are finally reported: the role of total prostheses in the treatment of sequelae of fractures of the acetabulum, and in disarthrodesis of the hip with insertion of a total prosthesis.

Hyperkalemia with cardiac arrhythmia. Induction by salt substitutes, spironolactone, and azotemia.

In two patients, severe hyperkalemia and serious cardiac arrhythmia developed after excessive use of potassium-containing salt substitutes. Both had impaired ability to handle and excrete additional potassium load due to chronic congestive heart failure, azotemia, and administration of spironolactone. Prompt recognition of the arrhythmia and immediate restoration of the cardiac rate and rhythm by pacemaker support followed by intensive regimen to lower the serum potassium prevented a potentially fatal outcome. These cases emphasize the potential danger of salt substitutes when used by patients who are predisposed to retain potassium.

Exchange transfusion in the neonate: a controlled study using frozen-stored erythrocytes resuspended in plasma.

During a nine-month period 43 consecutive infants who needed exchange transfusions for the management of their hyperbilirubinemia randomly received whole blood less than 5 days old (control group) or frozen erythrocytes diluted in plasma (experimental groups). There was no different prior to and after exchange transfusions in total protein, albumin, globulin, immunoglobulins, bilirubin, and hematocrit in the control group versus the experimental group. The efficacies of bilirubin removal, as measured by delta bilirubin, were the same in the two groups. Advantages of exchange transfusion with freeze-preserved erythrocytes suspended in type-specific plasma are discussed.

[Aortic ruptures in traffic accident traumatology].

8 cases of rupture of the aorta seen in a series of 62 autopsies were studied in the context of a multidisciplinary enquiry into road accidents. In the light of these cases, the literature and experimental findings, different mechanisms are described, an essential step in the prevention of this lesion which is the main cause of death in 15 p. cent of cases.

[Circular fractures of the skull base during traffic accidents].

With reference to 5 cases of circular fracture of the base of the skull occurring in relation to road accidents, the literature is reviewed. Two different types may be distinguished: --"compression" fractures, --"hyperextension' fractures, the latter being special on the basis of the site of the fracture line and the application of forces via the face or chin. Reconstruction of trajectories during accidents, on the basis of the anatomical lesions and the damage caused to vehicles, as well as the study of films made during the experimental reproduction of similar lesions, make it possible to explain the mode of production of these hyperextension fractures. Such understanding is essential to the study of safety precautions for vehicle occupants.

[Early detection of venous thromboses of the lower limb in traumatology by labelled fibrinogen].

In emergency traumatology, the iodine 125 labelled fibrinogen test is useful in the early detection of phlebitis in patients in whom the routine use of heparin is not possible--fractures of the cervical spine, severe cranial trauma, elderly subjects. It makes possible the institution of appropriate heparin therapy, without waiting for clinical signs to become evident. We noted that isotopic venous thromboses occured very frequently and very early, and that clinical signs, when present (50 p. cent of cases) occurrer 24 to 48 hours after the appearance of isotopic signs.

Restoration of normal red cell size after treatment in megaloblastic anaemia.

The return of the MCV to normal after treatment in megaloblastic anaemia follows a biphasic pattern. The initial more rapid decline in MCV is due to disappearance of pretreatment macrocytes from the circulation and the rate of fall is determined by their mean cell life. The second slower component is probably due to a mixture of pretreatment macrocytes and new macrocytes, the result of a young red cell population. The MCV often returned to normal most rapidly in the most severely megaloblastic patients due to a very short mean red cell life span. However, there was no significant correlation between either initial MCV or red cell count and the time after treatment for a return of a normal MCV.
