[Side reaction after lumbar myelography with dimer-x (author's transl)]

The existence of several very impressive spinal paroxysms after lumbar myelography with Dimer-X1 caused us to make a retrospective investigation of 327 patients with 355 myelographies. In 7.1% of the investigations we have found partly heavy, but mostly reversible neurological complications. The latter cannot be classified, contrary to prevailing statements, in spinal, meningeal or cerebral reactions, since mostly all 3 anatomical structures are being concerned. Corresponding casuistical information are being presented and with their neurological symptomatic discussed. The spinal paroxysms appeared approximately 6 hours after the myelography and lasted over 8-10 hours, in spite of intensive therapeutical efforts. The pathogenesis points to a multifactorial occurrence caused by the coincidence of an increased dosage of the contrast media, too bed rest time, rising of the contrast media in the spinal cord zone and disturbed liquor fluid circulation and contrast media resorption. Pathophysiologically is in connection with spinal cramps an epileptic mechanism probable. Additional spinal reflexive components could be an explanation for the little therapeutical effect of Diacepam (Valium), which is contrary to the statement in the literature. We have seen a better effect in particular cases with Phenothiazine. With strict observance of specific precautionary measures, the Dimer-X seems to be a good media for the presentation of the lumbar subarachnoid space. A further development in this field is desirable.

[The involvement of the position of the femoral head through intertrochanteric osteotomies (author's transl)]

The definition of capacity and strain of the hip joint has since Pauwels (1965 and 1973) been examined and quantitative and qualitative described by various authors. In the following it is attempted to state the relations between intertrochanter correction and the position of the hip joint, which enable a declaration on the dislocation of the main carrying zone of the head of femur. Factors and methods being complementary and such having an effect of contrary sence are thereat especially described.

Predicting offender-patients' reconvictions

In 1963–4 the Oxford University Penal Research Unit managed to collect information about 90 per cent of the offender-patients who were admitted to N.H.S. and Special Hospitals under hospital orders made by criminal courts: this cohort has been described in Crime and Insanity, Vol. II, by Walker and McCabe (1973). One of the by-products of the follow-up of these offender-patients was a rough and ready scoring system for predicting reconvictions (within a two-year follow-up) of 456 offender-patients who were allowed to leave hospital within a year of admission. A prediction system can be used to assist human decision-making (though it should not be a substitute for it)∗ and can also be used to assess the efficacy of measures—such as after-care—by seeing whether individuals with equal predicted reconviction-rates do better with than without the measure (Mannheim and Wilkins, 1955).
