Lumbar spinal manipulation on trial. Part I--clinical assessment.

Thirty-two patients with chronic low back pain were treated three times at weekly intervals with rotational manipulation. Patients with femoral or sciatic root pain were included provided they did not exhibit root compression signs. Background therapy of codeine phosphate was administered throughout. There was a significant increase in spinal flexion measured clinically during the three-week period of manipulation followed by a significant decrease in the three-week period after manipulation. The first week of manipulative treatment was more painful than the corresponding week in the control group but in the second and third weeks there was less pain in the manipulated group. Pain scores were reduced to a significant degree within four weeks of starting treatment only in the group manipulated in the first treatment period. Patients benefitting subjectively from manipulation were more likely to be older and to have had symptoms for a shorter period than those not deriving benefit. The age of onset of symptoms was significantly later in the responders.

Lumbar spinal manipulation on trial. Part II--radiological assessment.

In a trial of manipulation for chronic low back pain, radiographs of the lumbar spine and radiographic assessment of spinal motion were of no value in predicting or assessing the response of the patients to manipulation. Although radiography of the lumbar spine is a commonly requested investigation, it contributes little to the management of such patients except to exclude serious spinal pathology before any form of physical treatment is commenced.

The radiographic demonstration of the dynamic transfer of radio-opaque material from the differential vein to the prostate in the dog.

Radio-opaque contrast medium was injected into the deferential vein of the dog in vivo and was seen to pass, in two of five animals, into the intrinsic veins of the prostate and the cavernous tissue of the prostatic urethra. In other cases an increase in abdominal venous pressure was required to bring about the retrograde flow. The observations support the previously cited evidence that the prostate receives hormonal stimuli via the deferential vein.

Thrombogenicity of arterial catheters and guidewires.

Thrombus formation on the surface of a variety of arterial catheters and guidewires has been studies in dogs. Heparin-bonding of catheters and guidewires greatly reduced surface thrombus deposition even in the most thrombogenic material tested, and under the conditions of these experiements heparin-bonding was more effective than systemic heparinization.

Observations on the behaviour of barium sulphate suspensions in gastric secretion.

A number of barium sulphate suspensions showed varying patterns of stability when provoked with gastric secretion. The stability of the suspensions was affected by the pH, the mucin content and the volume of secretion used. These studies indicate that flocculation of the suspension in the presence of gastric residue decreases as the amount of undiluted barium sulphate in the mixture is increased.

In vivo and in vitro assessment of barium sulphate suspensions.

In vitro methods of testing the efficiency of barium sulphate suspensions in delineating mucosal detail using canine cadaveric stomachs have been described in the literature. In this study a comparison is made between in vitro and in vivo tests in the stomach and small intestine of dogs, using several brands of barium sulphate. The results indicate that there is considerable variation in the behavior of these suspensions between the in vitro and in vivo tests particularly in the stomach. It is our view that in vitro tests of this sort are of little value for assessing the relative advantages and disadvantages of these suspensions in demonstrating mucosal detail.
