[Early changes in magnetic resonance tomography in adrenoleukomyeloneuropathy].

In this case report we describe the MRI findings of a 24-year-old male with adrenoleukomyeloneuropathy, an intermediate form of X-linked adrenoleukodystrophy and adrenomyeloneuropathy. At the onset of illness MRI revealed circumscribed lesions of tracts and fiber systems of the CNS. One year later MRI showed progressive demyelination of the parietal and occipital medullary layer corresponding to the clinical deterioration. Such a progression of MRI findings has not previously been reported in the literature.

Estimation of extracellular space and blood volume using bioelectrical impedance measurements.

The bromide-82 dilution space (extracellular space, ECS) and blood volume (BV) were measured in 21 patients with esophageal and gastric cancer and in 27 patients 18-96 months after total gastrectomy. Resistance (R) and reactance (Xc) from bioelectrical impedance measurements were used to obtain multiple regression equations for ECS and BV. The variables weight, gender, and height 2/Xc were independent predictors of ECS (r = 0.767; P less than 0.0001). Height 2/R and gender were predictors of blood volume (r = 0.856; P less than 0.0001). The mean difference between the Br space and the ECS predicted from impedance measurements was 0 +/- 1.54 (mean +/- SD). The limits of agreement (+/- 2 SD) were therefore +/- 3.08 l or 19.6% of the mean Br space of 15.7 l. The limits of agreement for BV were +/- 789 ml or +/- 19.7% of the average BV of 4008 ml. It is concluded that bioelectrical impedance plethysmography using a single frequency can be used for the estimation of ECS and BV. The wide limits of agreement, however, may limit its used in clinical practice.

Extracellular space, blood volume, and the early dumping syndrome after total gastrectomy.

Extracellular space and blood volume were measured using 82Br dilution and 51Cr-tagged erythrocytes in 24 tumor-free patients after total gastrectomy. Eleven of the patients suffered from early dumping. Age, blood volume, and extracellular space were significantly smaller in dumpers (P less than 0.05). The dumping score could be predicted by a multiple regression model considering blood volume per lean body mass and extracellular space (r = 0.637; P = 0.0039). Rapid (t1/2 less than 360 seconds) emptying of the gastric substitute, assessed using a 99Tc-labeled solid test meal, was significantly associated with dumping in addition to extracellular space and blood volume (r = 0.876; P = 0.0018). Both rapid emptying and a narrow extracellular space seem to contribute to the early dumping syndrome.

Determination of circulating blood volume by measurement of indocyanine green dye in hemolysate: a preliminary study.

In 8 emergency care patients blood volume was determined using Cr5I labelled erythrocytes and indocyanine green (ICG). Prior to measurement of ICG in blood with a spectrophotometer, the blood was hemolyzed with Triton-X. A close correlation of r = 0.97 between the Cr51 and the ICGTR-X estimates was found; the ICGTR-X volume was about 3% lower than the Cr51 volume. In five additional in vitro experiments the ICGTR-X method was found to reflect real volumes with an insignificant error of less than 1%. Blood volume determination with ICGTR-X cannot be applied in cases of circulatory failure. ICG should be administered in a dose of 0.5 mg/kg of body weight. For calibration purposes, a two point calibration curve (point 1: point of intersection of x and y axis; point 2: 5 mg ICG/1 of blood) is sufficient. From these preliminary experiments it is concluded that the ICGTR-X method is a rapid and simple technique of blood volume determination with multiple reproducibility which can be carried out in any clinical laboratory.

[HLA and thyroid cancer].

HLA typing was performed in 51 patients to analyse the pathogenetic background of differentiated and medullary thyroid carcinomas. A higher incidence of Bw62 and DR5 was observed in patients with papillary carcinoma (n = 24), DRw6 antigen in follicular carcinoma (n = 13), and DR3 antigen in patients with medullary carcinoma (n = 11). The DR3 antigen was present in one of two patients with a familial history of medullary thyroid carcinoma. Therefore, HLA typing is not suitable as a screening method for the detection of early thyroid carcinoma.
