- In a population based epidemiological survey of juvenile chronic arthritis (JCA), performed in Western Sweden in 1983, an incidence of 12/100,000 was found. The estimated prevalence was 56/100,000. Subgroup distribution showed a preponderance of mono- and pauciarticular forms. The peak age of onset was between 0 and 4 years of age. Girls predominated over boys in a ratio of 3:2. Overall, 30% were antinuclear antibody (ANA) positive, 9% rheumatoid factor (RF) positive, and eye involvement occurred in 10% of the children. The results suggest differences in population based studies of JCA compared with previously reported hospital based series.

Growth rate dispersion in MSMPR crystallizers

- A model is presented which relates the crystal size distribution (CSD) from a mixed-suspension, mixed-product-removal (MSMPR) crystallizer to the distribution of growth rates. This model is based on the assumption that individual contact nuclei have some inherent growth rate which remains constant, but the growth rate may vary from crystal to crystal. The crystal size distribution can be calculated from prior knowledge of the growth rate distribution. A limited knowledge of only the coefficient of variation and the mean growth rate permits an approximation of the expected crystal size distribution. Conversely, estimates of the mean and variance of the growth rate distribution can be determined from the moments of the CSD from an MSMPR crystallizer

A constant-temperature Raman cell for the study of supersaturated aqueous solutions

- In order that the phenomena of crystal nucleation and growth from solution can be fully understood, the current knowledge of supersaturated solution structure must be extended. Previous studies on Raman spectroscopy of aqueous metal nitrate solutions indicated the presence of solvated ions, solvent separated ion pairs, contact ion pairs, and ion agglomerates as a function of concentration. Unfortunately, the concentration range of these studies did not include supersaturated solutions. It is the purpose of this work to describe an experimental technique which allows the study of supersaturated solutions.

Radio-iodobenzylguanidine scintigraphy of neuroblastoma: conflicting results, when compared with standard investigations
- 1989

- Seventy-one patients with neuroblastoma (NB) and 25 patients with other neoplastic or nonneoplastic diseases were studied with MIBG scintigraphy. Sensitivity and specificity at diagnosis were 94% and 88%, respectively. Of 52 patients with NB studied during follow-up, 14 had on one or several occasions conflicting results, when the findings at MIBG scintigraphy were compared to standard investigations (SI: CT scan, bone scan, x-ray, and ultrasound). The correlation of MIBG scintigraphy and SI to clinical outcome were in these 14 patients not significantly different. Adding VMA-excretion measurements did not significantly improve the predictive value of MIBG scintigraphy or SI. Patients with tumor-suspected lesions only at MIBG scintigraphy should be followed closely and the nature of the lesions should be explored through biopsy.
