Intranuclear inclusions in Bence Jones lambda plasma cell myeloma

A patient with plasma cell myeloma producing only Bence Jones lambda protein was found to have pale intranuclear inclusions in the majority of the bone marrow plasma cells. These inclusions, previously undescribed in myeloma patients producing only Bence Jones protein, contained Bence Jones lambda protein, were non-electron dense, bound by a single membrane, and contained no cytoplasmic structures. Intracytoplasmic inclusions were not present, and the perinuclear cistern was not dilated. Thus, the inclusions may represent intranuclear protein synthesis with anomalous release in the abnormal cells.     

Esophageal strictures in children: treatment by serial balloon catheter dilatation

Grüntzig balloon catheters were used to dilate ten esophageal strictures in eight infants and children. Five infants who had anastomotic strictures following esophageal atresia repair gained complete resolution of their strictures, usually after one or two dilatations. Three older children who had strictures following esophageal re-operation or reconstruction required longer courses of dilatations to achieve consistent esophageal patency. The technique failed in two chronic strictures of two and one-half and nine years' duration. Balloon catheter dilatation, begun in the early postoperative period, is a safe, effective method for dilating esophageal strictures.     

Percutaneous angioplasty in clinical management of renovascular hypertension: initial and long-term results

Between January 1980 and July 1983, percutaneous transluminal angioplasty was attempted on 137 stenotic renal arteries in 100 patients. At termination of follow-up studies (3-39 months, mean of 16 months), 70% of those treated for hypertension had benefited from the procedure. Stenosis secondary to fibromuscular dysplasia responded better than stenosis from arteriosclerosis (85% and 65% of the patients, respectively). Benefit was minimal for those with stenosis of the renal artery ostium or renal insufficiency. Determining levels of renal vein renin before angioplasty is helpful in selecting patients; following angioplasty, this has considerable significance in predicting the success of the procedure.     

Interleukin-1α and interleukin-1 receptor antagonist in the urine of children with acute pyelonephritis and relation to renal scarring

Urinary concentrations of interleukin-lα (IL-lα) and interleukin-l receptor antagonist (IL-Ira) standardized to urinary creatinine concentrations were studied. The median standardized IL-1α creatinine quotient in children with first-time acute pyelonephritis was 3.6 pg/μmol, but was non-detectable in children with recurrent pyelonephritis, children with non-renal febrile conditions and children convalescent after acute pyelonephritis ( p < 0.05–0.01). IL-lra levels were also significantly higher in children with acute first-time pyelonephritis (median of 239 pglpmol) compared to these three groups of children ( p < 0.01–0.001). The highest urinary 1L-lra levels, however, were found in the healthy controls (median value 1.019; p < 0.001). Both cytokines were higher among children younger than one year compared to older children. The acute IL-lα creatinine quotients were lowest in children with uptake defects on ^99mTC-dimercaptosuccinic acid (DMSA) scintigraphy both during the acute infection (reflecting the acute inflammation) ( p < 0.001) and 1 year after the acute infection (reflecting permanent kidney scarring) ( p < 0.01). In conclusion, persisting high urinary levels of 1L-lα were associated with less renal inflammation and scarring.
