Kawasaki disease,or mucocutaneous lymph node syndrome: report of seven cases in North America.

The clinical and laboratory findings in seven children with Kawasaki disease are reviewed. Four of the patients had the more complicated course that has characterized the cases diagnosed in North America. This suggests that the benign forms are often mistaken for other febrile illnesses. The patients were two girls and five boys ranging in age from 4 months to 7 years; six were Caucasian and one was a North American Indian. Fever, redness of the oral mucosa, an erythematous or scarlatiniform rash and cervical adenopathy were seen in all; six patients had the characteristic fingertip desquamation and nonexudative conjunctivitis. Cardiac involvement occurred in four patients, two of whom had coronary artery aneurysm or thrombosis. Arthritis or arthralgia was seen in six patients, and aseptic meningitis occurred in four. Of the three patients with jaundice two underwent laparotomy and excision of a hydropic gallbladder; one of them died from Klebsiella pneumoniae sepsis and disseminated intravascular coagulopathy.     

Sequence of the sites phosphorylated by protein kinase C in the smooth muscle myosin light chain

We have determined the sequence of the sites phosphorylated by protein kinase C in the turkey gizzard smooth muscle myosin light chain. In contrast to previous work (Nishikawa, M., Hidaka, H., and Adelstein, R. S. (1983) J. Biol. Chem. 258, 14069-14072), two-dimensional tryptic peptide maps of both heavy meromyosin and the isolated myosin light chain showed two major phosphopeptides, one containing phosphoserine and the other phosphothreonine. We have purified the succinylated tryptic phosphopeptides using reverse phase and DEAE high pressure liquid chromatography. The serine-containing peptide, residues 1-4 (Ac-SSKR), is the NH2-terminal peptide. The phosphorylated serine residue may be either serine 1 or serine 2. The threonine-containing peptide, residues 5-16, yielded the sequence AKAKTTKKRPQR. Analysis of the yields and radioactivity of the products from automated Edman degradation showed that threonine 9 is the phosphorylation site.     

Anti-anabolic effects of adenosine 3′:5′-cyclic monophosphate. Inhibition of protein synthesis

1. Evidence is presented that cyclic AMP inhibits the incorporation of l-[4,5-(3)H]leucine into protein in a cell-free system from rat liver. This inhibition occurs after aminoacyl-tRNA formation. 2. Microsomal fractions, isolated after the incubation of postmitochondrial supernatant with cyclic AMP and ATP, show a diminished ability to synthesize protein. Both cyclic AMP and ATP are required for this effect. 3. A possible physiological role for the anti-anabolic action of cyclic AMP is discussed in terms of the control of gluconeogenesis.     

A Statistical Review of Malignant Testicular Tumours Based on the Experience of the Ontario Cancer Foundation Clinics, 1938-1961

For the 827 patients with malignant testicular tumours registered at the Ontario Cancer Foundation''s regional clinics in the period 1938-1961, the probability of surviving for five years after treatment was 59.8%; for the 731 patients who received all or part of their initial treatment at the clinics or were not treated anywhere, five-year survival probability was 62.7%. Most deaths from testicular cancer took place in the first two years after treatment, and 90% of recorded recurrences were diagnosed before the third anniversary. Survival rates were strongly influenced by histological type and extent of disease, and to some degree by age. Survival did not seem to be closely correlated with delay after first symptom, site or size of primary lesion, ectopia, surgical treatment of the abdominal nodes, site or dosage of radiation, or chemotherapy. The survival rates in this series of cases compare favourably with those of other large series.     

Three Years' Experience with Implanted Pacemakers

At the University Hospital, Saskatoon, over the last three years, pacemakers have been inserted in 40 patients with complete or incomplete heart block. Fourteen of the patients were females and 26 were males. The average age was 65 years; 12 were over 80 years of age, and the youngest patient was 8 years of age. In none was the heart block due to operation. Thirty-three patients are still alive and well. There have been seven deaths three early and four late. One patient died because of a “runaway” pacemaker, and two as a result of infection persisting around the pacemaker. Twenty-nine Medtronic pacemakers were used and 14 Atricor pacemakers; currently we favour the latter instrument.
