    Aims:  To assess the clinical, morphological and immunophenotypic characteristics of breast carcinomas showing patterns of mixed epithelial and myoepithelial differentiation.Methods and results:  Included in the study were four carcinomas containing a mixed population of epithelial and myoepithelial cells identified using morphological features at the light microscopic level which were found amongst a review of 500 archival cases and two recently accessioned cases. The carcinomas varied in size from 20 to 38 mm and all were grade 3 ductal carcinomas. Most showed nodular and sheet-like cellular aggregates, although one case showed small solid cell aggregates with duct formation. The cells were large, round, polygonal or spindle-shaped and had areas of clear or eosinophilic cytoplasm in variable proportions. Foci of metaplasic carcinoma were present in three cases. All cases showed strong, patchy positivity for cytokeratin (CK)14, calponin, smooth actin and muscle specific actin. Epithelial membrane antigen and CK8 were positive in a similar proportion of cells. One patient died 23 months following diagnosis with metastatic carcinoma, another patient died of unrelated disease and four patients are alive with follow-up ranging from 18 months to 25 years.Conclusions:  High-grade carcinomas of the breast showing patterns of mixed ductal and myoepithelial differentiation may show additional morphological features such as foci of metaplasia and appear to have a good prognosis similar to myoepithelial cell-rich carcinomas. However, young age and lymph node metastasis may portend a worse prognosis.

    Abstract Tracer (self)-diffusion coefficients of K+ have been measured using the diaphragm cell in seven compositions of the NaCl−KCl−H2O system. These data complete the full set of isothermal vector transport properties for five of these compositions.

    Abstract While the clinical symptomatology and radiographic findings of acute suppurative infection of the epitrochlear lymph nodes of the arm have been previously described [1], ultrasonographic findings have not been reported. This case report demonstrates that sonograpic identification of enlarged epitrochlear lymph nodes immediately confirms the diagnosis. We summarize the clinical, radiological, and sonographic findings of acute suppurative infection of the epitrochlear lymphnodes.

    Notes:
    Abstract A retrospective study of sixty consecutive cases of proven intussusception with attempt at contrast enema reduction was performed to evaluate currently proposed contraindications to such reduction. When patient age, duration of symptoms, presence of small bowel obstruction and presence of a dissection sign were considered alone, none of the findings indicated irreducibility. Our overall reduction rate was 72% with a complication rate of 3%. This is similar to previously reported series and we concur with more recent publications that the only contraindications to non-surgical reduction of intussusception are free intraperitoneal air, peritonitis or evidence of infarcted bowel. Only when we encountered a combination of symptoms being present for greater than 48 hours and the presence of both small bowel obstruction and a dissection sign was reduction likely to be unsuccessful. However, the presence of a prognostic indicator occurring alone should not be considered a contraindication.

    Notes:
    Abstract Ectopic pancreas is the most common congenital anomaly in the gastric antrum. In some patients, there is a distinct tendency for this lesion to produce intermittent crampy abdominal pain byprovoking gastroduodenal prolapse. This condition should be considered after a more distal prolapse from intussusception is excluded. An upper gastrointestinal series performed during an episode of symptoms may be diagnostic of this entity.

    Notes:
    Abstract We reviewed eight cases of gastrointestinal duplication cysts to determine whether the combination of an echogenic inner mucosal layer and hypoechoic outer muscular layer could be seen consistently enough to be of diagnostic value. We compared our findings to those seen in twenty-seven other abdominal cysts and conclude that when identified together, the two layers are highly suggestive, if not completely diagnostic of enteric duplication cysts.

    Notes:
    Abstract Bundles of taenia coli muscle as small as 25 micrometers in diameter were dissected from guinea pigs and incubated in an organ culture media for several days. We found that use of an organ-culture bathing solution greatly extended the in vitro responsiveness as well as survival of such small bundles. Electronmicrographs showed that surviving strands of cells constituted only a very small fraction of the cross section of these bundles. Noneteless, still they supported propagating nondecrementing action potentials. This means that in some cases strands, only a few cells in cross section, supported propagating action potentials. The long length constant and parallel orientation of cells provide a basis assuming cells act as parallel core conductor segments. For these reasons we have called into question the notion that for propagation to occur there must be a facilitating cooperation between large numbers of smooth muscle cells in parallel. Indeed we suggest that the limiting size for propagation is a strand of single cells.

    Abstract Background. Pelvocalyceal dilatation (PCD) is often detected by sonography during the prenatal period. Prenatal detection of PCD should affect the prevalence of PCD in children with urinary tract infection (UTI).¶Purpose. To determine the prevalence of abnormal sonographic findings in a population of children undergoing first imaging evaluations after UTI and to determine if the prevalence has changed from an earlier study at the same institution.¶Materials and methods. The findings on consecutive first renal and bladder sonographic examinations in 844 children (745 girls, 99 boys) with UTI were retrospectively reviewed. Cystograms were performed in 743/844 (494 nuclear, 249 fluoroscopic). Only children with known congenital malformations or other significant disease were excluded.¶Results. Sonography was abnormal in 141/844 (16.7 %). PCD was noted in 27/844 (3.2 %), with mild PCD in 18/844 (2.1 %) and moderate or severe PCD in 9/844 (1.1 %). Hydroureter without PCD was noted in 6/844 (0.7 %). Parenchymal abnormalities were present in 42/844 (5.0 %) and bladder wall thickening in 43/844 (5.1 %). Vesicoureteral reflux was present in 186/743 (25.0 %). When compared to historical controls, PCD and hydroureter were significantly less prevalent than 1 decade earlier (P 〈 0.0001).¶Conclusion. The prevalence of PCD in children under first imaging evaluation for UTI declined significantly during the last decade. These data may be useful in the design of imaging strategies for children with UTI.

    Abstract The degree of relatedness among mammalian xanthine oxidases (XO) was determined by microcomplement fixation. Rabbit anti bovine milk XO serum was tested against xanthine oxidase (homologous protein) and against the heterologous proteins of bovine liver, monkey liver, rat liver, lactating cow serum, nonlactating cow serum, and steer serum. The indices of dissimilarity for the heterologous proteins were expressed as units of immunological distance and the percent sequence differences among these proteins inferred from the y=5x relationship where y is immunological distance and x is percent sequence difference. Rat liver XO differed by approximately 27% in amino acid sequence from bovine milk XO. In order of increasing immunological distance from bovine milk XO, the sources of XO ranked as follows: lactating cow serum 〈 nonlactating cow serum 〈 steer serum = beef liver 〈 monkey liver 〈 rat liver. The monkey ranked much closer than the rat in order of phylogenetic kinship to the cow. Starch gel electrophoresis of liver, milk, and serum showed that the milk and the serum contained only cationic forms of xanthine oxidase while all the liver samples tested contained cationic as well as anionic forms of the enzyme. The electrophoretic mobility properties of xanthine oxidase confirmed the polymorphic nature of the enzyme as revealed by the immunological data.

    Abstract The National Optical Astronomy Observatories (NOAO) are planning to buld two 8 m telescopes, one for Mauna Kea, Hawaii, the other for a site in Chile. Optical configurations, primary mirror systems, and the telescope mounting are discussed. A new optical testing method is outlined. The system imaging goal is 0.25” FWHM. Construction could begin in the early 1990's.
