When Is Sentinel Node Biopsy Indicated in High-Risk Ductal Carcinoma in situ? Four Hundred Sixty-Eight Cases from Three Institutions.

Introduction: Sentinel lymph node biopsy (SLNB) in ductal carcinoma in situ (DCIS) is not indicated. However, in certain cases (size >3 cm, high grade, mass effect on mammography, or palpable mass), it may be possible to find incidental invasive carcinoma (IC) that requires an SLNB. We studied the correlation of the aforesaid factors with the probability of finding IC in the surgical specimen.

Surgical procedures before and after starting chronic hemodialysis in a predominantly male population with high prevalence of diabetes.

Purpose: The purposes of this study were to analyze changes in the frequency of different categories of surgical procedures after initiation of chronic hemodialysis (HD) and to identify the types of procedures associated with in-hospital postoperative mortality.

Methods: This was a retrospective analysis of surgical procedures performed in an incident HD population of 392 patients followed in the dialysis unit of one hospital over 15 years. Among these patients, 384 were men and 258 had diabetes mellitus.

Hospitalizations before and after initiation of chronic hemodialysis.

Hospitalization rate is high in patients on chronic hemodialysis (HD). We investigated whether initiation of HD changes the rate and length of hospitalization. We analyzed hospitalizations in HD patients in one hospital over 15 years.

Hospital admissions in elderly patients on chronic hemodialysis.

Background: The purpose of this study was to determine whether number of hospital admissions per patient per year (n/[pt-yr]) and hospital days per patient per year (d/[pt-yr]) differ between elderly and younger patients on chronic hemodialysis (HD).

Patients And Methods: In a retrospective cohort analysis of incident HD patients in one dialysis unit over 15 years, we compared 166 HD patients older than 70 years (77.1 ± 4.

Death during hospitalization in patients on chronic hemodialysis.

Mortality from various causes is higher in patients on chronic hemodialysis (HD) than in the general population. There is evidence suggesting that some of the deaths in HD patients are preventable. To identify potentially preventable causes of death, we analyzed deaths that occurred in HD patients during hospitalization over a period of 15 years.

Hypothyroidism and renal function in patients with systolic heart failure.

The extent to which hypothyroidism affects renal function in patients with heart failure remains incompletely explored, despite the known adverse prognostic implications of renal dysfunction in these patients.In a pilot retrospective study, we evaluated 75 patients (age, >or=18 yr) with left ventricular ejection fractions <0.40.

Wall-corner classification using sonar: a new approach based on geometric features.

Ultrasonic signals coming from rotary sonar sensors in a robot gives us several features about the environment. This enables us to locate and classify the objects in the scenario of the robot. Each object and reflector produces a series of peaks in the amplitude of the signal.

Characterization and expression of the transcription factor PU.1 during LPS-induced inflammation in the rainbow trout (Oncorhynchus mykiss).

The transcription factor PU.1 plays a key role in hematopoietic lineage development and therefore in determining immune cell fate. A full length cDNA transcript of 1237 nucleotides encoding a highly conserved putative protein of 293 amino acids was identified by EST analysis in lipopolysaccharide (LPS) activated trout macrophages.
