Trichomonas vaginalis was first described by Donne (1836), who observed the organism in purulent secretions in both women and men, and stated that it was not present in normal vaginal secretions. T. vaginalis was successfully cultured in vitro by Lynch (1915), and there have since been a number of publications containing descriptions of the morphological, epidemiological, and pathological aspec...

OBJECTIVES 1. To assess the effectiveness of laparoscopic Burch and overlapping sphincteroplasty in treating urinary and fecal incontinence. 2. To determine the importance of unilateral pudendal neuropathy in fecal incontinence. METHOD Forty-six women with proven genuine stress incontinence and anal sphincter tears were treated with a laparoscopic Burch colposuspension. Patients with detrusor...

Loss of surgical instrumentation in endoscopic procedures poses problems not faced in traditional surgery. We describe the breakage and subsequent recovery of a 2-mm segment of needle from an Autosuture Endostitch device (U.S. Surgical) during a laparoscopic Burch urethropexy.

We have used a factor analysis of the Stiles-Burch [Opt. Acta 6, 1 (1959)] 10 degrees field color matches to examine the basis of individual differences in the color matches made by observers with normal color vision. The differences in the matches are primarily due to interobserver variations in the macular-pigment density [with a standard deviation (sigma) of 0.12 at 460 nm]; the lens-pigment...

We make explicit the exponential bound on degrees of polynomials appearing in Effective Quillen-Suslin Theorem, and apply it jointly with Hilbert-Burch Theorem to show that syzygy module a sequence m n variables defining complete intersection ideal grade two is free, basis can be computed bounded degrees. In known cases, these bounds improve previous results.

A review of the microgastropod genus Systenostoma is provided. Thai and Malaysian species are transferred to a new genus, Angustopila (type species: Systenostoma tamlod Panha & Burch, 1999). A new subterranean Angustopila species is described here. Conchologically, the new species is most similar to the cave-dwelling, Thai A. tamlod (Panha & Burch, 1999). One Thai species (Systenostoma edentata...

IX .1877, Ehrlich 1 described peculiar types of granular connective tissue cells which he later termed "mast cells." The distinctive characteristic of these cells was the metachromatic staining properties* of their granules. Since then a voluminous literature has appeared regarding the nature of these interesting cells. In the last few years, it has been shown by Adams-Ray and Nordenstam,' Rhod...

Modifications in recorder standardization are required to correct inherent scalar differences among potential differences measured in a given electrocardiographic reference frame. In the frontal plane, agreement between the resultant vectors calculated from unipolar limb lead measurements and from standard lead measurements can be obtained by standardizing the galvanometer for recording the uni...
