  • routine transition zone and seminal vesicle Biopsies in all patients undergoing transrectal ultrasound guided prostate Biopsies are not indicated
    The Journal of Urology, 1997
    Co-Authors: Martha K Terris, Tien Q Pham, Muta M Issa, John N Kabalin
    Abstract:

    ABSTRACTPurpose: Transrectal ultrasound guided Biopsies of the transition zone and seminal vesicles have been useful in select patients. More widespread use of these additional Biopsies has been proposed. The efficacy of routine transition zone and seminal vesicle Biopsies was examined.Materials and Methods: From January 1988 to October 1994, 736 transrectal ultrasound guided systematic sextant Biopsies were performed. From October 1994 to July 1995, 161 consecutive patients underwent transrectal ultrasound with systematic sextant, transition zone and seminal vesicle Biopsies.Results: Of the 736 patients undergoing only sextant Biopsies 309 (42.0%) had cancer and 24 (3.3%) required repeat biopsy, compared to 55 (34.2%) and 4 (2.5%) of 161 undergoing combined sextant, transition zone and seminal vesicle Biopsies. Prostate cancer was found only in the systematic sextant Biopsies in 43 of the former 55 patients (78.2%), and in the transition zone and systematic sextant Biopsies in 11 (20.0%). One patient (1....

  • original articles prostate cancer indications for ultrasound guided transition zone Biopsies in the detection of prostate cancer
    The Journal of Urology, 1995
    Co-Authors: Martha K Terris, John E Mcneal, Thomas A Stamey
    Abstract:

    ABSTRACTTransrectal prostate ultrasound and systematic sextant Biopsies have improved peripheral zone cancer diagnosis but they may miss many cancers arising in the transition zone. Biopsies directed into the transition zone have been used to detect residual prostate cancer in patients diagnosed by transurethral resection and they have been suggested as potentially useful additions to systematic sextant Biopsies. To define the indications for transition zone Biopsies 187 men underwent evaluation including systematic sextant Biopsies and transition zone Biopsies. These patients were classified into 4 categories based on clinical presentation. Category 1 included 26 men with palpable nodularity and an elevated prostate specific antigen (PSA), of whom 16 (61.5%) had positive Biopsies but none was positive only in the transition zone Biopsies. Category 2 consisted of 49 men with sonographic abnormalities in the transition zone, of whom 15 (30.6%) had positive Biopsies, including 2 (13.3%) with only positive t...

  • Pseudo-buried Barrett’s post radiofrequency ablation for Barrett’s esophagus, with or without prior endoscopic resection
    Endoscopy, 2013
    Co-Authors: Roos E. Pouw, Mike Visser, Robert D. Odze, Carine Sondermeijer, Fiebo J.w. Ten Kate, Bas L. Weusten, Jacques J. Bergman
    Abstract:

    Background and study aim: In our experience, Biopsies from small residual islands of nonburied Barrett’s mucosa after radiofrequency ablation (RFA) are occasionally reported by pathologists to contain “buried Barrett’s” upon histological evaluation, despite the fact that these islands of columnar mucosa were visible endoscopically. The aim of this study was to evaluate the frequency of buried Barrett’s in Biopsies obtained from small residual Barrett’s islands (  Patients and methods: Biopsies obtained from normal-appearing neosquamous epithelium and from small Barrett’s islands (  Results: A total of 2515 Biopsies were obtained from neosquamous epithelium during follow-up post-RFA. Buried glands were found in 0.1 % of Biopsies from endoscopically normal neosquamous epithelium. However, when small islands of columnar mucosa were biopsied, buried glands were detected in 21 % of Biopsies. Conclusion: To avoid accidental sampling of small islands resulting in a false-positive histological diagnosis of buried Barrett’s, thorough inspection should be performed before obtaining Biopsies during post-RFA follow-up.

  • one pass co2 versus multiple pass er yag laser resurfacing in the treatment of rhytides a comparison side by side study of pulsed co2 and er yag lasers
    Dermatologic Surgery, 2001
    Co-Authors: Victor E Ross, Charles H Miller, Ken J Meehan, Joe Mckinlay, Paul Sajben, John P Trafeli, David J Barnette
    Abstract:

    Background. The CO2 laser is normally described as an aggressive resurfacing tool, whereas the erbium:YAG laser has enjoyed a reputation as the ideal tool for superficial resurfacing. The implication from many studies is that the CO2 laser is incapable of “minimally invasive” resurfacing. Objective. To compare a short-pulsed CO2 laser with an Er:YAG laser over a range of parameters intended to produce equivalent microscopic and clinical injuries. Methods. A prospective, randomized, comparative interventional trial was conducted in a tertiary care teaching hospital. Thirteen patients with facial wrinkles were enrolled in the study. A side-by-side comparison was performed using periorbital and perioral regions as treatment sites. One side was treated with a pulsed CO2 laser and the other with an Er:YAG laser. Postauricular skin was treated in an identical fashion to the study sites and biopsied for microscopic analysis. The Biopsies were obtained before treatment, immediately after treatment, and either 3 or 6 months after treatment to evaluate the acute level of injury and subsequent degree of fibroplasia. Photographs were taken at baseline, immediately after treatment, 1, 2, and 6 weeks, and 3 and 6 months after treatment. Nine physicians evaluated the photographs for erythema, pigmentation, and wrinkle improvement. Results. Investigator assessment showed no statistically significant differences between the lasers with respect to hyperpigmentation and wrinkle reduction. There was less erythema at the CO2 laser-treated sites 2 weeks after treatment; the differences had resolved by 6 weeks after treatment. Histologic examination demonstrated equivalent dermal thermal injury on immediate postoperative Biopsies and equivalent fibroplasia on subsequent Biopsies. Both CO2 and Er:YAG laser-treated sites showed overall modest wrinkle improvement compared to the pretreatment photographs. Conclusion. When CO2 and Er:YAG lasers are used in a manner such that there are equivalent immediate postoperative histologic results, equivalent healing and cosmetic improvement occurs. One can use CO2 laser with one pass to mimic a moderately aggressive Er:YAG laser treatment.
