PURPOSE Humans can reduce inorganic nitrate (NO(3)(-)) to nitrite (NO(2)(-)), nitric oxide (NO), and other bioactive nitrogen oxides. The purpose of this study was to test the hypothesis that a single dose of inorganic nitrate before exercise might enhance the tolerance of endurance athletes to high intensity exercise. METHODS Eleven cyclists (age = 34.3(More)
OBJECTIVE The aim was to determine the feasibility of surgical identification and pathological ultrastaging of sentinel nodes (SNs) in vulvar carcinoma and to evaluate whether SN negativity rules out the possibility of metastasis in other nodes and can therefore avoid conventional lymphadenectomy. MATERIAL AND METHODS In 26 patients with vulvar squamous(More)
BACKGROUND Sarcomatous neoplasms of the uterine corpus are still a challenge in terms of obtaining prognostic factors and the most optimum complementary treatment to surgery. The most important prognostic factor is stage; relapses usually appear during the first 2 years, and most patients die within the first 3 years. We have performed a multivariate study(More)
BACKGROUND Primary carcinomas of the fallopian tube are rare and their preoperative diagnosis is difficult due to the lack of specific symptoms. CASES We present two tumors diagnosed in women 74 and 77 years old. On examination both patients presented as acute pelvic peritonitis with abdominal pain and tenderness with guarding and rebound, as well as(More)
BACKGROUND To assess the potential role of magnetic resonance imaging (MRI) in evaluating the response of cervical tumor to neoadjuvant chemotherapy. METHODS We studied 14 patients with locally advanced carcinoma of the cervix. MRI was performed before and after each cycle. All patients underwent laparotomy four weeks after the last cycle. MR images after(More)
The aim of this study was to determine the effects on plasma lipids and lipoproteins of oophorectomy and various hormone replacement therapy (HRT) delivery systems using low doses of medroxyprogesterone acetate (MPA, 2.5 mg/day). A total of 90 women completed the 1-year follow-up period. Patients were randomly assigned to five groups. The first (n = 16)(More)
The maternal and perinatal outcome of seven gravidas receiving 2.2-2.5 mg/kg per day of indomethacin for polyhydramnios are reported. Such therapy was started between 26 and 33 weeks of gestational age (mean, 30.4 weeks) and lasted for 20.1 days (range, 2-37 days). Median of amniotic fluid index ranged from 47 at the start of therapy (range, 32-53) to 15(More)
Our objective was to assess the applicability of hysterectomy by the vaginal route completely performed with Autosuture staples. Between January 1992 and September 1993, 5 vaginal hysterectomies using Autosuture staplers were performed by the authors. Five vaginal hysterectomies matched for age, parity, and uterine size performed by the same surgeons(More)
We present a technique that allows postoperative adjustment of the sling tension in female patients with urinary stress incontinence (USI). Twenty-one female patients with urodynamically proven USI were prospectively evaluated. Subjective and objective evaluation was made preoperatively, 6 months postoperatively and yearly thereafter. Mean age was 63.5;(More)
This report describes an intraabdominal small cell tumor in a 37-year-old woman, with clinical, topographic, and morphologic features highly suggestive of the desmoplastic small round cell tumor. Immunohistochemical analysis revealed a polyphenotypic profile consistent with this tumor--positivity for keratin, epithelial membrane antigen, neuron-specific(More)
