The effectiveness of a sequential regimen consisting of mifepristone, 10 mg/day for 15 days, followed by nomegestrol acetate (NOMA), 5 mg/day for the next 13 days, for inhibiting ovulation and maintaining regular bleeding cycles was assessed in 10 surgically sterilized volunteers who were followed for one pretreatment and three treated cycles. Hormonal determinations in blood and urine, ovarian...

Cytomegalovirus (CMV) colitis is the most common infection of the CMV gastrointestinal disease. Patients with CMV colitis soften manifest with fever, abdominal pain, watery diarrhea, bloody stool, massive bleeding and occasionally with mega colon and perforation. Colonic ulcer bleeding can be self-limited, but may recur intermittently. Massive colonic bleeding and perforation can be life-threat...

Irregular bleeding remains a common reason for the discontinuation of progestin-only contraception. The levonorgestrel releasing intrauterine system (LNG-IUS) has profound morphological effects upon the endometrium. Specific features are gland atrophy and extensive decidual transformation of the stroma. Morphological changes in the endometrium may be associated with perturbation of mechanisms r...

Endoscopic analysis with virtual chromoendoscopy, including narrow-band imaging (NBI), allows the prediction of histology and invasion depth for neoplastic lesions in the colon. The first case we present here is that of a 60-year-old woman referred for colonoscopy with abdominal pain and rectal bleeding. Her colon was diverticular and we detected an irregular brownish polypoid lesion within the...

This paper presents PIT, a library for the parallelization of irregular problems on distributed memory architectures. All the strategies underlying the definition of the library can be expressed in terms of operations on a PITree, a parallel version of the tree data structure oriented to irregular problems. We consider the application of PIT to two well known irregular problems: adaptive multig...

OBJECTIVES The aim of this study was to evaluate the safety and improvement in quality of life using 10 mg and 5 mg daily doses of mifepristone for the treatment of uterine fibroids. DESIGN The research was a randomized double-blind clinical study undertaken at the Eusebio Hernández Hospital in Havana, Cuba. SUBJECTS AND METHODS Seventy subjects with symptomatic uterine fibroids took one da...

Departures from a regular texture pattern can happen in many di erent dimensions. Previous related work has focused on faithful texture synthesis for near-regular texture departing along the color and intensity axes while the underlying geometric regularity is well preserved. In this paper, we address the issue of faithful texture synthesis for textures that have both the structural and color/i...
