Surgical treatment under general or regional anesthesia is not suitable for high-risk elderly patients who seek minimally invasive management. Unfortunately, for patients who are not fit for transurethral and/or laser prostatectomy, few treatment options remain, other than long-term catheterization and insertion (under local anesthesia) of a prostatic stent.

Pseudomembranous Trigonitis: A Common but Underrecognized Urological Entity

Abstract: Pseudomembranous trigonitis is the term used to describe squamous metaplastic changes of the bladder trigone, which affect nearly 40% of adult females. We present the characteristics of this underrecognized clinical entity and encourage further relevant research. 1. Introduction Pseudomembranous trigonitis is the term used to describe squamous metaplastic changes of the bladder trigone [1]. Such changes are present in up to 40% of adult females (<5% in men) [1]. It was first described in 1905 by Heymann as “cystitis trigoni” and since then several terms have been used, reflecting continuing uncertainty upon this common entity [2]. Herein, we highlight the characteristics of pseudomembranous trigonitis according to the relevant literature with the objective of increasing clinical suspicion. 2. Etiopathogenesis Squamous metaplastic changes of the trigone are observed usually in adult women of childbearing age [3]. These squamous changes of the trigone are nonkeratinizing, in contrast with the keratinizing squamous changes of leukoplakia, which are detected elsewhere in the bladder and require regular followup cystoscopy (as a potential precursor of squamous cell carcinoma) [3, 4]. It has been demonstrated that pseudomembranous trigonitis in women develops under hormonal impact while the metaplastic urothelium undergoes cyclical menstrual changes similar to the vaginal epithelium. Pacchioni et al. [5] performed estrogen and progesterone receptor assays in fresh frozen and paraffin embedded bladder biopsies. Estrogen receptors were identified only in the trigone in relevance with squamous metaplasia. A clear correlation between the presence of steroid receptors at the squamous metaplasia of the trigone was demonstrated. Interestingly, men receiving estrogen therapy develop squamous metaplasia of the penile urethra. Russell et al. [6] studied 21 transsexual men who received oestrogens prior to gender change surgery. Histological examination of the removed anterior penile urethra revealed squamous metaplasia in 15 cases (71%). It seems that the trigone has an embryological derivation distinct from the remainder of the bladder, allowing the trigonal urothelium to respond to estrogenic stimulation [7]. Bacteria cystitis has been associated with the development of pseudomembranous trigonitis, especially in cases of recurrent urinary tract infections [1, 8]. There seems to be a link between pseudomembranous trigonitis and recurrent urinary tract infections (UTIs). The fact that patients suffering from recurrent UTIs benefit by oestrogen therapy may be linked to

Immunopathology of giardiasis: the role of lymphocytes in intestinal epithelial injury and malfunction
Buret, AG;
Memórias do Instituto Oswaldo Cruz , 2005, DOI: 10.1590/S0074-02762005000900032
Abstract: t lymphocyte-mediated pathogenesis is common to a variety of enteropathies, including giardiasis, cryptosporidiosis, bacterial enteritis, celiac's disease, food anaphylaxis, and crohn's disease. in giardiasis as well as in these other disorders, a diffuse loss of microvillous brush border, combined or not with villus atrophy, is responsible for disaccharidase insufficiencies and malabsorption of electrolytes, nutrients, and water, which ultimately cause diarrheal symptoms. other mucosal changes may include crypt hyperplasia and increased infiltration of intra-epithelial lymphocytes. recent studies using models of giardiasis have shed new light on the immune regulation of these abnormalities. indeed, experiments using an athymic mouse model of infection have found that these epithelial injuries were t cell-dependent. findings from further research indicate that that the loss of brush border surface area, reduced disaccharidase activities, and increase crypt-villus ratios are mediated by cd8+ t cells, whereas both cd8+ and cd4+ small mesenteric lymph node t cells regulate the influx of intra-epithelial lymphocytes. future investigations need to characterize the cd8+ t cell signaling cascades that ultimately lead to epithelial injury and malfunction in giardiasis and other malabsorptive disorders of the intestine.
Desarrollo de la Misión Milagro en Venezuela

Abstract: the mission miracle, a cuban initiative supported by venezuela, is one of the social and humanitarian campaigns aimed at recovering the vision or curing several eye diseases of the latin american people. due to the pending debt with those persons excluded from the health care and separated from the social and productive life because of visual health problems that can be solved, it is deem necessary to evaluate the development of the mission miracle in venezuela. an exploratory study was conducted on this topic based on the analysis of documents and published articles. the mission miracle in venezuela has given the vision back to 668 844 latin americans cared by cuban and venezuelan specialists. the mission miracle is a real and efficient latin american integrating mechanism of struggle against poverty and social exclusion, with big social impact since it has provided better quality of life to thousands of venezuelan and other latin american people.
Hyponymy In Hausa

Abstract: Words\' meaning in languages relate to one another when the senses, ideas, and thoughts become associated. One way in which they can be associated is through inclusion of one meaning into another. A word\'s meaning that encompasses other meaning assumes the position of a general meaning, distinguishing itself from a specific one which essentially become inclusive. Hausa language is naturally far more to show an appreciable relationship between a word\'s general meaning and its specific than other languages. Besides the hierarchical relation of words\' meaning, Hausa words can also be seen to have an associate relationship of meaning. It may be even be undoubted that socio-linguistic accounts for this usage. The Information Manager Vol. 7 (2) 2007: pp. 8-13
