Prognostic interest in discriminating muscularis mucosa invasion (T1a vs T1b) in nonmuscle invasive bladder carcinoma: French national multicenter study with central pathology review.

Purpose: Predictive factors of T1 nonmuscle invasive bladder cancer evolution that could guide treatment decision making are lacking. We assessed the prognostic value of muscularis mucosa invasion in nonmuscle invasive bladder cancer.

Materials And Methods: In a national multicenter study patients with primary T1 nonmuscle invasive bladder cancer were recruited from 6 French hospitals.

[T1 bladder carcinoma: prognostic value of the muscularis mucosae invasion (T1a/T1b). A multicenter study by the French Urological Association (CCAFU)].

Objective: The aim of this multicenter study was to determine the prognostic value of the depth of invasion of lamina propria and more specifically the influence of the invasion of the muscularis mucosae on survival parameters in T1 bladder carcinoma.

Patients: Six urological centers included patients between 1994 and 2004 who had an initial T1 bladder tumor. All T1 tumors were substaged according to the muscularis mucosae (MM) invasion into T1a (no invasion beyond the MM) and T1b (invasion beyond MM but preserving the muscle).

[Endometrial and endocervical lesions associated with pseudomyxoma peritonei: a case report].

The association of a pseudomyxoma peritonei with a mucinous tumor of the appendix and/or the ovary is regularly reported in the literature. However, in this context, endometrial or endocervical lesions remain exceptional. We report the case of a 57-year-old patient, with pseudomyxoma peritonei associated with a low-grade mucinous neoplasia of appendix and both ovaries.

The utility of a nebulised intra-tracheal rat model of invasive pulmonary aspergillosis.

Invasive pulmonary aspergillosis (IPA) is of particular concern to immunodeficient patients, whose mortality rates may exceed 80%. The development of an animal model that faithfully reproduces the pathophysiology of IPA would improve the studies on diagnostic and therapeutic modes, and the use of rats as a possible model for IPA seems to have been largely overlooked. Such a model could be established with the MicroSprayer IA-1B.

Transient global amnesia caused by painless aortic dissection.

Neurological syndromes secondary to acute aortic dissection (AAD) are uncommon and usually consist of focal deficits after an embolic cerebral infarction. This article reports the observation of an AAD with the chief complaint of transient acute memory impairment-that is, a non-usual stroke-like symptom.
