Primary lymphoepithelioma-like carcinoma of the urinary bladder: report of one case with review and update of the literature after a pooled analysis of 43 patients.

Background And Objectives: Lymphoepithelioma-like carcinoma (LELC) is an undifferentiated epithelial tumor with a dense inflammatory infiltrate that resembles the lymphoepithelioma of the nasopharinx occurring in other sites. Primary LELC of the bladder (LELCB) was first reported by Zukerberg et al in 1991. The incidence of LELCB is 0.

Vesicouterine fistulas following cesarean section: report on a case, review and update of the literature.

Herein we report on 1 more case of vesicouterine fistula following cesarean section with review and update of the literature concerning this unusual topic. The disease presented with vaginal urinary leakage, cyclic hematuria and amenorrhea. The fistula was successfully repaired by delayed surgery.

Detection of bladder cancer by semi-automated microsatellite analysis of urine sediment.

Patients with transitional-cell carcinoma (TCC) require careful follow-up due to the high risk of recurrence. Cystoscopy and biopsy are reliable but invasive, while urine cytology is plagued by low sensitivity. It has recently been shown that allelic abnormalities detected by microsatellite analysis of DNA extracted from urine can be used to diagnose TCC with high reliability.

[Preemptive analgesia or balanced periemptive analgesia?].

"Preemptive analgesia" means that analgesia given before the painful stimulus prevents or reduces subsequent pain. The concept of preemptive analgesia originates from basic science and experimental studies. However, in some clinical studies preemptive effect is not always present.

Origin of multikilometer earth- and mars-crossing asteroids: A quantitative simulation.

Orbital dynamic simulations show that many asteroids in the main asteroid belt are driven toward Mars-crossing orbits by numerous weak mean motion resonances, which slowly increase the orbital ellipticity of the asteroids. In addition, half of the Mars-crossing asteroids (MCAs) transition to Earth-crossing asteroids (ECAs) in less than 20 million years. This scenario quantitatively explains the observed number of large ECAs and MCAs.
