Endometriosis of the bladder as a cause of obstructive uropathy.

A 47-year-old woman (gravida 1, para 1) with menorrhagia and pelvic pain was found to have an enlarged fibroid uterus and bladder mass on ultrasonographic imaging. The patient underwent an abdominal supracervical hysterectomy and transurethral bladder mass resection. Histopathologic findings revealed leiomyoma uteri, intramural adenomyosis, and bladder endometriosis. Most case series of bladder endometriosis include women that present with urinary symptoms. This is a rare case of obstructive uropathy secondary to bladder endometriosis in a patient without any urinary signs or symptoms.

Wiping behavior, skin resistance, and the metabolic response to dehydration in the arboreal frog Phyllomedusa hypochondrialis.

Several species of arboreal frogs secrete lipids from cutaneous glands and wipe these secretions over the body surfaces to reduce evaporative water losses. Following wiping, frogs become immobile in water-conserving postures, and some have suggested they are torpid. Here we report wiping behaviors and the physiological correlates of immobile postures in the arboreal monkey frog Phyllomedusa hypochondrialis. Skin resistance to water loss was comparatively high, and rates of evaporation were as low as 4% of that from a free water surface. Standard rates of metabolism (SMR) varied from 89 microL O2 h(-1) at 18 degrees C to 316 microL O2 h(-1) at 34 degrees C and were sensitive to both temperature (T) and body mass (W; mL O2 h(-1) = 0.016W0.642 x 10(0.030T)). The mean SMR did not change significantly during four consecutive days of dehydration when animals lost 19%-34% of body mass. Therefore, it appears these frogs do not routinely depress metabolic rates following wiping. However, some individuals that lost higher percentages of body water exhibited trends of decreasing oxygen consumption, suggesting that suppression of metabolic rates might occur at greater levels of body water deficit or perhaps during a slower course of dehydration than imposed by our experiments (e.g., individuals that are secluded during periods of drought).
