A Case of Disabling Urinary Frequency and Pelvic Pain Due to Postoperative Uterine Adhesions.

Introduction: Dense lower abdominal adhesions are known to cause urinary frequency by restricting expansion of the bladder. However, since preoperative diagnosis of adhesions has been difficult and there are multiple other causes of urinary frequency, such patients may go undiagnosed. With the improving resolution of ultrasound, ever smaller pathologic structures may be visualized, particularly if they are considered in the differential diagnosis.

Effects of methylmercury exposure on the behavior of captive-reared common loon (Gavia immer) chicks.

Behavioral effects resulting from exposure to dietary methylmercury (MeHg) have been reported in studies of several wildlife species. However, quantifying the impact of contaminant exposure on wild populations is complicated by the confounding effects of other environmental stressors. We controlled confounding stressors in a laboratory study to quantify the level of dietary MeHg exposure associated with negative effects on the fitness of captive-reared common loon (Gavia immer) chicks.
