Conditions analogous to an experimental model of hypertension described by Page in 1939 are called "Page kidney." In chronic subcapsular hematoma, the most common clinical counterpart to Page's model of renal parenchymal compression, a review of the literature reveals that hypertension is usually cured by nephrectomy, but is seldom cured by mere evacuation of the hematoma. To our knowledge, no patient remaining hypertensive after evacuation has undergone nephrectomy. In the patient described herein, a liquified subcapsular hematoma reaccumulated after it was drained percutaneously, and therefore it had to be evacuated surgically. Persistent renin-mediated hypertension, however, prompted curative nephrectomy. The response to more prolonged percutaneous drainage might have guided more effective initial surgery.
\s=b\ Although much is known about the virus believed by most experts to be the cause of the acquired immunodeficiency syndrome and about its pathogenic actions, major areas of ignorance remain. Among these are the reasons for the varying time between infection with human immunodeficiency virus and development of acquired imunodeficiency syndrome, the relationship between neurologic and medical aspects of the disease, the time course of neuropsychological findings, and the prevalence of psychiatric morbidity. We assessed 124 homosexual men who were positive for human immunodeficiency virus and 84 who were negative for the virus. In this article we describe the study design, method of recruitment, and medical and demographic characteristics of the cohort, which will be followed up for 5 years.
Two cases of rare pulmonary neoplastic lesions (primary pulmonary artery sarcoma and pulmonary carcinosarcoma) directly involving the pulmonary artery and presenting with findings mimicking acute pulmonary embolism are discussed. Although this represents an unusual presentation for these two lesions, they should be included in the differential diagnosis of acute pulmonary embolism in patients presenting with somewhat atypical clinical, isotopic, and radiological features. Serial lung scans followed by angiography will prove useful in arriving at the correct diagnosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
