Echographic study of follicular maturation and ovulation during the normal menstrual cycle.

Follicular development was followed by echography during 18 menstrual cycles in 10 women volunteers. Results were correlated with changes in serum hormone levels, basal body temperature curves, and cervical mucus changes. The average follicular growth as measured from the time of echographic visualization was 0.3 cm/day. The diameter of the follicle measured the day before disappearance was 2.7 +/- 0.3 cm. In all cases echography was shown to indicate accurately the time of ovulation. Given its inoffensive nature, the usefulness of echography in determining the physical event of ovulation is demonstrated. Possible applications in the surveillance of ovulation induction methods and in artificial insemination are discussed.

Chronographic speech patterns of acutely psychotic patients. A preliminary note.

This study was a preliminary attempt to explore the likelihood that, for psychiatric patients, amount of vocal activity (relative to silence) reflects degree of psychopathology and change with treatment. Five acute schizophrenic patients (two men and three women) were each seen in three interviews by one of two interviewers. After each interview, the interviewer evaluated the extent of his patient's pathology in terms of the Brief Psychiatric Rating Scale, and he and the patient separately completed a questionnaire designed to elicit their perceptions of the interview. The results reveal that the relative amounts of the patients' vocal activity were negatively related to the interviewers' ratings of their general level of psychopathology and were also related to several aspects of their perceptions and the interviewers' perceptions of the interview. However, the number of interviews per patient was too few to permit an evaluation of treatment effects.

Bilateral complete ureteral obstruction secondary to an abdominal aortic aneurysm with perianeurysmal fibrosis: diagnosis by computed tomography.

The sixteenth case of bilateral ureteral obstruction with anuria secondary to an abdominal aortic aneurysm with perianeurysmal fibrosis is presented. The details of this case clearly indicate the need for a combined vascular and urologic approach to patients with this disorder. A complete preoperative evaluation, including excretory urography, retrograde pyeloureterography, aortography and, when indicated, venacavography, may determine renal and vascular abnormalities that will allow a more definitive and successful management of this difficult problem. Furthermore, we believe that the use of computed tomography is an invaluable tool to define this retroperitoneal disease process and its precise relationship to the ureters.

Liver metastases discovered during high-dose excretory urography.

Liver metastases were discovered in 4 adults during high-dose excretory urography with upper abdominal tomograms. Previous reports in the English literature have noted incidental discovery of hepatic cysts or abscesses during urography, but no documented cases of liver metastases were found. All metastases were visualized as round, lucent, hepatic filling defects during total body opacification. Radiologists performing high dose excretory urography with tomography should routinely scrutinize the hepatogram, because metastases, cysts, or abscesses may be visualized. Final diagnosis of these masses usually depends on additional diagnostic modalities.

Primary amyloidosis of urinary bladder and ureter: cause of mural calcification.

Primary amyloidosis is seen in the absence of predisposing disease. It may affect most organs in the body, including the collecting system of the urinary tract. Submucosal calcifications have been described in the renal pelvis and may be pathognomonic for primary amyloidosis of the renal pelvis. We have been able to demonstrate similar submucosal calcifications in the ureter and bladder. The differential diagnosis of submucosal calcification of the distal ureter and bladder must include bilharziasis and tuberculosis. With the recognition of submucosal calcifications, diagnosis of the underlying disease may be readily made. An illustrative case is presented.
