Fraley's syndrome: case report and update on current diagnostic methods.

A 38-year-old woman presented with fever, right flank pain, and a clinical diagnosis of pyelonephritis. Work-up revealed the presence of a crossing arterial branch causing obstruction of the superior infundibulum of the right kidney, which is an uncommon cause of nephralgia and urinary infection initially described by Fraley in 1966. Intravenous urography, retrograde pyelography, and angiography remain the mainstay of diagnosis, much as in the initial descriptions of this entity. [131I]Hippuran imaging, with analysis of the upper and lower pole regions of interest, provides a simple yet powerful method of evaluating functional and excretory changes in the superior infundibulum, and has proved more efficacious than previously reported whole-kidney renograms. Renal scintigraphy represents a relatively noninvasive method of serial functional examination in this disorder. Ultrasound imaging, by monitoring upper-pole dilatation, may provide complementary morphologic information important for long-term follow-up.

Uterine artery Doppler velocimetry in pregnant women with hypertension.

Uterine and umbilical artery velocimetry was carried out on 71 women with hypertensive disorders in pregnancy. Three categories of hypertensive disease were diagnosed: chronic hypertension, preeclampsia, and chronic hypertension with superimposed preeclampsia. Clinical classifications describe the severity of disease effectively, primarily because the classification is based on the appearance of abnormal physical or laboratory findings. Doppler velocimetry of the uterine arteries shows that normal pregnancy occurs when the systolic/diastolic ratio is less than or equal to 2.6. When the ratio exceeds this level and there is a notch in the waveform, the pregnancy is complicated by stillbirth, premature birth, intrauterine growth retardation, and maternal preeclampsia. The positive and negative predictive value of the examination is 93% and 91%, respectively. It appears that this new technology will be an essential ingredient of optimum pregnancy surveillance.

Infantile seizures caused by voluntary water intoxication.

A case of infantile seizures of unusual etiology and presentation is described. Water intoxication with resultant epilepticus was caused by ingestion of nearly 150 ml/kg of fresh water on the day of presentation. It is unclear why the infant voluntarily consumed so much water, but heat illness is the most probable cause.

Sonography and computed tomography in the diagnosis of carcinoma of the gallbladder.

The computed tomographic and sonographic findings of 26 patients with gallbladder carcinoma were reviewed, and the problems and pitfalls encountered with these imaging techniques are discussed. The most common finding, a mass filling or replacing the gallbladder, was seen in 42% of the patients. A mass protruding into the gallbladder was seen in 23%, and diffuse asymmetric thickening of the gallbladder wall in 15%. Recommendations are made to avoid some of the diagnostic problems encountered. With careful and meticulous technique early carcinoma of the gallbladder may be detected with greater frequency by cross-sectional imaging techniques.
