College students' views on suicide.

College students were asked to rate the acceptability of suicide for themselves and for others in various circumstances. It was hypothesized that acceptability would vary as a function of circumstance of the suicide, the students' religious affiliation, history of past attempts, and whether the suicide was contemplated for oneself or another. The authors found that the highest acceptability for suicide was in the circumstances of terminal or chronic illness and depression. Students affiliated with organized religion were less accepting of suicide than were the individuals without such an affiliation. Previous suicide attempts were associated with greater acceptance of suicide for oneself or for others. In general, participants were more likely to accept suicide for others than for themselves, but the individuals who had previously attempted suicide displayed the opposite pattern under the circumstance of depression. Implications of these findings and directions for further research are discussed.

Computed tomography of pyonephrosis.

Computed tomographic (CT) findings of 17 pyonephrotic and 20 uninfected hydronephrotic kidneys were reviewed. Parameters evaluated included: renal pelvic wall thickness (none; grade 1, < or = 2 mm; grade 2, 3-5 mm; and grade 3, > 5 mm), renal pelvic contents, parenchymal, and perirenal findings. All patients underwent subsequent percutaneous nephrostomy within 1 week of CT. Common CT findings suggesting pyonephrosis include increased pelvic wall thickness and more severe perirenal fat changes than are seen in uninfected hydronephrosis. However, for any one patient, these findings are often not diagnostic. The presence of clinical signs of infection with hydronephrosis on CT is a more sensitive indicator of pyonephrosis than most CT findings.

Gastric uptake of Tc-99m MDP in a child treated with isotretinoin.

The side effects of prolonged isotretinoin therapy include progressive calcification of ligamentous and tendon insertions, premature fusion of epiphyses, and modeling abnormalities of long bones. Increased calcification of gastric mucosa has been reported only in animal studies, but not in humans. A case of a child who was treated with isotretinoin for 26 months for a dermatologic disorder and who showed abnormal gastric uptake of 99m-Tc MDP on a bone scan is reported.

Differential diagnosis of fat-containing lesions with abdominal and pelvic CT.

Recognition of fat within an organ or lesion on abdominal and pelvic computed tomographic scans is an important clue to guiding a differential diagnosis. A systematic approach to these lesions, including a patient's age and clinical history, along with the appearance and location of the lesion often allows a specific differential diagnosis. The anatomic sites of origin for these lesions are the gastrointestinal tract, genitourinary system, and retroperitoneum. Some of the more common entities include various forms of fatty change in the liver, fibrofatty mesenteric proliferation in Crohn disease, ovarian dermoids, and herniations of abdominal fat. In addition, pitfalls such as pathologic processes engulfing normal fat (eg, perirenal abscess) and iatrogenic incorporation of normal fat (eg, omental packing in liver lacerations) should also be included in the differential diagnosis. Familiarity with certain benign occurrences, such as focal fat in the liver adjacent to the falciform ligament and lipomatous infiltration of the ileocecal valve, obviates invasive diagnostic procedures.

The clinical spectrum of ascites associated with maintenance dialysis.

Among 197 patients being treated with maintenance dialysis, six were found to have ascites. Unlike previous reported series, the cause of ascites and the clinical course were variable. Two patients responded to definitive therapy directed against the specific cause. No consistent association was found with the etiology of renal disease or therapy of uremia including the duration of hemodialysis or prior peritoneal dialysis. Nonspecific therapy attempting to alleviate ascites was unsatisfactory. Severe hypertension was not characteristic and bilateral nephrectomy did not influence the course. An extensive diagnostic evaluation is recommended along with skepticism before declaring that idiopathic, refractory ascites exists signaling progressive deterioration.
