Henoch-Schönlein purpura presenting with orchitis: a case report and review of the literature.

Henoch-Schönlein purpura (HSP) is the most common cause of nonthrombocytopenic purpura in children. The clinical picture is classically a cutaneous purpuric eruption of the legs and buttocks and infrequently the upper torso and extremities. Arthritis, gastrointestinal tract symptoms, and nephritis are other common findings typically associated with the cutaneous findings.

Conservative management of a bleeding renal angiomyolipoma in pregnancy.

Background: Bleeding angiomyolipomas in pregnancy are rare but may be devastating and potentially fatal. In previous cases, most of these lesions have been managed with urgent nephrectomy or embolization. Only one other case report describes treating these lesions through conservative management and vaginal delivery.

Early molecular changes in bladder hypertrophy due to bladder outlet obstruction.

Objectives: To determine the temporal relationship between the increase in bladder mass and the expression of growth-associated gene products during bladder hypertrophy due to partial bladder outlet obstruction.

Methods: Adult female rats, subjected to partial bladder outlet obstruction, were killed at defined points, and their bladder weight and total protein were determined and compared with sham-operated and nonoperated controls. Hyperplasia was determined by the expression of proliferating cell nuclear antigen, transcription factors, and cyclins in obstructed rat bladders.

Testicular torsion in an adolescent with Fragile X Syndrome.

Fragile X syndrome (FraX) is the most common hereditary form of mental retardation. The clinical syndrome includes mental retardation, macroorchidism, and typical but variable facial features. Although macroorchidism has been recognized as a cardinal feature of FraX, descriptions of testicular pathology are rare.

Routine radiologic surveillance for obstruction is not required in asymptomatic patients after ureteroscopy.

Objective: A retrospective medical record review was performed with the goal of determining the need for radiologic evaluation after ureteroscopy.

Patients And Methods: Of 183 patients undergoing ureteroscopic procedures at our institution between 1989 and 1993, 131 underwent postoperative radiologic studies capable of diagnosing ureteral obstruction. Of these patients, 110 (84%) were asymptomatic after the procedure, and radiologic procedures capable of displaying obstruction were performed at a median of 60 days (mean 73 days; standard deviation 189 days) after ureteroscopy.
