Anterior sacral meningocele is a rare congenital meningeal cyst herniating through a bony defect in the sacrum. Since its description by Bryant in 1837, only 154 cases have been reported in the world literature. The application of ultrasound and C.T. scan following myelography is discussed.
180 patients with end-stage renal disease (ESRD) on maintenance dialysis and those who had undergone renal transplantation were questioned retrospectively. 14 patients had consumed excessive quantities of analgesics (greater than 1 kg) prior to the institution of long-term dialysis or transplantation. Sonographic examination done on these patients indicated that 7 had renal papillary necrosis (RPN). The sonographic features were renal papillary calcifications surrounding the central sinus in a complete or incomplete garland pattern. In 5 of these patients RPN is attibutable to the excessive consumption of paracetamol. We have earlier reported 10 cases of RPN due to excessive consumption of paracetamol. Thus 15 cases of RPN attributable to paracetamol consumption (1.0-15.3 kg over a period ranging from 3 to 23 years) have been documented. It is concluded that paracetamol may assume an increasingly important role in the causation of analgesic nephropathy (AN) and ESRD.
