RESUMO
Morton's neuromas, though usually diagnosed clinically, can occasionally be problematic. When required, imaging may be performed via ultrasound or computed tomography, though the former can be quite operator-dependent, and the latter exposes the patient to ionizing radiation. Magnetic resonance imaging can be very helpful in certain clinical situations. This case report demonstrates the usefulness of gadopentetate-enhanced magnetic resonance imaging with fat saturation in the evaluation of interdigital neuromas.

To determine whether magnetic resonance (MR) imaging can demonstrate the early stages of osteonecrosis that are not detectable radiographically, the authors compared radiologic findings with histologic results in seven patients at high risk for osteonecrosis of the femoral head. Radiography and MR imaging were performed, and proximal femoral intramedullary pressures were measured in all patients, even if results from imaging studies were normal. If the pressures were elevated, core decompression with biopsy was performed. Seven patients had elevated pressures in 11 hips. Of 11 hips from which biopsy specimens were taken, all had histologic evidence of osteonecrosis. However, in only five were the MR imaging findings consistent with osteonecrosis. In the remaining six hips with osteonecrosis, MR imaging findings were normal. Sensitivity of MR imaging in detection of osteonecrosis was 46%. The authors conclude that normal MR imaging results in high-risk patients do not rule out the presence of osteonecrosis.

Cyproterone acetate was used in the treatment of ten patients presenting with problems of sexual deviancy. Of these six completed the course of treatment over a period of one year and psychological, medical and endocrinological measures were recorded.

The study undertook to compare the efficacy of dibenzepin and amitriptyline in the treatment of endogenous depression. The outcome of the study was that both drugs appear to be equally effective in the treatment of depression, but dibenzepin was more efficient in reducing associated anxiety. Both drugs are appropriate to the treatment of psychotic depression, and work equally rapid. There was also a tendency for dibenzepin to elicit less intense side effects.
