MR imaging of corpus callosotomy.
MR findings in 13 patients who underwent corpus callosotomy for medically intractable seizures were reviewed. Preoperative MR studies were available in nine patients: five showed at least one morphological and/or MR signal abnormality including corpus callosal thinning (four cases), cerebellar atrophy (two cases), cortical atrophy (two cases), and periventricular hyperintensity on T2-weighted images (one case). Four patients had normal MR studies. Postoperative MR studies were obtained in 11 patients with subtotal callosotomy and two with total callosotomy. Of all pulse sequences, sagittal T1-weighted images best showed the surgical division, although two cases displayed a coaptation artifact, which was misleading. A surgical clip placed at the posterior extent of the callosotomy was best visualized with sagittal T1-weighted imaging. Two patients (15%) had MR findings consistent with subacute blood in the callosum, and three patients (23%) demonstrated parafalcial hyperintensity on T2-weighted images 1 week after callosotomy. Motion artifact was a significant problem with coronal imaging and T2-weighted pulse sequences in postoperative patients. Patients selected for corpus callosotomy may have a normal baseline MR or show nonspecific abnormalities. MR imaging is an effective method for evaluating callosal division, and in some cases, may demonstrate signal changes consistent with surgically related edema and/or blood.

Stress in IVF workers.
Workers in new and personally exacting health services face particular challenges which are not evident in more traditional areas. IVF workers are involved in such an innovative service. Their perception of workplace stressors has not previously been addressed in the literature. Fifty-nine IVF workers and 32 non-IVF workers (in routine obstetrics and gynaecology) completed a battery of standardized psychological questionnaires on the symptomatology of stress and in addition answered questions on workplace problems and work satisfaction. Reported stress was highest among scientific/technical workers who varied significantly from the control group scores. IVF medical staff showed elevated stress scores, but were not significantly separated from controls, except on state anxiety. Work satisfaction scores were generally high for all IVF professions, except for pay and promotion satisfaction scores which were depressed among nurses and scientific/technical staff. It was concluded that this initial survey had revealed important information about the impact of a new scientific and clinical enterprise upon staff and should promote closer examination of the reasons for such reported stress.
