Seizures induced by thinking.

A patient with generalized convulsions noted that seizures were reliably precipitated by mental arithmetic. The interictal electroencephalogram revealed only a mild, diffuse, nonspecific disturbance, but bursts of generalized epileptiform activity with no obvious clinical expression accompanied efforts at mental arithmetic with a significantly high incidence. Tasks involving multiplication, division, and manipulation of spatial information were significantly associated with discharges, but few, if any, discharges appeared when addition and subtraction tasks of equivalent difficulty were performed. Tasks involving the retention of numerical information in short-term memory (e.g., immediate repetition of a series of 8 digits) were never associated with paroxysmal EEG activity. It is argued that generalized epilepsy of this kind may be related to focal dysfunction in a manner analogous to the involvement of the occipital lobe in cases of pattern-sensitive epilepsy.

Rectal carcinoma with solitary cerebral metastasis: report of a case and review of the literature.

A 54-year-old man underwent abdominoperineal resection for carcinoma of the rectum. Three months later, neurologic signs and symptoms developed. A brain scan, as well as angiographic studies, demonstrated a space-occupying lesion in the right parietal area. A solitary tumor was removed at craniotomy. Histologic examination revealed a metastatic adenocarcinoma with a rectal primary tumor. For two years the patient remained well, but then signs of local perineal recurrence developed. Treatment with cobalt irradiation and chemotherapy was unsuccessful. Autopsy revealed local recurrence with numerous distant metastases; however, examination of the brain failed to show a recurrent metastatic focus.

Cannonball metastases with favourable prognosis.

BACKGROUND: Secondary 'cannonball' metastases to the lung are frequent and usually associated with disseminated malignancy and poor prognosis. AIM: To report the case of a patient with metastatic pulmonary endometrial stromal sarcoma who had a previous hysterectomy for benign uterine fibroids and no past history of malignancy. RESULT: A 70-year-old female presented with cannonball metastases in her lung. Four years previously she had a hysterectomy for 'fibroids'. Review of the original histology revealed endometrial stromal sarcoma, similar to the lung metastasis. She currently has a good prognosis. CONCLUSION: A patient with 'cannonball' metastases can have a favourable prognosis. A female patient with a previous hysterectomy for uterine fibroids, should be considered to have metastatic sarcoma until proven otherwise.

Emergency pulmonary embolectomy.

Pulmonary embolectomy maybe a life saving procedure in the unresponsive hypotensive patient following a massive pulmonary embolectomy despite optimal medical therapy. We report a successful pulmonary embolectomy in a 47 year old patient, three days post post coronary artery bypass grafting (CABG) and a new approach to the problem of caval filters in such patients. This case demonstrates the benefit of early surgery in this life threatening situation.
