Corticograms of the mesial structures of the temporal lobe may be obtained with the recently developed foramen ovale electrodes. Since their installation is easy and of low risk, they will probably displace other invasive techniques routinely used up to the moment for the localization and lateralization of epileptic foci originated in the temporal lobe. For the first time in our country, we have used this technique in 7 patients with medically intractable complex partial epilepsy.

[Anorectal pain].

Arq Gastroenterol

December 1993

The aim of the present study is bring to the colo-proctologists and clinicians the importance of the correct interpretation of ano-rectal pain. Sometimes this pain is so characteristic that it becomes pathognomonic of some diseases. The authors detail the rectal and anal canal innervation and distinguish 2 opposite types of pain in this region: a cutaneous or superficial and a visceral or deep pain.

We retrospectively analyzed the presence of sharp waves in 2-h EEGs performed 6 months after epilepsy surgery in 59 patients. To study the significance of the postoperative interictal epileptiform activity in the tissue remaining after resection, we included only patients with a single epileptic focus (as defined preoperatively by prolonged video/EEG recordings and subdural electrode arrays studies) and no progressive structural lesions. Temporal lobectomy was performed in 51 patients (86%); extratemporal resections were performed in the remainder.

A full-length tomato cDNA clone, TSW12, which is developmentally and environmentally regulated, has been isolated and characterized. TSW12 mRNA is accumulated during tomato seed germination and its level increases after NaCl treatment or heat shock. In mature plants, TSW12 mRNA is only detected upon treatment with NaCl, mannitol or ABA and its expression mainly occurs in stems.

Language interference was elicited by electrical stimulation of the dominant basal temporal region in 8 out of 22 cases and in none of 7 cases with subdural electrodes implanted over the nondominant temporal lobe. Language interference was elicited by stimulation of electrodes placed over the fusiform gyrus 3-7 cm from the tip of the temporal lobe. Electrical stimulation of the basal temporal language area produced a global receptive and expressive aphasia with speech arrest at high stimulus intensities.

The main contamination areas in Goiânia were exposed soil surfaces, and with the first rainfalls, 137Cs quickly reached the Meia-Ponte River, the main local waterway. Regular measurements of bottom sediment, surface water, and fish were begun 3 wk after the accident. In the first survey, 137Cs was detectable in sediments up to 12 km downstream from the accident area.

In September 1987, a powder radioactive source was removed from a teletherapy machine in Goiânia, Brazil. Subsequently, it was ruptured in a residential garden causing the dissemination of 137Cs throughout the city. Soil resuspension processes and burial of contaminated house waste in unused gardens were the major contributors to the Cs dissemination in soils at the secondary contaminated sites.

The pharmacological treatment of hypertension raises not only the dilemma of the election of the most suitable drugs given to each patient, but also that of an effective control of the antihypertensive effect as well as undesirable reactions, including an accentuated hypotension. Continuous ambulatory monitoring (CAM) is an effective form of diagnosis and therapeutic control of hypertension. In order to evaluate the efficacy and tolerance of a new concentration of diltiazem (240 mg) in tablets of sustained release, for a single daily intake, a double blind, randomized, crossed study with placebo, was performed in 20 patients with mild to moderate hypertension and a positive ergometric test.

Based on the inexistence of references in Brazilian and International literature of the association polymyositis, myasthenia gravis and thymoma in a young male adult, the authors propose to describe one case presenting the associated syndrome. The disease began when the patient was 22 years old, being the climax of its clinical expression four years later. It is emphasized the difficulty on the differential diagnosis between polymyositis and myasthenia gravis, once these diseases frequently have their clinical manifestations well individualized.

In a study of 197 cases of histologically confirmed invasive cervical cancer, 61% of biopsies were positive for human papillomavirus (HPV) DNA by Southern or dot-blot hybridization. An association between detection of HPV DNA and oral contraceptive use was observed when HPV-positive and -negative cases were compared. Women reporting recent or long-term (greater than 4 yrs) oral contraceptive use were at 2.

Eighty-eight patients had bilateral intracarotid amobarbital (Wada) testing to determine hemispheric dominance for language in preparation for epilepsy surgery, as well as unilateral extraoperative cortical electrical stimulation using subdural electrode arrays. In none of the patients with left dominance by Wada testing were language areas found with right-sided stimulation, but two patients with right dominance by Wada testing had language areas mapped on the left side. These findings suggest that left dominance by Wada testing is strong evidence for exclusive lateralization of language function in the left hemisphere, but there is concern about the ability of the Wada test to exclude the possibility of some left-sided language function despite apparent right-sided dominance.
