RESUMO
Scorpionism is an endemic public health problem in Mexico [Hoffmann, C.C., 1936. La distribucion geografica de los alacranes peligrosos en la Republica Mexicana. Bol. Inst.

In this prospective study, we assess cardiovascular disorders in children via electrocardiographic (ECG) recordings following envenomation by scorpion species Centruroides limpidus tecomanus found in the state of Colima, Mexico. We analyzed 113 cases between the ages of 5 and 14 years. Among the most frequent symptoms presented included local pain (99.1%) and paresthesia (75.2%), pruritus (36.3%), sialorrhoea (35.4%), and nystagmus (24.8%). Cardiovascular disorders were observed in 39.8% of cases, 71% of which were rhythm abnormalities. We find a significant association between the frequency of ECG alterations and age, whereby 8-9-year-old children are more likely to experience ECG alterations when compared with other tested age groups.

A case of hypopharyngeal lipoma is reported and the fundamental role of C.T. in the diagnosis of laryngo-pharyngeal neoplastic pathologies is emphasized. Laryngoscopy made it quite easy to detect the lesion, showing the smooth surface of a large tumor, although it proved difficult to explore the lower portion because of the narrowing of the larynx. Thermography showed a hypothermia area in the right neck region but did not offer any further information. Only C.T. made correct identification of the site and extension of the lesion possible. It was also possible to identify its fat composition, as suggested by the typical density pattern. The tumor presented a homogeneous hypodense structure and its limits were well defined throughout their entire extension. Furthermore, it was possible to rule out any macroscopic infiltration of the adjacent cartilaginous surfaces of the larynx. The latter feature was confirmed by the C.T. images obtained after intravenous administration of an iodine contrast medium and was consistent with the hypothesis of a benign lesion. Thus the lesion could be considered a lipoma; a highly uncommon non-epithelial tumor of the hypopharyngeal region but which occurs more frequently than liposarcoma. Nonetheless, such C.T. tissue characterization requires histological support so as to prevent distinguishing a well differentiated liposarcoma only after recurrence. The greatest likelihood for accurate diagnosis lies in complete utilization of the data derived from the entire diagnostic procedure. The direct laryngoscopy of the lesion is very important as it makes it possible to inspect the surface and first evaluate any anatomo-pathological alterations. Nonetheless, the most extensive information is provided by C.T.(ABSTRACT TRUNCATED AT 250 WORDS)

A retrospective study is reported which took place over 3 years (1986-1989) and included 99 patients (57 men and 33 women, age range 8-90 years) with lesions attributable to salivary gland diseases. Patients were examined using CAT and sialographic tests. From an analysis of the results it is clear that sialography retains its importance as a means of diagnosis in inflammatory diseases, calculosis and autoimmune disorders, whereas CAT should be used as the preferential diagnostic test for neoplastic lesions.

Computed tomography (CT) scans have been made on 8 patients with subarachnoid hemorrhage and multiple aneurysms. This technique is useful to show the distribution of blood, to predict the location of the ruptured aneurysms, to avoid the lumbar puncture and at last to give valuable informations on the changes of the brain parenchima in the patient's clinical evolution.

In this study it has been valued the differences between T.C. and "scialography" in the parotid gland cystic lesions. Between 1986 and 1987 we examined 100 patients affected by parotid gland diseases utilizing the two different techniques. In 7 patients we diagnosed cystic lesions of parotid gland. Afterwards we compared the results obtained by T.C. and by scialography.

This is a report of myelography findings obtained in 50 patients with B 15000 (Iopamidol), a new non ionic water-soluble contrast medium. The procedure was easily carried out with a tilting table wired to a TV image amplifier. The dose of contrast medium injected intrathecally was 10 divided by 15 cm3 of a preconstituted solution containing iodine 200 or 300 mg/cm3. There were no accidents or major complications. The myelograms obtained with the test material afforded accurate diagnosis of intramedullary and extramedullary lesions, and signally of intervertebral disk protrusion and hernia.
