[Diagnostic imaging of intestinal invaginations in the adult. Report of 9 cases].

Adult intestinal intussusception affects the distal portions of the small bowel and the colon in 90% of cases. As a rule, its nature is neoplastic, its clinical presentation aspecific and its diagnosis is frequently an occasional finding during routine imaging examinations. We report on 9 adult patients with intestinal intussusception. All patients were examined with more than one of the following imaging modalities: radiologic study of the small bowel, barium enema, ultrasonography (US), and Computed Tomography (CT). The first diagnostic suspicion of intussusception was correctly made at US in 5 patients and at CT in 4 patients. At surgery, intussusception sites were the following: jejunum in one case, ileum in two cases, ileocolon in two cases and colon in four cases. CT correctly detected lesion site in all the patients who underwent it as the first diagnostic step, while US missed lesion site in one case. Pathology diagnosed a hamartomatous jejunal polyp, a lymphomatous ileal polyp, a lymphomatous polyp of the ileocecal valve, four cecocolonic adenocarcinomas and a left colic lipoma. Lesion nature was suspected at US in one case of ileal lymphoma, while CT suggested the presence of lipoma in one case of ileoileal intussusception. Our experience shows that intussusception can be diagnosed not only with conventional radiologic modalities, but also with US and CT, which are useful to depict both the lesion and its site and extent.

[Acute myocardial infarct in infants].

A retrospective study was made of 6 children, with nonsurgical-related acute myocardial infarction (AMI), between January 1987 and December 1994. The ratio for gender was 1 and mean age at AMI was 49 days, 4 cases being associated with congenital heart disease (Fallot's tetralogy, truncus arteriosus and DiGeorge syndrome, one case each, and anomalous origin of left coronary artery, 2 cases). Kawasaki disease and coronary embolisation from thrombosis of the renal vein occurred in the other 2 cases respectively. All developed congestive cardiac failure and cardiomegaly. In the ECG pathologic q waves with more than 35 msec occurred in all, and QT prolongation occurred in 3. Five children (83%) all with AMI in the anterior and lateral wall of the left ventricle died, death being related with cardiac mechanical failure and not with arrhythmias.

[Diagnostic approach to acute laryngeal trauma: role of computerized tomography].

Aim of this study was to assess the role of Computed Tomography (CT) in the management of acute laryngeal injuries by reviewing our 5 years' experience. From January, 1991, to November, 1996, sixteen patients with blunt trauma and 2 patients with penetrating injuries of the larynx underwent physical examination, laryngoscopy and CT; 2 of them underwent angiography too. The patients were divided into 3 groups according to Schaefer classification [13], first on the basis of physical examination, CT and laryngoscopy findings. The definitive group and therapy were decided on the basis of final spatial assessment. Physical examination diagnosed the presence and the anatomical level of laryngeal injuries in group I (4 patients); laryngoscopy and CT depicted the type of injury and suggested conservative management in 100% of cases. In group II (10 patients), conservative management was suggested by CT findings in the laryngeal, submucosal soft tissues and fascial plane injuries in 100% of cases. Physical examination findings were correct in 30% of cases, questionable in 30% and incorrect in 30%; the exam was not performed in 10% of cases. Finally, laryngoscopy findings were correct in 60% of cases, incorrect in 20% and not diagnostic in 20%. In group III (2 patients), exposed laryngeal injuries required immediate surgery. In group II, the selective application of CT was useful for assessing the degree of damage in 100% of cases and was helpful in planning conservative management. CT avoided surgery in one patient, showed laryngeal cartilaginous features in 2 patients and 2 pseudoaneurysmal injuries not suspected on the basis of physical examination findings.

[The factors triggering epileptic crises according to patients].

The authors were interested in knowing what epileptic patients think about seizure-inducing factors; whether they are convinced that their seizures are induced by any trigger factor and, if so, which factor it is. While mainly interested in the psychological reality of patients, data about objective factors could emerge from this study. An inquiry was made among the 1005 patients who attended the outpatient clinic for epilepsy of Santa Maria Hospital, Lisbon, during five months of 1994. Of the 308 that answered the inquiry, 147 could not recognise any inducing factor for their last seizure, while 144 mentioned such a factor (of the latter, some mentioned two or more factors acting together). Emotional factors were most often mentioned. Seventeen answers were discarded. In many instances, seizure-inducing factors are identified by the patients but difficult to objectivize by investigators, namely those of emotional type. Answers given by the patients might help doctors to provide patients with better care.

[The withdrawal of antiepileptic medication].

Discontinuation of anti-epileptic drugs in patients who have been seizure-free for several years is an important decision due to their toxicity, the long-term use of these drugs may have adverse effects on systemic and/or neurologic functions. The point is how to predict from among the patients those who will achieve remission, and when, and those who will continue to have recurrent seizures despite all treatment. To achieve this goal an index to predict the recurrence risk was developed. Therapy must be reduced slowly and, on polytherapy, only one drug at a time.
