Psychosomatic study of 60 patients with vertigo.

The authors examined 60 consecutive patients hospitalized in Modena University Otorhinolaryngological Clinic for vertigo by means of an interview and of three self-rating scales (Zung's SDS, SAS and the Middlesex Hospital Questionnaire). The control group was composed of an equal number of patients hospitalized in the same ward and period for different nonsurgical otiatric diseases; the two groups were matched for age, sex, residential area, sociocultural conditions, duration of hospitalization and disease. According to the clinical diagnosis carried out when discharged from hospital, the patients where divided into five groups (Ménière's disease, neuronitis, vertebrobasilar insufficiency, neurosensorial deafness, nucleoreticular syndrome of Ararslan).

Dizziness and headache.

Dizziness and headache have been known to be associated in both adults and children, since early this century. Otoneurological examination of headache sufferers at the University of Modena Headache Centre revealed a high percentage of ENG alterations indicating a mainly bulbo-pontine vestibular disorder. The lesion, which is more significant on the side more affected, is modified during attacks and with time.

Computed tomography in the management of spinal cord arteriovenous malformations.

This is a report of two cases of intramedullary arteriovenous malformations (AVMs) where computed tomography (CT) was used as a complementary diagnostic investigation. CT scan features in these two cases are briefly discussed.

Survival and significance of PNH erythrocytes: a scanning study.

The SEM study of PNH erthrocytes which survived incubations with decreasing dilutions (from 1:640 to 1:20) of fresh compatible serum in isotonic sucrose has indirectly evidenced that spherocytes and spherostomatocytes are the most sensitive population to the complement lytic action; swelling is an osmotic consequence of their membrane hypersusceptibility. In such functional abnormality the swollen red cells are closely followed by the cribrous and pitted erythrocytes. A relationship has been found between percentage of the swollen cells and frequency of PNH haemolytic bouts: these are most likely to occur when spherocytes and spherostomatocytes are above 40% of cells.
