Ability and fitness to drive of Parkinson's disease patients.

The authors review reports in the literature on the fitness and ability to drive of neurosurgical patients and subjects afflicted by neurological disorders, before focusing on their own series of 204 idiopathic Parkinson's disease (PD) patients. The study sample comprised 173 men and 31 women (average age 70.6 and 74.2 years, respectively) of whom 51, for various reasons, still drove (albeit only short distances). Different variables were examined (Hoehn & Yahr scale values (of the total group and of the subgroup of active drivers), scores for various clinical diseases, and so on) looking for an association between these variables and the number of accidents incurred by PD patients as compared with the healthy population and with a control group of healthy age-matched subjects (ISTAT data). The need for adequate legislation on driving in PD emerges clearly and recommendations are given on which such legislation might be based.

Elective neurotraumatology and therapeutic strategies in early post-trauma.

The aim of elective neurotraumatology is to outline new and valid therapeutic strategies in early post-trauma in order to obtain a more favourable long-term outcome for cranial and spinal trauma patients than usually achieved with conventional intensive therapies. After a critical review of all drugs and measures currently used for the treatment of damage due to cerebral trauma and a brief mention of new agents still being studied, the results of a retrospective study of 128 patients with severe head injury are reported. For all patients a complete clinical and pharmacological history of their traumatic event, which had occurred from 5 to 14 years before the present evaluation, was available. Eighty-nine had undergone traditional therapies and 39 had been given complementary neuroprotective drugs, variously associated with traditional therapies. There was no statistically significant difference between the groups in terms of the global clinical outcome, (assessed by a 5-point scale: death, worsening, unchanged condition, improvement, recovery), and some sequelae, such as decubitus, impairment of sphincter control, neurological focal deficits and post-traumatic epilepsy. On the contrary, cognitive impairment and depression resulted statistically less frequent in patients who underwent conventional therapies and early complementary neuroprotective treatments than in the controls. In conclusion it would be very interesting to perform controlled clinical studies to confirm these preliminary results and the effectiveness of early neuroprotection on the long-term clinical outcome of patients with severe head injury. The therapeutic approach in early post-trauma is still not completely standardised and the purpose of elective neurotraumatology is to emphasise and promote the importance of such a standardisation.

[Multiple sclerosis. A report of a case treated with thymopentin]. / Sclerosi multipla. Presentazione di un caso trattato con timopentina.

The authors analyse the case of a 58-year-old male suffering from substantially "atypical" multiple sclerosis (MS), both in terms of the late onset and because of some characteristics of the course of disease. The patient was treated with a subcutaneous immunomodulator (thymopentin) at a dose of 50 mg/day in 3-monthly cycles with intervals of 2 months between cycles, for a total of 3 cycles. Instrumental (CAT-NMR) and laboratory (immunological) tests were not significant, whereas others provided complex responses that allowed the presence of a demyelinating syndrome to be ascertained, above all due to the positivity of isoelectrofocusing. Treatment with thymopentin, commenced 12 years after the clinical onset of disease and after numerous cycles of cortisone and ACTH therapy, led to a major improvement in clinical conditions, especially of "sthenia" and movement, with consequent recovery of personal autonomy and working capacity which had previously been totally lost. Immunological tests performed at the end of each treatment cycle showed some slight but interesting modifications in parameters relating to DNA and the percentage of HLA antigens bound to lymphocytes. These findings suggest that the patient's immune system was sensitive to treatment with the thymic hormone responsible for the objective clinical improvement. These results appear to open the way to the possible treatment with immunomodulators.

Angiopathic parkinsonism: does it exist?

The Authors report on 150 cases of patients suffering from Parkinson's disease. The patients represent 8.3% of total parkinsonian patients and are selected on the basis of clinical and laboratory criteria that allow the diagnosis of "angiopathic parkinsonism" as an autonomous entity. Cerebral blood flow alterations in Parkinson's disease and associated dementing symptoms are also discussed. In conclusion, the Authors emphasize the usefulness of recognizing the "angiopathic parkinsonism" in view of therapeutical implications.

Operatory indications and licence of craniostenosis.

On average 0.04% of the population is affected by craniostenosis. It is believed there are anatomo-clinical forms at moderate risk and others at high risk. The neurosurgical indications are very different according to various Authors. The forms at high risk which are caused by an isolated synostosis of the coronal system with brachicephalia are either associated to other synostosis (oxicephalia) or to facial synostosis should always be operated, with various techniques, within the first 6 months of life. Basing on the experience of 3 cases of craniostenosis, deliberately not operated on, followed and controlled for over 20 years from the decision of not to operate, all in excellent general condition both neurological and psychiatric, the Authors consider and discuss the criteria of surgical indications with particular regard to clinical objectivity (implicity disregarding a precise value of the craniometric data).

[Neurotraumatology and post-traumatic epilepsy. Prevention, treatment and long-term follow-up. Barbexaclone + phenobarbital (maliasin) versus diphenylhydantoin, phenobarbital, primidone, carbamazepine]. / Neurotraumatologia ed epilessia post-traumatica. Profilassi, trattamento e follow-up a lunga distanza. Barbesaclone + PB ("maliasin") vs difenilidantoina, phenobarbital, primidone, carbamazepina.

A report is presented on 58 patients (46 males, 12 females) all suffering from post-traumatic epilepsy (PTE) and followed up for a minimum of 1 year to maximum of 23 years after the injury (mean 6.3 years). The type and site of the head injury, the nature of the brain lesions, the time elapsing before the first critical manifestation, the clinical character of the epileptic attacks, EEG, cerebral CAT and RMN data were performed are given for all patients. The therapeutic and prophylactic strategies adopted are then described in detail with particular emphasis on the use of diphenylhydantoin (DPH) and barbexaclone. The latter drug, used for the last 3 years was found to be particularly useful in the treatment of patients suffering from a post-traumatic psycho-organic syndrome in addition to the PTE.

Segregation analysis of migraine in 128 families.

To test the existence of inherited liability to migraine, formal segregation analysis of family data collected from 128 patients has been performed. Patients were subdivided into three groups in accordance with the presence or absence of migraine in their parents. The results obtained in each group were then compared with those expected on the basis of two different modes of simple Mendelian inheritance, namely autosomal dominant and autosomal recessive transmission. Our data show that neither of the two hypotheses can be accepted, thus suggesting the existence of a possible genetic heterogeneity of liability to migraine.

CT scan in a case of progressive generalized dystonia with amyotrophic paraplegia.

In a case characterized by progressive generalized dystonic paraplegia with amyotrophy and mental deficiency, CT scanning shows a bilateral lenticular nucleus hypodensity. A similar picture can be found in Wilson disease. However, this patient presented no biochemical, hepatic or ocular abnormalities.

Menstrual migraine: intermittent prophylaxis with a timed-release pharmacological formulation of dihydroergotamine.

An open study was performed on 20 women between 20 and 40 years of age in order to assess the effectiveness of a slow-release pharmacological formulation of dihydroergotamine in the prevention of menstrual migraine. Therapy was started two days prior to the expected date of menstruation and continued for five days after the onset of menstrual flow. Trial lasted for five months, four patients suspended the treatment: one because of side effects and three because of "ineffectiveness of drug". In the 16 patients who completed the study, there was a significant reduction both in intensity and duration of migraine compared to the month prior to treatment.

Classification of partial epilepsies according to the symptomatology of seizures: practical value and prognostic implications.

Among 1,000 outpatient epileptics who visited the Epilepsy Center of Bologna consecutively from 1974 to 1978, 596 cases of partial epilepsy (PE) were chosen, representing 62.9% of all cases classified according to the International Classification of epilepsies. Fifty-four of these cases (5.7%) of those classifiable) that were affected by benign infantile epilepsy with rolandic spikes were not analyzed further. The remaining cases were divided up into three groups based on the symptomatology of the seizures: (1) partial elementary epilepsy (PEE), 102 cases (10.8%); (2) partial complex epilepsy (PCE), 332 cases (35%); and (3) partial secondarily generalized epilepsy (PSGE), 108 cases (11.4%). The three groups were compared according to the parameters that distinguish recognized epileptic syndromes, in order to see whether they constitute autonomous nosographic entities. Among the three groups, significant differences did not arise with regard to the incidence of single lesional etiological factors, the age of onset of the epilepsy, the neurological context, and the general features of interictal EEG. PSGE instead differs significantly from the other two forms for the minor severity of the epilepsy at first examination and for its more favorable course: after at least 2 years of follow-up under treatment, the epilepsy appeared to be controlled in 60.6% of the cases with PSGE, in 31.6% of those with PEE, and in 37.5% of those with PCE (p less than 0.05). For those with PE, globally considered, only three parameters have a favorable prognostic value: the brief duration of the epilepsy at the first observation, the rarity of the seizures, and the presence of only one type of seizure.
