The etiology, frequency and prognosis of recurrent Bell's palsy were studied in patients with peripheral paresis of n.facialis of various etiology. Fourteen (11.9%) of 117 patients with Bell's palsy had a recurrent paresis of n.facialis. Nine of these were of homolateral and five contralateral type. Seven recurrent facial paralyses in idiopathic Bell's palsy (i.e. 10.4% of the patients with idiopathic facial palsy), 3 facial palsies of viral origin (i.e. 8.8% of the patients with viral facial palsy), one in association with diabetes mellitus, one during pregnancy, one combined with positive rheumatic serological tests, and one in a case of Melkersson-Rosenthal syndrome were found. The frequency and heterogenity of etiology of recurrent facial palsies suggest a predisposing factor or immune mechanisms. In eight patients there was within 6 to 8 weeks a good, in two patients a moderate and in four patients a poor recovery of function. The greater reduction of the compound action potential of the m.orbicularis oris in recurrent homolateral facial palsy in relation to patients with single manifestation point out the greater denervation and therefore the poorer prognosis of recurrent palsies. A prophylactic decompression to prevent a third attack of recurrent facial paresis is considered.

Electrophysiological investigations were carried out on 20 healthy controls and 130 patients with peripheral facial nerve paralysis. The aetiology was as follows: idiopathic (Bell's palsy) in 60 cases, viral in 29, traumatic in 18, postoperative in 4, in connexion with chronic otitis media in 6, diabetes mellitus in 4, positive rheumatological tests in 3, disturbed lipid metabolism in 2, the Melkersson-Rosenthal syndrome in 1, as a complication of pregnancy in 2, and in association with a tumour in 1 case. The compound action potential (CAP) of the orbicularis oris muscle was determinedi n 370 occasions in a right/left comparision, the record of the muscle response was intergrated over the time of action (IAR) on 32 occasions and trison of 255 occasions. The normal values are given in the first place and their dependence of the age of the subject. Then, the prognostic sifnficance of the above-mentioned parameters is investigated in cases of peripheral facial nerve paralysis. It is apparent that the determination of the CAP in a right/left comparison is a valuable prognostic guide as early as the 4th day, insofar as a decrease in this parameter of under 50% can be interpreted as a favourable sign and satisfactory reversal of the paralysis can be expected within 6-8 weeks. By contrast, a decrease of over 70% in the CAP is a bad prognostic sign, indicative of presumably only a poor trend to reversal of the paralysis. An intermediate depression of the CAP in the range of 50-70% signifies an expected moderate recovery within 6-8 weeks ahe case of CAP determination at the time of maximum amplitude depression (as opposed to the 4th day), then a decrease of less than 70% is taken to be indicative of satisfactory functional recovery within 6-8 weeks; a decrease of 95-100% signifies a bad prognosis, whilst a decrease amounting to between 70 and 95% carries an uncertain prognosis. The maximum decrease in amplitude was registered on the 8th day on average; the range lay between the 4th and the 14th day. An exception to these figures was the delayed response of the CAP in the case of 6 patients, 5 of whom showed a maximum decrease during the 3rd week and the last patient as late as the 4th week following the onset of facial nerve paresis. Similar reliance can be placed on the prognostic value of the IAR. however, the decrease in the IAR is smaller than that of the CAP measured on the same potential in a right/left comparison, so that a decrease in the IAR of over 60% can already herald a poor recovery. Repeated determination of the latency in cases of facial nerve paralysis showed that the mean latency value for the entire group of patients was slightly prolonged at the end of the 1st week, but the latency values obtained in any one particular patient are of no prognostic significance. A comparison between CAP and latency values obtained with the opposite (i.e...

The value of the vascular examination cannot be over-estimated. Symptoms of vascular disease present in the foot and lower extremity may actually be manifestations of severe life-threatening disease. Symptoms, their location, and the frequency and quality of the patient's pain often provide valuable clues for the clinician's diagnosis. Central nervous system symptoms, ocular disturbances, cardiac symptoms, impotence, or constitutional disturbances may all indicate systemic arterial disease. Risk factors for this disease include smoking, hypertension, hyperlipidemia, genetic predisposition, diabetes, emotional stress, and physical inactivity. Those factors attributable to hypercoagulability and venous disease are birth control pill use, estrogen chemotherapy, obesity, prolonged immobilization, paralysis, previous thrombotic episodes, venous stasis disease, and varicose veins. An accurate bilateral assessment of blood pressure, pulses, and capillary perfusion is of critical importance. Careful inspection of the extremity for trophic changes, skin color, texture, temperature, edema, ulceration, atrophy, or paresis, will provide clues of vasculopathy. A relatively accurate assessment of circulatory status may be obtained without the use of exotic instruments. Simple tests such as the elevation and dependency tests, capillary bed return test, venous filling time test, along with blood pressure, pulse, and possibly oscillometry data are valuable in arterial evaluation. Such venous tests as inspection, percussion, Homan's sign, Trendelenburg, and Perthes' tourniquet are useful in the determination of the presence of venous disease. Fortunately, over the past few years tremendous advances have been made in the technology of the vascular laboratory. If symptoms are discovered during the vascular history and physical examination, the complete noninvasive study will provide impressive data to quantitate and specifically establish the diagnosis.

The occurrence of high-risk factors for vascular disorders was analysed in a group of 43 patients suffering from diplopia of unknown aetiology. The subjects (25 men and 18 women) were aged between 17 and 78 years. Previously excluded were patients with intracranial or orbital tumors, ocular myositis or myasthenia, multiple sclerosis, endocrine orbitopathy, head trauma, cerebral hemorrhage or aneurysms, leucaemic infiltrates or metastasising tumors. Compared to the control groups of extensive epidemiological studies, the patients showed a higher prevalence of arterial hypertension and diabetes mellitus. Adipositas, lipometabolic disturbance and cigarette smoking were also more frequent. The findings support the hypothesis of a vascular origin of eye-muscle paresis.

Two cases of a rare peripheral neurological disease (neuralgic amyotrophy of the lower extremity) are presented, with clinical symptoms (severe sciatic pain with motor paresis) that pose differential diagnostic difficulties against a hernia of a lumbar disk. Because of a tendency to heal by itself, the disease has a good prognosis. The diagnosis is based on a process of exclusion of herniated disks, lesions of the lumbar plexus in tumors or after radiation therapy, hematoma of the psoas after coagulation disturbances, birth, or trauma, and nutritive disruptions of the nervous system as in diabetes mellitus. Knowledge of the symptoms of this--in orthopedics--mostly unknown disease and critical interpretation of the clinical and medical-technical data are important to avoid wrong indications for surgery.

Paresis of the oculomotor nerve is a very rare complication of an unruptured arteriosclerotic fusiform aneurysm of the basilar artery. A handful of cases are described in the world literature. A fifty-four-year-old man with a history of hypertension and diabetes mellitus presented with painless partial oculomotor palsy of sudden onset. A cerebral angiogram demonstrated a tortuous fusiform deformity of the basilar artery and the origin of the posterior cerebral arteries, indicative of an arteriosclerotic aneurysmal dilation. A sudden onset of a pupil-sparing ophthalmoplegia is the typical history of a microvascular infarct of the third nerve, whereas pupillary sparing in aneurysmal oculomotor paresis is a very rare event. Special emphasis has been placed on the pupillary size as a guide for the indication of arteriography. The many exceptions to this rule suggest that cerebral arteriography may be indicated more often than generally believed.

In this retrospective study the case reports of 165 patients suffering from an abducens nerve palsy as the main presenting symptom were evaluated. The sixth nerve palsy was more frequent on the left (52%) than on the right hand side (38%), in 10% there was bilateral involvement. In 49 cases a vascular origin was suspected (29.7%), with diabetes mellitus as the most important risk factor (n = 35). Abducens palsies in inflammatory diseases (n = 32, 19.4%) were seen most often in multiple sclerosis (n = 11), viral meningoencephalitis (n = 5) and accompanying systemic viral infections (n = 5). Postvaccinal paresis was seldom (n = 1). Tumours (n = 18, 10.9%) causing sixth nerve paresis were metastases to the brain (n = 7), meningiomas (n = 3) and glioblastomas (n = 2). Nasopharyngeal carcinomas lead in 4 cases to an involvement of the abducens. Aneurysms causing sixth nerve palsy (n = 7, 4.2%) most frequent being located at the intracavernous region of the internal carotid artery (n = 4). In traumatic abducens paresis (n = 5, 3.1%) pathological findings of neuroradiological examinations are rare. In 48 patients (29.1%) diagnosis remained unclear, especially in young adults between the 20th and 40th year of age. Prognosis of abducens paresis is good in lesions of vascular and unknown origin; in these cases non-steroidal antiphlogistics are of benefit.

Conventional electromyography (EMG) and single fiber EMG (SFEMG) were performed in a 64-year-old diabetic woman with mild type B botulism. The main clinical signs were autonomic dysfunction and cranial nerves paresis. Conventional EMG was normal, except for small changes that were consistent with mild mixed peripheral neuropathy in the lower limbs and were related to diabetes. Repetitive stimulation and results of single stimulus before and after full effort were normal. SFEMG showed increased jitter and impulse blocking in clinically normal muscles. The jitter was frequency dependent and improved at a higher innervation rate. Impulse blocking in potentials with only slightly increased jitter was found. The follow-up showed improvement of the jitter in agreement with clinical recovery. Jitter abnormalities were recorded after 16 weeks, when clinical signs of botulism had been reversed to normal. Motor unit fiber density increased progressively, and on examination at 8 weeks, some potentials showed very high jitter values. Both findings might suggest new endplate formation, perhaps due to ultraterminal sprouting development.

Carotid endarterectomy in 39 elderly patients was carried out under local anesthesia and neuroleptic analgesia. There were no deaths within 30 days. Two patients required an intraoperative shunt because of signs of ischemic changes (aphasia, motor changes) during two-minute test cross-clamping. In two patients, transient vocal cord paresis was observed, and seven patients (18%) experienced immediate postoperative hypertension. Our results support the contention that in awake elderly patients the need for an intraoperative shunt can be accurately assessed by simple neurological monitoring. Carotid surgery under local anesthesia and neuroleptic analgesia appears to be a safe procedure, and is especially recommended for elderly patients with hypertension, diabetes mellitus or ischemic heart disease.

In 40 patients with insulin-dependent diabetes mellitus, the number of gastrin cells in the mucous membrane of the antrum of the stomach was measured by immunohistochemistry according to the method of L. Sternberger. The number of the cells depended on the gravity of antral gastritis, namely their number decreased as the lesion was aggravated. The basal level of serum gastrin was determined by radioimmunoassay in 144 patients with insulin-dependent diabetes mellitus. The high basal level of gastrin was recorded in patients with achlorhydria. However, no correlation was established between the gravity of antral gastritis and the basal level of serum gastrin. If the basal gastrin level is too high, the possibility of asymptomatic paresis of the stomach should be taken into account together with the other factors.
