The clinical features of 19 patients with neurological manifestations unexplained by another disease and positive serology for Borrelia burgdorferi were studied. ECM was present in only 11% of the cases and 32% referred tick bite. The characteristic features for suspicion of NB according to our series was the presence of polyneuritis in 84% of the cases specially in the form of multiple mononeuritis and involvement of the facial nerve (79%) leading to even greater suspicion with the association of V pair involvement. Seizures, sleep disorders, and higher mental dysfunction may be found in association with other more characteristic neurological features. The typical triad of NB (aseptic meningitis, facial paralysis and polyradiculoneuritis) was found in 21% of the patients and in the absence of another disease to justify the same neuroborreliosis (NB) seemed evident. In all the cases components of this triad were found. Headache, arthralgia, fever and, less frequently, arthritis are other symptoms often past with the presence of anti-BB antibodies. Patients with the shortest evolution most frequently presented antecedents of facial paralysis, sensory alterations and Romberg's sign than patients of longer evolution. CSF demonstrated the presence of pleocytosis in 24% of the cases and in only one patient a slight increase in the intrathecal activity of IgG was observed which may be of use in differential diagnosis with MS. MR showed alterations in 61% of the patients and, while not specific, the lesions present subcortical predominance.

Fibromuscular dysplasia (FMD) is a non-atheromatous, non-inflammatory, segmental arteriopathy of unknown etiology. Fibroplasia of the tunica media is most common. After the renal arteries, the carotid arteries are most frequently affected. Angiographically beaded and tubular stenoses are seen. Complete occlusions and spontaneous dissection of the carotid arteries occur. The angiopathy causes general symptoms such as headache and vertigo, but also recurrent TIA and ischemic cerebral infarction. We examined 15 patients (12 female) suffering from FMD and stroke. The diagnosis of FMD was based on angiographic findings in all cases. 13 patients made a good recovery and seven of them could be discharged from hospital without any neurological deficit. Apart from conservative treatment, primary percutaneous or operative angioplasty may be necessary in some cases in spite of the mostly benign outcome of the disease. Acetylsalicylic acid should be given in all cases.

Continuous epidural anesthesia (CEA) is generally accepted as a routine method of regional anesthesia while there has been only limited application of continuous spinal anesthesia (CSA), due mainly to a lack of adequate spinal catheters. With the introduction of a new, ultra-thin spinal catheter (32 G) inserted via a thin puncture needle, some of the complications reported after CSA can be eliminated. We studied CSA versus CEA in lower-extremity operations. METHODS. We evaluated 33 patients in a prospective, randomized study. All were comparable with respect to age, anesthetic risk (ASA II-III), and pre-existing diseases. The only exclusion criterium was the presence of a coagulation disturbance. The CSA group consisted of 17 patients (mean age 75.5 +/- 0.1 year); 26 G puncture needle and 32 G catheter were used. The CEA group consisted of 16 patients (mean age 73.8 +/- 11.0 years); an 18 G puncture needle and 22 G epidural catheter with a stylet were inserted with the loss-of-resistance technique. Both catheters were placed with the patient in a sitting position and left in place for 24 h in order to administer local anesthetics (LA) for postoperative analgesia as required. Hemodynamic parameters-mean arterial pressure (MAP) and heart rate (HR)-were compared in each group at 5-min intervals for 30 min after administration of local anesthetic and at 10-min intervals during the operation. Additionally, the ECG, pulse oximetry, respiratory rate, diuresis, and blood gases were monitored. After placement of the catheter, patients in the CSA group received 1.9 ml (+/- 0.2) bupivacaine HCl 0.5%. Patients in the CEA group received 12.6 ml (+/- 2.5) bupivacaine HCl 0.5%. For statistical evaluation of the data we used mean values, standard deviation (+/-), the Kruscal-Wallis procedure, and Student's t-test for unpaired data. P less than 0.05 was considered significant. RESULTS. The mAPs in the CSA group generally remained lower than those of the CEA group. However, over the course of the operation as well as after repeated injections, the difference between the two groups decreased. Only at 5 min after administration of the initial dose was a statistically significant difference in blood pressures between the two groups observed. A clinically relevant, rapid decrease in blood pressure due to relatively high doses of LA was seen in 1 case in each group. The first reinjection of LA after the initial dose was after 1.9 h in the CSA group (bupivacaine HCl 0.5% 1 +/- 0.3 ml) and after 1.8 h in the CEA group (bupivacaine HCl 0.5% 4.5 +/- 1 ml). The total dose of bupivacaine in the CSA group was 0.18 ml/kg per hour versus 0.8 ml/kg in the CEA group. No post-dural puncture headache was observed in the CSA group. DISCUSSION. The catheter designed for CSA is easy to use, although because of its small diameter a certain manual dexterity is required. In addition, CSA resulted in a more rapid onset of action and more pronounced sensorimotor blockade than did CEA. Hemodynamic alterations and side effects were comparably low in both groups.

ASA Grade I and II patients admitted for day-case urological surgery received no premedication or an oral dose of temazepam 10 mg. Anaesthesia was induced with methohexitone and maintained with nitrous oxide, oxygen and halothane or enflurane via a Mapleson A circuit. The incidence of post-operative headache was investigated by an independent observer. Eighty patients were studied (50 male and 30 female) of whom 32 (40%) had post-operative headaches. Post-operative headache was significantly correlated with female sex and frequent 'normal' headache occurrence. The lack of previous surgical experience was a significant risk factor and a loose insignificant association existed with age, the use of halothane and the presence of pre-operative headache. Temazepam premedication had no effect and was associated with significantly more patients complaining of feeling cold.

Substance abuse has been reported frequently in chronic headache patients. The problem exists in most Western countries. Abuse of various compounds frequently leads to a state of dependency. Prescription as well as over-the-counter agents are often abused. Aspirin, acetaminophen, and caffeine are the most frequently abused compounds. Butalbital, ergot alkaloids, NSAIDS, and narcotic and oral or intranasal sympathomimetics are often abused. Patients with chronic daily headache complain of symptoms that may suggest a mixed-type headache. Features of migraine and muscle contraction headache often coexist in these individuals. It has been suggested that the most frequent cause for the transformation of a periodic headache into a daily headache is substance abuse. Substance abuse and drug dependency have multiple causes, and the etiology will reside with the compounds that are used to excess. The problem may arise as a result of poor instructions from the physician, improper diagnosis with gradual escalation in amounts of drug consumed, or a reinforcement mechanism and a brain stimulation-reward effect. The brain reward system has been studied with narcotics and psychomotor stimulants. It may be activated to a lesser degree with ergotamine, barbiturates, and other abused substances. The long-term effects of substance abuse are contingent on the compounds that are used. They may result in organ damage, medical complications, vascular injury, and a refractory state with chronic headache that eludes successful management of the headache disorder. Patients exhibit a less-than-satisfactory quality of life and are often depressed. Treatment includes outpatient care in cooperative, less dependent patients. Often patients will require inpatient management in order to discontinue use of the abused agents. Pharmacologic agents, behavior modification, psychotherapy, dietary intervention, and acupuncture may be necessary to treat the patient. Each patient must be treated by an interested physician, and the patient will require one or more of the preceding measures for a successful outcome. Often abused compounds must be discontinued in order to obtain a satisfactory response in an individual with chronic headache.

Essential thrombocythemia (ET) is a rare disorder in children. An 11-year-old white boy was first seen in January 1986 with symptoms of abdominal pain. His platelet count was 1.5 million/mm3. Other hematological values and coagulation studies, including bleeding time, were normal. There was laboratory evidence of mild platelet dysfunction. Using the criteria of the Polycythemia Vera Study Group, a diagnosis of ET was made. He developed frequent headaches. Aspirin was prescribed for the next 2 years at varying doses and frequency. During the period, platelet counts ranged between 1 and 3 million/mm3. In view of progressive headaches and evidence of increasing platelet dysfunction, further treatment was indicated. The use of a new agent, anagrelide, reported effective in adults with ET, resulted in amelioration of symptoms and improvement in quantitative and qualitative platelet control with no significant untoward effects.

Continuous spinal anesthesia (CSA) fell into disuse because of a presumed high incidence of post dural puncture headache (PDPH). A careful retrospective study of 226 continuous spinal anesthetics administered for a variety of surgical (not obstetric) procedures was carried out and indicated that none of the patients developed PDPH. While 62% of the patients were older than 60 years of age, a group with a low incidence of PDPH, it was expected that some of the younger patients would develop this complication, especially since 94% of the dural punctures were carried out with 17- and 18-gauge needles. This study also revealed only a 12% incidence of hypotension, an impressive finding because 64% of the patients were considered ASA III or IV. There were no other intraoperative or postoperative complications or deaths due to CSA. This retrospective study indicates that CSA, properly carried out with 17- and 18-gauge needles, is not necessarily associated with a high incidence of PDPH; and in view of its low morbidity and mortality, CSA is particularly useful and safe in the poor-risk elderly patient. This study also raises the question as to whether there is a need for the recently developed (and expensive) microcatheters that fit through very small-bore needles.

Two hundred and sixty-four patients were included in an open, randomized, multicenter trial, with the aim of determining whether nicardipine can be useful in the prevention of cerebral infarction. The patients had experienced one or more transient ischemic attacks, reversible ischemic neurologic defect, or stroke with minor permanent neurological deficit in the 12 months before enrolling in the study. Each patient was randomly assigned to received 250 mg of aspirin once daily plus 20 mg of nicardipine thrice daily (n = 170) or 250 mg of aspirin once daily (n = 94) for 12 months. During the 12-month treatment period, 12% of the aspirin-plus-nicardipine group and 19% of the aspirin-only group experienced an ischemic cerebrovascular event; at six months, the cumulative incidence of events was significantly lower in the aspirin-plus-nicardipine group than in the aspirin-only group. One patient in each group died of a recurrent stroke. Aspirin-related side effects were dyspepsia (reported by four patients), heartburn (by seven), nausea and vomiting (by four), and melena (by five); nicardipine-related side effects were transient hypotension (by two), headache (by four), ankle edema (by three), and constipation (by four). Results indicate that the addition of nicardipine to antiplatelet treatment may safely prevent the recurrence of ischemic cerebrovascular events.

In a double blind cross-over study, 28 patients, 5 male and 23 female, aged 31 +/- 14 years, after a run-in period of 8 weeks, were treated for 3 months with acetylsalicylic acid and for another 3 months with metoprolol, both in a prophylactic mode. Attack frequency was reduced significantly with both therapeutic regimens (ASA p less than 0.001, metoprolol p less than 0.00005). Reduction of attacks below 50% was seen with metoprolol in 14 cases, and with ASA in three cases. Even though ASA was of statistically significant efficacy in migraine prophylaxis, it clearly is not the drug of first choice in migraine prophylaxis.

A case is reported of an acute intracranial subdural haematoma following an accidental dural puncture during an epidural anaesthesia. A seventy-year old man, class ASA I, was operated on for prostatic adenoma under epidural anaesthesia. Dural puncture occurred during the first introduction of the needle into the L4-L5 epidural space. Epidural anaesthesia was nevertheless obtained by introducing the catheter at the L3-L4 level. The immediate peroperative and postoperative course was uneventful, apart from persisting headache. After removing the epidural catheter at 24 h postoperatively, the patient received calcium heparinate. 26 h later, he complained of worsening headache and became rapidly deeply comatose. The computer tomographic scan showed air in the ventricles and a large right-sided subdural haematoma which was immediately discharged. Although the link between subdural haematoma and dural puncture is well known, the acuteness and rapidly fatal evolution of this case were exceptional and may have been facilitated by the big size of the needle, dehydration and hypercoagulability.
