Anterior communicating artery aneurysm was shown in a 48-year-old man who had suffered from subarachnoid hemorrhage (SAH) by cerebral angiography. Right pterional approach was performed on the 40th day after SAH. Premature ruptured occurred during aneurysmal manipulation and temporary clip (Scoville clip) was placed at the middle of the right A1 segment for fifteen minutes. the anterior communicating artery aneurysm was successfully clipped and postoperative course was uneventful. But, four days after the operation, the patient fell into coma following generalized tonic convulsion. Lumbar puncture showed fresh SAH. Consciousness recovered gradually to a lethargic state. A newly formed berry aneurysm was revealed on the righ A1 segment at the site of the temporary clip application by cerebral angiography performed on the seventh day after aneurysmal surgery. Second attack occurred on the 12th postoperative day and the patient died on the 16th day after the operation. Postmortem findings disclosed massive subarachnoid and intraventricular hemorrhage from the ruptured aneurysm at the right A1 segment. Microscopic examination of the aneurysm and the right A1 segment. microscopic examination of the aneurysm and the right A1 segment showed the extensive destruction of the artery and massive proliferation of aspergillus in the arterial wall which was prominent of its outer layer. The mechanism of the formation of the new aneurysm in this case was considered as follows: the arterial wall was primarily damaged by the temporary clip and was weakened rapidly by the invasion of aspergillus, probably producing thrombosis of the vast vasorum, hemorrhage, and necrosis in it.

Patients with agammaglobulinemia are particularly susceptible to chronic enteroviral infections of the central nervous system. Data on 42 patients were obtained by literature review, communications with other physicians, and personal experiences. Thirty-eight patients had congenital immunodeficiencies, most frequently X-linked agammaglobulinemia. Most patients who could be assessed were receiving maintenance therapy with intramuscular gamma-globulin before their enteroviral infection. Seven patients had not been recognized as hypogammaglobulinemic before the onset of infection. The commonest pathogens were echoviruses (37 of 41 cases), especially type 11 (11 cases). Thus far, four patients have had sequential or simultaneous infections with a second enteroviral serotype. Other features of the disease have included weakness, lethargy or coma, headaches, hearing loss, seizures, ataxia, and paresthesias. Some patients have also had nonneurologic manifestations of chronic enteroviral infection, including fever, the dermatomyositis-like syndrome, edema, rashes, and hepatitis. Treatment has consisted primarily of antibody administration, either in intravenous immunoglobulin preparations or in immune plasma. Twelve patients have received intraventricular immunoglobulin through reservoir devices; six of these 12 have improved substantially, as judged by clinical criteria.

A total of 208 patients underwent brain biopsy for presumptive herpes simplex encephalitis and were randomized to receive either vidarabine, vira-A, at 15 mg/kg/day, or acyclovir, at 30 mg/kg/day for ten days. 69 patients (33%) had biopsy-proven disease; 37 received vira-A and 32 acyclovir. With the exception of age, patient populations were balanced for demographic characteristics. Overall survival for acyclovir recipients was 72% compared with 46% for vira-A-treated patients 18 months after therapy (p = 0.008). After adjustment for differences of age between treatment populations by multivariant regression analyses, acyclovir treatment remained superior to vidarabine therapy (p = 0.041). Mortality varied according to the level of consciousness at the onset of therapy. For lethargic, semicomatose and comatose patients, mortality was 42%, 46%, and 67%, respectively, for the vira-A-treated patients and 0%, 25% and 25%, respectively, for acyclovir-treated patients. Six months post-therapy morbidity assessments revealed five (14%) vira-A versus 12 (38%) acyclovir recipients who had returned to normal function, while eight (22%) and three (9%), respectively, had moderate debility. Outcome differences were significant (p = 0.02; Wilcoxon, 2-sample test) using an adapted scoring system. Age and Glasgow coma scale greater than 10 predicted the best outcome following acyclovir treatment. Disoriented patients who flex and respond by eye to pain had no mortality and 50% returned to normal. These data indicate that acyclovir is the treatment of choice for biopsy-proven herpes simplex encephalitis.

Forty-one infants with neonatal seizures frequent enough to be captured by randomly recorded routine EEG examinations were studied to determine how often their electrographic seizures were occult (subclinical) and to examine the effects of seizure duration and mental status on their clinical visibility. Seizures were the result of diverse etiologies and most infants had received one or more antiepileptic drug prior to the EEG recordings. The majority of electrographic seizures were occult: only 84 of 393 (21%) were accompanied by distinctive clinical seizure activity; the remaining 79% were occult. There was no significant difference between the duration of EEG seizures with distinctive clinical signs and those without. There was no significant difference in the proportion of occult seizures in neonates with preserved consciousness compared with lethargic or comatose infants. We conclude that unaided visual inspection of infants seriously underestimates true seizure frequency. Long-term EEG monitoring may be necessary in many infants to determine their real seizure frequency and to judge the adequacy of antiepileptic drug treatment.

A case of multiple spontaneous intracerebral hematomas is presented. A 67-year-old man with 7 years history of hypertension had sudden clumsiness in his right hand and an hour later dysarthria appeared. A CT scan taken 3 hours after the onset revealed two well demarcated high density areas in the left putamen and in the parietal subcortex. A diagnosis of multiple intracerebral hematomas was made. On neurological examination he was midly stuporous (13 points of Glasgow Coma Scale). Dysarthria, right hemiparesis and right extensor plantar response were seen. CT scan of 6 hours later disclosed the same findings as the previous study. He recovered well and neurologically free in a few days. On the following CT scans both hematomas were isodense 2 weeks later, and ring-like enhancement effect was noted. CT scan showed normal appearance 7 weeks later. On MRI using 0.5 T unit t-1 and t-2 weighted spin echo images of these hematomas also showed the similar chronological changes. The history, these CT and MRI studies suggest that two hematomas of this case occurred almost simultaneously in one cerebral hemisphere. No causative factors such as blood dyscrasias, AVM, angioma, septicemia, malignancies or sinus thrombosis was identified. We consider that a hypertensive intracerebral hematoma of the putamen was followed by the parietal intracerebral hematoma within a few hours, although amyloid angiopathy was not completely excluded because no cerebral biopsy of the lesion was performed.

In a consecutive series of 100 neck explorations for primary hyperparathyroidism, 42 patients were 60 years of age or older; in this group of elderly patients the surgical cure rate was 100%. These patients were reviewed retrospectively by means of a structure interview. Twenty-one patients had had preoperative neuromuscular symptoms that ranged from coma to subjective muscular weakness. These patients had significantly-higher preoperative serum calcium and parathyroid hormone levels than did 21 patients without neuromuscular symptoms (P = 0.003 and P = 0.046, respectively). Most of the neuromuscular symptoms improved in the postoperative period. In particular, 15 of 17 patients with muscle weakness reported a significant improvement, while 14 of 15 patients who suffered from fatigue and lethargy reported an improvement. An improvement also occurred in the level of day-to-day function in eight patients. While surgery for primary hyperparathyroidism generally is undertaken for a specific indication, such as severe hypercalcaemia or renal stones, it appears from this study that neuromuscular symptoms also may improve, particularly in elderly patients.

The International Cooperative Study on the Timing of Aneurysm Surgery included 68 participating centers from 16 different countries. Eight Italian neurosurgical units participated in the Study: Bellaria Hospital, Bologna; Neurological Institute of Milan, Milan; University Hospital, Brescia; University of Milan, Milan; University of Padova, Padova; University of Rome, Rome; Civil Hospital, Verona; and Civil Hospital, Vicenza. The overall case contribution from the Italian centers was 485 cases, 14.1% of the total study population. As compared to the other centers included in the Study, the Italian centers exhibited a higher percentage of patients with impaired consciousness; a later interval of planned surgery from SAH; frequent use of preoperative lumbar drainage, as well as antihypertensives, anticonvulsants, antifibrinolytics, steroids, diuretics and LMW dextran; and less frequent use of sedatives and narcotics. The individual Italian centers differed significantly in regard to patient characteristics and preoperative therapeutic modalities. There was a relatively high number of stuporous or comatose patients admitted to Centers 1, 7 and 8, very few admitted to Centers 5 and 6, and none admitted to Center 2. The different distribution of key prognostic factors prevents a direct comparison of the overall management results of the centers. A stratification of the patients according to a risk scale and/or a prognostic model is required for comparison of the management results.

The 8 Italian centers participating in the International Cooperative Study on Timing of Aneurysm Surgery operated upon 68% of their patients eligible for the study. This low operative rate is mainly explained by the prevailing use of a delayed surgical policy. Only 28% of cases were operated on within 3 days of hemorrhage. Although early surgery was applied in more than 50% of patients from Centers 2, 6 and 7, most other centers operated on approximately 10% of patients within this time interval. Italian centers exhibited a wide variation in planned and actual surgery interval, with only 48% of their patients eventually operated on at the planned time. Differences from planned and actual timing of surgery were less consistent in the units performing early surgery. Preoperative conditions were different between the individual centers. The percent of patients alert at the time of surgery varied from approximately 50% in Centers 3 and 7 to 90% in Center 5. Centers 2 and 6 never operated on comatose patients and rarely stuporous patients. During surgery, induced hypotension was used in 67% of Italian patients. The brain was tight at exposure in 42% of patients from Italian centers; the difference from the other study centers was very significant (p = 0.0009). Consequently major brain resection was more frequently performed in Italy than in the other centers. Brain conditions depended mainly upon timing of surgery and preoperative grade (except for comatose patients) and varied accordingly between the individual centers. Temporary arterial occlusion was rarely used in Italian centers. Intraoperative bleeding from the aneurysm was slightly more frequent than in the other centers. The overall incidence of intraoperative complications was unremarkable. There were significant differences between the Italian and the other centers regarding the use of postoperative routines and medications. In Italian centers ventricular CSF drainage, shunt insertion, ICP monitoring, sedatives and analgesics were less frequently used; lumbar CSF drainage, anticonvulsants, steroids, and diuretics were applied more frequently. In the individual centers the major differences were in the use of antihypertensives, vasopressor agents, diuretics, hypervolemia, and low-molecular weight dextran.

Acute lithium toxicity generally presents with a change in mental status, usually seen as lethargy progressing to coma as poisoning becomes more severe. We discuss three patients who presented with mild lithium toxicity. In two patients the presentation mimicked mania, but the third presented with a more typical toxic confusion state. Improvement in all cases paralleled the drop in serum lithium levels. This uncommon presentation of lithium toxicity is not adequately stressed in the literature.

Despite the widespread use of non-steroidal anti-inflammatory drugs (NSAIDs), the current number of reported cases of poisoning is small. However, with the introduction of 'over-the-counter' preparations of NSAIDs in some countries (e.g. ibuprofen in the UK and USA) an increased incidence of acute poisoning from this group of drugs can be expected. Conventionally, NSAIDs are divided into the following groups based on their chemical structure: arylpropionic acids, indole and indene acetic acids, heteroarylacetic acids, fenamates, phenylacetic acids, pyrazolones and oxicams. Unless NSAIDs are ingested in substantial overdose, acute poisoning with these agents does not usually result in significant morbidity or mortality. In most cases the clinical features are mild and confined to the gastrointestinal and central nervous systems, though acute renal failure, hepatic dysfunction, respiratory depression, coma, convulsions, cardiovascular collapse and cardiac arrest may complicate severe poisoning. Arylpropionic acid derivatives were thought initially to have a low order of toxicity in overdose but, in addition to anticipated gastrointestinal symptoms, headache, tinnitus, hyperventilation, sinus tachycardia, hypoprothrombinaemia, haematuria, proteinuria and acute renal failure have been described. In addition, drowsiness, coma, nystagmus, diplopia, hypothermia, hypotension, respiratory depression and cardiac arrest have been reported in severe cases of poisoning. Oxyphenbutazone and phenylbutazone are considerably more toxic in overdose. Complications of severe poisoning include coma, convulsions, hepatic dysfunction, acute renal failure, sodium and water retention, haematuria, cardiovascular collapse, respiratory alkalosis, metabolic acidosis, hypoprothrombinaemia and thrombocytopenia. In contrast, indomethacin appears to be much less toxic. In addition to gastrointestinal symptoms, indomethacin taken in overdose induces headache, tinnitus, dizziness, lethargy, drowsiness, confusion, disorientation and restlessness. Only 1 case of acute sulindac poisoning has been reported in the literature. A 16-year-old boy was admitted with hypokalaemia (2.2 mmol/L), transient granulocytosis and 'scanty' haematemesis after ingesting 12 g sulindac. No case of acute tolmetin poisoning have been reported. The fenamates (flufenamic acid, meclofenamic acid, mefenamic acid, tolfenamic acid) are, with the exception of mefenamic acid, not as widely prescribed as other groups of NSAIDs. In overdose, mefenamic acid may result in nausea, vomiting, diarrhoea, muscle twitching, convulsions and coma.(ABSTRACT TRUNCATED AT 400 WORDS)
