Carbon monoxide (CO) poisoning is the commonest single cause of fatal poisoning in the U.K. (Broome & Pearson, 1988). The clinical features are numerous and include headache, fatigue, dizziness, confusion, memory loss, paraesthesia, chest pain, abdominal pain, nausea, and diarrhoea as well as coma, convulsions and death. Without adequate treatment many patients develop neuropsychiatric sequelae including headaches, irritability, memory loss, confusion and personality changes. The diagnosis of CO poisoning is often suggested only by circumstances surrounding the victim, and remains a challenge to the A&E department. Hyperbaric oxygen therapy (HBO) is internationally accepted as the most powerful form of treatment in severe cases (Drug & Therapeutics Bulletin, 1988; Lowe-Ponsford & Henry, 1989). However, in the U.K. treatment with HBO is often not considered due to lack of hyperbaric facilities (Meredith & Vale, 1988; Anand et al., 1988), and due to inadequate awareness on the part of hospital staff. We report a case of a patient deeply unconscious as a result of CO poisoning, in which serial treatments with HBO over a period of 14 days, produced dramatic results.

When human divers and experimental animals are exposed to high pressure of helium-oxygen mixture, they develop the high pressure neurological syndrome, characterized by nausea, vertigo, tremor, myoclonus, EEG modifications and convulsions. Free-moving rats were stereotaxically implanted in the anterior caudate nucleus with a microdialysis probe to measure dopamine, dihydroxyphenylacetic acid and homovanillic acid levels during different phases of a simulated dive up to 5.1 MPa. Compression was found to cause an increase in extracellular dopamine and dihydroxyphenylacetic acid concentrations, but not in homovanillic acid. This represents a specific effect of high pressure on the dopaminergic pathway. Recent findings on D2 autoreceptors, showing a decrease in receptor affinity under pressure, allow us to conclude that pressure increases dopamine synthesis through a direct action on D2 autoreceptors.

A case of agenesis of the internal carotid artery combined with arachnoid cyst is reported. This 11-year-old boy had occasionally complained headache and nausea since he was of 9 years old. He was admitted to our hospital because of an epileptic seizure. Physical and neurological examinations on admission were normal. A CT scan showed a cystic mass in retrocerebellar region. MRI suggested absence of flow void area indicating internal carotid artery in the cavernous sinus on left side. Left common carotid angiogram showed absence of the internal carotid artery. Bilateral A2 segments were supplied by right A1 with tortuous anterior communicating artery. Left middle cerebral artery and left ophthalmic artery were supplied via dilated left posterior communicating artery on left vertebral angiogram. Thin slice, axial target image of the CT revealed absence of the left bony carotid canal. MRI by 3D TOF method confirmed no blood flow in this area. MR angiography provided sufficient information about cervical vessels non-invasively. 123I-IMP SPECT image ascertained no hypoperfusion area in left cerebral hemisphere. Convulsion was controlled with sodium valproate. Association of agenesis of the internal carotid artery and arachnoid cyst could be a coincidence.

The authors specified, briefly, the different subgroups and prevalence of the molecules from the quinolone family: Nalidixic acid (synthesised in 1958), the quinolones of second generation (oxilinic acid, piromidique, pipemidique and flumequine) and the quinolones of third generation (ciprofloxacine, norfloxacine, ofloxacine, perfloxacine). After having mentioned the extent and the importance of using these antibiotics in infections, they stressed the fact that the quinolones are antibiotics which are largely prescribed in clinics and hospitals. The authors reported afterwards the observation of a young female, without any precedent neuropsychiatric disorders having shown a complex clinical state with neurological and psychiatric disturbances during the first day of treatment for a urinary infection with 4 tablets of flumequine 400 mg per day (instead of 3 recommended). Mrs. A. 25 years of age was seen to during the night at The "Consultation Psychiatrique d'Orientation et d'Accueil" (C.P.O.A.). of Sainte-Anne hospital by the resident psychiatric of a General Hospital "after behavioural disturbances". In fact, about 3 hours before and 15 minutes after the third dose of flumequine (2 tablets of 400 mg), this makes the total dose taken over 12 hours is equal to 400 x 4 = 1,600 mg, the patient developed an intense discomfort with blurred vision accompanied by nausea, followed by a state of restlessness and incomprehensible speech. A testimony by relatives revealed that she suffered, shortly afterwards, a generalised fit which affected her 4 limbs with a fixation of her eyes and hypersalivation and convulsions without either swallowing the tongue or involuntary urination.(ABSTRACT TRUNCATED AT 250 WORDS)

An outbreak of severe haemorrhagic illness began in the municipality of Guanarito, Portuguesa State, Venezuela, in September, 1989. Subsequent detailed study of 15 cases confirmed the presence of a new viral disease, designated Venezuelan haemorrhagic fever. Characteristic features are fever, toxicity, headache, arthralgia, diarrhoea, conjunctivitis, pharyngitis, leucopenia, thrombocytopenia, and haemorrhagic manifestations. Other features include facial oedema, cervical lymphadenopathy, nausea/vomiting, cough, chest or abdominal pain, and convulsions. The patients ranged in age from 6 to 54 years; all were residents of rural areas in central Venezuela, and 9 died. Infection with Guanarito virus, a newly recognised arenavirus, was shown by direct culture or by serological confirmation in all cases. Epidemiological studies suggest that the disease is endemic in some rural areas of central Venezuela and that it is rodent-borne. Venezuelan haemorrhagic fever has many similarities to Lassa fever and to the arenavirus haemorrhagic fevers that occur in Argentina and Bolivia.

Photosensitivity has proved to be a useful model to study the acute effects of experimental antiepileptic drugs (AEDs). The photosensitivity range is usually diminished or even abolished after administration of a known or experimental AED. An increase in photosensitivity, an unexpected reaction, was found in four photosensitive epileptic patients after oral ingestion of 500, 100, or 50 mg of Org 6370. Moreover, the three patients receiving doses of 100 and 500 mg reported nausea, dizziness, restlessness, and an increase in spontaneous epileptic seizures (myoclonus and in one patient a generalized tonic-clonic convulsion). The side effects coincided with peak Org 6370 serum levels. Our findings indicate that in the photosensitivity model experimental drugs with proven anticonvulsant properties in animals may increase rather than decrease the degree of patient photosensitivity. Photosensitive patients may represent a special subgroup of epileptic patients and therefore need to be classified as such.

Twenty five idiopathic epileptic children with occipital electroencephalographic (EEG) foci have been studied for more than 3 years clinically as well as electroencephalographically. They were categorized into two groups, i.e., those with (A group) and without (B group) visual symptoms. Not only visual symptoms, but also headache, nausea, vomiting or generalized tonic clonic convulsion (GTC) were observed in group A. GTC or tonic deviation of the eyes were observed in group B. Migrainous symptoms were present in 3 cases of group A. Interictal EEGs consisted of spikes or spike and wave complexes in the occipital area. In some cases epileptic foci existed not only in the occipital area, but also in other regions. The mean age of the onset of the clinical symptoms was 8 in group A and 5 in group B. Beyond the age of 15, the abnormal EEGs were observed in 80% of the cases in group A, and in 18% of the cases in group B. The symptoms disappeared by 9 years of age in 92% of the cases in group B, and by 15 years of age in 82% of the cases in group A. From these results the prognosis of idiopathic epilepsy of childhood with occipital EEG foci was considered as good.

Sixteen patients acutely poisoned with aldrin were examined to evaluate a possible correlation between serum aldrin and dieldrin levels and clinical complaints. The patients were classified as having mild (N = 8), moderate (N = 5) or severe (N = 3) poisoning according to clinical symptoms. Concentrations of less than 20 micrograms/l were usually associated with mild poisoning, which involved complaints such as nausea, vomiting and epigastric pain, whereas concentrations of 100 to 200 micrograms/l were considered to represent moderate intoxication and were associated with nausea, vomiting, epigastric pain, headache, dizziness, and convulsions. Severe or fatal cases were associated with levels above 700 micrograms/l. Taken together, these results suggest that serum aldrin and dieldrin levels can be used as indicators of clinical prognosis after acute poisoning with these insecticides and that convulsions could suddenly occur even in the absence of prodromal signs or symptoms.

In 52 patients 0.5-3.0 ml of iohexol, 180 mg/ml, was injected using lateral injection technique and fluoroscopy control. A total of 146 lumbar discs using local anaesthesia was injected. Two types of premedication were used; either diazepam alone or diazepam in combination with pethidine and glycopyrronium bromide. There was no difference in the discography injection pain between the groups (X2 = 0.774, P greater than 0.05]. During discography, some patients had nausea (2%), convulsions (4%), back pain (6%) and hypotension (10%), but no allergic reactions were seen. This suggests that these immediate reactions are more related to the procedure itself than to the non-ionic ratio 3.0 iohexol contrast medium. More troublesome iatrogenic complications were seen the day after the discography in the form of severe headache (10%) probably related to liquor leakage, and increasing low back pain (81%). The latter may be caused by local haematoma or chemical irritation from iohexol. Patients with no pain during injection had a relatively slight need for analgesics (Somer's D = -0.196, P less than 0.05).

Groups of 64 male and 64 female Wistar rats were given thiram at constant dietary doses of 0, 3, 30, and 300 ppm (0, 0.1, 1.2, and 11.6 mg/kg/day for males and 0, 0.1, 1.4, and 13.8 mg/kg/day for females) for 104 weeks. Eight males and eight females in each group were killed after Weeks 13, 26, and 52. For the dog study, four male and four female beagle dogs were alloted to each group and treated with the compound at 0, 0.4, 4, and 40 mg/kg/day for 104 weeks. The dogs in the 40 mg/kg/day group had severe toxic signs, including nausea or vomiting, salivation, and occasional clonic convulsion, and all were subjected to unscheduled necropsy before Day 203 of treatment. The dogs also had ophthalmological changes such as fundal hemorrhage, miosis, and desquamation of the retina which were consistent with the retinal lesions shown by histopathology. The rats of the high-dose group had retarded growth with a slightly decreased food intake. Anemia was evident in high-dose female rats and in middle- and high-dose dogs. Liver failure in male and female dogs and kidney damage in female dogs were detected in middle- and high-dose groups by blood biochemistry and/or histopathology. Regressive changes of the sciatic nerve accompanied by atrophy of the calf muscle were seen in female rats of the high-dose group but not in male rats. In high-dose rats, progression of myocardial lesions of the heart and chronic nephrosis of the kidney were depressed in males and females, respectively. Female rats of the middle- and high-dose groups had decreased occurrences of mammary fibroadenoma and decreased development of skin masses.
