Acquired Immune Deficiency Syndrome (AIDS) has been spreading in Africa and other continents of the world. While there is a dearth of information on AIDS-related neuro-psychiatric disorders in the African population, data from Europe and America indicate that patients with AIDS experience a lot of psycho-social difficulties and suffer from a variety of psychiatric syndromes such as anxiety state, depression, manic illness and schizophreniform disorder. Neurological sequelae of AIDS include acute and sub-acute encephalitis, meningitis, myelopathy, chorioretinitis and peripheral neuropathy. These changes may occur from direct neuropathic effects of human immuno-deficiency virus (HIV) or secondary to opportunistic infections and neoplasms involving the central nervous system. It is suggested that psychiatrists need to be fully involved at all levels of clinical care, education and research on AIDS. Attention should be focussed on the neuro-psychiatric consequences of AIDS in the African population to allow for cross-cultural comparison. In addition, the need to incorporate information and education programmes on AIDS into the primary health care programmes of developing countries is emphasised.

An epidemiological community-based study of incident cases with non-provoked epileptic seizures, using case-referent methodology, was carried out to explore possible risk factors for epileptic seizures. 83 cases, between 17 and 74 years of age, of whom 67.4% had seizures of localized onset, were compared with 2 age- and sex-matched referents. Higher birth weight, movement disabilities, mental retardation, head trauma, brain tumor, depression, a period of unemployment during the previous 6 months and a history of epilepsy in relatives were more common in cases than in referent subjects. No difference was found in the socioeconomic factors investigated, except that the cases belonged to smaller households. Prematurity, home or hospital birth, parents' age at birth of cases or referents, febrile convulsions in relatives, various infections including meningitis and encephalitis, cerebrovascular disease, and alcohol, tobacco, sleep and nutritional habits were not found to be associated with development of seizures. The recent life events investigated, at home or at work, occurred as often in cases as in referents, except that significantly fewer cases had received any increase in salary during the last 6 months. The relationship between depression and development of seizures should be explored further. Moreover, the possibility of false negative results should be considered because of the sample size.

In the past, pain control for chronic pain syndromes using narcotic infusion has been carried out primarily via the intrathecal (subarachnoid) route. This report presents one of the first large series of terminally ill cancer patients with intractable pain treated with continuous epidural morphine infusions by means of implanted pumps and epidural spinal catheters. The purpose of the study was to demonstrate that the epidural route is effective with minimal complications, and that screening with temporary epidural catheter infusions results in a high rate of subsequent pain relief. A multidisciplinary team (neurosurgeon, anesthesiologists, psychiatrists, oncologists, and nurse clinicians) evaluated and treated all of the patients studied. Percutaneous placement of temporary epidural catheters for a trial assessment was performed by the anesthesiologists. Pain evaluations were conducted independently by psychiatrists using both verbal and visual analog scales. From 1982 to 1988, 41 (59.4%) of 69 patients evaluated for eligibility experienced good pain control during trial assessment and were subsequently implanted with Infusaid infusion pumps. Preinfusion pain analog values were 8.6 +/- 0.3 and postimplantation values at 1 month were 3.8 +/- 0.4 (p less than 0.001). Over this same 1-month period. requirements of systemic morphine equivalents decreased by 79.3% with epidural infusions as compared to preinfusion requirements (p less than 0.001). There were no instances of epidural scarring, respiratory depression, epidural infections, meningitis, or catheter blockage. One patient developed apparent drug tolerance and three patients required further catheter manipulations. This series strongly suggests that significant reductions in cancer pain can be obtained with few complications and a low morphine tolerance rate using chronic epidural morphine infusion. Anesthesiology and psychiatry input, along with temporary catheter infusion screening and quantitative pain evaluations using analog scales, are essential.

Portosystemic shunt was diagnosed in a 6-month-old Quarter Horse filly with acute onset of apparent blindness and a 3-month history of depression, lethargy, and ataxia. Clinicopathologic test results indicated slightly high gamma-glutamyl transpeptidase activity and serum total bilirubin concentration. Sulfobromophthalein half time was prolonged, and plasma ammonia and serum bile acid concentrations were high as well. Histopathologic findings of percutaneous liver biopsy included widespread hepatocyte atrophy and numerous prominent small arterioles in the area of the portal triad. On the basis of history, clinical findings, and clinicopathologic abnormalities, a presumptive diagnosis of portosystemic vascular anomaly was made. To confirm the tentative diagnosis, nuclear hepatic scintigraphy and operative mesenteric portography were performed. Medical treatment was unsuccessful, and the foal was euthanatized. Portosystemic shunts have been described in dogs and cats, but few cases have been reported in large animal species. Other, more common causes of neurologic abnormalities in foals, such as trauma, vertebral body abscesses, brain abscesses, and meningitis, must be ruled out before portosystemic shunt is considered.

Long-term use of spinal opioids to treat chronic severe pain is widely established. However, the indications, shortcomings and complications of the method have not been completely described. Experience with spinal opioids was analysed for the period 1979-1984 in a nationwide Swedish survey. Out of 93 anaesthesia departments, 69 used the method. Approximately 750 patients were treated with epidural morphine for an average duration of 124 days (3-450). Eighteen patients were treated with intrathecal morphine for an average period for 47 days (3-90). The intrathecal approach was used in all clinics because of failure of the epidural route. In only one department was the intrathecal approach used as the primary route of therapy, depending on the mechanism of pain. The highest daily morphine dose was 480 mg and 50 mg for epidural and intrathecal routes, respectively. The patients given the highest dosages were not necessarily those subjected to the longest treatment. The need for increased dosage seems to be related not only to changes in receptor sensitivity but also to changes in pain mechanisms. No case of threatening ventilatory depression was reported. Thirty-two departments had treated a few patients with chronic non-cancer pain conditions. Initial results were considered "excellent" in 11 departments, but at follow-up results were excellent in only one department. In addition to dislocation, occlusion of the catheters or leakage, injection pain was an obstacle to successful treatment. Pruritus urinary retention, and local infections were not reported as significant problems, but one case of meningitis was reported.

Neonatal EEG, cerebral evoked potentials, CT scan findings and their evolution were investigated in 42 neonates who eventually developed the West syndrome. In infants with perinatal hypoxia, the EEG displayed most often marked or maximal depression in the first week of life. The highly abnormal initial EEG improved progressively with time. The most frequent findings in early infancy was discontinuous tracing and persistent alternating tracing at 1-2 months, and absent sigma rhythms at 3-4 months. The VEP, AEP and CT scan also showed findings suggesting severe degree of brain damage. In infants with meningitis, the initial EEG was less depressed but the EEG abnormality persisted or worsened. In infants with prenatal causes the neonatal EEG was variable, ranging from a normal background EEG to specific abnormalities. The evolution of paroxysmal abnormalities was similar in all groups. There were no epileptiform discharges in early months. The appearance of hypsarrhythmia was preceded by focal and then multifocal spike or sharp wave discharges.

Prospective screening of an extremely high risk group of 137 infants cared for in the Newborn Intensive Care Unit of the James Whitcomb Riley Hospital for Children was undertaken during 1983. Auditory brain stem responses (ABR) were obtained utilizing a clinical evoked potential system (Madsen 2250). Patients were selected for screening prior to discharge or transfer to the referring hospital on the basis of one or more of the following criteria: birth weight less than 1250 grams; birth weight less than 1500 grams and ventilatory support; significant depression at birth (Apgars less than 3 and 6 at 1 and 5 minutes, respectively); seizures, meningitis, and/or sepsis. Of the original 137 infants tested, 82 passed the initial ABR, 22 conditionally passed, and 34 failed. Eighty-two infants had follow-up behavioral and audiometric testing while 20 infants died and 35 were lost to follow-up. Four infants had severe sensorineural hearing loss, each of whom had failed the initial ABR. None of the infants who initially passed or conditionally passed the ABR had sensorineural hearing loss on follow-up testing. High risk factors for sensorineural hearing loss in the neonatal period included: intraventricular/periventricular hemorrhage, apnea, family history, major malformations of the head and neck, and possibly hyperbilirubinemia and congenital infection. No relationship of sensorineural hearing loss with very low birth weight, hyponatremia, infection, seizures, or medications was found. On the basis of these data, it is suggested that electrophysiologic hearing screening of a high risk population may be delayed until 3 to 6 months of age to improve specificity of testing.

Central nervous system (CNS) involvement is a rare complication of chronic lymphoid leukaemia (CLL). The occurrence of lymphocytic meningitis in the course of CLL suggests either CNS involvement by the leukaemic process or infection (especially tuberculosis) related to continuous immunodepression. We report a case of CLL in which leukaemic cells had surface IgM and produced IgM kappa without significant depression of other immunoglobulins. When the patient developed meningitis, measurement of serum and CSF albumin IgG and IgM levels showed that 88% of CSF IgM resulted from local synthesis, while 70% of CSF IgG resulted from serum transsudation. These results suggest that a large number of neuromeningeal lymphoid cells produce the same class of IgM as leukaemic cells and therefore constitute a localization of the disease. Complete remission of the meningitis by intrathecal anti-leukaemic chemotherapy confirmed this hypothesis.

Three young infants with protracted diarrhea and malnutrition were successfully treated by means of intravenous nutrition, which included infusions of fat emulsion (Intralipid) and of fresh frozen plasma. Three to five weeks after termination of intravenous feeding, and after full recovery, they developed pneumococcal septicemia and meningitis. One infant died, and postmortem examination showed diffuse deposition of "intravenous fat pigment" in hepatocytes and in reticuloendothelial cells. In the two infants who recovered, follow-up studies did not disclose any primary derangement of immunologic function. We propose that the infused fat may have caused a temporary depression of immunologic defense mechanisms, predisposing these infants to the pneumococcal infection; the delay in onset of the infection might be attributed to a short-lasting protective effect of fresh frozen plasma which was included in the intravenous feeding regimen.

An 11-year-old girl developed a subacute illness characterized by fever, malaise, depression, and meningoencephalitis. The etiology remained elusive until her agglutinin titer against Brucella abortus rose from 1:20 to 1:320. Brucellosis is an uncommon illness in children, an neurological involvement has been described in only ten cases. Brucella meningoencephalitis is characterized by a lymphocytic pleocytosis and elevated protein in the cerebrospinal fluid. Patients respond well to specific therapy; it is important, therefore, to consider the diagnosis of brucellosis in patients with subacute meningitis of unexplained etiology.
