We describe two human immunodeficiency virus (HIV)-infected patients with syphilitic cerebral gummas. Both patients presented with a seizure disorder associated with an isolated, peripherally located, contrast-enhancing lesion of the brain on CT. Cranial MRI performed on one patient revealed dural thickening in the region of the lesion. A brain biopsy in that patient revealed a lymphoplasmacytic infiltrate with extensive perivascular inflammation. Clinical manifestations, radiographic resolution of the lesions, and a decline in nontreponemal serologic tests for syphilis followed high-dose aqueous penicillin therapy in both patients. These patients illustrate that (1) cerebral mass lesions occurring with HIV infection may result from syphilis; (2) seizures may be the presenting manifestation of this form of neurosyphilis; and (3) high-dose, intravenous, aqueous penicillin is effective in treating these lesions.

Forty-seven HIV-seropositive children were investigated by EEG and evoked potentials (BAEP, SEP). Twenty-three children were symptomatic (P2), 8 seropositive without symptoms (P1), and 16 children were less than 15 months of age (P0). Some of them were investigated at different stages of HIV infection. During the neonatal period, 7 newborns of drug-addicted mothers had seizures and frequent spikes and sharp waves in their EEGs. Among (P2) children 6/23 showed background slowing and 1 had rhythmic theta activity (6 with and 1 without neurological symptoms). In BAEP, bilateral prolonged interpeak latencies (IPL) were found in 1 child with severe AIDS encephalopathy. Side differences greater than or equal to 0.4 ms in IPL were seen in 2 (P2), 1 without and 1 with neurological symptoms. A late onset was seen in 2 (P1) and 4 (P2) children. Median SEPs were normal in 24/26 patients; N20/N13 amplitude ratio was reduced in 2 (P1) patients. EEG and BAEP revealed nonspecific abnormal features in HIV encephalopathy. The the progression of the disease. However, also in the symptomatic group, normal results of EEG and BAEP dominated. SEP in the symptomatic group revealed only normal values. For monitoring the effectiveness of AZT treatment in HIV encephalopathy, EEG seems to be a relevant investigation; for evoked potentials more data and experience are needed.

This article discusses the wide range of neurologic complications of HIV infection according to degree of advancement of systemic HIV disease. The focus is principally on those disorders that appear at least in part to be directly related to HIV: AIDS dementia complex, peripheral neuropathy, and myopathy. Unusual disturbances such as seizures and transient neurologic disorders are also discussed.

Fifty-two patients at various stages of human immunodeficiency virus (HIV) infection who had one or several epileptic seizures in the course of that disease were retrospectively studied from 1985 to 1990. Thirty-five percent of these patients were in overt clinical AIDS at the time of the seizure(s). AIDS was revealed by a seizure in 2 cases. Generalized seizures were observed in 71 percent of the patients, and partial seizures in 29 percent. Electroencephalograms showed signs of brain irritation in only 19 percent of the cases. The cause of epileptic seizure(s) could be determined in 36 patients: cerebral toxoplasmosis in 23 cases; progressive multifocal leucoencephalitis in 2 cases; HIV encephalopathy in 3 cases; iatrogenic cause in 4 cases; meningoencephalitis in 3 cases and neurosyphilis in 1 case. No cause other than HIV infection was found in 16 patients. These findings confirm those of previous studies. In about one-third of AIDS patients epileptic seizures are the only clinical manifestation of viral central nervous system infection.

Because of the growing incidence of neurological disorders in HIV-infected patients, an early detection of the disease seems to be of paramount importance, especially in asymptomatic subjects. By using electroencephalography coupled with computerized spectral analysis and "mapping" (EEG-CSA), paroxysmal sharp activity was detected in 26 patients belonging to different stages of HIV infection. Seven of them (27%) were also symptomatic, (table; see text) showing signs of convulsant disease. The presence of focal or generalized paroxysmal activity, often associated with seizures, might suggest an early localization of HIV in cortical structures.

A case is reported of reversible panhypogammaglobulinemia in a human immunodeficiency virus (HIV)-infected patient. Onset and resolution were temporally correlated with initiation and termination, respectively, of diphenylhydantoin therapy for a possible seizure. A rapid alteration in peripheral T-cell subpopulations was also noted in association with diphenylhydantoin administration. This case is compared with previous reports of diphenylhydantoin-associated hypogammaglobulinemia in non-HIV-infected patients. In addition, the case is discussed with regard to possible deleterious effects associated with the use of diphenylhydantoin as therapy for HIV-associated seizures or as an antiretroviral agent in HIV disease.

Maternal drug addiction has increased in an alarming way over the last ten years. Therefore, the withdrawal syndrome in the newborn has also increased. 53% of the newborns (of chemical dependent mother) studied from 1985 to 1989 in HCP have presented this syndrome. We have analysed: perinatal, neonatal and maternal factors, and their clinical features and treatment: There is a great incidence of perinatal asphyxia, acidosis, premature rupture of the fetal membranes, etc. The newborns are usually premature or of low birth weight for their gestational age. They present diverse pathology: syphilis, HBsAg +, HIV +, gonorrhea, congenital malformations, etc. The mothers are often prostitutes, belong to a low socioeconomic status, have had previous abortions and have had no control of the actual pregnancy, etc. The syndrome of abstinence presents with: jitteriness, sweating, high-pitched or continuous crying, vomits, diarrhea, and even seizures. The neurological and digestive manifestations are the most difficult to treat. The treatment consists of general measures (little stimulation dim light, etc.), phenobarbital, and chlorpromazine.

An analysis was made of the clinical, pathological and radiological data relating to 117 requests for cranial CT on 83 patients who were HIV positive or had AIDS in one year at St Mary's Hospital. Central to the design was grouping of the patients according to clinical presentation. The aim was to establish whether there was evidence to support the view that, because of their immunocompromised state, these patients may commonly harbour serious, potentially treatable intracranial disease without the usual overt clinical signs. No patient who was only HIV antibody positive had treatable intracranial disease without focal neurological signs. In patients with AIDS, treatable or potentially treatable lesions were mainly confined to those with objective neurological signs or seizures. There is little evidence in this data to support the original hypothesis. While it would be inappropriate to advise that CT should never be carried out in the absence of focal signs or seizures, the results of this study should be useful in ascribing an appropriate degree of urgency to requests for cranial CT in these patients.

The incidence of measles in the United States dramatically increased in the 1980s, from a low of 1,497 cases in 1983 to over 17,000 cases in 1989. Family physicians can help reverse this trend by following the revised immunization schedule, which includes a measles-mumps-rubella (MMR) booster for preschool-age children. New guidelines also recommend that either the two-dose MMR schedule or serologic evidence of immunity be required for all persons entering college or employed in the medical field. Immunization policies for physician's offices should ensure that all office staff have acquired measles immunity and that a triage policy separating patients with rash from those with other illnesses is utilized. Mild upper respiratory illness, a history of seizures, nonanaphylactic egg allergy and asymptomatic human immunodeficiency virus infection are not contraindications to measles vaccine. All cases of measles should be reported to the local health department.

In an HIV-seropositive patient presenting generalized tonic-clonic seizures, magnetic resonance imaging and cerebrospinal fluid examination disclosed the signs of a previous subarachnoid bleed. No vascular malformation was observed with cerebral angiography. Laboratory tests revealed an autoimmune thrombocytopenia. A spontaneous subarachnoid hemorrhage induced by thrombocytopenia should be considered when investigating HIV patients presenting even non-specific neurological symptoms.
