A 52-year-old man had a prolonged history of nondeforming migratory polyarthritis and a short episode of pericarditis preceding the onset of bilateral vitreitis and retinitis. The clinical course was characterized by progressive deterioration of vision, increasing lethargy, and dementia, leading to coma and death from pneumonia (21 months later). No intestinal manifestations were recorded. Both eyes, which were removed postmortem, disclosed numerous PAS-positive macrophages throughout the inner retina and vitreous. Electron microscopic studies of the macrophages displayed intracytoplasmic, degenerating, rod-shaped bacteria and membranous structures identical to those seen in the intestine, brain, heart, and other tissues of patients with Whipple's disease. Clinicians should include Whipple's disease, and reticulum cell sarcoma, in the differential diagnosis of patients with bilateral retinitis and vitreitis, especially if these disorders are associated with CNS manifestations.

This report is to investigate neuropathological changes of the thalamus observed in progressive supranuclear palsy. Six autopsy cases were examined. They were 5 males and a female, whose age was between 57 and 72 years old. They developed dementia in various degrees and three of the cases showed periodic stuporous state and akinetic mutism in the last stage. The paraffined thin-sections were stained with hematoxylin-eosin, luxol-fast-blue, Holzer, modified Bielschowsky, Gallyas and anti-tau stainings. The histological changes were evaluated in the aspects of neuronal loss, fibrillary gliosis and neurofibrillary tangles. In conclusion, there were three types in six cases. The first was seen in two cases and that there appeared many Alzheimer's neurofibrillary tangles (NFTs) in medial nuclei, lateral and ventral nuclei as well as zona incerta and reticular nucleus. The second was observed in two cases and that the loss of nerve cells was severe, especially in medial nuclei and the dorsal part of lateral and ventral nuclei and fibrillary gliosis was observed beyond the lesions of neuronal loss. The third was that the appearance of NFTs was moderate in number and neuronal loss was minimal. Moreover, neuronal loss and NFTs of zona incerta were common in these cases. Argentophilic fibrillary inclusions were observed in the neuropil and astrocytes in all cases. It is important to investigate the correlations between neuropathological changes and clinical manifestations, especially in the peculiar type of dementia observed in PSP. The thalamic changes of PSP may play an important role in causing stuporous state and akinetic mutism as well as subcortical dementia.

Involvement of the central nervous system (CNS) is common in patients with advanced disease due to human immunodeficiency virus (HIV). Symptoms range from lethargy and apathy to coma, incoordination and ataxia to hemiparesis, loss of memory to severe dementia, and focal to major motor seizures. Involvement may be closely associated with HIV infection per se, as in the AIDS dementia complex, but is frequently caused by opportunistic pathogens such as Toxoplasma gondii and Cryptococcus neoformans or malignancies such as primary lymphoma of the CNS. The clinical presentations of attendant and direct CNS involvement are remarkably non-specific and overlapping, yet a correct diagnosis is critical to successful intervention. Toxoplasmic encephalitis is one of the most common and most treatable causes of AIDS-associated pathology of the CNS. A great deal has been learned in the last 10 years about its unique presentation in the HIV-infected patient with advanced disease. Drs. Benjamin J. Luft of the State University of New York at Stony Brook and Jack S. Remington of the Stanford University School of Medicine and Palo Alto Medical Foundation's Research Institute have studied T. gondii for many years and are two of the leading experts in the field. This commentary comprises an update of their initial review (J Infect Dis 1988;157:1-6) and a presentation of the current approaches to diagnosing and managing toxoplasmic encephalitis in HIV-infected patients.

Delirium, an acute confusional state, is an organic brain syndrome that manifests deficits in attention, irrelevant or rambling speech, and other cognitive deficits. Its symptoms often fluctuate over the course of the day, and patients may be hyperactive--for example, restless and screaming--or hypoactive--for example, quiet, inactive, and stuporous. Occurring in approximately 20% of hospitalized elderly patients, delirium is the most common psychiatric syndrome in acutely ill general medical and surgical patients. Fifteen to 30% of delirious patients expire, and others are prone to a variety of complications: falls, pressure ulcers, oversedation, dehydration, and others. Almost any acute illness can cause delirium in the elderly, but the most common offenders are acute infections and drugs. Many patients have a pre-existing dementia. The first step in arriving at a correct diagnosis is to distinguish delirium from other psychiatric syndromes that can cause confusion, such as dementia, depression, schizophrenia, and mania. Once delirium is established, a comprehensive general examination and a mental status examination is required. Routine laboratory and radiologic tests are directed at the common metabolic and infectious disorders that precipitate delirium. Treatment is directed at the underlying acute illness. In all patients, it is important (1) to treat the underlying acute illness, (2) to provide appropriate fluid and electrolytes, (3) to discontinue any unnecessary drugs, and (4) to allay the patient's fear and agitation through the use of simple, repetitive instructions, orientation cues, and by limiting the use of physical restraints. If psychotropic medications are needed to treat psychotic symptoms, to prevent patients from harming themselves or others, or to facilitate necessary diagnostic and therapeutic interventions, then haloperidol is the drug of choice in most instances. Drugs with anticholinergic properties should be avoided.

Inpatient and community-based care can be complementary in relation to the management of HIV disease. Medical records from 200 inpatients of Chikankata Hospital near Lusaka, Zambia and 200 home based patients were examined and compared for the common symptoms of presentation of HIV disease, associated opportunistic infections, and treatment protocols. Drug costs of both groups were also compared. The most common respiratory symptoms in the 2 groups are cough, chest pains, weight loss, and hemoptysis. Treatment employed for these symptoms were cortimoxazole, penicillin V, erthromycin, and tetracycline. Acetyl saliclic acid and paracetamol were used for pain relief in both groups. Gastointestinal system symptoms for both groups were diarrhea, weight loss, abdominal pain, and vomiting. Cotrimoxazole and metronidazole were used in treating diarrhea. Additional treatment protocol for the 2 patient samples included oral rehydration therapy for dehydration, antacid or bismuth subsalicylate for diarrhea and enteritis, and mycostatin for oral candidiasis. Central nervous system symptomatology included headache, dementia, neckace, and lethargy. Chloramphenicol was employed in treating bacterial meningitis. Diazepam and chlorpromazine were effective for restless patients. Genito-urinary system symptomatology for the 2 groups included dysuria, genital ulcers, hematuria, viral warts, and buboes. Antibodies were used for sexually transmitted diseases and infections. Skin symptomatology included rash and dermatitis, herpes zoster, abscess, kaposi's sarcoma, ulcers, furunculosis, and discharging anal sinus. In treating these symptoms, hospital based care and home based care were similar. Overall, it was found that hospital treatment protocols were detailed, expensive, and time consuming. Furthermore, hospital treatment for HIV positive patients is more expensive than HIV negative patients; hospital costs for 50 HIV negative patients totaled US$415.94 compared to US$1204.98 HIV positive/PTB negative patients and US$1705.62 for HIV positive/PTB positive patients. Drug cost/patient admission is increased by 469% if HIV positive. (author's modified).

Propionic acidemia usually presents in the newborn period with severe metabolic acidosis and lethargy. A 31-year-old man with adult onset chorea and dementia had propionic acidemia due to propionyl CoA carboxylase deficiency. Metabolic investigations may prove useful in patients with movement disorder of unknown etiology.

The paper describes the psychiatric status on the basis of 76 patients with acquired immune deficiency syndrome. There is considerable difference between the different stages of the disease. The disorders are divided into groups following the German and French psychopathological tradition, where the incidence is dependent on the underlying complaint. 50% of the patients suffered from chronic psychoorganic disorders (34% organic personality disorders, 16% dementia). 9% suffered from an acute psychosis caused by complications and founded on substantial physical illness. 3 patients showed symptoms of a (under given circumstances) hitherto unknown endoform psychosis. In 9% of the patients, psychoreactive disturbances (anxiety and reactive depression) were observed. Two infants had congenital development deficiencies. 25% of the patients were without any psychopathology. Patients showing organic personality disorders mostly resemble each other to such a degree as to form a separate group. We suggest to name this group according to the most prominent psychopathology as "AIDS-lethargy". This status is characterised by a specific apathy, tiredness and indolence of the patients combined with the lack of emotional participation related to their own destiny. AIDS-lethargy is the first manifestation in appearance of the HIV infection of the brain itself. Another sequel of the brain infection is AIDS dementia which can be classified as "subcortical dementia" and differs from the more current forms of dementia clinically. Affected are mainly neuropsychologic functions like arousal, attention, mood and motivation, whereas the hallmarks of cortical involvement-aphasia, agnosia and apraxia-are not present. Supplementary findings (EEG, CCT, CSF): The group of patients with chronic psychoorganic disorders differs significantly from the group with psychoreactive disorders and normals. Pathological EEG and CCT are more frequent in psychoorganic disorders. CSF-test-including the intrathecally synthesized antibodies against HIV-does not show traceable variation in either group. There are four problems which may be combined in a given acute psychopathological HIV-syndrome: 1. Being member of a risk group with its reactive, psychosocial and personality problems. 2. Individual mental and emotional reaction to the fact of infection 3. Chronic psychoorganic disturbances. 4. Acute organic psychoses as a result of complications and other physical illness.

Two patients with early stage chronic lymphocytic leukemia were found to have meningeal involvement. The diagnosis was confirmed by cerebral spinal fluid cytology in the first patient and by flow cytometric analysis in the second patient. Both patients responded well to intrathecal chemotherapy and cranial irradiation. Central nervous system infiltration by tumor cells has rarely been described in chronic lymphocytic leukemia but must be considered in all patients regardless of stage who present with lethargy, dementia, or focal neurologic signs.

A persistent vegetative state (severe dementia) developed in a 30-year-old man following hypoglycemic coma. Despite the poor clinical outcome, sensory evoked response recovered between 6 and 34 months after the insult. The cerebral blood flow level at rest after 34 months was slightly above the normal range. This finding contrasts with the low cerebral blood flow regularly reported in patients who are comatose or stuporous following severe brain hypoxia-ischemia.

From 1972-1974, 228 children began treatment for acute lymphocytic leukemia and were prospectively assessed for neurologic complications. After CNS irradiation (2,400 rad) and intrathecal methotrexate (MTX), they received weekly intravenous maintenance therapy with MTX alone (40-60 mg/m2; 20 patients) or MTX (10-30 mg/m2) with other drugs (208 patients). Signs of leukoencephalopathy appeared in 11 children (nine without CNS leukemia) after 4-15 months of IV MTX alone, and included lethargy, seizures, spasticity, paresis, drooling, and dementia. Before or during the clinical onset, EEG frequencies slowed (all ten patients tested). Radionuclide scans showed periventricular accumulation of 99mTc (9/11 patients) and remained abnormal for greater than or equal to six months in eight patients. Cranial computed tomograms or neuropathology findings (five patients each) demonstrated leukoencephalopathy (nine patients) and radiation-related microangiopathy (ten patients). Severe neurologic and neuropsychologic dysfunctions were present in four long-term survivors.
