Abstract
OBJECTIVE The authors conducted a prospective study of the clinical utility of the four DSM-III-R subtypes of primary degenerative dementia of the Alzheimer type (with delirium, with delusions, with depression, or uncomplicated) and acute psychiatric hospitalization for treatment of these subtypes. METHOD The subjects were 120 consecutive inpatients with Alzheimer's disease, most of whom had behavioral abnormalities. Each subject received detailed physical, neurological, psychiatric, and mental status examinations. The presence or absence of specific behavioral problems was also documented. Patients were treated with medication, psychotherapy, and behavioral techniques. RESULTS While all patients could be assigned to one of the four DSM-III-R behavioral subtypes, the uncomplicated subtype did not accurately reflect the burden of behavioral symptoms in the patients who did not have delirium, delusions, or depression. Each behavioral subtype responded in a characteristic way to inpatient treatment, as reflected by changes in scores on four psychometric scales used to assess cognitive impairment, psychiatric symptoms severity, and level of functioning at admission and at discharge, as well as by changes in residential setting following hospitalization. Half of all patients admitted from their homes and two-thirds of those with depression were able to go home following discharge. CONCLUSIONS Behavioral syndromes in Alzheimer's disease should not be overlooked, because they have both clinical and prognostic significance. Short-term psychiatric hospitalization is effective and efficient for achieving the goal of returning patients to their homes and for safely implementing specific treatments in this frail population, and it may reduce the need for institutionalization.

Abstract
The control of accommodation is an essential requirement during the clinical optometric assessment of distance vision. Accordingly, the aim of the present study was to examine the steady-state accommodative response during a number of conventional clinical procedures carried out at a viewing distance of 6m (20 feet). Accommodation was measured subjectively to Snellen letters using a Hartinger coincidence optometer during distance viewing, simulated retinoscopy and following the introduction of cylindrical and prismatic lenses in 13 visually-normal, young adults. No significant change in the mean accommodative response was induced by any of the techniques described, with subjects exhibiting a lead of accommodation of approximately 0.25D for all conditions. The results demonstrate the robustness of accommodation to apparently substantial changes in stimulus conditions.

Abstract
The nucleotide sequence of a murine monoclonal antibody (CB-mab-p24/13-5) against p24 core protein of the human immunodeficiency virus (HIV-1) was determined for variable regions of the heavy and light chain, respectively. Genetic elements encoding the VDJH- and VJL-regions of the antibody were generated from RNA by the polymerase chain reaction, cloned into the vector pICEM 19R and sequenced. Synthetic peptides, 10 amino acids overlapping served for the localization of the epitope. The residues 152-156 within the p24 sequence contain the epitope.

Abstract
Phase extraction pattern recognition is a special case of nonlinear matched filtering. The phase extraction procedure is executed on the input function's Fourier transform as well as on the filter function's Fourier transform, both of which are manipulated for correlation purposes. This novel process is examined theoretically, by computer simulations and laboratory experiments. The implementation of a coherent electro-optical phase extraction pattern recognition system demonstrates the advantages of this new approach.

Abstract
Four major neutralizing regions of the human immunodeficiency virus type 1 (HIV-1) envelope glycoprotein were identified and characterized with a panel of 80 HIV-1 antibody-positive human sera. Levels of neutralizing antibodies against the HIV-1 strains IIIB, SF2, and RF were compared with reactivity in ELISAs against peptides that correspond to certain regions of the HIV-1 envelope. A correlation between high neutralizing activity and strong seroreactivity against specific peptides suggested that the corresponding regions might be involved in neutralization. This was further substantiated by using peptides to inhibit neutralization by a panel of 10 HIV-1 antibody-positive sera. The positions of three neutralizing sites, defined earlier mostly by antisera from animals, were confirmed in the present study. Human sera thus recognize the strain-specific third variable region of gp120 (amino acids 304-318), the C-terminal end of gp120 (amino acids 489-508), and the conserved region in the intracellular part of gp41 (amino acids 732-746). It is likely that these different regions mediate help rather than self-sufficient neutralization. Furthermore, a human neutralizing region was detected in a conserved part of gp41 (amino acids 647-671). Accordingly, neutralizing antibodies directed to this region were found to be cross-reactive between HIV-1 strains. Peptides corresponding to these four regions were able to inhibit neutralization mediated by serum from HIV-1 antibody-positive individuals. These results indicate that this conserved B-cell epitope of the HIV-1 envelope elicits a virus-neutralizing antibody response during natural infection in humans and may therefore be considered for inclusion in a vaccine against HIV-1.

Abstract
Lithium-induced delirium occurring in geriatric patients with serum lithium levels that are within the "therapeutic" range (less than 1.5 mEq/L) has been described in the literature. We present a case that illustrates three major issues regarding this syndrome: (1) differentiating lithium-induced delirium from a recurrence of a chronic psychiatric disorder; (2) the use of the electroencephalogram in supporting this diagnosis; and (3) factors that may increase a patient's vulnerability to delirium while on lithium. A brief review of the most relevant literature is then presented. We conclude that lithium-induced neurotoxicity should be suspected in any patient receiving lithium who develops delirium, regardless of the serum level, and that immediate discontinuation of the medication be considered.

Abstract
The safety and efficacy of pentigetide (Pentyde) nasal solution, administered as 1 mg into each nostril four times daily, was compared with placebo for controlling symptoms associated with seasonal allergic rhinitis. This was a randomized, multicenter, double-blind, parallel-group trial involving 431 patients divided equally between pentigetide and placebo treatment. The study was conducted during the 1986 spring allergy season and consisted of 1 week of baseline followed by 2 weeks of treatment. Physicians evaluated the frequency and severity of nasal symptoms at study entry (day 1) and the final visit (day 22). Physicians and patients assessed the global condition of the patient at the end of the study and patients also recorded the severity of symptoms in a daily diary. Pentigetide-treated patients showed a statistically significant greater reduction in the frequency (P = .004) and severity (P = .05) of total nasal symptom score (sneezing, nasal congestion, and rhinorrhea) and in the individual nasal symptom scores compared with placebo-treated patients. Diary results showed consistently lower total nasal symptom scores on each treatment day for pentigetide-treated patients (P = .02). Both the physicians and patients globally rated more pentigetide-treated patients improved than placebo-treated patients. The incidence and types of adverse experiences were similar between treatment groups and there were no reports of sedation or fatigue in the pentigetide group. No clinically significant changes occurred for laboratory tests, physical examination parameters or vital sign measurements. Pentigetide nasal solution was safe and effective for the treatment of seasonal allergic rhinitis.

Abstract
Recent reports supporting the use of lithium carbonate as an adjunct to tricyclic antidepressants for the treatment of refractory depression have not utilized standardized tricyclic antidepressant therapy, nor have they addressed the efficacy of lithium augmentation in a geriatric population. A 3-week open trial was added to the medication regimen of 15 elderly depressed inpatients who had already failed 4 weeks of therapeutic levels of nortriptyline. Treatment response was determined by the 17-item Hamilton Rating Scale for Depression (HAM-D). Two of 15 partial responders before lithium augmentation became complete responders. Of the remaining 13 "nonresponders" before lithium augmentation, one had a complete response, 7 had a partial response and 5 remained nonresponders. Although there was a mean HAM-D change of 8.3 points after lithium augmentation (24.7 +/- 5.9 to 16.4 +/- 6.8, p less than .001), when considering the previously reported similar efficiency of extended nonaugmented nortriptyline, these data do not strongly support lithium augmentation in elderly subjects who fail to respond after 4 weeks of nortriptyline. Further study is needed to determine what role, if any, lithium augmentation should play in the treatment of geriatric depression.

Abstract
The importance of the dependence on single amino acids in the V3 region of HIV-1 gp120 was evaluated for virus neutralization and antibody-dependent cellular cytotoxicity (ADCC). Synthetic overlapping 15-mer peptides and a set of omission peptides covering amino acids 301-317 were used. Sera from 29 HIV-1-infected individuals at different stages of disease were tested for neutralization, ADCC and specific IgG reactivity. Six HIV-1 neutralizing monoclonal antibodies (mAb) acted as controls. All mAb reacted with a region (amino acids 304-318) of gp120, previously shown to induce neutralizing antibodies. The amino acids essential for reactivity were identified to be within the sequence GPGR (amino acids 312-315). The importance of this region for occurrence of neutralizing antibodies in infected humans was investigated using the same set of peptides. Out of 29 individuals, 21 were found to have neutralizing antibodies in titres between 100 and 1000. Among the neutralization-positive sera, 17/21 (81%) reacted with amino acids 304-318, compared with only one of eight sera (13%) negative in neutralization. When any of the four amino acids G, P, G or R were deleted, the seroreactivity decreased considerably. The conserved sequence GPGR was therefore considered to be the most important for neutralization in this region in human sera as well. Thus, the conserved sequence GPGR in the V3 region of gp120 is critical for virus neutralization by human HIV-1-specific antibodies.

Abstract
Neuropathologic and neurochemical correlates of psychosis were determined using brain tissue from 27 autopsy-confirmed cases of Alzheimer's disease. The densities of senile plaques and neurofibrillary tangles were determined in the middle frontal and superior temporal cortex, the prosubiculum, and the entorhinal cortex of the hippocampus. The concentrations of norepinephrine, dopamine, and serotonin, the metabolites of these biogenic amines, and the specific activity of choline acetyltransferase were also determined in these four cortical regions as well as in the substantia nigra, thalamus, amygdala, and caudate nucleus. Psychosis was associated with significantly increased densities of senile plaques and neurofibrillary tangles in the prosubiculum and middle frontal cortex, respectively, with trends toward increased densities of these lesions in the other areas examined. This finding is consistent with the increased rate of cognitive decline that accompanies this behavioral disorder. Psychosis was also associated with the relative preservation of norepinephrine in the substantia nigra, with trends in this direction for five of the remaining seven brain regions examined, and a significant reduction of serotonin in the prosubiculum that was accompanied by trends toward reduced levels of serotonin and 5 hydroxyindoleacetic acid in the remaining regions. The profile of neuropathologic and neurochemical changes associated with psychosis is distinct from that previously reported for major depression in the context of primary dementia.

Abstract
We longitudinally evaluated the neuropsychological functions, rate of progression, and waking EEG findings in 17 patients with probable Alzheimer's disease (AD) with delusions and hallucinations, and compared them with those of matched AD patients without delusions and hallucinations. AD patients with delusions and hallucinations had a more rapid rate of decline, as measured by the Mini-Mental State Examination, a specific defect in receptive language, and a greater frequency of aggression and hostility. Visual EEG analysis showed that these patients had a significantly greater proportion of moderately abnormal EEGs, and spectral analysis confirmed the increased amount of delta and theta activity. These data demonstrate that AD patients with delusions and hallucinations have a greater degree of cerebral dysfunction and a relatively focal neuropsychological defect, which may indicate a localized pathologic abnormality.

Abstract
Prospective psychiatric evaluations were performed as part of a longitudinal study of 32 demented patients who met criteria for the histopathological diagnosis of Alzheimer's disease at the time of death. Psychosis and major depressive disorder emerged in 15 (47%) and 7 (22%) patients, respectively, none of whom had a history of either behavioral disorder prior to the onset of dementia. The prevalence of psychosis increased with increasing dementia severity, was associated with more rapid cognitive decline, and once present was often persistent. In this regard, the emergence of psychosis in the context of Alzheimer's disease appears to be a poor prognostic sign. In contrast to its relationship to cognitive impairment, psychosis was not associated with an increased mortality rate.

Abstract
We performed a prospective, naturalistic study using standardized clinical rating scales to characterize the effect of electroconvulsive therapy (ECT) on mood, cognition, and medical status in late-life depression. Over a 16-month period, 40 patients aged 60 years and over who fulfilled DSM-III criteria for a major depressive episode received a total of 42 ECT courses. Three patients (7%) developed significant medical complications: one had a syncopal episode due to arrhythmia, and two had symptomatic vertebral compression fractures. Confusion was noted during 13 courses (31%) and persisted at discharge in four (10%). More than half the patients were either psychotic or demented on admission, and all but three had been either unresponsive or intolerant to pharmacotherapy. All patients experienced a decrease in their depressive symptoms and more than two thirds were in complete or partial remission at discharge. Patients with psychotic depression experienced a greater improvement than patients with nonpsychotic depression, and patients with organic mental disorders experienced the same improvement as other patients. This study confirms that ECT is a safe and effective treatment of depression in late life.

Abstract
OBJECTIVE AND METHOD Sleep disturbances are commonly reported by victims of extraordinary stress and can persist for decades. This study was designed to test the hypothesis that survivors of the Nazi Holocaust would have significantly more and different sleep problems than depressed and healthy comparison subjects and that the severity of the survivors' problems would be correlated with length of time spent in a concentration camp. Forty-two survivors, 37 depressed patients, and 54 healthy subjects of about the same age, all living in the community, described their sleep patterns over the preceding month on the Pittsburgh Sleep Quality Index, a self-rating instrument that inquires about quality, latency, duration, efficiency, and disturbances of sleep, use of sleep medication, and daytime dysfunction. RESULTS The survivors had significantly greater sleep impairment than the healthy comparison subjects, as measured by all subscales of the index, but had less impairment than the depressed patients except on the sleep disturbances and daytime dysfunction subscales. However, for specific items within these subscales, survivors had significantly more frequent awakenings due to bad dreams and had less loss of enthusiasm than the depressed subjects. Sleep disturbances and frequency of nightmares were significantly and positively correlated with the duration of the survivors' internment in concentration camps. CONCLUSIONS These findings suggest that for some Holocaust survivors, impaired sleep and frequent nightmares are considerable problems even 45 years after liberation.

Abstract
Amino acid sequences inducing neutralizing antibodies to HIV-1 were sought. Murine monoclonal antibodies (MAbs) were characterized by their reactivity with the envelope precursor gp160 or the Escherichia coli recombinant DNA products pB1 and pE3 representing the carboxy- and amino-terminal halves of mature envelope gp120. Fine mapping of the MAb determinants was performed using defined 15-mer synthetic peptides spanning the entire envelope gp120 region of HIV-1. One group of MAbs recognizes epitopes (amino acids 304-323) occurring in a small region with variable and conserved amino acid sequences of gp120. These MAbs mediate neutralization of the HIV-1 strain HTLV-IIIB (HIV-1IIIB) which was used for immunization. Nine out of 11 primary HIV-1 isolates were neutralized well or moderately well. In addition, prominent serological reactivity was noted with peptide sequences of strains of various European or American origins, but not with two HIV-1 strains of African origin. The cross-reactivity contrasts with previously described type-specific reactions to other sequences of this region. The reactivity to the short conserved site GPGR with its flanking amino acids may explain the broad sequence cross-reactivity seen with our neutralizing MAbs. Two other MAbs recognize conserved epitopes (amino acids 79-103) situated in the amino-terminal region of gp120. These MAbs did not neutralize HIV-1IIIB.
