To evaluate the usefulness of 99Tcm-hexamethylpropyleneamine oxime (HMPAO) single photon emission computed tomography (SPECT) in suspected dementia we studied 160 consecutively imaged elderly patients from our hospital's memory disorder clinic. The diagnosis was based on clinical data, laboratory tests, neuropsychological examination, computed tomography (CT) and EEG. The patients were divided into six diagnostic categories: Alzheimer's disease (AD), multi-infarct dementia (MID), frontal lobe-type dementia (FTD), vascular encephalopathy not fulfilling the criteria of dementia, specific organic conditions, and psychiatric disorders. SPECT images were assessed without knowing the clinical diagnosis, and divided into AD pattern, FTD pattern, MID pattern, abnormal but unclassifiable, and normal. Twenty-three of 36 patients with clinical AD, 25/33 patients with clinical MID, and 2/5 patients with clinical TFD had compatible SPECT patterns. SPECT distinguished AD from MID in the majority (80%) of cases. In patients with depression or anxiety SPECT was abnormal in 16/21 cases, suggesting that SPECT may give early clues to the presence of an underlying organic disease in such elderly patients. Thus, SPECT with 99Tcm-HMPAO seems to be useful in the diagnosis of suspected dementia.

In a previous work we showed an alteration of erythrocyte filtration ability in patients with Alzheimer's disease according to their age and illness duration. This study has for aim to find a criteria of deformability that would be constant in all Alzheimer patients and would show a modification of red cell membranes. The erythrocyte filterability was studied in this present paper, in accord to Reid and Dormandy method using two values of depression (5 and 0 cm of water). These depressions correspond to the physiological values of blood pressure at the level of precapillary and capillary systems. The ratio between the result obtained at 5 cm and the result at 0 cm is constant in normal patient without organic disease and it is independent of age. At the opposite, this ratio increase very significantly in all Alzheimer patients, and this is not correlated to the initial value of filtrability. This ratio could be an index of the alteration of red cell membranes.

Of 317 consecutive cases seen in a dementia clinic, 19 (6%) had little or no objective evidence of cognitive impairment on clinical examination and extensive neuropsychological testing. Of the remaining 298 cases, 192 (64%) were diagnosed as probable or possible Alzheimer's disease (AD). Of the 19 nondemented cases, 8 (42%) were thought to have cognitive difficulty due to depression. In the AD group, only 4 cases (2%) were thought to be depressed and only 2 of the 4 met DSM-III-R criteria for major depression. There was no relationship between Hamilton Rating Scale for Depression scores and either cognitive or behavioral measurements of dementia severity, suggesting that the difference between the two groups was not due to underreporting by AD patients. The authors concluded that a tertiary care setting, depression is a common cause of cognitive complaints in persons without organic disease and a rare cause of excess morbidity in AD.

Temporomandibular joint (TMJ) disorders have been collectively grouped as myofascial pain-dysfunction syndrome (MPDS) or temporomandibular joint dysfunction syndrome (TMJDS). In the past, these terms have been used synonomously to describe a set of clinical signs and symptoms that include pain in the TMJ and muscles of mastication, limited or deviant opening of the mandible, and/or joint sounds. The present study segregated two major subgroups subsumed within this diagnostic classification and assigned them to a myogenic facial pain (MFP) group and a TMJ internal derangement (TMJID) group. Previous studies may have included both of these disorders as MPDS/TMJDS. While some signs and symptoms are similar, the primary differentiation is based on meniscus displacement present with TMJID patients and pain distribution patterns between the two groups. While MFP/TMJID patients comprise the majority of the facial pain population, a third major group of patients is encountered, being classified under the diagnostic appellation of atypical facial pain (AFP). Patients with AFP usually complain of vague and wandering pain in the maxilla or mandible; however, no identifiable source of infection or organic disease can be uncovered. One hundred fifty patients seeking consultation and care for facial pain met the criteria for inclusion into one of three clinical groups. The groups were compared for age, sex, duration of symptoms, bruxism and/or clenching habits, and disturbed sleep patterns. Differences in surface electromyographic levels from the facial and cervical muscles were also examined. Minnesota Multiphasic Personality Inventory (MMPI) scores from 95 subjects were compared with self-report measures of depression and anxiety. It was concluded that subcategorization of myofascial pain dysfunction patients into a MFP and TMJID group is justified on the basis of psychometric differences, clenching habits, masseter EMG levels, and male:female ratio. Furthermore, psychopathological factors are more significant among MFP and AFP subjects than TMJID patients.

Compared 30 mothers whose children were hospitalized for failure-to-thrive (FTT) to a normative group on standardized measures of perceived stress and depression. Child and maternal medical and demographic data were also taken. Standardized development and feeding assessments were done. Descriptive statistics, correlational analyses, and t tests were used to describe and examine group differences. FTT children were perceived overall as more stressful, less adaptable, more inconsolable, and more unhappy than were healthy children. Child characteristics associated with higher maternal stress levels were higher birth weight, absence of organic disease or behavioral feeding problems, and higher IQ. Maternal self-report of depression, attachment to her child, sense of competence in parenting, social isolation, and relationship to spouse were not different from the normative sample.

The objective of this prospective study was to test the hypothesis that 6 reportedly important psychosocial factors were useful criteria for diagnosing the irritable bowel syndrome. Ninety-seven new patients with entry complaints of abdominal pain, altered bowel habits, or both underwent full evaluation by board-certified or -eligible gastroenterologists in an outpatient setting. The independent measures were 6 questionnaires concerning anxiety, depression, stress, lack of social support, somatization, and abnormal illness behavior. The dependent measure, irritable bowel syndrome, was defined as the absence of an organic disease explanation for patients' entry complaints. Two other board-certified gastroenterologists, independent of the study, made this determination. Their rating was based on full review of transcripts of patients' clinic visits, laboratory data, and the results of a 9-mo telephone follow-up to patients and their physicians. Sixty-five percent of the sample had no organic disease explanation for the entry symptoms, thereby representing irritable bowel syndrome. The psychosocial predictors did not show a significant association with irritable bowel syndrome; the power of the study was 0.86. Post hoc analysis revealed that patients with organic disease, as well as patients with irritable bowel syndrome, had significantly more (p less than 0.01) psychosocial abnormality than normal subjects, which likely contributed to the inability of the psychosocial predictors to distinguish irritable bowel syndrome from organic disease. It was concluded that psychosocial criteria were of limited value in differentiating irritable bowel syndrome from organic disease but that they were determinants of health care seeking for the entire study group.

Thirty-one consecutive subjects suffering from oral dysesthesia and without detectable organic disease were seen in a university outpatient dental clinic. They were assessed with a screening test for psychiatric illness, the General Health Questionnaire, 28-item version (GHQ-28). Twelve subjects also completed the Irritability, Depression and Anxiety Scale (IDA). At the 4/5 cutoff on the GHQ, 51.9% of the patients showed evidence of psychiatric illness. The IDA appeared to be more sensitive than the GHQ-28 in terms of detecting psychiatric illness, especially depression, and 75% of the 12 subjects who completed both scales were found to be depressed on the IDA. These results were compared to results obtained by another cross-sectional study of different types of pain clinics in which the same scales were used to screen for psychiatric illness. The subjects with oral dysesthesia as measured by the IDA appeared to have psychiatric illness more often than the other subjects with chronic pain, except those attending a psychiatric clinic. The GHQ-28 results on the other hand showed less psychiatric illness in the latter group. Our findings indicate that psychiatric illness, especially depression, may play an important role in this disorder and that the IDA may be more sensitive than the GHQ for detecting depression.

Weight loss can herald the existence of an underlying serious disease. The purpose of this study was to ascertain the frequency of the involuntary weight loss at the Internal Medicine inpatient service of our Institution and the different conditions associated with it. The study was undertaken from March 1984 to February 1985. All patients who had lost at least 10% of their total body weight 6 months prior to admission were included. Those patients who had an evident organic disease, which could explain their weight loss, were excluded. A complete clinical history was performed in all cases; additional data concerning family and employment aspects and symptoms of depression were recorded. The evaluation also included screening laboratory examinations and specific diagnostic procedures. The study group consisted of 50 patients, 32 males and 18 females whose average age was 57.6 and 62.5 years, respectively. Mean average percentage of weight loss was 19%. The involuntary weight loss turned out to be clearly related to an organic cause in only 17 patients (34%), five of which had a malignant neoplasm. On the other hand, in 21 cases, factors such as stress inductors and depression seemed directly related to the involuntary weight loss. It is concluded that malignant diseases are not the pathology most frequently associated with unexplained involuntary weight loss in our Institution. Differential diagnosis must consider other organic and psychiatric disorders. Particular attention should be paid to those data relative to dietary habits, the patient's family and symptoms of depression in order to attain a more integral view of the patients.

The Fuld Object Memory Evaluation (Fuld, 1981) was administered to 80 elderly adults (aged 60 to 90 years) who were hospitalized for evaluation and treatment of primary degenerative dementia (PDD), other organic disorders (e.g., Parkinson's disease or multi-infarct dementia), or major depression. Although mean performance in each of the diagnostic groups was below normative levels reported by Fuld (1981), PDD patients performed significantly more poorly than those with depression or other organic disorders. Analysis of subscore patterns failed to support the hypothesis of a selective memory deficit in depression, and substantial overlap in scores was observed between the depressed group and patients with organic disorders other than PDD. Object Memory Evaluation performance was influenced by global mental status and secondary psychiatric diagnoses, but not by education, age, or physical health.

The dexamethasone suppression test (DST) has been used in psychiatric pathology for about 10 years. Carroll et al. consider this test to be specific of endogenous depression. According to these, and many other authors, approximately 55% of patients with endogenous depression show a positive response to the test, whereas a positive response is observed in only 4% of normal subjects or patients with psychiatric disorders other than major depressive disorders. The DST was performed in 162 psychiatric inpatients (5 with organic disease, 28 with schizophrenic disorders, 17 with major affective disorders, 5 with obsessive compulsive disorders, 103 with dysthymic disorders and 4 unclassified). Dexamethasone (1 mg) was administered orally at 11 p.m., and plasma cortisol concentration was measured the following day at 16 p.m. Response to the test was positive in 53% of patients with major affective disorders, 25% of those with schizophrenic disorders, 60% with obsessive compulsive disorders and 18% with dysthymic disorders. There was no statistical difference in the results according to age, sex ratio, family history of depression or duration of the disorders. Only two variables were close to the P less than 0.05 level of statistical significance: severity of the disorders and early morning awakening. DST sensitivity, therefore, would appear to be about 50% in major affective disorders, but this test is not specific as it may also be positive in other psychiatric disorders. A positive dexamethasone suppression test may be regarded as a sign of severity of psychiatric disorders.
