Beyond the surface: Understanding obsessive symptoms and body perceptions, from shape concerns to fear of blushing.

INTRODUCTION: Recent reclassifications have expanded the understanding of Obsessive-Compulsive Disorders (OCDs), now incorporated into a broader category known as Obsessive-Compulsive Disorder and Related Disorders (OCRDs). This study sought to assess obsessive-compulsive symptoms and body uneasiness among outpatients seeking treatment for Eating Disorders (ED). Additionally, we aimed to explore associations and potential mediation effects between obsessive-compulsive symptoms and body uneasiness. This investigation extended beyond concerns related solely to body shape and weight, encompassing fears associated with specific body components (such as facial features, abdominal region, and limbs) or functions (including sweating, blushing, emitting noises, and releasing odors). METHODS: Psychometric assessments included the Obsessive-Compulsive Inventory-Revised (OCI-R) and the Body Uneasiness Test (BUT). Statistical analyses involved bivariate correlations, linear regression, and mediation analysis to explore the associations and potential mediation effects between obsessive-compulsive symptoms and different manifestations of body uneasiness. RESULTS: The sample (N = 210) demonstrated substantial obsessive-compulsive symptoms and notable body discomfort. OCI-R scores positively correlated with various dimensions of body dissatisfaction, including shape, weight, and specific body components or functions. Linear regression revealed significant associations between OCI-R scores and overall body uneasiness (BUT-A) as well as concerns about body components or functions (BUTB). Mediation analysis indicated that BUT-A mediated the relationship between obsessive-compulsive symptoms and BUTB. CONCLUSION: This study offers new insights into the comprehensive landscape of OCRDs. It specifically emphasizes the association between obsessive-compulsive symptoms and body uneasiness, embracing not only concerns about body shape and weight but also extending to body components and functions.

Social cognition in people with schizophrenia: a cluster-analytic approach.

BACKGROUND: The study aimed to subtype patients with schizophrenia on the basis of social cognition (SC), and to identify cut-offs that best discriminate among subtypes in 809 out-patients recruited in the context of the Italian Network for Research on Psychoses. METHOD: A two-step cluster analysis of The Awareness of Social Inference Test (TASIT), the Facial Emotion Identification Test and Mayer-Salovey-Caruso Emotional Intelligence Test scores was performed. Classification and regression tree analysis was used to identify the cut-offs of variables that best discriminated among clusters. RESULTS: We identified three clusters, characterized by unimpaired (42%), impaired (50.4%) and very impaired (7.5%) SC. Three theory-of-mind domains were more important for the cluster definition as compared with emotion perception and emotional intelligence. Patients more able to understand simple sarcasm (⩾14 for TASIT-SS) were very likely to belong to the unimpaired SC cluster. Compared with patients in the impaired SC cluster, those in the very impaired SC cluster performed significantly worse in lie scenes (TASIT-LI <10), but not in simple sarcasm. Moreover, functioning, neurocognition, disorganization and SC had a linear relationship across the three clusters, while positive symptoms were significantly lower in patients with unimpaired SC as compared with patients with impaired and very impaired SC. On the other hand, negative symptoms were highest in patients with impaired levels of SC. CONCLUSIONS: If replicated, the identification of such subtypes in clinical practice may help in tailoring rehabilitation efforts to the person's strengths to gain more benefit to the person.

A systematic review of metabolic side effects related to the use of antipsychotic drugs in dementia.

BACKGROUND: In clinical practice, Second Generation Antipsychotics (SGAs) are often used as first-line treatment for the Behavioral and Psychological Symptoms of Dementia (BPSD) in older adults due to their fewer neurological adverse events and similar effectiveness compared with First Generation Antipsychotics (FGAs). SGAs, however, are associated with more severe metabolic side effects (weight gain, hyperglycemia, diabetes risk, and hyperlipidemia) than FGAs are. In general, older patients, especially those affected by dementia, are at increased risk for malnutrition, and tend to have lower basal metabolism and reduced liver and kidney function. However, little is known about the metabolic side effects of antipsychotic drugs in this population. METHODS: A comprehensive review of the literature published between January 1996 and December 2012 investigating the metabolic side effects related to FGAs and SGAs use in old patients affected by dementia. RESULTS: Antipsychotic drugs currently used to treat BPSD in subjects with mild to moderate dementia are associated with weight gain. Currently, there are insufficient data to support a causal relationship between the use of FGAs and SGAs and changes in glucose homeostasis or lipid metabolism in older persons affected by severe dementia (MMSE <14). CONCLUSION: A possible association between antipsychotic drugs use and weight gain might exist, in particular in subjects with mild to moderate dementia whereas no significant effects are demonstrated regarding glucose homeostasis and lipid metabolism. The antipsychotic drugs potential for causing metabolic abnormalities in older patients requires further specifically designed studies. Clinicians must be aware of this possibility even if the shorter periods of treatment administered in late-life might not be as harmful as it is in younger individuals.

The missing link between philosophy and psychopathology.

INTRODUCTION: The uncertainty regarding the scientific status of psychiatry arises from psychiatry's involvement with some unsolved problems, or put in another way, from its enmeshment in certain points of transition of contemporary science. There is, in primis, the unsolved problem of the relationship between the mind and the body and, moreo- ver, the intricate relationship of connection/disjunction among biology, social science, anthropology, philosophy, etc. To speak about what psychopathology can expect from philosophy is, above all, to immerse oneself in a debate about the conditions of possibility of psychiatry as a science. This debate is especially concerned with the models of knowledge that have, until now, been proposed to psychiatry. Those models oscillate between the Dilthey's paradigms of the "Science of Nature" and the "Science of Spirit". METHODS: It is certain that psychopathology, as already indicated by Jaspers, is a discipline which is among the most involved regard- ing the use of the two different cognitive strategies. The first strategy concerns the concept of "explanation" and its rigid approach to the objective and ultimate cause of the phenomenon. The second strategy is the "comprehensive" approach. This model, which the hermeneutic thought defines "interpretative", theorizes the provisional character, the subjectiveness and the finiteness of every cognitive project. RESULTS: The interest of the authors is orientated towards the hermeneutic side (comprehensive-interpretative) of psychiatry, that which deals with the specificity of every clinical history, with the continuity of sense, and with intrinsic narrative intelligibility of every human event, psychopathological or not. CONCLUSIONS: This approach to psychopathology is based on the statement: "a clinical history is a text which must be interpreted". From this perspective, every clinical history should be perceived as a text to decipher but, above all, as a "text" to listen to, in the persevering expectation that it could disclose its particular "project of world". When speaking about psychiatry, we always face a problem which dominates all the others: the unsolved problem of the relation- ship between typicalness and singularity of subjective events. B.B. Mandelbrot, theorist of "fractals", sums this dilemma up clearly. He suggests that the innumerable variety of the configurations of Nature is a challenge to investigate the morphology of that which is "irregu- lar" in order to discover in it, as far as possible, a rule.

Never too late to be anxious: validation of the Geriatric Anxiety Inventory, Italian version.

AIM: The aim of this work was to validate the Italian version of GAI (GAI-It) and its short form (GAI-It SF) in an over 65-population. METHODS: In 3 recruitment areas across Italy, two raters reciprocally blind to results assessed eligible subjects; a semi-structured diagnostic clinical interview was performed by a psychiatrist. RESULTS: Among the 76 enrolled subjects (mean age 72.7±6.8 years), anxiety symptoms were very common: 69.7% (moderate/ severe HADS-Anxiety), 76.3% (moderate/severe STAI-state), 71.0% (moderate/severe STAI-trait), 61.8% (GAI), 55.3% (GAI-SF). Sensitivity, specificity and positive predictive value of GAI confirmed a good reliability of the Italian version, with Cronbach's Alpha equal to 0.93 for GAI-It and to 0.77 for GAI-It SF, indicating a very good and good construct validity, respectively, of the scales. The Pearson correlation index demonstrated a moderately positive correlation among GAI, GAI-SF and STAI. CONCLUSIONS: Our data confirm the validity of GAI-It as a valuable instrument to assess anxiety in an elderly population, for clinical and research purposes.

Coma After Quetiapine Fumarate Intentional Overdose in a 71-year-old Man: A Case Report.

A 71-year-old man developed coma with severe respiratory failure, hypotension, and tachycardia induced by the intentional ingestion of quetiapine fumarate extended release (XR) 20 g. At the time, he had been treated for bipolar depression with venlafaxine 75 mg/day, lamotrigine 100 mg/day, pregabalin 75 mg/day, and quetiapine XR 400 mg/day for approximately 1 year. Comorbidities were hypertension treated with metoprolol, diabetes mellitus type 2 treated with metformin, and benign prostatic hyperplasia treated with silodosin. In the emergency room, about 4 h after ingestion of quetiapine fumarate XR, the presenting symptomatology was characterized by coma (Glasgow Coma Scale score 3), hypotension (blood pressure [BP] 90/60 mmHg), tachycardia (electrocardiogram [ECG] showed sinus tachycardia with heart rate 120 beats per minute and a QTc of 499 ms). A gastric lavage was performed and activated charcoal 50 g and magnesium sulfate 30 g was administered. About 6 h after ingestion, he developed marked desaturation and underwent mechanical ventilation; 13 h after ingestion, a severe hypotensive episode followed (BP 70/40), which was treated with an infusion of ringer lactate 500 cc. On the 3rd day after intentional overdose, an episode of agitation occurred; 4 days after ingestion, the quetiapine plasma level was found to be 42 ng/ml (within therapeutic range). At 5 days after ingestion, the patient developed septicemia caused by staphylococci (probably originating from the central vein catheter), which was treated with antibiotic therapy. On days 10 and 18 after the suicide attempt, two episodes of paroxysmal supraventricular tachycardia (PSVT) occurred and were successfully treated with intravenous adenosine triphosphate. The patient recovered completely without residual symptoms. In line with literature data, in this case report, symptoms of quetiapine overdose were tachycardia, agitation, hypotension, QT interval prolongation, and coma. A causal relationship between PSVT and quetiapine intoxication seems quite unlikely due to the drug level.

Aging and the occurrence of dementia: findings from a population-based cohort with a large sample of nonagenarians.

CONTEXT: In spite of numerous studies on the occurrence of dementia, many questions remain, such as the relation between age, aging, and dementing disorders. This question is relevant both for understanding the pathogenetic mechanism of the dementias and for the public health prospective because of the increasing number of 85-year-old or older persons in our population. OBJECTIVE: To estimate the occurrence of dementia in the very old, including nonagenarians, in relation to age, gender, and different dementia types. DESIGN: An epidemiological survey where all participants were clinically examined by physicians, assessed by psychologists, and interviewed by nurses. The Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition (DSM-III-R) criteria for dementia were followed. A category of "questionable dementia" was added when all criteria were not fulfilled. A double diagnostic procedure was used for all subjects. SETTING: Community-based population, including all inhabitants of 2 areas in central Stockholm, Sweden (N = 1848). PARTICIPANTS: Of the 1848 subjects in the study population, 168 (9.1%) had died and 56 (3%) moved before examination. Of the remaining subjects, 1424 (87.7%) were examined, and the refusal rate was 12.3%. MAIN OUTCOME MEASURES: Age- and gender-specific prevalence figures, and gender- and education-adjusted odds ratios were used. RESULTS: At the end of the diagnostic procedure, 358 clinically definite cases of dementia and 101 questionable cases of dementia were identified. Alzheimer disease (AD) contributed to 76.5%, and vascular dementia (VaD) to 17.9%. The prevalence of dementia increases from 13% in the 77- to 84-year-old subjects to 48% among persons 95 years and older (from 18% to 61% when questionable cases were included). The odds ratio for subjects 90 to 94 years and 95 years and older in comparison with 77- to 84-year-old subjects was 3.7 (95% confidence interval [CI], 2.7-5.1) and 6.5 (95% CI, 3.9-10.8) for dementia, 4.8 (95% CI, 3.3-7.0) and 8.0 (95% CI, 4.6-14.0) for persons with AD, 2.3 (95% CI, 1.3-4.2) and 4.6 (95% CI, 1.9-11.2) for VaD, respectively. CONCLUSIONS: Dementia prevalence continues to increase even in the most advanced ages. This increase is especially evident among women and is more clear for AD. We believe that our prevalence data reflect the differential distribution of dementia risk.

The effect of education on dementia occurrence in an Italian population with middle to high socioeconomic status.

OBJECTIVE: To explore the relation between education and dementia prevalence by computing the odds ratios (ORs) for different educational levels after adjustment for age, gender, occupational level, and life habits. METHODS: A two-phase community study including 495 elderly subjects with middle to high socioeconomic status, aged more than 60 years and with a high percentage of noneducated subjects, was carried out in the province of Ravenna, Italy. Dementia and dementia type were clinically diagnosed using DSM-III-R diagnostic criteria. RESULTS: A higher prevalence of dementia was observed among noneducated subjects of both genders. Comparing no education with any education, the OR (adjusted for age, gender, and occupation) was 4.7 (95% CI = 2.3 to 9.6). The association, although present in all age groups, was extraordinarily strong among the youngest subjects (61 to 69 years) (OR = 139.5, 95% CI = 6.4 to 3,024.6) and decreased with increasing age. Life habits, such as smoking and alcohol consumption as well as current or previous history of hypertension, did not change the results. There was no significant difference in dementia prevalence among less well-educated (up to 3 years of education) and better-educated subjects (more than 3 years of schooling) after age and gender were taken into account. Similar findings were found for Alzheimer's disease and vascular dementia separately. CONCLUSIONS: Having no education is associated with dementia independent of gender, occupation, life habits, and hypertension. This association was stronger among younger old persons, and decreased with increasing age. The findings suggest that the first decade of life is a critical period for developing dementia later in life. The decrease in dementia risk may be due to schooling, according to the cerebral reserve hypothesis, or to other factors associated with a higher educational level during childhood.

Prevalence and severity of dementia among northern Italian centenarians.

Using diagnostic criteria from the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders, dementia was clinically diagnosed in 57 (62%) of 92 centenarians living in two northern Italian provinces. The condition was severely disabling in approximately 70% of the demented patients. Although clinically diagnosed AD accounted for 79% of dementia cases, almost one third of patients with AD had risk factors for vascular dementia, suggesting that the aging brain may be susceptible to multiple additive factors that impair cognition.

Worldwide prevalence and incidence of dementia.

Dementia is a common and disabling disorder in the elderly. Because of the worldwide aging phenomenon, existing in both developed and developing countries, dementia has a growing public health relevance. This article reviews the prevalence and incidence data for dementia reported in the international literature in the last 10 years. Results from 36 prevalence and 15 incidence studies have been examined. Prevalence is equal to 0.3 to 1.0 per 100 people in individuals aged 60 to 64 years, and increases to 42.3 to 68.3 per 100 people in individuals 95 years and older. The incidence varies from 0.8 to 4.0 per 1,000 person years in people aged 60 to 64 years, and increases to 49.8 to 135.7 per 1,000 person years when the population was older than 95 years. The international comparison allows the following conclusions: (i) both prevalence and incidence show little geographical variation, as differences between countries seem to reflect methodological rather than real differences [the low prevalence of dementia in Africa needs to be confirmed by incidence data]; (ii) both incidence and prevalence figures increase with age even in the advanced ages; (iii) regarding dementia types, most of the inconsistency in results from different studies is due to vascular dementia rather than to Alzheimer's disease (AD); (iv) it is still unclear if the reported higher frequency of vascular dementia in Asian populations is due to differential distribution of genetic and/or environmental factors, or due to methodological differences; (v) different dementia types might have different age distributions.

Analytical methods for the quality control of Prozac capsules.

Some analytical methods (two spectrophotometric and two chromatographic procedures) for the determination of fluoxetine in Prozac capsules are described. All of them are applied to the samples after extracting the drug with a methanol water mixture. The direct and derivative spectrophotometric methods are simple and reliable; the derivative method gives better recovery and lessens interference. Both methods show linearity in the 5-30 microg ml(-1) range of the fluoxetine concentration range. Both HPLC methods (spectrophotometric and spectrofluorimetric detection) use a tetramethylammonium perchlorate buffer-acetonitrile mixture as the mobile phase and a C8 reversed phase column. The UV detection is performed at 226 nm, while the fluorimetric detection is performed by exciting at 230 nm and revealing the emission at 290 nm. The HPLC method with UV detection is more precise, but the procedure with fluorimetric detection is more sensitive.

Animal-assisted interventions for elderly patients affected by dementia or psychiatric disorders: a review.

OBJECTIVE: The aim of this literature review was to assess the effects of Animal-Assisted Interventions (AAI) on elderly patients with dementia or various psychiatric disorders. METHODS: We conducted a comprehensive literature search using the online PubMed network of the US National Library of Medicine & National Institutes of Health, Embase, PsycINFO, with the purpose of investigating AAI effects on cognitive functions, mood, and behaviour. RESULTS: A total of 18 articles on dementia and 5 on psychiatric disorders were included in the present review. AAI were found to have positive influences on demented patients by reducing degree of agitation and by improving degree and quality of social interaction. Few studies have assessed the effects of AAI on mood, and even fewer have assessed its consequences on cognitive functions. The results that are available indicate a positive effect on communication and coping ability, but none on cognitive performance. A substitute pet robot yielded encouraging results, but its use requires further investigation. The few studies conducted for elderly patients presenting a variety of psychiatric diagnoses produced controversial findings. CONCLUSIONS: In spite of the encouraging results of AAI, much more research examining the issue of optimal AAI duration, frequency of sessions, and suitable target group is needed.

Meta-analysis of serotonin transporter gene promoter polymorphism (5-HTTLPR) association with selective serotonin reuptake inhibitor efficacy in depressed patients.

The serotonin transporter gene promoter polymorphism (5-HTTLPR) has been repeatedly associated with antidepressant response in mood disorder patients, but findings are not consistent across studies. A meta-analysis was performed on 15 studies including data of 1435 subjects. We tested three phenotypes: remission rate, response rate and response rate within 4 weeks using the cochrane review manager. We observed a significant association of the s/s variant of 5-HTTLPR with remission rate (P<0.0001) and both s/s and s/l variants with response rate (P=0.0002). Response rate within 4 weeks was associated in both models (P=0.003-P<0.00001). This effect is quite robust to ethnic differences although a significant heterogeneity is present in Asian samples.

Psychopathology of first-episode psychosis in HIV-positive persons in comparison to first-episode schizophrenia: a neglected issue.

This study aims to detect different psychopathological dimensions in first-episode psychoses with different underlying causes. We evaluated 22 subjects with first-episode psychosis, who differed in biological variables (HIV-positive versus HIV-negative) and who were compared by using the Structured Clinical Interview for DSM-III-Reviewer, the 18-item Brief Psychiatric Rating Scale (BPRS), the 17-item Hamilton Depression Rating Scale, the 14-item Hamilton Anxiety Rating Scale and the Mini-Mental State Examination. HIV-positive subjects had higher mean scores on the global BPRS and on the paranoid Positive and Negative Syndrome Scale subscale compared with HIV-negative subjects. Conversely, higher prevalence of affective and anxious symptoms was found in the HIV-negative patients in comparison to HIV-positives. HIV-positives had significantly greater attention/concentration impairment than HIV-negative persons. In conclusion, taking into account psychopathological dimensions may help psychiatrists in clinical decision-making regarding the differential diagnosis of psychotic symptoms. The psychopathological pattern of first-episode psychosis in HIV-positive patients may represent an 'elementary model' of acute psychosis characterized by paranoid delusions in the absence of the usual affective symptoms.

Personality disorders and depressive symptoms in late luteal phase dysphoric disorder.

BACKGROUND: Although many significant studies of late luteal phase dysphoric disorder (LLPD) have been carried out, some conflicting findings on the relationships between personality disorders, depressive symptoms, hostility and LLPD deserve further investigation. METHODS: Forty-three LLPD patients and 85 control subjects, evaluated by prospective daily ratings during two symptomatic cycles, received a detailed psychiatric evaluation, including the sections for psychotic, affective and anxiety disorders of the Structured Clinical Interview for DSM-III-R nonpatient version and the section for personality disorders; the Buss Durkee Inventory for Assessing Different Kinds of Hostility and the Montgomery-Asberg Depression Rating Scale. RESULTS: The odds of suffering from LLPD are about nine-fold (crude odds ratio, OR = 9.23, 95% confidence interval, CI 3.98-21.39) among women with mild or moderate depressive symptoms. When two age strata (below and above 30) are analyzed separately, the association between LLPD and depressive symptoms is strong and positive in both strata, while the association between LLPD and avoidant personality disorder is found only among older women (adjusted OR = 8.26, p < 0.05, 95% CI 1.03-66.35). CONCLUSIONS: The major finding from this preliminary study is the association between LLPD and depressive symptoms. Conversely, the association between LLPD and avoidant personality disorder remains controversial and seems to be dependent on age. Our findings support the hypothesis that LLPD and avoidant personality disorder may be considered as part of the spectrum of recurrent mood disorder rather than as qualitatively distinct nosological entities. Future studies are needed, adopting prospective, longitudinal assessments of personality prior to the onset of LLPD.

Development of acute psychotic disorders and HIV-1 infection.

OBJECTIVE: To gain more understanding about the relationship between human immunodeficiency virus type 1 (HIV-1) infection and new-onset psychosis, we compared clinical and immunological findings, psychiatric symptoms, global cognitive performance and, when available, computerized tomography (CT) findings between HIV-1-seropositive patients with new-onset psychosis and well-matched nonpsychotic HIV-1-seropositives. METHODS: Two groups of subjects: HIV-1-seropositives with new-onset psychosis (n = 12) and HIV-1-seropositives without psychosis (n = 15) were recruited through outpatient departments. Organic Delusional Syndrome and Organic Hallucinosis were clinically diagnosed using DSM-III-R diagnostic criteria. Of the baseline participants, twenty-two participated in the two-year follow-up examination. RESULTS: The prevalence of new-onset psychosis in HIV-1-infected subjects was 3.7 per 100 (95% C.I. = 1.6-5.7). HIV-1-seropositive persons with new-onset psychosis had more frequently a positive past psychiatric history, no antiretroviral therapy, and a lower global cognitive performance than did the nonpsychotic HIV-1-seropositives. CT was positive, showing generalized brain atrophy, in three out of nine patients. Remission of psychotic symptoms was observed only in two HIV-1-seropositive persons with new-onset psychosis. Death occurred in two psychic HIV-1-seropositives with simple loosely held delusions. Autopsy results showed that cortical sulci and ventricle size were graded as with moderate/severe enlargement. CONCLUSIONS: New-onset psychosis in HIV infected patients could raise considerable problems in deciding whether a presentation is organic or functional. An interaction of the disease or of psychologically "having" the disease with the presence of a psychotic reaction should also be considered. Interestingly, a protective effect of antiretroviral therapy for new-onset psychosis is suggested.
