RESUMO

Geographic tongue (GT), a form of inverse psoriasis, is frequently linked to plaque psoriasis. The objective of the study is to evaluate IL-17 blocker (secukinumab) effect on GT severity. This reallife, multicenter, retrospective observational pilot study evaluated patients with plaque psoriasis and concomitant GT that started in label treatment with secukinumab. Patients were evaluated twice (T0=baseline and T1=after 16 weeks) by a dentist and a dermatologist collecting data on cutaneous Psoriasis Area Severity Index (PASI) and oral statuses using Hume's classification of the Geographic Tongue Severity Index (GTASI). Twenty-nine psoriatic patients with GT treated with secukinumab were enrolled for the study. Seventeen patients display type I GT, 6 type II and 6 type III with an overall GTASI of 25.52±9.57 at the baseline (T0). No correlation was found between delta GTASI and delta PASI (r=-0.27, p=0.1551). GTASI decrement from T0 to T1 was statistically significant ([95%CI -26.64 to -19.56], t=-13.36, p<0.0001). Secukinumab may enter in GT therapeutic armamentarium as the first biologic IL-17 blocker in patients with concomitant moderate-to-severe plaque psoriasis.

RESUMO

Geographic tongue (GT) represents a localized type of psoriasis inversa and its burden of dermatological and oral comorbidities frequently conditions its severity and diagnosis. Currently, no epidemiological studies have evaluated GT muco-cutaneous comorbidities. We aimed to study oral and dermatological comorbidities in a large sample of GT patients. In this multicenter, cross-sectional study, involving 4 primary referral centers in Italy, we evaluated adult GT patients, who were assessed by board certified dermatologists and dentists for 5 months and collected demographics and medical history. GT was evaluated using Hume's classification together with Geographic tongue severity index (GTASI) to score its severity. The prevalence of oral and dermatological comorbidities was recorded. In the sample we enrolled 137 GT patients (M/F= 5:1) with a mean age of 48,2 ± 14,7 yoa and 33.6% had GT family history. The clinical evaluation found 96 (70.1%) GT type I, 7 (5.1%) type II, 13 (9.5%) type IIIa, 19 (13.9%) type IIIb, 2 (1.5%) type IV, following Hume's classification. The mean GTASI score was 23,7 ± 14,2 and the vast majority displayed a severe form of GT. Eighty-nine patients had oral comorbidities (burning mouth syndrome, caries, parulid and lichen planus) and 80 had dermatological concurrent conditions (plaque psoriasis, inverse psoriasis and atopic dermatitis). In GT patients, both dermatological and dental evaluation should be mandatory to identify previously undiagnosed mucocutaneous comorbidities.

RESUMO

OBJECTIVE: To quantify the risk of hip fracture, thromboembolism, stroke, myocardial infarction, pneumonia and sudden cardiac death associated with exposure to antipsychotics. METHODS: Systematic searches were conducted in Medline, Embase and PsycINFO from inception until 30/07/2018 for systematic reviews of observational studies. AMSTAR-2 was used for the quality assessment of systematic reviews, while the strength of associations was measured using GRADE and quantitative umbrella review criteria (URC). RESULTS: Sixty-eight observational studies from six systematic reviews were included. The association between antipsychotic exposure and pneumonia was the strongest [URC = class I; GRADE = low quality; odds ratio (OR) = 1.84, 95% confidence interval (CI) = 1.62-2.09; participants = 28 726; age = 76.2 ± 12.3 years], followed by the association with hip fracture (URC = class II; GRADE = low quality; OR = 1.57, 95% CI = 1.42-1.74; participants = 5 288 118; age = 55.4 ± 12.5 years), and thromboembolism (URC = class II; GRADE = very low quality; OR = 1.55, 95% CI = 1.31-1.83; participants = 31 417 175; age = 55.5 ± 3.2 years). The association was weak for stroke (URC = class III; GRADE = very low quality; OR = 1.45, 95% CI = 1.24-1.70; participants = 65 700; age = 68.7 ± 13.8 years), sudden cardiac death (URC = class III; GRADE = very low quality; OR = 2.24, 95% CI = 1.45-3.46; participants = 77 488; age = 52.2 ± 6.2 years) and myocardial infarction (URC = class III; GRADE = very low quality; OR = 2.21, 95% CI = 1.41-3.46; participants = 399 868; age = 74.1 ± 9.3 years). CONCLUSION: The most robust results were found for the risk of pneumonia, followed by the risk of hip fracture and thromboembolism. For stroke, sudden cardiac death and myocardial infarction, the strength of association was weak. The observational nature of the primary studies may represent a source of bias.

RESUMO

BACKGROUND: Impairments in the attribution of salience are thought to be fundamental to the development of psychotic symptoms and the onset of psychotic disorders. The aim of the present study was to explore longitudinal alterations in salience processing in ultra-high-risk subjects for psychosis. METHOD: A total of 23 ultra-high-risk subjects and 13 healthy controls underwent functional magnetic resonance imaging at two time points (mean interval of 17 months) while performing the Salience Attribution Test to assess neural responses to task-relevant (adaptive salience) and task-irrelevant (aberrant salience) stimulus features. RESULTS: At presentation, high-risk subjects were less likely than controls to attribute salience to relevant features, and more likely to attribute salience to irrelevant stimulus features. These behavioural differences were no longer evident at follow-up. When attributing salience to relevant cue features, ultra-high-risk subjects showed less activation than controls in the ventral striatum at both baseline and follow-up. Within the high-risk sample, amelioration of abnormal beliefs over the follow-up period was correlated with an increase in right ventral striatum activation during the attribution of salience to relevant cue features. CONCLUSIONS: These findings confirm that salience processing is perturbed in ultra-high-risk subjects for psychosis, that this is linked to alterations in ventral striatum function, and that clinical outcomes are related to longitudinal changes in ventral striatum function during salience processing.

RESUMO

OBJECTIVE: Since the first study published in the Lancet in 1976, structural neuroimaging has been used in psychosis with the promise of imminent clinical utility. The actual impact of structural neuroimaging in psychosis is still unclear. METHOD: We present here a critical review of studies involving structural magnetic resonance imaging techniques in patients with psychosis published between 1976 and 2015 in selected journals of relevance for the field. For each study, we extracted summary descriptive variables. Additionally, we qualitatively described the main structural findings of each article in summary notes and we employed a biomarker rating system based on quality of evidence (scored 1-4) and effect size (scored 1-4). RESULTS: Eighty studies meeting the inclusion criteria were retrieved. The number of studies increased over time, reflecting an increased structural imaging research in psychosis. However, quality of evidence was generally impaired by small samples and unclear biomarker definitions. In particular, there was little attempt of replication of previous findings. The effect sizes ranged from small to modest. No diagnostic or prognostic biomarker for clinical use was identified. CONCLUSIONS: Structural neuroimaging in psychosis research has not yet delivered on the clinical applications that were envisioned.

RESUMO

OBJECTIVE: About one-third of patients referred to services for people at high risk for psychosis may have already developed a first episode of psychosis (FEP). We compared clinical outcomes in FEP patients who presented to either high risk or conventional mental health services. METHOD: Retrospective study comparing duration of hospital admission, referral-to-diagnosis time, need for compulsory hospital admission and frequency of admission in patients with FEP who initially presented to a high-risk service (n = 164) to patients with FEP who initially presented to conventional mental health services (n = 2779). Regression models were performed, controlling for several confounders. RESULTS: FEP patients who had presented to a high-risk service spent 17 fewer days in hospital [95% CI: -33.7 to (-0.3)], had a shorter referral-to-diagnosis time [B coefficient -74.5 days, 95% CI: -101.9 to -(47.1)], a lower frequency of admission [IRR: 0.49 (95% CI: 0.39-0.61)] and a lower likelihood of compulsory admission [OR: 0.52 (95% CI: 0.34-0.81)] in the 24 months following referral, as compared to FEP patients who were first diagnosed at conventional services. CONCLUSION: Services for people at high risk for psychosis are associated with better clinical outcomes in patients who are already psychotic.

RESUMO

The past 20 years have seen the evolution of the construct of a clinical high-risk (hereafter, HR) state for psychosis. This construct is designed to capture the pre-psychotic phase. Some aspects of this approach, such as its feasibility in children and adolescents, are still under investigation. In the present study, we address the feasibility of implementing prodrome clinics for HR individuals within the framework of Italy's national child and adolescent neuropsychiatry services and the clinical relevance of a HR diagnosis in this population. Using the Comprehensive Assessment of At-Risk Mental States (CAARMS) to identify help-seeking patients meeting at least one HR criterion at baseline (HR+), we recruited 50 subjects for a feasibility study. The results obtained show that the Italian version of the CAARMS is easily administrable, causing patients no substantial discomfort. The prevalence of HR+ in our cohort was 44 %, which increased by an additional 18 % when negative symptoms were considered as an experimental inclusion criterion (HRNeg). The HR+ subjects were significantly more impaired in their social and occupational functioning than their HR- peers (subjects not at HR). The cumulative 1-year transition risk of psychosis of the HR+ group was 26.7 %. When the HRNeg group was added, the 1-year transition risk was 17.3 %. We suggest that administration of the CAARMS to children and adolescents with putative prodromal psychosis is feasible and that this assessment can easily be integrated into existing Italian neuropsychiatry services although clinicians should interpret results with caution as results in this age group still have to be replicated.

RESUMO

BACKGROUND: Recent randomized controlled trials suggest some efficacy for focused interventions in subjects at high risk (HR) for psychosis. However, treating HR subjects within the real-world setting of prodromal services is hindered by several practical problems that can significantly make an impact on the effect of focused interventions. METHOD: All subjects referred to Outreach and Support in South London (OASIS) and diagnosed with a HR state in the period 2001-2012 were included (n = 258). Exposure to focused interventions was correlated with sociodemographic and clinical characteristics at baseline. Their association with longitudinal clinical and functional outcomes was addressed at follow-up. RESULTS: In a mean follow-up time of 6 years (s.d. = 2.5 years) a transition risk of 18% was observed. Of the sample, 33% were treated with cognitive behavioural therapy (CBT) only; 17% of subjects received antipsychotics (APs) in addition to CBT sessions. Another 17% of subjects were prescribed with antidepressants (ADs) in addition to CBT. Of the sample, 20% were exposed to a combination of interventions. Focused interventions had a significant relationship with transition to psychosis. The CBT + AD intervention was associated with a reduced risk of transition to psychosis, as compared with the CBT + AP intervention (hazards ratio = 0.129, 95% confidence interval 0.030-0.565, p = 0.007). CONCLUSIONS: There were differential associations with transition outcome for AD v. AP interventions in addition to CBT in HR subjects. These effects were not secondary to baseline differences in symptom severity.

RESUMO

BACKGROUND: The past two decades have seen exponential clinical and research interest in help-seeking individuals presenting with potentially prodromal symptoms for psychosis. However, the epidemiological validity of this paradigm has been neglected, limiting future advancements in the field. METHOD: We undertook a critical review of core epidemiological issues underlying the clinical high-risk (HR) state for psychosis and which model of prodromal intervention is best suited for mental health. RESULTS: The HR state for psychosis model needs refining, to bring together population-based findings of high levels of psychotic experiences (PEs) and clinical expression of risk. Traditionally, outcome has been attributed to 'HR criteria' alone rather than taking into account sampling strategies. Furthermore, the exclusive focus on variably defined 'transition' obscures true variation in the slow and non-linear progression across stages of psychopathology. Finally, the outcome from HR states is variable, indicating that the underlying paradigm of 'schizophrenia light progressing to schizophrenia' is inadequate. CONCLUSIONS: In the general population, mixed and non-specific expression of psychosis, depression, anxiety and subthreshold mania is common and mostly transitory. When combined with distress, it may be considered as the first, diagnostically neutral stage of potentially more severe psychopathology, which only later may acquire a degree of diagnostic specificity and possible relative resistance to treatment. Therefore, rather than creating silos of per-disorder ultra-HR syndromes, an early intervention focus on the broad syndrome of early mental distress, requiring phase-specific interventions, may be more profitable.

RESUMO

BACKGROUND: The majority of people at ultra high risk (UHR) of psychosis also present with co-morbid affective disorders such as depression or anxiety. The neuroanatomical and clinical impact of UHR co-morbidity is unknown. METHOD: We investigated group differences in grey matter volume using baseline magnetic resonance images from 121 participants in four groups: UHR with depressive or anxiety co-morbidity; UHR alone; major depressive disorder; and healthy controls. The impact of grey matter volume on baseline and longitudinal clinical/functional data was assessed with regression analyses. RESULTS: The UHR-co-morbidity group had lower grey matter volume in the anterior cingulate cortex than the UHR-alone group, with an intermediate effect between controls and patients with major depressive disorder. In the UHR-co-morbidity group, baseline anterior cingulate volume was negatively correlated with baseline suicidality/self-harm and obsessive-compulsive disorder symptoms. CONCLUSIONS: Co-morbid depression and anxiety disorders contributed distinctive grey matter volume reductions of the anterior cingulate cortex in people at UHR of psychosis. These volumetric deficits were correlated with baseline measures of depression and anxiety, suggesting that co-morbid depressive and anxiety diagnoses should be carefully considered in future clinical and imaging studies of the psychosis high-risk state.

RESUMO

BACKGROUND: Cannabis use is associated with an increased risk of developing a psychotic disorder but the temporal relationship between cannabis use and onset of illness is unclear. The objective of this study was to assess prospectively the influence of cannabis use on transition to psychosis in people at ultra-high risk (UHR) for the disorder. METHOD: Lifetime and continued cannabis use was assessed in a consecutively ascertained sample of 182 people (104 male, 78 female) at UHR for psychosis. Individuals were then followed clinically for 2 years to determine their clinical outcomes. RESULTS: Lifetime cannabis use was reported by 134 individuals (73.6%). However, most of these individuals had stopped using cannabis before clinical presentation (n=98, 73.1%), usually because of adverse effects. Among lifetime users, frequent use, early-onset use and continued use after presentation were all associated with an increase in transition to psychosis. Transition to psychosis was highest among those who started using cannabis before the age of 15 years and went on to use frequently (frequent early-onset use: 25%; infrequent or late-onset use: 5%; χ(2)1=10.971, p=0.001). However, within the whole sample, cannabis users were no more likely to develop psychosis than those who had never used cannabis (cannabis use: 12.7%; no use: 18.8%; χ(2)1=1.061, p=0.303). CONCLUSIONS: In people at UHR for psychosis, lifetime cannabis use was common but not related to outcome. Among cannabis users, frequent use, early-onset use and continued use after clinical presentation were associated with transition to psychosis.

RESUMO

Prodromal features of the schizophrenia syndrome have been described for a century, and work in the past two decades has produced a substantial literature based on these features to identify individuals at increased risk for developing a psychotic disorder. Sometimes conceptualized as a "risk state" and sometimes as early manifestations of a "disorder," the work has been conducted with several related but different constructs. Early in the preparation of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) public comment was sought on the proposal to create a new disorder termed attenuated psychosis syndrome (APS), and a range of issues emerged that generated interesting and important controversies. In this review, these criticisms are fully discussed, the APS concept is explicated; data relating to reliability, validity, and treatment are updated; the heterogeneity of APS is considered; and alternative views of the construct are presented with an emphasis on developmental pattern with timing for primary and secondary prevention and early treatment. Areas of future research are identified, and a potential roadmap for inclusion in DSM-5.1 is traced.

RESUMO

BACKGROUND: Many research groups have attempted to predict which individuals with an at-risk mental state (ARMS) for psychosis will later develop a psychotic disorder. However, it is difficult to predict the course and outcome based on individual symptoms scores. METHOD: Data from 318 ARMS individuals from two specialized services for ARMS subjects were analysed using latent class cluster analysis (LCCA). The score on the Comprehensive Assessment of At-Risk Mental States (CAARMS) was used to explore the number, size and symptom profiles of latent classes. RESULTS: LCCA produced four high-risk classes, censored after 2 years of follow-up: class 1 (mild) had the lowest transition risk (4.9%). Subjects in this group had the lowest scores on all the CAARMS items, they were younger, more likely to be students and had the highest Global Assessment of Functioning (GAF) score. Subjects in class 2 (moderate) had a transition risk of 10.9%, scored moderately on all CAARMS items and were more likely to be in employment. Those in class 3 (moderate-severe) had a transition risk of 11.4% and scored moderately severe on the CAARMS. Subjects in class 4 (severe) had the highest transition risk (41.2%), they scored highest on the CAARMS, had the lowest GAF score and were more likely to be unemployed. Overall, class 4 was best distinguished from the other classes on the alogia, avolition/apathy, anhedonia, social isolation and impaired role functioning. CONCLUSIONS: The different classes of symptoms were associated with significant differences in the risk of transition at 2 years of follow-up. Symptomatic clustering predicts prognosis better than individual symptoms.

RESUMO

BACKGROUND: Cannabis can induce transient psychotic symptoms, but not all users experience these adverse effects. We compared the neural response to Δ9-tetrahydrocannabinol (THC) in healthy volunteers in whom the drug did or did not induce acute psychotic symptoms. Method In a double-blind, placebo-controlled, pseudorandomized design, 21 healthy men with minimal experience of cannabis were given either 10 mg THC or placebo, orally. Behavioural and functional magnetic resonance imaging measures were then recorded whilst they performed a go/no-go task. RESULTS: The sample was subdivided on the basis of the Positive and Negative Syndrome Scale positive score following administration of THC into transiently psychotic (TP; n = 11) and non-psychotic (NP; n = 10) groups. During the THC condition, TP subjects made more frequent inhibition errors than the NP group and showed differential activation relative to the NP group in the left parahippocampal gyrus, the left and right middle temporal gyri and in the right cerebellum. In these regions, THC had opposite effects on activation relative to placebo in the two groups. The TP group also showed less activation than the NP group in the right middle temporal gyrus and cerebellum, independent of the effects of THC. CONCLUSIONS: In this first demonstration of inter-subject variability in sensitivity to the psychotogenic effects of THC, we found that the presence of acute psychotic symptoms was associated with a differential effect of THC on activation in the ventral and medial temporal cortex and cerebellum, suggesting that these regions mediate the effects of the drug on psychotic symptoms.

RESUMO

In general population about 15-20% of subjects have suffered from one episode of urticaria-angioedema syndrome in their life. The etiology of his condition is various and multifactorial. In children the principal cause of acute urticaria is infection, while physical factors are the main agents of chronic urticaria. All those conditions which lack an etiology are named chronic idiopathic urticaria, but in reality a considerable number of these patients is affected by a chronic autoimmune urticaria. For this reason, screening out the most frequent causes of chronic urticaria, it's useful to know when it's possible to apply specific diagnostic tests for this condition and which therapies are employable.

RESUMO

BACKGROUND: Although individuals vulnerable to psychosis show brain volumetric abnormalities, structural alterations underlying different probabilities for later transition are unknown. The present study addresses this issue by means of voxel-based morphometry (VBM). METHOD: We investigated grey matter volume (GMV) abnormalities by comparing four neuroleptic-free groups: individuals with first episode of psychosis (FEP) and with at-risk mental state (ARMS), with either long-term (ARMS-LT) or short-term ARMS (ARMS-ST), compared to the healthy control (HC) group. Using three-dimensional (3D) magnetic resonance imaging (MRI), we examined 16 FEP, 31 ARMS, clinically followed up for on average 3 months (ARMS-ST, n=18) and 4.5 years (ARMS-LT, n=13), and 19 HC. RESULTS: The ARMS-ST group showed less GMV in the right and left insula compared to the ARMS-LT (Cohen's d 1.67) and FEP groups (Cohen's d 1.81) respectively. These GMV differences were correlated positively with global functioning in the whole ARMS group. Insular alterations were associated with negative symptomatology in the whole ARMS group, and also with hallucinations in the ARMS-ST and ARMS-LT subgroups. We found a significant effect of previous antipsychotic medication use on GMV abnormalities in the FEP group. CONCLUSIONS: GMV abnormalities in subjects at high clinical risk for psychosis are associated with negative and positive psychotic symptoms, and global functioning. Alterations in the right insula are associated with a higher risk for transition to psychosis, and thus may be related to different transition probabilities.

RESUMO

BACKGROUND: Interpersonal sensitivity is a personality trait described as excessive awareness of both the behaviour and feelings of others. Although interpersonal sensitivity has been found to be one of the vulnerability factors to depression, there has been little interest in its relationship with the prodromal phase of psychosis. The aims of this study were to examine the level of interpersonal sensitivity in a sample of individuals with an at-risk mental state (ARMS) for psychosis and its relationship with other psychopathological features. METHOD: Sixty-two individuals with an ARMS for psychosis and 39 control participants completed a series of self-report questionnaires, including the Interpersonal Sensitivity Measure (IPSM), the Prodromal Questionnaire (PQ), the Ways of Coping Questionnaire (WCQ) and the Depression and Anxiety Stress Scale (DASS). RESULTS: Individuals with an ARMS reported higher interpersonal sensitivity compared to controls. Associations between interpersonal sensitivity, positive psychotic symptoms (i.e. paranoid ideation), avoidant coping and symptoms of depression, anxiety and stress were also found. CONCLUSIONS: This study suggests that being 'hypersensitive' to interpersonal interactions is a psychological feature of the putatively prodromal phase of psychosis. The relationship between interpersonal sensitivity, attenuated positive psychotic symptoms, avoidant coping and negative emotional states may contribute to long-term deficits in social functioning. We illustrate the importance, when assessing a young client with a possible ARMS, of examining more subtle and subjective symptoms in addition to attenuated positive symptoms.

RESUMO

Schizophrenia is characterized by altered prefrontal activity and elevated striatal dopaminergic function. To investigate the relationship between these abnormalities in the prodromal phase of the illness, we combined functional Magnetic Resonance Imaging and (18)F-Dopa Positron Emission Tomography. When performing a verbal fluency task, subjects with an At-Risk Mental State showed greater activation in the inferior frontal cortex than controls. Striatal dopamine function was greater in the At-Risk group than in controls. Within the At-Risk group, but not the control group, there was a direct correlation between the degree of left inferior frontal activation and the level of striatal dopamine function. Altered prefrontal activation in subjects with an At-Risk Mental State for psychosis is related to elevated striatal dopamine function. These changes reflect an increased vulnerability to psychosis and predate the first episode of frank psychosis.

RESUMO

Solitary bone cyst (SBC) is an intraosseus radiolucent lesions that defers from real cysts for the fact that peripheral epithelial lining is totally absent. It could be classified as a psudocyst and occurs most frequently in young patients. In most cases SBC doesn't cause symptoms and it is often diagnosed accidentally during routine radiographic examination. A right diagnosis of this disease is also complicated because there are no pathognomonic radiographic signs and symptoms: so this form of pseudocyst is often misdiagnosed as a common odontogenic cyst. Despite numerous studies, the pathogenesis of the SBC is not yet established: the most widely accepted theory is that it could be the result of an intramedullary necrosis determined by a trauma. In this article we report a case of SBC in child treated with a minimal surgical approach. This new kind of treatment is much more conservative than the traditional one, it can be performed as outpatients, under local anesthesia and with few postoperative discomfort: For these reasons this minimal invasive technique appears to be particulary suitable for pediatric patients.
