Purpura of the face and neck: an atypical clinical presentation revealing a hepatosplenic T cell lymphoma

BACKGROUND: Hepatosplenic T cell lymphoma (HSTL) is a rare but very aggressive peripheral T cell lymphoma whose initial silent clinical presentation unfortunately delays the diagnosis and worsens the prognosis of patient survival. Efforts should be aimed at early recognition and treatment. METHODS: We describe a case of a 62-year-old woman who presented at our clinic with a non-palpable purpuric eruption of the face. Investigations revealed thrombocytopenia with hepatosplenomegaly, which showed rapid progression together with accentuation of the purpura. Two months later, a bone marrow biopsy revealed the diagnosis of a HSTL. RESULTS: The patient received six cycles of CHOP chemotherapy (vincristine, cyclophosphamide, doxorubicin, methylprednisolone) followed by a well-tolerated autologous bone marrow graft. Normalization of the platelet count resulted in regression of the purpuric rash. CONCLUSION: To our knowledge, this is the first report of a facial thrombocytopenic purpura as the inaugural symptom of HSTL. It emphasizes the privileged position of the dermatologist for early recognition of potentially lethal HSTL.

Sustained antipsychotic effect of metacognitive training in psychosis: a randomized-controlled study.

Persistent psychotic symptoms represent a major challenge for psychiatric care. Basic research has shown that psychotic symptoms are associated with cognitive biases. Metacognitive training (MCT) aims at helping patients to become aware of these biases and to improve problem-solving. Fifty-two participants fulfilling diagnostic criteria of schizophrenia or schizoaffective disorders and persistent delusions and stabilized antipsychotic medication were enrolled in this study. Following baseline assessment patients were randomized either to treatment as usual (TAU) conditions or TAU+MCT. The intervention consisted of eight weekly 1-hour sessions (maximum: 8 hours). Participants were assessed at 8 weeks and 6-months later by blind assessors. Participants were assessed with the Psychotic Symptoms Rating Scales (PSYRATS) and the positive subscale of the PANSS. Between-group differences in post- and pre-test values were significant at a medium effect size in favor of the MCT for the PSYRATS delusion scale and the positive scale of the PANSS both at post and follow-up. The results of this study indicate that MCT training has a surplus antipsychotic effect for patients suffering from schizophrenia-related disorders who demonstrate only a partial response to antipsychotic treatment and that the effect of the intervention persists for at least 6 months after the intervention.

Two high throughput technologies to detect segmental aneuploidies identify new Williams-Beuren syndrome patients with atypical deletions.

OBJECTIVE: To develop and compare two new technologies for diagnosing a contiguous gene syndrome, the Williams-Beuren syndrome (WBS). METHODS: The first proposed method, named paralogous sequence quantification (PSQ), is based on the use of paralogous sequences located on different chromosomes and quantification of specific mismatches present at these loci using pyrosequencing technology. The second exploits quantitative real time polymerase chain reaction (QPCR) to assess the relative quantity of an analysed locus. RESULTS: A correct and unambiguous diagnosis was obtained for 100% of the analysed samples with either technique (n = 165 and n = 155, respectively). These methods allowed the identification of two patients with atypical deletions in a cohort of 182 WBS patients. Both patients presented with mild facial anomalies, mild mental retardation with impaired visuospatial cognition, supravalvar aortic stenosis, and normal growth indices. These observations are consistent with the involvement of GTF2IRD1 or GTF2I in some of the WBS facial features. CONCLUSIONS: Both PSQ and QPCR are robust, easy to interpret, and simple to set up. They represent a competitive alternative for the diagnosis of segmental aneuploidies in clinical laboratories. They have advantages over fluorescence in situ hybridisation or microsatellites/SNP genotyping for detecting short segmental aneuploidies as the former is costly and labour intensive while the latter depends on the informativeness of the polymorphisms.

Prise en soins de la schizophrénie chez la personne âgée

Care of the elderly schizophrenic patient : Despite the development of new aetiopathological models the treatment of late-life schizophrenia is still based essentially on antipsychotic medication. The absence of research specifically targeting late-life schizophrenics limits the value of recommendations on indication, dosage and treatment alternatives, particularly as the latter have scant regard for the age of schizophrenia onset (early, late, very late onset), for the various comorbidities and the polymedication so common in the elderly. The use of atypical neuroleptics at adapted doses should be combined with biopsychosocial care and treatment of psychiatric and somatic comorbidities. The choice of an adapted treatment is often conditioned, especially if early schizophrenia is con sidered, by many years of treatment and side effects which may limit compliance when the evolution itself has been unfavourable with persistent, sometimes handi capping residual symptoms. Moreover, schizophrenia is complicated by cognitive disorders for which the best therapeutic approach in the elderly remains uncertain.

Prevalence, predictors, and consequences of long-term refusal of antipsychotic treatment in first-episode psychosis.

OBJECTIVE: Studies investigating medication adherence in psychosis are limited by the need of a certain degree of medication adherence and the inclusion of mostly multiple-episode patients. By contrast, noninformed consent, epidemiological studies in first-episode psychosis (FEP) allow the assessment of an important subgroup of patients who persistently refuse antipsychotic medication and thereby never receive an adequate antipsychotic trial. The present study aims to assess the prevalence and predictors of such a "medication refusal" subgroup and its association with illness outcome. METHODS: The present file audit study assessed medication adherence in an epidemiological cohort of 605 FEP patients who were treated within the Early Psychosis Prevention and Intervention Centre for up to 18 months. Medication adherence was categorized into full adherence, nonadherence, and persistent medication refusal. Predictors were analyzed using logistic regression models. RESULTS: During the 18-month treatment period, 204 patients (33.7%) were fully adherent, 287 (47.4%) displayed at least 1 phase of nonadherence, and 114 patients (18.8%) were persistent medication refusers. Poor premorbid functioning, comorbid substance use, and poor insight predicted both medication refusal and nonadherence; a forensic history and no previous contact to psychiatric care were specifically predictive of medication refusal. With respect to illness outcome, nonadherent patients were worse off when compared with fully adherent patients, and medication refusers were even worse off compared with nonadherent patients. CONCLUSIONS: Within a nonselected epidemiological FEP cohort, almost 20% of patients are persistent medication refusers. The found predictors may help to identify the individual risk of persistent medication refusal and may enable an early (preventive) treatment adaptation.

Cognitive behavioural therapy for obesity and binge eating associated to antipsychotic drugs

Background and Aims: Overweight, obesity and binge eating disorder are commonly reported in persons with severe mental disorders. Particularly, antipsychotic drugs (AP) induce weight gain in up to half of the patients. The aim of the present study is to confirm a previous study results on a larger sample of patients, to assess the impact of the interventions on other relevant dimensions of eating and weight related cognitions as well as to assess potential clinical indicators of outcomes such as AP drug, concomitant treatment with lithium or carbamazepine, psychiatric diagnostic, binge eating and severity of cognitive distortions. Method: A controlled study (12-week CBT vs. B N E) was carried out on 99 patients treated with an AP and who have gained weight following this treatment. Binge eating symptomatology, eating and weight-related cognitions, as well as weight and body mass index were assessed before treatment, at 12 weeks and at 24 weeks. Results: The findings confirms usefulness and effectiveness of the proposed CBT program on the treatment of binge symptomatology, cognitive distortions and obesity in patients treated with AP. Reduction of binge symptoms and maladapted cognitions appeared early, whereas the effect on weight appeared later during the follow up observation. No differences on outcomes were found across pharmacotherapy characteristics, diagnostic categories, binge eating nor severity of cognitive distortions. Conclusion: The proposed CBT treatment is useful for patients suffering from weight gain associated with AP treatments indeed when a concomitant treatment with lithium or valproate was given.

Association atypique d'une démence sémantique, d'un syndrome cortico-basal et d'une tauopathie 4R = [Atypical association of semantic dementia, corticobasal syndrome and 4R tauopathy]

Enjeu et contexte de la recherche La dégénérescence lobaire fronto-temporale (DLFT) est une pathologie neurodégénérative aussi fréquente que la maladie d'Alzheimer parmi les adultes de moins de 65 ans. Elle recouvre une constellation de syndromes neuropsychiatriques et moteurs dont les caractéristiques cliniques et anatomo-pathologiques se recoupent partiellement. La plupart des cas de démence sémantique ne présentent pas de troubles moteurs et révèlent à l'autopsie des lésions ubiquitine-positives. Son association à un syndrome cortico-basal et à une tauopathie 4R est donc très inhabituelle. Le cas que nous présentons est le premier à disposer d'une description clinique complète, tant sur le plan cognitif que moteur, et d'une analyse génétique et histopathologique. Résumé de l'article Il s'agit d'un homme de 57 ans, sans antécédents familiaux, présentant une démence sémantique accompagnée de symptômes inhabituels dans ce contexte, tels qu'une dysfonction exécutive et en mémoire épisodique, une désorientation spatiale et une dyscalculie. Le déclin physique et cognitif fut rapidement progressif. Une année et demie plus tard, il développait en effet des symptômes moteurs compatibles initialement avec un syndrome de Richardson, puis avec un syndrome cortico-basal. Son décès survint à l'âge de 60 ans des suites d'une pneumonie sur broncho-aspiration. L'autopsie cérébrale mit en évidence une perte neuronale et de nombreuses lésions tau-4R-positives dans les lobes frontaux, pariétaux et temporaux, les ganglions de la base et le tronc cérébral. Aucune mutation pathologique n'a été décelée dans le gène MAPT (microtubule-associated protein tau). L'ensemble de ces éléments sont discutés dans le cadre des connaissances actuelles sur la DLFT. Conclusions et perspectives Ce cas illustre le recoupement important des différents syndromes de la DLFT, parfois appelée le « complexe de Pick ». De plus, la démence sémantique pourrait s'avérer cliniquement moins homogène que prévu. Les définitions actuelles de la démence sémantique omettent la description des symptômes cognitifs extra-sémantiques malgré l'accumulation de preuves de leur existence. La faible prévalence de la démence sémantique, ainsi que des différences dans les examens neuropsychologiques, peuvent expliquer en partie la raison de cette omission. La variabilité histopathologique de chaque phénotype de DLFT peut également induire des différences dans leur expression clinique. Dans un domaine aussi mouvant que la DLFT, la co- occurrence ou la succession de plusieurs syndromes cliniques est en outre probablement la règle plutôt que l'exception.

A new locus for congenital cataract, microcornea, microphthalmia, and atypical iris coloboma maps to chromosome 2.

OBJECTIVE: To report a novel phenotype of autosomal dominant atypical congenital cataract associated with variable expression of microcornea, microphthalmia, and iris coloboma linked to chromosome 2. Molecular analysis of this phenotype may improve our understanding of anterior segment development. DESIGN: Observational case study, genome linkage analysis, and gene mutation screening. PARTICIPANTS: Three families, 1 Egyptian and 2 Belgians, with a total of 31 affected were studied. METHODS: Twenty-one affected subjects and 9 first-degree relatives underwent complete ophthalmic examination. In the Egyptian family, exclusion of PAX6, CRYAA, and MAF genes was demonstrated by haplotype analysis using microsatellite markers on chromosomes 11, 16, and 21. Genome-wide linkage analysis was then performed using 385 microsatellite markers on this family. In the 2 Belgian families, the PAX6 gene was screened for mutations by direct sequencing of all exons. MAIN OUTCOME MEASURES: Phenotype description, genome-wide linkage of the phenotype, linkage to the PAX6, CRYAA, and MAF genes, and mutation detection in the PAX6 gene. RESULTS: Affected members of the 3 families had bilateral congenital cataracts inherited in an autosomal dominant pattern. A novel form of hexagonal nuclear cataract with cortical riders was expressed. Among affected subjects with available data, 95% had microcornea, 39% had microphthalmia, and 38% had iris coloboma. Seventy-five percent of the colobomata were atypical, showing a nasal superior location in 56%. A positive lod score of 4.86 was obtained at theta = 0 for D2S2309 on chromosome 2, a 4.9-Mb common haplotype flanked by D2S2309 and D2S2358 was obtained in the Egyptian family, and linkage to the PAX6, CRYAA, or MAF gene was excluded. In the 2 Belgian families, sequencing of the junctions and all coding exons of PAX6 did not reveal any molecular change. CONCLUSIONS: We describe a novel phenotype that includes the combination of a novel form of congenital hexagonal cataract, with variably expressed microcornea, microphthalmia, and atypical iris coloboma, not caused by PAX6 and mapping to chromosome 2.

Atypical Kawasaki disease with peripheral gangrene and myocardial infarction: therapeutic implications.

We describe a 2-month-old girl with atypical Kawasaki disease (KD) complicated by peripheral gangrene and myocardial infarction. Peripheral ischaemia leading to gangrene is a rare but serious complication of KD in infants younger than 7 months of age. Treatment has been targeted at reducing arterial inflammation, arteriospasm and thrombosis. We report the first patient with incomplete KD and peripheral ischaemia in whom therapy with prostaglandin E1 (PGE1) as vasodilating and antithrombotic agent appeared successful, restoring hand and foot perfusion without significant long-term sequelae. However, PGE1 could have supported development of myocardial infarction by shunting blood away from ischaemic areas distal to a giant coronary artery aneurysm with beginning thrombosis. CONCLUSION. Atypical KD with peripheral gangrene appears to react favourably to treatment with PGE1, but needs careful monitoring to detect early signs of cardiac ischaemia.

Cognitive behavioural therapy for weight gain associated with antipsychotic drugs

BACKGROUND: Overweight and obesity are common concerns in individuals with severe mental disorders. In particular, antipsychotic drugs (AP) frequently induce weight gain. This phenomenon lacks current management and no previous controlled studies seem to use cognitive therapy to modify eating and weight-related cognitions. Moreover, none of these studies considered binge eating or eating and weight-related cognitions as possible outcomes. AIM: The main aim of this study is to assess the effectivity of cognitive and behavioural treatment (CBT) on eating and weight-related cognitions, binge eating symptomatology and weight loss in patients who reported weight gain during AP treatment. METHOD: A randomized controlled study (12-week CBT vs. Brief Nutritional Education) was carried out on 61 patients treated with an antipsychotic drug who reported weight gain following treatment. Binge eating symptomatology, eating and weight-related cognitions, as well as weight and body mass index were assessed before treatment, at 12 weeks and at 24 weeks. RESULTS: The CBT group showed some improvement with respect to binge eating symptomatology and weight-related cognitions, whereas the control group did not. Weight loss occurred more progressively and was greater in the CBT group at 24 weeks. CONCLUSION: The proposed CBT treatment is particularly interesting for patients suffering from weight gain associated with antipsychotic treatment
