Musculoskeletal Pain in Melancholic and Atypical Depression
2016
Objective. Pain and depressive disorders often present together, but little is known about the prevalence of pain in depression subgroups. The objective of this study was to examine the possible differences in the prevalence of musculoskeletal pain between participants in melancholic and atypical depression subgroups. Design. Cross-sectional study. Setting. Depression nurse case managers where depression patients receive treatment in primary health care. Subjects. Participants included 413 depression patients and 401 controls. Methods. Depressive symptoms were determined with the Beck Depression Inventory (BDI-21), and diagnosis of depression was confirmed with the Mini-International Neurop…
CD99 Immunoreactivity in Atypical Fibroxanthoma
2002
Atypical fibroxanthoma (AFX), a pleomorphic superficial cutaneous tumor of low-grade malignancy, shares many morphologic features with malignant melanoma (MM) and squamous cell carcinoma (SCC). Absence of S-100, keratin, and desmin immunoreactivity is the clue for this diagnosis. In a search for positive markers, we tested 26 cases of AFX with 2 antibodies: O13 (CD99) and protein gene product 9.5 (PGP9.5). We also included 10 cases of poorly differentiated SCC and 10 cases of MM in the study. In AFX, CD99 immunoreactivity was present in 19 cases (73%), whereas focal PGP9.5 immunoreactivity was found in only 9 cases (35%). None of the SCC cases showed CD99 immunostaining. No CD99 immunoreact…
Soft tissue recurrent ameloblastomas also show some malignant features: a clinicopathological study of a 15-year database
2015
Background To investigate the clinicopathological features of six cases of soft tissue recurrent ameloblastoma and explore the role of increased aggressive biological behavior in the recurrences and treatment of this type of ameloblastomas. Material and Methods In this study, we retrospectively reviewed recurrent ameloblastomas during a 15-year period; six cases were diagnosed as soft tissue recurrent ameloblastoma. The clinical, radiographic, cytological and immunohistochemical records of these six cases were investigated and analyzed. Results All the six soft tissue recurrent ameloblastomas occurred after radical bone resection, and were located in the adjacent soft tissues around the ost…
AML transformation in 56 patients with Ph- MPD in two well defined populations.
2009
The Philadelphia chromosome-negative (Ph-) chronic myeloproliferative disorders (MPD) have an inherent tendency for transformation into acute myelogenous leukaemia (AML). The long-term rate of leukaemic transformation in unselected MPD patients was studied in well-defined MPD populations in Gothenburg, Sweden and the Cote d'Or area, Burgundy, France, respectively. Over a median observation time of 15 yr, 56 subjects (7%) out of a total of 795 patients with Ph- MPD transformed to AML. The yearly incidence of AML transformation was 0.38% in polycythaemia vera (PV), 0.37% in essential thrombocythaemia (ET) and 1.09% in idiopathic myelofibrosis (IMF). The incidence of AML development was signif…
Oxidative stress and antioxidant response in fibroblasts from Werner and Atypical Werner Syndromes
2014
Werner Syndrome (WS, ICD-10 E34.8, ORPHA902) and Atypical Werner Syndrome (AWS, ICD-10 E34.8, ORPHA79474) are very rare inherited syndromes characterized by premature aging. While approximately 90% of WS individuals have any of a range of mutations in theWRN gene, there exists a clinical subgroup in which the mutation occurs in the LMNA/C gene in heterozygosity. Although both syndromes exhibit an age-related pleiotropic phenotype, AWS manifests the onset of the disease during childhood, while major symptoms in WS appear between the ages of 20 and 30. To study the molecular mechanisms of progeroid diseases provides a useful insight into the normal aging process. Main changes found were the d…
Seroquel (ICI 204 636), a putative "atypical" antipsychotic, in schizophrenia with positive symptomatology: results of an open clinical trial and cha…
1995
Preclinical data indicated that seroquel (ICI 204 636), a dibenzothiazepine with 5-HT2 and D2-like receptor antagonistic properties, might be an effective antipsychotic agent, causing fewer extrapyramidal side effects than typical neuroleptics. In the present study, 12 patients suffering from schizophrenia or schizophreniform disorder with predominantly positive symptomatology were treated in an open clinical trial for 4 weeks with seroquel at a maximum dosage of 750 mg/day. The drug was generally well tolerated, and virtually no adverse extrapyramidal side effects such as acute dystonia, parkinsonism or akathisia were observed. Total scores for BPRS (item score 0–6; baseline: 42.0±2.3; mea…
Time Course of 5-HT2A Receptor Occupancy in the Human Brain after a Single Oral Dose of the Putative Antipsychotic Drug MDL 100,907 Measured by Posit…
1997
MDL 100,907 is a potent and selective antagonist of 5-HT2A serotonin receptors. Animals studies suggest that MDL 100,907 may behave as an atypical antipsychotic drug. Positron emission tomograph (PET) using [11C]NMSP as the radiotracer was used to define the time course of 5-HT2 receptor occupancy in the human frontal cerebral cortex after a single oral dose of MDL 100,907 (10 or 20 mg) in nine healthy subjects. After the baseline scan each subject was studied three times post dosing at various time points. 5-HT2 occupancies were in the range of 70 and 90% after each dose. While the occupancy remains in this range over 24 hours after 20 mg MDL 100,907, it decreases by about 20% at 24 hours …
Dose-Related Effects of Amisulpride on Five Dimensions of Psychopathology in Patients With Acute Exacerbation of Schizophrenia
2002
The present analysis investigated symptom-specific dose-response relationships of the atypical antipsychotic amisulpride (AMI) in schizophrenic patients. The effects of different AMI doses on five different symptom dimensions of the Brief Psychiatric Rating Scale (BPRS) were analyzed. Results on global efficacy and safety parameters have been previously published. Four AMI doses (100 mg/day [AMI100], 400 mg/day [AMI400], 800 mg/day [AMI800], 1200 mg/day) were compared with 16 mg haloperidol (HAL16) in a multicenter, double-blind, randomized, parallel-group, 4-week trial. A total of 319 patients with acute exacerbation of schizophrenia (DSM-III-R) were included. AMI100 was compared with the …
Clinical Predictors of Response to Magnetic Seizure Therapy in Depression
2019
Objectives Magnetic seizure therapy (MST) is a novel convulsive brain stimulation method in clinical testing, which is used as an alternative for electroconvulsive therapy in patients with treatment-resistant depression (TRD). Preliminary studies have suggested that MST leads to fewer cognitive adverse effects than electroconvulsive therapy but has similar efficacy. However, the clinical predictors of response to MST have not been evaluated yet. This study aimed to investigate whether these predictors can be identified in patients with TRD. Methods Thirty-eight patients with TRD were included. As clinical predictors for treatment response, we used the diagnosis, sex, age, family history, an…
The switch from conventional to atypical antipsychotic treatment should not be based exclusively on the presence of cognitive deficits. A pilot study…
2010
Abstract Background Atypical antipsychotics provide better control of the negative and affective symptoms of schizophrenia when compared with conventional neuroleptics; nevertheless, their heightened ability to improve cognitive dysfunction remains a matter of debate. This study aimed to examine the changes in cognition associated with long-term antipsychotic treatment and to evaluate the effect of the type of antipsychotic (conventional versus novel antipsychotic drugs) on cognitive performance over time. Methods In this naturalistic study, we used a comprehensive neuropsychological battery of tests to assess a sample of schizophrenia patients taking either conventional (n = 13) or novel a…
