Poorer Outcome (poorer + outcome)
Selected AbstractsRetransplantation for recurrent hepatitis C: Positive aspectsLIVER TRANSPLANTATION, Issue 11 2003Timothy M. McCashland Key points 1. The prevalence of retransplantation for hepatitis C (HCV) patients is stable (around 40%). 2. Survival models to predict outcome of retransplantation do not show that HCV is an independent variable with poor outcomes. 3. Using Model for End-Stage Liver Disease (MELD) scores from the United Network for Organ Sharing (UNOS) database from 1996-2002, retransplantation for HCV had similar outcomes to other causes of retransplantation. 4. Poorer outcomes were noted for retransplantation with MELD scores greater than 25. 5. Minimal survival thresholds need to be developed for retransplantation for all causes of retransplantation. [source] Reducing the duration of untreated first-episode psychosis , effects on baseline social functioning and quality of lifeACTA PSYCHIATRICA SCANDINAVICA, Issue 6 2005I. Melle Objective:, Long duration of untreated psychosis (DUP) is associated with poorer outcome. The TIPS study demonstrated that DUP can be reduced through early detection (ED). As quality of life (QoL) is associated with DUP it is expected that reduction of DUP leads to better QoL. Method:, Consecutive first-episode patients with a DSM-IV diagnosis of non-organic, non-affective psychosis were included, 281 patients gave informed consent and 263 completed a full evaluation of QoL. Results:, There were no differences in subjective QoL between ED and No-ED groups attributable to reduction in DUP. There were significant bivariate differences in frequency of family and social contacts in favor of the ED group, but multivariate analyses indicated that these differences were based on differences in sample characteristics. Conclusion:, Deterioration in QoL may precede overt symptom formation. Focus on functional loss in ED educational campaigns may identify risk subjects earlier in the course of the disorder. [source] Emergency management of the morbidly obeseEMERGENCY MEDICINE AUSTRALASIA, Issue 4 2004Peter Grant Abstract Objectives: To identify the difficulties encountered with the emergency management of morbidly obese patients and formulate recommendations to streamline care. Methods: An English language literature search was undertaken using Medline (1966,2003) with key words ,morbid obesity',anaesthesia',imaging',obesity',emergency',transportation',retrieval',critical illness' and ,monitoring'. Potential articles were selected for content applicable to emergency medicine based on title and abstract and reviewed in detail. Reference lists were manually searched for further relevant articles. In view of the very limited systematic study in this area, all information deemed by the authors' to be of assistance to the emergency physician was included regardless of evidence level. Additional information was sought from standard critical care textbooks and their bibliographies and through personal communication with local ambulance and retrieval services. The authors' unpublished personal experience in providing emergency care to the morbidly obese was included for aspects of management not documented in medical literature. Results: Obesity levels and associated health problems are rapidly rising in Australia. Few studies were identified dealing with critical illness in the morbidly obese and none specifically addressing ED management. Problems identified included size related logistical issues, and limitations of physical assessment, monitoring and routine investigations. Invasive procedures, intubation and ventilation can be particularly problematic, and modified techniques may be required. Limited data indicates a poorer outcome from critical illness most marked in the case of blunt traumatic injury. Conclusion: Very obese patients present a variety of logistical and medical challenges for EDs. A series of recommendations are made based on available data. Further studies in this area would be desirable to more specifically address ED issues. [source] Successful treatment with a nicotine lozenge of smokers with prior failure in pharmacological therapyADDICTION, Issue 1 2004Saul Shiffman ABSTRACT Aims To assess the influence of unsuccessful past quit attempts using pharmacological treatment on smoking cessation when using a new nicotine lozenge. Design A double-blind, randomized, placebo-controlled trial. Setting Fifteen sites in the United Kingdom and the United States. Participants A total of 1818 smokers seeking smoking cessation treatment; 1145 had had previous pharmacological treatment with nicotine polacrilex lozenge. Intervention Lozenge, 2 mg or 4 mg (or matched placebo); a higher dose was assigned to smokers who smoked their first cigarette of the day within 30 minutes, a sign of dependence. Smokers received minimal instruction and counseling. Measurement Outcome was 28-day, CO-verified continuous abstinence at 6 weeks. Past use of medications was ascertained by self-report. Findings Lozenge was efficacious among smokers with prior pharmacotherapy as well as among those without such history. The effect of lozenge (versus placebo) was significantly greater among those with previous treatment experience, because previous treatment was associated with significantly poorer outcome on placebo, and active lozenge treatment corrected this imbalance. Lozenge efficacy was similar whether smokers had previously tried patch or acute forms of nicotine replacement therapy (gum, inhaler and spray), and also similar for past use of Zyban (bupriopion). Conclusions Smokers with a history of past failure of pharmacological treatment have lower success rates without pharmacological treatment, but equally good outcomes with active lozenge treatment. Smokers who previously tried pharmacological treatments but resumed smoking should be encouraged to try quitting again with the new nicotine lozenge. [source] Eating disturbance and severe personality disorder: outcome of specialist treatment for severe personality disorderEUROPEAN EATING DISORDERS REVIEW, Issue 2 2006Fiona Warren Abstract Objective To assess the outcome for patients receiving specialist democratic therapeutic community treatment for personality disorder (PD) when they also have eating disturbance. Method Prospective, naturalistic study. Personality psychopathology and disturbed eating attitudes of 135 male and female referrals to tertiary treatment for PD were assessed at referral. Seventy-five referrals were admitted for treatment and 60 were not. Participants were reassessed at 1-year follow-up. Results There was a significant effect of treatment on dieting but not other aspects of eating disturbance. However, patients with eating disturbance were not more likely than those without to terminate treatment early or to have poorer outcome in terms of their personality pathology. Severity of baseline personality pathology did not predict treatment response. Conclusion Clients with comorbidity should be considered for treatment of the personality disorder prior to treatment for the eating disorder.

Hendricks Background:, Dysautonomia after traumatic brain injury (TBI) is characterized by episodes of increased heart rate, respiratory rate, temperature, blood pressure, muscle tone, decorticate or decerebrate posturing, and profuse sweating. This study addresses the incidence of dysautonomia after severe TBI, the clinical variables that are associated with dysautonomia, and the functional outcome of patients with dysautonomia. Methods:, A historic cohort study in patients with severe TBI [Glasgow Coma Scale (GCS) , 8 on admission]. Results:, Seventy-six of 119 patients survived and were eligible for follow-up. The incidence of dysautonomia was 11.8%. Episodes of dysautonomia were prevalent during a mean period of 20.1 days (range 3,68) and were often initiated by discomfort. Patients with dysautonomia showed significant longer periods of coma (24.78 vs. 7.99 days) and mechanical ventilation (22.67 vs. 7.21 days). Dysautonomia was associated with diffuse axonal injury (DAI) [relative risk (RR) 20.83, CI 4.92,83.33] and the development of spasticity (RR 16.94, CI 3.96,71.42). Patients with dysautonomia experienced more secondary complications. They tended to have poorer outcome. Conclusions:, Dysautonomia occurs in approximately 10% of patients surviving severe TBI and is associated with DAI and the development of spasticity at follow-up. The initiation of dysautonomia by discomfort supports the Excitatory: Inhibitory Ratio model as pathophysiological mechanism. [source] Social deprivation and the outcomes of crisis resolution and home treatment for people with mental health problems: a historical cohort studyHEALTH & SOCIAL CARE IN THE COMMUNITY, Issue 5 2010Richard Kingsford BA (Hons) MA DipSW MSc Abstract The development of crisis resolution and home treatment (CRHT) teams has been central to the UK Government's objective of reducing reliance on hospital-based care and is supported by a growing body of evidence. However, there has been no research specifically exploring the relationship between social deprivation and CRHT teams, in spite of evidence of an association between social deprivation and increased pressure on inpatient services. This article reports a study which tested the hypothesis that social deprivation is associated with the outcome of CRHT interventions. Using a historical cohort study design, we examined a total of 260 accepted referrals to a CRHT. Social deprivation was measured by the Index of Multiple Deprivation (Office of the Deputy Prime Minister 2004) as a predictor of CRHT interventions outcomes. CRHT outcomes were dichotomised into successful and unsuccessful and were defined with reference to the CRHT operational policy. Univariate analysis found that people who lived in more socially deprived areas had a poorer outcome, as did older people and those referred from the enhanced community mental health team (CMHT). Logistic regression analysis found that age and referral source were independently associated with outcome. Analysis of the demographic data also suggested a non-significant trend towards men having less successful outcomes. Further analysis exploring the characteristics of the different referral sources to the CRHT found that those referred from the enhanced CMHT were significantly more likely to be from the most deprived area. This suggested a relationship between an enhanced level of mental health need, social deprivation and poor outcome of CRHT intervention. [source] Comorbidity and mixed anxiety-depressive disorder: clinical curiosity or pathophysiological need?HUMAN PSYCHOPHARMACOLOGY: CLINICAL AND EXPERIMENTAL, Issue S1 2001Hans-Ulrich Wittchen Abstract The paper reviews available epidemiological evidence for the existence of and the implications of comorbidity of anxiety and depressive disorders and mixed anxiety,depressive (MAD) disorders. Using epidemiolological evidence of prevalence and incidence and data relating to time-course of illness, risk factor and outcome, it is concluded: (1) that anxiety,depression comorbidity is quite frequent in epidemiological and clinical settings throughout the world; (2) this comorbidity is diagnosis-specific and is associated with increased vulnerabilities and risks as well as poorer outcome and marked disabilities; and (3) no such evidence was found for MAD disorders. Contrary to what was predicted, the prevalence of MAD disorders was quite low even when using the more recent criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition. (4) Furthermore, there was quite a heterogeneous pattern in terms of risk, severity and outcome making it questionable whether this disorder, as currently defined, is a clinical entity. These findings are discussed in terms of two perspectives, the ,lumpers' with their dimensional view and the ,splitters' with their categorical view. It is concluded that although comorbidity of threshold anxiety and depressive disorders seems to be an important phenomenon, no such evidence is provided for MAD disorders.

[source] EGFR and KRAS status of primary sarcomatoid carcinomas of the lung: Implications for anti-EGFR treatment of a rare lung malignancyINTERNATIONAL JOURNAL OF CANCER, Issue 10 2009Antoine Italiano Abstract Sarcomatoid carcinomas (SC) of the lung are uncommon malignant tumors composed of carcinomatous and sarcomatous cell components and characterized by a more aggressive outcome than other histological subtypes of nonsmall cell lung cancer (NSCLC). Although epidermal growth factor receptor (EGFR)-targeted therapies have emerged as a promising therapeutic approach in patients with advanced typical NSCLC such as adenocarcinoma, the potential clinical activity of these drugs in lung SC is still unknown. To investigate this point, we have analyzed the status of 4 EGFR pathways biomarkers in a series of lung SC. EGFR protein expression, EGFR gene copy number, EGFR mutational status and KRAS mutational status were assessed in a series of 22 consecutive cases of primary lung SC. EGFR protein overexpression was observed in all the cases. High level of polysomy (,4 copies of the gene in >40% of cells) was detected in 5 cases (23%). No EGFR mutation was detected. KRAS mutations were found in 8 patients (38%; Gly12Cys in 6 cases and Gly12Val in 2 cases). The consistent EGFR protein overexpression and the high rate of KRAS mutation may contribute to the poorer outcome of lung SC in comparison with typical NSCLC. The rare incidence of increased EGFR gene copy number, the lack of EGFR mutation and the high rate of KRAS mutation observed in our series also suggest that most patients with lung SC are not likely to benefit from anti-EGFR therapies. © 2009 UICC [source] Girls with anorexia nervosa as young adults: Personality, self-esteem, and life satisfactionINTERNATIONAL JOURNAL OF EATING DISORDERS, Issue 4 2006Inger Halvorsen MD Abstract Objective: The current study evaluated personality, self-esteem, and life satisfaction in former patients with different outcomes of childhood and adolescent-onset anorexia nervosa (AN). Methods: Forty-four female patients with AN were assessed 8.5 ± SD 3.4 years after treatment start with a clinical interview and questionnaires including the Temperament and Character Inventory (TCI) and the Rosenberg Self-Esteem Scale. Self-esteem and general life satisfaction in former patients were compared with women in a large population study. Results: Former AN patients with no eating disorder and normal eating attitudes at follow-up (n = 21 [48%]) had similar TCI profiles and self-esteem as samples from normal populations, whereas participants with poorer outcome had significantly lower TCI Self Directedness, self-esteem, and life satisfaction scores. Life satisfaction was reduced in all outcome groups and was strongly associated with self-esteem. Conclusion: Personality, self-esteem, and life satisfaction varied significantly between outcome groups. The results indicate that young patients with AN with a good outcome may have normal personality and self-esteem features in young adulthood. © 2006 by Wiley Periodicals, Inc., Int J Eat Disord, 2006 [source] Association of circulating tumor cells with tumor-related methylated DNA in patients with hormone-refractory prostate cancerINTERNATIONAL JOURNAL OF UROLOGY, Issue 5 2010Takatsugu Okegawa Objectives: To assess whether circulating tumor cells with tumor-related methylated DNA can be used to predict survival in patients with hormone-refractory prostate cancer. Methods: Blood samples from 76 patients with hormone-refractory prostate cancer were analyzed. Circulating tumor cells were enumerated with the CellSearch System in whole blood. This system was developed using an epithelial cell adhesion molecule antibody-based immunomagnetic capture and automated staining methodology. Hypermethylation at adenomatosis polyposis coli, glutathione-S-transferase-,, prostaglandin-endoperoxide synthase 2, multidrug resistance 1 and Ras association domain family 1 isoform A was analyzed using a sensitive SYBR green methylation-specific polymerase chain reaction. Patient charts were retrospectively examined. Results: Median overall survival time was 19.3 months (range 11,48). Of the 76 patients, 47 (62%) had five or more circulating tumor cells, with a median overall survival of 12.0 months compared with 26.0 months for patients with fewer than five circulating tumor cells (P < 0.001). Circulating tumor cells were detected in 36 of 39 (92%) patients with tumor-related methylated DNA but only 11 of 37 (30%) patients without methylated DNA (P < 0.001). Thirty-nine (51%) patients had one or more methylated marker. Their median overall survival time was 12.0 months compared with 48.0 months or more for patients without methylated DNA (P < 0.001). Prostate-specific antigen-doubling time, circulating tumor cells and methylated DNA were independent predictors of overall survival time. Conclusions: Hormone refractory prostate cancer patients with circulating tumor cells and/or tumor-related methylated DNA show a significantly poorer outcome than those without these blood markers. [source] Critical role of ribavirin for the achievement of early virological response to HCV therapy in HCV/HIV-coinfected patientsJOURNAL OF VIRAL HEPATITIS, Issue 6 2007B. Ramos Summary., The response to hepatitis C virus (HCV) therapy seems to be lower in HCV/HIV-coinfected patients than in HCV-monoinfected individuals. Given that most pivotal trials conducted in coinfected patients have used the combination of pegylated interferon (pegIFN) along with fixed low doses (800 mg/day) of ribavirin (RBV), it is unclear whether HIV itself and/or suboptimal RBV exposure could explain this poorer outcome. Two well-defined end points of early virological response were evaluated in Peginterferon Ribavirina España Coinfección (PRESCO), a multicentre trial in which the combination of pegIFN plus RBV (1000 mg if body weight <75 kg and 1200 mg if >75 kg) was prescribed to coinfected patients. For comparisons, we used unpublished data from early kinetics in two other large trials, one performed in HIV-negative patients [Pegasys International Study Group (PISG)] in which RBV 1000,1200 mg/day was used and another [AIDS Pegasys Ribavirin Coinfection Trial (APRICOT)] in which HIV-positive patients received fixed low RBV doses (800 mg/day). A total of 348 HCV/HIV-coinfected patients from the PRESCO trial were analysed as well as all patients treated with pegIFN plus RBV, who completed 12 weeks of therapy in the comparative studies (435 in PISG and 268 in APRICOT). Negative serum HCV-RNA at week 4 (which has the highest positive predictive value of sustained virological response, SVR) was attained in 33.3%, 31.2% and 13% of treated patients with HCV genotype 1, respectively, in PRESCO, PISG and APRICOT. For HCV genotypes 2/3, responses were 83.7%, 84.2% and 37%, respectively. A decline lower than 2 log10 at week 12 (which has the highest negative predictive value of SVR) was seen in 25.5%, 19.5% and 37% of HCV genotype-1-infected patients, and in 2.1%, 2.9% and 12% of genotypes-2/3-infected patients, respectively. Prescription of high RBV doses enhances the early virological response to HCV therapy in HCV/HIV-coinfected patients, with results approaching those seen in HCV-monoinfected patients. [source] Patients' conceptions of the cause of their rheumatoid arthritis: A qualitative studyMUSCULOSKELETAL CARE, Issue 4 2009MScN, Ulrika Bergsten RN Abstract Background:,Patients' perspective of the causes and consequences of rheumatoid arthritis (RA) can conflict with that of healthcare professionals and lead to misunderstanding, difficulties in management and a poorer outcome. Objectives:,The aim of this study was to describe the variation in how patients' conceive the cause of their RA. Methods:,An open written question from the Epidemiological Investigation of Rheumatoid Arthritis (EIRA) study, aimed at patients recently diagnosed with RA, was answered by 38 strategically selected patients during 2003 and analysed using the phenomenographic approach. Results:,Two descriptive categories and six concepts emerged: the category ,consequences beyond personal control' comprised not having a clue, being exposed to climatic change, being genetically exposed and unexpected effects of events; the category ,overloaded circumstances' involved work and family-related strain. Consequences beyond personal control implied that the patients could not prevent the disease and expressed their lack of understanding as to why they contracted it. Overloaded circumstances were described as strained situations that were both work and family related and could be influenced by the patient. Conclusions:,The patient's perspective of the cause of their RA includes aspects that complement the current pathogenetic models and should therefore be considered in the management of the disease. When dealing with rheumatic diseases, it is necessary to be aware of the patient's perspectives in order to new management strategies. In addition to epidemiological studies, further studies of patients' own experience are needed in order to achieve a more tailored care model. Copyright © 2009 John Wiley & Sons, Ltd [source] Pretreatment Psychosocial Variables as Predictors of Outcomes Following Lumbar Surgery and Spinal Cord Stimulation: A Systematic Review and Literature SynthesisPAIN MEDICINE, Issue 4 2009James Celestin MD ABSTRACT Background., In the multimodal treatment approach to chronic back pain, interventional back procedures are often reserved for those who do not improve after more conservative management. Psychological screening prior to lumbar surgery or spinal cord stimulation (SCS) has been widely recommended to help identify suitable candidates and to predict possible complications or poor outcome from treatment. However, it remains unclear which, if any, variables are most predictive of pain-related treatment outcomes. Objective., The intent of this article is to perform a systematic review to examine the relationship between presurgical predictor variables and treatment outcomes, to review the existing evidence for the benefit of psychological screening prior to lumbar surgery or SCS, and to make treatment recommendations for the use of psychological screening. Results., Out of 753 study titles, 25 studies were identified, of which none were randomized controlled trials and only four SCS studies met inclusion criteria. The methodological quality of the studies varied and some important shortcomings were identified. A positive relationship was found between one or more psychological factors and poor treatment outcome in 92.0% of the studies reviewed. In particular, presurgical somatization, depression, anxiety, and poor coping were most useful in helping to predict poor response (i.e., less treatment-related benefit) to lumbar surgery and SCS. Older age and longer pain duration were also predictive of poorer outcome in some studies, while pretreatment physical findings, activity interference, and presurgical pain intensity were minimally predictive. Conclusions., At present, while there is insufficient empirical evidence that psychological screening before surgery or device implantation helps to improve treatment outcomes, the current literature suggests that psychological factors such as somatization, depression, anxiety, and poor coping, are important predictors of poor outcome. More research is needed to show if early identification and treatment of these factors through psychological screening will enhance treatment outcome. [source] Alterations of DNA methylation and clinicopathological diversity of human cancersPATHOLOGY INTERNATIONAL, Issue 9 2008Yae Kanai Alterations of DNA methylation can account for the histological heterogeneity, reflected in the stepwise progression and complex biological characteristics of human cancers, that genetic alterations alone cannot explain. Analysis of DNA methylation status in tissue samples can be an aid to understanding the molecular mechanisms of multistage carcinogenesis. Human cancer cells show a drastic change in DNA methylation status, that is, overall DNA hypomethylation and regional DNA hypermethylation, which results in chromosomal instability and silencing of tumor-suppressor genes. Overexpression of DNA methyltransferase (DNMT) 1 is not a secondary result of increased cell proliferative activity but may underline the CpG island methylator phenotype of cancers. Splicing alteration of DNMT3B may result in chromosomal instability through DNA hypomethylation of pericentromeric satellite regions. Alterations of DNA methylation are observed even in the precancerous stage frequently associated with chronic inflammation and/or persistent viral infection or with cigarette smoking. Precancerous conditions showing alterations of DNA methylation may generate more malignant cancers. Aberrant DNA methylation is significantly associated with aggressiveness of cancers and poorer outcome of cancer patients. Genome-wide analysis of DNA methylation status based on array-based technology may identify DNA methylation profiles that can be used as appropriate indicators for carcinogenetic risk estimation and prognostication. [source] Outcome of 122 pregnancies in essential thrombocythemia patients: A report from the Italian registryAMERICAN JOURNAL OF HEMATOLOGY, Issue 10 2009Lorella Melillo Pregnancy is a high-risk event in women with essential thrombocythemia (ET). This observational study evaluated pregnancy outcome in ET patients focusing on the potential impact of aspirin (ASA) or interferon alpha (IFN) treatment during pregnancy. We retrospectively analyzed 122 pregnancies in 92 women consecutively observed in the last 10 years in 17 centers of the Italian thrombocythemia registry (RIT). The live birth rate was 75.4% (92/122 pregnancies). The risk of spontaneous abortion was 2.5-fold higher than in the control population (P < 0.01). ASA did not affect the live birth rate (71/93, 76.3% vs. 21/29, 72.4%, P = 0.67). However, IFN treatment during pregnancy was associated with a better outcome than was management without IFN (live births 19/20, 95% vs. 73/102, 71.6%, P = 0.025), and this finding was supported by multivariate analysis (OR: 0.10; 95% CI: 0.013,0.846, P = 0.034). The JAK2 V617F mutation was associated with a poorer outcome (fetal losses JAK2 V617F positive 9/25, 36% vs. wild type 2/24, 8.3%, P = 0.037), and this association was still significant after multivariate analysis (OR: 6.19; 95% CI: 1.17,32.61; P = 0.038). No outcome concordance between first and second pregnancies was found (P = 0.30). Maternal complications occurred in 8% of cases. In this retrospective study, in consecutively observed pregnant ET patients, IFN treatment was associated with a higher live birth rate, while ASA treatment was not. In addition, the JAK2 V617F mutation was confirmed to be an adverse prognostic factor. Am. J. Hematol. 2009. © 2009 Wiley-Liss, Inc. [source] Sex Differences in Outcomes of Sinus Surgery,THE LARYNGOSCOPE, Issue 7 2006Sabrina Mendolia-Loffredo MS Abstract Purpose: Sex has been demonstrated to affect outcome in many diseases. Our current aim is to investigate the relationship between sex and outcomes of endoscopic sinus surgery (ESS) in patients with chronic rhinosinusitis (CRS). Methods: Forty-four males and 73 females undergoing ESS for CRS with a mean follow-up of 1.4 years were evaluated prospectively. Computed tomography (CT), endoscopy, and quality of life (QOL) assessment was performed. Univariate analyses were performed to evaluate whether sex was predictive of outcome. Multiple logistic regression analysis was performed to evaluate sex association with patient factors predictive of outcome. Results: Although no sex differences in CT and endoscopy were observed (CT, P = .107 and endoscopy, P > .1), females consistently scored worse than males on disease-specific QOL pre- and postoperatively. Importantly, there was no effect of sex on improvement/change scores for the QOL instruments. Predictive Models and Multiple Logistic Regression Analysis: Sex was not found to be predictive of QOL or endoscopic outcome. Female sex was, however, associated with acetylsalicylic acid (ASA) intolerance and depression, both factors that have been associated with poorer outcome. Conclusion: Despite similarities in objective disease measures, females report significantly worse QOL scores pre- and postoperatively. Postoperative improvement did not differ by sex, nor was sex predictive of postoperative outcome. Sex differences in QOL reflect sex differences in ASA intolerance and depression, both more prevalent in females. [source] Conjunctival Melanoma: The Role of Conservative Surgery and Radiotherapy in Regional Metastatic DiseaseTHE LARYNGOSCOPE, Issue 5 2005Taran Tatla MRCS Abstract Objective: To evaluate prognostic factors and determine the role of conservative surgery and radiotherapy in managing metastatic conjunctival malignant melanoma (MM) involving preauricular/submandibular lymph nodes. Method: A retrospective analysis (1990,2003) of clinical and histopathologic data from 12 patients presenting with regional metastases after failed local treatment for conjunctival MM. Patients received a common, multispecialty, conservative management approach: wide local excision, topical cryotherapy or radiotherapy to conjunctival MM (orbital exenteration for more advanced local disease), lumpectomy, and adjuvant "ring" radiotherapy of regional metastases, with chemotherapy for distant metastases. Results: Median age at primary diagnosis was 51 (range 28,86) years with equal sex predilection. Six of the 12 patients had primary tumors of the bulbar conjunctiva; the remainder arose in the palpebral conjunctiva, the caruncle, or the fornix. Of 11 originating in primary acquired melanosis (PAM), 2 were amelanotic. Epithelioid tumor cells were noted histologically in seven of eight specimens in which cell type could be determined. Eight tumors metastasised to preauricular nodes, three to submandibular and one to both, with a median interval of 23 (range 12,108) months after primary diagnosis. After conservative surgery and "ring irradiation," 7 of 12 patients remained free of regional nodal relapse at median interval of 16 (range 3,126) months. Five patients developed regional nodal recurrence at median interval of 11 (range 6,13) months, 3 of whom were within radiotherapy portals. Eight patients developed distant metastasis at median interval of 44 (range 22,138) months. Eleven patients had tumor-related death. The mean Kaplan-Meier adjusted survival time after primary diagnosis was 76 months with death ensuing postregional metastasis within a median 18 (range 4,127) months. The sole survivor's follow-up duration was 56 months. Conclusion: Locoregional metastasis after treatment for conjunctival MM is associated with a poor prognosis. Both epithelioid tumor cells and PAM are associated with disseminating disease and poorer outcome. Literature review has failed to demonstrate advantages of mutilating radical surgery over a conservative approach in this rare disease. [source] Cyclin D1 Amplification and p16(MTS1/CDK4I) Deletion Correlate With Poor Prognosis in Head and Neck Tumors,THE LARYNGOSCOPE, Issue 3 2002Ali Namazie MD Abstract Objectives/Hypothesis Cyclin D1, a cell cycle regulator localized to chromosome 11q13, is amplified in several human tumors including head and neck squamous cell carcinoma (HNSCC). Amplification and/or overexpression of cyclin D1 have been correlated to a poor prognosis. Deletion of the p16 gene, localized to 9p21, has also been observed in a significant proportion of HNSCC. The p16 gene regulates cyclin D1-CDK4 activity and prevents retinoblastoma tumor suppressor gene phosphorylation, thereby downregulating cellular proliferation. Detection of cyclin D1 amplification and p16 deletion using a simple and sensitive method will be valuable for the development of effective treatment modalities for head and neck cancer. Study Design We have used fluorescence in situ hybridization (FISH) to study cyclin D1 amplification and p16 gene deletion in head and neck tumors. Both single- and dual-color FISH were performed. Methods Paraffin-embedded tissues from 103 patients with HNSCC were analyzed using genomic DNA probes for cyclin D1 and p16. Dual-color FISH was performed with chromosome 11 or 9 centromeric probes as a control. Twenty-eight of these samples were analyzed for p16 expression by immunohistochemistry. Results Cyclin D1 amplification was observed in 30% (31/103) of patients, and p16 deletion in 52% (54/103). Lack of p16 expression was observed in 64% (18/28) of patients. There was a good correlation between the deletion of p16 sequences and the loss of p16 expression (P = .008). Amplification of cyclin D1 had a statistically significant association with recurrence, distant metastasis, and survival at 36 months. There was a significant association between p16 deletion and the development of distant metastases. Cyclin D1 amplification and p16 deletion together correlated with recurrence, distant metastasis, and survival. Conclusions We demonstrate that FISH is a simple and sensitive method for detecting cyclin D1 amplification and p16 deletion in head and neck cancer. Our results suggest that these two genetic aberrations together portend a poorer outcome than either of the abnormalities alone in head and neck cancer. [source] Cortical folding difference between patients with early-onset and patients with intermediate-onset bipolar disorderBIPOLAR DISORDERS, Issue 4 2009Jani Penttilä Objectives:, Cerebral abnormalities have been detected in patients with bipolar disorder (BD). In comparison to BD with a later onset, early-onset BD has been found to have a poorer outcome. However, it is yet unknown whether neuroanatomical abnormalities differ between age-at-onset subgroups of the illness. We searched for cortical folding differences between early-onset (before 25 years) and intermediate-onset (between 25 and 45 years) BD patients. Methods:, Magnetic resonance images of 22 early-onset BD patients, 14 intermediate-onset BD patients, and 50 healthy participants were analyzed using a fully automated method to extract, label, and measure the sulcal area in the whole cortex. Cortical folding was assessed by computing global sulcal indices (the ratio between total sulcal area and total outer cortex area) for each hemisphere, and local sulcal indices for 12 predefined regions in both hemispheres. Results:, Intermediate-onset BD patients had a significantly reduced local sulcal index in the right dorsolateral prefrontal cortex in comparison to both early-onset BD patients and healthy subjects, and lower global sulcal indices in both hemispheres in comparison to healthy subjects (p < 0.05, Bonferroni corrected). Brain tissue volumes did not differ between groups. Conclusions:, This study provided the first evidence of a neuroanatomic difference between intermediate-onset and early-onset BD, which lends further support to the existence of different age-at-onset subgroups of BD. [source] Psychoeducation in bipolar patients with comorbid personality disordersBIPOLAR DISORDERS, Issue 4 2004Francesc Colom Background:, The co-occurrence of personality and bipolar disorders is quite common. Bipolar patients with personality disorders have been described as having poorer outcome than ,pure' bipolar patients. However, from a combined-approach point of view, a little has been done to improve the course of these patients. Psychoeducation has shown its efficacy in the prevention of relapses in the bipolar population but, to date, no data is available on its efficacy in the management of bipolar patients with personality disorders. Method:, The present study shows a subanalysis from a single-blind randomized prospective clinical trial on the efficacy of group psychoeducation in bipolar I patients. Bipolar patients fulfilling DSM-IV criteria for any personality disorder were randomized to either psychoeducational treatment or a non-structured intervention. There were 22 patients in the control group and 15 in the psychoeducation group. All patients received naturalistic pharmacological treatment as well. The follow-up phase comprised 2 years where all patients continued receiving naturalistic treatment without psychological intervention and were assessed monthly for several outcome measures. Results:, At the end of the follow-up phase (2 years), a 100% of control group patients fulfilled criteria for recurrence versus a 67% in the psychoeducation group (p < 0.005). Patients included in the psychoeducation group had a higher time-to-relapse and a significantly lower mean number of total, manic and depressive relapses. No significant differences regarding the number of patients who required hospitalization were found but the mean duration of days spent in the hospitalization room was significantly higher for the patients included in the control group. Conclusion:, Psychoeducation may be a useful intervention for bipolar patients with comorbid personality disorders. Further studies should address the efficacy of specifically tailored interventions for this common type of patients. [source] Is there a benefit to sentinel lymph node biopsy in patients with T4 melanoma?CANCER, Issue 24 2009Csaba Gajdos MD Abstract BACKGROUND: Controversy exists as to whether patients with thick (Breslow depth >4 mm), clinically lymph node-negative melanoma require sentinel lymph node (SLN) biopsy. The authors examined the impact of SLN biopsy on prognosis and outcome in this patient population. METHODS: A review of the authors' institutional review board-approved melanoma database identified 293 patients with T4 melanoma who underwent surgical excision between 1998 and 2007. Patient demographics, histologic features, and outcome were recorded and analyzed. RESULTS: Of 227 T4 patients who had an SLN biopsy, 107 (47%) were positive. The strongest predictors of a positive SLN included angiolymphatic invasion, satellitosis, or ulceration of the primary tumor. Patients with a T4 melanoma and a negative SLN had a significantly better 5-year distant disease-free survival (DDFS) (85.3% vs 47.8%; P < .0001) and overall survival (OS) (80% vs 47%; P < .0001) compared with those with metastases to the SLN. For SLN-positive patients, only angiolymphatic invasion was a significant predictor of DDFS, with a hazard ratio of 2.29 (P = .007). Ulceration was not significant when examining SLN-positive patients but the most significant factor among SLN-negative patients, with a hazard ratio of 5.78 (P = .02). Increasing Breslow thickness and mitotic rate were also significantly associated with poorer outcome. Patients without ulceration or SLN metastases had an extremely good prognosis, with a 5-year OS >90% and a 5-year DDFS of 95%. CONCLUSIONS: Clinically lymph node-negative T4 melanoma cases should be strongly considered for SLN biopsy, regardless of Breslow depth. SLN lymph node status is the most significant prognostic sign among these patients. T4 patients with a negative SLN have an excellent prognosis in the absence of ulceration and should not be considered candidates for adjuvant high-dose interferon.

[source] Long-term outcome of patients with insular carcinoma of the thyroidCANCER, Issue 10 2002The insular histotype is an independent predictor of poor prognosis Abstract BACKGROUND Insular thyroid carcinoma was described originally as a tumor with aggressive behavior. However, whether a predominant insular component is an independent factor for poor prognosis is unclear. METHODS The authors compared the clinical behavior of tumors in three groups of patients with thyroid carcinoma,13 patients with insular thyroid carcinoma, 18 patients with follicular thyroid carcinoma, and 26 patients with papillary thyroid carcinoma,who were selected based on similar tumor size and similar age. Disease free survival and disease specific deaths were assessed in the three groups with a Kaplan,Meier analysis and were compared using the log-rank test. Cox regression analysis was used to evaluate the influence of histotype and other prognostic factors on the occurrence of distant metastases and disease specific death. RESULTS Patient follow-up ranged from 5.2 months to 190.0 months. At last follow-up, only 1 of 13 patients (7.7%) with insular carcinoma, compared with 8 of 18 patients (44.4%) with follicular carcinoma and 12 of 26 patients (46.1%) with papillary carcinoma, were disease free. The disease specific death rate was 61.5% among patients in the insular carcinoma group compared with 16.7% and 15.4% among patients in the follicular carcinoma group (P = 0.006) and the papillary carcinoma group (P = 0.025), respectively. At multivariate analysis, the insular histotype was the only variable that was related independently to disease specific death (hazard ratio = 4.27; P = 0.005). Distant metastases occurred in 84.6% of patients in the insular carcinoma group compared with 50% and 19.2% of patients in the follicular carcinoma group (P = 0.039) and the papillary carcinoma group (P = 0.0003), respectively. All metastases from patients with insular carcinomas (n = 11 patients) showed radioiodine uptake, but a clinical benefit from this treatment was observed only in 1 patient. CONCLUSIONS Patients with insular thyroid carcinoma have a poorer outcome compared with patients of similar age who have differentiated types of thyroid carcinoma with tumors of a similar size. Because radioiodine rarely is effective in the treatment of patients with metastatic insular thyroid carcinoma, novel and possible multimodal therapies should be explored for the treatment of patients with these aggressive tumors.

DOI 10.1002/cncr.10947 [source] Results from the International Cataract Surgery Outcomes StudyACTA OPHTHALMOLOGICA, Issue thesis2 2007Jens Christian Norregaard MD Abstract It is widely accepted that cataract extraction with intraocular lens implantation is a highly effective and successful procedure. However, quality assessments and studies of effectiveness should still be undertaken. As with any surgical treatment modality, complications may occur, leading to suboptimal outcomes, additional health costs and deterioration in patients' functional capacity. International variation in clinical practice patterns and outcomes can serve as important pointers in the attempt to identify areas amenable to improvements in quality and cost-effectiveness. Once demonstrated, similar clinical results obtained in different health care systems can improve the level of confidence in a clinical standard against which the quality of care can be evaluated. The International Cataract Surgery Outcomes Study was established in 1992. The objective of this international comparative research project was to compare cataract management, outcomes of surgery and quality of care in four international sites. The study was conducted in the 1990s, since when many developments and refinements have emerged within cataract surgery. The actual figures reported in this thesis may no longer be of specific relevance as a decade has passed since their collection. However, the research questions and methods used in the study are still highly important and justify the publication of this report. The report deals with problems related to quality assessment, benchmarking, and the establishment and design of nationwide clinical databases , issues that are currently the focus of much attention. Moreover, the problems related to cross-national comparisons are increasingly relevant as more international databases are established. The study makes suggestions on how to report and compare objective as well as subjective criteria for surgery. The issue of how to report subjective criteria is a particular subject of current discussion. Four sites with high-quality health care systems were examined in this study: the USA, Denmark, the Province of Manitoba (Canada), and Barcelona (Spain). The design of the international research programme was based on methods developed by the US National Cataract Surgery Outcomes Study conducted by the US Cataract Patients Outcomes Research Team. The International Cataract Surgery Outcomes Study comprised three separate studies: a survey of ophthalmologists; a prospective cohort study, and a retrospective register-based cohort study. The survey study was based on data generated by a self-administered questionnaire completed by ophthalmologists in the four study areas. The questionnaire examined routine clinical practice involving patients considered for cataract surgery, and included questions on anaesthesia, monitoring and surgical techniques. The prospective cohort study was a large-scale, longitudinal observational study of patients undergoing first-eye cataract surgery in each study site. Patients were sampled consecutively from multiple clinics and followed for 4 months postoperatively. The retrospective cohort study was based on the Danish National Patient Register and claims data from the USA. This study could not be carried out in Barcelona or Manitoba as no suitable administrative databases were available. The papers based on register databases deal with retinal detachment and endophthalmitis but are not included in this thesis as the material was previously reported in my PhD thesis. The application of the studies was highly co-ordinated among the four sites and similar methods and instruments were used for data collection. The development of the data collection strategy, questionnaires, clinical data forms and data analyses were co-ordinated through weekly telephone conferences, annual in-person conferences, correspondence by mail or fax, and the exchange of sas programs and data files via the Internet. The survey study was based on responses from 1121 ophthalmologists in the four sites and results were presented in two papers. Within the previous year the participating ophthalmologists had performed a total of 212 428 cataract surgeries. With regard to preoperative ophthalmic testing, the present study reveals that refraction, fundus examination and A-scanning were performed routinely by most surgeons in all four sites. Other tests were reported to be performed routinely by some surgeons. It is unclear why any surgeon would use these other tests routinely in cataract patients with no ocular comorbidity. It appears that if this recommendation from the US Clinical Practice Guidelines Panel was broadly accepted, the use of these procedures and costs of care could be reduced, especially in Barcelona, the USA and Canada. Restricted use of medical screening tests was reported in Denmark. If this restricted screening were to be implemented in the USA, Canada and Barcelona, it would have significant resource implications. The most striking finding concerned the difference in monitoring practice between Denmark and each of the other three sites. In Denmark, monitoring equipment is seldom used and only occasionally is an anaesthesiologist present during cataract surgery. By contrast, in the other study sites, the presence of an anaesthesiologist using monitoring equipment is the norm. Adopting the Danish model in other sites would potentially yield significant cost savings. The results represent part of the background data used to inform the decision to conduct the two large-scale, multicentre Studies of Medical Testing for Cataract Surgery. The current study is an example of how surveys of clinical practice can pinpoint topics that need to be examined in randomized clinical trials. For the second study, 1422 patients were followed from prior to surgery until 4 months postoperatively. Preoperatively, a medical history was obtained and an ophthalmic examination of each patient performed. After consent had been obtained, patients were contacted for an in-depth telephone interview. The interview was repeated 4 months postoperatively. The interview included the VF-14, an index of functional impairment in patients with cataract. Perioperative data were available for 1344 patients (95%). The 4-month postoperative interview and clinical examination were completed by 1284 patients (91%). Main reasons for not re-evaluating patients were: surgery was cancelled (3%); refusal to participate (2%); lost to follow-up (1%), and death or being too sick (1%). The results have been presented in several papers, of which four are included in this thesis. One paper compared the preoperative clinical status of patients across the four sites and showed differences in both visual acuity (VA) and VF-14 measures. The VF-14 is a questionnaire scoring disability related to vision. The findings suggest that indications for surgery in comparable patients were similar in the USA and Denmark and were more liberal than in Manitoba and Barcelona. The results highlight the need to control for patient case mix when making comparisons among providers in a clinical database. This information is important when planning national databases that aim to compare quality of care. A feasible method may be to use one of the recently developed systems for case severity grading before cataract surgery. In another paper, perioperative clinical practice and rates of early complications following cataract surgery were compared across the four health care systems. Once again, the importance of controlling for case mix was demonstrated. Significant differences in clinical practice patterns were revealed, suggesting a general trend towards slower diffusion of new medical technology in Europe compared with North America. There were significant differences across sites in rates of intra- and early postoperative events. The most important differences were seen for rates of capsular rupture, hyphaema, corneal oedema and elevated pressure. Rates of these adverse events might potentially be minimized if factors responsible for the observed differences could be identified. Our results point towards the need for further research in this area. In a third paper, 4-month VA outcomes were compared across the four sites. When mean postoperative VA or crude proportions of patients with a visual outcome of <,0.67 were compared across sites, a much poorer outcome was seen in Barcelona. However, higher age, poorer general health status, lower preoperative VA and presence of ocular comorbidity were found to be significant risk factors associated with increased likelihood of poorer postoperative VA. The proportions of patients with these risk factors varied across sites. After controlling for the different distributions of these factors, no significant difference remained across the four sites regarding risk of a poor visual outcome. Once again the importance of controlling for case mix was demonstrated. In the fourth paper, we examined the postoperative VF-14 score as a measure of visual outcomes for cataract surgery in health care settings in four countries. Controlling for case mix was also necessary for this variable. After controlling for patient case mix, the odds for achieving an optimal visual function outcome were similar across the four sites. Age, gender and coexisting ocular pathology were important predictors of visual functional outcome. Despite what seemed to be an optimal surgical outcome, a third of patients still experienced visual disabilities in everyday life. A measure of the VF-14 might help to elucidate this issue, especially in any study evaluating the benefits of cataract surgery in a public health care context. [source] Congenital chylothorax: from foetal life to adolescenceACTA PAEDIATRICA, Issue 10 2010S Caserío Abstract Aim:, To analyse the main prenatal and postnatal features of congenital chylothorax (CC), and the outcome including mid-term follow-up. Methods:, We searched our databases for CC diagnosed between 1990 and 2006. Data of 29 cases were retrieved and analysed. Follow-up until 3 years of age was available for all patients. Results:, Most patients were diagnosed prenatally (94%) and most cases were complicated by foetal hydrops (66.7%). The overall survival rate at 3 years was 56%. A significantly poorer outcome was observed when foetal hydrops, preterm birth < 34 weeks, large effusions and/or early-onset pneumothorax were present. An important but not significant improvement in the survival rate was observed through the study period; while in 1990,1998, the survival rate was 41.7%, from 1999 to 2006 it was 66.7% (p = 0.19). In the mid-term follow-up, we did not observe any recurrence of CC and most infants remain asymptomatic. However, 27% of survivors were diagnosed as having asthma in early infancy. Conclusion:, CC still carries a significant risk of perinatal mortality. However, continuous advances in foetal and neonatal medicine are improving the prognosis of these patients, and nowadays most of them are likely to survive. Beyond the neonatal period, most survivors have an uneventful outcome. [source] Morbidity in children born to women infected with human immunodeficiency virus in South Africa: does mode of feeding matter?ACTA PAEDIATRICA, Issue 8 2003A Coutsoudis Aim: To examine infant morbidity risks associated with refraining from breastfeeding where it is used in an attempt to prevent mother-to-child transmission (MTCT) of human immunodeficiency virus (HIV). Methods: The population consisted of infants born to HIV-infected women in South Africa who were participating in a vitamin A intervention trial to prevent MTCT of HIV. Women chose to breastfeed or formula feed their infants according to UNAIDS guidelines. Actual feeding practices and morbidity were recorded at clinic follow-up visits at 1 wk, 6 wk, 3 mo and every 3 mo thereafter until 15 mo of age or cessation of breastfeeding. The infant's HIV status was assessed according to a predetermined algorithm. Results: HIV-infected infants who were never breastfed had a poorer outcome than those who were breastfed; 9 (60%) of those who were never breastfed had 3 or more morbidity episodes compared with 15 (32%) of breastfed children [odds ratio (OR) 4.05, 95% confidence interval (95% CI) 0.91,20.63, p = 0.05]. During the first 2 mo of life, never-breastfed infants (regardless of HIV status) were nearly twice as likely to have had an illness episode than breastfed infants (OR 1.91, 95% CI 1.17-3.13, p = 0.006). Conclusion: The significant extra morbidity experienced in the first few months by all never-breastfed infants and at all times by HIV-infected infants who are not breastfed needs to be considered in all decisions by mothers, health workers and policy makers so as not to offset any gains achieved by decreasing HIV transmission through avoiding breastfeeding. [source] Role of transarterial chemoembolization for hepatocellular carcinoma before liver transplantation with special consideration of tumor necrosisCLINICAL TRANSPLANTATION, Issue 2009André Schaudt Abstract:, Several authors suggest that local ablative therapies, specifically transarterial chemoembolization (TACE), may control tumor progression of hepatocellular carcinoma (HCC) in patients who are on the waiting list for liver transplantation (orthotopic liver transplantation, OLT). There is still no evidence if TACE followed by OLT is able to prevent recurrence of tumor, to prolong survival rate of the patients on the waiting list, or to improve the survival after OLT. We report 27 patients with HCC who underwent OLT. From these patients, 15 were pre-treated with TACE alone or in combination with percutaneous ethanol injection (PEI) or laser-induced thermo therapy (LITT). Mean time on the waiting list was 214 d for treated patients and 133 d for untreated patients. Comparing pre-operative imaging and histopathological staging post-transplant, we found 13 patients with tumor progression out of which five were treated with TACE. In two of the TACE patients a decrease of lesions could be achieved. In a single patient, there was no evidence of any residual tumor. Only one patient displayed tumor progression prior to OLT despite undergoing TACE. Comparison of outcome in patients undergoing TACE or having no TACE was not statisitically significant (p = 0.5). In addition, our analysis showed that progression either in the total study population or in the TACE group alone is associated with a significant poorer outcome concerning overall survival (p = 0.02 and p = 0.02). [source] United Network for Organ Sharing's expanded criteria donors: is stratification useful?,CLINICAL TRANSPLANTATION, Issue 3 2005Edwina S. Baskin-Bey Abstract:, The United Network for Organ Sharing (UNOS) Expanded Criteria Donor (ECD) system utilizes pre-transplant variables to identify deceased donor kidneys with an increased risk of graft loss. The aim of this study was to compare the ECD system with a quantitative approach, the deceased donor score (DDS), in predicting outcome after kidney transplantation. We retrospectively reviewed 49 111 deceased donor renal transplants from the UNOS database between 1984 and 2002. DDS: 0,39 points; ,20 points defined as marginal. Recipient outcome variables were analyzed by ANOVA or Kaplan,Meier method. There was a 90% agreement between the DDS and ECD systems as predictors of renal function and graft survival. However, DDS identified ECD, kidneys (10.7%) with a significantly poorer outcome than expected (DDS 20,29 points, n = 5,252). Stratification of ECD+ kidneys identified a group with the poorest outcome (DDS ,30 points). Predictability of early post-transplant events (i.e. need for hemodialysis, decline of serum creatinine and length of hospital stay) was also improved by DDS. DDS predicted outcome of deceased donor renal transplantation better than the ECD system. Knowledge obtained by stratification of deceased donor kidneys can allow for improved utilization of marginal kidneys which is not achieved by the UNOS ECD definition alone. [source] Surgical resection of colorectal liver metastasesCOLORECTAL DISEASE, Issue 6 2001M. A. Memon Background Liver metastases are a major cause of death in patients with colorectal carcinoma. The only curative option available at present is surgery. This review article discusses the current state of evidence for the effectiveness of liver resection for patients with liver metastases from colorectal cancer. Methods Medline, Embase, Current Contents and Science Citation Index databases were used to search English language articles published on the subject of liver resection for colorectal metastases in the last 20 years. Results Liver resection has a five year survival of 16,49% and 10 year survival of 17,33% with an operative mortality rate of 0,9%. Two factors appear to be clearly associated with poorer outcome , involved resection margins and the presence of extrahepatic disease (including hilar and coeliac axis lymph nodes) at the time of liver resection. None of the other factors related to the patients, their primary tumour or the metastases themselves have been conclusively shown to adversely effect long-term survival. Conclusions Liver resection is a feasible, safe and effective procedure which carries an acceptable morbidity and mortality and does have a major impact on the survival of these patients. The decision on resectability of colorectal metastases should be decided by the ability to leave at least 2,3 segments of liver free from metastases with uninvolved resection margins, together with the general fitness of the patient to undergo a major surgical procedure. [source] The rationale for early intervention in schizophrenia and related disordersEARLY INTERVENTION IN PSYCHIATRY, Issue 2009Merete Nordentoft Abstract Aim: To examine the rationale and evidence supporting an early intervention approach in schizophrenia. Methods: A selective literature review was conducted. Results: During the onset of schizophrenia, there is often a significant delay between the emergence of psychotic symptoms and the initiation of treatment. The average duration of untreated psychosis is around 1,2 years. During this period, brain function may continue to deteriorate and social networks can be irreversibly damaged. Studies have consistently linked longer duration of untreated psychosis with poorer outcomes and this relationship holds even after controlling for the potential confounding variable of premorbid functioning. In Norway, the early Treatment and Intervention in PSychosis study demonstrated that duration of untreated psychosis is amenable to intervention with the combination of educational campaigns and specialized early detection units substantially decreasing the period from onset of symptoms to treatment initiation. Furthermore, recent evidence from the randomized controlled OPUS and the Lambeth Early Onset trial studies have linked phase-specific early interventions to improved outcomes spanning symptoms, adherence to treatment, comorbid drug abuse, relapse and readmission. Some benefits persist after cessation of the intervention. Conclusions: Early intervention in schizophrenia is justified to reduce the negative personal and social impact of prolonged periods of untreated symptoms. Furthermore, phase-specific interventions are associated with improved outcomes, at least in the short term. Further research is needed to establish the optimum duration of such programmes.
