After chemoradiation for localized non-small-cell lung cancer, surgery and prophylactic cranial irradiation (PCI) have been used as additional therapies. Less than a third of patients develop brain recurrences, or have local recurrence as their sole initial site of recurrence; these are groups that would benefit from PCI or surgery, respectively. Pretreatment identification of patients more likely to benefit from surgery or PCI would be useful. A retrospective analysis of 80 patients was performed to determine prognostic factors for such patterns of failure. Twenty-nine patients were subsequently selected for surgery in a nonrandomized manner. Seventeen patients had isolated local initial recurrence …

The Revised NEO Personality Inventory (NEO-PI-R; Costa & McCrae, 1992b) has been criticized for the absence of validity scales designed to detect response distortion. Recently, validity scales were developed from the items of the NEO-PI-R (Schinka, Kinder, & Kremer, 1997) and several studies have used a variety of methods to test their use. However, it is controversial whether these scales are measuring something that is substantive (such as psychopathology or its absence) or stylistic (which might be effortful distortion or less conscious processes such as lack of insight). In this study, we used a multimethod-multitrait approach to examine the validity …


Sublingual Atropine For Sialorrhea Secondary To Parkinsonism: A Pilot Study, H. Hyson, Andrew Johnson, Mandar Jog Oct 2002

Sublingual Atropine For Sialorrhea Secondary To Parkinsonism: A Pilot Study, H. Hyson, Andrew Johnson, Mandar Jog

Andrew M. Johnson

Sialorrhea is a relatively common symptom in idiopathic Parkinson's disease and related conditions for which most of the accepted treatments are either highly invasive or may cause substantial systemic side effects. This study describes an open-label pilot study of sublingual atropine drops for the treatment of sialorrhea in 7 patients (6 with Parkinson's disease, 1 with progressive supranuclear palsy). Participants demonstrated statistically significant declines in saliva production, both objectively and subjectively. Self-reported drooling severity showed a significant decline between baseline and 180 minutes, t(6) = 3.240 P < 0.025 (eta(2) = 0.636), and between baseline and 1 week, t(6) = 4.583 …

The association between trauma and personality disorders (PDs), while receiving much attention and debate, has not been comprehensively examined for multiple types of trauma and PDs. The authors examined data from a multisite study of four PD groups: schizotypal, borderline (BPD), avoidant, and obsessive-compulsive, and a major depression comparison group. Rates of traumatic exposure to specific types of trauma, age of first trauma onset, and rates of posttraumatic stress disorder are compared. Results indicate that BPD participants reported the highest rate of traumatic exposure (particularly to sexual traumas, including childhood sexual abuse), the highest rate of posttraumatic stress disorder, and …

PURPOSE: Three-dimensional conformal radiation therapy requires the precise definition of the target volume. Its potential benefits could be offset by the inconsistency in target definition by radiation oncologists. In a previous survey of radiation oncologists, a large degree of variation in target volume definition of cervical esophageal cancer was noted for the boost phase of radiotherapy. The present study evaluated whether special training could improve the consistency in target volume definitions. METHODS AND MATERIALS: A pre-training survey was performed to establish baseline values. This was followed by a special one-on-one training session on treatment planning based on the RTOG 94-05 …


Sds-Page And Western Blotting Of Plasmodium Falciparum Proteins, Roland A. Cooper Jun 2002

Sds-Page And Western Blotting Of Plasmodium Falciparum Proteins, Roland A. Cooper

Roland A. Cooper

The Plasmodium spp. parasite was identified as the causative agent of malaria in 1880, and the mosquito was identified as the vector in 1897. Despite subsequent efforts focused on the epidemiology, cell biology, immunology, molecular biology, and clinical manifestations of malaria and the Plasmodium parasite, there is still no licensed vaccine for the prevention of malaria. Physical barriers (bed nets, window screens) and chemical prevention methods (insecticides and mosquito repellents) intended to interfere with the transmission of the disease are not highly effective, and the profile of resistance of the parasite to chemoprophylactic and chemotherapeutic agents is increasing. The dawn …

Objective: The purpose of this study was to compare psychosocial functioning in patients with schizotypal, borderline, avoidant, or obsessive-compulsive personality disorder and patients with major depressive disorder and no personality disorder.

Method: Patients (N=668) were recruited by the four clinical sites of the Collaborative Longitudinal Personality Disorders Study. The carefully diagnosed study groups were compared on an array of domains of psychosocial functioning, as measured by the Longitudinal Interval Follow-Up Evaluation—Baseline Version and the Social Adjustment Scale.

Results: Patients with schizotypal personality disorder and borderline personality disorder were found to have significantly more impairment at work, in social relationships, and …

Objective: This study tested the factor structure of the DSM-IV criteria for borderline personality disorder by using confirmatory methods for the analysis of covariance structures in a large group from a multisite study.

Method: A total of 668 primarily treatment-seeking subjects were reliably assessed for personality disorders by using the Diagnostic Interview for DSM-IV Personality Disorders. Associations among criteria for borderline personality disorder were examined. A confirmatory factor analysis was performed to test diagnosis as a unitary construct and to test an earlier-reported three-factor model comprising disturbed relatedness, behavioral dysregulation, and affective dysregulation. The three-factor model was subsequently tested by …

Monte Carlo Simulations Of Dna Damage From Incorporated Cold Iodine Following Photoelectrically Induced Auger Electron Cascades, V. Moiseenko, S. Karnas, E. Yu, J. Battista Dec 2001

Monte Carlo Simulations Of Dna Damage From Incorporated Cold Iodine Following Photoelectrically Induced Auger Electron Cascades, V. Moiseenko, S. Karnas, E. Yu, J. Battista

Edward Yu

Radiation-induced damage in nucleosomal DNA from Auger electron cascades due to incorporated cold IUdR has been modelled through Monte Carlo simulations. Probabilities of DNA double strand break (DSB) production following a vacancy in the K, L, M and N shells of iodine are estimated. DSB complexity from the base damage accompanying a break was also estimated. Multiple DSB events were analysed for correlated breaks due to nucleosome periodicity. The probability of an Auger cascade causing at least one DSB strongly depended on the shell in which the initial vacancy was produced. This probability was approximately 0.35 for K and L …


Prophylactic Cranial Irradiation Revisited: Cost-Effectiveness And Quality Of Life In Small-Cell Lung Cancer, T. Tai, Edward Yu, Peter Dickof, Glen Beck, Jon Tonita, Tete Ago, David Skarsgard, Marlene Schmidt, Matthew Schmid, John Liem Dec 2001

Prophylactic Cranial Irradiation Revisited: Cost-Effectiveness And Quality Of Life In Small-Cell Lung Cancer, T. Tai, Edward Yu, Peter Dickof, Glen Beck, Jon Tonita, Tete Ago, David Skarsgard, Marlene Schmidt, Matthew Schmid, John Liem

Edward Yu

PURPOSE: To investigate the therapeutic usefulness and cost-effectiveness of prophylactic cranial irradiation (PCI) in patients with limited-stage small-cell lung cancer (SCLC) who had achieved a complete remission. METHODS: A retrospective chart review was undertaken of all patients diagnosed in Saskatchewan with SCLC between 1987 and 1998 inclusive. Patients who achieved a complete remission were divided into two groups, depending on whether they underwent PCI (PCI+ and PCI-, respectively). The quality-of-life-adjusted survival was estimated by the Q-TWiST method (quality time without symptoms and toxicity). The mean incremental costs per month of incremental OS were calculated in a cost-effectiveness analysis. RESULTS: Among …


Changes In The Transmission Of Tuberculosis In New York City From 1990 To 1999, Elvin H. Geng Dec 2001

Changes In The Transmission Of Tuberculosis In New York City From 1990 To 1999, Elvin H. Geng

Elvin H Geng

Background: Over the past decade, there has been a reduction in the incidence of tuberculosis in New York City and in the United States. However, the reduction has been confined mainly to U.S.-born persons. Understanding the reasons for the lack of reduction among non–U.S.-born persons may lead to new strategies for tuberculosis control. Methods: We performed DNA fingerprinting with the IS6110 insertion sequence of the organisms isolated from patients with culture-positive tuberculosis in northern Manhattan from 1990 to 1999. The goal was to identify the strains responsible for multiple infections, presumably through recent transmission (clusters of cases), as well as …

Charles A. Sanislow, Ph.D.

Objective: To test the diagnostic constructs implied by DSM-IV Axis-II personality disorders by examining relationships between different combinations of DSM-IV criteria.

Method: Confirmatory factor analysis was used to test the borderline, schizotypal, avoidant and obsessive-compulsive personality disorder constructs in a large treatment-seeking sample (N=668) from a multisite study. A model based on the three DSM-IV Axis II clusters was also tested. Both models were tested against a unitary ‘generic’ model constructed from four criteria sets combined.

Results: Goodness-of-fit for both the three-cluster and four disorder models was significantly better than the unidimensional model, and the four-disorder model was significantly better …
