A problem-solving approach to group psychotherapy in the inpatient milieu

Because of the trend toward a marked decrease in length of psychiatric hospitalization, clinicians need to improve the organization of the therapeutic milieu so that behavioral changes can be effected more rapidly. A university general psychiatric unit has adapted a problem-solving model that integrates groups and activities so that each one focuses on complementary behavioral objectives for each patient with the aim of effecting more rapid behavior change. The stages of the model are incorporated in a weekly sequence that begins with a goal-setting group. In a series of subsequent groups, each patient tries to develop and implement a solution to the problem identified that week. At the end of each week, patients participate in a goal review group, with feedback from staff and peers and self-reinforcement. The model can be used with a diverse patient population without interfering with each patient's individual psychotherapy or pharmacotherapy.

Comparison of BIOGRAM and commercial microdilution antimicrobial susceptibility test systems.

The BIOGRAM (Difco Laboratories, Detroit, Mich.) system, which is designed to calculate MICs from disk diffusion zone diameters, was compared with two commercial microdilution antimicrobial susceptibility systems. A total of 111 clinical isolates were evaluated with each test system. Six additional isolates were tested in a comparison between BIOGRAM and Sceptor (Johnston Laboratories, Inc. Towson, Md.) systems. BIOGRAM demonstrated an overall correlation with the Sceptor microdilution method of 95.7% for 1,287 organism-antimicrobial susceptibility combinations. The BIOGRAM and UniScept (Analytab Products, Inc., Plainview, N.Y.) systems were in agreement in 90.3% of 1,048 organism-antimicrobial susceptibility combinations tested. All methicillin-resistant staphylococci were detected by the standard disk agar diffusion method used with the BIOGRAM system. The BIOGRAM system provides an acceptable alternative to these commercial systems for the determination of quantitative susceptibility.     

Linkage of chromosome 13q32 to schizophrenia in a large veterans affairs cooperative study sample

Several prior reports have suggested that chromosomal region 13q32 may harbor a schizophrenia susceptibility gene. In an attempt to replicate this finding, we assessed linkage between chromosome 13 markers and schizophrenia in 166 families, each with two or more affected members. The families, assembled from multiple centers by the Department of Veterans Affairs Cooperative Studies Program, included 392 sampled affected subjects and 216 affected sib pairs. By DSM-III-R criteria, 360 subjects (91.8%) had a diagnosis of schizophrenia and 32 (8.2%) were classified as schizoaffective disorder, depressed. The families had mixed ethnic backgrounds. The majority were northern European-American families (n = 62, 37%), but a substantial proportion were African-American kindreds (n = 60, 36%). Chromosome 13 markers, spaced at intervals of approximately 10 cM over the entire chromosome and 2-5 cM for the 13q32 region were genotyped and the data analyzed using semi-parametric affected only linkage analysis. For the combined sample (with race broadly defined and schizophrenia narrowly defined) the maximum LOD score was 1.43 (Z-score of 2.57; P = 0.01) at 79.0 cM between markers D13S1241 (76.3 cM) and D13S159 (79.5 cM). Both ethnic groups showed a peak in this region. The peak is within 3 cM of the peak reported by Brzustowicz et al. [1999: Am J Hum Genet 65:1096-1103].     

Liposome-mediated gene transfer to fetal human ventral mesencephalic explant cultures

To clarify how Abeta deposits induce secondary tauopathy, the presence of phosphorylated tau, glycogen synthase kinase 3alpha (GSK3alpha), GSK3beta, cyclin-dependent kinase 5 (CDK5), mitogen-activated protein kinase (MAPK) and fyn were examined in the Tg2576 brain showing substantial brain Abeta amyloidosis and behavioral abnormalities. Phosphorylated tau at Ser199, Thr231/Ser235, Ser396 and Ser413 accumulated in the dystrophic neurites of senile plaques. The major kinase for tau phosphorylation was GSK3beta. Smaller contributions of GSK3alpha, CDK5 and MAPK were suggested. Thus, brain Abeta amyloidosis has a potential role in the induction of tauopathy leading to the mental disturbances of Alzheimer's disease.     

PTSD and Comorbid Psychotic Disorder: Comparison with Veterans Diagnosed with PTSD or Psychotic Disorder

Symptoms of posttraumatic stress disorder (PTSD), psychosis, general psychopathology, role functioning, violence potential, and cognitive and emotional aspects of psychotic states were compared in three groups of veterans. Groups were defined on the basis of their DSM-IV diagnoses: Psychotic disorder and war-related PTSD, war-related PTSD without psychotic symptoms, and psychotic disorder without PTSD. Veterans with PTSD and a comorbid psychotic disorder showed significantly higher levels of positive symptoms of psychosis, general psychopathology, paranoia, and violent thoughts, feelings, and behaviors than the other two groups. These data show that patients with comorbid PTSD and psychotic disorder show levels of cognitive, emotional, and behavioral disturbance that far exceed the levels of disturbance seen in patients with PTSD without psychosis or in patients with psychotic disorder.
