Organizational Guidelines for Dual Disorders Programs

Dual disorders—combined severe mental disorders and substance use disorders—were barely recognized two decades ago. As a result of the high prevalence and serious consequences of these disorders, they have received considerable attention over the last two decades. Knowledge has accumulated about dual disorders and their treatment, and treatment providers may now consider numerous options for clinical interventions and program designs. In this article, we offer guidelines concerning these options. We review the current knowledge about dual disorders and the results of recent research on the assessment and treatment of these disorders. We present treatment principles, recommendations on the components and organization of dual disorders programs, and suggestions for dealing with clinical issues that remain controversial. We conclude with comments on the demands of the managed care environment and the heightened importance of continued research in this area.     

Peripheral pulmonary lesions: ultrasonography and ultrasonically guided aspiration biopsy

Twenty-five patients, each of whom had peripheral intrathoracic lesions that were smaller than 5.0 X 5.0 cm in size and not diagnosed by conventional methods, underwent real-time sonography and ultrasonically guided aspiration biopsy. The lesions included 18 nodules, two infiltrates, and five cavitary lesions. Sonography showed homogeneous hypoechoic or isoechoic density with well-defined margins in 16 of the nodules, and heterogeneous echogenicity with irregular margins in infiltrates. The cavitary lesions showed a hyperechoic ring with a central sonolucent area. Biopsy specimens were successfully obtained by percutaneous aspiration under ultrasound guidance in 24 (96%) of the patients, and a positive diagnosis was established in 21 (84%) by cytology and/or histology. All 17 malignant lesions were diagnosed by aspiration biopsy, while only four of seven benign lesions were diagnosed by this method. Two patients (8%) experienced minimal pneumothorax after aspiration biopsy. We conclude that real-time sonography, including ultrasonically guided aspiration biopsy, is a useful and safe method for examination of peripheral intrathoracic lesions and has a high diagnostic yield.     

Implementing evidence-based practices for people with severe mental illness

Persons with severe mental illnesses (SMI) often lack access to effective treatments. The authors describe the Implementing Evidence-Based Practices (EBPs) Project, designed to increase access for people with SMI to empirically supported interventions. The EBP Project aims to improve access through development of standardized implementation packages, created in collaboration with different stakeholders, including clinicians, consumers, family members, clinical supervisors, program leaders, and mental health authorities. The background and philosophy of the EBP Project are described, including the six EBPs identified for initial package development: collaborative psychopharmacology, assertive community treatment, family psychoeducation, supported employment, illness management and recovery skills, and integrated dual disorders treatment. The components of the implementation packages are described as well as the planned phases of the project. Improving access to EBPs for consumers with SMI may enhance outcomes in a cost-effective manner, helping them pursue their personal recovery goals with the support of professionals, family, and friends.     

Cryptorchidism: A general surgical perspective

Background The treatment of cryptorchidism has changed, with surgery now advocated before the age of two years. Delayed treatment affects fertility, malignant potential and psychological stress. Aims To assess the pattern of referral of cryptorchid patients to a surgical clinic, management and follow-up. Methods A four-year review of 114 cryptorchid patients examined age at presentation, waiting time, timing of surgery and length of follow-up. Results The mean age at presentation to the surgical clinic was 6.7 years (neonatal to 71). The mean age at orchidopexy was 5.6 years. Seventy per cent had a surgical procedure within eight weeks of presentation to a surgeon. Seven per cent were kept under surveillance until a maximum age of three years before orchidopexy was considered. Only 29% proceeded to surgery before the age of two. Seventeen were referred to a paediatric urology unit for further management. Conclusions Orchidopexy seems prudent between one and two years of age. Only one-quarter of patients underwent early orchidopexy. It is vital that it is detected early, by paediatricians at birth or the general practitioners (GPs) at the six-week check up. Prompt referral to a surgeon with a paediatric interest is essential in order to permit surveillance or surgery.     

Assessment of enduring deficit and negative symptom subtypes in schizophrenia.

The clinical importance of subtypes based on enduring deficit or negative symptoms was examined in a group of schizophrenic patients who were assessed twice over a 1-year period. Subgroups of patients with high levels of enduring negative or deficit symptoms, based on the Scale for the Assessment of Negative Symptoms and the Quality of Life Scale, had a poorer prognosis and were consistently worse in social adjustment, quality of life, and thought disorder over the year than were patients with less severe negative symptoms. Subtypes based on Andreasen's negative schizophrenia classification and on enduring thought disorder were only weakly related to other symptoms and social adjustment. Social-skill deficits were weakly related to the enduring negative symptom subtype and Andreasen's negative schizophrenia. The results suggest that enduring negative and deficit symptoms may be associated with a poor outcome in schizophrenia, including more severe positive symptoms, lower levels of social adjustment, and a poorer quality of life.     

Hallucinations in schizophrenia

The prevalence of different types of hallucinations and their clinical correlates were examined in 117 DSM-III-R schizophrenic or schizoaffective disorder patients. Auditory hallucinations were by far the most common, followed by visual hallucinations, and then by tactile and olfactory or gustatory hallucinations. Auditory hallucinations were associated with an earlier age of first hospitalization among the schizophrenics. Global severity of the illness for schizophrenics was related to the presence of visual hallucinations, but not other types of hallucinations. Tactile and olfactory or gustatory hallucinations were strongly correlated with each other and with the severity of delusions for both schizophrenic and schizoaffective patients. The results suggest that important clinical differences exist between patients with different types of hallucinations, and that these clinical variables need to be controlled for in cross-cultural studies of hallucinations.     

The effects of neuroleptic drugs on the social interactions of hospitalized psychotic patients

The frequency of social interactions emitted by two groups of hospitalized psychotic patients was studied with a time sampling procedure during lunch periods in the ward dayroom. One group was treated with neuroleptic medication upon admission to the ward, and the other group was medicated after a 2- to 3-week washout period. The data suggest that the principle effect of the medication is to produce a transient depression in social interaction frequency which returns to baseline with continued drug treatment. The results are supportive of previous research which indicated that the major impact of pharmacotherapy is on activity rather than social behaviors, and highlights the utility of including baseline measures to ensure adequate drug vs. control comparisons.
