Rorschach Depression indices with children and adolescents: concurrent validity findings.

Exner (1983, 1986) developed and recently revised (1990b) a Rorschach Depression Index based on scores from variables in the Comprehensive System. This study evaluated both the original and the revised DEPIs for child and adolescent outpatient (n = 67) and inpatient (n = 99) samples in order to assess the diagnostic utility of these indices. There were no significant relationships between the original form and the revised form of the DEPI and clinical elevations on the Depression scale of the Personality Inventory for Children in the outpatient sample or treatment team diagnostic judgments in the inpatient sample. These findings sound a strong cautionary note for using only Rorschach Depression indices to diagnose depression in children and adolescents.

Radionuclide sinography: diagnosis of lateral sinus thrombosis by dynamic and static brain imaging.

Four patients with lateral sinus thrombosis were studied by radionuclide (RN) dynamic studies and RN static brain scans. Findings included: (a) abrupt termination of RN activity in the midportion of a lateral sinus ("stump sign"); (b) nonvisualization on dynamic, increased visualization on static images ipsilateral to a prominent sinus groove on a plain skull radiograph; and (c) increased activity on static images with nonfilling on angiography. RN demonstration of the "stump sign" is pathognomonic of lateral sinus occlusion; the latter two patterns require radiographic demonstration of an ipsilateral sinus groove or angiography for significance.

Comparison of Tc-99m pyrophosphate and Tc-99m methylene diphosphonate in acute myocardial infarction: concise communication.

This study compared Tc-99m pyrophosphate (PPi) and Tc-99m methylene diphosphonate (MDP) for myocardial infarct imaging in 24 patients with diagnosed acute myocardial infarction. The radiopharmaceuticals were administered randomly and interpreted without knowledge of the sequence used. Twenty-three patients (96%) had positive Tc-99m PPi scintigrams, but only 17 (71%) had a positive Tc-99m MDP study (P less than 0.05). In addition, a comparison of the relative intensity with each agent revealed greater intensity with Tc-99m in 21 cases, equal intensity in two cases, and less intensity in only one case (p less than 0.001). These findings support the superiority of Tc-99m PPi as the agent of choice for myocardial scintigraphy in acute infarction.

Nuclear imaging in urology.

Over the past 10 years nuclear renal imaging has proved to be a valuable diagnostic tool. The information derived from such studies must be correlated with all other imaging procedures now available, i.e., ultrasound and computed tomography. Prior to performing a study, the physician should focus carefully on what information is desired and whether or not it can be acquired. Once that is done, the use of these procedures in urology is extremely helpful and their aid in a given instance is limited only by the creative mind of the physicianuser.

Implications of developmental theories for counseling adolescents in groups.

This paper presents a rationale for the use of group techniques in counseling adolescents, based on selected developmental theories. In addition, it delineates specific practical implications and guidelines for group counselors to consider. Specifically, group selection, group size and composition, and topical content are discussed as they relate to developmental issues during adolescence.
