Two subgroups of hyperactives as adults: correlations of outcome.

This prospective study explored the association of continuing symptoms of the hyperactive syndrome with adult outcome. A fifteen year follow-up compared 61 hyperactive subjects and 41 matched controls. Outcome measures examined included continuing symptoms of the hyperactive syndrome, antisocial behaviour, substance use, and emotional difficulties. Two subgroups of the hyperactive population were identified. Those hyperactive subjects with moderate or severe continuing symptoms were characterized by significant emotional difficulties, alcohol use, and antisocial behaviour. By contrast, hyperactive subjects with none or only mild continuing symptoms at follow-up did not have other difficulties in psychosocial functioning, and were, in addition, similar to the control group in many respects. The importance of continuing symptoms in determining the adult outcome of children with a diagnosis of ADDH is discussed. Accordingly, the need for comprehensive early, and ongoing interventions is emphasized.

A rural child psychiatry day treatment centre: systemic perspective.

The author presents the complexities of directing a DTC (Day Treatment Center) in a rural setting. These complexities are explored from the perspective of system's theory. The various systems contained within the DTC are in dynamic equilibrium with each other as well as with various community groups. Changes in any one system have significant impact on the groups the system impinges on. As an example, the DTC had not functioned well for a period of time prior to the author's arrival. During that period the staff communicated poorly among themselves, resulting in conflicts between the teaching and non-teaching staff. When these conflicts were resolved the well-established incompatibilities and stresses within the system of the non-teaching staff surfaced. In the process of this conflict resolution the DTC was reorganized. New groups were established to access children at primary and secondary levels of medical prevention. Rapport with other systems in the community improved. Consequently, with better communication between groups of staff and with the community, the treatment of the children could be more effective.

Acceleration of tetrazolium reduction by bacteria.

Conditions were assessed which would permit more rapid recognition of bacterial growth than has been previously reported using tetrazolium salts. Microtitration trays were used. 2-(p-Iodophenyl)-3(p-nitrophenyl)-5-phenyltetrazolium chloride is rapidly reduced by respiring cells in tissue homogenates but is more toxic than other tetrazoliums when added to growing bacterial cultures. Phenazine methosulfate (PMS), an intermediate electron carrier, potentiates tetrazolium reduction. Growth was readily detected by the addition of these compounds after 3 to 4 h of incubation in Schaedler broth. The final concentration prior to addition to tray wells was 1.0 mg/ml for 2-(p-iodophenyl)-3(p-nitrophenyl)-5-phenyltetrazolium chloride and 0.06 mg/ml for PMS. Addition of 0.5 to 0.8 g of agar per liter of broth enhanced subsequent tetrazolium reduction.
