Alternative work scheduling for professional social workers.

The authors present some practical evidence that the changing nature of today's work force requires innovative alternatives to traditional scheduling based on the 9 to 5, five-day workweek. They support alternative work scheduling (AWS) as an updated and promising approach. Described is their experience with a two-year AWS pilot project in the Social Work Service of an urban medical center, with their focus upon the processes of negotiating, programming, and implementing the concepts of "flex-time," "compressed workweek," and "job sharing." Informal assessment indicates strongly positive responses from the participating social workers, other members of the health care team, and the consumers of the services.

Metal resistance and accumulation in bacteria.

Recent research on the ecology, physiology and genetics of metal resistance and accumulation in bacteria has significantly increased the basic understanding of microbiology in these areas. Research has clearly demonstrated the versatility of bacteria to cope with toxic metal ions. For example, certain strains of bacteria can efficiently efflux toxic ions such as cadmium, that normally exert an inhibitory effect on bacteria. Some bacteria such as Escherichia coli and Staphylococcus sp. can volatilize mercury via enzymatic transformations. It is also noteworthy that many of these resistance mechanisms are encoded on plasmids or transposons. By expanding the knowledge on metal-resistance and accumulation mechanisms in bacteria, it may be possible to utilize certain strains to recover precious metals such as gold and silver, or alternatively remove toxic metal ions from environments or products where their presence is undesirable.

The outcome of direct current cardioversion (DCC) for the treatment of atrial fibrillation (AF) in a district general hospital in Ireland.

BACKGROUND: Direct current cardioversion (DCC) is a method to control persistent AF, to facilitate a reduction in stroke risk. Although this is a frequently performed procedure, there are no available published data regarding its outcome in an Irish setting. AIMS: To determine the short- and long-term outcome of DCC, factors predicting a successful outcome, and its safety. METHODS: Data relating to each DCC were collected retrospectively from patient notes over a 6.3 year-period, and subsequently entered into a Microsoft Access database before subsequent statistical analysis. RESULTS: Forty-five consecutive unselected patients were identified, in which 59 DCCs were performed. Sinus rhythm (SR) was achieved immediately after DCC in 54/59 (91%) patients. There was a significant positive correlation between patient body weight and the energy level required to achieve SR (p=0.0001). No thromboembolic complications were noted. After a mean follow-up time of 12 +/- 13.7months, 30/45 (67%) had maintained SR. After univariate analysis, a number of important factors predictive of maintenance of SR at follow-up were identified. CONCLUSION: DCC was found to be an effective method for short- and long-term control of AF, without thromboembolic complications, and patients with a favourable long-term outcome after DCC could conceivably be predicted on the basis of a methodical history, careful examination, simple investigations and pharmacological variables.

Radiologic characteristics of primitive neuroectodermal tumors in children.

Radiographic findings are reviewed in 31 children with primitive neural ectodermal tumors seen at the Hospital for Sick Children from 1962 through 1983. Seventeen children were initially evaluated with computed tomography (CT). Ten of these had both CT studies and angiography. The tumors were large, irregular, typically iso- to hyperdense, and showed dense, heterogeneous contrast enhancement. Cysts were present in 65% and calcifications in 71% of cases. The angiographic findings were nonspecific, ranging from avascular to markedly vascular. Although these tumors were usually found in the cerebral hemisphere, particularly the frontal lobes, two cases are included of tumors arising elsewhere: one in the pineal and one in the suprasellar region. Epidemiologic data are reviewed.
