The impact of task type, group size and proximity on group support system
148 p.As organizations flatten their hierarchy and globalize, there is an increasing possibility that members of a work team would be physically distributed. In an increasingly competitive business environment, there is a need to make decisions in real time and to allow the team to work together over a period of time. There is growing interest in the use of group support systems to support such spatially separated teams to meet synchronously and asynchronously. However, there is still apprehension about this use of GSS, as the body of research in DGSS still does not paint a very clear picture, especially about how DGSS can support different group tasks, group sizes, and promote team building and preserve decision quality at the same time.ACCOUNTANC

Ischemic Ventricular Tachycardia Presenting as a Narrow Complex Tachycardia
This report describes a patient presenting with a narrow complex tachycardia in the context of prior myocardial infarction and impaired ventricular function. Electrophysiological studies confirmed ventricular tachycardia and activation and entrainment mapping demonstrated a critical isthmus within an area of scar involving the His-Purkinje system accounting for the narrow QRS morphology. This very rare case shares some similarities with upper septal ventricular tachycardia seen in patients with structurally normal hearts, but to our knowledge has not been seen previously in patients with ischemic heart disease
Treatment of nasopharyngeal carcinoma using intensity-modulated radiotherapy - the national cancer centre Singapore experience
Purpose:
The aim of this study was to determine the efficacy and acute toxicity of our early experience with treating nasopharyngeal carcinoma (NPC) patients with intensity-modulated radiotherapy (IMRT).
Methods and materials:
A review was conducted on case records of 195 patients with histologically proven, nonmetastatic NPC treated with IMRT between 2002 and 2005. MRI of the head and neck was fused with CT simulation images. All plans had target volumes at three dose levels, with a prescribed dose of 70 Gy to the gross disease, in 2.0–2.12 Gy/fraction over 33–35 fractions. Cisplatin-based chemotherapy was offered to Stage III/IV patients.
Results:
Median patient age was 52 years, and 69% were male. Median follow-up was 36.5 months. One hundred and twenty-three patients had Stage III/IV disease (63%); 50 (26%) had T4 disease. One hundred and eighty-eight (96%) had complete response; 7 (4%) had partial response. Of the complete responders, 10 (5.3%) had local recurrence, giving a 3-year local recurrence-free survival estimate of 93.1% and a 3-year disease-free survival of 82.1%. Fifty-one patients (26%) had at least one Grade 3 toxicity.
Conclusions:
Results from our series are comparable to those reported by other centers. Acute toxicity is common. Local failure or persistent disease, especially in patients with bulky T4 disease, are issues that must be addressed in future trials
