Physical examinations in inner-city preschools.

This paper describes the physical examination program started in March 1974 and carried out by the Anacostia Headstart Program in Washington DC. Annual totals of 362, 274, and 458 preschool children were examined in 16 schools during the 1973-1974, 1974-1975, and 1975-1976 school years, respectively. For these years, 8, 9, and 12 percent, respectively, had heart murmurs. The rates for abdominal hernias were higher, 11, 17, and 16 percent, respectively. Eczema was also a common problem. Parents had easy access to counseling from health professionals who worked in the program.

The influence of pH and external K+ concentration on caesium toxicity and accumulation in Escherichia coli and Bacillus subtilis.

Toxicity screening of Escherichia coli NCIB 9484 and Bacillus subtilis 007, NCIB 168 and NCIB 1650 has shown Cs+ to be the most toxic Group 1 metal cation. However, toxicity and accumulation of Cs+ by the bacteria was affected by two main external factors; pH and the presence of other monovalent cations, particularly K+. Over the pH range 6-9 both E. coli and B. subtilis showed increasing sensitivity towards caesium as the pH was raised. The presence of K+ and Na+ in the laboratory media used lowered caesium toxicity and lowered accumulation of the metal. In order to assess accurately Cs+ toxicity towards the bacterial strains it was therefore necessary to define the K+:Cs+ ratio in the external medium. The minimum inhibitory K+:Cs+ concentration ratio for the Bacillus strains tested was in the range 1:2-1:3 while E. coli had a minimum inhibitory K+:Cs+ concentration ratio of 1:6.

Identification and management of pregnancy-related low back pain.

Back pain is a common complaint of women during pregnancy. It is frequently dismissed as trivial and inevitable. This article gives an overview of recent research on pregnancy-related back pain that documents the impact of this pain on women's lives, during and beyond the childbearing year. It argues for a more active approach to the prevention and management of back pain during pregnancy. Two common back pain types, lumbar pain and posterior pelvic pain, are described and basic management techniques for the woman and her primary caregiver are suggested. Red flag findings that necessitate specialist referral are also highlighted, as are suggestions for further research.

From student to therapist: exploring the first year of practice.

OBJECTIVES: The transition from classroom to clinical practice challenges many health professional students. This study used a phenomenological approach to explore the lived experience of rehabilitation students during their final placement and first year of practice. METHOD: Students (n = 6) in occupational therapy and physical therapy wrote reflective journals every 2 weeks during their final fieldwork placement and first year of practice. The researchers independently analyzed the journals for common themes. An independent peer completed a blind analysis of two journals. Data were also compared with published first-person accounts of novice practitioners. RESULTS: The lived experience of the first year of practice included four consecutive stages: Transition, Euphoria and Angst, Reality of Practice, and Adaptation. Themes from the journals included great expectations, competence, politics, shock, education, and strategies. CONCLUSION: Recognizing the stages in the process of transition from student to therapist may assist in educational curriculum development and clinical support and supervision for new graduates. Educators need to continue to make education practice relevant while maintaining a theoretical perspective.

Monopolies, Maricopa, and marketing: a case study.

The development of preferred provider organizations in recent years has caused significant concerns about the antitrust implications of these new organizational arrangements among healthcare providers. The potential of being accused of price-fixing, monopolistic, or anti-competitive activity has concerned many health professionals involved in establishing PPOs. This article presents the nature of some of the antitrust arguments and a few representative cases demonstrating various rulings about the anti-competitive elements present or absent from various PPO arrangements. In addition, selected state and federal legislation concerning PPOs is discussed. In addition to understanding the antitrust issues involved in PPOs, establishing a PPO also requires the active involvement of the various key players in determining structural and pricing arrangements. The case study presented here demonstrates the use of marketing principles which emphasize the importance of participation and communication in decision making with physicians in the formation of a PPO.
