RESUMO
Partnerships are required in health and social care services to meet the increasingly complex needs of vulnerable populations. It is essential to assess these partnerships to ensure partners are supported as they strive to improve their practices. This qualitative study assessed the quality and development of the partnership of an integrated service centre for pregnant women and substance-abusing parents and their young children aged 5 and under. The data were gathered over a period of three years, by means of group and individual interviews. Twenty respondents (practitioners and managers) shared their perceptions of the interagency collaboration at the beginning, the midpoint and the end of the project funding period. Their responses were examined by means of thematic analysis. Conditions facilitating or hindering implementation of the partnership included (a) partners' participation and engagement; (b) nature of the project and its functioning (aspects of governance); (c) partners' joint work with families; and (d) social and political issues. The study highlights critical elements to consider for the development and success of a partnership project. Participants reported a number of barriers to effective collaboration; the main ones, the importance of thorough planning of project implementation, as well as the challenges relating to communication and shared leadership, are discussed.
RESUMO
OBJECTIVES: Segmental sensory nerve conduction velocity (SNCV) was measured from the wrists to the hands and digits in a population of 134 (126 men and 8 women) vibration-exposed shipyard workers following systemic warming using a bicycle ergometer. Results were compared to earlier nerve conduction tests, identical in execution, except that the warming process was segmental and cutaneous. The study was designed to investigate whether SNCVs, which were selectively slow in the fingers after segmental cutaneous (skin surface) warming, would be affected differently by systemic warming. METHODS: Wrist-palm, palm-proximal digit, and digital sensory nerve segments were assessed antidromically by stimulating at the wrist with recording electrodes placed distally. The same subjects were cutaneously warmed in 2001 to >or=31 degrees C and were systemically warmed 28 months later in 2004 by ramped sustained exercise to 100 W for 12 min. Skin temperatures were measured by traditional thermistry and by infrared thermal images taken over the hand and wrist surfaces. RESULTS: When systemic warming was compared to segmental cutaneous warming, SNCVs were increased by 15.1% in the third digit and 20.4% in the fifth digit of the dominant hand. Respective increases in the non-dominant hand were 11.0% and 19.4%. A strong association between increased surface skin temperature and faster SNCV, which had been observed after segmental cutaneous warming, was largely eliminated for both digit and palmar anatomic segments after systemic warming. Significant differences in SNCV between vibration-exposed and non-exposed workers, which had been observed after segmental cutaneous warming, were eliminated after systemic warming. Systemic warming had only a small effect on the wrist-palm (transcarpal) segmental SNCVs. CONCLUSIONS: Reduced SNCV in the digits was observed in vibration-exposed and non-exposed workers. Substituting exercise-induced systemic warming for segmental cutaneous warming significantly increased SNCV in the digits and appeared to reduce differences in SNCV between vibration-exposed and non-exposed workers. These findings persisted despite a substantial time interval between tests, during which the subjects continued to work. There may be more general implications for diagnosing clinical conditions in industrial workers, such as the carpal tunnel syndrome and the hand-arm vibration syndrome.

OBJECTIVES: The purpose of this paper is to assess the overlap and stability of two different case definitions of carpal tunnel syndrome CTS. The analysis considers the association between different case definitions and objective tests (sensory nerve conduction velocities, SNCVs and vibrotactile perception thresholds, TTS), and the natural history of CTS, in the context of two vibration-exposed cohorts. METHODS: Clinical CTS cases were defined in two ways: (1) by the study physician using fixed criteria, and; (2) by questionnaire and hand diagram. SNCV in median and ulnar nerves was measured for digital, transpalmar, and transcarpal segments, and conventionally as from wrist-digit. Skin temperature was assessed as a point measurement by thermistor and regionally by thermal imaging. VTTs were determined at the bilateral fingertips of the third and fifth digits using a tactometer meeting the requirements of ISO 13091-1 (ISO 2001). The subjects were cohorts of shipyard workers in 2001 and 2004, and dental hygienists in 2002 and 2004. RESULTS: Results are reported for 214 shipyard workers in 2001 and 135 in 2004, and for 94 dental hygienists in 2002 and 66 in 2004. In 2001, 50% of shipyard workers were diagnosed as CTS cases by at least one of the diagnostic schemes, but only 20% were positive by both criteria. Among study physician diagnosed cases, 64% were CTS negative in 2001, 76% were negative in 2004, 13% were positive in both years, 22% became negative after being positive, and 11% became positive after being negative. For only study physician diagnosed CTS did VTTs differ between cases differ and non-cases in digit 3; there was no such distinction in digit 5. The dental hygienists had little CTS. CONCLUSION: Clinical case definitions of CTS based on diagrams and self-assessment, and clinical evaluation have limited overlap. Combining clinical criteria to create a more narrow or specific case definition of CTS does not appear to predict SNCV. The natural history of CTS suggests a protean disorder with considerable flux in case status over time.

PURPOSE: Dental hygienists have been found to have high rates of neck and shoulder disorders, but there is very limited information on risk factors associated with those disorders, the level of risk for students, and the relationship of prior work as dental assistants for dental hygiene students. This study examines self-reported and physician-diagnosed neck and shoulder pain. METHODS: A cohort consisting of 27 dental hygiene students with no prior dental occupation experience (mean age 24, 6.2 SD), and 39 dental hygiene students with prior experience as dental assistants (mean age 28, 6.0) and 94 experienced dental hygienists (mean age 46, 8.8) completed a questionnaire on risk factors and self reported pain, and were examined by a physician in reference to upper extremity findings and diagnoses. Analysis included tabular, trend, and logistic regression analysis. RESULTS: There were significant differences for risks, symptoms, and physician findings. Risk factors had a stepwise progression for students, student/assistants, and experienced dental hygienists, including working with a bent neck often or very often (79%, 89%, 96%, respectively, p<.001), static posture (39%, 50%, 63%, p<.001), precise motions (58%, 67%, 90%, p<.001), and repetition (79%, 86%, 98%, p<.001). Neck symptoms were reported by 37%, 43%, and 72%, respectively (p<.001), and 11%, 20%, and 35% for shoulder symptoms (p<.05). Similar patterns were demonstrated in physician findings, particularly for neck disorders (18%, 36%, 50%, p<.01). In regressions, self-reported shoulder pain was significantly associated with working above shoulder height (OR=1.5, CI 1.0-2.4), and neck symptoms with working with a bent neck (OR=2.1, CI 1.3-3.4), with a protective effect from high supervisor support (OR=0.5, CI 0.2-1.0). CONCLUSION: Risk factors and both self-reported and physician-diagnosed neck and shoulder symptoms increase in frequency from students to experienced hygienists, and students have higher prevalence if they are also dental assistants.

BACKGROUND: In a 1988 study of shipyard workers, a progressive association was observed between cumulative exposure to vibration and the vascular and neurological symptoms of the hand-arm vibration syndrome (HAVS). In 2001, after a decade of exposure reduction and ageing of the workforce, a second study at the same site was initiated. METHODS: In 2001, 214 subjects were selected; they represented four current weekly vibration exposure time intervals--0 hr, >0 < 5 hr, > or =5 < 20 hr, > or =20 hr. The 1988 and 2000 cross-sectional populations were compared on the basis of exposure duration and current symptoms. RESULTS: In 2001, the study population was 9.6 years older than the 1988 group. Current weekly exposure hours were similar in the low and medium exposure groups 2001 and 1988, but exposure was reduced by an average of 9.7 hr per week in the highest exposure group (> or =20 hr) in 2001. Symptom severity was regressed polychotomously on estimated exposure (log cumulative hours); the OR was weaker in 2001 than in 1988 for sensorineural symptoms-1.44 [CI 1.04-1.98] versus 2.35 [CI 1.48-3.73]. This was also true for vascular symptoms-1.70 [CI 1.06-2.71] versus 3.99 [CI 2.27-7.01]. Vascular symptoms were more prevalent in the highest lifetime vibration exposure group in 1988 (68.7 vs. 43.2% in 2001); sensorineural symptoms were more prevalent in the least vibration exposed group in 2001 (52.6 vs. 20.7% in 1988). CONCLUSIONS: The prevalence of vascular symptoms associated with cumulative vibratory exposure was significantly greater in 1988, but neurological symptoms were more common at lower exposure levels in 2001. The presumption that reducing exposure duration alone is sufficient, in the absence of change in vibration magnitude, is not supported by the results of this study.
