RESUMO
ABSTRACT Objective: To determine whether or not Jamaican coaches' knowledge and practices of fluid replacement are on par with that of the National Athletic Association's and the American College of Sports Medicine Standards. Methods: A descriptive survey of 90 high-school track and field coaches in Jamaica was conducted. Coaches were given a 29-item survey questionnaire which adapted the content from previous surveys and also based on the National Athletic Trainers' Association guidelines for fluid replacement and information sources of fluid replacement. A pass score of 80% was employed. Results: Approximately 26.6% of participants passed the knowledge-based assessment with the minimum requirement of 80% and 73.4% of participants had an unacceptable level of knowledge about fluid replacement and hydration. Only 26 (28.9%) coaches received training in fluid replacement therapy. Most of them therefore relied on reading materials ranging from magazines to journals, or learnt it on the job from other coaches. Conclusion: Findings suggest that the level of knowledge in Jamaican track and field high-school coaches about fluid replacement and hydration is very poor. However, their attitudes towards fluid replacement and hydration are very good, and this will facilitate their acceptance and adoption of correct fluid replacement guidelines. Tapping into this positive attitude and implementing workshops, seminars and onsite promotion should improve the coaches' knowledge significantly.
RESUMO
OBJECTIVE: To characterize geographic variation in neonatal intensive care unit (NICU) admission rates across the entire birth cohort and evaluate the relationship between regional bed supply and NICU admission rates. STUDY DESIGN: This was a population-based, cross-sectional study. 2013 US birth certificate and 2012 American Hospital Association data were used to assign newborns and NICU beds to neonatal intensive care regions. Descriptive statistics of admission rates were calculated across neonatal intensive care regions. Multilevel logistic regression was used to examine the relationship between bed supply and individual odds of admission, with adjustment for maternal and newborn characteristics. RESULTS: Among 3 304 364 study newborns, the NICU admission rate was 7.2 per 100 births and varied across regions for all birth weight categories. IQRs in admission rates were 84.5-93.2 per 100 births for 500-1499 g, 35.3-46.1 for 1500-2499 g, and 3.5-5.5 for ≥2500 g. Adjusted odds of admission for newborns of very low birth weight were unrelated to regional bed supply; however, newborns ≥2500 g in regions with the highest NICU bed supply were significantly more likely to be admitted to a NICU than those in regions with the lowest (aOR 1.20 [1.03-1.40]). CONCLUSIONS: There is persistent underuse of NICU care for newborns of very low birth weight that is not associated with regional bed supply. Among larger newborns, we find evidence of supply-sensitive care, raising concerns about the potential overuse of expensive and unnecessary care. Rather than improving access to needed care, NICU expansion may instead further deregionalize neonatal care, exacerbating underuse.

BACKGROUND: Osteogenesis imperfecta, also known as 'brittle bone disease', is a genetic connective tissue disease. It is characterized by bone fragility and osteopenia (low bone density). In this case, a 57-year old female presented to the University Hospital of the West Indies (UHWI), Physical Medicine and Rehabilitation Clinic with left low back pain rated 6/10 on the numeric rating scale (NRS). Clinically, the patient had sacroiliac joint mediated pain although X-rays did not show the sacroiliac joint changes. Fluoroscopy-guided left sacroiliac joint steroid injection was done. METHODS: Numeric rating scale and Oswestry Disability Index (ODI) questionnaire were used to evaluate outcome. This was completed at baseline, one week follow-up and at eight weeks post fluoroscopy-guided sacroiliac joint steroid injection. RESULTS: Numeric rating scale improved from 6/10 before the procedure to 0/10 post procedure, and ODI questionnaire score improved from a moderate disability score of 40% to a minimal disability score of 13%. Up to eight weeks, the NRS was 0/10 and ODI remained at minimal disability of 15%. CONCLUSION: Fluoroscopy-guided sacroiliac joint injection is a known diagnostic and treatment method for sacroiliac joint mediated pain. To our knowledge, this is the first case published on the use of fluoroscopy-guided sacroiliac joint steroid injection in the treatment of sacroiliac joint mediated low back pain in a patient with osteogenesis imperfecta.
RESUMO
The pervasive effect of HIV infection on the immune system requires that the clinician be alert to the variety of immunologic abnormalities that can result from this disease. The tests described in this section provide guidelines for testing the HIV-infected child. Additional information on immunologic evaluations in the child with indeterminate HIV infection status can be found in the article on ambulatory care.

The effect of intravenously administered immune globulin (IVIG) on patients with cystic fibrosis with an acute exacerbation of pulmonary infection was evaluated in a double-blind study. Patients at least 12 years of age, with chronic respiratory tract colonization with Pseudomonas aeruginosa and hospitalized with a reduction in pulmonary function, were randomly assigned to receive 20% dextrose (control subjects: n = 8) or 100 mg/kg IVIG (Gamimune) (experimental subjects: n = 8) on days 1, 2, and 3; all patients received intravenous antibiotics and chest physiotherapy. There were no differences between groups on admission; patients had moderate to severe disease as measured by Shwachman-Kulczycki scores and pulmonary function tests. Both groups improved clinically. The IVIG treatment was associated with significant increases in forced vital capacity and forced expiratory volume in 1 second (p less than 0.01) and with greater percent improvement in forced expiratory volume and forced expiratory flow (25% to 75%) (p less than 0.05). There was no effect on length of hospitalization (18.3 +/- 11.9 days control vs 17.6 +/- 6.5 experimental). The C3 level was decreased at discharge in IVIG-treated patients; circulating immune complex levels were unchanged. One patient in each group experienced side effects. There were no differences on follow-up at 6 weeks. We conclude that IVIG infusion early in treatment for pulmonary exacerbations in cystic fibrosis patients with moderate to severe disease may be associated with greater improvement in pulmonary function than standard treatment alone.
