Acute rib fracture pain in CF

Osteoporosis Is Associated with Deteriorating Clinical Status in Adults with Cystic Fibrosis

BACKGROUND

Cystic fibrosis (CF) patients are in increased risk of osteoporosis. We aimed to determine the osteoporosis prevalence in an adult CF cohort and investigate calcium metabolic parameters and clinical status' association with bone mineral density evaluated by dual X-ray absorptiometry scan.

METHODS

We performed a cross section database study of adults at a tertiary CF Center. Z scores were applied for patients < 50 years of age and T scores for patients > 50 years of age.

RESULTS

One hundred twenty-five patients were included. Compared to nonosteoporotic patients, osteoporotic patients (15%) had significantly lower percent predicted forced expiratory volume in 1 second (ppFEV1), lower body mass index, higher frequency of CF-related diabetes and chronic lung infection, and higher high-sensitive C-reactive protein and glycated hemoglobin levels. Vitamin D was not associated with any outcome. In multivariate analyses, only ppFEV1 and female gender were independently associated with Z scores.

CONCLUSIONS

Osteoporosis in CF occurs with deteriorating clinical status while the role of calcium metabolism seems minor. Gender specific and dysglycemic impact on bone status should be investigated further.

Physiotherapy management of cystic fibrosis

For many years physiotherapy for cystic fibrosis (CF) was synonymous with a daily routine of postural drainage and percussion. Improved longevity and a desire for independence, together with a clearer understanding of the pathophysiology of the disease, has led to the development of many airway clearance techniques. The contribution of ‘chest’ physiotherapy remained unchallenged until recent times when lack of robust evidence and the presentation of asymptomic infants and adults led some physiotherapists to question this traditional approach. As survival increases into the fourth and fifth decade unique complications have evolved and physiotherapy management is challenged with nonrespiratory aspects of treatment. This review will consider the evidence for, and current practice of airway clearance, the value of exercise and the emerging problems of musculoskeletal complications and incontinence.

Analgesic effect of nasal salmon calcitonin during the early post-fracture period of the distal radius fracture

OBJECTIVES

To investigate the analgesic effect of nasal salmon calcitonin on the post-fracture period of distal radius fracture.

METHODS

In this prospective randomized double-blind study, forty-one postmenopausal women with a recent distal radius fracture treated conservatively were randomly assigned to receive either 200 IU of intranasal salmon calcitonin or placebo daily for 3 months following fracture. The assessment of the patient's pain was recorded using the Visual Analogue Scale (VAS).

RESULTS

The average age of the calcitonin group was 67.11 (SD, ±8.68) years and 64.91 (SD, ±7.48) of the placebo group. In the calcitonin group, the mean VAS score improved from 4.05 to 0.53 while in the placebo group from 3.36 to 0.32. A higher decrease of VAS score during the first post-fracture period was observed in the calcitonin group.

CONCLUSIONS

In the study, there is a statistically significant calcitonin mediated analgesic effect in the immediate post fracture period (at 10 days) when compared to placebo group. These results are in accordance with literature referring to the analgesic effect of calcitonin in the acute osteoporotic vertebral compression fracture. Thus calcitonin administration could be recommended to a short term course in acute osteoporotic conservatively treated distal radius fractures.

Intravenous zoledronate improves bone density in adults with cystic fibrosis (CF)

OBJECTIVE

Reduced bone mineral density (BMD) and increased rates of atraumatic fracture are observed in cystic fibrosis (CF) patients, causing increasing morbidity as this population ages. The study aimed to assess the safety, tolerability and effect on BMD of intravenous zoledronate in adults with CF and osteopaenia.

DESIGN

Randomized, double-blind, placebo-controlled clinical trial.

SETTING

Adult CF outpatient clinics at two hospitals.

PATIENTS

Twenty-two non-transplanted CF patients aged > or = 18 years with a bone densitometry T-score of < -1.5 at one of three sites (lumbar spine, femoral neck, distal forearm) were studied. Participants were randomized to receive either 2 mg zoledronate i.v. (n = 10) or normal saline (placebo, n = 12) every 3 months for 2 years (8 infusions). All participants received calcium and vitamin D supplements twice daily.

MEASUREMENTS

Percentage change in areal BMD from baseline.

RESULTS

Lumbar spine BMD increased from baseline more with zoledronate than placebo at 6 months (5.35 +/- 0.76 vs. 1.19 +/- 1.20%, P = 0.012), 12 months (6.6 +/- 1.5 vs. 0.35 +/- 1.55%, P = 0.011) and 24 months (6.14 +/- 1.86 vs. 0.44 +/- 0.10, P = 0.021). Femoral neck BMD increased more after zoledronate than placebo at 6 months (3.2 +/- 1.6 vs.-1.43 +/- 0.43%, P = 0.019), 12 months (4.12 +/- 1.8 vs.-1.59 +/- 1.4%, P = 0.024) and 24 months (4.23 +/- 1.3 vs.-2.5 +/- 1.41%, P = 0.0028). Forearm BMD did not change. Zoledronate was associated with flu-like and musculoskeletal side effects, particularly after the first infusion. There were no fractures in either group.

CONCLUSION

Intravenous zoledronate was significantly more effective than placebo for increasing BMD in adults with CF and osteopaenia, but side effects limited its tolerability.
