Reliability, validity and sensitivity to change of neurogenic bowel dysfunction score in patients with spinal cord injury.

STUDY DESIGN: Psychometrics study. OBJECTIVES: The aim of this study is to investigate the validity, reliability and sensitivity to change of neurogenic bowel dysfunction (NBD) score. SETTING: Dokuz Eylül University Faculty of Medicine, Turkey. METHODS: The study included 42 patients with spinal cord injury (SCI). The reliability of NBD score was assessed by test-retest reliability and internal consistency. Cronbach's alpha coefficient was calculated to determine internal consistency. The construct validity was evaluated by exploring correlations between the NBD score and SF-36 scales, patient assessment of impact of NBD on quality of life (QoL) and the physician global assessment (PGA). The Global Rating of Change (GRC) scale was used to assess the change of NBD to investigate the sensitivity of the score to change. RESULTS: Cronbach's alpha coefficient was 0.547. In test-retest reliability analysis, high correlations between total test-retest NBD score and answers of each question were found (r=1.000, P<0.001). NBD score had a strong and significant correlation with PGA (r=0.98, P<0.000) and the impact on QoL (r=0.92, P<0.001). There was a significant negative correlation between NBD score and subscales of SF-36 (P<0.05) except physical functioning, physical role functioning and physical component summary score. There was a significant improvement in NBD scores after treatment (P=0.011). A significant positive correlation was found between GRC scale and change in total NBD score (r=0.821, P=0.007). CONCLUSION: The Turkish version of the NBD score is a valid and reliable instrument and also sensitive to change in patients with SCI.

Bone mineral density in asthmatic patients using low dose inhaled glucocorticosteroids.

Inhaled glucocorticosteroids are clearly beneficial in subjects with moderate or severe asthma since they are well tolerated, reduce symptoms, and improve quality of life. Some studies suggest that inhaled glucocorticosteroids can adversely affect bone mineral density. The aim of this study is to determine the effects of inhaled glucocorticosteroid therapy on bone mineral density in female patients. Forty-five asthmatic female patients (36 premenopousal and 9 postmenopausal) and forty-six healthy control subjects were included in the study. Bone mineral density was measured from lumbar spine (L1-4) and femur (neck, trochanter, and Ward's triangle) by dual energy X-Ray absorptiometry. Age, occupation, menopause and smoking status, alcohol consumption, body mass index, previous fractures, family history of fractures, menstrual history, ooferectomy, number of pregnancies, the duration of lactation, physical activity and calcium intake were questioned according to the European Vertebral Osteoporosis Study Group (EVOS) form. Cumulative inhaled glucocorticosteroid dose was calculated. T score of femoral neck and T score and bone mineral density of Ward's triangle were significantly lower in asthmatic patients compared to control group but no statistically significant correlation was found between the disease duration, inhaled steroid treatment duration, cumulative inhaled dose and annual inhaled steroid dose and bone mineral density measurement. These results suggest that in asthmatic patients using low dose inhaled corticosteroids bone mineral density is lower than in healthy controls but it is still unclear if asthma by itself is a risk factor for osteoporosis.

The droopy shoulder syndrome.

Droopy shoulder syndrome (DSS) is characterized by a depression of the shoulders that stretches the brachial plexus, thus causing pain without any signs of neurological impairment. We describe ten patients with DSS; all had been treated for different diagnoses before. Contrary to previous reports, three patients had unilateral involvement, and five had accompanying disease of the cervical-shoulder region. All patients responded well to conservative treatment in 2-10 weeks. DSS must be kept in mind in the differential diagnosis of pain in the cervical-shoulder region, to prevent unnecessary medication.

An atypical psoriatic spondylitis case, successfully treated with methotrexate.

We present a 45-year-old male patient who was hospitalized with lumbar disc herniation and whose control magnetic resonance imaging (MRI) findings initially suggested brucella spondylitis. Definitive diagnosis, however, indicated psoriatic spondylitis and the patient was successfully treated with methotrexate. A diagnosis of lumbar disc herniation was made in May 1991, during his psoriasis vulgaris treatment. He was hospitalized in August 1994 with a complaint of low-back pain persisting over the last six months despite treatment with analgesics. He was evaluated by clinical, radiological, laboratory and scintigraphic methods, following control MRI findings suggesting infection of vertebral bodies, particularly pointing to brucellosis in addition to disc herniation. A diagnosis of psoriatic spondylitis was finally established and 7.5 mg methotrexate weekly was administered. Significant improvement was obtained of psoriatic skin lesions, low-back pain and MRI findings through a six-month treatment period.
