Advanced cancer patients experience stress and are at risk for developing psychological problems. Early diagnosis and suitable intervention are very important for their quality of life and compliance with chemotherapy. The Hospital Anxiety and Depression Scale (HADS) is one of the most commonly used mood scales; however, HADS has not been validated for use with cancer patients undergoing chemotherapy. The purpose of this study was to validate HADS as a screening tool for psychological distress among cancer patients undergoing chemotherapy. We also identified possible factors contributing to psychological distress and explored the development of original screening tools. Fifty subjects agreed to complete HADS and consult with psychiatric specialists. Possible contributing factors to psychological distress were identified by HADS and logistic regression analysis. The mean score for patients with psychological distress was 20.0 ± 8.93, and for patients without distress was 9.67 ± 6.11; scores for patients with psychological distress were significantly higher. The optimal cutoff point of psychological distress appeared to be 17. This cutoff point was associated with 72.7% sensitivity and 82.1% specificity. The factor “recurrent cancer” (p=0.043) had an odds ratio of 7.24 (1.21-61.2). We verified that HADS is a useful screening tool for cancer patients undergoing chemotherapy. The factor “recurrent cancer” was shown to contribute to psychological distress. Palliat Care Res 2011; 6(2): 150-157

We report a pediatric baseball player having both a fracture of the posterior ring apophysis and spondylolysis. He was presented to a primary care physician complaining of back pain and leg pain. Despite conservative treatment for 3 months, the pain did not subside. He was referred to our clinic, and surgical intervention was carried out. First, a bony fragment of the caudal L5 apophyseal ring was removed following fenestration at the L5-S interlaminal space, bilaterally: and decompression of the bilateral S1 nerve roots was confirmed. Next, pseudoarthrosis of the L5 pars was refreshed and pedicle screws were inserted bilaterally. A v-shaped rod was inserted beneath the L5 spinous process, which stabilized the pars defects. After the surgery, back pain and leg pain completely disappeared. In conclusion, the v-rod technique is appropriate for the spondylolysis direct repair surgery, especially, in case the loose lamina would have a partial laminotomy.

OBJECTIVEThe aim of this study was to establish reference concentrations of urinary strontium by inductively coupled plasma atomic emission spectrometry (ICP-AES).

METHODSFor the determination of strontium, urine samples were collected from healthy Japanese (n=146; 115 males, 31 females; mean age, 33±9 years; age range, 18 to 58 years). The urine samples stored at or below -20°C were thawed with incubation at 40°C for 30 min and sediments were dissolved by vigorous shakings. Then, the samples were centrifuged at 3000 g for 5 min, and the supernatant was directly aspired into a P-5200-3600/1200 ICP-AES system from Hitachi Ltd., Tokyo, Japan.

RESULTSA steeper increase in the S/N ratio and a good effective linearity of the calibration line was obtained at 407.771 nm in the range of 0-300 μg/L strontium standard solution. Urine samples having the same background signal as that of 18 MΩ cm ultrapure blank water, a good correspondence of the single peak pattern of the spectra, accuracy and precision of spike recovery were also confirmed. Urinary strontium concentrations showed a log-normal distribution and a geometric mean concentration of 143.9 μg/L, with 5-95% confidential interval of 40.9-505.8 μg/L.

CONCLUSIONThe results of this study will be useful as guidelines for the biological monitoring of strontium in normal subjects and in individuals therapeutically or environmentally exposed to strontium.
