Expression of TRAIL, IP-10, and CRP in children with suspected COVID-19 and real-life impact of a computational signature on clinical decision-making: a prospective cohort study.

PURPOSE: We evaluated the host-response marker score "BV" and its components TRAIL, IP-10, and CRP in SARS-CoV-2 positive children, and estimated the potential impact on clinical decision-making. METHODS: We prospectively analyzed levels of TRAIL, IP-10, CRP, and the BV score, in children with suspected COVID-19. Classification of infectious etiology was performed by an expert panel. We used a 5-point-questionnaire to evaluate the intention to treat with antibiotics before and after receiving test results. RESULTS: We screened 111 children, of whom 6 (5.4%) were positive for SARS-CoV-2. A total of 53 children were included for the exploratory analysis. Median age was 3.1 years (interquartile range [IQR] 1.3-4.3), and 54.7% (n = 29) were girls. A viral and a bacterial biomarker pattern was found in 27/53 (50.9%) and 15/53 (28.3%), respectively. BV scores differed between COVID-19, children with other viral infections, and children with bacterial infections (medians 29.5 vs. 9 vs. 66; p = 0.0006). Similarly, median TRAIL levels were different (65.5 vs. 110 vs. 78; p = 0.037). We found no differences in IP-10 levels (555 vs. 504 vs. 285; p = 0.22). We found a concordance between physicians' "unlikely intention to treat" children with a viral test result in most cases (n = 19/24, 79.2%). When physicians expressed a "likely intention to treat" (n = 15), BV test revealed 5 bacterial, viral, and equivocal scores each. Antibiotics were withheld in three cases (20%). Overall, 27/42 (64%) of pediatricians appraised the BV test positively, and considered it helpful in clinical practice. CONCLUSION: Host-response based categorization of infectious diseases might help to overcome diagnostic uncertainty, support clinical decision-making and reduce unnecessary antibiotic treatment.

[Progressive muscle relaxation in postoperative pain therapy]. / Progressive Muskelrelaxation in der postoperativen Schmerztherapie.

BACKGROUND: Early and optimal treatment of postoperative pain based on a multimodal treatment concept is very important so that subsequent chronification can be avoided. OBJECTIVES: This study investigated the influence of progressive muscle relaxation on the sensation of pain and the need for analgesics after orthopedic interventions. MATERIALS AND METHODS: This nonrandomized pilot study tested 104 patients in the Clinic of Orthopedics at the Saarland University Medical Center in Homburg, Germany. The patients underwent total endoprosthesis (TEP) of the or the knee or spine surgery (laminectomy), and they had the option of choosing to use the technique of progressive muscle relaxation. All patients completed a questionnaire on the first, fourth, and ninth postoperative day. Data were collected on the maximum and minimum intensity of pain, duration of strong pain, length of hospital stay, and use of pain medication. These were compared by means of t tests for the group with progressive muscle relaxation and the group without progressive muscle relaxation. RESULTS: No significant difference was observed between the two groups regarding pain sensation analgesic dosage. There was a tendency for the length of hospital stay to be shorter in the group with progressive muscle relaxation. CONCLUSION: The positive effect of progressive muscle relaxation cannot be confirmed on the basis of the study data. Owing to the varying study design and implementation as well as the inclusion of heterogeneous patient groups, no conclusion can be drawn at present regarding the effectiveness of progressive muscle relaxation in common practice; therefore, further research is necessary.

Photobiomodulation therapy in breast cancer-related lymphedema: a randomized placebo-controlled trial.

BACKGROUND: The aim of our study was to examine the effects of photobiomodulation therapy (PBMT) in the treatment of breast cancer-related lymphedema using a compactly designed treatment regime consisting of eight therapy sessions in combination with a cluster laser device covering a total area size of 78.54 cm² over the axillary. METHODS: Forty patients with unilateral lymphedema were enrolled in this double-blind, placebo-controlled trial in order to evaluate effects of PBMT on lymphedema-related pain, quality of life, grip strength and limb volume difference. Subjects received irradiation for ten minutes per session using a cluster laser covering a beam area of 78.54 cm². The applied energy was 384 Joules resulting in an energy density of 4.89 J/cm². RESULTS: Post-treatment, a 50% reduction in median pain scores and an increase in mean quality of life were observed. Mean grip strength was persistently higher after eight sessions of PBMT compared with pretreatment; however, no statistically significant intergroup differences (P > 0.05) were found over the time course. CONCLUSION: PBMT using a compactly designed treatment regime in combination with a cluster laser device did not significantly improve quality of life, pain scores, grip strength and limb volume over the time course.

Differences in use of complementary and alternative medicine between children and adolescents with cancer in Germany: a population based survey.

BACKGROUND: Use of complementary and alternative medicine (CAM) in children with cancer is common and probably increasing. However, data concerning differences between children and adolescents focusing on prevalence, reasons for use/non-use, costs, adverse effects, and socio-demographic factors are lacking. PROCEDURE: A population-based survey over a 1 year period with 497 participants was conducted. RESULTS: Of the 457 respondents (92%) 322 were children and 135 adolescents (>16 years of age) with malignancies. 31% reported CAM use from the time when being diagnosed, compared to an overall lifetime prevalence rate of 41% before cancer diagnosis. Among CAM users the most prevalent therapies were homeopathy, massage, anthroposophic medicine, acupuncture, and Bach flowers. The main reasons for use were to reduce therapy-related side effects, to strengthen the immune system, to achieve physical stabilization and to increase healing chances. Socio-demographic factors associated with CAM use were higher parental education and higher family income. A majority of CAM users (97%) would recommend CAM use. Most users (78%) informed a physician about CAM use. Side effects were rarely reported (5%), minor and self-limiting. CONCLUSIONS: The high prevalence rates seem to represent the parental or patients needs for additional treatment perceived as successful and devoid of side-effects. Clinical care and the physician-patient relation would profit from an enhanced understanding of CAM and a greater candidness towards the parental needs. Safety and efficacy - especially of CAM with high prevalence rates - should be studied in rigorous basic and clinical research.

Pain in tones - Is it possible to hear the pain quality? A pilot trial.

OBJECTIVE: The adequate treatment of chronic pain also calls for measuring its quality not only its intensity. For this reason, this pilot study investigated the non-verbal description of pain quality based on tones, distinguishing between nociceptive and neuropathic pain. METHODS: A nociceptive and a neuropathic pain stimulus were applied to 80 chronic pain patients and 80 healthy subjects. Using a tone generator, all participants matched both pain stimuli to an appropriate tone (in Hz). The stimulus intensity was measured using the NRS-scale, and the PainDETECT questionnaire was completed. RESULTS: Both groups matched a significantly higher tone to the neuropathic than to the nociceptive pain stimulus. Compared to healthy participants, chronic pain patients allocated higher tones to both pain stimuli. Higher values were also shown for the neuropathic pain stimulus, and chronic pain patients indicated an overall higher intensity of pain as healthy participants. CONCLUSIONS: It is possible to differentiate pain stimuli non-verbally through tones, however, whether quality or intensity, was the key factor remains unknown. Future studies could investigate the influence of additional factors. PRACTICAL IMPLICATIONS: A practical tool using tones should be developed to detect pain quality in patients - without verbal descriptions - quickly and more precisely.

Use of complementary and alternative medicine in healthy children and children with chronic medical conditions in Germany.

OBJECTIVES: Use of complementary and alternative medicine (CAM) in children is common and probably increasing. However little is known about differences between healthy and chronically ill children with a focus on prevalence, reasons for use/non-use, costs, adverse effects and socio-demographic factors. DESIGN: A questionnaire-based survey with 500 participants visiting the outpatient clinic of the University Children's Hospital Homburg, Germany was conducted over a 4-week period in 2004. Recruitment was stopped when 500 questionnaires were handed out in total. RESULTS: Of the 405 (81%) respondents (242 with chronic conditions, 163 healthy children incidentally visiting the hospital for minor ailments) 229 (57%) reported lifetime CAM use (59% with chronic conditions versus 53% healthy children). Among CAM users the most prevalent therapies were homeopathy (25%), herbal remedies (8%), anthroposophic medicine (7%), vitamin preparations (6%) and acupuncture (5%). The main reasons for use were to strengthen the immune system, physical stabilisation and to increase healing chances/maintain health. Socio-demographic factors associated with CAM use were tertiary education (mother: p=0.017; father: p>0.001), higher family income (p=0.001) and being Protestant (p=0.01). Expectations towards CAM were high and most parents would recommend certain CAM (94%). 79% of the users informed a physician about CAM use. Side effects were rarely reported (4%), minor and self-limiting. CONCLUSIONS: Clinical care and the physician-patient relation would benefit from an enhanced understanding of CAM and a greater candidness towards the parental needs. The safety and efficacy especially of CAM with high prevalence rates should be determined in rigorous basic and clinical researches.
