Study Design. A cross-sectional survey of 2083 schoolchildren. Objective. To investigate the prevalence of nonspecific low back pain (LBP) among schoolchildren aged between 10 and 18 years in China. Summary of Background Data. LBP have been a serious health problem in schoolchildren. On the basis of literature, the lifetime occurrence of nonspecific LBP in children and adolescents varies between 7% and 72%, but little is known about LBP among this demographic group in China. Methods. Schoolchildren aged 10 to 18 years were sampled from two grades in an elementary school and four grades in a secondary school. Participants were asked to fill in a questionnaire on LBP. The questionnaire addressed demographic items, anthropometric factors and characteristics of nonspecific LBP, such as frequency, duration, nature, pain scale. Nonspecific LBP is defined as the pain in the back from the 12th ribs to the buttock area without organic factors. A total of 2235 questionnaires were distributed, of which 2100 were answered, a response rate of 93.7%. Among those answers, 2083 (977 from male students and 1106 from female students) provided measurable data. Results. The occurrence of nonspecific LBP was high, with 29.1% students suffering from this condition in the past 3 months (24.7% in boys, 33.1% in girls). In addition, an increased occurrence was observed with age. The occurrences of LBP in 10 to 14 years and 15 to 18 years were 21.5% and 38.2%, respectively. In several aspects of LBP, statistically significant differences were observed between boys and girls, including the frequency of the pain (P = 0.003), the nature of the pain (P = 0.000), the likelihood of seeking for medical assistance (P = 0.007), the impact on normal daily life (P = 0.016), and the occurrence of LBP after bending over the desk for a period of time (P = 0.024). Female students had more frequent LBP and were less willing to see a physician. In addition, more female students (45/366) had LBP accompanied with radiating pain than male students (20/241). Conclusion. There is a high prevalence of LBP in Chinese schoolchildren. The occurrence of LBP increases with age in both sexes. LBP is significantly more prevalent in girls. © 2011, Lippincott Williams & Wilkins.

We report a case of metastatic papillary thyroid carcinoma and undifferentiated nonkeratinizing nasopharyngeal carcinoma to the same cervical lymph node following chemotherapy for mantle cell lymphoma. Total thyroidectomy, right cervical nodal dissection, radioactive iodine-131 therapy and radiotherapy to the nasopharynx and the neck resulted in remission of both tumors. No recurrence was noted in follow-up for 48 months.

PURPOSE: The objective of this study was to perform a systematic review and meta-analysis of the effects of statins on mortality for patients with non-severe pneumonia or severe pneumonia. METHODS: PubMed, EMBASE, Cochrane Database of Systematic Reviews, Cochrane central register of controlled trials and were searched for the association between statins and non-severe/severe pneumonia. Eligible articles were analyzed in Stata 12.0. RESULTS: The database search yielded a total of 566 potential publications, 24 studies involving 312,309 patients met the eligibility criteria. Pooled unadjusted data showed that statin use was associated with lower mortality after non-severe pneumonia (odds ratio [OR] 0.70, 95% confidence interval [CI], 0.66-0.73), but not severe pneumonia (OR 1.05; 95% CI, 0.86-1.28). However, this protective effect of statins was weakened using adjusted estimates (OR 0.78, 95% CI, 0.75-0.82). Besides, protective effect of statins was attenuated by confounders in a subgroup analysis, especially when accounting for pneumonia severity indicators (OR 0.88; 95% CI, 0.80-0.96). CONCLUSIONS: Statin use was associated with reduced mortality after non-severe pneumonia but not severe pneumonia and this protective effect was weakened in subgroups. © 2015 Canadian Society for Pharmaceutical Sciences.

Photodiagnosis and Photodynamic Therapy | Year: 2012

Background: Several Chinese studies suggest that Hemoporfin-mediated photodynamic therapy (PDT) is an alternative treatment for port-wine stain (PWS) birthmarks. Objective: To evaluate treatment responses and adverse effects associated with Hemoporfin PDT for the treatment of PWS and their management. Method: The medical records of 700 patients who underwent PDT treatment in our center were retrospectively examined. Treatment-related reactions and adverse effects were reviewed. Result: Different types of PWS lesions and different individuals showed different immediate responses (e.g. swelling, color change, pain). To certain extents these reactions were a useful indicator of the treatment endpoint. Edema and scabbing were the most common post-treatment responses. Short-term (e.g. blister, eczematous dermatitis, cutaneous photosensitivity) and long-term (e.g. pigmentation change, scar formation) adverse effects were generally caused by the phototoxicity associated with the combination of photosensitizer and light exposure. Conclusion: Although PDT is a safe treatment alternative for PWS birthmarks, treatment parameters must be selected for each individual patient and cutaneous changes must be monitored during light irradiation to minimize the risk of adverse effects. Over estimation of required light dosage or failure to recognize cutaneous changes associated with adverse effects can increase the risk of a poor outcome. © 2012 Elsevier B.V.

AimsA prothrombotic state with elevated levels of soluble P-selectin (sP-sel), fibrinogen, von Willebrand factor (vWf), and other haemostatic indices has been reported in some patients with atrial fibrillation (AF). Whether these changes are due to AF itself or coexistent cardiovascular diseases remains a matter of debate. Therefore, in the present study, the differences in plasma levels of sP-sel, fibrinogen, and vWf between patients with idiopathic/lone AF and sex-, age-, and risk factor-matched controls were investigated to determine whether AF itself might be associated with a hypercoagulable state.Methods and resultsNinety consecutive patients (63 males, 54.1 ± 10.1 years) with idiopathic AF were studied, 60 (43 males, 48.8 ± 7.5 years) of whom were diagnosed as lone AF. Plasma sP-sel and vWf were measured by enzyme-linked immunosorbent assay. Plasma fibrinogen was measured by chromometry. These indices in AF patients were compared with those in sex-, age- and risk factor-matched controls.Compared with the controls, patients with idiopathic AF had higher levels of sP-sel (AF vs. control: 33.4 ± 7.4 vs. 29.2 ± 6.5 ng/mL, P < 0.001) and fibrinogen (AF vs. control: 3.3 ± 0.9 vs. 3.0 ± 0.6 g/L, P 0.02), but not vWf, whether with the adjustment of covariates or not. As for those <60 years, between lone AF and age-matched controls, significant difference existed in the levels of sP-sel (AF vs. control: 34.5 ± 7.3 vs. 30.2 ± 7.3 ng/mL, P 0.002), but not in those of fibrinogen and vWf, whether with the adjustment of covariates or not.ConclusionsBoth platelet activation and abnormal changes in coagulation were suggested in idiopathic AF and a platelet activation state in lone AF. This supports the notion that AF per se contributes to a state of hypercoagulation. Published on behalf of the European Society of Cardiology. All rights reserved. © The Author 2010.

Objectives: This study aimed to compare the clinical efficacies of percutaneous endoscopic lumbar discectomy (PELD) and traditional open lumbar discectomy (OD). Methods: The pre-operative and post-operative blood loss, hospital stays and wound sizes of the patients in the two groups were recorded. Enzyme-Linked immunosorbent assay was used to measure the changes of interleukin-6 (IL-6), C-reactive protein (CRP) and creatine phosphokinase (CPK) pre-operation and 1h, 6h, 12h, 24h and 48h after corresponding surgery. Visual Analog Scale and Modified MacNab Criteria were used to assess post-operative results. Results: Patients in the PELD group had less blood loss (p<0.01), shorter hospitalization hours (p<0.01) and smaller surgical wounds (p<0.01) than the patients underwent traditional OD surgery. MacNab evaluated that the levels of satisfaction were above 90% in both groups post-operative six months. There was no significant difference in pain index between the two groups (p>0.05). Furthermore, the levels of CRP, CPK and IL-6 in the PELD group were all lower than those in the OD group with a significant difference (p<0.01). Conclusion: The PELD had less damage to human tissues than the traditional OD. PELD has a clear promotional value in clinical. © 2014 Surgical Associates Ltd.

Objectives. The objective of this study was to gain a basic understanding of the influential factors for nonspecific low-back pain (LBP) among adolescents of southern China. Design. The study was designed as a school-based case control study. Setting. Nonspecific LBP is a common health problem in adolescence. Although some behaviors and socio-demographic factors are believed to contribute to the disorder, influential factors of LBP remain undefined. Moreover, until now there is no available information of influential factors for LBP in Chinese adolescents. Subjects. A total of 1,214 adolescents were involved in the study, including 607 cases with nonspecific LBP and 607 controls without history of nonspecific LBP. Outcome Measures. A self-administered questionnaire was designed for epidemiological survey to investigate the risk factors for nonspecific LBP. All cases and controls were investigated for their family histories of nonspecific LBP, physical activities, sedentary activities, schoolbag weights, school performances, living conditions, and etc. Method. A 1:1 matched case-control study was conducted on 1,214 adolescents from an elementary school and a secondary school in Guangzhou City, southern China. Results. Family history (odds ratio [OR] 2.57, 95% confidence interval [CI] 1.85-3.58), long duration of carrying schoolbag (OR 1.38, 95% CI 1.11-1.72) and rest position between classes (OR 1.18, 95% CI 1.01-1.39) were positively correlated with self-reported nonspecific LBP. Students regularly playing basketball (OR 1.58, 95% CI 1.09-2.30) was found to be significantly more likely to have LBP. Also, students who feel schoolbag uncomfortable (OR 1.38, 95% CI 1.11-1.72) was found to experience more LBP. Conclusions. Family history, feeling schoolbag uncomfortable, duration of schoolbag carrying, basketball playing and rest position between classes are the major risk factors for nonspecific LBP in adolescents.

Irreversible vision loss is most often caused by the loss of function and subsequent death of retinal neurons, such as photoreceptor cells - the cells that initiate vision by capturing and transducing signals of light. One reason why retinal degenerative diseases are devastating is that, once retinal neurons are lost, they don't grow back. Stem cell-based cell replacement strategy for retinal degenerative diseases are leading the way in clinical trials of transplantation therapy, and the exciting findings in both human and animal models point to the possibility of restoring vision through a cell replacement regenerative approach. A less invasive method of retinal regeneration by mobilizing endogenous stem cells is, thus, highly desirable and promising for restoring vision. Although many obstacles remain to be overcome, the field of endogenous retinal repair is progressing at a rapid pace, with encouraging results in recent years. © 2014 Mosby, Inc.

Background Pulsed-dye laser (PDL)-mediated photothermolysis is the current standard treatment for port-wine stain (PWS) birthmarks. Vascular-targeted photodynamic therapy (PDT) might be an alternative for the treatment of PWS. Objectives To compare clinical outcomes of PDT and PDL treatment of PWS. Methods Two adjacent flat areas of PWS lesions were selected from each of 15 patients (two male and 13 female; age 11-36 years) and randomly assigned to either single-session PDL or PDT. PDL was delivered using a 585-nm pulsed laser. PDT was carried out with a combination of haematoporphyrin monomethyl ether (HMME) and a low-power copper vapour laser (510·6 and 578·2 nm). Clinical outcomes were evaluated colorimetrically and visually during follow-up. Results A total of nine red PWS lesions and six purple PWS lesions were treated. For red PWS, colorimetric assessment showed that the blanching rates of PDL and PDT at 2 months ranged from -11% to 24% and 22% to 55%, respectively. For purple PWS, blanching rates of PDL and PDT ranged from 8% to 33% and 30% to 45%, respectively. Overall, there was a significant difference between the blanching effect of single-session PDL treatment and a single-session PDT treatment. Conclusions This side-by-side comparison demonstrates that PDT is at least as effective as PDL and, in some cases, superior. The true value of PDT for the treatment of PWS deserves further investigation. What's already known about this topic? To date, several Chinese studies of photodynamic therapy (PDT) for port-wine stains (PWS) indicate that this therapeutic modality is effective and safe for the treatment of PWS of all colour and in all ages. Our retrospective study suggested that PDT is as effective as pulsed-dye laser (PDL) treatment for pink PWS and more effective than PDL for purple PWS. What does this study add? This is the first side-by-side and quantitative comparison of PDL and PDT. The findings reported here confirm that PDT is at least as effective and safe as PDL, if not superior to, for the treatment of red and purple flat PWS. © 2012 The Authors.

Study Design.: Retrospective report of two surgical cases and review of the literature. Objective.: To report the clinical application of transoral atlantoaxial reduction plate (TARP) internal fixation with a novel technique of transoral transpedicular or articular mass screw of C2 in the treatment of irreducible atlantoaxial dislocation and basilar invagination with ventral spinal cord compression. Summary of Background Data.: Current surgical treatments for IAAD have various disadvantages, such as posterior decompression followed by atlantoaxial or occipitocervical fusion with unsatisfactory decompression, transoral decompression, and one-stage posterior instrumentation needing two approaches although with satisfactory decompression, resection of dens and/or clivus with potential risk of spinal cord injury and CSF leakeage. Methods.: TARP system with a novel technique of transoral transpedicular screw or articular mass screw of C2 was designed and employed for two patients with irreducible atlantoaxial dislocation, during which one case was with basilar invagination. The histories of the cases and the novel technique of transoral articular mass screw and transpedicular screw insertion of C2 were reported in detail. Results.: The two case examples demonstrate the efficacy of this one-stage single transoral approach to the surgical treatment of irreducible anterior atlantoaxial dislocation with spinal cord compression especially in the case of basilar invagination. The role of the TARP in affecting and maintaining the reduction while promoting successful fusion is illustrated. Conclusion.: The authors' one-stage anterior procedure employing the TARP for the surgical treatment of irreducible anterior atlantoaxial dislocation and basilar invagination was effective in these two cases. This method was able to avoid the need for dens and clivus resection and/or a posterior instrumentation and fusion procedure. The technique of transoral articular mass screw and transpedicular screw insertion of C2 was valuable for transoral atlantoaxial plate internal fixation. © 2011 Lippincott Williams & Wilkins.
