Lordoplasty: midterm outcome of an alternative augmentation technique for vertebral fractures.

OBJECTIVE Vertebroplasty and balloon kyphoplasty are effective treatment options for osteoporotic vertebral compression fractures but are limited in correction of kyphotic deformity. Lordoplasty has been reported as an alternative, cost-effective, minimally invasive, percutaneous cement augmentation technique with good restoration of vertebral body height and alignment. The authors report on its clinical and radiological midterm results. METHODS A retrospective review was conducted of patients treated with lordoplasty from 2002 to 2014. Inclusion criteria were clinical and radiological follow-up evaluations longer than 24 months. Radiographs were accessed regarding initial correction and progressive loss of reduction. Complications and reoperations were recorded. Actual pain level, pain relief immediately after surgery, autonomy, and subjective impression of improvement of posture were assessed by questionnaire. RESULTS Sixty-five patients (46 women, 19 men, age range 38.9-86.2 years old) were treated with lordoplasty for 69 vertebral compression and insufficiency fractures. A significant correction of the vertebral kyphotic angle (mean 13°) and segmental kyphotic angle (mean 11°) over a mean follow-up of 33 months (range 24-108 months) was achieved (p < 0.001). On average, pain was relieved to 90% of the initial pain level. In 24% of the 65 patients a second spinal intervention was necessary: 16 distant (24.6%) and 7 adjacent (10.8%) new osteoporotic fractures, 4 instrumented stabilizations (6.2%), 1 new adjacent traumatic fracture (1.5%), and 1 distant microsurgical decompression (1.5%). Cement leakage occurred in 10.4% but was only symptomatic in 1 case. CONCLUSIONS Lordoplasty appeared safe and effective in midterm pain alleviation and restoration of kyphotic deformity in osteoporotic compression and insufficiency fractures. The outcomes of lordoplasty are consistent with other augmentation techniques.

The enduring effects of psychodynamic treatments vis-à-vis alternative treatments: A multilevel longitudinal meta-analysis

Although evidence suggests that the benefits of psychodynamic treatments are sustained over time, presently it is unclear whether these sustained benefits are superior to non-psychodynamic treatments. Additionally, the extant literature comparing the sustained benefits of psychodynamic treatments compared to alternative treatments is limited with methodological shortcomings. The purpose of the current study was to conduct a rigorous test of the growth of the benefits of psychodynamic treatments relative to alternative treatments across distinct domains of change (i.e., all outcome measures, targeted outcome measures, non-targeted outcome measures, and personality outcome measures). To do so, the study employed strict inclusion criteria to identify randomized clinical trials that directly compared at least one bona fide psychodynamic treatment and one bona fide non-psychodynamic treatment. Hierarchical linear modeling (Raudenbush, Bryk, Cheong, Congdon, & du Toit, 2011) was used to longitudinally model the impact of psychodynamic treatments compared to non-psychodynamic treatments at post-treatment and to compare the growth (i.e., slope) of effects beyond treatment completion. Findings from the present meta-analysis indicated that psychodynamic treatments and non-psychodynamic treatments were equally efficacious at post-treatment and at follow-up for combined outcomes (k=20), targeted outcomes (k=19), non-targeted outcomes (k=17), and personality outcomes (k=6). Clinical implications, directions for future research, and limitations are discussed.

A systematic review of the evidence for use of herbal medicine for the treatment of acute diarrhea

Background. Acute diarrhea (AD) is an important cause of morbidity and mortality among both children and adults. An ideal antidiarrheal treatment should be safe, effective, compatible with Oral Rehydration Solution, and inexpensive. Herbal medicines, if effective, should fit these criteria as well or better than standard treatment. ^ Objective. The objective of the present study was to assess the effectiveness of plant preparations in patients with AD in reports of randomized and non-randomized controlled trials. ^ Aims. The aims of the present study were to identify effective antidiarrheal herbs and to identify potential antidiarrheal herbs for future studies of efficacy through well designed clinical trials in human populations. ^ Methods. Nineteen published studies of herbal management of AD were examined to identify effective plant preparations. Ten plant preparations including Berberine (Berberis aristata), tormentil root ( Potentialla tormentilla), baohauhau (from the baobaosan plant), carob (Ceratonia siliqua), pectin (Malus domestica), wood creosote (Creosote bush), guava (Psidium guajava L.), belladonna (Atropa belladonna), white bean (Phaseolis vulgaris), and wheat (Triticum aestivum) were identified. ^ Results. Qualitative data analysis of nineteen clinical trials indicated berberine’s potentially valuable antisecretory effects against diarrhea caused by Vibrio cholerae and enterotoxigenic Escherichia coli. Tormentil root showed significant efficacy against rotavirus-induced diarrhea; carob exhibited antidiarrheal properties not only by acting to detoxify and constipate but by providing a rich source of calories; guava and belladonna are antispasmodics and have been shown to relieve the symptoms of AD. Finally, white bean and wheat yielded favorable clinical and dietary outcomes in children with diarrhea. ^ Conclusion. The present study is the first to review the evidence for use of herbal compounds for treatment of AD. Future randomized controlled trials are needed to evaluate their efficacy and safety.^

Evaluating alternative therapies. Support/imagery and immune function in breast cancer: A pilot study

Cancer patients increasingly request alternative therapies such as imagery techniques and support groups. Although research suggests evidence of enhanced psychosocial functioning with supportive group therapy and enhanced immune function with imagery techniques, studies are anecdotal or limited to case studies or descriptive reports. The efficacy of these alternative therapies should be validated by randomized, controlled trials and the mechanisms of action mediating immune function and outcome examined.^ In a 12-month pilot study, we evaluate the feasibility of conducting a controlled study with clinical trial methodology to test the effects of imagery/relaxation and support on quality of life, emotional well-being, and immune function for women after breast cancer. Using a randomized pre-post test design with three intervention waves, we assigned women (n = 47) to either standard care (n = 15), standard care plus 6-weekly support sessions (n = 16) or imagery/relaxation sessions (n = 16).^ The primary aim of this pilot study is to determine the feasibility of conducting a clinical trial of alternative therapies in a clinical care setting. Secondary aims are to determine parameter estimates for the effects of the two treatment groups on quality of life, coping, social support, and immune function and describe methodology issues related to trials of alternative therapies.^ The research provides direction for future studies of alternative therapies by describing the recruitment, clinical trial experience, and related methodology issues. The study extends previous work by differentiating the effects of support group from mental imagery among outpatient groups who are homogeneous regarding cancer type and treatment stage. The study provides data for future longitudinal studies of disease progression by differentiating the effectiveness of interventions designed to enhance quality of life, coping, social support, and immune function and subsequently, alter the clinical course of disease. ^

A Pre-Clinical Assessment of Minocycline for Treatment of Chronic Neuropathic Pain after Spinal Cord Injury

Patients living with a spinal cord injury (SCI) often develop chronic neuropathic pain (CNP). Unfortunately, the clinically approved, current standard of treatment, gabapentin, only provides temporary pain relief. This treatment can cause numerous adverse side effects that negatively affect the daily lives of SCI patients. There is a great need for alternative, effective treatments for SCI-dependent CNP. Minocycline, an FDA-approved antibiotic, has been widely prescribed for the treatment of acne for several decades. However, recent studies demonstrate that minocycline has neuroprotective properties in several pre-clinical rodent models of CNS trauma and disease. Pre-clinical studies also show that short-term minocycline treatment can prevent the onset of CNP when delivered during the acute stage of SCI and can also transiently attenuate established CNP when delivered briefly during the chronic stage of SCI. However, the potential to abolish or attenuate CNP via long-term administration of minocycline after SCI is unknown. The purpose of this study was to investigate the potential efficacy and safety of long-term administration of minocycline to abolish or attenuate CNP following SCI. A severe spinal contusion injury was administered on adult, male, Sprague-Dawley rats. At day 29 post-injury, I initiated a three-week treatment regimen of daily administration with minocycline (50 mg/kg), gabapentin (50 mg/kg) or saline. The minocycline treatment group demonstrated a significant reduction in below-level mechanical allodynia and above- level hyperalgesia while on their treatment regimen. After a ten-day washout period of minocycline, the animals continued to demonstrate a significant reduction in below-level mechanical allodynia and above-level hyperalgesia. However, minocycline-treated animals exhibited abnormal weight gain and hepatotoxicity compared to gapabentin-treated or vehicle-treated subjects.The results support previous findings that minocycline can attenuate CNP after SCI and suggested that minocycline can also attenuate CNP via long-term delivery of minocycline after SCI (36). The data also suggested that minocycline had a lasting effect at reducing pain symptoms. However, the adverse side effects of long-term use of minocycline should not be ignored in the rodent model. Gabapentin treatment caused a significant decrease in below-level mechanical allodynia and below-level hyperalgesia during the treatment regimen. Because gabapentin treatment has an analgesic effect at the concentration I administered, the results were expected. However, I also found that gabapentin-treated animals demonstrated a sustained reduction in pain ten days after treatment withdrawal. This result was unexpected because gabapentin has a short half-life of 1.7 hours in rodents and previous studies have demonstrated that pre-drug pain levels return shortly after withdrawal of treatment. Additionally, the gabapentin-treated animals demonstrated a significant and sustained increase in rearing events compared with all other treatment groups which suggested that gabapentin treatment was not only capable of reducing pain long-term but may also significantly improve trunk stability or improve motor function recovery.

Bench-scale evaluation of the activated sludge process for treatment of a high -strength chemical plant wastewater

A bench-scale treatability study was conducted on a high-strength wastewater from a chemical plant to develop an alternative for the existing waste stabilization pond treatment system. The objective of this study was to determine the treatability of the wastewater by the activated sludge process and, if treatable, to determine appropriate operating conditions, and to evaluate the degradability of bis(2-chloroethyl)ether (Chlorex) and benzene in the activated sludge system. Four 4-L Plexi-glass, complete mixing, continuous flow activated sludge reactors were operated in parallel under different operating conditions over a 6-month period. The operating conditions examined were hydraulic retention time (HRT), sludge retention time (SRT), nutrient supplement, and Chlorex/benzene spikes. Generally the activated sludge system treating high-strength wastewater was stable under large variations of organic loading and operating conditions. At an HRT of 2 days, more than 90% removal efficiency with good sludge settleability was achieved when the organic loading was less than 0.4 g BOD$\sb5$/g MLVSS/d or 0.8 g COD/g MLVSS/d. At least 20 days of SRT was required to maintain steady operation. Phosphorus addition enhanced the performance of the system especially during stressed operation. On the average, removals of benzene and Chlorex were 73-86% and 37-65%, respectively. In addition, the low-strength wastewater was treatable by activated sludge process, showing more than 90% BOD removal at a HRT of 0.5 days. In general, the sludge had poor settling characteristics. The aerated lagoon process treating high-strength wastewater also provided significant organic reduction, but did not produce an acceptable effluent concentration. ^

Rethinking special and differential treatment in the WTO

Special and differential treatment (S&D) allows differentiated treatment for developing countries within the WTO system by justifying a deviation from the most-favoured-nation obligation. Since it was incorporated into the GATT (the predecessor of the WTO) in the 1960s, S&D has played a significant role in promoting the integration of developing countries into the multilateral trading system. However, S&D is undergoing complicated and entangled discussion at the current multilateral trade negotiations, the Doha Development Agenda. There are a number of reasons to make opposing arguments in developed and developing countries, among which this paper focuses on two elements: diversification of developing countries and instability of preferential schemes. In order to overcome these problems and in order to make S&D more effective and operational, this paper considers the following alternative approaches: differentiation among developing countries applying the common but differentiated responsibility (CBDR) principle by analogy and codification of a preferential scheme as a multilateral agreement in the manner of North-South RTAs with flexibility.

Guidelines of natural zeolites characterization for acid mine drainage treatment. Case study Guayaquil, Ecuador

Zeolites constitute one of the less common groups of tectosilicates. Zeoli1es with pores between -2 to 10 A in their structures have strong sorption capacity and are widely used in industrial and municipal operations to eliminate toxic substances. One of the major environmental problems in the mining activity is the treating of acid mine drainage. In this context, it is very important to search alternatives to manage this challenge. One feasible alternative is using zeolitic tuffs. The results of the physical-chemical characterization of zeolitic tuffs are the c1ue lo continue or not with deeper analysis and tests 01 acid mine drainage treatments. The guidelines to reach this purpose are the main goal of this work. Zeolite 1uff samples (named as XB_01 and XB_02) studied in this work were laken rn the Late Cretaceous Coastal Cayo Arch Ecuador, specifically in the Guaraguao River, showing the most important characteristics of heulandite zeolitic tuffs. X-ray powder diffraction (XRD) tests were developed in order to confirm that the samples belong to the heulandite-type zeoli1ic tuffs. Additionally, Thermogravimetric analysis (TG), Inductively coupled plasma-atomic emission spectroscopy (ICP-AES) and X-ray fluorescence (XRF) of the samples was necessary in order to define the Si/Al ratio and the main mineralogical phases. The XB_01 sample shows a higher ratio Si/Al than XB_02 sample. The cation exchange capacity est was the fundamental step to define the potentiality of the zeolite to use in acid mine drainage treatment Three methodologies were employed to determine the cation exchange capacity. The Cuban standard 626 and the ammonium exchange methodologies reflect results more consistent with each other. This is the starting point to continue with deeper studies such as breakthrough curves for heavy metal ions found in acid mine waters.

Saline Stress Alters the Temporal Patterns of Xylem Differentiation and Alternative Oxidase Expression in Developing Soybean Roots1

We conducted a coordinated biochemical and morphometric analysis of the effect of saline conditions on the differentiation zone of developing soybean (Glycine max L.) roots. Between d 3 and d 14 for seedlings grown in control or NaCl-supplemented medium, we studied (a) the temporal evolution of the respiratory alternative oxidase (AOX) capacity in correlation with the expression and localization of AOX protein analyzed by tissue-print immunoblotting; (b) the temporal evolution and tissue localization of a peroxidase activity involved in lignification; and (c) the structural changes, visualized by light microscopy and quantified by image digitization. The results revealed that saline stress retards primary xylem differentiation. There is a corresponding delay in the temporal pattern of AOX expression, which is consistent with the xylem-specific localization of AOX protein and the idea that this enzyme is linked to xylem development. An NaCl-induced acceleration of the development of secondary xylem was also observed. However, the temporal pattern of a peroxidase activity localized in the primary and secondary xylem was unaltered by NaCl treatment. Thus, the NaCl-stressed root was specifically affected in the temporal patterns of AOX expression and xylem development.

B-cell activation by crosslinking of surface IgM or ligation of CD40 involves alternative signal pathways and results in different B-cell phenotypes.

Treatment of small resting B cells with soluble F(ab')2 fragments of anti-IgM, an analogue of T-independent type 2 antigens, induced activation characterized by proliferation and the expression of surface CD5. In contrast, B cells induced to proliferate in response to thymus-dependent inductive signals provided by either fixed activated T-helper 2 cells or soluble CD40 ligand-CD8 (CD40L) recombinant protein displayed elevated levels of CD23 (Fc epsilon II receptor) and no surface CD5. Treatment with anti-IgM and CD40L induced higher levels of proliferation and generated a single population of B cells coexpressing minimal amounts of CD5 and only a slight elevation of CD23. Anti-IgM- but not CD40L-mediated activation was highly sensitive to inhibition by cyclosporin A and FK520. Sp-cAMPS, an analogue of cAMP, augmented CD40L and suppressed surface IgM-mediated activation. Taken together these results are interpreted to mean that there is a single population of small resting B cells that can respond to either T-independent type 2 (surface IgM)- or T-dependent (CD40)-mediated activation. In response to different intracellular signals these cells are induced to enter alternative differentiation pathways.

An un-mounted horse care group for children and youth with an Autism Spectrum Disorder: Recommendations for program development and treatment intervention

Equine Assisted Activities and Therapies (EAAT) including Therapeutic Horseback Riding (THR) and un-mounted equine assisted activities are interventions aimed at improving the daily functioning and success of individuals with disabilities, including those with an autism spectrum disorder (ASD). While THR is frequently utilized as a treatment intervention for children with ASD, there are many limitations (individual's weight, horse health, weather, physical limitations, health conditions, etc.) that prevent this population from participating in mounted programs. Un-mounted equine assisted activities are often utilized as an alternative, but they are not informed by empirical research or a standardized treatment model. This paper provides a comprehensive review of the literature for EAAT including un-mounted programs, examination of organizational guidelines as they apply to un-mounted programs, and consultation with program directors regarding current practices in the field, and finally it establishes recommendations for the development of a standard curriculum that would strengthen un-mounted horse care group programs serving children with ASD.

Cross-Disciplinary Collaboration Behavior of Practitioners in the Treatment of Anxiety Disorders

Current research on the collaborative behaviors of conventional and alternative health care providers for the treatment of anxiety is lacking. While there are multiple studies looking at alternative health care integration into primary care, none of them look at anxiety specifically. The purpose of this paper is to provide a preliminary exploration of possible barriers to collaboration between conventional and alternative health care providers for the treatment of anxiety. Quantitative data on collaboration behavior patterns were obtained with an anonymous survey. Data from the surveys were analyzed using a chi-square analysis. Along with these numerical data narrative data from the survey and interviews were collected in order to assess beliefs about the barriers to collaboration from different health care providers. The results indicate that conventional providers collaborate the least with alternative providers and alternative providers collaborate the least with conventional providers. The descriptive results regarding the barriers to collaboration from the study illustrated a common theme, specifically, the lack of education of conventional providers on alternative health care practices on anxiety. This is an exploratory study: therefore it would be beneficial for future researchers to look deeper into the beliefs of health care providers on the barriers to collaboration, possibly identifying the specific barriers to collaboration for each type of healthcare provider.

Botulinum Toxin as an Alternative to Treat the Spasm of the Near Reflex

We describe the case of an eight-year-old girl with complaints of headaches and blurred vision (uncorrected visual acuity: 0.1 decimal) that showed on examination miotic pupils, pseudomyopia, no ocular motility restrictions, and no associated neurological disease. After initial treatment with cyclopentolate for two months, pseudomyopia persisted with an intermittent and variable esotropia. Spectacles of +1 both eyes and atropine 1% one drop daily were then prescribed. The situation improved and remained stable for several weeks, with pseudomyopia and esotropia reappearing later. Finally, botulinum toxin (2.5 iu Botox®) was injected in the medial rectus muscle on two occasions and a visual therapy program based on the stimulation of fusional divergence, diplopia, and stereopsis consciousness was recommended. This prescription was combined with the use of atropine during the first few weeks. Orthotropia and corrected distance visual acuity of 1.0 were found three months after treatment. The evolution and clinical results of this case report suggest that botulinum toxin in combination with other therapeutic alternatives may be useful in the treatment of spasm of the near reflex.
