    In this article we review the current literature addressing the treatment of schizophrenia with vitamin supplementation. We first describe the important roles that vitamins play in normal metabolism, then review the evidence pertaining to vitamin deficiency and supplementation in patients with schizophrenia. We then describe mounting evidence suggesting that vitamin supplementation, in particular with folic acid, vitamin B12 and vitamin D, may be important in treatment within certain subgroups of patients. We highlight the need for larger, randomized controlled trials, and recommend further studies examining the incidence of schizophrenia in countries with poor prenatal care and malnutrition, as well as in countries that have adopted mandatory folic acid fortification of grain products.

    Full Text Available Background: Mammalian pigmentation results from the synthesis and accumulation of photo protective epidermal melanin. Melanin was formed from the amino acid precursor L-tyrosine within specialized cells, the melanocytes. Oxidative stress has been suggested to be the initial pathogenetic event in melanocyte degeneration with H 2 O 2 accumulation in the epidermis of patients with active disease. Auto immunity has been also suggested as another hypothesis in the pathogenesis of depigmentation disorders. Topical corticosteroids and phototherapy as common treatment modalities have been prescribed in patients with vitiligo. However, they are often not effective and safe (epidermal atrophy. Therefore, research for alternative therapies continues. Aims: To evaluate the beneficial effects of a supplementation with antioxidant vitamins (A, C, E and minerals (zinc, selenium for vitiligo treatment. Methods: Forty experimental autoimmune vitiligo mice C57BL6, aged from 5 to 12 months showing visible signs of induced vitiligo, were sequentially randomized into five parallel groups (8 mice per group.

    2005-08-01

    The technique of intrafocal pinning was originally described by Kapandji. This technique, along with the addition of supplemental external or internal bridging fixation, can be performed quickly with minimal soft tissue damage. This technique is indicated for the treatment of unstable extra-articular or minimally displaced intra-articular fractures of the distal radius. Studies demonstrate that young patients with displaced extra-articular distal radius fractures and minimal comminution can be treated by percutaneous intrafocal pin fixation alone, whereas, patients over 55 years of age and younger patients with comminution involving two or more surfaces of the radial metaphysis (or > 50% of the metaphyseal diameter) require bridging fixation besides percutaneous pin fixation. The use of this technique achieves the goal of surgical treatment of distal radius fractures: restoration of hand and wrist function through the restoration of alignment and articular surface congruity.

    absence of fever between children who received zinc supplements and those who did not (HR 1.08, 95% CI 0.67 to 1.74). No treatment-related side effects were reported in either group. We assessed the overall quality of the evidence as very low. We could not draw any definitive conclusions from this review about the effects of zinc supplementation on clinical outcomes of children with measles due to the very low quality of the evidence available. There is insufficient evidence to confirm or refute the effect of zinc supplementation in children with measles.

    Full Text Available This experiment was aimed to observe rumen fermentation kinetics of alternative supplements, i.e.Moringa oleifera and Peltiphyllum peltatum leaves added to maize silage diet as compared to aconventional supplement (barley-soya. A total of six treatments were investigated in the present study,which consisted of: maize silage (A, M. oleifera (B, P. peltatum (C, maize silage + concentrate (56:44,w/w; D, maize silage + M. oleifera (56:44, w/w; E, and maize silage + concentrate + P. peltatum(47:37:16, w/w/w; F. The feeds were incubated in vitro in three replicates (completely randomizedusing the Reading Pressure Technique system. Approximately 800 mg of the feeds were mixed by 75 mlof buffered rumen liquor. The incubation was carried out up to 12 h in bottles and gas pressure wasrecorded and released in regular intervals. Repeated sampling was conducted for analysis offermentation products at 1, 6 and 12 h of incubation period. The results showed that the nutritionalquality of Moringa and its fermentation pattern was comparable to that of barley-soya concentrate. PlainMoringa incubation resulted the highest production of iso-SCFA and soluble protein concentrationamong all treatments after 12 h incubation (P<0.05. Incubation of sole Peltiphyllum peltatum highlyhampered the fermentation rate. Production of iso-SCFA both for plain Peltiphyllum and its mixturewere comparatively low. Supplementation of Peltiphyllum increased significantly soluble proteinconcentration during 12 h incubation (P<0.05. Peltiphyllum also had a very low C2+C4/C3 ratiocompared to other treatments. It could be concluded that Moringa oleifera is a potential alternativesupplement to replace either partially or completely concentrate as a conventional supplement, andPeltiphyllum peltatum supplementation could reduce excessive protein degradation and fermentation ofthe concentrate in the rumen.

    Infection caused by HIV and malnutrition have a complex interaction and often coexist geographically. Malnutrition has synergistic immune effects and HIV affects nutritional status. HIV care and treatment programs are compelled to confront this dual burden to optimize HIV outcomes. In this article, we review the published literature concerning intervention studies in adults and children and the effect of food prices on HIV treatment programs. While the evidence base is relatively incomplete for specific macronutrient interventions in the context of HIV treatment, it is clear that a new standard of care is needed, guided by experience, rationale, and existing data, in which malnourished patients may easily access nutritional therapies within HIV treatment. From this clinical foundation, we may both treat patients and evaluate novel therapies. Some HIV care and treatment programs provide food-based supplements; however, rising food costs and economic instability may jeopardize the success of these programs. HIV treatment programs may struggle to meet the needs of patients with potential increased rates of malnutrition and food insecurity in the setting of high food prices.

Its evidences of use in other conditions remained insufficient and inconclusive.Conclusion: Melatonin therapy may be considered as efficacious and safe in insomnia and as an anti-oxidant; however, other roles needs to be evaluated in further studies.

  15. The Potential for Zinc Stable Isotope Techniques and Modelling to Determine Optimal Zinc Supplementation

    Directory of Open Access Journals (Sweden)

    2015-05-01

    Full Text Available It is well recognised that zinc deficiency is a major global public health issue, particularly in young children in low-income countries with diarrhoea and environmental enteropathy. Zinc supplementation is regarded as a powerful tool to correct zinc deficiency as well as to treat a variety of physiologic and pathologic conditions. However, the dose and frequency of its use as well as the choice of zinc salt are not clearly defined regardless of whether it is used to treat a disease or correct a nutritional deficiency. We discuss the application of zinc stable isotope tracer techniques to assess zinc physiology, metabolism and homeostasis and how these can address knowledge gaps in zinc supplementation pharmacokinetics. This may help to resolve optimal dose, frequency, length of administration, timing of delivery to food intake and choice of zinc compound. It appears that long-term preventive supplementation can be administered much less frequently than daily but more research needs to be undertaken to better understand how best to intervene with zinc in children at risk of zinc deficiency. Stable isotope techniques, linked with saturation response and compartmental modelling, also have the potential to assist in the continued search for simple markers of zinc status in health, malnutrition and disease.

    For a parotid gland irradiation technique with a pair of oblique wedged photon beams the target coverage near the surface was investigated. The planning target volume extends to 5 millimetres under the skin; a minimum target dose of 95% is required when the dose at the centre is set to 100%. The treatment technique was simulated on a water phantom with a beam of 45 degree gantry angle, 55 degree wedge, 8 x 10 cm{sup 2} field size and the isocentre at 2 cm depth. Beam energies of 4, 6 and 8 MV were used. The dose distributions were measured in two orthogonal planes through the isocentre perpendicular to the water surface with p-type silicon diodes along lines through the isocentre every 45 degrees. Dose distributions were calculated in these planes with our 3-D planning system (U-Mplan, University of Michigan planning system), with model parameters are fitted to depth dose curves and profiles of open and wedged normally incident beams. The location of the 95% isodose was determined in five points near the surface. For 4, 6 and 8 MV the depths of the 95% isodose were 6.0, 10.3 and 11.0 mm, respectively. The depths of the 95% points of single normally incident open fields were 6.0, 9.0 and 11.5 mm, respectively. The treatment planning system (TPS) calculated the 95% isodose for the parotid technique at 5.5, 7.3 and 11.5 mm depths, for 4, 6 and 8 MV, respectively. Thus for 6 MV the 95% was 3 mm deeper than calculated by the TPS; 2 mm were caused by the inaccuracy of the open field depth dose curve fit in the build-up region. The depth near the surface of the 95% isodose for this treatment technique can be estimated from single open field depth dose curves with acceptable accuracy. This result is not obvious because the effects of the wedge and oblique incidence on the dose distribution are also involved. The TPS performed well for the 4 and 8 MV beams, but for treatments with 6 MV target under dosage could have remained undetected. (Abstract Truncated)

    With the recent growth in the use of dietary supplements, it is increasingly important for clinicians to be familiar with the evidence for and against their efficacy. We set out to systematically review the dietary supplements available for the prevention and treatment of coronary artery disease. Between May 2004 and May 2006, we searched MEDLINE, the Cochrane Library, and Pro-Quest using the MeSH terms hypertension, hypercholesterolemia, myocardial infarction, dietary supplements, and herb-drug interactions. The MeSH terms of individual supplements identified were then added to the search. Reference lists of pertinent papers were also searched to find appropriate papers for inclusion. We included randomized controlled trials published in English of at least 1 week's duration that studied the efficacy of supplements in the treatment of hypercholesterolemia, or hypertension, or in the prevention of cardiac events. Qualifying papers were identified and assigned a Jadad quality score. In areas of uncertainty, a second investigator independently scored the trial. Fifteen (15) supplements were identified. Of these, most had little data available and most of the data were of poor quality. The supplements with the most supporting data were policosanol and garlic, both for hyperlipidemia. A growing body of literature exists for numerous supplements in the prevention of coronary artery disease, but much of these data are inconclusive. Clinicians should become familiar with the extent and limitations of this literature so that they may counsel their patients better.

    Full Text Available Introduction: Diarrheal diseases are a serious health problem and important causes of growth retardation and death in the developing world, especially those of prolonged duration. Since diarrhea is constantly found in children with zinc deficiency, very studies supported zinc supplements beneficial on the duration and severity of diarrhea among children. We review the impact of zinc effects on diarrhea in South-West Asia to update the evidences and to assess its effect on the global burden of diarrhea.   Materials and Methods: We conduct a systematic review through January 2014, for randomized controlled trials relevant to effect of zinc on diarrhea in children. We searched the MeSH terms zinc, acute gastroenteritis and children from various databases of Cochrane Library and PubMed, then clinical trials done in South-West Asia, selected for making written. Results: In recent years, several studies have reported the therapeutic effect of zinc supplementation on diarrheal diseases that was beneficial on decreased episode duration, stool output, stool frequency, hospitalization duration. In some countries in West Asia such as Lebanon, Israel, Saudi Arabia and Iran in clinical trials showed a faster improvement in acute gastroenteritis in children less than five years. But in some countries, such as Turkey, this effect was not significant.   Conclusions: Oral zinc supplementation significantly decreases diarrhea duration and has a greater effect on malnourished children. Zinc supplementation seems to be an appropriate public health strategy, mainly in areas of endemic deficiencies. Global attempts should is increased to support recommended regimen of therapeutic zinc by WHO in all areas. Keywords: Acute Gastroenteritis, Children, Zinc, South-West Asia.

    Interventional bronchoscopy has a predominant role in the management of both early and advanced-stage airway tumors. Given the very poor prognosis of lung cancer, there is a need for new tools to improve early detection and bronchoscopic treatment of endo-bronchial precancerous lesions. In more advanced stages, interventional bronchoscopy plays an important role, as nearly a third of lung cancers lead to proximal airway obstruction. This will cause great discomfort or even life-threatening symptoms related to local extension, such as dyspnea, post-obstructive pneumonia, and hemoptysis. Surgery for very locally advanced disease is only effective for a limited number of patients and the effects of conventional antitumor therapies, like radiation therapy or chemotherapy, are inconstant and are too delayed in a palliative context. In this review, we aim to provide pulmonologists with an exhaustive technical overview of (I) the bronchoscopic management of benign endobronchial lesions; (II) the bronchoscopic management of malignant tumors, including the curative treatment of localized lesions and palliative management of malignant proximal airway stenosis; and (III) descriptions of the emerging endoscopic techniques used to treat peripheral lung tumors.

    Full Text Available Abstract Background Obesity is a common pathology with increasing incidence, and is associated with increased mortality and healthcare costs. Several treatment options for obesity are currently available ranging from behavioral modifications to pharmaceutical agents. Many popular dietary supplements claim to enhance weight loss by acting as metabolic stimulators, however direct tests of their effect on metabolism have not been performed. Purpose This work identified the effects popular dietary supplements on metabolic rate and mitochondrial biosynthesis in human skeletal muscle cells. Methods Human rhabdomyosarcoma cells were treated with popular dietary supplements at varied doses for 24 hours. Peroxisome proliferator-activated receptor coactivator 1 alpha (PGC-1α, an important stimulator of mitochondrial biosynthesis, was quantified using quantitative reverse transcriptase polymerase chain reaction (qRT-PCR. Mitochondrial content was measured using flow cytometry confirmed with confocal microscopy. Glycolytic metabolism was quantified by measuring extracellular acidification rate (ECAR and oxidative metabolism was quantified by measuring oxygen consumption rate (OCR. Total relative metabolism was quantified using WST-1 end point assay. Results Treatment of human rhabdomyosarcoma cells with dietary supplements OxyElite Pro (OEP or Cellucore HD (CHD induced PGC-1α leading to significantly increased mitochondrial content. Glycolytic and oxidative capacities were also significantly increased following treatment with OEP or CHD. Conclusion This is the first work to identify metabolic adaptations in muscle cells following treatment with popular dietary supplements including enhanced mitochondrial biosynthesis, and glycolytic, oxidative and total metabolism.

    Full Text Available Objective: Infertility affects 15% of couples in fertile age. Male factor is a cause of infertility in almost half of cases, mainly due to oligoasthenoteratozoospermia (OAT. The purpose of this study is to review the effects of nutritional supplements as medical treatment for idiopathic male infertility. Material and methods: A Pub Med and Medline review of the published studies utilizing nutritional supplements for the treatment of male infertility has been performed. Results: Clinical trials on Vitamin E, Vitamin A, Vitamin C. Arginine, Carnitine, N-Acetyl-Carnitine, Glutathione, Coenzyme Q10, Selenium and Zinc were reviewed. Although there is a wide variability in selected population, dose regimen and final outcomes, nutritional supplements both alone and in combination seems to be able to improve semen parameters (sperm count, sperm motility and morphology and pregnancy rate in infertile men. Conclusions: There are rising evidences from published randomized trials and systematic review suggesting that nutritional supplementation may improve semen parameters and the likelihood of pregnancy in men affected by OAT. This improvement, however, is not consistent and there is a wide variation in the treatment regimens used. Well designed and adequately powered RCTs are needed to better clarify the role of nutritional supplements as treatment for male infertility.

    Despite efforts by many dietary supplements' manufactures to reduce or replace ethanol, many products containing ethanol in concentrations up to 70% are available on market. Furthermore, botanical dietary supplements can vary in metal content as a function of the environment, processing equipment and product containers. Therefore, the aim of study was to develop a new rapid and highly sensitive method for simultaneous determination of ethanol and its impurities in dietary supplements by sHSS-GC-FID technique. In addition, contamination with metals by GFAAS technique was evaluated. The proposed sHSS-GC-FID method was successfully applied for analysis of 93 samples containing various amounts of ethanol. It should be highlighted that the dramatic variation from manufacture's claims was found in even one third of products. Furthermore, high amounts of ethanol were found in several products especially designed for children and in one product labeled as "alcohol-free". Metal impurities were below the limits established by USP.

    2016-12-01

    Fertility treatment strategies are evolving, with a more rapid transition to assisted reproductive technology (ART) treatments after unsuccessful non-ART treatments. This trend increases the potential importance of adjuvant treatments in non-ART cycles, such as steroid hormone supplementation. It has been established that success rates of ART treatments are increased with the use of luteal support with progesterone. In the setting of non-ART cycles, however, the evidence is less clear, and clinical practices vary widely between providers and clinics. In this review, we aimed to provide an overview of the current evidence for the use of steroid hormone supplementation, including progesterone for luteal support, estrogens, androgens, and mineralocorticoids, in the setting of non-ART treatments for ovulatory women.

    Full Text Available Abstract Background Addition of sugar syrups to the basic wort is a popular technique to achieve higher gravity in beer fermentations, but it results in dilution of the free amino nitrogen (FAN content in the medium. The multicomponent protease enzyme Flavourzyme has beneficial effect on the brewer's yeast fermentation performance during high gravity fermentations as it increases the initial FAN value and results in higher FAN uptake, higher specific growth rate, higher ethanol yield and improved flavour profile. Results In the present study, transcriptome and metabolome analysis were used to elucidate the effect on the addition of the multicomponent protease enzyme Flavourzyme and its influence on the metabolism of the brewer's yeast strain Weihenstephan 34/70. The study underlines the importance of sufficient nitrogen availability during the course of beer fermentation. The applied metabolome and transcriptome analysis allowed mapping the effect of the wort sugar composition on the nitrogen uptake. Conclusion Both the transcriptome and the metabolome analysis revealed that there is a significantly higher impact of protease addition for maltose syrup supplemented fermentations, while addition of glucose syrup to increase the gravity in the wort resulted in increased glucose repression that lead to inhibition of amino acid uptake and hereby inhibited the effect of the protease addition.

    2016-01-01

    Vitamin D, important for maintaining bone health in Crohn's disease (CD), may have potential as a treatment for the core inflammatory disease process. There is plausible evidence in favor of vitamin D as an anti-inflammatory from animal models, epidemiological and cross sectional studies of CD. Few clinical trials, however, have been published and therefore the translation of this promise into clinical benefit for people with CD remains unclear. The purpose of this piece is to consider the viability of vitamin D as a treatment for CD based on the current available evidence.

    Radiation therapy for pediatric patients often includes the use of intravenous anesthesia with supplemental oxygen delivered via the nasal cannula. Here, we describe the use of an adaptive anesthesia technique for electron irradiation of the right naris in a preschool-aged patient treated under anesthesia. The need for an intranasal bolus plug precluded the use of standard oxygen supplementation. This novel technique required the multidisciplinary expertise of anesthesiologists, radiation therapists, medical dosimetrists, medical physicists, and radiation oncologists to ensure a safe and reproducible treatment course.

    synergistic effect in the inactivation of coliphage MS-2 and poliovirus. Other techniques: There are a number of other techniques. We have conducted trials of most of these in the control of Legionella sp., but these fall out of the scope of this article, and as such less emphasis has been placed on them here. Ozonation: Ozone [O3] is an oxidising gas, generated electrically from oxygen [O2]. L. pneumophila can be killed at ozone [Edelstien et al 1982]. Muraca et al [1987] found that 1-2 mg/L of continuous ozone over a six hour contact time, produced a 5 logarithm decrease of L. pneumophila. The effectiveness of ozone treatment against a range of bacteria and coliphages has been studied Botzenhart et al [1993]. E. coli was least resistant to ozone, followed by MS 2-coliphage and PhiX 174-coliphage, with L. pneumophila and Bacillus subtilis spores being the most resistant. (ABSTRACT TRUNCATED)

    2013-01-01

    We evaluated the effects of neutral detergent soluble fiber (NDSF) and sucrose supplementation on ruminal fermentation, microbial synthesis, and populations of ruminal cellulolytic bacteria using the rumen simulation technique (RUSITEC). The experiment had a 2×2 factorial design with two dosages of sucrose, low (ca. 0.26 g d-1, low-sucrose) and high (ca. 1.01 g d-1, high-sucrose), and two dosages of supplied NDSF, low (1.95 g d-1, low-NDSF) and high (2.70 g d-1, high-NDSF). Interactions between NDSF and sucrose were detected for xylanase activity from solid fraction and apparent disappearance of neutral detergent fiber (NDF) and hemicellulose, with the lowest values observed for high-NDSF and high-sucrose treatment. Supplemental NDSF appeared to increase the molar proportion of acetate and reduce that of butyrate;however, the effects of supplemental sucrose on VFA profiles depended upon NDSF amount. There was a NDSF×sucrose interaction for the production of methane. High-NDSF fermenters had lower ammonia-N production, greater daily N flow of solid-associated microbial pellets and total microorganisms, and greater microbial synthesis efficiency compared with low-NDSF fermenters. Supplementation with NDSF resulted in an increase in 16S rDNA copies of Ruminococcus flavefaciens and a reduction in copies of Ruminococcus albus. Supplementation with sucrose tended to increase the 16S rDNA copies of R. albus from liquid fraction, but did not affect daily total microbial N flow and cellulolytic bacterium populations from solid fraction. These data indicate that the effects of the interaction between NDSF and sugars on ruminal fermentation and fiber digestion should be taken into account in diet formulation. Ruminal fermentation and metabolism of sugars warrant further investigation.

    Full Text Available Oxidative stress has been implicated in various pathologies, including hypertension, atherosclerosis, diabetes, and chronic renal disease. The current work was designed with the aim of investigating the potentials of antioxidants copper, manganese, and zinc in the treatment of hypertension in Wistar rats. The rats were fed 8% NaCl diet for 5 weeks and treatment with supplements in the presence of the challenging agent for additional 4 weeks. The supplementation significantly decreased the blood pressure as compared with hypertensive control. The result also indicated significant decreased in the levels of total cholesterol, triglyceride, low-density lipoprotein cholesterol and very low-density lipoprotein cholesterol, malondialdehyde, insulin and increase in the high-density lipoprotein cholesterol, total antioxidant activities, and nitric oxide of the supplemented groups relative to the hypertensive control. The average percentage protection against atherogenesis indicated 47.13 ± 9.60% for all the supplemented groups. The mean arterial blood pressure showed significant positive correlation with glucose, total cholesterol, triglyceride, low-density lipoprotein cholesterol, very low-density lipoprotein cholesterol, atherogenic index, insulin resistance and malondialdehyde while high density lipoprotein-cholesterol and total antioxidant activities showed negative correlation. The result therefore indicated strong relationship between oxidative stress and hypertension and underscores the role of antioxidant minerals in reducing oxidative stress, dyslipidemia, and insulin resistance associated with hypertension.

    We aimed to investigate the impact of various varicocelectomy techniques and/or L-carnitine as an adjunct treatment, following the emergence of oxidative stress, on the expression levels of SCF/c-kit signalling pathways in spermatogenesis. Forty-two rats were divided into seven groups: group 1 (G1) control; group 2 (G2) sham; group 3 (G3) varicocele; group 4 (G4) varicocele + varicocelectomy with testicular nonartery sparing; group 5 (G5) same as G4 but with artery sparing; group 6 (G6) same as G4 but with L-carnitine and group 7 (G7) same as G5 with L-carnitine. mRNA expression levels of SCF and c-kit were measured quantitatively using real-time polymerase chain reaction. CASP-3 activity at protein level was determined, and histological evaluation was performed. mRNA expression level of SCF increased in G6 as compared to control group (3.52-folds change; P = 0.035), whereas mRNA expression level of c-kit gene remained the same. We found that in the left testis of G6 group, mRNA expression level of SCF increased 2.2-folds in comparison with the right testis (P carnitine may be considered as supportive treatment regimes in addition to conventional surgical treatments.

    Full Text Available Background: Fatty acids play various physiological roles in the organism; they are crucial for the structure of cell membranes, metabolic processes, transmission of nerve impulses and brain functions. In recent years, particular attention has been paid to the rich sources of omega-3 for the treatment of many diseases, especially mental illnesses. The present study aimed to investigate the effects of omega-3 supplement in the treatment of patients with bipolar I disorder (BID. Methods: In this double-blind clinical trial, 100 patients suffering from BIDs were randomly divided into two, i.e. control (n = 50 and experimental (n = 50 groups. In addition to the other standard treatments, 1000 mg of omega-3 supplement was given to the experimental group on daily basis for 3 months and placebo was given to the control group. The Young Mania Rating Scale was completed for both groups before and after the intervention. Afterward, data were analyzed using paired t-test, independent t-test, and Chi-square test. Results: Before intervention, mean severity of mania in the experimental group (23.50 ± 7.02 and control group (23.70 ± 8.09 was not significant (P ≤ 0.89. The difference after the intervention in the experimental group (10.64 ± 3.3 and control group (20.12 ± 6.78 was significant (P < 0.01. The mean intensity of mania before (23.50 ± 7.02 and after (10.64 ± 3.3 intervention reported to be significant at P < 0.05. Conclusions: Since omega-3 supplement was effective for the treatment of BID, it is suggested to use omega-3 supplements as an adjuvant therapy along with the other pharmacotherapies.

  2. Antioxidant supplementation during oncology treatment has no effect on cervical cancer recurrence

    Karolina Álvarez-Altamirano

    Full Text Available Introduction and aim: Antioxidant therapy with chemotherapy and radiotherapy in cervical cancer patients is controversial. While some evidence suggests that the use of antioxidants diminishes side effects from anticancer therapy, there is also data to suggest that antioxidants increase the risk of recurrence by affecting oncology treatments. Methods: We conducted a controlled clinical trial in cervical cancer patients supplemented with an antioxidant mixture or a placebo during four years after their antineoplastic treatment was completed and the effect on recurrence. We also conducted data on used hemoglobin and albumin levels. Differences between groups were analyzed using chi-square test. Survival was calculated by the Multivariate COX regression with omnibus test and the enter method. Results: 103 treated patients were in clinical stages IIB and IIIB of cervical cancer, 48% (n = 49 of the patients were treated with antioxidant supplementation and 52% (n =54 of the patients were in the placebo group. Of the original 103 patients, were able to follow up on 88 patients for an additional four years.23.9% (n = 21 of the patients presented cancer recurrence and 76.1% (n = 67 did not, 21.6% (n = 19 patients showed metastasis. 8% (n = 7 patients were in the antioxidant group and 15.9% (n = 14 were in the placebo group (p > 0.05. Regarding implications of cancer survivors, antioxidant supplementation apparently seems not to have interference with recurrence in cervical cancer patients but there is not enough evidence to prove it. A different dosage may have the expected effect; however, further studies with another dosage and criteria are necessary. Conclusions: Supplementation with antioxidants during treatment of cervical cancer has no effect on cancer recurrence after 4 years of follow-up.

    The concentrations of mercury in forty, commercially available dietary supplements, were determined using a new, inexpensive analysis technique. The method involves thermal decomposition, amalgamation, and detection of mercury by atomic absorption spectrometry with an analysis time of approximately six minutes per sample. The primary cost savings from this approach is that labor-intensive sample digestion is not required prior to analysis, further automating the analytical procedure. As a result, manufacturers and regulatory agencies concerned with monitoring lot-to-lot product quality may find this approach an attractive alternative to the more classical acid-decomposition, cold vapor atomic absorption methodology. Dietary supplement samples analyzed included astragalus, calcium, chromium picolinate, echinacea, ephedra, fish oil, ginger, ginkgo biloba, ginseng, goldenseal, guggul, senna, St John's wort, and yohimbe products. Quality control samples analyzed with the dietary supplements indicated a high level of method accuracy and precision. Ten replicate preparations of a standard reference material (NIST 1573a, tomato leaves) were analyzed, and the average mercury recovery was 109% (2.0% RSD). The method quantitation limit was 0.3 ng, which corresponded to 1.5 ng/g sample. The highest found mercury concentration (123 ng/g) was measured in a concentrated salmon oil sample. When taken as directed by an adult, this product would result in an approximate mercury ingestion of 7 mug per week.

    This Special Supplement presents reports from working groups meeting at the Fourth Kraepelin Symposium in Munich, Germany, in September 2014. It covers the origins and therapy of cognitive dysfunction in schizophrenia. Cognitive deficits are core symptoms of schizophrenia being decisive for the long-term prognosis only improved moderately by antipsychotic treatment, however, showing more evidence for cognitive remediation. The authors refer to neurobiological and psychological underpinnings of cognitive deficits and to innovative treatment interventions aimed at improving cognitive dysfunction in order to improve outcome and to support coping with the illness. Therapeutic approaches include aerobic exercise, cognitive training, psychoeducation, cognitive therapy, noninvasive brain stimulation and pharmacotherapy in acute to post-acute patients. The supplement also presents novel diagnostic tools for early recognition, such as biomarkers, as well as cognitive training to prevent worsening of symptoms in individuals at clinical high risk for psychosis. In recent years there has been progress in basic science and outcomes research as well as psychopharmacological and psychological treatment options. Despite of this, treatment of cognitive deficits needs significant improvement and further research is needed. © The Author 2016.

    2016-01-01

    Shifts in microbial populations of the intestinal tract have been associated with a multitude of nutritional, autoimmune, and infectious diseases. The limited diversity following antibiotic treatments creates a window for opportunistic pathogens, diarrhea, and inflammation as the microbiome repopulates. Depending on the antibiotics used, microbial diversity can take weeks to months to recover. To alleviate this loss of diversity in the intestinal microbiota, supplementation with probiotics has become increasingly popular. However, our understanding of the purported health benefits of these probiotic bacteria and their ability to shape the microbiome is significantly lacking. This study examined the impact of probiotics concurrent with antibiotic treatment or during the recovery phase following antibiotic treatment of mice. We found that probiotics did not appear to colonize the intestine themselves or shift the overall diversity of the intestinal microbiota. However, the probiotic supplementation did significantly change the types of bacteria which were present. In particular, during the recovery phase the probiotic caused a suppression of Enterobacteriaceae outgrowth (Shigella and Escherichia) while promoting a blooming of Firmicutes, particularly from the Anaerotruncus genus. These results indicate that probiotics have a significant capacity to remodel the microbiome of an individual recovering from antibiotic therapy.

    Previous studies have shown that aspirin is used in colon cancer treatment. However, long-term of Aspirin usage is limited to gastric and renal toxicity. Luteolin (LUT) has cancer prevention and anti-inflammatory effects. The present study was designed to investigate the effect of LUT supplementation and Aspirin treatment in dimethylhydrazine (DMH)-induced carcinogenesis in rats. DMH (20 mg/kg BW/week) treated rats received gavages with Aspirin (50 mg/kg BW/week) and LUT (0.2 mg/kg BW/day) for 15 weeks. DMH injections induce colon polyps and renal bleeding, significantly increasing carcinoembryonic antigen (CEA), cyclooxygenase-2 (COX-2), oxidative stress, and kidney function tests and reducing antioxidant markers. Either Aspirin or LUT gavages alone or combined produce a significant decrease in colon polyp number and size, significantly decreasing CEA, COX-2, and oxidative stress and increasing antioxidant markers. In conclusion, the supplementations of LUT adjacent to Aspirin in the treatment of DMH-induced carcinogenesis in rats reflect a better effect than the use of Aspirin alone.

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    Objective The effect of intermittent iron supplementation weekly and twice weekly was studied in children with iron deficiency anemia(IDA). Methods Subjects were 58 children who were randomly divided into two groups. One group received a dosage of 2mg/kg Fe every 3d for 9 weeks. The other group received the same dose Fe once a week for 12 weeks. Results Hemoglobin and serum ferritin increased significantly after treatment in both groups (P <0.05), and zinc protoporphyrin decreased significantly (P <0. 05). But serum ferritin of both groups was different after 6 weeks of treatment (P <0. 01). The side effect of the group supplemented once every 3d was higher than that of the group once a week, but there was no statistically significant difference. Conclusion Iron sup plementation every 3d has a similar effect to once a week for treatment of IDA. The former should be used for the se rious patients for 6 weeks. The later should be used for infants and the patients whose resistance of intestines and stomach are not good.

    One hundred and five Labrador dogs were randomly divided into two groups to determine the number of animals that develop elbow dysplasia when treated with an oral supplement compared to untreated ones. Efficacy of the oral treatment was also evaluated once illness was diagnosed. The supplement (Hyaloral) contained hyaluronic acid, hydrolysed collagen, glucosamine, chondroitin sulphate, and gamma oryzanol. Clinical evaluation of the elbow joints was completed at months 3, 6, 12, and 20 by orthopaedic evaluations, radiography, serologic and blood analysis, and veterinarian evaluation of dysplasia symptoms. All side effects were recorded. In the control group, 33.3% of the dogs developed radiographic evidence of elbow dysplasia compared to 18.5% in the treated group. Symptoms of dysplasia at 12 months differed between the treated (12.5%) and control (61.5%) animals, and were significantly different at 20 months (p oral treatment with Hyaloral may have a potential cumulative action that provides protection against dysplasia and significantly improves symptoms of elbow dysplasia.

    Metabolic syndrome (MetS) comprises a clinical complex of patient risk factors, including increased waist circumference, high triglyceride levels, low high-density lipoprotein cholesterol level, high blood pressure, and insulin resistance, the presence of which increases the likelihood of developing diabetes and cardiovascular disease. With a quarter of the American adult population affected, MetS and type 2 diabetes mellitus have been referred to as the most significant public health threats of the 21st century. Lifestyle modification and weight loss are recommended, however, no specific pharmacologic treatment is known. Given that low levels of testosterone have been implicated in the pathogenesis of MetS and an inverse relationship exists between circulating testosterone levels and the development of MetS, it is tempting to speculate that men with MetS may benefit from testosterone supplementation therapy. As such, our review examines the role of testosterone and the use of testosterone supplementation therapy as a treatment in men with MetS.

    Background: Systemic treatment with propranolol is proven to be effective for patients with hemangiomas with less side-effect. We used a propranolol gel for topical use on hemangiomas. Methods: In this retrospective study, we analyzed 148 patients who had been treated topically with propranolol gel for 12 weeks. We analyzed the data of patients and clinically gave each hemangioma a "hemangioma score" to determine the treatment success. Results: In 147 of the 148 patients, strong signs of resolution under treatment included lightening, paling, and less vascularization. The hemangioma score showed a signifi cant decrease during the treatment. Relevant serum levels of propranolol were not found. Adverse effects were rare and not related to propranolol. Conclusion: Topical treatment with propranolol gel is suitable for specific hemangiomas in addition to cryotherapy and systemic treatment with propranolol.

    From May, 2000 to June, 2001, 27 patients with Parkinson disease (PD), including 10cases of rigidity, 13 cases of tremor, 4 cases of rigidity and tremor, were treated by microelectrodeguided technique. Among them, phlebotomy was carried out in 17 cases and thalamotomy in 10 cases. All the targets of lesion were anatomically located by using MR and neurophysiological signals on microelectrode. Our results showed that the efficiency of microelectrode-guided technique for treatment of PD was 98 %. The postoperative unified parkinson disease rating scale were 12.3+ 9.1 and 13. 2± 8. 9 respectively, which significantly improved as compared with those before operation. It was concluded that by recognizing special electrical signals in neurons microelectrode-guided neuropsychological techniques can locate target at cellular level, which overcomes the individual difference in anatomy and function, and allow more accuracy, safety and efficiency of operation. This is especially true of PD patients who fail to respond to medical treatment.

    Full Text Available Thoracic endovascular aortic repair (TEVAR is increasingly used in the treatment of acute type B aortic dissection. Type Ia endoleaks are a common complication of the procedure, but its clinical significance as well as the best treatment strategy remain poorly defined. We present a case of a type Ia endoleak following TEVAR in the treatment of acute type B aortic dissection. Chimney technique approach was used in an attempt to seal the endoleak. Although technical success was suboptimal, the patient remained clinically stable and event free. Data regarding the natural course and management of type Ia endoleaks following TEVAR for aortic dissection are sparse. Future research is required to establish the clinical and technical determinants of the need to treat these endoleaks as well as the best treatment strategy.

    Biologically-based spray treatments, including nucleopolyhedroviruses, neem, and spinosad, were evaluated as supplemental controls for the fall armyworm, Spodoptera frugiperda (J. E. Smith), and corn earworm, Helicoverpa zea (Boddie) (Lepidoptera: Noctuidae), on transgenic sweet corn, Zea mays (L.) (Poales: Poaceae), expressing a Cry1Ab toxin from Bacillus thuringiensis Berliner (Bacillales: Bacillaceae) (Bt). Overall, transgenic corn supported lower densities of both pests than did nontransgenic corn. Control of the fall armyworm was improved in both whorl-stage and tassel-stage corn by the use of either a nucleopolyhedrovirus or neem, but the greatest improvement was seen with spinosad. Only spinosad consistently reduced damage to ears, which was caused by both pest species. In general, efficacy of the spray materials did not differ greatly between transgenic and nontransgenic corn.

    The primary goal of treatment in children with early onset scoliosis (EOS) is to control the deformity and to allow spinal and chest wall growth to continue and improve pulmonary function. In skeletally immature children spondylodesis leads to fusion of the instrumented segments with associated nonsymmetrical growth and pulmonary insufficiency. Non-fusion, techniques such as growing rods, vertical expandable prosthetic titanium rib® (VEPTR) and staples have evolved over the past years. Each technique has its different spectrum of indications which the surgeon has to follow accurately to prevent the patient from developing complications. A new trend started by using magnetically controlled growing rods to avoid the need for anesthesia and open surgery during adaptive growth. The intention of this article is to give the reader a synopsis about the three most important non-fusion techniques based on own experience and the current literature.

    In order to accelerate waste treatment and disposal of Hanford tank waste by 2028, the Department of Energy (DOE) and CH2M Hill Hanford Group (CHG), Inc. are evaluating alternative technologies which will be used in conjunction with the Waste Treatment Plant (WTP) to safely pretreat and immobilize the tank waste. Several technologies (Bulk Vitrification and Steam Reforming) are currently being evaluated for immobilizing the pretreated waste. Since the WTP does not have sufficient capacity to pretreat all the waste going to supplemental treatment by the 2028 milestone, two technologies (Selective Dissolution and Fractional Crystallization) are being considered for pretreatment of salt waste. The scope of this task was to: (1) evaluate the recent Savannah River Site (SRS) Tank 41 dissolution campaign and other literature to provide a more complete understanding of selective dissolution, (2) provide an update on the progress of salt dissolution and modeling activities at SRS, (3) investigate SRS experience and outside literature sources on industrial equipment and experimental results of previous fractional crystallization processes, and (4) evaluate recent Hanford AP104 boildown experiments and modeling results and recommend enhancements to the Environmental Simulation Program (ESP) to improve its predictive capabilities. This report provides a summary of this work and suggested recommendations.

    Approximately half of those receiving treatment for an alcohol use disorder (AUD) also suffer with an anxiety or depressive (internalizing) disorder. Because all internalizing disorders mark a poor alcohol treatment outcome, it seems reasonable to supplement AUD treatment with a psychiatric intervention when these disorders co-occur with AUD. However, this conclusion may be faulty given that the various possible interrelationships between AUD and internalizing disorders do not uniformly imply a high therapeutic yield from this approach. Unfortunately, the studies conducted to date have been too few and too small to resolve this important clinical issue with confidence. Therefore, we used a meta-analytic method to synthesize the effects from published randomized controlled trials examining the impact of supplementing AUD treatment with a psychiatric treatment for co-occurring internalizing disorder (N = 15). We found a pooled effect size (d) of .32 for internalizing outcomes and .22 for a composite of alcohol outcomes; however, the alcohol outcomes effect sizes were greater than this for some specific outcome domains. Subgroups that differed in terms of internalizing outcomes included treatment type (medication vs. cognitive behavioral therapy) and treatment focus (anxiety vs. depression). There was also a trend for the studies with better internalizing disorder outcomes to have better alcohol outcomes. These results indicate that clinical outcomes (both psychiatric and alcohol-related) could be somewhat improved by supplementing AUD treatment with psychiatric treatment for co-occurring internalizing disorder.

    This report describes the Yakima Fisheries Project facilities (Cle Elum Hatchery and acclimation satellites) which provide the mechanism to conduct state-of-the-art research for addressing questions about spring chinook supplementation strategies. The definition, descriptions, and specifications for the Yakima spring chinook supplementation program permit evaluation of alternative fish culture techniques that should yield improved methods and procedures to produce wild-like fish with higher survival that can be used to rebuild depleted spring chinook stocks of the Columbia River Basin. The definition and description of three experimental treatments, Optimal Conventional (OCT), Semi-Natural (SNT), Limited Semi-Natural (LSNT), and the biological specifications for facilities have been completed for the upper Yakima spring chinook salmon stock of the Yakima Fisheries Project. The task was performed by the Biological Specifications Work Group (BSWG) represented by Yakama Indian Nation, Washington Department of Fish and Wildlife, National Marine Fisheries Service, and Bonneville Power Administration. The control and experimental variables of the experimental treatments (OCT, SNT, and LSNT) are described in sufficient detail to assure that the fish culture facilities will be designed and operated as a production scale laboratory to produce and test supplemented upper Yakima spring chinook salmon. Product specifications of the treatment groups are proposed to serve as the generic templates for developing greater specificity for measurements of product attributes. These product specifications will be used to monitor and evaluate treatment effects, with respect to the biological response variables (post release survival, long-term fitness, reproductive success and ecological interactions).

    Chronic groin pain in the athlete can be a difficult problem to manage. Adductor dysfunction is the most common cause of groin pain in athletes, with the adductor longus being the tendon most commonly involved. The most reproducible finding for adductor longus tendinopathy is tenderness along the tendon with passive abduction and resisted hip adduction in extension. Magnetic resonance imaging and injection of a corticosteroid and anesthetic into the proximal muscle-tendon junction are both helpful in confirming the diagnosis. Nonoperative treatment may consist of protected weight bearing, ice application, ultrasonography, electrical stimulation, and gentle stretching with progressive strengthening. However, nonoperative management is not always successful. In these instances, surgical treatment can be quite effective. We present the indications, surgical technique, and rehabilitation protocol of adductor tenotomy for chronic tendinopathy. This can prove a useful tool for the treatment of recalcitrant groin pain attributable to the adductor longus.

    In spring 2011, the Technology Maturation Plan (TMP) for the Supplemental Treatment Project (RPP-PLAN-49827, Rev. 0), Technology Maturation Plan for the Treatment Project (T4S01) was developed. This plan contains all identified actions required to reach technical maturity for a field-deployable waste feed pretreatment system. The supplemental pretreatment system has a filtration and a Cs-removal component. Subsequent to issuance of the TMP, rotary microfiltration (RMF) has been identified as the prime filtration technology for this application. The prime Cs-removal technology is small column ion exchange (ScIX) using spherical resorcinol formaldehyde (sRF) as the exchange resin. During fiscal year 2011 (FY2011) some of the tasks identified in the TMP have been completed. As of September 2011, the conceptual design package has been submitted to DOE as part of the critical decision (CD-1) process. This document describes the remaining tasks identified in the TMP to reach technical maturity and evaluates the validity of the proposed tests to fill the gaps as previously identified in the TMP. The potential vulnerabilities are presented and the completed list of criteria for the DOE guide DOE G 413.3-4 different technology readiness levels are added in an attachment. This evaluation has been conducted from a technology development perspective - all programmatic and manufacturing aspects were excluded from this exercise. Compliance with the DOE G 413.3-4 programmatic and manufacturing requirements will be addressed directly by the Treatment Project during the course of engineering design. The results of this evaluation show that completion of the proposed development tasks in the TMP are sufficient to reach TRL 6 from a technological point of view. The tasks involve actual waste tests using the current baseline configuration (2nd generation disks, 40 psi differential pressure, 30 C feed temperature) and three different simulants - the PEP, an AP-Farm and an S

    In the present study, the effects of long-term exogenous glucocorticoids administration and dietary supplementation of alpha-tocopheryl acetate on the induction of lipid peroxidation in skeletal muscle were investigated. Male broiler chicks were randomly assigned to 2 diet treatments: the basal diet supplemented with 20 (low level of vitamin E) or 200 (high level of vitamin E) mg of vitamin E (as DL-alpha-tocopheryl acetate)/kg of diet. At 35 d of age, the chickens in each dietary treatment were randomly divided into 3 groups of 30 chickens and subjected to the following treatments: daily s.c. injection of dexamethasone (DEX, 2 mg/kg of BW) for 6 d, sham injection of saline (control), or the sham-treated pair-fed control that maintained the same feed intake as DEX treatment (pair-control). The results showed that the growth of chickens was suppressed by DEX, whereas it was improved by the high level of vitamin E treatment. The DEX treatment resulted in augmented plasma concentrations of TBA reacting substances. Muscle TBA reacting substances levels were higher in DEX chickens at both 24- and 48-h time points postslaughter. Vitamin E supplementation suppressed the formation of lipid peroxidation in both plasma and skeletal muscle tissues. Muscle activity of superoxide dismutase was significantly increased by DEX treatment in both musculus pectoralis major and musculus biceps femoris and maintained as such during the initial 48 h postmortem. The result of the present study indicated that DEX treatment increased the saturation level of skeletal muscle fatty acids. These results suggest that vitamin E supplementation was favorable for the performance of broiler chickens by alleviating the oxidative stress induced by DEX treatment.

  20. Comparative study of novel endovascular treatment techniques for intracranial aneurysms

    Intracranial aneurysms are life-threatening vascular lesions, which are potentially treatable to avoid the consequences of their rupture. Current treatments, either surgical or endovascular, are all guided to reduce the hemodynamic forces acting on the aneurysm wall in an effort to minimize the risk of rupture. Surgical clipping is still the most used technique to treat this type of aneurysm but there is a continued demand for less invasive approaches. This has led to the development of several endovascular techniques. We report here a comparative study of the reduction in the hemodynamic stresses and the modification of the flow in the parent vessel resulting from the use of three different techniques. The first one consists of endosaccular packing with platinum coils (GDC, Target Therapeutics), which is already widely used but its long-term efficacy has not yet been determined. The second one consists of the embolization of the aneurismal sac with Onyx, a polymer which hardens when in contact with the blood (being developed by Micro Therapeutics, Inc.). The third one involves the packing of the sac with hydrocoils, platinum wires coated with a gel which quickly hydrates when in contact with blood (developed by MicroVention). A Digital Particle Image Velocimetry (DPIV) system is used to measure in vitro the velocity field inside a model of an ACOM aneurysm (an aneurysm forming in the anterior communicating artery). Physiological accurate pulsatile flow conditions are input to the arterial model through a programmable pump. The measurements show that although all treatment techniques lead to a reduction in both normal and tangential shear stresses on the aneurismal sac, each one of them also leads to different modifications of the flow in the parent vessel which may have consequences related to potential for clotting. Comparison of the untreated aneurysm with the above three treated cases also showed that the characteristics of the wall shear stresses on the parent

    Blanco, C E; Leon, H O; Guthrie, T B

    2001-05-01

    We describe a comprehensive approach to the endoscopic treatment of calcaneal spur syndrome developed by the Arthroscopic Group of the Orthopedic Service of Hospital Hermanos Ameijeiras in Havana, Cuba. The surgical technique involves treatment of the heel spur and plantar fasciitis commonly found in calcaneal spur syndrome, but it also addresses adjacent calcaneal periostitis and allows decompression of the nerve to the abductor digiti quinti. Medial endoscopy and lateral instrumentation are used in a sequential approach with exposure and debridement of the posterior roof of the calcaneal arch, followed by removal of the calcaneal spur, lateral to medial release of the medial 75% of the plantar fascia, and if necessary, debridement of the calcaneal tuberosity periosteum. This technique was used in a prospective case series from June 1997 to May 1998 to treat a select group of 38 feet in 30 patients who reported unacceptable levels of pain despite 5 months of conservative treatment, which included an aggressive 8-week physical therapy program prescribed by the treating physician. Good to excellent results were obtained at 3 months postoperatively in all patients with regard to pain relief and return to normal activity, although 5 patients required a short course of physical therapy to resolve symptoms brought on by sports, trauma, or impact loading before 1-year follow-up, at which time all patients reported good to excellent results. Complications included 3 superficial wound infections cured by oral antibiotics and 2 transient lateral paresthesias that resolved with rest and nonsteroidal inflammatory medications. The described technique may provide a useful method for treating refractory heel spur syndrome and warrants further study.

This study characterized dietary supplement use by male and female patients (n = 376 attending a periodontal clinic—information that is essential for evidence-based intervention studies that may improve patient outcomes after periodontal procedures. Calcium, vitamin D, multivitamin and vitamin C were most commonly used. A greater (p ≤ 0.05 number of males took no supplements compared to females, and more (p ≤ 0.05 females than males took ≥ four supplements. Females took more (p ≤ 0.05 calcium, vitamin D, fish oil, green tea, magnesium, omega 3,6,9 and B vitamin complex. Younger patients (31–50 years had the highest (p ≤ 0.05 frequency of no supplement use compared to older age groups. Patients over age 50 had a higher (p ≤ 0.05 frequency of using ≥ four supplements including calcium and vitamin D. Supplement use was lower (p ≤ 0.05 in smokers, particularly for calcium, fish oil, green tea and vitamin D. In conclusion, females, older individuals and non-smokers have higher supplement use. Future dietary intervention studies can focus on supplements with known biological activities—anti-inflammatory, antioxidant or osteogenic activity—that may enhance wound healing after reconstructive periodontal procedures.

    Full Text Available Abstract In this review, basic knowledge and recent innovation of surgical treatment for scoliosis will be described. Surgical treatment for scoliosis is indicated, in general, for the curve exceeding 45 or 50 degrees by the Cobb's method on the ground that: 1 Curves larger than 50 degrees progress even after skeletal maturity. 2 Curves of greater magnitude cause loss of pulmonary function, and much larger curves cause respiratory failure. 3 Larger the curve progress, more difficult to treat with surgery. Posterior fusion with instrumentation has been a standard of the surgical treatment for scoliosis. In modern instrumentation systems, more anchors are used to connect the rod and the spine, resulting in better correction and less frequent implant failures. Segmental pedicle screw constructs or hybrid constructs using pedicle screws, hooks, and wires are the trend of today. Anterior instrumentation surgery had been a choice of treatment for the thoracolumbar and lumbar scoliosis because better correction can be obtained with shorter fusion levels. Recently, superiority of anterior surgery for the thoracolumbar and lumbar scoliosis has been lost. Initial enthusiasm for anterior instrumentation for the thoracic curve using video assisted thoracoscopic surgery technique has faded out. Various attempts are being made with use of fusionless surgery. To control growth, epiphysiodesis on the convex side of the deformity with or without instrumentation is a technique to provide gradual progressive correction and to arrest the deterioration of the curves. To avoid fusion for skeletally immature children with spinal cord injury or myelodysplasia, vertebral wedge ostetomies are performed for the treatment of progressive paralytic scoliosis. For right thoracic curve with idiopathic scoliosis, multiple vertebral wedge osteotomies without fusion are performed. To provide correction and maintain it during the growing years while allowing spinal growth for

    Background. In this study, we examined whether UV-visible and fluorescence spectroscopy techniques detect the progression of atherosclerosis in serum of rabbits fed on high-cholesterol diet (HCD) and HCD supplemented with zinc (HCD + Zn) compared with the control. Methods. The control rabbits group was fed on 100 g/day of normal diet. The HCD group was fed on Purina Certified Rabbit Chow supplemented with 1.0% cholesterol plus 1.0% olive oil (100 g/day) for the same period. The HCD + Zn group was fed on normal Purina Certified Rabbit Chow plus 1.0% cholesterol and 1.0% olive oil supplemented with 470 ppm Zn for the same feeding period. UV-visible and fluorescence spectroscopy and biochemistry in Rabbit's blood serum and blood hematology were measured in Rabbit's blood. Results. We found that the fluorescent peak of HCD shifted toward UV-visible wavelength compared with the control using fluorescent excitation of serum at 192 nm. In addition, they showed that supplementation of zinc (350 ppm) restored the fluorescent peak closely to the control. By using UV-visible spectroscopy approach, we found that the peak absorbance of HCD (about 280 nm) was higher than that of control and that zinc supplementation seemed to decrease the absorbance. Conclusions. This study demonstrates that ultraviolet-visible and fluorescence spectroscopy techniques can be applied as noninvasive techniques on a sample blood serum for diagnosing or detecting the progression of atherosclerosis. The Zn supplementation to rabbits fed on HCD delays or retards the progression of atherosclerosis. Inducing anemia in rabbits fed on HCD delays the progression of atherosclerosis. PMID:24350281

    Full Text Available The textile industry uses the electrochemical techniques both in textile processes (such as manufacturing fibers, dyeing processes, and decolorizing fabrics and in wastewaters treatments (color removal. Electrochemical reduction reactions are mostly used in sulfur and vat dyeing, but in some cases, they are applied to effluents discoloration. However, the main applications of electrochemical treatments in the textile sector are based on oxidation reactions. Most of electrochemical oxidation processes involve indirect reactions which imply the generation of hypochlorite or hydroxyl radical in situ. These electrogenerated species are able to bleach indigo-dyed denim fabrics and to degrade dyes in wastewater in order to achieve the effluent color removal. The aim of this paper is to review the electrochemical techniques applied to textile industry. In particular, they are an efficient method to remove color of textile effluents. The reuse of the discolored effluent is possible, which implies an important saving of salt and water (i.e., by means of the “UVEC Cell”.

    The orthotopic rat liver transplant model is a widely used technique in transplantation research. It has many advantages over other animal transplant models because of its availability and low cost. However, it must be emphasized that success with the rat model requires thorough training. The aim of this paper is to describe the microsurgical technique involved in 60 rat liver transplants and to discuss the complications and their treatments. Forty-nine liver transplants were performed at the Experimental Laboratory of the University Hospital, Ontario, Canada (ELUH) and 11 were performed at the Laboratorio de Trasplante de Organos de la Facultad de Ciencias Médicas de La Plata, Buenos Aires. Argentina (LTO). Among the transplants performed at the ELUH, the observed complications were haemorrhage (n = 4), pneumothorax (n = 1), anastomotic failure (n = 15), bile leak (n = 3), and bile duct necrosis (n = 9). The remaining 17 rats at the ELUH were healthy at day 7 after surgery. Animal survival immediately postop, at 24 hours postop and at 7 days postop was achieved with the 9th, 20th and 21st transplants respectively. At the LTO, 3 rats died as a result of anaesthetic complications. Seven-day animal survival was achieved with the 11th transplant. We beleive that the description of the orthotopic rat liver transplantation technique, as well as the discussion regarding complications and their management, can be useful for researchers interested in performing liver transplantation in rats.

    Early-onset bipolar disorder has significant morbidity and mortality. Development of safe, effective treatments to which patients will adhere is critical. Pharmacologic interventions for childhood bipolar spectrum disorders are limited and are associated with significant risk for adverse events. Diet and nutrition research suggests vitamins, minerals, and other nutrients are important underpinnings of general physical and mental health; furthermore, they may even be useful in treating mood dysregulation by providing a more favorable risk-benefit ratio than contemporary psychotropic agents. This article reviews the literature on multinutrient supplementation and mental health, and examines a case study of a 12-year-old boy with bipolar disorder and co-morbid diagnoses treated for 6 years with conventional medication and finally a multinutrient supplement. The multinutrient supplement in this case study is EMPowerplus (EMP+), a 36-ingredient supplement containing 16 minerals, 14 vitamins, 3 amino acids, and 3 antioxidants. It was used to treat a 12-year-old boy initially diagnosed with bipolar disorder not otherwise specified (BP-NOS) at age 6, and whose diagnosis evolved by age 10 to bipolar I (BP-I), mixed, with psychotic features. He also met criteria for generalized anxiety disorder by age 8 and obsessive-compulsive disorder by age 10. After 6 years of conventional treatment (ages 6-12), he received 14 months of EMP+. Symptom manifestation over 7 years is described in conjunction with treatment history. EMP+ resulted in outcome superior to conventional treatment. This report adds to accumulating preliminary evidence that further basic science and clinical studies of multinutrient supplements are warranted.

    Sixty-six cases of hemangioma were treated with CO2 laser alone (22 cases as a control group), or CO2 laser supplemented with He-Ne laser (44 cases of the treated group). Optimum power dosage was first sought on normal volunteers. Arteriolar vasculature and lymphatics were blocked 3 - 5 times with procaine hydrochloride (5:1) to minimize local blood congestion. Results show that the healing rate of the treated group was significantly higher than that of the control group (X3 equals 3.92, P hemangioma. Furthermore, it is also proposed that the supplement of copper and Chinese herbal medicines may prevent the incidence of recurrence. Laser was used for the treatment of hemangioma in our country during the 1980s. In foreign literature, there were several reports using Nd:YAG and copper vapor laser for the treatment of agniomasimplex and nevus flammeus. Ar+ laser agglomeration was commonly used for the treatment of angioma conjunctive in our country, but the use of CO2 laser for the treatment of angioma epiderma is not well documented. We wish to report the use of CO2 laser supplemented with He-Ne laser for the treatment of hemangioma in our hospital from April 1988 to December 1989.

    Groundwater recovery and treatment (pump and treat systems) continue to be the most commonly selected remedial technology for groundwater restoration and protection programs at hazardous waste sites and RCRA facilities nationwide. Implementing a typical groundwater recovery and treatment system includes the initial assessment of groundwater quality, characterizing aquifer hydrodynamics, recovery system design, system installation, testing, permitting, and operation and maintenance. This paper focuses on methods used to assess the long-term efficiency of a pump and treat system. Regulatory agencies and industry alike are sensitive to the need for accurate assessment of the performance and success of groundwater recovery systems for contaminant plume abatement and aquifer restoration. Several assessment methods are available to measure the long-term performance of a groundwater recovery system. This paper presents six assessment techniques: degree of compliance with regulatory agency agreement (Consent Order of Record of Decision), hydraulic demonstration of system performance, contaminant mass recovery calculation, system design and performance comparison, statistical evaluation of groundwater quality and preferably, integration of the assessment methods. Applying specific recovery system assessment methods depends upon the type, amount, and quality of data available. Use of an integrated approach is encouraged to evaluate the success of a groundwater recovery and treatment system. The methods presented in this paper are for engineers and corporate management to use when discussing the effectiveness of groundwater remediation systems with their environmental consultant. In addition, an independent (third party) system evaluation is recommended to be sure that a recovery system operates efficiently and with minimum expense.

  12. Monitoring Therapeutic Treatments against Burkholderia Infections Using Imaging Techniques

    Full Text Available Burkholderia mallei, the etiologic agent of glanders, are Category B select agents with biothreat potential, and yet effective therapeutic treatments are lacking. In this study, we showed that CpG administration increased survival, demonstrating protection in the murine glanders model. Bacterial recovery from infected lungs, liver and spleen was significantly reduced in CpG-treated animals as compared with non-treated mice. Reciprocally, lungs of CpG-treated infected animals were infiltrated with higher levels of neutrophils and inflammatory monocytes, as compared to control animals. Employing the B. mallei bioluminescent strain CSM001 and the Neutrophil-Specific Fluorescent Imaging Agent, bacterial dissemination and neutrophil trafficking were monitored in real-time using multimodal in vivo whole body imaging techniques. CpG-treatment increased recruitment of neutrophils to the lungs and reduced bioluminescent bacteria, correlating with decreased bacterial burden and increased protection against acute murine glanders. Our results indicate that protection of CpG-treated animals was associated with recruitment of neutrophils prior to infection and demonstrated, for the first time, simultaneous real time in vivo imaging of neutrophils and bacteria. This study provides experimental evidence supporting the importance of incorporating optimized in vivo imaging methods to monitor disease progression and to evaluate the efficacy of therapeutic treatment during bacterial infections.

    Endoscopic dextranomer/hyaluronic acid (Dx/HA) injection by subureteric transurethral injection (STING) or hydrodistention implantation technique (HIT) for treatment of vesicoureteral reflux (VUR) has variable results with HIT reporting better outcomes. We determined outcomes with each technique comparing reflux resolution rates and evaluating predictors of treatment success and failure. Univariate and multivariate analysis compared 163 patients (246 ureters) who underwent a single endoscopic Dx/HA injection from December 2001 to April 2010. Data on pre, peri, and post-operative variables were prospectively collected. Resolution was defined as no reflux on voiding cystourethrogram (VCUG) at 3 month follow up. Calculated ellipsoid volume (CEV) of Dx/HA mounds was defined as (4/3π(height/2) × (length/2) × (width/2)) based on post-operative ultrasound dimensions. Ureter resolution was 79.75% and 80.84% for STING and HIT, respectively (p = 0.86). Patient resolution was 70.0% and 74.3% for STING and HIT, respectively (p = 0.57). Multivariate ureter analysis revealed lower pre-operative grade (p = 0.004) and injected Dx/HA volume 0.80-1.00 mL (p = 0.039) as predictors of success. CEV <0.20 mL (p = 0.002) and CEV/injected-volume <25% (p = 0.006) were predictors of failure. Volcano morphology (p = 0.004) and lower pre-op grade (p = 0.015) were predictors of success for STING and HIT, respectively. We found no differences in ureter or patient resolution between endoscopic Dx/HA injection techniques STING or HIT. Lower pre-operative grade and moderated Dx/HA volume were predictors of success regardless of technique. Copyright © 2013 Journal of Pediatric Urology Company. Published by Elsevier Ltd.

    Full Text Available Mulberry foliages have high nutritive value (protein content, digestibility and degradability, therefore it is potential to be used as a supplement to poor quality roughages. The objective of this experiment was to evaluate the effect of addition of fermentable energy in the mixed of mulberry and rice straw basal diet. A control diet consisted of either rice straw (RS or urea treated rice straw mixed with mulberry foliage (URS with ratio of 60 : 40%. Treatment was formulated by supplementation of control diet with molasses (as sources of fermentable energy at 3 levels (5, 10 and 15%. The study was conducted in a 2 x 4 factorial experiment, consisted of 2 levels rice straw (untreated and urea treated and 4 levels molasses supplementation (control and 3 levels for molasses. Diets were evaluated using in vitro gas production. The fermentation kinetics was determined from the incubation of 200 mg sample during 96 hours. The calculation of the kinetics based on exponential equation P = A+ B (1-e-ct. A shorter gas production test was carried out to determine truly degradable fermented substrates (in vitro true organic matter degradability/IVTOMD by incubating 500 mg of samples 24 hours. The result showed that there was no significant interaction between rice straw treatment and molasses supplementation on fermentation characteristics, in vitro true dry matter digestibility, fermented substrate and total volatile fatty acid (VFA production. However there was a significant interaction between rice straw treatment on partitioning factor (PF, gas produced, propionic acid production and ratio between acetic acid and propionic acid. Molasses supplementation significantly (P<0.05 decreased gas production and ratio of acetic to propionic acid, and increase PF, propionic acid production in untreated rice straw mulberry (RSM basal diet. It is concluded that molasses supplementation to RSM diet decreased gas production and ratio of C2/C3, and increased PF and

    Full Text Available Background: The surgery for idiopathic congenital vertical talus (CVT can lead to stiffness, wound complications and under or over correction. There are sporadic literature on costing with mixed results. We describe our early experience of reverse ponseti technique. Materials and methods: Four cases (four feet of idiopathic congenital vertical talus (CVT which presented one month after birth were treated by serial manipulation and casting, tendoachilles tenotomy and percutaneous pinning of talonavicular joint. An average of 5.2 (range - four to six plaster cast applications were required to correct the forefoot deformity. Once the talus and navicular were aligned based on the radiographic talus-first metatarsal axis, percutaneous fixation of the talo-navicular joint with a Kirschner wire, and percutaneous tendoachilles tenotomy under anesthesia was performed following which a cast was applied with the foot in slight dorsiflexion. Results: The mean follow-up period for the four cases was 8.5 months (6-12 months. At the end of the treatment all feet were supple and plantigrade but still using ankle foot orthosis (AFO. The mean talocalcaneal angle was 70 degrees before treatment and this reduced to 31 degrees after casting. The mean talar axis first metatasal base angle (TAMBA angle was 60° before casting and this improved to 10.5°. Conclusion: Although our follow-up period is small, we would recommend early casting for idiopathic CVT along the same lines as the Ponseti technique for clubfoot except that the forces applied are in reverse direction. This early casting method can prevent extensive surgery in the future, however, a close vigil is required to detect any early relapse.

    Breast planning with volumetric modulated arc therapy (VMAT) has been explored, especially for left-sided breast treatments, with the primary intent of lowering the heart dose and improving target dose homogeneity. As a trade-off, larger healthy tissue volumes would receive low dose levels, with the potential risk of increasing late toxicities and secondary cancer induction, although no clinical data are available today to confirm the risk level. The scope of this work is to explore the dosimetric trade-offs using two different VMAT plans. Two planning strategies for dual-partial-arc VMAT, RA_avoid and RA_full, with and without avoidance sectors, were explored in a cohort of 20 patients, for whole left breast irradiation for 40.05 Gy to the mean target dose in 15 fractions. Common dose objectives included a stringent dose homogeneity, mean dose to the heart <5 Gy, ipsilateral lung (Ilung) <8 Gy, contralateral lung (Clung) <2 Gy and contralateral breast (Cbreast) <3 Gy. RA_full showed a better dose conformity, lower high-dose spillage in the healthy tissue and lower skin dose. RA_avoid presented a reduction of the mean doses for all critical structures: 51% to the heart, 12% to the Ilung, 81% to the Clung and 73% to the Cbreast. All differences were significant with p < 0.0001. The adaptation of VMAT options to planning objectives reduced significantly the healthy tissue dose levels at the price of some high-dose spillage. Evaluation of the trade-offs for application to the different critical structures should drive in improving the usage of the VMAT technique for breast cancer treatment. Advances in knowledge: Different planning strategies in the same VMAT technique could give significant variations in dose distributions. The choice of the trade-offs would affect the possible future late toxicity and secondary cancer induction risk.

    The study was aimed to evaluate the effects of levothyroxine (LT4) supplemental replacement treatment for pregnancy and analyze the associations between the clinical classification of hypothyroidism and reduced thyroid-stimulating hormone (TSH) in LT4 therapy. Totally, 195 pregnant women with hypothyroidism receiving routine prenatal care were enrolled. They were categorized into three groups: overt hypothyroidism (OH), subclinical hypothyroidism (SCH) with negative thyroperoxidase antibody (TPOAb), and SCH with positive TPOAb. The association between the clinical classification and reduced TSH in LT4 supplemental replacement treatment was assessed. The results indicated that reduced TSH was significantly different among the groups according to the clinical classifications (p = 0.043). The result was also significantly different between patients with OH and patients with SCH and negative TPOAb (p = 0.036). Similar result was reported for the comparison between patients with OH and patients with SCH and positive TPOAb (p = 0.016). Multiple variable analyses showed that LT4 supplementation, gestational age and the variable of clinical classifications were associated with reduced TSH independently. Our data suggested that the therapeutic effect of substitutive treatment with LT4 was significantly associated with different clinical classifications of hypothyroidism in pregnancy and the treatment should begin as soon as possible after diagnosis.

    This paper introduces an optimized evaporation technique for leachate treatment. For this purpose and in order to study the feasibility and measure the effectiveness of the forced evaporation, three cuboidal steel tubs were designed and implemented. The first control-tub was installed at the ground level to monitor natural evaporation. Similarly, the second and the third tub, models under investigation, were installed respectively at the ground level (equipped-tub 1) and out of the ground level (equipped-tub 2), and provided with special equipment to accelerate the evaporation process. The obtained results showed that the evaporation rate at the equipped-tubs was much accelerated with respect to the control-tub. It was accelerated five times in the winter period, where the evaporation rate was increased from a value of 0.37 mm/day to reach a value of 1.50 mm/day. In the summer period, the evaporation rate was accelerated more than three times and it increased from a value of 3.06 mm/day to reach a value of 10.25 mm/day. Overall, the optimized evaporation technique can be applied effectively either under electric or solar energy supply, and will accelerate the evaporation rate from three to five times whatever the season temperature.

    Full Text Available Purpose: To report a case of a cyclodialysis cleft that was successfully managed with gas endotamponade and cyclocryotherapy. Methods: A 37-year-old male victim of a severe blunt ocular trauma was referred to our service for evaluation and treatment of a left eye hypotony. Clinical examination revealed an intraocular pressure of 2 mm Hg, a cyclodialysis cleft extending from the 11 to 1 o'clock positions and a hypotonic maculopathy. Left eye best corrected visual acuity (BCVA was 3/10. The patient failed to respond to conservative treatment with atropine 1%, so a single bubble of 16% C2F6 was injected into the vitreous cavity, followed by superior quadrant transconjunctival cyclocryotherapy. Results: After gas absorption, the intraocular pressure increased to 11 mm Hg and became steady during the 24 months of follow-up. His hypotonic maculopathy resolved, and the BCVA improved to 9/10. Complete closure of the cyclodialysis cleft was documented with ultrasound biomicroscopy. Conclusion: Cryotherapy associated with gas endotamponade is a minimally invasive technique that could be considered for patients with cyclodialysis clefts that fail to respond to medical therapy.

  1. Economics of wastewater treatment in GTL plant using spray technique

    Full Text Available In a Gas-to-liquid (GTL plant, significant quantities of CO2 and reaction water are produced and various chemicals are used as intermediate treatment chemicals. The reaction water is contaminated by these chemicals which impair the pH and the related properties of the water. The pH has to be controlled in the effluent treatment unit before the water is re-used or released to the environment. The overall aim of this investigation is to create a novel technique to address the problem of waste water treatment in GTL plants which will assist in the reduction of greenhouse gas (CO2 emissions into the atmosphere. A laboratory-scale effluent neutralisation unit for pH control utilising gas injectors was designed and built. The unit used the CO2 produced as a by-product of GTL process as wastewater treatment chemical instead of the conventional Sulphuric acid. The quality of wastewater after treatment with CO2 met the standards set by the state regulatory agency. The economics of the new process shows a better payout period of 3.6 years for capital investment of $1,645 Million compared to 4.7 years for an existing plant layout with capital investment of $1,900 Million. The effects of increase in plant capacity showed a lower payback back of 2.8 years for plant capacity of 140,000 barrels/day (22258 m3/day, 3.6 years for 34,000 barrels/day and 6.0 years for 12,500 barrels/day (1987 m3/day plant capacity. The sensitivity analysis using crystal ball simulator with ‘Microsoft Excel’ shows that the annual revenue has the greatest effects on the NPV of the plant than the CAPEX and inflation rate. Apart from the environmental benefits the process generates by reducing CO2 emissions into the atmosphere, the study also concludes that the replacement of conventional Sulphuric acid (H2SO4 unit with CO2 improves the economics of the plant.

The unit used the CO2 produced as a by-product of GTL process as wastewater treatment chemical instead of the conventional Sulphuric acid. The quality of wastewater after treatment with CO2 met the standards set by the state regulatory agency. The economics of the new process shows a better payout period of 3.6 years for capital investment of $1,645 Million compared to 4.7 years for an existing plant layout with capital investment of $1,900 Million. The effects of increase in plant capacity showed a lower payback back of 2.8 years for plant capacity of 140,000 barrels/day (22258 m3/day), 3.6 years for 34,000 barrels/day and 6.0 years for 12,500 barrels/day (1987 m3/day) plant capacity. The sensitivity analysis using crystal ball simulator with 'Microsoft Excel' shows that the annual revenue has the greatest effects on the NPV of the plant than the CAPEX and inflation rate. Apart from the environmental benefits the process generates by reducing CO2 emissions into the atmosphere, the study also concludes that the replacement of conventional Sulphuric acid (H2SO4) unit with CO2 improves the economics of the plant.

    The main objective of SeRTech project (Sediment Remediation Technologies) is to develop an integrated cost-effective treatment system to address heterogeneous contamination and matrixes, such as those of Venice lagoon dredged materials. Seven treatment techniques, selected over a large array, have been tested: Thermal Desorption. A preliminary set of isothermal treatments at different temperatures was performed to evaluated the losses of organic and the most volatile metals (such as Pb and As). An almost full volatilisation of organic compounds was observed at temperatures ranging between 200 and 300 C. Chemical stabilization-solidification. Depuracque Impianti srl process uses innovative patented additives (polimers and superplasticizers) to immobilize heavy metals into cement pellets. Solvent extraction. Organic contaminants such as PAHs and PCBs were extracted from sediments by using ethyl acetate. The results showed that solvent extraction obtained high efficiency in removal of PAHs and other organic contaminants. Immobilization of heavy metals employing sulfate-reducing bacteria. High Gradient Magnetic Separation (HGMS). Sulfate reducing bacteria (SBR) produce an iron sulfide containing biomass with a high capability to adsorbe hevy metals and some organic compounds. This biomass can be separated through a high gradient magnetic field removing a substantial fraction of contaminants. Vitrification. Sediment was mixed with other inorganic wastes (glass cullet, feldsphatic tailings) and low amounts of row material to obtain an inert glass, which in turn can be recycled into other useful products, for example glass fibres, foam glass and glass ceramics. Phytoremediation. Phragmites australis (Cav.), Trin; Juncus Iacustrus, Arthrocnmemum fruticosum, Spartina maritima, Helianthus annuus L., Zea mais L., Brassica napus L., Brassica juncea L. have been selected to verify limit and efficiency of phytoextraction for heavy metals (Zn, Pb, Hg, Cd, As, Ni).

    Individualized, nutritional support reduced undernutrition among older stroke patients and improved quality of life in our recent randomized, controlled trial. Weight control thus seems to be important after stroke, and methods for monitoring nutritional status need to be simple and non-invasive. Here we aimed to assess if the nutritional intervention altered body composition in men and women in this study cohort, and also to examine the correlation between the methods for assessing body-, fat- and fat-free mass. Acute stroke patients > 65 years at nutritional risk were randomized to either individualized, nutritional treatment with energy- and protein rich supplementation (intervention, n = 58) or routine, nutritional care (control, n = 66) while in hospital. Body composition was assessed with anthropometry and bioelectrical impedance. The follow-up period was three months. During the first week while in hospital, weight loss was smaller in the intervention group compared with the controls (P = 0.013). After three months weight- and fat loss were significant in both men and women. Whereas no significant differences were found in changes in body composition between the male study groups, in the women both weight loss (P = 0.022) and fat loss (P = 0.005) was smaller in the intervention group compared with the controls. A high correlation (r = 0.87) between mid upper arm circumference (MUAC) and body mass index (BMI) was found. Individualized nutritional support to older stroke patients in hospital was beneficial for maintaining an adequate body mass and body composition the first week and seemed to have a preventive effect on fat loss among women, but not among men after three months. Measurement of MUAC may be used in the assessment of nutritional status when BMI cannot be obtained. This trial is registered with ClinicalTrials.gov, number NCT00163007.

    Full Text Available INTRODUCTION: The MAINTAIN study is an on-going RCT comparing high-dose micronutrient and anti-oxidant supplementation versus recommended daily allowance (RDA vitamins in slowing HIV immune deficiency progression in ART-naïve people with HIV infection. OBJECTIVE: We planned analysis of the first 127 participants to determine the baseline prevalence of serum micronutrient deficiencies and correlates, as well as tolerance and adherence to study interventions. METHODS: Participants receive eight capsules twice daily of 1 high-dose or 2 RDA supplements for two years and are followed-up quarterly for measures of immune deficiency progression, safety and tolerability. Regression analysis was used to identify correlates of micronutrient levels at baseline. Adherence was measured by residual pill count, self-report using the General Treatment Scale (GTS and short-term recall HIV Adherence Treatment Scale (HATS. RESULTS: Prior micronutrient supplementation (within 30 days was 27% at screening and 10% of study population, and was not correlated with baseline micronutrient levels. Low levels were frequent for carotene (24%80% in 75% of participants. CONCLUSION: Micronutrient levels in asymptomatic HIV+ persons are in keeping with population norms, but micronutrient deficiencies are frequent. Adherence levels are high, and will permit a valid evaluation of treatment effects. TRIAL REGISTRATION: ClinicalTrials.gov NCT00798772.

  6. Hepatitis C infected patients need vitamin D3 supplementation in the era of direct acting antivirals treatment

    It has been reported that the serum level of vitamin D3 (VitD3) could affect the natural course of chronic hepatitis C (CH-C) and the response to treatment with pegylated interferon (Peg-IFN) and ribavirin. Although several mechanisms for the favorable effects of VitD3 supplementation were reported, the total effect of VitD3 supplementation remains unclear. Previously, we reported that supplementation with 1(OH)VitD3 could enhance the Th1 response inducing not only a favorable immune response for viral eradication but also HCC control. Recently, the main treatment of CH-C should be direct acting antivirals (DAAs) without Peg-IFN. Peg-IFN is a strong immune-modulator. Therefore, an immunological analysis should be carried out to understand the effect of VitD3 after treatment of DAAs without Peg-IFN. The induction of a favorable immune response by adding VitD3 might be able to suppress the hepatocarcinogenesis after achieving SVR, especially in children and elderly patients with severe fibrosis lacking sufficient amounts of VitD3.

    This study was carried out for the development of pilot plant which can produce industrial water from effluent of sewage treatment plant by irradiation. As a basic study, the characteristics on decomposition of organic compounds, decoloration and sterilization of bacteria were evaluated. An additive mainly composed by sponge type of TiO{sub 2} was developed for reduction of irradiation dose and enhancement of removal efficiency of organic compounds. The optimum pilot plant was composed of sysem with gamma irradiation/ozone/additive/ion exchange. The effluent with BOD 20 ppm, COD 25 ppm and color 25 ADMI could be treated to less than 5 ppm and 5 ADMI under the irradiation of 5 kGy. The disinfection of microorganism also could be done perfectively under the same irradiation. A small amount of heavy metal ions and inorganic ions, nitrogen, contained in effluent were removed by ion exchanger. From the operation of pilot plant it could be concluded that irradiation technique can be a good method for the produce of industrial water from effluent.

    The average wind speed in Murdochville, Quebec is 9 m/s, making it one of Canada's richest wind resource regions. As such, it is the site of a natural laboratory for the CORUS Center to study the North American climate and wind energy extraction. This presentation outlined research initiatives at CORUS, with particular reference to innovative treatments against ice accretion on wind turbine blades. Ice changes the aerodynamic profile of turbine blades, overloads the structure, increases vibrations and causes component wear. This results in loss of energy production, frequent failures, reduced service life and increased operating and maintenance costs. CORUS has been working on reducing ice accretion on blade surfaces without affecting the manufacturing process using ion implantation and UV rays irradiation. The ions used in the process are hydrogen, fluorine and argon. The technique modifies the surface chemical properties at the nano-scale depth level. This presentation provided details of the ion implantation procedure and the UV rays exposure procedure. An evaluation of wetting and water contact angles on blade samples was provided. Preliminary results showed that the high hysteresis of the non-treated samples had favourable conditions to ice adhesion. Argon implantation reduced the water contact angles and particularly hysteresis. Hydrogen implantation slightly increased the water contact angles and reduced the hysteresis. The process was beneficial in terms of service life. UV irradiation increased the hysteresis. figs.

    Conventional treatment of osteoarthritis (OA) with non-steroidal anti-inflammatory drugs is associated with serious gastrointestinal side effects and in view of the recent withdrawal of some cyclo-oxygenase-2 inhibitors, identifying safer alternative treatment options is needed. The objective of this systematic review is to evaluate the existing evidence from randomised controlled trials of two chemically related nutritional supplements, dimethyl sulfoxide (DMSO) and methylsulfonylmethane (MSM) in the treatment of OA to determine their efficacy and safety profile. The electronic databases [Cochrane Library, Medline, Embase, Amed, Cinahl and NeLH (1950 to November 2007)] were searched. The search strategy combined terms: osteoarthritis, degenerative joint disorder, dimethyl sulfoxide, DMSO, methylsulfonylmethane, MSM, clinical trial; double-blind, single blind, RCT, placebo, randomized, comparative study, evaluation study, control. Inclusion and exclusion criteria were applied. Data were extracted and quality was assessed using the JADAD scale. Six studies were included [evaluating a total of 681 patients with OA of the knee for DMSO (N=297 on active treatment); 168 patients for MSM (N=52 on active treatment)]. Two of the four DMSO trials, and both MSM trials reported significant improvement in pain outcomes in the treatment group compared to comparator treatments, however, methodological issues and concerns over optimal dosage and treatment period, were highlighted. No definitive conclusion can currently be drawn for either supplement. The findings from all the DMSO studies need to be viewed with caution because of poor methodology including; possible unblinding, and questionable treatment duration and dose. The data from the more rigorous MSM trials provide positive but not definitive evidence that MSM is superior to placebo in the treatment of mild to moderate OA of the knee. Further studies are now required to identify both the optimum dosage and longer

    Full Text Available Background and Aims. This study examined if exercise and omega-3 fatty acid (n3PUFA supplementation is an effective treatment for hepatic steatosis in obese, hyperphagic Otsuka Long-Evans Tokushima Fatty (OLETF rats. Methods. Male OLETF rats were divided into 4 groups (n=8/group: (1 remained sedentary (SED, (2 access to running wheels; (EX (3 a diet supplemented with 3% of energy from fish oil (n3PUFA-SED; and (4 n3PUFA supplementation plus EX (n3PUFA+EX. The 8 week treatments began at 13 weeks, when hepatic steatosis is present in OLETF-SED rats. Results. EX alone lowered hepatic triglyceride (TAG while, in contrast, n3PUFAs failed to lower hepatic TAG and blunted the ability of EX to decrease hepatic TAG levels in n3PUFAs+EX. Insulin sensitivity was improved in EX animals, to a lesser extent in n3PUFA+EX rats, and did not differ between n3PUFA-SED and SED rats. Only the EX group displayed higher complete hepatic fatty acid oxidation (FAO to CO2 and carnitine palmitoyl transferase-1 activity. EX also lowered hepatic fatty acid synthase protein while both EX and n3PUFA+EX decreased stearoyl CoA desaturase-1 protein. Conclusions. Exercise lowers hepatic steatosis through increased complete hepatic FAO, insulin sensitivity, and reduced expression of de novo fatty acid synthesis proteins while n3PUFAs had no effect.

    Full Text Available The first laparoscopic cholecystectomy (LC was performed in France in 1987 by a French surgeon (P. Mouret, and it rapidly became accepted until the end of the nineties in Europe and America as a "gold standard" in the treatment of the gallbladder. "There are just a few examples in the history of surgery, where the advantage of some surgical techniques is so quickly imposed, as it is in the case of laparoscopic cholecystectomy" (Cusshieri. Assuming the present of a surgical skill and experience, welltrained team and the specific technical equipment, the main advantages of this surgical method are less operative trauma and postoperative pain, faster recovery and a shorter hospital stay. The percentage of conversion to open cholecystectomy is 2%-20% and it is caused by certain conditions, such as older age, morbid obesity, and expressed inflammation of gallbladder and biliary anatomical anomalies. Male gender, anatomical variations, previous abdominal operations and technical problems, were rarer causes of conversion. Non-compliance and non-recognition of these risk factors can lead to complications, most notably the common bile duct injuries. At the Surgical Clinic in Nis, in the period of 3 years (January 2010 to November 2013 1.389 patients with symptomatic cholelithiasis underwent surgery, 626 (45,1% using standard techniques of laparoscopic method. Most patients, 60,10%, were female and 39,90% were male. Chronic calculous cholecystitis was an indication of the 86,20%, 8,50% in the acute, gallbladder polyp 5,30%. Conversion was forced out in 28 patients (4.47%. There have been no lethal operative outcomes in observed period, intraoperative lesions of vascular structures were not notified, total specific morbidity was about 2,07%. The technical aspect is still dominant at laparoscopic cholecystectomy (LC. Outstanding results at our clinic and in the world, impose the need for further development of this method, education of surgeons and staff

    2014-01-01

    Full Text Available The most effective treatment of the potential food supplement corn distillers’ grains with solubles using a fungal phytase to degrade phytic acid and release phosphorus was explored. Compared to the untreated grains with solubles, the phytic acid level in the grains with solubles was reduced by phytase treatment but treatment with 4 units of enzyme/g was more effective than 2 units of enzyme/g after 2 h. At 30°C or 45°C, 4 units of phytase/g reduced the phytic acid content of the grains with solubles by at least 94% after 2 h. The available phosphate in the grains treated for 2 h with 4 units of enzyme/g was increased by at least 1.5-fold compared to the untreated grains. Although phytic acid levels in the grains with solubles was reduced at 28°C, 30°C, 37°C, 40°C, or 45°C using 4 units of phytase/g for 2 h, the greatest reduction (96% in phytic acid concentration occurred at 40°C. The available phosphate in the phytase-treated grains at 40°C was increased after 2 h by 1.9-fold compared to the control grains. Overall, phytase treatment of this potential food supplement improved it by increasing its phosphate content while reducing its phytic acid content.

    An important aspect of nursing theory development has been the adaptation of theory from other disciplines within the metaparadigm of nursing. This eclectic approach to theory development enhances the broad humanistic theory base on which effective, professional nursing practice is based. The aim of this article is to describe the process of integrating two distinct psychotherapeutic approaches into one coherent mental health nursing intervention for the treatment of affective symptoms in older adults. Guidelines for using this integration process in psychiatric mental health nursing clinical practice are presented and illustrated through the case study approach. A case study is presented describing a clinical situation in which life review techniques were used to enhance the outcomes of a cognitive therapy experience for older adults enrolled in outpatient psychotherapy treatment for acute adjustment disorder with an affective component. The advanced practice psychiatric mental health nurse who approaches psychotherapeutic interventions with older adult clients from an eclectic approach can achieve successful outcomes by having a clear understanding of (i) the dynamics of the various psychotherapeutic approaches, (i) the skill level of the practitioner, (iii) the psychosocial sophistication of the client, and (iv) the pathology being treated. In addition, active involvement by the client in a treatment process that matches his/her psychosocial skill and coping resource level will contribute to effective resolution of pathology. A cognitive therapy approach supplemented by life review techniques is an excellent example of an effective, eclectic treatment approach of affective disorders in older adults.

    Prostate cancer (PCa), the most commonly diagnosed cancer and second leading cause of male cancer death in Western societies, is typically androgen-dependent, a characteristic that underlies the rationale of androgen deprivation therapy (ADT). Approximately 90% of patients initially respond to ADT strategies, however many experience side effects including hot flashes, cardiotoxicity, metabolic and musculoskeletal alterations. This review summarizes pre-clinical and clinical studies investigating the ability of dietary supplements to alleviate adverse effects arising from ADT. In particular, we focus on herbal compounds, phytoestrogens, selenium (Se), fatty acids (FA), calcium, and Vitamins D and E. Indeed, there is some evidence that calcium and Vitamin D can prevent the development of osteoporosis during ADT. On the other hand, caution should be taken with the antioxidants Se and Vitamin E until the basis underlying their respective association with type 2 diabetes mellitus and PCa tumor development has been clarified. However, many other promising supplements have not yet been subjected large-scale clinical trials making it difficult to assess their efficacy. Given the demographic trend of increased PCa diagnoses and dependence on ADT as a major therapeutic strategy, further studies are required to objectively evaluate these supplements as adjuvant for PCa patients receiving ADT.

    It was suggested that ascorbic acid as a natural chelating agent can influence lead toxicokinetics and improve chelating properties of dimercaptosuccinic acid (DMSA) in adult rats. In this paper potential benefits of ascorbic acid supplementation, alone or combined with DMSA, in decreasing lead retention in suckling rats were evaluated. Such data in young mammals are not available. L-Ascorbic acid (daily dose 650 mg/kg b.wt.) and/or DMSA (daily dose 91 mg/kg b.wt.) were administered orally to suckling Wistar rats either during ongoing 8-day oral lead exposure (as acetate; daily dose 2 mg lead/kg b.wt.) or after 3-day lead exposure (total dose 12 mg lead/kg b.wt.). Lead concentrations were analysed in the carcass (skeleton), liver, kidneys and brain by atomic absorption spectrometry. By ascorbic acid supplementation lead retention was not reduced under either lead exposure condition. Lead concentration was even increased in the carcass. Treatment with DMSA under both exposure conditions significantly reduced lead in all analysed tissues. Combined treatment with ascorbic acid and DMSA during ongoing lead exposure was substantially less effective than DMSA treatment alone, and did not affect DMSA efficacy when administered after lead exposure. It was concluded that ascorbic acid administered either during or after lead exposure in suckling rats has no beneficial effect on either lead retention or DMSA chelation effectiveness.

    Full Text Available Abstract This is a case report of adrenomyeloneuropathy (AMN, the adult variant of adrenoleukodystryphy (ALD. The diagnoses in the patient, aged 34, was confirmed via increased serum very long chain fatty acid concentration (VLCFA. Treatment started with the cholesterol lowering drug, atorvastatin, followed by add-on therapy with Lorenzo's oil (LO and finally supplementation with docosahexaenoic acid (DHA. The magnetic resonance imaging (MRI scan of the AMN patient before DHA treatment, already showed abnormal white matter in the brain. Although the MRI showed no neurological improvement after 6 months of DHA treatment, no selective progression of demyelination was detected in the AMN patient. Contrary to what was expected, LO failed to sustain or normalize the VLCFA levels or improve clinical symptoms. It was however, shown that DHA supplementation in addition to LO, increased DHA levels in both plasma and red blood cells (RBC. Additionally, the study showed evidence that the elongase activity in the elongation of eicosapentaenoic acid (EPA to docosapentaenoic acid (DPA might have been significantly compromised, due to the increased DHA levels.

    Abstract Hepatitis C virus (HCV) infection and type 2 diabetes mellitus (T2DM) present a significant health burden, with increasing complications and mortality rates worldwide. Pycnogenol® (PYC), a natural product, possesses antidiabetic and antiviral properties that may improve HCV-associated T2DM. In this review, we present previously published data on the effectiveness of PYC against HCV replication and T2DM. We believe that supplementing conventional treatment with PYC may improve the current HCV therapy, attenuate HCV-associated T2DM, and reduce the risk of complications such as cirrhosis or hepatocellular carcinoma and cardiovascular disease.

    Full Text Available Background/Aim. Tumescent local anesthesia (TLA is a technique for local and regional anesthesia of the skin and the subcutaneous tissue, using infiltration of large amounts of a diluted solution of local anesthetic. This technique is applied in plastic surgery, liposuction as well as in dermatology for the entire series of dermatocosmetic procedures. The purpose of this study was to determine efficiency of surgical treatment of varicose vein using TLA as an alternative method to a conventional treatment for varicose vein. Methods. Seventy-two patients with varicose vein were enrolled in the study. All of them were operated on applying TLA, from April 2008 to November 2009. TLA solution consisted of local anesthetics was used. TLA solutions used were: 1% prilocaine-chloride with adrenaline supplement, and 2% lidocaine-chloride and adrenaline in concentration of 0.1%-0.4%. Results. Out of 72 patients, we stripped great saphenous vein from 60 patient and did varicectomy as well as ligation of insufficiently perforating veins. In 12 patients we did partial varicectomy and ligation of perforating veins. There were not any patients with the need for continued surgery, as well as bringing patient to the general anesthesia due to pain during the surgery. One patient came for postoperative opening wound in the groin, one for infection of the wound and one for the formation of seroma in the groin. There were not any allergic reactions or systemic complications in the operations as well as postoperative period. Postoperatively, all the patients were treated with compressive elastic bandage during the period of 6 weeks as well as anticoagulation prophylaxis in the duration of 5 days. Conclusion. Surgery of varicose veins with implementation of TLA is easy and safe method with very low percentage of complications and unwanted effects. It is a good alternative method to classic surgery of varicose veins. The economic aspect is a very important component

    Dentists are often faced with extensively resorbed mandibular ridges with shallow buccal vestibule and high insertion of the mentalis muscle in relation to the crest of the ridge, causing the displacement of the prosthesis. Vestibuloplasty techniques aim at eliminating the muscle insertions, reposition the mucosa, and increase the area chapeável, giving more stability to the prosthesis. Among the techniques to deepen the vestibule are submucosal vestibuloplasties by secondary epithelialization and with mucosal and skin grafts. We will discuss vestibuloplasty by secondary epithelialization with emphasis on the so-called modified Kazanjian technique. This technique provides an appropriate result and does not require hospitalization, additional surgery at the donor, or prolonged periods without the use of prosthesis.

    Surgical excision has been the accepted treatment of laryngeal polypoid degeneration, or chronic polypoid corditis. We report on 29 women with polypoid degeneration who received one of three surgical treatments: vocal fold stripping, carbon dioxide laser obliteration, or the Hirano technique. The duration of postoperative dysphonia was longest with the laser removal and shortest with the Hirano technique. A combination of vocal hygiene management and the Hirano technique of removal provided the most efficacious treatment.

    Full Text Available Evidence supporting the impact of therapeutic zinc supplementation on the duration and severity of diarrhea among children under five is largely derived from studies conducted in South Asia. China experiences a substantial portion of the global burden of diarrhea, but the impact of zinc treatment among children under five has not been well documented by previously published systematic reviews on the topic. We therefore conducted a systematic literature review, which included an exhaustive search of the Chinese literature, in an effort to update previously published estimates of the effect of therapeutic zinc. We conducted systematic literature searches in various databases, including the China National Knowledge Infrastructure (CNKI, and abstracted relevant data from studies meeting our inclusion and exclusion criteria. We used STATA 12.0 to pool select outcomes and to generate estimates of percentage difference and relative risk comparing outcomes between zinc and control groups. We identified 89 Chinese and 15 non-Chinese studies for the review, including studies in 10 countries from all WHO geographic regions, and analyzed a total of 18,822 diarrhea cases (9469 zinc and 9353 control. None of the included Chinese studies had previously been included in published pooled effect estimates. Chinese and non-Chinese studies reported the effect of therapeutic zinc supplementation on decreased episode duration, stool output, stool frequency, hospitalization duration and proportion of episodes lasting beyond three and seven days. Pooling Chinese and non-Chinese studies yielded an overall 26% (95% CI: 20%−32% reduction in the estimated relative risk of diarrhea lasting beyond three days among zinc-treated children. Studies conducted in and outside China report reductions in morbidity as a result of oral therapeutic zinc supplementation for acute diarrhea among children under five years of age.

    Interdental clefts or invaginations contribute to orthodontic relapse and poor periodontal health in extraction cases. These clefts or invaginations can be removed both by electrosurgical or conventional surgical gingivectomy techniques. This study investigates and compares the efficacy of two different techniques to remove gingival clefts with respect to periodontal health and patient tolerance. Twenty-two patients (mean age, 15.7 years) with bilateral gingival clefts participated in this study. In each patient, the gingival invaginations were removed by gingivectomy using electrosurgery on one side and conventional surgery on the contralateral side. The length and depth of the invaginations, the gingival index of the adjacent teeth, and the changes in visual analogue scale scores were recorded before and after the operation for both groups. Mann-Whitney U-test and Wilcoxon tests were used to analyze the data statistically. The results showed significant improvement in invagination depth and length and gingival index scores for both techniques. There were no statistical differences between the two gingivectomy techniques with respect to gingival health and patient tolerance. Both techniques can be used to remove the gingival invaginations efficiently.

    We examined the use of Kratom (Mitragyna sp.), a dietary supplement with mu-opioid agonist activity, by members of a cybercommunity who self-treat chronic pain with opioid analgesics from Internet pharmacies. Within one year, an increase in the number of mentions on Drugbuyers.com, a Web site that facilitates the online purchase of opioid analgesics, suggested that members began managing opioid withdrawal with Kratom. This study demonstrates the rapidity with which information on psychoactive substances disseminates through online communities and suggests that online surveillance may be important to the generation of effective opioid analgesic abuse prevention strategies.

    Undernutrition is common among tuberculosis (TB) patients. The objective of this study was to assess the effect of multi-micronutrient supplementation during TB treatment on weight, body composition, and handgrip strength. A total of 865 patients with smear-positive (PTB+) or -negative (PTB......-) pulmonary TB were randomly allocated to receive a daily biscuit with or without multi-micronutrients for 60 d during the intensive phase of TB treatment. Weight, arm fat area, arm muscle area, and handgrip strength were assessed at baseline and after 2 and 5 mo. At 2 mo, the multi-micronutrient...... supplementation led to a higher handgrip gain (1.22 kg; 95% CI = 0.50, 1.94; P = 0.001) but had no effects on other outcomes. The effects of multi-micronutrient supplementation were modified by HIV infection (P-interaction = 0.002). Among HIV- patients, multi-micronutrient supplementation increased weight gain...

    Full Text Available Dimethyl sulphoxide and methylsulfonylmethane are two related nutritional supplements used for symptomatic relief of osteoarthritis (OA. We conducted a meta-analysis to evaluate their efficacy in reducing pain associated with OA. Randomized or quasi-randomized controlled trials (RCTs, identified by systematic electronic searches, citation tracking and searches of clinical trial registries, assessing these supplements in osteoarthritis of any joint were considered for inclusion. Meta-analysis, based on difference in mean pain related outcomes between treatment and comparator groups, was carried out based on a random effect model. Seven potential trials were identified of which three RCTs, two DMSO and one MSM (total N=326 patients were eligible for inclusion. All three trials were considered high methodological quality. A significant degree of heterogeneity (χ2=6.28, P=.043 was revealed. Two studies demonstrated statistically significant (but not clinically relevant reduction in pain compared with controls; with one showing no group difference. The meta-analysis confirmed a non significant reduction of pain on visual analogue scale of 6.34 mm (SE = 3.49, 95% CI, −0.49, 13.17. The overall effect size of 1.82 was neither statistically nor clinically significant. Current evidence suggests DMSO and MSM are not clinically effective in the reduction of pain in the treatment of OA. No definitive conclusions can currently be drawn from the data due to the mixed findings and the use of inadequate dosing periods.

    Full Text Available A study was carried out to determine the epidemiology of gastrointestinal nematodes in indigenous Tuli cattle and the effect of dietary protein supplementation and anthelmintic treatment on productivity in young growing cattle. Forty steers with an average age of 18 months were divided into 4 groups; 1 fenbendazole (slow release bolus and cottonseed meal (FCSM group, 2 fenbendazole (FBZ group, 3 cottonseed meal (CSM group and 4 control (no cottonseed meal and no fenbendazole (control group. Performance parameters measured included wormeggs per gram of faeces (EPG, packed cell volume (PCV, albumin and live-weight gain. Results showed that faecal worm egg counts were lower and PCV was higher in the FCSM and FBZ groups than in the CSM and control groups (P < 0.01. Weight gains were higher in the CSMand FCSM groups than in the FBZ and control groups (P < 0.05. The cost benefits of anthelmintic treatment and dietary supplementation were apparent in this study. The improved growth performance of the FCSM, FBZ and CSM groups reflected a financial gain over the controls on termination of the study. The dominant genera of gastrointestinal nematodes on faecal culture, pasture larval counts and necropsy were Cooperia and Haemonchus. The incidences of Trichostrongylus, Oesophagostomum and Bunostomum were low.

    Full Text Available Aim: Although pilonidal disease is experienced commonly, there is no definitive algorithm. Our purpose is to contribute in determining treatment algorithm by comparing the conservative phenol treatment (PT method with limberg flap technique (LFT used frequently for pilonidal disease surgery.Material and Method: Patients diagnosed with pilonidal sinus and treated with PT and LFT between February 2011 and September 2014 in Buca Seyfi Demirsoy State Hospital General Surgery service are retrospectively enrolled in the study. Patients are contacted with the help of their files and included in the study. Patients are compared in terms of age, gender, pain-free walking and start date for going back to work, complications, success and relapse ratios. Results: 73 (81.1% of the cases were male, 17 (18.9% were female and their average age was 24±8.4(14-55. No statistically significant difference was detected between patients who have undergone LFT and PT in terms of success and relapse (p>0,05. Hospitalization period was average 1.55±0.9 days for patients who have undergone LFT. FT was applied as outpatient treatment for all patients. A statistically significant difference was determined in favor of PT as a result of comparing postoperative complications, pain-free walking and start date for going back to work (p=0,00. Discussion: In our study, we have proven that LFT, which is a method used frequently with recognized success is not superior to PT in terms of success and relapse ratios (p>0.05. On the contrary, when compared in terms of postoperative complication, pain-free walking time and start date for going back to work, we observed that PT is more advantageous than LFT (p=0,00. We consider that PT can be prefered treatment method due to its acceptable relapse ratio, low postoperative complication ratio, good postoperative patient comfort, capability of performing repeated applications and constant availability of operation option.

    Rates of medial and/or lateral gutter impingement after total ankle replacement are not insignificant. If impingement should occur, it typically arises an average of 17 months after total ankle replacement. Our patient underwent treatment for right ankle medial gutter bony impingement with arthroscopic debridement 5 years after her initial total ankle replacement. Standard anteromedial and anterolateral portals and a 30° 2.7-mm-diameter arthroscope were used. An aggressive soft-tissue and bony resection was performed using a combination of curettes, a 3.5-mm shaver, a 5.5-mm unsheathed burr, a drill, and a radiofrequency ablator. This case shows that arthroscopic treatment is an effective and potentially advantageous alternative to open treatment of impingement after total ankle replacement. In addition, symptoms of impingement often improve in a short amount of time after arthroscopic debridement of the medial and/or lateral gutter.

    This document describes the formulation and operation of a model designed to assist in planning supplementation projects. It also has application in examining a broader array of questions related to natural fish production and stock restoration. The model is referred to as the Ecosystem Diagnosis and Treatment (EDT) Model because of its utility in helping to diagnose and identify possible treatments to be applied to natural production problems for salmonids. It was developed through the Regional Assessment of Supplementation Project (RASP), which was an initiative to help coordinate supplementation planning in the Columbia Basin. The model is operated within the spreadsheet environment of Quattro Pro using a system of customized menus. No experience with spreadsheet macros is required to operate it. As currently configured, the model should only be applied to spring chinook; modifications are required to apply it to fall chinook and other species. The purpose of the model is to enable managers to consider possible outcomes of supplementation under different sets of assumptions about the natural production system and the integration of supplementation fish into that system. It was designed to help assess uncertainty and the relative risks and benefits of alternative supplementation strategies. The model is a tool to facilitate both planning and learning; it is not a predictive model. This document consists of three principal parts. Part I provides a description of the model. Part II is a guide to running the model. Part III provides theoretical documentation. In addition, a sensitivity analysis of many of the model's parameters is provided in the appendix. This analysis was used to test whether the model produces consistent and reasonable results and to assess the relative effects of specific parameter inputs on outcome.

    2015-12-01

    Full Text Available There is limited evidence on adherence to the recommended dose and duration of zinc supplementation for diarrheal episodes in children under five years of age. In selected districts of Uttar Pradesh, India, we sought to assess adherence to the nationally advised zinc treatment regimen (ie, 10 mg/day for ages 2–6 months and 20 mg/day for ages 7–59 months for 14 days among caregivers of zinc–prescribed children. We identified and conducted follow–up visits to children advised zinc for the treatment of diarrhea. At the initial visit, we collected data on the treatment instructions received from providers. Caregivers were asked to record treatments administered on a pictorial tracking form and were asked to retain all packaging for collection at follow–up. We quantified the average dose and duration of zinc therapy and built logistic regression models to assess the factors associated with caregiver adherence to national guidelines. Caregivers administered zinc for an average of 10.7 days (standard deviation (SD = 3.9 days; median = 13 days, and 47.8% continued treatment for the complete 14 days. Among children receiving zinc syrups and tablets respectively, the age appropriate dose was received by 30.8% and 67.3%. Adherence to age appropriate dose and continuation of zinc for 14 days were highly associated with having received appropriate provider instructions. Our results indicate moderate–to–good adherence to national zinc treatment guidelines for diarrhea among caregivers in rural India. Our findings also highlight the importance of provider guidance in ensuring adherence to zinc dose and duration. Programs aiming to scale–up zinc treatment for childhood diarrhea should train providers to successfully communicate dosing instructions to caregivers, while also addressing the tendency of caregivers to terminate treatment once a child appears to have recovered from an acute diarrheal episode.

  7. Surgical treatment of idiopathic syringomyelia: Silastic wedge syringosubarachnoid shunting technique

    Directory of Open Access Journals (Sweden)

    Teck M Soo

    2014-01-01

    Conclusions: Shunting procedures for the syringomyelia disease spectrum have been criticized due to the inconsistent long-term outcomes. This surgical technique used to treat symptomatic idiopathic syringomyelia has been devised based on our intraoperative experience, surgical outcomes, and evaluation of the literature. The purpose of the wedges is to preserve patency of the communication between the syrinx cavity and the expanded subarachnoid space by preventing healing of the myelotomy edges and by maintaining an artificial conduit between the syrinx cavity and the subarachnoid space. Although short-term results are promising, continued long-term follow up is needed to determine the ultimate success of the silastic wedge shunting procedure.

    Poor nutritional status at initiation of antiretroviral therapy (ART) is predictive of mortality. Decreased dietary intake is a major determinant of weight loss in HIV. Despite a biological rationale to treat undernutrition in adults receiving ART, few studies have provided data on feasibility, safety, effectiveness, and sustainability of specific macronutrient supplements with HIV treatment in adults, especially supplements such as a food basket, a supplement approach seldom evaluated in spite of its wide use. We present the rationale and design for a study of a locally procured macronutrient supplement given to HIV-infected patients initiating ART with a body mass index (BMI) ≤20.0 kg/m(2). The objective was to determine feasibility of procurement, distribution, safety and to obtain preliminary effectiveness data for a locally procured supplement. The design was a comparative study for 200 adult participants at two Kenya government-supported clinics. The primary outcome was BMI at 24 weeks. Supplement duration was 24 weeks, total follow-up was 48 weeks, and the study included a comparison site. Novel aspects of this study include use of a standardized macronutrient supplement to protect the participant against household food sharing, and a complementary micronutrient supplement. Comprehensive data collected included dietary intake, HIV-related quality-of-life, food security, neuropsychiatric assessments, laboratory studies, and household geomapping. Assessments were made at baseline, at 24 weeks, and at 48 weeks post-ART initiation. Challenges included establishing a partnership with local millers, distribution from the HIV clinic, food safety, and tracking of participants. These findings will help inform nutrition support programming in Kenya and similar settings, and provide needed data regarding use of macronutrient supplements as an adjunctive intervention with ART.

    This work proposes the use of high performance liquid chromatography coupled to inductively coupled plasma mass spectrometry (HPLC-ICP-MS) for simultaneous speciation of arsenic and chromium in iron supplements used for the treatment of anemia. The sample preparation procedure recommended for the total determination of arsenic and chromium was established using acid digestion in a microwave assisted oven. For speciation analysis, however, the microwave-assisted extraction procedure involved the use of water as extraction solvent at 90°C for 30min. The chromatographic separation was performed using a mobile phase containing 1.0mM tetrabutylammonium hydroxide (TBAH), 0.7mM ethylenediaminetetraacetic acid (EDTA) and 5% methanol at pH 7.2. Helium was used in the collision cell for elimination of the interferences. Under optimized conditions, the separation and detection of the As(III), As(V), Cr(III) and Cr(VI) species can be performed in 5min, permitting their quantification with the external calibration technique with standards prepared in the mobile phase. The limits of quantification obtained were 0.008, 0.010, 0.5 and 0.14µgg(-1), for As(III), As(V), Cr(III) and Cr(VI), respectively. The accuracy of the method was evaluated and confirmed by addition/recovery tests. The recoveries obtained varied from 81% to 110%. The proposed method was applied to the speciation analysis of arsenic and chromium in commercially available iron supplements acquired in several cities in Brazil and Spain. The content of the species ranged from 0.01 to 1.3µgg(-1) for arsenic, and from 0.4 to 61.2µgg(-1) for chromium. Copyright © 2017 Elsevier B.V. All rights reserved.

    When the clinical crowns of teeth are dimensionally inadequate, esthetically and biologically acceptable restoration of these dental units is difficult. Often an acceptable restoration cannot be accomplished without first surgically increasing the length of the existing clinical crowns; therefore, successful management requires an understanding of both the dental and periodontal parameters of treatment. The complications presented by teeth with short clinical crowns demand a comprehensive treatment plan and proper sequencing of therapy to ensure a satisfactory result. Visualization of the desired result is a prerequisite of successful therapy. This review examines the periodontal and restorative factors related to restoring teeth with short clinical crowns. Modes of therapy are usually combined to meet the biologic, restorative, and esthetic requirements imposed by short clinical crowns. In this study various methods for treating short clinical crowns are reviewed, the role that restoration margin location play in the maintenance of periodontal and dental symbiosis and the effects of violation of the supracrestal gingivae by improper full-coverage restorations has also been discussed. Key words:Short clinical crown, surgical crown lengthening, forced eruption, diagnostic wax up, alveoloplasty, gingivectomy. PMID:24558561

    This work was performed in the frame of a Coordinated Research Project (CRP) with IAEA whose objective was to extend the scope of activities carried out by national TLD-based networks from dosimetry audit for rectangular radiation fields to irregular and small fields relevant to modern radiotherapy. External audit is a crucial element in QA programmes for clinical dosimetry in radiotherapy, therefore a methodology and procedures were developed and were made available for dose measurement of complex radiotherapy parameters used for cancer treatment. There were three audit steps involved in this CRP: TLD based dosimetry for irregular MLC fields for conformal radiotherapy, dosimetry in the presence of heterogeneities and 2D MLC shaped fields relevant to stereotactic radiotherapy and applicable to dosimetry for IMRT. In addition, a new development of film-based 2D dosimetry for testing dose distributions in small field geometry was included. The plan for each audit step involved a pilot study and a trial audit run with a few local hospitals. The pilot study focused on conducting and evaluation of the audit procedures with all participants. The trial audit run was the running of the audit procedures by the participants to test them with a few local radiotherapy hospitals. This work intends to provide audits which are much nearer clinical practice than previous audits as they involve significant testing of Tps methods, as well as verifications to determinate whether hospitals can correctly calculate dose delivery in radiation treatments.

    Migraine is the most common form of headache disorder globally. The etiology of migraine is multifactorial, with genetic components and environmental interactions considered to be the main causal factors. Some researchers postulate that deficits in mitochondrial energy reserves can cause migraine or an increase in homocysteine levels can lead to migraine attacks; therefore, vitamins could play a vital role in migraine prevention. For instance, riboflavin influences mitochondrial dysfunction and prevents migraine. Genes such as flavoenzyme 5,10-methylenetetrahydrofolate reductase (MTHFR), especially the C677T variant, have been associated with elevated plasma levels of homocysteine and migraine with aura. Homocysteine catalyzation requires the presence of vitamins B6, B12, and folic acid, which can decrease the severity of migraine with aura, making these vitamins potentially useful prophylactic agents for treating migraine with aura. Menstrual migraine, on the other hand, is associated with increased prostaglandin (PG) levels in the endometrium, indicating a role for vitamin E, which is an anti-PG. Vitamin C can also be used as a scavenger of reactive oxygen species for treating neurogenic inflammation in migraine patients. This paper reviews possible therapies based on vitamin supplementation for migraine prophylaxis, focusing on migraine with aura and menstrual migraine.

    Four laboratory-scale baffled subsurface-flow constructed wetlands (BSCWs) were established for the treatment of greenhouse wastewater containing high levels of nitrate and sulfate in the present study. Each BSCW microcosm involved a treatment zone and another post-treatment zone with a surface area ratio of 2:1. Evenly mixed straws of carnation and rose (w/w: 1/1), two common ornamental flowers, were supplemented as an organic carbon source into the treatment zone through a hydrolysis zone (CW 1), decentralized vertically installed perforated pipes (CW 2), and centralized pipes (CW 3 in the figures), except the blank system. Removals and transformations of nitrogen and sulfate as well as carbon release in the BSCWs were investigated and comparatively assessed. Results showed that the supplements of flower straws could greatly enhance both the nitrate and sulfate removals, and good performance was achieved during the beginning operation period of 30 days, followed by decline due to insufficient organic carbon supply. Nitrate removal efficiency was significantly higher and more stable compared to sulfate. The highest removal rates of nitrate and sulfate were achieved in the CW 3, with a mean value of 4.33 g NO3(-)-N·m(-2) d(-1) and 2.74 g SO4(2-)-S·m(-2) d(-1), respectively, although the differences among the experimental microcosms were not statistically significant. However, almost the same TN removal rate (3.40-3.47 g N·m(-2) d(-1)) was obtained due to the productions of NO2(-)-N and NH4(+)-N and leaching of organic N from the straws. High contents of organic carbon and colored substance were leached from the straws during the initial 10 days, but dropped rapidly to low levels, and could hardly determined after 30 days operation. The post-treatment zone could further eliminate various contaminants, but the capability was limited. Inorganic carbon (IC) concentration was detected to be a highly good indicator for the estimation of nitrate and sulfate

  1. Dosimetric Comparison of Two Craniospinal Radiotherapy Techniques for Treatment Optimization

    Directory of Open Access Journals (Sweden)

    Full Text Available Introduction: Orthogonal radial fields are those in which the central axes are perpendicular to each other. An example of these orthogonal fields is the set of craniospinal orthogonal fields that are used for radiotherapy of medulloblastoma. Craniospinal radial fields consist of two parallel-opposed fields for brain exposure and one or two posterior spinal fields for spinal cord exposure. The main problem in using these combinative fields is the overlap of radial fields, where they adjoin. Therefore, adjusting radial fields in craniospinal radiotherapy is of remarkable significance and can outstandingly affect the reduction of the side effects due to radiotherapy. In doing so, two different setups were used for craniospinal radiotherapy, and by using dosimetry in each adjustment in the junction region between brain and upper spine fields and in organs at risk, the results of the two adjustments were compared. Materials and Methods: Each one of these two setups was separately performed on a Rando phantom. In the first setup, the arrangement of radial fields was performed without the rotation of the treatment bed and the collimators of the brain fields. In the second setup, the arrangement of radial fields was performed using the rotation of the treatment bed and the collimators of brain fields. For dosimetry, GR-200 TLDs were used. For radiotherapy, a varian linac (2100 C/D Model was used. Results: The results of dosimetry in the brain CTV, junction of brain and upper spine fields, thyroid and heart in the first setup were equal to 105, 168, 46 and 44 cGy, respectively, and in second setup, 106, 140, 48 and 44 cGy, respectively. Absorbed dose to the testes in both setups was negligible.  Discussion and Conclusion: The results of dosimetry in both setups showed that angling the bed and the collimators for the brain fields prevents the overlap of radial fields and reduces the side effects due to radiotherapy.

  2. Role of Imaging Techniques in Percutaneous Treatment of Mitral Regurgitation.

    2016-04-01

    Mitral regurgitation is the most prevalent valvular heart disease in the United States and the second most prevalent in Europe. Patients with severe mitral regurgitation have a poor prognosis with medical therapy once they become symptomatic or develop signs of significant cardiac dysfunction. However, as many as half of these patients are inoperable because of advanced age, ventricular dysfunction, or other comorbidities. Studies have shown that surgery increases survival in patients with organic mitral regurgitation due to valve prolapse but has no clinical benefit in those with functional mitral regurgitation. In this scenario, percutaneous repair for mitral regurgitation in native valves provides alternative management of valvular heart disease in patients at high surgical risk. Percutaneous repair for mitral regurgitation is a growing field that relies heavily on imaging techniques to diagnose functional anatomy and guide repair procedures.

    Radiation treatment to the left breast is associated with increased cardiac morbidity and mortality. The deep inspiration breath-hold technique (DIBH) can decrease radiation dose delivered to the heart and this may facilitate the treatment of the internal mammary chain nodes. The aim of this review is to critically analyse the literature available in relation to breath-hold methods, implementation, utilisation, patient compliance, planning methods and treatment verification of the DIBH technique. Despite variation in the literature regarding the DIBH delivery method, patient coaching, visual feedback mechanisms and treatment verification, all methods of DIBH delivery reduce radiation dose to the heart. Further research is required to determine optimum protocols for patient training and treatment verification to ensure the technique is delivered successfully.

    Breast cancer treatment by the aromatase inhibitor Letrozole (LET) or Selective Estrogen Receptor Modulator Tamoxifen (TAM) can result in the onset of menopausal symptoms. Women often try to relieve these symptoms by taking menopausal supplements containing high levels of phytoestrogens. However, little is known about the potential interaction between these supplements and breast cancer treatment, especially aromatase inhibitors. In this study, interaction of phytoestrogens with the estrogen receptor alpha and TAM action was determined in an ER-reporter gene assay (BG1Luc4E2 cells) and human breast epithelial tumor cells (MCF-7). Potential interactions with aromatase activity and LET were determined in human adrenocorticocarcinoma H295R cells. We also used the previously described H295R/MCF-7 co-culture model to study interactions with steroidogenesis and tumor cell proliferation. In this model, genistein (GEN), 8-prenylnaringenin (8PN) and four commercially available menopausal supplements all induced ER-dependent tumor cell proliferation, which could not be prevented by physiologically relevant LET and 4OH-TAM concentrations. Differences in relative effect potencies between the H295R/MCF-7 co-culture model and ER-activation in BG1Luc4E2 cells, were due to the effects of the phytoestrogens on steroidogenesis. All tested supplements and GEN induced aromatase activity, while 8PN was a strong aromatase inhibitor. Steroidogenic profiles upon GEN and 8PN exposure indicated a strong inhibitory effect on steroidogenesis in H295R cells and H295R/MCF-7 co-cultures. Based on our in vitro data we suggest that menopausal supplement intake during breast cancer treatment should better be avoided, at least until more certainty regarding the safety of supplemental use in breast cancer patients can be provided.

    Background Vitamin D supplementation is believed to be beneficial in the treatment of patients with tuberculosis (TB),however,results from clinical trials have been inconclusive.Methods We performed a systematic literature search across MEDLINE,EMBASE,the Cochrane Central Register of Controlled Trials,Springer,EBSCO,ProQuest,HighWire Press,and Web of Science,published as of December 2013.We individually inspected citations and extracted data independently.We estimated pooled risk ratios (RR) and 95% confidence intervals (CI) using random-effect models.We also assessed risk of bias using the Jadad scale and the quality of the evidence using GRADE.We included all randomized controlled trials comparing vitamin D with or without standard TB therapy or placebo.Results A total of five studies were analyzed in our meta analysis covering 841 newly-diagnosed TB cases.Patients receiving vitamin D supplementation had a 39% reduced risk of sputum smear or culture positive after six weeks of antiTB treatment than those in the control group,although this is not statistically significant (pooled RR 0.61,95% CI 0.24 to 1.56,P=0.30).Apart from an increased serum vitamin D level in the supplement group after eight weeks of treatment there was no evidence of any additional adverse effects related to vitamin D.Conclusions The meta analysis results indicate that vitamin D supplementation does not seem to have any beneficial effect in the treatment of TB.Future rigorous randomized controlled trials are needed to explore whether the supplementation of vitamin D could shorten treatment duration and to confirm whether the polymorphisms of vitamin D receptor have any potentially beneficial effect.

    Silver mediated electrochemical oxidation technique has been considered one of promising candidates for alpha-bearing waste treatment. Destruction tests of organic compounds, such as insoluble tannin, TBP and dodecane, were carried out by this technique and the experimental data such as destruction rates, current efficiencies and intermediates were obtained. These compounds could be completely mineralized without the formation of reactive organic nitrate associated to safety hazards. On the basis of these results, the applicability of silver mediated electrochemical oxidation technique to waste treatment in NUCEF was evaluated. (authors)

    Illegally adulterated dietary supplements are an increasing problem worldwide. One of the important groups of often adulterated products are the dietary supplements, sold for the treatment of pain. These often contain analgesics, a heterogeneous group of molecules, containing both hydrophilic and hydrophobic compounds. The development of a screening method for these components, especially when mass spectrometric detection is not available, necessitates chromatographic separation, difficult to achieve with traditional chromatographic columns. In this paper Stationary Phase Optimised Selectivity Liquid Chromatography was used for the development of a screening method for nine analgesics, codeine and caffeine, often present in this type of dietary supplements. The method shows a good separation of all the compounds, allowing the screening to be performed with diode array detection and is fully compatible with mass spectrometry. The method was validated for its selectivity following the guidelines as described for the screening of pesticide residues and residues of veterinary medicines in food.

    Full Text Available We investigated the clinical usefulness of oral supplementation with a combination product containing alpha-lipoic acid, curcumin phytosome, and B-group vitamins in 180 patients with carpal tunnel syndrome (CTS, scheduled to undergo surgical decompression of the median nerve. Patients in Group A (n=60 served as controls and did not receive any treatment either before or after surgery. Patients in Group B (n=60 received oral supplementation twice a day for 3 months both before and after surgery (totaling 6 months of supplementation. Patients in Group C (n=60 received oral supplementation twice a day for 3 months before surgery only. Patients in Group B showed significantly lower nocturnal symptoms scores compared with Group A subjects at both 40 days and 3 months after surgery (both P values <0.05. Moreover, patients in Group B had a significantly lower number of positive Phalen’s tests at 3 months compared with the other study groups (P<0.05. We conclude that oral supplementation with alpha-lipoic acid, curcumin phytosome, and B-group vitamins twice a day both before and after surgery is safe and effective in CTS patients scheduled to undergo surgical decompression of the median nerve.

  20. A Proposed Molecular Mechanism of High-Dose Vitamin D3 Supplementation in Prevention and Treatment of Preeclampsia

    Directory of Open Access Journals (Sweden)

    Piotr Zabul

    2015-06-01

    Full Text Available A randomized prospective clinical study performed on a group of 74 pregnant women (43 presenting with severe preeclampsia proved that urinary levels of 15-F2t-isoprostane were significantly higher in preeclamptic patients relative to the control (3.05 vs. 2.00 ng/mg creatinine. Surprisingly enough, plasma levels of 25-hydroxyvitamin D3 in both study groups were below the clinical reference range with no significant difference between the groups. In vitro study performed on isolated placental mitochondria and placental cell line showed that suicidal self-oxidation of cytochrome P450scc may lead to structural disintegration of heme, potentially contributing to enhancement of oxidative stress phenomena in the course of preeclampsia. As placental cytochrome P450scc pleiotropic activity is implicated in the metabolism of free radical mediated arachidonic acid derivatives as well as multiple Vitamin D3 hydroxylations and progesterone synthesis, we propose that Vitamin D3 might act as a competitive inhibitor of placental cytochrome P450scc preventing the production of lipid peroxides or excess progesterone synthesis, both of which may contribute to the etiopathogenesis of preeclampsia. The proposed molecular mechanism is in accord with the preliminary clinical observations on the surprisingly high efficacy of high-dose Vitamin D3 supplementation in prevention and treatment of preeclampsia.

    Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), (n-3) fatty acids from fish oil, have immune-modulating effects and may improve nutritional status in cancer. The objective of this study was to investigate the effects of an oral nutritional supplement containing (n-3) fatty acids on nutritional status and inflammatory markers in patients with non-small cell lung cancer (NSCLC) undergoing multimodality treatment. In a double-blind experiment, 40 patients with stage III NSCLC were randomly assigned to receive 2 cans/d of a protein- and energy-dense oral nutritional supplement containing (n-3) fatty acids (2.0 g EPA + 0.9 g DHA/d) or an isocaloric control supplement. EPA in plasma phospholipids, energy intake, resting energy expenditure (REE), body weight, fat free mass (FFM), mid-upper arm circumference (MUAC), and inflammatory markers were assessed. Effects of intervention were analyzed by generalized estimating equations and expressed as regression coefficients (B). The intervention group (I) had a better weight maintenance than the control (C) group after 2 and 4 wk (B = 1.3 and 1.7 kg, respectively; P nutritional supplement containing (n-3) fatty acids beneficially affects nutritional status during multimodality treatment in patients with NSCLC.

    Full Text Available [Pseudo]obsessions therapy in patients with endogenous diseases of schizophrenic round accompanied with difficulties, caused by both psycho etio pathogenetic features of the disease. Disadvantages of the existing methods of therapy are associated with therapeutic conflict between two nosologies. Aim: to develop and test etiopsychopathogenetic technique "Subliminal verbal suggestion for the treatment of [pseudo]obsessions" as a subsidiary method of treatment of schizophrenia patients with [pseudo] obsessions in the structure of the disease. Methods and results. 137 patients who underwent hospital treatment 65 schizophrenia patients (F20 with the [pseudo]obsessive symptoms in the structure of the disease were examined on the basis of Public Health Institution «Regional clinical mental hospital» of the Zaporizhzhian regional council. 30 patients received standard pharmacotherapy (antipsychotic drugs according to clinical protocols that was combined with proposed technique "Subliminal verbal suggestion for the treatment of [pseudo]obsessions". The comparison group consisted of 35 patients treated with the use of standard pharmacotherapy: antipsychotic drugs. The next methods were used: medical history assessment, follow-up, clinical-psychopathological, psychodiagnostic. "Subliminal verbal suggestion for the treatment of [pseudo]obsessions" technique was developed. This technique is a combination of suggestion in the waking state and neurolinguistic programming, implemented with specially compiled auditory complex listening. The main therapeutic component s realized through the subthreshold perception of the verbal formulas that are unavailable to awareness.

    Details of piriformis syndrome, including the proper diagnosis and most effective form of treatment, continue to be controversial. While the cause, diagnosis, and treatment of piriformis syndrome remain elusive, many studies have been conducted to investigate newly developed diagnostic techniques as well as various treatment options for piriformis-induced sciatica. Despite the quantity of literature, few studies have demonstrated statistically significant results that support one form of treatment over another. Thus, despite the evidence supporting the newer treatment methodologies for piriformis syndrome, research should continue. It is important not only to evaluate treatment outcomes based on associated pain relief, but also to investigate the functional and anatomical return that patients experience from these studied treatments in order to fully explore the most effective form of therapy for piriformis syndrome.

    Our treatment technique for patients with extensive chest wall disese is presented. A rotational center-blocked radiation field is used to cover the large tumor volume to a dose with +/- 10% while sparing the lungs and the spinal cord. The center block is tapered to match both the patient's mediastinal slope in the sagittal plane and the outline of the lungs in the coronal plane. Ten patients treated with this technique to a tumor dose of 50 Gy tolerated the treatment well, despite a high integral dose. The local responses were excellent, particularly in view of the initial extent of the disease.

    To review the application progress of minimally invasive technique in the treatment of calcaneus fractures and to analyze the advantages and disadvantages of each method as well as to predict the trend of development in the field. Domestic and abroad literature concerning the minimally invasive technique applied in calcaneus fractures in recent years was reviewed extensively and analyzed thoroughly. There are both advantages and limitations of each minimally invasive technique including percutaneous reduction and fixation, limited incision, external fixator, arthroscopic assisted reduction, and balloon expansion reduction. But every technique is developing rapidly and becoming more and more effective. A variety of minimally invasive technique can not only be used independently but also can be applied jointly to complement one another. It needs further study how to improve the effectiveness and expand the indications. And the theoretical basis of evidence-based medicine needs to be provided more.

    Objective:To observe the clinical therapeutic effect of Ba-He technique of acupuncture in the treatment of knee osteoarthritis. Methods: A total of 90 cases of knee osteoarthritis were evenly randomized into Ba-He technique group (observation group) and common technique group (control group), with 45 cases in each group. Zusanli (足三里 ST 36), Heding (鹤顶 EX-LE 2) and Dubi (犊鼻 ST 35) were punctured respectively in Ba-He technique and common technique in the two groups. The therapeutic effects of the two groups were compared after one course of treatment (10 sessions) in accordance with Japanese assessment criteria for knee-joint functions. Results: Aftertreatment, among the 74 and 71 affected knees in the observation and control groups, the therapeutic effect was excellent in 42 (56.8%) and 26 (36.6%) knees, fine in 14 (18.9%) and 20 (28.2%), OK in 10 (13.5%) and 11 (15.5%), and poor in 8 (10.8%) and 14 (19.7%) respectively. The therapeutic effect of the observation group was significantly better than that of control group (P<0.01). Conclusion: The Ba-He technique of acupuncture applied to the above-mentioned three acupoints exerted remarkable therapeutic effect for knee osteoarthritis, which is obviously better than that of the common needling technique.

In these studies, varying procedural techniques were utilized to ablate the nerves that innervate the facet joints. To date, no comparison studies have been performed to suggest superiority of one technique or even compare the prevalence of side effects and complications. Materials and methods: A retrospective chart review was performed on patients who underwent a lumbar facet denervation procedure. Each patient's chart was analyzed for treatment technique (early versus advanced Australian, preprocedural visual numeric scale (VNS score, postprocedural VNS score, duration of pain relief, and complications. Results: Pre- and postprocedural VNS scores and change in VNS score between the two groups showed no significant differences. Patient-reported benefit and duration of relief was greater in the advanced Australian technique group (P=0.012 and 0.022, respectively. The advanced Australian technique group demonstrated a significantly greater median duration of relief (4 months versus 1.5 months, P=0.022. Male sex and no pain-medication use at baseline were associated with decreased postablation VNS scores, while increasing age and higher preablation VNS scores were associated with increased postablation VNS scores. Despite increasing age being associated with increased postablation VNS scores, age and the advanced Australian technique were found to confer greater patient self-reported treatment benefit. Conclusion: The advanced Australian technique provides a significant benefit over the early Australian technique for the treatment of lumbar facet pain, both in

    Full Text Available The aim of this study was to evaluate the benefits and risks of omega-3 fatty acid supplementation in patients with chronic kidney disease. A systematic search of articles in PubMed, Embase, the Cochrane Library, and reference lists was performed to find relevant literature. All eligible studies assessed proteinuria, the serum creatinine clearance rate, the estimated glomerular filtration rate, or the occurrence of end-stage renal disease. Standard mean differences with 95% confidence intervals for continuous data were used to estimate the effects of omega-3 fatty acid supplementation on renal function, as reflected by the serum creatinine clearance rate, proteinuria, the estimated glomerular filtration rate, and relative risk. Additionally, a random-effects model was used to estimate the effect of omega-3 fatty acid supplementation on the risk of end-stage renal disease. Nine randomized controlled trials evaluating 444 patients with chronic kidney disease were included in the study. The follow-up duration ranged from 2 to 76.8 months. Compared with no or low-dose omega-3 fatty acid supplementation, any or high-dose omega-3 fatty acid supplementation, respectively, was associated with a lower risk of proteinuria (SMD: -0.31; 95% CI: -0.53 to -0.10; p=0.004 but had little or no effect on the serum creatinine clearance rate (SMD: 0.22; 95% CI: -0.40 to 0.84; p=0.482 or the estimated glomerular filtration rate (SMD: 0.14; 95% CI: -0.13 to 0.42; p=0.296. However, this supplementation was associated with a reduced risk of end-stage renal disease (RR: 0.49; 95% CI: 0.24 to 0.99; p=0.047. In sum, omega-3 fatty acid supplementation is associated with a significantly reduced risk of end-stage renal disease and delays the progression of this disease.

    This study compares three online image guidance techniques (IGRT) for prostate IMRT treatment: bony-anatomy matching, soft-tissue matching, and online replanning. Six prostate IMRT patients were studied. Five daily CBCT scans from the first week were acquired for each patient to provide representative ''snapshots'' of anatomical variations during the course of treatment. Initial IMRT plans were designed for each patient with seven coplanar 15 MV beams on a Eclipse treatment planning system. Two plans were created, one with a PTV margin of 10 mm and another with a 5 mm PTV margin. Based on these plans, the delivered dose distributions to each CBCT anatomy was evaluated to compare bony-anatomy matching, soft-tissue matching, and online replanning. Matching based on bony anatomy was evaluated using the 10 mm PTV margin (''bone10''). Soft-tissue matching was evaluated using both the 10 mm (''soft10'') and 5 mm (''soft5'') PTV margins. Online reoptimization was evaluated using the 5 mm PTV margin (''adapt''). The replanning process utilized the original dose distribution as the basis and linear goal programming techniques for reoptimization. The reoptimized plans were finished in less than 2 min for all cases. Using each IGRT technique, the delivered dose distribution was evaluated on all 30 CBCT scans (6 patientsx5CBCT/patient). The mean minimum dose (in percentage of prescription dose) to the CTV over five treatment fractions were in the ranges of 99%-100%(SD=0.1%-0.8%), 65%-98%(SD=0.4%-19.5%), 87%-99%(SD=0.7%-23.3%), and 95%-99%(SD=0.4%-10.4%) for the adapt, bone10, soft5, and soft10 techniques, respectively. Compared to patient position correction techniques, the online reoptimization technique also showed improvement in OAR sparing when organ motion/deformations were large. For bladder, the adapt technique had the best (minimum) D90, D50, and D30 values for 24, 17

  1. The feasibility of using Pareto fronts for comparison of treatment planning systems and delivery techniques.

    Pareto optimality is a concept that formalises the trade-off between a given set of mutually contradicting objectives. A solution is said to be Pareto optimal when it is not possible to improve one objective without deteriorating at least one of the other. A set of Pareto optimal solutions constitute the Pareto front. The Pareto concept applies well to the inverse planning process, which involves inherently contradictory objectives, high and uniform target dose on one hand, and sparing of surrounding tissue and nearby organs at risk (OAR) on the other. Due to the specific characteristics of a treatment planning system (TPS), treatment strategy or delivery technique, Pareto fronts for a given case are likely to differ. The aim of this study was to investigate the feasibility of using Pareto fronts as a comparative tool for TPSs, treatment strategies and delivery techniques. In order to sample Pareto fronts, multiple treatment plans with varying target conformity and dose sparing of OAR were created for a number of prostate and head & neck IMRT cases. The DVHs of each plan were evaluated with respect to target coverage and dose to relevant OAR. Pareto fronts were successfully created for all studied cases. The results did indeed follow the definition of the Pareto concept, i.e. dose sparing of the OAR could not be improved without target coverage being impaired or vice versa. Furthermore, various treatment techniques resulted in distinguished and well separated Pareto fronts. Pareto fronts may be used to evaluate a number of parameters within radiotherapy. Examples are TPS optimization algorithms, the variation between accelerators or delivery techniques and the degradation of a plan during the treatment planning process. The issue of designing a model for unbiased comparison of parameters with such large inherent discrepancies, e.g. different TPSs, is problematic and should be carefully considered.

    Acupuncture has served as a major complementary and alternative therapy that supplements conventional medicine and is the subject of growing public interest. This study was conducted to estimate the usage rate of acupuncture as a supplemental treatment in acute ischaemic stroke patients and to identify factors associated with the choice to use this therapy. Using the registry of stroke patients admitted to an academic medical centre in Korea, the use of acupuncture therapy was recorded and analysed, along with the patients' socio-demographic characteristics, hospital access variables, risk factors for ischaemic stroke and clinical characteristics. The data were analysed using descriptive statistics, chi-square tests and multiple logistic regression analyses. Of 2167 patients, 18% received acupuncture therapy. The choice of acupuncture therapy was significantly associated with stroke severity as well as gender, age, geographical residence and previous history of stroke. After controlling for other significant factors, there was an approximately 3.4-fold greater usage in patients with moderately severe strokes (95% confidence interval (CI)=2.5-4.6) and 4.1-fold greater usage in patients with severe strokes (95% CI=2.7-6.4). The findings provide a better understanding of patients' utilization of acupuncture therapy as a supplement to conventional medical treatments and of factors associated with the utilization of acupuncture in patients with acute ischemic stroke. Strategic implications of acupuncture therapy are suggested for both health-care providers and policy makers. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Recalcitrant warts remain a challenging problem to treat, with considerable morbidity for patients. Our technique uses the carbon dioxide (CO2) laser as a bloodless scalpel to excise and treat recalcitrant warts. This paper reviews the results of patients with recalcitrant warts treated by the senior author using this technique. A retrospective case note review and questionnaire-based survey of patients treated by this technique. Seventy-one recalcitrant warts treated in 22 patients, all as day case procedures. A total of 54.5% of patients had complete remission after one treatment and the average length of follow-up was 71.5 months. Recurrence occurred on average 5.29 months following treatment. Of those patients, 90% were successfully retreated, giving an overall rate of 95.5%. In total, 46.7% of patients were left with scarring, but all felt this was acceptable given the benefits of the treatment, and 80.0% of patients would have the procedure again. Four patients had spontaneous regression of warts at other body sites not treated with the CO2 laser. This study illustrates the efficacy of our technique with a favourable outcome comparable to published studies. Recurrence occurred within 12 months; therefore, we would recommend this as a minimum follow-up period. In addition, the disappearance of warts at distant sites suggests that the effects of the CO2 laser therapy modulate the immune system, thereby extending it beyond simple excision or ablation.

    Free crown tipping can be useful when teeth do not erupt in their physiologic sequence and a real intraosseous migration and eruption of a single tooth into a distant ectopic position can be observed. This article presents a case of an ectopic mandibular lateral incisor treated early, with the light-force technique and uncontrolled forces, and finished with the bidimensional edgewise appliance. A Caucasian female patient, 10 years 10 months of age, had a mandibular left lateral incisor displacement, with the lateral incisor crown positioned mesial to left second primary molar. An early treatment was planned to correct the mandibular left lateral incisor displacement and to allow proper eruption of the mandibular left canine and first premolar. A second phase of treatment, in permanent dentition, was planned for the dental Class II subdivision on the right and deep bite correction. Phase 1 treatment was completed after 10 months; phase 2 treatment was initiated in the permanent dentition and lasted 18 months. Treatment achieved the following outcomes: (1) mandibular lateral incisor in corrected position; (2) full canine and molar Class I relationship; (3) overjet and overbite within the normal limits; (4) symmetric arches; and (5) a balanced profile. The radiograph evaluation revealed good root parallelism and mandibular left lateral incisor light root resorption. The light-force technique is not only a possible alternative but the ideal appliance for treatment in the mixed dentition, when the permanent teeth should be controlled.

    Full Text Available Objective. To choose the optimum technique of general anesthesia in the surgical treatment of patients with postinfarct left ventricular aneurysms (PLVA.Materials and methods. Fifty-four patients operated on for PLVA were examined. They were divided into 4 groups according to the basic technique of general anesthesia: 1 intravenous anesthesia based on propofol and fentanyl; 2 inhalation sevoflurane anesthesia with fentanyl enhancement of the analgesic component; 3 inhalation isoflurane anesthesia with fentanyl enhancement of the analgesic component; 4 general anesthesia in combination with epidural blockade. Central hemodynamics was investigated by the thermodilution technique and the perioperative period was also studied.Results and discussion. None of the general anesthesia techniques affected the development of perioperative complications. However, with decreased myocardial reserves, high thoracic epidural anesthesia should be applied with caution as it causes a significant desympathization, which may lead to impairments of the autoregulatory mechanisms of coronary blood flow and aggravate existing contractile disorders. Intravenous and inhalation anesthesia techniques provide a fair hemodynamic stability at all stages of surgical treatment. Inhalation anesthesia has a number of advantages: less cost and the possibility of rapid activation of patients in the early postoperative period.

    To define the best technique for the surgical treatment of supracondylar fracture of the humerus (SFH) in children, evaluating percutaneous pinning with side wires vs. cross-pinning. Randomized controlled trials using the Medline, CAPES, and BIREME. The criteria for inclusion of articles criteria were: (1) randomized controlled trials (RCTs) comparing percutaneous wire fixation techniques, (2) SFH Gartland II B, III, and IV, and (3) children aged 1-14 years. The following were used as main variables: incidence of iatrogenic injury to the ulnar nerve and loss reduction. Eight studies were selected (521 patients) comparing surgical treatment with pinning in supracondylar fracture of the humerus in children Gartland II type B, III or IV. Iatrogenic injury to the ulnar nerve was greater with the cross-pinning technique, with RR 0.28 and p = 0.03, while the mini-open technique presented RR 0.14 and p = 0.2. A statistically significant greater loss of reduction in the lateral pinning was observed in FSU Gartland III and IV(p = 0.04). Based upon this meta-analysis of prospective randomized clinical trials, the following is recommended: (1) percutaneous pinning with lateral wires in supracondylar fractures of the humerus in children classified as Gartland II type B; (2) use of crossed wires for Gartland type III or IV, using the mini-open technique for the medial wire.

    Full Text Available Aim. Surgical treatment of chondromalacia of knee joint cartilage is an actual problem of the modern orthopedics because the means of conservative therapy can be realized at an initial stage only and almost exhausted at the further ones. Imperfections of palliative surgical techniques are the short-term clinical effect and pathogenetic baselessness because surgical procedure is not directed on reparation of cartilaginous tissue. For today there are a lot of transplantation techniques that are used for biological renewal of articular surface with formation of hyaline or at least hyaline-like cartilage. The deep forage of cartilage defect bottom to the medullary canal is a perspective and priority technique.Methods. The results of treatment of 61 patients with chondromalacia of knee joint of 3-4 degree according to R. Outerbridge are the base of the work. 20 patients of every group underwent microfracturization of cartilage defect bottom and subchondral forage of defect zone. 21 patients underwent the deep forage of defect zone of knee joint according to an offered technique.Result. The results of treatment with microfracturization, subchondral forage and deep forage of defect zone indicate the more strong clinical effect especially in the last clinical group where good and satisfactory results ratios in the term of observation 18 and 24 month remain stable.Conclusions. Deep forage of cartilage defects zone is the most adequate reparative technique of the surgical treatment of local knee joint cartilage defects. Owing to this procedure the number of cells of reparative chondrogenesis predecessors is realized

    Insufficiency fractures of the pelvis, sacrum, spine, and long bones are painful, debilitating, and are common consequences of osteoporosis. Conventional treatment for these fractures varies from conservative therapy to surgery with plate and screw fixation. The former fails to address the underlying problem of fracture and frequently does not alleviate symptoms, while the latter is invasive and not always possible in older populations with low bone density and numerous co-morbidities. Osseous augmentation with polymethylmethacrylate (PMMA) has been used for over two decades to treat fractures related to osteoporosis, but has not been commonly used to treat fractures outside of the vertebral bodies. Osseous augmentation with PMMA is an image-guided procedure and various techniques have been utilized to treat fracture in different locations. We describe various techniques for image-guided osseous augmentation and treatment of insufficiency fractures with bothPMMA and allograft bone for fractures of the pelvis including sacrum, acetabulum, pubic symphysis, pubic rami ilium; appendicular skeleton including distal radius, proximal femur, and vertebral body. We also describe the potential risks and complications associated with percutaneous treatment of insufficiency fractures and techniques to avoid the pitfalls of the various procedures. We will present the process for patient follow-up and data regarding the pre- and postprocedure pain response in patients undergoing treatment for pelvic insufficiency fractures. (orig.)

    2014-11-01

    Full Text Available Background: The role of micronutrient status for the incidence and clinical course of cutaneous leishmaniasis is not much studied. Still zinc supplementation in leishmaniasis has shown some effect on the clinical recovery, but the evidence in humans is limited. Objective: To compare biochemical nutritional status in cutaneous leishmaniasis patients with that in controls and to study the effects of zinc supplementation for 60 days. Design: Twenty-nine patients with cutaneous leishmaniasis were treated with antimony for 20 days. Fourteen of them got 45 mg zinc daily and 15 of them got placebo. Biomarkers of nutritional and inflammatory status and changes in size and characteristics of skin lesions were measured. Results: The level of transferrin receptor was higher in patients than in controls but otherwise no differences in nutritional status were found between patients and controls. No significant effects of zinc supplementation on the clinical recovery were observed as assessed by lesion area reduction and characteristics or on biochemical parameters. Conclusions: It is concluded that nutritional status was essentially unaffected in cutaneous leishmaniasis and that oral zinc supplementation administered together with intramuscular injection of antimony had no additional clinical benefit.

    This is to report the case of a ten year old child affected by a numeric dental anomaly showing the pathologic condition characterised by the simultaneous presence of supernumerary and supplemental teeth. The anomaly was analysed to plan the best surgical and orthodontic treatments. Dental history, clinical and instrumental examinations were made to perform a correct orthodontic examination and diagnosis. A young patient was affected by numeric dental anomaly in the upper jaw. We observed a high number of teeth, specifically two normally formed supplemental lateral permanent incisors and an unerupted mesiodens placed between the upper central incisors. Firstly, the supplemental lateral teeth were extracted. This surgical therapy and the application of a space maintainer were made to permit the eruption of the permanent canines. Then the mesiodens also underwent surgical treatment (i.e. extraction). Eventually, physiologic eruption of permanent teeth was allowed by the planned surgical-orthodontic treatment. Aim of the surgical-orthodontic treatment was extraction of the unerupted supernumerary teeth to obtain the physiologic eruption of the permanent ones. Orthodontic treatment is important to solve malocclusions and maintaining the space for the eruption of permanent teeth. Aesthetics and function are two important parameters in modern dentistry. All clinicians should try to make a correct and rational diagnosis for both simple and complex dental pathologies. Particularly in young children, invasive and surgical disinclusive techniques can be substituted by interceptive orthodontic treatments.

    Common bile duct stones (CBDSs) may occur in up to 3%-14.7% of all patients for whom cholecystectomy is preformed. Patients presenting with CBDS have symptoms including: biliary colic, jaundice, cholangitis, pancreatitis or may be asymptomatic. It is important to distinguish between primary and secondary stones, because the treatment approach varies. Stones found before, during, and after cholecystectomy had also differing treatments. Different methods have been used for the treatment of CBDS but the suitable therapy depends on conditions such as patient' satisfaction, number and size of stones, and the surgeons experience in laparoscopy. Endoscopic retrograde cholangiopancreatography with or without endoscopic biliary sphincterotomy, laparoscopic CBD exploration (transcystic or transcholedochal), or laparotomy with CBD exploration (by T-tube, C-tube insertion, or primary closure) are the most commonly used methods managing CBDS. We will review the pathophysiology of CBDS, diagnosis, and different techniques of treatment with especial focus on the various surgical modalities.

    Constructed wetlands (CWs) have been used as an alternative to conventional technologies for wastewater treatment for more than five decades. Recently, the use of various modified CWs to improve treatment performance has also been reported in the literature. However, the available knowledge on various CW technologies considering the intensified and reliable removal of pollutants is still limited. Hence, this paper aims to provide an overview of the current development of CW strategies and techniques for enhanced wastewater treatment. Basic information on configurations and characteristics of different innovations was summarized. Then, overall treatment performance of those systems and their shortcomings were further discussed. Lastly, future perspectives were also identified for specialists to design more effective and sustainable CWs. This information is used to inspire some novel intensifying methodologies, and benefit the successful applications of potential CW technologies.

    Lomano, J M

    1988-07-01

    Endometrial ablation performed with the Nd:YAG laser was developed to treat patients with chronic menorrhagia as an alternative to hysterectomy. The original dragging technique may result in an obscured operating field and fluid overload. This study compares results of endometrial ablation performed in 62 patients. The first 17 procedures were performed by use of the dragging technique; the last 45 procedures were performed with a blanching technique. Both procedures were performed at the same institution and by the same surgeon. Sixty-five percent of patients undergoing the blanching technique became amenorrheic after the procedure versus 12% of those undergoing the dragging technique. Moreover, the blanching technique required less time, fewer joules of energy, and resulted in less fluid absorption by the patient. The blanching technique is apparently more effective, easier to accomplish, and safer for the patient than the dragging technique.

    Purpose. The purpose of this study is to investigate whether double-row suture technique is a better option for the treatment of Haglund syndrome than single-row suture technique regarding the surgical outcomes. Methods. Thirty-two patients with Haglund syndrome were recruited in this study. Patients were divided into Group 1 (treated with single-row suture technique) and Group 2 (treated with double-row suture technique). There were 16 patients in each group. The AOFAS-ankle-hindfoot scale, VISA-A scores, and Arner-Lindholm standard were used to assess the clinical outcomes. The pre- and postoperative X-rays were used to assess the radiological outcome. Results. Both AOFAS-ankle-hindfoot scale score and VISA-A score had varying degrees of improvement in both groups. In latest follow-up assessment, the Arner-Lindholm standard investigation showed there were 7 excellent, 7 good, and 2 bad outcomes in Group 1 and 12 excellent and 4 good outcomes in Group 2. In Group 2 patients, there were no more posterosuperior bony prominence of the calcaneum in post-op X-rays and there were no recurrent cases. The ankle-related scale score was statistically significantly higher in Group 2 than in Group 1 (P = 0.029). Conclusion. The double-row suture technique seems to be a better option to treat Haglund syndrome than single-row suture technique.

    Full Text Available Tear trough deformity is a major concern in a lot of individuals seeking periorbital rejuvenation. A prominent tear trough deformity is characterised by a sunken appearance of the eye that results in the casting of a dark shadow over the lower eyelid, giving the patient a fatigued appearance despite adequate rest, and is refractory to attempts at cosmetic concealment. The tear trough deformity is a natural consequence of the anatomic attachments of the periorbital tissues. A variety of techniques have evolved to address this cosmetic issue. Traditional techniques relied on surgical excision of skin, muscle, and fat as well as chemical peels. Treatment is now tailored towards specific anatomic abnormalities and often employs multiple modalities including surgery, botulinum toxin, and replacement of volume. Various original research articles, text book publications and review articles were studied. Data specific to the historical aspect and anatomy of tear trough have been enumerated. Techniques of different authors were analysed and their results and complications have been summarised. The technique of the author has also been described here.

    Full Text Available Objective: Seborrheic keratosis is a benign epidermal tumour that is generally pigmented and develop from the proliferation of epidermal keratinocytes. In this study, two different techniques, spray or probe applications used cryotherapy during the treatment of seborrheic keratosis were compared in terms of efficiency and undesired effects. By this way, it is aimed to find the most suitable technique in seborrheic keratosis treatment. Method: Eighty lesions were included in the study with the diagnosis of seborrheic keratosis. These 80 lesions were divided randomly into two groups of 40; to one of which spray cryotherapy to the second cryotherapy with probe were applied. If clinical improvement were seen treatment was accepted as successful. The patiens were evaluated 2 and 4 months after the therapy for the comparison of two treatment. The patients in both groups scored their pain from 1 to 10 during the cryotherapy.Results: In the study, great success was achieved in the treatment of seborrheic keratosis by using different cryotherapy methods. All the patients in both groups were diagnosed with hipopigmentation. They were found to continue hipopigmentation in the second and fourth months. It was found that the intensity of the pain which those in the probe cryotherapy group suffered was significantly greater statistically.Conclusion: It was concluded that spray cryotherapy should be preferred since it was less painful and required less equipment than probe cryotherapy.

    2008-11-01

    Traumatic vascular injuries involving the extremity are rare and penetrating trauma accounts for the majority of such injuries. The remaining arterial injuries are as a result of either blunt or iatrogenic injuries. The rapid detection, localisation and characterisation of vascular injuries in patients who have a traumatic extremity injury is essential for the effective management and treatment of such injuries. This review will discuss the expanding role of multi-detector computed tomography angiography in diagnosing vascular injuries and its implications on conventional diagnostic angiography. The roles of other non-invasive imaging modalities are reviewed. The presentation and types of vascular injuries in blunt and penetrating injuries are discussed. While surgery remains the gold standard in the management of vascular extremity injuries it has significant morbidity rates. Endovascular techniques are increasingly being used for the treatment of vascular traumatic injuries and various techniques including balloon occlusion, embolisation and stent/stent graft placement are discussed.

    To assess the clinical effects of combined endoscopic-laparoscopic technique for one-stage treatment of cholelithiasis with concomitant choledocholithiasis. A retrospective analysis was conducted of the clinical data of 30 patients (Group A) with cholelithiasis and choledocholithiasis receiving one-stage laparoscopic cholecystectomy (LC) combined with intraoperative encoscopic retrograde cholangio-pancreatography (ERCP) and 32 patients (Group B) receiving LC combined with 1aparoscopic common bile duct exploration. The operative time, blood loss, conversion to open surgery rate, time to postoperative ambulation, calculi residual rate, hospitalization cost and length of hospital stay were analyzed comparatively. There were statistically differences between the two groups in hospitalization cost and length of hospital stay (P0.05). Combined endoscopic-laparoscopic techniques can be a safe and feasible option for one-stage treatment of concomitant cholelithiasis and choledocholithiasis to allow rapid postoperative recovery with a shortened hospital stay.

    Full Text Available Background: RapidArc is a volumetric modulated arc therapy (VMAT technique that can deliver conformal dose distribution to the target while minimizing dose to critical structures. The main purpose of this study was to compare dosimetric quality of full double arc (full DA, full single arc (full SA, and partial double arc (partial DA techniques in RapidArc planning of prostate cancer. Materials and Methods: Twelve cases of prostate cancer involving seminal vesicles were selected for this retrospective study. For each case, RapidArc plans were created using full DA (two full arcs, full SA (one full arc, and partial DA (two partial arcs with anterior and posterior avoidance sectors techniques. For planning target volume (PTV, the maximum and mean doses, conformity, and inhomogeneity indices were evaluated. For bladder and rectum, volumes that received 70, 50, 40, and 20 Gy (V 70Gy , V 50Gy , V 40Gy and V 20Gy , respectively, and mean dose were compared. For femoral heads, V 40Gy , V 20Gy , and mean dose were evaluated. Additionally, an integral dose and monitor units (MUs were compared for each treatment plan. Results: In comparison to full DA and full SA techniques, the partial DA technique was better in sparing of rectum and bladder but delivered higher femoral head dose, which was nonetheless within the planning criteria. No clear dosimetric differences were found between full DA and partial DA plans for dose conformity and target homogeneity. The number of MUs and integral dose were largest with the partial DA technique and lowest with the full SA technique. Conclusion: The partial DA technique provides an alternative RapidArc planning approach for low risk prostate cancer.

  9. An indirect veneer technique for simple and esthetic treatment of anterior hypoplastic teeth

    Directory of Open Access Journals (Sweden)

    Amit Khatri

    2010-01-01

    Full Text Available This study describes a technique for treating anterior hypoplastic teeth using indirect nanocomposite veneer restoration. The prime advantage of an indirect veneer technique is that it provides an esthetic and conservative result. One of the most frequent reasons that patients seek dental care is discolored anterior teeth. Although treatment options such as removal of surface stains, bleaching, microabrasion or macroabrasion, veneering, and placement of porcelain crowns are available, conservative approach such as veneer preserves the natural tooth as much as possible. Full veneers are recommended for the restoration of localized defects or areas of intrinsic discoloration, which are caused by deeper internal stains or enamel defects. Indirectly fabricated veneers are much less sensitive compared to a operator′s technique and if multiple teeth are to be veneered, indirect veneers can be usually placed much more expeditiously. Indirect veneers last much longer than the direct veneers. Therefore, indirectly fabricated veneers are more advantageous than directly fabricated veneers in many cases.

    1981-01-01

    The ability to predict a pion dose distribution in a patient is a major objective of the clinical trials at LAMPF. Accurate predictions are essential for evaluation of pion therapy. But accuracy must be in the context of clinical utility. That is, reasonable approximations must be made in calculational methods so that treatment planning can proceed in a timely and efficient manner. A few of the techniques and current developments used to achieve that objective are presented here.

    Full Text Available Objetives In the treatment of anterior shoulder instability there are have been described many surgical techniques, all of them with advantages and disadvantages. Our goal is to study the half term results on patients that underwent open Bristow-Latarjet surgery considering the preoperative ISIS value. Method This is a retrospective study of 33 patients that underwent open Bristow-Latarjet surgery in our center between 2005 and 2012. Average age of 33 (21-68 years and follow up of 6 (2-9 years. Results were taken by Rowe and Constant scores, DASH questionnaire and we also recorded a subjective assessment of the result by each patient. Results No recurrence was reported. No reoperations. Mean Rowe score was 74.6 (15-100 points and mean Constant score was 70 (32-98 points. In the disability questionnaire (DASH, the mean value was 22.9 (0-73 points. Seventy-nine percent of patients were satisfied with surgery result. The migration of a screw occurred in one patient Conclusions We believe that Bristow-Latarjet technique is a reliable technique, with few complications and with an low rate of recurrence in treatment of chronic shoulder instability as reported in literature. We believe, therefore, that it should be used as primary surgery in some cases and the preoperative ISIS is an excellent and simple guide to select correctly the surgical technique for each patient.

    This study evaluates the clinical outcomes of a novel tunnel-like surgical technique in the treatment of isolated deep intrabony defects. Twelve patients presenting with at least one isolated deep intrabony defect received regenerative periodontal treatment with "entire papilla preservation (EPP)" technique. Access to the intrabony defect for debridement was provided by a bevelled vertical releasing incision positioned in the buccal gingiva of the neighbouring inter-dental space. Following the elevation of a buccal flap, an inter-dental tunnel was prepared undermining the defect-associated papilla. Granulation tissue was removed, root surfaces were carefully debrided and bone substitutes and enamel matrix derivative were applied. Microsurgical suturing technique was used for optimal wound closure. Early healing was uneventful in all cases, and 100% wound closure was maintained during the entire healing period. At 1-year, there was significant attachment gain of 6.83±2.51 mm (p<0.001). The 7±2.8 mm reduction in probing depth was also significant (p<0.001), which was associated with minimal increase in gingival recession (0.16±0.38 mm, p=0.166). Tunnel-like "EPP" technique may limit the risk of wound failure particularly in the early healing phase, thereby preventing exposure of regenerative biomaterials, possibly enhancing stabilization of blood clot in deep intrabony defects and leading to optimal clinical outcomes. © 2017 John Wiley & Sons A/S.

    In the Bayer process of extraction of alumina from bauxite, the insoluble product generated after bauxite digestion with sodium hydroxide at elevated temperature and pressure is known as 'red mud' or 'bauxite residue'. This alumina refinery waste is highly alkaline in nature with a pH of 10.5-12.5 and is conventionally disposed of in mostly clay-lined land-based impoundments. The alkaline constituents in the red mud impose severe and alarming environmental problems, such as soil and air pollution. Keeping in view sustainable re-vegetation and residue management, neutralization/treatment of red mud using different techniques is the only alternative to make the bauxite residue environmentally benign. Hence, neutralization techniques, such as using mineral acids, acidic waste (pickling liquor waste), coal dust, superphosphate and gypsum as amenders, CO2, sintering with silicate material and seawater for treatment of red mud have been studied in detail. This paper is based upon and emphasizes the experimental work carried out for all the neutralization techniques along with a comprehensive review of each of the processes. The scope, applicability, limitations and feasibility of these processes have been compared exhaustively. Merits and demerits have been discussed using flow diagrams. All the techniques described are technically feasible, wherein findings obtained with seawater neutralization can be set as a benchmark for future work. Further studies should be focused on exploring the economical viability of these processes for better waste management and disposal of red mud.

    Photoacoustic (PA) techniques have been exploited for monitoring thermal treatments. However, PA signals depend not only on tissue temperature but also on tissue optical properties which indicate tissue status (e.g., native or coagulated). The changes in temperature and tissue status often occur simultaneously during thermal treatments, so both effects cause changes to PA signals. A new dual-wavelength PA technique to monitor tissue status independent of temperature is performed. By dividing the PA signal intensities obtained at two wavelengths at the same temperature, a ratio, which only depends on tissue optical properties, is obtained. Experiments were performed with two experimental groups, one with untreated tissue samples and the other with high-intensity focused ultrasound treated tissue samples including thermal coagulated lesion, using ex vivo porcine myocardium specimens to test the technique. The ratio of PA signal intensities obtained at 700 and 800 nm was constant for both groups from 25 to 43°C, but with distinct values for the two groups. Tissue alteration during thermal treatment was then studied using water bath heating of tissue samples from 35 to 60°C. We found that the ratio stayed constant before it exhibited a marked increase at around 55°C, indicating tissue changes at this temperature.

    Liver hydatidosis is a focal benign parasitic disease that still cause high rate of morbidity particularly in the Mediterranean area. A retrospective study comparing conservative and radical techniques in a General and Urgent Surgery operative unit was carried out in order to find signs of its surgical treatment. A total of 50 patients, 24 men and 26 women, who experienced a surgical treatment from 2000 to 2011, participated, and through the Fisher's Exact Test characteristics of the cysts, post-operative complications and relapse were compared. As a result, 29 patients undertook conservative surgery, while 21 radical surgery. There was a relationship between characteristics of the cysts and the technique chosen, (pcase (p<0.14). In conclusion, in a non hepato-bilio-pancreatic center a radical surgery including liver resection is suggested for left lobe's cysts, while a conservative technique tends to be more effective for right lobe's cysts mainly if complex. Consequently, patients with complicated presentation could explain why conservative treatment causes higher rate of morbidity.

    Full Text Available Background: Delayed intra-abdominal bleeding related to hepatic artery pseudoaneurysm is a potentially lethal complication after pancreaticoduodenectomy for pancreatic cancer. Locally advanced tumors, which result in vessel erosion or extensive operative skeletonization, may contribute to weakness of the arterial wall. Reoperation is often technically difficult with high rate of mortality; therefore, alternative less invasive options are ideal. Aims: The study was to present an alternative endovascular treatment of a large hepatic artery pseudoaneurysm after pancreatic resection for locally advanced multicystic adenocarcinoma. Materials and Methods: Transcatheteric mesenteric angiography with deployment of detachable coils in the pseudoaneurysm sac was utilized to manage the hepatic artery pseudoaneurysm. Results: Completion angiography confirmed cessation of contrast enhancement in the pseudoaneurysm sac with preservation of normal antegrade hepatic artery flow. Conclusion: Minimally invasive angiographic technique is the preferred treatment for hepatic artery pseudoaneurysm after pancreatic resections.

    Bud extracts, named also "gemmoderivatives", are a new category of natural products, obtained macerating meristematic fresh tissues of trees and plants. In the European Community these botanical remedies are classified as plant food supplements. Nowadays these products are still poorly studied, even if they are widely used and commercialized. Several analytical tools for the quality control of these very expensive supplements are urgently needed in order to avoid mislabelling and frauds. In fact, besides the usual quality controls common to the other botanical dietary supplements, these extracts should be checked in order to quickly detect if the cheaper adult parts of the plants are deceptively used in place of the corresponding buds whose harvest-period and production are extremely limited. This study aims to provide a screening analytical method based on UV-VIS-Fluorescence spectroscopy coupled to multivariate analysis for a rapid, inexpensive and non-destructive quality control of these products.

    Aim of the study The significance of nutritional supplements for immunity has been documented. Locally sourced extracts used in alternative medicine were studied to determine their potential effects on antibody production and humoral responses in viral challenged birds. Method Three hundred and eighty birds were distributed into 19 groups of 20 birds each. Following acclimatization for 16 days, they were fed with standard broilers feed and water ad libitum. Group A was supplemented with Aloe vera (AV) extract, group B was given Alma millsoni (AM) extract, group C was given Archachatina marginata (AMS) extract and group D was given Ganoderma lucidum (GL) extract, and group E was the control group. Extract concentrations of 50 mg, 100 mg and 150 mg were given to three subsets of each treatment group for 30 days. Birds were then challenged with intramuscular administration of 0.2 ml of 50% Embryo Lethal Dose of saline suspension of the challenge strain of Newcastle Disease Virus (NDV) on the 30th day, and were examined for clinical signs and symptoms. Serum from venous blood was used for antibody and immunological assay. Results Aloe vera at 50 µg and A. millsoni extracts supplementations yielded a significant antibody titre (p extract of Ganoderma and A. marginata, pretreatment with A. millsoni extract and a lower dosage of Aloe vera enhanced the ability to mount humoral responses against viral infection in broiler chickens.

    Wine by-products, in particular grape pomace, can be an important source of polyphenols and dietary fibers and are increasingly being used as a starting material in the industrial production of plant food supplements, such as other matrices containing biomolecules, with antioxidant properties. The risk associated with the consumption of these products was recently analyzed through a study of potential genotoxic and carcinogenic compounds that can be found in the marketed products. In particular, occurrence data about contamination with the mycotoxin ochratoxin A were also reported. This short review aims at giving an overview about the quality and benefits of these kinds of food supplements, and also about risks of incorrect use, focusing on the emerging need for stricter European regulations.

    Full Text Available Hybrid IMRT/VMAT technique which combined intensity modulated radiotherapy (IMRT and volumetric modulated arc therapy (VMAT was developed for the treatment of nasopharyngeal cancer (NPC. Two-full-arc VMAT (2ARC-VMAT, 9-field IMRT (9F-IMRT, and Hybrid IMRT/VMAT plans for NPC were compared in terms of the dosimetric quality, sparing of organs at risk (OARs, and delivery efficiency. The Hybrid IMRT/VMAT technique can improve the target dose homogeneity and conformity compared with 9F-IMRT and 2ARC-VMAT. It can reduce the dose delivered to the TMJ, mandible, temporal lobe, and unspecified tissue with fewer MUs compared with 9F-IMRT and dose delivered to parotids, brainstem, and spinal cord compared with 2ARC-VMAT technique. The mean delivery time of Hybrid plans was shorter than that of 9F-IMRT plans (408 s versus 812 s; P=0.00 and longer than that of 2ARC-VMAT plans (408 s versus 179 s; P=0.00. Hybrid IMRT/VMAT technique could be a viable radiotherapy technique with better plan quality.

    Full Text Available OBJECTIVE: The objective of this study was to compare the pain levels on opposite sides of the maxilla at needle insertion during delivery of local anesthetic solution and tooth preparation for both conventional and anterior middle superior alveolar (AMSA technique with the Wand computer-controlled local anesthesia application. MATERIAL AND METHODS: Pain scores of 16 patients were evaluated with a 5-point verbal rating scale (VRS and data were analyzed nonparametrically. Pain differences at needle insertion, during delivery of local anesthetic, and at tooth preparation, for conventional versus the Wand technique, were analyzed using the Mann-Whitney U test (p=0.01. RESULTS: The Wand technique had a lower pain level compared to conventional injection for needle insertion (p0.05. CONCLUSIONS: The AMSA technique using the Wand is recommended for prosthodontic treatment because it reduces pain during needle insertion and during delivery of local anaesthetic. However, these two techniques have the same pain levels for tooth preparation.

    Precision medicine is to customize the treatment options for individual patient based on the personal genome information. Colorectal cancer (CRC) is one of the most common cancer worldwide. Molecular heterogeneity of CRC, which includes the MSI phenotype, hypermutation phenotype, and their relationship with clinical preferences, is believed to be one of the main factors responsible for the considerable variability in treatment response. The development of powerful next-generation sequencing (NGS) technologies allows us to further understand the biological behavior of colorectal cancer, and to analyze the prognosis and chemotherapeutic drug reactions by molecular diagnostic techniques, which can guide the clinical treatment. This paper will introduce the new findings in this field. Meanwhile we integrate the new progress of key pathways including EGFR, RAS, PI3K/AKT and VEGF, and the experience in selective patients through associated molecular diagnostic screening who gain better efficacy after target therapy. The technique for detecting circulating tumor DNA (ctDNA) is introduced here as well, which can identify patients with high risk for recurrence, and demonstrate the risk of chemotherapy resistance. Mechanism of tumor drug resistance may be revealed by dynamic observation of gene alteration during treatment.

    The presence of bacteria in semen could induce impairment of sperm morphology, alteration of sperm function and mechanical or functional obstruction of the seminal tract. The term of bacteriospermia does not signify infection. Bacteriospermia and male accessory gland infection (MAGI) have indeed to be distinguished. They may lead both to male infertility but their diagnosis and treatment options differ. This review summarizes effects of bacteria and leucocytospermia on sperm parameters and functions. Then, indications, benefits and risks of treatment of bacteriospermia and MAGI, in assisted reproductive techniques (ART) will be discussed. For bacteria commonly observed in semen, this review aims at defining some thresholds above which a treatment is required. These thresholds were established according to literature, according to French microbiology society and in function of our usual practice. This review should help practitioners of reproductive medicine to take care of bacteriospermia in semen.

    Full Text Available Pediatric acetabular fractures are rare, and anterior column fractures are even rarer. Generally, conservative treatment is applied. If there is displacement of more than 2 mm or findings of instability or fragments within the joint, then surgical treatment is applied. Anterior and posterior approaches may be used in surgical treatment. With pediatric patients, even greater care should be taken in the choice of surgery to be performed according to the fracture pattern to avoid postoperative triradiate cartilage damage. Therefore, minimally invasive surgery is more appropriate. We herein present a case of an acetabulum anterior column posterior hemitransverse fracture following a traffic accident, which was treated surgically using a modified Stoppa (technique approach.

    Oral ranulas are caused by extravasation of mucus from the sublingual glands, and the preferred treatment varies. We have developed a two-incision fistula operation for their treatment, and in this clinical study we have evaluated the efficacy and safety of this approach. Twelve patients with oral ranulas confirmed by fine needle aspiration cytology were enrolled and gave their consent to be treated by our new technique. The clinical outcomes and complications were evaluated during a period that ranged from 8-24 months. Nine ranulas became smaller and gradually disappeared, and there were no complications or injury to Wharton's duct. Three ranulas recurred, but disappeared after a second operation. The two-incision fistula operation can be effective and safe as an initial treatment for oral ranulas, and the method may become the preferred management for retention cysts.

    Full Text Available Low back pain is one of the most common ailments in the general population, which tends to increase in severity along with aging. While few patients have severe enough symptoms or underlying pathology to warrant surgical intervention, in those select cases treatment choices remain controversial and reimbursement is a substancial barrier to surgery. The object of this study was to examine outcomes of discogenic back pain without radiculopathy following minimally-invasive lateral interbody fusion. Twenty-two patients were treated at either one or two levels (28 total between L2 and 5. Discectomy and interbody fusion were performed using a minimallyinvasive retroperitoneal lateral transpsoas approach. Clinical and radiographic parameters were analyzed at standard pre- and postoperative intervals up to 24 months. Mean surgical duration was 72.1 minutes. Three patients underwent supplemental percutaneous pedicle screw instrumentation. Four (14.3% stand-alone levels experienced cage subsidence. Pain (VAS and disability (ODI improved markedly postoperatively and were maintained through 24 months. Segmental lordosis increased significantly and fusion was achieved in 93% of levels. In this series, isolated axial low back pain arising from degenerative disc disease was treated with minimally-invasive lateral interbody fusion in significant radiographic and clinical improvements, which were maintained through 24 months.

  13. The role of nutritional supplements in the prevention and treatment of resistance exercise-induced skeletal muscle injury.

    2007-01-01

    The topic of exercise-induced skeletal muscle injury has received considerable attention in recent years. Likewise, strategies to minimise the injury resulting from heavy resistance exercise have been studied. Over the past 15 years, several investigations have been performed focused on the role of nutritional supplements to attenuate signs and symptoms of muscle injury. Of these, some have reported favourable results, while many others have reported no benefit of the selected nutrient. Despite these mixed findings, recommendations for the use of nutritional supplements for the purposes of attenuating muscle injury are rampant within the popular fitness media and athletic world, largely without scientific support. Those nutrients include the antioxidant vitamin C (ascorbic acid) and vitamin E (tocopherol), N-acetyl-cysteine, flavonoids, L-carnitine, astaxanthin, beta-hydroxy-beta-methylbutyrate, creatine monohydrate, essential fatty acids, branched-chain amino acids, bromelain, proteins and carbohydrates. A discussion of all published peer-reviewed articles in reference to these nutrients and their impact on resistance exercise-induced skeletal muscle injury is presented, in addition to a brief view into the potential mechanism of action for each nutrient.Based on the current state of knowledge, the following conclusions can be made with regard to nutritional supplements and their role in attenuating signs and symptoms of skeletal muscle injury occurring as a consequence of heavy resistance exercise: (i) there appears to be a potential role for certain supplements (vitamin C, vitamin E, flavonoids, and L-carnitine); (ii) these supplements cannot effectively eliminate muscle injury, only attenuate certain signs and symptoms; (iii) it is presently unclear what the optimal dosage of these nutrients is (whether used alone or in combination); (iv) it is unclear what the optimal pretreatment period is; and (v) the effectiveness is largely specific to non

    1993-01-01

    Studies of the dietary practices of athletes report that nutritional supplements are commonly used. Supplementation practices vary between sports and individual athletes; however, there is evidence that at least some athletes use a large number of supplements concurrently, often in doses that are very high in comparison with normal dietary intakes. In exploring supplementation practices we propose a classification system separating the supplements into dietary supplements and nutritional erogogenic aids. The dietary supplement is characterised as a product which can be used to address physiological or nutritional issues arising in sport. It may provide a convenient or practical means of consuming special nutrient requirements for exercise, or it may be used to prevent/reverse nutritional deficiencies that commonly occur among athletes. The basis of the dietary supplement is an understanding of nutritional requirements and physiological effects of exercise. When the supplement is used to successfully meet a physiological/nutritional goal arising in sport it may be demonstrated to improve sports performance. While there is some interest in refining the composition or formulation of some dietary supplements, the real interest belongs to the use or application of the supplement; i.e. educating athletes to understand and achieve their nutritional needs in a specific sports situation. The sports drink (carbohydrate-electrolyte replacement drink) is a well known example of a dietary supplement. Scientific attitudes towards the sports drink have changed over the past 20 years. Initial caution that carbohydrate-electrolyte fluids compromise gastric emptying during exercise has now been shown to be unjustified. Numerous studies have shown that 5 to 10% solutions of glucose, glucose polymers (maltodextrins) and other simple sugars all have suitable gastric emptying characteristics for the delivery of fluid and moderate amounts of carbohydrate substrate.

    Objective: To evaluate the efficacy of axonal repair technique for treatment of peripheral nerve injury clinically.Methods: In 1998, the authors applied axonal repair technique to treat peripheral nerve injuries in 12 patients with 13 nerves. It consists of four steps, ie, stumps of the nerve being soaked in a modified Collins fluid, freezed,trimmed, and coapted with glue, making the injured nerve repaired at the axonal level.Results: The patients were followed up for an average of 13 months. Results showed that in 4 cases of first-stage contraiateral C7 transfer, regenerating axons reached to the sternoclavicular joint or axilla at 4 to 7 months, offering the timing for performing the second-stage contralateral C7 transfer. In 5 cases of accessory nerve transferred to the suprascapular nerve, the abduction of the shoulder was 40° on average. In the other 3 patients with four different nerves repaired, results were also satisfactory.Conclusions: This technique is promising in the treatment of peripheral nerve injury.

    Full Text Available ABSTRACT Objective: Analysis of the use of polyetheretherketone (PEEK cages for atlantoaxial facet realignment and distraction for treatment of basilar invagination by Goel technique. Method: Retrospective descriptive statistical analysis of the neurological status, pain, presence of subsidence and bone fusion with the use of PEEK cages in 8 atlantoaxial joints of 4 patients with basilar invagination. All patients were treated with atlantoaxial facet distraction and realignment and subsequent arthrodesis C1-C2 by the technique of Goel modified by the use of PEEK cage. Results: All patients showed improvement in Nurick neurological assessment scale and Visual Analogue Scale (VAS of pain. There were no cases of subsidence, migration, or damage to the vertebral artery during the insertion of the cage. All joints evolved with bone fusion, assessed by dynamic radiographs, and computed tomography. Two patients developed neuropathic pain in dermatome of C2 and one patient had unilateral vertebral artery injury during C2 instrumentation treated with insertion of pedicle screw to control the bleeding. Conclusion: The results of the treatment of basilar invagination by the Goel technique with the use of PEEK cages shown to be effective and safe although further studies are needed to confirm this use.

    This work aims at investigating the impact of treating breast cancer using different radiation therapy (RT) techniques--forwardly-planned intensity-modulated, f-IMRT, inversely-planned IMRT and dynamic conformal arc (DCART) RT--and their effects on the whole-breast irradiation and in the undesirable irradiation of the surrounding healthy tissues. Two algorithms of iPlan BrainLAB treatment planning system were compared: Pencil Beam Convolution (PBC) and commercial Monte Carlo (iMC). Seven left-sided breast patients submitted to breast-conserving surgery were enrolled in the study. For each patient, four RT techniques--f-IMRT, IMRT using 2-fields and 5-fields (IMRT2 and IMRT5, respectively) and DCART - were applied. The dose distributions in the planned target volume (PTV) and the dose to the organs at risk (OAR) were compared analyzing dose-volume histograms; further statistical analysis was performed using IBM SPSS v20 software. For PBC, all techniques provided adequate coverage of the PTV. However, statistically significant dose differences were observed between the techniques, in the PTV, OAR and also in the pattern of dose distribution spreading into normal tissues. IMRT5 and DCART spread low doses into greater volumes of normal tissue, right breast, right lung and heart than tangential techniques. However, IMRT5 plans improved distributions for the PTV, exhibiting better conformity and homogeneity in target and reduced high dose percentages in ipsilateral OAR. DCART did not present advantages over any of the techniques investigated. Differences were also found comparing the calculation algorithms: PBC estimated higher doses for the PTV, ipsilateral lung and heart than the iMC algorithm predicted.

    Full Text Available Abstract Background The purpose of this proof-of-principle study was to test the ability of an intensity-modulated radiotherapy (IMRT technique to reduce the radiation dose to the heart plus the left ventricle and a coronary artery. Radiation-induced heart disease might be a serious complication in long-term cancer survivors. Methods Planning CT scans from 6 female patients were available. They were part of a previous study of mediastinal IMRT for target volumes used in lymphoma treatment that included 8 patients and represent all cases where the left anterior descending coronary artery (LAD could be contoured. We compared 6 MV AP/PA opposed fields to a 3D conformal 4-field technique and an optimised 7-field step-and-shoot IMRT technique and evaluated DVH's for several structures. The planning system was BrainSCAN 5.21 (BrainLAB, Heimstetten, Germany. Results IMRT maintained target volume coverage but resulted in better dose reduction to the heart, left ventricle and LAD than the other techniques. Selective dose reduction could be accomplished, although not to the degree initially attempted. The median LAD dose was approximately 50% lower with IMRT. In 5 out of 6 patients, IMRT was the best technique with regard to heart sparing. Conclusion IMRT techniques are able to reduce the radiation dose to the heart. In addition to dose reduction to whole heart, individualised dose distributions can be created, which spare, e.g., one ventricle plus one of the coronary arteries. Certain patients with well-defined vessel pathology might profit from an approach of general heart sparing with further selective dose reduction, accounting for the individual aspects of pre-existing damage.

    This study investigates the effects of feeding diet based on untreated (UT) or ensiled alkali-treated (ET) barley straw with either urea or casein supplementation, on feed intake, digestibility, ruminal pH, water intake and faecal and urinary characteristics. Four sheep fitted with ruminal cannulas were used in a 4 × 4 Latin square design with a 2 × 2 factorial arrangement of treatments. Barley straw was treated by the dry (spraying) method in pH adjusted of hydrogen peroxide (pH 11.5), ensiled for 6 weeks and included at 65% of the diet dry matter (DM). The results showed that straw pH reduced from 11.58 to 8.60 after 6 weeks of ensilage. The ET diet increased average DM digestibility and intake by 19% and 43% respectively. Total water intake was similar across treatments, while the water/DM intake ratio was 23% higher with the UT diet than with the ET one. Ruminal (6.73 vs. 6.84) and faecal (8.67 vs. 9.05) pH decreased but urinary pH (6.14 vs. 8.13) increased as a result of feeding animals on the ET diet compared with the UT diet. Compared with the UT diet, the ET one decreased faecal fibre (12%), moisture (32%) and water holding capacity, while it increased faecal ash (10%) and density (20%). The volume of urine excreted by the sheep fed with the ET diet increased by 67%, but their urine specific gravity (SG) decreased. No significant effects were observed for the dietary N supplementation and interactions between straw type × N supplementation with regard to any of the measured characteristics except for DM intake, which reduced due to the casein supplementation in the ET diet. These results indicate that the alkali treatment and ensilage of barley straw increased digestibility, intake, faecal consistency and urinary pH and dilution but decreased straw alkalinity as well as ruminal and faecal pH. © 2013 Blackwell Verlag GmbH.

    Management of oral leukoplakia-a potentially malignant disorder-is currently not evidence-based. Of the few randomized trials that have been reported, most have negative data. Therefore, a multi-centre, randomized, double-blind controlled trial (RCT) was undertaken to evaluate the use of low-dose beta-carotene combined with vitamin C supplements for the treatment and to prevent malignant transformation of oral leukoplakia. 46 Japanese participants with oral leukoplakia were allocated randomly either to an experimental arm (10 mg day(-1) of beta-carotene and 500 mg day(-1) of vitamin C) or placebo arm (50 mg day(-1) of vitamin C). Current or ex-smokers within 3 months of cessation were excluded. The supplements were continued over a period of 1 year. The primary endpoint was clinical remission at 1-year and the likelihood of malignant transformation during a 5-year follow-up period as a secondary endpoint. The overall clinical response rate in the experimental arm was 17.4% (4/23) and 4.3% (1/23) in the placebo arm (p = 0.346). During the median 60-month follow-up period, two subjects in the experimental arm and three in the control arm developed oral cancer. Under the intention-to-treat principle, relative risk by supplementing with beta-carotene and vitamin C was 0.77 (95%CI: 0.28-1.89) (p = 0.580) by the Cox proportional hazards model. No unfavorable side-effects were noted. Beta-carotene (10 mg day(-1) ) and vitamin C were neither effective for clinical remission, nor for protection against the development of cancer. Data from this RCT does not support the hypothesis that chemoprevention with this treatment is effective for oral leukoplakia.

    2014-07-01

    Untreated growing patients with congenital scoliosis and fused ribs will develop finally thoracic insufficiency syndrome. The technique of expansion thoracoplasty with implantation of a vertical expandable prosthetic titanium rib (VEPTR) was introduced initially to treat these children. This article attempts to provide an overview of the surgical technique of opening-wedge thoracostomy and VEPTR instrumentation in children with congenital thoracic scoliosis and fused ribs. Our modification of the surgical approach using a posterior midline incision rather than the modified thoracotomy incision initially described could potentially help to diminish wound dehiscence and secondary infection, while preserving a more acceptable esthetic appearance of the back. Vertical expandable prosthetic titanium rib-based treatments should be undertaken only with a good knowledge of its numerous specific complications. Every aspect of the treatment should be oriented to minimize these complications. At the same time it should be kept in mind that the ultimate step of this long-term fusionless treatment strategy will be a technically demanding spine fusion.

    The management of tracheobronchomalacia is a very challenging problem with few treatment options. This study aims to evaluate the outcomes of a novel surgical treatment for membranous tracheobronchomalacia. A consecutive series of patients with tracheobronchomalacia were treated with two to three holmium laser scarring surgeries of the hyperdynamic tracheal and bronchial walls for the purpose of stiffening them through fibrosis. Patients filled out a Dyspnea Index questionnaire before and after treatment. Ten patients were treated for their tracheobronchomalacia with a mean age of 54 years. Symptoms included severe dyspnea, dry cough, recurrent pulmonary infections, and respiratory failure. Fifty percent of patients presented with wheezing refractory to traditional treatment. Tracheobronchomalacia was associated with gastroesophageal reflux disease (n = 8), obstructive sleep apnea (n = 5), and tracheal stenosis (n = 3). Only 50 % of patients presented with morbid obesity. All cases showed significant improvement of their respiratory symptoms with a mean postoperative difference of 22.3 out of a maximum impairment score of 40 (P < 0.01) on the Dyspnea Index. The mean number of procedures was 2.3 per patient with the average laser energy delivered per procedure of 1600 J. Laser tracheobronchoplasty is a safe, easy to adopt, and effective technique for the treatment of membranous tracheobronchomalacia. It presents a simple alternative to the commonly used procedures like endoluminal stenting and open tracheobronchoplasty.

    Current management options for infertility, including hormone therapy, intrauterine insemination, and in vitro fertilization, tend to be expensive, are not necessarily covered by insurance, and carry different levels of short-term and long-term health risks. Many of the issues that contribute to infertility can be traced to scar tissue, fascial restriction, and lymphatic congestion in the pelvic region. Manual therapy techniques exist to release fascial restrictions, to mobilize tight ligaments, and to drain congested lymphatics, all of which can be applied to the reproductive system. In this case series, 10 infertile women were treated with 1 to 6 sessions of manual therapy applied to the pelvic region. Techniques included muscle energy, lymphatic drainage, and visceral manipulation. Six of the 10 women conceived within 3 months of the last treatment session, and all 6 of those women delivered at full term.

    Due to its retroperitoneal location, the pancreas has historically been a mysterious organ that is difficult to examine and which complicates treatment. The discovery of anesthesia and asepsis in the mid-19th century allowed laparotomic diagnosis, which was previously only possible at autopsy. The expectations of surgery were improved by the detection of blood groups, vitamin K synthesis, and the development of intensive care units. In addition, high levels of presurgical diagnosis and an unquestionable improvement of its results were enabled by advances in laboratory methods (serum quantification of amylase and lipase, tumoral markers, genetics, and techniques for measuring exocrine pancreatic function), imaging and endoscopic modalities, and fine tuning of surgical techniques. In this article, we review the history of the main milestones that have allowed progress in all these aspects. Copyright © 2014 Elsevier España, S.L.U. and AEEH y AEG. All rights reserved.

    Full Text Available Gingival recession related to periodontal disease or developmental problems can result in root sensitivity, root caries, and esthetically unacceptable root exposures. In the past, multiple surgical procedures have been proposed to obtain root coverage on exposed buccal root surfaces. There has been great interest in the treatment of gingival recession defects, especially with subepithelial connective-tissue grafting (SCTG. Recent advances have focused on SCTG by the tunnel technique. This article highlights the esthetic results obtained by adopting a modification of the tunnel technique using a single vertical incision along with autologous SCTG in the management of multiple adjacent Miller Class-II gingival recessions. A single vertical incision was used along with tunnel preparation for the facile placement of SCTG into the prepared tunnel. After 6 months of follow-up, the clinical condition was stable with satisfactory root coverage outcome. An excellent esthetical outcome was achieved and the patient was satisfied with the result.

    Parkinson’s disease (PD) affects at least 10 million people worldwide. It is a neurodegenerative disease, which is currently diagnosed by neurological examination. No neuroimaging investigation or blood biomarker is available to aid diagnosis and prognosis. Most effort toward diagnosis using magnetic resonance (MR) has been focused on the use of structural/anatomical neuroimaging and diffusion tensor imaging (DTI). However, deep brain stimulation, a current strategy for treating PD, is guided by MR imaging (MRI). For clinical prognosis, diagnosis, and follow-up investigations, blood oxygen level-dependent MRI, DTI, spectroscopy, and transcranial magnetic stimulation have been used. These techniques represent the state of the art in the last 5 years. Here, we focus on MR techniques for the diagnosis and treatment of Parkinson’s disease. PMID:26191037

    The impact of ambient concentrations in the vicinity of a plant can only be assessed if the emission rate is known. In this study, based on measurements of ambient H2S concentrations and meteorological parameters, the a priori unknown emission rates of a tannery wastewater treatment plant are calculated by an inverse dispersion technique. The calculations are determined using the Gaussian Austrian regulatory dispersion model. Following this method, emission data can be obtained, though only for a measurement station that is positioned such that the wind direction at the measurement station is leeward of the plant. Using the inverse transform sampling, which is a Monte Carlo technique, the dataset can also be completed for those wind directions for which no ambient concentration measurements are available. For the model validation, the measured ambient concentrations are compared with the calculated ambient concentrations obtained from the synthetic emission data of the Monte Carlo model. The cumulative frequency distribution of this new dataset agrees well with the empirical data. This inverse transform sampling method is thus a useful supplement for calculating emission rates using the inverse dispersion technique.

    Sexual maturation of Anastrepha fraterculus is a long process. Methoprene (a mimic of juvenile hormone) considerably reduces the time for sexual maturation in males. However, in other Anastrepha species, this effect depends on protein intake at the adult stage. Here, we evaluated the mating competitiveness of sterile laboratory males and females that were treated with methoprene (either the pupal or adult stage) and were kept under different regimes of adult food, which varied in the protein source and the sugar:protein ratio. Experiments were carried out under semi-natural conditions, where laboratory flies competed over copulations with sexually mature wild flies. Sterile, methoprene-treated males that reached sexual maturity earlier (six days old), displayed the same lekking behaviour, attractiveness to females and mating competitiveness as mature wild males. This effect depended on protein intake. Diets containing sugar and hydrolyzed yeast allowed sterile males to compete with wild males (even at a low concentration of protein), while brewer´s yeast failed to do so even at a higher concentration. Sugar only fed males were unable to achieve significant numbers of copulations. Methoprene did not increase the readiness to mate of six-day-old sterile females. Long pre-copulatory periods create an additional cost to the management of fruit fly pests through the sterile insect technique (SIT). Our findings suggest that methoprene treatment will increase SIT effectiveness against A. fraterculus when coupled with a diet fortified with protein. Additionally, methoprene acts as a physiological sexing method, allowing the release of mature males and immature females and hence increasing SIT efficiency.

    To determine if lumbar synovial cyst rupture in symptomatic patients results in improved clinical outcome when using direct tandem and/or coaxial percutaneous CT guided techniques. 20 patients with unilateral lower extremity radiculopathy and/or low back pain underwent CT guided percutaneous treatment for their symptomatic lumbar synovial cysts. Cysts were identified with the use of a low osmolar non-ionic contrast agent via facet joint injection or through direct injection. Cyst rupture, using a direct tandem and/or coaxial technique, was attempted in all patients using an 18 gauge guide needle and a 22 gauge insert needle. Following attempted cyst aspiration, cyst rupture was performed using 1-3 mL of a mixture of methylprednisolone (2 mL, 80 mg) and bupivacaine (3 mL, 0.5%). All patients were followed-up in clinic for a minimum of 6 months after their procedures and up to a maximum of 24 months. 11 patients were male and nine were female, with an average age of 65.6 years. 17 patients presented with severe unilateral lower extremity radiculopathy and three patients were experiencing low back pain. One of the patients had two synovial cysts, and therefore a total of 21 lumbar synovial cysts were treated in this group of patients. Direct cyst puncture was achieved using a tandem technique in nine patients, a coaxial interlaminar approach in seven patients, a coaxial transforaminal approach in two patients, and a coaxial trans-facet approach in three patients. Cyst rupture was documented in all cases, as evidenced by CT confirmation of cyst decompression and contrast agent extravasation into the epidural space. The mean surveillance period in these patients was 18 months. Six patients experienced their usual radicular pain within 2 months of their treatment. Four of these patients were re-treated for recurrent smaller cysts. These patients have not had a recurrence at 24 months of follow up. Two of these six patients elected to undergo open

    Full Text Available Urethral stricture is a common condition that can lead to serious complications such as urinary infections and renal insufficiency secondary to urinary retention. Treatment options include catheterization, urethroplasty, endoscopic internal urethrotomy, and dilation. Optical internal urethrotomy offers faster recovery, minimal scarring, and less risk of infection, although recurrence is possible. However, technical difficulties associated with poor visualization of the stenosis or of the urethral lumen may increase procedural time and substantially increase the failure rates of internal urethrotomy. In this report we describe a technique for urethral catheterization via a suprapubic, percutaneous approach through the urinary bladder in order to facilitate endoscopic internal urethrotomy.

    Full Text Available From January 2001 to December 2003, 52 patients, 31 females and 21 males, aged between 19 and 78 years, underwent iontophoresis; they all had acute lumbar ischialgia or hiparthrosis; each cycle consisted of 4 consecutive applications in successive days. The 88% of patients (n = 46 had a positive outcome; in 12% (n = 6, pain with characteristics similar to that before treatment arouse again. No patient showed a worsening or side effects on long term. The validity and the advantages of the technique indicate that the iontophoresis is a useful non-invasive and non-traumatic therapeutic presidium, which allows direct drug use in painful area.

    This article reports how continuous quality improvement (CQI) techniques were applied to physician care of patients with hypertension. A physician task force at an ambulatory care center used CQI methods to address the needs of two important "customer" groups: (1) third party payors and (2) patients with hypertension. Treatment standards were defined that can also serve as a customer-oriented product description. The task force found patients' blood pressures generally well controlled. Future studies will focus on appointment making, giving advice, and the doctor's examination as subprocesses that strongly influence patient satisfaction.

    Background Treatment of rapidly progressing scoliosis in young children is a challenge for spine surgeons. Some surgeons had begun to use dual growing rod technique for treatment of rapidly progressing scoliosis in young children and had achieved acceptable results. The aim of this study was to determine the primary results and complications of this new technique in China. Methods Eleven children suffering from rapidly progressing scoliosis were treated with dual growing rod technique between November 2004 and March 2009 at Peking Union Medical College Hospital (PUMCH). There were 10 females and 1 male in the group with Risser sign of 0 grade. The mean age at initial surgery was 6.1 years (range, 2.1-10.9 years). Ten patients were diagnosed as congenital scoliosis and 1 patient neuromuscular scoliosis. All the patients had 1-4 lengthening procedures (mean, 1.8 procedures) after the initial surgeries. The radiographic results of all the patients were investigated. Results The coronal Cobb angle of scoliosis improved from (67.64±11.43)° to (34.64±8.26)° after initial surgery with the correction rate observed at (47.15±16.48)%. The coronal trunk shift improved from (2.00±1.73) cm to (1.49±1.31) cm after initial surgery. The T1-S1 height increased from (25.47±6.16) cm to (28.84±5.69) cm after initial surgery. The coronal Cobb angle of scoliosis was (36.82±11.76)° and the coronal trunk shift was (1.11 ±1.29) cm after the most recent lengthening procedure with the most recent correction rate observed at (44.73±19.43)%. The T1-S1 height was (31.29±4.50) cm after the most recent lengthening procedure with an average T1-S1 length increase of 1.6 (range, 1.0-2.7) cm per year during the lengthening period. The sagittal balance was maintained. Five of the total patients (45.5%) had complications including: hook displacement, pedical screw loosening, and broken rod. We performed revision surgeries with simultaneous lengthening procedures in all 5 cases with

    The vascular dynamics of a shape memory polymer foam aneurysm treatment technique are assessed through the simulated treatment of a generic basilar aneurysm using coupled fluid dynamics and heat transfer calculations. The shape memory polymer foam, which expands to fill the aneurysm when heated, is modeled at three discrete stages of the treatment procedure. To estimate an upper bound for the maximum amount of thermal damage due to foam heating, a steady velocity is specified through the basilar artery, corresponding to a minimum physiological flow velocity over a cardiac cycle. During expansion, the foam alters the flow patterns within the aneurysm by shielding the aneurysm dome from a confined jet that issues from the basilar artery. The time scales for thermal damage to the artery walls and surrounding blood flow are computed from the temperature field. The flow through the post-treatment bifurcation is comprised of two counter-rotating vortex tubes that are located beneath the aneurysm neck and extend downstream into the outlet arteries. Beneath the aneurysm neck, a marked increase in the wall shear stress is observed due to the close proximity of the counter-rotating vortex tubes to the artery wall.

    2011-03-15

    Purpose: The fraction duration of robotic radiosurgery treatments can be reduced by generating more time-efficient treatment plans with a reduced number of node positions, beams, and monitor units (MUs). Node positions are preprogramed locations where the robot can position the focal spot of the x-ray beam. As the time needed for the robot to travel between node positions takes up a large part of the treatment time, the aim of this study was to develop and evaluate a node reduction technique in order to reduce the treatment time per fraction for robotic radiosurgery. Methods: Node reduction was integrated into the inverse planning algorithm, developed in-house for the robotic radiosurgery modality. It involved repeated inverse optimization, each iteration excluding low-contribution node positions from the planning and resampling new candidate beams from the remaining node positions. Node reduction was performed until the exclusion of a single node position caused a constraint violation, after which the shortest treatment plan was selected retrospectively. Treatment plans were generated with and without node reduction for two lung cases of different complexity, one oropharyngeal case and one prostate case. Plan quality was assessed using the number of node positions, beams and MUs, and the estimated treatment time per fraction. All treatment plans had to fulfill all clinical dose constraints. Extra constraints were added to maintain the low-dose conformality and restrict skin doses during node reduction. Results: Node reduction resulted in 12 residual node positions, on average (reduction by 77%), at the cost of an increase in the number of beams and total MUs of 28% and 9%, respectively. Overall fraction durations (excluding patient setup) were shortened by 25% (range of 18%-40%), on average. Dose distributions changed only little and dose in low-dose regions was effectively restricted by the additional constraints. Conclusions: The fraction duration of robotic

    Iliotibial band friction syndrome is an overuse injury caused by repetitive friction of the iliotibial band across the lateral femoral epicondyle. It has been reported to afflict long-distance runners, cyclists and military personnel. Initial treatments include rest, anti-inflammatory medication, modalities (ice or heat), stretching, physical therapy, and possibly a corticosteroid injection. If the conservative treatment is unsuccessful, surgery has been advocated. This report describes a new surgical technique to release the pressure on the lateral femoral epicondyle in a patient who failed the nonoperative efforts. The surgery was performed with the knee held in 30 degrees of flexion and consisted of multiple 2 mm long incisions across the fiber of the iliotibial band covering the lateral femoral epicondyle. There were six incisions, each of which was 4 mm apart. The incisions were spontaneously enlarged and changed to several punctured wounds (mesh appearance) by the tension of iliotibial band, resulted in relaxing the tight iliotibial band over the lateral femoral epicondyle. At the final follow-up 2 years after surgery the patient was pain free and could resume his previous occupational activities. The surgical result of the present technique is encouraging.

    Robert's uterus is a unique malformation, described as a septate uterus with a non-communicating hemicavity, consisting of a blind uterine horn usually with unilateral hematometra, a contralateral unicornuate uterine cavity and a normally shaped external uterine fundus. The main symptom in affected young women is pelvic pain that becomes intensified near menses. We describe the case of a 22-year-old woman who was referred for diagnostic assessment and treatment of a congenital uterine anomaly. We used three-dimensional sonohysterography with volume-contrast imaging, HDLive rendering mode and automatic volume calculation (SonoHysteroAVC) for the diagnosis, surgical planning and postoperative evaluation. These imaging techniques provided a complete understanding of the internal and external uterine structures, enabling us to perform a minimally invasive hysteroscopic metroplasty, guided by transrectal ultrasound, and therefore avoiding the need for laparotomy/laparoscopy. The outcome of treatment was considered satisfactory; menstruation ceased to be painful and, after two hysteroscopic procedures, the communicating 0.3-cm(3) hemicavity was visualized as a 3.6-cm(3) normalized uterine cavity using the same imaging techniques. The findings of this case report raise questions about the embryological origin of Robert's uterus, the suitability of current classification systems, and the role of more invasive approaches (laparoscopy/laparotomy) and surgical procedures (horn resection/endometrectomy) that do not aim to improve uterine cavity shape and volume in women with this condition.

    To reduce the morbidity of traditional quadricepsplasty for the treatment of severe arthrofibrosis of the knee, we instituted a treatment regimen consisting of an initial extra-articular mini-invasive quadricepsplasty and subsequent intra-articular arthroscopic lysis of adhesions during the same anesthesia session. The purpose of the present study was to determine the results of this technique. From 1998 to 2001, twenty-two patients with severely arthrofibrotic knees were managed with this operative technique. The mean age of the patients at the time of the operation was thirty-seven years. After a mean duration of follow-up of forty-four months (minimum, twenty-four months), all patients were evaluated according to the criteria of Judet and The Hospital for Special Surgery knee-rating system. The average maximum degree of flexion increased from 27 degrees preoperatively to 115 degrees at the time of the most recent follow-up (p < 0.001). According to the criteria of Judet, the result was excellent for sixteen knees, good for five, and fair for one. The average Hospital for Special Surgery knee score improved from 74 points preoperatively to 94 points at the time of the most recent follow-up (p < 0.001). A superficial wound infection occurred in one patient. Only one patient had a persistent 15 degrees extension lag. This mini-invasive operation for the severely arthrofibrotic knee can be used to increase the range of motion and enhance functional outcome.

    This study compared lateral photon/electron plan (3DCRT), intensity modulated radiation therapy (IMRT) plan, and high dose rate (HDR) brachytherapy plan for total scalp irradiation. The techniques were planned on a patient with squamous cell carcinoma of the scalp for a prescribed dose of 60 Gy. Conformity indexes and dose volume histograms were used for the comparison. Clinical target volume coverage factors for 3DCRT, IMRT, and HDR were 0.976, 0.998, and 0.967, and Conformation Numbers were 0.532, 0.713, and 0.761, respectively. The dose gradient across the target was 59-136%, 91-129%, and 58-242% for 3DCRT, IMRT, and HDR techniques, respectively. The 3DCRT and IMRT techniques produced low optical structure doses. 3DCRT produced hotspots in the brain, while IMRT produced brain sparing. HDR produced the highest integral doses to the brain and optical structures. IMRT provided the best target dose homogeneity and coverage, and delivered clinically acceptable doses to normal structures. HDR produced the most conformal plan, but the total dose delivered is limited by doses to the brain and eyes. HDR is a clinically feasible alternative for less extensive lesions, lower prescription doses, and for patients who cannot lie on the treatment table.

    Primary pancreatic hydatid cysts are rare and its percutaneous treatment and catheterization technique has, to the best of our knowledge, not been published in literature. A 33-year-old male patient who presented with abdominal pain was evaluated by ultrasonography (US) and computed tomography examinations. Both examinations revealed a cyst in the neck of the pancreas. After the administration of albendazole chemoprophylaxis, the patient underwent diagnostic puncture showing high pressure spring water which harbored the scoleces and was treated percutaneously by the catheterization technique. In this technique, first the cyst was punctured, the fluid content aspirated, the radiocontrast material injected to see possible fistulisation, and then re-aspirated. The 20% hypertonic saline solution was injected and re-aspiration was performed to the best of our abilities, followed by the insertion of a catheter for drainage of the remaining non-aspiratable fluid content. At follow-up examination, the cyst was not visible on US after 6 months. There was no evidence of cyst recurrence or dissemination after 18 months at serologic and imaging follow-up.

    Purpose of this work is to present the role of in-house manufactured MAGAT gel for treatment verification in small field dosimetric techniques such as Gammaknife (GK) and intensity-modulated radiation therapy (IMRT). Magnetic resonance imaging (MRI) is one of the most extensively used imaging technique for polymer gel dosimetry hence we used this method for gel evaluation. Different MR scanners and MRI sequences were used in this study for obtaining calibration plot between R2 and absorbed dose. An experimental plan was created for Gammaknife and IMRT. The prepared gel was filled in spherical glass phantom and in-house designed human head shape phantom for verification purpose. We used 8 TE values for all the imaging sequences for two reasons. Firstly it is sufficient enough to give good signal to noise ratio. Second considering the enormous scanning time involved in multiple spin echo sequence. MATLAB based in-house programs were used for R2 estimation and dose comparison. The isodose comparison with MAGAT gel showed reasonable agreement for both Gammaknife and IMRT techniques.

    Objective:To explore the clinical efficacy of transforaminal endoscopic discectomy using TESSYS technique in the treatment of lumbar disc herniation (LDH).Methods:A total of 60 patients with LDH who were admitted in our hospital from June, 2014 to February, 2016 were included in the study and randomized into the study group and the control group. The patients in the study group were performed with transforaminal endoscopic discectomy using TESSYS technique, while the patients in the control group were performed with the vertebral lamina fenestration. VAS was used to evaluate the pain relieving before operation, 1 d, 1 month, 3 months, and 6 months after operation. The fasting elbow venous blood before operation, 3, 6, 12, 24, and 48 h after operation was collected. The immune scatter turbidity was used to detect hs-CRP. ELISA was used to detect IL-6.Results:The difference of VAS scores before operation between the two groups was not statistically significant (P>0.05). With the time extending after operation, VAS score was significantly reduced (P0.05). The difference of hs-CRP and IL-6 before operation between the two groups was not statistically significant (P>0.05). The levels of hs-CRP and IL-6 after operation at each timing point in the study group were significantly superior to those in the control group (P<0.05). Conclusions:Transforaminal endoscopic discectomy using TESSYS technique in the treatment of LDH has advantages of small trauma, less stress reaction, and rapid postoperative recovery; therefore, it deserves to be widely recommended in the clinic.

    Full Text Available Varicocele repair is mainly indicated in young adult patients with clinical palpable varicocele and abnormal semen parameters. Varicocele treatment is associated with a significant improvement in sperm concentration, motility, morphology, and pregnancy rate. Antegrade scrotal sclerotherapy (ASS represented one of the main alternatives to the traditional inguinal or suprainguinal surgical ligation. This article reviews the use of ASS for varicocele treatment. We provide a brief overview of the history of the procedure and present our methods used in ASS. In addition, we review complication and success of ASS, including our own retrospective data of treating 674 patients over the last 17 years. Herein, we analyzed step by step the ASS technique and described our results with an original modified technique with a long follow-up. Between December 1997 and December 2014, we performed 674 ASS. Mean operative time was 14 min (range 9 to 50 min. No significant intraoperative complications were reported. Within 90 days from the procedure, postoperative complications were recorded in overall 49 (7.2% patients. No major complications were recorded. A persistent/recurrent varicocele was detected in 40 (5.9% cases. In 32/40 (80% cases, patients showed preoperative grade III varicoceles. In patients with a low sperm number before surgery, sperm count improved from 13 × 10 6 to 21 × 10 6 ml−1 (P < 0.001. The median value of the percentage of progressive motile forms at 1 h improved from 25% to 45% (P < 0.001. Percentage of normal forms increased from 17% before surgery to 35% 1 year after the procedure (P < 0.001. In the subgroup of the 168 infertile patients, 52 (31% fathered offspring at a 12-month-minimum follow-up. Therefore, ASS is an effective minimal invasive treatment for varicocele with low recurrence/persistence rate.

    The correct management, with the classic techniques, of the thoracic deformity in Poland's syndrome is difficult, with often insatisfactory results. The current surgical treatment involves the use of prothetic material and/or different flaps with their own complications and scares. The experience of our team with fat grafting (we named lipomodeling) in breast reconstruction helped us to propose the correction of the thoracic and mammary deformity by repeated fat transfer sessions. Fat grafting is commonly used in our team since 1998 in various indication of breast surgery. We reviewed retrospectively our ten first cases of thoracic deformity in Poland's syndrome treated with only fat grafting. Patients had repeated procedures until obtaining a satisfactory result. The fat was harvested from the thigh, buttocks, and abdomen. There were young patients with a mean age of 16years old (from 12 to 24). The mean follow-up was 51months. An average of 2.9 procedures (1 to 5) with 255cm(3) of fat injection at each procedure was needed to obtain symetry. Hundred percent of the patients were satisfied. No complication was noted. As reported, the reconstruction of the thoracic deformity and the mammary shape can be obtained by fat grafting. The absence of a flap donor site sequelae and the absence an implant allow this technique to be simple, reproductible, and without great complication. These criteria match well the surgical management of this deformity, which is mainly aesthetic. Moreover, the secondary benefit of liposuction of disgracious steatomery helps the acceptance of the procedure. Therefore in our hands, fat grafting to the breast (lipomodeling) is now our first choice treatment in thoracic Poland syndrome deformity. Given the rarity of this syndrome, we recommend a treatment by an operator who makes the learning curve of lipomodeling, and who often deals with Poland syndrome.

    Full Text Available Purpose: This in vitro study compared the effect of five different techniques on the surface roughness of feldspathic porcelain. Materials and Methods: 100 feldspathic porcelain disk samples mounted in acrylic resin blocks were divided into five groups (n=20 according to type of surface treatment: I, hydrofluoric acid (HFA; II, Deglazed surface porcelain treated with Neodymium:yttrium- aluminum-garnet (Nd:YAG laser; III, Deglazed porcelain surface treated with Erbium:yttrium-aluminum-garnet (Er:YAG laser; IV, Glazed porcelain surface treated with Neodymium:yttrium-aluminum-garnet (Nd:YAG laser, V; Glazed porcelain surface treated with Erbium:yttrium-aluminum-garnet (Er:YAG laser. The surface roughness of porcelain was measured with a noncontact optical profilometer. For each porcelain sample, two readings were taken across the sample, before porcelain surface treatment (T1 and after porcelain surface treatment (T2. The roughness parameter analyzed was the average roughness (Ra. Statistical analysis was performed using Kolmogorov–Smirnov and Wilcoxon signed rank test. Results: Mean Ra values for each group were as follows: I, 12.64±073; II, 11.91±0.74; III, 11.76±0.59; IV, 3.82 ±0.65; V, 2.77±0.57. For all porcelain groups, the lowest Ra values were observed in Group V. The highest Ra values were observed for Group I, with a significant difference with the other groups. Kolmogorov–Smirnov showed significant differences among groups (p<0.001. Conclusion: Surface treatment of porcelain with HFA resulted in significantly higher Ra than laser groups. Both Er:YAG laser or Nd:YAG laser on the deglaze porcelain surface can be recommended as viable treatment alternatives to acid etching.

    Context: Sportsmen’s groin, also called sports hernia and Gilmore groin, is one of the most frequent sports injuries in athletes and may place an athletic career at risk. It presents with acute or chronic groin pain exacerbated with physical activity. So far, there is little consensus regarding pathogenesis, diagnostic criteria, or treatment. There have been various attempts to explain the cause of the groin pain. The assumption is that a circumscribed weakness in the posterior wall of the inguinal canal, which leads to a localized bulge, induces a compression of the genital branch of the genitofemoral nerve, considered responsible for the symptoms. Methods: The authors developed an innovative open suture repair—the Minimal Repair technique—to fit the needs of professional athletes. With this technique, the circumscribed weakness of the posterior wall of the inguinal canal is repaired by an elastic suture; the compression on the nerve is abolished, and the cause of the pain is removed. In contrast with that of common open suture repairs, the defect of the posterior wall is not enlarged, the suture is nearly tension free, and the patient can return to full training and athletic activity within a shorter time. The outcome of patients undergoing operations with the Minimal Repair technique was compared with that of commonly used surgical procedures. Results: The following advantages of the Minimal Repair technique were found: no insertion of prosthetic mesh, no general anesthesia required, less traumatization, and lower risk of severe complications with equal or even faster convalescence. In 2009, a prospective cohort of 129 patients resumed training in 7 days and experienced complete pain relief in an average of 14 days. Professional athletes (67%) returned to full activity in 14 days (median). Conclusion: The Minimal Repair technique is an effective and safe way to treat sportsmen’s groin. PMID:23015941

    To demonstrate the dosimetric advantages and disadvantages of standard anteroposterior-posteroanterior (S-AP/PA{sub AAA}), inverse-planned AP/PA (IP-AP/PA) and volumetry-modulated arc (VMAT) radiotherapies in the treatment of children undergoing whole-lung irradiation. Each technique was evaluated by means of target coverage and normal tissue sparing, including data regarding low doses. A historical approach with and without tissue heterogeneity corrections is also demonstrated. Computed tomography (CT) scans of 10 children scanned from the neck to the reproductive organs were used. For each scan, 6 plans were created: (1) S-AP/PA{sub AAA} using the anisotropic analytical algorithm (AAA), (2) IP-AP/PA, (3) VMAT, (4) S-AP/PA{sub NONE} without heterogeneity corrections, (5) S-AP/PA{sub PB} using the Pencil-Beam algorithm and enforcing monitor units from technique 4, and (6) S-AP/PA{sub AAA[FM]} using AAA and forcing fixed monitor units. The first 3 plans compare modern methods and were evaluated based on target coverage and normal tissue sparing. Body maximum and lower body doses (50% and 30%) were also analyzed. Plans 4 to 6 provide a historic view on the progression of heterogeneity algorithms and elucidate what was actually delivered in the past. Averages of each comparison parameter were calculated for all techniques. The S-AP/PA{sub AAA} technique resulted in superior target coverage but had the highest maximum dose to every normal tissue structure. The IP-AP/PA technique provided the lowest dose to the esophagus, stomach, and lower body doses. VMAT excelled at body maximum dose and maximum doses to the heart, spine, and spleen, but resulted in the highest dose in the 30% body range. It was, however, superior to the S-AP/PA{sub AAA} approach in the 50% range. Each approach has strengths and weaknesses thus associated. Techniques may be selected on a case-by-case basis and by physician preference of target coverage vs normal tissue sparing.

    The soft drink production is an important sector in the manufacturing industry of Mexico. Water is the main source in the production of soft drinks. Wastewater from bottle washing is almost 50% of the total wastewater generated by this industry. In order to reduce the consumption of water, the water of the last bottle rinse can be reused in to the bottle pre-rinse and pre-washing cycles. This work presents the characterization of the final bottle washing rinse discharge and the treatability study for the most appropriate treatment system for recycling. Average characteristics of the final bottle wash rinse were as follows: Turbidity 40.46 NTU, COD 47.7 mg/L, TSS 56 mg/L, TS 693.6 mg/L, electrical conductivity 1,194 microS/cm. The results of the treatability tests showed that the final rinse water can be used in the pre-rinse and pre-washing after removing the totality of the suspended solids, 80% of the COD and 75% of the dissolved solids. This can be done using the following treatment systems: filtration-adsorption-reverse osmosis, or filtration-adsorption-ion exchange. The installation of these treatment techniques in the soft drink industry would decrease bottle washing water consumption by 50%.

    Exercise-related lower limb pain represents one of the most common presentations in sports medicine practice. This is usually caused by musculoskeletal overuse injuries but not uncommonly, a neuropathic cause may be suspected. A review of the literature revealed that peripheral neuropathic pain has never been documented in a child. It is possible that peripheral neuropathic pain of spinal origin may be more prevalent in children than previously recognized. This case report describes the presentation of a 12 year old tennis player with bilateral dorsal foot pain, who presented with positive findings of peripheral nerve sensitization which was successfully managed using neurodynamic treatment techniques. Differential diagnoses are considered and treatment and management described. A discussion of the clinical reasoning which led to the patient's diagnosis is included. This case report suggests the effectiveness of neurodynamic treatment in a child with bilateral foot pain who fulfilled published criteria for peripheral nerve sensitization. However, the single case methodology employed in this study limits generalization of its findings. Further studies are warranted to investigate the role of neurodynamics in musculoskeletal pain disorders in children.

    A multi-component polymer-coated molybdenum powder was chosen for selective laser sintering(SLS). The powder was prepared by coating polymer on Mo particles and frozen by grinding techniques. The laser sintering activities and sound densification response were obtained by optimizing the process parameters. The post-treatment process of SLS samples was developed, which was high temperature sintering Mo framework combined with Cu impregnation. Then, the Mo/Cu composites are gained. The microstructure evolution of post-treatment samples was investigated by scanning electron microscopy. Mo grains frequently string together. The microstructural characterization of Mo/Cu composites is homogeneous compound structure of adhesive phase Cu linked with Mo grains. There is little ellipsoidal Mo grains singly existing around Cu phase. Between Mo grains and Cu zone, there is a medium changing zone with width of 10-20 nm. Post-treatment mechanism is Mo framework sintering of solid phase and Cu impregnation of melting/solidification. The mechanical and thermal properties concluding tensile strength, elastic modulus, elongation and linear expansion of Mo/Cu composites were studied.

    To validate a new photogrammetric technique for quantifying eye surface area and using this to quantify the degree of improvement in symmetry in patients with oral-ocular synkinesis following Botulinum toxin injection. Feasibility study and retrospective outcomes analysis Ten patients' photographs were chosen from a photographic database. Their eye surface areas were measured independently by two raters using a graphics tablet. One rater repeated the procedure after 15 days. Bland-Altman plots were computed, ascertaining inter-rater and intra-rater variability. The eye surface areas of 19 patients were then derived from photographs taken before and after Botulinum toxin injections. Paired t-tests were used to analyse the significance of the difference in pre- and post-treatment symmetry. Ninety per cent of eye surface areas derived from the two raters were within a coefficient of variation of 0.1 (95% CI: 0.05-0.15). Similarly, 90% of eye surface areas derived from one rater had a coefficient of variation of 0.08 (95% CI: 0.04-0.12). Botulinum toxin significantly reduced synkinesis resulting from lip puckering, Mona Lisa smiling and Hollywood smiling (P<0.05). We have proposed a clinically valid tool for quantifying the effects of Botulinum toxin treatment for oral-ocular synkinesis. We recommend this method be used to monitor the response of such patients when receiving Botulinum toxin treatment.

    Conclusions: Although previously published short- and medium-term outcomes after percutaneous nucleoplasty appeared to be satisfactory, our long-term follow-up results show a significant decline in patient satisfaction over time. Percutaneous nucleoplasty is a safe and simple technique, with therapeutic effectiveness for the treatment of chronic LBP in selected patients. The technique is minimally invasive and can be used as part of a stepwise treatment plan for chronic LBP.

    2004-04-01

    Full Text Available Introduction : Pilonidal cysts occur predominantly in males. The lesion usually manifests itself clinically near the end of the second decade of life. The patients are often hirsute and frequently unaware of the presence of the sinus.Clinically, the lesion is asymptomatic until it becomes infected. The diagnosis is made on the basis of one or more small openings in the midline over the sacrococcygeal region approximately 3.5 to 5 cm posterior to the anal orifice. Infection may occur because of its proximity to the anal region. The symptoms of an abscess are classic. Trauma preceding the onset of symptoms has been reported. As this disease is seen in the young and active population and has a high prevalence, need for a surgical operation with decreased complications& duration of admission leading to faster return of the patient to daily life activities is felt. Methods& materials :In this sinple blind randomized clinical trial study, 60 young patients ( mean age of 21.9+/-3.09 years who refered to the surgical clinics of Baqiyatallah hospital and diagnosed as having pilonidal cysts requiring treatment were divided into two groups of 30 cases each, wherein Group One patients were operated upon using this new semi-closure technique and Group Two patients were operated upon using the classic open method. The patients were followed up till complete treatment and results were compared. Results :The effectiveness and advantages of semi closed method over the open method (p< 0.05 was observed.( post operative pain & bleeding , wound healing , change of dressing,time period of return to work and complete treatment. Conclusion : It is concluded that the semi closure excision method is better than the open method in all aspects for the treatment of pilonidal sinus.

    To demonstrate plan quality and provide a practical, systematic approach to the treatment planning technique for single isocenter cranial radiosurgery with volumetric modulated arc therapy (VMAT; RapidArc, Varian Medical systems, Palo Alto, CA). Fifteen patients with 1 or more brain metastases underwent single isocenter VMAT radiosurgery. All plans were normalized to deliver 100% of the prescription dose to 99%-100% of the target volume. All targets per plan were treated to the same dose. Plans were created with dose control tuning structures surrounding targets to maximize conformity and dose gradient. Plan quality was evaluated by calculation of conformity index (CI = 100% isodose volume/target volume) and homogeneity index (HI = maximum dose/prescription dose) scores for each target and a Paddick gradient index (GI = 50% isodose volume/100% isodose volume) score for each plan. The median number of targets per patient was 2 (range, 1-5). The median number of non-coplanar arcs utilized per plan was 2 (range, 1- 4). Single target plans were created with 1 or 2 non-coplanar arcs while multitarget plans utilized 2 to 4 non-coplanar arcs. Prescription doses ranged from 5-16 Gy in 1-5 fractions. The mean conformity index was 1.12 (± SD, 0.13) and the mean HI was 1.44 (± SD, 0.11) for all targets. The mean GI per plan was 3.34 (± SD, 0.42). We have outlined a practical approach to cranial radiosurgery treatment planning using the single isocenter VMAT platform. One or 2 arc single isocenter plans are often adequate for treatment of single targets, while 2-4 arcs may be more advantageous for multiple targets. Given the high plan quality and extreme clinical efficiency, this single isocenter VMAT approach will continue to become more prevalent for linac-based radiosurgical treatment of 1 or more intracranial targets and will likely replace multiple isocenter techniques.

    Endovascular treatment of the superficial femoral artery (SFA) is challenging in the presence of flush ostial occlusion. One of the main challenges is the availability of access sites for intervention. Contralateral retrograde femoral access followed by cross-over and antegrade intervention while commonly used, may not be feasible in cases of altered iliac anatomy (e.g. kissing iliac stents). Ipsilateral antegrade intervention using common femoral artery (CFA) access in these instances while possible is typically challenging due to inadequate working length of the CFA for interrogation of the SFA ostium, compounded by the lack of sheath stability. The “profunda anchor” technique uses a buddy wire in the profunda femoris artery (PFA) to stabilize the sheath and allow catheter manipulation for antegrade intervention at the level of the SFA ostium. The PFA is further used as a conduit for deployment of closure device to avoid interference with the treated SFA.

    This case report describes use of an intervention developed for patients with neurological diagnoses (neurodevelopmental treatment [NDT]) with a patient with musculoskeletal and pulmonary diagnoses. The patient was a 78-year-old woman referred to physical therapy for gait training, therapeutic exercises, and neuromuscular reeducation. Standing at her most upright, the patient initially had a 30 degrees kyphosis with extreme capital extension to bring her head to vertical. Shoulders were internally rotated, and the medial borders of the scapulae rested near the lateral border of the ribs and the scapular spines were at the level of C7. To address the postural impairments, I used NDT spinal and scapular mobilization techniques and strengthening in weight-bearing postures with modified bridging as preparation for gait training. At the end of the episode of care, the patient's upright posture had improved to 10 degrees kyphosis with head in neutral extension in both standing and walking.

    The objective of present study was to prepare and characterize Bilayer tablet formulation containing Metformin HCl in extended release matrix form and Pioglitazone HCl in immediate release form for the treatment of diabetes mellitus. Different formulations containing Metformin HCl were manufactured using 3(2) factorial designs. Influence of hydrophilic carrier, hydrophobic polymer on drug release was studied. Immediate release layer of Pioglitazone was optimized using different super disintegrants. All formulations were evaluated for percentage drug release. Optimization results indicated that release rate of Metformin is directly proportional to the levels of Eudragit S 100 and PEG 6000. Results confirmed that Bilayer tablet formulation containing extended release of Metformin HCl and immediate release of Pioglitazone HCl could be developed by using melt granulation technique.

    Merkel cell carcinoma, though rare, is one of the most aggressive tumors a dermatologist faces. More than a third of patients with this diagnosis die from the disease. Numerous researchers have attempted to identify clinical and pathologic predictors to guide prognosis, but their studies have produced inconsistent results. Because the incidence of Merkel cell carcinoma is low and it appears in patients of advanced age, prospective studies have not been done and no clear treatment algorithm has been developed. This review aims to provide an exhaustive, up-to-date account of Merkel cell carcinoma for the dermatologist. We describe prognostic factors and the imaging techniques that are most appropriate for evaluating disease spread. We also discuss current debates on treating Merkel cell carcinoma.

    Individuals infected with the human immunodeficiency virus (HIV-1) present with decreased CD4, a progressive increase in viral load, compromised cell immune defense, and hematologic alterations. The aim of this study was to assess the serum viral load, CD4, CD8, lymphocyte count and hematocrit at the beginning of antiretroviral therapy in individuals who were supplemented with N-acetylcysteine (NAC). Twenty volunteers participated in this double-blind, placebo-controlled 180-day study. Ten participants received 600 mg of NAC per day (NAC group) and the other ten serving as a control group received placebo. The above mentioned parameters were determined before treatment, and after 60, 120 and 180 days. In NAC-treated patients hematocrit remained stable and an increase in CD4 cell count took place earlier than that in the control group.

  13. A simulation benchmark to evaluate the performance of advanced control techniques in biological wastewater treatment plants

    2001-01-01

    Full Text Available Wastewater treatment plants (WWTP are complex systems that incorporate a large number of biological, physicochemical and biochemical processes. They are large and nonlinear systems subject to great disturbances in incoming loads. The primary goal of a WWTP is to reduce pollutants and the second goal is disturbance rejection, in order to obtain good effluent quality. Modeling and computer simulations are key tools in the achievement of these two goals. They are essential to describe, predict and control the complicated interactions of the processes. Numerous control techniques (algorithms and control strategies (structures have been suggested to regulate WWTP; however, it is difficult to make a discerning performance evaluation due to the nonuniformity of the simulated plants used. The main objective of this paper is to present a benchmark of an entire biological wastewater treatment plant in order to evaluate, through simulations, different control techniques. This benchmark plays the role of an activated sludge process used for removal of organic matter and nitrogen from domestic effluents. The development of this simulator is based on models widely accepted by the international community and is implemented in Matlab/Simulink (The MathWorks, Inc. platform. The benchmark considers plant layout and the effects of influent characteristics. It also includes a test protocol for analyzing the open and closed-loop responses of the plant. Examples of control applications in the benchmark are implemented employing conventional PI controllers. The following common control strategies are tested: dissolved oxygen (DO concentration-based control, respirometry-based control and nitrate concentration-based control.

    To evaluate the feasibility, safety and effectiveness of a newly designed percutaneously implanted separate stent-graft (SSG) for the treatment of aortic aneurysms and dissections. Using a percutaneous technique, SSG placement (in the descending thoracic aorta in 26 cases and infrarenal abdominal aorta in 24) was attempted in 50 patients with aortic aneurysms (n=27) or dissection (n=23). All SSGs were individually constructed using self-expandable nitinol stents and a Dacron graft, and were introduced through a 12 F sheath and expanded to a diameter of 20-34 mm. In all cases, vascular access was through the femoral artery. The clinical status of each patient was monitored, and postoperative CT was performed within one week of the procedure and at 3-6 month intervals afterwards. Endovascular stent-graft deployment was technically successful in 49 of 50 patients (98%). The one failure was due to torsion of the unsupported graft during deployment. Successful exclusion of aneurysms and the primary entry tears of dissections was achieved in all but three patients with aortic dissection. All patients in whom technical success was achieved showed complete thrombosis of the thoracic false lumen or aneurysmal sac, and the overall technique success rate was 92%. In addition, sixteen patients demonstrated complete resolution of the dissected thoracic false lumen (n=9) or aneurysmal sac (n=7). Immediate post-operative complications occurred at the femoral puncture site in one patient with an arteriovenous fistula, and in two, a new saccular aneurysm developed at the distal margin of the stent. No patients died, and there was no instance of paraplegia, stroke, side-branch occlusion or infection during the subsequent mean follow-up period of 9.4 (range, 2 to 26) months. In patients with aortic aneurysm and dissection, treatment with a separate percutaneously inserted stent-graft is technically feasible, safe, and effective.

  15. Modified steel basket technique for the treatment of equine cervical vertebral stenotic myelopathy - a case report

    2015-08-01

    Full Text Available Cervical vertebral stenotic myelopathy (CVSM, also known as cervical ataxia or wobbler syndrome, is caused by the narrowing of the medullary canal due to a malformation of the cervical vertebrae, resulting in compression of the spinal cord and neurological alterations such as ataxia, hypermetria, weakness, and abnormal stance. The treatment options can be conservative or surgical, with varied effectiveness. The most appropriate surgical technique in the majority of cases is arthrodesis, providing quick and efficient decompression of the spinal cord. The goal of this case report is to present an equine patient with CVSM that was surgically treated using a new modified cage model. The diagnosis was based on history, clinical signs and radiographic evidence of spinal cord compression between the C3 and C4 vertebrae, after ruling out possible infectious agents. The surgical procedure for the decompression and stabilization of the point of stenosis was performed using a modified Cloward’s technique and a new cage model fixed with two screws. Evidence of fusion was obtained by periodic radiographs over six months of postoperative care. The new cage model used in this surgery proved to be efficient for the decompression and stabilization of the vertebrae, allowing arthrodesis development and remission of the clinical signs. Fixation of the cage with screws reduces the risk of migration of the implant.

    There is an immediate need to develop innovative and more effective techniques for treatment of wastewaters as regulations on effluent wastewater discharge are becoming increasingly prevalent. The mining and metallurgical industries generate wastewaters that contain stable oil-in-water emulsions, arising from residues of liquid streams that serve the purpose of lubrication, cooling, cleaning and corrosion prevention in the equipment used in those industries. Chemically stabilized oil-water emulsions produced in the mineral industries can be treated using an electrocoagulation technique that considers the effects of operating parameters such as initial pH, current density, reaction time, electrode area/liquid volume ratio and electrode materials on the separation of oil as measured by the chemical oxygen demand. The paper discussed electrocoagulation as well as the materials and methods for the study, including oil in water emulsions; the experimental apparatus; and the experimental procedure. It was concluded that the electrolysis of this kind of oil in water emulsions with aluminum electrodes resulted in pH neutralization regardless of the initial pH tested. 18 refs., 4 figs.

    Varicose veins are common and their management has undergone a number of changes over the years. Surgery has been the traditional treatment option, but towards the 21st century, new endovenous thermal ablation techniques, namely, radiofrequency ablation and endovenous laser ablation, were introduced which have revolutionised the way varicose veins are treated. These minimally invasive techniques are associated with earlier return to normal activity and less pain, as well as enabling procedures to be carried out as day cases. They are, however, also known to cause a number of side-effects and involve infiltration of tumescent fluid which can cause discomfort. Non-thermal, non-tumescent methods are believed to be the answer to these unwelcome effects. Ultrasound-guided foam sclerotherapy is one such non-thermal, non-tumescent method and, despite a possible lower occlusion, has been shown to improve the quality of life of patients. The early results of two recently launched non-thermal, non-tumescent methods, mechanochemical ablation and cyanoacrylate glue, are promising and are discussed.

    Due to their anatomical characteristics and the complexity of the procedures required to obtain their complete occlusion, the treatment of giant intracranial aneurysms is a real challenge. Direct reconstructive strategies, whether by interventional neuroradiology (coils, stents) or microsurgical (clipping) means, are not always applicable and, in patients that would not tolerate parent or collateral artery sacrifice, the adjunction of a revascularization procedure using a bypass technique might be necessary. Cerebral arterial bypasses can be classified according to their function (3 types: flow replacement, flow reversal or protective), the branching mode of the graft used (3 types: pedicled, interpositional or in situ), the sites of anastomosis (2 types: extracranial-intracranial or intracranial-intracranial) and the class of flow they are supposed to provide (3 types: low-, intermediate- or high-flow). In this article, the authors review the different aspects in the management of patients with a giant intracranial aneurysm using a bypass: preoperative work-up, types of bypass and indications, surgical techniques and results.

    Full Text Available AbstractObjective:Report initial experience with the Frozen Elephant Trunk technique.Methods:From July 2009 to October 2013, Frozen Elephant Trunk technique was performed in 21 patients (66% male, mean age 56 ±11 years. They had type A aortic dissection (acute 9.6%, chronic 57.3%, type B (14.3%, all chronic and complex aneurysms (19%. It was 9.5% of reoperations and 38% of associated procedures (25.3% miocardial revascularization, 25.3% replacement of aortic valve and 49.4% aortic valved graft. Aortic remodeling was evaluated comparing preoperative and most recent computed tomography scans. One hundred per cent of complete follow-up, mean time of 28 months.Results:In-hospital mortality of 14.2%, being 50% in acute type A aortic dissection, 8.3% in chronic type A aortic dissection, 33.3% in chronic type B aortic dissection and 0% in complex aneurysms. Mean times of cardiopulmonary bypass (152±24min, myocardial ischemia (115±31min and selective cerebral perfusion (60±15min. Main complications were bleeding (14.2%, spinal cord injury (9.5%, stroke (4.7%, prolonged mechanical ventilation (4.7% and acute renal failure (4.7%. The need for second-stage operation was 19%. False-lumen thrombosis was obtained in 80%.Conclusion:Frozen Elephant Trunk is a feasible technique and should be considered. The severity of the underlying disease justifies high mortality rates. The learning curve is a reality. This approach allows treatment of more than two segments at once. Nonetheless, if a second stage is made necessary, it is facilitated.

  20. Nanomaterial characterization through image treatment, 3D reconstruction and AI techniques

    Lopez de Uralde Huarte, Juan Jose

    Nanotechnology is not only the science of the future, but it is indeed the science of today. It is used in all sectors, from health to energy, including information technologies and transport. For the present investigation, we have taken carbon black as a use case. This nanomaterial is mixed with a wide variety of materials to improve their properties, like abrasion resistance, tire and plastic wear or tinting strength in pigments. Nowadays, indirect methods of analysis, like oil absorption or nitrogen adsorption are the most common techniques of the nanomaterial industry. These procedures measure the change in the physical state while adding oil and nitrogen. In this way, the superficial area is estimated and related with the properties of the material. Nevertheless, we have chosen to improve the existent direct methods, which consist in analysing microscopy images of nanomaterials. We have made progress in the image processing treatments and in the extracted features. In fact, some of them have overcome the existing features in the literature. In addition, we have applied, for the first time in the literature, machine learning to aggregate categorization. In this way, we identify automatically their morphology, which will determine the final properties of the material that is mixed with. Finally, we have presented an aggregate reconstruction genetic algorithm that, with only two orthogonal images, provides more information than a tomography, which needs a lot of images. To summarize, we have improved the state of the art in direct analysing techniques, allowing in the near future the replacement of the current indirect techniques.

  1. Venous leakage treatment revisited: pelvic venoablation using aethoxysclerol under air block technique and Valsalva maneuver

    2015-03-01

    Full Text Available Objective: We evaluated the effectiveness of pelvic vein embolization with aethoxysclerol in aero-block technique for the treatment of impotence due to venous leakage in men using sildenafil for intercourse. The aim of the procedure was to reduce the use of sildenafil. Methods: A total of 96 patients with veno-occlusive dysfunction, severe enough for the need of PDE5 inhibitors for vaginal penetration, underwent pelvic venoablation with aethoxysclerol. The mean patient age was 53.5 years. Venous leaks were identified by Color Doppler Ultrasound after intracavernous alprostadil injection. Under local anesthesia a 20-gauge needle was inserted into the deep dorsal penile vein. The pelvic venogram was obtained through deep dorsal venography. Aethoxysclerol 3% as sclerosing agent was injected after air-block under Valsalva manoeuver. Success was defined as the ability to achieve vaginal insertion without the aid of any drugs, vasoactive injections, penile prosthesis, or vacuum device. Additionally, a pre- and post- therapy IIEF score and a digital overnight spontaneous erections protocol (OSEP with the NEVA™-system was performed. Results: At 3 month follow-up 77 out of 96 patients (80.21% reported to have erections sufficient for vaginal insertion without the use of any drug or additional device. Four (4.17% patients did not report any improvement. Follow up with color Doppler ultrasound revealed a new or persistent venous leakage in 8 (8.33% of the patients. No serious complications occurred. Conclusions: Our new pelvic venoablation technique using aethoxysclerol in air-block technique was effective, minimally invasive, and cost-effective. All patients were able to perform sexual intercourse without the previously used dosage of PDE5 inhibitor. This new method may help in patients with contra-indications against PDE5 inhibitors, in patients who cannot afford the frequent usage of expensive oral medication or those who do not fully respond to PDE5

    The treatment of non-unions with large bone defects or osteitis is a major challenge in orthopedic and trauma surgery. A new concept of therapy is a two-step procedure: Masquelet technique according to the diamond concept. Between February 2010 and June 2014, 55 patients with tibia non-unions or infections were treated in a two-step Masquelet technique in our center. The patients' average age was 48 (median 50; minimum 15-maximum 72) with an average BMI (body mass index) of 28 (27; 18-52). There were 10 (18 %) female and 45 (82 %) male patients in the group. All study patients went through a follow up. Bone healing and clinical functional data were collected, as well as data according to subjective patient statements about pain and everyday limitations. In 42 cases (76.4 %) the outcome was a sufficient bony consolidation. On average, the time to heal was 10.3 (8, 5; 3-40) months, defect gaps were 4 cm (3 cm; 0,6-26 cm), and on average the patients had had 6 (median 4; range 1-31) previous operations . In all cases patients received osteosynthesis as well as a defect filling with RIA (reamer-irrigator-aspirator), and growth factor BMP-7 (bone morphogenetic protein-7). In 13 cases (23.6 %) there was no therapeutic success. In the evaluation of the SF12 questionnaire the mental health score increased from 47.4 (49.1; 27.6-65.7) to 49.8 (53.0; 28.7-69.4) and the well-being score from 32.7 (32.7;16.9-55.7) to 36.6 (36.5; 24.6-55.9). The two-step bone grafting method in the Masquelet technique used for tibia non-unions according to the diamond concept is a promising treatment option. Its application for tibia shaft non-unions with large bone defects or infections means a high degree of safety for the patient.

    Purpose: The purpose of this presentation is to discuss the radiation safety and dosimetric technique used for the therapeutic procedure using Y-90 microspheres through intra -arterial administration on patients with liver metastasis Methods: The radiation dosimetry, technique and safety aspects of 14 patients with primary and metastatic liver cancer, treated with Y-90 microsphere (SIR spheres) are discussed. The liver and tumor volumes were determined using the CT and MR scans . The images were imported into the treatment planning system and the liver and tumor volumes and the volume of the liver affected were outlined and the volume calculation was performed using the software. The lung shunt fraction (LSF) and tumor to liver uptake ratio (TLR) were determined using the nuclear medicine SPECT imaging with Tc-99m MAA. The absorbed dose to the target volume in liver was calculated using the following equation:Dose ? (Gy) = C x E? x 5.92 x 10-6 (Gy/s) x T(1/2)(days) x 1.44 x 8.64 x 104 (s) The distribution of activity in the tumor bed was confirmed by post Y-90 administration imaging using the Bremsstrahlung peak at 30% window. The patient and the procedure room were surveyed and radiation safety instructions were given to the patient Results: The tumor volume ranged from 77 cc to 700 cc, tumor to liver uptake ranged from 3 to 12. The lung shunt fraction varied from 1.08% to 9.0%. The activity administered ranged from 1.0GBq to 2.5 GBq, . The radiation survey in contact with the patient ranged from 1.8 mR/hr to 2.5 mR/hr and reading at 1 meter was less than 0.2 mR/hr Conclusion: The technique for radiation dosimetry and radiation safety for Y-90 microsphere therapy is established. The post treatment imaging helped to confirm the distribution of Y-90 microspheres inside the tumor bed.

    Objective To assess a new intervention for reestablishing the second hepatic hilum by means of puncturing and stenting the liver tissue between the intrahepatic vena cava and a hepatic vein for the treatment of Budd-Chiari syndrome (BCS).Methods Two patients with BCS, in which no second hepatic hilum structure was found in transhepatic venography, underwent an interventional procedure of canalizing and stenting the parenchyma tract between the intrahepatic vena cava and a hepatic vein. The procedures were performed in the percutaneous transhepatic and right jugular vein, respectively. A metallic stent with a 10 mm diameter was implanted to maintain tract patency. Results The free hepatic vein pressure (FHVP) of both patients decreased from 37 mm Hg to 5 mm Hg and from 28 mm Hg to 4 mm Hg, respectively, after the procedure. The complication of hemorrhage due to puncture was observed in one patient. Both patients maintained hepatic improvements in 3-year follow-up. Both clinical conditions and laboratory values were significantly improved after the procedure. Furthermore, the stented canals (the reestablished second hepatic hilum) maintained patent with normal FHVP, which was confirmed by control venography.Conclusion The new technique provides a simple, safe, effective, and relatively inexpensive treatment of Budd-Chiari syndrome. Long-lasting effectiveness is expected.

    Open synovectomy remains the treatment of choice for pigmented villonodular synovitis (PVNS) of the hip but has shown modest results compared with the treatment of other joints. Recent advances in hip arthroscopy permit a thorough evaluation of the joint surfaces, improved access, and decreased postoperative morbidity. We describe an arthroscopic synovectomy technique for PVNS of the hip. The use of additional arthroscopic portals and creation of a large capsulotomy enable successful visualization and extensive synovectomy of the entire synovial lining of the hip. The T-capsulotomy enables extensive soft-tissue retraction for complete exposure. The midanterior portal enables use of an arthroscopic grasper and shaver to directly access and excise the synovial lining of the peripheral compartment while avoiding damage to the medial and lateral retinacular vessels. Technical innovations in hip arthroscopy have enhanced visualization in the central and peripheral compartments, as well as instrument management and diagnostic evaluation of the capsule, therefore allowing enhanced management of PVNS of the hip.

    Historically, anatomical CT and MR images were used to delineate the gross tumour volumes (GTVs) for radiotherapy treatment planning. The capabilities offered by modern radiation therapy units and the widespread availability of combined PET/CT scanners stimulated the development of biological PET imaging-guided radiation therapy treatment planning with the aim to produce highly conformal radiation dose distribution to the tumour. One of the most difficult issues facing PET-based treatment planning is the accurate delineation of target regions from typical blurred and noisy functional images. The major problems encountered are image segmentation and imperfect system response function. Image segmentation is defined as the process of classifying the voxels of an image into a set of distinct classes. The difficulty in PET image segmentation is compounded by the low spatial resolution and high noise characteristics of PET images. Despite the difficulties and known limitations, several image segmentation approaches have been proposed and used in the clinical setting including thresholding, edge detection, region growing, clustering, stochastic models, deformable models, classifiers and several other approaches. A detailed description of the various approaches proposed in the literature is reviewed. Moreover, we also briefly discuss some important considerations and limitations of the widely used techniques to guide practitioners in the field of radiation oncology. The strategies followed for validation and comparative assessment of various PET segmentation approaches are described. Future opportunities and the current challenges facing the adoption of PET-guided delineation of target volumes and its role in basic and clinical research are also addressed. (orig.)

    A new planning method for Craniospinal Irradiation by Eclipse treatment planning system using Field alignment, Field-in-Field technique was developed. Advantage of this planning method was also studied retrospectively for previously treated five patients of medulloblastoma with variable spine length. Plan consists of half beam blocked parallel opposed cranium, and a single posterior cervicospine field was created by sharing the same isocenter, which obviates divergence matching. Further, a single symmetrical field was created to treat remaining Lumbosacral spine. Matching between a inferior diverging edge of cervicospine field and superior diverging edge of a Lumbosacral field was done using the field alignment option. 'Field alignment' is specific option in the Eclipse Treatment Planning System, which automatically matches the field edge divergence as per field alignment rule. Multiple segments were applied in both the spine field to manage with hot and cold spots created by varying depth of spinal cord. Plan becomes fully computerized using this field alignment option and multiple segments. Plan evaluation and calculated mean modified Homogeneity Index (1.04 and 0.1) ensured that dose to target volume is homogeneous and critical organ doses were within tolerance. Dose variation at the spinal field junction was verified using ionization chamber array (I'MatriXX) for matched, overlapped and gap junction spine fields; the delivered dose distribution confirmed the ideal clinical match, over exposure and under exposure at the junction, respectively. This method is simple to plan, executable in Record and Verify mode and can be adopted for various length of spinal cord with only two isocenter in shorter treatment time.

    TENAWA project (Treatment Techniques for Removing Natural Radionuclides from Drinking Water) was carried out on a cost-shared basic with the European Commission (CEC) under the supervision of Directorate-General XII, Radiation Protection Unit. TENAWA project was started because in several European countries ground water supplies may contain high amounts of natural radionuclides. During the project both laboratory and field research was performed in order to test the applicability of different equipment and techniques for removing natural radionuclides from drinking water. The measurable objectives of the project were: to give recommendations on the most suitable methods for removing radon ({sup 222}Rn), uranium ({sup 238,234}U), radium ({sup 226}, {sup 228}Ra), lead ({sup 210}Pb) and polonium ({sup 210}Po) from drinking water of different qualities (i.e. soft, hard, iron-, manganese- and humus-rich, acidic) to test commercially available equipment for its ability to remove radionuclides; to find new materials, absorbents and membranes effective in the removal of radionuclides and to issue guidelines for the treatment and disposal of radioactive wastes produced in water treatment. Radon could be removed efficiently (>95%) from domestic water supplies by both aeration and granular activated carbon (GAC) filtration. Defects in technical reliability or radon removal efficiency were observed in some aerators. The significant drawback of GAC filtration was the elevated gamma dose rates (up to 120 {mu}Sv/h) near the filter and the radioactivity of spent GAC. Aeration was found to be a suitable method for removing radon at waterworks, too. The removal efficiencies at waterworks where the aeration process was designed to remove radon or carbon dioxide were 67-99%. If the aeration process was properly designed, removal efficiencies higher than 95% could be attained. Uranium could best be removed (>95%) with strong basic anion exchange resins and radium by applying strong

    AIM: To evaluate the therapeutic effect of the combined use of early short-term somatostatin and conventional integrated Chinese and Western medicine in treating severe acute pancreatitis.METHODS: Sixty patients with severe acute pancreatitis were divided at random into a somatostatin group and a basic treatment group. Both groups received integrated traditional Chinese and Western medicine without surgery.For patients in the somatostatin group, somatostatin was infused intravenously 250 μg/h for 72 h; other medications were the same as in the basic treatment group. In both groups, comparisons of therapeutic effectiveness were made in terms of morbidity of organic dysfunction and mortality rate, and severity of the disease according to serum levels of C-reaction protein, scores of acute physiology and chronic health evaluation (APACHE Ⅱ), and scores of Balthazar-CT.RESULTS: The indexes for C-reaction protein levels on the fourth and seventh days, and APACHE Ⅱ scores on the seventh day after treatment, were significantly improved in the somatostatin group than in the basic treatment group. The morbidity of organic dysfunction was lower in the somatostatin group than in the basic treatment group, although the difference was not statistically significant. There was no significant difference in mortality between the two groups.CONCLUSION: We conclude that combined traditional Chinese and Western medicines with an early short-term use of somatostatin can improve the condition of patients with severe acute pancreatitis.

    Full Text Available Background: The recent addition of Premenstrual Dysphoric Disorder (PMDD to the Diagnostic and Statistical Manual (5th ed. has highlighted the seriousness of this disorder. Many alternatives to psychoactive medication in the form of vitamins, minerals, and plant extracts have been trialled by women seeking a natural treatment approach. We plan to explore whether a well validated micronutrient formula, EMPowerplus Advanced, can outperform a recognized single nutrient treatment, vitamin B6, for the treatment of Premenstrual Syndrome (PMS. Methods: This will be a randomized treatment control study. Eighty women will be recruited and assigned to one of two treatment groups; EMPowerplus Advanced or vitamin B6. Baseline daily data will be collected for an initial two cycles, followed by three months of active treatment. A natural follow up will take place three cycles post treatment. Results: The primary outcome measure will be PMS change scores as based on results from the Daily Record of Severity of Problems (DRSP. The number of treatment responders for each of the two groups will yield a comparison score between the two treatments, with participants deemed as a responder if they show a total PMS score improvement of 50% from their baseline scores on the DRSP. Conclusion: If a micronutrient formula proves more effective for treating PMS, not only does it give women suffering from the condition a viable treatment option, but it may also suggest one cause of PMS; that is insufficient minerals and vitamins.

This study evaluated the efficacy of a nutritional complement rich in omega-3 fatty acids in patients with mild or moderate plaque psoriasis. Thirty patients were recruited, 15 of whom were given topical treatment with tacalcitol, forming the control group. The remaining 15 patients were given topical tacalcitol and 2 capsules of Oravex® daily. Three visits, the baseline, intermediate (week 4, and final (week 8, were held over an 8-week period. The main efficacy endpoints were the Psoriasis Area and Severity Index (PASI, Nail Psoriasis Severity Index (NAPSI and Dermatological Life Quality Index (DLQI. A clear and significant improvement was observed in all the efficacy endpoints in both groups between the baseline visit and the end visit. This improvement was significantly greater in the group treated additionally with Oravex® than in the control group. Supplementary treatment with omega-3 fatty acids complements topical treatment in psoriasis, and makes a significant contribution to reducing PASI and NAPSI and improving DLQI; and to reducing scalp lesion and pruritus, erythema, scaling, and infiltration of the treated areas.Keywords: psoriasis, metabolic syndrome, vitamin D derivates, omega-3 fatty acids, tacalcitol

    Full Text Available Purpose: To evaluate the clinical outcomes of intrastromal corneal ring segment (ICRS implantation in patients with keratoconus using a mechanical implantation technique. Materials and Methods: Thirty eyes of 17 patients with keratoconus were enrolled. ICRSs (Keraring were implanted after dissection of the tunnel using Tunc′s specially designed dissector under suction. A complete ophthalmic examination was performed, including uncorrected distance visual acuity (UDVA, corrected distance visual acuity (CDVA, spherical equivalent, keratometric readings, inferosuperior asymmetry index (ISAI, and ultrasound pachymetry. All 3-, 6-, and 12-month follow-ups were completed, and statistical analysis was performed. Results: The mean preoperative UDVA for all eyes was 1.36 ± 0.64 logMAR. At 12 months, the mean UDVA was 0.51 ± 0.28 logMAR (P = 0.001, and the mean preoperative CDVA was 0.57 ± 0.29 logMAR, which improved to 0.23 ± 0.18 (P = 0.001 at 1 year. There was a significant reduction in spherical equivalent refractive error from -6.42 ± 4.69 diopters (D preoperatively to -1.26 ± 1.45 D (P = 0.001 at 1 year. In the same period, the mean K-readings improved from 49.38 ± 3.72 D to 44.43 ± 3.13 D (P = 0.001, and the mean ISAI improved from 7.92 ± 3.12 to 4.21 ± 1.96 (P = 0.003. No significant changes in mean central corneal thickness were observed postoperatively. There were no major complications during and or after surgery. Conclusion: ICRS implantation using a unique mechanical dissection technique is a safe and effective treatment for keratoconus. All parameters improved by the 1-year follow-up.

    Full Text Available Abstract Background Globally syphilis is an important yet preventable cause of stillbirth, neonatal mortality and morbidity. Objectives This review sought to estimate the effect of detection and treatment of active syphilis in pregnancy with at least 2.4MU benzathine penicillin (or equivalent on syphilis-related stillbirths and neonatal mortality. Methods We conducted a systematic literature review of multiple databases to identify relevant studies. Data were abstracted into standardised tables and the quality of evidence was assessed using adapted GRADE criteria. Where appropriate, meta-analyses were undertaken. Results Moderate quality evidence (3 studies supports a reduction in the incidence of clinical congenital syphilis of 97% (95% c.i 93 – 98% with detection and treatment of women with active syphilis in pregnancy with at least 2.4MU penicillin. The results of meta-analyses suggest that treatment with penicillin is associated with an 82% reduction in stillbirth (95% c.i. 67 – 90% (8 studies, a 64% reduction in preterm delivery (95% c.i. 53 – 73% (7 studies and an 80% reduction in neonatal deaths (95% c.i. 68 – 87% (5 studies. Although these effect estimates were large and remarkably consistent across studies, few of the studies adjusted for potential confounding factors and thus the overall quality of the evidence was considered low. However, given these large observed effects and a clear biological mechanism for effectiveness the GRADE recommendation is strong. Conclusion Detection and appropriate, timely penicillin treatment is a highly effective intervention to reduce adverse syphilis-related pregnancy outcomes. More research is required to identify the most cost-effective strategies for achieving maximum coverage of screening for all pregnant women, and access to treatment if required.

    Full Text Available Background: Abnormalities in fatty acid metabolism and membrane fatty acid composition play a part in a wide range of neurodevelopmental and psychiatric disorders. Altered fatty acid homeostasis as a result of insufficient dietary supplementation, genetic defects, the function of enzymes involved in their metabolism, or mitochondrial dysfunction contributes to the development of autism. Objective: This study evaluates the association of altered brain lipid composition and neurotoxicity related to autism spectrum disorders in propionic acid (PA–treated rats. Design: Forty-eight young male western albino rats were used in this study. They were grouped into six equal groups with eight rats in each. The first group received only phosphate buffered saline (control group. The second group received a neurotoxic dose of buffered PA (250 mg/kg body weight/day for 3 consecutive days. The third and fourth groups were intoxicated with PA as described above followed by treatment with either coenzyme Q (4.5 mg/kg body weight or melatonin (10 mg/kg body weight for 1 week (therapeutically treated groups. The fifth and sixth groups were administered both compounds for 1 week prior to PA (protected groups. Methyl esters of fatty acid were extracted with hexane, and the fatty acid composition of the extract was analyzed on a gas chromatography. Results: The obtained data proved that fatty acids are altered in brain tissue of PA-treated rats. All saturated fatty acids were increased while all unsaturated fatty acids were significantly decreased in the PA-treated group and relatively ameliorated in the pre–post melatonin and coenzyme Q groups. Conclusions: Melatonin and coenzyme Q were effective in restoring normal level of most of the impaired fatty acids in PA-intoxicated rats which could help suggest both as supplements to ameliorate the autistic features induced in rat pups.

    Hypothyroid patients experience fatigue-related symptoms despite adequate thyroid hormone replacement. Thyroid hormone plays an essential role in carnitine-dependent fatty acid import and oxidation. We investigated the effects of L-carnitine supplementation on fatigue in patients with hypothyroidism. In total, 60 patients (age 50.0 ± 9.2 years, 3 males, 57 females) who still experienced fatigue (fatigue severity scale [FSS] score ≥ 36) were given L-carnitine (n = 30, 990 mg L-carnitine twice daily) or placebo (n = 30) for 12 weeks. After 12 weeks, although neither the FSS score nor the physical fatigue score (PFS) changed significantly, the mental fatigue score (MFS) was significantly decreased by treatment with L-carnitine compared with placebo (from 4.5 ± 1.9 to 3.9 ± 1.5 vs. from 4.2 ± 1.8 to 4.6 ± 1.6, respectively; P carnitine group, 75.0%, 53.6%, and 50.0% of patients showed improvement in the FSS score, PFS, and MFS, respectively, but only 20.0%, 24.0%, and 24.0%, respectively, did so in the placebo group (all P carnitine compared with placebo. Additionally, the MFS was significantly improved in patients taking thyroid hormone after thyroid cancer surgery. These results suggest that L-carnitine supplementation may be useful in alleviating fatigue symptoms in hypothyroid patients, especially in those younger than 50 years and those who have hypothyroidism after thyroidectomy for thyroid cancer (ClinicalTrials.gov: NCT01769157).

    Full Text Available Abstract Background The incidence of spinal deformity in children with Prader-Willi syndrome (PWS is high, with 86% of these patients found to have a significant structural scoliosis; however, there are very few case reports describing surgical treatment for this deformity. Methods The authors reviewed a case series consisting of 6 patients who underwent spine surgery for scoliosis. Children's mean age at index surgery was 12 years and 10 months (range, 10 to 15 yrs. Clinical evaluation revealed the typical phenotypic features of the PWS in all of the patients; 4 subjects had a karyotype confirmation of PWS. Major structural curves showed preoperative mean Cobb angles of 80.8° (range, 65° to 96°. Hybrid instrumentation with sublaminar wires, hooks and screws was used in the first 2 patients, while the remaining 4 were treated with titanium pedicle screw constructs. Results The mean clinical and radiological follow-up was 3 years and 10 months (range, 2 years to 9 years. Major complication rate was 50%. One patient who developed a major intraoperative complication (paraparesis prevented spinal fusion to be obtained: the neurologic deficit resolved completely after instrumentation removal. Solid arthrodesis and deformity correction in both coronal and sagittal plane was, however, achieved in the other 5 cases and no significant curve progression was observed at follow-up. Another major short-term complication was encountered 3 months after surgery in a patient who experienced the detachment of a distally located rod and required correction through revision surgery and caudal extension by one level. Cervico-thoracic kyphosis was seen in 1 patient who did not require revision surgery. Conclusions Spine reconstructive surgery in patients with PWS is rare and highly demanding. The best method of reconstruction is posterior multilevel pedicle screw fixation. Moreover, even with modern techniques, the risk of complications is still high. These new

Patients were randomly divided into two groups: Group A was treated using a hook plate and Group B with autogenous semitendinosus graft and endobutton technique. All participants were followed up for 12 months. Radiographic examinations were performed every 2 months postoperatively, and clinical evaluation was performed using the Constant–Murley score at the last follow-up.Results: Results indicated that patients in Group B showed higher mean scores (90.3±5.4 than Group A (80.4±11.5 in terms of Constant–Murley score (P=0.001. Group B patients scored higher in terms of pain (P=0.002, activities (P=0.02, range of motion (P<0.001, and strength (P=0.004. In Group A, moderate pain was reported by 2 (8.7% and mild pain by 8 (34.8% patients. Mild pain was reported by 1 (4.3% patient in Group B. All patients in Group B maintained complete reduction, while 2 (8.7% patients in Group A experienced partial reduction loss. Two patients (8.7% encountered acromial osteolysis on latest radiographs, with moderate shoulder pain and limited range of motion.Conclusion: Autogenous semitendinosus graft and endobutton technique showed better results compared with the hook plate method and exhibited advantages of fewer complications such as permanent pain and acromial osteolysis.

    Lagophthalmos is the major functional complication of facial paralysis because, in the absence of treatment, it can lead to corneal scarring and blindness. This disorder can be treated in a number of ways, including levator lengthening by aponeurosis interposition, a technique developed by Paul Tessier. We assessed the benefits of this technique, and compared the results to those with other techniques, in particular, the use of gold implants. A total of 29 patients were operated by the same surgeon using levator lengthening by aponeurosis interposition as described by Paul Tessier. Aesthetic and functional results were assessed according to predefined criteria during patient consultation at 1 year and by the patients themselves (questionnaire). We reviewed other surgical techniques used to treat lagophthalmos and compared findings with previous international studies. The use of a gold plate implant remains the most widely used technique for the treatment of lagophthalmos. Although the functional results are good, the implant is always visible, leading to the disappearance of the superior palpebral fold and a risk of exposure and therefore of infection. Levator lengthening, a technique developed by Paul Tessier, allows identical functional results to be obtained, but conserves a natural appearance of the upper eyelid. It is a simple surgical procedure associated with a low morbidity rate. The lengthening of the levator by aponeurosis interposition is a simple, reliable, and easily reproducible technique allowing treatment of paralytic lagophthalmos with good results, in terms of both function and aesthetics.

    2010-01-01

    Full Text Available Study design: Retrospective, observational, open label. Objective: We investigated the efficacy of facet debridement for the treatment of facet joint pain. Summary of background data: Facet joint disease, often due to degenerative arthritis, is common cause of chronic back pain. In patients that don't respond to conservative measures, nerve ablation may provide significant improvement. Due to the ability of peripheral nerves to regenerate, ablative techniques of the dorsal nerve roots often provide only temporary relief. In theory, ablation of the nerve end plates in the facet joint capsule should prevent reinnervation. Methods: All patients treated with endoscopic facet debridement at our clinic from 2003-2007 with at least 3 years follow-up were included in the analysis. Primary outcome measure was percent change in facet-related pain as measured by Visual Analog Scale (VAS score at final follow-up visit. Results: A total of 174 people (77 women, 97 men; mean age 64, range 22-89 were included. Location of facet pain was cervical in 45, thoracic in 15, and lumbar in 114 patients. At final follow-up, 77%, 73%, and 68% of patients with cervical, thoracic, or lumbar disease, respectively, showed at least 50% improvement in pain. Mean operating time per joint was 17 minutes (range, 10-42. Mean blood loss was 40 ml (range, 10-100. Complications included suture failure in two patients, requiring reclosure of the incision. No infection or nerve damage beyond what was intended occurred. Conclusions: Our results demonstrate a comparable efficacy of endoscopic facet debridement compared to radiofrequency ablation of the dorsal nerve branch, with durable results. Large scale, randomized trials are warranted to further evaluate the relative efficacy of this surgical treatment in patients with facet joint disease.

    Full Text Available INTRODUCTION: Cervical injury in a polytrauma patient is one of the most critical injuries. The aim of this study was to compare the lateral mass screw technique with the Hartshill rectangle technique for treatment of such cases. MATERIALS AND METHODS: This prospective study consisted of 40 patients. Both groups were followed for three years clinically and radiologically. RESULTS: In the lateral mass technique, there were no cases of vertebral artery injury, radiculopathy, screw pullout, dural tears, residual kyphosis or persistent pain. In the Hartshill technique 3 patients experienced intra- operative dural tears, 1 case of wire breakage at the six months follow up, 6 patients with persistent neck pain and 1 with worsening neurological status. One hundred per cent fusion was achieved in both groups. There was significant radiation exposure in the lateral mass group. Post-operative immobilisation was required only in the Hartshill. CONCLUSION: Lateral mass screw technique is definitely a relatively better procedure. But Hartshill rectangle still stands out in certain practical situations.

    Full Text Available Abstract Background Adjusting for laboratory test results may result in better confounding control when added to administrative claims data in the study of treatment effects. However, missing values can arise through several mechanisms. Methods We studied the relationship between availability of outpatient lab test results, lab values, and patient and system characteristics in a large healthcare database using LDL, HDL, and HbA1c in a cohort of initiators of statins or Vytorin (ezetimibe & simvastatin as examples. Results Among 703,484 patients 68% had at least one lab test performed in the 6 months before treatment. Performing an LDL test was negatively associated with several patient characteristics, including recent hospitalization (OR = 0.32, 95% CI: 0.29-0.34, MI (OR = 0.77, 95% CI: 0.69-0.85, or carotid revascularization (OR = 0.37, 95% CI: 0.25-0.53. Patient demographics, diagnoses, and procedures predicted well who would have a lab test performed (AUC = 0.89 to 0.93. Among those with test results available claims data explained only 14% of variation. Conclusions In a claims database linked with outpatient lab test results, we found that lab tests are performed selectively corresponding to current treatment guidelines. Poor ability to predict lab values and the high proportion of missingness reduces the added value of lab tests for effectiveness research in this setting.

    Iron deficiency and helminth infections are two common conditions of children in developing countries. The consequences of helminth infection in young children are not well described, and the efficacy of low dose iron supplementation is not well documented in malaria-endemic settings. A 12-mo randomized, placebo controlled, double-blind trial of 10 mg daily iron and/or mebendazole (500 mg) every 3 mo was conducted in a community-based sample of 459 Zanzibari children age 6-71 mo with hemoglobin > 70 g/L at baseline. The trial was designed to examine treatment effects on growth, anemia and appetite in two age subgroups. Iron did not affect growth retardation, hemoglobin concentration or mild or moderate anemia (hemoglobin children children children's appetite, according to mothers' report. In this study, iron's effect on anemia was limited, likely constrained by infection, inflammation and perhaps other nutrient deficiencies. Mebendazole treatment caused unexpected and significant reductions in wasting malnutrition and anemia in very young children with light infections. We hypothesize that incident helminth infections may stimulate inflammatory immune responses in young children, with deleterious effects on protein metabolism and erythropoiesis.

This study was to investigate the clinical and angiographic outcomes of the treatment of the huge dissecting aneurysms involving the BA by the internal trapping (IT technique. Methods: We retrospectively studied 15 patients with the huge dissecting aneurysms involving the BA treated by the IT technique between September 2005 and September 2014 in Department of Interventional Neuroradiology of Beijing Tiantan Hospital. Clinical and angiographic data were reviewed and evaluated. Results: All patients were treated by the IT technique. That meant the dissecting artery and aneurysm segments were completed occlusion. After the procedure, the angiography demonstrated that all the dissecting artery and aneurysm segments were completed occlusion. Follow-up angiography was performed at 3-6 months or 12-18 months after the endovascular treatment (median 8 months, 14 patients had a good recovery. Re-canalization occurred in one patient whose aneurysm involved in bilateral vertebral arteries and the two third of the middle-lower BA. After the second treatment, the patient died by the ventricular tachycardia. Conclusions: The IT technique is a technically feasible and safe alternative for the treatment of BA dissecting aneurysms, but it is not necessarily the safest or most definitive treatment modality. The ideal treatment of the huge dissecting aneurysms involving the BA remains debatable and must be investigated on a case-by-case basis.

    Full Text Available 【Abstract】Objective: To evaluate clinical outcome of suture anchors in strengthening both acromioclavicular and coracoclavicular ligaments in the surgical treatment of acromioclavicular joint dislocation. Methods: Twenty-eight patients with acute traumatic Rockwood III, IV and V dislocations of the acromioclavicular joint surgically treated at our institute between October 2010 and January 2012 were recruited. All patients underwent open reduction combined with suture anchors. Function was evaluated using the ConstantMurley shoulder score. Clinical and radiographic shoulder ratings were evaluated using Taft criteria at 3, 6 and 12 months. Results:Two cases with fixation loosening were not included in final statistical analysis. Other patients obtained full joint reposition on immediate postoperative radiographs. Follow-up was performed with an average of 15.6 months (range, 12-19. After early range of motion exercises, 96.2% of the patients (25/26 could abduct and elevate their shoulders more than 90 degrees within postoperative 3 months. There was no infection. Average Constant-Murley score was 96.3 points (range, 94-100 and mean Taft shoulder rating was 10.7 points (range, 8-12 at 12 months. Conclusion: The suture anchor is a relatively simple technique and can avoid screw removal which is helpful in reconstructing both acromioclavicular and coracoclavicular ligaments in acute traumatic acromioclavicular joint dislocation.

    To evaluate the safety and efficacy of transurethral bipolar enucleation with a button electrode (B-TUEP) for the treatment of bladder outlet obstruction due to benign prostatic hyperplasia. Between July 2011 and March 2012, a single surgeon performed 50 B-TUEP. Preoperative and postoperative assessments included prostate-specific antigen, International Prostate Symptoms Score (IPSS), International Index of Erectile Function-5 (IIEF-5), quality of life (QoL) index, uroflowmetry with postvoiding residual (PVR) urinary volume, and prostate volume measured by transrectal ultrasonography. Intraoperatively, we evaluated B-TUEP time (enucleation and resection time). Perioperatively, we evaluated hemoglobin dosage, bladder irrigation time, catheterization time, acute urinary retention events, length of stay, patient readmission, and any endoscopic retreatments. Three months after surgery, 82% of the patients presented a significant improvement in maximum urine flow (Qmax; P prostate. B-TUEP using the Gyrus PK system is a rapid and safety technique with optimal outcomes. Copyright © 2015 Elsevier Inc. All rights reserved.

    The determination of the in situ emission rate of pollution sources can often not be done directly. In the absence of emission measurements, the emission rate of the source can be assessed by an inverse dispersion technique using ambient concentration measurements and meteorological parameters as input. The dispersion model used is the Austrian regulatory Gaussian model. The method is applied to a thermal waste recycling plant. Seven chemical species (butyl acetate, benzene, ethyl acetate, toluene, m/p-xylene, o-xylene and α-pinene), are identified as odorants and measured over a period of 1½ years in the prevailing wind direction leeward of the plant. The overall odour emission rate is calculated by adding the odour emission rate of all single species, using the individual odour threshold concentration. The estimated odour emission rates range between 206 and 8950 OU s -1, caused by the wide variety of the odour thresholds of the seven species. The higher value is in the upper range of odour emission rates of modern thermal treatment plants for waste.

    Full Text Available Polyvinyl alcohol (PVA sheets based nanofibers were produced by electrospinning technique. Postheat treatment of the produced PVA sheets with temperatures both below and above Tg to improve the mechanical properties of this material is conducted. The morphology, microstructures, and thermal degradation of the nanofibers sheets produced were investigated using scanning electron microscopy (SEM, transmission electron microscope (TEM, and thermal gravimetric analysis (TGA. Produced nanofibers are compact, and entangled with each other, with diameters from around 150 to 210. Some mechanical characteristics of the successfully produced PVA sheets, and heat-treated, are then conducted and assessed employing uniaxial tensile tests at different speeds ranging from 1 mm/min to 100 mm/min. The tensile test results obtained show that the PVA sheets are strain rate sensitive with increasing strength as the speed (i.e., strain rate increases. The yield tensile stress ranges from 2.411 to 6.981 MPa, the ductility (i.e., elongation percent from ∼21 to 60%, and Young modulus ranges from 103 to 0.137 KPa. However, for heat-treated samples, it is found that the yield strength increases almost by ∼35–40% more than the values of untreated cases with values reaching up to about 3.627–9.63 MPa.

    In this paper studies on the feasibility of harmlessness and resource of wastewater, which was discharged from a thermal power plant, by using slow rate filtration of land treatment technique for the fast recovery of vegetation in the Kubuqi sand land were carried out. The selected arbor, shrub and herbage in the land treatment system were poplar (Populus alba Var. Pyramidalis bunge), seabuckthorn (Hippophae rhamnoides) and sweet clover (Melilotus suaveolens) respectively. Three levels of wastewater hydraulic loading were designed in the field pilot experiment. They were high plot with 3000 mm/a irrigation (H), medium plot with 1500 mm/a irrigation (M) and low plot (L) with small volume of irrigation only used in the period of transplant seedlings. The performance indicate that the purification function of power plant wastewater by pre-treatment through combination of precipitation pool with storage ponds is effective and therefore the effluent after pretreatment can be used to irrigation vegetation. The experiment results show that the volume of tree crown for poplar in H plot and M plot was up to 1.07 and 2.21 times comparing with L plot respectively. The annual yield (dry weight) of sweet clover in H plot and M plot was up to 2.33 and 3.0 times comparing with L plot respectively. The height of seabuckthorn in H zone and M plot was up to 1.08 and 1.32 times comparing with L plot respectively. There is direct proportion between growth status of vegetation and hydraulic loading of irrigation. The contents of heavy metals for sweet clover (Cd 0.021 mg/kg, Pb<0.001 mg/kg, Cr <0.01 mg/kg, As 0.043 mg/kg) are much lower than the food standards of grain and vegetables, therefore the sweet clover for raising livestock is safe. Wastewater in this area is valuable source. Its reasonable utilization can contribute important benefits in economy and ecology in the ecological construction and developing effective agriculture and animal husbandry.

    To assess whether using an anterior oblique supraclavicular (SCV) field with a posterior axillary boost (PAB) field is an optimal technique for targeting axillary (AX) lymph nodes compared with two computed tomography (CT)-based techniques: (1) an SCV field with an anterior boost field and (2) intensity-modulated radiotherapy (IMRT). Ten patients with CT simulation data treated with postmastectomy radiation that included an SCV field were selected for the study. Supraclavicular nodes and AX Level I-III nodes within the SCV field were contoured and defined as the treatment target. Plans using the three techniques were generated and evaluated for each patient. The anterior axillary boost field and IMRT resulted in superior dose coverage compared with PAB. Namely, treatment volumes that received 105%, 80%, and 30% of prescribed dose for IMRT plans were significantly less than those for the anterior axillary boost plans, which were significantly less than PAB. For PAB and anterior axillary boost plans, there was a linear correlation between treatment volume receiving 105% of prescribed dose and maximum target depth. Furthermore, the IMRT technique resulted in better lung sparing and dose conformity to the target than anterior axillary boost, which again was significantly better than PAB. The maximum cord dose for IMRT was small, but higher than for the other two techniques. More monitor units were required to deliver the IMRT plan than the PAB plan, which was more than the anterior axillary boost plan. The PAB technique is not optimal for treatment of AX lymph nodes in an SCV field. We conclude that CT treatment planning with dose optimization around delineated target volumes should become standard for radiation treatments of supraclavicular and AX lymph nodes.

    To evaluate the use of a pinpoint irradiation technique followed by nonablative fractional technique in treatment of traumatic scars. Thirteen patients with traumatic sacrs were treated with pinpoint technique of CO2 laser using traditional headpiece activating laser at a frequency (50 Hz) to deliver pulsed mode with power of 1 W using the focusing technique followed by 3-5 passes of the nonablative 1540 nm fractional Er:glass laser. An independent physician evaluator assessed the treatment outcomes using Vancouver scar scale (VSS) and 5-point grading scale (grade 0, no improvement; grade 1, 1-25%; grade 2, 26-50%; grade 3, 51-75%; grade 4, 76-100% improvement). After the final treatment, average percentage changes of VSS were 41.5%. Improvement was evident in terms of vascularity, pigmentation, and height, while insignificant in terms of Pliability. Based on physician's global assessment, mean grade of 2.5 was achieved. Patient's subjective satisfaction scores paralleled the physician's objective evaluation. Pinpoint irradiation technique by CO2 laser followed by nonablative fractional laser is a safe and effective modality in treatment of scars.

    2004-01-01

    Field experiments assessing UV-B effects on plants have been conducted using two contrasting techniques: supplementation of solar UV-B with radiation from fluorescent UV lamps and the exclusion of solar UV-B with filters. We compared these two approaches by growing lettuce and oat simultaneously under three conditions: UV-B exclusion, near-ambient UV-B (control) and UV-B supplementation (simulating a 30% ozone depletion). This permitted computation of "solar UV-B" and "supplemental UV-B" effects. Microclimate and photosynthetically active radiation were the same under the two treatments and the control. Excluding UV-B changed total UV-B radiation more than did supplementing UV-B, but the UV-B supplementation contained more "biologically effective" shortwave radiation. For oat, solar UV-B had a greater effect than supplemental UV-B on main shoot leaf area and main shoot mass, but supplemental UV-B had a greater effect on leaf and tiller number and UV-B-absorbing compounds. For lettuce, growth and stomatal density generally responded similarly to both solar UV-B and supplemented UV-B radiation, but UV-absorbing compounds responded more to supplemental UV-B, as in oat. Because of the marked spectral differences between the techniques, experiments using UV-B exclusion are most suited to assessing effects of present-day UV-B radiation, whereas UV-B supplementation experiments are most appropriate for addressing the ozone depletion issue.

    Eckerson, Joan M.

    Obesity has reached what may be considered epidemic proportions in the United States, not only for adults but for children. Because of the medical implications and health care costs associated with obesity, as well as the negative social and psychological impacts, many individuals turn to nonprescription nutritional weight loss supplements hoping for a quick fix, and the weight loss industry has responded by offering a variety of products that generates billions of dollars each year in sales. Most nutritional weight loss supplements are purported to work by increasing energy expenditure, modulating carbohydrate or fat metabolism, increasing satiety, inducing diuresis, or blocking fat absorption. To review the literally hundreds of nutritional weight loss supplements available on the market today is well beyond the scope of this chapter. Therefore, several of the most commonly used supplements were selected for critical review, and practical recommendations are provided based on the findings of well controlled, randomized clinical trials that examined their efficacy. In most cases, the nutritional supplements reviewed either elicited no meaningful effect or resulted in changes in body weight and composition that are similar to what occurs through a restricted diet and exercise program. Although there is some evidence to suggest that herbal forms of ephedrine, such as ma huang, combined with caffeine or caffeine and aspirin (i.e., ECA stack) is effective for inducing moderate weight loss in overweight adults, because of the recent ban on ephedra manufacturers must now use ephedra-free ingredients, such as bitter orange, which do not appear to be as effective. The dietary fiber, glucomannan, also appears to hold some promise as a possible treatment for weight loss, but other related forms of dietary fiber, including guar gum and psyllium, are ineffective.

  7. To supplement or not to supplement: a metabolic network framework for human nutritional supplements.

    Full Text Available Flux balance analysis and constraint based modeling have been successfully used in the past to elucidate the metabolism of single cellular organisms. However, limited work has been done with multicellular organisms and even less with humans. The focus of this paper is to present a novel use of this technique by investigating human nutrition, a challenging field of study. Specifically, we present a steady state constraint based model of skeletal muscle tissue to investigate amino acid supplementation's effect on protein synthesis. We implement several in silico supplementation strategies to study whether amino acid supplementation might be beneficial for increasing muscle contractile protein synthesis. Concurrent with published data on amino acid supplementation's effect on protein synthesis in a post resistance exercise state, our results suggest that increasing bioavailability of methionine, arginine, and the branched-chain amino acids can increase the flux of contractile protein synthesis. The study also suggests that a common commercial supplement, glutamine, is not an effective supplement in the context of increasing protein synthesis and thus, muscle mass. Similar to any study in a model organism, the computational modeling of this research has some limitations. Thus, this paper introduces the prospect of using systems biology as a framework to formally investigate how supplementation and nutrition can affect human metabolism and physiology.

    For the head-and-neck cancer bilateral irradiation, intensity-modulated radiation therapy (IMRT) is the most reported technique as it enables both target dose coverage and organ-at-risk (OAR) sparing. However, during the last 20 years, three-dimensional conformal radiotherapy (3DCRT) techniques have been introduced, which are tailored to improve the classic shrinking field technique, as regards both planning target volume (PTV) dose conformality and sparing of OAR's, such as parotid glands and spinal cord. In this study, we tested experimentally in a sample of 13 patients, four of these advanced 3DCRT techniques, all using photon beams only and a unique isocentre, namely Bellinzona, Forward-Planned Multisegments (FPMS), ConPas, and field-in-field (FIF) techniques. Statistical analysis of the main dosimetric parameters of PTV and OAR's DVH's as well as of homogeneity and conformity indexes was carried out in order to compare the performance of each technique. The results show that the PTV dose coverage is adequate for all the techniques, with the FPMS techniques providing the highest value for D95%; on the other hand, the best sparing of parotid glands is achieved using the FIF and ConPas techniques, with a mean dose of 26 Gy to parotid glands for a PTV prescription dose of 54 Gy. After taking into account both PTV coverage and parotid sparing, the best global performance was achieved by the FIF technique with results comparable to that of IMRT plans. This technique can be proposed as a valid alternative when IMRT equipment is not available or patient is not suitable for IMRT treatment.

    The volumetric modulated arc therapy (VMAT) technique, in the form of RapidArc, is widely used to treat prostate cancer. The full-single arc (f-SA) technique in RapidArc planning for prostate cancer treatment provides efficient treatment, but it also delivers a higher radiation dose to the rectum. This study aimed to compare the dosimetric results from the new partial-single arc (p-SA) technique with those from the f-SA technique in RapidArc planning for prostate cancer treatment. In this study, 10 patients with low-risk prostate cancer were selected. For each patient, two sets of RapidArc plans (f-SA and p-SA) were created in the Eclipse treatment planning system. The f-SA plan was created using one ful arc, and the p-SA plan was created using planning parameters identical to those of the f-SA plan but with anterior and posterior avoidance sectors. Various dosimetric parameters of the f-SA and p-SA plans were evaluated and compared for the same target coverage and identical plan optimization parameters. The f-SA and p-SA plans showed an average difference of ±1% for the doses to the planning target volume (PTV), and there were no clear differences in dose homogeneity or plan conformity. In comparison to the f-SA technique, the p-SA technique reduced the doses to the rectum by approximately 6.1% to 21.2%, to the bladder by approximately 10.3%to 29.5%, and to the penile bulb by approximately 2.2%. In contrast, the dose to the femoral heads, the integral dose, and the number of monitor units were higher in the p-SA plans by approximately 34.4%, 7.7%, and 9.2%, respectively. In conclusion, it is feasible to use the p-SA technique for RapidArc planning for prostate cancer treatment. For the same PTV coverage and identical plan optimization parameters, the p-SA technique is better in sparing the rectum and bladder without compromising plan conformity or target homogeneity when compared to the f-SA technique.

    Excessive gingival display (EGD) is a condition in which an overexposure of the maxillary gingiva (>3 mm) is present during smiling. The proper diagnosis and determination of its etiology are essential for the selection of the right treatment modality. Different techniques have been used in cases of hyperactive upper lip: botulinum toxin injections, lip elongations with rhinoplasties, lip muscle detachments, myotomies, and lip repositions. This report presents a case of a young woman with an EGD larger than 10 mm during smiling caused by altered passive eruption, vertical maxillary excess, and a hyperactive upper lip that was treated with a modified lip repositioning technique and laser gingivectomy because she strongly refused orthognathic surgical treatment. A novel addition to the technique is proposed, a reversible trial accomplished just by applying sutures on the borders of the future split-thickness flap, marked using diode laser, before starting the flap incision.

    Healthcare waste should be managed carefully because of infected, pathological, etc. content especially in developing countries. Applied management systems must be the most appropriate solution from a technical, environmental, economic and social point of view. The main objective of this study was to analyse the current status of healthcare waste management in Turkey, and to investigate the most appropriate treatment/disposal option by using different decision-making techniques. For this purpose, five different healthcare waste treatment/disposal alternatives including incineration, microwaving, on-site sterilization, off-site sterilization and landfill were evaluated according to two multi-criteria decision-making techniques: analytic network process (ANP) and ELECTRE. In this context, benefits, costs and risks for the alternatives were taken into consideration. Furthermore, the prioritization and ranking of the alternatives were determined and compared for both methods. According to the comparisons, the off-site sterilization technique was found to be the most appropriate solution in both cases.

    The influence of organ volume sampling, lateral scatter inclusion, and the selection of objectives and constraints on the inverse treatment planning process with a commercial treatment planning system is investigated and suitable parameters are identified for an inverse treatment planning replacement of a clinical forward planning technique for prostate cancer. For the beam geometries of the forward technique, a variable set of parameters is used for the calculation of dose from pencil beams. An optimal set is identified after the evaluation of optimized plans that correspond to different sets of pencil-beam parameters. This set along with a single, optimized set of objectives and constraints is used to perform inverse planning on ten randomly selected patients. The acceptability of the resulting plans is verified by comparisons to the clinical ones calculated with the forward techniques. For the particular commercial treatment planning system, the default values of the pencil beam parameters are found adequate for inverse treatment planning. For all ten patients, the optimized, single set of objectives and constraints results in plans with target coverage comparable to that of the forward plans. Furthermore inverse treatment planning reduces the overall mean rectal and bladder doses by 4.8% and 5.8% of the prescription dose respectively. The study indicates that (i) inverse treatment planning results depend implicitly on the sampling of the dose distribution, (ii) inverse treatment planning results depend on the method used by the dose calculation model to account for scatter, and (iii) for certain sites, a single set of optimization parameters can be used for all patient plans.

    To investigate the clinical application value of the 3D printing technique in the treatment of basilar invagination and atlantoaxial dislocation. From January 2013 to September 2013, 10 patients with basilar invagination and atlantoaxial dislocation needing posterior fixation undertook 3D printing modes at the Department of Neurosurgery in PLA General Hospital. The 1:1 size models were established from skull base to C4 level with different colors between bone structures and vertebral arteries. The simulation of screw insertion was made to investigate the fixation plan and ideal entry point to avoid vertebral artery injury. After obtaining the individual screw insertion data in 3D printing modes, the according surgical operations were performed. The actual clinical results and virtual screw data in 3D printing mode were compared with each other. The 3D printing modes revealed that all the 10 patients had the dysplasia or occipitalized C1 posterior arch indicating C1 posterior arch screw implantation was not suitable. C1 lateral masses were chosen as the screws entry points. C2 screws were designed individually based on the 3D printing modes as follows: 3 patients with aberrant vertebral artery or narrow C2 pedicle less than 3.5 mm were not suitable for pedicle screw implantation. Among the 3 patients, 1 was fixed with C2 laminar screw, and 1 with C2-3 transarticular screw and 1 with C3 pedicle screw (also combined with congenital C2-3 vertebral fusion). Two patients with narrow C2 pedicle between 3.5 and 4mm were designed to choose pedicle screw fixation after 3D printing mode evaluation. One patient with C1 lateral mass vertically dislocated axis was planned with C1-2 transarticular screw fixation. All the other patients were planned with C2 pedicle screws. All the 10 patients had operation designed as the 3D printing modes schemes. The follow-up ranged from 12 to 18 months and all the patients recovered from the clinical symptoms and the bony fusion attained to

    For various soft tissues (e.g., liver, breast, etc.), we are developing the ultrasonic strain measurement-based mechanical properties (shear modulus, visco-shear modulus, etc.) reconstruction/imaging technique. To clarify the limitation of our quantitative reconstruction/imaging technique as a diagnostic tool for differentiating malignancies, together with improving the spatial resolution and the dynamic range we are collecting the clinical reconstruction image data. Furthermore, we are applying our technique as a monitoring technique for the effectiveness of chemical therapy (e.g., anticancer drug, ethanol, etc.), thermal therapy (e.g., micro, and rf electromagnetic wave, HIFU, LASER, etc.), and cryotherapy. As soft tissues are deformed in 3-D space due to externally situated quasi-static and/or low frequency mechanical sources, multidimensional signal processing improves strain measurement accuracy and reduces inhomogeneity-dependent modulus reconstruction artifacts. These have been verified by us through simulations and phantom/animal in vitro experiments. Briefly, here we discuss the limitations of low dimensional signal processing. Moreover, we exhibit the superiority both on differential diagnosis for these human in vivo malignancies and monitoring for these therapies of our quasi-real time imaging (using conventional US equipment) to conventional B-mode imaging. Our technique is available as a clinical visualization technique both for diagnosis and treatment, and monitored mechanical properties data can also be effectively utilized as the measure for controlling the therapy, i.e., the exposure energy, the foci, the exposure interval, etc. In the near future, suitable combination of various simple and low-invasive therapy techniques with our imaging technique will open up a new clinical style allowing diagnosis and the subsequently immediate treatment. This must substantially reduce the total medical expenses.

    Full Text Available Purpose: This work proposes and compares two 3D global evaluation methods for assessing the alteration of calculated dose distributions when treatment planning system algorithms or irradiation techniques is modified in radiation therapy. Methods: The global analysis is based on gamma index (γ proposed by Low et al.1 and Chi (χ index proposed by Bakai et al.2. The γ and χ values are signed in order to identify the over and under estimating dosage. The 3D maps, the cumulative Gamma Voxels Histograms (GVHs and Chi Voxels Histograms (CVHs were generated using two software. The γ and χ criteria were set to 3 mm for the distance to agreement and 3% for dose. Pearson's Chi-squared test was applied to assess the statistically significance between GVHs and CVHs. We illustrated this method for the change of dose calculation algorithms for lung cancer, and the change of irradiation techniques for breast cancer. For each patient, 2 treatment plans were generated. For the example of change of dose calculation algorithms, a plan 1 was calculated using Pencil Beam Convolution (PBC algorithm and a plan 2 was calculated using Modified Batho method (PBC-MB. For the example of change of irradiation technique, a plan 1 was calculated using Source Skin Distance SSD technique and a plan 2 was calculated using a single isocenter technique. Results: The 3D analysis based on γ and χ indexes showed a significant effect on the dosimetric representation in the lung cancer when we change the PBC algorithm to PBC-MB method. The comparison between the two irradiation techniques showed that the single isocenter technique produces a better dose distribution for the treatment of breast cancer. Pearson's Chi-squared test showed that there was no statistically significance between GVHs and CVHs generated by γ and χ indexes, (p > 0.05. The global analysis using 3D for γ and χ indexes confirmed the results obtained from dosimetric analysis. Conclusion: The methods

    No studies to date have examined the effect of counselor techniques on smoking cessation over the course of treatment. To address this gap, we examined the degree to which the use of specific Acceptance and Commitment Therapy (ACT) counseling techniques in a given session predicted smoking cessation reported at the next session. The data came from the ACT arm of a randomized controlled trial of a telephone-delivered smoking cessation intervention. Trained raters coded 139 counseling sessions across 44 participants. The openness, awareness and activation components of the ACT model were rated for each telephone counseling session. Multilevel logistic regression models were used to estimate the predictive relationship between each component during any given telephone session and smoking cessation at the following telephone session. For every 1-unit increase in counselors' use of openness and awareness techniques there were 42% and 52% decreases in the odds of smoking at the next counseling session, respectively. However, there was no significant predictive relationship between counselors' use of activation techniques and smoking cessation. Overall, results highlight the theoretical and clinical value of examining therapists' techniques as predictors of outcome during the course of treatment. Published by Elsevier Ltd.

Group I included 12 patients treated with Lindholm augmentation technique, whereas group II included 12 patients treated with modified Kessler end-to-end repair. Thereafter, these patients had postoperative management with a below-knee-cast for three weeks. The physioteraphy was initiated immediately after the cast was removed. Full weight bearing was allowed after five weeks postoperatively in the both groups. Two patients had reruptures in group II, whereas group I had prolonged operative time significantly. The patients with reruptures underwent reoperations and at the most final follow-up, it was observed that they could not resume to sporting activities. The other objective and subjective results were similar between two groups. Because of quite high rerupture rate in the group of patients treated with nonaugmentation technique, we favor functional postoperative treatment with early ankle movement in the patients treated with augmentation technique for the management of acute rupture of the Achilles tendon

    Breast, chest wall, and regional nodal irradiation have been associated with an improved outcome in high-risk breast cancer patients. Complex treatment planning is often utilized to ensure complete coverage of the target volume while minimizing the dose to surrounding normal tissues. The 2 techniques evaluated in this report are the partially wide tangent fields (PWTFs) and the 4-field photon/electron combination (the modified "Kuske Technique"). These 2 techniques were evaluated in 10 consecutive breast cancer patients. All patients had computerized tomographic (CT) scans for 3D planning supine on a breast board. The breast was defined clinically by the physician and confirmed radiographically with radiopaque bebes. The resulting dose-volume histograms (DVHs) of normal and target tissues were then compared. The deep tangent field with blocks resulted in optimal coverage of the target and the upper internal mammary chain (IMC) while sparing of critical and nontarget tissues. The wide tangent technique required less treatment planning and delivery time. We compared the 2 techniques and their resultant DVHs and feasibility in a busy clinic.

    The ancient system of Kundalini yoga includes a vast array of meditation techniques and many were discovered to be specific for treating the psychiatric disorders as we know them today. One such technique was found to be specific for treating obsessive-compulsive disorder (OCD), the fourth most common psychiatric disorder, and the tenth most disabling disorder worldwide. Two published clinical trials are described here for treating OCD using a specific Kundalini yoga protocol. This OCD protocol also includes techniques that are useful for a wide range of anxiety disorders, as well as a technique specific for learning to manage fear, one for tranquilizing an angry mind, one for meeting mental challenges, and one for turning negative thoughts into positive thoughts. Part of that protocol is included here and published in detail elsewhere. In addition, a number of other disorder-specific meditation techniques are included here to help bring these tools to the attention of the medical and scientific community. These techniques are specific for phobias, addictive and substance abuse disorders, major depressive disorders, dyslexia, grief, insomnia and other sleep disorders.

    Full Text Available Objective : Compare the interlaminar blocking technique with the transforaminal blocking, with regard to pain and the presence or absence of complications. Methods : Prospective, descriptive and comparative, double-blind, randomized study, with 40 patients of both sex suffering from sciatic pain due to central-lateral or foraminal disc herniation, who did not respond to 20 physiotherapy sessions and had no instability diagnosed on examination of dynamic radiography. The type of blocking, transforaminal or interlaminar, to be performed was determined by draw. Results : We evaluated 40 patients, 17 males, mean age 49 years, average VAS pre-blocking of 8.85, average values in transforaminal technique in 24 hours, 7, 21, and 90 days of 0.71, 1.04, 2.33 and 3.84, respectively; the average VAS post-blocking for interlaminar technique was 0.89, 1.52, 3.63 and 4.88. The techniques differ only in the post-blocking period of 21 days and overall post-blocking, with significance of p=0.022 and p=0.027, respectively. Conclusion : Both techniques are effective in relieving pain and present low complication rate, and the transforaminal technique proved to be the most effective.

    Helical Tomotherapy (HT) plans were used to create two RapidPlan knowledge-based (KB) models to generate plans with different techniques and to guide the optimization in a different treatment planning system for prostate plans. Feasibility and performance of these models were evaluated. two sets of 35 low risk (LR) and 30 intermediate risk (IR) prostate cancer cases who underwent HT treatments were selected to train RapidPlan models. The KB predicted constraints were used to perform new 20KB plans using RapidArc technique (KB-RA) (inter-technique validation), and to optimise 20 new HT (KB-HT) plans in the Tomoplan (inter-system validation). For each validation modality, KB plans were benchmarked with the manual plans created by an expert planner (EP). RapidPlan was successfully configured using HT plans. The KB-RA plans fulfilled the clinical dose-volume requirements in 100% and 92% of cases for planning target volumes (PTVs) and organs at risk (OARs), respectively. For KB-HT plans these percentages were found to be a bit lower: 90% for PTVs and 86% for OARs. In comparison to EP plans, the KB-RA plans produced higher bladder doses for both LR and IR, and higher rectum doses for LR. KB-HT and EP plans produced similar results. RapidPlan can be trained to create models by using plans of a different treatment modality. These models were suitable for generating clinically acceptable plans for inter-technique and inter-system applications. The use of KB models based on plans of consolidated technique could be useful with a new treatment modality. Copyright © 2017 Associazione Italiana di Fisica Medica. Published by Elsevier Ltd.

    Background Aneurysms with wide-necked or a large neck/fundus ratio, especially located on an arterial bifurcation or a small artery, are challenges for interventional neuroradiologist because of the risk of coil migration or coil protrusion into the parent vessels. Our study was designed to improve the efficacy and safety of the "remodeling technique" with the HyperForm balloon for these difficult aneurysms and was confirmed by a follow-up result. Methods From June 2004 to September 2006, forty-two patients(20 men, 22 women)with wide-necked or large neck/fundus ratio aneurysms were treated by using the"remodeling technique"with the HyperForm balloon. Results Forty wide-necked aneurysms were successfully treated with the HyperForm balloon remodeling technique with only two failed cases. Final results consisted of total occlusion in 34 cases(80.9%), subtotal in 4 (9.5%) and incomplete in 2(4.8%). One aneurysmal rupture occurred, but no clinical consequence was shown. No thromboembolic events were observed during treatment. Final angiographic follow-up time ranged from 3 to 18 months. Conclusions The "remodeling technique" with the HyperForm balloon is a very useful tool in the treatment of wide-necked or unfavorable neck/fundus ratio intracranial aneurysms-located on an arterial bifurcation or a small artery and, especially, located on the bifurcation of a large artery and a small one. In our experience, this technique provided a safe and efficient treatment for difficult aneurysms when the standard remodeling technique might have failed.

    Indium-tin-oxide(ITO) films were prepared on the quarts glass by sol-gel technique. Effects of different heat treatment temperatures and cooling methods on the morphological, optical and electrical properties of ITO films were measured by TG/DTA, IR, XRD, SEM, UV-VIS spectrometer and four-probe apparatus. It is found that the crystallized ITO films exhibit a polycrystalline cubic bixbyite structure. The heat treatment process has significant effects on the morphological, optical and electrical properties of ITO films. Elevating the heat treatment temperature can perfect the crystallization process of ITO films, therefore the optical and electrical properties of ITO films are improved. But the further increasing of heat treatment temperature results in the increment of ITO films' resistivity. Compared with ITO films elaborated by furnace cooling, those prepared through air cooling have following characteristics as obviously decreased crystalline size, deeply declined porosity, more compact micro-morphology, improved electrical property and slightly decreased optical transmission.

    Arthrofibrosis of the knee is a surgical complication that can limit range of motion, inhibit muscle activity, and decrease patient function. Optimal conservative treatment has not been well established in the literature, leaving a clinician with limited evidence for treatment planning. Described here is part of the rehabilitative course of care for a patient with arthrofibrotic limitations after a mid-substance patellar tendon repair with augmentation. Marked limitations in knee flexion range of motion and quadriceps activity were addressed using the Graston Technique to deal with soft-tissue adhesions; traditional physical therapy care was also provided. Clear improvement in range of motion and quadriceps activity and function was noted over the course of 5 treatments during 1 month. Treatment process and clinical reasoning are offered to promote understanding and to facilitate future inquiry.

    @@ Bifurcation lesions are still technically challenging even in the era of modern stents.1 High incidence of restenosis both in main vessel and side branch limits the long-term prognosis although several kinds of techniques have been identified to be successful for coronary bifurcations.2-5 Reports have demonstrated the main reason for higher incidence of ostial side branch even though drug-eluting stent used in side vessel lies in that there were gaps in metal coverage and drug application.6-9 Therefore, new technique ensuring complete vessel scaffolding without gaps in drug delivery at the bifurcation is crush technique which is similar to other techniques including T- and Y- stenting still needing postdilatation of kissing balloon angioplasty to expand the stent fully in the ostial side branch and to prevent stent distortion in main vessel.10 As a result, kissing balloon angioplasty is a key step to improve the final result and to reduce the restenosis after stenting bifurcation lesions. However, kissing angioplasty is difficult to be underwent or impossible because operators usually fail to rewire two layers of metal strut, which would result in suboptimal stent deployment, a main reason of high incidence of restenosis, and acute- or-late-thrombosus. The present study reports modified DK crush technique improving success rate of kissing balloon angioplasty under the guidance of intravascular ultrasound (IVUS).

    2013-07-01

    Full Text Available The study aimed at determination of the cecostomy technique that will preserve the long-term maximal diameter of the created fistula. The subjects of the study were 79 newly born cattle and buffalo calves suffered from atresia coli, recti and ani. The calves were grouped into four groups for evaluation of incisional and herniation cecostomy techniques either on the right or left flank. With each technique, 4 cm diameter permanent fistula was created and evaluated at the 1stweek, and 1st, 4th and 8th months post-surgery. Both of the short and long-term complications were recorded and managed conservatively. Follow up could be achieved for 45 calves only and all of them showed stunted growth. The results revealed wider stoma in the calves operated by herniation technique, and in those operated on the right flank, moreover the operated cattle calves had wider stoma than buffalo calves. It is concluded that the right flank herniation technique has a beneficial effect on long-term preserving of a wider diameter of the created fistula.

    This study aimed to evaluate the short-term efficiency of mandibular manipulation technique combined with exercise therapy and splint treatment of acute anterior TMJ disc displacement without reduction (ADDW), and TMJ disc-condyle relationship by magnetic resonance imaging (MRI). Forty-four patients (37 females, 7 males) were diagnosed as acute ADDW and confirmed by MRI. All patients underwent mandibular manipulation, combined with exercise therapy, including jaw movement exercise, stabilization exercise, disc reposition exercise, and splint treatment. Anterior repositioning splint was wore only at night during sleep, while the mandible was kept in rest position during the day. The treatment was continued for 2 weeks. The baseline and endpoint outcome assessment measures were maximum active mouth opening, visual analogue scale (VAS) score of TMJ pain. Consecutive MRI was performed 1~3 months after treatment. SPSS 17.0 software package was used for statistical analysis. Two weeks after treatment, the patients' maximum active mouth opening increased from(22.6±6.1) mm to (43.9±3.3) mm, VAS score of pain decreased from 3.6±1.5 to 0.7±0.25. After treatment of 4.6±4.7 weeks on average, 20 patients (46%) displayed normal dis-condyle relationship, 16 patients(36%) had displacement with reduction, and 8 patients(18%) had displacement without reduction on MRI. Mandibular manipulation technique combined with exercise therapy and splint treatment seems to be useful in the treatment of anterior TMJ disc displacement with reduction, which can help to maintain the complete anatomic disc-condyle relationship.

    Eccentric activities are an important component of physical conditioning and everyday activities. Delayed onset muscle soreness (DOMS) can result from strenuous eccentric tasks and can be a limiting factor in motor performance for several days after exercise. An efficacious method of treatment for DOMS would enhance athletic performance and hasten the return to activities of daily living. The purpose of this study was to identify a treatment method which could assist in the recovery of DOMS. In the selection of treatment methods, emphasis was directed toward treatments that could be rendered independently by an individual, therefore making the treatment valuable to an athletic trainer in team setting. DOMS was induced in 70 untrained volunteers via 15 sets of 15 eccentric contractions of the forearm extensor muscles on a Lido isokinetic dynamometer. All subjects performed a pilot exercise bout for a minimum of 9 weeks before data collection to assure that DOMS would be produced. Data were collected on 15 dependent variables: active and passive wrist flexion and extension, forearm girth, limb volume, visual analogue pain scale, muscle soreness index, isometric strength, concentric and eccentric wrist total work, concentric and eccentric angle of peak torque. Data were collected on six occasions: pre- and post-induced DOMS, 20 minutes after treatment, and 24, 48, and 72 hours after treatment. Subjects were randomly assigned to 1 of 7 groups (6 treatment and 1 control). Treatments included a nonsteroidal anti-inflammatory drug, high velocity concentric muscle contractions on an upper extremity ergometer, ice massage, 10-minute static stretching, topical Amica montana ointment, and sublingual A. montana pellets. A 7 × 6 ANOVA with repeated measures on time was performed on the delta values of each of the 15 dependent variables. Significant main effects (p < .05) were found for all of the dependent variables on time only. There were no significant differences between

  2. Cardiovascular Effects of Calcium Supplements

    Directory of Open Access Journals (Sweden)

    Ian R. Reid

    2013-07-01

    Full Text Available Calcium supplements reduce bone turnover and slow the rate of bone loss. However, few studies have demonstrated reduced fracture incidence with calcium supplements, and meta-analyses show only a 10% decrease in fractures, which is of borderline statistical and clinical significance. Trials in normal older women and in patients with renal impairment suggest that calcium supplements increase the risk of cardiovascular disease. To further assess their safety, we recently conducted a meta-analysis of trials of calcium supplements, and found a 27%–31% increase in risk of myocardial infarction, and a 12%–20% increase in risk of stroke. These findings are robust because they are based on pre-specified analyses of randomized, placebo-controlled trials and are consistent across the trials. Co-administration of vitamin D with calcium does not lessen these adverse effects. The increased cardiovascular risk with calcium supplements is consistent with epidemiological data relating higher circulating calcium concentrations to cardiovascular disease in normal populations. There are several possible pathophysiological mechanisms for these effects, including effects on vascular calcification, vascular cells, blood coagulation and calcium-sensing receptors. Thus, the non-skeletal risks of calcium supplements appear to outweigh any skeletal benefits, and are they appear to be unnecessary for the efficacy of other osteoporosis treatments.

    The purpose of this study was to describe alternative endovascular (EV) techniques and assess their feasibility and efficacy in minimizing failure rates in limb salvage for the treatment of complex below-the knee (BTK) occlusions that could not be crossed with a conventional antegrade access. Between December 2007 and November 2010, 1,035 patients (557 male) underwent EV treatment for critical limb ischemia in our institution. In 124 (12% [83 male], mean age 68.2 {+-} 0.5 years) patients, transfemoral antegrade revascularization attempt failed, and an alternative approach was used. Follow-up was performed at 1 and 6 months. Results were compared with 56 patients treated between November 2002 and November 2007, in whom conventional technique was unsuccessful and unconventional techniques were not adopted. Technical success was achieved in 119 (96%) patients. The limb-salvage rates were 96.8% and 83% at 1- and 6-month follow-up, respectively. Sixteen (12.9%) and 33 (26.6%) patients underwent reintervention at 1- and 6-month follow-up, respectively. Transcutaneous oxygen tension increased at 1 month (44.7 {+-} 1.1 vs. 15.7 {+-} 0.8 mmHg; p < 0.001) and remained stable at follow-up. Twenty (16.1%) patients required major amputation. Thirteen (10.4%) patients died during follow-up. In our previous experience, percutaneous transluminal angioplasty failure, amputation, and death rates were 10.9, 39.2, and 23.2%, respectively. Alternative techniques allowed a significant decrease of major amputation and death rates (p = 0.0001 and p = 0.02, respectively). The use of alternative techniques seems feasible in case of a failed antegrade BTK revascularization attempt and could minimize failure rates in the treatment of complex occlusions while providing satisfying clinical success rates at 6 months.

    Full Text Available Background: Children with osteogenesis imperfecta (OI can suffer from frequent fractures and limb deformities, resulting in impaired ambulation. Osteopenia and thin cortices complicate orthopedic treatment in this group. This study evaluates the clinical results of a bone splint technique for the treatment of lower limb deformities in children with type I OI. The technique consists of internal plating combined with cortical strut allograft fixation. Materials and Methods: We prospectively followed nine children (five boys, four girls with lower limb deformities due to type I OI, who had been treated with the bone splint technique (11 femurs, four tibias between 2003 and 2006. The fracture healing time, deformity improvement, ambulation ability and complications were recorded to evaluate treatment effects. Results: At the time of surgery the average age in our study was 7.7 years (range 5-12 years. The average length of followup was 69 months (range 60-84 months. All patients had good fracture healing with an average healing time of 14 weeks (range 12-16 weeks and none experienced further fractures, deformity, or nonunion. The fixation remained stable throughout the procedure in all cases, with no evidence of loosening or breakage of screws and the deformity and mobility significantly improved after surgery. Of the two children confined to bed before surgery, one was able to walk on crutches and the other needed a wheelchair. The other seven patients could walk without walking aids or support like crutches. Conclusions: These findings suggest that the bone splint technique provides good mechanical support and increases the bone mass. It is an effective treatment for children with OI and lower limb deformities.

    The most essential development in endovascular stroke treatment (EST) was the shift from intra-arterial thrombolysis to endovascular thrombectomy with dedicated thrombectomy devices, most notably the introduction of stent-retrievers. We evaluated procedural and clinical effectiveness and safety of different EST techniques over time. We retrospectively analyzed EST cases that were treated by the same interventionalist before (n=36) and after (n=50) stent-retrievers were established as the treatment device of first choice. EST techniques in the first cohort comprised intra-arterial thrombolysis (n=24), manual thrombus aspiration (n=15), the use of the Penumbra thrombectomy system (n=13) and the Phenox clot retriever (n=3), intracranial stenting (n=10), and EST with stent-retrievers as a salvage procedure (n=11). In the second cohort, EST with stent-retrievers was the treatment option of first choice (n=47). Intra-arterial thrombolysis (n=15) and stenting of the occluded vessel (n=1) were performed, whenever EST with stent-retrievers failed. In both cohorts, revascularization rates (TICI ≥2b) were high (91.7% and 86.0%, respectively). A significantly lower number of interventional techniques per case were required in the second cohort (mean ± SD, 1.4±0.5 vs. 2.1±0.9, P<0.001). Recanalization was achieved almost twice as fast in the second cohort (85 vs. 163 minutes on average, P<0.001). The rate of patients achieving good functional outcome (mRS ≤2) was higher in the second cohort (40.0% vs. 22.2%, P=0.083). Our findings imply that when stent-retrievers were established as first-line the treatment device a significantly lower number of interventional techniques per case were required and recanalization was achieved almost twice as fast.

    Background Moderate acute malnutrition is a major public health problem affecting children from low- and middle-income countries. Lipid nutrient supplements have been proposed as a nutritional intervention for its treatment. Objectives To evaluate the effectiveness and safety of LNS for the treatment of MAM in infants and children 6 to 59 months of age. Study design Systematic review of randomized-controlled trials and controlled before-after studies. Results Data from nine trials showed that use of LNS, in comparison to specially formulated foods, improved the recovery rate (RR 1.08; 95% CI 1.02–1.14, 8 RCTs, 8934 participants, low quality evidence); decreased the chances of no recovery (RR 0.70; 95% CI 0.58–0.85, 7 RCTs, 8364 participants, low quality evidence) and the risk of deterioration into severe acute malnutrition (RR 0.87; 95% CI 0.73–1.03, 6 RCTs, 6788 participants, low quality evidence). There was little impact on mortality (RR 0.94, 95% CI 0.54–1.52, 8 RCTs, 8364 participants, very-low- quality evidence) or default rate (RR 1.32; 95% CI 0.73–2.4, 7 studies, 7570 participants, low quality evidence). There was improvement in weight gain, weight-for-height z-scores, height-for-age z-scores and mid-upper arm circumference. Subset analyses suggested higher recovery rates with greater amount of calories provided and with ready-to-use therapeutic foods, in comparison to ready-to-use supplementary foods. One study comparing LNS with nutritional counselling (very low quality evidence) showed higher chance of recovery, lower risk of deteriorating into severe acute malnutrition and lower default rate, with no impact on mortality, and no recovery. Conclusions Evidence restricted to the African regions suggests that LNS may be slightly more effective than specially formulated fortified foods or nutritional counselling in recovery from MAM, lowering the risk of deterioration into SAM, and improving weight gain with little impact on mortality or default

    Full Text Available Abstract Background Environmental factors, particularly commensal bacteria in the gastrointestinal tract, may be involved in the pathogenesis of rheumatoid arthritis (RA. The aim of this study was to evaluate whether natural milk antibodies against a wide spectrum of pathogenic enteromicobes and their toxins modify the disease activity in RA. Methods Twenty patients with RA, whose disease activity was uncontrolled by authentic medications due to drug resistance, complications and/or risk factors were treated for 3 months with an oral administration of a whey protein concentrate (WPC containing high levels of natural milk antibodies. Eighteen background-matched RA patients, not supplemented with milk antibody adjunct, were used as controls. Results Statistically significant reduction of arthritis symptoms and improvement of intestinal disorders were observed only in the test group: effective in 8 (44%, possibly effective in 2 (12% and not effective in 8 (44% of 18 patients treated (2 patients withdrew based on an ad hoc "evaluation point", the sum of variables that are improved more than 20% among the 8 core variables used for the American College of Rheumatology (ACR response criteria. This disease modifying effect of the WPC disappeared upon cessation of treatment, but was reappeared upon reintroduction of it. Importantly, 7 of 8 non-responders carry DR15 haplotype (DRB1-1501 and 1502, whereas only 1 of 7 responders was DR15 positive (risk ratio: 6.1. Furthermore, the pre-clinical serum anti-LPS and anti-type II collagen antibody levels in the responders were higher or tended to be higher than those in the non-responders, suggesting that there are 2 sub-types of RA based on an interaction between gastrointestinal pathogens and MHC class II haplotypes. Conclusions The natural milk antibody preparation containing high levels antibodies against pathogenic enteromicrobes and their toxins seems to be effective in a certain RA subset, and deserves

    The objective of this study was to compare the functional assessments of arthroscopy and open repair for treating Bankart lesion in traumatic anterior shoulder instability. Fifty adult patients, aged less than 40 years, with traumatic anterior shoulder instability and the presence of an isolated Bankart lesion confirmed by diagnostic arthroscopy were included in the study. They were randomly assigned to receive open or arthroscopic treatment of an isolated Bankart lesion. In all cases of both groups, the lesion was repaired with metallic suture anchors. The primary outcomes included the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire. After a mean follow-up period of 37.5 months, 42 patients were evaluated. On the DASH scale, there was a statistically significant difference favorable to the patients treated with the arthroscopic technique, but without clinical relevance. There was no difference in the assessments by University of California, Los Angeles and Rowe scales. There was no statistically significant difference regarding complications and failures, as well as range of motion, for the 2 techniques. On the basis of this study, the open and arthroscopic techniques were effective in the treatment of traumatic anterior shoulder instability. The arthroscopic technique showed a lower index of functional limitation of the upper limb, as assessed by the DASH questionnaire; this, however, was not clinically relevant.

    Full Text Available The effectiveness of mechanical filtration and solar irradiation in water treatment was evaluated. Selected metals and non-metals ions before and after treatment were determined colorimetrically while turbidity was measured using a turbidimeter. pH, electrical conductivity, dissolved oxygen (DO and temperature were measured using a portable universal multiline P4 WTW meter while total alkalinity was determined titrimetrically. The load of coliform bacteria contamination before and after treatment was determined by Millipore filtration method. Screening for the presence of pathogenic bacteria was carried out using standard methods. The levels of the properties before and after treatment were each compared with the recommended drinking water standards according to Kenya Bureau of Standards (KEBS and World Health Organization (WHO. The water was treated by being subjected to mechanical filtration and solar irradiation and changes in their physico-chemical properties and bacteriological load determined. The results obtained after treatment revealed that solar irradiation killed most of the pathogenic bacteria after exposure for eight hours but had no impact on the physico-chemical properties except nitrates (from 24.5 to 8.0 mg.L-1. Mechanical filtration reduced total coliforms and E. coli by 30 %. It also reduced the loads of Zn, Cu, Mn, Pb, Fe, nitrate nitrogen and turbidity of the water treated to an almost potable state. Water treatment using a combination of mechanical filtration system and solar disinfection was found to be very effective in reducing the bacterial load.

    Purpose: The target volume for angiosarcoma of the scalp encompasses the entire scalp. Full scalp radiotherapy (FSRT) requires careful design of required bolus, immobilization and marking of the field before the patient CT is acquired. A VMAT multi-arc technique was designed to deliver FSRT for a patient with angiosarcoma of the scalp to a dose of 6000cGy in 25 fractions. Methods: A custom bolus helmet was fabricated from a 0.5 cm thick sheet of aquaplast material, which was molded to the patient’s head. With the bolus helmet in place the patient was then positioned supine on a H&N immobilization board. A custom vaclock bag positioned on a standard headrest and a thermoplastic mask were used to immobilize the patient. Additional bolus to cover the remaining treatment area was attached to the mask. We acquired two CT scans of the patient’s head, one in treatment position and an additional scan without the immobilization mask with wires marking the treatment area that the oncologist had delineated on the patient’s skin. The second scan was registered to the first and used to define the treatment CTV. A four-arc VMAT treatment planned using Varian-Eclipse was optimized to cover the skin with a PTV margin while sparing the brain and limiting the dose to the optic apparatus and lacrimal glands. Daily treatment setup was verified using anterior and lateral kV on-board-imaging. To verify the treated dose, TLDs were positioned on the patient’s scalp during one fraction. Results: With full dose coverage to the PTV, the mean dose to the brain was less than 24 Gy. The dose measured by the TLDs (mean difference 1%, standard deviation 4%)showed excellent agreement with the treatment planning calculation. Conclusion: FSRT delivered with a bolus helmet and a VMAT multi-arc technique can be accurately delivered with high dose uniformity and conformality.

    This thesis summarises and discusses results from two studies on mechanized stump treatment to control the root rot fungus Heterobasidion annosum (Fr.) Bref. In Sweden, stump treatment is at present carried out with two chemical compounds, urea and disodium octaborate tetrahydrate (DOT), and a biological control agent, Phlebiopsis gigantea (Fr.) Juel. The first study investigated the H. annosum colonization of Norway spruce (Picea abies (L.) Karst) stumps following mechanized thinning and stump treatment with the three control agents mentioned. The stumps were treated in the summer and were compared with untreated stumps, cut in the summer and winter, respectively. Experimental plots were established in 12 first thinning stands of Norway spruce. Six to seven weeks after thinning and treatment, sample discs were collected (N=1246) and examined for presence of H. annosum. Stump treatment with any of the control agents reduced the colonized stump area 6-7 weeks after thinning by 88-98% as compared with untreated stumps cut in the summer. The effects of the different treatments differed neither from each other nor from the effect of winter thinning. The variation between the stands was considerable, but mechanized stump treatment provided as good protection as manual treatment against H. annosum infections. Study II examined the survival of P. gigantea oidiospores in aqueous suspension when exposed to high temperature or pressure, which are potential problems in mechanized application. In the laboratory, temperatures of 20, 30 or 35 deg C did not affect the survival. The spores could withstand 40 deg C for a short period, but died at 60 deg C. Pressure of up to 2 200 kPa for 24 h did not affect P. gigantea spore germination. In the field, temperatures of the working suspension (10{sup 7} spores I{sup -1}) was assessed during practical operations. Spore viability was maintained through the applicator system. As long as the prescriptions are followed up to the time of

    Melanin pigmentation often occurs in the gingiva as a result of an abnormal deposition of melanin, due to which the gums may appear black, but the principles, techniques, and management of the problems associated with gingival melanin pigmentation are still not fully established. Depigmentation procedures such as scalpel surgery, gingivectomy with free gingival autografting, electrosurgery, cryosurgery, chemical agents such as 90% phenol and 95% alcohol, abrasion with diamond bur, Nd: YAG laser, semiconductor diode laser, and CO2 laser have been employed for removal of melanin hyper pigmentation. The following case series describes three different surgical depigmentation techniques: scalpel surgery, abrasion with rotary abrasive, and a diode laser. Better results of depigmentation were achieved with diode laser than conventional scalpel and with rotary abrasion with respect to esthetics. The results point out that lasers are an effective and a safe means to removal of hyperpigmentation from the gingiva. Healing was uneventful and no repigmentation occurred.

    We report a case of a 63-year-old male who experienced an iatrogenic sigmoid perforation repaired combining three endoscopic techniques. The lesion was large and irregular with three discrete perforations, therefore, we decided to close it by placing one clip per perforation, and then connecting all the clips with two endoloops. Finally we chose to use a fibrin glue injection to obtain a complete sealing. Four days after the colonoscopy the patient underwent a laparoscopic right hemicolectomy due to evidence of a large polyp of the caecum with high grade dysplasia and focal carcinoma in situ. Inspection of the sigma showed complete repair of the perforation. This report underlines how a conservative approach, together with a combination of various endoscopic techniques, can resolve complicated iatrogenic perforations of the colon.

    The use of endovascular treatment of infrapopliteal disease has increased in popularity in recent years. An improvement in technical success rates due to the availability of newer devices has fuelled an increased interest in the subject. The pathogenesis, indications for treatment, and outcome measures of infrapopliteal disease differ from larger vessel intervention. Diabetes and renal failure are prevalent. Neuropathy and venous disease contribute to the etiology of ulceration. Most interventions are undertaken for critical limb ischemia rather than claudication. Therefore, a range of conservative, pharmacological, and invasive therapies are provided. Conventional percutaneous transluminal angioplasty (PTA) using modern low-profile systems is associated with high technical success rates. However, initial data from recent randomized, controlled trials suggest that drug-eluting stents are consistently achieving improved patency over PTA alone or over bare metal stents. This review summarizes recent advances in the treatment of infrapopliteal disease.

    2014-06-01

    Patients with postthrombotic syndrome due to previous femoral-popliteal deep venous thrombosis often experience lifestyle-limiting lower-extremity pain and swelling. Conservative treatment options include compression stockings and lymphedema massage, but in many cases these treatments only temporarily and partially improve symptoms. Ultrasound and venography in patients with postthrombotic syndrome often show only partial recanalization of the femoral vein with significant collateral vein formation. These abnormal veins are insufficient for adequate venous drainage from the lower extremity as evidenced by the patient's continued symptoms. Recanalization of the occluded or partially occluded femoral vein using prolonged venoplasty, with or without chemical thrombolysis, combined with optimizing anticoagulation and conservative treatment measures, results in lasting improvement in symptoms for a high percentage of patients.

    Colovesical fistulas are a serious complication of diverticular disease. Management by one-stage resection and anastomosis has resulted in lower morbidity and shorter hospital stay. Nevertheless, hospital time remains long, approaching an average of 2-3 weeks. Here we describe our technique of laparoscopic approach to colovesical fistulas. Our initial experience suggests that this is a safe operation with minimal pain, absent ileus, and a short postoperative stay.

  12. The Principle and Technique of Using Chinese Drugs in the Treatment of Hypertension

    Institute of Scientific and Technical Information of China (English)

    周超凡; 于智敏; 李瑞泉; 田治明

    2001-01-01

    @@There are three principles which need to be grasped in the clinical use of Chinese drugs in the treatment of hypertension: Combination of syndrome differentiation in TCM with disease-differentiation in western medicine; combination of the theory of TCM with the results of modern pharmacological researches; and combination of symptom improving, blood-pressure reducing with complications preventing measures. Use of Chinese Drugs Based on the Western Medical Stages of Hypertension Patients should be classified for clinical stages of hypertension according to western medical criteria before TCM treatment program is made. For instance, in hypertension patients, apart from high blood pressure, there may also be other symptoms such as headache, dizziness, distending sensation in the head, stiff sensation in the neck, dim eyesight, tinnitus, poor memory, inability to concentrate the mind, insomnia, disphoria, general weakness, numbness of the four limbs, and palpitation. In some patients, these symptoms may not always be directly related to hypertension. In these cases, treatment for reducing blood pressure may not be taken into consideration, and the treatment based on general differentiation of the symptoms may serve the purpose. Only after the differential use of Chinese drugs shows no obvious improvement of the symptoms and high blood pressure, the treatment will be aimed at hypertension per se. When Chinese drugs alone can not reduce blood pressure, western medicine is often used in combination to reduce blood pressure, blood lipids and uric acid, correct water-electrolyte metabolism, and improve blood rheology. The combined Chinese and western medical treatment can make up each other's deficiencies so as to give better therapeutic effects.

    In the treatment of prostatic cancer using a newly proposed intermittent multiportal therapy (DIMT), acute reactions, change in tumor marker levels, and complications more than 6 months after treatment were evaluated. From June 1989 to September 1990, 26 patients with prostatic cancer (stage A2, 3 patients; B, 9; C, 2; D, 10; recurrence, 2) were treated. Fifteen patients were followed up for more than one year, with a mean period of 11.6 months. The treatment schedule is 52.5 Gy in 16 fractions in 4 weeks for radical treatment, and 30.0 Gy in 8 fractions in 2 weeks for palliative treatment. The 360 degree rotation about the patient was divided into 16 fractions, and 2 opposing fractions were used in one day as parallel opposed portals to treat the target volume. The fractions were serially treated one per day, so that 8 treatment days produced a total dose of distribution similar to that for conventional conformational therapy. The size of the irradiation field varied from 6 x 6 cm to 9 x 9 cm. No hormonal therapy was performed for stage A2 or B. Acute effect was minimal including skin erythema 2/26 (7%), pollakisuria 1/26 (4%), mild symptoms due to acute proctitis 9/26 (35%). Abnormality high PSA and/or PAP levels returned to the normal range after the treatment in 7 of 10 patients. Local recurrence was detected in 1 patient with stage D, 15 months after completion of therapy, but 21 other patients continued for more than 6 months with no clinical evidence of local recurrence. No residual disease was detected by biopsy undertaken in 10 patients after more than 6 months. No severe complication was detected after more than 6 months except in 1 patient who needed colostomy for the relief of rectal bleeding. DIMT can have the total dose distribution similar to that of conventional conformational therapy without specific devices. Initial results on prostatic cancer treatment were encouraging. (J.P.N.).

    Increasing demand for limited fresh water resources necessitates that alternative water sources be developed. Nonpotable reuse of treated wastewater represents one such alternative. However, the ubiquitous presence of organic micropollutants such as pharmaceuticals and personal care products (PPCPs) in wastewater effluents limits use of this resource. Numerous investigations have examined PPCP fate during wastewater treatment, focusing on their removal during conventional and advanced treatment processes. Analysis of influent and effluent data from published studies reveals that at best 1-log10 concentration unit of PPCP removal can generally be achieved with conventional treatment. In contrast, plants employing advanced treatment methods, particularly ozonation and/or membranes, remove most PPCPs often to levels below analytical detection limits. However, membrane treatment is cost prohibitive for many facilities, and ozone treatment can be very selective. Ozone-recalcitrant compounds require the use of Advanced Oxidation Processes (AOPs), which utilize highly reactive hydroxyl radicals (*OH) to target resistant pollutants. Due to cost and energy use concerns associated with current AOPs, alternatives such as catalytic ozonation are under investigation. Catalytic ozonation uses substrates such as activated carbon to promote *OH formation during ozonation. Here, we show that multi-walled carbon nanotubes (MWCNTs) represent another viable substrate, promoting *OH formation during ozonation to levels exceeding activated carbon and equivalent to conventional ozone-based AOPs. Via a series of batch reactions, we observ a strong correlation between *OH formation and MWCNT surface oxygen concentrations. Results suggest that deprotonated carboxyl groups on the CNT surface are integral to their reactivity toward ozone and corresponding *OH formation. From a practical standpoint, we show that industrial grade MWCNTs exhibit similar *OH production as their research

    The success achieved with large-scale plants for mechanical-biological residual waste treatment has led to a change of course in waste pretreatment. In view of the low emissions via the water and gas routes from landfilled wastes and the low costs of waste treatment some authorising authorities have meanwhile issued special licences pursuant to clause no. 2.4 of the Technical Code on Household Waste, thus enabling mechanical-biological residual waste treatment plants to continue operations beyond the year 2005. Beside offering a means of treatment and disposal, cost-effective mechanical-biological pretreatment also provides an opportunity for going over to material-flow-specific residual waste treatment. These process stages permit recirculating valuable materials and using other materials for energy production. They can be retrofitted on a modular basis in existing plants. If these advantages of the present innovative pretreatment methods are not used, then mechanical-biological pretreatment can still serve as a preparatory stage for thermal treatment. To date there has been no practical experience with this innovative method of residual waste treatment. However, industrial-scale trials have shown that each individual treatment stage is capable of being carried out successfully.

    With few exceptions, research in the addictive sciences has relied on linear statistics and methodologies. Addiction involves a complex array of nonlinear behaviors. This study applies two machine learning techniques, Bayesian and decision tree classifiers, in the assessment of outcome of an alcohol dependence treatment program. These nonlinear approaches are compared to a standard linear analysis. Seventy-three alcohol-dependent subjects undertaking a 12-week cognitive-behavioral therapy (CBT) program and 66 subjects undertaking an identical program but also prescribed the relapse prevention agent Acamprosate were employed in this study. Demographic, alcohol use, dependence severity, craving, health-related quality of life, and psychological measures at baseline were used to predict abstinence at 12 weeks. Decision trees had a 77% predictive accuracy across both data sets, Bayesian networks 73%, and discriminant analysis 42%. Combined with clinical experience, machine learning approaches offer promise in understanding the complex relationships that underlie treatment outcome for abstinence-based alcohol treatment programs.

    Proton radiation therapy is an effective modality for cancer treatments, but the cost of proton therapy is much higher compared to conventional radiotherapy and this presents a formidable barrier to most clinical practices that wish to offer proton therapy. Little attention in literature has been paid to the costs associated with collimators, range compensators and hypofractionation. The objective of this study was to evaluate the feasibility of cost-saving modifications to the present standard of care for proton treatments for prostate cancer. In particular, we quantified the dosimetric impact of a treatment technique in which custom fabricated collimators were replaced with a multileaf collimator (MLC) and the custom range compensators (RC) were eliminated. The dosimetric impacts of these modifications were assessed for 10 patients with a commercial treatment planning system (TPS) and confirmed with corresponding Monte Carlo simulations. We assessed the impact on lifetime risks of radiogenic second cancers using detailed dose reconstructions and predictive dose-risk models based on epidemiologic data. We also performed illustrative calculations, using an isoeffect model, to examine the potential for hypofractionation. Specifically, we bracketed plausible intervals of proton fraction size and total treatment dose that were equivalent to a conventional photon treatment of 79.2 Gy in 44 fractions. Our results revealed that eliminating the RC and using an MLC had negligible effect on predicted dose distributions and second cancer risks. Even modest hypofractionation strategies can yield substantial cost savings. Together, our results suggest that it is feasible to modify the standard of care to increase treatment efficiency, reduce treatment costs to patients and insurers, while preserving high treatment quality.

One method that has the potential to elicit individual core beliefs is the "repertory grid technique." This study utilized the repertory grid technique to elicit individuals' beliefs about their heart failure treatment and to investigate whether generated constructs were different between adherent and nonadherent patients.Methods: Ninety-two patients with heart failure were interviewed using a structured questionnaire that applied the repertory grid technique. Patients were asked to compare and contrast their medicines and self-care activities for their heart failure. This lead to the generation of individual constructs (perceptions towards medicines, and from these, beliefs were elicited about their heart failure treatment, resulting in the generation of a repertory grid. Adherence was measured using the Medication Adherence Report Scale (MARS. Patients with a MARS score ≥ 23 were categorized as "adherent" and those with a score ≤ 22 as "nonadherent." The generated grids were analyzed descriptively and constructs from all grids themed and the frequency of these constructs compared between adherent and nonadherent patients.Results: Individual grids provided insight into the different beliefs that patients held about their heart failure treatment. The themed constructs "related to water," "affect the heart," "related to weight," and "benefit to the heart" occurred more frequently in adherent

    This paper provides an overview of alternatives to conventional thermal treatments and a review of the literature on fruit-juice processing for three key operations in fruit-juice production such as microbial inactivation, enzyme inactivation, and juice yield enhancement, these being radiation treatments (UV light, high-intensity light pulses, γ-irradiation), electrical treatments (pulsed electric fields, radiofrequency electric fields, ohmic heating), microwave heating, ultrasound, high hydrostatic pressure, inert gas treatments (supercritical carbon dioxide, ozonation), and flash-vacuum expansion. The nonthermal technologies discussed in this review have the potential to meet industry and consumer expectations. However, the lack of standardization in operating conditions hampers comparisons among different studies, and consequently ambiguity arises within the literature. For the juice industry to advance, more detailed studies are needed on the scaling-up, process design, and optimization, as well as on the effect of such technologies on juice quality of juices in order to maximize their potential as alternative nonthermal technologies in fruit-juice processing.

    We report the use of longitudinal (aspect ratio > 1 : 1) scanning atomic force microscopy as an aid in returning to the same area of hair fibres after bleaching, treatment with a commercial shampoo or the application of a 'leave-on' conditioner product. The bleaching treatment used in this study was not found to affect the cuticular architecture and lateral force microscopy (LFM) also showed little difference after treatment, reflecting the homogeneity of the newly revealed surfaces. After treatment with a commercial shampoo, the hair sample again showed very little difference in topography or lateral force characteristics. Hair treated with the leave-on conditioner product also showed no major topographical changes. LFM traces, however, showed regions between the ghost edge, marking the original position of the scale edge before cuticular erosion, and the existing scale edge, to have higher frictional properties than distal regions of the cuticle. A thin film of the leave-on product thus seems to form in this region and extends from the foot of the scale edge.

    1997-01-01

    This R and D program addresses the treatment of mixed waste employing the ChemChar Thermolytic Detoxification process. Surrogate mixed waste streams will be treated in a four inch diameter, continuous feed, adiabatic reactor with the goal of meeting all regulatory treatment levels for the contaminants in the surrogates with the concomitant production of contaminant free by-products. Successful completion of this program will show that organic contaminants in mixed waste surrogates will be converted to a clean, energy rich synthesis gas capable of being used, without further processing, for power or heat generation. The inorganic components in the surrogates will be found to be adsorbed on a macroporous coal char activated carbon substrate which is mixed with the waste prior to treatment. These contaminants include radioactive metal surrogate species, RCRA hazardous metals and any acid gases formed during the treatment process. The program has three main tasks that will be performed to meet the above objectives. The first task is the design and construction of the four inch reactor at Mirage Systems in Sunnyvale, CA. The second task is production and procurement of the activated carbon char employed in the ChemChartest runs and identification of two surrogate mixed wastes. The last task is testing and operation of the reactor on char/surrogate waste mixtures to be performed at the University of Missouri. The deliverables for the project are a Design Review Report, Operational Test Plan, Topical Report and Final Report. This report contains only the results of the design and construction carbon production-surrogate waste identification tasks.Treatment of the surrogate mixed wastes has just begun and will not be reported in this version of the Final Report. The latter will be reported in the final version of the Final Report.

    Full Text Available This study was carried out with the cooperation of farmers owning communally grazed indigenous goats in southwestern KwaZulu-Natal Province, South Africa, where farmers had identified poor reproductive performance in their herds as one of their major problems. The aim was to quantify the effects of 3 interventions and the interaction between these interventions on goat productivity and gastrointestinal nematode infection. The interventions were: urea-molasses block supplementation during the dry winter seasons of 2004 and 2005, tactical anthelmintic treatment with ivermectin (400 µg/kg during the wet summer period (on 3 January 2005 and symptomatic treatment with ivermectin (400 mg/kg of all goats judged anaemic throughout the entire study period. The FAMACHA© system was used as a gauge of anaemia. It was noted that goats considered anaemic tended to remain so throughout the study period. The tactical anthelmintic treatment was effective as it markedly reduced (P=0.066 the summer peak in faecal egg counts and is therefore recommended. By contrast, while the urea-molasses block supplementation appeared to reduce the faecal egg counts immediately following the 2004 supplementation (P < 0.05, this did not hold true in 2005. Interestingly, in the tactically treated anaemic goats, the improvement in the number of kids suckled per doe year-on-year tended to be greater than in the non-anaemic goats. It is considered that the routine symptomatic treatment of anaemic goats may have been a key factor. More detailed investigations into the routine symptomatic treatment of anaemic goats are therefore recommended.

    In this work, techniques for monitoring the intramolecular transglutaminase cross-links of pea proteins, based on protein size determination, were developed. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis profiles of transglutaminase-treated low concentration (0.01% w/w) pea albumin samples, compared to the untreated one (control), showed a higher electrophoretic migration of the major albumin fraction band (26 kDa), reflecting a decrease in protein size. This protein size decrease was confirmed, after DEAE column purification, by dynamic light scattering (DLS) where the hydrodynamic radius of treated samples appears to be reduced compared to the control one.

  12. Thermoplastic vestibuloplasty: a novel technique for treatment of lip and cheek adhesion.

    Barakat, Khaled; Ali, Aya

    2014-12-01

    Lip and cheek adhesion to the opposing alveolus with complete or partial loss of the vestibular dimension represents a challenging problem for reconstruction. It usually occurs due to primary inadequate vestibular soft tissue repair following complicated trauma cases, burns, and lesions of the oral cavity. Surgical removal of scar tissue and creation of new vestibule is complicated by readhesion between the opposing connective tissue surfaces. Skin grafts and acellular dermal matrix represent the most dominant modalities used to treat deficient vestibule dimensions, but they are difficult to fix and lack the required stability during healing. Several devices have been created in an attempt to keep the tissues apart but their complex anchorage methods seriously reduced their reliability and usage. We devised a simple and reliable technique "thermoplastic vestibuloplasty" (TV) that benefit from the inherent reepithelialization capabilities of the oral mucosa to prevent readhesion and to resurface the created vestibule with its exact tissue color and texture. In total, 10 patients suffering from complete or partial lip or cheek adhesion with concomitant loss of vestibule were surgically treated by excising scar tissue and creating a new vestibule, followed by TV technique. Pre and posttreatment results were compared in terms of vestibular length, lip or cheek mobility, and change by time in vestibular length from 2 weeks up to 3 months. Moreover, the patient satisfaction and outcomes were measured using visual analogue scale score. All patients tolerated the procedure without complication. The mean vestibule length and mobility significantly increased from 3.8 + 0.6 mm to 11.4 + 1.4 mm (p < 0.001) and from 0.3 to 2 (p < 0.001), respectively. Regarding the stability of the achieved vestibular length it decreased by 14% when compared from 2 weeks to 3 months postoperatively. TV technique is a new simple and reliable technique that can effectively

    The method of treating anal fistula with YAG laser technique is described in this essay. One-hundred-twenty patients have been treated successfully with this method and no recurrence was found in our series. Anal fistula is a common disorder in the anus and rectum. The tunnel of fistula zigzags around the external or internal sphincters. If the drainage is poor, and the skin around the external opening grows rapidly, false healing may occur and cause recurrent abscess. In this case, a fistula can not be cured except by operation.

    Full Text Available Abstract Background Trigger points have been shown to be active in many myofascial pain syndromes. Treatment of trigger point pain and dysfunction may be explained through the mechanisms of central and peripheral paradigms. This study aimed to investigate whether the mind/body treatment of Neuro Emotional Technique (NET could significantly relieve pain sensitivity of trigger points presenting in a cohort of chronic neck pain sufferers. Methods Sixty participants presenting to a private chiropractic clinic with chronic cervical pain as their primary complaint were sequentially allocated into treatment and control groups. Participants in the treatment group received a short course of Neuro Emotional Technique that consists of muscle testing, general semantics and Traditional Chinese Medicine. The control group received a sham NET protocol. Outcome measurements included pain assessment utilizing a visual analog scale and a pressure gauge algometer. Pain sensitivity was measured at four trigger point locations: suboccipital region (S; levator scapulae region (LS; sternocleidomastoid region (SCM and temporomandibular region (TMJ. For each outcome measurement and each trigger point, we calculated the change in measurement between pre- and post- treatment. We then examined the relationships between these measurement changes and six independent variables (i.e. treatment group and the above five additional participant variables using forward stepwise General Linear Model. Results The visual analog scale (0 to 10 had an improvement of 7.6 at S, 7.2 at LS, 7.5 at SCM and 7.1 at the TMJ in the treatment group compared with no improvement of at S, and an improvement of 0.04 at LS, 0.1 at SCM and 0.1 at the TMJ point in the control group, (P Conclusion After a short course of NET treatment, measurements of visual analog scale and pressure algometer recordings of four trigger point locations in a cohort of chronic neck pain sufferers were significantly

    Aging is associated with morphological and functional changes in the brain, resulting in the deterioration of cognitive performance. Growth factors like BDNF are suggested to be involved in the regulation of age-related processes in the brain. A novel dietary supplement produced from purified nerve cell proteins, N-PEP-12, has shown to share properties with naturally occurring peptide growth factors by stimulating neurite outgrowth and beneficial effects on neuronal survival and protection against metabolic stress in cell cultures. The current study investigates the effects of long-term intake on age-dependent memory decline by assessing cognitive performance and synaptic density. All the experiments were performed in aged Long Evans rats randomly assigned to saline or N-PEP-12 once daily by gavage over a period of three months. Behavioral tests were performed in the Morris Water Maze after one, two and three months of treatment. Histological examinations were performed in the hippocampal formation and in the entorhinal cortex by measuring the synaptic density. This study shows that the oral intake of N-PEP-12 has beneficial effects on the cognitive performance of aged animals and that these effects go along with an increase in the synaptic density. Thus, N-PEP-12 may help maintain memory and learning performance during the aging process.

    Full Text Available Today bacterial abscesses remain one of the most difficult complications in surgical hepatology, both traditional and minimally invasive methods of their treatment are used. Bio-statistical analysis is used due to the fact that strong evidences are required for the effectiveness of one or another method of surgical intervention. The estimation of statistical significance of differences between the control and the main group of patients with liver abscesses is given in this paper. Depending on the treatment method patients were divided into two groups: 1 - minimally invasive surgery (89 cases; 2 – laporatomy surgery (74 patients. Data compa¬ri¬son was performed by means of Stjudent's criterion. The effectiveness of method of abscesses drainage using inter¬ventional sonography, outer nazobiliar drainage with reorganization of ductal liver system and abscess cavity with the help of modern antiseptics was considered. The percentage of cured patients was also estimated.

    Radiation therapy (RT) is an essential component of the management of many cancers. Traditionally, a course of external bream RT often involved daily treatments for a duration of 6 weeks or longer in some instances. Now, however, emerging clinical evidence indicates that, for some common cancers, the total length of treatment can be substantially shortened, offering convenience to patients and opportunities for resource utilization efficiencies. This trend toward so-called hypofractionated RT has been supported by hypothesis-driven clinical research guided by a combination of radiobiological and clinical insights and technological enhancements. The present review presents the rationale behind and current status of hypofractionation for prostate, breast, and medically inoperable early stage lung cancer.

    2015-01-01

    In recent years, the use of PACS for radiation therapy has become the norm in hospital environment and has suggested for collecting data and management from different TPSs with DICOM objects. However, some TPS does not provide the DVH exportation with text or other format. In addition, plan review systems for various TPSs often allow DVH recalculation with different algorithms. These algorithms result in the inevitable discrepancy between the values obtained with the recalculation and those obtained with TPS itself. The purpose of this study was to develop a simple method for generating reproducible DVH values obtained from the TPSs. Treatment planning information including structures and delivered dose was exported by the DICOM format from planning systems. The supersampling and trilinear interpolation methods were employed to calculate DVH data from 35 treatment plans. The discrepancies between DVHs extracted from each TPS and the proposed calculation method were evaluated with respect to the supersampling ...

    Full Text Available The aim of this study was to evaluate the effectiveness of a new technical variant applied to the Gufoni's manoeuvre, in the treatment of horizontal canal benign paroxysmal positional vertigo (HSC-BPPV. 87 patients with BPPV of HSC (55 women and 32 men, aged between 21 and 80 years, were randomized either to modified Gufoni's manoeuvre or to the Gufoni's manoeuvre. 93% of patients treated with modified Gufoni's manoeuvre was cured after the first treatment session, of which only 2% had a conversion into PSC-BPPV, while the Gufoni's manoeuvre led to a symptoms resolution in 88% of cases, of which 16% had a conversion into PSC-BPPV. Therefore, the modified Gufoni's manoeuvre shows the same effectiveness in the resolution of symptoms of Gufoni's manoeuvre, but it appears more effective than the latter to reduce the percentage of conversion of the HSC-BPPV into PSC-BPPV (χ2=6.13, P=0.047.

    Full Text Available Objectives. This study analyzed the long-term hearing loss after treatment of primary nasopharyngeal carcinoma to elucidate its causal factors. Methods. Ninety-two nasopharyngeal carcinoma patients were treated with radiotherapy or chemoradiotherapy. Pure tone audiometry was performed before the therapy and annually up to 9 years after completing treatment. The hearing thresholds were corrected for age-related deterioration and compared to the results without adjusting for age. Results. The mean air and bone conduction threshold with and without correction for age-related deterioration differed significantly 2–9 years after completing radiotherapy p72 cGy resulted in more severe hearing loss than <72 cGy p<0.05. Conclusion. Hearing loss after completing therapy should be corrected for age-related hearing deterioration to reveal the true extent to which the loss is a therapeutic complication. Both the radiation modality used and the dose were significantly associated with hearing loss.

    Family systems theory views anorexia nervosa not only as a product of dysfunctional transactional patterns within a family, but also as a crucial stabilizing element within the family. This paper describes the dysfunctional characteristics of anorexic families as well as the relevance of these characteristics to the anorexic symptoms. Two approaches to the treatment of these families, one developed by Minuchin and the other by Selvini Palazzoli, are described and the compatability of family therapy with individual therapy is briefly discussed.

    The structure of bio-carriers is one of the key operational characteristics of a biofilm reactor. The goal of this study is to develop a series of novel fullerene-type bio-carriers using the three-dimensional printing (3DP) technique. 3DP can fabricate bio-carriers with more specialized structures compared with traditional fabrication processes. In this research, three types of fullerene-type bio-carriers were fabricated using the 3DP technique and then compared with bio-carrier K3 (from AnoxKaldnes) in the areas of physicochemical properties and biofilm growth. Images acquired by 3D profiling and SEM indicated that the surface roughness of the 3DP bio-carrier was greater than that of K3. Furthermore, contact angle data indicated that the 3DP bio-carriers were more hydrophilic than K3. The biofilm on the 3DP bio-carriers exhibited higher microbial activity and stronger adhesion ability. These findings were attributed to excellent mass transfer of the substrate (and oxygen) between the vapour-liquid-solid tri-phase system and to the surface characteristics. It is concluded that the novel 3DP fullerene-type bio-carriers are ideal carriers for biofilm adherence and growth. PMID:26202477

    This study compares static conformal field (CF), intensity modulated radiotherapy (IMRT), and dynamic arcs (DA) for the stereotactic radiotherapy of base-of-skull meningiomas. Twenty-one cases of base-of-skull meningioma (median planning target volume [PTV] = 21.3 cm3) previously treated with stereotactic radiotherapy were replanned with each technique. The plans were compared for Radiation Therapy Oncology Group conformity index (CI) and homogeneity index (HI), and doses to normal structures at 6 dose values from 50.4 Gy to 5.6 Gy. The mean CI was 1.75 (CF), 1.75 (DA), and 1.66 (IMRT) (p size of the PTV (Spearman's rho = -0.53, p = 0.01) and at PTV sizes above 25 cm3, the CI (IMRT) was always superior to CI (DA) and CI (CF). At PTV sizes below 25 cm3, there was no significant difference in CI between each technique. There was no significant difference in HI between plans. The total volume of normal tissue receiving 50.4, 44.8, and 5.6 Gy was significantly lower when comparing IMRT to CF and DA plans (p conformity and normal tissue sparing, in particular for the brain stem and ipsilateral temporal lobe.

    There are many variables that influence nose tip harmony. Even in a rhinoplasty that appears successful in profile, one may see nostril asymmetries, alar retractions, or irregularities in the soft triangle, and patients express their dissatisfaction with these simple deformities. In this study, we define the ratio of caudal and cephalic excess of the lower lateral cartilage. We evaluate whether it is possible to eliminate nostril asymmetries and alar retractions by means of supporting the facet polygon with the help of a lower lateral cartilage auto-rim flap, a technique we have developed in our rhinoplasties. The auto-rim flap was used successively on 498 primary rhinoplasty patients on whom the same surgeon operated between May 2013 and June 2015, performing marginal incisions. Of the 498 patients in the series, only 1 of the first 10 required a revision due to tip asymmetry related to the auto-rim flap. A minimal nostril asymmetry that did not require intervention occurred in 10 patients. In none of the patients could an increased alar retraction be seen postoperatively. All patients exhibited alar cartilage in the anatomically correct position. With the auto-rim flap technique, a part of the caudal excess of the alar cartilage remains as a flap in the facet region; therefore, there is no need in the cephalic region to perform more of an excision than what is strictly necessary. 4 Therapeutic. © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

    Plantar warts are common and often painful. Treatment of plantar warts is difficult and requires multiple treatments. Several clinical trials have proven the efficacy of bleomycin, but relatively high concentrations have been required and considerable side effects have been experienced. To evaluate the efficacy and safety of low-concentration (0.1 U/mL) bleomycin using a translesional injection technique for the treatment of plantar warts. The study included 23 patients with single or multiple plantar warts. Very low-concentration bleomycin was injected into a single wart or the largest plantar wart in the case of multiple lesions. Injections were performed at 4-week intervals until resolution of the warts or development of side effects. The translesional multipuncture technique was used. Thirteen patients were male (56.5%), and the mean age was 27.7 years. The results revealed complete clearance of warts in 17 of 23 (74%) patients, partial response in 1 (4.3%) patient, and no response in 3 (13%) patients. Recurrence was observed in 2 patients at 3 months of follow-up. Among those two, one patient showed complete clearance after the second injection at 6 months of follow-up. All patients were followed for 6 months after the initial treatment. No significant long-term adverse effects were noted. Only three patients (13%) had localized moderate pain for 2 to 3 days after the injection. Translesional injection by very low-concentration (0.1 U/mL) bleomycin appears to be a simple, effective, and safe treatment modality for plantar warts.

    The purpose of this single-institution study was to describe our 7-year intention-to-treat results, obtained with the use of endovascular techniques for the treatment of ruptured abdominal aortic aneurysms (rAAA). From October 1998 until March 2005, a total of 28 patients were admitted or transferred to our department with an rAAA. They were all treated according to a management protocol of intention-to-treat with endovascular techniques. Twenty of the patients received endovascular treatment and the remaining 8 underwent an open surgery procedure. The mortality rate of the endovascularly treated patients was 40% (8 in 20), whereas of the 8 surgical patients 3 survived (mortality = 62.5%). The overall mortality rate of the 28 patients admitted with an rAAA was 46.4% (13 of 28 patients). In our experience the intension-to-treat protocol for rAAA offered acceptable results in terms of mortality rates. Multi-center studies are necessary to establish the role of endovascular treatment in patients with rAAA.

    Verification of radiotherapy treatments in head and neck requires, among other things, small volume chambers and a phantom to reproduce the geometry and density of the anatomical structure. New documents from the ICRU (International Commission on Radiation Units and Measurements), Report 83, established the need for quality control in radiotherapy with special techniques such as IMRT (intensity-modulated radiation therapy). In this study, we built a cylindrical acrylic phantom with standing water, containing seven measuring points in the transverse plane and free location (0-20 cm) in the longitudinal plane. These points of measurement are constituted by cavities for the accommodation of the ionization chamber of 7 mm of mayor diameter (semi flex, pinpoint with build cup). The results of the phantom validation yielded percentage differences less than 1% in fixed beams and less than 2.5% in arc therapy for TPS Eclipse calculation. The preparation of this phantom, particularly made to verify the head and neck treatments, was simple and reliable for checking the dose in radiotherapy with fixed beams and/or special techniques such as arc therapy or IMRT, so that will be sent to various radiotherapy centers in the country for dosimetric verification in such treatments.

    In order to investigate microbial community structures in different wastewater treatment processes and understand the relationship between the structures and the status of processes, the microbial community diversity, variety and distribution in five wastewater treatment processes were studied by a culture-independent genetic fingerprinting technique single-strand conformation poly-morphism (SSCP). The five processes included denitrifying and phosphate-removal system (diminished N), Chinese traditional medicine wastewater treatment system (P), beer wastewater treatment system (W), fermentative biohydrogen-producing system (H), and sulfate-reduction system (S). The results indicated that the microbial community profiles in the wastewater bioreactors with the uniform status were very similar. The diversity of microbial populations was correlated with the complexity of organic contaminants in wastewater. Chinese traditional medicine wastewater contained more complex organic components; hence, the population diversity was higher than that of simple nutrient bioreactors fed with molasses wastewater. Compared with the strain bands in a simulated community, the relative proportion of some functional microbial populations in bioreactors was not dom-inant. Fermentative biohydrogen producer Ethanoligenens harbinense in the better condition bioreactor had only a 5% band density, and the Desulfovibrio sp. in the sulfate-reducing bioreactor had less than 1.5% band density. The SSCP profiles could identify the difference in microbial community structures in wastewater treatment processes, monitor some of the functional microbes in these processes, and consequently provide useful guidance for improving their efficiency.

    Twenty-five displaced intra-articular calcaneal fractures in 21 patients, aged 15-55 years were included in this study. Sanders' type I fractures, severe crushing or partial amputation, were excluded from the study. Patients were divided into group 1 (open fractures treated by MIS), and group 2 (closed fractures treated by ORIF). Group 1 had 16 and group 2 had 9 cases. Seven of 25 fractures (28%) developed wound related issues postoperatively. One patient (11.1%) in group 2 had wound margin necrosis, while 6 patients (37.5%) in group 1 developed pin tract and/or wound infection. At 1-year follow-up, the mean MFS for group 1 was 79 and mean MFS for group 2 was 84.4 (66.67% were good). The AOFAS score for group 1 was 77.37 and for group 2 was 86.1. The Bohlers' angle was restored in 81.16% cases in group 1 and 88.8% in group 2, while Gissane angle was restored in 68.75% of group 1 cases and 77.79% of group 2 cases. This study shows that acceptable fracture reduction can be obtained and maintained by MIS technique and it can be used as the primary definitive treatment option in open calcaneal fractures.

    2009-05-01

    Full Text Available "nCarious primary teeth are still a great problem in many countries. Maintaining these teeth, which play a significant role in chewing, guiding the permanent teeth to erupt normally and keeping the ideal dental arch size, is very important. The most common treatment of the deep carious primary teeth is pulpotomy. Many techniques and sub-base materials have been suggested for this purpose. "nAll traditional sub-base materials have been found to have different percentages of failure. Bonding systems are widely used in dentistry for tooth restoration. Their greatest advantage is providing better seal in the tooth-restoration interface, which is the primary goal in restorative dentistry.  The authors' suggestion is to use these materials as a sub-base agent subsequent to the electrosurgical pulpotomy technique. Bonding systems are easy to use, time efficient, biocompatible, do not need sealing pressure, and additionally provide an ideal seal.

    He, Yunxia; Xu, Zhenming

    2014-04-01

    A large quantity of waste electrical and electronic equipment (WEEE) is being generated because technical innovation promotes the unceasing renewal of products. China's household appliances and electronic products have entered the peak of obsolescence. Due to lack of technology and equipment, recycling of WEEE is causing serious environment pollution. In order to achieve the harmless disposal and resource utilization of WEEE, researchers have performed large quantities of work, and some demonstration projects have been built recently. In this paper, the treatment techniques of typical WEEE components, including printed circuit boards, refrigerator cabinets, toner cartridges, cathode ray tubes, liquid crystal display panels, batteries (Ni-Cd and Li-ion), hard disk drives, and wires are reviewed. An integrated recycling system with environmentally friendly and highly efficient techniques for processing WEEE is proposed. The orientation of further development for WEEE recycling is also proposed.

    Vailati, Francesca; Carciofo, Sylvain

    2016-01-01

    A full-mouth rehabilitation should be correctly planned from the start by using a diagnostic wax-up to reduce the potential for remakes, increased chair time, and laboratory costs. However, determining the clinical validity of an extensive wax-up can be complicated for clinicians who lack the experience of full-mouth rehabilitations. The three-step technique is a simplified approach that has been developed to facilitate the clinician's task. By following this technique, the diagnostic wax-up is progressively developed to the final outcome through the interaction between patient, clinician, and laboratory technician. This article provides guidelines aimed at helping clinicians and laboratory technicians to become more proactive in the treatment planning of full-mouth rehabilitations, by starting from the three major parameters of incisal edge position, occlusal plane position, and the vertical dimension of occlusion.

    2015-01-01

    Introduction A preliminary study done by a National Dental Practice-Based Research Network precursor observed that 44% of general dentists (GDs) reported always using a rubber dam (RD) during root canal treatment (RCT). This full-scale study quantified use of all isolation techniques, including RD use. Methods Network practitioners completed a questionnaire about isolation techniques used during RCT. Network Enrollment Questionnaire data provided practitioner characteristics. Results 1,490 of 1,716 eligible GDs participated (87%); 697 (47%) reported always using a RD. This percentage varied by tooth type. These GDs were more likely to always use a RD: do not own a private practice; perform less than 10 RCT/month; have postgraduate training. Conclusions Most GDs do not use a RD all the time. Ironically, RDs are used more frequently by GDs who do not perform molar RCT. RD use varies with tooth type and certain dentist, practice, and patient characteristics. PMID:26015159
