After reading this article, the participant should be able to: 1. Describe the concept of early protected movement with Kirschner-wired finger fractures to the hand therapist. 2. Choose the most appropriate method of fracture fixation to achieve the goal of a full range of motion. 3. Describe the methods of treatment available for the most common fractures and dislocations of the hand. The main goal of treatment of hand and finger fractures and dislocations is to attain a full range of wrist and nonscissoring finger motion after the treatment is accomplished. This CME article consists of literature review, illustrations, movies, and an online CME examination to bring the participant recent available information on the topic. The authors reviewed literature regarding the most current treatment strategies for common hand and finger fractures and dislocations. Films were created to illustrate operative and rehabilitation methods used to treat these problems. A series of multiple-choice questions, answers, discussions, and references were written and are provided online so that the participant can receive the full benefit of this review. Many treatment options are available, from buddy and Coban taping to closed reduction with immobilization; percutaneous pins or screws; and open reduction with pins, screws, or plates. Knowledge of all available options is important because all can be used to achieve the goal of treatment in the shortest time possible. The commonly used methods of treatment are reviewed and illustrated. Management of common hand and finger fractures and dislocations includes the need to focus on achieving a full range of motion after treatment. A balance of fracture reduction with minimal dissection and early protected movement will achieve the goal.

Emergency Stabilization and Rehabilitation (ES&R) and Burned Area Emergency Response (BAER) treatments are short-term, high-intensity treatments designed to mitigate the adverse effects of wildfire on public lands. The federal government expends significant resources implementing ES&R and BAER treatments after wildfires; however, recent reviews have found that existing data from monitoring and research are insufficient to evaluate the effects of these activities. The purpose of this report is to: (1) document what monitoring methods are generally used by personnel in the field; (2) describe approaches and methods for post-fire vegetation and soil monitoring documented in agency manuals; (3) determine the common elements of monitoring programs recommended in these manuals; and (4) describe a common monitoring approach to determine the effectiveness of future ES&R and BAER treatments in non-forested regions. Both qualitative and quantitative methods to measure effectiveness of ES&R treatments are used by federal land management agencies. Quantitative methods are used in the field depending on factors such as funding, personnel, and time constraints. There are seven vegetation monitoring manuals produced by the federal government that address monitoring methods for (primarily) vegetation and soil attributes. These methods vary in their objectivity and repeatability. The most repeatable methods are point-intercept, quadrat-based density measurements, gap intercepts, and direct measurement of soil erosion. Additionally, these manuals recommend approaches for designing monitoring programs for the state of ecosystems or the effect of management actions. The elements of a defensible monitoring program applicable to ES&R and BAER projects that most of these manuals have in common are objectives, stratification, control areas, random sampling, data quality, and statistical analysis. The effectiveness of treatments can be determined more accurately if data are gathered using an approach that incorporates these six monitoring program design elements and objectives, as well as repeatable procedures to measure cover, density, gap intercept, and soil erosion within each ecoregion and plant community. Additionally, using a common monitoring program design with comparable methods, consistently documenting results, and creating and maintaining a central database for query and reporting, will ultimately allow a determination of the effectiveness of post-fire rehabilitation activities region-wide.

2017-07-01
This study was conducted to determine the pediatric usage of complementary/alternative medicine (CAM) by parents in Turkey, the incidence of using these methods, and the factors affecting their use. The sectional and relational design of the study included a sample of 497 parents who took children for treatment at the Maternity and Children's Hospital in Giresun, Turkey. Data for the study were collected via the Personal Information Form and the Evaluation Form for Complementary/Alternative Treatment Use. The data collection tools were filled out by the researchers during the face-to-face interviews. Data obtained from the study were analyzed by Pearson chi-square, Fisher-Freeman-Halton and Fisher's exact (posthoc Bonferroni) tests and Z-test. It was determined that 97.7% of the parents had used at least one CAM method. Moreover, the parents had used CAM methods mostly for respiratory complaints. The CAM methods were most commonly used for the symptoms of fever, diarrhea, and cough. It was observed that the most commonly used alternative methods in the past were vitamin/mineral remedies, cold treatments, and hodja (Islamic teacher) consultations, while the most common alternative methods currently used are massage, music, and cold treatment. In addition, the differences found between CAM users in terms of sociodemographic characteristics were not statistically significant. It is crucial for nurses to learn the characteristics of the health/disease treatments used by those with whom they work in order to increase the efficiency of the service they provide. Thus, it was recommended that nurses should be knowledgeable and aware of the benefits/side effects, treatment methods, and contraindications of CAM. © 2017 Wiley Periodicals, Inc.

Plants have been the primary source of medicines since life on earth; more than 50 % of existing cancer treatments are derived from plants. An ethnopharmacological survey of herbal remedies used in cancer treatment was carried out in the West Bank/ Palestine. A questionnaire was distributed to one hundred and fifty herbalists, traditional healers and rural dwellers. Collected information included the names of plants, the used parts, types of cancers for which these plants were used and also their methods of preparation. To identify the most important species used, Factor of informant's consensus (F(ic)), Fidelity level (Fl) and the Use-value (UV) were calculated. Collected data has shown that 72 plants are utilized for treatment of cancer, belonging to 44 families; from them Compositae and Lamiaceae were the most common. Leaves and fruits were the most commonly used parts, while decoctions, infusions and syrups were the main methods of preparation. Lung cancer was the most common type of cancer treated with these plants and Ephedra alata was the most commonly used plant for treatment of cancer in Palestine. The Fic was high for all the plants; Fl was 100% for many plants, the highest UV (0.72) was for Ephedra alata. This study showed that many herbal remedies are still used by herbalists in Palestine for treatment of cancer; some of them have been approved scientifically while others are not. A combined effort between informants and scientific institutions working in this field can help in the discovery of new anticancer agents. Moreover, scientists must explore the most suitable method of extraction, formulation and dose determination in order to achieve the best benefits from these herbals.

Treatment switching commonly occurs in clinical trials of novel interventions in the advanced or metastatic cancer setting. However, methods to adjust for switching have been used inconsistently and potentially inappropriately in health technology assessments (HTAs). We present recommendations on the use of methods to adjust survival estimates in the presence of treatment switching in the context of economic evaluations. We provide background on the treatment switching issue and summarize methods used to adjust for it in HTAs. We discuss the assumptions and limitations associated with adjustment methods and draw on results of a simulation study to make recommendations on their use. We demonstrate that methods used to adjust for treatment switching have important limitations and often produce bias in realistic scenarios. We present an analysis framework that aims to increase the probability that suitable adjustment methods can be identified on a case-by-case basis. We recommend that the characteristics of clinical trials, and the treatment switching mechanism observed within them, should be considered alongside the key assumptions of the adjustment methods. Key assumptions include the "no unmeasured confounders" assumption associated with the inverse probability of censoring weights (IPCW) method and the "common treatment effect" assumption associated with the rank preserving structural failure time model (RPSFTM). The limitations associated with switching adjustment methods such as the RPSFTM and IPCW mean that they are appropriate in different scenarios. In some scenarios, both methods may be prone to bias; "2-stage" methods should be considered, and intention-to-treat analyses may sometimes produce the least bias. The data requirements of adjustment methods also have important implications for clinical trialists.

Considering the large quantities of wastewater generated from iron and steel enterprises in China, this paper is aimed to research the common methods applied for evaluating the integrated wastewater treatment effect of iron and steel enterprises. Based on survey results on environmental protection performance, technological economy, resource & energy consumption, services and management, an indicator system for evaluating the operation effect of integrated wastewater treatment facilities is set up. By discussing the standards and industrial policies in and out of China, 27 key secondary indicators are further defined on the basis of investigation on main equipment and key processes for wastewater treatment, so as to determine the method for setting key quantitative and qualitative indicators for evaluation indicator system. It is also expected to satisfy the basic requirements of reasonable resource allocation, environmental protection and sustainable economic development, further improve the integrated wastewater treatment effect of iron and steel enterprises, and reduce the emission of hazardous substances and environmental impact.

In the sub-Saharan African setting, laparotomy for salpingectomy is the common method of treatment for ectopic pregnancy (EP). The objective of this retrospective study was to find out how common EP is treated conservatively in the Yaounde Gynaeco-Obstetric and Paediatric Hospital, Cameroon. Of the 281 patient files analysed, 126 patients (44.8%) were treated conservatively and successfully for EP. Of these, 86 (68.2%) had received conservative surgical treatment while 40 (31.8%) had non-surgical treatment. Salpingostomy was the conservative surgery for 79.1% of the cases. According to the publications available for the sub-Saharan setting, the rate of conservative management of EP at the Yaounde Gynaeco-Obstetric and Paediatric Hospital, Cameroon is high. We recommend that this rate should be improved so that, eventually, the conservative treatment methods of EP become routine.

Colorectal cancer is a common malignancy that most commonly metastasizes to the liver. There has been considerable effort in developing new treatment options for these patients. One method that has been developed for the treatment of colorectal metastases to the liver is irinotecan-loaded drug-eluting bead (DEBIRI) embolization. This article reviews the current literature on DEBIRI and discusses the state of current knowledge and possible areas of future investigation.

Background To examine barriers to initiation and continuation of mental health treatment among individuals with common mental disorders. Methods Data are from the WHO World Mental Health (WMH) Surveys. Representative household samples were interviewed face-to-face in 24 countries. Reasons to initiate and continue treatment were examined in a subsample (n= 63,678) and analyzed at different levels of clinical severity. Results Among those with a DSM-IV disorder in the past twelve months, low perceived need was the most common reason for not initiating treatment and more common among moderate and mild than severe cases. Women and younger people with disorders were more likely to recognize a need for treatment. Desire to handle the problem on one’s own was the most common barrier among respondents with a disorder who perceived a need for treatment (63.8%). Attitudinal barriers were much more important than structural barriers both to initiating and continuing treatment. However, attitudinal barriers dominated for mild-moderate cases and structural barriers for severe cases. Perceived ineffectiveness of treatment was the most commonly reported reason for treatment dropout (39.3%) followed by negative experiences with treatment providers (26.9% of respondents with severe disorders). Conclusions Low perceived need and attitudinal barriers are the major barriers to seeking and staying in treatment among individuals with common mental disorders worldwide. Apart from targeting structural barriers, mainly in countries with poor resources, increasing population mental health literacy is an important endeavor worldwide. PMID:23931656

There are limited existing data describing the training methods used to educate tobacco cessation treatment providers around the world. To measure the prevalence of tobacco cessation treatment content, skills training and teaching methods reported by tobacco treatment training programs across the world. Web-based survey in May-September 2013 among tobacco cessation training experts across six geographic regions and four World Bank income levels. Response rate was 73% (84 of 115 countries contacted). Of 104 individual programs from 84 countries, most reported teaching brief advice (78%) and one-to-one counseling (74%); telephone counseling was uncommon (33%). Overall, teaching of knowledge topics was more commonly reported than skills training. Programs in lower income countries less often reported teaching about medications, behavioral treatments and biomarkers and less often reported skills-based training about interviewing clients, medication management, biomarker measurement, assessing client outcomes, and assisting clients with co-morbidities. Programs reported a median 15 hours of training. Face-to-face training was common (85%); online programs were rare (19%). Almost half (47%) included no learner assessment. Only 35% offered continuing education. Nearly all programs reported teaching evidence-based treatment modalities in a face-to-face format. Few programs delivered training online or offered continuing education. Skills-based training was less common among low- and middle-income countries (LMICs). There is a large unmet need for tobacco treatment training protocols which emphasize practical skills, and which are more rapidly scalable than face-to-face training in LMICs.
[Reflexology--nothing in common with scientific naturopathic treatments].
Heide, M; Heide, M H
2009-09-01
A host of alternative treatment methods are sold to us as reputable science on the "supermarket of naturopathy" nowadays. "Foot zone therapy", also known as "reflexology" is one of them. Advocates of reflexology claim that certain zones of the feet are linked to internal organs; that "energy forces" run throughout the human body. According to the teachings of Ayurveda and Yoga, a network of more than 72,000 nerve tracts (energy tracts = meridians) is linked to a single, tiny point on the feet, where the energy ends. In reality, however, reflexology is an unconventional, alternative, paramedical and esoterical "outsider" method that has nothing in common with serious naturopathic treatments. Any scientific value to reflexology is to be denied. As opposed to reflexology, genuine, scientifically acknowledged naturopathic methods are not an alternative, but a supplement to modern medicine.

Treatment of pediatric burn patients is very important because of the sheer frequency of burn wounds and the possible long-term ramifications. Extensive burns need special care and are treated in specialized burn centers. The goal of this work is to present current standards in burn therapy and important innovations in the treatment of burns in children so that the common and small area burn wounds and scalds in pediatric patients in day-to-day dermatological practice can be adequately treated. Analysis of current literature, discussion of reviews, incorporation of current guidelines. Burns in pediatric patients are common. Improvement of survival can be achieved by treatment in burn centers. The assessment of burn depth and area is an important factor for proper treatment. We give an overview for outpatient treatment of partial thickness burns. New methods may result in better long-term outcome. Adequate treatment of burn injuries considering current literature and guidelines improves patient outcome. Rational implementation of new methods is recommended.
A Causal Model for Joint Evaluation of Placebo and Treatment-Specific Effects in Clinical Trials
Zhang, Zhiwei; Kotz, Richard M.; Wang, Chenguang; Ruan, Shiling; Ho, Martin
2014-01-01
Summary Evaluation of medical treatments is frequently complicated by the presence of substantial placebo effects, especially on relatively subjective endpoints, and the standard solution to this problem is a randomized, double-blinded, placebo-controlled clinical trial. However, effective blinding does not guarantee that all patients have the same belief or mentality about which treatment they have received (or treatmentality, for brevity), making it difficult to interpret the usual intent-to-treat effect as a causal effect. We discuss the causal relationships among treatment, treatmentality and the clinical outcome of interest, and propose a causal model for joint evaluation of placebo and treatment-specific effects. The model highlights the importance of measuring and incorporating patient treatmentality and suggests that each treatment group should be considered a separate observational study with a patient's treatmentality playing the role of an uncontrolled exposure. This perspective allows us to adapt existing methods for dealing with confounding to joint estimation of placebo and treatment-specific effects using measured treatmentality data, commonly known as blinding assessment data. We first apply this approach to the most common type of blinding assessment data, which is categorical, and illustrate the methods using an example from asthma. We then propose that blinding assessment data can be collected as a continuous variable, specifically when a patient's treatmentality is measured as a subjective probability, and describe analytic methods for that case.

Orogastric gavage, while a common method for delivering experimental substances in mice, has been shown to induce stress. To minimize the associated stress with this procedure, sham gavage prior to the start of experiment is a common method for habiutating mice. We investigated whether handling and restraint could replace sham treatment in the acclimatization protocol. Mice were either undisturbed, hand-restrained for 10 s or sham-gavaged daily for six days prior to eight days of twice daily gavage. The results showed that repetitive restraint and gavage had no differences in body weight after eight days of treatment compared with the body weights at the start of treatment, whereas animals left undisturbed lost significant weight once treatment began. These data suggest that procedure refinement by replacing sham treatment with hand restraint is sufficient to acclimatize mice to the stress associated with gavage. © The Author(s) 2016.

The authors examined consumer outcomes before and after implementing CommonGround, a computer-based shared decision-making program. Consumers with severe mental illness (N=167) were interviewed prior to implementation and 12 and 18 months later to assess changes in active treatment involvement, symptoms, and recovery-related attitudes. Providers also rated consumers on level of treatment involvement. Most consumers used CommonGround at least once (67%), but few used the program regularly. Mixed-effects regression analyses showed improvement in self-reported symptoms and recovery attitudes. Self-reported treatment involvement did not change; however, for a subset of consumers with the same providers over time (N=83), the providers rated consumers as more active in treatment. This study adds to the growing literature on tools to support shared decision making, showing the potential benefits of CommonGround for improving recovery outcomes. More work is needed to better engage consumers in CommonGround and to test the approach with more rigorous methods.

BACKGROUND: Common warts are skin diseases caused by human papillomavirus. Several treatment modalities available for common warts, two of them are electrodesiccation with curettage and application of 80% phenol solution. AIM: This study aims to compare clinical efficacy between these two modalities. MATERIAL AND METHODS: Open clinical trial was conducted at Dr Pirngadi General Hospital Medan and H. Adam Malik General Hospital Medan from February to June 2013 on 17 patients with multiple common warts. Both treatments began and applied simultaneously on the same day on each patient. RESULTS: Cure rate was higher in electrodesiccation with curettage (76.5%, 100%) compared to the application of 80% phenol solution (11.8%, 64.7%) on three weeks and six weeks of follow up. Statistical analysis showed a significant difference of common warts cure rate between electrodesiccation with curettage and application of 80% phenol solution after three weeks (p < 0.001) and six weeks (p = 0.018) of treatment. CONCLUSION: As a conclusion, electrodesiccation with curettage has higher cure rate than the application of 80% phenol solution on the treatment of common warts. Further study is needed to find out the best concentration and time interval for application of phenol solution to improve its clinical efficacy as an alternative treatment of choice for common warts.

Agitation episodes are common among patients with schizophrenia or bipolar disorder. Oral and intramuscular administration methods are commonly used in pharmacological treatment of acute agitation. Recently, an innovative inhalation product with loxapine(Adasuve®)has become available for treatment of acute agitation episodes associated with bipolar disorder or schizophrenia. The objective for the present study was to investigate the impact of the pharmacological treatment's administration methods on the health-related quality of life (HRQoL) in patients with bipolar disorder or schizophrenia in Denmark and Sweden using a time trade-off (TTO) approach. The TTO methodology was used to examine the HRQoL impact of administration method of pharmacological treatment of acute agitation. Data were collected via an internet-based survey, using an existing panel of respondents with schizophrenia or bipolar disorder. Respondents considered living with schizophrenia/ bipolar disorder, having one yearly agitation episode treated with inhaler better than living with the same conditions and receiving treatment with tablet or injection. The utility value was 0.762 for inhalable treatment, 0.707 for injection and 0.734 for tablet treatment. Patients' preference for treatment delivery options showed that inhalation was associated with a significant utility gain when compared to injection or tablets. Inhalable loxapine may be a new tool for control of agitation episodes for strengthening the patient provider alliance when taking patient's preference for delivery method into consideration.

To investigate the cognition of the common cold and current situation of the treatment among physicians from various levels of hospitals in Chinese mainland, so as to provide evidence for future continuing medical education and rational medication. A questionnaire designed for this survey was used to learn about the general information, cognitive degree of the common cold and prescription habits of physician who prescribed for cold within last three months, from various levels hospitals. A total of 1001 physicians were interviewed. Among them, 749 physicians chose right options that the cold was the common cold and the influenza with 79.84% in resident physicians and 56.76% in chief physicians. A total of 745 physicians chose options that the course of common cold will be lasting 4 to 7 days; 895 physicians chose options that old people are the most susceptible for complication; 669 physicians thought the common cold was the most common infection in winter; 841 physicians used clinical methods to diagnose the common cold; 736 physicians thought although the cold was a kind of self-limited disease and symptomatic treatment could alleviate symptoms and improve life quality, patients should see doctor in time if it turns to severer; and 745 physicians held the opinion that treatment of the common cold should focus on relieving symptoms first. In addition, 61.60% physicians had made prescription based on clinical symptoms; 505 (54.24%) of them thought compound drugs were priority in treating the common cold. However, there were still 43 physicians prescribed antibiotics for common cold. There is misunderstanding and discrepancy in cognition towards common cold and treatment among physicians from various levels of hospitals in mainland China. Physicians should standardize diagnosis and treatment for the common cold according to the domestic and foreign guidelines.
[Thought and method of classic formulae in treatment of chronic cough].
Su, Ke-Lei; Zhang, Ye-Qing
2018-06-01
Chronic cough is a common clinical disease with complex etiology, which is easily misdiagnosed and mistreated. Chronic cough guideline has been developed based on the modern anatomical etiology classification, and it may improve the level of diagnosis and treatment. Common causes of chronic cough are as follows: cough variant asthma, upper airway cough syndrome, eosinophilic bronchitis, gastroesophageal reflux-related cough, post-infectious cough, etc. There is a long history and rich experience in treatment of cough in traditional Chinese medicine which is characterized by syndrome differentiation. The four elements of pathogenesis for chronic cough include wind, phlegm, fire, and deficiency. Classic formula is widely used in the treatment of chronic cough, and the focus is on prescriptions corresponding to syndromes. This article attempts to explore the thought and method of classic formulae in treatment of chronic cough based on three perspectives: differentiation of etiology, pathogenesis and formula-syndrome. Three medical cases are selected at last in order to prove its correction. Copyright© by the Chinese Pharmaceutical Association.

Fever is a common symptom of childhood illness, and much time and effort is spent in the pursuit of reducing high temperature. Although antipyretic drugs are the main form of treatment, this report considers the part that physical treatments might play in reducing the temperature of febrile children. Such treatments include tepid sponging, removing clothing, and cooling the environment. Of these treatments, tepid sponging has been studied most extensively, as an addition to paracetamol, but seems to offer little advantage over paracetamol alone. It is likely that other methods might be equally ineffective because they all rely on similar methods of heat loss. PMID:10685930

The degradation behavior of veterinary antibiotics in soil is commonly studied using the following methods of adding antibiotics to the soil: (i) adding manure collected from animals fed with a diet containing antibiotics, (ii) adding antibiotic-free animal manure spiked with antibiotics and (iii) directly adding antibiotics. No research simultaneously comparing different antibiotic addition methods was found. Oxytetracycline (OTC) was used as a model antibiotic to compare the effect of the three commonly used antibiotic addition methods on OTC degradation behavior in soil. The three treatment methods have similar trends, though OTC degradation half-lives show the following significant differences (P<0.05): manure from swine fed OTC (treatment A)

Internet-delivered treatment has the potential to expand access to evidence-based cognitive-behavioral therapy (CBT) for pediatric headache, and has demonstrated efficacy in small trials for some youth with headache. We used a mixed methods approach to identify effective components of CBT for this population. In Study 1, component profile analysis identified common interventions delivered in published RCTs of effective CBT protocols for pediatric headache delivered face-to-face or via the Internet. We identified a core set of three treatment components that were common across face-to-face and Internet protocols: 1) headache education, 2) relaxation training, and 3) cognitive interventions. Biofeedback was identified as an additional core treatment component delivered in face-to-face protocols only. In Study 2, we conducted qualitative interviews to describe the perspectives of youth with headache and their parents on successful components of an Internet CBT intervention. Eleven themes emerged from the qualitative data analysis, which broadly focused on patient experiences using the treatment components and suggestions for new treatment components. In the Discussion, these mixed methods findings are integrated to inform the adaptation of an Internet CBT protocol for youth with headache. PMID:29503787

Internet-delivered treatment has the potential to expand access to evidence-based cognitive-behavioral therapy (CBT) for pediatric headache, and has demonstrated efficacy in small trials for some youth with headache. We used a mixed methods approach to identify effective components of CBT for this population. In Study 1, component profile analysis identified common interventions delivered in published RCTs of effective CBT protocols for pediatric headache delivered face-to-face or via the Internet. We identified a core set of three treatment components that were common across face-to-face and Internet protocols: 1) headache education, 2) relaxation training, and 3) cognitive interventions. Biofeedback was identified as an additional core treatment component delivered in face-to-face protocols only. In Study 2, we conducted qualitative interviews to describe the perspectives of youth with headache and their parents on successful components of an Internet CBT intervention. Eleven themes emerged from the qualitative data analysis, which broadly focused on patient experiences using the treatment components and suggestions for new treatment components. In the Discussion, these mixed methods findings are integrated to inform the adaptation of an Internet CBT protocol for youth with headache.

[Brain abscess--modern diagnostics and therapeutic treatment].
Kalinowska-Nowak, Anna; Garlicki, Aleksander; Bociaga-Jasik, Monika
2009-01-01
Brain abscess is one of the most serious diseases of the central nervous system. This condition is more common among men--twice to three times, and morbidity rate is highest in fourth decade of the life. Etiologic agents of brain abscess are bacteria, fungus, protozoa and parasites. The development of the brain abscess can resulted from the spread of infection from local sites or bloodborne from distal sites. In 10-15% of cases multiple abscesses develop. Headache is the most common syndrome. The radiologic tests: computed tomography or magnetic resonance are tests of choice in diagnosis and monitoring of treatment. Treatment of brains abscesses required cooperation of different specialists: infectious diseases, neuroradiologist, neurologists and neurosurgeon. Decision about therapeutic methods depends on number, size and localization of lesions, and patient's condition. In conservative treatment empiric antibiotic therapy and supportive treatment are used. Actually two methods of surgical treatment are used: CT- guided stereotactic aspiration and incision of the brain abscess by craniotomy. Actually mortality rate is 6 to 24%. Among 30-56% patients permanent neurological complications are reported.

Oral and intravenous (IV) acetylcysteine are used for treatment of acetaminophen poisoning. The objective of this multi-center study was to compare the safety of these two routes of administration. METHODS We conducted a multi-center chart review of all patients treated with acetylcysteine for acetaminophen poisoning. The primary safety outcome was the percentage of patients with of acetylcysteine-related adverse events. RESULTS A total of 503 subjects were included in the safety analysis (306 IV only, 145 oral only and 52 both routes).There were no serious adverse events related to acetylcysteine for either route. Nausea and vomiting were the most common related adverse events and were more common with oral treatment (23% vs 9%). Anaphylactoid reactions were more common with IV administration (6% vs 2%). Conclusions Intravenous and oral acetylcysteine are both associated with minimal side effects and are safe for treatment of acetaminophen toxicity. PMID:20524832
Treatment of lithium intoxication: facing the need for evidence.
Haussmann, R; Bauer, M; von Bonin, S; Grof, P; Lewitzka, U
2015-12-01
Lithium has been used as the gold standard in the treatment of major depressive and bipolar disorders for decades. Due to its narrow therapeutic index, lithium toxicity is a common clinical problem. Although risk factors for lithium intoxication seem to be well-described, lacking patient education and inexperience of treatment are assumed to contribute to the probability of lithium intoxication. A review of literature shows that the treatment of lithium intoxication has not been adequately studied or standardized. The aim of this literature review is to compile and present current evidence on the treatment of lithium intoxication and contribute to a standardization regarding general treatment recommendations as well as evidence on indication for extracorporeal methods. Against the background of this common and potentially life-threatening condition, the standardization of the treatment of lithium intoxication is definitely a task for the future.
Tuberculous otitis media -- a diagnostic dilemma.
Bhalla, R K; Jones, T M; Rothburn, M M; Swift, A C
2001-08-01
Tuberculous otitis media can provide a diagnostic challenge even to the most astute and experienced clinician. The rarity of the condition and its propensity to masquerade as commoner otological conditions further delays diagnosis and treatment. We present the case of a 22-year-old female who presented with chronic aural discharge, unilateral hearing loss and recurrent hemifacial paralysis. The paper highlights the difficulty in diagnosis and stresses the need for a high index of suspicion in cases resistant to the common methods of treatment.

Background The common cold, the most prevalent contagious viral disease in humans still lacks a safe and effective antiviral treatment. Iota-Carrageenan is broadly active against respiratory viruses in-vitro and has an excellent safety profile. This study investigated the efficacy and safety of an Iota-Carrageenan nasal spray in patients with common cold symptoms. Methods In a randomized, double-blind, placebo-controlled exploratory trial, 35 human subjects suffering from early symptoms of common cold received Iota-Carrageenan (0.12%) in a saline solution three times daily for 4 days, compared to placebo. Results Administration of Iota-Carrageenan nasal spray reduced the symptoms of common cold (p = 0.046) and the viral load in nasal lavages (p = 0.009) in patients with early symptoms of common cold. Pro-inflammatory mediators FGF-2, Fractalkine, GRO, G-CSF, IL-8, IL-1α, IP-10, IL-10, and IFN-α2 were reduced in the Iota-Carrageenan group. Conclusions Iota-Carrageenan nasal spray appears to be a promising treatment for safe and effective treatment of early symptoms of common cold. Larger trials are indicated to confirm the results.

Background This report is the SOSORT Consensus Paper on Terminology for use in the treatment of conservative spinal deformities. Figures are provided and relevant literature is cited where appropriate. Methods The Delphi method was used to reach a preliminary consensus before the meeting, where the terms that still needed further clarification were discussed. Results A final agreement was found for all the terms, which now constitute the base of this glossary. New terms will be added after being discussed and accepted. Discussion When only one set of terms is used for communication in a place or among a group of people, then everyone can clearly and efficiently communicate. This principle applies for any professional group. Until now, no common set of terms was available in the field of the conservative treatment of scoliosis and spinal deformities. This glossary gives a common base language to draw from to discuss data, findings and treatment. PMID:21044334
Monte Carlo simulations in radiotherapy dosimetry.
Andreo, Pedro
2018-06-27
The use of the Monte Carlo (MC) method in radiotherapy dosimetry has increased almost exponentially in the last decades. Its widespread use in the field has converted this computer simulation technique in a common tool for reference and treatment planning dosimetry calculations. This work reviews the different MC calculations made on dosimetric quantities, like stopping-power ratios and perturbation correction factors required for reference ionization chamber dosimetry, as well as the fully realistic MC simulations currently available on clinical accelerators, detectors and patient treatment planning. Issues are raised that include the necessity for consistency in the data throughout the entire dosimetry chain in reference dosimetry, and how Bragg-Gray theory breaks down for small photon fields. Both aspects are less critical for MC treatment planning applications, but there are important constraints like tissue characterization and its patient-to-patient variability, which together with the conversion between dose-to-water and dose-to-tissue, are analysed in detail. Although these constraints are common to all methods and algorithms used in different types of treatment planning systems, they make uncertainties involved in MC treatment planning to still remain "uncertain".

Maxillofacial fractures are encountered less commonly during childhood period due to anatomic, social, cultural, and environmental factors. Although the incidence of all maxillofacial fractures is 1% to 15% among pediatric and adolescent patients, this rate drops to less than 1% in children below 5 years age.

Embolization of a large, symptomatic splenic artery pseudoaneurysm
Kukliński, Adam; Batycki, Krzysztof; Matuszewski, Wiesław; Ostrach, Andrzej; Kupis, Zbigniew; Łęgowik, Tomasz
2014-01-01
Summary Background Splenic artery aneurysm is the third most common abdominal aneurysm. Most often it is due to pancreatitis. There were only 19 cases of aneurysms larger than 5 cm in diameter described in the literature. Management of splenic artery aneurysms depends on the size and symptoms. Invasive treatment modalities involve open procedures and interventional radiology methods (endovascular). Case Reports A 44-years-old male with chronic pancreatitis, in a gradually worsening general condition due to a large splenic artery aneurysm, was subjected to the procedure. Blood flow through the aneurysm was cut-off by implanting a covered stent between celiac trunk and common hepatic artery. Patient’s general condition rapidly improved, allowing discharge home in good state soon after the procedure. Conclusions Percutaneous embolization appears to be the best method of treatment of large splenic artery aneurysms. Complications of such treatment are significantly less dangerous than those associated with surgery. PMID:25009678
[Integrative approach in the psychotherapy of borderline personality disorder].
Kuritárné Szabó, Ildikó
2012-01-01
In the last 20 years six psychotherapy methods have been developed specifically for borderline personality disorder. Solid RCT evidences suggests the efficacy of all the methods. Roughly equivalent improvement was obtained from the different types of psychotherapies. Today we have reached a new phase of the borderline "psychotherapy boom", the integrative approach. According to the integrative treatment advocates we should not choose among these effective treatments but we can incorporate in the therapy all the components that work. The integrative approach uses general factors common to all effective therapies, combined with specific treatment techniques taken from different therapies in order to treat the given patient's psychopathology. These common factors are: coherent framework; attention to strategies for building strong positive alliance and maintaining patient motivation; creating a safe and structured therapeutic environment; clear treatment frame; transparency of the goals and roles; focus upon presenting problems; higher level therapeutic activity; here-and-now focus; and facilitating self-reflection. Treatment focuses on change while maintaining a validating and supportive stance. General strategies can be supplemented by more specific techniques such as cognitive-behavioral interventions for reducing maladaptive behavior, training for developing emotion regulation skills and interpersonal skills coming from dialectical behavior therapy. Methods drawn from psychodynamic approaches can be used for the modification of underlying interpersonal cognitive-emotional schemas.
Phenomenology and treatment of selective mutism.
Kumpulainen, Kirsti
2002-01-01
Selective mutism is a multidimensional childhood disorder in which, according to the most recent studies, biologically mediated temperament and anxiety components seem to play a major role. Several psychotherapy methods have been reported in case studies to be useful, but the disorder is commonly seen to be resistant to change, particularly in cases of long duration. Currently, behaviour modification and other cognitive methods, together with cooperation with the family and the school personnel, are recommended in the treatment of selective mutism. Selective serotonin reuptake inhibitors and selective monoamine oxidase inhibitors have also been reported to be helpful when treating children with selective mutism. At the moment, pharmacotherapy cannot be recommended as the treatment of first choice but if other methods of treatment are not helpful, medication can be included in the treatment scheme. Comprehensive evaluation and treatment of possible primary and comorbid problems that require treatment are also essential.

Background Missing cases following treatment are common in Web-based psychotherapy trials. Without the ability to directly measure and evaluate the outcomes for missing cases, the ability to measure and evaluate the effects of treatment is challenging. Although common, little is known about the characteristics of Web-based psychotherapy participants who present as missing cases, their likely clinical outcomes, or the suitability of different statistical assumptions that can characterize missing cases. Objective Using a large sample of individuals who underwent Web-based psychotherapy for depressive symptoms (n=820), the aim of this study was to explore the characteristics of cases who present as missing cases at posttreatment (n=138), their likely treatment outcomes, and compare between statistical methods for replacing their missing data. Methods First, common participant and treatment features were tested through binary logistic regression models, evaluating the ability to predict missing cases. Second, the same variables were screened for their ability to increase or impede the rate symptom change that was observed following treatment. Third, using recontacted cases at 3-month follow-up to proximally represent missing cases outcomes following treatment, various simulated replacement scores were compared and evaluated against observed clinical follow-up scores. Results Missing cases were dominantly predicted by lower treatment adherence and increased symptoms at pretreatment. Statistical methods that ignored these characteristics can overlook an important clinical phenomenon and consequently produce inaccurate replacement outcomes, with symptoms estimates that can swing from −32% to 70% from the observed outcomes of recontacted cases. In contrast, longitudinal statistical methods that adjusted their estimates for missing cases outcomes by treatment adherence rates and baseline symptoms scores resulted in minimal measurement bias (<8%). Conclusions Certain variables can characterize and predict missing cases likelihood and jointly predict lesser clinical improvement. Under such circumstances, individuals with potentially worst off treatment outcomes can become concealed, and failure to adjust for this can lead to substantial clinical measurement bias. Together, this preliminary research suggests that missing cases in Web-based psychotherapeutic interventions may not occur as random events and can be systematically predicted. Critically, at the same time, missing cases may experience outcomes that are distinct and important for a complete understanding of the treatment effect. PMID:29674311
Active treatments for amblyopia: a review of the methods and evidence base.
Suttle, Catherine M
2010-09-01
Treatment for amblyopia commonly involves passive methods such as occlusion of the non-amblyopic eye. An evidence base for these methods is provided by animal models of visual deprivation and plasticity in early life and randomised controlled studies in humans with amblyopia. Other treatments of amblyopia, intended to be used instead of or in conjunction with passive methods, are known as 'active' because they require some activity on the part of the patient. Active methods are intended to enhance treatment of amblyopia in a number of ways, including increased compliance and attention during the treatment periods (due to activities that are interesting for the patient) and the use of stimuli designed to activate and to encourage connectivity between certain cortical cell types. Active methods of amblyopia treatment are widely available and are discussed to some extent in the literature, but in many cases the evidence base is unclear, and effectiveness has not been thoroughly tested. This review looks at the techniques and evidence base for a range of these methods and discusses the need for an evidence-based approach to the acceptance and use of active amblyopia treatments.

Sulfadimidine (SM2) is commonly used in the swine industry and enters the environment via faeces. In recent years, advances in the ecotoxicology of SM2 have become a popular research interest with two common research methods including swine manure collection from swine fed with a diet containing SM2 and directly adding SM2. The purpose of this experiment was to compare SM2 degradation behaviour in pig manure with two different SM2 addition methods. The results showed that the degradation half-lives of SM2 in manure from SM2-fed swine treatment were 33.2 and 32.0 days at the initial addition level of SM2 at 32.1 and 64.3 mg/kg, respectively. This was significantly longer than that in manure directly adding SM2 treatment with the half-lives of 21.4 and 14.8 days. The metabolite of SM2 N 4 -acetyl-sulfamethazine occurred in manure from SM2-fed swine treatment but was not detected in directly adding SM2 treatment. The pH in manure from SM2-fed swine treatment was significantly lower than that in directly adding SM2 treatment, but the values of organic carbon, total nitrogen, and electrical conductivity in manure from SM2-fed swine treatment were significantly higher than those in manure directly adding SM2 treatment. Meanwhile, although the copy number of bacteria had no significant difference between two treatments, there was a significant difference in bacteria diversity. Results of the present study demonstrated that the presence of the metabolites, chemical property, and microbial diversity might be the reason for different SM2 degradation behaviours on different addition methods. Thus, the method using manure with SM2 collected from swine could obtain more accurate results for the ecotoxicological study of SM2.

Pain in infancy and childhood is extremely common. Sources of pain include illness, injury, and medical and dental procedures. Over the past two decades, tremendous progress has been made in the assessment, prevention and treatment of pain. It is important for the paediatric health care provider to be aware of the implications and consequences of pain in childhood. A multitude of interventions are available to reduce or alleviate pain in children of all ages, including neonates. These include behavioural and psychological methods, as well as a host of pharmacological preparations, which are safe and effective when used as indicated. Many complementary and alternative treatments appear to be promising in treating and relieving pain, although further research is required. The present article reviews the most common sources of pain in childhood and infancy, as well as current treatment strategies and options. PMID:19030348

Describe the experience that girls with Rett syndrome have with menstruation including menstrual hygiene, dysmenorrhea, premenstrual syndrome (PMS), and attempts at treatment. Anonymous web-based survey. Convenience sample recruited from Rett syndrome LISTSERV in July of 2009. Mothers of girls with Rett syndrome between the ages of 10-25 who have had at least one menses. Prevalence, frequency, and severity of dysmenorrhea and PMS; hygiene concerns; and treatments attempts and perceived effectiveness. Dysmenorrhea and PMS are common problems among young women with Rett syndrome. Despite their frequency and severity they do not routinely limit activities. Multiple treatment attempts are common. Hormonal contraception is used mostly for menstrual cycle control with oral contraceptive pills the most commonly used method. Young women with Rett syndrome have standard symptoms of dysmenorrhea and PMS as well as autism spectrum specific PMS symptoms. Hormonal contraception is commonly used for menstrual management.

Empirical Likelihood-Based Estimation of the Treatment Effect in a Pretest-Posttest Study.
Huang, Chiung-Yu; Qin, Jing; Follmann, Dean A
2008-09-01
The pretest-posttest study design is commonly used in medical and social science research to assess the effect of a treatment or an intervention. Recently, interest has been rising in developing inference procedures that improve efficiency while relaxing assumptions used in the pretest-posttest data analysis, especially when the posttest measurement might be missing. In this article we propose a semiparametric estimation procedure based on empirical likelihood (EL) that incorporates the common baseline covariate information to improve efficiency. The proposed method also yields an asymptotically unbiased estimate of the response distribution. Thus functions of the response distribution, such as the median, can be estimated straightforwardly, and the EL method can provide a more appealing estimate of the treatment effect for skewed data. We show that, compared with existing methods, the proposed EL estimator has appealing theoretical properties, especially when the working model for the underlying relationship between the pretest and posttest measurements is misspecified. A series of simulation studies demonstrates that the EL-based estimator outperforms its competitors when the working model is misspecified and the data are missing at random. We illustrate the methods by analyzing data from an AIDS clinical trial (ACTG 175).

Estimating intervention effects of prevention programs: Accounting for noncompliance
Stuart, Elizabeth A.; Perry, Deborah F.; Le, Huynh-Nhu; Ialongo, Nicholas S.
2010-01-01
Individuals not fully complying with their assigned treatments is a common problem encountered in randomized evaluations of behavioral interventions. Treatment group members rarely attend all sessions or do all “required” activities; control group members sometimes find ways to participate in aspects of the intervention. As a result, there is often interest in estimating both the effect of being assigned to participate in the intervention, as well as the impact of actually participating and doing all of the required activities. Methods known broadly as “complier average causal effects” (CACE) or “instrumental variables” (IV) methods have been developed to estimate this latter effect, but they are more commonly applied in medical and treatment research. Since the use of these statistical techniques in prevention trials has been less widespread, many prevention scientists may not be familiar with the underlying assumptions and limitations of CACE and IV approaches. This paper provides an introduction to these methods, described in the context of randomized controlled trials of two preventive interventions: one for perinatal depression among at-risk women and the other for aggressive disruptive behavior in children. Through these case studies, the underlying assumptions and limitations of these methods are highlighted. PMID:18843535

INTRODUCTION: Hair loss is a common complaint seen in dermatology clinics. From frustration and attempts at self-help, patients with hair loss may present to the dermatologist with false beliefs, or myths, about the causes of their condition and what treatments are effective.
METHODS: We identified 12 common myths about hair loss, categorized as myths about minoxidil treatment, vitamin and mineral supplements, natural topical treatments, and hair care practices. We performed a PubMed search to find evidence to support or refute each myth.
RESULTS: We found that there is little evidence to support many of these common hair loss myths. In some cases, randomized controlled trials have investigated the effects of particular therapies and point to the effectiveness of certain hair loss treatments.
DISCUSSION: In many cases, there have not been sufficient randomized controlled trials to evaluate the effect of different therapies and hair care practices on hair loss. It is best to guide patients toward treatments with a long track record of efficacy and away from those where little is known scientifically.

Hypertrophic scars, resulting from alterations in the normal processes of cutaneous wound healing, are characterized by proliferation of dermal tissue with excessive deposition of fibroblast-derived extracellular matrix proteins, especially collagen, over long periods, and by persistent inflammation and fibrosis. Hypertrophic scars are among the most common and frustrating problems after injury. As current aesthetic surgical techniques become more standardized and results more predictable, a fine scar may be the demarcating line between acceptable and unacceptable aesthetic results. However, hypertrophic scars remain notoriously difficult to eradicate because of the high recurrence rates and the incidence of side effects associated with available treatment methods. This review explores the various treatment methods for hypertrophic scarring described in the literature including evidence-based therapies, standard practices, and emerging methods, attempting to distinguish those with clearly proven efficiency from anecdotal reports about therapies of doubtful benefits while trying to differentiate between prophylactic measures and actual treatment methods. Unfortunately, the distinction between hypertrophic scar treatments and keloid treatments is not obvious in most reports, making it difficult to assess the efficacy of hypertrophic scar treatment.

Melasma is a common skin condition that affects both men and women. However, it is more commonly seen in women and dark-skinned individuals, such as in Hispanics, Asians, and African Americans who live in areas with intense ultraviolet radiation. Melasma is less common in men, but it negatively affects the quality of life in men as much as it does in women. While melasma has been studied in detail in women, however, there is a paucity of studies on the clinico- etiopathology and therapeutics of melasma in men. This article reviews and discusses important clinical, etiological, and treatment aspects of melasma in men. The authors recommend that clinicians educate their patients on the causes, prevention and treatment methods, and recurrence rates of melasma. The authors also recommend that clinicians take into careful consideration each patient’s preferences and expectations when creating treatment regimens, as these might differ greatly among men and their female counterparts.

One of the most common and serious complications of diabetes mellitus is ulceration of the foot. Among persons with diabetes, 12%-25% will present to a healthcare institution for a foot disorder during their lifespan. Despite currently available medical and surgical treatments, these are still the most common diabetes-related cause of hospitalization and of lower extremity amputations. Thus, many adjunctive and complementary treatments have been developed in an attempt to improve outcomes. We herein review the available literature on the effectiveness of several treatments, including superficial and deep heaters, electro-therapy procedures, prophylactic methods, exercise and shoe modifications, on diabetic foot wounds. Overall, although physical therapy modalities seem to be useful in the treatment of diabetic foot wounds, further randomized clinical studies are required. PMID:25992328

One of the highest priority invasive species at both Yosemite and Sequoia and Kings Canyon national parks is Holcus lanatus L. (common velvetgrass), a perennial bunchgrass that invades mid-elevation montane meadows. Despite velvetgrass being a high priority species, there is little information available on control techniques. The goal of this project was to evaluate the short-term response of a single application of common chemical and manual velvetgrass control techniques. The study was conducted at three montane sites in Yosemite National Park. Glyphosate spot-spray treatments were applied at 0.5, 1.0, 1.5, and 2.0% concentrations, and compared with hand pulling to evaluate effects on cover of common velvetgrass, cover of other plant species, and community species richness. Posttreatment year 1 cover of common velvetgrass was 12.1% ± 1.6 in control plots, 6.3% ± 1.5 averaged over the four chemical treatments (all chemical treatments performed similarly), and 13.6% ± 1.7 for handpulled plots. This represents an approximately 50% reduction in common velvetgrass cover in chemically- treated plots recoded posttreatment year 1 and no statistically significant reduction in hand pulled plots compared with controls. However, there was no treatment effect in posttreatment year 2, and all herbicide application rates performed similarly. In addition, there were no significant treatment effects on nontarget species or species richness. These results suggest that for this level of infestation and habitat type, (1) one year of hand pulling is not an effective control method and (2) glyphosate provides some level of control in the short-term without impact to nontarget plant species, but the effect is temporary as a single year of glyphosate treatment is ineffective over a two-year period.

Background Garlic is alleged to have antimicrobial and antiviral properties that relieve the common cold, among other beneficial effects. There is widespread usage of garlic supplements. The common cold is associated with significant morbidity and economic consequences. On average, children have six to eight colds per year and adults have two to four.Objectives To determine whether garlic (Allium sativum) is effective for the prevention or treatment of the common cold, when compared to placebo, no treatment or other treatments.Search methods We searched CENTRAL (2014, Issue 7),OLDMEDLINE (1950 to 1965),MEDLINE (January 1966 to July week 5, 2014), EMBASE(1974 to August 2014) and AMED (1985 to August 2014).Selection criteria Randomised controlled trials of common cold prevention and treatment comparing garlic with placebo, no treatment or standard treatment.Data collection and analysis Two review authors independently reviewed and selected trials from searches, assessed and rated study quality and extracted relevant data.Main results In this updated review, we identified eight trials as potentially relevant from our searches. Again, only one trial met the inclusion criteria.This trial randomly assigned 146 participants to either a garlic supplement (with 180 mg of allicin content) or a placebo (once daily)for 12 weeks. The trial reported 24 occurrences of the common cold in the garlic intervention group compared with 65 in the placebo group (P value < 0.001), resulting in fewer days of illness in the garlic group compared with the placebo group (111 versus 366). The number of days to recovery from an occurrence of the common cold was similar in both groups (4.63 versus 5.63). Only one trial met the inclusion criteria, therefore limited conclusions can be drawn. The trial relied on self reported episodes of the common cold but was of reasonable quality in terms of randomisation and allocation concealment. Adverse effects included rash and odour. Authors' conclusions There is insufficient clinical trial evidence regarding the effects of garlic in preventing or treating the common cold. A single trial suggested that garlic may prevent occurrences of the common cold but more studies are needed to validate this finding. Claims of effectiveness appear to rely largely on poor-quality evidence.

Patients referred for stomatognathic treatment--a survey of 282 patients.
Magnusson, T
1984-01-01
The signs and symptoms of mandibular dysfunction and the treatment results were studied in 282 patients referred to the Clinic of Stomatognathic Physiology, Luleå, Sweden. Seventy two per cent of the patients were women. The most common clinical finding was muscles tender to palpation, which was found in 60% of the patients, but other signs such as TMJ-clickings (27%) and limited mandibular movement (16%) were common, as were interferences in the retruded position (33%) and on the non-working side (19%). Splint therapy, therapeutic exercises for the lower jaw and occlusal adjustment in combination with counselling were by far the most common modes of therapy. More than half of the patients had completed the course of treatment within four visits and only a few patients needed more than ten visits. Eighty one per cent of the patients reported no or only mild symptoms after treatment but in a few cases fairly severe or very severe symptoms persisted. The investigation shows that most patients referred because of mandibular dysfunction can be cured or improved with relatively simple treatment methods and after a few visits. In some cases, however, the patients need more complex and time-consuming treatment.

Over 1.6 million adolescents in the United States meet criteria for substance use disorders (SUDs). While there are promising treatments for SUDs, adolescents respond to these treatments differentially in part based on the setting in which treatments are delivered. One way to address such individualized response to treatment is through the development of adaptive interventions (AIs): sequences of decision rules for altering treatment based on an individual's needs. This protocol describes a project with the overarching goal of beginning the development of AIs that provide recommendations for altering the setting of an adolescent's substance use treatment. This project has three discrete aims: (1) explore the views of various stakeholders (parents, providers, policymakers, and researchers) on deciding the setting of substance use treatment for an adolescent based on individualized need, (2) generate hypotheses concerning candidate AIs, and (3) compare the relative effectiveness among candidate AIs and non-adaptive interventions commonly used in everyday practice. This project uses a mixed-methods approach. First, we will conduct an iterative stakeholder engagement process, using RAND's ExpertLens online system, to assess the importance of considering specific individual needs and clinical outcomes when deciding the setting for an adolescent's substance use treatment. Second, we will use results from the stakeholder engagement process to analyze an observational longitudinal data set of 15,656 adolescents in substance use treatment, supported by the Substance Abuse and Mental Health Services Administration, using the Global Appraisal of Individual Needs questionnaire. We will utilize methods based on Q-learning regression to generate hypotheses about candidate AIs. Third, we will use robust statistical methods that aim to appropriately handle casemix adjustment on a large number of covariates (marginal structural modeling and inverse probability of treatment weights) to compare the relative effectiveness among candidate AIs and non-adaptive decision rules that are commonly used in everyday practice. This project begins filling a major gap in clinical and research efforts for adolescents in substance use treatment. Findings could be used to inform the further development and revision of influential multi-dimensional assessment and treatment planning tools, or lay the foundation for subsequent experiments to further develop or test AIs for treatment planning.

ABSTRACT Objectives: To evaluate national practice patterns in the treatment of male anterior urethral strictures among Turkish urologists. Materials and Methods: A survey form including 12 questions prepared to determine active Turkish urologists' approach to diagnosis and treatment of the adult urethral stricture (US) were filled out. Based on the survey results, the institutions which 218 urologists work and their years of expertise, methods they used for diagnosis and treatment, whether or not they perform open urethroplasty and timing of open urethroplasty were investigated. Results: Optic internal urethrotomy and dilatation are the most commonly used minimal invasive procedures in treatment of US with the ratios of 93.5% and 63.3% respectively. On the other hand it was seen that urethroplasty was a less commonly used procedure, compared to minimal invasive techniques, with the ratio of 36.7%. Survey results showed us that the number of US cases observed and open urethroplasty procedures performed increases with increasing years of professional experience. Conclusions: As a method demanding special surgical experience and known as a time-consuming and challenging procedure, open urethroplasty will be able to take a greater part in current urological practice with the help of theoretical education and practical courses given by specific centers and experienced authors.

Hwang, Kun; You, Sun Hye
2010-01-01
Purpose: The medical records of these patients were reviewed and analysed to determine the clinical characteristics and treatment of facial bone fractures. Patients and Methods: This is a retrospective study of 2,094 patients with facial bone fractures from various accidents that were treated at the Inha University Hospital from 1996 to 2007. Results: The most common age group was the third decade of life (29%). Males were more common than females (3.98:1). The most common aetiology was violent assault or nonviolent traumatic injury (49.4%). The most common isolated fracture site was the nasal bone (37.7%), followed by the mandible (30%), orbital bones (7.6%), zygoma (5.7%), maxilla (1.3%) and the frontal bone (0.3%). The largest group with complex fractures included the inferior region of the orbital floor and zygomaticomaxilla (14%). Closed reduction was performed in 46.3% of the cases while 39.7% of the cases required open reduction. For open reductions, the most commonly used soft-tissue approach was the intraoral approach (32.3%). The complication rate was 6.4% and the most common complication was hypoesthesia (68.4%) followed by diplopia (25.6%). Conclusion: Long-term collection of epidemiological data regarding facial fractures and concomitant injuries is important for the evaluation of existing preventive measures and useful in the development of new methods of injury prevention and treatment.

Background The common cold and other viral airway infections are highly prevalent in the population, and their treatment often requires the use of medications for symptomatic relief. Paracetamol is as an analgesic and antipyretic; chlorphenamine is an antihistamine; and phenylephrine, a vasoconstrictor and decongestant. This randomized, double-blind, placebo-controlled trial sought to evaluate the efficacy and safety of a fixed-dose combination of paracetamol, chlorphenamine and phenylephrine in the symptomatic treatment of the common cold and flu-like syndrome in adults. Methods This study enrolled 146 individuals aged 18 to 60 years who had moderate to severe flu-like syndrome or common cold. After clinical examination and laboratory tests, individuals were randomly assigned to receive the fixed-dose combination (73) or placebo (73), five capsules per day for 48 to 72 hours. The primary efficacy endpoint was the sum of the scores of 10 symptoms on a four-point Likert-type scale. To evaluate treatment safety, the occurrence of adverse events was also measured. Results Mean age was 33.5 (±9.5) years in the placebo group and 33.8 (±11.5) in the treatment group. There were 55 women and 18 men in the placebo group, and 46 women and 27 men in the treatment group. Comparison of overall symptom scores in the two groups revealed a significantly greater reduction in the treatment group than in the placebo group (p = 0.015). Analysis at the first 13 dose intervals (± 66 h of treatment) showed a greater reduction of symptom scores in the treatment group than in the placebo group (p < 0.05). The number and distribution of adverse events were similar in both groups. Conclusion A fixed-dose combination of paracetamol, chlorphenamine and phenylephrine was safe and more effective than placebo in the symptomatic treatment of the common cold or flu-like syndrome in adults.

BACKGROUND Alzheimer's disease (AD) is the most common type of dementia. The objective of this paper is to propose a novel method to identify differential pathways in hippocampus AD. MATERIAL AND METHODS We proposed a combined method by merging existed methods. Firstly, pathways were identified by four known methods (DAVID, the neaGUI package, the pathway-based co-expressed method, and the pathway network approach), and differential pathways were evaluated through setting weight thresholds. Subsequently, we combined all pathways by a rank-based algorithm and called the method the combined method. Finally, common differential pathways across two or more of five methods were selected. RESULTS Pathways obtained from different methods were also different. The combined method obtained 1639 pathways and 596 differential pathways, which included all pathways gained from the four existing methods; hence, the novel method solved the problem of inconsistent results. Besides, a total of 13 common pathways were identified, such as metabolism, immune system, and cell cycle. CONCLUSIONS We have proposed a novel method by combining four existing methods based on a rank product algorithm, and identified 13 significant differential pathways based on it. These differential pathways might provide insight into treatment and diagnosis of hippocampus AD.

Background: Scarring airway stenosis is commonly seen in China as compared to other developed countries, due to the high prevalence of tuberculosis. Nowadays, interventional bronchoscopy treatment has been widely used to treat this disease in China. This study demonstrated the characteristics of scarring airway stenosis in Chinese adults and retrospectively evaluated the efficacy of interventional bronchoscopy treatment of this disease. Methods: Patients with scarring airway stenosis from 18 tertiary hospitals were enrolled between January 2013 and June 2016. The causes, site, and length of scarring airway stenosis were analyzed, and the efficacy of the interventional bronchoscopy treatment was evaluated. Results: The final study cohort consisted of 392 patients. Endotracheobronchial tuberculosis (EBTB) was the most common cause of scarring airway stenosis (305/392, 77.8%) in Chinese adults with a high rate of incidence in young women. The left main bronchus was most susceptible to EBTB, and most posttuberculosis airway scarring stenosis length was 1.1–2.0 cm. The average clinical success rate of interventional bronchoscopy treatment for scarring airway stenosis in Chinese patients is 60.5%. The stent was inserted in 8.7% scarring airway stenosis in China. Conclusions: Scarring airway stenosis exhibits specific characteristics in Chinese patients. Interventional bronchoscopy is a useful and safe treatment method for the disease. PMID:29363641

There are no definitive treatments of facial redness for rosacea. All treatments aim to alleviate symptoms. Patients' perspectives of two emerging modalities, Low level light therapy and laser treatments are not well characterized. The purpose is to further understand rosacea patients unmet needs about these modalities, Methods: The publicly accessible, online rosacea forum was accessed at august 2013. Stratified random sampling method has done to identify a 10% sample of total 27,051 posts. The Posts were published in the "Laser and IPL therapy" and "Low level light therapy" forums were qualitatively analyzed. Patients discussed a variety of topics, but most commonly discussed effectiveness (34.2%), treatment education (19.3%), and adverse effects (18%). Relationship with the health care provider (9.9%), cost (8.1%), execution of treatments (8.1%) and convenience of treatments (2.5%) were less commonly discussed, but contributed to patients' decisions about utilizing laser and light therapies. Online forums are utilized to fulfill patients' desire for educational, empathic and collaborative relationship. Patients' adherence to laser and light therapies will likely increase if costs are reduced, reduction in redness is consistent with their expectations, and if physicians empower them through education on device choices and managing adverse effects.

A crucial component of making individualized treatment decisions is to accurately predict each patient's disease risk. In clinical oncology, disease risks are often measured through time-to-event data, such as overall survival and progression/recurrence-free survival, and are often subject to censoring. Risk prediction models based on recursive partitioning methods are becoming increasingly popular largely due to their ability to handle nonlinear relationships, higher-order interactions, and/or high-dimensional covariates. The most popular recursive partitioning methods are versions of the Classification and Regression Tree (CART) algorithm, which builds a simple interpretable tree structured model. With the aim of increasing prediction accuracy, the random forest algorithm averages multiple CART trees, creating a flexible risk prediction model. Risk prediction models used in clinical oncology commonly use both traditional demographic and tumor pathological factors as well as high-dimensional genetic markers and treatment parameters from multimodality treatments. In this article, we describe the most commonly used extensions of the CART and random forest algorithms to right-censored outcomes. We focus on how they differ from the methods for noncensored outcomes, and how the different splitting rules and methods for cost-complexity pruning impact these algorithms. We demonstrate these algorithms by analyzing a randomized Phase III clinical trial of breast cancer. We also conduct Monte Carlo simulations to compare the prediction accuracy of survival forests with more commonly used regression models under various scenarios. These simulation studies aim to evaluate how sensitive the prediction accuracy is to the underlying model specifications, the choice of tuning parameters, and the degrees of missing covariates.

Acute auricular hematoma can be caused by direct blunt trauma or other injury to the external ear. It is typically seen in those who practice full contact sports such as boxing, wrestling, and rugby. "Cauliflower ear" deformity, fibrocartilage formation during scarring, is a common complication of auricular hematomas. Therefore, acute drainage of the hematoma and postprocedural techniques for preventing recurrence are necessary for preventing the deformity. There are many techniques although no superior method of treatment has been found. In this case report, we describe a novel method using needle aspiration followed by the application of a magnet and an adapted disc to the affected area of the auricular. This minimally invasive, simple, and accessible method could potentially facilitate the treatment of cauliflower ear among full contact sports athletes.
A cohort study of Chlamydia trachomatis treatment failure in women: a study protocol
2013-01-01
Background Chlamydia trachomatis is the most commonly diagnosed bacterial sexually transmitted infection in the developed world and diagnosis rates have increased dramatically over the last decade. Repeat infections of chlamydia are very common and may represent re-infection from an untreated partner or treatment failure. The aim of this cohort study is to estimate the proportion of women infected with chlamydia who experience treatment failure after treatment with 1 gram azithromycin. Methods/design This cohort study will follow women diagnosed with chlamydia for up to 56 days post treatment. Women will provide weekly genital specimens for further assay. The primary outcome is the proportion of women who are classified as having treatment failure 28, 42 or 56 days after recruitment. Comprehensive sexual behavior data collection and the detection of Y chromosome DNA and high discriminatory chlamydial genotyping will be used to differentiate between chlamydia re-infection and treatment failure. Azithromycin levels in high-vaginal specimens will be measured using a validated liquid chromatography – tandem mass spectrometry method to assess whether poor azithromycin absorption could be a cause of treatment failure. Chlamydia culture and minimal inhibitory concentrations will be performed to further characterize the chlamydia infections. Discussion Distinguishing between treatment failure and re-infection is important in order to refine treatment recommendations and focus infection control mechanisms. If a large proportion of repeat chlamydia infections are due to antibiotic treatment failure, then international recommendations on chlamydia treatment may need to be re-evaluated. If most are re-infections, then strategies to expedite partner treatment are necessary. PMID:23957327

Background Missing data are common in alcohol clinical trials for both continuous and binary endpoints. Approaches to handle missing data have been explored for continuous outcomes, yet no studies have compared missing data approaches for binary outcomes (e.g., abstinence, no heavy drinking days). The present study compares approaches to modeling binary outcomes with missing data in the COMBINE study. Method We included participants in the COMBINE Study who had complete drinking data during treatment and who were assigned to active medication or placebo conditions (N=1146). Using simulation methods, missing data were introduced under common scenarios with varying sample sizes and amounts of missing data. Logistic regression was used to estimate the effect of naltrexone (vs. placebo) in predicting any drinking and any heavy drinking outcomes at the end of treatment using four analytic approaches: complete case analysis (CCA), last observation carried forward (LOCF), the worst-case scenario of missing equals any drinking or heavy drinking (WCS), and multiple imputation (MI). In separate analyses, these approaches were compared when drinking data were manually deleted for those participants who discontinued treatment but continued to provide drinking data. Results WCS produced the greatest amount of bias in treatment effect estimates. MI usually yielded less biased estimates than WCS and CCA in the simulated data, and performed considerably better than LOCF when estimating treatment effects among individuals who discontinued treatment. Conclusions Missing data can introduce bias in treatment effect estimates in alcohol clinical trials. Researchers should utilize modern missing data methods, including MI, and avoid WCS and CCA when analyzing binary alcohol clinical trial outcomes. PMID:27254113

In survival analysis, treatment effects are commonly evaluated based on survival curves and hazard ratios as causal treatment effects. In observational studies, these estimates may be biased due to confounding factors. The inverse probability of treatment weighted (IPTW) method based on the propensity score is one of the approaches utilized to adjust for confounding factors between binary treatment groups. As a generalization of this methodology, we developed an exact formula for an IPTW log-rank test based on the generalized propensity score for survival data. This makes it possible to compare the group differences of IPTW Kaplan-Meier estimators of survival curves using an IPTW log-rank test for multi-valued treatments. As causal treatment effects, the hazard ratio can be estimated using the IPTW approach. If the treatments correspond to ordered levels of a treatment, the proposed method can be easily extended to the analysis of treatment effect patterns with contrast statistics. In this paper, the proposed method is illustrated with data from the Kyushu Lipid Intervention Study (KLIS), which investigated the primary preventive effects of pravastatin on coronary heart disease (CHD). The results of the proposed method suggested that pravastatin treatment reduces the risk of CHD and that compliance to pravastatin treatment is important for the prevention of CHD.

2018-02-01
Dental implants are common method to replace decayed or broken tooth. As the implant treatment procedures varies according to the patients' jawbone, bone ridge, and sinus structure, appropriate examinations are necessary for successful treatment. Currently, radiographic examinations including periapical radiology, panoramic X-ray, and computed tomography are commonly used for diagnosing and monitoring. However, these radiographic examinations have limitations in that patients and operators are exposed to radioactivity and multiple examinations are performed during the treatment. In this study, we demonstrated photoacoustic (PA) and ultrasound (US) combined imaging of dental implant that can lower the total amount of absorbed radiation dose in dental implant treatment. An acoustic resolution PA macroscopy and a clinical PA/US system was used for dental implant imaging. The acquired dual modal PA/US imaging results support that the proposed photoacoustic imaging strategy can reduce the radiation dose rate during dental implant treatment.
New technique for treating pseudocyst of the auricle.
Zhu, L X; Wang, X Y
1990-01-01
Although pseudocyst of the auricle is a common disease in China, its cause and mechanism are still not clear. Several methods of treatment have been advocated: repeated aspirations combined with physiotherapy, and incision and drainage with contour pressure dressing, magnetotherapy etc. In recent years, a new technique with a drainage tube inserted into the pseudocyst using a guide needle has been used in our hospital in the treatment of this condition. We report 45 cases treated by this method, none of whom had the condition previously.
Measuring survival time: a probability-based approach useful in healthcare decision-making.
2011-01-01
In some clinical situations, the choice between treatment options takes into account their impact on patient survival time. Due to practical constraints (such as loss to follow-up), survival time is usually estimated using a probability calculation based on data obtained in clinical studies or trials. The two techniques most commonly used to estimate survival times are the Kaplan-Meier method and the actuarial method. Despite their limitations, they provide useful information when choosing between treatment options.

We reviewed many of the essential Greek myths to identify the methods used at that time to relieve the pain of both illness and surgery, and we discovered many pioneering methods. Both gods and demigods implemented these methods to ease pain, to conduct surgery, and, on occasion, to kill mythological beings. The myths describe the three most common components of anesthesia: hypnosis, amnesia, and (an)algesia. Drugs and music-aided hypnosis were two of the most common methods use to treat emotional and surgical pain. This article identifies highlights in the development of concepts to treat pain in Greek mythology. The examples found in the Greek myths remind us of the historical significance of pain treatment.

Parasites are a common cause of dermatological disease in the dog and cat. Knowledge of different miticidal options for the common parasitic diseases is imperative when choosing the appropriate treatment for a patient. This is especially important with the recent advent of safer and more effective antiparasitic medications. Diagnostic and therapeutic methods for Cheyletiella spp., Demodex spp., Notoedres cati, Sarcoptes scabei, and Otodectes cyanotis are discussed, with emphasis on protocols for miticidal therapies, as well as safety concerns and side effects. This information will allow the practitioner to choose the safest and most efficient treatment for parasitic skin disease in their small animal patients.

Aim: Foreign bodies ingested by the oral route enter into the gastrointestinal tract and are considered a significant health problem in the childhood. In this study, we evaluated the pediatric patients who presented to our hospital with the complaint of ingestion of foreign body. Material and Methods: The hospital records of all children who presented to our clinic because of ingestion of foreign body between January 2008 and January 2015 were examined retrospectively. The complaints at admission, the types of foreign bodies ingested, the localization of the foreign body in the gastrointestinal tract and the approaches and treatment methods used were examined. Results: Thirty-six (56%) of 64 patients included in the study were male and 28 (44%) were female and the mean age was 5.7±4.6 years (10 months–17 years). Thirty eight (59%) of 64 children who were included in the assessment were below the age of five years. The most common complaint at presentation was parental recognition of the ingested object and dysphagia. The most commonly ingested foreign bodies included coins, sewing pins, safety pins and hairclips. Nail clipper detected in the stomach, sewing pin which penetrated through the duodenal wall and stuck to hepatic parenchyma were the first pediatric cases in the literature. Upper esophagus was the most common location for foreign bodies. Endoscopic examinations were performed in 55 of 64 children. Conclusions: Early detection and treatment of ingested foreign bodies in the upper gastrointestinal system is important in terms of preventing possible complications. In our study, the most frequent foreign bodies detected in the upper digestive tract were coins and they were most frequently detected in the upper esophagus. Most of our patients were below the age of five years. Flexible endoscopic method was used commonly for treatment. PMID:26884693
[ENDOSONOGRAPHY IN THE DIFFERENTIAL DIAGNOSIS OF THE COMMON BILE DUCT STENOSIS].

2015-01-01
The article states the results of examination and treatment of 57 patients with stenosis of the common bile duct of various genesis. The main aim of the work is criteria definition and evaluation of diagnostic significance of endosonography in the differential diagnosis of benign and malignant common bile duct stenosis. The paper presents a methodology of endoscopic ultrasound and basic criteria for the differential diagnosis of tumors and other lesions of the extrahepatic bile ducts. A comparative analysis of endosonography, ultrasound, CT, MRCP was conducted. The sensitivity of endosonography in determining the nature of the common bile duct stenosis was 97.7%, a specificity 100% and accuracy 98.2%, which is superior to other methods of radiological diagnosis. In comprehensive surgical centers endosonography should be used as a method of specifying the final diagnosis to determine the nature of the common bile duct stenosis, particularly at low constriction location.
Hydrogen Peroxide Enhances Removal of NOx from Flue Gases
NASA Technical Reports Server (NTRS)
Collins, Michelle M.
2005-01-01
Pilot scale experiments have demonstrated a method of reducing the amounts of oxides of nitrogen (NOx) emitted by industrial boilers and powerplant combustors that involves (1) injection of H2O2 into flue gases and (2) treatment of the flue gases by caustic wet scrubbing like that commonly used to remove SO2 from combustion flue gases. Heretofore, the method most commonly used for removing NOx from flue gases has been selective catalytic reduction (SCR), in which the costs of both installation and operation are very high. After further development, the present method may prove to be an economically attractive alternative to SCR.
Statistical primer: propensity score matching and its alternatives.

Propensity score (PS) methods offer certain advantages over more traditional regression methods to control for confounding by indication in observational studies. Although multivariable regression models adjust for confounders by modelling the relationship between covariates and outcome, the PS methods estimate the treatment effect by modelling the relationship between confounders and treatment assignment. Therefore, methods based on the PS are not limited by the number of events, and their use may be warranted when the number of confounders is large, or the number of outcomes is small. The PS is the probability for a subject to receive a treatment conditional on a set of baseline characteristics (confounders). The PS is commonly estimated using logistic regression, and it is used to match patients with similar distribution of confounders so that difference in outcomes gives unbiased estimate of treatment effect. This review summarizes basic concepts of the PS matching and provides guidance in implementing matching and other methods based on the PS, such as stratification, weighting and covariate adjustment.
Meta-Analysis of Rare Binary Adverse Event Data

2013-01-01
We examine the use of fixed-effects and random-effects moment-based meta-analytic methods for analysis of binary adverse event data. Special attention is paid to the case of rare adverse events which are commonly encountered in routine practice. We study estimation of model parameters and between-study heterogeneity. In addition, we examine traditional approaches to hypothesis testing of the average treatment effect and detection of the heterogeneity of treatment effect across studies. We derive three new methods, simple (unweighted) average treatment effect estimator, a new heterogeneity estimator, and a parametric bootstrapping test for heterogeneity. We then study the statistical properties of both the traditional and new methods via simulation. We find that in general, moment-based estimators of combined treatment effects and heterogeneity are biased and the degree of bias is proportional to the rarity of the event under study. The new methods eliminate much, but not all of this bias. The various estimators and hypothesis testing methods are then compared and contrasted using an example dataset on treatment of stable coronary artery disease. PMID:23734068

In a randomized controlled clinical trial that assesses treatment efficacy, a common objective is to assess the association of a measured biomarker response endpoint with the primary study endpoint in the active treatment group, using a case-cohort, case-control, or two-phase sampling design. Methods for power and sample size calculations for such biomarker association analyses typically do not account for the level of treatment efficacy, precluding interpretation of the biomarker association results in terms of biomarker effect modification of treatment efficacy, with detriment that the power calculations may tacitly and inadvertently assume that the treatment harms some study participants. We develop power and sample size methods accounting for this issue, and the methods also account for inter-individual variability of the biomarker that is not biologically relevant (e.g., due to technical measurement error). We focus on a binary study endpoint and on a biomarker subject to measurement error that is normally distributed or categorical with two or three levels. We illustrate the methods with preventive HIV vaccine efficacy trials, and include an R package implementing the methods. PMID:27037797

Missing cases following treatment are common in Web-based psychotherapy trials. Without the ability to directly measure and evaluate the outcomes for missing cases, the ability to measure and evaluate the effects of treatment is challenging. Although common, little is known about the characteristics of Web-based psychotherapy participants who present as missing cases, their likely clinical outcomes, or the suitability of different statistical assumptions that can characterize missing cases. Using a large sample of individuals who underwent Web-based psychotherapy for depressive symptoms (n=820), the aim of this study was to explore the characteristics of cases who present as missing cases at posttreatment (n=138), their likely treatment outcomes, and compare between statistical methods for replacing their missing data. First, common participant and treatment features were tested through binary logistic regression models, evaluating the ability to predict missing cases. Second, the same variables were screened for their ability to increase or impede the rate symptom change that was observed following treatment. Third, using recontacted cases at 3-month follow-up to proximally represent missing cases outcomes following treatment, various simulated replacement scores were compared and evaluated against observed clinical follow-up scores. Missing cases were dominantly predicted by lower treatment adherence and increased symptoms at pretreatment. Statistical methods that ignored these characteristics can overlook an important clinical phenomenon and consequently produce inaccurate replacement outcomes, with symptoms estimates that can swing from -32% to 70% from the observed outcomes of recontacted cases. In contrast, longitudinal statistical methods that adjusted their estimates for missing cases outcomes by treatment adherence rates and baseline symptoms scores resulted in minimal measurement bias (<8%). Certain variables can characterize and predict missing cases likelihood and jointly predict lesser clinical improvement. Under such circumstances, individuals with potentially worst off treatment outcomes can become concealed, and failure to adjust for this can lead to substantial clinical measurement bias. Together, this preliminary research suggests that missing cases in Web-based psychotherapeutic interventions may not occur as random events and can be systematically predicted. Critically, at the same time, missing cases may experience outcomes that are distinct and important for a complete understanding of the treatment effect. ©Eyal Karin, Blake F Dear, Gillian Z Heller, Monique F Crane, Nickolai Titov.

Selective serotonin reuptake inhibitor medications are one of the most common treatments for mood disorders. In humans, these medications are taken orally, usually once per day. Unfortunately, administration of antidepressant medications in rodent models is often through injection, oral gavage, or minipump implant, all relatively stressful procedures. The aim of the present study was to investigate how administration of the commonly used SSRI, fluoxetine, via a wafer cookie, compares to fluoxetine administration using an osmotic minipump, with regards to serum drug levels and hippocampal plasticity. For this experiment, adult female Sprague-Dawley rats were divided over the two administration methods: (1) cookie and (2) osmotic minipump and three fluoxetine treatment doses: 0, 5, or 10 mg/kg/day. Results show that a fluoxetine dose of 5 mg/kg/day, but not 10 mg/kg/day, results in comparable serum levels of fluoxetine and its active metabolite norfluoxetine between the two administration methods. Furthermore, minipump administration of fluoxetine resulted in higher levels of cell proliferation in the granule cell layer (GCL) at a 5 mg dose compared to a 10 mg dose. Synaptophysin expression in the GCL, but not CA3, was significantly lower after fluoxetine treatment, regardless of administration method. These data suggest that the administration method and dose of fluoxetine can differentially affect hippocampal plasticity in the adult female rat. PMID:24757568
[Physical therapy for idiopathic scoliosis].
Steffan, K
2015-11-01
The objective is the description and summary of the current state of idiopathic scoliosis treatment with physical therapy based on new scientific knowledge and concluded from more than 15 years of experience as a leading physician in two well-known clinics specializing in the conservative treatment of scoliosis. Based on current scientific publications on physical therapy in scoliosis treatment and resulting from the considerable personal experience gained working with conservative treatment and consulting scoliosis patients (as inpatients and outpatients), the current methods of physical therapy have been compared and evaluated. Physical therapy according to Schroth and Vojta therapy are at present the most common and effective methods in the physical treatment of idiopathic scoliosis. These methods can be applied during inpatient or outpatient treatment or intensified in the practice of specialized therapists. As there are only a few scientific studies on this subject, the author's findings are based mainly on his own experiences of the conservative treatment of idiopathic scoliosis. Athough these experiences are the results of over 15 years of working in the field of therapy, and the Schroth method in combination with corrective bracing presents highly promising results, it would nevertheless be desirable to conduct detailed scientific studies to verify the effectiveness of conservative treatment.

The behavior of veterinary antibiotics in the soil is commonly studied using the following methods to add antibiotics to the soil: (A) adding manure collected from animals fed a diet that includes antibiotics; (B) adding antibiotic-free animal manure spiked with antibiotics; and (C) the direct addition of antibiotics. However, most studies have only used methods (B) and (C) in their research, and few studies have simultaneously compared the different antibiotic addition methods. This study used tylosin A (TYLA) as a model antibiotic to compare the effects of these three commonly used antibiotic addition methods on the dissipation rates of TYLA and the numbers of resistance genes in laboratory incubation experiments. The results showed that the three treatment methods produced similar TYLA degradation trends; however, there were significant differences (P<0.05) in the TYLA degradation half-life (t1/2) among the three methods. The half-life of TYLA degradation in treatments A, B and C was 2.44 ± 0.04, 1.21 ± 0.03 and 5.13 ± 0.11 days, respectively. The presence of manure resulted in a higher electrical conductivity (EC), higher relative abundance of Citrobacter amalonaticus, higher macrolide resistant gene (ermB, ermF and ermT) count and lower ecological toxicity in the soil, which could partially explain the higher TYLA degradation rate in the treatments containing manure. The higher degradation rate of TYLA in treatment B when compared to treatment A could be due to the lower concentrations of tylosin B (TYLB) and tylosin D (TYLD). The main route for veterinary antibiotics to enter the soil is via the manure of animals that have been administered antibiotics. Therefore, the more appropriate method to study the degradation and ecotoxicity of antibiotic residues in the soil is by using manure from animals fed/administered the particular antibiotic rather than by adding the antibiotic directly to the soil.

Magnetic resonance (MR) examinations of men with prostate cancer are most commonly performed for detecting, characterizing, and staging the extent of disease to best determine diagnostic or treatment strategies, which range from biopsy guidance to active surveillance to radical prostatectomy. Given both the exam's importance to individual treatment plans and the time constraints present for its operation at most institutions, it is essential to perform the study effectively and efficiently. This article reviews the most commonly employed modern techniques for prostate cancer MR examinations, exploring the relevant signal characteristics from the different methods discussed and relating them to intrinsic prostate tissue properties. Also, a review of recent articles using these methods to enhance clinical interpretation and assess clinical performance is provided. PMID:23606141

Hemopneumothorax is a common sequelae of traumatic thoracic injury. The most effective treatment of this condition is thoracic drainage. Despite the common occurrence of this condition, available instruments are difficult to use emergently, particularly when large amounts of patients need to be drained. In the present experiment, a newly designed chest tube and thoracic closed drainage package is described and preliminarily evaluated with the goal to improve the treatment of traumatic hemopneumothorax. Twenty canines were divided into two groups. In one group, the newly designed thoracic closed drainage package was used, whereas in the other group a currently available chest tube and bottle were used. Drainage test, ultrasound examination, flushing test, and tension test were performed to evaluate the effectiveness of the drainage package. We found that the newly-designed drainage tube is as effective as the common tube when evaluated using all of the chosen methods. In addition, the package is very lightweight and portable. The newly-designed thoracic drainage package is very effective in the emergency treatment of thoracic trauma and may be more suitable for the emergency treatment of hemopneumothorax.
Treatments for the challenging behaviours of adults with intellectual disabilities.
Matson, Johnny L; Neal, Daniene; Kozlowski, Alison M
2012-10-01
To provide an overview and critical assessment of common problems and best evidence practice in treatments for the challenging behaviours (CBs) of adults with intellectual disabilities (IDs). Commonly observed problems that present obstacles to successful treatment plans are discussed, followed by an analysis of available research on the efficacy of behavioural and pharmacological therapies. Behavioural and pharmacological interventions are most commonly used when addressing CBs in people with IDs. However, within each of these techniques, there are methods that have support in the literature for efficacy and those that do not. As clinicians, it is important to follow research so that we are engaging in best practices when developing treatment plans for CBs. One of the most consuming issues for psychiatrists and other mental health professionals who work with people who evince developmental disabilities, such as IDs, are CBs. These problems are very dangerous and are a major impediment to independent, less restrictive living. However, there is a major gap between what researchers show is effective and much of what occurs in real-world settings.

Antibiotic misuse for upper respiratory tract infections such as the common cold is widespread in clinical practice. Excessive prescription of antibiotics by doctors has resulted in increased antimicrobial resistance. This led to our objective of determining the percentage of doctors in Pakistan prescribing antibiotics for the treatment of common cold and to know about their knowledge in preventing the spread of this disease. It was a cross-sectional descriptive study, conducted in 9 cities of Pakistan including Rawalpindi, Islamabad, Peshawar, Lahore, Karachi, Faisalabad, Sargodha, Multan and D.G. Khan over a period of 03 months -from October to December, 2013. Questionnaire regarding the disease spread and its treatment was distributed among 300 randomly selected doctors in nine cities of Pakistan from both public and private sector. Eighteen percent of the doctors prescribe antibiotics for common cold. Only 113 (37.7%) doctors correctly responded that mean incubation period for common cold was 1-2 days. Two hundred and nine (69.7%) answered correctly that cold weather increases susceptibility to common cold. Only 84 (28%) responded correctly by choosing that regular and frequent hand-washing with good quality soaps was the most effective way to prevent spread of this disease in day-to-day life. Antibiotics are being prescribed for treatment of common cold by a large proportion of doctors. There is insufficient knowledge among our doctors regarding the factors which aggravate or alleviate common cold symptoms as well as the methods by which these infections can be prevented.
Rosacea Patient Perspectives on Homeopathic and Over-the-counter Therapies
Lan, Lucy; Kuo, Sandy; Huang, Karen E.; Taylor, Sarah L.; Feldman, Steven R.
2015-01-01
Background: Rosacea patients commonly employ nonprescription therapies. The authors’ aim was to understand rosacea patients’ perceptions of over-the-counter products, complementary and alternative medicine, and homeopathic therapies. Method: A public, online discussion forum comprising 3,350 members and 27,051 posts provided a source of 346 posts on patient perceptions on alternative rosacea treatments. Results: Three major themes of nonprescription treatment were identified—motivation for use, patient-provider discussions, and experience with these treatments. Perceived medication failure, barriers to treatment, and distrust of physicians drive patients to seek nonprescription therapies. Still, patients prefer to consult a physician on incorporating nonprescription therapies into treatment. Complementary and alternative medicine natural products (19.4% of posts), complementary and alternative medicine practices (16.5%), and homeopathic medicine (3.8%) were commonly discussed. Conclusion: Physicians have an opportunity to be a trusted source of information on the strengths and weaknesses of skin care products and other complementary treatments for rosacea. PMID:26557217

Bezoars are concretions of foreign bodies found in the gastrointestinal tract. In the past, most common method for the treatment of bezoar was surgical management. However, the current treatment methods include chemical dissolution and endoscopic mechanical lithotripsy. There were few reports on the treatment of phytobezoars by nasogastric Cola lavage. However, there was no report succeeded by oral route alone. In our two cases, phytobezoars were treated by oral administration of Coca-Cola. Our patients drank 700-800 mL of Coca-Cola daily, and after two months, complete dissolutions of bezoars were achieved. We report two cases of phytobezoars completely treated by drinking Coca-Cola.

Common Orbital Infections ~ State of the Art ~ Part I
Hamed-Azzam, Shirin; AlHashash, Islam; Briscoe, Daniel; Rose, Geoffrey E; Verity, David H.
2018-01-01
Infections of the orbit and periorbita are relatively frequent, and can cause significant local and systemic morbidity. Loss of vision occurs in more than 10% of patients, and systemic sequelae can include meningitis, intracranial abscess, and death. Numerous organisms infect the orbit, but the most common are bacteria. There are many methods through which orbital infections occur, with infection from the neighboring ethmoid sinuses the most likely cause for all age groups. Prompt management is essential in suspected orbital cellulitis, and involves urgent intravenous antibiotics, rehydration, and treatment of any co-existent underlying systemic disease, e.g., diabetes, renal failure. This review summarizes the common infectious processes of the orbit in both pediatric and adult groups. We review pathophysiology, symptoms, signs, and treatment for infectious orbital processes.

Effect of Surface Treatment on the Properties of Wool Fabric
NASA Astrophysics Data System (ADS)
Kan, C. W.; Yuen, C. W. M.; Chan, C. K.; Lau, M. P.
Wool fiber is commonly used in textile industry, however, it has some technical problems which affect the quality and performance of the finished products such as felting shrinkage, handle, lustre, pilling, and dyeability. These problems may be attributed mainly in the presence of wool scales on the fiber surface. Recently, chemical treatments such as oxidation and reduction are the commonly used descaling methods in the industry. However, as a result of the pollution caused by various chemical treatments, physical treatment such as low temperature plasma (LTP) treatment has been introduced recently because it is similarly capable of achieving a comparable descaling effect. Most of the discussions on the applications of LTP treatment on wool fiber were focused on applying this technique for improving the surface wettability and shrink resistance. Meanwhile, little discussion has been made on the mechanical properties, thermal properties, and the air permeability. In this paper, wool fabric was treated with LTP treatment with the use of a non-polymerizing gas, namely oxygen. After the LTP treatment, the fabrics low-stress mechanical properties, air permeability, and thermal properties were evaluated and discussed.

Many reports of treatments for suicidal patients claim effectiveness in reducing suicidal behavior but fail to demonstrate which treatment interventions, or combinations thereof, diminish suicidality. In this study, treatment manuals for empirically supported psychological treatments for suicidal patients were examined to identify which interventions they had in common and which interventions were treatment-specific. Empirically supported treatments for suicidality were identified through a literature search of PsychLit and MEDLINE for the years 1970-2007, employing the following search strategy: [suicide OR parasuicide] AND [therapy OR psychotherapy OR treatment] AND [random OR randomized]. After identifying the reports on randomized controlled studies that tested effectiveness of different treatments, the reference list of each report was searched for further studies. Only reports published in English were included. To ensure that rated manuals actually correspond to the delivered and tested treatments, we included only treatment interventions with explicit adherence rating and scoring and with adequate adherence ratings in the published studies. Five manualized treatments demonstrating efficacy in reducing suicide risk were identified and were independently evaluated by raters using a list of treatment interventions. The common interventions included a clear treatment framework; a defined strategy for managing suicide crises; close attention to affect; an active, participatory therapist style; and use of exploratory and change-oriented interventions. Some treatments encouraged a multimodal approach and identification of suicidality as an explicit target behavior, and some concentrated on the patient-therapist relationship. Emphasis on interpretation and supportive interventions varied. Not all methods encouraged systematic support for therapists. This study identified candidate interventions for possible effectiveness in reducing suicidality. These interventions seem to address central characteristics of suicidal patients. Further studies are needed to confirm which interventions and which combinations thereof are most effective. 2010 Physicians Postgraduate Press, Inc.

Acute auricular hematoma can be caused by direct blunt trauma or other injury to the external ear. It is typically seen in those who practice full contact sports such as boxing, wrestling, and rugby. “Cauliflower ear” deformity, fibrocartilage formation during scarring, is a common complication of auricular hematomas. Therefore, acute drainage of the hematoma and postprocedural techniques for preventing recurrence are necessary for preventing the deformity. There are many techniques although no superior method of treatment has been found. In this case report, we describe a novel method using needle aspiration followed by the application of a magnet and an adapted disc to the affected area of the auricular. This minimally invasive, simple, and accessible method could potentially facilitate the treatment of cauliflower ear among full contact sports athletes. PMID:29403318

Background: Persistent nipple pain is one of the most common reasons given by mothers for ceasing exclusive breastfeeding. We aimed to determine the frequency of nipple pain as a reason for consultation, the most common attributed aetiologies, and the effectiveness of the advice and treatment given. Methods: All consultations at the Breast Feeding Centre of Western Australia (WA) were audited over two six-month periods in 2011 (n = 469) and 2014 (n = 708). Attributed cause(s) of nipple pain, microbiology results, treatment(s) advised, and resolution of pain were recorded. Results: Nipple pain was one of the reasons for consultation in 36% of cases. The most common attributed cause of nipple pain was incorrect positioning and attachment, followed by tongue tie, infection, palatal anomaly, flat or inverted nipples, mastitis, and vasospasm. Advice included correction of positioning and attachment, use of a nipple shield, resting the nipples and expressing breastmilk, frenotomy, oral antibiotics, topical treatments, and cold or warm compresses. Pain was resolving or resolved in 57% of cases after 18 days (range 2–110). Conclusion: The multiple attributed causes of nipple pain, possibly as a result of a cascade of events, suggests that effective early lactation management for prevention of nipple pain and early diagnosis and effective treatment are crucial to avoid early weaning.

Purpose: To report our experience in the use of percutaneous extraction of common bile duct stones detected in the post-cholecystectomy period. Methods: Forty-two patients in whom endoscopic cannulation and/or sphincterotomy had failed or could not be done due to several reasons underwent balloon dilatation of the ampulla of Vater and subsequent advancement of the stones via the percutaneous transhepatic route or T-tube tract. Results: The procedure was successful in 42 cases. In three patients, stones were crushed in the common bile duct and pushed as fragments into the duodenum. In all cases transient adverse effects were observed. There were nomore » major complications. All cases were checked with ultrasonography for 6 months after the procedure. Conclusion: Percutaneous extraction of common bile duct stones is an effective method of treatment with a high success rate,low complication rate and shorter hospital stay. It may serve as an alternative method in cases where endoscopic removal of stones fails.« less

Background Hypertension, notably untreated or uncontrolled, is a major risk factor for cardiovascular diseases (CVD) morbidity and mortality. In countries in transition, little is known about the epidemiology of hypertension, and its biochemical correlates. This study was carried out in Al Ain, United Arab Emirates, to characterize self-reported (SR) normotensives and hypertensives in terms of actual hypertension status, demographic variables, CVD risk factors, treatment, and sequalae. Methods A sample, stratified by SR hypertensive status, of 349 SR hypertensives (Mean age ± SD; 50.8 ± 9.2 yrs; Male: 226) and 640 SR normotensives (42.9 ± 9.3 yrs, Male: 444) among nationals and expatriates was used. Hypertensives and normotensive subjects were recruited from various outpatient clinics and government organizations in Al-Ain city, United Arab Emirates (UAE) respectively. Anthropometric and demographic variables were measured by conventional methods. Results Both under-diagnosis of hypertension (33%) and under-treatment (76%) were common. Characteristics of undiagnosed hypertensives were intermediate between normotensives and SR hypertensives. Under-diagnosis of hypertension was more common among foreigners than among nationals. Risk factors for CVD were more prevalent among SR hypertensives. Obesity, lack of exercise and smoking were found as major risk factors for CVD among hypertensives in this population. Conclusion Hypertension, even severe, is commonly under-diagnosed and under-treated in the UAE. Preventive strategies, better diagnosis and proper treatment compliance should be emphasized to reduce incidence of CVD in this population. PMID:16753071

Unconsummated marriage is a problem among couples who would not be able to perform natural sexual intercourse and vaginal penetration. This disorder is more common in developing countries and sometimes couples would come up with non-technical and non-scientific methods to overcome their problem. Multi-dimensional approach and narrative exposure therapy used in this case. This study would report a case of unconsummated marriage between a couple after 6 years. The main problem of this couple was vaginismus and post-traumatic stress. Treatment with multi-dimensional approach for this couple included methods like narrative exposure therapy, educating the anatomy of female and male reproductive system, correcting misconceptions, educating foreplay, educating body exploring and non-sexual and sexual massage and penetrating the vagina first by women finger and then men's after relaxation. The entire stages of the treatment lasted for four sessions and at the one-month follow-up couple's satisfaction was desirable. Unconsummated marriage is one of the main sexual problems; it is more common in developing countries than developed countries and cultural factors are effective on intensifying this disorder. The use of multi-dimensional approach in this study led to expedite diagnosis and treatment of vaginismus.

This report is the SOSORT Consensus Paper on Terminology for use in the treatment of conservative spinal deformities. Figures are provided and relevant literature is cited where appropriate. The Delphi method was used to reach a preliminary consensus before the meeting, where the terms that still needed further clarification were discussed. A final agreement was found for all the terms, which now constitute the base of this glossary. New terms will be added after being discussed and accepted. When only one set of terms is used for communication in a place or among a group of people, then everyone can clearly and efficiently communicate. This principle applies for any professional group. Until now, no common set of terms was available in the field of the conservative treatment of scoliosis and spinal deformities. This glossary gives a common base language to draw from to discuss data, findings and treatment.

Background: An opportunity to address the needs of patients with common mental disorders (CMDs) resides in primary care. Barriers are restricting availability of treatment for CMDs in primary care. By understanding the incentives that promote and the disincentives that deter treatment for CMDs in a collaborative primary care context, this study aims to help contribute to goals of greater access to mental healthcare. Method: A qualitative pilot study using semi-structured interviews with thematic analysis. Results: Participants identified 10 themes of incentives and disincentives influencing quality treatment of CMDs in a collaborative primary care setting: high service demands, clinical presentation, patient-centred care, patient attributes, education, physician attributes, organizational, access to mental health resources, psychiatry and physician payment model. Conclusion: An understanding of the incentives and disincentives influencing care is essential to achieve greater integration and capacity for care for the treatment of CMDs in primary care.

Although quantitative designs are commonly used in clinical research, some studies require qualitative methods. These designs are different from quantitative methods; thus, researchers should be aware of data collection methods and analyses for qualitative research. Qualitative methods are particularly useful to understand patient experiences with the treatment or new methods of management or to explore issues in detail. These methods are useful in social and behavioral research. In qualitative research, often, the main focus is to understand the issue in detail rather than generalizability; thus, the sampling methods commonly used are purposive sampling; quota sampling; and snowball sampling (for hard to reach groups). Data can be collected using in-depth interviews (IDIs) or focus group discussions (FGDs). IDI is a one-to-one interview with the participant. FGD is a method of group interview or discussion, in which more than one participant is interviewed at the same time and is usually led by a facilitator. The commonly used methods for data analysis are: thematic analysis; grounded theory analysis; and framework analysis. Qualitative data collection and analysis require special expertise. Hence, if the reader plans to conduct qualitative research, they should team up with a qualitative researcher. PMID:28794545

Intestinal stoma creation is one of the most common surgical procedures. The most common long-term complication following stoma creation is parastomal hernia, which according to some authors is practically unavoidable. Statistical differences of its occurrence are mainly due to patient observation time and evaluation criteria. Consequently, primary prevention methods such as placement of prosthetic mesh and newly developed minimally invasive methods of stoma creation are used. It seems that in the light of evidence-based medicine, the best way to treat parastomal hernia is the one that the surgeon undertaking therapy is the most experienced in and is suited to the individuality of each patient, his condition and comorbidities. As a general rule, reinforcing the abdominal wall with a prosthetic mesh is the treatment of choice, with a low rate of complications and relapses over a long period of time. The current trend is to use lightweight, large pore meshes. PMID:29643952

Font, Xavier; Artola, Adriana; Sánchez, Antoni
2011-01-01
Environmental policies at the European and global level support the diversion of wastes from landfills for their treatment in different facilities. Organic waste is mainly treated or valorized through composting, anaerobic digestion or a combination of both treatments. Thus, there are an increasing number of waste treatment plants using this type of biological treatment. During waste handling and biological decomposition steps a number of gaseous compounds are generated or removed from the organic matrix and emitted. Different families of Volatile Organic Compounds (VOC) can be found in these emissions. Many of these compounds are also sources of odor nuisance. In fact, odors are the main source of complaints and social impacts of any waste treatment plant. This work presents a summary of the main types of VOC emitted in organic waste treatment facilities and the methods used to detect and quantify these compounds, together with the treatment methods applied to gaseous emissions commonly used in composting and anaerobic digestion facilities.

2017-01-01
Enterocutaneous fistulas occur most commonly following surgery. A minority of them is caused by a myriad of other etiologies including infection, malignancy, and radiation. While some fistulas may close spontaneously, most patients will eventually need surgery to resolve this pathology. Successful treatment entails adoption of various methods of treatment aimed at control of sepsis, protection of surrounding skin and soft tissue, control of fistula output, and maintenance of nutrition, with eventual spontaneous or surgical closure of the fistula. The aim of this article is to review the various treatment options in their appropriate context. PMID:28825016

Ma, Chunhua; Jiang, Rong
2012-05-01
Brain metastases is one of the most common complications of non-small cell lung cancer, whole brain radiotherapy (WBRT), stereotactic radiosurgery (SRS), surgery and chemotherapy are standard methods in the treatment of brain metastases. But the effect of those treatments are still sad. Comprehensive treatment can prolong the survival and improve the quality of life. Recently, the improvement of technology, targeted therapy, survival time and the quality of life are in increasingly concerned. The paper make a summary of current situation and progress for comprehensive therapy of brain metastases.
Oak regeneration potential increased by shelterwood treatments

In much of the Central Hardwood Forest Region, oak species are not regenerating well, even though large oak trees are common within the existing forests. The shelterwood method has been suggested as a potential tool for establishing and developing advanced regeneration where it is lacking. The 10-yr results from a study of several variants of the shelterwood method...

Idiopathic clubfoot is one of the most common problems in paediatric orthopaedics. The treatment is controversial and continues to be one of the challenges in paediatric orthopaedics. The aim of this review is to assess the different methods of clubfoot treatment used over the years in light of the documentation present in the literature and art paintings from the antiquity to the end of the 19th century. The aim of this paper is to review all treatment methods of the clubfoot over the years that were proposed to provide patients a functional, pain-free, normal-looking foot, with good mobility, without calluses, and requiring no special shoes. Hippocrates was the first to write references about treatment methods of clubfoot. After the Middle Ages and the Renaissance where patients were treated by barber-surgeons, quacks and charlatans, bonesetters, and trussmakers, there were more detailed studies on the disease, with the help of famous names in medicine such as Venel and Scarpa.
Data Driven Approach to Burden of Treatment Measurement: A Study of Patients with Breast Cancer
Cheng, Alex C.; Levy, Mia A.
2016-01-01
Chronic disease affects patient quality of life through symptoms of the disease and the work of receiving treatment. While the effects of illness are well investigated, the burden of treatment is not commonly studied or monitored. We developed a method to quantify one dimension of the burden of treatment based on patient encounters with the healthcare system. We applied this method to a population of stage I-III breast cancer patients. As hypothesized and observed, stage IIIpatients had more appointments, spent more time in clinic, and spent more time admitted to the hospital in the first 18 months after diagnosis compared to stage I and II patients. Future work will evaluate the reproducibility and generalizability of this method for quantifying burden of treatment across other clinical settings and chronic diseases. This approach could enable identification of high-risk groups that could benefit from interventions to decrease patient work and improve outcomes. PMID:28269934

Urinary tract infections (UTI) are one of the common chronic and recurrent bacterial infections. Uropathogens which are able to form biofilm constitute a major etiological factor in UTI, especially among elder patients who are subject to long-term catheterization. It is caused by the capacity of the microorganisms for efficient and permanent colonization of tissues and also adhesion to diverse polymers used for urological catheter production such as propylene, polystyrene, silicone, polyvinyl chloride or silicone coated latex. Antibiotic therapy is the most common treatment for UTI. Fluoroquinolones, nitrofurans, beta-lactams, aminoglycosides, trimethoprim and sulfonamides are used predominantly. However, the biofilm due to its complex structure constitutes an effective barrier to the antibiotics used in the treatment of urinary tract infections. In addition, the growing number of multidrug resistant strains limits the usage of many of the currently available chemotherapeutic agents. Therefore, it seems important to search for new methods of treatment such as coating of catheters with non-pathogenic E. coli strains, the design of vaccines against fimbrial adhesive proteins of the bacterial cells or the use of bacteriophages.
Application of enzymes in the production of RTD black tea beverages: a review.
Kumar, Chandini S; Subramanian, R; Rao, L Jaganmohan
2013-01-01
Ready-to-drink (RTD) tea is a popular beverage in many countries. Instability due to development of haze and formation of tea cream is the common problem faced in the production of RTD black tea beverages. Thus decreaming is an important step in the process to meet the cold stability requirements of the product. Enzymatic decreaming approaches overcome some of the disadvantages associated with other conventional decreaming methods such as cold water extraction, chill decreaming, chemical stabilization, and chemical solubilization. Enzyme treatments have been attempted at three stages of black tea processing, namely, enzymatic treatment to green tea and conversion to black tea, enzymatic treatment to black tea followed by extraction, and enzymatic clarification of extract. Tannase is the most commonly employed enzyme (tannin acyl hydrolase EC 3.1.1.20) aiming at improving cold water extractability/solubility and decreasing tea cream formation as well as improving the clarity. The major enzymatic methods proposed for processing black tea having a direct or indirect bearing on RTD tea production, have been discussed along with their relative advantages and limitations.
The Effectiveness of Low-Dye Taping in Reducing Pain Associated With Plantar Fasciitis.
Verbruggen, Laura A; Thompson, Melissa M; Durall, Chris J
2018-01-01
Plantar fasciitis is one of the most common musculoskeletal disorders of the foot. Initial treatment of plantar fasciitis is typically conservative and may include heel padding, steroid injections, night splinting, calf stretching, ultrasound, foot orthoses, and taping. However, while custom foot orthoses are a common treatment method for plantar fasciitis, there is often a waiting period of a few weeks for them to be manufactured and delivered. Therefore, taping of the foot is often used as a temporary treatment to alleviate pain during the initial waiting period. Furthermore, taping may also be used as an alternative to foot orthoses for patients who may not tolerate the plantar pressures of an orthotic or for tight-fitting footwear that may not accommodate insoles. Specifically, the low-Dye taping (LDT) technique is one of the most frequently used methods, and recent literature has suggested that it may improve pain outcomes. Therefore, this critically appraised topic was conducted to determine the extent to which current evidence supports the use of LDT to reduce pain in patients with plantar fasciitis.

Microcystins are the most commonly encountered water-borne cyanotoxins which present short- and long-term risks to human health. Guidelines at international and national level, and legislation in some countries, have been introduced for the effective health risk management of these potent hepatotoxic, tumour-promoters. The stable cyclic structure of microcystins and their common production by cyanobacteria in waterbodies at times of high total dissolved organic carbon content presents challenges to drinking water treatment facilities, with conventional, advanced and novel strategies under evaluation. Here, we have studied the removal of microcystins using three different forms of pumice particles (PPs), which are embedded into macroporous cryogel columns. Macroporous composite cryogel columns (MCCs) are a new generation of separation media designed to face this challenging task. Three different MCCs were prepared by adding plain PPs, Cu(2+)-attached PPs and Fe(3+)-attached PPs to reaction media before the cryogelation step. Column studies showed that MCCs could be successfully used as an alternative water treatment method for successful microcystin removal. Copyright © 2016 Elsevier Ltd. All rights reserved.

Objective To examine the treatment of obsessive compulsive disorder (OCD) in office-based physician practices. Methods Data from the 2003–2010 National Ambulatory Medical Care Survey, a nationally representative survey of visits to office-based physicians in the United States, were used to examine treatment of adult outpatient visits with a diagnosis of OCD. Results Most visits with a diagnosis of OCD (N=316) had been seen previously by the same physician (96%), usually a psychiatrist (86%), ≥6 times (56%) within the previous year. Most visits included psychotropic medications (84%), most commonly a serotonin reuptake inhibitor (69%) and less commonly included any psychotherapy (39%). Conclusions OCD is predominantly treated by psychiatrists using SRI medications, despite the prevalence of OCD and SRI prescribing practices in primary care. Given the potential shift in OCD treatment practice patterns after health care reform, future research on the treatment of OCD in primary care are warranted. PMID:24585056

Congenital talipes equinovarus may be the most common congenital orthopedic condition requiring treatment. Nonoperative treatment including different methods is generally accepted as the first step in the deformity correction. Ignacio Ponseti introduced his nonsurgical approach to the treatment of clubfoot in the early 1940s. The method is reportedly successful in treating clubfoot in patients up to 9 years of age. However, whether age at the beginning of treatment affects the rate of effective correction and relapse is unknown. We have applied the Ponseti method successfully with some modifications for 11 patients with a mean age of 11.2 years (range, 6 to 19 years) with neglected and untreated clubbed feet. The mean follow-up was 15 months (12 to 36 months). Correction was achieved with a mean of nine casts (six to 13). Clinically, 17 out of 18 feet (94.4%) were considered to achieve a good result with no need for further surgery. The application of this method of treatment is very simple and also cheap in developing countries with limited financial and social resources for health service. To the best of the authors' knowledge, such a modified method as a correction method for clubfoot in older children and adolescents has not been applied previously for neglected clubfeet in older children in the literature.

Objective To characterize population-level surgical treatment patterns for cervical carcinoma in situ (CIS) reported to the Michigan Cancer Surveillance Program (MCSP), and to inform data collection strategies. Methods All cases of cervical carcinoma in situ (CIS) (including cervical intraepithelial neoplasia grade 3 and adenocarcinoma in situ [AIS]) reported to the MCSP during 1998–2003 were identified. First course of treatment (ablative procedure, cone biopsy, loop electrosurgical excisional procedure [LEEP], hysterectomy, unspecified surgical treatment, no surgical treatment, unknown if surgically treated) was described by histology, race, and age at diagnosis. Results Of 17,022 cases of cervical CIS, 82.8% were squamous CIS, 3% AIS/adenosquamous CIS, and 14.2% unspecified/other CIS. Over half (54.7%) of cases were diagnosed in women under age 30. Excisional treatments (LEEP, 32.3% and cone biopsy, 17.3%) were most common, though substantial proportions had no reported treatment (17.8%) or unknown treatment (21.1%). Less common were hysterectomy (7.2%) and ablative procedures (2.6%). LEEP was the most common treatment for squamous cases, while hysterectomy was the most treatment for AIS/adenosquamous CIS cases. Across histologic types, a sizeable proportion of women diagnosed ≤30 years of age underwent excision, either LEEP (20%–38.7%) or cone biopsy (13.7%–44%). Conclusion Despite evidence suggesting it may be safer and equally effective as excision, ablation was rarely used for treating cervical squamous CIS. These population-based data indicate some notable differences in treatment by histology and age at diagnosis, with observed patterns appearing consistent with consensus guidelines in place at the time of study, but favoring more aggressive procedures. Future data collection strategies may need to validate treatment information, including the large proportion of no or unknown treatment. PMID:24002133

Methods and apparatuses for treating a surface of a work piece are described. In one implementation, a laser delivery subsystem is configured to direct a laser beam toward a treatment zone on a work surface. A cryogenic material delivery subsystem is operably coupled with the laser delivery subsystem and is configured to direct a stream comprising cryogenic material toward the treatment zone. Both the laser beam and stream cooperate to treat material of the work surface within the treatment zone. In one aspect, a nozzle assembly provides the laser beam and stream of cryogenic material along a common flow axis. In another aspect, the laser beam and stream are provided along different axes.

Introduction: The aim of this study was to gather information on the materials and methods employed in root canal treatment (RCT) by general dental practitioners (GDPs) in Iran. Methods and Materials: A questionnaire was distributed among 450 dentists who attended the 53th Iranian Dental Association congress. Participants were asked to consider demographic variables and answer the questions regarding the materials and methods commonly used in RCT. Descriptive statistics were given as absolute frequencies and valid percentages. The chi-square test was used to investigate the influence of gender and the years of professional activity for the employed materials and techniques. Results: The response rate was 84.88%. The results showed that 61.5% of the participants did not perform pulp sensitivity tests prior to RCT. Less than half of the general dental practitioners (47.4%) said that they would trace a sinus tract before starting the treatment. Nearly 16% of practitioners preferred the rubber dam isolation method. Over 36% of the practitioners reported using formocresol for pulpotomy. The combined approach of working length (WL) radiographs and electronic apex locators was used by 35.2% of the practitioners. Most of the respondents used K-file hand instruments for canal preparation and the technique of choice was step-back (43.5%), while 40.1% of respondents used NiTi rotary files, mostly ProTaper and RaCe. The most widely used irrigant was normal saline (61.8%). Calcium hydroxide was the most commonly used inter appointment medicament (84.6%). The most popular obturation technique was cold lateral condensation (81.7%) with 51% using zinc oxide-eugenol-based sealers. Conclusions: The majority of Iranian GDPs who participated in the present survey do not comply with quality guidelines of endodontic treatment. PMID:25834595

Synopsis Upper extremity tennis injuries are most commonly characterized as overuse injuries to the wrist, elbow and shoulder. The complex anatomy of these structures and their interaction with biomechanical properties of tennis strokes contributes to the diagnostic challenges. A thorough understanding of tennis kinetics, in combination with the current literature surrounding diagnostic and treatment methods, will improve clinical decision-making. PMID:27886833

Background Non-steroidal anti-inflammatory drugs (NSAIDs) are an effective and common treatment for chronic pain disorders, but long-term use is associated with risk of potentially life-threatening gastrointestinal adverse events (AEs). The proton pump inhibitor esomeprazole has been found to be effective for gastroprotection in NSAID users, but few long-term studies have been conducted in Japan. Methods This was an open-label, multicentre, single-arm, prospective 1-year study of treatment with esomeprazole (20 mg once daily) in Japanese patients (aged ≥20 years) with endoscopic evidence of previous peptic ulcer and receiving daily oral NSAID therapy (at a stable dose) for a chronic condition. Eligibility was not dictated by type of oral NSAID. The primary objective was to determine long-term safety and tolerability of esomeprazole. Efficacy for prevention of peptic ulcers was also determined (Kaplan-Meier method). All statistical analyses were descriptive. Results A total of 130 patients (73.1% women, mean age 62.1 years, 43.8% Helicobacter pylori-positive) received treatment with esomeprazole in addition to long-term NSAID therapy (most commonly for rheumatoid arthritis [n=42] and osteoarthritis [n=34]). Loxoprofen, meloxicam and diclofenac were the most commonly used NSAIDs; cyclo-oxygenase (COX)-2 selective agents were used by 16.2% of patients (n=21). Long-term compliance with esomeprazole (capsule counts) was >75% for the majority of patients. Although 16.9% of patients (n=22) experienced AEs judged to be possibly related to treatment with esomeprazole, they were mostly mild and transient. The most commonly reported possibly treatment-related AEs were abnormal hepatic function, headache, increased γ-glutamyltransferase levels and muscle spasms (2 patients each). Overall, 95.9% (95% confidence interval: 92.3, 99.4) of patients remained ulcer free at 1 year. Conclusion Long-term treatment with esomeprazole (20 mg once daily) is well tolerated and efficacious for preventing ulcer recurrence in Japanese NSAID users with a history of peptic ulcer. Trial registration ClinicalTrials.gov identifier NCT00595517. PMID:23530709

Background Rhabdomyolysis is a complex medical condition involving the rapid dissolution of damaged or injured skeletal muscle. Methods This review focuses on the epidemiology, pathophysiology, causes, presentation, diagnosis, complications, management, and anesthetic considerations related to rhabdomyolysis. Results Any form of muscle damage––and by extension any entity that causes muscle damage––can initiate rhabdomyolysis. One of the most important treatment goals when rhabdomyolysis is suspected is avoiding acute kidney injury. Conclusion All clinicians should be aware of common causes, diagnosis, and treatment options. PMID:25829882

Background Though common mental disorder (CMD) is highly prevalent among South Asian immigrant women, they rarely seek mental treatment. This may be due in part to the lack of conceptual synchrony between medical models of mental disorder and the social models of distress common in South Asian communities. Furthermore, common mental health screening and diagnostic measures may not adequately capture distress in this group. CBPR is ideally suited to help address measurement issues in CMD as well as develop culturally appropriate treatment models. Objectives To use participatory methods to identify an appropriate, culturally specific mental health syndrome and develop an instrument to measure this syndrome. Methods We formed a partnership between researchers, clinicians, and community members. The partnership selected a culturally specific model of emotional distress/ illness, “Tension,” as a focus for further study. Partners developed a scale to measure Tension and tested the new scale on 162 Bangladeshi immigrant women living in the Bronx. Results The 24-item “Tension Scale” had high internal consistency (alpha =0.83). In bivariate analysis, the scale significantly correlated in the expected direction with depressed as measured by the PHQ-2, age, education, self-rated health, having seen a physician in the past year, and other variables. Conclusions Using participatory techniques, we created a new measure designed to assess common mental disorder in an isolated immigrant group. The new measure shows excellent psychometric properties and will be helpful in the implementation of a community-based, culturally synchronous intervention for depression. We describe a useful strategy for the rapid development and field testing of culturally appropriate measures of mental distress and disorder. PMID:24375184

Background and Objectives Squamous cell carcinoma is the most common pathological type among the cancers of the larynx. Standard treatment for squamous cell carcinoma of the larynx is the combination of chemotherapy, radiotherapy, and laryngectomy. Pharyngocutaneous fistula is a common complication of laryngectomy. We hypothesized that decellularized and lyophilized human amnion/chorion membrane can be an effective, non‐invasive method of treating pharyngocutaneous fistula. Methods A total of 67 patients with laryngeal squamous cell carcinoma were retrospectively analyzed after treatment in a prospective trial. After preoperative chemotherapy, radiotherapy, and total or extended laryngectomy, primary wound healing occurred in 42 (62.7%) patients. Pharyngocutaneous fistula developed in 8 (11.9%) patients. Decellularized and lyophilized human amnion/chorion membrane grafts were used to reconstruct the fistulas. Results The average time for the full healing of the wound in all patients after transplantation of these grafts was 18 days. Conclusion The advantages of using these grafts over other existing methods of pharyngocutaneous fistula treatment are that they are non‐invasive, prevent donor morbidity, and enable management of the wound without using classical wound gauze.

Müller-Seubert, Wibke; Bührer, Gregor; Horch, Raymund E
2017-09-01
Background Fractures or fracture dislocations of the proximal interphalangeal joint often occur during sports or accidents. Dislocations of the PIP-joint are the most common ligamentary injuries of the hand. As this kind of injury is so frequent, hand surgeons and other physicians should be aware of the correct treatment. Objectives This paper summarises the most common injury patterns and the correct treatment of PIP-joint dislocations. Materials and Methods This paper reviews the current literature and describes the standardised treatment of PIP-joint dislocations. Results What is most important is that reposition is anatomically correct, and this should be controlled by X-ray examination. Depending on the instability and possible combination with other injuries (e. g. injury to the palmar plate), early functional physiotherapy of the joint or a short immobilisation period is indicated. Conclusions Early functional treatment of the injured PIP-joint, initially using buddy taping, is important to restore PIP-joint movement and function. Depending on the injury, joint immobilisation using a K-wire may be indicated. Detailed informed consent is necessary to explain to the patient the severity of the injury and possible complications, such as chronic functional disorders or development of arthrosis. © Georg Thieme Verlag KG Stuttgart · New York.

Purpose: To determine the patterns of care for lung cancer in Turkish radiation oncology centers. Methods and Materials: Questionnaire forms from 21 of 24 (87.5%) centers that responded were evaluated. Results: The most frequent histology was non-small cell lung cancer (NSCLC) (81%). The most common postoperative radiotherapy (RT) indications were close/(+) surgical margins (95%) and presence of pN2 disease (91%). The most common indications for postoperative chemotherapy (CHT) were '{>=} IB' disease (19%) and the presence of pN2 disease (19%). In Stage IIIA potentially resectable NSCLC, the most frequent treatment approach was neoadjuvant concomitant chemoradiotherapy (CHRT) (57%). In Stage IIIAmore » unresectable and Stage IIIB disease, the most frequent approach was definitive concomitant CHRT (91%). In limited SCLC, the most common treatment approach was concomitant CHRT with cisplatin+etoposide for cycles 1-3, completion of CHT to cycles 4-6, and finally prophylactic cranial irradiation in patients with complete response (71%). Six cycles of cisplatin + etoposide CHT and palliative thoracic RT, when required, was the most commonly used treatment (81%) in extensive SCLC. Sixty-two percent of centers did not have endobronchial brachytherapy (EBB) facilities. Conclusion: There is great variation in diagnostic testing, treatment strategies, indications for postoperative RT and CHT, RT features, and EBB availability for LC cases. To establish standards, national guidelines should be prepared using a multidisciplinary approach.« less

The method of instrumental variables (IV) is useful for estimating causal effects. Intuitively, it exploits exogenous variation in the treatment, sometimes called natural experiments or instruments. This study reviews the literature in health-services research and medical research that applies the method of instrumental variables, documents trends in its use, and offers examples of various types of instruments. A literature search of the PubMed and EconLit research databases for English-language journal articles published after 1990 yielded a total of 522 original research articles. Citations counts for each article were derived from the Web of Science. A selective review was conducted, with articles prioritized based on number of citations, validity and power of the instrument, and type of instrument. The average annual number of papers in health services research and medical research that apply the method of instrumental variables rose from 1.2 in 1991-1995 to 41.8 in 2006-2010. Commonly-used instruments (natural experiments) in health and medicine are relative distance to a medical care provider offering the treatment and the medical care provider's historic tendency to administer the treatment. Less common but still noteworthy instruments include randomization of treatment for reasons other than research, randomized encouragement to undertake the treatment, day of week of admission as an instrument for waiting time for surgery, and genes as an instrument for whether the respondent has a heritable condition. The use of the method of IV has increased dramatically in the past 20 years, and a wide range of instruments have been used. Applications of the method of IV have in several cases upended conventional wisdom that was based on correlations and led to important insights about health and healthcare. Future research should pursue new applications of existing instruments and search for new instruments that are powerful and valid.

An abdominal aortic aneurysm appears to be combined with aneurysmatic lesions of the common iliac arteries in 30-40% of cases. Like abdominal aortic aneurysms, aneurysms of the common iliac arteries rarely manifest themselves clinically. The lethality rate in case of rupture is comparable to that for rupture of an abdominal aortic aneurysm. During endoprosthetic repair of abdominal aortic aneurysms combined with aneurysms of the common iliac arteries, in order to prevent endoleaks and to improve the distal zone of fixation of endografts surgeons often resort to embolization of internal iliac arteries, which may lead to ischaemic postoperative complications. One of the methods of preserving pelvic blood flow is the use of an iliac branched endograft. A series of studies evaluating long-term outcomes demonstrated that this method proved to be both safe and effective, and with the suitable anatomy is a method of choice in high surgical risk patients. The present article deals with a clinical case report concerning bilateral endoprosthetic repair of the common iliac arteries, combined with endoprosthetic repair of an abdominal aortic aneurysm, with the description of technical peculiarities of implanting an iliac branched graft.
Can claudication be improved with medication?
Conners, Michael S; Money, Samuel R
2002-12-01
Intermittent claudication is a common disabling condition that affects approximately 5% to 15% of patients with atherosclerotic disease. Recommended treatment involves lifestyle modification and physical conditioning through the adoption of a regular exercise program. These methods of treatment often have been unsuccessful in the past because of noncompliance, in large part related to the relatively minor degree of improvement experienced by the patient. However, some recent trials have resulted in greater relative improvements in both pain-free and maximal walking distances in some patients treated with medication. Surgical and endovascular options offer greater degrees of improvement but also greater morbidity and should be reserved as treatment for severe claudication. The efficacies, as well as common adverse reactions associated with current medications used to treat patients with intermittent claudication are reviewed. Copyright 2002, Elsevier Science (USA).

One of the most common sexually transmitted infections is the herpes simplex virus (HSV) Type 2. Although the incidence of newborn infection is not as common as in adults, approximately 1,500 neonates are diagnosed annually with HSV infection. HSV can be detrimental to the life of a newborn, with morbidity and mortality rates of up to 65 percent. This article addresses the maternal and fetal complications of HSV and the impact of HSV on the newborn along with diagnostic evaluation methods. In addition, treatment options and evidence-based practices regarding HSV are defined. Despite growing technology and medical treatment for early identification of HSV, this virus remains challenging and can deeply impact the life of an infant and his or her family. Early diagnosis, treatment, and intervention of an infant with HSV are crucial to ensure the livelihood of the newborn.
Multivariate analysis of longitudinal rates of change.
Bryan, Matthew; Heagerty, Patrick J
2016-12-10
Longitudinal data allow direct comparison of the change in patient outcomes associated with treatment or exposure. Frequently, several longitudinal measures are collected that either reflect a common underlying health status, or characterize processes that are influenced in a similar way by covariates such as exposure or demographic characteristics. Statistical methods that can combine multivariate response variables into common measures of covariate effects have been proposed in the literature. Current methods for characterizing the relationship between covariates and the rate of change in multivariate outcomes are limited to select models. For example, 'accelerated time' methods have been developed which assume that covariates rescale time in longitudinal models for disease progression. In this manuscript, we detail an alternative multivariate model formulation that directly structures longitudinal rates of change and that permits a common covariate effect across multiple outcomes. We detail maximum likelihood estimation for a multivariate longitudinal mixed model. We show via asymptotic calculations the potential gain in power that may be achieved with a common analysis of multiple outcomes. We apply the proposed methods to the analysis of a trivariate outcome for infant growth and compare rates of change for HIV infected and uninfected infants. Copyright © 2016 John Wiley & Sons, Ltd.

Therapeutic methods for psychosomatic disorders in oto-rhino-laryngology
Decot, Elke
2005-01-01
Psychosomatic disorders such as tinnitus, acute hearing loss, attacks of dizziness, globus syndrome, dysphagias, voice disorders and many more are quite common in ear, nose and throat medicine. They are mostly caused by a number of factors, although the bio-psycho-social model does play an important role. Initial contact with a psychosomatically ill patient and compiling a first case history are important steps to psychosomatic oriented therapy. This contribution will sum up the most important otorhinolaryngological diseases with psychosomatic comorbidity and scientifically evaluated methods of treatment. The contribution will also introduce the reader to important psychosomatic treatment methods from psychotherapeutic relaxation techniques to talk therapy. To conclude, the contribution will discuss the criteria for outpatient as well as inpatient treatment and look at the advantages of psychosomatically oriented therapy, both for the patient and for the doctor.

Simple biogas desulfurization by microaeration - Full scale experience.
Jeníček, P; Horejš, J; Pokorná-Krayzelová, L; Bindzar, J; Bartáček, J

Hydrogen sulfide in biogas is common problem during anaerobic treatment of wastewater with high sulfate concentration (breweries, distilleries, etc.) and needs to be removed before biogas utilization. Physico-chemical desulfurization methods are energetically demanding and expensive compare to biochemical methods. Microaeration, i.e. dosing of small amount of air, is suitable and cost effective biochemical method of sulfide oxidation to elemental sulfur. It has been widely used in biogas plants, but its application in anaerobic reactors for wastewater treatment has been rarely studied or tested. The lack of full-scale experience with microaeration in wastewater treatment plants has been overcome by evaluating the results of seven microaerobic digesters in central Europe. The desulfurization efficiency has been more than 90% in most of the cases. Moreover, microaeration improved the degradability of COD and volatile suspended solids. Copyright © 2017 Elsevier Ltd.

The conditions in which Sr is fixed on calcite (the object of Geneva report P/395-USA-- 1958) are more closely studied and the work is extended to five fission products in the effluerts and to 17 common rocks and minerals. Although this fixation is not suitsble as a method of treating STE effluents (i.e., those from the effluent treatment plant at MIarcoule), the study shows that all the crystals considered are strongly contaminated by simple contact.

LATERAL EPICONDYLITIS OF THE ELBOW
Cohen, Marcio; da Rocha Motta Filho, Geraldo
2015-01-01
Lateral epicondylitis, also known as tennis elbow, is a common condition that is estimated to affect 1% to 3% of the population. The word epicondylitis suggests inflammation, although histological analysis on the tissue fails to show any inflammatory process. The structure most commonly affected is the origin of the tendon of the extensor carpi radialis brevis and the mechanism of injury is associated with overloading. Nonsurgical treatment is the preferred method, and this includes rest, physiotherapy, cortisone infiltration, platelet-rich plasma injections and use of specific immobilization. Surgical treatment is recommended when functional disability and pain persist. Both the open and the arthroscopic surgical technique with resection of the degenerated tendon tissue present good results in the literature. PMID:27047843

Increasing treatment costs of HF patients affect the initiation of appropriate treatment method. Divergent approaches to measure the costs of treatment and the lack of common cost indicators impede the comparison of therapy settings. In the context of the present meta-analysis, key cost indicators from the perspective of healthcare providers are to be identified, described, analyzed and quantified. This review helps narrowing down the cost indicators, which have the most significant economic impact on the total treatment costs of HF patients. Telemedical services are to be compared to standard therapy methods. The identification process was based on several steps. For the quantitative synthesis, we used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. An additional set of criteria was defined for the following qualitative analysis. 5 key cost indicators were identified with significant economic impact on the treatment costs of HF patients. 95% of the reported treatment costs could be captured based on the identified cost indicators.

Background Available drug treatment modalities may inadequately address social and structural contexts surrounding recovery efforts. Methods This mixed methods analysis drew on (1) surveys with female sex workers and their intimate male partners and (2) semi-structured interviews with a subsample of 41 couples (n = 82 individuals, 123 total interviews) in Northern Mexico. Descriptive and content analyses examined drug cessation and treatment experiences. Results Perceived need for drug treatment was high, yet only 35% had ever accessed services. Financial and institutional barriers (childcare needs, sex-segregated facilities) prevented partners from enrolling in residential programs together or simultaneously, leading to self-treatment attempts. Outpatient methadone was experienced more positively, yet financial constraints limited access and treatment duration. Relapse was common, particularly when one partner enrolled alone while the other continued using drugs. Conclusions Affordable, accessible, evidence-based drug treatment and recovery services that acknowledge social and structural contexts surrounding recovery are urgently needed for drug-involved couples.

OBJECTIVE To examine the long-term safety and efficacy of three antipsychotics in early-onset schizophrenia spectrum disorders (EOSS). METHOD Patients (age 8–19 years) who had improved during an 8-week, randomized double-blind acute trial of olanzapine, risperidone, or molindone (plus benztropine) were eligible to continue on the same medication for up to 44 additional weeks under double-blind conditions. Adjunctive medications were allowed following defined algorithms. Standardized symptom, safety, and functional assessments were conducted every 4 weeks. RESULTS Of the 116 youth randomized in the acute trial, 54 entered maintenance treatment (molindone, N=20; olanzapine, N=13; risperidone, N=21). Fourteen (26%) completed 44 weeks of treatment. Adverse effects (N=15), inadequate efficacy (N=14), or study non-adherence (N=8) were the most common reasons for discontinuation. The three treatment arms did not significantly differ in symptom reduction or time to discontinuation. Akathisia was more common with molindone and elevated prolactin concentrations more common with risperidone. Although weight gain and metabolic adverse events had occurred more often with olanzapine and risperidone during the acute trial, no significant between-drug differences emerged in most of these parameters during maintenance treatment. CONCLUSIONS Only 12 % of youth with EOSS continued on their originally randomized treatment at 52 weeks. No agent demonstrated superior efficacy, and all were associated with side effects, including weight gain. Improved treatments are needed for EOSS. PMID:20494268
What is the impact of comorbid depression on adolescent substance abuse treatment?
Hersh, Jacqueline; Curry, John F; Kaminer, Yifrah
2014-01-01
Substance use disorders (SUDs) are among the most common psychiatric diagnoses in adolescents. Some research suggests that comorbid depression in adolescents with SUD is associated with increased likelihood of alcohol dependence, poorer social competence, and greater risk for suicide attempts. However, little is known about how depression influences adolescent substance abuse treatment retention and outcomes. This review aimed to summarize the effects of comorbid depression on treatment retention and outcomes across 13 adolescent SUD treatment studies. RESULTS indicated that depression has a mixed relationship with treatment retention and outcomes, exerting a negative, positive, or nonsignificant effect depending on aspects of the study. More research needs to be done, particularly addressing the potential mediators and moderators of the relationship between depression and SUD outcomes. Importantly, recognizing that the studies varied widely in hypotheses and research methods, the field needs to develop more standardized methods to allow for a clearer understanding of the role of comorbid depression.

Alzheimer disease (Alzheimer Disease, AD) is one of the most common type in senile dementia. Its main pathological features were that a large number of senile plaques gathered in brain extracellular and tangles fibrosis appeared in nerve cells. Currently, the pathogenesis of AD is still uncertain, and scale investigation and combined brain CT, MRI data were analyzed mainly for clinical diagnosis. Mitigation and improvement of the nervous system activity to interfere with the subsequent behavior of the patients are the main methods for treatment. In clinical no drug can really prevent and cure AD. From the view point of Tibetan medicine studies, Tibetan medicine RNSP has effect on improving memory and repairing the neurons in the brain. In this study, we combined the characteristics of AD pathology, pathogenesis, diagnosis and treatment methods to explore the feasibility of Tibetan medicine RNSP for the treatment of AD to provide new ideas for the diagnosis and treatment of AD.

Martins, Regina Helena Garcia; Branco, Anete; Tavares, Elaine Lara Mendes; Gramuglia, Andrea Cristina Jóia
2013-09-01
Common among children, vocal symptoms are a cause of concern for parents who seek elucidation of their diagnosis and treatment. Vocal nodules are the major cause of dysphonias in children and are related to vocal abuse. We conducted a literature review considering clinical, physiopathological, epidemiological, and histological aspects of vocal nodules, as well as diagnostic methods, highlighting the main studies addressing this issue. The controversial points of treatments were also discussed.

Clostridium difficile infection is increasing in incidence, severity, and mortality. Treatment options are limited and appear to be losing efficacy. Recurrent disease is especially challenging; extended treatment with oral vancomycin is becoming increasingly common but is expensive. Fecal microbiota transplantation (FMT) is safe, inexpensive, and effective; according to case and small series reports, about 90% of patients are cured. We discuss the rationale, methods, and use of FMT. PMID:21871249
Implicit treatment of diffusion terms in lower-upper algorithms

Shih, T. I.-P.; Steinthorsson, E.; Chyu, W. J.
1993-01-01
A method is presented which allows diffusion terms to be treated implicitly in the lower-upper (LU) algorithm (which is a commonly used method for solving 'compressible' Euler and Navier-Stokes equations) so that the algorithm's good stability properties will not be impaired. The new method generalizes the concept of LU factorization from that associated with the sign of eigenvalues to that associated with backward- and forward-difference operators without regard to eigenvalues. The method is verified in a turbulent boundary layer study.

Observational comparative effectiveness and safety studies are often subject to immortal person-time, a period of follow-up during which outcomes cannot occur because of the treatment definition. Common approaches, like excluding immortal time from the analysis or naïvely including immortal time in the analysis, are known to result in biased estimates of treatment effect. Other approaches, such as the Mantel-Byar and landmark methods, have been proposed to handle immortal time. Little is known about the performance of the landmark method in different scenarios. We conducted extensive Monte Carlo simulations to assess the performance of the landmark method compared with other methods in settings that reflect realistic scenarios. We considered four landmark times for the landmark method. We found that the Mantel-Byar method provided unbiased estimates in all scenarios, whereas the exclusion and naïve methods resulted in substantial bias when the hazard of the event was constant or decreased over time. The landmark method performed well in correcting immortal person-time bias in all scenarios when the treatment effect was small, and provided unbiased estimates when there was no treatment effect. The bias associated with the landmark method tended to be small when the treatment rate was higher in the early follow-up period than it was later. These findings were confirmed in a case study of chronic obstructive pulmonary disease. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.
Music therapy as a non-pharmacological treatment for epilepsy.
Liao, Huan; Jiang, Guohui; Wang, Xuefeng
2015-01-01
Epilepsy is one of the most common neurological diseases. Currently, the primary methods of treatment include pharmacological and surgical treatment. However, approximately one-third of patients exhibit refractory epilepsy. Therefore, a novel approach to epilepsy treatment is necessary. Several studies have confirmed that music therapy can be effective at reducing seizures and epileptiform discharges, thus providing a new option for clinicians in the treatment of epilepsy. Although the underlying mechanism of music therapy is unknown, it may be related to resonance, mirror neurons, dopamine pathways and parasympathetic activation. Large sample, multicenter, randomized double-blind and more effectively designed studies are needed for future music therapy studies.
Onychomycosis: diagnosis and systemic treatment.
Milles, C L; Riley, P A; Kessenich, C R
1998-12-01
Onychomycosis, a persistent fungal infection affecting the toenails and fingernails, can interfere with standing, walking, and exercising. Associated physical impairments can result in paresthesia, pain, discomfort, and loss of manual dexterity. Patients may also suffer from loss of self-esteem and social interaction. A definitive diagnosis is crucial for effective treatment, because many other skin and nail disorders mimic onychomycosis. Diagnosis involves microscopic potassium hydroxide preparation, cultures, nail biopsy, and histologic analysis. Treatment can include topical and systemic antifungal therapies as well as nonpharmaceutical methods. This paper discusses pathophysiology, diagnosis, and treatment options for this common nail dystrophy, including the newer antifungal medications now available.

Attention-deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder that affects the child and adolescent population. It is characterized by impairment in attention/concentration, hyperactivity, and impulsivity, all of which can impact performance of athletes. ADHD treatment within the athletic population is a unique challenge. The research in this field has been relatively limited. The National Collegiate Athletic Association and International Olympic Committee both regulate the use of psychostimulants for treatment of ADHD due to their performance-enhancing effects. In this article, authors have discussed the screening methods, pharmacological treatment, side effects, and behavioral approaches for the treatment of ADHD in adolescent athletes. PMID:24987666

Scabies is an ectoparasite caused by the mite Sarcoptes scabiei var hominis, an obligate human parasite. There are about 300 million cases of scabies in the world each year. Common predisposing factors are overcrowding, immigration, poor hygiene, poor nutritional status, homelessness, dementia, and sexual contact. Direct skin-to-skin contact between 15 and 20 minutes is needed to transfer the mites from one person to another. The diagnosis suspected with a clinical history of itch, worse at night, affecting other family members, clinical distribution, and appearance. Definite diagnosis relies on microscopic identification of the mites, eggs, or fecal pellets with 10% potassium hydroxide, ink enhancement, tetracycline fluorescence tests, or mineral oil; other methods include: epiluminescence light microscopy and S. scabiei DNA. The most commonly used treatment modalities are permethrin and ivermectin. Persistence of symptoms for 2-6 weeks after successful treatment is common. Most recurrences are because of reinfection from untreated contacts.
Delayed reconstruction of lateral complex structures of the ankle
Slater, Gordon L; Pino, Alejandro E; O’Malley, Martin
2011-01-01
Lateral ankle instability is one of the most common and well-recognized conditions presenting to foot and ankle surgeons. It may exist as an isolated entity or in conjunction with other concomitant pathology, making it important to appropriately diagnose and identify other conditions that may need to be addressed as part of treatment. These associated conditions may be a source of chronic pain, even when the instability has been appropriately treated, or may lead to failure of treatment by predisposing the patient to ankle inversion injuries. The primary goal of this editorial is to provide a brief summary of the common techniques used in the delayed reconstruction of lateral ankle ligamentous injuries and present a method we have successfully employed for over 15 years. We will also briefly discuss the diagnosis and treatment of the more common associated conditions, which are important to identify to achieve satisfactory results for the patient. We present the outcomes of 250 consecutive reconstructions performed over the last 10 years and describe our operative technique for addressing lateral ankle ligamentous injuries. PMID:22474633
Diagnosis and Treatment of Common Forms of Tremor
Puschmann, Andreas; Wszolek, Zbigniew K.
2014-01-01
Tremor is the most common movement disorder presenting to an outpatient neurology practice and is defined as a rhythmical, involuntary oscillatory movement of a body part. The authors review the clinical examination, classification, and diagnosis of tremor. The pathophysiology of the more common forms of tremor is outlined, and treatment options are discussed. Essential tremor is characterized primarily by postural and action tremors, may be a neurodegenerative disorder with pathologic changes in the cerebellum, and can be treated with a wide range of pharmacologic and nonpharmacologic methods. Tremor at rest is typical for Parkinson’s disease, but may arise independently of a dopaminergic deficit. Enhanced physiologic tremor, intention tremor, and dystonic tremor are discussed. Further differential diagnoses described in this review include drug- or toxin-induced tremor, neuropathic tremor, psychogenic tremor, orthostatic tremor, palatal tremor, tremor in Wilson’s disease, and tremor secondary to cerebral lesions, such as Holmes’ tremor (midbrain tremor). An individualized approach to treatment of tremor patients is important, taking into account the degree of disability, including social embarrassment, which the tremor causes in the patient’s life.

Systemic and topical drugs for aging skin.
Kockaert, Michael; Neumann, Martino
2003-08-01
The rejuvenation of aging skin is a common desire for our patients, and several options are available. Although there are some systemic methods, the most commonly used treatments for rejuvenation of the skin are applied topically. The most frequently used topical drugs include retinoids, alpha hydroxy acids (AHAs), vitamin C, beta hydroxy acids, anti-oxidants, and tocopherol. Combination therapy is frequently used; particularly common is the combination of retinoids and AHAs. Systemic therapies available include oral retinoids and vitamin C. Other available therapies such as chemical peels, face-lifts, collagen, and botulinum toxin injections are not discussed in this article.
Missing Data in Alcohol Clinical Trials with Binary Outcomes.

Missing data are common in alcohol clinical trials for both continuous and binary end points. Approaches to handle missing data have been explored for continuous outcomes, yet no studies have compared missing data approaches for binary outcomes (e.g., abstinence, no heavy drinking days). This study compares approaches to modeling binary outcomes with missing data in the COMBINE study. We included participants in the COMBINE study who had complete drinking data during treatment and who were assigned to active medication or placebo conditions (N = 1,146). Using simulation methods, missing data were introduced under common scenarios with varying sample sizes and amounts of missing data. Logistic regression was used to estimate the effect of naltrexone (vs. placebo) in predicting any drinking and any heavy drinking outcomes at the end of treatment using 4 analytic approaches: complete case analysis (CCA), last observation carried forward (LOCF), the worst case scenario (WCS) of missing equals any drinking or heavy drinking, and multiple imputation (MI). In separate analyses, these approaches were compared when drinking data were manually deleted for those participants who discontinued treatment but continued to provide drinking data. WCS produced the greatest amount of bias in treatment effect estimates. MI usually yielded less biased estimates than WCS and CCA in the simulated data and performed considerably better than LOCF when estimating treatment effects among individuals who discontinued treatment. Missing data can introduce bias in treatment effect estimates in alcohol clinical trials. Researchers should utilize modern missing data methods, including MI, and avoid WCS and CCA when analyzing binary alcohol clinical trial outcomes.

Zhao, Yongdong; Dedeoglu, Fatma; Ferguson, Polly J; Lapidus, Sivia K; Laxer, Ronald M; Bradford, Miranda C; Li, Suzanne C
2017-01-01
Background/Purpose . Understanding the practices of pediatric rheumatologists in diagnosing and treating chronic nonbacterial osteomyelitis (CNO) can provide important information to guide the development of consensus treatment plans. The objectives of this study were to determine physicians' approaches to (1) diagnosing and monitoring CNO, (2) ordering a bone biopsy, and (3) making treatment decisions. Methods . A survey was distributed among members of the Childhood Arthritis and Rheumatology Research Alliance using a web-based questionnaire. Results . 121 of 277 (41%) attending physician members completed the survey. Plain radiographs (89%) were most commonly used followed by regional MRI (78%), bone scintigraphy (43%), and whole-body MRI (36%). The top three reasons for performing a biopsy were constitutional findings (66%), unifocal bone lesions (64%), and nocturnal bone pain (45%). Nearly all responders (95%) prescribed nonsteroidal anti-inflammatory drugs (NSAIDs) as initial therapy. For patients who failed NSAID treatment, methotrexate (67%), tumor necrosis factor inhibitors (65%), and bisphosphonates (46%) were the next most commonly used treatments. The presence of a spinal lesion increased the use of bisphosphonate treatment. Conclusion . The diagnostic approach and disease activity monitoring for CNO varied among surveyed physicians. Our survey findings provided important background for the development of consensus treatment plans for CNO.
Premature ejaculation: do we have effective therapy?
Serefoglu, Ege Can; Saitz, Theodore R.; Trost, Landon
2013-01-01
Introduction Premature ejaculation (PE) is the most common sexual dysfunction, with the majority of PE patients remaining undiagnosed and undertreated. Despite its prevalence, there is a current paucity of data regarding available treatment options and mechanisms. The objective of the current investigation is to review and summarize pertinent literature on therapeutic options for the treatment of PE, including behavioral/psychologic, oral pharmacotherapy, and surgery. Methods A pubmed search was conducted on articles reporting data on available treatment options for PE. Articles describing potential mechanisms of action were additionally included for review. Preference was given towards randomized, controlled trials, when available. Results PE remains an underdiagnosed and undertreated disease process, with limited data available regarding potential underlying mechanisms and long-term outcomes of treatment options. Psychological/behavioral therapies, including the stop-start, squeeze, and pelvic floor rehabilitation techniques have demonstrated improvements in short-term series, with decreased efficacy with additional follow-up. Topical therapies, which are commonly utilized result in prolonged intravaginal ejaculatory latency time (IELT) at the expense of potential penile/vaginal Hypothesia. Oral therapies similarly demonstrate improved IELTs with variable side effect profiles and include selective serotonin reuptake inhibitors (daily or on demand), phosphodiesterase-5 inhibitors, alpha-1 adrenergic antagonists, and tramadol. Alternative therapies such as acupuncture have shown benefits in limited studies. Surgery is not commonly performed and is not recommended by available guidelines. Conclusions PE is a common condition, with limited data available regarding its underlying pathophysiology and treatment. Available therapies include topical, oral, behavioral/psychologic modification, or a combination thereof. Additional research is required to assess the optimal treatment strategies and algorithms as well as to better define the mechanisms for PE and its management. PMID:26816723

Background: Common mental disorders, such as mood, anxiety, and substance use disorders, are significant contributors to disability globally, including India. Available research is, however, limited by methodological issues and heterogeneities. Aim: The present paper focuses on the 12-month prevalence and 12-month treatment for anxiety, mood, and substance use disorders in India. Materials and Methods: As part of the World Health Organization World Mental Health (WMH) Survey Initiative, in India, the study was conducted at eleven sites. However, the current study focuses on the household sample of 24,371 adults (≥18 years) of eight districts of different states, covering rural and urban areas. Respondents were interviewed face-to-face using the WMH Composite International Diagnostic Interview after translation and country-specific adaptations. Diagnoses were generated as per the International Classification of Diseases, 10th edition, Diagnostic Criteria for Research. Results: Nearly 49.3% of the sample included males. The 12-month prevalence of common mental disorders was 5.52% - anxiety disorders (3.41%), mood disorders (1.44%), and substance use disorders (1.18%). Females had a relatively higher prevalence of anxiety and mood disorders, and lower prevalence of substance use disorders than males. The 12-month treatment for people with common mental disorders was 5.09% (range 1.66%–11.55% for individual disorders). The survey revealed a huge treatment gap of 95%, with only 5 out of 100 individuals with common mental disorders receiving any treatment over the past year. Conclusion: The survey provides valuable data to understand the mental health needs and treatment gaps in the Indian population. Despite the 12-month prevalence study being restricted to selected mental disorders, these estimates are likely to be conservative due to under-reporting or inadequate detection due to cultural factors.

2015-06-01
New behavioral treatment methods, including dichoptic training, perceptual learning, and video gaming, have been proposed to improve visual function in adult amblyopia. Here, we conducted a meta-analysis of these methods to investigate the factors involved in amblyopia recovery and their clinical significance. Mean and individual participant data meta-analyses were performed on 24 studies using the new behavioral methods in adults. Studies were identified using PubMed, Google Scholar, and published reviews. The new methods yielded a mean improvement in visual acuity of 0.17 logMAR with 32% participants achieving gains ≥ 0.2 logMAR, and a mean improvement in stereo sensitivity of 0.01 arcsec-1 with 42% of participants improving ≥2 octaves. The most significant predictor of treatment outcome was visual acuity at the onset of treatment. Participants with more severe amblyopia improved more on visual acuity and less on stereo sensitivity than those with milder amblyopia. Better initial stereo sensitivity was a predictor of greater gains in stereo sensitivity following treatment. Treatment type, amblyopia type, age, and training duration did not have any significant influence on visual and stereo acuity outcomes. Our analyses showed that some participants may benefit from the new treatments; however, clinical trials are required to confirm these findings. Despite the diverse nature of the new behavioral methods, the lack of significant differences in visual and stereo sensitivity outcomes among them suggests that visual attention-a common element among the varied treatment methods-may play an important role in amblyopia recovery.

Conventional methods for the aetiological diagnosis of community-acquired pneumonia (CAP) are often insufficient owing to low sensitivity and the long wait for the results of culture and particularly serology, and it often these methods establish a diagnosis in only half of cases. To evaluate the most common bacterial and viral agents in CAP using a fast responsive PCR method and investigate the relationship between clinical/laboratory features and aetiology, thereby contributing to empirical antibiotic selection and reduction of treatment failure. In children aged 4-15 years consecutively admitted with a diagnosis of CAP, the 10 most commonly detected bacterial and 12 most commonly detected viral agents were investigated by induced sputum using bacterial culture and multiplex PCR methods. Clinical and laboratory features were compared between bacterial and viral pneumonia. In 78 patients, at least one virus was detected in 38 (48.7%) and at least one bacterium in 32 (41%). In addition, both bacteria and viruses were detected in 16 (20.5%) patients. Overall, the agent detection rate was 69.2%. The most common viruses were respiratory syncytial virus and influenza and the most frequently detected bacteria were S. pneumoniae and H. influenzae. PCR was superior to culture for bacterial isolation (41% vs 13%, respectively). Fever, wheezing and radiological features were not helpful in differentiating between bacterial and viral CAP. White blood cell count, CRP and ESR values were significantly higher in the bacterial/mixed aetiology group than in the viral aetiology group. In CAP, multiplex PCR is highly reliable, superior in detecting multiple pathogens and rapidly identifies aetiological agents. Clinical features are poor for differentiation between bacterial and viral infections. The use of PCR methods allow physicians to provide more appropriate antimicrobial therapy, resulting in a better response to treatment, and it may be possible for use as a routine service if costs can be reduced.

In patients with diabetes, foot complications remain one of the main health issues, with ulcers representing one of the most common. These ulcerations originate from repetitive trauma on a foot with neuropathy. Inadequate care of the diabetic foot may lead to one of the gravest complications of the diabetic foot: amputation. The key to the treatment of the diabetic foot is the control of comorbidities (glucose levels and vascular disease), debridement, exudate control with the available modern dressings, treatment of infection, and offloading the affected foot. A common error in this basic treatment is the method used for offloading, leading to delayed healing as a result, and maybe even amputation. For this purpose we propose the total contact cast considered the "gold standard" in diabetic foot offloading. The objective of the present review is to present the existing evidence in the medical literature on the effectiveness of its use for healing diabetic foot ulcers and hence preventing amputations.
[Prevention and management of refeeding syndrome in patients with chronic critical illness].
Chen, Jun; Fan, Chaogang

Nutritional support is an important means to treat the patients with chronic critical illness for commonly associated malnutrition. Refeeding syndrome is a serious complication during the process, mainly manifested as severe electrolyte with hypophosphataemia being the most common. Refeeding syndrome is not uncommon but it is often ignored. In our future clinical work, we need to recognize this chinical situation and use preventative and treatment measures. According to NICE clinical nutrition guideline, we discussed the risk factors, treatment methods and preventive measures of refeeding syndrome in patients with chronic critical illness. We argued that for patients with high risk refeeding syndrome, nutritional support treatment should be initially low calorie and slowly increased to complete requirement. Circulation capacity should be recovered, fluid balance must be closely monitored and supplement of vitamins, microelement, electrolytes should be noted. After the emergence of refeeding syndrome, we should reduce or even stop the calorie intake, give an active treatment for electrolyte disorder, provide vitamin B, and maintain the functions of multiple organs.

Chemicothermal treatment processes are widely used in engineering to improve the working lives of important components, of which the most common is nitrocementation. That process has been applied at the Volga Automobile Plant mainly to sprockets in gear transmissions, which need high hardness and wear resistance in the surfaces with relatively ductile cores. Although various forms of chemicothermal treatment are widely used, there has been no universal method of evaluating the strengths of gear wheels. Standard methods of estimating strength ({sigma}{sub u}, {sigma}{sub t}, {sigma}{sub b}, and hardness) have a major shortcoming: They can determine only the characteristics of themore » cores for case-hardened materials. Here we consider a method of impact bending test, which enables one to evaluate the actual strength of gear teeth.« less

Causal analysis of ordinal treatments and binary outcomes under truncation by death.
Wang, Linbo; Richardson, Thomas S; Zhou, Xiao-Hua
2017-06-01
It is common that in multi-arm randomized trials, the outcome of interest is "truncated by death," meaning that it is only observed or well-defined conditioning on an intermediate outcome. In this case, in addition to pairwise contrasts, the joint inference for all treatment arms is also of interest. Under a monotonicity assumption we present methods for both pairwise and joint causal analyses of ordinal treatments and binary outcomes in presence of truncation by death. We illustrate via examples the appropriateness of our assumptions in different scientific contexts.

The anterior cerebral artery is a common location of intracranial aneurysms. The standard coil embolization technique is limited by its inability to occlude wide-neck aneurysms. Stent deployment across the aneurysm neck supports the coil mass inside the aneurysmal sac, and furthermore, has an effect on local hemodynamic and biologic changes. In this article, various management strategies and techniques as well as angiographic outcomes and complications related to stent-assisted endovascular treatment of anterior communicating artery aneurysms are presented. This treatment method is safe and associated with low morbidity and mortality rates.

In Situ Treatment of Chromate Contaminated Groundwater Jonathan S. Fruchter Pacific Northwest National Laboratory Abstract of paper published in Environmental Science and Technology, 2002 Although not as common as solvent or fuel products contamination, chromate (chromium (VI)) contamination of groundwater is relatively widespread. Chromate has a variety of industrial uses, including chrome plating, steel making, and use as a corrosion inhibitor, wood preservative, well-drilling fluid additive, biocide, and as a pigment in paints and primers. EPA has estimated that as many as 1300 sites in the United States may have groundwater contaminated with chromate. The paper discusses a number ofmore » approaches to in situ treatment of chromate contamination in groundwater aquifers. The approaches include various types of chemical treatments, biological treatments and natural attenuation. The strengths and weaknesses of each method are discussed and compared. Field examples of two types of chemical treatment, in situ redox manipulation and chemically enhanced pump and treat are presented. It is concluded that in situ methods show promise, but can be difficult to implement due to site-specific conditions and limited long-term experience with these methods. As more performance and cost data are acquired for the demonstrations that are ongoing, and continuing research increases our understanding of subsurface processes, in situ treatment methods for chromium (VI) contamination in groundwater should gain wider acceptance.« less
A Modeled Analysis of Telehealth Methods for Treating Pressure Ulcers after Spinal Cord Injury

Home telehealth can improve clinical outcomes for conditions that are common among patients with spinal cord injury (SCI). However, little is known about the costs and potential savings associated with its use. We developed clinical scenarios that describe common situations in treatment or prevention of pressure ulcers. We calculated the cost implications of using telehealth for each scenario and under a range of reasonable assumptions. Data were gathered primarily from US Department of Veterans Affairs (VA) administrative records. For each scenario and treatment method, we multiplied probabilities, frequencies, and costs to determine the expected cost over the entire treatment period. We generated low-, medium-, and high-cost estimates based on reasonable ranges of costs and probabilities. Telehealth care was less expensive than standard care when low-cost technology was used but often more expensive when high-cost, interactive devices were installed in the patient's home. Increased utilization of telehealth technology (particularly among rural veterans with SCI) could reduce the incidence of stage III and stage IV ulcers, thereby improving veterans' health and quality of care without increasing costs. Future prospective studies of our present scenarios using patients with various healthcare challenges are recommended. PMID:22969798
Causes and Recommendations for Unanticipated Ink Retention Following Tattoo Removal Treatment
Chen, Cynthia L.; Desai, Alpesh; Desai, Tejas
2013-01-01
While placement of ink into the skin is a long-standing tradition, patients are now seeking tattoo removal on a more frequent basis. Once considered acceptable removal options, tattoo ink removal via physical destruction included dermabrasion, chemical destruction, salabrasion, thermal destruction, and cryotherapy. Now these options are used extremely infrequently. These modalities provided unpredictable results and often required prolonged healing times and left patients with skin discoloration, pain, scarring, and ink retention. Even the widely adopted use of lasers, now considered the gold standard method, offers some level of unpredictability surrounding the natural progression of ink resolution. Multiple factors need to be taken into consideration when successfully removing tattoo pigment including the modalities used, number and frequency of treatments, proper device technique, and physiological barriers to tattoo removal. This paper serves to elucidate the common causes of ink retention following tattoo removal treatment with recommendations on how best to address this relatively common occurrence. PMID:23882312
Total knee arthroplasty and fractures of the tibial plateau
Softness, Kenneth A; Murray, Ryan S; Evans, Brian G
2017-01-01
Tibial plateau fractures are common injuries that occur in a bimodal age distribution. While there are various treatment options for displaced tibial plateau fractures, the standard of care is open reduction and internal fixation (ORIF). In physiologically young patients with higher demand and better bone quality, ORIF is the preferred method of treating these fractures. However, future total knee arthroplasty (TKA) is a consideration in these patients as post-traumatic osteoarthritis is a common long-term complication of tibial plateau fractures. In older, lower demand patients, ORIF is potentially less favorable for a variety of reasons, namely fixation failure and the need for delayed weight bearing. In some of these patients, TKA can be considered as primary mode of treatment. This paper will review the literature surrounding TKA as both primary treatment and as a salvage measure in patients with fractures of the tibial plateau. The outcomes, complications, techniques and surgical challenges are also discussed. PMID:28251061

In the treatment of mandibular condyle fracture, conservative treatment using closed reduction or surgical treatment using open reduction can be used. Management of mandibular condylar fractures remains a source of ongoing controversy in oral and maxillofacial trauma. For each type of condylar fracture,the treatment method must be chosen taking into consideration the presence of teeth, fracture height, patient'sadaptation, patient's masticatory system, disturbance of occlusal function, and deviation of the mandible. In the past, closed reduction with concomitant active physical therapy conducted after intermaxillary fixation during the recovery period had been mainly used, but in recent years, open treatment of condylar fractures with rigid internal fixation has become more common. The objective of this review was to evaluate the main variables that determine the choice of an open or closed method for treatment of condylar fractures, identifying their indications, advantages, and disadvantages, and to appraise the current evidence regarding the effectiveness of interventions that are used in the management of fractures of the mandibular condyle.

Cisplatin (CDDP) has been commonly used as a chemotherapeutic drug, mainly used for the treatment of malignant epithelial cell tumors. We have developed a new method based on innovative lipid calcium phosphate, which encapsulated hydrophobic drugs to form liposomal nanoparticles. Esophageal cancer xenograft model was used to investigate the efficacy of liposomal nanoparticles. and it showed good therapeutic efficacy with lower side effects. Liposomal nanoparticles exhibited a better therapeutic effect than that of conventional CDDP.

Equine recurrent uveitis (ERU) is one of the most common causes of blindness in horses. Until recently, treatment of this condition consisted only of symptomatic therapy, typically with steroidal and nonsteroidal medications. A better understanding of the disease process(es) has permitted new medical and surgical therapies that have recently been described. This article highlights clinical features of ERU, the causes of ERU, and new management and treatment options for horses with ERU.

Quantifying fibrosis in head and neck cancer treatment: An overview.
Moloney, Emma C; Brunner, Markus; Alexander, Ashlin J; Clark, Jonathan
2015-08-01
Fibrosis is a common late complication of radiotherapy and/or surgical treatment for head and neck cancers. Fibrosis is difficult to quantify and formal methods of measure are not well recognized. The purpose of this review was to summarize the methods available to quantify neck fibrosis. A PubMed search of articles was carried out using key words "neck" and "fibrosis." Many methods have been used to assess fibrosis, however, there is no preferred methodology. Specific to neck fibrosis, most studies have relied upon hand palpation rating scales. Indentation and suction techniques have been used to mechanically quantify neck fibrosis. There is scope to develop applications of ultrasound, dielectric, bioimpedance, and MRI techniques for use in the neck region. Quantitative assessment of neck fibrosis is sought after in order to compare treatment regimens and improve quality of life outcomes in patients with head and neck cancer. © 2014 Wiley Periodicals, Inc.

Objectives We explored attitudes about prevention, screening and treatment of hepatitis B virus (HBV) infection in Chinese, Korean and Vietnamese communities. Methods We use qualitative methods in 12 focus groups (n=113) of adults who self-reported their ethnicity to be Chinese, Korean, or Vietnamese. We use grounded theory (i.e., consensus-building between co-coders about recurring, emerging themes) for analysis. Results Diet, nutrition, fatigue and stress were misidentified as HBV causes. Improving hygiene, diet, exercise, and holistic methods were misidentified as viable HBV prevention methods. Common screening problems included not affording test and not understanding test results. Participants shared reasons for using complementary and alternative medicine—when Western medicine fails or becomes unaffordable. Participants sought information from medical providers and fellow community members, but also from the internet. Conclusions Many of the attitudes and opinions that emerged may deter participation in HBV screening, prevention and treatment, insofar as community members may factor them into healthcare decision-making, choose alternative but ineffective methods of prevention and treatment, and undervalue the benefits of screening. More patient education in both traditional and new media is necessary for clarifying transmission, screening and treatment misunderstandings. PMID:22302653

Little is known about how Latinos with post-traumatic stress disorder (PTSD) understand their illness and their preferences for mental health treatment. To understand the illness beliefs and treatment preferences of Latino immigrants with PTSD. Semi-structured, face-to-face interviews. Sixty foreign-born, Latino adults recruited from five primary care centers in New York and New Jersey and screened for PTSD. Content analytic methods identified common themes, their range, and most frequent or typical responses. Participants identified their primary feelings as sadness, anxiety, nervousness, and fear. The most common feeling was "sad" (triste). Other words frequently volunteered were "angry" (enojada), "nervous" (nerviosa), and "scared" (miedo). Participants viewed their PTSD as impairing health and functioning. They ascribed their somatic symptoms and their general medical problems to the "stress" from the trauma and its consequences on their lives. The most common reason participants volunteered for their work and school functioning being impaired was their poor concentration, often due to intrusive thoughts. Most expressed their desire to receive mental health treatment, to receive it within their primary care center, and preferred psychotherapy over psychotropic medications. Among participants who did not report wanting treatment, most said it was because the trauma was "in the past." Clinicians may consider enquiring about PTSD in Latino patients who report feeling sad, anxious, nervous, or fearful. Our study suggests topics clinicians may include in the psychoeducation of patients with PTSD.

Missing outcome data are commonly encountered in randomized controlled trials and hence may need to be addressed in a meta-analysis of multiple trials. A common and simple approach to deal with missing data is to restrict analysis to individuals for whom the outcome was obtained (complete case analysis). However, estimated treatment effects from complete case analyses are potentially biased if informative missing data are ignored. We develop methods for estimating meta-analytic summary treatment effects for continuous outcomes in the presence of missing data for some of the individuals within the trials. We build on a method previously developed for binary outcomes, which quantifies the degree of departure from a missing at random assumption via the informative missingness odds ratio. Our new model quantifies the degree of departure from missing at random using either an informative missingness difference of means or an informative missingness ratio of means, both of which relate the mean value of the missing outcome data to that of the observed data. We propose estimating the treatment effects, adjusted for informative missingness, and their standard errors by a Taylor series approximation and by a Monte Carlo method. We apply the methodology to examples of both pairwise and network meta-analysis with multi-arm trials. © 2014 The Authors. Statistics in Medicine Published by John Wiley & Sons Ltd.

In medical studies of time-to-event data, nonproportional hazards and dependent censoring are very common issues when estimating the treatment effect. A traditional method for dealing with time-dependent treatment effects is to model the time-dependence parametrically. Limitations of this approach include the difficulty to verify the correctness of the specified functional form and the fact that, in the presence of a treatment effect that varies over time, investigators are usually interested in the cumulative as opposed to instantaneous treatment effect. In many applications, censoring time is not independent of event time. Therefore, we propose methods for estimating the cumulative treatment effect in the presence of nonproportional hazards and dependent censoring. Three measures are proposed, including the ratio of cumulative hazards, relative risk, and difference in restricted mean lifetime. For each measure, we propose a double inverse-weighted estimator, constructed by first using inverse probability of treatment weighting (IPTW) to balance the treatment-specific covariate distributions, then using inverse probability of censoring weighting (IPCW) to overcome the dependent censoring. The proposed estimators are shown to be consistent and asymptotically normal. We study their finite-sample properties through simulation. The proposed methods are used to compare kidney wait-list mortality by race. © 2010, The International Biometric Society.
A comparison of multiple imputation methods for incomplete longitudinal binary data.
Yamaguchi, Yusuke; Misumi, Toshihiro; Maruo, Kazushi
2018-01-01
Longitudinal binary data are commonly encountered in clinical trials. Multiple imputation is an approach for getting a valid estimation of treatment effects under an assumption of missing at random mechanism. Although there are a variety of multiple imputation methods for the longitudinal binary data, a limited number of researches have reported on relative performances of the methods. Moreover, when focusing on the treatment effect throughout a period that has often been used in clinical evaluations of specific disease areas, no definite investigations comparing the methods have been available. We conducted an extensive simulation study to examine comparative performances of six multiple imputation methods available in the SAS MI procedure for longitudinal binary data, where two endpoints of responder rates at a specified time point and throughout a period were assessed. The simulation study suggested that results from naive approaches of a single imputation with non-responders and a complete case analysis could be very sensitive against missing data. The multiple imputation methods using a monotone method and a full conditional specification with a logistic regression imputation model were recommended for obtaining unbiased and robust estimations of the treatment effect. The methods were illustrated with data from a mental health research.

The purpose was to evaluate the incidence, etiology, site and patterns, management and treatment methods, and outcome of pediatric patients with mandibular fractures. Pediatric patients (1.5-16 years old) with mandibular fractures, treated at the Soroka University Medical Center were included in the study. Age, gender, etiology, site and type of fracture, associated injuries, mode of treatment, outcome, complications, and follow up were evaluated. The cases were divided into 3 age groups: Group A: 1.5-5 years, Group B: 6-11 years, and Group C: 12-16 years. Sixty one patients were included in the study. The male to female ratio was 2:1. Motor vehicle accident was the most common cause. Associated trauma was more common in young children. The condyle was involved in 54% of the fractures. Closed reduction and intermaxillary fixation was the most common treatment used. Complications were rare. Management of mandibular fracture in the pediatric age group is a challenge. The anatomical complexity of the developing mandible and teeth strongly suggest the use of surgical techniques that are different from those routinely used in adults. The conservative approach is recommended. Whenever possible closed reduction should be the treatment of choice. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

Abstract Objective To provide primary care physicians with a novel approach to risk identification and related clinical decision making in the management of undifferentiated mental disorders. Sources of information We conducted a review of the literature in PubMed, CINAHL, PsycINFO, and Google Scholar using the search terms diagnostic uncertainty, diagnosis, risk identification, risk assessment/methods, risk, risk factors, risk management/methods, cognitive biases and psychiatry, decision making, mental disorders/diagnosis, clinical competence, evidence-based medicine, interviews as topic, psychiatry/education, psychiatry/methods, documentation/methods, forensic psychiatry/education, forensic psychiatry/methods, mental disorders/classification, mental disorders/psychology, violence/prevention and control, and violence/psychology. Main message Mental disorders are a large component of practice in primary care and often present in an undifferentiated manner, remaining so for prolonged periods. The challenging search for a diagnosis can divert attention from risk identification, as diagnosis is commonly presumed to be necessary before treatment can begin. This might inadvertently contribute to preventable adverse events. Focusing on salient aspects of the patient presentation related to risk should be prioritized. This article presents a novel approach to organizing patient information to assist risk identification and decision making in the management of patients with undifferentiated mental disorders. Conclusion A structured approach can help physicians to manage the clinical uncertainty common to risk identification in patients with mental disorders and cope with the common anxiety and cognitive biases that affect priorities in risk-related decision making. By focusing on risk, functional impairments, and related symptoms using a novel framework, physicians can meet their patients’ immediate needs while continuing the search for diagnostic clarity and long-term treatment.

Surrogate markers for time-varying treatments and outcomes
Hsu, Jesse Y; Kennedy, Edward H; Roy, Jason A; Stephens-Shields, Alisa J; Small, Dylan S; Joffe, Marshall M
2015-01-01
Background A surrogate marker is a variable commonly used in clinical trials to guide treatment decisions when the outcome of ultimate interest is not available. A good surrogate marker is one where the treatment effect on the surrogate is a strong predictor of the effect of treatment on the outcome. We review the situation when there is one treatment delivered at baseline, one surrogate measured at one later time point and one ultimate outcome of interest, and discuss new issues arising when variables are time-varying. Methods Most of the literature on surrogate markers has only considered simple settings with one treatment, one surrogate, and one outcome of interest at a fixed time point. However, more complicated time-varying settings are common in practice. In this paper, we describe the unique challenges in two settings, time-varying treatments and time-varying surrogates, while relating the ideas back to the causal-effects and causal-association paradigms. Conclusions In addition to discussing and extending popular notions of surrogacy to time-varying settings, we give examples illustrating that one can be misled by not taking into account time-varying information about the surrogate or treatment. We hope this paper has provided some motivation for future work on estimation and inference in such settings. PMID:25948621

Background Anxiety disorders are common, and cognitive–behavioural therapy (CBT) is a first-line treatment. Candidate gene studies have suggested a genetic basis to treatment response, but findings have been inconsistent. Aims To perform the first genome-wide association study (GWAS) of psychological treatment response in children with anxiety disorders (n = 980). Method Presence and severity of anxiety was assessed using semi-structured interview at baseline, on completion of treatment (post-treatment), and 3 to 12 months after treatment completion (follow-up). DNA was genotyped using the Illumina Human Core Exome-12v1.0 array. Linear mixed models were used to test associations between genetic variants and response (change in symptom severity) immediately post-treatment and at 6-month follow-up. Results No variants passed a genome-wide significance threshold (P = 5 × 10−8) in either analysis. Four variants met criteria for suggestive significance (P<5 × 10−6) in association with response post-treatment, and three variants in the 6-month follow-up analysis. Conclusions This is the first genome-wide therapygenetic study. It suggests no common variants of very high effect underlie response to CBT. Future investigations should maximise power to detect single-variant and polygenic effects by using larger, more homogeneous cohorts. PMID:26989097
Comparison between Ultroid and rubber band ligation in treatment of internal hemorrhoids.

2010-01-01
Hemorrhoid is one of the most common surgical diseases and different methods are available for its treatment. This study is a comparison between two methods of treatment of internal hemorrhoid, Monopolar low voltage instrument (Ultroid) and Rubber Band Ligation. This method has been carried out prospectively in which 50 patients who were treated with rubber band ligation and 50 patients with Ultroid were compared according to the incidence of complications, post-operative pain and treatment response. According to this study complete success rate with Ultroid was 82% and partial success rate was 10% and no response to treatment was seen in 8%. In Rubber Band method the complete response rate was 94% (P=0.2). With Ultroid, 74% of patient reported no postoperative pain, 24% reported mild and moderate pain and 2% of patients complained of severe pain. With Rubber band ligation, 72% of patients reported no post-operative pain, 26% reported mild and moderate pain and 1% complained of severe pain (P=0.00). Rubber Band ligation and Ultroid are both considered as outpatient procedures for treatment of hemorrhoids. Both methods are mostly used for grade 1, 2 and sometime grade 3 hemorrhoids. In Ultroid method the operator is required to hold the probe for a period of time, and in most cases, the surgeon should spend between 20-25 minutes for the coagulation of three piles. Some surgeons do not have patience for this modality of internal hemorrhoid treatment. In this study we achieved acceptable results comparable with those of other techniques.

Background and Aims Aluminium (Al) resistance in common bean is known to be due to exudation of citrate from the root after a lag phase, indicating the induction of gene transcription and protein synthesis. The aims of this study were to identify Al-induced differentially expressed genes and to analyse the expression of candidate genes conferring Al resistance in bean. Methods The suppression subtractive hybridization (SSH) method was used to identify differentially expressed genes in an Al-resistant bean genotype (‘Quimbaya’) during the induction period. Using quantitative real-time PCR the expression patterns of selected genes were compared between an Al-resistant and an Al-sensitive genotype (‘VAX 1’) treated with Al for up to 24 h. Key Results Short-term Al treatment resulted in up-regulation of stress-induced genes and down-regulation of genes involved in metabolism. However, the expressions of genes encoding enzymes involved in citrate metabolism were not significantly affected by Al. Al treatment dramatically increased the expression of common bean expressed sequence tags belonging to the citrate transporter gene family MATE (multidrug and toxin extrusion family protein) in both the Al-resistant and -sensitive genotype in close agreement with Al-induced citrate exudation. Conclusions The expression of a citrate transporter MATE gene is crucial for citrate exudation in common bean. However, although the expression of the citrate transporter is a prerequisite for citrate exudation, genotypic Al resistance in common bean particularly depends on the capacity to sustain the synthesis of citrate for maintaining the cytosolic citrate pool that enables exudation.

The energy-dependent probability density of tunneled carrier states for arbitrarily specified longitudinal potential-energy profiles in planar bipolar devices is numerically computed using the scattering method. Results agree accurately with a previous treatment based on solution of the localized eigenvalue problem, where computation times are much greater. These developments enable quantitative treatment of tunneling-assisted recombination in irradiated heterojunction bipolar transistors, where band offsets may enhance the tunneling effect by orders of magnitude. The calculations also reveal the density of non-tunneled carrier states in spatially varying potentials, and thereby test the common approximation of uniform- bulk values for such densities.

Background Benign liver lesions are common incidental radiologic findings. Methods Experts convened in 2011 at a Society for Surgery of the Alimentary Tract/ Americas Hepato-Pancreato-Biliary Association joint symposium to discuss the evaluation and treatment of benign liver lesions. Results Most benign liver lesions can be accurately diagnosed with high-quality imaging, including ultrasonography, multiphase computed tomography, and magnetic resonance imaging, particularly with hepatocyte-specific contrast agents. Percutaneous biopsy is reserved for lesions that cannot be characterized radiographically, and its accuracy is improved with immunophenotypic markers. Hepatic cysts are the most commonly diagnosed benign liver lesions; these must be distinguished from malignant cystic lesions, which are rare. Among the solid benign liver lesions, hemangiomas and focal nodular hyperplasia seldom require treatment. In contrast, hepatocellular adenomas are associated with a risk for complications. A new classification system for hepatocellular adenomas based on genetic and phenotypic features can help guide patient care. In patients who are symptomatic or at risk for complications, multidisciplinary evaluation and treatment based on clinicopathologic, radiographic, and molecular analysis is needed. Conclusions Most benign liver lesions can be accurately diagnosed radiographically and do not require treatment. Treatment is necessary for patients with symptoms or at risk for complications.

[Sachse internal urethrotomy: endoscopic treatment of urethral strictures].
Pfalzgraf, D; Häcker, A
2013-05-01
The most commonly used treatment modality for urethral strictures is the direct visual internal urethrotomy (DVUI) method according to Sachse. It is an effective short-term treatment, but the long-term success rate is low. A number of factors influence the outcome of DVUI including stricture location, spongiofibrosis and previous endoscopic stricture treatment. Multiple urethrotomy has a negative impact on the success rate of subsequent urethroplasty. A thorough preoperative diagnostic work-up including combined retrograde urethrogram/voiding cystourethrogram (RUG/VCUG) and urethrocystoscopy is, therefore, mandatory to allow for patient counselling regarding the risk of stricture recurrence and other treatment options. After a failed primary DVUI, subsequent urethrotomy cannot be expected to be curative.
Multivariate Analysis of Longitudinal Rates of Change
Bryan, Matthew; Heagerty, Patrick J.
2016-01-01
Longitudinal data allow direct comparison of the change in patient outcomes associated with treatment or exposure. Frequently, several longitudinal measures are collected that either reflect a common underlying health status, or characterize processes that are influenced in a similar way by covariates such as exposure or demographic characteristics. Statistical methods that can combine multivariate response variables into common measures of covariate effects have been proposed by Roy and Lin [1]; Proust-Lima, Letenneur and Jacqmin-Gadda [2]; and Gray and Brookmeyer [3] among others. Current methods for characterizing the relationship between covariates and the rate of change in multivariate outcomes are limited to select models. For example, Gray and Brookmeyer [3] introduce an “accelerated time” method which assumes that covariates rescale time in longitudinal models for disease progression. In this manuscript we detail an alternative multivariate model formulation that directly structures longitudinal rates of change, and that permits a common covariate effect across multiple outcomes. We detail maximum likelihood estimation for a multivariate longitudinal mixed model. We show via asymptotic calculations the potential gain in power that may be achieved with a common analysis of multiple outcomes. We apply the proposed methods to the analysis of a trivariate outcome for infant growth and compare rates of change for HIV infected and uninfected infants. PMID:27417129

We report our initial experience using the Amplatzer Vascular Plug II (AVP2) in the treatment of a left common iliac aneurysm. Following investigation by computerized tomographic angiography and catheter angiography, a 79-year-old man was found to have a markedly tortuous iliac system, with a left common iliac artery aneurysm that measured 48 mm in maximal diameter. Due to the patient's age and comorbidities the surgical opinion was that conventional open repair was not suitable. However, due to the tortuous nature of the aneurysm and iliac vessels, standard endovascular repair, using either a bifurcated or an aorto-uni-iliac stent graft, was alsomore » not possible. A combined approach was used by embolizing the ipsilateral internal iliac artery using coils and excluding the aneurysm using two AVP2 occlusion devices, followed by femorofemoral crossover grafting. Total aneurysm occlusion was achieved using this method and this allowed the patient to have a much less invasive surgical procedure than with conventional open repair of common iliac aneurysms, thus avoiding potential comorbidity and mortality.« less
Beyond gastric adenocarcinoma: Multimodality assessment of common and uncommon gastric neoplasms
Richman, Danielle M.; Tirumani, Sree Harsha; Hornick, Jason L.; Fuchs, Charles S.; Howard, Stephanie; Krajewski, Katherine; Ramaiya, Nikhil; Rosenthal, Michael
2016-01-01
Despite advances in molecular biology, imaging, and treatment, gastric neoplasms remain a significant cause of morbidity and mortality; gastric adenocarcinoma is the fifth most common malignancy and third most common cause of death worldwide (Brenner et al., Methods Mol Biol 472:467–477, 2009; Howson et al. Epidemiol Rev 8:1–27, 1986; Roder, Gastric Cancer 5(Suppl 1):5–11, 2002; Ferlay et al., GLOBOCAN 2012 v1.0, Cancer Incidence and Mortality Worldwide: IARC CancerBase No. 11 [Internet]. International Agency for Research on Cancer, 2013). Because of both the frequency at which malignant gastric tumors occur as well as the worldwide impact, gastric neoplasms remain important lesions to identify and characterize on all imaging modalities. Despite the varied histologies and behaviors of these neoplasms, many have similar imaging features. Nonetheless, the treatment, management, and prognosis of gastric neoplasms vary by pathology, so it is essential for the radiologist to make every effort to differentiate between these lesions and raise the less common entities as differential diagnostic considerations when appropriate.

The aim of this study was to compare the three different treatment methods and investigate The effectiveness of the therapeutic effect of common salt. This retrospective study involved patients who were treated in our clinic for umbilical pilonidal sinus disease between January 2010 and December 2011. The patients were divided to three subgroups according to treatment methods. Group I: Cases treated with only local debridement and systemic antibiotic, group II: cases treated with local debridement, systemic antibiotic and silver nitrate, group 3: cases treated with debridement, systemic antibiotic and salt. In this study, 63 patients with the diagnosis of UPS were treated in our clinic. The patients were classified into three groups; group I included 20 patients, group II included 18 patients and group III included 18 patients. During 16-24 months of follow-up, 4 (20%) recurrences in group1 and 2 (11.1%) recurrences in group 2 were detected. Recurrence rate of group 3 was significantly different (5.55%) when compared to group 2. The mean period for returning to daily activities and work was 1 day for the patients. In conclusion, we suggest that pilonidal sinus cases which are not complicated by abcess and cellulitis can be treated by local removal of umbilical hairs, debridement and dressing without surgery. We conclude that application of common salt (table/ cooking salt) to umbilical pilonidal sinus with granuloma is a simple and highly effective way of treatment without any relapse and complications. Conservative treatment, Local debridement, Umblical pilonidal sinus.

In the European Union, unaccompanied asylum seekers below 18 years of age are entitled to specific treatment. Age assessment practices to verify the age-statement by the asylum seeker differ between EU Member States. Medical methods in use raise questions about accuracy, reliability and safety. The medical, legal and ethical acceptability of invasive methods (notably X-rays) in particular is controversial. Human rights are at stake. The lack of common practices results in different levels of protection (discrimination). The absence ofstandardisation is an obstacle for the functioning of the Common European Asylum System. EU Best Practice Guidelines should remedy the situation; such guidelines should reflect the best interest of the child.
Is Exercise a Viable Treatment for Depression?
Blumenthal, James A.; Smith, Patrick J.; Hoffman, Benson M.
2013-01-01
Depression is a common disorder that is associated with compromised quality of life, increased health care costs, and greater risk for a variety of medical conditions, particularly coronary heart disease. This review examines methods for assessing depression and discusses current treatment approaches. Traditional treatments include psychotherapy and antidepressant medications, but such treatments are not effective for all patients and alternative approaches have recently received increased attention, especially the use of aerobic exercise. This review examines evidence that exercise is effective in improving depressive symptoms among patients with major depression and offers practical suggestions for helping patients initiate and maintain exercise in their daily lives.

OBJECTIVES: Primary hyperhidrosis usually affects the hands, armpits, feet and cranio-facial region. Sweating in other areas is common in secondary hyperhidrosis (after surgery or in specific clinical conditions). Oxybutynin has provided good results and is an alternative for treating hyperhidrosis at common sites. Our aim was to evaluate the efficacy of oxybutynin as a treatment for primary sweating at uncommon sites (e.g., the back and groin). METHODS: This retrospective study analyzed 20 patients (10 females) who received oxybutynin for primary focal hyperhidrosis at uncommon sites. The subjects were evaluated to determine quality of life before beginning oxybutynin and six weeks afterward and they were assigned grades (on a scale from 0 to 10) to measure their improvement at each site of excessive sweating after six weeks and at the last consult. RESULTS: The median follow-up time with oxybutynin was 385 days (133-1526 days). The most common sites were the back (n = 7) and groin (n = 5). After six weeks, the quality of life improved in 85% of the subjects. Dry mouth was very common and was reported by 16 patients, 12 of whom reported moderate/severe dry mouth. Five patients stopped treatment (two: unbearable dry mouth, two: excessive somnolence and one: palpitations). At the last visit, 80% of patients presented with moderate/great improvement at the main sites of sweating. CONCLUSION: After six weeks, more than 80% of the patients presented with improvements in their overall quality of life and at the most important site of sweating. Side effects were common (80% reported at least one side effect) and caused 25% of the patients to discontinue treatment. Oxybutynin is effective for treating bothersome hyperhidrosis, even at atypical locations and most patients cope well with the side effects. PMID:25318092

Treatment adherence is of critical importance in the management of patients with IBD. Poor adherence can lead to increased disease activity, loss of response to therapy, and increased costs of care. It has been well established that adherence to long-term therapy for chronic illnesses is extremely poor, averaging around 50% in developed countries. Measured rates of nonadherence in IBD are similar, but vary depending on the type of therapy and the population being observed. This article reviews the scientific data on treatment nonadherence in IBD. The methods commonly used to evaluate treatment adherence investigation are reviewed. The consequences and scope of treatment nonadherence are summarized. Finally, the scientific data on management strategies to address the problem of treatment nonadherence are explored.

The aim of the European Funded Project BRAFO (benefit-risk analysis of foods) project was to develop a framework that allows quantitative comparison of human health risks and benefits of foods based on a common scale of measurement. This publication describes the application of the BRAFO methodology to three different case studies: the formation of acrylamide in potato and cereal based products, the formation of benzo(a)pyrene through smoking and grilling of meat and fish and the heat-treatment of milk. Reference, alternative scenario and target population represented the basic structure to test the tiers of the framework. Various intervention methods intended to reduce acrylamide in potato and cereal products were evaluated against the historical production methods. In conclusion the benefits of the acrylamide-reducing measures were considered prevailing. For benzo(a)pyrene, three illustrated alternative scenarios were evaluated against the most common smoking practice. The alternative scenarios were assessed as delivering benefits, introducing only minimal potential risks. Similar considerations were made for heat treatment of milk where the comparison of the microbiological effects of heat treatment, physico-chemical changes of milk constituents with positive and negative health effects was assessed. In general, based on data available, benefits of the heat treatment were outweighing any risks. Copyright © 2012 ILSI Europe. Published by Elsevier Ltd.. All rights reserved.

Mandibulo-maxillary fixation (MMF) is indispensable for mandibular fracture treatment. Various means for MMF have been proposed, of which arch bars are widely considered to be the mainstay. However, disadvantages to this method have initiated a quest for an alternative, leading to the introduction of MMF screws. MMF screws have frequently been criticized for poor stability of fracture sites, root damage, hardware failure, and nerve damage. We retrospectively evaluate the FAMI (Fixation and Adaptation in Mandibular Injuries) screw in mandibular fracture treatment by scanning for clinically and radiologically visible complications. In total, 534 FAMI screws were used in the successful treatment of 96 males and 34 females. Condylar fractures were most commonly encountered, representing 120 of 241 fracture sites. 15 general fracture-related complications occurred, with the most common being nerve function impairment (3.8%) and postoperative malocclusion (4.6%). In nine cases (7%), clinically visible FAMI-screw-related complications occurred, with the most prevalent being screw loosening (2.3%) and mucosal signs of inflammation (3.1%). Duration of FAMI screws was associated with the occurrence of clinically visible complications (p = 0.042). Radiologically, clinically invisible dental hard tissue damage was noted in 21 individuals (16%). Therefore, FAMI screws seem to be a reliable and safe method for mandibulo-maxillary fixation.

Immunofluorescence is a common method used to visualize subcellular compartments and to determine the localization of specific proteins within a tissue sample. A great hindrance to the acquisition of high quality immunofluorescence images is endogenous autofluorescence of the tissue caused by aging pigments such as lipofuscin or by common sample preparation processes such as aldehyde fixation. This protocol describes how background fluorescence can be greatly reduced through photobleaching using white phosphor light emitting diode (LED) arrays prior to treatment with fluorescent probes. The broad-spectrum emission of white phosphor LEDs allow for bleaching of fluorophores across a range of emission peaks. The photobleaching apparatus can be constructed from off-the-shelf components at very low cost and offers an accessible alternative to commercially available chemical quenchers. A photobleaching pre-treatment of the tissue followed by conventional immunofluorescence staining generates images free of background autofluorescence. Compared to established chemical quenchers which reduced probe as well as background signals, photobleaching treatment had no effect on probe fluorescence intensity while it effectively reduced background and lipofuscin fluorescence. Although photobleaching requires more time for pre-treatment, higher intensity LED arrays may be used to reduce photobleaching time. This simple method can potentially be applied to a variety of tissues, particularly postmitotic tissues that accumulate lipofuscin such as the brain and cardiac or skeletal muscles.

Vulvovaginal candidiasis is one of the most common mycosis. However, the information about antifungal susceptibilities of the yeasts causing this infection is scant. We studied 121 yeasts isolated from 118 patients with vulvovaginal candidiasis. The isolates were identified by phenotypic and molecular methods, including four phenotypic methods described to differentiate Candida albicans from C. dubliniensis. Antifungal susceptibility testing was performed according to CLSI documents M27A3 and M27S4 using the drugs available as treatment option in the hospital. Diabetes, any antibacterial and amoxicillin treatment were statistically linked with vulvovaginal candidiasis, while oral contraceptives were not considered a risk factor. Previous azole-based over-the-counter antifungal treatment was statistically associated with non-C.albicans yeasts infections. The most common isolated yeast species was C. albicans (85.2 %) followed by C. glabrata (5 %), Saccharomyces cerevisiae (3.3 %), and C. dubliniensis (2.5 %). Fluconazole- and itraconazole-reduced susceptibility was observed in ten and in only one C. albicans strains, respectively. All the C. glabrata isolates showed low fluconazole MICs. Clotrimazole showed excellent potency against all but seven isolates (three C. glabrata, two S. cerevisiae, one C. albicans and one Picchia anomala). Any of the strains showed nystatin reduced susceptibility. On the other hand, terbinafine was the less potent drug. Antifungal resistance is still a rare phenomenon supporting the use of azole antifungals as empirical treatment of vulvovaginal candidiasis.

To compare procedure time, complications, mortality, and short-term outcome in dogs with patent ductus arteriosus (PDA) treated by surgical ligation (SL) or transarterial coil occlusion (TCO). Retrospective study. Dogs with PDA (n=204). Medical records of dogs treated for PDA were reviewed. Dogs treated by SL when it was the primary method used for PDA treatment (1993-1998) were compared with dogs treated by TCO when it was the primary method used for PDA treatment (1999-2003). Dogs treated during the transition between techniques, dogs treated with SL (1999-2003) and dogs treated with TCO before 1999, as well as dogs with pulmonary hypertension, or bidirectional or reversed (right-to-left) flow through the PDA were excluded from analysis. Age, weight, gender distribution, and procedure times (P=.43) were similar for both groups. Major complications were more common with SL (12% versus 4.3%; P=.035) whereas minor complications were more common with TCO (12% versus 26%; P=.015). Initial success rate was higher for SL (94%) compared with TCO (84%; P=.027). There was no significant difference in mortality between SL (5.6%) and TCO (2.6%; P=.27). Both SL and TCO are acceptable PDA treatments with comparable mortality; however, SL was associated with a higher risk of major complications and TCO was associated with a lower initial success rate.
A hybrid method in combining treatment effects from matched and unmatched studies.

The most common data structures in the biomedical studies have been matched or unmatched designs. Data structures resulting from a hybrid of the two may create challenges for statistical inferences. The question may arise whether to use parametric or nonparametric methods on the hybrid data structure. The Early Treatment for Retinopathy of Prematurity study was a multicenter clinical trial sponsored by the National Eye Institute. The design produced data requiring a statistical method of a hybrid nature. An infant in this multicenter randomized clinical trial had high-risk prethreshold retinopathy of prematurity that was eligible for treatment in one or both eyes at entry into the trial. During follow-up, recognition visual acuity was accessed for both eyes. Data from both eyes (matched) and from only one eye (unmatched) were eligible to be used in the trial. The new hybrid nonparametric method is a meta-analysis based on combining the Hodges-Lehmann estimates of treatment effects from the Wilcoxon signed rank and rank sum tests. To compare the new method, we used the classic meta-analysis with the t-test method to combine estimates of treatment effects from the paired and two sample t-tests. We used simulations to calculate the empirical size and power of the test statistics, as well as the bias, mean square and confidence interval width of the corresponding estimators. The proposed method provides an effective tool to evaluate data from clinical trials and similar comparative studies. Copyright © 2013 John Wiley & Sons, Ltd.

Background This study updated our knowledge of UK primary care neuropathic pain incidence rates and prescribing practices. Methods Patients with a first diagnosis of post-herpetic neuralgia (PHN), painful diabetic neuropathy (PDN) or phantom limb pain (PLP) were identified from the General Practice Research Database (2006 – 2010) and incidence rates were calculated. Prescription records were searched for pain treatments from diagnosis of these conditions and the duration and daily dose estimated for first-line and subsequent treatment regimens. Recording of neuropathic back and post-operative pain was investigated. Results The study included 5,920 patients with PHN, 5,340 with PDN, and 185 with PLP. The incidence per 10,000 person-years was 3.4 (95% CI 3.4, 3.5) for PHN; and 0.11 (95% CI 0.09, 0.12) for PLP. Validation of the PDN case definition suggested that was not sensitive. Incident PHN increased over the study period. The most common first-line treatments were amitriptyline or gabapentin in the PDN and PLP cohorts, and amitriptyline or co-codamol (codeine-paracetamol) in PHN. Paracetamol, co-dydramol (paracetamol-dihydrocodeine) and capsaicin were also often prescribed in one or more condition. Most first-line treatments comprised only one therapeutic class. Use of antiepileptics licensed for neuropathic pain treatment had increased since 2002–2005. Amitriptyline was the only antidepressant prescribed commonly as a first-line treatment. Conclusion The UK incidence of diagnosed PHN has increased with the incidence of back-pain and post-operative pain unclear. While use of licenced antiepileptics increased, prescribing of therapy with little evidence of efficacy in neuropathic pain is still common and consequently treatment was often not in-line with current guidance.

Background Infantile purulent meningitis (PM) is a commonly severe intracranial infectious disease in infants under age 1 year. In recent years, several diagnostic and treatment methods were reported, but in these cases the neurological complications and sequel were often observed, among which subdural effusion (SE) is the most common complication in PM. Timely diagnosis and early intervention are vital for better outcomes. In this study, the surgical treatments for infantile PM complicated by SE were investigated. Material/Methods Patients who had PM complicated by SE in the Children’s Hospital of Hebei Province from June 2000 to June 2012 were retrospectively analyzed and 170 patients were enrolled in the study. Surgical treatment for each patient was adopted according to producing effusion time, leucocyte count, protein content, intracranial pressure, and bacteria culture, coupled with cranial ultrasound examination, CT, and MRI scans. Results Nearly, 15 patients were cured using serial taps, with a 50% cure rate. Seventeen out of 30 (56.6%) patients receiving subcutaneous reservoir drainage had better outcome. Nearly 80% of patients (55/69) who underwent minimally invasive trepanation and drainage were positive. Surgical procedure of minimally invasive trepanation and drainage combined with drug douche was effective in 63% of patients (19/30). In addition, 6 patients were cured with subdural-peritoneal shunt. Only 1 patient died, after the recurrence of meningitis, and the remaining 4 patients were cured by craniotomy. Conclusions For infantile PM complicated with SE, treatment needs be chosen according to the specific situation. Surgical procedure of minimally invasive trepanation and drainage is a very effective treatment in curing PM complicated by SE. The treatment was highly effective with the use of drug douche. Subdural-peritoneal shunt and craniotomy were as effective as in refractory cases. PMID:26482715
Pharmacists' perspectives on monitoring adherence to treatment in Cystic Fibrosis.

Cystic Fibrosis (CF) management requires complex treatment regimens but adherence to treatment is poor and has negative health implications. There are various methods of measuring adherence, but little is known regarding the extent of adherence measurement in CF centres throughout the UK and Ireland. To determine the adherence monitoring practices in CF centres throughout the UK and Ireland, and to establish CF pharmacists' views on these practices. UK and Ireland Cystic Fibrosis Pharmacists' Group's annual meeting (2014). A questionnaire was designed, piloted and distributed to pharmacists attending the UK and Ireland Cystic Fibrosis Pharmacists' Group's annual meeting (2014). The main outcome measures were the methods of inhaled/nebulised antibiotic supply and the methods used to measure treatment adherence in CF centres. The questionnaire also ascertained the demographic information of participating pharmacists. Closed question responses were analysed using descriptive statistics. Open questions were analysed using content analysis. Twenty-one respondents (84 % response) were included in the analysis and were mostly from English centres (66.7 %). Detailed records of patients receiving their inhaled/nebulised antibiotics were lacking. Adherence was most commonly described to be measured at 'every clinic visit' (28.6 %) and 'occasionally' (28.6 %). Patient self-reported adherence was the most commonly used method of measuring adherence in practice (90.5 %). The availability of electronic adherence monitoring in CF centres did not guarantee its use. Pharmacists attributed an equal professional responsibility for adherence monitoring in CF to Consultants, Nurses and Pharmacists. Seventy-six percent of pharmacists felt that the current adherence monitoring practices within their own unit were inadequate and associated with the absence of sufficient specialist CF pharmacist involvement. Many suggested that greater specialist pharmacist involvement could facilitate improved adherence monitoring. Current adherence knowledge is largely based on self-report. Further work is required to establish the most appropriate method of adherence monitoring in CF centres, to improve the recording of adherence and to understand the impact of increased specialist pharmacist involvement on that adherence.
Glaucoma –state of the art and perspectives on treatment

2015-01-01
Glaucoma is a chronic optic neuropathy characterized by progressive damage to the optic nerve, death of retinal ganglion cells and ultimately visual field loss. It is one of the leading causes of irreversible loss of vision worldwide. The most important trigger of glaucomatous damage is elevated eye pressure, and the current standard approach in glaucoma therapy is reduction of intraocular pressure (IOP). However, despite the use of effective medications or surgical treatment leading to lowering of IOP, progression of glaucomatous changes and loss of vision among patients with glaucoma is common. Therefore, it is critical to prevent vision loss through additional treatment. To implement such treatment(s), it is imperative to identify pathophysiological changes in glaucoma and develop therapeutic methods taking into account neuroprotection. Currently, there is no method of neuroprotection with long-term proven effectiveness in the treatment of glaucoma. Among the most promising molecules shown to protect the retina and optic nerve are neurotrophic factors. Thus, the current focus is on the development of safe and non-invasive methods for the long-term elevation of the intraocular level of neurotrophins through advanced gene therapy and topical eye treatment and on the search for selective agonists of neurotrophin receptors affording more efficient neuroprotection.

Objective Common mental disorders like mood and anxiety disorders and somatoform disorders have high costs, yet under-treatment is still frequent. Many people with common mental disorders are employed, so the workplace is potentially a suitable context in which to provide early treatment. Our study investigates whether a change of setting (workplace versus standard care) improves access to treatment for common mental disorders. Methods Conditional latent profile analysis was applied to identify user profiles for work ability (WAI), clinical symptoms like depression (patient health questionnaire depression, PHQ-9), health-related quality of life (QoL, SF-12), and work-related stress (Maslach Burnout Inventory, irritation scale). Patients were recruited consecutively, via psychotherapeutic consultation in the workplace (n = 174) or psychotherapeutic consultation in outpatient care (n = 193). Results We identified four user profiles in our model: ‘severe’ (n = 99), ‘moderate I—low QoL’ (n = 88), ‘moderate II—low work ability’ (n = 83), and ‘at risk’ (n = 97). The ‘at risk’ profile encompassed individuals with reduced work ability (36.0, 34.73 to 37.37), only mild clinical symptoms (PHQ-9 5.7, 4.92 to 6.53), no signs of work-related stress and good quality of life. A higher proportion of the ‘at risk’ group than of the ‘severe’ group sought help via the psychotherapeutic consultation in the workplace (OR 0.287, P < 0.01); this effect remained after controlling for gender. Conclusions Offering secondary mental health care in the workplace is feasible and accepted by users. Offering treatment in the workplace as an alternative to standard outpatient settings is a viable strategy for improving access to treatment for common mental disorders. PMID:28056101

Context Clinical supervision is the principal method of training for psychotherapeutic practice, however there is virtually no research on supervision practice in community settings. Of particular interest is the role supervision might play in facilitating implementation of evidence-based (EB) care in routine care settings. Objective This study examines the format and functions of clinical supervision sessions in routine care, as well as the extent to which supervision addresses psychotherapeutic practice elements common to EB care for children with disruptive behavior problems, who represent the majority of patients served in publicly-funded routine care settings. Methods Supervisors (n=7) and supervisees (n=12) from four publicly-funded community-based child mental health clinics reported on 130 supervision sessions. Results Supervision sessions were primarily individual in-person meetings lasting one hour. The most common functions included case conceptualization and therapy interventions. Coverage of practice elements common to EB treatments was brief. Discussion Despite the fact that most children presenting to public mental health services are referred for disruptive behavior problems, supervision sessions are infrequently focused on practice elements consistent with EB treatments for this population. Supervision is a promising avenue through which training in EB practices could be supported to improve the quality of care for children in community-based “usual care” clinics. PMID:24761163

SU-F-T-423: Automating Treatment Planning for Cervical Cancer in Low- and Middle- Income Countries
DOE Office of Scientific and Technical Information (OSTI.GOV)
Kisling, K; Zhang, L; Yang, J
Purpose: To develop and test two independent algorithms that automatically create the photon treatment fields for a four-field box beam arrangement, a common treatment technique for cervical cancer in low- and middle-income countries. Methods: Two algorithms were developed and integrated into Eclipse using its Advanced Programming Interface:3D Method: We automatically segment bony anatomy on CT using an in-house multi-atlas contouring tool and project the structures into the beam’s-eye-view. We identify anatomical landmarks on the projections to define the field apertures. 2D Method: We generate DRRs for all four beams. An atlas of DRRs for six standard patients with corresponding fieldmore » apertures are deformably registered to the test patient DRRs. The set of deformed atlas apertures are fitted to an expected shape to define the final apertures. Both algorithms were tested on 39 patient CTs, and the resulting treatment fields were scored by a radiation oncologist. We also investigated the feasibility of using one algorithm as an independent check of the other algorithm. Results: 96% of the 3D-Method-generated fields and 79% of the 2D-method-generated fields were scored acceptable for treatment (“Per Protocol” or “Acceptable Variation”). The 3D Method generated more fields scored “Per Protocol” than the 2D Method (62% versus 17%). The 4% of the 3D-Method-generated fields that were scored “Unacceptable Deviation” were all due to an improper L5 vertebra contour resulting in an unacceptable superior jaw position. When these same patients were planned with the 2D method, the superior jaw was acceptable, suggesting that the 2D method can be used to independently check the 3D method. Conclusion: Our results show that our 3D Method is feasible for automatically generating cervical treatment fields. Furthermore, the 2D Method can serve as an automatic, independent check of the automatically-generated treatment fields. These algorithms will be implemented for fully automated cervical treatment planning.« less
Stress as a seizure precipitant: Identification, associated factors, and treatment options.
McKee, Heather R; Privitera, Michael D
2017-01-01
Stress is a common and important seizure precipitant reported by epilepsy patients. Studies to date have used different methodologies to identify relationships between epilepsy and stress. Several studies have identified anxiety, depression, and childhood trauma as being more common in patients with epilepsy who report stress as a seizure precipitant compared to patients with epilepsy who did not identify stress as a seizure precipitant. In one survey study it was found that a majority of patients with stress-triggered seizures had used some type of stress reduction method on their own and, of those who tried this, an even larger majority felt that these methods improved their seizures. Additionally, small to moderate sized prospective trials, including randomized clinical trials, using general stress reduction methods have shown promise in improving outcomes in patients with epilepsy, but results on seizure frequency have been inconsistent. Based on these studies, we recommend that when clinicians encounter patients who report stress as a seizure precipitant, these patients should be screened for a treatable mood disorder. Furthermore, although seizure reduction with stress reduction methods has not been proven in a randomized controlled trial, other important endpoints like quality of life were improved. Therefore, recommending stress reduction methods to patients with epilepsy appears to be a reasonable low risk adjunctive to standard treatments. The current review highlights the need for future research to help further clarify biological mechanisms of the stress-seizure relationship and emphasizes the need for larger randomized controlled trials to help develop evidence based treatment recommendations for our epilepsy patients.

Treatment of idiopathic clubfoot: an historical review.
Dobbs, M B; Morcuende, J A; Gurnett, C A; Ponseti, I V
2000-01-01
Idiopathic clubfoot, one of the most common problems in pediatric orthopaedics, is characterized by a complex three-dimensional deformity of the foot. The treatment of clubfoot is controversial and continues to be one of the biggest challenges in pediatric orthopaedics. This controversy is due in part to the difficulty in measuring and evaluating the effectiveness of different treatment methods. We believe the heart of the debate is a lack of understanding of the functional anatomy of the deformity, the biological response of young connective tissue to injury and repair, and their combined effect on the long-term treatment outcomes. The aim of this review is not only to assess the different methods of clubfoot treatment used over the years in light of an evolving understanding of the pathoanatomy of the deformity, but to also clarify factors that allow a safe, logical approach to clubfoot management. Further research will be needed to fully understand the pathogenesis of clubfoot, as well as the long-term results and quality of life for the treated foot.

Background/Purpose. Understanding the practices of pediatric rheumatologists in diagnosing and treating chronic nonbacterial osteomyelitis (CNO) can provide important information to guide the development of consensus treatment plans. The objectives of this study were to determine physicians' approaches to (1) diagnosing and monitoring CNO, (2) ordering a bone biopsy, and (3) making treatment decisions. Methods. A survey was distributed among members of the Childhood Arthritis and Rheumatology Research Alliance using a web-based questionnaire. Results. 121 of 277 (41%) attending physician members completed the survey. Plain radiographs (89%) were most commonly used followed by regional MRI (78%), bone scintigraphy (43%), and whole-body MRI (36%). The top three reasons for performing a biopsy were constitutional findings (66%), unifocal bone lesions (64%), and nocturnal bone pain (45%). Nearly all responders (95%) prescribed nonsteroidal anti-inflammatory drugs (NSAIDs) as initial therapy. For patients who failed NSAID treatment, methotrexate (67%), tumor necrosis factor inhibitors (65%), and bisphosphonates (46%) were the next most commonly used treatments. The presence of a spinal lesion increased the use of bisphosphonate treatment. Conclusion. The diagnostic approach and disease activity monitoring for CNO varied among surveyed physicians. Our survey findings provided important background for the development of consensus treatment plans for CNO. PMID:28167963

Considering that large variations exist amongst practitioners in lumbar disorder management and the significant costs that lumbar disorders incur, determining clinical practice patterns to provide preliminary data for standardization should be given higher priority. Lumbar spinal stenosis (LSS) is commonly treated using integrative non-surgical methods by Korean medicine doctors (KMDs) in Korea, and this is the first study to assess current Korean medicine practice trends for LSS. A survey on KMD diagnosis, treatment, prognosis and decision-making in LSS treatment was developed in a 3-step procedure of preliminary drafting, revision based on extramural expert opinion, and final editing. The survey was conducted at the internal conference of a spine-specialty Korean medicine hospital on January 25th, 2015. The response rate was high at 79.19% (n = 118/149). Participants replied that they treated 7.3 ± 6.8 LSS patients/day using a multimodal treatment method consisting of acupuncture, pharmacopuncture, herbal medicine, Chuna manipulation, and electroacupuncture. Acupuncture mainly used Ashi points and MSAT, and pharmacopuncture mainly Shinbaro solution. The most frequently prescribed herbal medicine was Chungpa-jun, and the most commonly applied Chuna techniques were sidelying lumbar extension dysfunction correction technique, and prone lumbosacral joint distraction method. Radiological findings were mainly referred to for diagnosis, and clinical symptoms, age, radiological findings, and medical history were regarded to be important for prognosis. Participants replied that 7.8 ± 3.3 weeks were required for 50% reduction in pain, and 16.1 ± 7.7 weeks for 80% reduction. These results suggest that KMDs in Korea combine a conventional approach to LSS and a Korean medicine approach to low back pain for integration of empirical- and evidence-based diagnosis and treatment. The findings may contribute in bridging the divide between evidence and clinical practice guidelines for Korean medicine treatment of LSS and real-world clinical practice in future research.

Stormwater contaminant loading estimates using event mean concentration (EMC), rainfall/runoff relationship calculations and computer modelling (Model of Urban Stormwater Infrastructure Conceptualisation--MUSIC) demonstrated high variability in common methods of water quality assessment. Predictions of metal, nutrient and total suspended solid loadings for three highly urbanised catchments in Sydney estuary, Australia, varied greatly within and amongst methods tested. EMC and rainfall/runoff relationship calculations produced similar estimates (within 1 SD) in a statistically significant number of trials; however, considerable variability within estimates (∼50 and ∼25 % relative standard deviation, respectively) questions the reliability of these methods. Likewise, upper and lower default inputs in a commonly used loading model (MUSIC) produced an extensive range of loading estimates (3.8-8.3 times above and 2.6-4.1 times below typical default inputs, respectively). Default and calibrated MUSIC simulations produced loading estimates that agreed with EMC and rainfall/runoff calculations in some trials (4-10 from 18); however, they were not frequent enough to statistically infer that these methods produced the same results. Great variance within and amongst mean annual loads estimated by common methods of water quality assessment has important ramifications for water quality managers requiring accurate estimates of the quantities and nature of contaminants requiring treatment.
Lateral ankle injury. Literature review and report of two cases.
Pollard, Henry; Sim, Patrick; McHardy, Andrew
2002-07-01
Injury to the ankle joint is the most common peripheral joint injury. The sports that most commonly produce high ankle injury rates in their participating athletes include: basketball, netball, and the various codes of football. To provide an up to date understanding of manual therapy relevant to lateral ligament injury of the ankle. A discussion of the types of ligament injury and common complicating factors that present with lateral ankle pain is presented along with a review of relevant anatomy, assessment and treatment. Also included is a discussion of the efficacy of manual therapy in the treatment of ankle sprain. A detailed knowledge of the anatomy of the ankle as well as the early recognition of factors that may delay the rate of healing are important considerations when developing a management plan for inversion sprains of the ankle. This area appears to be under-researched however it was found that movement therapy and its various forms appear to be the most efficient and most effective method of treating uncomplicated ankle injury. Future investigations should involve a study to determine the effect chiropractic treatment (manipulation) may have on the injured ankle.

Research on substance use and misuse in Lebanon is scarce and, when available, focuses on a specific substance or a limited segment of the population. The objective of this Rapid Situation Assessment (RAS) study was to survey the use of multiple substances in diverse segments of the Lebanese population. A multi-method and multi-sample survey was conducted to collect quantitative and qualitative data from the academic sector (high school and university students), substance users in treatment or under arrest (prison, detention), and non-institutionalized "street" users. Age of first use of substances started as early as 9 years in the youth sample. Moreover, 12% of the high school students reported smoking one or more packs of cigarettes per day and 9% of the university students met criteria for DSM-IV alcohol abuse. Cannabis represented the most commonly used illicit drug in both high school and university students, and tranquilizers were the most frequently misused medicinal substance. Heroin was responsible for 50% of the treatment admissions, followed by cocaine (20%), and alcohol (20%); heroin was also the most common substance of arrest. Recidivism was almost the rule for heroin users across all treatment settings. Unperceived need for treatment was the most common reason for not seeking treatment in non-institutionalized drug users (47.6%). Injecting drug use was a common behavior noted within substance using populations, in treatment and non-institutionalized (about 50% of them), with a high rate of needle sharing practices. About half of all patients in treatment had a history of police arrests, and about one-third of those in prison ever received prior treatment for substance use. The study points towards a growing trend for substance use problems in early adolescence that warrants close monitoring. Further investigation of these patterns is needed since the Lebanese population might have specific pathways of abuse. There is a need to bring together various health, legislative, and academic stakeholders for a continuous appraisal of data from substance abuse studies as evidenced by the recent, although slow, progress in the fields of legislation and treatment that follow such concerted efforts.

Background Most research has focused on recognition by GPs of the common mental disorders: depression and anxiety. However, less is known about the factors that determine whether patients with those disorders that are recognised receive any active treatment. Aim To investigate factors associated with receiving active treatment among consecutive attenders identified by GPs as having a common mental disorder. Setting Data were collected as part of a cluster randomised controlled trial in 30 general practices in the south of Bristol, UK, on the impact of mental health guidelines in primary care. Method We studied 439 consecutive general practice attenders aged 16–64 years who were given a diagnosis of depression, anxiety, or chronic mixed anxiety and depression by their GP. The main outcome measure was the provision of any active treatment, whether pharmacological or psychological, for these disorders. Patient, GP, and practice level data, including sociodemographic, clinical, and administrative data were explored as predictors in a logistic regression model. Huber White variance estimates were used to account for hierarchical clustering. Results Of those patients identified as having a common mental disorder by the GP, 54% were offered active treatment. Higher symptom score, as measured by the General Health Questionnaire (GHQ) (odds ratio [OR] = 1.09; 95% confidence interval [CI] = 1.06 to 1.13; P<0.001) and being male (OR = 1.54; 95% CI = 1.13 to 2.09; P = 0.006), were both associated with an increased likelihood of being offered active treatment. Patients with anxiety (OR = 0.24; 95% = CI 0.14 to 0.41; P<0.001), or chronic mixed anxiety/depression (OR = 0.41; 95% CI = 0.23 to 0.73; P = 0.003) were less likely to be offered active treatment than those considered to have depression. Conclusion When deciding to offer active treatment for common mental disorders, GPs appear to be influenced by the severity of symptoms rather than their ‘understandability’ in relation to recent life stresses or the social context of distress. Further research is needed to investigate why men are more likely and those with an anxiety disorder less likely, to be offered active treatment. PMID:16282000

Summary Objective As disparities in epilepsy treatment are not uncommon, we examined population-based estimate of initial anti-epileptic drugs (AEDs) in new-onset epilepsy among U.S. Medicare beneficiaries 65 years and older across racial/ethnic minorities. Methods We conducted retrospective analyses of 2008–2010 Medicare administrative claims for a 5% random sample of beneficiaries augmented for minority representation. New-onset epilepsy cases in 2009 had ≥1 ICD-9 345.x or ≥2 ICD-9 780.3x, and ≥1 AED, AND no seizure/epilepsy claim codes nor AEDs in preceding 365 days. We examined AED use and concordance with Quality Indicators of Epilepsy Treatment (QUIET) #6 (monotherapy as initial treatment= ≥30 day first prescription with no other concomitant AEDs), and prompt AED treatment (first AED within 30 days from diagnosis). Logistic regression examined likelihood of prompt treatment by demographics (race/ethnicity, gender, age), clinical (number of comorbid conditions, neurology care, index event occurring in the ER), and economic (part D coverage phase, eligibility for part D low income subsidy (LIS), and zip code level poverty) factors. Results Over one year follow-up, 79.6% of 3,706 new epilepsy cases had one AED only (77.89% of Whites vs. 89% of American Indian/Alaskan Native; AI/AN). Levetiracetam was the most commonly prescribed AED (45.5%: from 24.6% AI/AN to 55.0% Whites). The second most common was phenytoin (30.6%: from 18.8% Asians to 43.1% AI/AN). QUIET 6 concordance was 94.7% (93.9% for Whites to 97.3% of AI/AN). Only 50% received prompt AED therapy (49.6% whites to 53.9% AI/AN). Race/ethnicity was not significantly associated with AED patterns, monotherapy use, or prompt treatment. Conclusions Monotherapy is common across all racial/ethnic groups of older adults with new-onset epilepsy, older AEDs are commonly prescribed, and treatment is frequently delayed. Further studies on reasons for treatment delays are warranted. Interventions should be developed and tested to develop paradigms that lead to better care. PMID:28176298

2011-01-01
Objectives To identify the types and frequencies of pain treatments used by individuals with cerebral palsy (CP); examine the perceived effectiveness of these treatments; and identify the types of healthcare providers that were accessed for pain-related services. Design A cross-sectional survey design was employed. 83 adults (mean age=40.3 years, SD=13.6) with CP indicated their pain location and intensity during the past 3 months. Next, they indicated their use of 24 different pain treatments and the effectiveness of each. Finally, participants indicated the frequency of pain-related healthcare visits to specific providers over the past 6 months. Results 63% of participants reported experiencing chronic pain and rated their pain intensity over the past week as 5.1/10, on average. The most common pain locations were the lower back, hips, and legs. Physical interventions (e.g., physical therapy, strengthening) were the most common pain treatments reportedly used, and were rated as moderately effective. Many other treatments were also used, and participants sought pain-related care from a variety of providers. Conclusions Although participants reportedly accessed pain care from a variety of providers, and perceived that several types of treatments were effective, many of the treatments rated as effective were rarely used or provided. Future research using clinical trial methods would further elucidate the specific pain treatments that are most beneficial for adults with CP. PMID:21273894

The conservative and interventional treatment of fibroids.
Boosz, Alexander Stephan; Reimer, Peter; Matzko, Matthias; Römer, Thomas; Müller, Andreas
2014-12-22
Fibroids are the most common benign tumors in women. One-third of all women of reproductive age undergo treatment for symptomatic fibroids. In recent years, the spectrum of available treatments has been widened by the introduction of new drugs and interventional procedures. Selective literature review on the treatment of uterine fibroids, including consideration of several Cochrane Reviews. Fibroids can be treated with drugs, interventional procedures (uterine artery embolization [UAE] and focused ultrasound treatment [FUS]), and surgery. The evidence regarding the various available treatments is mixed. All methods improve symptoms, but only a few comparative studies have been performed. A meta-analysis revealed that recovery within 15 days is more common after laparoscopic enucleation than after open surgery (odds ratio [OR], 3.2). A minimally invasive hysterectomy, or one performed by the vaginal route, is associated with a shorter hospital stay and a more rapid recovery than open transabdominal hysterectomy. UAE is an alternative to hysterectomy for selected patients. The re-intervention rates after fibroid enucleation, hysterectomy, and UAE are 8.9-9%, 1.8-10.7%, and 7-34.6%, respectively. The main drugs used to treat fibroids are gonadotropin-releasing hormone analogs and selective progesterone receptor modulators. Multiple treatment options are available and enable individualized therapy for symptomatic fibroids. The most important considerations in the choice of treatment are the question of family planning and, in some cases, the technical limitations of the treatments themselves.
Epidemiology, Diagnosis, and Treatment of Scabies in a Dermatology Office.
Anderson, Kathryn L; Strowd, Lindsay C
Scabies is a neglected skin disease, and little is known about current incidence and treatment patterns in the United States. The purpose of this study was to examine demographic data, treatment types, success of treatment, and misdiagnosis rate of scabies in an outpatient dermatology clinic. A retrospective chart review of patients diagnosed with scabies within the past 5 years was performed. A total of 459 charts were identified, with 428 meeting inclusion criteria. Demographic data, diagnostic method, treatment choice, misdiagnosis rate, treatment failure, and itching after scabies are also reported. Children were the largest age group diagnosed with scabies, at 38%. Males (54%) were diagnosed with scabies more than females. The majority of diagnoses were made by visualizing ova, feces, or mites on light microscopy (58%). At the time of diagnosis, 45% of patients had been misdiagnosed by another provider. Topical permethrin was the most common treatment used (69%), followed by a combination of topical permethrin and oral ivermectin (23%), oral ivermectin (7%), and other treatments (1%). Our findings suggest that more accurate and faster diagnostic methods are needed to limit unnecessary treatment and expedite appropriate therapy for scabies. © Copyright 2017 by the American Board of Family Medicine.

Insomnia is one of the most common and wide-spread sleep disorders. It includes difficulties of sleep initiation, sustaining and daytime impairment. A condition of cerebral hyperarousal plays the most important role in the genesis of insomnia. Cognitive, electrophysiological and metabolic parameters are correlated with hyperarousal state. According to the International classification of sleep disorders (ICSD-3), insomnia is divided into acute, chronic and unclassified. Treatment of insomnia includes specific and nonspecific approaches. Regardless of the origin of insomnia, sleep hygiene and behavioral therapy remain the methods of choice for the treatment.
Stent-Assisted Endovascular Treatment of Anterior Communicating Artery Aneurysms – Literature Review
Kocur, Damian; Ślusarczyk, Wojciech; Przybyłko, Nikodem; Bażowski, Piotr; Właszczuk, Adam; Kwiek, Stanisław
2016-01-01
Summary The anterior cerebral artery is a common location of intracranial aneurysms. The standard coil embolization technique is limited by its inability to occlude wide-neck aneurysms. Stent deployment across the aneurysm neck supports the coil mass inside the aneurysmal sac, and furthermore, has an effect on local hemodynamic and biologic changes. In this article, various management strategies and techniques as well as angiographic outcomes and complications related to stent-assisted endovascular treatment of anterior communicating artery aneurysms are presented. This treatment method is safe and associated with low morbidity and mortality rates. PMID:27559426

Essential tremor, including the juvenile and senile variations, may be a result of a disorder of the servomechanism that controls physiologic tremor. Hands and arms are affected most commonly, and the tremor can vary in amplitude as well as frequency. Long-term treatment with propranolol has been helpful for some patients, although older patients are less likely to benefit. Other drugs and behaviour modification therapy have been less successful. Surgical treatment is effective but should probably be reserved for severe cases. An effective instrument for measuring the subjective and objective aspects of the tremor is still needed, as is an effective long-term method of treatment. PMID:7018658

Infantile feeding disorders (IFDs) are common causes of food refusal and failure to thrive, and are frequently encountered by primary care physicians and specialists. We have published the Wolfson criteria for IFD, which have eased the approach to the diagnosis of IFDs. Along with and complementary to the Wolfson criteria, we have also developed the role reversal treatment method for IFD, which has been briefly described earlier. The aim of this study was to validate the role reversal treatment method on a cohort of infants diagnosed as having IFD and to present a detailed description of this method for the first time. Parents of infants and children diagnosed as having IFD were invited to participate in the study; they were handed over a questionnaire comprising 6 categories of questions related to patient and parents behaviors, attitudes, and perceptions, which was completed at initiation and at the end of treatment. Full response was defined as improved normative feeding, cessation of abnormal parental feeding, and improved or normal growth patterns. A partial response was defined as success with two-third categories. We enrolled 38 patients, and 32 patients completed the study. Improved feeding occurred in 78%, full recovery was documented in 53% of infants by 6 months, and partial response was observed in another 25%. All forms of pathological feeding improved significantly (mechanistic, nocturnal, persecutory, forced feeding, and distraction). The role reversal treatment method is a simple and effective approach to the treatment of food refusal associated with IFD.

The aim of the study was to describe and compare (1) the types and prevalence of complementary and alternative medicine (CAM) treatments used among individuals with multiple sclerosis (MS) in the Nordic countries; (2) the types of conventional treatments besides disease-modifying medicine for MS that were used in combination with CAM treatments; (3) the types of symptoms/health issues addressed by use of CAM treatments. Methods. An internet-based questionnaire was used to collect data from 6455 members of the five Nordic MS societies. The response rates varied from 50.9% in Norway to 61.5% in Iceland. Results. A large range of CAM treatments were reported to be in use in all five Nordic countries. Supplements of vitamins and minerals, supplements of oils, special diet, acupuncture, and herbal medicine were among the CAM treatment modalities most commonly used. The prevalence of the overall use of CAM treatments within the last twelve months varied from 46.0% in Sweden to 58.9% in Iceland. CAM treatments were most often used in combination with conventional treatments. The conventional treatments that were most often combined with CAM treatment were prescription medication, physical therapy, and over-the-counter (OTC) medications. The proportion of CAM users who reported exclusive use of CAM (defined as use of no conventional treatments besides disease-modifying medicine for MS) varied from 9.5% in Finland to 18.4% in Norway. In all five Nordic countries, CAM treatments were most commonly used for nonspecific/preventative purposes such as strengthening the body in general, improving the body's muscle strength, and improving well-being. CAM treatments were less often used for the purpose of improving specific symptoms such as body pain, problems with balance, and fatigue/lack of energy. Conclusions. A large range of CAM treatments were used by individuals with MS in all Nordic countries. The most commonly reported rationale for CAM treatment use focused on improving the general state of health. The overall pattern of CAM treatment use was similar across the five countries. PMID:23304461

We explored attitudes about prevention, screening and treatment of hepatitis B virus (HBV) infection in Chinese, Korean and Vietnamese communities. We use qualitative methods in 12 focus groups (n = 113) of adults who self-reported their ethnicity to be Chinese, Korean, or Vietnamese. We use grounded theory (i.e., consensus-building between co-coders about recurring, emerging themes) for analysis. Diet, nutrition, fatigue and stress were misidentified as HBV causes. Improving hygiene, diet, exercise, and holistic methods were misidentified as viable HBV prevention methods. Common screening problems included not affording test and not understanding test results. Participants shared reasons for using complementary and alternative medicine--when Western medicine fails or becomes unaffordable. Participants sought information from medical providers and fellow community members, but also from the internet. Many of the attitudes and opinions that emerged may deter participation in HBV screening, prevention and treatment, insofar as community members may factor them into healthcare decision-making, choose alternative but ineffective methods of prevention and treatment, and undervalue the benefits of screening. More patient education in both traditional and new media is necessary for clarifying transmission, screening and treatment misunderstandings.

Cerebrovascular disease (CD) and metabolic syndrome (MetS) are two devastating health dilemma that continues to be a potential contributor to disability and mortality in human population all across the world. Scientific data clearly shows several mechanistic similarities between these two co-existing and interlinked conditions. The linkage exacerbates ongoing patho-physiological condition towards more lethal events. In view of the presence of modifiable risk factors in both CD and MetS, their management holds potential therapeutic value. Hence, developing common treatment strategies for these diseases could involve common molecular agents. In this communication, we have summarized some of the common pathological conditions viz. abdominal obesity, insulin resistance, dyslipidemia, hypertension, and endothelial dysfunction that further deteriorate existing homeostasis in CD and MetS. Based on our article, it is advocated that substantial improvements in novel multi-targeted drug discovery could provide the effective treatment methods in order to avoid the fatal complications related with CD and MetS.

Background There is little research documenting the post-treatment experiences and needs of oral/oropharyngeal cancer survivors. Methods In this cross-sectional study, 92 patients diagnosed with oral/oropharyngeal cancer diagnosed between 2 and 5 years prior completed a survey about oral cancer information and support needs. Results About half retrospectively reported that they did not receive a written treatment summary. The desire for more oral cancer information was common: One-third or more desired more information about long-term effects, recommended follow-up, and symptoms that should prompt contacting a doctor. Support needs were less common: Only a lack of energy was rated as a significant support need. Patients who had a recurrence, did not drink alcohol, and had a greater recurrence fear desired more information. Smokers and more distressed patients reported more support needs. Conclusions Survivors reported the desire for more oral cancer information. A desire for assistance was less common. PMID:26788714

The extremities are the most common anatomic location for gunshot wounds. Because of the prevalence of gunshot injuries, it is important that orthopaedic surgeons are knowledgeable about caring for them. The most common injuries seen with gunshot wounds are those of the soft tissues. Nonsurgical management of patients who have gunshot wounds with minimal soft-tissue disruption has been successfully accomplished in emergency departments for several years; this includes extremity wounds without nerve, intra-articular, or vascular injury. Stable, nonarticular fractures of an extremity have also been successfully treated with either minimal surgical or nonsurgical methods in the emergency department. Indications for surgical treatment include unstable fractures, intra-articular injuries, a significant soft-tissue injury (especially with skin loss), vascular injury, and/or a large or expanding hematoma.

Methicillin-resistant Staphylococcus aureus (MRSA) is a common pathogen in hospitals and the community. As the rapid spread and wide distribution of antimicrobial resistance (such as MRSA), treatment for infectious diseases caused by microorganisms has become a vital threat. Thus, early identification and genotyping are essential for further therapeutic treatment and the control of rapid expansion of MRSA. In combination with applications and data feedbacks, this review focused on the currently available molecular-based assays on their utility and performance for rapid typing of MRSA, especially on effective molecular-based methods. Besides, a common mobile element SCCmec and prevalence of HA-MRSA, LA-MRSA and CA-MRSA were introduced in this review in order to provide a more complete profile of MRSA.

The performances of the GC-MS determination of suspected allergens in fragrance concentrates have been investigated. The limit of quantification was experimentally determined (10 mg/L), and the variability was investigated for three different data treatment strategies: (1) two columns and three quantification ions; (2) two columns and one quantification ion; and (3) one column and three quantification ions. The first strategy best minimizes the risk of determination bias due to coelutions. This risk was evaluated by calculating the probability of coeluting a suspected allergen with perfume constituents exhibiting ions in common. For hydroxycitronellal, when using a two-column strategy, this may statistically occur more than once every 36 analyses for one ion or once every 144 analyses for three ions in common.

The epicondylitis humeri radialis (EHR) (tennis elbow), is a common disease in elbow joint pain syndromes. We treated patients with chronic pain for at least one year and no improvement with conservative or operative therapies with a new minimal invasive method, the EHR-Laser radiation (EHR- LR). With this method periepicondylar coagulations were applied to the trigger points of the patients. For this the previously established technique of facet joint coagulation with the Nd:Yag-laser was modified. In a follow-up study of between 6 weeks and 2 years all patients reported either a significant pain reduction or were symptom free. EHR-LR is a new method situated between conservative and surgical treatments for minimal invasive therapy of EHR. Several therapeutic rationales were discussed for the resulting pain reduction.

Introduction The current radiofrequency ablation technique requires invasive needle placement. On the other hand, most of the common photothermal therapeutic methods are limited by lack of accuracy of targeting. Gold and magnetic nanoparticles offer the potential to heat tumor tissue selectively at the cellular level by noninvasive interaction with laser and radiofrequency. Methods Gold nanospheres and gold-coated magnetic nanocomposites were used for inducing hyperthermia to treat subcutaneous Ehrlich carcinoma implanted in female mice. Results In mice treated with gold nanospheres, tumors continued to grow but at a slow rate. In contrast, more than 50% of the tumors treated with gold-coated magnetic nanocomposites completely disappeared. Conclusion This simple and noninvasive method shows great promise as a technique for selective magnetic photothermal treatment. PMID:22114479

2008-01-01
AIM: To evaluate the efficacy and safety of Heller myotomy (HM) for recurrent achalasia, performed after different methods of first-line treatment. METHODS: We searched for studies published in PubMed from 1966 to March 2008 on treatment of recurrent achalasia with HM after failure with different methods of first-line treatment. The efficacy of HM was assessed by a pooled estimate of response rate with individual studies weighted proportionally to sample size. RESULTS: Sixteen studies were eligible and included in the review. The results showed that HM has a better remission rate for recurrent achalasia after failure of HM [weighted mean (SD)] of 86.9% (21.8%) compared with 81.6% (23.8%) for pneumatic dilatation (PD). One study evaluated the efficacy of HM after failure of PD combined with botulinum toxin injection (83%). The most common complications were perforation and gastroesophageal reflux. CONCLUSION: HM has the best efficacy in patients with recurrent achalasia who were treated with HM as first-line treatment. Future studies should focus on how to increase the success rate and decrease the complications of HM. PMID:19084921

To identify (1) the predominant level of evidence of the clinical studies regarding the hip pathology, risk factors, treatment, and clinical outcomes in artistic athletes (dancers, figure skaters, and gymnasts) (2) the most commonly reported hip pathology, risk factors, treatments, and clinical outcomes in dancers, figure skaters, and gymnasts. To conduct this systematic review PubMed, EMBASE, and Scopus databases were searched for relevant studies and pertinent data were collected from the eligible articles. Included were studies which reported hip injuries in artistic athletes, the risk factors, treatment, and/or the clinical outcomes. We excluded case reports or irrelevant studies. No meta-analysis was performed because of study heterogeneity. The methodical index for nonrandomized studies (MINORS) criteria were used for quality control. Thirty-eight studies were included in the analysis. The mean MINORS score was 13.6 ± 4.6 points indicating fair quality of evidence of the included articles. The predominant level of evidence was level IV. Chondrolabral pathology and muscle injuries were the most commonly reported pathologies. We found only 2 risk factor analysis studies; however, many studies reported risk correlation between artistic sports or imaging findings and hip pathology. Treatment strategies were reported in only 7 studies, clinical outcomes are significantly underreported. Chondrolabral pathology was the most commonly reported hip pathology in artistic athletes, however, prospective cohort studies are necessary to really understand these injuries and their associated risk factors. The lack of clinical outcomes is significant and future data collection is required to assess the effectiveness of the various treatments.

Background Little is known about how Latinos with post-traumatic stress disorder (PTSD) understand their illness and their preferences for mental health treatment. Objective To understand the illness beliefs and treatment preferences of Latino immigrants with PTSD. Design Semi-structured, face-to-face interviews. Participants Sixty foreign-born, Latino adults recruited from five primary care centers in New York and New Jersey and screened for PTSD. Approach Content analytic methods identified common themes, their range, and most frequent or typical responses. Results Participants identified their primary feelings as sadness, anxiety, nervousness, and fear. The most common feeling was “sad” (triste). Other words frequently volunteered were “angry” (enojada), “nervous” (nerviosa), and “scared” (miedo). Participants viewed their PTSD as impairing health and functioning. They ascribed their somatic symptoms and their general medical problems to the “stress” from the trauma and its consequences on their lives. The most common reason participants volunteered for their work and school functioning being impaired was their poor concentration, often due to intrusive thoughts. Most expressed their desire to receive mental health treatment, to receive it within their primary care center, and preferred psychotherapy over psychotropic medications. Among participants who did not report wanting treatment, most said it was because the trauma was “in the past.” Conclusions Clinicians may consider enquiring about PTSD in Latino patients who report feeling sad, anxious, nervous, or fearful. Our study suggests topics clinicians may include in the psychoeducation of patients with PTSD. PMID:18587619

This study is to assess the Guidelines for Diagnosis and Treatment of Common Diseases of Otolaryngology in Traditional Chinese Medicine in clinical application and provide evidence for further guideline revision. The assessment was divided into applicability assessment and practicability assessment. The applicability assessment based on questionnaire survey and the traditional Chinese medicine (TCM) practitioners were asked to independently fill the Questionnaire for Applicability Assessment on the Guidelines for Diagnosis and Treatment in Traditional Chinese Medicine. The practicability assessment was based on prospective case investigation and analysis method and the TCM practitioners-in-charge filled the Case Investigation Questionnaire for Practicability Assessment on the Guidelines for Diagnosis and Treatment in Traditional Chinese Medicine. The data were analyzed in descriptive statistics. 151 questionnaires were investigated for applicability assessment and 1 016 patients were included for practicability assessment. The results showed that 88.74% of them were familiar with the guidelines and 45.70% used them. The guidelines quality and related items were similar in applicability assessment and practicability assessment, and scored highly as more than 85.00% except the "recuperating and prevention". The results suggested that the quality of Guidelines for Diagnosis and Treatment of Common Diseases of Otolaryngology in Traditional Chinese Medicine was high and could better guide the clinical practice. The "recuperating and prevention" part should be improved and the evidence data should be included in future guideline revision, so that the clinical utilization rate could be increased.

2014-01-01
Objective. To evaluate the prevalence of malocclusion and orthodontic treatment needs among 12- to 15-year-old schoolchildren in eastern Nepal and compare the findings with those of other populations. Methods. Two thousand seventy-four children (1149 males and 925 females) aged between 12 and 15 years were evaluated. Their orthodontic treatment need was assessed using the Index of Orthodontic Treatment Needs (IOTN) (dental health component (DHC)). Angle's classes of malocclusion were also evaluated. Results. The prevalence of classes I, II, and III was 48.50%, 32.68%, and 4.32%, respectively. The IOTN showed that 21.59% had an extreme treatment need, 24.67% had severe treatment need, 24.07% had moderate treatment need, 14.7% had mild treatment need, and 15.02% had no treatment need. Conclusion. Class I malocclusion is the most common, while class III is the least prevalent in eastern Nepal. The majority of the children need orthodontic treatment.

Objective This study was performed to identify the differences in clinical characteristics, operative methods, complications, and postoperative hospitalization stays for adults with esophageal foreign bodies with different durations of time from ingestion to effective treatment. Methods We retrospectively reviewed the medical records of 221 patients with a diagnosis of a foreign body in the esophagus, confirmed by rigid esophagoscopy, flexible esophagoscopy, or surgery. The differences between the two groups (Group A, ≤24 hours from ingestion to effective treatment; Group B, >24 hours from ingestion to effective treatment) were analyzed. Results Sharp foreign bodies comprised the majority of objects in the two groups, including jujube pits, bones (excluding fish bones), fish bones, dentures, and seafood shells. Foreign bodies located in the upper esophagus were more commonly observed in Group A than B. Significant differences were observed in the complication rate and length of postoperative hospitalization stays. Adults with esophageal foreign bodies had a high complication rate. Conclusions Rigid esophagoscopy can be used to remove sharp and bulky foreign bodies if more effective methods are unavailable. Effective treatment within 24 hours resulted in fewer complications and shorter postoperative hospitalization stays. PMID:28606025

Cervical cancer is the most common cancer of the female reproductive system up to 20% of malignant tumors of the female genital organs. Surgery is the main method in treatment for local cervical cancer but postoperative complications often are associated with dysfunction of the pelvic organs. Some researchers focus their attention on the preservation of the pelvic innervation without loss of surgery's radicalism, which is represented in this survey. The paper presents the results of comparative analysis of 54 cases of surgical treatment for invasive cervical cancer.
Surgical repair of an aberrant splenic artery aneurysm: report of a case.
Illuminati, Giulio; LaMuraglia, Glenn; Nigri, Giuseppe; Vietri, Francesco
2007-03-01
Aneurysms of the splenic artery are the most common splanchnic aneurysms. Aneurysms of a splenic artery with an anomalous origin from the superior mesenteric artery are however rare, with eight previously reported cases. Their indications for treatment are superposable to those of aneurysms affecting an orthotopic artery. Methods of treatment of this condition include endovascular, minimally invasive techniques and surgical resection. We report one more case of aneurysm of an aberrant splenic artery, treated with surgical resection, and preservation of the spleen.

Objective Although the majority of individuals with panic disorder first present to the primary care setting, little is known about the psychiatric treatment primary care patients with the disorder typically receive. The purpose of the current study was to explore characteristics of treatment received by those with panic disorder with and without agoraphobia, examine demographic and clinical predictors of receiving treatment, and explore treatment barriers. Methods This study uses data from the Primary Care Anxiety Project (PCAP), which is a naturalistic, longitudinal study of anxiety disorders in primary care patients. This study presents data on 235 PCAP participants diagnosed with panic disorder with (N=150) or without agoraphobia (N=85) at the study intake assessment. Results Many patients with panic disorder were not receiving psychiatric treatment at study intake, with those without agoraphobia being less likely to receive treatment. Psychotropic medications were the treatment of choice, with SSRIs/SNRIs being the most commonly received class of medications. Only 39% of those with panic disorder with agoraphobia and 24% of those without agoraphobia were receiving psychotherapy, and use of empirically supported interventions was rare. The most common treatment barriers were: not believing in utilizing medication/therapy for emotional problems and not receiving a treatment recommendation from one’s provider. Conclusions The findings suggest a need for better treatment dissemination, in addition to making interventions more accessible and/or adapting them to the particular needs of primary care patients.

Pathophysiology and management of multivalvular disease
Unger, Philippe; Clavel, Marie-Annick; Lindman, Brian R.; Mathieu, Patrick; Pibarot, Philippe
2016-01-01
Multivalvular disease (MVD) is a common condition with a complex pathophysiology, dependent on the specific combination of valve lesions. Diagnosis is challenging as several echocardiographic methods commonly used for the assessment of stenosis or regurgitation have been validated only in patients with single valve disease. Decisions about the timing and type of treatment should be made by a multidisciplinary heart valve team, on a case-by-case basis. Several factors should be considered, including the severity and consequences of the MVD, the patient’s life expectancy and comorbidities, the surgical risk associated with combined valve procedures, the long-term risk of morbidity and mortality associated with multiple valve prostheses, and the likelihood and risk of reoperation. The introduction of transcatheter valve therapies into clinical practice has provided new treatment options for patients with MVD, and decision-making algorithms on how to combine surgical and percutaneous treatment options are evolving rapidly. In this Review, we discuss the pathophysiology, diagnosis, and treatment of MVD, focussing on the combination of valve pathologies that are most often encountered in clinical practice. PMID:27121305

Little is known about the treatment of oedema in palliative care patients. To outline the assessment, goals, and interventions for patients with oedema. A 6-month chart review of a specialist physiotherapy-led oedema service was carried out. Of the sample group (n=63), 28.6% of patients had lymphoedema, 15.9% had non-lymphatic oedema, 46% had mixed oedema and 9.8% had lymphorrhoea; 58 patients (92%) had cancer. The most common interventions were providing education (100%, n=63), using compression garments (58%, n=37), bandaging (51%, n=32), exercise (38%, n=24), lymphatic massage and kinesio-taping (35%, n=22 each). Treatment regime differed depending on the type of oedema present. Treatment goals were pragmatic: the most common were to maintain skin quality (54%, n=34), reduce limb volume (52%, n=32), and improve quality of life (48%, n=30). Palliative care oedema can be treated using manual methods, including compression and massage. Goals differ from other oedema populations. Research is hampered by lack of suitable measures to record skin changes and quality of life.
Antibiotic use among older adults on an acute care general surgery service
Pollmann, André S.; Bailey, Jon G.; Davis, Philip J.B.; Johnson, Paul M.
2017-01-01
Background Antibiotics play an important role in the treatment of many surgical diseases that affect older adults, and the potential for inappropriate use of these drugs is high. Our objective was to describe antibiotic use among older adults admitted to an acute care surgery service at a tertiary care teaching hospital. Methods Detailed data regarding diagnosis, comorbidities, surgery and antibiotic use were retrospectively collected for patients 70 years and older admitted to an acute care surgery service. We evaluated antibiotic use (perioperative prophylaxis and treatment) for appropriateness based on published guidelines. Results During the study period 453 patients were admitted to the acute care surgery service, and 229 underwent surgery. The most common diagnoses were small bowel obstruction (27.2%) and acute cholecystitis (11.0%). In total 251 nonelective abdominal operations were performed, and perioperative antibiotic prophylaxis was appropriate in 49.5% of cases. The most common prophylaxis errors were incorrect timing (15.5%) and incorrect dose (12.4%). Overall 206 patients received treatment with antibiotics for their underlying disease process, and 44.2% received appropriate first-line drug therapy. The most common therapeutic errors were administration of second- or third-line antibiotics without indication (37.9%) and use of antibiotics when not indicated (12.1%). There was considerable variation in the duration of treatment for patients with the same diagnoses. Conclusion Inappropriate antibiotic use was common among older patients admitted to an acute care surgery service. Quality improvement initiatives are needed to ensure patients receive optimal care in this complex hospital environment. PMID:28930045

Introduction Despite remarkable advances in tumor treatment, many patients still die from common tumors (breast, prostate, lung, CNS, colon, and pancreas), and thus, new approaches are needed. Many of these tumors synthesize bombesin (Bn)-related peptides and over-express their receptors (BnRs), hence functioning as autocrine-growth-factors. Recent studies support the conclusion that Bn-peptides/BnRs are well-positioned for numerous novel antitumor treatments, including interrupting autocrine-growth via the use of over-expressed receptors for imaging and targeting cytotoxic-compounds, either by direct-coupling or combined with nanoparticle-technology. Areas covered The unique ability of common neoplasms to synthesize, secrete, and show a growth/proliferative/differentiating response due to BnR over-expression, is reviewed, both in general and with regard to the most frequently investigated neoplasms (breast, prostate, lung, and CNS). Particular attention is paid to advances in the recent years. Also considered are the possible therapeutic approaches to the growth/differentiation effect of Bn-peptides, as well as the therapeutic implication of the frequent BnR over-expression for tumor-imaging and/or targeted-delivery. Expert opinion Given that Bn-related-peptides/BnRs are so frequently ectopically-expressed by common tumors, which are often malignant and become refractory to conventional treatments, therapeutic interventions using novel approaches to Bn-peptides and receptors are being explored. Of particular interest is the potential of reproducing BnRs in common tumors, such as the recent success of utilizing overexpression of somatostatin-receptors by neuroendocrine-tumors to provide the most sensitive imaging methods and targeted delivery of cytotoxic-compounds.

The acute management of haemorrhoids
Cohen, CRG
2014-01-01
Introduction Although the acute thrombosis and strangulation of haemorrhoids is a common condition, there is no consensus as to its most effective treatment. Methods A PubMed search was undertaken for papers describing the aetiology and treatment of the acute complications of haemorrhoids. Results The anatomy and treatments for strangulated internal haemorrhoids and thrombosed perianal varices are discussed. Studies of the effectiveness and complications of conservative and operative treatments are reviewed. Conclusions Ambiguities exist in the terminology used to describe the two separate pathologies that make up the acute complications of haemorrhoids. These complications have traditionally been treated conservatively. There is evidence that early operative intervention for strangulated internal haemorrhoids is safe and effective. A suggested algorithm for treatment is given, based on the published literature. PMID:25245728

Objective: Premenstrual syndrome (PMS) is one of the most common problems among women of reproductive age. The popularity of complementary/alternative therapies has grown in recent years, and these treatments have been more commonly used by women (48.9%) than men (37.8%). The aim of this systematic review was to assess effectiveness and safety of Iranian herbal medicines for treatment of premenstrual syndrome. Methods: PubMed, Scopus, Cochrane, and Google Scholar were searched along with SID, Magiran and Irandoc up to Dec 2017. Inclusion criteria consist of Iranian, published, randomized controlled trials (RCTs) using Iranian herbal medicine for treatment of reproductive age women with PMS. Eventually Eighteen RCTs met the inclusion criteria. Results: Overall, studies have shown that Vitex agnuscastus, Hypericum perforatum, Matricaria chamomilla, saffron, Curcumin, Melissa officinalis, Zataria multiflora, Wheat Germ Extract, Echinophora platyloba, Foeniculum vulgare, Valerian root extract, Citrus sinensis, Zingiber officinale and Flax seed might alleviate symptoms of PMS. Conclusion: This research demonstrated efficacy and safety of Iranian herbal medicines in alleviating PMS. Therefore, herbal medicine can be regarded as an alternative treatment for women suffering from PMS. PMID:29632841

The current rate of deforestation in Africa constitutes a serious danger to the future of medicinal plants on this continent. Conservation of these medicinal plants in the field and the scientific documentation of our knowledge about them are therefore crucial. An ethnobotanical survey of plants used for the treatment of tuberculosis (TB) was carried out in selected areas of the Eastern Cape, South Africa. These areas were Hala, Ncera, Sheshegu, and Gquamashe, all within the Nkonkobe Municipality. One hundred informants were interviewed. The survey included the identification of scientific and vernacular names of the plants used for treatment of TB as well as the methods of preparation and administration, the part used, dosage, and duration of treatment. The survey revealed 30 plants belonging to 21 families which are commonly used by traditional healers for the treatment of TB and associated diseases. Of these plants Clausena anisata, Haemanthus albiflos, and Artemisia afra were the most cited. The leaves were the most common part used in the medicinal preparations. Our findings are discussed in relation to the importance of the documentation of medicinal plants. PMID:24864158
New Trends for the Evaluation of Heat Treatments of Milk
Di Costanzo, Maria Gabriella; Mattera, Maria
2017-01-01
Milk is generally very rich in nutrients and this may lead it to be an ideal growth environment for many microorganisms, including pathogens, so effective measurements aiming to ensure total microbiological safety of milk and minimize the risk to human health are needed. Milk heat treatments are the most common practices carried out to inhibit the microbial growth; therefore it is necessary to have analytical procedures that are more and more up-to-date and capable of detecting the effectiveness of the heat treatments. Most of the reference and official methods to assess heat treatment in milk are based on the evaluation of the modifications of some milk components following the thermal process, such as the determination of enzyme activities (alkaline phosphatase and lactoperoxidase), whey proteins, Maillard reaction compounds (generally furosine), and lactulose. Besides the most common techniques (liquid and gas chromatography, capillary electrophoresis, or spectroscopy) used for the detection of single thermal indicators, new approaches, such as chemometric studies or more recent techniques, including size-exclusion chromatography with online electrospray mass spectrometry or stable isotope ratio mass spectrometry, are discussed in this review in order to evaluate heat treatment in milk.

Objective To assess the prevalence, symptom severity, functional impairment, and treatment of major depressive episode (MDE) in the Iraqi general population. Methods The Iraq Mental Health Survey is a nationally representative face-to-face survey of 4,332 non-institutionalized adults aged 18+ interviewed in 2006–2007 as part of the WHO World Mental Health Surveys. Prevalence and correlates of DSM-IV MDE were determined with the WHO Composite International Diagnostic Interview (CIDI). Findings Lifetime and 12-month prevalence of MDE were 7.4% and 4.0%, respectively. Close to half (46%) of the 12-month MDE cases were severe/very severe. MDE was more common among women and those previously married. Median age of onset was 25.2. Only one-seventh of 12-month MDE cases received treatment despite being associated with very substantial role impairment (on average 70 days out of role in the past year). Conclusions MDE is a commonly occurring disorder in the Iraqi general population and is associated with considerable disability and low treatment. Efforts are needed to decrease the barriers to treatment and to educate general medical providers in Iraq about the recognition and treatment of depression. PMID:26230265

Background Acne is a chronic disease of the pilosebaceous unit that mainly affects adolescents. It is the most common dermatological problem, affecting approximately 80% of teenagers between 12 and 18 years of age. Diagnosis is clinical and is based on the patient’s age at the time the lesions first appear, and on its polymorphism, type of lesions, and their anatomical location. The right treatment for the right patient is key to treating acne safely. The aim of this investigational survey was to evaluate how Brazilian dermatologists in private practice currently manage acne. Materials and methods Dermatologists practicing in 12 states of Brazil were asked how they manage patients with grades I, II, III, and IV acne. Each dermatologist completed a written questionnaire about patient characteristics, acne severity, and the therapy they usually prescribe for each situation. Results In total, 596 dermatologists were interviewed. Adolescents presented as the most common acneic population received by dermatologists, and the most common acne grade was grade II. The doctors could choose more than one type of treatment for each patient, and treatment choices varied according to acne severity. A great majority of dermatologists considered treatment with drugs as the first alternative for all acne grades, choosing either topical or oral presentation depending on the pathology severity. Dermocosmetics were chosen mostly as adjunctive therapy, and their inclusion in the treatment regimen decreased as acne grades increased. Conclusion This survey illustrates that Brazilian dermatologists employ complex treatment regimens to manage acne, choosing systemic drugs, particularly isotretinoin, even in some cases of grade I acne, and heavily prescribe antibiotics. Because complex regimens are harder for patients to comply with, this result notably raises the question of adherence, which is a key factor in successful treatment. PMID:26609243

Background & aims Musculoskeletal pain, the most common cause of disability globally, is most frequently managed in primary care. People with musculoskeletal pain in different body regions share similar characteristics, prognosis, and may respond to similar treatments. This overview aims to summarise current best evidence on currently available treatment options for the five most common musculoskeletal pain presentations (back, neck, shoulder, knee and multi-site pain) in primary care. Methods A systematic search was conducted. Initial searches identified clinical guidelines, clinical pathways and systematic reviews. Additional searches found recently published trials and those addressing gaps in the evidence base. Data on study populations, interventions, and outcomes of intervention on pain and function were extracted. Quality of systematic reviews was assessed using AMSTAR, and strength of evidence rated using a modified GRADE approach. Results Moderate to strong evidence suggests that exercise therapy and psychosocial interventions are effective for relieving pain and improving function for musculoskeletal pain. NSAIDs and opioids reduce pain in the short-term, but the effect size is modest and the potential for adverse effects need careful consideration. Corticosteroid injections were found to be beneficial for short-term pain relief among patients with knee and shoulder pain. However, current evidence remains equivocal on optimal dose, intensity and frequency, or mode of application for most treatment options. Conclusion This review presents a comprehensive summary and critical assessment of current evidence for the treatment of pain presentations in primary care. The evidence synthesis of interventions for common musculoskeletal pain presentations shows moderate-strong evidence for exercise therapy and psychosocial interventions, with short-term benefits only from pharmacological treatments. Future research into optimal dose and application of the most promising treatments is needed. PMID:28640822
Basic principles of fracture treatment in children.
Ömeroğlu, Hakan
2018-04-01
This review aims to summarize the basic treatment principles of fractures according to their types and general management principles of special conditions including physeal fractures, multiple fractures, open fractures, and pathologic fractures in children. Definition of the fracture is needed for better understanding the injury mechanism, planning a proper treatment strategy, and estimating the prognosis. As the healing process is less complicated, remodeling capacity is higher and non-union is rare, the fractures in children are commonly treated by non-surgical methods. Surgical treatment is preferred in children with multiple injuries, in open fractures, in some pathologic fractures, in fractures with coexisting vascular injuries, in fractures which have a history of failed initial conservative treatment and in fractures in which the conservative treatment has no/little value such as femur neck fractures, some physeal fractures, displaced extension and flexion type humerus supracondylar fractures, displaced humerus lateral condyle fractures, femur, tibia and forearm shaft fractures in older children and adolescents and unstable pelvis and acetabulum fractures. Most of the fractures in children can successfully be treated by non-surgical methods.

The bunionette, or tailor's bunion, is a lateral prominence of the fifth metatarsal head. Most commonly, bunionettes are the result of a widened 4-5 intermetatarsal angle with associated varus of the metatarsophalangeal joint. When symptomatic, these deformities often respond to nonsurgical treatment methods, such as wider shoes and padding techniques. When these methods are unsuccessful, surgical treatment is based on preoperative radiographs and associated lesions, such as hyperkeratoses. In rare situations, a simple lateral eminence resection is appropriate; however, the risk of recurrence or overresection is high with this technique. Patients with a lateral bow to the fifth metatarsal are treated with a distal chevron-type osteotomy. A widened 4-5 intermetatarsal angle often requires a diaphyseal osteotomy for correction.
Photodynamic therapy--aspects of pain management.
Fink, Christine; Enk, Alexander; Gholam, Patrick
2015-01-01
Topical photodynamic therapy (PDT) is a highly effective and safe treatment method for actinic keratoses with an excellent cosmetic outcome and is commonly used for the therapy of large areas of photodamaged skin with multiple clinically manifest and subclinical lesions. However, the major drawback of photodynamic therapy is the pain experienced during the treatment that can be intense and sometimes even intolerable for patients, requiring interruption or termination of the process. Several strategies for controlling pain during photodynamic therapy have been studied but few effective methods are currently available. Therefore, this review puts the spotlight on predictors on pain intensity and aspects of pain management during photodynamic therapy. © 2014 Deutsche Dermatologische Gesellschaft (DDG).

2017-09-01
Partial thickness rotator cuff tears (PTRCTs) are a common pathology among shoulder disorders in people over 50 years. Treatment of PTRCTs remains controversial. Most studies on the treatment of PTRCTs have explained surgical techniques or outcomes; few studies have centralized on the conservative and new management of PTRCTs, like treatment with Platelet-rich plasma (PRP). These case series study have been conducted on Platelet-rich plasma (PRP) injection, as a concentrated source of cytokines that can stimulate healing of soft tissue. PRP injection showed positive effect on improving PTRCTs complains. This method improved pain, function, DASH score and shoulder joint range motion in. Because of PRP products are safe and easy to prepare and apply, and also according to improving patient's condition, this method can be used to treat PTRCTs.

Surgical treatment of patients under local anaesthesia is quite commonly restricted by limited compliance from the patient. An alternative to treatment under pharmacological sedation or general anaesthesia could be the application of medical hypnosis. With this method, both suggestive and autosuggestive procedures are used for anxiolysis, relaxation, sedation and analgesia of the patient. During a 1-year period of first clinical application, a total of 207 surgical procedures on a non-selected collective of 174 patients were carried out under combined local anaesthesia and medical hypnosis. Medical hypnosis proved to be a standardisable and reliable method by which remarkable improvements in treatment conditions for both patient and surgeons were achievable. Medical hypnosis is not considered to be a substitute for conscious sedation or general anaesthesia but a therapeutic option equally interesting for anaesthesists and surgeons.

Primary liver cancer (PLC) is one of the most common malignant tumors because of its high incidence and high mortality. Traditional Chinese medicine (TCM) plays an active role in the treatment of PLC. As the most important part in the TCM system, syndrome differentiation based on the clinical manifestations from traditional four diagnostic methods has met great challenges and questions with the lack of statistical validation support. In this study, we provided evidences for TCM syndrome differentiation of PLC using the method of analysis of latent structural model from clinic data, thus providing basis for establishing TCM syndrome criteria. And also we obtain the common syndromes of PLC as well as their typical clinical manifestations, respectively.
Molecular Markers Useful for Intraspecies Subtyping and Strain Differentiation of Dermatophytes.

Dermatophytosis is a very common skin disorder and the most frequent infection encountered by practicing dermatologists. The identification, pathogenicity, biology, and epidemiology of dermatophytes, the causative agents of dermatophytosis, are of interest for both dermatologists and medical mycologists. Recent advances in molecular methods have provided new techniques for identifying dermatophytes, including intraspecies variations. Intraspecies subtyping and strain differentiation have made possible the tracking of infections, the identification of common sources of infections, recurrence or reinfection after treatment, and analysis of strain virulence and drug resistance. This review describes molecular methods of intraspecies subtyping and strain differentiation, including analyses of mitochondrial DNA and non-transcribed spacer regions of ribosomal RNA genes, random amplification of polymorphic DNA, and microsatellite markers, along with their advantages and limitations.

Late complications of thrombosis of the deep veins in the region between the popliteal vein termination and the confluence of the common iliac veins and inferior vena cava (suprapopliteal deep-vein thrombosis) are common and often unrecognized by those responsible for the initial management. Pharmacomechanical-assisted clearance of the thrombus at the time of first presentation provides the best opportunity for complete recovery with preservation of normal venous valve function and avoidance of recurrent deep-vein thrombosis and postthrombotic syndrome. Recent interventional radiology methods provide for rapid and complete thrombolysis even in some patients in whom thrombolysis was previously considered contraindicated. This reviewmore » describes the methods, safety, and efficacy of acute interventional treatment of suprapopliteal deep-vein thrombosis.« less

Background Abdominal abscesses are a common complication in Crohn’s disease (CD). Percutaneous drainage of such abscesses has become increasingly popular and may deliver outcomes comparable to surgical treatment; however, such comparative data are limited from single center studies. There have been no nationally representative studies comparing different treatment modalities for abdominal abscesses. Methods We identified all adult CD-related non-elective hospitalizations from the Nationwide Inpatient Sample 2007 that were complicated by an intra-abdominal abscess. Treatment modality was categorized into 3 strata – medical treatment alone, percutaneous drainage, and surgery. We analyzed the nationwide patterns in the treatment and outcomes of each treatment modality and examined for patient demographic, disease, or hospital-related disparities in treatment and outcome. Results There were an estimated 3,296 hospitalizations for abdominal abscesses in patients with CD. Approximately 39% were treated by medical treatment alone, 29% with percutaneous drainage, and 32% with surgery with a significant increase in the use of percutaneous drainage since 1998 (7%). Co-morbidity burden, admission to a teaching hospital, and complicated Crohn’s disease (fistulae, stricture) were associated with non-medical treatment. Use of percutaneous drainage was more common in teaching hospitals. Mean time to percutaneous drainage and surgical treatment were 4.6 and 3.3 days respectively and early intervention was associated with significantly shorter hospitalization. Conclusions We describe the nationwide pattern in the treatment of abdominal abscesses and demonstrate an increase in the use of percutaneous drainage for the treatment of this subgroup. Early treatment intervention was predictive of shorter hospitalization. PMID:23392744

Gafchromic EBT3 film is widely used for patient specific quality assurance of complex treatment plans. Film dosimetry techniques commonly involve the use of transmission scanning to produce TIFF files, which are analysed using a non-linear calibration relationship between the dose and red channel net optical density (netOD). Numerous film calibration techniques featured in the literature have not been independently verified or evaluated. A range of previously published film dosimetry techniques were re-evaluated, to identify whether these methods produce better results than the commonly-used non-linear, netOD method. EBT3 film was irradiated at calibration doses between 0 and 4000 cGy and 25 pieces of film were irradiated at 200 cGy to evaluate uniformity. The film was scanned using two different scanners: The Epson Perfection V800 and the Epson Expression 10000XL. Calibration curves, uncertainty in the fit of the curve, overall uncertainty and uniformity were calculated following the methods described by the different calibration techniques. It was found that protocols based on a conventional film dosimetry technique produced results that were accurate and uniform to within 1%, while some of the unconventional techniques produced much higher uncertainties (> 25% for some techniques). Some of the uncommon methods produced reliable results when irradiated to the standard treatment doses (< 400 cGy), however none could be recommended as an efficient or accurate replacement for a common film analysis technique which uses transmission scanning, red colour channel analysis, netOD and a non-linear calibration curve for measuring doses up to 4000 cGy when using EBT3 film.

Acute and recurrent ankle sprains and other trauma to the ankle joint are common injuries in soccer and can be accompanied by or result in osteochondral lesions of the ankle joint, majorly of the talus. Conservative treatment frequently fails. Several operative treatment techniques exist; however, the choice of the right procedure is difficult due to lack of literature with a high level of evidence. We present our treatment method for acute and chronic ankle osteochondral lesions with cystic formation approached by a new surgical technique combining bone plasty and a collagen matrix (autologous matrix-induced chondrogenesis).

If we are to find treatments to postpone, reduce the risk of, or completely prevent the clinical onset of Alzheimer disease (AD), we need faster methods to evaluate promising preclinical AD treatments, new ways to work together in support of common goals, and a determination to expedite the initiation and performance of preclinical AD trials. In this article, we note some of the current challenges, opportunities and emerging strategies in preclinical AD treatment. We describe the Collaboration for Alzheimer's Prevention (CAP)-a convening, harmonizing and consensus-building initiative to help stakeholders advance AD prevention research with rigour, care and maximal impact-and we demonstrate the impact of CAP on the goals and design of new preclinical AD trials.

2017-03-01
Chronic fatigue is an important contributor to impaired health-related quality of life in Ehlers-Danlos syndrome. There is overlap in the symptoms and findings of EDS and chronic fatigue syndrome. A proportion of those with CFS likely have EDS that has not been identified. The evaluation of chronic fatigue in EDS needs to include a careful clinical examination and laboratory testing to exclude common causes of fatigue including anemia, hypothyroidisim, and chronic infection, as well as dysfunction of major physiological or organ systems. Other problems that commonly contribute to fatigue in EDS include sleep disorders, chronic pain, deconditioning, cardiovascular autonomic dysfunction, bowel and bladder dysfunction, psychological issues, and nutritional deficiencies. While there is no specific pharmacological treatment for fatigue, many medications are effective for specific symptoms (such as headache, menstrual dysfunction, or myalgia) and for co-morbid conditions that result in fatigue, including orthostatic intolerance and insomnia. Comprehensive treatment of fatigue needs to also evaluate for biomechanical problems that are common in EDS, and usually involves skilled physical therapy and attention to methods to prevent deconditioning. In addition to managing specific symptoms, treatment of fatigue in EDS also needs to focus on maintaining function and providing social, physical, and nutritional support, as well as providing on-going medical evaluation of new problems and review of new evidence about proposed treatments. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

This study assessed the use of intermediate endpoints in the economic evaluation of new treatments for advanced cancer and the methodological approaches adopted when overall survival (OS) data are unavailable or of limited use. A systematic literature review was conducted to identify economic evaluations of treatments for advanced cancer published between 2003 and 2013. Cost-effectiveness and cost-utility analyses expressed in cost per life-year gained and cost per quality-adjusted life-year using an intermediate endpoint as an outcome measure were eligible. Characteristics of selected studies were extracted and comprised population, treatment of interest, comparator, line of treatment, study perspective, and time horizon. Use of intermediate endpoints and methods adopted when OS data were lacking were analyzed. In total, 7219 studies were identified and 100 fulfilled the eligibility criteria. Intermediate endpoints mostly used were progression-free survival and time to progression, accounting for 92 % of included studies. OS data were unavailable for analysis in nearly 25 % of economic evaluations. In the absence of OS data, studies most commonly assumed an equal risk of death for all treatment groups. Other methods included use of indirect comparison based on numerous assumptions, use of a proxy for OS, consultation with clinical experts, and use of published external information from different treatment settings. Intermediate endpoints are widely used in the economic evaluation of new treatments for advanced cancer in order to estimate OS. Currently, different methods are used in the absence of suitable OS data and the choice of an appropriate method depends on many factors including the data availability.

Background and aims Female genital pain is a debilitating problem that negatively affects several aspects of the life of women. Several studies present figures of prevalence indicating that the problem affects nearly 20% of young women. However, many women fail to consult health care and the estimated prevalence therefore remains insecure. Historically, genital pain was commonly viewed as either physiological or psychosexual. Although the current field of research and clinical expertise in general agree upon a biopsychosocial conceptualization, less is known about the manifestation of the problem in everyday life and the experience of seeking health care among afflicted women. The objectives of the present study was to examine genital pain in a general female population living in Sweden cross-sectionally in terms of prevalence, sexual function, sexual satisfaction and help seeking, and to identify possible predictors of genital pain among women. Methods The study was a population-based study using a postal questionnaire administered to 4052 women (age 18--35). Of these 944 (response rate: 23%) took part in the study. Results Genital pain of six months duration was reported by 16.1% of the women. Women with pain more commonly reported fungal infections, other pain problems, sexual dysfunctions and symptoms of anxiety than pain-free women and in addition lower sexual satisfaction. There were no differences in sexual frequency. Pain was most commonly reported during sexual intercourse, but many women also experienced pain during non-sexual activities, with pain durations of several hours after the pain eliciting activity was interrupted. Of those reporting pain, 50% had sought care for their pain. The most common was to counsel a doctor and to receive topical treatment. However, the experienced effects of the treatments were on average low. In the explanatory model, fungal infections, and sexual dysfunctions were associated with genital pain. Conclusions The study had a low response rate, but still indicates that genital pain is common and negatively affects several aspects of women' life, not just sexual activities. Although many women report pro-longed pain experiences, many fail to consult health care and among those who seek care the effects of treatment are on average poor. There are strong associations between sexual dysfunctions (lack of sexual arousal, vaginal muscle tension hindering intercourse) and genital pain that, based on previous findings in this field of research, might be viewed in terms of circular maintaining processes. Implications Female genital pain is not just limited to the sexual context, but often negatively affects several situations in women' life. The size of the problem calls for immediate development of preventive interventions and treatment programs that focus on sexual education and to encourage a healthy sexuality among women and their partners. There is a need to identify methods in order to assemble evidence based interventions of female genital pain. Such methods are currently lacking, resulting in poor treatment options for women with pain.
Haemophilus influenzae: an underrated cause of vulvovaginitis in young girls.
Cox, R A
1997-01-01
AIMS: To establish the common pathogens associated with infective vulvovaginitis in young girls in the local population and to determine current management of this condition. METHODS: A prospective laboratory based survey was carried out over 19 months. A questionnaire was then sent to local general practitioners and hospital doctors. RESULTS: One hundred and six swabs were received during the study period of which 43 (40.5%) yielded organisms recognised as causes of vulvovaginitis. The most common pathogen was group A beta haemolytic streptococcus (19), with Haemophilus influenzae the second most common (11). Candida was isolated on nine occasions. The users' questionnaire had an overall response rate of 52%. Forty one per cent of respondents nominated candida as the most common cause of this condition. Forty six per cent were aware that beta haemolytic streptococci caused juvenile vulvovaginitis, but only four (3.6%) knew that H influenzae was a possible pathogen. The most popular agent for empirical treatment of vulvovaginitis was topical clotrimazole cream, although 24 respondents (22%) prescribed antibiotics that are active against both group A beta haemolytic streptococci and H influenzae. CONCLUSIONS: Although H influenzae is the second most common infective cause of juvenile vulvovaginitis in the local population, most doctors managing these patients were unaware of its importance and may not be prescribing appropriate empirical treatment.

Introduction Current treatments for Alzheimer's and other neurodegenerative diseases have only limited effectiveness meaning that there is an urgent need for new medications that could influence disease incidence and progression. We will investigate the potential of a selection of commonly prescribed drugs, as a more efficient and cost-effective method of identifying new drugs for the prevention or treatment of Alzheimer's disease, non-Alzheimer's disease dementias, Parkinson's disease and amyotrophic lateral sclerosis. Our research will focus on drugs used for the treatment of hypertension, hypercholesterolaemia and type 2 diabetes, all of which have previously been identified as potentially cerebroprotective and have variable levels of preclinical evidence that suggest they may have beneficial effects for various aspects of dementia pathology. Methods and analysis We will conduct a hypothesis testing observational cohort study using data from the Clinical Practice Research Datalink (CPRD). Our analysis will consider four statistical methods, which have different approaches for modelling confounding. These are multivariable adjusted Cox regression; propensity matched regression; instrumental variable analysis and marginal structural models. We will also use an intention-to-treat analysis, whereby we will define all exposures based on the first prescription observed in the database so that the target parameter is comparable to that estimated by a randomised controlled trial. Ethics and dissemination This protocol has been approved by the CPRD's Independent Scientific Advisory Committee (ISAC). We will publish the results of the study as open-access peer-reviewed publications and disseminate findings through national and international conferences as are appropriate. PMID:27965247

Background Exercise is associated with decreased recurrence risk, improved survival and quality of life for breast cancer survivors. However only an estimated 17% - 37% of survivors adhere to the American Cancer Society exercise guidelines. A critical first step to increase exercise among survivors is to understand how they believe exercise will effect them. Objective To explore common exercise outcome expectations among 20 female survivors of stage IA – IIB breast cancer who completed adjuvant treatment and an exercise intervention. Interventions/Methods A mixed-method descriptive study consisting of semi-structured telephone interviews assessed exercise outcome expectations and how the experience of cancer and its treatment influenced expected outcomes of exercise. The qualitative data were analyzed using a summative content analysis procedure; means were calculated for each item of the exercise outcome questionnaire. The qualitative and quantitative data were compared and contrasted. Results The sample was 70% Caucasian and 30% African American with a mean age was 62 years (± 8.5) and average time since treatment completion of 4.2 years (± 1.3). Three themes emerged from the interviews: 1) prevalence of common expectations, 2) pervasive impact of fatigue, and 3) a brighter future. Overall, findings revealed that breast cancer survivors have low levels of agreement that exercise may mitigate late and long-term cancer and treatment effects. Conclusions In general, breast cancer survivors (even those who are motivated to exercise) do not hold strong beliefs that exercise will decrease late and long-term treatment effects. Implications for Practice Clinicians can educate survivors about exercise benefits. PMID:26925999

Malaria in Honduras is endemic and accounts for 40% of the total cases in Central America. Our goal was to assess knowledge of preventive methods and current treatment of malaria among the affected community of Trujillo, Honduras. A cross-sectional survey was administered to 71 individuals. Most respondents had a good understanding about common malaria symptoms but not about the complications associated with severe cases. More important, we found that less than 20% of the respondents recognized indoor residual sprays and insecticide-treated nets as effective preventive measures, which are the most efficient preventive methods. Our study highlights the perceptions the people of Trujillo have about malaria. From our observations, we put forward recommendations to implement a comprehensive campaign to educate the Trujillo population about malaria preventive methods and to recruit local and international efforts to distribute insecticide-treated nets.
Thirty-eight cases of Bartholin's cyst treated with laser

Bartholin's cyst is a common disease of gynecology. It is cystic expansion of the gland tubes, which is caused by scar and infection. Forty years ago this disease was completely cut away by operation. In 1966, someone thought that cystostomy was a certain treatment method. Although there are many therapies used to treat this disease, e.g., incision drainage, excision, puncture, etc., they all have a better or worse side. In the past two years we used CO2 laser to treat patients in our hospital. Comparing outpatients with inpatients, the writer thinks that inpatients treated with laser (CO2) have less bleeding, less pain, faster recovery, and a higher success rate. This operation is done in the clinic and its both convenient and cheap. This method is one of the valuable methods which is worth spreading. From April 1989 to April 1991, 74 patients were treated with traditional operation and drug treatment. Another 38 patients were treated with the laser in the clinic. Clinical treatment results are contained here.

An ingrown toenail is a common, painful, and debilitating condition. This study aims to compare 2 surgical methods (partial matricectomy with curettage and electrocautery) in the treatment of ingrown toenails. A total of 92 ingrown nails of the big toe in 86 patients underwent partial matricectomy with curettage, whereas 57 ingrown nails of the big toe in 52 patients underwent partial matricectomy with electrocautery. Recurrence was observed in 2 toenails in the partial matricectomy with curettage group, whereas no recurrence was observed in the partial matricectomy with electrocautery group (p > .05). The mean period of postoperative pain was 2.3 and 3.1 days in the curettage group and the electrocautery group, respectively (p < .05). There was a significant difference in the duration of scar tissue inflammation (p < .05). Both surgical methods are safe treatment modalities with a high success rate. Partial matricectomy, which is achieved using curettage, seems to be superior to electrocautery in respect of reduced inflammation and duration of pain.

A modified cellulase enzyme assay was developed to monitor organic matter degradation in passive treatment systems for mine drainage. This fluorogenic substrate method facilitates assessment of exo-(1,4)-β-D-glucanase, endo-(1,4)-β-D-glucanase, and β-glucosidase, which compose an important cellulase enzyme system. The modified method was developed and refined using samples of organic carbon-amended mine tailings from field experiments where sulfate reduction was induced as a strategy for managing water quality. Sample masses (3 g) and the number of replicates ( ≥ 3) were optimized. Matrix interferences within these metal-rich samples were found to be insignificant. Application of this modified cellulase assay method provided insight into the availability and degradation of organic carbon within the amended tailings. Results of this study indicate that cellulase enzyme assays can be applied to passive treatment systems for mine drainage, which commonly contain elevated concentrations of metals.

Xenograft studies are commonly used to assess the efficacy of new compounds and characterise their dose-response relationship. Analysis often involves comparing the final tumour sizes across dose groups. This can cause bias, as often in xenograft studies a tumour burden limit (TBL) is imposed for ethical reasons, leading to the animals with the largest tumours being excluded from the final analysis. This means the average tumour size, particularly in the control group, is underestimated, leading to an underestimate of the treatment effect. Four methods to account for dropout due to the TBL are proposed, which use all the available data instead of only final observations: modelling, pattern mixture models, treating dropouts as censored using the M3 method and joint modelling of tumour growth and dropout. The methods were applied to both a simulated data set and a real example. All four proposed methods led to an improvement in the estimate of treatment effect in the simulated data. The joint modelling method performed most strongly, with the censoring method also providing a good estimate of the treatment effect, but with higher uncertainty. In the real data example, the dose-response estimated using the censoring and joint modelling methods was higher than the very flat curve estimated from average final measurements. Accounting for dropout using the proposed censoring or joint modelling methods allows the treatment effect to be recovered in studies where it may have been obscured due to dropout caused by the TBL.

Background We sought to assess injection practices, means of acquiring and disposing of syringes, and utilization and knowledge of harm reduction resources among injection drug users (IDUs) entering methadone maintenance treatment (MMT). Methods Interviews with 100 consecutive patients, including 35 IDUs, entering a MMT program in the Bronx, NY. Results Utilization of unsafe syringe sources was reported by 69% of IDUs in our sample. Most (80%) IDUs reused syringes, and syringe sharing was also common. Fewer than half knew that non-prescription pharmacy purchase of syringes was possible. The most common means of disposing of injecting equipment were the trash (63%) and syringe exchange programs (49%). Conclusions These findings indicate that drug users entering treatment under-utilize sanctioned venues to obtain sterile syringes or safely dispose of used injection equipment. Programs providing services to drug users should adopt a proactive stance to address the safety and health issues faced by injectors. PMID:16503997

Rosacea is a common, chronic, and poorly understood dermatological condition characterized by an inflammatory component composed of papules and pustules and a vascular component composed of flushing and erythema. Current treatment options include topical, systemic, and light-based methods, each of which focuses on either the inflammatory or the vascular component. Retinoids are not routinely indicated as treatment because of the common conception that they would be too inflammatory for the sensitive rosacea patient. However, photodamage may play a role in rosacea and tretinoin is well-known to repair photodamage. Thirty rosacea subjects were enrolled to assess their response to the use of clindamycin phosphate 1.2% and tretinoin 0.025% gel (ZIANA; Medicis Pharmaceutical Corporation, Scottsdale, AZ) for a period of 12 weeks. The results showed a dramatic decrease in pustules and papules without any significant inflammation or overall intolerance. No improvement in facial redness was achieved. Based on our results, more investigation of topical retinoids for rosacea treatment is prudent.

Research objectives This study sought to describe self-reported barriers to professional help seeking among college students who are at elevated suicide risk and determine if these barriers vary by demographic and clinical characteristics. Participants Participants were 165 non-treatment seekers recruited as part of a web-based treatment linkage intervention for college students at elevated suicide risk (from September 2010 through December 2011). Methods Data were collected using web-based questionnaires. Two coders coded students’ responses to an open-ended question about reasons for not seeking professional help. Results The most commonly reported barriers included: perception that treatment is not needed (66%); lack of time (26.8%); preference for self-management (18%). Stigma was mentioned by only 12% of students. There were notable differences based on gender, race, and severity of depression and alcohol abuse. Conclusions Efforts aimed at reaching students at elevated risk for suicidal behavior should be particularly sensitive to these commonly described barriers. PMID:24010494
Olecranon bursitis: a systematic overview
Hay, Bruce A; Bolt, Alexander M; Hay, Stuart M
2014-01-01
Background Olecranon bursitis is a common condition where the bursal cavity, superficial to the olecranon, becomes inflamed. This can occur either with or without infection and has been given pseudonyms relating to the repeated minor trauma from external pressure that often predisposes. As a result of the multiple aetiologies, olecranon bursitis can present to any medical specialty with reasonable frequency and, although many therapies are described, a single, evidence-based and standardized treatment pathway is not well described. Methods We summarize the key points within the literature and subsequently propose an evidence-based treatment pathway. Results Relevant evidence is presented from appropriate publications to add rational to existing decision-making processes, together with personal experience and suggested operative bursectomy techniques from an established upper limb surgeon. The common and significant aetiologies are summarized and, in particular, red flag symptoms are highlighted by way of warning to the unsuspecting investigator. Conclusions The conclusion is provided in diagrammatic form, providing a suggested treatment pathway from history and examination through to operative intervention. PMID:27582935

Juvenile dermatomyositis (JDM) is the most common form of idiopathic inflammatory myopathy in children. While outcomes are generally thought to be good, persistence of skin rash is a common problem. The goal of this study was to describe the development of clinical treatment plans (CTP) for children with JDM characterized by persistent skin rash despite complete resolution of muscle involvement. The Childhood Arthritis and Rheumatology Research Alliance, a North American consortium of pediatric rheumatologists and other healthcare providers, used a combination of Delphi surveys and nominal group consensus meetings to develop CTP that reflected consensus on typical treatments for patients with JDM with persistent skin rash. Consensus was reached on patient characteristics and outcome assessment. Patients should have previously received corticosteroids and methotrexate (MTX). Three consensus treatment plans were developed. Plan A added intravenous immunoglobulin (IVIG) if it was not already being used. Plan B added mycophenolate mofetil, while Plan C added cyclosporine. Continuation of previous treatments, including corticosteroids, MTX, and IVIG, was permitted in plans B and C. Three consensus CTP were developed for use in children with JDM and persistent skin rash despite complete resolution of muscle disease. These CTP reflect typical treatment approaches and are not to be considered treatment recommendations or standard of care. Using prospective data collection and statistical methods to account for nonrandom treatment assignment, it is expected that these CTP will be used to allow treatment comparisons, and ultimately determine the best treatment for these patients.
A pilot study of solar water disinfection in the wilderness setting.
Tedeschi, Christopher M; Barsi, Christopher; Peterson, Shane E; Carey, Kevin M
2014-09-01
Solar disinfection of water has been shown to be an effective treatment method in the developing world, but not specifically in a wilderness or survival setting. The current study sought to evaluate the technique using materials typically available in a wilderness or backcountry environment. Untreated surface water from a stream in rural Costa Rica was disinfected using the solar disinfection (SODIS) method, using both standard containers as well as containers and materials more readily available to a wilderness traveler. Posttreatment samples using polyethylene terephthalate (PET) bottles, as well as Nalgene and Platypus water containers, showed similarly decreased levels of Escherichia coli and total coliforms. The SODIS technique may be applicable in the wilderness setting using tools commonly available in the backcountry. In this limited trial, specific types of containers common in wilderness settings demonstrated similar performance to the standard containers. With further study, solar disinfection in appropriate conditions may be included as a viable treatment option for wilderness water disinfection. Copyright © 2014 Wilderness Medical Society.

Irreversible Electroporation of Human Primary Uveal Melanoma in Enucleated Eyes
Mandel, Yossi; Laufer, Shlomi; Belkin, Michael; Rubinsky, Boris; Pe'er, Jacob; Frenkel, Shahar
2013-01-01
Uveal melanoma (UM) is the most common primary intraocular tumor in adults and is characterized by high rates of metastatic disease. Although brachytherapy is the most common globe-sparing treatment option for small- and medium-sized tumors, the treatment is associated with severe adverse reactions and does not lead to increased survival rates as compared to enucleation. The use of irreversible electroporation (IRE) for tumor ablation has potential advantages in the treatment of tumors in complex organs such as the eye. Following previous theoretical work, herein we evaluate the use of IRE for uveal tumor ablation in human ex vivo eye model. Enucleated eyes of patients with uveal melanoma were treated with short electric pulses (50–100 µs, 1000–2000 V/cm) using a customized electrode design. Tumor bioimpedance was measured before and after treatment and was followed by histopathological evaluation. We found that IRE caused tumor ablation characterized by cell membrane disruption while sparing the non-cellular sclera. Membrane disruption and loss of cellular capacitance were also associated with significant reduction in total tumor impedance and loss of impedance frequency dependence. The effect was more pronounced near the pulsing electrodes and was dependent on time from treatment to fixation. Future studies should further evaluate the potential of IRE as an alternative method of uveal melanoma treatment. PMID:24039721

The data mining technique is adopted to analyze characteristics and rules of acupoint and meridian selection of acupuncture-moxibustion for treatment of vertigo at different time periods in the ancient. The data is collected from literature regarding acupuncture-moxibustion from the pre-Qin period to the end of Qing Dynasty, so as to establish a clinical literature database of ancient acupuncture-moxibustion for treatment of vertigo. Data mining method is applied to analyze the commonly used meridians, acupoints and special acupoints in different dynasties, also possible rules are explored. Totally 82 pieces of prescription of acupuncture-moxibustion for treatment of vertigo are included. In the history the leading selection of acupoitns are Fengchi (GB 20), Hegu (LI 4), Shangxing (GV 23) and Jiexi (ST 41) while that of meridians are mainly three yang meridians of foot and the Governor Vessel, especially the acupoints on the Bladder Meridian of foot yangming had the highest utilization rate, accounting for 23.04%. The acupoint selection is characterized by special acupoint, accounting for 80.6%, among which the crossing points are the most common choice. Distal-proximal acupoints combination is the most frequent method. The results indicate that the ancient acupuncture-moxibustion for treatment of vertigo focused on acupoints in the yang meridians, and the specific acupoints play an essential role in prescription; also the principle of syndrome differentiation and selecting acupoints along the meridians could be seen.

Failure of endodontic treatment is commonly due to Enterococcal infection. In this study influence of chemical treatments of type-I collagen membrane by chemical agents commonly used in endodontic treatment on Enterococcus faecalis cell adherence was evaluated. In order to determine the change in number of adhering bacteria after chemical treatment, confocal laser scanning microscopy was used. For this, overnight culture of E faecalis in All Culture broth was applied to chemically treated type-I collagen membrane. It was found that Ca(OH) II treated groups had statistically significant (p value=0.05) increase in population of bacteria adherence. The change in adhesion force between bacteria and collagen was determined by using optical tweezers (1064 nm). For this experiment, Type-I collagen membrane was soaked for 5 mins in a media that contained 50% all culture media and 50% saturated Ca(OH) II . The membrane was spread on the coverslip, on which diluted bacterial suspension was added. The force of laser tweezers on the bacteria was estimated at different trap power levels using viscous drag method and trapping stiffness was calculated using Equipartition theorem method. Presence of Ca(OH) II was found to increase the cell-substrate adherence force from 0.38pN to >2.1pN. Together, these experiments show that it was highly probable that the increase in adherence to collagen was due to a stronger adhesion in the presence of Ca (OH) II.

Antifungal susceptibility testing assists in finding the appropriate treatment for fungal infections, which are increasingly common. However, such testing is not very widespread. There are several existing methods, and the correlation between such methods was evaluated in this study. The susceptibility to fluconazole of 35 strains of Candida sp. isolated from blood cultures was evaluated by the following methods: microdilution, Etest, and disk diffusion. The correlation between the methods was around 90%. The disk diffusion test exhibited a good correlation and can be used in laboratory routines to detect strains of Candida sp. that are resistant to fluconazole.
Endoscopic treatment of intraventricular cystic tumors.
Margetis, Konstantinos; Souweidane, Mark M
2013-02-01
Intraventricular cystic tumors constitute a surgical challenge, because of their deep location and the histologically benign nature of most of them. We aim to present concisely, yet comprehensively, the role of neuroendoscopy in the treatment of intraventricular cystic tumors. A literature review searching for applications of endoscopy in the treatment of intraventricular cystic tumors is presented. Our experience is added to the presented data. In controversial issues, a comparison is made with traditional treatment methods. Intraventricular endoscopy has been successfully used in the treatment of the whole range of intraventricular cystic tumors. The most common indication is the treatment of colloid cysts. In the treatment of colloid cysts, a comparison with microsurgical techniques showed that endoscopy is advantageous in regard to operative morbidity and postoperative shunt dependency but is associated with a slightly higher recurrence rate. Intraventricular endoscopy has emerged as a viable option in the treatment of intraventricular cystic tumors. Copyright © 2013 Elsevier Inc. All rights reserved.

To compare the difference of the clinical efficacy on common peroneal palsy between the comprehensive therapy of electroacupuncture, moxibustion and moving cupping method and western medication. Ninety cases of common peroneal nerve palsy were randomized into a comprehensive therapy group and a western medication group, 45 cases in each one. In the comprehensive therapy group, electroacupuncture was applied to Yanglingquan (GB 34), Zusanli (ST 36), Xuanzhong (GB 39), Jiexi (ST 41), Taichong (LR 3), Zulinqi (GB 41) and the others, combined with warm moxibustion and moving cupping on the lateral side of the affected leg. The comprehensive therapy was used once a day. In the western medication group, vitamin B1 , 10 mg each time, 3 times a day; and mecobalamine, 0. 5 mg each time, three times a day were prescribed for oral administration. In the two groups, 15 days made one session, and the efficacy was observed after 2 sessions treatment. The total effective rate of the improvement of sensory function and motor nerve function was 97. 8% (44/45) in the comprehensive therapy group and was 82. 2% (37/ 45) in the western medication. The efficacy in the comprehensive therapy group was better than that of the western medication (P<0. 01). The electrophysiological examination showed that the amplitude of motor conduction of deep peroneal nerve and that of sensory conduction of surficial peroneal nerve after treatment were improved remarkably as compared with those before treatment in the comprehensive therapy group (both P<0. 05). The amplitude of motor conduction of deep peroneal nerve was improved significantly in the comprehensive therapy group as compared with that in the western medication group (P<0. 05). The comprehensive therapy of electroacupuncture, moxibustion and moving cupping method achieves the significant efficacy on common peroneal nerve palsy as compared with western medication.

Safe disposal of solid wastes containing heavy metals is a significant task for environment protection. Immobilization treatment is an effective technology to achieve this task. Cementitious material treatments and thermal treatments are two types of attractive immobilization treatments due to that the heavy metals could be encapsulated in their dense and durable wasteforms. This paper discusses the heavy metal immobilization mechanisms of these methods in detail. Physical encapsulation and chemical stabilization are two fundamental mechanisms that occur simultaneously during the immobilization processes. After immobilization treatments, the wasteforms build up a low permeable barrier for the contaminations. This reduces the exposed surface of wastes. Chemical stabilization occurs when the heavy metals transform into more stable and less soluble metal bearing phases. The heavy metal bearing phases in the wasteforms are also reviewed in this paper. If the heavy metals are incorporated into more stable and less soluble metal bearing phases, the potential hazards of heavy metals will be lower. Thus, converting heavy metals into more stable phases during immobilization processes should be a common way to enhance the immobilization effect of these immobilization methods.

[Osteosynthesis in the Surgical Treatment of Prognathism: State of The Art].
Durão, Nuno; Amarante, José
2017-03-31
Prognathism is a common skeletal facial abnormality, associated with class III malocclusion, often with repercussions in quality of life. In addition to orthodontic treatment, sagittal split ramus osteotomy is the most common technique for its correction, and segment osteosynthesis is an important element of the post-surgical outcome. A search for relevant literature was conducted in the PubMed/MEDLINE database and in other relevant sources. The stability of different fixation methods, their repercussions on inferior alveolar nerve lesions, and the type of material are among the most researched subjects. Recent research about the type of osteosynthesis applied in the sagittal split ramus osteotomy for mandibular setback is discussed. Miniplates appear to be the better option for fixation of sagittal split osteotomy for mandibular setback. Bioabsorbable osteosynthesis may be an acceptable alternative to titanium.
Supportive treatment for children with the common cold.
Ballengee, Cortney R; Turner, Ronald B
2014-02-01
This review summarizes recent developments in the supportive treatment of common cold symptoms in children. Conventional common cold therapies are no longer recommended for use in young children because of safety concerns. There are no studies that convincingly demonstrate the efficacy of any therapy for treatment of common cold symptoms in children less than 6 years of age and it is unlikely studies that establish efficacy can be done. Recent studies report a significant effect of probiotics on the occurrence of common cold illnesses in children, and studies in animals provide a plausible mechanism of action. These data suggest that the use of probiotics may have promise for the prevention of common cold illnesses in children. The effect of treatment on the severity of common cold symptoms cannot be accurately assessed with current study designs. In the absence of convincing evidence of efficacy, treatment of young children with symptomatic therapies cannot be recommended. Preliminary data suggest a small, beneficial effect of probiotics for the prevention of common cold illness.

Improvisational methods of music therapy have been increasingly applied in the treatment of individuals with autism spectrum disorder (ASD) over the past decades in many countries worldwide. This study aimed at developing treatment guidelines based on the most important common characteristics of improvisational music therapy (IMT) with children affected by ASD as applied across various countries and theoretical backgrounds. After initial development of treatment principle items, a survey among music therapy professionals in 10 countries and focus group workshops with experienced clinicians in three countries were conducted to evaluate the items and formulate revised treatment guidelines. To check usability, a treatment fidelity assessment tool was subsequently used to rate therapy excerpts. Survey findings and feedback from the focus groups corroborated most of the initial principles for IMT in the context of children with ASD. Unique and essential principles include facilitating musical and emotional attunement, musically scaffolding the flow of interaction, and tapping into the shared history of musical interaction between child and therapist. Raters successfully used the tool to evaluate treatment adherence and competence. Summarizing an international consensus about core principles of improvisational approaches in music therapy for children with ASD, these treatment guidelines may be applied in diverse theoretical models of music therapy. They can be used to assess treatment fidelity, and may be applied to facilitate future research, clinical practice, and training. © the American Music Therapy Association 2015. All rights reserved.

2014-01-01
Tears of the rotator cuff are common and becoming an increasingly frequent problem. There is a vast amount of literature on the merits and limitations of the various methods of clinical and radiological assessment of rotator cuff tears. This is also the case with regard to treatment strategies. Certain popular beliefs and principles practiced widely and the basis upon which they are derived may be prone to inaccuracy. We provide an overview of the historical management of rotator cuff tears, as well as an explanation for how and why rotator cuff tears should be managed, and propose a structured methodology for their assessment and treatment.

Background Recently Echinoderm microtubule-associated protein-like 4- anaplastic lymphoma kinase (EML4-ALK) fusion gene has become an important biomarker for ALK tyrosine kinase inhibitor (crizotinib) treatment in NSCLC. However, the best detection method and the significance of EML4-ALK variant types remain uncertain. Methods Reverse transcriptase-polymerase chain reaction (RT-PCR), fluorescence in Situ hybridization (FISH) and Immunohistochemical (IHC) stain were performed on tumor tissues of 312 NSCLC patients for detection of ALK rearrangements. Mutation analyses for EGFR and KRAS genes were also performed. Results Thirteen of the 312 patients (4.17%) had ALK rearrangements detected by RT-PCR. If RT-PCR data was used as the gold standard, FISH tests had a low sensitivity (58.33%), but very good specificity (99.32%). IHC stain had better sensitivity (91.67%) than FISH, but lower specificity (79.52%), when the cut off was IHC2+. All of the 8 patients with high abundance of EML4-ALK positive cells in tumor tissues (assessed by the signal intensities of the RT-PCR product), were also have high expression of ALK protein (IHC3+), and positive for FISH, except one failed in FISH. Variants 3a+3b (4/5, 80%) of EML4-ALK fusion gene were more common to have high abundance of EML4-ALK positive cells in tumor tissues than variant 1 (1/3, 33.3%). Meta-analysis of the published data of 2273 NSCLC patients revealed that variant 3 (23/44, 52.3%) was the most common type in Chinese population, while variant 1 (28/37, 75.7%) was most common in Caucasian. Conclusions Among the three detection methods, RT-PCR could detect not only the presence of EML4-ALK fusion gene and their variant types, but also the abundance of EML4-ALK positive cells in NSCLC tumor tissues. The latter two factors might affect the treatment response to anti-ALK inhibitor. Including RT-PCR as a diagnostic test for ALK inhibitor treatment in the prospective clinical trials is recommended.

Purpose: To develop a treatment planning method for passively-scattered involved-node proton therapy of mediastinal lymphoma robust to breathing and cardiac motions. Methods: Beam-specific planning treatment volumes (bsPTV) are calculated for each proton field to incorporate pertinent uncertainties. Geometric margins are added laterally to each beam while margins for range uncertainty due to setup errors, breathing, and calibration curve uncertainties are added along each beam. The calculation of breathing motion and deformation effects on proton range includes all 4DCT phases. The anisotropic water equivalent margins are translated to distances on average 4DCT. Treatment plans are designed so each beam adequately coversmore » the corresponding bsPTV. For targets close to the heart, cardiac motion effects on dosemaps are estimated by using a library of anonymous ECG-gated cardiac CTs (cCT). The cCT, originally contrast-enhanced, are partially overridden to allow meaningful proton dose calculations. Targets similar to the treatment targets are drawn on one or more cCT sets matching the anatomy of the patient. Plans based on the average cCT are calculated on individual phases, then deformed to the average and accumulated. When clinically significant dose discrepancies occur between planned and accumulated doses, the patient plan is modified to reduce the cardiac motion effects. Results: We found that bsPTVs as planning targets create dose distributions similar to the conventional proton planning distributions, while they are a valuable tool for visualization of the uncertainties. For large targets with variability in motion and depth, integral dose was reduced because of the anisotropic margins. In most cases, heart motion has a clinically insignificant effect on target coverage. Conclusion: A treatment planning method was developed and used for proton therapy of mediastinal lymphoma. The technique incorporates bsPTVs compensating for all common sources of uncertainties and estimation of the effects of cardiac motion not commonly performed.« less

Introduction: Hip spica casting is an important component of treatment for developmental dysplasia of the hip (DDH) and popular treatment method for femur fractures in children. Breakage at the hip region is a relatively common problem of this cast. We have developed a three-slab technique of hip spica application using fibreglass as the cast material. The purpose of this review was to evaluate the physical durability of the spica cast and skin complications with its use. Methodology: A retrospective review of children with various conditions requiring hip spica immobilisation which was applied using our method. Study duration was from 1st of January 2014 until 31st December 2015. Our main outcomes were cast breakage and skin complications. For children with hip instability, the first cast would be changed after one month, and the second cast about two months later. Results: Twenty-one children were included, with an average age of 2.2 years. The most common indication for spica immobilisation was developmental dysplasia of the hip. One child had skin irritation after spica application. No spica breakage was noted. Conclusion: This study showed that the three-slab method of hip spica cast application using fibreglass material was durable and safe with low risk of skin complications. PMID:28553442

Background. Despite recent advances in dental caries prevention, caries is common and remains a serious health problem. Laser irradiation is one of the most common methods in preventive measures in recent years. Raman spectroscopy technique is utilized to study the microcrystalline structure of dental enamel. In this study, FT-Raman spectroscopy was used to evaluate chemical changes in enamel structure irradiated with Nd:YAG and Er:YAG lasers. Methods. We used 15 freshly-extracted, non-carious, human molars that were treated as follows: No treatment was carried out in group A (control group); Group B was irradiated with Er:YAG laser for 10 seconds under air and water spray; and Group C was irradiated with Nd:YAG laser for 10 seconds under air and water spray. After treatment, the samples were analyzed by FT-Raman spectroscopy. Results. The carbonate content evaluation with regard to the integrated area under the curve (1065/960 cm–1) exhibited a significant reduction in its ratio in groups B and C. The organic content (2935/960 cm-1) area exhibited a significant decrease after laser irradiation in group B and C. Conclusion. The results showed that the mineral and organic matrices of enamel structure were affected by laser irradiation; therefore, it might be a suitable method for caries prevention. PMID:28096945
Pain management of musculoskeletal injuries in children: current state and future directions.

Pain is the most common reason for seeking health care in the Western world and is a contributing factor in up to 80% of all emergency department (ED) visits. In the pediatric emergency setting, musculoskeletal injuries are one of the most common painful presentations. Inadequate pain management during medical care, especially among very young children, can have numerous detrimental effects. No standard of care exists for the management of acute musculoskeletal injury-related pain in children. Within the ED setting, pain from such injuries has been repeatedly shown to be undertreated. Upon completion of this CME article, the reader should be better able to (1) distinguish multiple nonpharmacological techniques for minimizing and treating pain and anxiety in children with musculoskeletal injuries, (2) apply recent medical literature in deciding pharmacological strategies for the treatment of children with musculoskeletal injuries, and (3) interpret the basic principles of pharmacogenomics and how they relate to analgesic efficacy. Pediatric musculoskeletal injuries are both common and painful. There is growing evidence that, in addition to pharmacological therapy, nonpharmacological methods can be introduced to improve analgesia in the ED and after discharge. Traditionally, acetaminophen with codeine has been used to treat moderate orthopedic injury-related pain in children. Other oral opioids (hydrocodone, oxycodone) are gaining popularity, as well. Current data suggest that ibuprofen is at least as effective as acetaminophen-codeine and codeine alone. Medication compliance might be improved if adverse effects were minimized, and ibuprofen has been shown to have a similar or better adverse effect profile than the oral opioids to which it has been compared. Pharmacogenomic data show that nearly 50% of individuals have at least 1 reduced functioning allele resulting in suboptimal conversion of codeine to active analgesic, so it is not surprising that codeine analgesic efficacy is not optimal. At the same time, nonpharmacological therapies are emerging as commonly used treatment options by parents and adjuncts to analgesic medication. The efficacy and role of techniques (massage, music therapy, transcutaneous electrical nerve stimulation), although promising, require further clarification in the treatment of orthopedic injury pain. There is a need to optimize the measurement, documentation, and treatment of pain in children. There is growing evidence that nonpharmacological methods can be introduced to improve analgesia in the ED, and efforts to help parents implement these methods at home might be advantageous to optimize outpatient treatment plans. In pharmacotherapy, ibuprofen has emerged as an appropriate first-line choice for mild-moderate orthopedic pain. Other oral opioids (hydrocodone, oxycodone) are gaining popularity over codeine, because of the current understanding of the pharmacogenomics of such medications.

Acute leukaemia is the most common type of childhood cancer, the acute lymphoblastic type accounting for the majority of cases. Children affected by leukaemia receive various forms of treatments including chemotherapeutic agents and stem cell transplants. Leukaemia and its treatment can directly or indirectly affect oral health and further dental treatments. The oral complications include mucositis, opportunistic infections, gingival inflammation and bleeding, xerostomia and carious lesions. An additional consideration in children is the impact of the treatments on the developing dentition and on orofacial growth. The aim of this review is to describe the oral complications in children with acute lymphoblastic leukaemia and the methods of prevention and management before, during and after the cancer treatment. © 2014 John Wiley & Sons A/S.

Tourette syndrome (TS) among young people is associated with psychosocial difficulties and parents play an important role in the management of the condition. Clinical guidelines have been developed for the treatment of TS and tics, but little is known about how young people and their parents perceive their treatment options or their desired outcomes of treatment. The aim of this study is to explore perceptions of treatments for tics among young people with TS and their parents. In-depth interviews with 42 young people with TS and a mixed-methods, online survey of 295 parents of young people with TS. Participant recruitment was conducted through Tourettes Action (TA): a non-profit UK organisation for the support of people with TS. Interview transcripts were analysed using thematic analysis and responses to survey open-ended questions were analysed using content analysis. Triangulation of qualitative and quantitative data from the parents' survey and qualitative data from the interviews with young people was used to increase the validity and depth of the findings. A strong theme was the perception that health professionals have limited knowledge of TS and its treatment. Medication was a common treatment for tics and both young people and parents described benefits of medication. However, adverse effects were frequently described and these were a common reason for stopping medication among young people. Aripiprazole was viewed most positively. Access to behavioural interventions for tics was limited and 76% of parents wanted this treatment to be available for their child. Some young people had reservations about the effectiveness or practicality of behavioural interventions. Reduction and abolition of tics were desired outcomes of treatment, but both parents and young people also identified the importance of increasing control over tics and reducing anxiety-related symptoms. For young people, managing the urge to tic was an important outcome of treatment. The results suggest a need for more training in the identification and management of TS and wider availability of behavioural treatments. Clinical trials could explore the effectiveness of Aripiprazole used in combination with psycho-educational interventions to reduce anxiety and promote a sense of control.

Prader-Willi syndrome (PWS) is the most common form of obesity with a genetic basis. The short expected survival time due to numerous accompanying diseases and their complications is the reason for research on the maximally efficient method of treatment of obesity in this syndrome. Undertaken attempts of conservative treatment, for example with somatostatin, are ineffective. It seems that the only effective treatment of obesity in this syndrome may be surgical. In this article we present 2 cases of patients with PWS who underwent surgery consisting of biliopancreatic diversion (BPD)/Scopinaro procedure. The BPD/Scopinaro operation in selected cases of disciplined patients with a co-operative family, which we find of key importance, can be considered as one option of treatment of this syndrome in patients with prior neglect of conservative treatment.

Nano-liposomes are the newly developed delivery systems for cancer therapy that are finding a position particularly suitable as peptide and protein carriers. These are three-layered self-assembled structures with nanoparticulate carrier systems. The overall pharmacological properties of commonly used protein and peptide in cancer therapy can be improved by the incorporation of protein and peptide into the nano-liposome. The surface modifications can be made liposomes to make compatible with targeting ligands has made these nanocarriers for targeted delivery. This review discusses the method of preparation and characterization of liposome based protein peptide delivery for the treatment of cancer. This review also explores latest work intended for targeted treatment of cancer by nano-liposomal protein and peptide delivery system. This type of delivery is targeting protein and peptide to tumor site by avoiding the reticuloendothelial system. Methods of nano-liposome delivery containing protein and peptide are also highlighted.

Carpet is known to be a reservoir for biological contaminants, such as dust mites, dust mite allergen, and mold, if it is not kept clean. The accumulation of these contaminants in carpet might trigger allergies or asthma symptoms in both children and adults. The purpose of this study is to compare methods for removal of dust mites, dust mite allergens, and mold from carpet. Carpets were artificially worn to simulate 1 to 2 years of wear in a four-person household. The worn carpets were inoculated together with a common indoor mold (Cladosporium species) and house dust mites and incubated for 6 weeks to allow time for dust mite growth on the carpet. The carpets were randomly assigned to one of the four treatment groups. Available treatment regimens for controlling carpet contaminants were evaluated through a literature review and experimentation. Four moderately low-hazard, nondestructive methods were selected as treatments: vacuuming, steam-vapor, Neem oil (a natural tree extract), and benzalkonium chloride (a quaternary ammonium compound). Steam vapor treatment demonstrated the greatest dust mite population reduction (p < 0.05) when compared to other methods. The two physical methods, steam vapor and vacuuming, have no statistically significant efficacy in inactivating dust mite allergens (p = 0.084), but have higher efficacy when compared to the chemical method on dust mite allergens (p = 0.002). There is no statistically significant difference in the efficacy for reducing mold in carpet (p > 0.05) for both physical and chemical methods. The steam-vapor treatment effectively killed dust mites and denatured dust mite allergen in the laboratory environment.

Introduction In cases of haemorrhoidal disease resistant to conservative treatment, surgical treatment is necessary to relieve the symptoms. Aim To investigate the current methods used by Polish surgeons. Material and methods Surveys were distributed to members of the Association of Polish Surgeons (APS), in which participants were asked a number of closed-ended questions regarding haemorrhoidal disease and the way they treated suffering patients Results Out of the 1523 members of APS who received questionnaires, responses were received from 807 (52.9%) members. The Milligan-Morgan technique was indicated by 72.5% of surgeons as a leading surgical treatment, followed by Ligasure (15.5%), Ferguson (3.5%), DGHL (3.5%), other methods (3.5%), Parks (1.7%), and Longo (0%). The majority of participants (93%) indicated from 0 to 1 life threatening complications, 5% – from 2 to 3, and 2% > 4. A total of 83% of participants use a single dose of antibiotics prior to surgery. Conclusions The Milligan-Morgan technique is the preferred method. The majority of procedures are performed in regional hospitals and university departments, and less commonly in private practices. The vast majority of surgeons in Poland are not convinced about the stapler technique, justifying this fact with the possibility of developing serious complications PMID:27350838
Estimating scaled treatment effects with multiple outcomes.
Kennedy, Edward H; Kangovi, Shreya; Mitra, Nandita
2017-01-01
In classical study designs, the aim is often to learn about the effects of a treatment or intervention on a single outcome; in many modern studies, however, data on multiple outcomes are collected and it is of interest to explore effects on multiple outcomes simultaneously. Such designs can be particularly useful in patient-centered research, where different outcomes might be more or less important to different patients. In this paper, we propose scaled effect measures (via potential outcomes) that translate effects on multiple outcomes to a common scale, using mean-variance and median-interquartile range based standardizations. We present efficient, nonparametric, doubly robust methods for estimating these scaled effects (and weighted average summary measures), and for testing the null hypothesis that treatment affects all outcomes equally. We also discuss methods for exploring how treatment effects depend on covariates (i.e., effect modification). In addition to describing efficiency theory for our estimands and the asymptotic behavior of our estimators, we illustrate the methods in a simulation study and a data analysis. Importantly, and in contrast to much of the literature concerning effects on multiple outcomes, our methods are nonparametric and can be used not only in randomized trials to yield increased efficiency, but also in observational studies with high-dimensional covariates to reduce confounding bias.
Cost-Effectiveness Models in Age-Related Macular Degeneration: Issues and Challenges.
Schmier, Jordana K; Hulme-Lowe, Carolyn K
2016-03-01
Age-related macular degeneration (AMD) is a common ophthalmic condition that can have few symptoms in its early stage but can progress to major visual impairment. While there are no treatments for early-stage AMD, there are multiple modalities of treatment for advanced disease. Given the increasing prevalence of the disease, there are dozens of analyses of cost effectiveness of AMD treatments, but methods and approaches vary broadly. The goal of this review was to identify, characterize, and critique published models in AMD and provide guidance for their interpretation. After a literature review was performed to identify studies, and exclusion criteria applied to limit the review to studies comparing treatments for AMD, we compared methods across the 36 studies meeting the review criteria. To some extent, variation was related to targeting different audiences or acknowledging the most appropriate population for a given treatment. However, the review identified potential areas of uncertainty and difficulty in interpretation, particularly regarding duration of observation periods and the importance of visual acuity as an endpoint or a proxy for patient-reported utilities. We urge thoughtful consideration of these study characteristics when comparing results.

Benign prostatic hyperplasia (BPH) is a common disease in older men that can lead to lower urinary tract symptoms (LUTS). After failure of medical treatment, surgical managements has to be considered. Surgical management of lower urinary tract symptoms attributed to BPH has progressed over time as urologic surgeons search for more innovative and less invasive forms of treatment. Transurethral resection of the prostate (TURP) has long been the "gold standard" to which all other forms of treatment are compared. There are several different methods of surgical treatment of BPH, including whole gland enucleation, laser vaporization, and induction of necrosis with delayed reabsorption as well as hybrid techniques. As with any form of surgical intervention, long-term results define success. Long-term follow-up consists of examining overall efficacy with attention to associated adverse events. TURP has the luxury of the longest follow-up, while less invasive forms of treatment starting to acquire long-term data. There are several surgical options for BPH; newer methods do show promise, while the "gold standard" continues to demonstrate excellent surgical results.

This review deals with the role of microorganisms in spontaneous regression of a tumour. Spontaneous cancer regression is a phenomenon that has been described for many centuries. One of the most well known methods of inducing spontaneous regression of cancer is the application of Coley’s toxin (heat-killed Streptococcus pyogenes and Serratia marcescens), which has been used for the successful treatment of sarcomas, carcinomas, lymphomas, myelomas and melanomas. In clinical practice, the use of Bacillus Calmette-Guérin vaccine for the treatment of superficial urinary bladder cancer is the most common instance of the application of microorganisms for the treatment of cancer. This review provides further information on other tested bacteria – Clostridium spp., Bifidobacterium spp., Lactobacillus spp. and Salmonella spp. – in this field of study. Among new age methods, bactofection, alternative gene therapy, combination bacteriolytic therapy and bacteria-directed enzyme prodrug therapy are some of the potential cancer treatment modalities that use microorganisms. We have also provided information about the interconnection among microorganisms, immune system response, and the possible mechanisms involved in the spontaneous regression of tumours. PMID:26813865

Child/Adolescent Anxiety Multimodal Study (CAMS): rationale, design, and methods
2010-01-01
Objective To present the design, methods, and rationale of the Child/Adolescent Anxiety Multimodal Study (CAMS), a recently completed federally-funded, multi-site, randomized placebo-controlled trial that examined the relative efficacy of cognitive-behavior therapy (CBT), sertraline (SRT), and their combination (COMB) against pill placebo (PBO) for the treatment of separation anxiety disorder (SAD), generalized anxiety disorder (GAD) and social phobia (SoP) in children and adolescents. Methods Following a brief review of the acute outcomes of the CAMS trial, as well as the psychosocial and pharmacologic treatment literature for pediatric anxiety disorders, the design and methods of the CAMS trial are described. Results CAMS was a six-year, six-site, randomized controlled trial. Four hundred eighty-eight (N = 488) children and adolescents (ages 7-17 years) with DSM-IV-TR diagnoses of SAD, GAD, or SoP were randomly assigned to one of four treatment conditions: CBT, SRT, COMB, or PBO. Assessments of anxiety symptoms, safety, and functional outcomes, as well as putative mediators and moderators of treatment response were completed in a multi-measure, multi-informant fashion. Manual-based therapies, trained clinicians and independent evaluators were used to ensure treatment and assessment fidelity. A multi-layered administrative structure with representation from all sites facilitated cross-site coordination of the entire trial, study protocols and quality assurance. Conclusions CAMS offers a model for clinical trials methods applicable to psychosocial and psychopharmacological comparative treatment trials by using state-of-the-art methods and rigorous cross-site quality controls. CAMS also provided a large-scale examination of the relative and combined efficacy and safety of the best evidenced-based psychosocial (CBT) and pharmacologic (SSRI) treatments to date for the most commonly occurring pediatric anxiety disorders. Primary and secondary results of CAMS will hold important implications for informing practice-relevant decisions regarding the initial treatment of youth with anxiety disorders.

To compare the efficacy of zinc acetate lozenges with zinc gluconate lozenges in common cold treatment and to examine the dose-dependency of the effect. Meta-analysis. Placebo-controlled zinc lozenge trials, in which the zinc dose was > 75 mg/day. The pooled effect of zinc lozenges on common cold duration was calculated by using inverse-variance random-effects method. Seven randomised trials with 575 participants with naturally acquired common colds. Duration of the common cold. The mean common cold duration was 33% (95% CI 21% to 45%) shorter for the zinc groups of the seven included trials. Three trials that used lozenges composed of zinc acetate found that colds were shortened by 40% and four trials that used zinc gluconate by 28%. The difference between the two salts was not significant: 12 percentage points (95% CI: -12 to + 36). Five trials used zinc doses of 80-92 mg/day, common cold duration was reduced by 33%, and two trials used zinc doses of 192-207 mg/day and found an effect of 35%. The difference between the high-dose and low-dose zinc trials was not significant: 2 percentage points (95% CI: -29 to + 32). Properly composed zinc gluconate lozenges may be as effective as zinc acetate lozenges. There is no evidence that zinc doses over 100 mg/day might lead to greater efficacy in the treatment of the common cold. Common cold patients may be encouraged to try zinc lozenges for treating their colds. The optimal lozenge composition and dosage scheme need to be investigated further.

An increasing amount of attention has been paid to treatment resistant depression. Although it is quite common to observe nonremission to not just one but consecutive antidepressant treatments during a major depressive episode, a relationship between the likelihood of achieving remission and one's degree of resistance is not clearly known at this time. This study was undertaken to empirically test 2 recent models for staging treatment resistance. Psychiatrists from 2 academic sites reviewed charts of patients on their caseloads. Clinical Global Impressions-Severity (CGI-S) and Clinical Global Impressions-Improvement (CGI-I) scales were used to measure severity of depression and response to treatment, and 2 treatment-resistant staging scores were classified for each patient using the Massachusetts General Hospital staging method (MGH-S) and the Thase and Rush staging method (TR-S). Out of the 115 patient records reviewed, 58 (49.6%) patients remitted at some point during treatment. There was a significant positive correlation between the 2 staging scores, and logistic regression results indicated that greater MGH-S scores, but not TR-S scores, predicted nonremission. This study suggests that the hierarchical manner in which the field has typically gauged levels of treatment resistance may not be strongly supported by empirical evidence. This study suggests that the MGH staging model may offer some advantages over the staging method by Thase and Rush, as it generates a continuous score that considers both number of trials and intensity/optimization of each trial.

Patient preferences are an important topic of study with respect to attention-deficit hyperactivity disorder (ADHD) interventions, as there are multiple treatment choices available, multiple developmental levels to consider, and multiple potential individuals involved in treatment (children, parents, and adults with ADHD). Stated preference methods such as discrete choice experiment (DCE), best-worst scaling (BWS), and other utility value methods such as standard gamble interview (SGI) and time trade-off (TTO) are becoming more common in research addressing preferences for ADHD treatments. A synthesis of this research may facilitate improved patient-centered and family-centered treatment for ADHD. The purpose of this review was to synthesize reports across existing DCE, BWS, TTO, and SGI studies to assess which aspects of ADHD treatment are most studied as well as most preferred and influential in treatment decisions. MEDLINE, PsycINFO. A total of 41 studies referring to preferences for ADHD treatment were identified through the initial search and contact with researchers. Of these, 13 reported ADHD treatment preference data from a study using DCE, BWS, or SGI methods. No TTO studies were identified that met inclusion criteria. Methods and designs varied considerably across studies. Relatively few studies focused on preferences among children, adolescents, and adults compared with those that focused on the preferences of parents of children with ADHD. The majority of studies focused primarily on medication treatments, with many fewer focused on psychosocial treatments. Some studies indicated that parents of children with ADHD prefer to avoid stimulant medications in favor of behavioral or psychosocial interventions. Others report that parents see medication as a preferred treatment. Treatment outcome is a particularly salient attribute for treatment decisions for many informants. Potential outcomes of various treatments play a proximal role in patients' and families' decisions for ADHD treatment. Because the majority of studies focus on medication treatments for children with ADHD, more research is necessary to understand preferences related to behavioral and other psychosocial treatments both as stand-alone interventions and used in combination with medication. Additional research is also needed to assess the treatment preferences of adults with ADHD. In general, DCE, BWS, and SGI methods allow measurement of patient preferences in a manner that approximates the uncertainty and trade-offs inherent in real-world treatment decision making and provides valuable information to inform patient-centered and family-centered treatment.
Matching weights to simultaneously compare three treatment groups: Comparison to three-way matching

BACKGROUND Propensity score matching is a commonly used tool. However, its use in settings with more than two treatment groups has been less frequent. We examined the performance of a recently developed propensity score weighting method in the three treatment group setting. METHODS The matching weight method is an extension of inverse probability of treatment weighting (IPTW) that reweights both exposed and unexposed groups to emulate a propensity score matched population. Matching weights can generalize to multiple treatment groups. The performance of matching weights in the three-group setting was compared via simulation to three-way 1:1:1 propensity score matching and IPTW. We also applied these methods to an empirical example that compared the safety of three analgesics. RESULTS Matching weights had similar bias, but better mean squared error (MSE) compared to three-way matching in all scenarios. The benefits were more pronounced in scenarios with a rare outcome, unequally sized treatment groups, or poor covariate overlap. IPTW’s performance was highly dependent on covariate overlap. In the empirical example, matching weights achieved the best balance for 24 out of 35 covariates. Hazard ratios were numerically similar to matching. However, the confidence intervals were narrower for matching weights. CONCLUSIONS Matching weights demonstrated improved performance over three-way matching in terms of MSE, particularly in simulation scenarios where finding matched subjects was difficult. Given its natural extension to settings with even more than three groups, we recommend matching weights for comparing outcomes across multiple treatment groups, particularly in settings with rare outcomes or unequal exposure distributions.

Although weeding young northern hardwoods is not a common practice, most foresters will agree that weeding such stands is silviculturally sound in terms of improved growth and quality. Major obstacle to the widespread weeding of young stands as a routine cultural treatment is lack of information about the techniques and costs involved.

Common decision limits --The need for harmonised immunoassays.
Sturgeon, Catharine M
2014-05-15
The main aim of clinical guidelines is to encourage the best clinical outcome for patients and the best use of resources, no matter where patients are investigated or managed. Where guidelines incorporate decision limits based on levels of analytes in serum, plasma or urine these may determine whether or not to treat or may be used to tailor further treatment. Consideration should be given to the effect of method-related differences in results when implementing common decision limits. Available evidence suggests that for some analytes the implications for the patient may be serious, e.g. in terms of missed biopsies or unnecessary prostatic biopsies when prostate specific antigen is measured. Major causes of between-method differences are reviewed and means of addressing them considered. Copyright © 2013 Elsevier B.V. All rights reserved.

Clubfoot is the most common musculoskeletal birth defect, characterized by abnormal tendon and muscle development, leading to abnormal bone alignment of the feet. The Ponseti method is considered the gold standard in clubfoot treatment, and consists of a series of plaster castings, followed by 4 years of brace use. The most common cause of clubfoot relapse is nonadherence with the bracing protocol by the child's caretakers. The purpose of this study was to design, implement, and evaluate an educational bracing program for parents of children with clubfoot in an effort to improve bracing adherence. The educational bracing program for parents of children with clubfoot was designed with incorporation of findings from previous research, adult teaching methodology, and parental feedback. An educational brochure and a practice doll were created for use in educational sessions with parents during routine treatment visits. Two educational sessions were conducted with a health educator, employing identical questionnaires to assess changes in parental knowledge and skills upon completion of the program. Thirty parents completed the educational bracing program, and the majority reported increased knowledge and self-efficacy regarding the bracing protocol of the Ponseti method. In addition, the health practitioners who conducted the educational sessions witnessed an improved ability of all parents to apply the brace as directed, and to recognize and correct improper fit. Completion of the educational program by the parents resulted in immediate improvements in knowledge and skills related to clubfoot bracing. Given that noncompliance to the bracing protocol is the most common cause of clubfoot relapse, these immediate effects of the educational program are promising not only because they encourage proper brace use, but because these immediate improvements have the potential to reduce future rates of clubfoot relapse.
Bayesian analysis of heterogeneous treatment effects for patient-centered outcomes research.
Henderson, Nicholas C; Louis, Thomas A; Wang, Chenguang; Varadhan, Ravi
2016-01-01
Evaluation of heterogeneity of treatment effect (HTE) is an essential aspect of personalized medicine and patient-centered outcomes research. Our goal in this article is to promote the use of Bayesian methods for subgroup analysis and to lower the barriers to their implementation by describing the ways in which the companion software beanz can facilitate these types of analyses. To advance this goal, we describe several key Bayesian models for investigating HTE and outline the ways in which they are well-suited to address many of the commonly cited challenges in the study of HTE. Topics highlighted include shrinkage estimation, model choice, sensitivity analysis, and posterior predictive checking. A case study is presented in which we demonstrate the use of the methods discussed.
Nonoperative treatment of low back pain.
Malanga, G A; Nadler, S F
1999-11-01
Low back pain is a common problem with substantial social and economic issues. Physicians continue to have difficulty managing this condition despite an increased awareness of its magnitude. In addition, there is a misperception about the outcome of patients affected with low back pain; most continue to suffer from pain. We present a nonoperative approach and review various diagnostic and treatment strategies with respect to both scientific and clinical merit. Although many treatment strategies have not been well proved in the scientific literature, thoughtful review of the available information provides a basis for the use of these treatment methods in the patient with refractory pain. This approach can be used in conjunction with existing information to assist clinicians in the management of patients with acute low back pain.

The formation of white spot lesions, or enamel demineralization, around fixed orthodontic attachments is a common complication during and following fixed orthodontic treatment, which marks the result of a successfully completed case. This article is a contemporary review of the risk factors and preventive methods of these orthodontics scars. Preventive programmes must be emphasized to all orthodontic patients. The responsibility of an orthodontist is to minimize the risk of the patient having decalcification as a consequence of orthodontic treatment by educating and motivating the patients for excellent oral hygiene practice. Prophylaxis with topical fluoride application should be implemented: high-fluoride toothpastes, fluoride mouthwashes, gels and varnishes during and after the orthodontic treatment, especially for patients at high risk of caries.
[Panic disorder: clinical phenomena and treatment options].
Sivolap, Yu P
2017-01-01
Panic disorder is a common mental disease with high psychiatric comorbidity. It is considered that a combination of genetic predisposition and a special psychic vulnerability plays a key role in the occurrence of panic disorder. Clinically proven efficacy in the treatment of panic disorder have benzodiazepines, tricyclic antidepressants, monoamine oxidase inhibitors, selective serotonin reuptake inhibitors and selective serotonin and norepinephrine reuptake inhibitors; antidepressants from other pharmaceutical groups are also used. Selective serotonin reuptake inhibitors are the first line medicines in the treatment of panic disorder. Atypical antipsychotics may be used for the therapy augmentation in addition to first line drugs. Psychotherapy is used along with medications, and a combination of pharmacotherapy and cognitive behavioral therapy is the best method of treatment.

Damage to the facial nerve due to trauma from traffic accidents is the second most common cause of paralysis of the facial nerve. The treatments include both pharmacological and non-pharmacological therapy. Acupuncture is a method of treatment that applies evidence-based medical principles and uses anatomy, physiology, and pathology to place needles atcertain acupuncture points. This paper describes a 26-year-old female patient with right-side facial palsy following a traffic accident who had animproved Brackmann’s score after 12 sessions of acupuncture treatment. The acupuncture points were chosen based on Liu Yan’sbrain-clearing needling technique. Acupuncture can shorten healing time and improve the effect of treatment for facial-nerve paralysis.

If we are to find treatments to postpone, reduce the risk of, or completely prevent the clinical onset of Alzheimer disease (AD), we need faster methods to evaluate promising preclinical AD treatments, new ways to work together in support of common goals, and a determination to expedite the initiation and performance of preclinical AD trials. In this article, we note some of the current challenges, opportunities and emerging strategies in preclinical AD treatment. We describe the Collaboration for Alzheimer’s Prevention (CAP)—a convening, harmonizing and consensus-building initiative to help stakeholders advance AD prevention research with rigour, care and maximal impact—and we demonstrate the impact of CAP on the goals and design of new preclinical AD trials.

Analysis of prescription database extracted from standard textbooks of traditional Dai medicine
2012-01-01
Background Traditional Dai Medicine (TDM) is one of the four major ethnomedicine of China. In 2007 a group of experts produced a set of seven Dai medical textbooks on this subject. The first two were selected as the main data source to analyse well recognized prescriptions. Objective To quantify patterns of prescriptions, common ingredients, indications and usages of TDM. Methods A relational database linking the prescriptions, ingredients, herb names, indications, and usages was set up. Frequency of pattern of combination and common ingredients were tabulated. Results A total of 200 prescriptions and 402 herbs were compiled. Prescriptions based on "wind" disorders, a detoxification theory that most commonly deals with symptoms of digestive system diseases, accounted for over one third of all prescriptions. The major methods of preparations mostly used roots and whole herbs. Conclusion The information extracted from the relational database may be useful for understanding symptomatic treatments. Antidote and detoxification theory deserves further research. PMID:22931752
Observations on the treatment of lumbar disk disease in college football players.
Day, A L; Friedman, W A; Indelicato, P A
1987-01-01
Over a 4 year period, 12 college players were treated for diskogenic injury. The most common position affected was down-lineman. Symptoms consisted of low back and/or radicular pain. No players could recall the onset of symptoms relative to football activity; weightlifting was associated with symptoms in three cases. Tentative clinical diagnosis was herniated disk disease. Method of diagnosis in the athletic population is presented along with results of surgical treatment. Percutaneous diskectomy appears to be successful for disk herniations occurring at the L4-5 space or higher.
Seizures and Epilepsy: An Overview for Neuroscientists
Stafstrom, Carl E.; Carmant, Lionel
2015-01-01
Epilepsy is one of the most common and disabling neurologic conditions, yet we have an incomplete understanding of the detailed pathophysiology and, thus, treatment rationale for much of epilepsy. This article reviews the clinical aspects of seizures and epilepsy with the goal of providing neuroscientists an introduction to aspects that might be amenable to scientific investigation. Seizures and epilepsy are defined, diagnostic methods are reviewed, various clinical syndromes are discussed, and aspects of differential diagnosis, treatment, and prognosis are considered to enable neuroscientists to formulate basic and translational research questions.

2018-05-01
A provably time-stable method for solving hyperbolic partial differential equations arising in fluid dynamics on overset grids is presented in this paper. The method uses interface treatments based on the simultaneous approximation term (SAT) penalty method and derivative approximations that satisfy the summation-by-parts (SBP) property. Time-stability is proven using energy arguments in a norm that naturally relaxes to the standard diagonal norm when the overlap reduces to a traditional multiblock arrangement. The proposed overset interface closures are time-stable for arbitrary overlap arrangements. The information between grids is transferred using Lagrangian interpolation applied to the incoming characteristics, although other interpolation schemes could also be used. The conservation properties of the method are analyzed. Several one-, two-, and three-dimensional, linear and non-linear numerical examples are presented to confirm the stability and accuracy of the method. A performance comparison between the proposed SAT-based interface treatment and the commonly-used approach of injecting the interpolated data onto each grid is performed to highlight the efficacy of the SAT method.

Many microbial ecology experiments use sequencing data to measure a community's response to an experimental treatment. In a common experimental design, two units, one control and one experimental, are sampled before and after the treatment is applied to the experimental unit. The four resulting samples contain information about the dynamics of organisms that respond to the treatment, but there are no analytical methods designed to extract exactly this type of information from this configuration of samples. Here we present an analytical method specifically designed to visualize and generate hypotheses about microbial community dynamics in experiments that have paired samples and few or no replicates. The method is based on the Poisson lognormal distribution, long studied in macroecology, which we found accurately models the abundance distribution of taxa counts from 16S rRNA surveys. To demonstrate the method's validity and potential, we analyzed an experiment that measured the effect of crude oil on ocean microbial communities in microcosm. Our method identified known oil degraders as well as two clades, Maricurvus and Rhodobacteraceae, that responded to amendment with oil but do not include known oil degraders. Our approach is sensitive to organisms that increased in abundance only in the experimental unit but less sensitive to organisms that increased in both control and experimental units, thus mitigating the role of "bottle effects".
Morpho-functional implications of myofascial stretching applied to muscle chains: A case study.
Raţ, Bogdan Constantin; Raţă, Marinela; Antohe, Bogdan
2018-03-16
Most lesions of the soft tissues, especially those at the muscle level, are due to the lack of elasticity of the connective tissue and fascia. Stretching is one of the most commonly used methods of treatment for such musculoskeletal issues. This study tracks the effects of stretching on the electromyographic activity of muscle chains, applied to a 24-year-old athlete diagnosed with the Haglund's disease. For the evaluation, we used visual examination and surface electromyography (maximum volumetric isometric contraction). The therapeutic intervention consisted in the application of the static stretching positions, which intended the elongation of the shortened muscle chains. The treatment program had a duration of 2 months, with a frequency of 2 sessions per week and an average duration of 60 minutes. The posterior muscle chains recorded an increase in the EMG activity, while the anterior muscle chains tended to diminish their EMG activity. As a result of the applied treatment, all the evaluated muscle chains recorded a rebalancing of the electromyographic activity, demonstrating the efficiency of stretching as a method of global treatment of muscle chains. By analysing all the data, we have come to the conclusion that static stretching is an effective treatment method for shortened muscle chains.
An evaluation of root resorption after orthodontic treatment.
Thomas, E; Evans, W G; Becker, P
2012-08-01
Root resorption is commonly seen, albeit in varying degrees, in cases that have been treated orthodontically. In this retrospective study the objective was to compare the amount of root resorption observed after active orthodontic treatment had been completed with one of three different appliance systems, namely, Tip Edge, Modified Edgewise and Damon. The sample consisted of pre and post-treatment cephalograms of sixty eight orthodontic cases. Root resorption of the maxillary central incisor was assessed from pre- and post- treatment lateral ce phalograms using two methods. In the first, overall tooth length from the incisal edge to the apex was measured on both pre and post-treatment lateral cephalograms and root resorption was recorded as an actual millimetre loss of tooth length. There was a significant upward linear trend (p = 0.052) for root resorption from the Tip Edge Group to the Damon Group. In the second method root resorption was visually evaluated by using the five grade ordinal scale of Levander and Malmgren (1988). It was found that the majorty of cases in the sample came under Grade 1 and Grade 2 category of root resorption. Statistical evaluation tested the extent of agree ment in this study between visual measurements and actual measurements and demonstrated a significant association (p = 0.018) between the methods.
Recent tuberculosis advances in Latin America

Purpose of review Tuberculosis kills more people than any other infection. Despite advances in diagnostic methods and greater understanding of the reasons for treatment failure, tuberculosis remains common throughout Latin America. Recent findings The impact of HIV and multidrug resistance on tuberculosis control has been enormous. HIV-positive patients may be at 10 times greater risk of multidrug resistant tuberculosis than HIV- negative patients. Hopefully, improved diagnostic techniques will allow more rapid diagnosis of tuberculosis and new colorimetric systems are being developed that will enable expedited drug-sensitivity testing. However, in alarming reports, only 58% of patients were treated with the recommended treatment regime in a Brazilian study, and dropout from treatment in parts of Bolivia was common. Many failings could be combated by rigorous education of patients and physicians. In an encouraging advance, multidrug resistant tuberculosis was successfully treated in a community-based programme, saving an estimated 90% of the cost of hospital-based treatment. An opportunity to identify treatment failure earlier is demonstrated by the finding that 2 months after the initiation of therapy, positive smears were found in only 3% of those whose treatment was successful, but 74% of those whose treatment failed. Summary The importance of inexpensive and widely available drugs to treat HIV and multidrug resistant tuberculosis in Latin America is clear. The need for rapid, affordable tests for tuberculosis diagnosis, and for easy drug sensitivity testing is also evident. Finally, improving treatment success is achievable even in the resource poor setting. PMID:15353958
Iatrosedation: a holistic tool in the armamentarium of anxiety control.
Taneja, Pankaj
2015-01-01
Identifying the causes of dental anxiety by taking a history and carrying out investigations for patients attending for any type of dental procedure, can be time consuming. Common causative factors of dental anxiety can be previous adverse dental experiences, age, temperament or socioeconomic factors. These factors can lead to patients falling into a cycle of dental avoidance and greater treatment need with attendance for symptomatic relief only. Treatment using pharmacological methods such as conscious sedation or general anaesthesia can help overcome these obstacles, however, although a successful treatment outcome may result, how is the patient to gain trust and overcome their anxiety or fear, if they do not learn from the experience? In 1967 Nathan Friedman described a method he termed 'Iatrosedation' consisting of two components, the interview and the clinical encounter. His method relies on the communication skills and behaviour of the practitioner to identify the causes of anxiety or fear and then to provide a bespoke approach to help overcome them. The result can be that the patient not only has successful treatment, but also learns and gains confidence from their experience, as well as gains increased faith in their practitioner.

ABSTRACT Compressive syndromes of the radial nerve have different presentations. There is no consensus on diagnostic and therapeutic methods. The aim of this review is to summarize such methods. Eletronic searches related terms, held in databases (1980-2016): Pubmed (via Medline), Lilacs (via Scielo) and Google Scholar. Through pre-defined protocol, we identified relevant studies. We excluded case reports. Aspects of diagnosis and treatment were synthesized for analysis and tables. Quantitative analyzes were followed by their dispersion variables. Fourteen studies were included. All studies were considered as level IV evidence. Most studies consider aspects of clinical history and provocative maneuvers. There is no consensus on the use of electromyography, and methods are heterogeneous. Studies have shown that surgical treatment (muscle release and neurolysis) has variable success rate, ranging from 20 to 96.5%. Some studies applied self reported scores, though the heterogeneity of the population does not allow inferential analyzes on the subject. few complications reported. Most studies consider the diagnosis of compressive radial nerve syndromes essentially clinical. The most common treatment was combined muscle release and neurolysis, with heterogeneous results. There is a need for comparative studies. Level of Evidence III, Systematic Review. PMID:28642652

The presence of trihalomethanes (THMs) in potable-water sources is an issue of great interest because of the negative impact THMs have on human health. The objective of this study was to correlate the presence of trihalomethanes with more routinely monitored parameters of water quality, in order to facilitate THM control. Water samples taken at various stages of treatment from a water treatment plant were analyzed for the presence of trihalomethanes with the Fujiwara method. The data collected from these determinations were compared with the values obtained for free-residual-chlorine and combined-residual-chlorine levels as well as standard physico-chemical and microbiological indicators such as chemical oxygen demand (by the KMnO4 method), total chlorophyll, conductivity, pH, alkalinity, turbidity, chlorides, sulfates, nitrates, nitrites, phosphates, ammonia, calcium, magnesium, heterotrophic bacteria count, Pseudomonas spp., total and fecal coliforms, and fecal streptococci. The data from these determinations were compiled, and statistical analysis was performed to determine which variables correlate best with the presence and quantity of trihalomethanes in the samples. Levels of THMs in water seem to correlate directly with levels of combined residual chlorine and nitrates, and inversely with the level of free residual chlorine. Statistical analysis with multiple linear regression was conducted to determine the best-fitting models. The models chosen incorporate between two and four independent variables and include chemical oxygen demand, nitrites, and ammonia. These indicators, which are commonly determined during the water treatment process, demonstrate the strongest correlation with the levels of trihalomethanes in water and offer great utility as an accessible method for THM detection and control.

Slipped capital femoral epiphysis (SCFE) can be treated by a variety of methods with the traditional method of in situ pin fixation being most commonly used. More recently, the Modified Dunn (Mod. Dunn) procedure consisting of capital realignment has been popularized as a treatment method for SCFE, particularly for more severe cases. Over the last 5 years, our institution has selectively used this method for more complex cases. The purpose of this article is to evaluate the differences between these 2 treatment methods in terms of avascular necrosis (AVN) rate, reoperation rate, and complication rate. Eighty-eight hips that were surgically treated for SCFE between July 2004 and June 2012 met our inclusion criteria. The in situ fixation group included 71 hips, whereas 17 hips were anatomically reduced with the Mod. Dunn procedure. Loder classification, severity, acuity, complication rate, and reoperation rate were determined for the 2 cohorts. The χ analysis was performed to evaluate the relationship between the treatment method and outcome. As expected, stable slips did well with in situ pinning with no cases of AVN, even in more severe slips. Ten stable slips were treated with the Mod. Dunn approach and 2 (20%) developed AVN. Unstable slips were more difficult to treat with 3 of the 7 hips stabilized in situ developing AVN (43%). Two of the 7 unstable slips treated by the Mod. Dunn procedure developed AVN (29%). The other outcomes studied (reoperation rate and complication rate) were not significantly related to the surgical treatment method (P = 0.732 and 0.261, respectively). In situ pinning remains a safe and predictable method for treatment of stable SCFE with no AVN noted, even in severe slips. Attempts to anatomically reduce stable slips led to severe AVN in 20% of cases, thus this treatment approach should be considered with caution. Treatment of unstable slips remains problematic with high AVN rates noted whether treated by in situ fixation or capital realignment (Mod. Dunn). Level III retrospective comparative study.

Propensity score methods are increasingly being used to estimate causal treatment effects in observational studies. In medical and epidemiological studies, outcomes are frequently time-to-event in nature. Propensity-score methods are often applied incorrectly when estimating the effect of treatment on time-to-event outcomes. This article describes how two different propensity score methods (matching and inverse probability of treatment weighting) can be used to estimate the measures of effect that are frequently reported in randomized controlled trials: (i) marginal survival curves, which describe survival in the population if all subjects were treated or if all subjects were untreated; and (ii) marginal hazard ratios. The use of these propensity score methods allows one to replicate the measures of effect that are commonly reported in randomized controlled trials with time-to-event outcomes: both absolute and relative reductions in the probability of an event occurring can be determined. We also provide guidance on variable selection for the propensity score model, highlight methods for assessing the balance of baseline covariates between treated and untreated subjects, and describe the implementation of a sensitivity analysis to assess the effect of unmeasured confounding variables on the estimated treatment effect when outcomes are time-to-event in nature. The methods in the paper are illustrated by estimating the effect of discharge statin prescribing on the risk of death in a sample of patients hospitalized with acute myocardial infarction. In this tutorial article, we describe and illustrate all the steps necessary to conduct a comprehensive analysis of the effect of treatment on time-to-event outcomes. © 2013 The authors.

Background In South Korea, the number of cases of dental treatment for the disabled is gradually increasing, primarily at regional dental clinics for the disabled. This study investigated pediatric patients at a treatment clinic for the disabled within a university hospital who received dental treatment under general anesthesia. This data could assist those that provide dental treatment for the disabled and guide future treatment directions and new policies. Methods This study was a retrospective analysis of 263 cases in which patients received dental treatment under general anesthesia from January 2011 to May 2016. The variables examined were gender, age, reason for anesthesia, type of disability, time under anesthesia, duration of treatment, type of procedure, treatment details, and annual trends in the use of general anesthesia. Results Among pediatric patients with disabilities who received dental treatment under general anesthesia, the most prevalent age group was 5–8 years old (124 patients, 47.1%), and the primary reason for administering anesthesia was dental anxiety or phobia. The mean time under anesthesia was 132.7 ± 77.6 min, and the mean duration of treatment was 101.9 ± 71.2 min. The most common type of treatment was restoration, accounting for 158 of the 380 treatments performed. Conclusions Due to increasing demand, the number of cases of dental treatment performed under general anesthesia is expected to continue increasing, and it can be a useful method of treatment in patients with dental anxiety or phobia.

Systematic review: the effect on surrogates of making treatment decisions for others.
Wendler, David; Rid, Annette
2011-03-01
Clinical practice relies on surrogates to make or help to make treatment decisions for incapacitated adults; however, the effect of this practice on surrogates has not been evaluated. To assess the effect on surrogates of making treatment decisions for adults who cannot make their own decisions. Empirical studies published in English and listed in MEDLINE, EMBASE, CINAHL, BIOETHICSLINE, PsycINFO, or Scopus before 1 July 2010. Eligible studies provided quantitative or qualitative empirical data, by evaluating surrogates, regarding the effect on surrogates of making treatment decisions for an incapacitated adult. Information on study location, number and type of surrogates, timing of data collection, type of decisions, patient setting, methods, main findings, and limitations. 40 studies, 29 using qualitative and 11 using quantitative methods, provided data on 2854 surrogates, more than one half of whom were family members of the patient. Most surrogates were surveyed several months to years after making treatment decisions, the majority of which were end-of-life decisions. The quantitative studies found that at least one third of surrogates experienced a negative emotional burden as the result of making treatment decisions. The qualitative studies reported that many or most surrogates experienced negative emotional burden. The negative effects on surrogates were often substantial and typically lasted months or, in some cases, years. The most common negative effects cited by surrogates were stress, guilt over the decisions they made, and doubt regarding whether they had made the right decisions. Nine of the 40 studies also reported beneficial effects on a few surrogates, the most common of which were supporting the patient and feeling a sense of satisfaction. Knowing which treatment is consistent with the patient's preferences was frequently cited as reducing the negative effect on surrogates. Thirty-two of the 40 articles reported data collected in the United States. Because the study populations were relatively homogenous, it is unclear whether the findings apply to other groups. In some cases, the effect of making treatment decisions could not be isolated from that of other stressors, such as grief or prognostic uncertainty. Nine of the studies had a response rate less than 50%, and 9 did not report a response rate. Many of the studies had a substantial interval between the treatment decisions and data collection. Making treatment decisions has a negative emotional effect on at least one third of surrogates, which is often substantial and typically lasts months (or sometimes years). Future research should evaluate ways to reduce this burden, including methods to identify which treatment options are consistent with the patient's preferences. National Institutes of Health.

Background Protocol deviations before and after tPA treatment for ischemic stroke are common. It is unclear if patient or hospital factors predict protocol deviations. We examined predictors of protocol deviations and the effects of protocol violations on symptomatic intracerebral hemorrhage. Methods We used data from the INSTINCT trial, a cluster-randomized, controlled trial evaluating the efficacy of a barrier assessment and educational intervention to increase appropriate tPA use in 24 Michigan community hospitals, to review tPA treatments between 2007 and 2010. Protocol violations were defined as deviations from the standard tPA protocol, both before and after treatment. Multi-level logistic regression models were fitted to determine if patient and hospital variables were associated with pre-treatment or post-treatment protocol deviations. Results During the study, 557 patients (mean age 70; 52% male; median NIHSS 12) were treated with tPA. Protocol deviations occurred in 233 (42%) patients: 16% had pre-treatment deviations, 35% had post-treatment deviations, and 9% had both. The most common protocol deviations included elevated post-treatment blood pressure, antithrombotic agent use within 24 hours of treatment, and elevated pre-treatment blood pressure. Protocol deviations were not associated with symptomatic intracerebral hemorrhage, stroke severity, or hospital factors. Older age was associated with pre-treatment protocol deviations (adjusted OR 0.52; 95% confidence interval 0.30-0.92). Pre-treatment deviations were associated with post-treatment deviations (adjusted OR 3.20; 95% confidence interval 1.91-5.35). Conclusions Protocol deviations were not associated with symptomatic intracerebral hemorrhage. Aside from age, patient and hospital factors were not associated with protocol deviations. PMID:26419527

A significant and increasing number of patients receiving radiation therapy present with metal objects close to, or even within, the treatment area, resulting in artifacts in computed tomography (CT) imaging, which is the most commonly used imaging method for treatment planning in radiation therapy. In the presence of metal implants, such as dental fillings in treatment of head-and-neck tumors, spinal stabilization implants in spinal or paraspinal treatment or hip replacements in prostate cancer treatments, the extreme photon absorption by the metal object leads to prominent image artifacts. Although current CT scanners include a series of correction steps for beam hardening, scattered radiation and noisy measurements, when metal implants exist within or close to the treatment area, these corrections do not suffice. CT metal artifacts affect negatively the treatment planning of radiation therapy either by causing difficulties to delineate the target volume or by reducing the dose calculation accuracy. Various metal artifact reduction (MAR) methods have been explored in terms of improvement of organ delineation and dose calculation in radiation therapy treatment planning, depending on the type of radiation treatment and location of the metal implant and treatment site. Including a brief description of the available CT MAR methods that have been applied in radiation therapy, this article attempts to provide a comprehensive review on the dosimetric effect of the presence of CT metal artifacts in treatment planning, as reported in the literature, and the potential improvement suggested by different MAR approaches. The impact of artifacts on the treatment planning and delivery accuracy is discussed in the context of different modalities, such as photon external beam, brachytherapy and particle therapy, as well as by type and location of metal implants.

Assessment and Management of Treatment-Refractory Obsessive-Compulsive Disorder in Children
Bloch, Michael H.; Storch, Eric A.
2015-01-01
OBJECTIVE To review the assessment and treatment of treatment-refractory pediatric obsessive-compulsive disorder (OCD). METHOD A PubMed search was conducted to identify controlled trials in pediatric OCD. Additionally, practice guidelines for the treatment of adults and children were further reviewed for references in treatment-refractory OCD across the lifespan. RESULTS Pharmacotherapy with selective serotonin reuptake inhibitors (SSRIs) and cognitive-behavioral therapy are effective treatments for pediatric OCD. Evidence suggests that CBT is additionally effective even in pediatric patients with refractory OCD symptoms. Antipsychotic augmentation, raising SSRI dosage, and several glutamate-modulating agents have some evidence of efficacy in adults with treatment-refractory OCD but have not been studied in pediatric populations. CONCLUSION Several pharmacological treatment options exist for children with refractory OCD symptoms. However, little evidence-based data exist to guide treatment for our most challenging pediatric OCD patients. Further research is needed to evaluate the efficacy/side-effect profile of commonly used interventions in treatment-refractory pediatric OCD. PMID:25791142
[Diagnosis and treatment of duodenal injury and fistula].
Gong, Kunmei; Guo, Shikui; Wang, Kunhua
2017-03-25
Duodenal injury is a serious abdominal organ injury. Duodenal fistula is one of the most serious complications in gastrointestinal surgery, which is concerned for its critical status, difficulty in treatment and high mortality. Thoracic and abdominal compound closed injury and a small part of open injury are common causes of duodenal injury. Iatrogenic or traumatic injury, malnutrition, cancer, tuberculosis, Crohn's disease etc. are common causes of duodenal fistula, however, there has been still lacking of ideal diagnosis and treatment by now. The primary treatment strategy of duodenal fistula is to determine the cause of disease and its key point is prevention, including perioperative parenteral and enteral nutrition support, improvement of hypoproteinemia actively, avoidance of stump ischemia by excessive separate duodenum intraoperatively, performance of appropriate duodenum stump suture to ensure the stump blood supply, and avoidance of postoperative input loop obstruction, postoperative stump bleeding or hematoma etc. Once duodenal fistula occurs, a simple and reasonable operation can be selected and performed after fluid prohibition, parenteral and enteral nutrition, acid suppression, enzyme inhibition, anti-infective treatment and maintaining water salt electrolyte and acid-base balance. Double tube method, duodenal decompression and peritoneal drainage can reduce duodenal fistula-related complications, and then reduce the mortality, which can save the lives of patients.

Microbiologically influenced corrosion (MIC) is among the common corrosion types for buried and deep-water pipelines that result in costly repair and pipeline failure. Sulfate-reducing bacteria (SRB) are commonly known as the culprit of MIC. The aim of this work is to investigate the performance of combination of ultrasound (US) irradiation and ultraviolet (UV) radiation (known as Hybrid soliwave technique, HyST) at pilot scale to inactivate SRB. The influence of different reaction times with respect to US irradiation and UV radiation and synergistic effect toward SRB consortium was tested and discussed. In this research, the effect of HyST treatment toward SRB extermination and corrosion studies of carbon steel coupon upon SRB activity before and after the treatment were performed using weight loss method. The carbon steel coupons immersed in SRB sample were exposed to HyST treatment at different time of exposure. Additionally, Field Emission Scanning Electron Microscopy coupled with Energy Dispersive X-ray Spectroscopy were used to investigate the corrosion morphology in verifying the end product of SRB activity and corrosion formation after treatment. Results have shown that the US irradiation treatment gives a synergistic effect when combined with UV radiation in mitigating the SRB consortium.
Brain Stimulation and the Role of the Right Hemisphere in Aphasia Recovery.
Turkeltaub, Peter E
2015-11-01
Aphasia is a common consequence of left hemisphere stroke and causes a disabling loss of language and communication ability. Current treatments for aphasia are inadequate, leaving a majority of aphasia sufferers with ongoing communication difficulties for the rest of their lives. In the past decade, two forms of noninvasive brain stimulation, repetitive transcranial magnetic stimulation and transcranial direct current stimulation, have emerged as promising new treatments for aphasia. The most common brain stimulation protocols attempt to inhibit the intact right hemisphere based on the hypothesis that maladaptive activity in the right hemisphere limits language recovery in the left. There is now sufficient evidence to demonstrate that this approach, at least for repetitive transcranial magnetic stimulation, improves specific language abilities in aphasia. However, the biological mechanisms that produce these behavioral improvements remain poorly understood. Taken in the context of the larger neurobiological literature on aphasia recovery, the role of the right hemisphere in aphasia recovery remains unclear. Additional research is needed to understand biological mechanisms of recovery, in order to optimize brain stimulation treatments for aphasia. This article summarizes the current evidence on noninvasive brain stimulation methods for aphasia and the neuroscientific considerations surrounding treatments using right hemisphere inhibition. Suggestions are provided for further investigation and for clinicians whose patients ask about brain stimulation treatments for aphasia.

Melasma is a common acquired pigmentary disorder marked by irregular hyperpigmented macules or patches and most commonly occurs in women of darker skin color. It is a chronic often-relapsing condition that causes negative psychosocial effects in those affected. Current treatments such as hydroquinone, kojic acid, and retinoids, among others, demonstrate variable efficacy and side-effect profiles. We conducted a comprehensive literature review examining the use of tranexamic acid (TA), a well-known anti-fibrinolytic agent, in the treatment of melasma. TA delivered orally, topically, and through physical methods works via the inhibition of ultraviolet (UV)-induced plasmin activity in keratinocytes. Predefined search terms were entered into PubMed. Articles were then independently screened by two authors to include only those written in the English language and relating to human subjects with at least mild melasma. The search identified 28 articles, 15 of which met the criteria for full review. The review revealed that TA treatment for melasma is equally effective or more effective than other standard therapies and may induce fewer side effects. Our comprehensive review suggests that TA may be a promising treatment option for melasma because of its demonstrated effectiveness alone and in combination with other modalities as well as its limited side-effect profile.

Background. Occasional cases of viral escape in cerebrospinal fluid (CSF) despite suppression of plasma human immunodeficiency virus type 1 (HIV-1) RNA have been reported. We investigated CSF viral escape in subjects treated with commonly used antiretroviral therapy regimens in relation to intrathecal immune activation and central nervous system penetration effectiveness (CPE) rank. Methods. Sixty-nine neurologically asymptomatic subjects treated with antiretroviral therapy >6 months and plasma HIV-1 RNA <50 copies/mL were cross-sectionally included in the analysis. Antiretroviral therapy regimens included efavirenz, lopinavir/ritonavir or atazanavir/ritonavir combined with tenofovir, abacavir, or zidovudine and emtricitabine or lamivudine. HIV-1 RNA was analyzed with real-time polymerase chain reaction assays. Neopterin was analyzed by enzyme-linked immunosorbent assay. Results. Seven (10%) of the 69 subjects had detectable CSF HIV-1 RNA, in median 121 copies/mL (interquartile range, 54–213 copies/mL). Subjects with detectable CSF virus had significantly higher CSF neopterin and longer duration of treatment. Previous treatment interruptions were more common in subjects with CSF escape. Central nervous system penetration effectiveness rank was not a significant predictor of detectable CSF virus or CSF neopterin levels. Conclusions. Viral escape in CSF is more common than previously reported, suggesting that low-grade central nervous system infection may continue in treated patients. Although these findings need extension in longitudinal studies, they suggest the utility of monitoring CSF responses, as new treatment combinations and strategies modify clinical practice.

Study Objectives: Describe common symptoms, comorbidities, functional limitations, and treatment responsiveness among patients with narcolepsy. Investigate the effect of pediatric onset of narcolepsy symptoms on time to diagnosis of narcolepsy and presence of comorbid depression. Methods: Cross-sectional survey of 1,699 people in the United States with self-reported diagnosis of narcolepsy. We utilized mixed-methods data analyses to report study findings. Results: Most participants reported receiving a diagnosis of narcolepsy more than 1 y after symptom onset. We found that the strongest predictor of this delayed diagnosis was pediatric onset of symptoms (odds ratio = 2.4, p < 0.0005). Depression was the most common comorbidity but we detected no association with pediatric onset of narcolepsy symptoms. Overall, participants reported that fatigue and cognitive difficulties were their most burdensome symptoms in addition to sleepiness and cataplexy. The majority of participants reported residual daytime fatigue and/or sleepiness despite treatment. Most participants reported they could not perform at work or school as well as they would like because of narcolepsy symptoms. Conclusions: This study provides unique insight into the narcolepsy disease experience. The study quantifies the problem of diagnostic delay for narcolepsy patients in the United States and highlights that symptoms are more likely to be missed if they develop before 18 y of age. These results suggest that narcolepsy awareness efforts should be aimed at parents, pediatric health care providers, school professionals, and children/adolescents themselves. Disease burden is high because of problems with fatigue, cognition, and persistence of residual symptoms despite treatment.

Objective: Carcinoma of the uterine cervix is either the first or second most common malignancy in Indian women, depending on the registry. Tumor growth and metastasis primarily are determined by angiogenesis and parameters of the molecular environment including extracellular matrix elements, growth factors and cytokines. Effects of chemo-irradiation on biomarkers like vascular endothelial growth factor (VEGF), angiopoietin-2 (Ang-2) and laminin in patients with carcinoma cervix therefore need to be explored. Methods: Circulatory and mRNA levels of VEGF, Ang-2 and laminin in patients with stage III carcinoma cervix (n=40) were compared with those of normal healthy women (n=20). Measurement was prior to treatment, and after chemotherapy and teleradiation, using high sensitivity ELISA kits and Q-PCR. Clinical response was evaluated as per WHO criteria and was assessed for correlation with the biochemical markers. Results: Levels of all the studied molecules were significantly (p<0.001) higher in patients than in controls. After treatment significant decline (p<0.001) was noted. Out of 40 patients, 33 were complete responders and 7 were non-responders on clinical assessment. On comparison of before and after treatment levels of these molecules complete responders showed significant decline whereas non-responders showed non-significant decrease. Follow-up of the responders for 3 years, revealed 28 of 33 patients to still be disease free, the other 5 demonstrating recurrence. Conclusions: Higher levels of angiogenic factors along with laminin indicate roles played in disease progression aiding angiogenesis. These markers may serve as useful tools in post treatment disease mapping, for which available imaging methods may not provide a true picture. Creative Commons Attribution License

Atlantic salmon farming is one of the largest aquaculture industries in the world. A major problem in salmon farms is the sea louse ectoparasite Lepeophtheirus salmonis, which can cause stress, secondary infection and sometimes mortality in the salmon host. Sea lice have substantial impacts on farm economics and potentially nearby wild salmonid populations. The most common method of controlling sea louse infestations is application of chemicals. However, most farming regions worldwide have observed resistance to the small set of treatment chemicals that are available. Despite this, there has been little investigation of treatment strategies for managing resistance in aquaculture. In this article, we compare four archetypical treatment strategies inspired by agriculture, where the topic has a rich history of study, and add a fifth strategy common in aquaculture. We use an agent-based model (ABM) to simulate these strategies and their varying applications of chemicals over time and space. We analyse the ABM output to compare how the strategies perform in controlling louse abundance, number of treatments required and levels of resistance in the sea louse population. Our results indicated that among the approaches considered applying chemicals in combination was the most effective over the long term. © 2016 The Author(s).

A simple project is described for introducing students to some experimental procedures commonly used to measure the effects of thermal treatment on synthetic polymers. The thermally induced changes that occur in the commodity polymers low-density polyethylene (LDPE), poly(ethylene terephthalate) (PET), and poly(vinyl chloride) (PVC) are examined as a function of the time of thermal treatment in an air-circulating oven. In particular, simple procedures are described for determining (i) the polymer hydroperoxide (POOH) content and carbonyl index (CI) of LDPE, (ii) the extent of whitening of PET, and (iii) the extent of discoloration or "yellowing" of PVC, all of which change during thermal treatment. The POOH content of LDPE is determined using a ferrometric method and the CI of this polymer is measured by both Fourier transform infrared spectroscopy and a staining technique involving 2,4-dinitrophenylhydrazine. The thermal oxidation of LDPE and the kinetics of formation of its POOH and carbonyl species are discussed with reference to the accepted mechanism for the autooxidation of polyolefins. The whitening of PET and the yellowing of PVC during thermal treatment are explained by means of a crystallization process and a "zip" dehydrochlorination reaction, respectively.

Summary Background Acute hepatitis C has variable modes of presentation and frequently results in chronic infection. Its optimal management has yet to be defined. Aims To establish natural history and complications of treatment of acute hepatitis C. Methods Data from all patients presenting with acute hepatitis C to the National Institutes of Health between 1994 and 2007 were reviewed. Results Twenty-five patients were identified. Symptoms were reported by 80% and jaundice by 40%. Aminotransferase levels and HCV RNA levels fluctuated greatly; 18% of patients were intermittently negative for HCV RNA. Five patients recovered spontaneously whereas 20 developed chronicity or received interferon-based therapy during the acute phase. Among 15 patients treated during the acute phase with peginterferon with or without ribavirin for 24 weeks, all became HCV RNA negative within 4 to 8 weeks, and all except two (HIV-positive) achieved a sustained virological response. Side effects (particularly psychiatric) were common and limited treatment in 30%. Conclusion Thus, among 25 patients with acute HCV infection, fluctuating illness was common and spontaneous recovery occurred in only 20%. Antiviral treatment with a 24-week course of peginterferon and ribavirin was highly effective but marked by frequent and severe side effects. PMID:21198704

Background: The nail gun is a commonly utilized tool in carpentry and construction. When used properly with appropriate safety precautions, it can facilitate production and boost efficiency; however, this powerful tool also has the potential to cause serious injury. The most common site of nail-gun injuries in both industrial and nonoccupational settings is the hand. Materials and Methods: We report on two patients with nail-gun injuries to the hand. A review of the literature and discussion of clinical evaluation and treatment of nail-gun injuries to the hand are presented. Results: Two patients present with soft tissue injuries to the hand with the nail embedded and intact at the injury site. Operative removal of the nail and wound care resulted in successful treatment in both cases. Nail-gun injuries to the hand vary in severity on the basis of the extent of structural damage. Treatment is based on the severity of injury and the presence and location of barbs on the penetrating nail. Conclusion: Healthcare providers must understand and educate patients on the prevention mechanics of nail-gun injuries. Nail-gun injuries to the hand necessitate appropriate evaluation techniques, understanding of surgical management versus nonsurgical management, and awareness of potential pitfalls in treatment.

Henoch-Schonlein purpura (HSP) is an immune-mediated systemic vasculitis generally found in children. The standard manifestations of HSP are palpable purpura, arthritis, abdominal pain, and renal complications. Although less common, there are significant urological manifestations associated with HSP. The primary objective of this review is to encourage better understanding and management of HSP by emphasizing the common and rare manifestations of HSP, how they are diagnosed, and the latest treatment options for mild to severe complications. Medline searches of HSP and its urological manifestations were conducted along with searches on current diagnostic and treatment methods. Urological manifestations of HSP involve the kidney, ureter, bladder, prostate, scrotum, testicle, and penis. Diagnosis and management of HSP are not always clear due to differential diagnosis and diversity of symptom presentation. Treatment for HSP is mainly supportive and includes use of nonsteroidal anti-inflammatory drugs for pain relief. In more severe cases, glucocorticoids, methylprednisolone, plasmapheresis, and peritoneal and hemodialysis are reported successful. It is important to note different symptoms of HSP in order to distinguish HSP from other diseases. Early diagnosis may prevent severe complications. Treatment options vary from conservative to invasive depending on the severity of the disease and time frame of diagnosis. PMID:26889120

Treatment research is sometimes criticised as lacking in clinical relevance, and one potential source of this friction is a disconnection between statistical significance and what clinicians regard to be a meaningful difference in outcomes. This report demonstrates a novel methodology for estimating what substance abuse practitioners regard to be clinically important differences. To illustrate the estimation method, we surveyed 50 substance abuse treatment providers participating in the National Institute on Drug Abuse (NIDA) Clinical Trials Network. Practitioners identified thresholds for clinically meaningful differences on nine common outcome variables, indicated the size of effect that would justify their learning a new treatment method and estimated current outcomes from their services. Clinicians judged a difference between two treatments to be meaningful if outcomes were improved by about 10 - 12 points on the percentage of patients totally abstaining, arrested for driving while intoxicated, employed or having abnormal liver enzymes. A 5 percentage-point reduction in patient mortality was regarded as clinically significant. On continuous outcome measures (such as percentage of days abstinent or drinks per drinking day), practitioners judged an outcome to be significant when it doubled or halved the base rate. When a new treatment meets such criteria, practitioners were interested in learning it. Effects that are statistically significant in clinical trials may be unimpressive to practitioners. Clinicians' judgements of meaningful differences can inform the powering of clinical trials.

Seagrass meadows near population centers are subject to frequent disturbance from vessel groundings. Common seagrass restoration methods include filling excavations and applying fertilizer to encourage seagrass recruitment. We sampled macrophytes, soil structure, and macroinvertebrate infauna at unrestored and recently restored vessel grounding disturbances to evaluate the effects of these restoration methods on seagrass ecosystem structure. After a year of observations comparing filled sites to both undisturbed reference and unrestored disturbed sites, filled sites had low organic matter content, nutrient pools, and primary producer abundance. Adding a nutrient source increased porewater nutrient pools at disturbed sites and in undisturbed meadows, but not at filled sites. Environmental predictors of infaunal community structure across treatments included soil texture and nutrient pools. At the one year time scale, the restoration methods studied did not result in convergence between restored and unrestored sites. Particularly in filled sites, soil conditions may combine to constrain rapid development of the seagrass community and associated infauna. Our study is important for understanding early recovery trajectories following restoration using these methods. Published by Elsevier Ltd.

The goal of this research is to produce oleoresin from basil leaves (Ocimum canum) by using soxhletation method and ethyl acetate as solvent. Basil commonly used in culinary as fresh vegetables. Basil contains essential oils and oleoresin that are used as flavouring agent in food, in cosmetic and ingredient in traditional medicine. The extraction method commonly used to obtain oleoresin is maceration. The problem of this method is many solvents necessary and need time to extract the raw material. To resolve the problem and to produce more oleoresin, we use soxhletation method with a combination of extraction time and ratio from the material with a solvent. The analysis consists of yield, density, refractive index, and essential oil content. The best treatment of basil leaves oleoresin extraction is at ratio of material and solvent 1:6 (w / v) for 6 hours extraction time. In this condition, the yield of basil oleoresin is 20.152%, 0.9688 g/cm3 of density, 1.502 of refractive index, 15.77% of essential oil content, and the colour of oleoresin product is dark-green.

We investigated the prevalence and persistence of Escherichia coli strains in four sewage treatment plants (STPs) in a subtropical region of Queensland, Australia. In all, 264 E. coli strains were typed using a high-resolution biochemical fingerprinting method and grouped into either a single or a common biochemical phenotype (S-BPT and C-BPT, respectively). These strains were also tested for their phylogenetic groups and 12 virulence genes associated with intestinal and extraintestinal E. coli strains. Comparison of BPTs at various treatment stages indicated that certain BPTs were found in two or all treatment stages. These BPTs constituted the highest proportion of E. coli strains in each STP and belonged mainly to phylogenetic group B2 and, to a lesser extent, group D. No virulence genes associated with intestinal E. coli were found among the strains, but 157 (59.5%) strains belonging to 14 C-BPTs carried one or more virulence genes associated with uropathogenic strains. Of these, 120 (76.4%) strains belonged to seven persistent C-BPTs and were found in all four STPs. Our results indicate that certain clonal groups of E. coli with virulence characteristics of uropathogenic strains can survive the treatment processes of STPs. These strains were common to all STPs and constituted the highest proportion of the strains in different treatment tanks of each STP. PMID:20622128

To review the literature on retrograde periimplantitis symptoms, risk factors, and treatment methods and to propose a decision-making tree of retrograde periimplantitis management. An electronic literature search was conducted on the MEDLINE and EMBASE databases for articles published between 1990 and 2015. Clinical human studies in the English language were included. The search resulted in 44 case reports published by 27 authors. The average time of the diagnosis of the pathology was found to be 26.07 weeks after implant placement (SD ± 39.7). Fistula formation was found to be the most common clinical symptom, statistically significantly more often occurring in the maxilla (P = 0.04). A negative correlation was found between pain and the adjacent tooth with incomplete endodontic treatment/endodontic pathology (r = -0.4; P = 0.009) and a positive correlation between the later risk factor and implant removal (r = 0.3; P = 0.028). Regenerative treatment (45.2% of the cases) or implant removal (35.7% of the cases) was the most common treatment techniques used. A decision-making tree of retrograde periimplantitis management is suggested. The etiology of retrograde periimplantitis is most often infectious. A decision-making tree aimed at managing patients with retrograde periimplantitis according to the possible etiology and symptoms of the disease can be a useful tool in the treatment of the pathology.

Although cervical radiculopathy is very common, there is no standard treatment for this condition, with little high-level evidence available to guide the treatment choice. Thus, this study aimed to review the current data on the management of cervical radiculopathy; and, further, to establish a new Chinese clinical consensus of the treatments for cervical radiculopathy using the Delphi method. First, a systematic review of the previously established treatment guidelines and of articles related to cervical radiculopathy was conducted to establish a protocol for the clinical consensus of the treatment for cervical radiculopathy. Second, from February 2012 to June 2014, we performed a modified Delphi survey in which the current professional opinions from 30 experienced experts, representing almost all of the Chinese provinces, were gathered. Three rounds were performed, and consensus was defined as ≥70% agreement. Consensus of the treatments for cervical radiculopathy was reached on seven aspects, including the proportion of patients requiring only non-surgical therapies; the effectiveness of neck immobilization, physiotherapy, pharmacologic treatment; surgical indications; contraindications; surgery. The modified Delphi study conducted herein reached a consensus concerning several treatment issues for cervical radiculopathy. In the absence of high-level evidence, at present, these expert opinion findings will help guide health care providers to define the appropriate treatment in their regions. Items with no consensus provide excellent areas for future research.

PurposeTo evaluate the predictors of toxicity of drug-eluting beads loaded with irinotecan (DEBIRI) in the treatment of hepatic malignancies.Materials and MethodsA total of 330 patients were enrolled in a prospective, open-label, multicenter, multinational, single-arm study administering two types of drug-eluting beads (DEBIRI and drug-eluting beads loaded with doxorubicin). Complications were graded by Cancer Therapy Evaluation Program's Common Terminology Criteria for Adverse Events (CTCAE) version 3.0. All events requiring additional physician treatment or requiring extended hospital stay or readmission within 30 days were included.ResultsA total of 109 patients received 187 DEBIRI treatments (range 1 to 5 per patient). The most commonmore » histology was metastatic colorectal cancer in 76% of patients, cholangiocarcinoma in 7% of patients, and other metastatic disease in 17% of patients. There were 35 patients (19%) with irinotecan treatments who sustained 158 treatment-related adverse events, with the median CTCAE event grade being CTCAE grade 2 (range 1 to 5). The most common adverse events were postembolic symptoms (42%). Multivariate analysis identified pretreatment and treatment-related risk factors as follows: lack of pretreatment with hepatic arterial lidocaine (p = 0.005), {>=}3 treatments (p = 0.05), achievement of complete stasis (p = 0.04), treatment with >100 mg DEBIRI in 1 treatment (p = 0.03), and bilirubin >2.0 {mu}g/dl with >50% liver involvement (p = 0.05). These factors were predictive of adverse events and significantly greater hospital length of stay.ConclusionsDEBIRI is safe when appropriate technique and treatment are used. Adverse events can be predicted based on pretreatment- and treatment-related factors, and their occurrence can become part of the informed consent process. Continued standardization of this treatment will lead to fewer adverse events and improved patient quality of life.« less

Purpose To review treatments for osteoarthritis of the knee (OAK) received by patients across five European countries, and to obtain patients’ perceptions and willingness to pay for current treatments. Patients and methods A prospective, internet-based, double-blind survey of adults with OAK was conducted in France, Germany, Italy, Spain, and the United Kingdom. The questionnaire included questions about diagnosis, treatment history, and perceptions of OAK treatments, followed by a discrete choice-based conjoint exercise to identify preferred attributes of OAK treatments, evaluating 14 sets of four unbranded products. Results Two thousand and seventy-three patients with self-reported OAK completed the survey; 17.4% of patients rated their knee pain as drastically affecting their ability to perform normal daily activities, and 39.3% of employed patients reported that they had lost work time because of OAK. The most common treatments were exercise (69.7%), physical therapy (68.2%), and nonprescription oral pain medication (73.9%). Treatments perceived as most effective were: viscosupplement injections (74.1%), narcotics (67.8%), and steroid injection (67.6%). Patient co-pay, duration of pain relief, and type of therapy exhibited the largest impact on patient preference for OAK treatments. The average patient was willing to pay €35 and €64 more in co-pay for steroid and viscosupplement injections, respectively, over the cost of oral over-the-counter painkillers (per treatment course, per knee) (each P<0.05). Conclusion OAK is a debilitating condition that affects normal daily activities. In general, treatments most commonly offered to patients are not those perceived as being the most effective. Patients are willing to pay a premium for treatments that they perceive as being more effective and result in longer-lasting pain relief, and those that can be administered with fewer visits to a physician.

Although the Achilles tendon (AT) is the strongest tendon in the human body, rupture of this tendon is one of the most common sports injuries in the athletic population. Despite numerous nonoperative and operative methods that have been described, there is no universal agreement about the optimal management strategy of acute total AT ruptures. The management of AT ruptures should aim to minimize the morbidity of the injury, optimize rapid return to full function, and prevent complications. Since endoscopy-assisted percutaneous AT repair allows direct visualization of the synovia and protects the paratenon that is important in biological healing of the AT, this technique becomes a reasonable treatment option in AT ruptures. Furthermore, Achilles tendoscopy technique may decrease the complications about the sural nerve. Also, early functional postoperative physiotherapy following surgery may improve the surgical outcomes. PMID:24198562

The Finnish dairy herd recording system maintains production and health records of cows and herds. Veterinarians and farmers register veterinary treatments in the system. Milk samples for microbiological analysis are routinely taken from mastitic cows. The laboratory of the largest dairy company in Finland, Valio Ltd., analyzes most samples using real-time PCR. This study addressed pathogen-specific microbiological data and treatment and culling records, in combination with cow and herd characteristics, from the Finnish dairy herd recording system during 2010-2012. The data derived from 240,067 quarter milk samples from 93,529 dairy cows with mastitis; 238,235 cows from the same herds served as the control group. No target pathogen DNA was detected in 12% of the samples. In 49% of the positive samples, only one target species and in 19%, two species with one dominant species were present. The most common species in the samples with a single species only were coagulase-negative staphylococci (CNS) (43%), followed by Staphylococcus aureus (21%), Streptococcus uberis (9%), Streptococcus dysgalactiae (8%), Corynebacterium bovis (7%), and Escherichia coli (5%). On average, 36% of the study cows and 6% of the control cows had recorded mastitis treatments during lactation. The corresponding proportions were 16 and 6% at drying-off. For more than 75% of the treatments during lactation, diagnosis was acute clinical mastitis. In the milk samples from cows with a recorded mastitis treatment during lactation, CNS and S. aureus were most common, followed by streptococci. Altogether, 48% of the cows were culled during the study. Mastitis was reported as the most common reason to cull; 49% of study cows and 18% of control cows were culled because of mastitis. Culling was most likely if S. aureus was detected in the milk sample submitted during the culling year. The PCR test has proven to be an applicable method also for large-scale use in bacterial diagnostics. In the present study, microbiological diagnosis was unequivocal in the great majority of samples where a single species or two species with one dominating were detected. Coagulase-negative staphylococci and S. aureus were the most common species. S. aureus was also the most common pathogen among the culled cows, which emphasizes the importance of preventive measures.

Background Acute sore throat is commonly associated with viral infections. Consumers typically rely on over-the-counter treatments and other remedies to treat symptoms; however, limited information is available regarding consumer perceptions of sore throat or treatment needs. The aim of this study was to investigate perceptions of throat discomfort and how these influence attitudes and consumer behaviour with regard to treatment. Methods Online consumer surveys were completed by participants invited by email between 2003 and 2004 in four markets: the UK, France, Poland, and Malaysia. The questionnaire consisted of 24 questions that covered key issues surrounding throat discomfort including incidence in the past 12 months, causes, severity, effects on functionality and quality of life, actions taken to relieve throat discomfort, the efficacy of these approaches and the reasons behind using specific products. Results In total, 6465 men and women aged ≥18 years were surveyed, identifying 3514 participants who had suffered throat discomfort/irritation in the past 12 months (response rate of 54%). These participants completed the full survey. The breakdown of throat discomfort sufferers was: UK, 912; France, 899; Poland, 871; Malaysia, 832. A high proportion of respondents experienced one or more instances of throat discomfort in the previous 12 months, with an overall incidence of 54%. Infections including the common cold/influenza and other bacteria/viruses were commonly perceived causes of throat discomfort (72% and 46%, respectively). Physical and environmental factors were also perceived to be causative, including airborne pollution (28%), smoking (23%), and air conditioning (31%). Symptoms perceived to be caused by an infection were associated with a higher degree of suffering (mean degree of suffering for bacteria/virus and common cold/influenza; 3.4 and 3.0, respectively). Medicinal products were used for all perceived causes, but more commonly for sore throats thought to be caused by infections. Cold drinks were used more often for symptoms thought to be due to physical and environmental causes. Conclusions Not all throat discomfort is the same, as demonstrated by the range of perceived causes and the emotional and physical symptoms experienced. Patient expectations regarding treatment of throat discomfort differs and treatments should be tailored by pharmacists to suit the cause. PMID:22883470

There have been some reports on the efficacy and tolerability of an oral itraconazole (ITCZ) solution as prophylaxis for fungal infection in patients with hematological malignancies. However, there are some cases where the bitter taste of oral ITCZ solution leads to an interruption of administration because the patient refuses to take this medicine. Therefore, we prospectively investigated the pharmacokinetics and promotion of treatment adherence in patients taking oral ITCZ solution mixed with a beverage. Compared with the responses of patients taking oral ITCZ solution with water, the taste of the agent was improved significantly when mixed with orange juice, although the plasma concentration of the agent did not differ between the two groups. Using this method, we can expect an improvement in treatment adherence and this method can easily be applied in clinical practice. This method is highly useful and should become common knowledge.

Because black rice is rich in antioxidants, appropriate methods of post-harvest treatment are necessary for maintaining these bioactive phytochemicals. Drying methods, storage temperatures, storage duration, and packaging methods affected the contents of some bioactive compounds in the two varieties of Thai black rice used in this research. Sun drying reduces the loss of anthocyanins and γ-oryzanols more than does hot air drying. Glutinous black rice stored as paddy at cool room temperature retains more anthocyanins, γ-oryzanols, and vitamin E than does paddy stored at room temperature. Nylon/LLDPE pouches containing N2 are the most suitable packaging for preserving the key aroma compound 2-acetyl-1-pyrroline (2AP), total phenolic, and anthocyanin contents of unpolished aromatic black rice. These pouches also retard the formation of some common off-flavor compounds. Copyright © 2016 Elsevier Ltd. All rights reserved.

Image fusion is a process of combining information from multiple sensors. It is a useful tool implemented in the treatment planning programme of Gamma Knife Radiosurgery. In this paper we evaluate advanced image fusion algorithms for Matlab platform and head images. We develop nine level grayscale image fusion methods: average, principal component analysis (PCA), discrete wavelet transform (DWT) and Laplacian, filter - subtract - decimate (FSD), contrast, gradient, morphological pyramid and a shift invariant discrete wavelet transform (SIDWT) method in Matlab platform. We test these methods qualitatively and quantitatively. The quantitative criteria we use are the Root Mean Square Error (RMSE), the Mutual Information (MI), the Standard Deviation (STD), the Entropy (H), the Difference Entropy (DH) and the Cross Entropy (CEN). The qualitative are: natural appearance, brilliance contrast, presence of complementary features and enhancement of common features. Finally we make clinically useful suggestions.

Tuberculosis (TB) is an ancient disease, but not a disease of the past. The increasing prevalence of drug-resistant strains of Mycobacterium tuberculosis, the causative agent of TB, demands new measures to combat the situation. Rapid and accurate detection of the pathogen, and its drug susceptibility pattern, is essential for timely initiation of treatment, and ultimately, control of the disease. Molecular-based methods offer a great chance to improve detection of drug-resistant TB; however, their development and usage should be accompanied with a profound understanding of drug resistance mechanisms and circulating M. tuberculosis strains in specific settings, as otherwise, the usefulness of such tests may be limited. This review gives an overview of the history of TB treatment and drug resistance, drug resistance mechanisms for the most commonly used drugs and molecular methods designed to detect drug-resistant strains.

2013-01-01
Spectral fingerprinting, as a method of discriminating between plant cultivars and growing treatments for a common set of broccoli samples, was compared for six analytical instruments. Spectra were acquired for finely powdered solid samples using Fourier transform infrared (FT-IR) and Fourier transform near-infrared (NIR) spectrometry. Spectra were also acquired for unfractionated aqueous methanol extracts of the powders using molecular absorption in the ultraviolet (UV) and visible (VIS) regions and mass spectrometry with negative (MS−) and positive (MS+) ionization. The spectra were analyzed using nested one-way analysis of variance (ANOVA) and principal component analysis (PCA) to statistically evaluate the quality of discrimination. All six methods showed statistically significant differences between the cultivars and treatments. The significance of the statistical tests was improved by the judicious selection of spectral regions (IR and NIR), masses (MS+ and MS−), and derivatives (IR, NIR, UV, and VIS). PMID:21352644
Intracardiac Shunting and Stroke in Children: A Systematic Review
Dowling, Michael M.; Ikemba, Catherine M.
2017-01-01
In adults, patent foramen ovale or other potential intracardiac shunts are established risk factors for stroke via paradoxical embolization. Stroke is less common in children and risk factors differ. The authors examined the literature on intracardiac shunting and stroke in children, identifying the methods employed, the prevalence of detectible intracardiac shunts, associated conditions, and treatments. PubMed searches with keywords related to intracardiac shunting and stroke in children identified articles of interest. Additional articles were identified via citations in these articles or in reviews. The authors found that studies of intracardiac shunting in children with stroke are limited. No controlled studies were identified. Detection methods vary and the prevalence of echocardiographically detectible intracardiac shunting appears lower than reported in adults and autopsy studies. Defining the role of intracardiac shunting in pediatric stroke will require controlled studies with unified detection methods in populations stratified by additional risk factors for paradoxical embolization. Optimal treatment is unclear. PMID:21212453
Estimation of group means when adjusting for covariates in generalized linear models.
Qu, Yongming; Luo, Junxiang
2015-01-01
Generalized linear models are commonly used to analyze categorical data such as binary, count, and ordinal outcomes. Adjusting for important prognostic factors or baseline covariates in generalized linear models may improve the estimation efficiency. The model-based mean for a treatment group produced by most software packages estimates the response at the mean covariate, not the mean response for this treatment group for the studied population. Although this is not an issue for linear models, the model-based group mean estimates in generalized linear models could be seriously biased for the true group means. We propose a new method to estimate the group mean consistently with the corresponding variance estimation. Simulation showed the proposed method produces an unbiased estimator for the group means and provided the correct coverage probability. The proposed method was applied to analyze hypoglycemia data from clinical trials in diabetes. Copyright © 2014 John Wiley & Sons, Ltd.

2015-06-15
Ever since its introduction as a diagnostic imaging modality over 30 years ago, the radiation therapy community has acknowledged the utility of MR imaging as a tool for not only improved visualization of the target volume but also for demarcation of adjacent organs at risk. However, the adaptation of MR imaging in radiation oncology has, until recently been slow due in large part to the inability to image radiation therapy patients in their treatment position. With the introduction of so-called wide bore high field MR scanners, multi element flexible receive only RF coils, high performance imaging gradients and a rangemore » of volumetric imaging sequences it is now possible to obtain both high resolution and high signal-to-noise ratio images of in-treatment radiation therapy patients within clinically feasible imaging times. As a Result, there is renewed interest in the use of MR imaging for radiation oncology treatment planning that is being translated into physical siting and integration of these systems into radiation oncology departments. As MR imaging expands into the radiation oncology domain there is a significant and unmet need for radiation therapy physicists to become educated regarding the strengths, limitations and technical challenges associated with MR imaging. The purpose of this presentation is to address this need by providing an educational overview of the techniques and challenges associated with MR imaging of patients for radiation therapy treatment planning. As such this presentation will: 1) describe the fundamental differences between imaging of patients for diagnostic and therapeutic purposes (i.e. radiation therapy planning), 2) describe most commonly used imaging sequences and contrasts for identification of disease for radiation planning, 3) identify the most common sources of image distortion and techniques to reduce their effect on spatial fidelity of the MR data, 4) describe the effects of motion and methods to quantify/correct it, and 5) identify emergent techniques for performing MR only treatment simulation. Upon completion attendees will have a working understanding of the basic methodologies associated with MR imaging in radiation oncology, the unique technical challenges imposed by MR imaging in the treatment position and techniques to address these. Learning Objectives: 1. Understand the differences between MR imaging for diagnostic imaging and for radiation therapy planning. 2. Identify the most common sources of distortion and artifacts and simple methods to correct them. 3. Understand the challenges with MR imaging in the therapy treatment position and appropriate techniques to address them.« less

Fluctuations of good days and bad days-in physical symptoms and emotional states-are common for individuals with chronic illness. This pilot study examines these fluctuations during bodywork treatment. We analyzed changes in daily self-reports over a period of five months for five individuals who received weekly treatments of Rosen Method Bodywork (RMB), which uses touch and words to enhance body awareness of physical sensations and emotional states. Five subjects (aged 31-56) who had chronic low back pain (CLBP) received 16 weekly treatments given by three experienced RMB practitioners. Pre- and posttreatment assessments covered demographics, disability, and pain. Clients also completed daily bedtime assessments of pain, fatigue, emotional state, and sense of control during the entire treatment period. All clients reported reductions in pain and/or disability in post- compared to pretreatment. In spite of a high level of day-to-day variability in the daily assessments, there were significant reductions in pain and fatigue, and significant increases in positive emotional state and sense of control across the treatment period. In reaching this end, however, some clients had slow and steady improvements, some improved more rapidly, while others got worse before they got better. The natural course of healing-with its inevitable fluctuations in symptoms-is part of a process leading to successful treatment outcomes. Rosen Method Bodywork may be especially helpful in developing and accepting both sensory and emotional body awareness changes that facilitate overall improvement.
Patent Ductus Arteriosus in the Preterm Infant: Diagnostic and Treatment Options.
Prescott, Stephanie; Keim-Malpass, Jessica
2017-02-01
The incidence of hemodynamically significant patent ductus arteriosus (hsPDA) increases with decreasing gestational age and is associated with many common morbidities of extreme prematurity. Controversies remain surrounding the definition of hsPDA, the population of infants requiring treatment, the appropriate timing and method of treatment, and the outcomes associated with PDA and its therapies. This integrative literature review focuses on diagnostic and treatment recommendations derived from the highest levels of evidence. PubMed and CINAHL were searched using key words "neonatal" and "patent ductus arteriosus" to discover the highest levels of evidence surrounding diagnosis, treatment methods, and outcomes. The lack of consensus surrounding the diagnosis and clinical significance of PDA hinders meta-analysis across studies and confounds understanding of appropriate management strategies. Novel biomarkers, pharmaceutical choices, and transcatheter closure methods are expanding diagnostic and treatment options. Infants weighing less than 1000 g are at highest risk. Prophylactic closure is no longer recommended, although early asymptomatic therapy is still preferred by some to avoid prolonged pulmonary overcirculation or decreased renal and gut perfusion. Conservative treatment measures such as fluid restriction and diuretic administration have not consistently proven effective and are in some instances detrimental. Cyclooxygenase inhibitors are effective but have adverse renal and mesenteric effects. Oral ibuprofen is associated with lower instance of necrotizing enterocolitis. Well-defined staging criteria would aid in comparison and meta-analysis. Trials that include a control group that receives no therapy may help separate the outcomes associated with prematurity from those associated with PDA.

Introduction: Chronic periodontitis is the most common periodontal disease which is related to the chronic accumulation of bacterial plaque. Since mechanical methods are not sufficient in the treatment of this disease, administration of local/systemic antibiotic is recommended following mechanical debridement. However, side effects of antibiotics such as microbial resistance and patient allergy led to development of alternative methods. One of these suggested methods is the antimicrobial photodynamic therapy (aPDT). PDT is a local noninvasive treatment modality without the side effects caused by antibiotics. The aim of this study was to review the articles related to the application of PDT with laser in the treatment of chronic periodontitis. Review of literature: In the present review of literature, the authors used key words such as chronic periodontitis, laser and photodynamic therapy, and conducted a literature search via Google Scholar and PubMed for the period of 1990 to 2015. A total of 47 articles in English were found. The articles that were not associated with the topic of research and review articles were deleted and only clinical trials were evaluated. After reviewing 23 articles' abstracts, the full texts of 16 articles were analyzed. Conclusion: Considering the safety, the lack of side effects and general advantages like more patient compliance, the PDT treatment with scaling and root planing (SRP) is recommended as an efficient adjunctive modality for the treatment of localized chronic periodontitis especially during the maintenance phase in non-surgical treatment.

To examine barriers to initiation and continuation of mental health treatment among individuals with common mental disorders. Data were from the World Health Organization (WHO) World Mental Health (WMH) surveys. Representative household samples were interviewed face to face in 24 countries. Reasons to initiate and continue treatment were examined in a subsample (n = 63,678) and analyzed at different levels of clinical severity. Among those with a DSM-IV disorder in the past 12 months, low perceived need was the most common reason for not initiating treatment and more common among moderate and mild than severe cases. Women and younger people with disorders were more likely to recognize a need for treatment. A desire to handle the problem on one's own was the most common barrier among respondents with a disorder who perceived a need for treatment (63.8%). Attitudinal barriers were much more important than structural barriers to both initiating and continuing treatment. However, attitudinal barriers dominated for mild-moderate cases and structural barriers for severe cases. Perceived ineffectiveness of treatment was the most commonly reported reason for treatment drop-out (39.3%), followed by negative experiences with treatment providers (26.9% of respondents with severe disorders). Low perceived need and attitudinal barriers are the major barriers to seeking and staying in treatment among individuals with common mental disorders worldwide. Apart from targeting structural barriers, mainly in countries with poor resources, increasing population mental health literacy is an important endeavor worldwide.

The purpose of this study was to investigate depression treatment preferences and anticipated service use in a sample of adults aged 55 years or older who reside in rural Wyoming. Sixteen participants (mean age = 59) completed 30- to 60-minute, semi-structured interviews. Qualitative methods were used to characterize common themes. Social/provider support and community gatekeepers were perceived by participants as important potential facilitators for seeking depression treatment. In contrast, perceived stigma and the value placed on self-sufficiency emerged as key barriers to seeking treatment for depression in this rural, young-old sample. Participants anticipated presenting for treatment in the primary care sector and preferred a combination of medication and psychotherapy for treatment. Participants were, however, more willing to see mental health professionals if they were first referred by a clergy member or primary care physician. PMID:24409008

The Perceptions of Fair Interpersonal Treatment (PFIT) scale was designed to assess employees' perceptions of the interpersonal treatment in their work environment. Analyses of the factor structure and reliability of this new instrument indicate that the PFIT scale is a reliable instrument composed of 2 factors: supervisor treatment and coworker treatment. It was hypothesized that the PFIT scale would be positively correlated with job satisfaction variables and negatively correlated with work withdrawal, job withdrawal, experiences of sexual harassment, and an organization's tolerance of sexual harassment. Results based on 509 employees in a private-sector organization and 217 female faculty and staff members at a large midwestern university supported these hypotheses. Arguments that common method variance and employees' dispositions are responsible for the significant correlations between the PFIT scale and other job-related variables were eliminated. The implications of these results are discussed.

Treatment of xerostomia is a common clinical challenge in the oral medicine practice. Although some treatments have been used to improve the symptoms of xerostomia, none is completely satisfactory for the patients who suffer of this alteration. In the last years non-pharmacological treatments based on electro-stimulation for the treatment of xerostomia have been developed. This review is aimed at presenting new developments for the treatment of xerostomia, applying neuro-electro-stimulation by miniaturized intra-oral electro-stimulators. These devices increase salivary secretion and improve symptoms of oral dryness. Their effect is obtained by means of stimulation of the lingual nerve, in whose proximity the electrodes of the apparatus are placed. The objective of this mechanism is both to directly stimulate the salivary glands controlled by that nerve and to enhance the salivary reflex. Clinical studies have been carried out that have demonstrated the wetting effect of the method described in this article.

Background Worldwide, oral squamous cell carcinoma (potentially mediated by HER2) is recognized as the most commonly occurring malignant neoplasm of the oral cavity. Anti-HER2 nanobodies conjugated to gold-silica nanoshells and used as photothermal treatment for oral squamous cell carcinoma may provide a novel therapeutic alternative to current treatment for this disease. Methods KB epithelial or HeLaS3 cell cultures (controls) were exposed to these immunonanoshells, and plasmon resonance electron initiation specific to gold was employed to burn the tumor cells. Results Following this treatment, significant cell death occurred in the KB tumor cell cultures while there was no evidence of cellular damage or death in the HeLaS3 cell cultures. Conclusion These findings suggest that photothermal treatment of oral squamous cell carcinoma has considerable advantages. PMID:22131825

Background: Hemifacial spasm is a sudden, involuntary and synchronous spasm of the facial muscles. The most frequent cause of this condition is compression of the facial nerves due to vascular pathologies. The most commonly used method of treatment is Botulinum toxin injection. However, the gold standard treatment is surgical treatment. Case Report: A 64-year-old male patient with hemifacial spasms, which had occurred due to a rare parotid mass that had been surgically treated, is presented in this case. Conclusion: This case report demonstrates that longstanding parotid gland masses may compress the facial nerves and cause demyelination in the nerve and thus may cause spasms in the facial muscles.

Gene Therapy for the Treatment of Diabetic Neuropathy
Mata, Marina; Chattopadhyay, Munmun; Fink, David J
2009-01-01
Neuropathy is a common, untreatable complication of both type 1 and type 2 diabetes. In animal models peptide neurotrophic factors can be used to protect against the development of neuropathy, but the combination of short half-life and off-target effects of these potent pleiotropic peptides has limited translation to human therapy. Gene transfer is a promising strategy that might circumvent these limitations. In this essay we review the basic methods of gene transfer and the preclinical data in rodent models that support the utility of this approach in the treatment of diabetic neuropathy. The path to a clinical applications and potential pitfalls in developing gene therapy for the treatment of diabetic neuropathy are considered. PMID:18990298

By using He-Ne laser treatment, 84.7 - 91.1% of patients with menorrhagia, a common symptom of multiple gynecological diseases, are treated effectively. After laser irradiation, the amount of vaginal bleeding was reduced 47.1% on average. It has been proven that low-energy laser is an effective non-traumatic, painless, and easily acceptable new physical method in patients with menorrhagia. To study the mechanisms of efficiency, the quantitative determination of PGE2, PGF2(alpha ), 6-Keto-PGF1(alpha ), TXB2 in endometrium and blood flow before and after treatment were carried out. The results suggest that the effectiveness may be due to the recovery regulation of local uterine PGS level.

Breast cancer is one of the most commonly diagnosed neoplasms among American women and the second leading cause of death among women all over the world. In order to reduce the mortality rate and cost of treatment, early diagnosis and treatment are essential. Accurate and reliable diagnosis is required in order to ensure the most effective treatment and a second opinion is often advisable. In this paper, we address the problem of breast lesion detection from ultrasound imagery by means of active contours, whose evolution is driven by maximizing the Bhattacharyya distance1 between the probability density functions (PDFs). The proposed method was applied to ultrasound breast imagery, and the lesion boundary was obtained by maximizing the distance-based energy functional such that the maximum (optimal contour) is attained at the boundary of the potential lesion. We compared the results of the proposed method quantitatively using the Dice coefficient (similarity index)2 to well-known GrowCut segmentation method3 and demonstrated that Bhattacharyya approach outperforms GrowCut in most of the cases.

Zamborsky, Radoslav; Kokavec, Milan; Simko, Lukas; Bohac, Martin
2017-01-26
Carpal Tunnel Syndrome (CTS) is the most common form of entrapment neuropathy. Several authors have investigated the anatomical and pathophysiological features of CTS and have identified several parameters that, in combination, play a significant role in its pathophysiology. Advancement in biological research on CTS has enabled the advent of efficient diagnostic techniques such as provocative tests and nerve conduction studies. Sophisticated technologies, such as magnetic resonance imaging (MRI) and ultrasonography (US), have facilitated the diagnosis of CTS. This review article aims at consolidating the relevant medical literature pertaining to the symptoms, pathophysiology, clinical diagnosis and treatment strategies of CTS. It also compares the various methods of diagnosis and discusses their benefits and disadvantages. Finally, it sheds light on the conservative vs. surgical approach to treatment and compares them. While the surgical approach has proved to be more efficient relative to the conservative methods of steroid injections and splinting, many studies have demonstrated both advantages and adverse effects of the surgical methods. Surgical options and complications are discussed in detail. This article comprehensively summarizes all medical aspects of CTS to update medical professionals' knowledge regarding the disease.

The authors aim is to find out the most common dosages, roads of administration and the effect of 15-Methyl PgF2a (Prostin 15 M) during the treatment of postpartal uterine hypotony 1 to 3 amp. Of Prostin 15 M-1 ml. (250 mg Carboprost) were used deeply muscular, intracervical or intramyometrial, by 51 patients with postpartal hypotony. The most common risk factors associated with the development of postpartal haemorrhage are PIH, prolonged labour, the general anaesthesis and higli multiparity. The adequate treatment with Prostin 15 M woned reduse the life threatening complication in the Labour room. The most efficient is the intracervical way of administration, a good effect could be achieved even with 1 amp. Prostin 15 M when it is applied after the conventional methods and manipulations. The lacu of effect grow Prostin 15 M (in 5.88% in this study) shows that there is another pathology responsible for postpartal hemorrhage and life threatening hemorrhage and this usually requires Laparotomy. We offer every Obstetric Clinic to have 3 amp. Prostin 15 M available and these would spare a lot of negative feelings or emotions and it wont supply a better obstetric outcomes.

The molecular weight of lignin is a fundamental property that infl uences the recalcitrance of biomass and the valorization of lignin. The determination of the molecular weight of lignin in native biomass is dependent on the bioresources used and the isolation and purifi cation procedures employed. The three most commonly employed isolation methods are milled wood lignin (MWL), cellulolytic enzyme lignin (CEL), and enzymatic mild acidolysis lignin (EMAL). Common characterization techniques for determining the molecular weight of lignin will be addressed, with an emphasis on gel permeation chromatography (GPC). This review also examines the mechanisms behind several biological, physical, andmore » chemical pre-treatments and their impact on the molecular weight of lignin. The number average molecular weight (Mn), weight average molecular weight (Mw) and polydispersity index (D) all vary in magnitude depending on the biomass source, pre-treatment conditions, and isolation method. Additionally, there is a growing body of literature that supports changes in the molecular weight of lignin in response to genetic modifi cations in the lignin biosynthetic pathways. This review summarizes different procedures for obtaining the molecular weight of lignin that have been used in recent years and highlight future opportunities for applications of lignin.« less

The cardiovascular diseases occupy a leading place in the structure of overall morbidity affecting the population not only of Russia but also of the majority of the developed countries throughout the world; they thus impose the heavy social and economic burden on both the public healthcare services and the modern society in general. At the same time, systemic atherosclerosis is considered to be one of the most common, severe, and life-threatening condition. Despite the presence of a large number of pharmaceutical and surgical methods for the treatment of this pathology, they are not infrequently lacking the desired effectiveness. The use of the shunting operations and endovascular methods failed to radically resolve the problem of managing systemic atherosclerosis and atherosclerosis of the lower limbs. A relatively novel approach which currently begins to find the ever increasing application for the treatment of patients presenting with cardiovascular pathology is based on the enhanced external counter-pulsation method although both the clinical and theoretical prerequisites of its application were developed rather long ago. This non-invasive therapeutic method allows to increase the perfusion pressure in the coronary arteries in diastole and to reduce the resistance to the cardiac ejection in the systole. The objective of this review article was to perform the analysis of the available literature publications on the use of the enhanced external counter-pulsation technique for the treatment of the patients presenting with the diseases of the cardiovascular system and to evaluate the clinical effectiveness of this approach as well as the availability of the treatment for the patients.
An Approach to Addressing Selection Bias in Survival Analysis
Carlin, Caroline S.; Solid, Craig A.
2014-01-01
This work proposes a frailty model that accounts for non-random treatment assignment in survival analysis. Using Monte Carlo simulation, we found that estimated treatment parameters from our proposed endogenous selection survival model (esSurv) closely parallel the consistent two-stage residual inclusion (2SRI) results, while offering computational and interpretive advantages. The esSurv method greatly enhances computational speed relative to 2SRI by eliminating the need for bootstrapped standard errors, and generally results in smaller standard errors than those estimated by 2SRI. In addition, esSurv explicitly estimates the correlation of unobservable factors contributing to both treatment assignment and the outcome of interest, providing an interpretive advantage over the residual parameter estimate in the 2SRI method. Comparisons with commonly used propensity score methods and with a model that does not account for non-random treatment assignment show clear bias in these methods that is not mitigated by increased sample size. We illustrate using actual dialysis patient data comparing mortality of patients with mature arteriovenous grafts for venous access to mortality of patients with grafts placed but not yet ready for use at the initiation of dialysis. We find strong evidence of endogeneity (with estimate of correlation in unobserved factors ρ̂ = 0.55), and estimate a mature-graft hazard ratio of 0.197 in our proposed method, with a similar 0.173 hazard ratio using 2SRI. The 0.630 hazard ratio from a frailty model without a correction for the non-random nature of treatment assignment illustrates the importance of accounting for endogeneity. PMID:24845211

Background HDR brachytherapy is one of the commonest methods of nasopharyngeal cancer treatment. In this method, depending on how advanced one tumor is, 2 to 6 Gy dose as intracavitary brachytherapy is prescribed. Due to high dose rate and tumor location, accuracy evaluation of treatment planning system (TPS) is particularly important. Common methods used in TPS dosimetry are based on computations in a homogeneous phantom. Heterogeneous phantoms, especially patient-specific voxel phantoms can increase dosimetric accuracy. Materials and Methods In this study, using CT images taken from a patient and ctcreate-which is a part of the DOSXYZnrc computational code, patient-specific phantom was made. Dose distribution was plotted by DOSXYZnrc and compared with TPS one. Also, by extracting the voxels absorbed dose in treatment volume, dose-volume histograms (DVH) was plotted and compared with Oncentra™ TPS DVHs. Results The results from calculations were compared with data from Oncentra™ treatment planning system and it was observed that TPS calculation predicts lower dose in areas near the source, and higher dose in areas far from the source relative to MC code. Absorbed dose values in the voxels also showed that TPS reports D90 value is 40% higher than the Monte Carlo method. Conclusion Today, most treatment planning systems use TG-43 protocol. This protocol may results in errors such as neglecting tissue heterogeneity, scattered radiation as well as applicator attenuation. Due to these errors, AAPM emphasized departing from TG-43 protocol and approaching new brachytherapy protocol TG-186 in which patient-specific phantom is used and heterogeneities are affected in dosimetry.

Electroconvulsive therapy for severe neuropsychiatric lupus with psychosis.
Tan, Lynnette Pei Lin; Tan, Lynnette Ee Sing
2013-09-01
Systemic lupus erythematosus (SLE) is an autoimmune disorder that requires long-term management and can have a profound impact on the quality of life of patients. Among patients with SLE, neuropsychiatric manifestations are fairly common, occurring in up to 75% of patients with SLE. Neuropsychiatric symptoms of SLE (NPSLE) presenting with psychosis, however, is less common, with a prevalence of up to 11%. Treatment of psychosis in NPSLE has largely involved antipsychotics and immunosuppressants, with not much in the literature about the use of electroconvulsive therapy (ECT) as a method of treatment. We report 3 cases of patients who presented with psychosis during a lupus relapse, who were treated successfully with ECT after their symptoms did not improve on medical treatment. Although all 3 patients were treated with antipsychotics and immunosuppressants simultaneously with the ECT sessions, the time scale of these 3 case studies suggests that ECT played a role in the resolution of these patients' symptoms. Our 3 cases highlight that ECT can be safely and effectively used in patients with NPSLE with prominent psychotic symptoms.

Tension-type headache (TTH) is the most common type of chronic recurring head pain. It can occur twice as often in women as in men. It is the most common type of headache. Its lifetime prevalence is 30% to 78% in the general population. TTH treatment should be multilevel. It often consists of taking pain medication, muscle relaxants, antidepressants, using biofeedback therapy, acupuncture, and attending behavioral therapy. Several clinical trials also suggest that botulinum toxin (BTX) may be an effective treatment option for such patients. The aim of this study was to evaluate if BTX can be used as a treatment method in TTH in the light of current medical literature. The authors searched the PubMed, EBSCOhost, OVID, Web of Knowledge, Cochrane Library and CINAHL databases to identify relevant publications. The authors finally included 11 papers-prospective and retrospective cohort studies. Among most of the selected studies, there was a significant correlation between using BTX and reduction of TTH pain intensity and severity. By analyzing qualified studies, it can be concluded that botulinum toxin seems to be effective in TTH management.

A new method for deriving effect sizes from single-case designs is proposed. The strategy is applicable to small-sample time-series data with autoregressive errors. The method uses Generalized Least Squares (GLS) to model the autocorrelation of the data and estimate regression parameters to produce an effect size that represents the magnitude of treatment effect from baseline to treatment phases in standard deviation units. In this paper, the method is applied to two published examples using common single case designs (i.e., withdrawal and multiple-baseline). The results from these studies are described, and the method is compared to ten desirable criteria for single-case effect sizes. Based on the results of this application, we conclude with observations about the use of GLS as a support to visual analysis, provide recommendations for future research, and describe implications for practice.

In the parent intervention outcome literatures, discipline practices are generally quantified as absolute frequencies or, less commonly, as relative frequencies. These differences in methodology warrant direct comparison as they have critical implications for study results and conclusions among treatments targeted at reducing parental aggression and harsh discipline. In this study, we directly compared the absolute frequency method and the relative frequency method for quantifying physically aggressive, psychologically aggressive, and nonaggressive discipline practices. Longitudinal data over a 3-year period came from an existing data set of a clinical trial examining the effectiveness of a psychosocial treatment in reducing parental physical and psychological aggression and improving child behavior (N = 139). Discipline practices (aggressive and nonaggressive) were assessed using the Conflict Tactics Scale. The two methods yielded different patterns of results, particularly for nonaggressive discipline strategies. We suggest that each method makes its own unique contribution to a more complete understanding of the association between parental aggression and intervention effects.

Glioma, as the most common and lethal intracranial tumor, is a serious disease that causes many deaths every year. Good comprehension of the mechanism underlying this disease is very helpful to design effective treatments. However, up to now, the knowledge of this disease is still limited. It is an important step to understand the mechanism underlying this disease by uncovering its related genes. In this study, a graphic method was proposed to identify novel glioma related genes based on known glioma related genes. A weighted graph was constructed according to the protein-protein interaction information retrieved from STRING and the well-known shortest path algorithm was employed to discover novel genes. The following analysis suggests that some of them are related to the biological process of glioma, proving that our method was effective in identifying novel glioma related genes. We hope that the proposed method would be applied to study other diseases and provide useful information to medical workers, thereby designing effective treatments of different diseases.

A method combines solid phase acidification with two non-toxic biocides to prevent ammonia volatilization and microbial proliferation. The safe, non-oxidizing biocide combination consists of a quaternary amine and a food preservative. This combination has exhibited excellent stabilization of both acidified and unacidified urine. During pretreatment tests, composite urine collected from donors was challenged with a microorganism known to proliferate in urine, and then was processed using the nonhazardous urine pre-treatment method. The challenge microorganisms included Escherichia coli, a common gram-negative bacteria; Enterococcus faecalis, a ureolytic gram-positive bacteria; Candida albicans, a yeast commonly found in urine; and Aspergillus niger, a problematic mold that resists urine pre-treatment. Urine processed in this manner remained microbially stable for over 57 days. Such effective urine stabilization was achieved using non-toxic, non-oxidizing biocides at higher pH (3.6 to 5.8) than previous methods in use or projected for use aboard the International Space Station (ISS). ISS urine pretreatment methods employ strong oxidants including ozone and hexavalent chromium (Cr(VI)), a carcinogenic material, under very acidic conditions (pH = 1.8 to 2.4). The method described here offers a much more benign chemical environment than previous pretreatment methods, and will lower equivalent system mass (ESM) by reducing containment volume and mass, system complexity, and crew time needed to handle pre-treatment chemicals. The biocides, being non-oxidizing, minimize the potential for chemical reactions with urine constituents to produce volatile, airborne contaminants such as cyanogen chloride. Additionally, the biocides are active under significantly less acidic conditions than those used in the current system, thereby reducing the degree of required acidification. A simple flow-through solid phase acidification (SPA) bed is employed to overcome the natural buffering capacity of urine, and to lower the pH to levels that fix ammoniacal nitrogen in the non-volatile and highly water soluble NH4 + form. Citric acid, a highly soluble, solid tricarboxylic acid essential to cellular metabolism, and typically used as a food preservative, has also been shown to efficiently acidify urine in conjunction with non-oxidizing biocides to provide effective stabilization with respect to both microbial growth and ammonia volatilization.

Although common mental disorder (CMD) is highly prevalent among South Asian immigrant women, they rarely seek mental treatment. This may be owing in part to the lack of conceptual synchrony between medical models of mental disorder and the social models of distress common in South Asian communities. Furthermore, common mental health screening and diagnostic measures may not adequately capture distress in this group. Community-based participatory research (CBPR) is ideally suited to help address measurement issues in CMD as well as to develop culturally appropriate treatment models. To use participatory methods to identify an appropriate, culturally specific mental health syndrome and develop an instrument to measure this syndrome. We formed a partnership between researchers, clinicians, and community members. The partnership selected a culturally specific model of emotional distress/illness, "tension," as a focus for further study. Partners developed a scale to measure Tension and tested the new scale on 162 Bangladeshi immigrant women living in the Bronx. The 24-item "Tension Scale" had high internal consistency (α = 0.83). On bivariate analysis, the scale significantly correlated in the expected direction with depressed as measured by the Patient Health Questionnaire (PHQ-2), age, education, self-rated health, having seen a physician in the past year, and other variables. Using participatory techniques, we created a new measure designed to assess CMD in an isolated immigrant group. The new measure shows excellent psychometric properties and will be helpful in the implementation of a community-based, culturally synchronous intervention for depression. We describe a useful strategy for the rapid development and field testing of culturally appropriate measures of mental distress and disorder.

Our purpose was to demonstrate the efficacy of the 308-nm excimer laser for treatment of psoriasis. This study was a multicenter open trial from 5 dermatology practices (one university-based and 4 private practices). Up to 30 patients per center with stable mild to moderate plaque-type psoriasis constituted the study population. Patients received 308-nm ultraviolet B doses to affected areas. The initial dose was based on multiples of a predetermined minimal erythema dose. Subsequent doses were based on the response to treatment. Treatments were scheduled twice weekly for a total of 10 treatments. The main outcome measure was 75% clearing of the target plaque. Time to clearing was analyzed by Kaplan-Meier methods, accounting for truncated observations. One hundred twenty-four patients were enrolled in the study, and 80 completed the entire protocol. The most common reason for exiting from the study was noncompliance. Of the patients who met the protocol requirements of 10 treatments or clearing, 72% (66/92) achieved at least 75% clearing in an average of 6.2 treatments. Eighty-four percent of patients (95% confidence interval [CI], 79%-87%) reached improvement of 75% or better after 10 or fewer treatments. Fifty percent of patients (95% CI, 35%-61%) reached improvement of 90% or better after 10 or fewer treatments. Common side effects included erythema, blisters, hyperpigmentation, and erosions, but they were well tolerated. Monochromatic 308-nm excimer laser treatment appears to be effective and safe for psoriasis. It requires fewer patient visits than conventional phototherapy, and, unlike those treatments, the laser targets only the affected areas of the skin, sparing the surrounding uninvolved skin.

Generalized anxiety disorder (GAD) is a common disorder in older adults producing functional impairment, and psychotherapy is the preferred treatment option. Meta-analytic methods sought to determine the efficacy of outpatient cognitive behavioral therapy (CBT) with respect to the hallmark feature of GAD-uncontrolled and excessive worry. In order to optimize clinical applicability, variables associated with GAD treatment outcomes were also examined. Systematic search of relevant databases and iterative searches of references from articles retrieved. All studies were required to have been a randomized control trial (RCT), to have used the Penn State Worry Questionnaire (PSWQ) or its abbreviated version (PSWQ-A) as an outcome measure, and to have conducted CBT with outpatient older adults. Fourteen RCTs (N = 985) were suitable and random-effects meta-analyses and univariate meta-regressions were conducted. At the end of treatment, and at 6-month follow-up, significant treatment effects favoring CBT were found in comparison to a waitlist or treatment-as-usual. When CBT was compared with active controls, a small nonsignificant treatment advantage was found for CBT at the end of treatment, with equivalence of outcomes at follow-up. Treatment effect size of CBT for GAD was significantly associated with attrition rates and depression outcomes. CBT is more helpful than having no treatment for GAD in later life. Nevertheless, whether CBT shows long-term durability, or is superior to other commonly available treatments (such as supportive psychotherapy), remains to be tested. The relationship between treatment effects for GAD and depression following CBT warrants further research. Copyright © 2016 American Association for Geriatric Psychiatry. Published by Elsevier Inc.

Urine drug testing is used by health care providers to determine a patient's compliance to their prescribed regimen and to detect non-prescribed medications and illicit drugs. However, the cutoff levels used by clinical labs are often arbitrarily set and may not reflect the urine drug concentrations of compliant patients. Our aim was to test the hypothesis that commonly used cutoffs for many prescribed and illicit drugs were set too high, and methods using these cutoffs may yield a considerable number of false-negative results. The goals of this study were to outline the way to analyze patient results and estimate a more appropriate cutoff, develop and validate a high sensitivity analytical method capable of quantitating drugs and metabolites at lower than the commonly used cutoffs, and determine the number of true positive results that would have been missed when using the common cutoffs. This was a retrospective study of urine specimens submitted for urine drug testing as part of the monitoring of prescription drug compliance described in chronic opioid therapy treatment guidelines. The study was set in a clinical toxicology laboratory, using specimens submitted for routine analysis by health care providers in the normal course of business. Lognormal distributions of test results were generated and fitted with a trendline to estimate the required cutoff level necessary to capture the normal distributions of each drug for the patient population study. A validated laboratory derived liquid chromatography tandem mass spectrometry (LC-MS/MS) analysis capable of achieving the required cutoff levels was developed for each drug and/or metabolite. The study shows that a lognormal distribution of patient urine test results fitted with a trendline is appropriate for estimating the required cutoff levels needed to assess medication adherence. The study showed a wide variation in the false-negative rate, ranging from 1.5% to 94.3% across a range of prescribed and illicit drugs. The patient specimens were largely sourced from patients in either a long-term pain management program or in treatment for substance use disorder in the US. These specimens may not be representative of patients in other types of treatment or in countries with different approaches to these issues. The high-sensitivity method reduces false-negative results which could negatively impact patient care. Clinicians using less sensitive methods for detecting and quantifying drugs and metabolites in urine should exercise caution in assessing patient adherence using and changing the treatment plan based on those results.

To define criteria and to estimate diagnostic significance of endosonography in differential diagnosis of benign and malignant stenoses of common bile duct. We presented the results of survey and treatment of 57 patients with benign and malignant stenoses of common bile duct. The technique of endosonography is described. We have formulated major criteria of differential diagnostics of tumoral and non-tumoral lesion of extrahepatic bile ducts. Comparative analysis of endosonography, ultrasound, computed tomography and magnetic resonance cholangiopancreatography was performed. Sensitivity, specificity and accuracy of endosonography in diagnosis of stenosis cause is 97.7%, 100% and 98.2% respectively. So it exceeds the efficacy of other diagnostic X-ray methods. In modern surgical clinic endosonography should be mandatory performed. It is necessary for final diagnostics of cause of common bile duct stenosis especially in case of its low location.

Non-steroidal anti-inflammatory drugs (NSAIDs) are an effective and common treatment for chronic pain disorders, but long-term use is associated with risk of potentially life-threatening gastrointestinal adverse events (AEs). The proton pump inhibitor esomeprazole has been found to be effective for gastroprotection in NSAID users, but few long-term studies have been conducted in Japan. This was an open-label, multicentre, single-arm, prospective 1-year study of treatment with esomeprazole (20 mg once daily) in Japanese patients (aged ≥20 years) with endoscopic evidence of previous peptic ulcer and receiving daily oral NSAID therapy (at a stable dose) for a chronic condition. Eligibility was not dictated by type of oral NSAID. The primary objective was to determine long-term safety and tolerability of esomeprazole. Efficacy for prevention of peptic ulcers was also determined (Kaplan-Meier method). All statistical analyses were descriptive. A total of 130 patients (73.1% women, mean age 62.1 years, 43.8% Helicobacter pylori-positive) received treatment with esomeprazole in addition to long-term NSAID therapy (most commonly for rheumatoid arthritis [n=42] and osteoarthritis [n=34]). Loxoprofen, meloxicam and diclofenac were the most commonly used NSAIDs; cyclo-oxygenase (COX)-2 selective agents were used by 16.2% of patients (n=21). Long-term compliance with esomeprazole (capsule counts) was >75% for the majority of patients. Although 16.9% of patients (n=22) experienced AEs judged to be possibly related to treatment with esomeprazole, they were mostly mild and transient. The most commonly reported possibly treatment-related AEs were abnormal hepatic function, headache, increased γ-glutamyltransferase levels and muscle spasms (2 patients each). Overall, 95.9% (95% confidence interval: 92.3, 99.4) of patients remained ulcer free at 1 year. Long-term treatment with esomeprazole (20 mg once daily) is well tolerated and efficacious for preventing ulcer recurrence in Japanese NSAID users with a history of peptic ulcer.

Objectives There is no consensus on whether studies with no observed events in the treatment and control arms, the so-called both-armed zero-event studies, should be included in a meta-analysis of randomised controlled trials (RCTs). Current analytic approaches handled them differently depending on the choice of effect measures and authors' discretion. Our objective is to evaluate the impact of including or excluding both-armed zero-event (BA0E) studies in meta-analysis of RCTs with rare outcome events through a simulation study. Method We simulated 2500 data sets for different scenarios varying the parameters of baseline event rate, treatment effect and number of patients in each trial, and between-study variance. We evaluated the performance of commonly used pooling methods in classical meta-analysis—namely, Peto, Mantel-Haenszel with fixed-effects and random-effects models, and inverse variance method with fixed-effects and random-effects models—using bias, root mean square error, length of 95% CI and coverage. Results The overall performance of the approaches of including or excluding BA0E studies in meta-analysis varied according to the magnitude of true treatment effect. Including BA0E studies introduced very little bias, decreased mean square error, narrowed the 95% CI and increased the coverage when no true treatment effect existed. However, when a true treatment effect existed, the estimates from the approach of excluding BA0E studies led to smaller bias than including them. Among all evaluated methods, the Peto method excluding BA0E studies gave the least biased results when a true treatment effect existed. Conclusions We recommend including BA0E studies when treatment effects are unlikely, but excluding them when there is a decisive treatment effect. Providing results of including and excluding BA0E studies to assess the robustness of the pooled estimated effect is a sensible way to communicate the results of a meta-analysis when the treatment effects are unclear.

Compulsive buying is a disorder that has begun to receive attention from researchers in recent years. The results of a handful of studies suggest that compulsive buying occurs in response to negative emotions and results in a decrease in the intensity of the negative emotions. In this investigation, we used interview and self-monitoring methods to evaluate the antecedents and consequences of compulsive buying in a sample of women who met criteria for compulsive buying on the compulsive buying scale (J. Consumer Res. 19 (1992) 459). As a group, the participants reported negative emotions as the most common antecedents to compulsive buying, and euphoria or relief from the negative emotions as the most common consequence of compulsive buying. These findings were consistent across the interview and self-monitoring assessment methods. The implications for assessment and treatment are discussed.
Compulsive Sexual Behavior: A Review of the Literature
Derbyshire, Katherine L.; Grant, Jon E.
2015-01-01
Background and Aims Compulsive sexual behavior (CSB) is a common disorder featuring repetitive, intrusive and distressing sexual thoughts, urges and behaviors that negatively affect many aspects of an individual’s life. This article reviews the clinical characteristics of CSB, cognitive aspects of the behaviors, and treatment options. Methods We reviewed the literature regarding the clinical aspects of CSB and treatment approaches. Results The literature review of the clinical aspects of CSB demonstrates that there is likely a substantial heterogeneity within the disorder. In addition, the treatment literature lacks sufficient evidence-based approaches to develop a clear treatment algorithm. Conclusions Although discussed in the psychological literature for years, CSB continues to defy easy categorization within mental health. Further research needs to be completed to understand where CSB falls within the psychiatric nosology. PMID:26014671

Hypoxic-ischemic encephalopathy (HIE) is a common and potentially devastating condition in the neonate, associated with high mortality and morbidity. Effective treatment options are limited and therefore alternative therapies such as acupuncture are increasingly used. Previous studies have shown that electro acupuncture promoted proliferation of neural progenitor cell and increased expression of neurotrophic factor in HIE. However, effects of electro acupuncture on downstream signaling pathways have been rarely researched. So, in the present study, we aimed to evaluate the neuroprotective effects of electro acupuncture on HIE and to further investigate the role of GDNF family receptor member RET and its key downstream PI3-K/Akt pathway in the process. A rat HIE model was constructed by the left common carotid artery (LCCA) ligation method in combination with hypoxic treatment. Considering that Baihui (GV20), Dazhui (GV14), Quchi (LI11) and Yongquan (KI1) are commonly used in clinics for stroke treatment and are easy to locate, we chose the above four acupoints as the combination for electro acupuncture treatment which was performed once a day for different time periods. Hematoxylin-eosin (HE) staining and transmission electron microscopy results showed that electro acupuncture could ameliorate neurologic damage and alleviate the degenerative changes of ultra structure of cortical neurons in rats subjected to HIE. And the longer acupuncture treatment lasted, the better its therapeutic effect would be. This was accompanied by gradually increased expression of GDNF family receptor RET at the mRNA level and its downstream signaling Akt at the protein level in the ischemic cortex. These findings suggest that electro acupuncture shows neuroprotective effects in HIE, which at least in part is attributed to activation of PI3-K/Akt signaling pathway.
Idiopathic Hypersomnia: Clinical Features and Response to Treatment
Ali, Mohsin; Auger, R. Robert; Slocumb, Nancy L.; Morgenthaler, Timothy I.
2009-01-01
Objective: A recent American Academy of Sleep Medicine publication identified a need for research regarding idiopathic hypersomnia. We describe various clinical and polysomnographic features of patients with idiopathic hypersomnia, with an emphasis on response to pharmacotherapy. Methods: A retrospective review of our database initially identified 997 patients, utilizing “idiopathic hypersomnia,” “hypersomnia NOS,” and “primary hypersomnia” as keywords. The charts of eligible patients were examined in detail, and data were abstracted and analyzed. Response to treatment was graded utilizing an internally developed scale. Results: Eighty-five patients were ultimately identified (65% female). Median (interquartile range) ages of onset and diagnosis were 19.6 (15.5) and 33.7 (15.5), respectively. During a median follow-up duration of 2.4 (4.7) years, 65% of patients demonstrated a “complete response” to pharmacotherapy as assessed by the authors' grading schema. Methylphenidate was most commonly used as a first-line agent prior to December 1998, but subsequently, modafinil became the most common first drug. At the last recorded follow-up visit, 92% of patients were on monotherapy, with greater representation of methylphenidate versus modafinil (51% vs. 32%). Among these patients, methylphenidate produced a higher percentage of “complete” or “partial” responses than modafinil, although statistical significance was not reached (38/40 [ 95%] vs 22/25 [88%], respectively, p = 0.291). Conclusions: The majority of patients with idiopathic hypersomnia respond well to treatment. Methylphenidate is chosen more often than modafinil as final monotherapy in the treatment of idiopathic hypersomnia, despite the fact that it is less commonly used initially. Further prospective comparisons of medications should be explored. Citation: Ali M; Auger RR; Slocumb NL; Morgenthaler TI. Idiopathic hypersomnia: clinical features and response to treatment.

Background Wernicke-Korsakoff Syndrome (WKS) is a neuropsychiatric syndrome caused by thiamine deficiency. Cancer predisposes to thiamine deficiency through various mechanisms. Although many case reports exist on nonalcoholic WKS in cancer, larger qualitative studies are lacking. Method Retrospective study of patients admitted to a cancer hospital and diagnosed with WKS during routine care on a psychiatric consultation service. Only patients with at least 1 additional supporting feature (magnetic resonance imaging findings, low serum thiamine concentrations, or response to treatment) were included. Data pertaining to demographics, risk factors, phenomenology, and outcomes were abstracted from medical records by chart review. Results In all, 18 patients were included. All patients developed WKS during cancer treatment. Hematologic malignancy, gastrointestinal tract tumors, low oral intake, and weight loss were common risk factors. All patients presented with cognitive dysfunction, most commonly impaired alertness, attention, and short-term memory. All were diagnosed by operational criteria proposed by Caine et al., 1997 (where 2 of the following are required: nutritional deficiency, ocular signs, cerebellar signs, and either altered mental status or mild memory impairment). Few exhibited Wernicke’s classic triad. Diagnostic and treatment delay were common. Only 3 patients recovered fully. Conclusion Nonalcoholic WKS can occur during cancer treatment and manifests clinically as delirium. Diagnosis should be made using operational criteria, not Wernicke’s triad. Most patients were not underweight and had normal serum concentration of vitamin B12 and folate. A variety of mechanisms might predispose to thiamine deficiency and WKS in cancer. Given the high frequency of residual morbidity, studies should focus on decreasing diagnostic and treatment delay. PMID:26791514

Health workers recommend bathing, sponging and other physical methods to treat fever in children and to avoid febrile convulsions. We know little about the most effective methods, or how these methods compare with commonly used drugs. To evaluate the benefits and harms of physical cooling methods used for managing fever in children. We searched the Cochrane Infectious Diseases Group specialized trials register (February 2003), the Cochrane Central Register of Controlled Trials (Issue 1, 2003), MEDLINE (1966 to February 2003), EMBASE (1988 to November 2002), CINHAL (1982 to February 2003), LILACS (February 2003), Science Citation Index (1981 to February 2003), and reference lists of articles. We also contacted researchers in the field. Randomized and quasi-randomized trials comparing physical methods with a drug placebo or no treatment in children with fever of presumed infectious origin. Studies where children in both groups were given an antipyretic drug were included. Two reviewers independently assessed trial methodological quality. One reviewer extracted data and the other checked the data for accuracy. Results were expressed as Relative Risk (RR) with 95% confidence intervals (CI) for discrete variables, and weighted mean differences for continuous outcomes. Seven trials, involving 467 participants, met the inclusion criteria. One small trial (n = 30), comparing physical methods with drug placebo, did not demonstrate a difference in the proportion of children without fever by one hour after treatment in a comparison between physical methods alone and drug placebo. In 2 studies, where all children received an anti-pyretic drug, physical methods resulted in a higher proportion of children without fever at one hour (n=125, RR 11.8, CI 3.39 to 40.8). I; in a third study (n=130), which only reported mean change in temperature, no differences wereas detected. Mild adverse events (shivering and goose pimples) were more common in the physical methods group (3 trials, RR 5.09; CI 1.56 to 16.60). A few small studies demonstrate that tepid sponging helps to reduce fever in children.

Angiographically occult vascular malformations (AOVMs) of the brain have been recognized for many years to cause neurologic morbidity and mortality. They generally become symptomatic due to intracranial hemorrhage, focal mass effect, seizures or headaches. The true incidence of AOVMs is unknown, but autopsy studies suggest that they are more common than high-flow angiographically demonstrable arteriovenous malformations (AVMs). We have developed stereotactic heavy-charged-particle Bragg peak radiosurgery for the treatment of inoperable intracranial vascular malformations, using the helium ion beams at the Lawrence Berkeley Laboratory 184-inch Synchrocyclotron and Bevatron. This report describes the protocol for patient selection, radiosurgical treatment planning method, clinicalmore » and neuroradiologic results and complications encountered, and discusses the strengths and limitations of the method. 10 refs., 1 fig.« less
Calcium Phosphate Growth at Electropolished Titanium Surfaces
Ajami, Elnaz; Aguey-Zinsou, Kondo-Francois
2012-01-01
This work investigated the ability of electropolished Ti surface to induce Hydroxyapatite (HA) nucleation and growth in vitro via a biomimetic method in Simulated Body Fluid (SBF). The HA induction ability of Ti surface upon electropolishing was compared to that of Ti substrates modified with common chemical methods including alkali, acidic and hydrogen peroxide treatments. Our results revealed the excellent ability of electropolished Ti surfaces in inducing the formation of bone-like HA at the Ti/SBF interface. The chemical composition, crystallinity and thickness of the HA coating obtained on the electropolished Ti surface was found to be comparable to that achieved on the surface of alkali treated Ti substrate, one of the most effective and popular chemical treatments. The surface characteristics of electropolished Ti contributing to HA growth were discussed thoroughly. PMID:24955535
User-Centered Design for Psychosocial Intervention Development and Implementation
Lyon, Aaron R.; Koerner, Kelly
2018-01-01
The current paper articulates how common difficulties encountered when attempting to implement or scale-up evidence-based treatments are exacerbated by fundamental design problems, which may be addressed by a set of principles and methods drawn from the contemporary field of user-centered design. User-centered design is an approach to product development that grounds the process in information collected about the individuals and settings where products will ultimately be used. To demonstrate the utility of this perspective, we present four design concepts and methods: (a) clear identification of end users and their needs, (b) prototyping/rapid iteration, (c) simplifying existing intervention parameters/procedures, and (d) exploiting natural constraints. We conclude with a brief design-focused research agenda for the developers and implementers of evidence-based treatments. PMID:29456295

In industrial irradiation facilities, the determination of maximum photon or electron energy is important for regulated processes, such as food irradiation, and for assurance of treatment reproducibility. With electron beam irradiators, this has been done by measuring the depth-dose distribution in a homogeneous material. For X-ray irradiators, an analogous method has not yet been recommended. This paper describes a procedure suitable for typical industrial irradiation processes, which is based on common practice in the field of therapeutic X-ray treatment. It utilizes a measurement of the slope of the exponential attenuation curve of X-rays in a thick stack of polyethylene plates. Monte Carlo simulations and experimental tests have been performed to verify the suitability and accuracy of the method between 3 MeV and 8 MeV.

The Ponseti method for correcting clubfoot is a safe, effective, and minimally invasive treatment that has recently been implemented in Latin America. This study evaluates the initial impact and unique barriers to the diffusion of the Ponseti method throughout this region. Structured interviews were conducted with 30 physicians practicing the Ponseti method in three socioeconomically diverse countries: Chile, Peru and Guatemala. Since learning the Ponseti method, these physicians have treated approximately 1,740 clubfoot patients, with an estimated 1,705 (98%) patients treated using the Ponseti method, and 35 (2%) patients treated using surgical techniques. The barriers were classified into the following themes: physician education, health care system of the country, culture and beliefs of patients, physical distance and transport, financial barriers for patients, and parental compliance with the method. The results yielded several common barriers throughout Latin America including lack of physician education, physical distance to the treatment centers, and financial barriers for patients. Information from this study can be used to inform, and to implement and evaluate specific strategies to improve the diffusion of the Ponseti method for treating clubfoot throughout Latin America.
Global antioxidant response of meat.
Carrillo, Celia; Barrio, Ángela; Del Mar Cavia, María; Alonso-Torre, Sara

The global antioxidant response (GAR) method uses an enzymatic digestion to release antioxidants from foods. Owing to the importance of digestion for protein breakdown and subsequent release of bioactive compounds, the aim of the present study was to compare the GAR method for meat with the existing methodologies: the extraction-based method and QUENCHER. Seven fresh meats were analyzed using ABTS and FRAP assays. Our results indicated that the GAR of meat was higher than the total antioxidant capacity (TAC) assessed with the traditional extraction-based method. When evaluated with GAR, the thermal treatment led to an increase in the TAC of the soluble fraction, contrasting with a decreased TAC after cooking measured using the extraction-based method. The effect of thermal treatment on the TAC assessed by the QUENCHER method seemed to be dependent on the assay applied, since results from ABTS differed from FRAP. Our results allow us to hypothesize that the activation of latent bioactive peptides along the gastrointestinal tract should be taken into consideration when evaluating the TAC of meat. Therefore, we conclude that the GAR method may be more appropriate for assessing the TAC of meat than the existing, most commonly used methods. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.
[Current status and future prospect of internal medicine treatment for advanced esophageal cancer].
Wang, F; Fan, Q X
2016-09-23
Esophageal cancer (EC) is one of common malignant tumors, and the incidence and mortality of EC in China rank the first place in the world. Because of the occult onset, the early atypical symptoms, and the lack of effective early diagnostic methods, most of patients are diagnosed at an advanced stage of the disease and lost the chance of surgery. Comprehensive treatment including palliative medical treatment, molecular targeted therapy, immunotherapy and so on is appropriate for these patients. How to choose the chemotherapy regimen and formulate reasonable treatment plan has become a hot spot in clinical research. Molecular targeted drugs have become a new developmental direction in cancer treatment because of their high specificity and antitumor activity, but the effects on esophageal cancer remain controversial. With the development of immune check point blockade treatment, breakthrough has been made in tumor immunotherapy, which has become an important means in cancer comprehensive treatment and shown a good prospect of treatment.

Hassan, Basheir A.; Shreef, Khalid S.
2014-01-01
Background. Infantile hemangiomas (IHs) are the most common benign tumours of infancy. Propranolol has recently been reported to be a highly effective treatment for IHs. This study aimed to evaluate the efficacy and side effects of propranolol for treatment of complicated cases of IHs. Patients and Methods. This prospective clinical study included 30 children with huge or complicated IHs; their ages ranged from 2 months to 1 year. They were treated by oral propranolol. Treatment outcomes were clinically evaluated. Results. Superficial cutaneous hemangiomas began to respond to propranolol therapy within one to two weeks after the onset of treatment. The mean treatment period that was needed for the occurrence of complete resolution was 9.4 months. Treatment with propranolol was well tolerated and had few side effects. No rebound growth of the tumors was noted when propranolol dosing stopped except in one case. Conclusion. Propranolol is a promising treatment for IHs without obvious side effects. However, further studies with longer follow-up periods are needed. PMID:24899888

Hydrothermal treatment (heating in water) is a common method of general food processing and preparation. For red-meat-based foods, boiling is common; however, how the molecular level effects of this treatment correlate to the overall food properties is not yet well-understood. The effects of differing boiling times on lamb meat and the resultant cooking water were here examined through proteomic evaluation. The longer boiling time was found to result in increased protein aggregation involving particularly proteins such as glyceraldehyde-3-phosphate dehydrogenase, as well as truncation in proteins such as in α-actinin-2. Heat-induced protein backbone cleavage was observed adjacent to aspartic acid and asparagine residues. Side-chain modifications of amino acid residues resulting from the heating, including oxidation of phenylalanine and formation of carboxyethyllysine, were characterized in the cooked samples. Actin and myoglobin bands from the cooked meat per se remained visible on sodium dodecyl sulfate-polyacrylamide gel electrophoresis, even after significant cooking time. These proteins were also found to be the major source of observed heat-induced modifications. This study provides new insights into molecular-level modifications occurring in lamb meat proteins during boiling and a protein chemistry basis for better understanding the effect of this common treatment on the nutritional and functional properties of red-meat-based foods.

To estimate the rate and severity of traumatic brain injury (TBI) among people with co-occurring mental health and substance use disorders and to compare demographic, diagnostic, and institutionalization differences between those who screen positive or negative. Outpatient community mental health center in Washington, District of Columbia. A total of 295 people with co-occurring mental health and substance use disorders enrolled in a prospective study of integrated treatment of substance abuse. Cross-sectional baseline assessment. The Ohio State University TBI Identification Method. Standardized measures assessed psychiatric diagnoses, symptom severity, current and lifetime substance use, and history of institutionalization. Eighty percent screened positive for TBI, and 25% reported at least 1 moderate or severe TBI. TBI was associated with current alcohol use and psychiatric symptom severity and with lifetime institutionalization and homelessness. It was more common among participants with posttraumatic stress disorder, borderline personality disorder, and antisocial personality disorder. Men (vs women) and participants with psychotic disorders (vs those with mood disorders) had an earlier age of first TBI with loss of consciousness. TBI is common among people with co-occurring mental health and substance use disorders. Repeated and serious TBIs are common in this population. Failure to detect TBI in people with co-occurring disorders who are seeking integrated treatment could lead to misdiagnosis and inappropriately targeted treatment and rehabilitation.

To estimate the costs of commonly used treatments for cutaneous warts, as well as their health benefits and risk. To create an economic decision model to evaluate the cost-effectiveness of these treatments, and, as a result, assess whether a randomised controlled trial (RCT) would be feasible and cost-effective. Focus groups, structured interviews and observation of practice. Postal survey sent to 723 patients. A recently updated Cochrane systematic review and published cost and prescribing data. Primary and secondary data collection methods were used to inform the development of an economic decision model. Data from the postal survey provided estimates of the effectiveness of wart treatments in a primary care setting. These estimates were compared with outcomes reported in the Cochrane review of wart treatment, which were largely obtained from RCTs conducted in secondary care. A decision model was developed including a variety of over-the-counter (OTC) and GP-prescribed treatments. The model simulated 10,000 patients and adopted a societal perspective. OTC treatments were used by a substantial number of patients (57%) before attending the GP surgery. By far the most commonly used OTC preparation was salicylic acid (SA). The results of the economic model suggested that of the treatments prescribed by a GP, the most cost-effective treatment was SA, with an incremental cost-effectiveness ratio (ICER) of 2.20 pound/% cured. The ICERs for cryotherapy varied widely (from 1.95 to 7.06 pound/% cured) depending on the frequency of applications and the mode of delivery. The most cost-effective mode of delivery was through nurse-led cryotherapy clinics (ICER = 1.95 pound/% cured) and this could be a cost-effective alternative to GP-prescribed SA. Overall, the OTC therapies were the most cost-effective treatment options. ICERs ranged from 0.22 pound/% cured for OTC duct tape and 0.76 pound/% cured for OTC cryotherapy to 1.12 pound/% cured for OTC SA. However, evidence in support of OTC duct tape and OTC cryotherapy is very limited. Side-effects were commonly reported for both SA and cryotherapy, particularly a burning sensation, pain and blistering. Cryotherapy delivered by a doctor is an expensive option for the treatment of warts in primary care. Alternative options such as GP-prescribed SA and nurse-led cryotherapy clinics provide more cost-effective alternatives, but are still expensive compared with self-treatment. Given the minor nature of most cutaneous warts, coupled with the fact that the majority spontaneously resolve in time, it may be concluded that a shift towards self-treatment is warranted. Although both duct tape and OTC cryotherapy appear promising new self-treatment options from both a cost and an effectiveness perspective, more research is required to confirm the efficacy of these two methods of wart treatment. If these treatments are shown to be as cost-effective as or more cost-effective than conventional treatments, then a shift in service delivery away from primary care towards more OTC treatment is likely. A public awareness campaign would be useful to educate patients about the self-limiting nature of warts and the possible alternative OTC treatment options available. Two future RCTs are recommended for consideration: a trial of SA compared with nurse-led cryotherapy in primary care, and a trial of home treatments. Greater understanding of the efficacy of these home treatments will give doctors a wider choice of treatment options, and may help to reduce the overall demand for cryotherapy in primary care.

The dissolution of the USSR resulted in independence for constituent republics but left them battling an unstable economic environment and healthcare. Increases in injection drug use, prostitution, and migration were all widespread responses to this transition and have contributed to the emergence of an HIV epidemic in the countries of former Soviet Union. Researchers have begun to identify the risks of HIV infection as well as the barriers to HIV testing and treatment in the former Soviet Union. Significant methodological challenges have arisen and need to be addressed. The objective of this review is to determine common threads in HIV research in the former Soviet Union and provide useful recommendations for future research studies. In this systematic review of the literature, Pubmed was searched for English-language studies using the key search terms "HIV", "AIDS", "human immunodeficiency virus", "acquired immune deficiency syndrome", "Central Asia", "Kazakhstan", "Kyrgyzstan", "Uzbekistan", "Tajikistan", "Turkmenistan", "Russia", "Ukraine", "Armenia", "Azerbaijan", and "Georgia". Studies were evaluated against eligibility criteria for inclusion. Thirty-nine studies were identified across the two main topic areas of HIV risk and barriers to testing and treatment, themes subsequently referred to as "risk" and "barriers". Study design was predominantly cross-sectional. The most frequently used sampling methods were peer-to-peer and non-probabilistic sampling. The most frequently reported risks were condom misuse, risky intercourse, and unsafe practices among injection drug users. Common barriers to testing included that testing was inconvenient, and that results would not remain confidential. Frequent barriers to treatment were based on a distrust in the treatment system. The findings of this review reveal methodological limitations that span the existing studies. Small sample size, cross-sectional design, and non-probabilistic sampling methods were frequently reported limitations. Future work is needed to examine barriers to testing and treatment as well as longitudinal studies on HIV risk over time in most-at-risk populations.

Objectives The objective was to determine if decreased platelet function could be detected after treatment with aspirin and/or clopidogrel in healthy cats using three point-of-care platelet function tests that evaluate platelet function by different methods: Multiplate (by impedance), Platelet Function Analyzer 100 (by mechanical aperture closure) and Plateletworks (by platelet counting). Methods Thirty-six healthy cats were randomly assigned to receive one of three oral treatments over an 8 day period: (1) aspirin 5 mg q72h; (2) aspirin 20.25 mg q72h; or (3) clopidogrel 18.75 mg q24h. Cats treated with 5 and 20.25 mg aspirin also received clopidogrel on days 4-8. Platelet aggregation in response to adenosine diphosphate and collagen ± arachidonic acid was assessed on days 1 (baseline), 4 and 8. Aspirin and clopidogrel metabolites were measured by high-performance liquid chromatography. Platelet function in response to treatment was analyzed by ANCOVA, linear regression and Spearman correlation. Results The only solitary aspirin effect was detected using Plateletworks with collagen in cats treated with 20.25 mg. The only effect detected by Multiplate was using arachidonic acid in cats treated with both aspirin 20.25 mg and clopidogrel. All clopidogrel treatment effects were detected by Platelet Function Analyzer 100, Plateletworks (adenosine diphosphate) and Plateletworks (collagen). Drug metabolites were present in all cats, but concentrations were minimally correlated to platelet function test results. Conclusions and relevance Platelet Function Analyzer 100 and Plateletworks using adenosine diphosphate ± collagen agonists may be used to detect decreased platelet function in response to clopidogrel treatment. Either aspirin is not as effective an antiplatelet drug as clopidogrel, or the tests used were not optimal to measure aspirin effect. Cats with heart disease are commonly prescribed antiplatelet drugs to decrease the risk of aortic thromboembolism. Platelet Function Analyzer 100 and Plateletworks may be useful for confirming clopidogrel treatment in these cats.

Hepatocellular carcinoma (HCC), with its high incidence and mortality rate, is one of the most common malignant tumors. Despite recent development of a diagnostic and treatment method, the prognosis of HCC remains poor. Therefore, to provide optimal treatment for each patient with HCC, more precise and effective biomarkers are urgently needed which could facilitate a more detailed individualized decision-making during HCC treatment, including the following; risk assessment, early cancer detection, prediction of treatment or prognostic outcome. In the blood of cancer patients, accumulating evidence about circulating tumor cells and cell-free nucleic acids has suggested their potent clinical utilities as novel biomarker. This concept, so-called “liquid biopsy” is widely known as an alternative approach to cancer tissue biopsy. This method might facilitate a more sensitive diagnosis and better decision-making by obtaining genetic and epigenetic aberrations that are closely associated with cancer initiation and progression. In this article, we review recent developments based on the available literature on both circulating tumor cells and cell-free nucleic acids in cancer patients, especially focusing on Hepatocellular carcinoma.

Basal cell carcinoma (BCC) is the most common cancer in the US population affecting approximately 2.8 million people per year. Basal cell carcinomas are usually slow-growing and rarely metastasize, but they do cause localized tissue destruction, compromised function, and cosmetic disfigurement. To provide clinicians with guidelines for the management of BCC based on evidence from a comprehensive literature review, and consensus among the authors. An extensive review of the medical literature was conducted to evaluate the optimal treatment methods for cutaneous BCC, taking into consideration cure rates, recurrence rates, aesthetic and functional outcomes, and cost-effectiveness of the procedures. Surgical approaches provide the best outcomes for BCCs. Mohs micrographic surgery provides the highest cure rates while maximizing tissue preservation, maintenance of function, and cosmesis. Mohs micrographic surgery is an efficient and cost-effective procedure and remains the treatment of choice for high-risk BCCs and for those in cosmetically sensitive locations. Nonsurgical modalities may be used for low-risk BCCs when surgery is contraindicated or impractical, but the cure rates are lower.

Online knowledge resources such as Medline can address most clinicians’ patient care information needs. Yet, significant barriers, notably lack of time, limit the use of these sources at the point of care. The most common information needs raised by clinicians are treatment-related. Comparative effectiveness studies allow clinicians to consider multiple treatment alternatives for a particular problem. Still, solutions are needed to enable efficient and effective consumption of comparative effectiveness research at the point of care. Objective Design and assess an algorithm for automatically identifying comparative effectiveness studies and extracting the interventions investigated in these studies. Methods The algorithm combines semantic natural language processing, Medline citation metadata, and machine learning techniques. We assessed the algorithm in a case study of treatment alternatives for depression. Results Both precision and recall for identifying comparative studies was 0.83. A total of 86% of the interventions extracted perfectly or partially matched the gold standard. Conclusion Overall, the algorithm achieved reasonable performance. The method provides building blocks for the automatic summarization of comparative effectiveness research to inform point of care decision-making. PMID:23920677

2012-01-01
Background and Objectives: Spinal cord injury is a common neurological problem secondary to car accidents, war injuries and other causes, it may lead to varying degrees of neurological disablement, and apart from physiotherapy there is no available treatment to regain neurological function loss. Our aim is to find a new method using autologous hematopoietic stem cells to gain some of the neurologic functions lost after spinal cord injury. Methods and Results: 277 patients suffering from spinal cord injury were submitted to an intrathecally treatment with peripheral stem cells. The cells were harvested from the peripheral blood after a treatment with G-CSF and then concentrated to 4∼ 6 ml. 43% of the patients improved; ASIA score shifted from A to B in 88 and from A to C in 32. The best results were achieved in patients treated within one year from the injury. Conclusions: Since mesenchymal cells increase in the peripheral blood after G-CSF stimulation, a peripheral blood harvest seems easier and cheaper than mesenchymal cell cultivation prior to injection. It seems reasonable treatment for spinal cord injury. PMID:24298358
New perspectives in the diagnostic of gingival recession.
Dominiak, Marzena; Gedrange, Tomasz
2014-01-01
Gingival recession (GR) is a common clinical situation observed in patient populations regardless of their age and ethnicity. It has been estimated that over 60% of the human population has gingival recession. It is the final effect of the interaction of multiple etiological factors. Identification and definition of the range of influence is often not possible, with the result that new methods for testing and elimination of potential etiological factors are still being sought. The aim of this study is to present the etiopathogenesis of gingival recessions with regard to the analysis of morphological and functional factors. For the assessment of the bone factors, we will describe the new cephalometric method for measuring sagital width of the bone in the central incisors area, places when GR are most commonly observed. Also, a review will be presented of modern methods of treatment; in particular classes recessions; usage substitute of autogenous tissue will be emphasized--collagen matrix, and primary culture fibroblasts on collagen net.
[Endoscopic sphincterotomy in choledocholithiasis and an intact gallbladder].

Endoscopic sphincterotomy (ES) with extraction of calculi is a basic method of treating choledocholithiasis in post-cholecystectomy patients (8, 9). Endoscopic treatment contributes to a considerable reduction of the indications for reoperation. The existing views concerning ES done in patients with preserved gallbladder, especially in the era of laparoscopic surgery, are still conflicting (3, 6). There are several options: cholecystectomy with removal of calculi in the common bile duct by ES in a subsequent stage, or vice versa-primary ES with ensuring cholecystectomy. The undertaking of independent surgical or endoscopic treatment is likewise practicable (2, 6).

Leptospirosis outbreaks have been associated with many common water events including water consumption, water sports, environmental disasters, and occupational exposure. The ability of leptospires to survive in moist environments makes them a high-risk agent for infection following contact with any contaminated water source. Water treatment processes reduce the likelihood of leptospirosis or other microbial agents causing infection provided that they do not malfunction and the distribution networks are maintained. Notably, there are many differences in water treatment systems around the world, particularly between developing and developed countries. Detection of leptospirosis in water samples is uncommonly performed by molecular methods. PMID:25348115

Abstract Many clinical and biomedical studies evaluate treatment effects based on multiple biomarkers that commonly consist of pre- and post-treatment measurements. Some biomarkers can show significant positive treatment effects, while other biomarkers can reflect no effects or even negative effects of the treatments, giving rise to a necessity to develop methodologies that may correctly and efficiently evaluate the treatment effects based on multiple biomarkers as a whole. In the setting of pre- and post-treatment measurements of multiple biomarkers, we propose to apply a receiver operating characteristic (ROC) curve methodology based on the best combination of biomarkers maximizing the area under the receiver operating characteristic curve (AUC)-type criterion among all possible linear combinations. In the particular case with independent pre- and post-treatment measurements, we show that the proposed method represents the well-known Su and Liu's (1993) result. Further, proceeding from derived best combinations of biomarkers' measurements, we propose an efficient technique via likelihood ratio tests to compare treatment effects. We show an extensive Monte Carlo study that confirms the superiority of the proposed test in comparison with treatment effects based on multiple biomarkers in a paired data setting. For practical applications, the proposed method is illustrated with a randomized trial of chlorhexidine gluconate on oral bacterial pathogens in mechanically ventilated patients as well as a treatment study for children with attention deficit-hyperactivity disorder and severe mood dysregulation.
