The paper analyses methadone treatment in Copenhagen – as it is described by methadone users and staff at different outpatient centres. The starting point is a theoretical model distinguishing between two different approaches to methadone treatment: ‘palliative’ and ‘curative’. Included...... in the model are three dimensions (1) treatment goals at the methadone centres (abstinence vs. stabilisation) (2) treatment focus (focus on addiction vs. focus on the consequences of addiction) and (3) conceptualisation of methadone (methadone as similar to or different from heroin). The paper shows...... that there is a discrepancy between the attitudes of the staff and those of the users. While the staff favour an almost clear-cut palliative approach to methadone treatment, defining curative goals as both unrealistic and as belonging to the past, the users prefer an approach that does not exclude the goal of abstinence...

Full Text Available Among the mastication system disorders bruxism is a parafunctional behavior that comes from psychophysiological origin. Epidemiologic studies have reported great variability of bruxism prevalence. The factors that could cause bruxism is highly controversial. There are different opinions on this issue. The etiologic factors of bruxism include stress, malnutrition, allergic and endocrinologic diseases, central nervous system disorders, genetic factors, medicines, malocclusion, and wrong dental treatment. The aim of treatment of bruxism is to prevent damage that may occur on teeth and in the temporomandibular joint and to eliminate pain. Dental treatment, physical therapy, pharmacological treatment and behavioral and cognitive therapy can be considered for this purpose of treatment. This review summarizes the etiologic factors, epidemiology, diagnosis, and current treatment approaches of patient with bruxism. [Archives Medical Review Journal 2016; 25(2.000: 241-258

Gout is the most common form of inflammatory arthritis in the United States. Nevertheless, gout remains misunderstood, misdiagnosed, underdiagnosed, and undertreated. Several new recommendation and guideline documents regarding the management of gout have been published in the past few years. New diagnostic modalities, such as ultrasound and dual-energy computed tomography, are now available. Newer treatment options exist, and older agents and their interactions are now better understood. This review addresses these recent diagnostic and therapeutic developments and describes our management protocol with the aim of providing the clinician with a pragmatic approach to gout management.

Sarcopenia is characterized by progressive and generalized loss of skeletal muscle mass and strength with a risk of adverse outcomes such as physical disability, poor quality of life, and death. Primary sarcopenia is considered to be age-related when no other cause is evident, other than ageing itself. Secondary sarcopenia should be considered when one or more other causes are evident, such as activity-, disease-, or nutrition-related sarcopenia. In this narrative review that focused on human studies, we summarize the pharmaceutical therapies (testosterone, dehydroepiandrosterone, estrogen, growth hormone, ghrelin, vitamin D, angiotensin converting enzyme inhibitor, and eicosapentaenoic acid) and nonpharmaceutical therapies (resistance training, protein and amino acid supplementation, and non-smoking) for counteracting primary sarcopenia. Testosterone and growth hormone improve muscle mass and muscle strength, but have several side effects. Although there are some intriguing pharmaceutical therapies to combat sarcopenia, resistance training combined with supplements containing amino acids are the most effective for preventing and treating age-related muscle wasting and weakness. The etiology of sarcopenia in the elderly is multi-factorial. Patients with disuse syndrome and deconditioning often complicate the diagnosis, of not only activity-related sarcopenia, but also age-, disease-, and nutrition-related sarcopenia. In these cases a comprehensive approach to sarcopenia treatment should include pharmaceutical therapies for age-related sarcopenia and comorbid chronic diseases, resistance training, early ambulation, nutrition management, protein and amino acid supplementation, and non-smoking. The effect of pharmaceutical therapies for sarcopenia can be enhanced by this comprehensive approach. Future research on pharmaceutical therapies for counteracting sarcopenia should consider non-pharmaceutical therapies and also the causes of sarcopenia.

Full Text Available Angioedema (AE is defined as sudden, localized and transient swelling of the skin and/or mucous membranes. This swelling condition is a result of interstitial edema from vasoactive mediators increasing the permeability of postcapillary venules of the subcutaneous and submucosal tissues. When localized to the skin, it presents as asymmetric, nonpitting, nondependent, and occasionally painful edema. However, mucosal attacks, such as laryngeal edema and bowel involvement can produce severe discomfort and life-threatening symptoms. There are several forms including those involving dysfunction or depletion of the C1-inhibitor gene (classical hereditary AE types and acquired AE, allergic AE, drug-induced AE (nonsteroidal anti-inflammatory drug-induced AE, angiotensin converting enzyme inhibitor-induced AE, idiopathic and a recently described form, HAE type 3. These various forms of AE have overlapping symptoms, but some unique clinical and historical features as well as presence of accompanying urticaria can aid in the differential diagnosis. The key to successful management is to rule out conditions that masquerade as AE, detection and avoidance of triggers, early recognition of attacks, and aggressive airway management when warranted. In this article, common and rare forms as well as clinical symptoms, differential diagnosis, and treatment approaches for AE are reviewed.

The paucity of evidence and detail in the literature regarding speech treatment for children with dysarthria due to cerebral palsy (CP) renders it difficult for researchers to replicate studies and make further inroads into this area in need of exploration. Furthermore, for speech-language pathologists (SLPs) wishing to follow treatments that the literature indicates have promise, little guidance is available on the details of the treatments that yielded the positive results. The present article details the implementation of two treatment approaches in speech treatment research for children with dysarthria: Speech Systems Intelligibility Treatment (SSIT) and the Lee Silverman Voice Treatment LOUD (LSVT LOUD). Specific strategies, primarily for treatment, but also for outcome measurement and acoustic analysis of dysarthric speech, are described. These techniques are provided for researchers and clinicians to consider implementing in order to advance speech treatment for this population. New data from research using these approaches are presented, including findings of acoustic vowel space changes following both speech treatments.
Full Text Available Cutaneous leishmaniasis (CL is a widespread tropical infection caused by numerous different species of Leishmania protozoa. In our country, CL is due frequently to L. major and L. tropica. Its clinical presentation is extremely diverse. Treatment of CL aims to prevent mucosal invasion, to accelerate the healing of skin lesions, and avoid disfiguring scar. Local and physical treatment modalities including topical paromomycin, cryotherapy, localized controlled heat, carbon dioxide laser therapy, or pentavalant antimonals can be effective against. Intralesional antimonals are still the drug of choice may patients. WHO recommends an injection of drug under edges of the lesions and the entire lesion until the surface has blanched. Parenteral antimonials are useful for large, persistent or recurrent lesions. Combinations with other drugs such as allopurinol, pentoxifylline must be used for antimony unresponsive lesions.

The therapeutic management of pemphigus vulgaris (PV) is centered around immunosuppression, which can be generalized, as in the use of corticosteroids or steroid sparing agents, or specific, as in therapeutic blockage of autoantibody production, certain cytokines, or signaling pathways. Currently, the backbone of treatment for PV, particularly, first line therapy, remains systemic corticosteroids. Although very effective, the significant side effects of long-term corticosteroid usage are well documented. Adjunctive therapies aim to eliminate, or at least decrease, the necessary dose of corticosteroids. Specifically, azathioprine, cyclophosphamide, methotrexate, cyclosporine, mycophenolate mofetil and dapsone are now widely used in PV. Intravenous immunoglobulin (IVIG), plasmapheresis, immunoadsorption, and most recently, rituximab, are other members of the therapeutic armamentarium. However, despite the widening range of treatment options in PV, well-controlled clinical trials and consensus guidelines are lacking.
Complementary and alternative medicine (CAM) is a diverse group of health care practices and products that fall outside the realm of traditional Western medical theory and practice and that are used to complement or replace conventional medical therapies. The use of CAM has increased over the past two decades, and surveys have shown that up to 44% of patients with epilepsy are using some form of CAM treatment. This article reviews the CAM modalities of meditation, yoga, relaxation techniques, biofeedback, nutritional and herbal supplements, dietary measures, chiropractic care, acupuncture, Reiki, and homeopathy and what is known about their potential efficacy in patients with epilepsy.

Full Text Available Microscopic colitis – including collagenous colitis and lymphocytic colitis – causes chronic watery diarrhea, usually in middle-aged or elderly patients. There is an association with celiac disease and certain medications. Medical treatment includes various antidiarrheal agents, mesalamine, corticosteroids and immunosuppressant drugs. Rarely, patients require surgery for refractory disease. An evidence-based and practical approach to treatment should optimize the treatment response while minimizing potential adverse events.

Treacher Collins syndrome (TCS) is a common genetic disorder with high penetrance and phenotypic variability. First and second branchial arches are affected in TCS, resulting in craniofacial and intraoral anomalies such as: severe convex facial profile; mid-face hypoplasia; microtia; eyelid colobomas; mandibular retrognathism; cleft palate; dental hypoplasia; heterotopic teeth; maxillary transverse hypoplasia; anterior open bite; and Angle Class II molar relationship. A high incidence of caries is also a typical finding in TCS patients. Nonetheless, even simple dental restorative procedures can be challenging in this patient population due to other associated medical conditions, such as: congenital heart defects; decreased oropharyngeal airways; hearing loss; and anxiety toward treatment. These patients often require a multidisciplinary treatment approach, including: audiology; speech and language pathology; otorhinolaryngology; general dentistry; orthodontics; oral and maxillofacial surgery; and plastic and reconstructive surgeries to improve facial appearance. This paper's purpose was to present a current understanding of Treacher Collins syndrome etiology, phenotype, and current treatment approaches.

Anhedonia, or loss of interest or pleasure in usual activities, is characteristic of depression, some types of anxiety, as well as substance abuse and schizophrenia. Anhedonia is a predictor of poor long-term outcomes, including suicide, and poor treatment response. Because extant psychological and pharmacological treatments are relatively ineffective for anhedonia, there is an unmet therapeutic need for this high-risk symptom. Current psychological and drug treatments for anxiety and depression focus largely on reducing excesses in negative affect rather than improving deficits in positive affect. Recent advances in affective neuroscience posit that anhedonia is associated with deficits in the appetitive reward system, specifically the anticipation, consumption, and learning of reward. In this paper, we review the evidence for positive affect as a symptom cluster, and its neural underpinnings, and introduce a novel psychological treatment for anxiety and depression that targets appetitive responding. First, we review anhedonia in relation to positive and negative valence systems and current treatment approaches. Second, we discuss the evidence linking anhedonia to biological, experiential, and behavioral deficits in the reward subsystems. Third, we describe the therapeutic approach for Positive Affect Treatment (PAT), an intervention designed to specifically target deficits in reward sensitivity. © 2016 Wiley Periodicals, Inc.

Full Text Available Problem statement: The achievement of a good ecological status of water receivers after discharge of waste or partially treated water from dairy industry requires harmonic interaction between water treatment technology and self-purification processes. Approach: The present research included two modules. First: an anaerobic treatment process for dairy wastewater in broadly spread sequencing batch bioreactor with fixed biomass was studied. As a source of active biological system specially treated and acclimated activated sludge from Sofia Wastewater Treatment Plant was used. The acclimation and immobilization of initially inoculated biomass, the addition of microbiological preparations and its modification for increase of the biodegradation activity to target pollutants were studied as opportunities for the stimulation of water treatment process in bioreactors and water receiver. Second: self-purification processes in а water receiver for partially treated dairy wastewater were investigated. The functional role and restructuring of the microbial communities in the water, sediment water and sediments were studied. Results: The results showed that the most important approaches for achieving high effectiveness of wastewater treatment process were both the acclimation and immobilization of biomass. In that aspect the data for the water receiver confirmed this conclusion. These two processes increased biodegradation effectiveness of the target pollutant (protein with 67%. Conclusion: The effect of the added preparations was smaller (protein biodegradation was increased to 9% for the different biological systems. It was thoroughly related to low improvement of the rate of metabolism and functioning of the biological system mainly on an enzyme level.

There have been significant advances in the immunotherapy of melanoma over the last decade. The tumor microenvironment is now known to promote an immune-suppressive milieu that can block effective immune-mediated tumor rejection. Several novel strategies designed to overcome local immunosuppression hold promise for treatment of melanoma and other cancers. These approaches include oncolytic viruses, plasmid DNA delivery, Toll-like receptor agonists, inflammatory dyes, cytokines, checkpoint inhibitors, immunomodulatory agents, and host and pathogenic cell-based vectors. In addition, there are several novel methods for local drug delivery, including direct injection, image-guided, electroporation, and nanodelivery techniques under study. The approval of talimogene laherparepvec (Imlygic), an attenuated, recombinant oncolytic herpesvirus, for melanoma treatment is the first intratumoral agent to receive regulatory approval for the treatment of patients with melanoma. This review will focus on the rationale for intratumoral treatment in melanoma, describe the clinical and safety data for some of the agents in clinical development, and provide a perspective for future clinical investigation with intratumoral approaches. Melanoma has been a paradigm tumor for progress in targeted therapy and immunotherapy and will likely also be the tumor to establish the therapeutic role of intratumoral treatment for cancer.

The past decade has brought important advances in the understanding of rheumatoid arthritis and its management and treatment. New classification criteria for rheumatoid arthritis, better definitions of treatment outcome and remission, and the introduction of biologic response-modifying drugs designed to inhibit the inflammatory process have greatly altered the approach to managing this disease. More aggressive management of rheumatoid arthritis early after diagnosis and throughout the course of the disease has resulted in improvement in patient functioning and quality of life, reduction in comorbid conditions, and enhanced survival.

Conclusion: Although the regenerative treatment approaches have good clinical outcomes in the majority of case reports, the outcomes are unpredictable. Since the current clinical protocols for regenerative endodontics do not fully fulfill the triad of tissue engineering ((growth factors, scaffold and stem cells, further translational studies are required to achieve more pulp- and dentin-like tissue in the root canal system to achieve pulp regeneration.

A programme to improve 'continuity of care' was initiated at Bourn Hall Clinic in direct response to patient demand to see the same doctors and nurses throughout assisted conception treatment cycles. A working party comprising individuals from all disciplines involved in assisted conception care was set up to review practices and aims and to establish an action plan. As a result, in 1996, a team approach to in vitro fertilization (IVF) and frozen embryo transfer (FET) treatment cycles was introduced at the clinic. The nursing staff were divided into two teams, each with a leader, an appropriate skill mix of full- and part-time nurses, and one full-time and one relief doctor. Treatment cycles were scheduled using pituitary downregulation with gonadotrophin-releasing hormone (GnRH) agonist when appropriate, and a programme was devised in which groups of 40--45 couples started treatment during the same 5 day period. Each couple was assigned to one of the teams and starting dates for each group were separated by 2 week intervals. The objectives of the working party were successfully achieved. The team approach to treating a finite number of couples provides a better opportunity for individualized care. Couples appreciate the advantages of continuity of care and the improved rapport with team staff. Forward planning of treatment cycles provides greater flexibility for incorporating clinic visits into patients' normal routines. Staff have benefited from increased job satisfaction due to greater involvement with couples from initial contact to the completion of treatment. The new working practice provides opportunities for training and research. Staff costs have been rationalized with benefits both to couples and to the business unit.

Hypertension is the most common modifiable risk factor for cardiovascular disease and death, and lowering blood pressure with antihypertensive drugs reduces target organ damage and prevents cardiovascular disease outcomes. Despite a plethora of available treatment options, a substantial portion of the hypertensive population has uncontrolled blood pressure. The unmet need of controlling blood pressure in this population may be addressed, in part, by developing new drugs and devices/procedures to treat hypertension and its comorbidities. In this Compendium Review, we discuss new drugs and interventional treatments that are undergoing preclinical or clinical testing for hypertension treatment. New drug classes, eg, inhibitors of vasopeptidases, aldosterone synthase and soluble epoxide hydrolase, agonists of natriuretic peptide A and vasoactive intestinal peptide receptor 2, and a novel mineralocorticoid receptor antagonist are in phase II/III of development, while inhibitors of aminopeptidase A, dopamine β-hydroxylase, and the intestinal Na(+)/H(+) exchanger 3, agonists of components of the angiotensin-converting enzyme 2/angiotensin(1-7)/Mas receptor axis and vaccines directed toward angiotensin II and its type 1 receptor are in phase I or preclinical development. The two main interventional approaches, transcatheter renal denervation and baroreflex activation therapy, are used in clinical practice for severe treatment resistant hypertension in some countries. Renal denervation is also being evaluated for treatment of various comorbidities, eg, chronic heart failure, cardiac arrhythmias and chronic renal failure. Novel interventional approaches in early development include carotid body ablation and arteriovenous fistula placement. Importantly, none of these novel drug or device treatments has been shown to prevent cardiovascular disease outcomes or death in hypertensive patients.
Osteoporosis has been recognized as a major public health problem for less than two decades. The increasing incidence of fragility fractures, such as vertebral, hip, and wrist fractures, first became apparent from epidemiological studies in the early and mid-1980s, when effective treatment was virtually unavailable. Pharmacological therapies that effectively reduce the number of fractures by improving bone mass are now available widely in countries around the world. Most current agents inhibit bone loss by reducing bone resorption, but emerging therapies may increase bone mass by directly promoting bone formation--as is the case with parathyroid hormone. Current treatment alternatives include bisphosphonates, calcitonin, and selective estrogen receptor modulators, but sufficient calcium and vitamin D are a prerequisite. The availability of evidence-based data that show reductions in the incidence of fractures of 30-50% during treatment has been a major step forward in the pharmacological prevention of fractures. With all agents, fracture reduction is most pronounced for vertebral fracture in high-risk individuals; alendronate and risedronate also may protect against hip fracture in the elderly. New approaches to pharmacological treatment will include further development of existing drugs, especially with regard to tolerance and frequency of dosing. New avenues for targeting the condition will emerge as our knowledge of the regulatory mechanisms of bone remodelling increases, although issues of tissue specificity may be difficult to solve. In the long term, information gained through knowledge of bone genetics may be used to adapt pharmacological treatments more precisely to each individual.
Full Text Available The vast amount of research over the past decades has significantly added to our knowledge of phantom limb pain. Multiple factors including site of amputation or presence of preamputation pain have been found to have a positive correlation with the development of phantom limb pain. The paradigms of proposed mechanisms have shifted over the past years from the psychogenic theory to peripheral and central neural changes involving cortical reorganization. More recently, the role of mirror neurons in the brain has been proposed in the generation of phantom pain. A wide variety of treatment approaches have been employed, but mechanism-based specific treatment guidelines are yet to evolve. Phantom limb pain is considered a neuropathic pain, and most treatment recommendations are based on recommendations for neuropathic pain syndromes. Mirror therapy, a relatively recently proposed therapy for phantom limb pain, has mixed results in randomized controlled trials. Most successful treatment outcomes include multidisciplinary measures. This paper attempts to review and summarize recent research relative to the proposed mechanisms of and treatments for phantom limb pain.
Full Text Available Michel BilliardDepartment of Neurology, Gui de Chauliac Hospital, Montpellier, FranceAbstract: The management of narcolepsy is presently at a turning point. Three main avenues are considered in this review: 1 Two tendencies characterize the conventional treatment of narcolepsy. Modafinil has replaced methylphenidate and amphetamine as the first-line treatment of excessive daytime sleepiness (EDS and sleep attacks, based on randomized, double blind, placebo-controlled clinical trials of modafinil, but on no direct comparison of modafinil versus traditional stimulants. For cataplexy, sleep paralysis, and hypnagogic hallucinations, new antidepressants tend to replace tricyclic antidepressants and selective serotonin reuptake inhibitors (SSRIs in spite of a lack of randomized, double blind, placebo-controlled clinical trials of these compounds; 2 The conventional treatment of narcolepsy is now challenged by sodium oxybate, the sodium salt of gammahydroxybutyrate, based on a series of randomized, double-blind, placebo-controlled clinical trials and a long-term open label study. This treatment has a fairly good efficacy and is active on all symptoms of narcolepsy. Careful titration up to an adequate level is essential both to obtain positive results and avoid adverse effects; 3 A series of new treatments are currently being tested, either in animal models or in humans, They include novel stimulant and anticataplectic drugs, endocrine therapy, and, more attractively, totally new approaches based on the present state of knowledge of the pathophysiology of narcolepsy with cataplexy, hypocretine-based therapies, and immunotherapy.Keywords: narcolepsy, treatment, conventional drugs, modafinil, sodium oxybate, future treatments

Irritable Bowel Syndrome affects 9-23% of the general population. This diagnosis contributes to more frequent doctor visits and multiple consultations by patients. The current approach to treating IBS is symptomatic and consists of a regimen of first line pharmacological treatment options; the use of anti-depressant drugs is also common. The efficiency of complementary medicine in the treatment of IBS has been studied in the last few years. Qualitative multidisciplinary approach studies, using personalized medicines with complementary therapies are needed. We present the case of a 39-year-old woman with a diagnosis of IBS since 2009, who complained about gastrointestinal symptoms since the age of 13 and severe episodes of spasmodic stomach aches in the last year self-ranked as 10, on a 0-10 scale; 3-4 episodes a month, which last for 5 days, accompanied by severe flatulence and bloating. In addition, she has constipation (one bowel movement every 10 days), alternating with multiple diarrheic bowel movements (6 times a day). Using a multidisciplinary approach, including medicinal care, Chinese medicine, reflexology and naturopathy resulted in significant improvement in symptoms and quality of life, as well as gradual reduction of drugs, approved by her physician. Stomach ache self-ranked now as 1, on a 0-10 scale; and flatulence and bloating self-ranked as mild. Bowel movement frequency increased and is now every other day. She no longer has diarrheic and/or multiple bowel movements. This case report emphasizes the importance of integrative treatment in IBS and its benefit in improving patients' quality of life.

There is mounting evidence that obesity is associated with asthma, both of which are seeing a dramatic increase in prevalence. Not only is obesity a risk factor for the development of asthma but it is also associated with poor asthma control. Asthma phenotypes associated with obesity include early-onset allergic asthma and late-onset non-allergic asthma. The pathogenesis of the linkage is complex; obesity causes a variety of mechanical, metabolic, and immunological changes that can affect the airways. The treatment of asthma in obesity can be challenging, as obesity is associated with poor response to standard controller medications. A tailored approach that involves combining pharmacologic and non-pharmacologic therapies including weight loss, dietary interventions, and exercise, along with identification and treatment of obstructive sleep apnea, should therefore be considered in this population.

Approaches to treating melanoma have changed radically since the introduction of immunotherapy, and survival figures are now higher than possible with earlier therapies. The immunomodulators currently available mainly block CTLA-4 (cytotoxicT lymphocyte-associated molecule-4) and PD-1 (programed cell death protein 1) translocated to the cell surface, where they inhibit the antitumor immune response. Treatments blocking these molecules are being more widely used. Research now seeks new molecular targets, the best combinations of available drugs, and biomarkers that can identify ideal candidates for each one. Copyright © 2017 AEDV.

A quantity of up to 4000 m3/h of water is used at CERN for cooling purposes: experiments, magnets and radio frequency cavities are refrigerated by closed circuits filled with deionized water; other utilities, such as air-conditioning, use chilled/hot water, also in closed circuits. All these methods all employ a cold source, the primary supply of water, coming from the cooling towers. About 500 kCHF are spent every year on water treatment in order to keep the water within these networks in operational conditions. In the line of further rationalization of resources, the next generation of contracts with the water treatment industry will aim for improved performance and better monitoring of quality related parameters in this context. The author will provide a concise report based upon an examination of the state of the installations and of the philosophy followed up until now for water treatment. Furthermore, he/she will propose a new approach from both a technical and contractual point of view, in preparation ...

Systemic sclerosis (scleroderma) is unique among the rheumatic diseases because it presents the challenge of managing a chronic multisystem autoimmune disease with a widespread obliterative vasculopathy of small arteries that is associated with varying degrees of tissue fibrosis. The hallmark of scleroderma is clinical heterogeneity with subsets that vary in the degree of disease expression, organ involvement, and ultimate prognosis. Thus, the term scleroderma is used to describe patients who have common manifestations that link them together, whereas a highly variable clinical course exists that spans from mild and subtle findings to aggressive, life-threatening multisystem disease. The physician needs to carefully characterize each patient to understand the specific manifestations and level of disease activity to decide appropriate treatment. This is particularly important in treating a patient with scleroderma because there is no treatment that has been proven to modify the overall disease course, although therapy that targets specific organ involvement early before irreversible damage occurs improves both quality of life and survival. This review describes our approach as defined by evidence, expert opinion, and our experience treating patients. Scleroderma is a multisystem disease with variable expression; thus, any treatment plan must be holistic, yet at the same time focus on the dominant organ disease. The goal of therapy is to improve quality of life by minimizing specific organ involvement and subsequent life-threatening disease. At the same time the many factors that alter daily function need to be addressed, including nutrition, pain, deconditioning, musculoskeletal disuse, comorbid conditions, and the emotional aspects of the disease, such as fear, depression, and the social withdrawal caused by disfigurement.

The treatment train approach has been attempted in a 1.6km2 catchment in the River Eden as part of the UK Demonstration Test Catchment Project. The catchment is one of three detailed study catchments of 10km2 that are investigating diffuse pollution losses from an intense grassland farming system. The catchment is very susceptible to saturation and high losses of fine sediment and phosphorus in storm events. The poster will show how a sequence of mitigation features that target nutrient sources and flow pathways can reduce nutrient losses. 5 features have been installed from farmyard runoff control, along polluting tracks and sediment traps in the farm ditch network. Together the features can slow, store and trap sediment and pollutants. The potential to have further impacts on flood generation and drought mitigation are also being studied. Although the features are currently small in size the ability to directly reduce pollution can be demonstrated. Hence, the potential to scale up these features to a broader catchment scale can be explored and the likely costs and benefits can be simulated. This work builds upon similar work addressing flood control features, sediment trapping on farms and methods for the direct mitigation of fast polluting pathways often referred to as Nature Based Solutions. The designs and construction of the completed features will be shown in the poster. Early results show that the combined effect of the 5 features can significantly impact on sediment and pollution during storm events. The specific yield of the impact was 42 kg of suspended sediment/ha 0.06 kg P/ha of P trapped and 0.16 kg of N/ha. This mitigation impact is derived from an area of only 0.02% of the catchment. The potential to increase the mitigated area is thus large. Payment schemes for farmers could encourage the take up the of these methods and future maintenance regimes for managing the features would also have to be created. However, the potential to mitigate fast

Endometriosis continues to plague women of reproductive age. It is a chronic disease leading to a decreased quality of life, infertility, and increased societal costs. The gold standard for diagnosis remains visualization and or biopsy of lesions at the time of intraoperative diagnosis, i.e. laparoscopy or laparotomy. The severity of pain does not correlate with the stage of endometriosis, which complicates the treatment process. Hormonal therapies have long been used as a treatment for endometriosis. Therapy is targeted at symptom relief as a cure is lacking. While some regimes use hormonal therapy exclusively, others combine such with surgical excision of lesions. Although hormonal modalities are successful in alleviating or suppressing symptoms, they fail to treat the infertility associated with endometriosis. Therefore, those, desiring to achieve pregnancy should be excluded from hormonal treatment in the short term. Future studies are needed to understand the pathophysiology and allow design of specific, targeted treatment.

Aging may affect the voice through either physiological or pathological changes. Globally society is aging and the working lifetime is extending. Increasing numbers of elderly will present with voice issues. This review examines current thinking regarding surgical treatment of the aging voice. The mainstay of surgical treatment remains injection laryngoplasty and medialization thyroplasty. In-office injection laryngoplasty is increasingly common. Data suggest that patients with vocal fold atrophy do not achieve as much benefit from augmentation treatments as other causes of glottal incompetence. In addition the timing of injection laryngoplasty may influence the rate of subsequent medialization thyroplasty. Disease-specific treatments can provide some benefit to voice, such as deep brain stimulation in Parkinson's disease. Novel treatments including growth factor therapy are entering clinical practice and will provide new options for the clinician in future. Voice disorders affect approximately 20% of the elderly population. Causes include neurologic, malignant, iatrogenic and benign vocal fold disorders. These should be ruled out before accepting dysphonia is age-related in nature. Treatment should be specific to recognized vocal disorders but may also address physiologic changes in the glottis. Injection laryngoplasty and thyroplasty remain effective options for treating glottal incompetence but novel therapies are showing promising results.

Tuberculosis, commonly known as TB, is the second most fatal infectious disease after AIDS, caused by bacterium called Mycobacterium tuberculosis. Prolonged treatment, high pill burden, low compliance, and stiff administration schedules are factors that are responsible for emergence of MDR and XDR cases of tuberculosis. Till date, only BCG vaccine is available which is ineffective against adult pulmonary TB, which is the most common form of disease. Various unique antibodies have been developed to overcome drug resistance, reduce the treatment regimen, and elevate the compliance to treatment. Therefore, we need an effective and robust system to subdue technological drawbacks and improve the effectiveness of therapeutic drugs which still remains a major challenge for pharmaceutical technology. Nanoparticle-based ideology has shown convincing treatment and promising outcomes for chronic infectious diseases. Different types of nanocarriers have been evaluated as promising drug delivery systems for various administration routes. Controlled and sustained release of drugs is one of the advantages of nanoparticle-based antituberculosis drugs over free drug. It also reduces the dosage frequency and resolves the difficulty of low poor compliance. This paper reviews various nanotechnology-based therapies which can be used for the treatment of TB.

A 14-year-old boy presented with months of severe widespread musculoskeletal pain. He was profoundly fatigued and unable to attend school. Laboratory evaluation, including complete blood count, comprehensive metabolic panel, inflammatory markers, and thyroid function, was unrevealing. Physical examination was also normal except for multiple tender points. The patient was diagnosed with juvenile primary fibromyalgia syndrome and referred for multidisciplinary treatment including physical therapy, exercise, and counseling, and his daily functioning gradually improves. Juvenile fibromyalgia is a complex syndrome that often severely limits patients' activities and can impede normal adolescent development. Effective treatment requires an understanding of the biologic, psychologic, and social factors contributing to the perpetuation of chronic pain. The author reviews the diagnostic criteria, pathophysiology, and treatment of juvenile fibromyalgia. Medications, particularly antidepressants and anticonvulsants, can be useful adjuncts to therapy. However, multimodal pain management including intensive physical therapy, exercise, counseling, and sleep hygiene is most effective in treating fibromyalgia.

When pharmacologic agents are considered in the treatment of cocaine addiction, the objective of such treatment--sustained abstinence--must be considered. Medication and medical approaches have been disappointing in the treatment of cocaine overdose. The central neurobiologic mechanism(s) involved in cocaine toxicity are poorly understood. Without a cocaine antagonist, pharmacologic approaches have been less than promising in preventing relapse. Various psychoactive medications have been trie...

This review considers the various modes of action and possible advantages of the different types of second generation antidepressants. The biochemical changes that may be causally related to depression and the mechanisms whereby these changes may be attenuated by antidepressant treatment are briefly considered. Whereas the monoamine theory of depression and the receptor adaptation hypothesis of antidepressant action have been influential in helping to unify the mechanisms of action of antidepressants with the possible pathologic basis of depression, the introduction of novel antidepressants and the development of treatment strategies suggestive of a rapid onset of antidepressant response may initiate a revision of these concepts. The review ends with a consideration of the nonaminergic changes that may be of fundamental importance not only in the pathologic basis of depression but also to the means whereby antidepressants bring about their clinical effects.

The purpose of this article is to describe a model outpatient substance abuse treatment program. This program is designed to provide patients with not only traditional modalities of treatment such as individual, group, and family therapy, but also to provide an opportunity for patients to express thoughts and feelings through holistic modalities. These modalities include dance/movement therapy, Tai Chi, art therapy, leisure and recreational skills, spiritual growth and development, cultural awareness and appreciation, vocational services, psychiatric care and physical health. The authors describe features of this program that they believe to be unique and that focus on ways to help patients develop a stronger sense of self-identity, self-esteem and self-confidence.
Full Text Available Pemphigus is a bullous auto-immune disease which has high mortality and morbidity rates and affects the skin and mucosa. Corticosteroids are still the baseline treatment modality of pemphigus management. However, non-steroidal drugs and methods have been used more frequently in patients with pemphigus who are non-responders to conventional therapy or have severe side effects. In this article we aimed to review unconventional therapy modalities in patients with pemphigus.

Diabetic ketoacidosis (DKA), a common cause of severe metabolic acidosis, remains a life-threatening condition due to complications of both the disease and its treatment. This Acid-Base and Electrolyte Teaching Case discusses DKA management, emphasizing complications of treatment. Because cerebral edema is the most common cause of mortality and morbidity, especially in children with DKA, we emphasize its pathophysiology and implications for therapy. The risk for cerebral edema may be minimized by avoiding a bolus of insulin, excessive saline resuscitation, and a decrease in effective plasma osmolality early in treatment. A goal of fluid therapy is to lower muscle venous Pco2 to ensure effective removal of hydrogen ions by bicarbonate buffer in muscle and diminish the binding of hydrogen ions to intracellular proteins in vital organs (such as the brain). In patients with DKA and a relatively low plasma potassium level, insulin administration may cause hypokalemia and cardiac arrhythmias. It is suggested in these cases to temporarily delay insulin administration and first administer potassium chloride intravenously to bring the plasma potassium level close to 4mmol/L. Sodium bicarbonate administration in adult patients should be individualized. We suggest it be considered in a subset of patients with moderately severe acidemia (pH<7.20 and plasma bicarbonate level < 12mmol/L) who are at risk for worsening acidemia, particularly if hemodynamically unstable. Sodium bicarbonate should not be administered to children with DKA, except if acidemia is very severe and hemodynamic instability is refractory to saline administration.

Cocaine is a potent stimulant of the central nervous system with severe addiction potential. Its abuse is a major problem worldwide. The exact mechanism of action of cocaine is still uncertain but it is known that its reinforcing and stimulant effects are related to its ability to inhibit the membrane bound dopamine transporter (DAT). This paper discusses efforts that are underway to identify ligands for possible use in the treatment of cocaine abuse. Much of this effort has been focussed on understanding cocaine interactions at DAT receptor sites.
Full Text Available Amyloidosis is a disease marked by deposition of misfolded proteins, known as amyloids, in the extracellular space, including gastrointestinal tract. According to the precursor protein, amyloidosis is classified into six types; all of which can be involved in the gastrointestinal tract. Amyloidosis has weight loss and gastrointestinal bleeding as the most frequent symptoms. Gastrointestinal tract biopsy is diagnostic in most cases of amyloidosis and Congo red stain is used to confirm the amyloid proteins deposit. Treatment of amyloidosis consists of controlling symptoms, terminating protein formation and deposit, and treating the underlying diseases. Chemotherapy might be applied depends on the type of amyloidosis.

One of the most important reasons of infertility and human reproductive failure is related to uncontrolled immunological response of maternal immune system to early embryo or fetus, that cause rejection of this semi-allograft. Therefore, a tolerance in the immune system is essential to modulate the reactions against the fetus to avoid rejection. The immune system imbalance during implantation or pregnancy may lead to implantation failure or miscarriage. So, use of immunosuppressive or immunomodulator agents can be helpful to prevent immunological attack. Initially, there was a focus on steroids like prednisolone or intralipids in treatment of miscarriage that suppressed the activity of most immune cells, Intravenous Immunoglobulin (IVIG) was then introduced with various mechanisms. Nowadays, novel and specific strategies are established such as monoclonal antibodies and cytokines. More recently, Tacrolimus and Cyclosporine, which were utilized in prevention of transplantation reject, are used as immunosuppressive factors in modulation of immune responses against the fetus. This review is focused on the main immunotherapeutic methods of infertility treatment.
Full Text Available Jennifer Frank, David SommerfeldUniversity of Wisconsin School of Medicine and Public Health, Department of Family Medicine, Appleton, WI, USAAbstract: Resistant hypertension, defined as failure to achieve target blood pressure despite the use of optimal or maximum doses of at least 3 agents, one of which is a diuretic, or requiring 4 or more medications to achieve blood pressure goal, is likely to affect up to 20% of all patients with hypertension. Apparent resistant hypertension may be caused by medication nonadherence, substances that either interfere with antihypertensive mediations or cause blood pressure elevation, and under- or inappropriate medication treatment. Certain patient characteristics are associated with the presence of resistant hypertension and include chronic kidney disease, diabetes, obesity, and presence of end-organ damage (microalbuminuria, retinopathy, left-ventricular hypertrophy. Secondary causes of resistant hypertension are not uncommon and include obstructive sleep apnea, chronic kidney disease, primary aldosteronism, renal artery stenosis, pheochromocytoma, and Cushing’s disease. Initial medication management usually includes adding or increasing the dose of a diuretic, which is effective in lowering the blood pressure of a large number of patients with resistant hypertension. Additional management options include maximizing lifestyle modification, combination therapy of antihypertensive agents depending on individual patient characteristics, adding less-commonly used fourth- or fifth-line antihypertensive agents, and referral to a hypertension specialist.Keywords: resistant hypertension, blood pressure, diuretic

Full Text Available Differential diagnosis in muscle pains often presents great difficulties so all existing signs of the disease should be carefully considered to make its diagnosis and to prescribe adequate therapy. The paper considers the causes of muscle pains, laboratory and instrumental studies (immunological tests, determination of the level of specific muscular enzymes, primarily creatine phosphokinase – CPK, etc., and the main reasons for enhanced plasma CPK activity. It also describes acute and chronic mialgias associated with enhanced plasma CPK activity, as well as diseases in which mialgias are related to the normal level of CPK, myofascial syndrome (MFS and fibromyalgia (FM in particular. The characteristic features of MFS are given in its diagnostic criteria. It is stated that a differential diagnosis should be made between MFS and major muscle pain-associated abnormalities, such as polymyalgia rheumatica, FM, etc. Diagnosticcriteria for polymyalgia rheumatica are given. A MFS treatment algorithm is presented. Local exposure methods applied to altered musculoligamentous structures in combination with myorelaxants and non-steroidal anti-inflammatory drugs assume paramount importance in MFS.
In Japan, synthetic drugs have emerged since late 2000s, and cases of emergency visits and fatal traffic accidents due to acute intoxication have rapidly increased. The synthetic drugs gained popularity mainly because they were cheap and thought to be "legal". The Japanese government restricted not only production and distribution, but also its possession and use in April 2014. As the synthetic drug dependent patients have better social profiles compared to methamphetamine abusers, this legal sanction may have triggered the decrease in the number of synthetic drug dependent patient visits observed at Kanagawa Psychiatric Center since July 2014. Treatment of the synthetic drug dependent patients should begin with empathic inquiry into the motives and positive psychological effects of the drug use. In the maintenance phase, training patients to trust others and express their hidden negative emotions through verbal communications is essential. The recovery is a process of understanding the relationship between psychological isolation and drug abuse, and gaining trust in others to cope with negative emotions that the patients inevitably would face in their subsequent lives.

Acromegaly is a rare disease characterized by hypersecretion of growth hormone (GH), typically from a benign pituitary somatotroph adenoma, that leads to subsequent hypersecretion of insulin-like growth factor 1 (IGF-1). Patients with acromegaly have an increased risk of mortality and progressive worsening of comorbidities. Surgery, medical therapy, and radiotherapy are currently available treatment approaches for patients with acromegaly, with overall therapeutic goals of lowering GH levels and achieving normal IGF-1 levels, reducing tumor size, improving comorbidities, and minimizing mortality risk. Although surgery can lead to biochemical remission in some patients with acromegaly, many patients will continue to have uncontrolled disease and require additional treatment. We reviewed recently published reports and present a summary of the safety and efficacy of current treatment modalities for patients with acromegaly. A substantial proportion of patients who receive medical therapy or radiotherapy will have persistently elevated GH and/or IGF-1. Because of the serious health consequences of continued elevation of GH and IGF-1, there is a need to improve therapeutic approaches to optimize biochemical control, particularly in high-need patient populations for whom current treatment options provide limited benefit. This review discusses current treatment options for patients with acromegaly, limitations associated with each treatment approach, and areas within the current treatment algorithm, as well as patient populations for which improved therapeutic options are needed. Novel agents in development were also highlighted, which have the potential to improve management of patients with uncontrolled or persistent acromegaly.

Alzheimer disease, diabetes and cardiovascular diseases are among the leading causes of morbidity and mortality worldwide. Different immunotherapeutic approaches for prevention and treatment of these diseases are currently object of several researches. In this paper, recent trials describing active and passive immunotherapy for the management of these pathologies are discussed. The recent immunotherapeutic and preventive approaches for the treatment of Alzheimer's disease are based on the use of β-amyloid peptides and to tau-based immunization strategies but new possibility are explored. Immunotherapeutic vaccine against angiotensin II showed promising results for the management of hypertension. Heath shock proteins and β2-glycoprotein I have been tested to reduce atherosclerosis. Insulin agonists were used for preventing type 1 diabetes in mouse; IL-1β was effective in experimental type 2 diabetes. Research in the field of immunological approach to treatment and prevention of chronic diseases is promising even if the present results have been obtained mainly in animal models.

Background There is no single approach that provides adequate exposure for treatment of all types of acetabular fractures. We describe our experience with an easier, relatively less invasive pubic symphysis approach (PSA) for the treatment of acetabular fractures. Material/Methods Between March 2011 and March 2012, fifteen patients with acetabular fracture underwent surgery using the PSA technique. Fracture reduction and treatment outcomes were assessed by clinical and radiological examination. Operation time, intraoperative blood loss and postoperative complications were documented. Results Mean operative time was 222±78 minutes. Average blood loss was 993±361 mL. Anatomical reduction was achieved in all patients. Minimum follow-up period was 31 months. Postoperative hypoesthesia in the area of innervation of the lateral femoral cutaneous nerve was reported in one patient, with spontaneous recovery at one month after surgery. No complications were reported during the follow-up period. At the most recent follow up, clinical outcomes were graded as “excellent” in six patients, “good” in eight patients and “fair” in one patient based on the modified Merle d’Aubigné-Postel score. Conclusions PSA appears to be a timesaving and safe approach for treatment of acetabular fractures that affords good visual access and allows for excellent fracture reduction. Our preliminary results revealed a much lower incidence of complications than traditional approaches, suggesting PSA is an alternative for treatment of acetabular fractures. PMID:27734825

Long-term outcome studies have shown that schizophrenia is an illness whose course is usually characterized by exacerbations and remissions. This chapter summarizes pertinent literature regarding treatment of acute episodes; early intervention to prevent the development of full relapse; and pharmacological, behavioral, and psychotherapeutic strategies designed to decrease the amount of stress and patients' vulnerability to stress and thus decrease the likelihood of relapse. An emphasis is placed on a comprehensive treatment approach involving continuity of care.

A primary goal in dentistry is the execution of appropriate treatment plans that are minimally invasive and maintainable. However, it is sometimes necessary to repair existing dental restorations or revise treatment plans to accommodate changes in a patient's condition. In the present case, a patient who was satisfied with a removable partial overdenture lost a critical abutment tooth. A creative, minimally invasive approach enabled the patient to keep his existing partial prosthesis and avoid the need for a full reconstruction or complete denture.

The treatment of chronic hepatitis C virus (HCV) is evolving rapidly. In 2014, the standard of care and new backbone of HCV treatment is the polymerase inhibitor sofosbuvir (SOF). Our treatment approach in patients with HCV genotype 1 is 12 weeks of SOF, peginterferon (PEGINF), and ribavirin (RBV). In patients with cirrhosis or extrahepatic manifestations of HCV who cannot tolerate PEGINF, we use 12 weeks of SOF and simeprevir. The latter is less costly and more effective than SOF and RBV for 24 weeks. Our treatment approach in all patients with genotype 2 is SOF and RBV for 12 weeks. Hepatitis C virus genotype 3 is now the most costly and difficult to cure. Our approach to treatment-naive patients with genotype 3 is SOF and RBV for 24 weeks. In patients who have previously undergone PEGINF and RBV treatment, we use PEGINF, SOF, and RBV for 12 weeks, which is equally if not more effective and less costly than SOF and RBV for 24 weeks. Patients with cirrhosis who cannot tolerate PEGINF should be treated for 24 weeks with SOF and RBV, although the sustained virologic response is suboptimal.

Depression is a widespread psychological disorder that affects approximately one in five North American. Typical reactions to depression include inactivity, isolation, and rumination. Several treatments and psychological interventions have emerged to address this problematic. Cognitive behavioural therapies have received increasingly large amounts of empirical support. A sub-component of cognitive behavioural therapy, behavioural activation, has been shown to in itself effectively treat symptoms of depression. This intervention involves efforts to re-activate the depressed client by having them engage in pleasant, gratifying, leisure, social, or physical activities, thereby counteracting the tendency to be inactive and to isolate oneself. Clients are guided through the process of establishing a list of potentially rewarding social, leisure, mastery-oriented or physical activities, to then establish a gradual hierarchy of objectives to be accomplished over the span of several weeks. Concrete action plans are devised, and solutions to potential obstacles are elaborated. The client is the asked to execute the targeted objective and to record their mood prior to and following the activity. Behavioural activation effectively reverses the downward spiral to depression. Interestingly, studies show that behavioural activation has a positive effect on cognitive activities. It has been shown to reduce rumination and favour cognitive restructuring, without requiring cognitively-based interventions. The advantage of this treatment is therefore that it is simpler to administer in comparison to full-packaged cognitive behavioural therapies, it requires a lesser number of sessions and can be disseminated in a low-intensity format. This article begins by summarizing the origins of the behavioural model of depression, which serves as a basis to the understanding of behavioural activation. This is followed by a detailed explanation of the different phases involved in a behavioural

Snake venom toxins first transit the lymphatic system before entering the bloodstream. Ointment containing a nitric oxide donor, which impedes the intrinsic lymphatic pump, prolonged lymph transit time in rats and humans and also increased rat survival time after injection of venom. This pharmacological approach should give snakebite victims more time to obtain medical care and antivenom treatment.
Full Text Available Hypertension remains one of the most important medical problems in spite of significant medical advances. In many studies, both systolic and diastolic blood pressures have been found to be closely related with cardiovascular (CV morbidity and mortality. The primary aim in the treatment of hypertension is to reduce CV disease risk and the related morbidity and mortality. Hypertension is one of the most common causes of death worldwide due to its high prevalence. Because it is thought that it will be an important public health problem in the future, as it is now, the need for developing new guidelines based on new studies emerges. Individualized treatment plans based on up-to-date guidelines would be the most appropriate approach for physicians. Herein, the current approach to the treatment of hypertension has been summarized in the light of recent guidelines.
Full Text Available The conventional approach of initially treating glaucoma medically and holding surgical intervention as a reserve option was endorsed by the findings of the Collaborative Initial Glaucoma Treatment Study (CIGTS study.1 This study reported that patients had similar visual field outcomes at five years from either medical treatment or immediate filtration surgery and supported the status quo of glaucoma management. The market for medical treatments has since increased and polypharmacy is now an accepted norm for glaucoma treatment. Surgical remedies for glaucoma have existed in a less pressured environment such that trabeculectomy, after four decades of slow evolution and complications, remains the most commonly performed type of glaucoma surgery worldwide. This ecosystem has begun to change in recent years. New surgical alternatives have arrived, reached a sizeable number and gained considerable traction as viable competitors to conventional glaucoma medical and surgical treatments. This raises important questions as to how these advances in glaucoma surgical options may affect the future landscape of glaucoma treatment. Has trabeculectomy already yielded some of its high ground? Why has trabeculectomy not been able to evolve more rapidly in response to new competitive pressures? If trabeculectomy has reached its evolutionary zenith are the newer alternatives any better? And, is it time to re-examine the conventional ‘medical before surgical’ approach to glaucoma? This article reviews the evidence for current surgical techniques available to patients with glaucoma.

Five pharmaceutical strategies are currently approved by the US FDA for the treatment of obesity: orlistat, lorcaserin, liraglutide, phentermine/topiramate, and bupropion/naltrexone. The most effective treatment seems to be the combined administration of phentermine/topiramate followed by lorcaserin and bupropion/naltrexone. In relation to the management of excessive weight, other aspects also need to be considered, including comorbidities accompanying obesity, drug interactions, and the risk of negative collateral effects, as well as individualized treatments based on the genetic make-up. This review aims to provide an overview of the approved anti-obesity drugs and newer molecules that could affect different targets in the central nervous system or peripheral tissues, the molecular mechanisms, emerging dietary treatments and phytogenic compounds, and pharmacogenetic/nutrigenetic approaches for personalized obesity management.

The diagnosis of pulmonary embolism (PE) is frequently considered in patients presenting to the emergency department or when hospitalized. Although early treatment is highly effective, PE is underdiagnosed and, therefore, the disease remains a major health problem. Since symptoms and signs are non specific and the consequences of anticoagulant treatment are considerable, objective tests to either establish or refute the diagnosis have become a standard of care. Diagnostic strategy should be based on clinical evaluation of the probability of PE. The accuracy of diagnostic tests for PE are high when the results are concordant with the clinical assessment. Additional testing is necessary when the test results are inconsistent with clinical probability. The present review article represents the consensus-based recommendations of the Interdisciplinary Association for Research in Lung Disease (AIMAR) multidisciplinary Task Force for diagnosis and treatment of PE. The aim of this review is to provide clinicians a practical diagnostic and therapeutic management approach using evidence from the literature.

Effluent originating from distilleries known as spent wash leads to extensive soil and water pollution. Elimination of pollutants and colour from distillery effluent is becoming increasingly important from environmental and aesthetic point of view. Stillage, fermenter and condenser cooling water and fermenter wastewater are the primary polluting streams of a typical distillery. Due to the large volumes of effluent and presence of certain recalcitrant compounds, the treatment of this stream is rather challenging by conventional methods. Therefore, to supplement the existing treatments, a number of studies encompassing physico-chemical and biological treatments have been conducted. This review presents an account of the problem and the description of colour causing components in distillery wastewater and a detailed review of existing biological approaches. Further, the studies dealing with pure cultures such as bacterial, fungal, algal and plant based systems have also been incorporated. Also, the roles of microbial enzymes in the decolourization process have been discussed to develop a better understanding of the phenomenon.

Autoimmune hemolytic anemia (AIHA) is an infrequent group of diseases defined by autoantibody mediated red blood cell destruction. Correct diagnosis and classification of this condition are essential to provide appropriate treatment. AIHA is divided into warm and cold types according to the characteristics of the autoantibody involved and by the presence of an underlying or associated disorder into primary and secondary AIHA. Due to its low frequency, treatment for AIHA is largely based on small prospective trials, case series, and empirical observations. This review describes in detail the different treatment approaches for autoimmune hemolytic anemia. Warm antibody type AIHA should be treated with steroids, to which most patients respond, although relapse can occur and maintenance doses are frequently required. Splenectomy is an effective second line treatment and can provide long-term remission without medication. Rituximab is a useful alternative for steroid refractory patients, those requiring high maintenance doses and unfavorable candidates for surgery. Promising therapeutic modifications with this monoclonal antibody are emerging including drug combinations, lower doses, and long-term use. Primary cold agglutinin disease has been recognized as having a lymphoproliferative monoclonal origin. It is unresponsive to both steroids and splenectomy. Rituximab is currently the best therapeutic alternative for this condition, and several treatment regimens are available with variable responses.

Psychiatric illnesses are a leading cause of disability and morbidity globally. However, the preferred orally dosed pharmacological treatment options available for depression, anxiety and schizophrenia are often limited by factors such as low drug aqueous solubility, food effects, high hepatic first-pass metabolism effects and short half-lives. Furthermore, the discovery and development of more effective psychotropic agents has stalled in recent times, with the majority of new drugs reaching the market offering similar efficacy, but suffering from the same oral delivery concerns. As such, the application of nanomedicine formulation approaches to currently available drugs is a viable option for optimizing oral drug delivery and maximizing treatment efficacy. This review focuses on the various delivery challenges encountered by psychotropic drugs, and the ability of nanomedicine formulation strategies to overcome these. Specifically, we critically review proof of concept in vitro and in vivo studies of nanoemulsions/microemulsions, solid lipid nanoparticles, dendrimers, polymeric micelles, nanoparticles of biodegradable polymers and nanosuspensions, and provide new insight into the various mechanisms for improved drug performance. The advantages and limitations of current oral nanomedicine approaches for psychotropic drugs are discussed, which will provide guidance for future research directions and assist in fostering the translation of such delivery systems to the clinical setting. Accordingly, emphasis has been placed on correlating the in vitro/in vivo performance of these nanomedicine approaches with their potential clinical outcomes and benefits for patients.

Laparoscopic Nissen fundoplication is currently considered the surgical treatment of choice for gastroesophageal reflux disease (GERD) and its long-term effectiveness is above 90%. Adequate patient selection and the experience of the surgeon are among the predictive factors of good clinical response. However, there can be new, persistent, and recurrent symptoms after the antireflux procedure in up to 30% of the cases. There are numerous causes, but in general, they are due to one or more anatomic abnormalities and esophageal and gastric function alterations. When there are persistent symptoms after the surgical procedure, the surgery should be described as "failed". In the case of a patient that initially manifests symptom control, but the symptoms then reappear, the term "dysfunction" could be used. When symptoms worsen, or when symptoms or clinical situations appear that did not exist before the surgery, this should be considered a "complication". Postoperative dysphagia and dyspeptic symptoms are very frequent and require an integrated approach to determine the best possible treatment. This review details the pathophysiologic aspects, diagnostic approach, and treatment of the symptoms and complications after fundoplication for the management of GERD.

Two-thirds of all breast cancer patients with metastases have a hormone receptor (HR)-positive/human epidermal growth factor receptor 2 (HER2)-negative subtype. Endocrine therapy is the treatment of choice in these patients since in addition to its effectiveness it can also maintain the patients' quality of life over a longer term. However, 44-62% of postmenopausal patients with metastatic breast carcinoma have primary tamoxifen resistance. After 3-5 years, 30-40% of the patients receiving tamoxifen treatment develop secondary resistance. Understanding the way in which resistance develops is therefore essential for developing treatment approaches that can prevent or reverse endocrine resistance. The phosphatidylinositol 3-kinase (PI3K)/Akt/mammalian target of rapamycin (mTOR) signaling pathway plays a central role here. As a result of the numerous interactions involved, complex issues arise that need to be taken into account in the development and use of therapeutic agents. In addition, this signaling pathway is the one that most frequently undergoes mutations in breast cancer. The prognostic and predictive significance of individual mutations has not yet been fully explained, but it might provide a basis for patient selection in clinical studies. Initial research results on the use of PI3K inhibitors suggest that this may be a highly promising therapeutic approach, with an acceptable side effect profile.

Full Text Available The incidence of diabetes and the associated debilitating complications are increasing at an alarming rate worldwide. Current therapies for type 1 diabetes focus primarily on administration of exogenous insulin to help restore glucose homeostasis. However, such treatment rarely prevents the long-term complications of this serious metabolic disorder, including neuropathy, nephropathy, retinopathy, and cardiovascular disease. Whole pancreas or islet transplantations have enjoyed limited success in some individuals, but these approaches are hampered by the shortage of suitable donors and the burden of lifelong immunosuppression. Here, we review current approaches to differentiate nonislet cell types towards an islet-cell phenotype which may be used for larger-scale cell replacement strategies. In particular, the differentiation protocols used to direct embryonic stem cells, progenitor cells of both endocrine and nonendocrine origin, and induced pluripotent stem cells towards an islet-cell phenotype are discussed.

Full Text Available A disproportionate fear of vomiting, or emetophobia, is a chronic and disabling condition which is characterized by a tendency to avoid a wide array of situations or activities that might increase the risk of vomiting. Unlike many other subtypes of specific phobia, emetophobia is fairly difficult to treat. In fact, there are only a few published cases in the literature. This paper presents a case of a 46-year old woman with emetophobia in which a trauma-focused treatment approach was applied; that is, an approach particularly aimed at processing disturbing memories of a series of events which were considered to be causal in the etiology of her condition. Four therapy sessions of Eye Movement Desensitization and Reprocessing (EMDR produced a lasting decrease in symptomatology. A 3-year follow up showed no indication of relapse.

Eosinophilia is associated with a wide variety of allergic, rheumatologic, infectious, neoplastic, and rare idiopathic disorders. Clinical manifestations range from benign asymptomatic presentations to life-threatening complications, including endomyocardial fibrosis and thromboembolism. The prognosis and choice of treatment depend not only on the degree of eosinophilia and severity of organ involvement, but also on the etiology of the eosinophilia. Unfortunately, despite recent advances in molecular and immunologic techniques, the etiology remains unproven in the overwhelming majority of cases. This review presents a practical approach to the diagnosis and treatment of patients presenting with unexplained marked eosinophilia. A brief overview of the mechanisms of eosinophilia and eosinophil pathogenesis is also provided. © 2015 by The American Society of Hematology. All rights reserved.

Hypertension is a medical condition considered one of the most important public health problems in developed countries, affecting around one billion people. Therefore, the study of its mechanisms, development and treatment is a priority. Of particular interest are the multiple contributing factors, and efforts by experts to fully understand it are also important. However, studies are currently insufficient and consequently, attention is focused on the exploration of new therapeutic approaches. This raises a growing interest in nanotechnology given the ability of certain structures to mimic the behavior of extracellular matrices. This opens a promising field in the treatment of diseases such as hypertension, where it stands to tissue engineering and its potential applications incorporating concepts such as controlled release drug, reduced side effects and receptor activation locally.

Recently, various video-assisted thoracoscopic surgical techniques have been reported with occasional success in treating hepatic hydrothorax (HH). In 2 patients with refractory HH, we applied a combination of four therapeutic modalities as a single procedure named as a "four-step approach": (1) pneumoperitoneum for localization of diaphragmatic defects, (2) thoracoscopic pleurodesis, (3) postoperative continuous positive airway pressure, and (4) drainage of ascites for abdominal decompression. The treatment was successful in both patients, without recurrence during the follow-up period of 24 and 3 months, respectively.

Full Text Available Ureteral DJ stents have been used widely for years in urology practice. With increased use, complications have been increased and forgotton stents have started to cause problems. The most common complications are early pain and irritative symptoms. Late complications are bacterial colonization and stone formation because of the biofilm covering the stents. Treatment for a forgotten stent varies on many factors, such as stent localization and stone formation. In this article, we aimed to discuss our clinic approach on two different cases in light to current literature. [Cukurova Med J 2015; 40(Suppl 1: 58-63
Full Text Available François Paille, Hervé Martini Department of Addiction Treatment, University Hospital, Vandœuvre-lès-Nancy, France Abstract: Reduction of alcohol consumption is not yet a widely accepted treatment objective for alcohol-dependent patients, as abstinence is often considered to be the only possible objective in this situation. However, various studies have demonstrated the value of proposing these two options to such patients. Firstly, reduction of alcohol consumption very significantly reduces the risk of alcohol-related damage, and also modifies the patient's and the doctor's perception of the disease, resulting in improved access to care and better patient adherence with the proposed treatment objective and consequently better clinical results. Recent studies have shown that some medicinal products can help patients reduce their alcohol consumption. One such product, nalmefene, has been granted European marketing authorization and is now being released onto the market in various countries. The ESENSE 1 and 2 studies in alcohol-dependent patients showed that, in combination with BRENDA, a psychosocial intervention focusing on reinforcement of motivation and treatment adherence, nalmefene significantly reduced the number of heavy drinking days and mean daily total alcohol consumption versus placebo. This reduction was more marked in the marketing authorization target population, ie, patients with a high or very high drinking risk level according to World Health Organization criteria. Another original feature of this molecule is that it can be used as needed if the patient perceives a risk of drinking, which is a more flexible approach and more likely to ensure the patient's active involvement in the treatment of his/her disease. This molecule opens up interesting and original therapeutic prospects in the treatment of alcohol dependence.

Full Text Available Sleep disorders have a negative impact on the quality of life and contribute to physical and mental health problems. Insomnia is a pervasive condition with various causes, manifestations, and health consequences. Even though it can be triggered by a variety of precipitating events, psychological and behavioral factors are almost always involved in perpetuating or exacerbating it over time, and lead to chronic condition. This article reviews some basic models and mechanisms of chronic insomnia as well as the rationale and objectives of cognitive-behavioral therapy (CBT in its management. CBT is a safe and effective treatment that may be used either as a monotherapy or to augment therapy with drugs. Evidence from controlled clinical trials indicates that the majority of patients (70 % to 80 % with persistent insomnia respond to this treatment, which is comparable to medication treatment. Aside from the clinically measurable changes, this therapy system enables patients to regain a feeling of control over their sleep, thereby reducing the emotional distress that sleep disorders cause. But despite the evidence for effectiveness and efficacy of these therapies and also the preference for non-pharmacological treatments expressed by many patients, psychological and behavioral approaches still remain underutilized by health care practitioners. Thus, an important challenge for the future is to disseminate these evidence-based therapies more effectively and increase their routine use in clinical practice.

Hospital practitioners are regularly facing treatment-resistant depression, which may be defined according to the clinical picture or according to the therapeutic strategy. There are different levels of resistance and different levels of evidence for this resistance. Indeed, the notions of relative and absolute resistance describe the adequacy of assigned treatment. It thus seems necessary to specify the psychopathology of treatment-resistant depression and to highlight the endogeneity phenomenon in order to solve this problem. Our work addresses the concept of endogeneity (previously clarified by Hubertus Tellenbach) and will consider its implications in the management of treatment-resistant depression. We attempt to demonstrate that the phenomenological approach is an interesting tool in clinical practice through the highlight of endogenous characteristics. The first step consists in specifying the endogenous phenomena: abolition of rhythms, loss of the forward-looking deployment, overall impression, and reversibility, spatial and temporal characteristics from the phenotype. Our phenomenological approach continues by exploring the false resistances. Hence, we take into account anxious comorbidity, medical comorbidity, addictions, personality disorders and the hypothesis of a bipolar diathesis. First of all, it is difficult to show the patient in which way their behaviour results in stagnation. Indeed, it could strengthen the internal move that leads to an imperious necessity to cope with the surroundings. The psychotherapeutic help is elaborated by specifically highlighting the pathogenic situations whilst also taking into account the difficulties of an authentic therapeutic alliance. Our approach emphasizes the endogeneity phenomenon in depression, permitting the search for an optimal therapeutic strategy. It also provides assistance in resolving false resistance or what is apparent. In cases of endogenous depression, therapeutic orientation favours

BACKGROUND: Hepatocellular carcinoma (HCC) is a com-plex and heterogeneous malignancy, frequently occurs in the setting of a chronically diseased organ, with multiple con-founding factors making its management challenging. HCC represents one of the leading causes of cancer-related mortal-ity globally with a rising trend of incidence in some of the de-veloped countries, which indicates the need for better surgical and nonsurgical management strategies. DATA SOURCES: PubMed database was searched for relevant articles in English on the issue of HCC management. RESULTS: Surgical resection represents a potentially cura-tive option for appropriate candidates with tumors detected at earlier stages and with well-preserved liver function. The long-term outcome of surgery is impaired by a high rate of recurrence. Surgical approaches are being challenged by local ablative therapies such as radiofrequency ablation and micro-wave ablation in selected patients. Liver transplantation offers potential cure for HCC and also correction of underlying liver disease, and minimizes the risk of recurrence, but is reserved for patients within a set of criteria proposed for a prudent allocation in the shortage of donor organs. Transcatheter locoregional therapies have become the palliative standard allowing local control for intermediate stage patients with noninvasive multinodular or large HCC who are beyond the potentially curative options. The signiifcant survival beneift with the multikinase inhibitor sorafenib for advanced HCC has shifted the direction of research regarding systemic treat-ment toward molecular therapies targeting the disregulated pathways of hepatocarcinogenesis. Potential beneift is sug-gested from simultaneous or sequential multimodal therapies, and optimal combinations are being investigated. Despite the striking progress in preclinical studies of HCC immuno-therapy and gene therapy, extensive clinical trials are required to achieve successful clinical applications

Full Text Available The life expectancy in the Western world is increasing for a long time, which is the courtesy of a higher life standard, a more thorough hygiene, and, of course, the progress of modern medicine. Nevertheless, one of the illnesses that still proves to be a great challenge regardless of the recent advancements in medicine is cancer. Skin cancer is, according to the World Health Organization, the most common malignancy for the white population. The beginning of the paper offers a brief overview of the latest available information concerning epidemiology, aetiology, diagnostics, and treatment options for skin cancer, whereas the rest of the article deals with modern approaches to skin cancer treatment, highlighting recent development of nanotechnology based treatment approaches. Among these, we focus especially on the newest nanotechnological approaches combined with chemotherapy, a field which specialises in target specificity, drug release control, and real time monitoring with the goal being to diminish unwanted side effects and their severity, achieving a cheaper treatment and a generally more efficient chemotherapy. The field of nanotechnology is a rapidly developing one, judging by already approved clinical studies or by new theranostic agents that combine both the therapeutic and diagnostic modalities.

Full Text Available Breast cancer (BC ranks first in the pattern of female malignancies (20.7 % and remains the top cancer among women. Paget’s disease (PD is a rare BC form that occurs in the orifice of the lactiferous tubes and that is characterized by involvement of the nipple, large ducts, often to form a lump in the breast; this rare abnormality is encountered in 0.5–5 % of all BC cases. PD has a number of peculiarities. According to different authors, PD is attended with invasive or noninvasive BC in most cases (90–98 %. The involvement is commonly multifocal. PD has a very high risk for a lump (100 and 96 % for palpable and nonpalpable breast tumors, respectively. Almost 50 % of these patients have palpable breast lumps. Despite the fact that the course of PD has its peculiarities because of the rarity of this abnormality, the approaches to its treatment are not different from those in other histopathological types of BC. As for the surgical treatment of PD, until the present time there have been many unsolved problems that remain a matter of debate. The surgical treatment of PD does not differ from the treatment of BC and is primarily determined by disease stage and tumor subtype. The volume of operations for PD varies: from Madden’s radical mastectomy to lumpectomy and sentinel lymph node biopsy. It should be kept in mind that besides nipple-areole complex involvement, invasive or noninvasive BC is often detected in PD. Organ-sparing surgery for PD is mainly a method of rehabilitation for patients. Whether organsparing surgery can be performed is also determined by breast size. Oncoplaplastic resections may be carried out for PD. If the patient wishes to preserve her breast, the range of both single-stage and delayed reconstructive operations is wide. The assessment of the biological features of a tumor and the more differentiated approach to therapy in this cohort of patents might improve considerable survival rates; the determination

Psychiatry research has long experienced a stagnation stemming from a lack of understanding of the neurobiological underpinnings of phenomenologically defined mental disorders. Recently, the application of computational neuroscience to psychiatry research has shown great promise in establishing a link between phenomenological and pathophysiological aspects of mental disorders, thereby recasting current nosology in more biologically meaningful dimensions. In this review, we highlight recent investigations into computational neuroscience that have undertaken either theory- or data-driven approaches to quantitatively delineate the mechanisms of mental disorders. The theory-driven approach, including reinforcement learning models, plays an integrative role in this process by enabling correspondence between behavior and disorder-specific alterations at multiple levels of brain organization, ranging from molecules to cells to circuits. Previous studies have explicated a plethora of defining symptoms of mental disorders, including anhedonia, inattention, and poor executive function. The data-driven approach, on the other hand, is an emerging field in computational neuroscience seeking to identify disorder-specific features among high-dimensional big data. Remarkably, various machine-learning techniques have been applied to neuroimaging data, and the extracted disorder-specific features have been used for automatic case-control classification. For many disorders, the reported accuracies have reached 90% or more. However, we note that rigorous tests on independent cohorts are critically required to translate this research into clinical applications. Finally, we discuss the utility of the disorder-specific features found by the data-driven approach to psychiatric therapies, including neurofeedback. Such developments will allow simultaneous diagnosis and treatment of mental disorders using neuroimaging, thereby establishing 'theranostics' for the first time in clinical

This case presentation is about an 88 years-old male patient with previous endovascular aortic aneurysm repairment history and aortic endoleak type II (EL2). The direct lumbar artery catheterization was considered an alternative to solve EL2, associated with aortic endovascular prosthesis and due to an incomplete sealing or exclusion of the aneurysmal sac or a vascular segment demonstrated by imaging studies, when other treatment alternative failed (transarterial embolization) to control the aneurysm growing. Performing translumbar approach was decided by puncturing the artery lumbar (L4) left, previously the lumbar arteries (L4) were evaluated in the abdominal CT arterial phase to guide a puncture/access under flouroscopy control. Diagnostic angiogram clearly demonstrated the median sacral and right lumbar arteries inflow into the aneurysm sac. Transcatheter embolization with fibered platinum microcoils was performed of the median sacral artery and lumbar left and right arteries (L4), showing satisfactory endoleak devascularization.
Full Text Available Unlike the common distal humeral fracture in children, the prevalence of fractures at this site is not high in adults and accounts for only 2% of all fractures.Moreover, intraarticular fractures, especially the type C fracture, are rare and usually caused by high energy injury. After fractures occur, there are problems of disconnection between the condyles and diaphysis, and of disruption between the medial and lateral condyles. The two condyle fragments rotate along their own axes and the trochlea is usually intact. All these factors create difficulties for reduction and fixation. The currently employed surgical approaches are usually not able to provide enough exposure, and sufficient stability can not be achieved by internal fixation to allow early functional exercises. There are still difficulties in the management of intra-articular fractures of the distal humerus in adults.1, 2 Our objective is to study the surgical treatment for distal humeral fractures in adults by patients’ follow-up.

In the past decade, notable advances have been made with regard to understanding the clinical, biological and epidermological aspects of the basic disorders of development (TPD), particularly autism. Nevertheless, our knowledge of the neurobiological basis is still limited. This has impeded the development of drugs which correct the defect and cure the illness. Although there is no perfect drug, in recent years clinico-pharmacological research has made it possible to use drugs which have been very helpful in correcting the symptoms associated with these disorders. These drugs have permitted a better therapeutic approach and improved family and social integration of these children (in the family and in society). We will proceed to analyze some of the drugs shown to be useful for treatment of children with TPD.

Full Text Available Antibiotic treatment of tularaemia is based on a few drugs, including the fluoroquinolones, the tetracyclines and the aminoglycosides. Because no effective and safe vaccine is currently available, tularaemia prophylaxis following proven exposure to F. tularensis also relies on administration of antibiotics. A number of reasons make it necessary to search for new therapeutic alternatives: the potential toxicity of first-line drugs, especially in children and pregnant women; a high rate of treatment relapses and failures, especially for severe and/or suppurated forms of the disease; and the possible use of antibiotic-resistant strains in the context of a biological threat. This review presents novel therapeutic approaches that have been explored in recent years to improve tularaemia patients’ management and prognosis. First, the activities of newly available antibiotic compounds were evaluated against F. tularensis, including tigecycline (a glycylcycline, ketolides (telithromycin and cethromycin and fluoroquinolones (moxifloxacin, gatifloxacin, trovafloxacin and grepafloxacin. The liposome delivery of some antibiotics was evaluated. The effect of antimicrobial peptides against F. tularensis was also considered. Other drugs were evaluated for their ability to suppress the intracellular multiplication of F. tularensis. The effects of the modulation of the innate immune response (especially via TLR receptors on the course of F. tularensis infection were characterized. Another approach was the administration of specific antibodies to induce passive resistance to F. tularensis infection. All of these studies highlight the need to develop new therapeutic strategies to improve the management of patients with tularaemia. Many possibilities exist, some unexplored. Moreover, it is likely that new therapeutic alternatives that are effective against this intracellular pathogen could be, at least partially, extrapolated to other human pathogens.

Aim - to develop effective treatment approaches to lagophthalmos-associated neuroparalytic keratitis. A total of 34 patients (36 eyes) with neuroparalytic keratitis were enrolled. Group 1 consisted of 20 patients (21 eyes), in whom autoconjunctivoplasty was performed in combination with eyelid surgery. Group 2 consisted of 12 lagophthalmic patients (13 eyes) with purulent corneal ulcers, who additionally underwent corneal transplantation. Group 3 included 2 patients (2 eyes) with central corneal ulcer in the only seeing eye, who received, besides other things, upper sector iridectomy intended to serve as a pupil (RU 2299048 with priority date of 15.07.2005). In group 1, corneal re-epithelization and complete recovery was achieved in all patients within 3.00±0.69 weeks. Visual acuity (VA) has generally increased over the first year after treatment from 0.14±0.06 to 0.25±0.13 in group 1 and from 0.09±0.05 to 0.21±0.13 in group 2. In group 3, sector iridectomies also yielded an increase in VA - from 0.01 to 0.02 in one case and from 0.2 to 0.6 in the other. Autoconjunctivoplasty enabled rapid and stable re-epithelization of corneal defects in all cases. One-stage corneal and eyelid surgery has been shown to be more effective in treating lagophthalmos-associated neuroparalytic keratitis than previous methods. The novel approach ensures acute symptoms of keratitis resolve and the eye is saved, moreover, it allows to maintain visual acuity and prevent recurrences in 64% and 65% of patients, respectively.

In the past three decades, researchers have been attempting to replace the obsolete concept of homogeneity of alcohol dependence, by classifying these patients into specific heterogeneous subtypes. Based on 30 years of experience and research, the Lesch Typology has proved to be very useful in clinical daily routine. The aim of the Lesch Typology is to provide targeted subtype-specific treatments to patients, thereby increasing their probability of long-term abstinence and hence improving their prognosis. The Lesch Typology is based on data from a longitudinal prospective study (with follow ups even 19 years later) on alcohol dependent patients (n=436). By observing the long term development of these patients, four distinct courses could be identified. In the meantime, a computerized version of the Lesch Typology had been created and translated into many languages, and is currently being employed in numerous psychiatric institutions while assisting clinicians in quickly determining a patient's subtype (www.lat-online.at). Based on the patients' drinking patterns and origin of substance craving, hence according to the Lesch Typology, four subtypes of alcohol dependent patients can be distinguished: 1. the "allergy model" (craving caused by alcohol); 2. the "conflict resolution and anxiety model" (craving caused by stress); 3. the "depressive model" (craving caused by mood); and 4. the "conditioning model" (craving caused by compulsion). Pharmacological treatments are not always the most effective way of preventing relapses in alcohol dependent patients. Many times, a combination with psychosocial as well as psychotherapeutic approaches is necessary and essential for helping patients to stay sober. Depending on the patient's Lesch Type, certain therapeutic approaches are more appropriate and subsequently lead to better results and higher chances of lasting abstinence.

Unlike carotid bifurcation atherosclerotic stenosis, supra-aortic trunks (SAT) occlusive disease is rare and its revascularization uncommon, accouting for less than 10% of the operations performed on the extracranial brain-irrigating arteries. There are three different treatment approaches: transthoracic, extra-anatomic cervical and endovascular. Endovascular repair is gaining popularity as first-line therapy for proximal lesions with favorable anatomy because of its low morbidity and rare mortality. Extra-anatomic bypass is a safe and durable reconstruction and should be considered in patients with single vessel disease, with cardiopulmonary high-risk or with limited life expectancy. If cardiac surgery is needed, central transthoracic reconstruction is preferable, and the two procedures should be combined. The long-term patency of bypasses with aortic origin, specially when multiple vessels are involved, is superior to other repair techniques. We present three clinical cases that illustrate each of these therapeutic strategies: central brachiocephalic revascularization and synchronous cardiac surgery in a patient with complex SAT atherosclerosis disease; subclavian-carotid transposition for disabling upper limb claudication; and subclavian artery stenting for subclavian-steal syndrome. Surgical approach selection should be based on the individual patient's anatomy and operative risk.

Full Text Available Background: Thoracic outlet syndrome comprises a wide spectrum of disorders with different compressive pathologies attributed to the neurovascular bundle passing from the root of the neck to supply the upper extremity. New concepts and advances in diagnosis and treatment are emerging. This study evaluates effectiveness and safety of the supraclavicular approach in management of neurovascular compression at the thoracic outlet. Materials and Methods: Twenty patients (15 females and 5 males with mean age of 20 years (ranging from 18 to 40 years underwent anterior neurovascular decompression procedures because of symptoms of lower plexus compression (C8 - T1. Preoperative plain radiography, MRI and nerve conduction velocity studies confirmed the clinical diagnosis. Nine patients had neck pain, all had sensory deficit and eight had motor deficit. Results: After 35 months of follow-up, 17 patients showed excellent results, two cases had good results and one case had fair results according to the visual analog scale, and nerve conduction velocities. Conclusions: We recommend nerve conduction velocity studies beside clinical assessment for diagnosis and follow-up, and supraclavicular approach in neurogenic decompression which is relatively safe and effective.

There is emerging evidence that individuals with drug addiction have dysfunctions in brain systems that are important for interoceptive processing, which include, among others, the insular and the anterior cingulate cortices. These individuals may not be expending sufficient neural resources to process perturbations of the interoceptive state but may exert over-activation of these systems when processing drug-related stimuli. As a consequence, insufficient detection and processing of interoceptive state changes may result in inadequate anticipation and preparation to adapt to environmental challenges, e.g., adapt to abstinence in the presence of withdrawal symptoms. Here, we integrate interoceptive dysfunction in drug-addicted individuals, with the neural basis for meditation and exercise to develop a heuristic to target the interoceptive system as potential treatments for drug addiction. First, it is suggested that mindfulness-based approaches can modulate both interoceptive function and insular activation patterns. Second, there is an emerging literature showing that the regulation of physical exercise in the brain involves the insula and anterior cingulate cortex and that intense physical exercise is associated with a insula changes that may provide a window to attenuate the increased interoceptive response to drug-related stimuli. It is concluded that the conceptual framework of interoceptive dysfunctions in drug addiction and the experimental findings in meditation and exercise provide a useful approach to develop new interventions for drug addiction.
Full Text Available Many sewage waste treatment systems are aiming for complete pathogen removal which necessitates search for novel approaches that does not harm the environment. One such novel approach is exploring the possibilities of bacteriophages for pathogen removal. Hospital wastewater was collected from different locations of Tamil Nadu and used for the study. The total heterotroph and total coliform population ranged from 1.6 × 105 to 8.3 × 106 per mL and from 1.2 × 103 to 1.6 × 103/ 100 mL of sample respectively. Higher frequency of antibiotic resistant E. coli, Pseudomonas sp. Streptococcus sp and Bacillus spp were observed in all the places, which clearly indicated the extent of pollution. All the samples had specific phages against E. coli and none of the samples had phages against MTCC culture. E. coli specific phage was isolated and the population of phage required for effective killing of E. coli has been standardized as 3 × 104 pfu / mL of lysate. The inoculation resulted in 100% removal of pathogen from sewage water within 14 hours of incubation.

Despite significant improvements in medical management of inflammatory bowel disease,many of these patients still require surgery at some point in the course of their disease.Their young age and poor general conditions,worsened by the aggressive medical treatments,make minimally invasive approaches particularly enticing to this patient population.However,the typical inflammatory changes that characterize these diseases have hindered wide diffusion of laparoscopy in this setting,currently mostly pursued in high-volume referral centers,despite accumulating evidences in the literature supporting the benefits of minimally invasive surgery.The largest body of evidence currently available for terminal ileal Crohn's disease shows improved short term outcomes after laparoscopic surgery,with prolonged operative times.For Crohn's colitis,high quality evidence supporting laparoscopic surgery is lacking.Encouraging preliminary results have been obtained with the adoption of laparoscopic restorative total proctocolectomy for the treatment of ulcerative colitis.A consensus about patients' selection and the need for staging has not been reached yet.Despite the lack of conclusive evidence,a wave of enthusiasm is pushing towards less invasive strategies,to further minimize surgical trauma,with single incision laparoscopic surgery being the most realistic future development.
Full Text Available Aim: Phyllodes tumors of the breast are a rarely encountered clinical condition. Recurrent cases are even rarer. Treatment protocols vary among breast centers. In our study, we aimed to investigate the prognosis of recurrent breast phyllodes tumors and to present our treatment approach. Methods: Among 31000 patients, who presented to our breast outpatient clinic between March 2005 and December 2011, we retrospectively evaluated three patients with recurrent phyllodes tumors of the breast. Results: The three female patients, aged 24, 28 and 30 years, had been previously operated for phyllodes tumor of the breast. The first tumor localization was the superolateral part of the right breast in all subjects. Recurrences were in the same localizations, but pathologies were more aggressive than the previous reports. In two patients mastectomy and in one breast-conserving surgery were performed. Conclusion: Relapse of phyllodes tumors can result in mastectomy and recurrent phyllodes tumors seem to be more aggressive than the original tumor.

Autism spectrum disorder (ASD) is characterized by deficits in sociability and communication, and increased repetitive and/or restrictive behaviors. While the etio-pathogenesis of ASD is unknown, clinical manifestations are diverse and many possible genetic and environmental factors have been implicated. As such, it has been a great challenge to identify key neurobiological mechanisms and to develop effective treatments. Current therapies focus on co-morbid conditions (such as epileptic seizures and sleep disturbances) and there is no cure for the core symptoms. Recent studies have increasingly implicated mitochondrial dysfunction in ASD. The fact that mitochondria are an integral part of diverse cellular functions and are susceptible to many insults could explain how a wide range of factors can contribute to a consistent behavioral phenotype in ASD. Meanwhile, the high-fat, low-carbohydrate ketogenic diet (KD), used for nearly a century to treat medically intractable epilepsy, has been shown to enhance mitochondrial function through a multiplicity of mechanisms and affect additional molecular targets that may address symptoms and comorbidities of ASD. Here, we review the evidence for the use of metabolism-based therapies such as the KD in the treatment of ASD as well as emerging co-morbid models of epilepsy and autism. Future research directions aimed at validating such therapeutic approaches and identifying additional and novel mechanistic targets are also discussed. PMID:28270747

Based on their tumor tropism, mesenchymal stem cells (MSCs) have been proposed as carriers of cytotoxic molecules in pioneering strategies of anti-cancer gene therapy. Similar to solid tumors, MSCs, genetically modified to stably express the TNF-related apoptosis-inducing ligand (TRAIL), have been applied to counter-attack multiple myeloma (MM) in vitro and envisioned as a promising strategy for future anti-MM treatments. Accumulating evidence based on the detection of genetic and functional abnormalities in MSCs from MM patients points to the supportive function of MSCs in both the development and progression of MM, driven by chronic interplays with malignant cells within the marrow milieu. In this review, we revisit the function of MSCs in the pathophysiology of MM and explore the pivotal mechanisms of their interaction with myeloma cells. We also discuss the therapeutic significance of novel strategies using TRAIL-engineered MSCs in this cancer model, dissecting their role as new tools for future treatments against MM. A cytotherapy based on TRAIL-engineered MSCs against MM may be successfully combined with either conventional approaches of autologous stem cell transplantation or with novel anti-MM drugs. Intensive preclinical investigations are required to identify the best sources as well as modalities of MSC administration, thus defining the translational suitability of this strategy in the clinical setting.

Full Text Available Wai Tong Chien, Annie LK Yip School of Nursing, Faculty of Health and Social Sciences, The Hong Kong Polytechnic University, Hung Hom, Kowloon, Hong Kong Abstract: During the last three decades, an increasing understanding of the etiology, psychopathology, and clinical manifestations of schizophrenia spectrum disorders, in addition to the introduction of second-generation antipsychotics, has optimized the potential for recovery from the illness. Continued development of various models of psychosocial intervention promotes the goal of schizophrenia treatment from one of symptom control and social adaptation to an optimal restoration of functioning and/or recovery. However, it is still questionable whether these new treatment approaches can address the patients' needs for treatment and services and contribute to better patient outcomes. This article provides an overview of different treatment approaches currently used in schizophrenia spectrum disorders to address complex health problems and a wide range of abnormalities and impairments resulting from the illness. There are different treatment strategies and targets for patients at different stages of the illness, ranging from prophylactic antipsychotics and cognitive–behavioral therapy in the premorbid stage to various psychosocial interventions in addition to antipsychotics for relapse prevention and rehabilitation in the later stages of the illness. The use of antipsychotics alone as the main treatment modality may be limited not only in being unable to tackle the frequently occurring negative symptoms and cognitive impairments but also in producing a wide variety of adverse effects to the body or organ functioning. Because of varied pharmacokinetics and treatment responsiveness across agents, the medication regimen should be determined on an individual basis to ensure an optimal effect in its long-term use. This review also highlights that the recent practice guidelines and standards have

Full Text Available Cancer is one of the leading causes of death among the human race. No valid modalities of treatment other than surgical treatment have been established for this disease. We aimed to identify and to characterize cancer using large number of human monoclonal antibodies (mAbs which are specific against their surface for new molecular targeted immunotherapy. In order to find proper targets for therapeutic antibodies against cancers we developed a screening strategy. We used a huge phage library of human antibodies. At the first step we comprehensively isolated many monoclonal antibodies (mAbs that specifically bound to surface of cancer cells. Development of ICOS (Isolation of antigen/antibody complexes through organic solvent method allowed us to succeed in isolation of a huge number of mAbs with various characteristics (Y Akahori et al. 2009. At the next step we selected clones that showed tumor-specific staining patterns in immunohistochemical (IHC analysis by using many fresh cancer tissues reseted. Many surgeons took part in this project. Finally the antigens recognized by these clones were identified by immunoprecipitation (IP followed by analysis with mass (MS spectrometry (G Kurosawa et al. 2009. We have succeeded in identification of 29 tumor-associated antigens (TAAs and in isolation of 441 human mAbs that specifically bound to one of the 29 TAAs (G Kurosawa et al. 2008. In these screenings of the library, rounds of the selection process, mixing of cells and phage particles centrifugation growth of phages, were repeated three to four times in each screening. Therefore, numbers of phages of the clones whose antigens were abundantly present on the cell surface increased during the screenings. Recently we developed a new method for isolation of clones whose antigens were less abundantly present on the cell surface. Hence, we would like to talk on these methodology and discuss regarding this “A novel antibody based approach to Cancer

All inflammatory changes in the vessel wall are defined as vasculitis. Pediatric vasculitis may present with different clinical findings. Although Henoch-Schönlein purpura which is the most common pediatric vasculitis generally recovers spontaneously, it should be monitorized closely because of the risk of renal failure. Although Kawasaki disease is easy to diagnose with its classical findings, the diagnosis may be delayed in case of incomplete Kawasaki disease. Kawasaki disease should be considered especially in infants in case of prolonged fever even if the criteria are not fully met and intravenous immunoglobulin treatment should be administered without delay in order to prevent development of coronary artery aneurism. Reaction at the site of administration of Bacillus Calmette-Guerin (BCG) vaccine may be observed as commonly as cervical lymphadenopathy in Kawasaki disease and may be used as a valuable finding in suspicious cases. Although anti-neutrophil cytoplasmic antibody-associated vasculitides are rare in children, renal involvement is more common and progression is more severe compared to adults. Hence, efficient and aggressive treatment is required. Takayasu's arteritis is observed commonly in young adult women and rarely in adolescent girls. Therefore, a careful physical examination and blood pressure measurement should be performed in addition to a detailed history in daily practice. In children with unexplained neurological findings, cerebral vasculitis should be considered in the absence of other systemic vasculitides and necessary radiological investigations should be performed in this regard. This review will provide an insight into the understanding of pediatric vasculitis, current diagnostic approaches and prognosis by the aid of new studies.
Full Text Available Introduction. Intrauterine growth restriction (IUGR is a leading cause of perinatal morbidity and mortality due to placental insufficiency. Currently, one of the new approaches to treating this disease is the injection of nutrients to the fetus through intravascular port-systems (catheters.Objective. To assess the impact of nutrient injections as treatment to fetuses with severe growth retardation.Materials and methods. Pregnant women with IUGR (abdominal circumference (AC < 5th percentile with the absence of diastolic flow in the umbilical artery and a fetal gestational age of less than 30 weeks were randomly divided into two groups. The treatment group included six pregnant women who had an intravascular port-system for the infusion of nutrients (amino acids and glucose in the umbilical vein of the fetus for 14 ± 3 days. The control group consisted of eight patients who received only traditional dynamic monitoring and delivery at the optimum time of pregnancy. Fetal status was assessed using ultrasound equipment Accuvix V20 (Medison, South Korea by examining indicators of biometry and Doppler study of blood flow in utero, umbilical arteries, middle cerebral artery, and ductus venosus with fetal vascular resistance index calculation - pulsatility index (PI. Criteria for blood flow disturbances in the vessels were considered PI values above normal values for their gestational age, which were defined as absence or reverse blood flow in a diastole in the umbilical artery.Results. In a comparative analysis of the two groups, the treatment led to a 44.7% increase in AC of the fetus (121.0 ± 11.5 mm and 219.3 ± 18.3 mm, respectively, p ˂ 0.001. In all cases, the profile of blood flow in the umbilical artery had a positive diastolic component. As a result, there was a 45.3% decrease in PI in the umbilical artery (2.14 ± 0.54 and 1.17 ± 0.15, respectively, p < 0.05. Average fetal weight in the study group was not significantly higher than the

Full Text Available Reed bed system for wastewater treatment has been proven to be effective and sustainable alternative for conventional wastewater treatment technologies. Use of macrophytes to treat wastewater is also categorized in this method. This new approach is based on natural processes for the removal of different aquatic macrophytes such as floating, submerged and emergent. Macrophytes are assumed to be the main biological components of wetlands. These techniques are reported to be cost effective compared to other methods. Various contaminants like total suspended solids, dissolved solids, electrical conductivity, hardness, biochemical oxygen demand, chemical oxygen demand, dissolved oxygen, nitrogen, phosphorous, heavy metals, and other contaminants have been minimized using aquatic microphytes. In this paper, role of these plant species, origin and their occurrence, ecological factors and their efficiency in reduction of different water contaminants have been presented.

Mucopolysaccharidosis VI is caused by accumulation of the glycosaminoglycan dermatan sulfate in all tissues due to decreased activity of the enzyme arylsulfatase B. Patients exhibit multisystemic signs and symptoms in a chronic and progressive manner, especially with changes in the skeleton, cardiopulmonary system, cornea, skin, liver, spleen and meninges. Patients usually have normal intelligence. In the past, treatment of mucopolysaccharidoses was limited to palliative medical care. The outcome for affected patients improved with the introduction of new technologies as hematopoietic stem cell transplantation, relegated to specific situations after enzyme replacement therapy (ERT) became available. The specific ERT for MPS VI, galsulfase (Naglazyme®, Biomarin Pharmaceutical) was approved in 2005 by FDA and in 2006 by EMEA, and three clinical studies including 56 patients have evaluated the efficacy and safety. Long-term follow up data with patients treated up to 5 years showed that ERT is well tolerated and associated with sustained improvements in the patients' clinical condition. Intrathecal ERT may be considered in situations of high neurosurgical risk but still it is experimental in humans, as is intra-articular ERT. It is possible that the full impact of this therapy will only be demonstrated when patients are identified and treated soon after birth, as it was shown that early introduction of ERT produced immune tolerance and improved enzyme effectiveness in the cat model. New insights on the pathophysiology of MPS disorders are leading to alternative therapeutic approaches, as gene therapy, inflammatory response modulators and substrate reduction therapy.

Degenerative lung diseases such as chronic obstructive pulmonary disease (COPD) are common with huge worldwide morbidity. Anti-inflammatory drug development strategies have proved disappointing and current treatment is aimed at symptomatic relief. Only lung transplantation with all its attendant difficulties offers hope of cure and the outlook for affected patients is bleak. Lung regeneration therapies aim to reverse the structural and functional deficits in COPD either by delivery of exogenous lung cells to replace lost tissue, delivery of exogenous stem cells to induce a local paracrine effect probably through an anti-inflammatory action or by the administration of small molecules to stimulate the endogenous regenerative ability of lung cells. In animal models of emphysema and disrupted alveolar development each of these strategies has shown some success but there are potential tumour-inducing dangers with a cellular approach. Small molecules such as all-trans retinoic acid have been successful in animal models although the mechanism is not completely understood. There are currently two Pharma-sponsored trials in progress concerning patients with COPD, one of a specific retinoic acid receptor gamma agonist and another using mesenchymal stem cells.

We sought to evaluate the impact of race on treatment approaches and mortality following arterial trauma. The National Trauma Data Bank (version 7.2, American College of Surgeons) was queried from 2002 to 2012 to identify patients aged 18 to 65 years with arterial trauma. The association between race (white, black, and Hispanic) and mortality following arterial injury was assessed, stratified by penetrating or blunt injury. Temporal trends in the use of open and endovascular procedures were evaluated across the racial groups. Multivariable regression models adjusting for patient demographics, injury severity, hospital characteristics, insurance status, and type of intervention performed were used to evaluate potential contributors to the association of race with mortality. The study cohort consisted of 58 626 patients (52% white, 31% black, and 17% Hispanic). A majority (57%) of patients had penetrating injuries, with black and Hispanic patients being more likely to sustain penetrating injuries (80% and 65%, respectively) compared to white patients (41%, P trauma. This finding was similar across all groups studied. In multivariable analysis, black race was found to be associated with higher mortality compared to white for both penetrating (odds ratio [OR] 1.52, 95% confidence interval [CI] 1.33-1.75, P trauma. Even after adjusting for potential confounders, minority patients had increased odds of mortality following arterial trauma compared to their white counterparts. Further studies are needed to understand and to eliminate these observed disparities in outcome. © The Author(s) 2015.

The prompt neutron emission in spontaneous fission of 252Cf has been investigated applying digital signal electronics along with associated digital signal processing algorithms. A new mathematical approach, applicable to single events, was developed for prompt fission neutron (PFN) time-offlight distribution unfolding. The main goal was to understand the reasons of the long existing discrepancy between theoretical calculations and the measurements of prompt fission neutron (PFN) emission dependence on the total kinetic energy (TKE) of the fission fragments (FF). Since the 252Cf (sf) reaction is one of the main references for nuclear data the understanding of the PFN emission mechanism is very important both for nuclear fission theory and nuclear data. The experimental data were taken with a twin Frisch-grid ionization chamber and a NE213-equivalent neutron detector in an experimental setup similar to the well known work of C. Budtz-Jorgensen and H.-H. Knitter. About 2.5 × 105 coincidences between fission fragment (FF) and neutron detector response to prompt fission neutron detection have been registered (∼ 1.6 × 107 of total recorded fission events). Fission fragment kinetic energy, mass and angular distribution, neutron time-of-flight and pulse shape have been investigated using a 12-bit waveform digitizer. The signal waveforms have been analyzed using digital signal processing algorithms. The main goal of this work was a detailed description of the prompt fission neutron treatment.

Ankylosis of temporomandibular joint is a condition in which partial or complete immobilization of mandible occurs because of fusion between mandibular condyle and skull base. This condition can be treated orthodontically, surgically, or therapeutically or by prosthodontic rehabilitation. A 10-year-old female patient presented to the Department of Oral and Maxillofacial Surgery, Gazi University Faculty of Dentistry, with limited mouth opening. She got injury in the face when she was 5 years old. Extraoral and intraoral examination findings were facial asymmetry on the left side, micrognathic mandible, and 19-mm mouth opening. After radiographic examination, ankylosis (Shawney type I) on the left side was revealed, and the patient was referred to Department of Orthodontics. After orthodontic clinical examination, we create following multidisciplinary treatment approach: (1) acrylic posterior bite block with spring application, (2) interpositional arthroplasty operation, and (3) physiotherapy (passive mouth-opening exercises). After the follow-up of 9 months, significant improvement (5 mm) was noticed in the opening of the mouth, and we decided to remove appliance and operate on the patient. Surgical procedure was performed under general anesthesia via blinded nasotracheal intubation. To prevent postoperative relapse, temporal fascia was interpositioned and sutured. Passive mouth-opening exercises were started 10 days after the surgery. Thirty-one-millimeter mouth opening was reached after the surgery and passive mouth-opening exercises. Patient's routine controls have been continued for 2 years.

Chronic mycobacterium infections are major causes of disease burden of 20% in a tropical country like India. The inflammatory cascade following these bacterial infections often leads to tissue damage and perpetuates nec-rosis,fibrosis and the disease process.Pulmonary tuberculosis,multi-drug resistant tuberculosis not only af-fects individuals but society at large.Current remedial measures using various technology platforms singularly did not produce effective and appreciable reduction in global disease burden.On the contrary,the conventional chemotherapeutic chemical moieties have demonstrated variable pharmacogenomic expression,increased drug resistance,non compliance of strict prolonged drug regimens with debilitating side effects and contraindica-tions.Furthermore,secreted inflammatory cytokines results in chronic infection,immune deviation,and im-munopathology in the lungs.Hence,identification of immune escape mechanisms leading to chronic mycobac-terial infections is crucial for development of new treatments.The review would dwell into the basic pathogenic mechanism and the newer approaches that may need to be considered for developing novel therapeutic strate-gies.

Lateral contracture of the neck is a rare and insufficiently researched burn consequent. Contracture restricts head motion, can cause a secondary face deformity, presents severe cosmetic defects, and, therefore, requires surgical reconstruction. Literature does not sufficiently address the issue; therefore, anatomy not researched and treatment techniques not developed. The anatomy of postburn lateral cervical flexion contracture was studied in 21 operated patients. Using obtained data, new approaches were investigated, which were directed toward maximal efficacy of the local tissues use. Follow-up results were observed from 6 months to 9 years. Lateral cervical contractures were divided into two types based on their anatomy: edge and medial. Edge contractures were caused by burns and scars located on the posterior neck surface and were characterized by the presence of the fold in central lateral zone. In the fold, only one (posterior) sheet is scars that cause the contracture. Medial contractures were caused by scars located on the lateral cervical surface and were characterized by the presence of the fold in which both sheets were scars. In both types, contracture was caused by scar sheet surface deficiency in length, which has a trapezoid form (contracture cause). In all cases, there was surface surplus in the fold's sheets allowed contracture release with local tissue. The technique that allows the maximum local tissue use and ensures full contracture elimination is the trapeze-flap plasty. Two anatomic types of lateral cervical scar contractures were identified: edge and medial. An anatomically justified efficacy reconstructive technique for both types is trapeze-flap plasty.

In the last few years, several phase III clinical trials of new drug treatments for deep vein thrombosis (DVT) have been carried out or are about to finish. These drugs have a predictable and reliable pharmacokinetic and pharmacodynamic response and do not require monitoring and are consequently an attractive alternative for the treatment of a high proportion of patients with DVT. Dabigatran, edoxaban and idrabiotaparinux have been developed as an alternative to warfarin, and apixaban and rivaroxaban as one-drug only treatment for this disease, with a 1- or 3-week intensified phase of initial treatment, respectively. So far, the reported results show non-inferior efficacy and safety to warfarin or to conventional treatment. Therefore, the new anticoagulants will be particularly useful in patients with unstable INRs, warfarin incompatible pharmacologic interactions, and in those without access to regular coagulation monitoring.

Clinical assessment of a child with Tourette's syndrome (TS) includes a careful review of motor and phonic tics. In addition, commonly associated problems of such as obsessive-compulsive symptoms, or symptoms of attention deficit hyperactivity disorder (inattention, impulsiveness, and overactivity) should also be evaluated. Treatment almost always includes education of the child, family, and school personnel concerning the natural history and behavioral boundaries of the disorder. Other treatment interventions depend to a great extent on the primary source of impairment. This article, the second of two parts, presents three illustrative cases and reviews current treatment interventions for children and adolescents with TS.

Currently, there is no cure and no preventive vaccine for HIV/AIDS. Combination antiretroviral therapy has dramatically improved treatment, but it has to be taken for a lifetime, has major side effects and is ineffective in patients in whom the virus develops resistance. Nanotechnology is an emerging multidisciplinary field that is revolutionizing medicine in the 21st century. It has a vast potential to radically advance the treatment and prevention of HIV/AIDS. In this review, we discuss the challenges with the current treatment of the disease and shed light on the remarkable potential of nanotechnology to provide more effective treatment and prevention for HIV/AIDS by advancing antiretroviral therapy, gene therapy, immunotherapy, vaccinology and microbicides.

Background and Objectives: Cellulite is a biological caused modification of the female connective tissue. In extracorporeal shockwave therapy (ESWT) pulses are penetrating into the tissue without causing a thermal effect or micro lesions, but leading to a stimulation of tissue metabolism and blood circulation, inducing a natural repair process with cell activation and stem cells proliferation. Recently ESWT treatment showed evidence of remodelling collagen within the dermis and of stimulating microcirculation in fatty tissue. Study Design and Methods: The study was designed to assess acoustic wave treatment for cellulite by comparison treated vs. untreated side (upper-leg and buttock). Each individual served as its own control. 11 females with a BMI less then 30 and an age over 18 years were included. 6 treatments were given weekly with radial acoustic waves. Documentation was done before and 1, 4, 12 weeks after last treatment by standardized photo documentation, relaxed and with muscle contraction, measurement of body weight and circumference of the thigh, pinch test, and evaluation of hormonal status and lifestyle. The efficacy of AWT/EPAT was evaluated before and 1, 4, 12 weeks after last treatment. Patients rated the improvement of cellulite, overall satisfaction and acceptance. The therapist assessed improvement of cellulite, side effects and photo documentation treated vs. untreated side, before vs. after treatment. The blinded investigator evaluated the results using photo documentation right vs. left leg, before vs. after treatment in a frontal, lateral and dorsal view, relaxed and with muscle contraction. Results: The improvement of cellulite at the treated side was rated by patients with 27,3% at week 4 and 12, by the therapist with 34,1% at week 4 and 31,2% at week 12 after the last treatment The blinded investigator could verify an improvement of cellulite in an increasing number of patients with increasing time interval after treatment.

As a result of advances in experimental therapeutics, many promising therapies for PD are emerging. Levodopa remains the most potent drug for controlling PD symptoms, yet is associated with significant complications such as the “wearing off” effect, levodopa-induced dyskinesias and other motor complications. Catechol-o-methyl-transferase inhibitors, dopamine agonists and nondopaminergic therapy are alternative modalities in the management of PD and may be used concomitantly with levodopa or one another. The neurosurgical treatment, focusing on deep brain stimulation, is reviewed briefly. Although this review has attempted to highlight the most recent advances in the treatment of PD, it is important to note that new treatments are not necessarily better than the established conventional therapy and that the treatment options must be individualized and tailored to the needs of each individual patient.Keywords: Parkinson’s disease, levodopa, medical treatment, pallidotomy, deep brain stimulation

The transseptal approach is the most logical and adequate technique to reach the sella turcica and adjacent structures. In the era before the use of antibiotic and steroid replacement therapy, Harvey Cushing, MD, and Norman Dott, MD, obtained successful results by using the transseptal approach to resect and decompress pituitary adenomas. Some authors use the maxilla-premaxilla technique followed by a sublabial incision through which they introduce the trans-sphenoidal speculum. The endonasal approach is a modification of the sublabial incision, but much of the perpendicular plate of the ethmoid is still removed. Therefore, we have added another modification that consists in removing only a fragment of the perpendicular plate of the ethmoid and vomer anterior to the sphenoid rostrum. We also describe our experience with this technique and analyze our results.
Full Text Available Tic disorders are relatively common disorders of childhood. The tics range from mild to severe and show a fluctuating course over time. Moreover, in most cases, the tics tend to decline in number and frequency by early adulthood. Given this range of severity and natural history, tics may not require treatment. When tics are frequent, forceful and cause interference in everyday life, medication is indicated. Several medications have been used in the treatment of tics, but only a few have been carefully studied. This paper reviews the range of medications that have been used in the treatment of tics and provides practical information about clinical management of children and adolescents with tic disorders.
The process of group therapy with five aggressive young boys, utilizing bibliotherapy as its primary mode of intervention, was investigated and is illustrated in this paper. The rationale for using affective bibliotherapy in a group context is given, the content of the program is described, and the process is fully displayed. The effectiveness of the treatment was studied in a single-subject design, comparing treatment children with their matched counterparts. Results pointed to reduced aggression of all the five treatment students, compared with no change in the control children, by self- and teacher report. In addition, results based on an analysis of transcripts showed increased constructive behavior in group for all participants. Although these results should not be generalized, they suggest an interesting line of research for future investigation.

Muskuloskeletal ultrasound and dual-energy-CT (DECT) findings are increasingly relevant for the establishment of the diagnosis of gout, and are therefore incorporated into the novel ACR / EULAR classification criteria. Canakinumab, a monoclonal antibody directed against interleukin-1β (IL-1β) has been approved in 2013 for the treatment of acute gout and for prophylaxis of flares. In patients demonstrating an inadequate response upon treatment with allopurinol or febuxostat, combination therapy with lesinurad might reduce uric acid levels to the target of gout). Rapid lowering of uric acid levels and effective tophi reduction can be achieved with pegloticase, which can be utilized in selected patients presenting contraindications to xanthine oxidase inhibitors and uricosuric drugs. This article summarizes current scientific aspects of diagnosis, treatment and comorbidities of gout in the context of clinical relevance. © Georg Thieme Verlag KG Stuttgart · New York.

Full Text Available Objective: To introduce a new minimally invasive surgical approach to anterior and lateral craniocervical junction diseases, preserving the midline posterior cervical spine stabilizing elements and reducing the inherent morbidity risk associated with traditional approaches. Methods: We describe a novel surgical technique in four cases of extra-medullary anterolateral compressive lesions located in the occipito-cervical junction, including infections and intra- and/or extradural tumor lesions. We used a paramedian trasmuscular approach through an anatomical muscle corridor using a micro MaXcess(r surgical expandable retractor, with the purpose of reducing morbidity and preserving the posterior muscle and ligamentous tension band. Results: This type of surgical approach provides adequate visualization and microsurgical resection of lesions and reduces muscle manipulation and devascularisation, preserving the tension of the ligament complex. There was minimal blood loss and a decrease in postoperative pain, with rapid start of rehabilitation and shorter hospitalization times. There were no intraoperative complications, and all patients recovered from their pre-operative symptoms. Conclusions: This novel surgical technique is feasible and adequate for the occipito-atlanto-axial complex, with better results than traditional procedures.

Full Text Available INTRODUCTION: Dentinogenesis imperfecta (DI is a hereditary dentin development disorder that affects both primary and permanent dentitions. The DI characteristics are discolored and translucent teeth ranging from gray to brownish-blue or amber. The enamel may split readily from the dentin when subjected to occlusal stress. Radiographically there are evident of cervical constrictions, short root and pulp chambers, and the root canals are smaller than normal or completely obliterated. The dental treatment choice can be decided on a case-by case‑basis, considering the degree of dental tissue loss, and child age and cooperation. OBJECTIVE: The aim of this case report was to describe the early dental treatment performed in a child affected by DI type II. CASE REPORT: The treatment involved basic preventive procedures. Primary molars were worn to such an extent that the remained tooth structure was covered with composite resin to protect the exposed dentin. Resin-based sealant was applied in all first permanent molars. Posterior cross bite was treated with the expansion of the upper arch. CONCLUSION: The early treatment restored the patient´s vertical dimension resulting in acceptable esthetics and function for the permanent teeth to complete their eruption.

Understanding factors that contribute to eating disorders, which affect 13% of females, is critical to developing effective prevention and treatment programs. In this paper, we summarize results from prospective studies that identified factors predicting onset and persistence of eating disorders and core symptom dimensions. Next, implications for intervention targets for prevention, and treatment interventions from the risk- and maintenance-factor findings are discussed. Third, given that evidence suggests eating disorders are highly heritable, implying biological risk and maintenance factors for eating disorders, we offer working hypotheses about biological factors that might contribute to eating disorders, based on extant risk factor findings, theory, and cross-sectional studies. Finally, potentially fruitful directions for future research are presented. We suggest that it would be useful for experimental therapeutics trials to evaluate the effects of reducing the risk factors on future onset of eating pathology and on reducing maintenance factors on the risk for persistence of eating pathology, and encourage researchers to utilize prospective high-risk studies so that knowledge regarding potential intervention targets for prevention and treatment interventions for eating disorders can be advanced. Using the most rigorous research designs should help improve the efficacy of prevention and treatment interventions for eating disorders.

Pica is a very serious problem in which an individual ingests substances without nutrition value, such as paper and paint. As this behavior is often life-threatening resulting in surgery, pica has received attention from researchers for several decades. During that time, a number of interventions have been devised, such as behavioral methods (e.g., aversive stimuli, overcorrection, time-out, reinforcement) and biological interventions (e.g., pharmacotherapy, nutritional supplements). This paper is a broad review of the research on treatment studies for this problem, with a focus on persons with autism and/or intellectual disability (ID), which constitutes almost all of the published treatment papers. In addition, strengths and weaknesses of different pica treatments are discussed. Upon review, applied behavior analysis (ABA) was found to have the most robust empirical support to treat this behavior. Most clinicians are drifting away from aversive techniques and relying on more positive procedures to guide their treatment plans. The implications of current status and future directions for research are also addressed.

Improvement of patient survival by anti-angiogenic therapy has proven limited. A vaccination approach inducing an immune response against the tumor vasculature combines the benefits of immunotherapy and anti-angiogenesis, and may overcome the limitations of current anti-angiogenic drugs. Strategies to use whole endothelial cell vaccines and DNA- or protein vaccines against key players in the VEGF signaling axis, as well as specific markers of tumor endothelial cells, have been tested in preclinical studies. Current clinical trials are now testing the promise of this specific anti-cancer vaccination approach. This review will highlight the state-of-the-art in this exciting field of cancer research.

Full Text Available Abstract Objective: To compare the results of aortic valve replacement with access by sternotomy or minimally invasive approach. Methods: Retrospective analysis of medical records of 37 patients undergoing aortic valve replacement by sternotomy or minimally invasive approach, with emphasis on the comparison of time of cardiopulmonary bypass and aortic clamping, volume of surgical bleeding, time of mechanical ventilation, need for blood transfusion, incidence of atrial fibrillation, length of stay in intensive care unit, time of hospital discharge, short-term mortality and presence of surgical wound infection. Results: Sternotomy was used in 22 patients and minimally invasive surgery in 15 patients. The minimally invasive approach had significantly higher time values of cardiopulmonary bypass (114.3±23.9 versus 86.7±19.8min.; P=0.003, aortic clamping (87.4±19.2 versus 61.4±12.9 min.; P<0.001 and mechanical ventilation (287.3±138.9 versus 153.9±118.6 min.; P=0.003. No difference was found in outcomes surgical bleeding volume, need for blood transfusion, incidence of atrial fibrillation, length of stay in intensive care unit and time of hospital discharge. No cases of short-term mortality or surgical wound infection were documented. Conclusion: The less invasive approach presented with longer times of cardiopulmonary bypass, aortic clamping and mechanical ventilation than sternotomy, however without prejudice to the length of stay in intensive care unit, time of hospital discharge and morbidity.

On the basis of strong evidence, although primary monosymptomatic nocturnal enuresis (PMNE) is common and most children will outgrow the condition spontaneously, the psychological effect to the child can be significant and represents the main reason for treatment of these children. On the basis of international consensus panels, treatment of PMNE should be targeted toward the specific type of bedwetting patterns the child has, using bladder diary, sleep history, and daytime elimination concerns as a guide (Table 3). On the basis of international consensus panels, it is important for the primary care physician to be able to differentiate children with PMNE from children with nonmonosymptomatic nocturnal enuresis (NMNE) and secondary nocturnal enuresis. On the basis of international consensus panels, children with NMNE should have their underlying voiding or stool problem addressed before initiation of therapy for the nocturnal enuresis. On the basis of strong evidence, both the bedwetting alarm and desmopressin are considered first-line therapy for children with PMNE.
Full Text Available Diabetes Mellitus is a public health problem worldwide. The most effective anti-diabetic drugs currently available include insulin and newer insulin preparations, sulphonylureas, biguanides, meglitinides, thiazolidinediones, alpha- glucosidase inhibitors, incretins, guargum and glucomannan. However, the future therapies will need to focus on those patents who do not respond well to these treatments and who account for 50% of the health care costs of diabetes mellitus. Drug development for diabetes mellitus has been directed at improving currently available drugs and findings new compounds. In this review article, we will review the role of future new chemical entities able to target the metabolic disorder. Some of these new anti-diabetic treatment strategies may in the future not only control symptoms and modify the natural course of diabetes, but also potentially prevent or cure the disease.

Tuberculosis (TB) is highly infectious disease causing morbidity and death. Its causative organism is a contagious bacterium, Mycobacterium tuberculosis. The incidence of tuberculosis is increasing worldwide due to the emergence of drug resistance bacteria. The resistance is being developed in Mycobacterium tuberculosis against both the first line as well as the second line drugs used for the treatment. The tuberculosis control programme is being complicated and failed to get the desired impact due to the development of multi-drug resistant (MDR) and extensively-drug resistant (XDR) strains of Mycobacterium tuberculosis. So, there is a critical requirement to discover and produce newer anti-TB drugs with unique drug targets. Medicinal plants have been used for curing the diseases from ancient time. Medicinal plants are the novel sources for the production of alternate medicines for the treatment of TB caused by MDR and XDR strains. Plants produce a number of different kinds of secondary metabolites such as Alkaloids, Coumarins, Flavonoids, Polyphenols, Terpenoids, Quinines, etc. which have antimicrobial activity; thus may be useful in control of tuberculosis. These compounds do not contribute directly in growth and development but used by the plants for their defense. On the basis of various sources in the literature, about 72 phytochemicals constituents responsible for anti tubercular activity isolated from different plants have been explained along with their structure. Most effective isolated compounds from plants are plumbagin, maritinone, 3, 3'-biplumbagin, aloe emodin, epigallocatechin and umckalin. These phytochemicals are helpful for the treatment of MDR, XDR type of tuberculosis. This review describes an overview of the current synthetic medicines used for treatment of TB and the work carried out on anti tubercular plants along with their phytochemicals.

Full Text Available The refractory arterial hypertension (HT is diagnosed, if therapy with three antihypertensive drugs from different classes (including a diuretic in optimal doses did not provide target blood pressure (BP level. Prevalence of a refractory HT is high and reaches up 10-30% among hypertensive patients. However, poor BP control is often caused by patient non-compliance with the medical recommendations, an inadequate estimation of BP level, and "white coat" HT. It is classified as a pseudo resistance. Obesity, salt and alcohol overconsumption, taking some drugs worsen BP control. Secondary HT causes (sleep apnea syndrome, kidney diseases, renal artery stenosis, and primary hyperaldosteronism are more possible in patients with refractory HT. Specific treatment of these diseases improves BP control and long-term prognosis. Successful treatment of refractory HT includes detection and correction of reversible risk factors and reasons of the secondary HT, use of the effective combined therapy with the aldosterone antagonist. Improvement of patient compliance is one of key factors of effective treatment.
Full Text Available Cancer patients undergoing chemotherapy treatment are advised to increase food intake to overcome the therapy-induced side effects, and weight loss. Dietary restriction is known to slow down the aging process and hence reduce age-related diseases such as cancer. Fasting or short-term starvation is more effective than dietary restriction to prevent cancer growth since starved cells switch off signals for growth and reproduction and enter a protective mode, while cancer cells, being mutated, are not sensitized by any external growth signals and are not protected against any stress. This phenomenon is known as differential stress resistance (DSR. Nutrient signaling pathways involving growth hormone/insulin-like growth factor-1 axis and its downstream effectors, play a key role in DSR in response to starvation controlling the other cell maintenance systems, such as autophagy and apoptosis, that are related to the tumorigenesis. Yeast cells lacking these effectors are better protected against oxidative stress compared to normal cells. In the same way, starvation protects many cell lines and mice against high-dose chemotherapeutic drugs. According to a series of studies, fasting results in overall reduction in chemotherapy side effects in cancer patients. Data shows that starvation-dependent differential chemotherapy is safe, feasible and effective in cancer treatment, but the possible side effects of starvation limit its efficacy. However, further studies and clinical trials may result in its implementation in cancer treatment.

Acanthamoeba keratitis is a corneal disease associated predominantly with contact lens wear. The occurrence of Acanthamoeba keratitis has been rising since 1990 in correlation to the growing number of contact lens wearers. To date approximately 2000 cases have been published around the world. Due to the complicated diagnostics, the elaborate treatment and the usually bad compliance of the patients, Acanthamoeba keratitis unfortunately very often takes a serious progression, which may lead to serious visual loss and perforating keratoplasty. Today, local treatment with a combination of polyhexamethylene biguanide (PHMB) and propamidine isethionate (Brolene) is considered the first line therapy for Acanthamoeba keratitis. Alternatively also a combination of propamidine and chlorhexidine or neomycine achieves good therapeutic results. However, the complicated mode of application consistently remains a problem. The intensive local treatment, i.e. hourly application of therapeutics during the first three days day and night makes hospitalization inevitable. Moreover, sufficient efficacy can not always be achieved, and also resistance against propamidine has already been observed. Recently propamidine has sometimes been replaced by hexamidine, which seems to have a greater cysticidal activity. A new path might be struck by the application of alkylphosphocholines. These are phosphocholines esterified to aliphatic alcohols. They exhibit in vitro and in vivo antineoplastic activity and have been shown to be cytotoxic against Leishmania donovani, Trypanosoma cruzi, and Entamoeba histolytica. A recent study has demonstrated that particularly hexadecylphosphocholine is highly effective also against various strains of Acanthamoeba.

Advances in drug formulation, inhalation device design and disease management are generating new opportunities for patients suffering from obstructive pulmonary diseases. This article provides a comprehensive review of the different promising pulmonary drug delivery technologies in the treatment of obstructive pulmonary diseases, particularly with regard to the treatment of asthma and chronic pulmonary diseases (COPD), which are increasing day by day due to increasing environmental pollution and its harmful and toxic contaminants. In the recent years, a better knowledge has been gained regarding the mechanism of action of glucocorticoids and how they suppress the chronic inflammation. New etiology has been brought into light regarding the inactivity of glucocorticoids in some patients having asthma and COPDs even though the inflammatory genes are triggered by similar molecules in both the diseases. This new knowledge has given a new platform to improve glucocorticoids and their resistance also how other combination therapy can be used for these diseases. It has also led to the quest for improving and developing other alternatives such as anti-leukotriene agents, muscarinic inhibitors, combination therapy, as well as biologic immune-modulators in the treatment of the different pulmonary diseases. Several new combinations of glucocorticoids are available in the global market for the use in pulmonary diseases especially asthma although their availability fluctuates between continents. There has been several studies done regarding the variation of effectiveness of the different inhaled glucocorticoids and hence it is important to take into consideration the different delivery systems and the methods which are used to treat the patients.

SAPHO syndrome (synovitis, acne, pustulosis, hyperostosis, and osteitis) is a rare autoimmune disease which, due to its clinical presentation and symptoms, is often misdiagnosed and unrecognized. Its main features are prominent inflammatory cutaneous and articular manifestations. Treatments with immunosuppressive drugs have been used for the management of SAPHO with variable results. To date, the use of anti-TNF-α agents has proved to be an effective alternative to conventional treatment for unresponsive or refractory SAPHO cases. TNF-α is a pro-inflammatory cytokine and pivotal regulator of other cytokines, including IL-1 β, IL-6, and IL-8, involved in inflammation, acute-phase response induction, and chemotaxis. IL-1 inhibition strategies with anakinra have shown efficacy as first and second lines of treatment. In this review, we will describe the main characteristics of biological drugs currently used for SAPHO syndrome. We also describe some of the promising therapeutic effects of ustekinumab, an antibody against the p40 subunit of IL-12 and IL-23, after failure of multiple drugs including anti-TNF-α and anakinra. We discuss the use and impact of the new anti-IL-1 antagonists involved in the IL-17 blockade, in particular for the most difficult-to-treat SAPHO cases.
Full Text Available Lack of access to empirically-supported psychological treatments (EPT that are contextually appropriate and feasible to deliver by non-specialist health workers (referred to as 'counsellors' are major barrier for the treatment of mental health problems in resource poor countries. To address this barrier, the 'Program for Effective Mental Health Interventions in Under-resourced Health Systems' (PREMIUM designed a method for the development of EPT for severe depression and harmful drinking. This was implemented over three years in India. This study assessed the relative usefulness and costs of the five 'steps' (Systematic reviews, In-depth interviews, Key informant surveys, Workshops with international experts, and Workshops with local experts in the first phase of identifying the strategies and theoretical model of the treatment and two 'steps' (Case series with specialists, and Case series and pilot trial with counsellors in the second phase of enhancing the acceptability and feasibility of its delivery by counsellors in PREMIUM with the aim of arriving at a parsimonious set of steps for future investigators to use for developing scalable EPT.The study used two sources of data: the usefulness ratings by the investigators and the resource utilization. The usefulness of each of the seven steps was assessed through the ratings by the investigators involved in the development of each of the two EPT, viz. Healthy Activity Program for severe depression and Counselling for Alcohol Problems for harmful drinking. Quantitative responses were elicited to rate the utility (usefulness/influence, followed by open-ended questions for explaining the rankings. The resources used by PREMIUM were computed in terms of time (months and monetary costs.The theoretical core of the new treatments were consistent with those of EPT derived from global evidence, viz. Behavioural Activation and Motivational Enhancement for severe depression and harmful drinking respectively
Full Text Available Alzheimer's disease (AD, the most prevalent form of dementia worldwide, can be deemed as the next global health epidemic. The biochemistry underlying deposition of amyloid beta (A β and hyperphosphorylated tau aggregates in AD has been extensively studied. The oligomeric forms of Aβ that are derived from the normal soluble Aβ peptides are believed to be the most toxic. However, it is the fibrillar Aβ form that aggregates as amyloid plaques and cerebral amyloid angiopathy, which serve as pathological hallmarks of AD. Moreover, deposits of abnormally phosphorylated tau that form soluble toxic oligomers and then accumulate as neurofibrillary tangles are an essential part of AD pathology. Currently, many strategies are being tested that either inhibit, eradicate or prevent the development of plaques in AD. An exciting new approach on the horizon is the immunization approach. Dramatic results from AD animal models have shown promise for active and passive immune therapies targeting A β. However, there is very limited data in humans that suggests a clear benefit. Some hurdles faced with these studies arise from complications noted with therapy. Encephalitis has been reported in trials of active immunization and vasogenic edema or amyloid-related imaging abnormalities (ARIA has been reported with passive immunization in a minority of patients. As yet, therapies targeting only tau are still limited to mouse models with few studies targeting both pathologies. As the majority of approaches tried so far are based on targeting a self-protein, though in an abnormal conformation, benefits of therapy need to be balanced against the possible risks of stimulating excessive toxic inflammation. For better efficacy, future strategies will need to focus on the toxic oligomers and targeting all aspects of AD pathology. doi: 10.3969/j.issn.1672-6731.2014.03.001

Transsphenoidal surgery in the setting of acromegaly is quite challenging due to increased soft tissue mass, bony overgrowth, and bleeding. There is a debate on the endoscopic versus microscopic approach for these patients. The purpose of our study is to compare the outcomes for acromegaly after transsphenoidal surgery using both techniques. Retrospective review of 65 acromegalic patients who underwent transsphenoidal surgery in our department. Clinical remission was defined as resolution of typical acromegalic symptoms. Radiological resection was defined by volumetric criteria, and biochemical remission was defined as by the 2010 consensus on the criteria for remission of acromegaly. There was no significant difference in age, preoperative endocrine status, percent of macro adenomas, suprasellar, or infrasellar extension between both groups. Patients were assigned to both groups based on our existing referral pattern. Endoscopic approach was performed in 42 patients, while the microscopic approach was performed in 23 patients. No significant difference in remission rates was found between both groups (45.2 vs. 34.7 %, p = 0.40). The endoscopic group, however, had a significantly higher rate of gross total resections (61 vs. 42 %, p = 0.05). There was also a trend towards higher rates of gross total resections when cavernous sinus was present (48 vs. 14.2 %, p = 0.09). Postoperative diabetes insipidus occurred more in microscopic patients (34.7 vs. 17 %, p = 0.05), otherwise there was no significant difference in rates of complications. The median follow-up period was 56.6 months (range 6-156, mean 66.1). There is no significant difference in the rates of biochemical remission between the endoscopic and microscopic techniques. The endoscope technique, however, seems to be superior in achieving gross total resection especially with tumors invading the cavernous sinus.

Full Text Available The study aimed a comparison of treatment results in patients with two-column acetabular fractures (AO, Type C when using different operative approaches: ilioinguinal (12, Y-type (16 and a combination of posterior-lateral and ilioinguinal approaches (3. Surgical treatment was carried out not later than 3 weeks after injury. The joint congruence was reached in all the cases. The operative time, blood loss, complications, long-term results of treatment were evaluated. The study showed the effectiveness of ilioinguinal approach in case of the simple two-column fractures. When treating patients with complex fractures of the anterior column, the authors found no significant difference in operative time and intraoperative blood loss between the cases of V-type and combined approaches. In patients with two-column fractures accompanied with posterior wall lesion the time of surgery was significantly lower when using the Y-shaped approach as against the two different approaches.

Acute metabolic acidosis is associated with increased morbidity and mortality because of its depressive effects on cardiovascular function, facilitation of cardiac arrhythmias, stimulation of inflammation, suppression of the immune response, and other adverse effects. Appropriate evaluation of acute metabolic acidosis includes assessment of acid-base parameters, including pH, partial pressure of CO(2) and HCO(3)(-) concentration in arterial blood in stable patients, and also in central venous blood in patients with impaired tissue perfusion. Calculation of the serum anion gap and the change from baseline enables the physician to detect organic acidoses, a common cause of severe metabolic acidosis, and aids therapeutic decisions. A fall in extracellular and intracellular pH can affect cellular function via different mechanisms and treatment should be directed at improving both parameters. In addition to supportive measures, treatment has included administration of base, primarily in the form of sodium bicarbonate. However, in clinical studies of lactic acidosis and ketoacidosis, bicarbonate administration has not reduced morbidity or mortality, or improved cellular function. Potential explanations for this failure include exacerbation of intracellular acidosis, reduction in ionized Ca(2+), and production of hyperosmolality. Administration of tris(hydroxymethyl)aminomethane (THAM) improves acidosis without producing intracellular acidosis and its value as a form of base is worth further investigation. Selective sodium-hydrogen exchanger 1 (NHE1) inhibitors have been shown to improve haemodynamics and reduce mortality in animal studies of acute lactic acidosis and should also be examined further. Given the important effects of acute metabolic acidosis on clinical outcomes, more intensive study of the pathogenesis of the associated cellular dysfunction and novel methods of treatment is indicated.
There are many guidelines available concerning the treatment of Parkinson's disease. Most of these advocate treating young-onset patients with a dopamine agonist and older patients with levodopa. The rationale behind this recommendation has its origins in the side effects associated with each of these drug classes: whilst levodopa leads to dyskinesia, which may not be relevant for patients with a limited life-expectancy, dopamine agonists have a much longer plasma half life which probably leads to more continuous dopamine receptor stimulation and thus decreases the occurrence and severity of dyskinesia. However, the side effects associated with the use of dopamine agonists, such as sleepiness, orthostatic problems, hallucinations and impulse control disorders are a drawback. In this overview, the hypothesis will be put forward that perhaps such a strict distinction is no longer needed. A new idea may be the early combination of levodopa with a dopamine agonist which would provide good clinical efficacy and, because of the relatively low doses involved, would reduce the side effects associated with both substances. MAO-B inhibitors may be a good option for early treatment and especially for patients who experience first motor fluctuations. Similarly, and particularly if a wearing-off symptom is present, COMT inhibitors smoothen and prolong the action of levodopa. More invasive escalation therapy comes into play when patients reach the advanced stages with problems of insufficient motor control, such as bradykinesia, rigidity and resting tremor, combined with on-time dyskinesia. The use of all oral and invasive treatment has to be individualized to gain a good motor and non-motor control and especially a good quality of life.

Amelogenesis imperfecta is a set of hereditary defects representing mainly the development defects of enamel without the presence of whole-body symptoms. Developmental disorders can manifest a complete absence of enamel, which is caused by improper differentiation of ameloblasts. This article describes the diagnosis and treatment of a patient with amelogenesis imperfecta, as well as the need for interdisciplinary cooperation to achieve the best possible morphological, skeletal, functional and aesthetic rehabilitation of the patients with this diagnosis. Furthermore, the article reviews literature dealing with other anomalies occurring in association with amelogenesis imperfect (Fig. 12, Ref. 20).

Malignant gliomas, which include glioblastomas and anaplastic astrocytomas, are the most common primary tumors of the brain. Over the past 30 years, the standard treatment for these tumors has evolved to include maximal safe surgical resection, radiation therapy and temozolomide chemotherapy. While the median survival of patients with glioblastomas has improved from 6 months to 14.6 months, these tumors continue to be lethal for the vast majority of patients. There has, however, been recent substantial progress in our mechanistic understanding of tumor development and growth. The translation of these genetic, epigenetic and biochemical findings into therapies that have been tested in clinical trials is the subject of this review.

Amyloidotic cardiomyopathy (ACMP) occurs in the setting of rare genetic diseases, blood dyscrasias, chronic infection and inflammation, and advanced age. Cardiologists are on the front lines of diagnosis of ACMP when evaluating patients with unexplained dyspnea, congestive heart failure, or arrhythmias. Noninvasive detection of diastolic cardiac dysfunction and unexplained left ventricular hypertrophy should be followed by biopsy to demonstrate the presence of amyloid deposits and appropriate genetic, biochemical, and immunologic testing to accurately define the type of amyloid. Growing numbers of treatment options exist for these diseases, and timely diagnosis and institution of therapy is essential for preservation of cardiac function.

Waste water is a major environmental impediment for the growth of the textile industry besides the other minor issues like solid waste and resource waste management. Textile industry uses many kinds of synthetic dyes and discharge large amounts of highly colored wastewater as the uptake of these dyes by fabrics is very poor. This highly colored textile wastewater severely affects photosynthetic function in plant. It also has an impact on aquatic life due to low light penetration and oxygen consumption. It may also be lethal to certain forms of marine life due to the occurrence of component metals and chlorine present in the synthetic dyes. So, this textile wastewater must be treated before their discharge. In this article, different treatment methods to treat the textile wastewater have been presented along with cost per unit volume of treated water. Treatment methods discussed in this paper involve oxidation methods (cavitation, photocatalytic oxidation, ozone, H2O2, fentons process), physical methods (adsorption and filtration), biological methods (fungi, algae, bacteria, microbial fuel cell). This review article will also recommend the possible remedial measures to treat different types of effluent generated from each textile operation.

Schizophrenia is a serious mental disorder with a challenging rational pharmacotherapy. Neurochemical transmission in the dopaminergic system, especially via D2 receptors, and related changes in postsynaptic signal transduction are very important in both the formation of schizophrenia and current pharmacotherapeutic treatment with antipsychotic drugs. Blocking the serotonergic 5-HT2A and 5-HT2C receptors is growing growing importance with regard to the action mechanisms of new generation antipsychotic medications. Recent preclinical and clinical data show that dysfunction of central neurotrophins, such as nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), and neurophin-3 (NT-3) might contribute to impaired brain development and neuroplasticity, leading to schizophrenia. In addition, some recent studies suggest that there is an important relationship between alcohol and substance addiction, and schizophrenia. There is also some preclinical data indicating that the central nitrergic system and agmatine(3/4)a biologically active agent produced after decarboxylation of arginine(3/4)might be interesting and important targets for understanding the etiopathogenesis of schizophrenia and for development of new drugs. Selective dopamine D3 receptor antagonists, specific agonists for metabotropic and NMDA receptors of the glutamatergic system, and nicotinic alpha-7 receptor agonists were reported in preclinical and a limited number of clinical studies as potential new targets for schizophrenia treatment. In this review, new advances in the pharmacotherapy of schizophrenia and possible new targets are discussed in the light of the current literature.
Full Text Available Retroperitoneal fibrosis (RPF is a rare disease of unclear etiology, which is characterized by a chronic non specific inflammation of the retroperitoneum. This inflammation of the retroperitoneum may entrap and obstruct retroperitoneal structures, particularly the ureters. Patients with RPF show non specific clinical symptoms, including poorly localized back pain, general malaise, weight loss, anemia, features of renal failure and occasionally, mild fever. The early symptoms are non specific and an accurate diagnosis is often achieved only subsequent to urological obstruction or the occurrence of renal failure. Although a number of scientific journals devoted to RPF are present in the litera¬ture, there is no accepted diagnostic or therapeutic strategy for this disease. However, there are several therapeutic strate¬gies which have been proven to be effective. Hereby, we reported two cases of retroperitoneal fibrosis which had similar symptoms and findings but different responses to medical treatment .We aimed to discuss challanges of RPF%u2019s diagnosis and the treatment protocol.

Hypertension is the most common medical disorder encountered during pregnancy, occurring in about 6-8 % of pregnancies. Preeclampsia is a pregnancy-specific disorder that occurs after 20 weeks' gestation, characterized by hypertension and proteinuria. Preeclampsia can also occur superimposed upon chronic hypertension. Eclampsia is the convulsive form of preeclampsia, and affects 0.1 % of all pregnancies. In low-income and middle-income countries, preeclampsia and eclampsia are associated with 10-15 % of direct maternal deaths. Women who develop preeclampsia in pregnancy are at greater risk of cardiovascular and cerebrovascular events even years after their pregnancies. There is significant progress in the elucidation of the underlying mechanisms and pathophysiology of preeclampsia, although its therapeutics remains challenging; delivery of the fetus is still the definitive treatment. Different international societies have produced recommendations and guidelines for clinicians treating preeclampsia, with an overall goal of improving maternal and fetal outcomes. In this review, we focus on the level of blood pressure at which to commence treatment and the current clinical management strategies available to treat and possibly prevent preeclampsia. We also briefly outline some newer perspectives on management of the disorder.
Full Text Available Venous ulcers (stasis ulcers, varicose ulcers are the wounds occurring due to inappropriate functioning of venous valves, usually of the legs. It is one of the most serious chronic venous insufficiency complications. The overall incidence rate is 0.76% in men and 1.42% in women. When a venous valve gets damaged, it prevents the backflow of blood, which causes pressure in the veins that leads to hypertension and, in turn, venous ulcers. These are mostly along the medial distal leg, which is often very painful, can bleed, and get infected. Treating varicose ulcers is a difficult task to the physician and a nightmare to the suffering patients, though a good number of the treatment principles are mentioned and practiced in allied sciences. In Ayurveda, this condition is considered as dus.t.a vran.a. It can be managed with the specific s′odhana therapy. So, the same treatment protocol was used to treat the case discussed here, i.e. with Nitya virecana and by Basti karma. The wound was successfully treated and, therefore, is discussed in detail.
Full Text Available Masticatory muscle pain is the second most frequent cause of orofacial pain after dental pain. Myofascial pain dysfunction syndrome (MPDS is the most common form of temporomandibular joint dysfunction. MPDS is a pain that triggers from [sensitive] points in the muscles and fascia and is followed by spasm, tenderness to palpation, restricted movement, fatigue, and sometimes dysfunction. The researchers intended to collect comprehensive information about therapeutic interventions for myofascial pain through the conduction of a critical study based on evidence in the literature. In this review, 51 English articles, published between 1981 and 2013, were extracted from PubMed, Medline, Ovid, and Google Scholar. These articles were then reviewed in detail in two categories, namely pharmaceutical and non-pharmaceutical treatments. MPDS treatment should be first focused on the identification and correction of underlying causes. Thiocolchicoside (TCC, non-steroidal anti-inflammatory drugs (NSAIDs, and Cox-2 inhibitors are among promising pharmaceutical methods. On the other hand, ultrasound and laser therapy are among promising non-pharmaceutical methods. The complex mechanism of MPDS, along with its underlying peripheral and central nervous mechanisms may make MPDS, difficult to treat, especially in its chronic form.

Parasomnias are a group of disorders characterized by abnormal behaviors, physical activities, and autonomic arousal symptoms while transition to sleep or continuation of sleep. Sleep terror (ST) is classified under parasomnias characterized by sudden fear attacks beginning with crying attacks or high-frequency screams and continuing with increased autonomic symptoms. ST occurs in the first few hours of sleep during the delta phase. Further, the lifetime prevalence of ST in adults is less than 1%. It is important to obtain; anamnesis from patients' bed partner for a clinical evaluation of ST. Methods, such as evaluating sleep diaries and video recordings, can help ST diagnosis. It is also important to evaluate patients' medical history, history of substance or alcohol abuse, psychological traumatic experiences, primary or secondary incomes, and detailed neurological aspects. Physician can select some serotonin reuptake inhibitors (SSRIs) or tricyclic antidepressants (TCADs) as medical treatment if patients have a high frequency of attacks. Because of addiction and relapse of ST episodes, benzodiazepines are not preferred as the first-line treatment. In this study, we will discuss ST, which is rare in adulthood, and use of long-acting benzodiazepine based on two cases.

Data from 33 randomized treatment studies were subjected to a meta-analysis to address questions surrounding the efficacy of psychological approaches in the treatment of specific phobia. As expected, exposure-based treatment produced large effects sizes relative to no treatment. They also outperformed placebo conditions and alternative active psychotherapeutic approaches. Treatments involving in vivo contact with the phobic target also outperformed alternative modes of exposure (e.g., imaginal exposure, virtual reality, etc.) at post-treatment but not at follow-up. Placebo treatments were significantly more effective than no treatment suggesting that specific phobia sufferers are moderately responsive to placebo interventions. Multi-session treatments marginally outperformed single-session treatments on domain-specific questionnaire measures of phobic dysfunction, and moderator analyses revealed that more sessions predicted more favorable outcomes. Contrary to expectation, effect sizes for the major comparisons of interest were not moderated by type of specific phobia. These findings provide the first quantitative summary evidence supporting the superiority of exposure-based treatments over alternative treatment approaches for those presenting with specific phobia. Recommendations for future research are also discussed.

Type 2 diabetes mellitus(T2DM)and hypertension represent two common conditions worldwide.Their frequent association with cardiovascular diseases makes management of hypertensive patients with T2DM an important clinical priority.Carvedilol and renal denervation are two promising choices to reduce plasma glucose levels and blood pressure in hypertensive patients with T2DM to reduce future complications and improve clinical outcomes and prognosis.Pathophysiological mechanisms of both options are under investigation,but one of the most accepted is an attenuation in sympathetic nervous system activity which lowers blood pressure and improves insulin sensitivity.Choice of these therapeutic approaches should be individualized based on specific characteristics of each patient.Further investigations are needed to determine when to consider their use in clinical practice.

There is an impelling need to develop effective therapeutic strategies for patients with retinal disorders. Gleaning from the large quantity of information gathered over the past two decades on the mechanisms governing degeneration of the retina, it is now possible to devise innovative therapies based on retinal gene transfer. Different gene-based approaches are under active investigation. They include strategies to correct the specific genetic defect in inherited retinal diseases, strategies to delay the onset of blindness independently of the disease-causing mutations and strategies to reactivate residual cells at late stages of the diseases. In this review, we discuss the status of application of these technologies, outlining the future therapeutic potential for many forms of retinal blinding diseases. PMID:27875674
Full Text Available Being diagnosed and treated for breast cancer is emotionally and physically challenging. Breast cancer is the most commonly diagnosed cancer and the second leading cause of death for women in the United States. Accordingly, women with a breast cancer history are the largest group of female cancer survivors. Psychological stress substantially augments adverse autonomic, endocrine, and immune discharge, including enhanced production of proinflammatory cytokines. Importantly, inflammation is a key biological mechanism underlying the symptom cluster of pain, depression, fatigue, and sleep disturbances; there is also good evidence that inflammation contributes to breast cancer recurrence. Stress may exert direct effects on psychological and physiological risk processes. In this review, we take a biobehavioral approach to understanding predictors and mechanisms underlying somatic symptoms in breast cancer survivors.
Full Text Available Adele Sparavigna, Beatrice Tenconi, Ileana De Ponti, Laura La PennaDermIng srl, Clinical Research and Bioengineering Institute, Monza, MB, ItalyAbstract: Acne is characterized by primary lesions on the face, chest, and back, and by a variety of other signs and symptoms. In particular, acne inflammatory lesions result from Propionibacterium acnes colonization and are of particular relevance as they can cause permanent scarring. Acne also causes significant psychological morbidity in affected patients. Products currently available for the treatment of acne include systemic and topical treatments. As these products can cause severe side effects, new, innovative therapies are needed. Farmaka Acne Cream (FAC is a novel, film-forming cream developed to treat mild and moderate acne. In vitro studies have demonstrated that FAC is as effective as 5% benzoyl peroxide in inhibiting growth of P. acnes. In 32 subjects with mild or moderate acne, FAC reduced all the major signs and symptoms of the disease. These included itching, erythema, and scaling, as well as reductions in the numbers of papules, pustules, and open and closed comedones. Acne severity improved in 38% of subjects, while none worsened. FAC was found to be effective in controlling sebum secretion, and was non-comedogenic. Most subjects (90% reported tolerability as good or very good, while clinical efficacy and cosmetic acceptability were judged as good. For assessment of contact sensitization and photosensitization, FAC was applied daily to the backs of 29 subjects in two symmetric areas for 10 days. Using a solar stimulator, one minimal erythema dose was delivered to one side of the back from days 11 to 13. The four different subareas of treated/untreated and irradiated/nonirradiated and combinations thereof were compared. No cases of contact sensitization or photosensitization were observed, and FAC is considered safe for use in intense sunlight. In vitro and in vivo studies provide
Full Text Available Seasonal affective disorder or SAD is a recurrent major depressive disorder with a seasonal pattern usually beginning in fall and continuing into winter months. A subsyndromal type of SAD, or S-SAD, is commonly known as “winter blues.” Less often, SAD causes depression in the spring or early summer. Symptoms center on sad mood and low energy. Those most at risk are female, are younger, live far from the equator, and have family histories of depression, bipolar disorder, or SAD. Screening instruments include the Seasonal Pattern Assessment Questionnaire (SPAQ. Typical treatment includes antidepressant medications, light therapy, Vitamin D, and counselling. This paper provides an overview of SAD.

Chronic perineal pain is the anorectal and perineal pain without underlying organic disease, anorectal or endopelvic, which has been excluded by careful physical examination, radiological and endoscopic investigations. A variety of neuromuscular disorders of the pelvic floor lead to the different pathological conditions such as anorectal incontinence, urinary incontinence and constipation of obstructed defecation, sexual dysfunction and pain syndromes. The most common functional disorders of the pelvic floor muscles, accompanied by perineal pain are levator ani syndrome, proctalgia fugax, myofascial syndrome and coccygodynia. In the diagnosis of these syndromes, contributing to a thorough history, physical examination, selected specialized investigations and the exclusion of organic disease with proctalgia is carried out. Accurate diagnosis of the syndromes helps in choosing an appropriate treatment and in avoiding unnecessary and ineffective surgical procedures, which often are performed in an attempt to alleviate the patient's symptoms.

Surgical management of tumors located in the spine and the pelvis involves greater difficulty. Moreover, these tumors are usually very large and vascularized. Preoperative embolization of the internal iliac artery is a relatively safe procedure that may reduce the risk of bleeding and local recurrence in the case of benign tumors. Chondroblastoma is a tumor that is rarely located in the pelvis; its more frequent location is the triradiate cartilage. We describe a case of a chondroblastoma with a relapsing aneurysmal cystic component in the acetabulum of an adolescent patient. Treatment consisted of embolization of the internal iliac artery, fluid hyperthermia, hydrogen peroxide and bone marrow application. The patient was found to be asymptomatic at the 5-year postoperative follow-up. The technetium (99mTc) sestamibi scan was negative for tumor activity and found no lung metastases.

We report a rare case of large bowel obstruction secondary to a gallstone impacted within the sigmoid colon, in the presence of sigmoid diverticular disease. An 89-year-old woman presented with an 8-day history of increasing abdominal distension, pain and associated nausea. Abdominal X-ray demonstrated large bowel dilation. CT scan revealed a fistula between an inflamed gallbladder and the hepatic flexure of the colon, with a large gallstone in the sigmoid colon. Proximal dilated large bowel was evident to the caecum. Flexible sigmoidoscopy was performed as the least invasive potential treatment method with a view to basket retrieval or fragmentation of the stone. Owing to poor views and risk of diverticular perforation, the procedure was abandoned, hence laparotomy was performed. Antegrade manipulation and per-rectal evacuation were attempted but failed due to a thickened, angulated sigmoid colon. Retrograde milking of the stone to the caecum and retrieval via modified appendicectomy was successful.

Gallstone ileus is a mechanical intestinal obstruction due to gallstone impaction within the gastrointestinal tract. Less than 1% of cases of intestinal obstruction are derived from this etiology. The symptoms and signs of gallstone ileus are mostly nonspecific. This entity has been observed with a higher frequency among the elderly, the majority of which have concomitant medical illness. Cardiovascular, pulmonary, and metabolic diseases should be considered as they may affect the prognosis. Surgical relief of gastrointestinal obstruction remains the mainstay of operative treatment. The current surgical procedures are: (1) simple enterolithotomy; (2) enterolithotomy, cholecystectomy and fistula closure (one-stage procedure); and (3) enterolithotomy with cholecystectomy performed later (two-stage procedure). Bowel resection is necessary in certain cases after enterolithotomy is performed. Large prospective laparoscopic and endoscopic trials are expected. PMID:26843914

Two phase III randomized studies (GOG-218 36 and ICON-7 37 have recently demonstrated the efficacy of bevacizumab (recombinant monoclonal antibody that binds with a high affinity to VEGF-A in adjunct to Cb-P, with 12-15 months maintenance treatment.Methods: the quality of evidence provided was assessed by the use of the GRADE method. Each outcome (deemed to be essential for the purpose of evaluation of the intervention was assessed to express the degree of confidence in the entity of the beneficial and/or harmful effects of the intervention. Thus, limitations in the quality of conducting the studies (risk of bias, direct applicability/relevance of results to the target population, and precision of results were taken into account.Results: the GOG-218 and the ICON7 study (high-risk subgroup demonstrated with MODERATE confidence an improvement in critical outcomes PFS and OS, with an absolute reduction of 96 (GOG-218 – 103 (ICON-7 episodes of progression, and 40 (GOG-218 – 135 (ICON-7 deaths per 1 000 patients. A marked increase in risk of hypertension of Grade ≥3 was observed, with an absolute increase of 59 episodes per 1 000 patients in the ICON-7 study, and 157 episodes in the GOG-218 study, respectively, the majority of which were controlled by means of appropriate treatment. The increased risk of other adverse events considered was negligible.Conclusions: the positive effects produced should be viewed as taking prevalence over the negative effects (FAVOURABLE benefit/harm ratio.

Stroke patients are prone to life-threatening bacterial pneumonia. Previous experimental stroke studies have demonstrated that preventive antibiotic treatment (PAT) improves outcome compared with placebo treatment, which however does not model the clinical setting properly. Here we investigate whether PAT is superior to the current clinical ‘gold standard' for treating poststroke infections. Therefore, we modeled stroke care according to the current stroke guidelines recommending early antibiotic treatment after diagnosing infections. To reliably diagnose pneumonia in living mice, we established a general health score and a magnetic resonance imaging protocol for radiologic confirmation. Compared with standard treatment after diagnosis by these methods, PAT not only abolished pneumonia successfully but also improved general medical outcome. Both, preventive and standard antibiotic treatment using enrofloxacin improved survival in a similar way compared with placebo treatment. However, in contrast to standard treatment, only PAT improved functional outcome assessed by gait analysis. In conclusion, standard and preventive treatment approach reduced poststroke mortality, however at the cost of a worse neurologic outcome compared with preventive approach. These data support the concept of PAT for treating patients at risk for poststroke infections and warrant phase III trials to prove this concept in clinical setting. PMID:23361393

In this paper, literature will be reviewed to assess the role of modern radiotherapy and radiosurgery in the management of pituitary adenomas. Material and Methods: Nowadays, magnetic resonance imaging for the definition of the target volume and a real three-dimensional (3-D) treatment planning with field conformation and the possibility for non-coplanar irradiation has to be recommended. Most groups irradiate these benign tumors with single doses of 1.8-2.0 Gy up to a total dose of 45 Gy or 50.4 Gy in extensive parasellar adenomas. Adenomas are mostly small, well circumscribed lesions, and have, therefore, attracted the use of stereotactically guided high-precision irradiation techniques which allow extreme focussing and provide steep dose gradients with selective treatment of the target and optimal protection of the surrounding brain tissue. Results: Radiation therapy controls tumor growth in 80-98% of patients with non-secreting adenomas and 67-89% for endocrine active tumors. Reviewing the recent literature including endocrine active and non-secreting adenomas, irradiated postoperatively or in case of recurrence the 5-, 10- and 15-year local control rates amount 92%, 89% and 79%. In cases of microprolactinoma primary therapy consists of dopamine agonists. Irradiation should be preferred in patients with macroprolactinomas, when drug therapy and/or surgery failed or for patients medically unsuitable for surgery. Reduction and control of prolactin secretion can be achieved in 44-70% of patients. After radiotherapy in acromegaly patients somatomedin-C and growth hormone concentrations decrease to normal levels in 70-90%, with a decrease rate of 10-30% per year. Hypercortisolism is controlled in 50-83% of adults and 80% of children with Cushing's disease, generally in less than 9 months. Hypopituitarism is the most common side effect of pituitary irradiation with an incidence of 13-56%. Long-term overall risk for brain necrosis in a total of 1,388 analyzed

Nonalcoholic fatty liver disease(NAFLD) has been identified as one of the most prevalent chronic liver disease in adults and children populations. NAFLD is usually associated with the metabolic syndrome(MS), which is chiefly related to insulin resistance and its consequences. Insulin resistance has a crucial role in the pathogenesis of hepatic steatosis and potentially nonalcoholic steatohepatitis(NASH). Because of the contemporary epidemics of MS and obesity, the burden of NAFLD is also expected to rise. Unhealthy diets, such as the so-called western diet, are enriched in fructose, trans-fatty acids and saturated fat and seem to be associated with the development of NAFLD. In human studies, certain dietary sugars, particularly fructose, are used as a substrate for lipogenesis leading to hepatic fatty infiltration, inflammation, and possibly fibrosis. Other investigations have shown that fat consumption especially cholesterol and trans/saturated fatty acids are also steatogenic and seem to increase visceral adiposity. The identification of specific dietary components that favor the development of NASH could be important for the management of this disorder. This review focuses on the effects of different dietary approaches to prevent and treat NAFLD emphasizing the macronutrients and energy composition.

Problems related to acid rock drainage (ARD) occur along many highways of British Columbia. The ARD problem at Pennask Creek along Highway 97C in the Thompson-Okanagan region is an ideal site for pilot study to investigate a possible remediation solution. The highway was opened in 1991. An ARD problem was identified in 1997. Both sides of Highway 97C are producing acidified runoff from both cut rock surface and a fractured ditch. This runoff eventually enters Pennask Creek, the largest spawning source of rainbow trout in British Columbia. The current remediation technique using limestone for ARD treatment appears to be unnecessarily expensive, to generate additional solid waste and to not be optimally effective. A soil mineral natural zeolite - clinoptilolite - which is inexpensive and locally available, has a high metal adsorption capacity and a significant buffering capacity. Moreover, the clinoptilolite materials could be back-flushed and reused on site. An earlier batch adsorption study from our laboratory demonstrated that clinoptilolite has a high adsorption capacity for Cu, Zn, Al, with adsorption concentrations 131, 158 and 215 mg/kg clinoptilolite, respectively, from ARD of pH 3.3. Removal of metals from the loaded clinoptilolite by back-flushing was found to depend on the pH, with an optimum pH range for extraction of 2.5 to 4.0 for a contact time of one hour. The rank of desorption effectiveness was EDTA > NaCl > NaNO3 > NaOAC > NaHCO3 > Na2CO3 > NaOH > Ca(OH)2. A novel process involving cyclic adsorption on clinoptilolite followed by regeneration of the sorbent by desorption is examined for the removal of heavy metals from acid rock drainage. Experimental results show that the adsorption of zinc and copper depends on the pH and on external mass transfer. Desorption is assisted by adding NaCl to the water. A slurry bubble column was able to significantly reduce the time required for both adsorption and desorption in batch tests. XRD analysis indicated

In recent years, a number of articles have been published on the treatment of acute pancreatitis in experimental models and most of them were published about animals with mild disease. However, it is difficult to translate these results into clinical practice. For example, infliximab, a monoclonal TNF antibody, was experimentally tested in rats and it was able to significantly reduce the pathologic score and serum amylase activity, and also alleviate alveolar edema and acute respiratory distress syndrome; no studies are available in clinical human acute pancreatitis. Another substance, such as interleukin 10, was efficacious in decreasing the severity and mortality of lethal pancreatitis in rats, but seems to have no effect on human severe acute pancreatitis. Thus, the main problem in acute pancreatitis, especially in the severe form of the disease, is the difficulty of planning clinical studies capable of giving hard statistically significant answers regarding the benefits of the various proposed therapeutic agents previously tested in experimental settings. According to the pathophysiology of acute pancreatitis, we may re-evaluate the efficacy of the drugs already available, such as gabexate mesilate, lexipafant and somatostatin which should be probably administered in a different manner. Of course, also in this case, we need large studies to test this hypothesis. Another great problem is prevention of the infection of pancreatic necrosis. A randomized study has been published to test the hypothesis that probiotics and specific fibres used as supplements in early enteral nutrition may be effective in reducing pancreatic sepsis and the number of surgical interventions. A study named PROPATRIA (Probiotic Prophylaxis in Patients with Predicted Severe Acute Pancreatitis) has been planned to give a more robust confirmation to the previous study. Furthermore, the open question of the prevention of the fungal infection of necrosis is still being debated. Finally, the

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia and is associated with substantial cardiovascular morbidity and mortality. The arrhythmia can be initiated and/or maintained by rapidly firing foci, single- and multiple-circuit reentry. Once initiated, AF alters atrial electrical and structural properties (atrial remodeling) in a way that promotes its own maintenance and recurrence and may alter the response to antiarrhythmic drugs. Thus, initial episodes of paroxysmal (self-terminating) AF lengthens to the point where the arrhythmia becomes persistent (requires cardioversion to restore sinus rhythm) and permanent. AF usually requires a trigger for initiation and a favorable electrophysiological and/or anatomical substrate for maintenance. The substrate includes both cardiovascular (coronary artery disease, valvular heart disease, heart failure, hypertension, dilated cardiomyopathy) and non cardiovascular diseases (thyrotoxicosis, pulmonary diseases). Accordingly, the initial step in patients with AF requires a careful assessment of symptoms and identification of underlying reversible triggers and potentially modifiable underlying structural substrate and treat them aggressively. In contrast to other cardiac arrhythmias, antiarrhythmic drugs (ADs) are the mainstay of therapy. Long-term treatment of AF is directed to restore and maintain the sinus rhythm with class I and III ADs (rhythm-control) or to allow AF to persist and ensure that the ventricular rate is controlled (rate-control) with atrioventricular nodal blocking drugs (digoxin, beta-blockers, verapamil, diltiazem) and prevent thromboembolic complications with anticoagulants. However, the long-term efficacy of ADs for preventing AF recurrence is far from ideal, because of limited efficacy (AF recurs in at least one-half of the patients) and potential side effects, particularly proarrhythmia. Thus, the choice of the appropriate AD will depend on the temporal pattern of the arrhythmia

Although unicentric Castleman disease is curable with complete surgical excision, its multicentric counterpart is a considerable therapeutic challenge. The recent development of biological agents, particularly monoclonal antibodies to interleukin-6 and its receptor, allow for more targeted disease-specific intervention that promises improved response rates and more durable disease control; however, further work is required to fill knowledge gaps in terms of underlying pathophysiology and to facilitate alternative treatment options for refractory cases.

Cardiovascular and renal diseases are associated with many risk factors, of which hypertension is one of the most prevalent. Worldwide, blood pressure control is only achieved in ∼50% of those treated for hypertension, despite the availability of a considerable number of antihypertensive drugs from different pharmacological classes. Although many reasons exist for poor blood pressure control, a likely contributor is the inability to predict to which antihypertensive drug an individual is most likely to respond. Hypertension pharmacogenomics and other 'omics' technologies have the potential to identify genetic signals that are predictive of response or adverse outcome to particular drugs, and guide selection of hypertension treatment for a given individual. Continued research in this field will enhance our understanding of how to maximally deploy the various antihypertensive drug classes to optimize blood pressure response at the individual level. This Review summarizes the available literature on the most convincing genetic signals associated with antihypertensive drug responses and adverse cardiovascular outcomes. Future research in this area will be facilitated by enhancing collaboration between research groups through consortia such as the International Consortium for Antihypertensives Pharmacogenomics Studies, with the goal of translating replicated findings into clinical implementation.
Full Text Available Pediatric nephrotic syndrome (NS is a chronic glomerular disorder, and if untreated, is associated with increased risk of life-threatening infectious, thromboembolism, lipid abnormalities, and malnutrition. The aim of the management of NS in children is to induce and maintain complete remission with resolution of proteinuria and edema without encountering serious adverse effects of therapy. Over 90% of cases in children with idiopathic NS and a majority of them will respond to steroid therapy. However, a substantial number of patients relapse frequently and become steroid dependent. The occurrence of frequent relapses necessitates clear therapeutic strategies in order to maintain sustained remission and minimize steroid toxicity. Numerous therapeutic regimens have been proposed utilizing steroid sparing agents such as alkylating agents, principally, cyclophosphamide and chlorambucil, calcineurin inhibitors namely cyclosporin A and an immunomodulatory drug, levamisole, with variable success and associated side-effects. Recently, mycophenolate mofetil (MMF, tacrolimus, the anti-CD20 antibody, rituximab, have emerged as new therapeutic options for the management of steroid dependent NS in a few uncontrolled clinical trials. It is therefore important that the benefits and risks of these agents are weighed before considering their use in the treatment of patients with NS.

Chronic metabolic acidosis is not uncommon in patients with chronic kidney disease (CKD). Clinical practice guidelines suggest that clinicians administer alkali to maintain serum bicarbonate level at a minimum of 22 mEq/L to prevent the effects of acidosis on bone demineralization and protein catabolism. Small interventional studies support the notion that correcting acidosis slows CKD progression as well. Furthermore, alkaline therapy in persons with CKD and normal bicarbonate levels may also preserve kidney function. Observational studies suggest that targeting a serum bicarbonate level near 28 mEq/L may improve clinical outcomes above and beyond targeting a value ≥ 22 mEq/L, yet values > 26 mEq/L have been reported to be associated with incident heart failure and mortality in the CRIC (Chronic Renal Insufficiency Cohort) Study. Furthermore, correcting acidosis may provoke vascular calcification. This teaching case discusses several uncertainties regarding the management of acidosis in CKD, such as when to initiate alkali treatment, potential side effects of alkali, and the optimum serum bicarbonate level based on current evidence in CKD. Suggestions regarding the maximum sodium bicarbonate dose to administer to patients with CKD to achieve the target serum bicarbonate concentration are offered.

Treatment approaches which are used in the context of inpatient alcoholism treatment are frequently neither theoretically justified nor empirically examined. In view of the enormous method variety the necessity exists for the development of treatment guidelines in order to offer indicators of promising treatment achievement for practitioners and pension funds. In a first step, it must be examined which treatments are effective, which are ineffective and which are possibly even counter-productive. This article aims to give a comprehensive review of randomized-controlled studies/meta-analysis on the efficacy of different treatment approaches. This article reporting the literature review is part of a larger programme to develop clinical practice guidelines for rehabilitation which is supported in form, content and finance by the German Pension Institute for Salaried Employees (Bundesversicherungsanstalt für Angestellte, BfA). Summing up, treatment is effective compared to no treatment. Cognitive behavioural therapy included in a multimodal treatment program is effective. There are a number of treatment protocols for which controlled research has consistently found positive results like social skills training, community reinforcement approaches, behaviour contracting, motivation-enhancing treatment, and family/marital therapy. There is also a number of commonly used treatment approaches that brought neither a positive result or were counter productive like relapse prevention, non-behavioural marital therapy, and insight psychotherapy, confrontational counseling, education, relaxation training, and milieu therapy. Support for matching to a specific treatment is weak, but interventions against alcohol problems should be differentiated according to the severity of the alcohol problem. Since treatment evaluation is mainly accomplished in the US and supplying structures with respect to the US and Germany are substantially different, a generalized transmission of US

Full Text Available Aspermatogenesis is a severe impairment of spermatogenesis in which germ cells are completely lacking or present in an immature form, which results in sterility in approximately 25% of patients. Because assisted reproduction techniques require mature germ cells, biotechnology is a valuable tool for rescuing fertility while maintaining biological fatherhood. However, this process involves, for instance, the differentiation of preexisting immature germ cells or the production/derivation of sperm from somatic cells. This review critically addresses four potential techniques: sperm derivation in vitro, germ stem cell transplantation, xenologous systems, and haploidization. Sperm derivation in vitro is already feasible in fish and mammals through organ culture or 3D systems, and it is very useful in conditions of germ cell arrest or in type II Sertoli-cell-only syndrome. Patients afflicted by type I Sertoli-cell-only syndrome could also benefit from gamete derivation from induced pluripotent stem cells of somatic origin, and human haploid-like cells have already been obtained by using this novel methodology. In the absence of alternative strategies to generate sperm in vitro, in germ cells transplantation fertility is restored by placing donor cells in the recipient germ-cell-free seminiferous epithelium, which has proven effective in conditions of spermatogonial arrest. Grafting also provides an approach for ex-vivo generation of mature sperm, particularly using prepubertal testis tissue. Although less feasible, haploidization is an option for creating gametes based on biological cloning technology. In conclusion, the aforementioned promising techniques remain largely experimental and still require extensive research, which should address, among other concerns, ethical and biosafety issues, such as gamete epigenetic status, ploidy, and chromatin integrity.

Familial hypercholesterolemia (FH) is an autosomal dominant genetic disorder that clinically leads to increased low density lipoprotein-cholesterol (LDL-C) levels. As a consequence, FH patients are at high risk for cardiovascular disease (CVD). Mutations are found in genes coding for the LDLR, apoB, and PCSK9, although FH cannot be ruled out in the absence of a mutation in one of these genes. It is pivotal to diagnose FH at an early age, since lipid lowering results in a decreased risk of cardiovascular complications especially if initiated early, but unfortunately FH is largely underdiagnosed. While a number of clinical criteria are available, identification of a pathogenic mutation in any of the three aforementioned genes is seen by many as a way to establish a definitive diagnosis of FH. It should be remembered that clinical treatment is based on LDL-C levels and not solely on presence or absence of genetic mutations as LDL-C is what drives risk. Traditionally, mutation detection has been done by means of dideoxy sequencing. However, novel molecular testing methods are gradually being introduced. These next generation sequencing-based methods are likely to be applied on broader scale once their efficacy and effect on cost are being established. Statins are the first-line therapy of choice for FH patients as they have been proven to reduce CVD risk across a range of conditions including hypercholesterolemia (though not specifically tested in FH). However, in a significant proportion of FH patients LDL-C goals are not met, despite the use of maximal statin doses and additional lipid-lowering therapies. This underlines the need for additional therapies, and inhibition of PCSK9 and CETP is among the most promising new therapeutic options. In this review, we aim to provide an overview of the latest information about the definition, diagnosis, screening, and current and novel therapies for FH.

Despite the development of more active, less toxic antifungal agents and the standard use of antifungal prophylaxis, invasive fungal infections (especially invasive mold infections continue to be a significant factor in hematopoietic cell and solid organ transplantation outcomes, resulting in high mortality rates. Since the use of fluconazole as standard prophylaxis in the hematopoietic cell transplantation setting, invasive candidiasis has come under control, but no mold-active antifungal agent (except for posaconazole in the setting of acute myelogenous leukemia and myelodysplastic syndrome has been shown to improve the survival rate over fluconazole. With the advent of new azole and echinocandin agents, we have seen the emergence of more azole-resistant and echinocandin-resistant fungi. The recent increase in zygomycosis seen in the hematopoietic cell transplantation setting may be due to the increased use of voriconazole. This has implications for the empiric approach to pulmonary invasive mold infections when zygomycosis cannot be ruled out. It is imperative that an amphotericin B product, an antifungal that has never developed resistance in over 50 years, be initiated. The clinical presentations of invasive mold infections and invasive candidiasis can be nonspecific and the diagnostic tests insensitive, so a high index of suspicion and immediate initiation of empiric therapy is required. Unfortunately, our currently available serologic tests do not predict infection ahead of disease, and, therefore cannot be used to initiate "preemptive" therapy. Also, the Aspergillus galactomannan test gives a false negative

The available forms of psychotherapy for anorexia nervosa (AN) are helpful to many patients; however, a substantial proportion of adults with AN continues to show persistent symptoms and medical risks following treatment. Clinical investigators are therefore developing innovative adjunctive treatments for adults, to augment treatment effects. The 3 cases in this special section each demonstrate a creative, potent adjunctive treatment approach: Exposure and Response Prevention, Cognitive Remediation Therapy, and Unified Couples Therapy. In addition to demonstrating the treatment and response, the authors also discuss the important opportunities and struggles associated with the experience of providing each treatment for AN. Because adults with AN are often very attached to symptoms, and afraid of change, it is crucial to develop a basis for the therapeutic alliance and motivation to change. In these detailed, vivid, evidence-based case examples, the authors demonstrate highly distinct, innovative approaches to these issues. (PsycINFO Database Record

Reviews of currently empirically supported treatments for post-traumatic stress disorder (PTSD) show that despite their efficacy for many patients, these treatments have high nonresponse and dropout rates. This article develops arguments for the value of psychodynamic approaches for PTSD, based on a review of the empirical psychopathology and treatment literature. Psychodynamic approaches may help address crucial areas in the clinical presentation of PTSD and the sequelae of trauma that are not targeted by currently empirically supported treatments. They may be particularly helpful when treating complex PTSD. Empirical and clinical evidence suggests that psychodynamic approaches may result in improved self-esteem, increased ability to resolve reactions to trauma through improved reflective functioning, increased reliance on mature defenses with concomitant decreased reliance on immature defenses, the internalization of more secure working models of relationships, and improved social functioning. Additionally, psychodynamic psychotherapy tends to result in continued improvement after treatment ends. Additional empirical studies of psychodynamic psychotherapy for PTSD are needed, including randomized controlled outcome studies.

Complex implant rehabilitations can include procedures requiring multiple phases of treatment, commonly referred to as staged approaches. The reasons for staged approaches are varied but usually involve serial extraction of hopeless teeth. These treatment plans both enable the patient to avoid removable prostheses by keeping natural teeth during healing phases, and circumvent the immediate loading of some implants placed in grafted bone. One major disadvantage to serial extraction in a staged approach is the potential for gingival changes. These changes include gingival recession around abutments that can affect the gingival profile around the finished case. This article discusses varying approaches for dealing with these gingival changes and suggests protocol modifications during the implant treatment-planning phase.

This approach to the treatment of BPD is part of a general framework for treating all forms of personality disorder. The therapeutic model has two components: (1) general strategies to manage core self and interpersonal pathology that characterizes all cases of personality disorder and (2) a specific or tailored component required to treat the problems of individual cases. The general strategies, derived from generic models of therapeutic change and self-psychology, emphasize the therapeutic relationship and the importance of a consistent treatment process, validation, and building motivation. A combination of specific interventions, including medication and psychotherapeutic strategies drawn from treatment approaches, is incorporated into this framework as required. The overall model is not an eclectic approach to treatment but an integrated framework based on an understanding of borderline pathology that emerges from recent research.
Full Text Available This case report describes the treatment of a 23-year-old female with severe bimaxillary dentoalveolar protrusion and missing left mandibular first molar. Her chief concern was significant facial convexity. Generally treatment plan of such cases involves extraction of first premolars but absence of first molar complicates situation with problem of space management, anchorage requirement and post-treatment occlusion. This case report introduces thought provoking treatment approach of selecting atypical teeth for orthodontic extraction without compromising the quality of treatment outcomes. However, three first bicuspids were extracted while the mandibular left second premolar was distalized into the missing molar space and used as an abutment for replacement of the missing first molar by prosthesis. Despite the unusual asymmetric extraction of teeth, superimposition of the pretreatment and post-treatment cephalometric tracings shows excellent treatment outcomes and reduction of facial convexity by maximum retraction of the anterior teeth.

Patients with a compromised periodontal condition and a breakdown in occlusal support may require periodontal and prosthodontic treatment in conjunction with orthodontic treatment. Orthodontic treatment of these patients is possible and would involve removal of inflammation and occlusal interference and provision of an environment for proper restorative rehabilitation. A different approach to the orthodontic treatment of these patients is required in terms of treatment manner, stabilizing anchorage systems, force systems, retention, and plaque control during treatment. This report describes the case of a 49-year-old woman with severely compromised periodontal tissues, multiple missing teeth, and malocclusion. Highly esthetic and functional results were achieved by treatment with orthodontics as well as periodontal therapy, including guided tissue regeneration and implant restoration with sinus lift.

Because of the limitations of surgical resection, thermal ablation is commonly used for the treatment of hepatocellular carcinoma and liver metastases. Current methods of ablation can result in marginal recurrences of larger lesions and in tumors located near large vessels. This review presents a novel approach for extending treatment out to the margins where temperatures do not provide complete treatment with ablation alone, by combining thermal ablation with drug-loaded thermosensitive liposomes. A history of the development of thermosensitive liposomes is presented. Clinical trials have shown that the combination of radiofrequency ablation and doxorubicin-loaded thermosensitive liposomes is a promising treatment.
Full Text Available Passive control devices based on casing treatments have already shown their capability to improve the flow stability in axial compressors. However, their optimization remains complex due to a partial understanding of the related physical mechanisms. In order to quantitatively assess the interaction between slots and the blade tip flow, the present paper develops a novel analysis methodology based on a control-volume approach located in the rotor tip region. This methodology may be used for analyzing the casing treatment based on both axi- and non-axisymmetric slots design. The second issue of the paper focuses on the application of the current approach to better understand the effects of axi- and non-axisymmetric grooves in three different axial compressors which differ by the flow regime (subsonic/transonic and the smooth casing shape (cylindrical/concave. Numerical simulations are performed, and results of the current approach with and without casing treatments are compared.

The dose-volume histogram (DVH) is a clinically relevant criterion to evaluate the quality of a treatment plan. It is hence desirable to incorporate DVH constraints into treatment plan optimization for intensity modulated radiation therapy. Yet, the direct inclusion of the DVH constraints into a treatment plan optimization model typically leads to great computational difficulties due to the non-convex nature of these constraints. To overcome this critical limitation, we propose a new convex-moment-based optimization approach. Our main idea is to replace the non-convex DVH constraints by a set of convex moment constraints. In turn, the proposed approach is able to generate a Pareto-optimal plan whose DVHs are close to, or if possible even outperform, the desired DVHs. In particular, our experiment on a prostate cancer patient case demonstrates the effectiveness of this approach by employing two and three moment formulations to approximate the desired DVHs.

Mandibular angle fractures continue to be a common type of facial injury. The objectives in treatment are to effect rapid healing by anatomic reduction and fixation and to restore function and appearance with minimal disability and complications. Traditionally, when open techniques are utilised, the extra-oral approach is performed through a skin incision concealed in the submandibular crease. However, patients develop unsightly scars and there is a risk of injury to the marginal mandibular nerve. In comparison, the trans-oral approach, performed through an oral mucosal incision, results in minimal external scarring or injury to the marginal mandibular nerve and allows direct visualisation and confirmation of the desired occlusion during the placement of the miniplates. The basic aim of the study was to provide a treatment for the mandibular fractures which results in minimal scarring and fulfills all the functional needs of the patient. Patients coming to KLES PK Hospital and MRC with mandibular angle fractures requiring open reduction and internal fixation admitted under OMFS were taken for the study. The sample size of the study was 15. In one group, the patients were treated by extra-oral approach and the other group by transbuccal approach. In patients treated by transbuccal approach, special armamentarium consisting of trocar, cannula, and cheek retractor were used; and in both the groups, semirigid fixation was done using two miniplates with around a distance of 1cm. Total of 15 patients were treated, 10 with transbuccal approach and 5 with submandibular approach. It has been found that both techniques fulfill the functional requirements of the patients. Patients treated with submandibular approach developed obvious unsightly scars, whereas transbuccal approach results in minimal scarring. The results associated with clinical observations suggest that transbuccal approach is a superior and less time consuming approach than extraoral approach, but it requires

The ideal treatment strategy for Crohn's disease (CD)remains uncertain,as does the optimal endpoint of therapy.Top-down versus step-up describes two different approaches:early use of immunomodulators and biological agents in the former versus initial treatment with steroids in the latter,with escalation to immunomodulators or biological drugs in patients proven to be steroid refractory or steroid dependent.Top-down therapy has been associated with higher rates of mucosal healing.If mucosal healing proves to be associated with better long-term outcomes,such as a decreased need for hospitalization and surgery,top-down therapy may be the better approach for many patients.The main concern with the top-down approach is the toxicity of the immunomodulators and biological agents,which have been linked with infectious complications as well as an increased risk of lymphoma.It is unlikely that one strategy will be best for all patients given the underlying heterogeneity of CD presentation and severity.Ultimately,we must weigh the safety and efficacy of the therapies with the risks of the disease itself.Unfortunately our ability to risk stratify patients at diagnosis remains rudimentary.The purpose of this paper is to review the data that supports or refutes the differing treatment paradigms in CD,and to provide a rationale for an approach,termed the "accelerated step-up" approach,which attempts to balance the risks and benefits of our currently available therapies with the risk of disease related complications as we understand them in 2008.

Marginal structural Cox models are used for quantifying marginal treatment effects on outcome event hazard function. Such models are estimated using inverse probability of treatment and censoring (IPTC) weighting, which properly accounts for the impact of time-dependent confounders, avoiding conditioning on factors on the causal pathway. To estimate the IPTC weights, the treatment assignment mechanism is conventionally modeled in discrete time. While this is natural in situations where treatment information is recorded at scheduled follow-up visits, in other contexts, the events specifying the treatment history can be modeled in continuous time using the tools of event history analysis. This is particularly the case for treatment procedures, such as surgeries. In this paper, we propose a novel approach for flexible parametric estimation of continuous-time IPTC weights and illustrate it in assessing the relationship between metastasectomy and mortality in metastatic renal cell carcinoma patients.

Full Text Available Complex cavernous sinus fistulae (CCF are still a technical challenge to neurovascular team. The most commonly performed treatment consists in endovascular embolization of the lesion through an arterial or venous approach. Not always these conventional routes are feasible, requiring alternative routes. We report a case of a 44-year-old woman with a complex indirect (Barrow D carotid cavernous sinus fistula treated by two interventional sessions that imposing a retrograde direct transvenous approach via the superior ophthalmic vein.
Physiotherapy for the treatment of vaginismus is perceived as an intervention aimed to normalize muscle tone of the pelvic floor in order to allow vaginal penetration in accordance with the traditional view of vaginal spasm as its defining feature. Newer definitions recognize the experience of anxiety as well as pain, and effective treatment approaches should address these components as well. Physiotherapists often encounter women who, as a result of severe anxiety, are unable to undergo examination and treatment, despite their expressed desire to do so. This article describes a therapeutic intervention designed to help women with vaginismus prepare for examination and treatment by addressing the component of anxiety in real-life situations. This approach is also appropriate for nurse practitioners and physicians who work with this patient population and may be adapted for sex therapists to teach as a home exercise.

Constructed wetlands (CWs) for wastewater treatment have evolved substantially over the last decades and have been recognized as an effective means of "green technology" for wastewater treatment. This paper reviews the numerous modeling approaches ranging from simple first-order models to more complex dynamic models of treatment behaviour in CWs. The main objective of the modeling work is to better understand the process in CWs and optimize design criteria. A brief study in this review discusses the efforts taken to describe the process-based model for the efficient removal of pollutants in CWs. Obtaining better insights is essential to understand the hydraulic and biochemical processes in CWs. Currently, employed modeling approaches can be seen in two categories, i.e. "black-box models" and "process-based models". It is evident that future development in wetland technology will depend on improved scientific knowledge of internal treatment mechanisms.

Leather industries are key contributors in the economy of many developing countries, but unfortunately they are facing serious challenges from the public and governments due to the associated environmental pollution. There is a public outcry against the industry due to the discharge of potentially toxic wastewater having alkaline pH, dark brown colour, unpleasant odour, high biological and chemical oxygen demand, total dissolved solids and a mixture of organic and inorganic pollutants. Various environment protection agencies have prioritized several chemicals as hazardous and restricted their use in leather processing however; many of these chemicals are used and discharged in wastewater. Therefore, it is imperative to adequately treat/detoxify the tannery wastewater for environmental safety. This paper provides a detail review on the environmental pollution and toxicity profile of tannery wastewater and chemicals. Furthermore, the status and advances in the existing treatment approaches used for the treatment and/or detoxification of tannery wastewater at both laboratory and pilot/industrial scale have been reviewed. In addition, the emerging treatment approaches alone or in combination with biological treatment approaches have also been considered. Moreover, the limitations of existing and emerging treatment approaches have been summarized and potential areas for further investigations have been discussed. In addition, the clean technologies for waste minimization, control and management are also discussed. Finally, the international legislation scenario on discharge limits for tannery wastewater and chemicals has also been discussed country wise with discharge standards for pollution prevention due to tannery wastewater.

This article describes an integrated approach to the treatment of velopharyngeal insufficiency, aimed in improving the anatomical and physiological function of velopharyngeal ring. Velopharyngeal ring is considered as the nervemuscle complex in the treatment of patients with this pathology. It is shown that a one-time complex treatment of velopharyngeal insufficiency, estimated with the program «Compare» in the below-described clinical example, increased velopharyngeal closure ring by 25%, thus eliminating nasality and significantly improve the quality of speech.
The interaction between mother and child helds a central position in in- and outpatient treatment of postpartal depressive mothers. Infants are highly sensitive towards the emotional state of their mothers and other attachment figures. This sensivity is essential for the comprehension of the influence of a psychiatric illness of the mother on child development Postpartal depression as the most common psychiatric illness in young mothers takes a central part. The specific situation of young depressive mothers demands an adaptation of the therapeutic treatment. Different approaches towards the treatment of postpartal depression with respect to the mother-child interaction are elucidated.

The aim of the study was to evaluate the feasibility of a limited invasive approach for the treatment of upper thoracic spine disease. Seven patients with type-A thoracic fractures and three with tumors underwent long thoracic stabilization through a minimally invasive approach. Four patients underwent a completely percutaneous approach while the other three underwent a modified hybrid technique, a combination of percutaneous and open approach. The hybrid constructs were realized using a percutaneous approach to the spine distally to the spinal lesion and by open approach proximally. In two patients, the stabilization was extended proximally up to the cervical spine. Clinical and radiographic assessment was performed during the first year after the operation at 3, 6, and 12 months. No technically related complications were seen. The postoperative recovery was rapid even in the tumor patients with neurologic impairment. Blood loss was irrelevant. At one-year follow-up there was no loosening or breakage of the screws or failure of the implants. When technically feasible a completely percutaneous approach has to be taken in consideration; otherwise, a combined open-percutaneous approach could be planned to minimize the invasivity of a completely open approach to the thoracic spine.

In this study the levels of 19 drugs of abuse were estimated throughout a wastewater treatment plant using polar organic chemical integrative samplers (POCIS), 24h composite samples and grab samples. Overall removal efficiencies and removals in between each treatment unit were calculated using load data for each sampling technique as well as removals that take into account the hydraulic residence time distribution of the treatment plant (time-shifted mass balancing approach). Amphetamine-type stimulants, cocaine and its major metabolite, benzoylecgonine and opioid levels determined with 24h composite samples were generally comparable to those obtained with POCIS and grab samples. Negative mass balances resulting from the estimation of overall removal efficiencies by POCIS, day-to-day mass balancing of 24h composite and grab sample data did not occur when the hydraulic retention time (HRT) distributions of the plant were taken into account for calculation. Among the compounds investigated, cocaine exhibited the highest overall removal (90%) while codeine had the lowest with 13%, respectively. Sampling between the treatment units revealed that highest removal occurs during biological treatment as compared to primary or secondary clarification. Methylenedioxyamphetamine (MDA), fentanyl, dihydrocodeine and heroin were not detected in wastewater at any of the sampling locations at the treatment plant regardless of the sampling technique. The study demonstrates the benefits of applying the time-shifted mass balancing approach to the calculation of removals of drugs of abuse during wastewater treatment.

Full Text Available Introduction. Ventricular septal rupture (VSR in the acute myocardial infarction (AMI is a rare but very serious complication, still associated with high mortality, despite significant improvements in pharmacological and surgical treatment. Therefore, hybrid approaches are introduced as new therapeutical options. Case Outline. We present an urgent hybrid approach, consisting of the initial percutaneous coronary intervention (PCI of the infarct-related artery, followed by immediate surgical closure of the ventricular septal rupture, for treatment of high risk, hemodynamically unstable female patient with AMI caused by one-vessel disease and complicated by VSR and cardiogenic shock. Since the operative risk was also very high (EUROSCORE II 37%, this therapeutic decision was based on the assumption that preoperative PCI could promptly establish blood flow and thereby lessen the risks, duration and complexity of urgent cardiosurgical intervention, performed on the same day. This approach proved to be successful and the patient was discharged from the hospital on the fifteenth postoperative day in stable condition. Conclusion. In selected cases, with high operative risk and unstable hemodynamic state due to AMI complicated by VSR, urgent hybrid approach consisting of the initial PCI followed by surgical closure of VSR may represent an acceptable treatment option and contribute to the treatment of this complex group of patients.

Alzheimer's disease is a serious degenerative disease which is mainly typical of the developed countries. The prevalence percentage in Africa is only 2.6 %, whereas in America it is 6.5 % and in Western Europe 7.2 %. Overall, this disease affects 44 million people worldwide. With respect to the demographic development, a number of people suffering from Alzheimer's disease is expected in future. The key issue is not only the discovery of an effective medication, but also the early diagnosis, prevention and care about people with AD, as well as the provision of an equivalent rise of places in health and social institutions. Since the treatment of Alzheimer's disease (AD) imposes a severe economic and social burden, the main purpose of this study is to analyze and compare available non-pharmacological approaches to the prevention and treatment of patients with AD with special focus on their cognitive competences. In addition, the analysis also concentrates on the costs of pharmacological care in individual countries all over world. This is done by using Drummond's methodological approaches to direct and indirect costs. The analysis of non-pharmacological approaches is conducted on the basis of literature review of both clinical and review studies relevant for the research issue in the acknowledged databases and a comparison and evaluation of their findings.

Hydraulic fracturing results in large volumes of wastewater, called "produced water". Treatment of produced water is challenged by its high salt, organic compound, and radionuclide concentrations. Current disposal approaches include deep well injection and physical-chemical treatment for surface disposal; however, deep well injection has been recently linked to induced seismicity and physical-chemical treatments suffer from fouling and high cost. The reuse of the produced water has emerged as a desirable management option; however, this requires pretreatment to generate a water of usable quality and limit microbial activity. Biological treatment is an underexplored area in produced water management and has the potential to remove organics and reduce overall costs for physiochemical treatment or reuse. Suspended growth biological treatment techniques are known to be limited by salinity motivating a more robust biofilm approach: 'microbial mats'. In this study, we used engineered microbial mats as a biofilm treatment for the produced water. Evaluation of the biodegradation performance of microbial mats in synthetic and real produced waters showed microbial activity at up to 100,000 mg/L TDS concentration (three times the salt concentration of the ocean). Organic removal rates reached to 1.45 mg COD/gramwet-day at 91,351 mg/L TDS in real produced water samples and initial evaluation demonstrated the potential for field-scale application. Metagenomic analyses of microbial mats demonstrated an adaptive shift in the microbial community treating different samples, suggesting the wide applicability of this treatment approach for produced waters with varying chemical composition. On-going studies focus on the evaluation of the removal of the organics and the contaminants of high concern in produced water using microbial mats as well as the effect of the biofilm growth conditions on the biodegradation in changing salt concentrations.

Cosmetic, functional, and structural sequelae of scarring are innumerable, and measures exist to optimize and ultimately minimize these sequelae. To evaluate the innumerable methods available to decrease the cosmetic, functional, and structural repercussions of scarring, pubMed search of the English literature with key words scar, scar revision, scar prevention, scar treatment, scar remodeling, cicatrix, cicatrix treatment, and cicatrix remodeling was done. Original articles and reviews were examined and included. Seventy-nine manuscripts were reviewed. Techniques, comparisons, and results were reviewed and tabulated. Overall, though topical modalities are easier to use and are usually more attractive to the patient, the surgical approaches still prove to be superior and more reliable. However, advances in topical medications for scar modification are on the rise and a change towards medical treatment of scars may emerge as the next best approach. Comparison studies of the innumerable specific modalities for scar revision and prevention are impossible. Standardization of techniques is lacking. Scarring, the body's natural response to a wound, can create many adverse effects. At this point, the practice of sound, surgical fundamentals still trump the most advanced preventative methods and revision techniques. Advances in medical approaches are available, however, to assist the scarring process, which even the most advanced surgical fundamentals will ultimately lead to. Whether through newer topical therapies, light treatment, or classical surgical intervention, our treatment armamentarium of scars has expanded and will allow us to maximize scar prevention and to minimize scar morbidity.

AMBIT (Adolescent Mentalization-Based Integrative Treatment) is a developing team approach to working with hard-to-reach adolescents. The approach applies the principle of mentalization to relationships with clients, team relationships and working across agencies. It places a high priority on the need for locally developed evidence-based practice, and proposes that outcome evaluation needs to be explicitly linked with processes of team learning using a learning organization framework. A number of innovative methods of team learning are incorporated into the AMBIT approach, particularly a system of web-based wiki-formatted AMBIT manuals individualized for each participating team. The paper describes early development work of the model and illustrates ways of establishing explicit links between outcome evaluation, team learning and manualization by describing these methods as applied to two AMBIT-trained teams; one team working with young people on the edge of care (AMASS - the Adolescent Multi-Agency Support Service) and another working with substance use (CASUS - Child and Adolescent Substance Use Service in Cambridgeshire). Measurement of the primary outcomes for each team (which were generally very positive) facilitated team learning and adaptations of methods of practice that were consolidated through manualization. © The Author(s) 2014.
Full Text Available Pediatric acetabular fractures are rare, and anterior column fractures are even rarer. Generally, conservative treatment is applied. If there is displacement of more than 2 mm or findings of instability or fragments within the joint, then surgical treatment is applied. Anterior and posterior approaches may be used in surgical treatment. With pediatric patients, even greater care should be taken in the choice of surgery to be performed according to the fracture pattern to avoid postoperative triradiate cartilage damage. Therefore, minimally invasive surgery is more appropriate. We herein present a case of an acetabulum anterior column posterior hemitransverse fracture following a traffic accident, which was treated surgically using a modified Stoppa (technique approach.

Full Text Available Introduction. No consensus has been reached yet on the surgical approach for treatment of condylar fractures. Objective. The aim of this study was to present modified Risdon approach (without facial nerve identification in the treatment of subcondylar mandibular fractures. Method. This is a retrospective study of a period 2005-2012. During this seven-year period, 25 condylar mandibular fractures in 22 men and three women (19-68 years old were treated by modified Risdon approach without identifying the facial nerve. The main inclusion criterion was subcondylar fracture according to Lindahl classification. Results. No additional morbidity related to postoperative complications, such as infection or salivary fistula, was observed in this series. Only two (8% patients developed temporary weakness of the marginal branch of the facial nerve, which resolved six weeks postoperatively. Each patient achieved good mouth opening postoperatively. Scar was camouflaged in the first cervical wrinkle. Two patients developed temporomandibular joint dysfunction. No patient had postoperative occlusal disturbance. In all of the patients good aesthetic result was achieved in a two-year follow-up. Conclusion. In comparison with techniques described in the literature, the main advantages of the modified Risdon approach are the following: no need for facial vessels identification; direct, fast, and safe approach to mandibular angle and subcondylar region; relatively simple surgical technique and good cosmetic result - due to aesthetically placed incision. This approach could be recommended for subcondylar fracture as a simplified and safe procedure. [Projekat Ministarstva nauke Republike Srbije, br. 175075

The extended Kalman filter (EKF) is the nonlinear model of a Kalman filter (KF). It is a useful parameter estimation method when the observation model and/or the state transition model is not a linear function. However, the computational requirements in EKF are a difficulty for the system. With the help of cognition-based designation and the Taylor expansion method, a novel algorithm is proposed to ease the computational load for EKF in azimuth predicting and localizing under a nonlinear observation model. When there are nonlinear functions and inverse calculations for matrices, this method makes use of the major components (according to current performance and the performance requirements) in the Taylor expansion. As a result, the computational load is greatly lowered and the performance is ensured. Simulation results show that the proposed measure will deliver filtering output with a similar precision compared to the regular EKF. At the same time, the computational load is substantially lowered.

This research sought to compare the effectiveness of three landfill enhanced treatment approaches aimed at removing releasable carbon and nitrogen after anaerobic landfilling including flushing with clean water (FB 1), leachate recirculation with ex-situ treatment (FB 2), and leachate recirculation with ex-situ treatment and in-situ aeration (FB 3). After extensive treatment of the waste in the FB scenarios, the overall solids and biodegradable fraction were reduced relative to the mature anaerobically treated waste. In terms of the overall degradation, aeration did not provide any advantage over flushing and anaerobic treatment. Flushing was the most effective approach at removing biodegradable components (i.e. cellulose and hemicellulose). Leachate quality improved for all FBs but through different mechanisms. A significant reduction in ammonia-nitrogen occurred in FB 1 and 3 due to flushing and aeration, respectively. The reduction of chemical oxygen demand (COD) in FB 1 was primarily due to flushing. Conversely, the reduction in COD in FBs 2 and 3 was due to oxidation and precipitation during Fenton's Reagent treatment. A mass balance on carbon and nitrogen revealed that a significant fraction still remained in the waste despite the additional treatment provided. Carbon was primarily converted biologically to CH4 and CO2 in the FBs or removed during treatment using Fenton's Reagent. The nitrogen removal occurred through leaching or biological conversion. These results show that under extensive treatment the waste and leachate characteristics did meet published stability values. The minimum stability values achieved were through flushing although FB 2 and 3 were able to improve leachate quality and solid waste characteristics but not to the same extent as FB 1.

Objective:The main treatment method used for thoracolumbar fractures is open reduction and internal fixation.Commonly there are three surgical approaches:anterior,posterior and paraspinal.We attempt to compare the three approaches based on our clinical data analysis.Methods:A group of 94 patients with Denis type A or B thoracolumbar burst fracture between March 2008 and September 2010 were recruited in this study.These patients were treated by anterior-,posterior-or paraspinal-approach reduction with or without decompression.The fracture was fixed with titanium mesh and Z-plate via anterior approach (24 patients),screw and rod system via posterior approach (38 patients) or paraspinal approach (32 patients).Clinical evaluations included operation duration,blood loss,incision length,preoperative and postoperative Oswestry disability index (ODI).Results:The average operation duration (94.1 min±13.7min),blood loss (86.7 ml±20.0 ml),length of incision (9.3mm± 0.7 mm) and postoperative ODI (6±0.5) were significandy lower (P＜0.05) in paraspinal approach group than in traditional posterior approach group (operation duration 94.1 min±13.7 min,blood loss 143.3 ml±28.3 ml,length of incision 15.4 cm±2.1 cm and ODI 12±0.7) and anterior approach group (operation duration 176.3 min±20.7 min,blood loss 255.1 m1±38.4 ml,length of incision 18.6 cm±2.4 cm and OD113±2.4).There was not statistical difference in terms of Cobb angle on radiographs among the three approaches.Conclusion:The anterior approach surgery is convenient for resection of the vertebrae and reconstruction of vertebral height,but it is more complicated and traumatic.Hence it is mostly used for severe Denis type B fracture.The posterior approach is commonly applied to most thoracolumbar fractures and has fewer complications compared with the anterior approach,but it has some shortcomings as well.The paraspinal approach has great advantages compared with the other two approaches.It is in accordance with

The first generation of young men using primary prophylaxis is coming of age. Important questions regarding the management of severe haemophilia with prophylaxis persist: Can prophylaxis be stopped? At what age? To what effect? Can the regimen be individualized? The reasons why some individuals discontinue or poorly comply with prophylaxis are not well understood. These issues have been explored using predominantly quantitative research approaches, yielding little insight into treatment decision-making from the perspectives of persons with haemophilia (PWH). Positioning the PWH as a source of expertise about their condition and its management, we undertook a qualitative study: (i) to explore and understand the lived experience of young men with severe haemophilia A or B and (ii) to identify the factors and inter-relationships between factors that affect young men's treatment decision-making. This manuscript reports primarily on the second objective. A modified Straussian, grounded theory methodology was used for data collection (interviews) and preliminary analysis. The study sample, youth aged 15-29, with severe haemophilia A or B, was chosen selectively and recruited through three Canadian Haemophilia Treatment Centres. We found treatment decision-making to be multi-factorial and used the Framework method to analyze the inter-relationships between factors. A typology of four distinct approaches to treatment was identified: lifestyle routine prophylaxis, situational prophylaxis, strict routine prophylaxis and no prophylaxis. Standardized treatment definitions (i.e.: 'primary' and 'secondary', 'prophylaxis') do not adequately describe the ways participants treat. Naming the variation of approaches documented in this study can improve PWH/provider communication, treatment planning and education.

Membrane bioreactor (MBR) technology is a very reliable and extensively tested solution for biological wastewater treatment. Nowadays, separate treatment of highly polluted wastewater streams especially from hospitals and other health care facilities is currently under investigation worldwide. In this context, the MBR technology will play a decisive role because an effluent widely cleaned up from solids and nutrients is absolutely mandatory for a subsequent further elimination of organic trace pollutants. Taking hospital wastewater as an example, the aim of this study was to investigate to what extent MBR technology is an adequate 'pre-treatment' solution for further elimination of trace pollutants. Therefore, we investigated - within a 2-year period - the performance of a full-scale hospital wastewater treatment plant (WWTP) equipped with a MBR by referring to conventional chemical and microbiological standard parameters. Furthermore, we measured the energy consumption and tested different operating conditions. According to our findings the MBR treatment of the hospital wastewater was highly efficient in terms of the removal of solids and nutrients. Finally, we did not observe any major adverse effects on the operation and performance of the MBR system which potentially could derive from the composition of the hospital wastewater. In total, the present study proved that MBR technology is a very efficient and reliable treatment approach for the treatment of highly polluted wastewater from hospitals and can be recommended as a suitable pre-treatment solution for further trace pollutant removal.

Baseline measures of naming nouns and verbs in single words, and sentences, were obtained. While there was no improvement in production of nouns or verbs in single words or sentence production after sham tDCS, and no improvement of noun production after anodal tDCS and speech-language treatment, production of verbs in sentences improved after a 10-session treatment block of anodal tDCS and behavioral therapy. Conclusion Administering a behavioral treatment that is impairment-based as well as functionally-based in conjunction with tDCS is both feasible and promising. Anodal tDCS in conjunction with behavioral intervention is a treatment approach that warrants continued investigation. The results will be discussed in relation to the tDCS and aphasia literature.
Full Text Available The research goals include: 1 assessment the quality of life of those patients who have defects of tooth rows not replaced by orthopedic appliances on the basis of the complex analysis; 2 choice of more reasonable method of treatment. The use of dental questionnaires such as Oral Health Impact Profile-14 (OHIP-14 while treating oral pathology allows both optimizing an approach to choosing an appropriate treatment method and making more successful prognosis as to the efficiency of treatment being performed. The quality of life of those patients who have tooth rows defects not replaced by orthopedic appliances depends on sex, age, family status, employment and extent of tooth rows defects. Patients with tooth rows defects not replaced by orthopedic appliances accompanied by diseases of peri-odontium are characterized by worse quality of life. This fact must be taken into consideration while planning patients' treatment
Full Text Available Treatment-resistant depression is associated with significant disability and, due to its high prevalence, results in substantive economic and societal burden at a population level. The objective of this study is to synthesize extant literature on approaches currently being applied to understand and address this condition. It is hoped that the findings can be used to inform practitioners and guide future research. A scoping review of the scientific literature was conducted with findings categorized and charted by underlying research paradigm. Currently, the vast majority of research stems from a biological paradigm (81%. Research on treatment-resistant depression would benefit from a broadened field of study. Given that multiple etiological mechanisms likely contribute to treatment-resistant depression and current efforts at prevention and treatment have substantial room for improvement, an expanded research agenda could more effectively address this significant public health issue.

We consider the problem of intensity-modulated radiation therapy (IMRT) treatment planning using direct aperture optimization. While this problem has been relatively well studied in recent years, most approaches employ a heuristic approach to the generation of apertures. In contrast, we use an exact approach that explicitly formulates the fluence map optimization (FMO) problem as a convex optimization problem in terms of all multileaf collimator (MLC) deliverable apertures and their associated intensities. However, the number of deliverable apertures, and therefore the number of decision variables and constraints in the new problem formulation, is typically enormous. To overcome this, we use an iterative approach that employs a subproblem whose optimal solution either provides a suitable aperture to add to a given pool of allowable apertures or concludes that the current solution is optimal. We are able to handle standard consecutiveness, interdigitation and connectedness constraints that may be imposed by the particular MLC system used, as well as jaws-only delivery. Our approach has the additional advantage that it can explicitly account for transmission of dose through the part of an aperture that is blocked by the MLC system, yielding a more precise assessment of the treatment plan than what is possible using a traditional beamlet-based FMO problem. Finally, we develop and test two stopping rules that can be used to identify treatment plans of high clinical quality that are deliverable very efficiently. Tests on clinical head-and-neck cancer cases showed the efficacy of our approach, yielding treatment plans comparable in quality to plans obtained by the traditional method with a reduction of more than 75% in the number of apertures and a reduction of more than 50% in beam-on time, with only a modest increase in computational effort. The results also show that delivery efficiency is very insensitive to the addition of traditional MLC constraints; however, jaws

Gummy smile cases are always esthetically demanding cases. This article presents a case treated with an interdisciplinary treatment approach and Digital Smile Approach (DSA) using Keynote (DSA), to predictably achieve an esthetic outcome for a patient with gummy smile. The importance of using questionnaires and checklists to facilitate the gathering of diagnostic data cannot be overemphasized. The acquired data must then be transferred to the design of the final restorations. The use of digital smile design has emerged as a powerful tool in cosmetic dentistry to help both practitioner and patient visualize the final outcome.

Kaiser Permanente, an integrated health care delivery system in the USA, takes a "whole systems" approach to the chronic disease of obesity that begins with efforts to prevent it by modifying the environment in communities and schools. Aggressive case-finding and substantial investment in intensive lifestyle modification programs target individuals at high risk of diabetes and other weight-related conditions. Kaiser Permanente regions are increasingly standardizing their approach when patients with obesity require treatment intensification using medically supervised diets, prescription medication to treat obesity, or weight loss surgery.
Full Text Available Behçet's disease (BD is a chronic, relapsing, and debilitating systemic vasculitis of unknown aetiology with the clinical features of mucocutaneous lesions, ocular, vascular, articular, neurologic, gastrointestinal, urogenital, and pulmonary involvement. The disease is much more frequent along the ancient “Silk Route” extending from Eastern Asia to the Mediterranean basin, compared with Western countries. The disease usually starts around the third or fourth decade of life. Male sex and a younger age of onset are associated with more severe disease. Although the treatment has become much more effective in recent years, BD is still associated with severe morbidity and considerable mortality. The main aim of the treatment should be the prevention of irreversible organ damage. Therefore, close monitoring, early, and appropriate treatment is mandatory to reduce morbidity and mortality. The treatment is mainly based on the suppression of inflammatory attacks of the disease using immunomodulatory and immunosuppressive agents. In this paper, current state of knowledge regarding the therapeutic approaches is outlined. To provide a rational framework for selecting the appropriate therapy along the various treatment choices, a stepwise, symptom-based, evidence-based algorithmic approach was developed.
During recent years growing attention has been paid to psychiatric comorbidities in epilepsy. However, anxiety disorders still remain underrecognized and undertreated. This is largely related to the lack of specific screening instruments and the frequent co-occurrence with mood disorders. Data on treatment are insufficient and clinical practice still relies heavily on individual experience. In this article we review evidence-based treatment strategies for primary major anxiety disorders and adapt them to the specific needs of patients with epilepsy. In panic disorder, a combined approach, namely serotonin-reuptake inhibitors (SSRIs) and cognitive behavioral therapy (CBT) is always indicated during the acute phase. Long-term maintenance treatment may include combined therapy or CBT alone depending on individual cases. For generalized anxiety disorders pregabalin has to be considered first choice for short-term and long-term treatment. In social anxiety disorder and posttraumatic stress disorder SSRIs, in particular sertraline and paroxetine, can be safely used. Obsessive-compulsive disorder represents a serious condition that needs to be approached in a psychiatric setting. CBT should be considered as the first choice in patients with epilepsy. If drug treatment is needed, epileptologists have to be aware that high-dose antidepressants are appropriate and that SSRIs, in particular sertraline, should be considered first choice. In these patients, careful clinical monitoring is indicated, in selected cases, for potential seizure precipitation and side effects due to pharmacodynamics interactions.

Using multidimensional scaling (MDS) analysis, this study examined how patient conceptualisations of treatment motivation compare with theoretically based assumptions used in current assessment approaches. Patients undergoing antiretroviral therapy for HIV/AIDS (n=39) rated for similarity between all possible pairings of 23 treatment descriptions, including descriptors of intrinsic, extrinsic, approach and avoidance motivation. MDS analyses revealed that patient perceptions of intrinsic and extrinsic motivations often differ from those based on definitions derived from common interpretations of self-determination theory. Findings also showed that patients reported motivation for avoiding treatment when they associated their medication regimens with side effects and other negatively valenced outcomes. The study describes new applications of MDS in assessing how patients perceive the relationship between treatment behaviours and specific forms of motivation, such as intrinsic and extrinsic motivations. In addition, the study suggests how MDS may be used to develop behavioural strategies aimed at helping patients follow their regimens consistently by identifying treatment conceptualisations and contexts that facilitate or impede adherence.

Full Text Available The traditional orthodontic patient-base of adolescents has changed dramatically over the last 20 years. Adult patients now comprise a very large percentage of the orthodontic patient base. These patients bring with them unique challenges to the provision of aesthetic treatment. Gingival aesthetics, for a long time the exclusive concern of the periodontist, has now become one of the chief aesthetic challenges presented to the practicing orthodontist. This report illustrates the interdisciplinary approach in a patient requiring periodontic, orthodontic and prosthodontic treatment.

Women who use tobacco, alcohol and drugs during pregnancy are at increased risk of maternal and fetal morbidity. Universal screening using empirically validated approaches can improve identification of substance-using pregnant women and facilitate comprehensive assessment of treatment needs. There is strong evidence for effectiveness of psychosocial and behavioral substance abuse treatments across a range of intensities and levels of care. In addition to addressing substance use, services for co-occurring psychiatric disorders, trauma exposure, and prenatal care are important components of coordinated systems of care. More research on and greater access to evidence-based interventions is needed for this underserved population.

Missing maxillary lateral incisors create an esthetic problem with specific orthodontic and prosthetic considerations. Implants are commonly used to replace congenitally missing lateral incisors in adolescent orthodontic patients. However, an interdisciplinary approach should be observed during the diagnosis, prognosis, and treatment plan to provide a result with good predictability and meet the esthetic and functional expectations of the patient. The present study describes a case of a young patient with tooth agenesis of maxillary lateral incisors, which was conducted with an integrated planning. After 5-year follow-up of 2 fixed implant-supported prostheses, clinical and radiographic examination showed the treatment to be successful.

In this work, breast cancer treatment methods are determined using data mining. For this purpose, software is developed to help to oncology doctor for the suggestion of application of the treatment methods about breast cancer patients. 462 breast cancer patient data, obtained from Ankara Oncology Hospital, are used to determine treatment methods for new patients. This dataset is processed with Weka data mining tool. Classification algorithms are applied one by one for this dataset and results are compared to find proper treatment method. Developed software program called as "Treatment Assistant" uses different algorithms (IB1, Multilayer Perception and Decision Table) to find out which one is giving better result for each attribute to predict and by using Java Net beans interface. Treatment methods are determined for the post surgical operation of breast cancer patients using this developed software tool. At modeling step of data mining process, different Weka algorithms are used for output attributes. For hormonotherapy output IB1, for tamoxifen and radiotherapy outputs Multilayer Perceptron and for the chemotherapy output decision table algorithm shows best accuracy performance compare to each other. In conclusion, this work shows that data mining approach can be a useful tool for medical applications particularly at the treatment decision step. Data mining helps to the doctor to decide in a short time.
Full Text Available Radiotherapy in NPC patients has side effects on the dentition, which affects quality of life dramatically. This case report presents multidisciplinary dental treatment approach in a 17-year-old male patient with a history of nasopharyngeal carcinoma (NPC, which was treated with chemotherapy and radiotherapy. The adolescent patient applied to dental hospital 4 years after the radiotherapy with aesthetic and functional problems on dentition affecting psychological, social, and physical aspects of his life. The dentition of the patient demonstrated the severe destruction as a devastating side effect of radiotherapy. With a successful multidisciplinary approach, our patient’s aesthetics, function, and self-confidence were obtained. Well-established procedures, which include preventative care and maintenance, can reduce the duration and expenses of the treatment and help in challenging the life-long complications of radiotherapy.

Full Text Available Over the past three decades, surgical series of elderly patients treated for pituitary adenomas have been published, all of which used the microscopic transsphenoidal or transcranial approach. The objective of this study was to retrospectively analyze the surgical results of our first 25 elderly patients with non-functioning pituitary macroadenoma (NFPM operated by the endoscopic endonasal approach (EEA. Preoperative visual loss was found in 92.8% of the cases, and 70.8% experienced visual improvement following surgery. Preoperative pituitary dysfunction was found in 69.2% of the cases and postoperative pituitary recovery occurred in 22.2% of them. Mean hospital stay was 6.7 days. The results of this study suggest that surgery remains the first line of treatment for NFPM in the elderly. Because age alone is not a barrier for surgery, patients should be selected for surgical treatment based on their symptoms and clinical condition, as defined by comorbidities.

Phantom limb pain affects between 50 and 80% of amputees. With an increasing number of battle casualties having had an amputation after combat trauma, it is inevitable that both primary and secondary care clinicians will come into contact with a patient with phantom limb pain (PLP). It is widely acknowledged that its complex aetiology means that this condition is often poorly understood and difficult to manage. A growing pathophysiological understanding is shedding new light on the mechanisms which underlie PLP. Knowledge of these mechanisms will inform treatment and enable clinicians to plan and implement solutions which make a difference to those individuals with this condition. This paper seeks to outline current research into this condition and proposes an approach to treatment. This approach has been formulated from an amalgamation of clinical experience working with battle casualties at the Defence Medical Rehabilitation Centre, Headley Court.
Full Text Available New treatment approaches are needed for patients with severe and composite mental disorders who appear resistant to conventional treatments. Such treatment resistant patients often have diagnoses of psychotic or bipolar disorders or severe personality disorders and comorbid conditions. Here we evaluate Basal Exposure Therapy (BET, a novel ward-integrated psychotherapeutic approach for these patients. Central to BET is the conceptualization of undifferentiated existential fear as basic to the patients’ problem, exposure to this fear, and the therapeutic platform Complementary External Regulation (CER which integrates and governs the totality of interventions throughout the treatment process. BET is administered at a locked-door ward with six patient beds and 13.5 full time employees, including a psychiatrist and two psychologists. Thirty-eight patients who had completed BET were included, all but two being female, mean age 29.9 years. Fourteen patients had a diagnosis of schizophrenia or schizoaffective disorder (F20/25, eight had bipolar disorder or recurrent depressive disorder (F31/33, eight had diagnoses in the F40-49 domain (anxiety, stress, dissociation, five were diagnosed with emotionally unstable personality disorder (F60.3, and three patients had other diagnoses. Twenty of the patients (53% had more than one ICD-10 diagnosis. Average treatment time in BET was 13 months, ranging from 2 to 72 months. Time-series data show significant improvements in symptoms and functioning from enrolment to discharge, with effect sizes at 0.76 for the Dissociation Experience Scale, 0.93 for the Brief Symptom Inventory, 1.47 for the Avoidance and Action Questionnaire, and 1.42 and 1.56, respectively for the functioning and symptom subscales of the Global Assessment of Functioning Scale. In addition, the patients used significantly less antiepileptic, antipsychotic, anxiolytic and antidepressant medications at discharge than at treatment enrolment

The modern concept of comprehensive medical rehabilitation of children with complications of osteomyelitis should include an interdisciplinary approach involving orthopedic and maxillofacial surgeons. Early diagnosis in children ensures the timely formation of individualized rehabilitation programs, designed to improve the anatomical and functional characteristics of the affected bones. Along with comprehensive orthopedic treatment, bone-reconstructive surgery of the facial bones of the skull should be focused on restoration of chewing function, external respiration, speech, and facial esthetics.
Full Text Available The moderating role of affective-cognitive consistency in the effects of affectively-based and cognitively-based attitudes on consummatory and instrumental behaviors was explored using two experimental studies in the intergroup context. Study 1 revealed that affectively-based attitudes were better predictors than cognitively-based attitudes regardless of affective-cognitive consistency for consummatory behaviors (e.g., undergraduates' supportive behaviors toward government officials. Study 2, which investigated task groups' supportive behaviors toward an immediate supervisory group, found that for these instrumental behaviors cognitively-based attitudes were better predictors than affectively-based attitudes only when affective-cognitive consistency was high. The present research also examined the mechanism by which affective-cognitive consistency moderates the relative roles of affectively-based and cognitively-based attitudes in attitude-behavior consistency. Results indicated that attitude-behavior consistency is eroded primarily because of the weaker relationship of affective or cognitive components to behaviors than to general attitudes. The reciprocal implications of research on attitudes and work on intergroup relations are considered.

Plunging ranulas arise when a simple ranula extends beyond the floor of the mouth into the neck. Diagnosis is difficult even with modern imaging techniques as they mimic other neck lesions, and traditional treatment involves enucleation of the cyst from the neck. Despite this invasive surgery they tend to recur. We describe a less invasive approach to treatment and review the diagnostic pitfalls. From 2002 to 2011, eight patients presented with a plunging ranula. They were split into two groups: those for whom an incorrect diagnosis was made and those where a less invasive treatment approach was employed. Three patients were misdiagnosed with cervical lymphangioma and had inappropriately invasive surgery. Five patients with established plunging ranulas were treated using an intraoral approach alone, eliminating the need for a cervical incision. Misdiagnosis of a plunging ranula leads to extensive and unnecessary surgery. We propose an algorithm to simplify investigation that employs a low threshold for fine-needle aspiration cytology. The cases presented indicate that these lesions can be managed by a less invasive procedure than currently practised.
Full Text Available Cervical spondylosis is a progressive, chronic and insidious degenerative disease, which origins from the cervical intervertebral disc and then diffuses to surrounding bony and soft tissues. If the spine and nerve roots are involved due to degenerative changes, this is called as cervical spondylotic myeloradiculopathy (CSMR and it is the most frequent cause of myelopathy over age of 50. Cases with progressive character and functional neurological deficits and cases with a prolonged course refractory to conservative therapy shall be treated surgically. The aim of the surgical treatment is to relieve the pressure on the spinal cord and nerve roots, to preserve the proper anatomical alignment of the cervical vertebrae or to reestablish correct anatomical positioning if it is distorted and lastly to increase the life quality by relieving patients neurological signs and complaints. While achieving these goals, complications shall be avoided as much as possible. These goals can be accomplished by anterior or posterior surgical approaches to the cervical vertebrae. The style of the surgical approach can only be decided by a detailed evaluation of the patient's clinical and radiological features. The utmost aim of the surgical procedure, which is to achieve sufficient neurological decompression and to preserve/establish proper cervical vertebral alignment, can be provided best by anterior approaches. In our current study, the criteria to prefer anterior approach in surgical treatment of CSMR will be reviewed. [Cukurova Med J 2014; 39(4.000: 669-678
Full Text Available Laurin J Mack, Bruce D RybarczykClinical Psychology Program, Department of Psychology, Virginia Commonwealth University, Richmond, VA, USAAbstract: Chronic insomnia is a highly prevalent condition that has psychological and medical consequences for those who suffer from it and financial consequences for both the individual and society. In spite of the fact that nonpharmacologic treatment methods have been developed and shown to be as or more effective than medication for chronic insomnia, these methods remain greatly underutilized due to an absence of properly trained therapists and a general failure in dissemination. A stepped-care model implemented in a primary-care setting offers a public health solution to the problem of treatment accessibility and delivery of behavioral treatments for insomnia. Such a model would provide graduated levels of cognitive behavioral intervention, with corresponding increases in intensity and cost, including self-help, manualized group treatment, brief individual treatment, and finally, individualized behavioral treatment provided by a specialist. To provide such a systematic approach, future research would need to confirm several aspects of the model, and a cadre of professionals would need to be trained to administer manualized care in both group and individualized formats.Keywords: cognitive behavioral therapy, chronic insomnia, stepped care, primary care

Full Text Available Effective pharmacological treatments for drug abuse and addiction have not yet been identified. Evidences show that vitamin D may be involved in neurodevelopment and may have a neuroprotective effect on dopaminergic pathways in the adult brain. The fact that vitamin Dincreases the levels of tyrosine hydroxylase expression implies that vitamin D could modulate dopa- minergic processes. Drugs of abuse act through different mechanisms of action and on differentlocations in the brain reward system; however, all of them share a final action in which they increase dopamine levels in the reward pathway. Vitamin D-treated animals showed significant attenuatedmethamphetamine-induced reductions in dopamine and metabolites when compared to control, indicating that vitamin D provides protection for the dopaminergic system against the depleting effects of methamphetamine. In this article, it is speculated that vitamin D would be an effective treatment approach for drug abuse and addiction, if we consider that vitamin D would provide pro-tection for the dopaminergic system against dopamine-depleting effects of drugs, as it did for meth- amphetamine. This hypothesis can provide a new direction towards a new treatment approach fordrug abuse and addiction, as we have no pharmacological treatments at our disposal at the present moment, although several issues need further investigation

The application of antibiotic treatment with assistance of metabolomic approach in axenic isolation of cyanobacterium Nostoc flagelliforme was investigated. Seven antibiotics were tested at 1-100 mg L(-1), and order of tolerance of N. flagelliforme cells was obtained as kanamycin > ampicillin, tetracycline > chloromycetin, gentamicin > spectinomycin > streptomycin. Four antibiotics were selected based on differences in antibiotic sensitivity of N. flagelliforme and associated bacteria, and their effects on N. flagelliforme cells including the changes of metabolic activity with antibiotics and the metabolic recovery after removal were assessed by a metabolomic approach based on gas chromatography-mass spectrometry combined with multivariate analysis. The results showed that antibiotic treatment had affected cell metabolism as antibiotics treated cells were metabolically distinct from control cells, but the metabolic activity would be recovered via eliminating antibiotics and the sequence of metabolic recovery time needed was spectinomycin, gentamicin > ampicillin > kanamycin. The procedures of antibiotic treatment have been accordingly optimized as a consecutive treatment starting with spectinomycin, then gentamicin, ampicillin and lastly kanamycin, and proved to be highly effective in eliminating the bacteria as examined by agar plating method and light microscope examination. Our work presented a strategy to obtain axenic culture of N. flagelliforme and provided a method for evaluating and optimizing cyanobacteria purification process through diagnosing target species cellular state.

The purpose of this study was to evaluate the technical feasibility and clinical efficacy of percutaneous transabdominal treatment of endoleaks after endovascular aneurysm repair. Between 2000 and 2007, six patients with type I (n = 4) or II (n = 2) endoleaks were treated by the percutaneous transabdominal approach using embolization with N-butyl cyanoacrylate with or without coils. Five patients underwent a single session and one patient had two sessions of embolization. The median time between aneurysm repair and endoleak treatment was 25.5 months (range: 0-84 months). Follow-up CT images were evaluated for changes in the size and shape of the aneurysm sac and presence or resolution of endoleaks. The median follow-up after endoleak treatment was 16.4 months (range: 0-37 months). Technical success was achieved in all six patients. Clinical success was achieved in four patients with complete resolution of the endoleak confirmed by follow-up CT. Clinical failure was observed in two patients. One eventually underwent surgical conversion, and the other was lost to follow-up. There were no procedure-related complications. The percutaneous transabdominal approach for the treatment of type I or II endoleaks, after endovascular aneurysm repair, is an alternative method when conventional endovascular methods have failed.

Prostate cancer is a leading cause of cancer death in men in developed countries. Once the tumor has achieved a castration-refractory metastatic stage, treatment options are limited with the average survival of patients ranging from two to three years only. Recently, new drugs for treatment of castration-resistant prostate cancer (CRPC) have been approved, and others are in an advanced stage of clinical testing. In this review we provide an overview of the new therapeutic agents that arrived in the clinical praxis or are tested in clinical studies and their mode of action including hormone synthesis inhibitors, new androgen receptor blockers, bone targeting and antiangiogenic agents, endothelin receptor antagonists, growth factor inhibitors, novel radiotherapeutics and taxanes, and immunotherapeutic approaches. Results and limitations from clinical studies as well as future needs for improvement of CRPC treatments are critically discussed.
Full Text Available Pregnancy associated osteoporosis (PAO is a rare disease characterized by multiple vertebral compression fractures, limitation of movement and severe back pain. A positive family history of PAO, decreased body mass index, sedentary life style, smoking, malnutrition and low calcium intake are among the risk factors of this disease. PAO should be considered in patients with back pain during pregnancy and postpartum period. As a specified therapy option is lack for PAO, discontinuation of lactation and the supplementation of calcium and vitamin D are the main steps of the treatment in patients who are planning to become pregnant in the future. The current data show that bisphosphonates should be avoided and teriparatide may be a treatment option in patients who are planning to become pregnant. In this case report, it was aimed to highlight the diagnosis and treatment approaches of PAO in a patient with back pain during postpartum period.

Lymphedema following treatment for breast cancer can be an irreversible condition with a profound negative impact on quality of life. The lack of consensus regarding standard definitions of clinically significant lymphedema and optimal methods of measurement and quantification are unresolved problems. Inconsistencies persist regarding the appropriate timing of intervention and what forms of treatment should be the standard of care. There are reports that early detection and intervention can prevent progression, however the Level 1 evidence to support this hypothesis has yet to be generated. To assess these controversies, we propose the implementation of a screening program to detect early lymphedema in conjunction with a randomized, prospective trial designed to generate Level 1 evidence regarding the efficacy of early intervention and appropriate treatment strategies. Collaboration among institutions that manage breast cancer patients is essential to establish a standardized approach to lymphedema and to establish guidelines for best practice. PMID:23777977

The widened scope for wastewater treatment plants (WWTP) to consider not only water quality and cost, but also greenhouse gas (GHG) emissions and climate change calls for new tools to evaluate operational strategies/treatment technologies. The IWA Benchmark Simulation Model no. 2 (BSM2) has been......

Overloading of the bioreactors as a result of poor PRIM performance: i) increases the biogenic CO2 emissions from BOD oxidation and biomass decay in the AS section......; ii) increases off-site CO2 emissions due to higher energy demand during the nitrification stage; and, iii) reduces energy recovery from settled organics. The reported results emphasize the importance of a plant-wide approach and the need to consider the interactions between the different treatment...
About half of the patients diagnosed with bipolar disorder (BD) become non-adherent during long-term treatment, a rate largely similar to other chronic illnesses and one that has remained unchanged over the years. Non-adherence in BD is a complex phenomenon determined by a multitude of influences. However, there is considerable uncertainty about the key determinants of non-adherence in BD. Initial research on non-adherence in BD mostly limited itself to examining demographic, clinical and medication-related factors impacting adherence. However, because of inconsistent results and failure of these studies to address the complexities of adherence behaviour, demographic and illness-related factors were alone unable to explain or predict non-adherence in BD. This prompted a shift to a more patient-centred approach of viewing non-adherence. The central element of this approach includes an emphasis on patients' decisions regarding their own treatment based on their personal beliefs, life circumstances and their perceptions of benefits and disadvantages of treatment. Patients' decision-making processes are influenced by the nature of their relationship with clinicians and the health-care system and by people in their immediate environment. The primacy of the patient's perspective on non-adherence is in keeping with the current theoretical models and concordance-based approaches to adherence behaviour in BD. Research over the past two decades has further endorsed the critical role of patients' attitudes and beliefs regarding medications, the importance of a collaborative treatment-alliance, the influence of the family, and the significance of other patient-related factors such as knowledge, stigma, patient satisfaction and access to treatment in determining non-adherence in BD. Though simply moving from an illness-centred to a patient-centred approach is unlikely to solve the problem of non-adherence in BD, such an approach is more likely to lead to a better understanding

Modern external beam radiation therapy treatment delivery processes potentially increase the number of tasks to be performed by therapists and thus opportunities for errors, yet the need to treat a large number of patients daily requires a balanced allocation of time per treatment slot. The goal of this work was to streamline the underlying workflow in such time-interval constrained processes to enhance both execution efficiency and active safety surveillance using a Kaizen approach. A Kaizen project was initiated by mapping the workflow within each treatment slot for 3 Varian TrueBeam linear accelerators. More than 90 steps were identified, and average execution times for each were measured. The time-consuming steps were stratified into a 2 × 2 matrix arranged by potential workflow improvement versus the level of corrective effort required. A work plan was created to launch initiatives with high potential for workflow improvement but modest effort to implement. Time spent on safety surveillance and average durations of treatment slots were used to assess corresponding workflow improvements. Three initiatives were implemented to mitigate unnecessary therapist motion, overprocessing of data, and wait time for data transfer defects, respectively. A fourth initiative was implemented to make the division of labor by treating therapists as well as peer review more explicit. The average duration of treatment slots reduced by 6.7% in the 9 months following implementation of the initiatives (P = .001). A reduction of 21% in duration of treatment slots was observed on 1 of the machines (P Kaizen approach has the potential to improve operational efficiency and safety with quick turnaround in radiation therapy practice by addressing non-value-adding steps characteristic of individual department workflows. Higher effort opportunities are identified to guide continual downstream quality improvements. Copyright © 2017. Published by Elsevier Inc.

Full Text Available This retrospective study compared the functional outcomes among stroke patients who had received rehabilitation based on different physiotherapy treatment approaches. The participants were divided into three groups according to the physiotherapist in charge of their treatment. The primary treatment approaches applied in Group A, Group B, and Group C were the functional approach, the Bobath approach, and the motor learning approach, respectively. For each participant, the Berg's Balance Scale score, the Modified Barthel Index, and the Modified Rivermead Mobility Index were compared among these three groups prior to and after the stroke rehabilitation programme. Within-group analysis showed that Group A, Group B, and Group C participants had a statistically significant improvement in their Modified Barthel Index (p 0.05. In summary, this study showed that different combinations of treatment approaches may induce similar improvement in functional outcomes after stroke rehabilitation.

The 'worst case scenario' (also known as the minimax approach in optimization terms) is a common approach to model the effect of delivery uncertainties in proton treatment planning. Using the 'dose-error-bar distribution' previously reported by our group as an example, we have investigated in more detail one of the underlying assumptions of this method. That is, the dose distributions calculated for a limited number of worst case patient positioning scenarios (i.e. limited number of shifts sampled on a spherical surface) represent the worst dose distributions that can occur during the patient treatment under setup uncertainties. By uniformly sampling patient shifts from anywhere within a spherical error-space, a number of treatment scenarios have been simulated and dose deviations from the nominal dose distribution have been computed. The dose errors from these simulations (comprehensive approach) have then been compared to the dose-error-bar approach previously reported (surface approximation) using both point-by-point and dose- and error-volume-histogram analysis (DVH/EVHs). This comparison has been performed for two different clinical cases treated using intensity modulated proton therapy (IMPT): a skull-base and a spinal-axis tumor. Point-by-point evaluation shows that the surface approximation leads to a correct estimation (95% accuracy) of the potential dose errors for the 96% and 85% of the irradiated voxels, for the two investigated cases respectively. We also found that the voxels for which the surface approximation fails are generally localized close to sharp soft tissue-bone interfaces and air cavities. Moreover, analysis of EVHs and DVHs for the two cases shows that the percentage of voxels of a given volume of interest potentially affected by a certain maximum dose error is correctly estimated using the surface approximation and that this approach also accurately predicts the upper and lower bounds of the DVH curves that can occur under positioning
Full Text Available Objectives. To estimate the prevalence of subjective memory complaints (SMCs in a sample of community-dwelling, older adults and to examine cognitive bases of these complaints. Participants. 499 community-dwelling adults, 65 and older. Measurements. A telephone survey consisting of cognitive tests and clinical and sociodemographic variables. SMCs were based on subjects' evaluations and subjects' perceptions of others' evaluations. Analysis. Logistic regression was used to model the risk for SMCs as a function of the cognitive, clinical, and sociodemographic variables. We tested for interactions of the cognitive variables with age, education, and gender. Results. 27.1% reported memory complaints. Among the younger age, better objective memory performance predicted lower risk for SMCs, while among the older age, better memory had no effect on risk. Among the better-educated people, better global cognitive functioning predicted lower risk for SMCs, while among the less-educated people, better global cognitive functioning had no effect on SMC risk. When predicting others' perceptions, better objective memory was associated with lower risk for SMCs. Conclusion. Objective memory performance and global cognitive functioning are associated with lower risk for SMCs, but these relationships are the strongest for the younger age and those with more education, respectively. Age and education may affect the ability to accurately appraise cognitive functioning.

STAR, a methadone clinic in Portland, Oregon employs a psychoeducational approach in an attempt to provide coherent, comprehensive treatment in meeting diverse client needs. Two hundred and thirty-eight STAR clients completed a 133 item survey as part of an evaluative review of the efficacy of the psychoeducational model. Clients were asked about their perceived treatment needs and expectations, drug use, criminality, mental and physical health, social and economic stability, and their sense of self-worth and life satisfaction. Respondents reported that receiving methadone was the most useful and best liked aspect of treatment, followed by individual counseling, and education and skill classes. Clients indicated low rates of criminal behavior and drug use, but acknowledged high rates of psychological symptoms including depression, anxiety, and irritability, and rated as very important the need to reduce drug use and to improve health, to achieve a sense of life satisfaction, to enhance feelings about self and relationships, especially those with their children. A majority of the respondents had less than adequate income, and a substantial minority had less than a high school education. Longer time in treatment at STAR was associated with reduced heroin and cocaine use and improvements in social, economic and legal realms. The discussion focuses on implications for methadone treatment in general and possible modifications of the STAR program.

Economic research into the design and implementation of policies for the efficient management of water resources has been emphasized by the European Water Framework Directive (Directive 2000/60/EC). The efficient implementation of policies to prevent the degradation and depletion of water resources requires determining their value in social and economic terms and incorporating this information into the decision-making process. A process of wastewater treatment has many associated environmental benefits. However, these benefits are often not calculated because they are not set by the market, due to inadequate property rights, the presence of externalities, and the lack of perfect information. Nevertheless, the valuation of these benefits is necessary to justify a suitable investment policy and a limited number of studies exist on the subject of the economic valuation of environmental benefits. In this paper, we propose a methodology based on the estimation of shadow prices for the pollutants removed in a treatment process. This value represents the environmental benefit (avoided cost) associated with undischarged pollution. This is a pioneering approach to the economic valuation of wastewater treatment. The comparison of these benefits with the internal costs of the treatment process will provide a useful indicator for the feasibility of wastewater treatment projects.

A simple and accurate model of high-temperature treatment of wood can assist in the process design and the evaluation of performance of equipment. The high-temperature treatment of wood is essentially a drying process under linearly-increased gas temperature up to final temperature of 220-230°C which is a challenging process to model. This study is aimed to assess the applicability and accuracy of the reaction engineering approach (REA) to model the heat treatment of wood. In order to describe the process using the REA, the maximum activation energy (ΔE(v,b)) is evaluated according to the corresponding external conditions during the heat treatment. Results indicate that the REA coupled with the heat balance describes both moisture content and temperature profiles during the heat treatment very well. A good agreement towards the experimental data is indicated. It has also been shown that the current model is highly comparable in accuracy with the complex models.
Liver cirrhosis is characterized by distortion of liverarchitecture, necrosis of hepatocytes and regenerativenodules formation leading to cirrhosis. Various typesof cell sources have been used for the managementand treatment of decompensated liver cirrhosis.Knowledge of stem cells has offered a new dimensionfor regenerative therapy and has been considered asone of the potential adjuvant treatment modality inpatients with end stage liver diseases （ESLD）. Humanfetal hepatic progenitor cells are less immunogenic thanadult ones. They are highly propagative and challengingto cryopreservation. In our earlier studies we havedemonstrated that fetuses at 10-18 wk of gestationage contain a large number of actively dividinghepatic stem and progenitor cells which possess bipotentnature having potential to differentiate intobile duct cells and mature hepatocytes. Hepatic stemcell therapy for the treatment of ESLD is in their earlystage of the translation. The emerging technologyof decellularization and recellularization might offera significant platform for developing bioengineeredpersonalized livers to come over the scarcity of desirednumber of donor organs for the treatment of ESLD.Despite these significant advancements long-termtracking of stem cells in human is the most importantsubject nowadays in order to answer several unsettlesissues regarding the route of delivery, the choiceof stem cell type（s）, the cell number and the timepointof cell delivery for the treatment in a chronicsetting. Answering to these questions will furthercontribute to the development of safer, noninvasive,and repeatable imaging modalities that could discoverbetter cell therapeutic approaches from bench to bedside.Combinatorial approach of decellularization andnanotechnology could pave a way towards the betterunderstanding in determination of cell fate posttransplantation.

Whether it is chronic myeloid leukemia, ALK-expressing malignancies, or HER2-positive breast cancer, targeted-therapies for treatment of human cancers have shown great promise. However, as they hit a single molecule expressed in neoplastic cells, their use is frequently associated with development of resistance. In cancer cells many signaling pathways operate in parallel, hence the idea of multi-targeted therapy is prevailing. The Society of Translational Cancer Research held its biennial meeting in the capital city of India, Delhi from February 6th through 9th, 2014 to discuss 'Multi-targeted Approach to Treatment of Cancer'. Over 200 scientists, clinicians, trainees, and industry representatives from different countries gathered in Vigyan Bhavan, the hotspot of Delhi for four days to talk and discuss on a variety of topics related to multi-targeted therapeutic approaches. Talks were presented by leaders in the cancer research field from various countries. It became clear from this conference that coupling multiple targeted-agents or using an agent that hits an individual target in several independent locations in the disease-causing pathway(s) may be the best approach to treat different cancers.

Full Text Available This trial was undertaken to examine 3 patients aged 7 months to 13 years with esthesioneuroblastoma were examined to evaluate the possibilities and efficiency of an endoscopic endonasal approach in its surgical treatment in pediatric practice. Additional orientation was provided by a Vector Vision Compact system (Brain Lab, USA. The trial has established that the endoscopic endonasal approach to creating an isolated transnasal and combined transnasal/transethmoidal corridor and a transcribriform approach is highly effective and reasonably safe for the treatment of children with esthesioneuroblastoma: no intra- and postoperative complications were recorded in the trial; analysis of the immediate results of surgical interventions has shown a clinical regression in all the patients. Fatal outcomes and recurrent tumor were absent in the late (1–5-year period. The additional employment of the navigation equipment allowed one to more accurately use surgical tools in the narrow anatomic spaces and to more thoroughly affect an abnormality, which was eventually shown in more conservative surgery.
Full Text Available Introduction: Rectal prolapse is a disease, which is an important cause of social and functional problems and has a continuing debate about the ideal surgical treatment of itself. In this study, we aimed to investigate the abdominal and perineal approaches with early and late postoperative result in the patients undergoing surgery for rectal prolapse.Materials and methods: Between 2006-2011, the records of 21 patients undergoing surgery with the diagnosis of rectal prolapse were reviewed, retrospectively. The demographic and physical examination findings, surgical procedures, early and late postoperative complications, recurrence and mortality rates were recorded.Results: The median age was 43 years and female/male ratio was 1.63/1. The most common presenting complaint was gas control failure and often wetting with mucus. Stage 1 and stage 3 rectal prolapses was detected in 19% and 81% of the patients, respectively. The most common surgical procedure was Notaras (54%. Early postoperative complications were seen in 14.3% of the patients. There were no postoperative recurrence, mortality and complication requiring re-exploration. Advanced age and shorter duration of hospital stay were determined and often performed under regional anesthesia in the patients undergoing perineal approach. No statistical differences were observed in terms of early postoperative complications and recurrence.Conclusion: Results of abdominal and perineal approaches were similar, when they were applied with taking into account the risk factors for surgical treatment, findings of the patients and the surgeon’s experience.

Changes in serum tumor biomarkers may indicate treatment efficacy. Traditional tumor markers may soon be replaced by novel serum biomarkers, such as circulating tumor cells (CTCs) or circulating tumor nucleic acids. Given their promising predictive values, studies of their kinetics are warranted. Many methodologies meant to assess kinetics of traditional marker kinetics during anticancer treatment have been reported. Here, we review the methodologies, the advantages and the limitations of the analytical approaches reported in the literature. Strategies based on a single time point were first used (baseline value, normalization, nadir, threshold at a time t), followed by approaches based on two or more time points [half-life (HL), percentage decrease, time-to-events…]. Heterogeneities in methodologies and lack of consideration of inter- and intra-individual variability may account for the inconsistencies and the poor utility in routine. More recently, strategies based on a population kinetics approach and mathematical modeling have been reported. The identification of equations describing individual kinetic profiles of biomarkers may be an alternative strategy despite its complexity and higher number of necessary measurements. Validation studies are required. Efforts should be made to standardize biomarker kinetic analysis methodologies to ensure the optimized development of novel serum biomarkers and avoid the pitfalls of traditional markers.

This review article analyzes, through a nonsystematic approach, the pathophysiology of acute pancreatitis (AP) with a focus on the effects of thoracic epidural analgesia (TEA) on the disease. The benefit-risk balance is also discussed. AP has an overall mortality of 1 %, increasing to 30 % in its severe form. The systemic inflammation induces a strong activation of the sympathetic system, with a decrease in the blood flow supply to the gastrointestinal system that can lead to the development of pancreatic necrosis. The current treatment for severe AP is symptomatic and tries to correct the systemic inflammatory response syndrome or the multiorgan dysfunction. Besides the removal of gallstones in biliary pancreatitis, no satisfactory causal treatment exists. TEA is widely used, mainly for its analgesic effect. TEA also induces a targeted sympathectomy in the anesthetized region, which results in splanchnic vasodilatation and an improvement in local microcirculation. Increasing evidence shows benefits of TEA in animal AP: improved splanchnic and pancreatic perfusion, improved pancreatic microcirculation, reduced liver damage, and significantly reduced mortality. Until now, only few clinical studies have been performed on the use of TEA during AP with few available data regarding the effect of TEA on the splanchnic perfusion. Increasing evidence suggests that TEA is a safe procedure and could appear as a new treatment approach for human AP, based on the significant benefits observed in animal studies and safety of use for human. Further clinical studies are required to confirm the clinical benefits observed in animal studies.

There is currently no standardised approach to arteriovenous malformation (AVM) reporting. Existing AVM classification systems focuses on angioarchitectural features and omit haemodynamic, anatomical and topological parameters intuitively used by therapists. We introduce a symbolic vocabulary to represent the state of an AVM of the brain at different stages of treatment. The vocabulary encompasses the main anatomic and haemodynamic features of interest in treatment planning and provides shorthand symbols to represent the interventions themselves in a schematic representation. The method was presented to 50 neuroradiologists from14 countries during a workshop and graded 7.34 ± 1.92 out of ten for its usefulness as means of standardising and facilitating communication between clinicians and allowing comparisons between AVM cases. Feedback from the survey was used to revise the method and improve its completeness. For an AVM test case, participants were asked to produce a conventional written report and subsequently a diagrammatic report. The two required, on average, 6.19 ± 2.05 and 5.09 ± 3.01 min, respectively. Eighteen participants said that producing the diagram changed the way they thought about the AVM test case. Introduced into routine practice, the diagrams would represent a step towards a standardised approach to AVM reporting with consequent benefits for comparative analysis and communication as well as for identifying best treatment strategies.

One of the main neuropathological lesions observed in brain autopsy of Alzheimer's disease (AD) patients is the extracellular senile plaques mainly composed of amyloid-beta (Aβ) peptide. Recently, treatment strategies have focused on modifying the formation, clearance, and accumulation of this potentially neurotoxic peptide. β- and γ-secretase are responsible for the cleavage of amyloid precursor protein (APP) and the generation of Aβ peptide. Treatments targeting these two critical secretases may therefore reduce Aβ peptide levels and positive impact on AD. Vaccination is also an advanced approach against Aβ. This review focuses on recent advances of our understanding of this key peptide, with emphasis on Aβ peptide synthesis, accumulation and neurotoxicity, and current therapies including vaccination and two critical secretase inhibitors. MicroRNAs (miRNAs) are a class of conserved endogenous small noncoding RNAs, known to regulate the expression of complementary messenger RNAs, involved in AD development. We therefore address the relationship of miRNAs in the brain and Aβ generation, as a novel therapeutic approach to the treatment of AD while also providing new insights on the etiology of this neurological disorder.

Background: Anterior cruciate ligament reconstruction (ACLR) has been established as the gold standard for treatment of complete ruptures of the anterior cruciate ligament (ACL) in active, symptomatic individuals. In contrast, treatment of partial tears of the ACL remains controversial. Biologically augmented ACL-repair techniques are expanding in an attempt to regenerate and improve healing and outcomes of both the native ACL and the reconstructed graft tissue. Purpose: To review the biologic treatment options for partial tears of the ACL. Study Design: Review. Methods: A literature review was performed that included searches of PubMed, Medline, and Cochrane databases using the following keywords: partial tear of the ACL, ACL repair, bone marrow concentrate, growth factors/healing enhancement, platelet-rich plasma (PRP), stem cell therapy. Results: The use of novel biologic ACL repair techniques, including growth factors, PRP, stem cells, and bioscaffolds, have been reported to result in promising preclinical and short-term clinical outcomes. Conclusion: The potential benefits of these biological augmentation approaches for partial ACL tears are improved healing, better proprioception, and a faster return to sport and activities of daily living when compared with standard reconstruction procedures. However, long-term studies with larger cohorts of patients and with technique validation are necessary to assess the real effect of these approaches.

The clinician faces treatment planning challenges when patients present with generalized severe chronic periodontitis that may result in tooth loss. This article provides a treatment planning discussion along with approaches for treating such patients. It presents the clinical question: What is the best means for approaching treatment planning in a patient with severe periodontitis requiring extraction and replacement of some teeth? Two treatment approaches are discussed—a reconstructive approach versus an adaptive one—both of which have an end goal of achieving periodontal health and occlusal stability, and each has its own advantages and disadvantages. In conclusion, utilizing a global prognostic approach will assist clinicians anticipate the eventual restorative needs of patients and prescribe customized periodontal and restorative therapies that best address those needs.

The sample preparation of samples containing bovine serum albumin (BSA), e.g., as used in transdermal Franz diffusion cell (FDC) solutions, was evaluated using an analytical quality-by-design (QbD) approach. Traditional precipitation of BSA by adding an equal volume of organic solvent, often successfully used with conventional HPLC-PDA, was found insufficiently robust when novel fused-core HPLC and/or UPLC-MS methods were used. In this study, three factors (acetonitrile (%), formic acid (%) and boiling time (min)) were included in the experimental design to determine an optimal and more suitable sample treatment of BSA-containing FDC solutions. Using a QbD and Derringer desirability (D) approach, combining BSA loss, dilution factor and variability, we constructed an optimal working space with the edge of failure defined as Do0.9. The design space is modelled and is confirmed to have an ACN range of 8373%and FA content of 170.25%.

In this article, we describe how cognitive hypnotherapy can be used in conjunction with evidence-based practices for the treatment of post-traumatic stress disorder (PTSD). We review cognitive-behavioral interventions for PTSD, including mindfulness and acceptance-based approaches, and contend that (a) empirical support for the use of hypnosis in treating a variety of conditions is considerable; (b) hypnosis is fundamentally a cognitive-behavioral intervention; (c) psychological interventions with a firm footing in cognitive-behavioral therapy (CBT) are well-suited to treat the symptoms of PTSD; and (d) hypnosis can be a useful adjunct to evidence-based cognitive-behavioral approaches, including mindfulness and acceptance-based interventions, for treating PTSD.

We propose a self-consistant approach to the treatment of nuclear matter as a crystal of solitons in the Wigner-Seitz approximation. Specifically, we use a Bloch-like boundary condition on the quarks at the edge of a spherical cell which allows the dispersion relation for a given radius to be calculated self-consistently along with the meson fields; in previous work some ansatz for the dispersion relation has always been an input. Results in all models are very sensitive to the form of the dispersion relation, so our approach represents a significant advance. We apply the method to both the Friedberg Lee model and the chiral quark-meson model of Birse and Banerjee. Only the latter shows short range repulsion; in the former the transition to a quark plasma occurs at unrealistically low densities.

Of all developments in dental technology, fulfilling the esthetic and functional demands of the patient, especially regarding anterior reconstructions, is still a challenge for both dentists and dental technicians. This becomes more difficult for patients with a previous treatment history that is not ideal. This case presentation demonstrates reconstruction of an anterior zirconia resin-bonded fixed dental prosthesis (RBFDP) for the mandible with a combined approach utilizing veneers for harmonized space distribution on the abutment teeth and an implant-supported zirconia fixed dental prosthesis in the anterior segment of the maxilla. Adhesive cementation of the restorations is also presented in a step-by-step approach based on the current state of the art.

The approach is widely accepted by experts in emergency medicine and likely improves outcomes by helping health care professionals focusing on the most life-threatening clinical problems. In an acute setting, high-quality ABCDE skills among all treating team members can save valuable time and improve team performance. Dissemination of knowledge and skills related to the ABCDE approach are therefore needed. This paper offers a practical “how-to” description of the ABCDE approach.Keywords: emergency medicine, general medicine, internal medicine, multiple trauma, multiple injury

Methods Review clinical data of 18 cases with anterior circulation mirror aneurysms who underwent one-stage clipping via bilateral frontolateral approaches from July 2010 to July 2015 admitted to Department of Neurosurgery in Tianjin Huanhu Hospital. The operative efficacy was evaluated according to postoperative Glasgow Outcome Scale (GOS. Results The 36 aneurysms in 18 patients were successfully clipped via bilateral frontolateral approaches at one-stage, including 18 posterior communicating artery (PCoA mirror aneurysms in 9 cases and 18 middle cerebral artery (MCA mirror aneurysms in 9 cases. GOS score of 5 was discovered in 16 cases, and 4 was discovered in 2 cases after operation. One case underwent ventriculoperitoneal shunting (VPS due to communicating hydrocephalus, one case got postoperative pulmonary infection and no death occurred. Intracranial CTA at 6 months postoperatively showed aneurysms of 18 patients were clipped completely, the parent artery blood flow was smooth, and no recurrence was found. Conclusions Microsurgical one-stage clipping via bilateral frontolateral approaches for treating intracranial mirror aneurysms is a sugrical method with small incision, fitting surgical field, high safety, satisfactory effect and good prognosis, which is a new minimally invasive neurosurgical technique.

Full Text Available The interference caused by autism in the areas of occupation of an individual is extremely significant and it occurs mainly because of behaviors related to deficits in emotional, cognitive, motor, sensory and social interaction skills. In children, such behaviors are evident especially through play and the fixation on objects, and difficulty in symbolic-abstract thinking and sharing jokes, that is, a poor and stereotyped play, featuring a developmental delay. In order to stimulate and develop skills of autistic children and their social participation in typical pattern, Occupational Therapy uses different models and approaches to achieve its goals. This study aimed to describe the basic principles of a promising model - DIR (Developmental, Individual-difference, Relationship-based, and its main approach - the Floortime, to discuss its effectiveness when used from the perspective of Occupational Therapy in the treatment of autistic children. We carried out a literature search on this approach and found that it is characterized by a series of creative and spontaneous interactions that occur on the floor, which encourages the initiative of children and their intentional behavior, trying to promote the fundamental skills to the highest level possible that the child can reach through play. The present findings indicate the effectiveness of Floortime in previous studies with autistic children and several common points between the principles of the approach and those of Occupational Therapy, confirming the possibility of Floortime use by occupational therapists in the care for this population.

Implicit in the growing interest in patient-centered outcomes research is a growing need for better evidence regarding how responses to a given intervention or treatment may vary across patients, referred to as heterogeneity of treatment effect (HTE). A variety of methods are available for exploring HTE, each associated with unique strengths and limitations. This paper reviews a selected set of methodological approaches to understanding HTE, focusing largely but not exclusively on their uses with randomized trial data. It is oriented for the "intermediate" outcomes researcher, who may already be familiar with some methods, but would value a systematic overview of both more and less familiar methods with attention to when and why they may be used. Drawing from the biomedical, statistical, epidemiological and econometrics literature, we describe the steps involved in choosing an HTE approach, focusing on whether the intent of the analysis is for exploratory, initial testing, or confirmatory testing purposes. We also map HTE methodological approaches to data considerations as well as the strengths and limitations of each approach. Methods reviewed include formal subgroup analysis, meta-analysis and meta-regression, various types of predictive risk modeling including classification and regression tree analysis, series of n-of-1 trials, latent growth and growth mixture models, quantile regression, and selected non-parametric methods. In addition to an overview of each HTE method, examples and references are provided for further reading.By guiding the selection of the methods and analysis, this review is meant to better enable outcomes researchers to understand and explore aspects of HTE in the context of patient-centered outcomes research.

Full Text Available Gliomas are the most common primary central nervous system tumors with a dismal prognosis. Despite recent advances in surgery, radiotherapy, and chemotherapy, current treatment regimens have a modest survival benefit. A crucial challenge is to deliver drugs effectively to invasive glioma cells residing in a sanctuary within the central nervous system. New therapies are essential, and oligonucleotide-based approaches, including antisense, microRNAs, small interfering RNAs, and nucleic acid aptamers, may provide a viable strategy. Thanks to their unique characteristics (low size, good affinity for the target, no immunogenicity, chemical structures that can be easily modified to improve their in vivo applications, these molecules may represent a valid alternative to antibodies particularly to overcome challenges presented by the blood-brain barrier. Here we will discuss recent results on the use of oligonucleotides that will hopefully provide new effective treatment for gliomas.
Full Text Available Orthodontic treatment in adult patients is one of the most frequently encountered components involving multidisciplinary approaches. In the present report, a 28-year-old male patient was treated for localized chronic periodontitis with pocket formation, mobility, pathologic migration and malalignment of maxillary left lateral incisor tooth #22. The periodontal therapy included motivation, education and oral-hygiene instructions (O.H.I., scaling and root planing and periodontal flap surgery. Subsequently on resolution of periodontal inflammation, orthodontic therapy was carried out using the orthodontic aligner for a period of 6 months. Post-treatment (3 years results showed complete resolution of infrabony pocket with significant bone fill, reduced tooth mobility and complete alignment of the affected maxillary left lateral incisor, thus restoring the esthetics and function.
Full Text Available Introduction: We can define extracranial carotid artery aneurysm (ECAA as bulb dilatation greater than 200% of the diameter of the internal carotid artery (ICA or in a case of common carotid artery (CCA greater than 150% of the diameter. Surgical intervention is required for the treatment of this disease.Case report: This study presents an open vascular surgical procedure to resolve ECAA. We report a case of 61 years old woman with an extracranial internal carotid artery berry aneurysm, presented with a headache and dizziness when turning the head aside. Classic open surgery was performed and the lumen of berry aneurysm was separated with three clips from the lumen of ICA.Conclusions: The open surgical approach is the method of choice for the treatment of extracranial internal carotid artery pathological conditions.

Schizophrenia for many patients is a lifelong mental disorder with significant consequences on most functional domains. One fifth to one third of patients with schizophrenia experience persistent psychotic symptoms despite adequate trials of antipsychotic treatment, and are considered to have treatment-resistant schizophrenia (TRS). Clozapine is the only medication to demonstrate efficacy for psychotic symptoms in such patients. However, clozapine is not effective in 40%-70% of patients with TRS and it has significant limitations in terms of potentially life-threatening side effects and the associated monitoring. Accordingly, a number of pharmacological and non-pharmacological biological approaches for clozapine-resistant TRS have emerged. This article provides a brief updated critical review of recent therapeutic strategies for TRS, particularly for clozapine-resistant TRS, which include pharmacotherapy, electroconvulsive therapy, repetitive transcranial magnetic stimulation, and transcranial direct current stimulation.

The pathogenesis of psoriatic arthritis (PsA) is still under discussion but great advances have been made in the last 2 decades that confirm the central role of tumor necrosis factor-α (TNF-α) in its inflammatory milieu. New therapeutic approaches have been proposed, and new molecules with anti-TNF-α activity have been chemically altered to improve their pharmacological properties. Certolizumab pegol (CZP) is a PEGylated Fc-free anti-TNF that has been shown clinically to be effective in the treatment of rheumatoid arthritis (RA), skin psoriasis, and PsA. This article summarizes available data on its clinical efficacy and safety profile in the treatment of patients with PsA.

Full Text Available The limited sensitivity of the historical treatment response criteria for acute myeloid leukemia (AML has resulted in a different paradigm for treatment compared with most other cancers presenting with widely disseminated disease. Initial cytotoxic induction chemotherapy is often able to reduce tumor burden to a level sufficient to meet the current criteria for “complete” remission. Nevertheless, most AML patients ultimately die from their disease, most commonly as clinically evident relapsed AML. Despite a variety of available salvage therapy options, prognosis in patients with relapsed or refractory AML is generally poor. In this review, we outline the commonly utilized salvage cytotoxic therapy interventions and then highlight novel investigational efforts currently in clinical trials using both pathway-targeted agents and immunotherapy based approaches. We conclude that there is no current standard of care for adult relapsed or refractory AML other than offering referral to an appropriate clinical trial.

Vitiligo is a common inflammatory skin disease with a worldwide prevalence of 0.5% to 2.0% of the population. In the pediatric population, the exact prevalence of vitiligo is unknown, although many studies state that most cases of vitiligo are acquired early in life. The disease is disfiguring, with a major psychological impact on children and their parents. Half of vitiligo cases have a childhood onset, needing thus a treatment approach that will minimize treatment side effects while avoiding psychological impacts. Management of vitiligo should take into account several factors, including extension, psychological impact, and possible associations with other autoimmune diseases. This review discusses the epidemiology of vitiligo and outlines the various clinical presentations associated with the disorder and their differential diagnosis. In addition, the pathophysiology and genetic determinants, the psychological impact of vitiligo, and management strategies are reviewed.

A 3D, unsteady-state mathematical model was used to simulate the behaviour of wood during high temperature treatment. The model is based on Luikov's approach and solves a set of coupled heat and mass transfer equations. Using the model, the temperature and moisture content profiles of wood were predicted as a function of time for different heating rates. Parallel to the modelling study, an experimental study was carried out using small birch samples. The samples were subjected to high temperature treatment in a thermogravimetric system under different operating conditions. The experimental results and the model predictions were found to be in good agreement. The results show that the distributions of temperature and moisture content are influenced appreciably by the heating rate and the initial moisture content. (author)

The use of an extracorporeal treatment (ECTR) in a poisoned patient may be life-saving in a limited number of scenarios. The decision-processes surrounding the use of ECTR in poisoning is complex: most nephrologists are not trained to assess a poisoned patient while clinical toxicologists rarely prescribe ECTRs. Deciding on which ECTR is most appropriate for a poison requires a good understanding of the poison's physicochemical and pharmacokinetic properties. Further, a detailed understanding of the capabilities and limitations of the different ECTRs can be useful to select the most appropriate ECTR for a given clinical situation. This manuscript provides a stepwise approach to assess the usefulness of ECTRs in poisoning.

The treatment of Borderline Personality Disorder has been a challenge for Cognitive Therapy (CT): some modifications to the CT basic model had to be implemented in order to intervene with BPD patients. Young's schema-focused approach offers an intervention model which relies on early maladaptive schemas and modes concepts. According to this model, the BDP presents four dysfunctional modes: the Abandoned Child mode, the Detached Protector mode, the Punitive Parent mode, the Angry Child mode. The therapist must identify the presence of these modes and implement therapeutic strategies specific to each of them. There are four different kinds of therapeutic strategies: interpersonal (therapy relationship), experiential, cognitive and behavioral.

WWTPs fail to perform proper treatment due to their being worn-out and obsolete. However a tougher legislation accelerates their reconstruction. Approaches to the WWTP reconstruction should demonstrate a strong economic and technological base. The author proposes a new algorithm for their reconstruction. A sensible combination of the principles of WWTP restructuring, development of new fine wastewater cleaning methods, and assimilation of new materials and chemical agents will help resolve the vital problem of waste water discharge into Russia's water bodies. This is the first methodology of reconstruction of WWTPs developed on the basis of the above concept and supported by practical implementation.

This addendum to "Novel application of bacteriophage for controlling foaming in wastewater treatment plant- an eco-friendly approach " includes characteristics of the phages NOC1, NOC2 and NOC3 not discussed in the previous paper. The phage adsorption and host interaction properties, their sensitivity to pH and temperature are inferred. NOC2 is seen to be more temperature resistant while others are not. All the phages show pH sensitivity. There is a variance observed in the behavior of these phages. Also, applicability of the phage based system to large scale reactors is studied and discussed here.
Full Text Available Primitive neuroectodermal tumor is a small round cell malignancy which rarely involves the orbit. We report a case of a two-year old male child presenting as unilateral eccentric proptosis with extraconal and intraconal mass, diagnosed as primary peripheral primitive neuroectodermal tumor (pPPNET on histopathology and immunohistochemistry. There is no defined consensus in the management of these tumors due to its rare presentation. We describe its distinguishing features with emphasis on multimodal and aggressive treatment approach which ensures appropriate management of these cases.

Full Text Available Results of treatment of 134 patients with stage I ovarian cancer were analyzed, 48 of these patients underwent laparoscopic surgery. From a technical point of view, concerning duration of the surgery, blood loss, lack of both intra- and postoperative complications, shorter periods of patient rehabilitation, laparoscopic approach can be regarded as the most preferred. However, when comparing the timing of relapse-free survival there was a trend towards its reduction after laparoscopic surgery compared with an open surgery, causing a widespread use of this technique even in the initial stages of ovarian cancer.
Full Text Available Recent histological studies of thrombi retrieved from patients with an acute ischemic stroke using the endovascular thrombectomy devices and correlation with early vessel computed tomography (CT and magnetic resonance imaging (MRI characteristics have given relevant insights into the pathophysiology of thrombotic lesions and may facilitate the development of improved reperfusion treatment approaches. We present a review of recent studies on the histopathologic analysis of thrombi, studies of MRI, and CT imaging correlation with thrombus histology, and detailed structural analysis of thromboemboli retrieved by thrombectomy devices during an acute ischemic stroke.
Full Text Available A 7-year-old Brahman cow was diagnosed as suffering from chronic foetal mummification of unknown aetiology, concurrent cystic ovarian disease, prolapse of the 2nd cervical ring and chronic cervicitis. Repeated treatment with prostaglandin F2a and oestrogen failed to resolve the mummification. A hysterotomy was performed via an incision in the dorsolateral vaginal wall. Good exposure of the uterine horn was achieved and mild post-operative complications were observed. Colpotomy can be regarded as an alternative surgical approach to the moderately enlarged bovine uterus.

Introduction Despite improved research in the treatment, depression remains difficult to treat. Till date, successful treatment of depression using taping therapy has not been known yet. We report cases where patients with severe depressive symptoms were successfully treated by taping therapy, a new approach. Methods In case 1, a patient was taking several psychiatric medications for 10 years and admitted often to the psychiatric hospital with a leaning head, flexible legs, and nearly closed eyes; in case 2, a patient after a hysterectomy complained with heart palpitations, depressive- and anxiety-like behaviors, insomnia, and gastrointestinal problems; and in case 3, a patient with complaints of adverse effects from antidepressant medications had suicidal thoughts frequently. The medical tapes were placed on acupoints, trigger points, and pain points found by finger pressing examination in the chest, sides, and upper back of the patients. Results In case 1, the patient started weeping immediately after the first treatment. He discontinued psychiatric drugs and returned to baseline functioning after 2 months. In case 2, the patient felt at ease showing decreased palpitation immediately after the first treatment, and after 1 week, she quit medications. In case 3, the patient experienced a sense of calmness following the first treatment and recovered from her symptoms after 2 weeks. Conclusion These results suggest the following key points: examination of acupoints and trigger points of chest, sides, and upper back is useful in the assessment of depression; regulating bioelectric currents on these points is helpful in the treatment of depression; and depression can be treated successfully with taping therapy.

Full Text Available Objective: We aimed to demonstrate the approaches of physicians with a questionnaire toward the patients with pulmonary thromboembolism (PTE in our country. Methods: An invitation letter including a questionnaire with 28 questions to assess the approaches they prefer in the patients with PTE and the capabilities of the departments they work at and a link for the questionnaire was directed to the mail groups of chest diseases specialists. Responses of the physicians who participated in the questionnaire were reviewed. Results: The examinations used to diagnose PTE such as D-dimer, troponin, echocardiographic Doppler ultrasonography and multidetector computed tomography (CT have been performed in 94% of the institutions, ventilation/perfusion scintigraphy, MRI and pulmonary angiography examinations were performed in 50% of the instututions. While D-dimer test was performed in 73.2% of the institutions by quantitative ELISA; in 15.7% of them it was semiquantitative and in 11.6% of the instutitions it was performed by latex agglutination. 81% of physicians were seen to be using clinical probability scoring systems and most commonly used scoring method was seen to be Wells scoring with a rate of 90%. According to the simplified PESI score, 61.5% of the physicians reported to prefer outpatient treatment. In non-massive and submassive pulmonary thromboemboli patients, 86.2% of the physicians reported to prefer thr low molecular weight heparin (LMWH treatment; vitamin K antagonist in maintenance treatment was also the most commonly resorted drug with a percentage of 84.9. Conclusion: The absence of the examinations used in the diagnosis and treatment of PTE in most institutions and difficulty to reach the available examinations at all hours of the day were significant facts. Especially; lack of access to high-sensitivity D-dimer test, bedside echocardiography used to assess right ventricular dysfunction, troponin and NT-proBNP makes us think about low

India is a large user of groundwater resources and one of the countries most impacted by fluoride; the rural areas, where 90% of drinking water is sourced from fluoride-contaminated groundwater, are particularly vulnerable. Since fluorosis has no cure, prevention is key, and defluoridation treatment is a primary mitigation approach. Despite the successful development of defluoridation treatments and technologies worldwide, these solutions encounter a range of operational barriers (e.g. lack of economic and chemical resources, scarcity of skilled operators) and uptake is hindered by a lack of user understanding and participation in the development of community treatment options. Preliminary research highlights that plants typically fail after the first three years of installation, we are investigating why and how to overcome this barrier. Monitoring fluoride concentrations, operations, and user attitudes at several defluoridation plants in Maharashtra, we assess the overall success of these installed technologies. The research considers: (1) the fluctuations in source concentrations with respect to climate and changing water use patterns, (2) treatment with regards to performance, operation, and maintenance of implemented technologies to meet fluoride standards, and (3) user understanding, acceptability and uptake of defluoridation technology. This presentation highlights the operational and behavioral barriers to sustainable defluoridation in India.

To investigate the neural and cognitive bases of upper limb apraxia in corticobasal degeneration (CBD). Eighteen patients with CBD underwent a cognitive neuropsychological assessment of apraxia and resting [(18)F]-fluorodeoxyglucose PET scanning. Two complementary measures of apraxia were computed for each modality of gesture production. First, a performance score measured error frequency during gesture execution. Second, as a more stringent test of the integrity of the praxis system, the correction score measured the patient's ability to correct his or her errors on a second attempt. For each measure type, a cut-off score for the presence of apraxia was defined with regard to healthy controls. Using each cut-off score, the regional cerebral glucose metabolism of patients with CBD with apraxia (i.e., performing below cut-off score) was compared with that of patients with CBD without apraxia. Mean performance scores were below normal values in all modalities. Anterior cingulate hypometabolism predominated in patients with CBD who performed below the cut-off performance score. At variance, mean correction scores were below normal values for gesture imitation only. Hypometabolism in superior parietal lobule and supplementary motor area characterized patients with CBD who were unable to correct their errors at the same rate as control subjects did. Distinct neural networks underlie distinct aspects of the upper limb apraxic deficits in CBD. Extending previous findings of gesture production deficits in CBD, the use of complementary measures of apraxic behavior discloses a visuoimitative upper limb apraxia in CBD, underlain by a metabolic decrease in a parietofrontal neural network.
Full Text Available Background: Ideal surgical treatment for thoracic disc herniation (TDH is controversial due to variations in patient presentation, pathology, and possible surgical approach. Althougth discectomy may lead to improvements in neurologic function, it can be complicated by approach related morbidity. Various posterior surgical approaches have been developed to treate TDH, but the gold standard remains transthoracic decompression. Certain patients have comorbidities and herniation that are not optimally treated with an anterior approach. A transfacet pedicle approach was first described in 1995, but outcomes and complications have not been well described. The aim of this work was to evaluate the clinical effect and complications in a consecutive series of patients with symptomatic thoracic disc herniations undergoing thoracic discectomy using a modified transfacet approach. Materials and Methods: 33 patients with thoracic disc herniation were included in this study. Duration of the disease was from 12 days to 36 months, with less than 1 month in 13 patients. Of these, 15 patients were diagnosed with simple thoracic disc herniation, 6 were associated with ossified posterior longitudinal ligament, and 12 with ossified or hypertrophied yellow ligament. A total of 45 discs were involved. All the herniated discs and the ossified posterior longitudinal ligaments were excised using a modified transfacet approach. Laminectomy and replantation were performed for patients with ossified or hypertrophied yellow ligament. The screw-rod system was used on both sides in 14 patients and on one side in l9 patients. Results: 29 patients were followed up for an average of 37 months (range 12-63 months and 4 patients were lost to followup. Evaluation was based on Epstein and Schwall criteria.5 15 were classified as excellent and 10 as good, accounting for 86.21% (25/29; 2 patients were classified as improved and 2 as poor. All the patients recovered neurologically after

Neurosurgical textbooks describe an infrainguinal approach as the standard or preferred option for the surgical treatment of meralgia paresthetica (MP), the most frequent entrapment neuropathy of the lower limb. However, inhomogeneous results led the authors to adopt a suprainguinal, retroperitoneal approach for decompression of the lateral femoral cutaneous nerve. In this paper the authors' aim was to study the outcome of patients harboring MP treated via this different surgical approach. The outcome of 55 consecutive patients who underwent surgery for MP via the suprainguinal retroperitoneal approach during a 15-year period was ascertained through postal questionnaires (in 47 patients) and follow-up visits (in 8 patients). The male to female ratio was 1:0.67, and the mean patient age was 50 +/- 12.9 years. The mean follow-up was 3.2 +/- 3.3 years. Seven of the patients underwent bilateral surgery. Intraoperatively the lateral femoral cutaneous nerve was consistently found in close anatomical relationship to the anterior superior iliac spine, although some variations regarding the diameter, number of branches, and underlying pathological entity were observed. Eighty-seven percent of patients showed improvement (21 patients) or complete remission (27 patients) of painful dysesthesia in the anterolateral thigh, and 13% (7 patients) remained unchanged. In addition 82% had improvement (31 patients) or complete remission (14 patients) of hypesthesia, leaving 18% with unchanged (9 patients) or worsened (1 patient) hypesthesia. In the patient-evaluated group 66% (31 of 47) were completely satisfied with the outcome, 23% (11 of 47) were partially satisfied, and 11% (5 of 47) were not satisfied with the outcome. Two cases each of recurrence, seroma, wound infection, and 1 case of hematoma requiring revision were encountered as complications. The suprainguinal retroperitoneal approach is a viable first-choice option for the surgical relief of MP.

This review examined the diagnostic approach, surgical treatment, and outcomes of cervical sympathetic chain schwannomas (CSCS) to guide clinical decision making. Medline, EMBASE, and Cochrane databases. A literature review from 1998 to 2013 identified 156 articles of which 51 representing 89 CSCS cases were evaluated in detail. Demographic, clinical, and outcomes data were extracted by 2 independent reviewers with high interrater reliability (κ = .79). Cases were mostly international (82%), predominantly from Asia (50%) and Europe (27%). On average, patients were 42.6 years old (SD = 13.3) and had a neck mass ranging between 2 to 4 cm (52.7%) or >4 cm (43.2%). Nearly 70% of cases were asymptomatic at presentation. Presurgical diagnosis relied on CT (63.4%), MRI (59.8%), or both (19.5%), supplemented by cytology (33.7%), which was nearly always inconclusive (96.7%). US-treated cases were significantly more likely to receive presurgical MRI than internationally treated cases but less likely to have cytology (P 4 cm. Adverse events persisted in 82.3% of cases at an average 30.0 months (SD = 30.1) follow-up time. Given the typical CSCS patient is young and asymptomatic and the likelihood of persistent morbidity is high with standard surgical approaches, less invasive treatment options warrant consideration. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.
Full Text Available Pyogenic vertebral osteomyelitis (PVO is still a rare pathology. However, its incidence is on the rise. This is due to an increasing population with predisposing factors. Also, the availability of more effective diagnostic tools has brought it increasingly to the surgeon’s attention. In this study the patients were treated in the Neurosurgery Division of the Department of Neurological Sciences and Psychiatry of the Sapienza University of Rome, between 2001 and 2009. They had thoracolumbar pyogenic spondylitis. This study was undertaken in order to identify the correct diagnostic and therapeutic treatment needed in such cases. From the cases studied here, it is evident that spinal infections can be extremely insidious and that diagnosis tends to be reached late. Surgery, along with the antibiotic treatment, allows for eradication of the causes of the pathology by the reclamation of the affected region. Surgery is also fundamental in helping to recover vital functions and in restoring as much as possible the correct curvature of the rachises. The use of an anterolateral approach is dictated by the necessity of obtaining 360° stability as well as by the need to clear away extensive infections, which are not always reachable using a posterior approach.

There is worldwide interest in and increasing usage of the conservative atraumatic restorative treatment technique or approach for the restoration of primary and permanent teeth. However, most published data on the clinical performance of the newer, high-strength esthetic conventional glass-ionomer restorative cements marketed for the procedure have been derived from short-term studies. There have been very few reports comparing different types of restorative materials and methods of cavity preparation. In primary teeth, after 1 year, success rates have been approximately 80% to 95% for Class I and Class V single-surface restorations, 55% to 75% for Class II multisurface restorations, and 35% to 55% for Class III and Class IV restorations. In permanent teeth, after 2 to 3 years, success rates have been approximately 90% for Class I and Class V single-surface restorations, but little data have been reported for other restoration classes. Failures usually result from restoration losses, fractures, and wear. Further improvements in the design of hand instruments and in the mechanical properties of the newer glass-ionomer cements are required. Currently, use of the atraumatic restorative treatment approach should be restricted to restoration of single-surface caries lesions, especially in permanent teeth, and to sealing of occlusal fissures in selected teeth.

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia. Overactivation of the sympathetic nervous system (SNS) plays an important role in the pathogenesis of comorbidities related to AF such as hypertension, congestive heart failure, obesity, insulin resistance, and obstructive sleep apnea. Methods that reduce sympathetic drive, such as centrally acting sympatho-inhibitory agents, have been shown to reduce the incidence of spontaneous or induced atrial arrhythmias, suggesting that neuromodulation may be helpful in controlling AF. Moxonidine acts centrally to reduce activity of the SNS, and clinical trials indicate that this is associated with a decreased AF burden in hypertensive patients with paroxysmal AF and reduced post-ablation recurrence of AF in patients with hypertension who underwent pulmonary vein isolation (PVI). Furthermore, device-based approaches to reduce sympathetic drive, such as renal denervation, have yielded promising results in the prevention and treatment of cardiac arrhythmias. In light of these recent findings, targeting elevated sympathetic drive with either pharmacological or device-based approaches has become a focus of clinical research. Here, we review the data currently available to explore the potential utility of sympatho-inhibitory therapies in the prevention and treatment of cardiac arrhythmias.

Full Text Available Alzheimer disease (AD is the most common form of the dementia which occurs among older people above the age of 60 years. The Alzheimer’s disease once considered a rare disorder and it is now seen as a major public health problem that is seriously affecting millions of older people and their families world over. The incidence of AD ranges from 1 to 4 percent of the population per year rising from its lowest level at ages 65 to 70 years to rates that may approach 6 percent for those over the age of 85 years. Alzheimer's is characterised by massive loss of neurons and disrupted signaling between cells in the brain. The disease can be diagnosed post mortem by observing tangles inside and senile plaques outside cells throughout the brain. The major component of the plaques is a small, 40- or 42-amino acid peptide: amyloid beta (Aβ,. Aβ, causative agent in Alzheimer's, was first suggested as the amyloid hypothesis about 15 years ago and is now widely accepted amongst scientific community. The first neurotransmitter defect discovered in Alzheimer disease involved acetylcholine (ACh. As cholinergic function is required for short term memory, the cholinergic deficit in Alzheimer’s disease is also believed to be responsible for much of the short term memory deficit. The studies related to clinical trials of drugs in patients with Alzheimer disease have focused on the development of drugs augmenting the level of neurotransmitter acetylcholine in the brain in order to compensate for the loss of cholinergic function. Amongst these drugs, acetylcholine precursors, muscarinic agonists, nicotinic agonists and choline esterase inhibitors have extensively been studied in patients with Alzheimer’s disease and the successful approach to treat this disease have employed acetylcholineesterase (AChE inhibition. The clinical response of few drugs namely donepezil (Aricept, rivastigmine (Exelon, galantamine (Reminyl and Memantine (Nemenda approved by Food and

Botulinum toxin (BTX) injection into the cricopharyngeal (CP) muscle has been proposed for the treatment of neurogenic dysphagia due to CP hyperactivity. The aim was to determine whether an electrophysiological method exploring oropharyngeal swallowing could guide treatment and discriminate responders from non-responders, based on the association of CP dysfunction with other electrophysiological abnormalities of swallowing. Patients with different neurological disorders were examined: Parkinson disease, progressive supranuclear palsy, multiple system atrophy-Parkinson variant, multiple system atrophy cerebellar variant, stroke, multiple sclerosis and ataxia telangiectasia. All patients presented with clinical dysphagia, and with complete absence of CP muscle inhibition during the hypopharyngeal phase of swallowing. Each patient underwent clinical and electrophysiological investigations before and after treatment with BTX into the CP muscle of one side (15 units of Botox). Clinical and electrophysiological procedures were performed in a blind manner by two different investigators. The following electrophysiological measures were analysed: (1) duration of EMG activity of suprahyoid/submental muscles (SHEMG-D); (2) duration of laryngopharyngeal mechanogram (LPM-D); (3) duration of the inhibition of the CP muscle EMG activity (CPEMG-ID); and (4) interval between onset of EMG activity of suprahyoid/submental muscles and onset of laryngopharyngeal mechanogram (I-SHEMG-LPM). Two months after treatment, 50% of patients showed a significant improvement. Patients with prolonged or reduced SHEMG-D values and prolonged I-SHEMG-LPM values did not respond to BTX. Therefore, values for which BTX had no effect (warning values) were identified. This electrophysiological method can recognise swallowing abnormalities which may affect the outcome of the therapeutic approach to dysphagia with BTX treatment.

Full Text Available Background and aimsThere is a clear need for a new approach to the treatment of obesity which is inexpensive and is effective for establishing lifestyle change. We conducted a pilot study to evaluate whether dexamphetamine can be used safely, combined with diet and exercise, for treating obesity. Our ultimate aim is to develop a 6 month treatment program for establishing the lifestyle changes necessary for weight control, utilising dexamphetamine for its psychotropic effect on motivation. We viewed the anorexigenic effect as an additional advantage for promoting initial weight loss. Methods Obese adults were treated with dexamphetamine for 6 months (maximum of 30mg twice daily, diet and exercise. Weight, electrocardiogram, echocardiogram and blood pressure were monitored. ResultsTwelve out of 14 completed 6 months treatment. Weight loss by intention to treat was 10.6kg (95%CI 5.8-15.5, p<0.001. The mean weight gain in the 6 months after ceasing dexamphetamine was 4.5kg (95%CI 1.9 to 7.2, p=0.003, leaving a mean weight loss at 12 months from baseline of 7.0kg (95%CI -13.4 to -0.6, p=0.03. All reported favourable increases in energy and alertness. Dose-limiting symptoms were mood changes (2 and insomnia (2. None had drug craving on ceasing dexamphetamine and there were no cardiac complications. Among the 7 women, there was a significant correlation for those who lost most weight on treatment to have the least regain in the following 6 months (r=0.88, p=0.009.ConclusionsOur treatment with dexamphetamine, diet and exercise was well tolerated and effective for initial weight loss. Future research will focus on identifying baseline predictive variables associated with long-term weight control. Trial registration: ACTRN12612000831886

Recalcitrant warts represent a frustrating challenge for both patients and physicians. Although many destructive and immunotherapeutic modalities are available for the treatment of warts, an ideal, universally effective approach has not been explored to date. Recently, intralesional antigen immunotherapy has shown promising efficacy in the treatment of warts. The aim of the study was to evaluate the efficacy and safety of intralesional measles, mumps, and rubella (MMR) vaccine in the treatment of recalcitrant warts. The study included 70 adult patients with multiple recalcitrant extragenital warts of different sizes and durations, with or without distant warts. They were directly injected, without a pre-sensitization skin test, with 0.3 intralesional MMR vaccine into the largest wart at 2-week intervals until complete clearance or for a maximum of five treatments. Follow-up was made every month for six months to detect any recurrence. Sixty-five patients, 35 men and 30 women, completed the study, and five patients discontinued for various reasons. Complete clearance of the lesions was observed in 41 patients (63%), partial response in 15 patients (23%), and no response in nine patients (14%). Complete response was demonstrated in 74.5% of those presenting with distant warts. Side effects were mild and insignificant in the form of pain during injection, itching, erythema, and edema at the site of injection and flu-like symptoms. Recurrence was detected in two patients only. Intralesional immunotherapy by MMR vaccine is a promising, effective, and safe treatment modality for recalcitrant warts. © 2014 The International Society of Dermatology.

The management of symptomatic fibroids has traditionally been surgical; however, alternative pharmacological approaches have been proposed to control symptoms. To date, gonadotropin-releasing hormone analogs are the only available drugs for the preoperative treatment of fibroids. However, the US Food and Drug Administration recently authorized ulipristal acetate (UPA, an oral selective progesterone-receptor modulator, for the same indication. UPA is a new, effective, and well-tolerated option for the preoperative treatment of moderate and severe symptoms of uterine fibroids in women of reproductive age. According to clinical data, UPA shows several advantages: it is faster than leuprolide in reducing the fibroid-associated bleeding, it significantly improves hemoglobin and hematocrit levels in anemic patients, and it grants a significant reduction in the size of fibroids, which lasts for at least 6 months after the end of the treatment. Furthermore, UPA displays a better tolerability profile when compared to leuprolide; in fact, it keeps estradiol levels at mid follicular phase range, thereby reducing the incidence of hot flushes and exerting no impact on bone turnover. On the grounds of this evidence, the administration of 5 mg/day ulipristal acetate for 3 months is suggested for different patient categories and allows for planning a treatment strategy

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

Chronic pain is currently under-diagnosed and under-treated, partly because doctors' training in pain management is often inadequate. This situation looks certain to become worse with the rapidly increasing elderly population unless there is a wider adoption of best pain management practice. This paper reviews current knowledge of the development of chronic pain and the multidisciplinary team approach to pain therapy. The individual topics covered include nociceptive and neuropathic pain, peripheral sensitization, central sensitization, the definition and diagnosis of chronic pain, the biopsychosocial model of pain and the multidisciplinary approach to pain management. This last section includes an example of the implementation of a multidisciplinary approach in Belgium and describes the various benefits it offers; for example, the early multidimensional diagnosis of chronic pain and rapid initiation of evidence-based therapy based on an individual treatment plan. The patient also receives continuity of care, while pain relief is accompanied by improvements in physical functioning, quality of life and emotional stress. Other benefits include decreases in catastrophizing, self-reported patient disability, and depression. Improved training in pain management is clearly needed, starting with the undergraduate medical curriculum, and this review is intended to encourage further study by those who manage patients with chronic pain.

Full Text Available Abstract Varying surgical techniques, patient groups and results have been described regards the surgical treatment of post traumatic flexion contracture of the elbow. We present our experience using the limited lateral approach on patients with carefully defined contracture types. Surgical release of post-traumatic flexion contracture of the elbow was performed in 23 patients via a limited lateral approach. All patients had an established flexion contracture with significant functional deficit. Contracture types were classified as either extrinsic if the contracture was not associated with damage to the joint surface or as intrinsic if it was. Overall, the mean pre-operative deformity was 55 degrees (95%CI 48 – 61 which was corrected at the time of surgery to 17 degrees (95%CI 12 – 22. At short-term follow-up (7.5 months the mean residual deformity was 25 degrees (95%CI 19 – 30 and at medium-term follow-up (43 months it was 32 degrees (95%CI 25 – 39. This deformity correction was significant (p Surgical release of post-traumatic flexion contracture of the elbow via a limited lateral approach is a safe technique, which reliably improves extension especially for extrinsic contractures. In this series all patients with an extrinsic contracture regained a functional range of movement and were satisfied with their surgery.

In this paper, a new methodological approach to using PET information in radiotherapy treatment planning has been discussed. Computed tomography (CT) represents the primary modality to plan personalized radiation treatment, because it provides the basic electron density map for correct dose calculation. If PET scanning is also performed it is typically coregistered with the CT study. This operation can be executed automatically by a hybrid PET/CT scanner or, if the PET and CT imaging sets have been acquired through different equipment, by a dedicated module of the radiotherapy treatment planning system. Both approaches have some disadvantages: in the first case, the bore of a PET/CT system generally used in clinical practice often does not allow the use of certain bulky devices for patient immobilization in radiotherapy, whereas in the second case the result could be affected by limitations in window/level visualization of two different image modalities, and the displayed PET volumes can appear not to be related to the actual uptake into the patient. To overcome these problems, at our centre a specific procedure has been studied and tested in 30 patients, allowing good results of precision in the target contouring to be obtained. The process consists of segmentation of the biological target volume by a dedicated PET/CT console and its export to a dedicated radiotherapy system, where an image registration between the CT images acquired by the PET/CT scanner and a large-bore CT is performed. The planning target volume is contoured only on the large-bore CT and is used for virtual simulation, to individuate permanent skin markers on the patient.

Full Text Available ABSTRACTOBJECTIVES: To evaluate the clinical and radiographic results and complications relating to patients undergoing arthroscopic treatment for femoroacetabular impingement by means of an extracapsular approach. METHODS: Between January 2011 and March 2012, 49 patients (50 hips underwent arthroscopic treatment for femoroacetabular impingement, performed by the hip surgery team of the Orthopedic Hospital of Passo Fundo, Rio Grande do Sul. Forty patients (41 hips fulfilled all the requirements for this study. The mean follow-up was 29.1 months. The patients were assessed clinically by means of the Harris Hip score, as modified by Byrd (MHHS, the Non-Arthritic Hip score (NAHS and the internal rotation of the hip. Their hips were also evaluated radiographically, with measurement of the CE angle, dimensions of the joint space, alpha angle, neck-head index, degree of arthrosis and presence of heterotopic ossification of the hip. RESULTS: Out of the 41 hips treated, 31 (75.6% presented good or excellent clinical results. There was a mean postoperative increase of 22.1 points for the MHHS, 21.5 for the NAHS and 16.4° for the internal rotation of the hip ( p< 0.001. Regarding the radiographic evaluation, correction to normal values was observed for the alpha angle and neck-head index, with a mean postoperative decrease of 32.9° and mean increase of 0.10, respectively ( p< 0.001. CONCLUSION: Arthroscopic treatment of femoroacetabular impingement by means of an extracapsular approach presented satisfactory clinical and radiographic results over a mean follow-up of 29.1 months, with few complications.
Full Text Available Introduction The standard treatment of colo-vesical fistula is the exeresis of fistula, suture of bladder wall, colic resection with or without temporary colostomy. Usually the approach is open because conversion rates and morbidity are lower than laparoscopy. The aim of video is to show the steps of a new mini-invasive approach of colo-vesical fistula without colic resection. Materials and Methods A 69 years old male underwent laparoscopic conservative treatment of colo-vesical fistula due to endoscopic polipectomy in sigmoid diverticulum. 12 mm trocar for the camera was placed at the umbilicus, two 10 mm trocars were placed along bisiliac line and 5 mm port was placed along left emiclavear line; Trendelenburg position was 20°. The fistulous loop was carefully isolated, clipped with Hem-o-lock® clips and removed. Since diverticular disease appeared slight and no inflammation signs were evident, colon resection was not performed. We sutured and sinked the sigmoid wall; after curettage of the fistula site, the bladder wall was sutured. Fat tissue was placed between sigmoid and bladder wall to reduce the risk of fistula recurrence. Results Operative time, estimated blood loss, catheterization time, time to flatus and hospital stay were respectively 210 minutes, 300 mL, 10 days, 48 h and 8 days. The histological examination showed colonic inflammatory and necrotic tissue. No complications or fistula recurrence occurred at 54 months follow-up. Conclusions The laparoscopic conservative treatment of colo-vesical fistula is a safe and feasible technique, in particular when the diverticular disease is limited and the fistula is not due to diverticulitis.

Current therapies to treat Alzheimer's disease (AD) are focused on ameliorating symptoms instead of treating the underlying causes of AD. The accumulation of amyloid β (Aβ) oligomers, whether by an increase in production or by a decrease in clearance, has been described as the seed that initiates the pathological cascade in AD. Developing therapies to target these species is a vital step in improving AD treatment. Aβ-immunotherapy, especially passive immunotherapy, is a promising approach to reduce the Aβ burden. Up to now, several monoclonal antibodies (mAbs) have been tested in clinical trials on humans, but none of them have passed Phase III. In all likelihood, these trials failed mainly because patients with mild-to-moderate AD were recruited, and thus treatment may have been too late to be effective. Therefore, many ongoing clinical trials are being conducted in patients at the prodromal stage. New structures based on antibody fragments have been engineered intending to improve efficacy and safety. This review presents the properties of this variety of developing treatments and provides a perspective on state-of-the-art of passive Aβ-immunotherapy in AD.

Primitive neuroectodermal tumors of peripheral origin are very rare, and orbital neuroectodermal tumors are even more uncommon. Only 25 patients with primary orbital involvement in the pediatric age group have been reported. In this article, the authors describe their experience in the multimodality treatment approach to treat neuroectodermal tumor of the orbit. The authors also present a male patient 3-year old presenting with a neuroectodermal tumor of the right orbit causing rapidly progressive proptosis. The patient underwent an upper and lateral orbital marginotomy. The entire bone defect was reconstructed with a bone graft, allowing for the reconstruction of the floor and the lateral wall of the middle cranial fossa, the floor of the anterior cranial fossa, the upper and lateral orbital frame, and the right zygomatic bone. Over a period of 16 months, the patient was subjected to chemotherapy. In the postoperative period, a favorable evolution of the disease was observed, with growth in the reconstructed structures, good projection of the orbit and the eyeball, and stable results without tumor recurrence. The authors present the clinical analysis, surgical management, as well as the chemotherapy treatment established, with follow-ups at 1 and 2 and a half years. This experience shows the effectiveness of multimodality therapy in the treatment of rare tumors of difficult handling.

Chronic lymphocytic leukemia (CLL) is the most frequently diagnosed hematologic malignancy in the United States. Although several features can be useful in the diagnosis of CLL, the most important is the immunophenotype.Two staging systems--the Binet system and the Rai classification--are used to assess risk. After diagnosis, the first major therapeutic decision is when to initiate therapy, as a watchful waiting approach is often appropriate for patients with asymptomatic disease. Once a patient has met the criteria for treatment, the choice of therapy is the next major decision. Younger patients (<65 years) often receive more aggressive treatment that typically consists of cytotoxic chemotherapy. There is a great unmet need concerning treatment of older patients with CLL, who often present with more comorbid conditions that can decrease their ability to tolerate particular regimens. The current standard of care for older patients with CLL is rituximab plus chlorambucil. The concept of targeted agents is currently an area of intense interest in CLL. The Bruton’s tyrosine kinase inhibitor ibrutinib is the targeted agent that is furthest along in clinical development. It is associated with an overall survival rate of 83%. Idelalisib targets the phosphatidyl inositol 3-kinase and is under evaluation in pivotal trials. Targeted agents offer much promise in terms of efficacy, toxicity, and oral availability. They will change the management of patients with CLL.

Osteoarthritis (OA) is a multi-factor disorder of sinovial joints, which characterized by escalated degeneration and loss of articular cartilage. Treatment of OA is a critical unmet need in medicine for regeneration of damaged articular cartilage in elderly. On the other hand, lubricin, a glycoprotein specifically synthesized by chondrocytes located at the surface of articular cartilage, has been shown to provide boundary lubrication of congruent articular surfaces under conditions of high contact pressure and near zero sliding speed. Lubrication of these surfaces is critical to normal joint function, while different gene expressions of lubricin had been found in the synovium of rheumatoid arthritis (RA) and OA. Moreover, mutations or lacking of lubricin gene have been shown to link to the joint disease such as camptodactyly-arthropathy-coxa vara-pericarditis syndrome (CACP), synovial hyperplasia and failure of joint function, suggesting an important role of lubricin in the pathogenesis of these joint disease. Recent studies demonstrate that administration with recombinant lubricin in the joint cavity would be effective in the prevention of cartilage degeneration in animal OA models. Therefore, a treatment with lubricin which would protect cartilage in vivo would be desirable. This article reviews recent findings with regard to the possible role of lubricin in the progression of OA, and further discusses lubricin as a novel potential biotherapeutic approaches for the treatment of OA.

With increased worldwide awareness of environmental issues, healthcare waste (HCW) management has received much attention from both researchers and practitioners over the past decade. The task of selecting the optimum treatment technology for HCWs is a challenging decision making problem involving conflicting evaluation criteria and multiple stakeholders. In this paper, we develop an integrated decision making framework based on cloud model and MABAC method for evaluating and selecting the best HCW treatment technology from a multiple stakeholder perspective. The introduced framework deals with uncertain linguistic assessments of alternatives by using interval 2-tuple linguistic variables, determines decision makers' relative weights based on the uncertainty and divergence degrees of every decision maker, and obtains the ranking of all HCW disposal alternatives with the aid of an extended MABAC method. Finally, an empirical example from Shanghai, China, is provided to illustrate the feasibility and effectiveness of the proposed approach. Results indicate that the methodology being proposed is more suitable and effective to handle the HCW treatment technology selection problem under vague and uncertain information environment.

Full Text Available Abstract Background This paper describes the clinical management of four cases of shoulder impingement syndrome using a conservative multimodal treatment approach. Clinical Features Four patients presented to a chiropractic clinic with chronic shoulder pain, tenderness in the shoulder region and a limited range of motion with pain and catching. After physical and orthopaedic examination a clinical diagnosis of shoulder impingement syndrome was reached. The four patients were admitted to a multi-modal treatment protocol including soft tissue therapy (ischaemic pressure and cross-friction massage, 7 minutes of phonophoresis (driving of medication into tissue with ultrasound with 1% cortisone cream, diversified spinal and peripheral joint manipulation and rotator cuff and shoulder girdle muscle exercises. The outcome measures for the study were subjective/objective visual analogue pain scales (VAS, range of motion (goniometer and return to normal daily, work and sporting activities. All four subjects at the end of the treatment protocol were symptom free with all outcome measures being normal. At 1 month follow up all patients continued to be symptom free with full range of motion and complete return to normal daily activities. Conclusion This case series demonstrates the potential benefit of a multimodal chiropractic protocol in resolving symptoms associated with a suspected clinical diagnosis of shoulder impingement syndrome.

Primary idiopathic achalasia is the most common form of the rare esophageal motility disorders. A curative therapy which restores the normal motility does not exist; however, the therapeutic principle of cardiomyotomy according to Ernst Heller leads to excellent symptom control in the majority of cases. The established standard approach is Heller myotomy through the laparoscopic route (LHM), combined with Dor anterior fundoplication for reflux prophylaxis/therapy. At least four meta-analyses of randomized controlled trials (RCTs) have demonstrated superiority of LHM over pneumatic dilation (PD); therefore, LHM should be used as first line therapy (without prior PD) in all operable patients. Peroral endoscopic myotomy (POEM) is a new alternative approach, which enables Heller myotomy to be performed though the endoscopic submucosal route. The POEM procedure has a low complication rate and also leads to good control of dysphagia but reflux rates can possibly be slightly higher (20-30%). Long-term results of POEM are still scarce and the results of the prospective randomized multicenter trial POEM vs. LHM are not yet available; however, POEM seems to be the preferred treatment option for certain indications. Within the framework of the tailored approach for achalasia management of POEM vs. LHM established in Würzburg, we recommend long-segment POEM for patients with type III achalasia (spasmodic) and other hypercontractile motility disorders and potentially type II achalasia (panesophageal compression) with chest pain as the lead symptom, whereas LHM can also be selected for type I. For sigmoid achalasia, especially with siphon-like transformation of the esophagogastric junction, simultaneous hiatal hernia and epiphrenic diverticula, LHM is still the preferred approach. The choice of the procedure for revisional surgery in case of recurrent dysphagia depends on the suspected mechanism (morphological vs. functional/neuromotor).

Nowadays, clinical practice in Gamma Knife treatments is generally based on MRI anatomical information alone. However, the joint use of MRI and PET images can be useful for considering both anatomical and metabolic information about the lesion to be treated. In this paper we present a co-segmentation method to integrate the segmented Biological Target Volume (BTV), using [(11)C]-Methionine-PET (MET-PET) images, and the segmented Gross Target Volume (GTV), on the respective co-registered MR images. The resulting volume gives enhanced brain tumor information to be used in stereotactic neuro-radiosurgery treatment planning. GTV often does not match entirely with BTV, which provides metabolic information about brain lesions. For this reason, PET imaging is valuable and it could be used to provide complementary information useful for treatment planning. In this way, BTV can be used to modify GTV, enhancing Clinical Target Volume (CTV) delineation. A novel fully automatic multimodal PET/MRI segmentation method for Leksell Gamma Knife(®) treatments is proposed. This approach improves and combines two computer-assisted and operator-independent single modality methods, previously developed and validated, to segment BTV and GTV from PET and MR images, respectively. In addition, the GTV is utilized to combine the superior contrast of PET images with the higher spatial resolution of MRI, obtaining a new BTV, called BTVMRI. A total of 19 brain metastatic tumors, undergone stereotactic neuro-radiosurgery, were retrospectively analyzed. A framework for the evaluation of multimodal PET/MRI segmentation is also presented. Overlap-based and spatial distance-based metrics were considered to quantify similarity concerning PET and MRI segmentation approaches. Statistics was also included to measure correlation among the different segmentation processes. Since it is not possible to define a gold-standard CTV according to both MRI and PET images without treatment response assessment

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

BRAF inhibitors vemurafenib and dabrafenib achieved improved overall survival over chemotherapy and have been approved for the treatment of BRAF-mutated metastatic melanoma. More recently, the combination of BRAF inhibitor dabrafenib with MEK inhibitor trametinib has shown improved progression-free survival, compared to dabrafenib monotherapy, in a Phase II study and has received approval by the US Food and Drug Administration. However, even when treated with the combination, most patients develop mechanisms of acquired resistance, and some of them do not achieve tumor regression at all, because of intrinsic resistance to therapy. Along with the development of BRAF inhibitors, immunotherapy made an important step forward: ipilimumab, an anti-CTLA-4 monoclonal antibody, was approved for the treatment of metastatic melanoma; anti-PD-1 agents achieved promising results in Phase I/II trials, and data from Phase III studies will be ready soon. The availability of such drugs, which are effective regardless of BRAF status, has made the therapeutic approach more complex, as first-line treatment with BRAF inhibitors may not be the best choice for all BRAF-mutated patients. The aim of this paper is to review the systemic therapeutic options available today for patients affected by BRAF V600-mutated metastatic melanoma, as well as to summarize the mechanisms of resistance to BRAF inhibitors and discuss the possible strategies to overcome them. Moreover, since the molecular analysis of tumor specimens is now a pivotal and decisional factor in the treatment strategy of metastatic melanoma patients, the advances in the molecular detection techniques for the BRAF V600 mutation will be reported.

A recent meta-analysis showed that long-acting injectable (LAI) antipsychotics were not superior to oral antipsychotics for preventing relapse in patients with schizophrenia. We therefore designed a treatment strategy combining risperidone LAI and COMPASS (COMprehensive Psycho-educational Approach and Scheme Set), an original psychoeducational program supporting treatment with risperidone LAI and evaluating subjective treatment satisfaction, transition of symptoms, and effectiveness in preventing symptomatic relapse. The aim of this study was to examine whether addition of COMPASS to risperidone LAI was more effective in preventing relapse in schizophrenia patients than risperidone LAI alone, with the latter group consisting of patients enrolled in a Phase III trial of risperidone LAI in Japan. Patients were followed up for 6 months, with COMPASS continuously implemented from the transition to the observation phase. The primary efficacy measurements were relapse rate (rates of rehospitalization and discontinuation due to inefficacy). Secondary efficacy measurements were the Brief Psychiatric Rating Scale (BPRS) and Global Assessment of Functioning (GAF) scores. Of the 96 patients originally enrolled, 19 (19.8%) were discontinued from all causes. During the 6-month study period, ten of the 96 patients (10.4%) relapsed, compared with a 12.2% relapse rate in patients enrolled in a Phase III trial of risperidone LAI in Japan. Patients showed significant improvements in BPRS total scores (P = 0.0031), BPRS positive (P = 0.0451), BRPS negative (P < 0.0001), and general subscale scores (P = 0.0031), and GAF (P < 0.0001) from baseline to 6 months. In conclusion, the lower relapse rate observed in patients treated with COMPASS plus risperidone LAI than in patients treated with risperidone LAI alone suggests that COMPASS may have benefits in the treatment of schizophrenia, indicating a need for randomized, controlled trials in larger numbers of patients.

Till date, successful treatment of depression using taping therapy has not been known yet. We report cases where patients with severe depressive symptoms were successfully treated by taping therapy, a new approach.Methods: In case 1, a patient was taking several psychiatric medications for 10 years and admitted often to the psychiatric hospital with a leaning head, flexible legs, and nearly closed eyes; in case 2, a patient after a hysterectomy complained with heart palpitations, depressive- and anxiety-like behaviors, insomnia, and gastrointestinal problems; and in case 3, a patient with complaints of adverse effects from antidepressant medications had suicidal thoughts frequently. The medical tapes were placed on acupoints, trigger points, and pain points found by finger pressing examination in the chest, sides, and upper back of the patients.Results: In case 1, the patient started weeping immediately after the first treatment. He discontinued psychiatric drugs and returned to baseline functioning after 2 months. In case 2, the patient felt at ease showing decreased palpitation immediately after the first treatment, and after 1 week, she quit medications. In case 3, the patient experienced a

Rapid development of novel treatment options demands valid preclinical screening models for urothelial carcinoma (UC). The translational value of high-throughput drug testing using 2-dimensional (2D) cultures is limited while for xenograft models handling efforts and costs often become prohibitive for larger-scale drug testing. Therefore, we investigated to which extent the chicken chorioallantoic membrane (CAM) assay might provide an alternative model to study antineoplastic treatment approaches for UC. The ability of 8 human UC cell lines (UCCs) to form tumors after implantation on CAMs was investigated. Epithelial-like RT-112 and mesenchymal-like T-24 UCCs in cell culture or as CAM tumors were treated with cisplatin alone or combined with histone deacetylase inhibitors (HDACi) romidepsin and suberanilohydroxamic acid. Tumor weight, size, and bioluminescence activity were monitored; tumor specimens were analyzed by histology and immunohistochemistry. Western blotting and quantitative real time polymerase chain reaction were used to measure protein and mRNA expression. UCCs were reliably implantable on the CAM, but tumor development varied among cell lines. Expression of differentiation markers (E-cadherin, vimentin, CK5, CK18, and CK20) was similar in CAM tumors and 2D cultures. Cellular phenotypes also remained stable after recultivation of CAM tumors in 2D cultures. Bioluminescence images correlated with tumor weight. Cisplatin and HDACi decreased weight and growth of CAM tumors in a dose-dependent manner, but HDACi treatment acted less efficiently as in 2D cultures, especially on its typically associated molecular markers. Synergistic effects of HDACi and subsequent cisplatin treatment on UCCs were neither detected in 2D cultures nor detected in CAM tumors. Our results demonstrate that the CAM assay is a useful tool for studying tumor growth and response to conventional anticancer drugs under 3D conditions, especially cytotoxic drugs as cisplatin.

Although the latter condition may be referred to surgery, drug therapy is usually the first approach to control pain. This study compared the clinical outcome and direct costs of (1 a traditional treatment (carbamazepine [CBZ] in monotherapy [CBZ protocol], (2 the association of gabapentin (GBP and analgesic block of trigger-points with ropivacaine (ROP (GBP+ROP protocol, and (3 a common TN surgery, microvascular decompression of the trigeminal nerve (MVD protocol. Sixty-two TN patients were randomly treated during 4 weeks (CBZ [n = 23] and GBP+ROP [n = 17] protocols from cases of idiopathic TN, or selected for MVD surgery (n = 22 due to intractable pain. Direct medical cost estimates were determined by the price of drugs in 2008 and the hospital costs.

The current paper discusses an approach to measuring treatment integrity of dialectical behavioral therapy (DBT) when implemented within two programs providing services to street-involved youth in the community. Measuring treatment integrity is a critical component of effective implementation of evidence-based interventions in clinical practice, since sound treatment integrity increases confidence in client outcomes and intervention replicability. Despite being an essential part of implementation science, few studies report on treatment integrity, with limited research addressing either measurement tools or maintenance of treatment integrity. To address the lack of available treatment integrity measures, researchers in the current study developed and piloted a treatment integrity measure which pertain to the individual and group components of DBT. A total of 20 recordings were assessed using the treatment integrity measure. Results indicate that the community agency staff (e.g. youth workers, social workers & nurses) implemented the intervention as intended; increasing confidence in the outcome variables, the staffs' training and the replicability of the intervention. This article offers one approach to addressing treatment integrity when implementing evidence-based interventions, such as DBT in a community setting, and discusses the need for effective and feasible integrity measures that can be adopted in order to strengthen mental health practice in community settings.

The aim of this report is to present a combined treatment approach with gingivectomy and CO2 laser for the management of cyclosporine-induced gingival overgrowth in 4 cases. Four renal transplant patients were surgically treated for marked gingival overgrowth by means of gingivectomy and CO2 laser. Postoperatively, all patients were followed for bleeding, pain, infection during the early healing period, and recurrence of gingival overgrowth for 12 months. The healing was uneventful, and no signs of bleeding, postoperative pain, or infection were observed in any patient during the early healing period. In the 12th postoperative month, there was evidence of mild recurrence in 1 patient, while no sign of recurrence was observed in the other patients during the follow-up period. The advantages of this combined technique include satisfactory bleeding control and clear visibility during the procedure, as well as reduced postoperative pain and swelling.

Traumatic injuries in the primary dentition pose major challenges for management. This emergency treatment requires proper planning so as to achieve favorable results. Trauma causing severe dentoalveolar injuries, especially in children, needs an interdisciplinary approach so as to retain normal functional anatomy for that age. This article describes a clinical innovative technique, which utilizes a resorbable membrane in management of pediatric dentoalveolar trauma. The membrane was shaped to cover the multiple alveolar bone fracture, thereby favoring the healing of the bone defects. The use of this resorbable membrane maintained a secluded space for the bone growth and prevented overgrowth of the soft tissue in the region of the defect. This resulted in uneventful healing leading to well-maintained functional bone contour, which further favored the esthetic rehabilitation as well as protected the underlying permanent tooth buds.

This study compares the efficacy of the Community Reinforcement Approach (CRA) with and without an incentive program for cocaine-dependent patients in Spain. A total of 58 patients were randomly assigned to the CRA or CRA plus vouchers condition. In the CRA plus vouchers group, mean percentage of cocaine-negative samples was 97.07%, versus 79.76% in the no-voucher group. Those treated in the CRA plus vouchers condition also achieved greater improvements in psychosocial functioning than those treated in the CRA condition. The present results show that treatment outcome is better if incentives are delivered contingent upon the submission of cocaine-free urine specimens.

Small cell undifferentiated carcinoma (SmCC) of the gastrointestinal tract (GIT) is a rare and highly aggressive malignancy. To date, fewer than 1,000 cases have been reported, with an estimated prevalence of 0.1% to 1% of all gastrointestinal (GI) tumors. Data on the disease are scarce due to its rarity and the fact that most authors have focused on one site within the GIT. In light of the limited data and its perceived similarity to SmCC of the lung, the disease has usually been treated as the latter. Nevertheless, recent clinicopathologic and molecular data imply several differences between the two entities, questioning the extent to which extrapolations from one to the other can be made. We review the available data on GI SmCC with emphasis on outlining its clinicopathologic features and the recommended treatment approach.
Full Text Available Lichen planus(LPis a common chronic mucocutaneous disease of unknown etiology. Usually, it presents with lesions on the flexor surfaces of the upper extremities, genitalia and mucous membranes. Oral lesions can be the initial as well as the only manifestations of this condition. Patients with LP can present first to the general dental practitioner so sufficient knowledge on this condition is important for the proper diagnosis, treatment and prevention of further complications. The clinical management of LRP requires liaison between dental and medical specialists.This article provides a review of the current literature on LP and a case report of a 55 years old female suffering with this condition. A multidisciplinary approach in the diagnosis and management of this case is described.
Full Text Available Objective This study evaluated the hydrophobicity of dentin surfaces that were modified through chemical silanization with octadecyltrichlorosilane (OTS. Material and Methods An in vitro experimental study was performed using 40 human permanent incisors that were divided into the following two groups: non-silanized and silanized. The specimens were pretreated and chemically modified with OTS. After the chemical modification, the dentin hydrophobicity was examined using a water contact angle measurement (WCA. The effectiveness of the modification of hydrophobicity was verified by the fluid permeability test (FPT. Results and Conclusions Statistically significant differences were found in the values of WCA and FPT between the two groups. After silanization, the hydrophobic intraradicular dentin surface exhibited in vitro properties that limit fluid penetration into the sealed root canal. This chemical treatment is a new approach for improving the sealing of the root canal system.
Full Text Available This review presents the results of the 2013 Advancing IPF Research (AIR survey, which assessed current approaches to the diagnosis and treatment of idiopathic pulmonary fibrosis (IPF by experienced physicians. A total of 149 physicians, predominantly from European countries, replied to the 28-question survey. The results of the AIR survey were compared with a similar survey of 509 French pulmonologists conducted by the French National Reference Centre and the Network of Regional Competence Centres for Rare Lung Diseases. A number of positive findings emerged from the AIR survey, including the high level of multidisciplinary team involvement in both diagnosis and management. This survey, when taken together with the French survey, suggests that there is still a need to improve earlier diagnosis of IPF.

Type 1 diabetes is characterized by near total absence of pancreatic b cells. Current treatments consisting of insulin injections and islet transplantation are clinically unsatisfactory. In order to develop a cure for type 1 diabetes, we must find a way to reverse autoimmunity, which underlies b cell destruction, as well as an effective strategy to generate new b cells. This article reviews the different approaches that are being taken to produce new b cells. Much emphasis has been placed on selecting the right non-b cell population, either in vivo or in vitro, as the starting material. Different cell types, including adult stem cells, other types of progenitor cells in situ, and even differentiated cell populations, as well as embryonic stem cells and induced pluripotent stem cells, will require different methods for islet and b cell induction. We discussed the pros and cons of the different strategies that are being used to re-invent the pancreatic b cell.
Acne is a chronic inflammatory human skin disease, characterized by areas of skin with seborrhoea, comedones, papules, nodules, pimples, and possibly scarring with lesions occurring on face, neck, and back. Nanotechnological approaches such as particulate (solid lipid nanoparticles and microspheres), vesicular (liposomes and niosomes), colloidal drug delivery systems (micro-emulsion and nano-emulsion), and miscellaneous systems (aerosol foams and micro-sponges) have an important place in acne therapy. These approaches have an enormous opportunity for the designing of a novel, low-dose and effective treatment systems to control acne disease. In this review, we specially focus on the different nanotechnological approaches for an effective treatment of acne.
Full Text Available New treatments are needed for severe asthmatics to improve disease control and avoid severe toxicities associated with oral corticosteroids. We have used a murine model of house dust mite (HDM-induced asthma to identify steroid-unresponsive genes that might represent targets for new therapeutic approaches for severe asthma. This strategy identified apolipoprotein E as a steroid-unresponsive gene with increased mRNA expression in the lungs of HDM-challenged mice. Furthermore, apolipoprotein E functioned as an endogenous negative regulator of airway hyperreactivity and goblet cell hyperplasia in experimental HDM-induced asthma. The ability of apolipoprotein E, which is expressed by lung macrophages, to attenuate AHR and goblet cell hyperplasia is mediated by low density lipoprotein (LDL receptors expressed by airway epithelial cells. Consistent with this, administration of an apolipoprotein E mimetic peptide, corresponding to amino acids 130 to 149 of the LDL receptor-binding domain of the holo-apoE protein, significantly reduced AHR and goblet cell hyperplasia in HDM-challenged apoE-/- mice. These findings identified the apolipoprotein E - LDL receptor pathway as a new druggable target for asthma that can be activated by administration of apoE mimetic peptides. Similarly, apolipoprotein A-I may have therapeutic potential in asthma based upon its anti-inflammatory, anti-oxidative and anti-fibrotic properties. Furthermore, administration of apolipoprotein A-I mimetic peptides has attenuated airway inflammation, airway remodeling and airway hyperreactivity in murine models of experimental asthma. Thus, site-directed delivery of inhaled apolipoprotein E or apolipoprotein A-I mimetic peptides may represent novel treatment approaches that can be developed for asthma, including severe disease.

Purpose: To assess the feasibility and the effectiveness of endovascular treatment of visceral arteries aneurysms (VAAs) using a 'multimodal approach'. Material and methods: Twenty-five patients (mean age 60.1 years) with 29 VAAs (13 splenic, 4 hepatic, 3 gastroduodenal, 6 renal, 2 pancreatic-duodenal, 1 superior mesenteric) were considered suitable for endovascular treatment; 8/29 were ruptured. Saccular aneurysms (9/29) were treated by sac embolization with coils (in 4 cases associated with cyanoacrylate or thrombin) with preservation of artery patency. Fusiform aneurysms (6/29), were treated by an 'endovascular exclusion'. In 10/29 cases, supplied by a terminal branch, we performed an embolization of the afferent artery, with coils and cyanoacrylate or thrombin. 2/29 cases were treated with a stent-graft and 2/29 cases with a percutaneous ultrasound-guided thrombin injection and coils embolization of the afferent artery. The follow-up was performed by ultrasonography and/or CT-angiography 1 week after the procedure and then after 1, 6, and 12 months and thereafter annually. Results: In 29/29 cases we obtained an immediate exclusion. Two patient died for other reasons. Complication rate was 27.6% (7 spleen ischemia and 1 stent-graft occlusion). During the follow-up (range: 7 days-36 months, mean 18.7 months), we observed 3/29 (10.3%) cases of reperfusion in the first month, all treated successfully with a further endovascular procedure. Primary technical success was 89.7%; secondary technical success was 100%. Conclusion: Endovascular therapy can be considered a feasible and effective approach for VAAs with good primary and secondary success rates.

Posttraumatic stress disorder is a common cause of morbidity in children and adolescents. The disorder in youth is similar to that in adults, with high rates of psychiatric comorbidity. Children seem to be more sensitive to the effects of trauma, and early life trauma exposure may induce a complex sequence of events that leads to the development of multiple psychiatric disorders in adulthood. The state of knowledge regarding medication treatments for children and adolescents is in the earliest stages of development. There are no well-conducted, randomized clinical trials to guide practitioners. Medication may play an important role in reducing debilitating symptoms of PTSD and providing a buffer for children while they confront difficult material in therapy and may help to improve their general functioning in day-to-day life. Given the various medications with potential usefulness in PTSD, it is helpful to use a stepwise approach to treatment. As a general principal, broad-spectrum agents, such as the SSRIs, are a good first choice. The SSRIs have efficacy in treating the core symptoms of PTSD and conditions such as the anxiety disorders and depression that commonly co-occur with PTSD. These agents also improve social and occupational functioning and an individual's perception of improved quality of life [41, 45, 46]. Although the SSRIs are generally effective for a broad spectrum of problems, clinicians should systematically monitor for the persistence of symptoms that do not respond to these agents. For example, despite significant improvements in core PTSD symptoms in one study that used sertraline, little improvement was seen in patients' comorbid anxiety and depressive symptoms . This finding demonstrates the value of continuous symptom monitoring and shows that residual or comorbid symptoms may require a different medication to augment effective SSRI treatment for PTSD. A reasonable approach is to begin with a broad-spectrum agent, such as an SSRI, which

Attention-deficit/hyperactivity disorder (ADHD) is a prevalent and chronic mental health condition that often results in substantial impairments throughout life. Although evidence-based pharmacological and psychosocial treatments exist for ADHD, effects of these treatments are acute, do not typically generalize into non-treated settings, rarely sustain over time, and insufficiently affect key areas of functional impairment (i.e., family, social, and academic functioning) and executive functioning. The limitations of current evidence-based treatments may be due to the inability of these treatments to address underlying neurocognitive deficits that are related to the symptoms of ADHD and associated areas of functional impairment. Although efforts have been made to directly target the underlying neurocognitive deficits of ADHD, extant neurocognitive interventions have shown limited efficacy, possibly due to misspecification of training targets and inadequate potency. We argue herein that despite these limitations, next-generation neurocognitive training programs that more precisely and potently target neurocognitive deficits may lead to optimal outcomes when used in combination with specific skill-based psychosocial treatments for ADHD. We discuss the rationale for such a combined treatment approach, prominent examples of this combined treatment approach for other mental health disorders, and potential combined treatment approaches for pediatric ADHD. Finally, we conclude with directions for future research necessary to develop a combined neurocognitive + skill-based treatment for youth with ADHD.

Full Text Available Emma L Lane, Olivia J Handley, Anne E Rosser, Stephen B DunnettBrain Repair Group, School of Biosciences, Cardiff University, CF10 3US, UKAbstract: Parkinson’s disease is most commonly treated with a range of pharmacotherapeutics, with the more recent introduction of surgical techniques including deep-brain stimulation. These have limited capabilities to improve symptoms of the disease in more advanced stages, thus new therapeutic strategies including the use of viral vectors and stem cells are in development. Providing a continuous supply of dopamine to the striatum in an attempt to improve the treatment of motor symptoms using enzymes in the dopamine synthesis and machinery is one approach. Alternatively, there are tools which may serve to both protect and encourage outgrowth of surviving neurons using growth factors or to directly replace lost innervation by transplantation of primary tissue or stem cell-derived dopaminergic neurons. We summarize some of the potential therapeutic approaches and also consider the recent EU directives on practical aspects of handling viral vectors, cells and tissues, and in the running of clinical trials in Europe which impact on their development.Keywords: transplantation, viral vector, stem cells, ethics, European Union directive
Over the last decade, our research team has investigated the dynamic responses and global properties of living cells using systems biology approaches. More specifically, we have developed computational models and statistical techniques to interpret instructive cell signaling and high-throughput transcriptome-wide behaviors of immune, cancer, and embryonic development cells. Here, I will focus on our recent works in overcoming cancer resistance. TRAIL (tumor necrosis factor related apoptosis-inducing ligand), a proinflammatory cytokine, has shown promising success in controlling cancer threat due to its ability to induce apoptosis in cancers specifically, while having limited effect on normal cells. Nevertheless, several malignant cancer types, such as fibrosarcoma (HT1080) or colorectal adenocarcinoma (HT29), remain non-sensitive to TRAIL. To sensitize HT1080 to TRAIL treatment, we first developed a dynamic computational model based on perturbation-response approach, to predict a crucial co-target to enhance cell death. The model simulations suggested that PKC inhibition together with TRAIL induce 95% cell death. Subsequently, we confirmed this result experimentally utilizing the PKC inhibitor, bisindolylmaleimide (BIM) I, and PKC siRNAs in HT1080. Copyright © 2017 Elsevier Ltd. All rights reserved.

Purpose: The aim of this study was to evaluate the pregnancy outcomes in women with Hodgkin lymphoma (HL) diagnosis, treated between 1972 and 1999 at Department of Radiotherapy and Hematology of University 'Sapienza' of Roma. Methods and Materials: We retrospectively studied 99 female patients that conceived after treatment for HL. Fifty-nine (59%) were treated with chemotherapy and radiotherapy, 32 (32%) with radiotherapy alone as supradiaphragmatic or as infradiaphragmatic and 8 (8%) patients with chemotherapy alone. Results: Ninety-nine patients reported 145 pregnancies. We observed 132 deliveries (2 of them twin births) after a median of 55 months (range, 14-278 months) from the end of therapy. Twelve women (12%) experienced 13 miscarriages after a median of 50 months (range, 13-120) from the end of therapy. We recorded 9/132 (7%) premature births and 3/134 babies (2%) were underweight at the time of birth. We recorded 2 cases of congenital malformations. No statistical differences were recorded when adverse pregnancy outcomes were analyzed with respect to chemotherapy alone, radiotherapy alone, or combined therapy. Conclusions: No significant associations between pregnancy outcomes and therapeutic approaches were found. In particular, the infradiaphragmatic radiotherapy showed no statistical association with miscarriages, premature birth, and low birth weight at term when compared with other therapeutic approaches.

Full Text Available Intracytoplasmic sperm injection into an oocyte is widely used throughout the world in assisted reproductive technologies programs in the presence of male infertility factor. However, this approach can allow selection of a single sperm, which is carrying different types of pathologies. Minimizing of any potential risks, entailing the occurrence of abnormalities in the embryos development (apoptosis, fragmentation of embryos, alterations in gene expression, aneuploidies is a very important condition for reducing the potential negative consequences resulting the manipulation with gametes. Processes that could be influenced by the embryologist must be fulfilled in safe and physiological way as much as it is possible. Data of numerous publications reporting about the positive effects of using the technology of sperm selection by hyaluronic acid binding, let make a conclusion about the high prospects of this approach in the treatment of male infertility by methods of in vitro fertilization. The selection of sperm with improved characteristics, which determine the maturity and genetic integrity, provides an opportunity to improve the parameters of pre-implantation embryogenesis, having thus a positive effect on clinical outcomes of assisted reproductive technologies programs.
Full Text Available Introduction. Molar incisor hypomineralization (MIH was defined as "hypomineralisation of systemic origin of permanent first molars, frequently associated with affected incisors". MIH includes the presence of demarcated opacity, post eruptive enamel breakdown, atypical restoration. Тhe approach to management suggested: risk identification, early diagnosis, remineralization for prevention of caries and post eruption breakdown, restorations. The clinicians very seldom notice that children with MIH usually have both- hypomineralisation and malocclusions, and they do not discuss combine treatment plan.Aim. To present our interdisciplinary approach to a patient with MIH, combined with malocclusion.Material and methods.

Chronic pain affects nearly 116 million American adults at an estimated cost of up to $635 billion annually and is the No. 1 condition for which patients seek care at integrative medicine clinics. In our Study on Integrative Medicine Treatment Approaches for Pain (SIMTAP), we observed the impact of an integrative approach on chronic pain and a number of other related patient-reported outcome measures. Our prospective, non-randomized, open-label observational evaluation was conducted over six months, at nine clinical sites. Participants received a non-standardized, personalized, multimodal approach to chronic pain. Validated instruments for pain (severity and interference levels), quality of life, mood, stress, sleep, fatigue, sense of control, overall well-being, and work productivity were completed at baseline and at six, 12, and 24 weeks. Blood was collected at baseline and week 12 for analysis of high-sensitivity C-reactive protein and 25-hydroxyvitamin D levels. Repeated-measures analysis was performed on data to assess change from baseline at 24 weeks. Of 409 participants initially enrolled, 252 completed all follow-up visits during the 6 month evaluation. Participants were predominantly white (81%) and female (73%), with a mean age of 49.1 years (15.44) and an average of 8.0 (9.26) years of chronic pain. At baseline, 52% of patients reported symptoms consistent with depression. At 24 weeks, significantly decreased pain severity (-23%) and interference (-28%) were seen. Significant improvements in mood, stress, quality of life, fatigue, sleep and well-being were also observed. Mean 25-hydroxyvitamin D levels increased from 33.4 (17.05) ng/mL at baseline to 39.6 (16.68) ng/mL at week 12. Among participants completing an integrative medicine program for chronic pain, significant improvements were seen in pain as well as other relevant patient-reported outcome measures.

To investigate biosystems, we propose a new thermodynamic concept that analyses ion, mass and energy flows across the cell membrane. This paradigm-shifting approach has a wide applicability to medically relevant topics including advancing cancer treatment. To support this claim, we revisit ‘Norton-Simon’ and evolving it from an already important anti-cancer hypothesis to a thermodynamic theorem in medicine. We confirm that an increase in proliferation and a reduction in apoptosis trigger a maximum of ATP consumption by the tumor cell. Moreover, we find that positive, membrane-crossing ions lead to a decrease in the energy used by the tumor, supporting the notion of their growth inhibitory effect while negative ions apparently increase the cancer’s consumption of energy hence reflecting a growth promoting impact. Our results not only represent a thermodynamic proof of the original Norton-Simon hypothesis but, more concretely, they also advance the clinically intriguing and experimentally testable, diagnostic hypothesis that observing an increase in negative ions inside a cell in vitro, and inside a diseased tissue in vivo, may indicate growth or recurrence of a tumor. We conclude with providing theoretical evidence that applying electromagnetic field therapy early on in the treatment cycle may maximize its anti-cancer efficacy.

Two common procedures for the treatment of missing information, listwise deletion and positive urine analysis (UA) imputation (e.g., if the participant fails to provide urine for analysis, then score the UA positive), may result in significant biases during the interpretation of treatment effects. To compare these approaches and to offer a possible alternative, these two procedures were compared to the multiple imputation (MI) procedure with publicly available data from a recent clinical trial. Listwise deletion, single imputation (i.e., positive UA imputation), and MI missing data procedures were used to comparatively examine the effect of two different buprenorphine/naloxone tapering schedules (7- or 28-days) for opioid addiction on the likelihood of a positive UA (Clinical Trial Network 0003; Ling et al., 2009). The listwise deletion of missing data resulted in a nonsignificant effect for the taper while the positive UA imputation procedure resulted in a significant effect, replicating the original findings by Ling et al. (2009). Although the MI procedure also resulted in a significant effect, the effect size was meaningfully smaller and the standard errors meaningfully larger when compared to the positive UA procedure. This study demonstrates that the researcher can obtain markedly different results depending on how the missing data are handled. Missing data theory suggests that listwise deletion and single imputation procedures should not be used to account for missing information, and that MI has advantages with respect to internal and external validity when the assumption of missing at random can be reasonably supported.

Full Text Available Osteoporosis is a common disease characterised by low bone density and brittle bone due to osteoblast–osteoclast uncoupling. The cellular and molecular mechanisms responsible for osteoblast–osteoclast coupling lead to the identification of novel therapeutic targets. The increasing evidence for a role for Eph–ephrin signalling in biological processes, including cell–cell interactions, cell morphology, cell migration, angiogenesis, cancer and bone homeostasis, identifies new molecular pathways and potentially novel therapeutic targets for the treatment of diseases. Recent studies suggest that the interactions between Eph and ephrin play critical roles in bone cell differentiation and patterning by exerting dimorphic effects on osteoblast and osteoclast differentiation, resulting in the intriguing coupling of bone resorption and bone formation. These findings suggest that interventions targeting osteoblast–osteoclast coupling by the regulation of the Eph–ephrin bidirectional signalling according to its biological effects, which results in inhibiting osteoclastic resorption and promoting osteoblastic formation, may be a promising approach for osteoporosis prevention and treatment in the near future.

Full Text Available Abstract Background Recently, trials addressing noisy measurements with diagnosis occurring by exceeding thresholds (such as diabetes and hypertension have been published which attempt to measure carryover - the impact that treatment has on an outcome after cessation. The design of these trials has been criticised and simulations have been conducted which suggest that the parallel-designs used are not adequate to test this hypothesis; two solutions are that either a differing parallel-design or a cross-over design could allow for diagnosis of carryover. Methods We undertook a systematic simulation study to determine the ability of a cross-over or a parallel-group trial design to detect carryover effects on incident hypertension in a population with prehypertension. We simulated blood pressure and focused on varying criteria to diagnose systolic hypertension. Results Using the difference in cumulative incidence hypertension to analyse parallel-group or cross-over trials resulted in none of the designs having acceptable Type I error rate. Under the null hypothesis of no carryover the difference is well above the nominal 5 % error rate. Conclusions When a treatment is effective during the intervention period, reliable testing for a carryover effect is difficult. Neither parallel-group nor cross-over designs using the difference in cumulative incidence appear to be a feasible approach. Future trials should ensure their design and analysis is validated by simulation.

Biofilm process is widely used for the treatment of a variety of wastewater especially containing slowly biodegradable substances. It provides resistance against toxic environment and is capable of retaining biomass under continuous operation. Development of kinetics is very much pertinent for rational design of a biofilm process for the treatment of wastewater with or without inhibitory substances. A simple approach for development of such kinetics for an aerobic biofilm reactor has been presented using a novel biofilm model. The said biofilm model is formulated from the correlations between substrate concentrations in the influent/effluent and at biofilm liquid interface along with substrate flux and biofilm thickness complying Monod's growth kinetics. The methodology for determining the kinetic coefficients for substrate removal and biomass growth has been demonstrated stepwise along with graphical representations. Kinetic coefficients like K, k, Y, b t, b s, and b d are determined either from the intercepts of X- and Y-axis or from the slope of the graphical plots.

Full Text Available Vascular thrombosis and pregnancy morbidity represent the clinical manifestations of antiphospholipid syndrome (APS, which is serologically characterized by the persistent positivity of antiphospholipid antibodies (aPL. Antiplatelet and anticoagulant agents currently provide the mainstay of APS treatment. However, the debate is still open: controversies involve the intensity and the duration of anticoagulation and the treatment of stroke and refractory cases. Unfortunately, the literature cannot provide definite answers to these controversial issues as it is flawed by many limitations, mainly due to the recruitment of patients not fulfilling laboratory and clinical criteria for APS. The recommended therapeutic management of different aPL-related clinical manifestations is hereby presented, with a critical appraisal of the evidence supporting such approaches. Cutting edge therapeutic strategies are also discussed, presenting the pioneer reports about the efficacy of novel pharmacological agents in APS. Thanks to a better understanding of aPL pathogenic mechanisms, new therapeutic targets will soon be explored. Much work is still to be done to unravel the most controversial issues about APS management: future studies are warranted to define the optimal management according to aPL risk profile and to assess the impact of a strict control of cardiovascular risk factors on disease control.

Pulmonary arterial hypertension (PAH) is a severe condition causing significant morbidity and mortality in patients with systemic sclerosis (SSc). Despite the use of specific treatments, SSc-PAH survival remains poorer than in idiopathic PAH (IPAH). Recent therapeutic advances in PAH show a lower magnitude of response in SSc-PAH and a higher risk of adverse events, as compared to IPAH. The multifaceted underlying mechanisms and the multisystem nature of SSc probably explain part of the worse outcomes in SSc-PAH compared to IPAH. This review describes the current management of SSc-PAH with an emphasis on the impact of the different organ involvements in the prognosis and treatment response. An earlier detection of PAH and a better characterization of the clinical phenotypes of SSc-PAH are warranted in clinical practice and future trials. Determinants of prognosis, surrogate markers of clinical improvement or worsening, and relevance of the common endpoints used in clinical trials should be evaluated in this specific population. A multidisciplinary approach in expert referral centers is mandatory for SSc-PAH management.

Advances in treatment strategies together with an earlier diagnosis have considerably increased the average survival of cancer patients over the last four decades. Nevertheless, despite the growing number of new antineoplastic agents introduced each year, there is still no adequate therapy for problematic malignancies such as pancreatic, lung and stomach cancers. Consequently, it is important to ensure that existing drugs used to treat other types of cancers, and potentially other diseases, are not overlooked when searching for new chemotherapy regimens for these problematic cancer types. We describe a screening approach that identifies chemotherapeutics for the treatment of lung and pancreatic cancers, based on drugs already approved for other applications. Initially, the 1280 chemically and pharmacologically diverse compounds from the Prestwick Chemical Library® (PCL) were screened against A549 (lung cancer) and PANC-1 (pancreatic carcinoma) cells using the PrestoBlue fluorescent-based cell viability assay. More than 100 compounds from the PCL were identified as hits in one or both cell lines (80 of them, being drugs used to treat diseases other than cancer). Selected PCL hits were further evaluated in a dose-response manner. Promising candidates for repositioning emanating from this study include antiparasitics, cardiac glycosides, as well as the anticancer drugs vorinostat and topotecan.
Full Text Available The incidence of malignant melanoma is increasing. The majority of patients are diagnosed in early stages when the disease is highly curable. However, the more advanced or metastatic cases have always been a challenge for clinicians. The poor prognosis for patients with melanoma is now changing as numerous of promising approaches have appeared recently. The discovery of aberrations of pathways responsible for intracellular signal transduction allowed us to introduce agents specifically targeting the mutated cascades. Numerous clinical studies have been conducted to improve effectiveness of melanoma treatment. From 2011 until now, the U.S. FDA has approved seven novel agents, such as BRAF-inhibitors (vemurafenib 2011, dabrafenib 2013, MEK-inhibitors (trametinib 2013, anti-PD1 antibodies (nivolumab 2014, pembrolizumab 2014, anti-CTLA-4 antibody (ipilimumab 2011, or peginterferon-alfa-2b (2011 intended to be used in most advanced cases of melanoma. Nevertheless, clinicians continue working on new possible methods of treatment as resistance to the novel drugs is a commonly observed problem. This paper is based on latest data published until the end of January 2015.

An initiative was launched to determine if contaminated groundwaters, currently treated at source by small facilities, can be transported and treated effectively by a liquid waste evaporator located in a central facility, designed to treat building effluents from reactor and laboratory drains, and decontamination activities. This paper is on the first of a two stage structured evaluation, consisting of a four-step process, namely, identification of the treatment options, identification of key performance aspects and associated measures, impact of the options on the performance aspects and an overall assessment. Six treatment options are identified for the two sources of groundwater involving transport of the waters over approximately a 3-km distance by a combination of existing and new pipelines. Five key performance aspects is assessed through a simple scoring methodology. Sensitivity of the overall scores to weighting is also assessed to demonstrate the flexibility of the approach. The paper summarizes the assessment that can lead options to arrive at the 'best' option for implementation. (author)
Full Text Available This case was carried out to compare the healing process and time for the treatment of mange in goats using a combination of Ivermectin with dexamethasone to the earlier Ivermectin with antihistaminics approach. A 3 ½ years old female Boer cross goat was presented with a complaint of crusty lesions on different parts of the body during a routine farm visit in Selangor, Malaysia. Microscopic examinations of the skin scrapes taken revealed Sarcoptes and Psoroptes sp. of mites, while hematological analysis showed slight leucocytosis, neutrophilia with left shift, monocytosis, hyperproteinemia and hyperglobulinemia. Ivermectin injection at 0.2 mg/kg subcutaneously was administered once every 2 weeks in 4 divided doses, while Dexamethasone injection at 1 mg/10 kg and multivitamin at 10 mg/kg IM for 5 days repeated at alternate weeks. Significant improvement was recorded 6 weeks after commencement of treatment and full recovery at 10 weeks. The current drug regimen proved more effective when compared with previous cases that were treated with a combination of ivermectin and antihistaminics.

Fibromyalgia is a chronic disease of unknown etiology characterized by widespread muscle pain, with occupational, familial, social, physical and psychological performance involvement. The multidisciplinary approach to the disease leads to improvement in quality of life and symptomatology. To evaluate the improvement of activities of daily living (ADL) and quality of life following a multidisciplinary intervention (Health Primary Care and Occupational Therapy). Pretest-posttest study performed with a simple random sample of 21 patients with fibromyalgia (range 16-55 years). The measurement was performed with the Barthel scale (ADL), the scale of Lawton and Brody (IADL), the FIQ questionnaire, and no standardized surveys to assess the pre and post intervention situation. An intervention on motor skills (basic motor skills, pool exercise, outdoor exercise, restructuring, occupational performance and graded activity and intervention in ADL) was performed, combining pharmacological control of their symptoms and treatment. Fibromyalgia patients are not fully satisfied with their treatment; Primary Care receives a score of 6.89, and Hospital Care 5.79, improving the Barthel, Lawton and Brody and FIQ indexes, being statistically significant (p<.05). After the combined procedure the number of independent women in ADL and IADL increases. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

Unipolar major depressive disorder is a common, disabling, and costly disease that is the leading cause of ill health, early death, and suicide in the United States. Primary care doctors, in particular family physicians, are the first responders in this silent epidemic. Although more than a dozen different antidepressants in 7 distinct classes are widely used to treat depression in primary care, there is no evidence that one drug is superior to another. Comparative effectiveness studies have produced mixed results, and no specialty organization has published recommendations on how to choose antidepressants in a rational, evidence-based manner. In this article we present the theory and evidence for an individualized, patient-centered treatment model for major depression designed around a targeted symptom cluster-based approach to antidepressant selection. When using this model for healthy adults with major depressive disorder, the choice of antidepressants should be guided by the presence of 1 of 4 common symptom clusters: anxiety, fatigue, insomnia, and pain. This model was built to foster future research, provide a logical framework for teaching residents how to select antidepressants, and equip primary care doctors with a structured treatment strategy to deliver optimal patient-centered care in the management of a debilitating disease: major depressive disorder.

Objective: To investigate the clinical features and treatment strategy of dissymmetric bilateral frontal contusion,and to summarize our experience in treating these patients by minimally invasive surgery.Methods: Over the past 3 years,we have treated a total of 31 patients with dissymmetric bilateral frontal contusion using endoscopy-assisted unilateral cerebral falx incision.Other 30 patients treated by routine bilateral approaches within the same period were taken as control.Results: Seventeen cases (54.8％) in the unilateral operation group survived and were in good condition,8 (25.8％) had moderate disability,4 (12.9％) had severe disability,1 (3.2％) was in vegetative state,and 1 (3.2％) died.Compared with the control group,the Glasgow Outcome Scale score was not significantly different in the unilateral operation group,but the operation time,blood transfusion volume,the length of hospital stay,the incidences of mental disorder and olfactory nerve injury were greatly reduced in the unilateral operation group.Conclusions: Endoscopy-assisted unilateral cerebral falx incision can shorten the operation time,reduce surgical trauma and complications in treatment of patients with dissymmetric bilateral frontal contusion.It can obviously diminish the chance of delayed intracerebral hematoma and subsequently minimize the incidences of subfalcial and centrencephalic herniation.

Keloid therapy remains a great challenge for plastic surgeons, especially when the defect cannot be closed primarily, necessitating tissue transplantation. Here, we introduce a new treatment modality, called the sandwich therapy, for presternal keloids; the sandwich therapy incorporates preradiotherapy, superficial circumflex iliac artery perforator (SCIP) flap transplantation, and postradiotherapy. From December 2012 to October 2013, 12 patients received the "sandwich therapy." For the protocol, all patients went through 5 days of specific events: the precut procedure, preradiotherapy, resection and SCIP flap transplantation, donor site radiotherapy, and final presternal radiotherapy. All the flaps survived completely. No complication was observed during the perioperative period. With a mean follow-up of 12 months, only 1 case was reported with an incisional hypertrophic scar. In all patients, the main discomfort complaints were resolved postoperatively. A low-tension or without-tension closure could be achieved with SCIP flap transplantation. The perioperative radiotherapy could further lower the risk of keloid recurrence. The sandwich therapy provides a new surgical approach to presternal keloid treatment.

Catatonia is an infrequent but severe condition in young people. Organic diseases may be associated and need to be investigated though no specific recommendations and guidelines are available. We extensively reviewed the literature of all the cases of organic catatonia in children and adolescents from January 1969 to June 2007. We screened socio-demographic characteristics, organic diagnosis, clinical characteristics and treatment. We found 38 cases of children and adolescents with catatonia due to an organic condition. The catatonic syndrome occurred in 21 (57%) females and 16 (43%) males. The mean age of patients was 14.5 years (+/-3.39) [range=7-18 years], and three died from their condition. The organic conditions included infectious diseases (N=10), neurological conditions (N=10), toxic induced states (N=12) and genetic conditions including inborn errors of metabolism (N=6). The onset was dominantly acute, and the clinical presentation most frequently stuporous. Although benzodiazepines were recommended as primary symptomatic treatment, they were rarely prescribed. In several cases, therapeutic approach was related to organic cause (e.g., plasma exchange in lupus erythematosus; copper chelators in Wilson's disease). Based on this review and on our own experience of catatonia in youth, we proposed a consensual and multidisciplinary diagnostic strategy to help practitioners to identify underlying organic diseases.

Full Text Available Chronic abdominal visceral pain (CAVP has a significant clinical impact and represents one of the most frequent and debilitating disorders in the general population. It also leads to a significant economic burden due to workdays lost, reduced productivity, and long-term use of medications with their associated side effects. Despite the availability of several therapeutic options, the management of patients with CAVP is often inadequate, resulting in frustration for both patients and physicians. This may in part be explained by the lack of understanding of the mechanisms underlying chronic pain; in contrast with acute pain in which the pathophysiology is relatively well known and has several satisfactory therapeutic options. Recently, the development of tools for brain investigation, such as functional magnetic resonance imaging, has provided new insights on the pathophysiology of chronic pain. These new data have shown that plastic changes in the central and peripheral nervous system might play an important role in the maintenance of chronic pain. Therefore, approaches aimed at the modulation of the nervous system, rather than the ones interfering with the inflammatory pathways, may be more effective for chronic pain treatment. We propose that noninvasive central nervous system stimulation, with transcranial magnetic stimulation (TMS, might be a novel therapeutic option for CAVP. This paper will present an overview of the pathophysiology and the available therapies for CAVP, focusing on the recent advances in the treatment of this pathology.

Full Text Available Aim. To present an up-to-date algorithm incorporating recent advances regarding its diagnosis and treatment. Method. A Medline/Pubmed search was performed to identify relevant studies published in English from 1990 until 2008. Only clinical studies were identified and were used as basis for the diagnostic algorithm. Results. The eligible literature provided only observational evidence. The vast majority of neck nodes from occult primaries (>90% represent SCC with a high incidence among middle aged man. Smoking and alcohol abuse are important risk factors. Asiatic and North African patients with neck node metastases are at risk of harbouring an occult nasopharyngeal carcinoma. The remainder are adenocarcinoma, undifferentiated carcinoma, melanoma, thyroid carcinoma and Merkel cell carcinoma. Fine needle aspiration cytology (FNAC reaches sensitivity and specificity percentages of 81% and 100%, respectively and plays an important role as the second diagnostic step after routine ENT mirror and/or endoscopic examination. FDG-PET/CT has proven to be helpful in identifying occult primary carcinomas of the head and neck, especially when applied as a guiding tool prior to panendoscopy, and may induce treatment related clinical decisions in up to 60% of cases. Conclusion. Although reports on the diagnostic process offer mainly descriptive studies, current information seems sufficient to formulate a diagnostic algorithm to contribute to a more systematic diagnostic approach preventing unnecessary steps.

Full Text Available This paper presents the treatment results of 75 patients with primary hyperparathyroidism (PHPT caused by a solitary parathyroid adenoma (SPA. Patients in Group 1 had PHPT with concomitant diseases of the thy roid gland (TG. Group 2 consisted of patients with PHPT without thyroid disease. Group 3 included patients with PHPT and concurrent diseases of the parathyroid glands (PG and thyroid gland, which were operated on without the use of the proposed integrated approach. Patients in groups 1 and 2 were operated on using the following techniques. Patients in group 1 underwent surgery usinga traditional incision with photodynamic visualization (PV of the PG and exposure of the recur rent and superior laryngeal nerves (LN (in some cases with the use of magnifying devices and neuromyog raphy. Patients in group 2 underwent surgery with minimally invasive access, utilizingendoscopic video devices and the universal retractor “Multifiks1”. During the intervention,PVof the PG and electrophysiolog ical monitoring (EMof the recurrent LN were carried out. In groups 1 and 2, adequacy of the operationwas determined by the change in the level of intraoperative parathyroid hormone (PTH and ionized calcium before and after the removal of the PG. Our proposed integrated method for the treatment of patients with PHPT allowed for a significant reduction in the risk of postoperative complications and consequently an improvement in quality of life.

The Idaho National Engineering and Environmental Laboratory (INEEL) produces incinerator flyash and bottom ash as a consequence of burning low-level radioactive waste materials at the Waste Experimental Reduction Facility (WERF). The incineration process greatly reduces original waste volumes but concentrates the metals that are present, such as toxic metals (most notably cadmium, lead, and antimony) and nuisance metals (e.g., zinc). Anion species also become predominant in flyash produced by INEEL incineration, where chloride and sulfate are at concentrations that can approach 15-20 wt% each. In addition, treatment of the WERF flyash is further complicated by a significant fraction of ignitables composed of carbon soot and various hydrocarbon species that have been measured in some cases at 30% net by Loss-on-Ignition tests. Bottom ash produced at the WERF site is generally much less toxic, if not nontoxic, as compared to the flyash. Due to the complex composition of the flyash material, stabilization attempts at the INEEL have been only partly successful, causing the effectiveness and viability of treatment methods to be revisited. Breakthroughs in flyash stabilization came in 1998 when more complete characterization data gave us further insight into the chemical and physical nature of the flyash. These breakthroughs were also facilitated by the use of a computer model for electrolytes that allowed us to simulate stabilization options prior to started laboratory studies. This paper summarizes efforts at the INEEL, spanning the past three years, that have focused on stabilizing flyash. A brief history of INEEL treatability studies is given, showing that the degree of effective flyash stabilization was proportional to the amount of meaningful characterization data that was available. Various binders have been used in these treatability studies, including Portland cement type I/II, Portland cement type V, JGC Super Cement (blast furnace slag cement), a Fluid Tech

For many years all patients with dysphonia referred to in the literature as resulting from non-organic (functional) voice disorders were sent to speech therapy. Medical diagnoses were not taken into account. In our earlier Cochrane review on vocal cord nodules we discovered that evidence-based research in the area of benign voice disorders with dysphonia, and with or without slight benign swellings including nodules on the vocal cords, was lacking at that time. Therefore, a prospective randomised pilot study based on our Cochrane review has been made on dysphonic patients with non-organic (function provoked?) voice disorders as the basis for further evidence-based studies. Medical treatment was based on the scientific approach that once a micro-organic disorder caused by reflux, infection, allergy or environmental irritatants (e.g., dust or noise in the workplace) was discovered by very careful anamnesis and systematic objective routine analyses and was treated effectively, with documentation, the non-organic voice disorder disappeared, as, e.g., in the case of a diagnosis and treatment of helicobakter pylori. The reason is that the mucosal swelling/dysfunction of the vocal cords is secondary. In order to try to understand why the recommendation to all these patients for many years was only voice therapy, which the speech therapists "felt to be effective", updated voice-hygiene advice (for posture, accents of the diaphragm, intonation pattern and resonance) was given by experienced laryngologists, randomised with the updated medical diagnosis/therapy in order to elucidate what effect the training might have. No evidence-based studies in the literature document any effect. The crucial point seemed to be that doctors mostly did not examine any other diagnoses other than the "dysphonia" and did not dig down to any of the medical reasons when the vocal fold diagnosis of "non- organic disorders" was made. This should be changed in the future. This pilot study was based

Purpose In acute myeloid leukemia (AML), initial treatment response by morphologic analysis of bone marrow predicts long-term outcome. Response can now be assessed by minimal residual disease (MRD) monitoring with flow cytometry or polymerase chain reaction (PCR). We determined the relation among the results of these approaches and their prognostic value. Patients and Methods In the multicenter AML02 study, follow-up bone marrow samples from 203 children and adolescents with newly diagnosed AML were examined by flow cytometry (n = 1,514), morphology (n = 1,382), and PCR amplification of fusion transcripts (n = 508). Results were correlated with treatment outcome. Results Among 1,215 samples with less than 5% leukemic myeloblasts by morphology, 100 (8.2%) were MRD positive (≥ 0.1%) by flow cytometry, whereas 96 (57.5%) of the 167 samples with ≥ 5% blasts were MRD negative. Virtually all (308 of 311; 99.0%) MRD-negative samples by PCR were also MRD negative by flow cytometry. However, only 19 (9.6%) of the 197 PCR-positive samples were flow cytometry positive, with analyses of AML1-ETO and CBFβ-MYH11 accounting for most discrepancies, whereas eight of 13 MLL-positive samples had detectable MRD by flow cytometry. MRD by flow cytometry after induction 1 or 2 predicted lower event-free survival and higher relapse rate (P < .001) and was an independent prognostic factor in a multivariable analysis; prediction was not improved by morphologic information or molecular findings. Conclusion In childhood AML, morphologic assessment of treatment response has limited value if MRD is measured by flow cytometry. MLL fusion transcripts can provide prognostic information in some patients, whereas monitoring of AML1-ETO and CBFβ-MYH11 transcripts is largely uninformative. PMID:22965955
Full Text Available Abstract Objective Sulfur mustard (SM is one of the major potent chemical warfare and attractive weapons for terrorists. It has caused deaths to hundreds of thousands of victims in World War I and more recently during the Iran-Iraq war (1980–1988. It has ability to develop severe acute and chronic damage to the respiratory tract, eyes and skin. Understanding the acute and chronic biologic consequences of SM exposure may be quite essential for developing efficient prophylactic/therapeutic measures. One of the systems majorly affected by SM is the respiratory tract that numerous clinical studies have detailed processes of injury, diagnosis and treatments of lung. The low mortality rate has been contributed to high prevalence of victims and high lifetime morbidity burden. However, there are no curative modalities available in such patients. In this review, we collected and discussed the related articles on the preventive and therapeutic approaches to SM-induced respiratory injury and summarized what is currently known about the management and therapeutic strategies of acute and long-term consequences of SM lung injuries. Method This review was done by reviewing all papers found by searching following key words sulfur mustard; lung; chronic; acute; COPD; treatment. Results Mustard lung has an ongoing pathological process and is active disorder even years after exposure to SM. Different drug classes have been studied, nevertheless there are no curative modalities for mustard lung. Conclusion Complementary studies on one hand regarding pharmacokinetic of drugs and molecular investigations are mandatory to obtain more effective treatments.

In this review, we collected and discussed the related articles on the preventive and therapeutic approaches to SM-induced respiratory injury and summarized what is currently known about the management and therapeutic strategies of acute and long-term consequences of SM lung injuries.Method:This review was done by reviewing all papers found by searching following key words sulfur mustard; lung; chronic; acute; COPD; treatment.Results:Mustard lung has an ongoing pathological process and is active disorder even years after exposure to SM. Different drug classes have been studied, nevertheless there are no curative modalities for mustard lung. Conclusion:Complementary studies on one hand regarding pharmacokinetic of drugs and molecular investigations are mandatory to obtain more effective treatments.

The goal of the present study was to evaluate the outcome of risk-adapted planning treatment volumes (PTVs) in patients with cervical lymph node metastases of unknown primary cancer (UPC) treated with intensity-modulated radiotherapy (IMRT). Between January 2006 and November 2012, 28 patients with cervical lymph node metastases of UPC were treated in our institution with IMRT either postoperatively (n=20) or as definitive treatment (n=8). Nodal involvement distributed as follows: N1 (n=2), N2a (8), N2b (10), N2c (4), and N3 (4). Systemic therapy with cisplatin or cetuximab was added concomitantly in 20 of 28 patients (71%). Radiotherapy using simultaneously integrated boost (SIB-IMRT) was carried out with 2.0 or 2.11 Gy single doses up to 66/70 Gy. Mean/median follow-up was 31.6/30.5 months (range 3-78 months). In all, 15 of 28 patients were treated with unilateral SIB-IMRT (54%). An elective PTV to the contralateral oropharynx and contralateral level II-III lymph nodes was carried out in 8 patients with PET-CT suspected but not histologically proven involvement, recurrences or former tumor of the oropharynx. More extended treatment fields were reserved for patients with N2c or bilaterally N3 status (n=5). The 3-year overall survival, mucosal control, neck control and distant metastasis-free survival rates were 76, 100, 93, and 88%, respectively. No patient suffered from a locoregional recurrence. Two patients treated with radiotherapy alone had persistent nodal disease. No grade II or higher late sequel has been observed. Our single center approach to treat patients with cervical lymph node metastases of UPC with individualized, risk-adapted SIB-IMRT resulted in high locoregional tumor control and was well tolerated.

The aim of this study is to use the life cycle assessment method to measure the environmental performance of the sludge incineration process in a wastewater treatment plant and to propose an alternative that can reduce the environmental impact. To show the damages caused by the treatment processes, the study aimed to use an endpoint approach in evaluating impacts on human health, ecosystem quality, and resources due to the processes. A case study was taken at Bissell Point Wastewater Treatment Plant in Saint Louis, Missouri, U.S. The plant-specific data along with literature data from technical publications were used to build an inventory, and then analyzed the environmental burdens from sludge handling unit in the year 2011. The impact assessment method chosen was ReCipe 2008. The existing scenario (dewatering-multiple hearth incineration-ash to landfill) was evaluated and three alternative scenarios (fluid bed incineration and anaerobic digestion with and without land application) with energy recovery from heat or biogas were proposed and analyzed to find the one with the least environmental impact. The existing scenario shows that the most significant impacts are related to depletion in resources and damage to human health. These impacts mainly came from the operation phase (electricity and fuel consumption and emissions related to combustion). Alternatives showed better performance than the existing scenario. Using ReCipe endpoint methodology, and among the three alternatives tested, the anaerobic digestion had the best overall environmental performance. It is recommended to convert to fluid bed incineration if the concerns were more about human health or to anaerobic digestion if the concerns were more about depletion in resources. The endpoint approach may simplify the outcomes of this study as follows: if the plant is converted to fluid bed incineration, it could prevent an average of 43.2 DALYs in human life, save 0.059 species in the area from extinction

Electroporation-based applications require multidisciplinary expertise and collaboration of experts with different professional backgrounds in engineering and science. Beginning in 2003, an international scientific workshop and postgraduate course electroporation based technologies and treatments (EBTT) has been organized at the University of Ljubljana to facilitate transfer of knowledge from leading experts to researches, students and newcomers in the field of electroporation. In this paper we present one of the integral parts of EBTT: an e-learning practical work we developed to complement delivery of knowledge via lectures and laboratory work, thus providing a blended learning approach on electrical phenomena involved in electroporation-based therapies and treatments. The learning effect was assessed via a pre- and post e-learning examination test composed of 10 multiple choice questions (i.e. items). The e-learning practical work session and both of the e-learning examination tests were carried out after the live EBTT lectures and other laboratory work. Statistical analysis was performed to compare and evaluate the learning effect measured in two groups of students: (1) electrical engineers and (2) natural scientists (i.e. medical doctors, biologists and chemists) undergoing the e-learning practical work in 2011-2014 academic years. Item analysis was performed to assess the difficulty of each item of the examination test. The results of our study show that the total score on the post examination test significantly improved and the item difficulty in both experimental groups decreased. The natural scientists reached the same level of knowledge (no statistical difference in total post-examination test score) on the post-course test take, as do electrical engineers, although the engineers started with statistically higher total pre-test examination score, as expected. The main objective of this study was to investigate whether the educational content the e

The current open trial evaluated an inference-based approach (IBA) to the treatment of obsessive-compulsive disorder (OCD) across symptom subtypes and treatment-resistant cases. Following formal diagnosis through semi-structured interview by an independent evaluator, a total of 125 OCD participants across five major symptom subtypes entered a program of 24 sessions of treatment based on the IBA. An additional group of 22 participants acted as a natural wait-list control group. Participants were administered the Yale-Brown Obsessive-Compulsive Scale before and after treatment as the principal outcome measure, as well as measures of negative mood states, inferential confusion and obsessive beliefs. Level of overvalued ideation was assessed clinically at pre-treatment using the Overvalued Ideation Scale. After 24 weeks of treatment, 102 treatment completers across all major subtypes of OCD showed significant reductions on the Yale-Brown Obsessive-Compulsive Scale with effect sizes ranging from 1.49 to 2.53 with a clinically significant improvement in 59.8% of participants. No improvement was observed in a natural wait-list comparison group. In addition, IBA was effective for those with high levels of overvalued ideation. Change in inferential confusion and beliefs about threat and responsibility were uniquely associated with treatment outcome. The study is the first large-scale open trial showing IBA to be effective across symptom subtypes and treatment-resistant cases. The treatment may be particularly valuable for those who have previously shown an attenuated response to other treatments. Copyright © 2016 John Wiley & Sons, Ltd. Psychological treatment based on the inference-based approach is an effective treatment for all major subtypes of obsessive-compulsive disorder. The treatment is equally effective for those with high and low levels of overvalued ideation. Treatment based on the inference-based approach may be particularly valuable for those who have shown

Treatments of pediatric feeding disorders based on applied behavior analysis (ABA) have the most empirical support in the research literature (Volkert & Piazza, 2012); however, professionals often recommend, and caregivers often use, treatments that have limited empirical support. In the current investigation, we compared a modified sequential oral sensory approach (M-SOS; Benson, Parke, Gannon, & Muñoz, 2013) to an ABA approach for the treatment of the food selectivity of 6 children with autism. We randomly assigned 3 children to ABA and 3 children to M-SOS and compared the effects of treatment in a multiple baseline design across novel, healthy target foods. We used a multielement design to assess treatment generalization. Consumption of target foods increased for children who received ABA, but not for children who received M-SOS. We subsequently implemented ABA with the children for whom M-SOS was not effective and observed a potential treatment generalization effect during ABA when M-SOS preceded ABA.

MRI significantly improves the accuracy and reliability of target delineation in radiation therapy for certain tumors due to its superior soft tissue contrast compared to CT. A treatment planning process with MRI as the sole imaging modality will eliminate systematic CT/MRI co-registration errors, reduce cost and radiation exposure, and simplify clinical workflow. However, MRI lacks the key electron density information necessary for accurate dose calculation and generating reference images for patient setup. The purpose of this work is to develop a unifying method to derive electron density from standard T1-weighted MRI. We propose to combine both intensity and geometry information into a unifying probabilistic Bayesian framework for electron density mapping. For each voxel, we compute two conditional probability density functions (PDFs) of electron density given its: (1) T1-weighted MRI intensity, and (2) geometry in a reference anatomy, obtained by deformable image registration between the MRI of the atlas and test patient. The two conditional PDFs containing intensity and geometry information are combined into a unifying posterior PDF, whose mean value corresponds to the optimal electron density value under the mean-square error criterion. We evaluated the algorithm’s accuracy of electron density mapping and its ability to detect bone in the head for eight patients, using an additional patient as the atlas or template. Mean absolute HU error between the estimated and true CT, as well as receiver operating characteristics for bone detection (HU > 200) were calculated. The performance was compared with a global intensity approach based on T1 and no density correction (set whole head to water). The proposed technique significantly reduced the errors in electron density estimation, with a mean absolute HU error of 126, compared with 139 for deformable registration (p = 2 × 10-4), 283 for the intensity approach (p = 2 × 10-6) and 282 without density

More recently, the combination of BRAF inhibitor dabrafenib with MEK inhibitor trametinib has shown improved progression-free survival, compared to dabrafenib monotherapy, in a Phase II study and has received approval by the US Food and Drug Administration. However, even when treated with the combination, most patients develop mechanisms of acquired resistance, and some of them do not achieve tumor regression at all, because of intrinsic resistance to therapy. Along with the development of BRAF inhibitors, immunotherapy made an important step forward: ipilimumab, an anti-CTLA-4 monoclonal antibody, was approved for the treatment of metastatic melanoma; anti-PD-1 agents achieved promising results in Phase I/II trials, and data from Phase III studies will be ready soon. The availability of such drugs, which are effective regardless of BRAF status, has made the therapeutic approach more complex, as first-line treatment with BRAF inhibitors may not be the best choice for all BRAF-mutated patients. The aim of this paper is to review the systemic therapeutic options

Drug development in Systemic Lupus Erythematosus (SLE) has been hindered by poor translation from successful preclinical experiments to clinical efficacy. This lack of success has been attributed to the high heterogeneity of SLE patients and to the lack of understanding of disease physiopathology. Modelling approaches could be useful for supporting the identification of targets, biomarkers and patient subpopulations with differential response to drugs. However, the use of traditional quantitative models based on differential equations is not justifiable in a sparse data situation. Boolean networks models are less demanding on the required data to be implemented and can provide insights into the dynamics of biological networks. This methodology allows the integration of all the available knowledge into a single framework to evaluate the behavior of the system under different conditions and test hypotheses about unknown aspects of the disease. In this proof-of-concept study, we explored the potential of a systems pharmacology model based on Boolean networks to support drug development in SLE. We focused the analysis on the antigen presentation by the antigen presenting cells (APC) to the T-cells to evaluate the scope of this methodology in a medium size network before full implementation of the whole SLE pathway. The heterogeneity of SLE patients was replicated using this methodology simulating subjects with distinct pathway alterations. A perturbation analysis of the network coupled with clustering analysis showed potential to identify drug targets, optimal combinatorial regimens and subpopulations of responders and non-responders to drug treatment. We propose this approach as a first step towards the development of more quantitative platforms to address the current challenges in drug development for complex diseases.
Full Text Available Introduction. Risk stratification is nowadays crucial when estimating the patient’s prognosis in terms of treatment outcome and it also helps in clinical decision making. Several risk assessment models have been developed to predict short-term outcomes in patients with acute coronary syndrome. This study was aimed at developing an outcome prediction model for patients with acute coronary syndrome submitted to percutaneus coronary intervention using data mining approach. Material and Methods. A total of 2030 patients hospitalized for acute coronary syndrome and treated with percutaneous coronary intervention from December 2008 to December 2011 were assigned to a derivation cohort. Demographic and anamnestic data, clinical characteristics on admission, biochemical analysis of blood parameters on admission, and left ventricular ejection fraction formed the basis of the study. A number of machine learning algorithms available within Waikato Environment for Knowledge Discovery had been evaluated and the most successful was chosen. The predictive model was subsequently validated in a different population of 931 patients (validation cohort, hospitalized during 2012. Results. The best prediction results were achieved using Alternating Decision Tree classifier, which was able to predict in-hospital mortality with 89% accuracy, and preserved good performance on validation cohort with 87% accuracy. Alternating Decision Tree classifier identified a subset of 6 attributes most relevant to mortality prediction: systolic and diastolic blood pressure, heart rate, left ventricular ejection fraction, age, and troponin value. Conclusion. Data mining approach enabled the authors to develop a model capable of predicting the in-hospital outcome following percutaneous coronary intervention. The model showed excellent sensitivity and specificity during internal validation.

Haglund syndrome is characterized by chronic posterior heel pain associated with a posterosuperior calcaneal prominence. We assessed the clinical and radiologic outcomes after operative treatment of Haglund syndrome using the central tendon-splitting approach. Fifteen feet in 15 patients were investigated retrospectively after surgery. Of the 15 patients, 14 were males (93.3%) and 1 was female (6.7%). Their mean age was 33.1 ± 8.2 (range 20 to 50) years. The mean follow-up duration was 3.5 ± 1.5 years (range 24 to 90 months). The American Orthopaedic Foot and Ankle Society ankle-hindfoot Scale and Victorian Institute of Sport Assessment-Achilles scores were investigated to assess the clinical outcomes. Patient satisfaction was assessed at the latest follow-up visit. The lateral talo-first metatarsal angle, calcaneal pitch angle, Fowler-Philip angle, and parallel pitch line were measured to assess the foot shape and radiographic outcomes. Clinically, the mean American Orthopaedic Foot and Ankle Society ankle-hindfoot scale score increased from 62.1 ± 7.5 preoperatively to 92.5 ± 3.5 at the latest follow-up visit. The mean Victorian Institute of Sport Assessment-Achilles score increased from 53.2 ± 7.4 to 89.6 ± 3.4. All patients were satisfied with the operative results. Radiographically, all patients had cavus feet with an increased lateral talo-first metatarsal angle (mean +5.9° ± 5.0°) and calcaneal pitch angle (mean 26.0° ± 3.8°). The mean Fowler-Philip angle decreased from 58.9° ± 15.0° to 32.5° ± 7.2° postoperatively, and the positive parallel pitch line had changed to a negative value in all cases. Operative treatment with the central tendon-splitting approach appears to be safe and satisfactory for intractable Haglund syndrome.

In Mali, there were 4508 new cases of tuberculosis in 2003, and 5222 in 2006. Tuberculosis (TB) is thus an important public health problem, decreasing the physical, financial and social capital of individuals, their families and society. Because responses to TB have not yet applied a sufficiently integrated approach that can improve patients' access to quality care, this FORESA project advocates a patient-centered approach. Before any intervention, FORESA thus sought to analyse the situation of TB in Mali and responses to it. The study aims to analyse the discourse about and popular representations of TB (its forms, its signs), the situations in which people are exposed to it or transmit it, and popular practices related to its prevention and the experience of having it. This qualitative, descriptive and analytical study includes a literature review, in-depth interviews with opinion leaders, community health workers and TB patients, focus groups, and the observations of practices. The interviews were recorded, transcribed, and analysed. Subjects provided informed consent to participation. This study showed that: * the terms for TB in local languages (Bambara, Dogon and Fulfuldé) include white cough, big cough, and long cough; * These communities differentiate between 2 main forms of cough (simple and wet); * TB is perceived as a transmissible disease, a disease of contact with a contaminated body or objects; * TB is seen as a serious, contagious, hereditary, shameful disease that may result from the transgression of social norms; * The prevention of TB consists of avoiding people who have the disease or transmitting factors; * Therapeutic remedies, in order, are self-medication, the use of traditional healers, and finally visits to health centres; * The population wants more information about TB and be involved in the fight against it. This study shows the many points of convergence about TB nosology, etiology and therapy between the Mopti population and other

At this time, other than parathyroid hormone analogs, all therapies for osteoporosis are antiresorptive. Therefore, researchers have focused efforts on development of more anabolic therapies. Understanding of the Wnt signaling pathway, which is critical for skeletal development, and the role of sclerostin in inhibition of Wnt signaling has led to the discovery of a novel therapeutic approach in the treatment of osteoporosis – sclerostin inhibition. In this review, we discuss the biology of Wnt signaling and sclerostin inhibition. We then discuss human disorders of decreased sclerostin function and animal models of sclerostin inhibition. Both have served to elucidate the effects of decreased sclerostin levels and function – increased bone mass and strength and fewer fractures. In addition, we review data from Phase I and II studies of the two humanized sclerostin monoclonal antibodies, romosozumab and blosozumab, both of which have had positive effects on bone mineral density. We conclude with a discussion of the ongoing Phase III studies of romosozumab. The available data support the potential for neutralizing sclerostin monoclonal antibodies to serve as anabolic agents in the treatment of osteoporosis. Keywords: osteoporosis, sclerostin, Wnt signaling, anabolic therapies, romosozumab
Full Text Available Abstract Background Infections caused by hepatitis B virus (HBV and hepatitis C virus (HCV are considered to be important health problems worldwide. The purpose of this study was to measure the general practitioners (GPs' basic knowledge on HBV and HCV risk factors in determining their practice about this subject. Methods A cross-sectional type questionnaire survey was carried out at all of 32 primary healthcare centers (PHCCs in Samsun, Turkey, between March 1 and April 31, 2002. The questionnaires were sent to 160 GPs and 129 (80.6% of them answered the questionnaires. Knowledge, role responsibility, self-efficacy and attitudes and beliefs regarding to viral hepatitis B and hepatitis C were asked. Results Most of the GPs had adequate knowledge about transmission of HBV and HCV and also about risk factors for transmission of viruses. Most of the GPs (83.7% were aware of recommendations for approach to a baby, born from HBsAg positive mother. They have limited facilities in diagnosis of viral hepatitis. Of the participants, 108 (83.7% expressed that they could not diagnose HBV infections and 126 (97.7% of them stated that they could not make the diagnoses of HCV infection in their local healthcare centers. The knowledge about treatment of chronic viral hepatitis B (21.8% and C patients (17.8% with elevated ALT is not sufficient. Conclusion GPs' knowledge about risks of viral hepatitis was adequate in this study. They were not able to diagnose and follow up of these infections at PHCCs because of limited knowledge about chronic viral hepatitis and diagnostic facilities. GPs should be informed about current advice in diagnosis and treatment of chronic of HBV and HCV infections.
Full Text Available Background: Treatment of humeral shaft fractures has been a subject of debate for many decades. Even though a large majority of humeral shaft fractures can be treated by non operative methods, few conditions like open fractures, polytrauma, ipsilateral humeral shaft and forearm fractures require surgical intervention. The goal of treatment of humeral shaft fractures is to establish union with an acceptable humeral alignment and to restore the patient to pre-injury level of function. The objective was to assess the incidence of radial nerve palsy, non-union and mean time required for in anteromedial plate osteosynthesis with anterolateral approach and also to measure the functional outcome of this procedure. Method: A prospective study was conducted in the Department of Orthopaedics, PESIMSR, Kuppam, Andhra Pradesh, from August 2012 to August 2015 with a total of 54 patients who were operated with anteromedial plate osteosynthesis were included in the study. RodriguezMerchan criteria was used to grade the functional outcome. Results: Of the 54 patients, 28 (58.85% were in the age group of 30-40 years. The most common fracture pattern identified was A3 type (48.14%.The mean (+ SD duration of surgery for anteromedial humeral plating was 53 ± 5.00 minutes. The time taken for the fracture to unite was less than 16 weeks in the majority or 50 patients (92.59%. Four (7.40% patients had delayed union. There was no incidence of iatrogenic radial nerve palsy. Rodriguez – Merchan criteria showed that 37(68.51% of the patients had good and 12 (22.22% had excellent functional outcome.

Background: Single-pill combinations of aliskiren/hydrochlorothiazide have recently been approved by the European Medicines Agency for the treatment of hypertension. Objective: This study aimed to assess the antihypertensive efficacy of aliskiren/hydrochlorothiazide combination in reducing systolic and diastolic blood pressure in hypertensive patients. Methods: A search in International Pharmaceutical Abstracts, MEDLINE, The Cochrane Library and ISI Web of Knowledge was performed from 2000 to November 2009, to identify randomized, double-blind, clinical trials using aliskiren/hydrochlorothiazide for the treatment of hypertension. Studies were included if they evaluated the antihypertensive efficacy of aliskiren/hydrochlorothiazide in patients with mild or moderate essential hypertension and age ≥ 18 years. The meta-analytical approach calculated the weighted average reductions of systolic and diastolic blood pressure for each daily dosage combination. Results: We included 5 clinical trials testing several combinations of aliskiren/hydrochlorothiazide and containing data on 5448 patients. In all studies blood pressure was assessed at inclusion (baseline) and after 8 weeks of therapy. Blood pressure reductions and control rates were significantly (p < 0.05) higher with the aliskiren/hydrochlorothiazide combinations than with placebo and the same doses of aliskiren or hydrochlorothiazide alone. The weighted mean reductions (mm Hg) from baseline of systolic and diastolic blood pressure for each aliskiren/hydrochlorothiazide combination were: -15.8/-10.3 (150/25 mg); -15.9/-11.8 (300/12.5 mg); -16.9/-11.6 (300/25 mg). Blood pressure control rates (%) for the above combinations were, at least, respectively: 43.8, 50.1 and 51.9. Conclusions: Aliskiren/hydrochlorothiazide provided clinically significant additional blood pressure reductions and improved blood pressure control rates over aliskiren or hydrochlorothiazide monotherapy.

Full Text Available BACKGROUND: Osteoporosis is the most prevalent skeletal disorder, characterized by a low bone mineral density (BMD and bone structural deterioration, leading to bone fragility fractures. Accelerated bone resorption by osteoclasts has been established as a principal mechanism in osteoporosis. However, recent experimental evidences suggest that inappropriate apoptosis of osteoblasts/osteocytes accounts for, at least in part, the imbalance in bone remodeling as occurs in osteoporosis. The aim of this study is to examine whether aspirin, which has been reported as an effective drug improving bone mineral density in human epidemiology studies, regulates the balance between bone resorption and bone formation at stem cell levels. METHODS AND FINDINGS: We found that T cell-mediated bone marrow mesenchymal stem cell (BMMSC impairment plays a crucial role in ovariectomized-induced osteoporosis. Ex vivo mechanistic studies revealed that T cell-mediated BMMSC impairment was mainly attributed to the apoptosis of BMMSCs via the Fas/Fas ligand pathway. To explore potential of using pharmacologic stem cell based intervention as an approach for osteoporosis treatment, we selected ovariectomy (OVX-induced osteoporosis mouse model to examine feasibility and mechanism of aspirin-mediated therapy for osteoporosis. We found that aspirin can inhibit T cell activation and Fas ligand induced BMMSC apoptosis in vitro. Further, we revealed that aspirin increases osteogenesis of BMMSCs by aiming at telomerase activity and inhibits osteoclast activity in OVX mice, leading to ameliorating bone density. CONCLUSION: Our findings have revealed a novel osteoporosis mechanism in which activated T cells induce BMMSC apoptosis via Fas/Fas ligand pathway and suggested that pharmacologic stem cell based intervention by aspirin may be a new alternative in osteoporosis treatment including activated osteoblasts and inhibited osteoclasts.

Fenton oxidation and ultrasound-based pretreatment have been applied to improve the treatment of real industrial wastewater based on the use of biological oxidation. The effect of operating parameters such as Fe(2+) loading, contact time, initial pH, and hydrogen peroxide loading on the extent of chemical oxygen demand (COD) reduction and change in biochemical oxygen demand (BOD5)/COD ratio has been investigated. The optimum operating conditions established for the pretreatment were initial pH of 3.0, Fe(2+) loading of 2.0, and 2.5 g L(-1) for the US/Fenton/stirring and Fenton approach, respectively, and temperature of 25 °C with initial H2O2 loading of 1.5 g L(-1). The use of pretreatment resulted in a significant increase in the BOD5/COD ratio confirming the production of easily digestible intermediates. The effect of the type of sludge in the aerobic biodegradation was also investigated based on the use of primary activated sludge (PAS), modified activated sludge (MAS), and activated sludge (AS). Enhanced removal of the pollutants as well as higher biomass yield was observed for MAS as compared to PAS and AS. The use of US/Fenton/stirring pretreatment under the optimized conditions followed by biological oxidation using MAS resulted in maximum COD removal at 97.9 %. The required hydraulic retention time for the combined oxidation system was also significantly lower as compared to only biological oxidation operation. Kinetic studies revealed that the reduction in the COD followed a first-order kinetic model for advanced oxidation and pseudo first-order model for biodegradation. The study clearly established the utility of the combined technology for the effective treatment of real industrial wastewater.

Fifty-eight patients with advanced head and neck cancer were entered into a randomised trial comparing chemotherapy (DDP + bleomycin) alone, multiple daily fractionated radiation therapy, and multimodality therapy consisting of chemotherapy plus multiple fractionated radiation therapy. Multimodal therapy gave a significantly higher response rate (69%) than either single-treatment modality. The use of a multiple daily dose fractionation allowed radiation therapy to be completed over 10 treatment days, and the addition of chemotherapy to the radiation treatment did not significantly increase toxicity. Patients receiving multimodal therapy also survived significantly longer (median 50 weeks) than those receiving single-modality therapy (median 24 weeks).

-5 days) in anterolateral group and (6.2±2.8) days (range: 3-10 days) in posterior group. No patients in anterolateral group experienced dislocation. One (5%) hip in posterior approach had dislocation.Conclusions: Anterolateral mini-invasive approach can decrease trauma, operation time, length of hospital stay and bed stay and rehabilitation time. The stability and minimal muscular damage permit the acceleration of postoperative rehabilitation, which can subsequently reduce the perioperative risk in the treatment of femoral neck fractures in the elderly undergoing total hip replacement.
Full Text Available Objective To investigate the clinical effects of bone marrow mesenchymal stem cell (BMSC transplantation via different approaches in the treatment of liver cirrhosis in mice. Methods A total of 46 BALB/c mice were randomly divided into normal control group with 5 mice and liver cirrhosis model group with 41 mice. Subcutaneously injected carbon tetrachloride olive oil was used to establish the mouse model of liver cirrhosis. A total of 36 mice with liver cirrhosis were randomly divided into control group, caudal vein BMSC transplantation group, and spleen BMSC transplantation group, with 12 mice in each group. Whole bone marrow adherent culture was performed to obtain the third-generation BMSCs, and flow cytometry was used for cell surface identification. BMSCs were injected into the mice through the caudal vein or spleen. Blood samples were collected at 4 weeks after transplantation to measure liver function. HE and Masson staining and α-smooth muscle actin (α-SMA immunohistochemistry were performed for liver sections. Liver injury and fibrosis in mice were examined. A one-way analysis of variance was used for comparison between groups. Results At 8 weeks after the establishment of the model, the mice in the model group had sparse and dark yellow hair, reduced food consumption and activity, and a reduction in body weight. After transplantation, compared with the model control group, the caudal vein BMSC transplantation group and spleen BMSC transplantation group showed a significant increase in albumin and significant reductions in alanine aminotransferase and aspartate aminotransferase (all P＜0.01. There were no significant differences between the two transplantation approaches (P＞0.05. After transplantation, there were significant changes in diseased tissue, alleviated liver cirrhosis, reduced collagen fiber and necrotic area, and a good structure. Immunohistochemistry showed both transplantation groups showed significant reductions in

New tools are being developed to estimate greenhouse gas (GHG) emissions from wastewater treatment plants (WWTPs). There is a trend to move from empirical factors to simple comprehensive and more complex process-based models. Thus, the main objective of this study is to demonstrate the importance of using process-based dynamic models to better evaluate GHG emissions. This is tackled by defining a virtual case study based on the whole plant Benchmark Simulation Model Platform No. 2 (BSM2) and estimating GHG emissions using two approaches: (1) a combination of simple comprehensive models based on empirical assumptions and (2) a more sophisticated approach, which describes the mechanistic production of nitrous oxide (N(2) O) in the biological reactor (ASMN) and the generation of carbon dioxide (CO(2) ) and methane (CH(4) ) from the Anaerobic Digestion Model 1 (ADM1). Models already presented in literature are used, but modifications compared to the previously published ASMN model have been made. Also model interfaces between the ASMN and the ADM1 models have been developed. The results show that the use of the different approaches leads to significant differences in the N(2) O emissions (a factor of 3) but not in the CH(4) emissions (about 4%). Estimations of GHG emissions are also compared for steady-state and dynamic simulations. Averaged values for GHG emissions obtained with steady-state and dynamic simulations are rather similar. However, when looking at the dynamics of N(2) O emissions, large variability (3-6 ton CO(2) e day(-1) ) is observed due to changes in the influent wastewater C/N ratio and temperature which would not be captured by a steady-state analysis (4.4 ton CO(2) e day(-1) ). Finally, this study also shows the effect of changing the anaerobic digestion volume on the total GHG emissions. Decreasing the anaerobic digester volume resulted in a slight reduction in CH(4) emissions (about 5%), but significantly decreased N(2) O emissions in

Contractures to the cervical region as a result of burns has the capacity to cause restrictions in range of movement, function of the lower face, cervical spine distortion and poor aesthetic outcomes that remain a surgical challenge. Consequently, physical and aesthetic deformities as a result of cervical contractures are reported to cause depression having implications for patients' quality of life and psychosocial wellbeing. At the time this research was conducted, there were no case reports describing a closed platysmotomy approach in burn patients. In this article, we review the literature surrounding closed platysmotomies and present what we believe to be the first reported case in the treatment of cervical contractures utilising a closed platysmotomy approach in a burns patient. A closed platysmotomy approach for the treatment of cervical contractures is a less invasive technique. Further investigation is warranted to determine the feasibility of this reconstructive approach in the area of burn scar management.
Full Text Available In our study we showed the importance of holistic approach to evaluation of chemical stabilization using phosphate amendments, where all aspects of chemical treatments were observed. An extensive evaluation of metal stabilization in contaminated soil and an evaluation of the leaching of phosphorus induced after treatment were performed. The soil from the former zinc smelter area in the Celje region, used in this study, was heavily polluted with Zn (34 400 ± 1500 mg kg−1, Pb (20 400 ± 1500 mg kg−1, As (950 ± 10 mg kg−1, Cu (549 ± 7 mg kg−1 and Cd (158 ± 4 mg kg−1. The results of Toxicity Characteristic Leaching Procedure showed high mobility of Zn (540 ± 25 mg L−1, Pb (12.7 ± 0.5 mg L−1 and Cd (2.9 ± 0.1 mg L−1. To immobilize metals in the soil, mixtures of soil with phosphate (variable molar ratio of hydroxyapatite and phosphoric acid were prepared with a constant molar Pb:P ratio of 1:10. Hydroxyapatite as the only source of phosphate showed a high stabilization efficiency, above all for Pb with over 97 % of primary acetic acid leachable Pb immobilized. The addition of phosphoric acid as a source of phosphate resulted in an increase in leaching of phosphorus up to 50 mg L−1 in water extracts. Lime that was also added in some stabilization mixtures increased the stabilization efficiency of phosphate and also decreased the treatment-induced phosphate leaching. To evaluate the long-term stability of immobilization, leaching of metals and phosphorus was assessed in a column experiment with synthetic precipitation that in general showed steady decrease in leachability of metals and phosphorus with quite high cumulative Zn and Cd concentrations in leachates of soil sample and extremely high (30% of total added P concentration cumulative P concentrations in leachates of mixture with highest amount of added phosphoric acid and no addition of lime.

Tissue engineering is the use of cultured cells seeded into biodegradable polymers to create custom designed, living implantable devices. As a first approach to the use of this technique in the treatment of hydrocephalus, we have prepared chondrocyte-seeded polyglycolic acid (PGA) tubes coated with polylactic glycolic acid (PGLA), implanted initially with thin silastic stents removed four weeks after shunt insertion. The use of bovine xenograft cells in athymic (nude) rats resulted in more efficient seeding with chondrocytes, stiffer tube walls, and better patency. When implanted in 6-week-old rats made hydrocephalic by cisternal injection of kaolin at 4 weeks of age, six of eight 'living shunts' remained patent to radio-opaque contrast injection at two weeks after stent removal. At four weeks after stent removal, all four of the shunts had occluded at the ventricular end, three of the four apparently due to growth of the animal. We conclude that polymer type, cell type, and cell density will require considerable optimization, but a working tissue engineered shunt is feasible and may one day address some problems of interactions of living tissue and inert polymer.

Full Text Available Hydrogen sulfide (H2S has been reported to exacerbate stroke outcome in experimental models. Cystathionine β-synthase (CBS has been implicated as the predominant H2S-producing enzyme in central nervous system. When SH-SY5Y cells were transfected to overexpress CBS, these cells were able to synthesize H2S when exposed to high levels of enzyme substrates but not substrate concentrations that may reflect normal physiological conditions. At the same time, these cells demonstrated exacerbated cell death when subjected to oxygen and glucose deprivation (OGD together with high substrate concentrations, indicating that H2S production has a detrimental effect on cell survival. This effect could be abolished by CBS inhibition. The same effect was observed with primary astrocytes exposed to OGD and high substrates or sodium hydrosulfide. In addition, CBS was upregulated and activated by truncation in primary astrocytes subjected to OGD. When rats were subjected to permanent middle cerebral artery occlusion, CBS activation was also observed. These results imply that in acute ischemic conditions, CBS is upregulated and activated by truncation causing an increased production of H2S, which exacerbate the ischemic injuries. Therefore, CBS inhibition may be a viable approach to stroke treatment.

Full Text Available Abstract Due to the limited supply of mental health services for Afro-Colombian victims of violence, a Common Elements Treatment Approach (CETA intervention has been implemented in the Colombian Pacific. Given the importance of improvement in mental health interventions for this population, it is necessary to characterize this process. This article seeks to describe the implementation of CETA for Afro-Colombian victims of violence in Buenaventura and Quibdó, Colombia through case studieswith individual in-depth interviews with Lay Psychosocial Community Workers (LPCW, supervisors, and coordinators responsible for implementing CETA. From this six core categories were obtained: 1. Effect of armed conflict and poverty 2. Trauma severity 3. Perceived changes with CETA 4. Characteristics and LPCW’s performance 5. Afro-Colombian culturalapproach and 6. Strategies to promote users’ well-being.Colombian Pacific’s scenario implies several factors, such as the active armed conflict, economic crisis, and lack of mental health care resources, affecting the implementation process and the intervention effects. This implies the need to establish and strengthen partnerships between institutions in order to administer necessary mental health care for victims of violence in the Colombian Pacific.

The article investigates the performance of an integrated system for the energy recovery from biomass and waste based on anaerobic digestion, gasification and water treatment. In the proposed system, the organic fraction of waste of the digestible biomass is fed into an anaerobic digester, while a part of the combustible fraction of the municipal solid waste is gasified. Thus, the obtained biogas and syngas are used as a fuel for running a cogeneration system based on an internal combustion engine to produce electric and thermal power. The waste water produced by the integrated plant is recovered by means of both forward and inverse osmosis. The different processes, as well as the main components of the system, are modelled by means of a lumped and distributed parameter approach and the main outputs of the integrated plant such as the electric and thermal power and the amount of purified water are calculated. Finally, the implementation of the proposed system is evaluated for urban areas with a different number of inhabitants and the relating performance is estimated in terms of the main outputs of the system.
