    Endoscopic ultrasound is the most accurate imaging modality for the diagnosis of pancreatic cancer, and endoscopic ultrasound-guided fine needle injection has already been used for palliative interventions. Surgical resection is currently the standard treatment for pancreatic insulinoma. Medical treatment may be necessary for symptomatic patients with unresectable disease. Case reports have been published about the success of endoscopic ultrasound-guided alcoholic ablation, but it has not been reported previously in Hungarian literature. The authors present the history of an 83-year-old woman who was evaluated because of repeated hypoglycemic coma occurring during the night. Endosonographic image and laboratory findings (elevated serum insulin and chromogranin A) revealed pancreatic insulinoma. Because of severe comorbidities and high risk of surgical resection, the decision was made to ablate the insulinoma by endoscopic ultrasound-guided alcohol injection. A total of 3 mL 95% ethanol was injected into the tumor. Despite the discontinuation of the diazoxide therapy the hypoglycemic episodes disappeared. This case history confirms that endoscopic ultrasound-guided alcoholic ablation is a novel, minimal invasive alternative treatment for patients with pancreatic neuroendocrine tumors in whom surgery is not feasible.

    In 1991, our group started to develop a catheter interventional therapy for hypertrophic obstructive cardiomyopathy (HOCM). The new concept was proposed in 1994. It is based on the conventional PTCA technique with the aim of inducing an artificial myocardial infarction by instillation of 96% ethanol into the most proximally situated septal branch of the left anterior descending coronary artery. This leads to a subaortic contraction disorder with subsequent decrease of the intraventricular pressure gradient, shrinkage of the hypertrophied septal bulge and widening of the outflow tract ("therapeutic remodeling"). The subaortic defect is small and well demarcated as assessed by left ventricular angiography, transesophageal echocardiography and 18 F-glucose positron emission tomography. The term transcoronary ablation of septum hypertrophy (TASH) was suggested. Our patient cohort that now comprises 215 therapeutic procedures in 187 patients underwent a large variety of prospective studies (maximum follow-up 4.5 years) including invasive controls at regular intervals, investigation of hemodynamics at rest and at exercise, transesophageal and transthoracic echocardiography, Doppler echocardiography during bicycle exercise, electrophysiologic testing, Holter monitoring and measurement of myocardial metabolism and perfusion, assessment of microembolic events by transcranial Doppler sonography and histological examinations. This article gives an overview and reports our increasing experience in applying TASH. The following post-TASH findings were obtained: significant hemodynamic and clinical improvement at rest and at exercise, decrease of septum thickness, increase of outflow tract area and decrease of induced ventricular tachycardia. There were well-demarcated, histologically atypical subaortic myocardial defects, no microembolic events, abnormal early peak of infarct related enzymes, and no change of baroreflex sensitivity.

    Barrett's esophagus (BE) is a premalignant condition that is associated with the development of esophageal adenocarcinoma. Risk factors that have been associated with the development of BE include male gender, Caucasian race, chronic gastroesophageal reflux disease, smoking, age >50 and obesity. The current management of BE is dependent on underlying pathological changes and treatment can range from surveillance endoscopy with daily proton pump inhibitor (PPI) therapy in the setting of intestinal metaplasia or low-grade dysplasia (LGD) to radiofrequency ablation (RFA), endoscopic mucosal resection or surgical resection in the setting of high-grade dysplasia. We report the case of a morbidly obese patient who was found to have long-segment BE with LGD during preoperative work-up for weight loss surgery with Roux-en-Y gastric bypass (RYGBP). The patient underwent successful RFA for the treatment of her BE before and after her RYGBP procedure. At 5-year follow-up, there was minimal progression of BE after treatment. PMID:26945777

    2016-05-01

    Narcolepsy type 1 and narcolepsy type 2 are central disorders of hypersomnolence. Narcolepsy type 1 is characterized by excessive daytime sleepiness and cataplexy and is associated with hypocretin-1 deficiency. On the other hand, in narcolepsy type 2, cerebrospinal fluid hypocretin-1 levels are normal and cataplexy absent. Despite major advances in our understanding of narcolepsy mechanisms, its current management is only symptomatic. Treatment options may vary from a single drug that targets several symptoms, or multiple medications that each treats a specific symptom. In recent years, narcolepsy treatment has changed with the widespread use of modafinil/armodafinil for daytime sleepiness, antidepressants (selective serotonin and dual serotonin and noradrenalin reuptake inhibitors) for cataplexy, and sodium oxybate for both symptoms. Other psychostimulants can also be used, such as methylphenidate, pitolisant and rarely amphetamines, as third-line therapy. Importantly, clinically relevant subjective and objective measures of daytime sleepiness are required to monitor the treatment efficacy and to provide guidance on whether the treatment goals are met. Associated symptoms and comorbid conditions, such as hypnagogic/hypnopompic hallucinations, sleep paralysis, disturbed nighttime sleep, unpleasant dreams, REM- and non REM-related parasomnias, depressive symptoms, overweight/obesity, and obstructive sleep apnea, should also be taken into account and managed, if required. In the near future, the efficacy of new wake-promoting drugs, anticataplectic agents, hypocretin replacement therapy and immunotherapy at the early stages of the disease should also be evaluated.

    Varicose veins are a common condition that can be treated surgically. Available operative modalities include saphenous venous ligation and stripping, phlebectomy, endovenous laser therapy and radiofrequency ablation. Radiofrequency ablation is the newest of these technologies, and to our knowledge our group was the first to use it in Canada. Our experience suggests that it is a safe and effective treatment for varicose veins, with high levels of patient satisfaction reported at short-term follow-up. More studies are needed to assess long-term effectiveness and compare the various available treatment options for varicose veins.

    2016-10-01

    The aim of this study was to evaluate the effectiveness of CyberKnife-based stereotactic ablative radiotherapy on prostate cancer lymph node metastases. Our material consisted of 18 patients with 31 metastatic lymph nodes irradiated between 2011 and 2014 using CyberKnife-based stereotactic ablative radiotherapy. Patients were irradiated using fraction dose varied from 6 to 15 Gy (median 10), to the total dose of 24 to 45 Gy (median 30). Irradiated lymph node size varied from 0.4 to 4.0 cm. In all, 9 patients had single lymph node metastasis and 9 patients had metastases of 2 to 4 lymph nodes. Prostate-specific antigen concentration before radiotherapy varied from 0.01 to 15.58 (mean 6.97; median 4.66). All patients at the time of radiotherapy and follow-up received androgen deprivation therapy. Mann-Whitney U, Kaplan-Meier method, and log-rank tests were used in statistical analysis. We obtained the following results: after CyberKnife stereotactic ablative radiotherapy, prostate-specific antigen concentration dropped in majority of cases and during the last control varied from 0.00 to 258.00 (median 2.5), and was lower in patients without dissemination to other organs (P = .01). Complete regression was found in 12 lesions, stable disease in 13, and progression in 4. In 7 patients, the dissemination to other organs occurred. Our results allow us to conclude that CyberKnife stereotactic ablative radiotherapy of prostate cancer lymph node oligometastases gives good local control and relatively good prostate-specific antigen response.

  1. Thermal ablation for the treatment of abdominal tumors.

    Science.gov (United States)

    Brace, Christopher L; Hinshaw, J Louis; Lubner, Meghan G

    2011-03-07

    Percutaneous thermal ablation is an emerging treatment option for many tumors of the abdomen not amenable to conventional treatments. During a thermal ablation procedure, a thin applicator is guided into the target tumor under imaging guidance. Energy is then applied to the tissue until temperatures rise to cytotoxic levels (50-60 °C). Various energy sources are available to heat biological tissues, including radiofrequency (RF) electrical current, microwaves, laser light and ultrasonic waves. Of these, RF and microwave ablation are most commonly used worldwide. During RF ablation, alternating electrical current (~500 kHz) produces resistive heating around the interstitial electrode. Skin surface electrodes (ground pads) are used to complete the electrical circuit. RF ablation has been in use for nearly 20 years, with good results for local tumor control, extended survival and low complication rates. Recent studies suggest RF ablation may be a first-line treatment option for small hepatocellular carcinoma and renal-cell carcinoma. However, RF heating is hampered by local blood flow and high electrical impedance tissues (eg, lung, bone, desiccated or charred tissue). Microwaves may alleviate some of these problems by producing faster, volumetric heating. To create larger or conformal ablations, multiple microwave antennas can be used simultaneously while RF electrodes require sequential operation, which limits their efficiency. Early experiences with microwave systems suggest efficacy and safety similar to, or better than RF devices. Alternatively, cryoablation freezes the target tissues to lethal levels (-20 to -40 °C). Percutaneous cryoablation has been shown to be effective against RCC and many metastatic tumors, particularly colorectal cancer, in the liver. Cryoablation may also be associated with less post-procedure pain and faster recovery for some indications. Cryoablation is often contraindicated for primary liver cancer due to underlying coagulopathy and

RFTA ablation is also an option for the palliation of localized, painful osteolytic metastatic and myeloma lesions. The reduction in pain improves the quality of life of patients with cancer, who often have multiple morbidities and a limited life expectancy. In some cases, these patients are treated with RFTA because conventional therapies (surgery, radiotherapy, chemotherapy, etc.) have been exhausted. In other cases, it is combined with conventional therapies or other percutaneous treatments, e.g., cementoplasty, offering faster pain relief and bone strengthening. A multidisciplinary approach to the management of these patients is recommended to select the optimal treatment, including orthopaedic surgeons, neurosurgeons, medical and radiation oncologists and interventional radiologists.

    Qureshi, N S

    2009-12-01

    Threatened miscarriage, as demonstrated by vaginal bleeding with or without abdominal cramps, is a common complication of pregnancy. It occurs in about 20% of recognised pregnancies. Risk of miscarriage is increased in older women and those with a history of miscarriage. Low serum levels of progesterone or human chorionic gonadotrophin (hCG) are a risk factor for miscarriage. Other risk factors include heavy bleeding, early gestational age and an empty gestational sac of >15-17 mm diameter. Clinical history and examination, maternal serum biochemistry and ultrasound findings provide valuable information about the prognosis and are important to establish in order to determine potential treatment options. Although bed rest is the most common choice of treatment, there is little evidence of its value. Other options include luteal support with progesterone, dydrogesterone or hCG. There is some evidence from clinical studies indicating that progesterone or dydrogesterone may reduce the rate of miscarriage, although further data from double-blind, randomised-controlled trials are necessary to confirm efficacy.

    2016-05-01

    Scarring is the consequence of surgery, trauma or different skin diseases. Apart from fresh, immature scars,that transform into mature scars over the course of would healing and that do not require further treatment,linear hypertrophic scars, widespread hypertrophic scars, keloids and atrophic scars exist. Symptoms like pruritusand pain, stigmatization as well as functional and aesthetic impairments that are very disturbing for the affected patients can bethe basis for the desire for treatment. Today, a multitude of options for the treatment and prevention of scars exists. Topical agents based on silicone or onion extract, intralesional injections of cristalline glucocorticoids (oftentimes in combinationwith cryotherapy) or 5-Fluorouracil as well as ablative and nonablative laser treatment are used. Current guidelines summarize the multitude of available treatment options and the currently available datafor the treating physicians, allowing them to make clear therapy recommendations for every single scar type. Relieving patients of their discomfort and doing their aesthetic demands justice is thus possible. Apart from scar prevention becoming more and more important, the increased use of modernlaser treatment options constitutes a key point in clinical scar treatment. At the same time the attention is turned to evaluating current therapeutic options with the help of contemporary study designs so as to graduallyimprove the level of evidence in scar treatment.

  2. New tumor ablation techniques for cancer treatment (microwave, electroporation)

    International Nuclear Information System (INIS)

    Since the introduction of radiofrequency ablation (RFA) for the treatment of liver tumors at the end of the 1990's, indications for local ablation techniques have been extended to other organs, in particular, the lungs, kidneys and bones. These techniques have also been improved, in particular to try and overcome the limitations of radiofrequency techniques, especially the significant decrease in complete ablation rates for tumors larger than 3 cm and tumors that are contiguous to vessels larger than 3 mm. Microwave ablation is a rapidly developing thermal ablation technique similar to RFA but with numerous differences. Electroporation, a non-thermal ablation technique with other possibilities, is in earlier stages of clinical development. (authors)

  3. Automated planning of ablation targets in atrial fibrillation treatment

    Keustermans, Johannes; De Buck, Stijn; Heidbüchel, Hein; Suetens, Paul

    2011-03-01

    Catheter based radio-frequency ablation is used as an invasive treatment of atrial fibrillation. This procedure is often guided by the use of 3D anatomical models obtained from CT, MRI or rotational angiography. During the intervention the operator accurately guides the catheter to prespecified target ablation lines. The planning stage, however, can be time consuming and operator dependent which is suboptimal both from a cost and health perspective. Therefore, we present a novel statistical model-based algorithm for locating ablation targets from 3D rotational angiography images. Based on a training data set of 20 patients, consisting of 3D rotational angiography images with 30 manually indicated ablation points, a statistical local appearance and shape model is built. The local appearance model is based on local image descriptors to capture the intensity patterns around each ablation point. The local shape model is constructed by embedding the ablation points in an undirected graph and imposing that each ablation point only interacts with its neighbors. Identifying the ablation points on a new 3D rotational angiography image is performed by proposing a set of possible candidate locations for each ablation point, as such, converting the problem into a labeling problem. The algorithm is validated using a leave-one-out-approach on the training data set, by computing the distance between the ablation lines obtained by the algorithm and the manually identified ablation points. The distance error is equal to 3.8+/-2.9 mm. As ablation lesion size is around 5-7 mm, automated planning of ablation targets by the presented approach is sufficiently accurate.

    Full Text Available Keratoconus is a progressive ectatic disorder of the cornea which often presents with fluctuating refraction and high irregular astigmatism. Correcting the vision of these patients is often a challenge because glasses are unable to correct the irregular astigmatism and regular contact lenses may not fit them very well. Topography-guided custom ablation treatment (T-CAT is a procedure of limited ablation of the cornea using excimer laser with the aim of regularizing the cornea, improving the quality of vision and possibly contact lens fit. The aim of the procedure is not to give a complete refractive correction. It has been tried with a lot of success by various groups of refractive surgeons around the world but a meticulous and methodical planning of the procedure is essential to ensure optimum results. In this paper, we attempt to elucidate the planning for a T-CAT procedure for various types of cones and asphericities.

Topography-guided custom ablation treatment (T-CAT) is a procedure of limited ablation of the cornea using excimer laser with the aim of regularizing the cornea, improving the quality of vision and possibly contact lens fit. The aim of the procedure is not to give a complete refractive correction. It has been tried with a lot of success by various groups of refractive surgeons around the world but a meticulous and methodical planning of the procedure is essential to ensure optimum results. In this paper, we attempt to elucidate the planning for a T-CAT procedure for various types of cones and asphericities. PMID:23925335

    2016-07-01

    Lung cancer had an estimated incidence of 221,200 in 2015, making up 13% of all cancer diagnoses. Tumor ablation is an important treatment option for nonsurgical lung cancer and pulmonary metastatic patients. Radiofrequency ablation has been used for over a decade with newer modalities, microwave ablation, cryoablation, and irreversible electroporation presenting as additional and possibly improved treatment options for patients. This minimally invasive therapy is best for small primary lesions or favorably located metastatic tumors. These technologies can offer palliation and sometimes cure of thoracic malignancies. This article discusses the current available technologies and techniques available for tumor ablation. PMID:27050331

    Psoriasis is a multifactorial inflammatory papulosquamous disease affecting 0.5% to 2% of the pediatric population. Pediatric psoriasis, presenting similar to adult psoriasis, significantly reduces patient quality of life, often requiring an individualized treatment approach for each patient. Combination and rotational therapy are helpful in reducing toxicity and maximizing efficacy. Patients with mild and limited disease severity respond well to topical treatment with steroids or vitamin D analogues, unlike moderate and severe psoriasis where sufficient remission is rarely achieved. Therefore phototherapy, systemic immunomodulators, or biologic agents are the next line of treatment to be considered. There is limited data available on the use and long-term safety of biologics in the pediatric population. Biologic agents must be administered by experienced dermatologists, only in patients with moderate-to-severe plaque psoriasis who are intolerant or refractory to other systemic conventional disease-modifying treatment or phototherapy, or if those treatments are contraindicated.

    From 2000 to 2010, 720 patients with facial trauma were admitted in Plastic Surgery Service of Argerich Hospital, Buenos Aires, Argentina; 58 of them with panfacial fractures were included in this study. Height velocity impact is the principal etiology, and most concomitant extrafacial injuries are neurocranium and cervical spine. Common affected areas were orbits, nose, and malar-zygoma. The timing of the treatment was airway evaluation, control of bleeding and consciousness, treatment of associated injuries, and finally facial reconstruction. The applications of craniofacial surgical techniques complete facial treatment in only operatory time by means of standard approaches like coronal, subciliar palpebral, upper and lower vestibular. The treatment was exploration to open sky; reduction and fijation with titanium plates; replacement of comminuted bones with bone autografts harvested iliac crest, calvary, and costal bones. The results were classificated acceptables in 48 (85%) and not acceptables in 9 (15%) according to successful reconstruction of the both form and armony facial, persistent esthetic and functional sequels, and postoperative complications. Postoperative complications were detected in 18 patients. According to most authors the use of internal rigid fixation and bone autograf permits obtaining the best aesthetic and functional results decreasing complications and sequels. The recuperation of tridimensional aspect of the face and aesthetic and functional pretrauma state must be the goal standard. PMID:27391510

    Desmoid tumours are benign, myofibroblastic stromal neoplasms common in Gardner's syndrome, which is a subtype of familial adenomatous polyposis characterized by colonic polyps, osteomas, thyroid cancer, epidermoid cysts, fibromas and sebaceous cysts. The primary treatment is surgery, followed by adjuvant radiotherapy, but the local recurrence rate is high, and wide resection can result in debilitating loss of function. We report the case of a 39-year-old man with Gardner's syndrome who had already undergone a total prophylactic colectomy. He developed desmoid tumours localized in the mesenteric root, abdominal wall and dorsal region, which were treated from 2003 through 2013 with several surgical procedures and percutaneous radiofrequency ablation. In 2008 and 2013, RFA was applied under ultrasonographic guidance to two desmoid tumours localized in the dorsal thoracic wall. The outcomes were low-grade pain and one case of superficial skin necrosis, but so far there has been no recurrence of desmoid tumours in these locations. Surgical resection remains the first-line therapy for patients with desmoid tumours, but wide resection may lead to a poor quality of life. Radiofrequency ablation is less invasive and expensive and is a possible therapeutic option for desmoid tumours in patients with Gardner's syndrome. PMID:25429890

    Full Text Available Aims: The aim was to identify Pseudotumor cerebri treatment options and assess their efficacy. Setting and Design: Review article. Materials and Methods: Existing literature and the authors′ experience were reviewed. Results: Treatment options range from observation to surgical intervention. Weight loss and medical treatment may be utilized in cases without vision loss or in combination with surgical treatment. Cerebrospinal fluid shunting procedures and/or optic nerve sheath decompression is indicated for severe vision loss or headache unresponsive to medical management. The recent use of endovascular stenting of transverse sinus stenoses has also demonstrated benefit in patients with pseudotumor cerebri. Conclusion: While each treatment form may be successful individually, a multimodal approach is typically utilized with treatments selected on a case-by-case basis.

    2016-09-01

    The concept of executive function is a so-called umbrella concept, so that it includes many different and in some cases mutually contradictory higher-level organizational abilities such as planning, monitoring, inhibition and control of action. Typically, the cause of an executive dysfunction is an underlying lesion in the prefrontal cortex or subcortical regions. Deficits in executive functions appear in the fields of cognition as well as behavior. Diagnosis requires the use of a wide-ranging repertoire of tests and questionnaires making it a time-consuming process. Different therapeutic approaches addressing the diverse symptoms of executive dysfunction, both positive and negative, are available. These include modification and manipulation of the environment and practice of cognitive repetitive procedures. The former are implemented particularly in cases of severely impaired persons. The latter are used in persons in whom cognitive dysfunctions are the dominating symptoms of the disorder.The operational area of therapeutic approaches using paper and pencil as well as computer programs limits them to treatment of cognitive dysfunction. If behavioral disturbances dominate the clinical picture, other procedures should be used.The effectiveness of cognitive therapy of executive dysfunction is well demonstrated according to the criteria of evidence-based medicine (EBM).

    Androgenetic alopecia (AGA) is characterized by a non-scarring progressive miniaturization of the hair follicle in predisposed men and women with a pattern distribution. Although AGA is a very prevalent condition, approved therapeutic options are limited. This article discusses the current treatment alternatives including their efficacy, safety profile, and quality of evidence. Finasteride and minoxidil for male androgenetic alopecia and minoxidil for female androgenetic alopecia still are the therapeutic options with the highest level evidence. The role of antiandrogens for female patients, the importance of adjuvant therapies, as well as new drugs and procedures are also addressed. PMID:27554257

  3. Nonsurgical Treatment Options for Basal Cell Carcinoma

    2011-01-01

    Full Text Available Basal cell carcinoma (BCC remains the most common form of nonmelanoma skin cancer (NMSC in Caucasians, with perhaps as many as 2 million new cases expected to occur in the United States in 2010. Many treatment options, including surgical interventions and nonsurgical alternatives, have been utilized to treat BCC. In this paper, two non-surgical options, imiquimod therapy and photodynamic therapy (PDT, will be discussed. Both modalities have demonstrated acceptable disease control rates, cosmetically superior outcomes, and short-term cost-effectiveness. Further studies evaluating long-term cure rates and long-term cost effectiveness of imiquimod therapy and PDT are needed.

    Hepatocellular cancer ranks fifth among cancers and is related to chronic viral hepatitis, alcohol abuse, steatohepatitis and liver autoimmunity. Surgical resection and orthotopic liver transplantation have curative potential, but fewer than 20% of patients are suitable candidates. Interventional treatments are offered to the vast majority of patients. Radiofrequency (RFA) and microwave ablation (MWA) are among the therapeutic modalities, with similar indications which include the presence of up to three lesions, smaller than 3 cm in size, and the absence of extrahepatic disease. The therapeutic effect of both methods relies on thermal injury, but MWA uses an electromagnetic field as opposed to electrical current used in RFA. Unlike MWA, the effect of RFA is partially limited by the heat-sink effect and increased impedance of the ablated tissue. Compared with RFA, MWA attains a more predictable ablation zone, permits simultaneous treatment of multiple lesions, and achieves larger coagulation volumes in a shorter procedural time. Major complications of both methods are comparable and infrequent (approximately 2%-3%), and they include haemorrhage, infection/abscess, visceral organ injury, liver failure, and pneumothorax. RFA may incur the additional complication of skin burns. Nevertheless, there is no compelling evidence for differences in clinical outcomes, including local recurrence rates and survival.

    Transrectal HIFU ablation has become a reasonable option for the treatment of localized prostate cancer in non-surgical patients, with 5-year disease-free survival similar to that of radiation therapy. It is also a promising salvage therapy of local recurrence after radiation therapy. These favourable results are partly due to recent improvements in prostate cancer imaging. However, further improvements are needed in patient selection, pre-operative localization of the tumor foci, assessment of the volume treated and early detection of recurrence. A better knowledge of the factors influencing the HIFU-induced tissue destruction and a better pre-operative assessment of them by imaging techniques should improve treatment outcome. Whereas prostate HIFU ablation is currently performed under transrectal ultrasound guidance, MR guidance with real-time operative monitoring of temperature will be available in the near future. If this technique will give better targeting and more uniform tissue destruction, its cost-effectiveness will have to be carefully evaluated. Finally, a recently reported synergistic effect between HIFU ablation and chemotherapy opens possibilities for treatment in high-risk or clinically advanced tumors.

    2010-06-20

    There has been a consistent trend towards delayed childbearing in most Western countries. Treatment options for age-related infertility includes controlled ovarian hyperstimulation with intrauterine insemination and in vitro fertilization (IVF). A sharp decline in pregnancy rate with advancing female age is noted with assisted reproductive technologies (ART) including IVF. Evaluation and treatment of infertility should not be delayed in women 35 years and older. No treatment other than oocyte donation has been shown to be effective for women over 40 and for those with compromised ovarian reserve, but its pratice is not easy in France hence the procreative tourism. As an increasing number of couples choose to postpone childbearing, they should be informed that maternal age is an important risk factor for failure to conceive. PMID:20623902

    2016-07-01

    Autosomal dominant chronic mucocutaneous candidiasis (AD-CMC) is a rare and severe primary immunodeficiency that is characterized by mucocutaneous fungal infection, autoimmunity, cerebral aneurysms, and oropharyngeal and esophageal cancer. Recently, it was discovered that STAT1 mutations are responsible for AD-CMC. These mutations lead to the inability of STAT1 to be dephosphorylated, resulting in hyperphosphorylation, increased binding to the DNA, and gain of function (GOF) effects on STAT1 signaling. Furthermore, a characteristic feature of AD-CMC patients is deficiency in the T-helper 17 (Th17) responses, which is believed to be the immunological cause of the mucocutaneous fungal infection. No targeted treatment other than lifelong antifungal prophylaxis exists for AD-CMC. However, the discovery of the genetic and immunological defects makes it now possible to explore new treatment strategies. This review will discuss immunomodulatory treatment options that can be explored in patients with STAT1 GOF mutations. PMID:27161991

    Current management of glaucoma entails the medical, laser, or surgical reduction of intraocular pressure (IOP) to a predetermined level of target IOP, which is commensurate with either stability or delayed progression of visual loss. In the published literature, the hypothesis is often made that IOP control implies a single IOP measurement over time. Although the follow-up of glaucoma patients with single IOP measurements is quick and convenient, such measurements often do not adequately reflect the untreated IOP characteristics, or indeed the quality of treated IOP control during the 24-h cycle. Since glaucoma is a 24-h disease and the damaging effect of elevated IOP is continuous, it is logical that we should aim to understand the efficacy of all treatment options throughout the 24-h period. This article first reviews the concept and value of diurnal and 24-h IOP monitoring. It then critically evaluates selected available evidence on the 24-h efficacy of medical, laser and surgical therapy options. During the past decade several controlled trials have significantly enhanced our understanding on the 24-h efficacy of all glaucoma therapy options. Nevertheless, more long-term evidence is needed to better evaluate the 24-h efficacy of glaucoma therapy and the precise impact of IOP characteristics on glaucomatous progression and visual prognosis.

    Ear disease, such as otitis externa, resulting in aggressive head shaking or ear scratching, is the most common cause of the development of aural hematomas in dogs and cats. An underlying immunologic cause has also been proposed to explain cartilage and blood vessel fragility. Numerous options exist for management of aural hematomas, from medical management alone with corticosteroids, to simple hematoma centesis, to surgical intervention. Because this condition is usually secondary to another disease process, regardless of mode of treatment, likelihood of recurrence is low if the underlying condition is managed properly.

    Many women will likely experience a sexual problem in their lifetime. Female sexual dysfunction is a broad term used to describe 3 categories of disorders of a multifactorial nature. Effective, but limited pharmacotherapeutic options exist to address female sexual dysfunction. The FDA recently approved the first agent for treatment of hypoactive sexual desire disorder in pre-menopausal women. Off-label use of hormonal therapies, particularly oestrogen and testosterone, are the most widely employed for female sexual dysfunction, particularly in post-menopausal women. Other drugs currently under investigation include phosphodiesterase inhibitors and agents that modulate dopamine or melanocortin receptors. PMID:27041639

    Minimally invasive treatment options have become increasingly feasible in restorative dentistry, due to the introduction of the adhesive technique in combination with restorative materials featuring translucent properties similar to those of natural teeth. Mechanical anchoring of restorations via conventional cementation represents a predominantly subtractive treatment approach that is gradually being superseded by a primarily defect-oriented additive method in prosthodontics. Modifications of conventional treatment procedures have led to the development of an economical approach to the removal of healthy tooth structure. This is possible because the planned treatment outcome is defined in a wax-up before the treatment is commenced and this wax-up is subsequently used as a reference during tooth preparation. Similarly, resin- bonded FDPs and implants have made it possible to preserve the natural tooth structure of potential abutment teeth. This report describes a number of clinical cases to demonstrate the principles of modern prosthetic treatment strategies and discusses these approaches in the context of minimally invasive prosthetic dentistry.

    The purpose of the present paper is to review and summarize the research supporting nonpharmacologic treatment options for insomnia. The different treatment approaches are described followed by a review of both original research articles and meta-analyses. Meta-analytic reviews suggest that common nonpharmacologic approaches exert, on average, medium to large effect sizes on SOL, WASO, NWAK, SQR, and SE while smaller effects are seen for TST. Stimulus control therapy, relaxation training, and CBT-I are considered standard treatments for insomnia by the American Academy of Sleep Medicine (AASM). Sleep restriction, multicomponent therapy without cognitive therapy, paradoxical intention, and biofeedback approaches have received some levels of support by the AASM. Sleep hygiene, imagery training, and cognitive therapy did not receive recommendation levels as single (standalone) therapies by the AASM due to lack of empirical evidence. Less common approaches have been introduced (Internet-based interventions, bright light treatment, biofeedback, mindfulness, acupuncture, and intensive sleep retraining) but require further research. Brief and group treatments have been shown to be as efficacious as longer and individually-administered treatments. Considerations are presented for special populations, including older adults, children and teens, individuals from diverse cultural backgrounds, insomnia comorbid with other disorders, and individuals who are taking hypnotics.

    2012-02-01

    PURPOSE: The incidence of osteoporosis-related fractures will increase substantially over the coming decades as the population ages globally. This has important economic and public health implications, contributing substantially to morbidity and excess mortality in this population. METHODS: When prescribing for older patients the effectiveness profile of drugs needs to be balanced against their tolerability in individual patients. RESULTS: Currently we have good anti-fracture data to support the use of many available anti-resorptive and anabolic drugs including bisphosphonates, strontium ranelate and recombinant human parathyroid hormone. We also have evidence to demonstrate the importance of calcium and vitamin D repletion in these patients. However, in recent years our understanding of normal bone physiology and the mechanisms underlying the development of osteoporosis has significantly advanced and this has led to the development of new therapies. Novel agents, particularly denosumab, but also inhibitors of cathepsin K and anabolic agents that act on Wnt signalling, will increase the therapeutic options for clinicians in the coming years. CONCLUSION: This review discusses the evidence supporting the use of currently available treatment options for osteoporosis and potential future advances in drug therapy. Particular consideration should be given when prescribing for certain older patients who have issues with compliance or tolerance and also in those with co-morbidities or levels of frailty that may restrict the choice of therapy. Understanding the evidence for the benefit and possible harm of osteoporosis treatments is critical to appropriate management of this patient population.

    Juvenile idiopathic arthritis (JIA) is the most common chronic rheumatic disease of the childhood with the highest risk of disability. Active disease persists in the adulthood in a significant portion of children with juvenile rheumatoid arthritis despite many developments in the diagnosis and treatment. Therefore, initiation of efficient treatment in the early period of the disease may provide faster control of the inflammation and prevention of long-term harms. In recent years, treatment options have also increased in children with juvenile idiopathic arthritis owing to biological medications. All biological medications used in children have been produced to target the etiopathogenesis leading to disease including anti-tumor necrosis factor, anti-interleukin 1 and anti-interleukin 6 drugs. In this review, scientific data about biological medications used in the treatment of rheumatoid arthritis and new treatment options will be discussed. PMID:26078691

Radiofrequency ablation (RFA) was approved as a new technique for the treatment of varicose veins in Japan in June 2014. In RFA, the ablation temperature is controlled by a sensor at the upper end of the catheter. The vein wall is heated with stable conductive power of 120 degrees C, resulting in endothelial denudation. The RFA method was approved in 1998 in Europe and in 1999 in the USA. The ClosurePLUS catheter was developed in 2003 and ClosureFAST in 2006. High occlusion rates and lower postoperative complication rates were reported with ClosureFAST than with ClosurePLUS. It is expected that this new ablation technique will control saphenous vein reflux with less pain and less ecchymosis after surgery. The treatment of varicose veins is less invasive with RFA devices and will become widely accepted as an alternative to conventional surgery for varicose veins in Japan.

The different treatment approaches are described followed by a review of both original research articles and meta-analyses. Meta-analytic reviews suggest that common nonpharmacologic approaches exert, on average, medium to large effect sizes on SOL, WASO, NWAK, SQR, and SE while smaller effects are seen for TST. Stimulus control therapy, relaxation training, and CBT-I are considered standard treatments for insomnia by the American Academy of Sleep Medicine (AASM. Sleep restriction, multicomponent therapy without cognitive therapy, paradoxical intention, and biofeedback approaches have received some levels of support by the AASM. Sleep hygiene, imagery training, and cognitive therapy did not receive recommendation levels as single (standalone therapies by the AASM due to lack of empirical evidence. Less common approaches have been introduced (Internet-based interventions, bright light treatment, biofeedback, mindfulness, acupuncture, and intensive sleep retraining but require further research. Brief and group treatments have been shown to be as efficacious as longer and individually-administered treatments. Considerations are presented for special populations, including older adults, children and teens, individuals from diverse cultural backgrounds, insomnia comorbid with other disorders, and individuals who are taking hypnotics.Keywords: insomnia, nonpharmacologic, psychological, behavioral, treatments, sleep

  1. High intensity focused ultrasound ablation: A new therapeutic option for solid tumors

    Full Text Available Surgery has been the standard of care in selected cases with solid tumors. However, a majority of patients are unable to undergo surgical resection because of the tumor sites, advanced stages, or poor general condition. High intensity focused ultrasound (HIFU is a novel non-invasive technique that is capable of producing coagulative necrosis at a precise focal point within the body, without harming overlying and adjacent structures even within the path of the beam. Diagnostic ultrasound was the first imaging modality used for guiding HIFU ablation in the 1990s. Over the last decade, thousands of patients with uterine fibroids, liver cancer, breast cancer, pancreatic cancer, bone tumors, renal cancer have been treated with ultrasound imaging-guided HIFU (USgHIFU worldwide. This USgHIFU system [Chongqing Haifu (HIFU Tech Co., Ltd., Chongqing, China] was first equipped in Asia, now in Europe. Several research groups have demonstrated that HIFU is safe and effective in treating human solid tumors. In 2004, the magnetic resonance guided focused ultrasound surgery (MRgFUS was approved by the United States Food and Drug Administration (FDA for clinical treatments of uterine fibroids. We conclude that HIFU offers patients another choice when no other treatment available or when patients refused surgical operation. This technique may play a key role in future clinical practice.

    Full Text Available Ahmed Badawy1 Abubaker Elnashar21Department of Obstetrics and Gynecology, Mansoura University, Mansoura, Egypt; 2Department of Obstetrics and Gynecology, Benha University, Benha, EgyptAbstract: Polycystic ovary syndrome (PCOS is the most common endocrine disorder in women. The clinical manifestation of PCOS varies from a mild menstrual disorder to severe disturbance of reproductive and metabolic functions. Management of women with PCOS depends on the symptoms. These could be ovulatory dysfunction-related infertility, menstrual disorders, or androgen-related symptoms. Weight loss improves the endocrine profile and increases the likelihood of ovulation and pregnancy. Normalization of menstrual cycles and ovulation could occur with modest weight loss as little as 5% of the initial weight. The treatment of obesity includes modifications in lifestyle (diet and exercise and medical and surgical treatment. In PCOS, anovulation relates to low follicle-stimulating hormone concentrations and the arrest of antral follicle growth in the final stages of maturation. This can be treated with medications such as clomiphene citrate, tamoxifen, aromatase inhibitors, metformin, glucocorticoids, or gonadotropins or surgically by laparoscopic ovarian drilling. In vitro fertilization will remain the last option to achieve pregnancy when others fail. Chronic anovulation over a long period of time is also associated with an increased risk of endometrial hyperplasia and carcinoma, which should be seriously investigated and treated. There are androgenic symptoms that will vary from patient to patient, such as hirsutism, acne, and/or alopecia. These are troublesome presentations to the patients and require adequate treatment. Alternative medicine has been emerging as one of the commonly practiced medicines for different health problems, including PCOS. This review underlines the contribution to the treatment of different symptoms.Keywords: treatment, polycystic ovary

    PurposeThe purpose of this study was to determine the feasibility, safety, and early effectiveness of percutaneous image-guided ablation as second-line treatment for symptomatic soft-tissue vascular anomalies (VA).Materials and MethodsAn IRB-approved retrospective review was undertaken of all patients who underwent percutaneous image-guided ablation as second-line therapy for treatment of symptomatic soft-tissue VA during the period from 1/1/2008 to 5/20/2014. US/CT- or MRI-guided and monitored cryoablation or MRI-guided and monitored laser ablation was performed. Clinical follow-up began at one-month post-ablation.ResultsEight patients with nine torso or lower extremity VA were treated with US/CT (N = 4) or MRI-guided (N = 2) cryoablation or MRI-guided laser ablation (N = 5) for moderate to severe pain (N = 7) or diffuse bleeding secondary to hemangioma–thrombocytopenia syndrome (N = 1). The median maximal diameter was 9.0 cm (6.5–11.1 cm) and 2.5 cm (2.3–5.3 cm) for VA undergoing cryoablation and laser ablation, respectively. Seven VA were ablated in one session, one VA initially treated with MRI-guided cryoablation for severe pain was re-treated with MRI-guided laser ablation due to persistent moderate pain, and one VA was treated in a planned two-stage session due to large VA size. At an average follow-up of 19.8 months (range 2–62 months), 7 of 7 patients with painful VA reported symptomatic pain relief. There was no recurrence of bleeding at five-year post-ablation in the patient with hemangioma–thrombocytopenia syndrome.

    The development of image-guided percutaneous techniques for local tumor ablation has been one of the major advances in the treatment of solid tumors. Among these methods, radiofrequency (RF) ablation is currently established as the primary ablative modality at most institutions. RF ablation is accepted as the best therapeutic choice for patients with early-stage hepatocellular carcinoma when liver transplantation or surgical resection are not suitable options and is considered as a viable alternate to surgery for inoperable patients with limited hepatic metastatic disease, especially from colorectal cancer. Recently, RF ablation has been demonstrated to be a safe and valuable treatment option for patients with unresectable or medically inoperable lung malignancies. Resection should remain the standard therapy for non-small cell lung cancer (NSCLC) but RF ablation may be better than conventional external-beam radiation for the treatment of the high-risk individual with NSCLC. Initial favourable outcomes encourage combining radiotherapy and RF ablation, especially for treating larger tumors. In the setting of colorectal cancer lung metastases, survival rates provided by RF ablation in selected patients, are substantially higher than those obtained with any chemotherapy regimens and provide indirect evidence that RF ablation therapy improves survival in patients with limited lung metastatic disease.

    We present a case of a patient with stage IIIC metastatic seminoma with a persistent chemorefractory liver lesion. The patient was deemed a poor surgical candidate due to the tumor’s aggressive biology with numerous other liver lesions treated with chemotherapy and a relatively high probability for additional recurrences. Further chemotherapy with curative intent was not a feasible option due to the fact that the patient had already received second-line high-dose chemotherapy and four cycles of third-line treatment complicated by renal failure, refractory thrombocytopenia, and debilitating neuropathy. After initial failure of laser, microwave ablation of the chemorefractory liver metastasis resulted in prolonged local tumor control and rendered the patient disease-free for more than 35 months, allowing him to regain an improved quality of life.

    We present our experience of the treatment of bone tumors with radiofrequency thermal ablation (RFTA). Over the past 4 years, we have treated 26 cases (22 benign and 4 malignant) using CT-guided RFTA. RFTA was the sole treatment in 19 cases and was combined with percutaneous cementation during the same session in the remaining seven cases. Our approach to the tumors was simplified, using a single point of entrance for both RFTA and percutaneous osteoplasty. In the benign cases, clinical success was defined as resolution of pain within 1 month of the procedure and no recurrence during the follow-up period. It was achieved in 19 out of the 21 patients in which curative treatment was attempted. The two non-resolved cases were a patient with osteoid osteoma who developed a symptomatic bone infarct after a symptom-free period of 2 months and another with femoral diaphysis osteoblastoma who suffered a pathological fracture after 8 months without symptoms. The procedure was considered clinically successful in the five cases (4 malign and 1 benign) in which palliative treatment was attempted, because there was a mean ({+-}SD) reduction in visual analogue scale (VAS) pain score from 9.0 {+-} 0.4 before the procedure to <4 during the follow-up period.

    @@ In the past decade, there is a great progress in the treatment of atrial fibrillation (AF) by transcatheter ablation. The catheter-based procedures have developed from Maze-like linear lesion, focal lesion to segmental electrical isolation of pulmonary veins and circumferential ablation under guidance of anatomical mapping, ablation energy developed from radiofrequency to multiple energy such as radiofrequency, ultrasound and cryoablation; and success rate has risen to 90% from around 30% in the past.1 Catheter ablation has been widely accepted as a treatment of AF and tends to substitute pharmacological therapy and become first-line treatment gradually. It must point out that, however, catheter ablation of AF is not perfect and there are many issues desiderating resolution.

  5. Current treatment options for management of anal intraepithelial neoplasia.

    Weis, Stephen E

    2013-01-01

    Anal squamous cell cancer is an uncommon malignancy caused by infection with oncogenic strains of Human papilloma virus. Anal cancer is much more common in immunocompromised persons, including those infected with Human immunodeficiency virus. High-grade anal intraepithelial neoplasia (HGAIN), the precursor of anal cancer, is identified by clinicians providing care for patients with anorectal disease, and is increasingly being identified during screening of immunosuppressed patients for anal dysplasia. The traditional treatment for HGAIN has been excision of macroscopic disease with margins. This approach is effective for patients with small unifocal HGAIN lesions. Patients with extensive multifocal HGAIN frequently have recurrence of HGAIN after excision, and may have postoperative complications of anal stenosis or fecal incontinence. This led to the suggestion by some that treatment for HGAIN should be delayed until patients developed anal cancer. Alternative approaches in identification and treatment have been developed to treat patients with multifocal or extensive HGAIN lesions. High-resolution anoscopy combines magnification with anoscopy and is being used to identify HGAIN and determine treatment margins. HGAIN can then be ablated with a number of modalities, including infrared coagulation, CO2 laser, and electrocautery. These methods for HGAIN ablation can be performed with local anesthesia on outpatients and are relatively well tolerated. High-resolution anoscopy-directed HGAIN ablation is evolving into a standard approach for initial treatment and then subsequent monitoring of a disease which should be expected to be recurrent. Another treatment approach for HGAIN is topical treatment, principally with 5-fluorouracil or imiquimod. Topical therapies have the advantage of being nonsurgical and are well suited for treating widespread multifocal disease. Topical treatments have the disadvantage of requiring extended treatment courses and causing a symptomatic

    Hepatocellular carcinoma (HCC) is the fifth most frequent cancer worldwide with high morbidity, mortality and increasing incidence. It is of note that the main curative therapies for HCC are hepatic resection and transplantation although the majority of patients at the time of presentation are not eligible for resection or orthotopic liver transplantation (OLT) due to the underlying cirrhosis. Currently, a variety of loco-regional therapies, including radiofrequency ablation (RFA), percutaneous ethanol injection (PEI), microwave coagulation therapy (MCT), transarterial chemoembolization (TACE) and others, have been developed as alternative treatment options for HCC. Among these techniques, RFA is currently the most widely used treatment, due to its several advantages, such as safety and efficacy. To date, the effectiveness of RFA for HCC is reduced by the presence of residual tumor as a consequence of insufficient treatment. In order to ameliorate the effects of RFA on HCC, several in vivo studies, have been performed on its application as single or in combination treatment with drugs or others loco-regional therapies, by using rabbit VX2 liver model. This represents an ideal model of liver cancers and is widely used for imaging and other experimental studies due to the rapid growth of these tumors and their similarity to human hepatocellular carcinoma. In order to elucidate the therapeutic potential of RFA with adjuvant treatments for HCC, we reviewed the latest findings on the RFA-based studies in rabbit VX2 hepatocarcinoma models. PMID:27525037

    Full Text Available Aim: To evaluate the local control of hepatic metastasis with radiofrequency ablation treatment. Materials and Methods: We did a retrospective analysis in 40 patients treated with radiofrequency ablation for hepatic metastasis. The tumors ablated included up to two metastatic liver lesions, with primaries in breast, gastrointestinal tract, cervix, etc. Radiofrequency ablation was performed under general anesthesia in all cases, using ultrasound guidance. Radionics Cool-Tip RF System was used to deliver the treatment. Results: The median age of patients treated was 49 years. There were 13 female and 27 male patients. The median tumor size ablated was 1.5 cm (0.75-4.0 cm. A total of 52 radiofrequency ablation cycles were delivered. Successful ablation was achieved in all patients with hepatic metastasis less than 3 cm in size. Pain was the most common complication seen (75%. One patients developed skin burns. At 2-year follow-up 7.5% of patients had locally recurrent disease. Conclusions: Radiofrequency ablation is a minimally invasive treatment modality. It can be useful in a select group of patients with solitary liver metastasis of less than 3 cm size.

    Crohn's disease is an autoimmune disorder that affects nearly 1.4 million Americans. The etiology of Crohn's disease is not completely understood, however, research has suggested a genetic link. There is currently no known cure for Crohn's disease and, as a result, most government-funded research is being conducted to increase the quality of life of afflicted patients (i.e. reducing chronic inflammation and alleviating growth impairment in pediatric patients). A number of treatment options are available including an alpha-4 integrin inhibitor and several TNF-alpha inhibitors. Furthermore, research is being conducted on several alternative treatment options to help understand exactly which cellular mechanisms (i.e. inducing apoptosis in leukocytes) are required for clinical efficacy. This review seeks to chronicle the current available treatment options for patients affected by Crohn's disease to aid in understanding potential cellular mechanistic requirements for an efficacious drug, and shed light on potential options for future treatment.

    Full Text Available Background: Acne scar is a complication of inflammatory acne due to the damage of skin. Various therapeutic modalities have been used for the treatment of acne scars. Among these treatments, minimal ablative fractional Er: YAG (Erbium: yttrium-aluminum-garnet laser is a popular treatment modality for the improvement of acne scars. In this study, we restrospectively analysed efficiency and tolerability of minimal ablative fractional Er: YAG laser therapy in the treatment of acne scars. Materials and Methods: Seventy one patients with acne scars treated with minimal ablative fractional Er: YAG laser in our clinic between November 2011 and April 2013 were retrospectively evaluated. Treatment parameters, demographic features and before and after pictures of the lesions were investigated from patients’ records in order to evaluate efficency of Er: YAG laser therapy. Patients’ photographs before and after treatment were compared. Clinical response was graded according to the percentage improvement. Side effects observed during treatment and in follow-up visits were evaluated from patients’ records. Results: Acne scar types included in the study were icepick (n=32, 45.1%, rolling (n=24, 33.9%, shallow boxed (n=7, 9.8% and deep boxed (n=8, 11.2%. Clinical improvement rates evaluated as 1.4% minimal, 38.1% moderate, 47.8% good and 2.7% excellent. Adverse effects were 16.8% erythema that lasted more 3 days, 4.2% postinflammatory hyperpigmentation and 7.0% acne aggravation. Clinical improvement (3.2, good-excellent and patient satisfaction rates (2.6, good-excellent for icepick type scars were very high. Similarly in shallow boxed scar types clinical improvement (2.8, good and patient satisfaction rates (2.6, good-excellent were high. However, in rolling scars and deep boxed scars clinical improvement rates were low. Conclusion: Minimal ablative fractional Er: YAG laser therapy is an effective and safe treatment option for acne scars, especially, in

    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

  1. Treatment options for paediatric pulmonary arterial hypertension

    Directory of Open Access Journals (Sweden)

    R.M.F. Berger

    2010-12-01

    Full Text Available Pulmonary arterial hypertension (PAH is a serious, progressive condition, which can present idiopathically or secondary to conditions such as systemic sclerosis or congenital heart disease. The condition exists in both adult and paediatric forms, which possess several similar characteristics. Adult and paediatric PAH can, however, be distinguished based on underlying pathology and the presence of age-specific conditions, some of which are related to poor lung development in children. Improved knowledge of vascular biology has led to the development of several PAH-specific therapies, which have demonstrated clinical benefits in adults, including improved exercise capacity and prolonged survival. Treatment data in paediatric PAH are scarce. Although limited, the existing data indicate that current treatments for paediatric PAH are well tolerated and effective, at least in the short- and medium-term. Nevertheless, the current guidelines for clinicians, which recommend use of the adult treatment algorithm in paediatric patients, appear justified when judged according to the available evidence. However, further randomised, controlled trials are necessary to increase the evidence base for treatment of paediatric PAH, especially in relation to age-specific conditions. At present, early initiation of treatment and combination pharmacological therapy may offer the most promising courses of action to improve outcomes in paediatric PAH.

  2. Hip Instability: Current Concepts and Treatment Options.

    2016-07-01

    Instability of the hip can manifest in a wide range of settings, with presenting symptoms including subtle discomfort at end range of motion or more dramatic dislocation of the joint. It can result from traumatic injury with dislocation or subluxation; atraumatic capsular laxity; structural bony abnormality, such as acetabular dysplasia; and iatrogenic injury. Initial treatment of the concentrically reduced joint often begins with physical therapy to strengthen dynamic stabilizers and to allow time for resolution of acute symptoms. Surgical treatment is aimed at repairing injured soft tissue structures, including static stabilizers, and addressing underlying bony structural deficiencies. PMID:27343395

    Full Text Available Robin C Wackernah,1 Matthew J Minnick,1 Peter Clapp2 1Department of Pharmacy Practice, 2Department of Pharmaceutical Sciences, School of Pharmacy, Rueckert-Hartman College for Health Professions, Regis University, Denver, CO, USA Abstract: Alcohol use disorders (AUD continue to be a concerning health issue worldwide. Harmful alcohol use leads to 2.5 million deaths annually worldwide. Multiple options exist for the management of dependence on alcohol, not all of which are approved by drug-regulating agencies. Current practice in treating AUD does not reflect the diversity of pharmacologic options that have potential to provide benefit, and guidance for clinicians is limited. Few medications are approved for treatment of AUD, and these have exhibited small and/or inconsistent effects in broad patient populations with diverse drinking patterns. The need for continued research into the treatment of this disease is evident in order to provide patients with more specific and effective options. This review describes the neurobiological mechanisms of AUD that are amenable to treatment and drug therapies that target pathophysiological conditions of AUD to reduce drinking. In addition, current literature on pharmacologic (both approved and non-approved treatment options for AUD offered in the United States and elsewhere are reviewed. The aim is to inform clinicians regarding the options for alcohol abuse treatment, keeping in mind that not all treatments are completely successful in reducing craving or heavy drinking or increasing abstinence.

  10. [Options for stress management in obesity treatment].

    Science.gov (United States)

    Czeglédi, Edit

    2016-02-14

    Overeating and physical inactivity are of great importance in the etiology of obesity. Psychological factors are often found in the background of life style. Chronic stress can contribute to physical inactivity and behaviors that hinder the keeping of a diet (e.g., irregular eating pattern, emotional eating). Results of randomized controlled trials show that relaxation can reduce emotional eating, improve cognitive restraint, and thereby reduce weight. However, stress management is more than relaxation. It consists of adaptive emotion-focused and problem-focused coping strategies and skills to improve relationships. Deflection skills may help in replacing emotional eating with other behaviors. Cognitive restructuring, saying no, and problem solving help to prevent or manage conflicts and difficulties otherwise would result in overeating due to distress. Developing stress management skills may result in greater compliance with the treatment. The techniques presented in the study can be easily applied by general practitioners or specialists, and provide tools for optimizing obesity treatment.

    Müller, Ulrich; Barr-Gillespie, Peter G

    2015-05-01

    Hearing loss is the most common form of sensory impairment in humans and affects more than 40 million people in the United States alone. No drug-based therapy has been approved by the Food and Drug Administration, and treatment mostly relies on devices such as hearing aids and cochlear implants. Over recent years, more than 100 genetic loci have been linked to hearing loss and many of the affected genes have been identified. This understanding of the genetic pathways that regulate auditory function has revealed new targets for pharmacological treatment of the disease. Moreover, approaches that are based on stem cells and gene therapy, which may have the potential to restore or maintain auditory function, are beginning to emerge. PMID:25792261

    The world is facing an ever-increasing problem with antibiotic resistant bacteria and we are rapidly heading for a post-antibiotic era. There is an urgent need to investigate alterative treatment options while there are still a few antibiotics left. Bacteriophages are viruses that specifically target bacteria. Before the development of antibiotics, some efforts were made to use bacteriophages as a treatment option, but most of this research stopped soon after the discovery of antibiotics. There are two different replication options which bacteriophages employ. These are the lytic and lysogenic life cycles. Both these life cycles have potential as treatment options. There are various advantages and disadvantages to the use of bacteriophages as treatment options. The main advantage is the specificity of bacteriophages and treatments can be designed to specifically target pathogenic bacteria while not negatively affecting the normal microbiota. There are various advantages to this. However, the high level of specificity also creates potential problems, the main being the requirement of highly specific diagnostic procedures. Another potential problem with phage therapy includes the development of immunity and limitations with the registration of phage therapy options. The latter is driving research toward the expression of phage genes which break the bacterial cell wall, which could then be used as a treatment option. Various aspects of phage therapy have been investigated in studies undertaken by our research group. We have investigated specificity of phages to various avian pathogenic E. coli isolates. Furthermore, the exciting NanoSAM technology has been employed to investigate bacteriophage replication and aspects of this will be discussed.

    Objective: To compare the costs of CT-guided radiofrequency ablation (RFA) and MR-guided laser ablation (LA) for minimally invasive percutaneous treatment of osteoid osteoma. Materials and methods: Between November 2005 and October 2011, 20 patients (14 males, 6 females, mean age 20.3 {+-} 9.1 years) underwent CT-guided RFA and 24 patients (18 males, 6 females; mean age, 23.8 {+-} 13.8 years) MR-guided LA (open 1.0 Tesla, Panorama HFO, Philips, Best, Netherlands) for osteoid osteoma diagnosed on the basis of clinical presentation and imaging findings. Prorated costs of equipment use (purchase, depreciation, and maintenance), staff costs, and expenditure for disposables were identified for CT-guided RFA and MR-guided LA procedures. Results: The average total costs per patient were EUR 1762 for CT-guided RFA and EUR 1417 for MR-guided LA. These were (RFA/LA) EUR 92/260 for equipment use, EUR 149/208 for staff, and EUR 870/300 for disposables. Conclusion: MR-guided LA is less expensive than CT-guided RFA for minimally invasive percutaneous ablation of osteoid osteoma. The higher costs of RFA are primarily due to the higher price of the disposable RFA probes.

    Full Text Available Stephen E Weis1,2 1Division of Dermatology, Department of Internal Medicine, University of North Texas Health Science Center at Fort Worth, 2Preventive Medicine Clinic, Tarrant County Public Health, Fort Worth, TX, USA Abstract: Anal squamous cell cancer is an uncommon malignancy caused by infection with oncogenic strains of Human papilloma virus. Anal cancer is much more common in immunocompromised persons, including those infected with Human immunodeficiency virus. High-grade anal intraepithelial neoplasia (HGAIN, the precursor of anal cancer, is identified by clinicians providing care for patients with anorectal disease, and is increasingly being identified during screening of immunosuppressed patients for anal dysplasia. The traditional treatment for HGAIN has been excision of macroscopic disease with margins. This approach is effective for patients with small unifocal HGAIN lesions. Patients with extensive multifocal HGAIN frequently have recurrence of HGAIN after excision, and may have postoperative complications of anal stenosis or fecal incontinence. This led to the suggestion by some that treatment for HGAIN should be delayed until patients developed anal cancer. Alternative approaches in identification and treatment have been developed to treat patients with multifocal or extensive HGAIN lesions. High-resolution anoscopy combines magnification with anoscopy and is being used to identify HGAIN and determine treatment margins. HGAIN can then be ablated with a number of modalities, including infrared coagulation, CO2 laser, and electrocautery. These methods for HGAIN ablation can be performed with local anesthesia on outpatients and are relatively well tolerated. High-resolution anoscopy-directed HGAIN ablation is evolving into a standard approach for initial treatment and then subsequent monitoring of a disease which should be expected to be recurrent. Another treatment approach for HGAIN is topical treatment, principally with 5

Although this hemodialysis complication has long been recognized, only recently it was associated with increased morbidity and mortality in dialysis patients. Endothelial cell dysfunction appears to be the major mechanism underlying this blood pressure phenomenon, and the role of extracellular volume and sodium overload remains to be better defined. To treat this potential cardiovascular health threat is necessary to identify and understand the factors that influence it. PMID:27148774

    Purpose: To study the effect of needle placement uncertainty on the expected probability of achieving complete focal target destruction in focal laser ablation (FLA) of prostate cancer. Methods: Using a simplified model of prostate cancer focal target, and focal laser ablation region shapes, Monte Carlo simulations of needle placement error were performed to estimate the probability of completely ablating a region of target tissue. Results: Graphs of the probability of complete focal target ablation are presented over clinically relevant ranges of focal target sizes and shapes, ablation region sizes, and levels of needle placement uncertainty. In addition, a table is provided for estimating the maximum target size that is treatable. The results predict that targets whose length is at least 5 mm smaller than the diameter of each ablation region can be confidently ablated using, at most, four laser fibers if the standard deviation in each component of needle placement error is less than 3 mm. However, targets larger than this (i.e., near to or exceeding the diameter of each ablation region) require more careful planning. This process is facilitated by using the table provided. Conclusions: The probability of completely ablating a focal target using FLA is sensitive to the level of needle placement uncertainty, especially as the target length approaches and becomes greater than the diameter of ablated tissue that each individual laser fiber can achieve. The results of this work can be used to help determine individual patient eligibility for prostate FLA, to guide the planning of prostate FLA, and to quantify the clinical benefit of using advanced systems for accurate needle delivery for this treatment modality.

  4. Pharmacologic Options for the Treatment of Sarcopenia.

    Morley, John E

    2016-04-01

    Sarcopenia is now clinically defined as a loss of muscle mass coupled with functional deterioration (either walking speed or distance or grip strength). Based on the FRAX studies suggesting that the questions without bone mineral density can be used to screen for osteoporosis, there is now a valid simple questionnaire to screen for sarcopenia, i.e., the SARC-F. Numerous factors have been implicated in the pathophysiology of sarcopenia. These include genetic factors, mitochondrial defects, decreased anabolic hormones (e.g., testosterone, vitamin D, growth hormone and insulin growth hormone-1), inflammatory cytokine excess, insulin resistance, decreased protein intake and activity, poor blood flow to muscle and deficiency of growth derived factor-11. Over the last decade, there has been a remarkable increase in our understanding of the molecular biology of muscle, resulting in a marked increase in potential future targets for the treatment of sarcopenia. At present, resistance exercise, protein supplementation, and vitamin D have been established as the basic treatment of sarcopenia. High-dose testosterone increases muscle power and function, but has a number of potentially limiting side effects. Other drugs in clinical development include selective androgen receptor molecules, ghrelin agonists, myostatin antibodies, activin IIR antagonists, angiotensin converting enzyme inhibitors, beta antagonists, and fast skeletal muscle troponin activators. As sarcopenia is a major predictor of frailty, hip fracture, disability, and mortality in older persons, the development of drugs to treat it is eagerly awaited. PMID:26100650

If left untreated, it can lead to increased risk of depression, poor memory, reduced concentration, poor work performance, and poor general health. Although gamma-aminobutyric acid (GABA ergic system remains the primary target for current insomnia treatments, still over-the-counter (OTC drugs with a different mechanism of action are in use for insomnia. OTC drugs target only one of the parallel arousing systems and may improve mild insomnia for a short period. They are not likely to improve symptoms over long-term and thus are not the ideal agents. Studies evaluating the efficacy and outcomes of sedative hypnotic drugs beyond 1 year are limited. Currently, there are no Food and Drug Administration approved pharmacotherapies for insomnia in the pediatric population. Increased understanding of complex neuronal networks involved in sleep and wake has led to the development of new drugs for insomnia that target a diverse range of receptors. Potential agents under investigations are targeting mechanisms and pathways including histamine (H1 receptor, melatonin, and orexin receptors.

    Full Text Available Dessy R Emril1 Kok-Yuen Ho21Neurology Department, Syiah Kuala University/Dr Zainoel Abidin Hospital, Banda Aceh, Indonesia; 2Pain Management Centre, Raffles Hospital, SingaporeAbstract: Trigeminal neuralgia (TN is a neuropathic pain condition affecting the face. It has a significant impact on the quality of life and physical function of patients. Evidence suggests that the likely etiology is vascular compression of the trigeminal nerve leading to focal demyelination and aberrant neural discharge. Secondary causes such as multiple sclerosis or brain tumors can also produce symptomatic TN. Treatment must be individualized to each patient. Carbamazepine remains the drug of choice in the first-line treatment of TN. Minimally invasive interventional pain therapies and surgery are possible options when drug therapy fails. Younger patients may benefit from microvascular decompression. Elderly patients with poor surgical risk may be more suitable for percutaneous trigeminal nerve rhizolysis. The technique of radiofrequency rhizolysis of the trigeminal nerve is described in detail in this review.Keywords: interventional treatment, minimally invasive, pain management, radiofrequency rhizolysis, trigeminal neuralgia 

  7. Psoriasis: characteristics, psychosocial effects and treatment options.

    Psoriasis is a complex chronic non-infectious inflammatory skin disease with a variety of different presentations. The classic presentation is of well-defined red plaques with silver scale. The characteristic scale makes the disorder highly visible and intrusive on the patient\\'s lifestyle. The visible nature of the disease ensures that psoriasis has both physical and psychosocial effects. In normal skin, epidermal cell reproduction and proliferation takes 28 days. In psoriasis this process is considerably accelerated to approximately 4 days, resulting in the deposit of immature cells on the skin. While the exact cause of this process is unknown, certain environmental and genetic factors are known to be triggers. Disease management depends on disease severity, psychosocial effects and the patient\\'s lifestyle. To effectively treat this disease the nurse must be skilled in psoriasis management, and in patient education and motivation. This article reviews the characteristics, aetiology, psychosocial effects and treatment strategies of psoriasis.

    Despite advances in implant design, the management of distal femur fractures remains challenging. Fracture comminution and intra-articular extension can make it difficult to obtain an adequate reduction while preserving the soft tissue attachments to bone fragments to allow for bone healing. Many implant manufacturers have developed optimal anatomically contoured, distal femoral locking plates with percutaneous guides. This environment allows for the application of lateral locked plates in a biologically friendly manner. Although initial reports had high success rates, more recently a high rate of nonunion has been found, particularly in elderly patients. Limited literature is available for the treatment of patients with osteoporotic bone and associated ipsilateral total knee replacement and hip replacement. We present a patient with a distal femur fracture with significant comminution in the setting of an ipsilateral total hip replacement. PMID:27441931

    Full Text Available Opioids are widely used drugs for treatment of pain and related disorders. Opiate addiction is a major public health concern in the United States causing significant increase in healthcare expenditure. They produce euphoria and sense of well-being which makes them addictive to some people. Used in higher doses they can lead to cardiac or respiratory compromise. They also impair cognition leading to impaired decision making. Opioids exert their effects by acting on three different types of receptors mu, delta, and kappa located on neuronal cell membranes causing inhibition of neurotransmitter release. Prolonged use of these drugs can lead to physical dependence causing withdrawal symptoms if a person stops using them. Commonly used medications to treat opiate addiction are methadone, LAAM (longer acting derivative of methadone, buprenorphine, and naltrexone. [Int J Res Med Sci 2016; 4(7.000: 2503-2507

    Naegleria fowleri has generated tremendous media attention over the last 5 years due to several high-profile cases. Several of these cases were followed very closely by the general public. N. fowleri is a eukaryotic, free-living amoeba belonging to the phylum Percolozoa. Naegleria amoebae are ubiquitous in the environment, being found in soil and bodies of freshwater, and feed on bacteria found in those locations. While N. fowleri infection appears to be quite rare compared to other diseases, the clinical manifestations of primary amoebic meningoencephalitis are devastating and nearly always fatal. Due to the rarity of N. fowleri infections in humans, there are no clinical trials to date that assess the efficacy of one treatment regimen over another. Most of the information regarding medication efficacy is based on either case reports or in vitro studies. This review will discuss the pathogenesis, diagnosis, pharmacotherapy, and prevention of N. fowleri infections in humans, including a brief review of all survivor cases in North America.

    We evaluated the efficacy and tolerability of antibiotic regimens and optimal duration of therapy in complicated and uncomplicated forms of spinal brucellosis. This is a multicentre, retrospective and comparative study involving a total of 293 patients with spinal brucellosis from 19 health institutions. Comparison of complicated and uncomplicated spinal brucellosis was statistically analysed. Complicated spinal brucellosis was diagnosed in 78 (26.6%) of our patients. Clinical presentation was found to be significantly more acute, with fever and weight loss, in patients in the complicated group. They had significantly higher leukocyte and platelet counts, erythrocyte sedimentation rates and C-reactive protein levels, and lower haemoglobulin levels. The involvement of the thoracic spine was significantly more frequent in complicated cases. Spondylodiscitis was complicated, with paravertebral abscess in 38 (13.0%), prevertebral abscess in 13 (4.4%), epidural abscess in 30 (10.2%), psoas abscess in 10 (3.4%) and radiculitis in 8 (2.7%) patients. The five major combination regimens were: doxycycline 200 mg/day, rifampicin 600 mg/day and streptomycin 1 g/day; doxycycline 200 mg/day, rifampicin 600 mg/day and gentamicin 5 mg/kg; doxycycline 200 mg/day and rifampicin 600 mg/day; doxycycline 200 mg/day and streptomycin 1 g/day; and doxycycline 200 mg/day, rifampicin 600 mg/day and ciprofloxacin 1 g/day. There were no significant therapeutic differences between these antibiotic groups; the results were similar regarding the complicated and uncomplicated groups. Patients were mostly treated with doxycycline and rifampicin with or without an aminoglycoside. In the former subgroup, complicated cases received antibiotics for a longer duration than uncomplicated cases. Early recognition of complicated cases is critical in preventing devastating complications. Antimicrobial treatment should be prolonged in complicated spinal brucellosis in particular.

Radiotherapy is the primary treatment modality. The role of systemic therapy has become more prominent. Based on multiple phase III studies and meta-analyses, concurrent cisplatin-based chemoradiotherapy is the current standard of care for locally advanced disease (American Joint Committee on Cancer manual [7th edition] stages II–IVb. The reported failure-free survival rates from phase II trials are encouraging for induction + concurrent chemoradiotherapy. Data from ongoing phase III trials comparing induction + concurrent chemoradiotherapy with concurrent chemoradiotherapy will validate the results of these phase II studies. Intensity-modulated radiotherapy techniques are recommended if the resources are available. Locoregional control exceeding 90% and reduced xerostomia-related toxicities can now be achieved using intensity-modulated radiotherapy, although distant control remains the most pressing research problem. The promising results of targeted therapy and Epstein–Barr virus-specific immunotherapy from early clinical trials should be validated in phase III clinical trials. New technology, more effective and less toxic chemotherapy regimens, and targeted therapy offer new opportunities for treating nasopharyngeal carcinoma.Keywords: nasopharyngeal carcinoma, intensity-modulated radiotherapy, chemoradiotherapy, molecular targeted agents, immunotherapy, prognostic markers

    Full Text Available Hillel Sternlicht,1 Ilya G Glezerman1,2 1Division of Nephrology and Hypertension, Weill Cornell Medical College, 2Renal Service, Memorial Sloan Kettering Cancer Center, New York, NY, USA Abstract: Hypercalcemia of malignancy affects up to one in five cancer patients during the course of their disease. It is associated with both liquid malignancies, commonly multiple myeloma, leukemia, and non-Hodgkins lymphoma and solid cancers, particularly breast and renal carcinomas as well as squamous cell carcinomas of any organ. The clinical manifestations of hypercalcemia are generally constitutional in nature and not specific to the inciting malignancy. Such physical manifestations can range from malaise to lethargy and confusion. Constipation and anorexia are common. Acute kidney injury is likely the most frequently encountered manifestation of end organ damage. Symptomatology is closely linked to both the absolute elevation of serum calcium levels and the rapidity of calcium rise. The majority of cases are humoral in etiology and related to parathyroid hormone-related protein (PTHrP. Approximately 20% of cases are the result of direct bone metastasis with extra-renal 1,25-dihydroxyvitamin D (calcitriol and ectopic parathyroid hormone production likely accounting for less than 1% of cases. The diagnosis of hypercalcemia of malignancy is confirmed either by an elevated PTHrP or by an evidence of bone metastasis in the appropriate clinical setting. Treatment is predicated on the patient’s symptoms and absolute serum calcium level. Interventions are aimed at lowering the serum calcium concentration by inhibiting bone resorption and increasing urinary calcium excretion, the former accomplished via bisphosphonate therapy and the latter with aggressive hydration. Novel therapies for refractory disease include denosumab, a monoclonal antibody against the receptor activator of nuclear factor κB ligand, and the calcimimetic cinacalcet. Finally, anti

    Full Text Available Hormon therapy of the female Kallmann’s Syndrome patient in the setting of a pulmonary embolism presents a challenge. A female with hypogonadotropic hypogonadism is usually presented with two treatment options - combined gonadal hormone replacement or pulsatile gonadotropin releasing hormone. When a patient incurs a contraindication to hormonal therapy, the management of their endocrine disorder becomes much more challenging. Providers and patients must consider the advantages and disadvantages to each treatment option, including the possibility of not treating at all. Given the lack of literature on this rare combination of events, herein we review Kallmann’s Syndrome and its therapeutic options, as well as the hypercoagulability associated with hormone therapy to guide our decision-making process in a true case scenario.

    The purpose of this study was to investigate the safety and efficacy of endovenous laser ablation as a treatment for recurrent symptomatic saphenous insufficiency occurring after saphenous vein ligation and stripping. A single-center retrospective review of patients who received endovenous laser ablation as a treatment for recurrent symptomatic saphenous insufficiency after ligation and stripping between November 2003 and October 2006 was performed. Fifty-six insufficient saphenous systems were identified in 38 patients. Follow-up consisted of a clinical examination in all patients as well as selective lower-extremity duplex ultrasound as clinically indicated. All 38 patients demonstrated complete closure of the insufficient saphenous vein by clinical examination and/or duplex ultrasound evaluation. Preoperative symptoms resolved after treatment in all 38 patients. No major complications were identified. Endovenous laser ablation of recurrent symptomatic saphenous venous insufficiency is a safe and effective treatment in patients who develop recurrent symptoms after saphenous vein ligation and stripping.

  16. Stepladder Reconstructive Options in Post-Ablative Complex Surgical Defects in the Head and Neck

    International Nuclear Information System (INIS)

    Background: Reconstruction of head and neck defects can pose many challenges to the reconstructive head and neck surgeon. Achieving the best cosmetic and functional results without compromising the safety of oncologic surgery are the primary reconstructive goals. Speech and articulation are particularly important in oral reconstructive procedures. In addition, preservation of the integrity and function of the donor sites should always be considered in all reconstructive procedures. Aim of the Study: The aim of the study is to evaluate different reconstructive options in complex defects of the head and neck region after resection of malignant tumours. The feasibility of the reconstructive ladder starting from simple techniques such as local flaps and skin grafts up to free flaps will be assessed. Patients and Methods: In this study we evaluated different reconstructive procedures used in 50 patients with complex head and neck defects undertaken at the department of surgery at the National Cancer Institute between July 2003 and December 2007. Results: The average age of patients was 52 years and the range was 26-67 years. Most of the tumours were either squamous cell carcinoma (74%) or Basal cell carcinoma (20%). Tumour sites included the nose (6%), lip (10%), cheek (12%) scalp (6%) as well as mucosal defects of the oral cavity (40%) and the hypopharynx (20%). We used local flaps and skin grafts in reconstruction in 36% of cases and pedicled flaps in 32% while free flaps were used in 32% of cases. Complications occurred in 32% of patients of which total flaps loss constituted 6% and partial flap loss 4%. Minor complications such as oro-cutaneous fistulae, wound infection, seroma and haematoma were noticed in 22% and all of them were treated conservatively. The final functional and aesthetic results were satisfactory in 60% of cases while poor results were encountered in patients who suffered some degree of flap loss.

  1. Effluent treatment options for nuclear thermal propulsion system ground tests

    International Nuclear Information System (INIS)

    A variety of approaches for handling effluent from nuclear thermal propulsion system ground tests in an environmentally acceptable manner are discussed. The functional requirements of effluent treatment are defined and concept options are presented within the framework of these requirements. System concepts differ primarily in the choice of fission-product retention and waste handling concepts. The concept options considered range from closed cycle (venting the exhaust to a closed volume or recirculating the hydrogen in a closed loop) to open cycle (real time processing and venting of the effluent).

Individual patient characteristics must be considered when making treatment choices, especially from an adverse event (AE or tolerability perspective. Despite the availability of numerous AAs, after appraising patient characteristics at the time of treatment selection, physicians may quickly run out of tolerable treatment options. Patients and methods: AE risk factors, defined as having either a prior history of an AE or a risk factor for that AE, were determined for Medicaid-insured and Commercially insured patients using database analysis. Patients receiving AA treatment between January 1, 2010 and December 31, 2012 defined the index date of first observed AA prescription during this period. Nine AAs were evaluated for association with AE risk factors as informed by drug prescribing information from the different manufacturers and published meta-analyses. The proportion of patients with pre-index AE risk factors prescribed an AA associated with that risk factor was then determined. Results: A high proportion of patients (>80% were prescribed an AA associated with extrapyramidal symptoms or akathisia despite experiencing extrapyramidal symptoms or akathisia prior to AA treatment initiation. Similar trends were observed among patients with diabetes (>60% and obesity (>40%. From the nine treatment

    Full Text Available Multiple Sclerosis (MS is a slowly progressive, immunologically mediated disease of the CNS. The recent years have witnessed great efforts in establishing new therapeutic options for multiple sclerosis. There is a clear need for more effective, safe and at the same time orally available treatment options. Here we review the recently approved drug Dimethyl fumarate (DMF, Tecfidera® as a new therapeutic option for MS and its role in context to the existing oral treatment options for MS. Dimethyl fumarate is the methyl ester of fumaric acid and has been claimed to possess immunomodulatory properties and is already in clinical use as Fumaderm for severe systemic psoriasis. In addition, Dimethyl fumarate was also shown to act on the blood-brain barrier and exert neuroprotective properties via activation of anti-oxidative pathways and displayed beneficial effects in experimental autoimmune encephalomyelitis (EAE, a model mimicking many aspects of MS. Based on two global phase III studies. Dimethyl fumarate has been clinically proven to significantly reduce important measures of disease activity, including relapses and development of brain lesions, as well as to slow disability progression over time, while demonstrating a favourable safety and tolerability profile.

    Hidradenitis suppurativa (HS) is a chronic inflammatory disease that commonly develops painful, deep dermal abscesses and chronic, draining sinus tracts. Classically, pharmacologic and surgical therapies have been effective for reducing lesion activity and inflammation, but provide only modest success in the prevention of future recurrences and disease progression. Adjunctive therapies, such as laser and light-based therapies, have become more commonly used in the management of HS. These therapies work to reduce the occurrence of painful HS flare-ups by decreasing the number of hair follicles, sebaceous glands, and bacteria in affected areas, and by ablatively debulking chronic lesions. The best results are seen when treatment is individualized, taking disease severity into consideration when selecting specific energy-based approaches. This article will discuss various light-based therapies and the evidence supporting their use in the management of HS. PMID:26470622

    2008-07-01

    Steam assisted gravity drainage (SAGD) water treatment facilities produce concentrated waste streams that contain high concentrations of total dissolved solids. The waste streams are typically partially recycled to upstream processes or injected into wells. However, these methods can result in the precipitation of silicate compounds and chemical imbalances in upstream water treatment processes. This study simulated 2 SAGD processes and MVC and once-through steam generator (OTSG) waste water treatment options. MVC waste water treatments were simulated with sulfuric acid only; with sulfuric acid and magnesium oxide; and low TH-high silica OTSG blowdown. Results of the simulations showed that the waste water generated was adequately treated with a combination of acid and magox. Further reductions in pH reduced silica contents and alkalinity. Costs for the treatment were estimated at $6.17 per metre{sup 3} for MVC waste water and $1.77 m{sup 3} for blowdown waste water. The addition of magox lowered the cost for silica removal to $4.60 per m{sup 3}. It was concluded that waste water treatment is needed to make produced water treatment options viable with the oil sands industry. 2 refs., 3 tabs., 10 figs.

    Full Text Available Patellofemoral instability not only involves lateral patellar dislocation, patellar mal-tracking or subluxation but can also cause a limiting disability for sports activities. Its underlying causes are known as morphological anomalies of the patellofemoral joint or the mechanical axis, femorotibial malrotation, variants of the knee extensor apparatus, and ligamentous insufficiencies often accompanied by poor proprioception. Athletes with such predisposing factors are either suffering from unspecific anterior knee pain or from slightly traumatic or recurrent lateral patellar dislocation Treatment options of patellar instability are vast, and need to be tailored individually depending on the athlete’s history, age, complaints and physical demands. Different conservative and surgical treatment options are reviewed and discussed, especially limited expectations after surgery.

    Carotid stump syndrome is one of the recognised causes of recurrent ipsilateral cerebrovascular events after occlusion of the internal carotid artery. It is believed that microemboli arising from the stump of the occluded internal carotid artery or the ipsilateral external carotid artery can pass into the middle cerebral artery circulation as a result of patent external carotid–internal carotid anastomotic channels. Different pathophysiologic causes of this syndrome and endovascular options for treatment are discussed.

    Abstract Otitis media (OM) has numerous presentations in children. Together with conventional medical therapies aimed to prevent and/or treat OM, a rising number of complementary and alternative medicine (CAM) treatment options can be offered. Since OM is common in children, parents may ask healthcare professionals about possible CAM therapies. Many physicians feel that their knowledge is limited regarding these therapies, and that they desire some information. Therefore, we conducted a literature review of CAM therapies for OM, taking into account that many of these treatments, their validity and efficacy and have not been scientifically demonstrated. We performed a search in MEDLINE (accessed via PubMed) using the following terms: “CAM” in conjunction with “OM” and “children. Retrieved publications regarding treatment of OM in children which included these terms included randomized controlled trials, prospective/retrospective studies, and case studies. The following CAM options for OM treatment in children were considered: acupuncture, homeopathy, herbal medicine/phytotherapy, osteopathy, chiropractic, xylitol, ear candling, vitamin D supplement, and systemic and topical probiotics. We reviewed each treatment and described the level of scientific evidence of the relevant publications. The therapeutic approaches commonly associated with CAM are usually conservative, and do not include drugs or surgery. Currently, CAM is not considered by physicians a potential treatment of OM, as there is limited supporting evidence. Further studies are warranted in order to evaluate the potential value of CAM therapies for OM. PMID:26871802

    Full Text Available Purpose: The aim of this study was to evaluate the efficacy of radiofrequency (RF ablation for benign thyroid nodules and assess the usefulness of internal factors (ultrasonographic findings and external factors (treatment-related findings in prediction of treatment efficacy. Methods: We evaluated 22 benign thyroid nodules from 19 patients treated with RF ablation between March 2010 and January 2013. The internal and external factors of these nodules were retrospectively reviewed and correlated with the therapeutic success and the volume reduction ratio (VRR. The volume and size of the nodules were determined before treatment, and the VRR was calculated at 6-month and 1-year follow-up examinations after RF ablation. Therapeutic success was defined as a >50% volume reduction. Results: The mean VRRs were 66.1±18.7% at 6 months and 74.3±16.7% at 1 year. The therapeutic success rate after 6 months and 1 year was 81.8% and 90.9%, respectively. At the 1-year follow-up, the margin of the nodule correlated with therapeutic success. Most of the successfully ablated nodules showed well-defined margins on initial ultrasonography (18/20, 90% (P=0.026. In addition, nodules with ill-defined margins showed a tendency toward having a low VRR at the 6-month and 1-year follow-up examinations. Conclusion: RF ablation was effective in decreasing the volume of benign thyroid nodules. Thyroid nodules with well-defined margins tended to show successful outcomes at the 1-year follow-up examination after RF ablation.

    Liver cancer is a malignancy of the digestive system and has a high morbidity and mortality rate. Local intervention has become a viable option in identifying liver treatment. The aim of the present study was to analyze the clinical effects of treating liver cancer in middle and advanced stages using ultrasound-guided percutaneous ethanol injection (PEI) in tumors combined with radiofrequency ablation (RFA). A total of 100 patients with stage III–IV liver cancers were selected to participate in the study. Patients were divided into groups. In group A, treatment was initiated with PEI and after 1–2 weeks RFA was applied while in group B treatment was initiated with RFA and after 1–2 weeks PEI was applied. Patients in group C received PEI and RFA simultaneously. The clinical effects in the 3 groups were compared after 6-month follow ups. The volume of tumor ablation necrosis in group A was significantly greater than that in the groups B and C, while the size was significantly smaller compared to groups B and C after ablation. For group A, the complete ablation rate was significantly higher than that in groups B and C, and the differences were statistically significant (P<0.05). Liver damage indices, including raising levels of glutamic-pyruvic transaminase and total bilirubin, were significantly decreased in group A (P<0.05). The survival rate in group A was also significantly higher than in groups B and C (P<0.05). In conclusion, for patients with liver cancer in middle and advanced stages, the treatment method using PEI followed by RFA was more beneficial in terms of improving the tumor ablation rate, alleviating liver damages and increasing survival rates.

    Full Text Available Capillary hemangiomas are the most common periocular and orbital tumors of childhood that typically arise in infancy. Though the diagnosis is frequently made on clinical examination, various diagnostic modalities may be helpful in initial evaluation and follow-up. Tests may be necessary in diagnosing suspect cases or aid in the differentiation of potential malignant tumors. In the vast majority of cases these tumors undergo spontaneous involution without sequelae. However, some periocular and orbital capillary hemangiomas require intervention to prevent serious complications. Other tumors require treatment to lessen the surgical burden for cosmetic repair. When treatment is necessary, there are a number of therapeutic options available. As there is no standard, potential risks and benefits must be discussed with the family and treatment should be specific in each case. A complete understanding of the natural history of the tumor, indications for treatment, and response to different therapies is imperative in managing this common lesion.

    Psoriasis is a complex, multifactorial disease that appears to be influenced by immune-mediated components. For many years the pathogenesis of psoriasis has been discordant; the clinical picture suggested that the psoriasis was secondary to abnormal keratinocyte proliferation and differentiation, but later the role of the T cell was revealed. A variety of treatment options range from topical agents (e.g., coal tar, dithranol, and emollients for milder forms) to systemic agents (i.e., methotrexate or cyclosporin), and phototherapy. Recently, biologics have been added to this list that target particular steps in the immune or inflammatory pathways. Various nanocarriers (e.g., liposomes, niosomes, and microemulsions) have been successfully exploited for the delivery of several antipsoriatic drugs. This review provides insight into various psoriasis treatment strategies-from conventional to novel-currently in use or in development as well as the novel targets that have been explored and/or investigated for anti-psoriatic therapy. The pathogenesis of psoriasis and some of the topical, systemic biological, and novel approaches currently in use or in development are reviewed here. The pros and cons of each treatment strategy are presented, as are some of the animal models used to study features reminiscent of psoriasis. This information can be used to better the understanding of treatment options for this disease. PMID:23510110

    Full Text Available Elena M Umland, Laura FalconieriJefferson School of Pharmacy, Thomas Jefferson University, Philadelphia, PA, USAAbstract: Vasomotor symptoms (VMS, including hot flashes and night sweats, occur in as many as 68.5% of women as a result of menopause. While the median duration of these symptoms is 4 years, approximately 10% of women continue to experience VMS as many as 12 years after their final menstrual period. As such, VMS have a significant impact on the quality of life and overall physical health of women experiencing VMS, leading to their pursuance of treatment to alleviate these symptoms. Management of VMS includes lifestyle modifications, some herbal and vitamin supplements, hormonal therapies including estrogen and tibolone, and nonhormonal therapies including clonidine, gabapentin, and some of the serotonin and serotonin–norepinephrine reuptake inhibitors. The latter agents, including desvenlafaxine, have been the focus of increased research as more is discovered about the roles of serotonin and norepinephrine in the thermoregulatory control system. This review will include an overview of VMS as they relate to menopause. It will discuss the risk factors for VMS as well as the proposed pathophysiology behind their occurrence. The variety of treatment options for VMS will be discussed. Focus will be given to the role of desvenlafaxine as a treatment option for VMS management.Keywords: menopause, vasomotor symptoms, hot flashes, vasomotor symptom treatment, desvenlafaxine

  1. Percutaneous thermal ablation of renal neoplasms

    International Nuclear Information System (INIS)

    Due to modern examination techniques such as multidetector computed tomography and high-field magnetic resonance imaging, the detection rate of renal neoplasms is continually increasing. Even though tumors exceeding 4 cm in diameter rarely metastasize, all renal lesions that are possible neoplasms should be treated. Traditional treatment techniques include radical nephrectomy or nephron-sparing resection, which are increasingly performed laparoscopically. Modern thermal ablation techniques such as hyperthermal techniques like radiofrequency ablation RFA, laser induced thermal ablation LITT, focused ultrasound FUS and microwave therapy MW, as well as hypothermal techniques (cryotherapy) may be a useful treatment option for patients who are unfit for or refuse surgical resection. Cryotherapy is the oldest and best known thermal ablation technique and can be performed laparoscopically or percutaneously. Since subzero temperatures have no antistyptic effect, additional maneuvers must be performed to control bleeding. Percutaneous cryotherapy of renal tumors is a new and interesting method, but experience with it is still limited. Radiofrequency ablation is the most frequently used method. Modern probe design allows volumes between 2 and 5 cm in diameter to be ablated. Due to hyperthermal tract ablation, the procedure is deemed to be safe and has a low complication rate. Although there are no randomized comparative studies to open resection, the preliminary results for renal RFA are promising and show RFA to be superior to other thermal ablation techniques. Clinical success rates are over 90% for both, cryo- and radiofrequency ablation. Whereas laser induced thermal therapy is established in hepatic ablation, experience is minimal with respect to renal application. For lesions of more than 2 cm in diameter, additional cooling catheters are required. MR thermometry offers temperature control during ablation. Microwave ablation is characterized by small ablation volumes

    Healthcare waste management and treatment is one of the national priority tasks of China's Tenth Five-Year Plan.Numerous installations disposing medical waste have already operated the project or under construction to the operation in 2006. This paper focuses on the assessment of existing and fu~re options to handle medical waste (MW). Internationally available and so far in China applied technologies and management practice are analysed, including the problems how to materials. Non-hazardous MW can be managed and treated in analogue to municipal solid waste (MSW). In most of the European countries decentralised hospital incinerators have been, because of high operation costs and pollution problems,widely banned and replaced by pre-treatment technologies at the source and centralised incineration plants for hazardous MW.Information for adapting and further developing MW management solutions and treatment technologies in China and applying the most appropriate MWM practice is provided.

    Depression is found in about 30%-40% of all patients with Parkinson's disease (PD), but only a small percentage (about 20%) receive treatment. As a consequence, many PD patients suffer with reduced health-related quality of life. To address quality of life in depressed PD patients, we reviewed the literature on the health correlates of depression in PD (eg, cognitive function), etiology of depression in PD, and treatment options (ie, antidepressants, electroconvulsive therapy, and psychotherapy). The current review is unique in its focus on psychosocial aspects, as well as neuropathological factors, of depression in PD. Overall, we conclude that neurochemical (eg, serotonin) and psychosocial factors (eg, coping style, self-esteem, and social support) contribute to the affective disturbances found in this neuropsychiatric population. Therefore, we recommend that a multidisciplinary (eg, pharmacotherapeutic, psychoeducational, and/or psychotherapeutic) approach to treatment be taken with depressed PD patients.

    An economic analysis was performed on treatment options for pig manure in Ireland. Costs were based on a 500 sow integrated pig farm producing 10,500 m(3) of manure per year at 4.8% dry matter. The anaerobic digestion of pig manure and grass silage (1:1; volatile solids basis) was unviable under the proposed tariffs, with costs at € 5.2 m(-3) manure. Subsequent solid-liquid separation of the digestate would cost an additional € 12.8 m(-3) manure. The treatment of the separated solid fraction by composting and of the liquid fraction by integrated constructed wetlands, would add € 2.8 and € 4.6 m(-3) manure, respectively to the treatment costs. The cost analysis presented showed that the technologies investigated are currently not cost effective in Ireland. Transport and spreading of raw manure, at € 4.9 m(-3) manure (15 km maximum distance from farm) is the most cost effective option.

    Anorexia nervosa (AN) is a severe psychiatric disorder with high rates of morbidity, comorbidity and mortality, which in a subset of patients (21%) takes on a chronic course. Since an evidence based treatment for AN is scarce, it is crucial to investigate new treatment options, preferably focused on influencing the underlying neurobiological mechanisms of AN. The objective of the present paper was to review the evidence for possible neurobiological correlates of AN, and to hypothesize about potential targets for Deep brain stimulation (DBS) as a treatment for chronic, therapy-refractory AN. One avenue for exploring new treatment options based on the neurobiological correlates of AN, is the search for symptomatologic and neurobiologic parallels between AN and other compulsivity- or reward-related disorders. As in other compulsive disorders, the fronto-striatal circuitry, in particular the insula, the ventral striatum (VS) and the prefrontal, orbitofrontal, temporal, parietal and anterior cingulate cortices, are likely to be implicated in the neuropathogenesis of AN. In this paper we will review the few available cases in which DBS has been performed in patients with AN (either as primary diagnosis or as comorbid condition). Given the overlap in symptomatology and neurocircuitry between reward-related disorders such as obsessive compulsive disorder (OCD) and AN, and the established efficacy of accumbal DBS in OCD, we hypothesize that DBS of the nucleus accumbens (NAc) and other areas associated with reward, e.g. the anterior cingulated cortex (ACC), might be an effective treatment for patients with chronic, treatment refractory AN, providing not only weight restoration, but also significant and sustained improvement in AN core symptoms and associated comorbidities and complications. Possible targets for DBS in AN are the ACC, the ventral anterior limb of the capsula interna (vALIC) and the VS. We suggest conducting larger efficacy studies that also explore the

    Aim: To assess the efficacy of percutaneous osteoid osteoma treatment using a combination of radiofrequency ablation (RFA) and alcohol ablation with regard to technical and long-term clinical success. Materials and methods: From December 2001 to November 2004, RFA and subsequent alcohol ablation was performed on 54 patients with osteoid osteoma, diagnosed clinically using radiography, computed tomography (CT) and symptoms. Under general anaesthesia, treatment was performed via percutaneous access under thin section (2 mm) spiral CT guidance in all cases with an 11 G radiofrequency-compatible coaxial needle and 2 mm coaxial drill system and 1.0 cm active tip 17 G non-cooled radiofrequency needle. RFA was performed at 90 {sup o}C for a period of 6 min. After needle removal, 0.5-1.0 ml absolute alcohol (99.8% concentration) was injected directly into the nidus using a 20 G needle. Patients were discharged within 24 h and followed up clinically (at 1 week, 1 month and every 3 months thereafter). Results: The technical success rate was 100%. Complications occurred in two patients consisting of local mild cellulitis in entry site and peripheral small zone paresthesia on the anterior part of leg. The follow-up period range was 13-48 months (mean {+-} SD, 28.2 {+-} 7.4 months). Prompt pain relief and return to normal activities were observed in 52 of 54 patients. Recurrent pain occurred in two patients after a 1 and 3 months period of being pain free, respectively; a second RFA and alcohol ablation was performed achieving successful results. Primary and secondary clinical success rates were 96.3% (52/54 patients) and 100% (2/2 patients), respectively. Conclusion: Percutaneous osteoid osteoma treatment with combination of radiofrequency and alcohol ablation is safe, effective and minimally invasive with high primary and secondary success rates. Persistent or recurrent lesions can be effectively re-treated.

FMS leads to high disability levels, poor quality of life, and extensive use of medical care. Effective pharmacological treatment options are rare, and treatment effects are often of limited duration. Duloxetine is a new selective serotonin and norepinephrine reuptake inhibitor that is licensed for the treatment of pain in diabetic neuropathy. So far two randomized, placebo-controlled trials have investigated the short-term safety and efficacy of duloxetine 60 mg/day and 120 mg/day in patients suffering from FMS over a period of 12 weeks. Both dosages were superior to placebo in pain relief, and improvement in quality of life and depressive symptoms. The analgesic effect was largely independent of the antidepressant action of duloxetine. The higher dose of 120 mg/day further reduced the tender point count and elevated the tender point pain thresholds. Only mild to moderate adverse effects were reported. Duloxetine 60 mg/day and 120 mg/day has proven to be beneficial in the treatment of FMS symptoms. As true for other antidepressants further studies are needed to assess the long-term efficacy and safety of duloxetine as an additional pharmacological treatment option in FMS.Keywords: fibromyalgia syndrome, duloxetine, antidepressant, review, SNRI

    Bipolar disorders of types I and II, even when treated by currently standard options, show a marked excess of depressive morbidity. Treated, type I patients in mid-course or from the onset of illness are ill, overall, 50 % of weeks of follow-up, and 75 % of that unresolved morbidity is depressive. Currently widely held impressions are that bipolar depression typically is poorly responsive to antidepressants, that treatment-resistant depression (TRD) is characteristic of the disorder, and that risk of mania with antidepressant treatment is very high. However, none of these views is supported consistently by available research. TRD may be more prevalent in bipolar than unipolar mood disorders. Relatively intense research attention is directed toward characteristics and treatments of TRD in unipolar depression, but studies of bipolar TRD are uncommon. We found only five controlled trials, plus 10 uncontrolled trials, providing data on a total of 13 drug treatments, all of which involved one or two trials, in 87 % as add-ons to complex, uncontrolled regimens. In two controlled trials, ketamine was superior to placebo but it is short-acting and not orally active; pramipexole was weakly superior to placebo in one controlled trial; three other drugs failed to outperform controls. Other pharmacotherapies are inadequately evaluated and nonpharmacological options are virtually untested in bipolar TRD. The available research supports the view that antidepressants may be effective in bipolar depression provided that currently agitated patients are excluded, that risk of mania with antidepressants is only moderately greater than risk of spontaneous mania, and that bipolar TRD is not necessarily resistant to all treatments.

    This paper provides a broad review of the extant literature involving the treatment of sleeplessness in older adults with insomnia. First, background information (including information regarding key issues in late-life insomnia and epidemiology of late-life insomnia) pertinent to achieving a general understanding of insomnia in the elderly is presented. Next, theories of insomnia in older adults are examined and discussed in relation to treatment of insomnia in late-life. With a general knowledge base provided, empirical evidence for both pharmacological (briefly) and psychological treatment options for insomnia in late-life are summarized. Recent advances in the psychological treatment of insomnia are provided and future directions are suggested. This review is not meant to be all-inclusive; however, it is meant to provide professionals across multiple disciplines (physicians; psychologists; applied and basic researchers) with a mix of breadth and depth of knowledge related to insomnia in late-life. It is our hope that readers will see the evidence in support of psychological treatments for late-life insomnia, and the utility in continuing to investigate this treatment modality. PMID:22323897

    The lower eyelid can be a challenging area in facial rejuvenation. While lower eyelid bags are commonly the reason that patients present for lower eyelid rejuvenation, a separate entity known as a tear trough deformity may occur in conjunction with lower eyelid bags or alone. In this article, the authors outline the current understanding of the tear trough anatomy; describe multiple classification systems, which provide an objective means of evaluating the deformity and aid the surgeon in choosing appropriate treatment options; and review surgical and nonsurgical techniques for correcting the tear trough deformity. Treatment options include hyaluronic acid filler, fat grafting, skeletal implants, and fat transposition. Each procedure is associated with advantages and disadvantages, and each should be considered more complex than traditional lower blepharoplasty alone. While lower blepharoplasty removes excess fat and may tighten the anterior lamella, tear trough procedures require the addition of volume to the underlying depression. These procedures requiring release of the ligamentous structures and orbicularis (of which the tear trough is composed), as well as fat transposition or fat grafting, are associated with additional complications, which are also reviewed.

Initially, dietary modifications are encouraged, which include frequent and small semisolid-based meals. Promotility medications, like erythromycin, and antiemetics, like prochlorperazine, are offered for symptom relief. In patients who are refractory to pharmacologic treatment, more invasive options, such as intrapyloric botulinum toxin injections, placement of a jejunostomy tube, or implantation of a gastric stimulator, can be considered. Hemin therapy and gastric electric stimulation are emerging treatment options that are still at different stages of research.

    2016-06-15

    Rosacea is a common chronic skin condition that displays a broad diversity of clinical manifestations. Although the pathophysiological mechanisms of the four subtypes are not completely elucidated, the key elements often present are augmented immune responses of the innate and adaptive immune system, and neurovascular dysregulation. The most common primary feature of all cutaneous subtypes of rosacea is transient or persistent facial erythema. Perilesional erythema of papules or pustules is based on the sustained vasodilation and plasma extravasation induced by the inflammatory infiltrates. In contrast, transient erythema has rapid kinetics induced by trigger factors independent of papules or pustules. Amongst the current treatments for facial erythema of rosacea, only the selective α2-adrenergic receptor agonist brimonidine 0.33% topical gel (Mirvaso®) is approved. This review aims to discuss the potential causes, different pathophysiologies and current treatment options to address the unmet medical needs of patients with facial erythema of rosacea.

    Sleep disorders in children can compromise quality of life of both children and families and chronic sleep deprivations is associated with poorer developmental outcome, overweight and behavioral disturbances. Clinicians should incorporate questions about sleep into their routine health assessment, and the assessment of insomnia should follow a medical approach primary and secondary contributing factors should be assessed, as well as maladaptive behaviors related to sleep. A careful examination of sleep/wake schedule, abnormal movements or behavior during sleep, and daytime consequences of sleep disruption or deprivation is mandatory. Sleeping environment, and bedtime routines should be examined to identify behavioral issues related to sleep. Polysomnography is not routinely indicated for children with insomnia, but actigraphy can give an objective estimation of sleep parameters. The Authors propose a new classification of pediatric insomnia, based on both genetic and clinical aspects, and suggest specific treatment options, including sleep hygiene, behavioral strategies and pharmacological treatment.

This review discusses the current pathophysiological concepts of migraine and migraine aura, such as a possible brainstem dysfunction and cortical spreading depression. Acute and preventive migraine treatment approaches are briefly covered with a focus on shortcomings of the currently available treatment options. A number of different receptors, such as calcitonin gene-related peptide (CGRP, TRPV1 and glutamate receptors, are currently being targeted by potential novel migraine therapeutics. The prospects of this research are exciting and are likely to improve patient care.

PD is not an uncommon disorder, with recent epidemiologic studies documenting a prevalence of 3–9% of adult men affected. The actual prevalence of PD may be even higher. It is often associated with penile pain, anatomical deformities in the erect penis, and difficulty with intromission. As the definitive pathophysiology of PD has not been completely elucidated, further basic research is required to make progress in the understanding of this enigmatic condition. Similarly, research on effective therapies is limited. Currently, nonsurgical treatments are used for those men who are in the acute stage of PD, whereas surgical options are reserved for men with established PD who cannot successfully penetrate. Intralesional treatments are growing in clinical popularity as a minimally invasive approach in the initial treatment of PD. A surgical approach should be considered when men with PD do not respond to conservative, medical, or minimally invasive therapies for approximately 1 year and cannot have satisfactory sexual intercourse. As scientific breakthroughs in the understanding of the mechanisms of this disease process evolve, novel treatments for the many men suffering with PD are anticipated.Keywords: oral therapy, intralesional treatment, topical therapy, extracorporeal shockwave therapy, traction devices, plication, incision and grafting, penile prosthesis.

    26 patients were included into HIFU and 74 group in group of the combined treatment (TURP+HIFU. Selection criteria for HIFU ablation were the localized cancer of a prostate concerning which earlier it wasn't carried out treatments, and level of a PSA at the time of statement of the diagnosis 15 ng/ml. All patients corresponding to these by criteria, were considered as candidates for treatment and inclusion in the analysis. The nadir and stability of PSA, the histologic conclusion, IPSS, quality of life and complication were estimated at time of postoperative supervision. Results: Statistically significant influence of a combination TURP+HIFU for the term of transurethral drainage of a bladder (a median of 40 days against 7 days, incontience frequency (15.4% against 6.9%, infections of urinary ways (47.9% against 11.4% and IPSS change during the postoperative period (on the average 8.91 against 3.37 is noted. During the short period of supervision it wasn't observed considerable changes in relation to efficiency: in HIFU group the frequency of repeated sessions made 25%, in TUR/HIFU group 4%. Conclusion: HIFU therapy is modern, minimum invasive method of a cancer therapy of a prostate. The combination of a transurethral resection and HIFU ablation significantly reduces the frequency of the complications connected with treatment. Maintaining the patient after combined TURP and HIFU ablation is comparable with maintaining the patient after usual TURP.

    Full Text Available Daniel E Spratt, Nancy LeeDepartment of Radiation Oncology, Memorial Sloan-Kettering Cancer Center, New York, NY, USAAbstract: In this article, we focus on the current and emerging treatments in nasopharyngeal cancer (NPC. A detailed evolution of the current standard of care, and new techniques and treatment options will be reviewed. Intergroup 0099 established the role for chemoradiotherapy (chemo-RT in the treatment of nasopharyngeal carcinoma. Multiple randomized Phase III trials have shown the benefit of chemo-RT; however, none of these studies utilized modern radiotherapy (RT techniques of intensity-modulated radiation therapy (IMRT. IMRT has the ability to deliver high doses of radiation to the target structures while sparing adjacent bystander healthy tissues, and has now become the preferred RT treatment modality. Chemotherapy also has had a shifting paradigm of induction and/or adjuvant chemotherapy combined with RT alone, to the investigation with concurrent chemo-RT. New treatment options including targeted monoclonal antibodies and small molecule tyrosine kinase inhibitors are being studied in NPC. These new biologic therapies have promising in vitro activity for NPC, and emerging clinical studies are beginning to define their role. RT continues to expand its capabilities, and since IMRT and particle therapy, specifically intensity-modulated proton therapy (IMPT, has reports of impressive dosimetric efficacy in-silica. Adaptive RT is attempting to reduce toxicity while maintaining treatment efficacy, and the clinical results are still in their youth. Lastly, Epstein–Barr virus (EBV DNA has recently been studied for prediction of tumor response and its use as a biomarker is increasingly promising to aid in early detection as well as supplementing the current staging system. RT with or without chemotherapy remains the standard of care for nasopharyngeal carcinoma. Advances in RT technique, timing of chemotherapy, biologically

    Limits of treatment in chronic inflammatory demyelinating poly(radiculo)neuropathies (CIDP) patients are better known thanks to recent Cochrane reviews. (1) Randomized controlled trials have only focused on short-term effects, but most patients need long-term therapy, (2) There are three proven effective treatments available (prednisone; intravenous immunoglobulin or IVIg and plasma exchange or PE) which are useful in more than 60 p. 100 of patients, (3) New open studies indicated possible efficacy for mycophenolate, rituximab, etanercept, ciclosporine and interferons, and (4) Whether CIDP variants need specific treatment is still unknown. Many CIDP patients need treatment for years. The fear of side effects during long-term steroid treatment, the high costs of IVIg, the necessity for specialized equipment and the invasive nature of PE, are important factors determining the choice for one of these treatments. In most up-to-date treatment options, patients are initially treated with IVIg at a dosage of 2 g/kg administered for 25 days, clinical improvement can be judged within 10 days. The percentage of patients responding seems to be approximately 70 percent, with a very high chance (approximately 85 percent) that repeated administration of IVIg will be necessary, explaining why most neurologists add an immunosuppressive drug at this stage, but there is no consensus concerning the best drug to be used. Combinations of drugs are most likely to be useful in the next future, using IVIg, prednisone, and a immunosuppressor agent, such as mycophenolate, rituximab, etanercept, or ciclosporine. General measures to rehabilitate patients and to manage symptoms like fatigue and other residual findings are important.

    2016-02-01

    Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease characterized by recurrent inflammatory nodules mostly located in the armpits and groin. Over the years multiple treatments for HS have been proposed; however, to date a cure is still lacking. In this update we provide an overview of most drug treatments reported on for HS, where possible with their mode of action and side effects. In mild cases, clindamycin lotion or resorcinol cream have proven effective. Tetracyclines are a first-line systemic option in more widespread or severe cases, followed by the combination of clindamycin and rifampicin. However, the recurrence rate is high after discontinuation of clindamycin plus rifampicin combination therapy. Long-term treatment with retinoids, especially acitretin is feasible, although teratogenicity has to be taken into account in females of reproductive age. Multiple anti-inflammatory drugs have been suggested for HS, such as dapsone, fumarates or cyclosporine. However, their effectiveness in HS is based on small case series with varying results. If most common treatments have failed, biologics (e.g., infliximab or adalimumab) are the next step. Although not addressed in this review, surgical interventions are often needed to achieve remission. PMID:26659474

    2015-11-01

    Myelodysplastic syndromes (MDS) are typical diseases of the elderly, with a median age of 68-75 years at initial diagnosis. Demographic changes producing an increased proportion of elderly in our societies mean the incidence of MDS will rise dramatically. Considering the increasing number of treatment options, ranging from best supportive care to hematopoietic stem cell transplantation (HSCT), decision making is rather complex in this cohort of patients. Moreover, aspects of the aging process also have to be considered in therapy planning. Treatment of elderly MDS patients is dependent on the patient's individual risk and prognosis. Comorbidities play an essential role as predictors of survival and therapy tolerance. Age-adjusted models and the use of geriatric assessment scores are described as a basis for individualized treatment algorithms. Specific treatment recommendations for the different groups of patients are given. Currently available therapeutic agents, including supportive care, erythropoiesis-stimulating agents (ESAs), immune-modulating agents, hypomethylating agents, and HSCT are described in detail and discussed with a special focus on elderly MDS patients. The inclusion of elderly patients in clinical trials is of utmost importance to obtain data on efficacy and safety in this particular group of patients. Endpoints relevant for the elderly should be integrated, including maintenance of quality of life and functional activities as well as evaluation of use of healthcare resources.

    Isolation of the pulmonary veins by applying radiofrequency is an effective treatment for atrial fibrillation. One of the potential complications with higher clinical compromise utilizing this invasive technique is the occurrence of stenosis of one or more pulmonary veins. This complication can be treated by angioplasty with or without stent implantation, with an adequate clinical improvement, but with a high rate of restenosis.

    Full Text Available Abstract Background Threatened miscarriage involves vaginal bleeding in a pregnancy that remains viable. This is a common early pregnancy complication with increased risk factors for early pregnancy loss, preterm premature rupture of membranes (PPROM, preterm delivery, low birth weight babies and maternal antepartum haemorrhage. Currently there are no recommended medical treatment options, rather women receive advice that centres on a 'wait and see' approach. For women with a history of unexplained recurrent miscarriage providing supportive care in a subsequent pregnancy improves live birthing outcomes, but the provision of supportive care to women experiencing threatened miscarriage has to date not been examined. Discussion While it is known that 50-70% of miscarriages occur due to chromosomal abnormalities, the potential for therapeutic intervention amongst the remaining percentage of women remains unknown. Complementary and alternative medicine (CAM therapies have the potential to provide supportive care for women presenting with threatened miscarriage. Within fertility research, acupuncture demonstrates beneficial hormonal responses with decreased miscarriage rates, raising the possibility acupuncture may promote specific beneficial effects in early pregnancy. With the lack of current medical options for women presenting with threatened miscarriage it is timely to examine the possible treatment benefits of providing CAM therapies such as acupuncture. Summary Despite vaginal bleeding being a common complication of early pregnancy there is often reluctance from practitioners to discuss with women and medical personal how and why CAM may be beneficial. In this debate article, the physiological processes of early pregnancy together with the concept of providing supportive care and acupuncture are examined. The aim is to raise awareness and promote discussion as to the beneficial role CAM may have for women presenting with threatened miscarriage.

    Purpose: To compare the safety of image-guided percutaneous cryoablation and radiofrequency ablation in the treatment of hepatocellular carcinoma in patients with cirrhosis. Materials and methods: This retrospective HIPAA-compliant study received institutional review board approval. Forty-two adult patients with cirrhosis underwent image-guided percutaneous ablation of hepatocellular carcinoma from 2003 to 2011. Twenty-five patients underwent 33 cryoablation procedures to treat 39 tumors, and 22 underwent 30 radiofrequency ablation procedures to treat 39 tumors. Five patients underwent both cryoablation and radiofrequency ablation procedures. Complication rates and severity per procedure were compared between the ablation groups. Potential confounding patient, procedure, and tumor-related variables were also compared. Statistical analyses included Kruskal–Wallis, Wilcoxon rank sum, and Fisher's exact tests. Two-sided P-values <0.05 were considered significant. Results: The overall complication rates, 13 (39.4%) of 33 cryoablation procedures versus eight (26.7%) of 30 radiofrequency ablation procedures and severe/fatal complication rates, two (6.1%) of 33 cryoablation procedures versus one (3.3%) of 30 radiofrequency ablation procedures, were not significantly different between the ablation groups (both P = 0.26). Severe complications included pneumothoraces requiring chest tube insertion during two cryoablation procedures. One death occurred within 90 days of a radiofrequency ablation procedure; all other complications were managed successfully. Conclusion: No significant difference was seen in the overall safety of image-guided percutaneous cryoablation and radiofrequency ablation in the treatment of hepatocellular carcinoma in patients with cirrhosis.

    Sarcoidosis is typically characterized as a non-caseating granulomatous disease that has the ability to affect multiple different organ systems. Although extra-thoracic sarcoidosis can occur in the presence and also without lung involvement, isolated extra-pulmonary disease is rare. The liver is the third most commonly affected organ system after the lungs and lymph nodes. When discussing hepatic sarcoidosis it is important to keep in mind that many patients in this population may not present as one would typically expect since most of the patients are asymptomatic or have mild presentations. Therefore, the diagnosis can be difficult at times since no single laboratory or imaging study can definitively diagnose this systemic disease. In the rare case of some patients where there is difficulty in discerning between different pathologies, the use of image-guided tissue biopsy may be necessary to establish a diagnosis. At the current time, there are no clear guidelines for the management of hepatic sarcoidosis and are mostly dependent on a patient's clinical status at time of presentation. The current body of research in regard to treatment suggests steroids to be the mainstay of therapy. However, there is a role for additional immunosuppressive therapy in cases where the initial treatment is refractory to steroids. In this manuscript, we discussed the pathogenesis of liver sarcoidosis and context of its presentation. In addition, the differential diagnosis and imaging evaluation in this population is discussed. Finally, treatment options are reviewed in setting of previous studies for liver sarcoidosis. PMID:27175775

    Minimally invasive interventional therapies are evolving rapidly and their use for the treatment of solid tumours is becoming more extensive. The in situ destruction of solid tumours by such therapies is thought to release antigens that can prime an antitumour immune response. In this review, we offer an overview of the current evidence for immune response activation associated with the utilisation of the main thermal and non-thermal ablation therapies currently in use today. This is followed by an assessment of the hypothesised mechanisms behind this immune response priming and by a discussion of potential methods of harnessing this specific response, which may subsequently be applicable in the treatment of cancer patients. References were identified through searches of PubMed/MEDLINE and Cochrane databases to identify peer-reviewed original articles, meta-analyses and reviews. Papers were searched from 1850 until October 2014. Articles were also identified through searches of the authors' files. Only papers published in English were reviewed. Thermal and non-thermal therapies have the potential to stimulate antitumour immunity although the current body of evidence is based mostly on murine trials or small-scale phase 1 human trials. The evidence for this immune-modulatory response is currently the strongest in relation to cryotherapy and radiotherapy, although data is accumulating for related ablative treatments such as high-intensity focused ultrasound, radiofrequency ablation and irreversible electroporation. This effect may be greatly enhanced by combining these therapies with other immunostimulatory interventions. Evidence is emerging into the immunomodulatory effect associated with thermal and non-thermal ablative therapies used in cancer treatment in addition to the mechanism behind this effect and how it may be harnessed for therapeutic use. A potential exists for treatment approaches that combine ablation of the primary tumour with control and possible

    Full Text Available Primary ovarian insufficiency (POI, commonly referred to premature ovarian failure, is defined as ovarian failure before the age of 40 years. It is the loss of ovarian function caused by a process directly affecting ovaries. Cancer therapy which includes surgery, radiotherapy, and chemotherapy influence ovarian function, leading to premature menopause and loss of fertility. POI is idiopathic in most cases (74-90%. The known causes, in addition to anticancer treatment, are other processes like chromosomal abnormalities, autoimmunity, and natural aging can result in secondary ovarian failure, which is detected by an increase in serum gonadotropin levels (FSH and LH. There are evident risks of POI in women treated for cancer. Those who receive anticancer treatments have an increased risk of developing POI. There by, anticancer drugs and radiation therapy are considered as the most common toxins of ovaries. Although cancer incidence rates in women less than 50 years old continue to increase during recent years, mortality rates are dramatically decreasing due to modern advances in treatment. Increasing numbers of survivors are now confronted with the long-term consequences of exposure to these treatments. The pool of primordial follicles in the ovary is fixed and any injury to the ovary can potentially reduce this ovarian reserve, effectively advancing the patient’s reproductive age, thus narrowing the window of reproductive opportunity. Ovarian failure occurs in a significant percentage of childhood cancer survivors and many of them will seek care for reproductive dysfunction. Nevertheless, Embryo cryopreservation, oocyte cryopreservation, ovary tissue cryopreservation, ovarian suppression and oophoro-pexy are some options to preserve fertility in these groups. As a result, having foreknowledge of potential treatment related ovarian failure will allow the physician to give a better counsel to patients and their family regarding the importance and

    Hepatocellular cancer ranks fifth among cancers andis related to chronic viral hepatitis, alcohol abuse,steatohepatitis and liver autoimmunity. Surgical resectionand orthotopic liver transplantation have curativepotential, but fewer than 20% of patients are suitablecandidates. Interventional treatments are offered to thevast majority of patients. Radiofrequency (RFA) andmicrowave ablation (MWA) are among the therapeuticmodalities, with similar indications which include thepresence of up to three lesions, smaller than 3 cm in size,and the absence of extrahepatic disease. The therapeuticeffect of both methods relies on thermal injury, but MWAuses an electromagnetic field as opposed to electricalcurrent used in RFA. Unlike MWA, the effect of RFA ispartially limited by the heat-sink effect and increasedimpedance of the ablated tissue. Compared with RFA,MWA attains a more predictable ablation zone, permitssimultaneous treatment of multiple lesions, and achieveslarger coagulation volumes in a shorter procedural time.Major complications of both methods are comparableand infrequent (approximately 2%-3%), and theyinclude haemorrhage, infection/abscess, visceral organinjury, liver failure, and pneumothorax. RFA may incurthe additional complication of skin burns. Nevertheless,there is no compelling evidence for differences in clinicaloutcomes, including local recurrence rates and survival.

    The traditional surgical treatment of an incompetent great saphenous vein (GSV) and small saphenous vein (SSV) is challenged by endovenous techniques. Bipolar radio frequency induced thermo therapy (RFITT) is a new endovenous treatment, which occludes the vein by using the venous wall as a conductor. Linear endovenous energy densitiy (LEED) describes the amount of energy used for vein closure. Material/methods: From March 2007 till April 2009, two cohorts (23 W and 20 W) were compared, respectively 280 and 178 patients. GSV and SSV were separately analyzed. Follow-up was performed at 3 weeks and 1 year post-operatively with duplex ultrasound, to assess vein closure and perioperative complaints. A visual analog scale (VAS) pain score (range 0-10) was documented. For patients operated after October 2008 follow-up was performed at least 6 months after surgery. Results: 528 GSV and 76 SSV were treated. For the GSV a significant difference in LEED 40.8 17.1 in the 20 W cohort was found, resulting in higher occlusion rates 90.6% compared to 82.7% after 3 weeks. Follow-up of 1 year in the 20 W cohort showed 88.7% occlusion. Multivariate analysis showed that pullback speed (OR 3.7, CI 1.1-12.4) and CEAP classification (OR 3.1, CI 1.7-5.6) were significant predictors for vein occlusion. Despite a higher LEED, post-operative complaints were not significantly worse. Conclusion: RFITT is a safe and effective method to treat incompetent saphenous veins. Slower pullback speed with higher LEED results in higher closure rates without causing more pain.

    Radiofrequency ablation (RFA), with or without endoscopic mucosal resection (EMR), is a safe, effective, and durable treatment option for Barrett esophagus (BE)-associated dysplasia (DYS), but few studies have identified predictors of treatment failure in BE-associated intramucosal adenocarcinoma (IMC). The aim of this study was to determine the rate of IMC eradication when using RFA±EMR and to identify clinical and pathologic predictors of treatment failure. A retrospective review of medical records and a central review of index histologic parameters were performed for 78 patients who underwent RFA±EMR as the primary treatment for biopsy-proven IMC at 4 academic tertiary medical centers. Complete eradication (CE) (absence of IMC/DYS on first follow-up endoscopy) was achieved in 86% of patients, and durable eradication (DE) (CE with no recurrence of IMC/DYS until last follow-up) was achieved in 78% of patients, with significant variation between the 4 study sites (P=0.03 and 0.09 by analysis of variance for DE and CE, respectively). Use of EMR before RFA significantly reduced the risk for treatment failure for IMC/DYS (hazard ratio, 0.15; 95% confidence interval, 0.05-0.48; P=0.001), whereas IMC involving ≥50% of the columnar metaplastic area on index examination significantly increased the risk for treatment failure (hazard ratio, 4.24; 95% confidence interval, 1.53-11.7; P=0.005). Endoscopic and pathologic factors associated with treatment failure in BE-associated IMC treated with RFA±EMR may help identify the subset of IMC patients for whom a more aggressive initial approach may be justified.

    Our inability to adequately treat many patients with refractory epilepsy caused by focal cortical dysplasia (FCD), surgical inaccessibility and failures are significant clinical drawbacks. The targeting of physiologic features of epileptogenesis in FCD and colocalizing functionality has enhanced completeness of surgical resection, the main determinant of outcome. Electroencephalography (EEG)-functional magnetic resonance imaging (fMRI) and magnetoencephalography are helpful in guiding electrode implantation and surgical treatment, and high-frequency oscillations help defining the extent of the epileptogenic dysplasia. Ultra high-field MRI has a role in understanding the laminar organization of the cortex, and fluorodeoxyglucose-positron emission tomography (FDG-PET) is highly sensitive for detecting FCD in MRI-negative cases. Multimodal imaging is clinically valuable, either by improving the rate of postoperative seizure freedom or by reducing postoperative deficits. However, there is no level 1 evidence that it improves outcomes. Proof for a specific effect of antiepileptic drugs (AEDs) in FCD is lacking. Pathogenic mutations recently described in mammalian target of rapamycin (mTOR) genes in FCD have yielded important insights into novel treatment options with mTOR inhibitors, which might represent an example of personalized treatment of epilepsy based on the known mechanisms of disease. The ketogenic diet (KD) has been demonstrated to be particularly effective in children with epilepsy caused by structural abnormalities, especially FCD. It attenuates epigenetic chromatin modifications, a master regulator for gene expression and functional adaptation of the cell, thereby modifying disease progression. This could imply lasting benefit of dietary manipulation. Neurostimulation techniques have produced variable clinical outcomes in FCD. In widespread dysplasias, vagus nerve stimulation (VNS) has achieved responder rates >50%; however, the efficacy of noninvasive

    Full Text Available Interspinous process decompression is a minimally invasive implantation procedure employing a stand-alone interspinous spacer that functions as an extension blocker to prevent compression of neural elements without direct surgical removal of tissue adjacent to the nerves. The Superion® spacer is the only FDA approved stand-alone device available in the US. It is also the only spacer approved by the CMS to be implanted in an ambulatory surgery center. We computed the within-group effect sizes from the Superion IDE trial and compared them to results extrapolated from two randomized trials of decompressive laminectomy. For the ODI, effect sizes were all very large (>1.0 for Superion and laminectomy at 2, 3, and 4 years. For ZCQ, the 2-year Superion symptom severity (1.26 and physical function (1.29 domains were very large; laminectomy effect sizes were very large (1.07 for symptom severity and large for physical function (0.80. Current projections indicate a marked increase in the number of patients with spinal stenosis. Consequently, there remains a keen interest in minimally invasive treatment options that delay or obviate the need for invasive surgical procedures, such as decompressive laminectomy or fusion. Stand-alone interspinous spacers may fill a currently unmet treatment gap in the continuum of care and help to reduce the burden of this chronic degenerative condition on the health care system.

    Full Text Available Prakash Abraham1, Shamasunder Acharya21Department of Endocrinology, Aberdeen Royal Infirmary, Aberdeen, UK; 2Department of Endocrinology, John Hunter Hospital, New Lambton NSW, AustraliaAbstract: Radioiodine, antithyroid drugs and surgery have been well established therapies for Graves’ hyperthyroidism for several decades. However there remain large variations in practice among physicians in the preferred modality and the method of administration. Patient choice and perceptions also play a big role in the choice of treatment. Radioiodine may be given using fixed high doses or by calculated doses following uptake studies. The risks of radioiodine including eye disease and the role of prophylactic steroid therapy are discussed. The commonly used antithyroid drugs include carbimazole, methimazole and propylthiouracil; however a number of other agents have been tried in special situations or in combination with these drugs. The antithyroid drugs may be given in high (using additional levothyroxine in a block–replace regimen or low doses (in a titration regimen. This review examines the current evidence and relative benefits for these options as well as looking at emerging therapies including immunomodulatory treatments such as rituximab which have come into early clinical trials. The use of antithyroid therapies in special situations is also discussed as well as clinical practice issues which may influence the choices.Keywords: Graves’ hyperthyroidism, radioiodine, antithyroid drugs, methimazole, propylthiouracil

    The application of therapeutic ultrasound for the treatment of atrial fibrillation (AF) is investigated. The results of theoretical and experimental investigation of ultrasound ablation catheter are presented. The major components of the catheter are the high power cylindrical piezoelectric element and parabolic balloon reflector. Thermal elevation in the ostia of pulmonary veins is achieved by focusing the ultrasound beam in shape of a torus that transverses the myocardial tissue. High intensity ultrasound heating in the focal zone results in a lesion surrounding the pulmonary veins that creates an electrical conduction blocks and relief from AF symptoms. The success of the ablation procedure largely depends on the correct choice of reflector geometry and ultrasonic power. We present a theoretical model of the catheter’s acoustic field and bioheat transfer modeling of cardiac lesions. The application of an empirically derived relation between lesion formation and acoustic power is shown to correlate with the experimental data. Developed control methods combine the knowledge of theoretical acoustics and the thermal lesion formation simulations with experiment and thereby establish dosimetry that contributes to a safe and effective ultrasound ablation procedure.

    Thirty-three acromegalic patients were treated with radiotherapy and followed up for at least 3 years (mean 6 years, range 3 to 12). Seventeen had not had previous pituitary ablative therapy and 16 had. The mean GH level for these two groups before radiotherapy was comparable at 98 and 119 mlU/l. The observed frequency of reaching <10 mlU/L was 53% and 75% of patients in the two groups, respectively, the mean observed falls in growth hormone level were 81 and 85% of the initial level, and the calculated exponential decline rate of GH level was 72 and 52% per fyear. Considering all 35 patients, requirement for pituitary hormone replacement therapy increased from 15 patients before radiotherapy to 20 after radiotherapy, being mostly those who had had prior ablative therapies. There were no complications attributable to the radiotherapy treatment. It appears that radiotherapy is equally efficacious whether a prior unsuccessful ablative procedure had been used or not.

    Full Text Available Nilay Kumar,1 David A Calhoun,2 Tanja Dudenbostel21Department of Medicine, 2Division of Cardiovascular Disease, Hypertension and Vascular Biology Program, University of Alabama at Birmingham, Birmingham, AL, USAAbstract: Resistant hypertension (RHTN is an increasingly common clinical problem that is often heterogeneous in etiology, risk factors, and comorbidities. It is defined as uncontrolled blood pressure on optimal doses of three antihypertensive agents, ideally one being a diuretic. The definition also includes controlled hypertension with use of four or more antihypertensive agents. Recent observational studies have advanced the characterization of patients with RHTN. Patients with RHTN have higher rates of cardiovascular events and mortality compared with patients with more easily controlled hypertension. Secondary causes of hypertension, including obstructive sleep apnea, primary aldosteronism, renovascular disease, are common in patients with RHTN and often coexist in the same patient. In addition, RHTN is often complicated by metabolic abnormalities. Patients with RHTN require a thorough evaluation to confirm the diagnosis and optimize treatment, which typically includes a combination of lifestyle adjustments, and pharmacologic and interventional treatment. Combination therapy including a diuretic, a long-acting calcium channel blocker, an angiotensin-converting enzyme inhibitor, a beta blocker, and a mineralocorticoid receptor antagonist where warranted is the classic regimen for patients with treatment-resistant hypertension. Mineralocorticoid receptor antagonists like spironolactone or eplerenone have been shown to be efficacious in patients with RHTN, heart failure, chronic kidney disease, and primary aldosteronism. Novel interventional therapies, including baroreflex activation and renal denervation, have shown that both of these methods may be used to lower blood pressure safely, thereby providing exciting and promising new

    Objective: to evaluate the efficacy and safety of ultrasound ablation of pulmonary veins for treatment of paroxysmal atrial fibrillation. Methods: The study population consisted of 9 patients with 5 males and 4 females enrolled consecutively who had idiopathic paroxysmal atrial fibrillation(AF). The ultrasound balloon was positioned through a special sheath to the orifice of the target vein by a transseptal procedure. The balloon was inflated with contrast-mixed saline (contrast: saline = 1:4) whose volume was decided by the diameter of the target pulmonary vein. The ablation energy was usually set up at 35 to 40 watts with temperature controlled at 60℃. The duration of each ablation was about 120 seconds which was repeated not over 10 times. Results: The average duration of the total procedure was 132±68 min for our patients. The average fluoroscopy time was 33±17 min. With a mean follow-up of 16±8 months after the procedure, AF was completely eliminated in 4 patients without antiarrhythmic drugs. The episodes of atrial fibrillation were eliminated in 2 patients with low dosage of oral amiodarone (0.1, once daily) which was ineffective before the procedure. The frequency of episodes was similar to that before the procedure in 3 patients. There were no complications such as hemopericardium, air embolism and stenosis of the pulmonary veins by angiography, related to the procedure. Conclusion: Ultrasound ablation of the pulmonary veins is a new approach to treat paroxysmal atrial fibrillation. Before we determined its value, we need to do more researches with bigger sample, randomization and comparison design.

  6. Advances in Imaging for Atrial Fibrillation Ablation

    International Nuclear Information System (INIS)

    Over the last fifteen years, our understanding of the pathophysiology of atrial fibrillation (AF) has paved the way for ablation to be utilized as an effective treatment option. With the aim of gaining more detailed anatomical representation, advances have been made using various imaging modalities, both before and during the ablation procedure, in planning and execution. Options have flourished from procedural fluoroscopy, electro anatomic mapping systems, pre procedural computed tomography (CT), magnetic resonance imaging (MRI), ultrasound, and combinations of these technologies. Exciting work is underway in an effort to allow the electro physiologist to assess scar formation in real time. One advantage would be to lessen the learning curve for what are very complex procedures. The hope of these developments is to improve the likelihood of a successful ablation procedure and to allow more patients access to this treatment

    Full Text Available Objective. The study aimed to analyze the results of different concomitant ablation techniques in patients with paroxysmal atrial fibrillation (AF and mitral valve disease according to data of continuous long-term rhythm monitoring. Material and methods. The study was performed between 2009 and 2011 and included 57 patients with mitral valve disease and paroxysmal AF. Patients were randomized in two groups: 31 patient (group I underwent concomitant ablation with defect correction, 26 patients (group II underwent isolated correction of defect. Left atrial (LA radiofrequency ablation was performed using only bipolar devices. All patients underwent implantation of apparatus for continuous heart rhythm monitoring after the primary stage of intervention. Patients with rate of AF less than 0.5% at every follow-up examination were considered to be responders to treatment. Evaluation of atrial transport function was based on analysis of transmitral diastolic flow (E-VTI and A-VTI peaks and pulmonary venous flow. Results. There were no deaths during in-hospital period. Absence of AF was noted in all cases in both groups after completion of surgery. AF paroxysm in early postoperative period required pharmacological (cordarone or electrical cardioversion in 6 patients (19.4% from group I and in 12 patients (46.2% from group II. Control examination was performed in 3, 6 and 12 months. 18 patients (58.1% from group I and 10 patients (38.5% from group II were shown to be free from AF on the first examination. 22 patients (71.0% from group I and only 8 patients (30.8% from group II did not have documented arrhythmia (rate of AF less than 0.5% in 12 months after surgery and were classified as responsive to treatment. 3 patients (11.5% from group II already had persistent AF. Left atrial flutter was noted in 1 patient (3.2% from group I and 1 patient (3.9% from group II had typical flutter. Both patients underwent catheter ablation for atrial flutter, after

    Although surgical resection is still the optimal treatment option for early-stage hepatocellular carcinoma (HCC) in patients with well compensated cirrhosis, thermal ablation techniques provide a valid non-surgical treatment alternative, thanks to their minimal invasiveness, excellent tolerability and safety profile, proven efficacy in local disease control, virtually unlimited repeatability and cost-effectiveness. Different energy sources are currently employed in clinics as physical agents for percutaneous or intra-surgical thermal ablation of HCC nodules. Among them, radiofrequency (RF) currents are the most used, while microwave ablations (MWA) are becoming increasingly popular. Starting from the 90s', RF ablation (RFA) rapidly became the standard of care in ablation, especially in the treatment of small HCC nodules; however, RFA exhibits substantial performance limitations in the treatment of large lesions and/or tumors located near major heat sinks. MWA, first introduced in the Far Eastern clinical practice in the 80s', showing promising results but also severe limitations in the controllability of the emitted field and in the high amount of power employed for the ablation of large tumors, resulting in a poor coagulative performance and a relatively high complication rate, nowadays shows better results both in terms of treatment controllability and of overall coagulative performance, thanks to the improvement of technology. In this review we provide an extensive and detailed overview of the key physical and technical aspects of MWA and of the currently available systems, and we want to discuss the most relevant published data on MWA treatments of HCC nodules in regard to clinical results and to the type and rate of complications, both in absolute terms and in comparison with RFA.

    Keratosis lichenoides chronica (KLC) is a rare dermatological condition characterized by keratotic papules arranged in a parallel linear or reticular pattern and facial lesions resembling seborrheic dermatitis or rosacea. The clinical, histological and therapeutic information on 71 patients with KLC retrieved through a PubMed search plus one our new case were analyzed. KLC affects patients of all ages, with a modest male predominance. Pediatric cases represent about one quarter of patients. Diagnosis is usually delayed and histologically confirmed. All patients have thick, rough and scaly papules and plaques arranged in a linear or reticular pattern, on limbs (>80%) and trunk (about 60%). Face involvement is described in two-thirds of patients. Lesions are usually asymptomatic or mildly pruritic. Other manifestations, such as palmoplantar keratoderma, mucosal involvement, ocular manifestations, nail dystrophy, are reported in 20-30% of patients. Children present more frequently alopecia. No controlled trials are available. Results from small case series or single case reports show that the best treatment options are phototherapy and systemic retinoids, alone or in combination, with nearly half of patients reaching complete remission. Systemic corticosteroids as well as antibiotics and antimalarials are not effective. PMID:26652284

    Familial hypercholesterolemia (FH) is a common genetic disorder that presents with robust increases in low-density lipoprotein cholesterol (LDL-C) and can lead to premature cardiovascular disease. There are heterozygous and homozygous forms. The diagnosis is usually made based on blood cholesterol levels, clinical signs and family history. Genetic testing can be used to confirm the diagnosis. Effective lowering of LDL-C in FH can prevent cardiovascular morbidity and mortality, however, the disease remains greatly underdiagnosed. The mainstay of pharmacologic therapy in FH patients is high-dose statins, which are often combined with other lipid-lowering agents. The homozygous form is mainly treated with lipid apheresis. Guideline-recommended target levels of LDL-C are often not reached, making new treatment options desirable. Four classes of newer lipid-lowering drugs offer promising advances in treating FH, namely the apolipoprotein-B synthesis inhibitors (mipomersen), the microsomal transfer protein inhibitors (lomitapide), the cholesterol ester transfer protein inhibitors (anacetrapib, evacetrapib) and the proprotein convertase subtilisin/kexin type 9 inhibitors (evolocumab, alirocumab). In this review, the available evidence regarding the use of these drugs in patients with FH is discussed, with particular focus on their efficacy and safety.

    SARS (severe acute respiratory syndrome) appeared as the first emerging infectious disease of this century. It is fortunate that the culprit virus can be grown without much difficulty from a commonly used cell line, allowing an unlimited supply of isolates for further molecular studies and leading to the development of sensitive diagnostic assays. How the virus has successfully jumped the species barrier is still a mystery. The superspreading events that occurred within hospital, hotel and high-density housing estate opens a new chapter in the mechanisms and routes of virus transmission. The old practice of quarantine proved to be still useful in controlling the global outbreak. Despite all the available sophisticated tests, alertness with early recognition by healthcare workers and prompt isolation of suspected cases is still the most important step for containing the spread of the infection. Although the rapidly evolving outbreak did not allow the conducting of systematic clinical trails to evaluate treatment options, the accumulated experience on managing SARS patients will improve the clinical outcome should SARS return. Although SARS led to more than 700 deaths worldwide, the lessons learnt have prepared healthcare systems worldwide to face future emerging and re-emerging infections. PMID:16411895

    2012-07-01

    Full Text Available Abstract Background Stereotactic ablative radiotherapy (SABR has emerged as a new treatment option for patients with oligometastatic disease. SABR delivers precise, high-dose, hypofractionated radiotherapy, and achieves excellent rates of local control. Survival outcomes for patients with oligometastatic disease treated with SABR appear promising, but conclusions are limited by patient selection, and the lack of adequate controls in most studies. The goal of this multicenter randomized phase II trial is to assess the impact of a comprehensive oligometastatic SABR treatment program on overall survival and quality of life in patients with up to 5 metastatic cancer lesions, compared to patients who receive standard of care treatment alone. Methods After stratification by the number of metastases (1-3 vs. 4-5, patients will be randomized between Arm 1: current standard of care treatment, and Arm 2: standard of care treatment + SABR to all sites of known disease. Patients will be randomized in a 1:2 ratio to Arm 1:Arm 2, respectively. For patients receiving SABR, radiotherapy dose and fractionation depends on the site of metastasis and the proximity to critical normal structures. This study aims to accrue a total of 99 patients within four years. The primary endpoint is overall survival, and secondary endpoints include quality of life, toxicity, progression-free survival, lesion control rate, and number of cycles of further chemotherapy/systemic therapy. Discussion This study will provide an assessment of the impact of SABR on clinical outcomes and quality of life, to determine if long-term survival can be achieved for selected patients with oligometastatic disease, and will inform the design of a possible phase III study.

    The purpose of this work was to preliminarily investigate the efficacy and safety of high-intensity focused ultrasound treatment of hepatocellular carcinoma and hypersplenism. Nine patients with hepatocellular carcinoma complicated by hypersplenism (5 male and 4 female; median age, 56 years; range, 51-66 years) were treated with ultrasound-guided high-intensity focused ultrasound. Complications were recorded. Laboratory examination and magnetic resonance imaging were used to evaluate the efficacy. After high-intensity focused ultrasound treatment, mean spleen ablation ± SD of 28.76% ± 6.1% was discovered; meanwhile, the white blood cell count, platelet count, and liver function of the patients were substantially improved during the follow-up period. In addition, symptoms such as epistaxis and gingival bleeding were ameliorated or even eliminated, and the quality of life was improved. Follow-up imaging showed a nonperfused volume in the spleen and an absence of a tumor blood supply at the treated lesions in the liver. For the first time to our knowledge, high-intensity focused ultrasound ablation was used to treat hepatocellular carcinoma complicated by hypersplenism. High-intensity focused ultrasound may be an effective and safe alternative for treatment of hepatocellular carcinoma complicated by hypersplenism, but further studies are necessary to clarify the mechanisms.

    The treatment of diseases of the lingual tonsils is still under debate, and surgical interventions are often associated with significant morbidity and complications. The aim of the present study was to evaluate the safety of lingual tonsillectomy using cold ablation (coblation) as a new treatment of lingual tonsil diseases. In this retrospective, bicentric study, we included all patients between 2005 and 2012 who underwent cold ablation (Coblation(®)) of the lingual tonsils. We assessed the frequency of postoperative complications based on the patients' charts. A total of 108 patients (47 ± 13, 6 years) underwent lingual tonsillectomy using coblation. All patients were operated on under general anesthesia as inpatients. Intraoperative complications did not occur. Three patients (2.8%) needed revision surgery due to postoperative hemorrhage, and in one of those cases, three revisions were necessary. There was no postoperative airway compromise and no need for tracheostomy. There was no hypoglossal nerve paralysis, but in the case needing multiple revisions, a weakness of the hypoglossal nerve persisted. In all the cases, oral intake was possible with adequate analgesia. Coblation of the tongue base is a safe procedure with a relatively low rate of postoperative complications. Postoperative hemorrhage is the most relevant complication that occurred in our series of patients. Future studies are needed to evaluate the efficacy of the procedure in the treatment of obstructive sleep apnea.

    Full Text Available Abstract Background In oncologic patients with metastatic spinal disease, the ideal treatment should be well tolerated, relieve the pain, and preserve or restore the neurological function. The combination of fluoroscopic guided radiofrequency ablation (RFA and kyphoplasty may fulfill these criteria. Methods We describe three pathological vertebral fractures treated with a combination of fluoroscopic guided RFA and kyphoplasty in one session: a 62-year-old man suffering from a painful L4 pathological fracture due to a plasmocytoma, a 68-year-old man with a T12 pathological fracture from metastatic hepatocellular carcinoma, and a 71-year-old man with a Th12 and L1 pathological fracture from multiple myeloma. Results The choice of patients was carried out according to the classification of Tomita. Visual analog score (VAS and Oswestry disability index (ODI were used for the evaluation of the functional outcomes. The treatment was successful in all patients and no complications were reported. The mean follow-up was 6 months. Marked pain relief and functional restoration was observed. Conclusion In our experience the treatment of pathologic spinal fractures with combined radiofrequency ablation and balloon kyphoplasty is safe and effective for immediate pain relief in painful spinal lesions in neurologically intact patients.

    AIM: To investigate the treatment efficacy of radiofrequency ablation (RFA) of hepatic malignant tumor and the relevant complications.METHODS: A total of 338 patients with 763 hepatic tumors underwent ultrasound-guided RFA (565 procedures).There were 204 cases of hepatic cellular carcinoma (HCC)with 430 tumors, the mean largest diameter was 4.0 cm.Of them, 48 patients (23.5%) were in stages Ⅰ-Ⅱ (UICC Systems) and 156 (76.5%) in stages Ⅲ-Ⅳ There were 134 cases of metastatic liver carcinoma (MLC), with 333metastases in the liver, the mean diameter was 4.1 cm,the liver metastases of 96 patients (71.6%) came from gastrointestinal tract. Ninety-three percent of the 338patients were treated using the relatively standard protocol. Crucial attention must be paid to monitor the abnormal changes in ultrasound images as well as the vital signs of the patients to find the possible hemorrhage and peripheral structures injury in time. The tumors were considered as ablated completely, if no viability was found on enhanced CT within 24 h or at 1 mo after RFA. These patients were followed up for 3-57 mo.RESULTS: The ablation success rate was 93.3% (401/430tumors) for HCC and was 96.7% (322/333 tumors) for MLC. The local recurrence rate for HCC and MLC was 7.9% (34/430 tumors) and 10.5% (35/333 tumors),respectively. A total of 137 patients (40.5%) underwent 2-11times of repeated ablations because of tumor recurrence or metastasis. The 1st, 2nd, and 3rd year survival rate was84.6%, 66.6%, and 63.1%, respectively;the survival rate from 48 patients of Ⅰ-Ⅱ stage HCC was 93.7%, 80.4%,and 80.4%, respectively. The major complication rate in this study was 2.5% (14 of 565 procedures), which consisted of 5 hemorrhages, 1 colon perforation, 5 injuries of adjacent structures, 2 bile leakages, and 1 skin burn.CONCLUSION: RFA, as a minimally invasive local treatment,has become an effective and relatively safe alternative for the patients of hepatic

    AIM: To evaluate the feasibility and efficacy of percutaneous radiofrequency ablation (RFA) of the feeding artery of hepatocellular carcinoma (HCC) in reducing the blood-flow-induced heat-sink effect of RFA.METHODS: A total of 154 HCC patients with 177 pathologically confirmed hypervascular lesions participated in the study and were randomly assigned into two groups. Seventy-one patients with 75 HCCs (average tumor size, 4.3 ± 1.1 cm) were included in group A, in which the feeding artery of HCC was identified by color Doppler flow imaging, and were ablated with multiple small overlapping RFA foci [percutaneous ablation of feeding artery (PAA)] before routine RFA treatment of the tumor. Eighty-three patients with 102 HCC (average tumor size, 4.1 ± 1.0 cm) were included in group B, in which the tumors were treated routinely with RFA. Contrast-enhanced computed tomography was used as post-RFA imaging, when patients were followed-up for 1, 3 and 6 mo.RESULTS: In group A, feeding arteries were blocked in 66 (88%) HCC lesions, and the size of arteries decreased in nine (12%). The average number of punctures per HCC was 2.76 ± 1.12 in group A, and 3.36 ± 1.60 in group B ( P = 0.01). The tumor necrosis rate at 1 mo post-RFA was 90.67% (68/75 lesions) in group A and 90.20% (92/102 lesions) in group B. HCC recurrence rate at 6 mo post-RFA was 17.33% (13/75) in group A and 31.37% (32/102) in group B ( P = 0.04).CONCLUSION: PAA blocked effectively the feeding artery of HCC. Combination of PAA and RFA significantly decreased post-RFA recurrence and provided an alternative treatment for hypervascular HCC.

Belimumab is the first of a new class of drug targeting B cell-stimulating factors or their receptors to reach the market. Its target, BLyS, also known as BAFF (B cell-activating factor from the tumor necrosis factor family, is a type II transmembrane protein that exists in both membrane-bound and soluble forms. Additionally to a robust rational from murine experiments conducted in lupus prone mice, BLyS circulating levels are increased in SLE patients. After the negative results of a Phase II trial, two Phase III trials met their primary endpoints. Some SLE patients are still refractory to the standard options of care or necessitate prolonged high-dose corticotherapy and/or long-term immunosuppressive regimens. However, some experts still feel that the effect of this biologic might not be clinically relevant and blame the use of the new systemic lupus response index as well as the discrepancies between both trials and the noninclusion of the severe form of the disease as nephritis. In this review, we aim to discuss the characteristics of belimumab, critically evaluate the different steps of its development, and consider its future place in the arsenal against SLE, taking into account the patients’ perspectives.Keywords: systemic lupus erythematosus, belimumab, treatment, monoclonal antibodies, adverse effects, BLyS

  4. Stochastic water quality: Timing and option value of treatment

    An option-pricing model is developed to rank investments that might improve water quality. The model presumes that two investment options exist that have the potential to alter the stochastic drift of a pollutant. The investments have capital and operating costs and are irreversible once constructed. A stochastically evolving pollutant induces damage. The model provides a criterion for determining when it is optimal to adopt the investment with the highest option value. Option value, in this model, measures the expected present value of reduced damage, relative to doing nothing. If the investments are mutually exclusive, it is possible to obtain closed-form solutions for the barriers which would trigger investment. If the investments can be sequentially adopted, a methodology is developed to calculate option values for all possible combinations of adoption dates. To illustrate the option-pricing approach, a stylized analysis of investments to protect New York City's water supply is presented. Watershed management dominates filtration and, in the case of mutually exclusive investments, is initiated when the concentration of phosphorus reaches 22.80 μg/L.

Clinicians involved in the treatment of patients with acute TBI need to be aware of a number of issues, including the incidence and prevalence of early seizures and post-traumatic epilepsy (PTE, comorbidities associated with seizures and anticonvulsant therapies, and factors that can contribute to their emergence. While strong scientific evidence for early seizure prevention in TBI is available for phenytoin (PHT, other antiepileptic medications, eg, levetiracetam (LEV, are also being utilized in clinical settings. The use of PHT has its drawbacks, including cognitive side effects and effects on function recovery. Rates of recovery after TBI are expected to plateau after a certain period of time. Nevertheless, some patients continue to improve while others deteriorate without any clear contributing factors. Thus, one must ask, ‘Are there any actions that can be taken to decrease the chance of post-traumatic seizures and epilepsy while minimizing potential short- and long-term effects of anticonvulsants?’ While the answer is ‘probably,’ more evidence is needed to replace PHT with LEV on a permanent basis. Some have proposed studies to address this issue, while others look toward different options, including other anticonvulsants (eg, perampanel or other AMPA antagonists, or less established treatments (eg, ketamine. In this review, we focus on a comparison of the use of PHT versus LEV in the acute TBI setting and summarize the clinical aspects of seizure prevention in humans with

    Full Text Available The scientific article points out that 40 sessions of HIFU prostate ablation have been performed for estimation of clinical efficiency. Average frequency of influences presents 628±164 impulses; average volume of tissues subjected to influence during one procedure is 33,8±16,3 smi (132 % of prostate volume; average operation time constitutes 150 minutes (from 90 to 200 minutes. During the operation no complications have been occurred. In the first days after the session of HIFU there was a peak of PSA increase and then during 1,5-3 months there was decrease to the lowest index. Minimal PSA level was reached in 10-12 weeks after treatment and it constituted from 0,04 till 1,1 ngml depending on the disease state. Reduction of prostate volume occurred in average from the 30th day of postoperative period and lasted for 6 months, reaching in average 50 % from initial volume. Postoperative period varied from 10 till 16 days and constituted in average 12±0,8 days. Thus application of high-intensity focused ultrasonic ablation allows treating successfully various stages of prostate cancer with minimal number of side-effects and makes possible the early estimation of treatment efficiency

    Full Text Available Many studies state that favourable accounting treatment has been one of the main reasons behind employee stock options. In addition, stock options have recently been the target of growing criticism with a possible influence on incentive effectiveness and outrage costs. In such a perspective, the main purpose of the paper is to explore the impact of IFRS 2 and of the recent financial crisis on stock option compensation. Empirical evidence suggests that: (i IFRS 2 did not have a significant effect on stock option granting, (ii the issue of stock options is less likely to occur during the financial crisis.

  8. Radiofrequency ablation or percutaneous ethanol injection for the treatment of liver tumors

    The liver is a common location of both primary and secondary malignancies.For unresectable liver cancer,many local ablative therapies have been developed.These include e.g.,percutaneous ethanol injection (PEI),percutaneous acetic acid injection,radiofrequency ablation (RFA),cryoablation,microwave ablation,laser-induced thermotherapy,and high-intensity focused ultrasound.RFA has recently gained interest and is the most widely applied thermoablative technique.RFA allows more effective tumor control in fewer treatment sessions compared with PEI,but with a higher rate of complications.However,there are certain circumstances where PEI therapy represents a better strategy to control liver tumors than RFA,especially in situations where RFA is difficult,for example when large vessels surround the tumor.In the context of hepatocellular carcinoma (HCC),both RFA and PEI are feasible and of benefit in non-operable patients.RFA seems superior to PEI in HCC > 2 cm,and the combination of inter-ventions may be of benefit in selected patients.Liver resection is superior to RFA for patients with HCC meeting the Milan criteria,but RFA can be employed in tumors ≤ 3 cm and where there is an increased expected operative mortality.In addition,some lines of evidence indicate that RFA and PEI can be employed as a bridge to liver transplantation.The use of RFA in colorectal liver metastases is currently limited to unresectable disease and for patients unfit for surgery.The aim of this article is to summarize the current status of RFA in the management of liver tumors and compare it to the cheap and readily available technique of PEI.

    Due to modern examination techniques such as multidetector computed tomography and high-field magnetic resonance imaging, the detection rate of renal neoplasms is continually increasing. Even though tumors exceeding 4 cm in diameter rarely metastasize, all renal lesions that are possible neoplasms should be treated. Traditional treatment techniques include radical nephrectomy or nephron-sparing resection, which are increasingly performed laparoscopically. Modern thermal ablation techniques such as hyperthermal techniques like radiofrequency ablation RFA, laser induced thermal ablation LITT, focused ultrasound FUS and microwave therapy MW, as well as hypothermal techniques (cryotherapy) may be a useful treatment option for patients who are unfit for or refuse surgical resection. Cryotherapy is the oldest and best known thermal ablation technique and can be performed laparoscopically or percutaneously. Since subzero temperatures have no antistyptic effect, additional maneuvers must be performed to control bleeding. Percutaneous cryotherapy of renal tumors is a new and interesting method, but experience with it is still limited. Radiofrequency ablation is the most frequently used method. Modern probe design allows volumes between 2 and 5 cm in diameter to be ablated. Due to hyperthermal tract ablation, the procedure is deemed to be safe and has a low complication rate. Although there are no randomized comparative studies to open resection, the preliminary results for renal RFA are promising and show RFA to be superior to other thermal ablation techniques. Clinical success rates are over 90% for both, cryo- and radiofrequency ablation. Whereas laser induced thermal therapy is established in hepatic ablation, experience is minimal with respect to renal application. For lesions of more than 2 cm in diameter, additional cooling catheters are required. MR thermometry offers temperature control during ablation. Microwave ablation is characterized by small ablation volumes

NAFLD is considered a hepatic manifestation of metabolic syndrome and is related to diabetes, insulin resistance, central obesity, hyperlipidemia, and hypertension. Nonalcoholic steatohepatitis (NASH is an entity that describes liver inflammation due to NAFLD. Growing evidence suggests that NAFLD is a multisystem disease with a clinical burden that is not only confined to liver-related morbidity and mortality, but that also affects several extra-hepatic organs and regulatory pathways. Thus, NAFLD is considered an important public health issue, but there is currently no effective therapy for all NAFLD patients in the general population. Studies seeking optimal therapy for NAFLD and NASH have not yet led to development of a universal protocol for treating this growing problem. Several pharmacological agents have been studied in an effort to improve insulin resistance and the proinflammatory mediators that may be responsible for NASH progression. Cardiovascular risk factors are highly prevalent among NASH patients, and the backbone of treatment regimens for these patients still comprises general lifestyle interventions, including dietary changes and increased physical activity. Vitamin E and thiazolidinedione derivatives are currently the most evidence-based therapeutic options, but only

    Full Text Available Introduction Resistant hypertension is a common and growing clinical problem characterized by the failure to attain target blood pressure levels despite adequate use of at least three antihypertensive agents. Objectives The aim of this article is to emphasize the role of novel approaches to treat resistant hypertension. Materials and methods After an excursus on the physiological role of renal nerves on kidney function, volume homeostasis and blood pressure control, this article describes the radiofrequency ablation technology to obtain kidneys denervation. Results Activation of the sympathetic nervous system plays a prominent role as a major regulator of circulatory and metabolic control. The kidneys have a particularly dense afferent sensory and efferent sympathetic innervation and are thereby strategically positioned to be origin as well as target of sympathetic activation. In this context, recent evidence suggests that a novel catheter-based approach to functionally denervate the human kidneys using radiofrequency ablation technology may provide a safe and effective treatment alternative for resistant hypertension and its adverse consequences. Conclusions Despite the availability of numerous safe and effective pharmacological therapies to treat elevated blood pressure, novel therapeutic approaches are warranted to improve the management and prognosis of patients with refractory hypertension. Several clinical trials are currently conducted and planned to further substantiate the blood pressure lowering efficacy of this novel renal denervation procedure.

    Percutaneous radiofrequency ablation (RFA) for treatment of osteoid osteoma is effective and avoids the potential complications of open surgical resection. This study evaluates the efficacy of RFA at a single tertiary-care pediatric hospital and highlights an important complication. The medical records of 21 cases of RFA in 21 children between 2004 and 2010 were reviewed retrospectively for demographic data, lesion site, access point and technique for ablation, clinical outcome and complications. Clinical follow-up was available for 17/21 children (81%) at an average of 17.0 months (range 0.5-86.1 months). No persistence or recurrence of pre-procedural pain was noted. Two children (9.5%) had a complication, including a burn to the local skin and muscle requiring local wound care, and a late subtrochanteric femur fracture treated successfully with open reduction internal fixation. RFA is a safe and effective alternative to surgical resection of the osteoid osteoma nidus. When accessing the proximal femur, the risk of late post-procedural fracture must be considered and discussed with the family. An understanding of biomechanical principles in the proximal femur might provide an effective strategy for limiting this risk. (orig.)

    Full Text Available Treatment-resistant mood and anxiety disorders require an intensive therapeutic approach, and it should balance benefits and adverse effects or other potential detrimental effects of medications. The goal of treatment is to provide consistent and lasting improvement in symptoms of depression and anxiety. Benzodiazepines are effective for anxiety symptoms, but with no sustained treatment effects. Other medication treatment options for anxiety disorders are outlined. Ketamine is usually very effective in treating major depressive disorder but without sustained benefits. Long-term use may pose a significant risk of developing tolerance and dependence. Stimulant medication augmentation for treatment-resistant depression is effective for residual symptoms of depression, but effects are usually short-lasting and it sounds more as an artificial way of improving energy, alertness and cognitive functioning. Synthetic cannabinoids and medical marijuana are increasingly prescribed for various medical conditions, but more recently also for patients with mood and anxiety disorders. All of these treatments may raise ethical dilemmas about appropri­ateness of prescribing these medications and a number of questions regarding the optimal treatment for patients with treatment-resistant depression and treatment refractory anxiety disorders.

    PurposeTo assess radiofrequency (RF) ablation efficacy, as well as the patency of transjugular intrahepatic portosystemic shunts (TIPSs), in patients with hepatocellular carcinoma (HCC).Materials and MethodsRetrospective database review of patients with pre-existing TIPS undergoing RF ablation of HCC was conducted over a 159-month period ending in November 2013. TIPS patency pre- and post-RF ablation was assessed by ultrasound, angiography, and/or contrast-enhanced CT or MRI. Patient demographics and immediate post-RF ablation outcomes and complications were also reviewed.Results19 patients with 21 lesions undergoing 25 RF ablation sessions were included. Child-Pugh class A, B, and C scores were seen in 1, 13, and 5 patients, respectively. Eleven patients (58 %) ultimately underwent liver transplantation. Immediate technical success was seen in all ablation sessions without residual tumor enhancement (100 %). No patients (0 %) suffered liver failure within 1 month of ablation. Pre-ablation TIPS patency was demonstrated in 22/25 sessions (88 %). Of 22 cases with patent TIPS prior to ablation, post-ablation patency was demonstrated in 22/22 (100 %) at immediate post-ablation imaging and in 21/22 (95 %) at last follow-up (1 patient was incidentally noted to have occlusion 31 months later). No immediate complications were observed.ConclusionAblation efficacy was similar to the cited literature values for patients without TIPS. Furthermore, TIPS patency was preserved in the majority of cases. Patients with both portal hypertension and HCC are not uncommonly encountered, and a pre-existing TIPS does not appear to be a definite contraindication for RF ablation.

    Food allergy affects approximately 5% of adults and 8% of children in developed countries, and there is currently no cure. Current pharmacologic management is limited to using intramuscular epinephrine or oral antihistamines in response to food allergen exposure. Recent trials have examined the efficacy and safety of subcutaneous, oral, sublingual, and epicutaneous immunotherapy, with varying levels of efficacy and safety demonstrated. Bacterial adjuvants, use of anti-IgE monoclonal antibodies, and Chinese herbal formulations represent exciting potential for development of future pharmacotherapeutic agents. Ultimately, immunotherapy may be a viable option for patients with food allergy, although efficacy and safety are likely to be less than ideal. PMID:26289224

  10. Registration of CT to pre-treatment MRI for planning of MR-HIFU ablation treatment of painful bone metastases

    International Nuclear Information System (INIS)

    MR-HIFU is a new non-invasive treatment modality that can be used for palliation in patients with painful bone metastases. Since treatment strategies are mainly focused on the ablation of periosteal nerves, information on the presence and geometry of cortical bone influences the treatment strategy, both in determining the acoustic power and in avoiding safety issues related to far-field heating. Although MRI is available for imaging during treatment, CT is best used for examining the cortical bone. We present a registration method for registering CT and MR images of patients with bone metastases prior to therapy. CT and MRI data were obtained from nine patients with metastatic bone lesions at varying locations. A two-step registration approach was used, performing simultaneous rigid registration of all available MR images in the first step and an affine and deformable registration with an additional bone metric in the second step. The performance was evaluated using landmark annotation by clinical observers. An average registration error of 4.5 mm was obtained, which was comparable to the slice thickness of the data. The performance of the registration algorithm was satisfactory, even with differences in MRI acquisition parameters and for various anatomical sites. The obtained CT overlay is useful for treatment planning, as it allows an assessment of the integrity of the cortical bone. CT-MR registration is therefore recommended for HIFU treatment planning of patients with bone metastases. (paper)

    Serge Evrard

    Full Text Available BACKGROUND: Combined intra-operative ablation and resection (CARe is proposed to treat extensive colorectal liver metastases (CLM. This multicenter study was conducted to evaluate overall survival (OS, local recurrence-free survival (LRFS, hepatic recurrence-free survival (HRFS and progression-free survival (PFS, to identify factors associated with survival, and to report complications. MATERIALS AND METHODS: Four centers combined retropectively their clinical experiences regarding CLM treated by CARe. CLM characteristics, pre- and post-operative chemotherapy regimens, surgical procedures, complications and survivals were analyzed. RESULTS: Of the 288 patients who received CARe, 210 (73% had synchronous and 255 (88% had bilateral CLM. Twenty-two patients (8% had extrahepatic disease. Median follow-up was 3.17 years (95%CI 2.83-4.08. Median OS was 3.33 years (95%CI 3.08-4.17 and 5-year OS was 37% (95%CI 29-45. One- and 5-year LRFS from ablated lesions were 87.9% (95%CI 83.3-91.2 and 78.0% (95%CI 71-83, respectively. Median HRFS and PFS were 14 months (95%CI 11-18 and 9 months (95%CI 8-11, respectively. One hundred patients experienced complications: 29 grade I, 68 grade II-III-IV, and three deaths. In the multivariate models adjusted for center, the occurrence of complications was confirmed as a major independent factor associated with 3-year OS (HR 1.80; P = 0.008. Five-year OS was 25.6% (95%CI 14.9-37.6 for patients with complications and 45% (95%CI 33.3-53.4 for patients without. CONCLUSIONS: Recent strategies facing advanced CLM include non-anatomic resections, portal-induced hypertrophy of the future remnant liver and aggressive medical preoperative treatments. CARe has the qualities of an approach that allows effective tumor clearance while maintaining good tolerance for the patient.

    ABSTRACT Objective: To evaluate the rate of local recurrence of extra-abdominal desmoid tumor and compare the outcomes of surgical treatment and conservative treatment. Methods: Twenty one patients (14 women and seven men), mean age 33.0±8.7 years old, with a diagnosis of desmoid tumor were evaluated. The mean follow-up period was 58.5±29.0 months. Fourteen cases involved the lower limbs, four cases involved the upper limbs, and three cases involved the trunk. The average tumor size was 12.7±7.5 cm. Of the 21 patients, 14 did not undergo previous treatment and seven patients relapsed before the initial evaluation. Surgical treatment was performed in 16 patients and conservative treatment was performed in five patients. Results: Recurrence occurred in seven patients (33%) and six of them relapsed within the first 18 months. No significant difference was observed between conservative and surgical treatment. However, a significant difference was observed among patients undergoing wide resection and who experienced improved local control. Conclusion: The recurrence rate of desmoid tumor was 33.3%. There was no difference in recurrence between conservative and surgical treatment. In surgical treatment, wide margins showed better results for recurrence control. Level of Evidence III.

    Objective To compare the therapeutic effects and safety of monopolar and bipolar radiofrequency (RF) ablation used during cardiac surgery to treat atrial fibrillation. Methods We retrospectively studied a total of 81 patients with chronic atrial fibrillation who underwent open cardiac surgery with concomitant RF ablation between January 2007 and March 2011. Fifty-eight patients received bipolar RF ablation and 23 received monopolar RF ablation, respectively. The sinus rhythm restoration rate, the procedural duration, the frequency of severe perioperative complications, and mortality were compared between the two groups. Results The sinus rhythm restoration rate did not differ significantly between the two groups after follow-up of 15.1 ± 12.6 months (P=0.199). The frequencies of severe perioperative complications and mortality were also similar in the two groups. The total procedural time using bipolar RF ablation was significantly shorter than that using monopolar ablation (19.7±4.6 minutes vs. 28.1±8.5 minutes, P Conclusions Both monopolar and bipolar RF ablation are safe and effective in treating chronic atrial fibrillation patients during open cardiac surgery, but bipolar RF ablation is more convenient in practice.

    AIM: To determine which treatment modality -hepatectomy or percutaneous ablation - is more beneficial for patients with small hepatocellular carcinoma (HCC) (≤ 4 cm) in terms of long-term outcomes.METHODS: A retrospective analysis of 149 patients with HCC ≤4 cm was conducted. Eighty-five patients underwent partial hepatectomy (anatomic in 47 and nonanatomic in 38) and 64 underwent percutaneous ablation (percutaneous ethanol injection in 37, radiofrequency ablation in 21, and microwave coagulation in 6). The median follow-up period was 69 mo.RESULTS: Hepatectomy was associated with larger tumor size (P<0.001), whereas percutaneous ablation was significantly associated with impaired hepatic functional reserve. Local recurrence was less frequent following hepatectomy (P< 0.0001). Survival was better following hepatectomy (median survival time:122 mo) than following percutaneous ablation (median survival time: 66 mo; P=0.0123). When tumor size was divided into ≤ 2 cm vs > 2 cm, the favorable effects of hepatectomy on long-term survival was seen only in patients with tumors >2 cm (P= 0.0001). The Cox proportional hazards regression model revealed that hepatectomy (P= 0.006) and tumors ≤ 2 cm (P= 0.017) were independently associated with better survival.CONCLUSION: Hepatectomy provides both better local control and better long-term survival for patients with HCC ≤4 cm compared with percutaneous ablation. Of the patients with HCC ≤ 4 cm, those with tumors > 2 cm are good candidates for hepatectomy, provided that the hepatic functional reserve of the patient permits resection.

    2008-01-01

    The expression of psoriasis is highly variable and may even differ within a single patient. This comprises not only extent of lesions, severity in terms of erythema induration, and scaling or visibility of the lesions, but particularly the responsiveness to antipsoriatic treatments in the past. Therefore, the management of psoriasis has to reconcile the variability of treatment responses, which, to some extent, may be genetically determined but also are the result of nongenetic factors, including triggering factors and adaptation (habituation) to treatments. In this article, we will provide a patient-based approach on the management of psoriasis, which reconciles the heterogeneity of psoriasis in individual patients.

    Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide and is increasingly detected at small size (liver transplantation, or percutaneous ablation have been proposed. When surgical options are precluded, image-guided tumor ablation is recommended as the most appropriate therapeutic choice in terms of tumor local control, safety, and improvement in survival. Laser ablation (LA) represents one of currently available loco-ablative techniques: light is delivered via flexible quartz fibers of diameter from 300 to 600 μm inserted into tumor lesion through either fine needles (21g Chiba needles) or large-bore catheters. The thermal destruction of tissue is achieved through conversion of absorbed light (usually infrared) into heat. A range of different imaging modalities have been used to guide percutaneous laser ablation, but ultrasound and magnetic resonance imaging are most widely employed, according to local experience and resource availability. Available clinical data suggest that LA is highly effective in terms of tumoricidal capability with an excellent safety profile; the best results in terms of long-term survival are obtained in early HCC so that LA can be proposed not only in unresectable cases but, not differently from radiofrequency ablation, also as the first-line treatment.

Renal disease (glomerulonephritis is one of the most frequent and serious manifestations of SLE. Of the various histological types of lupus glomerulonephritis, diffuse proliferative nephritis carries the worst prognosis. Combined with high-dose prednisone, mycophenolate mofetil (MMF has emerged as a first-line immunosuppressive treatment, although data regarding the efficacy of MMF on the long-term preservation of renal function are forthcoming. Cyclophosphamide is reserved for more severe forms of lupus nephritis, such as crescentic glomerulonephritis with rapidly deteriorating renal function, patients with significant renal function impairment at presentation, and refractory renal disease. Evidence for the calcineurin inhibitors in the treatment of lupus nephritis is weaker, and it concerns patients who are intolerant or recalcitrant to other agents. While further controlled trials are mandatory, B cell modulation therapies, such as rituximab, belimumab and epratuzumab are confined to refractory disease. Non-immunosuppressive measures, such as angiotensin-converting enzyme inhibitors, vigorous blood pressure control, prevention and treatment of hyperlipidemia and osteoporosis, are equally important.Keywords: lupus, nephritis, nephropathy, glomerulonephritis, treatment, therapy, women

    Full Text Available Most recommendations for treatment of anxiety in later life are based on evidence, derived from studies of younger populations. An important challenge is the high psychic and physical comorbidity of primary anxiety disorders. The aim of our study was to examine the pharmacological treatment of elderly patients in acute psychiatry setting, presenting with anxiety disorder.All subjects underwent clinical psychiatric examination and evaluation according to ICD-10 and DSM-IV criteria for an anxiety disorder and depression. The patients were examined also for a physical comorbidity.Depressive-anxious or comorbid with depression anxious patients prevailed. Primary solitary anxiety disorders were less seen. High physical comorbidity was registerd. Pharmacologic treatment consisted mostly of benzodiazepines and antidepressants. A considerable number of patients received Quetiapine in their therapeutic plans.Pharmacologic treatment in elderly patients with anxiety disorders should be precisely administered. Standard pharmacotherapy of anxiety disorders for a number of elderly patients needs to be modified. Further research is needed to determine the most appropriate safe and effective treatment model.

    Tiwari, Pallavi; Danish, Shabbar F; Jiang, Benjamin; Madabhushi, Anant

    2015-10-01

    Laser interstitial thermal therapy (LITT) has recently emerged as a new treatment modality for cancer pain management that targets the cingulum (pain center in the brain) and has shown promise over radio frequency (RF)-based ablation, due to magnetic resonance image (MRI) guidance that allows for precise ablation. Since laser ablation for pain management is currently exploratory and is only performed at a few centers worldwide, its short- and long-term effects on the cingulum are currently unknown. Traditionally, treatment effects for neurological conditions are evaluated by monitoring changes in intensities and/or volume of the ablation zone on post-treatment Gadolinium-contrast T1-w (Gd-T1) MRI. However, LITT introduces subtle localized changes corresponding to tissues response to treatment, which may not be appreciable on visual inspection of volumetric or intensity changes. Additionally, different MRI protocols [Gd-T1, T2w, gradient echo sequence (GRE), fluid-attenuated inversion recovery (FLAIR)] are known to capture complementary diagnostic information regarding the patient's response to treatment; the utility of these MRI protocols has so far not been investigated to evaluate early and localized response to LITT treatment in the context of neuropathic cancer pain. In this work, we present the first attempt at (a) examining early treatment-related changes on a per-voxel basis via quantitative comparison of computer-extracted texture descriptors across pre- and post-LITT multiparametric (MP-MRI) (Gd-T1, T2w, GRE, FLAIR), subtle microarchitectural texture changes that may not be appreciable on original MR intensities or volumetric differences, and (b) investigating the efficacy of different MRI protocols in accurately capturing immediate post-treatment changes reflected (1) within and (2) outside the ablation zone.

    Full Text Available Chronic thromboembolic pulmonary hypertension (CTEPH is a life-threatening condition in which organised thrombi obstruct the pulmonary vessels, causing increased pulmonary vascular resistance, progressive pulmonary hypertension (PH and right heart failure. The treatment of choice is pulmonary endarterectomy, which restores pulmonary haemodynamics with acceptable periprocedural mortality rates in the majority of suitable patients. However, CTEPH may be inoperable owing to surgically inaccessible thrombi or comorbid diseases that confer an unacceptably high risk. Pharmacotherapies, although not yet approved, may be useful in this situation or for treating residual or recurrent PH following surgery. Vasodilator drugs for PH are attracting growing interest as potential treatments for CTEPH because this disease has recently been labelled as a "dual" pulmonary vascular disorder: major vessel obstruction and remodelling is combined with a small vessel arteriopathy that is histologically indistinguishable from the classical pulmonary arteriopathy observed in pulmonary arterial hypertension. Of three completed randomised controlled trials in patients with CTEPH, only one was powered to detect a treatment effect. The BENEFIT trial employed the dual endothelin-receptor antagonist bosentan. Although haemodynamics improved significantly, the second component of the primary end-point, exercise capacity, was not met. More evidence is required to resolve whether vasodilator treatments are beneficial for inoperable chronic thromboembolic pulmonary hypertension.

Many treatment options have been studied. Our review aims to investigate the safety and efficacy of the multiple treatment options of CRVO. A PubMed and Cochrane literature search was performed. Well-controlled randomized clinical trials that demonstrated strong level 1 evidence-based on the rating scale developed by the British Centre for Evidence-Based Medicine were included. Seven clinical trials met inclusion criteria to be included in this review. These included studies that investigated the safety and efficacy of retinal photocoagulation (1 study, intravitreal steroid treatment (2 studies, and antivascular endothelial growth factor treatment (4 studies for the treatment of CRVO. In addition, studies evaluating surgical treatment options for CRVO were also included. Many treatment modalities have been demonstrated to be safe and efficacious in the treatment of CRVO. These treatment options offer therapeutic benefits for patients and clinically superior visual acuity and perhaps the quality of life after suffering from a CRVO.

Larger tumours (osteoblastoma, aneurysmal bone cyst and metastasis) can be addressed with radiofrequency or cryoablation. Results on the literature of spinal microwave ablation are scarce, and thus it should be used with caution. A distinct advantage of cryoablation is the ability to monitor the ice-ball by intermittent CT or MRI. The different thermal insulation, temperature and electrophysiological monitoring techniques should be applied. Cautious pre-procedural planning and intermittent intra-procedural monitoring of the ablation zone can help reduce neural complications. Tumour histology, patient clinical-functional status and life-expectancy should define the most efficient and least disabling treatment option. PMID:27329231

    Shoulder pain is a common complaint in clinical practice in Primary Care and affects 20% of the general population. The usual form of treatment is based on NSAIDs, rest, rehabilitation and, as an alternative, a local injection into the joint. There are also radiofrequency techniques on the suprascapular nerve in the cases of refractory pain to these therapies. Radiofrequency can be used in two ways: Conventional Radiofrequency, using high temperatures to the target tissue with the aim of producing a thermal neurolysis and Pulsed Radiofrequency where the temperatures are lower and produces a temporary non-destructive blockage; the latter being the most common technique in the management of shoulder pain. Although the analgesic mechanism of action of Radiofrequency is unknown, recent studies have shown that it is safe, effective and Lasting. Radiofrequency of the suprascapular nerve is a valid, effective and with few complications in the treatment of shoulder pain refractory to other therapies.

    Canavese, F; Samba, A; Rousset, M

    2016-02-01

    A fracture is defined as pathological when it arises in a bone tissue that has been modified and reshaped by a local or systemic pathological process. In children, pathological fractures can be secondary to several conditions, ranging from metabolic diseases to tumors, infections or neuromuscular pathologies. History, clinical examination and radiologic assessment are essential to making a diagnosis, to identifying the underlying cause and to planning the right treatment of a pathological fracture. Treatment must be tailored to both the fracture and the underlying cause. The objective of this work is to present the diagnostic approach and the course to follow when a child presents with a pathological fracture. The most common causes of pathological fractures, as well as their characteristics, will be described. Pathological fractures occurring in osteogenesis imperfecta and in abused children as well as stress fractures will not be discussed. PMID:26774903

    2015-09-15

    Electrical carotid baroreflex activation therapy is an emerging device-based treatment for patients with resistant hypertension. Its blood pressure lowering effect has been demonstrated in several animal and human studies, with prolonged effect over the long-term. The main mechanism of the blood pressure reduction during this therapy is by inhibition of the sympathetic outflow. Yet the question arises whether the inhibition of central sympathetic activity is sufficient to be the sole mechanism behind the sustained reduction in blood pressure. The major focus of this review is to elucidate the mechanisms of action that account for the effects of continuous carotid baroreflex activation on blood pressure in humans. Recent results of baroreflex activation therapy as a treatment for heart failure will also be discussed.

    The successful development of geothermal reservoirs to generate electric power will require the injection disposal of approximately 700,000 gal/h (2.6 x 10/sup 6/ 1/h) of heat-depleted brine for every 50,000 kW of generating capacity. To maintain injectability, the spent brine must be compatible with the receiving formation. The factors that influence this brine/formation compatibility and tests to quantify them are discussed in this report. Some form of treatment will be necessary prior to injection for most situations; the process chemistry involved to avoid and/or accelerate the formation of precipitate particles is also discussed. The treatment processes, either avoidance or controlled precipitation approaches, are described in terms of their principles and demonstrated applications in the geothermal field and, when such experience is limited, in other industrial use. Monitoring techniques for tracking particulate growth, the effect of process parameters on corrosion and well injectability are presented. Examples of brine injection, preinjection treatment, and recovery from injectivity loss are examined and related to the aspects listed above.

While the clearest guidelines for the treatment of SLE exist in the context of lupus nephritis, patients with other lupus manifestations such as neuropsychiatric, hematologic, musculoskeletal, and severe cutaneous lupus frequently require immunosuppression and/or biologic therapy. Conventional immunosuppressive agents such as mycophenolate mofetil, azathioprine, and cyclophosphamide are widely used in the management of SLE with current more rationalized treatment regimens optimizing the use of these agents while minimizing potential toxicity. The advent of biologic therapies has advanced the treatment of SLE particularly in patients with refractory disease. The CD20 monoclonal antibody rituximab and the anti-BLyS agent belimumab are now widely in use in clinical practice. Several other biologic agents are in ongoing clinical trials. While immunosuppressive and biologic agents are the foundation of inflammatory disease control in SLE, the importance of managing comorbidities such as cardiovascular risk factors, bone health, and minimizing susceptibility to infection should not be neglected.

    Purpose: This study aimed to determine the success and complication rates of radiofrequency ablation (RFA) in treatment of osteoid osteoma (OO) and duration of pain relief. Furthermore value of bone biopsy prior to the RFA was evaluated. Materials and methods: Within 61 months 39 patients (23 male, 16 female, 7-53 years, mean 18.7 years, median 17 years) suffering from osteoid osteoma were treated. Lesions were located in femur (n = 20), tibia (n = 10), spine (n = 5), humerus (n = 1), radius (n = 1), talus (n = 1) and pelvis (n = 1). In children, RFA was performed under general anaesthesia, in adults conscious sedation was preferred. In 29 of 39 (74%) lesion biopsies were obtained. Cooling of skin was performed in OOs located in bones with minor soft tissue covering (tibia, radius) and saline flushing via an additional needle was performed if the OO was adjacent to nerval structures. Primary success rate, complications, symptom-free interval, follow-up and biopsy results were evaluated. Results: Within observation period (1-61 months; median: 32 months) 38 of 39 patients were successfully treated and had no more complaints. In 3 of 38 patients relapse occurred after 1, 14 and 32 months and RFA was repeated. Two major complications (broken drill, infection) and 2 minor complications (hematoma, prolonged pain) were observed. Biopsy was able to prove diagnosis in 14 of 29 (48%) cases. Conclusions: Biopsy prior to treatment is not mandatory due to a remarkable amount of false negative findings in clinically and morphologically unambiguous cases of OO. RFA is a highly effective, efficient, minimally invasive and safe method for the treatment of OO.

    The aim of the clinical study is to evaluate Er:YAG laser ablation after two year-long clinical treatment. One hundred fifty cavities were volunteered for checking. Three restorative materials were used following manufacturer's directions. For the experiment, an Er:YAG laser drilling machine was applied. The laser delivered energy from 100 to 450 mJ, repetition rate from 1 to 4 Hz. The length of the generated pulses was 200 microseconds. During our experiments cooling of the teeth was achieved by fine water mist. The number of pulses was from 16 to 489. Caries of enamel and dentin were treated. Old insufficient fillings were also removed (not amalgam or metal alloys). The experiments followed the guidelines of the Declaration of Helsinki (1964), Tokyo (1975), Venice (1983) and Hong-Kong (1989). Clinical evaluation of fillings after 6, 12, 18 and 24 months based on ADA recommendation was used. Eight criteria were applied for the restoration control. Composite resins and glassionomers could be used as filling materials.

    Full Text Available Montserrat López-Rubio,1 Jose Antonio Garcia-Marco2 1Department of Hematology, Hospital Universitario Príncipe de Asturias, Alcalá de Henares, 2Department of Hematology, Hospital Universitario Puerta de Hierro Majadahonda, Majadahonda, Madrid, Spain Abstract: Hairy cell leukemia (HCL is a lymphoproliferative B-cell disorder characterized by pancytopenia, splenomegaly, and characteristic cytoplasmic hairy projections. Precise diagnosis is essential in order to differentiate classic forms from HCL variants, such as the HCL-variant and VH4-34 molecular variant, which are more resistant to available treatments. The current standard of care is treatment with purine analogs (PAs, such as cladribine or pentostatin, which provide a high rate of long-lasting clinical remissions. Nevertheless, ~30%–40% of the patients relapse, and moreover, some of these are difficult-to-treat refractory cases. The use of the monoclonal antibody rituximab in combination with PA appears to produce even higher responses, and it is often employed to minimize or eliminate residual disease. Currently, research in the field of HCL is focused on identifying novel therapeutic targets and potential agents that are safe and can universally cure the disease. The discovery of the BRAF mutation and progress in understanding the biology of the disease has enabled the scientific community to explore new therapeutic targets. Ongoing clinical trials are assessing various treatment strategies such as the combination of PA and anti-CD20 monoclonal antibodies, recombinant immunotoxins targeting CD22, BRAF inhibitors, and B-cell receptor signal inhibitors.

Place and Duration of Study: Outpatient Department of Armed Forces Institute of Rehabilitation Medicine, Rawalpindi from June 2012 to June 2013. Material and Methods: Ninety cases fulfilling American College of Rheumatology criteria for diagnosis of Knee Osteoarthritis and falling in Grades III of Kellgren-Lawrence Radiological Classification for Knee Osteoarthritis were included. Pre-treatment associated symptoms, complete blood count, renal and liver function tests were documented. After a baseline pain assessment on a 10-Point Visual Analogue Scale, 50 mg of Diacerein was given orally for 4 months followed by pain assessment and inquiry about adverse effects at 6th week, 3rd and 6th months. Post-treatment labs were repeated. Reduction in pain was analyzed by paired-sample t-test using SPSS version 17. Chi-Square test was used to assess the frequency of adverse effects. A p-value < 0.05 was considered significant. Results: Mean age was 61.5 ± 7.8 years. Majority 77 (85.6%) were females. Mean Visual Analogue Scale at start was 6.1 ± 0.87. Significant pain reduction measured on Visual Analogue Scale was observed at six weeks (4.6 ± 1.2) (p < 0.001), three months (2.37 ± 0.91) (p < 0.001) and six months (2.2 ± 0.85) (p < 0.001). Very few patients developed diarrhea 3.3% and nausea 4.4%. Conclusion: Diacerein is effective drug with minimal side effects for treatment of mild to moderate painful Knee Osteoarthritis. (author)

    In almost every patient, acromegaly is caused by a growth hormone secreting pituitary adenoma. Clinical features are the result of excessive growth hormone secretion and the consecutive excess in insulin-like growth factor I levels. This results in somatic overgrowth and metabolic disturbances with a higher morbidity and mortality than in the general population. With optimal disease management, mortality can be reduced to that seen in the general population. The current treatment of acromegaly is based on a combination of surgery, radiotherapy and medical therapy. This review provides an overview of the current and upcoming therapies with a focus on medical therapy.

    Urinary tract infections (UTIs) are a severe public health problem and are caused by a range of pathogens, but most commonly by Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Enterococcus faecalis and Staphylococcus saprophyticus. High recurrence rates and increasing antimicrobial resistance among uropathogens threaten to greatly increase the economic burden of these infections. In this Review, we discuss how basic science studies are elucidating the molecular details of the crosstalk that occurs at the host-pathogen interface, as well as the consequences of these interactions for the pathophysiology of UTIs. We also describe current efforts to translate this knowledge into new clinical treatments for UTIs. PMID:25853778

    Progressive supranuclear palsy (PSP) is an atypical parkinsonian condition characterized by a symmetric akinetic-rigid syndrome, early falls, supranuclear gaze palsy, and a frontotemporal behavioral syndrome. The typical phenotype is termed Richardson's syndrome, but numerous other phenotypes have been described. The pathophysiology of PSP is not fully understood, but dysfunction of the tau protein seems to play a central role. Despite exciting new knowledge on the pathophysiology of PSP, there is still no highly effective symptomatic or disease-modifying treatment. We review the evidence on pharmacotherapy and experimental therapies in PSP and provide levels of recommendation for the off-label use of commonly used drugs in this disorder. PMID:27222018

The questionnaire concerned the areas involved in psoriasis and pruritus, the pruritus characteristics, the worsening and relieving factors and treatment modalities. Itch intensity was reflected by a 10 point visual analog scale (VAS and the degree of symptoms discriminated between mild (1–3, moderate (4–7 and severe (8–10.Results: Almost 85% of psoriatic patients suffered from itching; the frequency of pruritus was daily and mean intensity by VAS scale was moderate. Presence and intensity of pruritus and body mass index (BMI were correlated. 40% of patients with pruritus were overweight (BMI > 25 < 30 and 10% obese (BMI > 30. Almost all patients appeared unsatisfied with the available treatment modalities for pruritus in psoriasis. Emollients, topical steroids and calcipotriol cream could relieve pruritus but their effect was temporary. Among the antipsoriatic therapies, phototherapy with narrow band ultraviolet B (nb-UVB was the most effective treatment in reducing pruritus. Biological therapies, mainly etanercept and efalizumab, proved useful in its control.Conclusions: The questionnaire was a useful tool to characterize itch, and the results might help us to better understand pruritus in psoriasis

    2000-01-01

    The goal of treatment for idiopathic (immune) thrombocytopenic purpura (ITP) is to prevent serious bleeding. Traditionally, corticosteroids have been used as first-line therapy followed by splenectomy. Experience with splenectomy over 60 years shows that approximately two thirds of patients achieve normal platelet counts during the initial observation, but that thrombocytopenia often recurs with longer follow-up. We know that long-term use of corticosteroids can lead to significant morbidities; there is no consensus regarding the appropriate timing or indications for splenectomy. To address the Issue of appropriate use of splenectomy, we designed a multicenter clinical trial that will randomize patients to either standard care, involving prednisone followed by splenectomy, or to a novel regimen of limited prednisone treatment followed by WinRho SDF (Nabi, Boca Raton, FL) (anti-D) therapy to maintain the platelet count in a safe range for 1 year. Anti-D can be administered easily in an outpatient setting with few side effects and can provide predictable, transient increases in platelet count. The hypothesis is that prolonged maintenance therapy with a nontoxic regimen may increase the percentage of patients who will experience a spontaneous remission from thrombocytopenia, thereby avoiding an invasive and permanent surgical procedure, splenectomy, and its potentially life-threatening sequelae.

    Full Text Available Sarah E Fitzpatrick, Laura Srivorakiat, Logan K Wink, Ernest V Pedapati, Craig A Erickson Cincinnati Children’s Hospital Medical Center, University of Cincinnati College of Medicine, Cincinnati, OH, USA Abstract: Autism spectrum disorder (ASD is a neurodevelopmental disorder characterized by persistent difficulties in social communication and social interaction, coupled with restricted, repetitive patterns of behavior or interest. Research indicates that aggression rates may be higher in individuals with ASD compared to those with other developmental disabilities. Aggression is associated with negative outcomes for children with ASD and their caregivers, including decreased quality of life, increased stress levels, and reduced availability of educational and social support. Therapeutic strategies including functional behavioral assessment, reinforcement strategies, and functional communication training may have a significant impact in reducing the frequency and intensity of aggressive behavior in individuals with ASD. Pharmacologic treatments, particularly the use of second-generation antipsychotics, may also be of some benefit in reducing aggression in individuals with ASD. With the ever-increasing rate of ASD diagnosis, development of effective therapeutic and pharmacologic methods for preventing and treating aggression are essential to improving outcomes in this disorder.

    Purpose: To determine the best treatment technique for patients with retinoblastoma requiring radiotherapy to the whole eye. Methods and Materials: Treatment plans for 3 patients with retinoblastoma were developed using 10 radiotherapy techniques including electron beams, photon beam wedge pair (WP), photon beam three-dimensional conformal radiotherapy (3D-CRT), fixed gantry intensity-modulated radiotherapy (IMRT), photon volumetric arc therapy (VMAT), fractionated stereotactic radiotherapy, and helical tomotherapy (HT). Dose-volume analyses were carried out for each technique. Results: All techniques provided similar target coverage; conformity was highest for VMAT, nine-field (9F) IMRT, and HT (conformity index [CI] = 1.3) and lowest for the WP and two electron techniques (CI = 1.8). The electron techniques had the highest planning target volume dose gradient (131% of maximum dose received [D{sub max}]), and the CRT techniques had the lowest (103% D{sub max}) gradient. The volume receiving at least 20 Gy (V{sub 20Gy}) for the ipsilateral bony orbit was lowest for the VMAT and HT techniques (56%) and highest for the CRT techniques (90%). Generally, the electron beam techniques were superior in terms of brain sparing and delivered approximately one-third of the integral dose of the photon techniques. Conclusions: Inverse planned image-guided radiotherapy delivered using HT or VMAT gives better conformity index, improved orbital bone and brain sparing, and a lower integral dose than other techniques.

    Full Text Available Sarah H Lindahl Sutter East Bay Medical Foundation, SEBMF – Diablo Division, Castro Valley, CA, USA Background: Vaginal atrophy is a chronic condition with symptoms that include vaginal dryness, pain during sex, itching, irritation, burning, and discharge, as well as various urinary problems. Up to 45% of postmenopausal women may be affected, but it often remains underreported and undertreated. This article aims to review the current recommendations for treatment of vaginal atrophy, and current data on the effectiveness and safety of local vaginal estrogen therapies. Methods: Literature regarding vaginal atrophy (2007–2012 was retrieved from PubMed and summarized, with emphasis on data related to the treatment of vaginal atrophy with local vaginal estrogen therapy. Results: Published data support the effectiveness and endometrial safety of low-dose local estrogen therapies. These results further support the general recommendation by the North American Menopause Society that a progestogen is not needed for endometrial protection in patients using low-dose local vaginal estrogen. Benefits of long-term therapy for vaginal atrophy include sustained relief of symptoms as well as physiological improvements (eg, decreased vaginal pH and increased blood flow, epithelial thickness, secretions. Conclusion: Currently available local vaginal estrogen therapies are well tolerated and effective in relieving symptoms of vaginal atrophy. Recent data support the endometrial safety of low-dose regimens for up to 1 year. Keywords: menopause, estrogen, local estrogen therapy, vaginal atrophy

    Full Text Available Marcus S Noel, Aram F Hezel James P Wilmot Cancer Center, University of Rochester, Rochester, NY, USA Abstract: Biliary tract cancer (BTC is a group of relatively rare tumors with a poor prognosis. The current standard of care consists of doublet chemotherapy (platinum plus gemcitabine; however, even with cytotoxic therapy, the median overall survival is less than 1 year. The genetic basis of BTC is now more clearly understood, allowing for the investigation of targeted therapy. Combinations of doublet chemotherapy with antiepidermal growth factor receptor agents have provided modest results in Phase II and Phase III setting, and responses with small molecule inhibitors are limited. Moving forward as we continue to characterize the genetic hallmarks of BTC, a stepwise, strategic, and cooperative approach will allow us to make progress when developing new treatments.

    Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by persistent difficulties in social communication and social interaction, coupled with restricted, repetitive patterns of behavior or interest. Research indicates that aggression rates may be higher in individuals with ASD compared to those with other developmental disabilities. Aggression is associated with negative outcomes for children with ASD and their caregivers, including decreased quality of life, increased stress levels, and reduced availability of educational and social support. Therapeutic strategies including functional behavioral assessment, reinforcement strategies, and functional communication training may have a significant impact in reducing the frequency and intensity of aggressive behavior in individuals with ASD. Pharmacologic treatments, particularly the use of second-generation antipsychotics, may also be of some benefit in reducing aggression in individuals with ASD. With the ever-increasing rate of ASD diagnosis, development of effective therapeutic and pharmacologic methods for preventing and treating aggression are essential to improving outcomes in this disorder.

    Low back pain in pregnancy is a common occurrence and is mainly caused by hormonal and biomechanical changes. Patients with pregnancy-induced low back pain (PILBP) frequently complain of moderate to severe and disabling pain often restricting their daily activities. In these cases, a “watch and wait” approach cannot be the best solution. On the basis of anamnesis and examination PILBP can be divided into three subgroups: pregnancy-related low back pain (PLBP), pelvic girdle pain (PGP) and the combination of PLBP and PGP. The three entities ask for different diagnostic workups and therapeutic modalities. There are many possible treatments for PLBP, however, only a few are based on sound evidence. Information and advice, exercise and training programs, acupuncture, stabilizing belts and analgesic medication can have a positive impact on pain and disability. PGP und PLBP respond well to chiropractic interventions.

    2016-01-01

    Uterine endometrial stromal sarcomas including true low-grade endometrial stromal sarcoma (LG-ESS) and high-grade (HG-ESS) or undifferentiated endometrial sarcoma (UES) constitute a group of rare, aggressive malignancies. Most LG-ESSs express steroid receptors. Surgery is the principal primary therapy for endometrial stromal sarcomas and should be considered in all cases. These malignancies are relatively radio- and chemoresistant. Chemotherapy is used in recurrent and advanced HG-ESS and UES. Currently, the combination of gemcitabine and docetaxel is considered the most effective regimen, but at the expense of substantial toxicity. In steroid receptor positive advanced LG-ESS hormonal therapy, mainly with progestins, allows in some patients for a long-term survival. Aromatase inhibitors seem to be equally effective as first- and subsequent-line of treatment, and are well tolerated. The role of molecular-targeted therapies in endometrial stromal sarcomas remains to be established. PMID:27629136

    2015-01-01

    Cerebral malaria, a severe form of the disease, is one of the most severe complications of infection with Plasmodium parasites and a leading cause of malaria mortality. Currently available antimalarial therapy has proven insufficient to prevent neurological complications and death in all cases of cerebral malaria. Souza and colleagues observed that transplantation of bone marrow-derived mesenchymal stromal cells (BM-MSCs) increased survival, reduced parasitemia, decreased malaria pigment accumulation in the spleen, liver and kidney, elevated Kupffer cell count in liver, alleviated renal injury and lung inflammation, and improved lung mechanics in an experimental mouse model of cerebral malaria. Although plenty of challenges lie ahead, their findings show the promise of BM-MSC therapy for the treatment of cerebral malaria. PMID:26253514

    Background. Stereotactic radiation therapy is an evolving modality to treat otherwise unresectable liver metastases. In this analysis, two local therapies: 1) single session robotic radiosurgery (RRS) and 2) percutaneous radiofrequency ablation (RFA) were compared in a total of 60 heavily pretreated colorectal cancer patients. Methods. Thirty patients with a total of 35 colorectal liver metastases not qualifying for surgery that were treated in curative intent with RRS were prospectively followed. To compare efficacy of both treatment modalities, patients treated with RFA during the same period of time were matched according to number and size of the treated lesions. Local tumor control, local disease free survival (DFS), and freedom from distant recurrence (FFDR) were analyzed for effi cacy. Treatment-related side effects were recorded for comparison. Results. The median diameter of the treated lesions was 33 mm (7-53 mm). Baseline characteristics did not differ significantly between the groups. One- and two-year local control rates showed no signifi cant difference but favored RRS (85% vs. 65% and 80% vs. 61%, respectively). A signifi cantly longer local DFS of patients treated with RRS compared to RFA (34.4 months vs. 6.0 months; p 0.001) was found. Both, median FFDR (11.4 months for RRS vs. 7.1 months for RFA p=0.25) and the recurrence rate (67% for RRS and 63% for RFA, p>0.99) were comparable. Conclusion. Single session RRS is a safe and effective method to treat colorectal liver metastases. In this analysis, a trend towards longer DFS was seen in patients treated with RRS when compared to RFA.

    Stem cells are of global excitement for various diseases including heart diseases. It is worth to understand the mechanism or role of stem cells in the treatment of heart failure. Bone marrow derived stem cells are commonly practiced with an aim to improve the function of the heart. The majority of studies have been conducted with acute myocardial infarction and a few has been investigated with the use of stem cells for treating chronic or dilated cardiomyopathy. Heterogeneity in the treated group using stem cells has greatly emerged. Ever increasing demand for any alternative made is of at most priority for cardiomyopathy. Stem cells are of top priority with the current impact that has generated among physicians. However,meticulous selection of proper source is required since redundancy is clearly evident with the present survey. This review focuses on the methods adopted using stem cells for heart diseases and outcomes that are generated so far with an idea to determine the best therapeutic possibility in order to fulfill the present demand.

    Alcoholic hepatitis(AH) is an acute hepatic manifesta-tion occurring from heavy alcohol ingestion. Alcoholic steatohepatitis(ASH) is histologically characterized by steatosis, inflammation, and fibrosis in the liver. Despite the wide range of severity at presentation, those with severe ASH(Maddrey’s discriminant function ≥ 32) typically present with fever, jaundice, and abdominal tenderness. Alcohol abstinence is the cornerstone of therapy for AH and, in the milder forms, is sufficient for clinical recovery. Severe ASH may progress to multi-or-gan failure including acute kidney injury and infection. Thus, infection and renal failure have a major impact on survival and should be closely monitored in patients with severe ASH. Patients with severe ASH have a re-ported short-term mortality of up to 40%-50%. Severe ASH at risk of early death should be identified by one of the available prognostic scoring systems before consid-ering specific therapies. Corticosteroids are the main-stay of treatment for severe ASH. When corticosteroids are contraindicated, pentoxifylline may be alternatively used. Responsiveness to steroids should be assessed at day 7 and stopping rules based on Lille score should come into action. Strategically, future studies for pa-tients with severe ASH should focus on suppressing inflammation based on cytokine profiles, balancing he-patocellular death and regeneration, limiting activation of the innate immune response, and maintaining gut mucosal integrity.

    Neoadjuvant systemic therapy (NST) has become a well-established treatment method for patients with breast cancer, not only for those with large tumors, but also for patients with early high-risk cancers. In earlier times, the clinical advantage of NST was seen in improvement of tumor shrinkage for better operability, conversion of mastectomy candidates to breast conservation, and optimization of cosmetic results. Over the decades, therapy regimens were optimized, resulting in significantly higher response rates. Rates for breast conservation and for conversion from mastectomy to breast conservation, especially for patients with advanced breast cancers, rose significantly for patients undergoing NST. A multidisciplinary approach with close and accurate diagnostic assessment of the breast, axillary tumor, or both during NST and individual-response-guided surgery is mandatory. To reduce unnecessary surgery and prevent mastectomies, more conclusive prediction models and minimally invasive methods for selection of patients with pathologic complete remission after NST are needed. Furthermore, prospective studies demonstrate that sentinel node biopsy for patients with initial clinically node-positive axillary nodes converting to clinically node-negative axillary nodes is oncologically safe and offers less morbidity, avoiding complete axillary node dissection. Initial concerns regarding surgical complications and morbidity due to potential immune frailty of patients with NST were not observed. PMID:27364505

    Water softening sludge (>4000 stored low level contaminated drums; 600 drums per year) generated by the ORNL Process Waste Treatment Plant must be treated, stabilized, and placed in safe storage/disposal. The sludge is primarily CaCO{sub 3} and is contaminated by low levels of {sup 90}Sr and {sup 137}Cs. In this study, microwave sintering and calcination were evaluated for treating the sludge. The microwave melting experiments showed promise: volume reductions were significant (3-5X), and the waste form was durable with glass additives (LiOH, fly ash). A commercial vendor using surrogate has demonstrated a melt mineralization process that yields a dense monolithic waste form with a volume reduction factor (VR) of 7.7. Calcination of the sludge at 850-900 C yielded a VR of 2.5. Compaction at 4500 psi increased the VR to 4.2, but the compressed form is not dimensionally stable. Addition of paraffin helped consolidate fines and yielded a VR of 3.5. In conclusion, microwave melting or another form of vitrification is likely to be the best method; however for immediate implementation, the calculation/compaction/waxing process is viable.

    Full Text Available Recent evidence indicates that, alongside oxidative stress, dysregulation of the cell cycle in neurons susceptible to degeneration in Alzheimer disease may play a crucial role in the initiation of the disease. As such, the role of reproductive hormones, which are closely associated with the cell cycle both during development and after birth, may be of key import. While estrogen has been the primary focus, the protective effects of hormone replacement therapy on cognition and dementia only during a “crucial period” led us to expand the study of hormonal influences to other members of the hypothalamic pituitary axis. Specifically, in this review, we focus on luteinizing hormone, which is not only increased in the sera of patients with Alzheimer disease but, like estrogen, is modulated by hormone replacement therapy and also influences cognitive behavior and pathogenic processing in animal models of the disease. Targeting gonadotropins may be a useful treatment strategy for disease targeting multiple pleiotropic downstream consequences.

    Insomnia is a prevalent disorder with deleterious effects such as decreased quality of life, and a predisposition to a number of psychiatric disorders. Fortunately, numerous approved hypnotic treatments are available. This report reviews the state of the art of pharmacotherapy with a reference to cognitive behavioral therapy for insomnia (CBT-I) as well. It provides the clinician with a guide to all the Food and Drug Administration (FDA) approved hypnotics (benzodiazepines, nonbenzodiazepines, ramelteon, low dose sinequan, and suvorexant) including potential side effects. Frequently, chronic insomnia lasts longer than 2 years. Cognizant of this and as a result of longer-term studies, the FDA has approved all hypnotics since 2005 without restricting the duration of use. Our manuscript also reviews off-label hypnotics (sedating antidepressants, atypical antipsychotics, anticonvulsants and antihistamines) which in reality, are more often prescribed than approved hypnotics. The choice of which hypnotic to choose is discussed partially being based on which segment of sleep is disturbed and whether co-morbid illnesses exist. Lastly, we discuss recent label changes required by the FDA inserting a warning about "sleep-related complex behaviors", e.g., sleep-driving for all hypnotics. In addition, we discuss FDA mandated dose reductions for most zolpidem preparations in women due to high zolpidem levels in the morning hours potentially causing daytime carry-over effects.

    Mitochondrial myopathies are caused by genetic mutations that directly influence the functioning of the electron transport chain (ETC). It is estimated that 1 of 8,000 people have pathology inducing mutations affecting mitochondrial function. Diagnosis often requires a multifaceted approach with measurements of serum lactate and pyruvate, urine organic acids, magnetic resonance spectroscopy (MRS), muscle histology and ultrastructure, enzymology, genetic analysis, and exercise testing. The ubiquitous distribution of the mitochondria in the human body explains the multiple organ involvement. Exercise intolerance is a common but often an overlooked hallmark of mitochondrial myopathies. The muscle consequences of ETC dysfunction include increased reliance on anaerobic metabolism (lactate generation, phosphocreatine degradation), enhanced free radical production, reduced oxygen extraction and electron flux through ETC, and mitochondrial proliferation or biogenesis (see article by Hood in current issue). Treatments have included antioxidants (vitamin E, alpha lipoic acid), electron donors and acceptors (coenzyme Q10, riboflavin), alternative energy sources (creatine monohydrate), lactate reduction strategies (dichloroacetate) and exercise training. Exercise is a particularly important modality in diagnosis as well as therapy (see article by Taivassalo in current issue). Increased awareness of these disorders by exercise physiologists and sports medicine practitioners should lead to more accurate and more rapid diagnosis and the opportunity for therapy and genetic counseling.

It has been calculated that about one-third of adult women have experienced an episode of symptomatic cystitis at least once. It is also common for these episodes to recur. If predisposing factors are not identified and removed, UTI can lead to more serious consequences, in particular kidney damage and renal failure. The aim of this review was to analyze the factors more commonly correlated with UTI in women, and to see what possible solutions are currently used in general practice and specialized areas, as well as those still under investigation. A good understanding of the possible pathogenic factors contributing to the development of UTI and its recurrence will help the general practitioner to interview the patient, search for causes that would otherwise remain undiscovered, and to identify the correct therapeutic strategy.Keywords: urinary tract infection, women, etiology, diagnosis, treatment

    Therapy based on androgenic deprivation is one of the standard treatments that many prostate cancer patients receive.Moreover,its use is increasing owing to a clear expansion of the indications for this therapy in patients with localized prostate cancer.Despite classically being considered to be well tolerated,androgenic deprivation has adverse effects.Of these,the loss of mineral bone mass is particularly notable and can lead to osteoporosis,as well as an increased risk of bone fracture.Some fractures,such as hip fractures,may have serious consequences.Useful procedures such as bone densitometry can aid in the diagnosis of these conditions.Once diagnosed,decreases in mineral bone mass can be managed by dietary recommendations,general changes in lifestyle or medication.We review the most important randomized controlled trials evaluating different drugs (bisphosphonates,denosumab and toremifene) in the prevention of bone loss and in the reduction in fracture risk in prostate cancer patients treated with androgen-deprivation therapy.Following the applicable recommendations,urologists must carefully monitor the bone health of prostate cancer patients subjected to androgenic deprivation to obtain an early diagnosis and apply the appropriate general and/or therapeutic measures if necessary.

    Full Text Available Hepatitis C currently infects more than 170 million people around the world, leading to significant morbidity and mortality. The current standard of care for HCV infection, including one of the two protease inhibitors, telaprevir or boceprevir, for 12-32 weeks, along with pegylated interferon alfa-2a (PEG-IFN-α and ribavirin for up to 48 weeks, is unsatisfactory in many cases, either because of lack of efficacy or because of treatment-related adverse effects. There is an urgent need of new drugs with improved efficacy as well as a safety profile. Sofosbuvir, a recently approved nucleotide analog, is a highly potent inhibitor of the NS5B polymerase in the Hepatitis C virus (HCV, and has shown high efficacy in combination with several other drugs, with and without PEG-INF, against HCV. It offers many advantages due to its high potency, low side effects, oral administration, and high barrier to resistance. The efficacy and safety were demonstrated in many large and well-designed phase 2 and phase 3 clinical trials like NEUTRINO, PROTON, ELECTRON, ATOMIC, COSMOS, FUSION, FISSION, NUCLEAR, POSITRON, and the like. It is generally well-tolerated. Adverse events that occurred include: Headache, insomnia, fatigue, nausea, dizziness, pruritis, upper respiratory tract infections, rash, back pain, grade 1 anemia, and grade 4 lymphopenia; however, the exact safety profile can only be judged when this drug is actually used on a large scale.

    2015-01-01

    Introduction:Transcatheter arterial chemoembolization (TACE) plus thermal ablation has been widely used recently in the treatment of hepatocellular carcinoma (HCC). In this study, we aimed to compare results of the combination of TACE and percutaneous thermal ablation with those of hepatectomy in patients with HCC. Methods:The clinical data of 137 HCC patients who sequentially received TACE and computed tomography (CT)-guided percutaneous thermal ablation as an initial curative treatment (combination group) and 148 matched HCC patients who received hepatectomy (surgery group) between 2004 and 2011 were collected and analyzed. After TACE, multiphase contrast-enhanced CT was performed to identify the total number of tumors as well as lipiodol deposition in the liver. Survival was calculated by using the Kaplan-Meier method and compared by using the log-rank test. The prognostic factors were assessed with multivariate Cox proportional hazards regression analysis. Results:Of all 285 patients, 225 (79.0%) had cancerous lesions≤5 cm in diameter. In preoperative contrast-enhanced CT or magnetic resonance imaging, the number of tumors was 1–4 for each patient. The 1-, 3-, and 5-year overal survival rates were 95, 74%, and 67%in the combination group and 88, 66, and 47%in the surgery group, respectively (P=0.004);the corresponding recurrence-free survival rates for the two groups were 92, 69, and 61%and 75, 58, and 44%, respectively (P=0.001). In the multivariate analysis, treatment al ocation was an independent prognostic factor for survival. Only 60 patients in the combination group had sufficient imaging data, and 135 new lesions with lipiodol deposition were diagnosed as malignancies in 22 of 60 patients, whereas 20 new lesions were found in 11 of 148 patients in the surgery group. Conclusion:The combination of TACE and CT-guided percutaneous thermal ablation for HCC improves survival of HCC patients compared with hepatectomy.

    In benign prostatic hyperplasia (BPH) there will be a sudden impact on overall quality of life of patient. This disease occurs normally at the age of 40 or above and also is associated with sexual dysfunction. Thus, there is a need of update on current medications of this disease. The presented review provides information on medications available for BPH. Phytotherapies with some improvements in BPH are also included. Relevant articles were identified through a search of the English-language literature indexed on MEDLINE, PUBMED, Sciencedirect and the proceedings of scientific meetings. The search terms were BPH, medications for BPH, drugs for BPH, combination therapies for BPH, Phytotherapies for BPH, Ayurveda and BPH, BPH treatments in Ayurveda. Medications including watchful waitings, Alpha one adrenoreceptor blockers, 5-alpha reductase inhibitors, combination therapies including tamsulosin-dutasteride, doxazosin-finasteride, terazosin-finasteride, tolterodine-tamsulosin and rofecoxib-finasteride were found. Herbal remedies such as Cernilton, Saxifraga stolonifera, Zi-Shen Pill (ZSP), Orbignya speciosa, Phellodendron amurense, Ganoderma lucidum, Serenoa Repens, pumpkin extract and Lepidium meyenii (Red Maca) have some improvements on BPH are included. Other than these discussions on Ayurvedic medications, TURP and minimally invasive therapies (MITs) are also included. Recent advancements in terms of newly synthesized molecules are also discussed. Specific alpha one adrenoreceptor blockers such as tamsulosin and alfuzosin will remain preferred choice of urologists for symptom relief. Medications with combination therapies are still needs more investigation to establish as preference in initial stage for fast symptom relief reduced prostate growth and obviously reduce need for BPH-related surgery. Due to lack of proper evidence Phytotherapies are not gaining much advantage. MITs and TURP are expensive and are rarely supported by healthcare systems. PMID:22923974

    Laser interstitial thermal therapy (LITT) has recently emerged as a new treatment modality for cancer pain management that targets the cingulum (pain center in the brain), and has shown promise over radio-frequency (RF) based ablation which is reported to provide temporary relief. One of the major advantages enjoyed by LITT is its compatibility with magnetic resonance imaging (MRI), allowing for high resolution in vivo imaging to be used in LITT procedures. Since laser ablation for pain management is currently exploratory and is only performed at a few centers worldwide, its short-, and long-term effects on the cingulum are currently unknown. Traditionally treatment effects are evaluated by monitoring changes in volume of the ablation zone post-treatment. However, this is sub-optimal since it involves evaluating a single global parameter (volume) to detect changes pre-, and post-MRI. Additionally, the qualitative observations of LITT-related changes on multi-parametric MRI (MPMRI) do not specifically address differentiation between the appearance of treatment related changes (edema, necrosis) from recurrence of the disease (pain recurrence). In this work, we explore the utility of computer extracted texture descriptors on MP-MRI to capture early treatment related changes on a per-voxel basis by extracting quantitative relationships that may allow for an in-depth understanding of tissue response to LITT on MRI, subtle changes that may not be appreciable on original MR intensities. The second objective of this work is to investigate the efficacy of different MRI protocols in accurately capturing treatment related changes within and outside the ablation zone post-LITT. A retrospective cohort of studies comprising pre- and 24-hour post-LITT 3 Tesla T1-weighted (T1w), T2w, T2-GRE, and T2-FLAIR acquisitions was considered. Our scheme involved (1) inter-protocol as well as inter-acquisition affine registration of pre- and post-LITT MRI, (2) quantitation of MRI parameters

    Purpose: To evaluate the energy efficiency of differently sized volumetric ablations in MR-guided high-intensity focused ultrasound (MR-HIFU) treatment of uterine fibroids. Materials and methods: This study was approved by the institutional review board and informed consent was obtained from all participants. Ten symptomatic uterine fibroids (mean diameter 8.9 cm) in 10 women (mean age 42.2) were treated by volumetric MR-HIFU ablation under binary feedback control. The energy efficiency (mm{sup 3}/J) of each sonication was calculated as the volume of lethal thermal dose (240 equivalent minutes at 43 Degree-Sign C) per unit acoustic energy applied. Operator-controllable parameters and signal intensity ratio of uterine fibroid to skeletal muscle on T2-weighted MR images were tested with univariate and multivariate analyses to discern which parameters significantly correlated with the ablation energy efficiency. Results: We analyzed a total of 236 sonications. The energy efficiency of the ablations was 0.42 {+-} 0.25 mm{sup 3}/J (range 0.004-1.18) with energy efficiency improving with the treatment cell size (4 mm, 0.06 {+-} 0.06 mm{sup 3}/J; 8 mm, 0.29 {+-} 0.12 mm{sup 3}/J; 12 mm, 0.58 {+-} 0.18 mm{sup 3}/J; 16 mm, 0.91 {+-} 0.17 mm{sup 3}/J). Treatment cell size (r = 0.814, p < 0.001), distance of ultrasound propagation (r = -0.151, p = 0.020), sonication frequency (1.2 or 1.45 MHz; p < 0.001), and signal intensity ratio (r = -0.205, p = 0.002) proved to be significant by univariate analysis, while multivariate analysis revealed treatment cell size (B = 0.075, p < 0.001), US propagation distance (B = -6.928, p < 0.001), and signal intensity ratio (B = -0.024, p = 0.001) to be independently significant. Conclusion: Energy efficiency in volumetric MR-HIFU ablation of uterine fibroids improves with increased treatment cell size, independent of other significant contributors such as distance of ultrasound propagation or signal intensity of the tumor on T2-weighted MR

    This is a case of a 78-year-old male patient with multiple angiomyolipomas of a solitary right kidney. The largest of these tumors (maximum diameter: 13.4 cm) caused significant extrinsic compression of the inferior vena cava complicated by thrombosis of this vessel. Treatment of thrombosis with anticoagulants had been ineffective and the patient had experienced a bleeding episode from the largest right renal angiomyolipoma, which had been treated by transarterial embolization in another institution, 4 months prior to our intervention. Our approach included superselective transarterial embolization of the dominant, right kidney angiomyolipoma with hydrogel microspheres, which was combined, 20 days later, with ultrasonographically guided radiofrequency ablation. Both interventions were uneventful. Computed tomography 2 months after ablation showed a 53% reduction in tumor volume, reduced space-occupying effect on inferior vena cava, and resolution of caval thrombus. Nine months after intervention the patient has had no recurrence of thrombosis or hemorrhage and no tumor regrowth has been observed. The combination of superselective transarterial embolization and radiofrequency ablation seems to be a feasible, safe, and efficient treatment of large renal angiomyolipomas. PMID:27293932

    High-grade dysplasia (HGD) in Barrett's esophagus (BE) is the critical step before invasive esophageal adeno-carcinoma. Although its natural history remains unclear, an aggressive therapeutic approach is usually indicated. Esophagectomy represents the only treatment able to reliably eradicate the neoplastic epithelium. In healthy patients with reasonable life expectancy, vagal-sparing esophagectomy, with associated low mortality and low early and late postoperative morbidity, is considered the treatment of choice for BE with HGD. Patients unfit for surgery should be managed in a less aggressive manner, using endoscopic ablation or endoscopic mu-cosal resection of the entire BE segment, followed by lifelong surveillance. Patients eligible for surgery who present with a long BE segment, multifocal dysplastic lesions, severe reflux symptoms, a large fixed hiatal hernia or dysphagia comprise a challenging group with regard to the appropriate treatment, either surgical or endoscopic.

    @@ Radiofrequency (RF) ablation of the critical isthmus between the tricuspid annulus and the inferior vena cava is commonly used to treat typical atrial flutter (AFL).1 This has become the first line therapy in Europe and in the US due to its high success rate and significant improvement in quality of life compared with conventional medical therapy.2 Sizeable lesions are required to achieve persistent bidirectional conduction block (BCB), which is the best endpoint to ensurelong-term success.3,4 Cooling the ablation electrode by irrigation has been shown to prevent both overheating of the electrode-tissue interface and impedance rise during RF delivery, allowing greater power delivery and larger,deeper lesion.5 Recent studies showed that pain-free cryoablation was comparable to RF ablation regardingthe short and long-term clinical success rate and safety.6However, no studies have shown that cryoablation is superior to the irrigation RF ablation. In this study, we compared the efficacy and safety of cryoablation with the irrigation radiofrequency ablation technologies for typical AFL.

  3. Careful treatment planning enables safe ablation of liver tumors adjacent to major blood vessels by percutaneous irreversible electroporation (IRE)

    International Nuclear Information System (INIS)

    Irreversible electroporation (IRE) is a tissue ablation method, which relies on the phenomenon of electroporation. When cells are exposed to a sufficiently electric field, the plasma membrane is disrupted and cells undergo an apoptotic or necrotic cell death. Although heating effects are known IRE is considered as non-thermal ablation technique and is currently applied to treat tumors in locations where thermal ablation techniques are contraindicated. The manufacturer of the only commercially available pulse generator for IRE recommends a voltage-to-distance ratio of 1500 to 1700 V/cm for treating tumors in the liver. However, major blood vessels can influence the electric field distribution. We present a method for treatment planning of IRE which takes the influence of blood vessels on the electric field into account; this is illustrated on a treatment of 48-year-old patient with a metastasis near the remaining hepatic vein after a right side hemi-hepatectomy. Output of the numerical treatment planning method shows that a 19.9 cm3 irreversible electroporation lesion was generated and the whole tumor was covered with at least 900 V/cm. This compares well with the volume of the hypodense lesion seen in contrast enhanced CT images taken after the IRE treatment. A significant temperature raise occurs near the electrodes. However, the hepatic vein remains open after the treatment without evidence of tumor recurrence after 6 months. Treatment planning using accurate computer models was recognized as important for electrochemotherapy and irreversible electroporation. An important finding of this study was, that the surface of the electrodes heat up significantly. Therefore the clinical user should generally avoid placing the electrodes less than 4 mm away from risk structures when following recommendations of the manufacturer

    This retrospective study aimed at evaluating the long-term outcomes and prognostic factors of microwave ablation (MWA) as a first-line treatment for hepatocellular carcinoma (HCC). 221 consecutive patients receiving MWA in our center between October 11, 2010 and December 31, 2013 were enrolled. Technique effectiveness was evaluated one month post-ablation. Initial complete ablation (CA1(st)) was gained in 201 (90.95%) patients, secondary CA (CA2(nd)) in 8 (3.62%) patients and the remaining 12 (5.43%) patients suffered from incomplete ablation (IA2(nd)) after two sessions of MWA. Patients with tumor size >5 cm were less likely to gain CA1(st). Procedure-related complications were recorded and no procedure-related death occurred. 22 (10.4%) complications occurred with 8 (3.8%) being major ones. Tumor characteristics (size, number, location) do not significantly influence complication rates. After a median follow-up of 41.0 (ranging 25.0-63.5) months, the median RFS and OS was 14.0 months (95% CI: 9.254-18.746) and 41.0 months (95% CI: 33.741-48.259) respectively. Multivariate analysis identified two significant prognosticators (levels of alpha fetal protein [AFP] and gamma-glutamyl transpeptidase [GGT]) of RFS and five significant prognosticators (tumor number, tumor size, AFP, GGT and recurrence type) of OS. In conclusion, MWA provides high technique effectiveness rate and is well tolerated in patients with HCC as a first-line treatment. PMID:27620527

    The basic properties of lasers and pulsed light sources limit their ability to deliver high energy to the dermis and subcutaneous tissues without excessive damage to the epidermis. Radiofrequency was shown to penetrate deeper than optical light sources independent of skin color. The early RF-based devices used single source bipolar RF, which is safe but limited in use due to the superficial flow of energy between the two bipolar electrodes. Another type of single source RF employs a single electrode (monopolar) in which the RF energy flows from one electrode on the surface of the skin through the entire body to a plate under the body. Although more effective than bipolar, this devices require intense active cooling of the skin and may be associated with considerable pain and other systemic and local safety concerns. Latest generation of RF technology developed by EndyMed Medical Ltd. (Caesarea, Israel) utilizes simultaneously six or more phase controlled RF generators (3DEEP technology). The multiple electrical fields created by the multiple sources "repel" or "attract" each other, leading to the precise 3 dimensional delivery of RF energy to the dermal and sub-dermal targets minimizing the energy flow through the epidermis without the need for active cooling. Confocal microscopy of the skin has shown that 6 treatment sessions of Multisource RF technology improve skin structure features. The skin after treatment had longer and narrower dermal papilla and denser and finer collagen fiber typical to younger skin as compared to pre treatment skin. Ultrasound of the skin showed after 6 treatment sessions reduction of 10 percent in the thickness of the subcutaneous fat layer. Non ablative facial clinical studies showed a significant reduction of wrinkles after treatment further reduced at 3 months follow-up. Body treatment studies showed a circumference reduction of 2.9 cm immediately after 6 treatments, and 2 cm at 12 months after the end of treatment, proving long term

  9. A structured Approach for selecting the best option for active liquid waste treatment technology

    International Nuclear Information System (INIS)

    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)

    The purpose of this study was to systematically evaluate dose distributions computed with 5 different dose algorithms for patients with lung cancers treated using stereotactic ablative body radiotherapy (SABR). Treatment plans for 133 lung cancer patients, initially computed with a 1D-pencil beam (equivalent-path-length, EPL-1D) algorithm, were recalculated with 4 other algorithms commissioned for treatment planning, including 3-D pencil-beam (EPL-3D), anisotropic analytical algorithm (AAA), collapsed cone convolution superposition (CCC), and Monte Carlo (MC). The plan prescription dose was 48 Gy in 4 fractions normalized to the 95% isodose line. Tumors were classified according to location: peripheral tumors surrounded by lung (lung-island, N=39), peripheral tumors attached to the rib-cage or chest wall (lung-wall, N=44), and centrally-located tumors (lung-central, N=50). Relative to the EPL-1D algorithm, PTV D95 and mean dose values computed with the other 4 algorithms were lowest for "lung-island" tumors with smallest field sizes (3-5 cm). On the other hand, the smallest differences were noted for lung-central tumors treated with largest field widths (7-10 cm). Amongst all locations, dose distribution differences were most strongly correlated with tumor size for lung-island tumors. For most cases, convolution/superposition and MC algorithms were in good agreement. Mean lung dose (MLD) values computed with the EPL-1D algorithm were highly correlated with that of the other algorithms (correlation coefficient =0.99). The MLD values were found to be ~10% lower for small lung-island tumors with the model-based (conv/superposition and MC) vs. the correction-based (pencil-beam) algorithms with the model-based algorithms predicting greater low dose spread within the lungs. This study suggests that pencil beam algorithms should be avoided for lung SABR planning. For the most challenging cases, small tumors surrounded entirely by lung tissue (lung-island type), a Monte

    Lennox-Gastaut syndrome (LGS) is a severe epileptic encephalopathy that appears in childhood. LGS is characterized by a slow spike-wave pattern on electroencephalogram (EEG), cognitive impairment, and multiple seizure types. This mixture of seizure types, along with the need to use more than one type of medication, makes LGS one of the most complicated epilepsies to treat successfully. Recent developments in approved therapies for the treatment of LGS offer physicians more options, but also make developing a treatment strategy that minimizes adverse events more challenging. There are currently 5 treatment options for LGS: felbamate, lamotrigine, topiramate, rufinamide, and clobazam, and several others that are used off-label, each of which has benefits and limitations. There are several factors that must be considered when determining which medication to use when treating patients with LGS, including efficacy, which is assessed by seizure frequency, tolerability, and the anticipated duration of treatment. In this article, data supporting current treatment options are discussed, and important considerations about the treatment of LGS are reviewed.

    Purpose. Previous clinical studies have shown the safety and efficacy of this novel radiofrequency ablation catheter when used for endoscopic palliative procedures. We report a retrospective study with the results of first in man percutaneous intraductal radiofrequency ablation in patients with malignant biliary obstruction. Methods. Thirty-nine patients with inoperable malignant biliary obstruction were included. These patients underwent intraductal biliary radiofrequency ablation of their malignant biliary strictures following external biliary decompression with an internal-external biliary drainage. Following ablation, they had a metal stent inserted. Results. Following this intervention, there were no 30-day mortality, hemorrhage, bile duct perforation, bile leak, or pancreatitis. Of the 39 patients, 28 are alive and 10 patients are dead with a median survival of 89.5 (range 14-260) days and median stent patency of 84.5 (range 14-260) days. One patient was lost to follow-up. All but one patient had their stent patent at the time of last follow-up or death. One patient with stent blockage at 42 days postprocedure underwent percutaneous transhepatic drain insertion and restenting. Among the patients who are alive (n = 28) the median stent patency was 92 (range 14-260) days, whereas the patients who died (n = 10) had a median stent patency of 62.5 (range 38-210) days. Conclusions. In this group of patients, it appears that this new approach is feasible and safe. Efficacy remains to be proven in future, randomized, prospective studies.

  15. Atrio-esophageal fistula after AF ablation: Pathophysiology,Prevention & Treatment

    2013-10-01

    Full Text Available Atrioesophageal fistula is a very rare but often fatal late complication of atrial fibrillation ablation procedures resulting from thermal injury to the esophagus and surrounding structures. Causes of death include cerebral air embolism, massive gastrointestinal bleeding, and septic shock. Because of its unusual rate of occurrence, there has not been an uniform approach to either the diagnosis or corrective therapy. This low incidence poses a challenge in strictly determining effective preventive measures during and immediately following posterior wall left atrial ablation. Currently, strategies proposed to prevent esophageal injury include reduced power titration while ablating the posterior left atrial wall, limiting RF delivery time, avoiding overlapping ablation lines as well as monitoring intraluminal esophageal temperature, using conscious sedation rather than general anesthesia for better pain perception, monitoring intraprocedural esophageal position in relation to the posterior left atrium and extensive patient education regarding signs and symptoms of esophageal injury. Early diagnosis is essential to enable therapeutic preventive strategies to minimize the excessive morbidity and mortality associated with this condition. Unfortunately, despite application of such preventive measures, cases of atrial-esophageal fistula have still been reported. If esophageal injury with fistula formation is clinically suspected, a prompt diagnosis and an immediate aggressive intervention including stenting and/or surgical intervention is required for the patient’survival.

    Hemicrania continua (HC) is an uncommon primary headache disorder in which the diagnosis centers on unilaterality and its absolute responsiveness to indomethacin. We describe 3 patients with a long standing history of headache diagnosed as hemicrania continua. There was profound response to indomethacin which was limited by side effects. In one patient the therapy with indomethacin was limited secondary to co-morbidities. Initial diagnostic blockade provided significant relief of symptoms based on which radio-frequency ablation of the supraorbital nerve was performed with substantial improvement in symptoms. Traditionally, hemicrania continua has been managed exclusively with oral analgesics and is defined by its singular response to indomethacin. Radio-frequency ablation (RFA) has been reported in the literature for multiple indications. This case series is unique in that it describes 3 patients diagnosed with hemicrania continua with pain referred in the supraorbital nerve distribution, who underwent radiofrequency ablation of the supraorbital nerve with resultant resolution of headaches. Traditionally, hemicrania continua has been managed exclusively with oral analgesics and is defined by its singular response to indomethacin. This report is unique in that it describes three patients diagnosed with hemicrania continua with pain referred in the supraorbital nerve distribution who underwent radiofrequency ablation of the supraorbital nerve with resultant resolution of headaches. After the RFA medical management was minimal to none in both patients. Though the utility and cost efficacy of RFA of peripheral nerves needs to be confirmed in well-designed trials we present these cases as an example of how this minimally invasive technique can safely provide analgesia in a difficult to treat cephalgia. Moreover if precise anatomical localization of the headache is possible then diagnostic blockade of the appropriate peripheral nerve may be performed followed by

    Subglottic stenosis of congenital origin or acquired within the first 12 months of life are challenging in many aspects. Surgical reconstruction is difficult due to the small anatomic dimensions. Tracheostomy is an additional risk factor attributing to mortality and should be avoided, if possible. In this paper, the most important types of subglottic stenosis in the first year of life are discussed. Conservative, endoscopic, and open surgical treatment options are presented and evaluated. Laryngotracheal reconstruction with autologous thyroid cartilage is the treatment of choice for the majority of significant subglottic stenosis cases in this age group. This technique is comparatively less invasive, versatile, and allows all options for open reconstruction using other techniques in case of recurrent stenosis. Subglottic stenosis in early infancy requires expertise and experience in diagnosis and treatment. Considering the limited incidence, these cases should be managed in a referral center.

  19. Cobalt Chloride Treatment Used to Ablate the Lateral Line System Also Impairs the Olfactory System in Three Freshwater Fishes.

    Full Text Available Fishes use multimodal signals during both inter- and intra-sexual displays to convey information about their sex, reproductive state, and social status. These complex behavioral displays can include visual, auditory, olfactory, tactile, and hydrodynamic signals, and the relative role of each sensory channel in these complex multi-sensory interactions is a common focus of neuroethology. The mechanosensory lateral line system of fishes detects near-body water movements and is implicated in a variety of behaviors including schooling, rheotaxis, social communication, and prey detection. Cobalt chloride is commonly used to chemically ablate lateral line neuromasts, thereby eliminating water-movement cues to test for mechanosensory-mediated behavioral functions. However, cobalt acts as a nonspecific calcium channel antagonist and could potentially disrupt function of all superficially located sensory receptor cells, including those for chemosensing. Here, we examined whether CoCl2 treatment used to ablate the lateral line system also impairs olfaction in three freshwater fishes, the African cichlid fish Astatotilapia burtoni, goldfish Carassius auratus, and the Mexican blind cavefish Astyanax mexicanus. To examine the impact of CoCl2 on the activity of peripheral receptors, we quantified DASPEI fluorescence intensity of the olfactory epithelium from fish exposed to control and CoCl2 solutions. In addition, we examined brain activation in olfactory processing regions of A. burtoni immersed in either control or cobalt solutions. All three species exposed to CoCl2 had decreased DASPEI staining of the olfactory epithelium, and in A. burtoni, cobalt treatment caused reduced neural activation in olfactory processing regions of the brain. To our knowledge this is the first empirical evidence demonstrating that the same CoCl2 treatment used to ablate the lateral line system also impairs olfactory function. These data have important implications for the use of

    Pathological involvement of the basivertebral nerve (BVN), an intraosseous vertebral nerve, may play a significant role in some forms of back pain. This study was designed to assess the feasibility and effects of thermal ablation of the lumbar basivertebral nerve in mature sheep. Sixteen adult female sheep weighing 65-80 kg were anesthetized and positioned for ventral recumbent surgery. Under fluoroscopic guidance, two bilarterally oposed 5mm active length rediofrequency (RF) electrodes (1.65mm diameter were perfutaneously placed in select lumbar vertebrae at a relative angle of 70 degrees with a 5 mm tip separation. The elctrodes were advanced to the region of the vertebral bodies which contained the BVN. A thermal dose of 95° C/720 seconds was administered. Animals were survived for 2, 14, 90, or 180 days post-treatment. Clinical, radiologic and pathologic investigations were performed to determine the effect of the heat on the BVN and associated tissues. Thermal damage to the basivertebral neurovascular bundle was characterized by early hemorrhage and necrosis, followed by inflammation and fibrosis. Although there wasa significant revascularization of the treated bone marow regions, there was no evidence of basivertebral nerve survival or regeneration regeneration. In addition to ablation of teh basivertebral nerovascular bundle, the areas receiving the greatest treatment demonstrated initial mild local osteolysis and demineralization of the vertebral body bone and regional depopulation of the vertebral bone marrow cellular elements. Significant bone remodeling in the affected areas had begun by 14 days post-treatment. Bone remodeling was characterized by conventional osteoblast proliferation, osteoid deposition, and mineralization. This study demonstrated the ability to accurately, reproducibly, and safely ablate the basivertebral nerve and neurovascular bundle in mature sheep using a fluoroscopically guided percutaneously delivered radiofrequency technique.

    Quadriceps tendon injuries and insufficiencies in total knee arthroplasty are rare, but are followed by a devastating complication that left untreated leads to a complete loss of function of the knee. This review article summarizes the functional anatomy, risk factors, and the prevalence and diagnosis of quadriceps tendon injuries, in addition to the possible management options for partial and complete ruptures. The treatment options are adapted according to the extent of the loss of function (partial, complete) and the duration of the injury (acute vs chronic). Furthermore, the choice of treatment should take into account the quality and availability of primary tissue, the patient's general health, along with their likely functional requirements. Conservative treatment is often justified in partial ruptures with good results. Complete ruptures require surgical intervention and multiple operative techniques are described. Treatment options for acute ruptures include direct primary repair with autogenous or synthetic tissue augmentation. In the case of chronic insufficiency and a lack of soft-tissue surroundings, reconstruction with the aid of a muscle flap or allograft tissue can be considered. All surgical intervention techniques used so far have been fraught with complications and rarely lead to satisfactory results. A new surgical approach to the reconstruction and augmentation of the extensor mechanism consists of the use of a synthetic mesh. The technique is described here in detail.

    ABSTRACT Purpose To describe our initial experience with radiofrequency ablation (RFA) of Bosniak IV renal cysts. Materials and Methods From 2010 to 2014, 154 renal tumor cases were treated with percutaneous thermal ablation, of which 10 cases (6.4%) from nine patients were complex renal cysts and were treated with radiofrequency ablation. Results All complex cysts were classified as Bosniak IV (four women and five men; mean age: 63.6 yrs, range: 33–83 years). One patient had a single kidney. Lesion size ranged from 1.5 to 4.1cm (mean: 2.5cm) and biopsy was performed on four cysts immediately before the procedure, all of which were malignant (two clear cell and two papillary carcinoma). Mean volume reduction of complex cysts was 25% (range: 10–40%). No patients required retreatment with RFA and no immediate or late complications were observed. The follow-up of Bosniak IV cysts had a median of 27 months (interquartile range [IQR], 23 to 38) and no recurrence or significant loss of renal function were observed. Conclusions Mid-term follow-up of the cases in our database suggests that image-guided percutaneous RFA can treat Bosniak IV cysts with very low complication rates and satisfactorily maintain renal function.

    Objectives The aim of this study was to investigate factors affecting ablative efficiency of high intensity focused ultrasound (HIFU) for adenomyosis. Materials and methods In all, 245 patients with adenomyosis who underwent ultrasound guided HIFU (USgHIFU) were retrospectively reviewed. All patients underwent dynamic contrast-enhanced magnetic resonance imaging (MRI) before and after HIFU treatment. The non-perfused volume (NPV) ratio, energy efficiency factor (EEF) and greyscale change were set as dependent variables, while the factors possibly affecting ablation efficiency were set as independent variables. These variables were used to build multiple regression models. Results A total of 245 patients with adenomyosis successfully completed HIFU treatment. Enhancement type on T1 weighted image (WI), abdominal wall thickness, volume of adenomyotic lesion, the number of hyperintense points, location of the uterus, and location of adenomyosis all had a linear relationship with the NPV ratio. Distance from skin to the adenomyotic lesion's ventral side, enhancement type on T1WI, volume of adenomyotic lesion, abdominal wall thickness, and signal intensity on T2WI all had a linear relationship with EEF. Location of the uterus and abdominal wall thickness also both had a linear relationship with greyscale change. Conclusion The enhancement type on T1WI, signal intensity on T2WI, volume of adenomyosis, location of the uterus and adenomyosis, number of hyperintense points, abdominal wall thickness, and distance from the skin to the adenomyotic lesion's ventral side can all be used as predictors of HIFU for adenomyosis.

    Otitis media (OM) has numerous presentations in children. Together with conventional medical therapies aimed to prevent and/or treat OM, a rising number of complementary and alternative medicine (CAM) treatment options can be offered. Since OM is common in children, parents may ask healthcare professionals about possible CAM therapies. Many physicians feel that their knowledge is limited regarding these therapies, and that they desire some information. Therefore, we conducted a literature review of CAM therapies for OM, taking into account that many of these treatments, their validity and efficacy and have not been scientifically demonstrated.We performed a search in MEDLINE (accessed via PubMed) using the following terms: "CAM" in conjunction with "OM" and "children. Retrieved publications regarding treatment of OM in children which included these terms included randomized controlled trials, prospective/retrospective studies, and case studies.The following CAM options for OM treatment in children were considered: acupuncture, homeopathy, herbal medicine/phytotherapy, osteopathy, chiropractic, xylitol, ear candling, vitamin D supplement, and systemic and topical probiotics. We reviewed each treatment and described the level of scientific evidence of the relevant publications.The therapeutic approaches commonly associated with CAM are usually conservative, and do not include drugs or surgery. Currently, CAM is not considered by physicians a potential treatment of OM, as there is limited supporting evidence. Further studies are warranted in order to evaluate the potential value of CAM therapies for OM. PMID:26871802

    Full Text Available Background: Radiofrequency (RF ablation procedures to electrically isolate the pulmonary veins (PV from the left atrium are frequently used to treat atrial fibrillation. We hypothesized that changes in PV size after RF ablation would correlate with the volume of ostial PV scar as assessed by high resolution late gadolinium enhancement (LGE cardiovascular magnetic resonance (CMR. Methods: The study cohort included 23 subjects. Contrast enhanced CMR of the PV was obtained before and 42 ± 18 days after RF ablation. High-resolution LGE CMR of the left atrium and PV was obtained using a 3D, ECG triggered, navigator gated technique. Results: A total of 85 PV were analyzed. Imaging after RF ablation demonstrated a reduction in PV diameter from 22 ± 7 mm to 21 ± 6 mm after (p = 0.001 with a reduction in cross-sectional area (CSA from 285 ± 141 to 246 ± 110 (p < 0.001. There was a significant correlation of PV ostial normalized scar volume with the change in PV diameter (r =-0.21, p =0.049 and CSA (r =-0.28, p =0.010 after AF ablation. PV in the highest quartile for PV scar had the greatest reduction in diameter and CSA (p <0.05 for both. Conclusion: PV size decreases significantly after RF ablation for the treatment of AF. The change in PV size is linearly related to the quantity of scar at the PV ostium

    Levosimendan, an inotropic agent, that enhances myofilament response to calcium, increases myocardial contraction and could therefore be beneficial in verapamil intoxication. Here, we report the case of a 60-year-old patient with clinically severe verapamil poisoning who presented with shock, bradycardia, and sopor. Standard therapy including high-dose inotropes failed to ameliorate the signs of intoxication. But additional therapy with levosimendan led to rapid improvement. Based on this observation, the literature is reviewed focusing on utilization of levosimendan in the treatment of calcium channel blocker overdose. We suggest to consider levosimendan as additional treatment option in patients with cardiovascular shock due to verapamil intoxication that are refractory to standard management.

    Radiofrequency catheter ablation (RFA) represents the first line therapy of the cavotricuspid isthmus-dependent atrial flutter (CTI-AFL) with a high efficacy and low secondary effects. RFA of CTI-dependent AFL can be performed by using various types of ablation catheters. Recent evaluations comparing externally cooled tip RFA (ecRFA) catheters and large-tip (8 mm) catheters have revealed that these catheters have a higher efficacy for CTI-AFL ablation compared to 4-mm catheters. The reliability of RFA catheters for AFL is variable and an optimal catheter selection may enhance the RFA effectiveness. The main goal of this article is to review the elements that improve the management of CTI RFA. Preliminary examinations of histopathologic and anatomical elements that may interfere with conventional CTI RFA are presented. Experimental studies concerning the electrobiology of large-tip and cooled-tip catheters are compared. The different catheter designs between cooled-tip and 8-mm-tip catheters are examined (size of the deflectable curve, rotation stability, and size of the distal nonsteerable catheter part) because of their critical role in CTI RFA results. A thorough review of clinical trials of each catheter is presented, and comparison of both catheters in this clinical setting is analyzed. In addition, the role of CTI morphology on AFL RF duration is underlined such as the value of right atrial angiography as an adjunct tool for CTI RFA catheter selection. Based on randomized studies, 8-mm-tip catheters seem to be more effective for ablation in case of straight angiographic isthmus morphology. On the other hand, ecRFA catheters appear to be more effective in cases of complex CTI anatomy or difficult CTI RFA. To reduce X-ray exposition and RFA application time, few studies report that CTI angiographic evaluation before RFA allows a catheter selection based on both CTI morphology and length. Moreover, preliminary data of randomized studies showed that an

    The combination of renal cell carcinoma (RCC) and hepatocellular carcinoma (HCC) is extremely rare, and the prognosis for patients with these two cancers is poor. In the past decade, molecular targeted therapy and radiofrequency ablation (RFA) have emerged and these treatments are now playing an increasingly important role in the management of patients with advanced primary RCC and HCC. In this case report, a 72-year-old male patient diagnosed as having RCC invading the renal vein and grade I-II HCC was treated with RFA and sorafenib (400 mg twice daily). After 3 months of this combination treatment, an evaluation of his target lesions showed stable disease (SD), and progression-free survival (PFS) times were 28 months weeks for RCC and 16 months weeks for HCC. Overall survival (OS) was 40 weeks.

    Melanoma remains a serious form of skin cancer in Europe and worldwide. Localized, early-stage melanomas can usually be treated with surgical excision. However, the prognosis is poorer for patients with advanced disease. Before 2011, treatment for advanced melanoma included palliative surgery and/or radiotherapy, and chemotherapy with or without immunotherapy, such as interleukin-2. As none of these treatments had shown survival benefits in patients with advanced melanoma, European guidelines had recommended that patients be entered into clinical trials. The lack of approved first-line options and varying access to clinical trials meant that European clinicians relied on experimental regimens and chemotherapy-based treatments when no other options were available. Since 2011, ipilimumab, an immuno-oncology therapy, and vemurafenib and dabrafenib, targeted agents that inhibit mutant BRAF, have been approved by the European Medicines Agency for the treatment of advanced melanoma. More recently, the MEK inhibitor, trametinib, received European marketing authorization for use in patients with BRAF mutation-positive advanced melanoma. In 2014, the anti-PD-1 antibody nivolumab was approved as a first-line therapy in Japan. Whereas nivolumab and another anti-PD-1 antibody, pembrolizumab, were approved as second-line therapies in the USA, their recent approval in Europe are for first-line use based on new clinical trial data in this setting. Together these agents are changing clinical practice and making therapeutic decisions more complex. Here, we discuss current and emerging therapeutic options for the first-line treatment of advanced melanoma, and how these therapies can be optimized to provide the best possible outcomes for patients.

    Purpose: This retrospective study evaluated the feasibility, efficacy, and safety of combining transcatheter arterial embolization (TAE) with radiofrequency thermal ablation (RFA) in a single session for the treatment of technically unresectable liver-only malignancies. Methods: From May 2006 to January 2011, a total of 30 patients affected by liver metastases with single or multiple unresectable liver-only lesions underwent a combined treatment with TAE followed by RFA in the same session, for a total of 36 treated lesions. Patients were extrapolated from a cohort of patients discussed within the weekly institutional tumor board. TAE was performed by using 100 {mu}m microspheres; RFA was performed immediately after TAE by positioning the electrode needle via ultrasound and/or computed tomographic guidance. Local tumor responses and procedure-related complications were evaluated. Results: Completion of both procedures was obtained in all patients for all 36 lesions. Liver lesions had a maximum axial diameter ranging 16-59 mm. Postintervention unenhanced ablated areas ranged 28-104 mm in maximum axial diameter. Safety margins ranged 1-30.5 mm. Complete response, defined as complete devascularization at computed tomography, was obtained in all treated lesions for a maximum period of 12 months. Tumor relapse was observed in one patient at 12 months. Sixteen patients developed new liver lesions or progressive systemic disease during follow-up. Nine patients were still disease-free. Seven patients died as a result of systemic progressive disease. One major treatment-related complication was observed. Conclusions: In patients with technically unresectable liver-only malignancies, single-session combined TAE-RFA is an effective and safe treatment.

  6. Solidification of radioactive liquid wastes, Treatment options for spent resins and concentrates - 16405

    International Nuclear Information System (INIS)

    Ion exchange is one of the most common and effective treatment methods for liquid radioactive waste. However, spent ion exchange resins are considered to be problematic waste that in many cases require special approaches and pre-conditioning during its immobilization to meet the acceptance criteria for disposal. Because of the function that they fulfill, spent ion exchange resins often contain high concentrations of radioactivity and pose special handling and treatment problems. Another very common method of liquid radioactive waste treatment and water cleaning is the evaporation or diaphragm filtration. Both treatment options offer a high volume reduction of the total volume of liquids treated but generate concentrates which contain high concentrations of radioactivity. Both mentioned waste streams, spent resins as well as concentrates, resulting from first step liquid radioactive waste treatment systems have to be conditioned in a suitable manner to achieve stable waste products for final disposal. Spent resin and concentrate treatment often appear as a specific task in decommissioning projects, because in the past those waste streams typically had been stored in tanks for the lifetime of the plant and needs to be retrieved, conditioned and packed prior to dismantling activities. Additionally a large amount of contaminated liquids will be generated by utilizing decontamination processes and needs to be processed further on. Such treatment options need to achieve waste products acceptable for final disposal, because due to the closure of the site no interim storage can be envisaged. The most common method of treatment of such waste streams is the solidification in a solid matrix with additional inactive material like cement, polymer etc. In the past good results have been achieved and the high concentration of radioactivity can be reduced by adding the inactive material. On the other hand, under the environment of limited space for interim storage and the absence

    Posttraumatic stress disorder (PTSD) is a well-studied mental health condition with existing guidelines and algorithms for treatment of PTSD. Those guidelines, while acknowledging an increased complexity, fail to provide clear PTSD treatment guidelines when an individual has a concurrent traumatic brain injury (TBI) diagnosis. Therefore, a literature review along with an accompanying case presentation is presented to demonstrate the minimum necessary considerations for approaching treatment of this complex population. Treatment approaches must be lead by providers that have the expertise and training necessary to consider all facets of the patient and their potential options. The provider must consider the pathophysiology of PTSD and TBI and be capable of leading a team to identify the patient's source(s) of dysfunction, current cognitive abilities, and potential indications for psychotropic medications and/or other types of therapeutic intervention.

    Full Text Available Warit Waewsawangwong, Pirapat Ruchiwit, James I Huddleston, Stuart B Goodman Department of Orthopedic Surgery, Stanford University, Stanford, CA, USA Abstract: Surgical treatment for late stage (post-collapse osteonecrosis of the femoral head is controversial. In these situations, the outcome of joint preservation procedures is poor. There are several arthroplasty options for late-stage disease. The clinical outcomes of hemiarthroplasty and hemiresurfacing are unpredictable because of progressive acetabular cartilage degeneration. Total hip resurfacing may be associated with further vascular insult to the femoral head and early failure of the implant. Total hip replacement with metal-on-conventional polyethylene bearing surfaces has been the gold standard, but implant survivorship is limited in young active patients due to wear and osteolysis. Newer alternative bearing surfaces may have improved wear characteristics, but their durability must be confirmed in longer-term studies.

    To report the biopsy findings of osteoid osteoma (OO) and OO-mimicking lesions, assess their distinctive multidetector computed tomography (MDCT) features and evaluate treatment by radiofrequency ablation (RFA). In this multicentric retrospective study, 80 patients (54 male, 26 female, mean age 24.1 years, range 5-48) with presumed (clinical and MDCT features) OO were treated by percutaneous RFA between May 2002 and June 2009. Per-procedural biopsies were always performed. The following MDCT features were assessed: skeletal distribution and location within the bone, size, central calcification, surrounding osteosclerosis and periosteal reaction. Clinical success of RFA was evaluated. Histopathological diagnoses were: 54 inconclusive biopsies, 16 OO, 10 OO-mimicking lesions (5 chronic osteomyelitis, 3 chondroblastoma, 1 eosinophilic granuloma, 1 fibrous dysplasia). OO-mimicking lesions were significantly greater in size (p = 0.001) and presented non-significant trends towards medullary location (p = 0.246), moderate surrounding osteosclerosis (p = 0.189) and less periosteal reaction (p = 0.197), compared with OO. Primary success for ablation of OO-mimicking lesions was 100% at 1 month, 85.7% at 6 and 12 months, and 66.7% at 24 months. Secondary success was 100%. Larger size, medullary location, less surrounding osteosclerosis and periosteal reaction on MDCT may help differentiate OO-mimicking lesions from OO. OO-mimicking lesions are safely and successfully treated by RFA. (orig.)

    Background Over the past two decades,the clinical presentation of renal masses has evolved,where the rising incidence of small renal masses (SRMs) and concomitant minimal invasive treatments have led to noteworthy changes in paradigm of kidney cancer.This study was to perform a proportional meta-analysis of observational studies on perioperative complications and oncological outcomes of partial nephrectomy (PN) and radiofrequency ablation (RFA).Methods The US National Library of Medicine's life science database (Medline) and the Web of Science were exhaustly searched before August 1,2013.Clinical stage 1 SRMs that were treated with PN or RFA were included,and perioperative complications and oncological outcomes of a total of 9 565 patients were analyzed.Results Patients who underwent RFA were significantly older (P <0.001).In the subanalysis of stage T1 tumors,the major complication rate of PN was greater than that of RFA (laparoscopic partial nephrectomy (LPN)/robotic partial nephrectomy (RPN):7.2%,open partial nephrectomy (OPN):7.9%,RFA:3.1%,both P <0.001).Minor complications occurred more frequently after RFA (RFA:13.8%,LPN/RPN:7.5%,OPN:9.5%,both P <0.001).By multivariate analysis,the relative risks for minor complications of RFA,compared with LPN and OPN,were 1.7-fold and 1.5-fold greater (both P <0.01),respectively.Patients treated with RFA had a greater local progression rate than those treated by PN (RFA:4.6%,LPN/RPN:1.2%,OPN:1.9%,both P <0.001).By multivariate analysis,the local tumor progression for RFA versus LPN/RPN and OPN were 4.5-fold and 3.1-fold greater,respectively (both P <0.001).Conclusions The current data illustrate that both PN and RFA are viable strategies for the treatment of SRMs.Compared with PN,RFA showed a greater risk of local tumor progression but a lower major complication rate,which is considered better for poor candidates.PN is with no doubt the golden treatment for SRMs,and LPN has been widely accepted

Hysterectomy, the most common surgical treatment of AUB, has significant morbidity, low mortality, long recovery, and high associated health care costs. Global endometrial ablation (GEA provides a surgical alternative with reduced morbidity, cost, and recovery time. The NovaSure® system utilizes unique radiofrequency impedance-based GEA technology. This study evaluated cost effectiveness of AUB treatment with NovaSure ablation versus other GEA modalities and versus hysterectomy from the US commercial and Medicaid payer perspectives. Methods: A health state transition (semi-Markov model was developed using epidemiologic, clinical, and economic data from commercial and Medicaid claims database analyses, supplemented by published literature. Three hypothetical cohorts of women receiving AUB interventions were simulated over 1-, 3-, and 5-year horizons to evaluate clinical and economic outcomes for NovaSure, other GEA modalities, and hysterectomy. Results: Model analyses show lower costs for NovaSure-treated patients than for those treated with other GEA modalities or hysterectomy over all time frames under commercial payer and Medicaid perspectives. By Year 3, cost savings versus other GEA were $930 (commercial and $3,000 (Medicaid; cost savings versus hysterectomy were $6,500 (commercial and $8,900 (Medicaid. Coinciding with a 43%–71% reduction in need for re-ablation, there were 69%–88% fewer intervention/reintervention complications for NovaSure-treated patients versus other GEA modalities

    The emergence of high-level resistance to ceftriaxone is giving rise to serious concern about absence of effective treatment options to cure gonococcal infections. Increasing the dosage regimen can be applied to ceftriaxone and azithromycin, but the emergence of high-level resistance has already been reported. Spectinomycin is another active drug but has low efficacy in the treatment of pharyngeal gonorrhoea. Conventional antibiotics could be introduced for gonococcal treatment, but they have some limitations, such as the absence of clinical trials and breakpoint. Combining antibiotics is another promising method to cure patients and to prevent the emergence of resistance. The most important strategy to maintain the efficacy of antibiotics is rapid detection and dissemination control of novel resistant isolate. PMID:26690658

    Full Text Available In this clinical observation is shown the data of the patient who was previously undergone paranodal ablation of atrial-ventricular junction for the treatment of atrioventricular (AV nodal reentrant tachycardia. Radiofrequency ablation of right lower isthmus for treatment of the paroxysmal form of atrial flutter was made for the patient. Sick sinus node syndrome and paroxysmal form of atrial fibrillation were diagnosed. Then dual-chamber pacemaker was implanted. Antiarrhythmic therapy about the persistent form of atrial fibrillation had no effect. The decision for the implementation of radio frequency modification of atrioventricular connection using right ventriclar access failed because of the lack of verification of the His bundle's spike. Using retrograde access through the aorta we managed to create AV blockade of III degree. Taking into account the fact that in 1990-ies patients with atrioventricular nodal reentrant tachycardia were operated using paranodal ablation of the AV node using extracorporeal circulation, this case has a practical significance when endovascular catheter modification of AV nodal conduction in this category of patients is made.

    Full Text Available Generalized aggressive periodontitis results in rapid destruction of the periodontium and can lead to early tooth loss in the affected individuals if not diagnosed early and treated appropriately. The diagnostic features of the disease are characteristic, but the clinical presentation and patterns of destructions may vary between patients. Successful management of the disease is challenging especially if diagnosed at advanced stages of the disease, but not impossible with the current therapeutic choices for the disease. A vast array of treatment modalities is available which can be employed in the treatment of generalized aggressive periodontitis with varying success rates, but a definite guideline for the management is yet to be formulated. However, with the exponential rate of developments in periodontal research, regenerative therapy, tissue engineering, and genetic technologies, the future seems promising in regard to options at managing the disease. This paper attempts to describe the clinical and radiographic diagnostic features and the current treatment options along with a suggested protocol for comprehensive management of generalized aggressive periodontitis patients with case reports and a brief review.

    Full Text Available Background: Cerebral alveolar echinococcosis (AE is a rare but lethal parasitic disease. Its pathogenesis remains poorly understood. Currently there is no widely accepted methods for its surgical treatment. Aims: To discuss the surgical treatment options. Settings and Design: Hospital-based observational study. Materials and Methods: Patients who had surgery for cerebral AE during 2001 and 2007 were the subjects of the study. According to the lesion location and volume, patients have been allocated to either massive resection group or radical piecemeal resection group. Postoperatively, all patients received long-term aldendazole therapy in view of the associated hepatic involvement and were follow-up in the clinic. Results: Of the six patients with cerebral AE who were operated during the study period, four had massive resection and two had radical piece meal resection. None of the patients had postoperative neurological worsening and there was improvement in the neurological status in all the patients except for the patient with blindness. Of the 4 patients in massive resection group, two patients died during the follow-up, one because of liver failure and the other due to hydrocephalus. The remaining four patients were back to their normal activities and none had recurrence of the disease during the follow-up. Conclusions: Although radical massive resection is generally regarded as the surgical method treatment for cerebral AE, radical piecemeal resection can be a reasonable, effective alternative management option, especially when massive resection might result in unavoidable morbidity and mortality.

    Objective To evaluate the efficacy of treatment options for patients with recurrent ovarian cancer. Methods From 1990 to 2000, 54 patients with recurrent ovarian cancer primarily treated in Peking Union Medical College Hospital were selected and reviewed. All the clinical data related to the recurrent tumor were collected. Twoside P values for differences in survival were calculated by the Cox regression model. Results The platinum-free interval > 6 months and the surgery followed by salvage chemotherapy prolonged survival time of the patients with recurrent ovarian cancer (95% CI = 0. 153-0. 987, P = 0. 047; 95 % CI = 1.611-10. 914,P =0. 003, respectively). The increased number of chemotherapy cycles ( > 10 months) offered some benefit on the survival (95 % CI = 0. 110-1. 090, P = 0. 070). The initiation of treatment and chemotherapy regiments failed to demonstrate an improvement in survival. Conclusion The treatment options for patients with recurrent ovarian cancer depend on the platinum-free-interval of the patients. A strategy of secondary surgical cytoreduction followed by salvage chemotherapy is suggested for the patients with platinum-sensitive disease.

  20. New direct oral anticoagulants--current therapeutic options and treatment recommendations for bleeding complications.

    2012-10-01

    To date, clinical studies show that the incidence of spontaneous bleeding with new direct oral anticoagulants (DOAs) is comparable to that of established anticoagulants. However, unlike vitamin K antagonists, there are currently no clinically available antidotes or approved reversal agents for new DOAs. Restoring normal coagulation is important in many cases, such as emergency surgeries, serious bleedings, or anticoagulant overdosing. Attempts have been made to restore normal coagulation after treatment with new DOAs using compounds such as recombinant activated factor VII (rFVIIa), prothrombin complex concentrate (PCC), or FEIBA (factor eight inhibitor bypassing activity). Limited pre-clinical data and even less clinical evidence are available on the usefulness of these methods in restoring normal coagulation for the emergency management of critical bleeding episodes. Evaluating the utility of DOAs is further complicated by the fact that it is unknown how predictive established test systems are of the bleeding risks. Clinical practice requires further evaluation of the emergency management options for the new DOAs to define the agents and the doses that are most useful. Furthermore, patients receiving long-term treatment with a DOA are likely to undergo elective surgery at some point, and there is lack of evidence regarding perioperative treatment regimens under such conditions. This review summarises potential bleeding management options and available data on the new DOAs. PMID:22782297

    To determine whether patient specific numerical simulations of irreversible electroporation (IRE) of the prostate correlates with the treatment effect seen on follow-up MR imaging. Computer models were created using intra-operative US images, post-treatment follow-up MR images and clinical data from six patients receiving IRE. Isoelectric contours drawn using simulation results were compared with MR imaging to estimate the energy threshold separating treated and untreated tissue. Simulation estimates of injury to the neurovascular bundle and rectum were compared with clinical follow-up and patient reported outcomes. At the electric field strength of 700 V/cm, simulation estimated electric field distribution was not different from the ablation defect seen on follow-up MR imaging (p = 0.43). Simulation predicted cross sectional area of treatment (mean 532.33 ± 142.32 mm(2)) corresponded well with the treatment zone seen on MR imaging (mean 540.16 ± 237.13 mm(2)). Simulation results did not suggest injury to the rectum or neurovascular bundle, matching clinical follow-up at 3 months. Computer simulation estimated zone of irreversible electroporation in the prostate at 700 V/cm was comparable to measurements made on follow-up MR imaging. Numerical simulation may aid treatment planning for irreversible electroporation of the prostate in patients. PMID:27026913

    Full Text Available In chronic thromboembolic pulmonary hypertension, stenoses or obstructions of the pulmonary arteries due to organized thrombi can cause an elevation in pulmonary artery resistance, which in turn can result in pulmonary hypertension. Chronic thromboembolic pulmonary hypertension can be cured surgically by pulmonary endarterectomy; however, patients deemed unsuitable for pulmonary endarterectomy due to lesion, advanced age, or comorbidities have a poor prognosis and limited treatment options. Recently, advances have been made in balloon pulmonary angioplasty for these patients, and this review highlights this recent progress.

    Objective To investigate the suitable ablation temperature for renal sympathetic-nerve ablation for hypertension. Methods The canine model of hypertension was established by abdominal aortic constriction. Twenty healthy hybrid dogs, weighing 15 to 20 kg, were randomly divided into treatment group which underwent renal sympathetic-nerve ablation and control group (n = 10). Ten dogs in treatment group were randomly divided into 45 ℃ and 50 ℃ groups (n = 5) according to predetermined ablation temperature. Ablation was carried out in 1 month after modeling. Systolic blood pressure (SBP) , diastolic blood pressure (DBP) and mean arterial pressure (MAP) were measured before modeling as well as before ablation, 1 and 2 months after ablation, respectively. Renal angiography was carried out in treatment group in 2 months after ablation. Renal artery vessels were examined pathologically with HE staining. Results At 1 month after modeling, blood pressure (BP) was increased significantly in both groups (P <0.01). At 1 month after ablation, SBP was reduced significantly in treatment group (P <0.05). At 2 months after ablation, SBP, DBP and MAP were markedly lower than those before ablation ( P < 0.05, 0.01) as well as those in control group (P < 0.05, 0.01). No artery stenosis or other abnormality was observed in renal angiography review. Pathological results revealed that renal vascular injury was much more severe in 50 ℃ group than in 45 ℃ group. Conclusion 45 ℃ can be used as a conventional ablation temperature for renal sympathetic-nerve ablation for hypertension.%目的 探讨肾交感神经射频消融术治疗高血压的适宜消融温度.方法 成年健康杂种犬20只,雌雄不拘,体质量15~25 kg,建立腹主动脉缩窄型高血压模型后,随机分为治疗组(行双侧肾交感神经射频消融术)和对照组(n=10).治疗组根据预置消融温度随机分为45℃和50℃组(n=5).20只犬分别于建模前、建模后1(射频消融术前)、2(

    Bone and soft tissue tumor ablation has reached widespread acceptance in the locoregional treatment of various benign and malignant musculoskeletal (MSK) lesions. Many principles of ablation learned elsewhere in the body are easily adapted to the MSK system, particularly the various technical aspects of probe/antenna design, tumoricidal effects, selection of image guidance, and methods to reduce complications. Despite the common use of thermal and chemical ablation procedures in bone and soft...

    The purpose of this study was to analyze the costs of magnetic resonance imaging (MRI)-guided laser ablation and to compare them with the costs of surgery in the treatment of osteoid osteoma. Seven patients with osteoid osteoma were treated with MRI-guided interstitial laser ablation during 1 year. The reference material consisted of six patients whose osteoid osteoma was treated surgically by either superficial or deep excision with metallic fixation. The costs were analyzed by using activity-based cost accounting. The mean cost of the MRI-guided laser ablation was 2,392 euros and of the excision of superficially located osteoid osteoma 1,807 euros. The cost of excision of deeply located osteoma with metallic fixation was considerably higher (4,996 euros). This was due to the higher material, personnel, and ward costs. The cost of MRI-guided laser ablation of osteoid osteoma was higher than the cost of surgical excision of a superficial osteoma but considerably lower than the cost of excision of a deeply located osteoma where metallic fixation was needed. When the number and mean cost of sick days or days of restricted weight bearing were also included, the cost of MRI-guided laser ablation was lower than the costs of either superficial or deep excision.

    The goal of focal therapy is to achieve long-term oncological control by eradicating only the clinically significant focus/foci of cancer within the prostate, while preserving erectile function and continence. Anterior prostate cancers may have a PZ or TZ origin and share commonalities in location and biology. While anterior prostate cancers previously constituted a diagnostic blind spot in the prostate and were often not detected or discovered late, with the rapid dissemination of advanced imaging and biopsy techniques, they can now be identified at an earlier, organ-confined stage due to MR imaging and targeted biopsies. Due to their anterior location, they represent a therapeutic target that allows for thorough ablation of the cancer focus/foci with an adequate margin while remaining far from the neurovascular bundles bilaterally. However, the TZ origin cancers are mostly anterior to the distal urethra close to the apex and the striated sphincter. Men having early stage anterior cancers may represent good candidates to achieve a balance between oncological control and functional preservation with focal therapy. Thus, this class of tumor based on location, along with the proposed treatment, represents a novel form of targeted image-guided therapy. PMID:27502428

  9. Options to reduce greenhouse gas emissions during wastewater treatment for agricultural use

    International Nuclear Information System (INIS)

    Treatment of primarily-domestic sewage wastewater involves on-site greenhouse gas (GHG) emissions due to energy inputs, organic matter degradation and biological nutrient removal (BNR). BNR causes both direct emissions and loss of fertilizer value, thus eliminating possible reduction of emissions caused by fertilizer manufacture. In this study, we estimated on-site GHG emissions under different treatment scenarios, and present options for emission reduction by changing treatment methods, avoiding BNR and by recovering energy from biogas. Given a typical Israeli wastewater strength (1050 mg COD l−1), the direct on-site GHG emissions due to energy use were estimated at 1618 and 2102 g CO2-eq m−3, respectively, at intermediate and tertiary treatment levels. A potential reduction of approximately 23–55% in GHG emissions could be achieved by fertilizer preservation and VS conversion to biogas. Wastewater fertilizers constituted a GHG abatement potential of 342 g CO2-eq m−3. The residual component that remained in the wastewater effluent following intermediate (oxidation ponds) and enhanced (mechanical–biological) treatments was 304–254 g CO2-eq m−3 and 65–34 g CO2-eq m−3, respectively. Raw sludge constituted approximately 47% of the overall wastewater fertilizers load with an abatement potential of 150 g CO2-eq m−3 (385 kg CO2-eq dry tonne−1). Inasmuch as anaerobic digestion reduced it to 63 g CO2-eq m−3 (261 kg CO2-eq dry tonne−1), the GHG abatement gained through renewable biogas energy (approx. 428 g CO2-eq m−3) favored digestion. However, sludge composting reduced the fertilizer value to 17 g CO2-eq m−3 (121 kg CO2-eq dry tonne−1) or less (if emissions, off-site inputs and actual phytoavailability were considered). Taking Israel as an example, fully exploiting the wastewater derived GHG abatement potential could reduce the State overall GHG emissions by almost 1%. This demonstrates the possibility of optional carbon credits which

    Full Text Available Symptoms of psychosis such as hallucinations and delusions can be intrusive and unwanted and often remain treatment-resistant. Due to recent progress in basic and clinical sciences, novel approaches such as sleep-based interventions are increasingly becoming offered to address the physical and mental health issues of people with severe mental illness. While the primary outcome is to improve sleep, studies have demonstrated that interventions that target symptoms of insomnia can also produce improvements in the severity of psychotic symptoms, quality of life and functional outcomes. This study presents qualitative data on the attitudes and preferences of people with schizophrenia and schizo-affective disorders to three different types of therapies for insomnia (standard pharmacological, melatonin-based, and cognitive and/or behaviour therapy. Interviews included discussions regarding the perceived advantages and limitations of different therapies, enablers to taking up the preferred option, as well as personal strategies that have helped respondents with sleep problems in the past. Results showed that, when given the choice, these individuals prefer psychological and behavioural-type therapy to other sleep interventions because of its potential to support and empower them in taking responsibility for their own recovery. Pharmacological therapies, by contrast, are viewed as useful in managing acute sleep problems, but only as a short-term solution. Overall, the findings underscore the need for patients’ active engagement when making decisions about treatment options.

    Pityriasis lichenoides (PL) is a skin condition of unclear etiology that occurs not uncommonly in childhood. It is often classified into the acute form, pityriasis lichenoides et varioliformis acuta (PLEVA), and the chronic form, pityriasis lichenoides chronica (PLC). We performed a comprehensive review of the English-language literature using the PubMed database of all cases of childhood PL reported from 1962 to 2014 and summarized the epidemiology, clinical features, treatment options, and prognosis of this condition in children. The proposed etiologies are discussed, including its association with infectious agents, medications, and immunizations and evidence for PL as a lymphoproliferative disorder. We found an average age of PL onset of 6.5 years, with a slight (61%) male predominance. We also found that PLEVA and PLC tend to occur with equal frequency and that, in many cases, there is clinical and histopathologic overlap between the two phenotypes. When systemic therapy is indicated, we propose that oral erythromycin and narrowband ultraviolet B phototherapy should be first-line treatment options for children with PL since they have been shown to be effective and well tolerated. In most cases, PL follows a benign course with no greater risk of cutaneous T-cell lymphoma, although given the rare case reports of transformation, long-term follow-up of these patients is recommended.

    Full Text Available The diagnosis and treatment of symptomatic chondral lesions in young and active middle-aged patients continues to be a challenging issue. Surgeons must differentiate between incidental chondral lesions from symptomatic pathology that is responsible for the patient's pain. A thorough history, physical examination, and imaging work up is necessary and often results in a diagnosis of exclusion that is verified on arthroscopy. Treatment of symptomatic glenohumeral chondral lesions depends on several factors including the patient's age, occupation, comorbidities, activity level, degree of injury and concomitant shoulder pathology. Furthermore, the size, depth, and location of symptomatic cartilaginous injury should be carefully considered. Patients with lower functional demands may experience success with nonoperative measures such as injection or anti-inflammatory pharmacotherapy. When conservative management fails, surgical options are broadly classified into palliative, reparative, restorative, and reconstructive techniques. Patients with lower functional demands and smaller lesions are best suited for simpler, lower morbidity palliative procedures such as debridement (chondroplasty and cartilage reparative techniques (microfracture. Those with higher functional demands and large glenohumeral defects will usually benefit more from restorative techniques including autograft or allograft osteochondral transfers and autologous chondrocyte implantation (ACI. Reconstructive surgical options are best suited for patients with bipolar lesions.

    Full Text Available Bladder carcinoma is frequently seen in the geriatric age group. Environmental factors and life style are risk fac - tors in the development of bladder carcinoma. Smoking is one of the most important risk factor and passive smok - ing should be taken into consideration in married couples. Additionally quality of life is now a well-recognized and important outcome measure that should be considered when deciding the treatment option for bladder cancer. In this case presentation, risk factors and environmental fac tors in the development of synchronous bladder tumors in a couple married for 43 years are evaluated. We would also like to emphasize the effects of treatments for blad der tumors with and without muscle invasion on the qual ity of life of the geriatric population in need of home care.

    Due to the esthetic necessity required nowadays, the multidisciplinary treatment became a fundamental step in the restoration success. When the patient exhibits dental agenesis of one or more elements, he can show difficulty in social interactions. The age of the patient is a limiting factor to esthetic procedures, however, it should be evaluated as a real indicative with each case. The utilization of semi-direct restorations is a viable option due the cost, esthetic and improvement of physical and mechanical properties. The purpose of this paper is to present a case detailing the confection and cementation of anterior semi-direct restorations aimed at an anatomic reestablishment associated with integrated treatment with periodontics and orthodontics.

    Cardiovascular shock due to verapamil intoxication is often refractory to standard resuscitation methods. Recommended therapy includes prevention of further absorption of the drug, inotropic therapy, calcium gluconate, and hyperinsulinemia/euglycemia therapy. Often further measures are needed such as ventricular pacing or mechanical circulatory support. Still, mortality remains high. Levosimendan, an inotropic agent, that enhances myofilament response to calcium, increases myocardial contraction and could therefore be beneficial in verapamil intoxication. Here, we report the case of a 60-year-old patient with clinically severe verapamil poisoning who presented with shock, bradycardia, and sopor. Standard therapy including high-dose inotropes failed to ameliorate the signs of intoxication. But additional therapy with levosimendan led to rapid improvement. Based on this observation, the literature is reviewed focusing on utilization of levosimendan in the treatment of calcium channel blocker overdose. We suggest to consider levosimendan as additional treatment option in patients with cardiovascular shock due to verapamil intoxication that are refractory to standard management.

    In keeping with international trends, lung cancer incidence and mortality are increasing among the Irish population with many patients presenting with advanced disease that excludes the potential for curative management. Consequently palliative treatment options for this patient group are being increasingly explored with various degrees of success. Endobronchial stenosis represents a particularly challenging area of management among these patients and a number of techniques have been described without the identification of a single gold standard. We report our experience of the first time use of endobronchial cryotherapy in Ireland with reference to a case series, including an example of its use in the management of benign disease, in order to support patients with borderline lung function and enable definitive palliative treatment.

    Neurovascular free-muscle transfer for facial reanimation was performed as a secondary reconstructive procedure for 45 patients with facial paralysis resulting from ablative surgery in the parotid region. This intervention differs from neurovascular free-muscle transfer for treatment of established facial paralysis resulting from conditions such as congenital dysfunction, unresolved Bell palsy, Hunt syndrome, or intracranial morbidity, with difficulties including selection of recipient vessels and nerves, and requirements for soft-tissue augmentation. This article describes the authors' operative procedure for neurovascular free-muscle transfer after ablative surgery in the parotid region. Gracilis muscle (n = 24) or latissimus dorsi muscle (n = 21) was used for transfer. With gracilis transfer, recipient vessels comprised the superficial temporal vessels in 12 patients and the facial vessels in 12. For latissimus dorsi transfer, recipient vessels comprised the facial vessels in 16 patients and the superior thyroid artery and superior thyroid or internal jugular vein in four. Facial vessels on the contralateral side were used with interpositional graft of radial vessels in the remaining patient with latissimus dorsi transfer. Cross-face nerve grafting was performed before muscle transfer in 22 patients undergoing gracilis transfer. In the remaining two gracilis patients, the ipsilateral facial nerve stump was used as the primary recipient nerve. Dermal fat flap overlying the gracilis muscle was used for cheek augmentation in one patient. In the other 23 patients, only the gracilis muscle was used. With latissimus dorsi transfer, the ipsilateral facial nerve stump was used as the recipient nerve in three patients, and a cross-face nerve graft was selected as the recipient nerve in six. The contralateral facial nerve was selected as the recipient nerve in 12 patients, and a thoracodorsal nerve from the latissimus dorsi muscle segment was crossed through the upper lip

    The ability to vaporize extremely thin layers of epithelial tissue without any char and with minimal thermal necrosis is extremely advantageous in the treatment of superficial lesions of the external genitalia. We present a novel CO2 laser `SwiftLase' flashscan technology capable of providing char free ablation of 3 mm diameter lesions with only 150 micron residual thermal necrosis depth at power level as low as 10 watts. These power levels are achievable with a small transportable CO2 laser. The SwiftLaser is a miniature opto- mechanical scanner which homogeneously covers a 3 mm diameter surface with a 0.1 mm spot size focused beam within 0.1 seconds. The instantaneous beam's dwelling time is 1 millisecond. The instantaneous power density level at the focal point is higher than the threshold for char free ablation, thus providing a large char free ablation crater. Since depth of each ablated layer is 0.1 mm, the depth of treatment can be precisely controlled. The SwiftLaser technology has extensively and successfully been used in the last two years for the treatment of HPV in female lower tracts (Vulvectomy). The same technique may be performed with extramammary Paget's disease of the vulva, penile condylomata, and other epithelial disorders of the external genitalia without damage to surrounding healthy tissue. Technique and clinical results will be discussed.

As a consequence, many PD patients suffer with reduced health-related quality of life. To address quality of life in depressed PD patients, we reviewed the literature on the health correlates of depression in PD (eg, cognitive function, etiology of depression in PD, and treatment options (ie, antidepressants, electroconvulsive therapy, and psychotherapy. The current review is unique in its focus on psychosocial aspects, as well as neuropathological factors, of depression in PD. Overall, we conclude that neurochemical (eg, serotonin and psychosocial factors (eg, coping style, self-esteem, and social support contribute to the affective disturbances found in this neuropsychiatric population. Therefore, we recommend that a multidisciplinary (eg, pharmacotherapeutic, psychoeducational, and/or psychotherapeutic approach to treatment be taken with depressed PD patients.Keywords: depression, Parkinson’s disease, health outcomes, treatment options

Primary tumors underwent MWA followed by platinum-based doublet chemotherapy. Modified response evaluation criteria in solid tumors (mRECIST) and RECIST were used to evaluate therapeutic response. Complications were assessed using the National Cancer Institute Common Toxicity Criteria (version 3.0).ResultsMWA was administered to 39 tumors in 39 patients. The mean and median diameters of the primary tumor were 3.84 cm and 3.30 cm, respectively, with a range of 1.00–9.00 cm. Thirty-three (84.6 %) patients achieved a partial response. No correlation was found between MWA efficacy and clinicopathologic characteristics. For chemotherapy, 11 patients (28.2 %) achieved a partial response, 18 (46.2 %) showed stable disease, and 10 (25.6 %) had progressive disease. The overall objective response rate and disease control rate were 28.2 and 74.4 %, respectively. The median progression-free survival time was 8.7 months (95 % CI 5.5–11.9). The median overall survival time was 21.3 months (95 % CI 17.0–25.4). Complications were observed in 22 (56.4 %) patients, and grade 3 adverse events were observed in 3 (7.9 %) patients.ConclusionsPatients with advanced NSCLC could benefit from MWA in combination with chemotherapy. Complications associated with MWA were common but tolerable.

    AIM: To summarize the effects of laparoscopic ethanol injection and radiofrequency ablation (L-EI-RFA), thora-coscopic (T-EI-RFA) and open-surgery assisted EI-RFA (O-EI-RFA) under general anesthesia for the treatment of hepatocellular carcinoma (HCC).METHODS: Time-lag performance of RFA after ethanol injection (Time-lag PEI-RFA) was performed in all cases. The volume of coagulated necrosis and the applied energy for total and per unit volume coagulated necrosis were examined in the groups treated under general (group G) or local anesthesia (group L).RESULTS: The results showed that the total applied energy and the applied energy per unit volume of whole and marginal, coagulated necrosis were significantly larger in group G than those in the group L, resulting in a larger volume of coagulated necrosis in the group G. The rate of local tumor recurrence within one year was extremely low in group G.CONCLUSION: These results suggest that EI-RFA, under general anesthesia, may be effective for the treatment of HCC because a larger quantity of ethanol and energy could be applied during treatment under pain-free condition for the patients.

    Full Text Available OBJECTIVE: To explore the therapeutic efficacy and safety of malignant liver tumor treatment by radiofrequency ablation (RA combined with low frequency ultrasound radiation with microbubbles (LFURM. METHODS: Retrospective analysis of 25 patients with malignant hepatic tumors treated by RA/LFURM in the Department of Hepatobiliary Surgery of Kunming General Hospital affiliated to Chengdu Military District, PLA from January 2010 to June 2011. Ultrasound guided RA was performed, which was followed one week later by LFURM. Basal contrast ultrasound, liver function tests, and serum alpha fetoprotein (AFP were obtained, and repeated 3 and 6 months after treatment. T-test and chi-square were used to compare parametric and non-parametric variables respectively. RESULTS: In 17 cases, gross tumor volume was significantly reduced 6 months after treatment while mean tumor showed a reduction of 50% compared to pre-treatment values. In 7 cases gross tumor volumes reduction was partial, but surrounding tumor tissue showed blood flow signals. One patient had no reduction in gross tumor volume. Levels of serum alanine aminotransferase (ALT, aspartate aminotransferase (AST, total bilirubin (TBIL, alpha fetoprotein (AFP decreased significantly 6 months after treatment (all p<0.05. No tumor recurrence was seen during the 6 month follow-up. Quality of life scores (QOL were good in 21 patients (84%, improved in 2 patients (8%, unchanged in 1 patient (4% and got worst in 1 patient (4%. Karnofsky scores (KPS improved in 19 patients (76%, remained unchanged in 5 patients (2% and got worst in 1 patient (4%. Both QOL and KPS changes were statistically significant (P<0.05. CONCLUSION: RA/LFURM treatment of liver tumors is efficient and safe, and can reduce the gross tumor volumes and protect liver function.

All patients received conventional ultrasound as well as CEUS examination before, immediately after and 12–24 h after MW, in order to detect variations of echo and characteristics of blood supply. t-Tests were used to compare the hyperecho area on gray-scale ultrasound to immediately after ablation non-enhanced CEUS measurements, as well as to compare the immediately after ablation non-enhanced CEUS measurements to the 12–24 h after ablation measurements. Results: Immediately after ablation, the average hyperecho area in gray-scale was 82.20 ± 72.32 cm3; the average non-enhancement area was 76.34 ± 70.63 cm3 by CEUS, showing a strong correlation (r = 0.997, P 3 and average 12–24 h after ablation was 98.29 ± 78.25 cm3; no statistically significant difference was detected between the two time points (P > 0.05). Conclusions: Measurements made by hyperechoic range on gray-scale ultrasonography is strongly correlated to the no enhancement area by CEUS. The hyperechoic range on gray-scale image can represent the ablated area immediately after MW.

    The survival of most patients with both unresectable hepatic and pulmonary metastases of colorectal cancer is poor. In this retrospective study, we investigated the efficacy of computed tomography (CT)-guided radiofrequency ablation (RFA) and systemic chemotherapy plus hepatic artery infusion of floxuridine (HAI-FUDR). Sixty-one patients were selected from 1,136 patients with pulmonary and hepatic metastases from colorectal cancer. Patients were treated with RFA and systemic chemotherapy plus HAI-FUDR (ablation group, n=39) or systemic chemotherapy plus HAI-FUDR (FUDR group, n=22). Patients in the two groups were matched by sex, age, number of metastases, and calendar year of RFA or FUDR. Survival data were evaluated by using univariate and multivariate analyses. Clinical characteristics were comparable between the two groups. Al patients in the ablation group underwent RFA and chemotherapy. Median fol ow-up was 56.8 months. The 1-, 3-, and 5-year overall survival (OS) rates were 97%, 64%, and 37%, respectively, for the ablation group, and 82%, 32%, and 19%, respectively, for the FUDR group. The 1-, 3-, and 5-year survival rates after metastasis were 97%, 49%, and 26%for the ablation group, and 72%, 24%, and 24%for the FUDR group, respectively. The median OS times were 45 and 25 months for the ablation and FUDR groups, respectively. In the multivariate analysis, treatment al ocation was a favorable independent prognostic factor for OS (P = 0.001) and survival after metastasis (P = 0.009). These data suggest that the addition of RFA to systemic chemotherapy plus HAI-FUDR improves the survival of patients with both unresectable hepatic and pulmonary metastases from colorectal cancer.

    The aim of this study was to validate multislice computed tomography (MSCT) venography measurements of pulmonary vein (PV) diameters vs conventional pulmonary venography (CPV), and to assess the reproducibility of MSCT data. The study included 21 consecutive patients with atrial fibrillation who were planned for cryothermal ablation of PVs. One day before ablation, all patients underwent CPV and contrast-enhanced non-gated MSCT venography. The MSCT was repeated 3 months after ablation. The CPV images of the treated PVs (n=40) were analyzed and compared with the results of MSCT measurements. Reproducibility of MSCT venography-based data was assessed by interobserver (n=84 PVs) and interexamination (n=44 PVs) variability. Pre-treatment PV diameters on MSCT and CPV showed good correlation (r=0.87, p<0.01; 18.9{+-}2.3 mm, 188.5{+-}2.4 mm, respectively). Interobserver agreement and interexamination reproducibility were good (r=0.91, r=0.82, respectively, p<0.01), with narrow limits of agreement (Bland and Altman method). The MSCT venography allows accurate and reproducible assessment of PVs. It can be used both in non-invasive planning of treatment for ablative therapy and in the follow-up of patients.

    The MUG (Montreal Urban Community) treatment plant produces approximately 270 tons of dry sludge daily (270 tds/day) during the physico-chemical treatment of wastewater. Recently, this treatment plant endowed a system of drying and granulation of sludge for valorization as an agricultural fertilizer having a capacity of 70 tds/day (25% of the daily sludge production). However, the metal content (mainly Cu and Cd) of the sludge surpasses the norms for biosolids valorization. In order to solve this problem, a demonstration project, from the lab scale to the industrial pilot plant, was carried out to test the Metix-AC technology for the removal of metals. A strongly metal-loaded filtrate was generated during the sludge decontamination. Tests concerned the study of the metal recovery by total precipitation and selective precipitation, as well as the use of alternative products for the metal precipitation. Other works consisted to simulate the acid filtrate recirculation from the decontaminated sludge (25% of the total volume) in the untreated sludge (75% of the total volume) intended for the incineration. The total precipitation with hydrated limeappearedeffectivefortherecoveryof metals (87% Cd, 96% Cr, 97% Cu, 98% Fe, 71% Ni, 100% Pb, 98% Zn). However, this option entails the production of an important quantity of metallic residue, which should be disposed of expensively as dangerous material. The selective iron precipitation does not appear to bean interesting option because the iron in solution within the leached sludge was principally present in the form of ferrous iron, which cannot be precipitated at pH lower than five. On the other hand, the use of commercial precipitating agents (TMT-15, CP-33Z, CP-NB and CPX) without pH adjustment of filtrate gave good results for the recovery of Cu and, to a lesser degree for the recovery of Pb. However, the efficiency for the other metals' (Cd, Cr, Fe, Ni and Zn) recovery was weaker (< 25%). Finally, the acid filtrate

    Odontoma is the most common odontogenic benign tumor, and the treatment of choice is generally surgical removal. After excision, bone grafts may be necessary depending on the need for further treatment, or the size and location of the odontoma. Although the osteogenic capacity of a demineralized tooth was verified as early as 1967 by Urist and many other investigators, the cumbersome procedure, including a long demineralization time, may be less than comfortable for clinicians. A modified ultrasonic technology, with periodic negative pressure and temperature control, facilitated rapid and aseptic preparation of demineralized teeth for bone grafts. This approach reduces the demineralization time dramatically (≤80 minutes), so that the graft material can be prepared chairside on the same day as the extraction. The purpose of this article is to describe two cases of large compound odonotomas used as graft material prepared chairside for enucleation-induced bony defects. These two clinical cases showed favorable wound healing without complications, and good bony support for future dental implants or orthodontic treatment. Finally, this report will suggest the possibility of recycling the benign pathologic hard tissue as an alternative treatment option for conventional bone grafts in clinics.

    Full Text Available The purpose of this review of the literature was to present treatment options for early stage pyriform sinus cancer. Squamous cell carcinoma of the pyriform sinus, as the most frequent cancer arising from the hypopharynx, is rarely diagnosed in its early stage. Based on evidence from retrospective studies, conservation surgery and definitive radiotherapy are considered the available treatment modalities for patients presenting with stage T1 and T2 pyriform sinus carcinomas without clinical evidence of neck lymph node metastases, offering similar results with respect to disease control and functional organ preservation. Also, the high risk of occult metastatic nodal disease even in the earliest stage of pyriform sinus cancer entails elective neck dissection or elective neck irradiation to be considered mandatory. However, for patients with early stage pyriform sinus cancer, no level 1 study exists in which conservation surgery is compared with radiotherapy alone for the evaluation of local control or survival. Randomized multicenter controlled trials evaluating efficacy of conservation surgery and definitive radiotherapy, and correctly interpreting functional outcome for each of the treatment procedures examined are necessary to obtain sufficient evidence to influence the decision in the choice of the most effective treatment for early pyriform sinus cancer.

    Urinary incontinence and lower urinary tract symptoms are highly prevalent in late life and are strongly associated with dementia and frailty. Incontinence is extremely common among those living in long-term care and is most commonly due to urgency incontinence. Although national and international guidelines for continence care exist, they often fail to consider the complex comorbidity found in patients with dementia and are often not followed; continence practices in long-term care may promote rather than prevent incontinence. The majority of those with dementia living in the community can be managed successfully with standard treatments, both pharmacological and non-pharmacological; the expectations and aims of treatment of both the patient and their caregivers should be considered. A dementia diagnosis does not preclude management of incontinence, but treatment options may be more limited in those with advanced dementia who are unable to retain information and modify behaviors. High-quality data to guide the choice of pharmacological agent in those with dementia are lacking. Oxybutynin has been shown to have significant adverse cognitive effects, but data to support the use of trospium, solifenacin, darifenacin, and fesoterodine are limited. No data are available for mirabegron. Neither age, frailty, nor dementia should be considered a barrier to pharmacological management, but consideration should be given to the total anticholinergic load. Evidence to guide the treatment of incontinence in this vulnerable patient group is scarce, and available guidelines adapted for each individual's situation should be applied.

  14. Options to reduce greenhouse gas emissions during wastewater treatment for agricultural use.

    Treatment of primarily-domestic sewage wastewater involves on-site greenhouse gas (GHG) emissions due to energy inputs, organic matter degradation and biological nutrient removal (BNR). BNR causes both direct emissions and loss of fertilizer value, thus eliminating possible reduction of emissions caused by fertilizer manufacture. In this study, we estimated on-site GHG emissions under different treatment scenarios, and present options for emission reduction by changing treatment methods, avoiding BNR and by recovering energy from biogas. Given a typical Israeli wastewater strength (1050mg CODl(-1)), the direct on-site GHG emissions due to energy use were estimated at 1618 and 2102g CO(2)-eq m(-3), respectively, at intermediate and tertiary treatment levels. A potential reduction of approximately 23-55% in GHG emissions could be achieved by fertilizer preservation and VS conversion to biogas. Wastewater fertilizers constituted a GHG abatement potential of 342g CO(2)-eq m(-3). The residual component that remained in the wastewater effluent following intermediate (oxidation ponds) and enhanced (mechanical-biological) treatments was 304-254g CO(2)-eq m(-3) and 65-34g CO(2)-eq m(-3), respectively. Raw sludge constituted approximately 47% of the overall wastewater fertilizers load with an abatement potential of 150g CO(2)-eq m(-3) (385kg CO(2)-eq dry tonne(-1)). Inasmuch as anaerobic digestion reduced it to 63g CO(2)-eq m(-3) (261kg CO(2)-eq dry tonne(-1)), the GHG abatement gained through renewable biogas energy (approx. 428g CO(2)-eq m(-3)) favored digestion. However, sludge composting reduced the fertilizer value to 17g CO(2)-eq m(-3) (121kg CO(2)-eq dry tonne(-1)) or less (if emissions, off-site inputs and actual phytoavailability were considered). Taking Israel as an example, fully exploiting the wastewater derived GHG abatement potential could reduce the State overall GHG emissions by almost 1%. This demonstrates the possibility of optional carbon credits which

    Global reserves of mineral phosphorus are finite and the recycling of phosphorus from wastewater, a significant sink for phosphorus, can contribute to a more sustainable use. In Germany, Switzerland, and the Netherlands, an increasing percentage of municipal sewage sludge is incinerated and the contained phosphorus is lost. This paper reviews current technologies and shows that a complete phosphorus recovery from wastewater is technically feasible. Depending on the composition of the sewage sludge ash (SSA), there are various options for phosphorus recovery that are presented. Iron-poor SSAs can be used directly as substitute for phosphate rock in the electrothermal phosphorus process. SSAs with low heavy metal contents can be used as fertilizer without prior metal elimination. Ashes not suitable for direct recycling can be processed by thermal processes. Operators of wastewater treatment plants can additionally influence the ash composition via the selection of precipitants and the control of (indirect) dischargers. This way, they can choose the most suitable phosphorus recovery option. For sewage sludge that is co-incinerated in power plants, municipal waste incinerators or cement kilns phosphorus recovery is not possible. The phosphorus is lost forever. PMID:22053454

    2009-01-01

    Autosomal dominant polycystic kidney disease (ADPKD) represents a slowly progressing cystic kidney disorder which evolves into end-stage renal disease in the majority of patients. Currently, there are no established treatments to retard the progression of the disease, but several promising therapeutic options are being tested in ongoing clinical trials. An inherent dilemma for the investigation of therapies in ADPKD is the dissociation of the early onset and constant rate of cyst growth from the delayed but accelerated loss of renal function. In order to prevent the latter, one needs to act on the former, i.e. current belief by experts in the field is that (1) retardation of cyst growth will ultimately improve the loss of glomerular filtration rate, and (2) cyst volume is an ideal surrogate parameter for outcome in early ADPKD. The present review will discuss the utility and the techniques for kidney and cyst volume measurements to assess disease progression in ADPKD, and summarizes ongoing clinical trials testing novel therapeutic options.

    Vertical transmission has become the most common mode of transmission of hepatitis C virus (HCV) in children. The rate of perinatal transmission from an HCVinfected mother to her child ranges from 2% to 5% and the prevalence of HCV in children in developed countries ranges between 0.1% and 0.4%. Spontaneous viral clearance seems to be dependent on the genotype and has been reported between 2.4%-25%. For chronically infected patients, treatment with recombinant polyethylene glycol (PEG)-interferon α-2b and daily ribavirin has now been approved as standard treatment for children 2-17 years of age. In five large prospective studies, a total of 318 children and adolescents aged 3-17 years were treated either with subcutaneous PEG-interferon α-2b at a dose of 1-1.5 μg/kg or 60 μg/m2 once a week in combination with oral ribavirin (15 mg/kg per day) or PEG-interferon α-2a with ribavirin. Subjects with genotype 1 and 4 received the medication for 48 wk and individuals with genotype 2 and 3 mainly for 24 wk. Overall sustained viral response (SVR) was achieved in 193/318 (60.7%) of treated patients. Stratified for genotype; 120/234 (51%) with genotype 1, 68/73 (93%) with genotype 2/3, and 6/11 (55%) with genotype 4 showed SVR. Relapse rate was between 7.7% and 17%. Overall, treatment was well tolerated; however,notable side effects were present in approximately 20%. According to recent experiences in the treatment of chronic hepatitis C in children and adolescents, a combination of PEG-interferon α with ribavirin has been found to be well tolerated and highly efficacious, particularly in individuals with genotype 2/3. Thus, this treatment can be recommended as standard of care until more effective treatment options will become available for genotype 1 patients.

    Full Text Available Elizabeth Ralevski, Lening A Olivera-Figueroa, Ismene Petrakis Yale University School of Medicine, Department of Psychiatry, VA Connecticut Healthcare System, West Haven, CT, USA Background: Although posttraumatic stress disorder (PTSD and alcohol use disorders (AUD frequently co-occur there are no specific treatments for individuals diagnosed with these comorbid conditions. The main objectives of this paper are to review the literature on pharmacological options for PTSD and comorbid AUD, and to summarize promising behavioral and alternative interventions for those with these dual diagnoses. Methods: We conducted a comprehensive search on PsycINFO and MEDLINE/PubMed databases using Medical Subject Headings terms in various combinations to identify articles that used pharmacotherapy for individuals with dual diagnoses of PTSD and AUD. Similar strategies were used to identify articles on behavioral and alternative treatments for AUD and PTSD. We identified and reviewed six studies that tested pharmacological treatments for patients with PTSD and comorbid AUD. Results: The literature on treatment with US Food and Drug Administration approved medications for patients with dual diagnosis of PTSD and AUD is very limited and inconclusive. Promising evidence indicates that topiramate and prazosin may be effective in reducing PTSD and AUD symptoms in individuals with comorbidity. Seeking safety has had mixed efficacy in clinical trials. The efficacy of other behavioral and alternative treatments (mindfulness-based, yoga, and acupuncture is more difficult to evaluate since the evidence comes from small, single studies without comparison groups. Conclusion: There is a clear need for more systematic and rigorous study of pharmacological, behavioral, and alternative treatments for patients with dual diagnoses of PTSD and AUD.

    Purpose: Since the 20{sup th} century, radiotherapy (RT) has been used for treatment of symptomatic splenomegaly (SM). SM occurs in association with hematologic disorders. The purpose of this analysis was to determine the indication, treatment concepts, and efficiency of RT. Material and Methods: Clinical features, treatment concepts, and outcome data during the past 20 years were analyzed. Endpoints were pain relief, symptomatic and hematological response, and treatment-related side effects. Results: From 1989-2009, a total of 122 patients received 246 RT courses because of symptomatic SM. Overall 31 patients had chronic myelogenous leukemia (CML), 37 had chronic lymphocytic leukemia (CLL), 23 had osteomyelofibrosis (OMF), 17 had polycythemia vera (PV), 5 had acute myelogenous leukemia, 4 had idiopathic thrombocytopenic purpura (ITP), 3 had non-Hodgkin lymphoma (NHL), and 2 had multiple myeloma (MM). Patients were treated with {sup 60}Co gamma rays or 5-15MV photons. The fraction size ranged from 10-200 cGy and the total dose per treatment course from 30-1600 cGy. Significant pain relief was achieved for 74.8% of the RT courses given for splenic pain. At least 50% regression was attained for 77% of the RT courses given for SM. 36 patients died within 2 months due to the terminal nature of their disease. Of the RT courses applied for cytopenia, 73.6% achieved a significant improvement of hematological parameters and reduction of transfusion need. Notable hematologic toxicities were reported < EORTC/RTOG II . Conclusion: The present analysis documents the efficacy of RT. In addition, RT as a palliative treatment option for symptomatic SM should not be forgotten. (orig.)

    A 15 year-old grey Thoroughbred gelding presented for investigation of chronic weight loss and recent onset of respiratory difficulty. Clinical examination confirmed tachypnoea with increased respiratory effort. Thoracic ultrasound examination detected pleural effusion. The dyspnoea was related to the large volume of pleural effusion and, following post-mortem examination, to the presence of a large mediastinal mass. Multiple pigmented masses, likely melanomas, were detected peri-anally. Thoracic radiography, cytological examination of the pleural fluid and a fine needle aspirate of a thoracic mass led to a presumptive diagnosis of malignant melanoma and this was confirmed at post mortem examination. Further metastatic spread to the central nervous system and right guttural pouch was also identified. In conclusion this case manifests the potential malignant behaviour of equine melanomas, and a review of proposed therapies for melanoma treatment highlights the therapeutic options and current areas of research.

    Migraine is a very common type of headache. With a prevalence of 10-12%, migraine ranks 19th among diseases causing worldwide morbidity. Number of studies have shown a high prevalence of patent foramen ovale (PFO) in patients with migraine, especially migraine with aura. The right to left shunting of blood in a PFO could serve as a conduit for chemicals that would exert a trigger effect on hyper excitable neurons leading to the development of migraine. Furthermore patients with PFO and migraine also show a marked improvement in their symptoms after percutaneous closure of the PFO. This review is a close look at this association and also explores whether subsequent closure of the shunt can be looked upon as a viable treatment option.

    The recognition of lower extremity venous disease as a significant cause of morbidity and lower quality of life, afflicting up to 25 % of Western populations, has led to rapid and drastic improvements in treatment options as well as an increasing awareness of the disease. Superficial venous disease, a frequent medical problem encountered in clinical practices, is now a common reason for referral to providers offering a spectrum of interventions. Venous guidelines have been set forth by the American Venous Forum and Society for Vascular Surgery covering simple spider veins to chronic venous ulcerations. (Gloviczki et al.

    Full Text Available Intravaginal culture (IVC, also called INVO (intravaginal culture of oocytes, is an assisted reproduction procedure where oocyte fertilization and early embryo development are carried out within a gas permeable air-free plastic device, placed into the maternal vaginal cavity for incubation. In the present study we assessed the outcome of the INVO procedure, using the recently designed INVOcell device, in combination with a mild ovarian stimulation protocol. A total of 125 cycles were performed. On average 6.5 oocytes per cycle were retrieved, and a mean of 4.2 were placed per INVOcell device. The cleavage rate obtained after the INVO culture was 63%. The procedure yielded 40%, 31.2%, and 24% of clinical pregnancy, live birth, and single live birth rates per cycle, respectively. Our results suggest that the INVO procedure is an effective alternative treatment option in assisted reproduction that shows comparable results to those reported for existing IVF techniques.

  5. Renal Artery Embolization - A First Line Treatment Option For End-Stage Hydronephrosis

    International Nuclear Information System (INIS)

    Conventionally poorly functioning hydronephrotic kidneys have been removed if they are symptomatic. In our unit, patients are offered renal artery embolization as an alternative treatment option. Patients and Methods: Fifteen patients (11 male, 4 female) with a mean age of 32.9 yr (20-51 yrs) have undergone renal artery embolization for symptomatic hydronephrosis with poor function. Mean follow-up was 64.13 weeks (range 14-200). All patients had loin pain and hydronephrosis. Twelve patients had primary pelvi-ureteric junction obstruction (PUJO). Two patients had poorly functioning hydronephrotic kidneys secondary to chronic calculous obstruction. One patient had chronic pain in an obstructed but reasonably functioning kidney following a previous pyeloplasty for PUJO which demanded intervention. Mean split function on renography was 11% (range 0-46%). Selective renal artery embolization was carried out under antibiotic cover using a 7 Fr balloon occlusion catheter and absolute alcohol, steel coils, and polyvinyl alcohol particles.Results: Nine patients developed post-embolization syndrome of self-limiting pain and pyrexia with no evidence of sepsis. One patient required readmission with this condition. One patient developed a hematoma at the puncture site. Mean hospital stay was 2.3 days. Fourteen patients are happy with the result and are completely pain free. One patient has minor discomfort but is delighted with the result. Nine patients have had follow-up ultrasound confirming resolution of the hydronephrosis. Conclusion: Renal artery embolization is an effective, safe, well-tolerated minimally invasive treatment option in end-stage hydronephrosis and we routinely offer it as an alternative to nephrectomy

    Full Text Available Abstract Background Hypofractionated stereotactic radiotherapy (HFSRT is one salvage treatment option in previously irradiated patients with recurrent malignant glioma. We analyzed the results of HFSRT and prognostic factors in a single-institution series. Methods Between 1997 and 2003, 19 patients with recurrent malignant glioma (14 glioblastoma on most recent histology, 5 anaplastic astrocytoma were treated with HFSRT. The median interval from post-operative radiotherapy to HFSRT was 19 (range 3–116 months, the median daily single dose 5 (4–10 Gy, the median total dose 30 (20–30 Gy and the median planning target volume 15 (4–70 ml. Results The median overall survival (OS was 9.3 (1.9-77.6+ months from the time of HFSRT, 15.4 months for grade III and 7.9 months for grade IV tumors (p = 0.029, log-rank test. Two patients were alive at 34.6 and 77.6 months. OS was longer after a total dose of 30 Gy (11.1 months than after total doses of Conclusion HFSRT with conservative total doses of no more than 30 Gy is safe and leads to similar OS times as more aggressive treatment schemes. In individual patients, HFSRT in combination with other salvage treatment modalities, was associated with long-term survival.

    Full Text Available Abstract In order to be optimally effective, continuing training programmes for health-care professionals need to be tailored so that they target specific knowledge deficits, both in terms of topic content and appropriate intervention strategies. A first step in designing tailored treatment programmes is to identify the characteristics of the relevant health-care professional group, their current levels of content and treatment knowledge, the estimated prevalence of drug and alcohol problems among their patients and their preferred options for receiving continuing education and training. This study reports the results of a survey of 53 primary care physicians working in Iran. The majority were male, had a mean age of 44 years and saw approximately 94 patients per week. In terms of their patients' drug use, primary care physicians thought most patients with a substance use problem were male, women were most likely to use tobacco (52%, opium (32% and marijuana/hashish and young people were most likely to use tobacco, alcohol, marijuana and heroin. Counselling and nicotine patches were the treatments most commonly provided. Although the majority (55% reported referring patients to other services, more than a third did not. Most primary care physicians reported being interested in attending further training on substance abuse issues. The implications of these data for ongoing education and training of primary care physicians in Iran are discussed.

    Sustainability has strong implications on the practice of engineering. Life cycle assessment (LCA) is an appropriate methodology for assessing the sustainability of a wastewater treatment plant design. The present study used a LCA approach for comparing alternative wastewater treatment processes for small and decentralised rural communities. The assessment was focused on two energy-saving systems (constructed wetland and slow rate infiltration) and a conventional one (activated sludge process). The low environmental impact of the energy-saving wastewater treatment plants was demonstrated, the most relevant being the global warming indicator. Options for reduction of life cycle impacts were assessed including materials used in construction and operational lifetime of the systems. A 10% extension of operation lifetime of constructed wetland and slow rate infiltration systems led to a 1% decrease in CO2 emissions, in both systems. The decrease in the abiotic depletion was 5 and 7%, respectively. Also, replacing steel with HDPE in the activated sludge tank resulted in a 1% reduction in CO2 emission and 1% in the abiotic depletion indicator. In the case of the Imhoff tank a 1% reduction in CO2 emissions and 5% in the abiotic depletion indicator were observed when concrete was replaced by HDPE. PMID:17802833

  9. Low-grade MALT lymphoma of the stomach: a review of treatment options

    International Nuclear Information System (INIS)

    Purpose: Low-grade mucosa-associated lymphoid tissue (MALT) lymphoma of the stomach (MLS) is often associated with the presence of Helicobacter pylori (H. pylori) bacteria. Eradication of the infection with antibiotic therapy may result in regression of the lymphoma. But when antibiotic treatment fails to reverse the malignant process or if H. pylori is absent, other treatment options should be considered. Because MLS is often confined to the stomach and regional lymph nodes, it is potentially curable with local therapy. Endoscopy and improved imaging, with endoscopic ultrasound (EUS) and computerized tomography (CT), have reduced the prior dependence on surgery for diagnosis and staging of gastric lymphomas. Methods and Results: This review details the advances in the diagnosis, classification, and imaging of MLS. We also describe the experience that supports the use of radiation therapy as the preferred treatment of MLS in patients who have not responded to antibiotic therapy or have not had evidence for H. pylori infection. Conclusions: Radiation therapy for MLS is not only effective and safe, but offers the significant advantage of low morbidity and gastric function preservation

  10. Characterization and treatment options of solid residues from waste to energy plants

    International Nuclear Information System (INIS)

    Solid residues from waste to energy plants represent important byproducts of the thermal treatment process, with significant implications in all the procedures involved in the selection of alternative technological process options, in the achievement of the consensus of residents in the area and in decisions related to plant siting. Most recent restrictions broadly applied in the field of atmospheric emission limits have further increase their relative contribution to the environmental burden of the plant as a whole, particularly for certain toxic trace elements of interest removed with very high efficiencies from flue gas, most frequently through simple transfer rather than conversion and thus significantly enriched in the final residues of the removal process. Following a broad introduction on the main qualitative and quantitative characteristics of all the residues typically arising from waste to energy plants (furnace slag, flyash from particulate removal, ash from dry and semidry flue gas control operations, sludge from wet scrubbers blowdown treatment), the paper reports on the main technologies for their treatment and final disposal actually adopted in full scale applications, as well as on the alternatives that might be prospected in the near future for achieving further reductions in the total release of contaminants from the plant as a whole, in accordance with most recently proposed regulation strategies for industrial activities based on the IPPC approach (Integrated Pollution Prevention and Control)

    Treatment of primarily-domestic sewage wastewater involves on-site greenhouse gas (GHG) emissions due to energy inputs, organic matter degradation and biological nutrient removal (BNR). BNR causes both direct emissions and loss of fertilizer value, thus eliminating possible reduction of emissions caused by fertilizer manufacture. In this study, we estimated on-site GHG emissions under different treatment scenarios, and present options for emission reduction by changing treatment methods, avoiding BNR and by recovering energy from biogas. Given a typical Israeli wastewater strength (1050 mg COD l{sup -1}), the direct on-site GHG emissions due to energy use were estimated at 1618 and 2102 g CO{sub 2}-eq m{sup -3}, respectively, at intermediate and tertiary treatment levels. A potential reduction of approximately 23-55% in GHG emissions could be achieved by fertilizer preservation and VS conversion to biogas. Wastewater fertilizers constituted a GHG abatement potential of 342 g CO{sub 2}-eq m{sup -3}. The residual component that remained in the wastewater effluent following intermediate (oxidation ponds) and enhanced (mechanical-biological) treatments was 304-254 g CO{sub 2}-eq m{sup -3} and 65-34 g CO{sub 2}-eq m{sup -3}, respectively. Raw sludge constituted approximately 47% of the overall wastewater fertilizers load with an abatement potential of 150 g CO{sub 2}-eq m{sup -3} (385 kg CO{sub 2}-eq dry tonne{sup -1}). Inasmuch as anaerobic digestion reduced it to 63 g CO{sub 2}-eq m{sup -3} (261 kg CO{sub 2}-eq dry tonne{sup -1}), the GHG abatement gained through renewable biogas energy (approx. 428 g CO{sub 2}-eq m{sup -3}) favored digestion. However, sludge composting reduced the fertilizer value to 17 g CO{sub 2}-eq m{sup -3} (121 kg CO{sub 2}-eq dry tonne{sup -1}) or less (if emissions, off-site inputs and actual phytoavailability were considered). Taking Israel as an example, fully exploiting the wastewater derived GHG abatement potential could reduce the State

    Pigmentation secondary to minocycline ingestion is an uncommon adverse event affecting 3.7-14.8% of treated individuals for which few effective therapies are available. Three patterns of minocycline pigmentation have a characteristic clinical and histological appearance. The pigment composition in each variety is different and occurs at varying skin depths. Accordingly, a tailored approach according to the type of minocycline pigmentation is crucial for treatment success. The purpose of this intervention was to evaluate the efficacy of non-ablative fractional photothermolysis in combination with the Q-switched alexandrite laser for the treatment of type I minocycline pigmentation on the face. A patient with type I minocycline pigmentation was treated with non-ablative 1550-nm fractional photothermolysis followed immediately by 755-nm Q-switched alexandrite laser and then observed clinically to determine the outcome of this modality. The patient was seen in clinic 1 month later following her single treatment session and 100% clearance of all blue facial pigment was observed. Non-ablative fractional photothermolysis in combination with the 755-nm Q-switched alexandrite laser should be considered for treatment of type I minocycline pigmentation. PMID:26718463

  14. Diode laser trans - scleral cyclo - ablation as a primary surgical treatment for primary open - angle glaucoma after maximum tolerated medical therapy

    International Nuclear Information System (INIS)

    The incidence rate and prevalence of glaucoma in Pakistan is similar to that of other dark - colored population countries. Primary trabeculectomy is still a preferred surgical approach. Diode laser is widely accepted as the therapy of choice in severe glaucoma cases. The purpose of this study was to deter-mine the role of Diode Laser Transscleral Cyclo-ablation as a primary surgical treatment option in Primary Open Angle Glaucoma after maximum tolerated medical therapy. This quasi - experimental study was con-ducted at Layton Rahmatullah Benevolent Trust Free Eye Care and Cancer Hospital, Lahore. Sixty patients fulfilling the inclusion criteria were selected from the Glaucoma unit for this study. 25 - 30 burns of Diode Laser were applied to 270 degrees avoiding 3 and 9 O clock positions, 1.5 mm posterior to the limbus. Laser was set at duration of 1 second and power between 1000 and 1500 mw. Patients were followed up for a period of one year. Results: Out of a total of 60 eyes with mean age 52.73 +- 7.40 years, 36 (60%) were male and 24 (40%) were female. The mean pre-operative Intra Ocular Pressure IOP was 41.0 +- 7.0 mmHg (The pre-operative IOP ranged from 28 mmHg to 60 mmHg). The mean post-operative IOP was 18.97 mmHg on day one, 16.75 mmHg at 1 week, 15.68 mmHg at 1 month, 15.00 mmHg at 6 months and by the end of a year it was about 14.15 mmHg (The post-operative IOP ranged from 6 mmHg to 52 mmHg). There was a significant drop of more than 50% of post-operative IOP as compared to pre-operative IOP. Conclusion: Diode Laser Transscleral Cycloablation is a practical, rapid, well - tolerated procedure that provides a significant lowering of intraocular pressure with few complications and can considered as alternative treatment in POAG if medical therapy fails.

    Full Text Available Pierre Chue,1 Justine K Lalonde21Department of Psychiatry, University of Alberta, Edmonton, AB, Canada; 2Roche SAS, Medical Affairs Department, Boulogne-Billancourt, FranceAbstract: The negative symptoms of schizophrenia represent an impairment of normal emotional responses, thought processes and behaviors, and include blunting or flattening of affect, alogia/aprosody, avolition/apathy, anhedonia, and asociality. Negative symptoms contribute to a reduced quality of life, increased functional disability, increased burden of illness, and poorer long-term outcomes, to a greater degree than positive symptoms. Primary negative symptoms are prominent and persistent in up to 26% of patients with schizophrenia, and they are estimated to occur in up to 58% of outpatients at any given time. Negative symptoms respond less well to medications than positive symptoms, and to date treatment options for negative symptoms have been limited, with no accepted standard treatment. Modest benefits have been reported with a variety of different agents, including second-generation antipsychotics and add-on therapy with antidepressants and other pharmacological classes. Recent clinical research focusing on negative symptoms target novel biological systems, such as glutamatergic neurotransmission. Different approaches include: enhancing N-methyl-D-aspartate receptor function with agents that bind directly to the glycine ligand site or with glycine reuptake inhibitors; influencing the metabotropic glutamate receptor (mGluR2/3 with positive allosteric modulators; and stimulating nicotinic acetylcholine receptors. In conclusion, the lack of clearly efficacious pharmacological treatments for the management of negative symptoms represents a significant unmet need, especially considering the importance of these symptoms on patient outcomes. Hence, further research to identify and characterize novel pharmacological treatments for negative symptoms is greatly needed

    Retained placenta remains therapeutic challenge in cattle. Certain traditional medicines are believed to be able to alleviate retained placenta condition and improve overall fertility in cows. The aim of the present study was to evaluate the efficacy of an herbal tincture for treatment of retained placenta. The herbal tincture was extracted from a combination of Herba Leonuri, Angelicae Sinensis Radix, Flos Carthami, Myrrha and Rhizoma Cyperi by percolation with 70% ethanol to a concentration of 0.5g crude herb/ml. Cows diagnosed with retained placenta (n=48) were randomly divided into one of two treatment groups (A and B), with animals in group A (n=26) receiving herbal tincture orally, and cows in group B (n=22) receiving oxytetracycline infusion into the uterus. Eighty six cows with no clinically visible pathological conditions, given birth alone and with no retained placenta diagnosis were included into control group (C). Retained placenta was expelled within 72h following initial treatment in 19 cows in group A, yet no cows in group B were recorded to expel placenta in the same time. The median number of days to first service (70.0 vs. 102.5 days; P<0.05) and median number of days open (76.0 vs. 134.0 days; P<0.01) were lower in group A than in group B. Percentage of cows pregnant within 100 days postpartum was the highest for animals in group A compared to controls (61.5% vs. 39.5%, P<0.05), and for animals in group B (61.5% vs. 22.7%; P<0.01). Herbal tincture used in the present study might facilitate expulsion of retained placenta and improve subsequent fertility, thus could present effective treatment option for retained placenta in cows.

    Full Text Available PURPOSE: To determine the effect of different drug-loaded nanocarriers (micelles and liposomes on delivery and treatment efficacy for radiofrequency ablation (RFA combined with nanodrugs. MATERIALS/METHODS: Fischer 344 rats were used (n = 196. First, single subcutaneous R3230 tumors or normal liver underwent RFA followed by immediate administration of i.v. fluorescent beads (20, 100, and 500 nm, with fluorescent intensity measured at 4-24 hr. Next, to study carrier type on drug efficiency, RFA was combined with micellar (20 nm or liposomal (100 nm preparations of doxorubicin (Dox; targeting HIF-1α or quercetin (Qu; targeting HSP70. Animals received RFA alone, RFA with Lipo-Dox or Mic-Dox (1 mg i.v., 15 min post-RFA, and RFA with Lipo-Qu or Mic-Qu given 24 hr pre- or 15 min post-RFA (0.3 mg i.v.. Tumor coagulation and HIF-1α or HSP70 expression were assessed 24 hr post-RFA. Third, the effect of RFA combined with i.v. Lipo-Dox, Mic-Dox, Lipo-Qu, or Mic-Qu (15 min post-RFA compared to RFA alone on tumor growth and animal endpoint survival was evaluated. Finally, drug uptake was compared between RFA/Lipo-Dox and RFA/Mic-Dox at 4-72 hr. RESULTS: Smaller 20 nm beads had greater deposition and deeper tissue penetration in both tumor (100 nm/500 nm and liver (100 nm (p<0.05. Mic-Dox and Mic-Qu suppressed periablational HIF-1α or HSP70 rim thickness more than liposomal preparations (p<0.05. RFA/Mic-Dox had greater early (4 hr intratumoral doxorubicin, but RFA/Lipo-Dox had progressively higher intratumoral doxorubicin at 24-72 hr post-RFA (p<0.04. No difference in tumor growth and survival was seen between RFA/Lipo-Qu and RFA/Mic-Qu. Yet, RFA/Lipo-Dox led to greater animal endpoint survival compared to RFA/Mic-Dox (p<0.03. CONCLUSION: With RF ablation, smaller particle micelles have superior penetration and more effective local molecular modulation. However, larger long-circulating liposomal carriers can result in greater intratumoral drug

    Full Text Available Abstract Background Mediastinitis is a severe complication after cardiac surgery. While improvement of prophylaxis and of medical and surgical therapy has reduced its incidence, the treatment of mediastinitis continues to be a challenging problem. Within this study, we report the successful use of daptomycin as supportive therapy in patients developing mediastinitis after open cardiac surgery. Methods The records of 21 consecutive patients who developed mediastinitis after cardiac surgery were retrospectively reviewed. After diagnosis, all patients received surgical debridement and antibiotic therapy with daptomycin. All patients were followed up to death or discharge. Results Clinical improvement after combined surgical and antibiotic therapy with daptomycin was found in 90.5% of the patients. The median time until clinical improvement occurred was 5 [4/6] days. Daptomycin was well-tolerated and no major adverse events during therapy were observed observed. Conclusions This study provides new and helpful information regarding the beneficial use of daptomycin as supportive treatment option in patients developing mediastinitis after cardiac surgery.

    With a constantly growing population, water scarcity becomes the limiting factor for further social and economic growth. To achieve a partial reduction in current freshwater demands and lessen the environmental loadings, an increasing trend in the water market tends to adopt recycled water for household laundries as a new recycled water application. The installation of a small pre-treatment unit for water purification can not only further improve the recycled water quality, but also be viable to enhance the public confidence and acceptance level on recycled water consumption. Specifically, this paper describes column experiments conducted using a 550 mm length bed of zeolite media as a one-dimensional flow reactor. The results show that the zeolite filter system could be a simple low-cost pre-treatment option which is able to significantly reduce the total hardness level of recycled water via effective ion exchange. Additionally, depending on the quality of recycled water required by end users, a new by-pass controller using a three-level operation switching mechanism is introduced. This approach provides householders sufficient flexibility to respond to different levels of desired recycled water quality and increase the reliability of long-term system operation. These findings could be beneficial to the smooth implementation of new end uses and expansion of the potential recycled water market. The information could also offer sound suggestions for future research on sustainable water management and governance. PMID:24496024

    The discovery of the human immunodeficiency virus (HIV) as the causative organism of acquired immunodeficiency syndrome (AIDS) and the inability of modern medicine to find a cure for it has placed HIV as one of the most dreaded pathogens of the 21(st) century. With millions of people infected with HIV, it was once thought to result in "medical apocalypse". However, with the advent of antiretroviral therapy (ART), it is now possible to control HIV. Adherence to ART helps to keep the viral load under control and prolong the time of progression to AIDS, resulting in near normal life expectancy. Even with the introduction of ART, a substantial number of patients fail to adhere due to a variety of reasons, including adverse side effects, drug abuse, mental disorders, socioeconomic status, literacy, and social stigma. With the availability of so many options for HIV treatment at each stage of the disease progression, physicians can switch between the treatment regimens to avoid and/or minimize the adverse effects of drugs. Close monitoring, major social reforms, and adequate counselling should also be implemented to circumvent other challenges.

    2015-10-01

    Wastewater treatment plants at petroleum refineries often produce substantial quantities of sludge with relatively high concentrations of oil. Disposal of this waste is costly, in part because the high oil content requires use of secure disposal methods akin to handling of hazardous wastes. This article examines the properties of oily sludge and evaluates optional methods for reducing the oil content of this sludge to enable use of lower cost disposal methods. To reduce the oil content or break the structure of oily sludge, preliminary lab-scale experiments involving mechanical treatment, surfactant extraction, and oxidation are conducted. By applying surfactants, approximately 36% to 45% of oils are extracted from oily sludge. Of this, about 33% of oils are rapidly oxidised via radiation by an electron beam within 10 s of exposure. The Fenton reaction is effective for destruction of oily sludge. It is also found that 56% of oils were removed by reacting oily sludge with water containing ozone of 0.5 mg l(-1) over a period of 24 h. Oxidation using ozone thus can also be effectively used as a pretreatment for oily sludge. PMID:26261236

    Radiofrequency ablation (RFA) therapy is recognised as a safe and effective treatment option for osteoid osteoma. This case report describes a 27-year-old man who underwent computed tomography (CT)-guided percutaneous RFA for a femoral osteoid osteoma, which was diagnosed based on his clinical presentation and CT findings. The patient developed worsening symptoms complicated by osteomyelitis after the procedure. His clinical progression and subsequent MRI findings had led to a revised diagnosis of a Brodie's abscess, which was further supported by the eventual resolution of his symptoms following a combination of antibiotics treatment and surgical irrigations. This case report illustrates the unusual MRI features of osteomyelitis mimicking soft tissue tumours following RFA of a misdiagnosed Brodie's abscess and highlights the importance of a confirmatory histopathological diagnosis for an osteoid osteoma prior to treatment.

    Introduction Atrial fibrillation affects almost 2% of the population in the Western world. To preserve sinus rhythm, ablation is undertaken in symptomatic patients. Observational studies show that patients with atrial fibrillation often report a low quality of life and are less prone to be physically active due to fear of triggering fibrillation. Small trials indicate that exercise training has a positive effect on exercise capacity and mental health, and both patients with recurrent atrial fibrillation and in sinus rhythm may benefit from rehabilitation in managing life after ablation. No randomised trials have been published on cardiac rehabilitation for atrial fibrillation patients treated with ablation that includes exercise and psychoeducational components. Aim To test the effects of an integrated cardiac rehabilitation programme versus treatment as usual for patients with atrial fibrillation treated with ablation. Methods and analysis design The trial is a multicentre parallel arm design with 1:1 randomisation to the intervention and control group with blinded outcome assessment. 210 patients treated for atrial fibrillation with radiofrequency ablation will be included. The intervention consists of a rehabilitation programme including four psychoeducative consultations with a specially trained nurse and 12 weeks of individualised exercise training, plus the standard medical follow-up. Patients in the control group will receive the standard medical follow-up. The primary outcome measure is exercise capacity measured by the VO2 peak. The secondary outcome measure is self-rated mental health measured by the Short Form 36 questionnaire. Postintervention, qualitative interviews will be conducted in 10% of the intervention group. Ethics and dissemination The protocol is approved by the regional research ethics committee (number H-1-2011-135), the Danish Data Protection Agency (reg. nr. 2007-58-0015) and follows the latest version of the Declaration of Helsinki

  7. Therapeutic effectiveness and safety parathyroid adenoma ablation with percutaneous ethanol injection under sonographic guidance in patients with chronic renal failure and secondary hyperparathyroidism refractory to medical treatment

    International Nuclear Information System (INIS)

    Secondary hyperparathyroidism unresponsive to medical treatment is a common complication in patients with chronic renal failure and prolonged dialysis therapy, which requires surgery of the parathyroid glands, with the risks and costs of surgery. Objective: To evaluate the therapeutic effectiveness and safety of ablation of parathyroid adenomas by percutaneous ethanol injection under ultrasound guidance. Method: After approval by the institutional medical ethics committee, informed written consent was obtained in 15 patients who met the inclusion criteria. Sonographically guided ethanol was injected consecutively into adenomas, with an interval of time less than six months. Results: Size, Doppler vascularity of adenomas, and the levels of parathyroid hormone, calcium and phosphorus were measured before and after ablation as criteria for treatment response in 15 patients. Of all patients, six (40%) had no therapeutic response. Therapeutic response was observed in nine patients (60%). In the latter group, five patients (33.3%) had successful response and symptomatic improvement, in two patients (13.3%), therapeutic response was suboptimal, and in two patients (13.3%), the response was unsatisfactory. The procedure was safe. Local pain, transient dysphonia and cough were considered minor complications and were the most common, with resolution in all cases. There were no major complications. Conclusion: Ablation of parathyroid adenomas with percutaneous ethanol injection and ultrasound guidance, in uremic patients with secondary hyperparathyroidism unresponsive to medical treatment is an effective and safe therapy. Studies involving more patients and longer follow up are needed in order to stablish more conclusive results

    Abdominal aortic aneurysm is a common vascular disease that affects elderly population.Open surgical repair is regarded as the gold standard technique for treatment of abdominal aortic aneurysm,however,endovaseular aneurysm repair has rapidly expanded since its first introduction in 1990s.As a less invasive technique,endovascular aneurysm repair has been confirmed to be an effective alternative to open surgical repair,especially in patients with co-morbid conditions.Computed tomography (CT) angiography is currently the preferred imaging modality for both preoperative planning and post-operative follow-up.2D CT images are complemented by a number of 3D reconstructions which enhance the diagnostic applications of CT angiography in both planning and follow-up of endovascular repair.CT has the disadvantage of high cummulative radiation dose,of particular concern in younger patients,since patients require regular imaging follow-ups after endovascular repair,thus,exposing patients to repeated radiation exposure for life.There is a trend to change from CT to ultrasound surveillance of endovascular aneurysm repair.Medical image visualizations demonstrate excellent morphological assessment of aneurysm and stent-grafts,but fail to provide hemodynamic changes caused by the complex stent-graft device that is implanted into the aorta.This article reviews the treatment options of abdominal aortic aneurysm,various image visualization tools,and follow-up procedures with use of different modalities including both imaging and computational fluid dynamics methods.Future directions to improve treatment outcomes in the follow-up of endovascular aneurysm repair are outlined.

  9. Raynaud's phenomenon and digital ischaemia--pharmacologic approach and alternative treatment options.

    Linnemann, Birgit; Erbe, Matthias

    2016-01-01

    The primary goal of therapy is to reduce the frequency and intensity of Raynaud's attacks and to minimize the related morbidity rather than to cure the underlying condition. Treatment strategies depend on whether Raynaud's phenomenon (RP) is primary or secondary. All patients should be instructed about general measures to maintain body warmth and to avoid triggers of RP attacks. Pharmacologic intervention can be useful for patients with severe and frequent RP episodes that impair the patient's quality of life. Calcium channel blockers are currently the most prescribed and studied medications for this purpose. There has been limited evidence for the efficacy of alpha-1-adrenergic receptor antagonists, angiotensin receptor blockers, topical nitrates or fluoxetine to treat RP. The intravenously administered prostacyclin analogue iloprost can reduce the frequency and severity of RP attacks and is considered a second-line therapy in patients with markedly impaired quality of life, critical digital ischaemia and skin ulcers who are at risk for substantial tissue loss and amputation. Phosphodiesterase inhibitors (e.g., sildenafil) can also improve RP symptoms and ulcer healing whereas endothelin-1 receptor antagonists (e.g., bosentan) are mainly considered treatment options in secondary prevention for patients with digital skin ulcers related to systemic sclerosis. However, their use in clinical practice has been limited by their high cost. Antiplatelet therapy with low-dose aspirin is recommended for all patients who suffer from secondary RP due to ischaemia caused by structural vessel damage. Anticoagulant therapy can be considered during the acute phase of digital ischaemia in patients with suspected vascular occlusive disease attributed to the occurrence of new thromboses. In patients with critical digital ischaemia, consideration should be given to hospitalisation, optimisation of medical treatment in accordance with the underlying disease and evaluation for a

  10. Locoregional Treatment for Breast Carcinoma After Hodgkin's Lymphoma: The Breast Conservation Option

    International Nuclear Information System (INIS)

    Purpose: To report clinical and pathologic characteristics and outcome of breast cancer (BC) after irradiation for Hodgkin’s lymphoma (HL) in women treated at the Institut Curie, with a special focus on the breast-conserving option. Methods and Materials: Medical records of 72 women who developed either ductal carcinoma in situ or Stage I–III invasive carcinoma of the breast after HL between 1978 and 2009 were retrospectively reviewed. Results: Median age at HL diagnosis was 23 years (range, 14–53 years). Median total dose received by the mediastinum was 40 Gy, mostly by a mantle-field technique. Breast cancers occurred after a median interval of 21 years (range, 5–40 years). Ductal invasive carcinoma and ductal carcinoma in situ represented, respectively, 51 cases (71%) and 14 cases (19%). Invasive BCs consisted of 47 cT0–2 tumors (82%), 5 cN1–3 tumors (9%), and 20 Grade 3 tumors (35%). Locoregional treatment for BCs consisted of mastectomy with (3) or without (36) radiotherapy in 39 patients and lumpectomy with (30) or without (2) adjuvant radiotherapy in 32 patients. The isocentric lateral decubitus radiation technique was used in 17 patients after breast-conserving surgery (57%). With a median follow-up of 7 years, 5-year overall survival rate and locoregional control rate were, respectively, 74.5% (95% confidence interval [CI], 64–88%) and 82% (95% CI, 72–93%) for invasive carcinoma and 100% (95% CI, 100 –100%) and 92% (95% CI, 79–100%) for in situ carcinoma. In patients with invasive tumors, the 5-year distant disease-free survival rate was 79% (95% CI, 69–91%), and 13 patients died of progressive BC. Contralateral BC was diagnosed in 10 patients (14%). Conclusions: Breast-conserving treatment can be an option for BCs that occur after HL, despite prior thoracic irradiation. It should consist of lumpectomy and adjuvant breast radiotherapy with use of adequate techniques, such as the lateral decubitus isocentric position, to protect the

    The long-term outcomes of ultrasound-guided high-intensity focused ultrasound (USgHIFU) ablation treatment for adenomyosis and the relevant factors affecting the durability of symptom relief were assessed in this study.A total of 230 women with adenomyosis who were treated with USgHIFU ablation between January 2007 and December 2013 were retrospectively analyzed. The contrast-enhanced ultrasonography (CEUS) was performed immediately after the treatment to evaluate the ablation effect, and the nonperfused volume (NPV) ratio was then calculated. Regular follow-up was conducted and the visual analog scale (VAS) score was used to assess the changes in dysmenorrhea. The effect of treatment was evaluated after an average follow-up length of 3 months and the factors affecting clinical success and symptom relapse were identified.Of the 230 treated patients, 208 (90.4%) were followed up regularly, with a median follow-up length of 40 months (range, 18-94 months). Mean value of the NPV ratio calculated immediately after the treatment was 57.4 ± 24.4%. Varying degrees of symptomatic relief of dysmenorrhea based on the VAS scores were observed in 173 (83.2%) patients and 71.0% of the patients were asymptomatic during follow-up. Women with higher NPV ratio (OR = 0.964, 95% CI = 0.947-0.982, P = 0.000) and older age (OR = 0.342, 95% CI = 0.143-0.819, P = 0.016) were more likely to achieve clinical success. Dysmenorrhea recurred in 45 (26%) out of 173 cases; the median recurrence time was 12 months after treatment. The lower BMI (OR = 1.221, 95% CI = 1.079-1.381, P = 0.001) and the higher acoustic power (OR = 0.992, 95% CI = 0.986-0.998, P = 0.007) were associated with less risk of relapse. Twelve of the 14 patients who were retreated by USgHIFU ablation after experiencing dysmenorrhea recurrence achieved clinical success.USgHIFU ablation is an effective uterus-conserving treatment for symptomatic adenomyosis with an acceptable

    This report evaluates alternatives for pumping, storing, treating and disposing of the separable phase organic layer in Hanford Site Tank 241-C-103. The report provides safety and technology based preferences and recommendations. Two major options and several varations of these options were identified. The major options were: 1) transfer both the organic and pumpable aqueous layers to a double-shell tank as part of interim stabilization using existing salt well pumping equipment or 2) skim the organic to an above ground before interim stabilization of Tank 241-C-103. Other options to remove the organic were considered but rejected following preliminary evaluation.

    Pulmonary metastases are common in patients with cancer for which surgery is considered a standard approach in appropriately selected patients. A number of patients are not candidates for surgery due to a medical comorbidities or the extent of surgery required. For these patients, noninvasive or minimally invasive approaches to ablate pulmonary metastases are potential treatment strategies. This article summarizes the rationale and outcomes for non-surgical treatment approaches, including radiotherapy, radiofrequency and microwave ablation, for pulmonary metastases.

    Ochronosis is a rare disease characterised clinically by bluish-grey skin discolouration and histologically by yellow-brown pigment deposits in the dermis. It occurs in endogenous and exogenous forms. Endogenous ochronosis, also known as alkaptonuria, is an autosomal recessive disease of tyrosine metabolism, resulting in the accumulation and deposition of homogentisic acid in connective tissue. We report a case of facial endogenous ochronosis and coexistent photodamage, which was successfully treated with erbium-doped yttrium aluminium garnet laser resurfacing and deep focal point treatment to remove areas of residual deep pigment.

    This study quantified the interplay and gradient effects on GTV dose coverage for 3D CRT, dMLC IMRT, and VMAT SABR treatments for target amplitudes of 5-30 mm using 3DVH v3.1 software incorporating 4D Respiratory MotionSim (4D RMS) module. For clinically relevant motion periods (5 s), the interplay effect was small, with deviations in the minimum dose covering the target volume (D99%) of less than ± 2.5% for target amplitudes up to 30 mm. Increasing the period to 60 s resulted in interplay effects of up to ± 15.0% on target D99% dose coverage. The gradient effect introduced by target motion resulted in deviations of up to ± 3.5% in D99% target dose coverage. VMAT treatments showed the largest deviation in dose metrics, which was attributed to the long delivery times in comparison to dMLC IMRT. Retrospective patient analysis indicated minimal interplay and gradient effects for patients treated with dMLC IMRT at the NCCI. PMID:26894347

    Myelofibrosis with myeloid metaplasia (MMM) is currently classified as a classic (i.e. not yet molecularly defined) myeloproliferative disorder (MPD), along with essential thrombocythemia (ET) and polycythemia vera (PV). All three MPDs represent stem-cell-derived clonal myeloproliferation that, in the case of MMM, is accompanied by an intense bone marrow stromal reaction that includes collagen fibrosis, osteosclerosis, and angiogenesis. To date, both the molecular basis of the primary clonal process and the pathogenetic mechanisms that underlie the secondary histological changes remain elusive. Clinically, MMM is characterized by anemia, multi-organ extramedullary hematopoiesis that often involves the spleen and liver, constitutional symptoms, and premature death from either leukemic transformation or other disease complications. Current diagnosis is based on characteristic but not diagnostic bone marrow histological features. Modern therapy remains palliative but allogeneic stem cell transplantation might be curative to a selected group of patients. This chapter reviews both the old and the new therapy with regard to non-transplant treatment options for MMM.

    We present a case of ventricular storm (VS) in a patient with acute ST-elevation myocardial infarction (STEMI). After initial successful thrombus extraction and percutaneous coronary intervention (PCI) of the proximal left anterior descending (LAD) coronary artery, a 63-year-old male patient showed recurrent monomorphic ventricular tachycardia (VT) and fibrillation (VF) episodes refractory to antiarrhythmic drug therapy. After initial successful VT ablation, fast VT and VF episodes remained an evident problem despite maximum antiarrhythmic drug therapy. Due to an increasing instability, renal sympathetic denervation (RDN) was performed. ICD interrogation and 24-hour Holter monitoring excluded recurrent episodes of VT or VF at a 6-month follow-up (FU) after discharge. This case highlights that RDN was effective and safely performed in a hemodynamically unstable patient with VS after STEMI and adjunct catheter ablation. RDN may open a new avenue for an adjunctive interventional bailout treatment of such highly challenging patients.

    Low-density lipoprotein cholesterol (LDL-C) is currently the primary target in the management of dyslipidemia, and statins are first-line pharmacologic interventions. Adjunct therapy such as niacins, fibrates, bile acid sequestrants, or cholesterol absorption inhibitors may be considered to help reduce cardiovascular risk. This review discusses the need for alternative adjunct treatment options and the potential place for omega-3 fatty acids as such. The cardiovascular benefits of fish consumption are attributed to the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and a variety of omega-3 fatty acid products are available with varied amounts of EPA and DHA. The product types include prescription drugs, food supplements, and medical foods sourced from fish, krill, algal and plant oils or purified from these oils. Two prescription omega-3 fatty acids are currently available, omega-3 fatty acid ethyl esters (contains both EPA and DHA ethyl esters), and icosapent ethyl (IPE; contains high-purity EPA ethyl ester). A pharmaceutical containing free fatty acid forms of omega-3 is currently in development. Omega-3 fatty acid formulations containing EPA and DHA have been shown to increase LDL-C levels while IPE has been shown to lower triglyceride levels without raising LDL-C levels, alone or in combination with statin therapy. In addition, recent studies have not been able to demonstrate reduced cardiovascular risk following treatment with fibrates, niacins, cholesterol absorption inhibitors, or omega-3 fatty acid formulations containing both EPA and DHA in statin-treated patients; thus, there remains a need for further cardiovascular outcomes studies for adjunct therapy.
