    Benign pancreatic tumors should undergo surgical resection when they are symptomatic or - in the case of incidental discovery - bear malignant potential. This is the case for the majority of benign pancreatic tumors, especially for intraductal papillary mucinous neoplasms or mucinous cystic adenomas. In addition, resection is indicated for all tumors where preoperative diagnostic fails to provide an exact classification. Several different operative techniques are available. The treatment of choice depends on the localization of the tumor, its size and on whether there is evidence of malignant transformation. Partial duodenopancreatectomy is the oncological treatment of choice for tumors of the pancreatic head whereas for tumors of the pancreatic tail a left-sided pancreatectomy is appropriate. Middle pancreatectomy or duodenum-preserving resection of the pancreatic head is not a radical oncologic procedure. They should only be performed in cases of tumors without malignant potential. (orig.) [German] Die Indikationsstellung zur Resektion benigner Pankreastumoren ist gegeben, wenn es sich um einen symptomatischen Tumor handelt oder - bei einem Zufallsbefund - um einen Tumor mit Potenzial zur malignen Entartung. Dies besteht bei der Mehrzahl der benignen Pankreastumoren, insbesondere bei der intraduktalen papillaeren muzinoesen Neoplasie (IPMN) oder muzinoesen Zystadenomen. Operativer Abklaerung beduerfen auch Tumoren, die unter Ausschoepfung aller diagnostischer Moeglichkeiten nicht eindeutig klassifizierbar sind. An chirurgischen Therapieverfahren stehen verschiedene Techniken zur Verfuegung. Die Wahl des Verfahren haengt von der Groesse und Lokalisation des Tumors ab und von der Frage, ob eine maligne Entartung bereits stattgefunden hat. Das onkologisch korrekte Standardresektionsverfahren bei Tumoren des Pankreaskopfes ist die partielle Duodenopankreatektomie, bei Tumoren des Pankreasschwanzes die Pankreaslinksresektion.

    Computed tomography (CT) and in particular multi-detector row computed tomography (MDCT), also known as multislice CT (MSCT), is ideally suited for detecting pancreatic tumors because of the high spatial resolution. The method of choice is hydro-CT which involves distension of the stomach and duodenum by administration of 1-1.5 l water as a negative contrast medium under medically induced hypotension by administration of buscopan. The patient is laid on the right side at an angle of 30-45 in order to obtain an artefact-free image of the close anatomical relationship around the pancreas head. In addition, curved MPRs or in rare cases 3D reconstructions could be very helpful in identifying the critical anatomic tumor site in the neighbourhood of the visceral vessel system. After the correct diagnosis of an adenocarcinoma has been made only 20% of all patients are shown to have a surgically resectable disease, but the overall survival rate is significantly higher after resection in combination with a multimodal tumor therapy strategy. The reason is that the correct diagnosis of the resectability of the tumor is one of the main criteria for overall survival of these patients. Currently practically all pancreatic tumors can be detected using MDCT and the detection rate varies between 70% and 100% (most recent literature references give a sensitivity of 89% and specificity up to 99%). In some rare cases the differentiation between focal necrotizing pancreatitis and pancreatic carcinoma can be difficult even with sophisticated protocols. Resectability can be correctly diagnosed with MDCT with a sensitivity of 94% and a specificity of 89%. MDCT is an ideal tool for the detection of neuroendocrine tumors, metastases and for the differentiation of cystic pancreatic lesions such as pseudocysts, microcystic adenomas or intraductal papillary mucinous neoplasms (IPMN). Particularly, the differentiation of the latter into benign, borderline or malignant transformation is not

Some indications are clearly identified as treatment of arteriovenous malformations (AVM), hyperthyroid ophthalmopathy, postoperative heterotopic bone formations or keloid scars. Some indications are under evaluation as complications induced by neo-vessels of age-related macular degeneration or coronary restenosis after angioplasty. Some indications remain controversial with poor evidence of efficiency as treatment of bursitis, tendinitis or Dupuytren's disease. Some indications are now obsolete such as warts, or contra-indicated as treatment of infant and children. (authors)

    X-ray should only be applied when other forms of treatment of good-natured diseases do not provide equally good results. One should note that somatic lesion should be completely avoided and genetic lesion avoided to the greatest probability. One can distinguish according to ones aims between inflammation irradiation, pain irradiation, stimulation therapy and functional therapy. An indication for inflammation irradiation can be post-operative parotitis, furuncle in the face, mastitis puerperalis, panaritium ossale, recurrent sudoriparouns abscesses and repelling reactions after transplanting organs. Pain irradiation is indicated with degenerative diseases of the skeleton system. A further possible application is radiotherapy of hypotrophic processes and benign tumours. Functional radiotherapy is indicated with hyperendocrinism, neurovegetative disorders and allergies. (MG) [de

    Cases of radiation therapy for benign diseases have diminished in number because of recent alternative methods and knowledge about radiation carcinogenesis. In contrast to this tendency, our cases of benign diseases have recently increased. The facts made us reconsider today's radiation therapy of benign diseases. We reviewed 349 patients who were diagnosed as having benign tumors or non-neoplastic conditions and treated by radiation therapy in the past sixteen years. Analyzed items were the annual transition of treatment number, sorts of diseases, patients' age and sex, and the goal of therapy. Of all radiation therapy patients, benign diseases account for 9.26%. The annual percentages were 0.5%, 6.0%, 11.2% and 13.7% at intervals of five years since 1982. The majority was 246 post-operative irradiation for keloids (71%) and 41 pituitary adenomas (12%). Compared with malignant tumors, benign disease patients were statistically younger and female-dominant. Applications of radiation therapy in keloids and pituitary adenomas had definite goals, but were unclear in other rare diseases. Benign diseases should be treated by radiation therapy as the second or third option, provided the patients have serious symptoms and their diseases do not respond to other modalities. It seems to be widely accepted that favorite cases such as keloids and pituitary adenomas are treated by radiation therapy. But, optimal radiation therapies for other rare benign diseases have not been established. Therefore, the building of databases on radiation therapy on benign diseases should be pursued. Since benign disease patients were young and female-dominant and had many remaining years, their carcinogenicity potential should be considered. (author)

It seems clear that no single factor reliably predicts the outcome...... of an exact thyroid dose is error-prone due to imprecise measurement of the (131)I biokinetics, and the importance of internal dosimetric factors, such as the thyroid follicle size, is probably underestimated.

    Full Text Available Background: The purpose of observational program of patients with lower urinary tract symptoms (LUTS because of benign prostatic hyperplasia (BPH (LUTS/BPH was to acquire additional pharmaco-epidemiological data on the safety and efficacy of combination therapy with finasteride and tamsulosin.Methods: Observational program of men with BPH was conducted in urological outpatient clinics in Slovenia from April 2004 until November 2005. In open-label, non-interventional program 1173 patients were observed, who had been treated because of LUTS/BPH with combination therapy with finasteride and tamsulosin, in the framework of common treatment. At baseline and after six months of treatment for each patient the International Prostatic Symptom Score (IPSS questionnaire and assessment of quality of life (QL were filled in. In addition, urinary flow rate and prostate volume were determined. Adverse effects of drugs were reported spontaneously. For statistical analysis the Student’s t-test was performed.Results: Combination therapy with finasteride and tamsulosin was well tolerated. 89 (7.6 % patients discontinued with medication because of lack of efficacy or because of adverse effects of drugs. Symptom score, assessment of quality of patients’ lives and volume of prostates were significantly lower (p < 0.0001, while urinary flow rate was significantly higher (p < 0.0001 after six months of treatment with finasteride and tamsulosin.Conclusions: Combination therapy of patients with LUTS/BPH with finasteride and tamsulosin is effective and safe.

    The version 3 of the guideline for radioiodine therapy for benign thyroid diseases presents first of all a revision of the version 2. The chapter indication for radioiodine therapy, surgical treatment or antithyroid drugs bases on an interdisciplinary consensus. The manifold criteria for decision making consider the entity of thyroid disease (autonomy, Graves' disease, goitre, goitre recurrence), the thyroid volume, suspicion of malignancy, cystic nodules, risk of surgery and co-morbidity, history of subtotal thyroidectomy, persistent or recurrent thyrotoxicosis caused by Graves' disease including known risk factors for relapse, compression of the trachea caused by goitre, requirement of direct therapeutic effect as well as the patient's preference. Because often some of these criteria are relevant, the guideline offers the necessary flexibility for individual decisions. Further topics are patients' preparation, counseling, dosage concepts, procedural details, results, side effects and follow-up care. The prophylactic use of glucocorticoids during radioiodine therapy in patients without preexisting ophthalmopathy as well as dosage and duration of glucocorticoid medication in patients with preexisting ophthalmopathy need to be clarified in further studies. The pragmatic recommendations for the combined use of radioiodine and glucocorticoids remained unchanged in the 3{sup rd} version. (orig.)

    Ductal adenocarcinoma is the most common malignant tumor of the pancreas. Despite great efforts in basic and clinical pancreatic cancer research, the prognosis remains poor with an overall 5-year survival rate of less than 5%. Complete surgical resection represents the only curative treatment option and 5-year survival rates of 20-25% can be achieved following curative resection and adjuvant chemotherapy. Although pancreatic surgery is considered one of the most technically demanding and challenging procedures, there has been constant progress in surgical techniques and advances in perioperative care with a modern interdisciplinary approach including anesthesiology, oncology, radiology and nursing. This has reduced morbidity and especially mortality rates in high-volume centers. Among extended resection procedures multivisceral and venous resections are technically feasible and should be considered if a complete tumor resection can be achieved. Multimodal regimens have shown promising results, however, only adjuvant chemotherapy is supported by solid evidence from randomized controlled trials. (orig.) [German] Das duktale Adenokarzinom ist der haeufigste maligne Pankreastumor. Trotz intensiver Anstrengungen auf dem Gebiet der Pankreasforschung konnte die Gesamtprognose in den vergangenen Jahren nicht entscheidend verbessert werden. Die einzige potenziell kurative Therapie ist die chirurgische Resektion. In Kombination mit einer adjuvanten Chemotherapie liegen die 5-Jahres-Ueberlebensraten aktuell bei 20-25%. Dank kontinuierlicher Weiterentwicklung der chirurgischen Operationstechnik und Verbesserungen der perioperativen Versorgung der Patienten mit einer engen interdisziplinaeren Zusammenarbeit (Chirurgie, Anaesthesie, Onkologie, Radiologie und Pflege) konnten die perioperative Morbiditaets- und Mortalitaetsraten in den vergangenen Jahren deutlich gesenkt werden.

    2011-01-01

    The activity to be administered in I-131 therapy of benign thyroid disease is determined by the radiation absorbed dose necessary to cure the disease, the target mass, and the residence time of the I-131 in the target volume. Data from 73 patients with complete sets of uptake measurements 2, 6, 24, 48, and 96 (n = 53) or 120 (n = 20) hours after oral administration of 1 MBq I-131 were used to deduce residence times from subsets of 3, 2, or only 1 measurement for each individual. The values were compared to those obtained with the reference method, i.e. a fit of an uptake function based on a 2-compartment model to all 5 measurements, to quantify the errors introduced by the less demanding assessments. Deviations are less than 10% if the 2- compartment uptake function is fitted to only 3 values measured after 6, 24, and 96-120 h. Use of 2, 24, and 96-120 h data results in errors > 20% in individual patients. The effective half-lives as determined from 2 measurements after 24 and 96-120 h correlate well with those deduced from the reference method with larger deviations in individuals with slow iodine kinetics and late maximal uptake. Residence times determined from the 24 h uptake, assuming linear increase during the first day, and the effective half-life limited to maximum 8 days underestimate the actual values systematically in patients with long and short half-lives. These errors can be eliminated by a modification of the calculation method resulting in deviations less than 14% in all but one individual for this procedure. The accuracy of methods based on only one retention value increases with the time of measurement after the administration of I-131. While systematic errors up to a factor of two occur if the 24 h uptake is used for the estimate, deviations are less than 18% for measurements after 120 h. The results suggest that only one late uptake assessment warrants residence time estimates with an acceptable error. Given the high inherent uncertainties in the

    Full Text Available Benign prostatic hypertrophy (BPH has become a major global health problem both in its frequency by which it determines the complications and the problems of diagnosis and treatment it requires. BPH is a heterogeneous disease. The symptoms attributed to BPH may have other coexisting causes and growth factors both androgen-dependent and independent, which promotes prostate enlargement. It is well known that prostate size correlates poorly with the symptoms so that reducing prostate using 5-alphareductase or alphablocants inhibitors may not always be sufficient. A better understanding of the pathophysiology of BPH and its interactions with other drugs will help the development of new substances with a better efficiency. This present work aims to be a modest contribution related to medical treatment in benign prostatic hyperplasia and the role that the generalist practitioner should play in managing of this urinary disease quite common in elderly men.

  7. Radioiodine therapy of benign thyroid disorders: functional thyroid autonomy

    International Nuclear Information System (INIS)

    2005-01-01

    In the last 15 years, several concepts have been developed to further improve the outcome of radioiodine therapy in functional thyroid autonomy. Results of radioiodine therapy in functional autonomy are considerably better than in Graves' disease. All of the currently-applied concepts offer healing rates of 75-100%, but they differ considerably in the hypothyreosis rates attained. The target volume can be precisely determined by sonography only in unifocal autonomy. In the case of multifocal and disseminated autonomy, the entire thyroid is taken as the target volume and the focal dose is reduced ('dosimetric compromise'). TcTUs-based dose concepts calculate the functionally autonomous volume from the TcTUs and replace the target volume by sonography, in the TcTUs-adapted dose concepts, sonographic target volume is left and the focal dose varied in dependence of the suppression uptake. The objective is to attain a high rate of success with a low rate of hypothyreosis. (orig.)

    Purpose: To investigate the long-term outcome of stereotactic-based radiation therapy in a large cohort of patients with benign intracranial meningiomas. Methods and Materials: Between 1997 and 2010, 318 patients with histologically confirmed (44.7%; previous surgery) or imaging-defined (55.3%) benign meningiomas were treated with either fractionated stereotactic radiation therapy (79.6%), hypofractionated stereotactic radiation therapy (15.4%), or stereotactic radiosurgery (5.0%), depending on tumor size and location. Local control (LC), overall survival (OS), cause-specific survival (CSS), prognostic factors, and toxicity were analyzed. Results: The median follow-up was 50 months (range, 12-167 months). Local control, OS, and CSS at 5 years were 92.9%, 88.7%, and 97.2%, and at 10 years they were 87.5%, 74.1%, and 97.2%, respectively. In the multivariate analysis, tumor location (P=.029) and age >66 years (P=.031) were predictors of LC and OS, respectively. Worsening of pre-existing neurologic symptoms immediately after radiation therapy occurred in up to 2%. Clinically significant acute toxicity (grade 3°) occurred in 3%. Only grade 1-2 late toxicity was observed in 12%, whereas no new neurologic deficits or treatment-related mortality were encountered. Conclusions: Patients with benign meningiomas predominantly treated with standard fractionated stereotactic radiation therapy with narrow margins enjoy excellent LC and CSS, with minimal long-term morbidity.

    Spinal affections belong to the most widespread sources of back pain. Beside medical history and clinical examination, the radiological investigation plays an important rote in the clinical workup especially with the modern Cross sectional imaging methods such as computed and magnetic resonance tomography. After exclusion of a malignant disease usually a conservative therapeutic approach is the first line treatment option. If the conservative treatment approach falls a minimalinvasive image guided diagnostic or therapeutic infiltration may be considered. Thereby the interventional radiologist should be a member of the team which decides the clinical strategy. This article describes epidemiology and pathophysiology, common pre-interventional diagnostic strategies, drugs, indications, possible complications and the impact of diagnostic and therapeutic minimally invasive image guided techniques in low back pain. In this context facet joint blockade, periradicular and peridural therapy as well as sacroiliac joint blockades are discussed

    This study was designed to clarify the efficacy of combination of thyroid hormone (euthyrox) therapy and percutaneous ethanol injection (PEI) in benign nodular thyroid diseases. 55 patients with benign nodular goiter after the first PEI session during the whole study period (from 3 till 12 months after PEI) daily received euthyrox in a dosage - 50 mkg. 48 women and 7 men with thyroid nodules of the various sizes, structures and echogenecity have been included in the study group. The control group consisted of 32 patients: 29 women and 3 men in the same age range as in the study group. In both groups PEI procedure was performed but in the control group no thyroid hormone was added. In patients who were receiving 50 mkg daily after 3 months of PEI progressive reduction of the nodule sizes was registered, the volume of a thyroid gland has decreased and approached to normal parameters (15,79+/-1,21 ml), and in 6-2 months the normal volume of the thyroid gland was registered. Thus, combination of thyroid hormone therapy and percutaneous ethanol injection (PEI) in treatment of patients with benign nodular goiter normalizes the size of a thyroid gland. Euthyrox is the additional factor causing reduction of thyroid nodules and constraining occurrence of new nodules in a thyroid gland.

    Full text of publication follows. Aim: in the last years Peptide Receptor Radionuclide Therapy (PRRT) acquired greater importance as an alternative or complementary treatment of neuroendocrine tumors (NETs) and other somatostatin receptor positive (sstr+) tumors. Many studies about PRRT using different radiopharmaceuticals, mainly 90 Y and 177 Lu (beta-emitters) labelled peptides, are reported in the literature. 177 Lu-labeled somatostatin analogues seem to be more effective because of their favourable physical properties and the better objective response. On the other hand, only few reports exist on PRRT using 111 In-Pentetreotide, an Auger-emitter. The aim of this study is to evaluate the usefulness of 111 In-Pentetreotide therapy in patients with sstr+ inoperable benign intracranial tumors in which the use of beta-emitters radiopharmaceuticals (characterized by higher penetration range) could be unsafe and questionable since lesions were close to critical anatomical structures, such as optic chiasm or medulla oblongata. Materials and methods: we retrospectively reviewed clinical records of 9 patients (7 Females and 2 Males) affected by sstr+ benign intracranial tumors (mean age: 58.4 years, range 50-81): 8 patients had meningiomas/meningiomatosis and 1 patient had a pituitary macroadenomas. A previous diagnostic scintigraphy with 111 In-Pentetreotide demonstrated high intralesional radiotracer uptake. All patients underwent PRRT with high therapeutic activities of 111 In-Pentetreotide (1-7 cycles, median 4 cycles, activity per cycle 3.7-7.5 GBq, median activity per cycle 7 GBq, cumulative activity range 13.7-66 GBq). Efficacy of PRRT was evaluated according to RECIST criteria. Toxicity was also assessed considering hematological parameters and GFR value estimated by renal dynamic scintigraphy. Results: no patient had acute damage. Complete response was observed in 1 patient (11.1%). Partial response was observed in 2 patients (22.2%); stable disease was observed

    The results of preoperative preparation were analysed in 59 patients with prostatic benign hyperplasia (PBH) subjected to TUR. Treatment outcomes were assessed by transrectal ultrasound (color Doppler mapping) in two groups of patients. Group 1 received combined therapy including transrectal laser radiation of the prostate, group 2--transrectal magnetotherapy. The analysis showed that laser radiation reduced insignificantly the size of the prostate and adenomatous node, improved microcirculation and circulation in the prostate. This resulted in relief of inflammation and reduction of the number of postoperative inflammatory complications. Transrectal magnetotherapy has a positive effect on vascularization and hemodynamics of the prostate, local immunity, contamination of the tissues with pathogenic flora.

    The role of minimally invasive surgical therapies in the treatment of BPH is still yet to be strongly defined. Given the experimental nature of many of the modalities, further study is required prior to their recommendation as alternatives to invasive surgical therapy. More mature evidence is required for the analysis of durability of effect of these therapies to make robust conclusions of their effectiveness.

Improved results can be obtained by drug vectorization to the hyperplastic tissue. The main objective of this work was the preparation and characterization of poly(lactic-co-glycolic acid (PLGA nanoparticle and clay nanosystems containing babassu oil (BBS. BBS was extracted from the kernels of babassu tree nuts and characterized by gas chromatography-mass spectrometry as well as 1H and 13C nuclear magnetic resonance. BBS-clay nanosystems were obtained by adding polyvinylpyrrolidone, Viscogel B8®, and BBS at a 2:1:1 mass ratio and characterized by X-ray diffraction, thermogravimetric analysis, infrared spectroscopy, and laser diffraction. The PLGA-BBS nanoparticles were prepared by the precipitation-solvent evaporation method. Mean diameter, polydispersity, zeta potential, and scanning electron microscopic images of the nanosystems were analyzed. Thermogravimetric analysis showed successful formation of the nanocomposite. PLGA nanoparticles containing BBS were obtained, with a suitable size that was confirmed by scanning electron microscopy. Both nanostructured systems showed active incorporation yields exceeding 90%. The two systems obtained represent a new and potentially efficient therapy for benign prostatic hyperplasia.

    Dose planning prior to radioiodine therapy of benign thyroidal disease is usually based on macrodosimetry. The paper shows that this assumption is acceptable. The common concepts for dose planning are given. The following target doses are nowadays widely accepted: 150 Gy for euthyroid goiter, 400 Gy for toxic adenoma, 150 Gy for disserminated autonomy, 200 Gy for hyperthyroid Grave's disease if posttherapeutic euthyroidism is intended, and 250 (to 300) Gy if the risk of recurrency is to be minimized ('ablative' concept). Finally, a surveyfis given concerning the precision in which the parameters relevant for the dose calcultion can be determined. For realistic favourable conditions, the dose can be determined with an accuracy of better than ±25%. (orig.) [de

    Background: Radiotherapy of benign diseases is controversial and rarely applied in Anglo-American countries, whereas in other parts of the world it is commonly practiced for several benign disorders. Similar to a European survey, a pattern of care study was conducted in Germany. Method: Using a mailed questionnaire, radiation equipment, treatment indication, number of patients, and treatment concepts were assessed in 1994, 1995, and 1996 in 134 of 152 German institutions (88%): 22 in East and 112 in West Germany; 30 in university hospitals and 104 in community hospitals. Average numbers of each institution and of all institutions were analyzed for frequencies and ratios between regions and among institutions. Radiation treatment concepts were analyzed. Results: A mean of 2 (range 1-7) megavoltage and 1.4 (range 0-4) orthovoltage units were available per institution; 32 institutions (24%) had no orthovoltage equipment. A mean of 20,082 patients were treated annually: 456 (2%) for inflammatory diseases (221 hidradenitis, 78 local infection, 23 parotitis; 134 not specified) 12,600 (63%) for degenerative diseases (2711 peritendinitis humeroscapularis, 1555 epicondylitis humeri; 1382 plantar/dorsal heel spur; 2434 degenerative osteoarthritis; 4518 not specified); 927 (5%) for hyperproliferative diseases (146 Dupuytren's contracture, 382 keloids; 155 Peyronie's disease; 244 not specified); 1210 (6%) for functional disorders (853 Graves' orbitopathy; 357 not specified); and 4889 (24%) for other disorders (e.g., 3680 heterotopic ossification prophylaxis). In univariate analysis, there were geographic (West vs. East Germany) differences in using radiation therapy (RT) for inflammatory and degenerative disorders, and institutional differences (university versus community hospitals) in using RT for hyperproliferative and functional disorders (p < 0.05). The prescribed dose concepts were mostly in the low dose range, <10 Gy but varied widely and inconsistently within

    Full Text Available Introduction. Benign prostatic hyperplasia (BPH causes disorders of voiding and sexual function. Pharmacologic therapy reduces symptoms of voiding thus impacting sexual function. Objective. To determine sex life status in men with BPH before and after pharmacologic treatment adapted to achieve satisfactory sexual function. Methods. We studied 117 sexually active BPH patients, not previously treated for BPH. After clinical examinations, symptoms of voiding, sexual and ejaculatory function were measured using standardized IPSS, IIEF and MSHQ-EjD questionnaires. After obtaining patients’ personal opinion about the importance of their sex life, therapy was chosen and possible side effects explained. Three groups of 39 patients each were formed. The first group was treated with alpha-blocker, tamsulosin, the second with 5-alpha reductase inhibitor, finasteride, while the third group was administered a combination therapy. The complete examination procedure was repeated after 3 and 6 months of therapy. Results. The average age of patients was 61.34±3.04 years. Eighty-seven percent reported that their sex life was important to a certain degree. Satisfaction with their sex life was reported by 47% of patients before treatment and by 67% of respondents 6 months after treatment. Questionnaire scores indicated general improvement of sexual function in all groups, which was statistically significant compared to baseline only in the group on tamsulosin alpha-blocker (2.95±7.81; p=0.028. The overall satisfaction with sex life as a component of sexual function, improved significantly in the group on the combined therapy (0.78±1.81; p=0.012. Conclusion. Before BPH treatment sexual function should be assessed and therapy customized to the patient’s expectations. Side effects of drugs should be presented especially to patients who emphasize the importance of sex life. In the manifested stages of the disease overall satisfaction with sex life may be

    Benign thyroid disease ranks by far as the most frequent therapy in nuclear medicine. In Germany approximately 25 000 cases of hyperthyreosis are being treated in association with autonomy or Graves` disease, but also for the reduction of goiters or the correction of latent functional disturbances. In such indications radiotherapy is virtually free of risk as opposed to surgery and ranks more favorable in regard to costs and curative effects versus pharmacological long term treatment. Still regional varying therapeutical concepts and intentions are being pursued and trials of improvements described. There is consent in therapy that quality of treatment is closely linked to a specialized out-door platient preparation, individual hospital activity dosage and lifelong follow up including continued evaluation of therapeutical results. In this paper minimal requirements of outpatient measures before and after therapy are summarized which in Germany is only permitted on an inhospital patient basis. Considering basics of radioactive preventive law, scientific evidence of available results of therapeutical studies and a survey of German therapeutic centers, suggestions for a quality maintaining management in view of the most effective utilization for the limited available number of beds is presented for discussion.

    The purposes of the current study were to test the feasibility of exercise therapy for children with benign epilepsy with centrotemporal spikes (BECTS) and to collect pilot data about the impact of exercise therapy on neurocognitive, emotional, and behavioral outcomes. Ten children with BECTS (9.7±1.42 years) participated in a therapeutic exercise program consisting of ten supervised exercise sessions and home-based exercises for five weeks. Electroencephalography (EEG), seizure frequency, and neurocognitive and psychological factors, including attention, executive function, depression, anxiety, behavioral problems, and quality of life, were assessed before and after the exercise program. No clinical symptoms were observed to worsen during the study, demonstrating that the exercise therapy was safe and also feasible. After five weeks of exercise therapy, significant improvements in neurocognitive domains such as simple visual and auditory attention, sustained attention, divided attention, psychomotor speed, and inhibition-disinhibition were observed. Furthermore, parent ratings of internalizing behavioral problems and social problems and mood-related well-being from quality of life improved after exercise therapy. Although not statistically significant, trends were noted toward improvement in children's self-reports of negative mood/somatization, parent reports of somatic complaints, and general health on a quality-of-life measure. A five-week structured exercise program was successfully implemented, with preliminary data suggesting beneficial impact on neurocognitive and psychobehavioral function. Exercise therapy should be further evaluated as a part of a comprehensive treatment program for children with benign epilepsy. Copyright © 2014 Elsevier Inc. All rights reserved.

    alternatives are needed. Until recently, levothyroxine therapy was the preferred non-surgical alternative, but due to low efficacy and potential side-effects, it is not recommended for routine use in recent international guidelines. Conventional radioiodine (131I)-therapy has been used for two decades......, which makes 131I-therapy less feasible. Another challenge is the negative correlation between initial goitre size and goitre volume reduction (GVR). With its ability to more than double the thyroid 131I-uptake, recombinant human TSH (rhTSH) increases the absorbed radiation dose and thus enhances the GVR...... efficacy. Thus, although in its infancy, and still experimental, rhTSH-augmented 131I-therapy may profoundly alter the nonsurgical treatment of benign non-toxic MNG....

  5. Impact of preventive therapy on the risk of breast cancer among women with benign breast disease.

    There are three main ways in which women can be identified as being at high risk of breast cancer i) family history of breast and/or ovarian cancer, which includes genetic factors ii) mammographically identified high breast density, and iii) certain types of benign breast disease. The last category is the least common, but in some ways the easiest one for which treatment can be offered, because these women have already entered into the treatment system. The highest risk is seen in women with lobular carcinoma in situ (LCIS), but this is very rare. More common is atypical hyperplasia (AH), which carries a 4-5-fold risk of breast cancer as compared to general population. Even more common is hyperplasia of the usual type and carries a roughly two-fold increased risk. Women with aspirated cysts are also at increased risk of subsequent breast cancer. Tamoxifen has been shown to be particularly effective in preventing subsequent breast cancer in women with AH, with a more than 70% reduction in the P1 trial and a 60% reduction in IBIS-I. The aromatase inhibitors (AIs) also are highly effective for AH and LCIS. There are no published data on the effectiveness of tamoxifen or the AIs for breast cancer prevention in women with hyperplasia of the usual type, or for women with aspirated cysts. Improving diagnostic consistency, breast cancer risk prediction and education of physicians and patients regarding therapeutic prevention in women with benign breast disease may strengthen breast cancer prevention efforts.

    2002-09-01

    5 alpha-reductase inhibitors and alpha 1-receptor blockers are the two main drug therapies used in the management of symptomatic benign prostatic hyperplasia. As alpha-reductase inhibitors and alpha 1-receptor blockers act through different mechanisms, a combination of the two agents might be promising. The potential benefits of combination therapy with selective alpha 1-receptor blockers and finasteride, a 5 alpha-reductase inhibitor, are currently being evaluated in several placebo-controlled prospective multicenter studies (VA Study, ALFIN Study, PREDICT Study, and MTOPS Study). The data from these studies available so far demonstrate a statistically significant benefit for the study groups receiving alpha 1-receptor blockers and combination therapy vs placebo and finasteride monotherapy in terms of symptom scores and peak urine flow rates. However, none of the studies yielded a statistically significant advantage of combination therapy over treatment with alpha 1-receptor blockers. These results should be interpreted with reference to the prostatic volume, which in the studies mentioned above was relatively low. From the results of all these studies, it can be concluded that in symptomatic patients with prostate volumes of up to 40-45 ml a combination of 5 alpha-reductase inhibitors with alpha 1-receptor blockers does not appear to provide any benefit. Yet, it can be assumed that in symptomatic patients with prostate volumes of more than 60 ml combination therapy may indeed prove more effective.

    To determine the importance of accurate topological diagnostics of the otolith and the differentiation of certain clinical forms of benign paroxysmal positional vertigo (BPPV). A prospective study was conducted at the County General Hospital Vukovar in the period from January 2011 till January 2012. A total of 81 patients with BPPV, 59 females (72.84%) and 22 (27.16%) males (p less than 0.001), mean age 60.1 (± 12.1) were examined. The diagnosis was confirmed and documented by videonystagmography (VNG). The disability due to disease and risk of falling were monitored by filling in the Dizziness Handicap Inventory (DHI) and Activities-specific Balance Confidence Scale (ABC) questionnaires at the beginning and at the end of the repositioning treatment. In 79 (97.3%) patients posterior semicircular canal was affected, and in a small number of patients, two (2.47%) the lateral one. After the repositioning procedures were performed, there was a significant reduction or complete elimination of symptoms in the majority of subjects, 76 (93.82%). The median total DHI sum amounted to 50.5 (± 22.2) at the beginning and 20.4 (± 18.5) at the end of the study (p less than 0.00). Similarly, the results of ABC questionnaires at the beginning of the study demonstrated a result of 59.2% (± 22.4%), and at the end of the treatment the average result of examinees was significantly higher, 84.9% (± 15.2%) (p less than 0.00). Although a subjectively positive Dix-Hallpike or a "supine roll" test is sufficient for the diagnosis of BPPV, it is necessary perform the VNG as well in order to precisely determine the exact localization of the otolith, so that an appropriate repositioning procedure can be applied.

    Objective To conduct a cost-effectiveness analysis from payers’ perspectives of six treatments for lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH) and to examine positioning of these modalities in the marketplace for the best use of health care funds and quality-of-life benefits for patients. Methods The economic analysis was conducted with a Markov model to compare combination prescription drug therapy (ComboRx), minimally invasive therapies (MITs) including convective radiofrequency (RF) water vapor thermal therapy (Rezūm®), conductive RF thermal therapy (Prostiva®), and prostatic urethral lift (UroLift®), and invasive surgical procedures including photovaporization of the prostate (Greenlight® PVP) and transurethral resection of the prostate (TURP). Effects assessed with International Prostate Symptom Score, adverse events, and re-treatment rates were estimated from medical literature; treatments effects were modeled using a common baseline score. Starting with each therapy, patients’ transitions to more intensive therapies when symptoms returned were simulated in 6-month cycles over 2 years. Incremental cost-effectiveness ratios (ICERs) were calculated for pairs of treatments; uncertainty in ICERs was estimated with probabilistic sensitivity analyses. Results ComboRx was least effective and provided one-third of the symptom relief achieved with MITs. UroLift was similar in effectiveness to Prostiva and Rezūm but costs more than twice as much. The cheaper MITs were ~$900 more expensive than the cost of ComboRx generic drugs over 2 years. TURP and PVP provided slightly greater relief of LUTS than MITs at approximately twice the cost over 2 years; typically, they are reserved for treatment of more severe LUTS. Conclusion The analysis evaluated the costs and symptom relief of six treatment options in the continuum of care from a common baseline of LUTS severity. Identification of treatments for LUTS/BPH that

    The increasing prevalence of goiter and thyroid nodules in older patients is accompanied by an increasing frequency of treatment and cost. Cost-effectiveness is given for programs of prophylaxis (primary prevention, e.g. alimentary iodine supplementation), for programs of screening (secondary prevention. e.g. TSH-screening), and for therapeutic strategies to avoid complications of thyroid dysfunction (atrial fibrillation, myocardial infarction, death for cardiac reasons) and to minimize iatrogenic complications (tertiary prevention). Examples of tertiary prevention are radioiodine-therapy of Graves' disease in patients who have an increased risk of relapse after antithyroid drugs (ATD), radioiodine therapy of ouvert or subclinical hyperthyroidism, and radioiodine therapy of large goiters in older patients or in patients suffering from a relevant co-morbidity. A cost-effectiveness-analysis for different therapeutic strategies of Graves' disease has been published using a lifelong time-horizon. The ablative radioiodine dose-regime is cost-effective as a first line therapy if the risk of relapse after ATD exceeds 60%. Cost-minimization-analysis, comparing resection of goiter and radioiodine, has shown lower cost of radioiodine therapy for toxic multinodular goiter up to 100 ml and for Graves' disease up to 60 ml goiter volume. Medical aspects (volume of goiter, uptake of nodules, regressive goiter, suspicion on malignancy, patients' age, co-morbidity, patients' decision) remain decisive for the choice of treatment.

    Pilot studies of combined therapies treating benign nodular goiters reported promising results. The aim of this study was to investigate the effectiveness of combined microwave ablation (MWA) and radioiodine therapy (RIT) with a special focus on thyroid function at the 3-month follow-up. 15 patients (median age: 55 years) with a large goiter and benign thyroid nodules or Graves' disease were treated with the combined therapy. Serum levels of triiodothyronine (T3), thyroxine (T4), thyrotropin (TSH), thyroglobuline (Tg) and, additionally, antibody levels against thyroglobulin (TgAb), thyrotropin receptors (TRAb) and thyroid peroxidase (TPOAb) were measured at enrollment, post MWA and at the 3-month follow-up (3MFU). Furthermore, the goiter volume, I-131 dose and hospitalization time were analyzed to evaluate effectiveness. MWA was operated under local anesthesia with a system working in a wavelength field of 902 to 928 MHz. TSH, T4, T3 and Tg did not change at 3MFU, except for in two patients in whom the initial TSH levels improved to normal thyroid functioning levels at follow-up. One of the patients developed a high TRAb-level that receded back into the normal range. At 3MFU, the combined therapy showed a mean thyroid volume reduction of 26.4 ml ± 7.9 ml (30.5 % ± 4.6 % (p < 0.05)). By utilizing the combined therapy, administered activity could be reduced by 26.6 % ± 4.8 % (p < 0.05) and hospitalization time by 30.9 % ± 19.9 % (p < 0.05). The data confirmed the effectiveness of the combination of MWA with RIT. The combined therapy is an innovative and conservative approach and could become a safe alternative to surgery for the treatment of very large benign nodular goiters. Due to the short follow-up and the limited number of patients, further studies will be necessary.

    To evaluate short-term effects of balance Vestibular Rehabilitation Therapy (VRT) on balance, dizziness symptoms and quality of life of the elderly with chronic Benign Paroxysmal Positional Vertigo (BPPV). In this randomized, single-blind and controlled trial, older adults with chronic BPPV were randomized into two groups, the experimental group (n = 7, age: 69 (65-78) years) and the control group (n = 7, age: 73 (65-76) years). Patients in the experimental group underwent balance VRT (50 min per session, two times a week) and Canalith Repositioning Maneuver (CRM) as required, for 13 weeks. The control group was treated using only CRM as required. Standing and dynamic balance, dizziness symptoms and quality of life were measured at the baseline, and at one, five, nine and thirteen weeks. There were no between-group differences in dizziness, quality of life and standing balance over the 13 weeks. Significant differences were observed in dynamic balance measures between groups (p CRM. Implications for Rehabilitation The findings that balance VRT in addition to CRM improves dynamic balance in elderly people with BPPV should be useful in guiding rehabilitation professionals' clinical decision making to design interventions for seniors suffering from BPPV; Improvements in tests of dynamic balance suggest that the risk of adverse consequences of BPPV in the elderly such as falls and fractures can be potentially reduced through implementation of CRM in conjunction with balance VRT; Lack of additional improvement in Visual Analogue Scale of dizziness and Dizziness Handicap Index suggests that addition of balance VRT does not influence dizziness symptomatology, per se, and CRM alone is effective to ameliorate vertiginous symptoms and potentially improve quality of life.

    Benign prostatic hyperplasia and hypogonadism are common disorders in aging men. There is concern that androgen replacement in older men may increase prostate size and symptoms of benign prostatic hyperplasia. We examined whether combining dutasteride, which inhibits testosterone to dihydrotestosterone conversion, with testosterone treatment in older hypogonadal men with benign prostatic hyperplasia reduces androgenic stimulation of the prostate compared to testosterone alone. We conducted a double-blind, placebo controlled trial of 53 men 51 to 82 years old with symptomatic benign prostatic hyperplasia, prostate volume 30 cc or greater and serum total testosterone less than 280 ng/dl (less than 9.7 nmol/l). Subjects were randomized to daily transdermal 1% T gel plus oral placebo or dutasteride for 6 months. Testosterone dosing was adjusted to a serum testosterone of 500 to 1,000 ng/dl. The primary outcomes were prostate volume measured by magnetic resonance imaging, serum prostate specific antigen and androgen levels. A total of 46 subjects completed all procedures. Serum testosterone increased similarly into the mid-normal range in both groups. Serum dihydrotestosterone increased in the testosterone only but decreased in the testosterone plus dutasteride group. In the testosterone plus dutasteride group prostate volume and prostate specific antigen (mean ± SEM) decreased 12% ± 2.5% and 35% ± 5%, respectively, compared to the testosterone only group in which prostate volume and prostate specific antigen increased 7.5% ± 3.3% and 19% ± 7% (p = 0.03 and p = 0.008), respectively, after 6 months of treatment. Prostate symptom scores improved in both groups. Combined treatment with testosterone plus dutasteride reduces prostate volume and prostate specific antigen compared to testosterone only. Coadministration of a 5α-reductase inhibitor with testosterone appears to spare the prostate from androgenic stimulation during testosterone replacement in older

    Treatment of male lower urinary tract symptoms (LUTS) has traditionally focused on the management of benign prostatic obstruction, but the contribution of bladder dysfunction has been recently recognized. Therefore, it is well understood that LUTS have multifactorial etiology and often occur in clusters and not in isolation. Voiding LUTS are highly prevalent in men, but storage LUTS have been proved to be more bothersome. α1-Blockers are the most widely used pharmacologic agents for the treatment of symptoms relating to benign prostatic enlargement due to benign prostatic hyperplasia (BPH), while antimuscarinics are the drug class of choice for overactive bladder symptoms. A combination of the two drug classes would be a reasonable approach to treat men with both storage and voiding symptoms, and several short-term studies have proved the efficacy and safety of different combinations with an α1-blocker and an antimuscarinic. Following previous studies on the separate administration of solifenacin and tamsulosin, a fixed-dose combination tablet of tamsulosin oral controlled absorption system (OCAS) 0.4 mg and solifenacin succinate 6 mg has been recently introduced, and the current review evaluates the available data on the use of this fixed-dose combination in the treatment of LUTS in men with BPH.

    To estimate the long-term cost-effectiveness of single-dose dutasteride/tamsulosin combination therapy as a first-line treatment for benign prostatic hyperplasia (BPH) from the perspective of the UK National Health Service (NHS). A Markov state transition model was developed to estimate healthcare costs and patient outcomes, measured by quality-adjusted life years (QALYs), for patients aged ≥50 years with diagnosed BPH and moderate to severe symptoms. Costs and outcomes were estimated for two treatment comparators: oral, daily, single-dose combination therapy (dutasteride 0.5 mg + tamsulosin 0.4 mg), and oral daily tamsulosin (0.4 mg) over a period up to 25 years. The efficacy of comparators was taken from results of the Combination of Avodart and Tamsulosin (CombAT) trial. Cumulative discounted costs per patient were higher with combination therapy than with tamsulosin, but QALYs were also higher. After 25 years, the incremental cost-effectiveness ratio for combination therapy was £12,219, well within the threshold range (£20,000-£30,000 per QALY) typically applied in the NHS. Probabilistic sensitivity analysis showed that the probability of combination therapy being cost-effective given the threshold range is between 78% and 88%. Single-dose combination dutasteride/tamsulosin therapy has a high probability of being cost-effective in comparison to tamsulosin monotherapy in the UK's NHS. © 2013 BJU International.

    The purpose of this study was to determine whether magnetic resonance imaging (MRI) or quantitative color-imaged morphometric analysis (MA) of the prostate gland are related to the clinical response to terazosin. Thirty-six male patients with symptomatic benign prostatic hyperplasia (BPH) with a serum prostate-specific antigen level of 4-10 ng/mL underwent MRI with body coil, transrectal prostate unltrasonography and biopsy prior to terazosin therapy. For MRI-determined stromal and non-stromal BPH, the ratio of the signal intensity of the inner gland to the obturator internus muscle was evaluated. Histologic sections were stained with hematoxylin and eosin. The MA of the specimens was performed by Samba 2000. Results of the two techniques were interpreted according to the terazosin therapy results. The mean stromal percentage was 60.5{+-}18.0%. No statistically significant relationship was found between the clinical outcome of terazosin and the MRI findings. The MA results showed a significant relationship between the percentage of stroma and the percent change of the peak urinary flow rate, but not with the percent change of the international prostate symptom score after terazosin therapy (P<0.05). Magnetic resonance imaging alone is not sufficient in predicting the response to terazosin therapy. Morphometric analysis of BPH tissue composition can be used in predicting the clinical outcome of terazosin therapy but it is suitable only in patients for whom prostatic biopsy is necessary in order to rule out prostate cancer.

    Benign bone-forming tumors include osteomas, enostomas, osteoid osteomas, and osteoblastomas. These lesions are often characterized by typical imaging findings on radiographs, CT and MR imaging studies. Radiologic findings and additional clinical information allow for a specific diagnosis in most cases. This review article emphasizes the radiological patterns of benign boneforming tumors as well as their epidemiological, clinical, and pathological characteristics. In addition, minimally invasive interventional procedures for the therapy of osteoid osteoma are reviewed. (orig.) [de

    To assess the efficacy of dutasteride add-on therapy for patients with benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS) with small prostates who have been treated with α-blocker therapy for >3 months. A total of 110 men with clinical BPH were enrolled. There were 17 and 93 subjects with a prostate volume (PV) 3 months. Subjective and objective clinical variables were assessed using the total International Prostate Symptom Score (IPSS-T), IPSS quality of life (IPSS-QoL), IPSS voiding subscore (IPSS-V), IPSS storage subscore (IPSS-S), overactive bladder symptom score (OABSS), PV, prostate specific antigen (PSA) level, post-void residual (PVR), and maximum flow rate (Qmax). These variables were assessed at baseline and every 3 months for 1 year. In the small prostate group, IPSS-T and IPSS-V showed improvements from baseline at 6 and 9 months, storage subscore at 6 months, and OABSS at 3 months, but no sustained improvements were observed. During the study period, only the IPSS QoL scores did not show any improvement. Conversly, dutasteride was significantly effective at improving IPSS-T, IPSS-V, IPSS-S, and IPSS-QoL scores throughout the study period in the large prostate BPH group. PSA levels and PV significantly decreased in both groups throughout the study. Benign prostatic hyperplasia in LUTS patients with small prostates did not show a sustainable benefit from the addition of dutasteride to α-blocker therapy. © 2016 John Wiley & Sons Australia, Ltd.

    This study aimed to characterize the clinical features and outcomes of benign paroxysmal positional vertigo (BPPV) in the pediatric population. Retrospective case review. Tertiary care center. One hundred ten patients, aged 5 to 19 years old, diagnosed with BPPV. Patient demographics, comorbidities, canal involvement, response to treatment, and incidence of recurrence. BPPV was diagnosed in 19.8% of patients seen for dizziness during the study period. Patient age ranged 5 to 19 years old (mean =13.4 ± 3.4 yr). Female:male ratio was 3:2. The most prevalent comorbidities were concussion (n = 42, 38.2%) and migraine disorders (n = 33, 30.0%). Average time to diagnosis from symptom onset was 178.2 ± 190.8 days. The posterior canal was most frequently affected (n = 80, 72.7%), followed by the lateral canal (n = 37, 33.6%) and superior canal (n = 21, 19.1%), and 36.4% (n = 40) of patients had multiple canals affected. Treatment requiring more than or equal to five maneuvers to achieve resolution was observed in 11.8% of cases (n = 13). Recurrence was observed in 18.2% of cases. A logistic regression analysis demonstrated that patients with vestibular migraine or benign paroxysmal vertigo of childhood had five times higher odds of recurrence of BPPV, p = 0.003, 95% [1.735, 15.342], than those who did not have either. BPPV is a relatively common cause of dizziness in the pediatric population. Children and adolescents with BPPV can be successfully treated with repositioning maneuvers but may be at risk for treatment resistance and recurrence. Increased awareness of BPPV in pediatric patients may reduce delays in identification and treatment.

  1. Is bisphosphonate therapy for benign bone disease associated with impaired dental healing? A case-controlled study

    2011-01-01

    Background Bisphosphonates are common first line medications used for the management of benign bone disease. One of the most devastating complications associated with bisphosphonate use is osteonecrosis of the jaws which may be related to duration of exposure and hence cumulative dose, dental interventions, medical co-morbidities or in some circumstances with no identifiable aggravating factor. While jaw osteonecrosis is a devastating outcome which is currently difficult to manage, various forms of delayed dental healing may be a less dramatic and, therefore, poorly-recognised complications of bisphosphonate use for the treatment of osteoporosis. It is hypothesised that long-term (more than 1 year's duration) bisphosphonate use for the treatment of post-menopausal osteoporosis or other benign bone disease is associated with impaired dental healing. Methods/Design A case-control study has been chosen to test the hypothesis as the outcome event rate is likely to be very low. A total of 54 cases will be recruited into the study following review of all dental files from oral and maxillofacial surgeons and special needs dentists in Victoria where potential cases of delayed dental healing will be identified. Potential cases will be presented to an independent case adjudication panel to determine if they are definitive delayed dental healing cases. Two hundred and fifteen controls (1:4 cases:controls), matched for age and visit window period, will be selected from those who have attended local community based referring dental practices. The primary outcome will be the incidence of delayed dental healing that occurs either spontaneously or following dental treatment such as extractions, implant placement, or denture use. Discussion This study is the largest case-controlled study assessing the link between bisphosphonate use and delayed dental healing in Australia. It will provide invaluable data on the potential link between bisphosphonate use and osteonecrosis of the jaws

    To describe the clinical and laboratory features of benign acute childhood myositis. 40 children of BACM were seen during October 2001 to February 2002, 22 (52%) were male with mean age of 5.3 years. Duration of illness was 3.97 days. Preceding symptoms included fever, leg pain, vomiting and inability to walk. A provisional diagnosis of viral myositis was made in 26 (66%). Guillian Barre Syndrome was the most common referral diagnosis. 11 (27.5%) children had leucopenia with lymphocytic response and 16 (40%) had thrombocytopenia. CRP was negative in 32 (80%). CPK was markedly elevated (more than 1000 IU/l) in 18 (45%) and more than 500 IU/l in 11 (27.5%) remaining between 200 to 500 IU/l. Associated features were hepatitis (elevated SGOT & SGPT) in 28 (70%) and shock in 5 (12.5%). Serological test were indicative of dengue virus (Elisa PAN BIO) in 20 (50%) of which 8 (25%) were primary dengue and 12 (30%) were secondary dengue. The outcome of therapy mainly supportive were excellent. Benign acute myositis occurs often in association with viral infection. In the present study, Dengue virus was positive in 20 (50%) children. Benign acute myositis can be differentiated from more serious causes of walking difficulty by presence of calf and thigh muscle tenderness on stretching, normal power and deep tendon reflex and elevated CPK.

    Benign prostatic hyperplasia (BPH), an imbalance between androgen/estrogen, overexpression of stromal, and epithelial growth factors associated with chronic inflammation, has become an atypical direct cause of mortality of aged male diseases. Ginkgo possesses anti-inflammatory, blood flow-enhancing, and free radical scavenging effects. Considering strenuous exercise can reduce BPH risks, we hypothesize Ginkgo + exercise (Ginkgo + Ex) could be beneficial to BPH. To verify this, rat BPH model was induced by s.c. 3.5 mg testosterone (T) and 0.1 mg estradiol (E2) per head per day successively for 8 weeks, using mineral oil as placebo. Cerenin® 8.33 μL/100 g was applied s.c. from the 10th to the 13th week, and simultaneously, Ex was applied (30 m/min, 3 times/week). In BPH, Ginkgo alone had no effect on T, 5α-reductase, and dihydrotestosterone (DHT), but suppressed androgen receptor (AR), aromatase, E2 and estrogen receptor (ER), and the proliferating cell nuclear antigen (PCNA); Ex alone significantly reduced T, aromatase, E2, ER, AR, and PCNA, but highly raised DHT. While Ginkgo + Ex androgenically downregulated T, aromatase, E2, and ER, but upregulated DHT, AR, and PCNA, implying Ginkgo + Ex tended to worsen BPH. Conclusively, Ginkgo or Ex alone may be more beneficial than Ginkgo + Ex for treatment of BPH. PMID:23690843

    This prospective clinical study includes 96 BPPV patients with the results of DHI testing ≥ 40 points. They were segregated to be taken into this study and randomly divided into two therapy groups: 48 patients in Group I were treated pharmacotherapeutically with Betahistine Chloride (BC) and 48 patients in Group II underwent a rehabilitation treatment by performing an Epley maneuver. Total study duration was eight weeks, during which the patients were first examined upon arrival, checked after one, and rechecked after eight weeks. The tests included otoneurological examination and VNG, as well as completing three questionnaires: DHI, SF-36®, and HADS®. During the first checkup after one week, 86.96% of patients in Group I and 93.33% in Group II had negative results at the Dix-Hallpike test. During the second checkup after an eight weeks' treatment, 95.65% in Group I and 97.78% patients in Group II had a negative result. At the beginning of the study, the values of patients' physical, emotional, and functional health (QoL) were equally distributed in both therapy groups, compared to standardized values of healthy population. During the first checkup, the values were significantly higher and by the second checkup, reached the statistic average, which corresponds with the healthy population. There was an obviously faster and more complete recovery of the patients in Group II, who underwent a rehabilitation treatment.

    Full Text Available Benign prostatic hyperplasia (BPH is a disease that affects over 50% of males aged 50 years or older. In men aged >80 years, the incidence is 90%. BPH occurs in 9-25% of males aged 40 to 79 years. Fifty percent of patients with BPH are symptomatic. The symptoms include reduced urinary flow, nocturia, defective bladder emptying, urinary hesitancy, and dysuria. Disease progression can be associated with acute urinary retention (AUR. Prostatic obstruction includes mechanical and dynamic components, the latter mediated by alpha-muscarinic receptors. Treatment with alpha-1-blockers (alfuzosin, doxazosin, tamsulosin, and terazosin leads to rapid amelioration of symptoms and urinary flow, usually within one or two weeks. The 5-alpha reductase inhibitors (5-ARIs are “disease-modifying drugs.” They control the growth of the prostate by blocking the conversion of testosterone into dihydrotestosterone (DHT. Finasteride is a 5–ARI that is selective for type 2 receptors. Dutasteride is a powerful inhibitor of both 5- alpha reductase isoforms (type 1 and 2 and produces more complete suppression of DHT synthesis than finasteride. Dutasteride also has a much longer half-life than finasteride (five weeks versus five to six hours. The authors review the results of clinical trials involving finasteride and dutasteride, with and without alpha-1-blockers, highlighting the important role of dutasteride in improving acute urinary retention and eliminating the need for surgical therapy.

The aim of this study was to show the impact of pharmacological treatment for BPH on prostate volume (PV and levels of freeT and, consequently, on urinary parameters and sexual desire in men during 6 months of administration. Methods. This clinical prospective study included 156 BPH patients with moderate urinary symptoms – International Prostate Symptom Score (IPSS 30 mL and prostate specific antigen (PSA value < 4 ng/mL. The average age of patients was 61.16 ± 2.97 years. The performed tests included determination of tumor markers (PSA, free PSA, hormones (totalT, freeT, freeT/totalT ratio, trans abdominal ultrasonography and uroflowmetry. Urinary symptoms were measured by IPSS and the Quality of Life (QoL questionnaire while the changes in sexual desire were measured using the International Index of Erectile Function (IIEF questionnaire. Four groups were formed, 39 patients each. The group 1 received alpha1- blocker (AB tamsulosin, the group 2, 5 alpha-reductase inhibitor (5-ARI finasteride, the group 3, combined therapy of both drugs (tamsulosin and finasteride, while the group 4 (control group had no therapy. Follow-ups were performed every three and six months during therapy administration. Results. Prostate volume significantly decreased in the patients on combined therapy (-6.95 ± 2.00; p < 0.001 and finasteride (-6.67 ± 3.35. In the finasteride group, the levels of freeT (-4.23 ± 5.2; p < 0.001 and freeT/totalT ratio (-0.12 0.08; p < 0.001 significantly decreased as did the freeT (-2.64 ± 7.81 and freeT/totalT ratio (-0.09 ± 0.13 in the combined therapy group. Uroflowmetry showed a significant improvement in all parameters and all the therapy groups. Combined

    Photodynamic therapy (PDT) is a promising treatment for various skin tumors and other skin diseases. We investigated the potential therapeutic effects of PDT using ATX-S10(Na) ointment and a diode laser in mouse skin models of experimental skin tumors as well as transplanted human samples of superficial skin tumors and lesional psoriatic skin. ATX-S10(Na) ointment (1% w/v) was introduced into tape-stripped mouse skin, transplanted squamous cell carcinoma (SCC) samples and human skin diseases after topical application, then PDT was performed. ATX-S10(Na) ointment (1% w/v) was introduced effectively into tape-stripped mouse skin and transplanted SCC samples after topical application, but was not detected after 48 h, as assessed by fluorescence microscopy. PDT, using 1% ATX-S10(Na) ointment and diode laser (50 J/cm(2)), was found to decrease epidermal thickness in 12-0-tetradecanoylphorbol-13-acetate (TPA)-treated mouse skin by 6 days. PDT with 1% ATX-S10(Na) ointment and diode laser (150 J/cm(2)) was also effective for transplanted SCC, and tumors were eliminated by 6 weeks. PDT against Bowen disease, basal-cell carcinoma, and psoriasis xenografts onto SCID mice also showed marked suppression of tumor growth and cell proliferation, respectively. Our results indicate that ATX-S10(Na)-PDT is an effective treatment for various skin tumors and psoriasis in experimental mouse models.

    Benign prostatic hyperplasia (BPH) is a result of urogenital aging. Recent studies suggest that an age-related impairment of the blood supply to the lower urinary tract plays a role in the development of BPH and thus may be a contributing factor in the pathogenesis of BPH. The canine prostate is a model for understanding abnormal growth of the human prostate gland. We studied the efficacy of pulsed electromagnetic field therapy (PEMF) in dogs to modify prostate blood flow and evaluated its effect on BPH. PEMF (5 min, twice a day for 3 weeks) was performed on 20 dogs affected by BPH. Prostatic volume, Doppler assessment by ultrasonography, libido, semen quality, testosterone levels, and seminal plasma volume, composition and pH were evaluated before and after treatment. The 3 weeks of PEMF produced a significant reduction in prostatic volume (average 57%) without any interference with semen quality, testosterone levels or libido. Doppler parameters showed a reduction of peripheral resistances and a progressive reduction throughout the trial of the systolic peak velocity, end-diastolic velocity, mean velocity, mean, and peak gradient of the blood flow in the dorsal branch of the prostatic artery. The pulsatility index and the resistance index did not vary significantly over time. The efficacy of PEMF on BPH in dogs, with no side effects, suggests the suitability of this treatment in humans and supports the hypothesis that impairment of blood supply to the lower urinary tract may be a causative factor in the development of BPH. © 2014 The Authors.

    Full Text Available Konstantinos Dimitropoulos, Stavros Gravas Department of Urology, Faculty of Medicine, School of Health Sciences, University of Thessaly, Larissa, Greece Abstract: Treatment of male lower urinary tract symptoms (LUTS has traditionally focused on the management of benign prostatic obstruction, but the contribution of bladder dysfunction has been recently recognized. Therefore, it is well understood that LUTS have multifactorial etiology and often occur in clusters and not in isolation. Voiding LUTS are highly prevalent in men, but storage LUTS have been proved to be more bothersome. α1-Blockers are the most widely used pharmacologic agents for the treatment of symptoms relating to benign prostatic enlargement due to benign prostatic hyperplasia (BPH, while antimuscarinics are the drug class of choice for overactive bladder symptoms. A combination of the two drug classes would be a reasonable approach to treat men with both storage and voiding symptoms, and several short-term studies have proved the efficacy and safety of different combinations with an α1-blocker and an antimuscarinic. Following previous studies on the separate administration of solifenacin and tamsulosin, a fixed-dose combination tablet of tamsulosin oral controlled absorption system (OCAS 0.4 mg and solifenacin succinate 6 mg has been recently introduced, and the current review evaluates the available data on the use of this fixed-dose combination in the treatment of LUTS in men with BPH.

    To evaluate the efficacy and safety of a combination therapy with dutasteride and imidafenacin in patients with benign prostatic hyperplasia and persistent overactive bladder symptoms. A total of 163 patients presenting an enlarged prostate (volume >30 mL) and persistent overactive bladder symptoms despite at least 8 weeks of tamsulosin were randomized to receive tamsulosin and dutasteride, or tamsulosin, dutasteride and imidafenacin at a 1:1 ratio. The primary end-point was the mean change from baseline to week 24 in total overactive bladder symptom score. The mean change in total overactive bladder symptom score from baseline at week 24 was -1.99 (95% confidence interval -2.57 to -1.41) in the tamsulosin and dutasteride group, and -3.12 (95% confidence interval -3.72 to -2.52) in the tamsulosin, dutasteride and imidafenacin group. The tamsulosin, dutasteride and imidafenacin group significantly improved total overactive bladder symptom score at week 24 as compared with the tamsulosin and dutasteride group; the mean difference was -1.18 (-2.02 to -0.34). The between-group difference was statistically significant as early as week 4. The total International Prostate Symptom Score, storage subscore, quality of life index, and benign prostatic hyperplasia impact index also significantly improved in the tamsulosin, dutasteride and imidafenacin group. Tamsulosin, dutasteride and imidafenacin combination therapy improves overactive bladder symptoms and quality of life without causing serious adverse drug reactions in patients with enlarged prostate not responding to tamsulosin. This combination therapy seems to represent a promising therapeutic option in these patients. © 2017 The Japanese Urological Association.

    Ductal adenocarcinoma is the most frequent solid tumor of the pancreas. This tumor has distinct features including early obstruction of the pancreatic duct, diminished enhancement after administration of contrast material due to desmoplastic growth, high propensity to infiltrate adjacent structures and to metastasize into the liver and the peritoneum. Hormone active endocrine tumors cause specific clinical symptoms. Imaging is aimed at localization of these hypervascular tumors. Non hormone active tumors are most frequently malignant and demonstrate very varying features. Cystic pancreatic tumors are increasingly detected by means of cross sectional imaging. Exact classification can be achieved with knowledge of the macropathology and considering clinical presentation as well as age and gender of the patients. (orig.)

    Recent data indicate that 25 to 30% of the population in industrialized countries suffers from benign chronic pain. Among these patients, 50 to 75% are professionally incapable for varied lengths of time, from a few days to some weeks or months, or even definitively. The aetiology and clinical presentation of chronic benign pain are enormously varied because this definition includes such different pathologies as headache, pain of rheumatologic, postsurgical, organic, and post-zoster origin, lombalgia, radiculalgia, post-amputation pain, neuropathologic pain, causalgia, algoneurodystrophic pain, psychosomatic and idiopathic pain. Since these syndromes and causes of pain could not be discussed individually, they have been grouped according to their neurophysiology and pathophysiology.

    There is little information in the literature concerning the role of bone scanning in benign bone neoplasms except for sporadic reports. Since the advent of /sup 99m/Tc-polyphosphate, bone imaging has proven feasible and useful in locating the cause of bone pain, such as in osteoid osteomas, which are not always radiologically apparent, and in evaluating whether or not a radiologic lesion is indeed benign and solitary. Blood-pool images are particularly important in neoplastic disease, since the absence of hyperemia in the immediate postinjection period favors the diagnosis of a benign neoplasm, as does low-grade uptake on the delayed study. The scan, including pinhole magnification images, is especially valuable in diagnosing lesions in the spine and pelvis, which are poorly seen radiologically. We have studied various types of benign bone tumors, including simple and aneurysmal bone cysts, fibrous cortical defects, and nonossifying fibromas, all of which had minimal or no increased uptake of the radiopharmaceutical, unless traumatized. Although osteochondromas and enchondromas showed varied accumulation of activity, the scan was useful in differentiating these from sarcomatous lesions. All osteoid osteomas demonstrated marked activity, and could be accurately located preoperatively, as could the extent of fibrous dysplasia. The bone scan in the reticuloses also showed abnormal accumulation of activity, and aided in arriving at the prognosis and treatment of histiocytic bone lesions

    The gastric lesion is a common source of complaints to Orientals, however, evaluation of gastric symptoms and laboratory examination offer little specific aid in the diagnosis of gastric diseases. Thus roentgenography of gastrointestinal tract is one of the most reliable method for detail diagnosis. On double contract study of stomach, gastric filling defect is mostly caused by malignant gastric cancer, however, other benign lesions can cause similar pictures which can be successfully treated by surgery. 66 cases of benign causes of gastric filling defect were analyzed at this point of view, which was verified pathologically by endoscope or surgery during recent 7 years in Yensei University College of Medicine, Severance Hospital. The characteristic radiological picture of each disease was discussed for precise radiologic diagnosis. 1. Of total 66 cases, there were 52 cases of benign gastric tumor 10 cases of gastric varices, 5 cases of gastric bezoar, 5 cases of corrosive gastritis, 3 cases of granulomatous disease and one case of gastric hematoma. 2. The most frequent causes of benign tumors were adenomatous polyp (35/42) and the next was leiomyoma (4/42). Others were one of case of carcinoid, neurofibroma and cyst. 3. Characteristic of benign adenomatous polyp were relatively small in size, smooth surface and were observed that large size, benign polyp was frequently type IV lesion with a stalk. 4.

    The majority of men will develop symptoms of benign prostatic hyperplasia (BPH) after 70 years of age. Various studies indicate that antagonists of LHRH, such as cetrorelix, exert direct inhibitory effects on BPH mediated by specific LHRH receptors. Our aim was to investigate the mRNA for LHRH and LHRH receptors and the expression of LHRH receptors in specimens of human BPH. The expression of mRNA for LHRH (n=35) and LHRH receptors (n=55) was investigated by RT-PCR in surgical specimens of BPH, using specific primers. The characteristics of binding sites for LHRH on 20 samples were determined by ligand competition assays. The LHRH receptor expression was also examined in 64 BPH specimens by immunohistochemistry. PCR products for LHRH were found in 18 of 35 (51%) BPH tissues and mRNA for LHRH receptors was detected in 39 of 55 (71%) BPH specimens. Eighteen of 20 (90%) samples showed a single class of high affinity binding sites for [D-Trp(6) ]LHRH with a mean K(d) of 4.04 nM and a mean B(max) of 527.6 fmol/mg membrane protein. LHRH antagonist cetrorelix showed high affinity binding to LHRH receptors in BPH. Positive immunohistochemical reaction for LHRH receptors was present in 42 of 64 (67%) BPH specimens. A high incidence of LHRH receptors in BPH supports the use of LHRH antagonists such as cetrorelix, for treatment of patients with lower urinary tract symptoms from BPH.

    Martínez Gamarra, C; Bernabéu Taboada, D; Pozo Kreilinger, J J; Tapia Viñé, M

    Benign notochordal cell tumors (TBCN) are lesions with notochordal differentiation which affect the axial skeleton. They are characterized by asymptomatic or non-specific symptomatology and are radiologically unnoticed because of their small size, or because they are mistaken with other benign bone lesions, such as vertebral hemangiomas. When they are large, or symptomatic, can be differential diagnosis with metastases, primary bone tumors and chordomas. We present a case of a TBCN in a 50-year-old woman, with a sacral lesion seen in MRI. A CT-guided biopsy was scheduled to analyze the lesion, finding that the tumor was not clearly recognizable on CT, so the anatomical references of MRI were used to select the appropriate plane. The planning of the approach and the radio-pathological correlation were determinant to reach the definitive diagnosis. Copyright © 2017 SERAM. Publicado por Elsevier España, S.L.U.

    The aim of study was to evaluate the influence of ageing, lifestyle, and co morbid illnesses on treatment outcome of nocturia among men with BPH. Patients with BPH on medical therapy of least 6 months and up to 48 months were interviewed. Nocturia episodes, co morbid illnesses, beverage intake frequency, medications and work history were documented. Body Mass Index (BMI), waist circumference (WC), prostate volume, and prostate specific antigen (PSA) were recorded. Treatment failure is defined as persistent nocturia despite on medical therapy for BPH. In 156 patients, the prevalence of nocturia was 96.7% while nocturia of 2 or more was 85.9%. Factors associated with treatment failure was older age (p coffee intake (p = 0.02) were associated with nocturia improvement. Co-morbid illnesses, obesity, WC, alcohol intake, PSA, prostate volume, and use of BPH medical therapy did not influence treatment outcome. Advancing age has a significance negative outcome on nocturia treatment, while standard BPH medical therapy and co morbid illnesses have an insignificant impact. However, alleviation of bothersome symptoms is possible with the understanding of its patho-physiology and individual-based approach to treatment and expected outcome.

  12. Pharmacological treatment of the benign prostatic hyperplasia

    2011-01-01

    Benign prostatic hyperplasia is a common disease in over 50 years-old men consisting in uncontrolled and benign growth of prostatic gland that leads to lower urinary tract symptoms. The etiology of benign prostatic hyperplasia is multifactoral involving the increased conversion of testosterone in dihydrotestosterone by the prostatic 5α-reductase action, which brought about events that encourage the prostate growth (static component) and the increase of the bladder and prostate smooth muscle tone (dynamic component) regulated by the aα 1 -adrenoceptors (ADR). The pharmacological treatment of the benign prostatic hyperplasia includes the prostatic 5aα-reductase inhibitors, the aα 1 -adrenoreceptor blockers, their combined therapy and the phytotherapy. This paper was aimed at presenting the most relevant aspects of the pharmacology of drugs used for treating the benign prostatic hyperplasia, and providing elements to analyze their efficacy, safety and tolerability. To this end, a review was made of the different drugs for the treatment of this pathology and they were grouped according to their mechanism of action. Natural products were included as lipid extracts from Serenoa repens and Pygeum africanum as well as D-004, a lipid extract from Roystonea regia fruits, with proved beneficial effects on the main etiological factors of benign prostatic hyperplasia. D-004 is a prostatic 5a-reductase inhibitor, an aα 1 -adrenoceptor antagonist, aα 5-lipooxygenase inhibitor and has antioxidant action, all of which reveals a multifactoral mechanism. The results achieved till now indicate that D-004 is a safe and well-tolerated product

    Background. In pediatrics, pneumatosis intestinalis (PI) is usually due to necrotizing enterocolitis in premature newborns. Beyond infancy, PI is uncommon. ''Benign pneumatosis'' is PI in patients with few or no symptoms that resolves with conservative management. Objective. Our goal was to better characterize benign PI in children. Our investigation focused on identifying underlying risk factors, symptoms at time of diagnosis, management and outcome. Materials and methods. Available medical records and radiographs of children with pneumatosis intestinalis from 1990 to 1998 were reviewed for underlying conditions, symptoms at time of radiographs, management and outcome. Results. Thirty-seven children (mean age 4 years) were included. Thirty-two children had identifiable risk factors. Twenty -five children were immunocompromised by their underlying conditions or therapeutic regimen. Thirty-five children were managed conservatively with resolution of PI. Two patients, however, required surgery and one patient died. Conclusion. Benign pneumatosis does occur in children. The majority have underlying risk factors, most commonly related to immunosuppression. Clinical deterioration is the most useful indicator for surgical intervention. In most patients PI resolves with conservative management. (orig.)

Treatment techniques for transurethral convective radiofrequency water-vapor thermal therapy and outcomes with up to 12 months’ follow-up are presented. Materials and methods: A total of 131 patients with moderate–severe LUTS were included in a retrospective analysis of BPH procedures with the Rezūm system. Pre- and postprocedure assessments included International Prostate Symptom Score (IPSS, quality of life, peak urinary flow rate, voided volume, and postvoid residual urine volume. Urologists used their own discretion for patient selection, with variable prostate sizes, LUTS severity, urinary retention, or presence of an obstructing median lobe. Safety signals and surgical retreatment rates were monitored prospectively. Results: Men aged 47–96 years with prostates 13–183 cm3 showed significant improvement in IPSS, quality of life, and postvoid residual volume durable through 12 months after thermal therapy. Patients with either moderate (IPSS 8–19 or severe (IPSS 20–35 symptoms achieved significantly improved scores. Postprocedure adverse events normally anticipated and related to endoscopic instrumentation were transient and mild–moderate in nature. No de novo erectile or ejaculatory dysfunction was reported. Conclusion: This study corroborates prior published pilot and randomized controlled trial results indicating significant relief of urinary symptoms and reproducibility of responses to thermal

    Full Text Available Benign fibroosseous lesions represent a group of lesions that share the same basic evolutive mechanism and are characterized by replacement of normal bone with a fibrous connective tissue that gradually undergoes mineralization. These lesions are presented by a variety of diseases including developmental, reactive-dysplastic processes and neoplasms. Depending on the nature and amount of calcified tissue, they can be observed as radiolucent, mixed or radiopaque. Their radiographic features could be well-defined or indistinguishable from the surrounding bone tissue. They can be asymptomatic as in osseous dysplasias and can be detected incidentally on radiographs, or they can lead to expansion in the affected bone as in ossifying fibroma. All fibroosseous lesions seen in the jaws and face are variations of the same histological pattern. Therefore, detailed clinical and radiographic evaluation in differential diagnosis is important. In this review, fibroosseous benign lesions are classified as osseous dysplasia, fibrous dysplasia and fibroosseous tumors; and radiographic features and differential diagnosis of these lesions are reviewed taking into account this classification.

    Full Text Available Benign paroxysmal positional vertigo (BPPV is a common clinical disorder characterized by brief recurrent spells of vertigo often brought about by certain head position changes as may occur with looking up, turning over in bed, or straightening up after bending over. It is important to understand BPPV not only because it may avert expensive and often unnecessary testing, but also because treatment is rapid, easy, and effective in >90% of cases. The diagnosis of BPPV can be made based on the history and examination. Patients usually report episodes of spinning evoked by certain movements, such as lying back or getting out of bed, turning in bed, looking up, or straightening after bending over. At present, the generally accepted recurrence rate of BPPV after successful treatment is 40%-50% at 5 years of average follow-up. There does appear to be a subset of individuals prone to multiple recurrences.

    2016-01-01

    The most important causes of recurrence of benign pleomorphic adenoma are enucleation with intraoperative spillage and incomplete tumor excision in association with characteristic histologic findings for the lesion (incomplete pseudocapsule and the presence of pseudopodia). Most recurrent pleomorphic adenomas (RPAs) are multinodular. MRI is the imaging method of choice for their assessment. Nerve integrity monitoring may reduce morbidity of RPA surgery. Although treatment of RPA must be individualized, total parotidectomy is generally recommended given the multicentricity of the lesions. However, surgery alone may be inadequate for controlling RPA over the long term. There is growing evidence from retrospective series that postoperative radiotherapy results in significantly better local control. A high percentage of RPAs are incurable. All patients should therefore be informed about the possibility of needing multiple treatment procedures, with possible impairment of facial nerve function, and radiation therapy for RPA. Reappearance of Warthin tumor is a metachronous occurrence of a new focus or residual incomplete excision of all primary multicentric foci of Warthin tumor. Selected cases can be observed. Conservative surgical management can include partial superficial parotidectomy or extracapsular dissection. Not uncommonly, other major and minor salivary gland neoplasms, including myoepithelioma, basal cell adenoma, oncocytoma, canalicular adenoma, cystadenoma, and ductal papilloma, follow an indolent course after surgical resection, with rare cases of recurrence. © 2016 S.

    Full Text Available : Benign laryngeal lesions are commonly encountered causes of dysphonia and are often surgically correctable. A prospective study on 62 cases selected for videolaryngoscopic surgery was undertaken in a single unit in the department of ENT, Medical College Hospital, Thiruvananthapuram. The male: female ratio was 1.8:1 and the most common affected age group was 35-45 yrs. The most common benign lesion was vocal polyp. Preoperative voice assessment and 70 degree endoscopy was done. Follow up visits were done at 1 week, 3 weeks and 6 weeks and voice assessment and laryngoscopic appearances were noted. 98% reported excellent improvement of voice. The varieties of benign lesions which cause hoarseness are sources of concern and worry as it can affect the self esteem of a person.

  3. Nihilism: a benign denial.

    2003-06-01

    Nihilism is the belief that all possible knowledge on a given topic has been amassed and codified. Ranging from benign denial to deliberate attempts at excommunication, nihilism is often encountered in the history of medicine. Eustachius, Columbus, and Sylvius strongly criticized Vesalius and defended the authority of Galen. Riolan fervently rejected Harvey's monumental work on the circulation of blood. Gross stated that no honest and sensible surgeon would ever sanction thyroidectomy. Sandstrom's discovery of the parathyroids was met with silence. Transplantation of parathyroids by Mandl was not appreciated when announced. Aristotle's dictum that the heart cannot withstand serious injury led to Paget's statement that cardiac surgery had reached the limits set by nature, which no new techniques could overcome. The first Billroth I operation was welcomed as, "Hopefully, also the last." Pancreatic surgery was opposed because the organ was of no clinical interest and was impossible for surgeons to reach. Pancreatic transplantation was rejected for many years, despite good results. When Blundell used blood transfusion for postpartum hemorrhage, critics averred that his next exploit would be radical removal of the spleen. Bassini stated that it could be risky to publish more about radical treatment of inguinal hernias. Carcinomas of the lower sigmoid and upper rectum were deemed untreatable because of their inaccessibility. Colostomy during pediatric surgery was rejected many times. Although it is difficult for the human mind to move from a familiar point of view, this propensity should not infect science, thereby impeding advancement.

    International Nuclear Information System (INIS)

    1. In Berlin (West), X-ray therapy was applied during the year 1973 in 18 hospitals and by 33 practicing physicians. The 3rd quarter of the year 1973 was taken as basis for the frequency of therapeutic X-ray application. From a total of 15912 patients, 9432 were X-rayed on account of malignant diseases, 6480 because of benigne diseases. This number definitely surpasses the number of cases treated in Munich by X-ray therapy. In Berlin, this might be connected to the age structure. 2. Utilizing the quotations and calculations put down in the report about the effect of atomic radiation by the Scientific Committee of the United Nations, and the values quoted for gonadal doses in the literature, a total-GSD-value of 0.82 +- 0.2 mrem/a was calculated for hospitals and practicing physicians in Berlin. In spite of higher frequencies, this value is approximately of the same order of magnitude as the values calculated for Munich for the year 1971 by I. and H.P. Schmelz. 3. The total-GSD-value for the population of the Federal Republic of Germany resulting from artificial radiation exposure during 1976 is reported to be approximately 60 mrem. Thus, the GSD-value for the X-ray therapy of benign diseases lies approximately at 1.3% and should be of minor significance for radiation-hygienic reflections. 4. Of primary concern is still the radiation exposure to individual patients. Because of possible secondary effects, X-ray therapy for keloids and hemangiomas in infancy and youth are of particular significance. For this reason, its proportion to GSD is also in Berlin relatively large. (orig.) [de

    The coupling of energetic metallic multilayers (a.k.a. flash metal) with energetic sol-gel synthesis and processing is an entirely new approach to forming energetic devices for several DoD and DOE needs. They are also practical and commercially viable manufacturing techniques. Improved occupational safety and health, performance, reliability, reproducibility, and environmentally acceptable processing can be achieved using these methodologies and materials. The development and fielding of this technology will enhance mission readiness and reduce the costs, environmental risks and the necessity of resolving environmental concerns related to maintaining military readiness while simultaneously enhancing safety and health. Without sacrificing current performance, we will formulate new impact initiated device (IID) compositions to replace materials from the current composition that pose significant environmental, health, and safety problems associated with functions such as synthesis, material receipt, storage, handling, processing into the composition, reaction products from testing, and safe disposal. To do this, we will advance the use of nanocomposite preparation via the use of multilayer flash metal and sol-gel technologies and apply it to new small IIDs. This work will also serve to demonstrate that these technologies and resultant materials are relevant and practical to a variety of energetic needs of DoD and DOE. The goal will be to produce an IID whose composition is acceptable by OSHA, EPA, the Clean Air Act, Clean Water Act, Resource Recovery Act, etc. standards, without sacrificing current performance. The development of environmentally benign stab detonators and igniters will result in the removal of hazardous and toxic components associated with their manufacturing, handling, and use. This will lead to improved worker safety during manufacturing as well as reduced exposure of Service personnel during their storage and or use in operations. The

    Objective: To determine the frequencies of various benign breast diseases (BBD) in female patients in three private hospitals of Hyderabad. Methodology: This is a prospective cohort study of all female patients visiting the surgical clinic with breast problems. This study was conducted at Isra University Hospital Hyderabad and two other private hospitals of Hyderabad over a period of about three years starting from March 2004 to February 2007. All female patients visiting the surgical clinic with breast problems were included in the study. Patients with obvious clinical features of malignancy or those who on work up were diagnosed as carcinoma were excluded from the study. Results: A total of 275 patients were included in the study. About 44% (120/275) patients belonged to third decade of life (age between: 21-30 years) followed by 33% from forth decade (age between: 31- 40 years). Fibroadenoma was the most common benign breast disease, seen in 27% (75/275) of patients, followed by fibrocystic disease seen in about 21% (57/275) patients. Conclusion: Benign Breast Diseases (BBD) are common problems in females of reproductive age. Fibroadenoma is the commonest of all benign breast disease in our set up mostly seen in second and third decade of life. Fibrocystic disease of the breast is the next common BBD whose incidence increases with increasing age. (author)

    Numerous benign cysts or solid tumors may present in the jaws. These arise from tooth-forming tissues in the dental alveolus or from nonodontogenic tissues in the basal bone of the mandible and maxilla. Radiologists provide 2 deliverables to assist in diagnosis and management: (1) appropriately formatted images demonstrating the location and extent of the lesion and (2) interpretive reports highlighting specific radiologic findings and an impression providing a radiologic differential diagnosis. This article provides guidance on essential image protocols for planning treatments, a radiologic differential diagnostic algorithm based on location and pattern recognition, and a summary of the main features of benign odontogenic lesions.

  19. Radiation for not-so-benign coronary artery disease

    International Nuclear Information System (INIS)

    Massullo, Vincent

    1996-01-01

    The role of radiation therapy in the treatment of malignant disease has long been accepted. More limited application of radiation in the treatment of benign conditions has been proven but generally not pursued. On the centennial anniversary of radiation therapy, a promising, but as yet unproved, application of radiation for treatment of benign vascular disease has become an exciting field of research, speculation, and controversy. This panel presentation will discuss the rationales and dilemmas of applying radiation in the prevention of arterial restenosis after therapeutic intervention. Coronary artery bypass grafting and more recently coronary angioplasty have become accepted, effective therapies to reverse significant coronary stenosis, and thereby benefit the majority of patients with coronary artery disease. However, a large proportion of patients will suffer restenosis in spite of optimal conventional therapy. The search for a means to prevent such restenosis has been partially successful by therapies, and even engineering intravascular devices. In spite of these efforts, a significant number of patients will fail today's conventional therapy and suffer arterial restenosis. Fibroblast myointimal proliferation is felt to be a major element in this restenosis process. Clinical experience shows that radiation inhibits other similar benign fibroblast proliferative processes such as keloid scar formation and heterotopic ossification. Radiation is now being considered as a means to inhibit myointimal fibroblast proliferation and hopefully prevent attendant arterial restenosis as well. This has catalyzed various animal model investigations that have shown significant arteries. Promising results in the animal model and in very early human institutional trials. These trials are designed to determine if radiation is truly effective and can be safely delivered to prevent restenosis in diseased human arteries. This panel discussion will provide a firm basic science and

    Rubeinstein Jonathan N.

    2003-01-01

    Full Text Available Transurethral resection of the prostate (TURP remains the gold standard for treatment of benign prostatic hyperplasia (BPH. In general, while this procedure is safe, patients require a spinal, epidural, or general anesthesia and often several days of hospital stay; the potential morbidity and mortality limits the use of TURP in high-risk patients. Pharmacotherapy has been recommended as a first-line therapy for all patients with mild to moderate symptoms. Patients are oftentimes enthusiastic if they are offered a one-time method to treat lower urinary tract symptoms secondary to BPH, provided that the method offers reduced risk and allows an efficacy equal to that of medical therapy. One such method is transurethral microwave thermotherapy (TUMT. TUMT involves the insertion of a specially designed urinary catheter with a microwave antenna, which heats the prostate and destroys hyperplastic prostate tissue. TUMT allows the avoidance of general or regional anesthesia, and results in minimal blood loss and fluid absorption. In this review, the authors discussed the current indications and outcome of TUMT, including the history of the procedure, the mechanism of action, the indications for TUMT, the pre-operative considerations, the patient selection, the results in terms of efficacy, by comparing TUMT vs. Sham, TUMT vs. Alpha-blocker and TUMT vs. TURP. Finally, the complications are presented, as well as other uses and future directions of the procedure. The authors concluded that TUMT is a safe and effective minimally invasive alternative to treatment of symptomatic BPH.

    Palencia, R

    To carry out, by means of a literature review, an update of the entities that can be included within the group of benign partial epilepsies of childhood. Among partial epilepsies with onset in the first stages of life, a group extended in the last years with a favourable course and a trend to reverse, even spontaneously, has been identified. Some of these entities have a genetic origin but we do not know the mechanisms by which these epilepsies show a self limited course, which have given rise to the denomination of epilepsy that comes and goes; nevertheless, an evolution to other more complex forms is also possible. Benign partial epilepsies of childhood constitute a wide group of conditions of varied semiology, usually with a good prognosis even without treatment. Occasionally, these epilepsies may show a more unfavourable course with a worsening, in spite of medication, and the appearance of neurologic and neuropsychologic disorders. All these aspects must be known and considered by the physician in charge of these patients management.

    We report our experience with 43 retroperitoneal laparoscopic nephrectomy for benign kidney disease. All patients had a poor function from obstructive uropathology and renal atrophy. None of these patients had a previous lumbotomy. Retroperitoneoscopy was performed with 4 trocar port technique in a lateral position. The retroperitoneal space is created by using a Gaur's balloon made of sterile glove. The approach to vascular pedicle was done posteriorly and vessels were clipped by metal and Hem-o-lock (Weck Closure Systems, North Carolina, USA) clips. The sample was intact extracted in an Endo-Bag prolonging one trocar incision. Median operative time was 160 minutes and median blood loss was 200 mL. Four cases (9%) were converted to open surgery: one case due to bleeding and 3 cases due to technical difficulties regarding perirenal adherences. Most patients (39) checked out from the Hospital in day two. Four of them were left over 3 days due to wound complications. Retroperitoneoscopy offers a safe, effective and reproductive access to nephrectomy for benign pathologies.

    Hemihypertrophy is associated with malignant visceral abdominal neoplasms in childhood. Benign nephromegaly and nephroblastomas are both known to occur with hemihypertrophy; however, association with renal dysplasia has not previously reported. We describe an infant presenting with recurrent haematuria who had segmental hemihypertrophy, ipsilateral renal dysplasia and contralateral benign nephromegaly. Although debated, renal dysplasia may predispose to and predate malignant change. Rational management and optimal surveillance of renal dysplasia and benign nephromegaly in hemihypertrophy is discussed.

    2009-05-01

    Work on the classification of epileptic syndromes is ongoing, and many syndromes are still under discussion. In particular, special difficulty still persists in correctly classifying epilepsies with myoclonic seizures. The existence of special familial epileptic syndromes primarily showing myoclonic features has been recently suggested on the basis of a clear pattern of inheritance or on the identification of new chromosomal genetic loci linked to the disease. These forms in development include familial infantile myoclonic epilepsy (FIME), benign adult familial myoclonic epilepsy (BAFME), or autosomal dominant cortical myoclonus and epilepsy (ADCME), and, maybe, adult-onset myoclonic epilepsy (AME). In the future, the identification of responsible genes and the protein products will contribute to our understanding of the molecular pathways of epileptogenesis and provide neurobiologic criteria for the classification of epilepsies, beyond the different phenotypic expression.

  6. Design of environmentally benign processes

    1999-01-01

    This paper presents a hybrid method for design of environmentally benign processes. The hybrid method integrates mathematical modelling with heuristic approaches to solving the optimisation problems related to separation process synthesis and solvent design and selection. A structured method...... of solution, which employs thermodynamic insights to reduce the complexity and size of the mathematical problem by eliminating redundant alternatives, has been developed for the hybrid method. Separation process synthesis and design problems related to the removal of a chemical species from process streams...... because of environmental constraints are particularly suited for solution with the hybrid method. Application of the hybrid method is highlighted through two illustrative examples. The first example involves the determination of an optimal flowsheet for the removal of a chemical species from an azeotropic...

    Full Text Available Background. Benign paroxysmal torticollis (BPT is an episodic functional disorder of unknown etiology, characterized by the periods of torticollic posturing of the head, that occurs in the early months of life in healthy children. Case report. We reported two patients with BPT. In the first patient the symptoms were observed at the age of day 20, and disappeared at the age of 3 years. There were 10 episodes, of which 2 were followed by vomiting, pallor, irritability and the abnormal trunk posture. In the second patient, a 12-month-old girl, BPT started from day 15. She had 4 episodes followed by vomiting in the first year. Both girls had the normal psychomotor development. All diagnostical tests were normal. Conclusion. The recognition of BPT, as well as its clinical course may help to avoid not only unnecessary tests and the treatment, but also the anxiety of the parents.

    Full Text Available In this study medical treatment with alpha blocker-prazosin is compared with transurethral resection of prostate (TURP in 62 patients suffering from benign enlargement of prostate with a gland size of less than 20 gms. After thorough interrogation patients were offered either TURP or prazosin therapy. Symptom scoring, residual volume of urine and urinary flow rates were estimated in both the groups before and 3 months after the therapy. 23.5% patients in prazosin group while 90% of patients in TURP group had significant improvement. This distinctly brings out the superiority of TURP for benign enlargement of prostate.

  12. Management of Benign Biliary Strictures

    International Nuclear Information System (INIS)

    Laasch, Hans-Ulrich; Martin, Derrick F.

    2002-01-01

    Benign biliary strictures are most commonly a consequence of injury at laparoscopic cholecystectomy or fibrosis after biliary-enteric anastomosis. These strictures are notoriously difficult to treat and traditionally are managed by resection and fashioning of acholedocho- or hepato-jejunostomy. Promising results are being achieved with newer minimally invasive techniques using endoscopic or percutaneous dilatation and/or stenting and these are likely to play an increasing role in the management. Even low-grade biliary obstruction carries the risks of stone formation, ascending cholangitis and hepatic cirrhosis and it is important to identify and treat this group of patients. There is currently no consensus on which patient should have what type of procedure, and the full range of techniques may not be available in all hospitals. Careful assessment of the risks and likely benefits have to be made on an individual basis. This article reviews the current literature and discusses the options available. The techniques of endoscopic and percutaneous dilatation and stenting are described with evaluation of the likely success and complication rates and compared to the gold standard of biliary-enteric anastomosis

  13. Nocturia and benign prostatic hyperplasia

    Full Text Available Background/Aim. Nocturia often occurs in patients with benign prostate hyperplasia (BPH. The aim of the study was to investigate the frequency of nocturia in patients with BPH. Nocturia and other factors associated with it were also investigated. Methods. Forty patients with the confirmed diagnosis of BPH were studied. Transurethral and transvesical prostatectomy were performed in all the patients. Symptoms were evaluated with the International Prostate Symptom Score before, as well as three and six months after the surgery. All the results were compared with the control group. Results. There was no statistically significant difference between the patients before and after the surgery regarding nocturia. There was, however, a statistically significant difference between the operated patients and the control group regarding nocturia, as well as a statistically significant correlation between noctruia and the age of the patients in both the investigated and the control group. A correlation also existed between nocturia and the prostatic size. Conclusion. There was no statistically significant improvement in symptoms of nocturia after the surgery. It is necessary to be very careful in decision making in patients with nonabsolute indiction for surgery and isolated bothersome symptom of nocturia. Age of a patient should also be considered in the evaluation of favorable result of the surgery because of a significant correlation between noctura and the age of a patient.

    Dizziness is a frequent complaint of patients with Parkinson's disease (PD), and orthostatic hypotension (OH) is often thought to be the cause. We studied whether benign paroxysmal positional vertigo (BPPV) could also be an explanation. To assess the prevalence of benign paroxysmal positional vertigo in patients with Parkinson's disease, with and without dizziness. 305 consecutive outpatients with PD completed the Movement Disorders Society-sponsored revision of the Unified Parkinsons' Disease Rating Scale-motor score, the Dizziness Handicap Inventory, the Dix-Hallpike maneuver and a test for orthostatic hypotension. When positive for benign paroxysmal positional vertigo, a repositioning maneuver was performed. Patients were followed for three months to determine the clinical response. 305 patients responded (186 men (61%), mean age 70.5 years (Standard Deviation 9.5 years)), of whom 151 (49%) complained of dizziness. 57 (38%) of the dizzy patients appeared to have orthostatic hypotension; 12 patients (8%) had a classical but previously unrecognized benign paroxysmal positional vertigo. A further four patients (3%) had a more atypical presentation of benign paroxysmal positional vertigo. Three months after treatment, 11 (92%) of patients with classical benign paroxysmal positional vertigo were almost or completely without complaints. We found no 'hidden' benign paroxysmal positional vertigo among patients without dizziness. The prevalence of benign paroxysmal positional vertigo among all patients with PD was 5.3%. Among Parkinson patients with symptoms of dizziness, up to 11% may have benign paroxysmal positional vertigo, which can be treated easily and successfully. Crown Copyright © 2013.

    The purpose of this study was to explore the budget impact of dutasteride plus tamsulosin fixed-dose combination (DUT + TAM FDC) versus tamsulosin monotherapy, in the treatment of patients with benign prostatic hyperplasia (BPH) from the perspective of the Greek healthcare insurance system. A Microsoft Excel-based model was developed to estimate the financial consequences of adopting DUT + TAM FDC within the Greek healthcare setting. The model, compared six mutually exclusive health states in two alternative treatment options: current standard of care and the introduction of DUT + TAM FDC in the market. The model used clinical inputs from the CombAT study; data on resource use associated with the management of BPH in Greece were derived from expert panel, and unit cost data were derived from official reimbursement tariffs. A payer perspective was taken into account. As patient distribution data between public and private sectors are not available in Greece two scenarios were investigated, considering the whole eligible population in each scenario. A 4 year time horizon was taken into account and included treatment costs, number of transurethral resections of the prostate (TURPs) and acute urinary retention (AUR) episodes avoided. The clinical benefit from the market adoption of DUT + TAM FDC in Greece was 1,758 TURPs and 972 episodes of AUR avoided cumulatively in a four year period. The increase in total costs from the gradual introduction of DUT + TAM FDC to the Greek healthcare system ranges from €1.3 million in the first year to €5.8 million in the fourth year, for the public sector, and €1.2 million to €4.0 million, for the private sector. This represents an increase of 1.91% to 7.94% for the public sector and 1.10% 3.29% in the private sector, during the 4-year time horizon. Budget impact analysis (BIA) results indicated that the gradual introduction of DUT + TAM FDC, would increase the overall budget of the disease, however providing

  16. Plasminogen and angiostatin levels in female benign breast lesions

    2015-10-01

    Full Text Available It is known that benign breast tissue exhibit relatively low angiogenic capacity. Activation of angiogenesis in mammary pre-malignant lesions could be associated with disease progression and high risk of transformation into the breast cancer. However, insight into the underlying molecular mechanisms involved in angiogenesis regulation in non-cancerous breast pathologies is still poorly defined. The purpose of the present study was to determine levels of plasminogen and its proteolytic fragments (angiostatins in mammary dysplasia (mastopathy and breast cyst and benign neoplasms (fibroadenomas. Plasminogen and angiostatins were analyzed using immunoblotting and quantified by densitometric scanning. The significant increase in plasminogen levels was found in fibrocystic, cysts, and non-proliferatious fibroadenoma masses (4.7-, 3.7-, and 3.5-fold, respectively compared to healthy breast tissues (control. In the same benign lesions, 6.7-, 4-, and 3.7-fold increase in plasminogen 50 kDa fragment (angiostatin levels as compared with control were also observed. Activation of matrix metalloproteinase-9, which was detected using gelatine zymography, could be responsible for plasminogen cleavage and abundance of angiostatin in fibrocystic and cyst masses. In contrast, dramatic decrease of both plasminogen and angiostatin levels (3.8- and 5.3-folds, respectively was shown in tissues of proliferatious form of fibroadenoma in comparison with that of the dormant type of this neoplasm. Based on the obtained results, we concluded that angiostatin, a potent vessel growth inhibitor and anti-inflammatory molecule, can play a crucial role in pathophysiology of non-cancerous breast diseases. Further studies are needed to evaluate potential diagnostic and clinical implications of these proteins for prediction and therapy of benign breast pathologies.

  17. Horizontal Canal Benign Positional Vertigo

    Directory of Open Access Journals (Sweden)

    Mohtaram Najafi

    1998-03-01

    Full Text Available Benign paroxysmal positional vertigo (BPPV is a syndrome characterized by transient episodes of vertigo in association with rapid changes in head position in Dix-Halpike Maneuver. This kind of vertigo is thought to be caused by migration of otoconial debris into canals other than the posterior canal, such as the anterior or lateral canals. It is also theoretically possible for many aberrant patterns of BPPV to occur from an interaction of debris in several canals, location of debris within the canal, and central adaptation patterns to lesions. The symptoms of BPPV are much more consistent with free-moving densities (canaliths in the posterior SCC rather than fixed densities attached to the cupula. While the head is upright, the particles sit in the PSC at the most gravity-dependent position. The best method to induce and see vertigo and nystagmus in BPPV of the lateral semicircular canal is to rotate head 90°while patient is in the supine position, nystagmus would appear in the unaffected side weaker but longer than the affected side. canal paresis has been described in one third of the patients with BPPV. Adaptation which is one of the remarkable features of BPPV in PSC is rarely seen in LSC. Rotations of 270° or 360° around the yaw axis (the so-called barbecue maneuver toward the unaffected ear are popular methods for the treatment of geotropic HC-BPPV. These maneuvers consist of sequential head turning of 90° toward the healthy side while supine. With these maneuvers, the free-floating otoconial debris migrates in the ampullofugal direction, finally entering the utricle through the nonampullated end of the horizontal canal. This kind of vertigo recovers spontaneously more rapidly and suddenly.

    Formalin-fixed, paraffin-embedded tissue sections from 26 malignant fibrous histiocytomas (MFH) and 61 benign fibrohistiocytic proliferations (BFHP) were evaluated immunohistochemically. An avidinbiotin-peroxidase technique was used to determine immunoreactivity for alpha-1 antichymotrypsin, muramidase, HLA-DR, leucocyte common antigen, S-100 protein, vimentin, desmin, and keratin. MFHs were consistently positive for ACT and vimentin and inconsistently reactive for the other antigens. MFHs were negative for LCA suggesting a mesenchymal origin for these lesions. In the MFH histologic subtypes, antigen expression was not significantly different to be useful in their classification. Also no distinctive pattern emerged relative to immunoreactivity and tumor location. The benign lesions, giant cell tumor of tendon sheath, dermatofibroma, and oral benign fibrous histiocytoma differed from the MFHs in that they were often LCA positive, suggesting origin from hematopoetic mononuclear-macrophages. The immunoprofiles of peripheral fibromas and "giant cell" fibromas were felt to be consistent with origin from mesenchymal cells. Several of the antigens studied could be used to differentiate the benign lesions studied from other benign neoplasms. The antigens were, however, of little value in separation of benign and malignant lesions.

    Purpose: Given the excellent prognosis for patients with benign meningiomas, treatment strategies to minimize late effects are important. One strategy is proton radiation therapy (RT), which allows less integral dose to normal tissue and greater homogeneity than photon RT. Here, we report the first series of proton stereotactic radiosurgery (SRS) used for the treatment of meningiomas. Methods and Materials: We identified 50 patients with 51 histologically proven or image- defined, presumed-benign meningiomas treated at our institution between 1996 and 2007. Tumors of <4 cm in diameter and located {>=}2 mm from the optic apparatus were eligible for treatment. Indications included primary treatment (n = 32), residual tumor following surgery (n = 8), and recurrent tumor following surgery (n = 10). The median dose delivered was 13 Gray radiobiologic equivalent (Gy[RBE]) (range, 10.0-15.5 Gy[RBE]) prescribed to the 90% isodose line. Results: Median follow-up was 32 months (range, 6-133 months). Magnetic resonance imaging at the most recent follow-up or time of progression revealed 33 meningiomas with stable sizes, 13 meningiomas with decreased size, and 5 meningiomas with increased size. The 3-year actuarial tumor control rate was 94% (95% confidence interval, 77%-98%). Symptoms were improved in 47% (16/ 34) of patients, unchanged in 44% (15/34) of patients, and worse in 9% (3/34) of patients. The rate of potential permanent adverse effects after SRS was 5.9% (3/51 patients). Conclusions: Proton SRS is an effective therapy for small benign meningiomas, with a potentially lower rate of long-term treatment-related morbidity. Longer follow-up is needed to assess durability of tumor control and late effects.

    To examine, using post hoc analysis, the influence of baseline variables on changes in international prostate symptom score (IPSS), maximum urinary flow rate (Qmax ) and IPSS quality of life (QoL) in patients with moderate-to-severe lower urinary tract symptoms (LUTS) due to benign prostatic hyperplasia (BPH) treated with either the α-blocker tamsulosin or the dual 5-alpha reductase inhibitor dutasteride, alone or in combination, as part of the 4-year Combination of Avodart and Tamsulosin (CombAT) study. CombAT was a 4-year, multicentre, randomized, double-blind, parallel-group study in 4844 men ≥50 years of age with a clinical diagnosis of BPH by medical history and physical examination, an IPSS ≥12 points, prostate volume (PV) ≥30 mL, total serum PSA level ≥1.5 ng/mL, and Qmax >5 mL/s and ≤15 mL/s with a minimum voided volume ≥125 mL. Eligible subjects were randomized to receive oral daily tamsulosin, 0.4 mg; dutasteride, 0.5 mg; or a combination of both. Baseline variable subgroups analysed were as follows: PV (30 to tamsulosin were performed from the general linear model with statistical significance defined as P ≤ 0.01. Combination therapy resulted in a significantly greater improvement from baseline IPSS at 48 months vs tamsulosin monotherapy across all baseline subgroups. The benefit of combination therapy over dutasteride was confined to groups with lower baseline PV (tamsulosin but not dutasteride monotherapy. Qmax improvement appeared to increase with PV and PSA level in combination therapy subjects. The proportion of subjects with an IPSS QoL ≤2 (at least mostly satisfied) at 48 months was significantly higher with combination therapy than with dutasteride for subgroups with PV 40-60 mL and PSA level tamsulosin for all PSA subgroups and PV subgroups ≥40 mL. CombAT data support the use of long-term combination therapy with dutasteride and tamsulosin in patients considered at risk for progression of BPH, as determined

    To investigate whether a fixed-dose combination (FDC) of 0.5 mg dutasteride and 0.4 mg tamsulosin is more effective than watchful waiting with protocol-defined initiation of tamsulosin therapy if symptoms did not improve (WW-All) in treatment-naïve men with moderately symptomatic benign prostatic hyperplasia (BPH) at risk of progression. This was a multicentre, randomised, open-label, parallel-group study (NCT01294592) in 742 men with an International Prostate Symptom Score (IPSS) of 8-19, prostate volume ≥30 mL and total serum PSA level of ≥1.5 ng/mL. Patients were randomised to FDC (369 patients) or WW-All (373) and followed for 24 months. All patients were given lifestyle advice. The primary endpoint was symptomatic improvement from baseline to 24 months, measured by the IPSS. Secondary outcomes included BPH clinical progression, impact on quality of life (QoL), and safety. The change in IPSS at 24 months was significantly greater for FDC than WW-All (-5.4 vs -3.6 points, P tamsulosin. FDC therapy with dutasteride and tamsulosin, plus lifestyle advice, resulted in rapid and sustained improvements in men with moderate BPH symptoms at risk of progression with significantly greater symptom and QoL improvements and a significantly reduced risk of BPH progression compared with WW plus initiation of tamsulosin as per protocol. © 2015 The Authors.

    Full Text Available Abstract Introduction We report the case of a patient with a benign multicystic peritoneal mesothelioma and describe its appearance on computed tomography scans and ultrasonography, in correlation with gross clinical and pathological findings. Case presentation A 72-year-old Caucasian woman presented to our emergency department with acute abdomen signs and symptoms. A clinical examination revealed a painful palpable mass in her left abdomen. Abdominal ultrasonography and computed tomography demonstrated the presence of a large cystic mass in her left upper abdomen, adjacent to her left hemidiaphragm. The lower border of the mass extended to the upper margin of her pelvis. A complete resection of the lesion was performed. Pathological analysis showed a benign multicystic peritoneal mesothelioma. Conclusions Benign multicystic peritoneal mesothelioma is a rare lesion with a non-specific appearance on imaging. Its diagnosis always requires pathological analysis.

    Objective was to characterize benign breast diseases in Eastern Nigeria and to highlight the age variations of these lesions as base line data. The Department of Morbid Anatomy, University of Nigeria Teaching Hospital, Enugu caters for over 30 million African blacks and receives 2000 surgical pathology specimens yearly. Seven hundred and twenty-two benign breast specimens were analyzed over 5 years from Ist January 2000 to 31 December 2004, out of 1050 breast samples received. Of 1050 breast specimens received, 722 (68.8%) were benign. Fibroadenoma was the most common lesion with 318 cases (44%), occurring at a mean age of 16-32 years. Next were fibrocystic changes with 165 cases (22.9%) at a mean age of 23-45 years. Normal breast in the axillary tail region was seen in 32 cases (4.4%), represented as no pathology, with a mean presentation age of 20-46 years. Low grade Phyllodes tumor had 28 cases (3.9%), presenting at an average mean age of 17-32 years. Lactating adenoma had 19 (2.6%) cases. Other lesions made up less than 3% each. Benign breast lesions peaked at the 20-24 age range and then declined. Most were females. Benign breast lesions occur more frequently than malignant breast lesions with a ratio of 2.3:1 and were presented 20 years earlier than their malignant counterparts. Fibroadenoma was the most common benign lesions followed by fibrocystic disease, similar to the findings in Western Nigeria. In Northern Nigeria, fibrocystic breast disease was more common. (author)

    Hysterectomy is one of the most common gynaecological surgical procedures performed but there appears to be a decline in the performance of this procedure in Ireland in recent times. We set out to establish the extent of the decline of hysterectomy and to explore possible explanations. Data for hysterectomy for benign disease from Ireland was obtained from the Hospital In-Patient Enquiry Scheme (HIPE) section of the Economic and Social Research Institute for the years 1999 to 2006. The total number of hysterectomies performed for benign disease showed a consistent decline during this time. There was a 36% reduction in the number of abdominal hysterectomy procedures performed.

    2013-07-01

    A 68 year old male patient presented for radiation therapy for treatment of a benign tumor, a glioma of his left optic nerve. The radiation oncologist intended to prescribe 52.2 Gy to the planning target volume, while maintaining a maximum of 54 Gy to the optic nerves and the optic chiasm and a maximum of 40–45 Gy to the globes in order to minimize the possibility of damaging the optic system, which is especially important as this is a benign tumor. The dosimetrist devised a conformal non-coplanar three-dimensional plan with a slightly weighted forward planning component. This plan was created in approximately 15 minutes after the critical organs and the targets were delineated and resulted in an extremely conformal and homogenous plan, treating the target while sparing the nearby critical structures. This approach can also be extended to other tumors in the brain - benign or malignant.

  19. Benign prostatic hyperplasia: clinical treatment can complicate cataract surgery

    2010-10-01

    Full Text Available PURPOSE: To investigate the effects of alpha-1 adrenergic receptor antagonists for the treatment of benign prostatic hyperplasia (BPH regarding potential risks of complications in the setting of cataract surgery. AIM: To address recommendations, optimal control therapy, voiding symptoms and safety within the setting of cataract surgery. MATERIALS AND METHODS: A comprehensive literature review was performed using MEDLINE with MeSH terms and keywords "benign prostatic hyperplasia", "intraoperative floppy iris syndrome", "adrenergic alpha-antagonist" and "cataract surgery". In addition, reference lists from identified publications were reviewed to identify reports and studies of interest from 2001 to 2009. RESULTS: The first report of intraoperative floppy iris syndrome (IFIS was observed during cataract surgery in patients taking systemic alpha-1 AR antagonists in 2005. It has been most commonly seen related to use of tamsulosin. Changes of medication and washout periods of up to 2 weeks have been attempted to reduce the risk of complications in the setting of cataract surgery. CONCLUSION: Patients under clinical treatment for BPH should be informed about potential risks of this drug class so that it can be discuss with their healthcare providers, in particular urologist and ophthalmologist, prior to cataract surgery.

    Benign paroxysmal positional vertigo is a common labyrinthine disorder caused by a mechanic stimulation of the vestibular receptors within the semicircular canals. It is characterized by positional vertigo and positional nystagmus, both provoked by changes in the position of the head with respect to gravity. The social impact of the disease and its direct and indirect costs to healthcare systems are significant owing to impairment of daily activities and increased risk of falls. The first description of a patient with benign paroxysmal positional vertigo is from Robert Bárány in 1921, but the features of the syndrome and the diagnostic maneuver were well described by Dix and Hallpike in 1952. Since then, the gradually increasing interest of otolaryngologists and neurologists has led to a progressive advance in the knowledge of this labyrinthine disorder with regard to its epidemiologic, pathophysiologic, clinical, and therapeutic aspects. Despite the often effective diagnosis and treatment of most cases of benign paroxysmal positional vertigo, the physiopathologic explanations of the disease are mainly speculative. In this chapter, we describe the epidemiologic, pathophysiologic, clinical, and therapeutic aspects of benign paroxysmal positional vertigo. © 2016 Elsevier B.V. All rights reserved.

    Benign prostatic hyperplasia (BPH) and prostate cancer are among the most common diseases of the prostate gland and represent significant burdens for patients and health-care systems in many countries. The two diseases share traits such as hormone-dependent growth and response to antiandrogen...... therapy. Furthermore, risk factors such as prostate inflammation and metabolic disruption have key roles in the development of both diseases. Despite these commonalities, BPH and prostate cancer exhibit important differences in terms of histology and localization. Although large-scale epidemiological...... studies have shown that men with BPH have an increased risk of prostate cancer and prostate-cancer-related mortality, it remains unclear whether this association reflects a causal link, shared risk factors or pathophysiological mechanisms, or detection bias upon statistical analysis.

    In general, there has been a reluctance on the part of radiation oncologists to undertake the responsibilities of treatment of patients with malignant and benign diseases involving the eye and periorbital tissues. With the changing technologies in diagnosis, alternative modalities for treatment as well as the significant impact of computed tomography and magnetic imaging technologies in the management of patients with eye tumors, there has been a resurgence of interest in treating not only malignant but benign ocular diseases. The refresher course will deal with the latest developments in the diagnosis and therapy of retinoblastomas, uveal melanomas, and malignant lymphomas with emphasis on optimization dosimetry as well as treatment planning along with presentation of the utilization of radioactive eye plaques in management of malignant tumors of the eye. The effects and side effects of radiation therapy will be discussed with emphasis on electron beam, photon beam, and plaque irradiation as well as proton beam irradiation of eye diseases with emphasis on minimization of those side effects. The resurgence of interest in treating benign diseases in the eye will be covered with emphasis on the treatment of the wet type of age related macular degeneration. Finally, the course will also cover radiotherapy for other benign conditions such as pterygium, choroidal and retinal hemangiomas

    Radiotherapy was earlier a method of choice for treatment of benign bleeding disorders (metropathia), especially in woman of high surgical risk. During the period 1912 to 1977 933 women with benign bleeding disorders were treated at Radiumhemmet with intracavitary brachytherapy or external irradiation or a combination of both. The result with regard to cure of the uterine bleedings was good (48%). Hormonal withdrawal symptoms after treatment were noted in 45% of the patients. In the long term follow up an increased risk of cardiovascular death was found in women treated before menopause. Malignant tumours occurred in 107 cases versus 90.2 expected. The estimated ovarian dose of ionizing radiation varied from 3.5 Gy to 6.0 Gy for the three standard techniques. Two women gave birth to a healthy child 4 and 5 years after intracavitary radium treatment. The estimated absorbed dose to the ovaries in these two women were 1 Gy and 4 Gy, respectively

    There is a paucity of data on the spectrum of benign gastric outlet obstruction in India. Our aim was to evaluate its spectrum and to identify the subgroup which would be most amenable to endoscopic therapy. We studied 64 patients whose aetiology revealed in approximately equal proportions: corrosive injury; gastroduodenal tuberculosis (TB); and peptic ulcer disease. The median number of endoscopic dilations required was two for TB, four for peptic ulcer disease and five for corrosive injury. Gastroduodenal TB and corrosive injury appear now to be more, or at least as, common as peptic ulcer disease as causes of benign gastric outlet obstruction in India. Gastroduodenal TB responds best to endoscopic therapy. © The Author(s) 2016.

    2010-05-15

    We present our initial experience with a new biodegradable (BD) esophageal stent in two patients, one for a therapy-resistant benign esophageal stricture, and the other as a temporary measure during curative radiotherapy for oesophageal carcinoma. The BD stents need to be loaded into a conventional pull-back delivery system but are then placed in a standard fashion. Pre-dilatation should be avoided to reduce the risk of migration, however if migration occurs the stents can be left to dissolve in the stomach. The stents are radiolucent but easily identified on CT with minimal artefact and thus might even aid with radiotherapy planning. BD stents offer an exciting new strategy for therapy-resistant benign strictures as well as a supportive measure for oesophageal cancer undergoing non-surgical treatment. (orig.)

    Purpose: To evaluate long-term results of treatment of benign bile duct strictures. Materials and methods: From February 1994 to November 2005, 21 patients (9 men, 12 women) with median age of 50.6 years (range 27-77 years) were indicated to percutaneous treatment of benign bile duct stricture. Stricture of hepatic ducts junction resulting from thermic injury during laparoscopic cholecystectomy was indication for treatment in one patient, stricture of hepaticojejunostomy was indication for treatment in all other patients. Clinical symptoms (obstructive jaundice, anicteric cholestasis, cholangitis or biliary cirrhosis) have appeared from 3 months to 12 years after surgery. Results: Initial internal/external biliary drainage was successful in 20 patients out of 21. These 20 patients after successful initial drainage were treated by balloon dilatation and long-term internal/external drainage. Sixteen patients were symptoms free during the follow-up. The relapse of clinical symptoms has appeared in four patients 9, 12, 14 and 24 months after treatment. One year primary clinical success rate of treatment for benign bile duct stricture was 94%. Additional two patients are symptoms free after redilatation (15 and 45 months). One patient is still in treatment, one patient died during secondary treatment period without interrelation with biliary intervention. The secondary clinical success rate is 100%. Conclusion: Benign bile duct strictures of hepatic ducts junction or biliary-enteric anastomosis are difficult to treat surgically and endoscopically inaccessible. Percutaneous treatment by balloon dilatation and long-term internal/external drainage is feasible in the majority of these patients. It is minimally invasive, safe and effective.

Results: Initial internal/external biliary drainage was successful in 20 patients out of 21. These 20 patients after successful initial drainage were treated by balloon dilatation and long-term internal/external drainage. Sixteen patients were symptoms free during the follow-up. The relapse of clinical symptoms has appeared in four patients 9, 12, 14 and 24 months after treatment. One year primary clinical success rate of treatment for benign bile duct stricture was 94%. Additional two patients are symptoms free after redilatation (15 and 45 months). One patient is still in treatment, one patient died during secondary treatment period without interrelation with biliary intervention. The secondary clinical success rate is 100%. Conclusion: Benign bile duct strictures of hepatic ducts junction or biliary-enteric anastomosis are difficult to treat surgically and endoscopically inaccessible. Percutaneous treatment by balloon dilatation and long-term internal/external drainage is feasible in the majority of these patients. It is minimally invasive, safe and effective

    We report a case of a female with hemihypertrophy, who developed five recurrences of pheochromocytomas until the age of 35. Timely follow-up of the patient's blood pressure assisted in early diagnosis and treatment of recurrent tumors. Recurrent benign pheochromocytomas should raise suspicion of a genetic syndrome.A pheochromocytoma at a young age has a high propensity to recur and strict follow-up is mandatory.

    Prostatic diseases are extremely common, especially in older men. Amongst them, benign prostatic hypertrophy may affect significantly the quality of life of patients by the symptoms it causes. It requires appropriate care. Prostate cancer is the second most common cancer in men after lung cancer and the fifth leading cause of cancer deaths in the world. It affects preferentially older men. An oncogeriatric approach is required for personalised care.

    Full Text Available Pseudoepitheliomatous hyperplasia is an extremely rare condition presenting as a lesion on the glans penis in older men. Physical exam without biopsy cannot differentiate malignant from nonmalignant growth. We report a case of large penile mass in an elderly male with a history of lichen sclerosis, highly suspicious for malignancy. Subsequent surgical removal and biopsy demonstrated pseudoepitheliomatous hyperplasia, an unusual benign histopathologic diagnosis with unclear prognosis. We review the literature and discuss options for treatment and surveillance.

    Full Text Available Introduction: Benign eyelid lesions are classified to infectious, inflammatory and tumoral lesions. The various number of these lesions is due to unique eyelid anatomical structure. Some lesions are simple and do not need any treatment but sometimes patients refer to ophthalmologists due to beauty or problems such as pain, swelling. The aim of our study is to investigate and compare the relative frequency of benign eyelid lesions in Shahid Sadoughi eye clinic as well as the private offices. Methods: This cross sectional six month study was done on 247 patients who referred to Shahid Sadoughi eye clinic and the private offices in 2011. They were examined by direct observation and slit lamp regardless of the cause. The information was gleaned by a questionnaire and the research data was analyzed by SPSS (ver.16. Results: we studied 247 patients including 84(34% male and 163(6% female. The mean age of the patients was 42.7 years. 60.2% of lesions were in upper lid and 39.8% were in lower lid. 51.2% of lesions were in right eye and 48.8% were in left eye. The most common eyelid lesions were papilloma (32.9% nevus (21.9% and chalazion (14.1% respectively. Conclusion: Papilloma, nevus and chalazion are respectively the most common lesion in men and women. Benign lesions were more common in women located more in upper lid, though there was no statistically difference between right and left lid.

    Full Text Available Abstract Introduction Benign gastro-colic fistula is a rare occurrence in modern surgery due to the progress in medical management of gastric ulcer disease. Here we report the first case of benign gastro-colic fistula occurring whilst on proton-pump inhibitor therapy. This is a case study of benign gastro-colic fistula and review of the available literature in regards to etiology, diagnosis, management and prognosis. Case presentation An 84-year-old woman of Caucasian background presented with 12 months of worsening abdominal pain, nausea, vomiting, diarrhea and weight loss on a background of known gastric ulcer disease. Conclusion The leading cause of gastro-colic fistulae has changed from benign to malignant due to improved medical management of gastric ulcer disease. The rarity and non-specific symptoms of gastro-colic fistula make the diagnosis difficult and it is best made by barium enema; however, computed tomography has not been formally evaluated. Surgical management with en bloc resection of the fistula tract is the preferred treatment. Benign gastro-colic fistulae are becoming exceedingly rare in the context of modern medical management of gastric ulcer disease. Surgical management is the gold standard for both benign and malignant disease.

  10. Epidermal growth factor receptor gene status by fluorescence in situ hybridization in malignant, atypical, and benign hidradenomas.

    2010-08-01

    Epidermal growth factor receptor (EGFR) protein overexpression and gene amplification are important prognostic factors in various tumors and EGFR inhibitors are now available as promising chemotherapeutic agents. There is little information in the literature regarding the EGFR protein and gene status in hidradenocarcinomas which has an aggressive biologic course characterized by repeated local recurrences and systemic metastasis. We have previously reported EGFR protein overexpression in malignant, atypical, and benign hidradenomas and would like to further evaluate their gene status by fluorescence in situ hybridization. Fluorescence in situ hybridization by 2-color probe Vysis LSI EGFR SpectrumOrange/CEP 7 SpectrumGreen Probe (Abbott Molecular) and EGFR immunostain (H11, Dakocytomation) were performed in 15 malignant, 15 atypical, and 7 benign hidradenomas. High polysomy and low trisomy was noted in 1 and 4 hidradenocarcinoma, respectively; however, EGFR overexpression was seen only in 1 low trisomy case. Disomy is noted in the remaining 29 cases (9 hidradenocarcinomas, 15 atypical hidradenomas, and 5 benign hidradenomas). EGFR overexpression was seen in 3/12 (25%) malignant hidradenomas, 7/15 (47%) atypical hidradenomas, and 3/5 (60%) benign hidradenomas; none of these cases demonstrated EGFR gene amplification. Polysomy/trisomy is more frequently seen in hidradenocarcinoma than atypical and benign hidradenomas. The role of EGFR inhibitor therapy in hidradenocarcinoma cases with protein overexpression remains unclear. Lack of correlation between the protein expression and polysomy/gene amplification suggests that molecular mechanisms other than gene amplification play a role in EGFR overexpression in malignant, atypical, and benign hidradenomas.

    2012-01-01

    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

    To analyze the clinical effect of tamsulosin and Solifenacin in the treatment of benign prostatic hyperplasia in combination with overactive bladder and its safety. Another objective was to investigate the clinical effect and safety of mega dose of tamsulosin in the treatment of benign prostatic hyperplasia in combination with overactive bladder. One hundred and twenty-four patients who were admitted to the Dept. of Urology at Binzhou People's Hospital, , China with confirmed benign prostatic hyperplasia (BPH) with overactive bladder were randomly divided into two groups. Sixty-two patients in the control group were treated with tamsulosin, while sixty-two patients in the observation group were treated with tamsulosin in combination with solifenacin. The treatment of both groups lasted for 12 weeks. The effect and adverse reaction were compared between the two groups. The international prostate symptom score (IPSS), quality of life (QOL), and overactive bladder symptom score (OABSS), Q max , pulmonary vascular resistance (PVR), daytime urination frequency, urgent urination frequency, urge urinary incontinence frequency and night urinary frequency of both groups improved after treatment, and the difference had statistical significance (P0.05). Treating benign prostatic hyperplasia in combination with overactive bladder with tamsulosin in combination with solifenacin is more effective than tamsulosin, without significantly increasing adverse reactions. Thus the therapy is worth clinical promotion.

  14. What do we know about phytotherapy of benign prostatic hyperplasia?

    Allkanjari, Olta; Vitalone, Annabella

    2015-04-01

    Benign prostatic hyperplasia (BPH) is one of the most common urological diseases in aging men. Because of its long latency, BPH is a good target for prevention. The aim of the study has been to review the various options of treatment, currently available, in the field of phytotherapy. Watchful waiting, pharmacological therapy, and surgery are also helpful, depending on the severity of the disease. Although drug therapy (alpha1-blockers, 5alpha-reductase inhibitors) and surgery (prostatectomy, transurethral resection, etc.) seem to be most effective for patients with moderate-severe BPH, herbal medicines (i.e., Serenoa repens, Pygeum africanum, Urtica dioica) are also commonly used in patients with mild-moderate symptoms. On the basis of preclinical studies several mechanisms of action have been postulated, including 5alpha-reductase inhibition, alpha-adrenergic antagonism, dihydrotestosterone and estrogen receptor inhibition. Randomized clinical trials indicate significant efficacy in improving urinary symptoms and mild adverse effects for some phytotherapeutic agents, while further clinical evidence is needed for others (e.g., Epilobium spp., Secale cereale, Roystonea regia). Healthcare professionals should be constantly informed about BPH phytotherapy, taking into account the risk/benefit profile of the use of medicinal plants in the management of BPH.

    Full Text Available Ureteritis cystica is an uncommon benign pathology of the ureter. The etiology is unclear but the diagnosis has become much easier to make with the routine use of ureteroscopy for diagnosis of ureteric lesions. We present a case of a 63 year old Sudanese woman with a history of repeated attacks of right loin pain in whom magnetic resonance urography (MRU showed multiple filling defects in the right ureter. These were initially thought to be malignant urothelial lesions. Ureteroscopy revealed cystic smooth walled masses which discharged tiny turbid fluid on biopsy. An intraoperative diagnosis of ureteritis cystica was confirmed. The patient was managed conservatively.

    1983-01-01

    Differential diagnosis of benign intrahepatic tumours can be very difficult despite numerous non-invasive diagnostic approaches, as is evident from two case reports presented here. The problem appears particularly intricate if two or more masses or space-occupying growths are present at the same time, the diagnostic aspects being different. In the first case, echinococcus alveolaris occurred simultaneously with a cavernous haemangioma and a focal nodular hyperplasia (FNH). In the second case, FNH as a pendulating tumour was combined with a second focus in the superior part of the liver. These two examples are used as basis for discussing various diagnostic approaches, such as sonography, computed tomography and scintiscanning.

    Nuclear medicine therapy uses unsealed radioactive sources for the selective delivery of radiation to tumours or target organs. For benign disorders such as thyrotoxicosis and arthritis radionuclide therapy provides an alternative to surgery or medical treatment. In cancer treatment, it often combines the advantage of target selectivity (like brachytherapy or external beam radiotherapy) with that of being systemic, as with chemotherapy, and it may be used as part of a therapeutic strategy with curative intent or for disease control and palliation. Toxicity is generally limited to the haematopoietic tissue and few side-effects are observed. When cure is feasible, the long-term consequences of radionuclide therapy (eg, fertility disorders and leukaemia or other secondary cancers) do compare favourably with the risks associated with and accepted for chemotherapy and radiotherapy.

    Surgical management of thyroid diseases (BTDs) has been a topic of interest and confusion for many years. Almost 80% of thyroidectomies at an average endocrine surgical unit are carried out for BTDs.Resistance to surgical intervention in BTDs has been based on the belief that increased complication rate is inherent in its use, this is despite thepotential advatages in terms of confirming the benign nature of the lesion, controlling the disease, and relieving of local symptoms of large neck mass. Benign thyroid diseases are more likely to occur in middle-aged woman living in iodine deficient areas, or have a family history of goiter, or in patients taking iodine-containig drugs, like amoidarone, or in patients with previous history of x-ray exposure. However, the physician must be carefull in making the diagnosis of BTDsin patients of extremes of age or in presence of positive history of radiation, or in patients with family history of thyroid or colon cancer . In this atricle we will review the etiology,epidemiology , diagonastic methodologiesand the recent trends in the sugical and medical mangement of BTDs. (author)

    Full Text Available Case summary A 10-year-old castrated male domestic shorthair cat was presented for assessment of a gingival mass surrounding the left maxillary third and fourth premolar teeth. The mass was surgically removed by means of a marginal rim excision, and the tissue was submitted for histological assessment. It was identified as a benign cementoblastoma (true cementoma. There was proliferation of mineralized eosinophilic material with multiple irregularly placed lacunae and reversal lines, reminiscent of cementum. The cat recovered uneventfully from the anesthesia, and there was no evidence of tumor recurrence 6 months after surgery. Relevance and novel information Cementoblastomas (true cementomas in domestic animals are rare, with just a few reports in ruminants, monogastric herbivores and rodents. Cementoblastoma is considered a benign tumor that arises from the tooth root. The slow, expansive and constant growth that characterizes these masses may be accompanied by signs of oral discomfort and dysphagia. This case report is intended to increase knowledge regarding this tumor in cats and also highlights the importance of complete excision of the neoplasm. To our knowledge, there are no previous reports in the literature of cementoblastoma in the cat.

    Benign prostatic hyperplasia (BPH) is arguably the most common benign disease of mankind. As men age, the prostate inexorably grows often causing troubling symptoms causing them to seek out care. While traditionally treated by transurethral resection or open surgical removal of the hypertrophied adenoma, today the urologist has numerous medical, surgical and minimally invasive techniques available. In this supplement The Canadian Journal of Urology provides a review of the various techniques and medications available today. As an introduction to the supplement, the aim of this article is to review the epidemiology and economy of BPH as well as its natural history and diagnosis. A systematic review of available literature was looking for articles on BPH and its epidemiology, economics, natural history and management using PubMed database. The prevalence of this condition is increasing with the population aging and so does the economic burden. The exact etiology of this condition is unknown, but some risk factors have been identified. The diagnostic and treatment of this very common disease should rely on a strong collaboration between primary care physician and urologist. There are multiple options in treating BPH including medical, surgical and newer minimally invasive options. The challenge with having a variety of options is to review them with the patient and help the patient select the best treatment option for their condition.

    The purpose of this study is to evaluate the accuracy of differentiation between benign and malignant clustered microcalcifications without mass on mammogram. Fourty six mammograms of 44 patients showing clustered microcalcifications without mass were interpreted blindly by five independent observers majoring in breast imaging from different institutions. Twenty two were malignant (10 infiltrating ductal carcinomas, 12 intraductal carcinomas) and 24 were benign (all fibrocystic disease). The observers judge benignancy or malignancy of microcalcifications. The authors assess the accuracy of differential diagnosis of clustered microcalcifications. Of 24 cases proved benign microcalcifications, five radiologists correctly interpreted 20 on average as benign and of malignant 22 cases, 16 on average were correctly interpreted as malignant. The diagnostic accuracy of malignant microcalcifications was 71.8% on average(63.6%{approx}81.8%) and the diagnostic accuracy for benign microcalcifications was 83% on average(71%{approx}92%). It was 9 among total 46 cases that were misinterpreted by more than three radiologists. Among these 9 cases, malignant microcalcifications that had been misinterpreted as benign were seven, benign microcalcifications misinterpreted as malignant were two. The diagnostic accuracy of clustered malignant microcalcifications(71.8%) without mass on mammogram was lower than that of benign microcalcifications(83.3%). So, in case of suspected malignant microcalcification on mammogram, it is preferable that along with magnification view, histopathologic confirmation by core biopsy must be obtained.

Silodosin, (--1-(3-hydroxypropyl-5-[(2R-2-({2-[2-(2,2,2trifluoroethoxy phenoxy]ethyl}aminopropyl]-2,3-dihydro-1H-indole-7- carboxamide, is a new α1A-AR selective antagonist. Silodosin is highly selective for the α1A-AR subtype, showing an affinity for the α1A-AR that is 583- and 55.5-fold higher than its affinity for the α1B- and α1D-ARs, respectively. In randomized, double-blind, placebo-controlled phase III studies performed in Japan and the United States, silodosin has been shown to be effective for both storage and voiding symptoms associated with benign prostatic hyperplasia. Early effects of silodosin (after 2–6 hours or day 1 on lower urinary tract symptoms have also been reported. In urodynamic studies, detrusor overactivity disappeared in 40% and improved in 35% of patients after administration. In pressure flow studies, the grade of obstruction on the International Continence Society nomogram showed improvement in 56% of patients. The rate of adverse events in the silodosin, tamsulosin and placebo groups was 88.6%, 82.3%, and 71.6%, respectively. The most common adverse event was (mostly mild abnormal ejaculation (28.1%. However, few patients (2.8% discontinued silodosin because of abnormal ejaculation. Orthostatic hypotension showed a similar incidence in the silodosin (2.6% and placebo (1.5% groups. In conclusion, silodosin improves detrusor overactivity and obstruction and thus may be effective for both storage and voiding

    Full Text Available BACKGROUND Benign Paroxysmal Positional Vertigo (BPPV is one of the most common disorders of the vestibular system, which maybe unilateral or involve both labyrinths. It can be effectively treated by Canalith Repositioning Manoeuvers (CRM, but lack of awareness leads to delay in effective treatment. MATERIALS AND METHODS Study was conducted in a tertiary care center where 184 patients with BPPV were subjected to positional test and CRM. RESULTS M:F ratio was 1:2.1. 85% of BPPV patients were relieved of symptoms with one sitting of CRM. CONCLUSION CRM is very effective in treatment of BPPV. General practitioners and specialists should be more educated about this condition, which will reduce the delay in correct diagnosis and proper treatment.

    To determine the prevalence of comorbid disease in patients with benign paroxysmal positional vertigo (BPPV) and the relationship of comorbid disease to symptoms of vertigo, disequilibrium, and anxiety. Patients who had posterior semicircular canal BPPV and who had been referred for vestibular rehabilitation at a tertiary care center completed a health status questionnaire and the Vertigo Symptom Scale, answered questions about level of vertigo, and were tested on computerized dynamic posturography. Subjects had high rates of diabetes, mild head trauma, and probable sinus disease. Balance was generally impaired, worse in diabetics and subjects with significant vestibular weakness. Subjects who smoked or had had mild head trauma had higher levels of anxiety. Comorbid conditions, particularly diabetes, mild head trauma, and sinus disease, are unusually prevalent in BPPV patients. Message: Patients with comorbid disease are at risk for having increased vertigo, anxiety, and disequilibrium compared to other patients. Copyright 2004 S. Karger AG, Basel

    2014-05-01

    The debate over the role of the da Vinci surgical robotic platform in benign gynecology is raging with increasing fervor and, as product liability issues arise, greater financial stakes. Although the best currently available science suggests that, in the hands of experts, robotics offers little in surgical advantage over laparoscopy, at increased expense, the observed decrease in laparotomy for hysterectomy is almost certainly, at least in part, attributable to the availability of the robot. In this author's opinion, the issue is not whether the robot has any role but rather to define the role in an institutional environment that also supports the safe use of vaginal and laparoscopic approaches in an integrated minimally invasive surgery program. Programs engaging robotic surgery should have a clear and self-determined regulatory process and should resist pressures in place that may preferentially support robotics over other forms of minimally invasive surgery.

    2015-04-01

    Benign paroxysmal positional vertigo (BPPV) presentations are unique opportunities to simultaneously improve the effectiveness and efficiency of care. The test and treatment for BPPV--the Dix-Hallpike test (DHT) and the canalith repositioning maneuver (CRM), respectively--are supported by two evidence-based guidelines (American Academy of Otolaryngology--Head and Neck Surgery and American Academy of Neurology). With these processes, patients can be readily identified and treated at the bedside, quickly and without expensive tests. Patients randomized to the CRM have a cure rate of 80% at 24 h, compared to only 10% of controls. Despite this large effect size, less than 10% of affected patients receive the treatment, which shows that the management of BPPV in routine care is suboptimal. Future research is necessary to disseminate and implement the DHT and the CRM into routine practice. © 2015 New York Academy of Sciences.

    The pathogenesis of benign prostate hyperplasia (BPH) is still unclear. It is a common disease affecting exclusively humans in its full clinical appearance. There is a broad variety of possible underlying mechanisms which most likely interact in the pathogenesis of the disease: inflammatory processes taking place predominantly in the stroma and inducing proliferation of all tissues within the transitional zone, an imbalance of androgens and estrogens and their receptors, hyperinsulinemia and hypercholesterolemia (metabolic syndrome) as direct promoters of glandular growth and autosomal dominant inheritance. The detrusor muscle responds to the increased outflow resistance with muscular hypertrophy. Decreased compliance of the bladder wall results in voiding difficulties while electric instability of the hypertrophied detrusor muscle and increased recruiting of otherwise silent afferent fibres cause storage symptoms.

    Osteoblastoma is categorized as a benign bone-forming tumor, which occurs rarely in the craniofacial region. We report a case of osteoblastoma developed in the nasal cavity and ethmoid sinus in a 14-year-old girl whose chief symptom was nasal obstruction and exophthalmos on the right side. CT revealed the lesion having the same density as bone and a ground-glass border, expanding to the nasal and paranasal cavities. Complete removal was accomplished under endoscopic view, although the tumor was removed piece by piece. Histologic inspection showed exuberant osteoid trabeculae and immature bone formation by osteoblasts with vascularized connective tissue. We diagnosed the tumor as osteoblastoma based on the clinical presentation and the size of the tumor. No recurrence was evident at the 1-year follow-up visit. Copyright © 2012 Elsevier Ireland Ltd.

    Full Text Available Introduction. Mature teratomas (benign cystic teratomas or dermoid cysts are among the most common ovarian tumours; however, teratomas of the omentum and mesentery are extremely rare. Teratoma in the intraperitoneal cavity is uncommon and atypical, and it is even more uncommon in adulthood. Case Outline. An 82-year-old female was admitted to our department with clinical signs of abdominal tumour. The ultrasound scan and preoperative laboratory tests were done. Explorative laparotomy revealed tumour with torsion on its pedicle at the greater omentum. After removal of the mass and the incision a tooth and hair were found, characteristics of teratoma. Conclusion. The excision was very effective and also definitive treatment for this case. The patient recovered well and was discharged 3 days later. The patient probably carried the tumour all her life asymptomatically until admission.

  17. Insights from radiation treatment for benign disease

    This note compares mortality figures for patients treated with low dose ionizing radiation for benign conditions between the 1920's and 1950's with figures available from the Japanese A-bomb survivors. X radiation for ringworm, ankylosing spondylitis and post-partum mastitis are considered. Figures for leukemia are roughly comparable between radiotherapy groups and A-bomb survivors. Figures for the increased relative risk of breast cancer in spondylitis patients were in marked contrast to bomb survivors who received comparable doses, but compatible with the increase among women given x-rays for acute post-partum mastitis in the 1940's and 1950's. This study also suggests the possibility of different time patterns of risk between different cancers. (U.K.).

    Considering that there are some studies with autopsies from AIDS describing only malignant neoplasias and that changes can occur after the introduction of Highly Active Antiretroviral Therapy (HAART), our objectives were to analyze the frequency of benign and malignant neoplasms in AIDS patients in the periods of both pre- and post-HAART. This is a retrospective study with 261 autopsies of HIV-positive patients between 1989 and 2008 in Uberaba, Brazil. Sixty-six neoplasms were found (39 benign, 21 malignant and six premalignant) in 58 patients. The most frequent malignant neoplasms were lymphoid, in 2.7% (four Non-Hodgkin lymphoma, one Hodgkin, one multiple myeloma and one plasmablastic plasmacytoma), and Kaposi's Sarcoma, in 2.3% (six cases). The most frequent benign neoplasms were hepatic hemangiomas in 11 (4.2%) of 261 cases and uterine leiomyoma in 11 (15.7%) of 70 woman. In the pre-HAART period eight (9.8%) benign neoplasias and four (4.9%) malignant occurred in 82 patients; in the post-HAART period, 29 (16.2%) benign and 17 (9.5%) malignant were present; however, the differences were not significant. We conclude that the introduction of HAART in our region doesn't look to have modified the frequency of neoplasms occurring in patients with HIV.

  19. Basics of Radiation Biology When Treating Hyperproliferative Benign Diseases

    Directory of Open Access Journals (Sweden)

    Franz Rödel

    2017-05-01

    Full Text Available For decades, low- and moderate-dose radiation therapy (RT has been shown to exert a beneficial therapeutic effect in a multitude of non-malignant conditions including painful degenerative muscoloskeletal and hyperproliferative disorders. Dupuytren and Ledderhose diseases are benign fibroproliferative diseases of the hand/foot with fibrotic nodules and fascial cords, which determine debilitating contractures and deformities of fingers/toes, while keloids are exuberant scar formations following burn damage, surgery, and trauma. Although RT has become an established and effective option in the management of these diseases, experimental studies to illustrate cellular composites and factors involved remain to be elucidated. More recent findings, however, indicate the involvement of radiation-sensitive targets like mitotic fibroblasts/myofibroblasts as well as inflammatory cells. Radiation-related molecular mechanisms affecting these target cells include the production of free radicals to hamper proliferative activity and interference with growth factors and cytokines. Moreover, an impairment of activated immune cells involved in both myofibroblast proliferative and inflammatory processes may further contribute to the clinical effects. We here aim at briefly describing mechanisms contributing to a modulation of proliferative and inflammatory processes and to summarize current concepts of treating hyperproliferative diseases by low and moderate doses of ionizing radiation.

    Benign focal epilepsy with affective symptoms (BFEAS) is a rare childhood epilepsy syndrome essentially characterized by "epileptic attacks with affective symptoms of a terrifying type". Since the original description, approximately 50 cases have been reported. To our knowledge, however, none of the studies included video-EEG data. Herein, we detail the electroclinical features of a neurodevelopmentally normal 9-year-old boy with epilepsy since the age of 2 years. His seizure semiology essentially consisted of nocturnal focal seizures featuring abrupt fear and autonomic phenomena (such as excessive sweating, repeated swallowing, and coughing), associated with impaired consciousness. These seizures were often secondary generalized, and he had multiple episodes of convulsive status epilepticus. He has been seizure-free for the past year and a half on dual antiepileptic therapy with sulthiamine and valproate. His intellectual and social abilities are excellent (IQ of 116), although he does have difficulties particularly in language learning, and was recently diagnosed with phonological dyslexia with dysorthography. By presenting our patient's history and video-EEG, we intend to further detail the semiology of seizures with affective symptomatology. [Published with video sequence on www.epilepticdisorders.com].

  1. Metabolic syndrome and benign prostatic hyperplasia: An update

    Directory of Open Access Journals (Sweden)

    Ho-Yin Ngai

    2017-07-01

    Full Text Available Metabolic syndrome (MetS is a cluster of metabolic abnormalities related to central adiposity and insulin resistance. Its importance is increasingly recognized as it associates with increased risks of metabolic and cardiovascular diseases. These metabolic aberrations of MetS may lead to development of benign prostatic hyperplasia (BPH and lower urinary tract symptoms (LUTS in men. A 26.5%–55.6% prevalence of MetS in men with LUTS was reported in worldwide studies. Although the exact biological pathway is not clear yet, insulin resistance, increased visceral adiposity, sex hormone alterations and cellular inflammatory reactions played significant roles in the related pathophysiological processes. Clinician should recognize the cardiovascular and metabolic impacts of MetS in men with LUTS, early risk factors optimization and use of appropriate medical therapy may possibly alter or slower the progression of LUTS/BPH, and potentially avoid unnecessary morbidities and mortalities from cardiovascular and metabolic diseases for those men.

    2015-03-01

    Benign paroxysmal positional vertigo is one of the most common types of vertigo caused by peripheral vestibular dysfunction. Although head trauma, migraine, long-term bed rest, Ménière disease, viral labyrinthitis, and upper respiratory tract infections are believed to be predisposing factors, most cases of benign paroxysmal positional vertigo are idiopathic. Ear surgery is another cause, but after non-otologic surgery, attacks of benign paroxysmal positional vertigo are rare. We describe three cases of benign paroxysmal positional vertigo attacks after non-otologic surgery (one patient after a nasal septoplasty and two patients after dental endodontic treatment) and discuss the pathophysiological mechanism of benign paroxysmal positional vertigo seen after non-otologic surgery, its diagnosis and treatment.

    2000-01-01

    Objective: To evaluate the value of CT for diagnosing benign diseases of breast. Methods: The breast CT scan and mammography were performed on 44 patients (78 focus). The accuracy of determining the position and nature of breast diseases was compared between the two mentioned diagnostic methods. All cases were confirmed as breast benign disease by pathology. Results: CT played a remarkable role in the diagnosis of breast fibroadenoma and cyst, and is superior to mammography in demonstrating deep breast lesion, multiple-focus and multiple-patterns benign diseases of breast. The accuracy of CT and mammography in determining the position and nature of benign diseases of breast were 85% and 54% (x 2 = 12.58, P 2 = 8.29, P < 0.01) respectively. Conclusion: CT has a higher accuracy than mammography in determining the position and nature of breast benign disease

  14. Cutaneous benign epithelioid peripheral nerve sheath tumour: A rare entity

    Directory of Open Access Journals (Sweden)

    Anuradha CK Rao

    2013-01-01

    Full Text Available Benign epithelioid peripheral nerve sheath tumor, a rare entity is an umbrella term describing benign, neural origin tumors with epithelioid morphology. Clinically indistinguishable from other benign cutaneous lesions, histopathology offers the only source of accurate diagnosis. Morphologic mimics include many benign and malignant soft tissue lesions. Besides a predominant epithelioid component, the lesion can also show a fair share of spindle cells. A circumscribed nodular tumour of low mitotic activity, it often exhibits areas resembling schwannoma or neurofibroma. An awareness of this entity and its varied morphological aspects helps to arrive at the correct diagnosis and hence avoid unnecessary extensive surgical procedures. This case presents features of this benign tumor which occurred in a 47 years old man.

    The association between deep vein thrombosis (DVT) and the hypercoagulable state is a well-established entity. However, the association between saphenous vein thrombophlebitis and coagulation abnormalities has not been investigated. Although thrombosis of varicose veins typically runs a benign course, phlebitis of the saphenous system may propagate to the deep system or saphenofemoral junction that requires more aggressive therapy. Given the potential similarity in clinical outcome between saphenous vein thrombophlebitis (SVT) and DVT, we have investigated the coagulation profile of patients presenting with isolated SVT. Seventeen consecutive patients who presented to our vascular laboratory with isolated SVT had a coagulation profile performed that included antithrombin III (AT III), protein C (PC), protein S (PS) antigen and activity levels, activated protein C (APC) resistance, factor V DNA mutation, and coagulation factors II and X. All patients had duplex scans performed on both the superficial and deep venous systems. Patients with SVT only were treated with nonsteroidal antiinflammatory drugs (NSAIDs) and warm soaks as outpatients, whereas those patients found to have DVT or a clot at the saphenofemoral junction were fully anticoagulated with heparin and coumadin therapy. All 17 patients had at least one repeat coagulation profile performed up to 5 months after their SVT occurrence to ensure that the results of hypercoagulability were not transient. Ten (59%) of the 17 patients with SVT had abnormal coagulation profiles on initial presentation. All 10 patients who were hypercoagulable had repeat tests and 6 (35%) remained abnormal. Four patients who had abnormal results converted to normal values. Seven patients with normal coagulation profiles on initial presentation had repeat tests and all remained normal. The incidence of the hypercoagulable state in patients with SVT is high. Thirty-five percent of patients with isolated SVT had consistently abnormal

  17. The Clinical and Neurophysiological Features of Epileptic Syndromes Associated with Benign Focal Epileptiform Discharges of Childhood

    Directory of Open Access Journals (Sweden)

    N. A. Ermolaenko

    2014-01-01

    Full Text Available Benign focal epileptiform discharge of childhood (BFEDC is an age-dependent pattern determined in electroencephalograms (EEGs, which is associated with idiopathic benign focal epilepsy (BFE. Studies of BFE revealed symptomatic phenocopies in patients with cerebral struc- tural abnormalities in such conditions as infantile cerebral palsy and malformations. Some arguments against the «benign» nature of BFEDC are presented, since BFEDC may impair various cognitive functions and behavior (e.g., cause epileptic encephalophathies. Objective. To determine the clinical and neurophysiological features of epileptic syndromes associated with prolonged epileptiform activity during sleep in children and adolescents, as well as approaches to rational therapy. Patients and Methods. A total of 1862 children aged 2–18 admitted to the specialized Department of Psychoneurology of the Voronezh Regional Children Clinical Hospital No 1 in 2004–2007, who had epileptic seizures and non-epileptic neurological disorders, were exam- ined. The children underwent assessment of the neurological status, neuropsychological assessment, and video-EEG monitoring. The spike- wave index (SWI was calculated and magnetic resonance imaging (MRI of the brain was performed to register the epileptiform activity during sleep. Results and Discussion. It was demonstrated that when ISW of BFEDC patterns is >30%, evolution into epileptic encephalopathy was observed in 66% of patients (including epilepsy with electrical status epilepticus in sleep in 49% of patients and cognitive epileptiform disinte- gration in 17% of patients. The results prove the justification of prescribing antiepileptic drugs to patients with SWI ≥30% even if they have no epileptic seizures. Duo-therapy with valproate and ethosuximide or levetiracetam is most the effective therapy. Further prospective studies for children with BFEDC will give new insight into this area.

    Full Text Available The articles presents a view of the pharmacological and nutritive therapy of the most frequent diseases of males, which are benign prostatic hyperplasia and chronic prostatitis. A modern man is in constant deficiency of various biologically active substances, with the lack of them in food and without generating of sufficient quantity of coenzymes and enzymes. In the author,s opinion, complex drugs that contain highquality biological extracts may provide the substances required for prevention and slowing down the progress of benign prostatic hyperplasia and chronic prostatitis to the male organism. Study of biological activity of food supplement Andro-PRO (Russia that contain the elements required for normalization of the functional state of the prostate was performed. Application of the drug favors positive dynamics of clinical symptoms of the studied nosological entities and has restorative effect on the function of the glandular tissue of the prostate. Analysis of modern references, primary results of clinical studies show the necessity of pharmacological and nutritive support of patients with asymptomatic progress of benign prostatic hyperplasia and chronic prostatitis with the drug. Application of drug studied is efficient and safe, which is confirmed with improvement of indicators and life quality assessment, positive clinical dynamics, and absence of side effects. 

  19. EFFECTIVENESS OF CANALITH RE POSITIONING PROCEDURE VERSUS BRANDT DAROFF EXERCISES IN BENIGN PAROXYSMAL POSITIONAL VERTIGO SUBJECTS

    Suneel Kumar

    2016-08-01

    Full Text Available Background: Vertigo is perception of motion, when no movement is present or abnormal perception of motion in response to movement. Vertigo is usually due to a disturbance in the vestibular System. Physical therapy plays an important role in reducing vertigo and nystagmus in benign paroxysmal positional vertigo subjects. Benign paroxysmal positional vertigo(BPPV comes under the peripheral Vertigo which is the most common disease causing vertigo. Cawthrone and cooksy were the first clinicians to advocate exercises for persons suffering from vertigo. Canalith repositioning procedure was effective in treating BPPV. Brandt Daroff exercises were designed to habituate the central nervous system to provoking position and they dislodge and move the debris out of canal which is effective in treating BPPV. Hence this study compares the effectiveness of these two techniques in treating BPPV. Methods: Total number of 30 subjects was taken and they were divided into two groups by simple random sampling method with Pre test and post test experimental design . Group A subjects were treated with Canalith repositioning procedure and Group B subjects were treated with Brandt Daroff exercises. Outcome measure is dizziness handicap inventory (DHI Results: P-value is less than 0.05 which shows that there is significant difference between Canalith repositioning procedure and Brandt Daroff exercises. Conclusion: Canalith repositioning procedure is most effective and less time consuming procedure in treating the Benign Paroxysmal positional vertigo subjects and found to have less reoccurrence.

    Full Text Available Fouad Aoun1, Quentin Marcelis,1,2 Thierry Roumeguère,2 1Department of Urology, Jules Bordet Institute, 2Department of Urology, Erasme Hospital, University Clinics of Brussels, Université Libre de Bruxelles, Brussels, Belgium Abstract: Benign prostatic hyperplasia (BPH represents a spectrum of related lower urinary tract symptoms (LUTS. The cost of currently recommended medications and the discontinuation rate due to side effects are significant drawbacks limiting their long-term use in clinical practice. Interventional procedures, considered as the definitive treatment for BPH, carry a significant risk of treatment-related complications in frail patients. These issues have contributed to the emergence of new approaches as alternative options to standard therapies. This paper reviews the recent literature regarding the experimental treatments under investigation and presents the currently available experimental devices and techniques used under local anesthesia for the treatment of LUTS/BPH in the vast majority of cases. Devices for delivery of thermal treatment (microwaves, radiofrequency, high-intensity focused ultrasound, and the Rezum system, mechanical devices (prostatic stent and urethral lift, fractionation of prostatic tissue (histotripsy and aquablation, prostate artery embolization, and intraprostatic drugs are discussed. Evidence for the safety, tolerability, and efficacy of these “minimally invasive procedures” is analyzed.

    In this study, we sought to define the incidence of benign renal tumors in our institute and to clarify the clinical factors associated with benign renal tumors, in order to assist in forming preoperative differential diagnoses. From October 2002 to July 2007, we performed 157 nephrectomies in patients preoperatively diagnosed with renal cell carcinoma. We chose 81 tumors, all of which were less than 5 cm, for further study. We reviewed double-phase helical CT imaging retrospectively, specifically focusing on attenuation patterns and homogeneity. We also compared clinical factors, including age, sex and tumor size, between the benign and malignant renal tumors. The patient's median age was 67 years (mean age, 63 years), and the median tumor diameter was 3.0 cm (mean, 3.2 cm). Benign renal tumors were found in 10 (12%) of the 81 tumors; these included seven cases of oncocytoma and three cases of angiomyolipoma with minimal fat. Several factors were significant clinical determinants of differentiation between benign and malignant renal tumors: homogeneity in CT, female gender, and small tumor size all predominated in cases of benign tumors. Attenuation pattern in CT, however, was not a significant factor (p=0.344). When a patient, especially a female, presents with a small and homogeneous renal tumor, careful consideration should be given to the possibility of a benign process, which needs further consideration before performing excessive surgery.

    1988-01-01

    The authors report their experience of benign urethral stricture dilatation by balloon catheter in 11 male patients. Ten posterior and 2 anterior urethral strictures were treated; in 1 patients several narrowings coexisted at various levels. Etiology was inflammatory in 4 cases, iatrogen in 3, post-traumatic in 2, and equivocal in 2. The patients were studied both before and soon after dilatation by means of retrograde and voiding cystourethrogram and uroflowgraphy; the follow-up (2-14 months) was performed by urodynamic alone. In all cases, dilatation was followed by the restoration of urethral gauge, together with prompt functional improvement of urodynamic parameters. The latter result subsisted in time in 9 patients. In 2 cases recurrences were observed demonstrated at once by clinics and urodynamics. Both lesions were successfully re-treated. Neither early not late complication occurred. In spite of the limited material, the valuable results obtained, together with the absence of complications, the peculiar morphology of recurrences, and the chance of repeating it make the procedure advisable as a valid alternative to conventional techniques for these pathologies

    1992-05-01

    The Authors present the first case described among us of benign pleural effusion of an asbestotic origin. They stress the importance of thoracoscopy (pleuroscopy) in the diagnosis of this situation. Attention is drawn to the fact that asbestotic lesions and asbestotic bodies have been found in the lung and, in particular, in the parietal pleura as well. They emphasize the fact that exposure to asbestos was not realized by the patient, which made the clarification of the situation more difficult. It was a CT scan that showed the signs suggestive of exposure to asbestos which raised the diagnostic suspicion. They conclude that every patient with a pleural effusion must be thoroughly questioned about exposure to asbestos. Even if the exposure is accepted, they consider that one should proceed to a pleuro-pulmonar biopsy by thoracoscopy. This biopsy allows demonstration of the characteristic histopathological lesions and rule out other etiologies, namely malignancy and tuberculosis. They suggest that these patients must be highly motivated to stop any smoking and kept under periodic surveillance.

    Benign subcutaneous lesions are a common reason that patients visit family physicians. Lipomas are the most common of these lesions; they most often occur on the trunk and proximal extremities. Recent data show that as many as half of the fat cells in lipomas are atypical. Ultrasound is used increasingly to confirm lipoma diagnosis, but deep lesions should be evaluated with magnetic resonance imaging study or computed tomography scan to exclude involvement of underlying structures and/or liposarcoma. Small lesions can sometimes be managed with serial injections of midpotency steroids. Larger lesions (larger than 5 cm), those compressing other structures, or those suspicious for malignancy should be excised using standard surgical excision or, when possible, the newer minimal-scar segmental extraction technique. Ganglion cysts are another common lesion, the presence of which often is confirmed with ultrasound if the diagnosis is not clinically apparent. Management includes splinting, aspiration, and/or injection of steroids, with or without hyaluronidase. Epidermal inclusion cysts, also called sebaceous cysts, typically are asymptomatic unless they become infected. Ultrasound can aid in diagnosis. The only definitive management is surgical excision with complete removal of the cyst wall or capsule, using minimal-scar segmental extraction or conventional surgical removal.

    In our clinical experience, some of the patients affected by benign paroxysmal positional vertigo (BPPV) reported the onset of tinnitus shortly before or in association with the positional vertigo. The aim of this study was to describe the prevalence and the clinical patterns of tinnitus episodes which occurred in association with BPPV and to suggest possible interpretative hypotheses. 171 normal hearing patients affected by BPPV (50 males and 122 females; age range: 25-77 years; mean age 60.3 years ± 14.9) underwent pure tone audiometry, immittance test and a clinical vestibular evaluation before and after repositioning manoeuvers. Those suffering from tinnitus were also assessed using visual analogue scales and tinnitus handicap inventory. 19.3% of the patients reported the appearance of tinnitus concurrently with the onset of the positional vertigo. It was mostly unilateral, localized on the same ear as the BPPV, slight in intensity and intermittent. Tinnitus disappeared or decreased in all patients except two, either spontaneously, before performing the therapeutic manoeuvers, or shortly after. A possible vestibular origin of tinnitus determined by the detachment of macular debris into the ductus reuniens and cochlear duct is discussed.

    The possible association between cigarette smoking and the risk of benign breast disease (BBD) was assessed in a case-control study conducted in Gdansk, Poland, between 1990 and 1994. The study compared 160 women with newly diagnosed BBD admitted to the Gdansk Cancer Outpatients Clinic and 160 controls, women from outpatients clinics at the Medical University of Gdansk. There was no convincing evidence of an association, either positive or negative, between various indicators of smoking habit (smoking status, number of cigarettes smoked per day, duration of smoking) and the risk of BBD. Slightly lower relative risk (RRs) of BBD in ex-smokers of 10 or more cigarettes per day (RR = 0.9; 95% confidence interval, CI: 0.4-2.2), and with duration of smoking >= (RR = 0.1-3.4), were also observed in current smokers (RR = 0.8; 95% CI: 0.4-1.5), and (RR = 0.8; 95% CI: 0.1-3.4), but these findings were not statistically significant.

    Full Text Available Elastofibroma dorsi is an uncommon benign soft tissue pseudotumour usually located at the lower pole of the scapula, deep to serratus anterior, and often attached to the periosteum of the ribs, presenting with long history of swelling and occasionally pain and discomfort. This lesion is usually seen in patients over the age of 50 years and is not uncommonly mistaken as a malignant tumour because of its size and location deep to the periscapular muscles. Review of the orthopaedic oncology database of 17 500 patients revealed that there were 15 patients with elastofibroma dorsi. There were 12 males and 3 females, mean age at diagnosis of 68.4 years range 51–79 years. The diagnosis was confirmed by MRI in 3 patients, excision biopsy in 3 patients, trucut biopsy in 8 patients and open biopsy in 1 patient. Eight patients had excision of the lesion which was symptomatic. There have been no recurrences. We highlight the clinical and radiological presentation of elastofibroma dorsi to increase awareness of its existence and management.

    Objective This study was designed to examine the age and gender distribution and the effect of menopause in a large cohort of participants diagnosed with benign paroxysmal positional vertigo (BPPV). Methods We analyzed 1,377 BPPV patients and surveyed 935 women from this group, all diagnosed at Boys Town National Research Hospital (BTNRH) over the last decade. Results A detailed age- and gender- distribution analysis of BPPV onset showed that aging had a profound impact on BPPV occurrence in both genders, and that peri-menopausal women were especially susceptible to BPPV (3.2:1 female to male). The latter is a novel finding and was confirmed by a direct survey of female BPPV patients (168 participated). In addition, there was a pronounced female preponderance (6.8:1) for BPPV in the teenage group despite the low prevalence in this age group. Conclusions The data suggest that hormonal fluctuations (especially during menopause) may increase the tendency to develop BPPV. PMID:24496089

    Full Text Available Benign paroxysmal positional vertigo (BPPV, the most common cause of dizziness, occurs in all age groups. It presents with vertigo on head movement, but in older patients presentation may be typical and thus accounting for a low recognition rate in the primary care setting. It may be recurrent in up to 50% of cases. BPPV is associated with displacement of fragments of utricular otoconia into the semicircular canals, most commonly the posterior semicircular canal. Otoconia are composed of otoconin and otolin forming the organic matrix on which calcium carbonate mineralizes. Otoconia may fragment with trauma, age, or changes in the physiology of endolymph (e.g., pH and calcium concentration. Presentation varied because otoconia fragments can be displaced into any of the semicircular canals on either (or both side and may be free floating (canalolithiasis or attached to the cupula (cupulolithiasis. Most cases of BPPV are idiopathic, but head trauma, otologic disorders, and systemic disease appear to be contributory in a subset. Positional maneuvers are used to diagnose and treat the majority of cases. In rare intractable cases surgical management may be considered. A strong association with osteoporosis suggests that idiopathic BPPV may have diagnostic and management implications beyond that of a purely otologic condition.

    Benign tremulous parkinsonism (BTP) is characterized by a prominent tremor that occurs both at rest and with action in conjunction with other mild features of parkinsonism. The progression of symptoms is typically slow and there is often a positive family history. Although BTP is included within the phenotypic spectrum of Parkinsonism its exact relationship with idiopathic Parkinson's disease remains unclear. Treatment of BTP is challenging especially considering the poor response to levodopa, therefore surgical therapies such as deep brain stimulation surgery are sought for treatment of these tremors. In this review, we will summarize the clinical features, diagnosis, neuropathology and treatment for BTP.

    During recent years, pharmacological treatment of symptomatic benign prostatic hyperplasia (BPH) has become the primary treatment choice for an increasing number of patients. The 2 principal drug classes employed are alpha 1-blockers and 5 alpha-reductase inhibitors. Current information from...... of patients who will respond well to alpha 1-blockers have yet to be identified, and data concerning the long term effects of these drugs are not yet available. 5 alpha-Reductase inhibitors have a slow onset of effect, but treatment leads to improvement in symptoms, reduction of the size of the prostate gland...... or unwilling to undergo surgical resection of the prostate will benefit from such therapy....

  12. Benign osseous metaplasia of the breast: Case report

    Directory of Open Access Journals (Sweden)

    Hassan Alyami

    Full Text Available Introduction: Benign Osseous metaplasia of the breast is rare, with only a few cases reported in the literature. Here we present a case of benign osseous metaplasia of the breast presenting as a breast lump. Case presentation: 38-year-old previously well woman presented with a one-year history of bilateral breast pain and a left-sided breast lump. Ultrasound and mammography suggested calcified fibroadenoma. An ultrasound-guided true cut biopsy revealed fibrous tissue containing foci of adenosis in the presence of a myoepithelial cell layer. Excision biopsy was performed, and histopathological examination showed bone matrix deposition occupying most of the nodule with peripheral hyalinized tissue but no evidence of malignancy. A diagnosis of benign osseous metaplasia of the breast was made, and the patient recovered well without recurrence after lump excision. Discussion: Only a few cases of osseous metaplasia are reported in the literature. Most reported cases are malignant, such as in fibrosarcoma, malignant mesenchymoma, osteoid sarcoma, osteogenic sarcoma, and osteochondrosarcoma.Very few cases of osseous sarcoma are reported in benign lesions such as fibroadenoma, pleomorphic adenoma, benign mesenchymoma, phyllodes tumor, and amyloid tumor of the breast. Joshi et al. first reported a case of benign osseous metaplasia of the breast presenting as breast lump in an HIV-positive patient [18]. We, therefore, consider this case to be the second case report of benign osseous metaplasia of the breast presenting as a breast lump, but the patient had no chronic illness. Conclusion: A breast lump can be the first presentation of benign osseous metaplasia. Keywords: Benign osseous metaplasia, Breast lump, Case report

    To study employment in benign multiple sclerosis (MS), the frequency of employment was analysed and the effect of early clinical and demographic factors on time to disability pension was evaluated in a population based MS cohort. The frequency of depression, cognitive function, fatigue and pain between benign and non-benign MS patients was compared, and their impact on employment in benign MS was studied. All 188 patients alive, including 60 benign patients with onset of MS during 1976-1986 in Hordaland County, Western Norway, were interviewed and clinically examined in 2003. The Expanded Disability Status Scale (EDSS), depression (Beck Depression Inventory), cognitive function, fatigue, pain, year of disability pension, employment and type of occupation were registered. Benign MS was defined as an EDSS score ≤3.0 at least 10 years after disease onset. After a mean disease duration of 22.2 years, 32.4% of the cohort were still employed. A relapsing-remitting course, higher educational level and light physical work were significantly associated with longer time to disability pension in the general MS population. Thirty-nine (65.0%) benign MS patients were employed, independent of light or heavy physical work. Mild depressive symptoms were markedly associated with not being employed in benign MS (OR=7.3). A relapsing-remitting course, higher educational level and light physical work significantly predicted longer time to disability pension in the total MS population. Among the benign MS patients, depressive symptoms, although mild, were strongly associated with not being employed.

    Full Text Available BACKGROUND AND OBJECTIVES The breast is the essential symbol of womanhood to society and to the woman herself. Subjected every month to the onslaught of ovarian, adrenal, pituitary and thyroid hormones in tandem with the uterus, the very histological architecture of the breast changes sequentially. With the recent importance given to early diagnosis of cancer of the breast and its early detection by both the patient and her physician, more benign conditions are likely to be detected than earlier. The objective of our review is to find out the incidence of benign breast lump above 40 years of age in females attending our hospital. METHODS AND MATERIALS 130 patients presenting to the outpatient department of KAPV Medical College with breast lump were included in this comprehensive study. A detailed history regarding the duration and nature of the complaints, family history pertaining to breast or ovarian cancers, risk factors such as oral contraceptive use, parity, lactation, etc. was elicited. A thorough clinical examination was performed. RESULTS Of 24 cases of fibroadenoma, all were operated upon by excision. Of 38 patients with fibroadenosis, 30 patients managed conservatively and surgery for 8 patients where the diagnosis was doubtful. Abscesses were incised and drained under antibiotic cover for 3 patients. 8 cases of breast cyst were managed by aspiration. TB mastitis was confirmed by excisional biopsy and followed up by antituberculous therapy with regular follow up after 6 months. Healed lesions were found to be associated with improved general condition of the patients. Lipoma and sebaceous cyst were managed by excision biopsy. CONCLUSION Benign breast diseases were found to be common in woman above 40 years old in contrast to normal teaching, which says they are common in younger age groups. Fibroadenosis was the commonest benign disease closely followed by fibroadenoma. Fibroadenosis was mostly managed conservatively. Excision biopsy

    Full Text Available Background/Aim. Gastric ulcer may be benign or malignant. In terms of therapy and patient’s prognosis early detection of malignancy is very important. The aim of this study was to assess the usefulness of endoscopic ultrasound (EUS in differentiation between benign and malignant gastric ulcer. Methods. A prospective study included 20 consecutive adult patients with malignant gastric ulceration and 20 consecutive adult patients with benign gastric ulceration. All the patients underwent EUS. A total of 6 parameters were analyzed: ulcer width, ulcer depth, the thickness of the gastric wall along the edge of ulceration (T0, the thickness of the gastric wall 2 cm from the edge of ulceration (T2, loss of layering structure of the gastric wall, and the presence of regional lymph nodes. EUS criteria for malignancy and a point-score of malignancy were defined. The critical value of total point-score was also calculated showing the best reliability parameters. Results. There are 4 criteria for malignancy of gastric ulceration: T0 > 10 mm, T2 > 5 mm, EUS visualization of at least one lymph node, loss of layering structure of the gastric wall. Furthermore, T2 > 5 mm was the only EUS independent predictor of ulcer malignancy. The total point score of ≥ 4 was the cut-off pointscore value which gave the best reliability parameters in the assessment of malignant ulcers: sensitivity of 70%, specificity of 95%, positive predictive value of 93.3%, negative predictive value of 76% and accuracy of 82.5%. Conclusion. According to the results obtained in this study, we can conclude that EUS is usefull in differentiation between benign and malignant gastric ulcer.

    2004-01-01

    Focal lesions of the liver often have various imaging characteristics which may be interpreted as either benign or malignant. Understanding the underlying pathophysiology of these liver lesions may lead to characteristic imaging manifestations, which direct the radiologist to the diagnosis. Benign lesions include congenital hepatic cyst, autosomal dominant polycystic disease, hemangioma, focal nodular hyperplasia (FNH), hepatic adenoma, inflammatory pseudotumor, peliosis hepatis, focal fatty infiltration, hamartoma, and infectious processes such as hepatic abscess, echinococcal cyst, and candidiasis. Characteristic imaging features, clinical symptoms, and treatment/prognosis will be discussed. Emphasis will be placed on key reliable features of each disease to develop a method of discriminating these lesions from other benign and malignant disorders.

    Surgery has been the classic treatment of choice for benign cystic diseases, including lymphatic malformation, ranula, branchial cleft cyst, thyroglossal duct cyst, thyroid cyst, parathyroid cyst, and lymphocele. However, surgery is associated with a tendency toward recurrence and may be accompanied by various complications, such as nerve injuries, vascular injuries, and scar formation. Therefore, sclerotherapy using various agents has been applied successfully to treatment of benign cystic diseases in the neck. This editorial reviews the use of various sclerotic agents and application of sclerotherapy to benign cystic diseases in the neck.

    Transurethral resection of the prostate (TURP) has been the gold-standard treatment for alleviating urinary symptoms and improving urinary flow in men with symptomatic benign prostatic hyperplasia (BPH). However, the morbidity of TURP approaches 20%, and less invasive techniques have been developed for treating BPH. Preliminary data suggest that microwave thermotherapy, which delivers microwave energy to produce coagulation necrosis in prostatic tissue, is a safe, effective treatment for BPH. To assess the therapeutic efficacy and safety of microwave thermotherapy techniques for treating men with symptomatic benign prostatic obstruction. Randomized controlled trials were identified from The Cochrane Library, MEDLINE, EMBASE, bibliographies of retrieved articles, reviews, technical reports, and by contacting relevant expert trialists and microwave manufacturers. All randomized controlled trials evaluating transurethral microwave thermotherapy (TUMT) for men with symptomatic BPH were eligible for this review. Comparison groups could include transurethral resection of the prostate, minimally invasive prostatectomy techniques, sham thermotherapy procedures, and medications. Outcome measures included urinary symptoms, urinary function, prostate volume, mortality, morbidity, and retreatment. Two review authors independently identified potentially relevant abstracts and then assessed the full papers for inclusion. Two review authors independently abstracted study design, baseline characteristics, and outcomes data and assessed methodological quality using a standard form. We attempted to obtain missing data from authors or sponsors, or both. In this update, we identified no new randomized comparisons of TUMT that provided evaluable effectiveness data. Fifteen studies involving 1585 patients met the inclusion criteria, including six comparisons of microwave thermotherapy with TURP, eight comparisons with sham thermotherapy procedures, and one comparison with an alpha

    A fall in the postpneumonectomy fluid level is considered a sign of bronchopleural fistula (BPF) requiring surgical intervention. We have discovered however that in rare asymptomatic patients, this event may not require aggressive surgical treatment. After seeing a case of benign emptying of the postpneumonectomy space (BEPS), we surveyed 28 surgeons to determine its incidence and characteristics. Forty-four cases of BEPS were reported by 23 survey respondents. Among 7 fully documented cases from 4 institutions, we defined the following criteria: the patient must be asymptomatic (no fever, white cell count elevation, or fluid expectoration), negative culture results if fluid sampled (patient not receiving antibiotics), no BPF at bronchoscopy or ventilation scintigraphy scan (or both), and recovery without drainage, or retrospective assessment that the intervention was unnecessary. BEPS occurred between 5 days and 152 days after pneumonectomy (6 cases right pneumonectomy and 1 case left pneumonectomy). Four patients underwent no treatment, 1 patient underwent thoracoscopic exploration (sterile) and closure after antibiotic irrigation, 1 patient underwent thoracoscopic exploration alone, and 1 patient underwent open window thoracostomy (sterile) with eventual closure. In all 7 patients (except the patient who underwent the open window procedure) the space refilled within 8 weeks; no patient experienced a subsequent empyema/BPF. Four patients who met the initial criteria for BEPS went on to experience empyema. The incidence of BEPS appears related to pneumonectomy volume, particularly extrapleural pneumonectomy. Using surgeon volume assumptions, the incidence of BEPS is 0.65%. To our knowledge, BEPS is a previously unreported occurrence. We hypothesize that it results from postoperative intrapleural pressure shifts, with or without a microscopic BPF, that drive fluid out of the pleural space while failing to cause contamination. Awareness of BEPS' existence may allow

    Benign prostatic hyperplasia (BPH) is a common condition in adult men and its incidence increases progressively with aging. It has an important impact on the individual's physical and mental health and its natural progression can lead to serious pathological situations. Although the initial treatment is pharmacological, except in specific situations, the tendency of disease progression causes a considerable portion of the patients to require surgical treatment. In this case, there are several options available today in the therapeutic armamentarium. Among the options, established techniques, such as open surgery and endoscopic resection using monopolar energy, still prevail in the choice of surgeons because they are more accessible, both from a socioeconomic standpoint in the vast majority of medical services and in terms of training of medical teams. On the other hand, new techniques and technologies arise sequentially in order to minimize aggression, surgical time, recovery and complications, optimizing results related to the efficacy/safety dyad. Each of these techniques has its own peculiarities regarding availability due to cost, learning curve and scientific consolidation in order to achieve recognition as a cutting-edge method in the medical field. The use of bipolar energy in endoscopic resection of the prostate, laser vaporization and enucleation techniques, and videolaparoscopy are examples of new options that have successfully traced this path. Robot-assisted surgery has gained a lot of space in the last decade, but it still needs to dodge the trade barrier. Other techniques and technologies will need to pass the test of time to be able to conquer their space in this growing market.

    Full Text Available Purpose: To investigate the chromosomal changes in patients with benign prostatic hyperplasia (BPH. Materials and Methods: A total of 54 patients diagnosed with clinical BPH underwent transurethral prostate resection to address their primary urological problem. All patients were evaluated by use of a comprehensive medical history and rectal digital examination. The preoperative evaluation also included serum prostate-specific antigen (PSA measurement and ultrasonographic measurement of prostate volume. Prostate cancer was detected in one patient, who was then excluded from the study. We performed conventional cytogenetic analyses of short-term cultures of 53 peripheral blood samples obtained from the BPH patients. Results: The mean (±standard deviation age of the 53 patients was 67.8±9.4 years. The mean PSA value of the patients was 5.8±7.0 ng/mL. The mean prostate volume was 53.6±22.9 mL. Chromosomal abnormalities were noted in 5 of the 53 cases (9.4%. Loss of the Y chromosome was the most frequent chromosomal abnormality and was observed in three patients (5.7%. There was no statistically significant relationship among age, PSA, prostate volume, and chromosomal changes. Conclusions: Loss of the Y chromosome was the main chromosomal abnormality found in our study. However, this coexistence did not reach a significant level. Our study concluded that loss of the Y chromosome cannot be considered relevant for the diagnosis of BPH as it is for prostate cancer. Because BPH usually occurs in aging men, loss of the Y chromosome in BPH patients may instead be related to the aging process.

  2. Italian survey on benign paroxysmal positional vertigo.

    2017-08-01

    Benign paroxysmal positional vertigo (BPPV) is the most common type of peripheral vertigo. BPPV often relapses after the first episode, with a recurrence rate between 15% and 50%. To date both the aetiopathogenetic processes that lead to otoconia detachment and the factors that make BPPV a relapsing disease are still unclear, but recent epidemiological studies have shown a possible association with cardiovascular risk factors. The aim of the present study (Sesto Senso Survey) was to evaluate in the Italian population through an observational survey, the main demographic and clinical characteristics of patients with BPPV (first episode or recurrent) with particular focus on the potential cardiovascular risk factors. The survey was conducted in 158 vestibology centres across Italy on 2,682 patients (mean age 59.3 ± 15.0 years; 39.1% males and 60.9% females) suffering from BPPV, from January 2013 to December 2014. The results showed a high prevalence of cardiovascular risk factors such as high blood pressure (55.8%), hypercholesterolaemia (38.6%) and diabetes (17.7%), as well as a family history of cardiovascular disease (49.4%). A high percentage of patients also had hearing loss (42.9%), tinnitus (41.2%), or both (26.8%). The presence of hypertension, dyslipidaemia and pre-existing cardiovascular comorbidities were significantly related to recurrent BPPV episodes (OR range between 1.84 and 2.31). In addition, the association with diabetes and thyroid/autoimmune disease (OR range between 1.73 and 1.89) was relevant. The survey results confirm the significant association between cardiovascular comorbidities and recurrent BPPV and identify them as a potential important risk factor for recurrence of BPPV in the Italian population, paving the way for the evaluation of new therapeutic strategies in the treatment of this disease. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.

    2016-01-01

    Benign prostatic hyperplasia (BPH) is characterized by increased tissue mass in the transition zone of the prostate, which leads to obstruction of urine outflow and significant morbidity in the majority of older men. Plasma markers of oxidative stress are increased in men with BPH but it is unclear whether oxidative stress and/or oxidative DNA damage are causal in the pathogenesis of BPH. Levels of 8-OH deoxyguanosine (8-OH dG), a marker of oxidative stress, were measured in prostate tissues from normal transition zone and BPH by ELISA. 8-OH dG was also detected in tissues by immunohistochemistry and staining quantitated by image analysis. Nox4 promotes the formation of reactive oxygen species. We therefore created and characterized transgenic mice with prostate specific expression of Nox4 under the control of the prostate specific ARR2PB promoter. Human BPH tissues contained significantly higher levels of 8-OH dG than control transition zone tissues and the levels of 8-OH dG were correlated with prostate weight. Cells with 8-OH dG staining were predominantly in the epithelium and were present in a patchy distribution. The total fraction of epithelial staining with 8-OH dG was significantly increased in BPH tissues by image analysis. The ARR2PB-Nox4 mice had increased oxidative DNA damage in the prostate, increased prostate weight, increased epithelial proliferation, and histological changes including epithelial proliferation, stromal thickening, and fibrosis when compared to wild type controls. Oxidative stress and oxidative DNA damage are important in the pathogenesis of BPH. © 2015 Wiley Periodicals, Inc.

  4. Dynamic computed tomography scanning of benign bone lesions: Preliminary results

    Levine, E.; Neff, J.R.

    1983-01-01

    The majority of benign bone lesions can be evaluated adequately using conventional radiologic techniques. However, it is not always possible to differentiate reliably between different types of benign bone lesions on the basis of plain film appearances alone. Dynamic computed tomography (CT) scanning provides a means for further characterizing such lesions by assessing their degree of vascularity. Thus, it may help in distinguishing an osteoid osteoma, which has a hypervascular nidus, from a Brodie's abscess, which is avascular. Dynamic CT scanning may also help in the differentiation between a fluid-containing simple bone cyst, which is avascular, and other solid or semi-solid benign bone lesions which slow varying degrees of vascularity. However, because of the additional irradiation involved, dynamic CT scanning should be reserved for evaluation of selected patients with benign bone lesions in whom the plain film findings are not definitive and in whom the CT findings may have a significant influence on management.

    In summary, the lecture presents today's state of nuclear medical diganostics in benign bone disease, the radiopharmaceuticals, and the methods used. Besides the [sup 99]m-Tc-labeled diphosphonates a couple of additional radioactive labeled substances play an important part in bone scintigraphic imaging especially in scanning inflammatory bone disease and the bone marrow. There are several substances available to label leucocytes and human immunoglobulins. Concerning the methods the performance of the 3-phase bone scanning and the application of SPECT becomes increasingly important. In detail discussed are among other methods the inflammation-scanning in osteomyelitis, the scintigraphic imaging in benign bone tumors and tumor like lesions, in circulation disorders of the bone with necroses and hyperperfusion (reflex sympathetic dystrophy, transient hip osteoporosis), and in bone lesions following trauma or stress, for example also in battered child syndrome. The indication to the different imaging procedures as X-ray, computed tomography, nuclear magnetic resonance, and scintigraphic imaging are discussed, whereby the scintiscanning urges its place, mainly due to good specifity, in documenting the different functional states of the bone such as inflammation, perfusion, necrosis, tumor and/or bone marrow infiltration.

    There is a significant lack of uniform agreement regarding nomenclature for benign vocal fold lesions (BVFLs). This confusion results in difficulty for clinicians communicating with their patients and with each other. In addition, BVFL research and comparison of treatment methods are hampered by the lack of a detailed and uniform BVFL nomenclature. Clinical consensus conferences were held to develop an initial BVFL nomenclature paradigm. Perceptual video analysis was performed to validate the stroboscopy component of the paradigm. The culmination of the consensus conferences and the video-perceptual analysis was used to evaluate the BVFL nomenclature paradigm using a retrospective review of patients with BVFL. An initial BVFL nomenclature paradigm was proposed utilizing detailed definitions relating to vocal fold lesion morphology, stroboscopy, response to voice therapy and intraoperative findings. Video-perceptual analysis of stroboscopy demonstrated that the proposed binary stroboscopy system used in the BVFL nomenclature paradigm was valid and widely applicable. Retrospective review of 45 patients with BVFL followed to the conclusion of treatment demonstrated that slight modifications of the initial BVFL nomenclature paradigm were required. With the modified BVFL nomenclature paradigm, 96% of the patients fit into the predicted pattern and definitions of the BVFL nomenclature system. This study has validated a multidimensional BVFL nomenclature paradigm. This vocal fold nomenclature paradigm includes nine distinct vocal fold lesions: vocal fold nodules, vocal fold polyp, pseudocyst, vocal fold cyst (subepithelial or ligament), nonspecific vocal fold lesion, vocal fold fibrous mass (subepithelial or ligament), and reactive lesion.

    The Eustachian tube (ET) is responsible for the ventilation, protection, and cleaning of the middle ear. ET dysfunction plays an important role in the pathogenesis of otitis media cases, and thus the treatment and prognosis of these cases is extremely dependent on adequate ET function, which can ultimately affect the success rate of middle ear reconstruction practices. Data research on the ET’s ventilation function is needed to ensure the success of therapy and surgery treatments in the case of Chronic Suppurative Otitis Media (CSOM) patients. This study aims to investigate ET ventilation functioning in benign type CSOM and non-otitis media subjects and to develop another modality to measure ET ventilation functioning in patients with intact and perforated tympanic membranes. A comparative cross-sectional study of 36 benign type CSOM patients and 80 non-otitis media subjects will be conducted using sonotubometry and the rated parameter measurements of ET opening frequency, amplitude and ET opening duration. Malfunctioning ventilation of the ET is more common among benign type CSOM subjects (47%) than among non-otitis media subjects (18.75%). There is a significant difference (p = 0.002) between the ET ventilation functioning of benign type CSOM subjects and non-otitis media subjects—benign type CSOM subjects have rates of malfunctioning ET ventilation that are 3.88 times higher than those of non-otitis media subjects. Patients with benign type CSOM are more likely to experience malfunctioning ET ventilation than are non-otitis media subjects.

    Benign lesions of the nasal cavity represent a diverse group of pathologies. Furthermore, each of these disorders may present differently in any given patient as pain and discomfort, epistaxis, headaches, vision changes, or nasal obstruction. Although these nasal masses are benign, many of them have a significant capacity for local tissue destruction and symptomatology secondary to this destruction. Advances in office-based endoscopic nasendoscopy have equipped the otolaryngologist with a safe, inexpensive, and rapid means of directly visualizing lesions within the nasal cavity and the initiation of appropriate treatment. The purpose of this study is to review the diagnosis, management, and controversies of many of the most common benign lesions of the nasal cavity encountered by the primary care physician or otolaryngologist. This includes discussion of inverted papilloma (IP), juvenile angiofibroma, squamous papilloma, pyogenic granuloma, hereditary hemorrhagic telangiectasia, schwannoma, benign fibro-osseous lesions, and other benign lesions of the nasal cavity, with particular emphasis on IP and juvenile angiofibroma. A diverse array of benign lesions occur within the nasal cavity and paranasal cavities. Despite their inability to metastasize, many of these lesions have significant capability for local tissue destruction and recurrence.

    External fractionated radiotherapy of cancer increases the risk of cardio- and cerebrovascular events, but less attention has been paid to the potential side effects on the arteries following internal radiotherapy with radioactive iodine (RAI), i.e. 131-iodine. About 279 per million citizens in the western countries are treated each year with RAI for benign thyroid disorders (about 140,000 a year in the EU), stressing that it is of clinical importance to be aware of even rare radiation-induced side effects. In order to induce or accelerate atherosclerosis, the dose to the carotid arteries has to exceed 2 Gy which is the known lower limit of ionizing radiation to affect the endothelial cells and thereby to induce atherosclerosis. To estimate the radiation dose to the carotid arteries following RAI therapy of benign thyroid disorders. Assuming that the lobes of the thyroid gland are ellipsoid, that the carotid artery runs through a part of the lobes, that there is a homogeneous distribution of RAI in the lobes, and that the 24 h RAI uptake in the thyroid is 35% of the 131 I orally administrated, we used integrated modules for bioassay analysis and Monte Carlo simulations to calculate the dose in Gy/GBq of administrated RAI. The average radiation dose along the arteries is 4-55 Gy/GBq of the 131 I orally administrated with a maximum dose of approximately 25-85 Gy/GBq. The maximum absorbed dose rate to the artery is 4.2 Gy/day per GBq 131 I orally administrated. The calculated radiation dose to the carotid arteries after RAI therapy of benign thyroid disorder clearly exceeds the 2 Gy known to affect the endothelial cells and properly induce atherosclerosis. This simulation indicates a relation between the deposited dose in the arteries following RAI treatment and an increased risk of atherosclerosis and subsequent cerebrovascular events such as stroke.

    There have been several publications on population or community prevalence of benign prostatic hyperplasia and prostate cancer from various countries and races but few reports are from Africa on Africans. A review on the prevalence of benign prostatic hyperplasia and prostate cancer in Africans and other races. The current literature on prevalence of benign prostatic hyperplasia (BPH), prostate cancer (PC), and benign prostatic hyperplasia co-existing with prostate cancer in Africans and other races is reviewed. Benign prostatic hyperplasia (BPH) prevalence in Ghana is responsible for 60% acute retention of urine and 28.6% of haematuria. Worldwide prevalence of BPH varies from 20 - 62% in men over 50 years and this includes USA, UK, Japan and Ghana. Reports from South Africa indicate prevalence of over 50% in adult males of 60 years. BPH co-existing with PC - Reports from USA, UK and Japan and Ghana reveal moderate association of BPH and PC. The co-existence of PC in patients being treated for BPH is 3 - 20% Prostate Cancer prevalence - There is high prevalence in USA, Scandinavian Countries, African Americans (AA) and Caribbean blacks. Ghana, Trinidad & Tobago have reported high prevalence of 6 -10% in men aged 50 years and above but others reported low prevalence in Africans from Africa. The low reporting from Africa of 10 - 40:100,000 is attributable to under reporting, absence of PSA screening/testing, lack of reliable cancer registries and poor medical facilities. Economic Costs of BPH and PC: BPH in the USA national direct costs are estimated at U$4Billion and individual costs of US$1536 annually. In Ghana, individual costs for BPH medications range from US$300 - 550 per year and cost for simple prostatectomy/TURP is estimated at US$1100. For prostate cancer, individual direct costs from Europe range from 6,575 - 12,000 euros, £2818.00 UK and over U$12,000 - 20,000 in USA per annum. In Ghana, individual direct costs ranges, for radical prostatectomy and

    Radiological and pathological correlation of the full range of benign breast lesions, with emphasis on screen-detected lesions. Detailed discussion of risk assessment. Revised and updated edition, with a new chapter on gynaecomastia. Ideal aid to the management of patients with benign or indeterminate breast lesions in a multidisciplinary setting. The second edition of this book has been extensively revised and updated. There have been numerous scientific advances in the radiology, pathology and risk assessment of benign breast lesions since the publication of the first edition. The first edition concentrated on screen-detected lesions, which has since been rectified; new symptomatic and screen-detected lesions are discussed in the second edition and include: mastitis and breast abscesses, idiopathic granulomatous mastitis, diabetic mastopathy, phyllodes tumours, gynaecomastia and pseudoangiomatous stromal hyperplasia. The chapters on columnar cell lesions and mucocele-like lesions have been extensively updated. Where applicable, genetic analysis of the benign lesions, which is becoming part of personalised medicine in the field of breast cancer, has been included. The book also presents detailed analyses of the main models, such as the Gail Model, used to assess the subsequent risk of breast cancer in individuals. The current trend in the management of all cancers is preventative. Screening mammography detects early curable cancers as well as indeterminate lesions, the latter of which are invariably pathologically benign. The author has collated important benign lesions and, based on peer-reviewed publications, has documented the relative risk of subsequent cancer to allow the patient and the clinician to implement preventative measures where possible. This book will therefore serve as an essential component of multidisciplinary management of patients with symptomatic and screen-detected benign breast lesions.

We evaluated the safety and effectiveness of photoselective vaporization of the prostate (PVP in patients. We evaluated preoperative and perioperative parameters, functional outcomes, and adverse events up to 12 months postoperatively of patients on oral anticoagulation therapy undergoing PVP, and compared the results with patients who did not take anticoagulation therapy. A total of 89 patients who received photoselective vaporization laser for benign prostate hyperplasia from May 2006 to February 2011 in our hospital were enrolled in our study. The patients were divided into two groups based on whether or not they were taking oral aspirin; 23 (25.8% patients were taking aspirin derivatives (aspirin group, and 66 (74.2% were not taking aspirin derivatives (control group. The mean prostate volume (58.8 mL vs 51 mL; P = 0.16 and mean energy consumption (235,268 J vs 289,793 J; P = 0.097 were comparable between the aspirin group and control group. The average postoperative results of hemoglobin were 13.4 mg/dL for the aspirin group versus 13.9 mg/dL for the control group (P = 0.327. A significantly higher maximum flow rates and 80% improved post-void residual urine were noted during the followup. Postoperatively all variable showed significant improvement starting at month 1 of followup and remained improved for the 12 month followup. Postoperative complications were low and comparable between groups. PVP was characterized by excellent hemostatic

    To evaluate the vascular pattern of lymph nodes, and the usefulness of color Doppler sonogaphy in differentiating benign from malignant superficial lymphadenopathy. Twenty-six patients were pathologically and clinically confirmed to be suffering from benign reactive lymphadenitis and tuberculosis (n=16) or lymphoma and malignant lymphadenitis (n=10). Lymph node shape was assessed by the ratio of longitudinal diameter to transverse diameter(L/T), and patients were thus assigned to one of two groups : L/T{>=}2, or L/T<2. The hilar vascular pattern of lymph node was assessed by color Doppler sonography and classified as central, eccentric, or absent. On the basis of peripheral vascularity, patients were divided into three groups according to circumferental linear vascularity. An absence of peripheral vascularity was classified as grade 0. If less than half the periphery was covered by linear vascularity, a patient was assigned to as grade I, and if more than half was covered by a vessel, the classification was grade II. Statistically significant differences in L/T ratio were noted between malignant and benign node (p<.001). Of the 16 benign reactive nodes, 13 showed L/T{>=}2, and 3 L/T<2. while in nine of the ten malignant nodes, L/T<2 was noted. Among 16 benign reactive nodes, hilar vascularity was central in 13, eccentric in one, and absent in two. Among the ten malignant nodes, the corresponding totals were nil, four, and Six. The hilar vascular pattern showed statistically significant differentiation between malignant and benign node (p<.05). Among 16 benign reactive nodes, 13 were grade 0, two were grade I, and one was grade II, while among ten malignant nodes, two were grade 0 and eight were grade I. On the basis of vascular pattern, the difference between benign and malignant nodes was statistically significant (p<.05). L/T ratio<2, absent or eccentric hilar vascularity, and the presence of peripheral vascularity are suggestive of malignant lymph node. The

    Benign maxillo-mandibular tumors and cysts, which are relatively common findings on radiographs, namely the ubiquitous panoramic view, have to be dealt with by dentists on a daily basis. The aim of this study is to evaluate the panoramic radiographic findings pertaining to benign and tumoral lesions in the maxilla and mandible. Applying a case series method, panoramic images of 61 patients with cysts, benign tumors and tumor-like lesions in the jaws who were referred to Hamedan dental school between 2009 and 2011 were evaluated by two radiologists. They were both blind to histopathological results as well as the objectives of our study. Lesions were assessed based on their location, periphery, internal structure and impaction on the surrounding structures. Then the obtained data were analyzed using descriptive tables. Cysts were mostly more common in men despite the equal propensity of both genders to benign tumors. In contrast, women showed a higher frequency of tumor-like lesions. The most common site of involvement was the posterior mandible, with peri-apical tooth lesions as the most prevalent dental association. Radiographically, what we most encountered was unilocular radiolucency pertaining to cysts and benign tumors; nevertheless, tumor-like lesions tended to present with a well-defined radiopacity. Despite its known shortcomings, like every other diagnostic tool, panoramic radiography can contribute to the early detection of maxillary/mandibular lesions that in turn enable the dentist to devise an appropriate treatment plan.

    Endoscopic therapy by balloon dilation and placement of multiple large-bore plastic stents is the treatment of choice for benign biliary stricture. This approach is effective but it typically requires multiple endoscopic sessions given the short duration of stent patency. The endoscopic approach for treatment of bile leak involves the placement of a stent with or without biliary sphincterotomy. The self-expandable metal stent (SEMS) has traditionally been used for palliation of malignant biliary strictures given the long duration of stent patency owing to their larger stent diameter. Recently, SEMS has been used in a variety of benign biliary strictures and leaks, especially with the design of the covered self-expandable metal stent (CSEMS), which permits endoscopic-mediated stent removal. The use of CSEMS in benign biliary stricture could potentially result in a decrease in endoscopic sessions and it is technically easier when compared to placement of multiple plastic stents. However, complications such as cholecystitis due to blockage of cystic duct, stent migration, infection and pancreatitis have been reported. The potential subsegmental occlusion of contralateral intrahepatic ducts also limits the use of CSEMS in hilar stricture. Certain techniques and improvement of stent design may overcome these challenges in the future. Thus, CSEMS may be appropriate in only highly selected conditions, such as refractory benign biliary stricture, despite multiple plastic stent placement or difficult to treat bile duct stricture from chronic pancreatitis, and should not be used routinely. This review focuses on the use of fully covered self-expandable metal stent for benign biliary strictures and bile leaks.

    The benign paroxysmal positional vertigo is the most common disease in the group of peripheral vertigo. It's characterized by vertiginous sensation triggered by the positional changes of the head and usually lasts less than one minute. It is most frequently seen in middle-aged patients (40-50 years old) and in up 50% of cases we do not know the cause, so we refer to them as idiopathic benign paroxysmal positional vertigo. Because of the high incidence of benign paroxysmal positional vertigo in general population, it is of utmost importance to be aware of the differential diagnosis and to be able to treat this pathology with efficacy, because in most cases we can achieve excellent results performing specific and simple maneuvers.

    Full Text Available Benign paroxysmal positional vertigo is the cause of peripheral vertigo, which only takes seconds posed by certain head and body position and led to severe attacks of vertigo. Therefore, it is a disturbance that causes a continuous fear of fall and anxiety in some patients. Although benign paroxysmal positional vertigo is the most common cause of peripheral vertigo, it may cause unnecessary tests, treatment costs and the loss of labor due to the result of the delay in the diagnosis and treatment stages. Diagnosis and treatment of this disease is easy. High success rates can be achieved with appropriate repositioning maneuvers after taking a detailed medical history and accurate assessment of accompanying nystagmus. The aim of this paper was to review the updated information about benign paroxysmal positional vertigo. [Archives Medical Review Journal 2015; 24(4.000: 555-564

    Full Text Available Objectives: Benign paroxysmal positional vertigo is a common vestibular disorder and it may be idiopathic or secondary to some conditions such as surgery, but rare following laparoscopic surgery. Methods: We report two cases of benign paroxysmal positional vertigo secondary to laparoscopic surgery, one after laparoscopic cholecystectomy in a 51-year-old man and another following laparoscopic hysterectomy in a 60-year-old woman. Results: Both patients were treated successfully with manual or device-assisted canalith repositioning maneuvers, with no recurrence on the follow-up of 6 -18 months. Conclusions: Benign paroxysmal positional vertigo is a rare but possible complication of laparoscopic surgery. Both manual and device-assisted repositioning maneuvers are effective treatments for this condition, with good efficacy and prognosis.

    Report a case of malignant transformation of benign ear canal papillomatosis to malignant squamous cell carcinoma (SCC) of the temporal bone. A 73-year-old with papillomata involving the posterior and inferior walls of the right external auditory canal (EAC), which subsequently transformed into SCC. Radical mastoidectomy and excision of the tumor and then radical radiotherapy. Loco-regional disease control. Recovery of facial nerve function. Approximately 20 months post-treatment, the patient remains disease free. No recovery of facial nerve function. Malignant transformation of a benign EAC papilloma to SCC of the temporal bone has not been reported previously. The association of human papillomavirus with temporal bone SCC has been reported in small number of studies with human papillomavirus subtypes 16 and 18 isolated in a high proportion of cases. With the increased availability in genotyping, the question over whether there should be further genetic analysis of benign lesions to assess their susceptibility to malignant transformation has merit.

    2000-01-01

    The benign vascular tumors of bone represent a diverse group of tumors that can present with a broad spectrum of clinical signs and symptoms. They can also present a significant diagnostic challenge due to their widely variable radiographic imaging and histologic features. Some of the tumors manifest as clearly benign lesions with tissue-specific diagnostic imaging features, while others have non-specific imaging features that may simulate malignant neoplasm. This article will provide a review of the nomenclature and the characteristic radiographic and pathologic features of the benign vascular lesions of bone. The information will aid in improving our diagnostic accuracy and enhance our understanding of the biologic potential of this diverse group of osseous lesions. (orig.)

    Our purpose was to determine whether perfusion MR imaging can be used to differentiate benign and malignant meningiomas on the basis of the differences in perfusion of tumor parenchyma and/or peritumoral edema. A total of 33 patients with preoperative meningiomas (25 benign and 8 malignant) underwent conventional and dynamic susceptibility contrast perfusion MR imaging. Maximal relative cerebral blood volume (rCBV) and the corresponding relative mean time to enhance (rMTE) (relative to the contralateral normal white matter) in both tumor parenchyma and peritumoral edema were measured. The independent samples t-test was used to determine whether there was a statistically significant difference in the mean rCBV and rMTE ratios between benign and malignant meningiomas. The mean maximal rCBV values of benign and malignant meningiomas were 7.16{+-}4.08 (mean{+-}SD) and 5.89{+-}3.86, respectively, in the parenchyma, and 1.05{+-}0.96 and 3.82{+-}1.39, respectively, in the peritumoral edema. The mean rMTE values were 1.16{+-}0.24 and 1.30{+-}0.32, respectively, in the parenchyma, and 0.91{+-}0.25 and 1.24{+-}0.35, respectively, in the peritumoral edema. The differences in rCBV and rMTE values between benign and malignant meningiomas were not statistically significant (P>0.05) in the parenchyma, but both were statistically significant (P<0.05) in the peritumoral edema. Perfusion MR imaging can provide useful information on meningioma vascularity which is not available from conventional MRI. Measurement of maximal rCBV and corresponding rMTE values in the peritumoral edema is useful in the preoperative differentiation between benign and malignant meningiomas. (orig.)

    This paper deals with application of fuzzy intelligent systems in diagnosing severity level and recommending appropriate therapies for patients having Benign Prostatic Hyperplasia. Such an intelligent system can have remarkable impacts on correct diagnosis of the disease and reducing risk of mortality. This system captures various factors from the patients using two modules. The first module determines severity level of the Benign Prostatic Hyperplasia and the second module, which is a decision making unit, obtains output of the first module accompanied by some external knowledge and makes an appropriate treatment decision based on its ontology model and a fuzzy type-1 system. In order to validate efficiency and accuracy of the developed system, a case study is conducted by 44 participants. Then the results are compared with the recommendations of a panel of experts on the experimental data. Then precision and accuracy of the results were investigated based on a statistical analysis.

    2009-05-01

    Benign symmetric lipomatosis (Madelung disease) is a rare disorder of unknown etiology characterized by diffuse growth of unencapsulated lipomas predominantly in the head, neck and shoulder region. Involvement of the tongue has been previously described in only five cases. A 49-year-old man with alcoholic liver cirrhosis presented with an 11-year history of benign symmetric lipomatosis complaining of increasing dysphagia, dysarthria and hoarseness. Clinical intraoral examination revealed asymmetric, globular, firm, circumscribed masses on both borders of the tongue. During surgery, the masses seemed encapsulated from surrounding muscles and could easily be extirpated. However, "satellite fat cells" became obvious, which might give rise to the development of new lipomas.

    Benign multicystic peritoneal mesothelioma is an uncommon lesion arising from the peritoneal mesothelium. It is asymptomatic or presents with unspecific symptoms. Imaging techniques may reveal it, however the final diagnosis can only be made by histopathology. Surgery is the only effective treatment considering its high recurrence rate. We report a 19 years old male with Crohn’s disease. Due to persistent abdominal pain, an abdominal magnetic resonance imaging was performed, showing a complex cystic mass in the lower abdomen. The patient underwent surgery and the lesion was completely resected. The pathological study reported a benign multicystic peritoneal mesothelioma.

    The aim of this study was to evaluate the physiologic and benign F-18 fluorodeoxyglucose (FDG) avid foci in patients with breast cancer. On 309 F-18 FDG PET/CT scans of 241 women with breast cancer, the hypermetabolic lesions compared with the surrounding normal region were evaluated retrospectively. Available reports of other relevant radiological imaging medical records, and follow-up PET/CT were reviewed for explanations of the abnormal uptake. Among the 70 physiologic foci, muscular uptake of the lower neck following the surgical and/or radiation therapy of ipsilateral breast (29%), hypermetabolic ovaries (16%) and uterine (10%) uptake during the ovulatory and menstrual phases during the normal menstrual cycle were identified, and also hypermetabolic brown fat in cold-induced thermogenesis (7%), non-specific bowel uptake (35%) were observed. Among the 147 benign lesions, sequelae of the chest wall and breasts following surgical and/or radiation therapy, were often observed (27%). Hypermetabolic thyroid glands were noted as adenomas and chronic thyroiditis (18%). Reactive hyperplasia of cervical or mediastinal lymph nodes (32%), degenerative osteoarthritis and healed fractures (15%), hypermetabolic benign lung lesions (6%) were observed. Altered physiologic and benign F-18 FDG uptake in the cervical muscle and chest wall following ipsilateral breast surgery or radiotherapy were common, and also normal physiologic uptake in ovary and uterus, brown fat, thyroid were considered as predominant findings in women patients with breast cancer. Knowledge of these findings might aid in the interpretation of FDG PET/CT in patients with breast cancer

    The authors have used transurethral microwave thermotherapy in the treatment of benign prostatic hyperplasia since October 1991. Irreversible cell damage occurs when the microwaves heat the periurethral prostatic tissue. The urethra is simultaneously cooled and is not destroyed during treatment. The patients are not hospitalized. Transurethral microwave thermotherapy is performed under local anaesthesia, no other form of analgesia has been found necessary. Included were patients with symptomatic prostatic obstruction who would otherwise have received operative or pharmacologic treatment. Patients with high residual urine, large middle lobe, urethral stricture, prostatic cancer, decreased renal function, urinary infection or metal implants were excluded. It was observed a marked improvement in the Madsen symptom score after transurethral microwave thermotherapy. The score decreased from 12 before treatment to five after six weeks and 4.6 after six moths. Flow increased from 8.9 to 9.7 ml/s. There was a significant reduction in the residual urine from 102 ml preoperatively to 69 ml after six months. The volume of the prostate was only slightly reduced after transurethral microwave thermotherapy. Postoperative edema caused urinary retention in 13% of the patients. Two patients required transurethral resection of the prostata. 5 refs., 3 figs., 1 tab.

    A total of 28 patients with symptomatic bladder outlet obstruction due to benign prostatic hyperplasia were treated by visual laser coagulation (VLAP) performed with the Myriadlase side-firing neodymium: YAG laser fibre at 40 watts power. The treatment was performed as an outpatient procedure using intraurethral gel anaesthesia and light intravenous sedation and analgesia. Prostatic volume was 32 g and 650 joule per gram prostatic tissue was administered. The patients were evaluated at mean 9.2 weeks. The mean operative time was 34 minutes. The procedure was very gentle, all patients tolerated it well and there was no bleeding. Most patients experienced some dysuria for three to four weeks after the procedure, two had severe symptoms. Two patients remained in retention and required transurethral resection. The rest expressed subjective satisfaction with the results. Peak urinary flow increased from mean 9.0 ml/sec preoperatively to 15.4 ml/sec; a mean increase of 78%. One patients developed clinical urinary tract infection. There were no other complications of clinical significance. 19 refs., 1 fig.

    Full Text Available Purpose: To evaluate the accuracy of benign core biopsy of probably benign breast lesions (category 3 2 cm or larger on the basis of excisional biopsy and long-term follow-up. Methods: We retrospectively reviewed 146 category 3 lesions in 146 patients 2 cm or larger which were diagnosed as benign by ultrasound (US-guided core biopsy. Patients were initially diagnosed as benign at core needle biopsy and then followed up with excisional biopsy (surgical excision, n=91; US-guided vacuum assisted excision, n=35 or breast ultrasonography (n=20. Results: Of the 126 patients who underwent surgical excision or US-guided vacuum-assisted excision, 114 patients were diagnosed with benign lesions, 10 patients with borderline lesions (benign phyllodes tumor, and two patients with malignant phyllodes tumors. The probabilities of lesions being benign, borderline and malignant were 91.8% (134/146, 6.8% (10/146, and 1.4% (2/146, respectively. Of 13 patients who had growing masses on follow-up ultrasonography, three (23.1% were non-benign (two benign phyllodes tumors and one malignant phyllodes tumor. Conclusion: US-guided core needle biopsy of probably benign breast mass 2 cm or larger was accurate (98.6% enough to rule out malignancy. But, it was difficult to rule out borderline lesions even when they were diagnosed as benign.

The combination of daily tadalafil and an α-blocker has also demonstrated benefit. This paper addresses combination therapy with daily tadalafil and finasteride for the treatment of BPH-LUTS. Our results demonstrate that use of tadalafil and finasteride represents a logical extension of combination therapies. We analyze a landmark study by Casabé et al that demonstrates improved voiding symptoms as assessed by International Prostate Symptom Scores with a combination of tadalafil and finasteride compared with finasteride and placebo. Study patients had moderate to severe LUTS and prostate volumes >30 g. The additional benefit of improved erectile function as assessed by International Index of Erectile Function-erectile function domain scores with the addition of tadalafil was a secondary benefit. We propose that the ideal patient for combination therapy with tadalafil and finasteride has a prostate volume >30 g and desires additional benefit over monotherapy. For these men, improved erectile function without sexual side effects was a secondary benefit.Keywords: benign prostatic hyperplasia, lower urinary tract symptoms, tadalafil, finasteride

  8. Mammary radioiodine accumulation due to functional sodium iodide symporter expression in a benign fibroadenoma

    The sodium iodide symporter (NIS) has been characterized to mediate the active transport of iodide not only in the thyroid gland but also in various non-thyroidal tissues, including lactating mammary gland and the majority of breast cancers, thereby offering the possibility of diagnostic and therapeutic radioiodine application in breast cancer. In this report, we present a 57-year-old patient with multifocal papillary thyroid carcinoma, who showed focal radioiodine accumulation in a lesion in the right breast on a posttherapy 131 I scan following radioiodine therapy. CT and MR-mammography showed a focal solid lesion in the right breast suggestive of a fibroadenoma, which was confirmed by histological examination. Immunostaining of paraffin-embedded tumor tissue sections using a human NIS antibody demonstrated NIS-specific immunoreactivity confined to epithelial cells of mammary ducts. In conclusion, in a thyroid cancer patient we identified a benign fibroadenoma of the breast expressing high levels of functionally active NIS protein as underlying cause of focal mammary radioiodine accumulation on a posttherapy 131 I scan. These data show for the first time that functional NIS expression is not restricted to lactating mammary gland and malignant breast tissue, but can also be detected in benign breast lesions, such as fibroadenomata of the breast

    2015-09-01

    Full Text Available Photodynamic therapy (PDT uses a photosensitizer, light energy, and molecular oxygen to cause cell damage. Cells exposed to the photosensitizer are susceptible to destruction upon light absorption because excitation of the photosensitizing agents leads to the production of reactive oxygen species and, subsequently, direct cytotoxicity. Using the intrinsic cellular heme biosynthetic pathway, topical PDT selectively targets abnormal cells, while preserving normal surrounding tissues. This selective cytotoxic effect is the basis for the use of PDT in antitumor treatment. Clinically, PDT is a widely used therapeutic regimen for oncologic skin conditions such as actinic keratosis, squamous cell carcinoma in situ, and basal cell carcinoma. PDT has been shown, under certain circumstances, to stimulate the immune system and produce antibacterial, and/or regenerative effects while protecting cell viability. Thus, it may be useful for treating benign skin conditions. An increasing number of studies support the idea that PDT may be effective for treating acne vulgaris and several other inflammatory/infective skin diseases, including psoriasis, rosacea, viral warts, and aging-related changes. This review provides an overview of the clinical investigations of PDT and discusses each of the essential aspects of the sequence: its mechanism of action, common photosensitizers, light sources, and clinical applications in dermatology. Of the numerous clinical trials of PDT in dermatology, this review focuses on those studies that have reported remarkable therapeutic benefits following topical PDT for benign skin conditions such as acne vulgaris, viral warts, and photorejuvenation without causing severe side effects.

    Benign hereditary chorea (BHC) (MIM 118700) is an autosomal dominant movement disorder. The early onset of symptoms (usually before the age of 5 years) and the observation that in some BHC families the symptoms tend to decrease in adulthood suggests that the disorder results from a developmental

    The radiation oncologist encounters the critically ill immunosuppressed patient in four settings. First, the newly diagnosed cancer patient presents for initial evaluation and treatment, with immunosuppression from the cancer itself, malnutrition, concomitant infectious disease, prior drug or alcohol abuse or other medical problems. Second, the previously treated cancer patient presents with metastatic or recurrent primary cancer causing local symptoms. Immune dysfunction in this setting may be due to prior chemotherapy and/or radiation as well as any of the original factors. Third, the patient previously treated with radiation presents with a life-threatening problem possibly due to complications of prior therapy. In this setting, the radiation oncologist is asked to evaluate the clinical problem and to suggest whether radiation might be causing part or all of the problem and what can be done to treat these sequelae of radiation. Fourth, the patient with a benign diagnosis (not cancer) is seen with a problem potentially emeliorated by radiation (e.g., kidney transplant rejection, preparation for transplant, or intractable rheumatoid arthritis). This chapter reviews these four issues and presents clinical and radiobiologic principles on which recommendations for therapy are based

    We assessed rates of oophorectomy during benign hysterectomy around the release of the American College of Obstetricians and Gynecologists 2008 practice bulletin on prophylactic oophorectomy, and evaluated predictors of inappropriate premenopausal oophorectomy. A cross-sectional administrative database analysis was performed utilizing the California Office of Statewide Health Planning Development Patient Discharge Database for years 2005 to 2011. After identifying all premenopausal women undergoing hysterectomy for benign conditions, International Classification of Diseases (ICD)-9 diagnosis codes were reviewed to create a master list of indications for oophorectomy. We defined appropriate oophorectomy as cases with concomitant coding for ovarian cyst, breast cancer susceptibility gene carrier status, and other diagnoses. Using patient demographics and hospital characteristics to predict inappropriate oophorectomy, a logistic regression model was created. We identified 57,776 benign premenopausal hysterectomies with oophorectomies during the period studied. Of the premenopausal oophorectomies, 37.7% (21,783) were deemed "inappropriate" with no documented reason for removal. The total number of premenopausal inpatient hysterectomies with oophorectomy decreased yearly (12,227/y in 2005 to 5,930/y in 2011). However, the percentage of inappropriate oophorectomies remained stable. In multivariate analysis, Hispanic and African American ethnicity/race associated with increased odds of inappropriate oophorectomy (P Urban and at low Medi-Cal utilization hospitals showed increased odds of inappropriate oophorectomy. In premenopausal women undergoing benign hysterectomy, over one-third undergo oophorectomy without an appropriate indication documented. The rate of inappropriate oophorectomy in California has not changed since the 2008 American College of Obstetricians and Gynecologists guidelines. Whereas the absolute number of inpatient hysterectomies for benign

    Fine-needle aspiration cytology is the standard technique to diagnose thyroid pathologies. However, this method results in a high percentage of inconclusive and false negatives. The use of time-resolved fluorescence techniques to detect biochemical composition and tissue structure alterations could help to develop a portable, minimally invasive, and nondestructive method to assist during surgical procedures. This study aimed to use fluorescence lifetimes to differentiate healthy and benign tissues from malignant thyroid tissue. The thyroid tissue was excited at 298-300 nm and the fluorescence decay registered at 340 and 450 nm. We observed fluorescence lifetimes at 340 nm emission of 0.80±0.26 and 3.94±0.47 ns for healthy tissue; 0.90±0.24 and 4.05±0.46 ns for benign lesions; and 1.21±0.14 and 4.63±0.25 ns for malignant lesions. For 450 nm emissions, we obtain lifetimes of 0.25±0.18 and 3.99±0.39 ns for healthy tissue, 0.24±0.17 and 4.20±0.48 ns for benign lesions, 0.33±0.32 and 4.55±0.55 ns for malignant lesions. Employing analysis of variance, we differentiate malignant lesions from benign and healthy tissues. In addition, we use quadratic discriminant analysis to distinguish malignant from benign and healthy tissues with an accuracy of 76.1%, sensitivity of 74.7%, and specificity of 83.3%. These results indicate that time-resolved fluorescence can assist medical evaluation of thyroid pathologies during surgeries.

  14. Evaluation of a potential parathyroid dysfunction under treatment with radioactive iodine of benign thyroid diseases; Pruefung einer potentiellen strahleninduzierten Nebenschilddruesenfunktionsstoerung waehrend einer Radioiodtherapie benigner Schilddruesenerkrankung

    The intention of the present thesis was the evaluation of a potential parathyroid dysfunction under treatment with radioactive iodine of benign thyroid diseases. It was to be examined whether a change in the parathyroid function would arise within the first week on treatment. So far there are some minor studies existing describing significant changes in the parathyroid hormone serum level within the first months after radioactive iodine therapy of benign and malignant thyroid diseases. Moreover, it is a fact that external beam-radiotherapy can induce neoplasia and that the risk for the subsequent development of primary hyperparathyroidism doubles or triples after external beam-radiotherapy of the head and neck. Up to now, however, an increased incidence for primary hyperparathyroidism following treatment with radioactive iodine ({sup 131}I) could not be proved. At the department of nuclear medicine of the university hospital Giessen-Marburg GmbH, location Marburg, a prospective cohort study was executed on radioactive iodine therapy of benign thyroid diseases with 105 probands (75 women / 30 men, mean age 60.62 ± 14.3 years). According to their thyroid diseases these 105 probands were classified into following subgroups: thyroid adenoma with 23 patients, multifocal thyroid autonomy with 8 patients, disseminated thyroid autonomy with 37 patients as well as the subgroup Graves' hyperthyroidism (without Graves' ophtalmopathy) and accordingly Graves' disease (with Graves' ophtalmopathy) with 37 patients. The serum level of the intact parathyroid hormone was determined directly before starting the radioactive iodine therapy on the admission day and on day 1, 3 and 5 of the radioactive iodine therapy as well as at the ambulant follow-up examination one month after the start of the therapy. In case of 99 of 105 probands the serum level of parathyroid hormone declined on treatment with {sup 131}I with its nadir on day 3 of therapy (decline by 15.71 ng

    We lately reported the cases of patients complaining positional vertigo whose nystagmic pattern was that of a peripheral torsional vertical positional down beating nystagmus originating from a lithiasis of the non-ampullary arm of the posterior semicircular canal (PSC). We considered this particular pathological picture the apogeotropic variant of PSC benign paroxysmal positional vertigo (BPPV). Since the description of the pilot cases we observed more than 150 patients showing the same clinical sign and course of symptoms. In this paper we describe, in detail, both nystagmus of apogeotropic PSC BPPV (A-PSC BPPV) and symptoms reported by patients trying to give a reasonable explanation for these clinical features. Moreover we developed two specific physical therapies directed to cure A-PSC BPPV. Preliminary results of these techniques are related. PMID:26557364

    X-ray therapy of painful and inflammatory changes in joints and adjacent structures was very common in Sweden during the period from 1940 until the beginning of the 1960:s. These patients comprise a comprehensive material pertinent for epidemiological studies. The present study deals with a cohort of c. 27,400 patients from 3 hospitals in northern Sweden, who 1950 - 1964 received x-ray treatment for benign painful conditions. The distribution of the absorbed dose in the red marrow was estimated. The average mean absorbed dose in red bone marrow was 0.4 Gy for the total cohort. The number of leukaemia cases observed in the cohort was obtained from the Swedish Cancer Register for the period 1958 - 1995. The study indicates a slightly increased leukaemia risk with borderline statistical significance in the highest dose group. (au)

    Benign prostatic hyperplasia (BPH) is a nonmalignant pathological enlargement of the prostate, which occurs primarily in the transitional zone. BPH is highly prevalent and is a major cause of lower urinary tract symptoms in aging males, although there is no direct relationship between prostate volume and symptom severity. The progression of BPH can be quantified by measuring the volumes of the whole prostate and its zones, based on image segmentation on magnetic resonance imaging. Prostate volume determination via segmentation is a useful measure for patients undergoing therapy for BPH. However, prostate segmentation is not widely used due to the excessive time required for even experts to manually map the margins of the prostate. Here, we review and compare new methods of prostate volume segmentation using both manual and automated methods, including the ellipsoid formula, manual planimetry, and semiautomated and fully automated segmentation approaches. We highlight the utility of prostate segmentation in the clinical context of assessing BPH.

  19. Androgen receptor and immune inflammation in benign prostatic hyperplasia and prostate cancer

    2014-01-01

    Both benign prostatic hyperplasia (BPH) and prostate cancer (PCa) are frequent diseases in middle-aged to elderly men worldwide. While both diseases are linked to abnormal growth of the prostate, the epidemiological and pathological features of these two prostate diseases are different. BPH nodules typically arise from the transitional zone, and, in contrast, PCa arises from the peripheral zone. Androgen deprivation therapy alone may not be sufficient to cure these two prostatic diseases due to its undesirable side effects. The alteration of androgen receptor-mediated inflammatory signals from infiltrating immune cells and prostate stromal/epithelial cells may play key roles in those unwanted events. Herein, this review will focus on the roles of androgen/androgen receptor signals in the inflammation-induced progression of BPH and PCa. PMID:26594314

    Results of radiotherapy in 21 patients who had been treated for intracranial meningioma from April 1975 to March 1993 at Tokyo Metropolitan Komagome Hospital are presented. All patients were treated with 4 MV X-rays using conventional fractionation. The median tumor dose was 54.4 Gy (range 30 Gy to 70 Gy). Radiotherapy was delivered by conformation technique in 11, parallel opposed field in four and three ports technique in two. Of 21 meningiomas, 13 were histologically malignant and 8 were benign. The median follow-up period was 63 months. Overall survival rate at 5 years was 71% for benign and 63% for malignant meningiomas; the 5-year progression-free survival rates were 25% and 30%, respectively. Eight of 21 patients received 60 Gy or more, and the remaining 13 received less than 60 Gy. The 5-year overall survival rates for these two groups were 43% and 83% (p<0.05), respectively. Ten of 21 patients were treated with post-operative radiotherapy as initial treatment and eleven of 21 patients were treated with salvage therapy with or without surgical excision for recurrent lesions. The 5-year survival rates and progression-free survival rates of these two groups showed no significant differences. From analysis of the clinical course of the salvage therapy group, radiotherapy may prolong survival time and delay further tumor recurrence. According to the present study, radiotherapy (doses of 55 Gy to 60 Gy) after primary resection and at the time of recurrence are equally effective for prolongation of survival and delay of further tumor recurrence.

    With the advent of targeted therapies, expression of sex hormone receptors and HER-2 in salivary gland tumors (SGTs) is of clinical interest. Previous reports of estrogen (ER) and progesterone (PR) receptor expression have varied. Androgen receptor (AR) and HER-2 overexpression are frequently reported in salivary duct carcinoma (SDC), but have not been studied systematically in other SGTs. This study examines ER, PR, AR, and HER-2 expression in SGTs. Immunohistochemistry for ER, PR, AR, and HER-2 was performed on 254 SGTs (134 malignant). ER, PR, and AR expression was scored using Allred system. HER-2 expression was scored using Dako HercepTest guidelines. FISH for HER-2 amplification was performed on select cases with HER-2 overexpression (2-3+). No SGT demonstrated strong expression of ER or PR. Combined strong AR and HER-2 expression was seen in 22 carcinomas: 14/25 SDC, 3/16 poorly differentiated, two oncocytic, and one each carcinoma ex pleomorphic adenoma, squamous cell, and intraductal carcinoma. Eighteen additional high grade carcinomas had HER-2 overexpression with absent, weak, or moderate AR expression; eight high grade carcinomas had isolated strong AR expression with 0-1+ HER-2 staining. Of 15 tested cases, six demonstrated HER-2 amplification by FISH, all of which had 3+ immunoreactivity. Neither benign nor malignant SGTs had strong expression of ER or PR. None of the benign SGTs overexpressed AR or HER-2. Coexpression of AR and HER-2 should not define SDC, but immunostaining should be considered in high grade salivary carcinomas, as some show overexpression and may benefit from targeted therapy.

    Objective: To study the effect of radioactive nuclide 90 Sr/ 90 Y treatment in patients with benign prostatic hypertrophy (BPH). Methods: Sixty patients with BPH were treated with a course of transurethral radioactive nuclide 90 Sr/ 90 Y therapy. Results: The severity of BPH was assessed with four parameters: maximal flow rate (MFR), volume of residual urine (VRU), international prostatic symptom score (IPSS) and volume (size) of prostate. In this series, the total effective rate was 93.33% with no treatment- related mortality. Favorable changes of the parameters after a course of radioactive nuclide therapy were significant. Conclusion: Radioactive nuclide 90 Sr/ 90 Y therapy for patients with BPH was safe, easily performed and quite effective. This procedure is worth popularizing in appropriate patients. (authors)

    Full Text Available Background: Phyllodes tumors are group of biphasic fibroepithelial tumors of the breast of varying malignant potential, ranging from benign tumors to fully malignant sarcomas. According to the Egyptian National Cancer Institute, female malignant cases showed appreciable increase in the recent time period for breast cancer with the malignant phyllodes tumors representing 0.41% of cases in the year 2003-2004. Aims: This is an immunohistochemical study to compare CD10 expression in benign, borderline, and malignant phyllodes tumors, in order to highlight its diagnostic and prognostic values. Materials and Methods: This study conducted 34 Egyptian female cases of phyllodes tumors of different grades to be studied histologically and immunohistochemically using antibodies against CD10. Statistical Analysis: The Chi-square test was used to determine differences in CD10 expression between benign, borderline, and malignant tumors. One-way ANOVA test was used to determine whether the difference was significant. Significance was established at P<0.05. Results: In the 24 cases of benign phyllodes tumors, only four cases (16.7% showed positive CD10 reactivity. Three cases (60% out of five borderline phyllodes tumors showed positive CD10 reactivity, while four (80% out of five cases of malignant phyllodes tumors showed positive CD10 staining. Conclusion: From these highly significant results, we believe that there is a strong correlation between CD10 expression and tumor grade, which could be an important observation that may have both diagnostic and prognostic implications as well as promising potential target for development of novel therapies.

    Paratesticular cysts with benign epithelial proliferations (BEPs) are rare. Only 10 cases were found in a series of 431 paratesticular cysts and were classified as follows: cystadenoma, 5; papilloma, 2; and hamartoma, 3. Four cystadenomas showed multiple papillae lined by CD10+ epithelial cells with hyperchromatic nuclei. The remaining lesion showed areas with a microcystic, glandular, cribriform pattern, with small, benign glands without atypia. Urothelial papilloma presented BEPs with cytokeratin (CK) 7+ and CD10+ and CK20- umbrella-like cells. The mural papilloma was lined by proliferative cylindrical cells exhibiting strong CK7 and CD10 expression. The 3 Wolffian hamartomas were characterized by strongly CD10+ epithelium surrounded by smooth muscle cells. The consistent CD10 expression in BEPs of paratesticular cysts suggests a Wolffian origin. The differential diagnosis of paratesticular cysts with BEP vs metastatic prostatic and primary borderline or malignant tumors is discussed.

    Bone marrow oedema is associated with a wide variety of pathological processes including both benign and malignant bone tumours. This imaging finding in relation to intraosseous tumours can aid in providing a more focused differential diagnosis. In this review, we will discuss the MR imaging of bone marrow oedema surrounding intraosseous neoplasms. The different pulse sequences used in differentiating underlying tumour from surrounding oedema are discussed along with the role of dynamic contrast enhanced MRI. Benign lesions commonly associated with bone marrow oedema include osteoid osteoma, osteoblastoma, chondroblastoma and Langerhan's cell histiocytosis. Metastases and malignant primary bone tumours such as osteosarcoma, Ewing's sarcoma and chondrosarcoma may also be surrounded by bone marrow oedema. The imaging findings of these conditions are reviewed and illustrated. Finally, the importance of bone marrow oedema in assessment of post chemotherapeutic response is addressed.

  12. Malondialdehyde in benign prostate hypertrophy: a useful marker?

    2003-01-01

    Full Text Available Benign prostate hypertrophy (BPH is the most common benign tumor in men due to obstruction of the urethra and, finally, uremia. Malondialdehyde (MDA is a product derived from peroxidation of polyunsaturated fatty acids and related esters. Evaluation of MDA in serum represents a non-invasive biomarker of oxidative stress. Prostate-specific antigen (PSA is a sensitive marker for prostatic hypertrophy and cancer. We analyzed MDA serum levels to evaluate the oxidative stress in BPH. To this end, 22 BPH patients and 22 healthy donors were enrolled. Data show an increase of MDA level in BPH patients and a positive correlation between PSA and MDA levels. In conclusion, we describe a previously unknown relationship between PSA and MDA as an index of inflammation and oxidative stress in BPH.

  13. Indications for surgical resection of benign pancreatic tumors

    International Nuclear Information System (INIS)

    Isenmann, R.; Henne-Bruns, D.

    2008-01-01

    Benign pancreatic tumors should undergo surgical resection when they are symptomatic or - in the case of incidental discovery - bear malignant potential. This is the case for the majority of benign pancreatic tumors, especially for intraductal papillary mucinous neoplasms or mucinous cystic adenomas. In addition, resection is indicated for all tumors where preoperative diagnostic fails to provide an exact classification. Several different operative techniques are available. The treatment of choice depends on the localization of the tumor, its size and on whether there is evidence of malignant transformation. Partial duodenopancreatectomy is the oncological treatment of choice for tumors of the pancreatic head whereas for tumors of the pancreatic tail a left-sided pancreatectomy is appropriate. Middle pancreatectomy or duodenum-preserving resection of the pancreatic head is not a radical oncologic procedure. They should only be performed in cases of tumors without malignant potential.

    2016-01-01

    The purpose of this case report is to present the cases of 2 boys with benign paroxysmal positional vertigo (BPPV). Patient A (11 years old) and Patient B (9 years old) had complaints of vertigo with position changes. Both exhibited left torsion upbeating nystagmus in the left Dix-Hallpike (DH) test and complaints of vertigo with reproduction of their symptoms, indicating BPPV. Both were treated with a left canalith repositioning maneuver and reported decreased incidence of positional vertigo upon reevaluation. Scores on the Dizziness Handicap Inventory and the Visual Analog Scale for Dizziness decreased after treatment for 1 of the boys. Benign paroxysmal positional vertigo is considered rare in children. Migraines may also cause vertigo. Differential diagnosis in these cases was made by performing the DH test. Children with vertigo should be screened for BPPV through use of history taking, and the DH test.

    2015-01-01

    Full Text Available With increased exposure of patients to routine imaging, incidental benign intrathoracic masses are frequently recognized. Most have classical imaging features, which are pathognomonic for their benignity. The aim of this pictorial review is to educate the reader of radiological features of several types of intrathoracic masses. The masses are categorized based on their location/origin and are grouped into parenchymal, pleural, mediastinal, or bronchial. Thoracic wall masses that invade the thorax such as neurofibromas and lipomas are included as they may mimic intrathoracic masses. All examples are illustrated and include pulmonary hamartoma, pleural fibroma, sarcoidosis, bronchial carcinoid, and bronchoceles together with a variety of mediastinal cysts on plain radiographs, computed tomography (CT and magnetic resonance imaging (MRI. Sometimes a multimodality approach would be needed to confirm the diagnosis in atypical cases. The study would include the incorporation of radionuclide studies and relevant discussion in a multidisciplinary setting.

    Full Text Available PURPOSE: To present rare benign orbital tumors with bone destruction in children who could not be diagnosed pre-surgically and may simulate malignant ones. METHODS: A retrospective review of cases. Clinical, operative and pathological records in all children with a diagnosis of benign orbital tumors who showed remarkable bone destruction at a tertiary Ophthalmic Center in China between Jan 1, 2000 and Dec 31, 2009 were reviewed. All patients had definitive histopathologic diagnosis. RESULTS: Eight patients with benign orbital tumors showed obvious bone destruction, including six cases of eosinophilic granuloma, one case of leiomyoma and one case of primary orbital intraosseous hemangioma. Among them, three patients were females and five patients were males. Tumors were unilateral in all cases, with both the right and left side affected equally. Age ranged from 3 to 7 years (mean 4.1 years. Symptom duration ranged from 1 to 5 weeks (mean 4.8 weeks. Eyelid swelling and palpable mass were the most common complaint. There was no evidence for multifocal involvement in cases with eosinophilic granuloma. Among six patients with eosinophilic granuloma, two were treated with low dose radiation (10 Gy, three received systemic corticosteroid and one was periodically observed only after incisional biopsy or subtotal curettage. There was no postoperative therapeutic intervention in the two patients with leiomyoma and intraosseous hemangioma. All eight patients regained normal vision without local recurrence after a mean follow-up time of 32.8 months. CONCLUSION: Benign orbital tumors such as isolated eosinophilic granuloma, leiomyoma and primary orbital intraosseous hemangioma may show remarkable bone destruction.

    Benign paroxysmal positional vertigo is one of the most common vestibular disorders, with a lifetime prevalence of 2.4%. This study aimed to assess age, gender, lesion type and site, association with other vestibular diseases, progression and recurrence in a Portuguese population. This was a retrospective observational study of 101 patients diagnosed with benign paroxysmal positional vertigo by the same senior doctor, in a tertiary academic hospital, between January 2009 and May 2011. A total of 101 cases were pooled, with a mean age of 56.57±15.33 years (15-90 years). From these, 72.3% were women. The posterior canal was affected in 72.3%, the lateral in 24.7%, the anterior in 2% and multiple canals in 1%. Unilateral canal and left labyrinth involvement were more frequent. The therapeutic maneuver used most was Epley's. Recurrence was observed in 10.9% of the cases. It was idiopathic in 83.2% of cases. No association was found between the number of maneuvers necessary to treat benign paroxysmal positional vertigo and etiology. Benign paroxysmal positional vertigo is more frequent in female subjects, in the 6th decade and involves preferably the posterior semicircular canal of the right labyrinth. In most cases it is idiopathic and treatment with repositioning maneuvers has a mean success of 90%. Our results were in accordance with the literature; nevertheless, in this study the left labyrinth was most affected and the follow-up period was variable.

    Enhanced recovery programs (ERPs) are evidence-based protocols designed to improve functional rehabilitation after surgery. ERPs have gained widespread acceptance in many surgical disciplines, and their use leads to significant improvements in patient outcomes while reducing hospital length of stay (LOS). There remains a paucity of data on the use of ERPs in benign gynecologic surgery. The purpose of this review was to evaluate current literature on the use of ERP concepts in benign gynecologic surgery. A systematic search of PubMed, CINAHL, Web of Science, and the Cochrane databases was conducted, cross-referencing search terms related to gynecologic surgery and ERP concepts. The search was limited to publications available in English. Studies published prior to 2000, and those involving gynecologic oncology, nonadult patients, and outpatient surgery were excluded. Nine studies were included in the analysis. Due to heterogeneity of the included studies, no statistical pooling was possible and comparison between studies was limited to their respective themes. Primary study outcomes included LOS, postoperative nausea and vomiting (PONV), pain management, patient satisfaction, and hospital costs. Five studies investigated ERPs, two evaluated measures to improve PONV, and four focused on unique aspects of pain management. Across the studies, ERPs that focused on the patients' basic symptoms and recovery were found to have equal, if not better, outcomes than standard practice. This integrative review supports the implementation of ERPs in benign gynecologic surgery. The results showed that the use of ERPs decreased LOS, improved pain scores, and reduced hospital costs, without increasing perioperative complications. We suggest additional randomized controlled trials of ERP concepts in benign gynecologic surgery to support their more widespread use and application.

    The problems of cystic tumors in adolescence lie in the danger of permanent fracture and in the readiness of the cyst to recur with increased growth. In recent years, therefore, we have turned to resection with subsequent closure using a chip of rib or fibula for benign cystic tumors. Experience so far is presented, the freedom from recurrence at the time of follow-up being particularly emphasized.

    Full text: The thyroid ability to store and concentrate iodine is of importance for radioiodine therapy in thyroid cancer. It is known that a normal thyroid contains 2-20 mg iodine while the information regarding malignant thyroid tissue is scarce. The purpose of this study was to investigate the iodine concentration in benign compared to malignant tissue. Methods: Thyroid tissue samples from healthy patients and from patients with papillary cancer were collected and frozen in connection with surgery. For the thyroid cancer patients, tissue was taken from both benign and malignant tissue. The iodine concentration was analysed with an XRF system consisting of a 241-Am source and an HPGe detector. When irradiating iodine containing tissue, characteristic X-rays are emitted. That radiation is detected with the strength of the detected signal being proportional to the amount of iodine in the sample. SIMS was used on glutaraldehyde fixed tissue as a histological tool for quantification and localization of iodine by sputtering and analysis of secondary ions. Results: The iodine concentration in benign tissue is considerably higher than in malignant samples. XRF measurements showed a medium iodine concentration in healthy thyroid tissue of 0.5 mg/mL. For the cancer patients, the iodine concentration was 0.3 mg/mL in benign tissue while no iodine could be detected in the malignant samples. These findings were consistent with the results from the SIMS investigation that gave a 100 times lower iodine concentration in malignant than in benign tissue. SIMS also showed that the iodine in benign tissue was predominantly located in the follicle lumen, while in the cancer cells low iodine concentration was found intra cellular as well as in the lumen. Conclusion: Iodine concentration in tissue from papillary cancer can be 100 times lower than in normal thyroid tissue. This is in accordance with the empirical knowledge that thyroid cancer should need about 100 times higher activity

    Full Text Available Surgical resection is usually prefered for the treatment of benign nodular goiter. But the extention of thyroidectomy in the surgical management of benign nodular goiter still remains controversial. Seventytwo patients underwent thyroid surgery between April 2002- July2007 in Kızıltepe State Hospital Otorhinolaryngology Service. Of the patients 63 were women (%87.5, 9 were man (%12.5. The range of age was between 15-62 years and mean age was 36,5. Thirtynine patients had unilateral total lobectomy+ istmusectomy (%54.2, 11 patients had unilateral lobectomy+ isthmusectomy+contralateral subtotal lobectomy (Dunhill Procedure (%15.3, 20 patients had nearly total thyroidectomy (%27.8, 2 patients had total thyroidectomy (% 2.7. Three patients had seroma (%4.1, 2 patients had hemorrhage requiring operative hemostasis (%2.7, 1 patient had suture reaction(%1.3. Patients have not had permanent or temporary nervus laryngeus recurrens injury, hypoparathyroidism and infection.As a result more extent surgical resections must be preferred by the surgeon for the treatment of benign nodular goiter. The preferable surgical treatment of solitary nodules is lobectomy+isthmusectomy. The multinodular goiter must be treated with unilateral lobectomy+ isthmusectomy+contralateral subtotal lobectomy (Dunhill procedure when the remnant thyroid tissue is normal; otherwise nearly total or total thyroidectomy is preferable.

  6. Subjective visual vertical after treatment of benign paroxysmal positional vertigo

    Directory of Open Access Journals (Sweden)

    Maristela Mian Ferreira

    Full Text Available Abstract Introduction: Otolith function can be studied by testing the subjective visual vertical, because the tilt of the vertical line beyond the normal range is a sign of vestibular dysfunction. Benign paroxysmal positional vertigo is a disorder of one or more labyrinthine semicircular canals caused by fractions of otoliths derived from the utricular macula. Objective: To compare the subjective visual vertical with the bucket test before and immediately after the particle repositioning maneuver in patients with benign paroxysmal positional vertigo. Methods: We evaluated 20 patients. The estimated position where a fluorescent line within a bucket reached the vertical position was measured before and immediately after the particle repositioning maneuver. Data were tabulated and statistically analyzed. Results: Before repositioning maneuver, 9 patients (45.0% had absolute values of the subjective visual vertical above the reference standard and 2 (10.0% after the maneuver; the mean of the absolute values of the vertical deviation was significantly lower after the intervention (p < 0.001. Conclusion: There is a reduction of the deviations of the subjective visual vertical, evaluated by the bucket test, immediately after the particle repositioning maneuver in patients with benign paroxysmal positional vertigo.

    Benign esophageal lesions occur in various diseases. Barium studies are useful for the evaluation of mucosal surface lesions but provide little information about the extramucosal extent of disease. Computed tomography and magnetic resonance imaging, on the other hand, permit the assessment of wall thickness, mediastinal involvement, adjacent lymphadenopathy, and distant spread. In diseases such as fibrovascular polyps, duplication cysts, scleroderma, trauma, caustic esophagitis, hiatal hernia, esophageal diverticulum, achalasia, and paraesophageal varices, the findings of imaging studies are specific, obviating the need for further invasive diagnostic work-up. The advent of helical computed tomography and its volume data set allows the acquisition of multiplanar images, and magnetic resonance imaging is useful both for this and for tissue characterization. Thus, multiplanar cross-sectional imaging further extends the role of imaging modalities to the evaluation of benign esophageal lesions. Through an awareness of the multiplanar cross-sectional appearances of various benign esophageal lesions, the radiologist can play an important role in the detection, diagnosis, further diagnostic planning, and treatment of the diseases in which they occur.

  8. Visual search characteristics in mammography: malignant vs benign breast masses

    Mammography screening is the most widely utilized tool to screen for breast cancer. Radiologists read a mammogram using a two-pass strategy where the first pass is guided by salient features of the image (the so-called 'pop-out' elements), and the second pass is a systematic search. It is assumed that most breast masses that are reported by the radiologist are in fact detected during the first pass of this search strategy, and that the second pass is useful for the detection of microcalcification clusters. Furthermore, experiments in other visual domains have shown that observers are attracted faster to incongruous elements in a display than to normal (i.e., more expected) elements. In this sense, it can be argued that benign findings constitute more expected findings, because they encompass a large percentage of all abnormalities found on a mammogram. In this experiment we sought to determine whether the search for malignant masses was indeed faster than the search for benign masses. We also aimed to determine whether the observers' overall visual search behavior was different between benign and malignant cases, not only in terms of how long it took the observers to hit the location of the lesion, but also how long the observers took analyzing the case, how different the distribution of false positive responses were between the two types of cases, etc.

    Full Text Available We provide systematic evidence for the range and importance of hedonic reversals as a major source of pleasure, and incorporate these findings into the theory of benign masochism. Twenty-nine different initially aversive activities are shown to produce pleasure (hedonic reversals in substantial numbers of individuals from both college student and Mechanical Turk samples. Hedonic reversals group, by factor analysis, into sadness, oral irritation, fear, physical activity/exhaustion, pain, strong alcohol-related tastes, bitter tastes, and disgust. Liking for sad experiences (music, novels, movies, paintings forms a coherent entity, and is related to enjoyment of crying in response to sad movies. For fear and oral irritation, individuals also enjoy the body's defensive reactions. Enjoyment of sadness is higher in females across domains. We explain these findings in terms of benign masochism, enjoyment of negative bodily reactions and feelings in the context of feeling safe, or pleasure at ``mind over body''. In accordance with benign masochism, for many people, the favored level of initially negative experiences is just below the level that cannot be tolerated.

    Full Text Available Multiple sclerosis (MS, an inflammatory autoimmune disease, affects almost 1% of world’s population in which myelin sheaths of neurons are targeted by immune cells. Association of different factors and diseases with MS provides new insights into possible pathogenesis and treatment for this disease. In this regard, we investigated the association of benign tumors with MS disease by studying total Isfehan multiple sclerosis (TIMS records for MS patients registered in Isfahan Multiple Sclerosis Society (IMSS who had developed any kind of benign tumors whether before MS diagnosis or after it. This study was performed in Isfahan province, third large province of Iran, with 4,815,863 populations located 1590 meters above sea level between latitudes 30 and 34 degrees north of the equator, and longitude 49-55 east. Among 4950 registered patients, 28 patients were discovered to have three types of benign tumors; pituitary adenoma in 22, meningioma in 5 and lipoma in 1 patient. The incidence rate of developing pituitary adenoma and meningioma were higher than in general population (OR 95%CI: 1.110; range: 0.731-1.685 and 1.035; range: 0.431-2.487 respectively but these findings were not statistically significant (p= 0.624 for pituitary adenoma and p= 0.939 for meningioma. But the incidence rate for lipoma was lower among MS patients (OR 95%CI: 0.020; range: 0.003-0.143 which was statistically significant (p <0.001.

    Radioiodine therapy of benign and malignant thyroid diseases is a well-established procedure in Nuclear Medicine. However, the therapeutic use of radioisotopes in other diseases is relatively unknown among our refering physicians. The therapeutic effects of intraarticular (rheumatoid arthritis) and intracavitary (pleural and peritoneal carcinosis) applications yields good results. The radiophosphorus therapy in polycythemia vera rubra has always to be considered as an alternative to chemotherapy. The use of analgetics may be reduced by pain therapy of bone metastasis by injection of bone-seeking beta emitters like Rh-186 HEDP. Other procedures like therapeutic application of meta-iodo-benzylguanidine in neuroblastoma and malignant pheochromocytoma resulted in at least remissions of the disease. Radioimmunotherapy needs further evaluation before it can be recommended as a routine procedure. (orig.) [de

    Diffusion-weighted imaging (DWI) has increasingly gained in importance over the last 10 years especially in cancer imaging for differentiation of malignant and benign lesions. Through development of fast magnetic resonance imaging (MRI) sequences DWI is not only applicable in neuroradiology but also in abdominal imaging. As a diagnostic tool of the pancreas DWI enables a differentiation between normal tissue, cancer and chronic pancreatitis. The ADC values (apparent diffusion coefficient, the so-called effective diffusion coefficient) reported in the literature for healthy pancreatic tissue are in the range from 1.49 to 1.9 x 10{sup -3} mm{sup 2}/s, for pancreatic cancer in the range from 1.24 to 1.46 x 10{sup -3} mm{sup 2}/s and for autoimmune pancreatitis an average ADC value of 1.012 x 10{sup -3} mm{sup 2}/s. There are controversial data in the literature concerning the differentiation between chronic pancreatitis and pancreatic cancer. Using DWI-derived IVIM (intravoxel incoherent motion) the parameter f (perfusion fraction) seems to be advantageous but it is important to use several b values. In the literature the mean f value in chronic pancreatitis is around 16%, in pancreatic cancer 8% and in healthy pancreatic tissue around 25%. So far, DWI has not been helpful for differentiating cystic lesions of the pancreas. There are many references with other tumor entities and in animal models which indicate that there is a possible benefit of DWI in monitoring therapy of pancreatic cancer but so far no original work has been published.

    The total reflection X-ray fluorescence method was applied to study the trace element concentrations in human breast malignant and breast benign neoplasm tissues taken from the women who were patients of Holycross Cancer Centre in Kielce (Poland). These investigations were mainly focused on the development of new possibilities of cancer diagnosis and therapy monitoring. This systematic comparative study was based on relatively large ({approx} 100) population studied, namely 26 samples of breast malignant and 68 samples of breast benign neoplasm tissues. The concentrations, being in the range from a few ppb to 0.1%, were determined for thirteen elements (from P to Pb). The results were carefully analysed to investigate the concentration distribution of trace elements in the studied samples. The measurements of concentration of trace elements by total reflection X-ray fluorescence were limited, however, by the detection limit of the method. It was observed that for more than 50% of elements determined, the concentrations were not measured in all samples. These incomplete measurements were treated within the statistical concept called left-random censoring and for the estimation of the mean value and median of censored concentration distributions, the Kaplan-Meier estimator was used. For comparison of concentrations in two populations, the log-rank test was applied, which allows to compare the censored total reflection X-ray fluorescence data. Found statistically significant differences are discussed in more details. It is noted that described data analysis procedures should be the standard tool to analyze the censored concentrations of trace elements analysed by X-ray fluorescence methods.

    Full Text Available Abstract Background Alexithymia is a disturbance associated with psychosomatic disorders, pain syndromes, and a variety of psychiatric disorders. The Affect School (AS based on Tomkins Affect Theory is a therapy focusing on innate affects and their physiological expressions, feelings, emotions and scripts. In this pilot study we tried the AS-intervention method in patients with chronic benign pain. Methods The AS-intervention, with 8 weekly group sessions and 10 individual sessions, was offered to 59 patients with chronic non-malignant pain at a pain rehabilitation clinic in Sweden 2004-2005. Pre and post intervention assessments were done with the Hospital Anxiety and Depression scale (HAD, the Toronto Alexithymia Scale-20 (TAS-20, the Visual Analogue Scale for pain assessment (VAS-pain, the European Quality of Life health barometer (EQoL and the Stress and Crisis Inventory-93 (SCI-93. After the group sessions we used Bergdahl's Questionnaire for assessing changes in interpersonal relations, general well-being and evaluation of AS. Results The AS intervention was completed by 54 out of 59 (92% patients. Significant reductions in total TAS-20 post-test scores (p = 0.0006 as well as TAS-20 DIF and DDF factors (Difficulties Identifying Feelings, and Difficulties Describing Feelings were seen (p = 0.0001, and p = 0.0008 while the EOT factor (Externally Oriented Thinking did not change.

    The intention of the present thesis was the evaluation of a potential parathyroid dysfunction under treatment with radioactive iodine of benign thyroid diseases. It was to be examined whether a change in the parathyroid function would arise within the first week on treatment. So far there are some minor studies existing describing significant changes in the parathyroid hormone serum level within the first months after radioactive iodine therapy of benign and malignant thyroid diseases. Moreover, it is a fact that external beam-radiotherapy can induce neoplasia and that the risk for the subsequent development of primary hyperparathyroidism doubles or triples after external beam-radiotherapy of the head and neck. Up to now, however, an increased incidence for primary hyperparathyroidism following treatment with radioactive iodine ( 131 I) could not be proved. At the department of nuclear medicine of the university hospital Giessen-Marburg GmbH, location Marburg, a prospective cohort study was executed on radioactive iodine therapy of benign thyroid diseases with 105 probands (75 women / 30 men, mean age 60.62 ± 14.3 years). According to their thyroid diseases these 105 probands were classified into following subgroups: thyroid adenoma with 23 patients, multifocal thyroid autonomy with 8 patients, disseminated thyroid autonomy with 37 patients as well as the subgroup Graves' hyperthyroidism (without Graves' ophtalmopathy) and accordingly Graves' disease (with Graves' ophtalmopathy) with 37 patients. The serum level of the intact parathyroid hormone was determined directly before starting the radioactive iodine therapy on the admission day and on day 1, 3 and 5 of the radioactive iodine therapy as well as at the ambulant follow-up examination one month after the start of the therapy. In case of 99 of 105 probands the serum level of parathyroid hormone declined on treatment with 131 I with its nadir on day 3 of therapy (decline by 15.71 ng/l or 27

    Full Text Available Benign liver tumors are very rare in children. Most focal nodular hyperplasia (FNH remain sporadic, but predisposing factors exist, as follows: long-term cancer survivor (with an increasing incidence, portal deprivation in congenital or surgical portosystemic shunt. The aspect is atypical on imaging in two-thirds of cases. Biopsy of the tumor and the nontumoral liver is then required. Surgical resection will be discussed in the case of large tumors with or without symptoms. In the case of associated vascular disorder with portal deprivation, restoration of the portal flow will be discussed in the hope of seeing the involution of FNH. HepatoCellular Adenoma (HCA is frequently associated with predisposing factors such as GSD type I and III, Fanconi anemia especially if androgen therapy is administered, CPSS, and SPSS. Adenomatosis has been reported in germline mutation of HNF1-α. Management will depend on the presence of a predisposing factor and may include metabolic control, androgen therapy withdrawn, or closure of the shunt when appropriate. Surgery is usually performed on large lesions. In the case of adenomatosis or multiple lesions, surgery will be adapted. Close followup is required in all cases.

    Full Text Available Benign paroxysmal positional vertigo (BPPV is the most common cause of vertigo of peripheral origin. The lateral semicircular canal (LSCC follows the posterior semicircular canal (PSCC as the site of pathology in the majority of patients. Therapy, aiming at relocating particles causing aberrant LSCC stimulation has been applied by forced prolonged positioning, barbecue, and particle repositioning maneuvers. Results of the different techniques are variable. This systematic review/meta-analysis aimed to find out which therapy technique yields higher cure rates. MedLine database provided at National Library of Medicine was searched for randomized controlled trials comparing results of different therapeutic techniques for patients with LSCC BPPV. For studies included in qualitative analysis/synthesis, the following were collected independently by the author: number of participants, count of patients with geotropic and apogeotropic LSCC in each treatment group, and resolution of vertigo/nystagmus assessed by symptomatic improvement and negative supine roll test 1–24 hours following intervention considering the type of LSCC BPPV (geotropic/apogeotropic. Level Ia evidence (systematic review of RCTs shows superiority of Gufoni maneuver over sham for both geotropic and apogeotropic LSCC BPPV.

    Full Text Available Background and ObjectiveBalloon dilatation of stricture is one of the new treatment methods for patients with Gastric Outlet Obstruction (GOO. Prevalence and underlying etiologies of GOO in various populations are different. The goal of the present study was to determine the effectiveness of endoscopic balloon dilatation and factors that could affect method advantage among patients with benign etiology for GOO. Methods Forty-five patients with symptoms of benign GOO were randomly selected. The mean age of patients was 43.7±18.1 years and 86.7% of them were men. Gastric outlet was delineated using double channel videoendoscopy. The severity of gastric pain was measured by VAS test immediately before and one month after balloon dilatation. Patients were followed after procedure weekly (for the first month and then monthly. Balloon dilatation was repeated for 27% patients during the follow up period.ResultsPatients were followed for 9.9±5.8 months. Furthermore, 71.1% were H. pylori positive. Positive response percent to endoscopic balloon dilatation was 80% and eight patients were took under surgical resection. Weight loss was seen frequently in the non-respondent group. The pain severity was significantly reduced in respondent subjects. No meaningful correlations were found between the response to balloon dilatation and positive H. pylori and cigarette smoking.ConclusionEndoscopic balloon dilatation is a safe and effective method for treating most of patients with benign gastric outlet obstruction and has favorable long-term outcome.

    The objective was to characterize imaging findings of benign notochordal cell tumors (BNCTs). Clinical and imaging data for 9 benign notochordal cell tumors in 7 patients were reviewed retrospectively. Conventional radiographs (n = 9), bone scintigrams (n = 2), computed tomographic images (n = 7), and magnetic resonance images (n = 8) were reviewed. Eight of the 9 lesions were stained with hematoxylin-eosin and microscopically examined. There were 3 male and 4 female patients with an age range of 22 to 55 years (average age, 44 years). Two patients had two lesions at different sites. The lesions involved the cervical spine in 4 patients, the lumbar spine in 2, the sacrum in 2, and the coccyx in 1. The most common symptom was mild pain. The lesions of 2 patients were found incidentally during imaging studies for unrelated conditions. Five patients underwent surgical procedures. One patient died of surgical complications. All other patients have been well without recurrent or progressive disease for 13 to 84 months. Radiographs usually did not reveal significant abnormality. Five lesions exhibited subtle sclerosis and 1 showed intense sclerosis. Technetium bone scan did not reveal any abnormal uptake. Computed tomography images had increased density within the vertebral bodies. The lesions had a homogeneous low signal intensity on T1-weighted magnetic resonance images and a high intensity on T2-weighted images without soft-tissue mass. Microscopically, lesions contained sheets of adipocyte-like vacuolated chordoid cells without a myxoid matrix. Benign notochordal cell tumors may be found during routine clinical examinations and do not require surgical management unless they show extraosseous disease. These tumors should be recognized by radiologists, pathologists, and orthopedic surgeons to prevent operations, which usually are extensive. (orig.)

    Full Text Available Breast cancer is the primary and most common disease found in women which causes second highest rate of death after lung cancer. The digital mammogram is the X-ray of breast captured for the analysis, interpretation and diagnosis. According to Breast Imaging Reporting and Data System (BIRADS benign and malignant can be differentiated using its shape, size and density, which is how radiologist visualize the mammograms. According to BIRADS mass shape characteristics, benign masses tend to have round, oval, lobular in shape and malignant masses are lobular or irregular in shape. Measuring regular and irregular shapes mathematically is found to be a difficult task, since there is no single measure to differentiate various shapes. In this paper, the malignant and benign masses present in mammogram are classified using Hue, Saturation and Value (HSV weight function based statistical measures. The weight function is robust against noise and captures the degree of gray content of the pixel. The statistical measures use gray weight value instead of gray pixel value to effectively discriminate masses. The 233 mammograms from the Digital Database for Screening Mammography (DDSM benchmark dataset have been used. The PASW data mining modeler has been used for constructing Neural Network for identifying importance of statistical measures. Based on the obtained important statistical measure, the C5.0 tree has been constructed with 60-40 data split. The experimental results are found to be encouraging. Also, the results will agree to the standard specified by the American College of Radiology-BIRADS Systems.

    The transformation of a benign fibroadenoma into a phyllodes tumor is uncommon and unpredictable. We report the case of a 40-year-old woman with a core biopsy proven fibroadenoma that underwent transformation into a malignant phyllodes tumor after 3 years of size stability. We present ultrasound and magnetic resonance images, as well as pathology slides from core biopsy and surgical excision, to illustrate this transformation. It has been suggested that phyllodes tumors may be misdiagnosed as fibroadenomas by core biopsy. However, in this case, pathology supports correct initial diagnosis of fibroadenoma and demonstrates a portion of the original fibroadenoma along the periphery of the malignant phyllodes tumor

    Full Text Available Zoon’s balanitis or balanitis circumscripta plasmacellularis is a chronic disease of unknown origin.This condition usually manifests in middle-aged or elderly uncircumcised men. Although of unknown etiology, different factors have been reported to be involved in its genesis (local infections, poor hygiene, heat, friction, and constant rubbing. It is generally considered to be a benign condition, and its association with malignancies has been rarely reported. We report the case of an uncircumcised man, who developed clinically and histopathologically evident squamous cell carcinoma of the penis in an area affected by Zoon’s balanitis.

    A seventy two year old man presented to the Emergency Department with clinical features of colonic obstruction. Subsequent radiological investigations confirmed this impression and revealed the aetiology to be compression of the sigmoid colon against the sacrum by a massively distended urinary bladder. Chronic urinary retention due to benign prostatic hypertrophy is an extremely unusual cause of large bowel obstruction. Little in this patient\\'s clinical findings suggested this aetiology. We reviewed the literature in this area and highlight the benefits of CT scanning over contrast studies.

    The American Academy of Otolaryngology-Head and Neck Surgery Foundation has published a supplement to this issue of Otolaryngology-Head and Neck Surgery featuring the "Clinical Practice Guideline: Benign Paroxysmal Positional Vertigo (Update)." To assist in implementing the guideline recommendations, this article summarizes the rationale, purpose, and key action statements. The 14 recommendations developed emphasize diagnostic accuracy and efficiency, reducing the inappropriate use of vestibular suppressant medications, decreasing the inappropriate use of ancillary testing, and increasing the appropriate therapeutic repositioning maneuvers. An updated guideline is needed due to new clinical trials, new systematic reviews, and the lack of consumer participation in the initial guideline development group.

    Full Text Available Benign paroxysmal positional vertigo (BPPV is the most common disorder of the peripheral vestibular system, characterized by intense, positional provoked vertigo. BPPV is thought to occur due to canalithiasis of the posterior semicircular canal. Recently, a new entity of BPPV, known as horizontal canal (HC-BPPV, has been recognized. Although only 3 to 8% of BPPV is due to horizontal canal involvement, HC-BPPV is not rare. We present a case of a naval fighter pilot who had an incident of HC-BPPV on the ground. The pilot aeromedical evaluation and considerations are discussed.

    Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo characterized by brief episodes provoked by head movements. The first attack of BPPV usually occurs in bed or upon getting up. Because it often begins abruptly, it can be alarming and lead to emergency department evaluation. The episodes of spinning often last 10 to 20 seconds, but may occasionally last as long as 1 minute. There are several forms of BPPV. In nearly all cases, highly effective treatment can be offered to patients. This article reviews the current state of our understanding of this condition and its management.

    We investigated the MRI appearance of the optic nerve and its cerebrospinal-fluid-containing sheath in 17 patients with benign intracranial hypertension (BIH) and 15 normal controls. Using phased-array local coils, 3-mm coronal T2-weighted fat-suppressed fast spin-echo images were obtained with an in-plane resolution of < 0.39 mm. The optic nerve and its sheath were clearly differentiated. An enlarged, elongated subarachnoid space around the optic nerve was demonstrated in patients with BIH. High-resolution MRI of the optic nerve offers additional information which may be of value for diagnosis and in planning and monitoring treatment. (orig.). With 5 figs

    Full Text Available Benign paroxysmal positional vertigo (BPPV is the most frequent episodic vestibular disorder. It is due to otolith rests that are free into the canals or attached to the cupulas. Well over 90% of patients can be successfully treated with manoeuvres that move the particles back to the utriculus. Among the great variety of procedures that have been described, the manoeuvres that are supported by evidenced-based studies or extensive series are commented in this review. Some topics regarding BPPV treatment, such as controlling the accuracy of the procedures or the utility of post-manoeuvre restrictions are also discussed.

    Case report. To present a rare case of a notochordal cell tumor. We report on a 27-year-old female patient with pain at the lower back and muscle cramps in the area of the right hip. Image studies demonstrated a cystic lesion of the coccyx. As clinical symptoms became chronic and were resistant to conservative treatment, a resection of the coccyx was performed. Histology revealed an intraosseous benign notochordal cell tumor. This tumor represents a recently described notochordal cell proliferation biologically distinct from chordomas. Overdiagnosis of these notochordal cell proliferations as chordomas may occur if clinicians and pathologists are unfamiliar with the spectrum of notochordal proliferations.

    The authors diagnosed a 33 years old female as benign lymphoepithelial lesion after undergoing clinical, radiological and histopathological examinations and the characteristics were as follows : 1. Clinically, the patient complained of painless bilateral swelling of the parotid glands and dryness of the palate. Rheumatoid facor was detected in her serum. 2. Sialograms showed punctuate or globular collections of contrast media distributed evenly throughout the parotid gland s in so-called 'cherry blossom' or 'fearless fruit-laden tree' appearance. 3. A salivary gland scan showed no uptake of radioisotopes by the parotid glands. 4. At T1-weighted imaging of PNS MRI, the lesions had the same signal intensity as the rest of the gland. At T2-weighted imaging, the lesion could be seen as high signal intensity 1.3 cm and 2.1 cm in diameter in the left and the right parotid gland respectively. 5. Ultrasonogram showed sonolucent lesions 20 X 15 mm and 17 X 14 mm in size in the lower part of the left parotid gland an d another 18 X 11 mm in size in the lower part of the parotid gland AS well as many other small sonolucent lesions. 6. Histopathologically, lymphocytic infiltration replacing the normal acini and lymphoid follicles containing germinal centers could be seen. Epimyoepithelial islands were scattered throughout the lesion and benign lymphoepithelial cysts were also observed.

    To assess the radiographic and clinicopathologic features of synovial sarcoma of the nerve that were clinically or radiologically interpreted as benign peripheral nerve sheath tumor. Five patients with synovial sarcoma arising from the peripheral nerve and interpreted clinically and radiologically as peripheral nerve sheath tumors were identified. Clinicopathologic and imaging features were evaluated. There were three females and two males, ranging in age from 28 to 50 (mean 35.8) years. Most patients (4/5) complained of a mass, discomfort or pain. MR images demonstrated a heterogeneous, enhancing, soft tissue mass contiguous with the neurovascular bundle. On histologic examination, most tumors were monophasic synovial sarcoma (4/5). At the time of surgery, all tumors were noted to arise along or within a peripheral nerve. All patients were alive with no evidence of disease with median follow-up of 44 (range 32-237) months. For comparison, approximately 775 benign peripheral nerve sheath tumors of the extremities were identified during the same time period. Primary synovial sarcoma of the nerve can mimic peripheral nerve sheath tumors clinically and on imaging and should be included in the differential diagnosis for tumors arising from peripheral nerves.

    Surgical management of gastric outlet obstruction may associate with significant morbidity and mortality. Few studies have documented surgical outcomes in elderly patients. The aim of this study was to review recent operative results of benign gastric outlet obstruction in elderly patients compared with younger patients. Forty- seven consecutive patients from January 2000 through September 2008 were included. Preoperative, intraoperative data and early postoperative complications were analyzed. Fifteen operations were performed in elderly patients and 32 in younger patients. More patients in the elderly group were assigned as ASA class 3 (p=0.037), but Charlson comorbidity index was similar. Procedure types included Finney or Jaboulay pyloroplasty (n=26), antrectomy (n=13) and gastrojejunostomy (n=8). The mean postoperative hospital stay was 14.9 days. A modest correlation between the length of stay and the patient's age (p=0.044; r=0.294) was observed. There were two in hospital mortalities and four patients had complications. Surgery for benign gastric outlet obstruction is safe in the elderly population and is not associated with any increase in morbidity or mortality.

    The overall program objective is to develop and evaluate environmental benign agents or products that are effective in the prevention, inhibition, and mitigation of microbially influenced corrosion (MIC) in the internal surfaces of metallic natural gas pipelines. The goal is one or more environmental benign, a.k.a. ''green'' products that can be applied to maintain the structure and dependability of the natural gas infrastructure. The technical approach for this quarter were monitoring the development of Desulfovibrio species biofilm using the continuous flow cell system, evaluation of pepper compounds by microtiter plate assay for mitigating and inhibiting biofilm formation, and testing the effective concentrations to verify the extent of corrosion on metal coupons. Biofilm formation of Desulfovibrio vulgaris and D. desulfuricans was monitored and documented over a 7-day period. The use of a continuous flow cell system proved to be efficient and non-destructive in studying biofilm growth. Live/Dead BacLight was an efficient stain to determine cell viability. The extracts showed 9-25% biofilm formation inhibition against the two organisms, and 18-19% activity in detaching the already formed biofilm. Preliminary data were obtained on the extent of corrosion of metal coupons when treated with pepper extracts as against the untreated ones. Confirmatory tests are underway. A presentation was prepared and give at the US DOE NETL meeting on gas and petroleum infrastructure. The presentation is include as an addition to this report.

    The overall program objective is to develop and evaluate environmental benign agents or products that are effective in the prevention, inhibition, and mitigation of microbially influenced corrosion (MIC) in the internal surfaces of metallic natural gas pipelines. The goal is one or more environmental benign, a.k.a. ''green'' products that can be applied to maintain the structure and dependability of the natural gas infrastructure. Capsicum sp. extracts and pure compounds were screened for their antimicrobial activity against MIC causing bacteria. Studies on the ability of these compounds to dissociate biofilm from the substratum were conducted using microtiter plate assays. Tests using laboratory scale pipeline simulators continued. Preliminary results showed that the natural extracts possess strong antimicrobial activity being comparable to or even better than the pure compounds tested against strains of sulfate reducers. Their minimum inhibitory concentrations had been determined. It was also found that they possess bactericidal properties at minimal concentrations. Biofilm dissociation activity as assessed by microtiter plate assays demonstrated varying degrees of differences between the treated and untreated group with the superior performance of the extracts over pure compounds. Such is an indication of the possible benefits that could be obtained from these natural products. Confirmatory experiments are underway.

    In summary, the lecture presents today's state of nuclear medical diganostics in benign bone disease, the radiopharmaceuticals, and the methods used. Besides the 99 m-Tc-labeled diphosphonates a couple of additional radioactive labeled substances play an important part in bone scintigraphic imaging especially in scanning inflammatory bone disease and the bone marrow. There are several substances available to label leucocytes and human immunoglobulins. Concerning the methods the performance of the 3-phase bone scanning and the application of SPECT becomes increasingly important. In detail discussed are among other methods the inflammation-scanning in osteomyelitis, the scintigraphic imaging in benign bone tumors and tumor like lesions, in circulation disorders of the bone with necroses and hyperperfusion (reflex sympathetic dystrophy, transient hip osteoporosis), and in bone lesions following trauma or stress, for example also in battered child syndrome. The indication to the different imaging procedures as X-ray, computed tomography, nuclear magnetic resonance, and scintigraphic imaging are discussed, whereby the scintiscanning urges its place, mainly due to good specifity, in documenting the different functional states of the bone such as inflammation, perfusion, necrosis, tumor and/or bone marrow infiltration.

    Full Text Available Benign breast lesions (BBL includes a wide variety of histologic entities, which have been broadly classified into non-proliferative lesions, proliferative lesions without atypia, and hyperplasia with atypia. With the increased use of mammography, more benign lesions are being detected, and in order to estimate the risk of breast cancer for specific histologic categories is of great importance to guide clinical management. Women with proliferative lesions without atypia are at slightly increased risk of subsequent breast cancer, whereas women with proliferative lesions with atypia have a higher risk. The risk is 1.5- 2-fold in women with proliferative lesions without atypia, 4-5-fold in women with proliferative lesions with atypia, and 8-10 fold in women with ductal carcinoma in situ. Age at diagnosis of BBL, menopausal status, family history of breast cancer in a first-degree relative, and time since BBL diagnosis on risk of breast cancer are important for risk evaluation.

    Full Text Available There are various types of benign skin tumors in association with the complex nature of the skin. A minor part of them may be associated with visceral malignancies. This review focuses on the benign skin tumors that are described to have well-known associations with systemic malignancies or those with controversial associations. These tumors and the associated conditions are as follows: seborrheic keratosis/ Leser-Trélat sign, lentigo simplex/Peutz Jeghers and Carney syndrome, sebaceous tumors/ Muir-Torre syndrome, fibrofolliculoma- trichodiskoma/ Birt-Hogg-Dubé syndrome, trichoepitheliomacylindroma- spiradenoma/ Brooke-Spiegler syndrome, leiomyoma/multiple cutaneous and uterin leiomyomatosis syndrome, glomeruloid hemangioma/ POEMS syndrome, venous malformation/ Maffucci syndrome, mucosal neuroma/ multiple endocrine neoplasia type 2B, juvenile xanthogranuloma/ juvenile chronic myeloid leukemia. It is important to know the skin tumors related with visceral malignancies in part of a syndrome or in association with a sign as this may yield an earlier recognition of these malignancies.

    Full Text Available Benign multicystic mesothelioma (BMCM is a rare tumor of the abdomen-peritoneum of unknown etiology. This benign tumor was initially described by Plaut in 1928 when he observed loose cysts in the pelvis during a surgery for a uterine leiomyoma.2 The mesothelial origin was later confirmed by electron micro-scopy by Mennemeyer and Smith in 1979.3 To date, there are approximately 140 cases of BMCM reported in the literature.4 This disease primarily occurs in pre-menopausal women and is associated with a history of pelvic inflammatory disease, prior abdominal surgery, and endometriosis.4,5 The pathogenesis of this disease remains controversial, with possible etiologies including a neoplastic versus a reactive process.5 In the literature, a few case reports discuss a possible genetic or familial association with BMCM.6 Specifically, one report describes a man with familial Mediterranean fever who developed BMCM. Although familial Mediter-ranean fever is associated with malignant mesothelioma, he had only BMCM, and did not suffer from malignant mesothelioma.6 A genetic evaluation and chromosomal analysis were not able to identify a specific genetic cause of the family’s pattern of disease. This case report describes two female siblings diagnosed with BMCM. In addition, a third sister also had findings consistent with BMCM, however, the discrete histological diagnosis was never confirmed.

    We studied the clinical characteristics, nystagmographic findings, and treatment outcome of a group of patients with benign paroxysmal positional vertigo (BPPV) secondary to mild head trauma and compared them with a group of patients with idiopathic BPPV. The medical records of 33 patients with BPPV associated with mild head trauma were reviewed. Data of a complete otolaryngological, audiological, neurotologic, and imaging evaluation were available for all patients. Three hundred and twenty patients with idiopathic BPPV were used as a control group. The patients with BPPV secondary to mild head trauma presented the following features, in which they differed from the patients with idiopathic BPPV: (1) lower mean age, with more intense symptoms; (2) increased rate of horizontal and anterior semicircular canal involvement and frequent multiple canal and bilateral involvement; (3) greater incidence of canal paresis and presence of spontaneous nystagmus; (4) poorer treatment results, attributed mainly to coexisting canal paresis in many patients, and higher rate of recurrence. Benign paroxysmal positional vertigo associated with mild head trauma differs from idiopathic BPPV in terms of several epidemiological and clinical features; it responds less effectively to treatment and is prone to recurrence. © The Author(s) 2016.

    Otolith function can be studied by testing the subjective visual vertical, because the tilt of the vertical line beyond the normal range is a sign of vestibular dysfunction. Benign paroxysmal positional vertigo is a disorder of one or more labyrinthine semicircular canals caused by fractions of otoliths derived from the utricular macula. To compare the subjective visual vertical with the bucket test before and immediately after the particle repositioning maneuver in patients with benign paroxysmal positional vertigo. We evaluated 20 patients. The estimated position where a fluorescent line within a bucket reached the vertical position was measured before and immediately after the particle repositioning maneuver. Data were tabulated and statistically analyzed. Before repositioning maneuver, 9 patients (45.0%) had absolute values of the subjective visual vertical above the reference standard and 2 (10.0%) after the maneuver; the mean of the absolute values of the vertical deviation was significantly lower after the intervention (pparoxysmal positional vertigo.

    The purpose of this study is to evaluate the characteristics of parotid gland tumors to help in the differentiation between benign and malignant lesions. The CT findings of 22 patients with surgically proven parotid gland tumors were reviewed. Analysis was focused on the density and margin characteristics of the tumors, and the relationship between the tumor and surrounding structures. Those tumors were pleomorphic adenoma (n = 8), Warthin's tumor (n = 5), basal cell adenoma (n = 1), lipoma (n = 1), dermoid cyst (n = 1), adenoid cystic carcinoma (n = 2), mucoepidermoid carcinoma (n 1), epidermoid carcinoma (n = 1), and carcinoma in pleomorphic adenoma (n 1). Most of benign and malignant tumors were heterogeneous in density on contrast enhanced CT scans. In 5 of 6 malignant cases, the tumors had irregular or ill-defined margin and a tendancy to involve or cross the superficial layer of deep cervical fascia with obliteration of subcutaneous fat. Two malignant tumors invaded surrounding structures. Although the heterogeneous density of tumor is not a specific finding for malignancy at CT, following findings, such as, irregular or blurred margin of the lesion, the involvement of fascial plane, and the infiltration of surrounding structures may suggest the possibility of malignant parotid tumor.

    In reproductive women, various physiologic conditions can cause morphologic changes of the ovary, resembling pathologic conditions. Benign ovarian diseases can also simulate malignancies. Magnetic resonance imaging (MRI) can play an important role in establishing accurate diagnosis. Functional cysts should not be confused with cystic neoplasms. Corpus luteum cysts typically have a thick wall and are occasionally hemorrhagic. Multicystic lesions that may mimic cystic neoplasms include hyperreactio luteinalis, ovarian hyperstimulation syndrome, and polycystic ovary syndrome. Recognition of clinical settings can help establish diagnosis. In endometrial cysts, MRI usually provides specific diagnosis; however, decidual change during pregnancy should not be confused with secondary neoplasm. Peritoneal inclusion cysts can be distinguished from cystic neoplasms by recognition of their characteristic configurations. Ovarian torsion and massive ovarian edema may mimic solid malignant tumors. Recognition of normal follicles and anatomic structures is useful in diagnosing these conditions. In pelvic inflammatory diseases, transfascial spread of the lesion should not be confused with invasive malignant tumors. Radiologic identification of abscess formation can be a diagnostic clue. Many benign tumors, including teratoma, Brenner tumor, and sex-cord stromal tumor, frequently show characteristic MRI features. Knowledge of MRI features of these conditions is essential in establishing accurate diagnosis and determining appropriate treatment. (orig.)

    In 2014, the Korean Urological Association organized the Benign Prostatic Hyperplasia Guideline Developing Committee composed of experts in the field of benign prostatic hyperplasia (BPH) with the participation of the Korean Academy of Family Medicine and the Korean Continence Society to develop a Korean clinical practice guideline for BPH. The purpose of this clinical practice guideline is to provide current and comprehensive recommendations for the evaluation and treatment of BPH. The committee developed the guideline mainly by adapting existing guidelines and partially by using the de novo method. A comprehensive literature review was carried out primarily from 2009 to 2013 by using medical search engines including data from Korea. Based on the published evidence, recommendations were synthesized, and the level of evidence of the recommendations was determined by using methods adapted from the 2011 Oxford Centre for Evidence-Based Medicine. Meta-analysis was done for one key question and four recommendations. A draft guideline was reviewed by expert peer reviewers and discussed at an expert consensus meeting until final agreement was achieved. This evidence-based guideline for BPH provides recommendations to primary practitioners and urologists for the diagnosis and treatment of BPH in men older than 40 years. PMID:26966724

    The sternocleidomastoid (SCM) partial thickness muscle flap is among the various methods described to correct parotidectomy defects, but its indications and limitations are not clearly demonstrated in several reports. This study was done to test the aesthetic outcome of this method, its indications and limitations. The technique was combined with a face lift incision to further improve the outcome. Patients and methods: At the National Cancer Institute, Cairo University, Egypt, 23 patients presenting with benign tumors underwent parotidectomy, 19 had superficial parotidectomy and four had total parotidectomy done. The superiorly based (SCM) muscle flap was used to correct the contour deformity. The aesthetic result was evaluated by assessing arid scoring the overall appearance of the scar, the degree of symmetry of the reconstructed parotid region and the site of the donor muscle to their contralateral normal sides. The overall aesthetic appearance was then calculated by the summation of the scores of the latter three parameters. Patients' satisfaction was assessed by patients' questionnaire. Result: The overall aesthetic appearance was good in 17 patients, and moderate in six patients. 16/23 patients had an overall deep satisfaction with the result. The residual hollowness of the parotid following reconstruction of the total parotidectomy defect and the poor quality of scars were the main reasons affecting the aesthetic outcome. Conclusion: Superficial parotidectomy through facelift incision with immediate reconstruction with superiorly based partial thickness SCM flap allows adequate resection of most benign parotid tumors with a satisfactory aesthetic outcome and minimal donor site morbidity

    Full Text Available Epilepsy is a neurological disorder characterized by abnormal electrical discharges in a group of brain cells. Benign childhood epilepsy, which affect children under the age of 12 years, has been reported to contribute to the cognitive impairment of these children, even in the absence of structural abnormalities. Functional connectivity models have been applied to provide a deeper understanding of the processes that control and regulate interictal activity of benign childhood epilepsy. These studies have shown regions of increased connectivity and activity, particularly at the epileptic zone, which is usually the central region around the sensorimotor cortex, and in the immediate regions surrounding the zone and reduced activity in distant regions, such as the frontal lobe and temporal regions. The present study was designed to identify the neural drivers involved in the initiation and propagation of epileptic activity and the causal relationships between brain regions with increased and decreased connectivity and functional activity. We used three different models to identify neural drivers and casual connectivity with dynamic causal modelling (DCM of EEG data. All models showed that the central region, the source of the epileptic activity, is the major driver of the brain network during interictal discharges. Other regions include the temporoparietal junction and temporal pole. The central region also had influence on the frontal and contralateral hemisphere, which might explain the cognitive deficits observed in these patients.

    To assess the frequency of malignancy in lesions characterized as benign [Breast Imaging-Reporting and Data System (BI-RADS) 2] on breast MRI. In this institutional review board-approved retrospective single-centre study, 1265 consecutive patients (mean age 50 ± 13 years), undergoing dynamic contrast-enhanced MRI (1.5 T) of the breast during a 6 year time period, were eligible. This study investigated the MRI characteristics and frequency of malignancy in 192 of these patients with breast lesions classified as BI-RADS 2. Examinations were read during clinical practice and classified according to the MRI BI-RADS lexicon. Based on the patient's and referring physician's preferences, lesions were either histopathologically verified or were subjected to both clinical and imaging follow-up of at least 2 years (range 2-9 years). Descriptive statistical metrics were calculated. According to the standard of reference, 0 of 192 (0%) lesions classified as BI-RADS 2 were malignant. Histopathology was available in 67 (34.9%) lesions and revealed benign findings exclusively. The remaining 125 (65.1%) lesions did not exhibit changes during the follow-up period and were, therefore, considered negative for malignancy. The frequency of malignancy in breast lesions classified as BI-RADS 2 is zero. As a consequence, breast biopsies are unnecessary in these cases. Copyright © 2014 The Royal College of Radiologists.

    Although the clinical symptoms of patients with benign parathyroid adenoma are usually nonspecific and benign, a malignant presentation of the benign disease may sometimes occur. Here, we report a case of a 58-year-old woman who presented with aggravated sacrum pain, general malaise, and polydipsia. Initial laboratory findings revealed hypercalcemia, normocytic anemia, and impaired renal function. Acute hyper-calcemic crisis manifested and primary hyperparathyroidism was diagnosed together wi...

    Benign prostatic hyperplasia (BPH) is the major cause of lower urinary tract symptoms in men aged 50 or older. Symptoms are not normally life threatening, but often drastically affect the quality of life. The number of men seeking treatment for BPH is expected to grow in the next few years as a result of the ageing male population. Estimates of annual pharmaceutical sales of BPH therapies range from $US 3 to 10 billion, yet this market is dominated by two drug classes. Current drugs are only effective in treating mild to moderate symptoms, yet despite this, no emerging contenders appear to be on the horizon. This is remarkable given the increasing number of patients with severe symptoms who are required to undergo invasive and unpleasant surgery. This review provides a brief background on prostate function and the pathophysiology of BPH, followed by a brief description of BPH epidemiology, the burden it places on society, and the current surgical and pharmaceutical therapies. The recent literature on emerging contenders to current therapies and novel drug targets is then reviewed, focusing on drug targets which are able to relax prostatic smooth muscle in a similar way to the α1-adrenoceptor antagonists, as this appears to be the most effective mechanism of action. Other mechanisms which may be of benefit are also discussed. It is concluded that recent basic research has revealed a number of novel drug targets such as muscarinic receptor or P2X-purinoceptor antagonists, which have the potential to produce more effective and safer drug treatments.

    To evaluate differential points of clustered microcalcification in malignant and benign lesions on histopathology and correlate with mammographic findings. Authors evaluated differential points of malignant and benign calcifications in histopathologically confirmed 24 cases. In two patients, mapping studies and paraffin block mammographic examinations were done to correlate calcification on mammography with histopathologic morphology. On histopathology, malignant calcifications were located in ductal lumen, while benign ones were usually located in ductal epithelium ({rho} < 0.05). However, associated three benign lesions of the 10 malignant lesions showed still benign calcifications adjacent to proven cancer. The typical malignant calcifications were the shape of lamination, while benign calcifications showed granular and salty on light microscope. In 2 mapping studies, malignant-looking calcifications within the area of predominant benign calcifications yielded atypical ductal hyperplasia. Mammographic pepper, granular, punctuate, salty and S-shaped calcifications were correlated with granular and salty calcification on light microscope. Mammographic linear, branching comma, tadpole and wormiform calcifications were correlated with histopathologic laminated calcification. Authors have recognized about characteristics of malignant Vs. benign clustered microcalcifications on histopathology. Authors concluded that if malignant-looking calcification such as linear, branching, comma, tadpole and wormiform are present in an are a of predominant benign calcifications, specimen radiographic correlation and mapping study will be necessary for better demonstration of the atypical ductal hyperplasia, hidden or associated breast cancer.

    Few studies have repeatedly evaluated quality of life and potentially relevant factors in patients with benign primary brain tumor. The purpose of this study was to explore the relationship between the experience of the symptom distress, functional status, depression, and quality of life prior to surgery (T(1)) and 1 month post-discharge (T(2)). This was a prospective cohort study including 58 patients with benign primary brain tumor in one teaching hospital in the Taipei area of Taiwan. The research instruments included the M.D. Anderson Symptom Inventory, the Functional Independence Measure scale, the Hospital Depression Scale, and the Functional Assessment of Cancer Therapy-Brain. Symptom distress (T(1): r = -0.90, p life. Multivariate analysis identified symptom distress (explained 80.2%, R (inc)(2) = 0.802, p = 0.001) and depression (explained 5.2%, R (inc)(2) = 0.052, p life prior to surgery (T(1)) after controlling for key demographic and medical variables. Furthermore, only symptom distress (explained 27.1%, R (inc)(2) = 0.271, p = 0.001) continued to have a significant independent influence on quality of life at 1 month after discharge (T(2)). The study highlights the potential importance of a patient's symptom distress on quality of life prior to and following surgery. Health professionals should inquire about symptom distress over time. Specific interventions for symptoms may improve the symptom impact on quality of life. Additional studies should evaluate symptom distress on longer-term quality of life of patients with benign brain tumor.

    Full Text Available Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Benign Paroxysmal Positional Vertigo (BPPV is one of the most frequent Neurotology disorders. Benign Paroxysmal Positional Vertigo is a vestibular disorder in which 17% -20% of patients complained of vertigo. In the general population the prevalence of BPPV is between 11 to 64 per 100,000 (prevalence 2.4%. Benign Paroxysmal Positional Vertigo is a disturbance in the inner ear with positional vertigo symptoms that occur repeatedly with the typical nystagmus paroxysmal. The disorders can be caused either by canalithiasis or cupulolithiasis and could in theory be about three semicircular canals, although superior canal (anterior is very rare. The most common is the form of the posterior canal, followed by a lateral. The diagnosis of BPPV can be enforced based on history and physical examination, including some tests such as Dix-Hallpike test, caloric test, and Supine Roll test. The diagnosis of BPPV is also classified according to the types of channels. Management of BPPV include non-pharmacological, pharmacological and operations. Treatment is often used non-pharmacological includes several maneuvers such as Epley maneuver, Semount maneuver, Lempert maneuver, forced prolonged position and Brandt-Daroff exercises. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  3. Radionuclides in the treatment of benign and malignant diseases

    International Nuclear Information System (INIS)

    Samuel, A.M.

    1998-01-01

    Radionuclide therapy has to be considered as an important modality of treatment and to be distinguished from the commonly used terminology of radiotherapy or radiation treatment. The most significant differentiation is the fact that in conventional therapy the source of radiation is outside the patient and is delivered in fractions interspersed at intervals of time, as in so called cobalt therapy or electron beam therapy or deep x-ray therapy. In radionuclide therapy the source of radiation is inside the patient as the radionuclide is administered to the patient via several routes of administration and has to localise in the target tissue. The radiation effects of internal administration leads to a continuous radiation of the tissues and the radiation dose delivered depends on the strength of the radiation emitted by the radionuclide and the half-life, both physical and biological of the latter

    A descriptive and prospective study on the practice of ambulatory major surgery to eliminate benign tumours of the thyroid gland, was carried out in the General Surgery Service of 'Dr. Joaquin Castillo Duany' Teaching Clinical Surgical Hospital in Santiago de Cuba during the years 1996-2008, both included, through a previous clinical evaluation of 74 patients in the Endocrinology Outpatient Department, where it was decided that they could definitely have a surgical treatment. The female sex, the age groups from 31 to 45 years, the hemithyroidectomy as surgical technique, acupuncture as analgesic procedure and the follicular adenoma as cytohistological result prevailed in the case material. Mild complications occurred in 5 members of the sample, but recovery was absolute in all, so that even 72 of them were discharged before the 24 hours. Due to its good acceptance, this surgical method is beneficial for patient and hospital institutions.(author)

    Offshore and coastal wind power is one of the fastest growing industries in many areas, especially those with shallow coastal regions due to the preferable generation conditions available in the regions. As with any expanding industry, there are concerns regarding the potential environmental effects which may be caused by the installation of the offshore wind turbines and their associated infrastructure, including substations and subsea cables. These include the potential impacts on the biological, physical and human environments. This review discusses in detail the potential impacts arising from offshore wind farm construction, and how these may be quantified and addressed through the use of conceptual models. It concludes that while not environmentally benign, the environmental impacts are minor and can be mitigated through good siting practices. In addition, it suggests that there are opportunities for environmental benefits through habitat creation and conservation protection areas. (authors)

    An orbital neoplasm in children is an uncommon clinical finding. Clinical suspicion should be based on many factors, including its location, the nature of onset, associated systemic signs and symptoms, family and social histories, examination findings, and radiographic characteristics. We present two cases of young children of similar age with a rapid-onset orbital mass. In both cases, a circumscribed round lesion was found in the superomedial orbit. An orbital schwannoma, a benign and usually slow growing tumor, was found in the first patient. In contrast, the biopsy of the second patient, who was nearly asymptomatic, revealed a rhabdomyosarcoma. In this review, we have explored the differential diagnosis of relatively common circumscribed round orbital tumors in the pediatric population from both the radiographic (magnetic resonance imaging, MRI) and histopathologic perspectives. A review of highly unusual orbital tumors in children is also provided.

  8. Benign bone-forming lesions: osteoma, osteoid osteoma, and osteoblastoma

    Greenspan, A.

    1993-01-01

    The benign bone lesions - osteoma, osteoid osteoma, and osteoblastoma - are characterized as bone-forming because tumor cells produce osteoid or mature bone. Osteoma is a slow-growing lesion most commonly seen in the paranasal sinuses and in the calvaria. When it occurs in the long bones, it is invariably juxtacortical and may need to be differentiated from, among others, parosteal osteosarcoma, sessile osteochondroma, and a matured juxtacortical focus of myositis ossificans. Osteoid osteoma and osteoblastoma appear histologically very similar. Their clinical presentations and distribution in the skeleton, however, are distinct: osteoid osteoma is usually accompanied by nocturnal pain promptly relieved by salicylates; osteoblastoma arises predominantly in the axial skeleton, spinal lesions constituting one-third of reported cases. This review focuses on the application of the various imaging modalities in the diagnosis, differential diagnosis, and evaluation of these lesions. Their histopathology also is discussed, and their treatment briefly outlined. (orig.)

  9. Management of Intrathoracic Benign Schwannomas of the Brachial Plexus

    2014-01-01

    Full Text Available Primary tumours of the brachial plexus are rare entities. They usually present as extrathoracic masses located in the supraclavicular region. This report describes two cases of benign schwannomas arising from the brachial plexus with an intrathoracic growth. In the first case the tumour was completely intrathoracic and it was hardly removed through a standard posterolateral thoracotomy. In the second case the tumour presented as a cervicomediastinal lesion and it was resected through a one-stage combined supraclavicular incision followed by left video-assisted thoracoscopic surgery. A brachial plexus tumour should be suspected not only in patients with a supraclavicular or cervicomediastinal mass but also in those with intrathoracic apical lesions. A preoperative magnetic resonance imaging study of brachial plexus should be performed in such cases in order to plan the correct surgical approach.

    Full Text Available Benign intracranial hypertension (BIH due to hypothyroidism in children is rare. We report a case of BIH due to hypothyroidism with bilateral sixth nerve palsy in a hemophilic child. The child presented with headache, vomiting, and inward deviation of both eyes for 10 days. On examination, her vision was 20/40 both eyes with restricted abduction in both the eyes. Anterior segments were within normal limits. Fundus showed bilateral disc edema. No marked abnormality was detected by neuroimaging. Baseline investigations were normal except a raised thyroid stimulating hormone. We started the patient on tablet acetazolamide, domperidone, and systemic steroids. Disc edema and ocular movements started improving. We have not come across any such case in literature after thorough PubMed search. The presentation, management, and future problems of this rare case are discussed.

    2016-09-01

    Full Text Available Aim: Oesophageal stricture is one of the causes of dysphagia. It is a condition in which the lumen of oesophagus is narrowed by fibrotic tissue in the oesophageal wall. It is usually caused by inflammation or any other cause that leads to necrotizing of tissue. It is mainly differentiated into benign or malignant. The aim of this article is to answer the clinical question on the effectiveness of oesophageal stenting compared to endoscopic dilatation in patient with benign oesophageal stricture due to ingestion of corrosive substances, who had undergone several endoscopic dilatations. Method: We conducted search of relevant articles using PubMed search engine to answer the clinical question. Keywords being used during the search process were: ("oesophageal stricture"[All Fields] OR "oesophageal stenosis"[All Fields] AND (("dilatation"[All Fields] AND ("stents"[MeSH Terms] OR "stents"[All Fields] OR "stent"[All Fields]. Results were further converged by adding specific filters, which were full text articles and clinical trial. Results: The chosen article was further appraised in order to identify its validity and eligibility to answer the clinical question. We chose to use CONSORT (statement to improve the quality of reporting of RCTs to facilitate the critical appraisal and interpretation of RCTs. Conclusion: Stenting was associated with greater dysphagia, co-medication and adverse events. No randomized controlled trials which compared biodegradable stents with other stents or with balloon dilatation was identified. Lack of adequately robust evidence for effectiveness and cost-effectiveness formed the rationale of this trial.

    The overall program objective is to develop and evaluate environmentally benign agents or products that are effective in the prevention, inhibition, and mitigation of microbially influenced corrosion (MIC) in the internal surfaces of metallic natural gas pipelines. The goal is to develop one or more environmentally benign (a.k.a. ''green'') products that can be applied to maintain the structure and dependability of the natural gas infrastructure. The technical approach for this quarter included the fractionation of extracts prepared from several varieties of pepper plants, and using several solvents, by high performance liquid chromatography (HPLC). A preliminary determination of antimicrobial activities of the new extracts and fractions using a growth inhibition assay, and evaluation of the extracts ability to inhibit biofilm formation was also performed. The analysis of multiple extracts of pepper plants and fractions of extracts of pepper plants obtained by HPLC illustrated that these extracts and fractions are extremely complex mixtures of chemicals. Gas chromatography-mass spectrometry was used to identify the chemical constituents of these extracts and fractions to the greatest degree possible. Analysis of the chemical composition of various extracts of pepper plants has illustrated the complexity of the chemical mixtures present, and while additional work will be performed to further characterize the extracts to identify bioactive compounds the focus of efforts should now shift to an evaluation of the ability of extracts to inhibit corrosion in mixed culture biofilms, and in pure cultures of bacterial types which are known or believed to be important in corrosion.

    Burns and chronic inflammation are well-known circumstances in which malignant transformation may occur during wound healing. There are many reports of malignancies developing from a burn scar; however, there are only a few reports of malignancy arising from chronic inflammation or from the skin of a surgical scar following excision of a benign mass, in any part of the body. There are only twelve reported cases of breast cancer developing from a surgical scar, moreover, there have been no reports in the last 30 years. This case is a recent example of breast cancer developing in a surgical scar that showed subtle changes on sequential sonograms. The imaging findings of this case were subtle but the mass that had been shrinking developed an angular margin in one region. These findings, along with the penetrating vascularity revealed on Doppler, prompted us to proceed to a biopsy of the lesion. It was of critical importance to compare the size and the shape of the lesion with previous ultrasounds in order to exclude malignancy in any iatrogenically altered lesion. Based on this case, we conclude that whenever a subtle change is detected, at a surgical site, a biopsy should be performed. Breast cancer developing from a surgical scar is rare; this type of malignancy has been reported in only 12 cases to date. Herein, we report on a 52-year-old female who developed infiltrating ductal carcinoma in a surgical scar following excision of a benign mass. Two years previously, the patient underwent surgery and radiotherapy for invasive ductal carcinoma of the contralateral breast. The initial appearance of the scar was similar to fat necrosis; it was observed to be progressively shrinking on follow-up sonography. On the two year follow-up ultrasound, the appearance changed, an angular margin and vascularity at the periphery of the scar were noted. A biopsy and subsequent excision of the scar were performed; the diagnosis of infiltrating ductal carcinoma of the scar was

    Our aim is to the report the clinical and histopathological features of benign reactive lymphoid hyperplasia (BRLH) of the conjunctiva in children and the outcomes of treatment. A retrospective chart review was performed for children aged 0-18 years, diagnosed with conjunctival BRLH from January 2000 to December 2013 at two large ophthalmology hospitals in the Middle East. Data were collected on patient demographics, features of the lesions, the site of the lesion, location, adnexal involvement, lymph nodes involvement, local spread, histopathology and molecular genetic studies of the cases (if available), outcomes of treatment and recurrence. There were 24 patients with lymphoid lesions classified as conjunctival BRLH during the 12-year period evaluated in this study. The mean age at diagnosis was 11.6 years. Twenty-three patients were males (96%). Systemic medical history included three patients with bronchial asthma, one patient with Down's syndrome, one patient with generalised skeletal malformation and one patient with gastritis. The initial uncorrected visual acuity was 20/30 or better in 93.5% of the eyes. At presentation, the tumour was unilateral in 12 cases (50%). The conjunctival mass was located on the bulbar conjunctiva in all cases. The mass was present nasally in 96% of lesions. No cases (that were tested) had an infectious aetiology. PCR demonstrated monoclonality suggestive of lymphoma in two cases; however, this did not alter the final diagnosis as BRLH per histopathological criteria and clinical course, CONCLUSIONS: All investigated cases of paediatric conjunctival BRLH had a benign clinical course with no local or systemic dissemination and a male predominance. Recurrence was rare, and in our cohort, it was not associated with malignant transformation. Published by the BMJ Publishing Group Limited.

    Although in benign multiple sclerosis (BMS) locomotor disability is absent or only minimal, subclinical cognitive impairment seems to occur in many cases. Diffusion tensor (DT) MRI enables us to quantify the extent of "actual" tissue damage, which goes undetected when using conventional MRI. Against this background, we investigated the extent of structural brain damage underlying cognitive dysfunction in BMS, with the ultimate aim to move a first step toward a more reliable definition of this disease phenotype. Conventional and DT MRI scans of the brain were acquired from 62 BMS patients. Thirty-six secondary progressive multiple sclerosis (SPMS) patients and 19 healthy subjects served as controls. In BMS patients, neuropsychological tests exploring memory, attention, and frontal lobe functions were administered. Normalized brain volume (NBV), mean diffusivity (MD), and fractional anisotropy (FA) of the normal-appearing white matter (NAWM) and MD of the gray matter (GM) were computed. Twelve BMS patients (19%) fulfilled predefined criteria for cognitive impairment. BMS patients had abnormal MD and FA values from both NAWM and GM. Whereas BMS patients without cognitive impairment had lower T2 LV (p = 0.03), higher NBV (p = 0.006), and lower average GM MD (p = 0.03) than SPMS patients, BMS patients with cognitive impairment did not significantly differ from SPMS patients for any MRI-derived metric. In benign multiple sclerosis (BMS), cognitive dysfunction is associated with severe structural brain damage, which resembles that of patients with a much more disabling disease course. A reliable definition of BMS should, therefore, include the preservation of cognitive functioning as an additional requisite.

Structured expert meeting, using procedures adapted from the nominal group techniques and the Rand consensus method. Valencian School of Health Studies. Forty panellists (74% doctors, 70% from primary care settings) with experience in the management of BPH from 15 departments of the Valencia Health Agency. Three workshops were held simultaneously (examination and diagnosis, drug therapy, and appropriateness and results), and the 15 quality indicators selected by the coordination group were assessed. Eleven of the 15 indicators scored in the range of high relevance. The 5 best rated were: the use of alpha-blockers + 5-alpha reductase inhibitor from certain severity level, digital rectal examination in the initial assessment, follow-up with the International Prostate Symptoms Score (IPSS), the rate of urgent catheterization in Hospital Accident & Emergency Units, initial assessment with the IPSS and the use of alpha-blockers prior to catheter removal for acute retention of urine. Some of the assessed indicators can be useful for incorporation into health information systems. Copyright © 2013 Elsevier España, S.L. All rights reserved.

    Benign positional paroxysmal vertigo (BPPV) is characterized by short-lived episodes of vertigo in association with rapid changes in head position, most commonly extension and rotation of the neck while supine. It has been clinically observed that there is a subgroup of patients in whom the BPPV disease is inherited in an autosomal dominant fashion. However, little is known about the familial/genetic factors that may contribute to a predisposition to develop the disease. We ascertained and performed a genome-wide scan on a three-generation family in which multiple family members developed BPPV. We performed whole genome mapping with 400 microsatellite repeat markers and analyzed this trait using both autosomal dominant and recessive models of inheritance. Two point linkage analysis showed LOD scores of one or greater than one on chromosomes 7, 15, 16 and 20. Independent of the model of inheritance, the highest two-point LOD scores localized to same marker on chromosome 15. Multipoint linkage analysis showed the highest LOD score of 2.84 to markers on chromosome 15 with the autosomal dominant model. Haplotype reconstruction indicates that the BPPV gene in this family maps to a critical chromosomal 15 interval between markers GATA151F03N and GATA85D02. Discovery of a BPPV gene (or genes) will facilitate a better understanding of not only BPPV, but also the vestibular system. In addition, with improved understanding of the pathophysiology the potential development of alternative therapies for BPPV may be possible.

    Background: Benign paroxysmal positional vertigo (BPPV) is linked to vitamin D deficiency. This clinical trial aimed to determine the influence of vitamin D supplementation on intensity of BPPV. Methods: The study population was selected consecutively and the diagnosis of BPPV was made by history and clinical examination and exclusion of other conditions. Intensity of BPVV was assessed based on VAS score (0-10). Serum 25-hydroxyvitamin D (25-OHD) was measured using ELISA method and levels BPPV decreased significantly as compared with control (P=0.001 for both groups) but at endpoint, the intensity of BPPV aggravated and regressed to the baseline value in vitamin D deficient non-treated group (P=0.001) whereas, in vitamin D treated group, improvement of BPPV remained stable and unchanged over the study period. Conclusion: This study indicates that correction of vitamin D deficiency in BPPV provides additional benefit to rehabilitation therapy (Epley maneuver) regarding duration of improvement. These findings suggest serum 25-OHD measurement in recurrent BPPV. PMID:27386060

    2015-01-01

    Benign prostatic hyperplasia (BPH) represents a spectrum of related lower urinary tract symptoms (LUTS). The cost of currently recommended medications and the discontinuation rate due to side effects are significant drawbacks limiting their long-term use in clinical practice. Interventional procedures, considered as the definitive treatment for BPH, carry a significant risk of treatment-related complications in frail patients. These issues have contributed to the emergence of new approaches as alternative options to standard therapies. This paper reviews the recent literature regarding the experimental treatments under investigation and presents the currently available experimental devices and techniques used under local anesthesia for the treatment of LUTS/BPH in the vast majority of cases. Devices for delivery of thermal treatment (microwaves, radiofrequency, high-intensity focused ultrasound, and the Rezum system), mechanical devices (prostatic stent and urethral lift), fractionation of prostatic tissue (histotripsy and aquablation), prostate artery embolization, and intraprostatic drugs are discussed. Evidence for the safety, tolerability, and efficacy of these “minimally invasive procedures” is analyzed. PMID:26317083

    The prostate is an androgen-sensitive organ that needs proper androgen/androgen receptor (AR) signals for normal development. The progression of prostate diseases, including benign prostate hyperplasia (BPH) and prostate cancer (PCa), also needs proper androgen/AR signals. Tissue recombination studies report that stromal, but not epithelial, AR plays more critical roles via the mesenchymal-epithelial interactions to influence the early process of prostate development. However, in BPH and PCa, much more attention has been focused on epithelial AR roles. However, accumulating evidence indicates that stromal AR is also irreplaceable and plays critical roles in prostate disease progression. Herein, we summarize the roles of stromal AR in the development of normal prostate, BPH, and PCa, with evidence from the recent results of in vitro cell line studies, tissue recombination experiments, and AR knockout animal models. Current evidence suggests that stromal AR may play positive roles to promote BPH and PCa progression, and targeting stromal AR selectively with AR degradation enhancer, ASC-J9, may allow development of better therapies with fewer adverse effects to battle BPH and PCa.

    Full Text Available Both in traditional social network and in mobile network environment, the worm is a serious threat, and this threat is growing all the time. Mobile smartphones generally promote the development of mobile network. The traditional antivirus technologies have become powerless when facing mobile networks. The development of benign worms, especially active benign worms and passive benign worms, has become a new network security measure. In this paper, we focused on the spread of worm in mobile environment and proposed the benign worm control and repair mechanism. The control process of mobile benign worms is divided into two stages: the first stage is rapid repair control, which uses active benign worm to deal with malicious worm in the mobile network; when the network is relatively stable, it enters the second stage of postrepair and uses passive mode to optimize the environment for the purpose of controlling the mobile network. Considering whether the existence of benign worm, we simplified the model and analyzed the four situations. Finally, we use simulation to verify the model. This control mechanism for benign worm propagation is of guiding significance to control the network security.

    Malignant peripheral nerve-sheath neoplasms frequently complicate neurofibromatosis causing pain, enlarging masses, or neurologic deficits. However, similar findings sometimes also occur with benign nerve neoplasms. Our study was done retrospectively to determine if imaging techniques can differentiate malignant from benign nerve tumors in neurofibromatosis. Eight patients with symptomatic neoplasms (three benign, five malignant) were studied by CT in eight, MR in six, and 67 Ga-citrate scintigraphy in seven. Uptake of 67 Ga occurred in all five malignant lesions but not in two benign neoplasms studied. On CT or MR, all eight lesions, including three benign neoplasms, showed inhomogeneities. Of five lesions with irregular, infiltrative margins on CT or MR, four were malignant and one was benign. Of three lesions with smooth margins, one was malignant and two were benign. One malignant neoplasm caused irregular bone destruction. Accordingly, CT and MR could not generally distinguish malignant from benign lesions with certainty. However, both CT and MR provided structural delineation to help surgical planning for both types of lesion. 67 Ga scintigraphy appears promising as a screening technique to identify lesions with malignant degeneration in patients with neurofibromatosis. Any area of abnormal radiogallium uptake suggests malignancy warranting further evaluation by CT or MR. Biopsy of any questionable lesion is essential

    Our goal was to assess the value of surgical excision of benign papillomas of the breast diagnosed on percutaneous core biopsy by determining the frequency of upgrade to malignancies and high risk lesions on a final surgical pathology. We reviewed 67 patients who had biopsies yielding benign papilloma and underwent subsequent surgical excision. Surgical pathology of the excised lesions was compared with initial core biopsy pathology results. 54 patients had concordant benign core and excisional pathology. Cancer (ductal carcinoma in situ and invasive ductal carcinoma) was diagnosed in five (7%) patients. Surgery revealed high-risk lesions in 8 (12%) patients, including atypical ductal hyperplasia, atypical lobular hyperplasia, and lobular carcinoma in situ. Cancer and high risk lesions accounted for 13 (19%) upstaging events from benign papilloma diagnosis. Our data suggests that surgical excision is warranted with core pathology of benign papilloma

    Benign osteoblastoma refers to a benign tumor of the bone. Osteoblastoma most commonly affects the vertebrae and long tubular bones, however, in rare cases is observed in the facial bones. The current study presents the case of a 12-year-old female patient with a tumor in the mandibular body. Radiological imaging revealed a lesion with regular contours. The lesion was radically resected and histological analysis of the specimen demonstrated features that are typical of a benign osteoblastoma. The consequential defects of the jaw were reconstructed using titanium implants and autologous bone transplantation. The patient remains disease free subsequent to a five-month follow-up period. The aim of the present report is to present a rare case of benign osteoblastoma of the mandible. This study demonstrated that correct diagnosis and complete surgical excision are important to reduce the risk of recurrence of a benign osteoblastoma. PMID:25364451

    OBJECTIVE: A growing number of studies suggest that some ovarian cancers can arise from benign and borderline ovarian tumors. However, studies on the association between benign and borderline ovarian tumors are lacking. We studied the overall- and histotype-specific risk of borderline ovarian...... tumors among women with a benign ovarian tumor. METHODS: This nationwide cohort study included all Danish women diagnosed with a benign ovarian tumor (n=139,466) during 1978-2012. The cohort was linked to the Danish Pathology Data Bank and standardized incidence ratios (SIR) with 95% confidence intervals...... (CI) were calculated. RESULTS: Women with benign ovarian tumors had increased risks for subsequent borderline ovarian tumors (SIR 1.62, 95% CI 1.43-1.82), and this applied to both serous (SIR 1.69, 95% CI 1.39-2.03) and mucinous (SIR 1.75, 95% CI 1.45-2.10) histotypes of borderline ovarian tumors...

    2017-01-01

    Full Text Available Benign multiple sclerosis is a retrospective diagnosis based primarily on a lack of motor symptom progression. Recent findings that suggest patients with benign multiple sclerosis experience non-motor symptoms highlight the need for a more prospective means to diagnose benign multiple sclerosis early in order to help direct patient care. In this study, we present optical coherence tomography and T cell neurotrophin gene analysis findings in a small number of patients with benign multiple sclerosis. Our results demonstrated that retinal nerve fiber layer was mildly thinned, and T cells had a distinct gene expression profile that included upregulation of interleukin 10 and leukemia inhibitory factor, downregulation of interleukin 6 and neurotensin high affinity receptor 1 (a novel neurotrophin receptor. These findings add evidence for further investigation into optical coherence tomography and mRNA profiling in larger cohorts as a potential means to diagnose benign multiple sclerosis in a more prospective manner.

    A questionnaire was mailed in 3 years (1994, 1995, 1996) to all radiation facilities in Germany, which assessed equipment, indications, number of patients and treatment concepts. A total of 134 (88%) institutions returned all requested data: 22 in East and 112 in West Germany; 30 in university and 104 in community/private hospitals. The average data of each institution and of all institutions were analyzed for frequencies and ratios between different regions and institutions. A mean of 2 (range 1 to 7) megavoltage (Linac/Cobalt 60) and 1.4 (range 0 to 4) orthovoltage units were available per institution; 32 (24%) institutions had no orthovoltage equipment. A mean of 20,082 patients were treated per year: 456 (2%) for inflammatory diseases (221 hidradenitis, 78 nail bed infection, 23 parotitis, 134 not specified), 12,600 (63%) for degenerative diseases (2,711 peritendinitis humeroscapularis, 1,555 epicondylitis humeri, 1,382 heel spur, 2,434 degenerative osteoarthritis, 4,518 not specified), 927 (5%) for hypertrophic diseases (146 Dupuytren's contracture, 382 keloids, 155 Peyronie's disease, 244 not specified), 1,210 (6%) for functional disorders (853 Graves' orbitopathy, 357 not specified), and 4,889 (24%) for other disorders (e.g. 3,680 heterotopic ossification prophylaxis). In univariate analysis, there were significant geographical (West vs East Germany) differences in the use of radiotherapy for inflammatory and degenerative disorders and institutional differences (university vs community/private hospitals) in the use of radiotherapy for hypertrophic and functional disorders (p [de

    Radioiodine is currently used routinely in the treatment of hyperthyroidism including Graves' disease (GD), toxic multinodular goitre (TMNG) and toxic solitary nodule (TSN) but no consensus exists on the most appropriate way to prescribe iodine--fixed dose or calculated doses based on the gland size or turnover of (131)I. We carried out the first nationwide French survey assessing the current practices in radioiodine treatment of hyperthyroidism. A questionnaire was sent to French nuclear medicine hospital units and cancer treatment centres (n=69) about their practices in 2012. Euthyroidism was considered the successful outcome for 33% of respondents, whereas hypothyroidism was the aim in 26% of cases. Fixed activities were the commonest therapeutic approach (60.0% of GD prescribed doses and 72.5% for TMNG and TSN), followed by calculated activities from Marinelli's formula (based on a single uptake value and thyroid volume). The fixed administered dose was chosen from between 1 to 3 levels of standard doses, depending on the patient characteristics. Factors influencing this choice were disease, with a median of 370 MBq for GD and 555 MBq for TSN and TMNG, thyroid volume (59%) and uptake (52%) with (131)I or (99m)Tc. Even physicians using fixed doses performed pretherapeutic thyroid scan (98%). This study shows that practices concerning the prescription of (131)I therapeutic doses are heterogeneous. But the current trend in France, as in Europe, is the administration of fixed doses. The study provides the baseline data for exploring the evolution of French clinical practices. Copyright © 2014.

    Full Text Available Introduction & Objective: Vertigo in the elderly is relatively common, but only a few studies are available. Vestibular rehabilitation (VR therapy is an important therapeutic option in treating patients with significant balance deficits. The purpose of this study was to analyze the effect of vestibular rehabilitation on vertigo symptoms in elderly patients with benign paroxysmal positional vertigo (BPPV. Materials & Methods: In a cross sectional analytic design, 46 patients older than 60 years (aged 61 to 72 years with BPPV who referred to the ENT center of Imam Khomeini Hospital, Ahwaz, were studied. After an otologic evaluation, videonystagmography and dizziness handicap inventory (DHI evaluations were performed for each case. Then, vestibular rehabilitation (VR therapy was carried out by means of Epley maneuver. Efficacy of a VRT was tested by comparing pre-treatment with post-treatment VNG and DHI assessments. The data were analyzed by SPSS 16 software. Results: The average age of the patients was 67.28 ± 4.5 years. VR caused normal Hallpike findings in 31 (67.4 % and noticeable reduction in nystagmus amplitudes in 9 patients. We found a significant correlation between nystagmus amplitudes and DHI scores (r=0.77. The mean DHI scores decreased from 53.26±16.12 points to 15.36±9.23 points (p<0.001 at the end of the treatment course. Conclusion: Our investigation revealed that VR plays an important role in reducing vertigo in at-risk elderly patients. Lack of appropriate treatment in this population may cause a serious balance problem (such as bone fracture and long-term handicap that may interfere with their daily activities.

    The aim of the paper is to report the clinical outcome after prostatic artery embolisation (PAE) in 13 consecutive patients with benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). From May 2012 to October 2013, we performed PAE in 13 consecutive patients (mean age 75.9 years) with BPH and LUTS and refractory to medical therapy; seven patients had an indwelling bladder catheter. Clinical follow-up (mean follow-up time 244 days) was performed using the international prostate symptoms score (IPSS), quality of life (QoL), the international index of erectile function (IIEF), blood prostatic specific antigen (PSA) testing and transrectal prostatic ultrasound (US) scan with volume and weight calculation at 3, 6 and 12 months. Pre-procedural CT angiography (CTA) was done for vascular mapping. Embolisation was performed using Embosphere (300-500 micron). Technical success was defined when selective prostatic arterial embolisation was completed in at least one pelvic side. Clinical success was defined when symptoms and quality of life were improved. PAE was technically successful in 12/13 patients (92%). In one patient, PAE was not performed because of tortuosity and atherosclerosis of iliac arteries. PAE was completed bilaterally in 9/13 (75%) patients and unilaterally in three (27%). All patients removed the bladder catheter from 4 days to 4 weeks after PAE. We obtained a reduction in IPSS (mean, 17.1 points), an increase in IIEF (mean, 2.6 points), an improvement in Qol (mean, 2.6 points) and a volume reduction (mean, 28%) at 12 months. Consistent with the literature, our experience showed the feasibility, safety and efficacy of PAE in the management of patients with LUTS related to BPH. PAE may play an important role in patients in whom medical therapy has failed, who are not candidates for surgery or transurethral prostatic resection (TURP) or refuse any surgical treatment. Larger case series and comparative studies with standard TURP can

    Purpose/Objective: To determine the effectiveness of Radiation Therapy (RT) in the treatment of human immunodeficiency virus (HIV) related benign lymphoepithelial (BLL) of the parotid gland. Materials and Methods: The records of 16 patients treated between 1991 to 1995 with BLL were retrospectively reviewed. Three patients had bilateral disease, thus 19 parotid glands were radiated. Only (2(16)) had AIDS. Virtually all patients were on antiretroviral therapy. There were 11 males and 5 females. The median age was 38 years (range 31 to 58 years). The median duration of parotid enlargement was 1.5 years (range 1 month to 6 years). All patients had biopsy prior to treatment. Histopathology revealed two patterns: solid or cystic. Patient were treated using electron beam RT. The beam energy was determined by computed transaxial tomography. The median dose delivered was 1000 cGy in 5 fractions over 5 days (range 600 cGy to 2160 cGy in daily fractions ranging from 180 cGy to 200 cGy). Results: Six parotid glands achieved a complete response (CR), 5 a partial response (PR), while 8 were non-responders (NR). Our overall response rate was therefore 58% Of the NR's, 3 patients were re-treated. Two achieved a PR, one was an NR. Toxicity was minimal and limited to mild xerostomia. Conclusion: RT in patients with HIV related BLL is well tolerated. Our preliminary results show that while this modality of treatment has marked activity in the solid pattern. Higher doses may be required for large lesions or cystic in nature

    Treatment options for prostate cancer consist of radical prostatectomy, hormonal therapy and radiation therapy. Hormonal and radiation therapy have well-known, often profound, effects on the histological appearance of benign and malignant prostate tissue. Novel therapies including focal ablative treatments, chemotherapies and targeted molecular therapies are beginning to emerge and pathologists will play a central role in documenting the effects of these treatments at the tissue level. As such, knowledge of treatment-related changes and access to clinical information are essential to ensure accurate interpretation and reporting of post-treatment prostate specimens by pathologists.

The pharmacological treatment of the benign prostatic hyperplasia includes the prostatic 5a-reductase inhibitors, the a1-adrenoreceptor blockers, their combined therapy and the phytotherapy. This paper was aimed at presenting the most relevant aspects of the pharmacology of drugs used for treating the benign prostatic hyperplasia, and providing elements to analyze their efficacy, safety and tolerability. To this end, a review was made of the different drugs for the treatment of this pathology and they were grouped according to their mechanism of action. Natural products were included as lipid extracts from Serenoa repens and Pygeum africanum as well as D-004, a lipid extract from Roystonea regia fruits, with proved beneficial effects on the main etiological factors of benign prostatic hyperplasia. D-004 is a prostatic 5a-reductase inhibitor, an a1-adrenoceptor antagonist, a 5-lipooxygenase inhibitor and has antioxidant action, all of which reveals a multifactoral mechanism. The results achieved till now indicate that D-004 is a safe and well-tolerated product.

    To evaluate the morphologic differential diagnosis of benign and malignant ductal breast tumors, as seen on US US findings in 29 pathologically proven cases of ductal breast tumor were retrospectively reviewed. All patients were female and their mean age was 42 years. Nineteen tumors were benign and ten were malignant, and all ductal or cystic lesions showed solid masses. According to the location of the mural nodule, we classified the sonographic appearance of these tumors into three types:intraductal, intracystic and amorphic. The intraductal type was divided into three subtypes:incompletely obstructive, completely obstructive and multiple mural nodules. For the intracystic type, too, three subtypes were designated:the intracystic mural nodule (mural cyst), intracystic mural nodule with the duct (mural cyst+duct) and intracystic multiple mural nodules. The amorphic type is defined as an atypical ductal tumor with the mural nodule extending into adjacent parenchyma. The margin of the duct or cyst was smooth in 68.4% of benign, and irregular in 90% of malignant ductal tumors. Internal echogeneity of the duct or cyst usually showed homogeneity in both benign and malignant tumors. 73.7% of tumors connecting the duct were benign and 50% were malignant. In benign tumors, 52.6% of mural nodule had an irregular margin, while in malignant tumors, the corresponding proportion was 100%;both types usually showed heterogeneous hypoechogeneity. Among benign tumors, the most common morphologic type was the intraductal incompletely obstructive subtype (36.8%);among those that were malignant, the amorphic type was most common, accounting for 40% of tumors. No amorphic type was benign and no incompletely obstructive subtype was malignant. When ductal breast tumors are morphologically classified on the basis of sonographic findings, the intraductal incompletely obstructive subtype suggests benignancy, and the amorphic type, malignancy. The morphologic classification of ductal

    Benign recurrent intrahepatic cholestasis (BRIC) is an autosomal recessive liver disorder characterized by recurrent episodes of jaundice and itching. Episodes of cholestasis last variously from 1 week to several months, may start at any age and usually resolve spontaneously. No effective treatment has been found as yet. We report a case of genetically proven BRIC in a male patient who developed three episodes of pruritus and jaundice at the age of 14, 16 and 19 years. During the third episode, he did not respond to pharmacological medical therapy, and fractionated plasma separation and absorption (FPSA, Prometheus) was performed to manage intractable pruritus. The treatment immediately alleviated pruritus, lowered serum bilirubin concentration and induced sustained remission in the 5-year follow up. FPSA seems to be a safe and effective way of treatment for BRIC in patients with severe pruritus and prolonged jaundice. © 2013 The Japan Society of Hepatology.

    Lower urinary tract symptoms (LUTS) secondary to benign prostatic hypertrophy (BPH) are among the most common medical issues for aging men. Population-based studies suggest that 13.8% of men in their 40s and more than 40% of men over age 60 have BPH. When LUTS are refractory to medical therapy and bothersome enough to warrant surgical intervention, transurethral resection of the prostate and open simple prostatectomy have been the historical reference-standard procedures for decades. Both procedures are highly effective and offer durable improvements in urinary functional outcomes. However, they also have the potential for considerable perioperative complications and morbidity. In an effort to limit surgical morbidity, a variety of minimally invasive surgical techniques to treat BPH have been introduced. Herein we present a comprehensive, evidence-based review of the efficacy and safety profile of modern minimally invasive treatments for large-gland BPH.

    The diagnosis of cutaneous panarteritis nodosa, a local, isolated condition of good prognosis, requires the elimination of any systemic involvement. Two personal cases, together with a review of the literature, serve to demonstrate the benign nature of the condition, with the absence of systemic complications during a mean medical follow-up of 9 years. However, the condition is not entirely innocuous since it required the administration of corticosteroids in 71% of cases. The outcome was complete recovery in 32% of cases, and improvement or stabilisation in 51%, with no information provided in 16%. Complete recovery was obtained in the author's two cases: one spontaneously and one with corticosteroid therapy. The good prognosis justifies the suggestion of a relatively non-invasive diagnostic assessment. Medical follow-up is required if symptomatology persists or if steroids are prescribed, but is not necessary when there is complete recovery.

    The overall program objective is to develop and evaluate environmentally benign agents or products that are effective in the prevention, inhibition, and mitigation of microbially influenced corrosion (MIC) in the internal surfaces of metallic natural gas pipelines. The goal is to develop one or more environmentally benign (a.k.a. ''green'') products that can be applied to maintain the structure and dependability of the natural gas infrastructure. The technical approach for this quarter includes the application of the method of fractionation of the extracts by high performance liquid chromatography (HPLC); determination of antimicrobial activities of the new extracts and fractions using a growth inhibition assay, and evaluation of the extracts' ability to inhibit biofilm formation. We initiated the delivery system for these new biocides in the test cell and in mixtures of foam components and biocides/anti-biofilms. A total of 51 fractions collected by HPLC from crude extracts that were obtained from three varieties of Capsicum sp. (Serrano, Habanero, Chile de Arbol) were subjected to growth inhibition tests against two SRB strains, D. vulgaris and D. desulfuricans. Five fractions showed growth inhibition against both strains while seven inhibited D. desulfuricans only. The crude extracts did not show growth inhibition on both strains but were proven to be potent in preventing the formation of biofilm. Growth inhibition tests of the same set of crude extracts against Comamonas denitrificans did not show positive results. The fractions will be subjected to biofilm inhibition and dissociation assay as well. The delivery system to be evaluated first was foam. The ''foam pig'' components of surfactants and water were tested with the biocide addition. The first chemical and physical parameters to be tested were pH and surfactants. Tests using the fractionated pepper extracts are progressing rapidly. Gas chromatographic analysis

    Overexpression of transketolase-like 1 protein TKTL1 in cancer cells has been reported to correlate with enhanced glycolysis and lactic acid production. Furthermore, enhanced TKTL1 expression was put into context with resistance to chemotherapy and ionizing radiation. Here, a panel of human malign and benign cells, which cover a broad range of chemotherapy and radiation resistance as well as reliance on glucose metabolism, was analyzed in vitro for TKTL1 expression. 17 malign and three benign cell lines were characterized according to their expression of TKTL1 on the protein level with three commercially available anti-TKTL1 antibodies utilizing immunohistochemistry and Western blot, as well as on mRNA level with three published primer pairs for RT-qPCR. Furthermore, sensitivities to paclitaxel, cisplatin and ionizing radiation were assessed in cell survival assays. Glucose consumption and lactate production were quantified as surrogates for the "Warburg effect". Considerable amounts of tktl1 mRNA and TKTL1 protein were detected only upon stable transfection of the human embryonic kidney cell line HEK293 with an expression plasmid for human TKTL1. Beyond that, weak expression of endogenous tktl1 mRNA was measured in the cell lines JAR and U251. Western blot analysis of JAR and U251 cells did not detect TKTL1 at the expected size of 65 kDa with all three antibodies specific for TKTL1 protein and immunohistochemical staining was observed with antibody JFC12T10 only. All other cell lines tested here revealed expression of tktl1 mRNA below detection limits and were negative for TKTL1 protein. However, in all cell lines including TKTL1-negative HEK293-control cells, antibody JFC12T10 detected multiple proteins with different molecular weights. Importantly, JAR and U251 did neither demonstrate an outstanding production of lactic acid nor increased resistance against chemotherapeutics or to ionizing radiation, respectively.

    Laser interstitial thermotherapy (LITT) is a relatively new focal therapy technique for the ablation of localized prostate cancer. However, very little is known about the specific effects of LITT within the ablation zone and the surrounding normal tissue regions. For instance, it is important to be able to assess the extent of residual cancer within the prostate following LITT, which may be masked by thermally induced benign necrotic changes. Fortunately LITT is MRI compatible and hence this allows for quantitatively assessing LITT induced changes via multi-parametric MRI. Of course definite validation of any LITT induced changes on MRI requires confirmation via histopathology. The aim of this study was to quantitatively assess and distinguish the imaging characteristics of prostate cancer and benign confounding treatment changes following LITTon 3 Tesla multi-parametric MRI by carefully mapping the treatment related changes from the ex vivo surgically resected histopathologic specimens onto the pre-operative in vivo imaging. A better understanding of the imaging characteristics of residual disease and successfully ablated tissue might lead to improved treatment monitoring and as such patient prognosis. A unique clinical trial at the Radboud University Medical Center, in which 3 patients underwent a prostatectomy after LITT treatment, yielded ex-vivo histopathologic specimens along with pre- and post-LITT MRI. Using this data we (1) identified the computer extracted MRI signatures associated with treatment effects including benign necrotic changes and residual disease and (2) subsequently evaluated the computer extracted MRI features previously identified in distinguishing LITT induced changes in the ablated area relative to the residual disease. Towards this end first a pathologist annotated the ablated area and the residual disease on the ex-vivo histology and then we transferred the annotations to the post-LITT MRI using semi-automatic elastic registration.

    To assess the diagnostic value of dynamic perfusion MR imaging for differentiation between benign and malignant musculoskeletal lesions. Dynamic perfusion MR imaging was performed using a 3.0 T system in 32 female and 30 male patients (aged 10-90 years, mean age, 43 years). Following the assessment of the precontrast imaging, a dynamic study was performed. This dynamic technique allowed for 638 images to be obtained at 11 levels throughout the lesion. Twenty-eight lesions originated within bone (8 benign, 20 malignant), whereas 34 lesions were of soft tissue origin (22 benign, 12 malignant). The final diagnosis was histopathologically confirmed in all patients. To differentiate between benign and malignant lesions, we analyzed the four parameters: (maximal relative enhancement (MRE), time to peak (TTP), wash in rate (WI), steepest slope (SS) and the distribution of time intensity curve (TIC) patterns. The TTP, WI, and SS values of malignant lesions were statistically significant from those of benign lesions(ρ < 0.05). However, the difference for the MRE values was not statistically significant. The distribution of TIC patterns was a helpful indicator of benign or malignant state, however the difference between the two states was not significant. Dynamic perfusion MR imaging is a helpful tool in differentiating benign and malignant musculoskeletal lesions

    Full Text Available Abstract Background Although Helicobacter Pylori (HP was detected in some cases of chronic laryngitis, the results were not confirmed by polymerase chain reaction (PCR. By this time, it has not been found in laryngeal lesions by in house PCR, the most sensitive method for detecting the genome tracks. Regarding the previous results and also few numbers of studies about the presence of HP in benign laryngeal lesions, specifically by PCR, we aimed to investigate the presence of HP in benign laryngeal lesions by in-house PCR. Methods The samples were taken from 55 patients with benign laryngeal lesions and frozen in −20°C. One milliliter (ml of lysis buffer was added to 100 mg (mg of each sample and the tube was placed in 56°C overnight. Then DNA extraction was carried out. Results To find HP DNA, in-house PCR was performed that revealed 5 positive results among 55 patients with benign laryngeal lesions. Of them, 3 were polyp, 1 was nodule and 1 was papilloma. Conclusion Although the number of positive results was not a lot in this study, it was in contrast with previous studies which could not find any HP tracks in benign laryngeal lesions by other methods. More studies about the prevalence of HP in benign laryngeal lesions improve judging about the effect of this infection on benign laryngeal lesions.

    Abstract Introduction Benign cystic mesothelioma or peritoneal inclusion cysts are rare benign abdominal tumors usually occurring in females of reproductive age. These cysts present as abdominopelvic pain or masses but are often found on imaging or incidentally at surgery. They are commonly associated with pelvic inflammatory disease, endometriosis, or ovarian cysts. We report what is, to the best of our knowledge, the first case of a benign cystic mesothelioma complicating a presentation of acute appendicitis. Case Presentation A 19-year-old Irish Caucasian woman presented with abdominal pain. Imaging suggested appendicitis with abscess formation. She was treated with antibiotics and scheduled for interval appendicectomy. At laparoscopy, an unusual cystic mass was found arising from the appendix. Histology revealed benign cystic mesothelioma. Conclusion We report what is, to the best of our knowledge, the first case of a benign cystic mesothelioma arising from the appendix and complicating a presentation of acute appendicitis. This is a benign pathology, but recurrences are not uncommon. Benign cystic mesothelioma should be included in the differential when investigating pelvic masses or abscesses associated with either appendicitis or pelvic inflammatory disease in women.

    Ovarian carcinoma is a leading cause of death in gynecological malignancy. Ovarian surface epithelial serous and mucinous tumours are classified as benign, borderline, and malignant. The identification of borderline tumours most likely to act aggressively remains an important clinical issue. This work aimed to study DNA ploidy and nuclear area in ovarian serous and mucinous; benign, borderline and malignant tumours. This study included forty ovarian (23 serous and 17 mucinous) tumours. Paraffin blocks were sectioned; stained with haematoxylin and eosin for histopathologic and morphometric studies and with blue feulgen for DNA analysis. All four serous and six out of nine mucinous benign tumours were diploid. All eight serous and five mucinous malignant tumours were aneuploid. Nine of eleven (81.8%) serous and all three mucinous borderline tumours were aneuploid. There were highly significant differences in mean aneuploid cells percentage between serous benign (1.5%), borderline (45.6%) and malignant (74.5%) (p = 0.0001) and between mucinous benign (13.2%) and both borderline (63.7%) and malignant (68.4%) groups (p = 0.0001). There were significant differences in nuclear area between serous benign (26.191%), borderline (45.619%) and malignant (67.634 %) and a significant positive correlation between mean percentage aneuploid value and mean nuclear area in all serous and mucinous groups. We suggest that DNA ploidy and nuclear area combined, may be adjuncts to histopathology; in ovarian serous and mucinous benign, borderline and malignant neoplasms; identifying the aggressive borderline tumours.

    Benign prostate hyperplasia (BPH) is a pervasive condition of enlargement of the male prostate gland which leads to several urinary difficulties ranging from hesitancy to incontinence to kidney dysfunction in severe cases. Currently the most common therapy is transurethral resection of the prostate (TURP) utilizing an electrosurgical device. Although TURP is largely successful, new BPH therapy methods are desired to reduce the cost and recovery time, improve the success rate, and reduce side effects. Recently, lasers have been introduced for this purpose. Indigo Medical Inc. is currently engaged in the development, testing, and preparation for sales of a new diode laser based BPH therapy system. The development is based on laboratory experiments, animal studies, and a limited FDA-approved clinical trial in the US and in other countries. The addition of sophisticated numerical modeling, of the sort that has been highly developed at Lawrence Livermore National Laboratory, can greatly aid in the design of the system and treatment protocol. The benefits to DOE include the maintenance and advancement of numerical modeling expertise in radiation-matter interactions of the sort essential for the stockpile stewardship, inertial confinement fusion, and advanced manufacturing, and the push on advanced scientific computational methods, ultimately in areas such as 3-D transport.
