    Ragone, Azzurra; di Noia, Tommaso; di Sciascio, Eugenio; Donini, Francesco M.

    We present a semantic-based approach to multi-issue bilateral negotiation for e-commerce. We use Description Logics to model advertisements, and relations among issues as axioms in a TBox. We then introduce a logic-based alternating-offers protocol, able to handle conflicting information, that merges non-standard reasoning services in Description Logics with utility thoery to find the most suitable agreements. We illustrate and motivate the theoretical framework, the logical language, and the negotiation protocol.

    Among the publications of CDC Climat Research, 'Climate Briefs' presents, in a few pages, hot topics in climate change policy. This issue addresses the following points: In order to achieve its long-term emission reduction target following the Fukushima incident, Japan would rely more heavily on international offsetting activities. Concurrent to vigorous proposals to reform the CDM, Japan is also promoting an offset crediting scheme through bilateral agreements with developing countries as a post-2012 market mechanism. Despite potential benefits, issues relating to the accounting rules, environmental integrity and implications to carbon markets warrant further consideration prior to international recognition

    Ragone, Azzurra; Ruta, Michele; di Sciascio, Eugenio; Donini, Francesco M.

    We present an approach to multi-issue bilateral negotiation for mobile commerce scenarios. The negotiation mechanism has been integrated in a semantic-based application layer enhancing both RFID and Bluetooth wireless standards. OWL DL has been used to model advertisements and relationships among issues within a shared common ontology. Finally, non standard inference services integrated with utility theory help in finding suitable agreements. We illustrate and motivate the provided theoretical framework in a wireless commerce case study.

    Among non-oil and in trade arena, drug has always been strategic importance and most government especially industrialized countries pay special attention to its production and trade issues. Thus, having a comprehensive view from economic perspective to this section is essential for suggesting intervention. This was a descriptive-analytical and panel study. In this study, gravity model is used to estimate Iran's bilateral intra-industry trade in pharmaceutical products in the 2001-2012 periods. To illustrate the extent of pharmaceutical's intra-industry trade between Iran and its major trading partners, the explanatory variables of market size, income, factor endowments, distance, cultural contributions, and similarities and also special trade arrangements have been applied. Analysis of factors affecting Iran's bilateral intra-industry trade in pharmaceutical industry showed that the average GDP and cultural similarities had a significant positive impact on Iran's bilateral IIT, while the difference in GDP has a negative and significant effect. Coefficients obtained for the geographical distance and the average ratio of total capital to the labor force is not consistent with theoretical expectations. Special trade arrangements did not have significant impact on the extent of bilateral intra-industry trade between Iran and its trading partners. The knowledge of the intra-industry trade between Iran and its trade partners make integration between the countries. Factors affecting this type of trade pattern underlie its development in trade relationship. Therefore, the findings of this study would be useful in helping to develop and implement policies for the expansion of the pharmaceutical trade.

    2012-05-01

    Fractures of the skull base can cause lower cranial nerve palsies because of involvement of the nerves as they traverse the skull. A variety of syndromes have been described, often involving multiple nerves. These are most commonly unilateral, and only a handful of cases of bilateral cranial nerve involvement have been reported. We describe a 64-year-old man with occipital condylar fracture complicated by bilateral palsies of IX and X nerves associated with dramatic physiological derangement causing severe management challenges. Apart from debilitating postural hypotension, he developed dysphagia, severe gastrointestinal dysmotility, issues with airway protection as well as airway obstruction, increased oropharyngeal secretions and variable respiratory control. This is the first report of a patient with traumatic bilateral cranial nerve IX and X nerve palsies. This detailed report and the summary of all 6 previous case reports of traumatic bilateral lower cranial nerve palsies illustrate clinical features, treatment strategies, and outcomes of these rare events.

    Full Text Available Presented modern literature data on the features of the pathogenesis, course, clinical and morphological expression and tumor characteristics, parameters and nodal metastasis of hematogenous bilateral breast cancer. Highlight the results of domestic and foreign studies in recent years to determine the prognostic factors and recurrence of synchronous and metachronous bilateral breast cancer. It was revealed that the frequency of bilateral breast tumor lesions varies widely, ranging from 0.1 to 20%, with metachronous tumors recorded significantly higher (69.6% than the synchronous (22.7%. The probability of occurrence of metachronous breast cancer is higher in women with a family history, as well as if they have a gene mutation BRCA-1. Found that the most common histological type of breast tumor with bilateral lesions is invasive ductal. However, the incidence of invasive lobular cancer and non-invasive lobular cancer is slightly higher among synchronous bilateral cancer compared with unilateral disease. Studies have shown that in a double-sided synchronous breast cancer tumor, as a rule, has a lower degree of differentiation, and the higher the expression level of estrogen receptors and progesterone receptors. Relevance of the issue because the identification of patterns in the study of lymphatic and hematogenous features bilateral metastasis of mammary tumors provides a basis for speculation about the differences in the progression of neoplastic disease in these groups and is a cause for further detailed research in this area to identify and evaluate the prognosis and also the choice of tactics of such patients.

    2011-07-01

    We present a patient with a novel finding of bilateral mucosal bridges, bilateral type III trans-vocal fold sulci vocales, and a vocal fold polyp. Although sulci and mucosal bridges occur in the vocal folds, it is rare to find multiples of these lesions in a single patient, and it is even more uncommon when they occur in conjunction with a vocal fold polyp. To our knowledge, this is the first description of a vocal fold polyp in combination with multiple vocal fold bridges and multiple type III sulci vocales in a single patient. To describe and visually present the diagnosis and treatment of a patient with an intracordal polyp, bilateral mucosal bridges, as well as bilateral type III trans-vocal fold sulci vocales. Presentation of a set of high definition intraoperative photos displaying the extent of the vocal fold lesions and the resection of the intracordal polyp. This patient presented with only 6 months of significant dysphonia. It was felt that the recent change in voice was because of the polyp and not the bridges or sulci vocales. Considering the patient's presentation and the possible morbidity of resection of mucosal bridges and sulci, only the polyp was excised. Postoperatively, the patient's voice returned to his acceptable mild baseline dysphonia, and the benefit has persisted 6 months postoperatively. The combination of bilateral mucosal bridges, bilateral type III sulcus vocalis, and an intracordal polyp in one patient is rare if not novel. Treatment of the polyp alone returned the patient's voice to his lifelong baseline of mild dysphonia. Copyright © 2011 The Voice Foundation. Published by Mosby, Inc. All rights reserved.

    With the emphasis on bilateral hearing nowadays, bilateral cochlear implantation has been tried out for bilateral aural rehabilitation. Bilateral sensorineural hearing loss caused by head trauma can get help from cochlear implantation. We present the case of a 44-year-old man with bilateral otic capsule violating temporal bone fractures due to head trauma. The patient demonstrated much improved audiometric and psychoacoustic performance after bilateral cochlear implantation. We believe bilateral cochlear implantation in such patient can be a very effective tool for rehabilitation. Copyright © 2011 Elsevier Inc. All rights reserved.

    Interest in the association of epilepsy and pseudobulbar palsy was rekindled since the identification through magnetic resonance imaging (MRI) of bilateral perisylvian polymicrogyria (PMG). Seizures are often intractable, but resective epilepsy surgery has not been recommended. However, a similar clinical picture can be encountered in patients with bilateral perisylvian destructive lesions, which fit the description of ulegyria (ULG). We report a series of patients with epilepsy and pseudobulbar palsy due to bilateral perisylvian ULG (BP-ULG), show that hippocampal sclerosis (HS) is often associated and highlight the fact that in this entity, unlike in malformative bilateral perisylvian PMG, seizures may be surgically treated. The motor, cognitive, epileptologic, and imaging features of 12 patients with perisylvian ULG followed at three institutions are described. For patients with refractory seizures, we detail extracranial and intracranial electrographic recordings, surgical strategies, histopathologic analyses of the resected tissue, and outcome of surgical treatment. Descriptive statistics were used for quantitative and categorical variables. Student's t-test was used to compare means, and a p Dual pathology with associated unilateral HS was present in four. One patient with dual pathology had a temporolimbic electroclinical picture and had an anterior temporal lobectomy (ATL) based upon noninvasive evaluation. The other four had ictal semiology suggesting involvement of both temporolimbic and perisylvian cortex. Intracranial electroencephalography (EEG) showed concomitant seizure onset in the anterior temporal region and in the ipsilateral ULG in three of the four with dual pathology and in the ulegyric cortex in the one without HS. Resection guided by a combination of semiology, MRI, and extra and intracranial EEG led to complete seizure control in two and almost complete seizure control (Engel class II) in two other patients. The only surgical failure was an

    In the first part of this work we have dealt with some issues that are relevant in the area of nucleonic resonances within different constituent quark models. In this context we have concentrated on the theoretical description of Pi and Nu decays for N and Delta resonances. The results obtained point to the necessity of a more microscopic description of the dynamics which is at the same time responsible for the binding of quarks inside baryons and the decay of the latter ones. In the second part we have contributed to the study of crossed two-boson exchanges in the Bethe-Salpeter equation as well as to the investigation of different three-dimensional approaches that follow from the Bethe-Salpeter equation in a certain non-relativistic reduction scheme. These one include in particular an equation whose interaction depends on the total energy of the system. It was shown that such an equation is able to account for a certain number of properties of Bethe-Salpeter equation, in particular, that there also arise abnormal solutions in such an approach.

    2008-01-01

    Most electricity markets around the world are a combination of bilateral and pool markets, such as NordPool and NYPOOL. In these models, market participants bid into the pool and also make bilateral contracts with each other. This paper addressed the issue of congestion management and security cost allocation in a power pool market model. The basic idea of security cost allocation is to divide the incurred security cost due to congestion relief into pool and bilateral market based on their flow contribution to the congested line. A newly proposed security cost allocation strategy of the combined bilateral-pool market was also presented along with case studies using IEEE-14 bus system that tested the proposed method. Using the proposed method, it was shown that security costs are allocated to market participants at different prices which reflect the load contribution to the security problem. This solves the problem of the uniform security cost allocation in a pure pool market system having uniform pricing, and provides a proper security signal to market participants. 11 refs., 3 tabs., 4 figs

    The current international energy trade governance system is fragmented and multi-layered. Streamlining it for greater legal cohesiveness and international political and economic cooperation would promote global energy security. The current article explores three levels of energy trade governance: multilateral, regional and bilateral. Most energy-rich countries are part of the multilateral trading system, which is institutionalized by the World Trade Organization (WTO). The article analyzes the multilateral energy trade governance system by focusing on the WTO and energy transportation issues. Regionally, the article focuses on five major regional agreements and their energy-related aspects and examines the various causes that explain the proliferation of regional trade agreements, their compatibility with WTO law, and then provides several examples of regional energy trade governance throughout the world. When it comes to bilateral energy trade governance, this article only addresses the European Union’s (EU) bilateral energy trade relations. The article explores ways in which gaps could be filled and overlaps eliminated whilst remaining true to the high-level normative framework, concentrating on those measures that would enhance EU energy security.

  1. [Bilateral cochlear implants].

    2017-07-01

    Cochlear implants (CI) are standard for the hearing rehabilitation of severe to profound deafness. Nowadays, if bilaterally indicated, bilateral implantation is usually recommended (in accordance with German guidelines). Bilateral implantation enables better speech discrimination in quiet and in noise, and restores directional and spatial hearing. Children with bilateral CI are able to undergo hearing-based hearing and speech development. Within the scope of their individual possibilities, bilaterally implanted children develop faster than children with unilateral CI and attain, e.g., a larger vocabulary within a certain time interval. Only bilateral implantation allows "binaural hearing," with all the benefits that people with normal hearing profit from, namely: better speech discrimination in quiet and in noise, as well as directional and spatial hearing. Naturally, the developments take time. Binaural CI users benefit from the same effects as normal hearing persons: head shadow effect, squelch effect, and summation and redundancy effects. Sequential CI fitting is not necessarily disadvantageous-both simultaneously and sequentially fitted patients benefit in a similar way. For children, earliest possible fitting and shortest possible interval between the two surgeries seems to positively influence the outcome if bilateral CI are indicated.

    Full Text Available CONTEXT AND OBJECTIVES: Package leaflets are necessary for safe use of medicines. The aims of the present study were: 1 to assess the compliance between the content of the package leaflets and the specifications of the pharmaceutical regulations; and 2 to identify potential safety issues for patients. DESIGN AND SETTING: Qualitative descriptive study, involving all the package leaflets of branded medicines from the three most consumed therapeutic groups in Portugal, analyzed in the Department of Pharmacoepidemiology, School of Pharmacy, University of Lisbon. METHODS: A checklist validated through an expert consensus process was used to gather the data. The content of each package leaflet in the sample was classified as compliant or non-compliant with compulsory regulatory issues (i.e. stated dosage and descriptions of adverse reactions and optional regulatory issues (i.e. adverse reaction frequency, symptoms and procedures in cases of overdose. RESULTS: A total of 651 package leaflets were identified. Overall, the package leaflets were found to be compliant with the compulsory regulatory issues. However, the optional regulatory issues were only addressed in around half of the sample of package leaflets, which made it possible to identify some situations of potentially compromised drug safety. CONCLUSION: Ideally, the methodologies for package leaflet approval should be reviewed and optimized as a way of ensuring the inclusion of the minimum essential information for safe use of medicines.

  4. Bilateral patching in retinal detachment: fluid mechanics and retinal "settling".

    Science.gov (United States)

    Foster, William J

    2011-07-20

    When a patient suffers a retinal detachment and surgery is delayed, it is known clinically that bilaterally patching the patient may allow the retina to partially reattach or "settle." Although this procedure has been performed since the 1860s, there is still debate as to how such a maneuver facilitates the reattachment of the retina. Finite element calculations using commercially available analysis software are used to elucidate the influence of reduction in eye movement caused by bilateral patching on the flow of subretinal fluid in a physical model of retinal detachment. It was found that by coupling fluid mechanics with structural mechanics, a physically consistent explanation of increased retinal detachment with eye movements can be found in the case of traction on the retinal hole. Large eye movements increase vitreous traction and detachment forces on the edge of the retinal hole, creating a subretinal vacuum and facilitating increased subretinal fluid. Alternative models, in which intraocular fluid flow is redirected into the subretinal space, are not consistent with these simulations. The results of these simulations explain the physical principles behind bilateral patching and provide insight that can be used clinically. In particular, as is known clinically, bilateral patching may facilitate a decrease in the height of a retinal detachment. The results described here provide a description of a physical mechanism underlying this technique. The findings of this study may aid in deciding whether to bilaterally patch patients and in counseling patients on pre- and postoperative care.

    To study the development of the bilateral benefit in children using bilateral cochlear implants by measurements of speech recognition and sound localization. Bilateral and unilateral speech recognition in quiet, in multi-source noise, and horizontal sound localization was measured at three occasions during a two-year period, without controlling for age or implant experience. Longitudinal and cross-sectional analyses were performed. Results were compared to cross-sectional data from children with normal hearing. Seventy-eight children aged 5.1-11.9 years, with a mean bilateral cochlear implant experience of 3.3 years and a mean age of 7.8 years, at inclusion in the study. Thirty children with normal hearing aged 4.8-9.0 years provided normative data. For children with cochlear implants, bilateral and unilateral speech recognition in quiet was comparable whereas a bilateral benefit for speech recognition in noise and sound localization was found at all three test occasions. Absolute performance was lower than in children with normal hearing. Early bilateral implantation facilitated sound localization. A bilateral benefit for speech recognition in noise and sound localization continues to exist over time for children with bilateral cochlear implants, but no relative improvement is found after three years of bilateral cochlear implant experience.

  9. Improving efficiency in bilateral emission trading

    1998-01-01

    When environmental damages from emissions are spatially nonuniform, permit trading has been modeled most often as a 'pollution offset program' in which emission permits are traded between agents, subject to constraints on ambient air quality. To date the institution envisioned to implement such a program involves trading on a bilateral and sequential basis. However, simulation studies indicate that the sequence of trades may alter the outcome and undermine the cost savings from a pollution offset program. This paper identifies a design for the trading institution that tends to overcome this phenomenon and improve the efficiency of equilibria obtained in a simulation model. We model a bilateral trading process for the reduction of sulfur dioxide emissions with a stochastic description of the sequence of trades within groups of nations in Europe. When trading takes place between disaggregated, stylistic representations of economic enterprises, rather than between national governments, a significantly greater portion of potential savings is achieved. In fact, under most sets of assumptions, approximate first order stochastic dominance is achieved wherein the more decentralized the trading agents, the greater the expected savings from a trading program. 4 figs., 2 tabs., 31 refs

    The aim of the study was to investigate whether children with bilateral conductive hearing loss benefit from their second device (i.e., the bilateral bone conduction device [BCD]). Speech recognition in noise was assessed in 10 children fitted with bilateral BCDs during childhood. Speech recognition was measured in 2 conditions with both BCDs active. Spatial resolution was tested with the Minimum Audible Angle test in the bilateral and monaural listening conditions. Children demonstrated an improvement in speech recognition when speech was presented from the front and noise was presented from the right-hand side as compared with both speech and noise being presented from the front. The minimum audible angle decreased from 57° in the best monaural condition to 13° in the bilateral condition. The audiological outcomes demonstrate the advantage of bilateral BCD fitting in children with bilateral conductive hearing loss.

    1996-01-01

    Purpose: To assess outcome of patients with bilateral breast carcinoma treated with bilateral breast conserving surgery with radiation therapy (CS+RT) and to compare their outcome to (1) patients with unilateral disease treated with CS+RT and (2) patients of comparable stage treated with bilateral mastectomy. Methods and Materials: The charts of all patients with the diagnosis of breast cancer treated with CS+RT at our facilities prior to 1993 were reviewed to identify patients with bilateral disease. A total of 50 patients identified as having bilateral breast cancer conservatively treated(BCT) served as the index population. Out of the 50 patients, 23 presented with synchronous bilateral breast cancer and 27 presented with metachronous bilateral breast cancer. A group of 984 patients with unilateral breast cancer (UCT) treated with CS+RT during the same time interval served as the first control group. A second control group was comprised of 42 patients with early stage bilateral breast cancer presenting during the same time interval treated with bilateral mastectomy (BMAST). Patients who had locally advanced disease in either breast or those patients treated exclusively for lobular carcinoma in situ in either breast were excluded from the analysis. Of the 42 BMAST patients, 33 presented with synchronous disease and nine presented with metachronous disease. Local-regional relapse rates were calculated from the date of treatment of each breast. Overall survival and distant relapse rates were calculated from the date of treatment of the second breast cancer diagnosed. Survival curves were calculated via the life table method and statistical comparisons between curves were performed using the log rank statistic. Chi square analysis was used to detect differences between categorical variables. Results: As of December 1995, the median follow-up of the bilateral conservatively treated patient population was 9.4 years. No statistically significant differences were noted

    We evaluate 311 breast cancer patients admitted to Yong Dong Severance Hospital Between October 1st 1985 and July 31th 1989, and were able to obtain the following conclusions. 1) There were 14(4.5%) bilateral breast cancers among the 311 confirmed breast cancers. 2) Among the bilateral breast cancers, 5(31%) were synchronous and 9(69%) metachronous. 3) Average interval between the first and the second breast cancer in metachronous cancers was 3.8 year(1-15 years). 4) Bilateral breast cancer was most prevalent in the fifth decade (6/14) with the mean age of 47 years. 5) Film mammogram and sonomammogram showed findings of typical breast malignancies. There was no additional specific findings for each cancer in bilateral breast cancers which was different from unilateral cancers. Therefor, in the patients with unilateral breast cancer, possibility of the second lesion in the contralateral side must be considered and a close follow up observation should be done for at least 3 years

    To present a case of a patient with simultaneous bilateral retinal detachments treated successfully with bilateral pneumatic retinopexy. Case report. This is a case of an otherwise healthy 49-year-old woman with no remarkable ocular history that presented with simultaneous phakic superior bilateral rhegmatogenous retinal detachments. Treatment on the day of presentation included laser retinopexy of the inferior lattice degeneration in the left eye and bilateral intravitreal injection of 0.4 cc of 100% C3F8 gas preceded by topical anesthesia. After 48 hours, both retinas were completely reattached, and bilateral laser retinopexy was performed to the superior tears. After a review of the literature, the authors could find only two reported cases of simultaneous bilateral retinal detachments treated successfully with pneumatic retinopexy. This is not only a cost-effective procedure but also allows treatment when there is no immediate operating room availability or a when a quick referral for surgery is not possible.

    Full Text Available Orthodontic treatment aims to improve esthetics, function and structural balance. In some rare circumstances, the clinician may not be able to achieve the ideal treatment goals because of complex multiple orthodontic problems, which may include significant mutilation of the dentition. Brodie bite, a complete buccal posterior crossbite is a problem, which confronts clinicians with often complex variable etiology. The following case report demonstrates treatment of bilateral buccal nonocclusion that is mainly due to a maxillary dental arch issue rather than mandibular retrognathism.

  20. Fluoroquinolone-induced bilateral rupture of the Achilles tendon: clinical and sonographic findings

    2011-09-01

    Full Text Available The fluoroquinolones are antibiotics widely used in the clinical practice. The concomitant use of corticosteroids and fluoroquinolones in elderly patients is recognised as a risk factor for developing clinically relevant tendon lesions. Fluoroquinolone-induced tendinopathy is underreported in the literature. Clinical case. A 67-year-old man, came to our observation complaining of 5 days history of bilateral heel pain. The patient had a medical history of sarcoidosis and was treated with a daily dose of 5 mg of prednisone. He was initially given oral levofloxacin (500 mg/die for 10 days, because of an acute respiratory infection. Two days before the end of the antibiotic therapy, he developed bilateral heel pain. He denied any history of trauma. Physical examination revealed swelling and marked tenderness with mild palpation of the Achilles tendons at the calcaneal insertion. The ultrasound evaluation of the Achilles tendons revealed the following main abnormalities: diffuse thickening, loss of the “fibrillar” echotexture, blurred margins, and bilateral partial tendon tears. Discussion. Bilateral Achilles tendon pain and rupture has been described as a rare adverse effect of fluoroquinolone treatment. Most of the fluoroquinolone-induced tendinopathies of the Achilles tendon are due to ciprofloxacin. To the best of our knowledge, this is the first description of bilateral Achilles tendon rupture due to levofloxacin. The risk/benefit ratio of the fluoroquinolones should be carefully considered and these drugs should be prescribed cautiously in elderly patients treated with corticosteroids. This case can be regarded as a representative example of the potential clinical efficacy of sonography in daily rheumatological practise.

    The purpose of this study was to examine the utility of flexible and rigid endoscopy and stroboscopy for the identification of anatomical and physiological features in children with bilateral vocal fold lesions. The secondary purpose was to describe the age distribution of patients who could tolerate use of the different types of endoscopes. This cross-sectional clinic-based study included 38 children (ages 5 to 12 years) diagnosed with bilateral vocal fold lesions via videoendoscopy. Vocal fold vibratory characteristics (e.g., mucosal wave) were rated by 4 clinicians by consensus. Bilateral vocal fold lesions could be well described anatomically after visualization with both flexible and rigid endoscopes and were most commonly described as symmetrical and broad based. However, the clinicians' confidence in the accuracy of stroboscopy for rating vocal fold vibratory characteristics was limited for both flexible and rigid stroboscopes. Videoendoscopy was adequate for viewing and characterizing anatomical structures of bilateral vocal fold lesions in pediatric patients; however, vibratory characteristics were often not fully visualized with videostroboscopy. In view of the importance of visualizing vocal fold vibration in the differential diagnosis and treatment of vocal fold lesions, other imaging modalities, such as high-speed videoendoscopy, may provide more accurate descriptions of vocal fold vibratory characteristics in this population.

  2. Bilateral acute retinal necrosis associated with bilateral uveal effusion in an immunocompetent patient: A challenging association

    2018-01-01

    Full Text Available Bilateral uveal effusion syndrome associated with bilateral acute retinal necrosis is a diagnostic and therapeutic challenge. A 52 year old man presented with bilateral angle closure with choroidal detachment. With restricted fundus view, parenteral steroid was started. During close follow up bilateral discrete areas of peripheral retinitis were noted. Parenteral steroids were promptly stopped and parenteral antivirals with oral steroids were continued. It showed healing response with nil recurrences till last follow up. Aggressive treatment of bilateral uveal effusion with parenteral steroids can cause progression of bilateral acute retinal necrosis leading to phthisis bulbi. However early diagnosis, prompt intervention and close follow up are the key elements to therapeutic success even during diagnostic surprises and avoid costly mistakes.

    2014-03-01

    The widespread use of amiodarone is limited by its toxicity, notably to the optic nerve. We report two cases of bilateral optic nerve neuropathy due to amiodarone, and provide a detailed description of the disease. The first case was a 59-year-old man complaining from insidious monocular loss of vision within ten months of initiating amiodarone. Funduscopy and optical coherence tomography showed bilateral optic disc edema. The second case was a 72-year-old man presenting with a decrease in visual acuity in his left eye for a month. Funduscopy showed a left optic nerve edema, and fluorescein angiography showed bilateral papillitis. In both cases, the clinical presentation was not suggestive of ischemic neuropathy, because of the preservation of visual acuity and the insidious onset. In addition, both cardiovascular and inflammatory work-up were normal. An amiodarone-associated neuropathy was suspected, and amiodarone was discontinued with the approval of the cardiologist, with complete regression of the papilledema and a stabilization of visual symptoms. Differentiating between amiodarone-associated optic neuropathy and anterior ischemic optic neuropathy may be complicated by the cardiovascular background of such patients. The major criterion is the absence of a severe decrease in visual acuity; other criteria are the normality of cardiovascular and inflammatory work-up, and the improvement or the absence of worsening of symptoms after discontinuation of amiodarone. Amiodarone-associated neuropathy remains a diagnosis of exclusion, and requires amiodarone discontinuation, which can only be done with the approval of a cardiologist, and sometimes requires replacement therapy.

  10. Self generation, small generation, and embedded generation issues

    International Nuclear Information System (INIS)

    2001-01-01

    The New Brunswick Market Design Committee for electric power restructuring has been directed to examine issues regarding cogeneration and small-scale, on-site generation and how they will fit within the framework of the bilateral contract market. The Committee will also have to deal with issues of generation embedded in a distribution system. The Committee has defined cogeneration as the simultaneous production of electricity and useful thermal energy. Self-generation has been defined as small-scale power generation by an end-user, while embedded generation has been defined as a generation facility that is located within a distribution utility but is not directly connected to the transmission system. The Committee has postponed its decision on whether embedded generation will be eligible to participate under the bilateral contract market for electricity. This report discusses general issues such as the physical support of generation, market support of generation, transition issues and policy issues. It also discusses generation support issues such as operating reserves, transmission tariff issues, and distribution tariffs. Market support issues such as transmission access for generation sales were also considered, along with market access for generation sales, and net metering for behind the meter generation. 7 refs., 1 tab

    Wilms tumor (WT) with diffuse anaplasia has an unfavorable prognosis and is often (>70%) associated with mutations in the TP53 gene. Although most WTs are unilateral, 5-10% are bilateral, and they are almost always present with nephrogenic rests. The latter are considered a precursor of WT. Two cases of bilateral WTs with nephroblastomatosis, in which anaplastic changes were detected over a period of time, were analyzed using clinical, radiological, histopathological, and molecular-genetic data. TP53 was analyzed by direct sequencing of its full coding sequence and intron-exon boundaries in 11 fragments. DNA was extracted from paraffin-embedded or frozen specimens. High-resolution genomic copy number profiling was carried out by UCL Genomics on the Affymetrix Human Mapping 250K Nsp or Genome-Wide Human SNP Array 6.0 platform. Both cases demonstrated a strong association between the appearance of anaplastic clones and TP53 mutations. Synchronous ganglioneuroma was diagnosed in one case. Our cases are unique as they represent a long disease history and demonstrate the difficulties in managing rare cases of bilateral WT with anaplasia. These cases also emphasize the practical importance of modern molecular-genetic techniques and their clinical application. Moreover, they highlight the issue of the adequate sampling needed in order to gather comprehensive, efficient, and sufficient information about genetic events in a single tumor.

  12. Bilateral persistent hyperplastic primary vitreous

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available A case of bilateral persistent hyperplastic primary vitreous (PHPV in a 3-month-old male infant, who had bilateral leukokoria, is presented. The child was referred for imaging with a clinical suspicion of retinoblastoma. Gray-scale ultrasound evaluation revealed an echogenic band in the posterior segment of both globes, extending from the posterior surface of the lens capsule to the optic disc. Doppler examination revealed the presence of arterial flow in the band in both globes. Associated echogenic hemorrhage was also seen, which was confirmed by computed tomography. Most cases of PHPV are sporadic and unilateral, and bilateral PHPV is rare. The imaging features in this case suggest the diagnosis of bilateral PHPV and differentiate it from retinoblastoma. This entity, although infrequent, should be considered in the differential diagnosis while evaluating bilateral leukokoria.

    2011-01-01

    Background Globalisation has prompted countries to evaluate their position on trade in health services. However, this is often done from a multi-lateral, rather than a regional or bi-lateral perspective. In a previous review, we concluded that most of the issues raised could be better addressed from a bi-lateral relationship. We report here the results of a qualitative exercise to assess stakeholders' perceptions on the prospects for such a bi-lateral system, and its ability to address concerns associated with medical tourism. Methods 30 semi-structured interviews were carried out with stakeholders, 20 in India and 10 in the UK, to assess their views on the potential offered by a bi-lateral relationship on medical tourism between both countries. Issues discussed include data availability, origin of medical tourists, quality and continuity of care, regulation and litigation, barriers to medical tourism, policy changes needed, and prospects for such a bi-lateral relationship. Results The majority of stakeholders were concerned about the quality of health services patients would receive abroad, regulation and litigation procedures, lack of continuity of care, and the effect of such trade on the healthcare available to the local population in India. However, when considering trade from a bi-lateral point of view, there was disagreement on how these issues would apply. There was further disagreement on the importance of the Diaspora and the validity of the UK's 'rule' that patients should not fly more than three hours to obtain care. Although the opinion on the prospects for an India-UK bi-lateral relationship was varied, there was no consensus on what policy changes would be needed for such a relationship to take place. Conclusions Whilst the literature review previously carried out suggested that a bi-lateral relationship would be best-placed to address the concerns regarding medical tourism, there was scepticism from the analysis provided in this paper based on the

    2015-01-01

    BACKGROUND: Juvenile nasopharyngeal angiofibroma is a benign, vascular tumour that primarily occurs in adolescent males. Despite its benign nature, aggressive growth patterns can cause potential life-threatening complications. Juvenile nasopharyngeal angiofibroma is normally unilateral, originating...... from the sphenopalatine artery, but bilateral symptoms can occur if a large tumour extends to the contralateral side of the nasopharynx. This paper presents the first reported case of true bilateral extensive juvenile nasopharyngeal angiofibroma involving clinically challenging pre-surgical planning...... embolisation. Radical removal performed as one-step, computer-assisted functional endoscopic sinus surgery was performed. The follow-up period was uncomplicated. CONCLUSION: This case illustrates the importance of suspecting bilateral juvenile nasopharyngeal angiofibroma in patients presenting with bilateral...

  4. Acute Bilateral Superior Branch Vestibular Neuropathy

    2018-05-01

    Full Text Available The rapid onset of a bilateral vestibular hypofunction (BVH is often attributed to vestibular ototoxicity. However, without any prior exposure to ototoxins, the idiopathic form of BVH is most common. Although sequential bilateral vestibular neuritis (VN is described as a cause of BVH, clinical evidence for simultaneous and acute onset bilateral VN is unknown. We describe a patient with an acute onset of severe gait ataxia and oscillopsia with features compatible with acute BVH putatively due to a bilateral VN, which we serially evaluated with clinical and laboratory vestibular function testing over the course of 1 year. Initially, bilateral superior and horizontal semicircular canals and bilateral utricles were impaired, consistent with damage to both superior branches of each vestibular nerve. Hearing was spared. Only modest results were obtained following 6 months of vestibular rehabilitation. At a 1-year follow-up, only the utricular function of one side recovered. This case is the first evidence supporting an acute presentation of bilateral VN as a cause for BVH, which would not have been observed without critical assessment of each of the 10 vestibular end organs.

    PURPOSE: To evaluate outcome of patients with bilateral breast cancer as compared to unilateral breast cancer treated with breast conservation therapy. This is a complex issue, however, we address this by comparing (1) synchronous bilateral breast cancer patients, (2) metachronous bilateral breast cancer patients from the time of diagnosis of the second breast primary, and (3) unilateral breast cancer patients. The authors recognize that there are inherent biases in these comparisons. MATERIALS AND METHODS: A total of 60 bilateral patients and 1080 unilateral patients treated with breast conservation therapy from 1977-1994 were analyzed for outcome. Of the 60 bilateral patients, 44 were metachronous bilateral breast cancer patients (MBBC) and 16 were synchronous breast cancer patients (SBBC). Patients with bilateral breast cancer had local-regional disease with the following tumor stages: DCIS=8%, T1=80%, T2=12%, pathologic N0=90%, pathologic N+=10%. Unilateral patients had the following tumor stages: DCIS=10%, T1=66%, T2=20%, T3=1.2%, Tx=2%, pathological N0=80%, pathological N+=19%, and NX=1%. The majority of patients received lumpectomy and axillary node dissection followed by radiation therapy. The median size of the lesions were 1.4cm and 1.5cm for bilateral and unilateral patients, respectively. Median total dose to the primary tumor was 60Gy for both unilateral and bilateral patients. Of the 44 metachronous bilateral breast cancer patients, 14 patients received breast conservation for both the first and second lesions while 30 patients had breast conservation for only the second metachronous breast lesion. Thus 58 lesions in the 44 patients were treated with breast conservation therapy in the patients with metachronous bilateral breast cancer. Of the synchronous bilateral breast cancer patients, 13 out of 16 patients had breast conserving therapy for both breasts, and 3 patients received mastectomy for the second synchronous breast tumor. The median follow

    Recurrence of hypercortisolism in patients after bilateral adrenalectomy for Cushing disease is extremely rare. We present a 27-year-old man who previously underwent bilateral adrenalectomy for Cushing disease with complete clinical resolution. Cushingoid features recurred 12 years later, with bilateral testicular enlargement. Hormonal tests confirmed adrenocorticotropic hormone (ACTH)-dependent Cushing disease. Surgical resection of the testicular tumors led to clinical and biochemical remission. Gene expression analysis of the tumor tissue by quantitative polymerase chain reaction showed high expression of all key steroidogenic enzymes. Adrenocortical-specific genes were 5.1 × 105 (CYP11B1), 1.8 × 102 (CYP11B2), and 6.3 × 104 (MC2R) times higher than nonsteroidogenic fibroblast control. This correlated with urine steroid metabolome profiling showing 2 fivefold increases in the excretion of the metabolites of 11-deoxycortisol, 21-deoxycortisol, and total glucocorticoids. Leydig-specific genes were 4.3 × 101 (LHCGR) and 9.3 × 100 (HSD17B3) times higher than control, and urinary steroid profiling showed twofold increased excretion of the major androgen metabolites androsterone and etiocholanolone. These distinctly increased steroid metabolites were suppressed by dexamethasone but unresponsive to human chorionic gonadotropin stimulation, supporting the role of ACTH, but not luteinizing hormone, in regulating tumor-specific steroid excess. We report bilateral testicular tumors occurring in a patient with recurrent Cushing disease 12 years after bilateral adrenalectomy. Using mRNA expression analysis and steroid metabolome profiling, the tumors demonstrated both adrenocortical and gonadal steroidogenic properties, similar to testicular adrenal rest tumors found in patients with congenital adrenal hyperplasia, suggesting the presence of pluripotent cells even in patients without congenital adrenal hyperplasia.

  8. Description, prescription and the choice of discount rates

    International Nuclear Information System (INIS)

    Baum, Seth D.

    2009-01-01

    The choice of discount rates is a key issue in the analysis of long-term societal issues, in particular environmental issues such as climate change. Approaches to choosing discount rates are generally placed into two categories: the descriptive approach and the prescriptive approach. The descriptive approach is often justified on grounds that it uses a description of how society discounts instead of having analysts impose their own discounting views on society. This paper analyzes the common forms of the descriptive and prescriptive approaches and finds that, in contrast with customary thinking, both forms are equally descriptive and prescriptive. The prescriptions concern who has standing (i.e. who is included) in society, how the views of these individuals are measured, and how the measurements are aggregated. Such prescriptions are necessary to choose from among the many possible descriptions of how society discounts. The descriptions are the measurements made given a choice of measurement technique. Thus, the labels 'descriptive approach' and 'prescriptive approach' are deeply misleading, as analysts cannot avoid imposing their own views on society. (author)

    We report on a patient with a rare case of bilateral tension pneumothorax that occurred after acupuncture. A 69-year-old large-bodied man, who otherwise had no risk factors for spontaneous pneumothorax, presented with chest pressure, cold sweats and shortness of breath. Immediately after bilateral pneumothorax had been identified on a chest radiograph in the emergency room, his blood pressure and percutaneous oxygen saturation suddenly decreased to 78 mm Hg and 86%, respectively. We confirmed deterioration in his cardiopulmonary status and diagnosed bilateral tension pneumothorax. We punctured his chest bilaterally and inserted chest tubes for drainage. His vital signs promptly recovered. After the bilateral puncture and drainage, we learnt that he had been treated with acupuncture on his upper back. We finally diagnosed a bilateral tension pneumothorax based on the symptoms that appeared 8 h after the acupuncture. Because the patient had no risk factors for spontaneous pneumothorax, no alternative diagnosis was proposed. We recommend that patients receiving acupuncture around the chest wall must be adequately informed of the possibility of complications and expected symptoms, as a definitive diagnosis can be difficult without complete information.

    Juvenile nasopharyngeal angiofibroma is a benign, vascular tumour that primarily occurs in adolescent males. Despite its benign nature, aggressive growth patterns can cause potential life-threatening complications. Juvenile nasopharyngeal angiofibroma is normally unilateral, originating from the sphenopalatine artery, but bilateral symptoms can occur if a large tumour extends to the contralateral side of the nasopharynx. This paper presents the first reported case of true bilateral extensive juvenile nasopharyngeal angiofibroma involving clinically challenging pre-surgical planning and surgical strategy. A 21-year-old male presented with increasing bilateral nasal obstruction and discharge. Examination revealed tumours bilaterally and imaging demonstrated non-contiguous tumours. Pre-operative angiography showed strictly ipsilateral vascular supplies requiring bilateral embolisation. Radical removal performed as one-step, computer-assisted functional endoscopic sinus surgery was performed. The follow-up period was uncomplicated. This case illustrates the importance of suspecting bilateral juvenile nasopharyngeal angiofibroma in patients presenting with bilateral symptoms. Our management, including successful pre-operative planning, enabled one-step total removal of both tumours and rapid patient recovery.

    Full Text Available Laryngocele is an air-filled, abnormal dilation of the laryngeal saccule that extends upward within the false vocal fold, in communication with the laryngeal lumen. A case of 43-year-old male with bilateral internal laryngoceles, who has been treated as asthma for 4 years, is presented. The patient had dyspnea, cough, and excessive phlegm for a month and a late onset stridor. Flexible nasopharyngolaryngoscopy showed bilateral cystic enlargements of the false vocal folds and true vocal folds could not be visualized. Laryngeal CT without contrast enhancement showed bilateral internal laryngoceles. Submucosal total excision of bilateral cystic masses including parts of false vocal folds was performed. The symptoms resolved immediately after surgery. Although the incidence of internal laryngocele is rare, it should be remembered in the differential diagnosis of upper airway problems and diagnostic flexible nasopharnygolaryngoscopy is routinely indicated for airway evaluation in at-risk patients.

    adjust for relevant risk factors, the 90-day odds ratio (OR) of undergoing manipulation after simultaneous bilateral TKA was significantly lower than that for unilateral TKA (OR = 0.70; 95% confidence interval [CI], 0.57 to 0.86) and staged bilateral TKA (OR = 0.71; 95% CI, 0.57 to 0.90). Similarly, at 180 days, the odds of undergoing manipulation were significantly lower after simultaneous bilateral TKA than after both unilateral TKA (OR = 0.71; 95% CI, 0.59 to 0.84) and staged bilateral TKA (OR = 0.76; 95% CI, 0.63 to 0.93). The frequency of manipulation was significantly associated with younger age, fewer comorbidities, black race, and the absence of obesity. Although the ORs were small (close to 1), simultaneous bilateral TKA had a significantly decreased rate of stiffness requiring manipulation under anesthesia at 90 days and 180 days after knee replacement compared with that after staged bilateral TKA and unilateral TKA.

    Bilateral cochlear implants aim to provide hearing to both ears for children who are deaf and promote binaural/spatial hearing. Benefits are limited by mismatched devices and unilaterally-driven development which could compromise the normal integration of left and right ear input. We thus asked whether children hear a fused image (ie. 1 vs 2 sounds) from their bilateral implants and if this "binaural fusion" reduces listening effort. Binaural fusion was assessed by asking 25 deaf children with cochlear implants and 24 peers with normal hearing whether they heard one or two sounds when listening to bilaterally presented acoustic click-trains/electric pulses (250 Hz trains of 36 ms presented at 1 Hz). Reaction times and pupillary changes were recorded simultaneously to measure listening effort. Bilaterally implanted children heard one image of bilateral input less frequently than normal hearing peers, particularly when intensity levels on each side were balanced. Binaural fusion declined as brainstem asymmetries increased and age at implantation decreased. Children implanted later had access to acoustic input prior to implantation due to progressive deterioration of hearing. Increases in both pupil diameter and reaction time occurred as perception of binaural fusion decreased. Results indicate that, without binaural level cues, children have difficulty fusing input from their bilateral implants to perceive one sound which costs them increased listening effort. Brainstem asymmetries exacerbate this issue. By contrast, later implantation, reflecting longer access to bilateral acoustic hearing, may have supported development of auditory pathways underlying binaural fusion. Improved integration of bilateral cochlear implant signals for children is required to improve their binaural hearing.

    2006-10-01

    Full Text Available Abstract Background The most common causes of hemotympanum are therapeutic nasal packing, epistaxis, blood disorders and blunt trauma to the head. Hemotympanum is characterized as idiopathic, when it is detected in the presence of chronic otitis media. A rare case of spontaneous bilateral hemotympanum in a patient treated with anticoagulants is presented herein. Case presentation A 72-year-old male presented with acute deterioration of hearing. In the patient's medical history aortic valve replacement 1 year before presentation was reported. Since then he had been administered regularly coumarinic anticoagulants, with INR levels maintained between 3.4 and 4.0. Otoscopy revealed the presence of bilateral hemotympanum. The audiogram showed symmetrical moderately severe mixed hearing loss bilaterally, with the conductive component predominating. Tympanograms were flat bilaterally with absent acoustic reflexes. A computerized tomography scan showed the presence of fluid in the mastoid and middle ear bilaterally. Treatment was conservative and consisted of a 10-day course of antibiotics, anticongestants and temporary interruption of the anticoagulant therapy. After 3 weeks, normal tympanic membranes were found and hearing had returned to previous levels. Conclusion Anticoagulant intake should be included in the differential diagnosis of hemotympanum, because its detection and appropriate treatment may lead to resolution of the disorder.

  19. Medical tourism: a review of the literature and analysis of a role for bi-lateral trade.

    Science.gov (United States)

    Smith, Richard; Martínez Álvarez, Melisa; Chanda, Rupa

    2011-12-01

    With increasing globalization, many countries are considering opening their health systems to greater cross-border movement of patients. This is usually done from the viewpoint of a multi-lateral trade relationship. This paper considers the issues that arise from this debate from a bi-lateral perspective. A systematic literature review was carried out on 'Medical Tourism' from the perspective of a bi-lateral trade relationship, using the UK and India as a case study. There is a dearth of data and discussion on such bi-lateral trade. This limited evidence offers some suggestions. Exporting countries may benefit from medical tourism by generating foreign exchange and reversing the brain drain, but run the risk of creating a dual system, where the local population is crowded out. Importing countries can benefit from alleviating waiting lists and lowering healthcare costs, but may risk quality of care and legal liability. However, evidence from a bi-lateral perspective suggests that the positive aspects can be capitalised, and the negative ones reduced. The key recommendations from this paper are for more evidence to be collected at the country and international level, and for countries to consider trade in health services from a bi-lateral rather than multi-lateral perspective.

    Full Text Available We report the clinical findings of a patient with severe bilateral keratectasia 34 years after a penetrating keratoplasty (PK in both eyes. An otherwise healthy 67-year-old man complained of deterioration of the eyesight in both eyes over the last 6 months. The patient was diagnosed with bilateral keratoconus at the age of 32 years, and he underwent a bilateral PK. At presentation, visual acuity was 20/200 in the right eye and light perception in the left eye. A Pentacam pachymetric map revealed a central pachymetry of 720 µm in the right eye and of 710 µm in the left eye, as well as an average paracentral pachymetry of 436 and 270 µm in the 9-mm zone in the right and the left eye, respectively. Corneal topography revealed bilateral irregular and asymmetric bowing with generalized steepening and high corneal power. We describe a case of bilateral keratectasia 34 years after PK in a patient who was originally diagnosed with bilateral keratoconus.

    Juvenile nasopharyngeal angiofibroma (JNA) is the most common benign neoplasm of the nasopharynx. Almost always unilateral on diagnosis, JNAs are locally invasive and may extend across the midline, giving a false bilateral appearance; as such, true bilateral JNA is exceedingly rare. We present a recent case of true bilateral JNA. Single case report of a patient with bilateral JNA, including clinical presentation, diagnosis, and management. The patient presented with unilateral nasal obstruction and recurrent epistaxis. Computed tomography and magnetic resonance imaging demonstrated bilateral, noncontiguous masses. Angiography revealed independent vascular supplies from each respective side with no bilateral supply noted. The patient underwent preoperative embolization followed by endoscopic surgical removal of the larger mass; no complications were noted. Follow-up at 2 years demonstrated no recurrence or growth. The vast majority of JNAs are unilateral, though invasive growth to the contralateral side may appear "bilateral" in presentation. Proper identification of true bilateral JNA is helpful in guiding management, wherein excision of both tumors may not be necessary. © 2014 ARS-AAOA, LLC.

    2016-01-01

    The effective waste heat recovery is one of the present-day challenges in the industry and power engineering. The energy systems dedicated for waste heat conversion into electricity are usually characterized by low efficiency and are complicated in the design. The possibility of waste heat recovery via thermoelectric materials may be an interesting alternative to the currently used technologies. In particular, due to their material characteristics, conducting polymers may be competitive when compared with the power machinery and equipment. These materials can be used in a wide range of the geometries e.g. the bulk products, thin films, pristine form or composites and the others. In this article, the authors present selected issues related to the mathematical and thermodynamic description of the heat transfer processes in the thermoelectric materials dedicated for the waste heat recovery. The link of these models with electrical properties of the material and a material solution based on a conducting polymer have also been presented in this paper. (paper)

  10. Bilateral Facial Paralysis Caused by Bilateral Temporal Bone Fracture: A Case Report and a Literature Review

    Directory of Open Access Journals (Sweden)

    Sultan Şevik Eliçora

    2015-01-01

    Full Text Available Bilateral facial paralysis caused by bilateral temporal bone fracture is a rare clinical entity, with seven cases reported in the literature to date. In this paper, we describe a 40-year-old male patient with bilateral facial paralysis and hearing loss that developed after an occupational accident. On physical examination, House-Brackmann (HB facial paralysis of grade 6 was observed on the right side and HB grade 5 paralysis on the left. Upon temporal bone computed tomography (CT examination, a fracture line exhibiting transverse progression was observed in both petrous temporal bones. Our patient underwent transmastoid facial decompression surgery of the right ear. The patient refused a left-side operation. Such patients require extensive monitoring in intensive care units because the presence of multiple injuries means that facial functions are often very difficult to evaluate. Therefore, delays may ensue in both diagnosis and treatment of bilateral facial paralysis.

    We reported a case of cryptococcal meningitis presenting with bilateral optic neuropathy in an immunocompetent patient. A 64-year-old Malay gentleman with no medical comorbidities presented with acute bilateral blurring of vision for a week, which was associated with generalised throbbing headache and low grade fever. He also had som-nolence and altered consciousness. Visual acuity in both eyes was no perception of light with poor pupillary reflexes. Extraocular muscle movements were normal. Anterior segments were unremarkable bilaterally. Fundoscopy revealed bilateral optic disc swelling. CT scan of the brain showed multifocal infarct, but no meningeal enhancement or mass. Cerebrospinal fluid opening pressure was normal, while its culture grew Cryptococcus neoformans. A diagnosis of cryptococcal meningitis with bilateral optic neuropathy was made. Patient was treated with a six-week course of intravenous flu-conazole and started concomitantly on a fortnight's course of intravenous amphotericin B. After that, his general condition improved, but there was still no improvement in his visual acuity. On reviewing at two months post-initiation of treatment, fundi showed bilateral optic atrophy. Bilateral optic neuropathy secondary to cryptococcal meningitis was rare. The prognosis was guarded due to the sequelae of optic atrophy. Anti-fungal medication alone may not be sufficient to manage this condition. However, evidence for other treatment modalities is still lacking and further clinical studies are required.

    Full Text Available The bilateral filter plays a key role in image processing applications due to its intuitive parameterization and its high quality filter result, smoothing homogeneous regions while preserving the edges of the objects. Considering the image as a topological relief, seeing pixel intensities as peaks and valleys, we introduce a way to control the tonal weighting coefficients, the flowing bilateral filter, reducing "halo" artifacts typically produced by the regular bilateral filter around a large peak surrounded by two valleys of lower values. In this paper we propose to investigate exact and approximated versions of CPU and parallel GPU (Graphical Processing Unit based implementations of the regular and flowing bilateral filter using the NVidia CUDA API. Fast implementations of these filters are important for the processing of large 3D volumes up to several GB acquired by x-ray or electron tomography.

    The optimal treatment for bilateral hearing loss continues to evolve as cochlear implant (CI) and hearing aid technologies advance, as does our understanding of the central auditory system. Ongoing discussions continue on the validity and feasibility of bilateral CI in terms of performance, justification of need, medical/surgical safety concerns, and economics. The purpose of this review article is to provide an update on the advantages and disadvantages of bilateral CI and to provide a discussion on timing (simultaneous vs. sequential), technology (bimodal vs. binaural) and feasibility. Binaural advantages are found in both adult and pediatric bilateral CI recipients, the greatest being the head shadow effect and improvements in localization and loudness summation. This theoretically offers an advantage over their unilateral implanted counterparts in terms of improved sound localization and enhanced speech perception under noisy conditions. Most investigators agree that bilateral stimulation during critical periods of development is paramount for optimizing auditory functioning in children. Currently, bilateral CI is widely accepted as a safe and effective means of bilateral auditory stimulation.

    Full Text Available Introduction: Ectopia lentis is defined as a crystalline lens displacement, either partially or completely, due to zonular abnormalities. It can be a result of trauma, hereditary ocular disease, or part of systemic diseases, like Marfan syndrome and homocystinuria.Case description: We report a case of a medically free 16-year-old girl, who was referred to our hospital complaining of poor vision and a squint in both eyes since childhood. Her history included a traffic accident when she was one-year-old. She was previously diagnosed with alternating esotropia, which was treated with glasses, alternating patching, and bilateral Botox injections. On examination, she had a visual acuity of 6/7.5 with correction in the right eye and 6/6 with correction in the left eye. She had an esotropia of 60 prism diopters, which was partially corrected to 40 prism diopters for near and distance vision. Fundus examination showed myopic changes in each eye and dislocated lenses in the posterior pole at 6 o’clock. Our case was stable, so we used conservative management with contact lenses.Conclusion: Bilateral posterior lens dislocation is very rare. A proper examination is important and early diagnosis can prevent serious complications, such as retinal detachment or pupillary block glaucoma.

    Full Text Available We report a rare case of bilateral keratoconus in association with achondroplasia. A 26-year-old male, with a known case of achondroplasia, complained of bilateral gradual deterioration in vision for the past few years. Slit lamp biomicroscopy showed bilateral central corneal protrusion and stromal thinning at the apex consistent with keratoconus. a trial of hard contact lens fitting failed to improve VA in the left eye (LE. Right eye (RE improved to 20/25. The patient underwent penetrating keratoplasty (PKP in his LE. Twenty-seven months postoperatively, uncorrected visual acuity (UCVA was 20/30. Ophthalmologists should be aware that patients with achondroplasia who complain of poor vision should be suspected of having keratoconus once other more common conditions are ruled out.

  18. Control issues related to bilateral teleoperation of long-reach, flexible manipulators

    A challenging problem presently being addressed by the Department of Energy (DOE) is the extraction of large volumes of hazardous waste from underground waste storage facilities. The nature of the material requires the use of robotic and teleoperated systems. Furthermore, the constraints of the storage tanks require the use of long reach manipulators. These robots are characterized by their large workspace and reduced mass. Unfortunately, this reduction in mass increases structural compliance, making these robots susceptible to vibration. Until recently, no attempt has been made to provide the operator any type of force reflection due to the compliance of the slave robot. This paper addresses the control of bilateral teleoperation systems that use long-reach, flexible manipulators. Analysis and experiments show that the compliance of the slave robot directly affects the stability of the teleoperation system. This study suggests that this may be controlled by increasing the damping on the master robot. However, this increase in target damping increases the energy an operator must exert during the execution of a task. A new teleoperation strategy adapts the target impedance of the master robot to variations in the identified impedance of the remote environment coupled to the slave robot. Experiments show increased performance due to a decrease in the energy the operator must provide during task execution

    Full Text Available Complex regional syndrome type 1 (CRPS-1 is a painful clinical condition. It occurs after a painful event and characterized by allodynia, hyperalgesia, edema, abnormalities in skin blood flow and abnormal sudomotor activity. When CRPS-1 is associated with nerve injury, it is defined as CRPS-2. Central and peripheral theory are responsible in etiopathogenesis of CRPS-1. Generally it occurs in the injured limb. But, it may ocur in the opposite extremities. In this article, we present a case developing bilateral CRPS-1 after bilateral tibia and fibula fracture by reviewing current literatüre.

    Acupuncture is an ancient complementary medicine which is currently used worldwide. Many serious adverse events have been reported which include a spectrum of mild-to-fatal complications. However, the level of awareness with regard to complications is still low both to physicians and patients. We report a 63-year-old who presented with acute shortness of breath 2 hours after having had acupuncture. On examination, there was absent breath sound heard on the left lung and slightly reduced breath sound on the right lung. She had type 1 respiratory failure. Urgent chest radiograph confirmed bilateral pneumothorax which was more severe on the left with tension pneumothorax and mediastinal shift. Chest tubes were inserted bilaterally after failed needle aspiration attempts. Subsequently, the pneumothoraces resolved, and she was discharged well. The bilateral pneumothoraces caused by acupuncture were curable but could have been potentially fatal if diagnosis was delayed. This case report adds to the limited current literature on the complications of acupuncture leading to bilateral pneumothoraces. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

    There is an ongoing global discussion on whether or not bilateral cochlear implantation should be standard care for bilateral deafness. Contrary to unilateral cochlear implantation, however, little is known about the effect of bilateral cochlear implantation on tinnitus. To investigate tinnitus outcomes 1 year after bilateral cochlear implantation. Secondarily, to compare tinnitus outcomes between simultaneous and sequential bilateral cochlear implantation and to investigate long-term follow-up (3 years). This study is a secondary analysis as part of a multicenter randomized controlled trial. Thirty-eight postlingually deafened adults were included in the original trial, in which the presence of tinnitus was not an inclusion criterion. All participants received cochlear implants (CIs) because of profound hearing loss. Nineteen participants received bilateral CIs simultaneously and 19 participants received bilateral CIs sequentially with an inter-implant interval of 2 years. The prevalence and severity of tinnitus before and after simultaneous and sequential bilateral cochlear implantation were measured preoperatively and each year after implantation with the Tinnitus Handicap Inventory (THI) and Tinnitus Questionnaire (TQ). The prevalence of preoperative tinnitus was 42% (16/38). One year after bilateral implantation, there was a median difference of -8 (inter-quartile range (IQR): -28 to 4) in THI score and -9 (IQR: -17 to -9) in TQ score in the participants with preoperative tinnitus. Induction of tinnitus occurred in five participants, all in the simultaneous group, in the year after bilateral implantation. Although the preoperative and also the postoperative median THI and TQ scores were higher in the simultaneous group, the median difference scores were equal in both groups. In the simultaneous group, tinnitus scores fluctuated in the 3 years after implantation. In the sequential group, four patients had an additional benefit of the second CI: a total

    Concerning a hydraulic bilateral construction robot, its system constitution, structures and functions of important components, and the results of some tests are explained, and the researches conducted at Gifu University are described. The construction robot in this report is a servo controlled system of a version developed from the mini-shovel now available in the market. It is equipped, in addition to an electrohydraulic servo control system, with various sensors for detecting the robot attitude, vibration, and load state, and with a camera for visualizing the surrounding landscape. It is also provided with a bilateral joy stick which is a remote control actuator capable of working sensation feedback and with a rocking unit that creates robot movements of rolling, pitching, and heaving. The construction robot discussed here, with output increased and response faster thanks to the employment of a hydraulic driving system for the aim of building a robot system superior in performance to the conventional model designed primarily for heavy duty, proves after tests to be a highly sophisticated remotely controlled robot control system.

    Full Text Available OBJECTIVE: To evaluate the efficacy and safety of bilateral pallidotomies in five patients with generalized dystonia. BACKGROUND: Generalized dystonias are frequently a therapeutic challenge, with poor responses to pharmacological treatment. GPi (globus pallidus internus pallidotomies for Parkinson's disease ameliorate all kinds of dyskinesias/dystonia, and recent studies reported a marked improvement of refractory dystonias with this procedure. METHODS: Five patients with generalized dystonias refractory to medical treatment were selected; one posttraumatic and four idiopathic. The decision to perform bilateral procedures was based on the predominant axial involvement in these patients. Dystonia severity was assessed with the Burke-Fahn-Marsden Dystonia Scale (BFM. Simultaneous procedures were performed in all but one patient, who had a staged procedure. They were reevaluated with the same scale (BFM by an unblinded rater at 1, 2, 3, 30, 60, 90, 120 and 180 days post-operatively. RESULTS: The four patients with idiopathic dystonia showed a progressive improvement up to three months; the patient with posttraumatic dystonia relapsed at three months. One patient had a marked improvement, being able to discontinue all the medications. A mean decrease in the BFM scores of 52,58% was noted. One patient had a trans-operative motor seizure followed by a transient hemiparesis secondary to rack hemorrhage; other was lethargic up to three days after the procedure. CONCLUSIONS: Our results show that bilateral GPi pallidotomies may be a safe and effective approach to medically refractory generalized dystonias; it can also be speculated that the posttraumatic subgroup may not benefit with this procedure.As distonias generalizadas são freqüentemente um desafio terapêutico, com pobres respostas aos tratamentos farmacológicos.

    Bilateral simultaneous elbow dislocations are extremely rare and have only been described in 12 cases. In the paediatric population unilateral elbow dislocations are rare with 3–6% of all elbow injuries and there are only few studies describing this injury exclusively in children. There is only one case report of a paediatric patient who sustained a simultaneous bilateral elbow dislocation with medial epicondyle fractures. We present a second paediatric case of simultaneous bilateral elbow dislocation with associated displaced bilateral medial epicondyle fractures in a gymnast with joint hyperlaxity (3 of 5 Wynne-Davies criteria) treated with closed reduction and short-term immobilisation (3 weeks). The patient returned to full trampoline gymnastics between 4 and 5 months postinjury and made an uneventful recovery. PMID:23234820

    Full Text Available The EU is a world economic power and a major trading partner for most countries. All the time, this region has been interested and has acted towards a free and fair trade. The decrease and even the elimination of tariff and non-tariff barriers in the world trade are among the main objectives of the EU strategy for international trade. At the moment, the elusive outcome of the WTO Doha Round has led to the proliferation of bilateral trade agreements worldwide. Although the EU remains committed to further development of the multilateral trading system, however, the EU still has appealed also to the development of bilateral trade relations. The aim of this paper is to illustrate the current bilateral dimension of the common commercial policy of the EU. In conclusion, to describe this bilateral approach of the EU we are using one word, namely “diversity”.

    Full Text Available Bilateral tubal pregnancy is very rare and occurs in only 1 out of every 200,000 spontaneous pregnancies. In this case, a 29-year-old woman with a history of primary infertility underwent treatment with human menopausal gonadotropin (hMG-human chorionic gonadotropin (hCG, and became pregnant. A gestational sac (GS was not detected in the uterus and transvaginal ultrasonography (USG revealed GS with fetal heartbeat in the left adnexa at 7 weeks and 6 days of gestation. The patient underwent laparoscopic surgery and ultimately, bilateral tubal pregnancy was diagnosed. Consequently, bilateral fallopian tube resection was performed. Afterwards, she conceived by assisted reproductive technology (ART and delivered vaginally. This case suggests that even if a GS is found in one fallopian tube by USG, it is important to evaluate the other fallopian tube carefully.

    There is a paucity of epidemiologic information about the eye malformations anophthalmia and microphthalmia. Using data from a large population-based registry, we explored prevalences and maternal/infant characteristics associated with anophthalmia and bilateral microphthalmia. Data were derived from the California Birth Defects Monitoring Program, a population-based active surveillance system for collecting information on infants and fetuses with congenital malformations using multiple source ascertainment. Approximately 2.5 million births (liveborn and stillborn) occurred during the ascertainment period, 1989-1997. Information on maternal and infant/fetal characteristics was obtained from California birth certificate and fetal death files. The prevalence per 10,000 livebirths and stillbirths for anophthalmia was 0.18 and for bilateral microphthalmia was 0.22. These estimates reflect prevalences among births without chromosomal anomalies. Relative risks of anophthalmia were modestly higher among women aged 40 or more (relative risk = 2.0, 95% confidence interval 0.5-8.6). Risks were substantially lower for those mothers with >12 years of education, even after adjusting for other study factors, relative risk = 0.6 (0.2-1.7). The risk of anophthalmia was approximately twofold among multiple births compared to singletons. Similar to results for anophthalmia, decreased risks for bilateral microphthalmia were observed for maternal education of 12 years or more and increased risks observed for multiple births. These data show descriptive epidemiologic features of anophthalmia and bilateral microphthalmia. Copyright 2005 Wiley-Liss, Inc.

Um sinal chave para o diagnóstico foi a evidência de respiração paradoxal com o doente em decúbito supino. Havia piora da oxigenação e da capacidade vital forçada com a mudança da posição ortostática para supina. A fluoroscopia ortostática foi normal. A pressão inspiratória máxima estava muito reduzida. A estimulação elétrica transcutânea do diafragma foi normal, e a eletroestimulação do nervo frênico mostrou ausência de resposta, permitindo o diagnóstico de paresia bilateral do diafragma.We report the case of a patient with severe dyspnea upon reclining. Lung disease, neuromuscular disorders and heart disease were ruled out. However, during the course of the investigation, bilateral diaphragmatic paresis was discovered. A key sign leading to the diagnosis was evidence of paradoxical respiration in the dorsal decubitus position. When the patient was moved from the orthostatic position to the dorsal decubitus position, oxygenation and forced vital capacity worsened. The orthostatic fluoroscopy was normal. Maximal inspiratory pressure was severely reduced. The responses to transcutaneous electric stimulation of the diaphragm were normal. However, electric stimulation of the phrenic nerve produced no response, leading to the diagnosis of bilateral diaphragmatic paresis.

    Meng Li

    Full Text Available OBJECTIVE: To evaluate the feasibility, effectiveness, and safety of reinnervation of the bilateral posterior cricoarytenoid (PCA muscles using the left phrenic nerve in patients with bilateral vocal fold paralysis. METHODS: Forty-four patients with bilateral vocal fold paralysis who underwent reinnervation of the bilateral PCA muscles using the left phrenic nerve were enrolled in this study. Videostroboscopy, perceptual evaluation, acoustic analysis, maximum phonation time, pulmonary function testing, and laryngeal electromyography were performed preoperatively and postoperatively. Patients were followed-up for at least 1 year after surgery. RESULTS: Videostroboscopy showed that within 1 year after reinnervation, abductive movement could be observed in the left vocal folds of 87% of patients and the right vocal folds of 72% of patients. Abductive excursion on the left side was significantly larger than that on the right side (P 0.05. No patients developed immediate dyspnea after surgery, and the pulmonary function parameters recovered to normal reference value levels within 1 year. Postoperative laryngeal electromyography confirmed successful reinnervation of the bilateral PCA muscles. Eighty-seven percent of patients in this series were decannulated and did not show obvious dyspnea after physical activity. Those who were decannulated after subsequent arytenoidectomy were not included in calculating the success rate of decannulation. CONCLUSIONS: Reinnervation of the bilateral PCA muscles using the left phrenic nerve can restore inspiratory vocal fold abduction to a physiologically satisfactory extent while preserving phonatory function at the preoperative level without evident morbidity.

    The aim of this article is to report the MRI features of bilateral parotid haemangiomas of infancy and highlight the diagnostic and prognostic value of MRI especially with regard to those lesions that may cause respiratory compromise. Retrospective review of MRI scans in six infants with bilateral parotid haemangiomas. The bilateral haemangiomas were symmetrical in all but one patient. On T1-weighted images the masses were isointense to muscle and on T2 they were hyperintense with numerous small vessels giving a septated appearance. There was vivid enhancement with gadolinium in all cases. In three patients, deep bilateral extensions were demonstrated involving the parapharyngeal spaces resulting in respiratory compromise which required tracheostomy. Bilateral parotid haemangiomas are rare, but when present may have deep extensions, which can result in respiratory compromise requiring tracheostomy. (orig.)

    The aim of this article is to report the MRI features of bilateral parotid haemangiomas of infancy and highlight the diagnostic and prognostic value of MRI especially with regard to those lesions that may cause respiratory compromise. Retrospective review of MRI scans in six infants with bilateral parotid haemangiomas. The bilateral haemangiomas were symmetrical in all but one patient. On T1-weighted images the masses were isointense to muscle and on T2 they were hyperintense with numerous small vessels giving a septated appearance. There was vivid enhancement with gadolinium in all cases. In three patients, deep bilateral extensions were demonstrated involving the parapharyngeal spaces resulting in respiratory compromise which required tracheostomy. Bilateral parotid haemangiomas are rare, but when present may have deep extensions, which can result in respiratory compromise requiring tracheostomy. (orig.)

    In Brazil electricity is traded through three segments: the spot market that balances offer and demand, with prices calculated by a cost-based computational model; the regulated market , where prices are settled in public auctions, and the free market for bilateral contracts. As spot and regulated market prices are public information, a seller is able to calculate his opportunity price to trade a bilateral contract in the free market by using the non-arbitrage principle. Thus, the seller searches the price of a bilateral contract in the free market that balances his/her revenues with the value expected in case it were negotiated in the regulated and the spot market. Besides the expected revenue, the seller may also consider the CVaR to measure the risk of her/his bilateral contract in the free market. So this paper develops a binomial lattice approach to price bilateral contracts in the free market, considering the seller's opportunity of negotiations in both regulated and spot markets, and measuring the contract risk directly.

    Full Text Available Purpose: The purpose of this study was to document clinical findings and management of a patient with bilateral globe luxation and optic nerve transection. Materials and Methods: A 25-year-old female patient was admitted to the emergency department with bilateral traumatic globe luxation following a motor vehicle accident. Results: Visual acuity testing showed no light perception. The right pupil was dilated and bilaterally did not react to light. The globes were bilaterally intact. A computed tomography scan revealed Le Fort type II fractures, bilateral optic nerve transection and disruption of all extraocular muscles. The globes of the patient were bilaterally reduced into the orbit. However, the patient developed phthisis bulbi in the right eye at month 3. Conclusion: Globe luxation presents a dramatic clinical picture, and may lead to the development of severe complications due to the concomitance of complete optic nerve dissection and multiple traumas. Even if the luxated globe is repositioned into the orbit, there is still an increased risk of the development of phthisis due to ischemia.

    Full Text Available Background. The risk of ovarian cancer is increased in the association of ovarian tumor, ascites, and hydrothorax with the significant elevated tumor marker CA-125. However, this association can be observed in a rare clinical and benign pathological entity, that is Demons-Meigs’ syndrome. Objective. To describe a rare case of Demons-Meigs' syndrome observed in our department. Methods. A black African woman of 35 years old, seventh gravida and fourth parous, underwent a total abdominal hysterectomy with bilateral salpingoophorectomy for large bilateral ovarian masses associated with significant ascites, bilateral pleural effusion, and particular highly elevated tumor marker CA-125 (1835 UI/mL in a pronounced general alteration condition. Results. The postoperative course was uneventful characterized by a complete remission of hydrothorax and ascites with normal level of CA-125 three months after tumor excision. Histology of both masses revealed a bilateral ovarian fibrothecoma, a benign tumor of the ovary, thus confirming the diagnosis of Demons-Meigs’ syndrome. Conclusion. The Demons-Meigs syndrome, although it strongly mimics the clinical picture of malignant metastatic ovarian cancer, remains a disease with benign prognosis after surgical tumor resection. This is a rare condition that must be known and recognized by practitioners to avoid unnecessary practices.

    Full Text Available Spontaneous bilateral ectopic gestation is very rare. The authors report a case diagnosed and taken care of at Yalgado Ouedraogo Teaching Hospital, Ouagadougou. It was a 30-year-old patient with no known pathological history. She had presented at the obstetric emergencies with a state of hypovolemic shock by haemoperitoneum with digestive disorders, pelvic pain, vaginal bleeding, and a mention of delayed menstruation. The ultrasound coupled with the urinary immunological pregnancy test confirmed the diagnosis of ruptured ectopic pregnancy and a bilateral form was suspected. A laparotomy in emergency confirmed the diagnosis of bilateral ectopic gestation with a right ampullary unruptured pregnancy and a left isthmic ruptured gestation. A bilateral salpingectomy was performed and counseling was made for the use of medical help of procreation in case of future need of pregnancy.

    Full Text Available Wernekink commissure syndrome secondary to caudal paramedian midbrain infarction (CPMI is a rare midbrain syndrome involving the decussation of the superior cerebellar peduncle in the caudal paramedian midbrain tegmentum. The central characteristics are constant bilateral cerebellar dysfunction, variable eye movement disorders, and rare delayed palatal myoclonus. Following is a description of the case of a 60-year-old man who presented with dizziness, slurred speech, and difficulty walking. Neurological examination revealed bilateral cerebellar dysfunction and bilateral internuclear ophthalmoplegia (bilateral INO. Serial magnetic resonance imaging (MRI revealed a lesion in the caudal paramedian midbrain with a “heart-shaped” sign on fluid-attenuation inversion recovery images and a “V-shaped” appearance on diffusion-weighted imaging (DWI. An acute CPMI with a “heart or V” appearance sign was diagnosed. Upon follow-up evaluation 3 months later, a palatal tremor accompanied by involuntary head tremor was discovered. Hypertrophy and increased signal of the bilateral inferior olivary nucleus, compatible with hypertropic olivary degeneration (HOD were revealed during a subsequent MRI study.

    Bilateral torticollis is a very rare form of a well known deformity i.e. muscular torticollis. This malformation might present a differential diagnostic problem both for orthopaedic surgeons and ophthalmologists, as well as, for neurologists. In agreement with the literature, the role of an injury during labour or defective embriogenesis is suggested to play a part.

    Full Text Available We reported a case of cryptococcal meningitis presenting with bilateral optic neuropathy in an immunocompetent patient. A 64-year-old Malay gentleman with no medical comorbidities presented with acute bilateral blurring of vision for a week, which was associated with generalised throbbing headache and low grade fever. He also had somnolence and altered consciousness. Visual acuity in both eyes was no perception of light with poor pupillary reflexes. Extraocular muscle movements were normal. Anterior segments were unremarkable bilaterally. Fundoscopy revealed bilateral optic disc swelling. CT scan of the brain showed multifocal infarct, but no meningeal enhancement or mass. Cerebrospinal fluid opening pressure was normal, while its culture grew Cryptococcus neoformans. A diagnosis of cryptococcal meningitis with bilateral optic neuropathy was made. Patient was treated with a six-week course of intravenous fluconazole and started concomitantly on a fortnight's course of intravenous amphotericin B. After that, his general condition improved, but there was still no improvement in his visual acuity. On reviewing at two months post-initiation of treatment, fundi showed bilateral optic atrophy. Bilateral optic neuropathy secondary to cryptococcal meningitis was rare. The prognosis was guarded due to the sequelae of optic atrophy. Anti-fungal medication alone may not be sufficient to manage this condition. However, evidence for other treatment modalities is still lacking and further clinical studies are required.

    2016-01-01

    Full Text Available Transient osteoporosis of the hip (TOH is a rare disorder characterized by acute severe coxalgia and temporary osteopenia in the proximal femur. Although most cases were unilateral or staged bilateral TOH, some authors reported that the pregnant patients simultaneously had TOH in their bilateral hips. However, there has been no report of simultaneous bilateral TOH in the patient without pregnancy. A 25-year-old Japanese woman without pregnancy had acute simultaneous bilateral hip pain. Plain X-ray of the bilateral hips did not show a periarticular osteopenia. However, magnetic resonance image obtained one week after the onset demonstrated increased T2-weighted signal intensity and decreased T1-weighted signal intensity in the bilateral femoral heads. She was treated conservatively, and follow-up magnetic resonance image at seven weeks after the onset returned to normal bone marrow signal intensity. Her bilateral coxalgia subsided gradually. At one year after the onset, she had no sign of symptomatic flair. Our experience with this case indicates that recognizing the possibility of simultaneous bilateral TOH is important unless the patient is pregnant, and magnetic resonance image is predictable test to make a diagnosis of TOH, even in the absence of abnormal finding on plain X-ray.

    Twenty children with bilateral Wilms' tumor were presented to the Children's Hospital Medical Center and Children's Cancer Research Foundation, Sidney Farber Cancer Institute, and Joint Center for Radiation Therapy (CHMC-CCRF, SFCI, JCRT) from January 1, 1956 to December 31, 1976. Of these 20, 16 had simultaneous and 4 had metachronous disease on presentation. All patients were treated with surgery, radiation and chemotherapy. Of the 16 patients with simultaneous disease, 10 (63%) are alive and free of disease 12+ to 175+ months post diagnosis and treatment, with median follow-up of 121 months. There were no long-term survivors in the metachronous group; all were dead of disease within 21 months from initial presentation of original tumor. With these data we relate prognosis to extent of disease and discuss a general approach to the management of bilateral Wilms' tumor

    Full Text Available Bilateral acute iris transillumination (BAIT is a recently defined disease characterized with bilateral acute, severe pigment dispersion of iris and pupil sphincter paralysis. The etiopathogenesis of the disease is unknown, but antibiotics such as moxifloxacin, clarithromycin, viral infections, and fumigation therapies were considered as probable etiologic factors. A 33-year-old female was referred to our clinic for acute iridocyclitis refractory to azathioprine, colchicum and corticosteroid treatments. Ophthalmic examination revealed bilateral pigment dispersion, significant iris transillumination, heavy pigment deposition in iridocorneal angle, and elevated intraocular pressure. Upon systemic evaluation she was found to have bacterial urinary tract infection. BAIT is an important cause of pigment dispersion and clinicians must be vigilant for this condition to avoid unnecessary diagnostic tests and treatment.

    2012-01-01

    Deep brain stimulation (DBS) of the subthalamic nucleus improves the motor symptoms of Parkinson's disease, but may produce a worsening of speech and language performance at rates and amplitudes typically selected in clinical practice. The possibility that these dissociated effects might be modulated by selective stimulation of left and right STN has never been systematically investigated. To address this issue, we analyzed motor, speech and language functions of 12 patients implanted with bilateral stimulators configured for optimal motor responses. Behavioral responses were quantified under four stimulator conditions: bilateral DBS, right-only DBS, left-only DBS and no DBS. Under bilateral and left-only DBS conditions, our results exhibited a significant improvement in motor symptoms but worsening of speech and language. These findings contribute to the growing body of literature demonstrating that bilateral STN DBS compromises speech and language function and suggests that these negative effects may be principally due to left-sided stimulation. These findings may have practical clinical consequences, suggesting that clinicians might optimize motor, speech and language functions by carefully adjusting left- and right-sided stimulation parameters.

    In evaluating patients sustaining bilateral isolated internal orbital fractures, the authors have observed both similar fracture locations and also similar expansion of orbital volumes. In this study, we aim to investigate if there is a propensity for the 2 orbits to fracture in symmetrically similar patterns when sustaining similar trauma. A retrospective chart review was performed studying all cases at our institution of bilateral isolated internal orbital fractures involving the medial wall and/or the floor at the time of presentation. The similarity of the bilateral fracture locations was evaluated using the Fisher's exact test. The bilateral expanded orbital volumes were analyzed using the Wilcoxon signed-rank test to assess for orbital volume similarity. Twenty-four patients with bilateral internal orbital fractures were analyzed for fracture location similarity. Seventeen patients (70.8%) had 100% concordance in the orbital subregion fractured, and the association between the right and the left orbital fracture subregion locations was statistically significant (P < 0.0001). Fifteen patients were analyzed for orbital volume similarity. The average orbital cavity volume was 31.2 ± 3.8 cm on the right and 32.0 ± 3.7 cm on the left. There was a statistically significant difference between right and left orbital cavity volumes (P = 0.0026). The data from this study suggest that an individual who suffers isolated bilateral internal orbital fractures has a statistically significant similarity in the location of their orbital fractures. However, there does not appear to be statistically significant similarity in the expansion of the orbital volumes in these patients.

    Managing HIV treatment is a complex multi-dimensional task because of a combination of factors such as stigma and discrimination of some populations who frequently get infected with HIV. In addition, patient-provider encounters have become increasingly multicultural, making effective communication and provision of ethically sound care a challenge. This article explores ethical issues that health service providers in the United States and Botswana encountered in their interaction with patients in HIV care. A descriptive qualitative design was used to collect data from health service providers and patients using focused group discussions. This article is based on responses from health service providers only. Participants and context: This article is based on 11 focused group discussions with a total sample of 71 service providers in seven US sites and one Botswana site. Ethical considerations: Ethical review boards at all the study sites reviewed the study protocol and approved it. Ethical review boards of the study's coordinating centers, Rutgers University and the University of California at San Francisco, also approved it. The study participants provided a written informed consent to participate. HIV service providers encountered ethical challenges in all the four Beauchamp and Childress' biomedical ethics of respect for patients' autonomy, beneficence, justice, and nonmaleficence. The finding that HIV service providers encounter ethical challenges in their interaction with patients is supported by prior studies. The ethical challenges are particularly prominent in multicultural care and resource-constrained care environments. Provision of HIV care is fraught with ethical challenges that tend to pose different issues depending on a given care environment. It is important that strong partnerships are developed among key stakeholders in HIV care. In addition, health service providers need to be provided with resources so they can provide quality and ethically sound

    2009-01-01

    Fibromuscular dysplasia (FMD) describes a group of conditions which cause nonatheromatous arterial stenoses, most commonly of the renal and carotid arteries, typically in young women. We report a rare case of bilateral segmental renal infarction secondary to FMD in a young male patient. His initial presentation with loin pain and pyrexia resulted in a delay in the definitive diagnosis of FMD. He was successfully treated with bilateral balloon angioplasty. The delayed diagnosis in this patient until the condition had progressed to bilateral renal infarcts highlights the need for prompt investigation and diagnosis of suspected cases of FMD.

    2017-12-01

    This study introduces a noise reduction technique that uses a complex bilateral filter. A bilateral filter is a nonlinear filter originally developed for images that can reduce noise while preserving edge information. It is an attractive filter and has been used in many applications in image processing. When it is applied to an acoustical signal, small-amplitude noise is reduced while the speech signal is preserved. However, a bilateral filter cannot handle noise with relatively large amplitudes owing to its innate characteristics. In this study, the noisy signal is transformed into the time-frequency domain and the filter is improved to handle complex spectra. The high-amplitude noise is reduced in the time-frequency domain via the proposed filter. The features and the potential of the proposed filter are also confirmed through experiments.

    Currently, no consistent evidence-based guidelines for the management of synchronous bilateral breast cancer (SBBC) exist and it is uncertain how presenting with SBBC affects patients' prognosis. We conducted a review of studies analyzing the association between SBBC and prognosis. The studies...... that reported adjusted effect measures were included in meta-analyses of effect of bilaterality on breast cancer mortality. From 57 initially identified records 17 studies from 11 different countries including 8,050 SBBC patients were included. The quality of the studies varied but was generally low with small...... sample sizes, and lack of consistent, detailed histo-pathological information. When doing meta-analysis on the subgroup of studies that provided adjusted effect estimates on breast cancer mortality (nine studies including 3,631 SBBC cases), we found that bilaterality in itself had a negative impact...

    Bilateral medial medullary infarction (MMI) is a rare stroke subtype. Here, we report a case with bilateral MMI caused by nondominant vertebral artery occlusion confirmed by brain digital subtraction angiography and magnetic resonance imaging basi-parallel-anatomical-scanning. We highlight that anterior spinal arteries could originate from a unilateral vertebral artery (VA). Radiologists and neurologists should pay attention to the nondominant VA as bilateral MMI may be induced by occlusion of nondominant VA that supplies the bilateral anteromedial territories of the medulla.

    Full Text Available We present a case study of a person (63 year-old man, who has been using statins for 18 years, with rhabdomyolysis of the bilateral adductor muscles associated with strenuous and prolonged eccentric exercises (hiking in a hot environment. Clinical examination showed predominantly on the right side muscle swelling and palpational pain of the bilateral adductor muscle groups and bilateral tibial edema. His serum creatine kinase (CK level was 12218 IU/L. T2-weighted magnetic resonance (MR images showed a high signal intensity in the bilateral adductor muscles of the hip. The patient did not develop complications and returned to his previous performance level in 30 days following adequate hydration and resting of the affected muscles. Strenuous eccentric exercise should be avoided during the course of statin use and clinicians should be aware of present observations when considering the significance of acute CK elevations in patients on statin treatment

    Nasolabial cysts are rare, nonodontogenic, soft-tissue, developmental cysts occurring inferior to the nasal alar region. They are thought to arise from remnants of the nasolacrimal ducts and they are frequently asymptomatic. We report a rare case of bilateral nasolabial cysts accompanied by bilateral chronic dacryocystitis. A 48-year-old woman suffering from bilateral chronic dacryocystitis was referred to our department for endonasal dacryocystorhinostomy. She had undergone external dacryocystorhinostomy on the left side a few years earlier. Physical examination and computed tomography scan revealed nasolabial cysts bilaterally inferior to the nasal alar region. The cysts were removed via a sublabial approach and endoscopic dacryocystorhinostomy was performed on the right side. Ten months after surgery, the patient was asymptomatic. There may be a correlation, due to embryological reasons, between the presence of nasolabial cysts and the presence of chronic dacryocystitis. Both can be corrected surgically, under the same anaesthesia, without visible scar formation.

    The New Brunswick Market Design Committee has examined several issues regarding the restructuring of the province's electricity sector. This report presents issues that require guidance for implementation, with particular focus on options available for their resolutions. The issues include: (1) rate principles for stranded offer service (SOS) supply, (2) the ability of contestable customers to return to SOS after having left it, (3) whether loads embedded in distribution systems are eligible to participate in the bilateral contract market, (4) whether generators or suppliers can offer capacity and energy to SOS suppliers in competition with the SOS supplier, and (5) details for the balancing market, including pricing, bidding protocols, settlements and how intermittent power sources can participate in the market. A section on pricing for SOS explains pricing principles, the use of export profits, pricing for SOS capacity, and time of use pricing. The Committee has made recommendations for the electricity system in the province to have an energy imbalance service that can move towards a market in order to develop an efficient and effective service. This report also explains pricing in the balancing market, penalties, and settlements. 7 refs

    Bilateral gamma process is widely used in risk management and asset pricing. However the behavioral implications of this process remain unknown. This paper investigates this problem for the first time within the framework of Tauchen and Pitts (1983). With the assumption that there are two types of traders in the market, the optimistic and the pessimistic, we find the bilateral gamma process can be derived from Walrasian equilibrium. This finding establishes the microstructure foundations for the bilateral gamma process.

    A case of bilateral calcaneal epiphysiolysis in a six-month-old female Dobermann Pinscher is described in this report. The absence of a traumatic event and the clinical, radiographic and histopathological abnormalities led us to the diagnosis of simultaneous bilateral epiphysiolysis of the calcaneus. A tension band and a type II transarticular external fixator were placed. The clinical signs were resolved only temporarily because of the gravity of the bone changes.

    Full Text Available Abstract Background Herpes zoster oticus accounts for about 10% cases of facial palsy, which is usually unilateral and complete and full recovery occurs in only about 20% of untreated patients. Bilateral herpes zoster oticus can sometime occur in immunocompromised patients, though incidence is very rare. Case presentation Diabetic male, 57 year old presented to us with bilateral facial palsy due to herpes zoster oticus. Patient was having bilateral mild to moderate sensorineural hearing loss. Patient was treated with appropriate metabolic control, anti-inflammatory drugs and intravenous acyclovir. Due to uncontrolled diabetes, glucocorticoids were not used in this patient. Significant improvement in hearing status and facial nerve functions were seen in this patient. Conclusions Herpes zoster causes severe infections in diabetic patients and can be a cause of bilateral facial palsy and bilateral Ramsay Hunt syndrome. Herpes zoster in diabetic patients should be treated with appropriate metabolic control, NSAIDS and intravenous acyclovir, which we feel should be started at the earliest. Glucocorticoids should be avoided in diabetic patients.

  6. Hybrid fixation in the bilateral sagittal split osteotomy for lower jaw advancement

    Directory of Open Access Journals (Sweden)

    Felipe Ladeira Pereira

    2010-02-01

    Full Text Available Miniplate and screw fixation has been widely used in bilateral sagittal split osteotomy, but some issues remain unclear concerning its lack of rigidity when compared to Spiessl's bicortical technique. This paper demonstrates the hybrid fixation technique in a case report. A 34-year-old female patient underwent a double jaw surgery with counter-clockwise rotation of the mandible fixed using the hybrid fixation technique. The patient evolved well in the postoperative period and is still under follow up after 14 months, reporting satisfaction with the results and no significant deviation from the treatment plan up to now. No damage to tooth roots was done, maxillomandibular range of motion was within normality and regression of the inferior alveolar nerve paresthesia was observed bilaterally. The hybrid mandibular fixation is clearly visible in the panoramic and cephalometric control radiographs. It seems that the hybrid fixation can sum the advantages of both monocortical and bicortical techniques in lower jaw advancement, increasing fixation stability without significant damage to the mandibular articulation and the inferior alveolar nerve. A statistical investigation seems necessary to prove its efficacy.

    To describe the excellent outcome of surgery for bilateral giant retinal tears (GRTs) with better options of endotamponade. This is a case report of a 62-year-old man who presented with bilateral GRTs and associated retinal detachment. The tear in the right eye was supero-temporal and silicone oil was used as an endotamponade. The tear in the left eye was infero-temporal and perfluorocarbon liquid was used as an endotamponade. The outcome at 6 months after surgery was excellent with visual acuities of 6/6 in both eyes. Improved availability of endotamponade agents allows repair of bilateral GRTs to be done at the same time, with good surgical outcomes.

    To present an economic-analysis comparison of simultaneous and sequential bilateral cataract surgery. Helsinki University Eye Hospital, Helsinki, Finland. Economic analysis. Effects were estimated from data in a study in which patients were randomized to have bilateral cataract surgery on the same day (study group) or sequentially (control group). The main clinical outcomes were corrected distance visual acuity, refraction, complications, Visual Function Index-7 (VF-7) scores, and patient-rated satisfaction with vision. Health-care costs of surgeries and preoperative and postoperative visits were estimated, including the cost of staff, equipment, material, floor space, overhead, and complications. The data were obtained from staff measurements, questionnaires, internal hospital records, and accountancy. Non-health-care costs of travel, home care, and time were estimated based on questionnaires from a random subset of patients. The main economic outcome measures were cost per VF-7 score unit change and cost per patient in simultaneous versus sequential surgery. The study comprised 520 patients (241 patients included non-health-care and time cost analyses). Surgical outcomes and patient satisfaction were similar in both groups. Simultaneous cataract surgery saved 449 Euros (€) per patient in health-care costs and €739 when travel and paid home-care costs were included. The savings added up to €849 per patient when the cost of lost working time was included. Compared with sequential bilateral cataract surgery, simultaneous bilateral cataract surgery provided comparable clinical outcomes with substantial savings in health-care and non-health-care-related costs.

    Full Text Available Introduction: The incidence of tumors of the upper urothelium is high in our country, apart from their relation to specific regions (BEN and PBEN and their frequent bilateralism. Bilateral forms are present in significant percentage and are followed, in most cases, by renal failure, which speaks in favor of conservative surgery, if possible. Objective: The aim of the study was to present epidemiological, pathoanatomical and clinical characteristics of bilateral tumors of the upper urothelium and evaluate the Results of their treatment. Method: Our retrospective study analyzed 12 patients with bilateral tumors of the upper urothelium who were treated in the period from 1992 to 1996, according to their epidemiological, clinical, pathoanatomical and pathohistological characteristics, type of surgical treatment and relevant success. Results: In the observed period, bilateral tumors of the upper urothelium were found in 8.2% of our patients. In the group of 12 patients, 5 females and 7 males, 11 cases were from the region of Balkan Endemic Nephropathy (BEN. Renal failure was recorded in high percentage (66%. Radical surgical treatment - total nephroureterectomy was performed in 9 kidney units, and conservative operation in 15 units. Relapse significantly depended on tumor stage and grade, not on type of surgical treatment in the majority of cases. Five-year survival was 58.33%; major cause of death was associated with further evolution of tumor, recurrence and tumor dissemination, respectively, while renal failure complications were the cause of death in one case. Conclusion: The success of treatment mainly depends on tumor stage and grade and not on type of surgical Method in conservative treatment, but renal failure and its complications are an important risk factor in these patients.

    Only a few reports have discussed the detailed clinical symptoms and pathogenesis of bilateral thalamic infarction. The thalamus is composed of different functional nuclei and supplied by vessels containing several variations from the main arteries, leading to difficulty in the precise evaluation of bilateral thalamic infarction. In the present study, we assessed the prognosis of bilateral thalamic infarction based on the distribution of stroke lesions. From among the consecutive ischemic stroke patients admitted to hospital between April 2001 and March 2005, cases of acute bilateral thalamic infarction were selected for this study (n=9; 65.1±13.6 y.o.). The stroke lesions and vascular abnormalities were investigated by magnetic resonance imaging and magnetic resonance angiography on admission. Outcome was evaluated from the modified Rankin scale (mRS) at discharge. Good outcome patients (mRS 0-2; n=5) showed memory disturbance, cognitive impairment and hypersomnia. On the other hand, quadriplegia, oculomotor disturbance and bulbar palsy were observed in the poor outcome patients (mRS≥4; n=4). The critical features of a poor outcome were the age at onset (72.0±15.3 vs. 58.2±11.9 y.o.), inclusion of brainstem lesions and total occlusion of the basilar artery. In conclusion, older age at onset and/or basilar artery occlusion may be critical factors for predicting a poor outcome in bilateral thalamic infarction cases. (author)

  12. Bilateral movements increase sustained extensor force in the paretic arm.

    2018-04-01

    Muscle weakness in the extensors poststroke is a common motor impairment. Unfortunately, research is unclear on whether bilateral movements increase extensor force production in the paretic arm. This study investigated sustained force production while stroke individuals maximally extended their wrist and fingers on their paretic arm. Specifically, we determined isometric force production in three conditions: (a) unilateral paretic arm, (b) unilateral nonparetic arm, and (c) bilateral (both arms executing the same movement simultaneously). Seventeen chronic stroke patients produced isometric sustained force by executing wrist and fingers extension in unilateral and bilateral contraction conditions. Mean force, force variability (coefficient of variation), and signal-to-noise ratio were calculated for each contraction condition. Analysis of two-way (Arm × Type of Condition: 2 × 2; Paretic or Nonparetic Arm × Unilateral or Bilateral Conditions) within-subjects ANOVAs revealed that the bilateral condition increased sustained force in the paretic arm, but reduced sustained force in the nonparetic arm. Further, although the paretic arm exhibited more force variability and less signal-to-noise ratio than the nonparetic arm during a unilateral condition, there were no differences when participants simultaneously executed isometric contractions with both arms. Our unique findings indicate that bilateral contractions transiently increased extensor force in the paretic arm. Implications for Rehabilitation Bilateral movements increased isometric wrsit extensor force in paretic arms and redcued force in nonparetic arms versus unilateral movements. Both paretic and nonparetic arms produced similar force variability and signal-to-noise ratio during bilateral movements. Increased sustained force in the paretic arm during the bilateral condition indicates that rehabilitation protocols based on bilateral movements may be beneficial for functional recovery.

    2013-01-01

    Branchial arch anomalies are one of the most common congenital anomalies that are usually unilateral and bilateral presentation is rare. The simultaneous presence of bilateral second branchial arch anomalies along with bilateral first arch anomalies is extremely rare, with only three such cases reported in the literature. We present two non-syndromic cases of coexisting bilateral first and second arch anomalies. Developmental anomalies of the branchial apparatus account for 17% of all paediatric cervical masses and are the most common type of congenital cervical mass. They usually present in the paediatric age group. About 96–97% of these anomalies are unilateral. Bilateral presentation is seen in 2–3% having a strong familial association. Congenital syndromes also have been associated with first and second branchial arch anomalies. Thorough clinical examination and investigations should be done to rule out these syndromes.

  14. Associations of unilateral whisker and olfactory signals induce synapse formation and memory cell recruitment in bilateral barrel cortices: cellular mechanism for unilateral training toward bilateral memory

    Directory of Open Access Journals (Sweden)

    2016-12-01

    Full Text Available Somatosensory signals and operative skills learned by unilateral limbs can be retrieved bilaterally. In terms of cellular mechanism underlying this unilateral learning toward bilateral memory, we hypothesized that associative memory cells in bilateral cortices and synapse innervations between them were produced. In the examination of this hypothesis, we have observed that paired unilateral whisker and odor stimulations led to odorant-induced whisker motions in bilateral sides, which were attenuated by inhibiting the activity of barrel cortices. In the mice that showed bilateral cross-modal responses, the neurons in both sides of barrel cortices became to encode this new odor signal alongside the innate whisker signal. Axon projections and synapse formations from the barrel cortex, which was co-activated with the piriform cortex, toward its contralateral barrel cortex were upregulated. Glutamatergic synaptic transmission in bilateral barrel cortices was upregulated and GABAergic synaptic transmission was downregulated. The associative activations of the sensory cortices facilitate new axon projection, glutamatergic synapse formation and GABAergic synapse downregulation, which drive the neurons to be recruited as associative memory cells in the bilateral cortices. Our data reveals the productions of associative memory cells and synapse innervations in bilateral sensory cortices for unilateral training toward bilateral memory.

    Full Text Available Bilateral spontaneous tubal ectopic pregnancy is the rarest form of extra uterine pregnancy. The diagnosis is usually made intraoperatively and levels of serum BHCG and ultrasound has not been useful in the diagnosis of bilateral tubal ectopic pregnancy. A 33-year-old woman with 8 weeks amenorrhea and sever lower abdominal pain was admitted. A transvaginal pelvic ultrasound revealed left adnexal mass and massive fluid collection in the pelvis and abdomen. The serum BHCG was 5,700 mIU/ml and in laparotomy bilateral unruptured tubal pregnancy was noted. Left salpingectomy and right salpingostomy were performed. The diagnosis of bilateral spontaneous tubal ectopic pregnancy is usually made intraoperatively. Both tubes at the time of surgery should be closely examined in order to prevent maternal morbidity and mortality.

    2012-01-01

    Full Text Available Bilateral sixth nerve paresis following closed head injury, though rare, is a known entity. However, delayed-onset post-traumatic bilateral abducens paresis is extremely rare. We present two cases. The first patient had onset of bilateral abducens paresis 2 weeks after closed head injury and the second patient after 3 days. The cause in the former was detected to be chronic subdural hematoma and in the latter is speculated to be edema/ischemia due to injury to soft tissue structures housing these nerves. The delayed onset of bilateral abducens paresis following head injury may vary according to the cause. There may be another mechanism of injury apart from direct trauma. Though rare, it needs to be evaluated and may have a treatable cause like elevated intracranial pressure.

    A 57-year-old woman experienced bilateral acute ischemic optic neuropathy after spine surgery. Routine MR imaging sequence, T2-weighted image, showed subtle high signal intensity on bilateral optic nerves. A contrast-enhanced T1 weighted image showed enhancement along the bilateral optic nerve sheath. Moreover, diffusion-weighted image (DWI) and an apparent diffusion coefficient map showed markedly restricted diffusion on bilateral optic nerves. Although MR findings of T2-weighted and contrast enhanced T1-weighted images may be nonspecific, the DWI finding of cytotoxic edema of bilateral optic nerves will be helpful for the diagnosis of acute ischemic optic neuropathy after spine surgery.

    Bilateral anophthalmia is a rare entity and association with septo-optic dysplasia is an even rare condition. The condition is characterized by absent eyeballs in the presence of eyelids, conjunctiva or lacrimal apparatus. Though anophthalmia can be diagnosed clinically, imaging plays a crucial role in delineating the associated anomalies. In addition, often clinical anophthalmia may prove to be severe microphthalmia on imaging. We describe the imaging findings in an infant with bilateral ano...

  20. Bilateral Trade Flows and Income Distribution Similarity

    Science.gov (United States)

    2016-01-01

    Current models of bilateral trade neglect the effects of income distribution. This paper addresses the issue by accounting for non-homothetic consumer preferences and hence investigating the role of income distribution in the context of the gravity model of trade. A theoretically justified gravity model is estimated for disaggregated trade data (Dollar volume is used as dependent variable) using a sample of 104 exporters and 108 importers for 1980–2003 to achieve two main goals. We define and calculate new measures of income distribution similarity and empirically confirm that greater similarity of income distribution between countries implies more trade. Using distribution-based measures as a proxy for demand similarities in gravity models, we find consistent and robust support for the hypothesis that countries with more similar income-distributions trade more with each other. The hypothesis is also confirmed at disaggregated level for differentiated product categories. PMID:27137462

    Bilateral patellar tendon rupture is a rare entity, often associated with systemic diseases and patellar tendinopathy. The authors report a rare case of a 34-year-old man with simultaneous bilateral rupture of the patellar tendon caused by minor trauma. The patient is a retired basketball player with no past complaints of chronic knee pain and a history of steroid use. Surgical management consisted in primary end-to-end tendon repair protected temporarily with cerclage wiring, followed by a short immobilization period and intensive rehabilitation program. Five months after surgery, the patient was able to fully participate in sport activities.

    2018-05-01

    Bilateral true vocal fold paralysis is rarely attributable to inflammatory diseases. Sarcoidosis is a rare but important etiology of bilateral true vocal fold paralysis by compressive lymphadenopathy, granulomatous infiltration, and neural involvement. We describe the first reported case of sarcoidosis presenting as bilateral vocal fold immobility caused by direct fixation by granulomatous infiltration severe enough to necessitate tracheostomy insertion. In addition, we discuss the presentation, the pathophysiology, and the treatment of this disease with a review of the literature of previously reported cases of sarcoidosis-related vocal fold immobility. Sarcoidosis should therefore be an important consideration for the otolaryngologist's differential diagnosis of true vocal fold immobility. Copyright © 2018 The Voice Foundation.

    OBJECTIVE Bilateral chronic subdural hematoma (bCSDH) is a common neurosurgical condition frequently associated with the need for retreatment. The reason for the high rate of retreatment has not been thoroughly investigated. Thus, the authors focused on determining which independent predictors...... are associated with the retreatment of bCSDH with a focus on surgical laterality. METHODS In a national database of CSDHs (Danish Chronic Subdural Hematoma Study) the authors retrospectively identified all bCSDHs treated in the 4 Danish neurosurgical departments over the 3-year period from 2010 to 2012...... that a separated hematoma density and the absence of postoperative drainage were independent predictors of retreatment. CONCLUSIONS In bCSDHs bilateral surgical intervention significantly lowers the risk of retreatment compared with unilateral intervention and should be considered when choosing a surgical...

    Full Text Available Synchronous bilateral upper urinary tract urothelial cancer (UTUC is a very rare form of urothelial cancer. In patients with high-risk unilateral UTUC, radical nephroureterectomy (RNU is the gold standard treatment. However, there is no consensus on the treatment for synchronous bilateral UTUC. Evaluation of the patient and the tumor is recommended. Bilateral nephron-sparing surgery (NSS was performed on a 53-year-old patient who presented with high-risk synchronous bilateral UTUC, and the outcome was reported.

    IgG4-related disease (IgG4-RD) is an idiopathic inflammatory condition that causes pseudotumor formation in single or multiple organs, including those of the head and neck. Temporal bone involvement is rare, with only 3 cases of unilateral temporal bone IgG4-RD described in the literature. We report the first known case of IgG4-RD of bilateral temporal bones and describe its clinical presentation, diagnosis, and treatment. The patient was a 52-year-old man with latent tuberculosis (TB) who presented with a 10-year history of bilateral profound hearing loss and vestibular dysfunction. Computed tomography and magnetic resonance imaging demonstrated bilateral labyrinthine destruction with invasion of the posterior fossa. Immunoglobulin level testing showed elevated total serum IgG levels with normal IgG4 levels. Bilateral mastoidectomies were performed, with biopsy samples demonstrating IgG4 staining with IgG4-positive plasma cells up to 40/HPF (high power field) on the right and 20/HPF on the left, consistent with bilateral IgG4-RD. IgG4-RD of bilateral temporal bones presents with chronic and progressive bilateral hearing loss and vestibular dysfunction. Clinical presentation and radiologic findings are nonspecific, and definitive diagnosis must be made with histopathology and immunostaining. Corticosteroids are therapeutic, but surgical resection may be necessary for temporal bone IgG4-RD to improve long-term remission.

    2013-01-01

    Essure hysteroscopic sterilization is an effective permanent contraception option for women, with a 99.83% effectiveness rate. To date, more than 600,000 Essure procedures have been performed worldwide. This case report describes bilateral Essure insert placement, after which the left insert was subsequently expelled after hysterosalpingogram (HSG)-confirmed correct bilateral insert placement and bilateral tubal occlusion. Although insert expulsion has been reported before a 3-month post-procedure HSG, this is the first published report of expulsion after a confirmatory 3-month post-procedure HSG. Because there now exists documentation of Essure insert expulsion after a 3-month confirmatory HSG, physicians and patients should be informed of this rare occurrence. Further investigation into the causes of such an event is warranted. Copyright © 2013 AAGL. Published by Elsevier Inc. All rights reserved.

  11. Simultaneous bilateral patellar tendon rupture

    Diogo Lino Moura

    Full Text Available ABSTRACT Bilateral patellar tendon rupture is a rare entity, often associated with systemic diseases and patellar tendinopathy. The authors report a rare case of a 34-year-old man with simultaneous bilateral rupture of the patellar tendon caused by minor trauma. The patient is a retired basketball player with no past complaints of chronic knee pain and a history of steroid use. Surgical management consisted in primary end-to-end tendon repair protected temporarily with cerclage wiring, followed by a short immobilization period and intensive rehabilitation program. Five months after surgery, the patient was able to fully participate in sport activities.

    Full Text Available Bilateral anophthalmia is a rare entity and association with septo-optic dysplasia is an even rare condition. The condition is characterized by absent eyeballs in the presence of eyelids, conjunctiva or lacrimal apparatus. Though anophthalmia can be diagnosed clinically, imaging plays a crucial role in delineating the associated anomalies. In addition, often clinical anophthalmia may prove to be severe microphthalmia on imaging. We describe the imaging findings in an infant with bilateral anophthalmia and septo-optic dysplasia.

    1996-09-01

    To study the natural history and retinal findings associated with the intraretinal and subretinal fibrovascular tissues that develop in the late phases of bilateral juxtafoveal telangiectasis. The records of 10 patients (11 eyes) with bilateral juxtafoveal telangiectasis who developed these fibrovascular tissues were examined. Throughout the follow-up period (average 44 months), only 2 eyes (18%) lost 2 or more lines of vision; the final visual acuities were similar for the eyes both with and without fibrovascular tissues. Sixty-four percent of fibrovascular tissues showed little to no growth. Eyes with fibrovascular tissue commonly had retinal pigment epithelial hyperplasia (72%), draining retinal venules (82%), and retinal vascular distortion (64%). Fibrovascular tissues of bilateral juxtafoveal telangiectasis have little proliferative potential and minimal effects on visual acuity. Nevertheless, these fibrovascular tissues do remodel over time, leading to retinal vascular distortion. Given these benign findings, the role of laser photocoagulation treatment of these tissues is questionable.

  15. Multilateral and bilateral agreements

    1993-01-01

    Finland has made both multilateral and bilateral agreements on the exchange of information related to radiation safety. The first arrangements for international agreements and exchange of information were made after the Chernobyl accident. In 1987, Finland joined the convention on early notification of a nuclear power accident coordinated by International Atomic Energy Agency. The convention is applied to accidents that cause of may cause emissions of radioactive substances that might affect the radiation safety of another country. Besides the convention on early notification, some other individual agreements have also been made. These include the International Nuclear Event Scale (INES) system and power companies own information exchange systems. Finland has conducted bilateral agreements with the Nordic countries and the Soviet Union on the notification of accidents and exchange of nuclear power plant information. Today, Russia answers for the Soviet Union's contractual obligations. (orig.)

    Mortensen, Jens Ladefoged

    2014-01-01

    The TTIP will – like other free trade agreements (FTAs) – violate one of the cornerstones of the WTO, i.e. the Most-Favoured-Nation (MFN) principle. However, the multilateral trading system has since 1947 permitted the formation of trading blocks and preferential bilateral trading partnerships....... This contribution asks how the WTO can fulfill its task of ensuring that FTAs do not systematically undermine the multilateral trading order. It focuses on the issue of transparency in the current oversight process and discusses whether the WTO secretariat should be granted a stronger mandate to proactively...... investigate the economic effects of the notified FTAs....

    Full Text Available Background: The ideal treatment for patients presenting with bilateral anterior cruciate ligament (ACL deficiency remains controversial. The purpose was to evaluate cost and mid-term functional results after one-stage bilateral ACL reconstruction using either hamstring or patella tendon autograft.Methods: We compared the mid-term outcome of 7 patients (14 knees who had one-stage bilateral ACL reconstruction with that of a matched group of patients who had unilateral reconstruction (21 patients.Results: The median duration of hospital stay was 4 nights (range 3 to 5 for the bilateral group and 2 nights (range, 1 to 4 for the control group. The duration of rehabilitation process in patients from the control group with unilateral ACL reconstruction was one week shorter (9 versus 8 weeks. In the bilateral group, the median Lysholm score was 96 (range 85–100 and in the control group, the median score was 93 (range 81–100. The median time to return to full-time work and to full sports was 9 weeks and 7 months for the simultaneous bilateral group and 8 weeks and 6 months for the unilateral group. Six patients (86 % in the bilateral group and 17 patients (81 % in the control group were still performing at their pre-injury level of activity. The Health Insurance Institute of Slovenia saves EUR 2,925 when we perform simultaneous bilateral ACL reconstruction instead of two stage ACL reconstruction.Conclusions: Mid-term clinical results suggested that simultaneous bilateral ACL reconstruction using either hamstring or patella tendon autograft is clinically effective. For patients presenting with symptomatic bilateral ACL deficient knees, one stage bilateral ACL reconstruction is reproducible, cost effective, and does not compromise functional results.

  19. Laparoscopic Partial Adrenalectomy for Bilateral Cortisol-secreting Adenomas

    Jeffrey P. Domino

    2007-04-01

    Full Text Available Bilateral cortisol-secreting adenomas are a rare cause of Cushing's syndrome. We report a case of a 35-year-old woman who presented with ACTH-independent Cushing's syndrome and bilateral adrenal adenomas. Adrenal venous sampling confirmed both adenomas to be hyper-secreting cortisol. She underwent bilateral laparoscopic adrenalectomy; total right and partial left adrenalectomies. At 2-year follow-up, she is maintained on low-dose fludrocortisone and hydrocortisone, and without recurrence of hypercorticolism. Laparoscopic partial adrenalectomy is a feasible option for this rare condition; however, long-term follow-up is needed to determine her total independence from steroid usage.

    Full Text Available The case of a female who had severe, rare, terminal breast mucinous carcinoma (BMC and failed to receive surgery and chemotherapy was reported. The patient was diagnosed with pure BMC (ER++, PR++, CerbB-2−, and Ki-67 10% accompanied with bilateral lungs, bilateral chest walls with skin ulcer (D = 14 cm, lymph nodes of bilateral armpits, and right supraclavicular metastases. ECOG (Eastern Cooperative Oncology Group and NRS (Numeric Rating Scale pain scores were 4 and 6, respectively. Because the patient refused traditional chemotherapy and radiotherapy on religious grounds, an herbal medicine containing Panax ginseng, Agrimonia pilosa, and white flower Patrinia herb was administered; extensive nursing for tumor debridement was also provided. Quality of Life (QOL improved and pain reduced. Tumor-bearing survival time was prolonged. The present case dictates that herbal extract medicines and supportive treatment can be helpful for uncommon severe BMC as an appropriate alternative treatment.

    Bilateral cerebellopontine angle (CPA) arachnoid cysts (ACs) are very rare: only one case is reported in literature. Pathogenesis of those cysts is unknown; they are thought to be congenital. The presenting symptoms of CPA AC are frequently nonspecific or otological. The management of ACs of the CPA is controversial. We are reporting two cases of bilateral CPA AC with their pathophysiology and review of literature.

    2006-09-01

    To report the clinical picture of the rare association of nanophthalmos and pigmentary retinal dystrophy and its cataract surgery outcome. We report a case of a 60-year-old female who presented with bilateral slowly progressive visual loss. The patient presented with bilateral light perception visual acuity, exotropia, brunescent cataract hindering fundus examination and hypodontia. Ultrasonography revealed bilateral nanophthalmos. A visual-evoked potential was also performed preoperatively. Cataract surgery with +40D IOL implantation was uneventful. Postoperative fundus examination revealed pigmentary retinal dystrophy, confirmed by electrophysiologic tests. Glycosaminoglycan urinary excretion was normal. Congenital bilateral nanophthalmos may rarely be associated with pigmentary retinal dystrophy. We suggest thorough preoperative evaluation in nanophthalmic eyes for the exclusion of significant features concerning visual prognosis.

    Synchronous bilateral breast cancer is extremely rare in men and has not, up to date, been reported in Korea. A 54-year-old man presented with a palpable mass in the right breast. The right nipple was retracted and bilateral axillary accessory breasts and nipples were present. On physical examination, a 2 cm-sized mass was palpated directly under the right nipple, and, with squeezing, bloody discharge developed in a single duct of the left nipple. There was no palpable mass in the left breast, and axillary lymph nodes were not palpable. Physical examination of external genitalia revealed a unilateral undescended testis on the left side. Synchronous bilateral breast cancer was diagnosed using mammography, ultrasonography, and core-needle biopsy. Histopathological examination revealed invasive ductal carcinoma in the right breast and ductal carcinoma in situ in the left breast. Bilateral total mastectomy, sentinel lymph node biopsy, and excision of accessory breasts in the axilla were performed.

    2017-04-01

    A 30-year-old woman presented to our outpatient department with complaints of pain and swelling in bilateral infrapatellar regions and a discharging sinus in the right knee over the duration of one year. Radiographs showed lytic regions in bilateral patellae. Samples sent from material curetted from sinus yielded no organism but histopathology reported granulomatous inflammation. Following a fresh magnetic resonance imaging (MRI) scan that revealed the infrapatellar pad of fat communicating with the patellar lesions, an exploration and evacuation was done. Material sent revealed epithelioid cell granulomas with caseous necrosis consistent with tuberculosis (TB). The patient was put on first line anti-tubercular treatment (ATT) and has responded favourably with healing of sinus and patellar lesions. Bilateral infrapatellar bursitis is not rare. However patellar TB as a cause for OMIT is not a common diagnosis. A bilateral patellar involvement has not been reported in literature to the best of our knowledge.

    To our knowledge, bilateral supernumerary kidney is a very rare renal abnormality and there are five cases presented in the literature. It is difficult to diagnose supernumerary kidney and clinicians have not detected most cases preoperatively. Laboratory and imaging studies were acquired and carefully examined. The normal laboratory tests were found. Emergency ultrasonography was performed and they revealed no signs of parenchymal abnormality in both kidneys. Serial imaging study including enhanced computed tomography (CT) was performed. An imaging study identified bilateral supernumerary kidney with expanded collecting systems. On each side, significant rotation anomaly was found. In addition, there were two different renal arteries originating from the aorta. This report presents radiological determinations of supernumerary kidney bilaterally in a young man. We think that CT commonly appears to be enough for the diagnosis of supernumerary kidneys

    Sildenafil citrate (Viagra) is one of the frequently prescribed drugs for men with erectile dysfunction. We describe a 52-year-old man with bilateral middle cerebral artery (MCA) territory infarction after sildenafil use. He ingested 100 mg of sildenafil and about 1 h later, he complained of chest discomfort, palpitation and dizziness followed by mental obtundation, global aphasia and left hemiparesis. Brain magnetic resonance imaging documented acute bilateral hemispheric infarction, and cerebral angiography showed occluded bilateral MCA. Despite significant bilateral MCA stenosis and cerebral infarction, systemic hypotension persisted for a day. We presume that cerebral infarction was caused by cardioembolism with sildenafil use.

    2007-01-01

    Background: For women with breast cancer, the contralateral breast is at high risk. The bilateral cancers may be synchronous or metachronous. If the bilateral breast cancers have similar ultrasonography (US) appearances, the US findings of the first breast cancer (index cancer) might lead to early detection of the contralateral cancer. The purpose of this study was to identify the US characteristics of bilateral breast cancer and to determine whether bilateral breast cancers have similar US appearances and whether the US findings for one breast cancer might be predictive of the contralateral breast cancer. Methods: We retrospectively reviewed the US manifestations of 58 patients with surgically proven bilateral primary breast cancer and compared the contralateral cancer with the index cancer by evaluation the margin, shape, inside echoes, posterior attenuation, calcification and color flow signals of 58 lesion pairs to investigate whether the bilateral breast cancers have similar US appearances. Results: Bilateral primary breast cancers were more located in upper outer quadrant, frequently spiculation, taller than wide shape, with irregular margin, heterogeneous internal echo and acoustic shadowing, containing microcalcification and abundant color flow signals. The most common US appearances were taller than wide shape (75.0%, 87/116), irregular margins (79.3%, 92/116) and heterogeneous internal echo (86.2%, 100/116). Of the total 58 lesion pairs, 18 (31.0%) pairs had similar US characteristics, whereas 40 (69.0%) pairs had different US characteristics. Conclusions: US signs of the index cancer do not indicate the most likely appearance of the second cancer in the contralateral breast. Evaluation of the contralateral cancer should be performed without regard for the US findings for the index cancer

    Results. A patient with rheumatoid arthritis presented with bilateral PUK following a 2-month history of ocular discomfort and redness. His systemic prednisolone (PDN and methotrexate (MTX were increased and, despite an initial favorable response, bilateral recurrent corneal perforations ensued. Both eyes underwent cyanoacrylate glue repair, amniotic membrane transplantation (AMT, and penetrating keratoplasty (PKP. Recurrence of the disease and bilateral perforations of the second PKP in both eyes prompted administration of intravenous infliximab immediately after the fourth PKP. The disease activity rapidly settled in both eyes, and at eighteen-month followup, after 12 infliximab infusions, the PUK remains quiescent with no further graft thinning or perforation. Conclusion. Infliximab can be used to arrest the progression of severe bilateral rheumatoid PUK in cases that are refractory to conventional treatment.

    Full Text Available O deslocamento inferior do ombro (luxatio erecta é uma lesão rara, acometendo aproximadamente 0,5% dos deslocamentos dessa articulação. A grande maioria desses casos ocorre unilateralmente. Em setembro de 2004, um homem de 43 anos chegou ao pronto-socorro do Hospital Universitário de Santa Maria (HUSM com queixa de dor bilateral no ombro e incapacidade de abaixar os braços, em consequência de uma queda com os braços abduzidos, enquanto desempenhava sua atividade laboral. Após o exame físico e radiológico constatou- se que o indivíduo apresentava uma luxação inferior bilateral dos ombros. O paciente foi então encaminhado ao bloco cirúrgico onde foi realizada redução incruenta das luxações sob anestesia através da técnica de tração e contra-tração. No dia seguinte recebeu alta com imobilização tipo Velpeau mantendo os ombros totalmente aduzidos e rotados internamente, com orientação de manter a imobilização por três semanas. Foi orientado também a realizar fisioterapia.Inferior shoulder dislocation (luxactio erecta is a rare lesion affecting approximately 0.5% of dislocations of this joint.

    2009-07-01

    The purpose of the present study was to investigate the acute effects of performing a heavy resistance exercise (HRE) protocol on the mechanical variables during a series of bilateral hops. In a block-randomized design, 10 strength trained men performed an HRE or a control treatment before performing 5 series of bilateral hops separated by 2 minutes of passive recovery. Each series of bilateral hops was performed for 15 seconds on a force platform with the subject hopping at a frequency of 2.0 Hz. From the vertical force trace, the vertical force during the countermovement phase of each hop, the negative displacement during the countermovement phase, and the vertical stiffness were calculated. The HRE treatment consisted of performing parallel back squats with 40, 50, 60, and 80% of each subject's 1-repetition maximum after a series of dynamic stretches. The control treatment consisted of the dynamic stretches only. No significant differences in any of the mechanical variables were reported after the 2 treatments (p > 0.05). There were no significant correlations between the absolute maximal strength values and the percent change in any of the mechanical variables after the 2 treatments. Despite the lack of significant changes reported for the group, there were some notable individual responses. It is possible that increases in vertical stiffness during bilateral hops can be achieved after an HRE protocol in certain individuals. However, practitioners should be aware of the specificity issues and the individual nature of the responses to such protocols.

    Full Text Available BACKGROUND Though single sitting myringoplasty using temporalis fascia under general anaesthesia has been documented in many studies, but ours is the first center to have started using tragal cartilage and temporalis fascia harvested from one ear to do bilateral myringoplasty in one sitting using local anaesthesia with excellent results including very good graft uptake rate and audiological improvement without significant complications. The aim of the study is to compare the outcome of bilateral myringoplasty in dry central perforation in one sitting using cartilage on one side and temporalis fascia on the other ear in an urban tertiary care centre. MATERIALS AND METHODS A total of 50 patients above the age of 15 years were included in the study who had dried bilateral perforated ear drum involving pars tensa both sides size of perforation and hearing loss were more or less-matched patients who had persistently discharging ear or had evidence of middle ear infection, granulation tissues, aural polypi, cholesteatoma, ossicular erosion or evidence of sensorineural hearing loss were excluded from the study. In the cases, temporalis fascia graft through postaural incision right side and conchal cartilage was harvested from the right side and endoscopic myringoplasty was performed. Temporalis fascia graft placed by underlay technique and conchal cartilage was used as graft on the left side for all the patients. Patients were followed up after 3 and 6 months to assess closure of tympanic membrane perforation and hearing improvement as depicted by closure of air above gap on pure tone audiometry at 6 months. Study Design- Interventional, descriptive. Place and Duration of Study- Department of ENT, UIORL, Madras Medical College and Rajiv Gandhi Government General Hospital, June 2012 to July 2013. RESULTS A total of 100 myringoplasties were performed on 50 patients included in the study. Majority of the patients included were having medium to large size

    2017-08-01

    Herpes simplex-associated uveitis is usually considered a unilateral eye disease, and rarely included in the differential diagnosis whenever there is bilateral involvement. We report three cases of bilateral herpetic anterior uveitis. We evaluated three patients who presented with clinical manifestations of bilateral uveitis suggestive of viral origin. We found intraocular hypertension, cells in the anterior chamber, paralytic mydriasis, iris atrophy with transillumination defects, and variable anterior vitreous cellularity. According to the clinical findings, supported with herpes-specific antibody titers and aqueous humor PCR results in two of them, they were diagnosed with bilateral anterior herpetic uveitis. Our patients were initially misdiagnosed as having non-infectious uveitis and were treated with immunomodulatory medications, which could have favored the extension of infection bilaterally. Although uncommon, bilateral herpetic uveitis should always be considered in the differential diagnoses, when patients present with hypertensive uveitis in both eyes.

    This article reviews 12 patients with bilateral acoustic neuromas. The sex incidence was equal and the mean age at diagnosis was 26.2 years. The family history was positive in nine of the patients. Five patients have had incomplete surgical removal of acoustic neuromas on both sides. Two of them are completely deaf and the other three have severe sensorineural hearing loss in one ear and no hearing in the other ear. In five patients the tumour on one side has been operated on and the other side is being observed with at least short-term preservation of good hearing. The remaining two patients died of intra-cranial complications, one of them post-operatively. Four patients developed facial palsy immediately following surgery and one developed facial weakness 6 months after surgery. Guidelines are discussed for the care of these patients including the timing of surgery and alternative treatment options (observation, radio-surgery and chemotherapy). This is essentially a group of young individuals who have had multiple operations for bilateral acoustic tumours and associated manifestations and for whom the disease and the sequelae of treatment can be tragic.

    A case of bilateral fibrotic contracture of the infraspinatus muscles in a five-year-old Belgian Shepherd dog is described. The dog was presented with progressive forelimb lameness with postural and gait abnormalities three months after an episode of overexertion. When walking, the lower part of both forelimbs swung in a lateral arc causing a circumduction movement and in the standing position, the dog showed elbow adduction with external rotation of the distal part of both front limbs. Orthopaedic examination revealed bilateral atrophy of both infraspinatus and supraspinatus muscles and restriction in the range of motion of both shoulders, especially when attempting abduction and flexion. No specific findings were observed in the shoulder or elbow radiographs but hyperechogenic areas were evident in the ultrasonographic examination of both infraspinatus muscles. A diagnosis of fibrotic contracture of both infraspinatus muscles was established and bilateral tenectomy of the insertion tendons of the infraspinatus muscles was performed. Complete recovery of the animal was achieved after the surgery, which was confirmed in a long-term follow-up (10 months). In conclusion, physical examination and ultrasonography allowed a proper diagnosis of the condition, and tenectomy of the infraspinatus muscles resulted in a complete recovery of the patient even with bilateral involvement.

    Image smoothing is a fundamental operation in computer vision and image processing. This work has two main thrusts: (1) implementation of a bilateral filter suitable for use in smoothing, or denoising, 3D volumetric data; (2) implementation of the 3D bilateral filter in three different parallelization models, along with parallel performance studies on two modern HPC architectures. Our bilateral filter formulation is based upon the work of Tomasi [11], but extended to 3D for use on volumetric data. Our three parallel implementations use POSIX threads, the Message Passing Interface (MPI), and Unified Parallel C (UPC), a Partitioned Global Address Space (PGAS) language. Our parallel performance studies, which were conducted on a Cray XT4 supercomputer and aquad-socket, quad-core Opteron workstation, show our algorithm to have near-perfect scalability up to 120 processors. Parallel algorithms, such as the one we present here, will have an increasingly important role for use in production visual analysis systems as the underlying computational platforms transition from single- to multi-core architectures in the future.

    To our knowledge, bilateral supernumerary kidney is a very rare renal abnormality and there are five cases presented in the literature. It is difficult to diagnose supernumerary kidney and clinicians have not detected most cases preoperatively. Laboratory and imaging studies were acquired and carefully examined. The normal laboratory tests were found. Emergency ultrasonography was performed and they revealed no signs of parenchymal abnormality in both kidneys. Serial imaging study including enhanced computed tomography (CT) was performed. An imaging study identified bilateral supernumerary kidney with expanded collecting systems. On each side, significant rotation anomaly was found. In addition, there were two different renal arteries originating from the aorta. This report presents radiological determinations of supernumerary kidney bilaterally in a young man. We think that CT commonly appears to be enough for the diagnosis of supernumerary kidneys.

    Cerebrovascular accident and renal hypertension secondary to ureteropelvic junction obstruction (UPJO) are extremely rare. A 6-year-old girl presented with intracranial hemorrhage because of hypertension secondary to the bilateral UPJO. This was successfully treated with craniotomy and subsequent percutaneous nephrostomy placement and bilateral pyeloplasty. Brain computerized tomography revealed right-sided intracranial hemorrhage, and renal ultrasonography confirmed bilateral severe hydronephrosis. Craniotomy with evacuation of intracerebral hematoma and bilateral nephrostomy under ultrasound guidance were performed. One week later, she underwent bilateral pyeloplasty in 2 stages. The patient has been well with normalized renal function and is completely cured of her hypertension in long-term follow-up. Copyright © 2010 Elsevier Inc. All rights reserved.

    Full Text Available Background. The incidence of tubal ectopic gestation caused by schistosomiasis induced tubal pathology is undocumented in this environment, which may be due to rarity of this pathology. Bilateral tubal gestation is common in patients that have undergone in vitro fertilization. We report a hitherto undocumented case of spontaneous bilateral ectopic gestation following tubal schistosomiasis. Case Report. Mrs. OB was a 32-year-old G4P3+0 (3 alive woman who complained of abdominal pain and bleeding per vaginam of 4 and 2 days’ duration respectively following 8 weeks of amenorrhea. A clinical impression of ruptured ectopic gestation was confirmed by ultrasound scanning. She had bilateral salpingectomy with histology of specimens showing bilateral ectopic gestation with Schistosoma haematobium induced salpingitis (findings of Schistosoma haematobium ova noted on slide. Conclusion. Schistosoma induced salpingitis is a rare but possible cause of bilateral tubal gestation.

  6. Bilateral and unilateral ECT: effects on verbal and nonverbal memory.

    1978-11-01

    The memory loss associated with bilateral and nondominant unilateral ECT was assessed with verbal memory tests known to be sensitive to left temporal lobe dysfunction and with nonverbal memory tests known to be sensitive to right temporal lobe dysfunction. Bilateral ECT markedly impaired delayed retention of verbal and nonverbal material. Right unilateral ECT impaired delayed retention of nonverbal material without measurably affecting retention of verbal material. Nonverbal memory was affected less by right unilateral ECT than by bilateral ECT. These findings, taken together with a consideration of the clinical efficacy of the two types of treatment, make what appears to be a conclusive case for unilateral over bilateral ECT.

    OBJECTIVE Bilateral symptoms have been reported in 8%-35% of patients with sacroiliac (SI) joint dysfunction. Stabilization of a single SI joint may significantly alter the stresses on the contralateral SI joint. If the contralateral SI joint stresses are significantly increased, degeneration may occur; alternatively, if the stresses are significantly reduced, bilateral stabilization may be unnecessary for patients with bilateral symptoms. The biomechanical effects of 1) unilateral stabilization on the contralateral SI joint and 2) bilateral stabilization on both SI joints are currently unknown. The objectives of this study were to characterize bilateral SI joint range of motion (ROM) and evaluate and compare the biomechanical effects of unilateral and bilateral implant placement for SI joint fusion. METHODS A lumbopelvic model (L5-pelvis) was used to test the ROM of both SI joints in 8 cadavers. A single-leg stance setup was used to load the lumbar spine and measure the ROM of each SI joint in flexion-extension, lateral bending, and axial rotation. Both joints were tested 1) while intact, 2) after unilateral stabilization, and 3) after bilateral stabilization. Stabilization consisted of lateral transiliac placement of 3 triangular titanium plasma-sprayed (TPS) implants. RESULTS Intact testing showed that during single-leg stance the contralateral SI joint had less ROM in flexion-extension (27%), lateral bending (32%), and axial rotation (69%) than the loaded joint. Unilateral stabilization resulted in significant reduction of flexion-extension ROM (46%) on the treated side; no significant ROM changes were observed for the nontreated side. Bilateral stabilization resulted in significant reduction of flexion-extension ROM of the primary (45%) and secondary (75%) SI joints. CONCLUSIONS This study demonstrated that during single-leg loading the ROMs for the stance (loaded) and swing (unloaded) SI joints are significantly different. Unilateral stabilization for SI

  10. Hardware Implementation of a Bilateral Subtraction Filter

    A bilateral subtraction filter has been implemented as a hardware module in the form of a field-programmable gate array (FPGA). In general, a bilateral subtraction filter is a key subsystem of a high-quality stereoscopic machine vision system that utilizes images that are large and/or dense. Bilateral subtraction filters have been implemented in software on general-purpose computers, but the processing speeds attainable in this way even on computers containing the fastest processors are insufficient for real-time applications. The present FPGA bilateral subtraction filter is intended to accelerate processing to real-time speed and to be a prototype of a link in a stereoscopic-machine- vision processing chain, now under development, that would process large and/or dense images in real time and would be implemented in an FPGA. In terms that are necessarily oversimplified for the sake of brevity, a bilateral subtraction filter is a smoothing, edge-preserving filter for suppressing low-frequency noise. The filter operation amounts to replacing the value for each pixel with a weighted average of the values of that pixel and the neighboring pixels in a predefined neighborhood or window (e.g., a 9 9 window). The filter weights depend partly on pixel values and partly on the window size. The present FPGA implementation of a bilateral subtraction filter utilizes a 9 9 window. This implementation was designed to take advantage of the ability to do many of the component computations in parallel pipelines to enable processing of image data at the rate at which they are generated. The filter can be considered to be divided into the following parts (see figure): a) An image pixel pipeline with a 9 9- pixel window generator, b) An array of processing elements; c) An adder tree; d) A smoothing-and-delaying unit; and e) A subtraction unit. After each 9 9 window is created, the affected pixel data are fed to the processing elements. Each processing element is fed the pixel value for

    Full Text Available Herein, we report a case of nontraumatic bilateral rhegmatogenous retinal detachment (RRD during external beam radiotherapy for nonocular tumor, presented as an observational case study in conjunction with a review of the relevant literature. A 65-year-old male was referred to our hospital due to bilateral RRD. He underwent a biopsy for a tumor of the left frontal lobe 4 months prior to presentation, and the tumor had been diagnosed as primary central nerve system B-cell type lymphoma. He received chemotherapy and external beam radiotherapy for 1 month. There were no traumatic episodes. Bilateral retinal detachment occurred during a series of radiotherapies. Simultaneous nontraumatic bilateral retinal detachment is rare. The effects of radiotherapy on ocular functionality, particularly in cases involving retinal adhesion and vitreous contraction, may include RRD. Thus, it is necessary to closely monitor the eyes of patients undergoing radiotherapy, particularly those undergoing surgery for retinal detachment and those with a history of photocoagulation for retinal tears, a relevant family history, or risk factors known to be associated with RRD.

    Full Text Available Background. We present a rare case of bilateral moyamoya disease presenting as multiple strokes and neurological deficits, treated with the neurosurgical procedure, encephaloduroarteriosynangiosis (EDAS, in a 2-year-old male Pakistani minor. A positive outcome was achieved and the patient recovered fully. Case Summary. Our patient presented with a history of seizures and multiple episodes of hemiparesis (on and off weakness at the age of 2 years. He had a delayed speech development and could not speak more than a few words. He had a slight slurring of speech too. He was diagnosed with bilateral moyamoya disease on Computed Tomography Angiography (CTA. Bilateral EDAS was done in the same year, after which his symptoms improved and patient had moderate functional recovery. Conclusion. A rare disease, moyamoya has been left unexplored in Pakistan; physicians and surgeons when dealing with cases in the pediatric population presenting with symptoms of stroke, signs of generalized weakness, and seizures should consider moyamoya disease as a possibility. Furthermore, this case demonstrates the effectiveness of EDAS procedure for the treatment of moyamoya disease.

    The most common infectious cause of bilateral upper-lobe pulmonary disease is tuberculosis. However, we recently encountered a patient with bilateral apical infiltrates and multiple soft-tissue abscesses caused by Actinomyces odontolyticus. Other findings included fever, weight loss, and leukocytosis, and the patient's only known source of immunosuppression was a long history of alcoholism. There was no history of diabetes, steroid use, or other chronic underlying disease. The diagnosis was made by culture of drainage fluid from one abscess. Therapy with intravenous penicillin G led to rapid clinical improvement and reduction in the infiltrates. To our knowledge, the presentation of pulmonary infection, with bilateral apical infiltrates due to A. odontolyticus has not been previously reported in the medical literature.

    2016-01-01

    Immediately sequential bilateral cataract surgery (ISBCS) is currently a "hot topic" in ophthalmology. There are well-documented advantages in terms of quicker visual rehabilitation and reduced costs. The risk of bilateral simultaneous endophthalmitis and bilateral blindness is now recognized to be minuscule with the advent of intracameral antibiotics and modern management of endophthalmitis. Refractive surprises are rare for normal eyes and with the use of optical biometry. Where a general anesthetic is indicated for cataract surgery, the risk of death from a second anesthetic is much higher than the risk of blindness. A widely recognized protocol from the International Society of Bilateral Cataract Surgeons needs to be adhered to if surgeons wish to start practicing ISBCS.

E-mail: saulocaldas@hotmail.com A case of bilateral queilosquise in a cattle two years old was reported. Clinically, there was cachexia, difficulty in grasping food and water intake. The clinical examination revealed that the nasal orifices were discontinuous with the upper lip, which allowed communication between the nostrils and mouth in its rostral portion, crowding of incisors (tweezers, as well as exposure of medium and the 2nd corner and of the tongue. In this case, the bilateral queilosquise was the result of flaws in fusion of the maxillary process and the medial nasal process and its surroundings, probably due to mineral deficiencies of pregnant cow. This pathogenesis was suggested by excluding other possible causes, the knowledge of the existence of mineral deficiencies in the region where the event occurred and bad nutritional status of pregnant female.

    To determine the clinical efficiency and long-term outcomes between unilateral and bilateral stent insertion in patients with malignant hilar biliary obstruction. From August 2012 to February 2016, 63 consecutive patients with malignant hilar biliary obstruction were treated with unilateral or bilateral stent insertion at our center. The bilateral stents were inserted using the side-by-side technique. The clinical efficiency and long-term outcomes were compared between the two groups. Unilateral and bilateral stent insertions were successfully performed in 31 of 33 and 27 of 30 patients, respectively (P = 0.912). No procedure-related complication occurred. Clinical success was achieved in 29 of 31 patients in the unilateral stent group and in 26 of 27 patients in the bilateral stent group (P = 0.637). During the follow-up, re-obstruction of stent occurred in five patients in the unilateral stent group and in three patients in the bilateral stent group (P = 0.58). The significant differences were not observed in the stent patency time (368 vs. 387 days, P = 0.685) and survival (200 vs. 198 days, P = 0.751) between two groups. Based on the univariate and multivariate analyses, the independent risk factors for decreasing the survival time included higher Eastern Cooperative Oncology Group performance status (P = 0.018), higher alanine aminotransferase level (P = 0.009), and absence of anticancer treatment after stent insertion (P = 0.002). Compared to bilateral stent insertion for malignant hilar biliary obstruction, unilateral stent insertion can provide comparable clinical efficiency and long-term outcomes.

    Renal cell carcinoma (RCC) is a malignant lethal tumour with high potential of metastasis. However, metastasis from RCC to the skin is much less common. It is virtually a sign of poor prognosis. We represent a 42 years old man with bilateral RCC of clear cell type followed by metastasis to the scalp one month later. In this case the relatively young age of the patient, bilaterality of RCC and occurance of skin metastasis in the absence of recurrent kidney tumour are interesting.

  7. Properties of bilateral spinocerebellar activation of cerebellar cortical neurons

    Directory of Open Access Journals (Sweden)

    Pontus eGeborek

    2014-10-01

    Full Text Available We aimed to explore the cerebellar cortical inputs from two spinocerebellar pathways, the spinal border cell-component of the ventral spinocerebellar tract (SBC-VSCT and the dorsal spinocerebellar tract (DSCT, respectively, in the sublobule C1 of the cerebellar posterior lobe. The two pathways were activated by electrical stimulation of the contralateral lateral funiculus (coLF and the ipsilateral LF (iLF at lower thoracic levels. Most granule cells in sublobule C1 did not respond at all but part of the granule cell population displayed high-intensity responses to either coLF or iLF stimulation. As a rule, Golgi cells and Purkinje cell simple spikes responded to input from both LFs, although Golgi cells could be more selective. In addition, a small population of granule cells responded to input from both the coLF and the iLF. However, in these cases, similarities in the temporal topography and magnitude of the responses suggested that the same axons were stimulated from the two LFs, i.e. that the axons of individual spinocerebellar neurons could be present in both funiculi. This was also confirmed for a population of spinal neurons located within known locations of SBC-VSCT neurons and dorsal horn DSCT neurons. We conclude that bilateral spinocerebellar responses can occur in cerebellar granule cells, but the VSCT and DSCT systems that provide the input can also be organized bilaterally. The implications for the traditional functional separation of VSCT and DSCT systems and the issue whether granule cells primarily integrate functionally similar information or not are discussed.

    A 66-year-old male was admitted to our neurosurgical floor because of double vision and gait disturbance. Neurological examinations revealed bilateral 6th nerve palsy with both eyes pointing toward the midline. Initially, using a tentative diagnosis of intracranial mass lesions, especially localized at the base of the skull, computerized tomography of the head, cerebral angiography, orbital venography, and metrizamide CT cisternography were performed; the findings were normal. An orbital CT scan showed an enlargement of the bilateral medial rectus muscles, and the thyroid functions of T 3 and T 4 and the T 3 uptake were all elevated, which was compatible with the diagnosis of Graves' disease. The limitations of both eyeballs were considered to be due not to the 6th nerve palsy, but to the hypertrophy of the bilateral medial rectus muscles. We neurosurgeons should recall Graves' disease as well as intracranial lesions, cerebrovascular disease, and post-traumatic sequelae when examining a patient who presents limitations of external ocular movement.

    Clear cell sarcoma of the kidney (CCSK) accounts for 2-5% of all pediatric renal malignancies, and is known for its propensity to metastasize to bone and other sites. We are reporting two cases with bilateral CCSK that were diagnosed at our institution. One patient initially presented with bilateral renal masses, as well as pulmonary, hepatic and bone metastasis; while other present only with bilateral masses with no evident distant metastasis. Both patients received aggressive neo-adjuvant chemotherapy to decrease tumor size. One patient completed his designated treatment and initially showed complete remission (CR); eventually suffering from relapse. The other patient’s tumor progressed during the course of chemotherapy. Both cases manifested brain dissemination at the time of relapse or progression. This emphasizes the importance of staging stratification in CCSK. This also illustrates CCSK’s ability to metastasize to bone and other sites including the brain (a primary relapse site in our cases)

    The differential diagnosis of bilateral parotid gland enlargement in children includes infectious, inflammatory, and neoplastic disorders. We present the case of a 13-year-old male who presented with a 5-week history of bilateral parotid swelling. On exam, both parotid glands were nontender, smooth, and diffusely enlarged. He had slightly elevated inflammatory markers, but other lab results were normal. A neck CT revealed symmetric enlargement of the parotid, submandibular, and sublingual glands. A chest CT revealed scattered peripheral pulmonary nodules and bilateral hilar adenopathy. A parotid gland biopsy showed multiple noncaseating granulomas with multinucleated giant cells surrounded by lymphocytes, consistent with the diagnosis of sarcoidosis. Special stains for acid-fast and fungal organisms were negative. Using this illustrative case, we discuss the differential diagnosis of bilateral salivary gland enlargement in children and review the etiology, diagnosis, clinical manifestations, and treatment of pediatric sarcoidosis.

    2016-10-01

    Full Text Available The article presents a brief overview of India-U.S. relations during the period of Narendra Modi’s government and Barack Obama’s administration. The author analyzes the dynamics of cooperation development after the victory of Bharatiya Janata Party in the 2014 Parliamentary elections in India and studies the key directions of bilateral agenda. The current condition of India-U.S. strategic dialogue and the influence of human rights issues on the countries’ cooperation are characterized. Since 2014 the states’ cooperation has been growing rapidly. The bilateral investment, trade and economic interdependence have significantly increased. Some experts and mass media note that Barack Obama and Narendra Modi are having friendly relations. From a different angle, a number of agreements between countries still remain unaccomplished. For instance, the U.S. support for India’s permanent seat in the United Nations Security Council, its accession to APEC and the implementation of nuclear deal have yet to be turned into achievement. Together with strengthening the bilateral strategic dialogue, the U.S. has intensified the criticism of India’s human rights record. The main part of it includes the cases of religious intolerance, which are observed in the United States Commission on International Religious Freedom reports and the remarks given by U.S. lawmakers and official representatives, including the Ambassador to India. Washington’s careful attention to the human rights issues and religious violence in particular is one of the major irritants in the U.S.-India relations. The engagement of Indian Americans in the local U.S. politics and their lobbying efforts in the context of U.S.-India relations are revealed. The author outlines the near-terms perspectives of bilateral cooperation.

    Full Text Available Introduction. Homocystinuria is an autosomal recessively inherited defect leading to hyperhomocysteinemia and associated with ocular manifestations, mainly myopia and ectopia lentis. Case outline. A 26-year-old male with secondary glaucoma due to bilateral lens subluxation was admitted to the Department of vitreoretinal surgery. Horizontal nystagmus, bilateral lens subluxation, and bilateral amblyopia were first discovered at the age of three years. Preoperative laboratory workup revealed elevated levels of homocysteine. Bilateral pars plana lensectomy and vitrectomy followed by a sulcus fixation of the intraocular lens (ALCON MA60 Acrysof IOL were performed. The patient was prescribed folic acid, methionine, and pyridoxine, and was urged to maintain a methionine-low diet. After a bilateral lensectomy and sulcus fixation of the intraocular lens and a methionine restriction therapy combined with vitamin B6, B9, and B12 supplementation, his condition improved greatly. Conclusion. In this report of a rare case we emphasize the importance of examining differential diagnoses of lens subluxation, since early intervention can prevent serious complications.

    Hallux valgus is the most common forefoot problem in adults. Although it can cause considerable disability and affect the quality of life of those affected, many patients seek medical attention because of cosmetic concerns. Our aim was to objectively measure the perceived health burden of living with bilateral hallux valgus. Previously validated utility outcome measures, including the visual analog scale, time trade-off, and standard gamble tests, were used to quantify the health burden for single-eye blindness, double-eye blindness, and bilateral hallux valgus in 103 healthy subjects using an online survey. The Student t test and linear regression analysis were used for statistical analysis. The mean visual analog scale, time trade-off, and standard gamble scores for bilateral hallux valgus were 0.86 ± 1.6, 0.95 ± 0.5, and 0.95 ± 0.14, respectively. These were significantly greater than the utility scores for single-eye and double-eye blindness (p hallux valgus. In conclusion, we have objectively demonstrated the effect of living with bilateral hallux valgus deformities. Our sample population reported being willing to undergo a procedure with a 5% mortality rate and sacrifice 1.8 years of life to attain perfect health and avoid the bilateral hallux valgus health state. Our findings will guide us in counseling our patients and understanding how they perceive their foot deformity. Copyright © 2016 American College of Foot and Ankle Surgeons.

  20. Binaural Speech Understanding With Bilateral Cochlear Implants in Reverberation.

    The purpose of this study was to investigate whether bilateral cochlear implant (CI) listeners who are fitted with clinical processors are able to benefit from binaural advantages under reverberant conditions. Another aim of this contribution was to determine whether the magnitude of each binaural advantage observed inside a highly reverberant environment differs significantly from the magnitude measured in a near-anechoic environment. Ten adults with postlingual deafness who are bilateral CI users fitted with either Nucleus 5 or Nucleus 6 clinical sound processors (Cochlear Corporation) participated in this study. Speech reception thresholds were measured in sound field and 2 different reverberation conditions (0.06 and 0.6 s) as a function of the listening condition (left, right, both) and the noise spatial location (left, front, right). The presence of the binaural effects of head-shadow, squelch, summation, and spatial release from masking in the 2 different reverberation conditions tested was determined using nonparametric statistical analysis. In the bilateral population tested, when the ambient reverberation time was equal to 0.6 s, results indicated strong positive effects of head-shadow and a weaker spatial release from masking advantage, whereas binaural squelch and summation contributed no statistically significant benefit to bilateral performance under this acoustic condition. These findings are consistent with those of previous studies, which have demonstrated that head-shadow yields the most pronounced advantage in noise. The finding that spatial release from masking produced little to almost no benefit in bilateral listeners is consistent with the hypothesis that additive reverberation degrades spatial cues and negatively affects binaural performance. The magnitude of 4 different binaural advantages was measured on the same group of bilateral CI subjects fitted with clinical processors in 2 different reverberation conditions. The results of this work

    We present a case of simultaneous bilateral spontaneous pneumothorax caused by a pleuro-pleural communication formed from Nuss procedure for pectus excavatum. A 17-year-old man with a history of Nuss operation complained chest pain and dyspnea. A chest roentgenogram demonstrated a tiny bilateral pneumothorax and two metallic bars inserted at the Nuss procedure. Computed tomography revealed furthermore a bulla in the apex of the left lung. The bilateral pneumothorax critically deteriorated after 4 days from onset and urgent bilateral chest drainages were performed. Nevertheless the drainages the full expansion of both lungs was not obtained and air leakage only from left side was continued. A video-assisted left bullectomy was performed 9 days after the tube insertion. The two bars penetrating anterior mediastinal pleura were thought to be a cause of the simultaneous bilateral spontaneous pneumothorax.

    Describe an unusual case of bilateral pigment dispersion syndrome (PDS) following years of uninterrupted treatment with atropine 1% for bilateral congenital cataracts, speculate on potential mechanisms leading to this condition. This is a case report. A 45-year-old white patient on long-term treatment with atropine 1% ointment since his infancy for bilateral congenital cataracts developed PDS with secondary ocular hypertension. The patient showed all the hallmarks of PDS with secondary ocular hypertension. An anterior segment Swept-Source optical coherence tomography was obtained to review the iris profile. The patient showed good pressure response to topical prostaglandin therapy. This is the second case report of PDS in a patient with chronic use of topical atropine. The proposed mechanisms for pigment dispersion are discussed and the possibility raised of dispersion being a potential side effect of the drug.

    Conclusion:. Surgical outcomes of bilateral reconstructions in patients with abdominal scars are generally comparable with ones in patients without prior surgery; however, some problems have been identified. These procedures might have some intraoperative considerations and often require increased operative times. Apart from the traditional preoperative computed tomography angiography, intraoperative imaging (e.g., fluorescence angiography may be advocated in patients with abdominal scars.

  6. Bilateral femoral head dysplasia and osteochondritis. Multiple epiphyseal dysplasia tarda, spondylo-epiphyseal dysplasia tarda, and bilateral Legg-Perthes disease

    Multiple epiphyseal dysplasia tarda (MEDT) and spondylo-epiphyseal dysplasisa tarda (SEDT) are genetically transmitted conditions affecting the hips, which may resemble bilateral Legg-Perthes disease (LPD). Misdiagnoses are not uncommon, with serious implications for treatment, prognosis and genetic counseling. An epidemiologic study of MEDT and SEDT in a well-defined population of 453 921 persons in Denmark was performed. A population prevalence of 0.7 per 100 000 inhabitants with SEDT and 4.0 per 100 000 inhabitants with MEDT was found. Distinguishing features between MEDT, SEDT and bilateral LPD based on radiologic findings in the hips, other joints, and spine were ascertained. Bilateral LPD is always asymmetric, exhibits patches of increased density in the epiphyses and often metaphyseal cyst-like changes. No spinal lesion or affection of other joints is present, and the acetabula are normal. In MEDT and SEDT the capital femoral epiphyses are symmetrically flattened, fragmented and uniformly slightly sclerotic. Generalised platyspondyly is a constant finding in SEDT.

    To evaluate the mammographic and clinical features of bilateral breast cancer. We retrospectively reviewed clinical records(n=23) and mammograms (n=15) of 23 patients with bilateral breast cancer. Patients' age, location of the tumor and pathologic staging were determined from clinical records. Mammographic features were classified as spiculated mass, nonspiculated mass, mass with microcalcification, microcalcification only, asymmetric density, and normal. Of the 23 cases of bilateral breast cancer, 8(34.8%) were synchronous and 15(65.2%) were metachronous. Age at diagnosis of cancer in the first breast was between 27 and 59(mean 43) years ; there was no statistically significant difference in mean age between patients with synchronous and metachronous cancer. The mean interval between the diagnosis of each lesion of the metachronous pairs was 9.1 years. In 11 of 23 cases(48%), tumors were locaated in the same quadrant, and in the other 12 cases(52%), they were in different quadrant. At mammography, five of 15 metachronous cancers(33%) were similar in appearance and 10 pairs(67%) were different. In 4 of 23 cases(17%), cancer in the first breast was at stage 0 and stage 1, and in 13 of 23(57%), cancer in the second breast was at this same stage. In bilateral breast cancer, the two breasts frequently show different mammographic features. Cancer of the second breast was at an early stage; this suggest that regular examination and mammography are important and can allow early detection of contralateral breast cancer

    Full Text Available The article deals with the author’s interpretation of the process of teaching profession specific bilateral translation to student teacher of English in the Master’s program. The goal of the model of teaching profession specific bilateral translation development is to determine the logical sequence of educational activities of the teacher as the organizer of the educational process and students as its members. English and Ukrainian texts on methods of foreign languages and cultures teaching are defined as the object of study. Learning activities aimed at the development of student teachers of English profession specific competence in bilateral translation and Translation Proficiency Language Portfolio for Student Teachers of English are suggested as teaching tools. The realization of the model of teaching profession specific bilateral translation to student teachers of English in the Master’s program is suggested within the module topics of the academic discipline «Practice of English as the first foreign language»: Globalization; Localization; Education; Work; The role of new communication technologies in personal and professional development. We believe that the amount of time needed for efficient functioning of the model is 48 academic hours, which was determined by calculating the total number of academic hours allotted for the academic discipline «Practice of English as the first foreign language» in Ukrainian universities. Peculiarities of the model realization as well as learning goals and content of class activities and home self-study work of students are outlined.

    Full Text Available Maisonneuve fractures result from a disruption of the medial ankle structures and a proximal fibular fracture. Patient complaints can be misleading and there is a significant rate of delayed diagnosed injuries. We present a case of bilateral Maisonneuve fractures after a fall due to a syncopal collapse. A precise clinical examination led to this rare diagnosis. The injuries were treated with syndesmotic screw fixation, removal of hardware followed after 6 weeks. The patient was asymptomatic at threemonths follow up. Patients with bilateral injuries undergoing standard surgical treatment can gain full recovery, but high suspicion in clinical examination is needed to detect this uncommon bilateral injury.

    We present a case of a patient with Anton's syndrome (i.e., visual anosognosia with confabulations), who developed bilateral occipital lobe infarct. Bilateral occipital brain damage results in blindness, and patients start to confabulate to fill in the missing sensory input. In addition, the patient occasionally becomes agitated and talks to himself, which indicates that, besides Anton's syndrome, he might have had Charles Bonnet syndrome, characterized by both visual loss and hallucinations. Anton syndrome, is not so frequent condition and is most commonly caused by ischemic stroke. In this particular case, the patient had successive bilateral occipital ischemia as a result of massive stenoses of head and neck arteries.

    Full Text Available This case report showing a classical presentation of bilateral fusion of permanent mandibular incisors in a child patient for dental attention. Fusion defined as the merger of two adjacent tooth germs producing one tooth. These teeth may be fused by enamel, dentin, or both. The fused crown is broader than non fused adjacent teeth and thus resembles gemination. However, tooth counting reveals decreased numbers. Fused teeth are rare in the permanent dentition. The incisors are reported to be fused in primary and permanent dentition, but bilateral fusion is a rare occurrence. Hence the case report of bilateral fusion in an 11-year-old boy is presented.

    Meandering pulmonary veins is a rare clinical entity that can be mistaken for more complex congenital syndromes such as hypogenetic lung syndrome. We report imaging findings in a rare incidentally detected case of bilateral meandering pulmonary veins. We briefly discuss the role of imaging in diagnosing this condition, with particular emphasis on contrast-enhanced CT. (orig.)

    Full Text Available Se realizó una investigación descriptiva, transversal y prospectiva de 13 pacientes con isotropía parcialmente acomodativa, después de una corrección total de la hipermetropía, tratados en el Servicio de Oftalmología del Policlínico Pediátrico Sur de Santiago de Cuba desde mayo del 2006 hasta septiembre del 2008. La ejecución de este estudio se justificó por el insuficiente conocimiento existente sobre el alineamiento ocular en las endotropías parcialmente acomodativas, luego de aplicar la técnica de debilitamiento bilateral de los músculos rectos medios. En la serie estudiada, la edad media fue de 6,3 años y el alineamiento ocular logrado en el período posoperatorio resultó exitoso, además de que no estuvo relacionado con la ametropía. La ambliopía encontrada contribuyó al pronóstico de la afección.A descriptive, cross-sectional and prospective investigation of 13 patients with partially accommodative esotropia was carried out, after a total correction of the hypermetropy, treated in the Ophthalmology Service of the Southern Pediatric Polyclinic of Santiago de Cuba from May, 2006 to September, 2008. The implementation of this study was justified for the insufficient existent knowledge on the ocular alignment in the partially accommodative endotropia, after applying the technique of bilateral attenuation of medial rectus muscles. In the studied series, the mean age was of 6,3 years and the ocular alignment achieved in the posoperative period was successful besides that was not related with the ametropia. The amblyopia found contributed to the prognosis of the disorder.

    Full Text Available Elastofibroma dorsi is a rare, slow-growing soſt tissue tumor of the chest wall. The tumor typically located under the lower pole of the scapula. A 57-year-old woman who had retiredas a teacher, presented with a 1-year history of pain on the back and with a 3-month history of swelling located under the leſt scapula. Computed tomography and magnetic resonance imaging showed bilateral, solid soſt tissue tumors under the scapula. She underwent total resection of the tumor on the leſt side. Tumor was diagnosed histopathologically as elastofibroma. Elastofibroma dorsi can be undetermined because of its localization. Radiological examination is important especially on diagnosis of bilateral localization.

    2003-07-01

    Incontinentia Pigmenti is an X-linked dominant neurocutaneous disorder with central nervous system manifestations in 30% of cases, including seizures and mental retardation. Ischemic or hemorrhagic cerebrovascular accidents have been reported rarely in incontinentia pigmenti. Chart review and literature search was performed following identification of the index case. We describe a patient with incontinentia pigmenti who developed bilateral cerebrovascular accidents in the neonatal period, with resultant severe neurologic sequelae. This is the second reported case of bilateral cerebrovascular accidents in a patient with incontinentia pigmenti. This finding may be secondary to cerebrovascular anomalies, similar to those observed in the retina. Recognition of cerebrovascular accidents as a complication of incontinentia pigmenti will hopefully lead to earlier recognition and treatment.

Optou-se pelo tratamento conservador através de redução fechada sob anestesia geral. Ambos os cotovelos foram imobilizados com gesso axilo-palmar e mantidos a 90º de flexão por três semanas, quando se iniciou a reabilitação. No seguimento de dezoito meses observou-se boa estabilidade e recuperação do arco de movimento de ambos os cotovelos.The authors present an isolated case of bilateral lateral dislocation of the elbow joint in a 48-year old female patient. The conservative treatment was chosen, through closed reduction under general anesthesia. Both elbows were placed in an axillopalmar splint cast and held at a 90 degree angle of flexion for three weeks when rehabilitation began. In the eighteen-month follow-up period, good stability as well as the recovery of the range of motion was observed in both elbows

  6. Simultaneous bilateral distal biceps tendon repair: case report

    Directory of Open Access Journals (Sweden)

    Thiago Medeiros Storti

    Full Text Available ABSTRACT Simultaneous bilateral rupture of the distal biceps tendon is a rare clinical entity, seldom reported in the literature and with unclear therapeutic setting. The authors report the case of a 39-year-old white man who suffered a simultaneous bilateral rupture while working out. When weightlifting with elbows at 90° of flexion, he suddenly felt pain on the anterior aspect of the arms, coming for evaluation after two days. He presented bulging contour of the biceps muscle belly and ecchymosis in the antecubital fossa, extending distally to the medial aspect of the forearm, as well as a marked decrease of supination strength and pain in active elbow flexion. MRI confirmed the rupture with retraction of the distal biceps bilaterally. The authors opted for performing the tendon repairs simultaneously through the double incision technique and fixation to the bicipital tuberosity with anchors. The patient progressed quite well, with full return to labor and sports activities, being satisfied with the result after two years of surgery. In the literature search, few reports of simultaneous bilateral rupture of the distal biceps were retrieved, with only one treated in the acute phase of injury. Therefore, the authors consider this procedure to be a good option to solve this complex condition.

  8. An accelerometry-based methodology for assessment of real-world bilateral upper extremity activity.

    Directory of Open Access Journals (Sweden)

    Ryan R Bailey

    Full Text Available The use of both upper extremities (UE is necessary for the completion of many everyday tasks. Few clinical assessments measure the abilities of the UEs to work together; rather, they assess unilateral function and compare it between affected and unaffected UEs. Furthermore, clinical assessments are unable to measure function that occurs in the real-world, outside the clinic. This study examines the validity of an innovative approach to assess real-world bilateral UE activity using accelerometry.Seventy-four neurologically intact adults completed ten tasks (donning/doffing shoes, grooming, stacking boxes, cutting playdough, folding towels, writing, unilateral sorting, bilateral sorting, unilateral typing, and bilateral typing while wearing accelerometers on both wrists. Two variables, the Bilateral Magnitude and Magnitude Ratio, were derived from accelerometry data to distinguish between high- and low-intensity tasks, and between bilateral and unilateral tasks. Estimated energy expenditure and time spent in simultaneous UE activity for each task were also calculated.The Bilateral Magnitude distinguished between high- and low-intensity tasks, and the Magnitude Ratio distinguished between unilateral and bilateral UE tasks. The Bilateral Magnitude was strongly correlated with estimated energy expenditure (ρ = 0.74, p<0.02, and the Magnitude Ratio was strongly correlated with time spent in simultaneous UE activity (ρ = 0.93, p<0.01 across tasks.These results demonstrate face validity and construct validity of this methodology to quantify bilateral UE activity during the performance of everyday tasks performed in a laboratory setting, and can now be used to assess bilateral UE activity in real-world environments.

    2016-07-01

    Full Text Available Background: Extensor mechanism failure secondary to knee replacement could be due to tibial tubercle avulsion, Patellar tendon rupture, patellar fracture or quadriceps tendon rupture. An incidence of Patella tendon rupture of 0.17% and Quadriceps tendon rupture of around 0.1% has been reported after Total knee arthroplasty. These are considered a devastating complication that substantially affects the clinical results and are challenging situations to treat with surgery being the mainstay of the treatment. Case Description: We report here an interesting case of a patellar tendon rupture of one knee and Quadriceps tendon rupture of the contralateral knee following simultaneous bilateral knee replacement in a case of inflammatory arthritis patient. End to end repair for Quadriceps tear and augmentation with Autologous Hamstring tendon graft was done for Patella tendon rupture. OUTCOME: Patient was followed up for a period of 1 year and there was no Extension lag with a flexion of 100 degrees in both the knees. DISCUSSION: The key learning points and important aspects of diagnosing these injuries early and the management techniques are described in this unique case of bilateral extensor mechanism disruption following knee replacements.

    2016-03-01

    To analyze how fibromyalgia affected the variability, asymmetry, and bilateral coordination of gait walking at comfortable and fast speeds. 65 fibromyalgia (FM) patients and 50 healthy women were analyzed. Gait analysis was performed using an instrumented walkway (GAITRite system). Average walking speed, coefficient of variation (CV) of stride length, swing time, and step width data were obtained and bilateral coordination and gait asymmetry were analyzed. FM patients presented significantly lower speeds than the healthy group. FM patients obtained significantly higher values of CV_StrideLength (p=0.04; pGait asymmetry only showed significant differences in the fast condition. FM patients walked more slowly and presented a greater variability of gait and worse bilateral coordination than healthy subjects. Gait asymmetry only showed differences in the fast condition. The variability and the bilateral coordination were particularly affected by FM in women. Therefore, variability and bilateral coordination of gait could be analyzed to complement the gait evaluation of FM patients. Copyright © 2016 Elsevier B.V. All rights reserved.

    Congenital bilateral perisylvian syndrome (CBPS) is a congenital neurological syndrome characterized by pseudobulbar palsy, cognitive deficits and bilateral perisylvian abnormalities observed on imaging. The described abnormality in CBPS is polymicrogyria located in the frontal, parietal, and/or occipital lobes. A few syndromes or abnormalities associated with this syndrome have been documented. Pituitary abnormalities are rare disorders. Association of CBPS with pituitary abnormalities has not been reported previously. In this case, a combination of bilateral perisylvian polymicrogyria with pituitary hypoplasia and ectopic neurohypophysis, caused by a possible single common insult, is presented. (orig.)

    1992-01-01

    Full Text Available A 42 year old man presented with acute bilateral uveitis and necrotizing retinitis. Systemic investigations including test for AIDS and CMV retinitis were negative. Despite oral Acyclovir, both eyes progressed rapidly to retinal detachment with loss of vision. Early recognition is necessary to diagnose the bilateral acute retinal necrosis syndrome and initiate treatment. Bilateral acute retinal necrosis (BARN is a term first coined by Young and Bird in 1978 although the syndrome had been originally described by Urayama et al as an unilateral condition. This syndrome is characterized by the triad of acute confluent peripheral necrotizing retinitis, moderate to severe vasculitis and vitritis in an otherwise healthy individual. Rhegmatogenous retinal detachment occurs within two to three months of the onset of the disease and the second eye is involved in 36% of patients, usually within 6 weeks. We herein report a patient who presented with simultaneous BARN leading to retinal detachment in a matter of days. Also, to our knowledge this is the first report of this condition in India.

    Full Text Available A case is reported of a 9-year old male who presented with abnormal behaviour and progressive diminution of vision. Pupils were middilated in both eyes but the pupillary reflexes were preserved. Fundus examination revealed a bilateral optic atrophy and radiological investigations showed a bilateral occipital calcification. We hereby document a case of retrograde transsynaptic neuronal degeneration of the visual system secondary to bilateral occipital lesions. Transsynapptic neuronal degeneration of optic nerves consequent to occipital lobe lesions is a rare phenomenon. Experimentally occipital lobe ablation in non-human primates has been shown to result in optic atrophy. Herein, we document a case of retrograde transsynaptic neuronal degeneration of the visual system secondary to bilateral occipital lesions.

    In neuro-rehabilitation after stroke, the conventional constrained induced movement therapy (CIMT) has been well-accepted. Existing bilateral trainings are mostly on mirrored symmetrical motion. However, complementary bilateral movements are dominantly involved in activities of daily living (ADLs), and functional bilateral therapies may bring better skill transfer from trainings to daily life. Neurophysiological evidence is also growing. In this work, we firstly introduce our bilateral arm training system realized with a haptic interface and a motion sensor, as well as the tasks that have been designed to train both the manipulation function of the paretic arm and coordination of bilateral upper limbs. Then, we propose quantitative measures for functional assessment of complementary bilateral training performance, including kinematic behavior indices, smoothness, submovement and bimanual coordination. After that, we describe the experiments with healthy subjects and the results with respect to these quantitative measures. Feasibility and sensitivity of the proposed indices were evaluated through comparison of unilateral and bilateral training outcomes. The proposed bilateral training system and tasks, as well as the quantitative measures, have been demonstrated effective for training and assessment of unilateral and bilateral arm functions.

    Laterality in temporal lobe epilepsy is usually defined by EEG and imaging results. We investigated whether the analysis of seizure semiology including lateralizing seizure phenomena identifies bilateral independent temporal lobe seizure onset. We investigated the seizure semiology in 17 patients in whom invasive EEG-video-monitoring documented bilateral temporal seizure onset. The results were compared to 20 left and 20 right consecutive temporal lobe epilepsy (TLE) patients who were seizure free after anterior temporal lobe resection. The seizure semiology was analyzed using the semiological seizure classification with particular emphasis on the sequence of seizure phenomena over time and lateralizing seizure phenomena. Statistical analysis included chi-square test or Fisher's exact test. Bitemporal lobe epilepsy patients had more frequently different seizure semiology (100% vs. 40%; p<0.001) and significantly more often lateralizing seizure phenomena pointing to bilateral seizure onset compared to patients with unilateral TLE (67% vs. 11%; p<0.001). The sensitivity of identical vs. different seizure semiology for the identification of bilateral TLE was high (100%) with a specificity of 60%. Lateralizing seizure phenomena had a low sensitivity (59%) but a high specificity (89%). The combination of lateralizing seizure phenomena and different seizure semiology showed a high specificity (94%) but a low sensitivity (59%). The analysis of seizure semiology including lateralizing seizure phenomena adds important clinical information to identify patients with bilateral TLE. Copyright © 2014 Elsevier B.V.

    Gustavo de Paula Pereira

    Full Text Available OBJECTIVE: To analyze the prenatal outcomes in a cohort of fetuses with mild bilateral pyelectasis and determine whether performing serial ultrasounds is a good follow-up strategy. METHODS: A prospective longitudinal study was conducted on 62 fetuses with mild bilateral pyelectasis. Fetal mild bilateral pyelectasis was considered when the renal pelvis measured (in millimeters ≥5.0 to 10.0, ≥7.0 to 10.0, and ≥10.0 to 15 at ≤23 weeks 6 days, 24 to 31 weeks 6 days, and ≥32 weeks, respectively, with no uretero-calyceal dilatation. Ultrasounds were performed every 3 weeks to assess whether the mild bilateral pyelectasis regressed, remained unchanged (Group 1 or progressed (Group 2. RESULTS: Group 1 consisted of 53 fetuses (85.4%, and progression was observed in 9 cases (Group 2, 14.6%. The initial renal pelvis diameter was significantly larger in fetuses with progression (p=0.028. Statistically significant differences in the renal pelvis diameter were also found at weeks 31 and 35 for both kidneys (p<0.05. The cases requiring intrauterine procedures or early delivery were not observed. CONCLUSION: Fetal mild bilateral pyelectasis with no calyceal dilatation is a benign condition that can be managed in the postnatal period. The initial renal pelvis diameter and the diameter in week 31 or 35 were valuable parameters for identifying cases that would eventually need specific postnatal procedures.

    Full Text Available The aim of this study was to investigate the current surgical management strategy for bilateral breast cancer (BBC patients and to assess the changes in this strategy in China.This is a retrospective review of all patients with early-stage BBC who underwent surgical treatment at the Fudan University Shanghai Cancer Center between June 2007 and June 2014.A total of 15,337 patients with primary breast cancer were identified. Of these patients, 218 (1.5% suffered from synchronous bilateral breast cancer (sBBC, and 296 (2.0% suffered from metachronous bilateral breast cancer (mBBC. Patients with a lobular carcinoma component, those with estrogen receptor-positive cancer, and those with an accompanying sclerosing adenosis in the affected breast tended to develop BBC. The rates of bilateral mastectomy, breast conserving therapy, reconstruction, and combined surgeries were 86.2%, 6.4%, 3.7%, and 3.7%, respectively, for patients with sBBC and 81.1%, 4.4%, 3.0%, and 11.5%, respectively, for patients with mBBC. The interval between bilateral cancers, age at first diagnosis of breast cancer, histopathological type, and stage have significant impacts on the choice of surgery for patients with BBC.Bilateral mastectomy was the dominant surgical management for patients with BBC in China, despite the increased application of breast reconstruction surgery observed in recent years. Bilateral prosthetic breast reconstruction was the ideal choice for patients with sBBC. Chinese surgeons should take responsibility for patient education and inform their patients about their surgical options.

    Full Text Available Spontaneous tegmen tympani defects are rare with even rarer bilateral cases. The symptoms are nonspecific; hence, a high index of suspicion is required to prevent serious intracranial complications. We present a case of spontaneous bilateral tegmen tympani defects with associated meningoencephalocoeles in a 54-year-old male who presented with the signs and symptoms of severe meningitis. After careful workup which included a lumbar puncture, CT and MRI scans, both defects were repaired using a middle fossa approach.

    Localized primary periosteal amyloid tumors are extremely rare. A case of bilateral tibial amyloid tumor is presented. A 62-year-old woman initially presented with a painful mass in the anterior aspect of the right leg. There was no evidence of underlying systemic disease, including chronic infection or malignancy. Based on the results of resistance with Congo red staining to treatment with potassium permanganate and positivity for kappa light chain, we classified this particular case as AL-type amyloidosis. The patient noticed a swelling in the opposite leg 2 years later. The second tumor was also an AL-type amyloidoma. Amyloid tumors are generally solitary. This is the first case of bilateral periosteal amyloid tumors of the AL-type occurring in the tibiae. (orig.)

    The aim of this study was to investigate outcomes in the treatment of bilateral inguinal hernia, comparing the laparoscopic totally extraperitoneal (TEP) and open tension-free mesh repair (LICHT) approaches. We performed a prospective controlled non randomized clinical study in 128 patients with bilateral inguinal hernia over a period of 3 years. LICHT was used in 106 cases (53 patients) while TEP was employed in 150 cases (75 patients). The main outcome measurements were: recurrence rate, operating time, hospital stay and postoperative complications. There were three recurrences (2.3%): two in the LICHT group (3.8%) and one (1.3%) in the TEP group P = NS. The TEP procedure was faster than LICHT repair (48.8 ± 10.8 vs. 70.4 ± 11.2 min) P approach is an effective option for the treatment of bilateral inguinal hernia when performed by experienced surgeons.

    An adult, intact male sugar glider ( Petaurus breviceps ) presented for acute caudal abdominal swelling. Treatment by the referring veterinarian included aspiration of urine from the swelling. On physical examination, mild depression, pale mucus membranes, and caudal abdominal swelling were noted. Focused ultrasonographic assessment revealed a fluid-filled caudal abdominal structure and subjective bladder wall thickening. The following day, the sugar glider was severely depressed. Hematology results included hypoglycemia, hyperkalemia, hyponatremia, and azotemia. Ultrasonography revealed bilateral hydronephrosis and hydroureter. Despite supportive care, the animal died. Postmortem examination confirmed bilateral ureteral dilation, renal petechial hemorrhage, and dilation of the right renal pelvis. Submucosal edema, hemorrhage, and lymphoplasmacytic infiltration of the urinary bladder, ureters, and renal pelvises were noted. Hyperplasia of the urinary bladder and ureteral epithelium, coupled with inflammation, may have caused functional obstruction leading to bilateral hydronephrosis and hydroureter. This is the first reported case of hydronephrosis in a marsupial.

    Full Text Available A 72-year-old man presented with constipation. He was hypertensive and suffered from chronic constipation. On arrival, the patient was fully conscious, and his vital signs were stable. He requested an enema because this treatment had proved effective in the past. On physical examination, a hard palpable mass was detected in the lower abdomen. Computed tomography was performed with contrast media. It revealed an abdominal aortic aneurysm (AAA and bilateral internal iliac artery aneurysms (IIAAs; the latter obstructing the sigmoid colon. We believe that this obstruction was the cause of constipation. The patient underwent Y-graft replacement for the treatment of the AAA and bilateral IIAAs. The surgery was successful, and constipation has not recurred since. As constipation is the most common digestive disorder in the general population, all physicians should be aware that chronic constipation can be caused by bilateral IIAAs.

Methods: All patients who underwent bilateral adrenalectomy for CS at the Department of Endocrine Surgery, Sanjay Gandhi Postgraduate Institute of Medical Sciences hospital between 1991 and 2013 were included. Medical records were reviewed to obtain patient characteristics and follow-up data. Results: Twenty-seven patients were studied. Mean age was 28.74 ± 12.95 years (range 9–60, male:female ratio was 1.7:1. About half that is, 48.19% were of Cushing's disease (failed trans-sphenoidal surgery [TSS], 37.04% were of ectopic CS (ECS, and 14.81% were of CS due to bilateral adrenal pathology. Median follow-up period was 80.5 months. Before surgery, 74.1% patients had body mass index > which after surgery declined to <25 in 75% of them. Hypertension was present in 85.2% and after surgery resolved in 40%. Diabetes mellitus was present in 44.4% and after surgery resolved in 33% of them. Hirsutism and proximal muscle weakness were present in 55.6% and 70.4% patients, respectively, and after surgery improved markedly in all patients. Adrenal crisis developed in 36.3% and Nelson's syndrome in 41.7% patients during follow-up. Three patients died in perioperative period while three succumbed to the disease during follow-up. Two patients developed recurrence of endogenous cortisol production during the follow-up period. Conclusions: Bilateral adrenalectomy is a valid treatment option for palliating severe symptoms in Pituitary Cushing's with failed TSS and unlocalized ECS but the procedure is curative for CS due to bilateral adrenal disease. Overall morbidity and mortality is higher than other endocrine operations. Co-morbidities tend to be more severe and are a risk factor for mortality during the time patient survives.

    2013-06-01

    To report a phenomenon of optical nerve atrophy secondary to lateral occipital lobe infarction. Two successive patients with unilateral occipital lobe infarction who experienced bilateral optical nerve atrophy during the follow-up underwent cranial imaging, fundus photography, and campimetry. Each patient was diagnosed with occipital lobe infarction by cranial MRI. During the follow-up, a bilateral optic atrophy was revealed, and campimetry showed a right homonymous hemianopia of both eyes with concomitant macular division. Bilateral optic atrophy was related to occipital lobe infarction, and a possible explanation for the atrophy was transneuronal degeneration caused by occipital lobe infarction.

    2007-01-01

    Full Text Available The aim of this work is the integration of a virtual environment containing a deformable object, manipulated by an open kinematical chain virtual slave robot, to a bilateral teleoperation scheme based on a real haptic device. The virtual environment of this hybrid bilateral teleoperation system combines collision detection algorithms, dynamical, kinematical and geometrical models with a position–position and/or force–position bilateral control algorithm, to produce on the operator side the reflected forces corresponding to the virtual mechanical interactions, through a haptic device. Contact teleoperation task over the virtual environment with a flexible object is implemented and analysed.

    Adenocarcinoma of the ethmoid sinus is rare, representing only 4 to 8% of malignancies of the paranasal sinuses. An extraordinary case of papillary adenocarcinoma of the ethmoid sinus arising 30 years following high-dose radiotherapy for bilateral retinoblastoma is presented. Second fatal mesenchymal and epithelial primaries have been described in 8.5% of patients with bilateral retinoblastomas previously treated with radiotherapy; however, papillary adenocarcinoma arising within the paranasal sinuses has not been reported. Aggressive treatment including partial maxillectomy, radical pansinusectomy, radical neck dissection followed by regional radiotherapy and systemic chemotherapy failed to prevent the development of fatal hepatic metastases. The high incidence of second fatal primary neoplasms in patients with bilateral retinoblastomas receiving radiation suggests an innate susceptibility that may add to the risk of radiotherapy.

    2013-01-01

    Acute compartment syndrome, a surgical emergency, is defined as increased pressure in an osseofascial space. The resulting reduction of capillary perfusion to that compartment requires prompt fasciotomy. Treatment delay has a poor prognosis, and is associated with muscle and nerve ischemia, resultant infarction, and late-onset contractures. We report a case of traumatic bilateral upper limb acute compartment syndrome associated with anabolic steroids, requiring bilateral emergency fasciotomies. A 25-year-old male bodybuilder taking anabolic steroids, with no past medical history, presented to the Emergency Department 25 min after a road traffic accident. Secondary survey confirmed injuries to both upper limbs with no distal neurovascular deficit. Plain radiographs demonstrated bilateral metaphyseal fractures of the distal humeri. Within 2 h of the accident, the patient developed clinical features that were consistent with bilateral upper arm compartment syndrome. Bilateral fasciotomies of both anterior and posterior compartments were performed, confirming clinical suspicion. We suggest consideration of a history of anabolic steroid use when evaluating patients with extremity trauma. Copyright © 2013 Elsevier Inc. All rights reserved.

  16. Employing a Qualitative Description Approach in Health Care Research.

    Bradshaw, Carmel; Atkinson, Sandra; Doody, Owen

    2017-01-01

    A qualitative description design is particularly relevant where information is required directly from those experiencing the phenomenon under investigation and where time and resources are limited. Nurses and midwives often have clinical questions suitable to a qualitative approach but little time to develop an exhaustive comprehension of qualitative methodological approaches. Qualitative description research is sometimes considered a less sophisticated approach for epistemological reasons. Another challenge when considering qualitative description design is differentiating qualitative description from other qualitative approaches. This article provides a systematic and robust journey through the philosophical, ontological, and epistemological perspectives, which evidences the purpose of qualitative description research. Methods and rigor issues underpinning qualitative description research are also appraised to provide the researcher with a systematic approach to conduct research utilizing this approach. The key attributes and value of qualitative description research in the health care professions will be highlighted with the aim of extending its usage.

    Temporal lobe developmental malformations (TLDM) with focal cortical dysplasia and balloon cells may coexist with mesial temporal sclerosis. The true incidence of this dual pathology is unknown. Our aim was to assess the frequency of amygdala (AM)-hippocampal abnormality in a homogeneous population with this specific developmental malformation. MRI-based volumetry of the AM and hippocampal formation (HF) in 30 patients with unilateral TLDM and intractable partial epilepsy was performed. A volume normalization process defined a normal range of HF and AM volumes in control subjects, and enabled the detection of bilateral volume loss. Normalized volumes detected HF atrophy in 26 patients (nine unilateral and 17 bilateral) and AM atrophy in 18 patients (three unilateral and 15 bilateral). Visual analysis detected unilateral HF abnormality in 21 patients and bilateral abnormality in two. When compared with a group of patients with temporal lobe epilepsy and pure hippocampal sclerosis (N = 92), where volumetry revealed bilateral HF atrophy in 18%, a significant difference in the frequency of bilateral HF atrophy was found (p Dual pathology is frequent in patients with TLDM (87%), and the AM-HF abnormality is often bilateral (57%). Our data suggest that more widespread and potentially epileptogenic lesions coexist with visibly detectable unilateral TLDM. This has implications for the selection of patients for temporal lobe surgery and may influence surgical strategies.

    Bilateral adrenal hemorrhage is an uncommon entity that is difficult to diagnose given the ambiquity of the clinical signs. Computerized tomography plays a major role in the diagnosis, disclosing enlarged adrenal glands presenting the hyperdense aspect that characterizes this disorders. We present a case of bilateral adrenal hemoorrhage in a patient diagnosed as having primary antiphospholipid antibody syndrome, which is a less common cause of adrenal hemorrhage than those classically reported, such as anticoagulant therapy, sepsis, shock and abdominal injury.

    Bilateral tension pneumothorax occurring as a result of recreational activity is exceedingly rare. A 10-year-old boy with no previous respiratory symptoms was involved in a bicycle-to-bicycle collision during play. He was the only one hurt. A few hours later, he was rushed to the general casualty unit of the emergency department of our institution with respiratory distress, diminished bilateral chest excursions and diminished breath sounds. The correct diagnosis was made after a chest radiograph was obtained in the course of resuscitation at the casualty unit. Pleural space needle decompression was suggestive of tension only on the right. Bilateral tube thoracostomies provided effective relief. He was discharged from hospital after a week in excellent health. This case illustrates the need for children to have safety instruction to reduce the risks of recreational bicycling. Chest radiography may be needed to establish the diagnosis of bilateral tension pneumothorax. Needle thoracostomy decompression is not always effective.

    Neck pain is a large clinical problem where reorganized trunk and axioscapular muscle activities have been hypothesised contributing to pain persistence and pain hypersensitivity. This study investigated the effects of bilateral experimental neck pain on trunk and axioscapular muscle function and pain sensitivity. In 25 healthy volunteers, bilateral experimental neck pain was induced in the splenius capitis muscles by hypertonic saline injections. Isotonic saline was used as control. In sitting, subjects performed slow, fast and slow-resisted unilateral arm movements before, during and after injections. Electromyography (EMG) was recorded from eight shoulder and trunk muscles bilaterally. Pressure pain thresholds (PPTs) were assessed bilaterally at the neck, head and arm. Data were normalized to the before-measures. Compared with control and post measurements, experimental neck pain caused (1) decreased EMG activity of the ipsilateral upper trapezius muscles during all but slow-resisted down movements (p neck pain reorganized axioscapular and trunk muscle activity together with local hyperalgesia and widespread hypoalgesia indicating that acute neck pain immediately affects trunk and axioscapular function which may affect both assessment and treatment. Bilateral clinical neck pain alters axioscapular muscle coordination but only effects of unilateral experimental neck pain has been investigated. Bilateral experimental neck pain causes task-dependent reorganized axioscapular and trunk muscle activity in addition to widespread decrease in pressure pain sensitivity. © 2016 European Pain Federation - EFIC®.

  3. Bilateral topographic symmetry patterns across Aphrodite Terra, Venus

    Western Aphrodite Terra, Venus, is characterized by a series of parallel linear structural discontinuities 2000--4000 km in length and 100--200 km wide, which strike at high angles to the general topographic trend of the Aphrodite Terra highlands. The broad chracteristics of the cross-strike discontinuities (CSDs) are similar to both strike-slip fault zones and terrestrial oceanic fracture zones. In an effort to distinguish between these two hypotheses, topographic profiles were taken across Aphrodite Terra to test for bilateral symmetry of the type associated with thermal boundary layer topography at divergent plate boundaries on Earth. In addition to a broad bilateral symmetry at a range of angles across Aphrodite Terra, detailed bilateral symmetry is observed within domains between linear discontinuities in directions generally parallel to the strike of the discontinuities. In addition, within a domain the centers of symmetry of several profiles define a linear rise crest that is oriented normal to the bounding CSDs and terminates against them

    2011-12-01

    Many procedures exist to address the airway restriction often seen with bilateral vocal fold immobility. We review the most recent studies involving arytenoid and/or posterior vocal fold surgery to provide an update on the issues related to these procedures. Specific focus is placed on selection of the surgical approach and operative side, use of adjunctive therapies, and outcome measures including decannulation rate, revision and complication rate, and postoperative results. Ten studies were identified between 2004 and 2011. Modifications to the orginal transverse cordotomy and medial arytenoidectomy techniques continue to be investigated to seek improvement in dyspnea symptoms with minimal decline in voice and/or swallowing function. Decannulation rates for these approaches are high. Postoperative dysphagia appears to be less commonly observed but requires continued study. The use of mitomycin-C in these procedures has been poorly studied to date. Both transverse cordotomy and medial arytenoidectomy procedures result in high success rates. However, many questions related to these procedures remain unanswered, particularly with respect to preoperative and postoperative evaluations of voice quality, swallowing function, and pulmonary status. There is need for rigorous prospective clinical studies to address these many issues further.

    Patellar fractures are uncommon injuries and account for approximately 1% of all fractures. In this article, a 35-year-old male patient who sustained a collision deceleration accident with bilateral comminuted transverse patellar fractures is presented. For this patient, open reduction and internal fixation with tension band technique, using two Kirschner wires and cerclage wire was applied for both fractures. At the first postoperative day, isometric quadriceps and active range of motion exercises were begun and the patient was allowed to walk full weight bearing with two crutches while both extremities were immobilized in a hinged brace allowing maximum 30 degrees of flexion. At postoperative fourth week brace immobilization was terminated. However, the patient was advised to use crutches for two weeks more to prevent any complications that may arise during walking because of the bilaterally of the injury. At six weeks solid union was achieved. During the last visit at postoperative second year, the patient had no complaints and the range of motion was full. In this paper a case of bilateral patella fractures is presented as a consequence of a dashboard injury, and the pathomechanical and therapeutical aspects of such an injury is discussed.

  6. A Digital Image Denoising Algorithm Based on Gaussian Filtering and Bilateral Filtering

    Piao Weiying

    2018-01-01

    Full Text Available Bilateral filtering has been applied in the area of digital image processing widely, but in the high gradient region of the image, bilateral filtering may generate staircase effect. Bilateral filtering can be regarded as one particular form of local mode filtering, according to above analysis, an mixed image de-noising algorithm is proposed based on Gaussian filter and bilateral filtering. First of all, it uses Gaussian filter to filtrate the noise image and get the reference image, then to take both the reference image and noise image as the input for range kernel function of bilateral filter. The reference image can provide the image’s low frequency information, and noise image can provide image’s high frequency information. Through the competitive experiment on both the method in this paper and traditional bilateral filtering, the experimental result showed that the mixed de-noising algorithm can effectively overcome staircase effect, and the filtrated image was more smooth, its textural features was also more close to the original image, and it can achieve higher PSNR value, but the amount of calculation of above two algorithms are basically the same.

    This cooperation started in early 1992 shortly after Lithuania became a newly independent republic. The results from the bilateral co-operation in the field of nuclear safety are very fruitful and promising. The work is progressing in a very efficient and cost-effective way. The pace of progress is to a great extent governed by the resources the Lithuanian partners can allocate. The Swedish Government has up to now allocated more than 200 MSEK (>30 MUSD) for this bilateral cooperation in nuclear safety enhancement. This paper gives an overview of the main content and achievements of the Swedish-Lithuanian cooperation. 1 tab, 2 diagrams

    This paper presents a time sequential Monte Carlo simulation technique to evaluate customer load point reliability in multi-bilateral contracts market. The effects of bilateral transactions, reserve agreements, and the priority commitments of generating companies on customer load point reliability have been investigated. A generating company with bilateral contracts is modelled as an equivalent time varying multi-state generation (ETMG). A procedure to determine load point reliability based on ETMG has been developed. The developed procedure is applied to a reliability test system to illustrate the technique. Representing each bilateral contract by an ETMG provides flexibility in determining the reliability at various customer load points. (authors)

    Full Text Available A previously healthy 22-year-old African American woman presented with bilateral vision loss associated with headache. Her ocular examination was significant for bilateral retinal arterial “boxcarring,” retinal whitening, retinal hemorrhages, and cherry red spots. She was diagnosed with bilateral central retinal artery occlusions and was hospitalized due to concomitant diagnosis of stroke and hypercoagulable state. She was also found to be in heart failure and kidney failure. Rheumatology was consulted and she was diagnosed with catastrophic antiphospholipid syndrome in association with systemic lupus erythematosus. Approximately 7 months after presentation, the patient’s vision improved and remained stable at 20/200 and 20/80.

    2014-08-01

    Bell palsy is a facial nerve neuropathy that is a rare disorder but occurs at higher frequency in pregnancy. Almost 30% of cases are associated with preeclampsia or gestational hypertension. Bilateral Bell palsy occurs in only 0.3%-2.0% of cases of facial paralysis, has a poorer prognosis for recovery, and may be associated with a systemic disorder. We describe a case of a 24-year-old primigravid woman with a twin gestation at 35 weeks diagnosed initially with bilateral facial palsy and subsequently with preeclampsia. She then developed partial hemolysis, elevated liver enzymes, and low platelet count syndrome, prompting the diagnosis of severe preeclampsia, and was delivered. Bilateral facial palsy is a rare entity in pregnancy that may be the first sign of preeclampsia and suggests increased severity of disease, warranting close monitoring.

  13. Generalized approach to bilateral control for EMG driven exoskeleton

    2017-01-01

    Full Text Available The paper discusses a generalized approach to bilateral control for EMG driven exoskeleton systems. In this paper we consider a semi-automatic mechatronic system that is controlled via human muscle activity (EMG level. The problem is to understand how the movement of the exoskeleton effects on the control. The considered system can be described in terms of bilateral control. This means the existence of force feedback from the object via the exoskeleton links and drives to operator. The simulation of the considered model was held on the MATLAB Simulink. The mathematical model of the bilateral system with exoskeleton and operator was developed. Transient functions for different dynamic parameters were obtained. It was shown that force feedback is essential for the R&D of such systems.

    2013-12-01

    This special issue of Fluid Dynamics Research includes nine papers which are based on nine of the presentations at the Second UK-Japan bilateral Workshop and First ERCOFTAC Workshop on 'Turbulent flows generated/designed in multiscale/fractal ways: fundamentals and applications' held from 26 to 27 March 2012 at Imperial College London, UK. The research area of fractal-generated turbulent flows started with a chapter published in 2001 in one of the conference proceedings which came out of the 1999 Isaac Newton Institute 6 month Programme on Turbulence in Cambridge (UK). However, the first results which formed the basis of much of the work reported in this special issue started appearing from 2007 onwards and progress since then could perhaps be described as not insignificant. Research in this area has resulted in the following six notable advances: (a) the definition of two new length-scales characterizing grid-generated turbulence; (b) enhanced and energy-efficient stirring and scalar transfer by fractal grid and fractal openings/flanges with applications, in particular, to improved turbulence generation for combustion; (c) the non-equilibrium turbulent dissipation law; (d) non-equilibrium axisymmetric wake laws; (e) insights into the dependence of drag forces and vortex shedding on the fractal geometry of fractal objects and simulation methods for the calculation of drag of fractal trees; and (f) the invention and successful proof of concept of fractal spoilers and fractal fences. The present special issue contains papers directly related to these advances and can be seen as a reflection of the current research in the field of fractal-generated turbulent flows and their differences and commonalities with other turbulent flows. The financial support from the Japan Society for the Promotion of Science has been decisive for the organization and success of this workshop. We are also grateful to ERCOFTAC who put in place the EU-wide Special Interest Group on multiscale

    Introduction: The patients with testicular germ cell tumors (TGT) present in the contralateral tumor development in approximately 3% of the cases. A small subset presenting with synchronous bilateral tumors (TBS). Case report: Patient is a 41-year study of infertility in who have performed bilateral testicular biopsies. Using ultrasound bilateral testicular nodules were diagnosed predominantly right. It performs a bilateral orchiectomy evidencing bilateral pure classic seminoma (T1 and T4). Staging the regional nodal involvement and distance rule and visceral with normal tumor markers. Receive adjuvant radiotherapy (3060 cGy) including inguinal lymph node chains, and pelvic and lumbo-aortic remaining free of disease at 33 months after surgery. Discussion: 85% of all bilateral TGT metachronous are presented as 15% synchronously. TBS represent less than 1% of the most representative series. In most cases they are seminomas and have been associated with infertility and history Family suggestive of genetic predisposition. Bilateral orchiectomy is local treatment of choice and subsequent planned strategy is according the loco-regional extension stressing the importance of hormone replacement and psychological support. Conclusions: In patients with a family history suggestive or infertile should be evaluated for TBS, especially if it carries a seminoma. the bilateral orchiectomy is local treatment of choice. We found no evidence seminomatous TBS have a worse prognosis compared with patients with unilateral or bilateral metachronous tumors of similar size lesional

    To determine native individual bilateral differences (IBDs) in femoral version in a diverse population. Computed tomography scans with complete imaging of uninjured bilateral femora were used to determine femoral version and IBDs in version. Age, sex, and ethnicity of each subject were also collected. Femoral version and IBDs in version were correlated with demographic variables using univariate and multivariate regression models. One hundred sixty-four subjects were included in the study. The average femoral version was 9.4 degrees (±9.4 degrees). The mean IBD in femoral version was 5.4 degrees (±4.4 degrees, P alignment during intramedullary stabilization of diaphyseal femur fractures. This is also an important consideration when considering malrotation of femur fractures because most studies define malrotation as a greater than 10-15-degree difference compared with the contralateral side.

    Juvenile giant fibroadenoma is a very rare breast disease affecting young girls of premenarche and adolescent ages. It is a benign fibroepithelial tumour characterised by stromal and epithelial proliferation that causes rapidly growing breast mass. Bilateral symmetrical involvement is extremely rare. In this article, we describe this entity in a girl aged 13 years who presented with bilateral gigantically enlarged breasts. Ultrasonography and MRI showed large, multilobulated masses involving both breasts entirely. Endovascular embolisation of bilateral internal mammary arteries and lateral thoracic arteries supplying the masses was performed prior to surgery to reduce their vascularity. The patient subsequently underwent excision of bilateral breast masses and reduction mammoplasty. Histopathologically, bilateral breast masses were confirmed to be juvenile fibroadenomas. 2016 BMJ Publishing Group Ltd.

    Myelolipoma in the mediastinum is an extremely rare entity. In this report, we present the case of a 79-year-old asymptomatic man who had three bilateral paravertebral mediastinal tumors. The three tumors were resected simultaneously using bilateral three-port video-assisted thoracoscopic surgery (VATS). There has been no evidence of recurrence within four years after the operation. Multiple bilateral mediastinal myelolipomas are extremely rare. There are no reports in the English literature of multiple bilateral thoracic myelolipomas that were resected simultaneously using bilateral VATS. We also present characteristic features of myelolipomas, which are helpful for diagnosis. PMID:24782978

  1. Employing a Qualitative Description Approach in Health Care Research

    A qualitative description design is particularly relevant where information is required directly from those experiencing the phenomenon under investigation and where time and resources are limited. Nurses and midwives often have clinical questions suitable to a qualitative approach but little time to develop an exhaustive comprehension of qualitative methodological approaches. Qualitative description research is sometimes considered a less sophisticated approach for epistemological reasons. Another challenge when considering qualitative description design is differentiating qualitative description from other qualitative approaches. This article provides a systematic and robust journey through the philosophical, ontological, and epistemological perspectives, which evidences the purpose of qualitative description research. Methods and rigor issues underpinning qualitative description research are also appraised to provide the researcher with a systematic approach to conduct research utilizing this approach. The key attributes and value of qualitative description research in the health care professions will be highlighted with the aim of extending its usage. PMID:29204457

    Use of the Ilizarov technique for limb lengthening in patients with achondroplasia is controversial, with a high risk of complications balancing cosmetic gains. Although several articles have described the complications of this procedure and satisfaction of patients after surgery, it remains unclear whether lengthening improves the quality of life (QOL) of these patients. We asked whether bilateral lower limb lengthenings with deformity correction in patients with achondroplasia would improve QOL and investigated the correlation between complication rate and QOL. We retrospectively reviewed 22 patients (average age, 12.7 years) diagnosed with achondroplasia who underwent bilateral lower limb lengthenings between 2002 and 2005. These patients were compared with 22 patients with achondroplasia for whom limb lengthening was not performed. The two groups were assessed using the American Academy of Orthopaedic Surgeons (AAOS) lower limb, SF-36, and Rosenberg self-esteem scores. Minimum followup was 4.5 years (range, 4.5-6.9 years). Among the lengthening group, the average gain in length was 10.21 ± 2.39 cm for the femur and 9.13 ± 2.12 cm for the tibia. A total of 123 complications occurred in these 88 segments. The surgical group had higher Rosenberg self-esteem scores than the nonsurgical group although there were no differences in the AAOS and the SF-36 scores. The self-esteem scores decreased with the increase in the number of complications. Our data suggest that despite frequent complications, bilateral lower limb lengthening increases patients' QOL. We believe lengthening is a reasonable option in selected patients. Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

  3. Binaural Pitch Fusion in Bilateral Cochlear Implant Users.

    Binaural pitch fusion is the fusion of stimuli that evoke different pitches between the ears into a single auditory image. Individuals who use hearing aids or bimodal cochlear implants (CIs) experience abnormally broad binaural pitch fusion, such that sounds differing in pitch by as much as 3-4 octaves are fused across ears, leading to spectral averaging and speech perception interference. The goal of this study was to determine if adult bilateral CI users also experience broad binaural pitch fusion. Stimuli were pulse trains delivered to individual electrodes. Fusion ranges were measured using simultaneous, dichotic presentation of reference and comparison stimuli in opposite ears, and varying the comparison stimulus to find the range that fused with the reference stimulus. Bilateral CI listeners had binaural pitch fusion ranges varying from 0 to 12 mm (average 6.1 ± 3.9 mm), where 12 mm indicates fusion over all electrodes in the array. No significant correlations of fusion range were observed with any subject factors related to age, hearing loss history, or hearing device history, or with any electrode factors including interaural electrode pitch mismatch, pitch match bandwidth, or within-ear electrode discrimination abilities. Bilateral CI listeners have abnormally broad fusion, similar to hearing aid and bimodal CI listeners. This broad fusion may explain the variability of binaural benefits for speech perception in quiet and in noise in bilateral CI users.

    The number of cataract surgeries performed globally will continue to rise to meet the needs of an aging population. This increased demand will require healthcare systems and providers to find new surgical efficiencies while maintaining excellent surgical outcomes. Immediately sequential bilateral cataract surgery (ISBCS) has been proposed as a solution and is increasingly being performed worldwide. The purpose of this review is to discuss the advantages and disadvantages of ISBCS. When appropriate patient selection occurs and guidelines are followed, ISBCS is comparable with delayed sequential bilateral cataract surgery in long-term patient satisfaction, visual acuity and complication rates. In addition, the risk of bilateral postoperative endophthalmitis and concerns of poorer refractive outcomes have not been supported by the literature. ISBCS is cost-effective for the patient, healthcare payors and society, but current reimbursement models in many countries create significant financial barriers for facilities and surgeons. As demand for cataract surgery rises worldwide, ISBCS will become increasingly important as an alternative to delayed sequential bilateral cataract surgery. Advantages include potentially decreased wait times for surgery, patient convenience and cost savings for healthcare payors. Although they are comparable in visual acuity and complication rates, hurdles that prevent wide adoption include liability concerns as ISBCS is not an established standard of care, economic constraints for facilities and surgeons and inability to fine-tune intraocular lens selection in the second eye. Given these considerations, an open discussion regarding the advantages and disadvantages of ISBCS is important for appropriate patient selection.

    Full Text Available Introduction Choanal atresia (CA is a challenging surgical problem defined as a failure in the development of communication between the nasal cavity and nasopharynx. Objective The objective of this study is to describe computed tomography (CT findings in cases with bilateral choanal atresia. Methods The study involved performing axial and coronal non-contrast CT scanning with 2–3 mm sections on14 neonates that had bilateral CA. We used fiberoptic nasal endoscopy to confirm the diagnosis. We evaluated coronal CT to study the skull base area in such neonates. Results This study included 14 neonates with bilateral CA; with mean age of 7 ± 3.5 days. Mixed atretic plates were found in 12 (85.7% cases while two (14.3% had pure bony atresia. Isolated CA was detected in 9 cases (64.3% and 5 (35.7% cases had associated anomalies. Coronal CT showed soft tissue density in the nasal cavity that appeared to extend through an apparent defect in the nasal roof (cribriform plate, falsely diagnosed by radiologists as associated encephalocele. At the time of surgical repair, all patients showed thick tenacious mucous secretions in both nasal cavities and revealed no encephalocele. Nasal roof remained intact in all cases. Conclusion The thick secretion of bilateral CA could give a false encephalocele appearance on the CT. It is highly recommended to perform proper suction of the nasal cavity of suspected CA cases just before CT scanning.

    Age-related macular degeneration (AMD) is a common disease causing visual impairment and blindness. Various gene variants are strongly associated with late stage AMD, but little is known about the genetics of early forms of the disease. This study evaluated associations of genetic factors and different AMD stages depending on unilateral and bilateral disease severity. In this case-control study, participants were assigned to nine AMD severity stages based on the characteristics of each eye. 18 single nucleotide polymorphisms (SNPs) were genotyped and attempted to correlate with AMD severity stages by uni- and multivariate logistic regression analyses and trend analyses. Area under the receiver operating characteristic curves (AUC) were calculated. Of 3444 individuals 1673 were controls, 379 had early AMD, 333 had intermediate AMD and 989 showed late AMD stages. With increasing severity of disease and bilateralism more SNPs with significant associations were found. Odds ratios, especially for the main risk polymorphisms in ARMS2 (rs10490924) and CFH (rs1061170), gained with increasing disease severity and bilateralism (exemplarily: rs1061170: unilateral early AMD: OR = 1.18; bilateral early AMD: OR = 1.20; unilateral intermediate AMD: OR = 1.28; bilateral intermediate AMD: OR = 1.39, unilateral geographic atrophy (GA): OR = 1.50; bilateral GA: OR = 1.71). Trend analyses showed pstages was lowest for unilateral early AMD (AUC = 0.629) and showed higher values in more severely and bilaterally affected individuals being highest for late AMD with GA in one eye and neovascular AMD in the other eye (AUC = 0.957). The association of known genetic risk factors with AMD became stronger with increasing disease severity, which also led to an increasing discriminative ability of AMD cases and controls. Genetic predisposition was also associated with the disease severity of the fellow-eye, highlighting the importance of both eyes in AMD patients.

    [Purpose] This study investigated the therapeutic effects of virtual reality-based bilateral upper-extremity training on brain activity in patients with stroke. [Subjects and Methods] Eighteen chronic stroke patients were divided into two groups: the virtual reality-based bilateral upper-extremity training group (n = 10) and the bilateral upper-limb training group (n = 8). The virtual reality-based bilateral upper-extremity training group performed bilateral upper-extremity exercises in a virtual reality environment, while the bilateral upper-limb training group performed only bilateral upper-extremity exercise. All training was conducted 30 minutes per day, three times per week for six weeks, followed by brain activity evaluation. [Results] Electroencephalography showed significant increases in concentration in the frontopolar 2 and frontal 4 areas, and significant increases in brain activity in the frontopolar 1 and frontal 3 areas in the virtual reality-based bilateral upper-extremity training group. [Conclusion] Virtual reality-based bilateral upper-extremity training can improve the brain activity of stroke patients. Thus, virtual reality-based bilateral upper-extremity training is feasible and beneficial for improving brain activation in stroke patients.

    Full Text Available Necrotizing fasciitis (NF is a severe bacterial infection involving fascia and subcutaneous tissue. It generally affects upper or lower extremities unilaterally, and there are few reports of bilateral-extremity NF. Here, we report a case of a 43-year-old male with type 1 diabetes who had NF on the left foot and subsequently developed NF on the other foot 1 week later. The patient survived with antimicrobial therapy and bilateral below-knee amputation. As group B streptococcus (GBS was isolated by blood culture and culture of excised tissues of both feet, bilateral GBS NF of the foot was diagnosed. GBS is a rare causative pathogen in NF; however, there have been two case reports of bilateral GBS NF of an extremity in which NF appeared on the opposite extremity 1 week after the primary site infection, as in our case. GBS was isolated from cultures of blood and excised tissues of both extremities in both cases. Together, these observations suggest that GBS has a potential to cause secondary NF at remote sites by hematogenous dissemination with approximately 1 week delay and thereby lead to bilateral NF.

    Full Text Available Aspergillus endophthalmitis is a devastating inflammatory condition of the intraocular cavities that may result in irreparable loss of vision and rapid destruction of the eye. Almost all cases in the literature have shown an identified source causing aspergillus endophthalmitis as a result of direct extension of disease. We present a rare case of bilateral aspergillus endophthalmitis. A 72-year-old woman with a history of diabetes mellitus, congenital Hirschsprung disease, and recent culture-positive candida pyelonephritis with hydronephrosis status post-surgical stent placement presented with difficulty opening her eyes. She complained of decreased vision (20/200 with pain and redness in both eyes – right worse then left. Examination demonstrated multiple white fungal balls in both retinas consistent with bilateral fungal endophthalmitis. Bilateral vitreous taps for cultures and staining were performed. Patient was given intravitreal injections of amphotericin B, vancomycin, ceftazidime, and started on oral fluconazole. Patient was scheduled for vitrectomy to decrease organism burden and to remove loculated areas of infection that would not respond to systemic antifungal agents. Four weeks after initial presentation, the fungal cultures revealed mold growth consistent with aspergillus. Patient was subsequently started on voriconazole and fluconazole was discontinued due to poor efficacy against aspergillus. Further workup was conducted to evaluate for the source of infection and seeding. Transthoracic cardiogram was unremarkable for any vegetation or valvular abnormalities. MRI of the orbits and sinuses did not reveal any mass lesions or bony destruction. CT of the chest was unremarkable for infection. Aspergillus endophthalmitis may occur because of one of these several mechanisms: hematogenous dissemination, direct inoculation by trauma, and contamination during surgery. Our patient's cause of bilateral endophthalmitis was through an

    Prior to 2009, United Kingdom (UK) public funding was mainly only available for children to receive unilateral cochlear implants. In 2009, the National Institute for Health and Care Excellence published guidance for cochlear implantation following their review. According to these guidelines, all suitable children are eligible to have simultaneous bilateral cochlear implants or a sequential bilateral cochlear implant if they had received the first before the guidelines were published. Fifteen UK cochlear implant centres formed a consortium to carry out a multi-centre audit. The audit involves collecting data from simultaneously and sequentially implanted children at four intervals: before bilateral cochlear implants or before the sequential implant, 1, 2, and 3 years after bilateral implants. The measures include localization, speech recognition in quiet and background noise, speech production, listening, vocabulary, parental perception, quality of life, and surgical data including complications. The audit has now passed the 2-year point, and data have been received on 850 children. This article provides a first view of some data received up until March 2012.

    A functional lesion in corticotrophin (ACTH)-independent Cushing's syndrome is difficult to distinguish from lesions of bilateral adrenal masses. Methods for distinguishing these lesions include adrenal venous sampling and (131)I-6β-iodomethyl-19-norcholesterol ((131)I-NP-59) scintigraphy. We present a case of a 29-year-old Han Chinese female patient with a history of hypercholesterolaemia and polycystic ovary syndrome. She presented with a 6month history of an 8kg body weight gain and gradual rounding of the face. Serial examinations revealed loss of circadian rhythm of cortisol, elevated urinary free-cortisol level and undetectable ACTH level (Cushing's syndrome presenting with bilateral adrenal masses. The clinical presentation of Cushing' syndrome includes symptoms and signs of fat redistribution and protein-wasting features.The diagnosis of patients with ACTH-independent Cushing's syndrome with bilateral adrenal masses is challenging for localisation of the lesion.Both adrenal venous sampling and (131)I-NP-59 scintigraphy are good methods to use in these patients with Cushing's syndrome presenting with bilateral adrenal masses.

    Full Text Available An aneurysmal bone cyst (ABC, usually considered a reactive lesion of bone rather than a cyst or true neoplasm, is believed to represent an exaggerated, localized, proliferative response of vascular tissue in bone. The case described here is of a 40-year-old female patient presenting with gradually increasing bilateral mandibular swelling of more than 1 year duration. The radiographic and cone beam computed tomography (CBCT images showed bilateral, multilocular expansile radiolucent lesions in the mandible in the premolar-molar region. On considering the blood aspirate obtained and the histopathologic findings, the patient was diagnosed with bilateral aneurysmal bone cysts in the mandible, with probable pre-existing bone lesion.

    Full Text Available We present a case of a patient with Anton’s syndrome (i.e., visual anosognosia with confabulations, who developed bilateral occipital lobe infarct. Bilateral occipital brain damage results in blindness, and patients start to confabulate to fill in the missing sensory input. In addition, the patient occasionally becomes agitated and talks to himself, which indicates that, besides Anton’s syndrome, he might have had Charles Bonnet syndrome, characterized by both visual loss and hallucinations. Anton syndrome, is not so frequent condition and is most commonly caused by ischemic stroke. In this particular case, the patient had successive bilateral occipital ischemia as a result of massive stenoses of head and neck arteries.

    Full Text Available Xanthogranulomas (XGRs of the choroid plexus are rare, asymptomatic, and benign lesions usually found incidentally. Here, we present a case of a 47-year-old male with bilateral XGR of the choroid plexus with periventricular edema and discuss our case in relation to a review of existing literature pertaining to the radiology of XGRs. To the best of our knowledge, this is the first reported case of bilateral trigonal XGR causing brain edema without ventricular dilatation. Despite the fact that they can cause hydrocephalus, XGRs are silent and benign lesions. Although the etiopathology of XGRs remains poorly understood, enhanced imaging analyses may provide additional information regarding edema and focal white matter signal changes.

    Burkitt lymphoma, is described as an aggressive form of non-Hodgkin lymphoma of B cells which occurs most often in children and young adults, ovarian lymphoma can appear as a primary lesion or more commonly referred to as a metastasis. Primary ovarian lesions are rare manifestations corresponding to 0.5% of non-Hodgkin lymphoma and 1.5% of ovarian tumors. Clinic case: 31 years old female with general weakness, march incapacity, dyspnea, hyporexia, fever, diaphoresis, weight loss of 20 kg, flat abs with abdominal pain; Ca125 610 U/ml. Abdominal computed tomography shows a solid aspect tumor which affects the right pelvic cavity. Bilateral ovarian tumors were removed. Microscopically, both lesions show a "starry sky" pattern composed by a monotonous infiltration of lymphocytes mixed with large and clear macrophages, several atypical mitoses, and necrosis and hemorrhage areas. Immunohistochemistry was positive for CD10, CD20, and negative for CD3 and high Ki67 proliferation index. Bilateral ovarian Burkitt's lymphoma was diagnosed. Bilateral ovarian Burkitt's lymphoma is a rare entity, with a variability of presentations, the abdominal pain and abdominal tumors are the most frequent. The patient's prognosis at short term is poor, therefore it's necessary to know this entity and make an early diagnosis.

    2018-04-01

    Full Text Available Bilateral vestibulopathy (BVP is a chronic condition in which patients have a reduction or absence of vestibular function in both ears. BVP is characterized by bilateral reduction of horizontal canal responses; however, there is increasing evidence that otolith function can also be affected. Cervical and ocular vestibular-evoked myogenic potentials (cVEMPs/oVEMPs are relatively new tests of otolith function that can be used to test the saccule and utricle of both ears independently. Studies to date show that cVEMPs and oVEMPs are often small or absent in BVP but are in the normal range in a significant proportion of patients. The variability in otolith function is partly due to the heterogeneous nature of BVP but is also due to false negative and positive responses that occur because of the large range of normal VEMP amplitudes. Due to their variability, VEMPs are not part of the diagnosis of BVP; however, they are helpful complementary tests that can provide information about the extent of disease within the labyrinth. This article is a review of the use of VEMPs in BVP, summarizing the available data on VEMP abnormalities in patients and discussing the limitations of VEMPs in diagnosing bilateral loss of otolith function.

    Full Text Available Abstract Introduction Replantation of a limb to the contralateral stump after bilateral traumatic amputations is rare. To the best of our knowledge, there are only a few reports of crossover lower limb replantation in the literature. Case presentation We treated a 37-year-old Chinese woman with bilateral lower limb crush injuries sustained in a traffic accident. Her lower limb injuries were at different anatomic levels. We performed emergency bilateral amputations followed by crossover replantation. Five years later, the woman had recovered well, and had perfect movement and stability in her replanted leg. After reviewing the literature, we thought that presentation of our patient’s case might provide useful information for clinicians. Conclusions Crossover replantation should be considered when evaluating a patient with bilateral lower limb injuries, thus allowing the patient to touch the ground and stand using their own foot.

    A 10-year-old boy, who showed low density areas at bilateral striatal portion on brain CT, was reported. Characteristic clinical features were summarized as follows: 1. Onset in childhood (3 years old), 2. gait disturbance, dysarthria, involuntaly movement such as choreoathetosis and dystonia, 3. mild mental retardation (IQ 70), and 4. slowly progressive course over several years. Family history was unremarkable. His parents were not consanguineous. He was well until 3 years old, when he developed gait disturbance. At the age of 4, CT showed hypodensity lesions in the bilateral putamens, and right caudate was involved at 7, followed by bilateral caudate involvements at 10. Laboratory findings including blood lactate, pyruvate, serum copper, ceruloplasmin, aminoacids, urine and CSF catecholamines were within normal limits. TRH and thiamine therapies were ineffective L-dopa was slightly effective in movements, but symptoms were slowly progressive. We reviewed fourteen reported cases which were similar to our case in their onset, symptoms, clinical course and CT findings. Although the etiology was unknown, this case is possibly a new disease entity. (author)

    Full Text Available Escitalopram is an antidepressant of the selective serotonin reuptake inhibitor(SSRI class. In this manuscript, we report the case of a female patient who developed bilateral acute angle-closure glaucoma induced by escitalopram. A 46-year-old female patient was admitted to our ophthalmology clinic with complaints of severe pain around the both eyes, headache, nausea, and vomiting for two days. In her past medical history, she was using escitalopram for depression for two years. Visual acuity was at hand movement level in both eyes. Anterior segment examination showed bilateral diffuse conjunctival hyperemia, corneal edema, shallow anterior chamber, and fixed dilated pupils. Intraocular pressure was 47 mmHg in the right and 68 mmHg in the left eye. The diagnosis was acute angle-closure glaucoma, and the escitalopram medication was discontinued. She was treated with topical and systemic antiglaucomatous medication. After the cornea become clear, bilateral peripheral laser iridotomy was done. In the following year, she did not begin escitalopram medication again and no other acute angle-closure attack was seen. (Turk J Ophthalmol 2014; 44:396-9

    Dioctophyma renale is a parasite that frequently occurs in animals but rarely in humans. The present report describes the clinical observations of a D. renale infection in a 51-yr-old woman. Its clinical signs and diagnostic findings were unspecific until giant worms were observed in the urine and histological findings confirmed it was a D. renale infection. She refused treatment and died of bilateral renal function failure. This is the first confirmed report to follow the natural progression of D. renale infection in a human. Here, we discuss a conservative therapeutic approach and features associated with this parasitic infection.

    Objective: To assess the changes in regional glucose metabolism following bilateral capsulotomy in patients with medically intractable obsessive-compulsive disorder (OCD). Methods: Eight OCD patients underwent bilateral anterior capsulotomy. 18 F-fluorodeoxyglucose (FDG) PET data obtained before and after operation were subjected to statistical parameter mapping (SPM) . Results: The glucose metabolism decrease was found in the left cingulategyrus, caudatum, left and right thalamic nucleus medialis dorsalis nuclei, bilateral medial and inferior frontal white matter. Conclusion: SPM analysis showed the significant change of cingulate-striatum-thalamic circuits in OCD patients after operation, and the findings implicate that the decreased cerebral metabolism in cingulate gyrus, striatum, and thalamus could be related to bilateral capsulotomy which blocks the abnormal functional connection of corticolimbic loop

    2010-03-01

    Full Text Available Abstract Background Bilateral stroke following radiofrequency catheter ablation is an unusual complication and may result in bilateral altitudinal visual field defects. Bilateral altitudinal visual field defects usually result from prechiasmal pathology causing damage to both retinas or optic nerves and rarely from bilateral symmetric damage to the post chiasmal visual pathways. Case presentation A 48-year-old man complained of visual disturbance on wakening following radiofrequency catheter ablation. The patient had a CHADS score of 1 pre-operatively and no complications were noted intra-operatively. Examination revealed a bilateral superior altitudinal defect and MRI of the brain showed multifocal areas of infarction predominantly involving the occipital lobes which correlated to with the visual deficits. Conclusion While the risk of thromboembolism and perioperative stroke during radiofrequency catheter ablation is small, it is not insignificant.

  16. Mining skeletal phenotype descriptions from scientific literature.

    Directory of Open Access Journals (Sweden)

    Tudor Groza

    Full Text Available Phenotype descriptions are important for our understanding of genetics, as they enable the computation and analysis of a varied range of issues related to the genetic and developmental bases of correlated characters. The literature contains a wealth of such phenotype descriptions, usually reported as free-text entries, similar to typical clinical summaries. In this paper, we focus on creating and making available an annotated corpus of skeletal phenotype descriptions. In addition, we present and evaluate a hybrid Machine Learning approach for mining phenotype descriptions from free text. Our hybrid approach uses an ensemble of four classifiers and experiments with several aggregation techniques. The best scoring technique achieves an F-1 score of 71.52%, which is close to the state-of-the-art in other domains, where training data exists in abundance. Finally, we discuss the influence of the features chosen for the model on the overall performance of the method.

  17. Strategic evaluation of bilateral contract for electricity retailer in restructured power market

    Karandikar, R.G.; Khaparde, S.A.; Kulkarni, S.V.

    2010-01-01

    In a competitive market scenario, consumers make payments for the consumption of electricity to retailers at fixed tariff. The retailers buy power at the Market Clearing Price (MCP) in spot market and/or through bilateral contract at agreed upon price. Due to these different modes at buying and selling ends, the retailers are faced with an involved task of estimating their payoffs along with the risk-quantification. The methodology presented in this paper gives a range of bilateral quantity and associated price for a retailer to ensure risk-constrained payoff. The exercise is carried out with a single retailer in the market as well as for a case of competition amongst two retailers. Risk is quantified using Risk Adjusted Recovery on Capital (RAROC). The problem is evaluated to get a range of bilateral quantity to be quoted for a particular bilateral price at fixed tariff of loyal load and fixed value of switching load. This summary combined with risk-averseness of the retailer leads him to make a judicial choice about bilateral transactions such that it leads to a risk-constrained payoff. (author)

    To describe a technique using labial mucosal flaps to correct stenosis of the nares subsequent to bilateral rostral maxillectomy and nasal planum resection. Case report Client-owned dog. A 10-year-old, neutered male Golden Retriever developed repeated stenosis of the nares, at first after bilateral rostral maxillectomy and nasal planum resection, and again after revision surgery. Bilateral, superior labial mucosal transposition flaps were created and interpolated between the nasal mucosa and skin after debridement of scar tissue. The stenosis did not recur after mucosal flap transposition and the dog returned to normal quality of life (last follow-up 25 months postoperative). Single-stage, superior labial mucosal transposition flaps can be used to correct nares stenosis subsequent to previous surgery. © Copyright 2016 by The American College of Veterinary Surgeons.

    2008-04-01

    Full Text Available Abstract Introduction Popliteal artery aneurysms are the most common peripheral arterial aneurysms, and are frequently bilateral. Acute limb ischemia, rupture and compression phenomena can complicate these aneurysms when the diameter exceeds 2 cm. Case Presentation We report an 82-year-old male patient with two giant femoropopliteal aneurysms, 10.5 and 8.5 cm diameters, managed in our institution. Both aneurysms were resected and a polytetrafluoroethylene (PTFE femoropopliteal interposition graft was placed successfully. Management and literature review are discussed. Conclusion We believe this is the first report in the medical literature of bilateral giant femoropopliteal aneurysms.

  2. Bilateral macular colobomata: Temporal dragging of optic disc

    2015-01-01

    Full Text Available A 13-year-old male presented with decreased vision and squint from childhood. He had bilateral large colobomata at the macula in each eye, the one on the right being larger than the left. The disc was dragged temporally with straightening of the temporal retinal vessels. This is a case report of bilateral large macular coloboma and serves to report its association with a temporally dragged disc and straightened temporal retinal vessels. A dragged disc if present with a colobomatous defect at the macula may strengthen the case for diagnosis of macular coloboma and help exclude other differentials.

  3. A Rare Case of Simultaneous Acute Bilateral Quadriceps Tendon Rupture and Unilateral Achilles Tendon Rupture

    Directory of Open Access Journals (Sweden)

    Wei Yee Leong

    2013-07-01

    Full Text Available Introduction: There have been multiple reported cases of bilateral quadriceps tendon ruptures (QTR in the literature. These injuries frequently associated with delayed diagnosis, which results in delayed surgical treatment. In very unusual cases, bilateral QTRs can be associated with other simultaneous tendon ruptures. Case Report: We present a rare case of bilateral QTR with a simultaneous Achilles Tendon Rupture involving a 31 years old Caucasian man who is a semi-professional body builder taking anabolic steroids. To date bilateral QTR with additional TA rupture has only been reported once in the literature and to our knowledge this is the first reported case of bilateral QTR and simultaneous TA rupture in a young, fit and healthy individual. Conclusion: The diagnosis of bilateral QTR alone can sometimes be challenging and the possibility of even further tendon injuries should be carefully assessed. A delay in diagnosis could result in delay in treatment and potentially worse outcome for the patient. Keywords: Quadriceps tendon rupture; Achilles tendon rupture; Bilateral.

    Laparoscopic adrenalectomy is well established for treatment of adrenal lesions. However, bilateral adrenalectomy for Cushing syndrome is a challenging and time-consuming operation. We report our experience of laparoscopic bilateral adrenalectomy for this disease in 19 patients. From September 2009 to August 2012, we have operated 19 patients with Cushing syndrome and performed bilateral laparoscopic adrenalectomy using the transperitoneal approach; synchronous in 15 patients and staged in 4 patients. In 15 patients, the surgery was carried out sequentially on both the sides in lateral position with intraoperative change in position. Complete adrenalectomy including periadrenal fat was carried out on both the sides. Nineteen patients were referred from Department of Endocrinology for bilateral adrenalectomy for adrenocorticotropin hormone (ACTH)-dependent and ACTH-independent Cushing syndrome. The indications for surgery were Cushing disease in 15 patients, occult/ectopic source of ACTH in 2 patients, and primary adrenal hyperplasia in 2 patients. Fifteen patients underwent bilateral adrenalectomy during the same operation. Four patients underwent staged procedures. All procedures were completed laparoscopically with no conversions. The mean operating time for simultaneous bilateral adrenalectomy was 210 minutes (range, 150 to 240 min). This included the repositioning and reprepping time. There were no major intraoperative complications. The average blood loss was 100 mL (range, 50 to 200 mL). None of the patients required blood transfusions in the postoperative period. The postoperative complications included minor port-site infection in 2 patients. One severely debilitated patient died on the 14th postoperative day because of hospital-acquired pneumonia. The remaining 18 patients have done well in terms of impact on the disease. Laparoscopic bilateral adrenalectomy for Cushing syndrome is feasible and safe. It confers all the advantages of minimally invasive

    Bilateral high signal intensity in basal ganglia on T1-weighted images is unusual, the purpose of this study is to describe the pattern of high signal intensity and underlying disease. During the last three years, 8 patients showed bilateral high signal intensity in basal ganglia on T1-weighted image, as compared with cerebral white matter. Authors analyzed the images and underlying causes retrospectively. Of 8 patients, 5 were male and 3 were female. The age ranged from 15 days to 79 years. All patient were examined by a 0.5T superconductive MRI. Images were obtained by spin echo multislice technique. Underlying causes were 4 cases of hepatopathy, 2 cases of calcium metabolism disorder, and one case each of neurofibromatosis and hypoxic brain injury. These process were bilateral in all cases and usually symmetric. In all cases the hyperintense areas were generally homogenous without mass effect or edema, although somewhat nodular appearance was seen in neurofibromatosis. Lesions were located in the globus pallidus and internal capsule in hepatopathy and neurofibromatosis, head of the caudate nucleus in disorder of calcum metabolism, and the globus pallidus in hypoxic brain injury. Although this study is limited by its patient population, bilateral hyperintense basal ganglia is associated with various disease entities. On analysis of hyperintense basal ganglia lesion, the knowledge of clinical information improved diagnostic accuracy

    Full Text Available Sudden bilateral hearing loss are seen rarely and the toxic substance exposure constitutes a small part of etiology. A Fifty-eight-year-old woman admitted to our clinic with sudden bilateral hearing loss shortly after chlorpyrifos-ethyl exposure. Otolaryngologic examination findings were normal. The patient had 40 dB sensorineural hearing loss (SNHL on the right ear and 48 dB SNHL on the left ear. Additional diagnostic tests were normal. The conventional treatment for sudden hearing loss was performed. On the second week following organophosphate (OP exposure the patient's hearing loss almost completely resolved. OP's are heavily used in agriculture and should be taken into consideration as an etiologic factor in sudden hearing loss. Keywords: Organophosphates, Hearing loss, Sudden

  7. Primary Bilateral Non-Hodgkin's Lymphoma of the Adrenal Gland: A Case Report

    Directory of Open Access Journals (Sweden)

    Ahmed Amine Bouchikhi

    2012-01-01

    Full Text Available Primary bilateral non-Hodgkin's lymphoma (NHL of the adrenal gland is a very rare entity. Indeed less than 60 cases have been reported in the literature. Hence, we report a case of high-grade lymphoma of both adrenal glands that was found in a young patient of 32 years of age. The patient was admitted in the emergency department of our hospital with a profile of hemorrhagic shock. After stabilization, the imaging investigations demonstrated large bilateral adrenal masses. The CT-scan guided biopsy of both adrenal glands allowed the diagnosis of primary bilateral adrenal NHL. The patient died after the first chemotherapy session. The presence of bilateral adrenal masses associated with a rapid increase of volume should raise the diagnosis of primary adrenal non-Hodgkin's lymphoma.

    Full Text Available Purpose: To report the first simultaneous onset of bilateral acute depigmentation of the iris (BADI in two siblings. Observations: Two sisters presented with bilateral ocular pain, redness and light sensitivity. Examination revealed bilateral circulating pigment in the anterior chamber with pigment dusting on backs of the corneas, patchy iris depigmentation and heavy pigment deposition in the angle. Both patients had recently suffered from upper respiratory tract infections. Bilateral visual acuities were preserved and no transillumination defects were observed. The patients were diagnosed with BADI. Both cases were successfully controlled with topical corticosteroids and anti-glaucoma drops as well as topical glanciclovir gel. Conclusions and Importance: To date, there had been no published reports of BADI in the Middle East and Africa. This is the first observation of this entity in these regions. Moreover it is the first occurrence of BADI in two immediate siblings simultaneously. We also report the rare asymmetrical presentation with BADI in one of our patients. These observations point to the possibility of genetic factors underlying BADI as well as an infectious cause behind the etiology.

    Controversy exists on optimal endoscopic management for palliation of malignant hilar obstruction, with advocates for metal "side-by-side" (SBS) and "stent-in-stent" (SIS) techniques. We sought to evaluate the technical feasibility, efficacy, and outcomes of bilateral biliary self-expanding metal stents (SEMS) for treatment of malignant hilar obstruction using a stent with a 6Fr delivery system. This was a single-center, retrospective review of all patients who underwent bilateral placement of Zilver® biliary SEMS for malignant hilar obstruction from January 2010 to August 2012. Patients underwent endoscopic retrograde cholangiopancreatography with placement of stents using either the SIS or SBS stent techniques. Twenty-four patients (19 men, mean age 63 years) underwent bilateral stenting for malignant hilar obstruction during the study period. Seventeen and seven patients underwent the SBS and SIS technique, respectively. Cholangiocarcinoma (n=14) was the most common cause of hilar obstruction. Initial technical success was achieved in 24/24 (100%) of patients; however, 12 (50%) patients required re-intervention during the study period (median 98 days). Comparison of the SBS and SIS groups revealed no statistical difference with respect to need for re-intervention (P=0.31), successful re-intervention (P=0.60), or procedural length (P=0.89). Use of bilateral Zilver® SEMS in either the SBS or SIS configuration is safe, technically feasible, and effective for drainage of malignant hilar obstruction; however, duration of stent patency and procedure-free survival remain variable.

    Full Text Available Bilateral PDA dependent pulmonary circulation with right and left pulmonary artery discontinuity is very rare. Limited data available for bilateral PDA stenting. Bilateral PDA stenting in nonconfluent pulmonary arteries is challenging procedure but can be considered as an option in the management of complex conditions like this. 12 days old Preterm (36 weeks gestation male baby with birth weight of 2.6 kg developed respiratory distress with severe cyanosis and desaturation upto 50%. Baby was intubated and started on Prostaglandin 0.05 mic/kg/mt. His saturation improved to 80%. Echocardiogram showed complex cyanotic heart disease, Situs ambiguous, dextrocardia, complete unbalanced AV septal defect, pulmonary atresia , nonconfluent small branch pulmonary arteries supplied by the bilateral patent ductus arteriosus (PDA from right aortic arch and all four pulmonary veins form a confluence and drain into superior vena cava(SVC through vertical vein with no obstruction. Baby was taken up for PDA stenting. descending aortogram showed right aortic arch with vertical tortuous duct to right pulmonary artery (RPA and another short duct with acute angle from left subclavian artery to left pulmonary artery (LPA . Both ducti stented with coronary stents. Vertical vein angiogram showed both lungs drain to a confluence and then to SVC via ascending vertical vein with no obstruction. After stenting lung perfusion improved and the baby was stable and maintained 80% saturation on room air. Bilateral PDA dependent pulmonary circulation with right and left pulmonary artery discontinuity is very rare. Our case is unique with Heterotaxy, TAPVC, Dextrocardia and double ducti. Eventhough bilateral ductal stenting is technically challenging it is successful through femoral artery approach.

  14. Central Lesions With Selective Semicircular Canal Involvement Mimicking Bilateral Vestibulopathy

    Directory of Open Access Journals (Sweden)

    Luke Chen

    2018-04-01

    Full Text Available Bilateral vestibulopathy (BVP, which is due to peripheral lesions, may selectively involve certain semicircular canal (SCC. Recent eye movement recordings with search coil and video head impulse test (HIT have provided insight in central lesions that can cause bilateral and selective SCC deficit mimicking BVP. Since neurological signs or ocular motor deficits maybe subtle or absent, it is critical to recognize central lesions correctly since there is prognostic and treatment implication. Acute floccular lesions cause bilateral horizontal SCC (HC impairment while leaving vertical SCC function unaffected. Vestibular nuclear lesions affect bilateral HC and posterior SCC (PC function, but anterior SCC (AC function is spared. When both eyes are recorded, medial longitudinal fasciculus lesions cause horizontal dysconjugacy in HC function and catch-up saccades, as well as selective deficiency of PC over AC function. Combined peripheral and central lesions may be difficult to distinguish from BVP. Anterior inferior cerebellar artery stroke causes two types of deficits: 1. ipsilateral pan-SCC deficits and contralateral HC deficit and 2. bilateral HC deficit with vertical SCC sparing. Metabolic disorders such as Wernicke encephalopathy characteristically involve HC but not AC or PC function. Gaucher disease causes uniform loss of all SCC function but with minimal horizontal catch-up saccades. Genetic cerebellar ataxias and cerebellar-ataxia neuropathy vestibular areflexia syndrome typically do not spare AC function. While video HIT does not replace the gold-standard, search coil HIT, clinicians are now able to rapidly and accurately identify specific pattern of SCC deficits, which can aid differentiation of central lesions from BVP.

    1977-01-01

    Over 300 cases of femoral neck fractures following radiotherapy for intrapelvic malignant tumor have been reported in various countries since Baensch reported this disease in 1927. In Japan, 40 cases or so have been reported, and cases of bilateral femoral neck fractures have not reached to ten cases. The authors experienced a case of 75 year-old female who received radiotherapy for cancer of the uterus, and suffered from right femoral neck fracture 3 months after and left femoral neck fracture one year and half after. As clinical symptoms, she had not previous history of trauma in bilateral femurs, but she complained of a pain in a hip joint and of gait disturbance. The pain in left femoral neck continued for about one month before fracture was recognized with roentgenogram. As histopathological findings, increase of fat marrow, decrease of bone trabeculae, and its marked degeneration were recognized. Proliferation of some blood vessels was found out, but thickness of the internal membrane and thrombogenesis were not recognized. Treatment should be performed according to degree of displacement of fractures. In this case, artificial joint replacement surgery was performed to the side of fracture of this time, because this case was bilateral femoral neck fractures and the patient had received artificial head replacement surgery in the other side of fracture formerly.

    • Gorlin syndrome (GS, also known as nevoid basal cell carcinoma syndrome (NBCCS, is a rare inherited multisystem disorder. This paper presents a 22-years-old Iranian woman with this syndrome whose past history was multiple keratocysts of maxillary bone. She was referred to gynecology clinic with the chief complaint of irregular menses and vaginal spotting. On examination, frontal bossing and hypertelorism were detected. Physical examination of genitalia disclosed bilateral adnexal masses. Pelvic ultrasound showed two solid, echogenous and calcified masses measuring 100*50*10 & 60*50*45 mm in the left and right ovaries, respectively. The patient underwent right oophorectomy and ovarian mass resection with preservation of intact ovarian tissue on the left side. On frozen and permanent histological sections, bilateral and calcified ovarian fibromas were diagnosed. Surprisingly, during the last follow-up one year after the surgery, we found that our patient was expecting a baby. It can be concluded that in the presence of bilateral and calcified ovarian fibromas, the possibility of GS should be considered. Accurate diagnosis is only possible with close attention to the familial and past medical history and physical examination. In these patients, careful follow up for detecting malignancies and other complications is highly recommended.

    We describe the case of a 30-year-old man who developed chronic bilateral shoulder pain that relapsed and remitted over the course of 1 year. The patient was diagnosed with congenital shoulder fusion anomalies. The right shoulder showed anomalous accessory articulation between the distal third of the clavicle and the acromion along with normal articulation of the shoulder on CT. At the left shoulder, bony fusions were present between the distal portion of the clavicle, the acromion, and the coracoid process, and between the coracoid process, upper portion of the glenoid, and upper body of the scapula, which formed a bony canal and was responsible for hypoplasia of the supraspinatus muscle on CT and MRI. To our knowledge, this is the first description of such congenital shoulder anomalies with extreme bony fusion and is an illustrative example of how imaging may be used to differentiate fusion from other congenital abnormalities of the shoulder to aid diagnosis.

    Full Text Available We report the occurrence of a bilateral pneumothoraces after unilateral central venous catheterization of the right subclavian vein in a 70-year-old patient. The patient had no history of pulmonary or pleural disease and no history of cardiothoracic surgery. Two days earlier, she had a median laparotomy under general and epidural anaesthesia. Prior to the procedure, the patient was hemodynamically stable and her transcutaneous oxygen saturation was 97% in room air. We punctured the right pleural space before cannulation of the right subclavian vein. After the procedure, the patient slowly became hemodynamically instable with respiratory distress. A chest radiograph revealed a complete left-side pneumothorax and a mild right-side pneumothorax. The right-side pneumothorax became under tension after left chest tube insertion. The symptoms finally resolved after insertion of a right chest tube. After a diagnostic work-up, we suspect a congenital “Buffalo chests” explaining bilateral pneumothoraces and a secondary tension pneumothorax.

    Pneumothorax is a possible complication of tracheostomy. We report a rare case of bilateral pneumothoraces resulting from tracheostomy in an advanced laryngeal cancer patient. A 59-year-old man was referred to our clinic for evaluation and treatment of laryngeal tumor. Laryngeal endoscopy showed limited movement of bilateral vocal cords, and computed tomography revealed a tumor lesion extending from the vocal cords to the subglottic area. Three days after the first visit, the patient developed respiratory difficulty, and we elected to perform emergency tracheostomy for airway management. Immediately after the start of the procedure, he began hyperventilating, and complained of respiratory discomfort and chest pain. We then recognized a mediastinal air leak, and we suspected pneumothorax resulting from the tracheostomy. Chest X-ray showed bilateral pneumothoraces; therefore, we inserted bilateral chest drainage tubes, which stabilized his respiratory condition. We speculated that the pathogenesis of the bilateral pneumothoraces was weakened alveolar walls secondary to long-term smoking, and a significant rise in airway pressure because of airway constriction by the neck-extended position and hyperventilation, during tracheostomy.

Juvenile myelomonocytic leukemia is a rare myelodysplastic syndrome that typically presents in boys younger than 3 years of age with splenomegaly, lymphadenopathy and skin findings. Bilateral breast masses in a child are rare and, as such, present a diagnostic dilemma due to the relative paucity of cases in the literature. We present a case of granulocytic sarcoma of the breasts in a patient with juvenile myelomonocytic leukemia. The authors hope that increased reporting and research regarding pediatric breast masses will help create awareness for such cases. (orig.)

  9. Intrinsic default mode network connectivity predicts spontaneous verbal descriptions of autobiographical memories during social processing

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Neural systems activated in a coordinated way during rest, known as the default mode network (DMN, also support autobiographical memory (AM retrieval and social processing/mentalizing. However, little is known about how individual variability in reliance on personal memories during social processing relates to individual differences in DMN functioning during rest (intrinsic functional connectivity. Here we examined 18 participants’ spontaneous descriptions of autobiographical memories during a two-hour, private, open-ended interview in which they reacted to a series of true stories about real people’s social situations and responded to the prompt, how does this person’s story make you feel? We classified these descriptions as either containing factual information (semantic AMs or more elaborate descriptions of emotionally meaningful events (episodic AMs. We also collected resting state fMRI scans from the participants and related individual differences in frequency of described AMs to participants’ intrinsic functional connectivity within regions of the DMN. We found that producing more descriptions of either memory type correlated with stronger intrinsic connectivity in the parahippocampal and middle temporal gyri. Additionally, episodic AM descriptions correlated with connectivity in the bilateral hippocampi and medial prefrontal cortex, and semantic memory descriptions correlated with connectivity in right inferior lateral parietal cortex. These findings suggest that in individuals who naturally invoke more memories during social processing, brain regions involved in memory retrieval and self/social processing are more strongly coupled to the DMN during rest.

    A case of radiation-induced bilateral common carotid artery stenosis is reported. This 60 years old housewife was hospitalized in 1982 because of sudden onset of mild left hemiparesis. Twenty-five years ago, she underwent radiation therapy of approximately 5,000 rads to the anterior cervical region because of thyroid cancer. Angiograms in 1982 revealed bilateral common carotid artery stenosis, especially in the right common carotid artery, the legion of which were included within the field of radiation performed in 1952. Right thromboendarterectomy was performed in 1983. At operation, slight periarterial fibrosis with calcified arteriosclerotic change was found, and dissection between the thickened intima and the media was not so difficult. Histological change of resected thromboendarterium was similar to the one observed in the pure arteriosclerotic disease. (author)

    Children with unilateral cochlear implants (CIs) may have delayed vocabulary development for an extended period after implantation. Bilateral cochlear implantation is reported to be associated with improved sound localization and enhanced speech perception in noise. This study proposed that bilateral implantation might also promote early vocabulary development. Knowledge regarding vocabulary growth and composition in children with bilateral CIs and factors associated with it may lead to improvements in the content of early speech and language intervention and family counselling. To analyse the growth of early vocabulary and its composition during the first year after CI activation and to investigate factors associated with vocabulary growth. The participants were 20 children with bilateral CIs (12 boys; eight girls; mean age at CI activation = 12.9 months). Vocabulary size was assessed with the Finnish version of the MacArthur Communicative Development Inventories (CDI) Infant Form and compared with normative data. Vocabulary composition was analysed in relation to vocabulary size. Growth curve modelling was implemented using a linear mixed model to analyse the effects of the following variables on early vocabulary growth: time, gender, maternal education, residual hearing with hearing aids, age at first hearing aid fitting and age at CI activation. Despite clear vocabulary growth over time, children with bilateral CIs lagged behind their age norms in receptive vocabulary during the first 12 months after CI activation. In expressive vocabulary, 35% of the children were able to catch up with their age norms, but 55% of the children lagged behind them. In receptive and expressive vocabularies of 1-20 words, analysis of different semantic categories indicated that social terms constituted the highest proportion. Nouns constituted the highest proportion in vocabularies of 101-400 words. The proportion of verbs remained below 20% and the proportion of function words and

  17. Status of safety issues at licensed power plants: TMI Action Plan requirements; unresolved safety issues; generic safety issues; other multiplant action issues

    International Nuclear Information System (INIS)

    1993-12-01

    As part of ongoing US Nuclear Regulatory Commission (NRC) efforts to ensure the quality and accountability of safety issue information, the NRC established a program for publishing an annual report on the status of licensee implementation and NRC verification of safety issues in major NRC requirements areas. This information was initially compiled and reported in three NUREG-series volumes. Volume 1, published in March 1991, addressed the status of Three Mile Island (TMI) Action Plan Requirements. Volume 2, published in May 1991, addressed the status of unresolved safety issues (USIs). Volume 3, published in June 1991, addressed the implementation and verification status of generic safety issues (GSIs). The first annual supplement, which combined these volumes into a single report and presented updated information as of September 30, 1991, was published in December 1991. The second annual supplement, which provided updated information as of September 30, 1992, was published in December 1992. Supplement 2 also provided the status of licensee implementation and NRC verification of other multiplant action (MPA) issues not related to TMI Action Plan requirements, USIs, or GSIs. This third annual NUREG report, Supplement 3, presents updated information as of September 30, 1993. This report gives a comprehensive description of the implementation and verification status of TMI Action Plan requirements, safety issues designated as USIs, GSIs, and other MPAs that have been resolved and involve implementation of an action or actions by licensees. This report makes the information available to other interested parties, including the public. Additionally, this report serves as a follow-on to NUREG-0933, ''A Prioritization of Generic Safety Issues,'' which tracks safety issues until requirements are approved for imposition at licensed plants or until the NRC issues a request for action by licensees

    Since being approved in 2009, bilateral simultaneous cochlear implantation (CI) has been the standard treatment for children in the UK who meet the criteria for CI. The aim was to report surgical outcomes of bilateral CI in the UK. Between January 2010 and December 2011, 14 UK CI centres collected data prospectively: demographics, aetiology, use of imaging, device type, surgery duration, use of intra-operative electrophysiology, length of stay, and post-operative complications. 1397 CI procedures in 961 CI recipients were included; 436 bilateral simultaneous, 394 bilateral sequential, and 131 unilateral. The majority (85%) were congenitally deaf. The commonest causes of acquired deafness were meningitis and cytomegalovirus infection. The median age for congenitally deaf bilateral simultaneous CI was 2.2 years, mean surgical duration 4.5 hours. 6.3% surgeries were day case procedures. Eight cases (2.0%) of planned bilateral CI had unilateral surgery. The overall major complication rate was 1.6% (0.9% excluding device failures), including explantation due to infection (0.2%), cerebrospinal fluid leak (0.2%), and meningitis (0.1%). There were no permanent facial nerve palsies and no deaths. Sixty-two (6.5%) immediate minor complications included 12 (1.3%) children with significant vestibular impairment. The complication rate was similar following bilateral CI compared to sequential and unilateral CI, and is comparable to other published series. This prospective multi-centre audit provides evidence that bilateral paediatric CI is a safe procedure in the UK, thus endorsing its role as a major therapeutic intervention in childhood deafness.

  19. Bilateral carotid body tumor resection in a female patient

    Directory of Open Access Journals (Sweden)

    Alfred Burgess

    Full Text Available Introduction: Carotid body tumors also called carotid paragangliomas are rare neuroendocrine neoplasms derived from neural crest cells, approximately 3% of all paragangliomas occur in the head and neck area (Xiao and She, 2015; although they represent 65% of the head and neck paragangliomas (Georgiadis et al., 2008. Presentation of case: We present the therapeutic management of a 65-year-old woman with bilateral carotid body tumors. The patient presented to medical clinic for unrelated signs and symptoms of weight loss, dyspepsia, and epigastric pain. Physical examination showed bilateral non-tender neck masses for which imaging studies were ordered resulting in the diagnosis of bilateral carotid tumor. Surgical resection was staged with one week of distance between each tumor resection. Discussion: Carotid Body Tumors can arise from the paraganglia located within the adventitia of the medial aspect of the carotid bifurcation.Resection is the only curative treatment. Carotid body tumors resection represents a special challenge due to potential neurovascular complications. Conclusions: Surgical resection of carotid body tumors represents a special challenge to the surgeon because of the complex anatomical location of the tumor, including close relationship with the cranial nerves, involvement of the carotid vessels and large vascularization of the tumor. With the advance of diagnosis and improvement in surgical techniques as well as the understanding of biological behavior of tumors, surgical treatment has become a safer alternative for treating these tumors.

    2010-04-01

    The purpose of this study was to review our surgical experience with patients with bilateral combined anterior and posterior persistent fetal vasculature syndrome (PFVS). We retrospectively reviewed the charts of all patients seen in our tertiary care pediatric retinal practice from 1988 to 2008 with a potential diagnosis of bilateral PFVS with posterior involvement. Clinical diagnosis required the presence of either bilateral persistent hyaloidal stalk tissue with retinal involvement or bilateral dense retrolental fibrovascular plaques (usually with no posterior view preoperatively) without a family history or genetic testing consistent with Norrie disease or familial exudative vitreoretinopathy. Chart review showed 22 vitrectomized patients with clinical findings consistent with bilateral PFVS with posterior involvement who did not have a family history or genetic testing consistent with Norrie disease or familial exudative vitreoretinopathy. All 22 of these patients with posterior retinal involvement also had anterior findings and thus can be classified as combined anterior and posterior PFVS. Of the 13 patients with visual acuity follow-up data, 9 patients (69%) maintained at least light perception vision in at least 1 eye at last follow-up. Of the 28 operated eyes in 16 patients with follow-up data, 3 eyes (11%) were phthisical at last follow-up. Children with bilateral PFVS with posterior retinal involvement have a dismal visual prognosis if left unoperated. In this relatively large series of a rare condition, we find that vitrectomy with or without lensectomy is beneficial in bilateral combined anterior and posterior PFVS in two regards: maintenance or restoration of vision and avoidance of phthisis bulbi.

  1. Idiopathic Bilateral External Jugular Vein Thrombosis.

    Science.gov (United States)

    Hindi, Zakaria; Fadhel, Ehab

    2015-08-20

    Vein thrombosis is mainly determined by 3 factors, which constitute a triad called Virchow's triad: hypercoagulability, stasis, and endothelial injury. Venous thrombosis commonly occurs in the lower extremities since most of the blood resides there and flows against gravity. The veins of the lower extremities are dependent on intact valves and fully functional leg muscles. However, in case of valvular incompetency or muscular weakness, thrombosis and blood stasis will occur as a result. In contrast, the veins of the neck, specially the jugulars, have distensible walls which allow flexibility during respiration. In addition, the blood directly flows downward towards the heart. Nevertheless, many case reports mentioned the thrombosis of internal jugular veins and external jugular veins with identified risk factors. Jugular vein thrombosis has previously been associated in the literature with a variety of medical conditions, including malignancy. This report is of a case of idiopathic bilateral external jugular vein thrombosis in a 21 year-old male construction worker of Southeast Asian origin with no previous medical history who presented with bilateral facial puffiness of gradual onset over 1 month. Doppler ultrasound and computed tomography were used in the diagnosis. Further work-up showed no evidence of infection or neoplasia. The patient was eventually discharged on warfarin. The patient was assessed after 6 months and his symptoms had resolved completely. Bilateral idiopathic external jugular veins thrombosis is extremely rare and can be an indicator of early malignancy or hidden infection. While previous reports in the literature have associated jugular vein thrombosis with malignancy, the present case shows that external jugular vein thrombosis can also be found in persons without malignancy.

  2. Bilateral cleft lip nasal deformity

    Full Text Available Bilateral cleft lip nose deformity is a multi-factorial and complex deformity which tends to aggravate with growth of the child, if not attended surgically. The goals of primary bilateral cleft lip nose surgery are, closure of the nasal floor and sill, lengthening of the columella, repositioning of the alar base, achieving nasal tip projection, repositioning of the lower lateral cartilages, and reorienting the nares from horizontal to oblique position. The multiplicity of procedures in the literature for correction of this deformity alludes to the fact that no single procedure is entirely effective. The timing for surgical intervention and its extent varies considerably. Early surgery on cartilage may adversely affect growth and development; at the same time, allowing the cartilage to grow in an abnormal position and contributing to aggravation of deformity. Some surgeons advocate correction of deformity at an early age. However, others like the cartilages to grow and mature before going in for surgery. With peer pressure also becoming an important consideration during the teens, the current trend is towards early intervention. There is no unanimity in the extent of nasal dissection to be done at the time of primary lip repair. While many perform limited nasal dissection for the fear of growth retardation, others opt for full cartilage correction at the time of primary surgery itself. The value of naso-alveolar moulding (NAM too is not universally accepted and has now more opponents than proponents. Also most centres in the developing world have neither the personnel nor the facilities for the same. The secondary cleft nasal deformity is variable and is affected by the extent of the original abnormality, any prior surgeries performed and alteration due to nasal growth. This article reviews the currently popular methods for correction of nasal deformity associated with bilateral cleft lip, it′s management both at the time of cleft lip repair

    1994-02-01

    Pacific Northwest Laboratory has prepared this report under the direction of Westinghouse Hanford Company. The report provides an integrated description of the system planned for managing Hanford's solid low-level waste, low-level mixed waste, transuranic waste, and transuranic mixed waste. The primary purpose of this document is to illustrate a collective view of the key functions planned at the Hanford Site to handle existing waste inventories, as well as solid wastes that will be generated in the future. By viewing this system as a whole rather than as individual projects, key facility interactions and requirements are identified and a better understanding of the overall system may be gained. The system is described so as to form a basis for modeling the system at various levels of detail. Model results provide insight into issues such as facility capacity requirements, alternative system operating strategies, and impacts of system changes (ie., startup dates). This description of the planned Hanford solid waste processing system: defines a baseline system configuration; identifies the entering waste streams to be managed within the system; identifies basic system functions and waste flows; and highlights system constraints. This system description will evolve and be revised as issues are resolved, planning decisions are made, additional data are collected, and assumptions are tested and changed. Out of necessity, this document will also be revised and updated so that a documented system description, which reflects current system planning, is always available for use by engineers and managers. It does not provide any results generated from the many alternatives that will be modeled in the course of analyzing solid waste disposal options; such results will be provided in separate documents

    2001-01-01

    A new approach to designing bilateral power transaction bargaining models between two independent utilities in a deregulated electricity market is proposed. In the paper it is assumed that each utility (a seller or a buyer) knows its own operating costs but does not know those of its opponent. The bilateral power transaction problem is then considered as non-cooperative bargaining under incomplete information. Each participant develops its own bargaining strategy based on estimates of the opponent's operating costs and bargaining strategy. Two bargaining models are developed and examples are employed for demonstration. (Author)

    2015-04-01

    Full Text Available Bilateral acute iris transillumination (BAIT is a relatively new clinical entity characterized by bilateral acute loss of iris pigment epithelium, iris transillumination, pigment dispersion in the anterior chamber, and sphincter paralysis. We report the case of a 30-year-old male who was initially diagnosed with acute iridocyclitis in a different clinic and treated with topical and systemic corticosteroids. He was referred to our clinic to seek another opinion because his symptoms did not improve. An ocular examination revealed bilateral pigment dispersion into the anterior chamber, diffuse iris transillumination, pigment dusting on the anterior lens capsule, atonic and distorted pupils, and increased intraocular pressure, suggesting a diagnosis of BAIT rather than iridocyclitis. Clinicians should be aware of the differential diagnosis of syndromes associated with pigment dispersion from iridocyclitis to avoid aggressive anti-inflammatory therapy and detailed investigation for uveitis.

    The management of acute scrotal swelling can be challenging in neonatal age, with scrotal infections being great mimickers of testicular torsion. Only a few unilateral cases of scrotal abscess have been previously reported, mostly caused by Staphylococcus and Salmonella. We describe the case of a newborn who developed bilateral scrotal abscesses caused by Klebsiella pneumoniae and discuss the rarity of the case, regarding both the bilaterality and the pathogen, never reported before.

    Arthroscopic repair of rotator cuff tears is a common procedure performed by orthopedic surgeons. There is a well-known incidence of up to 35% of bilateral rotator cuff tear disease in patients who have a known unilateral tear. The majority of the literature focuses on outcomes after unilateral surgery. The purpose of this study was to determine if there are clinical differences in shoulders of patients who underwent staged bilateral rotator cuff repairs during their lifetime. A retrospective review of all patients who underwent staged bilateral arthroscopic rotator cuff surgery at our institution was performed. All patients had at least 2 years of follow-up. Clinical outcome scores including the American Shoulder and Elbow Surgeons (ASES), Single Assessment Numeric Evaluation, and Rowe measures were obtained. A subset of patients returned for clinical and ultrasound evaluation performed by an independent fellowship-trained musculoskeletal radiologist. Overall, 110 shoulders in 55 patients, representing 68% of all eligible patients, participated. No clinical or statistical difference was found in any outcome measure. ASES scores averaged 86.5 (36.7-100) in the dominant shoulder compared with 89.6 (23.3-100) in the nondominant shoulder (P = .42). Ultrasound was available on 34 shoulders and showed complete healing rate of 88%. The shoulders with retearing of the rotator cuff (12%) demonstrated clinically relevant lower ASES scores (72.5) compared with shoulders with confirmed healed repairs (86.2; P = .2). Patients who undergo staged bilateral rotator cuff repair can expect to have similarly good clinical outcomes regardless of hand dominance or chronologic incidence with excellent healing rates in both shoulders.

    2011-01-01

    This is a case of a 2-year-old boy with sickle cell disease who presented with bilateral eyelid swelling, limited extraocular motility, and lateral subperiosteal fluid collection associated with bilateral lateral orbital wall infarctions on MRI. The patient was managed medically with intravenous fluids, analgesics, broad-spectrum antibiotics, systemic steroids, and clinically improved. Patients with sickle cell disease are susceptible to infarction of the orbital bones during vaso-occlusive crises. Orbital wall infarction can lead to acute proptosis and restricted extraocular motility. Orbital wall infarction should be considered in sickle cell patients with orbital diseases so that appropriate treatment can be instituted promptly to prevent the serious sequelae of orbital compression syndrome.

    2012-01-01

    Full Text Available A 13-year-old female patient reported with the chief complaint of irregular front teeth. She had a skeletal Class III and Angle′s Class I malocclusion with hyperdivergent growth pattern and bilateral impaction of maxillary canines. Surgical exposure of the impacted teeth and orthodontic alignment was planned. The surgical exposure was done by a minimally invasive modified window technique. Orthodontic treatment of impacted canines without causing significant morbidity to the adjacent teeth and periodontium is a challenge. The bilaterally impacted maxillary canines were successfully aligned and leveled. The depth of the gingival sulcus and clinical crown heights of disimpacted teeth were normal post-treatment and after 1 year of retention.

  13. Availability of binaural cues for pediatric bilateral cochlear implant recipients.

    2015-03-01

    Bilateral implant recipients theoretically have access to binaural cues. Research in postlingually deafened adults with cochlear implants (CIs) indicates minimal evidence for true binaural hearing. Congenitally deafened children who experience spatial hearing with bilateral CIs, however, might perceive binaural cues in the CI signal differently. There is limited research examining binaural hearing in children with CIs, and the few published studies are limited by the use of unrealistic speech stimuli and background noise. The purposes of this study were to (1) replicate our previous study of binaural hearing in postlingually deafened adults with AzBio sentences in prelingually deafened children with the pediatric version of the AzBio sentences, and (2) replicate previous studies of binaural hearing in children with CIs using more open-set sentences and more realistic background noise (i.e., multitalker babble). The study was a within-participant, repeated-measures design. The study sample consisted of 14 children with bilateral CIs with at least 25 mo of listening experience. Speech recognition was assessed using sentences presented in multitalker babble at a fixed signal-to-noise ratio. Test conditions included speech at 0° with noise presented at 0° (S0N0), on the side of the first CI (90° or 270°) (S0N1stCI), and on the side of the second CI (S0N2ndCI) as well as speech presented at 0° with noise presented semidiffusely from eight speakers at 45° intervals. Estimates of summation, head shadow, squelch, and spatial release from masking were calculated. Results of test conditions commonly reported in the literature (S0N0, S0N1stCI, S0N2ndCI) are consistent with results from previous research in adults and children with bilateral CIs, showing minimal summation and squelch but typical head shadow and spatial release from masking. However, bilateral benefit over the better CI with speech at 0° was much larger with semidiffuse noise. Congenitally deafened

    1985-02-01

    Round, well-demarcated, symmetrical low densities in a bilateral thalamus in a case of descending transtentorial herniation due secondarily to acute traumatic left subdural hematoma are reported. An 8-year-old boy, on whom emergency surgery was refused by his parents, showed a marked shift due to the hematoma on admission; this was followed by a low density in the left PCA territory and round, equivocal hypodensities in the anterior thalamus 44 hours post-trauma. The equivocal hypodensities became definite, well-demarcated, round low densities situated symmetrically in the anterior thalamus on the 39th day post-trauma. Akinetic mutism was noted at this time. The symmetrical low densities and the PCA-territory low density persisted as late as the 39th day post-trauma, suggesting infarcts. The downward stretch of the bilateral thalamoperforators, which was effected by a narrowing of the interpeduncular fossa with an approximation of the bilateral perforators, plus a downward shift of the PCA due to descending transtentorial herniation, was assumed to be the mechanism involved.

  16. Bilateral theta-burst TMS to influence global gestalt perception.

    Directory of Open Access Journals (Sweden)

    Bernd Ritzinger

    Full Text Available While early and higher visual areas along the ventral visual pathway in the inferotemporal cortex are critical for the recognition of individual objects, the neural representation of human perception of complex global visual scenes remains under debate. Stroke patients with a selective deficit in the perception of a complex global Gestalt with intact recognition of individual objects - a deficit termed simultanagnosia - greatly helped to study this question. Interestingly, simultanagnosia typically results from bilateral lesions of the temporo-parietal junction (TPJ. The present study aimed to verify the relevance of this area for human global Gestalt perception. We applied continuous theta-burst TMS either unilaterally (left or right or bilateral simultaneously over TPJ. Healthy subjects were presented with hierarchically organized visual stimuli that allowed parametrical degrading of the object at the global level. Identification of the global Gestalt was significantly modulated only for the bilateral TPJ stimulation condition. Our results strengthen the view that global Gestalt perception in the human brain involves TPJ and is co-dependent on both hemispheres.

    1990-01-01

    Three patients developed bilateral breast cancer at 10 to 24 years after mantle irradiation for locally or systemically advanced Hodgkin's disease (HD). Four of the six cancers in the three patients were detected only by mammography. Pathologically, five of the cancers were intraductal carcinomas (four with an invasive component) with one being a lobular carcinoma. Five of the six lesions were Stage I pathologically without evidence of axillary nodal involvement. It is recommended that female patients with Hodgkin's disease who have received mantle irradiation as part of the therapy for their Hodgkin's disease and who are observed for 10 or more years after completion of mantle irradiation be considered at risk for the development of breast cancer. Such patients should be monitored appropriately by routine bilateral mammograms to increase the early detection of early stage lesions

    We report the case of a 75-year-old woman who developed an acute bilateral angle-closure associated with choroidal effusion a day after an uneventful cataract surgery. The same patient had undergone a similarly uneventful cataract surgery two weeks before, under the same protocol, with no postoperative complication in the other eye. Medical treatment, including the use of oral sulfamide-related drugs (acetazolamide), topical beta-blockers and steroids led to a gradual decrease in intraocular pressure (IOP) and choroidal effusion. Despite initial reports suggesting a link between sulfamide-exposure and these rare forms of angle-closure, our report would suggest a more complex pathophysiology behind this intriguing phenomenon.

    Our ability to reason by analogy facilitates problem solving and allows us to communicate ideas efficiently. In this study, we examined the neural correlates of analogical reasoning and, more specifically, the contribution of rostrolateral prefrontal cortex (RLPFC) to reasoning. This area of the brain has been hypothesized to integrate relational information, as in analogy, or the outcomes of subgoals, as in multi-tasking and complex problem solving. Using fMRI, we compared visuospatial analogical reasoning to a control task that was as complex and difficult as the analogies and required the coordination of subgoals but not the integration of relations. We found that analogical reasoning more strongly activated bilateral RLPFC, suggesting that anterior prefrontal cortex is preferentially recruited by the integration of relational knowledge. Consistent with the need for inhibition during analogy, bilateral, and particularly right, inferior frontal gyri were also more active during analogy. Finally, greater activity in bilateral inferior parietal cortex during the analogy task is consistent with recent evidence for the neural basis of spatial relation knowledge. Together, these findings indicate that a network of frontoparietal areas underlies analogical reasoning; we also suggest that hemispheric differences may emerge depending on the visuospatial or verbal/semantic nature of the analogies.

    Full Text Available Bilateral acute depigmentation of the iris (BADI is a recently described entity characterized by acute onset of pigment dispersion in the anterior chamber, depigmentation of the iris, and heavy pigment deposition in the anterior chamber angle. Involvement is always bilateral, simultaneous, and symmetrical. We report the case of a 61-year-old man who presented with bilateral ocular pain, red eyes, and severe photophobia. Examination revealed a dense Krukenberg spindle, heavy pigment dispersion in the anterior chamber, extensive transillumination iris defects, and a heavy pigment deposition in the trabecular meshwork bilaterally. Intraocular pressure increased to 48 mmHg in both eyes. The patient received topical steroids, maximum hypotensive treatment and oral valacyclovir. Intraocular pressure gradually decreased throughout the second and third months, and medications were gradually tapered. The time to complete resolution of pigment dispersion was 18 weeks. Visual acuity and visual fields remained normal, but the photophobia was permanent.

    Full Text Available ABSTRACT Bilateral stress fracture of femoral neck in healthy young patients is an extremely rare entity, whose diagnostic and treatment represent a major challenge. Patients with history of hip pain, even non-athletes or military recruits, should be analyzed to achieve an early diagnosis and prevent possible complications from the surgical treatment. This report describes a 43-year-old male patient, non-athlete, without previous diseases, who developed bilateral stress fracture of femoral neck without displacement. He had a late diagnosis; bilateral osteosynthesis was made using cannulated screws. Although the diagnosis was delayed in this case, the study highlights the importance of the diagnosis of stress fracture, regardless of the activity level of the patients, for the success of the treatment.

    Single nucleotide polymorphism (SNP), rs11200638, in the promoter of HTRA1 has recently been shown to increase the risk for AMD. In order to investigate the association of this HTRA1 polymorphism and the bilaterality of AMD, we genotyped rs11200638 in control, unilateral, and bilateral advanced AMD patients. The A allele for SNP rs11200638 in HTRA1, was significantly more prevalent in bilateral wet AMD and GA patients than in unilateral groups (p=.02 and p=.03, respectively). The homozygote odds ratios of bilateral wet AMD and GA are significantly greater than those seen in unilateral groups (twofold and threefold increase, respectively). This finding is consistent with the role of HTRA1 in AMD pathogenesis and will help aid in the clinical management and prognosis of AMD patients.

    This paper proposes a new method for secure bilateral transactions determination ensuring economic power dispatch of the generators using new AC distribution factors for pool and bilateral coordinated markets. The new optimization problem considers simultaneous minimization of deviations from scheduled transactions and fuel cost of the generators in the network. The fuel cost has been obtained for hybrid market model and impact of different percentage of bilateral demand on fuel cost, generation share, and pattern of transactions has also been determined. The impact of optimally located unified power flow controller (UPFC) on the bilateral transactions, fuel cost and generation pattern has also been studied. The results have also been obtained for pool market model. The proposed technique has been applied on IEEE 24-bus reliability test system (RTS). (author)

    To report a rare case of simultaneous bilateral cochlear implantation in a five-month-old child with Usher syndrome. Case report. A five-month-old boy with Usher syndrome and congenital profound bilateral deafness underwent simultaneous bilateral cochlear implantation. The decision to perform implantation in such a young child was based on his having a supportive family and the desire to foster his audiological development before his vision deteriorated. The subject experienced easily resolvable intra- and post-operative adverse events, and was first fitted with an externally worn audio processor four weeks after implantation. At 14 months of age, his audiological development was age-appropriate. Simultaneous bilateral cochlear implantation is possible, and even advisable, in children as young as five months old when performed by an experienced implantation team.

  11. Congestion rents and FTR evaluations in mixed-pool-bilateral systems

    Liu, Minghai; Gross, George

    2008-01-01

    Evaluation of key metrics for congestion management, including the congestion rents and the financial transmission rights (FTR) payoffs, requires the efficient allocation of transmission services and the calculation of appropriate locational marginal prices (LMPs). This requirement is particularly acute when there are bilateral transactions coexisting with the centralized pool markets. We propose a new formulation for this purpose, which captures explicitly the contribution of the bilateral transactions to the social welfare. The proposed formulation effectively integrates the pool market and the bilateral transactions on a consistent basis and results in the more efficient allocation of the transmission resources than the conventional tool. We assess analytically the capabilities of the proposed formulation and solution and quantify the improvements in the evaluations over those done using the conventional approach. Such improvements are also illustrated using simulation results on a wide range of test systems including the IEEE 118-bus network. (author)

  12. BILGO: Bilateral greedy optimization for large scale semidefinite programming

    Hao, Zhifeng; Yuan, Ganzhao; Ghanem, Bernard

    2013-01-01

    Many machine learning tasks (e.g. metric and manifold learning problems) can be formulated as convex semidefinite programs. To enable the application of these tasks on a large-scale, scalability and computational efficiency are considered as desirable properties for a practical semidefinite programming algorithm. In this paper, we theoretically analyze a new bilateral greedy optimization (denoted BILGO) strategy in solving general semidefinite programs on large-scale datasets. As compared to existing methods, BILGO employs a bilateral search strategy during each optimization iteration. In such an iteration, the current semidefinite matrix solution is updated as a bilateral linear combination of the previous solution and a suitable rank-1 matrix, which can be efficiently computed from the leading eigenvector of the descent direction at this iteration. By optimizing for the coefficients of the bilateral combination, BILGO reduces the cost function in every iteration until the KKT conditions are fully satisfied, thus, it tends to converge to a global optimum. In fact, we prove that BILGO converges to the global optimal solution at a rate of O(1/k), where k is the iteration counter. The algorithm thus successfully combines the efficiency of conventional rank-1 update algorithms and the effectiveness of gradient descent. Moreover, BILGO can be easily extended to handle low rank constraints. To validate the effectiveness and efficiency of BILGO, we apply it to two important machine learning tasks, namely Mahalanobis metric learning and maximum variance unfolding. Extensive experimental results clearly demonstrate that BILGO can solve large-scale semidefinite programs efficiently.

    A new method for measuring the depth of the parasternal lymph node was studied. The bilateral collimator used in this study consisted of two arrays of parallel holes which were slanted at +-30 degrees, respectively, to the vertical line. When the collimator was set to image the object in both sides of the field, the object and the dual images formed a regular triangle. The distance (D) from the image (crystal) plane to the object can be expressed by the equation: D = 1/2.L.cot30 0 = 0.866.L where L is the interval between the dual images calibrated to the real length. The distance from the collimator surface to the object is obtained by subtracting the effective thickness (T) between the image plane and the collimator surface from D. T was experimentally measured by the above equation, placing point sources on the collimator surface. The principle was applied to measure the depth of the parasternal lymph node. The parasternal lymphoscintigram was obtained four hours after bilateral subcostal injection of sup(99m)Tc-sulfur colloid and the image was taken by a Searle Pho/Gamma LFOV camera equipped with the bilateral collimator. When the scintigraphic image was made, radioactive markers were placed at the body surface to measure the distance from the collimator surface to the body surface Nineteen patients were examined. As a result, the lymph nodes were found to be located in the depths ranging widely from 0.4 to 6.5 cm from the anterior surface of the chest wall. These lymph nodes were thought to contain the deeply seated mediastinal nodes, and the superficial nodes located directly beneath the skin. Model studies were also performed to estimate the accuracy of this method and satisfactory results were obtained. (author)

    This case report describes an unexpected event that took place as a result of using improvised equipment. The patient, a 16-year-old female undergoing complex oral surgery, suffered bilateral pneumothorax following the improper use of an airway support device. During the immediate postoperative period with the patient still intubated, oxygen tubing was attached to a right angle elbow connector with the port closed and 10 L/minute oxygen flow was administered to the patient in a manner that did not allow the patient to exhale. Within seconds, pneumothorax was apparent as the patient's vital signs deteriorated, visible swelling was noted in the shoulders and neck, and there was an absence of breath sounds on auscultation. This case study has application beyond the immediate discussion of bilateral pneumothorax, serving as a caution about the unintended consequences of equipment improvisation. In addition to highlighting the hazards of providing patient care with a non-standard device, this study also provides a powerful example of the human factors that can contribute to medical errors in the healthcare setting.

    Full Text Available Microspherophakia is rare bilateral congenital anamoly of the crystalline lens. The condition may be isolated , familial or it may be associated with systemic affections like Marfan's syndrome , Weil - Marchesani syndrome , hyperlysinemia and congenital rubella. Microspherophakia results in lenticular myopia , lens dislocation , usually inferiorly and inverse glaucoma. We present a case in a 8 year old child who presented with bilateral microspherophakia and anterior dislocation of lens of right eye. visual acuity in right eye was counting fingers close to face and i n left eye 6/60.IOP with perkins applanation tonometer was 30mmHg in right eye 22mmHg in left eye , cornea was hazy due to edema , anterior chamber was shallow in both eye patient was managed with emergency lens extraction of right eye and secondary ACIOL im plantation. Left eye was managed by laser peripheral iridotomy. IOP was within normal limits postoperatively in both eyes without any antiglaucoma medications. Postoperatively best corrected visual acuity in right was 6/18 and 6/9 in left eye.

    Full Text Available A 48-year-old woman sustained simultaneous isolated bilateral greater trochanteric fracture, following a road traffic accident. The patient presented to us 1 month after the injury. She presented with complaints of pain in the left hip and inability to walk. Roentgenograms revealed displaced comminuted bilateral greater trochanter fractures. The fracture of the left greater trochanter was reduced and fixed internally using the tension band wiring technique. The greater trochanter fracture on the right side was asymptomatic and was managed conservatively. The patient regained full range of motion and use of her hips after a postoperative follow-up of 6 months. Isolated fractures of the greater trochanter are unusual injuries. Because of their relative rarity and the unsettled controversy regarding their etiology and pathogenesis, several methods of treatment have been advocated. Furthermore, the reports of this particular type of injury are not plentiful and the average textbook coverage afforded to this entity is limited. In our study we discuss the mechanism of injury and the various treatment options available.

    Full Text Available A 51-year-old man with type 2 diabetes mellitus and chronic obstructive pulmonary disease presented to the emergency room with increasing bilateral leg pain, rash, and scrotal swelling with pain. Skin biopsy from his thigh revealed IgA-associated vasculitis. Due to hematuria, a renal biopsy was performed and showed an IgA glomerulonephritis with focal fibrinoid necrosis and neutrophil accumulation. Bilateral orchiectomies were performed in two separate procedures ten and thirteen days after the renal biopsy, as a result of uncontrolled abscess formation in testicles. Microscopically, both testicles revealed large abscess formation destroying almost the entire testicular parenchyma without tumor cells. Spermatic cord margins were further scrutinized microscopically to show bilateral vasculitis in many small size vessels, confirmed by positive endothelial staining for IgA. Some of the affected arteries revealed central organizing thrombi with recanalization features, highly suggestive of vasculitis-associated thrombi formation, resulting in testicular ischemic infarction and abscess formation. We conclude that this adult patient developed a severe form of Henoch-Schönlein purpura, with vasculitis affecting multiple organs, including the most serious and unusual complication of bilateral testicular infarction.

    Elastofibroma dorsi is a rare soft-tissue tumor of the chest wall and most commonly presents as a nontender mass adjacent to the inferior angle of the scapula. Its findings on CT and MRI generally lead to the diagnosis. We report a case of a 55-year-old woman with elastofibroma dorsi presenting with painless back mass. On sonography, it appeared as an ill-defined heterogeneous echogenic mass with internal streaky echostructures in bilateral subscapular regions. Excisional biopsy of the tumor was done and the tumor was confirmed as a bilateral elastofibroma dorsi by histopathologic examination.

    Full Text Available Bilateral femoral neck fractures are rare in the pediatric age group, and only a few cases have been reported following major trauma in children. A 9-year old girl presented with bilateral femoral neck fractures following a motor vehicle accident. The patient was managed with early operative fixation of the fractures with a successful outcome. This case highlights the importance of awareness of the occurrence of bilateral femoral neck fractures in the polytrauma patients. This case is presented due to its rarity.

    2018-04-01

    Full Text Available Tuberous sclerosis complex (TSC has several renal manifestations including angiomyolipomas (AML and renal epithelial neoplasms. A bilateral giant renal AML is extremely rare. We report a case of giant bilateral AML and discuss the diagnosis and treatment of it. The 22-year-old man was admitted due to bilateral flank pain, gross hematuria, and abdominal fullness. He had history of epilepsy, mental retardation, and delayed development during childhood. He had angiofibroma on his face since 10 years ago. Abdominal CT and MRI revealed large lobulated heterogeneous mass with fatty content. Based on those findings, we diagnosed the patient with bilateral giant renal AML. We gave conservative management for the patient and planned to total nephrectomy on the left kidney if the continued bleeding occurred. AML associated with TSC occur more frequently as multiple lesions and grows to larger size than idiopathic AML. Bilateral giant AML, which is very rare, could be treated with conservative management if no significant hemorrhage occurred.

    Two experiments are reported that investigate the effects of saccadic bilateral eye movements on the retrieval of item, associative, and contextual information. Experiment 1 compared the effects of bilateral versus vertical versus no eye movements on tests of item recognition, followed by remember-know responses and associative recognition. Supporting previous research, bilateral eye movements enhanced item recognition by increasing the hit rate and decreasing the false alarm rate. Analysis of remember-know responses indicated that eye movement effects were accompanied by increases in remember responses. The test of associative recognition found that bilateral eye movements increased correct responses to intact pairs and decreased false alarms to rearranged pairs. Experiment 2 assessed the effects of eye movements on the recall of intrinsic (color) and extrinsic (spatial location) context. Bilateral eye movements increased correct recall for both types of context. The results are discussed within the framework of dual-process models of memory and the possible neural underpinnings of these effects are considered.

    A method is proposed for calculation of PMSO frequency depending on succession of origination of polyneoplasias. The incidence rate of synchronous bilateral breast cancer (BC) was calculated in reference to all primary BC patients and came to 0.75%. The incidence rate of metachronous bilateral BC was calculated depending on the number of those BC patients having been registered every year of observation and it was found to be 5.4%. The total frequency of bilateral BC in a 20-year follow-up in the Crimean region appeared to be 6.15%. The incidence of metachronous bilateral BC was noted to be dependent on the length of follow-up: 1.27 percent and 4.14 percent in the 3- to 10- and 11- to 20-year periods respectively. The risk for the development of bilateral BC is conditioned by the time having elapsed since detection of the first tumor and increases after 10 and 18 years.

    A juvenile, male, yellow-eyed penguin (Megadyptes antipodes) with abnormal stance and decreased mobility was captured, held in captivity for approximately 6 weeks, and euthanized due to continued clinical signs. Radiographically, there was bilateral degenerative joint disease with coxofemoral periarticular osteophyte formation. Grossly, the bird had bilaterally distended, thickened coxofemoral joints with increased laxity, and small, roughened and angular femoral heads. Histologically, the left femoral articular cartilage and subchondral bone were absent, and the remaining femoral head consisted of trabecular bone overlain by fibrin and granulation tissue. There was no gross or histological evidence of infection. The historic, gross, radiographic, and histopathologic findings were most consistent with bilateral aseptic femoral head degeneration resulting in degenerative joint disease. Although the chronicity of the lesions masked the initiating cause, the probable underlying causes of aseptic bilateral femoral head degeneration in a young animal are osteonecrosis and osteochondrosis of the femoral head. To our knowledge, this is the first reported case of bilateral coxofemoral degenerative joint disease in a penguin.

    Full Text Available In the absence of syndromes, bilateral dentigerous cysts (DC located on the jaws are unusual. In English based language literature review, we only found eight reports of nonsyndromic bilateral dentigerous cyst associated with mandibular third molars. Therefore, we report the unusual occurrence of sizable nonsyndromic bilateral DC associated with mandibular impacted third molars in a 42-year-old Caucasian woman. The lesions were assessed by cone beam computed tomography (CBCT the right lesion showed approximately 23.64 mm and the left one, 16.57 mm diameter, both located intimately next to the mandibular canal. Bilateral surgical enucleation, related teeth excision of both third molars and plate for fixation placement on the right and bigger lesion, under general anesthesia was the final treatment choice. Clinical, radiographic and histopathological features confirmed diagnose of bilateral dentigerous cyst. Now-a-days, the patient is on 18 months radiograph follow-up with favorable osseous formation with no evidence of recurrence of the cysts.

A total of 8,172 injections were administered, among which 6,560 were unilateral and 1,612 were bilateral injections. Patients were included in the study regardless of the diagnosis. Ranibizumab and aflibercept were the antiangiogenic drugs used. The presence of endophthalmitis or retinal detachment was evaluated.Results: A total of 1 (0.012% culture-proven endophthalmitis and 19 (0.233% acute intraocular inflammations were registered. In the unilateral injections group, there were 18 (0.274% acute intraocular inflammations and 1 (0.015% culture-proven endophthalmitis. One (0.062% of the 1,612 bilateral same-day injections had a unilateral acute intraocular inflammation, and there were no culture-proven endophthalmitis in this group.Conclusion: Bilateral same-day injections are more convenient for patients and their caregivers than the unilateral injections administered on different days. In our study, the prevalence of culture-proven endophthalmitis and acute intraocular inflammation was lower in the bilateral injections than in the unilateral group. These data support the idea that bilateral same-day injections are a safe and valid treatment to use in our clinical practice.

    We study the determinants of China’s bilateral local currency swap lines that were established since the recent global finance crisis. It is found that economic factors, political considerations, and institutional characteristics including trade intensity, economic size, strategic partnership, free trade agreement, corruption, and stability affect the decision of signing a swap line agreement. Once a swap line agreement decision is made, the size of the swap line is then mainly affected by tr...

    Bilateral breast reconstructions are being increasingly performed. Autologous free-flap reconstructions represent the gold standard for post-mastectomy breast reconstruction but are resource intensive. This study aims to investigate the difference between hospital reimbursement and true cost of bilateral autologous free-flap reconstructions. Retrospective analysis of patients who underwent bilateral autologous free-flap reconstructions at a single Australian tertiary referral centre was performed. Hospital reimbursement was determined from coding analysis. A true cost analysis was also performed. Comparisons were made considering the effect of timing, indication and complications of the procedure. Forty-six bilateral autologous free-flap procedures were performed (87 deep inferior epigastric perforators (DIEPs), four superficial inferior epigastric artery perforator flaps (SIEAs) and one muscle-sparing free transverse rectus abdominis myocutaneous flap (MS-TRAM)). The mean funding discrepancy between hospital reimbursement and actual cost was $12,137 ± $8539 (mean ± standard deviation (SD)) (n = 46). Twenty-four per cent (n = 11) of the cases had been coded inaccurately. If these cases were excluded from analysis, the mean funding discrepancy per case was $9168 ± $7453 (n = 35). Minor and major complications significantly increased the true cost and funding discrepancy (p = 0.02). Bilateral free-flap breast reconstructions performed in Australian public hospitals result in a funding discrepancy. Failure to be economically viable threatens the provision of this procedure in the public system. Plastic surgeons and hospital managers need to adopt measures in order to make these gold-standard procedures cost neutral.

    We report a retrospective analysis of MRI in 206 patients with intractable seizures and describe the findings in bilateral mesial temporal sclerosis (MTS) on fast spin-echo (FSE) and fast fluid-attenuated inversion-recovery (fFLAIR) sequences. Criteria for MTS were atrophy, signal change and loss of the digitations of the head of the hippocampus. In patients with bilateral MRI signs of MTS, correlation with clinical electro, volumetric MRI data and neuropsychological tests, when available, was performed. Bilateral MTS was observed in seven patients. Bilateral loss of the digitations and signal change of fFLAIR was seen in all seven. In three, bilateral atrophy was obvious. In two patients, mild bilateral atrophy was observed and in two others, the hippocampi were: asymmetrical, with obvious atrophy on only one side. Volumetric data confirmed bilateral symmetrical atrophy in five patients, and volumes were at the lowest of the normal range in other two. The EEG showed temporal abnormalities in all patients, unilateral in five and bilateral in two. All patients had memory impairment and neuropsychological data confirmed visual and verbal memory deficits; two patients failed the Wada test on both sides. High-resolution T2-weighted FSE and fFLAIR sequences allow diagnosis of bilateral MTS, which has important therapeutic and prognostic implications. (orig.)

    1995-03-01

    We report a case of transient mutism and persistent auditory agnosia due to two successive ischemic infarcts mainly involving the insular cortex on both hemispheres. During the 'mutic' period, which lasted about 1 month, the patient did not respond to any auditory stimuli and made no effort to communicate. On follow-up examinations, language competences had re-appeared almost intact, but a massive auditory agnosia for non-verbal sounds was observed. From close inspection of lesion site, as determined with brain resonance imaging, and from a study of auditory evoked potentials, it is concluded that bilateral insular damage was crucial to both expressive and receptive components of the syndrome. The role of the insula in verbal and non-verbal communication is discussed in the light of anatomical descriptions of the pattern of connectivity of the insular cortex.

    Most research in modelling human information processing and decision making has been devoted to the case of the single human operator. In the present effort, concepts from the fields of organizational behavior, engineering psychology, team theory and mathematical modelling are merged in an attempt to consider first the case of two cooperating decisionmakers (the Dyad) in a multi-task environment. Rooted in the well-known Dynamic Decision Model (DDM), the normative descriptive approach brings basic cognitive and psychophysical characteristics inherent to human behavior into a team theoretic analytic framework. An experimental paradigm, involving teams in dynamic decision making tasks, is designed to produce the data with which to build the theoretical model.

    International Nuclear Information System (INIS)

    1994-12-01

    As part of ongoing US Nuclear Regulatory Commission (NRC) efforts to ensure the quality and accountability of safety issue information, the NRC established a program for publishing an annual report on the status of licensee implementation and NRC verification of safety issues in major NRC requirements areas. This information was initially compiled and reported in three NUREG-series volumes. Volume 1, published in March 1991, addressed the status of Three Mile Island (TMI) Action Plan Requirements. Volume 2, published in May 1991, addressed the status of unresolved safety issues (USIs). Volume 3, published in June 1991, addressed the implementation and verification status of generic safety issues (GSIs). The first annual supplement, which combined these volumes into a single report and presented updated information as of September 30, 1991, was published in December 1991. The second annual supplement, which provided updated information as of September 30, 1992, was published in December 1992. Supplement 2 also provided the status of licensee implementation and NRC verification of other multiplant action (MPA) issues not related to TMI Action Plan requirements, USIs, or GSIs. Supplement 3 gives status as of September 30, 1993. This annual report, Supplement 4, presents updated information as of September 30, 1994. This report gives a comprehensive description of the implementation and verification status of TMI Action Plan requirements, safety issues designated as USIs, GSIs, and other MPAs that have been resolved and involve implementation of an action or actions by licensees. This report makes the information available to other interested parties, including the public. Additionally, this report serves as a follow-on to NUREG-0933, ''A Prioritization of Generic Safety Issues,'' which tracks safety issues until requirements are approved for imposition at licensed plants or until the NRC issues a request for action by licensees

    Full Text Available Being developed countries both Pakistan and India are striving for the economic development. Pakistan and India share a 1610 km long border. They share same language, dress and culture and also six watercourses, namely the Indus, Jhelum, Chenab, Ravi, Sutlej and Beas, along with their numerous tributaries. Pakistan, like other countries of the region depends heavily on agriculture, with the greater part of the population relying on it for livelihood. As a result, water is not only vital for everyday needs, but a critical source for economic development. Water is a resource on which there is dependency of economy and no substitute. Pakistan and India are close neighbors and lied in South East of Asia. Apart from sharing border and history both the countries have various same customs and traditions.Both countries gained independence in 1947 from British Government, from the day of independence Pakistan has been facing lots of internal and external challenges. Apart from other conflicts, water issues also exist between Pakistan and India. After the nine years negotiation with the help of World Bank, they solved this issue but after some time it started again. Some kind of historical issues including water issues has been discussed in this paper. To judge the public opinion of the both countries, an interview survey was conducted by some international expert and from the people who are directly involved in these kind of profession of Indo-Pak relation. Analyses of interview with some statistic information and on the behalf of history some conclusions and suggestions were including at the end of this study.

    The aim of this study was to explore the influences on satisfaction with reconstructed breasts and intimacy following bilateral prophylactic mastectomy (BPM) in younger women (influence satisfaction. Communication with partners prior to BPM appeared to improve satisfaction with intimacy post-BPM. The findings suggest that satisfaction with reconstructed breasts for younger women post-BPM appeared to be influenced by realistic outcome expectations and communication with others concerning reconstructed breast appearance and intimacy post-BPM. Implications for practice include discussion of realistic reconstructed breast appearance, referral to a psychologist to discuss sensitive issues, and accurate communication of surgical risks and consequences.

    This paper proposes a cascade control scheme for delayed bilateral teleoperation of a quadcopter. The strategy transforms a 6D real quadcopter to an easy-to-teleoperate 3D virtual quadcopter. The scheme is formed by a P+d plus PID controller for each dof. The analysis based on Lyapunov theory gets as result the way to set the control parameters depending on the magnitude of the asymmetric time delays (forward and backward delays). This technic aims to reach stability, simplicity and good performance in practice. Besides, experimental tests about delayed bilateral teleoperation of a quadcopter including the proposed control scheme are shown in order to evaluate the system performance. Copyright © 2017 ISA.

    An omnidirectional mobile platform is designed for building point cloud based on an improved filtering algorithm which is employed to handle the depth image. First, the mobile platform can move flexibly and the control interface is convenient to control. Then, because the traditional bilateral filtering algorithm is time-consuming and inefficient, a novel method is proposed which called local bilateral filtering (LBF). LBF is applied to process depth image obtained by the Kinect sensor. The results show that the effect of removing noise is improved comparing with the bilateral filtering. In the condition of off-line, the color images and processed images are used to build point clouds. Finally, experimental results demonstrate that our method improves the speed of processing time of depth image and the effect of point cloud which has been built.

    Full Text Available Purpose: To report the efficacy of intravitreal dexamethasone implant in a patient with retinitis pigmentosa and bilateral cystoid macular edema unresponsive to topical carbonic anhydrase inhibitors. Case Report: A 36-year-old man with bilateral cystoid macular edema associated with retinitis pigmentosa that was unresponsive to topical carbonic anhydrase inhibitors underwent bilateral 0.7-mg intravitreal dexamethasone implants two weeks apart. Spectral domain optical coherence tomography revealed resolution of macular edema one week following each injection in both eyes and his visual acuity improved. However, macular edema recurred two months later in OS and three months later in OD. Second implant was considered for both eyes. No implant-related complication was experienced during the follow-up of seven months. Conclusion: Inflammatory process seems to play a role in retinitis pigmentosa. Intravitreal dexamethasone implant may offer retina specialists a therapeutic option especially in cases unresponsive to other treatment regimens in eyes with retinitis pigmentosa-related macular edema.

    Bilateral nephroblastomatosis (NB) is an uncommon renal anomaly characterized by multiple confluent nephrogenic rests scattered through both kidneys, with only a limited number of cases reported in the medical literature. Some of these children may have associated either Perlman or Beckwith-Wiedemann syndrome and others do not demonstrate syndromic features. We report a full-term boy with anteverted nose, bilateral bronchial stenosis due to lack of cartilage, bilateral obstructive renal dysplasia and NB with glomeruloid features. The infant had visceromegaly, but neither gigantism nor hemihypertrophy. Immunohistochemistry for PAX2 (Paired box gene-2) and WT-1 (Wilms Tumor 1) were strongly positive in the areas of NB. GLEPP-1 (Glomerular Epithelial Protein) did not stain the areas of NB with a glomeruloid appearance, but was positive in the renal glomeruli as expected. We found neither associated bronchial stenosis nor the histology of NB resembling giant glomeruli in any of the reported cases of NB.

    Full Text Available A 48-year-old woman was incidentally found to have bilateral adrenal masses, 2.8 cm in diameter on the right, and 2.3 cm and 1.7 cm in diameter on the left, by abdominal computed tomography. The patient had a medical history of hypertension, which was not being controlled by carvedilol, at a dose of 25 mg daily. She presented with signs and symptoms that suggested Cushing Syndrome. We diagnosed adrenocorticotropic hormone (ACTH-independent Cushing Syndrome based on the results of basal and dynamic hormone tests. Adrenal vein sampling (AVS was performed to localize a functioning adrenal cortical mass. AVS results were consistent with hypersecretion of cortisol from both adrenal glands, with a cortisol lateralization ratio of 1.1. Upon bilateral laparoscopic adrenalectomy, bilateral ACTH-independent adrenal adenomas were found. The patient's signs and symptoms of Cushing Syndrome improved after surgery just as the blood pressure was normalized. After surgery, the patient was started on glucocorticoid and mineralocorticoid replacement therapy.

    Full Text Available The aim - to compare the results of simultaneous bilateral and unilateral surgical correction of hallux valgus and to create recommendations for treatment of the patients with this pathology. Material and methods. The authorse analyzed the data of 40 patients (60 feet who carried out an operative treatment of hallux valgus in SPb multiprofile city hospital N 2 since 2011 to 2013. Functional (AOFAS score and X-ray results were compared between groups with bilateral and unilateral correction. Mean AOFAS score in these 2 groups after 12 months after surgery was 85,6±6,2 and 85,5±6,9 (p>0,05, mean intermetatarsal angle - 8,4±0,5° and 8,8±0,8° (p>0,05 respectively. No statistically significant difference between these two groups was found. Conclusion. A bigger surgical trauma in case of simultaneous bilateral correction neither worsens functional and x-ray results nor increases a complication rate.

    Lymphangioleiomyomatosis (LAM) is a rare, slowly progressive lethal lung disease primary afflicting young women. LAM is characterized by proliferation of abnormal smooth muscle cells that target the lungs, causing cystic destruction and eventual respiratory failure leading to death. Recent ten year mortality due to end stage LAM has been reported to be approximately 10%-20%, but may vary. The decline in lung function in LAM is gradual, occurring at a rate of about 3% to 15% per year but can vary from patient to patient. But recently therapy with mammalian target of rapamycin (mTOR) inhibitors such as sirolimus has shown promising results in the stabilization of lung function and reduction of chylous effusions in LAM. Lung transplantation is a viable option for patients who continue to have decline in lung function despite mTOR therapy. Unique issues that may occur post-transplant in a recipient with LAM include development of chylous effusion and a risk of recurrence. We describe a case of LAM recurrence in a bilateral lung transplant recipient who developed histological findings of LAM nine years after transplantation.

    Full Text Available Context: Anatomical localization of pituitary adenoma can be challenging in adrenocorticotropic hormone (ACTH-dependent Cushing's syndrome, and bilateral inferior petrosal sinus sampling (BIPSS is considered gold standard in this regard. Stimulation using corticotrophin-releasing hormone (CRH improves the sensitivity of BIPSS, however, same is not easily available in India. Therefore, we undertook this study of BIPPS using vasopressin as agent for stimulation owing to its ability to stimulate V3 receptors present on corticotrophs. Aims: To study the tumor localization and lateralization in difficult to localize cases of ACTH-dependent Cushing's syndrome by bilateral inferior petrosal sinus sampling using vasopressin for corticotroph stimulation. Settings and Design: Prospective observational study. Subjects and Methods: Six patients (5 females meeting inclusion criteria underwent BIPSS using vasopressin for stimulation. Results: All six patients had nonsuppressible overnight and low dose dexamethasone suppression test with elevated plasma ACTH levels suggestive of ACTH-dependent Cushing's syndrome. High dose dexamethasone suppression test showed suppressible cortisol in two cases, and microadenoma was seen in two patients on magnetic resonance imaging pituitary. Contrast enhanced computed tomography of the abdomen showed left adrenal hyperplasia in one case and anterior mediastinal mass with bilateral adrenal hyperplasia another. Using BIPSS four patients were classified as having Cushing's disease that was confirmed histopathologically following surgery. Of the remaining two, one had primary pigmented nodular adrenocortical disease, and another had thymic carcinoid with ectopic ACTH production as the cause of Cushing's syndrome. No serious adverse events were noted. Conclusions: Vasopressin may be used instead of CRH and desmopressin for stimulation in BIPSS.

    Makaruk, H, Winchester, JB, Sadowski, J, Czaplicki, A, and Sacewicz, T. Effects of unilateral and bilateral plyometric training on power and jumping ability in women. J Strength Cond Res 25(12): 3311-3318, 2011-The purpose of this study was to examine the effects of unilateral and bilateral plyometric exercise on peak power and jumping performance during different stages of a 12-week training and detraining in women. Forty-nine untrained but physically active female college students were randomly assigned to 1 of 3 groups: unilateral plyometric group (n = 16), bilateral plyometric group (BLE; n = 18), and a control group (n = 15). Peak power and jumping ability were assessed by means of the alternate leg tests (10-second Wingate test and 5 alternate leg bounds), bilateral leg test (countermovement jump [CMJ]) and unilateral leg test (unilateral CMJ). Performance indicators were measured pretraining, midtraining, posttraining, and detraining. Differences between dependent variables were assessed with a 3 × 4 (group × time) repeated analysis of variance with Tukey's post hoc test applied where appropriate. Effect size was calculated to determine the magnitude of significant differences between the researched parameters. Only the unilateral plyometric training produced significant (p 0.05) decrease power and jumping ability in all tests during detraining. These results suggest that unilateral plyometric exercises produce power and jumping performance during a shorter period when compared to bilateral plyometric exercises but achieved performance gains last longer after bilateral plyometric training. Practitioners should consider the inclusion of both unilateral and bilateral modes of plyometric exercise to elicit rapid improvements and guard against detraining.

  16. On the relative importance of bending and compression in cervical spine bilateral facet dislocation.

    Cervical bilateral facet dislocations are among the most devastating spine injuries in terms of likelihood of severe neurological sequelae. More than half of patients with tetraparesis had sustained some form of bilateral facet fracture dislocation. They can occur at any level of the sub-axial cervical spine, but predominate between C5 and C7. The mechanism of these injuries has long been thought to be forceful flexion of the chin towards the chest. This "hyperflexion" hypothesis comports well with intuition and it has become dogma in the clinical literature. However, biomechanical studies of the human cervical spine have had little success in producing this clinically common and devastating injury in a flexion mode of loading. The purpose of this manuscript is to review the clinical and engineering literature on the biomechanics of bilateral facet dislocations and to describe the mechanical reasons for the causal role of compression, and the limited role of head flexion, in producing bilateral facet dislocations. Bilateral facet dislocations have only been produced in experiments where compression is the primary loading mode. To date, no biomechanical study has produced bilateral facet dislocations in a whole spine by bending. Yet the notion that it is primarily a hyper-flexion injury persists in the clinical literature. Compression and compressive buckling are the primary causes of bilateral facet dislocations. It is important to stop using the hyper-flexion nomenclature to describe this class of cervical spines injuries because it may have a detrimental effect on designs for injury prevention.

    Wallis, Kate E; Blum, Nathan J; Waryasz, Stephanie A; Augustyn, Marilyn

    Sonia is a 4 years 1 month-year-old girl with Waardenburg syndrome and bilateral sensorineural hearing loss who had bilateral cochlear implants at 2 years 7 months years of age. She is referred to Developmental-Behavioral Pediatrics by her speech/language pathologist because of concerns that her language skills are not progressing as expected after the cochlear implant. At the time of the implant, she communicated using approximately 20 signs and 1 spoken word (mama). At the time of the evaluation (18 months after the implant) she had approximately 70 spoken words (English and Spanish) and innumerable signs that she used to communicate. She could follow 1-step directions in English but had more difficulty after 2-step directions.Sonia was born in Puerto Rico at 40 weeks gestation after an uncomplicated pregnancy. She failed her newborn hearing test and was given hearing aids that did not seem to help.At age 2 years, Sonia, her mother, and younger sister moved to the United States where she was diagnosed with bilateral severe-to-profound hearing loss. Genetic testing led to a diagnosis of Waardenburg syndrome (group of genetic conditions that can cause hearing loss and changes in coloring [pigmentation] of the hair, skin, and eyes). She received bilateral cochlear implants 6 months later.Sonia's mother is primarily Spanish-speaking and mostly communicates with her in Spanish or with gestures but has recently begun to learn American Sign Language (ASL). In a preschool program at a specialized school for the deaf, Sonia is learning both English and ASL. Sonia seems to prefer to use ASL to communicate.Sonia receives speech and language therapy (SLT) 3 times per week (90 minutes total) individually in school and once per week within a group. She is also receiving outpatient SLT once per week. Therapy sessions are completed in English, with the aid of an ASL interpreter. Sonia's language scores remain low, with her receptive skills in the first percentile, and her

    Full Text Available Background : A controversy exists regarding simultaneous or staged bilateral total knee replacement. Methods: Fifty patients undergoing simultaneous bilateral and 50 undergoing unilateral total knee arthroplasty were evaluated prospectively to compare the clinical, radiological results and complication rates. Eighty-four patients belonged to ASA category II or III preoperatively. The study included a high proportion of rheumatoid patients and osteoarthritis patients with severe deformities. Results: Bilateral group had greater blood loss and required more blood transfusion, but there was no difference in requirement of postoperative intensive care and the complication rates. Rheumatoid knees had lower pre and postoperative knee score and functional score as compared to osteoarthritic knees. Morbidity and mortality of one stage bilateral knee replacement was no greater than unilateral operation. Conclusion: Simultaneous bilateral knee replacement in younger patients with advanced rheumatoid arthritis is safe and effective
